CHORUS Deliverable 2.1: State of the Art on Multimedia Search Engines
Based on the information provided by European projects and national initiatives related to multimedia search as well as domains experts that participated in the CHORUS Think-thanks and workshops, this document reports on the state of the art related to multimedia content search from, a technical, and socio-economic perspective.
The technical perspective includes an up to date view on content based indexing and retrieval technologies, multimedia search in the context of mobile devices and peer-to-peer networks, and an overview of current evaluation and benchmark inititiatives to measure the performance of multimedia search engines.
From a socio-economic perspective we inventorize the impact and legal consequences of these technical advances and point out future directions of research
A quantitative analysis of the impact of a computerised information system on nurses' clinical practice using a realistic evaluation framework
Objective: To explore nurses' perceptions of the impact on clinical practice of the use of a computerised hospital information system.
Design: A realistic evaluation design based on Pawson and Tilley's work has been used across all the phases of the study. This is a theory-driven approach and focuses evaluation on the study of what works, for whom and in what circumstances. These relationships are constructed as context-mechanisms-outcomes (CMO) configurations.
Measurements: A questionnaire was distributed to all nurses working in in-patient units of a university hospital in Spain (n = 227). Quantitative data were analysed using SPSS 13.0. Descriptive statistics were used for an overall overview of nurses' perception. Inferential analysis, including both bivariate and multivariate methods (path analysis), was used for cross-tabulation of variables searching for CMO relationships.
Results: Nurses (n = 179) participated in the study (78.8% response rate). Overall satisfaction with the IT system was positive. Comparisons with context variables show how nursing units' context had greater influence on perceptions than users' characteristics. Path analysis illustrated that the influence of unit context variables are on outcomes and not on mechanisms.
Conclusion: Results from the study looking at subtle variations in users and units provide insight into how important professional culture and working practices could be in IT (information technology) implementation. The socio-technical approach on IT systems evaluation suggested in the recent literature appears to be an adequate theoretical underpinning for IT evaluation research. Realistic evaluation has proven to be an adequate method for IT evaluation. (C) 2009 Elsevier Ireland Ltd. All rights reserved
Augmenting usability: cultural elicitation in HCI
This paper offers context and culture elicitation in an inter-cultural and multi-disciplinary setting of ICT design. Localised usability evaluation (LUE) is augmented with a socio-technical evaluation tool (STEM) as a methodological approach to expose and address issues in a collaborative ICT design within the Village e-Science for Life (VeSeL) project in rural Kenya. The paper argues that designers need to locally identify context and culture in situ and further explicate their implications through the design process and at the global level. Stakeholdersâ context, culture, decisions, agendas, expectations, disciplines and requirements need to be locally identified and globally evaluated to ensure a fit for purpose solution
Behavioral Approach to Information Security Policy Compliance
Information security is among the top organizational priorities. Theoretically, information security in socio-technical networks is as much of a behavioral issue as it is of a technical issue. Protection motivation theory (PMT), the dominant theory used to investigate end-user security behavior, though has shown conflicting results - primarily due to lack of contextualizing the theory to information security context from a healthcare context. In this paper, we outline a theoretically grounded conceptual model of the major factors influencing information security policy compliance. The model contextualizes the two independent variables of PMT. Threat appraisal evaluation is viewed as construal evaluation based on construal level theory, while coping appraisal evaluation is viewed as an outcome of training based on social cognitive theory. Overall, the model provides a well-grounded nomological network to better explain information security compliance behavior. The paper also outlines key managerial levers that can be used to influence end-user behavior
An Overview of the Issues in Evaluating Special Educators: Current Challenges and Recent Developments
Teachers have always been evaluated in some way; yet, current roles in the classroom have shifted to more scientific and data based approaches to teacher evaluation. These specialized approaches to teaching and evaluation have raised questions about using a single or uniform tool to assess educators. Special educators are particularly impacted by teacher evaluations since their roles require unique instructional and behavioral management skills. In addition to the range of technical and socio-emotional competencies, special educators are responsible for ensuring that all of their students\u27 learning and academic needs are met. In this backgrounder, the author first provides a brief history of special education teacher evaluation processes, then considers the complexities of special educators\u27 roles and responsibilities, and finally, interrogates special education educator evaluation within a new policy context
Assistant without Master? Some Conceptual Implications of Assistive Robotics in Health Care
The subject of âtechnical assistantsâ in inpatient care is currently being widely discussed in scientific and public circles. In many cases, though, it has become apparent that the umbrella term âassistive technologiesâ, also in the context of robotics, is very contrived. Against this background, the authors of this article reflect on the meaning of âassistanceâ in socio-technical systems, and critically review its relevance. To understand and demonstrate âassistiveâ functions, it is essential to establish a frame of reference. The re-evaluation of an empirical study of people with dementia in inpatient care has revealed the functional character of technical assistance systems. The results, however, show that the theoretical debate on the social and organisational function of âassistanceâ in these technical fields is still lacking. Therefore, the reflections in this paper may also provide some starting points for this debate

