撬动社会资源： 公益创投评估与SROI实证应用

公益创投项目撬动了社会善的力量,为完善政府与社会协作机制提供了经验,但政府在项目考核时缺乏客观完善的评价指标。由“外来务工人员和困难家庭子女帮教助学项目”和“‘折翼天使’圆梦项目”的具体分析可知,社会投资回报(SROI)分析方法不仅有利于衡量公益创投项目的可持续发展能力,还有利于政府通过绩效评估更加深入地了解弱势群体的实际需要,并据此完善相关工作。基于公益创投项目的运作情况,组织背景、项目目标、受助群体弱势程度的不同都可能影响到项目运行的绩效结果,政府应在现有评价指标中加入对投资回报的测算,并通过公益创投分析项目属性,进行针对性帮扶,同时加强对公益创投项目的过程监测以及基础数据库建设,实现社会资源效用的最大化。

Intergenerational Mobility Modes and Changes in Social Class in Contemporary China

Using data from three China General Social Surveys, this paper analyzes changes in the basic situation of intergenerational mobility among social classes in China over the past 60 years. General social mobility was found to have increased, but social openness tended to show a wave-like pattern of change. Despite this, intergenerational inheritance was the main form of intergenerational mobility in every period. With the transformation of the socioeconomic system, the main mechanism of social exclusion changed from “systemic exclusion” to “market exclusion,” leading to changes in the structure of social opportunity. As a result, the form taken by intergenerational mobility varied significantly. This is chiefly evident in the gradual decline in the dominance of intergenerational inheritance among particular strata, with cross-class cyclical mobility becoming more difficult. On the one hand, changes in the social exclusion mechanism may increase social openness, making society more dynamic and strengthening social legitimacy. On the other hand, as the dominant class learns how to use market exclusion to achieve class reproduction, class solidification may still be possible in a future Chinese society.     

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.     

论老年人犯罪从宽暨免死的年龄标准与立法模式——以《刑法修正案(八)》为视角

老年人犯罪从宽的年龄标准应当有别于老年人免死的年龄标准。当前,中国对老年人犯罪从宽的年龄宜规定为"年满70周岁",而对老年人犯罪免死的年龄则宜规定为"年满75周岁"。对老年人犯罪从宽应当与对未成年人犯罪从宽相一致,统一规定为"应当从轻或者减轻处罚",而没有必要区分故意和过失犯罪分别规定。考虑到老年人犯罪免死的根据、刑罚目的和国际上的普遍做法,中国应当免除所有老年人犯罪的死刑,而不应有例外。     

汉语不平等同义并列式双音词研究

目前,语法学界对汉语同义并列式双音词构词法的分析只到"并列"为止,没有进一步深入探讨这两个语素是怎样的并列状态。笔者认为同义并列式双音词的两个语素地位并不是绝对平等的,据此,可以把不平等同义并列式双音词分为三种类型———后限定式、前限定式、附加式。前、后限定式的不平等同义并列分别与偏正、动补结构在表意上具有相同的作用,这种跨结构的表意上的一致性,归根到底是为了适应汉语双音化和表意精确化的要求。
