Is Tattooing a Risk Factor for Adolescents’ Criminal Behavior? Empirical Evidence from an Administrative Data Set of Juvenile Detainees in Taiwan

Juvenile crime affects not only the victims of the crime but also the delinquents’ future. How to prevent adolescent criminal behavior has become an important public policy issue. This study contributes to this interesting issue by examining the relationship between tattooing and adolescents’ criminal behavior. In particular, this study investigates whether or not having a tattoo/tattoos is connected to the incidence of various criminal activities, including: larceny, robbery, fraud, assault, drug use, and homicide. A unique sample of 973 juvenile detainees drawn from the administrative profiles in Taiwan and the coarsened exact matching method were utilized. Results show that compared to their nontattooed counterparts, tattooed juvenile detainees were significantly more likely to commit fraud, assault, drug abuse, and homicide by 3%, 13%, 9%, and 9%, respectively. In contrast, tattooing was not significantly associated with larceny or robbery. From a policy perspective, given the significant link between tattooing and criminal behavior, the presence of a tattoo in adolescents may serve as a valuable indicator regarding adolescents’ high probability of committing crimes.     

为《皆大欢喜》中的丑角试金石一辩

莎士比亚塑造了诸多耳熟能详的人物形象,《皆大欢喜》中的试金石是剧中的"丑角"。作为职业小丑,其幽默风趣随处可见。同时,他与村姑奥德蕾的感情、与忧郁旅人杰奎斯和牧羊人柯林的交流,展现出其幽默风趣外的另一面。分析试金石与三者之间的对话,总结变色龙般的试金石的独特"丑色",并进一步探索试金石"丑角"身份反映出的文艺复兴时期普通民众的心理诉求。     

利用伪随机信号系统辨识钻柱系统

用白噪声信号作为输入信号对钻柱系统脉冲响应进行辨识。研究了伪随机信号的特征及伪随机信号产生的方法,得出了用伪随机信号代替白噪声信号辨识钻柱系统脉冲响应的结论。结合输入信号和输出信号,利用钻柱系统的脉冲响应,讨论了钻柱的临界转速、钻柱共振、钻柱与井壁之间的相互作用、所钻地层岩性等钻井工程问题。     

On a system of nonhomogeneous components sharing a common frailty

The components of a reliability system subjected to a common random environment usually have dependent lifetimes. This paper studies the stochastic properties of such a system with lifetimes of the components following multivariate frailty models and multivariate mixed proportional reversed hazard rate (PRHR) models, respectively. Through doing stochastic comparison, we devote to throwing a new light on how the random environment affects the number of working components of a reliability system and on assessing the performance of a k-out-of-n system.     

伦理视角下农业的二重特性及农作“时”观念的省思

农业是人类生存和发展的基础和支撑,也是人类最早开始的有计划、有组织从事的社会活动。一方面,与其他人类活动不同,农业需要与大自然打交道,农业生产是在自然场所中显示和展开,自然亲自参与了农业生产的始终。另一方面,从对人类发展的推动来看,农业是人们最早为着满足自身生存需要而从事的一种社会活动。既然农业是作为人类的一种社会活动而存在,它必然体现了人的各方面社会特征和价值。与人参与其他社会活动涉及伦理一样,农业不但具有一般伦理的特性,而且因为它同时涉及人与自然的关系,于是决定了其伦理关注与其他人类活动不同,不只是关注人与人之间的伦理关系,更主要的是关注人与自然之间的伦理关系。农业关注的对象不是人,乃是有生命特性的农作物,这些农作物或者动物具备生命的类特征,而且这些生命特征出于自然,具有自然属性,这一点也决定了人在生产农作物的时候需要遵循自然的规范原则,由此亦决定了农业伦理需要在规范伦理学的框架中加以考察和认知。同时,农业是为着人类生存的需要而产生的,人对农业的判断又显示出功利性,使农业呈现功利性伦理的特征。因而,农业伦理具备了伦理学理论的各个层面,甚至将一些看似矛盾的伦理学理论恰如其分地整合在一起。农业伦理不只是单方面属于哪一个伦理理论,而是融合了伦理学中典型的两个流派即功利主义和义务论。在这种融合中,农业显明出一方面以支撑人的生存为目的,另一方面需要适应自然的客观性特征,于是农业伦理也随之在这两个层面反映出其独具特色的差异性。农业伦理的二重性不只是学理上的一种考量和认定,而且是具体地显明在农业实践之中,农业耕作中的"时"观念就是农业二重特性的实践显现,使农业伦理成为与具体实践相结合的实践理性。     

