Negative affect and hormone levels in young adolescents: Concurrent and predictive perspectives

The purpose of this study was to test hypotheses regarding (1) relations among negative affect and hormones of gonadal and adrenal origin in young adolescents, at three times of measurement, over a one-year period; and (2) stability of negative affect. The sample consisted of 10- to 14-year-old boys (N=56) and 9- to 14-year-old girls (N=52). The adolescents were assessed three times at 6-month intervals over one year. Serum levels of gonadotropins, gonadal steroids, adrenal androgens, and cortisol were assessed, as well as stage of pubertal development (Tanner criteria). The negative affect assessments consisted of self-report questionnaire and interview measures of anxiety and depressive affect, as well as mother reports of internalizing behavior problems. In the concurrent (cross-sectional) analyses, boys reporting higher levels of negative affect tended to be those at higher genital stage or older age, with lower testosterone and cortisol levels and lower dehydroepian-drosterone sulphate levels. In the longitudinal analyses, negative affect, and to a lesser extent hormone levels at the first time of measurement predicted negative affect 12 months later. The findings suggest that puberty-related hormone levels should be considered along with psychological characteristics in examining the processes involved in the development of negative affect during the pubertal years.Received Ph.D. from The Pennsylvania State University.

Body image satisfaction,dieting beliefs,and weight loss behaviors in adolescent girls and boys

Body image and weight loss beliefs and behaviors were assessed in 341 female and 221 male high school students. Estimates of body dissatisfaction varied depending on the measurement strategy used. Despite having similar weight distributions around the expected norm, girls were significantly more dissatisfied with their bodies than boys. Body Mass Index was positively related to body dissatisfaction in girls and boys, while higher exercise levels were related to higher body satisfaction in boys. Nearly two-thirds of girls and boys believed being thinner would have an impact on their lives, but the majority of girls believed this would be positive while the majority of boys believed this would be negative. Thirteen percent of female subjects reported using one or more extreme weight loss behavior at least weekly. Beliefs regarding the effectiveness of different weight loss measures were assessed. Weight loss behaviors in this Australian sample appear similar to comparable U.S. samples.Received Ph.D. from University of Tasmania.

Medicaid's Role in Moves Toward Universal Health Care

This paper considers the problems currently facing the Medical Assistance (Medicaid) program in light of the major problems confronting the American health care system. Actual and proposed Medicaid reforms are reviewed, their merits noted and their shortcomings detailed. It is argued that substantial Medicaid reform can take place only in the context of radical reform of the entire U.S. health care system. Similarly, Medicaid should be incorporated into any plan aimed at providing universal health care coverage.     

Variation in central bank independence across countries: Some provisional empirical evidence

In this paper seven hypotheses to explain variation in central bank independence across countries are tested. The predictions based upon the theory that delegation of authority by politicians to the central bank is used as a commitment device are not supported: central bank independence is not higher the larger the employment motivated inflationary bias, the higher political instability or the larger the government debt. Central bank independence is positively related to historical inflation experience and negatively with political instability. We do only find limited support for the view that countries with a universal banking system and countries whose central banks do not regulate financial institutions have more independent central banks.

Third party voting and the rational voter model: Empirical evidence from recent presidential elections

This paper attempted to demonstrate that a rational voter model as derived by Barzel and Silberberg (1973) can be used (with modifications) to explain third party voting in presidential elections. The empirical findings strongly suggest that the rational voter model is applicable in explaining third party voting. This conclusion likewise suggests that people who vote for third parties do so under similar motivations as people who vote for the major parties. Thus, people do not appear to regard votes for third parties as wasted votes or engage in the voting process in an irrational fashion. Lastly, votes for third parties represent the transmission of individual preferences by people who believe that their vote is important and that in the aggregate their signal may be interpreted as a signal to alter the direction of current policies as run by the major parties. Therefore, it does not appear from the evidence presented here that we should distinguish between or treat differently voting participation for the major parties versus the minor or third parties in presidential elections.The author expresses appreciation to Charles Campbell, Gary Pecquet, Paul W. Grimes, and James E. McClure for comments and criticisms. The usual caveat applies.     

POLICY AS A MOVING TARGET: A CALL FOR CONCEPTUAL REALISM

Since the early 1970s, policy scholars have paid great attention to issues of policy implementation, treating it as the "missing link" between policy formulation and results. Most often, policy problems have been seen as static phenomena that can be corrected by carefully specified programs. This paper, drawing upon examples from Swedish energy policy, argues that this is not the case, that political and social conditions are so prone to change that implementation must be a dynamic process if it is to be effective. This has distinct conceptual and practical implications for the study and design of policy implementation.
