Ecological validity

The Barangaroo development brought up different aspects in relation to sustainability, social Justice and Equity. They affect the development in both positive and negative ways. Ecological sustainability means a capacity of ecosystems to preserve their vital purposes and processes, and retain their biodiversity in the full measure over the long-term and keep them going for next generation. Social Justice can be defined as the distribution of advantages and disadvantages within a society.…

There are two different groups of participants in the study who were chosen for the study arbitrarily. The goal of the study was to find the best way to help students learn better. The researcher chose to use quizzes that were given on a weekly basis. Since the quizzes are only a very small part of the students ' final grade, it is more logical to conclude that the investigator would use the exams that were given to the students as a better measure of student learning than their marks on the…

Five Research Articles on Biodiversity Succession in Ecology: Summaries Article 1: “Effects of nitrogen deposition on soil and vegetation in primary succession stages in inland drift sands” What kind of system was being considered? -They studied the Inland drift sands in the areas of the Netherlands. They specifically looked and studied at the Drethe, Veluwe, Utrecht, Brabant, and along Meuse. They wanted to consider how plants grow and develop during succession. The author’s hypothesis: -The…

The environmentalist Bill McKibben in his book “Deep Economy” he addresses some of the major issues we have as a society and mentions some of the ways we could reach a more sustainable nation. According to him we suffer from three major crisis. The first problem, he thinks we need to deal with is politics, now days we are focusing more in the economy and forgetting about the impact it is creating in our natural environment. The second problem is growth, which refers to the idea that we have…

1. Energy flows through an environment. What are two main sources of food? Why do organisms depend on food? Who or what is the primary producer in a food web? What do the arrows tell us about a food web? How would a food web change if an organism were removed? How can energy move through an environment? 2. Organisms and events cause environmental changes. How would an environment be affected by a change that harmed some hunted organisms but favored other hunted organisms? What are some…

Reducing the environmental impact of humans has steadily become a greater issue for governments and citizens alike. We have recently become more aware of climate change through different documentaries and scientist reports. Our environmental impact does not only affect our climate, it affects our biodiversity and even the air we breathe. As our population has grown exponential over the past century, so has our environmental impact. Quite recently a greater number of influential people and…

I agree with Moss (2010), who states “the educator needs to appreciate the range of disciplines, theories and practices available, and to understand her or his responsibility to decide where to situate herself or himself in this complex and diverse range of possibilities” (Moss, 2010, p. 15). Within education there are diverse disciplines, theories and practices, and like Moss, I believe its imperative for educators to have knowledge and an understanding of these before they are able to make…

Succession is the process by which the structure of a community evolves over time. There are many factors that can affect succession, such as environmental changes, which are natural and harmless to the nature, and human-caused changes which mostly will end up ruining a succession. The two driving forces for succession include evolution and natural selection. Evolution is known as a change in the population or community that can be measured such as number of the members of the community. Natural…

The article “Dismembered human feet keep washing up on beaches in western Canada” started off with a video clip. In the video, a woman was stated her concern on the statement that was made about the foot that had washed ashore, the statement of “there is nothing to see here”. Continuing the conversation, the men stated that this foot was the 14th foot that had been washed ashore around the beach of the Salish Sea in the last century; and one of the only connections between all 14 of the foots is…

and whether or not “inappropriate elements are included in the indicator.” Although content validation is an “important contribution” to measurement validity, its chief limitation is that “alone it is incomplete, for two reasons”: “first, although a necessary condition, the findings of content validation are not a sufficient for establishing validity” and second “the trade-off between parsimony and completeness that arises because indicators routinely fail to capture the full content of a…
