Designing transition paths for the diffusion of sustainable system innovations. A new potential role for design in transition management?

Copyright @ 2008 Umberto AllemandiIt is a shared opinion that the transition towards sustainability will be a continuous and articulated learning process, which will require radical changes on multiple levels (social, cultural, institutional and technological). It is also shared that, given the nature and the dimension of those changes, a system discontinuity is needed, and that therefore it is necessary to act on a system innovation level. The challenge now is to understand how it is possible to facilitate and support the introduction and diffusion of such innovations. Bringing together insights from both Design for sustainability and Transition management literatures, the paper puts forward a model, called Transition model of evolutionary co-design for sustainable (product-service) system innovations, aimed at facilitating and speed-up the process of designing, experimentation, niche introduction and branching of sustainable such innovations

The influence of work placement on the academic achievement of undergraduate design students

The aim of this paper is to investigate the contribution of work placement in enhancing the academic performance of undergraduate design students. A statistical analysis was carried out on a population sample which comprised design students who had graduated at Brunel University London in four different academic years. All the required (anonymous) data were obtained from the university electronic records system. The dataset comprises a total of 411 students, of which 323 were placement students and 88 non-placement students. Students were also classified as higher achievers (students whose second year average mark was 60% or above) and lower achievers. The results seem to suggest that for both higher and lower achievers the placement experience enables students to achieve on average a greater final year mark and a greater improvement from the second to the final year. The study also established that these grade gains were of a similar magnitude irrespective of the students overall academic standing. Finally, the results of this study seem to suggest that the work placement experience give students a particular advantage in the final year project and in the modules characterized by design-focused assessment components

A Multivariate Surface-Based Analysis of the Putamen in Premature Newborns: Regional Differences within the Ventral Striatum

Many children born preterm exhibit frontal executive dysfunction, behavioral problems including attentional deficit/hyperactivity disorder and attention related learning disabilities. Anomalies in regional specificity of cortico-striato-thalamo-cortical circuits may underlie deficits in these disorders. Nonspecific volumetric deficits of striatal structures have been documented in these subjects, but little is known about surface deformation in these structures. For the first time, here we found regional surface morphological differences in the preterm neonatal ventral striatum. We performed regional group comparisons of the surface anatomy of the striatum (putamen and globus pallidus) between 17 preterm and 19 term-born neonates at term-equivalent age. We reconstructed striatal surfaces from manually segmented brain magnetic resonance images and analyzed them using our in-house conformal mapping program. All surfaces were registered to a template with a new surface fluid registration method. Vertex-based statistical comparisons between the two groups were performed via four methods: univariate and multivariate tensor-based morphometry, the commonly used medial axis distance, and a combination of the last two statistics. We found statistically significant differences in regional morphology between the two groups that are consistent across statistics, but more extensive for multivariate measures. Differences were localized to the ventral aspect of the striatum. In particular, we found abnormalities in the preterm anterior/inferior putamen, which is interconnected with the medial orbital/prefrontal cortex and the midline thalamic nuclei including the medial dorsal nucleus and pulvinar. These findings support the hypothesis that the ventral striatum is vulnerable, within the cortico-stiato-thalamo-cortical neural circuitry, which may underlie the risk for long-term development of frontal executive dysfunction, attention deficit hyperactivity disorder and attention-related learning disabilities in preterm neonates. © 2013 Shi et al

An African-European network of design universities fostering the goal of sustainable energy for all

This paper presents the intermediate results of the Learning Network on Sustainable Energy Systems (LeNSes) an African-European multi-polar network for curriculum development on Design for Sustainability (DfS) focused on Distributed Renewable Energy (DRE) and Sustainable Product-Service Systems (S.PSS). The paper discusses the convergence between the S.PSS and DRE models as promising approaches to provide sustainable energy solutions for all by increasing its access and improving efficiency in use. Currently, the project partners are collaboratively developing new curricula focused on these combined approaches. The paper examines the S.PSS and DRE models and how they can be used to develop and implement sustainable energy solutions for all within the African context. The research hypothesis is that S.PSS could be applied to DRE to offer a range of benefits such as: economic, environmental and socio-ethical. The paper describes some of the project activities that includes: development of a new modular and adaptable package of learning resources focused on DRE and S.PSS for the design discipline; implementation of pilot courses at African Higher Educational Institutions (HEIs) targeted at undergraduate and graduate students, practitioners and companies; and development of an open web platform for distributed production and transfer of knowledge and know-how in this area. The innovation of the project described in the paper is twofold, firstly by developing unique curricula based on design for sustainability focused on S.PSS and DRE applied to the African contexts, and secondly by delivering it through an open platform for free and in copy-left. This will equip design students in African universities with a broad knowledge base, as well as effective methods and tools with which to play an active role in the development and diffusion of sustainable energy systems

