On Old-Fashioned Versus Modern Homonegativity Distinction: Evidence From Poland

Psychological research on prejudice against homosexuals distinguishes between old-fashioned (traditional) and modern (contemporary) homonegativity, which differ with regard to their content, correlates, and consequences. The current research offers evidence for the validity of old-fashioned versus modern homonegativity distinction in the post-communist, East European context. In Studies 1 and 2 (Ns = 295 and 327, respectively) the Polish adaptations of the non-gendered and gendered Homonegativity Scale (Morrison, Parriag, & Morrison, 1999) and the Modern Homonegativity Scale (Morrison & Morrison, 2003) were developed. Furthermore, divergent (discriminant) validity of traditional and contemporary anti-homosexual prejudice was demonstrated. Old-fashioned and modern homonegativity exhibited differential relationships with social distance and support for same-sex couples’ relational rights.     

Radio Free Europe and the Catholic Church in Poland During the 1950s and 1960s.

A review of the literature on Radio Free Europe’s role throughout the Cold War reveals its underdeveloped historiography. Yet, how valuable are RFE’s reports and broadcasts as a tool for historical exploration? Drawing on a wealth of materials from Polish programming, this analysis uses the case study of the role of the Catholic Church in Poland throughout the 1950s and the 1960s, to appraise not only the content of RFE reports but also the extent to which they can be used as a historical tool. The reports reveal, for example, that the Church became politically active already in the mid 1960s during its struggle with the Communist regime over the Millennium anniversary celebrations and the issue of Poland’s Western territories. This analytical framework allows for an examination of RFE’s comments in terms of what they might tell us about what really happened, and in terms of what they actually tell us about the station’s perceptions of what happened. The station’s position as an observer, critic and participant in the turmoil of the Cold War, gave it a distinct ability to access both the realities behind the Iron Curtain and the Western perceptions of what was happening in the satellite countries.     

Nonparametric estimation of the ROC curve based on smoothed empirical distribution functions

The receiver operating characteristic (ROC) curve is a graphical representation of the relationship between false positive and true positive rates. It is a widely used statistical tool for describing the accuracy of a diagnostic test. In this paper we propose a new nonparametric ROC curve estimator based on the smoothed empirical distribution functions. We prove its strong consistency and perform a simulation study to compare it with some other popular nonparametric estimators of the ROC curve. We also apply the proposed method to a real data set.     

ADVERTISING, CONCENTRATION AND PROFITABILITY IN MANUFACTURING

This paper predicts an inverted-LI relationship between concentration and advertising only for oligopolistic industries facing relatively less elastic demand curves. It rejects the inverted-LI theory based on the hypothesis that the large firms collude and lends empirical support to the idea that causation runs from Concentration to advertising intensity. By confirming that the effect of advertising on profitability is significant and greater for industries producing homogeneous goods than for those producing heterogeneous goods, this study fails to support the barriers-to-entry hypothesis.     

Post-finasteride syndrome – does it really exist?

Abstract

Inhibitors of 5α-steroid reductase are drugs used to treat androgen-dependent conditions including prostate diseases and androgenic alopecia. Finasteride was the first on the market and is currently the most widely used inhibitor. Dutasteride was the second inhibitor to be approved and has a similar safety profile. Common adverse events of treatment consist of sexual disorders and a negative affect balance. It was described that the prolonged use of 5α-steroid reductase inhibitors in patients with alopecia can cause persistent side effects called a post-finasteride syndrome (PFS), that is not just a simple coexistence of events, but rather a definite syndrome with an iatrogenic background. PFS occurs in susceptible individuals even after small doses of the drug and can last for a long time after the discontinuation of treatment. A deterioration in the quality of life in affected individuals does not justify use of the drug. Wider recognition of PFS symptoms, its incidence, course, prevention, and treatment possibilities will allow the indications for drug use to be reconsidered and treatment to be more personalized. Knowledge about PFS will also help to provide the best treatment for affected individuals and to properly educate patients before obtaining an informed consent for therapy with 5α-steroid reductase inhibitors.     

