In this work, we present the first quality flaw prediction study for articles containing the two most frequent verifiability flaws in Spanish Wikipedia: articles which do not cite any references or sources at all (denominated Unreferenced) and articles that need additional citations for verification (so-called Refimprove). Based on the underlying characteristics of each flaw, different state-of-the-art approaches were evaluated. For articles not citing any references, a well-established rule-based approach was evaluated and interesting findings show that some of them suffer from Refimprove flaw instead. Likewise, for articles that need additional citations for verification, the well-known PU learning and one-class classification approaches were evaluated. Besides, new methods were compared and a new feature was also proposed to model this latter flaw. The results showed that new methods such as under-bagged decision trees with sum or majority voting rules, biased-SVM, and centroid-based balanced SVM, perform best in comparison with the ones previously published. 相似文献

The present experiment sought to further understanding of the effects of personalised audiovisual stimuli on psychological and psychophysiological responses during exercise in adults with obesity. Twenty-four participants (Mage = 28.3, SD = 5.5 years; MBMI = 32.2, SD = 2.4) engaged in self-paced exercises on a recumbent cycle ergometer and three conditions (sensory stimulation [ST], sensory deprivation [DE], and control [CO]) were administered. Perceptual (attentional focus and perceived exertion), affective (affective state and perceived activation), and psychophysiological (heart rate variability) parameters were monitored throughout the exercise bouts. A one-way repeated measures analysis of variance was used to compare self-reported and psychophysiological variables (main and interaction effects [5 Timepoints × 3 Conditions]). The results indicate that ST increased the use of dissociative thoughts throughout the exercise session (ηp2 = .19), ameliorated fatigue-related symptoms (ηp2 = .15) and elicited more positive affective responses (ηp2 = .12) than CO and DE. Accordingly, personally-compiled videos are highly effective in ameliorating exertional responses and enhancing affective valence during self-paced exercise in adults with obesity. Audiovisual stimuli could be used during the most critical periods of the exercise regimen (e.g., first training sessions) when individuals with obesity are more likely to focus on fatigue-related sensations. 相似文献

ABSTRACT
Background and Context
Sports and technology are often pitted as being at odds with one another. While there are several educational activities that make reference to sports we seldom see sports used as an authentic context for learning computing. 相似文献4.
This study examined the associations between classmates’ reading-related gender stereotypes and students’ reading self-efficacy, self-concept, motivation, and achievement. Our sample consisted of 1,508 fifth-grade students (49% girls; age: 10.89 years); data were collected at two time points. Multilevel analyses yielded two main results: First, there was a relation between students’ individual reading-related gender stereotypes and their reading self-concept, self-efficacy, and motivation with boys experiencing negative and girls experiencing positive effects. Second, a contextual effect was found: after controlling for students’ individual reading-related gender stereotypes, classmates’ gender stereotypes were negatively related to all of the boys’ reading outcomes. The results provide evidence for the assumption that classmates are important communicators of gender stereotypes and that they reinforce conforming behaviors. 相似文献

ABSTRACTPurpose: To analyze the Brazilian experience in designing and implementing a recent extension policy reform based on agroecology, and reflect on its wider theoretical implications for extension reform literature. Design/methodology/approach: Using a critical public analysis we characterize the evolution of Brazilian federal extension policy between 2004 and 2015, using political and legal documents as well as recent academic studies for policy frame characterization and implementation analysis. Findings: The case reveals the difficulty of implementing an agroecological extension approach as part of the endogenous development proposal expressed in 2004 PNATER. The agroecological proposal tended to be impaired by a more general demand for diverse public policy programs implementation, facing a series of institutional constraints. A policy reframing process led to a search for alternatives to make it compatible with a federal centralization trend and public administration rules, resulting in a contracting out emphasis. Theoretical implications: The study shows the political economy aspects of extension reform, and how original plans are influenced by path dependence and different and contrasting demands. Practical implications: The study points to the importance of considering political and institutional environments in extension reforms, and indicates a necessity for additional reflection about strategies for scaling up proposals for agroecological and sustainability oriented extension. Originality/value: Few studies are dedicated to understanding the political economy of extension reform, and reform of Brazilian rural extension systems. 相似文献

