Models for normal intuitionistic modal logics

Kripke-style models with two accessibility relations, one intuitionistic and the other modal, are given for analogues of the modal systemK based on Heyting's prepositional logic. It is shown that these two relations can combine with each other in various ways. Soundness and completeness are proved for systems with only the necessity operator, or only the possibility operator, or both. Embeddings in modal systems with several modal operators, based on classical propositional logic, are also considered. This paper lays the ground for an investigation of intuitionistic analogues of systems stronger thanK. A brief survey is given of the existing literature on intuitionistic modal logic.     

An ethnomethodological clarification of Husserl's concepts of “regressive inquiry” and “Galilean physics” by means of discovering praxioms

This paper offers an ethnomethodological clarification of Husserl's concepts of Galilean physics and regressive inquiry. It employs the reader's textual-practical operationalization of these concepts. With the use of a simple optical prism as a perspicuous case of a scientific instrument, the reader will be asked and instructed to make a self-reflexive inquiry into the practical contingencies of the prismatic field of reflection. The reader will discover that the geometric structures of the reflective field of the prism is an achievement and formalization of the reader's own operatlonalizations. I named these discoverable discovering operationspraxioms or practical axioms — the pre-scientific contingencies of the geometric structures of prismatic reflection.I would like to thank Mike Lynch, Eric Livingston, George Psathas and Shelley Schweizer-Bjelic for their comments.     

On the essence of empty properties

This paper deals with generalisations of modally based criteria for determining whether a given property is essential to an individual to the case of generic essences. These criteria usually presuppose extensionally individuated properties. The limitations of their generalisations are demonstrated using the case of the necessarily empty individual property and the necessarily empty individual office. I do not present a novel stance on the discussion of individual essences. The novelty of this paper lies in its claim that none of these criteria can be generalised to generic essences.

     

How do Lithuanian adolescents address identity questions? A four-wave longitudinal study on change and stability in identity styles

Abstract

The present investigation evaluated multiple patterns of change and stability in Berzonsky’s identity styles (informational, normative, and diffuse-avoidant) in a four-annual-wave longitudinal study with 468 adolescent boys and girls from Lithuania. A combination of mean level changes, high rank-order stability, and high profile stability has been found in this study. First, levels of informational and normative identity styles remained stable for girls, but decreased significantly for boys; levels of diffuse-avoidant identity styles remained stable for girls and boys. Second, the rank-order stability of the normative and diffuse-avoidant styles was lower for boys, than for girls. Third, the mean profile stability was high for girls and moderate for boys. In general, our findings highlighted substantial gender differences in multiple indices of change and stability of identity styles.     

A Short Measure of the Revised Reinforcement Sensitivity Theory – RSQ17

The need for a research and practical tool, such as a short, reliable, and valid personality assessment test, suggests researchers to create shortened versions of original instruments. Reinforcement sensitivity questionnaire (RSQ) was created in line with some basic premises of revised Reinforcement sensitivity theory, which proposes three motivational and emotional systems: Behavioral inhibition system (BIS), responsible for scanning environment for potential threats, Behavioral activation system (BAS), responsible for aproaching behavior, and the Fight/Flight/Freeze system (FFFS), responsible for behavior in the present threat. RSQ comprises five scales: BIS, BAS, Fight, Flight, and Freeze. The aim of this study was to develop a short version of RSQ, which would be beneficial to both research and practical purposes. Item response theory analyses were used for item selection. The study comprised two samples of participants, whereby Sample 1 (N = 837, 34.6% male, aged 18 – 82, M = 31.63, SD = 13.54) served as the derivation sample, while Sample 2 (818 participants, 43.6% male, 18?75 years, M = 29.65, SD = 12.52) served as validation sample. Factorial validity of the short RSQ was examined on both Sample 1 and Sample 2. Convergent and divergent validity of the short RSQ was examined using RST-PQ, Jackson-5, BIS/BAS scales, and Big Five Inventory. The results point to satisfactory internal consistency, factorial validity, and construct validity of the short RSQ, suggesting that it is an adequate measure for research settings or other contexts which require the use of short personality questionnaires.     

Chemosignalling effects of human tears revisited: Does exposure to female tears decrease males’ perception of female sexual attractiveness?

Gelstein et al. reported the results of three experiments suggesting a dampening influence of inhalation of female emotional tears on males’ arousal and perception of female sexual attractiveness, specifically in non-sexual situations. This prompted the hypothesis that crying exerts its influence on others not only via the auditory and visual mode but also via chemosignals. In three studies, we attempted to replicate and extend Gelstein et al.’s findings by including an additional condition with irritant tears, by using pictures of sexually attractive women, and by testing related hypotheses on the pro-social effects of exposure to tears. All three studies, separately or combined in a meta-analysis, failed to replicate the original inhibitory effects of tears. In addition, sniffing tears did not affect measures of connectedness, aggression and pro-social behaviour. It is concluded that the effects of female tears on male arousal and perception of female sexual attractiveness, if any, are very weak at best. Rather, it seems that crying exerts its strong inter-personal effects through the visual and auditory sensory channels.     

Beliefs in Equality for Women and Men as Related to Economic Factors in Central and Eastern Europe and the United States

Do economic indicators predict the general level of support for gender equality? This question was investigated in a sample of countries in Central and Eastern Europe, a region that has been undergoing rapid economic changes since the early 1990s. In this overall sample of male and female college students from ten countries, including the United States as a comparison, the predicted association between stronger beliefs in gender role egalitarianism and positive economic factors was generally supported. Also, consistent with other research, women were more in support of gender equality than men were. There was no support for a predicted trend in less support for gender equality over the time period of the present study.     

Paul Lazarsfeld and Polish sociology: A historical record of contact,perception, and impact

This paper records the Polish aspects of P. F. Lazarsfeld's sociointellectual biography and examines his impact on Polish sociology. The analysis is divided into three chronological parts. In the 1930s, Lazarsfeld's empirical work inspired Polish sociologists in their studies on unemployment. In the late 1950s and 1960s, his model of empirical social research shaped the style of sociological practice in Poland. In the 1990s, some of Lazarsfeld's substantive contributions, mainly in the area of election studies, were taken up in Polish sociology. Lazarsfeld's influence on Polish sociology was conditioned by changes in Polish society and sociology, which is emphasized in this analysis. © 1998 John Wiley & Sons, Inc.
