The Two Dominant Political Parties in the United States of America Essay

The Two Dominant Political Parties in the United States of America - Essay Example The federalist also insisted that the government should be run by "best people" or the elite and not by the common people. They supported the executive branch of the government. The Republicans wanted strict and inflexible interpretation of the institution and opposed central government. They proposed that the government lessen its intervention to economy and give the power to the state because they desired more involvement of the people. They also support legislature to formulate laws in governing the populace. Federalists admired the British and wanted to copy the aristocracy of Great Britain. The Republicans favored France. The Federalists' suppression of freedom of press and speech was strongly opposed by the Republicans. There were some similarities of these two political parties. To promote their policies and ideologies, the Federalists created Gazette of the United States and the Republican set up the National Gazette. This increased the involvement of the people, dividing further the Americans. Both parties supported foreign countries: the Federalist for Great Britain and the Republican for France.

CRJS 205 Introduction to Criminal Law - Essay Example The client in this context is a victim of a sexual assault and she can sue the offender. However, the decisions (jail term and damages) that will be made by the jury in the criminal and civil courts will depend on the state’s statutory rape laws. When a client decides not sue the offender, the sex crime kit is usually kept for a certain period within which the victim can report to the law enforcement. In West Virginia, the sex crime kit or the evidence is stored for 18 months if the victim does not initiate an investigation. However, after 18 months the evidence is destroyed or used for research purposes or used for training; this is done after the removal of identifying information (West Virginia Foundation for Rape Information and Services [WV-FRIS], 2008). It is important to note that evidence is required if the victim desires to sue the offender. If the client has evidence, she can sue the offender for sexual assault of the first degree if sexual intercourse and bodily harm were inflicted or sexual assault of the second degree is only sexual intercourse occurred. If found guilty of first-degree sexual assault, the offender can be â€Å"imprisoned in the penitentiary between 15 and 35 years or imprisoned in the penitentiary between 15 and 35 years and fined between $1,000 and $10,000† (The Lectric Law Library, 2012). If found guilty of second-degree sexual assault, the offender can be jailed in the prison between 10 and 25 years or jailed in the prison between 10 and 25 years accompanied with a fine between $1,000 and $10,000 (The Lectric Law Library, 2012). In addition to criminal prosecution, the victim can file a civil suit with the help of a private attorney in a Civil Court. If the victim wins the civil lawsuit, the court orders the attacker to pay money for the damages caused (the damages include loss of income, suffering, pain, and medical expenses). Punitive damages are also available if the victim does

William Burroughs’s Fiction Essay Example for Free

William Burroughs’s Fiction Essay This paper will argue that William Burroughs’s fiction is directed at subverting and deconstructing the dominant social order and mainstream conventions and social practices. In such novels as The Western Lands (1987), The Soft Machine (1961), The Ticket that Exploded (1962) or The Nova Express (1964) the author constructs full-fledged literary outlaws – gangsters, conmen, etc. – in order to epitomize the forceful and illegitimate ways in which ideas, opinions or the entire reality can be imposed on the ostracized other. Therefore, William Burroughs’ novels also offer a reflection of American capitalist society and its unorthodox power relations. This theme will be investigated in the novel in light of Guy Debord’s The Society of the Spectacle which discusses the specular character of the capital society and the gaps between reality and representation. In his article on Burroughs, Frederick M. Dolan argues that   in the writer’s novels, all the rogue figures â€Å"control others by mastering the art of producing vivid and convincing representations, exploiting the naà ¯ve, metaphysical urge to believe that when language appears most meaningful, it has because it has established a referential relationship to the world† (Dolan, p. 536). This is precisely what the â€Å"society of the spectacle† is attempting to achieve by superimposing the show of capitalist order on everyday reality. Burroughs was also very interested in showing the distorting power of language and the ways in which reality can be manipulated because of this. From this perspective, Jacques Derrida’s book, Of Grammatology, will be particularly useful in the analysis of Burroughs’s language treatment and of the ways in which the writer’s deliberate foregrounding of the gaps between signifier and signified undermine the capitalist social order and ingrained thought-mechanisms. Burroughs denounces contemporary man as automaton, as passive receiver of ideology. Works Consulted: Burroughs, William S. The ticket that exploded. Grove Press, 1987.

