    Full Text Available The aim of this article was to classify The Indonesian Scholastic Aptitude Test or Tes Bakat Skolastik (TBS results for each subtest and describe scholastic aptitudes in each subtest. The subject of this study was 36,125 prospective students who took the selection test in some universities. Data analysis began by estimating  testees’ ability using the Item Response Theory, and benchmarking process using the scale anchoring method applying ASP.net web server technology. The results of this research are four benchmarks (based on cutoff scores on each subtest, characters which differentiate potential for each benchmark, and measurement error on each benchmark. The items netted give a description of the scholastic aptitude potential clearly and indicate uniqueness so that it could distinguish difference in potential between a lower bench and a higher bench. At a higher bench, a higher level of reasoning power is required in analyzing and processing needed information so that the individual concerned could do the problem solving with the right solution. The items netted at a lower bench in the three subtests tend to be few so that the error of measurement at such a bench still tends to be higher compared to that at a higher bench.

    Full Text Available Test for measuring vocational aptitude has been formulated and validated. There are three main constructs involved in vocational aptitude test, which are individual characteristics, activities that are likely to be selected, and professions that tend to be idolized. Individual characteristics indicate the individuals talents, whereas the activity that tends to be chosen leads to student interest in the activity, and the intended profession gives clues about the capability of themselves to pursue the profession. Content validity test with Lawse technique yields content validity ratio (CVR for all items are in the range 0.82-0.94 and content validity index (CVI = 0.88. The construct validity test yields comparative fit index (CFI = 0.918 and chi square coefficient (χ2 = 5.85 with significance (p = 0.002. These findings indicate that the test is valid either by content or construct. Furthermore, the reliability test with Alpha Cronbach found the alpha coefficient (α = 0.82. Finally, it can be concluded that vocational aptitude test can be utilized for early identification of student vocational aptitude. The hope, the test can help students to choose the appropriate vocational school, in order to obtain the better learning outcomes.

    Currently there are few validated metrics for predicting surgical skill among otolaryngology residency applicants. To determine whether manual dexterity aptitude testing in the form of soap carving during otolaryngology residency interviews at Kaiser Permanente Medical Center Oakland predicts surgical skill at the time of graduation from otolaryngology residency programs. This study was conducted to determine how applicants with the best and worst soap carvings compared at the time of graduation with respect to various metrics including visuospatial ability and manual dexterity. Over the last 25 years, applicants to the residency program at Kaiser Permanente Oakland were required to carve soap during their residency interview. The 3 best and 3 worst soap carvings from 1990 through 2006 were determined. Of the individuals who carved those soaps, 62 qualified for the study and matriculated into otolaryngology residency programs. Surveys were sent to the 62 individuals' residency programs to evaluate those individuals on a 5-point Likert scale in various categories as well as to rank those individuals as being in the top 50% or bottom 50% of their graduating class. All else being equal, we hypothesized that applicants who had the manual dexterity and visuospatial skills to accurately carve a bar of soap would more likely possess the skills necessary to become a good surgeon. There was no difference between individuals with the best soap carvings and those with the worst soap carvings in all categories: cognitive knowledge, visuospatial ability, manual dexterity, decision making, and overall score (P > .10 for all categories). There was a 95% response rate, with 35 of 37 residency programs responding and 59 of 62 surveys returned. Manual dexterity aptitude testing in the form of soap carving does not appear to correlate with surgical skill at the time of graduation. Further studies need to be conducted to determine the role of manual dexterity and visuospatial

    To determine if visuospatial perception (VSP) testing is correlated to simulated or intraoperative surgical performance as rated by the American College of Graduate Medical Education (ACGME) milestones. Classification II-2 SETTING: Two academic training institutions PARTICIPANTS: 41 residents, including 19 Brigham and Women's Hospital and 22 Mayo Clinic residents from three different specialties (OBGYN, general surgery, urology). Participants underwent three different tests: visuospatial perception testing (VSP), Fundamentals of Laparoscopic Surgery (FLS®) peg transfer, and DaVinci robotic simulation peg transfer. Surgical grading from the ACGME milestones tool was obtained for each participant. Demographic and subject background information was also collected including specialty, year of training, prior experience with simulated skills, and surgical interest. Standard statistical analysis using Student's t test were performed, and correlations were determined using adjusted linear regression models. In univariate analysis, BWH and Mayo training programs differed in both times and overall scores for both FLS® peg transfer and DaVinci robotic simulation peg transfer (p<0.05 for all). Additionally, type of residency training impacted time and overall score on robotic peg transfer. Familiarity with tasks correlated with higher score and faster task completion (p= 0.05 for all except VSP score). There was no difference in VSP scores by program, specialty, or year of training. In adjusted linear regression modeling, VSP testing was correlated only to robotic peg transfer skills (average time p=0.006, overall score p=0.001). Milestones did not correlate to either VSP or surgical simulation testing. VSP score was correlated with robotic simulation skills but not with FLS skills or ACGME milestones. This suggests that the ability of VSP score to predict competence differs between tasks. Therefore, further investigation is required into aptitude testing, especially prior

    Like in many other countries, few investigations have been carried out in Chile to measure the long-term effects of nutritional status at an early age on scholastic achievement in a multicausal approach. The objectives of the present study were to describe the impact of nutritional, intellectual, family, educational and socio-economic variables at the onset of elementary school in 1987 that may affect achievement on the academic aptitude test (AAT) taken in 1998 at the end of high school, and to quantify the impact of these independent variables on the AAT. The present study comprises two cross-sectional stages: in 1987, a representative sample of 813 elementary school first-grader Chilean children from the Metropolitan Region was randomly chosen; in 1998, 12 years later, 632 school-age children were located and only 351 of them graduated from high school and, from these, 260 students took the AAT. In 1987 nutritional status was assessed through anthropometric parameters, intellectual ability by the Raven's Progressive Matrices Test, scholastic achievement through Spanish language and mathematics tests, and socio-economic status using Graffar's modified scale; family variables were also recorded. Maternal schooling, scholastic achievement, intellectual ability and head circumference-for-age z-score (anthropometric indicator of both nutritional background and brain development) all in 1987 were the independent variables with the greatest explanatory power for AAT variance in 1998 (r2 0.402). These results provide a foundation to identify the risk factors at an early age that affect AAT scores and should be useful to improve nutritional and educational policies.

    Application to otolaryngology-head and neck surgery residency is highly competitive, and the interview process strives to select qualified applicants with a high aptitude for the specialty. Commonly employed criteria for applicant selection have failed to show correlation with proficiency during residency training. We evaluate the correlation between the results of a surgical aptitude test administered to otolaryngology resident applicants and their performance during residency. Retrospective study at an academic otolaryngology-head and neck surgery residency program. Between 2007 and 2013, 224 resident applicants participated in a previously described surgical aptitude test administered at a microvascular surgical station. The composite score and attitudinal scores for 24 consecutive residents who matched at our institution were recorded, and their residency performance was analyzed by faculty survey on a five-point scale. The composite and attitudinal scores were analyzed for correlation with residency performance score by regression analysis. Twenty-four residents were evaluated for overall quality as a clinician by eight faculty members who were blinded to the results of surgical aptitude testing. The results of these surveys showed good inter-rater reliability. Both the overall aptitude test scores and the subset attitudinal score showed reliability in predicting performance during residency training. The goal of the residency selection process is to evaluate the candidate's potential for success in residency and beyond. The results of this study suggest that a simple-to-administer clinical skills test may have predictive value for success in residency and clinician quality. 4. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

    2012-12-01

    Variation at the myostatin (MSTN) gene locus has been shown to influence racing phenotypes in Thoroughbred horses, and in particular, early skeletal muscle development and the aptitude for racing at short distances. Specifically, a single nucleotide polymorphism (SNP) in the first intron of MSTN (g.66493737C/T) is highly predictive of best race distance among Flat racing Thoroughbreds: homozygous C/C horses are best suited to short distance races, heterozygous C/T horses are best suited to middle distance races, and homozygous T/T horses are best suited to longer distance races. Patent applications for this gene marker association, and other linked markers, have been filed. The information contained within the patent applications is exclusively licensed to the commercial biotechnology company Equinome Ltd, which provides a DNA-based test to the international Thoroughbred horse racing and breeding industry. The application of this information in the industry enables informed decision making in breeding and racing and can be used to assist selection to accelerate the rate of change of genetic types among distinct populations (Case Study 1) and within individual breeding operations (Case Study 2).

  10. Newton and scholastic philosophy.

    Science.gov (United States)

    Levitin, Dmitri

    2016-03-01

    This article examines Isaac Newton's engagement with scholastic natural philosophy. In doing so, it makes two major historiographical interventions. First of all, the recent claim that Newton's use of the concepts of analysis and synthesis was derived from the Aristotelian regressus tradition is challenged on the basis of bibliographical, palaeographical and intellectual evidence. Consequently, a new, contextual explanation is offered for Newton's use of these concepts. Second, it will be shown that some of Newton's most famous pronouncements - from the General Scholium appended to the second edition of the Principia (1713) and from elsewhere - are simply incomprehensible without an understanding of specific scholastic terminology and its later reception, and that this impacts in quite significant ways on how we understand Newton's natural philosophy more generally. Contrary to the recent historiographical near-consensus, Newton did not hold an elaborate metaphysics, and his seemingly 'metaphysical' statements were in fact anti-scholastic polemical salvoes. The whole investigation will permit us a brief reconsideration of the relationship between the self-proclaimed 'new' natural philosophy and its scholastic predecessors.

  11. Results of the ESA study on psychological selection of astronaut applicants for Columbus missions I: Aptitude testing

    Science.gov (United States)

    Fassbender, Christoph; Goeters, Klaus-Martin

    European participation in the Space Station Freedom brought about new challenges for the psychological selection of astronaut candidates, particularly in respect to specific demands of long duration space flights. For this reason existing selection criteria and methods were reassessed. On these grounds a study was undertaken applying a unique composition of aptitude tests to a group of 97 ESA scientists and engineers who are highly comparable to the expected astronaut applicants with respect to age and education. The tests assessed operational aptitudes such as logical reasoning, memory function, perception, spatial orientation, attention, psychomotor function, and multiple task capacity. The study goals were: 1) Verification of psychometric qualities and applicability of tests in a normative group; 2) Search for culture-fair tests by which multi-national groups can be examined; 3) Identification of test methods which consider general and special operational demands of long duration space flights. Based on the empirical findings a test battery was arranged for use in the selection of ESA astronaut applicants. Results showed that 16 out of the 18 employed tests have good psychometric qualities and differentiate reliably in the special group of testees. The meta structure of the test battery as described by a factorial analysis is presented. Applicability of tests was generally high. Tests were culture-fair, however, a relation between English language skills and test results was identified. Since most item material was language-free, this was explained with the importance of English language skills for the understanding of test instructions. Solutions to this effect are suggested.

