Understanding and conceptualising the document triage process through information seekers' visual and navigational attention

Information, is a valuable commodity and its effective use is a vital part of everyday life. With the advancements of the internet and the increasing accessibility to it, the location of information is no longer the primary concern of information seekers. Digitisation techniques have made a wide variety of documents available on-line, and more and more publications are being published in electronic form simultaneously to their physical counterpart. The largest challenge currently facing information seekers is that of locating the correct information from the abundance available to them. Whenever a search query is made, the user is inundated with multiple options of documents to choose from. These documents are all deemed to have some relevance to the query produced by using an information retrieval algorithm. Thus far, automatic support has only been provided until the document retrieval level. The user is then left to search through the result set, mostly unaided, by the system he is using. In order to facilitate support for the users, a solid understanding of the information seeker's behaviours during this triage process is vital. Thus far, research into the behaviour of information seekers during the specific triage behaviour is limited. Even more limited however, is the evidence reporting the visual attention of the users. Since the triage process is highly visual, this important element need to be thoroughly evidence before accurately conceptualising the entire process. For this reason, this thesis aims to investigate the visual attention of information seekers during the document triage process. This will inform the modelling and conceptualisation of information seekers' behaviour during triage. In turn, this can be used to inform the design of supportive software. The thesis contains a review of related research and identifies the gaps that needs further investigation. From these, a series of user studies are then conducted on document triage. These in turn, facilitate the formulation and discussion of 2 document triage models and measurements to record the effectiveness of document triage. We study the visual attention of information seekers in four lab based studies, eliciting their exact gaze and focus details. We expand current research in the information seeking domain by reporting on findings from users' triage activities on small screen devices and when under time constraints. Furthermore, a high level diary study, gives us richer data on participants' triage activities over a larger period of time in their natural surroundings. All the studies are brought together to elicit requirements and measurements to understand system and user efficiency during each stage of the triage process

Theory and practice in visual interfaces for semi-structured document discovery and selection

With the increase in electronic publications, and indeed the availability of existing publications in digital form, as well as the encouragement of open access publication, comes a challenge. That challenge is to create assistive software to aid in the discovery and selection of relevant documents to one’s information need. Visual interfaces have begun to address the need of information seekers in finding publications and wading through the large result sets that are returned from search engines. There is currently, little evidence to suggest that these interfaces are based on systematic research on requirements. In this article, we examine areas which contribute to the theory and practice of visual interfaces directly relating to the discovery and selection of publications. We bring together work from different fields in a targeted approach to assist the future creation of these interfaces

Evolutionary Design of Search and Triage Interfaces for Large Document Sets

This dissertation is concerned with the design of visual interfaces for searching and triaging large document sets. Data proliferation has generated new and challenging information-based tasks across various domains. Yet, as the document sets of these tasks grow, it has become increasingly difficult for users to remain active participants in the information-seeking process, such as when searching and triaging large document sets. During information search, users seek to understand their document set, align domain knowledge, formulate effective queries, and use those queries to develop document set mappings which help generate encounters with valued documents. During information triage, users encounter the documents mapped by information search to judge relevance to information-seeking objectives. Yet, information search and triage can be challenging for users. Studies have found that when using traditional design strategies in tool interfaces for search and triage, users routinely struggle to understand the domain being searched, apply their expertise, communicate their objectives during query building, and assess the relevance of search results during information triage. Users must understand and apply domain- specific vocabulary when communicating information-seeking objectives. Yet, task vocabularies typically do not align with those of users, especially in tasks of complex domains. Ontologies can be valuable mediating resources for bridging between the vocabularies of users and tasks. They are created by domain experts to provide a standardized mapping of knowledge that can be leveraged both by computational- as well as human-facing systems. We believe that the activation of ontologies within user-facing interfaces has a potential to help users when searching and triaging large document sets, however more research is required

Digital transformation in the german healthcare industry : an analysis of the video consultation (teledoctor) and how it can shape the german healthcare industry

The healthcare industry is currently undergoing a digital transformation. Thereby, efficiency and accessibility between physicians and patients shall be improved by innovative care and treatment concepts. One of these innovative concepts is the telemedicine and in particular the video consultation which enables a location independent treatment of patients through information and communication technology. However, this kind of digital medical treatment is currently not properly available in Germany. Therefore, this exploratory study deals with the current status and potential of video consultation in Germany, the challenges and derives potential impacts of the video consultation. The findings reveal that the legal framework of the video consultation, inappropriate reimbursement, acceptance within patients and physicians and no adequate expanded telematic infrastructure are the main challenges that hinder the further development of the video consultation. At the same time, an educated guess showed that a potential size of video consultation based on physicians and patient’s acceptance exists. The video consultation and its connected features will shift the physical based healthcare system to a more online focused and patient centered system which in return will affect all involved stakeholder. Patients will have better access to medical care and physicians will have more efficient practice processes and more flexible working models. In order to adapt to the digital change of society, physicians should provide VC and healthcare insurance companies should support it.A indústria da saúde está, atualmente, a passar por uma transformação digital. Deste modo, a eficiência e a acessibilidade entre médicos e pacientes serão melhoradas através de conceitos inovadores de cuidados e tratamentos. Um destes conceitos inovadores é a telemedicina e, em particular, a videoconferência, que permite um tratamento independente da localização dos doentes através das tecnologias da informação e da comunicação. No entanto, este tipo de tratamento médico digital não está actualmente disponível de forma adequada na Alemanha. Portanto, este estudo exploratório lida com a situação atual e o potencial da consulta por vídeo na Alemanha, os desafios e os potenciais impactos da consulta por vídeo. Os resultados revelam que a estrutura legal da consulta em vídeo, o reembolso inadequado, a aceitação pelos pacientes e médicos e a falta de infraestrutura telemática expandida adequada são os principais desafios que dificultam o desenvolvimento futuro da consulta em vídeo. Ao mesmo tempo, uma suposição esclarecida mostrou que existe um tamanho potencial de consulta por vídeo baseado na aceitação dos médicos e pacientes. A consulta em vídeo e os recursos conectados mudam o sistema de saúde com base física para um sistema mais focado online e centrado no paciente, o que afetará todas as partes interessadas envolvidas. Os pacientes terão melhor acesso aos cuidados médicos e os médicos terão processos práticos mais eficientes e modelos de trabalho mais flexíveis. A fim de se adaptar à mudança digital da sociedade, os médicos devem fornecer VC e as companhias de seguros de saúde devem apoiá-la

