Misplaced Misrepresentations: Why Misrepresentation-of-Age Statutes Must Be Reinterpreted as They Apply to Children’s Online Contracts
The information age revolutionized the relationship between individuals and the internet. Today, children are the targets of online advertisements that lure them into accepting terms of service, thus entering into online agreements. While children may feel comfortable navigating websites, they are psychologically predisposed to be unsophisticated and impulsive actors online. Children lack the digital literacy to understand the implications of accepting website terms of service. Meanwhile, several states have misrepresentation-of-age statutes that prevent children from using the infancy doctrine to disaffirm online contracts because, in accepting the terms of service, children often represent that they are old enough to enter into the agreement. This Note argues that the heightened vulnerability of children online requires a reconsideration of the application of misrepresentation-of-age statutes to children’s online contracts. To adequately balance the policy interests in protecting children against misrepresentation statutes’ goal of preventing unknowing adults from being taken advantage of in the marketplace, this Note recommends that judges undertake a fact-specific, contextual inquiry of the online contract formation process
Health promotion in schools: a multi-method evaluation of an Australian School Youth Health Nurse Program
BACKGROUND:
Health promotion provides a key opportunity to empower young people to make informed choices regarding key health-related behaviours such as tobacco and alcohol use, sexual practices, dietary choices and physical activity. This paper describes the evaluation of a pilot School Youth Health Nurse (SYHN) Program, which aims to integrate a Registered Nurse into school communities to deliver health promotion through group education and individual sessions.
METHODS:
The evaluation was guided by the RE-AIM (reach, effectiveness, adoption, implementation, maintenance) framework. The objectives were to explore: 1) whether the Program was accessible to the high school students; 2) the impacts of the Program on key stakeholders; 3) which factors affected adoption of the Program; 4) whether implementation was consistent with the Program intent; and 5) the long-term sustainability of the Program. Research included retrospective analysis of Program records, administration of a survey of student experiences and interviews with 38 stakeholders.
RESULTS:
This evaluation provided evidence that the SYHN Program is reaching students in need, is effective, has been adopted successfully in schools, is being implemented as intended and could be maintained with sustained funding. The nurses deliver an accessible and acceptable primary health care service, focused on health promotion, prevention and early intervention. After some initial uncertainty about the scope and nature of the role, the nurses are a respected source of health information in the schools, consulted on curriculum development and contributing to whole-of-school health activities.
CONCLUSIONS:
Findings demonstrate that the SYHN model is feasible and acceptable to the students and schools involved in the pilot. The Program provides health promotion and accessible primary health care in the school setting, consistent with the Health Promoting Schools framework.This project was supported by funding from the Australian Capital Territory

