A Brief History of the Doomsday Clock

In June 1947, almost two years after the destruction of Hiroshima and Nagasaki by atomic bombs, the first issue of the magazine Bulletin of the Atomic Scientists was printed, featuring a stylized clock on its cover. The clock displayed the time seven minutes to midnight, a symbolic representation of how close humanity was to destroying itself in a nuclear war, at least according to the judgment of the Bulletins editors. Since then, the Doomsday Clock has been an ever-present fixture on the world stage, set back when nations behave reasonably, set forward when international tensions wax, a constant reminder of how close we are to catastrophe. As you can probably infer from its title, the Bulletin of the Atomic Scientists was created by, well, atomic scientists: this magazine started as a mimeographed newsletter circulated among the scientists working on the Manhattan Project, an intensive, four-year effort that culminated in the bombs dropped on Hiroshima and Nagasaki. (The Bulletin is still published today, no longer in print form, since 2009, but on the web.) In the 70 years since its appearance, the mission of the Doomsday Clock has been slightly tweaked: it no longer refers specifically to the threat of nuclear war, but now signifies the likelihood of other doomsday scenarios as well, including climate change, global epidemics, and the unforeseen dangers posed by new technologies. The Ups and Downs of the Doomsday Clock One common misapprehension about the Doomsday Clock is that its updated in real time, like a stock-market ticker. In fact, the clock is only changed after meetings of the Bulletins advisory board, which happen twice a year (and even then, the decision is often  taken to keep the time as it is). In fact, the Doomsday Clock has only been set forward or back 22 times since 1947. Here are some of the most notable occasions when this has happened: 1949: Moved up to three minutes to midnight after the Soviet Union tests its first atomic bomb. 1953: Moved up to two minutes to midnight (the closest the Doomsday Clock has ever reached this mark) after the U.S. tests its first hydrogen bomb. 1963: Moved back to 12 minutes to midnight after the U.S. and the Soviet Union sign the Partial Test Ban Treaty. (One interesting side note: the Cuban Missile Crisis of 1962 started, and was resolved, in between meetings of the Bulletins advisory board. One imagines that if the clock had been reset during these seven tense days, it would have displayed a time of 30 or even 15 seconds to midnight.) 1984: Moved up to three minutes to midnight  as the Soviet Union is mired in war in Afghanistan and the U.S., under Ronald Reagan, deploys nuclear-tipped Pershing II missiles in western Europe. The international social fabric is further weakened by the U.S. boycott of the 1980 Olympic Games and the Soviet boycott of the 1984 Olympic Games. 1991: Moved back to 17 minutes to midnight (the farthest away the clocks minute hand has ever been) after the dissolution of the Soviet Union. 2007: Moved up to five minutes to midnight after North Korea tests its first atomic bomb; for the first time, the Bulletin also recognizes global warming (and the lack of firm action to counter it) as an imminent threat to civilization. 2017: Moved up to two  and one-half minutes to midnight (the closest the clock has been since 1953) following Donald Trumps tweets touting the U.S. nuclear arsenal  and the prospect of decreased legislative action to slow global warming. How Useful is the Doomsday Clock? As arresting an image as it is, its unclear just how much of an effect the Doomsday Clock has had on public opinion and international policy. Clearly, the clock had more of an impact in, say, 1953, when the prospect of a Soviet Union armed with hydrogen bombs conjured up images of World War III. Over the ensuing decades, though, one can argue that the Doomsday Clock has had more of a numbing than an inspiring effect: when the world is constantly a few minutes from global catastrophe, and the apocalypse never quite happens, most people will choose to ignore current events and focus on their daily lives. In the end, your faith in the Doomsday Clock will depend on your faith in the Bulletins high-powered advisory board and its network of professional experts. If you accept the evidence in favor of global warming and are alarmed by nuclear proliferation, youre likely to take the clock more seriously than those who dismiss these as relatively minor issues. But whatever your views, the Doomsday Clock at least serves as a reminder that  these problems need to be addressed, and hopefully soon.

