Sexually Transmitted Diseases :: essays research papers

Sexually Transmitted Diseases Sexually Transmitted Diseases STDs, a.k.a venereal diseases, infectious diseases passed from one person to another during sexual contact. STDs are the most common infections known. More than 12 million people in the United States, including 3 million teenagers, are infected with STDs every year. The United States has the highest STD rate in the world about one in ten Americans will contract an STD during his or her lifetime. People who do not know they are infected risk infecting their sexual partners and, in some cases, their unborn children. If left untreated, these diseases may cause pain or may destroy a woman's ability to have children. Some STDs can be cured with a single dose of antibiotics, but AIDS cannot be cured. Those most at risk for contracting STDs are people who have unprotected sex—without using a condom, people who have multiple partners, and people whose sex partners are drug users who share needles. Static’s show that A mericans between the ages of 16 and 24 are most likely of catching STDs than older adults, because younger people usually have multiple sexual partners than an older person in a long-term relationship. Teenagers may be embarrassed to tell their sexual partners they are infected Teenagers may also be embarrassed or unable to seek medical attention for STDs. This means that they only more likely to pass the disease to other young people and have a greater risk of suffering the long-term consequences of untreated STDs. STDs are transmitted by infectious bacteria, viruses, parasites, fungi, and single-celled organisms called protozoa that live in warm, moist parts of the body, like the genital area, mouth, and throat. Most STDs are spread while having sex, but oral sex can also spread disease. Some STDs are passed from a mother to her child while pregnant, when the disease enters the baby's bloodstream, during childbirth as the baby passes through the birth canal, or after birth, when t he baby drinks infected breast milk. AIDS can be transmitted by blood contact such as open wounds, between people who share infected needles or received through an injection of infected blood. Some people believe that STDs can be transmitted through shaking hands or other casual contact, or through contact with inanimate objects such as clothing or toilet seats, but they can’t. Chlamydeous, is from trachoma is bacterium, is the most commonly transmitted STD in the United States.

