The effect of local corticosteroid injection on F-wave conduction velocity and sympathetic skin response in carpal tunnel syndrome

The aim of this study was to evaluate the efficacy of steroid injection for the treatment of the carpal tunnel syndrome (CTS), with F-wave parameters and sympathetic skin response (SSR). Seventeen hands of 10 women patients were treated with local steroid injection with 2-month follow-up. All patients underwent single injection into the carpal tunnel. Response to injection was measured nerve conduction studies (NCSs), median nerve F waves, and SSR before and after treatment. To determine the normal values, 42 hands of 21 healthy women were also studied. There was a significant improvement of sensory and motor nerve conduction values when compared to baseline values (P < 0.01). At the end of follow-up period, the median sensory distal latency and the sensory latency differences between the median and the ulnar nerve were improved 35 and 65%, respectively. The maximum, mean F-wave amplitudes and chronodispersion showed a slight improvement with respect to baseline values and controls, but statistical significance was not achieved after treatment. Although no statistically significant improvements were observed in SSR parameters, slightly decreased amplitudes and increased habituation of SSR were noted at the end of the treatment. The present study shows that the local steroid injection results in improvement in NCSs values, but the F-wave parameters were not effectual in short-term outcome of CTS treatment. These findings suggest that the sensory latency differences between the median and the ulnar wrist-to-digit 4 are better parameters in the median nerve recovery after treatment than the median sensory distal latency. Furthermore, the SSR does not seem to be a sensitive method in follow-up of CTS treatment

Meta Modeling for Business Process Improvement

Conducting business process improvement (BPI) initiatives is a topic of high priority for today’s companies. However, performing BPI projects has become challenging. This is due to rapidly changing customer requirements and an increase of inter-organizational business processes, which need to be considered from an end-to-end perspective. In addition, traditional BPI approaches are more and more perceived as overly complex and too resource-consuming in practice. Against this background, the paper proposes a BPI roadmap, which is an approach for systematically performing BPI projects and serves practitioners’ needs for manageable BPI methods. Based on this BPI roadmap, a domain-specific conceptual modeling method (DSMM) has been developed. The DSMM supports the efficient documentation and communication of the results that emerge during the application of the roadmap. Thus, conceptual modeling acts as a means for purposefully codifying the outcomes of a BPI project. Furthermore, a corresponding software prototype has been implemented using a meta modeling platform to assess the technical feasibility of the approach. Finally, the usability of the prototype has been empirically evaluated

Becoming Sustainable in Our Own Way: Sustainability at the Flagship Massachusetts Public University

This presentation was delivered at the 2016 World Symposium on Sustainable Development at Universities . It outlines a case study of the comprehensive sustainability efforts undertaken by the University of Massachusetts Amherst and evaluates its progress by applying Kotter’s 8-step approach to change management to multiple phases of the campus development efforts. Emphasis is placed on efforts to integrate sustainability goals with campus master planning, facility plans, green building policies, governance and educational and operations teaching and research initiatives. The presentation also outlines concrete steps for comprehensive physical planning that universities may consider as they integrate change management practices for sustainable development into their campus’ vision of sustainability. Publication of a paper of the same title will be published by Springer in Handbook of Theory and Practice of Sustainable Development in Higher Education - Volume 3, 2017

Organization design and firm heterogeneity: towards an integrated research agenda for strategy

We argue that organization design needs to play a more active role in the explanation of differential performance and outline a set of ideas for achieving this both in theoretical and empirical research. Firms are heterogeneous in terms of 1) how well they do things, capturing persistent productivity differences, and 2) how they do things — and both reflect firms’ organization design choices. Both types of heterogeneity can be persistent, and are interdependent, although they have typically been studied separately. We propose a simple formal framework — the “aggregation function framework” — that aligns organization design thinking with the emphasis on performance heterogeneity among firms that is characteristic of the strategy field. Our framework allows for a more precise identification of how exactly organization design may contribute to persistent performance differences, and therefore what exactly are the assumptions that strategy and organization design scholars need to be attentive to

Leadership and Change: The Case for Greater Ethical Clarity

This article addresses the relationship between the ethics underpinning leadership and change. It examines the developments in leadership and change over the last three decades and their ethical implications. It adopts a consequentialist perspective on ethics and uses this to explore different approaches to leadership and change. In particular, the article focuses on individual (egoistic) consequentialism and utilitarian consequentialism. The article argues that all leadership styles and all approaches to change are rooted in a set of values, some of which are more likely to lead to ethical outcomes than others. It also argues that all stakeholders in an organisation have a role to play in ensuring ethical outcomes. It concludes that in order to achieve sustainable and beneficial change, those who promote and adopt particular approaches to leadership and change must provide greater ethical clarity about the approaches they are championing
