SWOT Analysis Swatch Group

SWOT Analysis Swatch Group Strength In 2010, the Swatch Group has managed to introduce $ 10 billion of sales through presentation of 19 brands meeting the demands of the established market segments (Deshpander et al. 3). In addition, the company’s success was due to the revival of famous brand Omega confronting Rolex. Finally, introducing advanced Co-Axial technologies has allowed the company to sustain a competitive advantage successfully.Advertising We will write a custom case study sample on SWOT Analysis Swatch Group specifically for you for only $16.05 $11/page Learn More Weakness Despite the success of the company and focus on multi-brand development, the company experienced a serious financial recession in 2009. Apparently, the decline was due to the establishment of high-cost monopolized boutiques that were less competitive as compared to those offering multiple brands. Time-sensitivity was another issue that the Swatch Group had to face. Opportunity In order to follow the company mission to introduce value as a priority for product promotion, it was highly important to cooperate with the leading manufacturers of the watch parts, such as Nivarox (Deshpander et al. 5). In addition, the CEO of the Swatch Group, Nick Hayek, has introduced a new communication strategy focusing on developing brands and inviting such celebrities as Daniel Craig and George Clooney as sponsors. Threat A narrow-focused approach on branding campaign can limit the competitiveness of the company and introduce potential threat on the part of other competing businesses. Analysis With regard to the SWOT analysis, it is possible to highlight a range of brand strategies that a company has introduced to meet the customer demands. In particular, Hayek has introduced a multi-brand concept development that allowed to stay afloat and face all possible risks at losing a certain brand. Focus on brand development, on the one hand, might lead to the loss of certain consumers due to the ina bility of the producers to predict the needs and preferences. On the other hand, developing brand families based on innovation management is a step forward toward penetrating to an international market. Finally, maintaining a monopoly in brand development, which can lead to a less attractive image of the company’s product. Recommended Action Despite a well-organized and consistent strategy of promoting brand image through advancement of technology, development of brand families, and improving communication techniques, the company should still pay attention to the threat of their monopolized brand development.Advertising Looking for case study on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More Promoting a single brand to various markets can increase profitability, but for a short period because it is impossible to expand customer base endlessly. Therefore, the Swatch Group should work on expanding their cu stomer segments, but not on developing the concept of the Marketing Mix. Focus on product development and quality improvement should be a priority for the company to meet consumers’ fast-changing demands. Exploring new possibilities for enhancing product functionality is much more beneficial because it can change the fixed costs, as well as the controlling variables. Emphasis placed on technology innovation is relevant because it contributes to the development of new products and brands. However, the watch manufacturers should strike the balance between quality and functionality to meet the demands of broader market segments. Marketing Plan The marketing strategy of the Swatch Group should pay attention to high quality, low costs, and accurate watch materials. The main objective of the company consists in achieving innovation and creativity, which leads to expansion of the international market, as well as establishment of a strong brand loyalty among the consumers. The compan y’s marketing mix concept should consist of the following aspects: Target Market The target consumers of the Swatch Group involve those who are interested in exclusivity and exceptional quality. However, this segment is too narrow for the company to increase its revenues. The focus on uniqueness is beneficial, but the unique products can be sold at much lower prices. Such a strategy can expand the customer base significantly. Product The company provides greater opportunities for developing a wide range of products. However, creating a broad range of watches can lead to increased cost, which does not contribute to company’s profitability and performance.Advertising We will write a custom case study sample on SWOT Analysis Swatch Group specifically for you for only $16.05 $11/page Learn More Pricing The pricing strategy should be limited to the exclusiveness of the product and emphasize its high quality. Therefore, all products offered by the c ompany are of premium price. Apart from this strategy, the Swatch Group should also develop the strategy that would propose moderate prices to middle-class consumers. Promotion Interactive and direct promotion is possible through Internet because it can reach larger amounts of target customers. Therefore, the Swatch Group can introduce its advertisement on various websites. Distribution/Place Promotion strategy should be connected with strengthening the positions that have already been established. This strategy can increase the popularity of the brand and provide new opportunities for company’s development. Measurement In order to measure the outcomes, it is necessary to take control of the customer’s feedback placed on the websites, as well as the sales growth rates. In addition, the company can spend some time on research and development activities to define which segment of the market is the most active one and which one is passive. The latter can be identified as a weakness that can further be improved by the above-identified strategies. Deshpander, Rohit, Karol Misztal, and Daniela Beyersdorfer. â€Å"The Swatch Group†.