Hiv In Children In The Uk Effects On The Child And Family Free Essays

string(68) " to safeguard their future potential and the sustenance of society\." Introduction The overarching theme of this essay is the effect of child health on the child and family. Concepts of health and illness are explored in pursuit of ways in which children’s health can be protected and maintained on different levels. The Human Immunodeficiency Virus (HIV) and its consequent disease state (AIDS) have in recent decades become a notable pandemic affecting the lives and livelihoods of ever increasing numbers of patients and the affected (UNICEF, 2011). We will write a custom essay sample on Hiv In Children In The Uk: Effects On The Child And Family or any similar topic only for you Order Now HIV is a terminal (lifelong) illness. However, advances in modern medicine, the improved availability and effectiveness of drug regimens means that the disease can now be managed better, enabling enhanced and prolonged lives for the infected (UNAIDS, 2008). It is therefore imperative that knowledge of HIV is improved, as this will help develop effective strategies for the promotion of affected children’s health, particularly in their formative years. In this regard, the understanding of factors influencing the health of children enables the raising awareness of the opportunities for effective health promotion. It aslo encourages focus on the effects of illness and poor health on the children and their families (Judd, et al., 2007). The effect of HIV in children in the UK and the overall health and well-being of children living with HIV including those exposed through maternal infection; children vulnerable to the impacts of HIV and AIDS such as those who have been orphaned, those living outside parental care, or in poor families; and children who are especially vulnerable to exposure to HIV because of their circumstances, such as those injecting drugs and those who are abused or sexually exploited, is the focus of this essay. This exploration of child health is conducted with particular focus on HIV in children in the UK. The incidence, prevalence, and changing patterns of disease are discussed backed by statistical evidence which enables the contextualization of the child health issue. The impacts of child health policies and provisions on the well-being of the child and family are also explored. Trends in child health issues Often, and to most people, health is considered to be the absence of disease or ill-health. However, advances in research into health have led to the identification of several influences making it essential to enhance this limited definition to encompass these. Health derives from the interaction of complex aspects and factors in a child’s environment such as genetic endowment and behavioural responses, each constantly affecting and influencing the other (Glanz, et al., 2008). In consideration of this, WHO defines health as, â€Å"†¦ a state of complete physical, mental and social well-being, not merely the absence of disease or infirmity† (WHO, 2005). Health can therefore be identified as a resource for daily life, a positive concept that emphasizes physical capabilities, as well as personal and social resources which infer the maintenance and optimization of function through time (Hall and Elliman, 2006). Child health, in this regard, is defined as the extent to which an individual child or groups of children are able or enabled to: develop and realize their full potential; satisfy their needs; and, develop capacity allowing their successful interaction with their physical, biological and social environment (Silberfeld, 2007; UNICEF, 2009). Comprehensive health promotion is based on the recognition that health and well-being are a result of the interaction of various multiple factors such as biological, psychological, social, cultural, and physical (Albon and Mukherji, 2008). In this regard, child health has to be looked at holistically to encompass not only the absence of illness but also other essential development aspects such as a healthy environment in which to grow and develop, play and learn. Based on this view and crucial to the assessment of child health, three domains are defined: health condition (the illnesses and disorders of body systems such as disease, injury, impairment, or signs and symptoms); functioning (the manifestations of health in daily life reflecting the direct and indirect effects of health); and, health potential (the development of health assets (capacities or reserves) that provide the capacity for response to physical, psychological, and social challenges as well as risk states which lead to vulnerability to poor health) (Green and Tones, 2010). Child health has at its core the growth and development of healthy children with capacity to reach their full potential as citizens of the world. Effects of poverty and inequality, for instance, may result in other compound factors such as poor nutrition, opportunity for educational development, and violence in the neighbourhood (physical safety), all of which lead to poor child health and/or health potential (Jones, et al., 2007; Wall, 2010). Poverty is often linked to poor health outcomes and significantly impacts children who suffer disproportionately, childhood being the most vulnerable periods in the life course (Wall, 2010). This is especially significant since a child’s quality of life is interwoven with the life and experience