This article argues against the merger folklore that maintains that a merger negatively affects well-being and work attitudes primarily through the threat of job insecurity. We hold that the workplace is not only a resource for fulfilling a person's financial needs, but that it is an important component of the self-concept in terms of identification with the organization, as explained by social identity theory. We unravel the key concepts of the social identity approach relevant to the analysis of mergers and review evidence from previous studies. Then, we present a study conducted during a merger to substantiate our ideas about the effects of post-merger organizational identification above and beyond the effects of perceived job insecurity. We recommend that managers should account for these psychological effects through the provision of continuity and specific types of communication. © 2006 British Academy of Management.

The Visually Evoked Subcortical Potential, a far-field signal, was originally defined to flash stimulation as a triphasic positive-negative-positive complex with mean latencies of P21 N26.2 P33.6 (Harding and Rubinstein 1980). Inconsistent with its subcortical source however, the signal was found to be tightly localised to the mastoid. This thesis re-examines the earlier protocols using flash stimulation and with auditory masking establishes by topographic studies that the VESP has a widespread scalp distribution, consistent with a far-field source of the signal, and is not a volume-conducted electroretinogram (ERG). Furthermore, mastoid localisation indicates auditory contamination from the click, on discharge of the photostimulator. The use of flash stimulation could not precisely identify the origin of the response. Possible sources of the VESP are the lateral geniculate body (LGB) and the superior colliculus. The LGB received 80% of the nerve fibres from the retina, and responds to high contrast achromatic stimulation in the form of drifting gratings of high spatial frequencies. At low spatial frequencies, it is more sensitive to colour. The superior colliculus is insensitive to colour and suppressed by contrast and responds to transitory rapid movements, and receives about 20% of the optic nerve fibres. A pattern VESP was obtained to black and white checks as a P23.5 N29.2 P34 complex in 93% of normal subjects at an optimal check size of 12'. It was also present as a P23.0 N28.29 P32.23 complex to red and green luminance balanced checks at 2o check size in 73% of subjects. These results were not volume-conducted pattern electroretinogram responses. These findings are consistent with the spatial frequency properties of the lateral geniculate body which is the considered source of the signal. With further work, the VESP may supplement electrodiagnosis of post-chiasmal lesions.

This paper draws upon four case studies to examine characteristics, entrepreneurial motivations and access to finance of black and minority ethnic (BME) graduates in the UK. We find that BME graduates starting a business are motivated by a desire to “do better”, and rely heavily on personal savings and family sources for start-up capital. In addition: • There is no conclusive evidence that suggests in this study that BME graduates entered entrepreneurship because of unemployment; with the exception of a few, all had jobs prior to entering self employment. • “Glass ceilings” were often cited by participants of the case studies as a kind of barrier, but there was reluctance to specify exactly what that meant. • Also, lack of satisfaction from working for others is considered to be a strong motivator for entering self-employment but other reasons, to be one’s own boss and the prospect of higher earnings, are also strong motivators. There is, therefore, a need for support agencies and universities to recognise the distinctive nature of BME graduate enterprise in order to provide effective solutions for different groups. This might include a) work experience, b) advice on an adequate capital structure at start up, c) adequate funding and training, and d) appropriate training for all graduates in basic business education.
