Title of the Paper ( Court Case Briefing/Analysis ) Submitted By ( Zaevon Prince, PrinceZ0924 @students.bowiestate.edu) Number and Name of Course (Criminal Justice Victim Crime Justice- CRMJ 315 ) Class Meeting Time/Day (T: 7:35 P .M. - 10:00 P .M.) Professor (Dr. Donine Carrington ) Semester (Fall 2016) Today's Date (Thursday December 15 , 2016) Bowie State University Department of Criminal Justice Arts Science Bowie, Maryland The case of Fernandez v. California ( 134 S. Ct. 1126) involves the issue of The Fourth Amendment rules governing a police investigation of a crime, (Pet.Brief 2). On October 12, 2009, Abel Lopez was approached by a man, whom Lopez later identified as petitioner, after he had cashed his check. Petitioner told Lopez that he was in petitioner's "territory" and demanded Lopez's money (Pet. Brief 2). Officers Joseph Cirrito and Kelly Clark drove to a nearby alley. As the officers stood in the alley, two men walked by. One of them, who appeared frightened, told the officers, "the guy is in the apartment." After walking away quickly, the man returned and said, "He's in there. He's in the apartment." Officers Cirrito and Clark then saw a man run across the alley and enter the house identified by the man (U.S. Brief 2). Officer Cirrito "heard sounds of screaming and fighting from the apartment building into which the suspect had run." After an additional officer arrived, t he two main officers on the scene went to knock on the door from where the screaming came and Ms. Roxanne Rojas, who was holding a baby, opened the door. She appeared to be crying; her face was red; she had a "big bump" on her nose; and she had fresh blood from an injury on her shirt and fresh blood on her hand (U.S.Brief 3). Cirrito asked Rojas to step outside so that he could "conduct a sweep of the apartment". The turning point had been when petitioner came to the door. He was dressed in only boxer shorts, was sweaty and looked "real angry" (U.S. Brief 4). Cirrito asked petitioner to step outside because the police suspected he had battered Rojas and wanted to separate the two. Petitioner then yelled "you don't have any right to come in here. I know my rights." The officers then restrained petitioner because of the evidence of domestic violence and escorted him out of the apartment (U.S. Brief 4). A tattoo was spotted at the top of the petitioner's head that matched the descripti on of the man who robbed Lopez. After Cirrito returned to the apartment, he told Rojas that petitioner had been identified as suspect in the robbery and asked for consent to search. Rojas consented both orally and in writing. Officers then searched the apartment and found Drifters gang paraphernalia, a knife that might have been used in the robbery, and a sawed-off shotgun. Petitioner was charged with robbery, infliction of corporal injury on a spouse, cohabitant, or child's parent, possession of a firearm by a felon, possession of a short barreled shotgun, and felony possession of ammunition (U.S.Brief 5). He proceeded to trial on the robbery and infliction of corporal injury counts. He was convicted and sentenced to 14 years of imprisonment. This case reached the U.S. Supreme Court through the writ of certiorari to the California Court of Appeal, second appellate district. This case came on appeal, which was long after Fernandez's trial where he had been found guilty. Petitioner had petitioned to have his case considered by the California Court of Appeals. After he lost there, the Supreme Court granted certiorari to petitioner's case. This was granted because the case involves the fourth amendment, which is in the Constitution, and the Supreme Court want to hear it because of the issue. The U.S has jurisdiction to hear this case because in nearly all of the cases heard by the Supreme Court, the Court exercises the appellate jurisdiction granted it by Article III of the Constitution . This authority permits the Court to review - and affirm or overturn - decisions made by lower courts on Constitutional issues. The legal issue presented in this case is whether the fourth amendment right of the people "being secure

Market Research Apple

Market Research Apple Introduction Findings and discussion Apple Incorporation has over the past few years appreciated the importance of market research. One of the factors that have led to this transformation is the intensity of competition within the PC and mobile device industry. In 2011, Apple Incorporation enjoyed a substantial market share within the iPads segment (Vascellaro, 2012).Advertising We will write a custom essay sample on Market Research Apple specifically for you for only $16.05 $11/page Learn More During this period, iPads were new product in the market. Moreover, competition within this market segment was relatively low. However, this trend has changed significantly. More investors have ventured into the industry in an effort to exploit the growing market opportunity. Currently, Apple’s competitors are increasingly investing in research and development in an effort to gain a substantial market share. The firm faces intense competition from Google Nexus 7 and Microsoft Surface which has led to a decline in Apple’s market share with regard to tablets from 81% to 52%. The high rate at which firm in the PC and mobile device industry are investing in research and development has motivated Apple to continuously develop its products in order to ensure that they are aligned to customers’ tastes and preferences. According to Tassi (2012), market research plays a significant role in developing a company’s competitive strength. Before introducing the new iPad Mini, Apple conducted a market research. The market research was aimed at gathering market information on two main variables, which include the consumer and the competitor. Findings of the market research revealed that the firm’s competitors are increasingly courting their customers in order to determine their next big move. Consequently, Apple will be forced to start courting its customers in order to gain valuable market information (Vascellaro, 2012). The research revealed that there is a high market opportunity for the firm’s products. This is mainly so in emerging markets such as China (Vascellaro, 2012). Chinese customers are amongst the greatest enthusiasts of smart phones. According to Brian White, the smaller iPad will present a substantial growth opportunity for Apple compared to the current iPad. However, the firm will be required to ensure that the product features developed appeal the target customers. Vascellaro (2012) asserts that customers in both developed and developing economies are increasingly being appealed by new smart phone and tablet features.Advertising Looking for essay on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More By analyzing its customer’s feedback, Apple Incorporation revealed that customers increasingly prefer smaller devices for convenience. This is one of the issues that the firm will take into consideration in th e process of designing the iPad Mini. The firm will ensure that the screen of the iPad is approximately 7 to 8 inches long (AppleInsider, 2012). In addition to new features, the likelihood of iPad Mini succeeding upon its introduction in emerging markets such as China is also enhanced by the fact that customers have developed a high level of trust towards Apple’s brand due to its unique design. A study conducted by the firm in seven countries on reasons that motivate customers to select their specific stores in their purchasing process revealed that most customers prefer Apple due to the high level of trust associated with the firm’s products. Fifty four (54%) of the customers interviewed in China and US cited ‘trust Apple brand’ as their core reason for purchasing Apple’s products. On the other hand, 67% of customers interviewed in China cited the products’ design and physical features are their main motivation towards Apple’s product s. This presents a unique market opportunity for Apple to exploit in the course of developing the iPad mini. Adherence to customers’ needs and wants will increase the likelihood of the product gaining sufficient market acceptance upon its introduction Vascellaro (2012). From the market research conducted, Apple Incorporation identified the education sector as one of the new market segment for its iPad Mini. According to Brian White, a renowned market research analyst, there is high probability of iPad Mini succeeding within the education sector. This arises from the fact that educational institutions are increasingly encouraging students to use technology in their learning process. In the course of designing the iPad Mini, Apple appreciates the need to exploit this opportunity. Consequently, the firm will integrate the element of portability. This will play a significant role in increasing the rate of iPad Mini utilization by students. Moreover, the convenience nature of the iPad Mini will stimulate iPad owners in developed economies to purchase the second and smaller model (Hughes, 2012). This will be made possible by the fact that the firm will integrate iCloud technology which will enable iPad users to swap between regular sized iPad and the iPad Mini.Advertising We will write a custom essay sample on Market Research Apple specifically for you for only $16.05 $11/page Learn More In the course of introducing the iPad Mini, Apple’s management team intends to set the price of the product at $ 300 which is relatively high according to most customers (Oliver, 2012). However, the firm projects that the product will gain sufficient market acceptance. This will arise from the fact that the new product features will successfully lure customers to purchase the product. In summary, findings of the market research reveal that there is a high probability of the iPad Mini succeeding upon its introduction in the market. Firstly, the new product features will appeal a large number of potential customers and existing customers in the developed and emerging economies. Additionally, the unique design and usability of the iPad Mini will increase its utilization amongst new customer categories. By ensuring that the new iPad is effectively designed and developed, Apple Incorporation will be able to gain substantial market share within the PC and mobile device industry that has become very competitive.