Subjects included 122 and 385 applicants for, respectively, early and regular admission to a medical school in Korea. The early admission examination was conducted in October 2007, and the regular admission examination was conducted in January 2008. The analysis of early admission data revealed significant F values for the mathematics/science type of essay (51.64; Pgrade point average (10.66; P=0.0014). The analysis of regular admission data revealed the following F values: 28.81 (Pgrade point average, 27.47 (P<0.0001) for college scholastic ability test, 10.67 (P=0.0012) for the essay, and 216.74 (P<0.0001) for the mathematics/science type of essay. Since the mathematics/science type of essay had a strong effect on acceptance, an emphasis on this requirement and exclusion of other kinds of essays would be effective in subsequent entrance examinations for this premed course.

    The visual spatial localization ability of geodesy and cartography - employers and of the pupils trained for the mentioned profession has been examined. The examination has been based on work duration and the time of its performance. A correlation between the localization ability and the precision of the hand - movements required in everyday work has been proven. The better the movement precision, the more efficient the visual spatial localization. The length of work has not been significant. The test concerned appeared to be highly useful in geodesy for qualifying workers for the posts requiring good hands efficiency.

  1. Construct-level predictive validity of educational attainment and intellectual aptitude tests in medical student selection: meta-regression of six UK longitudinal studies

    Science.gov (United States)

    2013-01-01

    Background Measures used for medical student selection should predict future performance during training. A problem for any selection study is that predictor-outcome correlations are known only in those who have been selected, whereas selectors need to know how measures would predict in the entire pool of applicants. That problem of interpretation can be solved by calculating construct-level predictive validity, an estimate of true predictor-outcome correlation across the range of applicant abilities. Methods Construct-level predictive validities were calculated in six cohort studies of medical student selection and training (student entry, 1972 to 2009) for a range of predictors, including A-levels, General Certificates of Secondary Education (GCSEs)/O-levels, and aptitude tests (AH5 and UK Clinical Aptitude Test (UKCAT)). Outcomes included undergraduate basic medical science and finals assessments, as well as postgraduate measures of Membership of the Royal Colleges of Physicians of the United Kingdom (MRCP(UK)) performance and entry in the Specialist Register. Construct-level predictive validity was calculated with the method of Hunter, Schmidt and Le (2006), adapted to correct for right-censorship of examination results due to grade inflation. Results Meta-regression analyzed 57 separate predictor-outcome correlations (POCs) and construct-level predictive validities (CLPVs). Mean CLPVs are substantially higher (.450) than mean POCs (.171). Mean CLPVs for first-year examinations, were high for A-levels (.809; CI: .501 to .935), and lower for GCSEs/O-levels (.332; CI: .024 to .583) and UKCAT (mean = .245; CI: .207 to .276). A-levels had higher CLPVs for all undergraduate and postgraduate assessments than did GCSEs/O-levels and intellectual aptitude tests. CLPVs of educational attainment measures decline somewhat during training, but continue to predict postgraduate performance. Intellectual aptitude tests have lower CLPVs than A-levels or GCSEs

    The present study aims at recognizing the social influence, study habits and health factors affecting scholastic performances of adolescents and to compare these factors among the adolescents between two categories of school. A total of 1230 adolescents (13-18 yrs) were screened. Data was collected by personal interview, using the teenage screening questionnaire, Trivandrum, between May 2004 and November 2005. A total 615 students from corporation and private schools were studied. 39.76% (489) were high achievers, 13.5% (166) were low achievers with p poor study habits and social factors were increased in low achievers of corporation schools. On multivariate analysis, the predictor variables for poor scholastic performance were adolescent having refractory error, not having help for study at home, not doing home work regularly, not solving question bank papers and reading only before examinations. It is feasible and worthwhile to identify the determinants of scholastic performance and plan intervention strategies at each school. The results of this study highlight the importance of implementing newer strategies, focusing on strict study patterns and creating the conducive school and home environment for study, so as to achieve better scholastic performances.

    We aimed to examine the effects of reading difficulties on scholastic self-evaluation and mental health in elementary school students. Following guidelines for diagnosing reading disorders in elementary school students, we administered reading test batteries consisting of single sounds, single words, and single sentences to 41 fifth-grade elementary school students in Japan. The students' levels of scholastic self-evaluation, self-esteem, and depressive symptoms were assessed using self-rating questionnaires. By evaluating students' reading speed and the number of reading errors they made, we found that six students (14.6%) had reading difficulties (RD group) as per the guidelines for diagnosing reading disorders. The scholastic self-evaluation scores of this RD group were significantly lower than that of the non-RD group. No significant differences were found between the groups on self-esteem or depressive symptoms scores, which we considered to be indicators of mental health, Speed in reading single sounds and single words, and the number of reading errors in reading single sounds had significant negative correlations with scholastic self-evaluation scores. We found that reading difficulties might result in decreased scholastic self-evaluation in elementary school students; however, reading difficulties did not directly influence self-esteem or depression.

    This study examined the vocational aptitude and interest scores of 326 inpatients at a large urban psychiatric hospital. The inpatient group performed significantly below the adult normative mean on eight of nine General Aptitude Test Battery (GATB) aptitude measures; the single exception was Verbal Aptitude. Further, GATB aptitude scores (adjusted for age and education) were significantly lower for patients who were receiving (N = 210) psychotropic medication than for patients who were not receiving (N = 114) psychotropic medication, again with the exception of Verbal Aptitude. Differentiation of patients into subsamples who were receiving particular drugs or drug combinations indicated that phenothiazines in combination with Anti-Parkinsonians were associated with the poorest GATB performances. Interestingly, self-reported vocational interests were not related in any systematic fashion to receiving medication. A variety of explanations that may account for these findings, including drug side-effects and severity or type of psychiatric disorder, were investigated. Implications for vocational counselors were discussed.

  12. Scholastic performance and functional connectivity of brain networks in children.

    Directory of Open Access Journals (Sweden)

    Laura Chaddock-Heyman

    Full Text Available One of the keys to understanding scholastic success is to determine the neural processes involved in school performance. The present study is the first to use a whole-brain connectivity approach to explore whether functional connectivity of resting state brain networks is associated with scholastic performance in seventy-four 7- to 9-year-old children. We demonstrate that children with higher scholastic performance across reading, math and language have more integrated and interconnected resting state networks, specifically the default mode network, salience network, and frontoparietal network. To add specificity, core regions of the dorsal attention and visual networks did not relate to scholastic performance. The results extend the cognitive role of brain networks in children as well as suggest the importance of network connectivity in scholastic success.

  13. Interest in mathematics and science among students having high mathematics aptitude

    Science.gov (United States)

    Ely, Jane Alice

    The study investigates why men and women differ in their interest in mathematics and science and in the pursuit of careers in mathematics and science. The most persistent gender differential in educational standard testing is the scores in mathematics achievement. The mean Scholastic Aptitude Test (Mathematics) scores for women are consistently below that of men by about 40 points. One result of this gender differential in mathematics is that few women entertain a career requiring a robust knowledge of higher mathematics (i.e. engineering, computing, or the physical sciences). A large body of literature has been written attempting to explain why this is happening. Biological, cultural, structural and psychological explanations have been suggested and empirically examined. Controlling for mathematical ability is one method of sorting out these explanations. Eliminating mathematical ability as a factor, this dissertation reports the results of a study of men and women college students who all had high mathematics ability. Thus, any differences we found among them would have to be a result of other variables. Using a Mathematics Placement Exam and the SAT-M, forty-two students (12 males and 30 females) with high scores in both were interviewed. Student were asked about their experiences in high school and college mathematics, their career choices, and their attitudes toward mathematics. The findings, that there were no gender differences in the course selection, attitudes towards mathematics, and career choice, differed from my initial expectations. This negative finding suggests that women with high ability in mathematics are just as likely as men to pursue interests in mathematics and related courses in college and in selecting careers.

    Recent research has shown that the morphology of certain brain regions may indeed correlate with a number of cognitive skills such as musicality or language ability. The main aim of the present study was to explore the extent to which foreign language aptitude, in particular phonetic coding ability, is influenced by the morphology of Heschl's gyrus (HG; auditory cortex), working memory capacity, and musical ability. In this study, the auditory cortices of German-speaking individuals ( N = 30; 13 males/17 females; aged 20-40 years) with high and low scores in a number of language aptitude tests were compared. The subjects' language aptitude was measured by three different tests, namely a Hindi speech imitation task (phonetic coding ability), an English pronunciation assessment, and the Modern Language Aptitude Test (MLAT). Furthermore, working memory capacity and musical ability were assessed to reveal their relationship with foreign language aptitude. On the behavioral level, significant correlations were found between phonetic coding ability, English pronunciation skills, musical experience, and language aptitude as measured by the MLAT. Parts of all three tests measuring language aptitude correlated positively and significantly with each other, supporting their validity for measuring components of language aptitude. Remarkably, the number of instruments played by subjects showed significant correlations with all language aptitude measures and musicality, whereas, the number of foreign languages did not show any correlations. With regard to the neuroanatomy of auditory cortex, adults with very high scores in the Hindi testing and the musicality test (AMMA) demonstrated a clear predominance of complete posterior HG duplications in the right hemisphere. This may reignite the discussion of the importance of the right hemisphere for language processing, especially when linked or common resources are involved, such as the inter-dependency between phonetic and musical

  20. Gender differences in the causal relation between adolescents' maths self-concept and scholastic performance

    Full Text Available Mathematics is a core subject in every school curriculum and it is strongly correlated with maths self-concept, which is defined as the subjective feelings and beliefs about one's competence in maths. In general, boys tend to report higher maths self-concept than girls, but the difference between boys and girls' maths scholastic performance is low or even inexistent. Some authors maintain that academic self-concept can play an important role as a motivational variable, promoting self-confidence and investment in the learning process. This study examined the causal relations between maths self-concept and maths scholastic performance in four cohorts of boys and girls within a three-wave longitudinal study. The first two cohorts were composed of 187 girls and 139 boys attending grades 7 and 8 at Time 1 and the third and fourth cohorts were composed of 167 girls and 123 boys attending grades 9 and 10 at Time 1. Structural Equation Modelling was used to test the fit of several models of causal relations. The results revealed that for the first two cohorts the best models were reciprocal and skill-development for both boys and girls. However, for the older students, a reciprocal model gave a best fit for the boys, but for the girls there was only one significant effect from maths self-concept to maths scholastic performance. Results are discussed on the basis of gender-related differential learning expectancies.

