Juvenile Gangs in America Term Paper Example | Topics and Well Written Essays - 2250 words

Juvenile Gangs in America - Term Paper Example Gangs are found in both urban and rural areas. Adult criminal offenders emanate from gangs at an early age and recruit their members from the gangs. Gangs should be diverted into constructive activities where they can positively utilize their energy and honestly make money instead of using criminal means. Juvenile Gangs in America The case of the young gang member is a sad one as instead of having a fruitful youth they waste themselves in burglary, muggings, robbery, gang wars, drug abuse and drug sale according to Franzese, Covey and Menard (2006). Both males and females engage in gang activities and may find themselves in juvenile jails at an early age owing to criminal activities in which they engage. This paper aims to study Juvenile gangs in America; types of Juvenile gangs, what causes them and the effect they have on society and the crimes they engage in, in the United States. The youth are constantly striving to seek for answers as to who they really are. They are looking to define their character, their objectives and pathways in life. This is probably the reason why gangs are constituted mainly of the youth; people lost looking to find their footing in life and in society. Law enforcers define gangs in a simple way as organized groups that join together for the common objective of committing criminal offences (Barrows and Huff, 2009). Barrows and Huff also state that gangs are strongly glued together, very organized, secretive and violent; a group that is a fast growing great threat to society. They also look to find where they feel safe and secure and a place where they feel dignified. Gangs offer this forum and make the young person feel comfortable and protected. The disadvantage with gangs, even as they offer this homely feel for the youth, is that they offer the wrong advice; a tool of menace instead of positive development. United States has experienced a rebirth of gangs and crimes perpetuated by gangs over the last twenty years (Katz and Webb, 2006). Johnson (2004) submits that there are various types of youth gangs in the streets of United States. Scavengers at times referred to as wanna-be gangs are mainly consisted of whites from the suburbs whose main purpose is to bully and threaten other youngsters. Hispanic gangs, on the other hand, named as territorial gangs gather respect. African American gangs and a few Hispanic gangs called hardcore gangs endeavor to generate money by all means and kick out rival groups through violent. Members of a particular gang share various things such as ambition, devoutness and even backgrounds. The juvenile gang menace is mistaken to be uniquely American but it is a characteristic of many other nations and continents too as state by Siegel and Welsh (2011). The UK is a good example of a state disturbed by juvenile gangs and specifically the capital, London. Though there are many kinds of Juvenile gangs in the US, they tend to share similar characteristics. Such characteristics are; th ey are made up of youths, they protect particular territories mainly in the streets and they are immersed in criminal activities of all sorts. Gangs in the United States exist in all cities and members of gangs tend to evolve into leaders of organized crime settings (Finley, 2007). Young juvenile gang members are often trained by adults and are taught many things among them particular ways of

Managed Care Essay Example | Topics and Well Written Essays - 3000 words

Managed Care - Essay Example emerged in this modern world and the employers in the present day context get involved in making as well as executing an effective plan with utmost focus on paying premiums. These premiums are paid by the workers in the form of deductibles, copayments as well as through contribution. It has been apparently recognized that this changed system of healthcare has transformed the investment pattern of the employees. In the year 2013, highest number of employees was recorded to be enrolling in the Preferred Provider Organization (PPO) plans. The same has been illustrated in the form of the following chart: Managed care has proved its dominance in providing â€Å"qualified health plans† with the aid of different health insurance organizations. Specially mentioning, there is a need to follow the rules that are provided under the Affordable Care Act. The ACA prescribed system of medical loss is noted to be limiting the percentage of premium revenue for enhancing its use for administration, marketing as well as attaining maximum profit. However, to increase the transparency within the system, more regulations are required to be incorporated by the respective government. To increase the competition within the domain of healthcare aid, there are various additional developments being initiated to incorporate within the domain of healthcare based operations. This competitive edge is being developed with the notion to enhance the control over the premium rate fluctuations (Shi & Singh, 2011). ACA visualizes that Consumer Operated and Oriented Plans (CO-OPs) will be developed based on finances received from the federal government. This type of plans is available in small numbers within the US Medicaid services. CO-OPs started operating as nonprofit making organizations following the developments such as the Health Maintenance Organization (HMO) and PPO. CO-OPs are even structured based on standard models of such organizations that have been already active within Medicaid

