Modernization and the logic of interorganizational networks

In this paper an attempt is made to widen the perspective under which interorganizational networks are generally seen. It is argued that both in the economy and in policy making, network phenomena are in fact becoming more prominent. This is linked to functional differentiation, a core process of societal modernization, which implies the existence of partly autonomous societal subsystems. Their emergence is closely connected with the ascendance of formal organizations, which in turn enjoy a certain measure of autonomy. In this structural context, interorganizational network following a logic of negotiation, which extends to “constitutional” issues can provide a solution to coordination problems typical of modern societies. Her research interests include sociological macro-theory, comparative social and political research, organizational and administrative sociology, and sociology of technology.     

The good,the bad and the central of group identification: Evidence of a U‐shaped quadratic relation between in‐group affect and identity centrality

The present research investigates the interrelation between two widely studied dimensions of social group identity—in‐group affect and centrality. Specifically, we test the validity of a quadratic curvilinear relation between in‐group affect and identity centrality. We propose that group members who feel either decidedly positive affect or decidedly negative affect towards their group are more likely to feel that their identity is a central component of their self‐concept relative to group members with neutral affect. We find evidence for a quadratic relation between in‐group affect and identity centrality with respect to people's cultural identity (N = 512), ethnic identity (N = 462), religious identity (N = 61, N = 384) and racial identity (N = 3600, N = 2400). Theoretical and practical implications for the measurement and conceptualization of group identification are discussed. Copyright © 2016 John Wiley & Sons, Ltd.     

Evidence for a Data-Based Environmental Policy: Induction of a Behavior-Based Decision Support System

To advise policy‐makers about possible courses of action in the environmental domain, psychological science should employ a support system that allows for evidence‐based decisions with respect to the three generic policy questions: what, where, and how. The key to such a system is a measurement instrument in which environmental motivation becomes tangible in individual actions. In this article, we provide empirical examples of such a decision support system in the environmental domain. It consists of (a) evidence about environmental motivation of persons, (b) evidence about motivation's spatial distribution, (c) knowledge about the socio‐cultural conditions that affect individuals when they translate motivation into action (i.e. structural information), and (d) a forecast of the environmental impact—the concrete conservation potential of various behaviors. Pour conseiller les décideurs à propos de lignes de conduite possibles dans le domaine de l’environnement, la science psychologique devrait utiliser un système qui tienne compte des décisions provenant des trois questions génériques suivantes: quoi, ou et comment? La clé d’un tel système consiste en un instrument de mesure dans lequel la motivation environnementale devient tangible dans les actions individuelles. Dans cet article, nous prenons des exemples empiriques de telles aides à la décision dans le domaine de l’environnement. Peut être ainsi montré a) la motivation environnementale des personnes, b) la distribution spatiale de la motivation, c) l’influence de la connaissance des conditions socioculturelles des individus quand ils transforment motivation en action (i.e. information structurale) et (d) la prévision de l’impact environnemental sur le maintien potentiel de divers comportements.     

Gustatory plasticity in C. elegans involves integration of negative cues and NaCl taste mediated by serotonin, dopamine, and glutamate

While na?ve Caenorhabditis elegans individuals are attracted to 0.1-200 mM NaCl, they become strongly repelled by these NaCl concentrations after prolonged exposure to 100 mM NaCl. We call this behavior gustatory plasticity. Here, we show that C. elegans displays avoidance of low NaCl concentrations only when pre-exposure to NaCl is combined with a negative stimulus, e.g., a repellent, or in the absence of food. By testing serotonin and/or dopamine signaling mutants and rescue by exogenously supplying these neurotransmitters, we found that serotonin and dopamine play a role during the plasticity response, while serotonin is also required during development. In addition, we also show that glutamate plays an important role in the response to NaCl, both in chemoattraction to NaCl and in gustatory plasticity. Thus, C. elegans can associate NaCl with negative stimuli using dopaminergic, serotonergic, and glutamatergic neurotransmission. Finally, we show that prolonged starvation enhances gustatory plasticity and can induce avoidance of NaCl in most gustatory plasticity mutants tested. Only mutation of the glutamate-gated Cl(-) channel gene avr-15 affected starvation-enhanced gustatory plasticity. These results suggest that starvation induces avoidance of NaCl largely independent of the normal gustatory plasticity mechanism.     