The Uses and Gratification Theory Case Study Example | Topics and Well Written Essays - 4000 words

The Uses and Gratification Theory - Case Study Example In previous eras, the main sources of entertainment for people tended to be festivals dedicated either to harvesting or in praise of one god or another. In the western perspective, this came to be replaced by theatre and with the modern age came the development of television and the television networks which continue to offer a wide variety of visual entertainment. The advancement in technology has increased the demand for entertainment from individuals, and because of the wide variety of entertainment being offered, it is not a surprise that many of the entertainment companies involved are competing heavily to capture audiences. Because of this, the audience has gained great influence in controlling the type of media they would like to view, and this can be likened to the individual’s lifestyle as well as mindset (Napoli, forthcoming). From the very beginning of the development of media, the main question that has concerned the developers is whether the media has any influenc e on the audience. It has been proven that different types of media can influence the audience, so that in some cases when an individual sees an advert of a product on television, he or she will likely purchase the product. On the other hand, there are those of the view that media has no great influence on its audience since it is they who choose what to watch (Allison, 2006). This article makes a focus on the motives behind the choice of a particular media type as a basis of the Theory of Audience especially uses and Gratification theory. In the past few decades, the invention and development of the internet have revolutionized the lives of many people in the world and one would argue that it is one of the biggest developments in mass media. Every decade of the twentieth century presented its own theories concerning media communication, and while at the beginning, it was thought that media had an effect on the audience, later with the advancement in media communication, researchers found that audiences only used media for their own benefit (Rossi, 2002). Theory of Audience Uses and Gratifications Katz first proposed the theory of Uses and Gratification and the notion behind this theory is, it focuses on a question of why and how people use particular media. In contrast to the effect model view which is what media do with people, U & G is considered as a broader aspect among media researchers who are more concerned about finding what people do with a media (Chandler,1994). This theory is contradictory to the older approach of Audience of a passive group. This theory views the audience as an active group which means individuals have power and selects that media text that best suits her needs and her attempts to satisfy the needs. This theory represents the use of media in terms of gratification of social or psychological need of the individual. This theory shifted the approach of gratification from the functional paradigm to social sciences (Katz, Blumler and G urevitch, 1974).  Gratification can be derived from three distinct sources which are media content, exposure, and social content. The mass media compete with other sources of gratification, but gratifications can be obtained from a medium's content (e.g. watching a specific program), from familiarity with a genre within the medium (e.g. watching soap operas).

Organic solar cells Essay Example | Topics and Well Written Essays - 500 words

Organic solar cells - Essay Example Solar energy is a potential alternative to the production of energy with petroleum. The present solar-cell technology’s energy yield is often not the same and mass-production proves expensive. There is incomplete information of the solar energy production’s total effect on environment. A research team at the Rochester Institute of Technology (RIT) carried out one of the first assessments of the life-cycle of organic solar cells in an attempt to develop a better understanding of the detriments and environmental benefits of solar power. The research was directed at the calculation of total use of energy and impact of material collection, production, fabrication, and use of organic solar cells on the environment by means of a detailed assessment of the technology. As a result of this research, it was found that the total amount of energy needed to make a product is more for the conventional inorganic devices in comparison to the organic solar cells. The assistant professor of chemical engineering, Brian Landi, who has served as a faculty advisor in this research project at RIT says, â€Å"This analysis provides a comprehensive assessment of how much energy it takes to manufacture an organic solar cell, which has a significant impact on both the cost and environmental impact of the technology† (Landi cited in Dube). Organic solar cells are considered to be low-cost as well as potentially benign power sources environmentally. The components of organic solar cells that play the role of absorbing light and taking the charge i.e. Ï€-Conjugated (semiconducting) polymers cannot be made in the laboratories in amenable ways to the manufacturing with low impact on the environment. Organic solar cells are lightweight and flexible. Their tendency to provide the cost effective solution processing generates a range of benefits for manufacturing over the technologies of the

