Coca Cola Research Essay

3.3 Collect and review data using appropriate methods, including primary and secondary research techniques The researcher used the questionnaire method as his primary research technique. The survey questionnaire was adapted from a previous research done by an Advertising agency regarding effectiveness of advertising. This survey was then distributed online to a sample population within Metro Manila. And the secondary research technique that was used was from the study of Mr. Honorata Ocampo Lee which is about Comparison of the effectiveness of the physical distribution processess and strategies of Coca Cola bottlers Philippines Inc. and Pepsi Cola products Philippines Inc. in selected districts in Manila for the year 2001-2003. 3.4 Analyze and interpret appropriate qualitative and quantitative data Quantitative research uses a scientific approach; the researcher’s hypothesis which stated in his study will need to have an attempt in proving and disproving that hypothesis. The data that will be generated can be analyzed mathematically. (Primary and Secondary research) The researcher used questionnaire to Qualitative research is concerned with the opinions and feelings; the data that will be collected is not necessarily set of numbers. It looks at the overall image rather than the separate components. (Primary and Secondary research) 4.1 Record findings in an accepted format and 4.2 Present and summarize the findings using suitable methods 1. Please open the link to view the ad material. Have you seen this advertisement before? http://www.youtube.com/watch?v=oiu9PcEyQ5Y? Among the 50 respondents, 40 percent (20 respondents) said yes and 60 percent (30 respondents) said they haven’t seen the adver tisement yet. 2. How would you rate the overall quality of this advertisement? 40 percent of the respondents thought that the advertisement was good. 32% answered fair, 16% answered very good, and 12% answered excellent. None of the respondents answered poor. The data suggests that majority of the respondents thought of the advertisement as good enough or slightly above average. 3. How would you rate this advertisement compared with the others you’ve seen with familiar products/services? Majority (64%) of the respondents answered that the Coca-Cola advertisement was just â€Å"about the same† as other products’ advertisements. Meanwhile 20% answered that their ads were â€Å"A Little Better than the Others† and 8% thought that it was much better than the others. On the other hand 8% answered that the advertisement was a little worse than others. This data shows that, like the previous analysis, the Coca-Cola â€Å"Open Happiness† advertising comes across to the majority of the viewers as just average or slightly above average. 4. Are You Currently Using This Product A majority of the respondents (86%) said to be currently drinking Coca-Cola meanwhile 14% claimed that they are not currently using Coca-Cola. 5. After seeing this advertisement, would you want to buy this product? A majority (95%) of the respondents were still determined to buy the product after seeing the advertisement and 5% said that they would not want to buy the product. Up by 9% from the people who claimed to not have been using Coca-Cola at the moment, the data shows that the advertising has given an impact only to a small amount of respondents to buy Coca-Cola. However, the data also shows that regular consumers are still willing to purchase Coca-Cola even though the advertisement did not come out that strong, as shown from the results in the second question. 6. Have you ever used this product? The chart below shows that 100% or all of the respondents claim to have used or bought Coca Cola at one point in their lives. 7. Age Among the 50 respondents, 30 (40%) were within the ages 18-25, 8 (16%) were 26-30, 12 (24%) were 31-35, 5 (10%) were 36-40, 3(6%) were 41-45, and 2 (3%) were 46-50. 8. Gender The chart below shows that majority (68%) of the respondents are male and 31% are female. 4.3 Evaluate the methodology used and critically analyze the findings The researcher used the Questionnaire method. This method was chosen because using a questionnaire with a random sample is a good way to find out the attitudes, thoughts, and behaviors of a large group of people. The questionnaire that was used contained Close-Ended Questions. A set of choices was given to the respondents for them to be able to answer the questions. Aside from that, the researcher also chose to use Likert-Scales as this would be the basis to determine the level of effectiveness of the advertisements. Likert-scales consist of questions that would be answered by ranking them (Strongly Agree, Agree, Neutral, Disagree, Strongly Disagree) The method used would have been more effective if partnered with a select interview coming from each type of age group. The questionnaire method was proven effective in getting the opinions of the majority of the population. On the other hand, the interview method could have gotten more in-depth insights or feedback from the consumers regarding their opinion on Coca-Cola’s advertising and how it affects them as a consumer. 4.4 Propose recommendations based on the findings which identify and justify areas for future research Through the years, Coca-Cola had always come out strong in their advertising materials. Good examples of it would be Coke’s â€Å"It’s the Real Thing† and â€Å"I’d Like to Buy the World a Coke† during the 70’s and 80’s. These advertisements have helped propel Coca-Cola into it’s status now as the number one beverage company in the world. However for this decade, Coca-Cola’s â€Å"Open Happiness† Campaign didn’t come out as strong as their previous advertisements. They haven’t been as visible to the public eye as before. As shown in the first question, a majority of the respondents haven’t even seen the advertising material of â€Å"open happiness† before. This research has also helped prove that the advertising campaign of Coca-Cola now was rated just above average by the consumers. However, since Coca-Cola has managed to build up loyal consumers through the years, the statistics show that even though the advertising material may come out confusing or â€Å"just okay†, consumers will still continue to patronize Coca-Cola no matter what advertising material they produce. In spite of this, Coca-Cola should not be complacent with their current loyal customers. They should still invest in advertising campaigns that would appeal to their market. They should focus more on the younger generations as they are the group that is still trying to discover new products. Coca-Cola should be able to capture their loyalty for them to be able to sustain their position as the number one beverage in the world. References Questionnaires. (n.d.).

Gym Management System Essay

Introduction It is known that exercise is important. Exercise has a great impact in the body as it has all sorts of benefits. Physical activities are very helpful not only on making people fit but also on improving one’s personality. If they have a healthy body, they can be productive in daily life. Exercise increases the energy level. Through it delivers oxygen and nutrients to the whole body helping it to work more efficiently and boost endurance. It is also proven that regular exercise decreases the risk of health problems. Exercise can be fun. Physical activity releases chemicals in our brain called endorphins that are known to make you feel happier and relaxed. A thirty minute workout help improved moods and relieve stress. Doing physical activities are often great opportunity to socialize. Focus and motivation can be achieved to pursue goal which helps by going to the recreation center like going to gym to interacts and communicate with others. (http://primarychildrenshospitalblog.org/2012/06/12/10-reasons-why-exercise-is-important/). Fitness gym is one of the places they should visit to perform physical activities. This place has a facilities and equipments that you will use in our training session. There are trainers that give exercise programs and help you to become fit and strong. Every person in the world would like to have a perfect body. In order to have a healthy and a strong body, people would need to consider going to a gym to work out. What do such people expect of a gym? Certainly, patrons would expect a wide selection of equipment available in a gym. Patrons would enjoy well-educated staffs who know everything people want to know about working out. To provide a good quality of service to people, fitness gym should have an organized management system that will provide convenience to their staff to perform their work more efficiently.   The proposed system will give the list of exercises and it will keep records of gym members, attendance of gym employees, inventory and the payment of bills of the customers.

