Published: November 2017

IntroductionTo assess the mode of sit-to-stand (STS) task performed in a habitual manner or with flexion or extension pattern transfer in asymptomatic young subjects. It was hypothesized that different initial movements of the lumbar-pelvic region would modify the performance of the STS task: coordination of STS in time and level of vertical ground reaction forces (VGRF).MethodsA convenience sample of 30 young asymptomatic volunteers, both genders, was recruited. The STS task was performed in a habitual manner or with a flexion or extension pattern. A Kistler platform was used to measure the VGRF and time of STS phases.ResultsANOVAs analysis revealed the main effect in the total time and in maximum VGRF during the STS manoeuvre in three STS tasks (F(2, 58) = 21.67–30.74; <i>p</i> < 0.00001). In the post-hoc analysis, there was no difference in the total time between flexion and extension pattern of STS (<i>p</i> > 0.05), there was no difference between the flexion and extension pattern in minimum VGRF (<i>p</i> > 0.05), but the latter task was the longest in preparation time (<i>p</i> < 0.001). The lowest maximum VGRF was bound with the extension pattern of STS (<i>p</i> < 0.01).ConclusionsThe extension or flexion movement pattern modified STS performance and displayed different coordination in time and level of VGRF. Young asymptomatic participants performed the STS task longer with flexion or extension pattern than in the habitual pattern. The extension pattern of STS had the capacity to produce the lowest VGRF.
Multicomponent Gause’s principle in models of biological communities
Authors: Razzhevaikin Valery N. 
Published: November 2017

AbstractA generalization of the Gause competitive exclusion principle which guarantees the vanishing of at least one species in the community exceeding in number of species the number of available resources is presented. Theorems which guarantee the vanishing of a greater number of components under condition of the Malthusian vector function localizations in a set of smaller dimension are formulated. The theory developed here is applied to the case of Volterra type systems for which such vector functions are linear resource dependent and the number of resources is small.

Authors: Prakash Jyoti , Kumar Rajeev , Kumari Kultaran 
Published: November 2017

Abstract
The effect of magnetic field dependent (MFD) viscosity on thermal convection in a horizontal ferromagnetic fluid layer has been investigated numerically. A correction is applied to Sunil et al. [24] which is very important in order to predict the correct behavior of MFD viscosity. Linear stability analysis has been carried out for stationary convection. The MFD viscosity parameter δ as well as the measure of nonlinearity of magnetization M
3, both have a stabilizing effect on the system. Numerical results are also obtained for large values of magnetic parameter M

Published: November 2017

Abstract
The aim of this study was to evaluate the impact of increased homocysteine levels induced by methionine nutritional overload (twice as standard) and deficiency of the vitamins folate, pyridoxine and cobalamine, which plays an important role in homocysteine metabolism in anxiety-related behaviour, expressed by means of exploratory activity in rats. Twenty-three male Wistar albino rats (4 weeks old, 100±15 g body weight) were divided into three groups: control (n=8), methionine-enriched (Meth+, 7.7 g of methionine/kg chow, n=7) and methionine-enriched vitamin-deficient (Meth+Vit-, 7.7 g of methionine/ kg chow, deficient in folate, pyridoxine and cobalamine - 0.08, 0.01 and 0.01 mg/kg, n=8). All animals had free access to food and water for 30 days. Behavioural testing was performed using the elevated plus maze (EPM) test. Standard parameters for vertical exploratory activity, the number of rearings and the number of head-dippings, as well as the total exploratory activity (summarizing overall exploratory activity in the EPM) were significantly reduced following 30 days of methionine nutritional overload (p<0.05, p<0.05 and p<0.01, respectively). A methionine-enriched diet coupled with a reduction in some B vitamins resulted in a more pronounced decline in exploratory drive observed in the EPM test compared to the control (p<0.01). The decline in total exploratory activity associated with vitamin deficiency was significant compared to the Meth+ group (p<0.05). The results of this study highlight the important role of homocysteine in the modulation of exploratory activity in rats. Decreased exploratory drive induced by both a methionine-enriched and vitamin-deficient diet could be attributed to an anxiogenic effect of hyperhomocysteinemia.

Authors: Johnson Bernadette K. , Brou Lina , Fields Sarah K. , Erkenbeck Alexandria N. , Comstock R. Dawn 
Published: November 2017

BACKGROUND:
The risk of hand/wrist injuries is present across various sports. Little is known about the epidemiology of such injuries. The objective of this study was to calculate the rates of hand/wrist injuries and investigate injury patterns among high school athletes.

METHODS:
Athlete exposure (AE) and hand/wrist injury data were collected during 11 academic years, 2005/06 through 2015/16, from a large sample of US high schools as part of the National High School Sports-Related Injury Surveillance Study.

