Modesto had the highest count of homelessness with 983 documented homeless individuals according to a 2015 Modesto Bee study and sadly, the amount increases as surrounding areas begin to enforce strict laws.

Amanda Cross and the Female Sleuth Free Essays

string(30) " well as types of characters\." Merriam-Webster dictionary defines sleuth as a slang word for sleuthhound or detective who follows a trail to uncover a mystery, crime or unknown variable. In literature mystery is defined as a distinct subgenre of detective fiction in which an unknown event, often a disappearance or murder, causes the stories protagonist, or main character in the story, to solve the crime or mystery. Mysteries do not require crimes or the assistance of law enforcement as the common detective fiction or whodunit but they do depend on an unknown variable that the protagonist must determine, (NationMaster, 2003). We will write a custom essay sample on Amanda Cross and the Female Sleuth or any similar topic only for you Order Now Mystery fiction is not a new genre of story telling. Throughout time man has been interested in solving the riddles of life. So much so that there is significant evidence to indicate that civilization has enjoyed a good mystery as far back as Ancient Egypt and Greece. However, it was Edgar Allan Poe and his first published story The Murders in the Rue Morgue published in the mid-nineteenth century that made mystery fiction the popular brand of novel it is today. The Murder in the Rue Morgue first appeared in Graham’s Magazine, (Mystery Network, n. d. ). After Poe there have been a number of influential mystery writers including Wilkie Collins, also known as the father of the mystery, and Sir Arthur Conan Doyle, the Scottish author of the Sherlock Holmes series. Sherlock Holmes is not only one of the most widely known mystery series but is also considered to be the most famous literary figures in history, (Mystery Network). Holmes was first introduced to readers in The Strand Magazine when they published the story â€Å"A Study in Scarlet. † Edward Stratemeyer, the author of both the Hardy Boy’s and Nancy Drew series of juvenile mysteries, Carolyn Keene and Agatha Christie. Amanda Cross is a twentieth century mystery writer who contributed much to the genre. Her semi-feminist voice transformed the common sleuth from a run-of-mill private detective into a strong willed female literature professor. Cross, who was struggling with gender equality issues at the University of New York, was tired of the tried and true mystery novels that were being produced a-dime-a-dozen. She set out to produce mysteries are intelligent and contain a role model worthy protagonist. Cross is the pen name of Carolyn Heilbrun. Her first novel, In the Last Analysis, features Kate Fansler, the female sleuth featured in a 14 book series. Fansler is a witty and highly educated literature professor at the prestigious New York University and the majority of her adventures are set against an academic background. Fansler, as opposed to traditional detectives, solves the crime through interviews and conversations with those involved. Most of the mysteries involve the death of either a student or professor and it is up to Fansler to solve the crime. In The Last Analysis, Fansler recommends Janet Harrison see psychoanalyst Dr. Emmanuel Bauer. Bauer is a friend and former lover of Fansler’s. However, shortly after starting sessions with Bauer, Harrison is found shot to death on his couch. Fansler is on the case to prove that her friend is innocent. However, Harrison has led an elusive life in which she has very few friends or acquaintances, making it hard for Fansler to track down a possible killer. However, Fansler’s knowledge of Freudian concepts and her personal integrity helps her to catch the killer. Although Heilbrun strays from the norm her first novel is typical of an amateur-detective mystery. Fansler knows a crime has been committed. She seeks information pertinent to the case by following leads and seeking information from those involved. Fansler then comes up with a theory about what happens, which proves to be correct. Also typical is the fact that the protagonist is a strong female character. Throughout Heilbrun’s novels Fansler is portrayed as strong independent woman, much like Heilbrun. She enjoys eating and drinking and marries later in life. Fansler differs from a majority of female protagonists in mystery fictions because she solves the mystery through Freudian analysis and personal interviews. This is a mystery of the mind in which Fansler does not have physical clues that lead her to find the real killer. Other mystery writers have used female protagonists as well. Contemporary author Nevada Barr features the female protagonist Anna Pigeon, a national park ranger who leads the reader through various adventures in the backcountry solving mysterious deaths. Pigeon is similar to Fansler