智利购房者对住宅建筑韧性的感知与支付意愿的研究

智利的住宅建筑不断遭受诸如地震等重大的自然灾害威胁。韧性是住宅建筑的关键属性,代表着抵抗,适应和从自然灾害中恢复的能力。住宅建筑的韧性水平受建筑的设计,施工和维护条件的影响,很大程度上决定了自然灾害发生时业主可能遭受的潜在损失。目前尚不清楚智利购房者对住宅建筑的韧性属性的了解程度如何,他们认为韧性在何种程度上是重要的,以及韧性对购房者购买决策是否有影响。为了研究这些问题,本研究首先对智利购房者的韧性意识进行了调查分析。对韧性意识的分析在两个维度上进行,包括购房者拥有的韧性相关知识以及他们对韧性重要性的感知。此外,本研究还通过问卷评估了购房者在房地产市场中作出购买决定时对住宅建筑韧性的支付意愿。该问卷调查的对象涵盖了智利不同地区的潜在购房者中,问卷对象的联系方式来自三家与房地产和建筑领域相关的全国性公司。问卷结果的分析表明,由于所掌握的建筑技术问题的知识有限,购房者对于部分影响韧性的关键因素的了解较为有限,但他们所感知的这些因素的重要性程度都很高。购房者认为的住宅建筑韧性的重要程度与其知识水平之间存在明显的差距。本研究设定了三种不同的购买情况,包括居住目的、投资目的、租赁目的。问卷结果显示,多达82.53%的受访者愿意支付额外的韧性财产。包括年龄、生活在目前居住处所的人数、目前是否拥有个人财产、当前住宅所有权的类型、是否在过去十年中经历过地震、是否曾在地震后修复住宅等诸多因素对受访者的韧性支付意愿有显著的影响。本研究结果表明,如果有机会在市场上购买韧性住房,且相关的韧性信息变得更加透明,那么智利的潜在购房者在做出购买决定时就不会无动于衷。此外,研究结果建议不同的利益相关方需要进一步努力来提升韧性意识,促进房地产市场的强韧性产品的发展,以及支持韧性信息透明的购买决策。

Objectives: Recent changes in life style have increased obesity, smoking and sedentary habits in the entire population. Obesity and overweight frequency have trebled in Mexico in the last few decades. The presence and frequency of cardiovascular risk factors were determined in students at the Universidad DeLa salle Bajío, both newly admitted and in advanced years. Material and methods: Anthropometric variables, serum glucose, total cholesterol levels, blood hemoglobin and hematocrit were obtained and assessed in 4814 students, 1507 recently admitted and 1507 advanced students. Results: The prevalence of obesity was 15.3%, sedentariness 33.8%, hypercholesterolemia 8.16%, smoking habits 15.8%, and alcohol consumption 12.1%. Body mass index (BMI) (23.5 ± 4 vs. 22.7 ± 4), waist/ abdomen index (0.84 ± 0.06 vs. 0.83 ± 0.06) and serum cholesterol (3.54 mmol/L ± 0.79 vs. 3.98 mmol/L ± 0.77) were greater in the advanced students
