Purchase Journal - Case Study Example Less attention on the goods and products needed for daily use. This creates pressure on the budget and sometimes the expenditure is not well planned. If goods for day to day use are not bought regularly and in a planned way, serious problems in consumption patterns may arise. The individual has spending power, but he is reluctant to buy the food products, fruits, vegetables, detergent, etc. This may give rise to health and hygiene problems. In the case too much money is spent to buy branded goods, there will be no funds left for medical emergencies, sudden price hike, etc. The expenditure is already high, so funds are being exhausted rapidly. It is necessary to revise the present purchase pattern. If the present purchase pattern is maintained, it will simply lead to financial mismanagement. However, the problem appears to be at a preliminary state. There is too much tendency of buying expensive, branded goods (this tendency can be checked, of course). No plan for significant savings discernable. More attention is needed on the daily expenses. The daily expenses must be focused to obtain a quality diet. Bank deposits or suitable investments at small scale are a good savings option. There should be more planning for a more economic living. The plans may include proper fund allocation, stoppage of buying expensive and sometimes unnecessary goods, investment in saving scheme,

Response & Recovery Essay Example | Topics and Well Written Essays - 1000 words

Response & Recovery - Essay Example After doing this, the second step I need to do is to perceive imposing hazards that can affect the safety of the people and the environment. This entails securing the area to prevent accidents and further casualties, which might eventually lead to evacuation of people or residents within and around the area of disaster; as well as the potential hazards that rescue personnel and the affected community may face (Emergency Management Institute – FEMA, n.d.). The following step that I need to do after the first two aforementioned steps have been undertaken is to set up initial priorities and urgent supply necessities which take on the need to process requirements in terms of equipment, personnel, facilities and supplies that will support the activities for response and recovery operations. This phase of the operation is quite critical because everybody involved needs to be on an equal footing that puts strict compliance to having personnel who are trained for such situations with knowledge in the use of common terminology pertaining to incident amenities; the position or title of designated supervisors/heads; the role of each present organization within the recovery operations; and the description of resources. ... It is vital to the whole operation that a chain and unity of command is established before the whole operation actually proceeds. This will enable every individual involved to report to a selected supervisor that I will be assigning, thus eliminating the possibility of being given several contradictory orders that can affect the smooth flow of communication and field work. Having a unity of command allows different agencies (local, state or federal) to work as a cohesive unit and effectively mete out the desired services as expected. There is also an essential need for responders to have and know entrance and exit routes, making the staging area an efficient workplace for everybody (Emergency Management Institute – FEMA, n.d.). Parallel to the abovementioned paragraph is the organization of priorities which I will do. The first priority is always the safety of all the personnel involved in the operation since another loss of life or another casualty may undermine the self-conf idence and self-esteem of the staff. Making the place of the incident safe from further damage is the second priority to do away with accidents and further loss of lives. The third priority is the preservation of property, where relief operation personnel implements procedures to safeguard possessions within the vicinity of the disaster (Emergency Management Institute – FEMA, n.d.). Likewise, I need to be very specific about the goals of the operation that must be finished within a specified timeframe or period. The goals must be realistic and feasible; and must be within the authority that was vested on me as Incident Commander (Emergency Management Institute – FEMA, n.d.). Additionally it is