Biography of Tipu Sultan, the Tiger of Mysore

Biography of Tipu Sultan, the Tiger of Mysore Tipu Sultan (November 20, 1750–May 4, 1799) is remembered by many in India and Pakistan as a heroic freedom fighter and warrior-king. He was the last ruler in India strong enough to dictate terms to the British East India Company. Known as the Tiger of Mysore, he fought long and hard, although ultimately unsuccessfully, to preserve his countrys independence. Fast Facts: Tipu Sultan Known For:  He is remembered in India and Pakistan as a warrior-king who fought brilliantly for his countrys independence from Britain.Also Known As:  Fath Ali, Tiger of MysoreBorn:  November 20, 1750 in Mysore, IndiaParents: Hyder Ali and Fatima Fakhr-un-NisaDied:  May 4, 1799 in Seringapatam, Mysore, IndiaEducation: Extensive tutoringSpouse(s): Many wives, including Sindh Sahiba  Children: Unnamed sons, two of whom were held hostage by the BritishNotable Quote: To live like a lion for a day is far better than to live for a hundred years like a jackal. Early Life Tipu Sultan was born on November 20, 1750, to military officer Hyder Ali of the Kingdom of Mysore and his wife, Fatima Fakhr-un-Nisa. They named him Fath Ali but also called him Tipu Sultan after a local Muslim saint, Tipu Mastan Aulia. His father Hyder Ali was an able soldier and won such a complete victory against an invading force of Marathas in 1758 that Mysore was able to absorb the Marathan homelands. As a result, Hyder Ali became the commander-in-chief of Mysores army, later the Sultan, and by 1761 he was the outright ruler of the kingdom. While his father rose to fame and prominence, young Tipu Sultan was receiving an education from the finest tutors available. He studied such subjects as riding, swordsmanship, shooting, Koranic studies, Islamic jurisprudence, and languages such as Urdu, Persian, and Arabic. Tipu Sultan also studied military strategy and tactics under French officers from an early age, since his father was allied with the French in southern India. In 1766 when Tipu Sultan was just 15 years old, he got the chance to apply his military training in battle for the first time when he accompanied his father on an invasion of Malabar. The youngster took charge of a force of 2,000-3,000 and cleverly managed to capture the Malabar chiefs family, which had taken refuge in a fort under heavy guard. Fearful for his family, the chief surrendered, and other local leaders soon followed his example. Hyder Ali was so proud of his son that he gave him command of 500 cavalries and assigned him to rule five districts within Mysore. It was the start of an illustrious military career for the young man. First Anglo-Mysore War During the mid-18th century, the British East India Company sought to expand its control of southern India by playing local kingdoms and principalities off one another and off the French. In 1767, the British formed a coalition with the Nizam and the Marathas, and together they attacked Mysore. Hyder Ali managed to make a separate peace with the Marathas, and then in June he sent his 17-year-old son Tipu Sultan to negotiate with the Nizam. The young diplomat arrived in the Nizam camp with gifts that included cash, jewels, 10 horses, and five trained elephants. In just one week, Tipu charmed the ruler of the Nizam into switching sides and joining the Mysorean fight against the British. Tipu Sultan then led a cavalry raid on Madras (now Chennai) itself, but his father suffered a defeat by the British at Tiruvannamalai and had to call his son back. Hyder Ali decided to take the unusual step of continuing to fight during the monsoon rains, and together with Tipu he captured two British forts. The Mysorean army was besieging a third fort when British reinforcements arrived. Tipu and his cavalry held off the British long enough to allow Hyder Alis troops to retreat in good order. Hyder Ali and Tipu Sultan then went on a tear up the coast, capturing forts and British-held cities. The Mysoreans were threatening to dislodge the British from their key east coast port of Madras when the British sued for peace in March 1769. After this humiliating defeat, the British had to sign a 1769 peace agreement with Hyder Ali called the Treaty of Madras. Both sides agreed to return to their pre-war boundaries and to come to each others aid in case of attack by any other power. Under the circumstances, the British East India Company got off easy, but it still would not honor the treaty terms. Interwar Period In 1771, the Marathas attacked Mysore with an army perhaps as large as 30,000 men. Hyder Ali called upon the British to honor their duty of aid under the Treaty of Madras, but the British East India Company refused to send any troops to assist him. Tipu Sultan played a key role as Mysore fought off the Marathas, but the young commander and his father never trusted the British again. Later that decade, Britain and France came to blows over the 1776 rebellion (the American Revolution) in Britains North American colonies; France, of course, supported the rebels. In retaliation, and to draw off French support from America, Britain had decided to push the French entirely out of India. In 1778, it began to capture key French holdings in India such as Pondicherry, on the southeastern coast. The following year, the British grabbed the French-occupied port of Mahe on the Mysorean coast, prompting Hyder Ali to declare war. Second Anglo-Mysore War The Second Anglo-Mysore War (1780–1784), began when Hyder Ali led an army of 90,000 in an attack on the Carnatic, which was allied with Britain. The British governor at Madras decided to send the bulk of his army under Sir Hector Munro against the Mysoreans, and also called for a second British force under Colonel William Baillie to leave Guntur and meet up with the main force. Hyder got word of this and sent Tipu Sultan with 10,000 troops to intercept Baillie. In September 1780, Tipu and his 10,000 cavalry and infantry soldiers surrounded Baillies combined British East India Company and Indian force and inflicted on them the worst defeat the British had suffered in India. Most of the 4,000 Anglo-Indian troops surrendered and were taken prisoner, while 336 were killed. Colonel Munro refused to march to Baillies aid, for fear of losing the heavy guns and other material he had stored. By the time he finally set out, it was too late. Hyder Ali did not realize just how disorganized the British force was. Had he attacked Madras itself at that time, he likely could have taken the British base. However, he only sent Tipu Sultan and some cavalry to harass Munros retreating columns. The Mysoreans did capture all of the British stores and baggage and killed or wounded about 500 troops, but they did not attempt to seize Madras. The Second Anglo-Mysore War settled down into a series of sieges. The next significant event was Tipus February 18, 1782 defeat of East India Company troops under Colonel Braithwaite at Tanjore. Braithwaite was completely surprised by Tipu and his French ally General Lallà ©e and after 26 hours of fighting, the British and their Indian sepoys surrendered. Later, British propaganda said Tipu would have had them all massacred if the French hadnt interceded, but that is almost certainly false- none of the company troops were harmed after they surrendered. Tipu Takes the Throne While the Second Anglo-Mysore War was still raging, the 60-year-old Hyder Ali developed a serious carbuncle. His condition deteriorated throughout the fall and early winter of 1782, and he died on December 7. Tipu Sultan assumed the title of Sultan and took his fathers throne on December 29, 1782. The British hoped that this transition of power would be less than peaceful so that they would have an advantage in the ongoing war. However, Tipus smooth transition and immediate acceptance by the army thwarted them. In addition, British officers had failed to secure enough rice during the harvest, and some of their sepoys were literally starving to death. They were in no condition to launch an attack against the new sultan during the height of the monsoon season. Settlement Terms The Second Anglo-Mysore War went on until early 1784, but Tipu Sultan maintained the upper hand throughout most of that time. Finally, on March 11, 1784, the British East India Company formally capitulated with the signing of the Treaty of Mangalore. Under the terms of the treaty, the two sides once again returned to the status quo in terms of territory. Tipu Sultan agreed to release all of the British and Indian prisoners of war he had captured. Tipu Sultan the Ruler Despite two victories over the British, Tipu Sultan realized that the British East India Company remained a serious threat to his independent kingdom. He funded continuous military advances, including further development of the famous Mysore rockets- iron tubes that could fire missiles up to two kilometers, terrifying British troops and their allies. Tipu also built roads, created a new form of coinage, and encouraged silk production for international trade. He was particularly fascinated and delighted with new technologies and had always been an avid student of science and mathematics. A devout Muslim, Tipu was tolerant of his majority-Hindu subjects faith. Framed as a warrior-king and dubbed the Tiger of Mysore, Tipu Sultan proved an able ruler in times of relative peace as well. Third Anglo-Mysore War Tipu Sultan had to face the British for a third time between 1789 and 1792. This time, Mysore would receive no aid from its usual ally France, which was in the throes of the French Revolution. The British were led on this occasion by Lord Cornwallis, one of the major British commanders during the American Revolution. Unfortunately for Tipu Sultan and his people, the British had more attention and resources to invest in southern India this time around. Although the war lasted for several years, unlike past engagements, the British gained more ground than they gave. At the end of the war, after the British besieged Tipus capital city of Seringapatam, the Mysorean leader had to capitulate. In the 1793 Treaty of Seringapatam, the British and their allies, the Maratha Empire, took half of the territory of Mysore. The British also demanded that Tipu turn over two of his sons, ages 7 and 11, as hostages to ensure that the Mysorean ruler would pay war indemnities. Cornwallis held the boys captive to ensure that their father would comply with the treaty terms. Tipu quickly paid the ransom and recovered his children. Nonetheless, it was a shocking reversal for the Tiger of Mysore. Fourth Anglo-Mysore War In 1798, a French general named Napoleon Bonaparte invaded Egypt. Unbeknownst to his superiors in the Revolutionary government in Paris, Bonaparte planned to use Egypt as a stepping-stone from which to invade India by land (through the Middle East, Persia, and Afghanistan), and wrest it from the British. With that in mind, the man who would be emperor sought an alliance with Tipu Sultan, Britains staunchest foe in southern India. This alliance was not to be, however, for several reasons. Napoleons invasion of Egypt was a military disaster. Sadly, his would-be ally, Tipu Sultan, also suffered a terrible defeat. By 1798, the British had had sufficient time to recover from the Third Anglo-Mysore War. They also had a new commander of British forces at Madras, Richard Wellesley, Earl of Mornington, who was committed to a policy of aggression and aggrandizement. Although the British had taken half of his country and a large sum of money, Tipu Sultan meanwhile had rebuilt significantly and Mysore was once more a prosperous place. The British East India Company knew that Mysore was the only thing standing between it and total domination of India. A British-led coalition of nearly 50,000 troops marched toward Tipu Sultans capital city of Seringapatam in February 1799. This was no typical colonial army of a handful of European officers and a rabble of ill-trained local recruits; this army was made up of the best and brightest from all of the British East India Companys client states. Its single goal was the destruction of Mysore. Although the British sought to enclose Mysore state in a giant pincher movement, Tipu Sultan was able to sally out and stage a surprise attack early in March that nearly destroyed one of the British contingents before reinforcements showed up. Throughout the spring, the British pressed closer and closer to the Mysorean capital. Tipu wrote to the British commander Wellesley, trying to arrange for a peace  agreement, but Wellesley deliberately offered completely unacceptable terms. His mission was to destroy Tipu Sultan, not to negotiate with him. Death At the beginning of May 1799, the British and their allies surrounded Seringapatam, the capital of Mysore. Tipu Sultan had just 30,000 defenders matched against 50,000 attackers. On May 4, the British broke through the city walls. Tipu Sultan rushed to the breach and was killed defending his city. After the battle, his body was discovered beneath a pile of defenders. Seringapatam was overrun. Legacy With Tipu Sultans death, Mysore became another princely state under the jurisdiction of the British Raj. His sons were sent into exile, and a different family became puppet rulers of Mysore under the British. In fact, Tipu Sultans family was reduced to poverty as a deliberate policy and was only restored to princely status in 2009. Tipu Sultan fought long and hard, although ultimately unsuccessfully, to preserve his countrys independence. Today, Tipu is remembered by many in India and Pakistan as a brilliant freedom fighter and as an able peacetime ruler. Sources Britains Greatest Foes: Tipu Sultan.

