Free Essays on Welfare Mothers

In the article â€Å"Incarcerated Mothers† a lot of valid points and strong arguments are made. We learn in the beginning of the article that majority of the women in prison are mothers, and their needs are often neglected. Women’s healthcare needs and services are often ignored compared to male inmates. Majority of women mothers take care of themselves and abide by the rules simply to get out of prison as soon as possible so that they can see their children. Would it be a different case if we were discussing fatherhood? Yes, I think it would. For instance, incarcerated males receive many of the necessary services, such as, medical, dental, recreational, vocational, and educational services. However, does the male population of inmates deserve to have these benefits? I think that the men take advantage of these benefits. I do not think the main thing on their mind is getting out of prison to see their children. Many of them may not even know they have kids, they may be in jail for sexual abuse and therefore not care about their offspring. For instance, on page 262 the given quote is saying that men get in trouble for more harsh things, they try to escape, they don’t wear the proper clothes that they are supposed to, they get in fights with one another, and are rowdy compared to the women who abide by the rules and are quite so that they can go home and see their families. Clearly, if men are acting in such a manner then they are not concerned about acting properly in prison so that they can get out and get back to their families. Fathers in prison don’t necessarily have to prove themselves worthy of fatherhood, they don’t have to prove competency. Where as mothers have to prove this without expecting support for their mothering role. It is terrible to see that men don’t have to work as hard to get out to see their children. Both genders should have to equally prove themselves worthy of being a parent rather than t...

pH, pKa, and the Henderson-Hasselbalch Equation

pH, pKa, and the Henderson-Hasselbalch Equation The  pH  is  a measure of the concentration of hydrogen ions in an aqueous solution. pKa (acid dissociation constant) is related, but more specific, in that it helps you predict what a molecule will do at a specific pH. Essentially, pKa tells you what the pH needs to be in order for a chemical species to donate or accept a proton. The  Henderson-Hasselbalch equation describes the relationship between pH and pKa. pH and pKa Once you have pH or pKa values, you know certain things about a solution and how it compares with other solutions: The lower the pH, the higher the concentration of hydrogen ions, [H]. The lower the pKa, the stronger the acid and the greater its ability to donate protons.pH depends on the concentration of the solution. This is important because it means a weak acid could actually have a lower pH than a diluted strong acid. For example, concentrated vinegar (acetic acid, which is a weak acid) could have a lower pH than a dilute solution of hydrochloric acid (a strong acid). On the other hand, the pKa value is a constant for each type of molecule. It is unaffected by concentration.Even a chemical ordinarily considered a base can have a pKa value because the terms acids and bases simply refer to whether a species will give up protons (acid) or remove them (base). For example, if you have a base Y with a pKa of 13, it will accept protons and form YH, but when the pH exceeds 13, YH will be deprotonated and become Y. Because Y removes protons at a pH greater than the pH of neutral water (7), it is cons idered a base. Relating pH and pKa With the Henderson-Hasselbalch Equation If you know either pH or pKa you can solve for the other value using an approximation called the Henderson-Hasselbalch equation: pH pKa   log ([conjugate base]/[weak acid])pH pkalog ([A-]/[HA]) pH is the sum of the pKa value and the log of the concentration of the conjugate base divided by the concentration of the weak acid. At half the equivalence point: pH pKa Its worth noting sometimes this equation is written for the Ka value rather than pKa, so you should know the relationship:   pKa -logKa Assumptions That Are Made for the Henderson-Hasselbalch Equation The reason the Henderson-Hasselbalch equation is an approximation is because it takes water chemistry out of the equation. This works when water is the solvent and is present in a very large proportion to the [H] and acid/conjugate base. You shouldnt try to apply the approximation for concentrated solutions. Use the approximation only when the following conditions are met: −1  Ã‚  log ([A−]/[HA])  Ã‚  1Molarity of buffers should be 100x greater than that of the acid ionization constant Ka.Only use strong acids or strong bases if the pKa values fall between 5 and 9. Example pKa and pH Problem Find [H] for a solution of 0.225 M NaNO2 and 1.0 M HNO2. The Ka value (from a table) of HNO2 is 5.6 x 10-4. pKa  Ã‚  Ã¢Ë†â€™log  Ka  Ã‚  Ã¢Ë†â€™log(7.4Ãâ€"10−4)  Ã‚  3.14 pH pka log ([A-]/[HA]) pH  Ã‚  pKa  Ã‚  log([NO2-]/[HNO2]) pH  Ã‚  3.14  Ã‚  log(1/0.225) pH  Ã‚  3.14  Ã‚  0.648  Ã‚  3.788 [H]  Ã‚  10−pH  Ã‚  10−3.788  Ã‚  1.6Ãâ€"10−4 pH, pKa, and Henderson-Hasselbalch Equation Key Takeaways The pka is the pH value at which a chemical species will accept or donate a proton.The lower the pKa, the stronger the acid and the greater the ability to donate a proton in aqueous solution.The Henderson-Hasselbalch equation relates pKa and pH. However, it is only an approximation and should not be used for concentrated solutions or for extremely low pH acids or high pH bases. Sources de Levie, Robert. (2003).