Machines and machinations: The integrated care record service in the UK national health service
This paper examines the use of Actor Network Theory (ANT) as a lens to get a better understanding of the implementation of the Integrated Care Record Service (ICRS) in the UK National Health Service (NHS). Actor Network Theory has been deployed in various environments to achieve a better understanding of the roles of not only the humans but also the artifacts that constitute, in this case, healthcare networks of services and organisations. The theory is used as a means of supporting real world interventions, providing a richer understanding of complexities involved and thereby helps management to make better decisions. This study also explores Latourâs concept of machines as machinations, whose role is to translate other actors into the network. We propose ICRS as a fruitful empirical context for the use of ANT to support decision making for actors in health care provision. Actor Network Theory (ANT) is well-suited for use in the socio-technical evaluation of IS into the ICRS project because this approach treats human and non-human actors symmetrically. This approach facilitates a more thorough examination of the ways in which information technology is enabled or restricted in social processes

Integrating information and knowledge for enterprise innovation
It has widely been accepted that enterprise integration, can be a source of socio-technical and cultural problems within organisations wishing to provide a focussed end-to-end business service. This can cause possible âstraitjacketingâ of business process architectures, thus suppressing responsive business re-engineering and competitive advantage for some companies. Accordingly, the current typology and emergent forms of Enterprise Resource Planning (ERP) and Enterprise Application Integration (EAI) technologies are set in the context of understanding information and knowledge integration philosophies. As such, key influences and trends in emerging IS integration choices, for end-to-end, cost-effective and flexible knowledge integration, are examined. As touch points across and outside organisations proliferate, via work-flow and relationship management-driven value innovation, aspects of knowledge refinement and knowledge integration pose challenges to maximising the potential of innovation and sustainable success, within enterprises. This is in terms of the increasing propensity for data fragmentation and the lack of effective information management, in the light of information overload. Furthermore, the nature of IS mediation which is inherent within decision making and workflow-based business processes, provides the basis for evaluation of the effects of information and knowledge integration. Hence, the authors propose a conceptual, holistic evaluation framework which encompasses these ideas. It is thus argued that such trends, and their implications regarding enterprise IS integration to engender sustainable competitive advantage, require fundamental re-thinking

Distance education for professional development : a case study
This thesis examines the relationship between distance education, adult learning and professional development for special education in the context of teachers' work with pupils with speech and language difficulties. Responses from students and tutors in three cohorts of a distance education course for teachers of pupils with speech and language difficulties are analysed and conclusions drawn concerning future practice in the light of changing professional needs. Qualitative methods, using questionnaires, interviews and systemic thinking activities, generate data for the analysis of course process in relation to student support, content and impact on practice. The study proposes a socio-technical systems model for planning, management and evaluation of professional development by distance education. This approach recognises that specific technical and organisational characteristics will interact with social and psychological aspects of participants' personal and professional lives