Public Employees Essay Example | Topics and Well Written Essays - 500 words

Public Employees - Essay Example This essay discusses the benefits of the patronage system versus the merit system for public employee. First, the patronage system refers to a system where public employees are hired or dismissed based on the support of an individual candidate or the political system. When a candidate belonging to a certain political party wins an election, they have the right to appoint a given number of individuals into public positions (Farazmand, 2007). This is the real meaning of the patronage system that is commonly referred to as the spoils system. The appointment of these individuals is based on political support rather than merit as the appointment criteria. Although the patronage system exists across the various levels in the US government, the number of positions offered through this system has reduced drastically since the 1880s. In fact, the system existed in the US until 1883 with the enactment of the Pendleton Civil Service Reform Act of 1883. In 1820, congress set a limit of the federal administrators to four years and this lead to an increase in the public employees’ turnover (Dautrich and Yalof, 2013). By the 1860s, the patronage system and the civil war had led to increased corruption and widespread inefficiency in the public service and had spread to low rank government positions. There are numerous benefits associated with the patronage or spoilers system. To start with, the system helps put in place a well-organized political system that rewards campaign workers. The system also puts individuals who agree with the political agenda in power thus promotion cooperation, trust and loyalty within the public service. The system ensures continuous turnover and this brings new individuals and ideas into the system. This system was replaced by the Merit system when the Pendleton Civil Service Reform Act of 1883 was enacted (Dautrich and Yalof, 2013). The Pendleton Civil Service Reform Act of 1883 specified that public jobs

CONSTRUCTING AN INTERNATIONAL REAL ESTATE PORTFOLIO - Coursework Example Implementation complexities in constructing an effective portfolio possess risk factors, which make it necessary for crucial exposure and assessment of opportunities for the investment in the international real estate market. There has been an increase in international investments especially in international real estate markets, which is clear from the UK listed and unlisted wholesale markets. It is evident that most products fall under the value-added or opportunistic and risk or reward; hence they offer a wide range of the investments returns. The international listed real estate funds have different collective strategies according to different regions as indicated by fig.1. There is a variation of real estate types depending on the countries or country targeted. Consequently, there are different ways of gaining exposure to the investable market. Various options are employed to acquire and manage equity interests for international real estate investments. The aim of the paper is to discuss the advantages and disadvantages of applying various methods for gaining exposure to the real estate investments. In addition, it evaluates the different methods used to fully acquire and manage equity interests in international real estate investments. Real estate refers to; the commercial sectors of office, retail, industrial, and leased residential real estate sectors. The real estate appraisers in the UK reflect value of asset factors such as expected income growth, risk of liquidity, management costs, income growth related risks, and the tenant default risk that enables the capitalization of the current and future income expectations and streams. This indicates that the international real estate investment can offer a number of investment features that have different risk levels. The different investment procedures makes it possible for the income streams to be cut in many ways and offers

