Cultural change is critical to climate change responses, but the in-depth qualitative research that investigates culture is necessarily conducted at scales difficult to integrate with policy. A focus of climate change mitigation and adaptation is affluent developed world households. Adapting methods used elsewhere in social science, we report and assess a meta-ethnography of household sustainability research, scaling up findings from 12 studies encompassing 276 Australian households. Seven themes are dominant: family concerns are central to household practice; adaptiveness is contingent but more pervasive than often assumed; households make sense of climate change not through abstract arguments, but through physical resources and materials; boundaries of the home space are dynamic and subjective; daily time is an important currency; paradoxes abound among everyday practice; and privacy and a sense of autonomy are prioritised. Insights from the method include new light on familiar themes when seen through an environmental lens, thickening and triangulation of existing research, and a stronger basis for international comparisons. Some findings have straightforward application to policy, others identify potential areas of risk and resistance, others still are more conceptual. We conclude the method has considerable potential and is worth developing further, providing a critical perspective is maintained.  相似文献

Scholars have noted that race and ethnicity, socio-economic status (SES) as well as other socio-demographic factors may limit participation in local food systems based on the historic and structured patterns of inequalities that remain in communities promoting alternative agriculture and food (agrifood) activities. However, few empirical studies have examined the barriers which prevent people from participating in local food system activities. This paper uses survey data from the 2008 Ohio Survey of Food, Agriculture and Environmental Issues to consider whether barriers such as interest, time, financial resources, geography and space impact the participation of households in home gardening. Results from logistic regression show that SES, the availability of space and housing type are important factors which limit or enable household participation in home gardening. This paper contributes to our understanding of the barriers that prevent households from participating in home gardening, a form of food system localisation that, while a potentially powerful way to transform the agrifood system, has been underexamined in its own right.  相似文献

Exploring the role of both the employee and supervisor, we tested a model of how cognition‐based work‐to‐family conflict manifests itself in the workplace, impacting employee job success. Based on conservation of resources theory and the concept of loss spirals, we hypothesized that when an employee's work interferes with family demands, the resulting work‐to‐family conflict spills over to the work domain via employee emotional exhaustion. We further argued that the behavioral manifestation of employee emotional exhaustion in the workplace is low employee engagement, as assessed by the supervisor. Drawing on signaling theory, we proposed that supervisor assessments of employee engagement are related to promotability, performance ratings, and salary. Work scheduling autonomy, as a boundary condition, is examined as a resource that attenuates these relationships. Data collected from 192 employee–supervisor dyads of a Fortune 1000 company, as well as performance ratings and salary obtained from company records 9 months later, indicated support for our conceptual model. Future research examining employee work–family conflict and job outcomes is discussed. Copyright © 2016 John Wiley & Sons, Ltd.  相似文献

Social vulnerability indicators can assist with informing disaster relief preparation. Certain demographic segments of a population may suffer disproportionately during disaster events, and a geographical understanding of them can help to determine where to place strategically logistical assets and to target disaster‐awareness outreach endeavours. Records of house fire events and American Red Cross aid provision over a five‐year period were mapped for the County of Los Angeles, California, United States, to examine the congruence between actual events and expectations of risk based on vulnerability theory. The geographical context provided by the data was compared with spatially‐explicit indicators of vulnerability, such as age, race, and wealth. Fire events were found to occur more frequently in more vulnerable areas, and Red Cross aid was found to have an even stronger relationship to those places. The findings suggest that these indicators speak beyond vulnerability and relate to patterns of fire risk.  相似文献

个人特征、家庭特征对农村非农就业影响的实证   总被引:3,自引:0,他引:3  
工业化对于一个国家或地区经济腾飞的重要性,已经被西方发达国家的经验和道路所证实。在实现工业化的过程中,农村劳动力转移是世界各国都曾经或必将面对的重要课题。本文运用行为主义研究方法,利用2003-2006年全国农村固定观察点的数据,建立Probit模型实证分析了农民个体特征和农户家庭特征对农村非农就业的影响。研究发现:就样本个人特征而言,户主或家庭主要经营者、男性、文化程度较高、身体健康的农民从事农村非农就业的意愿更强,职业教育或培训对于农村非农就业有明显的促进作用,而是否农业户口对农村非农就业的影响并不明显。就样本家庭特征而言,家庭类型会影响农民在农村的非农就业倾向,同时,乡村干部户从事非农产业的倾向性更强,少数民族户和信教户从事非农产业的倾向性较弱,"是否国家干部职工户"、"是否党员户"对农村非农就业的影响并不显著。重视农民的个人特征和家庭特征差异,大力发展农村非农产业,促进农村非农就业是我国政府解决农村剩余劳动力转移问题的重要战略选择。  相似文献

This study examined the factors associated with financial support in old age from three primary mechanisms-personal savings,family support,and social insurance-to explore the implications for the future development of China’s rural social welfare system.Cross-sectional surveys of 1392 young and middle-aged rural residents were conducted in July and August2012.The results showed that while social insurance was increasingly acceptable,personal savings and family support still had fundamental value.Combining the three mechanisms,the rural old-age welfare system presented nontraditional features.China’s new rural endowment insurance is discussed as a means to address the need for financial support among the rural aging population.  相似文献

为建立适用于我国高层民用住宅特点的紧急疏散模型,为评价高层住宅建筑安全性、指导人员逃生提供科学依据。通过问卷调查和实际观测,分析家庭疏散对象的心理特征,对传统紧急疏散模型进行优化,提出以家庭为单位的集群紧急疏散模型,并进行仿真。仿真模型以社会力模型为基础,通过分析和计算家庭内部成员与外部人员2种不同的"社会心理力",进而体现集群疏散的宏观特征。仿真结果分析了家庭集群疏散与传统紧急疏散,这2种情况下主要交通参数的差别,论证了家庭集群疏散模型的科学性和合理性。  相似文献

Research was conducted in Nottinghamshire, England to investigate public attitudes regarding home energy efficiency issues. Quantitative data were collected in the form of a postal survey, achieving over three hundred responses. Additionally, predominantly qualitative data were collected in semi-structured interviews in 15 homes. The issues investigated included the grant-funded energy efficiency measures installed by the public, the organisations providing grants, the means by which the recipients were referred to the organisations, and the public's preferences regarding energy efficiency advice. Findings were made about the local authority's success in encouraging the take-up of energy efficiency grants, about the public's preferences for the means by which advice should be provided, about trust relating to energy efficiency grants provided by gas and electricity suppliers, and about people's knowledge of the most effective energy efficiency measures. Additional findings were drawn about specific energy efficiency issues, including old heating systems and compact fluorescent light bulbs.  相似文献

It appears that in most Western countries, son preference is somewhat stronger than daughter preference. However, when one considers the preference of women it looks as though the opposite pattern is emerging. There is a considerable social acceptance of ‘light’ methods of sex selection (such as diets), even though these methods are not proven to be effective. The inclination to use sperm separation methods appears to be greater in the United States than in some European countries. There are indications that a preference for boys or for girls is associated with attitudes towards technology, child-rearing style and the stereotyping of boys or girls.
