Parent Satisfaction with Family Professional Partnerships and Services for Children with Autism Spectrum Disorder

As an increasing number of children are diagnosed with Autism Spectrum Disorders (ASD), research on the efficacy of interventions and treatments—the way these services affect the family, the child’s outcomes, and the family’s experience with their child’s services—are gaining importance. Children with ASD tend to be involved in multiple services to a higher degree than children with other disabilities, and parents of children with ASD have reported higher dissatisfaction with services than have parents of children with other developmental disabilities. To date, limited research has addressed the family’s perception of these services and how they feel service providers improve child and family outcomes. The present study employed a mixed-methods design to provide a thorough understanding of parents’ experiences of using services for their child with ASD. It was hypothesized that parents who reported lower child problem behaviors and higher levels of child prosocial behaviors would report greater satisfaction with child- and family-focused services, and that parents who reported higher levels of stress would report lower satisfaction with services and less positive appraisals of their child’s functioning. Qualitative questions were analyzed through thematic analysis and provided information on positive and negative experiences that parents had in their interactions with service providers, and how providers helped parents see their child’s strengths. Results of multiple regression analysis indicated that parent appraisals of child functional behaviors were negatively related to parent satisfaction with child- and family-focused aspects of services, such that parents who reported higher satisfaction with professional partnerships reported lower child problem behaviors and higher levels of child prosocial behaviors. In addition, hierarchical regressions indicated that parents who experienced more stressful events over their lifetime reported lower satisfaction with services and perceived higher rates of child problem behaviors, after controlling for multicollinearity between the two measures of stress. There was a negative relationship between the age of the child and parent satisfaction with professional partnerships. Qualitative analyses revealed a number of ways in which providers helped parents feel supported, including presenting an image of competence, attempting to build relationships with parents, and helping parents understand their child’s diagnosis and positive progress. Parents reported that they had negative experiences when they felt disregarded by providers, perceived that their provider lacked competency, or experienced difficulty obtaining appointments. This study contributes to the literature by considering both parent perceptions of the severity of their child’s functioning and child functional behaviors from a strengths-based approach. The importance of this mixed-methods study was to provide a forum for parents to report their experiences in a way that could meaningfully inform clinical interventions and foster best practices. Limitations and future directions for this research are also addressed

Fatty acid profiles of serum lipid fractions change minimally in sled dogs before and after short bouts of exercise

Although emerging data suggests a greater influence of gluconeogenic precursors, endurance sled dogs have long appeared to rely heavily on fatty acid oxidation for sustained energy production. However, much of the research investigating lipid utilization during exercise in sled dogs has been carried out with dogs subjected to extended bouts of endurance exercise. Less is known about changes in fatty acid composition in endurance training sled dogs subjected to short bouts of exercise, and fewer data define how fatty acid composition may change in distinct lipid fractions. As such, the study objective was to assess whether short bouts of submaximal exercise would affect fatty acid profiles of serum lipid fractions in endurance training sled dogs. Fifteen privately-owned Siberian huskies were used (8 females: 4 intact, 4 spayed; 7 males: 2 intact, 5 neutered), with an average age of 4.6 ± 2.5 years and body weight of 24.8 ± 4.2 kg. Throughout the diet acclimation and remainder of the study, all dogs were fed a dry extruded diet that met or exceeded all AAFCO nutrient recommendations. Dogs were weighed weekly and fed to maintain baseline body weight. A 12-week exercise regimen was designed to incorporate weekly increases in running distance, but weather played a role in setting the daily distance. On weeks 2, 5, and 11, an exercise challenge was implemented whereby dogs would run 4 km at 15 km/h in teams of 4. Pre- and post-exercise blood samples were taken, and gas chromatography was used to evaluate fatty acid profiles of all identified serum lipid fractions (cholesterol ester, diacylglycerol, free fatty acid, phospholipids, triglyceride). Data were analyzed using PROC MIXED of SAS, with dog as a random effect and week and sampling time point as fixed effects. Composition of oleic (18:1n9), linoleic (18:2n6), and alpha-linolenic (18:3n3) acids in the free fatty acid fraction decreased by ∼9, 10, and 60%, respectively, following exercise (P ≤ 0.05). The results presented herein suggest that aside from a degree of depletion of these 18-carbon unsaturated fatty acids, short bouts of submaximal exercise do not induce considerable changes to sled dog fatty acid profiles

ConXsense - Automated Context Classification for Context-Aware Access Control

We present ConXsense, the first framework for context-aware access control on mobile devices based on context classification. Previous context-aware access control systems often require users to laboriously specify detailed policies or they rely on pre-defined policies not adequately reflecting the true preferences of users. We present the design and implementation of a context-aware framework that uses a probabilistic approach to overcome these deficiencies. The framework utilizes context sensing and machine learning to automatically classify contexts according to their security and privacy-related properties. We apply the framework to two important smartphone-related use cases: protection against device misuse using a dynamic device lock and protection against sensory malware. We ground our analysis on a sociological survey examining the perceptions and concerns of users related to contextual smartphone security and analyze the effectiveness of our approach with real-world context data. We also demonstrate the integration of our framework with the FlaskDroid architecture for fine-grained access control enforcement on the Android platform.Comment: Recipient of the Best Paper Awar

Marine epibenthic functional diversity on Flemish Cap (north- west Atlantic)—Identifying trait responses to the environment and mapping ecosystem functions

Aim To characterize the functional diversity and selected ecological functions of marine epibenthic invertebrate communities at the ecosystem scale and to evaluate the relative contributions of environmental filtering, including bottom-contact fishing, and competitive interactions to benthic community assembly. Location Flemish Cap, an ecosystem production unit and fishing bank in the high seas of the north-west Atlantic Ocean. Methods Through the use of Hierarchical Modelling of Species Communities (HMSC), we have explored seven community response traits to the environment applied to 105 epibenthic species and evaluated the influence of such traits on the community assembly processes. Assumed bioturbation, nutrient cycling and habitat provision functions, linked to individual or a combination of biological traits, were mapped using random forest modelling. Results Functional richness within benthic communities reached an asymptote for trawl sets with roughly more than 30 species. Assemblages on top of the Flemish Cap (Peer reviewe

Upgrade of the MARI spectrometer at ISIS

The MARI direct geometry time-of-flight neutron spectrometer at ISIS has been upgraded with an $m=3$ supermirror guide and new detector electronics. This has resulted in a flux gain of ${\approx}6{\times}$ at $\lambda=1.8$ {\AA}, and improvements on discriminating electrical noise, allowing MARI to continue to deliver a high quality science program well into its fourth decade of life
