The mental health of expatriate and Kosovar Albanian humanitarian aid workers

The mental health consequences of exposure to traumatic events and the risk factors for psychological morbidity among expatriate and Kosovar Albanian humanitarian aid workers have not been well studied. In June 2000, we used standardised screening tools to survey 285 (69.5%) of 410 expatriate aid workers and 325 (75.8%) of 429 Kosovar Albanian aid workers from 22 humanitarian organizations that were implementing health programmes in Kosovo. The mean number of trauma events experienced by expatriates was 2.8 (standard deviation: 2.7) and by Kosovar staff 3.2 (standard deviation: 2.8). Although only 1.1% of expatriate and 6.2% of Kosovar aid workers reported symptoms consistent with the diagnosis for post-traumatic stress disorder, 17.2% and 16.9%, respectively, reported symptoms satisfying the definition of depression. Regression analysis demonstrated that the number of trauma events experienced was significantly associated with depression for the two sets of workers. Organisational support services may be an important mediating factor and should be targeted at both groups.     

江苏省环境与人口、经济的协调发展分析——基于环境安全视角

协调发展既是国民经济乐观发展的客观要求,同时也是人类可持续发展不可或缺的组成部分。江苏省协调发展问题的研究有利于解决环境问题的定位,发现环境发展中的薄弱点与发展潜力,促进环境与人口、经济的协调发展。以环境安全理论为依托,以强调协调发展为出发点,建立江苏省环境与人口、经济系统的协调发展指标体系,应用改进的层次分析法（AHP）及变异系数法权重均值赋权,借鉴模糊数学中隶属度函数来计算协调系数。结果表明：2001~2010年江苏省环境与人口、经济系统的平均协调水平处于基本协调状态,并且有稳中上升的趋势,协调发展前景乐观;同时分析并提出了建立健全江苏省协调发展机制、探讨环境安全维护体系建设、制订缓解人口压力政策等建议

14个有价值的城市安全系统学理论基础问题

安全系统学是安全科学的核心基础理论,很适用于研究城市系统安全问题。本文从认识论和本体论出发阐述系统发生事故的本质原因,归纳了城市安全需要研究全生命周期与全球视野问题、微系统—中系统—宏系统耦合匹配问题、可持续—智慧—公共服务—多系统—生活生产安全—公共安全协同问题、输入与输入平衡关系、应急与涌现关系、信息与安全情报关系、安全管理与自组织关系、复杂城市与复杂科学关系,简述本质安全并非基础设施安全、风险管理需要精准安全、韧性并非物理性问题,认为使命—人—机—物—管—环—信—文的体系,以及工程—教育—管理—文化等对策应赋予新的安全内涵。上述内容是城市系统安全学的重要理论基础问题。     

Urban wild meat consumption and trade in central Amazonia

The switch from hunting wild meat for home consumption to supplying more lucrative city markets in Amazonia can adversely affect some game species. Despite this, information on the amounts of wild meat eaten in Amazonian cities is still limited. We estimated wild meat consumption rates in 5 cities in the State of Amazonas in Brazil through 1046 door-to-door household interviews conducted from 2004 to 2012. With these data, we modeled the relationship between wild meat use and a selection of socioeconomic indices. We then scaled up our model to determine the amounts of wild meat likely to be consumed annually in the 62 urban centers in central Amazonia. A total of 80.3% of all interviewees reported consuming wild meat during an average of 29.3 (CI 11.6) days per year. Most wild meat was reported as bought in local markets (80.1%) or hunted by a family member (14.9%). Twenty-one taxa were cited as consumed, mostly mammals (71.6%), followed by reptiles (23.2%) and then birds (5.2%). The declared frequency of wild meat consumption was positively correlated with the proportion of rural population as well as with the per capita gross domestic product of the municipality (administrative divisions) where the cities were seated. We estimated that as much as 10,691 t of wild meat might be consumed annually in the 62 urban centers within central Amazonia, the equivalent of 6.49 kg per person per year. In monetary terms, this amounts to US$21.72 per person per year or US$35.1 million overall, the latter figure is comparable to fish and timber production in the region. Given this magnitude of wild meat trade in central Amazonia, it is fundamental to integrate this activity into the formal economy and actively develop policies that allow the trade of more resilient taxa and restrict trade in species sensitive to hunting.