Attachment and leader's development via experiences

Apart from biographies and memoirs of outstanding leaders, studies on the development of leaders in everyday life from childhood to maturity are rare. We propose a developmental model of leaders in which certain variables formed in early childhood are the basic components for leadership development in later life. These are a low level of trait anxiety [Spielberger, C.D. (1972). Conceptual and methodological issues in anxiety research. In C.D. Spielberger (Ed.), Anxiety: Current trends in theory and research. New York: Academic Press, vol. 1] and openness to experiences [Costa, P.T. Jr., & McCrae, R.R. (1992a). Revised NEO Personality Inventory (NEO-PI-R) and NEO Five-Factor Inventory (NEO-FFI) professional manual. Odessa, FL: Psychological Assessment Resources]. We argue that secure attachment style [Bowlby, J. (1969). Attachment and loss: Vol. 1. Attachment. New York: Basic Books] explains the formation and influence of these basic components, which in turn affect the leader's development through experience in leadership roles. Questionnaires were administered to 286 subjects. The data obtained were analyzed by structural equation modeling (SEM).The findings show that trait anxiety and openness to experience affect leaders' development via experiences. Alternative models in which formative variables may affect the magnitude and intensity of leadership experiences are discussed.

Liberalization of services in Europe: Polish perspective on economic implications of the Services Directive

The original EU Service Directive proposal met widespread opposition and was subsequently narrowed down. Some believed that the competition from the New Member States would endanger the situation of the “old” EU service providers. We assess the importance of the Service Directive for Poland and other EU members by performing a revealed comparative advantage analysis and a computable general equilibrium simulation of the outcome. The liberalization provides minimal welfare gains for Poland and the main opponents of the Service Directive, while they are expected to be higher for small economies open to trade in services.     

Annual variation in prey composition of domestic cats in rural and urban environment

The threat that domestic cats pose to wildlife has gained increased recognition by researchers and conservationists, and in this study, we investigated the seasonal variability and the effects of environment type (rural vs. urban) on the prey composition of free-ranging house cats in Poland. We analysed the variability in 307 monthly prey samples of different prey items killed by cats and brought to their owners (i.e., prey brought home by cats living in one home in one month) between 2002 and 2007 at 26 rural and urban sites. The variability in prey composition over time was analysed using additive models and canonical correspondence analysis. In total, we recorded 1348 prey items. Rodents were the most common prey in both environments, but shrews and reptiles were killed by cats more often in the rural environment while birds (mainly sparrows and pigeons) were more common in the urban environment. Additionally, prey composition changed seasonally. The pooled number of vertebrates killed by cats was largest in September and lowest in January, and rodents were killed most often in September, shrews and birds in June, and reptiles in April. The seasonal variation in the prey composition of cats was relatively high in the rural environment and more stable in the urban environment. Prey composition seemed to follow temporal and spatial variations in prey availability, thus confirming a facultative feeding strategy in free-ranging house cats.     

Effects of human-related disturbance on breeding success of urban and non-urban blue tits (<Emphasis Type=Italic>Cyanistes caeruleus</Emphasis>)

There is a need to study the effects of urbanization on wildlife in order to understand the ecological implications of increasing urbanization and find out how to reduce its threats to biodiversity. The blue tit evolved as a forest species and prefers deciduous and mixed forests, whereas its nesting in urban habitats is a more recent phenomenon. Our long-term study of blue tit populations has been conducted in two habitats: an urban parkland (frequently visited by people) and a deciduous forest outside of the city. Using linear mixed modeling, we revealed that a relationship of blue tit breeding success (and the number of fledglings) with thermal conditions in May differed between the urban parkland and the forest. While the relationship was positive in the forest, it was negative in the parkland. In addition, breeding success in the parkland increased with increasing number of rainy days in May. We argue that the main possible reason for such patterns is human activity in the parkland, which interferes with tit parental care, especially the regular feeding of nestlings, whereas it is evidently associated with weather conditions. Human disturbance in the forest is likely to be negligible.
