<Emphasis Type="Italic">Knot yet</Emphasis>: minimum marriage age law,marriage delay,and earnings

Despite the historical highs for age at first marriage, little is known about the causal relationship between marriage delay and wages, and more importantly, the mechanisms driving such relationship. We attempt to fill the void. Building on an identification strategy proposed in Dahl (Demography 47:689–718, 2010), we first establish the causal wage effects of marriage delay. We then propose ways to distinguish among competing theories and hypotheses, as well as the channels through which marriage delay affects wages. Specifically, we take advantage of their different implications for causal relationship, across gender and sub-populations. We reach two conclusions. First, we find a positive causal impact of marriage delay on wages, with a larger effect for women. Comparison of IV and OLS estimates suggests that the observed relationship between marriage delay and wages is attributed to both selection in late marriages and true causal effects. Second, we find strong evidence that the positive, causal effects are almost exclusively through increased education for both men and women.     

Participatory ergonomics among female cashiers from a department store

The objective of this paper was to control ergonomic risks among female cashiers working in a department store belonging to the retail market. This study was conducted between May and November 2010. Participatory ergonomics was applied through knowing and understanding how the company works, establishing the work team (Ergo group), training the team in ergonomics-related topics, and making decisions and interventions. The sample was composed of 71 participants--mostly female cashiers--, and all of them have a musculoskeletal compromise, declaring pain or discomfort mainly in the neck, lower back, right wrist and shoulders. Among others, following problems were found: postural overload, repetitive work, manual load handling, mental fatigue, environmental discomfort, variable work schedules, extended working days, and absence of breaks. In the intervention, the main implemented changes were the redesign of workstation, complete change of chairs and keyboards, and the implementation of a rotation system, as well breaks for compensatory exercises. After that, an evident improvement of found problems was observed, therefore it can be concluded that participatory ergonomics is an attractive methodology, appropriate and efficient for solving and controlling ergonomic risks and problems.     

Causal Ordering of Basic Psychological Needs and Well-Being

What is the relationship between well-being and satisfaction of basic psychological needs overtime? The basic psychological needs theory is a subtheory of the self-determination theory that elaborates the concept of psychological needs and its relations to psychological health and well-being. The goals of this research was to establish the causal ordering between basic psychological needs and three psychological well-being indicators (subjective well-being, self-esteem and satisfaction with life), in a longitudinal study. We used a cross-lagged two-wave design. A total of 272 university students completed the questionnaire at the beginning and at the end of the semester. Relatedness at time 1 (T₁) had a positive and significant effect on all well-being indicators at time 2 (T₂); competence (T₁) had a positive and significant effect on all indicators except for self-esteem (T₂); finally, autonomy (T₁) did not have a significant effect on any of the well-being indicators (T₂). In conclusion, we confirm the causal ordering of competence and relatedness on well-being, according to the basic psychological needs subtheory. Universities, in general, and teachers, in particular, should promote relations between students and support the need of competence.     

Self-employment and earnings among immigrants in Australia

This article contributes to the small Australian literature on the earnings of immigrants in the self-employment sector. Earnings functions for both the foreign-born and Australian-born are estimated, and the results show that compared with native-born workers, foreign-born workers have higher earnings in the wage/salary sector but lower earnings in the self-employment sector.
Among the foreign-born, the results suggest that self-employed immigrants are less skilled compared with those who are wage/salary employed. Thus, low-skilled immigrants may be forced into self-employment.
There is no evidence of immigrant "catch-up" in the self-employment sector. Among wage/salary workers, however, immigrant wages are characterized by a "catch-up" effect.     

Age,religious beliefs,and sexual attitudes

Age effects on sexual attitudes were examined using the Hendrick and Hendrick (1987a) Sexual Attitude Scale. The study was cross-sectional, including people from various age groups, from young adults to older adults. The religious beliefs variable, which covaries substantially both with age and sexual attitudes, was controlled. Three main questions guided the study: (a) Is the four-factor structure (Permissiveness, Instrumentality, Communion, and Sexual Practices) previously identified in a sample of young students able to accurately account for data gathered over a full range of adult ages, (b) are older adults much less permissive and less instrumentalist than young people, and (c) to what extent are believers less permissive and instrumentalist than young people when age is taken into account? Factor analyses showed that at least five correlated factors were needed to account for the data; the fourth factor, Sexual Practices, divided itself into two distinct factors: Pleasure and Responsibility. Older adults and believers were shown to be less permissive than young people and nonbelievers, and this result held regardless of the participants educational level. As regards to instrumentality, however, the pattern of differences was extremely complex.     

论闻一多文艺思想的嬗变

闻一多在其早期受西方济慈等人的影响 ,认为“以美为艺术之核心” ,主张“纯艺术的艺术”并“纳诗于艺术之轨” ,坚持“做”诗并倡导诗歌的“三美”。然而随着那“不是混着好玩”岁月的流逝并亲身体验“生活的严重”后 ,他转而重视诗的社会价值并彻底摒弃了“唯美主义”的价值取向而站在人民的立场上呼唤“时代的鼓手”。文艺观由“艺术为艺术”变为“艺术为人生” ,从誓做“艺术的忠臣”到成为“人民的忠臣” ,我们在其文艺思想的嬗变过程中 ,看到了社会存在对社会意识的决定作用。     

Social dynamics of the multicultural classroom

Instruction and learning are socially determined activities, where social forces such as classroom atmosphere, social feelings, cultural sentiments, prejudice and stereotyping, interpersonal relations and expectations, as well as the reflection of social reality in subject matter all have a significant influence on the effectiveness of teaching and learning. The effective "multicultural" teacher has to be concerned about each individual student, and also be sensitive to the group and cultural affiliations of each of his or her students. Intercultural relations in the classroom may be a source of knowledge and mutual enrichment between culturally diverse learners if managed proactively by teachers. Frustration, misapprehensions and intercultural conflict are a more likely outcome if teachers do not deal with diversity in a sensitive manner.     

满铁“附属地”“除队兵”移民述论

20世纪初 ,日、俄为争夺中国东北展开了一场激烈的战争。最终 ,俄国以中国的利益为代价 ,暂时满足了日本的扩张野心 ,将俄国在中国东北南部的一切权益 ,未经中国政府同意 ,私下转让给日本。战后 ,日本在中国东北成立了“南满洲铁道株式会社”(简称满铁 )。满铁在对中国进行政治、经济侵略的同时 ,并在其“附属地”内推行“除队兵”移民侵略计划 ,以期达到壮大日本在中国东北的实力 ,抵御俄国的战略目的。但事与愿违 ,由于满铁决策者们的盲目求成 ,移民者的经营不善和厌恶农耕 ,使得满铁“附属地”的“除队兵”移民仅仅推行了 4年时间就以失败而告终     

Is the Way Young People Drive a Reflection of the Way Their Parents Drive? An Econometric Study of the Relation Between Parental Risk and Their Children's Risk

This article aims to investigate parental influence on high-risk behavior by young people. Although research on the topic of perception of risk demonstrates that it is socially constructed, the role of the family in this construction has rarely been studied. Using a French national survey of more than 1,200 young drivers between the ages of 18 and 25, and their parents, we attempt to understand the transmission of risk within families. Our econometric study shows that parents influence both the practices and representations of their children. When parental norms and values are transmitted, they are by no means accepted in a wholly passive way. Indeed, the parental model is in competition with other models that originate from both inside the family (brothers and sisters) and outside it (instructors). Furthermore, parental influence decreases over time as young people become more experienced drivers and construct their own identity with regard to risk.