Pepsi One Case Study Journal Essay Example for Free

Pepsi One Case Study Journal Essay PepsiCo, along with Coca-Cola, are two firms dominating the U. S beverage market with almost 76% collectively in 1998. This rivalry became more serious as PepsiCo released Pepsi One in order to increase its market. By properly applying the market audit, Pepsi One has succeeded in expanding the market, considered as a Pepsi core displays. Business structures of rivals, PepsiCo and Coca-Cola are virtually similar. As customers demand delicious products, firms have turned to marketing service companies, reducing their role as manufacturers. Its American operations have been transformed into sales and development markets. Innovation and technology departments are established, taking responsibilities of generating new products, packaging, and equipment. PepsiCo and Coca-Cola have the same business objectives which are strengthening brand image, expanding market, and beating their rivals in the beverage market, particularly for carbonated soft-drinks. PepsiCo’s marketing goal was to enhance customer’s awareness of its brand image, inform them about its new products, and reduce the consumer resistance to buy the products. In order to obtain these goals, PepsiCo has applied the market audit. Basing on the current results, it was founded that beverages with cola flavor witnessed a downward trend in sale as the customers were expecting a better tasting soft-drink. Hence, the concept for the new product was to develop a low-calorie drink that was similar to sugared soft-drink while avoiding the bitter aftertaste. Subsequently, by utilizing market analysis, particularly market segmentation and market targeting, the marketing department figured out who was going to be Pepsi One’s market. Pepsi One was then considered as a soft-drink for young men in their 20s and 30s who are afraid of the word diet and the bitter aftertaste. By conducting these tests, Pepsi believed their new product would reach a whole new audience. The role of marketing department in achieving PepsiCo’s marketing goals was undeniable since it is important to comprehend the market trend before launching a new product, the innovation and technology departments also had a significant role because being creative and to differentiate the products is markedly demanded in a highly competitive market. These departments advocated Pepsi One by using a unique marketing strategy to capture the market. At this point, the chairman of PepsiCo (1997) claimed â€Å"This is a real-time business, and we’re going to be a real-time company†. It is clear that Pepsi One flourished due to the contribution of these two departments. In conclusion, Pepsi One has succeeded in the soft-drink market. This is derived from understanding the market through market audit and using an appropriate market strategy. Pepsi One has helped its firm to gain the market and beat its rival Coca-Cola at low calorie soft-drink market.

The nyquist theorem is one of the deciding factor in data communication.