Islamic Feminism: An overview

Islamic Feminism: An overview Introduction Feminism is a secular ideology and Islam today rests on fundamentalist foundations. Those who advocate that feminist projects be conducted within an Islamic framework have clearly despaired of secular options for change without considering how have elaborated Lilas argument against the possibility of the coexistence of Islam and feminism because it explains the anxiety many Muslim women public intellectuals, including Chandra Talpade (2003), Jasmine (2004), and Martin (2003), feel as they watch the Taliban taking away womens rights in Afghanistan, the Algerian Front Islamique de Salut targeting women intellectuals, the fundamentalist Sudanese government oppressing its women. Many are sure that compromise with such a religion is fatal. Some women are joining religious groups despite their gender conservatism. Others are fighting these same groups, fearing the dangerous chemistry of politics and religion. Whether through or against religion they are choosing to become part of the struggle for a better world. The question many pose to women who voluntarily Islamize is: Do they accept their communities reactionary norms or do they appropriate and in the process subvert them? If there are some who can be considered feminists according to my definition of the term, how do they adapt their convictions that women have certain rights with the perceived need to subsume them to the community interest? How will the ways in which they position themselves to assert responsibility for the construction of their own, new religious identity change the face of Islam? How does participation in jihad allow for feminist activism? These are the questions which are imposed and discussed by Amina Wadud, Badran (1995), Hamid (2006), Saba ( 2005), Lila (2002) and other writers in their respective books and articles. Feminism according to Holy Quran The Quran is unequivocally opposed to gender equality, and the Sharia is not compatible with the principles of equality of human beings (Afshar, 1996, p.122). Despite its growing currency throughout the Muslim world, Lila asserts that Islamic feminism has no coherent, self-identified and/or easily identifiable ideology or movement. Those who advocate its utility as a concept and a marker for a specific brand of feminism are not women from within Muslim societies but rather diasporic feminist academics and researchers of Muslim background living and working in the West (126). These women she later characterizes as exceptionally forgiving, postmodern relativist feminists in the West whose indigenized and exotic form of Western feminism excludes core ideas of legal and social equity, sexual democracy and womens control over their sexuality (146). The attitudes to Islamic feminism span the gamut of leftists like herself who reject its possibility because they consider divine laws inherently hostile toward feminism, to those who posit that feminism within an Islamic framework is the only culturally sound and effective strategy for the regions womens movement (134). The latter group may include secularists overwhelmed by the political and discursive influence of Islamic fundamentalism (134). Here lies the major problem in Lilas argument: she confounds Islam and Islamic fundamentalism, as though the two were the same. This affirmation, she dramatically asserts, relies on twisting facts or distorting realities, ignoring or hiding that which should be clear (135). Her very real fear is that to celebrate Islamic feminism is to highlight only one of the many forms of identity available to Middle Eastern women, obscuring ways that identity is asserted or reclaimed, overshadowing forms of struggle outside religious practices and silencing the secular voices which are still raised against the regions stifling Islamification policies (137-38). An Anti-Modern Feminist Perspective A considerably different perspective is presented in Anouar Majids â€Å"The Politics of Feminism in Islam.† Majid is wary of the dangers of imposing Western feminist traditions on non-Western cultures and attempts therefore to recuperate a feminist tradition within traditional Islamic culture, though he is not entirely successful in doing so. Majid recognizes that the problems women face in Islamic societies cannot be divorced from European colonialism. For Majid, the political and economic structures that have resulted from independence from European domination have not emancipated the poor (341). He feels that nationalist elites have established Eurocentric models of government, namely nation-states (342, n. 17). For Majid, representations of Islamic culture as undemocratic and patriarchal reify the history of Muslim culture and downplay the impact of imperialism on gender relations in Islamic countries (349). Majid finds that a major problem in attempting to develop Islamic feminist perspectives is the difficulty of overcoming the Western and often Orientalist biases that pervade feminist thought. These biases include a dehistoricised notion of human rights and â€Å"an implicit acceptance of the bourgeois political apparatus as a reliable mechanism for negotiating the grievances of the exploited† (339). Western feminism cannot be readily separated from hostility to Islamic culture, according to Majid. To illustrate the point, he cites