Definition of Terms For better understanding of the study, the following terms were defined: Administrator – a person responsible for running a business, organization,etc (https://www.google.com.ph/?gfe_rd=cr&ei=4DIVPbxDqHH8gffmoCIBg&gws_rd=ssl#q=administrator+definition). Exercise – activity requiring physical effort, carried out especially to sustain or improve health and fitness (https://www.google.com.ph/?gfe_rd=cr&ei=fE5_VKqECuOJ8QfHgYGQDw&gws_rd=ssl#q=meaning+of+exercise). Fitness Gym – it’s a place which houses the equipment  for the used in physical exercise. It is also the main purpose to create an automated Gym Management System. (https://www.google.com.ph/?gfe_rd=cr&ei=fE5_VKqECuOJ8QfHgYGQDw&gws_rd=ssl#q=meaning+of+Fitness+gym). Inventory – it’s a complete list of items such as property, goods in stock, or the contents of a building. This is also the key goal to automate this manual process. (https://www.google.com.ph/?gfe_rd=cr&ei=85eDVJb8MYeK8Qfn24Aw&gws_rd=ssl#q=inventory+definition). SQL Server – SQL Server is Microsoft’s relational database management system (RDBMS). It is a full-featured database primarily designed to compete against competitors. This is the database used in developing the proposed study. http://www.techopedia.com/definition/1243/sql-server CHAPTER II This chapter presents a summary of related literature and studies which were reviewed and evaluate by the researcher for the conceptualization of the study. REVIEW OF THE RELATED LITERATURE AND STUDIES GYM MANAGEMENT SYSTEM ACADEMIC It gives us great pleasure to present the project on â€Å"Gym Management† prepared sincerely, punctually and with utmost efforts. The contents of this book are presented into many chapters, in order to ease reading. The project has been illustrated with precise data elucidated with neat System Flowchart, dataflow diagram, Entity-Relationship diagram and Use Case diagram that simplify in understanding the software. The project includes the software development tools like c#, crystal reports to present the software very precisely. Meticulous care has been taken to make this project perfect and useful in every respect. ABOUT EXISTING SYSTEM The present system is totally depending on manual data management for different activities such as maintaining details of customer, supplier, Students etc. They maintain Different registers for various activities such as storing and searching data which is tedious and time consuming task. In present system all transactions are done manually with pen and paper so the frequent updating is not possible. Also generating reports, bills accurately  is not possible with current system. There are various other problems for instance, if customer come for the inquiry of particular Parcel and if that Parcel is not available then it is difficult to remember about it. In short system is lacking facilities such as searching, deleting, and adding data efficiently and effectively. DRAWBACKS OF EXISTING SYSTEM It utilizes a large amount of space for customer and supplier transaction information in paper files, Sometime manual calculation may be incorrect thus, leading to the incorrect information A large amount of data cannot be viewed at a glance No reminder for customer and Purchaser. Sometime the calculation has to be done manually so it requires a lot of work. Updating is not performed that efficiently and may lead complications. No security as data can be misplaced or damaged. Lastly, it was not offers a user friendly work environment NEED FOR NEW SYSTEM Working with current system is quite tedious, complicated and time consuming task. It may lead errors .certain operations such as surfing searching, adding, removing, entries cannot be done efficiently. Maintaining different registers for various activities such as storing and searching data which is tedious and time consuming task. Generating reports, bills are much tedious task with new system. Hence the organization needs new system with enhanced features. Features such as automatic report generation, bill generation, computing complicated calculations, performing operations such as adding, deleting, updating and searching etc. System should be user friendly. PROPOSED SYSTEM We hereby are grateful to present our software project through this report.Our proposed system is compute based. Which provide various User interfaces (Forms) for various operations and hence interactive. The system is able to generate calculations , bills ,reports automatically. Operations such as adding, removing, searching customers, suppliers and employees can be done efficiently and effectively by proposed system. Adding Parcels category and unit wise is possible with the help of this system. System can  efficiently perform various transactions such as sales, purchase and maintain data after each transaction. In short proposed system is user-friendly. FEATURES OF NEW SYSTEM GUI : The proposed system provides better graphical user interface Search : Searching details about customer, supplier, employee, Parcel is comparatively easy Increase Work Speed : Due to automation of some part of system work speed would increase Less Paperwork : For the proposed system less paperwork is required Reduces Error : Due to computerization there are less possibilities of error Economical : Due to minimal errors and work delay proposed system can be economically beneficial to the company http://www.projectcorner.in/gym-management-system-academic-project-c-net-synopsis/ Gym Management System Project Gym management system project is a standalone user friendly software application developed in asp.net using C# programming language and MS access database. Main objective: Main idea behind developing this project is to manage different types of data in fitness center, gym. Using this software we can manage employee attendance details, members payments, daily attendance, present and absent days of employees and members. Along with these details gym equipment and payments details are also managed. Gym Management System Project Modules Description: Equipment module: In this module we can add, delete, modify gym equipment details like when it is purchased, license , expiry date..etc. Instructor Module: This is also called as employee module where instructor profile details, experience, present and absent details for every day are updated. We can add , modify and delete these details, Member Module: Details of members who are joined are maintained through this application. Members salary, present and absent days details, payment , due information are managed through this module. Billing: Billing module helps in generating bills for members, employees for every month and provide due  payment details and we can generate reports for monthly billing. http://projectseminar.org/asp-net/asp-net-c/gym-management-system-project/554/ CHAPTER III Methodology of the Study The proponent choose the System Development Life Cycle as the methodology to fasten up the software development process. Method of Study To guide the researchers in developing the study, the proponent use SDLC (System Development Life Cycle) to meet user requirements in their business goals. SDLC is a series of steps and phases for the development of software. The phases of SDLC used are: (1) Data Gathering; (2) Analysis (3) Design; (4) Coding; (5) Testing and Evaluation. Data Gathering Phase is a collection of information that will be use to develop the system. The proponent studied the data needed by observing and conducting an interview. And in Analysis Phase is a process of collecting factual data, understand the processes involved, identifying problems and recommending feasible suggestions for improving the system functioning. This involves studying the business processes, gathering operational data, understand the information flow, finding out bottlenecks and evolving solutions for overcoming the weaknesses of the system so as to achieve the organizational goals. (http://oer.nios.ac.in/wiki/index.php/Phases_of_S ystem_Development_Life_Cycle). In Design Phase is based on the user requirements and the detailed analysis of a new system, the new system must be designed. This is the phase of system designing.   The logical design produced during the analysis is turned into a physical design – a detailed description of what is needed to solve original problem (http://oer.nios.ac.in/wiki/index.php/Phases_of_System_Development_Life_Cycle). In Coding phase is a system design needs to be implemented to make it a workable system. This is also called the programming phase in which the programmer converts the program specifications into computer instructions, which we refer to as programs. It is an important stage where the defined procedures are transformed into control specifications by the help of a computer language  (http://oer.nios.ac.in/wiki/index.php/Phases_of_System_Development_Life_Cycle). In Testing and Evaluation Phase is actually implementing the new system into operations, a test run of the system is done removing all the bugs, if any. It is an important phase of a successful system. After codifying the whole programs of the system, a test plan should be developed and run on a given set of test data. The output of the test run should match the expected results (http://oer.nios.ac.in/wiki/index.php/Phases_of_System_Development_Life_Cycle). Models Used in Developing the Software Used Case Diagram – It will show the role of each user of the system. In this diagram, we will learn the significance of each respondent on the flow of the system. Activity Diagram – Activity diagrams are graphical representations of workflows of stepwise activities and actions with support for choice, iteration and concurrency. In the Unified Modeling Language, activity diagrams are intended to model both computational and organisational processes (i.e. workflows) (https://www.google.com.ph/?gfe_rd=cr&ei=WBSEVMWnKyK8Qfkt4GwDg&gws_rd=ssl#q=activity+diagram+meaning). Database Schema – structure described in a formal language supported by the database management system (DBMS) and refers to the organization of data as a blueprint of how a database is constructed, divided into database tables in the case of Relational Databases (https://www.google.com.ph/?gfe_rd=cr&ei=WBSEVMWnKyK8Qfkt4GwDg&gws_rd=ssl#q=database+schema). Tools Used in Developing the Software Adobe Photoshop – it is a photo editing tool created by Adobe Systems Inc. The proponent used this software to enhance photos for the design of the Graphical User Interface of the system. Visual Basic 2010 – programming language created by Microsoft Company, the software that will be use to develop the proposed system. My SQL – is the world’s most popular open source database, enabling the cost-effective delivery of reliable, high-performance and scalable Web-based and embedded database applications (http://www.oracle.com/us/products/mysql/overview/index.html). Respondents of the Study The respondents of the study were IT specialist, Gym owners and clients who assessed the effectiveness of the product based on a set of criteria. The IT experts who will evaluate the system are IT people that have deep technical knowledge on the subject of this research. The Instrument A set of questionnaire was used in assessing the Gym Management system. Description The instrument called the Gym Management Assessment form is an assessment questionnaire. The items were categorized into the two factors: convenience and efficiency factors. Convenience factors were assessed based on three criteria: portability, security and maintainability. Efficiency factors, likewise, were assessed based on the three criteria of reliability, functionality and usability. Each criterion under each factor had 5 questions. Response Mode -Responses were categorized using a 5-point Liker Scale. Scale Description 5 -Strongly Agree 4 -Agree 3 -Moderately Agree 2 -Disagree 1 -Strongly Disagree Chapter IV Results and Discussion This chapter discussed the presentation, analysis and interpretation of all the data collected from the survey of the respondents as clearly stated in chapter 3. After reviewing, the method in this study, this chapter presented, analyzed and interpreted the data gathered from the survey questionnaire on UPHSD  Automated Clearance. Figure 1 illustrates the step-by-step development process that the proponent undertakes in developing the proposed system. Figure 2 Proposed System Development Flow These are the phases of system development strategy where both users and proponent engaged in the evaluation, design, and implementation. During the requirements planning and design phase, the proponents identify the objectives of the system and the information requirements arising from those objectives. These phase focused on reaching the project goals. During the first phase, the proponent is working with users intensely during the workshop to design the business or non-technical aspects of the system. As soon as these aspects are agreed upon and the systems are built and refined, a new system or part of the system are tested and then introduced to the Gym management. Use Case Diagram Use case diagrams are used to present a graphical overview of the functionality of a system.it is a type of static structure diagram that represents the user interactions with a system. This diagram portrays the different types of users and the various ways they interact with the system. In UML, the user is called actorand he can be human or an external system. The links between an actor and a use case are called associations. Use cases can be generalized, extended and included. Figure below contains the relationships and actors that illustrates and discussed the different set of structures of actions. Figure 3 Use Case Diagram Activity Diagram Figure Below exhibits thorough avctivity of registration of Gym Members and requires details to creat new account. Only the administrator can validate and verify the registration. Upon verification and approval new account is created. Figure 4 Activity Diagram Figure 5 Activity Diagram of User This figure shows the process flow of the User or the Gym Members. Once the user successfully logged on the system he/she can view the registration form, view of training programs, workouts, prices. He/she can also view his/her attendance. Figure 6 Activity Diagram for Administrator This figure illustrates the administrator different accessibility on the system. He/she plays a major role in this proposed system. He/ she will be the one who can access the registration of new members, viewing of the Attendance, work outs, trainings, transactions and also the generation of reports for this proposed system. Database Schema The figure below illustrates the database design and its entity relationship diagram of the different tables used in the database system. The diagram illustrates the one to one relationships among the table customers and customer transactions. The diagram demonstrates the relationship from one table to another. Figure 7 DataBase Schema Hardware Requirements This table below discussed the requirements of proposed system upon implementation. Category Specifications Architecture Dual Core Processor Processor Speed 1.10 GHz RAM 1gb Hard Drive 80 to 500 Gb sata Ethernet Adapter only supported ethernet adapter installed on computer Modem 56k Baud Rate Monitor Any Graphics Card Any Keyboard Any Mouse any Printer Any Chapter V Recommendations General recommendations The proponent brings up the significance of the proposed system along with the value of recommendations. The Gym Management System has attained its objectives. Thus the proponents recommend that the software must be implemented and can be adopted by any Gym or fitness business in reasons of it will allow the automation of manual process of membership registration, setting of workouts and training programs, viewing of attendance, transactions, inventory and generations of reports. This will speed up the manual process and gives effective, convenient and more reliable Gym Management System. The proponent chose the Software Development Life Cycle (SDLC) methodology to expedite the software development process. The SDLC provides structured  system development methodologies that guide the systems development effort toward quality systems that meet the user requirements and are delivered within time and budget. The traditional waterfall model has morphed into different methodologies that attempt to overcome some inherent weaknesses of this traditional model and other older models developed after the waterfall, which will be examined in the section below. This continued adaptation of the SDLC to meet current challenges in information systems development is expected to continue and is the crux of the validation of its continued relevance in information systems development. Some of these newer models include Structured Systems Analysis and Design Method (SSADM), Rapid Application Development (RAD) Extreme Programming (XP) Spiral, Fountain, rapid prototyping, incremental, and synchronize and stabilize. http://www.ukessays.co.uk/essays/computer-sciences/an-essay-on-the-sdlc-model.php The proponents used the descriptive narrative survey method to gather data. Statistical research describes data and characteristics about population or phenomenon being studied. Descriptive research answer the question who, what, where, when, now. The proponent selected 20 Gym members to serves as respondents of the proposed system. Performance will be acceptable to the end users requirements and delivering the system fully functional.  The study used the following statistical treatment; the distribution shows the number of responses obtained for each statement or item in the questionnaire. Conclusion The proponents came up with the following conclusion based on the findings: Based on the surveys and questionnaire the respondents came up that the Gym Management System is more effective and convenient to use. Registration, the response of the respondents is very effective with the weighted mean of 4.31; Log In, the response of the respondents is very effective with the weighted mean of 3.97; User Friendly Features, the response of the respondents is very effective with the weighted mean of 3.97; Inventory of Items, the response of the respondents is very effective with the weighted mean of 3.97; Generation of reports, the response of the respondents is very effective with the weighted mean of 3.97;

