基于logistic模型的外来人口婚姻迁移的影响因素分析——以珠三角某地区为例

婚姻迁移是人口迁移的一个方面,且增多趋势愈见明显。动机研究是人口迁移相对集中的关注问题。但是关于以迁入地为基点对婚姻迁移的影响因素分析相对较少。本文试图以某地区为例,研究其外来人口中婚姻迁移行为发生的影响因素,主要包括个人、户籍、经济、就业和城市适应五大因素,并引入logistic模型对测量变量进行统计分析。结果表明,个人因素对婚姻迁移的贡献最大,除了就业因素外,其他因素的贡献相似。尤其指出的是随着外来人口的城市适应程度提高,婚姻迁移的可能性将会增加。由此说明,外来人口城市生活的再社会化程度将为他们的社会融合奠定基础。     

Looking back: the experience of first sexual intercourse and current sexual adjustment in young heterosexual adults

A young person's first consensual sexual intercourse experience is often a remarkable and memorable experience. However, little systematic information exists regarding contextual factors of first intercourse, the affective salience of the experience, possible effects on sexual attitudes and beliefs, and subsequent sexual development and adjustment. This retrospective study aimed to examine these in a sample of 475 young adults. Overall, young men and women experienced intercourse for the first time around age 17, were in a committed relationship, and reported positive affective responses. Affective reactions to the first sexual intercourse experience, sexual self-efficacy, sexual aversion, and age at first intercourse affected individuals' current sexual adjustment; however, only sexual self-efficacy mediated between first intercourse and current sexual adjustment in young men and women. Older age at first intercourse was associated with less sexual self-efficacy and lower current sexual adjustment for women. This study provides initial data to suggest that the first sexual intercourse experience significantly impacts current sexual adjustment by affecting beliefs about sexual self-efficacy.     

Collaborative evaluation of a high school prevention curriculum: How methods of collaborative evaluation enhanced a randomized control trial to inform program improvement

Blending high-quality and rigorous research with pure evaluation practice can often be best accomplished through thoughtful collaboration. The evaluation of a high school drug prevention program (All Stars Senior) is an example of how perceived competing purposes and methodologies can coexist to investigate formative and summative outcome variables that can be used for program improvement. Throughout this project there were many examples of client learning from evaluator and evaluator learning from client. This article presents convincing evidence that collaborative evaluation can improve the design, implementation, and findings of the randomized control trial. Throughout this paper, we discuss many examples of good science, good evaluation, and other practical benefits of practicing collaborative evaluation. Ultimately, the authors created the term pre-formative evaluation to describe the period prior to data collection and before program implementation, when collaborative evaluation can inform program improvement.     

“营改增”政策试点的市场初步评估

会计市场咨询表明,＂营改增＂政策是一个相当积极的信号,对于上海行业细分和服务外包的发展、尤其是总部经济的发展有重大的推动作用。但从政策实施的实际效果看：首先受益的是制造业服务业分离企业,部分服务企业实际税负尚未降低;部分中资企业对于政策的了解较为局限,不懂得如何从＂营改增＂中获益;没有完整会计账册的小微企业无法享受增值税抵扣带来的税负减轻,反而由此在同业竞争中与大中企业相比丧失了部分议价竞争能力。针对上述问题,应采取相应的对策措施逐步加以解决。     

Assessments of patients with a 5-category or a 3-category practical classification system: validaty and practicality

In order to implement preventive programs to prevent back pain in nurses, assessments of the degree of passivity and mobility of patients is imperative. After all, the load in health care ergonomics, is often the patient. The degree of cooperation or resistance determines the load on the back for the nurses and the necessity of the use of lifting devices like patient lifters or sliding sheets. These assessments must be done in both a practical and a reliable way. For this purpose a 3-category and a 5- category system to assess the degree of patient mobility and passivity was developed and tested. The results are presented on the poster.     

Flying through the hospital: efficiency and safety of an ergonomic solution

In hospitals many horizontal transfers (from stretcher to bed etc.) are performed from the moment a patient is admitted (f.e. with an ambulance) through examination departments all the way to the wards. These transfers can be very strenuous and solutions may be to use a special lifting device that accompanies the patient on this route: a stretcher sling This is a specially designed disposable lifting sling for horizontal transfers and repositioning, the sling can easily be connected to a ceiling or mobile lift. The ambulance service, two hospitals and a manufacturer decided to study the effects. The stretcher sling travels with the patient. Does this provide an ergonomically sound solution and is this an effective and efficient solution? The results were positive, but a behavioral change was also necessary.     

A study of material composition disclosure practices in green footwear products

This work is based on the study of pioneering sustainable product development initiatives, and the analysis was guided by the cradle-to-cradle concept, which sees the waste of a given process as raw material for another, just like it happens in nature. Several studies on human factors have focused on factory conditions and workers dealing with product assembly. This research, however, relates more to consumer behavior, product use and end-of-life. The purchase of more environmentally- friendly products, in particular, is heavily influenced by the information made available by the companies. In this scenario, this article discusses three early but notable efforts on green product development, focusing on the disclosure practices adopted by the companies regarding the composition of their products. Research and data collection has focused on the footwear industry, whose products satisfy a basic human need and are ubiquitous worldwide. The use of hazardous materials and chemicals in shoe manufacturing, particularly the use of chromium - a highly toxic element - in addition to toxic solvents and adhesives and non-recyclable synthetic materials can pose serious risks to human health and the environment, even though the consumer usually is not aware of all the relevant characteristics of this kind of product.     

Ergonomics analysis of the productive environment of fashion clothing firm in Belo Horizonte-MG

A company making women's clothing, located in Belo Horizonte, Minas Gerais was studied in its ergonomic aspects with regard to the layout. With this study it was possible to establish the best positioning of machines and jobs of employees. The analysis criteria used were: frequency of use, functional grouping, sequence of use, flow and intensity of preferred connections. An ideal arrangement in the workplace provides improved manufacturing quality and employee performance and consequently higher production yields.     

Noise analysis in professional office chairs

The noise caused by the movement of users on their chairs in the work environment may indicate structural weaknesses and risk, and still significantly reduce productivity by increasing employees stress level. By understanding the activities to be developed in a work place one may understand what should be necessary to a good development, thereafter a search for improvement of labor activity with the aim of better use of resources in the operation of product use may be done. The analysis of the incremental variation of noise in professional chairs aims to identify its origin and the time the emission of noise starts during the period of use, its development and the major causative agents. Determining the characteristics of the sound of different materials and adjustments mechanisms of the chair can determine how different materials interact with each other. The measurement of these noises in an acoustic isolated room using directional microphones, if recorded and analyzed properly makes it possible to investigate and orientate to suspect elements in order to propose solutions and identify the quality of other similar chairs. Based on the results recommendations can be established for the orientation of users, managers and people responsible for the acquisition of the products, inducing them to review the employment of materials and the choice of the processes of production. These aspects are not covered in the Brazilian ergonomics norms and standards in the use of chairs.     

国际货币政策协调收益的研究现状及述评

开放经济下,国家之间的相互依存性越来越强.每个国家运用货币政策实现各自的宏观经济目标的同时,必然会对别国产生溢出效应.因此,国际货币政策协调历来就是国际货币经济学研究的一个核心问题.本文回顾和梳理了目前理论界关于国际货币政策协调的收益研究的理论框架、协调收益产生的来源、增加协调收益的机制设计研究等方面的研究成果,并加以评述,认为应该根据中国的基本国情建立一个能够能用于分析和指导中国参与国际货币政策协调的模型,以提高中国参与国际货币政策协调的收益.