The nyquist theorem is one of the deciding factor in data communication. PART A Q1. The Nyquist theorem is one of the deciding factor in data communication. The fibre optics as well as the copper wires are communication mediums. Do you think the theorem is valid for the fiber optics or for the copper wires. Ans. Nyquist theorem is valid for both fibre optics and copper wires this is because the Niquist theorem is purely depend upon the mathematic function and has not any concern with the transmission media for communication. According to Henry Nyquist, a perfect channel has a finite transmission capacity. He derived an equation expressing the maximum data rate for a finite bandwidth noiseless channel. Nyquist said that if an arbitrary signal has been run through a low-pass filter of bandwidth B, the filtered signal can be completely reconstructed by making only 2Bsamples per second. Sampling the line faster than 2B times per second is pointless because the higher frequency components that such sampling could recover have already been filtered out. If the signal consists of L discrete levels, Nyquists theorem states: Maximum bit rate =2* Bandwidth log2 L. For noisy channel: Capacity = bandwidth * log2 (1+SNR), where SNR is signal to noise ratio. Q2. Noise affects all the signals which are there in air. There are some communicating modulation techniques. Noise affects which of the modulation technique the most. Ans. Noise is defined as the disturbance in the signal. When data is send over the network in the form of signal, due the various natural or unnatural circumstances produce disturbance in the signals which is called noise. The noise is various kinds such as thermal noise, crosstalk, and impulse noise. Noise affects all the signals but there are some modulation techniques which are used to reduce the noise. These techniques are: Amplitude modulation Frequency modulation Phase modulation The amplitude modulation is affected most by the noise this is because there is the change in only amplitude and the amplitude is affected easily by the noise. Q3. An analog signal carries 4 bits in each signal element. If 10,000 signal elements are sent per sec, find the Baud Rate and Bit Rate? Ans. Given signal carries r =4 Signal element s=10000 Let N be the bit rate We know that S = N*(1/r) à ° N= S*r à ° N= 10000* 4 à ° N=40000 bps Bit rate is equals to 40000bps Q4. What are the reasons for the imperfection caused in transmission media? How the perfection can be measured? Ans. There are certain reasons for the imperfection caused by the transmission media. These reasons are describe below: Attenuation: All the transmission media has some sort of loss of signal i.e. called attenuation which make then imperfect. During the transmission of the signal from one place to another the loss or energy is occurred which reduce the overall strength of the signals which is called attenuation. For this is reason amplifier is used in various place in the transmission. Noise: Noise is the basically the disturbance which is produced in the signal when the signal send over the transmission media then the natural and un natural climate affect the signal such as pollution etc.   So that some kind of distortion is occur in the signal. Every transmission media is affected with the noise which makes the signal imperfect. Distortion: Distortion means that the change in the signal. Due to some circumstance there must be change in the signal. The signal may deviate from actual one this is called distortion. The perfection can be measure in the form the above three. A transmission media which has less attenuation, less noise and less distortion that transmission media is called perfect. Q5. There are numerous multiplexing techniques available. What in your opinion is the most appropriate multiplexing technique for the fiber optics as well as copper wires? Ans. Multiplexing is the process of converting n signal to the one. There are various technique but two basic technique are FDM(Frequency Division multiplexing) TDM(Time Division multiplexing)   wavelength Division multiplexing In fiber optics multiplexing the best technique used is called WDM Wavelength division multiplexing. The basic principle of WDM on fibers is that n fibers come together at an optical chamber, each with its energy present at a different wavelength. The four beams are combined onto a single shared fiber for transmission to a distant destination. At the far end, the beam is spilt up over as may fibers as there were on the input side. Each output fiber contains a short special- constructed core that filters out all but one wavelength. The resulting signals can be routed to their destination or recombined in different ways for additional multiplexed transport. In the case of the copper wire Frequency division multiplexing technique is used. First the voice channels are raised in frequency, each by a different amount. Then they can be combined because no two channels now occupy the same portion of the spectrum. Notice that even though there are gaps (guard bands) between the channels, there is some overlap between adjacent channels because the filters do not have sharp edges. But nowadays there is use of the Time division multiplexing is used which is particularly deal with the digital signal. In this technique the conversion must be take place from analog to digital signals.   Q6. While transferring the data from the transmission medium there are various aspects of your data getting tempered by other users? Whats your opinion is the most secure and insecure transmission medium. Justify your answer with an example. Ans. Transmission media is the aspect which is caused for tempering of data by the other. All transmission media has this problem. When we use the copper wire it can be taped by another one. One of the improve version is the optical fibre which An improved media is fiber optic cabling, this media does not emanate any signals since it uses light sources to transmit the signals from node to node. It has proved to be the most secure media available for use on LANs today and will continue to be the most secure media until the black hats discover a way to tap it undetected. The last medium reviewed is the wireless media which uses the airways as their path from node to node. The only way to guarantee secure transmissions is to use a layered approach, or combination of techniques to try to encrypt the data. The best way currently to encrypt data over LANs is to use the IPSec protocol with any of the discussed media. IPSec security is compatible with all types of media so it is the one thin g in common with allmedia that will almost guarantee the security of the pathways between nodes. PART B Q1.Assume a stream is made of ten 0s .Encode this stream , using following encoding schemes .How many can you find for each scheme ? Unipolar NRZ-L NRZ-I RZ Manchester Differential Manchester Ans. 0 0 0 0 0 0 0 0 0 0 Unipolar: it can be drawn as: NRZ-L:   It can be drawn as: NRZ-I: it can be drawn as: RZ: it can be drawn as: Manchester: it can be drawn as: Differential Manchester: it can be drawn as: Q2. Two channels ,one with bit rate of 150kbps and another with a bit rate of 140kbps,are to be multiplexed using pulse stuffing TDM with no synchronization bits.Answere the following: What is the size of frame in bits What is the frame rate ? What is the duration of a frame? What is the data rate? Ans. Given bit rate of 1st channel=150 kbps Given bit rate of 2nd channel=140kbps Ans1. We allocate 3 slot for first and 3 slot for 2nd and we each size of frame is six bit. Ans2. Q3. Contrast   compare sampling rate received signal? Ans. In the conversion of the analog to digital, pulse code modulation is used. Sampling is the first stage of the PCM. The analog signal is sampled every Ts second. Where Ts is the sample interval or period. The inverse of sampling interval is called the sample rate or sampling frequency and denote fs where fs = 1/Ts. To produce the anolog signal one necessary condition is that the sampling rate be at least twice the highest frequency in the original signal. This is according to the Nyquist theorem. e.g. Wo well-known examples where sampled sound is used are the telephone and audio compact discs. Pulse code modulation, as used within the telephone system, uses 8-bit samples made 8000 times per second. In North America and Japan, 7 bits are for data and 1 is for control; in Europe all 8 bits are for data. This system gives a data rate of 56,000 bps or 64,000 bps. With only 8000 samples/sec, frequencies above 4 kHz are lost. Received signal strength is a measure of the power present in a received radio signal. RSSI is generic radio receiver technology metric which is usually invisible to the user of device containing the receiver but is directly known to users of wireless networking Q4. Synchronization is the problem in data communication. Explain? Ans. Synchronization technologies are designed to synchronize a single set of data between two or more devices, automatically copying changes back and forth. For example, a users contact list on one mobile device can be synchronized with other mobile devices or computers. Data synchronization can be local synchronization where the device and computer are side-by-side and data is transferred or remote synchronization when a user is mobile and the data is synchronized over a mobile network. In synchronous communications receiver, this specification discloses a decoder for generating a clock signal to synchronize the receiver with the information data rate of the received signal. The implementation of a decoder apparatus as a periodic finite state machine allows a clock signal to be extracted from the energy or transitions of the encoded signal. Such a decoder can define clock information over a large range of data rates. A band pass filter tuned to the characteristic frequency being re ceived can be coupled to the input of the decoder to limit the synchronization range to that desired by the receiver. Q5.Can bit rate be less than the pulse rate? Why or why not? Ans. Yes it is possible. Pulse rate is defined as the number of signals element send per second and the bit rate is defined as the number of data element which may be called bits in one second. Data communication needs to increase the data rate and decrease the pulse rate. So that the speed of transmission may be increased and decrease of bandwidth. But in some of the case it may be possible to the bit rate is less than pulse rate. This is done when the single pulse can carry more bits. When this happen the congestion Q6. A signal is sampled. Each sample represents one of four levels. How many bits are needed to represent each sample? If sampling rate is 8000 samples per second, what is the bit rate Ans. Given Sampling rate = 8000 We know that   bit rate   =1/Sample rate So bit rate =1/8000 =0.000125 bps

