Interfaces to databases have traditionally been designed as single-user systems that hide other users and their activity. This paper aims to show that collaboration is an important aspect of searching online information retrieval (IR) systems that requires explicit computerised support. A number of systems offering varied approaches to supporting collaboration are surveyed and a structure for analysing the various aspects of collaboration is applied. The dominant form of collaboration in digital libraries is likely to be remote and asynchronous. Collaborative work in the digital library requires that both the search product and the search process can be captured and communicated. The ARIADNE system is introduced as an example of computerised support for collaboration between browsers.  相似文献   

Real-time processing of social media with SENTINEL: A syndromic surveillance system incorporating deep learning for health classification     

Ovidiu Șerban  Nicholas Thapen  Brendan Maginnis  Chris Hankin  Virginia Foot 《Information processing & management》2019,56(3):1166-1184

Interest in real-time syndromic surveillance based on social media data has greatly increased in recent years. The ability to detect disease outbreaks earlier than traditional methods would be highly useful for public health officials. This paper describes a software system which is built upon recent developments in machine learning and data processing to achieve this goal. The system is built from reusable modules integrated into data processing pipelines that are easily deployable and configurable. It applies deep learning to the problem of classifying health-related tweets and is able to do so with high accuracy. It has the capability to detect illness outbreaks from Twitter data and then to build up and display information about these outbreaks, including relevant news articles, to provide situational awareness. It also provides nowcasting functionality of current disease levels from previous clinical data combined with Twitter data.The preliminary results are promising, with the system being able to detect outbreaks of influenza-like illness symptoms which could then be confirmed by existing official sources. The Nowcasting module shows that using social media data can improve prediction for multiple diseases over simply using traditional data sources.  相似文献   

Two balls is too many: stadium performance and queerness among Portland’s Rose City Riveters supporters club     

Chris W. Henderson 《Sport in Society》2018,21(7):1031-1046

Abstract

Portland, Oregon’s Rose City Riveters is the largest independent organized supporters group for a women’s soccer team in the world. They support Portland Thorns with an organized, expressive and organic performance of songs, musical instruments and displays that envelopes the entire stadium. Utilizing ethnographic subject-centred methods, this empirical study argues that the group’s performance reflects two different performance lineages, organically organized transnational soccer fandom on one hand and disidentifying queer public performance on the other. This paper explores how different elements of these lineages overlap in the Riveters’ performance to disrupt, negotiate and resist the dominant ideologies of hyper-masculinity and heteronormative femininity that shape professional soccer in the United States.  相似文献   

Selective immigration policies as screening devices and the immigrant–native educational achievement gap     

Chris Sakellariou 《Educational Research and Evaluation》2018,24(6-7):394-416

The literature on the immigrant–native educational achievement gap is suggestive of a better performance of immigrant students in countries practising selective immigration policies. However, the origin of such differences has not been investigated. I considered both important observed characteristics as well as the role of unobservables in the formation of immigrant–native achievement differences in 4 selective immigration countries. I found that, if the comparison is between selective immigration countries as a group and other European/Organisation for Economic Co-operation and Development (OECD) countries, immigrant students in selective immigration countries perform better. However, the results are heterogeneous and different conclusions apply to each of the 4 countries. The findings are discussed in the context of successful immigration policies as screening devices, which induce a self-selection of immigrants with transferable and adaptive skills. Potentially important are also institutional differences with respect to how inclusionary and conducive to the integration of immigrants into the host country policies are.  相似文献   

The Reliability of Free School Meal Eligibility as a Measure of Socio-Economic Disadvantage: Evidence from the Millennium Cohort Study in Wales     

Chris Taylor 《British Journal of Educational Studies》2018,66(1):29-51

Over the last 20 years, the use of administrative data has become central to understanding pupil attainment and school performance. Of most importance has been its use to robustly demonstrate the impact of socio-economic status (SES) on pupil attainment. Much of this analysis in England and Wales has relied on whether pupils are eligible for free school meals (eFSM). However, very little is known about the validity of this measure as a proxy for SES. Using a recent major birth cohort study, this paper examines the relationship between pupils’ eFSM and their more detailed socio-economic circumstances.  相似文献   

