Domestic abuse and safeguarding children : critical issues for multiagency work

This paper reports upon the learning that emerged from a development project which aimed to facilitate improvements in multiagency work in domestic abuse and safeguarding children. The two-year project (2011–13), funded by the Department for Education and led by WomenCentre, a specialist voluntary sector organisation based in West Yorkshire, was undertaken in nine local authorities in the north of England. Activities undertaken during the project included case mapping, service user and professional engagement exercises, observation of local multiagency meetings and provision of training. An evaluative research study examined the work of the project and the learning that emerged. Drawing upon data from telephone interviews with project participants, analysis of case mapping and project reports, this paper discusses some critical issues which emerged from this project. The paper draws attention to the different understandings and priorities which shape interprofessional practice in relation to safeguarding children and domestic abuse, and the complexities of the wider interagency environment including coordination, resources and expertise. Recommendations for improving multiagency work to achieve better outcomes for women and children experiencing domestic abuse are discussed

Survey on Om Meditation: Its Effects on the Human Body and Om Meditation as a Tool for Stress Management

Meditation and yoga both have positive effects on physical, as well as mental health. Om mantra chanting, a simple and easy to practice, also comes under the aspect of meditation. The “Om” mantra is also considered as the very name of the absolute. Om meditation not only affects the various parts of the brain, such as pre-frontal cortex, vagus nerve, amygdala and others but also affects the heart rate and respiratory rate. Considering the healing effects of Om meditation, through this paper, we are trying to explore all the relevant work done in the field of Om meditation. The survey includes a large number of papers covering the research previously conducted by many researchers, their results and different techniques adopted to study the effect of Om meditation on human beings. Studies on Om meditation are categorized under four different heads: Neuroimaging studies, EEG studies, evoked potentials studies and other methods studies. Even though the existing research evidenced capability of Om meditation in curing anxiety and depression, more rigorous studies with better design, with larger sample size and with different control groups are required. Especially the need to explore untouched research areas of Loud Om meditation using EEG is suggested in the paper. Furthermore, future research directions are also suggested

Motor activity dependent and independent functions for Myosin II in cytokinesis contribute to actomyosin ring assembly and contraction in Schizosaccharomyces pombe

Cytokinesis depends on a contractile actomyosin ring in many eukaryotes [1, 2, 3]. Myosin II is a key component of the actomyosin ring, although whether it functions as a motor or as an actin cross-linker to exert its essential role is disputed [1, 4, 5]. In Schizosaccharomyces pombe, the myo2-E1 mutation affects the upper 50 kDa sub-domain of the myosin II heavy chain, and cells carrying this lethal mutation are defective in actomyosin ring assembly at the non-permissive temperature [6, 7]. myo2-E1 also affects actomyosin ring contraction when rings isolated from permissive temperature-grown cells are incubated with ATP [8]. Here we report isolation of a compensatory suppressor mutation in the lower 50 kDa sub-domain (myo2-E1-Sup1) that reverses the inability of myo2-E1 to form colonies at the restrictive temperature. myo2-E1-Sup1 is capable of assembling normal actomyosin rings, although rings isolated from myo2-E1-Sup1 are defective in ATP-dependent contraction in vitro. Furthermore, the product of myo2-E1-Sup1 does not translocate actin filaments in motility assays in vitro. Superimposition of myo2-E1 and myo2-E1-Sup1 on available rigor and blebbistatin-bound myosin II structures suggests that myo2-E1-Sup1 may represent a novel actin translocation-defective allele. Actomyosin ring contraction and viability of myo2-E1-Sup1 cells depend on the late cytokinetic S. pombe myosin II isoform, Myp2p, a non-essential protein that is normally dispensable for actomyosin ring assembly and contraction. Our work reveals that Myo2p may function in two different and essential modes during cytokinesis: a motor activity-independent form that can promote actomyosin ring assembly and a motor activity-dependent form that supports ring contraction

A Miniature Coupled Bistable Vibration Energy Harvester

This paper reports the design and test of a miniature coupled bistable vibration energy harvester. Operation of a bistable structure largely depends on vibration amplitude rather than frequency, which makes it very promising for wideband vibration energy harvesting applications. A coupled bistable structure consists of a pair of mobile magnets that create two potential wells and thus the bistable phenomenon. It requires lower excitation to trigger bistable operation compared to conventional bistable structures. Based on previous research, this work focused on miniaturisation of the coupled bistable structure for energy harvesting application. The proposed bistable energy harvester is a combination of a Duffing’s nonlinear structure and a linear assisting resonator. Experimental results show that the output spectrum of the miniature coupled bistable vibration energy harvester was the superposition of several spectra. It had a higher maximum output power and a much greater bandwidth compared to simply the Duffing’s structure without the assisting resonato

