Gender differences in willingness to compete: The role of public observability

A recent literature emphasizes that gender differences in the labor market may in part be driven by a gender gap in willingness to compete. However, whereas experiments in this literature typically investigate willingness to compete in private environments, real world competitions often have a more public nature, which introduces potential social image concerns. If such image concerns are important, and men and women differ in the degree to which they want to be seen as competitive, making tournament entry decisions publicly observable may further exacerbate the gender gap. We test this prediction using a laboratory experiment (N = 784) that varies the degree to which the decision to compete, and its outcome, is publicly observable. We find that public observability does not alter the magnitude of the gender gap in willingness to compete in an economically or statistically significant way.     

疲劳裂纹扩展试验裂纹图像采集系统

针对目前金属疲劳裂纹扩展检测方法存在效率低、操作繁琐、精度不高，不能实现实时性等缺点，文章提出了基 于机器视觉的裂纹检测方法。根据金属疲劳裂纹扩展试验过程中裂纹图像的采集要求，设计了摄像头位置可自动调整 的疲劳裂纹图像采集系统，包括摄像头安装运动装置，裂纹图像采集装置以及摄像头运动控制系统。图像采集装置由高 分辨率黑白面阵CCD摄像头、光学镜头，光源照明装置和图像采集卡组成，前3者安装在摄像头支架上，与摄像头运动 装置相连。摄像头运动装置中的X，Y，，Z轴运动机构由步进电机带动滚珠导轨机构。在基于ARM技术的运动控制系统 的控制下摄像头可沿X，Y，，Z轴作高精度直线运动，实现和试件之间精确位置的调整。实验结果表明，所设计的系统可 采集到疲劳裂纹扩展试验过程中高清晰度、高分辨率的试件裂纹图像，满足下一步裂绞尺寸计算的要求；摄像头运动定 位精度可达到0. 02 mm，满足精确的系统聚焦、位置调整、跟踪采集的要求。

大众传播中的“国家教师”媒介形象分析

运用传播学内容分析法，以中央媒体对获得"全国教书育人楷模"和"最美教师"荣誉称号的"国家教师"相关报道为研究对象，从外在和内在两个方面对大众传播的"国家教师"媒介形象进行分析。外在形象包括教师性别、年龄、教龄、外表、场景以及任教的学校类别、区域、学科专业等方面，内在形象包括职业精神、职业知识和职业能力等方面。研究发现，大众媒体对"国家教师"形象的刻画和宣传符合社会公众认知教师职业的基本逻辑，起到了传递教师精神、端正教师形象、唤起社会尊重教师的功效，但也存在城乡教师形象传播刻板化以及教师普通人形象展现不充分等问题，可在后续的传播中对"国家教师"形象的价值倾向进行适当调整。     

Absent bodies and present memories: marking out the everyday and the future in Eastern Sri Lanka

Drawing from ethnographic work carried out between 2005 and 2007, this article considers the ways in which a women’s network has developed strategies to find meaning around the absences of loved ones, killed or ‘disappeared’ during the decades of conflict in Sri Lanka. For most of these women, the fate of their husbands, brothers, sons and fathers is not known and the lack of answers means that they are unable to fully grieve and find closure. In order to survive, they must find ways to deal with the absent bodies and present memories of those who may never be located and accounted for. These strategies include tree-planting ceremonies carried out as a way of not only remembering and mourning loved ones but also asking questions about how one makes sense of loss and what it means to carry the burden of unanswered absences through everyday life and into the future.     

Overcoming Old in Age-Friendliness

In this article, we explore views on an age-friendly space in the Netherlands by analysing the responses of older individuals (N = 54) in focus groups and by examining the perspectives around an age-friendly zone in the Netherlands, Parkstad Limburg. We found that a central issue in the wishes for living at a later age are adjustments to envisioned physical limitations that come with the ageing process; this includes adjustments to ensure safety, accessibility and mobility, in order to facilitate older individuals' efforts to stay engaged with the world around them. In their wishes, the older participants constructed ideal dwelling places that closely resembled a senior home, but at the same time they rejected wishing to live in a place that was identified as a senior home. We explain this paradox by the representation of such a space as being for old people, i.e. needy older individuals, which was not how the older participants wished to be identified. We conclude that the conception of age-friendly environments will have to face the difficult challenge of overcoming the association with old age, while simultaneously taking into account adjustments that signify and relate to the ageing process and that seem inescapably tied to oldness.

Tracing Differentiation in Gendered Leadership: An Analysis of Differences in Gender Composition in Top Management in Business,Politics and the Civil Service

The aim of this article is to discuss the relationship between the gendering of leadership positions and sector‐specific structures within politics, business and the civil service in Denmark in the context of differences between the Nordic countries and other western countries. The analysis is based on data from a survey of top male and female leaders within the three sectors. The theoretical point of departure of this article is constructivist. It looks at gender as constituted by actions in social space, orchestrated by structural processes and a symbolic order of gender. This constitutes a cultural discourse on gender reflected in gender conventions in society and in a range of possibilities of gender positioning. Expressions of this are discussed in the analysis of the patterns of difference in structural conditions for women and men in leadership positions to be found within the three sectors. The structural conditions encompass access conditions and conditions for gendered positioning and are analysed on the basis of data on social background, education, career course, family, children and distribution of housework. The analysis shows that there is a correlation between gender composition of leadership and possibilities of gendered positioning within a sector. The results are finally discussed as possible expressions of an egalitarian culture.