Chapter 2 Literature Review 2.1 History of Solar Water Heating System Throughout human’s history the sun has always been a subject of guess and mystery. In fact, most ancient cultures have considered the sun as a god or godlike due to its life-giving and energy-giving. Thus, the subject of solar is one of the oldest subject for human. Besides that, it has gone through many evolutions and has been the subject of many schools of thought- starting with religion, and ending up in the field of science. It is impossible to exactly date the first uses of solar energy, it maybe the Egyptian, Chinese or even the Malay first invented solar energy. But we do know that ancient Greeks and Romans civilizations, made good use of passive solar energy in their building designs. The use of Solar Water Heating System has a surprisingly long history. Year 1891, Clarence M. Kemp became the first man to patent a Solar Water Heater, called the â€Å"Climax†(Bob Ramlow and Benjamin Nusz, 2006, p.2). It was a black painted water tank mounted in an insulated box with glass on one side. The Climax was instantly popular in California. Thousands of Climaxes and similar systems were installed in a short time. Figure 2. 1 An old advertisement for the Climax Solar Water Heater Year 1909, William J. Bailey, a California Engineer began selling a new system Solar Water Heater named â€Å"Day and Night†(Ramlow and Nusz, 2006, p.3). It consisted of a solar collector and a separate storage tank mounted above the collector. Year 1913, a freak cold snap hit southern California and many â€Å"Day and Night† Solar Water Heater collectors froze and burst. To terminate future freezing problem, Bailey installed a coil of pipe within the storage tank to act as a heat exchanger. Then he used an alcohol and water mixture as the antifreeze solution for his heat exchange medium. This system called as a â€Å"closed-loop† Solar Water Heating System. Year 1979, U.S. President Jimmy Carter made the following prophetic statement at the inauguration of a solar-thermal water heater installed on the White House roof: â€Å"In the Year 2000, the solar heater behind me will still be here, supplying cheap, efficient energy. A generation from now, this solar heater can either be a curiosity, a museum piece, an example of a road not taken; or it can be just a small part of the greatest and most exciting adventure ever undertaken by the American people.† (Ondrey, 2009). 2.2 Introduction of Solar Water Heating System One of the biggest uses of electricity, gas and oil is the heating of water in the home. Solar Water Heating System is a very simple and efficient way to grab energy from sun and use it. Solar Water Heater collects and converts solar radiation energy to useful thermal energy into the form of hot water. It essentially consists of solar collectors for absorbing and converting the solar energy and an insulated storage vessel or tank to contain the heated water. The amount of hot water a solar water heater produces depends on:- type and size of the system amount of sun available at the site seasonal hot water demand pattern and installation of the system Solar Water heater used in the homes for supplying domestic hot water are typically installed with some form of back-up heating system such as electricity to ensure a hot water supply during the night time and cloudy conditions. Solar water heater can be considered as per-heater. The Solar Water Heater raises the temperature of water before it enters the water tank. 2.3 Types of Solar Water Heating System There are two types of Solar Water Heating Systems, either is active or passive. Both of the types are working on the same principles. The only difference is active systems have a pump moving the water through the Solar Water Heating System but passive systems rely on nature principles which is warm water rises to the top, and cold water sinks to the bottom. With a passive Solar Water Heating System, the water storage tank must therefore always be positioned above the solar water heater collector. 2.3.1 Active Solar Water Heating System Active Solar Water Heaters rely on electric pumps, and the controllers to circulate water, or other heat-transfer fluids through the collectors. These are the types of Active Solar Water Heating System:- Open loop active systems- circulate water directly from the tank through the collectors (Morrison, 2005, p.226). This design is efficient and also can lower operating costs if there is no problem with the water supply because of calcium deposits quickly build up in the collector. Closed loop active systems- the heat transfer fluid is pumped through the collectors, and a heat exchanger is used to transfer heat from the collector loop to the water in the tank (Morrison, 2005, p.227). The two most common closed loop active  systems are:- Antifreeze- The heat transfer fluid is usually a glycol-water mixture with the glycol concentration depending on the expected minimum temperature. The glycol is usually food-grade propylene glycol because it is non-toxic. Drainback systems- A type of indirect system, use pump to circulate water through the collectors. The water in the collector loop drains into a reservoir tank when the pumps stop. This makes drainback systems a good choice in colder climates. Drainback systems must be carefully installed to assure that the piping always slopes downward, so that the water will completely drain from the piping. This can be difficult to achieve in some circulation. Active systems are usually more expensive and are less efficient than passive system of antifreeze measures are required. Active systems are more difficult to retrofit in houses that do not have basements because space must be found in house for additional equipment (Morrison, 2005, p.226). 2.3.2 Passive Solar Water Heating System Passive Solar Water Heaters rely on gravity and the tendency for water to naturally circulate as it is heated. Due to they contain no electric components, passive systems are generally more reliable, easier to maintain, and possibly have a longer work life than active systems. The two most popular types of passive systems are:- Integral-collector storage systems- combine tank and collector into one unit. These systems are simple and effective (Morrison, 2005, p.225). This system is only good in households with daytime and evening hot water needs due to high heat loss at night. The main limitation with this system concept is it is only a pre-heater and must be connected in series with a conventional water heater if a 24 hours hot water supply is required. Thermosyphon systems- an economical and reliable choice, especially in new homes. These systems rely on the natural circulation of water between the collector and the tank or heat exchanger (Morrison, 2005, p. 223). The tank set up must above the collector due to achieve circulation during daytime and also to limit reverse circulation at nighttime. Water which is heated will rise naturally into the tank and cooler water flows down to the bottom of the collector, causing circulation throughout system. 2.4 Pros and Cons of Solar Water Heating System 2.4.1 Advantages of Solar Water Heating System Installing a Solar Water Heater is an investment that will save our money for the coming years and it is simple to construct. It is almost free once the equipment is installed because of the â€Å"fuel† for the Solar Water Heater is getting from sun. Energy from the sun is renewable. So, we are protected from electricity bill increment year by year in the future. It is four times cheaper than electricity (Pandey and Banerjee, 1998, p.17). Besides that, it is environment free because it produces no greenhouse gases. Solar Water Heater avoids nitrogen oxides, carbon dioxide, sulphur dioxide and other air pollutants created when electric water heater is used to heat water. Solar Water Heater reduces pollutants and contribute to a healthier environment Other than that, Solar Water Heater is extremely safe and clean. We will feel free from the problem which will occur by electric water heater because Solar Water Heater mostly no maintenance, repair work or cleaning is required. By choosing a Solar Water Heater to heat water in home, it is an intelligent, socially aware and environmentally responsible energy source. 2.4.2 Disadvantages of Solar Water Heating System Although Solar Water Heating System consists of a lot of advantages, but it has its disadvantages also. First of all, Solar Water Heater will doesn’t work well on days when it is cloudy, over cast or raining. Besides that, it doesn’t work at nighttime. So, it is typically installed with electric water heater to ensure that hot water is supplied when the day is cloudy, overcast, raining or at night. Other than that, Cost of purchase Solar Water Heater is one the most critical issue. The initial cost of Solar Water Heater is high for Malaysian if compare to electric water heater. Many of the residents will not choose Solar Water heater due to its high initial cost. In addition, appearance of the house will affected due to the collector of Solar Water Heater is being installed on the roof. 2.5 Selecting a Solar Water Heater Before purchasing and installing a Solar Water Heating System, we are required to do the following:-  ·Ã‚  Consider into the economics of a Solar Water Heating System  ·Ã‚  Consider into the needs of hot water required  ·Ã‚  Determine the correct size for Solar Water Heating System  ·Ã‚  Determine the energy efficiency of Solar Water Heating System  ·Ã‚  Estimate and compare system costs 2.6 Method of Installation for Solar Water Heating System The installation of a Solar Water Heater requires skills that overlap many trades. Installer needs to be familiar with plumbing, roofing and electrical. Here will shows the various steps and processes to install a Solar Water Heater. This Solar Water Heating System consists of flat-plate collector, a differential controller, several sensors, a pump, and various valves. Step 1: Collector Mounting Before start the installation, installer must verify that the roof is suitable for the condition of mounting of the solar collector. Installer has to ensure that the roof tiles are in satisfactory condition and the trusses are adequate to support the collector. In general, there is no problem for installing a solar collector on a traditional roof. Besides that, it is recommended that the solar collector to face to south or within 30 º to 45  º east or west of due south. The installer needs to locate the trusses that will be use to attach the solar mounting brackets. After installer locates the trusses, he will then makes preparation for the installing of the collector mounting clips. The collector will then attach to the clips. Installer will carefully remove the roof tiles where the mounting clips will be installed. Four mounting clips will be used to support the collector and also to distribute the weight at the four mounting locations. Lastly, solar collector installs on the mounting clips. Step 2: Roof Pipe Flashing First of all, installer needs to identify and mark down the locations of the piping penetrations. There will be two penetration-collector feed line and collector return line. In gravity drain system, the feed line should penetrate the roof below the collector. Then, make a flat copper flashing with an oversize collar to penetrate the fluid line. Step 3: Piping from Tank to Collector Installer will install the pipe that will connect the water heater to the solar connector. Normally, soft copper will be used in the attic run between the tank area components and the collector lines exits at the roof because by using soft copper, installer does not have to solder any fittings in the attic. Pipe hangers will be used in locations to secure the long piping runs. Besides that, insulation will be installed on all attic piping to prevent heat loss. Step 4: Collector Feed line Piping Installer will measure, cut and fit the pipe fittings for proper length. He will solder the piping and fittings once all of them have been attached correctly. Step 5: Collector Return Line Plumbing Installer will solder fittings that will accommodate the system air vent. The system can prevent air locks that will restrict flow in the system. Air vent is always install at the high point of system and in a true north vertical position. Then, installer will solder more fitting such as pressure relief valve. Step 6: Storage Tank Installer starts the installation for storage tank. this involves plumbing the water heater for cold service, hot outlet, collector feed and return lines. Installer will place insulation on all exposed piping once the piping has been installed to reduce heat loss during system operation. Lastly, he will set the thermostat on the water heater because although the majority of the how water is produced by solar energy, but when cloudy, overcast or nighttime, the electric elements are always the spare for it. Step 7: Controller and Sensors Installer will install controller and sensor for the system. The differential controller is the brains of solar system. It works with two sensors. One of it located at the hottest part of the system which is collector outlet. The other one is located at the coldest part of the system which is the bottom of the tank. Step 8: Pump and Valves A Solar Water Heating System consists of a variety of components. System pump also called as circulator is a critical component for Solar Water Heating System. Its function is to circulate the fluid from the tank to the collector. Then the fluid gains heat in the solar collector and return to the storage tank. Besides that, check valve, drain valves and isolation valves also the components to install. Step 9: Pipe Insulation The last step for installation process is pipe insulation. It is to prevent heat loss from the piping, so pipe insulation is installed on both external and internal system piping. After that, installer should provide the owner of the Solar Water Heater a system operation and maintenance manual. 2.7 A Comparison between Solar Water Heater and Electric Water Heater Solartech (Summer) CX – Direct Heating* Panasonic DH – 3HE1M** Panasonic DH – 3HT1M** Type of Water Heater Solar Electric Electric Power Consumption 2.4 KW (back up heating element) 3.6 KW 3.6 KW Selling Price / unit RM 5,490.00 RM 639.00 RM 449.00 Selling Price (2 units) RM 1,278 RM 1,098 Initial Cost (selling price + installation cost) RM 5,690.00 RM 1428.00 RM 1248.00 Warranty (full warranty) 10 years 1 year 1 year Operation Cost / year RM 170.25 RM 1,109.67 RM 1,109.67 Operation Cost (10 years) RM 1702.50 RM 11,096.70 RM 11,096.70 Total Cost (initial cost + operation cost) for 10 years without maintenance cost RM 7,392.50 RM 12,374.70 RM 12,194.70 Environment Impact free CO2 CO2 Table 2. 1 Comparison between Solar Water Heater and Electric Water Heater * Description is given by Solartech Sales Service Sdn Bhd ** Description is given by Pansasonic Malaysia Sdn Bhd The table above shows the comparison between Solar Water Heater and Electric Water Heater.

