Knowledge translation and occupational therapy: A survey of Canadian university programs

While Canadian occupational therapy recognizes knowledge translation (KT) as essential to clinical interactions, there has been little attention paid to KT activity in education and research. The objective of this study was to identify the nature of KT activities in which Canadian occupational therapy faculty engage. An electronic survey was sent to faculty at 14 Canadian occupational therapy programs to explore the nature of KT activities, including research, education, strategies, evaluation, and barriers and facilitators. Descriptive statistics were used to analyze the data. Results show that faculty engage in a range of KT activities, with conferences and peer-reviewed publications being the most common. Faculty collaborate frequently with researchers at their institutions and favor both integrated and end-of-grant KT. Collaboration and personal interest were identified as facilitators; time and funding were seen as barriers. Understanding the profile of KT activity across universities creates opportunities for developing institutional and pan-Canadian plans to enhance KT training and capacity

The millipedes of Barrow Island, Western Australia (Diplopoda)

Six species of millipedes are recorded from Barrow Island, including three species of pin-cushion millipedes of the order Polyxenida, Lophoturus madecassus (Marquet and Condé, 1950) (Lophoproctidae), Unixenus mjoebergi (Verhoeff, 1924) (Polyxenidae) and Phryssonotus novaehollandiae (Silvestri, 1923) (Synxenidae), a single species of the order Spirobolida, Speleostrophus nesiotes Hoffman, 1994 (Trigoniulidae), and two species of the order Polydesmida, Boreohesperus dubitalis Car and Harvey, 2013 (Paradoxosomatidae) and one species of the family Haplodesmidae (genus and species indet.). Lophoturus madecassus is circum-tropical in distribution, Unixenus mjoebergi and Phryssonotus novaehollandiae are found also on mainland Australia, but the other three species are endemic to the island. Speleostrophus nesiotes is a highly modified troglobiotic species, currently listed as threatened by the Western Australian government. It is unclear at present whether the haplodesmid specimen is a troglobite

Site-selection model for optimal transplantation of eelgrass Zostera marina in the northeastern US

A site-selection model for eelgrass Zostera marina L. ecosystem restoration was developed in the northeastern US to select optimal areas for transplanting eelgrass. The site-selection model synthesizes available historic and literature-based information, reference data, and simple field measurements to identify and prioritize locations for large-scale eelgrass transplantation. Model development was based on the physical and biological characteristics associated with the most successful transplant sites in a mitigation project for the New Hampshire Port Authority. The site-selection process is divided into 3 phases: (1) the first phase uses available environmental information to formulate a preliminary transplant suitability index (PTSI) for pre-screening and eliminating unsuitable sites; (2) the second phase involves field measurements of light availability and bioturbation as well as survival and growth of test transplants at priority sites identified by the PTSI; (3) a transplant suitability index (TSI) score is calculated for each site based on the PTSI and the results of field assessments. The TSI is a multiplicative index that eliminates sites which receive ratings of zero and gives high scores to those sites with the greatest potential for successful transplantation. We applied the TSI post hoc to the New Hampshire Port Project¹s eelgrass transplant sites, and subsequently the site-selection model was used in an eelgrass restoration project in New Bedford Harbor, Massachusetts. After 2 yr of transplanting, the New Bedford Harbor effort has resulted in success at 62% of the sites planted using the site-selection model

Aging Faces and Aging Perceivers: Young and Older Adults are Less Sensitive to Deviations from Normality in Older than in Young Adult Faces

Past studies examining the other-age effect, the phenomenon in which own-age faces are recognized more accurately than other-age faces, are limited in number and report inconsistent results. Here we examine whether the perceptual system is preferentially tuned to differences among young adult faces. In experiment 1 young (18-25 years) and older adult (63-87 years) participants were shown young and older face pairs in which one member of each pair was undistorted and the other had compressed or expanded features. Participants indicated which member of each pair was more normal and which was more expanded. Both age groups were more accurate when tested with young compared with older faces -- but only when judging normality. In experiment 2 we tested a separate group of young adults on the same two tasks but with upright and inverted face pairs to examine the differential pattern of results between the normality and discrimination tasks. Inversion impaired performance on the normality task but not the discrimination task and eliminated the young adult advantage in the normality task. Collectively, these results suggest that the face processing system is optimized for young adult faces and that abundant experience with older faces later in life does not reverse this perceptual tuning.

Representing young and older adult faces: Shared or age-specific prototypes?