Individual differences in boys' and girls' timing and tempo of puberty: modeling development with nonlinear growth models

Pubertal development is a nonlinear process progressing from prepubescent beginnings through biological, physical, and psychological changes to full sexual maturity. To tether theoretical concepts of puberty with sophisticated longitudinal, analytical models capable of articulating pubertal development more accurately, we used nonlinear mixed-effects models to describe both the timing and tempo of pubertal development in the sample of 364 White boys and 373 White girls measured across 6 years as part of the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development. Individual differences in timing and tempo were extracted with models of logistic growth. Differential relations emerged for how boys' and girls' timing and tempo of development were related to physical characteristics (body mass index, height, and weight) and psychological outcomes (internalizing problems, externalizing problems, and risky sexual behavior). Timing and tempo are associated in boys but not girls. Pubertal timing and tempo are particularly important for predicting psychological outcomes in girls but only sparsely related to boys' psychological outcomes. Results highlight the importance of considering the nonlinear nature of puberty and expand the repertoire of possibilities for examining important aspects of how and when pubertal processes contribute to development.     

Brief report--associations of personality disorder with early separation anxiety in patients with adult separation anxiety disorder

A recent study has suggested a link between early separation anxiety and personality disorder. It is possible that this relationship is mediated or confounded by the presence of adult separation anxiety disorder (ASAD). In a clinic study of 397 anxiety patients, we found that ASAD patients with heightened early separation anxiety had higher rates of any Cluster C personality disorder compared to ASAD patients without elevated early separation anxiety, and higher rates of any Cluster B or C personality disorder compared to anxiety patients with low early separation anxiety and no ASAD. Although cross-sectional in design, the study supports a direct link between early separation anxiety and some adult personality disorders, irrespective of the type of adult anxiety disorder present, including ASAD.     

Aussagen ??ber traumatische Erlebnisse

The manner in which traumatic events are processed and recalled remains highly controversial. A central issue in the debate is whether traumatic experiences affect memory differently than other events. In this paper, two lines of research are reviewed: (a) comparisons of characteristics of traumatic and other memories and (b) comparisons of characteristics of traumatic memories of trauma survivors with and without posttraumatic stress disorder (PTSD). While PTSD groups reported more intrusive memories than non-PTSD groups, there is no consistent evidence for memory fragmentation neither for traumatic events in general nor for PTSD patients. Implications for credibility assessments are discussed.     

Who Wants these Stories? Reflections on Ethical Implications of the Re-publication of a Missionary Work

This paper discusses ethics in the context of Aboriginal Studies. Taking the example of a late-nineteenth century missionary work, a collection of out-of-print Mi’kmaq stories, it examines the ethical implications of the potential re-publication of such a text. It is argued that the Baptist missionary Silas T. Rand, who translated and transcribed the narratives, did his work from a Eurocentric perspective. The biases of a colonial ideology built into his translations/interpretations which are often quoted as authoritative would be further perpetuated if his work is republished without critical commentary. As Aboriginal oral traditions generally form the basis of Aboriginal cultures and contemporary Aboriginal literatures but have been demeaned for centuries thereby further colonizing the peoples, an edition of Rand’s work informed by a postcolonial ethics is crucial. The paper therefore concludes with the suggestion that the stories collected by the missionary should be repatriated in the respective Mi’kmaq communities in a way that the people can decide how to go about their publication (if they want them published at all). A non-Aboriginal scholar may facilitate the process but should follow the directions of the communities.