Central Group and Jirathivat Family Essay

Tiang Jirathiwat moved from China to Thailand with no asset. In 1947, he started a general store in in Samphanthawong district, Bangkok’s Chinatown. In 1957, his son, Samrit Jirathiwat, opened the first Central Department Store in Wangburapha and developed later on. In 1968, Central Silom was run with loss because people thought the imported items might be too expensive ! After two years, the Jirathiwats changed the strategy and made profit. Some family members (2nd Generation) were sent to study abroad and came back to develop Central Chidlom with Siblings and relatives. So, Central Chidlom made profit since its first year. Management Styles : First Generation : Tao Kae (concerned on cost of goods, loss and profit) Second Generation : Committee (concerned more on investment and finance) Third Generation : Family Council (development by family members under the family’s rules and regulations) The business transition from the first to the second generation was not complex, but from the second to the third generation was more complex, since nowadays there were much more business factors. For Central Group, which has been operating with many family members, there must be the rules and regulations besides the business issues. To be more focused on the third generation, they must work together and compromise â€Å"conservative† and with the â€Å"aggressive† styles ! Rotation and Distribution When to business turns to be more complex and operated by the larger numbers of family members, to make decisions is not simple. All Jirathiwats must know all A, B, C and D steps. Moreover, since the family members are graduated and have experiences in various fields, the work rotation and distribution are very efficient. Different families of Jirathiwats will work together, which leads to the family relation and unity. Jirathiwats is in charge of knowledge and experience of all family members. They focus both on â€Å"Drive and Control† as well as â€Å"Transition† of the family business. â€Å"The elements of strong business are Strategy, Money and People – money will bring strategies successful, but without good people, there won’t be an effective implementation†. (Tos Jirathiwat, CEO of CRC since 2002) Challenges In general family business, the CEO is wearing three hats; head of the family, business owner and the administrative CEO. This person must well balance all three actions, to be more specific, if he is focusing more on business issues, the family relationship can be weak. He should support the family members to be gradually evolved the business to make the members feel with this â€Å"family business† and are willing to involve of the business continuously. Hence, the conflict of interest will not be existing among the business performance and family harmony. This will make the transition to the next (4th) Generation the most possibly efficient. â€Å"The business competition is same as the war, which needs not only the individual ability but team work ! â€Å" Preventions â€Å"We must separate into two main issues; issues among family members and issues among stakeholders† (Tos Chirathivat, CEO of CRC since 2002) 1. Family Council From this reason, Family Council has been set in order to direct all Jirathiwats and give them rights and compensations. Here are some issues on Family Council : – Descriptions of a good member of Jirathiwat – The Rights that all Jirathiwats will receive, for instance, funds of birth giving, education, infrastructure expenses in family house, health care and hospitality. 2. Family Business Constitution Family constitution is strategies and solutions which should be implemented to deal with family-related matters that impact on business issues. It is necessary for family business to set regulations or rules in order to prevent conflicts that can happen. By the way, conflicts are the cause that creates regulation or rules. An effective Family Business Constitution might include: – criteria for joining the family business – a definition of roles – responsibilities of active – mechanisms to be adopted for the transfer of ownership and leadership. Jirathiwat Family also has a Family Constitution which will maintain harmony and co-operation, also solve conflicts. Agreements for family business are a clear, simple, understandable and enforceable set of guidelines for the effective operation and continuance of the enterprise. The 8 following issues are the Family Constitution of Jirathiwat, which seems to be very strict, but to link all family members together and to the family business: 1. All Jirathiwat families must stay in the same house, doing all activities together. 2. Everyone must respect in seniority, for example, parents will teach children, elder brother will teach his younger siblings. 3. Ranking is more important than age. 4. Democracy comes first and everyone has a right to express ideas. 5. All boys must be sent to Assumptions, girls to Mater Dei and everyone should be sent abroad. 6. The responsibities in business will be distributed to each, based on age, not seniority. 7. A bad action will be broadcasted to all family members as a bad example. 8. Instead of giving compliments, those persons who have good outcomes, will receive more business tasks and responsibilities. Lesson Learned Joel Arthur Barker said that â€Å"a set of rules and regulations (written or unwritten) that does two things† which are 1. It establishes or defines boundaries For Central: Everyone must have 6-year-experiences outside before coming back work with family 2. It tells you how to behave inside the boundaries in order to success For Central: Not doing business that competes with family business family business or relies on the mail family business. Prevention Before Solve – by setting regulations Put the right man on the right job – separate people up to their potential Last but not learst, as Jirathiwat has a policy in a form of â€Å"Executive Committee† operated by CEO group, business issues are apart from family issues. This is why they can have a strong family relationship, in the meanwhile, the business has been very well operated and continuously worldwide expanded only by family members.

Single Sex Education vs Co-Education Research Paper

Single Sex Education vs Co-Education - Research Paper Example Today, most of the single sex educational institutions in various countries have been converted into coeducation schools or colleges. However, the effectiveness of coeducation is still doubtful as many researches have pointed out the benefits of single sex education as well. It has been identified that single-sex education caters best to the academic achievement of girls. The present study, therefore, seeks to explore the various advantages and disadvantages of both single sex and coeducation systems of education and in doing so the paper deals with the history and growth of both the educational systems as well. Definitions It is worthwhile to understand the scope and significance of both single-sex and coeducation systems. Single-sex education is so designed to meet the educational needs of a particular sex only. As pointed out by Mael et al, â€Å"single-sex education refers most generally to education at the elementary, secondary, or postsecondary level in which males or females attend school exclusively with members of their own sex† (Mael et al ix). On the other hand, coeducation can be defined as an integrated system of education for both the sexes and as such the educational system is also known as mixed schooling. Coeducational system seeks to put an end to the educational disparities that prevail in communities and the ultimate aim of coeducation is to offer equal educational opportunities to everyone irrespective of one’s gender or sex. ... In this respect, Radford observes that it is the â€Å"social pressures to encourage cross-sex contact and socialization in a more ‘natural’ environment† that have promoted the growing number of co-education system since the 1960s (Radford 27). Early researches on co-education and single-sex education identified that co-education is highly beneficial for boys whereas there was no noticeable positive impacts on the academic achievement of girls. Studies have also shown that in terms of academic achievement single-sex education best suits for girls. Marsh et al merged one girls’ and one boys’ school into two co-educational schools and the results of the five-year longitudinal study revealed that the merger increased the self-concept of both sexes even though there was no considerable evidence in terms of better academic achievement (Radford 28). Another remarkable study conducted by Lee and Bryk in 1986 revealed that â€Å"girls in single-sex schools were more likely to associate with academically oriented peers, and have an interest in both mathematics and English† (Radford 29). On the other hand, there are many others who hold that coeducation facilitates socialization and that the system prepares girls towards social and democratic life. Therefore, it is imperative to identify which of the two systems best cater to the modern society and for this it is essential to make a probe into the pros and cons of both coeducation and single-sex education. Literature Review The literature review of the paper focuses on the history and growth of both coeducation and single sex education, evaluates the advantages and disadvantages of both the system, reviews the previous researches and studies on their pros and cons, evaluates the present day status of both

