Stereotype and National Attachment in Hong Kong Chinese Context: A Moderated Mediation Model of Perceived Inter-group Relationship and Age

The present study investigated the relationship between Hong Kong people’s stereotype toward Mainland people and their own national attachment (i.e., national identity, constructive patriotism, and uncritical patriotism). The role of inter-group relationship as mediator and age as moderator of that relationship were also tested. A total of 1753 local Hong Kong people aged 17–80 (mean age = 20.35 years, SD = 5.02) completed anonymous questionnaires regarding their stereotypes toward Mainland people, inter-group relationship with Mainland people, and national attachment. As expected, stereotypes toward Mainland people, inter-group relationship and national attachment showed significant positive associations with each other. More interestingly, it was found that the inter-group relationship mediated the relationship between stereotypes toward Mainland people and three domains of national attachment, with this indirect link being weaker for younger Hong Kong adults than for older Hong Kong adults. Implications of the present findings for future research are discussed, as well as potential interventions for increasing subjective national attachment to China, especially in young Hong Kong people.     

美国博物馆青少年教育工作探析

文章考察了美国博物馆的青少年教育的概况和具体形式,认为美国博物馆的青少年的开始时间早,教育形式不但多样,而且契合青少年的年龄特点,取得了较好的成效。我国博物馆的青少年教育在教育理念、形式做法、实际效果等方面都与美国博物馆存在着不小的差距,需要进一步向美国博物馆学习。     

自由与责任:网络空间伦理诉求及其实现策略

习近平在世界互联网大会上的主旨讲话中指出,互联网把世界变成了“鸡犬相闻”的地球村,改变着人们的生产生活,有力推动了社会发展;同时,他又指出,网络空间不是“法外之地”,并明确提出了加强网络空间治理、规范网络空间行为等要求.网络的虚拟性、开放性和交互性,既给人们提供了自由的空间和舞台,又对人们的道德要求和责任担当提出了更高的要求.行为主体网络信息的自由表达有其必要的边界和限度,网络行为中的责任担当对规范网络空间和现实社会的有序发展存在着积极的应然价值,自由与责任构建了网络空间最基本的伦理诉求.     

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.     

The reproductive health indices and sex hormone levels in middle-aged and elderly Chinese men

Objective: The aim of this study was to analyze the age-related recession trajectory of reproductive health indices in middle-aged and elderly Chinese men.

Methods: A population-based cross-sectional study was conducted in Jiashan County, Zhejiang in 2012. Healthy men between 40 and 80 years of age were considered eligible for the study. Physical examination and the sex hormones were measured. The subjects were assessed based on the 5-item version of the International Index of Erectile Function (IIEF-5) for Erectile Dysfunction (ED), and Aging Males’ Symptoms (AMS) scale for Symptomatic Late-Onset Hypogonadism (SLOH).

Results: TG showed a decrease at age 60 years. Testis volume and TT did not show significant difference among the four age groups; cFT began to decrease at age 50 years and Bio-T decreased faster at age 50 years. SHBG and LH increased faster at age 50 and 70 years, respectively. IIEF5 score decrease faster at age 60 years. AMS scores increased faster at age 70 years. With the increase in age, the symptoms of ED and SLOH became severer.

Conclusion: Different indices on reproductive health of men showed turning points at different ages. At first, androgenic sex hormones decreased faster, and then erectile dysfunction got severer, and the last overall male syndromes declined.     

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.