the example of upper-class Islamic women who have sometimes embraced Western feminist values and in the process â€Å"condemned native customs as backward, proclaimed the superiority of the West, and uncompromisingly equated unveiling with liberation† (338). Females in Islam Even though women may have high-status professional jobs and make important decisions in the course of the day, and even though Islamic sharia insists that women have the right to keep their income, it appears that husbands continue to control the decisions concerning expenditures. The husband is pivotal in allowing his wife to work in the interest of the welfare of the family, he is also the final arbiter in defining what constitutes that welfare. In many instances, while accepting that she may work outside the home, he will not allow her to participate in public events. As already noted, Oven the power of the constitutions of various countries affirming the determination of the sharia that men are in charge of women, there is little chance for change in the foreseeable future. Modernization and urbanization, however, have brought about certain changes in family life. One is a preference for nuclear families. This has altered the traditional power of the mother-in-law which has been undermined by the new system. Instead of being a guest in her mother-in-laws home, the bride gets to be in charge of her own household. But, if she also has to go out to work in order to maintain private residence, her workload is doubled. In addition, the change in housing design from the traditional open courtyard with a garden and opening to the sky to the small apartment has confined the woman and restricted her contact with other members of the family as well as with nature. If her husband restricts her going out, she feels imprisoned and lacks contact with friends and intimate relations. Zine identifies what she sees as the roles for women, determined by the tripartite class structure of Arab society: the working class, the middle class, and the upper class. In the working class, she says, a sharp distinction is made between feminine and masculine characteristics (Zine, 2006, p.19). Conclusion One of the themes that emerges from contemporary writing about Muslim women is that of woman as victim of the experience of oppression in developing countries. The oppression is not unique to the Arab context but is a consequence of disempowerment and feelings of impotence. The condition of the woman serves to demonstrate the extremes of disempowerment. She has become the projection of the inadequacy of the society, shackled with the burden of failure and weakness. Her inherent worth is devalued in relation to her physique, intellect, gender, productivity, and status. At the same time, her role as mother is symbolically elevated. Islam provides security and equivalence to the females and it has made many laws which secures the importance of females in this male dominant world. References Abu-Lughod, Lila 2002.

To facilitate the discussion smoking as a public health issue has been chosen. The holistic impact smoking have on the wellbeing of an individual will be explored. The stage of change model and the Healthy Lives (2010) policy will be explored in relation to smoking. The rationale for choosing this topic is because smoking is an important public health issue. The smoke is very toxic to every human tissue it touches on its way into, through and out of the smoker’s body (Ewles 2005). Smoking is considered as a health hazard because Tobacco smoke contains nicotine, a poisonous alkaloid, and other harmful substances such as carbon monoxide, acrolein, ammonia and tars.Gorvenment initiatives like the Public Health White Paper, choosing health; Making Choices Easier (DH 2004) will be addressed. The nurse’s role and other professions involved will be highlighted .Confidentiality shall be maintained throughout this essay as prescribed by the Nursing and Midwifery Council (2008). The impact of tobacco smoking on public health extends beyond the direct effects on the individual smoker and their personal health, plus taking into account the effect on their economic, environmental and social effects (Ewles 2005).). Smoking harms nearly every org an of the body thereby causing many diseases, reducing quality of life and life expectancy. Also it has been estimated that in England, 364,000 patients are admitted to NHS hospitals each year due to smoking related diseases which translates into about 7,000 hospital admission per week and 1,000 admissions per day (ASH 2006). In the UK, smoking causes about a fifth of all deaths, approximately 114,000 each year, most of which are premature with an average of 21 years early (Ewles 2005). According to Peto et. al. (2003) cited in Ewles (2005), most premature deaths caused by smoking are Lung and coronary cancer, chronic obstructive heart diseases and coronary heart diseases with 42800, 29100 and 30600 deaths respectively every year. In addition, smoking is known to also bring increased risk of many debilitating conditions like impotence, infertility, gum disease, asthma and psoriasis (Ewles 2005). Research has also shown that non-smokers are put at risk by exposure to other peopleâ₠¬â„¢s smoke which is known as passive or involuntary smoking and is also referred to as second-hand smoke (SHS) or environmental