An investigative study into the sensitivity of different partial discharge φ-q-n pattern resolution sizes on statistical neural network pattern classification

This paper investigates the sensitivity of statistical fingerprints to different phase resolution (PR) and amplitude bins (AB) sizes of partial discharge (PD) φ-q-n (phase-amplitude-number) patterns. In particular, this paper compares the capability of the ensemble neural network (ENN) and the single neural network (SNN) in recognizing and distinguishing different resolution sizes of φ-q-n discharge patterns. The training fingerprints for both the SNN and ENN comprise statistical fingerprints from different φ-q-n measurements. The result shows that there exists statistical distinction for different PR and AB sizes on some of the statistical fingerprints. Additionally, the ENN and SNN outputs change depending on training and testing with different PR and AB sizes. Furthermore, the ENN appears to be more sensitive in recognizing and discriminating the resolution changes when compared with the SNN. Finally, the results are assessed for practical implementation in the power industry and benefits to practitioners in the field are highlighted

Comparing ST-segment elevation myocardial infarction care between patients residing in central and remote locations: a retrospective case series.

People who experience an ST-elevation myocardial infarction (STEMI) due to an occluded coronary artery require prompt treatment. Treatments to open a blocked artery are called reperfusion therapies (RTs), and can include intravenous pharmacological thrombolysis (TL) or primary percutaneous coronary intervention (pPCI) in a cardiac catheterisation laboratory (cath lab). Optimal RT (ORT) with pPCI or TL reduces morbidity and mortality. In remote areas, a number of geographical and organisational barriers may influence access to ORT. These are not well understood, and the exact proportion of patients who receive ORT - and the relationship to time of day and remoteness from the cardiac cath lab - is unknown. The aim of this retrospective study was to compare the characteristics of ORT delivery in central and remote locations in the north of Scotland, and to identify potential barriers to optimal care with a view to service redesign. The study was set in the north of Scotland. All patients who attended hospital with a STEMI between March 2014 and April 2015 were identified from national coding data. A data collection form was developed by the research team in several iterative stages. Clinical details were collected retrospectively from patients' discharge letters. Data included treatment location, date of admission, distance of patient from the cath lab, route of access to health care, left ventricular function and RT received. Distance of patients from the cath lab was described as remote if they were more than ninety minutes of driving time from the cardiac cath lab, and described as central if they were ninety minutes or less of driving time from the regional centre. For patients who made contact in a pre-hospital setting, ORT was defined as pre-hospital TL (PHT) or pPCI. For patients who self-presented to the hospital first, ORT was defined as in-hospital TL or pPCI. Data were described as mean (standard deviation) as appropriate. Chi-squared and student's t-test were used as appropriate. Each case was reviewed to determine if ORT was received; if ORT was not received, the reasons for this were recorded to identify potentially modifiable barriers. Of the 627 acute myocardial infarction patients initially identified, 131 had a STEMI, and the others were non-STEMI. From this STEMI cohort, 82 (62%) patients were classed as central and 49 (38%) were remote. In terms of initial therapy, 26 (20%) received pPCI, 19 (15%) received PHTs, 52 (40%) received in-hospital TL, while 33 (25%) received no initial RT. ORT was received by 53 (65%) central and 20 (41%) remote patients; chi-squared = 7.05, degrees of freedom = 130, p < 0.01).Several recurring barriers were identified. This study has therefore demonstrated a significant health inequality between the treatment of STEMI in remote locations compared to central locations. Potential barriers identified include staffing availability and training, public awareness and inter-hospital communication. This suggests that there remain significant opportunities to improve STEMI care for people living in the north of Scotland

Alcohol Availability and Violence among Inner‐City Adolescents: A Multi‐Level Analysis of the Role of Alcohol Outlet Density

Researchers recognize that the connection between alcohol and peer violence may relate to community level ecological factors, such as the location of businesses that sell alcohol. Building on previous research among adults, this study examines the relationship between alcohol outlet density and violent behaviors among adolescents, taking into account demographic characteristics, individual alcohol use, and neighborhood level socioeconomic indicators. Data drawn from a diverse Emergency Department based sample of 1,050 urban adolescents, combined with tract level data from the state liquor control commission and U.S. Census, were analyzed. Results of multivariate multi‐level regression analysis indicate that alcohol outlet density is significantly related to adolescents' violent behaviors, controlling for demographic characteristics and individual alcohol use. Census tract level socioeconomic indicators were not significantly associated with youth violence. Findings suggest that alcohol outlet density regulation should be considered as part of broader violence prevention strategies for urban adolescents.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/117032/1/ajcp9353.pd

Three-month Follow-up of Brief Computerized and Therapist Interventions for Alcohol and Violence Among Teens

