Organisations face an increasingly competitive and uncertain global environment, after recent experience of unparalleled technological
advances and political shifts. Increased dependence on Information Technology (IT) will require appropriate human resource
strategies, to develop individuals who will be capable of operating successfully within new organisational structures, with
reduced management layers and a requirement for teamworking.
This paper presents a university-industry based partnership, revolving around a final year Group Consultancy project, in which
undergraduate students work with an external client on a live problem. The project involves the use ofaction research methodology, where academic ideas are applied in the ‘real’ world of business. This is described in the context of group
projects, which examine thelegacy system problems faced by three multi-national organisations.

Despite the acknowledged contribution of Small and Medium Enterprises (SMEs) to the food industry there is increasing evidence that Hazard Analysis Critical Control Point (HACCP) implementation is limited in this sector, with the burden of implementation perceived as potentially insurmountable. Using an action research methodology, this in-depth, government funded research project took the form of a two stage, 18 month investigation into methods of reducing burdens of HACCP on SMEs. Stage one indicted that SMEs see HACCP as a difficult, complex set of activities requiring great amounts of time effort and with few, if any, perceived benefits. In stage two, however, with the help of research tools developed, a number of SMEs completed HACCP and many made good progress on a tight timescale. This research thus concludes that SMEs can achieve HACCP if they are provided with sufficient guidance and support in a context of general consensus of HACCP terminology and requirements. Recommendations are made, many of which have been subsequently adopted by the UK Food Standards Agency. 相似文献

AbstractThis paper puts forward a framework that assists managers to prepare action plans using attributes of Kano’s Model and to order them by utilizing multi-criteria decision analysis. The framework was applied in a company, a division of which provides a vehicle tracking service. Data were collected on its top 10 customers, all of which are large companies. The results show the proposed framework contributes to the decision-making process, since it enables the order of the actions to be rationalized, and takes the multiple criteria relevant to the company into consideration. Moreover, the fact that it is difficult to rank the 20 actions needed without the approach proposed in this article reinforces the need for and the importance of the framework and other complementary contributions in order to overcome this difficulty. 相似文献

Collective action and community ecology theories frame this study of longitudinal interorganizational networks in Croatia during the country's political transition. As time progresses toward political stability, grass-roots organizing activities shift through participation in new networks. Although engaged cross-sector communication was important in early stages of the transformation, homophilous partnering emerged as the system stabilized. System stability left room for organizations to exit the collective action network but with costs associated with centralized organizing. Over time, organizations embodied roles as ideological leaders, collective action network leaders, and within-sector network partners. We offer a unique contribution to community ecology and collective action theories with a communication-centered framework that emphasizes the nature of communication in interorganizational networks over a 4-year period. 相似文献

Although multiple methods have been proposed for human action recognition, the existing multi-view approaches cannot well discover meaningful relationship among multiple action categories from different views. To handle this problem, this paper proposes an multi-view learning approach for multi-view action recognition. First, the proposed method leverages the popular visual representation method, bag-of-visual-words (BoVW)/fisher vector (FV), to represent individual videos in each view. Second, the sparse coding algorithm is utilized to transfer the low-level features of various views into the discriminative and high-level semantics space. Third, we employ the multi-task learning (MTL) approach for joint action modeling and discovery of latent relationship among different action categories. The extensive experimental results on M2I and IXMAS datasets have demonstrated the effectiveness of our proposed approach. Moreover, the experiments further demonstrate that the discovered latent relationship can benefit multi-view model learning to augment the performance of action recognition. 相似文献
