Vocal determinants of first impressions of young children

Audiotapes of the voices of77 preschool children were prepared. Subjects listened to the tapes, and then provided their impressions of the competence, leadership, dominance, warmth, and honesty of the children. Judgments of the voices' babyishness and attractiveness were also obtained. Perceivers reliably discriminated the children's voices along the dimensions of babyishness and attractiveness. Moreover, analyses revealed that the previously documented impact of these characteristics on first impressions of adults extends to impressions of young children. The similarity of the effects of these characteristics on impressions formed about children to those revealed for adults suggests that vocal qualities may have an impact on personality development via a process of self-fulfilling prophecy.     

Clinical social work and the family court: A new role in child sexual abuse cases

Clinical social workers encounter difficult treatment issues when working with children where there is a suspicion of child sexual abuse, or where there has been an indicated child protective services case but no family court action. This article outlines a new role for the clinical social worker to play in relationship to the family court system. The author argues that the involvement of the clinician in an assessment process developed to aid the court can aid in the protection of children and set the stage for effective intervention and treatment.Director, Center for Training and Research in Child Abuse and Family Violence.     

Measures of Compounding Conservatism in Probabilistic Risk Assessment

Concern about the degree of uncertainty and potential conservatism in deterministic point estimates of risk has prompted researchers to turn increasingly to probabilistic methods for risk assessment. With Monte Carlo simulation techniques, distributions of risk reflecting uncertainty and/or variability are generated as an alternative. In this paper the compounding of conservatism⁽¹⁾ between the level associated with point estimate inputs selected from probability distributions and the level associated with the deterministic value of risk calculated using these inputs is explored. Two measures of compounded conservatism are compared and contrasted. The first measure considered, F , is defined as the ratio of the risk value, R _d, calculated deterministically as a function of n inputs each at the j th percentile of its probability distribution, and the risk value, R _j that falls at the j th percentile of the simulated risk distribution (i.e., F=R_d/R_j). The percentile of the simulated risk distribution which corresponds to the deterministic value, R_d , serves as a second measure of compounded conservatism. Analytical results for simple products of lognormal distributions are presented. In addition, a numerical treatment of several complex cases is presented using five simulation analyses from the literature to illustrate. Overall, there are cases in which conservatism compounds dramatically for deterministic point estimates of risk constructed from upper percentiles of input parameters, as well as those for which the effect is less notable. The analytical and numerical techniques discussed are intended to help analysts explore the factors that influence the magnitude of compounding conservatism in specific cases.     

Mental load and work stress as two types of energy mobilization

A conceptual framework is presented in which mental load and stress are regarded as two distinct biobehavioural states in the work environment that differ in energy mobilization, mood and coping strategy. The framework combines two types of theory that are based on human performance research using laboratory tasks on the one hand and applied research in the work environment on the other. A high workload is regarded as an important but not a critical factor in the development of stress symptoms. Even under unfavourable conditions it is possible to work intensively and to be highly activated without feelings of strain or psychosomatic complaints. In contrast, working conditions that provide few possibilities for control and little social support or are associated with reduced well-being and increased health risks. The two states differ in activation, coping style and mood. A proper distinction is important not only for theory building but also for the reconstruction of the work environment. It may lead to recommendations that aim to enhance the work efficiency of employees while reducing the probability that stress responses will occur.     

Environmental assessment in forestry: the initial experience

This study analyses the effectiveness of the European Community's Environmental Assessment Directive of 1985 in its application in the U.K. forestry sector. It assesses the applicability of the regulations in the provision of the public and private outputs of forestry. The environmental assessment regulation may contribute to the provision of the optimal amount of these public and private goods in theory, but it is concluded that, in common with initial results of the environmental assessment process in other sectors, the regulations do not make this contribution in practice in the forestry sector. The main deficiencies of the environmental statements examined were the failure to identify the significant potential impacts; to present alternative project sites and design features; and the erroneous measure of particular externalities. The environmental assessment process was also found to be unsatisfactory in the lack of public accessibility and consultation. The need for revision of the process in the forestry sector is highlighted.     

The choice between a married or unmarried first union by young adults

In this paper the choice between marriage and unmarried cohabitation as a first union by young adults is studied. A hazard analysis is performed on a sample of 590 26-year-old men and women from the Netherlands. Students are much less likely to start a union in general, and marriage in particular, than are other categories of young adults. Young adults living at home are less likely to enter a consensual union than those living on their own. Religious young adults are much less likely to enter a consensual union and much more likely to marry than are non-religious ones. Educational attainments at age 16 do not influence union formation.Cet article étudie le choix des jeunes adultes entre mariage et cohabitation pour leur première union : une analyse, utilisant un modèle à risques proportionnels, est effectuée sur un échantillon de 590 jeunes hommes et jeunes femmes âgés de 26 ans en Hollande. Les étudiants ont une plus faible probabilité de s'engager dans une union en général, et plus particulièrement dans un mariage, que les autres catégories de jeunes. Les jeunes vivant chez leurs parents ont également une plus faible probabilité d'entrer dans une union consensuelle que ceux vivant indépendamment. Enfin les jeunes qui pratiquent une religion ont une plus faible probabilité d'entrer dans une union consensuelle et une plus forte probabilité de se marier que les non pratiquants. En revanche le niveau d'éducation à 16 ans n'a aucune influence sur les unions à venir.

ASYMPTOTIC EXPANSIONS APPLIED TO F-TEST CRITERIA

Using asymptotic expansions of the Kummer hypergeometric function, the sequential. F-test criterion is evaluated asymptotically in terms of the sample size. The continuation region inequalities for the test are inverted and expressed in terms of known test criteria. A rapidly converging algorithm for carrying out the sequential procedure is provided. This makes the F-test easier for the practitioner to use. Almost sure finite termination of the sequential. F-test is asserted by appealing to the continuation inequalities and a heuristic asymptotic expansion of the test criterion. Average stopping times of the sequential procedure for a variety of population means and population number configurations are tabulated. The computer symbolic manipulation program MAPLE was used to derive some formulae.     

Criteria families use to select nursing homes

The study is conducted to determine families' rankings of characteristics they consider most important when selecting a nursing home. Friedman's two-way analysis of variance is used to test for differences in the rankings. In response to a mailed survey, 231 families rank the characteristics in the following order: quality of care, appearance, atmosphere, location, reputation, building safety, quality of food, cost, and activities. Relationships are also found between the rankings and the demographic characteristics: gender, marital status, education, income, number of homes available, patient/respondent relationship, and distance respondent lived from the chosen home.
