National Geographic Photography - Dissertation Example Founded in 1888, the National Geographic Society, publishers of National Geographic Magazine, developed its mission, which is "for the increase and diffusion of geographic Knowledge." (â€Å"Penn Museum Presents in Focus 2005). More than a century later, they are still fulfilling this mission of bridging the differences in our world, drawing our large world a little closer, and reminding us that all humans have the same basic needs no matter where we live. Through photographs that capture the very essence of human beings, they have managed to achieve their goals and have an effect on society in an amazing way. â€Å"The images in the exhibition also speak to the magazine's shifting role in society during a century of war, peace, and rapid technological and cultural change. Images from the 1930s and 40s, for example, reveal the magazine's efforts to divert attention away from the hardships of domestic life during the Great Depression and World War II.† (Penn Museum Presents in Focus 2005). Explorers Hall is the name of The National Geographic Society Headquarters. The building takes up an entire block and yet it can hardly contain the items, photos, and all that makes up the National Geographic Magazine and what it represents and has accomplishes. The National Geographic Society has ventured from photography and publication to education, multimedia, philanthropy, and so much more.

Technology and Law Enforcement Essay Example for Free

Technology and Law Enforcement Essay This system provides rapid collect and retrieval of data about wanted fugitives, locating stolen property, locating missing people and protecting law enforcement and the public (Siegel amp; Worrall, 2012). The FBI maintains the host computer that provide telecommunication network to the CJIS Systems Agency in every official state (Mass. gov website). Automated Fingerprint Identification System (AFIS) Automated Fingerprint Identification System is a type of biometric system that uses a digital imaging to capture a fingerprint that can be compared to a database records to determine a person identity (webopedia). The use of AFIS is growing in the United States This system can classify fingerprints and identify 250 characteristics of the print. AFIS use high speed silicon chips to plot each and every detail and count the number of ridges in a person’s fingers and palm (Siegel amp; Worrall, 2012 pg. 195). I fingerprints 25 to 35 inmates a day on AFIS and it a wonderful tool because with a couple of minute their fingerprint will be sent to Washington D. C and I can identify the person and have their whole entire criminal history. Combined DNA Index System (CODIS) In the late 1980s, the federal government laid the groundwork for a system of national, state, and local DNA databases for the storage and exchange of DNA profiles. This system, called the Combined DNA Index System (CODIS). CODIS is a computerized database that allows deoxyribonucleic acid (DNA) obtained at a crime scene to be searched electronically to find matches among sample taken from convicted offenders and crime scenes (Siegel amp; Worrall, 2012 pg. 97). In the late 1980s and early 1990s, states began passing laws requiring offenders convicted of certain offenses to provide DNA samples. Currently all 50 states and the federal government have laws requiring that DNA samples be collected from some categories of offenders (justice. gov). Since 2011, my agency started collecting DNA from inmate that was arrested for crimes New Technology 3 against a person such as; rape, homicide, aggravated battery and aggravated assault etc. But now FDLE had added Burglary, grand theft and trespassing. When we reach 2020, no matter what category that an offender in e every offender will have to summit a DNA sample for their crime. Once CODIS make their improvements, DNA evidence will help solve and may even prevent some of the Nation’s most serious violent crimes.

The Natural Violence of Human Nature as Shown Through the Epic Beowulf

The Natural Violence of Human Nature as Shown Through the Epic Beowulf Violence is the way of the game in the world of Beowulf. It is how things get done. It is what people care about. The songs in the Mead Hall are all sung of the great violent epics that took place in the times long gone. When there is no violence that can be perpetrated, these cultures tell stories of violence, so as to release this need for aggression that is somewhere deep with in them. This is in many ways like the world that we live in. Humans in this modern world are surrounded and fascinated by violence. Whether or not they are taking part in it, it does fascinate them. It can be found in television, movies, video games, music, books, and all other forms of cultural expression. Our fascinations have not changed that much in the last 1700 years, they have just gained more sophistication and technology. In the days of Beowulf, they sang songs and told epics of the battles and conquest long passed. That was there way of building a heroic nature to their famous warriors. The bards would go out and compose epic ballads in the memory of fallen soldiers and of the great conquerors. Now instead of court bards, we have men like Stephen Ambrose. Instead of the ballad of Sigmund and the dragon, we have D-day. As the men in the Heorot told great tales of battle, bravery and death, we make video games. Video games serve to purposes that both derive straight from our violent nature. They are entertainment and a way to release our natural aggression. Of course they sell so well with young adults. In our modern society violent action against one another is heavily regulated. It is hard for us to release our pent up aggression without invoking the l... ...ommander of the Allied Expeditionary Force, architect of D-Day, and President, Arnold Schwarzenegger, the Govenator and even the current frontrunner for the Republican Presidential nomination, John McCain. We still find confidence in leaders who have proven themselves in combat. The legacy Beowulf leaves behind is that of a great and powerful warlord. Violence is what is seen and told in the stories of his greatness. It is barely mentioned that he was a great ruler for fifty years of peace. This is completely forgotten in the histories. What is remembered is his great battles, because human nature is fascinated with violence. It still is today. The top grossing video game is Halo 3, a game which?s entire game play is warfare. Of the top three grossing movies of all time, two are violent Epics. Violence has and probably will always fascinate human society.

