The phenomena of Colony Collapse Disorder in honeybee Essay

The Phenomena Of Colony Collapse Disorder In Honeybee Populations - Essay Example The symptoms include, among others, the presence of younger honeybees, around the healthy queen bee as the older and adult honeybees leave the hive, without coming back to it. In addition, studies have shown that the apparently visible symptom could be the absence of wax moths, or small hive beetles or other hive pests that could invade the beehives. The causes of CCD could include different virus causing diseases like American and European foulbrood, Nosema and other disease-causing pathogens, as their presence is alarming to the honeybee population. In addition, the invasive pest species also causes CCD. However, a combination of various pathogens would be responsible for CCD, rather than an isolated virus. The other major factors responsible for the large disappearance of Honeybee populations are chemicals that would be present in the beehive and the environment, while honeybee growing into a monocropping  agricultural system can also be a cause for CCD as proper nutrition is not allowed for the honey bee, to grow naturally. While these factors and other causes of CCD are described below, it is important to mention here that scientists are still trying to isolate any pertinent causes, including the use of chemicals and behavior of honeybees, responsible for CCD that has resulted in national worry as agriculture produce is getting severely affected due to this phenomenon.....(University of Arkansas, 2009) Earlier known as Fall Dwindle Disease, CCD is the dying process of healthy honeybees colonies, which makes them disappear, within a very short span of time, just around three weeks. The apparent indications are that the workforce of such colonies comprises mainly young bees and they are reluctant to consume the provided feed. After this collapse, no adult bees are left, while no invasion takes place to rob the colony of its food that still remains there.

Bodega Dreams by Quinonez, Ernesto Research Paper

Bodega Dreams by Quinonez, Ernesto - Research Paper Example In order to understand light, we compare it to darkness; in order to understand man, we come compare it to woman; and in order to understand reason, we compare it nature. However, these binaries are not equal, in that one side of the binary is posited as good, rational, civilized, and empowered, and the other side of the binary is posited as bad, irrational, uncivilized, and subordinate. This process of dividing everything into categories of good and bad is important when attempting to understand the dynamics of power in social relationships, especially ones that are characterized by race, class, and gender. The codification of binaries has acted as a catalyst for the process of othering, which explains how certain groups remain in possession of power while other groups are continuous enslaved by social, political, and educational institutions that benefit from their oppression. Lena Dominelli defines othering as following: Thus, racism is about relations of dominance and subordination which are rooted in the ‘othering’of others as a social process of exclusion in which particular personal attributes are identified as the basis for a racialised ‘othering’ to occur. These characteristics are aspects of an individual’s or group’s identity which are castigated as ‘inferior’ by a dominant group which has the power to enforce its definitions of reality on others. They may be based on biological features such as skin color and hair type, cultural practices, linguistic abilities, or religious observances which are adversely valued socially and weighted against the interests of the subordinated group. (39). This assumption of the superiority of one race to dominate, manipulate, and abuse other groups who are perceived as inferior has colored much of American history (Lorde, 115). However, regardless of how hard the other tries
