Impact of female-focused HRM practices on workplace outcomes in China
No full textBased on a survey of 227 employees in two organisations in China, this study examines the links between the female-focused human resource management(female-focused HRM) practices and workplace outcomes (job satisfaction and turnover intention). We found that female-focused HRM does not directly influence job satisfaction or turnover intention; instead, the impact is exerted through perceived organisation support. Interestingly, the women and men we surveyed both responded similarly when questioned on the importance of female-focused HRM.Findings from this study suggest that female-focused HRM is unlikely to be perceived as preferential treatment for female employees; instead, it is they are interpreted as an organisation’s support for employees who will likely reciprocate with a positive workplace attitude. This research advances our knowledge about the relationship between female-focused HRM and workplace outcomes in the East Asia context and disperses the myth of a negative perception of HRM policies by the non-users
What drives older people in China to work?
No full textChina is posited to become the country with the largest older population in the world with rising longevity and declining fertility. Its myriad retirement schemes and retirement age rules date back to the 1950s and are not suited to the fast-rising ageing population. Its myriad retirement schemes and retirement age rule traced back in the 1950s are struggling to cope with the fast-rising ageing population. There is limited understanding on what motivates people to work at an older age in China. This study examines how access to different types of pensions, human capital and economic factors influence the propensity of people aged 50 and above to work in China. Data sourced from the 2013 and 2015 waves of the China Health and Retirement Longitude Survey (CHARLS) are utilised for the analysis. We find a distinct gender difference in terms of working decisions at an older age: not only are men more likely to work than women, but financial pressure and marriage are correlated with a man’s propensity to work. However, these factors have very little impact on women. Contrary to findings reported in previous literature, care responsibilities for parents does not have a statistically significant impact on an individual’s working decision. In addition, the impact of caring responsibilities for grandchildren, while statistically significant, does not differ between men and women in China

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Differential response of apoptosis-regulatory Bcl-2 and Bax proteins to an inflammatory challenge in the cerebral cortex and hippocampus of aging mice.
No full textApoptosis plays a key role in normal aging and neurodegeneration. It is now known that normal aging implies low-grade inflammation and increases susceptibility to neurodegenerative diseases, which, in turn, include a neuroinflammatory component. We here investigated, using mice of 2-3 months, 10-11 months, or 18-21 months of age, the expression of apoptosis-regulatory proteins in cortical brain regions in response to intracerebroventricular administration of pro-inflammatory cytokines. A mixture of interferon-gamma and tumor necrosis factor-a was injected, using vehicle (phosphate-buffered saline) as control. At 4 days, levels of the anti-apoptotic Bcl-2 and pro-apoptotic Bax proteins in the cerebral cortex and hippocampus, examined with Western blotting, were markedly upregulated by cytokine exposure in mice of all age groups with respect to controls. Interestingly, cytokine-elicited Bcl-2 upregulation was aging-dependent, with significant enhancement paralleling the animals' age. Cytokine-elicited Bax expression did not exhibit instead significant aging-related variation. Using the same paradigm and 1 or 2 day survival, Bcl-2 immunoreactivity was observed mainly in neurons of cortex and hippocampus of both control and cytokine-treated mice of all age groups. Furthermore, immunohistochemistry confirmed the enhancement of cytokine-elicited Bcl-2 expression in the cerebral cortex and hippocampus of old mice, and showed that this finding was already evident in the second day after cytokine exposure. The data point out the novel finding that Bcl-2 and Bax expression in cortical brain regions is differentially regulated during senescence in response to an acute inflammatory challenge. Aging-related Bcl-2 increases in neurons after cytokine exposure could contribute to amplify neuroprotective mechanisms in the old brai