The Moral Issues Of The Animal Testing Essay Example | Topics and Well Written Essays - 750 words

The Moral Issues Of The Animal Testing - Essay Example The debates stemming from animal rights are one of the major issues being discussed in medical symposiums and environmentalists. In my opinion, animal testing is not justified. Animal testing is not only morally wrong, but also the results of the experiments are not hundred percent accurate. It has been estimated that over 50 to 100 million vertebrate animals are used in experiments and trials; the figure of animals used in testing is even greater. The animals that have not been weaned and invertebrates are not included in the aforementioned figure. A major fraction of the animals that have been tested upon is killed. Although many of the researchers are being conducted on the safety of animals, it is not justified to use animals for the purpose of human safety. It is not off beam to know more about animals and to study them in more detail like there is nothing wrong in furthering our research about planetary bodies. However, it needs to be noted that the researchers being done on an imals can be misleading. It is with experience and researches conducted in the past that have made us realize that some drugs may fail to elicit the same response as they did in animals. It is such failed researchers that attest to the fact that animals are different from humans. Using rats for cancer research was one such example where torturing animals were the sake of human good was pointless (Pakistan Politics Journal). Scientists had resorted to rats as test subjects until 1993 when it was reported that the genetic makeup of the rats renders them vulnerable to cancer, and so research on them ca never yield accurate results. Cohen adheres to the view that animals are not like humans and this is why he believes that they can be used for animal testing (94). Right is fundamentally a claim that one individual asserts over the other. A right encompasses the elements such as who holds the right and to whom it is against.

India- Socio- Cultural Variables Essay Example | Topics and Well Written Essays - 750 words

India- Socio- Cultural Variables - Essay Example During the last century while the world's population grew three fold, India population grew four fold. This increase could have been much more if the government of India had not adopted population control measures for the last three decades. Spread over an area of around 3.3 million square kilometers, it is the seventh largest country in the world. India is the world's largest democracy with a population nearly four times that of the United States. Indian government has adopted the British Parliamentary system with valuable inputs from USA and European governments. Population density is an indication of population concentration. It is defined as the number of persons per square kilometer. Official census figures of government of India indicate that the population density of India in 2001 was 324 persons per square kilometer, which indicates that now 57 more people live in a square kilometer area in the country than the number that lived a decade ago. In 1901 the density of India was as low as 77 and this steadily increased from to reach 324 in 2001. The cause of worry for the Indian government is that this increase is not matched equally by the increase in healthy food, diet and other resources. Per capita income in India is approx. INR 12500 i.e. approx. $290. Contrast this with the per capita income of US, which is more than $40000, while US population is less than one fourth of India. Such disturbing figures give rise to discontentment amongst the masses. If we look towards India as a market, it is indeed a very attractive market. Because, market needs customers - the more the merrier. Of late this market of more than a Billion people has been attracting MNCs in good numbers. If per capita income is less here then cost of production is also less so goods and services are priced accordingly. Indian government is also in the facilitating mode to Investments from abroad. Therefore from the investment point of view I'd give it 7 out of 10. Age Profile and Employment Scenario: Though official poverty figures have been coming down sharply e.g. the figures indicate that poverty ratio came down from 36% in 1993-94 to 26% in 1999-2000, yet a large number of educated youth remain unemployed. The population of India is estimated to be 1.4 billion (1,400 million) by the year 2025, and youth will form the majority of the population. With this problem in sight, the tenth five-year plan targets that gainful and high-quality employment will be provided to the majority. Unlike some of its neighbors, education level in India has been quite good. Engineering and Management graduates from Indian Institutions have left their mark in many international companies. The Pentium chip of Intel had the brain of an Indian. Majority of the H1B visa holders in USA are from India. The recent trend of outsourcing ITES towards Indian subcontinent is the testimony for the education level and technical capability of Indian youth. From an Investment point of view, I feel Indian youth wil l prove very helpful. I'll give 9 points out of 10. Entrepreneurship culture Historically, India is not much known as the nation of venture capitalists. Indians preferred to play safe. But the IT bug seems to have converted them into venture capitalists as well. For example, Hotmail was the brainchild of a 25 year old Indian youth Sabeer Bhatia. He made billions by selling it to