I felt a Funeral in my Brain Essay

Dickinson uses the metaphor of a funeral in her poem â€Å"I felt a Funeral in my Brain† to describe abstract emotions related to stressful situations that could destroy or take away everything that an individual values in life. The poem is quite permissive in the sense that it allows multiple readings where the reader may ascribe the emotions described in the poem to various situations that are difficult to cope with in life. Of course, to add dimension to the poem, Dickinson uses numerous poetic devices to enhance the experience of reading this particular piece. The piece features alliterations such as in the line, â€Å"I felt a Funeral, in my Brain,†. (1) Here there is a repetition of the consonant ‘f’ sound in the words ‘felt’ and ‘funeral’. Again, the same poetic device is seen in the line, â€Å"And I, and Silence, some strange Race†. (15) where the consonant ‘s’ sound is repeated in the words, ‘some’ and ‘strange’. Another one of these lines featuring an alliteration is the line, â€Å"And I dropped down, and down –â€Å". 18) While alliteration has no contextual function in these lines, the device serves to give the poem some sort of regular rhythm so that reading the poem is not just an intellectual experience, but also an experience that is enhanced by sound. The poem is given an interesting beat to it because of these alliterations. Another device intended to give the poem a more rhythmic quality is the assonance which is found in t he line, â€Å"Kept treading – treading – till it seemed†(3) where the vowel sound ‘ea’ is repeated in the word ‘treading’ and the vowel sound ‘I’ is repeated in the words ‘treading’,. ‘Til’, and ‘it’. In the same manner, the line, â€Å"And I, and Silence, some strange Race† (15) also demonstrates the use of assonance in the repetition of the vowel sound ‘I’ in the words ‘I’ and ‘silence’ and the repetition of the sound ‘ae’ in the words ‘strange’ and ‘race’. There are also metaphors in this very brief yet multi-dimensional poem. For instance, to demonstrate the frailty of reason, Dickinson writes, â€Å"And then a Plank in Reason, broke†. (17) Here one sees how reason is likened to a plank which breaks; a very clever way of illustrating the common human reactionary idiom which is ‘breaking under pressure’. Another metaphor in the poem is â€Å"With those same Boots of Lead, again† (11) which describes the heavy steps that a bothered or disturbed person makes. In effect, this particular line is an effective metaphor that illustrates the footfalls of a troubled or stressed person; perhaps, an experience that is familiar to most people as not having the energy to walk when stressed or trouble, hence heavy feet. Aside from metaphors, the very brief poem also manages to throw in a few similes, such as the line, â€Å"A Service, like a Drum –â€Å"(6), which likens the voices of the people in the funeral service to the incessant beating of a drum. So, the sound referred to in this line is an annoying or repetitive sound that seems to nag at the voice’s mind. Then, there is the line, â€Å"As all the Heavens were a Bell / And Being, but an Ear† (13-14) where the voice tries to illustrate how noisy or boisterous prayers are in the context of a person who is currently troubled or is dealing with problems that would seem insurmountable. These lines express the desperation of the state of the voice in that it describes how prayers are often empty and without significance or can do nothing to alleviate one’s sorry state. It is amazing how Dickinson is able to pack so many poetic devices into one very short poem. This demonstrates the brilliance of this poet in the art of poetry because it simply shows how expertly crafted and well-thought of the poem truly is. There is also a hyperbole in the poem in the lines, â€Å"And I dropped down, and down – / And hit a World, at every plunge† (18-19) describing the gravity or the seriousness of the state of the voice; hereto expressed as the feeling of falling down and hitting a world at every plunge. In effect, what the poet is saying here is that each disappointment or stressful situation puts the voice in a situation where he/she has to face the consequences presented or put before him/her by a confusing, unyielding, and indifferent society, here referred to as a â€Å"world†. Not to be left out in the poem is the personification which is found in the line, â€Å"And I, and Silence, some strange Race† (15) While personification is not immediately evident or apparent in this line, closer analysis of it would reveal, that in fact, personification is used to represent an abstract concept. When the voice puts silence in equal footage with himself/herself by treating silence as some sort of companion, personification is achieved. So, in this line, the voice of the poem claims that he/she and silence are both from a strange race; what this does is it gives the reader the illusion that apart from the ‘I’ who is a tangible concrete element of the poem, ‘silence’ which is an abstract concept also becomes a concrete element as it is personified by treating it as a companion of the ‘I’. This poem by Emily Dickinson simply demonstrates how craftsmanship is often very important in the creation of a poem. The intentions of a poet are mostly to convey emotion and to embody such emotion in words and the effective use of poetic devices achieves this particular poetic intention or objective. When a poem is able to effectively use poetic devices such reflects on the expertise and genius of the poet because while only some poetic devices can be found in some other singular poems, this poem packs in a large number, if not all poetic devices in the span of twenty lines spread throughout five stanzas. Such a feat is amazing in itself.

