The relationship between parenting practices and juvenile delinquency

Delinquency may take on many definitions, but the most widely accepted definition is a minor crime committed by a young person, generally under the age of 18. Youth may also deal with legal trouble in response to status offending. These are behaviors that are age-based and would not be charged if committed by an adult. Examples include truancy, running away, drinking alcohol and using tobacco, and being incorrigible. Offending is a term that can be used to describe the actions of adults and youth, with definitions extending beyond just a “minor” crime (e.g., homicides and rapes). Many factors may contribute to delinquency, status offending, and criminal offending, with parenting and parental attachment commonly cited amongst correctional research. Studies show that parental attachment and parenting styles have a direct effect on youth and their subsequent delinquent or offending behavior(s). This poster outlines the research on associations between parenting styles and justice system involvement as well as policy implications

Barefoot Running: The Effects of an 8-Week Barefoot Training Program

A grant from the One-University Open Access Fund at the University of Kansas was used to defray the author’s publication fees in this Open Access journal. The Open Access Fund, administered by librarians from the KU, KU Law, and KUMC libraries, is made possible by contributions from the offices of KU Provost, KU Vice Chancellor for Research & Graduate Studies, and KUMC Vice Chancellor for Research. For more information about the Open Access Fund, please see http://library.kumc.edu/authors-fund.xml.Background: It has been proposed that running barefoot can lead to improved strength and proprioception. However, the duration that a runner must train barefoot to observe these changes is unknown. Hypothesis: Runners participating in a barefoot running program will have improved proprioception, increased lower extremity strength, and an increase in the volume or size of the intrinsic musculature of the feet. Study Design: Randomized controlled trial; Level of evidence, 2. Methods: In this 8-week study, 29 runners with a mean age of 36.34 years were randomized into either a control group (n = 10) who completed training in their regular running shoes or to an experimental barefoot group (n = 14). Pretraining tests consisted of a volumetric measurement of the foot followed by a strength and dynamic balance assessment. Five subjects completed the pretests but did not complete the study for reasons not related to study outcomes. Participants then completed 8 weeks of training runs. They repeated the strength and dynamic balance assessment after 8 weeks. Results: Significant changes from baseline to 8 weeks were observed within the barefoot group for single-leg hop (right, P = .0121; left, P = .0430) and reach and balance (right, P = .0029) and within the control group for single–left leg hop (P = .0286) and reach and balance (right, P = .0096; left, P = .0014). However, when comparing the differences in changes from baseline to 8 weeks between the barefoot and control groups, the improvements were not significant at the .05 level for all measures. Conclusion: Although statistically significant changes were not observed between the pre- and posttest evaluations in strength and proprioception with the 8-week low-intensity barefoot running regimen, this does not necessarily mean that these changes do not occur. It is possible that it may take months or years to observe these changes, and a short course such as this trial is insufficient

Review of Variability in Rehabilitation Protocols after Lateral Ankle Ligament Surgery

Introduction. Ankle sprains are one of the most common athletic injuries. If a patient fails to improve through conservative management, surgery is an option to restore ankle stability. The purpose of this study was to analyze and assess the variability across different rehabilitation protocols for patients undergoing either lateral ankle ligament repair, reconstruction, and suture tape augmentation. Methods. Using a web-based search for published rehabilitation protocols after lateral ankle ligament repair, reconstruction, and suture tape augmentation, a total of 26 protocols were found. Inclusion criteria were protocols for post-operative care after an ankle ligament surgery (repair, reconstruction, or suture tape augmentation). Protocols for multi-ligament surgeries and non-operative care were excluded. A scoring rubric was created to analyze different inclusion, exclusion, and timing of protocols such as weight-bearing, range of motion (ROM), immobilization with brace, single leg exercises, return to running, and return to sport (RTS). Protocols inclusion of different recommendations was recorded along with the time frame that activities were suggested in each protocol. Results. Twenty-six protocols were analyzed. There was variability across rehabilitation protocols for lateral ankle ligament operative patients especially in the type of immobilizing brace, time to partial and full weigh bearing, time to plantar flexion, dorsiflexion, eversion and inversion movements of the ankle, and return to single leg exercise and running. For repair and reconstruction, none of these categories had greater than 60% agreement between protocols. All (12/12) repair, internal brace, and unspecified protocols and 86% (12/14) of reconstruction protocols recommended no ROM immediately postoperatively. Eighty-six percent (6/7) of repair and 78% (11/14) of reconstruction protocols recommended no weight-bearing immediately after surgery, making post-operative ROM and weight-bearing status the most consistent aspects across protocols. Five protocols allowed post-operative weight-bearing in a cast to keep ROM restricted. Sixty-six percent (2/3) of suture tape augmentation protocols allowed full weight-bearing immediately post-operatively. Suture tape augmentation protocols generally allowed rehabilitation to occur on a quicker time-line with full weight-bearing by week 4-6 in 100% (3/3) of protocols and full ROM by week 8-10 in 66% (2/3) protocols. RTS was consistent in repair protocols (100% at week 12-16) but varied more in reconstruction. Conclusion. There is significant variability in the post-operative protocols after surgery for ankle instability. ROM was highly variable across protocols and did not always match-up with supporting literature for early mobilization of the ankle. Return to sport was most likely to correlate between protocols and the literature. Weight-bearing was consistent between most protocols but requires further research to determine the best practice. Overall, the variability between programs demonstrated the need for standardization of rehabilitation protocols

