Essay --

Herman Melville, one of the more iconic names in Gothic literature, saw the world differently. Free from the Puritan rhetoric, Melville very much enjoyed the pleasures of the natural world. Melville traveled, and spent time among Natives. In several accounts he described his favorable time amongst them, and showcased the idea of noble savages beyond the borders of America. Without such tragedy to fuel him, Melville penned optimistic stories of adventure and excitement. The world wasn't a trap or a test, but a rich pearl oyster to be pursued and celebrated. True fame, or at least legacy, came later, with the publication of Moby-Dick. A darker story, but still heavy with adventure, Moby-Dick was undoubtedly a story of tragedy. Ahab, the iconic captain in the story, was driven by an obsession to hunt down a whale that injured him years prior to the story's beginning. Rather than accepting this as nature being a bit dangerous Ahab, against the better judgment of other members of his crew , anthropomorphised the titular whale, seeing it as a someone, not something, that wronged him and des...

A Matter of Time

A Matter of Time By Shashi Deshpande. Feminist Press at the CUNY, 1999. Reviewed by Sudha S. Balagopal I first read a A Matter of Time a few years ago, when it was published in India. The book made a deep impression on me, with its sensitive story of rebuilding and hope. After its more recent release in the US, I read it again, enjoying it even more. Very few books can lay claim to that fact for me. In A Matter of Time, a father, named Gopal, with three almost-grown girls, decides he has had enough of marriage and its binding ties, and walks out on his family. In a culture where marriage, to many, is the be-all and end-all of existence, where responsibilities outweigh desires, this expression to be free of all bondage in itself is strange and different to say the least (unless of course, it is for spiritual reasons). Sumi, Gopal’s wife, and his three daughters, seek shelter with her parents. Coincidentally, Sumi's parents themselves have a relationship that is more than strained. They are husband and wife in name only, inhabiting the same house with virtually no communication between the two of them. The three girls, Aru, Charu and Seema are bewildered and adrift. They all want normalcy. But what is normalcy once a father has walked out on his family? Sumi, the mother, is extraordinarily collected, to the point of indifference. How they learn to cope with this dislocation is the story that Deshpande spins for her readers. Ofcourse this is not the only story-it is also the story of all the families that are intimately linked to Sumi's. The one problem I had with A Matter of Time was the abrupt introduction of characters. Deshpande does not describe how some of the people are related to the main character as they come into the picture. In the beginning, I had a problem sorting out the various relationships. And in this I do not mean the central family of Sumi, Gopal and their three daughters. It is all the other family members: the cousins, their children, Gopal’s nephew and his wife and their children, the grandparents’ tenants and a host of others. It is said in India that when you marry a man you marry his whole family. It is the same with Deshpande’s book, where the reader is forced to accept Sumi and her entire clan, including the complex network of her relatives and well-wishers. That fact apart, Deshpande’s characters develop as you read on. The inner workings of a family are examined so clearly, making me see my own family in many parts of the book. The book is also a mirror of a society in transition. The change in Indian society is skillfully elaborated through the different generations in this book; the grandmother Kalyani who is not really educated, Sumi who is educated but doesn’t work outside the home, Sumi’s sister Premi who is a successful doctor, and the young girls Aru, Charu and Seema, who all aspire for careers and independence. The old and the new co-exist in a family that is modern, but with certain old values. With a style that is lilting and gentle, Deshpande draws us into an intricate web of family relationships, without passing judgement on any other characters' deeds. For the reader, however, there is no escaping the clutches of emotion or feeling.

