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.     

‘Public toilets for a diverse neighborhood’: Spatial purification practices in community development discourse

This paper explores the dialectic of place and community identity in Mount Pleasant, a multi–ethnic and multi–class U.S. neighborhood where definitions of place are hotly contested among its residents. In a grant proposal for public toilets, Mount Pleasant writers use linguistic strategies such as presupposition, deixis, and contrast, coupled with discursive themes of filth and geography, to construct a core of the Mount Pleasant community. The writers place themselves and people who share their values in that core, and immigrants at the margins. These strategies serve as a discursive type of spatial purification practice (cf. Sibley 1988) through which the grantwriters set up a moral and spatial order where they and other core community members are deemed to use space ‘appropriately’, and thus inhabit positive moral positions, while immigrant community members’ imputed ‘inappropriate’ use of space is used to construct negative moral positions for them.     

Presidential Address: Heroes,Warriors, and Burqas: A Feminist Sociologist's Reflections on September 11

My presidential address looked back at the gendered imagery of American heroes and warriors, Muslim terrorists, and oppressed Islamic women as they appeared in comparatively sophisticated media sources in the first 6 months after September 11. The imagery was conventionally gendered, but the actions of women and men reported in the same sources showed multiple gendering—heterogeneity within homogeneity. Making this multiplicity of gendering visible blurs and undermines gender lines and the inequities built on them. The social constructions of heroism, masculinity, and Islamic womanhood are core parts of the gender politics of September 11, a politics deeply embedded in the current debates over the causes and consequences of terrorism and war.

LF拓扑空间的商空间的同胚

利用满映射f:X→Y诱导的L值Zadeh型函数f:L^X→L^Y和LF拓扑空间（L^X,δ）构造商空间（L^Y,μ）；又由f建立X上等价关系－，得出自然投影P：X→X／－，再得用P诱导的L值Zadeh型函数P：L^X→L^X/-和（L^X,δ）构造商空间（L^X/-,μ^*），证明了两商空间同胚。     

有机污染物降解的光化学及微生物降解方法探索

随着塑料用途的不断扩大和消费量的日益增长，塑料废弃物也与日俱增，环境污染和社会公害等问题也日趋严重。塑料废弃物具有不易降解性，它不仅污染环境（土壤、水源等），还会阻止其它物质的降解。文章试图从基本机理入手，找到有机物降解的最有效途径，以达到保护环境、节约能源的目的。     

八角茴香油的实验室提取方法

根据八角茴香油中的主成份是八角茴香脑（约占80％－90％），其精油颜色为无色至淡黄色液体，低温时为白色结晶，mp为22.5℃－23℃，能溶于乙醇，几乎不溶于水，一般采用乙醇回流法或索氏提取法从八角茴香粉末中提取精油。     

听力课与视听课相结合的新模式

学校原有的语言实验室、视听实验室各有局限，已不能满足教学需要。因此，对两个实验室的两套设备进行具体的技术改造，组建成了一个新的功能更加完善的语言与视听实验室，从而大大提高了听力与视听课的教学质量。     

《礼记·乐记》作于公孙尼之说辨误

《礼记·乐记》是一份集中体现先秦儒家音乐思想与礼教思想的重要文献。过去，人们一直以为它的作者是孔子的再传弟子公孙尼。本文通过分析考证，以可靠的文献资料为依据，否定了这种错误的观点。澄清《乐记》的作者问题，对于我们准确理解《乐记》以至整部《礼记》的编纂性质，从而正确而有效地发挥其文献功能，具有重要意义。
