Teen Pregnancy Research Paper - 1273 Words
The Effects of Pregnancy Among Adolescent Girls Heather Thedford HS 2013: Health Communications Texas Womanââ¬â¢s University DESCRIPTION Teenage pregnancy is defined as a teenage girl, usually within the ages of 13-19, becoming pregnant (Unicef 2008). These are young girls that have not yet reached adulthood, who are engaging in unprotected sex and have conceived a child from that encounter. Risk Factors Associated with Teen Pregnancy Teen pregnancy has severe health risk factors for the teen mother and for the unborn child as well. Research shows that teen mothers are less likely to get proper prenatal care. Resulting in babies that are more likely to be born prematurely or of low birth rate. This can cause ââ¬Å"chronic respiratoryâ⬠¦show more contentâ⬠¦In 2015, the national teen birth rate for non-Hispanic white females was 90,833. The teen birth rate for non-Hispanic black females was 50,039. Along with the teen birth rates for Hispanic 80,364, American Indian/Alaska Native 4,738, and Asian/Pacific Islander 4,297. The national percentage of teen pregnancies to girls under the age of 15 was 1 percent. Girls age 15-17 was 26 percent and girls age 18-19 was 73percent. Texas is 5th in the nation when it comes to birth rate for teen pregnancies. In 2015, the number of teen births in Texas was 32,687. That is 34.6 births per 1,000 women. This is an 8 percent decrease from Texasââ¬â¢s peak in 1991 at 56 percent. As you can see, Texasââ¬â¢s teen birth rate is slightly higher than our countryââ¬â¢s average birth rate of 22.3 per 1,000 women. Texas is ranked 46th on a scale of 1 (lowest) to 50 (highest) in teen birth rates and teen pregnancy rates. The number of teen pregnancies in Texas by race/ethnicity in 2015 are just as diverse. Teen pregnancy to Non-Hispanic White females was 7,376. Teen pregnancy to Non-Hispanic Black female was 4,619. Teen pregnancy to Hispanic was 22,745. Teen pregnancy to American Indian/Alaska Native was 127 and Asian/Pacific Islander was 267.

Self-help groups are one of the most popular forms of group therapy. One of the most known self-help groups is Alcoholics Anonymous also known as A.A. Alcoholics Anonymous (AA) is an international organization produced to assist alcoholics to recover and live alcohol free lives. It was founded by Bill Wilson and Robert Holbrook Smith in 1935.

I noticed that the participants did not look like what I perceived someone who was suffering from alcohol dependence would look like. They looked like productive law-abiding citizens. I am embarrassed to say that it never occurred to me that these individuals could live positive lives while battling alcoholism. I assumed that they would be dysfunctional and incapable to participate in the meeting. Instead many of them looked healthy and were eager to engage in the group discussion. We began the meeting by introducing those who are new to AA or those who were visiting from a different group. If a person did not want to introduce themselves, they were not made to do so. The meetings were very calm and were conducted in an orderly fashion. In a support group, the leader should create a safe environment where members can share (Jacobs et al., 2012 p. 43). I felt very comfortable being there and even though I was there as an observer, the group leader always encouraged me to ask questions or comments. Regardless of the topics that were discussed, no one was judgmental. I believe the positive energy I felt while in the group was because everyone truly cared about each otherââ¬â¢s sobriety.

We will write a custom essay sample on Money or any similar topic only for you Order Now Explain your reasons for this rating. If I had to rate my feelings for speaking in front of an audience, I would have to say that I would give it a five on a scale from one to 10. The reason I say this is because I donââ¬â¢t love speaking in front of an audience, but I also donââ¬â¢t hate it either. I would say that I am very comfortable speaking in front of people and I feel that I do extremely well. I feel that I speak very well and I am very sure of myself when speaking in front of others. Also, Just because I do have the ability to do so does not mean that I Just love to be in front of an audience speaking. I donââ¬â¢t get nervous or feel uncomfortable when I have to speak in front of the class or an audience. So, I would have to say that I am pretty neutral on the topic, I donââ¬â¢t hate it and I donââ¬â¢t love it. .2 What type of public speaking, if any, makes you uncomfortable? I am not sure what yap of public speaking that would make me uncomfortable, because I have not had to do anything other than speak in front of an class or at work. I think if I had to decide than I would Have to say that I think if I had to speak in front of thousands of people I would feel a bit uncomfortable only for a short minute and then I would eventually relax. I would only feel that discomfort then is because the thought of all those people giving me their attention would overwhelm me. After, I could grasp that whole concept , I feel like I would be fine and more confident. My confidence would increase oleo because of the attention that I would be getting from my audience. So I guess no type of public speaking would have me terrified for a long period of time. As time would progress throughout my speech, I would find my confidence. .3 What type of public speaking, if any, do you enjoy most? I would to say that I am neutral on this topic, I donââ¬â¢t hate it but I donââ¬â¢t love it.