Bacteria and Growth Temperature

INTRODUCTION The environments of Earth include conditions in which physical and chemical extremes make it very difficult for organisms to survive. Conditions that can destroy living cells and biomolecules include high and low temperatures; low amounts of oxygen and water; and high levels of salinity, acidity, alkalinity, and radiation. Examples of extreme environments on Earth are hot geysers and oceanic thermal vents, Antarctic sea ice, and oxygen-depleted rivers and lakes. Organisms that have evolved special adaptations that permit them to live in extreme conditions are called â€Å"extremophiles. â€Å"Photo by: Dmitry Pichugin â€Å"Thermophiles† are microorganisms with optimal growth temperatures between 60 and 108 degrees Celsius, isolated from a number of marine and terrestrial geothermally-heated habitats including shallow terrestrial hot springs, hydrothermal vent systems, sediment from volcanic islands, and deep sea hydrothermal vents. -Encyclopedia of Environmenta l Microbiology, 2002. vol. 3. Temperature and bacteria The lowest temperature at which a particular species will grow is the minimum growth temperature, while the maximum growth temperature is the highest temperature at which they will grow.The temperature at which their growth is optimal is called the optimum growth temperature. In general, the maximum and minimum growth temperatures of any particular type of bacteria are about 30 °F (-1 °C) apart. Most bacteria thrive at temperatures at or around that of the human body 98. 6 °F (37 °C), and some, such as Escherichia coli, are normal parts of the human intestinal flora. These organisms are mesophiles (moderate-temperature-loving), with an optimum growth temperature between 77 °F (25 °C) and 104 °F (40 °C).Mesophiles have adapted to thrive in temperatures close to that of their host. Psychrophiles, which prefer cold temperatures, are divided into two groups. One group has an optimal growth temperature of about 59 ° F (15 °C), but can grow at temperatures as low as 32 °F (0 °C). These organisms live in ocean depths or Arctic regions. Other psychrophiles that can also grow at 32 °F (0 °C) have an optimal growth temperature between 68 °F (20 °C) and 86 °F (30 °C). These organisms, sometimes called psychrotrophs, are often those associated with food spoilage under refrigeration.Thermophiles thrive in very hot environments, many having an optimum growth temperature between 122 °F (50 °C) and 140 °F (60 °C), similar to that of hot springs in Yellowstone National Park. Such organisms thrive in compost piles, where temperatures can rise as high as 140 °F (60 °C). Extreme thermophiles grow at temperatures above 195 °F (91 °C). Along the sides of hydrothermal vents on the ocean bottom 217 mi (350 km) north of the Galapagos Islands, for example, bacteria grow in temperatures that can reach 662 °F (350 °C). pH and bacteriaLike temperature, pH also plays a role in dete rmining the ability of bacteria to grow or thrive in particular environments. Most commonly, bacteria grow optimally within a narrow range of pH between 6. 7 and 7. 5. Acidophiles, however, prefer acidic conditions. For example, Thiobacillus ferrooxidans, which occurs in drainage water from coal mines, can survive at pH 1. Other bacteria, such as Vibrio cholera, the cause of cholera, can thrive at a pH as high as 9. 0. Osmotic pressure and bacteria Osmotic pressure is another limiting factor in the growth of bacteria.Bacteria are about 80-90% water; they require moisture to grow because they obtain most of their nutrients from their aqueous environment. Examples of Extreme Communities Deep Sea. The deep sea environment has high pressure and cold temperatures (1 to 2 degrees Celsius [33. 8 to 35. 6 degrees Fahrenheit]), except in the vicinity of hydrothermal vents, which are a part of the sea floor that is spreading, creating cracks in the earth's crust that release heat and chemical s into the deep sea environment and create underwater geysers.In these vents, the temperature may be as high as 400 degrees Celsius (752 degrees Fahrenheit), but water remains liquid owing to the high pressure. Hydrothermal vents have a pH range from about 3 to 8 and unusual chemistry. In 1977, the submarine Alvin found life 2. 6 kilometers (1. 