    Automatic item generation (AIG) is a broad class of methods that are being developed to address psychometric issues arising from internet and computer-based testing. In general, issues emphasize efficiency, validity, and diagnostic usefulness of large scale mental testing. Rapid prominence of AIG methods and their implicit perspective on mental testing is bringing painful scrutiny to many sacred psychometric assumptions. This report reviews basic AIG ideas, then presents conceptual foundations, image model development, and operational application to artistic judgment aptitude testing.

  2. A Theory of Sex Differences in Technical Aptitude and Some Supporting Evidence.

    Schmidt, Frank L

    2011-11-01

    In this article, I present a theory that explains the origin of sex differences in technical aptitudes. The theory takes as proven that there are no sex differences in general mental ability (GMA), and it postulates that sex differences in technical aptitude (TA) stem from differences in experience in technical areas, which is in turn based on sex differences in technical interests. Using a large data set, I tested and found support for four predictions made by this theory: (a) the construct level correlation between technical aptitude and GMA is larger for females than males, (b) the observed and true score variability of technical aptitude is greater among males than females, (c) at every level of GMA females have lower levels of technical aptitude, and (d) technical aptitude measures used as estimates of GMA for decision purposes would result in underestimation of GMA levels for girls and women. Given that GMA carries the weight of prediction of job performance, the support found for this last prediction suggests that, for many jobs, technical aptitude tests may underpredict the job performance of female applicants and employees. Future research should examine this question. © Association for Psychological Science 2011.

  3. Evaluation of saddle and driving aptitudes in Monterufoli pony

    Full Text Available The Monterufoli pony is an endangered Tuscan breed. In the 80’s began a project for the conservation of the breed and at present there are roughly 200 individuals. The equine was once utilized for saddle and driving and this study deals with the training for these two aptitudes. The mor- phologic type of the pony seems suited for saddle, in particular for children and beginners, and driving. The ponies showed developed chest, strong legs with short shanks: all these characters were useful for trot and driving. In this trial 3-4 years old never tamed Monterufoli ponies were opportunely choose and subsequently trained for saddle and driving. The ponies were submitted to the “aptitude test” for the two aptitudes and the results were good both for practical and character sides. The marks for sad- dle and driving were 8.16 and 8.06 respectively. Also the 3 ponies showed good results for the Aptitude Index: 7.60, 7.87 and 7.89. The results of the trial showed the excellent ability of the Monterufoli pony for saddle and driving. The good results of the test are important for the diffusion of the breed in the territory and in particular in horse centres and in equestrian tourism sites.

  4. Personality factors as predictors of foreign language aptitude

    2011-12-01

    Full Text Available The study addresses a problem which is inadequately investigated in second language acquisition research, that is, personality predictors of foreign language aptitude. Specifically, it focuses on the Five Factor model which includes Openness to Experience, Conscientiousness, Extraversion, Agreeableness and Neuroticism (Costa & McCrae, 1992 as traits differentiating gifted and nongifted foreign language learners and predicting results of foreign language aptitude tests. Although contemporary researchers generally agree that affect is an important variable in second language acquisition, most empirical studies demonstrate that personality factors are weakly correlated with cognitive abilities and that their contribution to the ultimate attainment is minor (cf. Robinson & Ellis, 2008. On the other hand, these factors constitute an integral part of cognitive ability development (cf. Dörnyei, 2009; therefore, neglecting them in research on foreign language aptitude would be unjustified. The following study is an attempt to analyze the Five Factors in two groups of learners: gifted and nongifted. In order to answer the question as to which and to what extent personality factors have a predictive effect on foreign language aptitude, the results were subjected to a multiple regression analysis. The findings of the study are presented and discussed in a wider context of research on cognitive abilities.

    Most UK medical schools use aptitude tests during student selection, but large-scale studies of predictive validity are rare. This study assesses the United Kingdom Clinical Aptitude Test (UKCAT), and its four sub-scales, along with measures of educational attainment, individual and contextual socio-economic background factors, as predictors of performance in the first year of medical school training. A prospective study of 4,811 students in 12 UK medical schools taking the UKCAT from 2006 to 2008 as a part of the medical school application, for whom first year medical school examination results were available in 2008 to 2010. UKCAT scores and educational attainment measures (General Certificate of Education (GCE): A-levels, and so on; or Scottish Qualifications Authority (SQA): Scottish Highers, and so on) were significant predictors of outcome. UKCAT predicted outcome better in female students than male students, and better in mature than non-mature students. Incremental validity of UKCAT taking educational attainment into account was significant, but small. Medical school performance was also affected by sex (male students performing less well), ethnicity (non-White students performing less well), and a contextual measure of secondary schooling, students from secondary schools with greater average attainment at A-level (irrespective of public or private sector) performing less well. Multilevel modeling showed no differences between medical schools in predictive ability of the various measures. UKCAT sub-scales predicted similarly, except that Verbal Reasoning correlated positively with performance on Theory examinations, but negatively with Skills assessments. This collaborative study in 12 medical schools shows the power of large-scale studies of medical education for answering previously unanswerable but important questions about medical student selection, education and training. UKCAT has predictive validity as a predictor of medical school outcome

  14. Language aptitude: Desirable trait or acquirable attribute?

    Directory of Open Access Journals (Sweden)

    2017-03-01

    Full Text Available The traditional definition of language aptitude sees it as “an individual’s initial state of readiness and capacity for learning a foreign language, and probable facility in doing so given the presence of motivation and opportunity” (Carroll, 1981, p. 86. This conception portrays language aptitude as a trait, in the sense of exhibiting stability over long periods of time and being immune to training. The trait view of language aptitude tends towards the notion that it is innate, and indeed language aptitude has often been associated with the popular notion of a “gift for languages” (cf. Rosenthal, 1996, p. 59. The view of language aptitude as an innate trait has, however, long been questioned (see e.g., Neufeld, 1978. Recently, this questioning has intensified (see Singleton, 2014, especially since the development of a widespread consensus that working memory needs to be recognized as an important component of language aptitude (see Wen, 2016. Working memory was also once thought of as a trait, but is now recognized as susceptible to the influence of experience and instruction (see e.g., Williams, 2012. The present paper will track the trajectory of the above theoretical discussion and will explore the implications of the stage it has now reached.

    The aim of this study was to investigate the influence of a school-based intervention with a tripling of physical education (PE) lessons from two (90 minutes) to six lessons per week (270 minutes) on scholastic performance. This study is part of the CHAMPS study-DK, a quasi-experimental study that began in 2008. The intervention group consisted of six schools, and the control group consisted of four matched schools (mean age at baseline=8.4 years, kindergarten class fourth grade). Academic performance was extracted from the national test system from 2010 to 2014 (Math and Danish were measured at third and sixth, and second, fourth and sixth grades, respectively). Participants included 1888 students participating in at least one scholastic performance test. Linear mixed models were applied to test for differences between groups and adjusted for known confounders. No significant differences were observed between groups in the academic performance tests (control group reference); Danish second grade β=-1.34 (95% CI -9.90, 7.22), fourth grade β=0.22 (95% CI -6.12, 6.56), sixth grade β=1.03 (95% CI -5.02, 7.08), and all grades combined β=0.28 (95% CI -5.74, 6.31) and Math third grade β=-2.87 (95% CI -9.65, 3.90), sixth grade β=0.99 (95% CI -7.36, 9.34) and combined β=-1.20 (95% CI -8.10, 5.71). In conclusion, no significant differences were observed between intervention and control schools for scholastic performance. Importantly, there were no negative effects of additional PE on scholastic outcomes, despite more PE and longer school days for intervention children. © 2017 The Authors Scandinavian Journal of Medicine & Science In Sports Published by John Wiley & Sons Ltd.

    The aim of this study is to assess the relationship between video gaming habits and elementary school students' academic performance. More specifically, we seek to examine the usefulness of a distinction between addiction and high engagement and assess the predictive validity of these concepts in the context of scholastic achievement. Three hundred thirty-three children ages 8 to 12 years from two primary schools in Singapore were selected to participate in this study. A survey utilizing Danforth's Engagement-Addiction (II) scale and questions from DSM-IV was used to collect information from the schoolchildren, while their grades were obtained directly from their teachers. The findings indicate that addiction tendencies are consistently negatively related to scholastic performance, while no such relationship is found for either time spent playing games or for video game engagement. The implications of these findings are discussed.

