ABSTRACT

The online environment has radically changed the way in which users consume, discover and manipulate news. The growing relevance of social media platforms and digital intermediaries for news sharing and consumption increase the likelihood of citizens to be exposed to online news even when they are not seeking it. This digital transformation fundamentally challenges the way online news use and exposure have been conceptualized and measured, affecting also to citizens’ knowledge about public affairs and politics. This article examines the factors that predict the probability to be an “incidentally exposed news user” online. Specifically, based on a representative US sample from the Pew Research Centre, this study analyses the role of media preference, use and trust. Findings indicate that beyond users’ demographics and loyalty, readers’ news preferences, uses and trust, specially of social media platforms, affect their probability to be incidentally exposed to news online. These results have important empirical and theoretical implications for understanding the connection between readers’ news consumption patterns and online exposure, intentional or incidental.  相似文献

This work presents an automated assessment tool for online distributed programming, called DSLab. It is a web-based environment that provides a transparent deployment and execution of assignments in remote computers, a transparent initialization and the possibility to add new logs by the students. DSLab has been evaluated in a real distributed learning environment by analysing students' own perceptions on their learning improvement and exploring whether students' interactions with the tool yielded a fruitful learning experience. Current research provides no evidence that the effects of such a tool have been investigated in the field of online distributed programming. Two types of analysis were performed: a quantitative analysis of data coming from students answering a questionnaire and an analysis of the log files of students' interactions with the tool. Our results showed that students perceived substantial learning improvement from the use of the automated assessment tool. Moreover, students produced fruitful interaction with the tool as soon as they achieved high familiarization and constant activity with it, which ultimately helped them improve their academic performance. Finally, the limitations of the current study and directions for future research are presented.  相似文献

In the education world, it is widely accepted that language learning is one of the pioneering disciplines in the application and use of the information and communication technologies, initially preceded by the widespread use of audiovisual resources which, finally integrated in the digital space, bring about the use of multimedia. Additionally, language learning has greatly contributed to standardizing lesson plans. They set the basis for learning design, one of the last advances in the pedagogical organization of education through the use of computers in learning managing systems. Most recently, language learning has also played an innovative role in the implementation of portfolios to education. These three perspectives address different issues for e-learning: the access to content through technology; the design of the learning initially with the help of tutors and then applying institutional frameworks for their own personal learning processes; and the edition of the resulting e-learning experience as evidence with the e-dossier, a part of the e-portfolio. Currently, the web is evolving towards its original function as the read/write web where the user, apart from accessing information, can create their own information and communicate more interactively, using technology-enhanced learning environments to integrate text and multimedia for real audiences both in the classroom and outside. Thus, taking language learning guided by the Common European Framework of Reference for Languages, the authors present here a complete e-learning system which integrates textual as well as multimedia facilities to acquire learning content, edit learning design and report learning experiences.  相似文献

There are motivation sports events attending measuring tools, although so far these instruments have only been able to provide a limited explanation for attendance, which means that more sophisticated, useful scales are required. The aim of this research is to provide more efficient tool to measure the motivations of soccer events attendance. With this aim, a 14-item scale has been developed to measure the motivations that have been identified in a comprehensive review of specialized marketing literature. This scale, was used during a soccer event, showed a good global adjustment, internal consistency and validity, and found the following four dimensions explained 67% of variance in attendance: excitement, aesthetics, escape and connections to the team and its environment.  相似文献

This article analyses moves towards good multilevel governance approaches in Vocational Education and Training (VET) as an effective way to improve VET policy making in transition and developing countries, focusing on the Southern Neighbourhood of the EU (ENPI South). The centralised approaches in public administration and to VET governance still prevail in this region. The new modes of governance applied by the EU in the policy area of education and training are based on the Open Method of Coordination (OMC). They are a source of inspiration to improve VET governance, taking into account the complexity of VET policies and systems. According to current European and international experiences, the most effective, relevant and attractive VET models and systems are demand‐driven. They rely on the effective and accountable participation of both state (national/local public actors) and non‐state VET stakeholders (e.g. employers, sectoral actors, unions) in decision‐making and policy implementation processes. This could also pave the way towards self‐governed and performance‐based VET provider institutions which would give quicker responses to rapidly changing labour market skills, competences and qualification needs. Thus, this means putting in practice more and better inclusion and effective cooperation and coordination of regional and local voices of VET actors and developing stronger social partnerships to engage employers, unions and civil society in shaping and investing in skills development. Furthermore, the role of methodological tools for VET governance is not only to provide an analytical ground to capture data and structure further policy advice. These tools can also be used as ice‐breakers to improve collaboration, inclusiveness, multi‐participation and trust‐building among policy makers as they work together on very sensitive issues such as reviewing country VET governance models, modes and institutional arrangements, and/or planning policy thinking and/or learning for implementing coordination mechanisms for VET policy making. The European Training Foundation (ETF) has implemented a methodology to map, analyse and self‐assess good multilevel governance in VET, inspired by how EU governance soft tools in education and training are being used. This methodology has been applied to the Governance for Employability in the Mediterranean (GEMM) project in the ENPI South region, which is a regional project implemented by the ETF and financed by the European Commission's Directorate General for Neighbourhood and Enlargements Negotiations (NEAR).  相似文献

Question answering (QA) is the task of automatically answering a question posed in natural language. Currently, there exists several QA approaches, and, according to recent evaluation results, most of them are complementary. That is, different systems are relevant for different kinds of questions. Somehow, this fact indicates that a pertinent combination of various systems should allow to improve the individual results. This paper focuses on this problem, namely, the selection of the correct answer from a given set of responses corresponding to different QA systems. In particular, it proposes a supervised multi-stream approach that decides about the correctness of answers based on a set of features that describe: (i) the compatibility between question and answer types, (ii) the redundancy of answers across streams, as well as (iii) the overlap and non-overlap information between the question–answer pair and the support text. Experimental results are encouraging; evaluated over a set of 190 questions in Spanish and using answers from 17 different QA systems, our multi-stream QA approach could reach an estimated QA performance of 0.74, significantly outperforming the estimated performance from the best individual system (0.53) as well as the result from best traditional multi-stream QA approach (0.60).  相似文献

The Emerging Sources Citation Index (ESCI) was created recently, in 2015, but few assessments of its journal coverage have been made. The present study tries to fill that gap by comparing its coverage with that of other international abstracting and indexing (A&I) databases. Using this measure, it is feasible to benchmark this index against the other citation indexes for acceptance criteria. We analysed 6,296 ESCI‐indexed journals, 8,889 Science Citation Index Expanded (SCIE), 3,258 Social Science Citation Index (SSCI), 1,784 Arts and Humanities Citation Index (AHCI), and 22,749 Scopus journals as indexed in July 2017 to determine their inclusion in 105 databases. We found that 19.3% of the ESCI journals are not covered by any other A&I databases, a high figure compared with only 0.5% SCIE, 0.3% SSCI, 0.3% AHCI, and 5.5% Scopus journals. This low coverage suggests that the selection criteria for ESCI journals are not consistent with the overall trend in the other classical citation indexes.  相似文献

With a focus on possible gender differences, this study used 2003–2013 data from the Survey of Doctorate Recipients to examine individual, institutional, and early employment factors that contribute to career paths of recent doctorates who enter postsecondary academic appointments. Findings showed some noteworthy differences by gender including lower salary and longer time to degree for women, but overall results indicated no strong, comprehensive evidence of a gendered path to tenure during the first decade after degree completion. Scholarly publications and activities such as research and a postdoctoral appointment in early years following degree completion were the most important contributors for both men and women. Implications for policy and planning are discussed.  相似文献