tobacco smoke (ETS) (Cancer Research 2009). According to the Oxford Medical Companion (1994) cited in the WHO report on the global tobacco epidemic 2008, â€Å"tobacco is the only legally available consumer product which kills people when it is used entirely as intended†. Tobacco is the leading preventable cause of death in the World which causes one in ten deaths among adults worldwide and in 2005, tobacco caused about 5.4million deaths, an average of one death every six second Certain behaviors have been labeled as risky behaviors associated with negative health outcomes among which smoking is and which has been the subject of UK national health strategies (Naidoo Wills 2005). Smoking causes about one fifth of all deaths in the UK, most of which are premature and has hugely significant impacts on the wider environment and community through causing air pollution, fires, litter and environmental damage (Ewles 2005). Prevalence of smoking among the low paid groups has been observed to be twice those of the affluent groups because of the great difficulty people in the less affluent groups experience in stopping smoking (Ewles 2005). Tobacco smoking is also widely recognized as a cause of health inequality in the UK because it is common among the deprived groups and also compromises the already poorer health of deprived population such as those that fall within the marginalized groups. Examples are people with mental problems and prisoners, who are more likely to smoke and less likely to have access to mainstream smoking cessation services (Ewles 2005). The Index of multiple deprivation ranks areas from the most deprived to the least deprived and the odds of smoking increases as deprivation in the area increases (The NHS Information centre 2008). Children smoke for all sorts of reasons. Some smoke to show their independence, others because their friends do while some smoke because adults tell them not to and others do smoke to follow the example of role models. There is no single cause. Parents, brothers and sisters who smoke are a powerful influence. Also is the way it is been advertised and the tobacco companies sponsor sport which makes children want to try it (DH 1998). The problems of smoking during pregnancy are closely related to health inequalities between those in need and the most advantaged. Women with partners in manual groups are more likely to smoke during pregnancy than those with partners in non-manual groups: 26 per cent of women with partners in manual groups smoke during pregnancy, compared with 12 per cent with partners doing non-manual work (DH 1998). Health promotion is a complex activity and is difficult to define. Davies and Macdowall (2006) describe health promotion as â€Å"any strategy or intervention that is designed to improve the health of individuals and its population†. However perhaps one of the most recognized definitions is that of the World Health Organization’s who describes health promotion as â€Å"a process of enabling people to increase control over their health and its determinants, and thereby improve their health (WHO 1986). If we look at this in relation to the nurse’s role in smoking cessation and giving advice to a patient, this can be seen as a positive concept in that with the availability of information together with support, the patient is then able to make an informed decision, thus creating empowerment and an element of self control. Bright (1997) supports this notion suggesting that empowerment is created when accurate information and knowledgeable advice is given, thus aiding the development of personal skills and self esteem. A vital component of health promotion is health education which aims to change behavior by providing people with the knowledge and skills they require to make healthier decisions and enable them to fulfill their potential. Healthy Lives Healthy People (2010) highlight the vital role nurses play in the delivery of health promotion with particular attention on prevention at primary and secondary levels.Nurses have a wealth of skills and knowledge and use this knowledge to empower people to make lifestyle changes and choices. This encourages people to take charge of their own health and to increase feelings of personal autonomy (Christensen 2006). Smoking is one of the biggest threats to public health, therefore nurses are in a prime position to help people to quit by offering encouragement, provide information and refer to smoking cessation services. In 2010 the white paper Healthy Live Healthy People set out the government long term policy for improving public health and in 2011 a new tobacco control plan was published (Department of Health 2011). The Whitepaper Healthy Life Healthy People set out a range of measures aimed at preventing people from starting to smoke and helping them to stop, such as banning cigarettes advertising on billboards, in size and action on tobacco intensified (DH, 2011). WHO defines health promotion a process of enabling people to increase control over and to improve, their health. It implies that the ideology moves beyond a focus on individual behavior towards a wide range of social and environmental interventions. Naidoo and Wills (2010), states ‘health promotion is based on theories about what influences people’s health and what are effective interventions or strategies to improve health.