Chapter 2 Literature Review 2.1 History of Solar Water Heating System Throughout human’s history the sun has always been a subject of guess and mystery. In fact, most ancient cultures have considered the sun as a god or godlike due to its life-giving and energy-giving. Thus, the subject of solar is one of the oldest subject for human. Besides that, it has gone through many evolutions and has been the subject of many schools of thought- starting with religion, and ending up in the field of science. It is impossible to exactly date the first uses of solar energy, it maybe the Egyptian, Chinese or even the Malay first invented solar energy. But we do know that ancient Greeks and Romans civilizations, made good use of passive solar energy in their building designs. The use of Solar Water Heating System has a surprisingly long history. Year 1891, Clarence M. Kemp became the first man to patent a Solar Water Heater, called the â€Å"Climax†(Bob Ramlow and Benjamin Nusz, 2006, p.2). It was a black painted water tank mounted in an insulated box with glass on one side. The Climax was instantly popular in California. Thousands of Climaxes and similar systems were installed in a short time. Figure 2. 1 An old advertisement for the Climax Solar Water Heater Year 1909, William J. Bailey, a California Engineer began selling a new system Solar Water Heater named â€Å"Day and Night†(Ramlow and Nusz, 2006, p.3). It consisted of a solar collector and a separate storage tank mounted above the collector. Year 1913, a freak cold snap hit southern California and many â€Å"Day and Night† Solar Water Heater collectors froze and burst. To terminate future freezing problem, Bailey installed a coil of pipe within the storage tank to act as a heat exchanger. Then he used an alcohol and water mixture as the antifreeze solution for his heat exchange medium. This system called as a â€Å"closed-loop† Solar Water Heating System. Year 1979, U.S. President Jimmy Carter made the following prophetic statement at the inauguration of a solar-thermal water heater installed on the White House roof: â€Å"In the Year 2000, the solar heater behind me will still be here, supplying cheap, efficient energy. A generation from now, this solar heater can either be a curiosity, a museum piece, an example of a road not taken; or it can be just a small part of the greatest and most exciting adventure ever undertaken by the American people.† (Ondrey, 2009). 2.2 Introduction of Solar Water Heating System One of the biggest uses of electricity, gas and oil is the heating of water in the home. Solar Water Heating System is a very simple and efficient way to grab energy from sun and use it. Solar Water Heater collects and converts solar radiation energy to useful thermal energy into the form of hot water. It essentially consists of solar collectors for absorbing and converting the solar energy and an insulated storage vessel or tank to contain the heated water. The amount of hot water a solar water heater produces depends on:- type and size of the system amount of sun available at the site seasonal hot water demand pattern and installation of the system Solar Water heater used in the homes for supplying domestic hot water are typically installed with some form of back-up heating system such as electricity to ensure a hot water supply during the night time and cloudy conditions. Solar water heater can be considered as per-heater. The Solar Water Heater raises the temperature of water before it enters the water tank. 2.3 Types of Solar Water Heating System There are two types of Solar Water Heating Systems, either is active or passive. Both of the types are working on the same principles. The only difference is active systems have a pump moving the water through the Solar Water Heating System but passive systems rely on nature principles which is warm water rises to the top, and cold water sinks to the bottom. With a passive Solar Water Heating System, the water storage tank must therefore always be positioned above the solar water heater collector. 2.3.1 Active Solar Water Heating System Active Solar Water Heaters rely on electric pumps, and the controllers to circulate water, or other heat-transfer fluids through the collectors. These are the types of Active Solar Water Heating System:- Open loop active systems- circulate water directly from the tank through the collectors (Morrison, 2005, p.226). This design is efficient and also can lower operating costs if there is no problem with the water supply because of calcium deposits quickly build up in the collector. Closed loop active systems- the heat transfer fluid is pumped through the collectors, and a heat exchanger is used to transfer heat from the collector loop to the water in the tank (Morrison, 2005, p.227). The two most common closed loop active  systems are:- Antifreeze- The heat transfer fluid is usually a glycol-water mixture with the glycol concentration depending on the expected minimum temperature. The glycol is usually food-grade propylene glycol because it is non-toxic. Drainback systems- A type of indirect system, use pump to circulate water through the collectors. The water in the collector loop drains into a reservoir tank when the pumps stop. This makes drainback systems a good choice in colder climates. Drainback systems must be carefully installed to assure that the piping always slopes downward, so that the water will completely drain from the piping. This can be difficult to achieve in some circulation. Active systems are usually more expensive and are less efficient than passive system of antifreeze measures are required. Active systems are more difficult to retrofit in houses that do not have basements because space must be found in house for additional equipment (Morrison, 2005, p.226). 2.3.2 Passive Solar Water Heating System Passive Solar Water Heaters rely on gravity and the tendency for water to naturally circulate as it is heated. Due to they contain no electric components, passive systems are generally more reliable, easier to maintain, and possibly have a longer work life than active systems. The two most popular types of passive systems are:- Integral-collector storage systems- combine tank and collector into one unit. These systems are simple and effective (Morrison, 2005, p.225). This system is only good in households with daytime and evening hot water needs due to high heat loss at night. The main limitation with this system concept is it is only a pre-heater and must be connected in series with a conventional water heater if a 24 hours hot water supply is required. Thermosyphon systems- an economical and reliable choice, especially in new homes. These systems rely on the natural circulation of water between the collector and the tank or heat exchanger (Morrison, 2005, p. 223). The tank set up must above the collector due to achieve circulation during daytime and also to limit reverse circulation at nighttime. Water which is heated will rise naturally into the tank and cooler water flows down to the bottom of the collector, causing circulation throughout system. 