Alcohol use and violent behaviors are well documented among adolescents and have enormous effects on morbidity and mortality. The authors hypothesized that universal computer screening of teens in an inner-city emergency department (ED), followed by a brief intervention (BI), would be 1) feasible (as measured by participation and completion of BI during the ED visit) and well received by teens (as measured by posttest process measures of intervention acceptability) and 2) effective at changing known precursors to behavior change such as attitudes, self-efficacy, and readiness to change alcohol use and violence.Adolescent patients (ages 14–18 years) at an urban ED were approached to complete a computerized survey. The survey was conducted daily from 12 noon to 11  pm from September 2006 through November 2008. Adolescents reporting both alcohol use and violence in the past year were randomized to a control group or a 35-minute BI delivered by a computer or therapist as part of the SafERteens study. Validated measures were administered, including demographics, alcohol use, attitudes toward alcohol and violence, self-efficacy for alcohol and violence, readiness to change alcohol and violence, and process questions, including likeability of intervention.A total of 2,423 adolescents were screened. Thirteen percent of those approached refused. The population was 45% male, 58% African American, and 6.2% Hispanic. Of those screened, 637 adolescents (26%) screened positive; 533 were randomized to participate, and 515 completed the BI prior to discharge. The BIs were well received by the adolescents overall; 97% of those randomized to a BI self-reported that they found one intervention section “very helpful.” At posttest, significant reductions in positive attitudes for alcohol use and violence and significant increases in self-efficacy related to alcohol/violence were found for both therapist and computer interventions. At 3-month follow-up there was 81% retention, and generalized estimating equations (GEE) analysis showed that participants in both interventions had significant reductions in positive attitudes for alcohol use (therapist p = 0.002, computer p = 0.0001) and violence (therapist p = 0.012, computer p = 0.007) and significant increases in self-efficacy related to violence (therapist p = 0.0.04, computer p = 0.002); alcohol self-efficacy improved in the therapist BI condition only (therapist p = 0.050, computer p = 0.083). Readiness to change was not significantly improved.This initial evaluation of the SafERteens study shows that universal computerized screening and BI for multiple risk behaviors among adolescents is feasible, well received, and effective at altering attitudes and self-efficacy. Future evaluations of the SafERteens study will evaluate the interventions’ effects on behavioral change (alcohol use and violence) over the year following the ED visit.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/78665/1/j.1553-2712.2009.00513.x.pd

Dating Violence: Outcomes Following a Brief Motivational Interviewing Intervention Among At‐risk Adolescents in an Urban Emergency Department