Nursing Practice Act Assignment Example | Topics and Well Written Essays - 750 words

Nursing Practice Act - Assignment Example Nursing regulations will be up to date and cover emerging issues because the nursing board constantly reviews the various professional needs and makes, modifies, or repeals the rules and regulations where necessary. Nurses will need to adhere to the rules and regulations from the BON and constantly seek guidance from the board on unclear matters in nursing practice. The board of nursing has the power to approve the training programs for nurses. Upon initial and subsequent assessment of the nursing programs, the board can either approve, reject or withdraw an approval. The NPA guides decision-making processes on whether to approve or reject a nursing program. The curriculum of the program has to meet certain standards (Russell, 2012). This will enhance quality in the training of nurses and increase the number of competent nurses. The availability of well-trained nurses promotes professionalism in the workplace and the provision of quality nursing care. Nurses will check institutions b efore enrolling for nursing programs to ensure they have the rquisite approval by the board. The NPA ensures the protection of the public against unqualified persons by setting titles and licensing qualified nurses (Russell, 2012). The titles are Registered Nurses (RNs), and the Licensed Practical/Vocational Nurses (LPN/VNs). This will enhance quality in the training of nurses and increase the number of competent nurses. The availability of well-trained nurses promotes professionalism in the workplace and the provision of quality nursing.

Financial crisis regulatory Essay Example | Topics and Well Written Essays - 2000 words

Financial crisis regulatory - Essay Example Robert Shiller examined the controversy of the global economic crisis and its management and raised prudent arguments about the practice. The economist argues that democratization of finance provides an ideal strategy of managing the contemporary and future economic crisis. Some analysts support Shiller’s perspective while others have criticized his ideology. Interestingly, few economists argue that the financial regulations adopted by the OECD countries are sufficient in containing financial crisis (Gray & Akseli, 2011 p. 2). Considering the magnitude of the idea of global financial crisis management, there is a need of developing knowledge of ideal approaches of managing the problem. This article provides an analysis of the debate started by Shiller concerning democratizing finance while comparing the argument with the types of regulatory measures practiced by the OECD countries. The Shiller’s perspective on financial crisis Shiller explores the importance of moral re putation of finance institutions in management of economic crisis. After the 2008 global economic recession, anger expressed itself in objections around the world. People constantly criticized how powerful profit oriented social-economic procedures have influenced financial institutions. The Occupy movement staged serious actions challenging the relationship between the government and businesses. A clear insight was that individuals responsible for the crisis would revitalize their moral reputations by adopting acceptable financial procedures (Kroszner, Shiller & Friedman, 2011 p. 4). Shiller has popularized an idea that economists need to reclaim the finance for the common good instead of condemning it. He argues that finance is a powerful tool that the society can utilize in solving its problem and in developing its general welfare. The global economy needs more finance but not less and the finance should facilitate the attainment of the society’s goals (Tropeano, 2011 p. 5 ). Consequently, the analyst emphasizes the need of rethinking about finance and its responsibility in the society. Particularly, Shiller claims that financial management should not merely include the manipulation of money or control of risks but should mainly involve the stewardship of community’s assets. The economist highlights how individuals serving in the financial careers can manage, safeguard and increase the public assets. Moreover, the analyst explains how finance has contributed to the good of the society through inventions, savings accounts, mortgage and pensions. Consequently, Shillers insists that economists and policy makers should devise new strategies for rechanneling financial creativity to benefit global economies (Princeton University, 2012 p. 1). Previous regulations schemes have targeted restricting the financial sector by slowing down the development of lending or trading. However, Shiller’s alternative believes that this ideology is unproductive especially in the current dynamic industry that presents high degrees of dynamism. The Shiller’s model values the importance of creativity, personal morality, education and effect of finance on the people’s lives (Princeton University, 2012 p. 1). Shiller supports the present financial regulation system arguing that although the system is imperfect, it plays a significant role in stabilizing the global economy.

A Tale Of Two Schools: How Poor Children Are Lost To The World Essay

A Tale of Two Schools: How Poor Children Are Lost to the World   Ã‚  Ã‚  Ã‚  Ã‚  Jonathan Kozol wrote a book titled Savage Inequalities: Children in America’s Schools. A Tale of Two Schools: How Poor Children Are Lost to the World is an excerpt from the book. The excerpt tells the story of two high schools in the Chicago area.   Ã‚  Ã‚  Ã‚  Ã‚  The Chicago area has a variety of high schools. Du Sable High School in Chicago and New Trier High School in a Chicago suburb are at different ends of the spectrum when speaking of the overall quality of education. New Trier has seven gyms and an Olympic pool. Du Sable is crowded into one city block while New Trier takes up as much space as a small college.   Ã‚  Ã‚  Ã‚  Ã‚  The courses at New Trier are completely geared for college bound students. For example, there are seven foreign languages offered there. With that in mind, try to understand that while the seniors at New Trier study authors such as Freud and Nietzsche, the seniors at Du Sable are just now learning how to read four syllable words. Only about seventeen percent of Du Sables students are in a college preparation program. No wonder the graduation rate, Kozol states, is twenty five percent at Du Sable.   Ã‚  Ã‚  Ã‚  Ã‚  The outcome of the twenty five percent graduation rate is clear to all that live in the neighborhood. In his book, Kozol quotes a reporter asking a sixteen-year-old dropout about how much she would like to ...

