Friendship stability and change in childhood and adolescence

The objective of this review is to focus on a neglected aspect of children’s and adolescents’ friendships: the level of temporal stability. First, a rationale for examining stability as a distinct friendship dimension is presented. Next, the different levels of friendship experiences are distinguished. Friendship stability is also discussed across developmental periods. Factors affecting friendships stability and individual correlates associated with friendship stability are then covered. Finally, the methodological issues pertaining to the study of friendship stability are addressed. The authors conclude by emphasizing the importance of pursuing future research that aims to demonstrate the pertinence of the friendship stability construct as an individual difference variable. Further, on a methodological level, the assessment of stability needs to be based on longitudinal designs that include multiple measurement waves. Ultimately, such detailed analysis of stability will allow a better understanding of the dynamic processes by which friendships change over time and affect children’s and adolescents’ psychosocial development.     

An order of pure decision: growing up in a virtual world and the adolescent's experience of being-in-a-body

Technological advances and the dominant values of contemporary culture make it possible and acceptable to alter, extend, or altogether bypass the body and its functions in actuality and in virtual space. This has contributed to a split between the body and the self, leading to a disembodied subjectivity that may encourage a neglect of the body's unconscious meaning for the individual. Due to the psychic requirement during adolescence to accommodate the reality of the changing body, some vulnerable adolescents are especially primed for the seductions of virtual space--a "space" that is nowadays not only culturally sanctioned, but also idealized. The use of cyberspace can become a psychic refuge from the challenge of integrating the reality and meaning of the sexual body into the image of the self. Two case examples illustrate how for some vulnerable adolescents it is through the use of cyberspace that confusion about the real body can be denied or disavowed; for them the integrity of the self is sustained through pseudorepresentations of the body defensively experienced in terms of "play" rather than pathology.     

Beliefs about age-related changes in physical functioning across the adult life span and their relationship with physical activity levels of older adults

Physical activity declines across the adult life span despite the well-established links between physical activity and health-related, psychological, cognitive, and social benefits. We contrasted the beliefs young and older adults hold about how aging affects both physical abilities and physical activity and determined whether older adults’ beliefs about physical aging relate to their engagement in physical activity. Using visual rating scales, 56 young and 49 community-dwelling older adults indicated the extent to which a typical woman or typical man aged 20–90 possesses six different physical abilities and engages in three different types of physical activity. Stereotypes of physical aging were ability- and activity-specific, and older adults endorsed more positive views than their younger peers. Stereotypical beliefs predicted older adults’ engagement in moderate-intensity activity. This study offers intriguing avenues for future research and suggests that better understanding physical aging stereotypes may contribute toward designing interventions that promote lifelong physical activity.     

Self-projection in middle childhood: a study on the relationship between theory of mind and episodic future thinking

Cognitive Processing - Growing evidence suggests that theory of mind (ToM) and episodic future thinking (EFT) are closely related at both brain and functional level. This study explored the...     

“Not at All Religious”: Irreligiosity as Social Deviance in a Majority Muslim Context

In a majority Muslim context, where most college students are raised religiously and appear outwardly to conform to social norms in terms of dress and religious ritual, which college students are most likely to report that, in fact, they consider themselves “Not At All Religious”? When irreligiosity is treated as a measure of social deviance, does Hirschi’s theory of social control appropriately account for this demographic? I use original Islamic Social Attitudes Survey data collected from 1,139 Kuwaiti college students in 2007 to show that gender, being raised religiously, and religious experience are all significantly correlated to irreligiosity. Neither family attachment nor peer networks predicts self-reported irreligiosity like the influence of conservative Mosque Networks.     

“Nanostandardization” in Action: Implementing Standardization Processes in a Multidisciplinary Nanoparticle-Based Research and Development Project

Nanomaterials have attracted much interest in the medical field and related applications as their distinct properties in the nanorange enable new and improved diagnosis and therapies. Owing to these properties and their potential interactions with the human body and the environment, the impact of nanomaterials on humans and their potential toxicity have been regarded a very significant issue. Consequently, nanomaterials are the subject of a wide range of cutting-edge research efforts in the medical and related fields to thoroughly probe their potential beneficial utilizations and their more negative effects. We posit that the lack of standardization in the field is a serious shortcoming as it has led to the establishment of methods and results that do not ensure sufficient consistency and thus in our view can possibly result in research outputs that are not as robust as they should be. The main aim of this article is to present how NanoDiaRA, a large FP7 European multidisciplinary project that seeks to investigate and develop nanotechnology-based diagnostic systems, has developed and implemented robust, standardized methods to support research practices involving the engineering and manipulation of nanomaterials. First, to contextualize this research, an overview of the measures defined by different regulatory bodies concerning nanosafety is presented. Although these authorities have been very active in the past several years, many questions remain unanswered in our view. Second, a number of national and international projects that attempted to ensure more reliable exchanges of methods and results are discussed. However, the frequent lack of publication of procedures and protocols in research can often be a hindrance for sharing those good practices. Subsequently, the efforts made through NanoDiaRA to introduce standardized methods and techniques to support the development and utilization of nanomaterials are discussed in depth. A series of semi-structured interviews were conducted with the partners of this project, and the interviews were analyzed thematically to highlight the determined efforts of the researchers to standardize their methods. Finally, some recommendations are made toward the setting up of well-defined methods to support the high-quality work of collaborative nanoparticle-based research and development projects and to enhance standardization processes.
