Factors Contributing to Premarital Sexual Behaviours Essay Example
Factors Contributing to Premarital Sexual Behaviours Essay Example Factors Contributing to Premarital Sexual Behaviours Essay Factors Contributing to Premarital Sexual Behaviours Essay I am grateful for helping me make the study comprehensive by giving in-depth personal information. My English Tutor I would like to thank her for the helpful advices and her help on distributing the questionnaires. My Mother I would like to thank her for helping me with the printing and layout of the study.Ã Ã Transcript It came to my awareness that there is an increasing trend of sexual intercourse experience among teenagers in recent years. And the problem of teenage pregnancy has become a growing cause of concern of Hong Kong people. According to a survey done by the Hong Kong Council of Social Service in 2007, over half of the respondents have sex for the first time at the age of 14, and 83% of the respondents accept sexual intercourse. These data reflects that teenagers sex concepts are getting open and premarital sex is gaining popular acceptance. Under information explosion, I dread more and more teenagers will be exposed to pornographic or other harmful materials, driving them to have premarital sex, ultimately results in teenage pregnancy and bring intergenerational suffering. Worse still, sex today is still a taboo issue. People tend to avoid talking about it because it seems negative and they think it is embarrassing to share the experience, fearing that others may look down upon them. I therefore want to find out why teenagers accept or engage in premarital sexual behaviors by giving out questionnaires where respondents are anonymous and their privacy thoughts can be protected. Then by the end of the project, based on the reasons why some teenagers accept or engage in premarital sex and why some do not, I could give suggestions to different on ways to promote sexual abstinence. : The objectives of the study are as follows: ?To find out why teenagers accept or engage in premarital sexual behaviors ?To understand why some teenagers refrain from premarital sexual behaviors ?To make use of reasons for teenagers to refrain from premarital sexual behaviors to suggest ways to promote sexual abstinence ?To see what ways can be adopted by different stakeholders to promote sexual abstinence ?To see in what ways the sex education curriculum can be improved To raise teenagers awareness on the issue 3. 1. Questionnaire The target respondents are teenagers aged 12-19. 00 responses were collected by simple random sampling. The questionnaire consists of four parts. The first part seeks to understand respondents background and to know whether or not they accept or engage in premarital sexual behaviors. The second part asks the respondents why do not they accept and engage in premarital sexual behaviors. The third part asks others why they accept or engage in the behaviors. The final part asks how sexual abstinence can be effectively promoted to them. Limitations and Respective Solutions I put my questionnaire online to enable easy access. Yet some reflected to me that they could not understand the English. I then translated my questionnaire into Chinese so more could understand what I am trying to ask. I created an event on Backbone to invite my friends fill out my questionnaire. I get many responses, yet most respondents are within my social circle. This makes the study not credible as it cannot reflect what different teenagers in society think. To make my study more representative, I left 40 copies at my English tutors home, and each of her student did it. Lastly, the length of the questionnaire may make respondents feel tedious. Also, the data collected may not be detailed or in-depth enough. Thus, the questionnaire encompasses mainly multiple choice questions. And interviews were carried out to obtain detailed responses. Also, sex is a taboo issue. Some may not be willing to disclose what they think. So, the data collected is anonymous. 3. 2. Interviews The data collection process includes three interviews. Detailed and in-depth first- hand information was obtained. Interviewee 1 is a 15-year-old Christian girl who refrains from premarital sexual behaviors. She was interviewed so that I could understand how religious values can be used to promote sexual abstinence. Interviewee 2 is a 17-year-old boy who is from a broken family, dropped out since he as 13, and engages in premarital sexual behaviors since he was 14. I would like to use his perspective to understand why some marginal youth engage in premarital sexual behavior, and how we could promote sexual abstinence to them. Interviewee 3 is a teacher who has an 18-year-old son. I want to see if adults have some misconceptions on why teenagers engage in sexual behavior and on their roles in promoting sexual abstinence. These three persons have different education, economic and religious background. So, I can comprehensively understand what are the factors for teenagers engagement in premarital sexual behaviors. Limitations and Respective Solutions Teenagers may not have enough understanding about why they engage or accept premarital sex. They may overlook some reasons for their rejection or acceptance of premarital sexual behaviors. Therefore, the data collected maybe biased and subjective. Also, the questions I asked may not be comprehensive enough to look into the issue objectively and all-roundly. Lastly, the