A Proposal of Metrics for Botnet Detection based on its Cooperative Behavior

The primary contribution of the paper is the proposal of three metrics that can help identify the presence of botnets in a wide area network (WAN). The proposed metrics, namely relationship, response and synchronization are measured with respect to the traffic over a WAN. It is assumed that the behavior of botnets will recurrently exhibit these metrics. The authors define relationship as the connection that exists between the bots and bot master of a botnet over one protocol. This metric tries to detect the structure of a botnet’s relationship by analyzing the network traffic.It is observed that the response time to commands received by a legitimate host varies significantly while that of botnets is comparatively constant. The response time as a metric can thus help detect botnets. As the bots present in a botnet are programmed to carry out instructions from the bot master on a predetermined basis, it is assumed that their activities will synchronize. An analysis of the networ k traffic can possible help identify synchronized activity between hosts, thus detecting botnets.The metrics are evaluated by analyzing traffic measured in the Asian Internet Interconnection Initiatives (AIII) infrastructure over a period of 24 hours. The analysis validates the metrics proposed as a dense topology relationship, short range of response times and synchronization of activities are detected in the presence of a botnet. The authors propose that a combination of all the metrics be used for detecting a botnet. The design of an algorithm to detect botnets based on a combination of the three metrics has been identified as future work. Summary of â€Å"IRC Traffic Analysis for Botnet Detection†The paper addresses the problem of detecting botnets by modeling the behavior of botnets. The main idea of the paper is to analyze network traffic, model the behavior of botnets based on the analysis and use pattern recognition techniques to identify a particular behavior model a s belonging to a botnet. The proposed model for detecting botnets analyses traffic that uses the IRC protocol. A traffic sniffer is used to analyze packets in the promiscuous mode. The protocol detector detects traffic using the protocol of interest to the analysis, in this case IRC.The packets are decoded using the IRC decoder and the behavior models are built. The detection engine detects a botnet based on the behavior model. The features used to build a behavior model include features related to a linguistic analysis of the data that passes through an IRC channel in addition to the rate of activity in the channel. It is observed that the language used by bots has a limited vocabulary and uses many punctuation marks. The language used by humans is observed to have a wider mean and variance with respect to the words used in a sentence. The features used to model the behavior of botnets hare listed.The experiments have been conducted with clean data collected from chat rooms and bot net data collected at the Georgia Institute of Technology. Pattern recognition is performed using support vector machines (SVMs) and J48 decision trees and the results are reported in terms of confusion matrices. Though the botnets are detected using the above methods, the authors report that a further analysis of the data is necessary. Unsupervised testing of the model and expansion of the model for adaptation to other scenarios is proposed as future work. Summary of â€Å"The Automatic Discovery, Identification and Measurement of Botnets†The paper proposes a technique for identifying and measuring the botnets used to deliver malicious email such as spam. The implementation and performance of the proposed technique has been presented. The authors are of the opinion that the existing methods for detecting botnets used to send spam use significant amount of resources and are often applicable only after a botnet has been operational over a period of time. The authors propose a passive method for identifying botnets by classifying the email content. The headers present in the emails are used to group the mails.The authors assume that a botnet has a central center for control and that the same program is used by a botnet for creating and sending spam emails. Based on these the authors propose to classify emails by a passive analysis of the header content present in them. The Plato algorithm is proposed to identify the sender and the program used to send the email. The performance of the Plato algorithm is analyzed based on the following factors: clustering, durability, isolation and conflicts. The analysis is performed on a sample data containing 2. 3 million emails. In the dataset 96% emails are identified as having a probability of being spam.The algorithm is observed to successfully reflect the features associated with spam email. It helps group the emails based on the characteristics of the sender and the sending program. This grouping of emails can hel p identify a botnet and thus enable the membership and size of the botnet. The authors propose that the algorithm can be further used for classifying bulk emails, to understand the relationship between spam and viruses and as a replacement for spam filters using statistical methods. Summary of â€Å"Towards Practical Framework for Collecting and Analyzing Network-Centric Attacks†The paper proposes a network-centric framework based on an awareness of risk to help detect attacks from a botnet and prevent these attacks. The authors state that the bots follow certain network traffic patterns and these patterns can be used to identify a bot. The proposed framework consists of three main components, namely bot detection, bot characteristics and bot risks. The first component, bot detection, is used to detect known and unknown bots that try to penetrate the system. A honeypot based malware collection system component is used to attract bots to the honeypot and thus help detect bots. After the bots have been detected the characteristics of the bots are analyzed. The behavior of bots and their characteristics are identified by analyzing known malware, network traffic patterns and detecting the existence of any correlation between various instances of a malware. Various components are used to perform each of the tasks involved in bot characterization. To determine the risks posed by bots, the vulnerabilities present in the existing system are identified. The risk posed by a host with certain characteristics is calculated based on the vulnerabilities associated with the system. Thus the risk factor can be modified on demand.A combination of the identified characteristics and the associated risks is evaluated when a decision regarding the blocking of traffic is made. The authors present results that demonstrate the ability of the proposed framework to detect different types of bots. The feasibility of the proposed framework has been demonstrated. Enhancing of the co rrelation system and integration of the risk aware system with the architecture are proposed as future work. Summary of â€Å"Wide-Scale Botnet Detection and Characterization† The paper proposes a methodology based on passive analysis of the traffic flow data to detect and characterize botnets.A scalable algorithm that gives information about controllers of botnets is proposed based on analysis of data from the transport layer. Four steps have been identified in the process of detecting botnet controllers. Suspicious behavior of hosts is identified and the conversations pertaining to this host are isolated for further evaluation. These are identified as suspected bots. Based on the records of suspected bots, the records that possible represent connections with a controller are isolated. This is referred to as candidate controller conversations in the paper.These candidate controller conversations are further analyzed to identify suspected controllers of botnets. The analysis is based on calculating the following: the number of unique suspected bots, distance between model traffic and the remote server ports, heuristics that gives a score for candidates that are possible bot controllers. The suspected controllers are validated in three possible ways: correlation with other available data sources, coordination with a customer for validation and validation of domain names associated with services (Karasaridis, Rexroad, & Hoeflin, 2007).The botnets are classified based on their characteristics using a similarity function. An algorithm is proposed for the same. The authors report the discovery of a large number of botnet controllers on using the proposed system. A false positive of less than 2% is reported based on correlation of the detected controllers with other sources. Also the proposed algorithm is reported to successfully identify and malicious bots. The future work is identified as the need to expand the algorithm for other protocols and analysis of the evolution of botnets.References Akiyama, M. , Kawamoto, T. , Shimamura, M. , Yokoyama, T. , Kadobayashi Y. , & Yamaguchi, S.

