Auditory distraction in memory tasks: Can it be controlled?

Irrelevant sound accompanying the processes of encoding and retrieval of verbal events impairs memory performance. However, the degree of impairment is highly dependent on a range of factors. Some of them lie outside rememberers’ control, like the semantic content of distracting sound or the nature of a test used to assess memory. Others, like a strategy used to encode memoranda, rest under control of the rememberer. In this paper the factors that modulate memory impairment are outlined and discussed in terms of multiple mechanisms contributing to memory impairment under auditory distraction. The mechanisms of a capture of attention by distraction, interference of automatic seriation of distraction and voluntary seriation of memoranda, semantic inhibition of distraction, and blocking of memoranda by semantically related distracters are described. Results that demonstrate how these mechanisms determine memory impairment under auditory distraction are also discussed. Particular attention is devoted to the possibility of voluntary control over the workings of these mechanisms and the conditions under which the negative impact of auditory distraction upon memory performance could be minimised.

It's all about climate change, stupid! Exploring the relationship between environmental law and climate law

This comment analyses the relationship between climate law and environmental law. It examines this relationship from both a normative and a descriptive point of view. Normatively, it brings together various strands from some of the existing literature to form an overall model of the relationship—looking at ‘crowding out’, ‘crowding in’, ‘climate exceptionalism’ and adding in ‘climate unexceptionalism’. In descriptive terms, it considers, inter alia, ‘super wickedness’, instruments and governance, mitigation and adaptation.

It is always on your mind: experiences and perceptions of falling of older people and their carers and the potential of a mobile falls detection device

Background. Falls and fear of falling present a major risk to older people as both can affect their quality of life and independence. Mobile assistive technologies (AT) fall detection devices may maximise the potential for older people to live independently for as long as possible within their own homes by facilitating early detection of falls. Aims. To explore the experiences and perceptions of older people and their carers as to the potential of a mobile falls detection AT device. Methods. Nine focus groups with 47 participants including both older people with a range of health conditions and their carers. Interviews were audio recorded, transcribed verbatim, and thematically analysed. Results. Four key themes were identified relating to participants’ experiences and perceptions of falling and the potential impact of a mobile falls detector: cause of falling, falling as everyday vulnerability, the environmental context of falling, and regaining confidence and independence by having a mobile falls detector. Conclusion. The perceived benefits of a mobile falls detector may differ between older people and their carers. The experience of falling has to be taken into account when designing mobile assistive technology devices as these may influence perceptions of such devices and how older people utilise them.

Evaluating business value of IT towards optimisation of the application portfolio

Information technology has become heavily embedded in business operations. As business needs change over time, IT applications are expected to continue providing required support. Whether the existing IT applications are still fit for the business purpose they were intended or new IT applications should be introduced, is a strategic decision for business, IT and business-aligned IT. In this paper, we present a method which aims to analyse business functions and IT roles, and to evaluate business-aligned IT from both social and technical perspectives. The method introduces a set of techniques that systematically supports the evaluation of the existing IT applications in relation to their technical capabilities for maximising business value. Furthermore, we discuss the evaluation process and results which are illustrated and validated through a real-life case study of a UK borough council, and followed by discussion on implications for researchers and practitioners.

The climate change–infectious disease nexus: is it time for climate change syndemics?

Conceptualizing climate as a distinct variable limits our understanding of the synergies and interactions between climate change and the range of abiotic and biotic factors, which influence animal health. Frameworks such as eco-epidemiology and the epi-systems approach, while more holistic, view climate and climate change as one of many discreet drivers of disease. Here, I argue for a new paradigmatic framework: climate-change syndemics. Climate-change syndemics begins from the assumption that climate change is one of many potential influences on infectious disease processes, but crucially is unlikely to act independently or in isolation; and as such, it is the inter-relationship between factors that take primacy in explorations of infectious disease and climate change. Equally importantly, as climate change will impact a wide range of diseases, the frame of analysis is at the collective rather than individual level (for both human and animal infectious disease) across populations.

