New digital and biogenetic technologies-in the shape of media such as virtual reality, artificial intelligence, genetic modification and technological prosthetics- signal a 'posthuman' future in which the boundaries between humanity, technology and nature have become ever more malleable. We are more aware than ever that what we call 'nature' is open to manipulation by varieties of biotechnology such as gene therapy. Computer-assisted technologies transform perceptions of body, time and space. Dreams of merging humans and machines into new intelligent cybernetic organisms leave the realm of science fiction and enter everyday reality. As the taken-for-grantedness of what it means to be human shifts and blurs, we might consider how myth, literature and popular culture have furnished the Western imagination with a gallery of fantastic and monstrous creatures on the margins of human and non-human. One contemporary example is that of the cyborg, who serves as a metaphor of the various ways in which the contemporary west is currently experiencing the hybridization of human nature. One version of the cyborg popular with cultural theorists-especially feminists- has been the vision articulated in Haraway's 'Manifesto for Cyborgs'. Termed here as Haraway's 'cyborg writing', it expresses important values about gender, politics and technology; but whilst the cyborg subverts many of the dualisms of western culture, Haraway's comment that she would 'rather be a cyborg than a goddess' inadvertently reinforces one final, often unspoken dichotomy of modernity: that between religion and the secular. Therefore the implications for feminist theory and praxis of a recovery of the goddess are explored. To concur with Haraway, such a project is prone to an inversion of traditional gender stererotypes, enclosing women in a realm of unreconstructed 'nature' at the expense of empowering them to engage with new technologies. Other models of 'becoming divine', however, promise more radical reconfigurations of the religious symbolic of western modernity, a symbolic that has sanctioned the equation of technology with the disavowal of embodied finitude in the name of a quest for transcendence. Irigaray's concept of the 'sensible transcendental' refuses the simplistic distinctions between sacred/secular, spiritual/material, divine/human. Far from representing a female version of the patriarchal sky-god, or even a bucolic, romanticized 'mothergoddess', therefore, Irigaray's model of 'becoming divine' offers an exciting addition to the critical and reconstructive resources of cyberfeminism.  相似文献

The literature on gender differences in orientations to work among Protestant clergy has been mixed, but generally points to the hypothesis that female clergy hold fewer career and professional work values than their male counterparts. This expectation flies in the face, however, of other more general population studies that show women and men hold similar work values and orientations to work. Using a national sample of clergy from two Protestant denominations, we test for gender differences in these values and orientations. Consistent with the general population findings, female clergy have professional values and orientations that are just as strong, if not stronger than those of male clergy.  相似文献

A common problem with medical surveillance programs using biomarkers is determining the optimal frequency of testing to minimize adverse health effects and cost. In the case of beryllium-exposed workers, frequency of testing for beryllium sensitization may be especially important. Recent studies indicate a lack of dose response for beryllium sensitization, but do support a dose response for the development of chronic beryllium disease (CBD). Though unproven, this implies that early identification of sensitization and immediate removal from exposure may reduce development of CBD. A model is proposed to project the optimal frequency of sensitization testing using the current beryllium lymphocyte proliferation test (BeLPT) to minimize disease-related costs, assuming that a positive BeLPT will precede CBD. Conversion rates for cumulative exposure to disease development were adapted from the literature and used with testing costs and cost of disease estimates in the model. The model was run assuming several test frequency regimes. Results support the use of periodic testing in line with the annual schedule proposed in the Final Chronic Beryllium Disease Prevention Program Rule (1999) following initial testing within three months of first beryllium exposure. The financial and health benefits of reducing the time from exposure to detection of early disease was also explored with the model and demonstrated as a highly desirable characteristic for an alternative test or improved BeLPT. Limitations of the approach are discussed as well as options for adapting this biomarker optimization methodology to consider biomarkers of other exposure-associated diseases.  相似文献

A measure of comfort with touching was found to predict whether or not subjects would volunteer to participate in an experiment involving hugging strangers of both sexes and also to predict levels of personal space. Among those volunteering to give hugs, subjects reporting greater comfort with touch rated those hugs more positively, but this seemed to reflect a readiness to interpret touch positively rather than any clear differences in the nature of the hug actually given. Earlier findings that women report greater comfort with touch than do men were replicated. It was found that reported touch comfort was directly related to such constructs as satisfaction with life, with oneself, and with one's childhood, as well as to self-confidence, assertiveness, socially acceptable self-presentation, and active rather than passive modes of coping with problems. Touch comfort was inversely related to expressed concerns with touches which might reflect status differentials, homosexuality, or negative affective states. It was concluded that the touch comfort construct reflects the degree of one's openness to expressing intimate behavior, the degree to which one adopts an active, rather than passive, interpersonal style, and the degree to which one's social relationships are satisfactory.  相似文献

