From early relationships to preacademic knowledge : a socio-cognitive developmental cascade to school readiness
This study aimed to test a four-wave sequential mediation model linking mother–child
attachment to children’s school readiness through child executive functioning (EF) and
prosociality in toddlerhood and the preschool years. Mother–child attachment security was
assessed when children (N = 255) were aged 15 months and 2 years, child EF at age 2, prosocial
behavior at age 4, and finally cognitive school readiness in kindergarten (age 6). The results
revealed three indirect pathways linking attachment to school readiness: one through EF only,
one through prosocial behavior only, and a last pathway involving both EF and prosocial
behavior serially. These findings suggest that secure attachment may equip children with both
cognitive and social skills that are instrumental to their preparedness for school
Predicting exercise motivation and exercise behavior: A moderated mediation model testing the interaction between perceived exercise variety and basic psychological needs satisfaction
Objectives Perceived variety in exercise predicts exercise behavior through autonomous motivation. However, psychological need satisfaction (viz. for competence, autonomy, and relatedness) may moderate the relationship between perceived variety in exercise and exercise behavior (through autonomous motivation). The purpose of the present study was to examine whether the satisfaction of the basic psychological needs in exercise contexts moderates the mediating role of autonomous exercise motivation in the relationship between perceived variety in exercise and exercise behavior. Design Cross-sectional. Method Adults (N = 499) completed an online questionnaire to measure the study variables. Associations were examined using structural equation modeling. Results Psychological need satisfaction moderated the positive indirect relationship between perceived exercise variety and self-reported exercise behavior (via autonomous motivation) such that perceived variety was associated with exercise behavior when psychological need satisfaction scores were lower than average. Conclusions Based on these findings, perceived exercise variety may act as a compensatory source of motivation when psychological need satisfaction is low. In addition to attempting to foster need-supportive exercise contexts, it may be particularly important for exercise promotion specialists to foster the experience of variety among individuals who have lower psychological need satisfaction

Psychometric properties of the Late-Life Function and Disability Instrument: a systematic review
Background: The choice of measure for use as a primary outcome in geriatric research is contingent upon the construct of interest and evidence for its psychometric properties. The Late-Life Function and Disability Instrument (LLFDI) has been widely used to assess functional limitations and disability in studies with older adults. The primary aim of this systematic review was to evaluate the current available evidence for the psychometric properties of the LLFDI. Methods: Published studies of any design reporting results based on administration of the original version of the LLFDI in community-dwelling older adults were identified after searches of 9 electronic databases. Data related to construct validity (convergent/divergent and known-groups validity), test-retest reliability and sensitivity to change were extracted. Effect sizes were calculated for within-group changes and summarized graphically. Results: Seventy-one studies including 17,301 older adults met inclusion criteria. Data supporting the convergent/divergent and known-groups validity for both the Function and Disability components were extracted from 30 and 18 studies, respectively. High test-retest reliability was found for the Function component, while results for the Disability component were more variable. Sensitivity to change of the LLFDI was confirmed based on findings from 25 studies. The basic lower extremity subscale and overall summary score of the Function component and limitation dimension of the Disability component were associated with the strongest relative effect sizes. Conclusions: There is extensive evidence to support the construct validity and sensitivity to change of the LLFDI among various clinical populations of community-dwelling older adults. Further work is needed on predictive validity and values for clinically important change. Findings from this review can be used to guide the selection of the most appropriate LLFDI subscale for use an outcome measure in geriatric research and practice
Reverse evolution of armor plates in the threespine stickleback.