What it means to stay: reterritorialising the Black Atlantic in Erna Brodber's writing of the local

The emphasis on migratory subjectivities within postcolonial studies has come from many directions—Bhabha, Gilroy, Appadurai, Boyce Davies—and their convergence has created a critical practice in which diaspora studies takes centre stage. More specifically the way in which the Caribbean person is given emblematic status as the metropolitan migrant is made clear in James Clifford's declaration that ‘We are all Caribbeans now…in our urban archipelagos'. This paper examines the serious impact on the critical reception of Caribbean writings that has been made as a result of the fact that metropolitan diasporas are now the privileged places in which to be properly ‘postcolonial’. It is my aim to show how Erna Brodber's culturally specific studies have enormous value in the face of the more general and flattened enunciations of diaspora and creolisation which are being circulated at a theoretical level. I shall look at two fairly recent pieces of writing by Brodber: a pamphlet entitled ‘The people of my Jamaican village (1817 – 1948)’ and an essay entitled ‘Where are all the others?’ in the book Caribbean Creolisation1

Towards a framework for managing IT-enabled change, sourcing and governance

In the resource-based view, organisations are represented by the sum of their physical, human and organisational assets, resources and capabilities. Operational capabilities maintain the status quo and allow an organisation to execute their existing business. Dynamic capabilities, otherwise, allow an organisation to change this status quo including a change of the operational ones. Competitive advantage, in this context, is an effect of continuously developing and reconfiguring these firm-specific assets through dynamic capabilities. Deciding where and how to source the core operational capabilities is a key success factor. Furthermore, developing its dynamic capabilities allows an organisation to effectively manage change its operational capabilities. Many organisations are asserted to have a high dependency on - as well as a high benefit from - the use of information technology (IT), making it a crucial and overarching resource. Furthermore, the IT function is assigned the role as a change enabler and so IT sourcing affects the capability of managing business change. IT sourcing means that organisations need to decide how to source their IT capabilities. Outsourcing of parts of the IT function will also outsource some of the IT capabilities and therefore some of the business capabilities. As a result, IT sourcing has an impact on the organisation's capabilities and consequently on the business success. And finally, a turbulent and fast moving business environment challenges organisations to effectively and efficiently managing business change. Our research builds on the existing theory of dynamic and operational capabilities by considering the interdependencies between the dynamic capabilities of business change and IT sourcing. Further it examines the decision-making oversight of these areas as implemented through IT governance. We introduce a new conceptual framework derived from the existing theory and extended through an illustrative case study conducted in a German bank. Under a philosophical paradigm of constructivism, we collected data from eight semi-structured interviews and used additional sources of evidence in form of annual accounts, strategy papers and IT benchmark reports. We applied an Interpretative Phenomenological Analysis (IPA), which emerged the superordinate themes for our tentative capabilities framework. An understanding of these interdependencies enables scholars and professionals to improve business success through effectively managing business change and evaluating the impact of IT sourcing decisions on the organisation's operational and dynamic capabilities.

The agile governance of business IT projects

Organisations typically define and execute their selected strategy by developing and managing a portfolio of projects. The governance of this portfolio has proved to be a major challenge, particularly for large organisations. Executives and managers face even greater pressures when the nature of the strategic landscape is uncertain. This paper explores approaches for dealing with different levels of certainty in business IT projects and provides a contingent governance framework. Historically business IT projects have relied on a structured sequential approach, also referred to as a waterfall method. There is a distinction between the development stages of a solution and the management stages of a project that delivers the solution although these are often integrated in a business IT systems project. Prior research has demonstrated that the level of certainty varies between development projects. There can be uncertainty on what needs to be developed and also on how this solution should be developed. The move to agile development and management reflects a greater level of uncertainty often on both dimensions and this has led the adoption of more iterative approaches. What has been less well researched is the impact of uncertainty on the governance of the change portfolio and the corresponding implications for business executives. This paper poses this research question and proposes a govemance framework to address these aspects. The governance framework has been reviewed in the context of a major anonymous organisation, FinOrg. Findings are reported in this paper with a focus on the need to apply different approaches. In particular, the governance of uncertain business change is contrasted with the management approach for defined IT projects. Practical outputs from the paper include a consideration of some innovative approaches that can be used by executives. It also investigates the role of the business change portfolio group in evaluating and executing the appropriate level of governance. These results lead to recommendations for executives and also proposed further research.

Towards cost-sensitive adaptation: when is it worth updating your predictive model?

