在20世纪初,发生了一场被后人称之为"语言转向"的运动.维也纳学派在这场运动中起着至关重要的作用,他们通过对基本逻辑句法的分析,表明传统的形而上学命题并没有认识论的意义.同时,他们也意识到,尽管这场运动需借助现代逻辑才能进行,但是,它关注的问题却深刻得多,那就是逻辑后面所蕴含的本质.也就是说,逻辑形式体现出所有知识的共同的东西.这种逻辑至上的观点自有其合理性,但是,它的目标注定是无法达到的.这是因为,产生于社会生活中的逻辑最终还是受社会生活所制约.  相似文献

To increase employment from desired race or gender groups, employers nearly always first turn to recruiting from outside their organization. But a few years after such initiatives are undertaken, diversity numbers typically remain low or even decrease, turnover among recruits from the sought‐after groups is high, and the efforts are threatened by their recurrent cost. Employers need to break this fruitless cycle by thinking more strategically. Without an inclusive organizational climate that retains and fully utilizes minority employees after hire, simply recruiting more such employees will not lead to sustainable changes in workforce demographics. Drawing on empirical research, this paper describes six “red flags” that identify workplaces not ready to recruit. Only after organizational changes address the deficiencies identified by the red flags will the time for minority recruitment be at hand. But by then special focused recruitment may not be necessary; when employers change their workplace cultures to become truly inclusive, word gets around.  相似文献

In clinical trials with repeated measurements, the responses from each subject are measured multiple times during the study period. Two approaches have been widely used to assess the treatment effect, one that compares the rate of change between two groups and the other that tests the time-averaged difference (TAD). While sample size calculations based on comparing the rate of change between two groups have been reported by many investigators, the literature has paid relatively little attention to the sample size estimation for time-averaged difference (TAD) in the presence of heterogeneous correlation structure and missing data in repeated measurement studies. In this study, we investigate sample size calculation for the comparison of time-averaged responses between treatment groups in clinical trials with longitudinally observed binary outcomes. The generalized estimating equation (GEE) approach is used to derive a closed-form sample size formula, which is flexible enough to account for arbitrary missing patterns and correlation structures. In particular, we demonstrate that the proposed sample size can accommodate a mixture of missing patterns, which is frequently encountered by practitioners in clinical trials. To our knowledge, this is the first study that considers the mixture of missing patterns in sample size calculation. Our simulation shows that the nominal power and type I error are well preserved over a wide range of design parameters. Sample size calculation is illustrated through an example.  相似文献

ABSTRACT

Large-scale population studies surveying young people in relation to their worldviews have tended to frame their identities in a fixed and limited capacity while also treating the topics of religion/spirituality and sexuality/gender as discrete categories of scholarly analysis. We highlight the affordances and limitations of foregrounding fixed religious, sexual and gender-based identity categories in the process of collecting and analysing data related to the worldviews of young people. In this paper we argue the value of studying the complexities and intersections of these identities and worldviews together in one study. We do this through reference to the Australia’s Generation Z (AGZ) study: the first nationally representative sample focused on providing an evidence-based understanding of both the religious/spiritual/non-religious and sexuality/gender identities and worldviews of young Australians aged 13–18. We discuss how we built on existing surveys in designing the AGZ survey. We also demonstrate how this survey allowed for the incorporation of young people’s non-binary understandings of religion, sexuality and gender.  相似文献

This paper reviews the literature on social inclusion and social capital to develop a framework to guide the selection of items and measures for the forthcoming SA Department of Human Services Survey of Social Inclusion to be held in the region of Northern Adelaide in South Australia. Northern Adelaide is a region with areas of high socio-economic disadvantage, characterized by high unemployment and poverty. Survey respondents’ perceptions of social inclusion and social capital in Northern Adelaide will be examined by developing indices, which address the theoretical schema discussed in this paper. Epistemological differences between seminal theorists on social inclusion and social capital suggest the development of a broad suite of indices is required to enable the collection of data of interest to researchers from differing theoretical perspectives. Data collected in the survey will be mapped using Geographic Information System (GIS) technologies against locations within Northern Adelaide and in relation to existing Australian Bureau of Statistics, Commonwealth and State Government databases on age, gender, relative socio-economic disadvantage and other variables.  相似文献

卡瑞.邱吉尔是英国当代著名的女剧作家。她的力作《九重天》描述了女性在父权制下受压迫的状况,向建立在男女社会性别差异和异性恋基础上的传统家庭发起了抨击。她构建了一个反传统,无性别及家庭角色压迫,充满多重性欲的乌托邦,进而解构了本质主义在性别上的二元对立。剧中,邱吉尔把殖民压迫和性别压迫并置,并采用了反串的戏剧技巧,进一步加深了性别压迫的主题。  相似文献

传统理论认为,个人的全面自由发展只能存在于“必需和外在规定要做的劳动的彼岸”,只能通过缩短劳动时间、消灭专业分工才能实现。但从知识经济的发展趋势看,社会总劳动及人们的实际劳动时间不可能减少,专业分工也不可能消灭。这意味着,我们善于个人全面发展的理论应当修正。笔者认为,一种集谋生劳动和自由活动,专业分工和全面发展于一身的新型劳动———知识创新劳动将成为人们实现自由全面发展的现实途径。  相似文献
