Mark Bevan 《Housing Studies》2011,26(4):541-554
This paper reports research on people who live in housing that is defined as non-permanent by policy makers in England, and focuses on two particular groups: residents of park homes and residential boaters. The paper emphasises how the distinctive environments in which such housing is set may facilitate particular lifestyles, contributing to residents' identities. The notion of liminality is used as a framework to help understand the views of residents, highlighting the diversity of their experiences. Both park home residents and residential boaters ascribed a range of positive qualities to the environments in which they lived, underscored by the perception that the spaces that such accommodation occupied were often associated with leisure. Nevertheless, the nature of tenure relations in both settings potentially leads to vulnerabilities in the way that some people can maintain these lifestyles. These positive and negative facets were reflected in ambivalent feelings towards home both between groups of respondents and within individuals. 相似文献

为了探讨消费者生活方式与传统服饰文化在风格感知、自豪情感和意向行为间的影响关系,基于生活方式量表和传统服饰文化认同量表,提出了生活方式对中国传统服饰文化认同影响的研究模型。通过问卷调查,采用AMOS21.0和SPSS20.0对模型进行了验证,通过回归分析方法,进一步研究生活方式对文化认同各个因子的影响。研究结果表明:消费者生活方式对中国传统服饰文化认同有显著影响,追求时尚和偏爱传统的生活方式因子对传统服饰文化的意向行为影响显著,家庭事业、偏爱传统和价格敏感的生活方式因子对传统服饰文化的自豪情感影响显著,家庭事业、追求时尚和偏爱传统的生活方式因子对传统服饰文化的风格感知影响显著。不同类型的消费者对传统服饰文化认同有显著差异,重视传统的精英型对传统服饰文化认同度最高,缺乏兴趣的中庸型认同度最低。研究结果可供中式服装品牌和企业制定营销策略参考。 相似文献

In the present review, the association of out-of-home eating with anthropometric changes was examined. Peer-reviewed studies in eight databases were searched, and 15 prospective studies were included in the review. The quality of the data was assessed by considering risks of bias in sample selection, data collection methods, and the appropriateness of statistical tests. From this, seven studies, which used relatively large samples or had a follow-up period longer than 10 years, were retained for further analysis. It was concluded that eating out-of-home frequently, in the broad sense, is positively associated with the risk of becoming overweight or obese and weight change. With regard to specific out-of-home sources, the review shows that eating at fast-food outlets is associated with a greater increase in body weight and waist circumference over time than eating at restaurants and takeaway foods positively predict BMI change in women. More research is needed on out-of-home foods other than fast-foods and restaurant foods, such as street, canteen, and school foods. 相似文献

目的:探索北方地区成人脂肪肝的危险因素。方法:采用病例对照研究对294名病例和655名对照的相关资料进行非条件Logistic回归分析。结果:超重(OR=6.3,95%CI=4.4,8.9)、肥胖(OR=16.9,95%CI=9.9,28.9)、腹型肥胖(OR:2.9,95%CI=1.9,4.5)、血脂异常(OR=2.1,95%CI:1.5,3.0)及ST.T改变(OR=1.6,95%CI=1.0,2.3)与脂肪肝的患病明显相关(P〈0.05)。摄入肉类较多、高盐饮食及自觉压力较大均为脂肪肝的危险因素,其OR值分别为1.5(95%CI,1.0,2.1)、1.5(95%CI,1.1,2.1)及1.4(95%CI,1.0,2.2)。在家就餐超过5d为脂肪肝的保护因素,OR为0.6(95%CI,0.4,0.9)。结论:脂肪肝的发生与代谢性疾病及生活方式密切相关。 相似文献
