This study investigates English-speaking media’s legitimation of smartphone uses by Syrian refugees to explore how “otherness” is negotiated through technologies. Qualitatively examining the media coverage of the Syrian refugees’ use of smartphones between early 2015 and early 2017, we identified rhetorical devices and narrative strategies. The findings indicated a gradual shift in mediated legitimation strategies. In this process, two major themes emerged: (1) strategies to legitimate uses of technology and (2) demystifying refugees. The first theme identified that media articles focused on refugees’ instrumental uses of smartphones over the emotional uses as a legitimation strategy, utilizing metaphors and referencing third parties. The second theme showed media coverage further debunked conflation over poverty and precarity while negotiating otherness. Over time, the media coverage started to fall into the “humanitarian imaginary” of refugees by keeping them at the margins as people who need aid, largely limiting their legitimated mobile phone use to pragmatic uses. The findings contribute to understanding how media coverage can shape the way people make sense of the refugee population at a moment in time of technological appropriation amid ongoing political crises.  相似文献

Guided by Deci and Ryan’s (2000) self-determination theory, this survey study aimed to examine the effects of the talent development environmental factors on athlete burnout. Talented adolescent athletes (n = 691) filled out a survey form measuring the talent development environmental factors, needs satisfaction and burnout. The findings showed that three talent environmental factors (i.e., long-term development focus, holistic quality preparation and communication) were negative predictors of burnout via needs satisfaction. It was concluded that the three talent development environmental factors may be important for facilitating athletes’ needs satisfaction and preventing burnout.  相似文献

Given the significance of monitoring the critical environmental factors that facilitate athlete performance, this two-phase research aimed to validate and refine the revised talent development environment questionnaire (TDEQ). The TDEQ is a multidimensional self-report scale that assesses talented athletes’ environmental experiences. Study 1 (the first phase) involved the examination of the revised TDEQ through an exploratory factor analysis (n = 363). This exploratory investigation identified a 28-item five-factor structure (i.e., TDEQ-5) with adequate internal consistency. Study 2 (the second phase) examined the factorial structure of the TDEQ-5, including convergent validity, discriminant validity, and group invariance (i.e., gender and sports type). The second phase was carried out with 496 talented athletes through the application of confirmatory factor analyses and multigroup invariance tests. The results supported the convergent validity, discriminant validity, and group invariance of the TDEQ-5. In conclusion, the TDEQ-5 with 25 items appears to be a reliable and valid scale for use in talent development environments.  相似文献

Measuring the similarity between the semantic relations that exist between words is an important step in numerous tasks in natural language processing such as answering word analogy questions, classifying compound nouns, and word sense disambiguation. Given two word pairs (AB) and (CD), we propose a method to measure the relational similarity between the semantic relations that exist between the two words in each word pair. Typically, a high degree of relational similarity can be observed between proportional analogies (i.e. analogies that exist among the four words, A is to B such as C is to D). We describe eight different types of relational symmetries that are frequently observed in proportional analogies and use those symmetries to robustly and accurately estimate the relational similarity between two given word pairs. We use automatically extracted lexical-syntactic patterns to represent the semantic relations that exist between two words and then match those patterns in Web search engine snippets to find candidate words that form proportional analogies with the original word pair. We define eight types of relational symmetries for proportional analogies and use those as features in a supervised learning approach. We evaluate the proposed method using the Scholastic Aptitude Test (SAT) word analogy benchmark dataset. Our experimental results show that the proposed method can accurately measure relational similarity between word pairs by exploiting the symmetries that exist in proportional analogies. The proposed method achieves an SAT score of 49.2% on the benchmark dataset, which is comparable to the best results reported on this dataset.  相似文献

The use of computers and technology in mathematics education affects students’ learning, achievements, and affective dimensions. This study explores prospective Turkish primary mathematics teachers’ views about the use of computers in mathematics education. The sample comprised of 129 fourth-year prospective primary mathematics teachers from two different universities in Turkey. Data consisting of participants’ written responses were qualitatively analyzed and categorized according to TPACK. Results show that the prospective teachers’ views about computers and their use in mathematics are usually positive. They enjoy working with computers, even though they are only able to perform relatively minor calculations with computers. They stated that improved use of computers can help them to learn and teach mathematics more effectively. However, they did not feel confident about their ability to teach mathematics using computers.  相似文献

In this paper, we introduce a novel model of a hydro-turbine system with the effect of surge tank based on state-space equations to study the nonlinear dynamical behaviors of the hydro-turbine system. The critical points of Hopf bifurcation and the relationship of the stability satisfying with the adjustment coefficients are obtained from direct algebraic criterion. Furthermore, the bifurcation diagrams and Lyapunov exponents are presented and analyzed. The dynamical behaviors of the points with representative characteristics are identified and studied in detail. Both theoretical analysis and numerical simulations show that chaotic oscillations, which cannot stabilize the system, may occur with the changes of adjustment coefficients. To control the undesirable chaotic behaviors in this system, fuzzy sliding mode governor based on the sliding mode control (SMC) and the fuzzy logic are designed, and considering the bounded disturbance. Finally, series of numerical simulations are presented to verify the effectiveness of the proposed governor, which prove that the hydro-turbine governing system can maintain a better operation station under the designed governor.  相似文献

Athletes strive to reach expert performance in sport. However, evidence has shown that the talent development environmental factors significantly influence elite performance. This review study aimed to identify and classify the environmental factors that are essential for effective talent development in sport. A number of talent development environmental factors (e.g., media coverage, sport participation rate, birthplace, long-term development, and quality preparation) emerged from the literature. They were then grouped into three categories: milieu, individuals, and provisions. Implications for the practical practice and future research regarding effective talent development were provided.  相似文献

Starting off with a brief evocation of the origins of modern higher education in Turkey and the founding of Hacettepe University, the author proceeds to describe how the Department of English at this university spawned several other language‐related departments and eventually became itself the Department of Western Languages and Literatures. It is now subdivided into 5 units and subunits. Although the department itself is no longer a basic unit, it serves as testimony to the strength and the vitality of basic units.  相似文献