(EconLib, 2002) For most people, whether in the I-JK or the US, the working class were really Working classââ¬â¢, even though Jobs were developing the intensity of the Job was not lessened, they were indeed laborious. As the years went on, leading from the early ages of industrial work, developing into the current year 2013 much has changed. We will write a custom essay sample on Money or any similar topic only for you Order Now Till now legislations have been passed in order for all employees to have rights within the organisation that they work, Rights such as Equal Pay, Sex Discrimination, Race Relations, Gender Recognition amongst many since as early as the 1970ââ¬â¢s. (University of Bradford, 2010) Through such laws being passed, men and women are able to work side by side , earn fair pay and have the same standing as man within the working society, though even through these laws, discrimination of sexes is still large and racism is still a factor. Individuals differ, and very much so, through ethnicity, physique, gender, family experiences, motivation, attitudes and personality. (Laurie J Mullins, 2010, Chapter 4) ââ¬ËSensitivity to individual needs and differences, especially in terms of their resilience, becomes particularly significant, when organisations embark on change initiatives. Such changes may lead to new mind sets, new attitudes and new perceptions that enable people to cope and adjust to the different worldââ¬â¢. Laurie J Mullins, 2010, Chapter 4) Peopleââ¬â¢s perception of the working environment has changed so much that for an employer to create a scenario of discrimination is no longer a laughing matter, employers must approach every situation with such sensitivity, they have to consider how people react to situations and how they can deal with individuals as opportunities and as the company changes, especially when culture also happens to e a factor as mentioned by Schein, ââ¬Ëa pattern of basic as sumptions-invented, discovered or developed by a given group as it learns to cope with its problems of external adaptation and internal integrationââ¬â¢. Laurie J Mullins, 2010, Chapter 6) In Hugh Collins book ââ¬ËEmployment Law, he states how the employment rights act has paved the way for so many other rights such as anti-discrimination, trade unions and human rights. Through this we can understand that it is due to such laws amongst many others that organisations are literally forced into including rights for people they would not have thought of, and the law that assembles all the issues together is the Equality Act f 2006, where it is stated that there must be equality and human rights, discrimination unlawful on grounds of religion, belief, education etc. nd to create public authorities to create equal opportunity between men and women. (University of Bradford, 2010) These laws have been passed continuously throughout the decades in order to allow the greater populace, ever growing in numbers and diversity to engage in work, so they are not heckled at as they choose to earn and make a living for themselves. Each law holding a certain purpose has not only paved the way for diversity in race and eligion, but fundamentally in gender, which has been the concern even till now. How these acts are implemented in the working environment is the most interesting thing, from the advertising to the selection of a person. For example many years back a well renowned advert had been broadcast for some time, by Howard Brown, an employee of Halifax Banking, turned actor to promote his organisation. He was promoted in order to promote. There are many examples like this which allow for diversities to be represented in a positive light, something that wasnââ¬â¢t witnessed even a decade ago. Job descriptions have become broader, allowing anyone to apply, by the 1900-2005 racism was still rifled in parts of Europe, especially the I-JK and France, according to a BBC online survey made in 2002, 40% of black people say that they had witnessed racism in a place ot employment, double the tgure tor white people. Looking at t you could it can be noted that even now this number though may have decreased it is still relevantly at an all-time high. Within the selection process, through the advance of educational equality, all generations of people are now educated, hence the growing number of unemployed, eople both educated high or at a lower level are struggling to secure Jobs, this nearly almost causes an issue in selecting Just the right person for the Job, one may have one good image but lack in other etc. There is something called the ââ¬ËHalo Effectââ¬â¢, this is where if we see them first in a good side it becomes difficult to recognise the bad side in them, for example noticing a personââ¬â¢s glowing eyes as being the factor for someoneââ¬â¢s employment rather than them having what it takes to hold the occupation. The Economist, 2009) In conclusion, looking through the laws that have been passed and the decisions aken to improve on how people are employed through fair recruitment and equality of opportunity is that it allows for greater sympathy to people who want to work, it has now developed into a liking to employ a diverse group, the public eye is ever present on what actions a company takes with its employees and how it runs itself. Organisations do the best they can to apply fair rules and run the company through the passed laws as it shows they are willing to experience each member of its team and become more adaptive in how it deals with its staff. The better they do internally the better they are presented externally. How to cite Money, Papers

