Television viewing and adolescents' sexual behavior.

Over the past two decades the sexual content on television has increased in frequency and explicitness but has seldom included depiction of the use of contraceptives. Concurrently, the age of initiation of heterosexual intercourse has decreased and the number of teenaged pregnancies has remained high. Are these trends related? This survey of 391 adolescents found that those who chose heavier diets of sexy television shows were more likely than those who viewed a smaller proportion of sexual content on television to have had sexual intercourse. This relationship held regardless of perceived peer encouragement to engage in sex and across race and gender groups. While causal direction is not clear from these data, the relationship suggests that either sexual activity results in increased interest in sexual content in the media and/or that viewing such content leads to sexual activity. In either case, the finding points to the need for further research and increased discussion and portrayal of the use of contraceptives on television.     

Life-threatening disability in adolescence: Adjusting to a limited future

This paper describes a medical social worker's efforts over one and a half years to help a client adjust to a neurological disorder. Prior to social work services, the young woman had never discussed her disability, which began in adolescence, with anyone outside the family, and communication within the family was seriously compromised by their perception of disability as a stigma. Lacking the opportunity to mourn the loss of her physical abilities, she became isolated and depressed, and acted out aggressive thoughts and fantasies within the family system. Social work intervention helped the client to re-work the original trauma of diagnosis, which led to the development of a healthier defensive structure and new coping mechanisms.     

Emotional displays in children's television programming

The facial expressions of emotion and the circumstances under which the expressions occurred in a sample of the most popular children's television programs were investigated in this study. Fifteen-second randomly selected intervals from episodes of five television programs were analyzed for displays of happiness, sadness, anger, fear, disgust, and surprise. In addition, the contexts in which the emotions occurred were examined. Results indicated that particular emotional expressions occurred at significantly different frequencies and that there was an association between emotional displays and emotion-contexts. The high rate of emotional displays found in television shows has implications for the development of knowledge regarding emotional display rules in viewers.We are grateful to Sharon Galligan for assistance in coding part of the data and to Carolyn Saarni and Amy Halberstadt for helpful comments on an earlier draft of this paper.

DEALING WITH ARGUABLY LEGITIMATE EXAM GRIPES: A POSSIBLE PARETO IMPROVEMENT

Students sometimes have heart-felt and arguably legitimate complaints about exam grading. This note suggests a strategy for dealing in a serious, judicious and seemingly fair and responsive way with such complaints. The suggested strategy allows the professor to take such complaints seriously, without giving him/her the reputation as an easy mark. Moreover, it uses a characteristic of letter-grade systems to lower the transactions costs of dealing seriously with such complaints.     

Arrow's paradox and mathematical theory of democracy

Two measures, the weight of coalitions and the probability of situations in decision making, are used to characterize the representativeness, i.e. the capability of individuals to represent the social preference. It is proved that there always exists an individual who represents a majority on average, and an individual who represents a majority in most cases. This result is applied to Arrow's social choice model. It follows that there always exists a dictator who is a representative of the society rather than a dictator in a proper sense. After the concept of dictator has been refined to a dictator in a proper sense, Arrow's axioms become consistent. The idea of optimal representation is extended to limited groups of representatives which make decisions on behalf of the whole society. We consider the cabinet (named by analogy with the cabinet of ministers) which consists of a few representatives with delimited domains of competence, and the council which makes decisions by means of voting. It is shown that the representativeness of optimal cabinets and councils tends to 100% of maximally possible values as the number of their members increases, independently of the size of the society. We suggest a geometric interpretation of optimal representatives, cabinets, and councils, based on approximation formulas for the indicators of representativeness derived for the model with a large number of independent individuals. Finally, for cabinets and councils we establish the consistency of different concepts of optimality with respect to different indicators of representativeness. Our consideration is applicable to multicriteria decision making. An appointment of a cabinet or a council corresponds to selecting a few partial criteria. Therefore, the obtained results can be used for reducing the set of partial criteria to a certain sufficient minimum. The concepts of dictator, cabinet, and council can be understood as models of president, government, and parliament, respectively. Thus our results justify reducing social choice to individual choice or small group choice. Although it is in use in all democratic systems, its acceptability is not evident at all. In other words, we justify the demoncraticity of such forms of political power as the president, the parliament, and the government.     

Maximization of reinforcement by two autistic students with accurate and inaccurate instructions

The present study examines maximization of reinforcement by two autistic individuals under conditions of no instructions, accurate instructions, and inaccurate instructions. Accuracy of instructions and magnitude of reinforcement for differential responding in a choice paradigm were systematically varied across phases. Subject one maximized reinforcement across all three conditions in seven experimental phases. Subject two maximized across these same seven phases, but also experienced three additional phases. In two of the additional phases, subject two maximized reinforcement. In a ninth phase, when reinforcement was intermittent rather than continuous, he failed to maximize reinforcement. Implications of the results for the controversies surrounding the concept of rule-governed behavior are discussed.

     

Treatment of psychogenic seizures in adolescents

This article will review the problem of psychogenic seizures in adolescents and the impact of family therapy and individual therapy on treatment. Why particular individuals are prone to psychogenic seizures, the relationship between psychogenic seizures and family dynamics, and unresolved individual issues will be covered. The article will address a selected case, with a specific clinical paradigm for treatment.
