Te covered Si(001): a variable surface reconstruction

At a given temperature, clean and adatom covered silicon surfaces usually exhibit well-defined reconstruction patterns. Our finite temperature ab-initio molecular dynamics calculations show that the tellurium covered Si(001) surface is an exception. Soft longitudinal modes of surface phonons due to the strongly anharmonic potential of the bridged tellurium atoms prevent the reconstruction structure from attaining any permanent, two dimensional periodic geometry. This explains why experiments attempting to find a definite model for the reconstruction have reached conflicting conclusions.Comment: 4 pages, 3 gif figure

Dissonant entanglements and creative redistributions

This study aims to better understand how international cultural funding shapes opportunities for organizations to grow as generators of creativity able to provide transformative experiences for local audiences. It analyzes the experiences of four cases located in the Middle East and North Africa region, namely L’Atelier de l’Observatoire (Morocco), Clown Me In (Lebanon), Bantmag (Turkey), and Volunteer Palestine (West Bank). Although the Prince Claus Fund, Hivos, and European Cultural Foundation (ECF) have sought alternatives to the neoliberal instrumentalization of their funding measured according to the rubrics of impact, our research shows that organizations still struggle with the need to appeal to international funding bodies while also focusing on their work as embedded in local conditions.Global Challenges (FSW

Teaching open and reproducible scholarship: a critical review of the evidence base for current pedagogical methods and their outcomes.

YesIn recent years, the scientific community has called for improvements in the credibility, robustness and reproducibility of research, characterized by increased interest and promotion of open and transparent research practices. While progress has been positive, there is a lack of consideration about how this approach can be embedded into undergraduate and postgraduate research training. Specifically, a critical overview of the literature which investigates how integrating open and reproducible science may influence student outcomes is needed. In this paper, we provide the first critical review of literature surrounding the integration of open and reproducible scholarship into teaching and learning and its associated outcomes in students. Our review highlighted how embedding open and reproducible scholarship appears to be associated with (i) students' scientific literacies (i.e. students' understanding of open research, consumption of science and the development of transferable skills); (ii) student engagement (i.e. motivation and engagement with learning, collaboration and engagement in open research) and (iii) students' attitudes towards science (i.e. trust in science and confidence in research findings). However, our review also identified a need for more robust and rigorous methods within pedagogical research, including more interventional and experimental evaluations of teaching practice. We discuss implications for teaching and learning scholarship.UKRI/ESRC rapid call grant, ealth Research Board Applying Researchinto Policy and Practice Fellowship, John Templeton Foundation (grant ID: 62631), Northern Ireland Department for the Economy Research Studentshi

Advances in organ preserving strategies in rectal cancer patients

Treatment of rectal cancer patients has been subjected to change over the past thirty years. Total mesorectal excision is considered the cornerstone of rectal cancer treatment, but is also associated with significant morbidity resulting in an impaired quality of life. The addition of neoadjuvant chemoradiotherapy to surgery has shown to improve survival and local control and may lead to a partial or even complete response (CR). This raises questions regarding the necessity for subsequent radical surgery. After careful patient selection local excision and wait-and-see approaches are explored, aiming to improve quality of life without compromising oncological outcome. A multimodality diagnostic approach for optimal staging is crucial in determining the appropriate neoadjuvant treatment regimen. Adequate endoscopic restaging of rectal tumours after multimodality treatment will aid in selecting patients who are eligible for an organ preserving approach. The role and accuracy of imaging in the detection of the primary tumour, residual rectal cancer or local recurrence seems vital. Alternative neoadjuvant regimens are currently explored to increase the rate of clinical CRs, which may support organ preserving approaches. This review aims to generate insight into the advances in diagnostics and treatment modalities in all stages of rectal cancer and will highlight future studies that may support further implementation of organ preservation treatment in rectal cancer

Children of non-Western origin with end-stage renal disease in the Netherlands, Belgium and a part of Germany have impaired health-related quality of life compared with Western children

Item does not contain fulltextBACKGROUND: Many children with end-stage renal disease (ESRD) living in Western Europe are of non-Western European origin. They have unfavourable somatic outcomes compared with ESRD children of Western origin. In this study, we compared the Health-related Quality of Life (HRQoL) of both groups. METHODS: All children (5-18 years) with ESRD included in the RICH-Q project (Renal Insufficiency therapy in Children-Quality assessment and improvement) or their parents were asked to complete the generic version of the Paediatric Quality-of-Life Inventory 4.0 (PedsQL). RICH-Q comprises the Netherlands, Belgium and a part of Germany. Children were considered to be of non-Western origin if they or at least one parent was born outside Western-European countries. Impaired HRQoL for children with ESRD of Western or non-Western origin was defined as a PedsQL score less than fifth percentile for healthy Dutch children of Western or non-Western origin, respectively. RESULTS: Of the 259 eligible children, 230 agreed to participate. One hundred and seventy-four children responded (response rate 67%) and 55 (32%) were of non-Western origin. Overall, 31 (56%) of the ESRD children of non-Western origin, and 58 (49%) of Western origin had an impaired total HRQoL score. Total HRQoL scores of children with ESRD of Western origin and non-Western origin were comparable, but scores on emotional functioning and school functioning were lower in non-Western origin (P=0.004 and 0.01, respectively). The adjusted odds ratios (95% confidence interval) for ESRD children of non-Western origin to have impaired emotional functioning and school functioning, compared with Western origin, were 3.3(1.5-7.1) and 2.2(1.1-4.2), respectively. CONCLUSION: Children with ESRD of non-Western origin in three Western countries were found to be at risk for impaired HRQoL on emotional and school functioning. These children warrant special attention
