Engaging Men and Boys to End Sexual and Gender-based Violence in Sierra Leone: A Stakeholder Mapping Report, June 2014

Increasingly, engaging with men and boys has emerged as a vital strategy adopted by non-governmental organisations, national governments, women’s organisations, and international agencies for ending sexual and gender-based violence (SGBV) and achieving gender equality, including in refugee and post-conflict settings (Barker and Ricardo 2005; Dworkin, Colvin, Hatcher and Peacock 2012). While SGBV is a global problem, recent research in West Africa suggests that this problem becomes particularly acute in post-conflict countries. In Sierra Leone, the focus of this report, it is widely estimated that during its civil war from 1991–2002, up to 250,000 women and girls were subjected to some form of SGBV (Amnesty International 2007: 4). Rape, largely but not solely by men against women, was used systematically by all factions and, although peace was declared in 2002, the trauma of war and its violent tactics has left scars that run through the fabric of households, families and communities. In order to gain a deeper understanding of the role of men and boys in addressing SGBV, in June 2014 IDS and MAGE–SL held two stakeholder workshops and a series of interviews in Sierra Leone. This report begins with a brief overview of the workshops, which form part of a larger research study on collective action and the role of men and boys in addressing SGBV in Sierra Leone. Section 4 details five of the key themes drawn from the workshops. These are: (1) the civil war as catalyst for critical awareness; (2) the economic basis of inequality in households; (3) law and policy reform; (4) inadequate support for those engaged in work to address SGBV; and (5) knowledge sharing. Section 5 maps the various stakeholders in Sierra Leone whose interests either overlap with, intersect with, or impede the work of those engaging with men and boys against SGBV; it also highlights the opportunities and challenges. Drawing from the workshop findings, Section 6 suggests why it is important to engage with men and boys to address SGBV, and Section 7 provides a concluding summary.UK Department for International Developmen

Offering and hospitality in Arabic and English

This paper examines the conventional linguistic practices involved in everyday hospitality situations. We compare offers in Arabic and English and, rather than focusing on the differences between the ways interactants in these two cultures make offers, we challenge the notion that offering is in essence differently handled in the two languages. We argue instead that we should focus just as much on the similarities between the ways offers are made, since no two cultural/linguistic groups are diametrically opposed. Furthermore, no cultural or linguistic group can be argued to be homogeneous. Through a detailed analysis of four naturally occurring hospitality encounters, we explore the nature and sequencing of offering and receiving hospitality in each cultural community and discuss the extent to which offers and refusals are conventionalized in each language. In this way we hope to develop a more contextual discursive approach to cross-cultural politeness research. Drawing on Spencer-Oatey's notion of sociality face, we examine the conventions for being hospitable in order to appear sincere. A qualitative analysis of the data reveals that, while there are similarities in offering behaviour in both English and Arabic, in Arabic, the interactional moves of insisting and refusing are slightly more conventionalized. This however does not constitute a radical difference between the offering norms of these two cultural groups

Combining Multi-Criteria Decision Making (MCDM) Methods with Building Information Modelling (BIM): A Review

Integrating building information to support decision-making has been a key challenge in the Architecture, Engineering, and Construction (AEC) industry. The synergy of Building Information Modelling (BIM) and Multi-Criteria Decision Making (MCDM) is expected to improve information integration and decision-making. The aim of this paper is to identify strategies to improve the synergy between MCDM and BIM. From the earliest literature (2009) to the present, this study examines 45 articles combining MCDM with BIM. We find that the five major application domains are sustainability, retrofit, supplier selection, safety, and constructability. Five established strategies for improving the synergy between MCDM and BIM were discussed and can be used as a benchmark for evaluating the application of decision techniques in practice. This study points out gaps of combining MCDM and BIM in the current literature. It also sheds new light into combining MCDM with BIM for practitioners, as to promote integrated decision-making

