Social Constructionism essays

Social Constructionism essays This essay will illustrate the diversity and change within modern family structures over the past thirty years, whilst identifying ways in which these changes may have impacted upon young people and the subsequent implications for workers undertaking direct work with young people. It will demonstrate an understanding and offer examples of how social constructionism helps us interpret the meaning of the society we live in at any given time. Social constructionists argue that reality, the everyday meanings applied to our existence is constructed by social, cultural, economic, political and religious processes. These processes historically are changeable, giving different definition to society at different points in times. Therefore our attitudes, understanding and expectations of society and issues within it will be influenced by the meanings attached. Firstly there has been a marked increase in single parent families. In the UK in 1995 there were an estimated 1:4 families headed by a single parent, the majority (but by no means all) of whom are women in the 16:24 age group (Wilkinson and Mulgan 1995). Historically there have always been single parent families, but what has changed is societies attitudes, perceptions and beliefs attached to adults and children living within such units, whether through unforeseen circumstances, limited life opportunities or personal choice. In the 1950s and 60s young women who became pregnant outside of wedlock were considered loose and immoral with the child subsequently labelled a bastard. These linguistic terms are rarely used in the 90s with the younger generation being much more likely to view an upbringing in a single parent family as equally valid (ref course material). Although there has been a social shift in attitudes towards single mothers, politically the subject area continues to create much debate, Charles Murray ...

How to Measure Volume and Density

How to Measure Volume and Density Archimedes needed to determine if a goldsmith had embezzled gold during the manufacture of the royal crown for King Hiero I of Syracuse. How would you find out if a crown was made of gold or a cheaper alloy? How would you know if the crown was a base metal with a golden exterior? Gold is a very heavy metal (even heavier than lead, though lead has a higher atomic weight), so one way to test the crown would be to determine its density (mass per unit volume). Archimedes could use scales to find the mass of the crown, but how would he find the volume? Melting the crown down to cast it into a cube or sphere would make for an easy calculation and an angry king. After pondering the problem, it occurred to Archimedes that he could calculate volume based on how much water the crown displaced. Technically, he didnt even need to weigh the crown, if he had access to the royal treasury since he could just compare the displacement of water by the crown with the displacement of water by an equal volume of the gold the smith was given to use. According to the story, once Archimedes hit upon the solution to his problem, he burst outside, naked, and ran through the streets yelling, Eureka! Eureka! Some of this might be fiction, but Archimedes idea to calculate the volume of an object and its density  if you know the objects weight was fact. For a small object, in the lab, the easiest way to do this is to partly fill a graduated cylinder large enough to contain the object with water (or some liquid in which the object wont dissolve). Record the volume of water. Add the object, being careful to eliminate air bubbles. Record the new volume. The volume of the object is the initial volume in the cylinder subtracted from the final volume. If you have the objects mass, its density is the mass divided by its volume. How to Do It at Home Most people dont keep graduated cylinders in their homes. The closest thing to it would be a liquid measuring cup, which will accomplish the same task, but with a lot less accuracy. There is another way to calculate volume using Archimedes displacement method. Partially fill a box or cylindrical container with liquid.Mark the initial liquid level on the outside of the container with a marker.Add the object.Mark the new liquid level.Measure the distance between the original and final liquid levels. If the container was rectangular or square, the volume of the object is the inside width of the container multiplied by the inside length of the container (both numbers are the same in a cube), multiplied by the distance the liquid was displaced (length x width x height volume). For a cylinder, measure the diameter of the circle inside the container. The radius of the cylinder is 1/2 the diameter. The volume of your object is pi (Ï€, ~3.14) multiplied by the square of the radius multiplied by the difference in liquid levels (Ï€r2h).