Free Space Optics Essay ABSTRACT: FSO may sound new and experimental but in fact it predates optical fiber and has its roots in wartime efforts to develop secure communication systems that did not require cable and could withstand radio jamming. FSO has been around for more than a decade, but it is only recently that interest in this technology has started to grow. Free Space Optics (FSO) communications, also called Free Space Photonics (FSP) or Optical Wireless, refers to the transmission of modulated visible or infrared (IR) beams through the atmosphere to obtain optical communications. Like fiber, Free Space Optics (FSO) uses lasers to transmit data, but instead of enclosing the data stream in a glass fiber, it is transmitted through the air. Free Space Optics (FSO) works on the same basic principle as Infrared television remote controls, wireless keyboards or wireless Palm ® devices. How Free Space Optics (FSO) Works Free Space Optics (FSO) transmits invisible, eye-safe light beams from one telescope to another using low power infrared laser in the terahertz spectrum. The beams of light in Free Space Optics (FSO) systems are transmitted by laser light focused on highly sensitive photon detector receivers. These receivers are telescopic lenses able to collect the photon stream and transmit digital data containing a mix of Internet messages, video images, radio signals or computer files. Commercially available systems offer capacities in the range of 100 Mbps to 2.5 Gbps, and demonstration systems report data rates as high as 160 Gbps. Free Space Optics (FSO) systems can function over distances of several kilometers. As long as there is a clear line of sight between the source and the destination, and enough transmitter power, Free Space Optics (FSO) communication is possible. [pic] Free Space optics (fso) technology Lasers are one of the most significant inventions of the 20th century they can be found in many modern products, from CD players to fiber-optic networks. A laser generates light, either visible or infrared, through a process known as stimulated emission. To understand stimulated emission, understanding two basic concepts is necessary. The first is absorption which occurs when an atom absorbs energy or photons. The second is emission which occurs when an atom emits photons. Emission occurs when an atom is in an excited or high energy state and returns to a stable or ground state – when this occurs naturally it is called spontaneous emission because no outside trigger is required. Stimulated emission occurs when an already excited atom is bombarded by yet another photon causing it to release that photon along with the photon which previously excited it. Photons are particles, or more properly quanta, of light and a light beam is made up of what can be thought of as a stream of photons. [pic] A basic laser uses a mirrored chamber or cavity to reflect light waves so they reinforce each other. An excitable substance – gas, liquid, or solid like the original ruby laser – is contained within the cavity and determines the wavelength of the resulting laser beam. Through a process called pumping, energy is introduced to the cavity exciting the atoms within and causing a population inversion. A population inversion is when there are more excited atoms than grounded atoms which then leads to stimulated emission. The released photons oscillate back and forth between the mirrors of the cavity, building energy and causing other atoms to release more photons. One of the mirrors allows some of the released photons to escape the cavity resulting in a laser beam emitting from one end of the cavity. Terrestrial Laser CommunicatIOns Challenges FogFog substantially attenuates visible radiation, and it has a similar affect on the near-infrared wavelengths that are employed in laser communications. Similar to the case of rain attenuation with RF wireless, fog attenuation is not a â€Å"show-stopper† for optical wireless, because the optical link can be engineered such that, for a large fraction of the time, an acceptable power will be received even in the presence of heavy fog. Laser communication systems can be enhanced to yield even greater availabilities by combining them with RF systems. Physical Obstructions Laser communications systems that employ multiple, spatially diverse transmitters and large receive optics will eliminate interference concerns from objects such as birds. Pointing Stability Pointing stability in commercial laser communications systems is achieved by one of two methods. The simpler, less costly method is to widen the beam divergence so that if either end of the link moves the receiver will still be within the beam. The second method is to employ a beam tracking system. While more costly, such systems allow for a tighter beam to be transmitted allowing for higher security and longer distance transmissions. Scintillation Performance of many laser communications systems is adversely affected by scintillation on bright sunny days. Through a large aperture receiver, widely spaced transmitters, finely tuned receive filtering, and automatic gain control, downtime due to scintillation can be avoided. FSO: Wireless, at the Speed of Light Unlike radio and microwave systems, Free Space Optics (FSO) is an optical technology and no spectrum licensing or frequency coordination with other users is required, interference from or to other systems or equipment is not a concern, and the point-to-point laser signal is extremely difficult to intercept, and therefore secure. Data rates comparable to optical fiber transmission can be carried by Free Space Optics (FSO) systems with very low error rates, while the extremely narrow laser beam widths ensure that there is almost no practical limit to the number of separate Free Space Optics (FSO) links that can be installed in a given location. How Free Space Optics (FSO) can help? FSO’s freedom from licensing and regulation translates into ease, speed and low cost of deployment. Since Free Space Optics (FSO) transceivers can transmit and receive through windows, it is possible to mount Free Space Optics (FSO) systems inside buildings, reducing the need to compete for roof space, simplifying wiring and cabling, and permitting Free Space Optics (FSO) equipment to operate in a very favorable environment. The only essential requirement for Free Space Optics (FSO) or optical wireless transmission is line of sight between the two ends of the link. For Metro Area Network (MAN) providers the last mile or even feet can be the most daunting. Free Space Optics (FSO) networks can close this gap and allow new customer’s access to high-speed MAN’s. Providers also can take advantage of the reduced risk of installing an Free Space Optics (FSO) network which can later be redeployed. The Market. Why FSO? Breaking the Bandwidth Bottleneck Why FSO? The global telecommunications network has seen massive expansion over the last few years. First came the tremendous growth of the optical fiber long-haul, wide-area network (WAN), followed by a more recent emphasis on metropolitan area networks (MANs). Meanwhile, local area networks (LANs) and gigabit ethernet ports are being deployed with a comparable growth rate. In order for this tremendous network capacity to be exploited, and for the users to be able to utilize the broad array of new services becoming available, network designers must provide a flexible and cost-effective means for the users to access the telecommunications network. Presently, however, most local loop network connections are limited to 1.5 Mbps (a T1 line). As a consequence, there is a strong need for a high-bandwidth bridge (the â€Å"last mile† or â€Å"first mile†) between the LANs and the MANs or WANs. A recent New York Times article reported that more than 100 million miles of optical fiber was laid around the world in the last two years, as carriers reacted to the Internet phenomenon and end users’ insatiable demand for bandwidth. The sheer scale of connecting whole communities, cities and regions to that fiber optic cable or â€Å"backbone† is something not many players understood well. Despite the huge investment in trenching and optical cable, most of the fiber remains unlit, 80 to 90% of office, commercial and industrial buildings are not connected to fiber, and transport prices are dropping dramatically. Free Space Optics (FSO) systems represent one of the most promising approaches for addressing the emerging broadband access market and its â€Å"last mile† bottleneck. Free Space Optics (FSO) systems offer many features, principal among them being low start-up and operational costs, rapid deployment, and high fiber-like bandwidths due to the optical nature of the technology. Broadband Bandwidth Alternatives Access technologies in general use today include telco-provisioned copper wire, wireless Internet access, broadband RF/microwave, coaxial cable and direct optical fiber connections (fiber to the building; fiber to the home). Telco/PTT telephone networks are still trapped in the old Time Division Multiplex (TDM) based network infrastructure that rations bandwidth to the customer in increments of 1.5 Mbps (T-1) or 2.024 Mbps (E-1). DSL penetration rates have been throttled by slow deployment and the pricing strategies of the PTTs. Cable modem access has had more success in residential markets, but suffers from security and capacity problems, and is generally conditional on the user subscribing to a package of cable TV channels. Wireless Internet access is still slow, and the tiny screen renders it of little appeal for web browsing. Broadband RF/microwave systems have severe limitations and are losing favor. The radio spectrum is a scarce and expensive licensed commodity, sold or leased to the highest bidder, or on a first-come first-served basis, and all too often, simply unavailable due to congestion. As building owners have realized the value of their roof space, the price of roof rights has risen sharply. Furthermore, radio equipment is not inexpensive, the maximum data rates achievable with RF systems are low compared to optical fiber, and communications channels are insecure and subject to interference from and to other systems (a major constraint on the use of radio systems). Advantages A free space optical (FSO) system offers a flexible networking solution that delivers on the promise of broadband. Only free space optics or Free Space Optics (FSO) provides the essential combination of qualities required to bring the traffic to the optical fiber backbone – virtually unlimited bandwidth, low cost, ease and speed of deployment. Freedom from licensing and regulation translates into ease, speed and low cost of deployment. Since Free Space Optics (FSO) optical wireless transceivers can transmit and receive through windows, it is possible to mount Free Space Optics (FSO) systems inside buildings, reducing the need to compete for roof space, simplifying wiring and cabling, and permitting the equipment to operate in a very favorable environment. The only essential for Free Space Optics (FSO) is line of sight between the two ends of the link. âž ¢ Freedom from licensing and regulation leads to ease, speed and low cost of deployment. âž ¢ Since FSO units can receive and transmit through windows it reduces the need to compete for roof space, simplifying wiring and cabling. âž ¢ Only need is the line of sight between the two ends of the link. âž ¢ Providers take advantage of the reduced risk in installing FSO equipment, which can even be re-deployed. âž ¢ Zero chances of network failure. âž ¢ Virtually unlimited bandwidth. APPLICATIONS âž ¢ Metro network extensions – FSO is used to extend existing metropolitan area fiberings to connect new networks from outside. âž ¢ Last mile access – FSO can be used in high-speed links to connect end users with ISPs. âž ¢ Enterprise connectivity The ease in which FSO can be installed makes them a solution for interconnecting LAN segments, housed in buildings separated by public streets. âž ¢ Fiber backup FSO may be deployed in redundant links to backup fiber in place of a second fiber link. âž ¢ Backhaul – Used to carry cellular telephone traffic from antenna towers back to facilities into the public switched telephone networks. Free Space Optics (FSO) Challenges The advantages of free space optical wireless or Free Space Optics (FSO) do not come without some cost. When light is transmitted through optical fiber, transmission integrity is quite predictable – barring unforeseen events such as backhoes or animal interference. When light is transmitted through the air, as with Free Space Optics (FSO) optical wireless systems, it must contend with a complex and not always quantifiable subject the atmosphere. âž ¢ Fog and free space optics (fso) âž ¢ Physical obstructions and free space optics (fso) âž ¢ Free space optics (fso) pointing stability – building sway, tower movemen t âž ¢ Scintillation and free space optics (fso) âž ¢ Solar interference and free space optics CONCLUSION FSO enables optical transmission of voice video and data through air at very high rates. It has key roles to play as primary access medium and backup technology. Driven by the need for high speed local loop connectivity and the cost and the difficulties of deploying fiber, the interest in FSO has certainly picked up dramatically among service providers worldwide. Instead of fiber coaxial systems, fiber laser systems may turn out to be the best way to deliver high data rates to your home. FSO continues to accelerate the vision of all optical networks cost effectively, reliably and quickly with freedom and flexibility of deployment.