2.4 Pros and Cons of Solar Water Heating System 2.4.1 Advantages of Solar Water Heating System Installing a Solar Water Heater is an investment that will save our money for the coming years and it is simple to construct. It is almost free once the equipment is installed because of the â€Å"fuel† for the Solar Water Heater is getting from sun. Energy from the sun is renewable. So, we are protected from electricity bill increment year by year in the future. It is four times cheaper than electricity (Pandey and Banerjee, 1998, p.17). Besides that, it is environment free because it produces no greenhouse gases. Solar Water Heater avoids nitrogen oxides, carbon dioxide, sulphur dioxide and other air pollutants created when electric water heater is used to heat water. Solar Water Heater reduces pollutants and contribute to a healthier environment Other than that, Solar Water Heater is extremely safe and clean. We will feel free from the problem which will occur by electric water heater because Solar Water Heater mostly no maintenance, repair work or cleaning is required. By choosing a Solar Water Heater to heat water in home, it is an intelligent, socially aware and environmentally responsible energy source. 2.4.2 Disadvantages of Solar Water Heating System Although Solar Water Heating System consists of a lot of advantages, but it has its disadvantages also. First of all, Solar Water Heater will doesn’t work well on days when it is cloudy, over cast or raining. Besides that, it doesn’t work at nighttime. So, it is typically installed with electric water heater to ensure that hot water is supplied when the day is cloudy, overcast, raining or at night. Other than that, Cost of purchase Solar Water Heater is one the most critical issue. The initial cost of Solar Water Heater is high for Malaysian if compare to electric water heater. Many of the residents will not choose Solar Water heater due to its high initial cost. In addition, appearance of the house will affected due to the collector of Solar Water Heater is being installed on the roof. 2.5 Selecting a Solar Water Heater Before purchasing and installing a Solar Water Heating System, we are required to do the following:-  ·Ã‚  Consider into the economics of a Solar Water Heating System  ·Ã‚  Consider into the needs of hot water required  ·Ã‚  Determine the correct size for Solar Water Heating System  ·Ã‚  Determine the energy efficiency of Solar Water Heating System  ·Ã‚  Estimate and compare system costs 2.6 Method of Installation for Solar Water Heating System The installation of a Solar Water Heater requires skills that overlap many trades. Installer needs to be familiar with plumbing, roofing and electrical. Here will shows the various steps and processes to install a Solar Water Heater. This Solar Water Heating System consists of flat-plate collector, a differential controller, several sensors, a pump, and various valves. Step 1: Collector Mounting Before start the installation, installer must verify that the roof is suitable for the condition of mounting of the solar collector. Installer has to ensure that the roof tiles are in satisfactory condition and the trusses are adequate to support the collector. In general, there is no problem for installing a solar collector on a traditional roof. Besides that, it is recommended that the solar collector to face to south or within 30 º to 45  º east or west of due south. The installer needs to locate the trusses that will be use to attach the solar mounting brackets. After installer locates the trusses, he will then makes preparation for the installing of the collector mounting clips. The collector will then attach to the clips. Installer will carefully remove the roof tiles where the mounting clips will be installed. Four mounting clips will be used to support the collector and also to distribute the weight at the four mounting locations. Lastly, solar collector installs on the mounting clips. Step 2: Roof Pipe Flashing First of all, installer needs to identify and mark down the locations of the piping penetrations. There will be two penetration-collector feed line and collector return line. In gravity drain system, the feed line should penetrate the roof below the collector. Then, make a flat copper flashing with an oversize collar to penetrate the fluid line. Step 3: Piping from Tank to Collector Installer will install the pipe that will connect the water heater to the solar connector. Normally, soft copper will be used in the attic run between the tank area components and the collector lines exits at the roof because by using soft copper, installer does not have to solder any fittings in the attic. Pipe hangers will be used in locations to secure the long piping runs. Besides that, insulation will be installed on all attic piping to prevent heat loss. Step 4: Collector Feed line Piping Installer will measure, cut and fit the pipe fittings for proper length. He will solder the piping and fittings once all of them have been attached correctly. Step 5: Collector Return Line Plumbing Installer will solder fittings that will accommodate the system air vent. The system can prevent air locks that will restrict flow in the system. Air vent is always install at the high point of system and in a true north vertical position. Then, installer will solder more fitting such as pressure relief valve. Step 6: Storage Tank Installer starts the installation for storage tank. this involves plumbing the water heater for cold service, hot outlet, collector feed and return lines. Installer will place insulation on all exposed piping once the piping has been installed to reduce heat loss during system operation. Lastly, he will set the thermostat on the water heater because although the majority of the how water is produced by solar energy, but when cloudy, overcast or nighttime, the electric elements are always the spare for it. Step 7: Controller and Sensors Installer will install controller and sensor for the system. The differential controller is the brains of solar system. It works with two sensors. One of it located at the hottest part of the system which is collector outlet. The other one is located at the coldest part of the system which is the bottom of the tank. Step 8: Pump and Valves A Solar Water Heating System consists of a variety of components. System pump also called as circulator is a critical component for Solar Water Heating System. Its function is to circulate the fluid from the tank to the collector. Then the fluid gains heat in the solar collector and return to the storage tank. Besides that, check valve, drain valves and isolation valves also the components to install. Step 9: Pipe Insulation The last step for installation process is pipe insulation. It is to prevent heat loss from the piping, so pipe insulation is installed on both external and internal system piping. After that, installer should provide the owner of the Solar Water Heater a system operation and maintenance manual. 2.7 A Comparison between Solar Water Heater and Electric Water Heater Solartech (Summer) CX – Direct Heating* Panasonic DH – 3HE1M** Panasonic DH – 3HT1M** Type of Water Heater Solar Electric Electric Power Consumption 2.4 KW (back up heating element) 3.6 KW 3.6 KW Selling Price / unit RM 5,490.00 RM 639.00 RM 449.00 Selling Price (2 units) RM 1,278 RM 1,098 Initial Cost (selling price + installation cost) RM 5,690.00 RM 1428.00 RM 1248.00 Warranty (full warranty) 10 years 1 year 1 year Operation Cost / year RM 170.25 RM 1,109.67 RM 1,109.67 Operation Cost (10 years) RM 1702.50 RM 11,096.70 RM 11,096.70 Total Cost (initial cost + operation cost) for 10 years without maintenance cost RM 7,392.50 RM 12,374.70 RM 12,194.70 Environment Impact free CO2 CO2 Table 2. 1 Comparison between Solar Water Heater and Electric Water Heater * Description is given by Solartech Sales Service Sdn Bhd ** Description is given by Pansasonic Malaysia Sdn Bhd The table above shows the comparison between Solar Water Heater and Electric Water Heater.