IT Project Management Ch7 Assignment Example | Topics and Well Written Essays - 500 words

IT Project Management Ch7 - Assignment Example The main benefit of using its cost management feature is that it allows project managers to manage all the project related information at a single place. For instance, all the project related information such as resources, activities, schedule and costs can be managed in a single application at the single location. As a result, it becomes easy for them to integrate project activities with associated cost and schedule (Schaffhauser, 2010; Microsoft Corporation, 2015; Schwalbe, 2012). Every project manager uses a specific project management tool in order to manage their project management activities. For the cost management, they use specific criteria and some firms have their own software tools that allow them to calculate costs according to their available resources. In some cases, cost estimates are developed and maintained separately from the project plan. Though, MS Project 2010 encompasses all the features that are necessary to maintain a complete project cost management process, but it is still a new component for the majority of project managers, and it can take some time to get complete expertise (Schwalbe, 2012). The project completion opens a door for learning by measuring the performance and improving on the basis of mistakes. To evaluate the performance of any project, the Earned Value Management is quite a significant evaluation practice used in project management (Schwalbe, 2012). A study conducted by Dr. Song that is sponsored by the PMI (Project Management Institute) and CPM (College of Performance Management), is purposed at assisting the project managers to understand and measure the extent of practicing the Earned Value Management technique in project management as well as its practitioners’ base. This study’s important aspect is to deliver a cross sectional perspective of most of the recent EVM practices by surveying more than 600 project management experts. For getting a more useful and practical insight

The Sukhoi Superjet Essay Example for Free

The Sukhoi Superjet Essay The Sukhoi Superjet 100 is fly-by-wire regional jet with 75 up to 95 seats[1]. Since the jet industry faces many competitors, it is an important action to design an effective marketing strategy, which includes a SWOT analysis. Strengths: *Equipped with two Saturn/SNECMA PowerJet SaM146 turbofans1 *has   10-15% lower operation costs than its competitors, which areEmbraer E-Jets and   the Bombardier CSeries programs1. This will enable Sukhoi Superjet 100 to sell at a lower price and hence making it more affordable. As a result higher sales, profits and market share occurs. *has a wider cabin and thus offers more comfort1. Not only is it cheaper but also more comfortable, hence establishing a competitive advantage for the Superjet 100. *The Superjet 100 airliner family is being developed based on the principle of maximum standardization of frame assemblies and systems1. This will enable Superjet 100 to perform more economically while keeping expenditures at a rational level. *The aerodynamics and design of the aircraft of the family are based on proven advanced technology to minimize technical risks at the stage of design, testing and operation1. A higher security attracts more satisfied customers, which could lead to positive publicity and thus higher demand and value of its shares. Weaknesses: *Completion of the deal to order 25 Sukhoi Superjet 100 with Dalivia was delayed2. Dalivia could consider to buy from its competitors, hence this would provide Superjet’s 100 competitors with a competitive advantage, sales, profits and market share. Opportunities: *Air France3, Lufthansa4, SAS5, Iberia6, UTair Aviation, MDLR Airlines and Merpati Nusantara Airlines7 are potential customers. *Malev Hungarian Airlines and Scandinavian Airlines System are reported to finalize their orders and an Indonesian airline is reported to be the airliner1. *Alliance Air of India has also showed interest in the Sukhoi Superjet 1008. *Armavia signed a multimillion-dollar agreement to buy four Sukhoi Superjet 100 planes for regional flights1. These orders will offer Superjet 100 to reach more customers, since if passengers feel satisfied; hence it could lead to repeat sales an word-of-mouth advertising, which then creates higher demand, sales and profits; hence airlines will then purchase more of the Sukhoi Superjet 100. Threats: *Its competitors Embraer and Bombardier offer much more comprehensive after-sales and maintenance network9. After-sales service is important for maximizing customer satisfaction and it can also lead to having a competitive advantage. In fact a research showed that 1 dissatisfied customer tells 11 others who then 5 others10, which would worsen the image of the product quickly, and thus lower sales, profits and market share occurs.