Performance Appraisal Essay -- Business, Employee Evaluation, Performa

Performance appraisals are a major component of human resource management systems used by organisations to measure and manage what is considered to be the most valuable resource available to them; human capital. This report aims to evaluate the effectiveness of performance appraisals and its application to both the employer and its employees, taking into consideration various rationales for its implementation. This will be achieved through an in depth review of the concept of performance appraisals, its evolution in corporate organisations and existing literature on the topic, and the effects (both positive and negative) to the organisation as a whole and to its employees. It will be argued that despite being of relative importance to performance management systems in organisations, performance appraisals fail to achieve the lofty ideals and objectives which characterize its implementation. Performance appraisals are a key component of the performance management process in organisations and are used to obtain feedback on performance levels of employees for a given period of time. Performance appraisals have been defined as the process which allows firms to measure and consequently evaluate an employee's achievements and behaviour over a certain period of time (Devries et al, 1981). It is the process of identifying, observing, measuring and developing human resources in organisations (Cardy and Dobbins, 1994). Various organisations use varying performance appraisal systems and have differing opinions on performance goals which cause some sort of confusion on the purpose of performance appraisal systems (Buckley and Wiese, 1998). Performance is thus the critical factor which is being addressed in the understanding and developmen... ...ughout the organisation. This way, management is able to consistently harmonize its operational goals with employee developmental efforts and job expectations. Performance appraisals also give organisations the opportunity to address performance issues without conflict by providing evidence of actual on the job performance and productivity. This way, high achievers and bottom performance are easily singled out with relative recommendations effected. Despite performance appraisals satisfying numerous organisational objectives, the focus of its activities is in providing direction and information to employees to boost performance and job productivity (Latham et al., 1993). This should remain the primary objective performance appraisal systems should seek to address which leads to this article addressing issues which affects the effectiveness of its implementation.