6 miles) deep near vents along the East Pacific Rise. Life forms ranged from microbes to invertebrates that were adapted to these extreme conditions. Deep sea environments are home to psychrophiles (organisms that like cold temperatures), hyperthermophiles (organisms that like very high temperatures), and piezophiles (organisms adapted to high pressures).Hypersaline Environments. Hypersaline environments are high in salt concentration and include salt flats, evaporation ponds, natural lakes (for example, Great Salt Lake), and deep sea hypersaline basins. Communities living in these environments are often dominated by halophilic (salt-loving) organisms, including bacteria, algae, diatoms, and protozoa. There are also halophilic yeasts and other fungi, but these normally cannot tolerate environments as saline as other tax. Deserts. Deserts can be hot or cold, but they are always dry.The Atacoma desert in Chile is one of the oldest, driest hot deserts, sometimes existing for decades without any precipitation at all. The coldest, driest places are the Antarctic Dry Valleys, where primary inhabitants are cyanobacteria, algae, and fungi that live a few millimeters beneath the sandstone rock surface. Although these endolithic (living in rocks) communities are based on photosynthesis, the organisms have had to adapt to long periods of darkness and extremely dry conditions.Light dustings of snow that may melt in the Antarctic summer are often the only sources of water for these organisms. Ice. Permafrost, and Snow. From high-altitude glaciers, often colored pink from red-colored algae, to the polar permafrost, life has evolved t o use frozen water as a habitat. In some instances, the organisms, such as bacteria, protozoa, and algae, are actually living in liquid brine (very salty water) that is contained in pockets of the ice. In other cases, microorganisms found living on or in ice are not so much ice lovers as much as ice survivors.These organisms may have been trapped in the ice and simply possessed sufficient adaptations to enable them to persist. Atmosphere. The ability for an organism to survive in the atmosphere depends greatly on its ability to withstand desiccation and exposure to ultraviolet radiation. Although microorganisms can be found in the upper layers of the atmosphere, it is unclear whether these constitute a functional ecosystem or simply an aerial suspension of live but largely inactive organisms and their spores. Outer Space.The study of extremeophiles and the ability of some to survive exposure to the conditions of outer space has raised the possibility that life might be found elsewhe re in the universe and the possibility that simple life forms may be capable of traveling through space, for example from one planet to another. Research Findings Newfound gene may help bacteria survive in extreme environments Resulting microbial lipids may also signify oxygen dips in Earth’s history. Jennifer Chu, MIT News Office July 26, 2012 A newly discovered gene in bacteria may help microbes survive in low-oxygen environments.A bacterial cell with the gene, left, exhibits protective membranes. A cell without the gene, right, produces no membranes. Image: Paula Welander In the days following the 2010 Deepwater Horizon oil spill, methane-eating bacteria bloomed in the Gulf of Mexico, feasting on the methane that gushed, along with oil, from the damaged well. The sudden influx of microbes was a scientific curiosity: Prior to the oil spill, scientists had observed relatively few signs of methane-eating microbes in the area. Now researchers at MIT have discovered a bacterial gene that may explain this sudden influx of methane-eating bacteria.This gene enables bacteria to survive in extreme, oxygen-depleted environments, lying dormant until food such as methane from an oil spill, and the oxygen needed to metabolize it become available. The gene codes for a protein, named HpnR, that is responsible for producing bacterial lipids known as 3-methylhopanoids. The researchers say producing these lipids may better prepare nutrient-starved microbes to make a sudden appearance in nature when conditions are favorable, such as after the Deepwater Horizon accident.The lipid produced by the HpnR protein may also be used as a biomarker, or a signature in rock layers, to identify dramatic changes in oxygen levels over the course of geologic history. â€Å"The thing that interests us is that this could be a window into the geologic past,† says MIT Department of Earth, Atmospheric and Planetary Sciences (EAPS) postdoc Paula Welander, who led the research. â€Å" In the geologic record, many millions of years ago, we see a number of mass extinction events where there is also evidence of oxygen depletion in the ocean.It’s at these key events, and immediately afterward, where we also see increases in all these biomarkers as well as indicators of climate disturbance. It seems to be part of a syndrome of warming, ocean deoxygenation and biotic extinction. The ultimate causes are unknown. † Welander and EAPS Professor Roger Summons have published their results this week in the Proceedings of the National Academy of Sciences. This image shows that 5 different extreme environments that the extremeophile live. Such as, Sea Vennts at sea floor, Yellowstone Hotsprings, Antartica Subglacial Lakes, at Atacama Desert, and lastly at Jupiter (Space).Europa is one of Jupiter’s moons, and is covered in ice. Scientists have recently uncovered strong evidence of liquid water beneath Europa’s ice, which may be due to hydrothermal vent s, which may in turn host bacteria.

