Several studies have investigated the association between students' seating positions and their classroom performance. However, the role of personality traits on seating preference in the classroom has not been well investigated. The aim of the study was to understand how students choose their seats according to their personality traits in a classroom context and the influence of personality characteristics and seat selection on educational achievement. The seating positions of the medical students were recorded on an architectural plan during each class session, and the means and standard deviations of the students' locations were calculated in X and Y orientations. The locations of the students in the class were analyzed based on three architectural classifications: interactional zone, distance from the board, and access to the aisles. The NEO Five-Factor Inventory was used to evaluate the five main personality characteristics of the students. Midterm and final exam scores were used to measure the students' educational achievement. Analysis of variance showed a statistical significance correlation between the interactional zones and both agreeableness and conscientiousness. Mantel–Haenszel analysis showed a statistical significance association between sex and agreeableness and openness to experiences, which was mainly caused by zone II. Among the tested characteristics, a statistically significant relationship was observed between agreeableness and final exam scores. There was a statistical significance difference in openness and extraversion between the students with a high number of absences and their classmates. A relationship between the student's locations in the class, their educational achievements, and some of their personality characteristics are addressed.  相似文献   

Student perceptions of a culturally diverse classroom environment     

Sadaquat Ali  David Rohindra 《Research in Science & Technological Education》2013,31(2):149-164

The research in the paper involves an application of the actual and preferred versions of a previously‐validated learning environment instrument: the What is Happening in This Classroom (WIHIC) instrument in a complex multi‐cultural university‐level environment. Statistical analyses suggest the instrument is valid in this setting (with Cronbach alpha above 0.80 for all scales), and data analyses using ANOVA point to relatively few differences between preferred and actual environments. The research findings suggest all students would prefer a more interactive and equitable classroom, the latter issue of particular importance for one cohort, namely Indo‐Fijians (descendents of ethnic Indian indentured labourers). With the exception of this, there are few differences based on ethnicity and further analysis also suggests no differences in perceptions vis‐à‐vis collaborative versus competitive learning environments, excepting that analysis based on gender shows females have a slight preference for a more cooperative learning environment.  相似文献

DistanceRank: An intelligent ranking algorithm for web pages     

Ali Mohammad Zareh Bidoki  Nasser Yazdani 《Information processing & management》2008

A fast and efficient page ranking mechanism for web crawling and retrieval remains as a challenging issue. Recently, several link based ranking algorithms like PageRank, HITS and OPIC have been proposed. In this paper, we propose a novel recursive method based on reinforcement learning which considers distance between pages as punishment, called “DistanceRank” to compute ranks of web pages. The distance is defined as the number of “average clicks” between two pages. The objective is to minimize punishment or distance so that a page with less distance to have a higher rank. Experimental results indicate that DistanceRank outperforms other ranking algorithms in page ranking and crawling scheduling. Furthermore, the complexity of DistanceRank is low. We have used University of California at Berkeley’s web for our experiments.  相似文献   

Seminal plasma levels of free 8-isoprostane and its relationship with sperm quality parameters     

Ali Khosrowbeygi  Nosratollah Zarghami 《Indian journal of clinical biochemistry : IJCB》2008,23(1):49-52

There is growing evidence that damage to spermatozoa by reactive oxygen species play a key role in male infertility. The aim of this study was to assess seminal plasma free 8-Isoprostane levels in men with asthenozoospermia, asthenoteratozoospermia and oligoasthenoteratozoospermia compared to normozoospermic males and its correlation with seminal parameters. The case group consisted of men with asthenozoospermia (n=15), asthenoteratozoospermia (n=16) and oligoasthenoteratozoospermia (n=15). The control group consisted of 16 males with normozoospermia. After Purification of Free 8-Isoprostane by affinity column, its concentration was measured by enzyme immunoassay method. Free 8-Isoprostane evaluation showed significantly greater values in the total case group (n=46) versus control group (18.23±3.56 vs 2.6±0.38 ng/ml). In each case group free 8-Isoprostane also showed a significant increasing compared to normozoospermic males. Free 8-Isoprostane showed an inversely significant correlation with sperm motility and sperm morphology. Lipid peroxidation could have significant role in etiology of sperm abnormalities. Measurement of 8-Isoprostane can be used as a specific biomarker for assessing lipid peoxidation in sperm.  相似文献   

