On tests for correlated proportions in the presence of incomplete data

This paper proposes test statistics based on the likelihood ratio principle for testing equality of proportions in correlated data with additional incomplete samples. Powers of these tests are compared through Monte Carlo simulation with those of tests proposed recently by Ekbohm (based on an unbiased estimator) and Campbell (based on a Pearson-Chi-squared type statistic). Even though tests based on the maximum likelihood principle are theoretically expected to be superior to others, at least asymptotically, results from our simulations show that the gain in power could only be slight.     

Smoking and pain--a method of limits and sensory decision theory analysis

The effects of tobacco smoking on responses to electrical stimulation were studied according to a Method of Limits (ML) threshold analysis and a Sensory Decision Theory (SDT) analysis. For the ML procedure, Detection Threshold (DT), Pain Threshold (PT) and Tolerance Level (TL) measures were obtained. For the SDT procedure, nonparametric estimates of capacity to discriminate between stimulus intensities (P(A)) and response criterion (B) were calculated. There was no main effect of tobacco smoking on responses to electrical stimulation. Males had consistently higher ML thresholds than females in both the NS and S condition. Males also tended to increase in DT and PT after smoking. From a comparison between the effects of smoking on ML and SDT measures it was suggested that PT is related mainly to sensory factors and TL to response factors.     

The St. Pauls' riot: An explanation of the limits of crowd action in terms of a social identity model

The paper contains a detailed study of the St. Pauls' riots of April 1980. Particular attention is paid to the limits of participation in the event and the limits of crowd action. It is argued that these limits show clear social form and cannot be explained in terms of the individualistic theories that dominate crowd psychology. Instead a model of crowd behaviour based on the social identity model is advanced to account for the observations. It is concluded that crowd behaviour is more sophisticated and creative than hitherto allowed and that the neglect of this field should be remedied.     

Maternal and adolescent depressive symptoms and family conflict: An autoregressive cross-lagged examination of competing models in multi-stressed mothers and adolescents

Maternal and adolescent depression are challenges that often co-occur. Many studies have drawn bivariate associations between maternal depressive symptoms, adolescent depressive symptoms, and family conflict, but few have examined reciprocal effects. Even among extant studies, there is a lack of clarity related to directionality of influence. Three competing theoretical models may explain the relationship between maternal depressive symptoms, adolescent depressive symptoms, and family conflict, and these processes may differ by adolescents’ sex. Using three time points of data from 187 diverse mother-adolescent dyads, we fit a taxonomy of autoregressive cross-lagged structural equation models to simultaneously evaluate the competing theoretical models and also examine differences by sex using multiple-group analyses. Results indicate a symptom-driven model whereby adolescent depressive symptoms predicted increases in family conflict. Sex differences were also found. For males, but not females, greater adolescent depressive symptoms predicted subsequent increases in maternal depressive symptoms, which then predicted lower family conflict—possibly indicating maternal disengagement/withdrawal. Our findings suggest addressing adolescent depressive symptoms in order to prevent family conflict and that distinctive targets for the prevention/intervention of family conflict should account for differences by adolescents’ sex.     

Take care of egotism,and redemption will take care of itself: Comments on Tracy Llanera's Richard Rorty: Outgrowing modern nihilism

This commentary critically examines two facets of Tracy Llanera's recent book Richard Rorty: Outgrowing Modern Nihilism. First, it considers her interpretation of Richard Rorty's redemptive project. It argues that, while Llanera succeeds in resolving tensions in Rorty's public-private distinction, her account downplays the role of abnormal discourse within projects of self-creation. Second, it raises several questions about Llanera's strategy for situating this redemptive project within debates concerning existential nihilism. On her view, one ought to follow Rorty in addressing the problem of egotism instead of the problem of nihilism, since the former is prior to the latter. But it is not clear who counts as an egotist, or why egotists are especially prone to becoming nihilists. Moreover, there are reasons to think that egotism and nihilism are fundamentally different kinds of problems.     

Revival of psychology in former Czechoslovakia and the contemporary Czech Republic after the fall of Totalitarian communist regimes

After the general societal and political change in November 1989 in Czechoslovakia, the subject “History of Psychology” became the stable component of curriculum of studying psychology at the Department of Psychology of Faculty of Arts of Charles University in Prague. The author of this paper has taught “History of Psychology” in Czech since 1998 for more than 20 years all students of psychology and he is teaching this subject the students of ERASMUS+ program from whole Europe, studying at Charles University in Prague, now. Indivisible part of the curriculum is represented by the history of Czechoslovak and Czech psychology. In References, the most important publications in the field of history of Czechoslovak and Czech psychology are presented.
