The Stringency Of Environmental Regulations And Technological Change: A Specific Test Of The Porter Hypothesis

The Interaction between Involvement Load Hypothesis Evaluation Criterion and Language Proficiency: A Case in Vocabulary Retention

A long-standing debate among the vocabulary researchers is the depth of processing to learn vocabulary. This paper is a quantitative research which considers a revision in the “involvement load hypothesis” proposed by Laufer and Hulstijn in 2001. It investigates the role of proficiency and evaluation in this hypothesis in order to better reveal its potential contribution to vocabulary learning....

Testing the Convergence Clubs Hypothesis among MENA Countries

T his paper is to study the convergence of per capita income. Convergence clubs hypothesis is one of the forms of convergence hypotheses, implying that countries with the same initial level of economic development, technology, and government policies, tend to be similar in per capita income and thus have a tendency to cluster around a small number of poles. In order to test the hypot...

The Strong Story Hypothesis and the Directed Perception Hypothesis

I ask why humans are smarter than other primates, and I hypothesize that an important part of the answer lies in what I call the Strong Story Hypothesis, which holds that story telling and understanding have a central role in human intelligence. Next, I introduce another hypothesis, the Directed Perception Hypothesis, which holds that we derive much of our commonsense, including the commonsense...

HYPOTHESIS TESTING FOR AN EXCHANGEABLE NORMAL DISTRIBUTION

Consider an exchangeable normal vector with parameters ????2, and ?. On the basis of a vector observation some tests about these parameters are found and their properties are discussed. A simulation study for these tests and a few nonparametric tests are presented. Some advantages and disadvantages of these tests are discussed and a few applications are given.
