The stability limits of erect stance are described as a geometrical structure in a movement space. Mechanical properties and response latency, a neural property, are determining factors for the stability limits. Standing stability limits of adults and young children are compared, and a simple scheme is suggested by means of which infants can discover the stability limits as they learn to stand. The mechanics of different standing movements are discussed because their spatial temporal properties relate directly to their different stability limits. The combination of the stability limits for different movements gives a total set of stability limits, a different structure for adults than for children. 相似文献
Objective: This study, which is part of a larger longitudinal study focusing on the biopsychosocial functioning of emerging adults with type 1 diabetes, examined how perceived personal control, coping and HbA1c relate to one another over time.
Design and main outcome measures: Emerging adults with type 1 diabetes (18–30 years old) participated in a two-wave longitudinal study spanning five years (N = 164 at Time 1). At both times, patients completed questionnaires on perceived control and coping (i.e. diabetes integration, avoidant coping and passive resignation). HbA1c values were obtained from treating clinicians. We investigated the directionality of effects using cross-lagged path analysis.
Results: Higher HbA1c values predicted relative decreases in diabetes integration and increases in avoidant coping five years later. Feeling less in control over diabetes predicted the use of passive coping over time. Passive coping predicted a relative decrease in perceived control five years later.
Conclusion: These findings indicate that tackling poor glycaemic control is not only important to avoid medical complications but also to prevent patients from resorting to more avoidant coping strategies. Furthermore, given the longitudinal interplay between perceived control and passive coping, it is important that intervention efforts include both cognitive and behavioural components to be effective. 相似文献
While economic downturns have adverse effects on young people's life chances, empirical studies examining whether and to what extent human values, social attitudes and well‐being indicators respond to sudden economic shocks are scarce. To assess the claim that human values are less affected by economic shocks than social attitudes and well‐being, two distinct yet related studies based on the European Social Survey (ESS) are conducted. The first employs a fixed effects pseudo‐panel analysis of the 2008–2014 ESS‐waves to detect whether changes over time in the socio‐demographic group's unemployment risk and national youth unemployment affect individual dispositions to varying degrees. The second study captures micro‐ and cross‐national effects in the 2010 ESS cross‐section. Unique for this set‐up is that we can test whether the findings hold for over‐time changes in youth unemployment within countries (pseudo‐panel), as well as for cross‐country differences in youth unemployment (multilevel). Both studies indicate that political trust, satisfaction with the economy and subjective well‐being are lowered by economic risk and hardship, while social trust and self‐rated health are less affected by changes in youth unemployment. Secondly, human values are immune to economic risk, underscoring that values transcend specific situations and are therefore resistant against sudden economic shocks. 相似文献

In this exploratory study, the neuropsychological and learning profile of nine primary school age children with velo-cardio-facial syndrome (VCFS) was studied by systematic neuropsychological testing. In five out of nine children, the following profile was found: a VIQ-PIQ discrepancy (in favor of the VIQ), significantly better scores (.05 level) for reading (decoding) and spelling compared to arithmetic, deficient tactile-perceptual skills (difficulties mainly on the left side of the body), weak but not deficient visual-perceptual abilities, deficient visual-spatial skills, extremely poor psychomotor skills (gross motor skills more deficient than fine motor skills), problems with processing of new and complex material, poor visual attention, good auditory memory and relatively good language skills. These findings correspond to the pattern of neuropsychological assets and deficits that has been described for the syndrome of nonverbal learning disabilities (NLD) (Rourke, 1987, 1988, 1989, 1995). The psychosocial profile of all nine children with VCFS also correspond to that of children with NLD. Further studies on the relationship between cognitive function, behavior, psychiatric disorder and abnormalities in brain anatomy in young people with VCFS will be needed. In clinical practice, it is worthwhile exploring in greater depth the neuropsychological functions of children with VCFS to rule out NLD, since they may benefit from specific remediation following the learning principles of the NLD-treatment. 相似文献
Adolescent dating violence is a pressing international issue: yet, there have been few attempts to collate the international evidence regarding this phenomenon. This article reviews contemporary evidence from Europe and North America on prevalence, dynamic risk factors, and the efficacy of intervention programs for adolescent dating violence. Prevalence findings suggest that victimization rates are comparable across Europe and North America. Although individual studies report differing prevalences, the overall hierarchy of violence types – in which psychological/emotional violence is most and sexual violence least prevalent – is consistent across almost all investigations. Four dynamic risk factors for perpetration are identified: peer influence, substance use, psychological adjustment and competencies, and attitudes towards violence. Peer influences and attitudes towards violence appear to be the most extensively evidenced factors in the literature. Nine existing intervention programs are identified, all located within North America. Intervention results are mixed, with some evaluations reporting significant long-term benefits while others report positive intervention effects dissipate throughout follow-up. Tentative analysis suggests that programs focused on behavioral change may elicit sustainable effects more readily. However, this is difficult to ascertain with no data on program repetitions and variations across intervention pedagogy and sample. Concerns with existing research and interventions and possible future directions are discussed. 相似文献
