Optimizing Partnership Impact: Prioritizing High-Quality Social-Emotional Learning In A Sports Enrichment Out-Of-School Time Program

Research demonstrates that out-of school time (OST) programs featuring physical activity positively impact students\u27 social-emotional learning (SEL) competencies, including self-regulation and collaboration skills. However, financial barriers prevent low-income students access to OST and sports opportunities. Grant-funded OST partnerships seeking to improve student well-being, emotional safety, and connection need ways to measure their value. A systems view indicates that OSTs play an interactive role within a school\u27s complex system. Guided by the Improvement Science Framework, this Dissertation-in-Practice aimed to strengthen the SEL quality of 2-4-1 TOP Self Sports, a physical literacy-informed sports enrichment OST program serving primarily elementary school students. Using an action research methodology and a mixed-methods sequential explanatory design, the study used the Forum for Youth Investment\u27s SEL PQA, a research-validated program evaluation tool measuring the quality of OST\u27s SEL practices and opportunities. The researcher collaborated with the OST, 2- 4-1 CARE, to design and implement a job-embedded curriculum-based SEL intervention at two urban-based magnet schools. The researcher analyzed pre- and post-intervention scores and transcripts from semi-structured focus groups with 2-4-1 instructors to determine the extent of the intervention\u27s impact. Post-intervention data indicate high-quality SEL in 2-4-1 TOP Self improvement in three of the four domains and two of the three focus areas. 2-4-1 instructors indicated the SEL intervention increased their intentionality to promote self-awareness and selfregulation skills. They observed student SEL growth during and beyond the sports enrichment time, suggesting the potential for 2-4-1 TOP Self to improve school climat

Language and culture in perception: a three-pronged investigation of phylogenetic, ontogenetic and cross-cultural evidence

Brown and Lenneberg (I954) and Rosch Heider (1972) were among the first to conduct psychological investigations to test the Whorfian view that language affects thought. They both asked about colour categories. The debate has continued with some research supporting a relativist (Whorfian) account (Davidoff, Davies & Roberson, I999; Borodistsky, 200I), and some supporting a universalist account (e.g., Kay & Regier, 2003; Spelke & Kinzler, 2007). The present thesis adds to the debate by taking three different approaches i.e., cross-cultural, ontogenetic and phylogenetic frames in which to carry out investigations of categorization of various perceptual continua. Categorical Perception's hallmark is the effect of mental warping of space such as has been found for phonemes (Pisani & Tash, I974) and colour (Bornstein & Monroe, I980; Bornstein & Korda, I984). With respect to colours, those that cross a category boundary seem more distant than two otherwise equally spaced colours from the same category. Warping is tested using cognitive methods such as two-alternative-forced-choice and matching-to-sample. Evidence is considered for the continua under investigation i.e. colour and animal patterns. Experiments 1 and 2 find evidence of categorical perception for human-primates and not for monkeys. Experiment 3 finds that Himba and English human adults categorize differently, particularly for colours crossing a category boundary, but also show broad similarity in solving the same matching-to-sample task as used with the monkeys (experiment I) who showed clear differences with humans. Experiment 4 and 5 tested Himba and English toddlers and found categorical perception of colour mainly for toddlers that knew their colour terms despite prior findings (Franklin et al., 2005) indicative of universal colour categories. In experiment 6, Himba and English categorical perception of animal patterns was tested for the first time, and result indicate a cross-category advantage for participants who knew the animal pattern terms. Therefore, a weak Whorfian view of linguistic relativity's role in obtaining categorical perception effects is presented. Although there is some evidence of an inherent human way of grouping drawn from results of experiment 1 and 3, results in all experiments (1,2,3,4,5, and 6) show that linguistic labels and categorical perception effects go hand-in-hand; categorization effects are not found when linguistic terms are not acquired at test and have not had a chance to affect cognition. This was true for all populations under observation in this set of studies, providing further support for effects of language and culture in perception

