Predicativity and Structuralism in Dedekind’s Construction of the Reals

It is a commonly held view that Dedekind’s construction of the real numbers is impredicative. This naturally raises the question of whether this impredicativity is justified by some kind of Platonism about sets. But when we look more closely at Dedekind’s philosophical views, his ontology does not look Platonist at all. So how is his construction justified? There are two aspects of the solution: one is to look more closely at his methodological views, and in particular, the places in which predicativity restrictions ought to be applied; another is to take seriously his remarks about the reals as things created by the cuts, instead of considering them to be the cuts themselves. This can lead us to make finer-grained distinctions about the extent to which impredicative definitions are problematic, since we find that Dedekind’s use of impredicative definitions in analysis can be justified by his (non-Platonist) philosophical views.

It is Better to Receive than to Give: Advice Network Effects on Job and Work-Unit Attachment

Purpose  The purpose of this paper was to investigate the relationship between advice-giving, advice-receiving, and employee work attitudes. We argue that (1) both advice-receiving and advice-giving will be positively related to job involvement; (2) advice-receiving will be more strongly associated with work-unit commitment than advice-giving; and (3) job involvement will mediate the relationship between advice-receiving and work-unit commitment. Design/methodology/approach  We conducted an empirical study of admissions department employees at a large university in southwest Pennsylvania in the United States. Respondents completed surveys which included questions related to demographics, social network ties, and attitudes. Findings  We found that while advice-giving and advice-receiving were positively related to job involvement, only advice-receiving was positively related to work-unit commitment. Job involvement fully mediated the relationship between advice-receiving and work-unit commitment. Implications  Our study (1) shows that advice-giving and advice-receiving are related to important work-related attitudes in organizations; (2) highlights the importance of the directionality of advice flow, as employees who received as opposed to provided advice tended to have higher levels of work-unit commitment; and (3) demonstrates that social network ties were related to work-unit attachment through job involvement. Originality/value   We examine job involvement and work-unit commitment using a social network analysis thus providing new insights about the relationships between advice-giving, advice-receiving and these important variables. An earlier version of this paper won the Best Paper Award at the 2005 Southwest Academy of Management Conference. The authors would like to dedicate this paper to Margie Jonnet.     

An Oral History of the National Society of Genetic Counselors

Master's level genetic counselors formed a professional society in 1979, 8 years after the first master's degree training program graduation. This paper presents an oral history of the early years of the National Society of Genetic Counselors (NSGC), reviews the symbiotic development and definition of a profession and a professional society, and discusses events and achievements attributed to the NSGC since its incorporation. This retrospective historical account is based on personal and collective oral history, NSGC archival material and other sources.     

Racial differences in intelligence: The importance of the executive system

The race-IQ controversy arose at a time when psychometric views of intelligence dominated. Little attention was paid to more process-oriented models in spite of the fact they provide alternative perspectives on the causes of individual differences in problem-solving. We hypothesized that much of the IQ spread commonly observed between black and white children can be attributed to differences in components of their executive systems, including the knowledge base, control processes, and metacognitive states. To test this possibility, black and white children who differed significantly on fluid and crystallized intelligence were tested on multiple tasks reflecting components of the executive systems as well as on perceptual efficiency tasks. Striking group differences were observed in metamemory, stragegy use, and general knowledge, but few reliable differences were found in perceptual efficiency. Regression analyses showed that different factors predicted fluid and crystallized intelligence, with metamemory predicting the latter but not the former. An implication of these findings has potential educational significance: training directed at executive skills, introduce at an early age, might elevate learning and problem-solving skills in black children, thereby reducing racial differences in crystallized intelligence.     