of the family in which they live or their carers. Without addressing problems affecting the child at home such as poverty, nutrition, housing, safety, as well as socio-cultural factors, the best quality of life for the child may not be attained (Department of Health, 2009; Shaw, et al., 2005). Such problems have been shown to have effects on health and well-being of individuals, and espec ially children in their critical and sensitive phases of development. Child health has gained significance from the realization of critical differences from adult health with consideration of broader aspects of health specific to children being elucidated (National Research Council (US)/ Institute of Medicine (US), 2004; British Medical Association, 1999). Differences with adult health include: dependence on adult carers or family for their raising, determination of diets, and access to services; different manifestations of poor health; developmental differences with more focus on children’s cognitive, emotional, social and physical growth critical in their growth and development; and their demography, with a large proportion of children in the UK living in poverty (Albon and Mukherji, 2008; UNICEF, 2009). Due to these critical issues, children’s health should be given due regard and attention to safeguard their future potential and the sustenance of society. You read "Hiv In Children In The Uk: Effects On The Child And Family" in categor y "Essay examples" Appropriate approaches should encompass comprehensive and coordinated care to address the needs of both adults and children in a family setting meeting overall health and social care needs (Adams, et al., 2002). Studies on child health in the UK conducted by the Department of Helath and private agencies have shown that practically all aspects of health fare worse among children from less affluent families and communities creating a link between poverty and poor child health (UNICEF, 2009; Hall and Elliman, 2006). Others studies conducted globally have aslo obtained similar findings, a direct relationship between illness and mortality (morbidity) with manifestations of deprivation whether social or economic such as poverty and unemployment. This shows that health differences are largely the product of the inequality in the distribution of wealth and income (). Currently, 3.5 million children live in poverty in the UK, almost a third of all the children. Close to half of this population live in conditions of severe poverty with families having as little as ?12 per day per person to cater for every need (food, toys, clothing, electricity and heating, and transport). Additionally, 18% dependent children in the UK live in households where no adults are in employment (UNICEF, 2009). This paints a grim picture for their overall health and well-being. This situation is made dire with regard to chronic illnesses such as HIV and AIDS affecting children directly or indirectly, often altering the capacity and ability of adult caregivers in their role, catering for the affected children. Often the condition also results in loss of parents or caregivers infected with the disease (Judd, et al., 2007). With poverty, the provision of good nutrition essential particularly for disease management in condition of HIV, quality housing in safe neighbourhoods and overall health promoting lifestyles is challenged. The HIV and AIDS condition is also prone to stigma and social segregation, which significantly enhances inequality over and above that due to poverty (Shaw, et al., 2005). These combined, and in addition to other environmental and social factors such as the relationships in the family and community, may profoundly impact the health of affected children. The nature and strength of such interactions may differ across an individual’s lifespan, and early influences may set in place a series of vulnerabilities and strengths that could significantly affect the fullness of life (Silberfeld, 2007). The HIV infection and its health consequences are discussed below exploring statistical evidence on incidence, prevalence and changing patterns of disease. Human Immunodeficiency Virus (HIV) Like all viruses, HIV cannot grow or reproduce independently and needs to infect cells of living organisms in order to replicate (to make new copies of themselves). However, unlike other viruses which are killed and cleared by the human immune system, HIV attacks essential components of the immune system itself, the T-helper cells of the immune system. The destruction of the cells of the immune system weakens the immune system until the body is no longer able to fight off other infections that it would usually be able to prevent, a condition referred to as AIDS (Acquired Immunodeficiency Syndrome). These subsequent infections are what lead to the death of the affected individual. They include conditions such as Tuberculosis, Kaposi’s sarcoma, among many others, often referred to as opportunistic infections (UNAIDS, 2008). HIV infection in children is often a result of mother-to-child transmission (MTCT) with a vast majority occurring due to maternofetal transmission of blood during birth or during postnatal breast-feeding. Other transmission routes such as through the sharing of needles in intravenous drug use or sexual activity/abuse are rare and only rise as children approach puberty (WHO, 2005). Overall, in the UK, over 2000 children aged 14 and under diagnosed with HIV as at end of June 2012 have been infected through MTCT. The population of children infected accounts for approximately 2% of overall HIV infections (Judd, et al., 2007). In 2011, there were 73,659 people in the UK diagnosed with HIV and receiving care. This number has increased every year in the previous decade, a 58% increase from 2002. 