Different cinderella stories Essay

Numerous countries for countless of years have told Cinderella stories in different languages and in many different ways. These worldwide Cinderella stories may have different characters or even have different ways to interpret them. Also these Cinderella stories may have completely different magical interventions that help Cinderella throughout the story. For example the stories â€Å"Aschenputtel† and â€Å"The Twelve Months† are both a Cinderella story but have a lot of differences. Although these two Cinderella stories are not a lot alike they still have much in common. In the Cinderella story â€Å"Aschenputtel†, the girl is approached with the magical intervention of birds helping her. As for â€Å"The Twelve Months†, the girl is approached with magical intervention by the months that change the seasons for her. This magical intervention is very different from one another for these two stories even though they both involve nature. The nature plays a different type of role for each story. In â€Å"Ascheputtel† the nature is animals around her helping her, while in â€Å"The Twelve Months† the nature is Mother Nature herself helping the girl. Also one of the differences is the attitude of the stepmother and her daughters in each of the stories. In â€Å"Aschenputtel† the stepsister’s attitude is all about trying to outdo Aschenputtel band trying to force their feet into â€Å"the golden shoe† (Aschenputtel 186), so that they might marry the prince. In â€Å"The Twelve Months† the step sisters are not trying to outdo her. They simply want to be mean and cruel to her. Although these stories are very different from on another they are also alike. They both follow the five factors of being considered a Cinderella story. The five factors to be considered a Cinderella story are to have a girl that is put down, an evil influence, magical intervention, an item that identifies the girl, and the girl has to marry a prince. These factors must be met but can have various different ways to illustrate them. The first two factors are the same for both the stories because each story has a girl who is put down by the evil influence of her stepmother and stepsisters. The magical intervention is in both stories and is represented by nature. An item that identifies each girl from the stories is a little different though. In Aschenputtel the item is her shoe in which she has lost. In The Twelve Months the item is the apples. Finally the last factor is shown in both stories by marriage. Overall, Cinderella stories including â€Å"Aschenputtel† and â€Å"The Twelve Months†, have differences but in the end they all come down to the five factors. All Cinderella stories are not as different as you may think. Works Cited The Brother Grimm â€Å"Aschenputtel.†: Page 186.

Theories: Criminology and Capable Guardians

Individual Theories Maria Silva CJS/240 Farrell Binder 02/16/2013 There are several theories that influence adolescents are motivated to commit crimes, while other adolescents in similar situations are not. The theories that consist of adolescents committing crimes are based on the routine activities theory, general deterrence theory, specific deterrence theory, biochemical theory, neurological theory, genetic theory, psychodynamic theory, behavioral theory, and cognitive theory.I will talk about the routine activities theory and the general deterrence theory and focus on the bad issues in which adolescents choose to commit a crime. The routine activities theory consist of three variables; â€Å"the availability of suitable targets, the absence of capable guardians, and the presence of motivated offenders. † (Juvenile Delinquency: The Core, 2005) First, the suitable targets; homes that seem very wealthy are more easily to be the crime target. Wealthy homes can contain valuable things such as, jewelry, safe box with cash, cameras, DVD’s, and anything worth value for the offender to make quick money.It is stated that many delinquents do not like to travel to commit their crimes they look around their surroundings, and speak to other children about what they have inside their homes. This is fairly easy for delinquents to commit crimes, and engage other to join in on the crime. They look for unlock homes, expensive cars and valuables worth stealing. Second, the lack of capable parents, in which adolescents feels that if they commit a crime they will unlikely to get caught. Since they believe that their crime will not be caught by a police officer, neighbors, parents, relatives, and homeowners, they will continue to commit crimes.Adolescents or delinquents look for specific safe places to commit their crimes and go undetected from certain types of guardians. Adolescents look around and see where there’s no movement around neighborhoods, where ho mes are left unattended and these become the easy targets for the offenders. In certain neighborhoods, where society is highly, there is more monitoring from guardians such as patrolling of officers, friends, family, and neighbors are less likely to be the target of their homes, and be burglarized, and broken into. Other types of capable guardians are video cameras, and alarm systems and help capture these offenders.Third, variable for routine activities theory would be motivated offender, in which adolescents are more highly motivated to commit a crime. They consist of mostly teenage boys, and unemployment. Motivated offenders select their targets based upon on the value, visibility and accessibility. Motivated offenders may choose not to break-in an unoccupied home, because the presence of a suitable target, because he feels that a guardian, such as a neighbor may spot him, captures him, or phone an officer. Another theory that is motivated in adolescents for them to commit a crim e would be general deterrence theory.General deterrence; â€Å"concept holds that the choice to commit delinquent’s acts can be controlled by the threat of punishment. † (Juvenile Delinquency: The Core, 2005). Offenders will fear of committing crimes, if they know how severe the punishment may be, if they commit the crimes. General deterrence focusses on the prevention of crime and does not focus on the offender, but the offender receives punishment in the public eye or media in order to deter other citizens to commit crimes. As well, that general deterrence theory tries to reduce the probability of committing crimes in the general population. General deterrence results from the perception of the public that laws are enforced and that there is a risk of detection and punishment when laws are violated. † (www. sociologyindex. com) All these theories have a huge effect, routine activities theory and general deterrence theory is more important for adolescents to be aware of. For instance, general deterrence theory is effective for the public, because it shows the punishment of an offender may be and at times it can be severe, helping others not to commit the same crime or any other form of crimes.Routine activities theory are helpful, but needs more of it, for example, more patrolling officers, neighborhood watch committees, more camera surveillance, and more activates or programs for adolescents. Having these types of surveillance, might help reduce crime, because offenders would see that they are watched constantly, and might be afraid to be caught.

