This paper focuses on analysing the process of partnership formation and its effects on academic performance. We model the formation of studying partnerships as a Bayesian game. Students utility functions are in the spirit of firms' profit functions where the time they devote to study is the input to produce human capital. Academic skills are uniformly distributed, and every student is assumed to know her academic skills. We find that a student decides to study with a classmate because she believes that the classmate has better academics skills. We also find that, in equilibrium, the time a student is willing to spend studying with a classmate increases with the mean and the variance of the distribution of the academic skills. Therefore, under incomplete information, we expect students to devote more time studying with a classmate regardless whether they are studying in a high standard school.

Abstract Objective: This study examined longitudinal associations between performance on the Rey–Osterrieth Complex Figure–Developmental Scoring System (ROCF-DSS) at 8 years of age and academic outcomes at 16 years of age in 133 children with dextro-transposition of the great arteries (d-TGA). Method: The ROCF-DSS was administered at the age of 8 and the Wechsler Individual Achievement Test, First and Second Edition (WIAT/WIAT-II) at the ages of 8 and 16, respectively. ROCF-DSS protocols were classified by Organization (Organized/Disorganized) and Style (Part-oriented/Holistic). Two-way univariate (ROCF-DSS Organization × Style) ANCOVAs were computed with 16-year academic outcomes as the dependent variables and socioeconomic status (SES) as the covariate. Results: The Organization × Style interaction was not statistically significant. However, ROCF-DSS Organization at 8 years was significantly associated with Reading, Math, Associative, and Assembled academic skills at 16 years, with better organization predicting better academic performance. Conclusions: Performance on the ROCF-DSS, a complex visual-spatial problem-solving task, in children with d-TGA can forecast academic performance in both reading and mathematics nearly a decade later. These findings may have implications for identifying risk in children with other medical and neurodevelopmental disorders affecting brain development.

The objective of this study was to verify the association of psychological factors and body practices with the academic performance of high school students. A sample of 330 students participated, made up of 167 girls and 163 boys. Likert scale instruments were used for collecting information on self-concept, and on general and academic self-efficacy. Time spent on moderate to vigorous physical activity was recorded, and so was participation in several types of body practices, such as sports, dances, martial arts, performing arts, and systematic physical exercises. Academic achievement was referred to from the students' grades on regular subjects. Linear regression analysis was used for verifying the association of independent variables with academic performance. The adjusted regression model explains between 7% and 36% of academic performance variance, whereas Self-Concept explains academic performance on six of the twelve subjects, and the mean of the grades, with Beta values between 0.13 (p = 0.02) for Sociology and 0.28 (p <0.01) for Mathematics. Academic self-efficacy explained performance on eleven subjects and the mean of the grades, with Beta values between 0.21 (p <0.01) for Physical Education and Philosophy, and 0.44 (p <0.01) for Biology. Participation in extracurricular activities involving body practices explained academic performance on six subjects and the mean of the grades, with Beta values between 0.14 (p = 0.02) for Sociology and 0.31 (p <0.01) for Arts. The studied psychological variables and participation in projects concerning body practices during extracurricular activities correlated with academic achievement as to several school subjects, and with the mean of the grades.

Background: Signage provides information and direction. It is important as a medium to show direction in offices and public buildings. It is more crucial for emergency services, specifically hospitals. Incomplete information and confusion of signage are among common issues being raised by the public to hospital management. Objective:This study is carried out to determine user height preferencesof Hospital Kajangs signage and to proposean appropriate height forits future signage. Approach: Thirty five respondents (20male and 15 female) participated in this study. They are aged between 18 to 60 years old with the mean of age at39years old. Their stature height and eye-level height are measured using SECA Stable Stadiometer.They are asked to give a rating using 1-10 scaleon threequestions to measure their preferences towards the present signage.The studied signage is also measured using standard measuring tape. The data is analyzed using SPSS.Results:It is found that 25 respondents (71.43%) agree to say that the height of signage in Hospital Kajang is too highwhile10 of them (28.57%) disagree. The signage should be10.5 cm lower from present height in order to optimize its function for both groups. The proposed signage height should be 187.5 cmfrom the floor. Conclusion:The present signage in Hospital Kajang requires necessaryheight readjustment to satisfythe majority of its staffs and visitors. The improvement is vital to ensure the signage meet the directional purpose.

The purpose of this study was to evaluate whether anxiety and depression have a negative effect on academic performance. This small-scale study assessed the relationship between these factors. A cross-sectional questionnaire survey was carried out. A randomized sample of 52 high school students based in various schools across Lahore participated in the survey. Of the participants, 32 were males and 20 were females. As a measure of anxiety and depression 14 questions from the DASS-21 were utilized (The 7 questions pertaining to the measure of stress were not included in this study). Based on the DASS-21 score obtained by the respondents they were classified under categories of normal, mild, moderate, severe and extremely severe levels of anxiety and depression. As a measure of academic performance, the Grade Point Average (GPA) of the students was obtained via the survey. The mean average GPA was calculated for all the students falling under the aforementioned categories pertaining to anxiety and depression separately and these averages were compared. It was found that the mean average GPA was highest in students falling under the categories of normal and mild levels of anxiety and depression. Whereas, mean average GPA was lower in students suffering from severe levels of anxiety and depression. These findings suggest the need to come up with methods to combat anxiety and depression in high school students as these factors impede academic performance.