Faced with sudden environmental changes, animals must either adapt to novel environments or go extinct. Thus, study of the mechanisms underlying rapid adaptation is crucial not only for the understanding of natural evolutionary processes but also for the understanding of human-induced evolutionary change, which is an increasingly important problem [1-8]. In the present study, we demonstrate that the frequency of completely plated threespine stickleback fish (Gasterosteus aculeatus) has increased in an urban freshwater lake (Lake Washington, Seattle, Washington) within the last 40 years. This is a dramatic example of "reverse evolution,"[9] because the general evolutionary trajectory is toward armor-plate reduction in freshwater sticklebacks [10]. On the basis of our genetic studies and simulations, we propose that the most likely cause of reverse evolution is increased selection for the completely plated morph, which we suggest could result from higher levels of trout predation after a sudden increase in water transparency during the early 1970s. Rapid evolution was facilitated by the existence of standing allelic variation in Ectodysplasin (Eda), the gene that underlies the major plate-morph locus [11]. The Lake Washington stickleback thus provides a novel example of reverse evolution, which is probably caused by a change in allele frequency at the major plate locus in response to a changing predation regime
Challenges Related to Three Cases of Fatal Intoxication to Multiple Novel Synthetic Opioids
In the last two decades, a large increase in opioid overdose death rates has been recorded in North America. This phenomenon, related to the misuse of prescription opioids, has been dubbed an “opioids crisis”. Recent years have seen the entrance of novel synthetic opioids (NSO) on the market, compounding the fatal intoxications issue. This brings several challenges for forensic toxicology laboratories: an increased number of cases, a large number of novel structurally similar compounds to include in screening analytical methods, the low concentration of drugs in biological fluids, and the challenging interpretation in the absence of sufficient literature. Three cases of fatal intoxication highlighting those challenges are presented, complete with post-mortem concentrations in cardiac blood, femoral blood and urine. Toxicological screening and quantitative analyses were performed on the biological specimens. In the first and second cases, furanylfentanyl, U-47700 and 4-anilino-N-phenethylpiperidine (4-ANPP) were detected at similar concentrations in cardiac blood. In the third case, a total of seventeen different NSO were detected. All intoxications showed a combination of NSO and other drugs. These three cases appear to be the harbinger of an increased NSO prevalence in the province of Québec, Canada
The Future of Women\u27s Studies (Continued)
from the CALIFORNIA STATE UNIVERSITY, CHICO
Women\u27s Studies at Chico developed from courses offered by women in their different departments, gathered to form a minor degree program in spring, 1973. Two specifically women\u27s studies courses were designed at that time: a team-taught Introduction to Women\u27s Studies (draws around 80 students a semester, changes women students\u27 expectations and horizons by projecting models of achieving women) and a Senior Research Seminar designed to integrate the students\u27 major and minor. Both are taught by the Women\u27s Studies Coordinator. Student demand has led to the development of new courses whose content received a great deal of student input: Women\u27s Health, Women in the Working World, Women in Art, Minority Women and the Re-Entry Program for Mature Women. There are now 20 courses offered through the Women\u27s Studies Program. Students are designing special degrees on the B.A. and M.A. level in areas such as Women and Counseling, Psychology and Art.

Kids' Outcomes And Long-term Abilities (KOALA): protocol for a prospective, longitudinal cohort study of mild traumatic brain injury in children 6 months to 6 years of age
Introduction: Mild traumatic brain injury (mTBI) is highly prevalent, especially in children under 6 years. However, little research focuses on the consequences of mTBI early in development. The objective of the Kids' Outcomes And Long-term Abilities (KOALA) study is to document the impact of early mTBI on children's motor, cognitive, social and behavioural functioning, as well as on quality of life, stress, sleep and brain integrity. Methods and analyses KOALA is a prospective, multicentre, longitudinal cohort study of children aged 6 months to 6 years at the time of injury/recruitment. Children who sustain mTBI (n=150) or an orthopaedic injury (n=75) will be recruited from three paediatric emergency departments (PEDs), and compared with typically developing children (community controls, n=75). A comprehensive battery of prognostic and outcome measures will be collected in the PED, at 10 days, 1, 3 and 12 months postinjury. Biological measures, including measures of brain structure and function (magnetic resonance imaging, MRI), stress (hair cortisol), sleep (actigraphy) and genetics (saliva), will complement direct testing of function using developmental and neuropsychological measures and parent questionnaires. Group comparisons and predictive models will test the a priori hypotheses that, compared with children from the community or with orthopaedic injuries, children with mTBI will (1) display more postconcussive symptoms and exhibit poorer motor, cognitive, social and behavioural functioning;(2) show evidence of altered brain structure and function, poorer sleep and higher levels of stress hormones. A combination of child, injury, socioenvironmental and psychobiological factors are expected to predict behaviour and quality of life at 1, 3 and 12 months postinjury. Ethics and dissemination The KOALA study is approved by the Sainte-Justine University Hospital, McGill University Health Centre and University of Calgary Conjoint Health Research Ethics Boards. Parents of participants will provide written consent. Dissemination will occur through peer-reviewed journals and an integrated knowledge translation plan