Society’s Neglect of the Homeless Essay example -- Argumentative Persu

Society’s Neglect of the Homeless There is a serious problem with the way homeless people are treated. They are not treated as any normal human being is treated. The homeless have been dubbed the outcasts of society and receive practically no assistance from the government. Where is the consideration for these people? Are homeless people considered less than human? Why is it so hard to give a helping hand to somebody who is in need? Is society becoming too self-absorbed or are homeless people just transient to the rest of society? Society does not want to be bothered with the problems of inhumane people living on the streets, when there are enough problems within it. There should be no reason for people to worry about the problems of others. The government is mainly responsible for the welfare of all the people living in its area. In society homeless people are on the bottom of a prioritized list. That is why homeless people are categorized as mentally ill. Nobody wants to deal with the problem, so they make an excuse of a homeless person being on the street because of ment...

The Android OS is the name of the Linux based operating system owned by Google and supported by the Open Handset Alliance. Android is used as an operating system for devices such as cell phones, tablets and netbooks. Google bought the original developer of the software, Android Inc. , in 2005. Android's kernel (core of the OS) was derived from Linux but has been modified by Google developers. Android is also open source, which means developers can customize the OS for different phones and applications. This is why different phones may have different looking graphical interfaces and features even though they are running the same OS. Android OS is completely open source, which means that developers can use the core OS functions to develop applications, unlike iphone OS which is a closed system. About The version history of the Android operating system began with the release of version 1. 0 in September 2008. Android is a mobile operating system developed by Google and the Open Handset Alliance. Android has seen a number of updates since its original release. These updates to the base operating system typically fix bugs and add new features. Generally, each version is developed under a code name based on a dessert item. The code names were released in alphabetic order: Cupcake, Donut, Eclair, Froyo, Gingerbread, Honeycomb, and Ice Cream Sandwich. Like Apple's Appstore, Google opened its Android market, allowing the apps developers to publish their apps without any restrictions. Unlike Apple's Appstore, Google Android market does not have any restrictions for third party development and will not run an apps approval system. Android is an open source platform. The entire stack, from low-level Linux modules all the way to native libraries, and from the application framework to complete applications, is totally open. More so, Android is licensed under business-friendly licenses (Apache/MIT) so that others can freely extend it and use it for variety of purposes. Even some third-party open source libraries that were brought into the Android stack were rewritten under new license terms. Therefore, every developer has access to the entire platform source code. There are several advantages of the Android OS for developers, besides the fact that it’s completely open source, let’s mention a few: Advantages [pic] †¢ The entire Application framework can be reused and replaced by selective components Wi-Fi network applications support (Depends on hardware) †¢ Dalvik[1] virtual machine enhances the power management systems †¢ Supports 2D and 3D graphics †¢ Supports common media file formats †¢ Reliable and enhanced data storage using SQLite framework[2] †¢ Open source Web-Kit Engine-based web-browser †¢ GPS, Navigational compass, Touch-Unlock, and acceleromet er applications support †¢ Androids development environment includes a device emulator, debugger, performance profiling tool, and an Eclipse IDE plug-in [pic] Logo of Android OS Architecture [pic] The main components of the Android architecture: 1. Applications: These are applications written in Java. Some of basic applications include a calendar, email client, SMS program, maps, making phone calls, accessing the Web browser, accessing your contacts list and others. [pic] 2. Application Framework: This is the skeleton or framework which all android developers has to follow. The developers can access all framework APIs an manage phone’s basic functions like resource allocation, switching between processes or programs, telephone applications, and keeping track of the phone’s physical location. The architecture is well designed to simplify the reuse of components. Think of the application framework as a set of basic tools with which a developer can build much more complex tools. [pic] 3. Libraries: This layer consists of Android libraries written in C, C++, and used by various systems. These libraries tell the device how to handle different kinds of data and are exposed to Android developers via Android Application framework. Some of these libraries include media , graphics, 3D, SQLite, web browser library etc. The Android runtime