The Promise of the Transparency Culture     

Ester Appelgren  Ramón Salaverría 《Journalism Practice》2018,12(8):986-996

In 2013, with the introduction of the Transparency Law in Spain, a number of Spanish newsrooms started working with data journalism methods. In Sweden, which has one of the oldest Freedom of Information acts in the world, newsrooms invested in the skill development of data journalism at approximately the same time. Because previous research suggests that access to public data has been one of the key driving forces for the development of data journalism worldwide, it is important to understand how legislation is actually shaping the practice of data journalism. Based on a survey of 66 key informants in Spain and Sweden and ten in-depth interviews with data journalists from five media companies in each country, we conducted a comparative study, building on the frameworks of media systems to explore data journalism practices in these two countries. The differences found indicate that the national and EU legislation in both nations shape journalistic strategies for accessing data, turning journalists at times into activists fighting for the right to access public data. Beyond the law, data journalists advocate for a transparency culture among the civil servants, in order to secure public accountability.  相似文献

News Sources and Follow-up Communication

For sports actors, social media provide the opportunity to bypass sports journalism's gatekeeping function and to disseminate sports-related information to target groups directly. Thus, social media have been conceptualized as a competitor to journalism. We argue that the relation is much more diverse. We differentiate between competitive, integrative, and complementary facets of the relationship between sports journalism and social media. Our study focuses on complementarity and analyzes how far social and mainstream media serve as sources for each other. Therefore, we combine an online survey among 122 German sports journalists, an analysis of the Twitter networks of German sports journalists during the Winter Olympics 2014, and a content analysis of the most popular news items in social media. Results suggest that sports journalists perceive social media accounts of athletes as beneficial news sources, especially to gather inside information. Huge sports events influence the social media activities of sports journalists as they tend to have stronger connections to athletes at these times. Whereas social media appear to be significant sources for sports journalism, sports media content receives little attention in social media. However, our results indicate that sports journalism and social media indeed maintain a complementary relation.  相似文献   

Environmental Sensitivity among Wisconsin High School Students   总被引：1，自引：2，他引：1  

Daniel J. Sivek 《Environmental Education Research》2002,8(2):155-170

A two-phase study was conducted to assess influences on environmental sensitivity (ES) in Wisconsin high school students. Phase I employed a focus group methodology; phase II employed a paper survey. Three categories of influences emerged from phase I: environmental, role model, and personality. Other results were consistent between both study phases. The influence most frequently cited by students as most important was time spent outdoors. The second most frequently mentioned influence was male teachers. The most frequently mentioned trait of role models was that they were 'friendly/personable'. A profile of environmentally sensitive high school students was developed.  相似文献   

Does Student Effort Respond to Incentives? Evidence from a Guaranteed College Admissions Program     

Daniel M. Leeds  Isaac McFarlinJr.  Lindsay Daugherty 《Research in higher education》2017,58(3):231-243

This paper studies the effects of guaranteed college admission on student effort and achievement. In 1997, Texas enacted the “Top Ten Percent” law, which guarantees admission to any public college for students in the top ten percent of their high school class. In practice, eligible students become aware of their admission status at the end of their junior year in high school—more than 1 year prior to attending college. We use data from a large, urban school district and regression discontinuity methods to test for effects on effort. Our preferred estimates show that students who barely qualify for the admissions guarantee earn marginally lower grades and take fewer advanced courses in their senior year compared to students who do not qualify for guaranteed admission and learn their status in the final senior year term. We find qualitatively similar results when limiting our sample to finer bandwidths, although the estimates are imprecise.  相似文献   

On the relationship between society and higher education: what path should we take?     