1 in every 500 men and 1 in 1000 women live with HIV and 1% of the total number of people receiving care are children under 15. Unfortunately, more people continue to be infected compounding the health problem (UNICEF, 2011). It is noteworthy that a study conducted between 2003 and 2006 did show that 64% of HIV-positive children resident in the UK had been born abroad with the unlinked anonymous surveillance program of 2006 that 1 in every 440 women giving birth in England and Scotland were HIV-positive with a 0.09% prevalence of previously undiagnosed infection. In the decade to 2006, the prevalence of HIV in women born in the UK increased by 66% (Judd et al., 2007). Children affected by HIV not only suffer from the direct effects of the disease state but also from the fact that their primary caregivers are often also affected, struggling with the effects of the disease, or have died from the disease (UNICEF, 2011). The management of the disease condition also entails long-term complex medication regimes which require readiness and motivation of affected individuals to pursue antiretroviral therapy to slow down its effects. Compliance with treatment regimens and good nutrition enables infected individuals to live long healthy lives enabling the recovery of their immune systems to robust state (Judd et al., 2007). A significant challenge to HIV’s life-long treatment regime is the problem of compliance, and with regard to children who often are difficult to administer medications to, the unavailability of paediatric formulations due to their relatively low prevalence, as well as the adverse side effects of medication present notable problems with the management of the condition (Judd et al., 2007). Children are also usually dependent on adult caregivers and with them probably also dealing with their own challenges, compliance and proper management of disease may not be achieved (Wall, 2010). It is therefore important to consider supporting the entire family rather than the individual child to achieve their overall well-being and health. This can best be achieved through effective health promotion strategies. Health promotion strategies associated with HIV in the UK Health promotion refers to the process in which people are enabled to increase control over their own health and its influences thereby achieving improvement in their health. This occurs primarily through the development of public policies of health addressing the prerequisites such as income, food security, housing, employment, and quality working conditions; as well as preventive and protective mechanisms (Department of Health, 2013). The UK’s government targets and objectives for the improvement of children’s and young people’s health nationally and locally is outlined in its overarching three year Public Service Agreements (PSA). They include the following: reduction in child poverty; improvement of the health and well-being of children and young people; improvement of child safety; enhancement of numbers of children and young people on the path to success; providing health and better care for all, including the tackling of health inequalities, as well as; enhancing participation in education and sport (Department of Health, 2009). These targets and objectives govern the development of laws, rules, and regulations developed at various levels of government (national, state or local). They determine the availability of public support services, as well as the regulation of the provision of services administered by private entities. These are integral to how communities in the entire region operate (Green and Tones, 2010). However, despite these endeavours and the Government’s statutory requirement to end child poverty by 2020 (as enshrined in the Child Poverty Act, 2010), it is predicated that by then, unfavourable policies and economic situation/constraints will push another 1 million children into poverty (Shaw, et al., 2005). Particular focus in HIV in children is the prevention especially of Mother-to-Child Transmission (MTCT) which is the main cause of their HIV infection. Several initiatives are undertaken, in this regard, such as the Unlinked Anonymous Surveillance program and the Voluntary confidential reporting mechanisms enhancing surveillance of this transmission route. These initiatives rely on voluntary confidential reports from paediatricians and obstetricians, as well as the use of prophylaxis (anti-retroviral therapy) to prevent transmission. These surveillance initiatives have had huge success leading to a sharp decrease of infections, with continued application of appropriate interventions having the promise of reduction of transmission rates to less than 1% (Judd et al., 2007). Children who have a confirmed HIV seroconversion should receive infectious disease management from specialist paediatricians. They should be involved in decisions about their care as much as possible, even when their capacity for independent decision is low (Judd et al., 2007). This is catered for in the long term plans of the Department of Health and the Department for Children, Schools and Families set out in the NHS Next Stage