Young adults recognize young adult faces more accurately than older adult faces and are more sensitive to how individual young faces deviate from a norm/prototype. Here we used an adaptation paradigm to examine whether young and older adult faces are represented by separable norms and the extent to which the coding dimensions for these two categories overlap. In Experiment 1, following adaptation to oppositely distorted young and older faces (e.g., expanded young and compressed older faces), adults’ normality judgments simultaneously shifted in opposite directions for the two face categories, providing evidence for separable norms. In Experiment 2, participants were adapted to distorted faces from a single age category (e.g., compressed young); aftereffects transferred across face age but were larger for the face age that matched adaptation. Collectively, these results provide evidence that young and older faces are processed with regard to separable norms that share some underlying coding dimensions. [ABSTRACT FROM AUTHOR

Attractiveness Judgments and Discrimination of Mommies and Grandmas: Perceptual Tuning for Young Adult Faces

Highlights •3- and 7-year-olds judged young and older face pairs: one normal and one distorted.•Attractiveness judgments (referencing a norm) were more accurate for young faces.•Performance on a match-to-sample task was also more accurate for young faces.•Our results have implications for how face space becomes optimized for young faces.•We discuss implications for domain-general vs. domain-specific development

Differential attentional allocation and subsequent recognition for young and older adult faces

Studies examining own-age recognition biases report inconsistent results and often utilize paradigms that present faces individually and in isolation. We investigated young and older adults' attention towards young and older faces during learning and whether differential attention influences recognition. Participants viewed complex scenes while their eye movements were recorded; each scene contained two young and two older faces. Half of the participants formed scene impressions and half prepared for a memory test. Participants then completed an old/new face recognition task. Both age groups looked longer at young than older faces; however, only young adults showed an own-age recognition advantage. Participants in the memory condition looked longer at faces but did not show enhanced recognition relative to the impressions condition. Overall, attention during learning did not influence recognition. Our results provide evidence for a young adult face bias in attentional allocation but suggest that longer looking does not necessarily indicate deeper encoding.This work was supported by a Discovery Accelerator Supplement Award from the Natural Sciences and Engineering Research Council of Canada grant (CJM), a Canada Foundation for Innovation grant (CJM), and a Vanier Canada Graduate Scholarship (LAS)

Category-specific face prototypes are emerging, but not yet mature, in 5-year-old children

Adults’ expertise in face recognition has been attributed to norm-based coding. Moreover, adults possess separable norms for a vari-ety of face categories (e.g., race, sex, age) that appear to enhancerecognition by reducing redundancy in the information shared byfaces and ensuring that only relevant dimensions are used toencode faces from a given category. Although 5-year-old childrenprocess own-race faces using norm-based coding, little is knownabout the organization and refinement of their face space. The cur-rent study investigated whether 5-year-olds rely on category-spe-cific norms and whether experience facilitates the development ofdissociable face prototypes. In Experiment 1, we examinedwhether Chinese 5-year-olds show race-contingent opposing after-effects and the extent to which aftereffects transfer across face raceamong Caucasian and Chinese 5-year-olds. Both participant racesshowed partial transfer of aftereffects across face race; however,there was no evidence for race-contingent opposing aftereffects.To examine whether experience facilitates the development of cat-egory-specific prototypes, we investigated whether race-contin-gent aftereffects are present among Caucasian 5-year-olds withabundant exposure to Chinese faces (Experiment 2) and thentested separate groups of 5-year-olds with two other categorieswith which they have considerable experience: sex (male/femalefaces) and age (adult/child faces) (Experiment 3). Across all threecategories, 5-year-olds showed no category-contingent opposingaftereffects. These results demonstrate that 5 years of age is a stagecharacterized by minimal separation in the norms and associated oding dimensions used for faces from different categories andsuggest that refinement of the mechanisms that underlie expertface processing occurs throughout childhood

Judging Normality and Attractiveness in Faces: Direct Evidence of a More Refined Representation for Own-Race, Young Adult Faces

Young and older adults are more sensitive to deviations from normality in young than older adult faces, suggesting that the dimensions of face space are optimized for young adult faces. Here, we extend these findings to own-race faces and provide converging evidence using an attractiveness rating task. In Experiment 1, Caucasian and Chinese adults were shown own- and other-race face pairs; one member was undistorted and the other had compressed or expanded features. Participants indicated which member of each pair was more normal (a task that requires referencing a norm) and which was more expanded (a task that simply requires discrimination). Participants showed an own-race advantage in the normality task but not the discrimination task. In Experiment 2, participants rated the facial attractiveness of own- and other-race faces (Experiment 2a) or young and older adult faces (Experiment 2b). Between-rater variability in ratings of individual faces was higher for other-race and older adult faces; reduced consensus in attractiveness judgments reflects a less refined face space. Collectively, these results provide direct evidence that the dimensions of face space are optimized for own-race and young adult faces, which may underlie face race- and age-based deficits in recognition.

Population policies and education: exploring the contradictions of neo-liberal globalisation

The world is increasingly characterised by profound income, health and social inequalities (Appadurai, 2000). In recent decades development initiatives aimed at reducing these inequalities have been situated in a context of increasing globalisation with a dominant neo-liberal economic orthodoxy. This paper argues that neo-liberal globalisation contains inherent contradictions regarding choice and uniformity. This is illustrated in this paper through an exploration of the impact of neo-liberal globalisation on population policies and programmes. The dominant neo-liberal economic ideology that has influenced development over the last few decades has often led to alternative global visions being overlooked. Many current population and development debates are characterised by polarised arguments with strongly opposing aims and views. This raises the challenge of finding alternatives situated in more middle ground that both identify and promote the socially positive elements of neo-liberalism and state intervention, but also to limit their worst excesses within the population field and more broadly. This paper concludes with a discussion outling the positive nature of middle ground and other possible alternatives
