需求率受推广努力水平影响的新能源汽车租赁系统协调契约

考虑由新能源汽车租赁企业和政府组成的二级系统，在需求率为随机且与推广努力水平相关的市场环境下，建立了新能源汽车租赁企业和政府之间的博弈模型，探讨了分散决策、集中决策、收益共享与成本共担契约下的最优车队配置和推广努力水平，并对三种情形下的最优决策进行了比较和分析。研究结果表明：在分散决策情况下无法实现系统协调，通过引入成本共担与收益共享组合契约，当契约参数满足一定条件时，该组合契约模型不仅可以实现系统协调而且可以使系统成员达到帕累托改进。最后通过算例分析，验证了模型了可靠性和有效性。     

女性"隐形"地位的多元认知透视

在男性占主导地位的语言,诚如英汉语中"乞丐""医生"等职业术语和"chairman""hero"等官衔荣誉称呼之类的名词,一般性的人类泛指"a man","mankind"以及代词的非指示用法中,女性往往被置于"隐形"的地位。性别差异和性别歧视的现象已引起社会上各学科的普遍关注,然而,从认知角度对这一现象作出注解的文章寥寥。运用认知语言学中的原型和范畴理论、框架理论、心理空间和概念合成理论对此予以阐释,可为英汉语中这一现象的理论阐释提供全新的多元认知视角。     

The effects of social and political openness on the welfare state in 18 OECD countries

Studies examining the relationship between globalisation and the welfare state tend to focus on the effects of economic dimensions of globalisation, the extent to which a country is part of the world market. Globalisation also has social and political dimensions and the effects of these on welfare states – in terms of social security transfers and generosity – are studied in this article. Data from the KOF Index of Globalisation , the OECD Historical Statistics and the Comparative Welfare Entitlements Dataset are used to analyse the effects of social and political openness on the welfare states of 18 countries of the Organisation for Economic Cooperation and Development between 1970 and 2000. The analyses show that social security transfers and generosity have increased less in countries with the highest increase in social openness and that the welfare state is not affected by political openness.     

自致努力、政府扶持与水电工程移民生计资本累积

基于2019年三峡库区移民生计专题调查数据,采用OLS、PSM以及分位数回归模型比较分析了移民生计资本的变化以及自致努力与政府扶持对移民生计资本的影响效应。研究发现：三峡水电工程移民搬迁显著减少了移民生计资本,且对外迁安置移民生计资本的负向影响比就地安置移民更大;自致努力与政府扶持均能显著增加移民生计资本,但政府扶持对移民生计资本的回报率显著低于就近安置地原居民,自致努力对生计资本的回报率在移民与就近安置地原居民中没有显著差异,该结论没有受到安置方式的影响;进一步研究还发现,随着生计资本分位点的提高,自致努力和政府扶持对移民生计资本的提升效应呈现递增趋势,这会扩大移民之间的生计资本差距。据此提出依据不同参照群体完善移民生计资本恢复和发展的评价制度,建立自致努力与政府扶持相结合的移民生计资本培育路径,同时加快缩小移民内部群体间生计资本差距等建议。     

销售商的努力影响需求变化的供应链的合约

本文首先重新考察报童模型,认识设计使供应链达到合作的合约的内在机制。在此基础上,提出一个设计供应链合约的一般模型,然后利用此模型分析在销售商的努力影响需求变化的情形下使供应链达到合作的合约的设计框架,同时提出一个在销售商的努力影响需求变化的情形下使供应链达到合作的合约。     

Communicating Conservation Status: How Different Statistical Assessment Criteria Affect Perceptions of Extinction Risk

Although alternative forms of statistical and verbal information are routinely used to convey species’ extinction risk to policymakers and the public, little is known about their effects on audience information processing and risk perceptions. To address this gap in literature, we report on an experiment that was designed to explore how perceptions of extinction risk differ as a function of five different assessment benchmarks (Criteria A–E) used by scientists to classify species within IUCN Red List risk levels (e.g., Critically Endangered, Vulnerable), as well as the role of key individual differences in these effects (e.g., rational and experiential thinking styles, environmental concern). Despite their normative equivalence within the IUCN classification system, results revealed divergent effects of specific assessment criteria: on average, describing extinction risk in terms of proportional population decline over time (Criterion A) and number of remaining individuals (Criterion D) evoked the highest level of perceived risk, whereas the single‐event probability of a species becoming extinct (Criterion E) engendered the least perceived risk. Furthermore, participants scoring high in rationality (analytic thinking) were less prone to exhibit these biases compared to those low in rationality. Our findings suggest that despite their equivalence in the eyes of scientific experts, IUCN criteria are indeed capable of engendering different levels of risk perception among lay audiences, effects that carry direct and important implications for those tasked with communicating about conservation status to diverse publics.     

Piety over Protest: Cognitive Liberation and Deflected Collective Action in Central India

Cognitive liberation is often treated in the social movements literature as a mediating factor through which political opportunities and mobilizing structures generate protest. This paper unpacks multiple dimensions of cognitive liberation and finds that they may operate in tension with one another. Building on scholarship that focuses on subjective factors in social movements, the paper examines the case of the Korku, an oppressed indigenous community in central India, who choose not to protest despite the presence of several dimensions of cognitive liberation. Rather than engage in collective political action, the Korku’s grievances are deflected toward depoliticized religious goals. The Korku seek communal improvement through Hindu piety in a context of the Hindutva cultural-nationalist ideology, rather than protest against the encroachment of this ideology on their community.     

Managing C-suite conflict: The unique impact of internal and external governance interfaces on top management team reflexivity

The ability of Top Management Teams (TMTs) to reflect critically on their own actions represents an important element of effective TMT decision making and governance effectiveness. This paper therefore examines how the TMT-board interface internal to the organization, as well as the TMT interface with the external supervisory authority, shape TMT reflexivity. Drawing from governance and psychological theories, we posit that cognitive conflict at the TMT-board interface can escalate by increasing levels of affective TMT-board conflict, and hereby, harm TMT reflexivity if not managed well. This proposition was tested in a multisource team-level data set collected in the field among TMTs (N = 111 TMT members) and their supervisory boards (N = 152 board members) of 56 Dutch insurance companies. The findings demonstrate that the link between cognitive and affective TMT-board conflict is mitigated by board membership influx. Yet in cases where conflict escalation does occur, its subsequent impact on TMT reflexivity hinges on the degree to which an external supervisory authority monitored TMT actions. The results illustrate that TMT decision making processes can be effectively influenced by internal and external TMT-governance interfaces, yet at different conflict stages, and through different governance actions.     

Institutional voids,international learning effort and internationalization of emerging market new ventures

Much of the existing scholarly works portray institutional voids (IVs) in emerging economies as impeding forces against the development of new ventures. However, little attention has been paid to how such voids generate positive outcomes in emerging market new ventures. Drawing on the institutional theory, we propose IVs as crucial enablers of new venture internationalization. In addition, we investigate both how and when IVs enhance the degree to which new ventures internationalize by examining international learning effort (ILE) as a mediator and two domestic market environmental factors (i.e., environmental dynamism and competitive intensity) as important contingencies. We test our moderated mediation model using primary data gathered from 211 new ventures from Ghana. We found that ILE mediates the relationship between IVs and new venture internationalization and that both environmental dynamism and competitive intensity moderate the indirect relationship between home-country IVs and new venture internationalization. We discuss the theoretical and practical implications of this study.
