An evaluation of two interventions on the phonetic repertoire of children with multiple disabilities

Children who have multiple disabilities often have complex communicational needs (Crickmay 1966; Orelove & Sobsey, 1996; Van Riper & Erickson, 1996; Workinger 2005). To augment or supplement these children’s communication skills some form of alternative and augmentative communication (AAC) may be provided (Beukleman & Mirenda, 2005; Downing, 1996; Orelove & Sobsey, 1996; Stephenson & Dowrick, 2005). However it has been found that parents fear AAC will prevent focus on verbal output which is the preferred way of communication (Allaire et al 1991; Beukelman & Mirenda, 2005; Schlosser, 2003; Stephenson & Dowrick, 2005). This study investigated the impact of a combined therapy approach on the phonetic repertoire of children with multiple disabilities. In addition, changes in communication intent were also explored. Each child received intervention across four, 20-30 minute sessions per week for six weeks. Results show that all of the children made improvements, however not all changes were significant. Clinical implications of the study include the notion that working on traditional therapy techniques can improve the speech and language of children who have multiple disabilities and there is a need to look further at traditional therapies and incorporate AAC into thes

Survivors of female perpetrated sexual abuse and their experiences of disclosure

Overview Female Perpetrated Sexual Abuse (FPSA) remains a largely under-studied and poorly understood phenomenon, despite its growing prevalence. Traditional gender constructions in relation to victimisation and perpetration as ‘gendered’, may be stifling its recognition, and the recognition of those affected. Survivor’s perspectives on disclosure are crucial, given its known under-reporting, and how many people feel silenced. As research on FPSA is in its relative infancy, understanding the process of disclosing is particularly important in influencing professional and social change, and progression. Method Fourteen participants of equal gender distribution, who self identified as having been sexually abused in childhood by a female, were recruited online. The study was advertised via online survivor communities, survivor charities and forums supporting survivors. Participants were directed to a website designed by the Researcher outlining the study in its entirety. Participants then offered their consent to participation and contacted the researcher via the website. Telephone interviews were arranged and conducted with participants meeting eligibility, using a qualitative semi-structured interview protocol. Interviews were transcribed and systematically analysed using a qualitative methodology applying an Inductive Thematic Analysis approach (Braun & Clarke, 2006). Results Four super-ordinate themes relating to participants disclosing sexual abuse by a female were discussed, with one being a central and over-arching theme ‘Perceptions of Gender and Disclosure’, which influenced the three further themes; Perceptions of Gender and Disclosure; consisting of ‘social attitudes’, ‘gender roles’, ‘barrier to recognition’ and ‘barrier to disclosure’ o Decisions to Disclose; consisting of ‘relationship with the perpetrator’, ‘making sense of the experience’, effects of abuse’ and ‘readiness’ o Process of Disclosure; consisting of ‘experiences of services’, ‘contexts of disclosing’ and ‘nature of disclosure’ o Experiences of Disclosure; consisting of ‘perceived professional responses’ and ‘impact of perceived professional responses’. Conclusions Constructions of gender and narrow views of ‘perpetration’ and ‘victimisation’ appear to be stifling personal, professional and social recognition of FPSA. This lack of awareness and perceived cultural denial may be silencing survivors, and restricting their ability to disclose and process their experiences. The impact of gender appears to be two-fold and future research would benefit from exploring disclosure of FPSA for males and females exclusively, as their experiences and needs may greatly differ. The value of involving survivors in educating professionals and in widening awareness is discussed

Seasonal variation in serum metabolites of northern European dogs

Background Metabolic profiling identifies seasonal variance of serum metabolites in humans. Despite the presence of seasonal disease patterns, no studies have assessed whether serum metabolites vary seasonally in dogs. Hypothesis There is seasonal variation in the serum metabolite profiles of healthy dogs. Animals Eighteen healthy, client-owned dogs. Methods A prospective cohort study. Serum metabolomic profiles were assessed monthly in 18 healthy dogs over a 12-month period. Metabolic profiling was conducted using a canine-specific proton nuclear magnetic resonance spectroscopy platform, and the effects of seasonality were studied for 98 metabolites using a cosinor model. Seasonal component was calculated, which describes the seasonal variation of each metabolite. Results We found no evidence of seasonal variation in 93 of 98 metabolites. Six metabolites had statistically significant seasonal variance, including cholesterol (mean 249 mg/dL [6.47 mmol/L] with a seasonal component amplitude of 9 mg/dL [0.23 mmol/L]; 95% confidence interval [CI] 6-13 mg/dL [0.14-0.33 mmol/L], P < .008), with a peak concentration of 264 mg/dL (6.83 mmol/L) in June and trough concentration of 236 mg/dL (6.12 mmol/L) in December. In contrast, there was a significantly lower concentration of lactate (mean 20 mg/dL [2.27 mmol/L] with a seasonal component amplitude of 4 mg/dL [0.42 mmol/L]; 95% CI 2-6 mg/dL [0.22-0.62 mmol/L], P < .001) during the summer months compared to the winter months, with a peak concentration of 26 mg/dL (2.9 mmol/L) in February and trough concentration of 14 mg/dL (1.57 mmol/L) in July. Conclusions and Clinical Importance We found no clear evidence that seasonal reference ranges need to be established for serum metabolites of dogs.Peer reviewe