Do resources of network members help in help seeking? Social capital and health information search

Does social capital as resources of network members affect health information search? Analyzing data from the 2004 General Social Survey in the United States, this study measures two social capital indicators (average education of network members and proportion of network members with a high school degree or higher) using the name generator. Most results are consistent using those two indicators. Both indicators are positively associated with frequency of health information seeking and seekers’ frequency of use of two sources (friends or relatives and the Internet). Also average education of network members is positively associated with seekers’ diversity of used sources and frequency of consultation with medical professionals. But neither indicator is associated with seekers’ frequency of use of other four sources (health-related magazines or newsletters, general magazines, daily newspapers, and radio or television programs). The findings demonstrate the theoretical utility of social capital in the social dynamics of medical help-seeking.     

吉林省手风琴音乐创作的调查研究

目前,吉林省手风琴音乐的创作现状并不乐观,进行手风琴音乐创作的老艺人们大都年逾古稀,很多都已离世,只能从老艺人留下的历史资料或艺人们的口述中探寻当年吉林省手风琴音乐创作情况的蛛丝马迹.艺人们从事手风琴音乐创作的出发点除教学需要和个人兴趣之外,重要的一点是传承民族文化.要改善吉林省手风琴音乐创作的现状,一是要思考手风琴表演形式的创新,二是音乐创作素材的挖掘与思考.     

ＧＩＳ技术支持下的北宋初期丝路要道灵州道复原研究

在９世纪后半叶乃至整个１０世纪的丝绸之路东、中段交通网络系统中，灵州道占有一席之地。宋初，大食、回鹘、于阗以及归义军等民族政权多通过灵州道与北宋王朝进行经贸、文化往来。本文主要针对这一时段内灵州道的畅通情况及其道路性质进行探讨，在原有文献考证的基础上，利用考古资料、ＧＩＳ技术，尽可能实现对灵州道古地名数据的精确地理定位，最后使用ＡＲＣＧＩＳ技术，绘制灵州道的道路走向地图，为北宋灵州道区域的政治、经济、文化交流综合研究提供地理学依据。     

From advocacy to service provision: state transformation and the disability rights movement in Taiwan

This research uses the development of the disability rights movement in Taiwan as a case study to analyze the impact of state transformation, in particular marketization of social welfare policy, on the disability rights movement. First, the institutionalization of the disability rights movement enabled it to expand its organizational structure and become involved in shaping policy. Secondly, when disability rights organizations started to undertake state-funded projects, their focus shifted from advocacy to service provision. Thirdly, competition for limited state-funding gave the organizations led by urban-middle class advocates a significant advantage over small, community-based NPOs and gathered significantly greater resources. Finally, this paper suggests that, in a context in which the state did not provide basic social services for its citizens with disabilities, the institutionalization of SMOs turned advocacy groups into service providers. Although the number of disability civic organizations increased, the voices of advocacy groups were weakened.     

拥有自有品牌零售商的平台开放策略研究

随着电子商务的快速发展，零售商之间竞争加剧，自有品牌战略成为零售商获取竞争优势的关键。研究拥有自有品牌零售商的平台开放策略，通过对比零售商不开放平台和开放平台下的均衡利润，给出零售商平台开放策略选择条件，并分析产品之间价格影响系数、固定成本和潜在需求差异系数对零售商平台开放策略选择的影响，最后结合数值分析和京东自有品牌的发展现状验证了本文的主要研究结论。研究发现：第一，随着固定成本的增加，佣金费率逐渐减少，随着潜在需求差异系数的增加，佣金费率逐渐增加；第二，当产品之间的价格影响系数较小（较大）时，平台开放（不开放）是零售商的最优选择；第三，当固定成本较小（较大）时，平台开放（不开放）是零售商的最优选择；第四，当潜在需求差异系数较小（较大）时，平台开放（不开放）是零售商的最优选择。