It should be done before August 01, 2009, but in stead it was done on August 22, 2009. The reason for the delay because of Introduction is revised proposal, so I decided to postpone it until the same with the date of completion for literature review. For Literature Review, I started it a week earlier than the proposed work schedule due to I need longer time to search information from TARC library and internet. Besides that, I also needed to get the quotation from supplier so that I started my literature review earlier. Luckily, everything in progress and I finished my literature review on time. My supervisor, Mr. Teh Bin Sin checked my works on August 20, 2009 and I printed out all the chapters for interim submission.

July 26, 2009 – August 01, 2009 Objectives ‘To compare the initial cost, price, durability, maintenance cost and environment impact for solar water heating system and electric water heater’ changed to ‘To compare the initial cost, price, durability, and environment impact for solar water heating system and electric water heater’ Due to the comment from supplier, which is maintenance cost is difficult to calculate or estimate for the following 10 years for water heater, so I decided to take out the comparison of maintenance cost in objective.

A D-train Passenger Views Outside :: Land Beauty Essays

A D-train Passenger Views Outside The passenger realizes as the light of the sunset passes through the gaps in the skyscrapers that what he sees is good. The glittering reddish sky slowly disappears as the clouds fly; the train descends as the view passes by into the darkness of the underground. It is a scene most of us will encounter if we ever take the New York subway over the Manhattan Bridge at sunset. Many times I have seen this panorama, but it still does not fail to capture me, to draw me away from my book, and to the window. Then while the bridge-columns flash by the windows, in the gaps, like an old movie, the view unrolls in all its beauty. How did our ancient ancestors feel when they saw this spectacular sight? (I mean the â€Å"ancient† of a few decades ago.) I really can’t tell you, because I never was an ancient, and if I saw one, that is not one of the topics that we discussed. But I can tell you how a very intelligent modern man thinks of it. (That would be me. I am also very humble.) I feel that it is a wondrous sight, if you think about it. But only if you think about it. A being less cultured, in a specific way, would not regard the sight as beautiful, inspiring, wondrous, exalting or stupefying. He probably would not even know if those word s exist. He would probably say that it is, well, big. To him it is not necessarily beautiful. We can only understand that it must be beautiful since so much work was put into it, so many people contributed to it and built it, so many breakthroughs had to be achieved prior to the conception, that this site is the culmination of the millennia of human history and science that came before it. Now isn’t that inspiring? (It sure sounds inspiring if you ask me. It even has some pretty long words, so it better be inspiring.) I look at the unfolding view and, subliminally, I think of all the things mentioned above, and only then do I consider the view beautiful. The aforementioned â€Å"uncultured† being looks at it, and finds it â€Å"big†. In his essay â€Å"A First American Views His Land†, N. Scott Momaday tried to express the beauty of that land that he lived in, and the feelings he personally, and Native Americans in general, had toward that land.