Making the case for employee wellbeing in a manufacturing organisation Thesis Proposal

Making the case for employee wellbeing in a manufacturing organisation - Thesis Proposal Example This paper briefly looks into the importance of employee wellness for a large manufacturing organization. In a large manufacturing organization, the employees function like the rings in a chain. As we know, if any one ring goes out of order or damaged in a chain the strength and cohesion of the chain will be lost. Same way in a large manufacturing organization the production processes are linked together. For example consider a tire manufacturing unit which normally may have three divisions; mixing, building and curing. If the mixing people fail to deliver the product in time, tire building will be affected whereas if the building people fail to complete their duties in time curing will be affected. Thus all the employees in a manufacturing unit complement each other in order to attain maximum productivity. â€Å"In situations where pressures to work longer hours are higher, where employees feel overloaded and where managers place stronger demands on personal time, employees are likely to experience greater dissatisfaction with their jobs, higher stress and fatigue, and greater work—life imbalance. (Macky, 2008) Employees under stress or bad health condition may underperform in an organization which will adversely affect an organization especially a big manufacturing organization. If one of the employees deliberately slows down things, it can affect the entire production activities of the unit. So there is nothing wrong in organizations investing heavily for developing or improving the facilities for the workforce at workplaces. Employees should feel a deep relationship with the organization in order to avoid unnecessary absenteeism or taking unnecessary sick leaves. If the employee considers the organization as his own, then he may refrain from activities which negatively affect the organization for which he is working. But in order to develop such deep relationship with the

Discussion Board 4-1 Assignment Example | Topics and Well Written Essays - 250 words - 5

Discussion Board 4-1 - Assignment Example Psychologists have used psychological theories and biological systems to explain the findings about relationship of media and antisocial behaviors in children. To begin with and with reference to Social Development and Social Learning theories, human beings mostly rely on their surrounding environments to learn more about life. Children have immature brains that eager and curious to explore and understand most of the events happening within their environments. Since unable to analyze and sort out information received within their environments, children are likely to consider what they see as right and correct (Cavanaugh & Kail, 2013). As such, children exposed to excess viewing of violent television programs and video contents are likely to lose empathy and instead develop merciless feelings that cause them become aggressive. Such children are likely to involve in reckless and undefined wars against others due to low problem solving abilities. Research findings conducted by psychologists using different theories of human development have also shown that playing violent games as has the potential to train children on complex tactics to become aggressive. Playing and wining video games also create the urge within children to involve in physical and practical exercising of their skills (Cavanaugh & Kail, 2013). To satisfy such urges, children have to involve their colleagues or any person to violence. A good example clarifying the effects of television and media on social behaviors of children occurred in 2006 immediately after hanging of Iraqi’s former President Saddam Hussein. As recorded by ABC News Medical Unit (2007), a nine years old Pakistani boy named Mubashar Ali hanged himself with the help of a ten years old sister. ABC News Medical Unit (2007) adds that after three days of Saddam’s execution, a fifteen years old Indian girl called Moon Moon Karmarkar committed suicide using a ceiling fan in the subu rb of Kolkata. All the children

Gilberto Vargas is an affluent Brazilian citizen who has lived in Rio Essay

Gilberto Vargas is an affluent Brazilian citizen who has lived in Rio since 1965. He is the controlling shareholder of a multina - Essay Example The test of connection that decides whether the person comes under the jurisdiction of UK taxation is primarily the test of residence (Baistrocchi, 2013, p. 2).The network that exists amongst the scores of double tax treaties (DTTs) forms an important part of the international law. The existing DTTs are all bilateral and based on two existing models; the OECD model and the UN Model. All the DTTs have stark similarities in terms of the topics covered, the order in which the topics are presented and the language in which the articles are described. This makes the DTT network such an important element in the tax regime, that the general rules have become a feature of the international law and might become binding in situations of governing taxation of income in cases of cross border transaction. This paper deals with the case of a Mr. Vargas who is a businessman and considers moving base to London for seven years. The OECD Model of DTT The DTT that follows the OECD Model is particularly applicable for the developed countries. It â€Å"reduces tax on royalties to zero but has a positive rate on interest and dividends† (Avi-Yonah, 2007, p. 3). There is harmful tax competition in which two issues are identifiable. Firstly, tax havens have been identified â€Å"as jurisdictions with no or nominal income taxes and also one or more of lack of effective exchange of information, lack of transparency, and lack of substantial activities by tax payers†. Secondly, preferential tax regimes have been identified as regimes that offer â€Å"no or low effective tax rate and one or more of ring fencing, lack of transparency, and lack of effective exchange of information† (Baistrocchi, n.d.). The prevalence of tax havens and preferential regimes has been condemned by the OECD which has stated it to be a harmful tax competition. The basis of taxation applicable for Mr. Gilberto Vargas: Arising basis or Remittance basis In the given case study, there is OECD Model based tax treaties between the relevant countries. Gilberto Vargas is the controlling shareholder of a multinational enterprise which is based in Brazil and holds investments in the real property market in Brazil, China and India. He is a citizen of Brazil and is considering a migration to the United Kingdom, along with family, for seven years. He is then a foreign national to the UK and his income is liable to taxation for only that amount that arises to him in the UK. The status of becoming a â€Å"resident in the UK† (Judgement, 2010, p.6) creates the platform for UK tax under the provisions of â€Å"Income Tax (Earning and Pensions) Act 2003† (Judgement, 2010, p.6). He is to be considered as a resident of the United Kingdom under the 183-day rule which states that if any person stays in the UK for one hundred and eighty three days, which is approximately half of a tax year (starting form 6th April of any year and continuing till 5th April of the next year) he is c onsidered a â€Å"resident in the United Kingdom† (BN1-British Citizenship, n.d., p. 5) for tax purposes occurring in that tax year. For the citizens of UK, unless a person spends the entire tax year outside the UK with no return visits to the UK, he would be treated as a resident of UK â€Å"for the tax years in which† (You are a UK resident taking a holiday or working holiday abroad, 2010) a citizen of the UK spends any time in the United Kingdom. But when the person is a non-UK domiciled, ie, his

Why are you passionate about leadership Essay Example | Topics and Well Written Essays - 250 words

Why are you passionate about leadership - Essay Example Hence, for me leadership is about the ability to interpret events and concepts in a way that allows for individual views, while making way for a sense of commonality and a shared sense of purpose. Doing so, a leader not only gives meaning to a collective vision, but also helps bring about the much needed alignment on strategies and goals. To me a leader is a person who ushers in an atmosphere of cooperation and trust by the dint of one’s personal integrity and charisma. Enterprises are always in the need of individuals who facilitate the quintessential backbone to the overall organizational culture, thereby ushering in a professional environment imbued with trust and integrity. The biggest source of satisfaction for a true leader is one’s ability to empower and enable people and groups. Leadership is about what happens when the leader is not present at the scene of action. So I hold that the biggest responsibility of a leader is to create an environment that motivates others to assume leadership and be willing to face

In this case, the principal will be legally bound by the actions the agency relationship which exists between agents-principals, agents-third and Principals-third parties and all the parties in the cycle are bound to the agreement, the agency cycle comprises of: Agent: this is the person who enters and performs duties and activities on behalf of the other person (the principal) with the third party and has authority to create a binding relationship or agreement between the principal and the third party. The agent negotiates, performs and enters into binding engagements on behalf of another person with the third party. Principal: This is the person who hires an agent to act on his/her capacity with the third party and is bound by the actions of the said agent in engagements with the third party. ... An agent must therefore operate within the instructions and capacity given by the principal and this will bind the principal in the contractual agreements he or she creates with the third parties which means that the law of agency is based on both implied and express terms. An agent has several duties he/she owes to the principal and must not act outside the scope or mandate provided by the principal. These duties can be summarized as below; The agent must ensure that he/she operates within the specified terms of agency agreement. If the agent ignores the directives of the principal in entering into an agreement with the third party then he/she will be held liable. The agent must therefore follow instructions given by the principal. The agent must carry out his/her duties with due diligence, skill and high level of professionalism to protect both parties from unnecessary breach of contract and subsequent compensation for the same, and this must be followed whether the agency agreemen t is written or oral.

