Levels of Abstractness in Semantic Noun and Verb Processing:The Role of Sensory‑Perceptual and Sensory‑Motor Information

Effects of concreteness and grammatical class on lexical-semantic processing are well-documented, but the role of sensory-perceptual and sensory-motor features of concepts in underlying mechanisms producing these effects is relatively unknown. We hypothesized that processing dissimilarities in accuracy and response time performance in nouns versus verbs, concrete versus abstract words, and their interaction can be explained by differences in semantic weight—the combined amount of sensory-perceptual and sensory-motor information to conceptual representations—across those grammatical and semantic categories. We assessed performance on concrete and abstract subcategories of nouns and verbs with a semantic similarity judgment task. Results showed that when main effects of concreteness and grammatical class were analyzed in more detail, the grammatical-class effect, in which nouns are processed more accurately and quicker than verbs, was only present for concrete words, not for their abstract counterparts. Moreover, the concreteness effect, measured at different levels of abstract words, was present for both nouns and verbs, but it was less pronounced for verbs. The results do not support the grammatical-class hypothesis, in which nouns and verbs are separately organized, and instead provide evidence in favor of a unitary semantic space, in which lexical-semantic processing is influenced by the beneficial effect of sensory-perceptual and sensory-motor information of concepts

Recent intimate partner violence against women and health: a systematic review and meta-analysis of cohort studies.

OBJECTIVE: We reviewed cohort studies to determine the magnitude and temporal direction of the association between recent intimate partner violence (IPV) and a range of adverse health outcomes or health risk behaviours. DESIGN: Systematic review and meta-analysis. METHODS: Medline, EMBASE and PsycINFO were searched from the first record to November 2016. Recent IPV was defined as occurring up to and including the last 12 months; all health outcomes were eligible for inclusion. Results were combined using random-effects meta-analysis. RESULTS: 35 separate cohort studies were retrieved. Eight studies showed evidence of a positive association between recent IPV and subsequent depressive symptoms, with a pooled OR from five estimates of 1.76 (95% CI 1.26 to 2.44, I2=37.5%, p=0.172). Five studies demonstrated a positive, statistically significant relationship between depressive symptoms and subsequent IPV; the pooled OR from two studies was 1.72 (95% CI 1.28 to 2.31, I2=0.0%, p=0.752). Recent IPV was also associated with increased symptoms of subsequent postpartum depression in five studies (OR=2.19, 95% CI 1.39 to 3.45, p=0.000), although there was substantial heterogeneity. There was some evidence of a bidirectional relationship between recent IPV and hard drug use and marijuana use, although studies were limited. There was no evidence of an association between recent IPV and alcohol use or sexually transmitted infections (STIs), although there were few studies and inconsistent measurement of alcohol and STIs. CONCLUSIONS: Exposure to violence has significant impacts. Longitudinal studies are needed to understand the temporal relationship between recent IPV and different health issues, while considering the differential effects of recent versus past exposure to IPV. Improved measurement will enable an understanding of the immediate and longer term health needs of women exposed to IPV. Healthcare providers and IPV organisations should be aware of the bidirectional relationship between recent IPV and depressive symptoms. PROSPERO REGISTRATION NUMBER: CRD42016033372

Recognition of Membrane Sterols by Polyene Antifungals Amphotericin B and Natamycin, A 13C MAS NMR Study

The molecular action of polyene macrolides with antifungal activity, amphotericin B and natamycin, involves recognition of sterols in membranes. Physicochemical and functional studies have contributed details to understanding the interactions between amphotericin B and ergosterol and, to a lesser extent, with cholesterol. Fewer molecular details are available on interactions between natamycin with sterols. We use solid state 13C MAS NMR to characterize the impact of amphotericin B and natamycin on mixed lipid membranes of DOPC/cholesterol or DOPC/ergosterol. In cholesterol-containing membranes, amphotericin B addition resulted in marked increase in both DOPC and cholesterol 13C MAS NMR linewidth, reflecting membrane insertion and cooperative perturbation of the bilayer. By contrast, natamycin affects little either DOPC or cholesterol linewidth but attenuates cholesterol resonance intensity preferentially for sterol core with lesser impact on the chain. Ergosterol resonances, attenuated by amphotericin B, reveal specific interactions in the sterol core and chain base. Natamycin addition selectively augmented ergosterol resonances from sterol core ring one and, at the same time, from the end of the chain. This puts forward an interaction model similar to the head-to-tail model for amphotericin B/ergosterol pairing but with docking on opposite sterol faces. Low toxicity of natamycin is attributed to selective, non-cooperative sterol engagement compared to cooperative membrane perturbation by amphotericin B

