Despite the increasing public profile of same-sex issues, health policies are often shaped by heteronormative assumptions.
The health concerns of lesbian, gay, bisexual, transsexual/transgender, two-spirit, intersex, queer and questioning (LGBTTTIQQ)
people are complex and require broadening from an often exclusively sexual health and risk focus to a more holistic approach.
In this context, this paper illustrates how a critical feminist geography of health, with its focus on the mutual construction
of gender relations, space and place, potentially enhances and extends current understandings of public health policy and
practice. Moreover, the use of a policy lens foregrounding gender and other power relations suggests that feminist research
and coalitions facilitate participatory processes that address “the politics of discourse.” In particular, public health nursing
practice can enhance the construction of spaces of resistance that challenge heteronormative discourse through research strategies
focused on sexual minority communities’ health experiences and their visions for supportive care. In this respect, two strategies
consistent with public health priorities to increase knowledge and participate in alliances are described. Ethnographic research
with childbearing lesbians demonstrates that attention to institutional dynamics that foster safe spaces can facilitate access
to public health services. Public health nurses’ involvement in community coalitions can enhance dissemination of community
knowledges. The implications for gender inclusive and place-sensitive public health nursing practice include the development
of sensitive educators, meaningful educational curriculum and related program planning, explicit policies, community partnerships
and political leadership in institutional and research venues. 相似文献

The creative reconstruction of the Internet: Google and the privatization of cyberspace and DigiPlace 总被引:2,自引:0,他引:2
The Internet has often been portrayed as the ultimate leveler of information where existing hierarchies of power and privilege are undermined by meritocracy. Some websites and functions are, however, more equal than others. In particular, search engines such as Google have been a key means to construct meaning out of disorder. This ordering (or enclosing of the Internet commons), however, comes at a cost as a location within the top 10 Google search results, marks the boundary (albeit a fluid one) between the core and the periphery of the Internet. The recent incorporation of spatial elements into the Google indexing raises fresh and geographically relevant concerns. This article focuses on the construction, access and use of Google derived rankings to deploy geo-referenced information in the physical environment and the way this melding of code and place affects how people interact with place. Using the theoretical concept of DigiPlace this article analyzes how Google Maps and Google Earth are structured and shape what appears (and what does not) in cyberspace and DigiPlace. Of particular concern are the implications of a private corporation controlling this new space. 相似文献

This paper tracks the changing role of public participation in planning thought. In doing so, the paper shows that the role of public participation in planning is largely determined by the nature of the planning enterprise being undertaken. The definition of the planning problem, the kinds of knowledge used in planning practice, and the conceptualisation of the planning and decision-making context are the important determinants of the extent of participation offered to the public. The paper therefore contributes to thinking about how to evaluate public participation by showing that it can only be understood in terms of the decision-making context in which it is embedded. Specifically, it makes little sense to evaluate public participation in terms that are not shared by the planning model itself 相似文献

GIS的社会化及公众GIS 总被引:6,自引:0,他引:6
GIS(地理信息系统 )的发展继专业化和行业化阶段之后 ,正处于社会化发展阶段。在该阶段 ,GIS的主要作用是为公众提供信息服务。文章在分析了GIS的这种发展趋势的基础上提出了“公众GIS”的概念 ,即 :直接面向公众 ,为公众提供信息服务和辅助公众进行行为决策的地理信息系统。与传统GIS相比 ,公众GIS更具有信息服务业的特点。公众GIS的建设应该突出信息的全面性、现势性和准确性、系统的友好性以及数据的易维护性等原则。公众GIS的关键技术包括数据采集、网络、数据库、多媒体以及系统的友好性设计等技术。公众GIS在建设全国城市公众信息服务网、全国交通旅游信息网以及汽车导航信息系统等方面具有广阔的应用前景。文章对公众GIS的实例———“今日武汉”公众查询系统作了简要介绍。 相似文献

现代实战数据表明,精确制导武器在战争中正发挥着越来越重要的作用。而提高武器的制导精度,也是提高武器打击效果最有效的手段。随着科学技术的发展,全球定位系统(GPS)由于其全球性、全天候以及连续实时三维定位等特点,在武器制导领域正得到越来越多的应用。本文结合GPS/INS复合制导,对GPS导航在制导中的应用进行了探讨。 相似文献