K.Marx selected writting - Essay Example â€Å"†¦most people today would probably say that Marxism’s day is over, that Marx’s ideas have been proven empirically false and morally bankrupt, and that it is time to sweep away the remnants of Marx’s influence into the â€Å"dustbin of history.†(Introduction, ix) So, the ardent supporters of the cause of the labor had to revise their strategies, though lip-service continues to be paid to the ideology from different platforms even now. For Marx, labor is a commodity and needs to be evaluated thus. When Marx wrote about the alienation of labor, it was the most miserable commodity. Marx categorized the entire society into two classes: those with property and the one without property, who labor. In the Manuscripts titled â€Å"Alienated Labor† Marx deals with the basic causes of alienation. It takes place within the economic system of capitalism. â€Å"We now have to grasp the essential connection among private property, greed, division of labor, capital and landownership, and the connection of exchange with competition, of value with the devaluation of men, of monopoly with competition, etc., and of this whole alienation with the money-system,"(59) writes Karl Marx. The contention of Marx is political economy gives no proper explanation about the foundation of the division between labor and capital and also between capital and land. Interest of the capitalist assumes supreme importance. Another important aspect that eventually hurts the labor is competition. This is a mesmerizing tool with the capitalist that is important in successfully running the business. The other aspect of competition is greed and in the capitalist system it is the war of the greedy and aggrandizement of wealth. Labor, the â€Å"eternal natural necessity which mediates the metabolism between man and nature†, (223) is transformed into an alienated commodity to be bought and sold. With the advancement of the capitalist structure, the labor is denied most of the necessary objects,

Communication in careers, and The Self Essay Example | Topics and Well Written Essays - 1500 words

Communication in careers, and The Self - Essay Example I thought he is the right candidate for he is very friendly and open in his views. I was also interested in how hospitals are run; and Paul’s experience in this domain made him the ideal candidate. Paul is 47 years of age and works as a Human Resources Manager in a private hospital and what follows is the interview I had with him. Q. What were the greatest challenges you’ve met in your career so far? A. That’s an interesting question, for there is no straight-forward answer to it. I’ve risen to the current position as a HR Manager through a lot of hard work and perseverance. I began my career as an office assistant in a private hospital. From those humble beginnings I’ve now risen to a position where I am completely responsible for ensuring proper management of Human Resources in the hospital. It has not been an easy ride. There were times when I seriously doubted my compatibility to the profession. There were phases in which the monotony and drudge ry of work got the better of me and I seriously thought of quitting. In this respect, the biggest challenge I faced was finding creative ways of making work interesting. And by successfully managing to do so, I learned to apply creative thinking in other facets of life too, which is again a rewarding experience. Q. How important are communication skills to be a successful HR Manager? A. Very important. Indeed, clear and proper communication is essential in almost all professions, but its role is accentuated in the domain of HR. My responsibility as a HR manager is to communicate the vision and mission statements of the organization to all my subordinates. While textual dispersal of this information in the form of pamphlets and brochures is important, it is equally important to convey such messages in everyday interactions. In my years of experience, I learnt that leading by example is the best way to communicate the core philosophy of the hospital. In the private hospital that I wor k for presently, this philosophy is to put the interests of the patients ahead of profits. So the accounts department is notified of this priority, and thereby they are a bit lenient in billing patients from poor backgrounds. Q. How do you manage to make team members work in unison? A. I understand the importance of team ethic and try to inculcate it into my team members. There is an inherent contradiction here, for employees join the organization for fulfilling their personal needs, wants and aspirations. It would then be necessary that such personal motives do not overpower the needs of the hospital; and that employees try to synchronize their goals with that of organization’s goals. My job as a HR manager is to help them in this process, by suggesting and showcasing common ground between these two seemingly opposing tendencies. Q. What is the biggest change you’ve seen in communication methods and mediums in the last twenty years? A. There has been a tremendous chan ge in the way communication takes place these days. When I started out, telephones were the cutting edge in communications technology. But so much progress has happened since then. Today, we integrate personal medical records of all patients into an online-database, which can be cross accessed by physicians down the line. Technology has affected the diagnostic and prognostic procedures as well, making the quality of healthcare much improved.

Everyday Use by Alice Walker Essay Example for Free

Everyday Use by Alice Walker Essay Everyday Use by Alice Walker takes into account a central conflict between two women. This conflict is symbolized by two main characters; Mrs. Johnson and Dee. Both have certain characteristics are similar but mostly Alice juxtaposes these characters with each other to bring out the main theme of the play. Dee is an epitome of shallow materialism and an adherent of prevailing concept of heritage where heritage is revered only for trendiness and aesthetic attraction whereas Mrs. Johnson admires heritage for its practical utility and personal importance. Both Mrs. Johnson and Dee are from the same socio-cultural backgrounds but both are brought up in different cultural milieu. Both admire heritage but their motives are different. Mrs Johnson is ‘In real life I am a large, big- boned woman with rough, man-working hands’ (273) whereas Dee is soft-skinned and of delicate nature. Piedmont-Mortob is of the view that central conflict is between Maggie and Dee and â€Å"is about whether heritage exists in things or in spirit, or process. † Dee’s longing for heritage is for ostentatious reasons. For example she says, â€Å"I can use the chute top as a centerpiece for the alcove table†¦and I’ll think of something artistic to do with the dasher†. (277) Contemporary periodical necessities make her cherish and celebrate her Afro-American heritage. â€Å"Dee views her heritage as an artifact which she can possess and appreciate from a distance instead of as a process in which she is always intimately involved. † (Piedmont-Marton) But Mrs. Johnson and Maggie have learnt to live with their heritage. Dee is captivated by the beauty of â€Å"churn top† and wanted to have it to be used as centerpiece for her alcove table whereas Mrs. Johnson has used it practically for churn butter hitherto. Walker utilizes the butter churn to demonstrate Mrs. Johnson’s intrinsic understanding of heritage. When [Dee] finished wrapping the dasher the handle stuck out. I took it for a moment in my hands. You didn’t even have to look close to see where hands pushing the dasher up and down to make butter had left a kind of sink in the wood. In fact, there were a lot of small sinks; you could see where thumbs and fingers had sunk into the wood. It was a beautiful light yellow wood, from a tree that grew in the yard where Big Dee and Stash had lived. (277) About quilts Dee says: â€Å"Maggie can’t appreciate these quilts†¦ She’d probably be backward enough to put them to everyday use† (278) that shows her shallow reason to love her heritage. Mrs. Johnson says, â€Å"I am the way my daughter would want me to be†. (273) This is manifestation of her adoption to the changing circumstances. Same is the case with Dee as her pretensions about her culture are directly related to the changing social environment where heritage is celebrated and is not understood. The development of Dee into Wangero shows various facets and phases through which black identity passed during late 1960s and 1970s. Predilection for appearance as compared with spirit remained hallmark of this era and this trend is manifested through Dee’s transformation into Wangero. â€Å"Dee’s new name, her costume, and her new boyfriend (or husband) are all indicative of her frivolous attitude toward her newly adopted African culture. † (White) Above-mentioned arguments and supported evidence show that there exist similarities as well difference between the character of Mrs. Johnson and Dee. They love the same thing for different reason. Works cited Piedmont-Marton, Elisabeth. An Overview of Everyday Use. Short Stories for Students. Gale Research, 1997. Literature Resource Center.

