ES Cells essays

Ideas for My Paper/ ES Cells essays Embryonic stem (ES) cells are considered the ultimate stem cell because of their dual ability to proliferate and to differentiate into all the cells and tissues of the body. But they are ethically contentious because five-day-old embryos have to be destroyed to derive them. Adult stem cells show promise as an ethically preferable alternative, but scientists have not been able to show that they are as versatile as ES cells. The two papers featured in this web focus highlight the promise of both avenues of research, one describing a kind of adult stem cell that may turn out to be just as versatile as ES cells, and the other showing that ES cells can generate neurons to effectively treat symptoms of Parkinson's disease in a rat model. Now, Catherine Verfaillie and her colleagues at the University of Minnesota, Minneapolis, have isolated an adult stem cell from cultured human, rat and mouse bone marrow mesenchymal stem cells, called MAPCs - for mesenchymal adult progenitor cells. Like ES cells, these cells multiply indefinitely in culture. Injected into mouse embryos, the mouse cells differentiate into most, if not all, of the cell types in the body. In a separate paper, Ron McKay and colleagues at the National Institute of Neurological Disorders and Stroke, Bethesda, Maryland, show that mouse ES cells be used in cell replacement therapy in an animal model of Parkinson's disease. From cultured ES cells, the group generated a large supply of neurons that produce dopamine. The neurons functioned normally and gave clear behavioural responses when grafted into the brains of rats that model Parkinson's disease. Together the papers show two different approaches for isolating powerful, pluripotent stem cells with clear therapeutic potential. However many fundamental questions remain about how ES cells and MAPCs function in a biological context, and how they can best be harnessed for medical benefit. It will be exciting to watch the ans ...

Day of the Dead

Day of the Dead At first glance, the Mexican custom of the Dà ­a de Muertos- the Day of the Dead- may sound much like the U.S. custom of Halloween. After all, the celebration traditionally starts at midnight the night of Oct. 31, and the festivities are abundant in images related to death. But the customs have different origins, and their attitudes toward death are different. In the typical Halloween festivities, which are of Celtic origin, death is something to be feared. But in the Dà ­a de Muertos, death- or at least the memories of those who have died- is something to be celebrated.  The Dà ­a de Muertos, which continues until Nov. 2, has become one of the biggest holidays in Mexico, and celebrations are becoming more common in areas of the United States with a large Hispanic population. Its origins are distinctly Mexican: During the time of the Aztecs, a monthlong summer celebration was overseen by the goddess Mictecacihuatl, the Lady of the Dead. After the Aztecs were conquered by Spain and Catholicism became the dominant religion, the customs became intertwined with the Christian commemoration of All Saints Day. Specifics of the celebration vary by region, but one of the most common customs is the making of elaborate altars to welcome departed spirits home. Vigils are held, and families often go to cemeteries to fix up the graves of their departed relatives. Festivities also frequently include traditional foods such as pan de muerto (bread of the dead), which can conceal a miniature skeleton. Here is a glossary of Spanish terms used in connection with the Day of the Dead: los angelitos  - literally, little angels; young children whose spirits returnla calaca  - a skeleton figure representing death, similar to the Grim Reaperel calavera  - a reckless fellowla calavera  - skullla calaverada  - crazy, foolish behaviorel difunto  - the departedla hojaldra  - a bread for the Day of the Deadla ofrenda  - an offering left for the souls of the deadzempasà ºchitl  - the traditional name for the yellow marigolds used to mark a pathway to the altar Childrens Books for Day of the Dead Day of the Dead Day of the Dead Free Online Research Papers Latin Americans celebrate a holiday every year where they honor their dead by decorating skulls. The holiday focuses on the gathering of family and friends to remember people that were close to them. The Day of the Dead (El Dà ­a de los Muertos), is a holiday celebrated in Mexico and by Latin Americans living in the United States and Canada. The holiday focuses on gatherings of family and friends to pray for and remember friends and family members who have died. Celebrations occur on November 2 in connection with the Catholic holidays of All Saints Day (November 1) and All Souls Day (November 2). Traditions connected with the holiday include building private altars honoring the deceased using sugar skulls, marigolds, and the favorite foods and beverages of the departed, and visiting graves with these as gifts. Due to occurring shortly after Halloween, the Day of the Dead is sometimes thought to be a similar holiday, although the two actually have little in common. The Day of the Dead is a time of celebration, where partying is common. The Day of the Dead celebrations in Mexico can be traced back to the indigenous cultures. Rituals celebrating the deaths of ancestors have been observed by these civilizations perhaps for as long as 2500–3000 years. In the pre-Hispanic era, it was common to keep skulls as trophies and display them during the rituals to symbolize death and rebirth. The festival that became the modern Day of the Dead fell in the ninth month of the Aztec calendar, about the beginning of August, and was celebrated for an entire month. Festivities were dedicated to the god known as the Lady of the Dead, corresponding to the modern Catrina. In most regions of Mexico, November 1 honors children and infants, whereas deceased adults are honored on November 2. This is indicated by generally referring to November 1 mainly as Dà ­a de los Inocentes (Day of the Innocents) but also as Dà ­a de los Angelitos (Day of the Little Angels) and November 2 as Dà ­a de los Muertos or Dà ­a de los Difuntos (Day o f the Dead). People go to cemeteries to communicate with the souls of the departed, and build private altars, containing the favorite foods and beverages, as well as photos and memorabilia, of the departed. The intent is to encourage visits by the souls, so that the souls will hear the prayers and the comments of the living directed to them. Celebrations can take a humorous tone, as celebrants remember funny events and stories about the departed. Plans for the day are made throughout the year, including gathering the goods to be offered to the dead. During the 3-day period, families usually clean and decorate graves; most visit the cemeteries where their loved ones are buried and decorate their graves with offerings, which often include orange Mexican marigold which is a bouquet usually consisting of 20 or so flowers. In many American communities with Mexican populations, Day of the Dead celebrations are held which are very similar to those held in Mexico. In some of these communities, such as in Texas and Arizona celebrations tend to be mostly traditional. For example, the All Souls Procession has been an annual Tucson event since 1990. The event combines elements of traditional Dia de los Muertos celebrations with those of pagan harvest festivals. People wearing masks carry signs honoring the dead and an urn in which people can put slips of paper with prayers on them to be burned. Therefore, the day of dead brings families together to remember the people that were close to them.

