We provide experimental evidence on the effect of peer pressure on individual behavior. Specifically, we study the effect of being exposed to an observer in a public restroom on handwashing and urinal flushing behavior. Our estimates show that being exposed to an observer increases the probability of handwashing by 13 percentage points and the probability of urinal flushing by 15 percentage points. Given that handwashing and urinal flushing have social benefits that exceed individual benefits, our findings provide support for peer pressure as an additional way of addressing the social suboptimality arising from externalities.

Objectives: To assess sex hormones, leptin and insulin-resistance in men with prostate cancer (PCa) and benign prostatic hyperplasia (BPH) and to study associations between androgens and histologic score of prostate tissue in PCa.Subjects and methods: Two hundred ten men older than 45 years selected from 2906 participants of a population screening for PCa were studied: 70 with PCa, 70 with BPH and 70 controls (CG), matched by body mass index and age. Insulin, IGF-1, PSA, leptin, total, free (fT) and bioavailable testosterone (bT) and estradiol were measured. Each group was subdivided into two subgroups considering the presence of metabolic syndrome (MS); androgens and leptin levels were analyzed in the subgroups.Results: Prostate cancer and BPH patients presented higher total, fT and bT levels than CG. IGF-1, insulin and HOMA index were higher in BPH than in the other two groups. PCa presented higher leptin [median (range) 6.5 (1.3–28.0) versus 4.8 (1.1–12.3) ng/ml; p?0.01] and estradiol [median (range) 37.0 (20–90) versus 29.0 (20–118) pg/ml; p?=?0.025] levels than CG. After dividing men considering the presence of MS, leptin was higher and total testosterone was lower in MS patients in all the groups.Conclusions: It was observed a coexistence of an altered hormone profile with increased sex hormones and leptin in PCa patients, in accordance with the new perspective of PCa pathogenesis. 相似文献

The digital Silk Road, which involves the internationalization of Chinese internet firms across countries that are party to the Belt and Road Initiative (BRI), has remained underexplored in the literature. This paper employs a poststructuralist discourse theory to analyze one of the most important Chinese internet firms, Alibaba, and its initiative for global trade: the electronic World Trade Platform (eWTP). The article argues that the eWTP is a counter-hegemonic discourse that, based on the economic and technological power of Alibaba and its support of the BRI, attempts to globalize a China-centered and privately led global digital trade order to challenge the previous wave of US-led globalization. However, the eWTP has at least five contradictions. First, despite its criticisms of globalization, the initiative remains essentially neoliberal. Secondly, it sidelines inherent tensions with the Chinese state-centric internet governance model. Thirdly, it excludes some social identities and makes utopian promises. Fourthly, it is unclear to what extent it really will be inclusive. Finally, unless carefully hedged, it might entrap partner countries in new types of problematic digital dependence. 相似文献

Ergonomics and design for sustainability in healthcare: ambient assisted living and the social-environmental impact of patients lifestyle 总被引:1,自引:0,他引:1
This work presents considerations on Ergonomics and Design for Sustainability in the healthcare field based on research experiences of the Technology and Design for Healthcare (TeDH) research group of INDACO (Industrial design, communication, arts and fashion) department of Politecnico di Milano. In order to develop a multidisciplinary approach to design able to answer to specific user needs such as elderly in an environmental sustainable way (1) this paper shows the results we achieved concerning ergonomics and environmental impact in product development (2), the extension of this approach to interior and home design and the advantage of the application of Information Communication Technologies (ICT). ICT can help people with special needs to make their everyday life easier and more safe, at the same time, ICT can make social-environmental impact of everyday behavior evident and can be applied to manage sustainability. The specific theme is thus to integrate ergonomics and sustainability competences in the development of Ambient Assisted Living through a Product- Service System approach. The concept of product service system has the potential to improve product performances and services, establish new relations and networks with different actors in order to satisfy user needs and apply a systems approach considering environmental, social and economic factors in the users' environment. 相似文献
