基于价值主张与动态能力互动的企业资源配置案例研究

在消费升级的大环境下,价值主张精确地传达产品的价值优势并指导资源的有效配置,能够促使企业通过优化配置资源更好地满足市场需求以获取竞争地位。采用扎根理论的研究方法透过企业资源配置现象的典型案例构建理论框架,剖析价值主张与动态能力的互动对资源配置的影响机理及其演进过程。研究表明：（1）在不同情境因素的诱发下,价值主张与动态能力快速互动调整达到相适配,进而保证价值主张的有效性并促使能力发挥到极致以完成预期目标;（2）企业依据价值主张提炼出合理的资源配置决策,并由与价值主张相匹配的动态能力作为支柱性要素对资源进行改造利用,使资源配置在价值主张与动态能力的作用下表现为“简单拼凑式-探索开发式-协奏共享式”的演进过程。本研究结论对于企业如何通过清晰的价值主张进行有效资源配置以获取竞争优势有着重要理论和实践意义。     

基于辍学研究的电大课程教学反思——以“变化中的英语”课程为例

本文基于电大辍学归因研究中的学习负荷问题展开讨论。调查显示,学习负荷过高造成了许多电大学生在学习道路上的无功而返,而学习的高负荷是由课程难度与学生学术水平之间的落差所造成的。本研究旨在通过对电大课程教学过程的审视,探究其学术支持服务手段的有效性。本研究以2011年3-6月上海电大A分校2010春英语专业本科层次"变化中的英语"课程教学为个案,通过面授课堂观察、课程形成性考核记录、网上教学记录、课程期末考试成绩聚焦课程教学效果。研究结果显示,电大的课程教学支持服务手段仍停留于传统教学模式,而作为重要学习辅助手段的网上学习,其形式意义占据和弥漫于抽样所在班级师生的观念中,导致学习支持的可获得性受到制约;同时,由于任课教师在电大体制下被层层嵌于一个庞大的系统之中,教师的能动性在改善课程教学效果时会受到一定程度上的限制;第三,在多方原因的共同作用下,现行教学模式下学生的课业表现与预期课程教学目标之间存有潜在的些微差距,会在一定程度上影响任课教师对自身课程教学的判断和调整。改变这种状况,电大教学组织制度的变革和对教师支持服务力度的加强势在必行。     

“以大观小”与“以道观之”——论沈括式中国特色透视观与庄子观物态度之关联

沈括在《梦溪笔谈·书画》中提出的“以大观小”论,是中国特色透视观的经典言论之一,体现了庄子“以道观之”的观物态度。“以大观小”之“大”,正是“道”之大,只有“道”才具有小天下的大视野,才能穿越物我的藩篱,时空的界限,沟通物物的关系,建构起多向度、多层次的立体网状新视城;“以大观小”之“观”,融哲学思想、心灵观照与视觉现象于一炉,而不纯粹发生在视觉领域。沈括式透视观,是庄子“以道观之”的哲学思想在绘画领域的落实。     

不同处理条件对洋葱鳞茎表皮细胞骨架形态影响的研究

细胞骨架是活细胞的重要结构,研究细胞骨架的形态对于进一步研究其功能具有重要意义。本研究以洋葱为材料,设置了4个不同的1％Triton X-100抽提非骨架蛋白时间（10min、15min、25min、40min）对洋葱细胞骨架显微观察的关键条件进行了优化,同时分析了细胞环境温度（-18℃、4℃、20℃、50℃）,紫外线照射活细胞（0min、60min）,0．1mol／L Ca^2＋处理及0．1％秋水仙素处理对洋葱细胞骨架形态观察效果的影响。结果表明：1％Triton X-100抽提非骨架蛋白25min观察效果较好;-18℃、50℃,紫外线辐射60min,0．1mol／L Ca^2＋和秋水仙素处理均会影响细胞骨架的观察。