Asymmetric Information Essay Example | Topics and Well Written Essays - 500 words

Asymmetric Information - Essay Example The various forms of asymmetric information include adverse selection, cost monitoring and moral hazard. (Bebczuk, 2003).The financial market is mostly affected by any of these forms which in turn lead to problematic financial transactions. Asymmetric information leads to various problems out of which the opportunistic behavior is the most risky situation. Opportunistic behavior is a situation in which executives and managers of a company tend to differentiate the information. The original information is conveyed in two different ways to the people working in the organization and to the outsiders. (Karuratna, 2000).This is done to improve their contacts and financial transactions through which they can maximize their utilization of funds. This in turn affects the investors as they are not provided with proper information. Since the information is misinterpreted by the managers it leads to the predicament called as the opportunistic behavior. (Sharpe, 1990).The managers make use of this opportunity and their reported earnings get gradually increased. The opportunistic behavior shows desire of the managers and their urge to move on with the financial transactions. Managerial discretion may add up to the already sustainin g problems there by resulting in loss to the people involved in the contract. In addition to that, it eventually increases discretion among the managers which also leads to loss in the amount of shares. (Sun, 2008).The shareholders tend to invest more money in a particular company and managers take advantage of this situation. In a competitive financial market, opportunistic behavior poses greater risk to exporters as well as the party involved in transaction. The terms of contract are also not specified properly in the financial document. There are also two types of opportunistic behavior prevalent in financial markets. Opportunism

In what ways does the Ara Pacis Augustae reflect Augustus' vision of a Research Paper

In what ways does the Ara Pacis Augustae reflect Augustus' vision of a Roman 'golden age' - Research Paper Example The reconstructed Ara Pacis now stands within a large, reinforced glass and concrete shelter, also the work of Mussolini’s architects, designed to protect it from the elements and pollution(1). Marble surfaces of the box—shaped Ara Pacis are covered with relief sculpture carved in white marble. The artists are unknown, but the level of craftsmanship is exceptionally high, ending archaeologists to suggest that they may have been Greeks, or at least Greek—trained artists(2). As with much ancient Greek sculpture, Reliefs were originally painted, which would have made the stand out much more clearly than they do now. 1. Rehak,P.’Aene or Numa?

