An ‘objective-centred’ approach to course redesign: using learning objectives to integrate e-learning

This article describes the process of integrating e-learning into the M-level research methods course Research Synthesis for Policy and Practice. It explores an ‘objective-centred’ approach to course redesign. This entails using learning objectives as the basis for developing online activities and integrating technological tools. This article describes what this ‘objectives approach’ meant in practice and illustrates the importance of learning objectives for the redesign process. Embedding elearning into the course provides new opportunities to meet existing objectives in an innovative, and hopefully more effective, way. Technological tools provide the scope to extend and develop new learning objectives to better meet the needs of students. Whilst objectives are central to the redesign, the article highlights the significant role played by other types of knowledge, namely tutor experience, student views and research

Women academics publish less than men. Or do they…?

Publishing can sometimes be seen as acting as the fuel behind the academic world. Yet, across social sciences, woman are not publishing their share of research papers. Karen Schucan-Bird fears that if they are not publishing at a level comparable to their male counterparts, women are left standing at a career disadvantage

Reactive self-heating model of aluminum spherical nanoparticles

Aluminum-oxygen reaction is important in many highly energetic, high pressure generating systems. Recent experiments with nanostructured thermites suggest that oxidation of aluminum nanoparticles occurs in a few microseconds. Such rapid reaction cannot be explained by a conventional diffusion-based mechanism. We present a rapid oxidation model of a spherical aluminum nanoparticle, using Cabrera-Mott moving boundary mechanism, and taking self-heating into account. In our model, electric potential solves the nonlinear Poisson equation. In contrast with the Coulomb potential, a "double-layer" type solution for the potential and self-heating leads to enhanced oxidation rates. At maximal reaction temperature of 2000 C, our model predicts overall oxidation time scale in microseconds range, in agreement with experimental evidence.Comment: submitte

Ethically Driven and Methodologically Tailored: Setting the Agenda for Systematic Reviews in Domestic Violence and Abuse

PURPOSE: Systematic reviews have an important, and growing, role to play in the global evidence eco-system of domestic violence and abuse. Alongside substantive contributions to knowledge, such reviews stimulate debates about ethical reviewing practices and the importance of tailoring methods to the nuances of the field. This paper aims to pinpoint a set of ethical and methodological priorities to guide and enhance review practices specifically in the field of domestic abuse. METHOD: The five Pillars of the Research Integrity Framework (ethical guidelines for domestic abuse research) are used to interrogate the systematic review process. To do so, the Framework is retrospectively applied to a recently completed systematic review in domestic abuse. The review included a rapid systematic map and in-depth analysis of interventions aimed at creating or enhancing informal support and social networks for victim-survivors of abuse. RESULTS: Ethical and methodological priorities for systematic reviews in domestic abuse include (1) Safety and wellbeing: maintaining the wellbeing of researchers and stakeholders, and appraising the ethics of included studies, (2) Transparency/ accountability: transparent reporting of research funding, aims and methods together with explicit consideration of authorship of outputs, (3) Equality, human rights and social justice: developing diverse review teams/ Advisory groups, and review methods that aim to search for, and report, diverse perspectives. Considering researcher positionality/ reflexivity in the review, (4) Engagement: collaboration with non-academic stakeholders and individuals with lived experience throughout the review process, (5) Research Ethics: independent ethical scrutiny of systematic review proposals with input from researchers with expertise in systematic reviews and domestic abuse. CONCLUSION: Additional research is required to comprehensively examine the ethics of each stage of the review process. In the meantime, attention should be given to the underpinning ethical framework for our systematic review practices and the wider research infrastructure that governs reviews

Engineering a high-affinity methyl-CpG-binding protein

Core members of the MBD protein family (MeCP2, MBD1, MBD2 and MBD4) share a methyl-CpG-binding domain that has a specific affinity for methylated CpG sites in double-stranded DNA. By multimerizing the MDB domain of Mbd1, we engineered a poly-MBD protein that displays methyl-CpG-specific binding in vitro with a dissociation constant that is >50-fold higher than that of a monomeric MBD. Poly-MBD proteins also localize to methylated foci in cells and can deliver a functional domain to reporter constructs in vivo. We propose that poly-MBD proteins are sensitive reagents for the detection of DNA methylation levels in isolated native DNA and for cytological detection of chromosomal CpG methylatio
