Diversity-Based Reasoning in Children

One of the hallmarks of inductive reasoning by adults is the diversity effect, namely that people draw stronger inferences from a diverse set of evidence than from a more homogenous set of evidence. However, past developmental work has not found consistent diversity effects with children age 9 and younger. We report robust sensitivity to diversity in children as young as 5, using everyday stimuli such as pictures of objects with people. Experiment 1 showed the basic diversity effect in 5- to 9-year-olds. Experiment 2 showed that, like adults, children restrict their use of diversity information when making inferences about remote categories. Experiment 3 used other stimulus sets to overcome an alternate explanation in terms of sample size rather than diversity effects. Finally, Experiment 4 showed that children more readily draw on diversity when reasoning about objects and their relations with people than when reasoning about objects' internal, hidden properties, thus partially explaining the negative findings of previous work. Relations to cross-cultural work and models of induction are discussed.     

Herbert Blumer's critique of The Polish Peasant: A post mortem on the life history approach in sociology

Herbert Blumer's appraisal of William Thomas and Florian Znaniecki's Polish Peasant study and the panel discussion of Blumer's critique, sponsored by the Social Science Research Council in 1938, occasioned a discussion of the value of personal documents in social research which is indicative of the controversy surrounding their use in the interwar period. It is suggested that most sociologists writing in the 1930s were skeptical of the value of personal document research, because such research could not be conducted along the lines of experimental procedure in physical science. Personal document research was in decline by 1938. The critique and conference constituted a post mortem examination of this approach to social analysis.     

Outcome additivity, elemental processing and blocking in human causality judgements

Informing participants in a causal judgement task that outcomes are additive can increase blocking effects (Experiment 1). Outcome additivity information emphasizes the fact that the outcome following a compound is the sum of the effects of its elements. We suggest that the effect of providing outcome additivity information is to encourage elemental processing and thereby enhance blocking. Experiment 2 showed that blocking could be enhanced by factors encouraging elemental processing, and Experiment 3 demonstrated that blocking was reduced by manipulating the visual presentation of cues to encourage configural processing. While these experiments do not rule out the role of inference in causal judgement tasks, the results are most parsimoniously explained by associative accounts that allow flexibility in the encoding of compound cues.     

The effects of perceived pressures on managerial and nonmanagerial scientists and engineers

The two major purposes of the present study were (1) to empirically investigate the effects of excessive pressures perceived by Ph.D.-level scientists and engineers employed in a large multidivisional energy R&D laboratory on work attitudes and performance; and (2) to test the proposition that scientists with managerial responsibilities perceive more pressures and strains than do those with no such duties. Results indicated that the pressured scientists perceived more role strain and a less positive climate, were less satisfied, and received lower performance evaluations from their supervisors than non-pressured ones. No differences were found in the perception of pressures between the managerial and nonmanagerial scientists, although the managers reported a more positive climate and higher satisfaction than did nonmanagers. The implications of these findings with regard to management practice (i.e., dual ladders) and future research on stress among this occupational group were briefly discussed.     

The effects of choice-making on the problem behaviors of high school students with intellectual disabilities

This investigation was conducted in an effort to systematically extend the emerging data base having to do with choice-making opportunities and the behavior of students with disabilities. In particular, the current analyses examined the effects of choice-making on the problem behavior and task engagement of three high school students with intellectual disabilities as the students performed domestic and vocational activities. Multiple baseline and reversal designs demonstrated that the choice conditions reduced problem behaviors and increased task engagement for all participants. Data having to do with student affect and task productivity were less consistent. The findings on the relationship between choice making and problem behavior replicate and extend a growing literature on the desirable effects of choice-making for individuals with disabilities. The results are discussed in terms of recent developments in behavioral support, as well as the need for ongoing conceptual and applied research.     

Families and therapists achieve clinical outcomes,systems of care mediate the process

Conclusion The values articulated in the system of care philosophy (Stroul & Friedman, 1994) have been necessary elements of local, state, and national efforts to reform mental health care for children. The importance of the values of family collaboration, cultural competence, interagency coordination, individualized care, and use of the least restrictive treatment setting articulated by the system of care philosophy has been affirmed by practitioners, policy makers, and mental health services researchers. Such values, however, are likely not sufficient to achieve clinical outcome. Clinical outcomes are more likely to be achieved by family members and therapists when clinical practices are changed to reflect the demanding and comprehensive work of changing child and family social ecologies.     

International federation for information processing’s framework for computer ethics

This paper reviews codes of ethics and codes of conduct from different countries. The differences and similarities between code content and between attitudes are considered. Distinction is drawn between a code of ethics and a code of conduct. Recommendations are made for establishing a common framework for IFIP (International Federation for Information Process) Member or Affiliate Societies.     

A call for a statement of expectations for the global information infrastructure

This paper considers the relationship between ethics, technology and law, and the roles and limitations each has in this relationship. It argues that ethics has the key role in establishing a resilient, comprehensive and sensitive information infrastructure. It puts forward a Bill of Rights and Responsibilities for the electronic community.
