The impact of career websites: what's the evidence?

ABSTRACT

Careers provision for young people in the UK is being re-formulated on the basis of a central role for career websites but this policy is based on unproven assumptions about their value. In this article we consider the use and impact of the two main career websites in Scotland on pupils' career management skills. We found that pupils at risk of not achieving positive post-school destinations were less likely to use the websites, as were minority ethnic pupils. Although similar in functions, the two websites differed in their effect: one had no impact while the other impacted on only one aspect of pupils' career management skills. Careers policy needs to be informed by more extensive research on career websites.     

Is It What You Do,or When You Do It? The Roles of Contingency and Similarity in Pro‐Social Effects of Imitation

Being imitated has a wide range of pro‐social effects, but it is not clear how these effects are mediated. Naturalistic studies of the effects of being imitated have not established whether pro‐social outcomes are due to the similarity and/or the contingency between the movements performed by the actor and those of the imitator. Similarity is often assumed to be the active ingredient, but we hypothesized that contingency might also be important, as it produces positive affect in infants and can be detected by phylogenetically ancient mechanisms of associative learning. We manipulated similarity and contingency between performed and observed actions in a computerized task. Similarity had no positive effects; however, contingency resulted in greater enjoyment of the task, reported closeness to others, and helping behavior. These results suggest that the pro‐social effects of being imitated may rely on associative mechanisms.     

环境雌激素双酚A对成年小鼠学习记忆和突触结构的影响*

双酚A (bisphenol, BPA)是一种广泛存在的环境内分泌干扰物,它可与雌激素受体结合干扰内源性雌激素对中枢神经系统的调控作用。本研究通过将10周龄小鼠灌胃染毒BPA (0.4、4、40 mg/kg/day)3个月,研究长期BPA暴露对成年小鼠记忆行为和突触可塑性的影响。开场行为测试结果表明, BPA (0.4、4、40 mg/kg/day)增加雄性的站立次数和理毛频率, BPA (4 mg/kg/day)却显著减少雌鼠的站立次数。水迷宫和被动回避行为模型检测显示, BPA主要损伤雄鼠的空间学习记忆和被动回避记忆。通过制备海马CA1区超薄切片后,电镜观测发现, BPA (0.4、40 mg/kg/day)暴露降低雄鼠海马CA1区突触数密度,缩短雄鼠突触前活性带长度,减小雄鼠突触后致密体(PSD)厚度,增加雄鼠突触间隙宽度。进一步用Western blot方法检测突触前、后的标志性蛋白Synapsin I和PSD95以及兴奋性氨基酸NMDA受体NR1亚基和AMPA受体GluR1亚基蛋白的表达,发现BPA暴露致雄鼠Synapsin I、PSD95、NR1蛋白表达水平下调。而BPA对雌鼠的记忆行为、突触形态、突触蛋白和受体蛋白均没有明显作用。以上结果提示长期B PA暴露性别特异性地影响成年小鼠的活动性和探究行为,损伤雄鼠的学习记忆,这些作用可能通过下调突触蛋白和NMDA受体的表达而负性影响突触结构可塑性,最终影响雄鼠的学习记忆功能。     

DIVINE PURPOSE AND EVOLUTIONARY PROCESSES

When Darwin's theory of natural selection threatened to put Paley's Designer out of a job, one response was to reemploy God as the author of the evolutionary process itself. This idea requires an account of how God might be understood to act in biological history. I approach this question in two stages: first, by considering God's action as creator of the world as a whole, and second, by exploring the idea of particular divine action in the course of evolution. As creator ex nihilo God acts directly in every event as its sustaining ground. Because God structures the world as a lawful order of natural causes, God also acts indirectly by means of creatures. More controversially, God might act directly within the world to affect the course of events; this action need not take the form of a miraculous intervention, if the natural order includes the right sort of indeterministic chance. In each of these ways God's purposes can shape evolutionary processes.     

