Modeling Demand For Unionization With Nontraditional Data Analysis Methods

Upon reviewing the extant literature on determinants of unionism, it becomes clear that many areas that have had a plethora of research attention do not converge upon singularly directional findings. This study explores a potential cause of such an apparent anomaly: nonlinearity of data. An exploratory examination of correlation coefficients among typical union determinant variables seems to show different patterns of relationships at different levels of union demand. Thus, a break from traditional linear data analysis techniques is explored in the interest of explaining more variance with typical, theoretically derived variables by using neural network analysis. Results of analyses on industry level data reveal that using neural network analysis to model union demand explained over four times as much variance as multiple regression analysis.     

Disagreement over the immigration of low-income earners in a welfare state

This paper studies natives’ economically motivated preferences over different levels of immigration of low-income earners. Immigration affects natives through both intra- and intergenerational redistribution programmes and in the labour market. Our analysis suggests, in a welfare state that looks after the poor and the aged, economic motivation does not necessarily lead a native to have an extreme opinion on the preferable level of immigration, although it causes disagreement among natives. We find, regardless of parameter values, high-income earners prefer at least as much immigration as low-income earners who, in turn, prefer at least as much immigration as pensioners. The median voter is then likely to be a low-income native.

论色彩设计的回归

现代设计之后的设计思想与实践不仅从环保的、生态的角度积极探讨研究通过设计建立新型的人与自然的和谐共生关系,而且尊重不同的文化,弘扬人文主义精神,并且取得了许多成就。但色彩设计作为现代设计中的重要因素,从设计理论研究和实践应用两方面都还存在不足。文章立足于色彩和色彩设计的本质属性,对色彩和色彩设计的概念、现象及应用进行反思和再认识,主张色彩设计应回归自然本质和人文精神的体现,并在色彩设计中建立系统观念,更好地对色彩设计进行定位。这样才能满足现代设计发展的需要,发挥色彩设计更大的作用。     

中韩出口产品的竞争程度分析

中国的出口将对周边国家包括韩国带来深远影响。中国和韩国的产品出口是否存在竞争关系,如何衡量中韩产品出口的竞争程度,是我们试图研究的主要问题。我们通过按技术构成对产品进行分类,并借鉴关志雄和Lall等人计算产品附加值的方法,比较分析了中国和韩国自20世纪80年代后期以来出口商品的结构变化。结果表明:中国和韩国的产业竞争程度并非表面显现的那么高,中国和韩国可以在国际分工的不同生产环节实现优势互补。     

儿童友好型城市视角下费城游戏学习景观的实践探索与经验借鉴

以费城“游戏学习景观”项目为例,从项目的发展历程、实践的理论、设置类型三个方面对“游戏学习景观”进行探析,提出费城基于儿童友好型城市视角下建设游戏学习型城市的经验借鉴：社会各界的领导者积极推动实施游戏学习景观倡议;建立互相包容合作的战略伙伴关系;注重对项目数据的收集、监测和评估;重视宣传引导,形成全社会对游戏重要性的认识和实践。     

中国老年人的主观年龄及影响因素分析

随着中国老龄化进程的加快,越来越多的研究开始探讨老年的定义和标准,但很少有研究直观地描述和分析老年人对自身进入老年的年龄标准的看法以及其主观年龄的差异。本研究使用2014年至2018年中国老年社会追踪调查的三期数据,比较分析不同队列在不同实际年龄(日历年龄)下认定的自身进入老年的年龄标准的变化以及不同实际年龄老年人的主观年龄的差异。数据分析结果显示受访者自我认定的老年的年龄标准平均为70岁,远高于社会上通常认定的60岁或65岁的标准;主观年龄和主观外表年龄平均在68岁左右,低于受访者的平均实际年龄(71岁),超过六成的受访者的主观年龄与主观外表年龄比实际年龄“更年轻”。进一步的统计模型分析结果显示健康状况越好、与子女同住、有广泛的朋友支持网络以及更愿意参与村居委会投票的老年人所认定的自己进入老年的年龄标准也更高。更多的社区娱乐场所或设施和室外活动场地也能显著地提高受访者认定的进入老年的年龄标准。更高的受教育程度以及更好的健康状况是促使老年人的主观年龄和主观外表年龄小于实际年龄的重要因素。本文直观地描述了不同实际年龄的老年人所认定的自身进入老年的年龄标准以及其主观年龄与实际年龄的差异,为与年龄相关的老龄政策的制定提供了参考。     

关注家庭文明建设提高家长教育素质--评骆风《造就卓越人才-北京大学博士生家庭教育探析》

近20年来,特别是中共十四届六中全会发布《中共中央关于加强社会主义精神文明建设若干重要问题的决议》以来,我国的社会主义精神文明建设取得了重大进展,可以说物质文明建设和精神文明建设“一手硬、一手软”的局面正在逐步改变。但是,我们也必须看到现实中精神文明各个部分发展不平衡的情况,在社会生活的深处,在居民家庭生活中不文明的现象还比较严重。因此,在当前的社会主义精神文明建设过程中既要重视社会层面的精神文明建设,宣传党中央的大政方针,促进思想道德和科学教育的发展,又要重视家庭层面的精神文明建设,继承和发展民族家庭传统…     

Use of Poset Theory with Big Datasets: A New Proposal Applied to the Analysis of Life Satisfaction in Italy

The aim of this work is to propose a tool for measuring a complex concept, and to apply it to big sets of data measured on ordinal and/or dichotomous scales. An important field of application are subjective data, that are often based on opinions or personal evaluations. Many national and international surveys employ this kind of data, measured among thousand of individuals. Thanks to the use of the “average rank” as a synthetic measure of a complex concept, we believe that poset theory could be a very useful approach for dealing with ordinal data avoiding the use of scaling procedures. Because classic poset approaches are at their best when applied to few data at a time, our idea is based on a procedure for sampling units from a big population using a simple criterion to summarize the resulting values appropriately. Applying the central limit theorem enables a comparison of the results obtained from different groups using statistical tests on the means. We used our Height of Groups by Sampling (HOGS) method to compare the average rank among groups that are defined by one or more socio-demographic variables influencing the level of the complex concept we wish to measure. The application of the HOGS procedure to life satisfaction in Italy generated convincing results, revealing significant differences between regions, genders and levels of formal education. We compared the results given by HOGS with the non linear principal component analysis and obtain an easy readable output with convincing precision and accuracy; we are confident that the HOGS procedure can be applied to many other concepts investigated in the social sciences.     

感知风险对在线旅游产品购买意愿的影响分析

旅游电子商务发展迅猛,互联网购物平台的虚拟性和远程性强化了消费者感知风险,它也成为影响旅游电子商务发展的重要因素之一.文章聚焦消费者感知风险,运用SPSS 19.0及AMOS 21.0软件,构建以5个维度的感知风险为自变量、购买意愿为因变量、信任为调节变量的结构方程模型,探讨变量间相关关系.结果发现:感知风险对信任的影响差异较大,仅经济风险感知与信任呈显著负相关;感知风险对购买意愿总效应皆呈负相关;信任作为中介变量存在明显的调节作用,有效地降低了感知风险对购买意愿的负向影响.