Billie Holiday Biography

Billie Holiday (born Eleanora Harris (1915–1959) was an African American jazz singer and songwriter. Her singing style, strongly inspired by jazz musicians, lead to a new way of using word choice and rhythm. A critic named John Bush once wrote that Holiday â€Å"changed the art of American pop vocals forever. † She only co-wrote a few songs, but a number of them have become jazz standards that many musicians strive to live up to.Some of these standards were set by songs of hers such as â€Å"God Bless the Child†, â€Å"Don't Explain†, â€Å"Fine and Mellow†, and â€Å"Lady Sings the Blues†. She also became famous for singing â€Å"Easy Living†, â€Å"Good Morning Heartache†, and â€Å"Strange Fruit†, a protest song  which became one of her standards and was made famous with her 1939 recording. In Harlem she started singing in various night clubs. Holiday took her professional pen name from  Billie Dove, an actress she admired, and the musician Clarence Holiday, thus was born â€Å"Billie Holiday†.The producer  John Hammond arranged for Holiday to make her recording debut, at age 18, in November 1933 with Benny Goodman, singing two songs: â€Å"Your Mother's Son-In-Law† and â€Å"Riffin' the Scotch. † The latter being her first big hit. â€Å"Son-in-Law† sold 300 records,  but â€Å"Riffin' the Scotch,† sold 5,000 records. Hammond was very impressed by Holiday's vocalization style. He said of Holiday that, â€Å"Her singing almost changed my music tastes and my musical life; because she was the first girl singer I'd come across who actually sang like an improvising jazz genius. Hammond compared Holiday positively to Armstrong and said she had a good sense of lyrics at her young age. In early 1959 Holiday found out that she had  cirrhosis of the liver. The doctor told her to stop drinking, which she did for a short time, but soon returned to heavy drinking . Some of her friends tried to get her to check into a hospital, but she did not go. On May 31, 1959, Holiday was forcibly taken to Metropolitan Hospital in New York suffering from  liver  and  heart disease.She was arrested for having drugs with her as she lay dying, and her hospital room was invaded by the police. Police officers were stationed at the door to her room because of her drugs. Holiday remained under police guard at the hospital until she died from  pulmonary edema  and  heart failure caused by cirrhosis of the liver on July 17, 1959. In the final years of her life, she had been gradually tricked out of her earnings because of her drug and alcohol addictions. She died with seventy cents in the bank and seven-hundred fifty dollar tabloid fee.

Progesterone For Maintenance Tocolytic Therapy after Threatened Preterm Labour Essay