Review, The Children’s Plan and Healthy Lives, and Brighter Futures: The Strategy for Children and Young People’s Health. These reflect the Government’s ambition of enhancing child health with one of the main running themes being to refocus children’s health services as closer home as possible (Department of Health, 2009). This is achieved through managing children through ambulatory care and community based teams at home, school, and voluntary activity settings as, regarding HIV, longer term care provision continues intermittentl y throughout the lives of affected children. Health providers, agencies and voluntary teams have, as a result of changes in approach towards family and community-based care, developed working partnerships to work closely with families and children in treatment-oriented services, health promotion, and community-based care, contributing to better management, knowledge of condition and requirements, as well as strict adherence to regimen and overall well-being (Green and Tones, 2010; Adams, et al., 2002). Tactful communication of information on health to children is required as they try to find logic about illness and its causes developing from incomprehension to concrete and formal logical explanations as they mature(Wall, 2010). Health beliefs and behaviour The beliefs that people have about health problems, perception of potential benefits accrued from action, barriers to action, and individual ability and capacity can serve to explain engagement or lack in behaviour that promotes health (Glanz et al., 2008). Several perceptions, individual characteristics, and condition can serve to influence such behaviour and to drive or impede action. These include: Perceived seriousness or severity of health problem and its potential consequences (beliefs about the disease itself); Perceived susceptibility or assessment of potential risks of developing health problem (Judd et al., 2007); Perceived benefits of action or initiative; Perceived barriers such as inconvenience, expense, adverse effects of treatment, and discomfort preventing engagement; Individual characteristics including demographic (age, sex, race, ethnicity, education, etc.), psychosocial (personality, social class, and pressure from reference or peer groups, etc.), structural (previous contact with disease or knowledge about it) Triggers or cues to action which prompt engagement in health-promoting behaviour such as pain and symptoms (internal), and events or information from media, other people, health provides, or the illness of other individuals (external) – the intensity is attached to the perceived threat (Glanz et al., 2008) Self-efficacy/ability which refers to the confidence in one’s ability to alter outcomes which is often a key component in health behaviour change (Judd et al., 2007; Glanz et al., 2008). It is noteworthy that the behaviour of children with regard to health influences and is influenced by parents, peers and others (members of the community, health service providers, among others) (Glanz et al., 2008). However, the behaviour of children, just as parenting response and style may directly affect the ability to adhere to treatment regimen affecting compliance and thereby outcome of treatment. With a lack of understanding and underestimation of the threat of health problem leading to a lack of appreciation of its seriousness, their susceptibility, and the general causes and progress of disease, children affected by HIV may not be keen to adhere to their treatment regimen. This is especially so in HIV infection since, with proper management and care, symptoms exhibit intermittently. Adverse effects of medication which are common, the inconvenience of daily medication, and social issues such as segregation, therefore, act as barriers to their promotion of health-promoting behaviour (Judd et al., 2007). Family demography is also a significant influence on health behaviour with regard to its composition, financial status and parental education (British Medical Association, 1999). Low-income parents and especially those impacted by chronic illness are often considered to be at greater risk for depression and psychological distress, and consequently low self-worth and control impacting their ability to cope with adverse life experiences. They are therefore often engaged in compensatory poor health habits and detrimental behaviour such as smoking, substance abuse and violence negatively impacting health promotion for them and their dependents and worsening outcomes of illness (UNICEF, 2011). Poverty and its associated limiting factors also impacts compliance making factors such as costs of medication to be perceived as barriers with the little available resources used up on other essentials such as food and housing ignoring potential adverse consequences to health (Glanz et al., 2008). Conclusion As childhood disease burden shifts from acute infectious illnesses to chronic, long-term disease, the care of affected children becomes increasingly important. Early health particularly with regard to child health significantly influences future health and potential of not only the individual but the entire society. Greater focus need be trained on overall health and well-being of children, and particularly those infected and affected with HIV as it is often the case that their families are also adversely affected and likely unable, due to numerous challenges, to guarantee quality and comprehensive care.