    Full Text Available With the aim of gaining insight into literary text comprehension and the linkage between that comprehension and scholastic achievement during the first years of schooling, a research was conducted on the sample of 152 third and fourth grade pupils from one urban and one rural school. After having read silently a selected atypical excerpt from one literary text, interviewed pupils filled out the questionnaire constructed for the purposes of this research starting from the 11 categories of text comprehension singled out based on the theory of comprehension and interpretation of literary text and the current curriculum. In the first part of the research we applied the Children's orientation scale by Malka Margalit, and school marks were used as a measurement of scholastic achievement. Research results point out that, among other things, inferring on the basis of what has been read poses the greatest difficulty for third and fourth graders, that is, that almost three quarters of them are not capable of determining the meaning of some representative sentences from that text. In the positive sense, it was established that almost three quarters of them perceive beautiful poetic expressions and about 80% of them can at least to a certain extent recognize character descriptions, emotional situations and moods, that is, discover significant facts. Answers to the questions regarding the majority of categories of text comprehension are significantly correlated with scholastic achievement. As expected, the highest correlations between the measures on text comprehension categories are with the marks in native (Serbian language. Partial correlations between the measures on certain categories of text comprehension and measurements of scholastic achievement (excluding the influence of feeling of coherence are not significantly different from bivariate. Based on the obtained data, authors conclude that the utilized system of categories can be a useful tool for

    Current methods of assessing candidates for medical specialties that involve laparoscopic skills suffer from a lack of instruments to assess the ability to work in a minimally invasive surgery environment. A meta-analysis was conducted to investigate whether aptitude assessment can be used to predict variability in the acquisition and performance of laparoscopic skills. PubMed, PsycINFO and Google Scholar were searched to November 2014 for published and unpublished studies reporting the measurement of a form of aptitude for laparoscopic skills. The quality of studies was assessed with QUADAS-2. Summary correlations were calculated using a random-effects model. Thirty-four studies were found to be eligible for inclusion; six of these studies used an operating room performance measurement. Laparoscopic skills correlated significantly with visual-spatial ability (r = 0.32, 95% confidence interval [CI] 0.25-0.39; p < 0.001), perceptual ability (r = 0.31, 95% CI 0.22-0.39; p < 0.001), psychomotor ability (r = 0.26, 95% CI 0.10-0.40; p = 0.003) and simulator-based assessment of aptitude (r = 0.64, 95% CI 0.52-0.73; p < 0.001). Three-dimensional dynamic visual-spatial ability showed a significantly higher correlation than intrinsic static visual-spatial ability (p = 0.024). In general, aptitude assessments are associated with laparoscopic skill level. Simulator-based assessment of aptitude appears to have the potential to represent a job sample and to enable the assessment of all forms of aptitude for laparoscopic surgery at once. A laparoscopy aptitude test can be a valuable additional tool in the assessment of candidates for medical specialties that require laparoscopic skills. © 2016 John Wiley & Sons Ltd.

Aptitude Treatment Interaction (ATI can serve individual student differences by adjusting treatment or learning method with students' abilities. The use of this model was emphasizing to create small groups of students that have achievement alike. Students with have low academic achievement based on test results and teacher interview will be grouped into one group and will be given preferential treatment by tutoring intensity rather than the group of high academic achievement. Subjects of this research were students of class VII.3 SMP Negeri 6 Parepare which is consist of 25 students. This research was conducted in two cycles. The procedure of this research involved four phases: (1 planning, (2 Implementation of action, (3 observation, (4 Reflection. The data collection was done by observation, tests, and questionnaires for each cycle after giving treatment through learning model Aptitude Treatment Interaction (ATI. Data collected were analyzed using quantitative and qualitative analysis. The results of this research indicate that the Aptitude Treatment Interaction (ATI can be an alternative method to improve learning motivation of low achievement students. The results of this research also showed that the Aptitude Treatment Interaction (ATI can be an alternative to problem-solving in the classroom, especially for low achievement students.

    It has been established that there is an interaction between audition and vision in the appraisal of our living environment, and that this appraisal is influenced by personal factors. Here, we test the hypothesis that audiovisual aptitude influences appraisal of our sonic and visual environment. To measure audiovisual aptitude, an auditory deviant detection experiment was conducted in an ecologically valid and complex context. This experiment allows us to distinguish between accurate and less accurate listeners. Additionally, it allows to distinguish between participants that are easily visually distracted and those who are not. To do so, two previously conducted laboratory experiments were re-analyzed. The first experiment focuses on self-reported noise annoyance in a living room context, whereas the second experiment focuses on the perceived pleasantness of using outdoor public spaces. In the first experiment, the influence of visibility of vegetation on self-reported noise annoyance was modified by audiovisual aptitude. In the second one, it was found that the overall appraisal of walking across a bridge is influenced by audiovisual aptitude, in particular when a visually intrusive noise barrier is used to reduce highway traffic noise levels. We conclude that audiovisual aptitude may affect the appraisal of the living environment.

    Studies of neurodevelopmental outcomes in offspring exposed to MeHg from maternal consumption of fish have primarily measured cognitive abilities. Reported associations have been subtle and in both adverse and beneficial directions. Changes in functional outcomes such as school achievement and behavior in exposed children and adolescents have not been examined. We undertook an assessment of school success of children in the Seychelles Child Development Study (SCDS) main cohort to determine if there were any associations with either prenatal or recent postnatal MeHg exposure. The primary endpoints were Seychelles nationally standardized end-of-year examinations given when the cohort children were 9 and 17 years of age. A subgroup (n=215) from the main cohort was also examined at 9 years of age using a regional achievement test called SACMEQ. Prenatal MeHg exposure was 6.8 ppm in maternal hair; recent postnatal exposure was 6.09 ppm at 9 years and 8.0 ppm at 17 years, measured in child hair. Multiple linear regression analyses showed no pattern of associations between prenatal or postnatal exposure, and either the 9- or 17-year end-of-year examination scores. For the subgroup of 215 subjects who participated in the SACMEQ test, there were significant adverse associations between examination scores and postnatal exposure, but only for males. The average postnatal exposure level in child hair for this subgroup was significantly higher than for the overall cohort. These results are consistent with our earlier studies and support the interpretation that prenatal MeHg exposure at dosages achieved by mothers consuming a diet high in fish are not associated with adverse educational measures of scholastic achievement. The adverse association of educational measures with postnatal exposure in males is intriguing, but will need to be confirmed by further studies examining factors that influence scholastic achievement.

    Full Text Available Background & objectives: Several studies have been conducted in India to determine the prevalence of learning disabilities in school children which has been reported to be 3-10 per cent among students population. The present study was conducted to find out prevalence of specific developmental disorder of scholastic skills in students of classes VII to XII and to find out feasibility of screening tool in Chandigarh, India. Methods: A cross-sectional study on school students was carried out in two phases. The students were drawn from classes VII to XII from 10 schools of Chandigarh, India. Details of academic performance of all the students was taken, subjectively from class teachers and objectively from the marks obtained in the last academic session. In phase I, 2402 students were assessed. In phase II, 108 students were randomly selected for evaluation for assessing sensitivity and specificity of screening proforma for teachers. A total of 124 students from phase I and all students in phase II were assessed in detail. Tests of intelligence (Malin′s Intelligence Scale for Indian Children and Standard Progressive Matrices, and NIMHANS Index for specific learning disability (SLD battery were administered. Results: A total of 38 students were found to be having specific developmental disorder of scholastic skills in phase I, that gave a prevalence of 1.58 per cent. Majority had mixed type of errors on SLD battery. There were more boys diagnosed with specific learning disability. Teacher′s screening instrument had high sensitivity (90.385 and specificity (94.68. Interpretation & conclusions: The findings of our study conducted in community, showed that specific learning disability was not identified even till later age. The screening instrument thus could be used by teachers to suspect students with specific learning disability.

    Artistic creativity forms the basis of music culture and music industry. Composing, improvising and arranging music are complex creative functions of the human brain, which biological value remains unknown. We hypothesized that practicing music is social communication that needs musical aptitude and even creativity in music. In order to understand the neurobiological basis of music in human evolution and communication we analyzed polymorphisms of the arginine vasopressin receptor 1A (AVPR1A), serotonin transporter (SLC6A4), catecol-O-methyltranferase (COMT), dopamin receptor D2 (DRD2) and tyrosine hydroxylase 1 (TPH1), genes associated with social bonding and cognitive functions in 19 Finnish families (n = 343 members) with professional musicians and/or active amateurs. All family members were tested for musical aptitude using the auditory structuring ability test (Karma Music test; KMT) and Carl Seashores tests for pitch (SP) and for time (ST). Data on creativity in music (composing, improvising and/or arranging music) was surveyed using a web-based questionnaire. Here we show for the first time that creative functions in music have a strong genetic component (h2 = .84; composing h2 = .40; arranging h2 = .46; improvising h2 = .62) in Finnish multigenerational families. We also show that high music test scores are significantly associated with creative functions in music (pmusic test scores (COMB) (p = 0.0056; corrected p = 0.0006). AVPR1A haplotype AVR+RS1 further suggested a positive association with ST (p = 0.0038; corrected p = 0.00184) and COMB (p = 0.0083; corrected p = 0.0040) using haplotype-based association test HBAT. The results suggest that the neurobiology of music perception and production is likely to be related to the pathways affecting intrinsic attachment behavior. PMID:19461995

    There are 180,000 new Diabetes Mellitus cases in Mexico each year (1). This chronic, complex and multifactor disease requires an adequate nutritional management plan to be prescribed by family physicians. They should be trained to identify the potential difficulties in the patient's dietary schedule and orientate their management from an integrative point of view. The purpose of this study was to detect and measure family physician's clinical aptitudes for the nutritional management of Type 2 diabetes, in a representative family physician's sample from five Family Medicine Units of the Mexican Institute of Social Security in Guadalajara, Jalisco, Mexico. A structured and validated instrument was applied to 117 physicians from a total of 450 in Guadalajara, Jalisco. The main study variable was clinical aptitude for nutritional management of Type 2 diabetes. Aptitude levels were defined by an ordinal scale and related to the other variables using the median, Mann-Whitney's U test and Kruskal Wallis (KW) test. Global results showed a median of 30 points that relates to a low and a very low aptitude level for the 72% of physicians without statistical significance (KW: p>0.05) with the rest of variables. These results reflect family physician's difficulties to orientate the nutritional management of Type 2 diabetes, as well as the lack of work environments that facilitate case reflection and formative educational strategies.

    This study aimed to prospectively investigate the scholastic factors related to illicit drug misuse (IDM) and the initiation of IDM among older adolescents from Bosnia and Herzegovina. This 2-year prospective study included 436 participants (202 females), who were an average of 16 years old at the beginning of the study (baseline). The participants were tested at baseline and follow-up (20 months later). The predictors included variables of scholastic-achievement (grade point average, school absences, unexcused absences and behavioral grade). The criteria were: (i) IDM at baseline; (ii) IDM at follow-up; and (iii) initiation of IDM over the study course. Results : Logistic regression indicated increased odds of IDM in adolescents who were more frequent absent from school (baseline: Odds Ratio (OR): 3.73, 95% Confidence Interval (CI): 2.12⁻6.57; follow-up: OR: 2.91, 95% CI: 1.90⁻4.65). The lower grade point average and more unexcused absences were evidenced for adolescents who consumed drugs on follow-up (OR: 1.67, 95% CI: 1.11⁻2.51; OR: 1.74, 95% CI: 1.30⁻2.32 for grade point average and unexcused absences, respectively). Initiation of IDM was predicted by frequent absences from school (OR: 2.2, 95% CI: 1.3⁻3.8), and lower behavioral grades (OR: 1.9, 95% CI: 1.2⁻3.3). The findings confirmed strong correlations between scholastic failure and IDM. Absences from school and lower behavioral grades at baseline were predictive of the initiation of IDM in older adolescents.

