Exploration and Firm Performance: The Moderating Impact of Competitive Strategy

In this study we examine the moderating effect of competitive strategy (including differentiation and cost‐leadership strategies) on the relationship between exploration and firm performance. We find that the moderating effect of differentiation strategy is positive while that of cost‐leadership strategy is negative. And, these moderating effects are stronger in a highly competitive context. This study offers an explanation for previous mixed findings on the linkage of exploration to firm performance and enriches the discipline's knowledge regarding the performance implications of exploration. Moreover, we respond directly to the appeal in research on competitive strategy to clarify the role played by competitive strategy in profiting from exploration.     

Online MapReduce scheduling problem of minimizing the makespan

MapReduce system is a popular big data processing framework, and the performance of it is closely related to the efficiency of the centralized scheduler. In practice, the centralized scheduler often has little information in advance, which means each job may be known only after being released. In this paper, hence, we consider the online MapReduce scheduling problem of minimizing the makespan, where jobs are released over time. Both preemptive and non-preemptive version of the problem are considered. In addition, we assume that reduce tasks cannot be parallelized because they are often complex and hard to be decomposed. For the non-preemptive version, we prove the lower bound is \(\frac{m+m(\Psi (m)-\Psi (k))}{k+m(\Psi (m)-\Psi (k))}\), higher than the basic online machine scheduling problem, where k is the root of the equation \(k=\big \lfloor {\frac{m-k}{1+\Psi (m)-\Psi (k)}+1 }\big \rfloor \) and m is the quantity of machines. Then we devise an \((2-\frac{1}{m})\)-competitive online algorithm called MF-LPT (Map First-Longest Processing Time) based on the LPT. For the preemptive version, we present a 1-competitive algorithm for two machines.     

Reconfigured Reciprocity: How Aging Taiwanese Immigrants Transform Cultural Logics of Elder Care

Drawing on 55 interviews with older Taiwanese immigrants who relocated to the United States at an earlier life stage, the author argues that changing contextual features involved in the processes of international migration encourage and even demand aging immigrants to reconstruct cultural logics of aging and geriatric care. He develops the concept of reconfigured reciprocity to demonstrate how aging migrant populations transform cultural logics of intergenerational responsibility, obligation, and entitlement to reconcile the tension between ethnic tradition and modernity. First, he reveals how many of the respondents' lack of caregiving for their own parents undermines their sense of entitlement to receive care from younger generations. Furthermore, he highlights how the structural squeeze among work, family, and caregiving with which the younger generation struggles further discourages the respondents from relying on their children. Finally, the author underscores how aging immigrants evoke the concept of Americanization to reconstruct expectations of how they should be taken care of in their twilight years.     

论大学教学中的文化意识与文化自觉

“90后”大学生思政课教学新思路探析——以宁夏师范学院为例

＂90后＂大学生群体具有坚定的政治信仰、强烈的爱国热情、明确的价值取向;生活态度总体上积极健康,人生目标明确。但是由于各方面原因,这一群体对未来充满了不确定感,紧张、压抑、焦虑的情绪比较严重,如果不能妥善引导和疏通,情况堪忧。高校思政理论课在解决这些问题上发挥着重要作用。因此,思政课应从构建和谐师生关系和创新教学方法等方面,提高其教学实效性。     

智库影响力的国际比较与走向判断

现代智库已经成为各国决策者处理各种社会复杂问题所倚重的重要力量。中国与西方国家智库因为所处的体制环境不同,在独立属性上呈现出本土化运作的特征。通过对中西方智库的独立性的比较、分析和考察,以我国特有的国情为发展的起点,借鉴西方发达国家智库发展的成功经验,找到一条适合我国本土体制和国情的独立性的发展路径,是今后提高我国智库决策影响力的重要价值选择,也是促进我国决策科学化和民主化的重要动力。     

Influence of Temporal Distance on the Perceived Importance of Career‐Related Self‐Efficacy and Outcome Expectations

Because all career choices are about future actions, time is an important contextual variable in social cognitive career choice ( Hesketh, 2000 ). However, there is a dearth of research examining the effect of time. The authors examined how temporal distance to career entry influences the perceived importance of self‐efficacy and outcome expectations concerning a career pursuit. They also examined the moderating effects of perceived support and barriers, as well as country. The participants were college students in the United States (n= 180) and in South Korea (n= 215). The results of hierarchical regression analyses did not show main effects of time, but a 3‐way interaction indicated the complex interplay of time and other contextual variables. Implications for career counseling and future research are discussed.     

“微全球化”现象与中国青年

由于计算机网络等通讯媒体的广泛使用以及经济的全球化,人们的社会交往模式发生了革命性的变化,即突破国家的界限,形成了以个体为核心的全球性的社会交往模式。“微全球化”研究是一种基于微观视野的全球化研究．其一般模式和共同特点是把个人层面上涉及跨国界和跨文化的行为、交往、关系等方面的变化作为其研究的切入点,并进而把握某种跨国界和跨文化的行为、交往、关系。“微全球化”现象泛见于与青年群体相关的各种活动和事件中,对青年的发展具有积极的推动作用。     

Using naturalistic driving films as a design tool for investigating driver requirements in HMI design for ADAS

In recent years, there are many naturalistic driving projects have been conducted, such as the 100-Car Project (Naturalistic Driving study in United State), EuroFOT(European Large-Scale Field Operational Tests on Vehicle Systems), SeMi- FOT(Sweden Michigan Naturalistic Field Operational Test and etc. However, those valuable naturalistic driving data hasn't been applied into Human-machine Interaction (HMI) design for Advanced Driver Assistance Systems (ADAS), a good HMI design for ADAS requires a deep understanding of drive environment and the interactions between the driving car and other road users in different situations. The results demonstrated the benefits of using naturalistic driving films as a mean for enhancing focus group discussion for better understanding driver's needs and traffic environment constraints. It provided an efficient tool for designers to have inside knowledge about drive and the needs for information presentation; The recommendations for how to apply this method is discussed in the paper.