three interviewees could not represent all teenagers. To make the interviews more representative of teenagers in Hong Kong, three interviewees from different backgrounds were chosen. And the subjective information could be complemented by past studies and questionnaires. Premarital sex refers to intercourse before marriage. The Youth Sexuality Study reveals an increasing trend of sexual intercourse among Form 3 to Form 7 students. And according to a surveys whose targets population is youth-at-risk under the age of 18, over half of the respondents had their first intercourse when they were 14. These data shows a growing prevalence of premarital sex, and has alarmed the public about this pressing issue. Considerable factors were found to have contributed to the issue. First, insufficient parental sex education perceivably cause premarital sex. Amber Madison wrote in her book that many parents think teens friends influence their decisions to have sex the most, so they did n ot talk about sex with their kids. A study points out that nearly 98% of the interviewed parents indicated that they should be the primary source of sex-related information for their kids, yet only 24% of thought this was actually happening. From these, researchers concluded that parents often underestimate the importance of their role in educating adolescents about sex. Then, family background have far-reaching influence ones attitude towards sex. Ms. Lee Way Ski, the chief social worker of Youth Outreach pointed out that part of the girls who were casual in sex was from problem families. And Alai March-Eyres, the Chief Executive of Mothers Choice, pointed out many of the girls who Mothers Choice has been serving in the past 25 years are from poor, and often broken families. They thirsted for love, which they could not feel from their families. They then obtained care through hugs or kisses. Gradually they were willing to have sex with boys. Alai March-Eyres from Mothers Choice suggested that parents of some teens do not have time to provide them with the support they need. Some even have to shift from home to home between relatives and family friends. They then feel that they do not have much love in their lives, and end up in looking for love and support elsewhere. Edison Chain, who had a pornographic scandal in 2008 illustrates the idea. His parents The Youth Sexuality Study, Family Planning Association, 2006 2 The Hong Kong Council of Social Service, 2008 3 Amber Madison, Talking Sex with Your Kids, 2010 4 Journal of Adolescent Health, January 2011 Post-ass Accept Sex before Friendship in order to get along with friends, Hong Kong Economic Times, 9th July, 2012 6 A much-needed lifeline for pregnant teens, South China Morning Post, 3rd December, 2012 7 Sex Photo Scandal? Complicated Family Background, Edison Chain Got Perverted concealed their broken marriage until it was unveiled when he was 14. Being deceived, and to seek love, Edison had sex for the first time. The collapse of family values can drive one to have premarital sex. Peer pressure can drive one to have premarital sex. A seniors at a high school in America addressed that peer pressure sakes it almost impossible to stop having sex. Adolescents dread being thought to be outdated. They follow their friends to have sex so as to gain recognition and fit into the crowd. The lack of interpersonal skills can lead adolescents to have premarital sex. It is revealed that some girls longed to get into boys social circles. Sacrificing their purity, they had sexual intercourse with those boys. Tam Chunk Hoi, Chief President of Youth Outreach pointed out that those teen girls did not have many friends. Having sex was the quickest and easiest way to get close to boys, yet he girls did not know the boys were taking advantage of them. Pop culture is potent to affect ones decision about sex. A researches reveals that teens that had high exposure* to sexually degrading lyrics were more likely to have sexual intercourse. The song California Girlsl Using by Kathy Perry consists of lyrics like sex on the beach, and this behavior is considered what a hot girl should be doing in the song. The meaning of another song, Inferior Animal12 (#5) sung by Season Chain depicts a guy falls in love with a girl Just because of his desire for her body. These lyrics infuse adolescents with wrong values. Yet, broadcast containing sexual content can arouse teens awareness of their sexual behavior. A researches shows that over 67% of males and 79% of females agree that watching a TV show or a character they like dealing with teenage pregnancy makes them think more about their own risk about causing a pregnancy or getting pregnant. The overall effect of the media on teenagers attitudes about sex has long been an issue of concern for parents and health care professionals as the media have both positive and negative impacts on adolescents. 8 Alexis Ware, A Teenagers Thoughts: Pregnancy, Abortion, Sex and Peer Pressure, All Before Age! , Empowered Peace, September 27, 2010 9 Post-ass Accept Sex before Friendship in order to get along with friends, Hong Kong Economic Times, 9th July, 2012 10 Brian A, Primacy et al, Exposure to Sexual Lyrics and Sexual Experience among Urban Adolescents, American Journal of Preventive Medicine, April 2009 exposure was calculated by multiplying each respondents hours of music exposure by the percentage of his/her favorite artists songs that contained sexually degrading lyrics) Lyricisms.