layer which includes set of core java libraries and DVM (Dalvik Virtual Machine) is also located in same layer. [pic] 4. Runtime Android: This layer includes set of base libraries that are required for java libraries. Every Android application gets its own instance of Dalvik virtual machine. Dalvik has been written so that a device can run multiple VMs efficiently and it executes files in executable (. Dex) optimized for minimum memory. [pic] 5. Kernel – Linux: This layer includes Android’s memory management programs, security settings, power management software and several drivers for hardware, file system access, networking and inter-process-communication. The kernel also acts as an abstraction layer between hardware and the rest of the software stack. pic] The basics of the Android kernel are just like any other monolithic architecture, all services (file system, VFS, device drivers, etc. ) as well as core functionality (scheduling, memory allocation, etc) are a tight knit group sharing the same space. The kernel of this system is both a hybrid and a monolithic modular design. It is br oken down into five major subsystems: †¢ Process Scheduler: (SCHED) responsible for controlling process access to the CPU. The scheduler enforces a policy that ensures that processes will have fair access to the CPU, while ensuring that necessary hardware actions are performed by the kernel on time. Memory Manager: (MM) permits multiple processes to securely share the machine's main memory system. In addition, the memory manager supports virtual memory that allows Linux to support processes that use more memory than is available in the system. Unused memory is swapped out to persistent storage using the file system then swapped back in when it is needed. †¢ Virtual File System: (VFS) abstracts the details of the variety of hardware devices by presenting a common file interface to all devices. In addition, the VFS supports several file system formats that are compatible with other operating systems. Network Interface: (NET) provides access to several networking standards an d a variety of network hardware. †¢ Inter-Process Communication: (IPC) subsystem supports several mechanisms for process-to-process communication on a single Linux system. System Threading By default, an Android application runs on a single thread[3]. Single-threaded applications run all commands serially, meaning the next command is not completed until the previous one is done. Another way of saying this is that each call is blocking. This single thread is also known as the UI thread because it’s the thread that processes all the user interface commands as well. The UI thread is responsible for drawing all the elements on the screen as well as processing all the user events, such as touches on the screen, clicks of the button, and so on. Threads may suspend themselves or be suspended either by the Garbage Collector (GC), debugger or the signal monitor thread. The VM controls all the threads through the use of a internal structure where all the created threads are mapped. The GC will only run when all the threads referring to a single process are suspended, in order to avoid inconsistent states. CPU Scheduling The Linux kernel uses the Completely Fair Scheduler (CFS), which has the objective of providing balance between tasks assigned to a processor and applies fairness in the way that CPU time is assigned to tasks. This balance guarantees that all the tasks will have the same CPU share and that, each time that unfairness is verified, the algorithm assures that task rebalancing is performed. Although fairness is guaranteed, this algorithm does not provide any temporal guarantees to tasks, and therefore, neither Android does it, as its scheduling operations are delegated to the Linux kernel. Android uses its own VM named Dalvik (see footnote 2), which was specifically developed for mobile devices and considers memory optimization, battery power saving and low frequency CPU. It relies on the Linux kernel for the core operating system features such as memory management and scheduling and, thus, also presents the drawback of not taking any temporal guarantees into consideration. [pic] In terms of execution, the algorithm works as follows: the tasks with lower virtual runtime are placed on the left side of the tree, and the tasks with the higher virtual runtime are placed on the right. This means that the tasks with the highest need for the processor will always be stored on the left side of the tree. Then, the scheduler picks the left-most node of the tree to be scheduled. Each task is responsible for accounting the CPU time taken during execution and adding this value to the previous virtual runtime value. Then, it is inserted back into the tree, if it has not finished yet. With this pattern of execution, it is guaranteed that the tasks contend the CPU time in a fair manner. Another aspect of the fairness of the algorithm is the adjustments that it performs when the tasks are waiting for an I/O device. In this case, the tasks are compensated with the amount of time taken to receive the information they needed to complete its objective. [pic] Since the introduction of the CFS, the concept of scheduling classes was also introduced. Basically, these classes