    The present paper reports the findings of a study of scholastic backwardness among five to eight year old school going children. 1535 children were screened by their class teachers, of which 10.23% were found to have scholastic backwardness. No gender differences were noticed. The rates of specific difficulties such as reading, writing and arithmetic were found to be 4.69%, 5.15% and 15.96% respectively. About 26% of the scholastically backward children were also found to have psychological disturbance. In addition, they most often came from families which could not afford basic amenities, had fathers with alcohol dependence, inconsistent disciplining and poor parental interaction. They also had more frequent school changes, tution attendence and fewer hobbies compared to the scholastically superior children.

    Fifty-four students were tested at specific time intervals over 10 years to determine best native language (NL) predictors of oral and written foreign language (FL) proficiency and FL aptitude. All participants completed two years of Spanish, French, or German. Each was administered measures of NL literacy, oral language, and cognitive ability in elementary school. A measure of FL aptitude was administered at the beginning of ninth grade and FL proficiency was evaluated at the end of the 10th grade. Among the variables, NL literacy measures were the best predictors of FL proficiency, and NL achievement and general (verbal) intelligence were strong predictors of FL aptitude. Results suggest that indices of NL literacy as early as first grade are related to FL proficiency and FL aptitude nine and 10 years later. Findings provide strong support for connections between L1 and L2 skills, and for speculation that "lower level" skills in phonological processing are important for written language development and oral proficiency in a FL.

    Full Text Available Abstract Background Attention Deficit/Hyperactivity Disorder (ADHD affects many children, adolescents, and adults and is associated with a number of impairments. Poor academic performance is related to ADHD in clinical samples. However, it is unclear to what extent core ADHD symptoms and scholastic impairment are related in non-referred school-aged children. Methods Data come from three population-based cohorts from Sweden, Denmark, and Finland, which are part of the Nordic Network on ADHD. The combined sample size was 13,087 children who were studied at ages 7–8 or 10–12 years. Teachers rated children on inattention and hyperactivity symptoms and reported children's scholastic performance on basic skills. Results There was a significant association in all cohorts between core ADHD symptoms and scholastic impairment in reading, writing, and mathematics. Particularly, inattention was related to a two to tenfold increase in scholastic impairment. Prevalence of hyperactivity symptoms was similar across the three cohorts, but inattention was lowest among children from the Finnish cohort, after stratification on living conditions. Conclusion These results extend previous reports of scholastic impairment among children with clinically diagnosed ADHD to non-referred population samples from three European countries. Surveillance policies should be implemented in school systems to catch children in need of behavioral or scholastic support early.

    Full Text Available Orientation: Details of applicants’ secondary education (incorporating subject choice could be a useful screening tool when processing large applicant pools. Here, the relationships between secondary education (incorporating subject choice and the reasoning and visual perceptual speed components of the Differential Aptitude Test are explored. Research purpose: The objective of the study was to determine whether type of secondary education (incorporating subject choice could be used as a substitute for reasoning (verbal and non-verbal and/or visual perceptual speed aptitudes in the selection of operators for an automotive plant in South Africa. Motivation for the study: The motivation for this study arose from the evident gap in academic literature as well as the selection needs of the automotive industry. Research design, approach and method: This research adopted a quantitative approach. It involved a non-probability convenience quota sample of 2463 work-seeking applicants for an automotive operator position in South Africa. Participants completed a biographical questionnaire and three subtests from the Differential Aptitude Test battery. The Chi-square test was used to determine the relationship between type of secondary education (incorporating subject choice and selected cognitive aptitudes. Main findings: The study’s findings revealed statistically and practically significant relationships between type of secondary education (incorporating subject choice, verbal reasoning, non-verbal reasoning and visual perceptual speed. Broad performance levels in the three aptitude subtests employed in this study were significantly associated with the type of matriculation certificate held by applicants. The findings specifically indicated that the secondary education types that included the subjects mathematics or both mathematics and science were associated with higher levels of performance in the three aptitudes.

  10. Schoolteachers' awareness about scholastic performance and nutritional status of Egyptian schoolchildren.

    Galal, Osman M; Ismail, Ibrahim; Gohar, Azza S; Foster, Zoë

    2005-06-01

    Malnutrition disorders affect more than 30% of schoolchildren in Egypt. This problem appears to be largely attributable to poor dietary quality and micronutrient deficiencies, such as iron and vitamin A. Inadequate nutrition intake has important implications because malnutrition has been shown to negatively affect the cognitive development of primary schoolchildren. This study assesses the awareness of schoolteachers about the impact of malnutrition on the scholastic performance of primary schoolchildren living in Egypt. Two focus group discussions were conducted with Egyptian schoolteachers from the Quena and Kharbia Governorates. The study indicates that schoolteachers consider low body weight and thinness as the primary signs of malnutrition. They do not prioritize malnutrition as a factor for poor scholastic performance. They also suggest that unhealthful eating habits, especially a lack of breakfast, negatively affect children's interaction with schoolteachers and their ability to excel in their studies. Schoolteachers endorse a more reliable and nutritionally valuable school-feeding program as a way to increase the scholastic performance of their students. The teachers advocate developing integrated programs between the Ministry of Education, the Ministry of Health and Population, teachers, children, and parents that provide nutrition education. A lack of awareness among teachers about the relationship of nutrition and cognitive function can lead to the misdiagnosis or delayed management of malnourished and scholastically challenged schoolchildren. This paper suggests that proper school-feeding programs and nutrition education programs, which integrate government ministries, teachers, children and parents, should be developed to improve the physical and cognitive health status of Egyptian schoolchildren.

    In this paper, we discuss various issues related to the concept of resilience, which is conventionally defined as a dynamic process allowing for a positive adaptation in a context of significant adversity. First, we try to draw the reader's attention to the importance of the concept of resilience in terms of public health. Second, we address the difficulty of measuring resilience in a relevant and operational manner. Third, we then address the question of whether resilience can be conceived only in the context of a confrontation with trauma, or whether its application can be relevant to the everyday nontraumatic adversity. In this regard, we introduce and define another coping strategy which is the Sense of Coherence (SOC). Fourth, we discuss the nature of resilience, that is to say, whether it should be considered as a personality trait or as an aptitude. We try to show that this problem arises from the difficulty to specify the emotional processes involved in resilience. Finally, we propose future research perspectives that should allow us to better understand the concept of resilience.

    When searching for genetic markers inherited together with musical aptitude, genes affecting inner ear development and brain function were identified. The alpha-synuclein gene (SNCA), located in the most significant linkage region of musical aptitude, was overexpressed when listening and performing music. The GATA-binding protein 2 gene (GATA2) was located in the best associated region of musical aptitude and regulates SNCA in dopaminergic neurons, thus linking DNA- and RNA-based studies of music-related traits together. In addition to SNCA, several other genes were linked to dopamine metabolism. Mutations in SNCA predispose to Lewy-body dementia and cause Parkinson disease in humans and affect song production in songbirds. Several other birdsong genes were found in transcriptome analysis, suggesting a common evolutionary background of sound perception and production in humans and songbirds. Regions of positive selection with musical aptitude contained genes affecting auditory perception, cognitive performance, memory, human language development, and song perception and production of songbirds. The data support the role of dopaminergic pathway and their link to the reward mechanism as a molecular determinant in positive selection of music. Integration of gene-level data from the literature across multiple species prioritized activity-dependent immediate early genes as candidate genes in musical aptitude and listening to and performing music. © 2018 New York Academy of Sciences.

    Full Text Available We contribute to the sociology of sport and gender literature with an ethnographic analysis of scholastic wrestling by observing the current climate of masculinity and gender. Our results suggest that it is necessary to understand men and sporting behavior within a broader framework of gender, not just masculinity, because the behavior of high school wrestlers fell along a gender continuum between an orthodox masculinity and femininity. Our exploration of the body, performance, and emotion practices of scholastic wrestlers gives credence to the current critiques of a hegemonic masculinity in men's sports. We show that gender is not dichotomous and that even in the highly masculinized sport of wrestling, feminine behavior by men is evident.

    Scholastic productivity has previously been shown to be positively associated with National Institute of Health (NIH) grants and industry funding. This study examines whether society, industry, or federal funding contributes toward academic productivity as measured by scholastic output of academic plastic surgeons. Institution Web sites were used to acquire academic attributes of full-time academic plastic surgeons. The Center for Medicare and Medicaid Services Open Payment database, NIH reporter, the Plastic Surgery Foundation (PSF), and American Association of Plastic Surgeons (AAPS) Web sites were accessed for funding and endowment details. Bibliometric data of each surgeon were then collected via Scopus to ascertain strengths of association with each source. Multiple linear regression analysis was used to identify significant contributors to high scholastic output. We identified 935 academic plastic surgeons with 94 (10.1%), 24 (2.6%), 724 (77.4%), and 62 (6.6%) receiving funding from PSF, AAPS, industry, and NIH, respectively. There were positive correlations in receiving NIH, PSF, and/or AAPS funding (P funding was found to negatively associate with PSF (r = -0.75, P = 0.022) grants. The NIH R award was consistently found to be the most predictive of academic output across bibliometrics, followed by the AAPS academic scholarship award. Conventional measures of academic seniority remained predictive across all measures used. Our study demonstrates for the first time interactions between industry, federal, and association funding. The NIH R award was the strongest determinant of high scholastic productivity. Recognition through AAPS academic scholarships seemed to associate with subsequent success in NIH funding.

    Full Text Available This paper examines the correlation between musical aptitude and pronunciation proficiency in an experiment with 29 university students of Spanish as a foreign language. The 29 participants took a test in Spanish pronunciation and prosody as well as in musicality. The pronunciation and prosody test consisted of two parts. The first part was a receptive phonemic discrimination test and the second part was a productive test in which they had to repeat words and sentences chosen for their prosodic characteristics. The musical aptitude test also consisted of a receptive part on musicality in general, as well as a productive part, which included the reproduction of tones, tone intervals, rhythms and the singing of a melody. The statistical analysis with Pearson’s correlation-coefficients revealed a positive correlation (although not for all aspects between the musical and foreign language pronunciation proficiency aptitudes.