Introduction To Beats Frequency Philosophy Essay

Introduction To Beats Frequency Philosophy Essay The sound of a beat frequency or beat wave is a fluctuating volume caused when you add two sound waves of slightly different frequencies together. If the frequencies of the sound waves are close enough together, you can hear a relatively slow variation in the volume of the sound. A good example of this can be heard using two tuning forks that are a few frequencies apart. A sound wave can be represented as a sine waves, and you can add sine waves of different frequencies to get a graphical representation of the waveform. When the frequencies are close together, they are enclosed in a beat envelope that modulates the amplitude or loudness of the sound. The frequency of this beat is the absolute difference of the two original frequencies Examples and applications of beat frequencies:- A good demonstration of beat frequencies can be heard in the animation below. A pure sound of 330 Hz is combined with 331 Hz to give a rather slow beat frequency of 1 Hz or 1 fluctuation in amplitude per second. When the 330 Hz sound is combined with a 340 Hz sound, you can hear the more rapid fluctuation at 10 Hz. Another example of beats:- When you fly in a passenger plane, you may often hear a fluctuating droning sound. That is a beat frequency caused by engine vibrations at two close frequencies. Application of beats:- A piano tuner will strike a key and then compare the note with a tuning fork. If the piano is slightly out of tune, he will be able to hear the beat frequency and then adjust the piano wire until it is at the same frequency as the tuning fork. If the piano is severely out of tune, it makes the job more difficult, because the beat frequency may be too fast to readily hear. Adding sine waves :- Although sound is a compression wave that travels through matter, it is more convenient to illustrate the sound wave as a transverse wave, similar to how a guitar string vibrates or how a water wave appears. The shape of such a wave for a single frequency is called a sine wave. Its fig isà ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦ in fig:- Here Sine wave represents a single frequency of sound with constant amplitude When we add sound waves traveling in the same direction together, elements of the sine wave add or subtract, according to where they are in the waveform. we add the amplitude of each wave, point by point. Making a graphical representation of the sum of two waves can be done by hand, but that can be be tedious. Beat envelope:- If we add two waves of slightly different frequencies, the resulting amplitude will vary or oscillate at a rate that is the difference between the frequencies. That beat frequency will create a beat envelope around the original sine wave. In this figure beat envelope modulates the amplitude of the sound Since the frequencies of the two sounds are so close and we would hear a sound that is an average of the two. But we would also hear the modulation of the amplitude as a beat frequency, which is the difference between the initial frequencies. fb = | f1 à ¢Ã‹â€ Ã¢â‚¬â„¢ f2 | where fb is the beat frequency . f1 and f2 are the two sound frequency. | f1 à ¢Ã‹â€ Ã¢â‚¬â„¢ f2 | is the absolute value or positive (+) value of the difference . Examples:- For example, if we add a wave oscillating at 445 Hz with one that is at 450 Hz, the resulting frequency will be an average of the sum of the two waves. (445 Hz + 450 Hz)/2 = 447.5 Hz. This waveform is close to a sine wave, since the frequency are almost the same. The amplitude of volume of this combination will oscillate at the beat frequency of the difference between the two: (450 Hz 445 Hz) = 5 Hz. Now, if we add 440 Hz and 500 Hz notes, the resulting waveform will be a complex version of a sine wave and will sound like a fuzzy average of the two tones. The average frequency of this complex wave will be (440 Hz + 500 Hz)/2 = 470 Hz. Also, its beat frequency will be 60 Hz, which would sound like a very low-pitched hum instead of a fluctuating volume. When two sound waves of different frequency approach your ear, the alternating constructive and destructive interference causes the sound to be alternatively soft and loud a phenomenon which is called beatingor producing beats. The beat frequency is equal to the absolute value of the difference in frequency of the two waves. -:Applications of Beats:- -:Envelope of Beat Production:- Beats are caused by the interference of two waves at the same point in space. This plot of the variation of resultant amplitude with time shows the periodic increase and decrease for two sine waves. The image below is the beat pattern produced by a London police whistle, which uses two short pipes to produce a unique three-note sound. Sum and difference frequencies Interference and Beats:- Wave interference is the phenomenon that occurs when two waves meet while traveling along the same medium. The interference of waves causes the medium to take on a shape that results from the net effect of the two individual waves upon the particles of the medium. If two upward displaced pulses having the same shape meet up with one another while traveling in opposite directions along a medium, the medium will take on the shape of an upward displaced pulse with twice the amplitude of the two interfering pulses. This type of interference is known as constructive interference. If an upward displaced pulse and a downward displaced pulse having the same shape meet up with one another while traveling in opposite directions along a medium, the two pulses will cancel each others effect upon the displacement of the medium and the medium will assume the equilibrium position. This type of interference is known as destructive interference. The diagrams below show two waves one is blue and the other is red interfering in such a way to produce a resultant shape in a medium; the resultant is shown in green. In two cases (on the left and in the middle), constructive interference occurs and in the third case (on the far right, destructive interference occurs. But how can sound waves that do not possess upward and downward displacements interfere constructively and destructively? Sound is a pressure wave that consists of compressions and rarefactions. As a compression passes through a section of a medium, it tends to pull particles together into a small region of space, thus creating a high-pressure region. And as a rarefaction passes through a section of a medium, it tends to push particles apart, thus creating a low-pressure region. The interference of sound waves causes the particles of the medium to behave in a manner that reflects the net effect of the two individual waves upon the particles. For example, if a compression (high pressure) of one wave meets up with a compression (high pressure) of a second wave at the same location in the medium, then the net effect is that that particular location will experience an even greater pressure. This is a form of constructive interference. If two rarefactions (two low-pressure disturbances) f rom two different sound waves meet up at the same location, then the net effect is that that particular location will experience an even lower pressure. This is also an example of constructive interference. Now if a particular location along the medium repeatedly experiences the interference of two compressions followed up by the interference of two rarefactions, then the two sound waves will continually reinforce each other and produce a very loud sound. The loudness of the sound is the result of the particles at that location of the medium undergoing oscillations from very high to very low pressures. As mentioned in a previous unit, locations along the medium where constructive interference continually occurs are known as anti-nodes. The animation below shows two sound waves interfering constructively in order to produce very large oscillations in pressure at a variety of anti-nodal locations. Note that compressions are labeled with a C and rarefactions are labeled with an R. Now if two sound waves interfere at a given location in such a way that the compression of one wave meets up with the rarefaction of a second wave, destructive interference results. The net effect of a compression (which pushes particles together) and a rarefaction (which pulls particles apart) upon the particles in a given region of the medium is to not even cause a displacement of the particles. The tendency of the compression to push particles together is canceled by the tendency of the rarefactions to pull particles apart; the particles would remain at their rest position as though there wasnt even a disturbance passing through them. This is a form of destructive interference. Now if a particular location along the medium repeatedly experiences the interference of a compression and rarefaction followed up by the interference of a rarefaction and a compression, then the two sound waves will continually each other and no sound is heard. The absence of sound is the result of the par ticles remaining at rest and behaving as though there were no disturbance passing through it. Amazingly, in a situation such as this, two sound waves would combine to produce no sound. location along the medium where destructive interference continually occurs are known as nodes. Two Source Sound Interference:- A popular Physics demonstration involves the interference of two sound waves from two speakers. The speakers are set approximately 1-meter apart and produced identical tones. The two sound waves traveled through the air in front of the speakers, spreading our through the room in spherical fashion. A snapshot in time of the appearance of these waves is shown in the diagram below. In the diagram, the compressions of a wavefront are represented by a thick line and the rarefactions are represented by thin lines. These two waves interfere in such a manner as to produce locations of some loud sounds and other locations of no sound. Of course the loud sounds are heard at locations where compressions meet compressions or rarefactions meet rarefactions and the no sound locations appear wherever the compressions of one of the waves meet the rarefactions of the other wave. If we were to plug one ear and turn the other ear towards the place of the speakers and then slowly walk across the room pa rallel to the plane of the speakers, then you would encounter an amazing phenomenon. we would alternatively hear loud sounds as you approached anti-nodal locations and virtually no sound as you approached nodal locations. (As would commonly be observed, the nodal locations are not true nodal locations due to reflections of sound waves off the walls. These reflections tend to fill the entire room with reflected sound. Even though the sound waves that reach the nodal locations directly from the speakers destructively interfere, other waves reflecting off the walls tend to reach that same location to produce a pressure disturbance.) Destructive interference of sound waves becomes an important issue in the design of concert halls and auditoriums. The rooms must be designed in such as way as to reduce the amount of destructive interference. Interference can occur as the result of sound from two speakers meeting at the same location as well as the result of sound from a speaker meeting with sound reflected off the walls and ceilings. If the sound arrives at a given location such that compressions meet rarefactions, then destructive interference will occur resulting in a reduction in the loudness of the sound at that location. One means of reducing the severity of destructive interference is by the design of walls, ceilings, and baffles that serve to absorb sound rather than reflect it. The destructive interference of sound waves can also be used advantageously in noise reduction systems. Earphones have been produced that can be used by factory and construction workers to reduce the noise levels on their jobs. Such earphones capture sound from the environment and use computer technology to produce a second sound wave that one-half cycle out of phase. The combination of these two sound waves within the headset will result in destructive interference and thus reduce a workers exposure to loud noise. Musical Beats and Intervals:- Interference of sound waves has widespread applications in the world of music. Music seldom consists of sound waves of a single frequency played continuously. Few music enthusiasts would be impressed by an orchestra that played music consisting of the note with a pure tone played by all instruments in the orchestra. Hearing a sound wave of 256 Hz , would become rather monotonous (both literally and figuratively). Rather, instruments are known to produce overtones when played resulting in a sound that consists of a multiple