The Effect of Occupational Therapy Play-based Interventions on Cooperative Behavior in Elementary School Aged Children with Autism Spectrum Disorder

The purpose of this study was to explore the perceptions of occupational therapy practitioners regarding the effect play-based interventions have on cooperative behaviors in elementary school aged children with autism spectrum disorder (ASD). While occupational therapy practitioners use a variety of interventions involving play to enhance skills related to social, self-regulation and communication, the concept of how play affects cooperative behavior, specifically in children with ASD, has not been readily identified. This qualitative research project utilized an anonymous survey to collect the perceptions of occupational therapists (OT) and certified occupational therapy assistants (COTA). The intent of the survey was to gain the insights of these practitioners as to the kinds of play-based interventions (sensory integration, modeling, behavioral and so forth) that are being employed with elementary school aged children and how those interventions impact cooperative behaviors. Evidenced based research is vital to developing OT treatment interventions that support the philosophy and mission of the American Occupational Therapy Organization (AOTA). It is also critical that practitioners have data, backed by research to use in practice. Based on this, more research is required to determine the role of OT in addressing cooperative play behavior in children with ASD

Detection of respiratory viruses and bacteria in children using a twenty-two target reverse-transcription real-time PCR (RT-qPCR) panel

Background: Rapid detection of the wide range of viruses and bacteria that cause respiratory infection in children is important for patient care and antibiotic stewardship. We therefore designed and evaluated a ready-to-use 22 target respiratory infection reverse-transcription real-time polymerase chain reaction (RT-qPCR) panel to determine if this would improve detection of these agents at our pediatric hospital. Methods: RT-qPCR assays for twenty-two target organisms were dried-down in individual wells of 96 well plates and saved at room temperature. Targets included 18 respiratory viruses and 4 bacteria. After automated nucleic acid extraction of nasopharyngeal aspirate (NPA) samples, rapid qPCR was performed. RT-qPCR results were compared with those obtained by the testing methods used at our hospital laboratories. Results: One hundred fifty-nine pediatric NPA samples were tested with the RT-qPCR panel. One or more respiratory pathogens were detected in 132/159 (83%) samples. This was significantly higher than the detection rate of standard methods (94/159, 59%) (P\u3c0.001). This difference was mainly due to improved RT-qPCR detection of rhinoviruses, parainfluenza viruses, bocavirus, and coronaviruses. The panel internal control assay performance remained stable at room temperature storage over a two-month testing period. Conclusion: The RT-qPCR panel was able to identify pathogens in a high proportion of respiratory samples. The panel detected more positive specimens than the methods in use at our hospital. The pre-made panel format was easy to use and rapid, with results available in approximately 90 minutes. We now plan to determine if use of this panel improves patient care and antibiotic stewardship

Exploring the effects of migration on smallholder farm households in Kenya and Burkina Faso

This brief brings together insights from a cross-country comparative study exploring the effects of rural outmigration on smallholder farm households in Eastern Kenya and the Central Plateau of Burkina Faso. It sheds light on the context-dependent nature of migration and how different types of migration can have different effects on gendered labour relations and household capacities to invest in farming and manage the farm

Land restoration amid male outmigration: The cases of Burkina Faso and Kenya

Within the global literature on ecological restoration, a subset of literature examines the relationship between smallholder land restoration and rural outmigration. However, intrahousehold dynamics surrounding the outmigration of one or more household members and the capacity of the household to undertake land restoration activities are often overlooked. With analyses rooted in Burkina Faso and Kenya, we explore the relationships between restoration, household labor, and rural outmigration, which is a prominent livelihood strategy in the two contexts. Our case studies draw on data from interviews, focus group discussions, and small-n household surveys in Burkina Faso and Kenya. Our analysis substantiates the need to consider migration in understanding and promoting smallholder land restoration. Our multi-sited approach further reveals that the contextually-specific characteristics of the migration event (i.e., type of migration [permanent or temporary], position of the migrant within the household, timing and duration of migration) play an important role in shaping restoration and gender outcomes. As male heads of households or their sons outmigrate periodically in Kenya compared to young men leaving seasonally in Burkina Faso, the impacts of migration on intrahousehold gender relations are more transformative in the Kenyan case study, with women garnering greater decision-making power on the family farm and in land restoration activities, whereas entrenched gender norms in the Burkina Faso case remain unchallenged by migration