新型农村社区建设中居民社区参与的动力机制分析

新型农村社区居民在社区参与上主要存在参与内容具有明显选择偏好、参与行为具有区隔性以及参与意愿与实际参与行为不符等问题。通过建构利益驱动机制、认同驱动机制和制度驱动机制,帮助居民拓宽获取社会资本的渠道,增强居民社区认同感,搭建社区参与的制度平台,有助于增强社区居民的参与意识,改善社区居民参与状况。     

Acute effects of different warm-up protocols on highly skilled golfers’ drive performance

Previous research has highlighted the positive effect that different warm-up protocols have on golf performance (e.g. Sorbie et al., 2016; Tilley & Macfarlane, 2012) with the design of warm-ups and programmes targeting and improving golf performance through the activation and development of specific muscle groups. This study aimed to examine the acute effects of two warm-up protocols on golf drive performance in comparison to a control condition. Using a randomised counterbalanced design over three testing sessions, twenty-three highly skilled golfers completed the control, dynamic and resistance-band warm-up conditions. Following each condition, a GC2 launch monitor was used to record ball velocity and other launch parameters of ten shots hit with the participants’ own driver. A repeated-measures ANOVA found significant increases in ball velocity (η_p² = .217) between the control and both the dynamic and resistance-band warm-up conditions but no difference between these latter two, and a reduction in launch angle between control and dynamic conditions. The use of either a dynamic stretching or resistance-band warm-up can have acute benefits on ball velocity but golfers should liaise with a PGA Professional golf coach to effectively integrate this into their golf driving performance.     

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。     

The dynamic control ratio at the equilibrium point (DCRe): introducing relative and absolute reliability scores

Analytical methods to assess thigh muscle balance need to provide reliable data to allow meaningful interpretation. However, reproducibility of the dynamic control ratio at the equilibrium point has not been evaluated yet. Therefore, the aim of this study was to compare relative and absolute reliability indices of its angle and moment values with conventional and functional hamstring–quadriceps ratios. Furthermore, effects of familiarisation and angular velocity on reproducibility were analysed. A number of 33 male volunteers participated in 3 identical test sessions. Peak moments (PMs) were determined unilaterally during maximum concentric and eccentric knee flexion (prone) and extension (supine position) at 0.53, 1.57 and 2.62 rad · s^–1. A repeated measure, ANOVA, confirmed systematic bias. Intra-class correlation coefficients and standard errors of measurement indicated relative and absolute reliability. Correlation coefficients were averaged over respective factors and tested for significant differences. All balance scores showed comparable low-to-moderate relative (<0.8–0.9) and good absolute reliability (<10%). Relative reproducibility of dynamic control equilibrium parameters augmented with increasing angular velocity, but not with familiarisation. At 2.62 rad · s^–1, high (moment: 0.906) to moderate (angle: 0.833) relative reliability scores with accordingly high absolute indices (4.9% and 6.4%) became apparent. Thus, the dynamic control equilibrium is an equivalent method for the reliable assessment of thigh muscle balance.     

A knock to the system: A new sociotechnical systems approach to sport-related concussion

Broader contextual factors that influence concussion management have tended to be overlooked. To address this, the present study used a sociotechnical systems approach to identify perceived responsibilities and applied strategies for three domains of concussion management (i.e., prevention, identification and treatment). Participants were 118 members of the community rugby union system in Australia (69.2% male). Participants from throughout the rugby system (e.g., players, parents, coaches, club management) were asked open-ended questions about their perceived responsibilities and the strategies they use for concussion management. It was found that (a) proper training, technique correction and education were recurrent prevention themes; (b) the majority of key stakeholders felt that they could consistently identify concussion; however, medical aids (medics) were the only system actors who stated a responsibility to use standardised concussion assessment measures and (c) less than one third of the respondents indicated their involvement in treating concussion. This study identifies specific junctures in the system that prevents effective concussion management strategies. A sociotechnical systems approach improves the understanding of concussion prevention, and management beliefs and behaviours.
