Recording advances for neural prosthetics

An important challenge for neural prosthetics research is to record from populations of neurons over long periods of time, ideally for the lifetime of the patient. Two new advances toward this goal are described, the use of local field potentials (LFPs) and autonomously positioned recording electrodes. LFPs are the composite extracellular potential field from several hundreds of neurons around the electrode tip. LFP recordings can be maintained for longer periods of time than single cell recordings. We find that similar information can be decoded from LFP and spike recordings, with better performance for state decodes with LFPs and, depending on the area, equivalent or slightly less than equivalent performance for signaling the direction of planned movements. Movable electrodes in microdrives can be adjusted in the tissue to optimize recordings, but their movements must be automated to be a practical benefit to patients. We have developed automation algorithms and a meso-scale autonomous electrode testbed, and demonstrated that this system can autonomously isolate and maintain the recorded signal quality of single cells in the cortex of awake, behaving monkeys. These two advances show promise for developing very long term recording for neural prosthetic applications

Emotions in business-to-business service relationships

Emotion in business-to-business service relationships regarding cargo services is explored. The service relationship is characterised by mutual trust and cooperation. Contact is mainly via telephone or e-mail with some face-to-face interactions and participants providing a complex, multi-skilled seamless service. Experience rather than training plays a vital role with long-term service relationships built up and maintained. Emotional sensitivity is acquired partly by experience and a repeat customer base but mainly through a genuine desire to help and get to know others. In contrast to the view of emotional labour bringing managerial control or adverse affects to service staff, the emotion engendered by this work is authentic expression bringing personal satisfaction

Organizational learning and emotion: constructing collective meaning in support of strategic themes

Missing in the organizational learning literature is an integrative framework that reflects the emotional as well as the cognitive dynamics involved. Here, we take a step in this direction by focusing in depth over time (five years) on a selected organization which manufactures electronic equipment for the office industry. Drawing on personal construct theory, we define organizational learning as the collective re-construal of meaning in the direction of strategically significant themes. We suggest that emotions arise as members reflect on progress or lack of progress in achieving organizational learning. Our evidence suggests that invalidation – where organizational learning fails to correspond with expectations – gives rise to anxiety and frustration, while validation – where organizational learning is aligned with or exceeds expectations – evokes comfort or excitement. Our work aims to capture the key emotions involved as organizational learning proceeds

More than a cognitive experience: unfamiliarity, invalidation, and emotion in organizational learning

Literature on organizational learning (OL) lacks an integrative framework that captures the emotions involved as OL proceeds. Drawing on personal construct theory, we suggest that organizations learn where their members reconstrue meaning around questions of strategic significance for the organization. In this 5-year study of an electronics company, we explore the way in which emotions change as members perceive progress or a lack of progress around strategic themes. Our framework also takes into account whether OL involves experiences that are familiar or unfamiliar and the implications for emotions. We detected similar patterns of emotion arising over time for three different themes in our data, thereby adding to OL perspectives that are predominantly cognitive in orientation

The golden circle: A way of arguing and acting about technology in the London ambulance service

This paper analyses the way in which the London Ambulance Service recovered from the events of October 1992, when it implemented a computer-aided despatch system (LASCAD) that remained in service for less than two weeks. It examines the enactment of a programme of long-term organizational change, focusing on the implementation of an alternative computer system in 1996. The analysis in this paper is informed by actor-network theory, both by an early statement of this approach developed by Callon in the sociology of translation, and also by concepts and ideas from Latour’s more recent restatement of his own position. The paper examines how alternative interests emerged and were stabilized over time, in a way of arguing and acting among key players in the change programme, christened the Golden Circle. The story traces four years in the history of the London Ambulance Service, from the aftermath of October 1992 through the birth of the Golden Circle to the achievement of National Health Service (NHS) trust status. LASCAD was the beginning of the story, this is the middle, an end lies in the future, when the remaining elements of the change programme are enacted beyond the Golden Circle

A new conceptual framework for revenge firesetting

Revenge has frequently been acknowledged to account for a relatively large proportion of motives in deliberate firesetting. However, very little is actually known about the aetiology of revenge firesetting. Theoretical approaches to revenge-seeking behaviour are discussed. A brief review of how revenge is accounted for in existing theoretical explanations of deliberate firesetting and the known characteristics of revenge firesetters are provided. On this basis, the authors suggest, as a motive, revenge firesetting has to date been misconceptualised. A new conceptual framework is thus proposed, paying particular attention to the contextual, affective, cognitive, volitional and behavioural factors which may influence and generate a single episode of revenge firesetting. Treatment implications and suggestions for future research are also provided

Testimonial Injustice and Vulnerability: A Qualitative Analysis of Participation in the Court of Protection

This article explores participation in Court of Protection (COP) proceedings by people considered vulnerable. The paper is based on original data obtained from observing COP proceedings and reviewing COP case files. It is argued that the observed absence of the subject of proceedings is a form of testimonial injustice, that is, a failure to value a person in their capacity as a giver of knowledge. The issue of competence to give evidence is considered but it is argued that it is not the formal evidential rules that prohibit a vulnerable adult from giving evidence. Instead, it is the result of a persistent assumption that they are inherently vulnerable and therefore lack credibility as a knowledge giver. This assumption results in the voices of vulnerable adults being routinely absent from legal proceedings. It is argued that having a voice in the courtroom is essential and has a number of intrinsic and instrumental benefits. The paper concludes with a discussion about the implications of the research, including the current trend towards the increased use of special measures, and recommends a presumption in favour of the subject of COP proceedings giving evidence

Why do we need (another) special issue on gender and VET?

The Journal of Vocational Education and Training last had a special issue on gender and vocational education and training (VET) in 2006. In the intervening 8 years, the journal has published 264 research papers, of which just 10 - that is, less than 4% - addressed the issue of gender in any substantive way. This is something of a disappointment, as editors always hope that a special issue will provoke increased discussion and debate in the journal about its theme as well as providing a focused resource. Is the problem that, compared to the effects of global labour migration flows, constantly rising youth unemployment figures or emerging skills gaps in an aging society, gender issues have lost their relevance as just one category of social inequalities among many others? This can hardly be the case, since it is obviously a most thorough-going and persistent one. Despite over 30 years of gender studies, and numerous policy initiatives to address gender inequalities, gender segregation persists in VET as well as in the labour market. Women still earn less, hold the majority of part-time contracts, tend to be stereotyped into caring and personal service work, and are largely under-represented in leadership positions. Is the problem then that there is nothing new to be said about gender and VET? We do not agree that that is the case either: gender injustice remains a central issue in VET and the labour market; and as the social, political and economic landscape changes rapidly in today's world, it is inevitable that gender inequalities are produced and reproduced in new and different ways. So we felt the need to call once again for a collection of papers dedicated specifically to this topic, and one that would reflect this evolution