RESULTS:
There were 6723 hand/wrist injuries sustained during 40 195 806 AEs, a rate of 1.7 per 10 000 AEs. The rate of injury in competition (3.3) was higher than in practice (1.1) (95% confidence interval: 2.8–3.1). Rates of hand/wrist injuries varied by sport, with the highest rates in football (4.3), boys’ lacrosse (1.9), girls’ softball (1.9), wrestling (1.8), girls’ field hockey (1.7), boys’ ice hockey (1.7), and girls’ basketball (1.7). The most common injuries were fracture (45.0%), contusion (11.6%), and ligament sprain (9.0%). Athletes most frequently returned to play in &lt;7 days (45.7%), but 12.4% of injuries kept athletes out ≥3 weeks.

CONCLUSIONS:
High school athletes are at risk for hand/wrist injuries. Such injuries can keep athletes out of play and many require substantial medical treatment. Stick and ball or puck sports and full contact sports have high rates of hand/wrist injuries relative to other sports, which is indicative of a need for sport-specific prevention efforts.

Published: November 2017

AbstractThe aim of this study was to examine the relationship between goal orientations, learning approaches and academic achievement, and to examine the possibility of predicting academic achievement through goal orientations and learning approaches. A sample of N = 346 male and female second and third year undergraduate and first year graduate students of different colleges and sections of the University of J.J.Strossmayer in Osijek participated in this study. The results indicate that academic achievement is in a positive correlation with the mastery and performance goal orientations and deep and strategic learning approaches, and in a negative correlation with the work-avoidance goal orientation and surface learning approach. Furthermore, the results indicate a positive relationship between the mastery goal orientation and deep and strategic learning approaches and positive relationship between the work-avoidance goal orientation and surface learning approach, and negative between the work-avoidance goal orientation and deep learning approach. Also, mastery, performance goal orientations and deep learning approach were positive predictors of academic achievement. College was significant moderator of relationship between deep learning approach and academic achievement. Deep learning approach was a positive predictor of achievement in "hard" study disciplines and was not a significant predictor of academic achievement in "soft" study disciplines.Key words: learning; motivation; performance. ---Sažetak Cilj je ovog rada bio ispitati odnos ciljnih orijentacija u učenju, pristupa učenju i akademskog uspjeha kod studenata te provjeriti mogućnost predviđanja akademskog uspjeha na temelju ciljnih orijentacija u učenju i pristupa učenju.

Published: November 2017

AbstractThe aim of this study was to explore relationships between one of the behavioral definitions of quality educational practice (ISSA’s Definition of Quality) and the implicit theories on gifted teachers held by four groups of study participants (N = 199). If giftedness is valued across different performance domains, including education, the question that needs to be addressed is whether there are gifted teachers, and how they can be identified. Using profile analysis, two groups of teachers, pre-service teachers (n = 47), and experts (n = 61), rated the proposed quality indicators as behaviors highly indicative of their exemplary gifted teachers. This offers support to the construct validity of operationalization of gifted teachers as those competently demonstrating consensually agreed upon indicators of quality at a high level, across different focus areas of educational practice. The results were interpreted in accordance with the contemporary, empirically proven influence of teachers on students' learning and the outcomes of this learning. Special emphasis was placed on the behavioral operationalization of quality in educational practice, and how it overlaps with the construct of giftedness as manifested in adulthood (in competence, in expertise, and finally, in eminence), suggesting inclusion of education as one of the giftedness performance domains. Key words: education quality; expertise; giftedness domains; quality teaching.---SažetakCilj je ovoga istraživanja bio ispitati odnose između jedne ponašajne definicije kvalitetne pedagoške prakse (ISSA) i implicitnih teorija o darovitim učiteljima na četiri skupine sudionika (N = 199). Ako je darovitost cijenjena u različitim domenama, uključujući obrazovanje, tko su daroviti učitelji i koje su njihove odlike? Uporabom analize profila, i učitelji početnici (n = 47) i ekspertni učitelji (n = 61) procijenili su ponuđeni skup indikatora kvalitetne pedagoške prakse kao visoko indikativan za primjerne darovite učitelje. Taj podatak pruža podršku konstruktnoj valjanosti operacionalizacije darovitih učitelja kao onih koji kompetentno pokazuju konsenzusno dogovorene indikatore kvalitete na visokoj razini u različitim područjima pedagoške prakse. Rezultati su interpretirani u skladu sa suvremenim, empirijski utvrđenim utjecajem učitelja na učenikovo učenje i ishode toga učenja. Poseban je naglasak stavljen na ponašajnu operacionalizaciju kvalitetne pedagoške prakse, kao i na načine kako se ona preklapa s konstruktom darovitosti i njezinom manifestacijom u odrasloj dobi (u kompetentnosti, u ekspertnosti, i na kraju, u eminentnosti), uz prijedlog ubrajanja obrazovanja u jedno od domena darovitosti.

