劳动合同自由与劳动合同正义浅探

劳动合同正义是劳动合同自由的核心,一部劳动合同自由的发展史,同样也是劳动合同正义的演进史。劳动合同消极自由与劳动合同形式正义、劳动合同积极自由与劳动合同实质正义的理论与实践表明：劳动合同积极自由与劳动合同消极自由相互包容,以此来达到劳雇双方利益的均衡,进而达到社会和国家利益的均衡时,劳动合同的形式正义与实质正义也就得到统一,劳动合同正义也就得以实现,劳动合同自由与劳动合同正义的动态的协调统一也就得以完成。

＂新医保＂在农村的顺利实施对我国进一步纵深发展,构建和谐社会,都大有裨益。在西部各省启动新型农村社会养老保险试点的大背景下,对农村＂新医保＂实施之背景进行梳理分析,选取四川两村村民对当前＂新医保＂认知程度及接受能力等方便的问卷调查分析,提前认识＂新医保＂推行中将遭遇的困难,并提出相关对策,以期为今后西部农村＂新医保＂之推行提供相关政策制定指引,实现＂新医保＂推行之未来学探索。     

民族主义与韩国外交政策

民族主义作为一种情感归属和价值诉求,大多兴起于社会转型与断裂时期,以其模糊性赢得了广阔的生存空间,其黏合性彰显了巨大的工具价值.现代化推动了当前韩国民族主义的兴起与发展,其主要采取宣扬民族文化优越性、寻求历史荣光与付诸现实政策等建构方式.其间,经过诸多危机事件的碰撞,韩国民族主义逐渐形成了从民族情感到民族意识形态的广泛领域,在现实政策中不断得以强化,并通过对外交决策机制的介入、社会氛围的营造、意识形态的塑造等深刻影响着韩国外交政策.

浅谈高等学校按类招生及人才培养

按类招生是一种新的招生和人才培养模式,是高等学校深化教育教学改革的一项重要措施,体现了“以人为本”的教育理念,对培养具有创造能力、应变能力的高素质复合型人才方面,无疑具有其极大的优势,但是,作为一种新的培养模式,同样也存在许多问题。招生方式的改革只是表面的东西,更重要的是教育体制的革新。     

An approximation algorithm for maximum internal spanning tree

Given a graph G, the maximum internal spanning tree problem (MIST for short) asks for computing a spanning tree T of G such that the number of internal vertices in T is maximized. MIST has possible applications in the design of cost-efficient communication networks and water supply networks and hence has been extensively studied in the literature. MIST is NP-hard and hence a number of polynomial-time approximation algorithms have been designed for MIST in the literature. The previously best polynomial-time approximation algorithm for MIST achieves a ratio of \(\frac{3}{4}\). In this paper, we first design a simpler algorithm that achieves the same ratio and the same time complexity as the previous best. We then refine the algorithm into a new approximation algorithm that achieves a better ratio (namely, \(\frac{13}{17}\)) with the same time complexity. Our new algorithm explores much deeper structure of the problem than the previous best. The discovered structure may be used to design even better approximation or parameterized algorithms for the problem in the future.     

Workplace adversity and resilience in public relations: Accounting for the lived experiences of public relations practitioners

Public relations practitioners face workplace challenges as they cultivate public relationships, resolve conflicts, and manage crises. Odds of adversities may be high in this role, requiring practitioners to be resilient. This qualitative study explores workplace adversities in public relations from a practitioners’ perspective, and examines how they enact resilience. By asking current practitioners about their lived experiences, we found workplace adversities occurred on multiple levels and ranged from mundane to life-altering events. Patterns of resilience were, metaphorically, bouncing forward, bouncing up, bouncing back, and bouncing around. This study contributes to public relations and resilience scholarship by (1) uncovering workplace adversities and resilience enactment in public relations, therefore connecting practice with scholarship, (2) extending the “bounce back” metaphor in the resilience literature, therefore making resilience more inclusive, and (3) exploring the connections of multi-level resilience, and suggesting the complex and negotiated nature of resilience among individuals embedded in collectives.     

Online amplification of air pollution risk perception: the moderating role of affect in information

This study investigates the amplification effect of the Internet on Chinese people’s air pollution risk perception. Analyses are based on data collected from a sample of Internet users in Beijing, Shanghai, and Guangzhou (N?=?328). This study assumes that the characteristics of online information ? availability of information and affect in information ? will significantly contribute to the increase in air pollution risk perception. Results of path analysis indicated marginal significance of the effect of information availability on air pollution risk perception. Regarding the influence of affect in information, results showed that information including appeals to affect significantly increased perceived risk of air pollution; meanwhile, it also functioned as a moderator that significantly increased the strength of the causal relationship between information availability and risk perception. Findings of this study suggest that strategies for appropriately amplifying risk perception such as using heuristics may contribute to promoting public awareness of risks as well as encouraging public participation in the social effort to tackle risks.     

Grandparenting and support from adult children: Does children’s international migration make a difference for Chinese older adults?

ABSTRACT

Guided by social exchange theory, this study investigates the association between grandparenting and support from adult children, and the role of children’s international migration in moderating such association. Data were derived from a 2012 survey of older adults in Beijing, China (478 adult children nested in 300 older parents). The results of independent cluster logistic and linear regressions showed that regardless of children’s migration status, grandparenting was significantly associated with a greater likelihood of receiving household help and personal care, but not with emotional or financial support from children. Children’s migration status moderated the associations between grandparenting and receiving support from children. Theoretical implications for research and practical implications for services and policies are discussed.     

Exposure to news about the South China Sea,nationalism, and government evaluation: examining the mediation roles of third-person effects and online discussion

Based on the communication mediation model, the third-person effect hypothesis was integrated to analyze the influence of the exposure to South China Sea news on its perceived effects on the self and others. In addition, the influences of such exposure on online discussions and political attitudes were examined, specifically in relation to nationalism and government evaluation. The survey (N?=?868) found that the respondents perceived a stronger media effect on others than on themselves, whereas exposure to traditional and news media exposure exhibited equivalent effects on the self and on others. Moreover, the perceived effects on oneself promoted online discussion and nationalism, whereas the perceived effects on others improved government evaluation. The findings of this study indicate that the effects of media exposure on nationalism and government evaluation are marginally mediated by perceived effects, online discussion, or both.