The Good and Evil Angelo of Measure for Measure Essay -- Measure for M

The Good and Evil Angelo of Measure for Measure   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚   In Shakespeare's Measure for Measure, Angelo emerges as a double-sided character.   Scholars have argued for centuries whether or not Angelo is a moral character or an evil character.   Those scholars who support the notion of Angelo as moral often cite the following facts: the Duke obviously trusts Angelo, Angelo is disheartened enough by the end of the play to offer a sincere apology, and Angelo tries to resist the temptation that Isabella presents.   On the other hand, others have argued that Shakespeare depicts Angelo as a purely evil man.   These critics emphasize Angelo's treatment of Marian, the Duke's possible suspicion of Angelo, his desire for Isabella, and his broken promise to Isabella.   By examining Angelo in both of these circumstances, it will become apparent that the most successful interpretation of Angelo's character is a combination of both of these facets.    Angelo depicts a few moral qualities throughout the course of the play.   The firs instance of Angelo's depiction as a possible moral figure occurs in Act I, scene i.   It becomes apparent here that the Duke has enough trust in Angelo to leave him in charge of his people.   The Duke tells Angelo that he has the power to "enforce or qualify the laws/ As to your soul seems good" (I.i.66-67), which demonstrates that he must feel some respect for Angelo.   Obviously, if Angelo does a poor job, it will reflect poorly on the Duke's judgment as a leader.   Therefore, it would appear to be a foolish move if the Duke left Angelo in charge and assumed that Angelo might do something disreputable (Rowse 360).   On top of this, the Duke's speeches demonstrate that he is an intelligent, sensitive man w... ...randes, Georg.   William Shakesperea.   New York: Macmillian Company, 1924, pp. 401-10 Parrott, Thomas marc.   Shakespearean Comedy.   New York: Russel and Russel, Inc., 1949, pp. 335-65.