Miriam Grossman wrote in his book14 that young minds,book are responsible for reasoning, suppression of impulses, and weighing the pros and cons of ones decision, are not fully developed. And under stimulating or intense conditions, teens decisions are more likely to be shortsighted and driven by emotion. So apart from the circumstances they face, their underdeveloped minds also contribute to their premarital sexual activities. Quests for love and self-esteem are also forces driving teenagers to have sex. 1 5 According to the experience of Alia Marwah-Eyres, the CAlai MarchiEyres Mothers Choice, most girls on crisis pregnancy are not naughty, but are Just desperate for love. These girls do not have someone to tell them that their lives have values, and that they worth it. This results in low self-esteem, driving them to have sex. Upon completion of the literature review, it is felt that there are some knowledge aps because most sourcesAPSom the US. It is uncertain if what influences Hong Kong teens are the same. Other factors like government policy, movies and clubbing culture may also motivate our adolescents to have sex. Due to the existing unknowns about factors contributing to premarital sex, it is decided to compare the above factors with what Hong Kong teenagers think. Also, we all know that all sexual contacts carry risks.Ã'â Pregnancy and the infection of STDs harm both physical Studsmental health of teenagers. Unfortunately there is hardly a comprehensive programme for all stakehprogrammer promoting sexual abstinence. So, there is a need for finding ways to promote sexual abstinence.

Helium Essay Example | Topics and Well Written Essays - 1750 words
Helium - Essay Example Nobel Prize winners in Physics like R. Richardson with colleagues Osheroff and Lee, nevertheless, points out the essential features of ââ¬Ëheliumââ¬â¢ and the reasons which are worth startling the public to the extent of agreeing that expensive costs be imposed on helium for the sustenance of MRIs, fiber optics, rockets, and other machines that hold special vitality in supporting human lives and activities. Where does helium come from? (in geographical, political and economic terms, as much as the chemical origins). Basically, Sun is the primary source of helium, one of the most stable elements, which is yielded through hydrogen fusion reactions in the solar system whereas on Earth, the radioactive decay of massive elements which are chiefly thorium and uranium over billions of years is found to cause helium formation beneath the Earthââ¬â¢s surface. Along with natural gas, the helium produced exudes out of large rock cavities under low pressure into the atmosphere which has approximately five parts of helium per 100,000 parts of air (Lansing, 1995). In 1868, spectrometer was first used to examine the Sunââ¬â¢s chromospheres during a solar eclipse in India where the resulting spectrum confirmed quantities of hydrogen including yellow stripes which were alleged to characterize sodium element. Unconvinced by the initial hypothesis, French astronomer Janssen further investigated on the matter and was able to disclose the truth about the stripes as beyond the traits of sodium but were most likely part of an unknown elementââ¬â¢s identity. On a separate intensive research conducted by Lockyer andà Frankland, Janssenââ¬â¢s results proved that due to its ââ¬Ëbright yellow stripeââ¬â¢, the element could not have originated from the earth after whichà Frankland proposed to call it ââ¬Å"heliumâ⬠coming from the Greek word ââ¬Å"Heliosâ⬠meaning Sun. Similar findings were revealed through a range of spectra of other stars that comp rised the yellow stripes whereas Palmieri observed them in gases erupting from Mt. Vesuvius back in 1882. It was not until 1895 that the studies of helium became more meaning when Sirà William Ramsayà treated a Norwegian ore (cleveite) with acids which yielded evolution of helium gas. Hence, the appearance of the yellowish streak in the experiment marked the certainty that on our planet, helium does exist. After nearly two decades, around the same time radium came to be known, scientists had undergone another batch of efforts that would lay foundations for an understanding of helium as a radioactive substance (Helium, History). Geographical findings indicate that the United States, specifically Texas, makes the worldââ¬â¢s largest manufacturer of helium despite the valuable presence of helium extraction facilities in Algeria, Russia, and China. Being distilled fromà the natural gasà that contains appreciable quantity of uranium and thorium to undergo radioactive decomposi tion, the helium formed is normally derived from rare circumstances of alpha-particle capture occurring underground at considerable depths (Deakin, 2010). Helium is opulently recovered from a region in Amarillo, Texas or the Texas panhandle within a perimeter of 400-km radius and this accounts for a major resource amount that sustains different parts of the world with their helium requirement (Edwards, 2004). Colorado, Kansas, and Oklahoma are also states of origin responsible for contributing small percentages of helium throughout all nations (ScienceDaily). What are the major uses of helium and why are existing reserves irreversibly declining? Several applications of Helium has have been made possible due to the elementââ¬â¢s distinct chemical and physical properties such as low boiling point, low

