家庭结构与健康风险:基于青少年近视的实证分析

家庭结构与青少年发展关系密切,但鲜有研究注意到其对身体健康的影响。本研究以近视为例,强调独生子女带来的亲子唯一性和强势社会化对我国青少年身体健康的影响,以及家庭居住安排不同带来的条件叠加效应。基于CEPS数据的分析表明,独生子女近视几率显著高于非独生子女;居住安排对独生子女是否近视没有影响,但会显著改变非独生子女近视的几率。在控制其他变量的情况下,这种效应的大小虽有所下降但仍显著存在。因此本研究认为,家庭结构变迁,特别是独生子女家庭增多也是近几十年来我国青少年近视率不断增高的社会原因。未来研究应就此进行更加丰富的探索,厘清其中的作用机制,从社会科学的角度为全国性的近视防控提供更多依据。     

文化中介者与“驴友”旅游品味的建构——基于《孤独星球》的内容分析

如同其他品味制造者一样,《孤独星球》作为将出版商和"驴友"连接起来的旅游攻略,可以被延伸为布迪厄语境下的文化中介者,它通过调适旅游目的地与旅游实践和旅游品味的关系而建构、形塑着"驴友"的品味。在对目前《孤独星球》中国系列丛书进行词频统计和社会网路分析可视化后,发现其从景点、住宿、交通、饮食四大模块构建了"驴友"追求自然本真、刺激冒险、"异文化"风情、节俭环保、"文艺范"和重视体验的一套符合"驴圈"的身份认同的旅游品味,从而区分"驴友"与其他旅游者的关系,最终构建了旅游品味的合法性权威。

艾滋病人卖淫嫖娼行为的刑法评价

艾滋病群体属于特殊的弱势群体。卖淫、嫖娼行为则常常为道德所不耻,在中国法律体系中,一般属于行政违法行为。特殊主体与一般违法行为的不当结合,产生了严重危害社会的结果,也使其进入了刑法的视野。但是对这一行为在刑法上应当如何评价,在理论和实务中却存在着各种争论与冲突。总结各种观点,大多认为其可能构成传播性病罪、故意杀人罪、故意伤害罪。当然也有学者提出增设传播艾滋病毒罪的主张。笔者则认为该类行为宜认定为危害公共安全罪。     

Europe Likely to Become the Second Largest Offshore Market for the Yuan

跨地域语境中台湾电影的台湾形象建构与迁化

跨地域语境下台湾电影中的台湾形象是中国形象的区域性建构与想象。台湾电影中的台湾形象总是置身于"中国大陆—台湾—日本"和"中国大陆—台湾—美国"的"文化三角"模式中,并以一个相对于"父"的"子"形象被加以建构和塑模。台湾历史性地纠结于我性的祖国之"母"、"宰制之父"(清政府和国民党当局)和"传统之父"与他性的"殖民之父"(日本)和"西方之父"(美国)所形成的文化"夹缝"中,表现为悲情"弃子"和现代"游子"的演变。台湾形象中强烈的主体意识、浓郁的文化乡愁和历史的无家焦虑之间的冲突,凸显了中国国家形象中最为纠结和最为繁复的特殊景观,昭示了想象和建构的艰巨性。     

Portable high‐resolution automated 3D imaging for footwear and tire impression capture

The forensic science community raised the need for improved evidence recognition, collection, and visualization analytical instrumentation for field and laboratory use. While the 3D optical techniques for imaging static objects have been extensively studied, there is still a major gap between current knowledge and collecting high‐quality footwear and tire impression evidence. Among optical means for 3D imaging, digital fringe projection (DFP) techniques reconstruct 3D shape from phase information, achieving camera‐pixel spatial resolution. This paper presents a high‐resolution 3D imaging technology using DFP techniques dedicated to footwear and tire impression capture. We developed fully automated software algorithms and a graphical user interface (GUI) that allow anyone without training to operate for high‐quality 3D data capture. We performed accuracy evaluations and comparisons comparing with the commercial high‐end 3D scanner and carried out qualitative tests for various impressions comparing with the current practices. Overall, our technology achieves similar levels of accuracy and resolution with a high‐end commercially available 3D scanner, while having the merits of being (1) more affordable; (2) much easier to operate; and (3) more robust. Compared with the current practice of casting, our technology demonstrates its superiority because it (1) is non‐destructive; (2) collects more evidence detail than casts, especially when an impression is fragile; (3) requires less time and money to collect each piece of evidence; and (4) results in a digital file that can easily be shared with other examiners.     

Stable Growth Can’t Overly Rely on Stock and Housing Markets

<正>While people are fixing their eyes on the capricious stock market,the housing market receives less attention.Currently,the housing market in first-tier cities is robust or undergoing a turnaround,but most second-tier cities and almost all third-and fourth-tier cities still frown upon their sluggish commercial housing sales.     

China's Approach to BRICS

The economic rise of the BRICS (Brazil, Russia, India, China and South Africa) inevitably leads to a redistribution of power in the international system. Chinese leaders today accord a considerable priority to this group, and there are elements of realism, liberalism/institutionalism and constructivism in their approach. This article intends to study China's policy towards BRICS and examine the above elements so as to better understand how the Chinese leadership perceives China's role in the international system, and how it seeks to articulate its interests and enhance its influence.