Summary Objective: In contrast to humans, neutrophil myeloperoxidase deficiency (MPOD) has been rarely investigated in dogs. The hematology analyzer ADVIA®120 differentiates leukocytes based on the cellular volume and their myeloperoxidase concentration. The aim of this study was the characterization of myeloperoxidase deficiency in dogs and the evaluation of the diagnostic use of the ADVIA®120 Myeloperoxidase Index (MPXI). Material and methods: ADVIA® peroxidase scatter plots indicative of MPOD were reviewed. Severity of MPOD was classified semiquantitatively in three groups (MPOD grade 1–3): MPOD grade 1 (MPOD-1): neutrophils showing an abnormal shift of the population, < 25% extending in the monocyte cluster and therefore misclassified, MPOD-2: ~25–50% of neutrophils misclassified, MPOD-3: 50–100% of the neutrophils misclassified due to their location in the monocyte cluster. Sex, age, and breed of the dogs as well as diagnosis, and MPXI were recorded. Results: 29 dogs (nine females and 20 males belonging to 23 breeds) with 38 analyses consistent with MPOD were found. Diseases were characterized by severe leukocyte consumption and included mainly parvovirosis (8/29), DIC/sepsis (3/29), pyometra, pyothorax, pneumonia, pancreatic abscess, and cystitis. A significantly lower mean MPXI in MPOD-3 was present in comparison to the mean MPXI of MPOD-1 (p < 0.05), however, there was a great overlap between the groups. Conclusion: Diseases associated with neutrophil consumption may show an acquired MPOD in dogs. High standard deviation limits the diagnostic use of the MPXI for detection of MPOD. Clinical relevance: The ADVIA®120 cytograms are a good screening tool for detection of MPOD in dogs, but the use of the MPXI is impaired in this species.

Physical activity (PA) may improve brain development, cognition, concentration and academic performance. In this prospective controlled intervention study, we increased the level of PA in 338 children aged 6–8 years at study start, from the Swedish standard of 60 min per week to 200 min per week (40 min daily). The intervention continued in all nine compulsory school years until the students graduated between 2007–2012. All other 689,881 Swedish children who graduated the same years were included as a control group. We registered at graduation eligibility rate for upper secondary school and the final grade score (from 0 to 320 grade points). We also registered the same end points in the 295 students in the index school and in all other 471,926 Swedish students who graduated in 2003–2006, that is, those who graduated before the intervention study started. Before the intervention, academic performance was similar among children in the index school as for all other Swedish boys and girls. With the intervention, the eligibility rate increased for boys in the index school by 7.3 percentage points and the mean grade scores by 13.3 points. This should be compared with a decrease of 0.8 percentage points in eligibility rate and an increase by 2.7 points in grade score in other Swedish boys. No changes were seen for intervention girls, neither in eligibility rates or grade scores. By introducing daily school-based PA in compulsory school, more boys would probably reach the eligibility rate for higher education.

Until recently, wear studies of orthopaedic biomaterials have suffered from inadequate testing capacity and high standard deviation (SD) of results. In the present article, the previously validated 100-station hip wear simulator, the SuperCTPOD, is evaluated with regard to its capability of producing statistically significant differences in mean wear rates. SuperCTPOD wear tests were done for 38 different types of polyethylene pins against polished CoCr discs with diluted calf serum lubrication. A total of 200 pins were worn in two consecutive tests of 6 weeks, duration each. The sample size varied from four to six. The mean wear rates of the samples ranged from 0.52 to 77.1 mg per one million cycles. On the average, the SD of the wear rate was 4.2 per cent of the mean value (range 1–8.5 per cent). A difference in the mean wear rates below 5 per cent was large enough to be statistically significant ( p <0.05) in 21 comparisons between two samples, the lowest statistically significant mean difference being 3.2 per cent. In conclusion, the high capacity and the low SD of the wear rate make the SuperCTPOD wear test system unparalleled in efficiency. The observations regarding the effect of crosslinking and molecular weight on polyethylene wear resistance were in agreement with studies published earlier.

This study is a mixed method design which employed both quantitative and qualitative methods in order to investigate the impact of dialogic learning on students’ attention and academic achievement. Data were collected using several instruments, including: the Attention Network Test; academic performance tests and semi-structured interviews. Results of Analysis of Covariance (ANCOVA) indicated that there is a statistically significant difference between the mean scores of students of the experimental and control groups on the executive control in favor of the experimental group after controlling the IQ score and pre-test scores. Further, there is a statistically significant difference between the mean scores of student of the experimental and control groups on the academic achievement tests (except of mathematics) in favor of the experimental group. The qualitative data also supported the quantitative findings. Therefore, dialogic teaching has significantly greater and more positive changes on some aspects of attention and academic performance.