Fluorescent carbon dioxide indicators

Over the last decade, fluorescence has become the dominant tool in biotechnology and medical imaging. These exciting advances have been underpinned by the advances in time-resolved techniques and instrumentation, probe design, chemical / biochemical sensing, coupled with our furthered knowledge in biology. Complementary volumes 9 and 10, Advanced Concepts of Fluorescence Sensing: Small Molecule Sensing and Advanced Concepts of Fluorescence Sensing: Macromolecular Sensing, aim to summarize the current state of the art in fluorescent sensing. For this reason, Drs. Geddes and Lakowicz have invited chapters, encompassing a broad range of fluorescence sensing techniques. Some chapters deal with small molecule sensors, such as for anions, cations, and CO2, while others summarize recent advances in protein-based and macromolecular sensors. The Editors have, however, not included DNA or RNA based sensing in this volume, as this were reviewed in Volume 7 and is to be the subject of a more detailed volume in the near future

Detection and classification of turn fault and high resistance connection fault in permanent magnet machines based on zero sequence voltage

Health monitoring and fault detection are becoming more and more important in electrical machine systems due to the increasing demand for reliability. Winding turn fault is a common fault in permanent magnet machines which can cause severe damages and requires prompt detection and mitigation. High resistance connection (HRC) fault which result in phase asymmetry may also occur but does not require immediate shutdown. Thus, apart from the fault detection, the classification between the two faults is also required. In this paper, a new technique for detecting and classifying turn fault and HRC fault by utilizing both the high and low frequency components of the zero sequence voltage is proposed. The dependence on the operating conditions is minimized with the proposed fault indicators. The effectiveness of fault detection and classification has been verified by extensive experimental tests on a triple redundant fault tolerant permanent magnet assisted synchronous reluctance machine (PMA SynRM). The robustness of the turn fault detection in transient states and under no load conditions has also been demonstrated

Altered expression of caspases-4 and -5 during inflammatory bowel disease and colorectal cancer : diagnostic and therapeutic potential

Caspases are a group of proteolytic enzymes involved in the co-ordination of cellular processes, including cellular homeostasis, inflammation and apoptosis. Altered activity of caspases, particularly caspase-1, has been implicated in the development of intestinal diseases, such as inflammatory bowel disease (IBD) and colorectal cancer (CRC). However, the involvement of two related inflammatory caspase members, caspases-4 and -5, during intestinal homeostasis and disease has not yet been established. This study demonstrates that caspases-4 and -5 are involved in IBD-associated intestinal inflammation. Furthermore, we found a clear correlation between stromal caspase-4 and -5 expression levels, inflammation and disease activity in ulcerative colitis patients. Deregulated intestinal inflammation in IBD patients is associated with an increased risk of developing CRC. We found robust expression of caspases-4 and -5 within intestinal epithelial cells, exclusively within neoplastic tissue, of colorectal tumours. An examination of adjacent normal, inflamed and tumour tissue from patients with colitis-associated CRC confirmed that stromal expression of caspases-4 and -5 is increased in inflamed and dysplastic tissue, while epithelial expression is restricted to neoplastic tissue. In addition to identifying caspases-4 and -5 as potential targets for limiting intestinal inflammation, this study has identified epithelial-expressed caspases-4 and -5 as biomarkers with diagnostic and therapeutic potential in CRC

PWM Ripple Currents Based Turn Fault Detection for Multiphase Permanent Magnet Machines

Most permanent magnet machines are driven by inverters with pulse width modulation (PWM) voltages. The currents contain high frequency (HF) components which are inversely proportional to machine inductance. The HF PWM ripple currents can be used to detect a turn fault that gives rise to changes in inductance. The features of these HF components in turn fault conditions are analyzed. A bandpass (BP) filter is designed to extract the selected sideband components, and their root-mean-square (RMS) values are measured. The RMS values in all phases are compared. It is shown that the RMS ripple current ratios between two adjacent phases provide a very good means of detecting turn fault with high signal-to-noise ratio. The detection method can identify the faulted phase, tolerate inherent imbalance of the machine, and is hardly affected by transient states. The method is assessed by simulations and experiments on a five-phase permanent magnet machine
