The State of Play in Poland's Unconventional Shale and Oil Development

Following initial geological assessments, Poland was identified as having one of the largest reserves of unconventional natural gas in the European Union. The Poles, seeking to diversify their energy sources, met the news with tremendous fanfare. However, shale gas development often requires voluminous speculative activity before the gas can be successfully extracted – an activity which has been rare in Poland, where a lack of critical infrastructure coupled with bureaucratic red tape in the permission process has led to slow growth in exploration activities. This article examines the current situation in Poland's unconventional gas and oil development.     

Nonresident Fathers’ Parenting,Maternal Mastery and Child Development in Poor African American Single-Mother Families

This study examines the relationships between and among economic hardship, mothers’ depressive symptoms, nonresident fathers’ parenting, mothers’ parenting and mastery, and their children’s behavioral and cognitive development in poor African American single-mother families. Informed by stress-coping and family process theoretical perspectives, this study estimates the effects of nonresident fathers’ parenting and maternal mastery on child developmental outcomes. Analyses use the first three waves of longitudinal data from a subsample of single, African American and noncohabiting mothers with low income in the Fragile Families and Child Wellbeing Study. Results suggest that nonresident fathers’ parenting is indirectly associated with children’s behavior problems and cognitive development transmitted through mothers’ parenting and mastery. Maternal mastery is also found to be one of the most influential predictors of both developmental outcomes of children. Policy and practice implications of these findings are discussed.     

Broadening gender self-categorization development to include transgender identities

Research on gender in psychology has increasingly affirmed diversity in gender, with recognition of binary and nonbinary transgender experiences. However, gender has been presumed to be cisgender (congruent with sex) and binary (either male or female) in classical developmental theories. In response, this review engages in a critical analysis of classical gender development theory informed by findings about gender from research on transgender identities. Under analysis was the concept of gender self-categorization in classical theories of gender development including cognitive developmental theory, developmental gender schema theory, and social cognitive theory. Novel theoretical approaches are then outlined to situate recent advancements alongside classical theory. Conclusions are then drawn with brief recommendations for research methods that aim to include binary and nonbinary transgender participants. Drawing on the findings of this review it has been shown that gender self-categorization is often implicitly presumed to be cisgender identification. To overcome this bias, it is suggested that greater attention to specific gender self-categorization mechanisms are needed to open opportunities to include transgender experiences.     

Assessing the language of 2 year-olds: From theory to practice

Early screening for language problems is a priority given the importance of language for success in school and interpersonal relationships. The paucity of reliable behavioral instruments for this age group prompted the development of a new touchscreen language screener for 2-year-olds that relies on language comprehension. Developmental literature guided selection of age-appropriate markers of language disorder risk that are culturally and dialectally neutral and could be reliably assessed. Items extend beyond products of linguistic knowledge (vocabulary and syntax) and tap the process by which children learn language, also known as fast mapping. After piloting an extensive set of items (139), two phases of testing with over 500 children aged 2; 0–2; 11 were conducted to choose the final 40-item set. Rasch analysis was used to select the best fitting and least redundant items. Norms were created based on 270 children. Sufficient test-retest reliability, Cronbach's alpha, and convergent validity with the MB-CDI and PPVT are reported. This quick behavioral measure of language capabilities could support research studies and facilitate the early detection of language problems.     

The effect of artificial light on bat richness and nocturnal soundscapes along an urbanization gradient in an arid landscape of central Peru

Urbanization usually reduces bat richness; however, the presence of green areas within cities and peripheral rural areas in arid ecosystems may provide microhabitats for some species. Light pollution is a major feature of urbanization, but its impact on bat behavior appears to be species-specific and previous studies have documented contrasting responses. Moreover, the effect of urbanization on bat species has been poorly studied in arid regions. We assessed the effect of artificial night light intensity (as a proxy of urbanization) on both bat occupancy and the acoustic space used (ASU) in an urbanization gradient in Peruvian central coast, based on passive acoustic recorders. We collected 26,169 recordings from 19 sites which resulted in 579 independent detections of 15 bat species. Variation in both ASU and species richness was best explained by artificial night light intensity. Species-specific effects of the artificial night light intensity based on a multi-species occupancy modeling showed that this covariate had a negative effect on occupancy for most of the bat species (12 species). ASU and both observed and posterior bat species richness were positively correlated, suggesting that ASU can be used as a proxy of bat richness. This study provides evidence that both bat richness and occupancy decrease with artificial light intensity; nevertheless, eight species used urban areas, similar to results found in other cities around the world.