in the sense that they are both independent modern women. They are both professionals who solve mysteries within the backdrop of their chosen profession. Pigeon and Fansler both represent strong female characters. Yet, Pigeon represents a more traditional character in modern mystery fiction since she follows a trail of clues left behind by the murders as opposed to using literary and psychoanalytical clues to solve the mystery. Similarly well known mystery writer Sue Grafton began her alphabetical mystery series with A is for Alibi. In her mystery fiction protagonist Kinsey Malone represents a courageous and sassy female private eye. Grafton too takes a more traditional approach by utilizing a private investigator as the main character. Others authors such as Sandra de Helen utilize logic and facts to solve mysteries as opposed to following physical clues. De Helen’s novel The Hounding features two female detectives Shirley Combs and Mrs. Mary Watson. De Helen has a series planned surrounding the two who is in some way related to Sherlock Holms and his assistant Watkins and they solve crimes similarly. These characters all follow typical mystery genre traditions. But not all mystery writers follow tradition. Sue Grafton, a well known mystery writer, started an alphabetical mystery series in which murders are solved by a female feline and a small dog. Grafton strays away far from tradition with characters but stays within the realm with the practices that her characters use to unravel the crimes. Different writers use different methods of crime solving as well as types of characters. You read "Amanda Cross and the Female Sleuth" in category "Papers" However, there is a pattern of female mystery writers creating professional and strong female protagonists. Most of the main characters in modern mystery writers today have had to overcome obstacles in a male-dominated world. They often face gender discrimination or stereotypical peers that create obstacles that must be overcome. For example, Ellen Godfrey’s protagonist Jane Tregar is tough and feisty. Tregar, a professional working in a search firm, has had to battle her way up the corporate ladder to a senior position in an executive firm. She utilizes technical know-how to uncover information and corporate savvy to survive her male peers and their scrutiny as well as solve mysteries and be successful in the male-dominated business world. Another modern author Sara Paretsky, currently extremely popular with mystery readers, has created the protagonist V. I. Warshawski. Warshawski broke ground as the first female in an all male dominated world of the dangerous back streets of Chicago. Warshawski proves that women can be tough and sensitive and that physical difference between men and women do not mean that women are not capable of performing well in dangerous situations. In the Last Analysis, Fansler fully understands the plight of women within the world of academia. â€Å"Kate was startled by Professor Anderson, who was an eighteenth-century man with a strong distaste for all female writers since Jane Austen (Cross, 2001, p. 3). † This is a common war in the literary department. Literature has been male dominated for a number of years. This is caused in large by the fact that women were not taught to read or write for centuries. However, as women have begun to take their seat at the head of English departments across the nation male peers may scoff. There is a large portion of male literary enthusiast who tries to minimize the female impact on literature today. Heilbrun later retired early from her post at the University of New York to avoid dealing with this same type of professional peer. But gender discrimination and differences are not the only ones that haunt Heilbrun. Age also seems to be a factor. Heilbrun laments that her students are young and full of life and the longing for their own futures. However, as a professor years goes by and nothing changes. â€Å"Spring on an American campus, even an Urban a campus as this one, inevitably drove the faculty into a mood of lassitude, irritation and fastidiousness. Perhaps it is because we are getting old, while the students, like the Caesar’s crowds on Appian Way, are always the same age. Gazing at the students who sprawled or made love on every patch of available grass, Kate longed, as she did every spring for a statelier, less untidy era, (Cross, 2001, p. 3). † Heilbrun used Fansler to express her own apprehensions about aging as well as the endless cycle of youth that professors endure each college enrollment period. Heilbrun did not reveal her herself as the author of the Amanda Heilbrun mysteries until she was offered tenure at the University due to her fear of criticism from her peers and having her literary work interfere with her academic work. However, age criticism may have also been a concern. The idea of age is transcendent in Heilbrun’s mysteries. Fansler is