Assignment 6 Example

Assignment 6 Example Assignment 6 – Essay Example Identification Number Number Assignment number Assignment There are several theories pertaining the origin of life. Some of them include; extraterrestrial, heterotrophy, autotroph and they will form the basis of this paperExtraterrestrialThis is a hypothesis that tries to explain the origin of life on earth. Thus Panspermia is a hypothesis that claims life arose outside of the earth, meaning living things were transported to earth. There is a lot of evidence pertaining to this such as the evidence exhibited from the meteorite. The meteorites originating from Mars were discovered to contain complex organic molecules. There is also evidence from the exploration expedition in Mars which discovered that there was existence of water bodies earlier on in Mars. These bodies of water were thought to have previously supported life (Enger, Ross, Bailey, 2010).HeterotrophyThe other theories involve the development of metabolic pathways. This hypothesizes that the very first cells would have to have a way of adding new organic molecules, a process which requires energy. To obtain this energy, two ways are involved; heterotrophs capture organic molecules from their environment whereas autotrophs utilize external energy sources to make organic molecules. The heterotrophy hypothesis proposed that the first cells lived off organic molecules present in the ocean. These organisms would have been anaerobic since the atmosphere was reducing. As the organisms continued reproducing and organic molecules became depleted, mutation could have reproduced an organism that was capable of metabolizing other material into organic material a process that would be adaptive and would promote survival (Enger, Ross, Bailey, 2010).AutotrophAutotroph hypothesis on the other hand proposes that the first organisms were autotrophs and several Achaea (primitive organisms) that lives in extremely harsh environments are usually autotrophs. They usually utilise the energy that is released from inorganic chemical reactions to make organic molecules. Most probably, early competition amongst autotrophs would have led to the evolution of heterotrophic organisms and autotrophic organisms that could utilise other kinds of molecules and energy sources (Enger, Ross, Bailey, 2010).

