Particulate emission inventory and trends in ambient particulate matter concentrations in the Czech Republic between 1993 and 1999

Trends in total suspended particulates (TSP) emissioninventories were compared with ambient TSP concentrationsduring the period of 1993-1999 in the Czech Republic. TheTSP annual emission decreased within the period of observationfrom 441 300 to 67 000 of metric tonnes (by 85%). During thesame period a less pronounced downward trend from80.3 g m^-3 to 31.5g m^-3 (decrease by 61%)was noted also for the ambient TSP annual average. Differencebetween the two air quality indicators seems to indicate thatchanges in TSP emission inventories from year to year arebeing to some extent overestimated. Monthly ambientparticulate concentrations did not respond to overall drop inemissions proportionately but were closely associated withmonthly mean temperatures. While in the winter the correlationbetween ambient TSP and temperature was negative, in summerthe correlation between the two variables was positive. Inspring and autumn there was no clear correlation betweentemperature and ambient particulate pollution. The improvementof air quality in the Czech Republic since the economical andpolitical transformation in 1990s is substantial whendemonstrated by emission figures, however, true state ofparticulate pollution expressed by ambient levels requiresfurther attention.     

Stigmatisation and rejection of survivors of sexual violence in eastern Democratic Republic of the Congo

Studies report that between 6 per cent and 29 per cent of survivors of sexual violence in eastern Democratic Republic of the Congo (DRC) are rejected by their families and communities. This research project was designed to provide insights into survivors' experiences of stigmatisation and rejection. Surveys were conducted with 310 women as they sought psychosocial services in eastern DRC. In total, 44.3 per cent of women reported suffering rejection after sexual violence. The majority of women felt that their status in the household (58.0 per cent) and community (54.9 per cent) diminished after rape. The odds of rejection were greater among women reporting ongoing displacement, pregnancy owing to sexual violence, worsening family relations, and diminished community status. This work highlights the extremely high levels of loss associated with the war in eastern DRC, particularly among survivors of sexual violence. The rejection of a survivor of rape has concrete and devastating psychosocial consequences.

Subjective modeling choices and the robustness of impact evaluations in conservation science

Arbitrary modeling choices are inevitable in scientific studies. Yet, few empirical studies in conservation science report the effects these arbitrary choices have on estimated results. I explored the effects of subjective modeling choices in the context of counterfactual impact evaluations. Over 5000 candidate models based on reasonable changes in the choice of statistical matching algorithms (e.g., genetic and nearest distance mahalanobis matching), the parametrization of these algorithms (e.g., number of matches), and the inclusion of specific covariates (e.g., distance to nearest city, slope, or rainfall) were valid for studying the effect of Virunga National Park in Democratic Republic of the Congo on changes in tree cover loss and carbon storage over time. I randomly picked 2000 of the 5000 candidate models to determine how much and which subjective modeling choices affected the results the most. All valid models indicated that tree cover loss decreased and carbon storage increased in Virunga National Park from 2000 to 2019. Nonetheless, the order of magnitude of the estimates varied by a factor of 3 (from −4.78 to −13.12 percentage points decrease in tree cover loss and from 20 to 46 t Ce/ha for carbon storage). My results highlight that modeling choices, notably the choice of the matching algorithm, can have significant effects on point estimates and suggest that more structured robustness checks are a key step toward more credible findings in conservation science.     

论水污染物排放许可证制度的法律规制——《中华人民共和国行政许可法》在水污染防治中的作用

我国部分地方规定了水污染物排放许可证制度,由于此类法律文件法律效力的低层级性,制约着水污染防治的司法与执法实践。提高设定该制度法律文件效力位阶,不仅可以解决调整该制度法制不统一状况,而且为其进行法律规制提供了直接、具体的法律依据。对促使排污主体科学、合理排污将起到积极作用。     

中国反食物浪费监测与评估体系建设

《中华人民共和国反食品浪费法》的颁布与实施,标志着中国的食物浪费从理论研究转向实践应用。为了推动食物浪费的减量,亟需构建覆盖全国的、系统性的监测和评估体系并实现食物浪费的定量监测与评估。本文面向《中华人民共和国反食品浪费法》实施过程政府及社会中各界的主要关切,通过系统梳理国内外食物浪费的相关研究,辨析了食物浪费的定义及主要演变,论述了全球食物浪费监测与评估情况。在此基础上,本文重点分析了中国食物浪费监测与评估进展,提出了通过餐厨垃圾,将食物浪费从传统概念向广义概念延伸的理念,并提出了适合中国国情的反食品浪费监测与评估指标。本文旨在为中国相关政府部门开展食物浪费的监测和评估提供科学参考,从而为全球可持续发展目标12.3的实现提供借鉴。     

Rebuilding and strengthening health systems and providing basic health services in fragile states

The international community has compelling humanitarian, political, security and economic reasons to engage in rebuilding and strengthening health systems in fragile states. Improvements in health services and systems help to strengthen civil society and to restore legitimacy to governments. Effective engagement with fragile states to inform the design of health programmes and selection of interventions depends on donor coordination and an understanding of health system challenges. Planning requires consideration of allocation (services to be delivered), production (organisation of services), distribution (beneficiaries of services) and financing. The criteria for selecting interventions are: their impact on major health problems; effectiveness; the possibility of scale-up; equity; and sustainability. There are various options for financing and models of engagement, but support should always combine short-term relief with longer-term development. Stakeholders should aim not only to save lives and protect health but also to bolster nations' ability to deliver good-quality services in the long run.     

论民国初年我国的政府救灾行政系统

作为国家行政要务的救灾,民国初年中央政府救灾机关是内务部,内务部的权力职掌有一个变化的过程;虽然其名义上作为中央一级专门救灾机构,但由于机构初设.经验不足,再加上其他诸多因素的限制,无论是部务还是权限与其他部门如财政部,农商部等都颇有纠缠.至于地方政府救灾机构,作为地方政府组织机构的一部分,虽属专管,但有兼管之嫌.一些专门的赈济机构,只不过有时囡灾于公署内暂设,事毕即行撤消.当时除了政府救灾机构外,还存在着具有亚政府色彩社会救灾力量.内务部与地方救灾系统之隶属关系相对自由,并从上到下形成了一个错综复杂的网络格局.总体而论,民国初年的救灾机构从中央到地方都比清末进一步完善,其业务范围也逐渐趋于稳定,但由于中央政权极不稳定,内阁更替频繁,致使中央和地方国家机构撤设变化较多,从而引起救灾机构的相形混乱.     

Towards a natural disaster intervention and recovery framework

Contemporary responses to facilitate long‐term recovery from large‐scale natural disasters juxtapose between those of humanitarian agencies and governments and those of the affected community. The extent to which these mechanisms articulate is crucial to the recovery propensity of the affected communities. This research examines such action by exploring the relationship between the scale of post‐disaster response interventions, the extent of community participation in them, and their impact on community recovery, using a community wealth capital framework. The investigation was applied to a study of the longer‐term community recovery of the island of Vilufushi, Republic of Maldives, which was almost completely destroyed by the Indian Ocean tsunami of 26 December 2004. Data were analysed through the employment of a pattern match technique and a holistic recovery network analysis. The research framework, informed by the case‐study results, other long‐term recovery evaluations, and existing resilience theory, is reconfigured as a testable roadmap for future post‐disaster interventions.     

论民初我国救灾成效不彰及其原因

民国初年,我国救灾的成效方面存在着相当的不足,并直接引起连带性恶性效果。影响民国初年救灾成效不佳的原因主要可以归纳为三点,即:施政重点倾斜、社会动荡不安、政府救灾功能减弱等。
