Growth in biomedical publications and scientific institutions in the Emirates (1998–2004): an Arabian renaissance?     

Neves K  Lammers WJ 《Health information and libraries journal》2007,24(1):41-49

OBJECTIVES: The United Arab Emirates is witnessing a rapid development in population and infrastructure, leading to an expansion in the educational field and the health care system, including universities, hospitals and research institutes. One potential outcome of this development is an increase in biomedical research publications. This was examined in this study. METHOD: Searches were made of three databases; PubMed, Current Contents and embase. All records from these databases related to the Emirates were downloaded and cross-referenced. Duplications were removed as well as erroneous records. A total of 1369 publications during 1998-2004 were obtained. RESULTS: Analysis of these records revealed that the Faculty of Medicine and Health Sciences, located at the federal University, was responsible for 48% of all biomedical publications. All hospitals together accounted for 24%, while other universities and other research institutes accounted for 13 and 14% respectively. Further analysis revealed that there had been no further growth in the number of publications since 1998. This is in contrast to the increasing number of institutions that have been set up in the 1998-2004 period; from 29 to 112. CONCLUSION: The Emirates are witnessing a rapid development in universities, colleges, hospitals and research centres. The ratio of publications, as yet, has not kept up with this development. The enormous growth in institutes, however, may, in time, herald an Arabian renaissance in scientific activity and related publications.  相似文献   

Modeling Growth in Electronic Learning Environments Using a Longitudinal Random Item Response Model     

Damazo T. Kadengye  Eva Ceulemans  Wim Van Den Noortgate 《Journal of Experimental Education》2015,83(2):175-202

In educational environments, monitoring persons' progress over time may help teachers to evaluate the effectiveness of their teaching procedures. Electronic learning environments are increasingly being used as part of formal education and resulting datasets can be used to understand and to improve the environment. This study presents longitudinal models based on the item response theory (IRT) for measuring persons' ability within and between study sessions in data from web-based learning environments. Two empirical examples are used to illustrate the presented models. Results show that by incorporating time spent within- and between-study sessions into an IRT model; one is able to track changes in ability of a population of persons or for groups of persons at any time of the learning process.  相似文献   

Estimation of a Nonlinear Intervention Phase Trajectory for Multiple-Baseline Design Data     

Ian Hembry  Rommel Bunuan  John M. Ferron  Wim Van den Noortgate 《Journal of Experimental Education》2015,83(4):514-546

A multilevel logistic model for estimating a nonlinear trajectory in a multiple-baseline design is introduced. The model is applied to data from a real multiple-baseline design study to demonstrate interpretation of relevant parameters. A simple change-in-levels (ΔLevels) model and a model involving a quadratic function (Quadratic) for the nonlinear intervention phase data were also estimated. In addition, a simulation study was conducted to assess Markov chain Monte Carlo estimation of the logistic model and compare its trajectory recovery with use of the ΔLevels and Quadratic models. While most of the logistic model's parameter values were recovered well, trajectory recovery was very reasonable using the simpler Quadratic model. Results are discussed along with recommendations for practitioners and directions for future research.  相似文献   

Design and implementation of multi-campus,modular master classes in biochemical engineering     

Niek Wuyts  Dorine Bruneel  Myriam Meyers  Etienne Van Hoof  Leander De Vos  Greet Langie 《European Journal of Engineering Education》2015,40(4):400-409

The Master of Science in engineering technology: biochemical engineering is organised in KU Leuven at four geographically dispersed campuses. To sustain the Master's programmes at all campuses, it is clear that a unique education profile at each campus is crucial. In addition, a rationalisation is required by increased cooperation, increased exchange of lecturers, and increased student mobility. To achieve this, a multicampus education system for the M.Sc. in engineering technology: biochemical engineering was developed by offering modules that are also available for students of other campuses. Such a module is primarily based on the research expertise present at the campus. In the development, special attention has been given to the optimal organisation of the modules, evaluation, required modifications of the current curricula, and the practical consequences for students following the module at another campus. Even in the first year of implementation, around 30% of the students followed a multicampus module, which indicates the potential success of the multicampus concept described here.  相似文献

The future is present in the past: A meta-analysis on the longitudinal associations of parent–adolescent relationships with peer and romantic relationships     