A comparison cultures of the Irish Travellers in Ireland, Great Research Paper

A comparison cultures of the Irish Travellers in Ireland, Great Britain and the United States and the preservation of their customs and language - Research Paper Example The common heritage will be explored first in order to discern the connection between these geographically distinct groups. A comparison across cultures will be made for various cultural aspects such as language, religion, society etc. This will aid in discerning how well preserved the Diaspora cultures are in respect to the original culture. HISTORICAL CONNECTION AND ORIGINS The origins of the Irish Travellers have been mired in mystery. Myriad theories and ideas exist as to the origin of the travellers. (Helleiner, 2003) Most scholars hold that the Travellers descended from landowners and labourers who were persecuted by Oliver Cromwell during his military campaign in Ireland. The numbers are speculated to have increased as the famines of the 1840’s forced more settled Irish people to join the ranks of the travellers. Another alternative theory sees the Travellers as a mix of Scottish Travellers and certain other gypsies from England from somewhere around the 1600’s. An even older view persists that the Irish Travellers are derivatives of nomadic groups that roamed Ireland as far back as the 5th century. By the 12th century these nomads assumed the names of â€Å"Tynkler† and â€Å"Tynker†. (O Riain, 2008) A unified social system is seen to have emerged but the exact details of such a social system remain sketchy. The Irish Travellers were not and are not a highly learned group so historical records are neither stored nor transmitted. Gaps in each of the theories presented above indicate that no theory can be seen as a culmination of the origins. Instead, the Travellers can be seen as a dynamically changing social group. Various influences such as the ones presented above have impacted the group’s cultural outlook. Changes in transport aided the Travellers in crossing regular geographical boundaries. Consequently the travellers continued to move to Britain and North America till immigration laws allowed. The resulting groups in various geographical boundaries offer commonly shared and unique perspectives that are analysed below in context of a common culture. Baseline Irish Traveller Culture The Irish Travellers are not ethnically distinct from the Irish people. Instead, the Irish Travellers are actually derived from the Irish people. However, the culture of the Irish Travellers is distinct and distinguished from regular Irish culture. The cultural development of the Irish Travellers has more or less occurred in isolation from popular Irish culture. There are streaks of some other cultural influences as listed above. These cultural influences include Christianity, Roma gypsies and localised influences on the Irish Traveller Diaspora. (O hAodha & Acton, 2007) An overview of common cultural traits of the Irish Travellers are provided below which will be used as a baseline to evaluate newer cultural developments of the Diaspora. Profession As mentioned before, the Irish Travellers were known as â€Å"Tynkers† which represents the prime profession of the travellers. The travellers were traditionally repairmen for tin pots and pans. Given that pot repair is not a regular function, the travellers would move about the countryside from settlement to settlement to repair utensils. This tendency produced a nomadic character while the profession became the identity of the trav ellers. The travellers became distinguished tin smiths but the dearth of work in one place caused them to be on the move. It is also mused that the travellers would purchase animals, often old ones in order to fulfil their nourishments needs. Thus they were also known as â€Å"knackers† in relation to their animal purchases. (Okely, 1983) Dealing in horses was a speciality of the Travellers. They
