煤矿作业人员安全心理特性模糊综合评价方法研究

根据模糊数学理论,将模糊综合评价方法引入煤矿作业人员安全心理特性评价。根据阜新矿业集团五龙煤矿的实际情况,建立了多层次煤矿作业人员安全心理特性评价体系,并且运用层次分析法确定评价因素的权重,最后结合安全等级表对模糊综合评价结果进行处理,得出煤矿作业人员的安全心理等级。     

安全文化宣教机理研究

为明晰安全文化宣教机理,从而提升安全文化宣教效果,基于宣传与教育的定义,提出安全文化宣教的定义,并分析其内涵。基于此,构建并解析安全文化宣教的“5-13”模式和受众处理安全文化符号信息的过程模型。在此基础上,提炼驱动受众心理的猎奇心理、重情心理与审美需要等16条理论依据和与之对应的一些具体方法。结果表明,设计、筹划和实施安全文化宣教活动和行为应以安全文化宣教的“5-13”模式和受众处理安全文化符号信息的过程模型为依据,有效驱动受众心理是提高安全文化宣教效果的关键。     

职业中毒场所盲目施救行为的心理因素分析与对策研究

探讨职业中毒场所因盲目施救引发伤亡事故扩大的原因及控制对策,为企业和相关部门实施有效的安全管理提供依据。采用分析归纳方法,界定盲目施救行为。依据突发事件引发的紧急情况的特点,分析得出有限作业空间发生的中毒窒息事故属于常规突发事件。盲目施救导致伤亡扩大事故发生的主要行业和作业特性显示,安全监管的疏漏是事故发生的原因。根据社会心理学理论,对中毒人员的施救属于利他行为,盲目施救是人在应激状态下失控的冲动行为,这一行为与人对不安全行为的预期后果相关,应急知识和能力的缺乏是导致盲目施救行为发生的主要原因。根据上述研究结论,提出避免常规突发事件引发盲目施救行为的对策。     

Incorporating basic needs to reconcile poverty and ecosystem services

Conservation managers frequently face the challenge of protecting and sustaining biodiversity without producing detrimental outcomes for (often poor) human populations that depend on ecosystem services for their well-being. However, mutually beneficial solutions are often elusive and can mask trade-offs and negative outcomes for people. To deal with such trade-offs, ecological and social thresholds need to be identified to determine the acceptable solution space for conservation. Although human well-being as a concept has recently gained prominence, conservationists still lack tools to evaluate how their actions affect it in a given context. We applied the theory of human needs to conservation by building on an extensive historical application of need approaches in international development. In an innovative participatory method that included focus groups and household surveys, we evaluated how human needs are met based on locally relevant thresholds. We then established connections between human needs and ecosystem services through key-informant focus groups. We applied our method in coastal East Africa to identify households that would not be able to meet their basic needs and to uncover the role of ecosystem services in meeting these. This enabled us to identify how benefits derived from the environment were contributing to meeting basic needs and to consider potential repercussions that could arise through changes to ecosystem service provision. We suggest our approach can help conservationists and planners balance poverty alleviation and biodiversity protection and ensure conservation measures do not, at the very least, cause serious harm to individuals. We further argue it can be used as a basis for monitoring the impacts of conservation on multidimensional poverty.     

汶川地震后幸存人员心理危机干预方法研究

选取汶川地震中的伤员和陪护家属各40人作为干预对象,采用心理治疗中的心理危机干预方法,对干预对象进行心理危机干预。干预过程分为3个阶段,分别是以构建良性关系为目的的初始阶段、以治疗为核心的干预和稳定阶段、以评估干预效果为目的的评估阶段。干预评估结果显示,心理危机干预前后,伤员和陪护家属评估结果存在显著差异（P<0.001）;与语言方法相比,该研究方法进行心理危机干预后,各量表得分显著下降,症状自评量表各评估方向得分显著低于语言方法的量表得分,前、后侧得分间差异存在统计学意义,说明该方法心理危机干预对震后人员恢复,效果较好。     

An assessment of the environmental and socio-economic impacts of alien rabbits and hares

Directly comparable data on the environmental and socio-economic impacts of alien species informs the effective prioritisation of their management. We used two frameworks, the Environmental Impact Classification for Alien Taxa (EICAT) and Socio-Economic Impact Classification for Alien Taxa (SEICAT), to create a unified dataset on the severity and type of impacts caused by alien leporids (rabbits and hares). Literature was reviewed to collate impact data, which was categorised following EICAT and SEICAT guidelines. We aimed to use these data to identify: (1) alien leporid species with severe impacts, (2) their impact mechanisms, (3) the native species and local communities vulnerable to impacts and (4) knowledge gaps. Native species from a range of taxonomic groups were affected by environmental impacts which tended to be more damaging than socio-economic impacts. Indirect environmental impacts were particularly damaging and underreported. No impact data were found for several alien leporid species.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13280-021-01642-7.     

It is all about the bottom line: Group bottom-line mentality,psychological safety,and group creativity

We examine bottom-line mentality (BLM) at the group level and examine the effect of group BLM on group psychological safety and subsequent group creativity. We draw on goal shielding theory to suggest that groups high in BLM narrowly focus on bottom-line outcomes, which encourages them to eliminate distracting considerations from their work processes. Because the group's high BLM encapsulates goal shielding, these groups are deficient in fostering psychological safety as an important interpersonal process that facilitates group creativity. We also couple goal shielding theory with arguments related to situational strength to examine group BLM agreement (i.e., the standard deviation of the mean of group BLM) as a first stage moderator. We contend that high-BLM agreement (vs. low agreement) strengthens the goal shielding effect of group BLM, which is reflected by a stronger detrimental effect on group psychological safety that then reduces group creativity. We found support for our theoretical model using multisource, multiwave field data from a diverse sample of workgroups and their supervisors. We discuss the theoretical implications of our research and provide practical suggestions for limiting the deleterious consequences of group BLMs in the workplace.     

基于人员心理-环境因素的火灾疏散速度修正方法研究

为探究人在火灾环境下的行为心理对疏散效率的影响,基于火灾下人员行为心理特征具有复杂、抽象、难以直接量化的特性,通过模糊逻辑方法,应用模糊集合、模糊规则和隶属度函数量化人的行为心理,研究其对疏散速度的影响;考虑火灾烟气和群体行为对疏散的影响,通过对高层建筑火灾状况下的烟气进行数值分析,并运用公式法得出人员的疏散速度折减值;以某高层商业建筑火灾疏散为例,将修正后人员的疏散速度和疏散路径引入疏散分析并与未修正的结果进行比较。结果表明:未修正的商业建筑疏散时间为470 s,修正后的疏散时间为670 s,修正后的疏散时间更长,人员危险性更大。     

可持续发展研究的3个关键课题与中国转型发展

从数量扩张的增长模式转向质量提升的发展模式,是中国未来30年转型发展的核心问题.本文介绍了20世纪90年代以来可持续发展在3个关键课题上的研究进展.在经济增长与社会富祉的关系上,指出经济增长对于社会富祉的贡献存在着门槛,跨过这个门槛经济增长对福利贡献的边际效用开始递减;在经济增长与资源环境的关系上,指出经济增长没有导致资源环境消耗的倒U型曲线,在自然资本存在限制的情况下无限的经济增长是不可能的;在政府支出与民生发展的关系上,指出公共支出增大并不必然导致社会福利的提高,而公共支出的结构与方式对民生发展却是极其重要的.在对每个问题分析事实依据、原因解释、政策意义的基础上,针对中国转型发展提出了一些具有长期意义的理论思考与政策思考.