Susanne Schulz  Stefanie Nelemans  Hana Hadiwijaya  Theo Klimstra  Elisabetta Crocetti  Susan Branje  Wim Meeus 《Child development》2023,94(1):7-27

Positive peer and romantic relationships are crucial for adolescents' positive adjustment and relationships with parents lay the foundation for these relationships. This longitudinal meta-analysis examined how parent–adolescent relationships continue into later peer and romantic relationships. Included longitudinal studies (k = 54 involving peer relationships, k = 38 involving romantic relationships) contained demographically diverse samples from predominantly Western cultural contexts. Multilevel meta-regressions indicated that supportive and negative parent–adolescent relationships were associated with supportive and negative future peer and romantic relationships. Meta-analytic structural equation modeling (k = 54) indicated that supportive parent–adolescent relationships unidirectionally predicted supportive and negative peer relationships, while negative parent–adolescent relationships were bidirectionally associated with supportive and negative peer relationships. Maintaining mutually supportive relationships with parents may help adolescents to develop positive social relationships.  相似文献

Creating value in ecosystems: Crossing the chasm between knowledge and business ecosystems   总被引：1，自引：0，他引：1  

Bart Clarysse  Mike Wright  Johan Bruneel  Aarti Mahajan 《Research Policy》2014

Policy makers take initiatives to stimulate knowledge ecosystems in technology hotspots. It is implicitly assumed that these ecosystems will lead to value networks through which the participating companies can realize a competitive advantage. Value networks refer to business ecosystems where the value proposition is offered by a group of companies which are mutually complementary. The strategy literature suggests that business ecosystems lead to competitive advantages for each of the partners in the ecosystem. Based on a unique hand-collected database of 138 innovative start-ups in the region of Flanders, we analyze the knowledge and business ecosystem and the financial support network. We find that the knowledge ecosystem is well structured and concentrated around a number of central actors while the business ecosystem is almost non-existent at the local level. Further, we find that the financial support network is almost 100% publicly backed and fails to bridge the knowledge and business ecosystem. The implications for policy makers who tend to focus on the development of local ecosystems are discussed.  相似文献   

On Subject Variations in Achievement Motivations: A Study in Business Subjects     

Dirk T. Tempelaar  Sybrand Schim van der Loeff  Wim H. Gijselaers  Jan F. H. Nijhuis 《Research in higher education》2011,52(4):395-419

Student achievement motivations are crucial in learning in two ways: as a determinant and an aim of learning. In this study, we focus on two related questions with regard to achievement motivations: to what extent are they subject-specific, and to what extent are they malleable? Answers to both questions are especially important when aiming to influence motivations. Malleability of motivation is studied by designing structural equation models that explain achievement motivation out of the most stable student characteristics one can think of: gender, and personality traits. Subject matter variability is studied by estimating these models for five main subject areas in a business program. The motivation construct we use is based on the expectancy-value model and distinguishes four different facets: cognitive competence, difficulty, task-value and affect. We find evidence for strong subject-specificity and considerable non-malleability of achievement motivation; part of that last aspect is a remarkably constant over-confidence gender gap present in the data of the calibration of competency beliefs and performance in all subject areas.  相似文献   

Finite element modelling and experimental study of oblique soccer ball bounce     

Rezaei A  Verhelst R  Van Paepegem W  Degrieck J 《Journal of sports sciences》2011,29(11):1201-1213

In this study, we develop a finite element model to examine the oblique soccer ball bounce. A careful simulation of the interaction between the ball membrane and air pressure in the ball makes the model more realistic than analytical models, and helps us to conduct an accurate study on the effect of different parameters on a bouncing ball. This finite element model includes a surface-based fluid cavity to model the mechanical response between the ball carcass and the internal air of the ball. An experimental set-up was devised to study the bounce of the ball in game-relevant impact conditions. Ball speed, angle, and spin were measured before and after the bounce, as well as ball deformation and the forces during the impact. The finite element model has been validated with three different sets of data, and the results demonstrate that the finite element model reported here is a valuable tool for the study of ball bounce. After validation of the model, the effect of the friction coefficient on soccer ball bounce was studied numerically. Simulation results show that increasing the friction coefficient may result in reversal of the horizontal impact force.  相似文献