Enhancing choice? The role of technology in the career support market

This report explores the role that technology has played in the development of the career support market. This market is conceived broadly to include all possible resources that individuals might draw upon to support them in their career development. A key element is the role that is played by public-sector career services and by careers professionals; though these resources are supplemented by services paid for in a wide range of ways and delivered by a range of professionals and non-professionals.UKCE

The emergency care of young people who self-harm: an exploration of attitudes towards young people who self-harm and the care they receive from practitioners working in pre-hospital and hospital based emergency services

Aim: Using a mixed methods approach, this thesis seeks to explore the attitudes of emergency care staff towards young people (aged 12− 18 years) who self-harm and to gain an understanding of the basis of attitudes that exist. Background: This thesis has drawn on Strauss et al’s (1964), concept of the hospital as a negotiated order, a perspective that has latterly been applied to the organisation of hospital A&E services (Sbaih1997a&b 1998a&b, 2001, 2002). As the fundamental premise of emergency care work is the rapid assessment of patients’ needs, categorisation is an essential element of this work. This thesis therefore also draws on the sociological theories which have examined the categorisation of patients as ‘good’ or ‘bad’, as earlier sociological work has clearly demonstrated that practitioners working in emergency services judge patients based on their reasons for accessing the service (Roth 1972, Jeffery 1979, Dingwall & Murray 1983); patients who self-harm are amongst those adversely judged. However the extent to which these categorisations extend to young people was not wholly clear. Findings from earlier research that had considered this were inconclusive and inconsistent (Dingwall & Murray 1983, White 2002). Methods: A mixed methods approach, using a triangulation convergent design was employed. Staff employed in four emergency departments in South East London and five London Ambulance complexes that served these departments were surveyed; data from 143 questionnaires were analysed using SPSS. Qualitative data were obtained through semi-structured interviews with 12 practitioners, seven nurses and five paramedics, with thematic analysis undertaken. The two data sets were integrated and analysed to identify where the two data sets were consistent and whether/where discrepancies existed. Results: Findings from this study indicate that age, i.e. being a young person, does influence attitudes towards self-harm. Young people are less adversely judged as their self-harm is seen as symptom of distress, a coping mechanism or response to a stressor out with a young person’s control, thus as a consequence, attitudes towards young people who self-harm are benign. The findings lend support to previous research which has indicated that as an occupation, nurses have less positive attitudes than their peers working in emergency services. Although not statistically significant, the nurses surveyed in this study obtained lower scores on the scale used to measure attitudes than their medical and paramedical colleagues. The data from the interviews illustrated the difficulties and frustration the nurses faced in managing the care of young people who self-harm, which centred on the pressure to ‘move young people on’, pressures that were exacerbated by the need to do this within four hours. The paramedics interviewed did not face these challenges. Nurses faced considerable difficulty in securing admission to a children’s ward; the accounts of the nurse interviewees suggested that their ward colleagues expected and anticipated that young people who had self-harmed would be challenging in terms of their behaviours, whereas no such expectation existed with other adolescent patients. To this end the diagnostic label of self-harm had negative connotations Conclusions: The findings from this study have extended existing knowledge in relation to practitioners’ attitudes towards young people who self-harm, providing as they do an insight into how young peoples’ immaturity and diminished agency, contribute to the framing of young people as vulnerable, thus their self-harming behaviour is less adversely judged. A negotiated order perspective remains a relevant lens through which to analyse and explore the organisation of hospital services and specifically the work of the A&E department; the findings of the research presented in this thesis have revealed how young people who self-harm, through both their actual and perceived behaviours, disrupt the organisation of children’s accident and emergency care, thereby distorting its ‘shape’. The ambiguity of adolescence as a life-stage is reflected in the attitudes and perceptions of the study participants and is also reflected in health policy and guidelines, which is particularly exemplified by inconsistency in how the emergency care needs of young people between the ages of 16– 18 years generally, and young people who self-harm specifically, are addressed. This inconsistency and ambiguity in turn serves to impede young people’s progress through emergency services following an episode of self-harm
