A model for science kinematics

A comprehensive model for describing various forms of developments in science is defined in precise, set-theoretic terms, and in the spirit of the structuralist approach in the philosophy of science. The model emends previous accounts in centering on single systems in a homogenous way, eliminating notions which essentially refer to sets of systems. This is achieved by eliminating the distinction between theoretical and non-theoretical terms as a primitive, and by introducing the notion of intended links. The force of the model is demonstrated by formally incorporating many of the important, precise meta-theoretic concepts occurring in the literature.This paper was written under DFG project Ba 678/3-2.     

Children's alcohol cognitions prior to drinking onset: discrepant patterns from implicit and explicit measures

Prior to drinking onset, children report stronger negative versus positive beliefs on self-report alcohol expectancy questionnaires, with some attenuation of this negativity as they transition into adolescence. Traditional alcohol expectancy assessments, however, capture endorsement of deliberative propositions about drinking outcomes. Measurement of implicit alcohol associations may elucidate automatic evaluations, clarifying the role of nondeliberative cognition in the initiation of alcohol use among youth. Few studies have assessed implicit alcohol cognition among children and younger adolescents, with inconsistent findings regarding the nature of these automatic associations within and between age groups. Eighty-nine 3rd and 4th graders and 91 7th and 8th graders completed an alcohol expectancy measure and two unipolar alcohol Implicit Association Tests (IAT) measuring positive and negative alcohol associations independently. On the explicit measure older compared with younger participants rated positive drinking outcomes as more likely and negative outcomes as less likely. Older compared with younger students were also more neutral/moderate in their evaluations of positive drinking outcomes. On the IATs, scores for the full sample indicated negative alcohol associations, and Negative IAT scores were higher for older compared with younger participants. However, the valence of implicit alcohol associations was qualified by the order of explicit versus implicit assessment; for those who completed the IATs prior to the explicit expectancy measure, alcohol associations were positive. Findings replicate and extend prior research conducted with preonset youth. Implications regarding the role of automatic and controlled processes in drinking onset and directions for future work on children's alcohol cognition are discussed.     

A Beta Unfolding Model for Continuous Bounded Responses

An unfolding model for continuous bounded responses is proposed, derived both from a hypothetical interpolation response mechanism and from the hypothesis of two opposite sources of item refusal being collapsed. These two sources of refusal are made explicit in a three-component Dirichlet response model and then collapsed to obtain a (two-component) beta response model. The two natural parameters of the beta are interpreted as acceptance and refusal parameters and expressed as functions of person-item distances on a latent continuum. The potentially bimodal shape of the beta is exploited to model chaotic response choices among ambivalent subjects.     

Academic achievement and behavioral health among Asian American and African American adolescents: testing the model minority and inferior minority assumptions

The present study tested the model minority and inferior minority assumptions by examining the relationship between academic performance and measures of behavioral health in a subsample of 3,008 (22 %) participants in a nationally representative, multicultural sample of 13,601 students in the 2001 Youth Risk Behavioral Survey, comparing Asian Americans (N = 408) and African Americans (N = 2,600). Specifically, the study examined associations of students’ self-reported grades with suicide risk, substance abuse, and violent behaviors. The findings revealed that high academic performance is a protective factor against behavioral health problems for both ethnic groups. The results raise questions about the focus on high achievement among Asian Americans versus academic underachievement among African Americans. Implications for theory, research, training and practice in addressing the mental health implications of achievement behavior in Asian American and African American youth are discussed.     

Cancer as a defence against depressive pain

An association between object loss and the predisposition to develop physical illness is well established in the psychosomatic literature. This paper describes a psychotherapeutic consultation with a woman who developed breast cancer after the death of her father by cancer, and the loss of her mother by dementia. Her cancer was preceded by persecutory dreams which ‘predicted” the cancer, and which ceased when the cancer was diagnosed. It is argued that the cancer represented a somatic defence against intolerable guilt and despair, which constitute depressive anxiety as described by Klein and Riviere. Cancer is felt by such patients to be preferable to grief and madness. Possible unconscious meanings and functions of the dreams and the cancer are discussed, as well as the patient's inability to avail herself of psychotherapeutic help.

Biases in the recording of performance-related information: The effects of initial impression and centrality of the appraisal task

Two variables, initial impression and rating task centrality, were hypothesized to bias the recording of performance-related behavioral incidents used by raters during appraisal. Eighty students viewed two short videotapes of a single lecturer delivering lecture segments and collected behavioral incidents (both good and bad) exhibited by the lecturer using the behavior diary format. Students were randomly assigned to a single experimental condition where both initial performance of the lecturer (good vs poor performance on the first lecture seen) and importance of the behavior collection task (high vs low rating task centrality) were manipulated. The hypothesized effects of initial impression and rating task centrality were only partially demonstrated. In particular, initial impression produced a significant contrast effect in the subsequent recording of behavioral incidents. There was no significant difference in the number of incidents collected under varying conditions of rating task centrality. However, a significant rating task centrality × initial impression interaction showed that while under low rating task centrality subjects in the negative impression condition collected more incidents than subjects in the positive condition, and the opposite effect was found for subjects in the high rating task centrality condition.