What was the sampling technique used and what are the advantages and disadvantages of using that technique? The researchers used a two-stage sampling method that was non-random in the first stage and randomized in the second stage. The total population was made up of 137 patients who were admitted for preterm labour. Selection from this initial population was non-random because there were exclusion criteria. The seventy women included were randomised to their treatment groups by assigning randomly generated numbers. The main advantage of using the technique was its simplicity and straightforwardness. Every individual who fit the inclusion criteria had equal chance of being selected. The disadvantage of the technique was that there was bias in the initial selection. Such bias could have affected the accuracy of the experiment. Was there randomisation? There was randomisation in the second stage of sampling, where all those women who fit the inclusion criteria were part of the sampling population. Randomisation was done by generating random numbers and assigning numbers to the women included in the study. Was it biased? There were several sources of bias in the study. The fact that the patients were all from the same clinic is already in itself introducing bias. The study was not double blind, which could also be a source of bias. The use of exclusion criteria in the first stage of sampling lessened the bias. In the second stage of sampling, efforts were done to further remove bias by assigning treatment to all included patients. No patient also left the study, thus further reducing bias. Describe the validity and power of the study Based on the researchers’ desired results, the statistical power of the study for improving latency was initially calculated be 80% with an assumption of getting standard deviation (SD) of 12 days at 5% level of significance. However, when their results came out, the power was calculated to be lower (value for this was not presented in the paper). By checking the means and SD for latency, and assuming a two-tailed analysis, power was calculated to be 51% only. This could be attributed to the high standard deviation that could in turn be due to the relatively small number of samples tested. In other similar studies, the sample population is much higher. For example, another study testing the effect of vaginal progesterone on preterm birth used 413 women (Eduardo B. Da Fonseca, et al. , 2007). Despite the low statistical power, the results presented here are valid as preliminary data on the supplementation of tocolytic therapy with vaginal progesterone to control preterm labour. The study was able to show that progesterone treatment had an effect on the other outcomes that were measured (please refer to Table 2 in the text). Background information of the hypothesis Progesterone is a steroid hormone that is widely used in hormone replacement therapy in menopausal women. It is also used to induce menstruation in women who suddenly stop menstruating. Its capacity to control preterm labour was first reported in the 1980s. Oral administration of progesterone induces side effects like migraine, dizziness, vomiting and blurred vision. This was the usual mode of administration of progesterone, which was proven effective to reduce preterm labour (Meis, et al. , 2003). Since 2003, studies have reported on the use of progesterone vaginal suppository to treat preterm labour (E. B. Da Fonseca, Bittar, Carvalho, & Zugaib, 2003) and even in high risk women (Eduardo B. Da Fonseca, et al. , 2007). Until this current study, there were no previous reports on the use of progesterone to supplement tocolytic therapy, using magnesium sulphate and intravenous ampicillin, on women who actually had preterm labour. Hypothesis of the study Null hypothesis: The use of vaginal progesterone after inhibition of preterm labour will not change latency period and recurrence of preterm labour. Alternate hypothesis (what the study really wants to prove): After the inhibition of preterm labour, treatment with vaginal progesterone will result in increased latency period and decreased recurrence of preterm labour. Methodology The study was conducted on 70 women who were had arrested uterine activity after they were treated for premature labour. The women were randomized to two groups; one was administered vaginal progesterone and the other, a placebo, until delivery. Subjects were monitored for days to latency until delivery, recurring preterm labour and other primary and secondary outcomes. Different statistical tests were used to determine if the treatments resulted in significantly different outcomes. Comparisons were done using Student’s t-test for quantitative data; chi-square and Fisher exact tests, among others, were used for categorical data. Conclusion of the study The study concluded that the use of vaginal progesterone after tocolytic therapy was effective in increasing latency to delivery but not in decreasing the incidence of recurrence of preterm labour. Is it a valid assumption based on the data of the study? Describe the applicability and relevance of the paper to clinical practice. The conclusion is valid based on the data of the study. The paper and the results presented are applicable and relevant to clinical practice because it proposes a new means of treating preterm labour for increased latency. Although the recurrence of preterm labour appeared not to be reduced with the treatment, this could be due to the advanced stage of the pregnancy when the preterm labour occurred or due to the small sampling population. It is significant to note that this is the first to report on the supplementation of tocolytic therapy with vaginal progesterone. Further studies can also be done to validate the results.

