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.     

Difficult differences pave the creative road from diversity to performance

In this article, we argue that engagement with differences is important for the relationship between diversity and organizational performance. This importance is explained by the increased potential for creativity and innovation coming out of working in diverse teams. We recognize that difference and diversity can act as a double-edged sword for creativity and also contend that such differences are a fundamental condition for novelty and value to emerge. It is because of differences and not despite them that we create at individual, group, and organizational levels and a European approach to this topic – given Europe's history and philosophical traditions – recognizes the major role played of creative tensions and even conflict in innovation and in society more broadly. In this paper, we review literature that relates creativity and business performance, creativity, and diversity and examine the role of disagreement and tension, both conceptually and based on empirical evidence. We conclude by stressing the point that creativity often comes out of difficult differences, a European lesson that is easily forgotten, in Europe as well as globally.     

Partial Least Squares: A First-order Analysis

We compare the partial least squares (PLS) and the principal component analysis (PCA), in a general case in which the existence of a true linear regression is not assumed. We prove under mild conditions that PLS and PCA are equivalent, to within a first-order approximation, hence providing a theoretical explanation for empirical findings reported by other researchers. Next, we assume the existence of a true linear regression equation and obtain asymptotic formulas for the bias and variance of the PLS parameter estimator     

Representations of Jewish Childhood From 1950s Communist Romania in Memoirs by Women Émigré Authors to the United States

ABSTRACT

This article examines the memoirs of three Jewish women – Marianne Hirsch, Anca Vlasopolos, and Haya Leah Molnar – to understand how they remembered childhood in 1950s communist Bucharest. I first show how Marianne Hirsch’s part-memoir, part-critical book, Family Frames, uses her personal experiences to theorize tropes of transcultural dislocation as specific features of post-World War II Jewish children’s identities in 1950s Romania. I analyze how these tropes equally permeate the memoirs by two of her generation’s peers, Anca Vlasopolos and Haya Leah Molnar, highlighting how the two authors deploy them in their narratives. Overall, I show that writings of one’s 1950s childhood experiences in Bucharest by Jewish emigrées to the US offer new alternative discourses about facing the past and the present in Eastern Europe and the US by the tropes of initial transcultural, dislocating experiences at the start of their lives.     

The reconfiguration of social movements in post-2011 Romania

ABSTRACT

Since 2011, a series of citizen mobilizations have emerged in Romania, from local replicas of the ‘Occupy’ movement to the 2017 and 2018 mass protests against corruption. In this article, we develop three arguments for a better understanding of the successive waves of protests that have shaken the Romanian social and political landscape since 2011. First, while each protest has a specific claim and target, the forms of commitments, repertoire of actions and relationship to politics point to clear continuities between protest events that should be analyzed as part of the same cycle of protests. Second, while some analyses have emphasized the specificities of the Romanian context, we maintain that the actors and dynamics of this cycle of protest are simultaneously deeply national, embedded in the mutations of Eastern European civil society, and in resonance with the post-2011 global wave of movements. Third, while it is indispensable to analyze these citizen mobilizations as a whole, it is equally important to understand that they result from the convergence of diverse activist cultures, from left-wing autonomist activists to right-wing citizens and even nationalist militants. Each of these activist cultures has its own logic of action and its vision of democracy and of politics.     

Introduction

The present study investigates whether hypothesized cognitive mechanisms of change mediate the efficacy of cognitive-behavioral therapy (CBT) delivered online for treating depression and anxiety disorders. Articles were included by searching MEDLINE, PsychInfo and PsychArticles databases from January 1980 to March 2011. The inclusion criteria were as follows: (a) randomized clinical trials investigating the role of CBT delivered online, (b) patient sample had clinical or subclinical intensity emotional problems, (c) at least one measure of cognitions was included, (d) the inclusion of a control group, and (e) sufficient data provided to allow calculation of effect sizes. Eleven articles were selected. Results revealed a moderate overall effect size of CBT (d = .67, P < .05) on the combined cognitive and emotional outcomes. A positive impact of online CBT on cognitive factors (d = .69, P < .05) and emotional outcomes (d = .63, P < .05) was independently demonstrated. In conclusion, cognitive-behavioral therapy delivered online can be used as an efficacious treatment for patients with emotional disorders. Assuming causal effects, the data indicate that cognitive factors are an important mechanism of change in online CBT. Future online CBT focusing on changing cognitions are likely to be efficacious.     

On units of Analysis and Creativity Theory: Towards a “Molecular” Perspective

This article addresses the issue of units of analysis and atomistic models in psychology taking creativity research as a case study. A classic typology in this area, initially proposed by Rhodes (1961), distinguishes between the four P's of creativity: person, process, product, and press (environment). Continuing an effort to rewrite this basic language of the discipline from a cultural psychological perspective in the form of five A's (actor, audience, action, artefact, affordances), the discussion here focuses on bringing relationships to the fore within this framework and problematising strict distinctions between each of the five elements. A closer look at the five A's of creativity, drawing on theoretical considerations and illustrated by interviews with creators working in different domains, reveals the permeable borders surrounding these units and challenges clear divisions between actors and audiences, action and artefacts, actors and artefacts. In the end, it is argued that creative phenomena cannot be properly understood and studied outside of their integrated and dynamic totality defined as a creativity complex. Implications of adopting this “molecular” perspective for theory and methodology are discussed.
