关于20世纪中外文学关系研究的梳理与思考

作为一门跨学科研究,20世纪中外文学关系的研究与比较文学、中国现当代文学的学科发展密切相关.该研究方向在发展初期吸收了影响研究的思路和方法,在原始资料的搜集、整理,以及20世纪中外文学的交流和比较研究等方面,取得了相当的成绩,同时也面临着新的挑战,研究者们对影响研究的质疑、关于"20世纪中国文学中的世界性因素"的提出、对"文学性的重申"等,都是试图使20世纪中国文学能以对等的姿态进入世界文学的多元格局中,并以自己的独特创造丰富世界文学,20世纪中外文学关系研究也将在不断的质疑与尝试中,寻求自身的突破与发展.     

大面积建成区建筑密度遥感制图产品的精度验证

大面积建成区建筑密度遥感制图产品能够提供土地开发强度与人类居住环境的基础信息,是支撑人居环境研究和土地利用规划的重要数据。全球人类居住区层（global human settlement layer,GHSL）是由欧盟联合研究中心负责的大面积人居环境制图项目,建成区建筑密度遥感制图产品是GHSL重要的组成部分。目前该产品在欧美地区已经完成了GHSL建成区建筑密度遥感制图产品的验证。然而以中国为代表的东亚区域的建筑物形态和城市布局与欧美等区域有较大的差别,有必要在亚洲地区对其进一步验证。以中国的5个典型城市（上海、西安、长春、昆明和乌鲁木齐）大面积单体建筑物分布图为基础,通过聚合分析和邻域关键点搜寻匹配等算法,生成中国建成区建筑密度栅格图像产品作为验证数据,然后通过回归分析等方法,在像元尺度上对GHSL建成区遥感制图产品进行评价验证。结果显示,GHSL建成区建筑密度产品在较低分辨率下可以反映中国地区建筑密度情况,但在较高分辨率下在高值区过高估计密度。本研究可以为中国地区研发建成区建筑面积密度产品提供依据。     

Leveraging microgrants to support capacity-building workshops in low- and middle-income countries for meeting the Sustainable Development Goals

Twenty fifteen marked the year of assessment for the Millennium Development Goals (MDGs). The MDGs that achieved the greatest success were those where evidence-based practice (EBP) interventions were implemented. The ability to practice evidence-based medicine is grounded in the creation of and access to medical literature that synthesizes research findings. The role that global health literature played in the success of the MDGs demonstrates that medical libraries and librarians have a role to play in achieving the Sustainable Development Goals (SDGs).Librarians can hold capacity-building workshops that provide instruction on how to access evidence-based literature and also train health professionals to conduct synthesis research. Research findings conducted by in-country health professionals are more likely to address issues being faced by local communities and will afford the possibility of obtaining the necessary evidence-based answers that can then be used to implement policies to resolve public health issues identified in the SDGs.This paper discusses how an international team of librarians leveraged funding from a Medical Library Association/Librarians without Borders/Elsevier Foundation/Research4Life grant to hold a capacity-building workshop in Zimbabwe and follow-up online trainings. The workshop focused on accessing evidence-based resources and conducting synthesis research. Outcomes included the creation and policy implementation of evidence-based knowledge products in alignment with local needs and galvanizing a multisectoral group of key individuals who have gone on to collaborate toward the vision of creating a Zimbabwe innovation hub. Looking ahead, such grants can be leveraged to conduct capacity-building to support knowledge translation and other local training needs.

我国体育用品制造业国际转移的趋势及动力机制——基于全球生产网络视角

我国体育用品制造业国际转移呈现出网络化、多元化、集群化、主动化的新趋势,其动力来源有三点,一是寻求我国体育用品制造业价值链的重构,二是试图跨越后发国家可能面临的价值链固化的"网络陷阱",三是追逐包括竞争优势和网络权力等隐形收益在内的综合利益最大化。但是,这种自觉行动和主动作为可能受到价值链上端发达国家的阻击。因此,我国体育用品制造业要利用研发设计和品牌营销价值链的发育突破门限效应,积极开展跨境并购和逆向投资活动弥补比较劣势,并逐步回归到研发本土化,利用国内中小体育用品企业构建由自己主导的价值链,以全球布局应对潜在的贸易风险。     

Postural balance and rifle stability in a standing shooting position after specific physical effort in biathletes

The aim of the study was to evaluate the effect of maximal specific physical effort on postural balance and rifle stability in biathletes in a standing shooting position. The study included 10 junior elite biathletes. The measurements were taken with the Vicon system and AMTI force platform. Postural balance and rifle stability characteristics were determined at rest as well as 1 and 5 min post maximal specific physical effort which was performed on a ski ergometer and continued until exhaustion. Maximal physical effort exerted a significant effect on all examined postural sway and rifle sway characteristics. The duration of the post-exercise changes was longer than 5 minutes. Higher post-effort rifle sway was observed in the vertical direction than in the across the shooting line direction. Post-effort postural balance impairment in the shooting line was much greater than in the across the shooting line direction. Moreover, a strong correlation was found between postural balance and rifle stability. Maximal physical effort influenced postural balance and rifle stability during aiming. Rifle sway during aiming in a standing shooting position seems to be coordinated with the postural sway of the biathlete’s body. Thus, an increase in postural sway contributes to greater sway and lesser stability of the rifle.

乒乓球运动员以预防损伤为主的功能训练

功能训练的理念来源于康复领域,现已逐步应用到运动训练中。由于乒乓球运动的项目特征,乒乓球运动员肩关节、腰椎关节、膝关节、踝关节、腕关节等部位容易出现运动损伤。通过对乒乓球运动员常出现的功能问题进行分析,寻找存在的常见问题,进而提出相应的功能训练建议。乒乓球运动员可根据情况,增加改善肩关节、胸椎关节、髋关节、踝关节的活动范围的训练,提高肩胛骨、核心和下肢稳定性的训练,以及改善肩袖、躯干肌力不平衡的训练,通过针对性的功能训练有效减少乒乓球运动员损伤的发生。     

石膏/蚯蚓粪肥对赤泥团聚体结构稳定性的影响

赤泥是氧化铝工业生产过程中排放的高碱性固体废弃物,迄今尚无经济有效的处置方法。以华中地区某堆场赤泥为研究对象,通过土培实验研究改良剂（石膏、蚯蚓粪肥、石膏+蚯蚓粪肥）对赤泥团聚体稳定性的影响。结果表明：石膏的添加能显著降低赤泥pH,而蚯蚓粪肥能显著增加赤泥有机碳含量。土培60 d时,石膏添加后赤泥pH由10.54降到8.75,蚯蚓粪肥添加后赤泥有机碳含量由3.54 g·kg^-1增加至14.31 g·kg^-1。土培180 d时,石膏、蚯蚓粪肥、石膏+蚯蚓粪肥添加后赤泥水稳性团聚体含量由12.04%分别增加到23.49%、29.24%、33.94%;团聚体平均重量直径由0.15 mm分别增加到0.26、0.30、0.34 mm;可蚀性因子由0.36分别降低到0.31、0.30、0.29。石膏和蚯蚓粪肥的添加促进水稳性团聚体形成,提高赤泥团聚体稳定性。基质改良对赤泥团聚体稳定性的影响效果依次为：石膏+蚯蚓粪肥 > 蚯蚓粪肥 > 石膏。研究结果对赤泥土壤化处置和规模化消纳研究有科学参考意义。
