  • Post‐publication peer review (PPPR) has not achieved its promise and potential.
  • Few articles receive PPPR – even those in high‐profile journals.
  • PPPR is difficult to find and needs to be linked to the original article.
  • Academics require recognition if they are to contribute their time to PPPR.
  • Improving PPPR would improve the scholarly corpus.

摘要:运动缺乏症(EDD)是一种儿科疾病,特点是中高强度体力活动(MVPA)下降,低于目前的推荐量,也与积极的健康结果(health outcomes)不一致。目前,大多数儿童和青少年符合EDD的诊断标准,因为他们没有达到日常MVPA的最低要求。本文的目的是强调10个与青少年EDD有关的重要研究问题。需要进行重要的研究来更好的定义EDD的临床表现,包括评估体力活动行以确定开始出现EDD的年龄或发育阶段;包括运动技巧和体能的运动起源(kinesiogenesis)的检测;以及对影响青少年MVPA的生活方式因素的评估。关于治疗EDD的干预措施和政策的研究问题,包括评估对卫生保健从业者进行运动医学重要性的教育和训练;确定在临床上识别和治疗EDD青少年的方法的有效性;开发敏感的、特效的、经济的方法以诊断青少年EDD;以及定制方法以促进本病诊疗的医疗保险赔付。如果未来研究不能优化EDD青少年的识别、治疗和管理方案,具有重大影响的生物医学、心理、经济和政治的新的卫生保健问题将会不断出现。  相似文献

Purpose:

The purpose of this lecture is to challenge librarians in clinical settings to leverage the opportunities presented by the current health care environment and to develop collaborative relationships with health care practitioners to provide relevant services.

Discussion:

Health care organizations are under financial and regulatory pressures, and many hospital librarians have been downsized or have had their positions eliminated. The lecture briefly reviews hospital librarians'' roles in the past but focuses primarily on our current challenges. This environment requires librarians to be opportunity focused and pivot to a new vision that directs their actions. Many librarians are already doing this, and colleagues are encouraging us to embrace these opportunities. Evidence from publications, websites, discussion lists, personal communications, and the author''s experience is explored.

Conclusion:

Developing interdisciplinary and collaborative relationships in our institutions and providing relevant services will mark our progress as vital, contributing members of our health care organizations.  相似文献

Although research suggests that there is no meaningful real-world connection between crime rates and undocumented immigrants, media coverage of this group almost exclusively portrays them as criminals. The present two-study investigation experimentally tests the effects of exposure to crime news depicting undocumented immigrant suspects on White viewers’ social judgments. To this end, assumptions from social identity theory were applied to research and theorizing on mediated intergroup threat and compound penalties for immigrant criminality. Results from Study 1 and Study 2 indicate that when White viewers are exposed to threatening crime news featuring undocumented immigrants, out-group bias emerges in the form of harsher sentencing. In Study 1, when exposed to highly threatening coverage, attitudes toward immigration and in-group identification partially mediated and moderated this relationship, respectively.  相似文献

Insecure attachment and behavioral inhibition (BI) increase risk for internalizing problems, but few longitudinal studies have examined their interaction in predicting adolescent anxiety. This study included 165 adolescents (ages 14–17 years) selected based on their reactivity to novelty at 4 months. Infant attachment was assessed with the Strange Situation. Multimethod BI assessments were conducted across childhood. Adolescents and their parents independently reported on anxiety. The interaction of attachment and BI significantly predicted adolescent anxiety symptoms, such that BI and anxiety were only associated among adolescents with histories of insecure attachment. Exploratory analyses revealed that this effect was driven by insecure‐resistant attachment and that the association between BI and social anxiety was significant only for insecure males. Clinical implications are discussed.  相似文献
