Perceptions of Violence and Crime as Aggression by Turkish—Islamic Families in Johannesburg

This study explored perceptions of aggression of Turkish-Islamic families with adolescent children in a large South African city. Participants were from four Turkish families with adolescent children (father = 4, mothers = 4; children = 5). Data were collected via interviews and analyzed. The families considered aggression to comprise crime and violence. They also considered it a universal phenomenon.     

On the logic of psychoanalytic theory

Psychoanalytic theory shows some specific features and problems. It exists in a number of variations, according to different schools as well as cultural and subcultural conditions, with different understandings even of core concepts. Instead of producing definite knowledge, results remain uncertain. They vary in use and imply a permanent reworking of ideas and conceptions. This is the effect of the kind of theory psychoanalysis has to use. Since psychodynamics are a special kind of heterogeneous, changing, always different, emergent-in a word, autopoietic-reality, psychoanalysis cannot use the methods of a denotative theory (algorithmic reduction leading to strictly defined and formulated calculations) but has to use connotative theories. Connotative theories use open concepts which provide an active and flexible access to autopoietic reality. They are able to cope with the difference between singularities as well as with the distance between general logic and empirical reality. Problems tied to this possibility are structural fuzziness, a dependence on forms of use, multiple paradigms and difficulties in legitimation and balance of theories. This causes problems of institutionalisation. These problems are not a sign of immaturity but the normal way in which connotative theories appear and develop. They can therefore not be eliminated but only be treated in a better way.     

Causal implications of Jaśkowski

Part 1 describes Stanis?aw Ja?kowski's concept of defining some often used con ditionals, namely, factorial, ewfficient and definitive implications. Part 2 contains the results strictly connected with the theory of the above implications.     

The effect of manipulated success ratios on task preference

The hypothesis that success influences task preferences was tested by subjecting 230 Ss to three different success-failure reinforcement schedules and observing subsequent preferences for the tasks concerned. Success ratios of 85-15%, 70-30%, and 50-50% in tasks dealing with unpreferred stimuli were used. Results supported the hypothesis: the probability of change in task preference was greatest under high success reinforcement ratio conditions.     

A model relating transfer of learning and correlation

The theoretical and practical importance of a double undertaking is discussed: the development of learning and transfer taxonomies with psychometric relevance and the building of psychometric classificatory systems with implications for learning and instruction. Psychometric classifications of human performances are most often based on the covariation of individual differences. The model presented justifies the expectation that the transfer from learning one task to learning another is linearly dependent on the coefficient of intercorrelation between the two tasks when the coefficient is corrected for attenuation. Two studies so far have explicitly confirmed the main deductions from this model. Contrary to the predictions, however, the regression curves yielded negative intercepts. Two empirically testable explanations are offered, one of which would be in full accordance with the model, while the other would call for a further assumption.     

Prevalence of ADHD and comorbid disorders among elementary school children screened for disruptive behavior

In the context of a school-based prevention of conduct disorder program, 7,231 first- through fourth-grade children were screened for cross-setting disruptive behavior. Frequencies of DSM-III-R psychiatric disorders and patterns of comorbidity were assessed. We also examined the association of psychiatric diagnosis with child and parent characteristics to determine differential risk based on diagnostic subgroups. Attention deficit hyperactivity disorder (ADHD) and oppositional-defiant disorder (ODD) were the most frequent diagnoses. Mood and anxiety disorders were infrequent as single diagnoses. Patterns of comorbidity demonstrated that both externalizing and internalizing disorders commonly cooccurred with ADHD. More severe degrees of psychopathology and psychosocial risk accrued to the subgroup of youths with ADHD plus a comorbid externalizing disorder.This study was supported by grant MN-46584 from the National Institute of Mental Health.     

the role of opportunity structures in older women workers' careers

This article describes contextual factors that exert influence on whether, when, and how people retire. The authors use opportunity structures as a framework for describing these processes. Interview data were gathered from 21 late‐career women; 2 illustrative cases depict differing career circumstances. Several important contextual factors were identified, including organizational membership, occupational membership, work peers, and the history of opportunities. Depending on the circumstances, these factors can enhance or limit the range of retirement‐related options. Employment counselors can help expand this range by advocating training and job placement centers, examining norms and combating stereotypes, and encouraging job redesign.
