Merleau-Ponty,Marx, and Marxism: The problem of history

At the present time, Europe, particularly eastern Europe, is still immersed in a major political transformation, the most significant such change since the Second World War, arising out of the rejection of official Marxism. This unforeseen rejection requires meditation by all those concerned with the relation of philosophy to the historical context. Marxism, that follows Marx’s insistence on the link between a theory and the context in which it arises, cannot be indifferent to the rejection of Marxist theory in practice. In respect to the usual tendency to pass rapidly over practice for a theoretical analysis of social theory, Merleau-Ponty stands out for his concern to evaluate the theoretical claims of Marx and Marxism against practice.

Violent behavior in adolescents and young adults: A person and environment model

We explore a model that examines how personal and environmental variables explain violent behavior by adolescents. Repeated interviews with youths from 1984–1992 from 10 cities across the United States provided the data. These interviews first occurred with 2,787 youths when they were adolescents (1984–85 and 1986–87) and the interviews were repeated on a subsample of 602 youths when they were young adults (1989–90 and 1991–92). Longitudinal multivariate analyses showed that almost a third of the variance in adolescent violent behaviors was predicted by a combination of personal variables (gender, substance misuse) and environmental variables (history of child abuse, stressful events, traumatic events, and city rates of unemployment). Further, almost a third of the variance in change in violent behaviors from year to year was predicted by prior violent behavior and a combination of personal variables (gender, suicidality, and substance misuse) and environmental variables (stressful events).     

Homicide by juvenile girls

We investigated offense characteristics for a national sample of 38,749 homicide arrestees identified in the FBI Supplemental Homicide Reports for 1984 and 1993. Analyses indicated little change from 1984 to 1993 in the circumstances of homicides committed by adolescent girls; however, there were consistent offense differences between girls and boys, and between girls and women. Homicides by adolescent girls were more likely than those committed by boys to involve interpersonal conflict rather than a criminal motive such as robbery. Girls were more likely than boys to use a knife rather than a firearm and their victims were more likely to be under the age of 13 years. Compared to women (18 years or older), girls were more likely to act with an accomplice and their victims were more likely to be female and between 13 and 20 years of age. Results were inconsistent with a stereotypic masculinization theory of the increase in female violence, but provide indirect support for the importance of domestic stress and relational conflict experienced by adolescent girls. Overall, this study supports the need for differentiated study of violence by juvenile girls, and for preventive interventions which target domestic and interpersonal stress.     

Dynamic models of development and the mechanistic-organismic controversy

Starting with a prototypical model of Newtonian mechanics, a sequence of dynamic models with increasing structural complexity is presented. The implicated smooth variation along a dimension of structural complexity yields dynamic models which display organismic properties such as stagewise development and emergent self-organization. Consequently, it is concluded that dynamic models of development are inherently neutral with respect to the mechanism-organicism controversy. Accordingly, a unitary research program is proposed in which these dynamic models serve as building blocks for the construction of a coherent explanatory system of development.     

Realism,instrumentalism, and the intentional stance

One of Dennett's principal arguments for an instrumentalistic construal of intentional attributions (e.g., attributions of belief, etc.) is that such attributions are environment relative. I argue that one can and should adopt a realist perspective toward such attributions, but accommodate their environmental relativity by treating intentional properties as relational properties. By doing so one acquires a useful perspective on experimental cognitive psychology; in particular, one can overcome the temptation to treat ecological accounts and information processing accounts as incompatible alternatives and come to see them as mutually supportive. Treating intentional properties as relational may be counter-intuitive, but I provide examples of how other sciences have had to treat what seem to be intrinsic properties as relational.     

Calibration of probability assessments by professional blackjack dealers, statistical experts, and lay people

The question addressed in this study is whether experts are better calibrated than lay people. We investigated how well people are calibrated when they assess the probabilities of card combinations in the game of blackjack. Three groups of subjects were used: professional dealers, statistical experts, and control subjects. The results showed that experience and statistical expertise do not make people better calibrated in this task. It is argued that the concept of calibration is not wholly appropriate to describe the obtained deviations from the normatively correct responses. This is illustrated by a discriminant analysis performed on the signed deviation scores, which resulted in an almost perfect separation of the three groups, although they were overlapping with respect to calibration.     

Organizational factors and work involvement

The aim of this paper is to describe a study which investigated the influence of organizational factors on job involvement and specialization involvement. It was hypothesized that rank, self-expression, participation in decision making, and career factors affect job and specialization involvement. The independent variables were chosen by considering an extension of Schein's (1971, Journal of Applied Behavioral Science, 7, 401–426) “career cone” concept. The hypotheses were tested using a sample of Australian Army officers (N = 384) in a questionnaire survey. The results showed that job involvement is associated primarily with self-expression, although the latter is influenced in turn by participation in decision making, and that specialization involvement is associated with both self-expression and career factors. Rank does not affect either involvement variable. It was concluded that Schein's concept is a useful guide to theory and research on career attitudes. The results support the proposition that job and specialization involvement are distinct constructs. Implications for organizations are discussed.     

The effects of situational performance constraints on intrinsic motivation and satisfaction: The role of perceived competence and self-determination

Situational performance constraints, task interest, and pay contingencies were manipulated in a laboratory study in order to investigate the cognitive mechanisms associated with the previously observed detrimental effects of constraints on affective task reactions. It was hypothesized that feelings of task competence and self-determination would account for both the direct and the interactive effects of constraints on motivation and satisfaction. The results of the study indicated that despite the fact that participants' performance was being constrained and they were aware of these constraints, the mere presence of the constraints alone failed to result in lower levels of satisfaction or motivation on a proofreading task. Post hoc analyses suggested that the constraints, in fact, led to negative affective task reactions when they also reduced participants' feelings of competence and self-determination. Interestingly, participants' generalized locus of control was associated with such effects. Internals tended to maintain stronger feelings of competence and self-determination than externals in the presence of constraints, thereby also maintaining greater motivation and satisfaction.     

A signal detection framework for the evaluation of probabilistic forecasts

In this paper I formulate an approach for evaluating probabilistic forecasts in terms of signal detection theory. Signal detection theory provides a powerful perspective for this type of problem, and a rich empirical background including methodological tools as well as an extensive body of research in many domains. I propose procedures which emphasize the maximization of expected utility for the decision maker who uses the forecasts. Further, I suggest approaches to obtaining indices of calibration and resolution within this framework. I also present arguments that the proposed indices will exhibit the same basic properties as do decompositions of Brier's (1950, Monthly Weather Review, 78, 1–3) mean probability score. However, the properties may be reflected in different ways, and hence, the present methods may lead to different conclusions about forecasting ability. Finally, I argue that the use of an expected utility loss function makes this approach more appropriate for practical applications as well as for theoretical research than other procedures with more arbitrary loss functions.