Evaluating Public Health Interventions: 7. Let the Subject Matter Choose the Effect Measure: Ratio, Difference, or Something Else Entirely
Authors: Spiegelman Donna , Khudyakov Polyna , Wang Molin , Vanderweele Tyler J. 
Published: November 2017

We define measures of effect used in public health evaluations, which include the risk difference and the risk ratio, the population-attributable risk, years of life lost or gained, disability-adjusted life years, quality-adjusted life years, and the incremental cost-effectiveness ratio. Except for the risk ratio, all of these are absolute effect measures.For constructing externally generalizable absolute measures of effect when there is superior fit of the multiplicative model, we suggest using the multiplicative model to estimate relative risks, which will often be obtained in simple linear form with no interactions, and then converting these to the desired absolute measure. The externally generalizable absolute measure of effect can be obtained by suitably standardizing to the risk factor distribution of the population to which the results are to be generalized.External generalizability will often be compromised when absolute measures are computed from study populations with risk factor distributions different from those of the population to whom the results are to be generalized, even when these risk factors are not confounders of the intervention effect.
Does Auditor Locality Matter in Financial Reporting Quality?
Authors: Diaz Jamie , Martin Gregory W. , Thomas Wayne B. 
Published: November 2017

SUMMARY
In this paper, we describe recent findings that auditor localities serve as a conduit for contagion of financial reporting quality between client firms. This “auditor locality contagion” is distinct from contagion within the same audit office and is incremental to national trends in financial reporting quality. These findings are important as practitioners consider factors that may affect audit quality across engagements and within certain audit offices.
Fraud Risk Brainstorming at Tesla Motors
Authors: Hess Megan F. , Andiola Lindsay M. 
Published: November 2017

ABSTRACT
This instructional case offers students the opportunity to explore the fraud risk assessment process and participate in a simulated fraud brainstorming session as required by AS 2401 (formerly SAS 99) for financial statement audits. Drawing on publicly available information about Tesla, Inc. (formerly Tesla Motors), the revolutionary company behind the popular Model S all-electric vehicle, the case materials guide students through multiple learning objectives. These objectives include learning how to: (1) recognize the factors that contribute to financial statement fraud risk; (2) identify and evaluate the likelihood and severity of fraud risks; (3) analyze the ways that fraud risks can lead to material misstatements in the financial statements; (4) understand the purpose of and how to conduct a fraud brainstorming session; and (5) develop audit procedures that respond to assessed fraud risks. In a post-case learning assessment, students reported significant improvement in their knowledge, comprehension, and application of these learning objectives. Students also indicated that they enjoyed learning about these concepts in the context of this popular company. This case has both an individual and a group component, and it is designed for use in an auditing or forensic accounting course at either the undergraduate or the graduate level.

OBJECTIVE
The aim of the present cross-sectional study was to examine the association among physical activity (PA), sedentary time (ST), and cardiometabolic risk in adults with prediabetes.

RESEARCH DESIGN AND METHODS
Participants (n = 2,326; 25–70 years old, 67% female) from eight countries, with a BMI &gt;25 kg ⋅ m−2 and impaired fasting glucose (5.6–6.9 mmol ⋅ L−1) or impaired glucose tolerance (7.8–11.0 mmol ⋅ L−1 at 2 h), participated. Seven-day accelerometry objectively assessed PA levels and ST.

RESULTS
Multiple linear regression revealed that moderate-to-vigorous PA (MVPA) was negatively associated with HOMA of insulin resistance (HOMA-IR) (standardized β = −0.078 [95% CI −0.128, −0.027]), waist circumference (WC) (β = −0.177 [−0.122, −0.134]), fasting insulin (β = −0.115 [−0.158, −0.072]), 2-h glucose (β = −0.069 [−0.112, −0.025]), triglycerides (β = −0.091 [−0.138, −0.044]), and CRP (β = −0.086 [−0.127, −0.045]). ST was positively associated with HOMA-IR (β = 0.175 [0.114, 0.236]), WC (β = 0.215 [0.026, 0.131]), fasting insulin (β = 0.155 [0.092, 0.219]), triglycerides (β = 0.106 [0.052, 0.16]), CRP (β = 0.106 [0.39, 0.172]), systolic blood pressure (BP) (β = 0.078 [0.026, 0.131]), and diastolic BP (β = 0.106 [0.39, −0.172]). Associations reported between total PA (counts ⋅ min−1), and all risk factors were comparable or stronger than for MVPA: HOMA-IR (β = −0.151 [−0.194, −0.107]), WC (β = −0.179 [−0.224, −0.134]), fasting insulin (β = −0.139 [−0.183, −0.096]), 2-h glucose (β = −0.088 [−0.131, −0.045]), triglycerides (β = −0.117 [−0.162, −0.071]), and CRP (β = −0.104 [−0.146, −0.062]).

CONCLUSIONS
In adults with prediabetes, objectively measured PA and ST were associated with cardiometabolic risk markers. Total PA was at least as strongly associated with cardiometabolic risk markers as MVPA, which may imply that the accumulation of total PA over the day is as important as achieving the intensity of MVPA.

In the paper [DLS13], De Lellis and Székelyhidi introduce a method for constructing periodic weak solutions to the incompressible Euler equations

{∂tv+div v⊗v+∇p=0 div v=0

in three spatial dimensions that are continuous but do not conserve energy. The motivation for constructing such solutions comes from a conjecture of Lars Onsager [Ons49] on the theory of turbulence in an ideal fluid. In the modern language of PDE, Onsager's conjecture can be translated as follows....