Why the compromises from 1846~1861 failed to prevent the Civil War free essay sample

The compromises from 1846 to 1861 were, by their intentions, to postpone the struggle between the north and the south temporarily but not to solve it. The foundational problems, like the the slavery itself, the differences in social structure and economic system and the expansion of slavery, were left. The increasing struggle between the abolitionists and slave owners and between the newly formed Republican Party and the Democratic Party kept putting those questions in front of the US people. The compromises themselves failed to satisfy the wants of both sides, enraged the north and frightened the south, so up to the election of Lincoln, the tension built up to a climax and finally broke out to become a civil war. A major difference between the north and the south was the legality of slavery, according to compromise of 1820 the line of 3630 north divided this country into two parts, the southern parts contained with a large amount of plantations and slave owners. In the north the increasingly flourished international trades, the developing industrialization and the urbanization pushed the process to form the market economy, but in the west, because of the allowance of slaves, most economic activities were labor intensive as well as based on agriculture, which limited the development in industries and urban areas. Up to 1860 only New Orleans could be counted as a city with 168 thousands of people in the south. Although the south produced nearly 3/4 of the worlds cotton production, the industrial products were only 10% for the whole US. Slavery, as the foundation of southern economy, further influenced the opinions about race, the politics and the laws, while the north, mostly seen the south as behindhand and as a barrier of the advancement of US economy. One of the influences was about social structure, in the south the idea of patriarchy was dominant, and as the fact that the big slave owners gained social statue and political careers at the same moment, the south was like a nobility society and slavery is their footstone of the cotton kingdom. The differences, started initially with the slavery, were finally spread to all the areas that created a huge gap between the north and the south, they were very hard to understand each other because, for an example, the north saw the southern plantation owners as violators of freedom, but the south saw the northern workers as slaves of market. A compromise could never really worked when the two sides failed to understand each other. Politically, an important question was to maintain the balance in the senate, according to the Constitution, the number of senators was depended on the population of states, so the north were trying to have more free states, like the Wilmot Proviso did, but the south were dreaming to spread slavery to more states, like the decision of popular sovereignty. The south used to be dominant in USs political history but the active movements of northern parties like Free Soil, Know Nothing and the Whig, which eventually formed the Republican Party, supported the free labor which seemed had controversy with the idea of slavery. Although the Republicans could not necessarily be abolitionists, for a balance in power ( which could be seen as a kind of compromise) or for the idea of free labor, they would put effort to stop the expansion of slavery, and whatever their attitude was, the divide was existed and threatened the whole United States. The compromises could worked politically, but to control public opinion was also very important. After the Second Great Awakening the idea of Abolitionists had risen that the problem of slavery, that it must be solved or erased from the US. Theyve tried to ship some freed slaves back to Africa but later, by the efforts of black people, these movements tended to be acknowledging the citizenships of blacks and the equality within all Americans. Some secret societies had created to help the slaves escape from the south, like the Underground Railroad which help more than 6000 slaves to escape. The slave owners protected their property by the Fugitive Slave Laws, like the one in the Compromise of 1850, with the swear of any white people, a black could be counted as a fugitive slave and be sent back to the south. The books and newspapers further pushed these struggles, like the Uncle Toms Cabin. the Liberator and An Appeal to the Coloured Citizens of the World, rises the sympathy in the north to the slaves and increasingly frightened the south. The popular sovereignty used in New Mexico territories, the compromise of 1850 and the Kansas and Nebraska Acts were Victories of the south politically, however these acts were still seemed as compromises because both the north and the south were dissatisfied with these acts, that they could only be compromises but not victories. For the south the expansion of slavery was needed because the slavery was the foundation of southern society and economy, they had enjoyed less benefits from the fast developing northern industrial economy, if, without more lands and slaves moving to the new land, the expansion of production could not be achieved while their way of living could be challenged. For the northerners the process of industrial revolution went slowly in the south and with slavery the free labor could never come true. The Bleeding Kansas, Dred Scott Affair and John Brown created a sense that the movement of northern abolitionists had come to a climax, while the south itself, during the National Convention of Democratic Party, divided into two groups that one supported Douglas and popular sovereignty and the other supported John C. Breckenridge and the slavery. The conflict was now not just between the south and the north but also in both sides themselves. While the election of Lincoln created such atmosphere in the south that in the future 4 years the power of Republican Party and as well as the influence of the north would overwhelm the south by expanding their influences in the south, that, the Virginia and Kentucky Resolutions and Article of Confederation gave the south an excuse that they could leave the union without changing the southern way of living. The compromises from 1846 to 1861 failed to reduce the tension because the inner differences within the north and the south, the contradiction of expansion of slavery or market economy and the moral concerns that could not only solved by political methods, together with the division of the parties and their failed efforts towards compromises. The bloody incidents, prints and public debates heated the situation and acted like catalysts. Since the opposition was seemed impossible to solve, that both sides dissatisfaction increased over time and all the efforts towards compromises were finally given up.