Infant Mortality in African American Group Essay
Infant Mortality in African American Group - Essay Example This finding means that the effect of prenatal care against no prenatal care on infant mortality rates within the first year of life is not different in African American women who have delivered live infants (Minnesota Department of Health, 2013).A study done by Centers for Disease Control and Prevention (2013) revealed that infant mortality has reduced in the United States because of the decline in neonatal deaths associated with low birth weight. The report states that prenatal smoking contributes to low birth weight that in turn leads to increased infant mortality. No matter the group involved, the report observes that intensive prenatal care helps to reduce infant mortality rates (Centers for Disease Control and Prevention, 2013).Abusalah (2012) agrees with the above study by stating that low birth weight is a critical factor related to infant mortality rates. Pollution from things such as smoking of various tobacco products and exposure to wood fuel smoke causes many women to gi ve birth to low weight infants whose life is at risk especially during their first year of life. As such, Abusalah (2012) states, ââ¬Å"Health professionals who provide prenatal care have a critical role to play in raising awareness of harms from environmental smoke exposure, especially in low income communitiesâ⬠(Abusalah, 2012).à This shows that prenatal care goes a long way in helping reduce infant mortality. Therefore, African American mothers who are provided with better prenatal care could experience lower infant mortality.

Kingdom of Life Essay
The Kingdom of Monera is the smallest in size in the biological world but are the most in terms of numbers. They can be found almost everywhere on earth. Monerans are the only kingdom of the prokaryotic type, organisms that lack a nucleus. The most common of this kind is the bacteria, which most people know are harmful for it causes illnesses and some degrees of food poisoning. The division of a single bacterium into two similar daughter cells constitutes the bacterial growth. This process is called binary fission which in turn promotes its population to grow exponentially. Bacteria are said to be the first inhabitants of Earth. Protozoa, fungus-like protists and the algae are the major categories under the kingdom of Protista. Members are categorized as colonial, unicellular or multi-cellular. Organisms under this kingdom are all eukaryotic, meaning they all have a true nucleus. Most undergo mitosis for their growth while some by meiosis and fertilization for their reproduction process. All organisms live in a water-based environment. Network forming which is called mycelia is the common process in which members of the kingdom of fungi grow. Fungi cause diseases in plant like smuts and rusts, while severe damage are from stem root and leaf rots. Most common in humans are athleteââ¬â¢s foot and ringworm among others. Animal diseases are very hard to treat because of its genetic and chemical similarity to fungi. Harmful as they may seem, some fungi members play significant roles in the ecological system. Some plants canââ¬â¢t grow without fungi. Breakthroughs in medicine are synthesized from fungi while others are used for food. The environment can not take form without plants. Humans canââ¬â¢t live without them. That is how important the kingdom of plantae is to our planet and to our lives. Said to lived 360 million years ago, plants vary in sizes, from very small kind to tall huge trees. Plants reproduce asexually and grow with the help of external factors. They are the only living organisms that are able to produce their own food through photosynthesis. Members of the kingdom Animalia are all heterotrophs. Animals, for their sustenance and survival, depends on other organisms around them. All organisms of the kingdom are eukaryotic and multicellular. Animals reproduce sexually through their special cells which when united form the zygotes that later grow into a new individual. The first recorded phyla of this kingdom was a marine specie some 542 million years ago. References: Windows Team, (1998, December 17).