Factors influencing infants’ ability to update object representations in memory

Remembering persisting objects over occlusion is critical to representing a stable environment. Infants remember hidden objects at multiple locations and can update their representation of a hidden array when an object is added or subtracted. However, the factors influencing these updating abilities have received little systematic exploration. Here we examined the flexibility of infants’ ability to update object representations. We tested 11-month-olds in a looking-time task in which objects were added to or subtracted from two hidden arrays. Across five experiments, infants successfully updated their representations of hidden arrays when the updating occurred successively at one array before beginning at the other. But when updating required alternating between two arrays, infants failed. However, simply connecting the two arrays with a thin strip of foam-core led infants to succeed. Our results suggest that infants’ construal of an event strongly affects their ability to update memory representations of hidden objects. When construing an event as containing multiple updates to the same array, infants succeed, but when construing the event as requiring the revisiting and updating of previously attended arrays, infants fail.     

Negotiating safer sex: A detailed analysis of attitude functions,anticipated emotions,relationship status and gender

Objective : Because interpersonal discussion about condom use can encourage subsequent condom use, this project aims to examine the psychological antecedents of intentions to discuss or request the use of condoms with a sexual partner.

Method : The data were collected from 849 heterosexual college students in the USA through an online survey. The survey contained several measures related to attitude functions (i.e. motivations), efficacy, norms and intentions to discuss condom use with a sexual partner.

Results : Participants’ attitude functions weakly predicted intentions to discuss condom use. Communication efficacy was a more important predictor of intentions for females (vs. males) and for those in other relationships or not in a relationship (vs. long-term monogamous relationships). Anticipated negative emotions were a stronger predictor of intentions for those in long-term monogamous relationships (vs. other relationships or not in a relationship).

Implications : Future research needs to consider more detailed attitude functions and anticipated emotions. Furthermore, background variables (e.g. gender and relationship status) can be moderators in addition to being distal predictors.     

Engagement with meditation as a positive health trajectory: Divergent narratives of progress in male meditators

Objective: Studying personal narratives can generate understanding of how people experience physical and mental illness. However, few studies have explored narratives of engagement in health positive behaviours, with none focusing on men specifically. Thus, we sought to examine men’s experiences of their efforts to engage in and maintain healthy behaviours, focusing on meditation as an example of such behaviour.

Design: We recruited 30 male meditators, using principles of maximum variation sampling, and conducted two in-depth interviews with each, separated by a year. Main outcome measures: We sought to elicit men’s narratives of their experiences of trying to maintain a meditation practice.

Results: We identified an overall theme of a ‘positive health trajectory,’ in particular, making ‘progress’ through meditation. Under this were six main accounts. Only two articulated a ‘positive’ message about progress: Climbing a hierarchy of practitioners, and progress catalysed in other areas of life. The other four reflected the difficulties around progress: Progress being undermined by illness; disappointment with progress; progress ‘forgotten’ (superseded by other concerns); and progress re-conceptualised due to other priorities.

Conclusion: Men’s narratives reveal the way they experience and construct their engagement with meditation – as an example of health behaviour – in terms of progress.     

Psychology,health and health care

This article traces the development of the World Health Organization's emphasis on psychological and behavioural factors in health and notes its encouragement of recognition of these factors by member states. The article further outlines the reasons for this increasing recognition and stresses the important role of psychological and behavioural factors in the maintenance of health and prevention of illness.     

Being and feeling liked by others: How social inclusion impacts health

This study examined the effects of perceived and actual social inclusion on health across and within individuals from a network perspective. During the first semester, 75 freshmen students provided bi-weekly ratings on their perceived social inclusion and health. To capture actual social inclusion, each student nominated liked and disliked fellow students. Perceived social inclusion mediated the effect of actual social inclusion on health. Specifically, students with more ‘likes’ perceived more social inclusion and those with higher perceived inclusion reported a better health status (between-person effect). In addition, at time points, when students received more ‘likes’ they also perceived more social inclusion. They reported better health at times when they felt more included (within-person effect). Thus, the perception of social inclusion is rooted in reality and actual social inclusion has an impact on health when passing the filter of perception.