Structure of the Healthcare Industry Essay Example

Structure of the Healthcare Industry Essay Example Structure of the Healthcare Industry Paper Structure of the Healthcare Industry Paper Health care is one of the fastest growing section of the economy, and differs from other services in various ways (Danzon, 1992). The output of a bakery is bread but the output of the health care industry is less detailed or defined. The health care industry is changeable and unpredictable, making it less understood by both producers/suppliers and consumers (Danzon, 1992). However, the health care industry still operates within the basic rules of economics, and economical analysis is required in assessing public policy (Danzon, 1992).   The end product of medical care is, of course, health. Probabilities on health can only be applied and quantified before care is actually provided (Danzon, 1992). The risk and threat of illness usually leads people to require health insurance. In the U.S., the market for health insurance is influenced by the fact that employer contributions are an integral part of employee compensation which is tax-exempt (Danzon, 1992). Thus, third party payment affects the basic structure of the health care industry (Danzon, 1992). Because insurance companies pay for a large percentage of medical care, a consumer’s â€Å"point-of-purchase† price has to be less. If a physician charges $20 and the insurance company pays for 80% for the charge, then the consumer’s price is on $4 . Like any other market, the quantity demanded goes up when price goes down. It is hard to measure quality of service based on the effect of insurance (Danzon). The presence of a particular government is heavily felt in the health care industry. In the U.S., the largest health insurer is Medicare or Medicaid (Danzon, 1992). Increase in Health Care Costs Health care costs have rapidly increased in recent years, mainly because of fast trends in medical technology (Danzon, 1992). Nevertheless, an effective resource allocation ensures that the medical benefits exceed marginal costs (Danzon, 1992). Hospitals play a major role in the health care industry (Danzon, 1992). Medicare implemented a â€Å"prospective payment system† in 1983, under which hospitals are paid a fixed charge per admission, basing on the diagnosis of a patient. This way, the hospital shoulders the partial cost of all expenses incurred by the patient. Physicians also play a major role in the health care industry (Danzon, 1992). The actual number of doctors who are active in providing care for patients have more than doubled (Danzon, 1992). This increase may be attributed to medical schools’ responses to federal subsidies created to multiply the supply of doctors after the entrance of Medicare and Medicaid (Danzon, 1992). In most markets, increases in supply would result in lower prices, and thus, a higher quantity. However, many doctors have relocated to rural areas that were otherwise unserved. There is a persistent connection between number of doctors per capita, and the prevalence of home-visits and surgical procedures. Another influence in the Health care industry is pharmaceutical trends. U.S. prescription of drugs grew by 16.9% in 2001 compare to 2000, making the pharma industry a $172 billion industry (Boyle, 2002).

Presidential Retirement Benefits

Presidential Retirement Benefits Presidential retirement benefits were non-existent until the enactment of the Former Presidents Act (FPA) in 1958. Since then, presidential retirement benefits have included a lifetime annual pension, staff and office allowances, travel expenses, Secret Service protection, and more. The FPA was inspired by former President Harry Trumans life of modest means after leaving office. Though Truman lived well more than a decade after the acts passage, it didnt apply him. Former President Dwight D. Eisenhower became its first beneficiary. Pension Former presidents are offered a taxable lifetime pension equal to the annual rate of basic pay for the heads of executive branch departments, like the Cabinet Secretaries. This amount is set annually by Congress and is currently  $210,700  per year. The pension starts the minute the president officially leaves office at noon on Inauguration Day. Widows of former presidents are provided with a $20,000 annual lifetime pension and mailing privileges  unless they choose to waive their right to the pension. In 1974, the Justice Department ruled that presidents who resign from office before their official terms of office expire are entitled to the same lifetime pension and benefits extended to other former presidents. However, presidents who are removed from office due to impeachment forfeit all benefits. Transition Expenses For the first seven months, beginning one month before the January 20 inauguration, former presidents get transition funding to help them transition back into private life. Granted under the Presidential Transition Act, the funds can be used for office space, staff compensation, communications services, and printing and postage associated with the transition. The amount provided is determined by Congress. Staff and Office Allowances Six months after a president leaves office, they get funds for an office staff. During the first 30 months after leaving office, the former president gets a maximum of $150,000 per year for this purpose. Thereafter, the Former Presidents Act stipulates that the aggregate rates of staff compensation for a former president cannot exceed $96,000 annually. Any additional staff costs must be paid for personally by the former president. Former presidents are compensated for office space and office supplies at any location in the United States. Funds for former presidents office space and equipment are authorized annually by Congress as part of the budget for the General Services Administration (GSA). Travel Expenses Under a law enacted in 1968, the GSA makes funds available to former presidents and no more than two of their staff members for travel and related expenses. To be compensated, the travel must be related to the former presidents status as an official representative of the United States government. Travel for pleasure is not compensated. The GSA determines all appropriate costs for travel. Secret Service Protection With the enactment of the Former Presidents Protection Act of 2012 (H.R. 6620), on Jan. 10, 2013, former presidents and their spouses receive Secret Service protection for their lifetimes. Under the Act, protection for the spouses of former presidents terminates in the event of remarriage. Children of former presidents receive protection until they reach age 16. The Former Presidents Protection Act of 2012 reversed a law enacted in 1994 that terminated Secret Service protection for former presidents 10 years after they left office. Richard Nixon is the only former president to have given up his Secret Service protection. He did so in 1985 and paid for his own security, saying his reason was to save the government money. (The savings were estimated to be about $3 million a year.) Medical Expenses Former presidents and their spouses, widows, and minor children are entitled to treatment in military hospitals. Former presidents and their dependents also have the option of enrolling in private health insurance plans at their own expense. State Funerals Former presidents are traditionally granted state funerals with military honors. Details of the funeral are based on the wishes of the former presidents family. Failed Attempt to Cut Retirement In April 2015, Congress passed a bill titled The Presidential Allowance Modernization Act, which would have capped the pensions of all former and future former presidents at $200,000 and removed the current provision in the Former Presidents Act linking presidential pensions to the annual salaries of cabinet secretaries. The bill would have also reduced the other allowances paid to former presidents. Annual pensions and allowances would have been limited to a total of no more than $400,000. But on July 22, 2016, President Barack Obama vetoed the bill stating it â€Å"would impose onerous and unreasonable burdens on the offices of former presidents.† In a press release, the White House added that Obama also objected to provisions of the bill that would â€Å"immediately terminate salaries and all benefits to staffers carrying out the official duties of former presidents- leaving no time or mechanism for them to transition to another payroll.†Ã¢â‚¬â€¹