of frequencies. Such instruments are described as being rich in tone color. And even the best choirs will earn their money when two singers sing two notes i.e., produce two sound waves that are an octave apart. Music is a mixture of sound waves that typically have whole number ratios between the frequencies associated with their notes. In fact, the major distinction between music and noise is that noise consists of a mixture of frequencies whose mathematical relati onship to one another is not readily discernible. On the other hand, music consists of a mixture of frequencies that have a clear mathematical relationship between them. While it may be true that one persons music is another persons noise (e.g., your music might be thought of by your parents as being noise), a physical analysis of musical sounds reveals a mixture of sound waves that are mathematically related. To demonstrate this nature of music, lets consider one of the simplest mixtures of two different sound waves two sound waves with a 2:1 frequency ratio. This combination of waves is known as an octave. A simple sinusoidal plot of the wave pattern for two such waves is shown below. Note that the red wave has two times the frequency of the blue wave. Also observe that the interference of these two waves produces a resultant (in green) that has a periodic and repeating pattern. One might say that two sound waves that have a clear whole number ratio between their frequencies interfere to produce a wave with a regular and repeating pattern. The result is music. Another easy example of two sound waves with a clear mathematical relationship between frequencies is shown below. Note that the red wave has three-halves the frequency of the blue wave. In the music world, such waves are said to be a fifth apart and represent a popular musical interval. Observe once more that the interference of these two waves produces a resultant (in green) that has a periodic and repeating pattern. It should be said again: two sound waves that have a clear whole number ratio between their frequencies interfere to produce a wave with a regular and repeating pattern; the result is music. Finally, the diagram below illustrates the wave pattern produced by two dissonant or displeasing sounds. The diagram shows two waves interfering, but this time there is no simple mathematical relationship between their frequencies (in computer terms, one has a wavelength of 37 and the other has a wavelength 20 pixels). We observe that the pattern of the resultant is neither periodic nor repeating (at least not in the short sample of time that is shown). It is clear: if two sound waves that have no simple mathematical relationship between their frequencies interfere to produce a wave, the result will be an irregular and non-repeating pattern. This tends to be displeasing to the ear. A final application of physics to the world of music pertains to the topic of beats. Beats are the periodic and repeating fluctuations heard in the intensity of a sound when two sound waves of very similar frequencies interfere with one another. The diagram below illustrates the wave interference pattern resulting from two waves (drawn in red and blue) with very similar frequencies. A beat pattern is characterized by a wave whose amplitude is changing at a regular rate. Observe that the beat pattern (drawn in green) repeatedly oscillates from zero amplitude to a large amplitude, back to zero amplitude throughout the pattern. Points of constructive interference (C.I.) and destructive interference (D.I.) are labeled on the diagram. When constructive interference occurs between two crests or two troughs, a loud sound is heard. This corresponds to a peak on the beat pattern (drawn in green). When destructive interference between a crest and a trough occurs, no sound is heard; this corres ponds to a point of no displacement on the beat pattern. Since there is a clear relationship between the amplitude and the loudness, this beat pattern would be consistent with a wave that varies in volume at a regular rate. The beat frequency refers to the rate at which the volume is heard to be oscillating from high to low volume. For exà ¢Ã¢â€š ¬Ã‚ ¦, if two complete cycles of high and low volumes are heard every second, the beat frequency is 2 Hz. The beat frequency is always equal to the difference in frequency of the two notes that interfere to produce the beats. So if two sound waves with frequencies of 256 Hz and 254 Hz are played simultaneously, a beat frequency of 2 Hz will be detected. A common physics demonstration involves producing beats using two tuning forks with very similar frequencies. If a tine on one of two identical tuning forks is wrapped with a rubber band, then that tuning forks frequency will be lowered. If both tuning forks are vibrated together, then they produce sounds with slightly different frequencies. These sounds will interfere to produce detectable beats. The human ear is capable of detecting beats with frequencies of 7 Hz and below. A piano tuner frequently utilizes the phenomenon of beats to tune a piano string. She will pluck the string and tap a tuning fork at the same time. If the two sound sources the piano string and the tuning fork produce detectable beats then their frequencies are not identical. She will then adjust the tension of the piano string and repeat the process the beats can no longer be heard. As the piano string becomes more in tune with the tuning fork, the beat frequency will be reduced and approach 0 Hz. When beats are no longer heard, the piano string is tuned to the tuning fork; that is, they play the same frequency. The process allows a piano tuner to match the strings frequency to the frequency of a standardized set of tuning forks. Important Note:- Many of the diagrams on this page represent a sound wave by a sine wave. Such a wave more closely resembles a transverse wave and may mislead people into thinking that sound is a transverse wave. Sound is not a transverse wave, but rather a longitudinal wave. Nonetheless, the variations in pressure with time take on the pattern of a sine wave and thus a sine wave is often used to represent the pressure-time features of a sound wave. Whenever two wave motions pass through a single region of a medium simultaneously, the motion of the particles in the medium will be the result of the combined disturbance due to the two waves. This effect of superposition of waves, is also known as interference. The interference of two waves with respect to space of two waves traveling in the same direction, has been described in previous section. The interference can also occur with respect to time (temporal interference) due to two waves of slightly different frequencies, travelling in the same direction. An observer will note a regular swelling and fading or waxing and waning of the sound resulting in a throbbing effect of sound called beats. Number of beats heard per second Qualitative treatment:- Suppose two tuning forks having frequencies 256 and 257 per second respectively, are sounded together. If at the beginning of a given second, they vibrate in the same phase so that the compressions (or rarefactions) of the corresponding waves reach the ear together, the sound will be reinforced . Half a second later, when one makes 128 and the other  128*1/2 vibrations, they are in opposite phase, i.e., the compression of one wave combines with the rarefaction of the other and tends to produce silence. At the end of one second, they are again be in the same phase and the sound is reinforced. By this time, one fork is ahead of the other by one vibration. Thus, in the resultant sound, the observer hears maximum sound at the interval of one second. Similarly, a minimum loudness is heard at an interval of one second. As we may consider a single beat to occupy the interval between two consecutive maxima or minima, the beat produced in one second in this case, is one in each second. If the two tuning forks had frequencies 256 and 258, a similar analysis would show that the number of beats will be two per second. Thus, in general, the number of beats heard per second will be equal to the difference in the frequencies of the two sound waves. Analytical treatment:- Consider two simple harmonic sound waves each of amplitude A, frequencies f1 and f2 respectively, travelling in the same direction. Let y1 and y2 represent the individual displacements of a particle in the medium, that these waves can produce. Then the resultant displacement of the particle, according to the principle of superposition will be given by Y=y1+y2 This equation represents a periodic vibration of amplitude R and   frequency  . The amplitude and hence the intensity of the resultant wave, is a function of the time. The amplitude varies with a   frequency Since intensity (amplitude)2, the intensity of the sound is maximum in all these cases. For   to assume the above values like 0, p, 2p, 3p, 4p,. Thus, the time interval between two maxima or the period of beats = When the difference in the frequency of the two waves is small, the variation in intensity is readily detected on listening to it. As the difference increases beyond 10 per second, it becomes increasingly difficult to distinguish them. If the difference in the frequencies reaches the audible range, an unpleasant note of low pitch called the beat note is produced. The ability to hear this beat note is largely due to the lack of linearity in the response of the ear. Demonstration of beats:- Let two tuning forks of the same frequency be fitted on suitable resonance boxes on a table, with the open ends of the boxes facing each other. Let the two tuning forks be struck with a wooden hammer. A continuous loud sound is heard. It does not rise or fall. Let a small quantity of wax be attached to a prong of one of the tuning forks.. This reduces the frequency of that tuning fork. When the two forks are sounded again beats will be heard. Uses of beats:- The phenomenon of beats is used for tuning a note to any particular frequency. The note of the desired frequency is sounded together with the note to be tuned. If there is a slight difference in frequencies, then beats are produced. When they are exactly in unison, i.e., have the same frequency, they do not produce any beats when sounded together, but produce the same number of beats with a third note of slightly different frequency. Stringed musical instruments are tuned this way. The central note of a piano is tuned to a standard value using this method. The phenomenon of beats can be used to determine the frequency of a tuning fork. Let A and B be two tuning forks of frequencies fA (known) and fB (unknown). On sounding A and B, let the number of beats produced be n. Then one of the following equations must be true. fA fB = n à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦. (i) or fB fA = n à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦. (ii) To find the correct equation, B is loaded with a little wax so that its frequency decreases. If the number of beats increases, then equation (i) is to be used. If the number of beats decreases, then equation (ii) is to be used. Thus, knowing the value of fA and the number of beats, fB can be calculated. Sometimes, beats are deliberately caused in musical instruments in a section of the orchestra to create sound of a special tonal quality. The phenomenon of beats is used in detecting dangerous gases in mines. The apparatus used for this purpose consists of two small and exactly similar pipes blown together, one by pure air from a reservoir and the other by the air in the mine. If the air in the mine contains methane, its density will be less than that of pure air. The two notes produced by the pipes will then differ in the pitch and produce beats. Thus, the presence of the dangerous gas can be detected. The super heterodyne type of radio receiver makes use of the principle of beats. The incoming radio frequency signal is mixed with an internally generated signal from a local oscillator in the receiver. The output of the mixer has a carrier frequency equal to the difference between the transmitted carrier frequency and the locally generated frequency and is called the intermediate frequency. It is amplified and passed through a detector. This system enables the intermediate frequency signal to be amplified with less distortion, greater gain and easier elimination of noise Summary:- A beat frequency is the combination of two frequencies that are very close to each other. The sound you hear will fluctuate in volume according to the difference in their frequencies. You may often hear beat frequencies when objects vibrate. Beat frequencies can be graphically shown by adding two sine waves of different frequencies. The resulting waveform is a sine wave that has an envelope of modulating amplitude.

