The Debate on Immigration Amnesty essays

The Debate on Immigration Amnesty essays According to William Dudley, the presence of illegal immigrants in todays America is the product of the gap between the number of people allowed to legally immigrate to the U.S. and the global demand for U.S. residency (12) which has created a huge influx of illegal aliens, especially from Mexico, into the United States within the last decade or so. This situation is supported by the findings of the Immigration and Naturalization Service (INS) which shows that between 1992 and 1998, 825,000 people on average annually immigrated and became legal permanent residents in the U.S.; however, INS figures indicate that millions of illegal immigrants without green cards or visas choose to ignore the law and melded into American society without official permission from the INS (13). Those who oppose illegal immigration maintain that these numbers are nothing short of an invasion that threatens the economic and social future of the United States; conversely, those who support illegal immigration are strongly against all efforts to deport or otherwise punish or deter illegal immigration, due to viewing such efforts as too harsh and inhumane (Dudley, 14). This raises a very important question-are these illegal immigrants victims or criminals? If they are victims, then it is clear that something is amiss in their countries of origin related to economics and politics, but if they are criminals, then they are no different from those who commit other crimes against American society. Within the last several years, a huge debate has raged concerning whether or not to grant amnesty to these victims and/or criminals, meaning that if granted amnesty, these immigrants would be allowed to remain in the U.S. and to seek out legal citizenship and permanent residence. Amnesty for illegal immigrants, also known as legal f...

Learn What pH Stands For and How the Term Originated

Learn What pH Stands For and How the Term Originated Have you ever wondered what pH stands for or where the term originated? Here is the answer to the question and a look at the history of the pH scale. Key Takeaways: Origin of pH Term pH stands for power of hydrogen.The H is capitalized because it is the hydrogen element symbol.pH is a measure of how acidic or basic an aqueous solution is. It is calculated as the negative logarithm of hydrogen ion concentration. pH Definition and Origin pH is the negative log of hydrogen ion concentration in a water-based solution. The term pH was first described by Danish biochemist Sà ¸ren Peter Lauritz Sà ¸rensen in 1909. pH is an abbreviation for power of hydrogen where p is short for the German word for power, potenz and H is the element symbol for hydrogen. The H is capitalized because it is standard to capitalize element symbols. The abbreviation also works in French, with pouvoir hydrogen translating as the power of hydrogen. Logarithmic Scale The pH scale is a logarithmic scale that usually runs from 1 to 14. Each whole pH value below 7 (the pH of pure water) is ten times more acidic than the higher value and each whole pH value above 7 is ten times less acidic than the one below it. For example, a pH of 3 is ten times more acidic than a pH of 4 and 100 times (10 times 10) more acidic than a pH value of 5. So, a strong acid may have a pH of 1-2, while a strong base may have a pH of 13-14. A pH near 7 is considered to be neutral. Equation for pH pH is the logarithm of the hydrogen ion concentration of an aqueous (water-based) solution: pH -log[H] log is the base 10 logarithm and [H] is hydrogen ion concentration in the units moles per liter Its important to keep in mind a solution must be aqueous to have a pH. You cannot, for example, calculation pH of vegetable oil or pure ethanol. What Is the pH of Stomach Acid? | Can You Have Negative pH? Sources Bates, Roger G.  (1973).

Article summary - Essay Example Based on the hierarchy of evidence, the study falls under the category of randomized controlled trials, but without definitive results. This falls in the middle of the hierarchy pyramid, midway between strong reliability and weak reliability of evidence. While the sample size of the study was small, most of the participants in the study were able to describe either one of the three methods of visits (dog visit, human visit, quiet reading session) as beneficial and even recommended them to other patients as well. The findings might very well produce the same results if given the chance to be repeated in other settings. The patients in the study were more or less similar to the patients in the PICO question. The age range of the cancer patients in the study was from 39-77 years of age, with the mean ages from 58-61 years. Johnson, R.; Meadows, R.; Haubner, J.; Sevedge, K. (2008).