already in her forties at the start of In the Last Analysis and has never been married nor does she have children. Although latter in the series she does marry she has no concerns about being a â€Å"homemaker† or playing into any other typical stereotypes of women. In fact Fansler, although discreet, has a number of lovers. The idea of the woman as a non-maternal figure breaks social traditions. But the primary social concern of In the Last Analysis surrounds professional ethics and human integrity. Throughout Heilbrun’s series there are two main characters, Fansler and her friend and future husband Reed Amhearst. Fansler is old-fashion yet she has a penchant for martinis and she comes from a background of wealthy parents to supplement her teacher’s salary. This is convenient since she does not seem to work much as she uncovers her friend’s innocence. As she tries to prove her friends innocence she solicits the help of Amhearst, an attorney, who goes out of his way to help Fansler and repay her a favor. Amhearst is portrayed as Fansler’s love interest and a protect figure. Throughout the book, In the Last Analysis, Amhearst tries to caution the headstrong Fansler who gets involved despite his warnings. Fansler even goes so far as to put her reputation and career on the line to prove that Bauer, her friend, is innocent. Her old-fashion sensibilities coupled with a reckless and courageous manner makes Fansler a great candidate to become an amateur sleuth and enforce the idea of human integrity. There are several other examples of human integrity in the book as characters assist Fansler in solving the case. Heilbrun’s novels have been successful overall. However, she was criticized. Especially for her first book, In the Last Analysis, in which it is obvious that Heilbrun has yet to fine tune her technique. Although professional news agencies such as The New York Times had positive reviews a number of readers felt Heilbrun tried to hard to present Fansler as smart and independent. Thus she came across as being pretentious. However, after her first novel the series gained in popularity in part due to the fact that her subsequent novels take place within the world of academia and Fansler’s character can put her intellect to better use. In conclusion, Heilbrun has made a significant contribution to the mystery fiction genre. She is the first mystery writer to create a mystery in which the crime must be solved using conversations and analytical skills as opposed to physical clues and traditional evidence. Heilbrun also sets the stage for female authors who create strong and independent protagonists that break the mold of female stereotypes. In keeping with many other female authors Heilbrun’s female protagonists are working in a professional field despite gender inequalities. Throughout In the Last Analysis and other Heilbrun novels there are overtones of age related issues as well as gender differences within the world of academics. Both may reflect challenges that Heilbrun has faced as a Professor at the University of New York. Heilbrun utilizes a common amateur-detective mystery technique yet she strays from the norm by implementing psychoanalytical methods of solving the crime as opposed to relying entirely on physical clues. In addition to concerns about professional ethics, specifically within the medical field in which patient-client relationships come into question, there is a predominant theme of personal integrity. Integrity is often displayed throughout the novel in the form of personal favors and character’s taking risks for each other. Fansler is able to solve the crime using intelligence, Freudian analysis and a little help from her friends. Variations from the common mystery novel include the use of wit and analytical strategies to solve the case as well as the protagonist being an older woman without cause to seek out marriage or family life. Heilbrun and many of her peers have chosen to expand the image of â€Å"detective† to include smart and professional women who are employed outside of the law enforcement or private investigation fields. Although Heilbrun’s protagonist is similar to the main characters in other mysteries by her peers, Heilbrun deviates by choosing to make Fansler an example of a non-traditional woman. She is neither interested in marriage or children and has taken a number of lovers to prove her modern values despite an old-fashion background. Heilbrun paved the way for female mystery writers as well as the female protagonist. Through her popular series and the popularity of Kate Fansler a whole new genre of mystery books has evolved. These new series feature witty story lines and fast paced plots while featuring strong protagonists and often feminist views. After Heilbrun’s success there have been a number of other mystery writers following similar strategies including Nevada Barr, Rita Mae Brown and Sue Grafton. References Cross, A. (2001).