Gambling and the Brain Essay -- Biology Essays Research Papers

Gambling and the Brain Why do gamblers bet more after they just lost a hand? Why do investors throw good money after bad? Why do people believe that a string of losses makes a win more likely? Why do so many people say that they will win their money back in the next hand? Is part of the appeal of gambling its unpredictability? Or do we just look at it as a way to "get rich quick"? The answer to these questions may lie in the science of the brain. Some studies indicate that gamblers bet more after a loss because they are induced to fix an error. Their brains are telling them they've made a mistake and that they need to correct it (1). These studies could possibly explain other risky acts. If you ask many people why gamble, their response is "it is like a drug" (5). Compulsive gambling is a behavior which may rely on brain circuits that evolved to help animals assess rewards important to their survival. Researchers have found that those same circuits are used by the human brain to assess social rewards. They found that the brain systems that detect and evaluate such rewards generally operate outside of conscious awareness. The study said that much of what happens in the brain goes outside of conscious awareness. There are automatic brain circuits which affect activities such as gambling (2). However, this challenges prior notions which say that people make conscious choices about their everyday decision making. If people can get themselves to work unconsciously, how does the brain really know what it must pay conscious attention to? Also, how did evolution create a brain which makes such distinctions? Experiments performed on animals and humans are showing that the brain has evolved to shape itself according to what it e... ...times.com/ 3)Gambling has drug-like effect on brain,USA Today Newspaper article http://www.usatoday.com/news/health/2001-05-24-gambling.htm 4)Gambling—Like Food and Drugs—Produces Feelings of Reward in the Brain , Scientific American http://www.sciam.com/missing.cfm 5)You Bet Gambling Is Addictive , Business Week Online http://www.businessweek.com/bwdaily/dnflash/may2001/nf20010531_176.htm 6)The Good, the Bad, and the Anterior Cingulate, Science Journal, Science Magazine http://www.sciencemag.org/cgi/content/full/295/5563/2193a?maxtoshow=&HITS=10&hits=10&RESULTFORMAT=&fulltext=Gambling&searchid=1017881463081_295&stored_search=&FIRSTINDEX=0&fdate=3/1/2002&tdate=3/31/2002 7)The Medial Frontal Cortex and the Rapid Processing of Monetary Gains and Losses, Science Journal, Science Magazine http://www.sciencemag.org/cgi/content/full/295/5563/2279

