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

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.     

The impact of limb deficiency impairment on Para swimming performance

ABSTRACT

Swimmers with limb deficiency are a core population within Para Swimming, accordingly this study examined the contribution of limb segments to race performance in these swimmers. Data were obtained for 174 male Para swimmers with limb deficiency. Ensemble partial least squares regression showed accurate predictions when using relative limb segment lengths to estimate Para swimmers’ personal best race performances. The contribution of limb segments to performance in swim events was estimated using these regression models. The analysis found swim stroke and event distance to influence the contributions of limb segments to performance. For freestyle swim events, these changes were primarily due to the increased importance of the hand, and decreased importance of the foot and shank, as the distance of the event increased. When comparing swim strokes, higher importance of the thigh and shank in the 100 m breaststroke compared with other swim strokes confirms the separate SB class. Varied contributions of the hand, upper arm and foot suggest that freestyle could also be separated from backstroke and butterfly events to promote fairer classification. This study shows that swim stroke and event distance influence the activity limitation of Para swimmers with limb deficiency suggesting classification should account for these factors.     

From autopsy to biopsy: A metacognitive view of lesson planning and teacher trainees in ELT

Lesson planning and implementation of those plans are complex and cognitively demanding for English Language Teacher trainees preparing for the profession. Many find it difficult to develop a lesson holistically and to maintain alignment across aims, procedural steps, and evaluation when planning and implementing a lesson. We attempted to address this problem by establishing a model of trainees’ action that included their deliberate metacognitive structuring of a lesson both in planning and review phases. Data from a first exploration of student thinking elicited by the model indicate positive shifts in trainees’ holistic thinking and a student-centeredness in the critical perspectives they took in both planning and review.     

‘Removing the chaos from the narrative’: preparing clinical leaders for practice development

This article explores the work of a group of ward leaders who worked in a large acute NHS Trust in London in identifying the need for practice development in their clinical settings and their own leadership development needs. The ward leaders worked with a facilitator over a period of 6 months to develop knowledge, skills and experience in leading practice developments. The project was deliberately focused on helping the ward leaders become aware of the need for change and increase their potential as leaders of changes arising from the project. The ward leaders worked with the facilitator (the lead author) over a 7-month period, utilising a variety of integrated developmental and data collection techniques. The methods employed included reflection on practice, observation of practice, discussions with practitioners, 360-degree feedback and the use of a variety of creative arts. The project was based on the narrative framework of Frank (1995), and this framework was utilised to shape the interpretation of the processes and outcomes of the project. This article thus presents the combined narrative journey of the facilitator and the participants.     

Editors' Preface: Think Global. Drink Local. National Studies with Transnational Appeal

Ad-financed TV channels are two-sided platforms where media houses provide communication from advertisers to viewers. Most media houses air several channels, some of which are particularly valuable to advertisers. At first glance, one might expect the ad volumes to be highest for the channels that are the advertisers' favorites. However, a crucial management challenge for media houses is to ensure that viewers go where the potential for raising advertising revenue is greatest. Because viewers dislike ads, we show that this implies that advertising volumes will be relatively low (and advertising prices relatively high) in such channels. Indeed, other things equal, the ad volume in a channel is inversely related to its attractiveness to the advertising market. Only if the costs of using alternative tools to attract viewers to the advertisers' favorite channels are sufficiently small will the advertising volume in channels with high demand for ads be larger than in channels with low demand for ads.     

For the record: document and record sensibilities of art conservators in the Philippines

In this article the authors present a study of the use of documents by a small group of art conservators in the Philippines. Documents are important for these conservators, but not just, or even primarily, for their role as memory devices. Also important are the functions they play in creating a sense of professional identity, for mediating the tensions created by a bureaucratically structured workplace and an occupation traditionally organised around notions of craftsmanship, and as creators of persuasive evidence for clients.