Political And Economic Globalization Essay

Globalization in whichever form has received different view from different people all over the world. It has always portrayed two faces in any field in which it was applied. Generally, globalization has its roots in economic and political concerns. These two areas are key factors which touches the lives of people in any country, hence, globalization in either economic or politics will most if not always affect the ways of life in any given country. The consequences of economic and political globalizations are thus paramount in the induction of particular changes in the cultural ways of these communities. The economic and political globalization has an impact on culture while at the same time the cultures have enormous impacts on the globalization of both. This is because there is an intimate interrelationships and integration of the three human activities which builds the human life. Thus, from the historical view of the three things, they have gone hand in hand for complete human life existence. Globalization of politics and economic are two key factors which are affecting the culture of modern world bringing about cultural homogeneity rather than cultural diversity. In reality, this has made crowds of people to remain perplex on which ways is these economic and political globalizations is driving the culture. (Mudimbe-boyi, 2002) Meanwhile, globalization has also allowed the cultural diversity tpo surface as countries started to accept the globalized views and ways of life. The more global influences get in the culture, the more chance that the community acknowledges the uniqueness of its culture. First and foremost are that many people having experiences obstacles of understanding what is culture and the compositions of culture. Michael Amaladoss gave any efforts of defining culture. He said â€Å"culture is the way of a life of a people through which they humanize and socialize nature. † In his further elaboration, he mentioned that it implies the world-view, a value system and a network of social relationships. There are key areas in which during economics and political globalization, they are obviously affected. The effects are felt when many people changes their values system and the original products which were once used by their forefathers. This phenomenon is not rare in most parts of the world where many people have gone under the transition of economic and political globalization. There are numerous alarming cultural practices which the world’s leaders are now struggling to ban as result of this two globalizes factors. (Cowen, 2002) In some instances however, globalization becomes a driving force for people to realize how cultural affinities are being ignored. As people in different communities strive to adopt into the globalized world, they start to be more keen on its effects in the culture, thus the rise of groups concerned with protecting and/or preserving the cultural heritage. It has also served as the venue for countries to showcase the unique culture to the entire world. Globalization of economy and politics are not bring along with cultural diversity. Generally, each globalization processes are working ways out to have homogeneity of cultures. For instance, in terms of economic globalization in the sectors of agriculture sectors, the world’s organizations which deal with the problems of foods shortages do not address the problem from root cause of the shortages. Their models hardly emphasizes on the available establishment of these local food stuff in the particular countries. Instead, they widely and vast get involved in the use of imports to solve the problems of hungers. Through such means the cultural foods products of the native communities in these states are set into extinction as the local are encouraged to embark on sowing new types of crops. This portrays that there is expansion of the culture from one point of country to another through these aids creating a homogenous cultures. (Adam, 2002) But because of the uniqueness of the cultures of each country, cultural differences will most likely affect how a country reacts to a globalized world, or how a country respond to globalization. Globalization can sometimes tend to be too Westernized that countries from Asia or from other part of the world will find it hard to adopt, thus resulting to further cultural diversity rather than homogeneity. Their global information infrastructures which as come on the ways of technology and industrialization has made trade increases. In addition, to trade many countries have been subjects to comply with unnecessary economic condition. This has especially affected those developing countries where resources and job opportunities are limited. The unfavorable economic environments in those states have created a loophole for the exploitation of the people. The people are being forced by worse survival means to adapts the foreign culture so that they can attain their goals in life. As the adage goes â€Å"power and wealthy and there to conquers and dominates the weak†. (Cowen, 2002) Meanwhile, globalization has also helped developing countries. An example is for developing countries in Asia such as Philippines and India who have become an ideal venue for the support needs of the economies of the US and other countries in Europe. This has paved the way for the booming business processing outsourcing (BPO) industries in these countries due to globalization. The political globalizations are largely affecting the culture of these different communities of the world in the pretence of fighting for human rights. The politics from the westerns and Americans have spreads in all corners of the worlds in which the Americans are fighting to have democratic political area. Political globalists has intervened in issues of marriages and other matters which touches family affairs. Argument such as homosexuals and other related family matters have been widely politicized debates which have been accelerated by political globalization. The consequences of this embarked in the developments countries which are majority pro- globalisms. The final result is that, the continued interaction of the people in the economic dispersions in the trades industries wits such peoples has enables the spreading of the vices to thousands of countries in other continents. Gayism and lesbians are two vices which did not exist in African continents in date of the previous two centuries back. The perpetual globalization on economic and politics has spread this scourge disease to the continent in the last four to five decades. This vividly demonstrates, that the cultures which had rooted values in the continent has been absorbed creating some support of homogeneous culture rather than cultural diversity. (Mudimbe-boyi, 2002) In the same way, the share of culture had also positive effect on other communities. People become more informed of how things are done in the other parts of the world, and thus they are able to establish benchmarks. These will then become a basis of the right way of doing things by using these as models on how to successfully deal with political and economic concerns. Reference: Adam, D.