The chronotype of elite athletes
The aims of this study were (i) to compare the chronotype distribution of elite athletes to a young adult population and (ii) to determine if there was a tendency for athletes to select and/or participate in sports which suited their chronotype. A total of 114 elite athletes from five sports (cricket, cycling, hockey, soccer and triathlon) participated in this study. The participants’ chronotype, sleepiness, sleep satisfaction and sleep quality were determined using the Horne and Östberg Morningness and Eveningness questionnaire, the Epworth Sleepiness Scale and questions concerning their sleep satisfaction and quality. All questionnaires were administered during a typical training phase that was not in the lead up to competition and/or post competition. No differences between chronotype group for sleepiness, sleep satisfaction or sleep quality were found. There was a significantly higher proportion of triathletes that were morning and intermediate types compared to the control group χ2 (2) = 7.5, p = 0.02. A significant relationship between sport and chronotype group (χ2(4)=15.9, p = 0.04) was observed, with a higher frequency of morning types involved in sports that required morning training. There was a clear indication that athletes tended to select and pursue sports that suited their chronotype. This was evident by the amount of morning types involved in morning sports. Given that athletes are more likely to pursue and excel in sports which suit their chronotype, it is recommended that coaches consider the athlete’s chronotype during selection processes or if possible design and implement changes to training schedules to either suit the athletes’ chronotype or the timing of an upcoming competition
Implementation of continuous quality improvement in Aboriginal and Torres Strait Islander primary health care in Australia: a scoping systematic review
BACKGROUND: Continuous Quality Improvement (CQI) programs have been taken up widely by Indigenous primary health care (PHC) services in Australia and there has been national policy commitment to support this. However, international evidence shows that implementing CQI is challenging, impacts are variable and little is known about the factors that impede or enhance effectiveness. A scoping review was undertaken to explore uptake and implementation in Indigenous PHC, including barriers and enablers to embedding CQI in routine practice. We provide guidance on how research and evaluation might be intensified to support implementation.
METHODS: Searches were conducted in MEDLINE, CINAHL and the Cochrane Database of Systematic Reviews. Key websites and publications were handsearched. Studies conducted in Indigenous PHC which demonstrated some combination of CQI characteristics and assessed some aspect of implementation were included. A two stage analysis was undertaken. Stage 1 identified the breadth and focus of literature. Stage 2 investigated barriers and enablers. The Framework for Performance Assessment in PHC (2008) was used to frame the analysis. Data were extracted on the study type, approach, timeframes, CQI strategies, barriers and enablers.
RESULTS: Sixty articles were included in Stage 1 and 21 in Stage 2. Barriers to implementing CQI processes relate primarily to professional and organisational processes and operate at multiple levels (individual, team, service, health system) whereas barriers to improved care relate more directly to knowledge of best practice and team processes that facilitate appropriate care. Few studies described implementation timeframes, number of CQI cycles or improvement strategies implemented and only two applied a change theory.
CONCLUSION: Investigating barriers and enablers that modify implementation and impacts of CQI poses conceptual and methodological challenges. More complete description of CQI processes, implementation strategies, and barriers and enablers could enhance capacity for comparisons across settings and contribute to better understanding of key success factors
Quantitative myocardial perfusion in mice based on the signal intensity of flow sensitized CMR
Thrombospondin-3 augments injury-induced cardiomyopathy by intracellular integrin inhibition and sarcolemmal instability.
Thrombospondins (Thbs) are a family of five secreted matricellular glycoproteins in vertebrates that broadly affect cell-matrix interaction. While Thbs4 is known to protect striated muscle from disease by enhancing sarcolemmal stability through increased integrin and dystroglycan attachment complexes, here we show that Thbs3 antithetically promotes sarcolemmal destabilization by reducing integrin function, augmenting disease-induced decompensation. Deletion of Thbs3 in mice enhances integrin membrane expression and membrane stability, protecting the heart from disease stimuli. Transgene-mediated overexpression of α7β1D integrin in the heart ameliorates the disease predisposing effects of Thbs3 by augmenting sarcolemmal stability. Mechanistically, we show that mutating Thbs3 to contain the conserved RGD integrin binding domain normally found in Thbs4 and Thbs5 now rescues the defective expression of integrins on the sarcolemma. Thus, Thbs proteins mediate the intracellular processing of integrin plasma membrane attachment complexes to regulate the dynamics of cellular remodeling and membrane stability
A validation study of a commercial wearable device to automatically detect and estimate sleep
The aims of this study were to: (1) compare actigraphy (ACTICAL) and a commercially available sleep wearable (i.e., WHOOP) under two functionalities (i.e., sleep auto-detection (WHOOP-AUTO) and manual adjustment of sleep (WHOOP-MANUAL)) for two-stage categorisation of sleep (sleep or wake) against polysomnography, and; (2) compare WHOOP-AUTO and WHOOP-MANUAL for four-stage categorisation of sleep (wake, light sleep, slow wave sleep (SWS), or rapid eye movement sleep (REM)) against polysomnography. Six healthy adults (male: n = 3; female: n = 3; age: 23.0 ± 2.2 yr) participated in the nine-night protocol. Fifty-four sleeps assessed by ACTICAL, WHOOP-AUTO and WHOOP-MANUAL were compared to polysomnography using difference testing, Bland–Altman comparisons, and 30-s epoch-by-epoch comparisons. Compared to polysomnography, ACTICAL overestimated total sleep time (37.6 min) and underestimated wake (−37.6 min); WHOOP-AUTO underestimated SWS (−15.5 min); and WHOOP-MANUAL underestimated wake (−16.7 min). For ACTICAL, sensitivity for sleep, specificity for wake and overall agreement were 98%, 60% and 89%, respectively. For WHOOP-AUTO, sensitivity for sleep, wake, and agreement for two-stage and four-stage categorisation of sleep were 90%, 60%, 86% and 63%, respectively. For WHOOP-MANUAL, sensitivity for sleep, wake, and agreement for two-stage and four-stage categorisation of sleep were 97%, 45%, 90% and 62%, respectively. WHOOP-AUTO and WHOOP-MANUAL have a similar sensitivity and specificity to actigraphy for two-stage categorisation of sleep and can be used as a practical alternative to polysomnography for two-stage categorisation of sleep and four-stage categorisation of sleep

of the University of Winnipeg some of the
contexts, considerations and principles
necessary when undertaking any future
housing-oriented development. The report
provides general support for the
proposition that – given demonstrated need
for affordable and accessible housing in the

ERK1/2 signaling induces skeletal muscle slow fiber-type switching and reduces muscular dystrophy disease severity
© 2019 American Society for Clinical Investigation. MAPK signaling consists of an array of successively acting kinases. ERK1 and -2 (ERK1/2) are major components of the greater MAPK cascade that transduce growth factor signaling at the cell membrane. Here, we investigated ERK1/2 signaling in skeletal muscle homeostasis and disease. Using mouse genetics, we observed that the muscle-specifc expression of a constitutively active MEK1 mutant promotes greater ERK1/2 signaling that mediates fber-type switching to a slow, oxidative phenotype with type I myosin heavy chain expression. Using a conditional and temporally regulated Cre strategy, as well as Mapk1 (ERK2) and Mapk3 (ERK1) genetically targeted mice, MEK1-ERK2 signaling was shown to underlie this fast-to-slow fber-type switching in adult skeletal muscle as well as during development. Physiologic assessment of these activated MEK1-ERK1/2 mice showed enhanced metabolic activity and oxygen consumption with greater muscle fatigue resistance. In addition, induction of MEK1-ERK1/2 signaling increased dystrophin and utrophin protein expression in a mouse model of limb-girdle muscle dystrophy and protected myofbers from damage. In summary, sustained MEK1-ERK1/2 activity in skeletal muscle produces a fast-to-slow fber-type switch that protects from muscular dystrophy, suggesting a therapeutic approach to enhance the metabolic effectiveness of muscle and protect from dystrophic disease