Objectives A recent study demonstrated the efficacy of the SafERteens intervention in reducing peer violence among adolescents presenting to the emergency department (ED). The objective of this study was to determine the efficacy of this ED‐based brief intervention (BI) on dating violence 1 year following the ED visit among the subsample of adolescents in the original randomized controlled trial reporting past‐year dating violence. Methods Patients (aged 14 to 18 years) at an ED were eligible for inclusion if they had past‐year violence and alcohol use. Participants were randomized to one of three conditions (BI delivered by a computer [CBI], BI delivered by a therapist and a computer (T+CBI), or control) and completed follow‐ups at 3, 6, and 12 months. In addition to content on alcohol misuse and peer violence, adolescents reporting dating violence received a tailored module on dating violence. The outcome of interest was frequency of moderate and severe dating violence victimization and aggression (baseline and 3, 6, and 12 months after ED visit). Results Among eligible adolescents, 55% ( n  = 397) reported dating violence and were included in these analyses. Compared to the control group (who received a resource brochure only), participants in the CBI showed reductions in moderate dating victimization at 3 months (inter‐rater reliability [IRR] = 0.71; 95% confidence interval [CI] = 0.51 to 0.99; p < 0.05) and 6 months (IRR = 0.56; 95% CI = 0.38 to 0.83; p < 0.01). Models examining interaction effects were significant for the CBI on moderate dating victimization at 3 months (IRR = 0.81; 95% CI = 0.67 to 0.98; p < 0.05) and 6 months (IRR = 0.81; 95% CI = 0.66 to 0.99; p < 0.05). Significant interaction effects were found for the T+CBI on moderate dating violence victimization at 6 months (IRR = 0.81; 95% CI = 0.69 to 0.96; p < 0.01) and 12 months (IRR = 0.76; 95% CI = 0.63 to 0.90; p < 0.001) and severe dating violence victimization at 3 months (IRR = 0.76; 95% CI = 0.59 to 0.96; p < 0.05). Conclusions ED‐based BIs tailored to address multiple risk behaviors (i.e., peer violence, alcohol use, and dating violence) show promise for reducing moderate and severe dating victimization for up to 1 year following an ED visit. Resumen La Violencia de Pareja: Resultados tras una Intervención mediante una Entrevista Breve Motivacional entre los Adolescentes en Riesgo en un Servicio de Urgencias Urbano Objetivos Un estudio reciente demostró la eficacia de la intervención SafERteens en reducir la violencia entre los adolescentes que acuden al servicio de urgencias (SU). El objetivo de este estudio fue determinar la eficacia de esta intervención breve (IB) en los SU en la violencia de pareja al año tras la visita al SU en una muestra de adolescentes del ensayo clínico original controlado y aleatorizado que documentó la violencia de pareja del pasado año. Metodología Se incluyeron los pacientes entre 14 y 18 años de edad del SU que tenían antecedentes de violencia o consumo de alcohol en el pasado año. Los participantes fueron aleatorizados a una de las tres situaciones: IB realizada por un ordenador (IBO), IB realizada por un terapeuta y un ordenador (IBO + T), o control; y completaron 3, 6, y 12 meses de seguimiento. Además de contener abuso de alcohol y violencia entre iguales, los adolescentes que documentaron la violencia de pareja recibieron un módulo adaptado en violencia de pareja. El resultado de interés fue la frecuencia de violencia de pareja moderada o grave como víctima y agresor (basal, 3, 6 y 12 meses tras la visita). Resultados Entre los adolescentes elegibles, el 55% (n=397) documentó datos de violencia de pareja y fueron incluidos en estos análisis. En comparación con el grupo control (que recibieron sólo el recurso de un folleto informativo), los participantes en la IBO mostraron una reducción en la violencia de pareja moderada como víctima a los 3 meses (concordancia entre evaluadores [K] 0,71; IC 95% = 0,51 a 0,99; p < 0,05) y a los 6 meses (K 0,56; IC 95%= 0,38 a 0,83; p < 0,01); los modelos que examinaron los efectos de interacción fueron significativos para la IBO en la violencia de pareja moderada como víctima a los 3 meses (K 0,81; IC 95% = 0,67 a 0,98; p < 0,05) y a los 6 meses (K 0,81; IC 95% = 0,66 a 0,99; p < 0,05). Se hallaron efectos de interacción significativos para la IBO+T en la violencia de pareja moderada como víctima a los 6 meses (K 0,81; IC 95% = 0,69 a 0,96; p < 0,01) y a los 12 meses (K 0,76; IC 95% = 0,63 a 0,90; p < 0,001), y en la violencia de pareja grave como víctima a los 3 meses (K 0.76; IC 95% = 0,59 a 0,96; p < 0,05). Conclusiones Las IB en el SU adaptadas para valorar múltiples comportamientos de riesgo (ej: violencia entre iguales, consumo de alcohol y violencia de pareja) son prometedores para reducir la violencia de pareja moderada y grave como víctima hasta un año tras la visita al SU.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/98214/1/acem12151.pd

The desolation of Smaug : the human-driven decline of the Sungazer lizard (Smaug giganteus)

The Sungazer (Smaug giganteus) is a threatened lizard species endemic to the Highveld grasslands of South Africa. The species faces risks from habitat loss and fragmentation, and illegal harvesting for traditional medicine and the pet trade. Despite these threats, the current conservation status of the species was poorly validated. We visited 79 Sungazer populations recorded in 1978 to assess population change since the initial surveys, and surveyed an additional 164 sites to better define the distribution and estimate the current population size. We interrogated all known historical trade data of the species. One-third of Sungazer populations have been extirpated over the past 37 years. The distribution includes two allopatric populations, with the smaller Mpumalanga population experiencing a significantly higher decline. The species has an extent of occurrence (EOO) of 34 500 km2, and an area of occupancy (AOO) of 1149 km2. The interpreted distribution is 17 978 km2, and just under 60% remains untransformed grassland. We estimate a population size of 677 000 mature individuals, down 48% from the estimated historical population, prior to commercial agricultural development. A total of 1194 live Sungazers were exported under permit from South Africa between 1985 and 2014, with a significant increase in numbers exported over the last decade. Without any evidence of captive breeding, we believe that these animals are all wild-caught. Based on the AOO, level of decline, fragmentation within the distribution and suspected level of exploitation, we recommend classification of the species as Vulnerable under IUCN Red List Criteria A2acd and B2ab(ii–v). The establishment of a protected area network, genetic research and further investigations into the pet and traditional medicine trades are urgently needed.The Rufford Foundation (grant number 10843-1), SANBI’s Threatened Species Programme, National Research Foundation, Endangered Wildlife Trust, University of the Witwatersrand, The Alexander Herp Lab and Tshwane University of Technology provided funding, equipment and vehicles to S.P. for this project.http://www.elsevier.de/jnc2018-04-30Genetic
