Reading is typically considered a survival skill in our technology- and literacy-bound culture. Individuals who struggle with learning to read are at significantly elevated risk for a number of negative outcomes, including school failure, under- and unemployment, and special education placement. Thus, those who do not learn to read fluently will likely be a greater drain on society's resources. The authors examined the effects of a universal (school district-wide) implementation of a well-validated peer-tutoring reading intervention as a system-wide prevention measure in kindergarten through Grade 3 in a small metropolitan area in Canada. Results suggest that nearly all children demonstrated improved reading fluency over time. Yet those at highest-risk for poor outcomes, including those living in poverty and those who face learning challenges due to English as a second-language status or special education enrollment, did not make parallel gains to same-age peers in more affluent schools. Implications for educational policy are discussed. 相似文献

Background:Project ECHO (Extension for Community Healthcare Outcomes) is a telehealth initiative that aims to reduce disparities in delivery of health care by leveraging technology and local expertise to provide guidance on specialized subjects to health care providers across the world. In 2018, a new ECHO hub convened in Indianapolis with a focus on health care for individuals in the lesbian, gay, bisexual, trans, and queer (LGBTQ+) populations. This ECHO iteration was one of the first of its kind and would soon be followed by a new human immunodeficiency virus (HIV) ECHO as well.Case Presentation:In a novel approach, information professionals participated in the early planning stages of the formation of these ECHO teams, which enabled the provision of real-time medical evidence and resources at the point-of-need once the teams were launched. This case study demonstrates proof of concept for including health sciences librarians and/or information professionals in the ECHO as hub team members. In this case study, the authors describe and quantify the value added to the HIV and LGBTQ+ ECHO sessions by the medical librarians, as well as provide a template for how other telehealth initiatives can collaborate with their local health information professionals.Conclusions:Librarian involvement in Project ECHO over the past three years has been enthusiastically received. The librarians have contributed hundreds of resources to ECHO participants, helped build and curate resource repositories, and expanded the embedded librarian program to an additional two ECHO iterations. ECHO hub team members report high rates of satisfaction with the performance of embedded librarians and appreciate the provision of point-of-need evidence to ECHO participants. 相似文献

AbstractKnee functional disorders are one of the most common lower extremity non-traumatic injuries reported by cyclists. Incorrect bicycle configuration may predispose cyclist to injury but the evidence of an effect of saddle setback on knee pain remains inconclusive. The aim of this study was to determine the effect of saddle setback on knee joint forces during pedalling using a musculoskeletal modelling approach. Ten cyclists were assessed under three saddle setback conditions (range of changes in saddle position ~6 cm) while pedalling at a steady power output of 200 W and cadence of 90 rpm. A cycling musculoskeletal model was developed and knee joint forces were estimated using an inverse dynamics method associated with a static optimisation procedure. Our results indicate that moving the saddle forwards was not associated with an increase of patellofemoral joint forces. On the contrary, the tibiofemoral mean and peak compression force were 14 and 15% higher in the Backward than in the Forward condition, respectively. The peak compression force was related to neither pedal force nor quadriceps muscle force but coincided with the eccentric contraction of knee flexor muscles. These findings should benefit bike fitting practitioners and coaches in the design of specific training/rehabilitation protocols. 相似文献

OBJECTIVE: No published studies have examined childhood abuse and neglect in body dysmorphic disorder (BDD). This study examined the prevalence and clinical correlates of abuse and neglect in individuals with this disorder. METHODS: Seventy-five subjects (69.3% female, mean age=35.4+/-12.0) with DSM-IV BDD completed the Childhood Trauma Questionnaire and were interviewed with other reliable and valid measures. RESULTS: Of these subjects, 78.7% reported a history of childhood maltreatment: emotional neglect (68.0%), emotional abuse (56.0%), physical abuse (34.7%), physical neglect (33.3%), and sexual abuse (28.0%). Forty percent of subjects reported severe maltreatment. Among females (n=52), severity of reported abuse and neglect were .32-.57 standard deviation units higher than norms for a health maintenance organization (HMO) sample of women. Severity of sexual abuse was the only type of maltreatment significantly associated with current BDD severity (r=.23, p=.047). However, severity of sexual abuse did not predict current BDD severity in a simultaneous multiple regression analysis with age and current treatment status. There were other significant associations with childhood maltreatment: history of attempted suicide was related to emotional (p=.004), physical (p=.014), and sexual abuse (p=.038). Childhood emotional abuse was associated with a lifetime substance use disorder (r=.26, p=.02), and physical abuse was negatively associated with a lifetime mood disorder (r=-.37, p=.001). CONCLUSIONS: A high proportion of individuals with BDD reported childhood abuse and neglect. Certain types of abuse and neglect appear modestly associated with BDD symptom severity and with gender, suicidality, and certain disorders. 相似文献

OBJECTIVES: The two aims of this study were to: (1). describe the prevalence and characteristics of domestic adult and child physical violence in the homes of children and adolescents evaluated in a specialized sexual abuse clinic and (2). describe parent or caretaker responses to domestic adult and child violence and child sexual abuse, including tendencies to report or seek medical care. METHOD: A consecutive sample of 164 subjects (ages 7-19) were interviewed in a sexual abuse clinic regarding in-home violent or abusive experiences among family members that had occurred at any time during their childhood. RESULTS: Fifty-two percent of these children and teenagers reported spousal violence in their home. Fifty-eight percent of child sexual offenders who were in-home males also physically abused their adult female partner. Half of in-home males who were physically violent to children also sexually abused them. In 86% of homes with partner violence, the children were also physically assaulted. There was no difference in sexual abuse disclosure rates or patterns for children living with or without adult violence. CONCLUSIONS: Sexually abused children should be questioned about physical abuse and the presence of violence among adults in their home. Safety plans for sexually abused children should incorporate screening for family violence and safety plans for parents and siblings of child victims, when appropriate. 相似文献

Besides its regulation by Union Cycliste Internationale, the evidence relating saddle setback to pedalling performance remains inconclusive. This study investigates the influence of saddle setback on pedalling effectiveness through two indexes: an index of pedalling force effectiveness and an index of pedalling work effectiveness. Eleven cyclists were assessed six saddle setback conditions while pedalling at a steady power output of 200 W and cadence of 90 rpm. A force sensor was integrated within the seat post to compute the centre of pressure on the saddle. From instrumented pedals, an index of force effectiveness (ratio between the force directed perpendicular to the crank arm and the total force applied to the pedal) and an index of work effectiveness (based on the minimisation of negative crank work) were calculated. In comparison with a forward position, sitting backward significantly decreased 5% cumulative total work, increased index of work effectiveness (84.2 ± 3.7 vs. 82.0 ± 4.7%), and increased index of force effectiveness (41.7 ± 2.9 vs. 39.9 ± 3.7 and 36.9 ± 0.7%). Thus, while it was previously reported that sitting more forward favours maximal power, this study demonstrates that it also leads to a decreased effectiveness in steady-state pedalling. 相似文献