Worldwide variations in artificial skyglow

Despite constituting a widespread and significant environmental change, understanding of artificial nighttime skyglow is extremely limited. Until now, published monitoring studies have been local or regional in scope, and typically of short duration. In this first major international compilation of monitoring data we answer several key questions about skyglow properties. Skyglow is observed to vary over four orders of magnitude, a range hundreds of times larger than was the case before artificial light. Nearly all of the study sites were polluted by artificial light. A non-linear relationship is observed between the sky brightness on clear and overcast nights, with a change in behavior near the rural to urban landuse transition. Overcast skies ranged from a third darker to almost 18 times brighter than clear. Clear sky radiances estimated by the World Atlas of Artificial Night Sky Brightness were found to be overestimated by ~25%; our dataset will play an important role in the calibration and ground truthing of future skyglow models. Most of the brightly lit sites darkened as the night progressed, typically by ~5% per hour. The great variation in skyglow radiance observed from site-to-site and with changing meteorological conditions underlines the need for a long-term international monitoring program

Differential Experiences of Climate Change: Local Knowledge and Perspectives of Severe Flooding in the Peruvian Amazon

In the context of rapid climate change, the frequency and magnitude of environmental hazards in Amazonia are continually increasing. This study seeks to understand the lived realities of environmental hazards in the Peruvian Amazon, and in particular flooding, and how experiences are shaped by differential positionalities. The study draws upon data from the Peruvian Amazon Rural Livelihoods and Poverty Project community survey (n=919) and household survey (n=3,941), as well as interview (n=24) and survey (n=25) data collected during fieldwork in Éxito, a riverine village in the Department of Ucayali, Peru. The research findings indicate that flooding experience is highly determined by intersecting lines of difference at the individual, household and village levels; that fishing occupies several related yet contested roles within the village; and that given the positive and negative implications identified of four key flood types, we need to reconsider how we define environmental hazard in the Amazonian context.M.A

Gendered effects of migration on social organization and smallholder production in Oubritenga Province, Burkina Faso

Shifting and intensifying migration flows are causing profound changes in household structures, livelihood portfolios, and rural landscapes worldwide. Yet, migration trends, including who migrates within the household, whether migration is permanent or temporary, and the relationship the migrant maintains (or not) with the household, have strong geographic particularities. In certain regions of sub-Saharan African, outmigration dominated by able-bodied men from their rural homesteads is causing a redistribution and redefinition of responsibilities, with women, children, and elders who remain on the farm negotiating ways to adjust to changing household demographics. In our study, we aim to understand migration trends and their impacts on the organization of farming households and their production systems in Oubritenga Province, in the Central Plateau of Burkina Faso. To do so, we draw on case study data acquired using mixed-methods in 12 villages in Oubritenga Province. We analyze how rural outmigration affects gendered knowledge and decision-making, labour organization and availability, investments in agricultural production systems, and future aspirations for household members who remain on the farm. We find that, in our study site, migration is highly economically-motivated, and underpinned by environmental and socio-cultural push factors. A shift toward temporary migration is shaping seasonal labour availability on the family farm, and although outmigration is overwhelmingly undertaken by young men, we do not find that a ‘feminization of agriculture’ is occurring. Instead, migrating and non-migrating men maintain most influence in decision-making, and temporary migrants contribute labour to household agriculture when they return to their farms during the wet season. We argue that the high rates of male outmigration in this context do not imply a fracture from agriculture nor a ‘feminization of agriculture’. Instead, outmigration offers potential for complementarity with and indeed new investments in the family farm, while deeply entrenched gender norms and cultural expectations raise questions about the sociocultural and intra-household outcomes of diversifying livelihoods through migration

Agroecology in Canada: Towards an Integration of Agroecological Practice, Movement, and Science

This article surveys the current state of agroecology in Canada, giving particular attention to agroecological practices, the related social movements, and the achievements of agroecological science. In each of these realms, we find that agroecology emerges as a response to the various social and ecological problems associated with the prevailing industrial model of agricultural production that has long been promoted in the country under settler colonialism. Although the prevalence and prominence of agroecology is growing in Canada, its presence is still small and the support for its development is limited. We provide recommendations to achieve a more meaningful integration of agroecology in Canadian food policy and practice.Land and Food Systems, Faculty ofNon UBCReviewedFacult