Womens Roles in America in the Early 1800s

Women's Roles in America in the Early 1800s In the early 19th century in America, women had different experiences of life depending on what groups they were part of. A dominant ideology at the beginning of the 1800s was called Republican Motherhood: middle and upper-class white women were expected to be the educators of the young to be good citizens of the new country.   The other dominant ideology about gender roles that was common in the first half of the 1800s in white upper and middle-class circles was that of separate spheres: women were to rule the domestic sphere (home and raising children) and men the public sphere (business, trade, government). This ideology would have, if followed consistently, meant that women were not part of the public sphere at all. But there were a variety of ways that women did take part in public life. Biblical injunctions against women speaking in public discouraged many from that role, but some women became public speakers anyway. The end of the first half of the 19th century was marked by several woman’s rights conventions: in  1848, then again in 1850.  The Declaration of Sentiments of 1848 describes clearly the limits placed on women in public life before that time. African American Women and Native American Women Women of African descent who were enslaved had no real public life. They were considered property and could be sold and raped with impunity by those who, under the law, owned them.  Few participated in public life, though some came to public view. Many were not even recorded with a name in the records of the enslavers. A few participated in the public sphere as preachers, teachers, and writers. Sally Hemings, enslaved by Thomas Jefferson and was almost certainly his wife’s half-sister, was the mother of children most scholars accept Jefferson fathered. Hemings came to public view as part of an attempt by a political enemy of Jefferson to create a public scandal. Jefferson and Hemings themselves never publicly acknowledged the relationship, and Hemings didn’t participate in public life other than having her identity used. Sojourner Truth, who was emancipated from slavery by New York’s law in 1827, was an itinerant preacher. At the very end of the first half of the 19th century, she became known as a circuit speaker and even spoke on women’s suffrage just after the first half of the century.  Harriet Tubman’s first trip freeing herself and others was in 1849. Some African American women became teachers. Schools were often segregated by sex as well as race. As one example, Frances Ellen Watkins Harper was a teacher in the 1840s, and also published a book of poetry in 1845.  In other free black communities in northern states, other African American women were able to be teachers, writers, and active in their churches.  Maria Stewart, part of Boston’s free black community, became active as a lecturer in the 1830s, though she only gave two public lectures before she retired from that public role.  Sarah Mapps Douglass in Philadelphia not only taught but founded a Female Literary Society for other African American women, aimed at self-improvement. Native American women in some nations had major roles in making decisions of the community.  But because this didn’t fit the dominant white ideology that was guiding those who were writing history, most of these women are unnamed in history.  Sacagawea is known because she was a guide for a major exploratory project, her language skills needed for the success of the expedition. White Women Writers One area of public life assumed by a few women was the role of a writer. Sometimes (as with the Bronte sisters in England), they would write under male pseudonyms and sometimes under ambiguous pseudonyms.  Margaret Fuller not only wrote under her own name, but she also published a book on Women of the Nineteenth Century before her untimely death in 1850.  She had also hosted famous conversations among women to further their â€Å"self-culture.† Elizabeth Palmer Peabody ran a bookstore that was a favorite gathering place for the Transcendentalist circle.   Women’s Education In order to fulfill the aims of Republican Motherhood, some women gained access to more education so- at first- they could be better teachers of their sons, as future public citizens, and of their daughters, as future educators of another generation. So one public role for women was as teachers, including founding schools.  Catherine Beecher and Mary Lyon are among notable women educators. The first African American woman to graduate from college did so in 1850. Elizabeth Blackwell’s graduation in 1849 as the first woman physician in the United States shows the change that would end the first half and begin the second half of the century, with new opportunities gradually opening for women. Women Social Reformers Lucretia Mott, Sarah Grimkà ©, Angelina Grimkà ©, Lydia Maria Child, Mary Livermore, Elizabeth Cady Stanton, and others became publicly active in the abolitionist movement. Their experience there, of being put in second place and sometimes denied the right to speak publicly or limited to speaking to women, helped lead some of these same women to work later for women’s emancipation from the â€Å"separate spheres† ideological role. Women at Work Betsy Ross may not have made the first United States flag, as legend credits her, but she was a professional flagmaker at the end of the 18th century. She continued her work through several marriages as a seamstress and businesswoman. Many other women worked in various jobs, sometimes alongside husbands or fathers, and sometimes, especially if widowed, on their own. The sewing machine was introduced into factories in the 1830s. Before that, most sewing was done by hand at home or in small businesses. With the introduction of machines for weaving and sewing fabric, young women, especially in farm families,  began to spend a few years before marriage working in the new industrial mills, including the Lowell Mill in Massachusetts. The Lowell Mill also channeled some young women into literary pursuits and saw what was probably the first women’s labor union in the United States. Setting New Standards Sarah Josepha Hale  had to go to work to support herself and her children when she was widowed. In 1828, she became the editor of a magazine that later evolved into Godeys Ladys Magazine, and was billed as  the first magazine edited by a woman for women ... either in the Old World or the New.  Ironically, perhaps, it was Godeys Ladys Magazine that promoted the ideal of women in the domestic sphere and helped establish a middle and upper-class standard for how women should carry out their home life. Conclusion Despite a general ideology that the public sphere should be exclusively male, some notable women did participate in public affairs.  While women were prohibited from some public jobs- such as being a lawyer- and were rarely accepted in many others, the women of the early 1800s had public roles. Some women worked (enslaved, as factory workers, at home and small businesses), some women wrote, and some were activists.

haydn essays

haydn essays Among the influential composers of classical music, there have been few who have contributed so much in both talent, creativity, and style as Joseph Haydn and Ludwig Van Beethoven. Both extremely talented in the art of classical composition, Haydn and Beethoven placed their heart, soul and ingenuity in their music as is clearly illustrated in Haydns The Creation and Beethovens The Creatures of Prometheus. Both composers display sheer genius in their very effective ways of displaying complex themes through their musical works - in this case, the concept of creation is common to both pieces under study. Haydns connection to the concept of Genesis and its subtleties is quite evident thought his entire composition. Looking at Haydns religious piety and as some would argue, unrealistic optimism, it is only fitting that Haydn expressed the concept of creation as an oratoria, which is the biblical counterpart to opera; instead of the various propounded themes of then-contemporary opera, the underlying theme is strictly of biblical concepts and stories. The opening pitch and dynamic of the work are absolutely equal. The overture is introduced in fortissimo and without vigor. The possible reason for such a SLOW pace was to make it hard for the listener to ascertain a steady pulse. In aiming for such ambiguity, Haydn intentionally fails to express a definite key, chord or melody in the first few bars, and as a result the listener is met with a rather formless initial introduction. Upon the completion of those initial bars of music, the listener is thrown a stray of fragment! ed melodies with no cadence. The normal convention of tonality is cleverly ignored by Haydn. It is quite interesting to note that the piece ends in an unusual way; he lands it on C minor, an avant garde practice created only a short time earlier by Mozart. The use of mutes throughout the entire beginning and of a blank unison C without order seem to ...
