采用纵贯研究、内容分析、深度访谈相结合的定性研究方法,以推动我国物联网产业发展的3个宏观政策决策过程为研究对象,旨在讨论政企互动是如何帮助政府进行不确定性管理的.研究结论表明:新兴产业的宏观政策决策是由数个存在递进关系的渐进式阶段组成,而每个渐进式事项的解决依赖于众多在政企互动中形成的微观政策工具的实施.政企互动帮助政策决策者通过4种机制(信息获取、行动协调、企业行动承诺和政府政策承诺)实现了对因信息缺乏以及对产业行动者资源依赖所造成的不确定性的管理.  相似文献

Among the many analytical techniques that have been published to analyze the significance of the effects in the absence of replications, two have emerged as the most widely used in text books as well as statistical software packages: The Lenth's method and the estimation of the variance of the effects from the values of those considered negligible. This article shows that neither is better than the other in all cases, and by analyzing the results obtained in a wide variety of situations it provides guidelines on when it is preferable to use one or the other technique.  相似文献

We derive explicit formulas for Sobol's sensitivity indices (SSIs) under the generalized linear models (GLMs) with independent or multivariate normal inputs. We argue that the main-effect SSIs provide a powerful tool for variable selection under GLMs with identity links under polynomial regressions. We also show via examples that the SSI-based variable selection results are similar to the ones obtained by the random forest algorithm but without the computational burden of data permutation. Finally, applying our results to the problem of gene network discovery, we identify through the SSI analysis of a public microarray dataset several novel higher-order gene–gene interactions missed out by the more standard inference methods. The relevant functions for SSI analysis derived here under GLMs with identity, log, and logit links are implemented and made available in the R package Sobol sensitivity.  相似文献

The authors examined how mothers' and fathers' feelings of competition at home and work affect their relationships with their daughters and sons using time‐diary data from a national sample of 220 families. Multivariate analyses revealed 3 relationships between parents' feelings of competitiveness at work and home and feelings of competition experienced by their children at school and home: (a) parents' and adolescents' competitiveness varied across home, work, and school—with mothers and fathers reporting similar levels of competition at work but daughters feeling more competitive at school than sons; (b) parents' competition at work was associated with similar activities; however, daughters' and sons' competition at school varied by activities; and (c) mothers' competition was associated with strategies for college enrollment and varied by gender, most notably with respect to daughters' academic progress. The results suggest how parents' competitive disposition may motivate their children's academic performance, especially between working mothers and their daughters.  相似文献

Social capital is a crucial factor for expatriates to employ as they cope with the demands of an international assignment. This longitudinal study used a mixed method approach to examine the social support benefits of expatriate contact with a local host. Western expatriates in the Netherlands were randomly divided into two groups: an experimental group (n = 33), that had contact with a Dutch host during 9 months, and a control group (n = 32) with no host. Qualitative methods such as interviews and diaries were included to shed light on the various types of social support that occurred. Results show that local hosts offered all four types of social support: social companionship, informational support, emotional support, and instrumental support. Furthermore, expatriates with a host increased their social capital; they received significantly more social support from host nationals than did those without a host. This study shows that HRD professionals may develop the social capital of expatriates by bringing them into contact with a local host, which can produce more social support from host nationals. Increased social capital may lead to a higher performance at both the individual and organisational levels.  相似文献

This article responds to calls to better understand how intersecting “inequality regimes” operate in organizations. Through in‐depth interviews with 25 white trans women about their workplace experiences, my analyses highlight how trans women navigate relational practices that are simultaneously gendered and cisgendered—that is, practices that maintain cultural connections between sex and gender and maintain gender as immutable. Findings demarcate three distinct mechanisms by which cisgenderism, a system that devalues women and trans people, operates and strengthens hierarchical privileges at work: (1) double‐bind constraints; (2) fluid biases of cissexism and sexism; and (3) group practices of privilege and subordination. In the first regard, analyses reveal unique double binds that trans women face—binds that dictate contradictory feminine and masculine ideal worker expectations but also expectations of gender authenticity. Second, I find that trans women often hover between two subordinate statuses (i.e., gender and transgender status) in a given workday, a fact that prods a more fluid conception of cisgenderism. Finally, this study highlights how cis men collectively mobilize through group practices to repair cisgender system breaches. All three dimensions are critical for understanding the production of workplace inequality between not only trans women and cis men, but all feminine‐identified workers.  相似文献

This paper investigates the role played by the smartphone for the quality of social interactions and subjective well-being. We argue that, due to its intrusiveness, the smartphone reduces the quality of face-to-face interactions and, as a consequence, their positive impact on well-being. We test this hypothesis in a large and representative sample of Italian individuals. The results indicate that time spent with friends is worth less, in terms of life satisfaction, for individuals who use the smartphone. This finding is robust to the use of instrumental variables estimation to deal with possible endogeneity. We also show that, consistent with our hypothesis, the positive association between time spent with friends and satisfaction with friends is less strong for individuals who use the smartphone.  相似文献

Given the gendered power relations and the isolated nature of women hotel room attendants' working environments, guest‐initiated sexual harassment experienced by room attendants is a significant, under‐investigated problem. This study of women attendants' experiences of sexual harassment was conducted in 5‐star hotels located on the Gold Coast — a notable tourism destination — of Queensland, Australia. Adopting a socialist–feminist critical theory epistemological perspective, the study used a qualitative constructivist grounded theory methodology. The research reveals the pervasiveness of sexual harassment experienced by women hotel room attendants. In particular, this study illuminates the varied forms, meanings and consequences of sexual harassment in a particular organizational context. In focusing on the interacting effects of the gendered nature of the hotel workplace and the hotel workplace culture, the near‐complete ‘normalization’ of sexual harassment within the hotels is revealed. This outcome is a source of considerable concern, with implications for the industry, for employment relations institutions and for public policy.  相似文献

Improving animal welfare is an important part of the development of the agricultural industry, particularly at a time when intensification and the encroachment of factory-style production systems is making the maintenance of human-animal relations increasingly difficult. Animal science deals with the issue of improving stockmanship by focusing on the relationships between attitudes and behaviour, under the premise that improved attitudes will lead to improved behaviour. From an analysis of 42 interviews with owners, sharemilkers and workers on dairy farms in New Zealand we present a different view, seeing behaviour instead as part of a self-reinforcing culture in which animals, humans and the physical structure all contribute to the development of farm specific ways of doing and being. We further suggest that changing one stockperson's attitude alone is insufficient to ensure a change in the culture as other actors – including animals and non-human actors – reinforce any existing culture that has developed, making both attitudinal and behavioural change difficult. We conclude by discussing the key importance of designing farm systems and structures that promote positive interactions between animals and humans and suggest that this, rather than simply promoting knowledge and attitudinal change, is likely to be the most effective way of maintaining stockmanship in the face of an industrialising agriculture.  相似文献
