A new approach in vocational rehabilitation in Iceland: preliminary report

The lack of vocational rehabilitation in Iceland inspired the Janus Rehabilitation initiative in the year 2000. The team currently consists of two occupational therapists, a social worker, a physiotherapist, a psychologist, and a physician. Janus uses resources from local education establishments and is located at the Reykjavík Technical School. A client-centred approach is used, enabling a flexible rehabilitation timeframe. The aim is to help the client back to employment/education. Advantage is taken of the facilities of the school where integration between education and rehabilitation takes place. Forty individuals have been admitted, with a mean time from work of 2.9 years, (range: 0-11 years). Seventeen (43%) have returned to employment/education. Twenty-three of those entering the programme are still on invalidity pension. The Canadian Occupational Performance Measurement (COPM) shows improvement in occupational performance and satisfaction. The Icelandic Quality of Life measurement also shows improvement. The results have been promising. However, a larger group is needed in order to draw clear unequivocal conclusions.     

The relationship between fishermen's health and sleeping habits

This article describes research on fishermen's health and sleeping habits in Iceland. It presents the first findings of the project that were presented in October 2002 at a conference that was organized during Seamen Safety Week in Iceland. It covers physical and mental stress symptoms, sleep disturbance, and obesity, as well as fishermen's own reaction to their health and well-being. Take notice that the findings that are presented in this article can be found in a report presented in August, when the whole study will be finished. Finally, it is concluded how successful the response has been and how the project can be used positively with other studies. It is also noted that, in fact, these findings will be used for further studies linked to safety on board.     

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     

Managing skunkworks to achieve ambidexterity: The Robinson Crusoe effect

Literature on ambidexterity emphasizes the need for both exploration and exploitation. Large firms usually choose to implement structural ambidexterity to separate both activities. We here focus on an extreme case of such structural partitioning implemented as a secret skunkworks project in a large French automotive company. A qualitative survey using both primary and secondary data shows that the major basic and initial characteristics of a skunkworks (i.e. secrecy, urgency, and autonomy) created favorable conditions for the technological exploration. However, exploitation failed due to precisely those same characteristics coupled with the fact that the project did not respond to a specific market demand: The skunkworks suffered from what we call the "Robinson Crusoe effect." We therefore contribute to the literature on skunkworks, which have remained understudied in the academic literature, as well as on ambidexterity, by showing how the interrelation between different factors is crucial for structural ambidexterity to be successful     

Exploring the characteristics of rotating electric machines with factor analysis

Applications of multivariate statistics in engineering are hard to find, apart from those in quality control. However, we think that further insight into some technological cases may be gained by using adequate multivariate analysis tools. In this paper, we propose a review of the key parameters of rotating electric machines with factor analysis. This statistical technique allows not only the reduction of the dimension of the case we are analysing, but also reveals subtle relationships between the variables under study. We show an application of this methodology by studying the interrelations between the key variables in an electric machine, in this case the squirrel-cage induction motor. Through a step-by-step presentation of the case study, we deal with some of the topics an applied researcher may face, such as the rotation of the original factors, the extraction of higher-order factors and the development of the exploratory model. As a result, we present a worthwhile framework to both confirm our previous knowledge and capture unexplored facts. Moreover, it may provide a new approach to describing and understanding the design, performance and operating characteristics of these machines.     

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.     

A comparison of classification models to identify the Fragile X Syndrome

The main models of machine learning are briefly reviewed and considered for building a classifier to identify the Fragile X Syndrome (FXS). We have analyzed 172 patients potentially affected by FXS in Andalusia (Spain) and, by means of a DNA test, each member of the data set is known to belong to one of two classes: affected, not affected. The whole predictor set, formed by 40 variables, and a reduced set with only nine predictors significantly associated with the response are considered. Four alternative base classification models have been investigated: logistic regression, classification trees, multilayer perceptron and support vector machines. For both predictor sets, the best accuracy, considering both the mean and the standard deviation of the test error rate, is achieved by the support vector machines, confirming the increasing importance of this learning algorithm. Three ensemble methods - bagging, random forests and boosting - were also considered, amongst which the bagged versions of support vector machines stand out, especially when they are constructed with the reduced set of predictor variables. The analysis of the sensitivity, the specificity and the area under the ROC curve agrees with the main conclusions extracted from the accuracy results. All of these models can be fitted by free R programs.
