Effect of Volume of Heat Sink on Process and Physical Properties of Parts Built by Welding Based SFF

A new numerical simulation of the effect of the volume of the heat sink on the welding–based deposition process is performed. For this purpose, the ANSYS parametric design language (APDL) is applied. Due to the complex internal and/or external shapes of the designed threedimensional (3D) part, different heat transfer conditions are met during the building process. The influences of the different heat transfer conditions on the physical part properties are also investigated. The influence of the volume of the heat sink on the process and on the physical properties is significant and can not be neglected. Extensive experiments are designed and executed in order to verify the conclusions derived from the finite elements model results and to investigate the material properties of the built part.Mechanical Engineerin

Sustaining a Collegiate Environment: Colleagueship, Community and Choice at an Anonymous Business School

The increasing push towards centralisation and bureaucratisation in higher education, further exacerbated by the disruption caused by the COVID-19 pandemic, calls for a better understanding of the nature of collegiality in contemporary universities. We address this issue by looking into the necessary conditions and barriers to sustaining a collegiate environment. The empirical focus is on academics, academic leaders and professional support staff at Anonymous Business School (ABS), a department in a large civic UK university. We interviewed 32 participants across the school, ranging from early-career academics to experienced professors and members of department leadership teams. The findings suggest multiple emerging perspectives on collegiality, with features of horizontal collegiality perceived as key to successful academic responses to the crisis. The findings also indicate how sustaining a collegiate environment within the department requires both choice and effort from leadership and from staff, particularly when decision-making is primarily located at the centre of the university. The choice and effort made across different collegiate pockets contribute to the department becoming an ‘island of collegiality’ within the increasingly centralised and bureaucratised university hierarchy. In this sense, the actions of the department leadership to establish supporting mechanisms, and the actions of the staff to, in turn, embrace and build interpersonal relationships and professional identities, are key to sustaining a collegiate environment

Writing the history of the present

This is an accepted manuscript of an article published by Springer in Postdigital Science and Education on 22/07/2020. The accepted version of the publication may differ from the final published version.Teaching in The Age of Covid-19 ‘Teaching in The Age of Covid-19’ (Jandrić et al. 2020) presents 80 textual testimonies and 79 home workspace photographs submitted by 83 authors from 19 countries. Collected between 18 March and 5 May 2020, the testimonies and photographs describe uncanny feelings, daily experiences and challenges, and emergency solutions, developed by worldwide academics at the very beginning of the Covid-19 pandemic. Supplemented with one editor’s introduction at the beginning, and another editor’s reflections at the end, these messy and unpredictable texts and images have now obtained the form of a ‘proper’ piece of academic writing. Yet appearance deceives; as we found out early into the project, this collection can be read in many different ways. At a time when local and global surveys are contributing insights on how the move to online learning and teaching is being experienced (Watermeyer et al. 2020), we explain why this particular collection is both different, but also complementary, to other studies. Each contribution to ‘Teaching in The Age of Covid-19’ (Jandrić et al. 2020) is a standalone authored work, that is both distinct and diverse. Some texts and images are small artistic masterpieces; others more focused to the ‘scientific’ side of things; and many contributions, neither particularly artistic nor very scholarly, provide a wealth of insights into the everyday life and practice of teachers and students during the very beginning of lockdown. We have a lot of appreciation for great arts, and new ideas are the bread and butter of academic inquiry. Yet ‘Teaching in The Age of Covid-19’ is not primarily about beautiful storytelling and / or novel ideas

Dispositional Mindfulness, Meditation, and Conditional Goal Setting

Conditional goal setting (CGS, the tendency to regard high order goals such as happiness, as conditional upon the achievement of lower order goals) is observed in individuals with depression and recent research has suggested a link between levels of dispositional mindfulness and conditional goal setting in depressed patients. Since interventions which aim to increase mindfulness through training in meditation are used with patients suffering from depression it is of interest to examine whether such interventions might alter CGS. Study 1 examined the correlation between changes in dispositional mindfulness and changes in CGS over a 3-4 month period in patients participating in a pilot randomised controlled trial of Mindfulness-Based Cognitive Therapy (MBCT). Results indicated that increases in dispositional mindfulness were significantly associated with decreases in CGS, although this effect could not be attributed specifically to the group who had received training in meditation. Study 2 explored the impact of brief periods of either breathing or loving kindness meditation on CGS in 55 healthy participants. Contrary to expectation, a brief period of meditation increased CGS. Further analyses indicated that this effect was restricted to participants low in goal re-engagement ability who were allocated to loving kindness meditation. Longer term changes in dispositional mindfulness are associated with reductions in CGS in patients with depressed mood. However initial reactions to meditation, and in particular loving kindness meditation, may be counterintuitive and further research is required in order to determine the relationship between initial reactions and longer-term benefits of meditation practice