Lo que sí hay son "criterios de exclusión" utilizados en profesiones de gran responsabilidad, en las cuales un error provocaría consecuencias graves para el trabajador o para terceros. Estos criterios son requisitos mínimos exigidos para la incorporación a un puesto de trabajo pero, están pensados desde un punto de vista de selección del personal más que de salud laboral. Objetivos: Conocer la situación actual en cuanto a la valoración de la aptitud para trabajar y comparar criterios de aptitud con criterios de exclusión para puestos de trabajo concretos. Metodología: La búsqueda de las referencias bibliográficas se realizó mediante palabras clave y descriptores DeCS. Se recuperaron 1593 citas. Tras aplicar los criterios de exclusión y realizar un análisis de pertinencia, se pudo conseguir a texto completo 23, encontrándose 7 artículos más relacionados con el tema en la búsqueda manual de la bibliografía. Resultados: Sólo dos artículos tratan el tema de la aptitud a fondo. Los cuadros de exclusión médica se ocupan de prácticamente todos los órganos y aparatos y de la aptitud psíquica, mientras que los artículos revisados tratan únicamente de algunos de estos aspectos. Conclusiones: La tendencia de la mayoría de los autores es prescindir del examen médico pre-empleo siempre que no sea obligatorio, y mantener los exámenes de salud periódicos.

In 2009 and 2010 it was used in the dental student selection process. The sample size in the regression models varies between 32 and 55 students. Results: Used as a supplement to the German GPA, the HAM-Nat test explained up to 12% of the variance in preclinical examination performance. We confirmed the prognostic validity of GPA reported in earlier studies in some, but not all of the individual preclinical examination results. Conclusion: The HAM-Nat test is a reliable selection tool for dental students. Use of the HAM-Nat yielded a significant improvement in prediction of preclinical academic success in dentistry.[german] Einleitung: In der vorliegenden Untersuchung wird der Frage nachgegangen, ob die Auswahl der Studierenden in der Zahnmedizin alleine durch die Abiturdurchschnittsnote erfolgen sollte oder ob sie durch den Einsatz eines fachspezifischen Studierfähigkeitstest verbessert werden kann.

    We examined 10-12-year old elementary school children's ability to preattentively process sound durations in music and speech stimuli. In total, 40 children had either advanced foreign language production skills and higher musical aptitude or less advanced results in both musicality and linguistic tests. Event-related potential (ERP) recordings of the mismatch negativity (MMN) show that the duration changes in musical sounds are more prominently and accurately processed than changes in speech sounds. Moreover, children with advanced pronunciation and musicality skills displayed enhanced MMNs to duration changes in both speech and musical sounds. Thus, our study provides further evidence for the claim that musical aptitude and linguistic skills are interconnected and the musical features of the stimuli could have a preponderant role in preattentive duration processing.

    After intensive, long-term musical training, the auditory system of a musician is specifically tuned to perceive musical sounds. We wished to find out whether a musician's auditory system also develops increased sensitivity to any sound of everyday life, experiencing them as noise. For this purpose, an online survey, including questionnaires on noise sensitivity, musical background, and listening tests for assessing musical aptitude, was administered to 197 participants in Finland and Italy. Subjective noise sensitivity (assessed with the Weinstein's Noise Sensitivity Scale) was analyzed for associations with musicianship, musical aptitude, weekly time spent listening to music, and the importance of music in each person's life (or music importance). Subjects were divided into three groups according to their musical expertise: Nonmusicians (N = 103), amateur musicians (N = 44), and professional musicians (N = 50). The results showed that noise sensitivity did not depend on musical expertise or performance on musicality tests or the amount of active (attentive) listening to music. In contrast, it was associated with daily passive listening to music, so that individuals with higher noise sensitivity spent less time in passive (background) listening to music than those with lower sensitivity to noise. Furthermore, noise-sensitive respondents rated music as less important in their life than did individuals with lower sensitivity to noise. The results demonstrate that the special sensitivity of the auditory system derived from musical training does not lead to increased irritability from unwanted sounds. However, the disposition to tolerate contingent musical backgrounds in everyday life depends on the individual's noise sensitivity.

    Research findings suggest that most students who have foreign language learning problems have language-based difficulties and, in particular, phonological processing problems. Authors of the present study examined pre- and posttest scores on native language and foreign language aptitude tests of three groups of at-risk high school students enrolled in special, self-contained sections of first-year Spanish. Two groups were instructed using a multisensory structured language (MSL) approach. One of the groups was taught in both English and Spanish (MSL/ES), the other only in Spanish (MSL/S). The third group (NO-MSL) was instructed using more traditional second language teaching methodologies. Significant gains were made by the MSL-ES group on measures of native language phonology, vocabulary, and verbal memory and on a test of foreign language aptitude; the MSL/S group made significant gains on the test of foreign language aptitude. No significant gains on the native language or foreign language aptitude measures were made by the NO-MSL group. Implications for foreign language classroom instruction of at-risk students are discussed.

    This study evaluated virtual reality (VR) simulation for endovascular training of medical students to determine whether innate perceptual, visuospatial, and psychomotor aptitude (VSA) can predict initial and plateau phase of technical endovascular skills acquisition. Twenty medical students received didactic and endovascular training on a commercially available VR simulator. Each student treated a series of 10 identical noncomplex renal artery stenoses endovascularly. The simulator recorded performance data instantly and objectively. An experienced interventionalist rated the performance at the initial and final sessions using generic (out of 40) and procedure-specific (out of 30) rating scales. VSA were tested with fine motor dexterity (FMD, Perdue Pegboard), psychomotor ability (minimally invasive virtual reality surgical trainer [MIST-VR]), image recall (Rey-Osterrieth), and organizational aptitude (map-planning). VSA performance scores were correlated with the assessment parameters of endovascular skills at commencement and completion of training. Medical students exhibited statistically significant learning curves from the initial to the plateau performance for contrast usage (medians, 28 vs 17 mL, P dexterity as well as with image recall at end of the training period. In addition to current recruitment strategies, VSA may be a useful tool for predictive validity studies.

    The number of students entering post-secondary education with already diagnosed disabilities is on the rise and mirrors the percentage of children in primary and secondary public schools with registered disabilities. Requirements governed by civil rights laws fundamentally change when comparing the support schools have to provide to students during primary and secondary school with disability access in postsecondary higher education. Psychiatrists may be asked to assist with scholastic disability at any stage of education and need to know about available supports and the parameters of disability in schools. Specifically, special attention should to be made in preparation for transition to postsecondary education when prior accommodations exist.

    The main focus of this study was to examine the relationship between musical aptitude and second language pronunciation skills. We investigated whether children with superior performance in foreign language production represent musical sound features more readily in the preattentive level of neural processing compared with children with less-advanced production skills. Sound processing accuracy was examined in elementary school children by means of event-related potential (ERP) recordings and behavioral measures. Children with good linguistic skills had better musical skills as measured by the Seashore musicality test than children with less accurate linguistic skills. The ERP data accompany the results of the behavioral tests: children with good linguistic skills showed more pronounced sound-change evoked activation with the music stimuli than children with less accurate linguistic skills. Taken together, the results imply that musical and linguistic skills could partly be based on shared neural mechanisms.

    To search the reach of educative strategy promoting the participation, to estimate the development of clinical aptitude and critical reading attaching the appropriate use of clinic research in cardiology residents. Prospective study. The instrument of clinical aptitude was constructed with five cases and 170 items and the instrument of critical reading was developed with five summaries of articles of clinical research in cardiology by 120 items. The strategy was performed with activities one a week during six months by two hours per class, in the period: March and September, 2005. Reading guides were delivered to the participants a week before that included a clinical case and clinic research of cardiology. During the activities in class we were promoting the participation and discussion. Both measuring instruments were performed in the first (initial measuring) and final session (final measuring). Non parametric test were used because the variable of the subjects were not normal distribution and the scale was ordinal. The reliability coefficient in both instruments with the Kuder-Richardson was 0.90 and 0.85 respectively. After educative strategy was observed a significant advance in the global calcifications, such as in critical reading and in clinical aptitude (p = 0.001 and 0.5 respectively). Analyzing in an independent manner the components of critical reading we found significant advancement in the indicators interpretation and judgment. In clinical aptitude we found significant progress in the indicators: the suitable use of paraclinics resources, the appropriate use of therapeutics measurement and iatropatogenic decisions for omission. The educative strategy promoting the participation, permitted to get a change in the clinical aptitude and critical reading attaching the appropriate use of sources of investigation in cardiology residents.

    To evaluate the aptitude of parents regarding the educational impact of equity education for children to prevent child sexual abuse using participatory strategies. Quasi-experimental design. Ninety-two parents with children in preschool were included in the study. The parents were given a course using participatory educational strategies for one hour daily over a period of 20 days. Prior to the course, a group of experts in child education and sexology prepared a questionnaire with 20 sentences. A Wilcoxon test was used to compare intergroup differences We found statistically significant differences in the parents' responses before and after the educational intervention, with a median (range) of 10(2-12)/18(6-20), pchild sexual abuse. Thus, it is imperative to continue evaluating different educational strategies.

    We developed a Self-Regulation Measure for Computer-based learning (SRMC) tailored toward medical students, by modifying Zimmerman's Self-Regulated Learning Interview Schedule (SRLIS) for K-12 learners. The SRMC's reliability and validity were examined in 2 studies. In Study 1, 109 first-year medical students were asked to complete the SRMC. Bivariate correlation analysis results indicated that the SRMC scores had a moderate degree of correlation with student achievement in a teacher-developed test. In Study 2, 58 third-year clerkship students completed the SRMC. Regression analysis results indicated that the frequency of medical students' usage of self-regulation strategies was associated with their general clinical knowledge measured by a nationally standardized licensing exam. These two studies provided evidence for the reliability and concurrent validity of the SRMC to assess medical students' self-regulation as aptitude. Future work should provide evidence to guide and improve instructional design as well as inform educational policy.

