Domestic abuse victims’ perceptions of abuse and support: a narrative study

The current study sought to investigate the developmental and social characteristics of a group of victimised women to develop understanding into the factors which put local women at risk for victimisation and enhance the local support services for these women. Twelve women from local support services were interviewed about their experiences of violence. The aim of these interviews was to identify patterns within these women’s narratives which can be explored and developed for future applications Interviews were analysed using thematic analysis which resulted in four themes: (1) childhood characteristics; (2) first sexual encounters; (3) quality of life; and (4) supporting services. The results provide an extraordinary opportunity to enhance the support services provided for vulnerable women and girls in the local community. These results have not only aided in advancing the current research but also developing current service-providers for this local population. More specifically, the results have indicated a number of characteristics which place women at risk of victimisation, more importantly, the results have demonstrated the importance of exploring other services that may be beneficial for the recovery of these woman. In essence, the woman taking part in this study highlighted areas which encourage future exploration for both researchers and service providers. Clearly, before definite conclusions can be drawn, more research evaluations need to be carried out to explore the characteristics that put women at risk of violence and the services which may aid in their recovery

Exploring the belief systems of domestic abuse victims using Smallest Space Analysis (SSA)

Research exploring domestic abuse victims has primarily focused on the shorter term avenues of support for victims and the risk factors which put women at risk of victimization. There is limited research exploring the belief systems of domestically abused women that need to be targeted to achieve longer term effects. The present study therefore explored the association between the beliefs of abused women and their experiences as victims. Twenty-one women with a history of domestic abuse were asked about their attitudes towards authority figures and perceived opportunities around the time of their abusive experience. Data were analyzed using Smallest Space Analysis (SSA). Four distinct belief themes (personal responsibility, antisocial attitudes, environmental factors, and negative police attitudes) were found in the analysis. The findings highlighted not only the importance of considering the long standing and personalized beliefs of abuse victims, but also demonstrates the need for support services to offer more personalized support to abuse victims to help change their belief systems. Although this research sets the groundwork in understanding the beliefs of domestic abuse victims, these results need to be built upon with future research examining the wider implications of targeting the belief systems of domestically abused women

Food consumption within Greek households: further evidence from a national representative sample

The aim of this study is to characterize the relationship between food consumption and socio-demographic characteristics in several groups of individuals. This is achieved by capturing the quantity of food purchased in categories on a microeconomic level. The empirical analysis is approached through the estimation of (a) expanded generalized linear models, (b) quantile regression models, (c) quadratic almost ideal demand system models and (d) Deaton’s (1988) approach. The results reveal that the composition of a household has a significant impact on the quantity of food consumed. In addition, price and income elasticities are estimated, confirming that the majority of food items are inelastic with respect to price and income except for meat. These findings can be used as a basis for considering food policy implications while evaluating the potential gains from applying specific policies

ACCURATE 3D SCANNING OF DAMAGED ANCIENT GREEK INSCRIPTIONS FOR REVEALING WEATHERED LETTERS

In this paper two non-invasive non-destructive alternative techniques to the traditional and invasive technique of squeezes are presented alongside with specialized developed processing methods, aiming to help the epigraphists to reveal and analyse weathered letters in ancient Greek inscriptions carved in masonry or marble. The resulting 3D model would serve as a detailed basis for the epigraphists to try to decipher the inscription. The data were collected by using a Structured Light scanner. The creation of the final accurate three dimensional model is a complicated procedure requiring large computation cost and human effort. It includes the collection of geometric data in limited space and time, the creation of the surface, the noise filtering and the merging of individual surfaces. The use of structured light scanners is time consuming and requires costly hardware and software. Therefore an alternative methodology for collecting 3D data of the inscriptions was also implemented for reasons of comparison. Hence, image sequences from varying distances were collected using a calibrated DSLR camera aiming to reconstruct the 3D scene through SfM techniques in order to evaluate the efficiency and the level of precision and detail of the obtained reconstructed inscriptions. Problems in the acquisition processes as well as difficulties in the alignment step and mesh optimization are also encountered. A meta-processing framework is proposed and analysed. Finally, the results of processing and analysis and the different 3D models are critically inspected and then evaluated by a specialist in terms of accuracy, quality and detail of the model and the capability of revealing damaged and ”hidden” letters

Quantitative identification of functional connectivity disturbances in neuropsychiatric lupus based on resting-state fMRI: a robust machine learning approach