Premier League academy soccer players’ experiences of competing in a tournament bio-banded for biological maturation

Individual differences in the growth and maturation have been shown to impact player performance and development in youth soccer. This study investigated Premier League academy players’ experiences of participating in a tournament bio-banded for biological maturation. Players (N = 66) from four professional soccer clubs aged 11 and 14 years and between 85–90% of adult stature participated in a tournament. Players competed in three 11 vs 11 games on a full size pitch with 25-min halves. Sixteen players participated in four 15-min focus groups and were asked to describe their experiences of participating in the bio-banded tournament in comparison to age group competition. All players described their experience as positive and recommended the Premier League integrate bio-banding into the existing games programme. In comparison to age-group competitions, early maturing players described the bio-banded games more physically challenging, and found that they had to adapt their style of play placing a greater emphasis on technique and tactics. Late maturing players considered the games to be less physically challenging, yet appreciated the having more opportunity to use, develop and demonstrate their technical, physical, and psychological competencies. Bio-banding strategies appear to contribute positively towards the holistic development of young soccer players.  相似文献   

Comment on “Football-specific fitness testing: adding value or confirming the evidence?”     

Christopher Carling  Dave Collins 《Journal of sports sciences》2014,32(13):1206-1208

Abstract

The recent point–counter-point exchange arising from the article by Mendez-Villanueva and Buchheit (2013) (Football-specific fitness testing: Adding value or confirming the evidence? Journal of Sports Sciences, 31, 1503–1508) has generated an interesting debate on the real-world utility of fitness testing in professional association football (soccer). In the present authors’ opinion, this exchange could also have been placed more in the context of the physical testing and subsequent benchmark profiling of the youth player within elite academy talent identification and development processes. This point is further strengthened by the current media debate at the time of writing on the development of elite youth football players in England and the Elite Player Performance Plan or EPPP (The Premier League. (2011). Elite Player Performance Plan. London: Author) published by the English Premier League as part of a vision for the future development of youth football in the League and throughout the English professional game. The EPPP recommends the implementation of a national database to enable comparison of Academy player performances against national physical testing “benchmark” profiles. In continuing the above debate, this letter questions the real-world utility and potential pitfalls of nationwide athletic benchmark profiling programmes for elite youth football.  相似文献   

Introducing Information and Communication Technologies into Schools: The blurring of boundaries     

Tony Lawson  Chris Comber 《British Journal of Sociology of Education》2000,21(3):419-433

This article considers the impact of Superhighways technology on schools in the UK, in terms of the debate concerning the development of the conditions of postmodernity. In particular, it charts how the collapse of boundaries associated with postmodernism may have affected traditional divisions within schooling, following the introduction of broadband connectivity and Internet capability to schools and colleges. The authors review the broad approaches taken to the introduction of new technologies, such as the Utopian and Dystopian, transformative and incrementalist. By drawing upon the findings of the Education Departments' Superhighways Initiative, the authors explore the effects of new information and communication technologies on a number of traditional boundaries, including those between curriculum subjects, between pupils and teachers, and, more generally, traditional conceptions of space and time. The article concludes that, although initial indications suggest that the impact of Superhighways capability may be a transformative one, the effect on boundaries is mixed. While some boundaries such as those of space and time seem to be dissolving, others such as the division between academic subjects are much more resistant.  相似文献

A Brief History of Timing: the impact of the National Literacy Strategy on the marketing and publishing of resources to support literacy teaching     

Prue Goodwin  Chris Routh 《Literacy》2000,34(3):119-123

Since the announcement of the National Literacy Project in April 1996, publishers of children’s books and teaching materials have been keen to provide appropriate materials for use in the literacy hour. With the new government in 1997 came generous funding for books and publishers were quick to respond in terms of marketing and new publications. Lack of time and training to assimilate the new approaches caused many teachers to rely on materials to show them how to teach. While this reliance on materials underlines the ongoing need for teachers to be updated about resources, time to become more knowledgeable and confident about practice remains paramount.  相似文献
