基于市盈率、预期和供求关系的股价行为动态分析模型

针对现有股票价格模型的局限性,提出一个基于市盈率、预期及供求关系的股票价格行为动态分析模型。本模型考察市盈率、预期对股票市场供求关系的影响,探讨股票价格行为与投资者对公司未来每股收益的预期之间的关系,分析现行市盈率及动态市盈率与投资者普遍认可的合理市盈率之间的偏差对上述关系的影响,得出股票价格是在投资者对公司未来每股收益不断预期和矫正,以及对现行市盈率、动态市盈率与他们认可的合理市盈率之间偏差的不断判断和调整的基础上和由此导致的供求力量的作用下,围绕市场普遍认可的合理市盈率而上下波动的结论。     

Stretching the borders: how international business travel affects the work–family balance

This study examined the consequences of international business travel for the balance between work–family domains by exploring how international business travellers and travellers’ partners manage the boundaries between work and family in order to maintain the balance. Interpretative phenomenological analysis was used in analysing the semi-structured interviews of 10 male travellers and 10 partners. Because of its irregular nature, international business travel affects the personal life and the family of business travellers. Work-related travel also has an impact on how travellers and their partners construct, manage and negotiate borders between work and family in order to avoid an imbalance between these domains. Integration of work and family is usually inevitable in international business traveler families. Integration may lead to role blurring and thus lead to imbalance.     

Poking a sleeping bear: the challenge of organizational recruitment for controversial topics

ABSTRACT

Researchers often approach employers to investigate employees’ work and family experiences. Organizational willingness to grant access to employees can vary, especially when the research topic is seen as controversial or contentious for the employer. This paper explores this methodological challenge using a research example from Manitoba, Canada, which explored the use of parental leave by male employees and the impact of managerial attitudes and corporate culture on usage. Sixty large employers were recruited with only seven of those organizations agreeing to participate. In this paper, the reasons organizations gave for declining to participate and the implications of their decisions for the research are examined. Although the final sample included 905 managers and employees, participating organizations tended to be employee-focused and family-friendly employers. Organizations declined participation for a variety of reasons: avoiding raising the issue with unions, awareness that their policies unfairly benefited female leave takers, and simply not seeing the relevance of a topic relating to men’s work–family experiences. A dialogue often absent from the literature, it is important to understand how employers can limit researchers’ access to employees on controversial topics. The existence of such barriers suggests alternative avenues to recruit participants directly when topics are contentious for employers.     

‘The house belongs to both’: undoing the gendered division of housework

This article studies 28 dual-income Spanish childless couples who were undoing gender in routine domestic work. We understand ‘undoing gender’ as defined by Deutsch [(2007). Undoing gender. Gender & Society, 21, 106–127, p. 122]: ‘social interactions that reduce gender difference’. The dual-earner couples came from different socio-economic backgrounds and were interviewed in four different Spanish towns in 2011. The analysis shows that resources in a wide sense, time availability, external help, ideas about fairness, and complex gender attitudes are key interdependent factors that can weave together to form different configurations leading to a non-mainstream division of housework. All configurations were based on principles of gender equality: some couples found it fair to have a 50/50 division of domestic work, others a 50/50 division of all work (paid and unpaid); and a third group showed conflicts in practice. These couples’ ways of undoing gender illustrate the external, individual, and couple circumstances under which spouses are able to achieve a non-traditional construction of unpaid work.     

The ‘digital glimpse’ as imagining home

This paper proposes the concept of the ‘digital glimpse’, which develops the existing framing of imaginative travel. Here it articulates the experiences of mobile workers digitally connecting into family life and everyday rituals when physically absent with work. The recent embedding of digital communication technologies into personal relationships and family life is reconfiguring how absence is experienced and practiced by workers on the move, and through this, new digital paradigms for life on-the-move are emerging. This paper explores how such social relationships are maintained at-a-distance through digital technology – using evidence from qualitative interviews with mobile workers and their families. Digital technology now enables expressive forms of ‘virtual travel’, including video calling, picture sharing, and instant messaging. This has implications for the ways in which families can manage the social and relational pressures of being apart. Experiences of imaginative travel created through novel media can enrich the experience and give a greater sense of connection for both those who are at home and those who are away. While technology is limited in its ability to replicate a sense of co-presence, ‘digital glimpses’ are an emergent set of sociotechnical practices that can reduce the negative impact of absence on family relationships.     

中国地方政府债务问题探讨

中国地方政府债务问题形成的主要原因,一是政府过多地、直接地参与经济活动,二是城市化加速导致地方政府举债。对于中国地方政府债务问题,总体判断仍为风险可控。一是地方政府加上中央政府的债务占GDP的比例在40%以内,远低于60%的债务率标准。二是中央政府有非常强的控制能力,在各级政府间平衡债权债务,使得中国加总的净债务率较低。三是中国整体的资产负债表仍然健康,尤其是中央政府保持相当健康的资产负债表。对地方政府债务问题,体制性的解决办法是治本之道。要从根本上解决中国地方政府不规范借债问题,须建立规范化的地方政府举债融资机制。     

Dynamics of Domestic Labor Across Short‐ and Long‐Distance Family Relocations

Family relocations within developed countries are argued to have gendered consequences for paid employment, with men's careers improving and women's careers deteriorating. However, little is known about their potential relationships with outcomes in other life domains, including partnered men's and women's relative shares of domestic labor. The authors addressed this gap in knowledge by theorizing and examining how within‐couple gender gaps in domestic work evolve across short‐ and long‐distance family relocations over the life course, paying attention to the over‐time dynamics before and after event occurrence. To accomplish this, they used 12 years of panel data from the Household, Income and Labour Dynamics in Australia Survey and panel regression models. The results indicated that family relocations widen the within‐couple gender gap in weekly housework hours, largely because of shifts in women's employment situation and fertility episodes that accompany residential relocations.     

Parents' Family Time and Work Schedules: The Split‐Shift Schedule in Spain

This study used data on couples from the 2003 Spanish Time Use Survey (N = 1,416) to analyze how work schedules are associated with family, couple, parent–child, and non‐family leisure activities. Spain is clearly an interesting case for the institutionalized split‐shift schedule, a long lunch break rooted in the traditional siesta that splits the workday between morning and evening. Results showed strong negative associations between the split shift and both family and parent–child activities. The evening shift was negatively associated with couple and family time, but not with parent–child time. Women spent much more time than men in parent–child activities for all work categories, and they were more responsive to the spouse's work hours. Men were substantially more active than women in non‐family leisure, considering both individuals' and their spouses' work schedules. Altogether, this study has important implications for scientific and public policy debates.     

The Subjectivity of Fairness: Managerial Discretion and Work–Life Balance

We use organizational justice theory to examine how perceptions of fairness affect the decision‐making process of line managers. In‐depth interviews were conducted with 35 Irish managers to explore how managers make organizational allocation decisions in cases where it is impractical to offer work–life balance accommodations to all employees. The findings suggest that firstly, managers construct the ‘life’ aspect of work–life balance within a heteronormative framework, where the emphasis is on caregiving and most usually parenting. Secondly, managers actively use their decision‐making powers around both formal and informal work–life balance supports to minimize injustice within their departments. By bringing together ideas about organizational justice and managerial decision‐making, we indicate how managers determine fairness through a decision‐making process narrowed by embedded gender role beliefs. Implications for future research and practice are discussed.