Species-Specific Effects of Passive Warming in an Antarctic Moss System

Polar systems are experiencing rapid climate change and the high sensitivity of these Arctic and Antarctic ecosystems make them especially vulnerable to accelerated ecological transformation. In Antarctica, warming results in a mosaic of ice-free terrestrial habitats dominated by a diverse assemblage of cryptogamic plants (i.e. mosses and lichens). Although these plants provide key habitat for a wide array of microorganisms and invertebrates, we have little understanding of the interaction between trophic levels in this terrestrial ecosystem and whether there are functional effects of plant species on higher trophic levels that may alter with warming. Here, we used open top chambers on Fildes Peninsula, King George Island, Antarctica, to examine the effects of passive warming and moss species on the abiotic environment and ultimately on higher trophic levels. For the dominant mosses, Polytrichastrum alpinum and Sanionia georgicouncinata, we found species-specific effects on the abiotic environment, including moss canopy temperature and soil moisture. In addition, we found distinct shifts in sexual expression in P. alpinum plants under warming compared to mosses without warming, and invertebrate communities in this moss species were strongly correlated with plant reproduction. Mosses under warming had substantially larger total invertebrate communities, and some invertebrate taxa were influenced differentially by moss species. However, warmed moss plants showed lower fungal biomass than control moss plants, and fungal biomass differed between moss species. Our results indicate that continued warming may impact the reproductive output of Antarctic moss species, potentially altering terrestrial ecosystems dynamics from the bottom up. Understanding these effects requires clarifying the foundational, mechanistic role that individual plant species play in mediating complex interactions in Antarctica\u27s terrestrial food webs

Female-perpetrated sexual abuse: a review of victim and professional perspectives

Professional attitudes towards female-perpetrated sexual abuse (FPSA) reportedly reflect he gender-role expectations found in broader society, which cast males almost exclusively as sexual aggressors or willing sexual recipients, females as sexually non-coercive or victims and male-perpetrated sexual abuse as particularly significant or injurious. Such views, however, appear to stand in contrast to the perspectives of individuals who have experienced FPSA. This paper details a systematic review of peer-reviewed quantitative and qualitative literature examining these different (professional and victim) perspectives. Although the methodological shortcomings of primary papers limit the conclusions that can be drawn, the findings suggest that victim and professional perspectives of FPSA remain discrepant; professionals generally considered FPSA as less serious, less harmful and less deserving of investigation than male-perpetrated abuse; while victims of FPSA felt their experiences influenced significantly their psychological wellbeing and abilities to form and maintain interpersonal relationships. These findings are discussed in relation to professional practice and suggestions for future research

Protected areas as social-ecological systems: perspectives from resilience and social-ecological systems theory

Conservation biology and applied ecology increasingly recognize that natural resource management is both an outcome and a driver of social, economic, and ecological dynamics. Protected areas offer a fundamental approach to conserving ecosystems, but they are also social-ecological systems whose ecological management and sustainability are heavily influenced by people. This editorial, and the papers in the invited feature that it introduces, discuss three emerging themes in social-ecological systems approaches to understanding protected areas: (1) the resilience and sustainability of protected areas, including analyses of their internal dynamics, their effectiveness, and the resilience of the landscapes within which they occur; (2) the relevance of spatial context and scale for protected areas, including such factors as geographic connectivity, context, exchanges between protected areas and their surrounding landscapes, and scale dependency in the provision of ecosystem services; and (3) efforts to reframe what protected areas are and how they both define and are defined by the relationships of people and nature. These emerging themes have the potential to transform management and policy approaches for protected areas and have important implications for conservation, in both theory and practice

Predicting the Current and Future Potential Distributions of Lymphatic Filariasis in Africa Using Maximum Entropy Ecological Niche Modelling

Modelling the spatial distributions of human parasite species is crucial to understanding the environmental determinants of infection as well as for guiding the planning of control programmes. Here, we use ecological niche modelling to map the current potential distribution of the macroparasitic disease, lymphatic filariasis (LF), in Africa, and to estimate how future changes in climate and population could affect its spread and burden across the continent. We used 508 community-specific infection presence data collated from the published literature in conjunction with five predictive environmental/climatic and demographic variables, and a maximum entropy niche modelling method to construct the first ecological niche maps describing potential distribution and burden of LF in Africa. We also ran the best-fit model against climate projections made by the HADCM3 and CCCMA models for 2050 under A2a and B2a scenarios to simulate the likely distribution of LF under future climate and population changes. We predict a broad geographic distribution of LF in Africa extending from the west to the east across the middle region of the continent, with high probabilities of occurrence in the Western Africa compared to large areas of medium probability interspersed with smaller areas of high probability in Central and Eastern Africa and in Madagascar. We uncovered complex relationships between predictor ecological niche variables and the probability of LF occurrence. We show for the first time that predicted climate change and population growth will expand both the range and risk of LF infection (and ultimately disease) in an endemic region. We estimate that populations at risk to LF may range from 543 and 804 million currently, and that this could rise to between 1.65 to 1.86 billion in the future depending on the climate scenario used and thresholds applied to signify infection presence