Josh Hutcherson Essay

Josh Hutcherson Not Afraid to Be Himself Many celebrities to this day are recognized for their scandalous acts and wrong doings. Not many people stay true to themselves in today’s society, even less are willing to donate their time and money to help others that need it. Josh Hutcherson is one of these people in others eyes, he has always been himself either on set of a movie or at home with his loved ones. As a child he had to deal with the lose of both of his uncles, they died from AIDS during the height of the epidemic. â€Å"They were n their early thirties, in great shape, but unfortunately they were taken away from us too soon. Both passed away at about the time I was born. † (Hutcherson). Though he didn’t get a chance to meet his uncles, he saw how this affected the rest of his family and from that point on he wanted to make sure that they wouldn’t die in vain. Josh Hutcherson is a hero to many for his desire to help others, always staying true to himself, and donating his time and money to charities. Josh Hutcherson was born in Union, Kentucky as an only child and at the age of four his ounger brother was born. Shortly after he started to become interested in acting and being on television, his parents figured it was just a phase like most children would have. Over the years his fascination with acting grew stronger to his mothers surprise and she eventually decided to help him pursue his goal so at the age of nine josh and his family moved to California. After getting settled down josh started auditioning for roles and landed very few, very minor parts. But with his determination he landed a role in ER in 2003 ( Anonymous , 2012) . From that point on josh’s acting areer took off and he starred in many TV shows and some small movies. After â€Å"Bridge to Terabithia† was released he was a highly regarded actor and many studio s wanted him to fill in roles. He quickly made friends that had the same lifestyle and views as himself, one of the most prominent was Avan Jogia. Avan founded the organization called SBNN (Straight But Not Narrow). Avan, an actor, musician, writer, and big picture thinker. His idea, his passion and his voice started it all. Seeing the hardships young adults face, both in and out of school, ignited his desire to take a stand against ullying. (anonymous) Josh knew he wanted to be a part of something great and became a part of the group and helped spread the message. Actors today are usually fake and doing what their name implies, acting. Yet, some do stay true to their ways and don’t let all the fame and attention sway them. Hutcherson is a perfect example of this. You can see that even in his movies the roles he plays are true to his own personality, some stars that have worked with him on set have said that even offstage he has the same nice, boyish charm that his characters have in movies. Ever since he was nine and started acting he has always been himself even tho most studios and sponsors want him to act fake and perfect he wants to always stay true to himself and not ever put on an act just to please someone else. Being yourself with all of the stress and publicity is an extraordinarily large task and many fail to do so. But Hutcherson is one of the few that have rose above the others and proved himself as a strong idividual As a small child Hutcherson had a very strong personality and always spoke his mind, this characteristic has stuck with him his whole life and he is still the same way to this day. So when something wasn’t right, Hutcherson would not hesitate to speak up. Because of the death of his uncles to AIDS and how they were treated for being homosexuals he hated when someone treated anyone like they didn’t matter. He hated bullying and whenever he hears about it or witnesses it, he feels the strong need to do something. Hutcherson clearly expresses his feelings towards gays being bullied for who they like, Josh Hutcherson received the Van Guard award at the GLAAD Media Awards for his help to stop gay bullying( Giannotta, 2012) . Helping others that are being bullied or that need someone there or him have just been natural to Hutcherson. Because of Hutcherson family history with homosexuality he had very strong views on gay rights and equality of all people. He decided to join his friend Avan Jogia and his organization â€Å"Straight But Not Narrow†, this was a group dedicated to opening the eyes of others to the fact that we shouldn’t care wh o a person dates, its about the persons personality and actions(Jogia, 2011) . He became the main advocate for the group and has been the most active member since the start. But Hutcherson has done more deeds outside of SBNN as well. On June 3, 2012 Hutcherson took place in a charity celebrity picnic where many popular stars and actors come together and throw a picnic. This even has raised more than $33 million since 1989 to fund pediatric AIDS research and the Foundation’s international medical programs to prevent new HIV infections in babies and to keep HIV-positive mothers alive through lifesaving treatment (anonymous, 2012). Hutcherson has done a lot of things to help kids and even adults in need since his career took of, making him a hero to many people who know of the actors deeds.