Online Self Testing for Real Time Systems

Online Self Testing for Real Time Systems A Survey on Different Architectures Used in Online Self Testing for Real Time Systems I.ABSTRACT On-line self-testing is the solution for detecting permanent and intermittent faults for non safety critical and real-time embedded multiprocessors. This paper basically describes the three scheduling and allocation policies for on-line self-testing. Keywords-components: MPSoC, On-line self-testing, DSM technology II.INTRODUCTION Real-time systems are very important parts of our life now a day to day. In the last few decades, we have been studied the time aspect of computations. But in recent years it has increase exponentially among the researchers and research school. There has been an eye catching growth in the count of real-time systems. Being used in domestic and industry production. So we can say that real-time system is a system which not only depends upon the correctness of the result of the system but also on the time at which the result is produced. The example of the real-time system can be given as the chemical and nuclear plant control, space mission, flight control systems, military systems, telecommunications; multimedia systems and so on all make use of real-time technologies. Testing is a fundamental step in any development process. It consists in applying a set of experiments to a system (system under test − SUT), with multiple aims, from checking correct functionality to measuring performance. In this paper, we are interested in so-called  black-box conformance testing, where the aim is to check conformance of the SUT to a given specification. The SUT is a â€Å"black box† in the sense that we do not have a model of it, thus, can only rely on its observable input/output behavior. Real time is measured by quantitative use of clock (real clock)[1].Whenever we quantify time by using the real clock we use real time. A system is called real time system when we need quantitative expression of time to describe the behavior of the used system. In our daily lives, we rely on systems that have underlying temporal constraints including avionic control systems, medical devices, network processors, digital video recording devices, and many other systems and devices. In each of these systems there is a potential penalty or consequence associated with the violation of a temporal constraint. a. ONLINE SELF TESTING Online self-testing is the most cost-effective technique which is used to ensure correct operation for microprocessor-based systems in the field and also improves their dependability in the presence of failures caused by components aging. DSM Technologies Deep submicron technology means, the use of transistors of smaller size with faster switching rates[2]. As we know from Moores law the size of transistors are doubled by every year in a system, the technology has to fit those inc in transistors in small area with better performance and low-power[4]. III. Different Architectures used in Online Self Testing in Real Time Systems. 1.The Architecture of the DIVA Processing In Memory Chip The DIVA system architecture was specially designed to support a smooth migration path for application software by integrating PIMs into conventional systems as seamlessly as possible. DIVA PIMs resemble, at their interfaces, commercial DRAMs, enabling PIM memory to be accessed by host software either as smart memory coprocessors or as conventional memory[2]. A separate memory to memory interconnect enables communication between memories without involving the host processor. PIM Array PIM to PIM Interconnect Fig.1: DIVA Architecture A parcel is closely related to an active message as it is a relatively lightweight communication mechanism containing a reference to a function to be invoked when the parcel is received. Parcels are transmitted through a separate PIM to PIM interconnect to enable communication without interfering with host memory traffic. This interconnect must support the dense packing requirement of memory devices and allow the addition or removal of devices from system. Each DIVA PIM chip is a VLSI memory device augmented with general purpose computing and communication hardware[3]. Although a PIM may consist of multiple nodes, each of which are primarily comprised of few megabyte of memory and a node processor. 2. Chip Multiprocessor Architecture (CMP Architecture) Chip multiprocessors are also called as multi-core microprocessors or CMPs for short ,these are now the only way to build high-performance microprocessors, for a number of reasons[6]. limiting acceptance of CMPs in some types of systems. Fig.2: The above figure shows the CMP Architecture[6] 3. SCMP Architecture: An Asymmetric Multiprocessor System-on-Chip Future systems will have to support multiple and concurrent dynamic compute-intensive applications, while respecting real-time and energy consumption constraints. Within this framework, an architecture, named SCMP has been presented[5]. This asymmetric multiprocessor can support dynamic migration and preemption of tasks, thanks to a concurrent control of tasks, while offering a specific data sharing solution. Its tasks are controlled by a dedicated HW-RTOS that allows online scheduling of independent real-time and non real time tasks. By incorporating a connected component labelling algorithm into this platform, we have been able to measure its benefits for real-time and dynamic image processing. In response to an ever increasing demand for computational efficiency, the performance of embedded system architectures