Background: Athletes, coaches, sport psychology practitioners, and researchers suggest that mental toughness represents an important construct that is associated with athletic performance. Unfortunately, the absence of real-world performance as a dependent variable has limited our ability to substantiate this claim. The concern of a lack of ecologically valid measures of sports performance might be addressed by examining the relationship between mental toughness and sports performance using a standardized measure of personal best(PB) triathlon time and a validated unidimensional measure of mental ***: Three hundred and sixteen triathletes completed the 8-item mental toughness index(MTI), reported their age, and provided a PB Olympic distance triathlon time and the total number of triathlons they had completed to date. Given that males are typically quicker than females, a standardized time was calculated by dividing the PB by the current Olympic record for gender; we also hypothesized that more experienced triathletes would report quicker PB times because of greater frequency and duration of training. Once we had controlled for gender and experience,we predicted that mental toughness would be negatively associated with triathlon time and the size of the relationship would be of a moderate ***: Results revealed small-to moderate-sized negative relationships between both completed number of triathlons and mental toughness with standardized PB ***: The hierarchical regression analysis showed that mental toughness provided a unique contribution to the variability in standardized Olympic triathlon PB after controlling for the total number of triathlons completed.

The European Union （EU） Wild Birds Directive recognises that the most serious threats to wild birds＇ conservation in Europe are habitat loss and degradation, and hence, habitats of threatened and migratory species must be protected with the establishment of the network of the special protection areas （SPAs） for migratory and endangered bird species in the EU member states. The major European population of the lesser kestrel Falco naumanni, a migratory falcon listed in Annex I of the Birds Directive, occurs in low-input farming systems in the Mediterranean basin, including Greece. The aim of this study was to identify foraging habitats of lesser kestrels and relate them to the delimited SPAs in the agro-ecosystems of Greece, where the stronghold of the species population for Greece occurs. Foraging habitat preferences were assessed using Poisson regression models （PRMs）. SPAs were examined on whether they can effectively protect foraging habitats for breeding lesser kestrels in the study area. Foraging lesser kestrel abundance was positively associated with grasslands and non-irrigated land （dry cereals）, and negatively associated with irrigated land （wet cotton）, scrubland and woodland. Electricity facilities were used as foraging perches by lesser kestrels. The current SPAs cover a small percentage of the species＇ foraging sites and cannot be considered coherent enough to support and protect the foraging habitats of lesser kestrels and other priority species in the agro-ecosystems of the study area. Proposals for effective conservation of low-input farming systems, supporting priority species, are also presented.

本文关注世界各个地域如何在电影中思考时间意义上的现代性这一问题。作者从简要引介电影时间也即吉尔·德勒兹的时间-影像概念开始,并以巴西电影《我的美味法国小男人》(1971)为例展开重点分析。这部独特而精彩的电影以它的后殖民重要性为著称,它让我们去重新思考世界历史意义上的时间-影像之确切含义。麦尔克·哈尔特、安东尼奥·内格里和阿尼巴尔·奎加诺这样的哲学家,他们根据伊曼纽尔·沃勒斯坦的世界体系分析做出了一些研究结论,认为时间-影像表达了始于美洲被发现以来的五百年现代历史。本文并非仅仅要提供一个不同角度来思考时间-影像这一概念,而是试图阐释当代世界电影中显而易见的多种现代性电影时间,向非-欧洲中心电影哲学迈出第一步。

群体成员围坐在火塘周围和睦地分享食物,是人与动物的一个重要区别。也正是这种饮食文化以及隐含在其背后的社会行为,对全球的环境以及人类社会的进化历程产生了深远的影响。这种对于其他动物而言陌生而又颇有影响力的行为,究竟如何组成了人类生活的一部分?针对这一命题,人类学家们提出了不同的理论,比如本文介绍的马文·哈里斯、杰克·顾迪、玛丽·道格拉斯、克洛德·列维·斯特劳斯等人,对于这一过程中作为自然人和社会人都进行了深入剖析。这个命题同样也是历史学家和考古学家们关注的焦点之一。根据现有的文献和食物资料,我们究竟能对人类分享食物的历史做出什么样的判断?毋庸置疑,在这项研究中,考古资料发挥着至关重要的作用。任职于剑桥大学考古系的马丁·琼斯是世界著名的人类学家,长期致力于人类早期食物遗存的考古学研究。《宴飨的故事(Feast:Why Humans ShareFood)》是他凝聚几十年研究成果和心得汇集而成的专著。书中,作者借助于最新的科技考古手段,为我们重建了人类食物发展和饮食文化的历史——从黑猩猩分享猎物的场景到大学教授们参加的正式宴会,从罗马帝国的盛大酒宴到电视快餐,这每一种行为都是人类饮食历史中文化驱动力的结果。全书跨越五千万年的时空背景,栩栩如生地描绘了人类食物的历史以及食物对社会和地球生态系统的巨大影响。本文选译的是书中第一章,作者生动地贯穿了人类学家的理论和考古学家们目前所掌握的获取资料的各种手段,为后文详细展开人类分享食物的历史画面做了铺垫。文章深入浅出,娓娓道来,尽管介绍的是考古学的前沿课题,不过即便是不懂考古学的人也能读得津津有味,让读者在愉快的阅读中体会到考古学的魅力。(方辉)