Our digital universe is rapidly expanding,more and more daily activities are digitally recorded, data arrives in streams, it needs to be analyzed in real time and may evolve over time. In the last decade many adaptive learning algorithms and prediction systems, which can automatically update themselves with the new incoming data, have been developed. The majority of those algorithms focus on improving the predictive performance and assume that model update is always desired as soon as possible and as frequently as possible. In this study we consider potential model update as an investment decision, which, as in the financial markets, should be taken only if a certain return on investment is expected. We introduce and motivate a new research problem for data streams ? cost-sensitive adaptation. We propose a reference framework for analyzing adaptation strategies in terms of costs and benefits. Our framework allows to characterize and decompose the costs of model updates, and to asses and interpret the gains in performance due to model adaptation for a given learning algorithm on a given prediction task. Our proof-of-concept experiment demonstrates how the framework can aid in analyzing and managing adaptation decisions in the chemical industry.

Is it still King Lear? English teachers and the e-reader phenomenon

E-reading devices such as the Kindle have rapidly secured a significant place in a number of societies as at least one major platform for reading.To some extent they are part of the overarching move towards a fully digitised world, but they have a distinctiveness in being deliberately‘book-like’. Teachers generally have some suspicion towards ‘New Media’, especially when it challenges their established practice. This chapter reports on a survey of English teachers in England to gauge their reactions to e-readers, both personally and professionally, and describes their speculations about the place of e-readers in schools in the future. There is a mixed reaction with some teachers concerned about the demise of the book and the potential negative impact on reading. However, the majority welcome e-readers as a dynamic element within the reading environment with particular potential to enthuse reluctant readers and those with special or linguistic needs. They also, some grudgingly, view the fact that reading using this form of technology appeals to the ‘egeneration’ and may succeed in making reading ‘cool’. This form of technology is, ironically [given that it appears to threaten traditional books], likely to be rapidly adopted in classrooms.

The IT outsourcing market-place: vendors and their selection

This paper focuses on outsourcing vendors, their characteristics and the vendor selection process. It draws on current research and two research studies, one specifi- cally examining outsourcing vendors and the other examining vendor-client issues. We first outline the development of the market for the outsourcing of information technology/information systems services and activities, then detail the characteristics of different types of vendor companies and their competitive positions, before providing a client perspective to the issue of vendor selection.

Is it me? Self-recognition bias across sensory modalities and its relationship to autistic traits

Background Atypical self-processing is an emerging theme in autism research, suggested by lower self-reference effect in memory, and atypical neural responses to visual self-representations. Most research on physical self-processing in autism uses visual stimuli. However, the self is a multimodal construct, and therefore, it is essential to test self-recognition in other sensory modalities as well. Self-recognition in the auditory modality remains relatively unexplored and has not been tested in relation to autism and related traits. This study investigates self-recognition in auditory and visual domain in the general population and tests if it is associated with autistic traits. Methods Thirty-nine neurotypical adults participated in a two-part study. In the first session, individual participant’s voice was recorded and face was photographed and morphed respectively with voices and faces from unfamiliar identities. In the second session, participants performed a ‘self-identification’ task, classifying each morph as ‘self’ voice (or face) or an ‘other’ voice (or face). All participants also completed the Autism Spectrum Quotient (AQ). For each sensory modality, slope of the self-recognition curve was used as individual self-recognition metric. These two self-recognition metrics were tested for association between each other, and with autistic traits. Results Fifty percent ‘self’ response was reached for a higher percentage of self in the auditory domain compared to the visual domain (t = 3.142; P < 0.01). No significant correlation was noted between self-recognition bias across sensory modalities (τ = −0.165, P = 0.204). Higher recognition bias for self-voice was observed in individuals higher in autistic traits (τ AQ = 0.301, P = 0.008). No such correlation was observed between recognition bias for self-face and autistic traits (τ AQ = −0.020, P = 0.438). Conclusions Our data shows that recognition bias for physical self-representation is not related across sensory modalities. Further, individuals with higher autistic traits were better able to discriminate self from other voices, but this relation was not observed with self-face. A narrow self-other overlap in the auditory domain seen in individuals with high autistic traits could arise due to enhanced perceptual processing of auditory stimuli often observed in individuals with autism.