Operating in Australia the Great Barrier Reef †Free Samples

Question: Discuss about the Operating in Australia the Great Barrier Reef. Answer: Running for a stretch of a staggering 2300 kilometers, ornamenting the north eastern coastal region of Australia the Great Barrier Reef, is a natural wonder that fascinates anyone who is a travel enthusiast. It is situated in the state of Queensland near the Equator. True to the name this marine ecosystem is comprised of almost 2900 individual reefs along with approximately 900 individual islands. It serves as a habitat for innumerable flora and fauna which attract thousands of tourists to the reef on a daily basis. The reef has been deemed as World Heritage Site by UNESCO in the year 1981 (Great Barrier Reef 2017). It has been found that over the years due to the rise in tourism there is a depletion of the ecosystem. This north east region of Australia is a tourist hub, which attract national and international tourists every year. A large part of the government income is incurred the hospitality and tourism industry. With the encouragement and increase of tourism this natural beauty has been subjected to a lot of change and degradation, hence the Australian Commonwealth Government wanted to protect and conserve the ecosystem and has in turn set up The Great Barrier Reef Marine Park in 1975 (gbrmpa.gov.au, 2017). The sectors of income in the reef region can be generated from Commercial fishing and aquaculture, Tourism industry, hospitality and recreation along with research and development. In the tourism department there are various types of business that has popped up which is adding to the economy of the area and is helping the local population to grow and develop. Some of the popular business in tourism is hotel business, restaurant business, boating etc. But one of the most profitable and advantageous businesses that are possible in the barrier reef owing to its geographical location and technologies now available is snorkelling (Day and Dobbs 2013). All adventure fanatic tourists who are looking for an adrenaline rush opts for snorkelling in the Great Barrier Reef region when they are visiting the island country. This is also the best and the closest option one can choose to fully imbibe the beauty of this natural ecosystem. Snorkelling allows an individual to closely see and feel the marine life. Anyone who can swim and has minimum physical fitness is eligible for swimming. There are various options to choose from, depending on the location where one is staying; there are options where a person can dive out of a boat. In this case the boat owner, the boat driver, the instructors are all involved in the business and are earning from what an individual is spending on that trip (Wilson and Verlis 2017). Most of the time people who come for the snorkeling or diving experience do not have any knowledge about the sport. Hence there are instructors who are appointed to give people diving lessons and teach them how to use the gear and signal under water, anticipation of problem under water and how to avoid them etc. there are luxury and ordinary options to choose from. The divers who assist the people in the ride are all certified and are experienced in the sport. The companies who arrange fro the diving and snorkeling have boats and cruises which take tourists on rides and mostly all of these activities come in a package (Lamb et al. 2014). This industry is fully dependent on the marine ecosystem and human resource. A tourist would always want to only go for such a nerve racking experience with someone who is certified to carry out such tasks and hence skilled trained human resource is a very important factor. There are also several safety measures that are to be taken. Another important aspect of this industry is the gears that are used during snorkeling or scuba diving. This includes a whole industry in itself and several numbers of people are involved in manufacturing and retailing these gears (Amelung and Nicholls 2014). The snorkeling and scuba diving industry in the island country of Australia is one of the most relevant and booming business industries with a lot of prospect with the growing technical development and popularity of the adventure sport among the tourists. To help tourist gather the most from their vacation to Australia the government has also come up with many laws which each of these companies have to abide by and follow strictly. With the advancement of technology this industry has also grown exponentially creating several job opportunities for the localities in and around The Great Barrier Reef. One of the most important drawbacks of this business is that most people are not up for such adventure sport hence people usually opt for a much more relaxing option to spend their stay in the reef islands. It is an adventure sport and is for the people who are looking for the thrill and rush. References: Amelung, B. and Nicholls, S., 2014.
