Evaluating EU regional policy

This article presents a challenge to the ways in which EU regional policy has been evaluated in the past. Given the complexity of the 'policy framework' and its objectives, it is argued that existing evaluation methodologies are not only inappropriate but create a real risk of misleading policy-makers in their search for identifying which programmes and initiatives are the most effective in tackling the scale of regional disparity that exists across the European Union. For example, the search for an 'average effect' of intervention, whether in terms of jobs created or GVA generated, does not adequately recognise the context within which policy operates. The article argues that only by attempting to adopt a realist evaluation framework can the discourse on effective regional policy be advanced. Examples are provided from a body of work on the evaluation of business support interventions in the UK as well as a broader study of the way in which regulations impacts upon firm performance and growth. This methodological approach provides an opportunity for the evaluator to identify the causal mechanisms which connect the range of policy interventions and their outcomes. In brief, it has greater potential to inform the policy-maker as to what works and, more importantly, in what contexts.

Distinct contrast response functions in striate and extra-striate regions of visual cortex revealed with magnetoencephalography (MEG)

Objective: To spatially and temporally characterise the cortical contrast response function to pattern onset stimuli in humans. Methods: Magnetoencephalography (MEG) was used to investigate the human cortical contrast response function to pattern onset stimuli with high temporal and spatial resolution. A beamformer source reconstruction approach was used to spatially localise and identify the time courses of activity at various visual cortical loci. Results: Consistent with the findings of previous studies, MEG beamformer analysis revealed two simultaneous generators of the pattern onset evoked response. These generators arose from anatomically discrete locations in striate and extra-striate visual cortex. Furthermore, these loci demonstrated notably distinct contrast response functions, with striate cortex increasing approximately linearly with contrast, whilst extra-striate visual cortex followed a saturating function. Conclusions: The generators that underlie the pattern onset visual evoked response arise from two distinct regions in striate and extra-striate visual cortex. Significance: The spatially, temporally and functionally distinct mechanisms of contrast processing within the visual cortex may account for the disparate results observed across earlier studies and assist in elucidating causal mechanisms of aberrant contrast processing in neurological disorders. © 2005 International Federation of Clinical Neurophysiology.

ICT adoption and ebusiness development:Understanding ICT adoption amongst ethnic minority businesses

This paper builds upon a series of studies that have identified the comparatively low uptake of ICT amongst EMBs (Ram and Smallbone, 1999; Foley and Ram 2002; Allinson et al., 2004). Existing studies have only tentatively considered the causal factors for this lower adoption rate in comparison to non-EMBs. Within the context of a pilot study, aiming to understand ICT adoption amongst EMBs, an action research approach is adopted as a means of influencing, evaluating and underpinning ICT adoption (Beckinsale and Ram, 2006). The approach is methodologically distinctive in its utilization of action research with a critical realist approach as a means of policy evaluation; this is conducive to 'policy learning', and the understanding of causal mechanisms in the EMBs. Actors involved in the implementation were interviewed, as well as the business owners themselves. Another distinguishing feature is the application of Yap et al.'s (1992) schema to identify causal mechanisms, to examine actions and experiences and to understand the impact on the EMBs studied. The findings highlight the complex interaction and relationships of internal and external factors in shaping approaches to ICT implementation. Factors such as size, strategy and business age are germane but so too, albeit to a lesser degree, are cultural influences such as involvement in co-ethnic networks. Significantly, changes to particular causal mechanisms such as business support altered adoption and implementation of ICT. Distinct issues for Chinese and Asian-owned business and potentially more broadly EMBs are identified providing a framework for other EMBs. © The Author(s) 2010.

Person-organization fit and incentives:a causal test

We investigate the effects of organizational culture and personal values on performance under individual and team contest incentives. We develop a model of regard for others and in-group favoritism that predicts interaction effects between organizational values and personal values in contest games. These predictions are tested in a computerized lab experiment with exogenous control of both organizational values and incentives. In line with our theoretical model we find that prosocial (proself) orientated subjects exert more (less) effort in team contests in the primed prosocial organizational values condition, relative to the neutrally primed baseline condition. Further, when the prosocial organizational values are combined with individual contest incentives, prosocial subjects no longer outperform their proself counterparts. These findings provide a first, affirmative, causal test of person-organization fit theory. They also suggest the importance of a 'triple-fit' between personal preferences, organizational values and incentive mechanisms for prosocially orientated individuals.

The effects of servant leadership on follower performance and well-being:underlying mechanisms, boundary conditions, and the role of training

Based on a review of the servant leadership, well-being, and performance literatures, the first study develops a research model that examines how and under which conditions servant leadership is related to follower performance and well-being alike. Data was collected from 33 leaders and 86 of their followers working in six organizations. Multilevel moderated mediation analyses revealed that servant leadership was indeed related to eudaimonic well-being and lead-er-rated performance via followers’ positive psychological capital, but that the strength and di-rection of the examined relationships depended on organizational policies and practices promot-ing employee health, and in the case of follower performance on a developmental team climate, shedding light on the importance of the context in which servant leadership takes place. In addi-tion, two more research questions resulted from a review of the training literature, namely how and under which conditions servant leadership can be trained, and whether follower performance and well-being follow from servant leadership enhanced by training. We subsequently designed a servant leadership training and conducted a longitudinal field experiment to examine our sec-ond research question. Analyses were based on data from 38 leaders randomly assigned to a training or control condition, and 91 of their followers in 36 teams. Hierarchical linear modeling results showed that the training, which addressed the knowledge of, attitudes towards, and ability to apply servant leadership, positively affected leader and follower perceptions of servant leader-ship, but in the latter case only when leaders strongly identified with their team. These findings provide causal evidence as to how and when servant leadership can be effectively developed. Fi-nally, the research model of Study 1 was replicated in a third study based on 58 followers in 32 teams drawn from the same population used for Study 2, confirming that follower eudaimonic well-being and leader-rated performance follow from developing servant leadership via increases in psychological capital, and thus establishing the directionality of the examined relationships.
