Total dietary antioxidant capacity and longitudinal trajectories of body composition

Although there is some evidence that total dietary antioxidant capacity (TDAC) is inversely associated with the presence of obesity, no longitudinal studies have been performed investigating the effect of TDAC on comprehensive measures of body composition over time. In this study, we included 4595 middle-aged and elderly participants from the Rotterdam Study, a population-based cohort. We estimated TDAC among these individuals by calculating a ferric reducing ability of plasma (FRAP) score based on data from food-frequency questionnaires. Body composition was assessed by means of dual X-ray absorptiometry at baseline and every subsequent 3-5 years. From these data, we calculated fat mass index (FMI), fat-free mass index (FFMI), android-to-gynoid fat ratio (AGR), body fat percentage (BF%) and body mass index (BMI). We also assessed hand grip strength at two time points and prevalence of sarcopenia at one time point in a subset of participants. Data were analyzed using linear mixed models or multinomial logistic regression models with multivariable adjustment. We found that higher FRAP score was associated with higher FFMI (0.091 kg/m2 per standard deviation (SD) higher FRAP score, 95% CI 0.031; 0.150), lower AGR (-0.028, 95% CI -0.053; -0.003), higher BMI (0.115, 95% CI 0.020; 0.209) and lower BF% (-0.223, 95% CI -0.383; -0.064) across follow-up after multivariable adjustment. FRAP score was not associated with hand grip strength or sarcopenia. Additional adjustment for adherence to dietary guidelines and exclusion of individuals with comorbid disease at baseline did not change our results. In conclusion, dietary intake of antioxidants may positively affect the amount of lean mass and overall body composition among the middle-aged and elderly.

Determining the Required Capacity of Business Information Management

From the article: Many organizations are striving for a structural and professional approach toward business information management (BIM). With help of BiSL they can shape the BIM responsibilities and processes, but they struggle with the required capacity for the BIM activities necessary for their particular situation. Therefore, research was started to develop an instrument to determine the required capacity of the BIM activities in an organization. In this paper the construction of the instrument will be described. A limited set of factors may be of importance to identify the required capacity of BIM activities that is needed: complexity of business processes, complexity of IS/IT, dynamics of the organization and its environment and the size of the organization are examples of relevant factors. However, factors that appear relevant may prove useless in practice due to the fact that organizations have no data on these indicators available. Furthermore, the relationships between the present and desired quality of information and information services are part of the instrument. The instrument was tested in practice to determine the usefulness. The results show that the instrument has the potential to determine the required capacity of BIM.

From Pilot Projects to Transformative Infrastructures, Exploring Market Receptivity for Permeable Pavement in The Netherlands

Climate change and changing land use challenge the livability and flood safety of Dutch cities. One option cities have to become more climate-proof is to increase infiltration of stormwater into soil through permeable pavement and thus reduce discharge of stormwater into sewer systems. To analyze the market receptivity for permeable pavements in the Netherlands, this article focuses on the perception of end-users towards key transition factors in the infrastructure transformation processes. Market receptivity was studied on two levels: (1) on the system level, by analyzing 20 key factors in the Dutch urban water sector that enable wider application of permeable pavements; and (2) on the technology level, by analyzing 12 key factors that explain why decision makers select permeable pavements or not. Results show that trust between cooperating partners was perceived as the system level key factor that needs to be improved most to facilitate the wider uptake of permeable pavements. Additionally, the association of end-users with permeable pavement, particularly their willingness to apply these technologies and their understanding of what kinds of benefits these technologies could bring, was regarded the most important receptivity attribute. On the technology level, the reliability of permeable pavement was regarded as the most important end-user consideration for selecting this technology.

Adapting a capacity-development-in-higher-education project

In November 2019, scholars and practitioners from ten higher education institutions celebrated the launch of the iKudu project. This project, co-funded by Erasmus [1], focuses on capacity development for curriculum transformation through internationalisation and development of Collaborative Online International Learning (COIL) virtual exchange. Detailed plans for 2020 were discussed including a series of site visits and face-to-face training. However, the realities of the COVID-19 pandemic disrupted the plans in ways that could not have been foreseen and new ways of thinking and doing came to the fore. Writing from an insider perspective as project partners, in this paper we draw from appreciative inquiry, using a metaphor of a mosaic as our identity, to first provide the background on the iKudu project before sharing the impact of the pandemic on the project’s adapted approach. We then discuss how alongside the focus of iKudu in the delivery of an internationalised and transformed curriculum using COIL, we have, by our very approach as project partners, adopted the principles of COIL exchange. A positive impact of the pandemic was that COIL offered a consciousness raising activity, which we suggest could be used more broadly in order to help academics think about international research practice partnerships, and, as in our situation, how internationalised and decolonised curriculum practices might be approached. 1.

“Recovering” the political

In many European cities, urban experimentation is increasingly preferred as a method for testing and disseminating innovations that might ignite a transformation toward more sustainable cities. By both academics and practitioners, these experiments tend to be approached as relatively neutral initiatives through which plural urban stakeholders willfully collaborate, while their success is seen as above all dependent on effective management. For this reason, the political nature of urban experiments, in the sense that they entangle different and often contending stakeholders in their innovation processes, remains relatively unarticulated in both practice and the academic literature. Building on the urban experimentation literature and political theory, this conceptual paper argues that the depoliticization of experimental initiatives is especially problematic for unleashing their transformative potential, which requires revealing the existing power-relations and biases keeping the status-quo in place and negotiability of radical alternatives. From this perspective, the paper sketches out four ideal-typical trajectories for experiments as related to their (de)politicization; optimization, blind leap, antagonistic conflict and transformation. Bringing insights from political theory to bear on the urban experimentation literature, we proceed to hypothesize the implications of our ideal-types for urban experiments’ transformative capacities. The paper closes by presenting a future research and policy agenda.
