Abstract
Purpose
The purpose of this paper is to demonstrate how commercially‐off‐the‐shelf sensors and stimulators, such as infrared rangers and vibrators, can be retrofitted as a useful assistive technology in real and virtual environments.
Design/methodology/approach
The paper describes how a wearable range‐vibrotactile device is designed and tested in the real‐world setting, as well as thorough evaluations in a virtual environment for complicated navigation tasks and neuroscience studies.
Findings
In the real‐world setting, a person with normal vision who has to navigate their way around a room with their eyes closed will quickly rely on their arms and hands to explore the room. The authors’ device allows a person to “feel” their environment without touching it. Due to inherent difficulties in testing human subjects when navigating a real environment, a virtual environment affords us an opportunity to scientifically and extensively test the prototype before deploying the device in the real‐world.
Research limitations/implications
This project serves as a starting‐point for further research in benchmarking assistive technology for the visually impaired and to eventually develop a man‐machine sensorimotor model that will improve current state‐of‐the‐art technology, as well as a better understanding of neural coding in the human brain.
Social implications
Based on 2012 World Health Organization, there are 39 million blind people. This project will have a direct impact on this community.
Originality/value
The paper demonstrates a low cost design of assistive technology that has been tested and evaluated in real and virtual environments, as well as integration of sensor designs and neuroscience.

Abstract
We provide a comprehensive synthesis and extension of the real option (RO) literature on joint ventures (JVs), contributing in three main areas. First, we examine major alternative theoretical perspectives on JVs – learning, bargaining, transaction cost and agency theory – to elaborate how they complement or contradict RO predictions. Second, we compare arguments and variables used to explain different JV stages – initial RO explicitness and equity shares, JV stability, and performance consequences – and highlight research opportunities. Third, we discuss and extend research about behavioral aspects of making RO (JV) investments. Overall, we offer new predictions and suggestions for a better integration within the RO literature, and between RO and related literatures on JVs.

Abstract
Presents over sixty abstracts summarising the 1999 Employment Research Unit annual conference held at the University of Cardiff. Explores the multiple impacts of globalization on work and employment in contemporary organizations. Covers the human resource management implications of organizational responses to globalization. Examines the theoretical, methodological, empirical and comparative issues pertaining to competitiveness and the management of human resources, the impact of organisational strategies and international production on the workplace, the organization of labour markets, human resource development, cultural change in organisations, trade union responses, and trans‐national corporations. Cites many case studies showing how globalization has brought a lot of opportunities together with much change both to the employee and the employer. Considers the threats to existing cultures, structures and systems.

Abstract
In this article we compare the performance of the traditional CAPM with the multi factor model of Fama and French (1996) for equities listed in the Shanghai Stock Exchange. We also investigate the explanatory power of idiosyncratic volatility and respond to the claim that multi factor model findings can be explained by the turn of the year effect. Our results show that firm size, book to market equity and idiosyncratic volatility are priced risk factors in addition to the theoretically well specified market factor. As far as the turn of the year effect is concerned we reject the claim that the findings are driven by seasonal factors.

Abstract
Discusses attempts by the government’s political opposition (in the UK) to break the consensus on welfare and considers whether the recent change in political power has materially altered the direction of policy relating to care in the community and the role of social workers. Charts the development of the British welfare state from its conception in 1945 through to the present day, focussing on recent reforms in community care provisions and the role of social workers; details how the profession has been undermined by a series of events and profiles the former government’s response. Identifies that the welfare role of social workers has diminished, and been replaced with a social control function. Concludes that, despite the legacy inherited from the previous government, a shift in the political approach to social services and community care provision is discernible.

Abstract
This article deconstructs the hagiography surrounding British mental health policy and provides a critical analysis of the ‘New Labour’ Government reforms of the Mental Health Act 1983 grounded in Foucauldian insights. Smart (1985) suggests that a Foucauldian perspective deconstructs “common sense assumptions” that lie at the heart of policies formulated by the State. A cogent discussion grounded in Foucault’s work can illustrate how surveillance and discourses of power impact on the positioning of service users as objects of control, domination and subordination.