Education in America vs. Education in Third World Countries

Education in America vs. Education in Third World Countries A few weeks ago, I was walking downtown, when this random came up to me and said â€Å"You in school? That’s good, that’s good. Education is important. † From the state of her hair and clothes, and the smell of her breath, I assumed she was homeless. I didn’t really pay much attention to her, because homeless people are so common in downtown Atlanta. I was just hoping that she wasn’t going to ask me for any money! After a while, I started thinking about what the homeless woman had said; â€Å"Education is important. Growing up, I had always been taught that people who lived in the streets had been afforded the same opportunities as I had, but they had simply chosen to ignore them. So, if this woman had basically thrown away her life, why was she here preaching to me that education was important? How far had she gotten with her education? Was she like my great-grandmother, and lacked the sk ills to read and write? Literacy isn’t something that I spend a lot of time thinking about, mainly because all of the people that I surround myself and the people they surround themselves with are all capable of reading at proficient levels.Of course, I was always aware that some people had disabilities that made it harder to read, like dyslexia, but it never occurred to me that some of them allowed for the hindrance to completely turn them off to reading. Is it possible that I have been taking my literacy skills for granted? In this paper, I plan to explore literacy in America, and how it compares to the value other nations put on literacy and even our own country before public schools were instituted. Being literate is defined as any person over the age of 15 that can read and write.The United States had a literacy rate of 99% in the year 2003, according to the CIA census. 99%; almost our entire population is capable of reading and writing at a proficient level. Who does th e least 1% represent? The homeless? Or the dyslexic people who are too embarrassed to admit they need help reading? Every person in America is offered the opportunity to receive an education, admittedly some educations are not the same quality as others, but everyone is definitely offered an education.While 99% of the country is literate, a test conducted by National Assessment of Adult Literacy 14% of US residents have increased difficulty reading at their level. According to the afore stated definition, these people can be classified as illiterate, because they don’t met the standards of what is considered literate, since they have difficulty reading at their proficiency level. Is the lack of literacy due to lack of focus in class while the foundation for reading and writing were being laid, or does 1% of the United States Population that are classified as illiterate completely comprised of people who live with dyslexia?I can’t imagine that the government would knowi ngly incorporate people with documented learning disabilities when it comes time to calculate our nation’s literacy rate. That would be almost intentionally miscuing the results, because you’re including people who have hindrances that keep them from reading and writing at a level equal with their age. It’s also just downright insulting. Can you imagine not only having the s disability that makes you work twice as hard, but to be called illiterate for something you have no control over?Centuries ago, the idea of being able to read and write was a mere parlor dream among the majority of our population. The skill was reserved only for the kings and queens and the other extremely wealthy people of that time period. The commoners who truly wanted a better life for their children would probably have sold everything they owned if it meant their child would have the opportunity to learn to read and write. In today’s society, however, such sacrifices are not nece ssary to make. Our government ensures that an education is made ready to every child in the country.Education is such an available resource in our country that we don’t even think twice about it. We are inevitable taking it for granted. When did such knowledge become common place to us? There are times when I visit my great-grandparents house, and they start telling me all sorts of stories about how they didn’t even get to complete more than a third grade education, because they had to stop going to school in order to support their families. That was their reality; not having that education as available to them as other kids did.The richer, white families of that time period where the only ones who could afford to send their children to school on a daily basis, some even going as far as to ensure that their child received a quality college education. It often came down to that; money. In the end, it will always be the richer families, or even the richest countries that can afford to educate their youth. In lower-income developing nations, going to school is nowhere near a reality. The idea of buying money enough to buy school clothes, shoes, books, paper, encils, and any other supplies necessary for the learning environment is non-existent, because there just isn’t enough money for them to afford it. These are the absolute poorest places in the world; particularly Africa . Every time I turn on a television, regardless of what channel I may be watching, I am almost guaranteed to see a commercial about a charity trying to raise money to support the children in Africa . It’s heartbreaking, to say the least, to see the sad expressions on their sallow faces. I think to myself, that’s not what I was doing when I was 5 or 6. I was outside, playing in the yard, or stuffing my face with ice cream.I wasn’t worried about where my next meal would come from, or whether or not my only water source was toxic enough to kill me. The sa ddest thing I can remember about my younger days is when my parents forced me off the jungle gym to do my homework, because I like any other kid my age, hated reading and writing. Not because it was hard, or even that I was being required to do it; I hated reading and writing because that’s what we always did. Every day, for most of my day, the teacher had us reading directions aloud and writing spelling words and sentences over and over and over again.However, had I switched places with one of those sad-faced kids in Africa , they would have never complained about the amount of reading and writing required of them. They would have relished every single second of the knowledge that they gained in hopes of one day using it to help their families get to a better place. In those types of countries, literacy is to them as it was to us back when the only people who could afford to learn where the ones who didn’t have to work from sunrise to sunset in order to keep their fam ilies from starving.There, education is one of the most valuable resources, because so few have access to it. I remember learning in an economics class that the less you had of a product, the more valuable it became, like diamonds or oil, and vice versa; the more you have of a product, the less valuable it becomes. That’s what happened to our value on literacy in America . Before, when only a few people were awarded the privilege of learning how to read and write, everyone wanted it. I guess you could almost compare it to fads in today’s society.Whenever we see our favorite A-list celebrities wearing this bag or that hat, we rush out to the nearest boutique, and pay whatever ridiculous price they ask for it. Maybe that’s it. Since literacy and education have become so common place in our society that we have moved on another aspect to occupy our attention. Think about it for a moment. How many people in the United States have a Bachelor’s degree? A Master ’s degree? According to U. S. Census Bureau more than 40% of people 25 years and older in the United States has either a Bachelor’s or a Master’s degree.There’s a saying, â€Å"When everyone is one thing, then no one will be. † Well, in this case when everyone is smart, then no one will be. Since a large enough portion of our population has these degrees, they are slowly starting to lose their value. Even some fast food restaurants are beginning to require that people over a certain age have to have at least a Bachelor’s degree in order to work at their establishment. What does this say for our future? Will we eventually reach a point where even a Doctorate degree holds no value in our economy?What will that mean for the homeless people, or those individuals with learning disabilities, or even people who just have a genuinely hard time keeping up with their course load? Will they be weeded out as Charles Darwin’s theory of evolution s uggests â€Å"Only the strong survive†? But in this case, the strongest are defined by their intelligence. Will they all eventually starve due to the fact that they can’t find a job, because standards are set so high? If the current trend continues, I think it’s definitely possible that eventually even the Doctorate degree will hold no real value.Especially with the way our counselor’s motivate us. They tell us that it’s not just enough to get an â€Å"old-fashioned† 4-year degree anymore, because that’s what everyone has already. No, if we want to compete in the job market, we have to set ourselves above that bar. Logically, that supports my hypothesis. Just think about it for a second. You’re telling an entire generation of kids that the generation that came before them did the now-average-thing by attending four-year institutions.Now we have to go up and beyond that, by obtaining our graduate degrees, and if we really want t o raise the bar, going as far as to earn our Doctorate. Where does that leave the generation that comes after us? In the same position we find ourselves in now. The problem with our country is not that we take literacy for granted. On the contrary, we are steadily improving and bettering ourselves by pushing each generation to do better than the last. Our problem lies with the fact that eventually; there will be no more up to go.

Sex Chromosome Abnormalities

Sex Chromosome Abnormalities Sex chromosome abnormalities occur as a result of chromosome mutations brought on by mutagens (like radiation) or problems that occur during meiosis. One type of mutation is caused by chromosome breakage. The broken chromosome fragment may be deleted, duplicated, inverted, or translocated to a non-homologous chromosome. Another type of mutation occurs during meiosis and causes cells to have either too many or not enough chromosomes. Alterations in the number of chromosomes in a cell can result in changes in an organisms phenotype or physical traits. Normal Sex Chromosomes In human sexual reproduction, two distinct gametes fuse to form a zygote. Gametes are reproductive cells produced by a type of cell division called meiosis. They contain only one set of chromosomes and are said to be haploid (one set of 22 autosomes and one sex chromosome). When the haploid male and female gametes unite in a process called fertilization, they form what is called a zygote. The zygote is diploid, meaning that it contains two sets of chromosomes (two sets of 22 autosomes and two sex chromosomes). The male gametes, or sperm cells, in humans and other mammals are heterogametic and contain one of two types of sex chromosomes. They have either an X or a Y sex chromosome. However, the female gametes or eggs contain only the X sex chromosome and are homogametic. The sperm cell determines the sex of an individual in this case. If a sperm cell containing an X chromosome fertilizes an egg, the resulting zygote will be XX or female. If the sperm cell contains a Y chromosome, then the resulting zygote will be XY or male. X and Y Chromosome Size Difference The Y chromosome carries genes that direct the development of male gonads and the male reproductive system. The Y chromosome is much smaller than the X chromosome (about 1/3 the size) and has fewer genes than the X chromosome. The X chromosome is thought to carry around two thousand genes, while the Y chromosome has less than one hundred genes. Both chromosomes were once about the same size. Structural changes in the Y chromosome resulted in the rearrangement of genes on the chromosome. These changes meant that recombination could no longer occur between large segments of the Y chromosome and its X homologue during meiosis. Recombination is important for weeding out mutations, so without it, mutations accumulate faster on the Y chromosome than on the X chromosome. The same type of degradation is not observed with the X chromosome because it still maintains the ability to recombine with its other X homologue in females. Over time, some of the mutations on the Y chromosome have resulted in the deletion of genes and have contributed to the decrease in the size of the Y chromosome. Sex Chromosome Abnormalities Aneuploidy is a condition characterized by the presence of an abnormal number of chromosomes. If a cell has an additional chromosome, (three instead of two), it is trisomic for that chromosome. If the cell is missing a chromosome, it is monosomic. Aneuploid cells occur as a result of either chromosome breakage or nondisjunction errors that happen during meiosis. Two types of errors occur during nondisjunction: homologous chromosomes dont separate during anaphase I of meiosis I or sister chromatids dont separate during anaphase II of meiosis II.Nondisjunction results in some abnormalities, including: Klinefelter syndrome is a disorder in which males have an extra X chromosome. The genotype for males with this disorder is XXY. People with Klinefelter syndrome may also have more than one extra chromosome resulting in genotypes which include XXYY, XXXY, and XXXXY. Other mutations result in males that have an extra Y chromosome and a genotype of XYY. These males were once thought to be taller than average males and overly aggressive based on prison studies. Additional studies, however, have found XYY males to be normal.Tuner syndrome is a condition that affects females. Individuals with this syndrome, also called monosomy X, have a genotype of only one X chromosome (XO).Trisomy X females have an additional X chromosome and are also referred to as metafemales (XXX). Nondisjunction can occur in autosomal cells as well. Down syndrome is most commonly the result of nondisjunction affecting autosomal chromosome 21. Down syndrome is also referred to as trisomy 21 because of the extra chrom osome. The following table includes information on sex chromosome abnormalities, resulting syndromes, and phenotypes (expressed physical traits). Genotype Sex Syndrome Physical Traits XXY, XXYY, XXXY male Klinefelter syndrome sterility, small testicles, breast enlargement XYY male XYY syndrome normal male traits XO female Turner syndrome sex organs dont mature at adolescence, sterility, short stature XXX female Trisomy X tall stature, learning disabilities, limited fertility Sex Chromosome Abnormalities

