Highlights from a low-level area: infant mortality and social structure in eight East Frisian parishes, 1740–1839

Considerable variations in infant mortality rates have occurred within the low-lying region of northern Germany's East Frisia. Individual parishes can be assigned to three specific groups by registered mortality levels for the period 1740–1839. Differences also existed between parishes containing Geest (heathland), bogs, and marshland reflecting specific geographical and environment factors, as well as the structure of the local economy. In both Geest and bog parishes, the level of infant mortality and its trend over time were not homogeneous. In the two marshy river parishes, only environmental factors were significant; both registered the lowest rates of infant mortality. They had fertile soil, extensive grazing land, an exceptionally high number of large agricultural holdings, and households that were above average in size. By contrast, the highest rates of infant mortality were found in one bog and two Geest parishes, but these communities remained heterogeneous in terms of geographical size and population growth and density.

亚洲债券基金的推出背景、影响及发展方向

以银行信贷为主的金融体系使东亚地区面临两大问题,即巨大的金融风险和盈余资金利用效率低下,这也是亚洲金融危机中有关各方脆弱表现的直接原因。为了解决这两个问题或缓解其造成的危害,东亚各国(地区)纷纷提出方案,亚洲债券基金(ABF)作为一个阶段性成果,目前已经推出两期,分别为ABF1和ABF2。虽然亚洲债券基金在推动亚洲债券市场发展方面有一定的积极影响,但是其局限性也很明显,未来的发展方向主要是投资对象和投资主体的多元化。     

IMMIGRATION POLICY,BORDER SECURITY,AND MIGRANT DEATHS: AN IMPACT EVALUATION OF LIFE‐SAVING EFFORTS UNDER THE BORDER SAFETY INITIATIVE*

Subsequent to U.S. Border Patrol (USBP) efforts to control illegal immigration throughout the 1990s, concern arose over an apparent increase in deaths of illegal migrants as they began to undertake more treacherous routes to enter the United States from Mexico. In response, the Border Safety Initiative (BSI) was created to increase safety along the southwest border. Using multiple data sources, including the USBP BSI Incident Tracking System, this study evaluated the impact of life‐saving efforts performed under the BSI program. Results indicate that there has been no overall reduction in the rate of migrant deaths since BSI has been in operation. However, an evaluation of BORSTAR search and rescue teams and the 2003 Lateral Repatriation Program (LRP), which returned apprehended migrants from Tucson sector to less hazardous places along the border, were found to be effective in preventing migrant deaths. Policy Implications: Critics of U.S. immigration policy claim that the only way reductions in migrant deaths along the U.S.‐Mexico border can be achieved is through liberalization of immigration policy and relaxing of border security. Yet, for more than a decade, U.S. policy makers have increased restrictions on immigration and have tightened security at the borders. Considering this, alternative means must be deployed in order to save migrant lives in the near term rather than waiting for a reversal of immigration policy. This study suggests that proactive life‐saving measures implemented through a harm‐reduction strategy can have some impact on saving migrant lives.

重大体育事件突发性公共安全问题及对策研究

城市重大体育事件是指以租用、借用或者以其他形式临时占用公共场所,面向社会公众举办,单次参加人员在10000人以上的群体性活动,包括体育比赛、体育展览展销以及含有竞技色彩的民俗活动等。在重大体育事件过程中,突发性公共安全危害可分为群体械斗事件、拥挤践踏事故两类。重大体育事件对地方发展具有的重要意义已成为我国各地政府的共识,但随着规模扩大和场次的增加,其安全保卫难度也随之提高。对重大体育事件安全保障战略和路径设计是:形成以政府为主导,以企业、非营利性组织为联盟的安全保障主体;构建灵活有效的危机安全防范体系;加强公众安全防范教育;注意体育场馆、公共场所的细节设计。

中东伊斯兰力量掌权前景分析

1979年伊朗伊斯兰革命成功后,中东出现了伊斯兰力量夺权的浪潮。总体来看,伊斯兰组织采取了四种策略,即政变、恐怖袭击、内战或者革命以及参加民主选举。由于各国执政者对军队的严密控制,除苏丹这个特例外,政变从未成功。恐怖袭击虽能破坏社会秩序,但无法动摇政权的根基。伊朗革命具有极强的特殊性,别国无法成功复制。而大多数中东国家中央政府相对强大,不具备发生内战的条件。因此,在中东国家实行政治改革后,参加民主选举成为获取权力最为现实可行的方式。在此情况下,越来越多的伊斯兰组织将会放弃暴力夺权的方式,淡化意识形态的色彩,与其他世俗政治派别一起公平竞争国家权力。