This paper identifies salient practices of faculty mentors of undergraduate research (UR) as indicated in the extensive literature of the past two decades on UR. The well-established benefits for students involved in UR are dependent, first and foremost, on high-quality mentoring. Mentorship is a defining feature of UR. As more and different types of colleges and universities strive to meet student demand for authentic scholarly experiences, it is imperative to identify what effective UR mentors do in order to ensure student engagement, quality enhancement, retention, and degree-completion. We offer an original analysis of the literature on UR mentoring in which we identify 10 significant “lessons learned,” or evidence-based practices of effective UR mentors that apply broadly across disciplines, students, institutions, and mentoring approaches. 相似文献

This study examines how the Early Years Educators at Play (EYEPlay) professional development (PD) programme supported inclusive learning settings for all children, including English language learners and students with disabilities. The EYEPlay PD model is a year‐long programme that integrates drama strategies into literacy practices within real‐classroom contexts. Inclusive education refers to ensuring equal opportunities to access and participation in learning activities for all students. Cultural‐historical activity theory was used to understand and unpack the drama practices. Twelve semi‐structured focus group interviews were conducted with 19 preschool teachers. The data were analysed via constant‐comparative and interpretive methods. The study findings showed that EYEPlay PD practices enhanced inclusive learning settings for diverse groups of students by increasing access and expanding opportunities to learn, and supporting a positive learning environment. 相似文献

This paper is aimed to investigate the operating characteristics of a static synchronous compensator (STATCOM) integrated with superconducting magnetic energy storage (SMES) for high power applications in the transmission network level. The STATCOM controller topology comprises multi-level multi-pulse neutral-point clamped-type (NPC) voltage source inverters (VSIs) using the harmonics cancellation technique, and incorporates a SMES coil. An innovative two-quadrant multi-level dc-dc converter is proposed to effectively interface the STATCOM with the superconducting coil using a buck-boost topology with neutral point voltage control capabilities; thus enabling to simultaneously control both active and reactive power exchange with the high voltage power system. A detailed analysis of major system variables is presented, including analytical results and digital simulations using the MATLAB/Simulink environment. Moreover, a three-level control scheme is designed, including a full decoupled current control strategy in the d-q reference frame with a novel controller to prevent the STATCOM dc bus capacitors voltage drift/imbalance and an enhanced power system frequency controller. 相似文献

Abstract The purpose of this investigation was to determine the extent to which computers assist high school students in learning English language vocabulary. The experience describes an experimental investigation conducted in a Teacher‐Training Practising Secondary School in Cameroon on the use of computer‐assisted software to teach English vocabulary. Specifically, the major thrust of this investigation was to compare the effects of using computers in the teaching of English language vocabulary with the conventional method of teaching. Students were split into two groups: an experimental group and a control group. The latter group received the conventional method while the former group was given the computer software application. Results indicated that there was very little significant difference in the academic performance of both groups. However, the experimental group demonstrated positive attitudes toward a computer and the software program. Abstract français: Le but de cette recherche était de déterminer jusqu'o[ugrave] les ordinateurs peuvent aider des étudiants d'école secondaire à apprendre le vocabulaire anglais. L'article décrit la recherche conduite dans un institut de formation des maîtres du second degré au Cameroun sur l'utilisation de logiciels pour l'enseignement du vocabulaire anglais. En fait, l'objectif majeur de cette recherche était de comparer les effets de l'emploi des ordinateurs à cette fin avec les méthodes traditionelles de formation. On a divisé les étudiants en deux groupes: expérimental et contrôle. Ce dernier a reçu cette formation traditionelle, tandis que le premier a subi des applications de logiciels. Les résultats ont montré qu'il n'y avait pas de différence significative entre les performances des deux groupes. Cependant, le groupe expérimental a fait preuve d'attitudes positives envers l'ordinateur et les programmes de logiciels. 相似文献