    Full Text Available After intensive, long-term musical training, the auditory system of a musician is specifically tuned to perceive musical sounds. We wished to find out whether a musician′s auditory system also develops increased sensitivity to any sound of everyday life, experiencing them as noise. For this purpose, an online survey, including questionnaires on noise sensitivity, musical background, and listening tests for assessing musical aptitude, was administered to 197 participants in Finland and Italy. Subjective noise sensitivity (assessed with the Weinstein′s Noise Sensitivity Scale was analyzed for associations with musicianship, musical aptitude, weekly time spent listening to music, and the importance of music in each person′s life (or music importance. Subjects were divided into three groups according to their musical expertise: Nonmusicians (N = 103, amateur musicians (N = 44, and professional musicians (N = 50. The results showed that noise sensitivity did not depend on musical expertise or performance on musicality tests or the amount of active (attentive listening to music. In contrast, it was associated with daily passive listening to music, so that individuals with higher noise sensitivity spent less time in passive (background listening to music than those with lower sensitivity to noise. Furthermore, noise-sensitive respondents rated music as less important in their life than did individuals with lower sensitivity to noise. The results demonstrate that the special sensitivity of the auditory system derived from musical training does not lead to increased irritability from unwanted sounds. However, the disposition to tolerate contingent musical backgrounds in everyday life depends on the individual′s noise sensitivity.

    While the Music Therapy Career Aptitude Test (MTCAT) provides a measure of student aptitude, measures of perceived self-efficacy may provide additional information about a students' suitability for a music therapy career. As a first step in determining whether future studies examining combined scores from the MTCAT and the Generalized Self-Efficacy (GSE) scale would be useful to help predict academic success in music therapy, we explored the internal reliability of these two measures in a sample of undergraduate students, and the relationship (concurrent validity) of the measures to one another. Eighty undergraduate music therapy students (14 male; 66 female) completed the MTCAT and GSE. To determine internal reliability we conducted tests of normality and calculated Cronbach's Coefficient Alpha for each measure. Pearson correlation coefficients were calculated to ascertain the strength of the relationship between the MTCAT and GSE. MTCAT scores were normally distributed and had high internal consistency (Cronbach's α = 0.706). GSE scores were not normally distributed, but had high internal consistency (Cronbach's α = 0.748). The correlation coefficient analysis revealed that MTCAT and GSE scores were moderately correlated ((r = 0.426, p music therapy students; however, a more complete picture of student suitability for music therapy may be determined by administering the GSE alongside the MTCAT. Future studies are needed to determine whether combined MTCAT and GSE scores can be used to predict student success in an undergraduate music therapy program. © the American Music Therapy Association 2014.

    The medical certificate of no contraindication to the practice of sport, requires prudence during the exam preceding its writing for medicals and medico-legal reasons. It needs a careful questioning on important points relative to the risk of health problems during a sportive effort, especially to seek for the prodoms which can be found in 7 to 50% of cases. This questioning can sometimes be specific to certain specialities of sport. Actually, even if the concept of mass screening identify for sports people, amateurs or not, is still much debated, we can consider as a reasonable attitude, in consulting with the general medicine, to practice a careful cardiovascular examination and an ECG whose the interpretation, done with the expertise required, could help to detect about 60% of the possible lethal abnormalities to the physical effort. In case of doubt during the exam, the complementary investigations are needed in some cases (echocardiogram, stress testing, myocardial perfusion, electrophysiological endocavitary exploration). After that, the used advices can be given to the sportive candidate to minimize the risks. Despite these precautions, a subit death because of the effort can non totally be avoided. Finally, it must be remembered that the behaviour to have for kid and for elderly person involves certain specificities to know.

    Full Text Available As university educators, we need to prepare students for the transition from the information age to what Daniel H. Pink (2005 calls the conceptual age, which is governed by artistry, empathy and emotion, by including in the curricula activities that stimulate both hemispheres of the brain. This can be done by promoting activities that energize what Daniel Goleman (1995 refers to as emotional intelligence, and it further maintains that, as Paul Ekman (2003 suggests, the ability to detect feelings improves communication. Recognizing the need to include in the curricula procedures that help develop students’ right brain aptitudes and enhance their communication skills, I have endeavoured to introduce dramatic scene study as a sustained activity in my English for Specific Purposes courses at the Universidad de Valencia. My aim was to energize the students’ creative and emotional aptitudes, as well as to dynamize effective teamwork. This article sustains that dramatic role-play, based on scripted scene study and related improvisational activities, is one way of achieving this.

  12. Relationships among musical aptitude, digit ratio and testosterone in men and women.

    Full Text Available Circulating adult testosterone levels, digit ratio (length of the second finger relative to the fourth finger, and directional asymmetry in digit ratio are considered sexually dimorphic traits in humans. These have been related to spatial abilities in men and women, and because similar brain structures appear to be involved in both spatial and musical abilities, neuroendocrine function may be related to musical as well as spatial cognition. To evaluate relationships among testosterone and musical ability in men and women, saliva samples were collected, testosterone concentrations assessed, and digit ratios calculated using standardized protocols in a sample of university students (N = 61, including both music and non-music majors. Results of Spearman correlations suggest that digit ratio and testosterone levels are statistically related to musical aptitude and performance only within the female sample: A those females with greater self-reported history of exposure to music (p = 0.016 and instrument proficiency (p = 0.040 scored higher on the Advanced Measures of Music Audiation test, B those females with higher left hand digit ratio (and perhaps lower fetal testosterone levels were more highly ranked (p = 0.007 in the orchestra, C female music students exhibited a trend (p = 0.082 towards higher testosterone levels compared to female non-music students, and D female music students with higher rank in the orchestra/band had higher testosterone levels (p = 0.003 than lower ranked students. None of these relationships were significant in the male sample, although a lack of statistical power may be one cause. The effects of testosterone are likely a small part of a poorly understood system of biological and environmental stimuli that contribute to musical aptitude. Hormones may play some role in modulating the phenotype of musical ability, and this may be the case for females more so than males.

Our analysis examines the correlation between successful homework completion rates and exam performance as well as how changes in homework completion correlate with changes in exam scores for students with different physics aptitudes. On average, successfully completing many homework problems correlated to better exam scores only for students with high physics aptitude. On the other hand, all other students showed zero or even a negative correlation between successful homework completion and exam performance. Low- and medium-aptitude students who did more homework did no better and sometimes scored lower on exams than their low- and medium-aptitude peers who did less homework. Our work also shows that long-term changes in homework completion correlated to long-term changes in exam scores only for students with high physics aptitude, but not for students with medium or low aptitude. We offer several explanations for the disparity in homework learning gains, including cognitive load theory, ineffective homework strategies, and various mismatches between homework and exams. Several solutions are proposed to address these possible deficiencies in graded online and written homework.

    The origin of individual differences in aptitude, defined as a domain-specific skill within the normal ability range, and talent, defined as a domain specific skill of exceptional quality, is under debate. The nature of the variation in aptitudes and exceptional talents across different domains was investigated in a population based twin sample. Self-report data from 1,685 twin pairs (12-24 years) were analyzed for Music, Arts, Writing, Language, Chess, Mathematics, Sports, Memory, and Knowledge. The influence of shared environment was small for both aptitude and talent. Additive and non-additive genetic effects explained the major part of the substantial familial clustering in the aptitude measures with heritability estimates ranging between .32 and .71. Heritability estimates for talents were higher and ranged between .50 and .92. In general, the genetic architecture for aptitude and talent was similar in men and women. Genetic factors contribute to a large extent to variation in aptitude and talent across different domains of intellectual, creative, and sports abilities.

  19. Measuring Scholastic Production by Dermatopathologists Using the H-Index: A Cross-Sectional Study.

    2018-06-01

    Academic advancement in dermatopathology requires evidence of scientific production. The H-index is a useful bibliometric for measuring scientific production because it weights both volume and impact of an individual's scholastic production. The H-index distribution among academic dermatopathologists is unknown. In this cross-sectional study of 299 dermatopathologists with academic appointments in North America, H-index, publication counts, and citation counts were retrieved from Thomas Reuters Web of Science. Analytic statistics were performed to identify best predictors of academic rank and cutoff points between academic ranks. The H-index was a superior predictor of overall academic rank than publication or citation counts. The median H-index for assistant, associate, and full professors was 4, 6, and 11, respectively. H-index cutoff scores of 8 and 10 favored associate and full professor rank, respectively. These data provide benchmarks for dermatopathologists to gauge their scientific productivity against that of their peers. Although advancement decisions will depend on a careful examination of the scope and impact of a candidate's work, assistant professors of dermatopathology with H-index scores of >7 and associate professors of dermatopathology with H-index scores of >9 may wish to consider application for promotion.

    Full Text Available The text proposes the examination of school and educational policy choices made in the territories of Trentino and Alto Adige, for German and Ladin speaking minorities in the time period between the end of the first major world conflict and the beginning of the second. During the historical period under consideration, the territories of the new provinces were headquarters and object of multiple political, economic and cultural operations, marked by different and opposite strategies: referrals of implicit nationalist trend which attributed extensive legislative powers to central authorities, were replaced by more democratic guidelines, that embraced local autonomies and recognized the rights of the minorities. Search for a political balance between the two instances, which was initially pursued, left the field with the arrival of the first fascist government to a new scenario with the aim of Italianize, even with the use of violence, the kind and organization of the new provinces. The same contradictory scenario will mark the evolution of educational policies in the new territories; the attempt to extend the Italian scholastic regulations to new provinces, first gradually and respectfully on the linguistic minorities, their schools and traditions, with the fascist government will suffer a significant change in behavior and reasoning. The theme of this research, which is little studied and analyzed in detail, assumes its relevance, whether in terms of historical and educational research linked to particular historic moment and geographical context, whether in terms of the consequences that it had in the construction of the Italian Republic.