Vocational Schools in Turkey: An Administrative and Organizational Analysis     

Simsek  Hasan  Yildirim  Ali 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2000,46(3-4):327-342

The data used in this paper were derived from a larger project which had the aim of critically evaluating the Turkish vocational education system on a number of different levels. This article examines the administrative and organisational practices in a selected group of secondary vocational schools in Turkey from the point of view of school administrators, teachers and industrial managers. The results indicate that the Turkish vocational education system is characterised by a centralised, top-down bureaucracy, which inhibits innovative capacity. The authors argue that a degree of decentralisation is necessary at various levels of the system.  相似文献   

Temporal expert profiling: With an application to T-shaped expert finding     

Mahdi Dehghan  Maryam Biabani  Ahmad Ali Abin 《Information processing & management》2019,56(3):1067-1079

Cost optimization continues to be a critical concern for many human resources departments. The key is to balance between costs and business value. In particular, computer science organizations prefer to hire people who are expert in only one skill area and have a slight superficial knowledge in other areas that gives them the ability to collaborate across different aspects of project. Community Question Answering networks provide good platforms for people and organizations to share knowledge and find experts. An important issue in expert finding is that an expert has to constantly update his knowledge after being saturated in his field of expertise to still be identified as expert. A person who fails to preserve his expertise is likely to lose his expertise. This work justifies this question that does take the concept of time into account improve the quality of expertise retrieval. We propose a new method for T-shaped expert finding that is based on temporal expert profiling. The proposed method takes the temporal property of expertise into account to mine the shape of expertise for each candidate expert based on his profile. To this end, for each candidate expert, we take snapshots of his expertise trees at regular time intervals and learn the relation between temporal changes in different expertise trees and candidates’ profile. Finally, we use a filtering technique that is applied on top of the profiling method, to find shape of expertise for candidate experts. Experimental results on a large test collection show the superiority of the proposed method in terms of quality of results in comparison with state-of-the-art.  相似文献   

The reflection of offline activities on users’ online social behavior: An observational study     

Seyed Amin Mirlohi Falavarjani  Fattane Zarrinkalam  Jelena Jovanovic  Ebrahim Bagheri  Ali A. Ghorbani 《Information processing & management》2019,56(6):102070

The ever increasing presence of online social networks in users’ daily lives has led to the interplay between users’ online and offline activities. There have already been several works that have studied the impact of users’ online activities on their offline behavior, e.g., the impact of interaction with friends on an exercise social network on the number of daily steps. In this paper, we consider the inverse to what has already been studied and report on our extensive study that explores the potential causal effects of users’ offline activities on their online social behavior. The objective of our work is to understand whether the activities that users are involved with in their real daily life, which place them within or away from social situations, have any direct causal impact on their behavior in online social networks. Our work is motivated by the theory of normative social influence, which argues that individuals may show behaviors or express opinions that conform to those of the community for the sake of being accepted or from fear of rejection or isolation. We have collected data from two online social networks, namely Twitter and Foursquare, and systematically aligned user content on both social networks. On this basis, we have performed a natural experiment that took the form of an interrupted time series with a comparison group design to study whether users’ socially situated offline activities exhibited through their Foursquare check-ins impact their online behavior captured through the content they share on Twitter. Our main findings can be summarised as follows (1) a change in users’ offline behavior that affects the level of users’ exposure to social situations, e.g., starting to go to the gym or discontinuing frequenting bars, can have a causal impact on users’ online topical interests and sentiment; and (2) the causal relations between users’ socially situated offline activities and their online social behavior can be used to build effective predictive models of users’ online topical interests and sentiments.  相似文献
