Aspects Of A Negro Life Through his political activism and his artwork, Douglas dramatically changed the way other artists viewed African Americans. Politically, he helped found and served as president for the activist organization that drastically assisted with employing thousands of artists. he 1920s and 1930s brought drastic changes to the lives of many African Americans. Geographically, they migrated toward the urban, industrialized North, not only to escape racial prejudices and economic hardships, but also to attain higher social and economic status. This Ã¢â¬Å"Great MigrationÃ¢â¬ transformed the streets of Harlem, New York, and gave rise to cultural changes of the New Negro movement. As this movement gradually gained popularity,Ã¢â¬ ¦show more contentÃ¢â¬ ¦Through his political activism and artwork, Douglas was able to reveal the ideas and values exemplified during the Harlem Renaissance, despite significant criticism of his style. With this rebirth of traditional African culture, the number of African American artists rapidly increased. It became difficult for these artists to gain employment, even with the assistance of government work-relief programs, such as the Works Progress Administration (WPA). Set up by President Roosevelt as part of his New Deal program, the WPA offered jobs to thousands of unemployed artists, in an attempt to boost the nationÃ¢â¬â¢s morale, as well as stimulate the depressed economy. Despite its good intentions, the government program was unable to pay decent wages and failed to provide employment for nearly five million artists (American). In response to this failure, the Harlem Artist Guild, founded in 1928, aggressively began to work alongside the WPA to ensure the success of African American artists. Led by its first president, Aaron Douglas, the activist organization played an influential role in helping artists attain the recognition necessary to qualify them for the WPA work projects (Bearden 131). With the assistance of Douglas, the Harlem Artist Guild, and the WPA, millions of African American artists succeeded in gaining employment despite the hard times of the 1930s (ArtnoirÃ¢â¬â¢s).

Definition of key Terminology/Background The explosion of technology on the education scene in the past few decades has been enormous. Toward the end of 20th century, one of the most frequent suggestions educational leaders made for improving schools was the integration of technology into teaching and learning processes (Henson, 2010, p.63). Mercelle (2000) defined ICT as Ã¢â¬Å"complex and heterogeneous set of good applications and services used for producing, distributing, processing and transforming information-including telecoms, TV and radio broadcasting, computer hardware and software, computer services and electronic media (e.g. Internet, electronic mail, electronic commerce etc.)Ã¢â¬ . Voogt (2003) explained that ICT is not regarded as a tool which can be added to or used as a substitute of existing teaching method, but it is regarded as an important instrument to support teaching and learning. Henson (2010) added further that Ã¢â¬Å"although substantial progress has been made, the integration is still far from complete, even at the college levelÃ¢â¬ (p.63). Investment in ICT to improve teaching and learning in schools have been initiated by many countries. Nut (2010) mentioned that in the United Kingdom for instance, a research by the British Education SuppliersÃ¢â¬â¢ Association (BESA) reported that in 2009-10, UK state schools recorded ICT budget of Ã £576.8 million.

IÃ¢â¬â¢m not really sure if I am interpreting this right but to me, the Ã¢â¬Å"waltzÃ¢â¬ shows me the difference between what the soldier is wearing and who he is. 9. I think that a comparison connects both war and violence with intimacy/courtship by showing that love can be hard and violent, and that intimacy/relationships can cause great damage. 10. The picture is missing from the book. I think this serves as a way to point out that we donÃ¢â¬â¢t think of the people who die as real people unless we are connected to them.

Ships needed to transport prove of where the sugar came from. The Stamp Act truly pissed the settler off. It was the first internal revenue enhancement directed right at the settler. This revenue enhancement meant that any paperss of importance such as newspapers, playing cards, and legal paperss needed to hold a cast on them, of class this cost the settler money. The settler where really angry, the believed they had helped the British in the Gallic and Indian war, and this was unjust. They revolted in many ways, one being people where pitch and feathered. The Townshend Duties Act was another manner of acquiring more for their money out of the settler. Because they didn?

