Chicago’s gay village of Boystown has long been linked with whiteness, and in the past decade, tensions have flared between neighborhood residents and queer and transgender (trans) youth of color, often homeless, who come to Boystown for the many services provided by its lesbian, gay, bisexual, transgender, and queer (LGBTQ) nonprofit organizations, or queer spaces of care. While scholars have attended to community policing in Boystown through the Take Back Boystown movement, the role of LGBTQ nonprofits has yet to be examined in their role of criminalizing queer and trans youth of color in the neighborhood. Through an autoethnographic approach, this paper explores how several nonprofit organizations in Boystown have adopted policing strategies toward the queer and trans youth of color they serve. I argue that community policing has infiltrated these organizations to further defend and maintain an exclusive gay urban space informed by whiteness, which marks and regulates young, Black masculinities and trans femininities as deviant, untrustworthy, and criminal. Racism diminishes the ability for queer spaces of care to fulfill their mandates of supporting queer and trans youth of color, rendering the neighborhood a space of surveillance and furthering a White gay urban belonging that alienates and criminalizes these youth. 相似文献

The area south and east of the Baltic Sea has very minor seismic activity. However, occasional events occur as illustrated
by four events in recent years, which are analysed in this study: near Wittenburg, Germany, on May 19, 2000, M
w = 3.1, near Rostock, Germany, on July 21, 2001, M
w = 3.4 and in the Kaliningrad area, Russia, two events on September 21, 2004 with M
w = 4.6 and 4.7. Locations, magnitudes (M
L and M
w) and focal mechanisms were determined for the two events in Germany. Synthetic modeling resulted in a well-confined focal
depth for the Kaliningrad events. The inversion of macroseismic observations provided simultaneous solutions of the location,
focal depth and epicentral intensity. The maximum horizontal compressive stress orientations obtained from focal mechanism
solutions, approximately N–S for the two German events and NNW–SSE for the Kaliningrad events, show a good agreement with
the regionally oriented crustal stress field. 相似文献

Relict fluvial and lacustrine deposits in the interior of Oman near Saiwan consist of waterlain breccias with pebble imbrications and current ripples, covered by algal laminites containing calcified reeds and charcoal pieces. Geomorphological evidence suggests that the palaeolake covered a maximum surface of 1400 km2 and had a maximum depth of about 25 m. Optically stimulated luminescence (OSL) and thermally transferred OSL dating indicate that this palaeolake existed sometime between 132 and 104 ka. The rich archaeological evidence in the area suggests substantial human occupation, possibly at the time when Palaeolake Saiwan existed. Interestingly, the lithic traditions of the archaeological material show no clear relation to coeval findings from neighbouring areas, putting a question mark on the origin of the culture found at Saiwan. This finding raises questions concerning the origin of the population inhabiting Saiwan, as the site lies along one possible route for the dispersal of anatomically modern humans out‐of‐Africa.

There is mounting evidence that permafrost degradation has occurred over the past century. However, the amount of permafrost lost is uncertain because permafrost is not readily observable over long time periods and large scales. This paper uses JULES, the land surface component of the Hadley Centre global climate model, driven by different realisations of twentieth century meteorology to estimate the pan-arctic changes in near-surface permafrost. Model simulations of permafrost are strongly dependent on the amount of snow both in the driving meteorology and the way it is treated once it reaches the ground. The multi-layer snow scheme recently adopted by JULES significantly improves its estimates of soil temperatures and permafrost extent. Therefore JULES, despite still having a small cold bias in soil temperatures, can now simulate a near-surface permafrost extent which is comparable to that observed. Changes in snow cover have been shown to contribute to changes in permafrost and JULES simulates a significant decrease in late twentieth century pan-Arctic spring snow cover extent. In addition, large-scale modelled changes in the active layer are comparable with those observed over northern Russia. Simulations over the period 1967–2000 show a significant loss of near-surface permafrost—between 0.55 and 0.81 million km2 per decade with this spread caused by differences in the driving meteorology. These runs also show that, for the grid cells where the active layer has increased significantly, the mean increase is ~10 cm per decade. The permafrost degradation discussed here is mainly caused by an increase in the active layer thickness driven by changes in the large scale atmospheric forcing. However, other processes such as thermokarst development and river and coastal erosion may also occur enhancing permafrost loss. 相似文献

Climate scientists have played a significant role in investigating global climate change. In the USA, a debate has swirled about whether a consensus on climate change exists among reputable scientists and this has entered the policy process. In order to better understand the views of US climate scientists, we conducted an empirical survey of US climate scientists (N?=?468) in 2005, and compared the results with the 2007 Intergovernmental Panel on Climate Change (IPCC) physical science report and policy summaries. Our results reveal that survey respondents generally agree about the nature, causes, and consequences of climate change, and are in agreement with IPCC findings. We also found that there is strong support for a variety of policy initiatives to reduce greenhouse gas emissions. 相似文献

Fluvial flood risk in Europe in present and future climates 总被引:2,自引:0,他引:2

In this work we evaluate the implications of climate change for future fluvial flood risk in Europe, considering climate developments
under the SRES A2 (high emission) and B2 (low emission) scenario. We define flood risk as the product of flood probability
(or hazard), exposure of capital and population, and vulnerability to the effect of flooding. From the European flood hazard
simulations of Dankers and Feyen (J Geophys Res 114:D16108. doi:, 2009) discharges with return periods of 2, 5, 10, 20, 50, 100, 250 and 500 years were extracted and converted into flood inundation
extents and depths using a planar approximation approach. Flood inundation extents and depths were transformed into direct
monetary damage using country specific flood depth-damage functions and land use information. Population exposure was assessed
by overlaying the flood inundation information with data on population density. By linearly interpolating damages and population
exposed between the different return periods, we constructed damage and population exposure probability functions under present
and future climate. From the latter expected annual damages (EAD) and expected annual population exposed (EAP) were calculated.
To account for flood protection the damage and population exposure probability functions were truncated at design return periods
based on the country GDP/capita. Results indicate that flood damages are projected to rise across much of Western Europe.
Decreases in flood damage are consistently projected for north-eastern parts of Europe. For EU27 as a whole, current EAD of
approximately €6.4 billion is projected to amount to €14–21.5 billion (in constant prices of 2006) by the end of this century,
depending on the scenario. The number of people affected by flooding is projected to rise by approximately 250,000 to 400,000.
Notwithstanding these numbers are subject to uncertainty, they provide an indication of potential future developments in flood
risk in a changing climate. 相似文献