Categorical perception of animal patterns

As part of the more general issue of whether culture can affect perception, the present paper addresses the Whorfian question of whether the language available to describe perceptual experience can influence the experience itself. It investigated the effect of vocabulary on perceptual classification by the study of a remote culture (Himba) which possesses a poor colour vocabulary but a rich vocabulary of animal pattern terms. Thus, the present study examined Categorical Perception (CP) with a type of visual stimulus not previously used to assess the effect of labels on perceptual judgments. For the animal patterns, the Whorfian view predicted that it would only be the Himba who showed superiority for cross-category decisions as only they have the appropriate labels. The Whorfian view was upheld and confirmed previous findings that linked perceptual differences to labelling differences

Interaction of Seed Dispersal and Environmental Filtering Affects Woody Encroachment Patterns in Coastal Grassland

Encroachment of woody plants into grasslands has occurred worldwide and includes coastal ecosystems. This conversion process is mediated by seed dispersal patterns, environmental filtering, and biotic interactions. As spatiotemporally heterogeneous, harsh environments, barrier islands present a unique set of challenges for dispersal and establishment. Environmental conditions act as filters on dispersed seeds, thereby influencing encroachment and distribution patterns. Seldom have patterns of propagule dispersal been considered in the context of woody encroachment. We quantified dispersal and post‐dispersal processes of an encroaching woody population of Morella cerifera relative to directional rate of encroachment and observed distribution patterns on an Atlantic coastal barrier island with strong environmental filtering. We analyzed historic foredune elevation as a proxy for reduced interior environmental stress. The dispersal kernel was leptokurtic, a common characteristic of expanding populations, but rate of encroachment has slowed since 2005. Expansion pattern was related to foredune elevation, which limits encroachment below a threshold elevation. This difference between dispersal kernel behavior and encroachment rate is due to limited availability of suitable habitat for Morella and temporal variability in chlorides during the time of germination. Our results demonstrate that processes mediating seeds and seedling success must be accounted for to better understand establishment patterns of encroaching woody plants

More Accurate Size Contrast Judgments in the Ebbinghaus Illusion by a Remote Culture

International audienceThe Ebbinghaus (Titchener) illusion was examined in a remote culture (Himba) with no words for geometric shapes. The illusion was experienced less strongly by Himba compared with English participants, leading to more accurate size contrast judgments in the Himba. The study included two conditions of inducing stimuli. The illusion was weaker when the inducing stimuli were dissimilar (diamonds) to the target (circle) compared with when they were similar (circles). However, the illusion was weakened to the same extent in both cultures. It is argued that the more accurate size judgments of the Himba derive from their tendency to prioritize the analysis of local details in visual processing of multiple objects, and not from their impoverished naming

A Non-Stop S-Antigen Gene Mutation Is Associated With Late Onset Hereditary Retinal Degeneration in Dogs

Purpose: To identify the causative mutation of canine progressive retinal atrophy (PRA) segregating as an adult onset autosomal recessive disorder in the Basenji breed of dog. Methods: Basenji dogs were ascertained for the PRA phenotype by clinical ophthalmoscopic examination. Blood samples from six affected cases and three nonaffected controls were collected, and DNA extraction was used for a genome-wide association study using the canine HD Illumina single nucleotide polymorphism (SNP) array and PLINK. Positional candidate genes identified within the peak association signal region were evaluated. Results: The highest -Log10(P) value of 4.65 was obtained for 12 single nucleotide polymorphisms on three chromosomes. Homozygosity and linkage disequilibrium analyses favored one chromosome, CFA25, and screening of the S-antigen (SAG) gene identified a non-stop mutation (c.1216T\u3eC), which would result in the addition of 25 amino acids (p.*405Rext*25). Conclusions: Identification of this non-stop SAG mutation in dogs affected with retinal degeneration establishes this canine disease as orthologous to Oguchi disease and SAG-associated retinitis pigmentosa in humans, and offers opportunities for genetic therapeutic intervention