Return to Sport After Primary Anterior Cruciate Ligament (ACL) Reconstruction: A Survey of The American Orthopaedic Society for Sports Medicine

Introduction. Anterior cruciate ligament (ACL) tears are a common sports injury, and typically require a prolonged post operative rehabilitation. The purpose of this study was to survey members of the American Orthopaedic Society for Sports Medicine (AOSSM) to determine their return to sport (RTS) criteria after primary ACL reconstruction (ACLR). Methods. A 23 question, anonymous survey hosted through Google Docs was distributed electronically to AOSSM members. This survey included questions regarding the timing, as well as any functional tests or other metrics used to determine when an athlete is ready to RTS. Results. 863 surgeons responded over four months. The most popular graft choice was bone patellar tendon bone autograft (63%). For non-pivoting sports, 43% of respondents allowed RTS at 5 - 6 months, while 31% allowed RTS at 7 - 8 months. For pivoting sports, 34% of respondents allowed RTS at 7 - 8 months, while 36% allowed RTS at 9 - 10 months. The most common criteria for return to non-pivoting sports include full knee motion (89%) and time after ACLR (76%). The most common criteria for return to pivoting sports include full knee motion (87%) and passing a hop test (80%). Only 21% of respondents assessed for psychological readiness to RTS. Conclusions. RTS occurred sooner in non-pivoting than pivoting sports, with similar RTS criteria in both groups. Most respondents do not assess for psychological readiness to RTS

Initial Response of Mature, Experienced Runners to Barefoot Running: Transition to Forefoot Strike

Introduction Forefoot strike has been advocated for many runnersbecause of the relatively lower impact and push-off forces comparedto a heel strike. The purpose of this study was to explore the abilityof mature (> 30 years old), experienced runners to transition from aheel foot strike to a forefoot strike when first introduced to barefootrunning on a treadmill. We hypothesized: 1) mature runners who heelstrike while wearing traditional training shoes would persist in heelstriking immediately following a switch to barefoot, 2) mean shoeheel-to-toe drop would be significantly greater in runners who persistin heel striking when running barefoot compared to those who transitionto a forefoot strike pattern, and 3) there would be a significantdecrease in heel striking in the barefoot condition as running speedsincreased. Methods This was a controlled crossover laboratory study. Thirty-three experienced runners (average 23.4 miles per week) withan average age of 45.6 years were recruited for this study. The participantsfirst ran in their standard running shoes and subsequentlybarefoot. A motion capture system was utilized to detect and analyzeany transition from heel strike to forefoot strike made by study participants. Results Of the 26 participants who were classified as heel strikerunners in their running shoes, 50% (13/26, p = 0.001) transitionedto forefoot strike when changing from running in shoes to runningbarefoot. Conclusions The injuries associated with transition from standardrunning shoes to barefoot running or minimalist shoes may be influencedby the persistence of heel striking in mature runners. Olderexperienced runners may have limited ability to transition from heelto forefoot striking when first introduced to barefoot running. Maturerunners should be cautious when beginning a minimalist shoe orbarefoot running regimen

The James Webb Space Telescope Mission

Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least $4m$. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the $6.5m$ James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 years, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space Telescope Overview, 29 pages, 4 figure