The Emerging Technology Trends In Computer Hardware Information Technology Essay

The Emerging Technology Trends In Computer Hardware Information Technology Essay The future of computer hardware is very fragile due to problems between software and hardware engineers and software now that cannot keep up with the material; the material may be decreasing as the software has priority. One thing to note is that the material cannot be totally eliminated. The market will always be a demand for faster hardware, lighter, more coherent and comprehensive. Arguably, the material can not hire as many jobs as the software does now because of the need and progress in software technology related to technology equipment. The material is and will carry on generating new applications that will make life easier and business more flourishing. Apply a new type of technology used in hardware applications, known as COTS. Commercial and product standards commonly known as COTS are proven and reliable in changing computer world. COTS allow software developers to provide new products, and hardware platform for adding custom hardware; a new device is the latest USB standard is also a past director of external equipment transfers. Cots are devices to help correct answers and progress on new computers, such as the XML protocol and new wireless advances. Another technology is the new hardware unit is microcontroller. The micro-controller unit (MCU) complete final products to the automotive market for smart cards. 16-bit and 32-bit MCU + are the main products of high-end consumer, the automotive and industrial control equipment. MPU Base application and wide variety of entrenched memory and other technologies add to their permanent unit and revenue growth. MCUs will carry on to see their make use of in products outside the home machine, which will allow hardware developers in the right direction for diversified applications. The tension between hardware engineers and software has led to an interesting correlation. Both types of engineers must learn to work together because the software and hardware engineers need each other in an appropriate communication to achieve various objectives. The types of material that is developed must cease and forth between the phase of software development for all types of applications across the board for all the different courses. With the increase in CPU capacity, created the software will always take more than enough room to allow the continued growth of the CPU in the industry. In the research project is completed, the balance between hardware and software engineers stay just as important for the optimal completion. Trends in computer software In an interview with John Bruggeman, Chief Marketing Manager, Wind River, a software design company based in the United Kingdom, which explains how the software has grown much faster than hardware applications. Bruggeman specialized software in Linux, which has seen faster growth than expected. For us the Linux business has grown from zero to 50 million dollars in 24 months. Not only Linux, but Amazon has created a unique opportunity to expand. Amazon Web Services has launched a new enterprise IT management software products, which include the rental of servers, instead of forcing companies to buy directly from a number of expensive servers. Technology recently published an article So far the market has taken the idea of Amazon and Amazon has shown that Web services have already won clients such as The New York Times, Red Hat and SanDisk. Other companies, like IBM and Sun are struggling to move to a new model. Sun already offers online rental system and expects to sell the equipment. We have the infrastructure, says Greg Papadopoulos, chief technology officer of Sun If you do not you can beat them, their hand. Suns final report shows that the Amazon Web Services functions have hit a new market that will continue to be successful. What are the current trends in computer hardware platforms and the evolving mobile platform, grid computing, and cloud computing? Mobile platform: more and more business computing is moving from PCs and desktop machines to mobile devices like cell phones and Smartphones. Data transmissions, Web surfing, e-mail and instant messaging, digital content displays, and data exchanges with internal corporate systems are all available through a mobile digital platform. Net books, small low-cost lightweight subnotebooks that are optimized for wireless communication and Internet access, are included. Grid computing Grid computing combines computer from systems multiple administrative domains to achieve common aims to solve a simple task and can disappear very fast. A grid computing key strategies is to use middleware to divide and distribute pieces of a program between several computers, sometimes up to several thousands. Grid computing is to compute in a distributed manner, which may also involve the aggregation of cluster systems based on large computer companies. The size of a grid can vary from a small restricted to a network of computer workstations in an enterprise, as for large public works across many companies and networks. The idea of a limited network may also be known as an intra-node, while the idea of bigger, wider networks may refer to inter-nodes. The grids are in the form of distributed computing; where the super virtual computer is composed of many networked computers to perform tasks freely collaborate large. This technique has been applied to computationally intensive problems in science, math and academic volunteer computing, and is used by commercial enterprises, such as various applications such as drug development, economic forecasting, seismic analysis and back-office data processing, support for e-commerce and web services. Grid computing gives a safe way to solve Grand Challenge issues, like proteins, financial modeling, earthquake simulation, weather patterns. The grid provides a way to use IT resources optimally inside an organization. They also offer a means of providing information for their technology and commercial business customers, with customers paying only for what they use, such as water and electricity. Grid computing is used by the grid of the National Science Foundation, National Technology, NASAs Information Power Grid, Pratt Whitney, Bristol-Myers Squibb Co. and American Express. The European Union has been a great supporter of grid computing. A lot of studies and projects have been funded by the European Commission Framework Programme. Lots of projects are emphasis here, but 2 of them deserve special point out: Enabling Grids BEinGRID and for e-Science. Business Experiments in GRID is a project, and also have a 1/4th amount of the whole project is funded by the European Commission as an incorporated Project under the 6th Framework Programme Sponsorship Program (FP6). Introduced in June 2006 and the project lasts for 2 years, until November 2009. The research is organized by the Atos Origin. According to the project sheet is their mission to create effective ways to promote the adoption of grid computing across Europe and to stimulate research on innovative business models using Grid technologies. Extracting best practices and common themes of the experimental implementations, two groups of consultants to analyze a number of pilots, technique and business. The results of this cross analysis provided by the TI website called www.tude.com. The project is important not only for its longevity, but also for its financial plan to 24.8 million Euros, is the greatest of all integrated projects in FP6. The grids of the E-science, which is founded the European Union and also sites in USA and the most part of the Asian continent, is a follow-up project of the European DataGrid (EDG), and is probably the largest computer network on the planet. This, together with the LHC Computing Grid (LCG) was developed to support the experiment at the Large Hadron Collider at CERN. LCG Project at CERN is based on the need to handle large amounts of data, where the rates are required to store several gigabytes per second. A list of active sites within LCG can be found online as well as real-time monitoring of the EGEE infrastructure. The software and documentation is also accessible to the public. It is speculated that optical fiber dedicated links, such as those installed by CERN to meet the needs of large volumes of data from the LCG may one day be available for home users and Internet service reach very fast approximately a thousand times faster than the usual broadband internet connection. Until April 27, 2007, United Devices United Devices Cancer Research Project based on its Grid MP product, which cleans the PC cycle of volunteering over the Internet. Grid MP in June 2005 ran about 3000000 machines. Cloud computing Cloud computing is computing on the Internet where shared resources, software and information is provided for computers and other devices on demand, with the grid. Cloud computing is a natural change of the well known to use of virtualization, SOA and utility computing. The details are extracted from consumers who no longer required specialized knowledge or control over the technology infrastructure that supports the tag. Cloud computing describes a new addition, consumption and delivery model for IT services Internet-based and are generally over-the delivery of Internet resources dynamically evolving and often virtualized. This is a result of product and ease of access to computer sites that offer Internet distance. This is mostly takes the form of internet based applications and tools that users can access and get use through an internet website browser as if it were a program installed locally on your own computer system. NIST provides a definition a little more objective and specific here. Tag word as a metaphor for the Internet based on the design previously used tags to represent the telephone network, and then to describe the patterns of Internet computer network as an abstraction that represents the underlying infrastructure. A typical cloud computing provider to provide common business applications online that is accessible from another web service or software as a Web browser, while the software and data stored on servers Most cloud computing infrastructure consists of services offered by the centers joint and integrated servers. Clouds often appear as single point of access to the computing needs of consumers. Commercial facilities are generally required to meet Quality of Service (QoS) of clients, and generally include service level agreements (SLA). The big cloud providers include Amazon, Microsoft and Google. Some large IT companies who are actively involved in cloud computing, Fujitsu, Dell, Hewlett Packard, IBM, VMware, NetApp and Microsoft. There are several doubts and confusions in relation to the phrase called hybrid when applied to the cloud a criterion description of the word hybrid Cloud has not yet risen. Cloud term hybrid has been used to assign 2 clouds. Separate conference ( private, public external or internal ) or a blend of clouds virtualized server instances that are used in combination with the actual physical hardware. The correct definition of the term hybrid Cloud; is probably the use of physical hardware and virtualized server instances tag together to provide a unique and common. Two clouds were collected are more properly a combined cloud. A combined cloud computing environment composed of multiple combined internal or/and external suppliers would be typical for most companies By integrating cloud computing services to multiple users to facilitate the transition to the public cloud services while avoiding problems such as PCI compliance. Another perspective on the implementation of a web application in the cloud using hybrid Web hosting infrastructure is a mix between Cloud hosting and dedicated servers it is usually implemented as part of a Web cluster, where some nodes running real physical hardware and some running on the server where the clouds. How network economics, declining communication costs and technology standards affect IT infrastructure? Network economics: Economics refers to the Business Network, which will benefit from the network. This is where the value is a good or service increases as more people buy the product or service. Examples include websites like eBay, or if the iVillage community together and share ideas to help the website become a better business organization. Metcalfes Law explains the proliferation of computer use by showing that the value of network participants grows exponentially as the network becomes more members. As the number of members in a network increases linearly, the values of the overall system grows exponentially and theoretically continue to grow indefinitely with increasing membership. Declining communication costs: The communication costs are rapidly falling down daily. The costs of communication and the exponential growth in the size of the Internet is a driving force that affects the IT infrastructure. When there is a decline happened in the communication cost will reflect several advantages and disadvantages to the information technology infrastructure. The main advantage of decline of communication costs is when its get fall to a very small and approaches zero, the use of communications and computer exploits. Technology standards: According to the growth of IT industry, the standards of design and communication is getting improved and more competitive day by day. Technology standards and economies of scale release powerful lead to decreases in the prices that manufacturers focus on products manufactured by a single standard. No economies of scale, the information of any kind would be much more expensive than is the case today. Creating and maintaining a coherent IT infrastructure raises multiple challenges including: Making wise infrastructure investments, IT infrastructure is a major investment for the company. If too much is used for infrastructure will not be used to form drag its financial performance. If it is too little used, a major business services cannot be delivered and competitors of the companys better than investing in the company. Coordinating infrastructure components: attempts to create IT infrastructures, select a combination of vendors, people and technology services and fitting them together so they operate in a coherent whole. Dealing with scalability and technology change: as companies grow, they can easily find that their infrastructure. As companies shrink, they can get stuck in too much infrastructure has been purchased in better times. Scalability: the ability of the computer of a product or system expansion to serve more people without breaking down. Leadership and management: refers to who controls and manages the IT infrastructure.