Photo analysis research paper Example | Topics and Well Written Essays - 1250 words

Photo analysis - Research Paper Example Every aspect of study or academic always improves in quality with time. Most ideas in various fields of education are comparable and some are derivative of the other. However, art as a field or subject of study in colleges and universities does not obey the law as explained in the Arnold Hauser’s Sociological Method in Art History. Analyzed well, early photography had certain styles and compositions that depicted a higher level of professionalism. Most renaissance photos are discrete and can be differentiated from modern photos using different criteria. To begin with, renaissance photos like the one to below had certain artistic inputs that make them stand out when compared to the modern photos. Coloration in photography during the renaissance period was meant to portray certain themes to the viewers. Black color, for instance, symbolized a gloomy or despondent mood in a society. Red was always associated with romance. White, on the other hand, had a close association with rel igion especially Christianity. It was also associated with peace and understanding among people in the society. Drawings in the renaissance photos had a lot concerning the history of different societies. Drawings with weapons such as swords symbolized war, victory or a safe society. Political-based, early artists had various ways of displaying their political interests or ideologies using photos. For instance, an artist may decide to draw cartoons representing two different politicians, one cartoon may be bigger than the other. In such cases, the artist is secretly and artistically displaying his or her ideologies in politics. The big photo is always the artist’s most preferred politician. The paper will analyze the following photo with regard to the stated problem. According to this photo, a woman wearing a red dress is sitting on a dinner table next to circular window. She is not eating; there is food on the table, however. The woman has a long hair and looks somehow stress ed. Outside the window, there is a lot of light and this is contrast to the dark room where the woman is sitting (Matheson 287). The image is covered a slant rectangular frame. In addition, the window shows another shape of heart. The woman looks uneasy and impatient with her hands over her head. John William Waterhouse did this photo in 1849. According to him, the photo on the background is a lady of Shalott saying that she is half-sick of shadows. Various questionnaires were distributed to identify people’s views on the photo. One of the questions in the questionnaire were:What do you think of when you come across a woman with a red dress like the one in the photo? Does the picture reveal anything related to romance to you?If yes, where and when do you think this photo was taken? Out of the 100 questionnaires distributed, 71% associated the photo with romance and renaissance period. Most of them associated it with Europe, particularly Italy, France, and Germany. 22% associa ted the woman with early prostitutes in Europe. 7% of the questionnaires were not properly filled. According to the findings, it is quite succinct that William’s main thematic concern at the time of taking this photo was romance. First, the photo has its window in the shape of a heart. Heart, as understood, is a global symbol of romantic love. The window curtains have been removed allowing some light into the dark room. The woman is also in a red dress. Red color has