have improved constantly over the years. This has been made possible through fewer gates per pipeline stage, deeper pipelines, better circuit designs, faster transistors with new manufacturing processes, and enhanced instruction level or data-level parallelism (ILP or DLP)[7]. An increase in the level of parallelism requires the integration of larger cache memories and more sophisticated branch prediction systems. It therefore has a negative impact on the transistors’ efficiency, since the part of these that performs computations is being gradually reduced. Switching time and transistor size are also reaching their minimum limits. The SCMP architecture has a CMP structure and uses migration and fast preemption mechanisms to eliminate idle execution slots. This means bigger switching penalties, it ensures greater flexibility and reactivity for real-time systems. Programming Model The programming model for the SCMP architecture is specifically adapted to dynamic applications and global scheduling methods. The proposed programming model is based on the explicit separation of the control and the computation parts. Computation tasks and the control task are extracted from the application, so as each task is a standalone program. The control task handles the computation task scheduling and other control functionalities, like synchronizations and shared resource management for instance. Each embedded application can be divided into a set of independent threads, from which explicit execution dependencies are extracted. Each thread can in turn be divided into a finite set of tasks. The greater the number of independent and parallel tasks are extracted, the more the application can be accelerated at runtime. Fig3: SCMP Processing As shown in Figure 9, the SCMP architecture is made of multiple PEs and I/O controllers. This architecture is designed to provide real-time guarantees, while optimizing resource utilization and energy consumption. The next section describes execution of applications in a SCMP architecture. When the OSoC receives an execution order of an application, its Petri Net representation is built into the Task Execution and Synchronization Management Unit (TSMU) of the OSoC. Then, the execution and configuration demands are sent to the Selection unit according to application status. They contain all of active tasks that can be executed and of coming active tasks that can be prefetched. Scheduling of all active tasks must then incorporate the tasks for the newly loaded application. If a non-configured task is ready and waiting for its execution, or a free resource is available, the PE and Memory Allocation Unit sends a configuration primitive to the Configuration Unit. Fig4:SCMP Architecture[5] Table Of Comparison   Ã‚   Name Of The Paper Year of Publication Author Limits The Architecture of the DIVA Processing In Memory Chip 2002 Jeff Draper, Jacqueline Chame, Mary Hall, Craig Steele, Tim Barrett, Jeff LaCoss, John Granacki, Jaewook Shin, Chun Chen, Chang Woo Kang, Ihn Kim, Gokhan Daglikoca This paper has described a detailed description of DIVA PIM Architecture. This paper having some issues for exploiting memory bandwidth, particularly the memory interface and controller, instruction set features for fine grained parallel operation, and mechanism for address translation. Chip Multiprocessor Architecture: Techniques to Improve Throughput and Latency 2007 KunleOlukotun, LanceHammond, James Laudon This work provides a solid foundation for future exploration in the area of defect-tolerant design. We plan to investigate the use of spare components, based on wearout profiles to provide more sparing for the most vulnerable components. Further, a CMP switch is only a first step toward the overreaching goal of designing a defect-tolerant CMP system. SCMP Architecture: An Asymmetric Multiprocessor System on-Chip for Dynamic Applications 2010 NicolasVentroux, Raphael David The new architecture, which has been called SCMP, consists of a hardware real-time operating system accelerator (HW-RTOS), and multiple computing, memory, and input/output resources. The overhead due to control and execution management is limited by our highly efficient task and data sharing management scheme, despite of using a centralized control. Future works will focus on the development of tools to ease the programmation of the SCMP architecture. Conclusion We have done a survey how on-line self-testing can be controlled in a real-time embedded multiprocessor for dynamic but non safety critical applications using different architectures. We analyzed the impact of three on-line self-testing architectures in terms of performance penalty and fault detection probability. As long as the architecture load remains under a certain threshold, the performance penalty is low and an aggressive self test policy, as proposed in can be applied to [8] D. Gizopoulos et al., Systematic Software-Based Self -Test for Pipelined Processors, Trans. on Vlsi Sys., vol. 16, pp. 1441-1453, 2008. such architecture. Otherwise, on-line self-testing should consider the scheduling decision for mitigating the overhead in detriment to fault detection probability. It was shown that a policy that periodically applies a test to each processor in a way that accounts for the idle states of processors, the test history and the task priority offers a good trade-off between the performance and fault detection probability. However, the principle and methodology can be generalized to other multiprocessor architectures. References [1] R. Mall. â€Å"Real-time system†: Theory and practice.
