Associations Among Psychologically Controlling Parenting,Autonomy, Relatedness,and Problem Behaviors During Emerging Adulthood

The present study aimed to investigate the relations among perceived parental psychological control (PPC), autonomy and relatedness, and negative outcomes during emerging adulthood in two cultural contexts: Italy and the USA. More specifically, we explored the mechanisms through which dependency-oriented PPC (DPPC) and achievement-oriented PPC (APPC) are associated with both internalizing and externalizing difficulties, focusing on the mediating role of autonomy and relatedness. Participants were 418 European-American and 359 Italian college students. Results indicated that the expressions of PPC with regard to dependency and achievement were related to emerging adults’ negative outcomes through different pathways, and these effects were moderated by the cultural group. The implications of the findings for future related empirical investigations and clinical interventions were discussed.     

Expanding Perspectives on Evangelicalism: How Non-evangelical Students Appreciate Evangelical Christianity

Evangelical students pose a distinctive set of challenges to higher education professionals. These students, though advantaged to some degree because of their Christian identity, commonly report feeling marginalized and silenced on college campuses. In light of these tensions, the purpose of this study was to examine how non-evangelical students come to an appreciative understanding of evangelical Christianity. Specifically, the research focused on the specific campus conditions and experiences that influence non-evangelical students’ appreciative attitudes toward evangelicals. Findings reveal distinct demographic, institution type, and academic major differences in those students’ perspectives toward their evangelical peers. Additionally, the results suggest that appreciative attitudes toward evangelicals are associated with non-evangelical students’ interfaith experiences, albeit to differing degrees based on self-identified worldview. Recognizing that the work of helping non-evangelical students develop an appreciative understanding of evangelicals is as complicated as it is challenging, especially in the collegiate context, the authors conclude with a discussion of implications for research and practice.     

Fractal models for event-based and dynamical timers

Some recent papers proposed to distinguish between event-based and emergent timing. Event-based timing is conceived as prescribed by events produced by a central clock, and seems to be used in discrete tasks (e.g., finger tapping). Emergent or dynamical timing refers to the exploitation of the dynamical properties of effectors, and is typically used in continuous tasks (e.g., circle drawing). The analysis of period series suggested that both timing control processes possess fractal properties, characterized by self-similarity and long-range dependence. The aim of this article is to present two models that produce period series presenting the statistical properties previously evidenced in discrete and continuous rhythmic tasks. The first one is an adaptation of the classical activation/threshold models, including a plateau-like evolution of the threshold over time. The second one is a hybrid limit-cycle model, including a time-dependent linear stiffness parameter. Both models reproduced satisfactorily the spectral signatures of event-based and dynamical timing processes, respectively. The models also produced auto-correlation functions similar to those experimentally observed. Using ARFIMA modeling we show that these simulated series possess fractal properties. We suggest in conclusion some possible extensions of this modeling approach, to account for the effects of metronomic pacing, or to analyze bimanual coordination.     

Extending the technology acceptance model to mobile telecommunication innovation: The existence of network externalities

• Consumer acceptance of technological innovations is crucial to marketing new products. According to the most influential model in this area, the Technology Acceptance Model (TAM), perceived usefulness (PU) and perceived ease of use (PEOU) determine users' behavioural intentions to use or purchase a system or product. In the specific context of network externalities, a sense of utility that arises from the number of users (NOU) is considered as important as technology‐specific valuation. This study conducted an empirical survey to examine the effects of TAM and network externalities on the acceptance of Multimedia Messaging Services (MMS), an innovation in the field of mobile telecommunications. The results confirm the effectiveness of the TAM and find that network externalities effect affects users' acceptance to this mobile innovations. Accordingly, the TAM can be applied to predict consumer's acceptance to the mobile telecommunication innovations in the presence of network externalities.

Inexperienced newborn chicks use geometry to spontaneously reorient to an artificial social partner

A fundamental process underlying navigation behaviour, shown to occur in every species tested, uses geometric properties of the environment for location memory and orientation. Here we employ a new method to ask whether this basic geometric orientation ability is innately predisposed in the brain or depends on specific experiences navigating in a geometrically rich environment. Using the newborn domestic chick as a model system, we present a working memory task testing reorientation towards a filial imprinting object under rigorous controlled rearing conditions. In the absence of any previous exposure to a geometrically rich environment, newly hatched chicks spontaneously recovered their bearings by making use of distances and directional relations to reorient themselves to an artificial social partner. These findings provide evidence for an innate capacity to navigate by the geometric structure of the environment.     

Energy‐Related Behaviors in Office Buildings: A Qualitative Study on Individual and Organisational Determinants

An analysis of individual and organisational determinants of energy‐related behaviors in office buildings and the interplay between the two is presented. Interviews and focus groups were conducted with office workers from four organisations in two Dutch provinces. The results indicate that, overall, work efficiency and productivity was prioritised over energy conservation. In general, self‐efficacy was the most salient individual determinant, and social norm the least discussed determinant of current office energy‐related behaviors. Nevertheless, both self‐efficacy and social norm elements were encountered in employees' proposed strategies to achieve future office energy‐saving. Formal and informal aspects of the organisational context were found to equally affect individual determinants and their related behaviors. Facility managers' and general office workers' views differed in a few but important ways. Interorganisational comparisons showed that differences in organisational foci were linked to the relative salience of normative, gain, and hedonic motivations.

An Examination of the Role of Mentees’ Social Skills and Relationship Quality in a School-Based Mentoring Program

Research on youth mentoring highlights the importance of the relationship quality between mentor and mentee; mentoring results in more positive outcomes when the mentee perceives the relationship as satisfying and trustworthy. Research on relationship quality shows that social skills are important for constructing new relationships. However, whereas improved social skills are often one of the main goals of youth mentoring, little is known about the importance of social skills for relationship quality in youth mentoring relations. In this study, we examined whether mentee's pre-intervention social skills were related to mentor–mentee relationship quality as perceived by the mentee, and in turn, if relationship quality was associated with post-intervention social skills. We additionally examined possible gender and age differences in these associations. Data were used from a two-wave study that assessed relationship quality and social skills before and after one semester of mentoring of 390 secondary school students in a school-based mentoring program. Results indicated that relationship quality was positively associated with post-intervention social skills. However, only for young mentees pre-intervention social skills were associated with better relationship quality. Moreover, only for young mentees, relationship quality mediated the association between pre- and post-intervention social skills.