Archaeopteris - The First Modern Tree on Earth Our earths first modern tree establishing itself in developing forests emerged around 370 million years ago. Ancient plants made it out of water 130 million years earlier but none were considered true trees. True tree growth only came about when plants overcame biomechanical problems to support additional weight. The architecture of the modern tree is defined by evolutionary features of strength that builds in rings to support greater and greater height and weight, of protective bark that shields the cells that conduct water and nutrients from the earth to the furthest leaves, of supportive collars of extra wood that surround the bases of each branch, and of internal layers of wood dovetail at branch junctions to prevent breakage. It took over a hundred million years for this to happen. Archaeopteris, an extinct tree that made up most of the forests across the earths surface in the late Devonian period, is considered by scientists to be the first modern tree. New collected pieces of fossils of the trees wood from Morocco have filled in parts of the puzzle to shed new light. Discovery of Archaeopteris Stephen Scheckler, a professor of biology and geological sciences at Virginia Polytechnic Institute, Brigitte Meyer-Berthaud, of the Institut de lEvolution of Montpellier, France, and Jobst Wendt, of the Geological and Paleontological Institute in Germany, analyzed a trove of these African fossils. They now propose Archaeopteris to be the earliest known modern tree, with buds, reinforced branch joints, and branched trunks similar to todays modern tree. When it appeared, it very quickly became the dominant tree all over the Earth, says Scheckler. On all of the land areas that were habitable, they had this tree. Scheckler goes on to point out, The attachment of branches was the same as modern trees, with swelling at the branch base to form a strengthening collar and with internal layers of wood dovetailed to resist breaking. We had always thought this was modern, but it turns out that the first woody trees on earth had the same design. While other trees quickly met extinction, Archaeopteris made up 90 percent of the forests and stayed around a very long time. With trunks up to three feet wide, the trees grew perhaps 60 to 90 feet tall. Unlike present-day trees, Archaeopteris reproduced by shedding spores instead of seeds. Development of the Modern Ecosystem Archaeopteris stretched out its branches and canopy of leaves to nourish life in the streams. The decaying trunks and leaves and the altered carbon dioxide/oxygen atmosphere abruptly changed ecosystems all over the earth. Its litter fed the streams and was a major factor in the evolution of freshwater fishes, whose numbers and varieties exploded in that time, and influenced the evolution of other marine ecosystems, says Scheckler. It was the first plant to produce an extensive root system, so had a profound impact on soil chemistry. And once these ecosystem changes happened, they were changed for all time.Ã Archaeopteris made the world almost a modern world in terms of ecosystems that surround us now, Scheckler concludes.

Sociology Research Method essays Sociology is the scientific study of human social behavior. As the study of humans in their collective aspect, sociology is concerned with all group activities: economic, social, political, and religious. Sociologists are the researchers of sociology. Sociologist study such areas as bureaucracy, community, deviant behavior, family, public opinion, social change, social mobility, social stratification, and such specific problems as crime, divorce, child abuse, and substance addiction. Sociology tries to determine the laws governing human behavior in social contexts. Sociology focuses on how groups affect the individual. There are many factors that play a role in sociology such as , ethnic background , gender and peers. I find the ways we research and study sociology to be very interesting. I will explain how it is done by sociologists. The ways sociology is researched is by the scientific research method.

The steps to the scientific method are as follows. First, of all you are going to want to find to what question of sociology you would like to find the answer. This first step is called defining the problem. When defining the problem, you decide what the purpose of the study is. At this stage in the research you are also trying to figure out what information is needed and how it will be used. Next, you are going to want to review previous research. In this step you will find out what studies have been done on this topic, and what additional information you will be need to gather. After the research is done your going to want to state a hypothesis as to the outcome of the experiment. Technically speaking, the hypothesis is a statement that predicts a relationship betw ...

Chemistry of hazardous materials - Essay Example Thus, not only gloves but also other equipments along with protective measures are also necessary while handling phosphorus (Lenntech, 1998). Phosphorus slowly reacts with water and forms phosphine. It should be noted that Phosphine is a poisonous gas that is released when solids like phosphorus are exposed to water. Therefore, phosphorus becomes a water reactant. When this poisonous gas is exposed to water, it can contribute to the danger to the firefighters because the basic element that they use while extinguishing a fire is water. Thus, water can release oxygen from the water-reactive materials and can add to the fire causing the fire to aggravate rather extinguish. In order, to reduce the fire and finally extinguish it, it is necessary to use dry sand rather water to reduce the risk of aggravation of fire. Thus, it is advisable to the fire fighters to use dry sand while extinguishing the fire that is ignited due to red phosphorus (Burke,
