The advantages and disadvantages of BACI design and its approaches Essay

The advantages and disadvantages of BACI design and its approaches - Essay Example 2009).The BACI design requires data from two sites namely the control site and the impact site. The sites are viewed as pairs and forming a block of time. The required data is collected a number of times before the impact begins as well as after. According to Anderson, et al. (2009), there are two treatments namely â€Å"Before-After† and â€Å"Control-Impact†. The first treatment is of primary interest during the second of secondary interest to the researcher. If there is an environmental disturbance that affects the given population, academics argue that the different interactions are prevailing in the statistical mean rest responsible for the abundance results seen in the sampled population. It is arguable that the differences impose control and potentially affected location before the disturbance and that difference after the disturbance (Lucas et al. 2013). The final problem is that there are certain environmental disturbances that cannot be detected by using the BACI design; these disturbances alter the temporal pattern of variance of abundance when statistical calculations are involved (Lucas et al. 2013). 2. Behavioral element developed by the birds such as avoiding the vicinity of the turbines. This can have an effect on the birds such as displacing them from their natural habitats and affecting their movement patterns This is a design made to analyze changes in means because of human activity. The simplest form involves collecting data on the activity and comparing it with the data from the event. The standard approach is to treat data as independent samples and to compare the samples using the two-sample test. Any differences found in the samples are associated with the given activity. However, it is difficult to make a causal inference as the data collected is observational and depends on several assumptions (Langston, Pullan & Council of Europe, 2010).The Disadvantages of this design is that

Intoduce two organizations from United Nations Essay

Intoduce two organizations from United Nations - Essay Example The United Nation’s General Assembly is the main organization within the UN. The General Assembly is the primary organization for deliberation. This organization contains all of the nations that are a part of the United Nations. In terms of how frequently this organization meets, it’s noted that regular yearly sessions occur. Regarding hierarchy, â€Å"the organization elects a yearly president that oversees the presiding meetings† (Fasulo, p. 21). The annual meeting occurs over a two-week period. During this time all organizations are given an opportunity to address the assembly. The formal proceedings of this assembly feature an opening statement by the Secretary-General. This statement is followed by a statement from the president of the assembly. After lengthy debate and presentations occur the General Assembly will oftentimes vote on important issues. In terms of the voting structure, it’s necessary for two-thirds of the organization to vote and agree on an issue before it is enacted. There are a great amount of potential issues that could be considered at the General Assembly convention. Many of the predominant issues are human rights concerns. Another prominent United Nation’s organization is the Security Council. This organization’s primary responsibility is the establishment and maintenance of peace and security among countries. While the General Assembly has the power to pass security concerns, the Security Council is recognized as being the only organization that can pass biding regulations regard security concerns. While the General Assembly is composed of all nations that are members of the United Nations, the Security Council is restricted to certain nations. In these regards, â€Å"15 members are on the Security Council board, with five permanent members and ten non-permanent members† (Mesler, pg. 111). There are a number of elements related to this structure