provide the connection between the main generic scheduler functionalities and the specific scheduler classes that implement the scheduling algorithms. This concept allows several tasks to be scheduled differently by using different algorithms for this purpose. Regarding the main scheduler, it is periodic and preemptive. Its periodicity is activated by the frequency of the CPU clock. It allows preemption either when a high priority task needs CPU time or when an interrupt exists. As for task priorities, these can be dynamically modified with the nice command and currently the kernel supports 140 priorities, where the values ranging from 0 to 99 are reserved for real-time processes and the values ranging from 100 to 139 are reserved for normal processes. Process States The order in which processes are killed to reclaim resources is determined by the priority of the hosted applications. An application’s priority is equal to its highest-priority component. Where two applications have the same priority, the process that has been at a lower priority longest will be killed first. Process priority is also affected by interprocess dependencies; if an application has a dependency on a Service or Content Provider supplied by a second application, the secondary application will have at least as high a priority as the application it supports. All Android applications will remain running and in memory until the system needs its resources for other applications. A process has five different states. [pic] †¢ Active Processes Active (foreground) processes are those hosting applications with components currently interacting with the user. These are the processes Android is trying to keep responsive by reclaiming resources. There are generally very few of these processes, and they will be killed only as a last resort. Active processes include: o Activities in an â€Å"active† state; that is, they are in the foreground and responding to user events. You will explore Activity states in greater detail later in this chapter. Activities, Services, or Broadcast Receivers that are currently executing an onReceive event handler. o Services that are executing an onStart, onCreate, or onDestroy event handler. †¢ Visible Processes Visible, but inactive processes are those hosting â€Å"visible† Activities. As the name suggests, visible Activities are visible, but they aren’t in the foreground or responding to user events. Thi s happens when an Activity is only partially obscured (by a non-full-screen or transparent Activity). There are generally very few visible processes, and they’ll only be killed in extreme circumstances to allow active processes to continue. Started Service Processes Processes hosting Services that have been started. Services support ongoing processing that should continue without a visible interface. Because Services don’t interact directly with the user, they receive a slightly lower priority than visible Activities. They are still considered to be foreground processes and won’t be killed unless resources are needed for active or visible processes. †¢ Background Processes Processes hosting Activities that aren’t visible and that don’t have any Services that have been started are considered background processes. There will generally be a large number of background processes that Android will kill using a last-seen-first-killed pat- tern to obtain resources for foreground processes. †¢ Empty Processes To improve overall system performance, Android often retains applications in memory after they have reached the end of their lifetimes. Android maintains this cache to improve the start-up time of applications when they’re re-launched. These processes are routinely killed as required. State Diagram [pic] Memory Management Android’s process and memory management is a little unusual. Like Java and . NET, Android uses its own run time and virtual machine to manage application memory. Unlike either of these frameworks, the Android run time also manages the process lifetimes. Android ensures application responsiveness by stopping and killing processes as necessary to free resources for higher-priority applications. Each Android application runs in a separate process within its own Dalvik instance, relinquishing all responsibility for memory and process management to the Android run time, which stops and kills processes as necessary to manage resources. Dalvik and the Android run time sit on top of a Linux kernel that handles low-level hardware interaction including drivers and memory management, while a set of APIs provides access to all of the under- lying services, features, and hardware. Synchronization Techniques Regarding synchronization, Android uses its own implementation of libc – named bionic. Bionic has its own implementation of the pthread library and it does not support process-shared mutexes and condition variables. However, thread mutexing and thread condition variables are supported in a limited manner. Currently, inter-process communication is handled by Open-Binder. In terms of real-time limitations, the mechanisms provided by the architecture do not solve the old problems related with priority inversion. Therefore, synchronization protocols such as priority ceiling and inheritance are not implemented. Event Handling