Understanding Quantum Optics

Understanding Quantum Optics Quantum optics is a field of quantum physics that deals specifically with the interaction of photons with matter. The study of individual photons is crucial to understanding the behavior of electromagnetic waves as a whole. To clarify exactly what this means, the word quantum refers to the smallest amount of any physical entity that can interact with another entity. Quantum physics, therefore, deals with the smallest particles; these are incredibly tiny sub-atomic particles which behave in unique ways. The word optics, in physics, refers to the study of light. Photons are the smallest particles of light (though it is important to know that photons can behave as both particles and waves). Development of Quantum Optics and the Photon Theory of Light The theory that light moved in discrete bundles (i.e. photons) was presented in Max Plancks 1900 paper on the ultraviolet catastrophe in black body radiation. In 1905, Einstein expanded on these principles in his explanation of the photoelectric effect to define the photon theory of light. Quantum physics developed through the first half of the twentieth century largely through work on our understanding of how photons and matter interact and inter-relate. This was viewed, however, as a study of the matter involved more than the light involved. In 1953, the maser was developed (which emitted coherent microwaves) and in 1960 the laser (which emitted coherent light). As the property of the light involved in these devices became more important, quantum optics began being used as the term for this specialized field of study. Findings Quantum optics (and quantum physics as a whole) views electromagnetic radiation as traveling in the form of both a wave and a particle at the same time. This phenomenon is called wave-particle duality. The most common explanation of how this works is that the photons move in a stream of particles, but the overall behavior of those particles is determined by a quantum wave function that determines the probability of the particles being in a given location at a given time. Taking findings from quantum electrodynamics (QED), it is also possible to interpret quantum optics in the form of the creation and annihilation of photons, described by field operators. This approach allows the use of certain statistical approaches that are useful in analyzing the behavior of light, although whether it represents what is physically taking place is a matter of some debate (although most people view it as just a useful mathematical model). Applications Lasers (and masers) are the most obvious application of quantum optics. Light emitted from these devices is in a coherent state, which means the light closely resembles a classical sinusoidal wave. In this coherent state, the quantum mechanical wave function (and thus the quantum mechanical uncertainty) is distributed equally. The light emitted from a laser is, therefore, highly ordered, and generally limited to essentially the same energy state (and thus the same frequency wavelength).

The Illnesses of the Government Policy Essay Example | Topics and Well Written Essays - 1250 words

The Illnesses of the Government Policy - Essay Example Social work has a significant role in helping these ex-convicts achieve greater self-efficacy outside the prison walls through enhancing their access to related basic social and health services and helping them build the relationships and resources they need for their welfare.   At the least. The government understands that the mentally ill cannot possibly care for their welfare immediately after imprisonment. As a result, it provides a free bus ticket, some pocket money, and two weeks of medication. At least, the government does not completely leave them empty-handed. In â€Å"Research Protections for Diverted Mentally Ill Individuals: Should They Be Considered Prisoners?† Amory, Amrhein, and Dery (2011) studied the concept and practice of diversion for mentally ill offenders and reviewed the literature on the concepts of â€Å"coercion,† â€Å"informed consent† and â€Å"decisional capacity† of imprisoned mentally ill individuals. They discussed the existing diversion programs for these kinds of prisoners. They explained that government policy provides pre-booking and post-booking programs that direct the mentally ill away from the traditional criminal justice system (Amory, Amrhein, & Dery, 2011, p.797). These programs help them access the medical attention they need, instead of being imprisoned only.   Possibilities for improvements. The government policy on mentally ill offenders can be amended. It can be enhanced to boost the support for these offenders. The main emphases are on their preparation for freedom.

Brand community Essay Example | Topics and Well Written Essays - 2500 words

Brand community - Essay Example Brand community is a set of individuals who relate to each other for their interest in some brand or product (Flavià ¡n & Guinalà ­u, 2005). Such brand communities have become the focus of attention for marketers of all products and services. Sports and particularly football has become big business, drawing the attention to brand communities. The brands communities, according to Seo et al., are not bound by personal relations but are based on looser, more impersonal links. The strength of the community and the members’ identification with the community are associated with consumers’ consumption of the core product or product augmentations or brand extensions. The members of the community feel an intrinsic connection with one another which Muniz, Albert and O’Guinn describe as ‘consciousness of kind’ – a shared consciousness, a way of thinking about things that is more than shared attitudes. Such communities also share rituals and traditions and they have a sense of moral responsibility to the community as a whole and to the individual members. This sense of morality can in times of threat, protect the community and produce collective action. A community forms because of certain shared traditions, rituals, behavior patterns or values. According to Muniz and Schau (2005) religious a ffiliation are vital to brand communities. Consumer behavior thus depends on the individual society and its characteristics. The character and structure of the communities are further affected by the commercial and mass-mediated ethos. Brand communities are different from subcultures although they may have some commonalities. The meaning that sub-cultures create stand in opposition or indifference to the meanings that is generally accepted. Brand communities are united by their commonalities and they are communities of limited liability (Muniz, Albert and O’Guinn). They are legitimate forms of community
