Co-evaluation as a strategy to improve working group dynamics: an experience in Sport Sciences

The aim of this study was to analyze if the perceptions of students before and after carrying out the work, that is, their perception of different aspects of the functioning of the group, the working skills acquired as well as those they think that need to be improved, varied depending on whether the contribution of the different members of the group was being co-evaluated or not. 144 students of Physical Activity and Sport Sciences participated in this study. In order to analyze the students' perception of group work the adapted questionnaire by Bourne et al. (2001) was used. Results showed that groups which implemented co-evaluation assessed more negatively the experience in general than those which did not. However, co-evaluation groups perceived their competence to work as a team had improved to a greater extent than the groups without co-evaluation, evaluating more positively both the performance and the result of work and increasing their knowledge of the other team members. Using a co-evaluation system seems to generate both a better assessment of the running of the team and the result of its work.

The Sustainability Balanced Scorecard. Linking Sustainability Management to Business Strategy.

The Balanced Scorecard of Kaplan and Norton is a management tool that supports the successful implementation of corporate strategies. It has been discussed and considered widely in both practice and research. By linking operational and non-financial corporate activities with causal chains to the firm's long-term strategy, the Balanced Scorecard supports the alignment and management of all corporate activities according to their strategic relevance. The Balanced Scorecard makes it possible to take into account non-monetary strategic success factors that significantly impact the economic success of a business. The Balanced Scorecard is thus a promising starting-point to also incorporate environmental and social aspects into the main management system of a firm. Sustainability management with the Balanced Scorecard helps to overcome the shortcomings of conventional approaches to environmental and social management systems by integrating the three pillars of sustainability into a single and overarching strategic management tool. After a brief discussion of the different possible forms of a Sustainability Balanced Scorecard the article takes a closer look at the process and steps of formulating a Sustainability Balanced Scorecard for a business unit. Before doing so, the basic conventional approach of the Balanced Scorecard and its suitability for sustainability management will be outlined in brief.

Proteasome inhibitors: a therapeutic strategy for haematological malignancy

The proteasome is a multicatalytic enzyme complex responsible for the regulated degradation of intracellular proteins. In recent years, inhibition of proteasome function has emerged as a novel anti-cancer therapy. Proteasome inhibition is now established as an effective treatment for relapsed and refractory multiple myeloma and offers great promise for the treatment of other haematological malignancies, when used in combination with conventional therapeutic agents. Bortezomib is the first proteasome inhibitor to be used clinically and a second generation of proteasome inhibitors with differential pharmacological properties are currently in early clinical trials. This review summarises the development of proteasome inhibitors as therapeutic agents and describes how novel assays for measuring proteasome activity and inhibition may help to further delineate the mechanisms of action of different proteasome inhibitors. This will allow for the optimized use of proteasome inhibitors in combination therapies and provide the opportunity to design more potent and therapeutically efficacious proteasome inhibitors.

Insight into the key aspects of the regeneration process in the NOx storage reduction (NSR) reaction probed using fast transient kinetics coupled with isotopically labelled (NO)-N-15 over Pt and Rh-containing Ba/Al2O3 catalysts

For the first time, the coupling of fast transient kinetic switching and the use of an isotopically labelled reactant (15NO) has allowed detailed analysis of the evolution of all the products and reactants involved in the regeneration of a NOx storage reduction (NSR) material. Using realistic regeneration times (ca. 1 s) for Pt, Rh and Pt/Rh-containing Ba/Al2O3 catalysts we have revealed an unexpected double peak in the evolution of nitrogen. The first peak occurred immediately on switching from lean to rich conditions, while the second peak started at the point at which the gases switched from rich to lean. The first evolution of nitrogen occurs as a result of the fast reaction between H2 and/or CO and NO on reduced Rh and/or Pt sites. The second N2 peak which occurs upon removal of the rich phase can be explained by reaction of stored ammonia with stored NOx, gas phase NOx or O2. The ammonia can be formed either by hydrolysis of isocyanates or by direct reaction of NO and H2.

The study highlights the importance of the relative rates of regeneration and storage in determining the overall performance of the catalysts. The performance of the monometallic 1.1%Rh/Ba/Al2O3 catalyst at 250 and 350 °C was found to be dependent on the rate of NOx storage, since the rate of regeneration was sufficient to remove the NOx stored in the lean phase. In contrast, for the monometallic 1.6%Pt/Ba/Al2O3 catalyst at 250 °C, the rate of regeneration was the determining factor with the result that the amount of NOx stored on the catalyst deteriorated from cycle to cycle until the amount of NOx stored in the lean phase matched the NOx reduced in the rich phase. On the basis of the ratio of exposed metal surface atoms to total Ba content, the monometallic 1.6%Pt/Ba/Al2O3 catalyst outperformed the Rh-containing catalysts at 250 and 350 °C even when CO was used as a reductant.

Vision and reality: community involvement in Irish urban regeneration

This article examines the processes and outcomes of community involvement in six Irish urban regeneration case studies, three in Dublin and three in Belfast. The findings are part of a wider study using a Complex Adaptive Systems perspective to analyse public sector decision making. Key points included: (1) the community ‘vision’ of the regeneration as an emergent property, which converged towards the vision held by the implementing agencies in the four most successful programmes; and (2) the identification of three features that contribute to non-linear (unpredictable) behaviour: a history of community involvement; the availability of resources; and the intervention of key individuals at crisis points.

Integrating Ballymun? Flawed progress in Ireland's largest estate regeneration scheme

Urban regeneration in the Republic of Ireland takes place in the context of the rapid, ‘Celtic Tiger’ economic growth of the 1990s. The boom transformed Irish society and led to greater affluence for many people, along with continuing and arguably worsening inequality for those excluded from its opportunities. In particular, Ireland’s small social rented sector has become the focus of the country’s most concentrated poverty and social exclusion. The Ballymun regeneration programme in North Dublin aims to facilitate physical, social and economic change in order to integrate the area more closely with the
more affluent surrounding suburbs. This article reviews the issues involved in restructuring such a large area of social exclusion within a rapidly changing European capital city, using a framework that disaggregates the concept of integration into three elements: market, citizenship and reciprocity. With just over half the physical refurbishment complete, progress has been made but some fundamental issues remain. The article concludes that although substantial advancement has been made with physical regeneration, progress with wider economic and social integration has been uneven and in some cases flawed.
