利用国家重点研发计划重点专项2018年调研数据,构建了自然灾害冲击对农村家庭非农就业选择影响的理论框架,采用Probit模型验证了自然灾害冲击对农户家庭成员非农就业选择的影响。研究发现:自然灾害冲击对农户家庭成员非农就业选择有显著正向影响,这一正向影响会随着自然灾害强度的增加而不断提升;人力资本和社会资本的嵌入,会弱化自然灾害对农户家庭成员非农就业选择的影响,信贷约束却会强化这一影响。这意味着现阶段面对自然灾害冲击,农户家庭成员应积极尝试非农就业,不仅能够促进资本存量重构,还可以缓解家庭生计压力,增加农户家庭收入,避免农户家庭因灾致贫。  相似文献

王守仁的儿童自然教育思想是以“明人伦”的教育目的、“心即理”的心学理论作为其思想的基础,结合自身的教学经验总结形成的思想理论体系。他以树为喻,认为儿童的教育要遵循自然规律,这在当时具有先进性和科学性。本文主要通过解读王守仁的自然教育思想,即教育要顺应性情,因材施教,注重独立探索等。其思想对当今幼儿家庭教养方式的启示为:清晰认识儿童,把握自然生长规律;随人分限所及,对儿童有适度期望;尊重而非压制,创造和谐家庭氛围;注重德行习惯,促进儿童全面发展;重视潜移默化,言传身教树立榜样;着重实践探索,锻炼儿童独立思考。  相似文献

Previous research has evaluated public risk perception and response to a natural hazards in various settings; however, most of these studies were conducted either with a single scenario or after a natural disaster struck. To better understand the dynamic relationships among affect, risk perception, and behavioral intentions related to natural disasters, the current study implements a simulation scenario with escalating weather intensity, and includes a natural experiment allowing comparison of public response before and after a severe tornado event with extensive coverage by the national media. The current study also manipulated the display of warning information, and investigated whether the warning system display format influences public response. Results indicate that (1) affect, risk perception, and behavioral intention escalated as weather conditions deteriorated, (2) responses at previous stages predicted responses at subsequent stages of storm progression, and (3) negative affect predicted risk perception. Moreover, risk perception and behavioral intention were heightened after exposure to the media coverage of an actual tornado disaster. However, the display format manipulation did not influence behavioral responses. The current study provides insight regarding public perception of predisaster warnings and the influence of exposure to media coverage of an actual disaster event.  相似文献

民族学经过一个多世纪的探索,逐步地达成了一个共识,建构一种文化并不是一件轻而易举的事情。文化是指导人类生存发展延续的信息系统,文化的建构是以所处自然生态系统为底本,以并存的社会生态系统为参照,文化这一信息系统不断偏离与回归所处自然生态系统与社会生态系统,在世代延续过程中逐步认知、积累其成败的经验与教训,并在传承的过程中不断地完善和丰富起来。民族以文化为分野,不同民族所处自然环境与社会环境互有差异,这就形成了民族生境的差异性,而民族生境的差异性也同样会建构出不同民族文化事实体系的差异性来。  相似文献

Placement of refugees and subsequent labour market integration within a host country represents a key challenge for policymakers and has emerged as one of the most divisive topics in the public debate. Immigration policy in Switzerland adopts random placement of asylum seekers across its different language regions. Hence, this policy allows to estimate the causal effect of language skills on employment chances, as refugees are exogenously placed across regions where the spoken language could either match or deviate from individual language skills. The results of this ‘natural experiment’ indicate substantially higher probabilities of finding employment when asylum seekers are placed in regions with a lingua franca that matches their individual language skills. Additionally, the findings suggest that language course participation can offset the reduced likelihood of employment in cases of a language mismatch. While random placement of refugees may be desirable for political reasons, it is detrimental to the economic integration process. Thereby, the study draws relevant conclusions for a larger European immigration policy.  相似文献

Many studies have examined the general public's flood risk perceptions in the aftermath of local and regional flooding. However, relatively few studies have focused on large‐scale events that affect tens of thousands of people within an urban center. Similarly, in spite of previous research on flood risks, unresolved questions persist regarding the variables that might influence perceptions of risk and vulnerability, along with management preferences. In light of the opportunities presented by these knowledge gaps, the research reported here examined public perceptions of flood risk and vulnerability, and management preferences, within the city of Calgary in the aftermath of extensive flooding in 2013. Our findings, which come from an online survey of residents, reveal that direct experience with flooding is not a differentiating factor for risk perceptions when comparing evacuees with nonevacuees who might all experience future risks. However, we do find that judgments about vulnerability—as a function of how people perceive physical distance—do differ according to one's evacuation experience. Our results also indicate that concern about climate change is an important predictor of flood risk perceptions, as is trust in government risk managers. In terms of mitigation preferences, our results reveal differences in support for large infrastructure projects based on whether respondents feel they might actually benefit from them.  相似文献

ABSTRACT

Drawing on my experience as a queer, genderqueer, Puerto Rican counselor educator, this article considers how LGBTQAI+ studies and academia can expand to better include people with multiple marginalized identities. This article highlights some of the contradictions that educators face when engaging in the liberatory praxis that connects and creates a sense of belonging during these tumultuous times. This reflection suggests a decolonizing approach to intersectionality and highlights the importance of transcending binary discourse to engage in deconstructing the multiple layers of colonization in our internal and external spaces that is necessary for liberatory praxis. Finally, a few recommendations for how LGBTQAI+ studies and academia can support scholars with multiple marginalized identities are identified.  相似文献

This article presents methodological solutions aimed at presenting the spatial distribution of flood risk and quality of spatial management (land use), indicating both those areas used reasonably and those requiring modification. The purpose was to identify key risk areas and risk‐free areas from the point of view of human security and activity on the floodplains, based on the examples of the vicinities of Wroclaw and Raciborz in the Odra Valley, Poland. Due to recent climate change, Poland has suffered the effects of severe flooding (e.g., 1997, 2001, 2010). The analyses conducted were motivated by the European Parliament and Council's recently implemented Directive 2007/60/WE, as well as by the demand for studies for local spatial planning. The analysis indicates that reasonably developed areas do not account for the majority of those studied, making up 36% of the Wroclaw area and 15% of the Raciborz area.  相似文献
