Prime Rational Functions and Integral Polynomials

Let f(x) be a complex rational function. In this work, we study conditions under which f(x) cannot be written as the composition of two rational functions which are not units under the operation of function composition. In this case, we say that f(x) is prime. We give sufficient conditions for complex rational functions to be prime in terms of their degrees and their critical values, and we derive some conditions for the case of complex polynomials. We consider also the divisibility of integral polynomials, and we present a generalization of a theorem of Nieto. We show that if f(x) and g(x) are integral polynomials such that the content of g divides the content of f and g(n) divides f(n) for an integer n whose absolute value is larger than a certain bound, then g(x) divides f(x) in Z[x]. In addition, given an integral polynomial f(x), we provide a method to determine if f is irreducible over Z, and if not, find one of its divisors in Z[x].

Examining Bullying Intervention Motivations Through a Cost/Benefit Analysis

The purpose of the present study was to examine the role of the bystander in bullying situations. A cost/benefit model was explored in researching factors adolescents consider in deciding whether to intervene when witnessing bullying. Adolescents in the present study (N = 101 (50.5% female), between the ages of 12 to 18, M = 15.37 years; SD = 1.71 years) completed self-report questionnaires, and also responded to bullying scenarios, stating how the bystander would react, while explaining potential personal costs and benefits. Adolescents were able to articulate various personal costs and benefits when making the decision to intervene. Conclusions of the present study include: 1) the evolutionary approach is quite informative in illuminating the decision process of the bystander, 2) adolescents’ beliefs about bullying and the role of bystanders are different from their teachers’, and 3) the rather explicit cost/benefit model could be used to develop more targeted anti-bullying programs.