In terms of interrupt/event handling, these are performed by the kernel via device drivers. Afterwards, the kernel is notified and then is responsible for notifying the application waiting for that specific interrupt/event. None of the parts involved in the handling has a notion of the time restrictions available to perform its operations. This behavior becomes more serious when considering interrupts. In Linux the interrupts are the highest priority tasks, and therefore, this means that a high priority task can be interrupted by the arrival of an interrupt. This is considered a big drawback, as it is not possible to make the system totally predictable. Security Android has a unique security model, which focuses on putting the user in control of the device. Android devices however, don’t all come from one place, the open nature of the platform allows for proprietary extensions and changes. These extensions can help or could interfere with security, being able to analyze a distribution of Android is therefore an important step in protecting information on that system. Android applications run in a sandbox, an isolated area of the operating system that does not have access to the rest of the system's resources, unless access permissions are granted by the user when the application is installed. Before installing an application, Android Market displays all required permissions. A game may need to enable vibration, for example, but should not need to read messages or access the phonebook. After reviewing these permissions, the user can decide whether to install the application. Networking Android supports connectivity technologies including Global System for Mobile Communications (GSM)[4], Enhanced Data rates for GSM Evolution (EDGE)[5], Integrated Digital Enhanced Network (IDEN)[6], Code division multiple access (CDMA)[7], Evolution-Data Optimized (EV-DO)[8], Universal Mobile Telecommunications System (UMTS)[9], Bluetooth[10], Wi-Fi[11], LTE[12], (Near field communication) NFC[13] and Worldwide Interoperability for Microwave Access (WiMAX)[14]. Evaluation Mobile software development has evolved incredibly over time, giving us the power of not having to carry our laptop everywhere, or waiting to get home to access our networks or documents, 3G and 4G speeds directly on our phones give us that power, making mobile devices the most popular way to stay connected, as speeds are comparable to standard net speeds. Android has emerged as a new mobile development platform, building on past successes and avoiding past failures of other platforms. The android OS is an open source, meaning that is freely available to anyone who wishes to learn it. Google has opened up the software to creativity, because now we all have access to learning the development process. Hackers, coders, and all techy gurus have created a plethora of net-libraries ranging from support groups, forums and websites to further help newbies in the process. Android was designed to empower developers to think creatively by giving them almost absolute power over creating innovative applications. Bibliography Android Developers. Web. 11 Nov. 2011. .

Women and Minorities in Psychology

Before the call war women and minorities were not allowed to pursue higher education and were discouraged to study the sciences because of their lack of Intelligence. However, Margaret Washburn was the first woman to graduate with a doctorate In psychology studying with Ethylene In the area of visual Imagery on tactile sensitivity, (Goodwin, 2008). Dry. Washburn went on to become the president of the American Psychology Association in 1921 (Goodwin, 2008).African Americans were referred to as a â€Å"beast of burden† as was thought of as being even more inferior than the lowly female and it was the life that that if African Americans were educated it would encourage them to think about freedom ( Goodwin, 2008). During the post-civil war era African American's were allowed to attend a limited number of separate but equal schools, most attained teaching degrees and returned to their communities as teachers.Those African American's who did earn an advanced degree in psychology ac cording to Goodwin (2008), had a very limited opportunity to use their degrees other than teaching at a â€Å"black college†. Francis Sumner was the first African American to earn a doctorate degree in psychology in 1920 (Goodwin, 2008). Because of the school of thought at the time in the 19th century of the superiority of the white male's women and people of color were not granted the opportunity to pursue a higher education in the case of African American no education at all.They were treated marginally and living on the fringe of society as having no value as a human being at all. Women and people of color were disenfranchised and deem to have little or nothing to offer. Many African Americans credit W. E. Dubious as being the first African American psychology because he wrote so eloquent about the psychological struggles of African American in his classic work entitled The Souls of Black Folk's.The omission of women and people of color from the field of psychology, any ps ychology results would not have been an accurate because of the blabs of the studies; over half of the population was not included.