Thesis Ethernet and Network Essay

Thesis Ethernet and Network Essay Thesis: Ethernet and Network Essay EVOLUTION OF CAT WIRING CAT-3 Wiring: The original CAT-3 wiring was popular in the early years of the ‘90s. This wiring was unshielded and was utilized in many computer networks, until it was replaced by the similar, but higher-quality CAT-5. CAT-3 had the capacity of carrying data at speeds up to 10MB/sec at a bandwidth of up to 16MHz. CAT-4 Wiring: This wiring never gained much popularity due to the fact that it was quickly unseated by CAT-5, shortly after it was introduced to the market. This wiring had the capacity to transfer data at 16MB/sec at a bandwidth of up to 20MHz. CAT-5 Wiring: This type of wiring was very popular throughout the ‘90s, once when it replaced CAT-3 and CAT-4. Its ability to carry audio and video data made it ideal for computer networks and use in Ethernet cable applications. CAT-5 wiring has the capacity to relay information at speeds of up to 1GB/sec, at bandwidth frequencies of up to 100MHz. CAT-5e Wiring: CAT-5e wiring is an enhanced version of CAT-5 wiring in that it has the same data rate (1GB/sec) and bandwidth frequencies (100MHz), except CAT-5e allows for data to be relayed at distances of up to 1,000 meters. Standard CAT-5 wiring only allows for signal relays up to 100 meters, without the use of devices such as connectors or repeaters, to allow for additional distance. CAT-6 Wiring: CAT-6 wiring was a revolutionary step towards complete cable functionality, with data rates of 10GB/sec at frequencies of up to 250MHz; however, the original CAT-6 is only capable of supporting these requirements over distances of 37 meters or less before it is exposed to alien cross talk. CAT-6a Wiring: CAT-6a is able to support 10GB/s data rates, at a distance of 100 meters. That’s nearly three times the distance of standard CAT-6 cable. Also, CAT-6a cable raised the bar for operating frequency range, allowing for function at bandwidths up to 500MHz. CAT-7 Wiring: CAT-7 cable has provided a more reliable solution to 10GB/sec data rates over 100 meter distances at frequencies up to 600MHz. CAT-7 wire is the closest replacement to fiber optic cable, as far as efficiency goes; however, singlemode fiber optic cable signals have the ability to relay signals across miles and miles, without the use of repeaters.

3 Ways to Avoid Confusing Your Readers

3 Ways to Avoid Confusing Your Readers 3 Ways to Avoid Confusing Your Readers 3 Ways to Avoid Confusing Your Readers By Mark Nichol Word choice, insertion or omission of punctuation, and syntax (arrangement of words and phrases) all affect comprehension. In each of the following sentences, one of these components of sentence construction is the source of ambiguity or confusion. Discussion of each example follows, along with a revision. 1. Our organization has sponsored AIDS/HIV walks across the country. Across is often used as a synonym for throughout, but here, it prompts the unfortunate misapprehension that the walks are transcontinental in scope. In this case, throughout is a better choice: â€Å"Our organization has sponsored AIDS/HIV walks throughout the country.† Take-away: Remain vigilant about ambiguous wording. 2. These results are not surprising because cyber risks have evolved into a moving target. This sentence, as written, suggests that the reader, after learning from the second half of the sentence what is not the reason the results are surprising, will read in a subsequent sentence the reason they are. But â€Å"cyber risks have evolved into a moving target† is the reason the results are not surprising, which is made clear simply by applying a brief pause to the sentence in the form of a comma preceding the explanation, which renders the explanation a subordinate clause set off from the premise of the sentence (â€Å"The results are not surprising†): â€Å"These results are not surprising, because cyber risks have evolved into a moving target.† Better yet, begin the sentence with the explanation, still in the form of a subordinate clause: â€Å"Because cyber risks have evolved into a moving target, these results are not surprising.† Take-away: When a negative statement is followed by an explanation, separate the explanation, a subordinate clause, from the main clause. (A positive statement generally needs no such punctuation, though exceptions exist.) 3. By taking a risk-based approach, such changes can be tailored to fit the company’s specific risk posture. All too often, writers mistakenly craft sentences in which subordinate clauses placed as introductory phrases are assumed to pertain to the subject of the main clauses when the two elements are only tangentially related. Here, changes are mistakenly said to take a risk-based approach, but an unnamed actor must be persuaded to do so. In most cases, simply revise the subject so that it logically follows the subordinate clause: â€Å"By taking a risk-based approach, one can tailor such changes to fit the company’s specific risk posture.† Take-away: Be alert to dangling participles.