“It’s always good to ask”: a mixed methods study on the perceived role of sexual health practitioners asking gay and bisexual men about experiences of domestic violence and abuse

Development of joint displays is a valued approach to merging qualitative and quantitative findings in mixed methods research. This study aimed to illustrate a case series mixed methods display and the utility of using mixed methods for broadening our understanding of domestic violence and abuse. Using a convergent design, 532 gay and bisexual men participated in a Health and Relationship Survey in a U.K. sexual health service and 19 in an interview. Quantitative and qualitative data were analyzed separately and integrated at the level of interpretation and reporting. There were inconsistencies in perceptions and reports of abuse. Men were supportive of selective enquiry for domestic violence and abuse by practitioners (62.6%; 95% confidence interval = 58.1% to 66.7%) while being mindful of contextual factors

"It Doesn't Freak Us Out the Way It Used to": An Evaluation of the Domestic Violence Enhanced Home Visitation Program to Inform Practice and Policy Screening for IPV.

The Domestic Violence Enhanced Home Visitation (DOVE) intervention used in the Perinatal Nurse Home Visiting Intervention Enhanced With mHealth Technology (RCT: R01HD071771) is a nurse-lead evidenced-based intervention that has been shown to decrease violence overtime. This summative mixed-methods impact evaluation is intended to provide insight to enhance the DOVE IPV protocol for screening and intervention by (a) identifying which core aspects of DOVE facilitated or inhibited its success and what was most critical to optimal IPV (intimate partner violence) screening and intervention practices, (b) informing how DOVE IPV screening and intervention were influenced by the experiences of home visitor (HV), and (c) identifying policy considerations and best practice recommendations for the DOVE protocol. Participants were HVs and managers (N = 13) in rural/urban home visiting programs delivering DOVE across three states. The sample had a mean age of 48.76. Three fourths were baccalaureate-prepared nurses with an average of 10.5 years of home visiting experience. The method used in this study was one-to-one qualitative in-depth interviews with HVs. Data were interpretively analyzed using Nvivo 10 to generate three themes. Participants endorsed screening women for IPV with DOVE being the approach of choice to facilitate IPV screening and intervening with women. HVs found DOVE helped enhance their IPV knowledge, screening, and intervening capabilities while filling an existing void in this type of preparation of HV nurses. Establishing a relationship with the women before initiating screening was an important aspect in delivering DOVE as was the training, support, and increased comfort level in addressing IPV. The evidence offers an understanding of which core aspects of DOVE contributed to its success and what was most critical to optimal IPV screening and intervention practices. Furthermore, this evaluation provided multilevel insights into how best to advance home visiting practices and policies when screening and intervening with perinatal women exposed to IPV

Servidor web multiplataforma con implementación CGI

El objetivo que perseguimos en este trabajo fue el desarrollo de un servidor Web multiplataforma basado en el protocolo HTTP 1.0 con implementación de la interfaz CGI, utilizando como lenguaje de programación JAVA. Los métodos que implementa son GET, HEAD, POST, PUT, DELETE .También dotamos al servidor con la capacidad de entender y responder a peticiones de clientes que utilicen protocolo HTTP 0.9 (GET) y HTTP 1.1 (GET, HEAD, POST, PUT, DELETE, OPTIONS, TRACE). Desarrollamos también un administrador del servidor que permitiera, a la persona que lo administrara, decidir dónde se encontrarían los recursos que podrían ser accedidos a través del servidor y si éstos serían de libre acceso o de acceso restringido; todo esto a través de una interfaz gráfica. Y como complemento, decidimos construir un cliente web que permitiera subir (upload) y bajar (download) archivos en un servidor y otros métodos que navegadores comerciales no implementaban.Eje: Sistemas operativosRed de Universidades con Carreras en Informática (RedUNCI