Cathode Ray Tube free essay sample
Do you like watching television? I love it. I do not know what would I do if televisions did not exist. It is interesting, in several years, they have become a huge part of our lives, our indispensables. J. J. Thomson was inspired by some scientists and he provided us the opportunity of having televisions in our lives. Also other scientists improved his thoughts and experiments which leaded to the invention of the television afterwards. It is not that simple of course. Letââ¬â¢s look at the backstage By the beginning of the 20th century, there were some problems that had not been solved. The main problem was; not being able to understand the structure of matter. If the structure of the matter could be solved, all the other problems could be solved too. Thatââ¬â¢s why the major part of the scientists were trying to understand the details about the matter. First atomic theory, which was based on experimental observations, was produced by John Dalton in 1808. His theory was consisted of the following: * all matter is made up of atoms, * atoms are indivisible and can neither be created nor destroyed, all the atoms of an element are identical * compounds are formed by the chemical combination of atoms in small whole number ratios. Dalton called these groups as ââ¬Å"compound atomsâ⬠which we call ââ¬Å"moleculesâ⬠today. Today, we know that atoms are divisible and that all atoms are not the same, there are isotopes in the nature. So, John Dalton was wrong in some ways. Although some parts of his theory were wrong, we can say that Dalton was successful since he could explain the structure of matter for the first time. By this theory, he also helped and inspired J. J. Thomson to do a brilliant experiment which in this case concerns us deeply, since it laid the groundwork for invention of television. Keeping Daltonââ¬â¢s atomic theory in mind, in 1897, J. J. Thomson made an experiment which helped the scientists to learn more about atom and improve the scientific information. The experiment was on the rays that were produced by making a cathode ray tube. ââ¬Å"Cathode ray tube is also known as a television picture tube, it is also used for visual display in oscilloscopes and radar systems. On the neck of the tube, there is an electron gun that ends electrons that pass through a control grid a focusing anode (-) . A second anode speeds the electrons as the beam passes. After the beam passes through the second anode, it is deflected in one of two ways: electrostatically or magnetically. Magnetic deflection is used in radar display tubes and most of the television display tubes. The cathode ray tube screen is coated with a phosphor chemical. The coating converts the energy of the electron beam into visible light and presents a visual display. â⬠1 If we summarize, cathode ray tube is a type of vacuum tube that uses electrons to produce an image on a screen. By using this kind of cathode ray tube, J. J. Thomson discovered the negative charges in the atom, and he called them in his own way, but as a matter of fact he has found the ââ¬Å"electronsâ⬠. George Stoney had thought the existance of them in 1891, but he was unable to prove. Then, Thomson thought that; as electrons have negative charges, but atoms are neutral, there should be some positive charges somewhere in the atom. Also, as electrons are much smaller and lighter than atoms, those positive charges should be much heavier than electrons. Therefore, Thomson made an atom model that seems like a plum pudding. Also, by finding this, he has found H+ ion which helped him to realise that atom could be divided. This showed that, John Dalton was wrong by saying that atom could not be divided into small pieces. This also proved that all atoms were not the same and John Dalton was wrong again. J. J. Thomson has won the 1906 Nobel Prize for his ââ¬Å"Cathode Ray Tube Experimentâ⬠. Thomson was wrong in some parts like Dalton. Thomson thought that ââ¬Å"electrons move randomly in the atom,â⬠however today we know that they are on the orbitals. Despite Thomsonââ¬â¢s success in so many ways, there were some thoughts left unproved. These thoughts were proved by some experiments. In 1906, R. A. Milikan measured the charges of electrons and as a result, he proved Thomsonââ¬â¢s thought: electrons covered just a little part of the atom (plum pudding model). Afterwards, Ernest Rutherford made an experiment called ââ¬Å"Gold Foil Experimentâ⬠in 1911. He sent alfa rays onto the gold atoms, and he saw that the rays were coming back. So, he realised that there were some positive charges in the centre, and he called these positive charges, which Thomson thought of their existance, ââ¬Å"protonsâ⬠. By this way, Rutherford has found that the nucleus of atoms consists of protons. However, there was a question which was not answered: why did not the electrons fall onto the nucleus by the attraction of protons? In 1913, a student of Rutherford called Neils Bohr, thought that electrons had certain energies (quantum), and that they were moving. By the year 1922, Bohr and Arnold Sommerfeld has explained that the first shell had 2, and the second one had 8 electrons. As one shell gets full, the electrons locate into the other shell. Also, the chemical properties were explained according to the last shell. The elements in which the last shell is full, do not get into reactions, and the others give or take electrons to make their last shells full. The periodic table was arranged by the elementsââ¬â¢ mass numbers, but this time it was rearranged according to the atom numbers. However, there was occured another question that was not answered: why are there 2 electrons in the first shell, and 8 electrons in the second shell? As nothing has an end, science doesnââ¬â¢t have too. Each day some new things are added to life. Chemistry is the same. Starting from early years until today, chemistry is trying to be solved by all the scientist. Although these successful scientists above have accomplished so important things, there are still some things unknown that are going to be certainly solved in the future. Over a hundred years ago today, Thomson made the ââ¬Å"Cathode Ray Tube Experimentâ⬠. With the huge help of his experiment, science has extremely improved. After he accomplished the experiment, with the help of the data that he collected and with the things he had discovered, scientists made other discoveries that are very useful today. Another thing is, we can watch television now by the help of cathode ray tubes. Televisions have become our indispensables. We almost arranged our lives according to them. Now, we can learn everything about the world from televisions, we can watch films or programmes that entertains us, we can even order food or pay the bills from televisions! It is really amazing. I think we should thank
