Press and TV as Opinion Resources in Presidential Campaigns

A comparison of campaign news in two successive presidentialelections reveals major deficiencies in information supply.Newspaper audiences, even more than television viewers, receiveconfusing, heavily negative information which makes candidateappraisal difficult. Incumbency of one candidate does not leadto substantially greater emphasis on public policy issues andprofessional qualifications. A pattern of heavy stress on personalcharacteristics and daily campaign events prevails in all sources.Data come from content analysis of nearly 10,000 campaign storiesfrom network television news and 20 U.S. daily newspapers.     

Use of a case study in sequencing/scheduling research

This paper describes a study of an industrial sequencing/scheduling problem. The study contains the definition of the problem, data requirements and examination of solution technique. Definition of the problem is discussed from the aspect of uniqueness of the specific system. Discussion of data requirements includes availability and accuracy, while examination of solution technique considers limitation of time, computer capacity, etc., as well as the possibility of imbedding available algorithms into the solution procedure. Conclusions are presented relative to the use of the case study approach in sequencing/scheduling research.     

Parent – Adolescent Relationships and Girls’ Unhealthy Eating: Testing Reciprocal Effects

This longitudinal study tested the direction of associations between parent –adolescent relationships and adolescent girls’ unhealthy eating. Girls (N= 184) were seen at Time 1 (M age = 14.30 years), and then again 2 years later (Time 2; M age = 16.04 years). At both assessment periods, they completed measures that assessed their eating attitudes and behaviors, relationships with their parents, height, weight, and age of menarche. Whereas unhealthy family relationships have been hypothesized as a precursor to unhealthy eating attitudes and behaviors, it is also possible that increases in these behaviors contribute to more negative relationships within the family. Structural equation modeling was employed to simultaneously investigate the longitudinal influence of parent – adolescent relationships on girls’ unhealthy eating, and girls’ unhealthy eating on parent – adolescent relationships. The model was tested with the following controls: body mass (kg/m²), pubertal timing and age. A longitudinal direct effect was found for unhealthy eating on parent– adolescent relationships; however, no direct effect was found for parent– adolescent relationships on unhealthy eating over time. For middle– and late–adolescent girls, it appears that unhealthy eating behaviors and attitudes are predictive of less positive parent – adolescent relationships over time.     

A hierarchical theory of occupational segregation and wage discrimination

Becker's model of discrimination is extended to the case where men exhibit distastes for working under female managers. The distribution of women in the resulting occupational hierarchy depends on the number of women in lower occupations, the wages of male workers in lower occupations, and male distastes for female management. Thus, there exists an occupational sorting function, related to wages, that determines the occupational distribution of women. We integrate this sorting function into a standard wage equation to derive a new decomposition of male-female wage differentials and apply it to a sample of insurance industry workers from the 1988 CPS.     

Maternal Influences on Smoking Initiation Among Urban Adolescent Girls

This study examined associations between maternal social influences to smoke and girls' early smoking behaviors. Data were collected separately from 450 urban minority girls (65.7% Black, 21.5% Latina, and 12.8% other) and their mothers on smoking frequency as well as demographic and social factors hypothesized to promote smoking. Results showed perception of mothers' smoking to be associated with girls' early smoking behaviors, whereas mothers' report of their smoking status was not. Interactions were found between ethnicity and perception of mothers' smoking, with Black girls more influenced by their perceptions of mothers' smoking status and by mothers' expectations of adult smoking than Latinas. Findings are discussed in terms of implications for preventive efforts and recommendations for future studies with urban populations.     

Testing the equality of location parameters of exponential populations from censored samples

The modified Tiku test and the modified likelihood ratio test proposed by Tiku and Vaughan (1991) for k=2 exponential populations are extended to . k > 2 populations. These tests are shown to be more powerful than the test proposed by Kambo and Awad (1985). Unlike the Kambo-Awad test, the proposed tests are shown to have almost symmetric power functions. Further, these tests can be applied when there is both left or right censoring present, in contrast to the tests of Sukhatme (1937), Bain and Englehardt (1991) and Elewa et al. (1992), who assume that there is no left censoring.