The artists of the Ara Pacis:the process of Hellenization in Roman relief sculptures(Chapel Hill, 1997). Fig: Ara Pacis Original Frontal View (13-9 B.C) Source http://www.vroma.org Fig.: Present s tatus of Ara Pacis after some modification Source http://www.vroma.org Physically weak and plagued by ill health, Agustus was only eighteen years old when Julius Caesar's assassination thrust him, as his uncle's chief heir and adopted son, into the forefront of the subsequent political and military turmoil. He outmaneuvered and outfought rivals such as Cassius, Brutus, Lepidus, Mark Anthony, and Cleopatra. Augustus embodied and represented the tremendous currents that transformed Rome from a small Italian city situated on the Tiber River to a powerful empire that bestrode the known world as no other colossus ever had. Augustus was astute and artful enough to balance republican traditions with imperial realities, skillfully maintaining the delicate facade to achieve his goals, so that, late in life, he could rightfully claim it(3). In general, the Augustan system worked fairly well, in fact, it lasted more than 200 years. It provided a material and political base of cultural achievem ent that rivaled the Greeks under Pericles(3). This is the age of the Pax Romana, the Roman Peace. But the Augustan reforms were not limited to political, economic and social issues alone. They also envisioned a fundamental change in Roman culture itself. Augustus tried to turn Rome into a world capital and taught the Romans to identify their destiny with the destiny of all mankind. They were the chosen people who would bring peace and stability to a violent and changing world. The transformation which he tried into Rome was not only administrative or political but it was fundamental change in cultural foundation of the city which he wanted to make as world capital. 3. http://www.historyguide.org/ancient/lecture12b.html The upper panels on the short front and back walls, the location of the two doorways to the sanctuary, show four scenes from Roman history and religion. All but one are in a poor state of preservation. On the front are the fragments of two scenes from the most ancien t history of Rome: on the right Aeneas Sacrificing to Penates (4)(ancestral household gods) and on the left the god Mars with Romulus and Remus. Both scenes concern legendary founders of the Roman state. Aeneas, a hero of from Troy (celebrated in Virgil’s epic poem, the Aeneid, commissioned by Augustus), was regarded as the first settler on Italian shores. Romulus and Remus, the twin sons of Mars who were nursed by the-wolf were the founders of the city. The two ceremonial processions on the longer side

Leadership Theory and Ms. Mayme Research Paper Example | Topics and Well Written Essays - 1500 words

Leadership Theory and Ms. Mayme - Research Paper Example He is either appointed by the senior levels of management or elected by the group. However, a leader can not have all the skills required of the role. The best situation will be to have as a leader someone who is flexible but firm. When it is required, he will let the leadership act to the others. According to Kouzes and Posner (1995), leadership begins where management ends. The management system of reward and punishment will give way to the innovation, individual character and the courage of conviction of a leader. Management skills alone are not enough to create success in an organization. Leaders are needed to seek out areas to improve. They enjoy challenges and taking them head on. Leaders are motivated and expected to challenge existing paradigms. The Theory X and Theory Y were first proposed by Douglas McGregor in his 1960 book The Human Side Of Enterprise. In his theory, there are two fundamental approaches to managing people. According to McGregor, Theory X is the authoritar ian style of leadership while Theory Y is the participative style of leadership.(Hindle, 2003) Theory X assumes that the average person dislikes work and will avoid it he/she can. In business, leaders must counteract an inherent human tendency to avoid work. Therefore most people must be forced with the threat of punishment to work towards organizational objectives. The average person prefers to be directed. He chooses to avoid responsibility. He is relatively unambitious, and wants security above all else.
