Many studies have shown that young males of Turkish descent are disadvantaged in terms of educational opportunity in Germany. In this, the lower educational successes of children from migrant families are neither simple effects of lower levels of social capital nor of lower educational aspiration. With the aim of tracing unexplained mechanisms of the intergenerational transmission of educational chances, the interdependency of educational success or failure of young men of Turkish descent and adolescent processes of detachment and family relations were reconstructed using an intergenerational research design. This shows the major importance of parents?? processing of their immigration experiences in the context of discrimination and disadvantage, the effects of this on the parent-child-relationship, especially in adolescence, and the impact of intergenerational dynamics on the realization, processing and effects of differing educational aspirations and careers.  相似文献

Human cadaveric tissue is the fundamental substrate for basic anatomic and surgical skills training. A qualitative assessment of the use of human cadavers preserved by Thiel's method for a British Association of Urological Surgeons-approved, advanced laparoscopic renal resection skills training course is described in the present study. Four trainees and four experienced laparoscopic surgeons participated in the course. All participants completed a five-point Likert scale satisfaction questionnaire after their training sessions. The quality of cadaveric tissue and the training session were assessed with particular emphasis placed on the ease of patient positioning, the ease of trocar placement, the preservation of tissue planes, the ease of renal pedicle dissection, and the quality of tissue preservation. All of the participants highly rated the quality of the cadaveric tissue embalmed by Thiel's method (mean scores for quality on the five-point Likert scale were 4.5 and 4.3 by the trainees and experienced laparoscopic surgeons, respectively). All of the steps of laparoscopic renal resection were rated 4.0 or more on the Likert scale by both trainees and faculty members. The initial response rates for using a human cadaver embalmed by Thiel's method as a training tool for laparoscopic nephrectomy showed encouraging results. The performance of a laparoscopic nephrectomy on a human cadaver embalmed by Thiel's method bears close resemblance to real laparoscopic nephrectomy procedures, and thus demonstrates added advantages to the previously reported models.  相似文献

The client's perception of the therapy relationship is an essential component of modern theoretical orientations. To date, there is a lack of quantitative research examining how the therapeutic bond affects therapy outcomes in college counseling. This study used path analysis to examine longitudinal therapy outcomes with 423 college students. Having a stronger therapeutic bond predicted decreased symptoms of depression, social anxiety, and academic distress. Findings support continued attention to developing a working relationship.  相似文献

Lawson's test of formal reasoning was used in the Israeli educational context in order to investigate the relationship between students' achievement in science and in mathematics, to compare the performance of boys and girls, and to compare the performance of Israeli and U.S. populations. It was found that, in general, boys outperform girls; there is only a small correlation between achievement in science and math and Lawson test; and that the Israeli population achieved significantly higher than the U.S. population on the Piagetian skills measured by the test: It was concluded that the future use of Lawson's test by the high school teacher is doubtful.  相似文献

The paper focuses on educational projects developed in the ETSII (Escuela Técnica Superior de Ingenieros Industriales) of the Polytechnic University of Madrid during the past few years. These projects were developed as new tools for enhancing the active role of students, for improving practical teaching, especially by means of virtual laboratories and different sets of problems and exercises, and for promoting self-learning. The paper analyses the use of ICT in teaching, with the case of a developed e-learning platform as a tracking system for subjects. The paper concludes by discussing the new educational trends in the Centre, devoted to develop an active role of students by activities such as peer mentoring and laboratory monitors programs, and competitions for achieving multidisciplinary engineering challenges.  相似文献

Within the K-12 educational arena, interviews are a required component of the selection process and represent the most popular predictor for hiring teachers (Castetter & Young, 2000). Noticeably absent from empirical examination is the psychological interplay between interviewers and interviewees during the face-to-face teacher selection interview. While some research has identified potential ways in which isolated psychological variables affect hiring decisions, there has been little systematic investigation of how such variables, combined, influence the face-to-face teacher selection interview process. To begin filling a research void that exists in face-to-face teacher interviewing, this paper will: (a) review relevant literature on the selection interview and psychological variables' (e.g., similarity and attraction, likeability, perceived expertness) effects on the interview process, (b) apply findings of psychological research to the teacher selection interview (dyad vs. panel format), (c) propose a model that integrates these various influences, and (d) outline research directions that would allow for empirical validation of the proposed model.  相似文献

Recently, in the wake of the Bologna Declaration and similar international initiatives, there has been a rapid increase in the number of university courses and programmes taught through the medium of English. Surveys have consistently shown the Nordic countries to be at the forefront of this trend towards English-medium instruction (EMI). In this paper, we discuss the introduction of EMI in four Nordic countries (Denmark, Finland, Norway and Sweden). We present the educational setting and the EMI debate in each of these countries and summarize relevant research findings. We then make some tentative suggestions for the introduction of EMI in higher education in other countries. In particular, we are interested in university language policies and their relevance for the day-to-day work of faculty. We problematize one-size-fits-all university language policies, suggesting that in order for policies to be seen as relevant they need to be flexible enough to take into account disciplinary differences. In this respect, we make some specific suggestions about the content of university language policies and EMI course syllabuses. Here we recommend that university language policies should encourage the discussion of disciplinary literacy goals and require course syllabuses to detail disciplinary-specific language-learning outcomes.  相似文献

The study investigated the extent of adoption of electronic theses and dissertations in university libraries in Nigeria. Data collection for the study was via online questionnaire. The study revealed that digitization of theses and dissertations started between 1980 and 1995. It was found that only a few university libraries have embraced digitization of theses and dissertations in Nigeria. Benefits of electronic theses and dissertations were identified as improving university ranking and visibility, increasing access to the theses and dissertations, saving space in the library, enabling others link to the work with persistent URLs, preserving the work for future generations, and saving costs for students. Challenges such as unstable internet connectivity, lack of funding, irregular power supply, lack of information technology personnel, absence of electronic theses and dissertations submission policy, and copyright issues were identified. It is hoped that the study might provide insights useful for librarians planning to embark on the digitization of theses and dissertations project.  相似文献

The aim of this article is to introduce the R package semds for structural equation multidimensional scaling. This methodology combines multidimensional scaling with latent variable features from structural equation modeling and is applicable to asymmetric and three-way input dissimilarity data. This key idea of this approach is that the input data are assumed to be imperfect measurements of a latent symmetric dissimilarity matrix. The parameter estimation is performed via an alternating least squares multidimensional scaling procedure that minimizes the stress. The latent dissimilarities are estimated as factor scores within a structural equation modeling framework. Applications shown in the article involve data associated with the banking crisis and data from avalanche research. The models fitted with the semds package are compared to related methods from multidimensional scaling. The R code to reproduce all the computations is provided in the supplementary materials.  相似文献
