Australian occupational therapists' use of an online evidence-based practice database (OTseeker)

INTRODUCTION: Online databases can support the implementation of evidence-based practice by providing easy access to research. OTseeker (http://www.otseeker.com), an electronic evidence database, was introduced in 2003 to assist occupational therapists to locate and interpret research. OBJECTIVES: This study explored Australian occupational therapists' use and perceptions of OTseeker and its impact on their knowledge and practice. METHODS: A postal survey questionnaire was distributed to two samples: (i) a proportionate random sample of 400 occupational therapists from all states and territories of Australia, and (ii) a random sample of occupational therapists working in 95 facilities in two Australian states (Queensland and New South Wales). RESULTS: The questionnaire was completed by 213 participants. While most participants (85.9%) had heard of OTseeker, only 103 (56.6%) had accessed it, with lack of time being the main reason for non-use. Of the 103 participants who had accessed OTseeker, 68.9% had done so infrequently, 63.1% agreed that it had increased their knowledge and 13.6% had changed their practice after accessing information on OTseeker. CONCLUSION: Despite OTseeker being developed to provide occupational therapists with easy access to research, lack of time was the main reason why over half of the participants in this study had not accessed it. This exploratory research suggests, however, that there is potential for the database to influence occupational therapists' knowledge and practice about treatment efficacy through access to the research literature.     

The making of Mark Rothko's Harvard Murals

Mark Rothko's Harvard Murals are a series of paintings on canvas commissioned by Harvard University and created in the early 1960s. The present study investigates Rothko's creative process, materials, and technique with ultraviolet and infrared imaging, analytical chemistry, cross-sectional analysis, and comparisons with the literature. Infrared and Raman spectroscopy imaging of cross sections help with the chemical mapping of the paint stratifications. A comparison of paper studies, studies on canvas, and the final five works installed give a detailed insight into Rothko's editing process. The intimate relationship between works on paper and canvas is traced by uncovering a back and forth between the two media, and the mixing of dry pigment with binder is a common theme for works on both supports. Motif developments, changes, and distinct painting campaigns become apparent with ultraviolet induced visible fluorescence imaging and infrared reflected infrared digital photography. Color measurements and microfading experiments give insight into the stability and light sensitivity of the materials used by Rothko in the Harvard Murals.     

Counselling the Gifted and Talented in France: Minimizing Gift and Maximizing Talent

After a presentation of the French school system, we describe how the three principal practices—acceleration, enrichment, and special classes—for the education of the gifted are functioning in France. Then, we deal with the counselling of the gifted through 1) the presentation of the professional involved in these tasks, 2) the role played by the parent associations of gifted children, and 3) the identification practices. For the talented, there are many practices, from primary education onwards, which allow schooling to be reconciled with sports studies or artistic tuition. The concept of “dual project” is introduced: the need for sportsmen/women to elaborate their career plan at the same time as their sporting project. The conclusion stresses that in France, measures for the gifted are not clearly laid out; whereas, provisions benefiting from clear and explicit information have been made for the talented and are encouraged by various institutions.     

Semi-analytical Monte Carlo simulation of laser-induced fluorescence propagation in an optically participating spray

A semi-analytical Monte Carlo (SMC) simulation was developed to simulate the propagation of laser-induced fluo- rescence (LIF) in an optically participating spray, which simultaneously exhibits spectrally dependent emission, anisotropic scattering, absorption, and re-emission. The SMC simulation is described and then applied to an experimental configuration of a cloud of polydisperse droplets composed of water and sulforhodamine B dye. In the SMC simulation, the collected LIF flux on the remote receptor element is calculated as the global contribution from the emissive source, single, twice, … and nth collision events in any sequence. The effects on the fluorescence photons propagation of spray parameters like the dye concentration, droplets concentration, and droplets size are examined. Three spectral bands representing different optical properties are chosen to analyze the interference of absorption, scattering and re-emission on the detected LIF flux. The obtained spectral LIF flux distribution on the receptor demonstrates a “red shift” phenomenon.     

“I Am Not a Francophone”: Identity Choices and Discourses of Youth Associating With a Powerful Minority

Taking a broad interest in the linguistic, educational, and identity issues relevant to young people, this article examines the experiences and discourses of linguistic minority youth in the French-dominant context of Québec City. Our analysis is based on qualitative interviews conducted with 10 young people who speak a language other than French at home and who chose to study in English at the postsecondary level. Beyond exploring the local impact of language policies, we focus on the identity choices these youth make in positioning themselves and the discourses that they appropriate in describing their sociolinguistic context. Findings suggest that tensions between linguistic groups in Québec are perpetuated through discourses that distance one group from another, including discourses of closed-mindedness and superiority. What the students in our study appear to be doing is rejecting a minority identity by invoking national and international scales through their discourses, scales in which English is dominant.     

The development of epiphonological and metaphonological processing at the start of learning to read: A longitudinal study

The processes involved in the processing of phonological information (awareness and phonological recoding) now occupy a key position in the study of the acquisition of reading. The research performed in the field of learning to read have helped support the idea that the learning of writing is based on the ability to develop a phonological knowledge of the formal properties of the spoken language (Mattingly, 1972). Many studies have therefore been devoted to the relations between the learning of reading and phonological skills, that is to say the ability to perform a phonological analysis of spoken language. The present research concerns the development of the phonological skills both before and during the teaching of reading through the longitudinal study of children in their final year of nursery school (NS) and in first grade (FG).     

Comparative study of the cognitive sequelae of school-aged victims of Shaken Baby Syndrome

OBJECTIVE: Shaken Baby Syndrome (SBS) is now recognized as being the main cause of severe traumatic brain injury in infancy. However, our understanding of the impact of this type of abuse on child development remains sketchy. The main objective of the current study was therefore to shed light on the cognitive dysfunctions that are particular to SBS victims once they are school-aged. METHOD: A clinical group was formed of 11 children diagnosed with SBS who had been admitted between 1988 and 1999 to a tertiary pediatric hospital in Quebec, Canada. The children were matched for age, gender, socio-economic status, and family composition to 11 healthy Quebec children, who made up the control group. A battery of composite tests was developed to assess the children's main cognitive functions and was administered individually to the 22 children. A univariate t-test was used to compare the performances of the two groups. RESULTS: The mean age of the children in the clinical and control groups at the time of the assessment was 87.64 months and 90.18 months, respectively. Pairing and birth data were equivalent for both groups. Significant weaknesses were noted in the clinical group for intelligence quotient (IQ), working memory, mental organization, alternation, and inhibition. These deficits seemed to have a greater impact on the verbal sphere of the children's mental functioning. CONCLUSION: Primary results point to the anterior cerebral regions of the brain as the principal site of dysfunctions that persist years post-trauma. It is important to consider these results longitudinally, even in children apparently less extensively affected, since the frontal regions only reach maturity at the end of adolescence.
