The Relative Efficiency of Departments at a Turkish Engineering College: A Data Envelopment Analysis
In this study, Data Envelopment Analysis is used to measure relative efficiencies of academic departments of an engineering
college. Input and output criteria are determined and measured utilizing the academic personnel performance measurement scheme
of the College. New measures are developed to compare departments of different disciplines. The discriminating power of the
measurement models is improved by restricting criteria weights directly and by using a multiple criteria decision making approach.
Sensitivity of the results to exclusion of a criterion and changes in relative importance of the criteria is analyzed. Evaluation
of the results jointly by the college administration and the departments is explained for a successful efficiency improvement
mechanism. 相似文献

Environmental attitudes depend on the relative importance that individuals attach to themselves, other people, or all living things. These distinct bases have been found to predict environmental concern, and may act as statistically significant determinants of pro-environmental behaviours. We claim that examining the complex nature of value orientations and concern levels among elementary school students as well as the interrelationships between these attributes could guide researchers and educators in Turkey. This study aimed (1) to explore Turkish elementary students’ ecocentric and anthropocentric attitudes, and environmental apathy; (2) to investigate their egoistic, altruistic and biospheric value orientations as well as their environmental concerns; (3) to examine relationships among environment-related attributes and (4) to determine the role of gender on these attributes. Participants seemed to be highly concerned and held favourable ecocentric attitudes. Furthermore, students with higher levels of anthropocentric attitudes tended to exhibit higher levels of environmental apathy, and those expressing biospheric concerns held lower levels of egoistic concerns. The findings suggest that girls were significantly more concerned about environmental problems and tended to value nature more for its own sake than boys. 相似文献

The purpose of this study was to compare the effects of 1 and 2 days per week of strength training on upper body strength, lower body strength, and motor performance ability in children. Twenty-one girls and 34 boys between the ages of 7.1 and 12.3 years volunteered to participate in this study. Participants strength trained either once per week (n = 22) or twice per week (n = 20) for 8 weeks at a community-based youth fitness center. Each training session consisted of a single set of 10-15 repetitions on 12 exercises using child-size weight machines. Thirteen children who did not strength train served as age-matched controls. One repetition maximum (1RM) strength on the chest press and leg press, handgrip strength, long jump, vertical jump, and flexibility were assessed at baseline and posttraining. Only participants who strength trained twice per week made significantly greater gains in 1RM chest press strength, compared to the control group (11.5 and 4.4% respectively, p < .05). Participants who trained once and twice per week made gains in 1RM leg press strength (14.2 and 24.7%, respectively) that were significantly greater than control group gains (2.4%). On average, participants who strength trained once per week achieved 67% of the 1RM strength gains. No significant differences between groups were observed on other outcome measures. These findings support the concept that muscular strength can be improved during the childhood years and favor a training frequency of twice per week for children participating in an introductory strength training program. 相似文献

This Monte Carlo simulation study compares methods to estimate the effects of programs with multiple versions when assignment of individuals to program version is not random. These methods use generalized propensity scores, which are predicted probabilities of receiving a particular level of the treatment conditional on covariates, to remove selection bias. The results indicate that inverse probability of treatment weighting (IPTW) removes the most bias, followed by optimal full matching (OFM), and marginal mean weighting through stratification (MMWTS). The study also compared standard error estimation with Taylor series linearization, bootstrapping and the jackknife across propensity score methods. With IPTW, these standard error estimation methods performed adequately, but standard errors estimates were biased in most conditions with OFM and MMWTS. 相似文献

We are surrounded by an endless variation of objects. The ability to categorize these objects represents a core cognitive competence of humans and possibly all vertebrates. Research on category learning in nonhuman animals started with the seminal studies of Richard Herrnstein on the category “human” in pigeons. Since then, we have learned that pigeons are able to categorize a large number of stimulus sets, ranging from Cubist paintings to English orthography. Strangely, this prolific field has largely neglected to also study the avian neurobiology of categorization. Here, we present a hypothesis that combines experimental results and theories from categorization research in pigeons with neurobiological insights on visual processing and dopamine-mediated learning in primates. We conclude that in both fields, similar conclusions on the mechanisms of perceptual categorization have been drawn, despite very little cross-reference or communication between these two areas to date. We hypothesize that perceptual categorization is a two-component process in which stimulus features are first rapidly extracted in a feed-forward process, thereby enabling a fast subdivision along multiple category borders. In primates this seems to happen in the inferotemporal cortex, while pigeons may primarily use a cluster of associative visual forebrain areas. The second process rests on dopaminergic error-prediction learning that enables prefrontal areas to connect top down the relevant visual category dimension to the appropriate action dimension. 相似文献

We are experiencing a significant shift in management practices—moving from intuition, experience, and gut‐feeling driven decision‐making to one that is driven by data, evidence, and computational sciences. This shift, which is often called the analytics revolution, is not only changing the business landscape from a practical perspective but also redefining the white‐collar job market. The goal of this study is to employ a data‐ and analytics‐driven approach to analyze a large and feature‐rich dataset (which is composed of the recent job postings and the extant published literature) to characterize the state of the current business job market, especially to magnify the analytics related features and expectations including the geographic (i.e., local vs. global) differentiators. Using several graphical and tabular representations, in this paper we report on our thought‐provoking findings that collectively illustrate the changing face of knowledge, skills, and abilities required by the current local and global business job markets. 相似文献

Humanoid robots equipped with social skills have come to be used increasingly in the field of education across various subfields such as science education, special education, and foreign language education. In order to enhance the use of humanoid robots in educational settings, and to comprehensively evaluate its impact on the transformation of the class, understanding students’ attitudes towards the use of robots for educational purposes plays a critical role. This paper outlines the implementation and validation procedures of an educational robot attitude scale (ERAS) developed to measure the attitudes of secondary school students towards the use of humanoid robots in educational settings. The sample of the study comprised of 232 secondary school students. The development and validation process consisted of exploratory factor analysis and convergent validity. The developed scale consists of 17 items and represents four factors of students’ attitude: engagement, enjoyment, anxiety and intention. These four factors accounted for 66% of the total variance of the scale. Internal consistency coefficient for the whole scale was found .90 according to the reliability analysis. The results of the study suggest that the scale is a valid, reliable, and efficient tool for measuring the dimensions of students’ attitudes towards humanoid robots in educational settings. 相似文献