Sexual harassment, i.e., unwanted sexual attention, is not a new phenomenon for working women. Yet only in recent years have the behaviors constituting it been challenged and recognized as detrimental to society. This paper documents the process by which sexual harassment emerged on the public agenda. It identifies the major elements–media attention, activities of interest groups, court actions, and legislation–involved in the process of redefinition and examines how and why each promoted the issue. The data, gathered from analyses of publication and language trends, records of congressional hearings, and interviews with several participants in the process, are used to further understanding of how these elements converged during a period of social concern for women's rights and enabled a public reconceptualization of sexually harassing behaviors.  相似文献

Why do some organizational changes persist, while others decay? The sustainability of change can be defined broadly as the process through which new working methods, performance goals and improvement trajectories are maintained for a period appropriate to a given context. However, sustainability has received limited attention, although the concept reflects Lewin's concern with ‘refreezing’ ( Lewin. K. 1951 . Field Theory in Social Science: Selected Theoretical Papers by Kurt Lewin, UK edition published 1952, ed. D. Cartwright, London: Tavistock). In an uncertain environment, working practices that fail to adapt are targets for change, and stability has been regarded not as a condition to be achieved, but as a symptom of inertia, a problem to be solved. This paper reviews the emerging literature, seeking to develop a provisional model of the processes influencing change sustainability and decay, as a platform for further research. This review suggests that sustainability is dependent on multiple factors, at different levels of analysis: substantial, individual, managerial, financial, leadership, organizational, cultural, political, processual, contextual and temporal. The relative significance of those factors cannot be determined a priori, raising questions concerning the properties of the sustainability process with regard to different types of change in different contexts.  相似文献

A challenge with multiple chemical risk assessment is the need to consider the joint behavior of chemicals in mixtures. To address this need, pharmacologists and toxicologists have developed methods over the years to evaluate and test chemical interaction. In practice, however, testing of chemical interaction more often comprises ad hoc binary combinations and rarely examines higher order combinations. One explanation for this practice is the belief that there are simply too many possible combinations of chemicals to consider. Indeed, under stochastic conditions the possible number of chemical combinations scales geometrically as the pool of chemicals increases. However, the occurrence of chemicals in the environment is determined by factors, economic in part, which favor some chemicals over others. We investigate methods from the field of biogeography, originally developed to study avian species co‐occurrence patterns, and adapt these approaches to examine chemical co‐occurrence. These methods were applied to a national survey of pesticide residues in 168 child care centers from across the country. Our findings show that pesticide co‐occurrence in the child care center was not random but highly structured, leading to the co‐occurrence of specific pesticide combinations. Thus, ecological studies of species co‐occurrence parallel the issue of chemical co‐occurrence at specific locations. Both are driven by processes that introduce structure in the pattern of co‐occurrence. We conclude that the biogeographical tools used to determine when this structure occurs in ecological studies are relevant to evaluations of pesticide mixtures for exposure and risk assessment.  相似文献

The purpose of this article is to describe a standard set of age groups for exposure assessors to consider when assessing childhood exposure and potential dose to environmental contaminants. In addition, this article presents examples to show how the age groups can be applied in children's exposure assessments. A consistent set of childhood age groups, supported by an underlying scientific rationale, will improve the accuracy and comparability of exposure and risk assessments for children. The effort was undertaken in part to aid the U.S. Environmental Protection Agency (EPA) in implementing such regulatory initiatives as the 1997 Presidential Executive Order 13,045, which required all federal agencies to ensure that their standards take into account special risks to children. The standard age groups include: birth to <1 month; 1 to <3 months; 3 to <6 months; 6 to <12 months; 1 to <2 years; 2 to <3 years; 3 to <6 years; 6 to <11 years; 11 to <16 years; and 16 to <21 years. These age groups reflect a consideration of developmental changes in various behavioral, anatomical, and physiological characteristics that impact exposure and potential dose. It is expected that the availability of a standard set of early-life age groups will inform future analyses of exposure factors data as well as guide new research and data collection efforts to fill knowledge gaps.  相似文献
