七运会女子跳高冠军金铃伤后的恢复性训练

我校优秀女子跳高运动员金铃手术后恢复期间训练安排分三个阶段，突出速度和力量素质的训练，坚持大负荷量的训练，有针对性地进行技术练习，建立教练员和运动员互相信任的机制是金铃恢复训练提高成绩的关键。金铃成功的事例证明其赛前训练的安排是合理的，科学的，可行的。这一事例也为其同类情况的运动员提供了参考依据。     

优秀冰壶运动员专项心理能力研究

专项心理能力在冰壶运动中有着举足轻重的位置。近年对冰壶心理方面的研究尚停留在现象层面,在现象之下探析专项心理能力的主要内容是后续研究的关键。通过现场观察、专家访谈、逻辑分析,提出冰壶运动的专项心理能力主要是以构建心理稳定性为核心的能力建设,即专项认知能力、专项人格特征、情绪识别与控制、心理恢复能力等几个方面。在日常训练中加强心理建设,是培养良好专项心理能力、维护赛场心理稳定性的关键。     

围封对阿尔乡沙化区域生态恢复潜力综合评价

阿尔乡与内蒙古科左后旗相毗邻,是科尔沁沙地南缘的一部分。随着人类过度的放牧和不合理的土地利用,土地沙化现象愈演愈烈,围栏封育以其投资少,易实施的特点成为治理沙化现象的主要措施。本文以阿尔乡围封的沙化土地为研究区域,运用恢复生态学、植物生态学和土壤学等多学科理论,通过野外调查、室内试验及数据统计分析等多种手段,运用综合指数法对生态恢复潜力进行综合评价,证实了围栏封育对阿尔乡沙化区域的生态恢复效应显著,揭示了围栏封育对该区域生态恢复的潜力。

Accelerated matrix recovery via random projection based on inexact augmented Lagrange multiplier method

In this paper, a unified matrix recovery model was proposed for diverse corrupted matrices. Resulting from the separable structure of the proposed model, the convex optimization problem can be solved efficiently by adopting an inexact augmented Lagrange multiplier (IALM) method. Additionally, a random projection accelerated technique (IALM+RP) was adopted to improve the success rate. From the preliminary numerical comparisons, it was indicated that for the standard robust principal component analysis (PCA) problem, IALM+RP was at least two to six times faster than IALM with an insignificant reduction in accuracy; and for the outlier pursuit (OP) problem, IALM+RP was at least 6.9 times faster, even up to 8.3 times faster when the size of matrix was 2 000×2 000.     

深部回采巷道底臌锚杆支护研究

针对鸡西东海煤矿采深1160m条件下,巷道产生底臌现象的实际情况,对32号层五采区四段回风平巷,应用底板锚杆支护进行研究。结果表明,在原有巷道支护的基础上加打底锚能够有效地控制底臌和巷道两帮的移近量,减少巷道围岩的变形量,保证巷道的稳定性,从而保证生产的正常进行。     

助学贷款的不同目标--对贷款的设计、评价及政策可能产生的影响

本文对世界各地助学贷款的不同目标作了简要的回顾和评论 ,着重论述了两种不同目标取向的助学贷款之间的差异 :第一类助学贷款追求经济目标 ,如贷款的设立是为了促进高等教育的成本补偿 ,为紧张的大学财政获取额外财源 ;第二类助学贷款追求社会目标 ,如设立贷款的目的是为了增进高等教育入学机会均等 ,帮助更多贫困家庭的学生上大学。以经济目标为导向的助学贷款一般不含政府补贴 ,以社会目标为导向的助学贷款可能享受政府的补贴 ,但需要对贷款对象进行认真仔细的确认。文章最后指出 ,助学贷款的设计和评价必须考虑到贷款政策的目标。     

面向恢复的计算研究现状和发展

随着数字计算性能的提高,数子系统变得越来越复杂,运行变得脆弱且不可靠.如与计算机相关的故障变得司空见惯.面向恢复的计算(ROC)认为:硬件故障、软件故障以及操作员错误仍需要人们面对,但不必作为一定要彻底解决的问题.通过关注平均修复时间,而不是平均故障时间,发现快速的恢复减少了恢复时间,因而提供了更高的可用性.     

Business continuity of business models: Evaluating the resilience of business models for contingencies

Company business models are vulnerable to various contingencies in the business environment that may unexpectedly render their business logic ineffective. In particular, technological advancements, such as the Internet of things, big data, sharing economy and crowdsourcing, have enabled new forms of business models that can effectively and abruptly make traditional business models obsolete. By disrupting or even diminishing companies’ revenue streams, environmental contingencies may present a significant threat to business continuity (BC). Evaluating the resilience of business models against these contingencies should therefore be a core area of BC. However, existing BC approaches tend to focus on the continuity of the resources and processes through which a particular business model is accomplished in practice but omit the business model itself. We argue that in order for BC approaches to become holistic and strategic, business models need to become a part of the BC considerations, entailing an expansion of the scope of BC from value preservation to value creation. We propose an approach of Strategic Business Continuity Management, which consists of two parts: (1) sustaining the continuity of the company business model (value preservation) and (2) evaluating and modifying the business model (value creation). We illustrate conceptually the value creation part with an example drawn from the sharing economy.