Altered structural and functional connectivity in late preterm preadolescence: An anatomic seed-based study of resting state networks related to the posteromedial and lateral parietal cortex

Objective: Late preterm birth confers increased risk of developmental delay, academic difficulties and social deficits. The late third trimester may represent a critical period of development of neural networks including the default mode network (DMN), which is essential to normal cognition. Our objective is to identify functional and structural connectivity differences in the posteromedial cortex related to late preterm birth. Methods: Thirty-eight preadolescents (ages 9-13; 19 born in the late preterm period (≥32 weeks gestational age) and 19 at term) without access to advanced neonatal care were recruited from a low socioeconomic status community in Brazil. Participants underwent neurocognitive testing, 3-dimensional T1-weighted imaging, diffusion-weighted imaging and resting state functional MRI (RS-fMRI). Seed-based probabilistic diffusion tractography and RS-fMRI analyses were performed using unilateral seeds within the posterior DMN (posterior cingulate cortex, precuneus) and lateral parietal DMN (superior marginal and angular gyri). Results: Late preterm children demonstrated increased functional connectivity within the posterior default mode networks and increased anti-correlation with the central-executive network when seeded from the posteromedial cortex (PMC). Key differences were demonstrated between PMC components with increased anti-correlation with the salience network seen only with posterior cingulate cortex seeding but not with precuneus seeding. Probabilistic tractography showed increased streamlines within the right inferior longitudinal fasciculus and inferior fronto-occipital fasciculus within late preterm children while decreased intrahemispheric streamlines were also observed. No significant differences in neurocognitive testing were demonstrated between groups. Conclusion: Late preterm preadolescence is associated with altered functional connectivity from the PMC and lateral parietal cortex to known distributed functional cortical networks despite no significant executive neurocognitive differences. Selective increased structural connectivity was observed in the setting of decreased posterior interhemispheric connections. Future work is needed to determine if these findings represent a compensatory adaptation employing alternate neural circuitry or could reflect subtle pathology resulting in emotional processing deficits not seen with neurocognitive testing.

Eulerian Multi-Fluid Model for Polydisperse Flows

This work restricts the term multiphase only to disperse flows, where one of the phases is present in the form of particles, droplets or bubbles, which are suspended within the continuous phase. The dispersed elements can vary in size. The proposed method uses the classes method in the Euler-Euler framework to handle the flow's polydisperse nature. With this approach, every droplet/bubble/particle class is treated like a different phase in the calculation, i.e. every size class has its continuity and momentum equation. However, the pressure is shared among all phases. The derived model is tested for various polydisperse flows, which display the developed model's capability to predict such complex dynamic behaviour. These test cases include complex bubbly flows and dense spray (where droplet sizes vary significantly)

L’attività di sorveglianza audiologica pediatrica in Italia: raccomandazioni preliminari

Sulla base dei risultati dei programmi di screening uditivo neonatale attivi in diverse regioni italiane, si è resa necessaria una riflessione riguardo all’identificazione delle ipoacusie sfuggite al programma di screening neonatale, delle ipoacusie progressive o insorte dopo la nascita. Nell’ambito del progetto del Ministero della Salute CCM 2013 “Programma regionale di identificazione, intervento e presa in carico precoci per la prevenzione dei disturbi comunicativi nei bambini con deficit uditivo” un gruppo di esperti ha identificato tre principali raccomandazioni utili per ottimizzare l’attività di sorveglianza audiologica pediatrica nell’ambito del Servizio Sanitari Nazionale. Il pediatra di famiglia è riconosciuto come la figura chiave per il monitoraggio delle capacità uditive e dello sviluppo del bambino

Integrating S.PSS and DE

The combination of Sustainable Product-Service Systems (S.PSS) and Distributed Economies (DE) has been considered as a promising mode of developing sustainability through regional resilience and by empowering a shift to a more localized economic model. This chapter examines case studies from around the world that use combinations of S.PSS and DE to varying degrees and in different industry sectors to analyse the opportunities that it presents. The chapter then goes on to provide a framework for categorizing various models of S.PSS and DE combinations and ends with an analysis of the barriers to implement such models
