Isolated Voices: Perspectives of Teachers, School Nurses, and Administrators Regarding Implementation of Sexual Health Education Policy.

BackgroundComprehensive sexual health education (SHE) reduces risky sexual behavior and increases protective behavior in adolescents. It is important to understand how professionals responsible for implementing SHE policy interpret state and local policy and what influences their commitment to formal SHE policy implementation.MethodsThis descriptive study explored content and delivery of SHE policy in a rural, southwestern state with high levels of poverty, unintended adolescent pregnancy, and sexually transmitted infections. The social ecological model (SEM) was used to better understand levels of influence on the implementation of SHE policy.ResultsWe conducted telephone surveys with 38 teachers, 63 nurses, and 21 administrators in public secondary schools. There was substantial local variability in the scope and content of SHE curricula. Respondents identified significant barriers to the delivery of SHE content and minimal evaluation of whether educational objectives were met. Based on participant responses, community and organizational SEM levels had the greatest influence on SHE policy implementation, although examples of all SEM levels were identified.ConclusionsGiven perceived challenges regarding subject matter, successful SHE implementation at the local level requires committed stakeholders working in concert at the school and community levels, backed by strong policy commitment at the state level

Echocardiographic assessments of longitudinal left ventricular function in healthy English springer spaniels

OBJECTIVES: To establish reference intervals for echocardiographic measures of longitudinal left ventricular function in adult English springer spaniel dogs. ANIMALS: Forty-two healthy adult English springer spaniels. METHODS: Animals were prospectively recruited from a general practice population in the United Kingdom. Dogs were examined twice, at least 12 months apart, to exclude dogs with progressive cardiac disease. Mitral annular plane systolic excursion, tissue Doppler imaging (TDI) mitral annular velocities and two-dimensional speckle-tracking echocardiographic (2DSTE) left ventricular longitudinal strain and strain rate were measured. Intraoperator and intraobserver variability were examined and reference intervals were calculated. The potential effects of body weight, age and heart rate on these variables were examined. RESULTS: Intraoperator and intraobserver variability was <10% for all parameters except TDI E’ and 2DSTE variables, which were all <20%. Thirty-nine dogs were used to create reference intervals. Significant (but mostly weak) effects of age, heart rate and body weight on were detected. Reference intervals were similar to previously published values In different breeds. CLINICAL SIGNIFICANCE: Breed specific reference intervals for measures of longitudinal left ventricular function in the English springer spaniel are presented

Targeted youth support: Rapid Evidence Assessment of effective early interventions for youth at risk of future poor outcomes

This report describes the findings and methods of a systematic rapid evidence assessment (REA) of research relevant to interventions of interest to Targeted Youth Support. It was commissioned by the Department for Children, Schools and Families (DCSF) to inform the development of policy and practice in relation to this initiative

Pet owner and vet interactions: exploring the drivers of AMR

Background: Antimicrobial resistance (AMR) is a growing public health problem across the world. As the negative consequences of AMR become apparent at local, national and international levels, more attention is being focussed on the variety of mechanisms by which AMR is potentiated. We explore how interactions between pet owners and veterinarians represent a key arena in which AMR-related behaviours can be shaped. Methods: In depth semi-structured interviews were carried out with pet owners (n = 23) and vets (n = 16) across the UK in 2017. A thematic analysis approach was taken, with inductively gathered data analysed deductively using a behavioural framework to identified key behaviours emerging from participant accounts which were amenable to change. Results: Interactions between vets and pet owners were characterised by misunderstandings and misconceptions around antibiotics by pet owners, and a lack of clarity about the positions and intentions of the other party. Vets and pet owners had differing perceptions of where pressure to prescribe antibiotics inappropriately originated. Vets perceived it was mostly pet owners who pushed for inappropriate antibiotics, whereas pet owners reported they felt it was vets that overprescribed. Low levels of understanding of AMR in general were apparent amongst pet owners and understandings with regard to AMR in pets specifically were almost non-existent in the sample. Conclusions: Improved use of antibiotics could be assisted by educating the pet owning public and by guideline development for companion animal vets, concurrent development of mandatory legislation, increased consultation time to facilitate better communication, development of vet training on antimicrobial therapy and stewardship led interactions with pet owners, and increased levels of knowledge of pet-related AMR amongst pet owners

Youth work: a systematic map of the research literature.

This is the first systematic international map of youth work research. It provides a unique resource for investigating the content of youth work, how it is delivered and the terms in which it is assessed, both in formal evaluations of its impact and by children and young people themselves. It provides a valuable basis for developing an evidence-informed approach to policy and practice

Bipartite entangled stabilizer mutually unbiased bases as maximum cliques of Cayley graphs

We examine the existence and structure of particular sets of mutually unbiased bases (MUBs) in bipartite qudit systems. In contrast to well-known power-of-prime MUB constructions, we restrict ourselves to using maximally entangled stabilizer states as MUB vectors. Consequently, these bipartite entangled stabilizer MUBs (BES MUBs) provide no local information, but are sufficient and minimal for decomposing a wide variety of interesting operators including (mixtures of) Jamiolkowski states, entanglement witnesses and more. The problem of finding such BES MUBs can be mapped, in a natural way, to that of finding maximum cliques in a family of Cayley graphs. Some relationships with known power-of-prime MUB constructions are discussed, and observables for BES MUBs are given explicitly in terms of Pauli operators.Comment: 8 pages, 1 figur

Will Overfishing and Proposed Mississippi River Diversions Imperil Louisiana Oyster Fisheries? Commentary and Review

Two recent articles based on oyster landings have challenged the prevailing wisdom about the most important factors controlling Louisiana oyster production. One article concludes that the northern Gulf industry (principally Louisiana) will collapse based on overfishing; the second concludes that the addition of freshwater through diversions could be harmful to production. These findings are not supported by the literature or our statistical analysis of the landings data. In an effort to put into perspective the complexity of the factors affecting oyster production in the northern Gulf of Mexico, several areas of the oyster literature are reviewed, including (1) hysteresis, (2) the heterogeneous needs of different oyster ages, and (3) the geographic distribution of Gulf oyster populations (some including statistical interpretations). We conclude that Kirby’s (2004) prediction of failure of the Gulf oyster fishery as a result of the danger of current levels of fishing approaching overfishing is exaggerated. We further conclude that Turner’s (2006) data do not support his thesis that diversions are at least unjustified, if not harmful to overall oyster production