Laura Márquez-Ramos  Estefanía Mourelle 《Distance Education》2018,39(1):19-36

Abstract

The current network society, with its primacy of information and communication technologies, is challenging the higher education model. The needs and expectations of today’s students differ from those of students in the past, and educational practices should adapt to modern times. But what changes will we see in the relationship between societal transformation and the higher education system? In this research paper, we set out a quantum-based approach in order to analyze this relationship and to advance the understanding about the role that distance education will play in the future. Under this perspective, we provide an illustration that allows for the representation and evaluation of future scenarios.  相似文献   

The information needs of occupational therapy students: a case study          下载免费PDF全文

Jane Morgan‐Daniel  Hugh Preston 《Health information and libraries journal》2017,34(2):165-170

This article summarises a case study on the information needs of Masters level Occupational Therapy 5 (OT) students at one English university. A mixed methods questionnaire was used to explore motivators for information‐seeking, preferred information resources and barriers inhibiting the satisfaction of information needs. Thirteen recommendations for practice were formulated, focusing on how information professionals can best facilitate OT students’ learning and evidence‐based research skills in preparation for clinical practice. The study was completed by Jane Morgan‐Daniel, who received a Distinction for her work from Aberystwyth University, where she graduated with an MSC in Information and Library Studies in December 2016. She has written this article together with her dissertation supervisor, Hugh Preston. A. M.  相似文献   

Identifying top relevant dates for implicit time sensitive queries

Despite a clear improvement of search and retrieval temporal applications, current search engines are still mostly unaware of the temporal dimension. Indeed, in most cases, systems are limited to offering the user the chance to restrict the search to a particular time period or to simply rely on an explicitly specified time span. If the user is not explicit in his/her search intents (e.g., “philip seymour hoffman”) search engines may likely fail to present an overall historic perspective of the topic. In most such cases, they are limited to retrieving the most recent results. One possible solution to this shortcoming is to understand the different time periods of the query. In this context, most state-of-the-art methodologies consider any occurrence of temporal expressions in web documents and other web data as equally relevant to an implicit time sensitive query. To approach this problem in a more adequate manner, we propose in this paper the detection of relevant temporal expressions to the query. Unlike previous metadata and query log-based approaches, we show how to achieve this goal based on information extracted from document content. However, instead of simply focusing on the detection of the most obvious date we are also interested in retrieving the set of dates that are relevant to the query. Towards this goal, we define a general similarity measure that makes use of co-occurrences of words and years based on corpus statistics and a classification methodology that is able to identify the set of top relevant dates for a given implicit time sensitive query, while filtering out the non-relevant ones. Through extensive experimental evaluation, we mean to demonstrate that our approach offers promising results in the field of temporal information retrieval (T-IR), as demonstrated by the experiments conducted over several baselines on web corpora collections.  相似文献   

Statistical biases in Information Retrieval metrics for recommender systems     

Alejandro?BellogínEmail authorView author&#;s OrcID profile  Pablo?Castells  Iván?Cantador 《Information Retrieval》2017,20(6):606-634

There is an increasing consensus in the Recommender Systems community that the dominant error-based evaluation metrics are insufficient, and mostly inadequate, to properly assess the practical effectiveness of recommendations. Seeking to evaluate recommendation rankings—which largely determine the effective accuracy in matching user needs—rather than predicted rating values, Information Retrieval metrics have started to be applied for the evaluation of recommender systems. In this paper we analyse the main issues and potential divergences in the application of Information Retrieval methodologies to recommender system evaluation, and provide a systematic characterisation of experimental design alternatives for this adaptation. We lay out an experimental configuration framework upon which we identify and analyse specific statistical biases arising in the adaptation of Information Retrieval metrics to recommendation tasks, namely sparsity and popularity biases. These biases considerably distort the empirical measurements, hindering the interpretation and comparison of results across experiments. We develop a formal characterisation and analysis of the biases upon which we analyse their causes and main factors, as well as their impact on evaluation metrics under different experimental configurations, illustrating the theoretical findings with empirical evidence. We propose two experimental design approaches that effectively neutralise such biases to a large extent. We report experiments validating our proposed experimental variants, and comparing them to alternative approaches and metrics that have been defined in the literature with similar or related purposes.  相似文献