Testing Theoretical Explanations of Intention to Seek Care for a Breast Cancer Symptom1

The purpose of this research was to test theoretical explanations of intention to seek care promptly for a breast cancer symptom. Psychosocial variables (affect, expectations, values, and norms), habit, and facilitating conditions (e.g., insurance) regarding care seeking were proposed to influence intention to seek care promptly. Whether psychosocial variables and habit influenced intention directly or in interaction with facilitating conditions remained unclear. Other variables (i.e., clinical and demographic) were proposed to influence intention by mediation through the theoretical variables. Community-dwelling women without history of breast cancer (N= 99) responded to a questionnaire to assess study variables. In a hierarchical set regression, intention was first regressed on psychosocial variables, habit, and full insurance coverage for care, then on terms representing interactions of insurance coverage with psychosocial variables and habit, and lastly on clinical and demographic variables. Findings revealed that (a) anxiety (measure of affect), utility, (the product of expectations and values), and habit were related to intention, (b) having full insurance coverage did not moderate these relationships, and (c) after controlling for theoretical variables, family history of breast cancer was related inversely to intention. Implications for theory, research, and practice are delineated.     

Sexual assault history and use of health and mental health services

A history of sexual assault may be associated with increased current use of mental health and medical services because of the psychologically and physically disruptive consequences of assault. To test this hypothesis, we estimated rates of mental health and medical services use among 2560 randomly selected community residents, 343 of whom had been sexually assaulted. Sexual assault was associated with seeking both forms of care. Controls for demographic variables, psychiatric diagnosis, health status, and insurance suggested that assault increases use indirectly, through poor mental and physical health. Uninsured, assaulted respondents were especially likely to consult medical providers. Respondents assaulted during childhood were particularly likely to seek mental health care. Assault was more common among mental health service users than nonusers, and among women using medical services compared to female nonpatients. The high prevalence of assault among service users underscores the need for providers to recognize and treat sexual assault-related problems.     

Sex differences in dominance behavior

The effect of the status characteristic of sex on dominance behavior was investigated as a function of a challenger's sex and in relation to one's sex-role orientation. Dyads composed of a student and a confederate recorded individual preferences, then joint decisions, for the more attractive picture of 20 pairs of pictures. The number of challenges a student sustained each time a disagreement occurred regarding the more attractive picture of a pair was recorded. Males withstood significantly more challenges against their preferences than females did (p<.006). However, no differences were found as a function of the sex of one's partner; nor did the Attitudes toward Women Scale (AWS) prove to be a good predictor of dominance. Results were discussed in terms of predictions made by the theory of status characteristics.This report is based on a master's thesis written by the first author under the sponsorship of the second and submitted in partial fulfillment of the requirements for the MA degree at the Graduate School of the University of Alabama. Portions were presented as part of of the paper session Compliance-Conformity/Altruism-Helping Behavior at the annual meeting of the Southeastern Psychological Association, New Orleans, March 1976.The authors would like to express their appreciation those who served as confederates in this study: Jim Dodds, Rochelle Hanan, Eunice Fogarty, and Rex Hall.     

Gender differences in early risk factors for adolescent depression among low-income urban children

One component of a model by Nolen-Hoeksema and Girgus, who propose that risk factors for adolescent depression are more common in girls than in boys during childhood, was tested with 85 low-income, urban, African American and Latino kindergarten through fourth grade children who completed inventories of depression, stress, attributional style, gender role, and body image. Endorsing two of three predicted risk factors, girls reported slightly poorer body image and identified more strongly with a feminine gender role. Boys, however, reported a more negative attributional style. Feminine gender role was not associated with body image or negative attributional style. The applicability of the proposed model to a low-income, ethnic minority, urban population is discussed.     

Gender similarities and differences in children's social behavior: finding personality in contextualized patterns of adaptation

This research examined how a contextualist approach to personality can reveal social interactional patterns that are obscured by gender comparisons of overall behavior rates. For some behaviors (verbal aggression), girls and boys differed both in their responses to social events and in how often they encountered them, yet they did not differ in overall behavior rates. For other behaviors (prosocial), gender differences in overall rates were observed, yet girls and boys differed more in their social environments than in their responses to events. The results question the assumption that meaningful personality differences must be manifested in overall act trends and illustrate how gender differences in personality can be conceptualized as patterns of social adaptation that are complex and context specific.
