Dancing is a performing art form whereby participants move their body in time to a rhythm (usually music). It is a physical activity that has been associated with improving fitness and physical wellbeing. An activity often enjoyed in childhood, it often falls away as we get older and relatively few people participate once they reach adulthood.
No lights, no lycra (NLNL)是一个全球社区,所有跳舞吗ows participants to indulge in free form dancing in the dark, providing a non-judgmental, inclusive and drug and alcohol free environment. It’s an activity that has gained popularity.
考虑到这一点，Foley等最近研究了参加这项活动的人。他们收集了有关其人口特征，体育活动水平，进行活动的动机以及NLNL对健康和福祉的影响的信息。
This investigation was performed via a self-report online survey where each participant was asked to describe their experiences and motivations. This revealed that NLNL mostly attracts adult women who, by and large, are not particularly fit and have not historically engaged in much organised physical activity before.
这说明了如何修改有组织的体育活动，以吸引本来不感兴趣的人群，并强调需要了解这种修改如何激励和维持通常不活动的人们的参与。
BMC卫生服务研究–在特定的移民压力下，支持欧洲国家的难民和移民获得医疗保健
2015年，欧盟国家（EU）的国家经历了超过一百万的难民和移民的涌入。所谓的难民危机。
This resulted in an increase in migratory pressures; providing care for the most vulnerable groups created some significant challenges. In essence, refugees and migrants frequently found themselves with no effective healthcare. As a response to this, a study was performed by Chiarenza and colleagues to inform the development of a “resource package”, aiming to improve such access. This involved conducting interviews and focus groups in order to collect up-to-date information on the challenges different healthcare provides faced in relation to the refugee crisis, as well as a literature review on barriers to healthcare access and possible solutions.
Researchers found that the barriers faced by refugees and migrants were due to challenges related to whether they had just arrived to a EU country, were in transit or whether they have reached their final destination. These challenges created, for example, legislative, financial and administrative barriers to healthcare, lack of reliable information on the health status of individuals, lack of knowledge of entitlements and what help was available, and lack of organization and co-ordination between different services. These issues were particularly acute when trying to access mental health, sexual health, child services or victim of violence care services.
研究结果表明，与开发的解决紧急情况的解决方案通常会创建一个既混乱又分散的系统，从而分散了欧盟卫生系统变化的需求，以防止弱势群体获得医疗保健。
BMC医学教育–The role of WhatsApp® in medical education; a scoping review and instructional design model
信息技术（IT）改变了我们交流方式的许多方面。反过来，这对教育产生了相当大的影响，例如，提供了多种多媒体学习资源的手段。然而，围绕是否有足够的证据支持使用IT工具进行医学教育的好处，特别是，特别是，医学教育学习的进步是否更多地由社会行为和廉价技术驱动，而不是改善结果的驱动。
Coleman and O’Conner recently performed a scoping review of a popular messaging and voice over IP service, WhatsApp, the aim of which being to see how it is used and evaluated as a tool in medical education. They performed two searches of the published literature, using the term “WhatsApp” as the search term. They discovered that WhatsApp was being used in implementing one of three different strategies – namely educational use with a pre-defined curriculum, educational use without a curriculum, or a primarily non-educational use.
有一些报道说，使用WhatsApp作为学习工具后，学习者知识有所改善，但是几乎没有证据表明正在使用任何学习理论。Coleman and O’Conner have taken the three strategies for WhatsApp use and developed their own model that draws on the Dabbagh and Bannan-Ritland’s exploration-enactment-evaluation learning design framework for online education, from which they propose their own instant messenger design model for medical education.
BMC Zoology–为碘钓鱼：Bonobos的水生觅食告诉我们有关人类进化的信息
脑发育，特别是脑组织的扩展和先进的认知能力的发展是人类进化的特征。它与促进这种发展的营养有关，包括碘。这种关键营养素的丰富来源主要在沿海地区找到。因此，这提出了一个问题，即大陆地区早期人类素如何满足其碘要求。
尝试回答这个问题的一种方法是研究当今的人类灵长类动物如何能够采购这些营养素。
Bonobos are only found in the central region of the Congo basin, an area considered to be somewhat iodine deficient.
Hohmann and colleagues measured the mineral content of the fruit, terrestrial and aquatic herbs in the area, which showed that it was the aquatic herbs that contained most iodine and, importantly, two species in particular had iodine concentrations almost equivalent to that found in marine algae. This challenges the assumption that the Congo basin is iodine deficient and shows that it offers natural sources of the nutrient in concentrations high enough to prevent iodine deficiency in hominoids and humans.