Prose †A Christmas Carol Essay

But it’s too late now’, showing either that he is not as bitter as we thought, or that he is already learning from the lessons he is being taught. He is also deeply affected in the third episode when talking to the Spectre about his late sister and her son; Fred, his nephew. After we see his reaction, which was filled with sorrow and remorse, we realise that a possible reason for his hatred of Christmas is because of the death of his sister, and the reason for Scrooge being so mean. Scrooge learns his lesson throughout the novel through the reactions he portrays through the episodes he sees. An important episode in this stave is the one of Scrooge at Mr. Fezziwig’s ball. This is because of the quote ‘He corroborated everything, remembered everything, enjoyed everything’, which is important because it shows that he can love and can, if he wants to, change. Also in this episode, Scrooge says ‘The happiness he gives, is quite as great as if it cost a fortune’, which shows that Scrooge can still love, yet the positives are outweighed by the negatives in his life, so he does not see the point of loving and living. He also says ‘I should like to be able to say a word or two to my clerk just now’, which shows that he is getting the message and is learning the lesson that the Spirits have to give. The next strong reaction that the Ghost gets from Scrooge is after the scene with his fianci , which contains the evident emotions of sadness and regret. His may be for not changing his ways, or for the actions of his fianci , but they are portrayed when he says to the Spirit ‘Why do you delight to torture me? ‘ Lastly, Scrooge tries to extinguish the light upon the Spirit’s head, which is an obvious display of misery and pain which is evoked onto Scrooge in the various scenes. The vivid description of the Ghost at the beginning of the stave is symbolic, like the description of Marley’s chain in the first stave entitled ‘Marley’s Ghost’. The Spirit is described as ‘like a child: yet not so like a child as an old man’, which makes the Ghost seem innocent and good, the common perception a children. The Spectre also has ‘pure white’ clothing, which reinforces innocence, and holds a clove of holly, which symbolises Christianity, and purity also. Other vivid elements of the Spirit’s description include; a crown symbolising a halo which creates an obvious link to heaven and virtue, and ‘a great extinguisher for a cap, which it now held under its arm’, which emphasises its appearance as a ghost. Stave Three is entitled ‘The Second of the Three Spirits’, and at the beginning of which, Dickens creates an apprehensious, and suspenseful atmosphere through the use of the delayed visit from the second Spectre. Unlike the previous two times, pathetic fallery is not used, but, like the last time, the use of time is; ‘five minutes, ten minutes, a quarter of an hour went by, yet nothing came’. This creates suspense as to what will happen, and when the spirit will come. Dickens also sets the scene by having Scrooge on guard, ready for when the next spectre will come, and ready for the same greeting as from the spirit before. This is evident through the quote ‘But, finding that he turned uncomfortably cold when he began to wonder which of the curtains this new spectre would draw back, he put every one aside with his own hands’. This creates suspense because, when the Ghost doesn’t seem to come on time, both the reader and Scrooge begin to wonder if, how and when he will come. This suspenseful atmosphere is enhanced by ‘a strange voice’ calling Scrooge by his name. At this point, we do not know who or what it is, or even if it is the second of the three spirits, which builds up on the suspenseful atmosphere, because of the unknown. The Ghost of Christmas Present shows Scrooge many things about, and to do with Christmas, and mainly shows him why people celebrate it, despite what conditions they live in. Firstly, the Ghost shows Scrooge the market place in the run-up to the present Christmas, with all of the food displays, the frenzied shopping and the excitement of Christmas, all of these things that Scrooge doesn’t do currently, or wouldn’t do without the lessons from the Ghosts, in the run-up to Christmas. This also says the fact that happiness does not come from the amount of money you have, but is through being with loved ones, and making an effort to please and enjoy. This is evident through the quote ‘but the customers were all so hurried and so eager in the hopeful promise of the day’, which describes the enthusiasm of everyone for that one day of the year which is the time for festiveness and family. The Ghost next takes Scrooge to the house of his employee; Bob Cratchitt and family, and sees how the family survive at Christmas, which is pitiful in itself, never mind how they survive normally. The quote ‘Such a bustle ensued that you might have thought a goose was the rarest of birds †¦ ; and in truth it was something like it in this very house’, illustrates how poor the Cratchitts are, for the goose is essentially ordinary, yet is extravagant in this house because they are used to so much less. Yet, this episode shows Scrooge and the reader that Christmas is not just to be celebrated because it is the birth of Jesus, or because it brings many gifts, but because it brings family together and lets people be happy and merry. Collectively, the first two episodes displays to Scrooge that Christmas is not about the bad times in the past, but is about family. Next, Scrooge visits the sailors, miners and lighthouse keepers at Christmas, which describes families and co-workers enjoying each others company, weather young or old, and celebrating Christmas in the ‘bowels of the earth’ and various other conditions, which is more than what Scrooge has ever done, even if his experiences have been the lesser of two evils. These episodes show Scrooge that happiness is not just about money, or is even to do with money, bit is within each other and within family. After that, the Spectre takes Scrooge to his nephew, Fred, celebrating Christmas with his wife and sisters-in-laws. Scrooge sees Fred’s ‘infectious’ laughter which lightens the mood of everyone there, showing that happiness is in others, but he also sees the ridicule they use against him. However, he also sees how much his nephew cares for him, when he says ‘his offences carry their own punishment, and I have nothing to say against him’. When Scrooge goes to see the miners, sailors and the lighthouse keeper, Scrooge learns an important lesson which will help him complete his journey with the three spirits. The lesson is reinforcing to Scrooge, and the reader, that happiness is in others, not in the amount of money one has. This is evident when describing the miners who, according to the spirit, ‘labour in the bowels of the earth’. Dickens describes the families with examples like ‘An old, old man and woman, with their children and their children’s children, and another generation beyond that, all decked out in their holiday attire’, which links to the poor, and their stereotypical big families, and this quote describes how closely linked and happy they are to be with each other, showing that, though they are poor, they are happy. This is also supported by the lighthouse keepers when Dickens says ‘Joining their horny hands over the rough table at which they sat, they whished each other a merry Christmas in their can of grog’. This quote also says that, despite how well off you are or where you live, you can be happy, which is the inevitable lesson Scrooge will learn. The lesson is also taught with the sailors with the quotation ‘and had remembered those he cared for at a distance, and had known that they delighted to remember him’. Scrooge also makes a realisation at his nephew’s house, when he hears what his family really think about him, and also sees how Christmas can be a happy occasion. Firstly, upon entering the house with the Spectre, Scrooge sees his nephew and other family after they have eaten their Christmas dinner, and enjoying the celebrations, which includes music and games like ‘blind-man’s buff’ and ‘yes and no’, the latter of which provided the main source of name-calling directed at Scrooge. However, upon entering, he initially hears a conversation on how it appears that only Fred takes pity on Scrooge, while his companions take delight in mocking him, with jokes about how rich he is and comments about their dislike for him, which contradicts from Fred’s view on Scrooge, like how ‘his offences carry their own punishment’, how he has nothing to say against him, and how ‘His wealth is no good to him. He don’t do any good with it’. After that, the family then goes onto play music, which reminds Scrooge of his days at boarding school, and also the Ghost of Christmas Past and the lessons that he had been shown so far, which adds to the morals he is learning because ‘he might have cultivated the kindness of life for his own happiness with his own hands, without resorting to the sexton’s spade that buried Jacob Marley’, which shows that Scrooge is learning to regret, and see what he has done wrong. Games then follow the music, and in them, happiness is reinforced, again, in others and not in money, through Topper playing ‘blind-man’s buff’ with Fred’s wife’s sister. However, when reaching the last game, Scrooge becomes the target of ridicule, even by Fred, by describing a ‘disagreeable animal, a savage animal, an animal that growled and grunted sometimes, and talked sometimes, and lived in London, and walked about the streets, and wasn’t made a show of, and wasn’t led by anybody, and didn’t live in a menagerie, and was never killed in a market, and was not a horse, or an ass, or a cow, or a bull, or a tiger, or a dog, or a pig, or a cat, or a bear’. The answer was indeed Scrooge, and shows how other people perceive him, even his own family. A major part in the lessons Scrooge learns come from the visit to the Cratchitts’, and he is deeply affected by it. Firstly, Scrooge sees how much, or most suitably how little, the poor, namely the Cratchitts in this episode, get to eat. This is evidently a contrast to what Scrooge would be used to, and would have affected him to see how different the conditions were for the poor. Also when Scrooge visits the Cratchitts, we are introduced to the character Tiny Tim, Bob Cratchitt’s disabled son, who is used in the novel as a symbol of the poor from Victorian England. Dickens uses Tiny Tim to evoke sympathy in both the reader and Scrooge, because of his disability and his poor living conditions, and also because of his good nature towards his life, and the sufferings of other people, showing that he is not selfish despite his condition. Also, Scrooge is affected by his visit to the Cratchitt’s because they seem to be a contradiction of how the poor were seen in typical Victorian times. They were mainly seen as feckless, immoral, idle and drunken, yet Tiny Tim and family are portrayed as loving, caring, moral people, which is another reason why both Scrooge and the reader react so strongly to this episode. When answering Scrooge’s question on whether Tiny Tim will live, the Ghost answers with a quote that Scrooge had said to the charity workers at the beginning of the novel; ‘decrease the surplus population’. This is teaching and reinforcing to Scrooge that his actions were not only wrong, but regrettable, especially after viewing the scene with Bob Cratchitt, Tiny Tim and their family. This also creates a greater impact on Scrooge because he knows they were his own, spiteful words, and shocks him into thinking he could ever say that. This also proves that he is learning the lessons of the Ghosts. When answering Scrooge, the Spirit also uses the line; ‘to hear the Insect on the leaf pronouncing on the too much life among his hungry brothers in the dust’. This line is a metaphor portraying Scrooge as an insect and the dust as the poor and hungry, like Tiny Tim, and reinforcing what Scrooge said earlier, about ‘decreasing the surplus population’. This says that the population is too big and that many should die to reduce it, which is something that Scrooge now regrets saying, so has a bigger impact on his reactions to the Spectre’s answer. At the end of the third stave, the Ghost of Christmas Present shows Scrooge two creatures from under his cloak. They were shaped as children, a boy and a girl, who were described as ‘wretched, abject, frightful, hideous, miserable’.