Analysis of the progeny of sibling matings reveals regulatory variation impacting the transcriptome of immune cells in commercial chickens

There is increasing recognition that the underlying genetic variation contributing to complex traits influences transcriptional regulation and can be detected at a population level as expression quantitative trait loci. At the level of an individual, allelic variation in transcriptional regulation of individual genes can be detected by measuring allele-specific expression in RNAseq data. We reasoned that extreme variants in gene expression could be identified by analysis of inbred progeny with shared grandparents. Commercial chickens have been intensively selected for production traits. Selection is associated with large blocks of linkage disequilibrium with considerable potential for co-selection of closely linked “hitch-hiker alleles” affecting traits unrelated to the feature being selected, such as immune function, with potential impact on the productivity and welfare of the animals. To test this hypothesis that there is extreme allelic variation in immune-associated genes we sequenced a founder population of commercial broiler and layer birds. These birds clearly segregated genetically based upon breed type. Each genome contained numerous candidate null mutations, protein-coding variants predicted to be deleterious and extensive non-coding polymorphism. We mated selected broiler-layer pairs then generated cohorts of F2 birds by sibling mating of the F1 generation. Despite the predicted prevalence of deleterious coding variation in the genomic sequence of the founders, clear detrimental impacts of inbreeding on survival and post-hatch development were detected in only one F2 sibship of 15. There was no effect on circulating leukocyte populations in hatchlings. In selected F2 sibships we performed RNAseq analysis of the spleen and isolated bone marrow-derived macrophages (with and without lipopolysaccharide stimulation). The results confirm the predicted emergence of very large differences in expression of individual genes and sets of genes. Network analysis of the results identified clusters of co-expressed genes that vary between individuals and suggested the existence of trans-acting variation in the expression in macrophages of the interferon response factor family that distinguishes the parental broiler and layer birds and influences the global response to lipopolysaccharide. This study shows that the impact of inbreeding on immune cell gene expression can be substantial at the transcriptional level, and potentially opens a route to accelerate selection using specific alleles known to be associated with desirable expression levels

On the dynamics of a nonlinear energy harvester with multiple resonant zones

The dynamics of a nonlinear vibration energy harvester for rotating systems is investigated analytically through harmonic balance, as well as by numerical analysis. The electromagnetic harvester is attached to a spinning shaft at constant speed. Magnetic levitation is used as the system nonlinear restoring force for broadening the resonant range of the oscillator. The system is modelled as a Duffing oscillator with linear frequency variation under static, as well as harmonic excitation. Behaviour charts and backbone curves are extracted for the fundamental harmonic response and validated against frequency response curves for selected cases, using direct numerical integration. It is found that variation in stiffness, together with asymmetric forcing, gives rise to a novel structure of multiple resonant zones, incorporating mono-stable and bi-stable dynamics. Contrary to previously considered bi-stable energy harvesters, cross-well oscillations are realized through a transition from single-well potential energy to double-well with forward frequency sweep. Furthermore, in-well_oscillations present a hardening behaviour, unlike the well-known softening in-well response of bi-stable Duffing oscillators. The analysis shows that the proposed system has multiple resonant responses to a frequency sweep, influenced by consecutive interacting backbone curves similar to a multi-modal system. This combined effect of the transition to bi-stable dynamics and the hardening in-well oscillations induces resonant response of the harvester over multiple distinct frequency ranges. Thus, the system exhibits a broadened frequency response, enhancing its energy harvesting potential

Smoke and Mirrors: U.K. Newspaper Representations of Intimate Partner Domestic Violence

This is a pre-copyedited, author-produced pdf of an article accepted for publication in Violence Against Women following peer review. The final, definitive version of this paper has been published in Violence Against Women, Vol 23 (1): 114-139, first published April 2016 by SAGE Publishing, and is available on line at doi: 10.1177/1077801216634468. All rights reserved.News media are in a position to project certain perspectives on domestic violence while marginalizing others, which has implications for public understanding and policy development. This study applies discourse analysis to articles on domestic violence in two U.K. national daily newspapers published in 2001-2002 and 2011-2012 to evaluate evidence of change over a 10-year time span. The research examines how discourses of domestic violence are constructed through newspaper representations of victims, predominantly women, and perpetrators, predominantly men. Although one of the newspapers adopts a respectful position toward women, the textual and visual techniques adopted by the other reveal a tendency for blaming the victim and sexualizing violence related to perceptions of “deserving” or “undeserving” women victims.Peer reviewe