Alternative Energy and Canadian Solar

The company we are focusing on is Canadian Solar. They are a multinational firm that operates in several countries such as â€Å"Canada, Germany, Italy, Japan, Korea, Spain, Australia and the United States†. They are a leader in the solar energy industry. A detailed PEST (Political, Economic, Social and Technological) analysis will be provided on how these elements affect the company. There are various political regulations and by-laws passed by the Canadian government to help regulate proper practices of using and installing solar energy. These regulations affect Canadian Solar and their practices.For instance, in the 1970s and 1980s there were a large number of solar panels installed that were not installed properly because they were added by unqualified people. Today there are strict regulations on getting the permission to install solar energy panels which protect land owners from liabilities. Permits must be attained from the government. This regulation protects Canadian Solar from any lawsuits from poor quality installation of solar panels or any damage to their customers’ property. This also helps them meet a certain standard of excellence to help their image and their customers.From 2007 to 2012 the world suffered a global recession. Canada was affected by it but not as severely as other countries worldwide. Economists say we are not in a recession but many Canadians believe otherwise. Although real GDP is adjusted for inflation, it is not for the growing population. This means â€Å"a country’s economy can be growing simply because the population is rising, and Canada’s population increases one percent a year†, which is misleading and does not tell the actual condition of the country.. This has affected Canadian Solar as well. Although they made a net profit in 2011, they made a net loss in its first quarter of 2012.Canadian Solar operates in other countries as well which were affected by the recession. For example, i n late 2007 China was affected by the recession, where their economy â€Å"plummeted by [forty] percent†. However, in 2012 Canadian Solar and Ningxia State Power, a Chinese based solar energy company, had completed a major project. This would help China â€Å"reduce CO2 emissions by 18, 900 tons annually – the equivalent of saving 5,200 tons of standard coal. † So although China was affected, companies are still progressing towards a healthier alternative of energy resource. Many Canadians believe solar energy is an excellent resource of energy.An advantage of using solar energy is there is no green house emissions and is friendly to the environment. However, onlyfifteen percent of sunlight is converted into energy which is not efficient for the amount it costs to install them. Although society agrees that solar energy is a healthy alternative to current resource of energy, it is very costly and inefficient. This affects Canadian Solar because depending on how s ociety feels. If the environment deteriorates much quicker than it is already, people will invest more in solar panels as a way to help the environment.If they do not care or feel the investment is not worth it, they will not buy. This affects the overall growth and stability of Canadian Solar. There has been much technological advancement in solar panels. The first solar panel was created by Charles Fritts in 1883 but could only convert less than one percent of sunlight into energy. . By 1954 a solar panel that could convert six percent of sunlight was created.. In the modern day Canadian Solar has made panels which can convert up to eighteen percent of sunlight into energy.The technological advancements have steadily improved in the solar energy industry and Canadian Solar is continuing to research and develop new ways to convert energy more efficiently. Encompassing Stakeholder map Government – Legislation is a key stakeholder interest for the company. Certain legislation can hurt or promote an industry which affects the companies within it. For example, in Ontario the provincial government passed the â€Å"Green Energy and Green Economy Act† which promotes the use of clean energy and promotes jobs. However, there is a lack of the right to light within Canada which affects those who want to use solar panels.This will be explained later. Employees – Employees want job security when working within an organization. Employees are an important stakeholder because they can affect the production and image of an organization, and at the same time are affected by the progress or deterioration of a company. If the organization is doing poorly that can affect the employees job security. Owners – Owners have an interest in the success of the company. These owners could be shareholders who have invested their money into the company in hopes of a positive return. Without their investments, these public companies have a lack of capital funding. Without proper decision making by management, these shareholders could lose everything they invested. Consumers – Customers are the foundation of businesses. Without them, a business cannot exist. Customers care about various things like customer service quality and the quality of the company’s product. If the product does not meet the standard of customers, they will not buy the product. Community – The community cares about environment and how solar energy will affect them. They want to make sure the product they are buying does not harm the environment and can be used to effectively harness sunlight as a form of energy.Specific Stakeholder Position Analysis The CEO of Canadian Solar is Dr. Shawn (Xiaohua) Qu. As CEO he holds several responsibilities and duties. He is considered the image of the company to both shareholders and the general public. If there are any disasters or public relation issues the media, stakeholders and general public will look to him f or answers. Although there are high ranking officials within the company to handle any public relation issues, it is up to him regarding where the company is heading towards.The decisions he makes can affect the company and other stakeholders who have stakes in the company. If Canadian Solar announces a major project which is long term and fails, the pressure is on the CEO. If the financial status of the company is poor, it concerns shareholders and they want to know why the company is failing. These responsibilities fall upon the CEO and it is up to him to determine whether certain projects are viable in the long term and how his decisions affect everyone around him.The federal and provincial governments are also stakeholders in the solar energy industry. The legislation they pass can hurt or harm the solar energy industry like Canadian Solar. There are various legal issues that come with harnessing sunlight as a form of energy. For example, in Canada there is no right to light. Al though you may have a solar panel installed around your home, you legally do not have the right to light. For example, a man in Ottawa installed a solar panel but â€Å"is now under threat from a near-by five-storey condo development†.This means that he cannot do anything to stop the construction of the condominium regarding his solar panel because there is no law for it in Canada. The lack of a right to light in Canada can affect many people who want to use solar energy as a source of energy but cannot because of obstacles like this. However the provincial government is making an effort to help encourage the use of alternative energy resources. On May 14, 2009 the Ontario government passed the â€Å"Green Energy and Green Economy Act† which encourages the use of â€Å"clean and renewable energy resources such as solar energy† and to create more jobs.The provincial government of Ontario has been trying to encourage the use of solar energy by passing legislation that helps promote the use of renewable, clean energy and promoting jobs at the same time. Customers are essential to the overall growth and long term development of companies. They are important stakeholders because companies depend on them in order to operate. In the solar industry, customers need to know that the product they buy is ethical, efficient and has quality.Customers are the foundation of companies and they make an overall impact on the organization. If boycotting occurs that would be a public relations disaster for them and can affect multiple things such as market share value and profits of an organization. They demand high quality, ethical and efficient goods. Customers believe solar energy is an excellent source of energy however because of the costs related to it and the lack of energy conversion. The industry needs to continuously try to improve their product in order to attract a larger market.