Chemistry Flame Test Lab Report Essay Example

Chemistry Flame Test Lab Report Essay Example Chemistry Flame Test Lab Report Paper Chemistry Flame Test Lab Report Paper Test Lab was an experiment designed to show how elements react when heated. This Lab attempted to prove that when electrons are excited and then calm, they emit a color specific to the element. This test showed that there is a direct coloration between the heat energy being expelled and the movement of electrons from one energy level to the next. When the atoms of a gas are excited, in this case by heating, their electrons are able to move from their ground states to higher energy levels. The electrons that move are considered excited. As they return to their ground state, the electron emits energy. The energy emitted corresponds to a particular wavelength, and therefore produces a particular color of light. If a excited electron drops one energy level, Its color will be red. If it drops 2 energy levels, it will be orange yellow. 3 energy levels produces greenish blue light and 4 dropped energy levels produce violet light. The amount of energy levels electrons move up after being heated relates to the color of light it produces.

The Medicare essayEssay Writing Service

The Medicare essayEssay Writing Service The Medicare essay The Medicare essayToday, Medicare is the major government-sponsored health care program aiming at the assistance provided for older people in need, who cannot afford covering health care services on their own. The program focuses on the coverage of health care services for older people and is an important source of support of the older people, who live in poverty and cannot earn to cover their health care services. However, today, the effectiveness of Medicare is still under a question since the program needs consistent changes to make the use of public funds more effective and provide all older people in need with health care services of the high quality.In this regard, the improvement of the Medicare should involve systematic changes to optimize the performance of the program. To put it more precisely, the government should avoid overlapping functions of Medicare and other health care programs, such as Medicaid, for example. Medicare should focus on the specific target population a nd avoid ineffective use of funds through distributing public funds for multiple clients and services. The focus on the narrower and more specific target population will help to spend more funds on specific services that will help to provide them with health care services of the high quality.In addition, the population enrolled in Medicare can improve its position through the involvement of non-government organizations in the management of Medicare program. The involvement of non-government organizations will help to decrease the bureaucratization of Medicare which emerges because any government agency tends to bureaucratization without the effective public control.Finally, Medicare should focus on specific health care suppliers, which can provide health care services of the high quality at affordable prices.

Online market Essay Example | Topics and Well Written Essays - 2000 words

Online market - Essay Example It is estimated that $1,900 worth of goods are traded per second worldwide from the eBay platform. eBay auctions are the online version of traditional auctions. The marketplace provides online commerce platforms to buyers and sellers, providing individuals and businesses from around the world the opportunity to interact and trade online. Buying and selling takes place in a variety of ways on eBay. On the auction platform, sellers establish a starting price for a good or service they want to sell. Using the bidding format the interested buyers bid higher prices till the end of the auction after which the seller sells to the highest bidders. Another option available for individuals is the fixed price option called Buy It Now. In this case a fixed price is established by the seller, and the sale is made to the first person who offers to pay the fixed price. The website also offers a Want It Now feature, which allows interested buyers to create a wish list of the things they want to buy, based on which interested sellers can contact them and arrange transactions. Any item can be sold online as long as it is not illegal or does not violate eBay’s Prohibited and Restricted Items policy. eBay generates revenue by charging various fees for its service. The auction service charges the seller per listing and a percentage of the final sale price. E-marketing is the heart of e-business. It involves getting close to customers, adding value to products, expanding distribution channels and increasing sales and offering after sales services (Chaffey & Smith, 2005). According to Ellis and Korper (2001) e-commerce companies just like all others face the challenge of having to define themselves in the global market. Through marketing and branding they need to identify what makes them unique and how this unique selling point can be used to attract customers. Ellis and Korper (2001) explain that the aim of marketing online businesses is to attract customers, get them to

Should gays & lesbians be allowed to serve in the U.S. military Research Paper

Should gays & lesbians be allowed to serve in the U.S. military - Research Paper Example Homosexuals need to be allowed the same opportunities as other people. Their sexual orientation does not make them lesser beings, and it should not be used as an excuse to bar them from doing things that they want to do (Carter 233). I support the idea of having gays and lesbians in the US military, regardless of whether they practice homosexuality or not. I do not see how why this group of well-meaning citizens should be judged for their sexual orientation and yet they are willing to risk their lives for the sake of this great country. For someone to sacrifice his life for the sake of his country and country folk, it requires a remarkable sense of bravery (Bourg 429). Instead of being viewed as unwanted people, gay men and lesbians wanting to join the military should be treated like the heroes they are. The introduction of the â€Å"don’t ask, don’t tell† policy has greatly improved matters for the gay and lesbian community in America (Carter 233). Homosexuals a re no longer required to disclose their sexuality on the enlistment forms. The policy also disallowed any military official investigating the sexual orientation of military officers. This gave homosexuals more freedom and confidence in applying for military positions. No one should be harassed just because they have a different sexual orientation from others. ... If one is to be discriminated against because of something that he or she cannot change, then that is very unfortunate because it would be tantamount to denying them their fundamental rights as citizens of America (Bourg 430). Being different should not be viewed as a weakness or as a moral wrong, rather society should embrace everyone since we all have something positive to share with others. Tolerating and accepting the gay and lesbian community may be a tall order for some people, but this should not be the case. Many gay men and lesbian women have served this country in different aspects with honor (Carter 234). When people say that homosexuals should not serve in the military, what they are portraying is fear about things that might never happen in the first place. This fear is unwarranted because it is obvious that homosexuals live very peacefully with other people, it would not be different in the military. The standard that needs to be upheld in the military is not gender ori entation; rather a lot of emphasis should be on attitude and behavior (Johnson 133). If the gays and lesbians have the right kind of attitude and behavior for military service, then there should be no problem enlisting them. There is no evidence showing that one’s sexuality may determine one’s efficiency at work. The only thing that comes in the way of efficiency is one’s determination or the lack of it. If a homosexual is therefore determined to keep the United States and the citizens safe, I think that he or she should be given the chance. If gays and lesbians are barred from military service, then what is to be said of their fundamental rights and liberties as Americans? The American constitution is categorical in the provision of equality in