Neuropsychiatric systemic lupus erythematosus (NPSLE) is an autoimmune entity comprised of heterogenous syndromes affecting both the peripheral and central nervous system. Research on the pathophysiological substrate of NPSLE manifestations, including functional neuroimaging studies, is extremely limited. The present study examined person-specific patterns of whole-brain functional connectivity in NPSLE patients (n = 44) and age-matched healthy control participants (n = 39). Static functional connectivity graphs were calculated comprised of connection strengths between 90 brain regions. These connections were subsequently filtered through rigorous surrogate analysis, a technique borrowed from physics, novel to neuroimaging. Next, global as well as nodal network metrics were estimated for each individual functional brain network and were input to a robust machine learning algorithm consisting of a random forest feature selection and nested cross-validation strategy. The proposed pipeline is data-driven in its entirety, and several tests were performed in order to ensure model robustness. The best-fitting model utilizing nodal graph metrics for 11 brain regions was associated with 73.5% accuracy (74.5% sensitivity and 73% specificity) in discriminating NPSLE from healthy individuals with adequate statistical power. Closer inspection of graph metric values suggested an increased role within the functional brain network in NSPLE (indicated by higher nodal degree, local efficiency, betweenness centrality, or eigenvalue efficiency) as compared to healthy controls for seven brain regions and a reduced role for four areas. These findings corroborate earlier work regarding hemodynamic disturbances in these brain regions in NPSLE. The validity of the results is further supported by significant associations of certain selected graph metrics with accumulated organ damage incurred by lupus, with visuomotor performance and mental flexibility scores obtained independently from NPSLE patients.

A 2:1 cocrystal of the cis and trans isomers of bis­[1,1,1,5,5,5-hexa­fluoro­pentane-2,4-dionato(1−)-κ2 O,O′]bis­(4-phenyl­pyridine N-oxide-κO)copper(II)

The title compound is a co-crystal of the cis and trans isomers, namely cis-bis­[1,1,1,5,5,5-hexa­fluoro­pentane-2,4-dionato(1−)-κ2 O,O′]bis­(4-phenyl­pyridine N-oxide-κO)copper(II)–trans-bis­[1,1,1,5,5,5-hexa­fluoro­pentane-2,4-dionato(1−)-κ2 O,O′]bis(4-phenyl­pyridine N-oxide-κO)copper(II) (2/1), [Cu(C5HF6O2)2(C11H9NO)2]. In both isomers, the coordination geometry of the Cu2+ atom is octa­hedral, exhibiting typical Jahn–Teller distortion. The metal atom of the trans isomer is located on an inversion centre. In the cis isomer, the phenyl ring in one 4-phenyl­pyridine N-oxide ligand is disordered over two orientations in a 1:1 ratio. In the crystal, weak inter­molecular C—H⋯F and C—H⋯O contacts establish connections between the cis and trans isomers

Rearing in captivity affects spermatogenesis and sperm quality in greater amberjack, Seriola dumerili (Risso, 1810)

The greater amberjack, Seriola dumerili (Risso, 1810), is a promising candidate for the diversification of European aquaculture production, but inconsistent reproduction in captivity prevents commercial production. Recent studies showed that greater amberjack confined in sea cages exhibited scarce gonad development and early interruption of gametogenic activity during the reproductive season. The aim of the present study was to improve our understanding of the observed impairment of spermatogenesis. Adult wild and captive-reared males were sampled during 3 different phases of the reproductive cycle: early gametogenesis (EARLY; late April to early May), advanced gametogenesis (ADVANCED; late May to early June), and spawning (SPAWNING; late June to July). Spermatogonial stem cells and proliferating germ cells were identified through the immunohistochemical localization of Pou5f1 and proliferating cell nuclear antigen, respectively. Apoptotic germ cells were identified throughout the terminal deoxynucleotidyl transferase-mediated 2â -deoxyuridine 5â -triphosphate nick end labeling method. Sperm quality of captive-reared fish was evaluated using computer-assisted sperm analysis. Captive-reared males exhibited seminiferous lobules of a smaller diameter, a precocious and progressive decrease of spermatogonial mitosis, and a high level of apoptosis at the beginning of the reproductive season, concomitant with a many-fold higher 17β-estradiol plasma concentration. The motile spermatozoa percentage of captive greater amberjack was lower than in other teleosts, and a drastic decrease of spermatozoa motility duration, velocity, and ATP content occurred along the reproductive season. An abnormal increase of sperm concentration as well as an increase of dead spermatozoa occurred during the SPAWNING phase, probably because of lack of sperm hydration and ejaculation and consequent sperm ageing. The present study demonstrates the extreme susceptibility of greater amberjack to rearing stress and underscores the need for improvement of the rearing and handling procedures to ameliorate gametogenesis dysfunctions in commercial aquaculture production
