A sequence of computer experiments is used to study questions concerning the tsunami problem as a quantitative estimate of tsunami danger, detailed geographical tsunami classification, determination of the parameters of critical tsunami waves, and the conditions of their development. We call a wave critical, if its impact on the coast is most hazardous.Using the Middle Kuril Island as an example, we present the results of a computer experiment which includes determining the wavefields on the shelf and estimating the effects connected with the deep-water Bussol and Diana Straits.Numerical simulation of tsunami waves of different sources permits the assessment of the extent of tsunami danger in different areas of the coastal zone of Simushir Island, depending on the location of the focus zone and their geometry.The major singularities of the wavefield arise in the zones of the deep-water straits. The distribution of the amplification factors is determined by both the global parameters of the wavefields and the local properties of individual harbours. The results obtained for a particular harbour in the northern part of Simushir Island, formed the basis for the quantitative estimate of tsunami danger for this area. 相似文献

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 Florida State University (FSU) multimodel superensemble forecast is evaluated against several other operational weather models for the Southeast Asia region. The superensemble technique has demonstrated its exceptional skills in forecasting precipitation, motion and mass fields compared to either individual global operational or ensemble mean forecasts. The motion field investigation for the season of 2001 reveals that the superensemble forecasts are closer to the observed data compared to the other global member operational models through its low systematic errors at the 850 hPa level. The FSU multimodel superensemble forecasts exhibit the lowest root mean square errors (RSMEs), the highest correlation against the best observed data and the lowest systematic errors compared to the other operational model members. These forecasts have the potential to provide better daily weather predictions over the Southeast Asia region, particularly during the early northeast monsoon that often causes heavy rainfall in the equatorial part of the Southeast Asia region. 相似文献
