论民国时期河南灾荒的社会成因

民国年间河南灾荒现象异常突出，虽与当时整体气候背景及河南特殊的地理特征相关，但灾荒背后的社会原因更应引起我们的关注。其主要表现为：一、社会经济乏力，百姓抗灾能力低；二、政治腐败，体现在政府的赋税名目繁多、政府官员失职渎职以及挪用、贪污河防公款等几个方面；三、战争与灾荒；四、帝国主义列强对中国的残酷掠夺。     

煤中有害元素对环境和人体健康影响的评价参数

煤中有害元素对环境和人体健康影响的较为全面的评价体系一直未建立，环保部门也缺乏系统性评价参数对电厂等在煤煤过程中有害元素排向大气的释放量进行监测估算。本文在查阅大量资料（主要为外文）的基础上，认为评价煤中有害元素对环境和人体健康影响的参数应该包括以下方面的数据C、H、O、N、无机硫，有机硫，有害微量元素的含量，分布规律，赋存状态，迁移转化行为（在燃煤过程中），洁净能力，淋滤力，矿物质，有机化学特征，煤炭学特征，并对煤中有害元素的污染方法进行探讨，如果上述各参数的数据被全面提供，并据此数据作针对性的抑制措施，煤中有害元素对环境和人体健康危害影响必将降低到最小。

国外气候变化对旅游业影响的定量研究进展与启示

加强气候变化对旅游业影响的定量研究,有助于旅游业在气候变化背景下实现可持续发展。基于SCI/SSCI文献数据库,梳理分析国外气候变化对旅游业影响的定量研究进展。结果显示,30余年来国外主要采用指标方法、需求模型与选择分析方法开展相关研究。20世纪80年代末出现的指标方法是运用最早、最广泛的方法,主要用于旅游资源环境变化等研究,呈现由单项指标转向综合指标的应用趋势;20世纪90年代末兴起的需求模型主要用于天气状况对旅游需求的影响等研究,呈现由时间序列模型转向累计需求模型的应用趋势;21世纪兴起的选择分析主要用于气候变化背景下的行为意愿等研究,呈现由描述统计转向离散选择模型的应用趋势。这些给我国研究的启示是：在研究方法与研究领域上,重点加强累计需求模型在旅游流相关研究中的运用,加强离散选择模型在旅游市场结构相关研究中的运用,加强系统科学方法与大数据技术在相关研究中的运用;在研究对象上,丰富中国境内气候敏感型旅游活动的相关研究,加强“一带一路”沿线国家、地区及青藏高原的相关研究。     

建筑企业员工职业病危害认知影响因素的调查分析

随着建筑行业的持续快速发展,建筑企业作业场所中的职业病危害呈现出高发性、复杂性和持续性等特点.通过针对建筑企业员工的实际状况设计调查问卷获取第一手资料,并运用SPSS17.0统计软件建立相关分析、回归分析等模型进行数据分析,可以得知建筑企业作业场所员工遭受职业病危害的可能性与对安全知识的了解程度、从业时间、性别及文化背景这四个因素的线性相关性.通过对建筑企业作业人员职业病危害的调查与分析,辨识出影响职业病危害的人为因素,提出相关的建议措施以改善建筑企业作业场所职业病危害严重的局面,提高建筑企业员工自我保护意识,增加其职业病危害防护知识,减少职业病危害事故的发生.

The role of social learning for soil conservation: the case of Amba Zuria land management,Ethiopia

Social learning plays key roles in sustainable natural resource management; however, studies on its role show mixed results. Even though most current studies highlight positive outcomes, there are also negative effects of social learning with respect to natural resource management. This paper explores the influence of social learning outcomes on the adoption of soil conservation practices in Amba Zuria, Ethiopia. Data were collected through semi-structured interviews, group discussions and in workshops. The interviews were transcribed and analysed with the qualitative data analysis software ATLAS.ti. In addition, a review of pertinent documents and literature complements the analysis. We found that social learning results in positive outcomes in interactions among the actors, broader understanding on soil conservation, trust and mutual understanding, and the creation of opportunities to apply both indigenous and scientific knowledge. These outcomes, in turn, foster the adoption of stone terraces to conserve soils. No such positive results were found for farmers who were not involved in the learning process and who did not adopt stone terraces. The non-adoption can partly be explained by their exclusion from sharing the positive outcomes of social learning. The study also shows limitations related to the short duration of the learning platforms, insufficient representation of women and irregular patterns of learning schedules. Hence, Ethiopian soil conservation strategies should put emphasis on social learning in order to strengthen the collective processes of soil conservation measures.     

Principal sustainability components: empirical analysis of synergies between the three pillars of sustainability

Starting from the concept of three fundamental sustainability dimensions (environmental, social, and economic), this study investigated professional contributions to sustainability by means of principal component analysis (PCA). Graduates from the Environmental Sciences program (N?=?542) at ETH Zurich described their best professional contributions to sustainable development. Next, they evaluated whether their best practice example contributed to achieving any of the five environmental, social, and economic objectives of the Swiss national sustainability strategy. These judgments served as the basis for a PCA aiming to identify principal sustainability components (PSCs) covering typical synergies between sustainability objectives within and transcending the three fundamental dimensions. Three PSCs capturing important synergies were identified. PSC 1 Product and Process Development reflects how ecological innovation and modernization can generate social and economic benefits and at the same time facilitate the reduction in use of as well as the responsible use of natural resources. PSC 2 Education and Social Economics reflects how educational activities and sociocultural sustainability initiatives can simultaneously promote income and employment, social and human capital, and free personal development. PSC 3 Protection of Nature and Humans covers the synergetic benefits which protection of natural spaces and biodiversity and the reduction of environmental risks have for the protection of health and safety of the population. The study also revealed that integration of environmental, social, and economic aspects is often connected to conflicts between these dimensions. However, contributions which consider the economic situation of future generations or enhance social and human capital achieved considerable integration but showed no inclination toward such conflicts.     

Towards a sustainable future: a holistic inquiry of waste management behaviors of Singapore households

ABSTRACT

In 2018, Singapore produced a 7.7 million tonnes of waste, which is a significant amount of waste for a small nation-state. In line with the Sustainable Development Goal (SDGs) targets 11.6 and 12.5 of the 2030 Agenda, which addresses cities’ waste generation and management impacts, we ask the question of why Singapore households are not more proactively engaged in waste minimization, despite the presence of local waste minimization public campaigns. This study is the first known study to comparatively apply and test three major theories – social psychological, social-structural, and sociocultural theories, to explain household waste management behavior in Singapore. A national survey followed by regression analysis of 303 households was conducted. In our findings, we firstly describe current trends in household waste management behaviors. Secondly, we compared each applied theory’s ability to predict households’: (1) reuse and (2) recycling of a variety of household items; and (3) recycling frequency. We obtained partial evidence supporting the role of future-orientedness and environmental identity on householders’ variety reuse and recycling. Social-structural (age cohort x income, education) and situational variables (the convenience thesis), also predicted various waste minimization behaviors. Finally, householders’ knowledge of what is recyclable affected all forms of waste minimization behaviors. In view of the study’s findings, we propose a need for targeted planning and policy interventions for different segments of the Singapore population, and different short- and longer-term measures to initiate and achieve sustained household waste minimization.