Rent Policy in the UK Essay Example | Topics and Well Written Essays - 2000 words

Rent Policy in the UK - Essay Example Each individual Rent Policy today has its guidelines from the legal Restructuring framework. It will be the basis of this essay. The Tenant Service authority(TSA) was created in 2008 as an independent body to work with social housing providers to give structure, legal verification and guidance in the day to day running of their properties including almos. (Housing and Regeneration Act 2008). The TSA replaced the regulatory functions of the Housing Corporation. The Homes and Communities Agency (HCA) took over the investment functions and delivery activities of Communities and Local Governments. These two authorities cover all types of tenants in the United Kingdom. The Town and Country housing Rent Policy was chosen arbitrarily(T&CHG 2010) The TSA requires that 3 criteria be met . (TSA, 2010) "All Rent Policies must explicitly state their objectives in order to comply with the Housing Corporation's Rent Restructuring framework of 2002 . The Rent Policy shows that the rents are accessi ble to all. the rent increases are in alignment with current legislation. The association is a viable entity, earning enough revenues to maintain the property standards". Town and Country have several types of housing: social housing, shared ownership, market rent and intermediate rented stock. The Housing Corporation Rent Restructuring framework of 2002 and modified in 2009 is applied to social housing in its policy though other types of housing are also dealt with in this policy. "A person must have the choice of what type of place he can afford to have. Price should not be a determinant facture in deciding where he lives but it should determine what size of property he chooses" (Wilson, 2010) Government decision making at the local level has become less appreciated in the last few years. Associations have lost the power manage their own estates because the accountability and local decision making have become the responsibility of the government Target Rent Schemes have put people in a situation where it is no longer economically beneficial to go out and get a job. Needs have changed. Population sources are different. Social demands are no longer what they were 10 years ago Establishing the rent target calculations of 2002 did not take into consideration any of the social or financial factures of the last 10 years. Financial viability is difficult to achieve when household rents rather than property rents are used to subsidize the upkeep of estates. Rent are no longer linked to free market value. If it determined by the physical value, size and manual employment of the tenant (Wilson 2002, 3) and there is high unemployment in the area, the estates can no longer be viable. In 2009, bedroom weighting factor was added trying to add more value to property values. Manual labour was change to general employment. There were still too many variations. The 10 year plan has been met in the majority of areas other than London. The Governmental controls over Social Hous ing does not give enough control to the local councils as it was before 2002. This has been slowly changing since 2009. Public and government subsidised landlords must be able to have a combined free market of rent pricing. There is a chronic need of affordable housing. Millions of properties in the private sector are priced too high to rent and to buy. There are a million empty homes

State your side of the issues on, wheater stricter gun control laws Research Paper

State your side of the issues on, wheater stricter gun control laws reduce crime rates or does it increase the crime rates in texas - Research Paper Example The idea of gun control in the State of Texas is absurd for all reasons already mentioned in addition to the independent nature of the culture in Texas. Much the same as in other states, guns are a tradition passed from father to son, a way of life. Even if some types of guns were outlawed, the logistical problem and practicality of collecting them would also be absurd. According to the Second Amendment to the U.S. Constitution, â€Å"A well-regulated Militia, being necessary to the security of a Free State, the right of the people to keep and bear Arms, shall not be infringed† (â€Å"The Constitution†, 2006). This, as were the entire Bill of rights, was added by the founders of the country so as to provide a clearer definition of the specific rights granted to all Americans. Gun control supporters consider the Second Amendment to be â€Å"obsolete; or is intended solely to guard against suppression of state militias by the central government and therefore restricted in scope by that intent; or does not guarantee a right that is absolute, but one that can be limited by reasonable requirements† (Krouse, 2002). However, they only question the need for people to own firearms that are not primarily designed for sporting purposes such as hunting. Clearly, the right to own guns was of utmost importance to the Founding fathers given that it was listed second, after the freedom of speech and religion was acknowledged in the First Amendment. The Founders recognized that by ensuring the right to own arms, the public would have the ability to defend themselves from that which may jeopardize their life, liberty or pursuit of happiness. This could include physical protection from animals and persons and or from an tyrannical government that endangered the freedoms outlined in the Constitution. â€Å"The Second Amendment reflects the founders’ belief that an armed citizenry, called the ‘general militia’ was a necessary precaution against