    Substance abuse among adolescents is a major public health and social problem. However, studies rarely investigate the relationships between substance abuse, educational achievement and sport factors. Substance abuse is an even more significant problem in societies that have experienced trauma, such as Bosnia and Herzegovina, which have had recent wars. The aims of this study were to investigate substance abuse among adolescents in Bosnia and Herzegovina and to study the potential gender-specific relationships between a) sport factors (physical activity/exercise/athletic participation) and substance abuse and b) scholastic achievement and substance abuse. Our sample consisted of 1,032 adolescents who were 17 to 18 years old (435 boys and 597 girls) and who were in the final grade of high school. These subjects were randomly selected from the territory of Herzegovina-Neretva Canton of Bosnia and Herzegovina. Retrospective testing was performed using an extensive self-administered questionnaire. The questionnaire included questions involving topics such as sociodemographic variables, scholastic variables, sport factors, and substance abuse data (smoking habits, drugs consumption and alcohol consumption using the AUDIT questionnaire). Descriptive statistics, frequencies, analyses of the differences and correlational analyses were performed. Our results found that greater than one-third of the boys and one-fourth of the girls were daily smokers, and almost half of the boys and one-fifth of the girls practiced harmful drinking; other drugs (i.e. heroin, cocaine, amphetamines, etc.) were rarely consumed. Boys dominated in sport factors, whereas girls were more successful in scholastic achievement. Approximately 23% of the boys and 6% of the girls reported that they practiced harmful drinking and smoked simultaneously. Educational failure, which was defined as having one or more negative grades at the end of the last two school years, was identified in 20% of the boys

    According to research findings, most students who experience foreign language learning problems are thought to have overt or subtle native language learning difficulties, primarily with phonological processing. A recent study by the authors showed that when a multisensory structured language approach to teaching Spanish was used with a group of at-risk high school students, the group's pre- and posttest scores on native language phonological processing, verbal memory and vocabulary, and foreign language aptitude measures significantly improved. In this replication and follow-up study, the authors compared pre- and posttest scores of a second group of students (Cohort 2) who received MSL instruction in Spanish on native language and foreign language aptitude measures. They also followed students from the first study (Cohort 1) over a second year of foreign language instruction. Findings showed that the second cohort made significant gains on three native language phonological measures and a test of foreign language aptitude. Follow-up testing on the first cohort showed that the group maintained its initial gains on all native language and foreign language aptitude measures. Implications for the authors' Linguistic Coding Deficit Hypothesis are discussed and linked with current reading research, in particular the concepts of the assumption of specificity and modularity.

    Full Text Available Two strains (B7 and Z8 of the Leuconostoc mesenteroides subspecies mesenteroides that were isolated from Algerian camel milk from an initial pool of 13 strains and demonstrated a high ability to inhibit the growth of Listeria spp. were selected and characterised at the phenotypic and genotypic levels. Probiotic profiling and inhibition spectra against food borne pathogens in mixed cultures were also investigated. The bacteriocin produced by L. mesenteroides strain B7 was identified as leucocin B by specific PCR. In vitro studies demonstrated that both Leuconostoc mesenteroides strains exhibited a marked probiotic profile, showing high survival at low pH (2-3 and 4 in the presence of 0.5%, 1%, and 2% of bile salts and at pH 3 in the presence of 3 mg/mL pepsin. Susceptibility testing against antimicrobial agents was also performed for both strains. When tested in a mixed culture with Listeria innocua, Listeria ivanovii, or Staphylococcus aureus, strain B7 reduced the numbers of these species by 1.87, 1.78, and 1.38 log units, respectively. Consequently, these two strains were found to possess good probiotic properties in vitro and a high capacity for Listeria spp. inhibition in mixed cultures. Therefore, these strains have a favourable technological aptitude and a potential application as novel probiotic starters.

    Full Text Available Intelligent Tutoring Systems (ITS is an act of impacting knowledge while computer teaches or acts as the tutors which is a supplement to human teachers. The ability to teach each student based on their individual abilities a major advantage posed by ITS and that is why it is being embraced in this work. This work describes the design of an Intelligent Tutoring System that was tagged Scholastic tutor (St*, which has the individual learning and collaborative problem-solving modules. The individual tutoring module was designed to provide appropriate lessons to individuals based on his/her background knowledge level, interest, and learning style and assimilation rate prior to using the tutoring system. A software agent is used to monitor and process these parameters, arrange the learning topic, and exercises, for each individual. The collaborative problem-based tutoring module was designed to present tutorial problems and provides facilities to assist learners with some useful information and advice for problem solving. This is because the present lecturing methodology which is the conventional teaching methodology provides an interactive classroom setting that promotes the open exchange of ideas and allows for the lecturer to communicate directly with the students but has a great disadvantage of not teaching all the students according to their own learning rate and pace. The intelligent tutor solves this problem by providing individualised learning for each student where they can learn according to their own pace and learning abilities it will provide remedy and advice when learners encounter difficulties during learning session. The classical model of ITS architecture has four main modules; domain model, student model, tutoring model and the user interface model.

    Since the application of technical medicine by the Greeks, modern neurology has been based on a body of knowledge and cultural heritage from ancient times. In this paper we review the contribution made by Al Andalus to neuroscience during the Middle Ages and its repercussions on modern neurology. Following the death of Mohammed in the vii century AD, Islam enjoyed one of the most spectacular periods of expansion in the history of mankind. Occupation of the cities of Alexandria and Gundishapur put the Arabs into contact with original Greco Latin manuscripts, which were assimilated and divulged by Islamic scientists in the middle eastern caliphates of Damascus and Bagdad as well as the western caliphates of Al Andalus (Spain) and Kairwan (Tunis). This classical hippocratico galenico medicine was refashioned into the so called arabized galenism, which markedly influenced the Scholastics and the cultured world of the lower Middle Ages and became the basis of European medicine until well into the Renaissance period. There was a first Spanish cultural Renaissance in Al Andalus during the ix xii centuries, which led to a flowering unheard of in the Middle Ages before then. Andalusian doctors made major contributions to the body of knowledge about neuroscience and developed major philosophical concepts of human understanding. Thus, Abulcasis (936 1013), the father of modern surgery, developed material and technical designs which are still used in neurosurgery. Averroes suggested the existence of Parkinson s syndrome and attributed photoreceptor properties to the retina. Avenzoar described meningitis, intracranial thrombophlebitis, mediastinal tumours and made contributions to modern neuropharmacology. Maimonides wrote about neuropsychiatric disorders and described rabies and belladonna intoxication. Aside from the political, religious and cultural differences between Al Andalus and the Christian kingdoms of the Iberian peninsula, the historical Andalusian period (711 1492

The aim was to determine the level of word processing at which grammatical information shows its differential effects in groups of subjects who themselves differ in verbal ability. For this purpose, the psycholinguistic tasks applied were grammatically primed reading aloud and grammatically primed grammatical classification with an appropriate control of extra-linguistic factors that may have affected aforementioned tasks. Verbal aptitude was assessed in a psychometric manner, and the subjects were divided into "high verbal" and "low verbal" groups. Taking into account statistical control of extra-linguistic factors, the results indicate that groups of high verbal and low verbal subjects cannot be differentiated based on reading aloud performance. The high verbal subjects, however, were more efficient in grammatical classification than low verbal subjects. The results also indicated that the presence of grammatical information embedded in function words-primes had a stronger effect on word processing in low verbal group. Such pattern of results testify to the advantage of high verbal subjects in lexical and post lexical processing, while no differences were established in the word recognition processes. The implications of these findings were considered in terms of test construction for the assessment of verbal ability in Serbian language. .

  10. I. An introduction to the relation of physical activity to cognitive and brain health, and scholastic achievement.

    The current pandemic of physical inactivity threatens both physical and cognitive health throughout the lifespan. This monograph describes the multidisciplinary study of aspects of childhood health and its relationship to cognitive and brain function, and scholastic performance. Specifically, we focus on physical activity and physical fitness along with nutrition and obesity; interconnected aspects of health that have declined over the past 30 years in children of industrialized nations. Although much emphasis has been placed on correcting physical aspects of these public health concerns, it is only more recently that attention has been paid to the relation between physical health and cognitive health among school age children. The monograph begins with an overview of current behavioral trends that compete with physical activity engagement and contribute to the failure to achieve the public health recommendations for physical activity among children in the United States. Following the epidemiological overview, the relation of childhood fitness to brain structure and function is examined among children with varying fitness levels. The observed dissimilarities between higher- and lower-fit children are discussed within the context of typical brain development. To broaden the scope of research presented herein, the relation of nutrient intake--among both undernourished and well-nourished children--and obesity on cognition and brain are discussed. Next, novel empirical data are presented from a correlational study that indicates a differential relation between childhood fitness and adiposity on various aspects of cognition. In an effort to provide a more comprehensive review, a later chapter is dedicated to describing a small body of literature investigating the relation of physical activity to special populations of children, including those with learning disorders. In doing so, practical applications as well as challenges and limitations of implementing physical

    The aim of this study was to investigate the relationship between sleep duration, wake time, and hours studying on high school grades and performance on the Scholastic Aptitude Test (SAT)/ American College Testing (ACT) college entrance exams. Data were collected from 13,071 recently graduated high school seniors who were entering college in the fall of 2014. A column proportions z test with a Bonferroni adjustment was used to analyze proportional differences. Analysis of covariance (ANCOVA) was used to examine mean group differences. Students who woke up prior to 6 a.m. and got less than 8 h of sleep (27 %) were significantly more likely to report studying 11 or more hours per week (30 %), almost double the rate compared to students who got more than 8 h of sleep and woke up the latest (16 %). Post hoc results revealed students who woke up at 7 a.m. or later reported significantly higher high school grades than all other groups (p students who woke up between 6:01 a.m. and 7:00 a.m. and got eight or more hours of sleep. The highest reported SAT/ACT scores were from the group that woke up after 7 a.m. but got less than 8 h sleep (M = 1099.5). Their scores were significantly higher than all other groups. This study provides additional evidence that increased sleep and later wake time are associated with increased high school grades. However, this study also found that students who sleep the longest also reported less studying and lower SAT/ACT scores.

    Research points to the positive impact that gender-segregated schooling and classroom initiatives exert on academic attainment. An evaluation of these studies which reveal positive effects highlights, however, that students are typically selectively assigned to single- or mixed-gender instructional settings, presenting a methodological confound. The current study controls for students' prior attainment to appraise the efficacy of a single-gender classroom initiative implemented in a co-educational high school in the United Kingdom. Secondary data analysis (using archived data) was performed on 266 middle-ability, 11-12 year-old students' standardized test scores in Languages (English, foreign language), STEM-related (Mathematics, Science, Information and Communication Technology), and Non-STEM subjects (art, music, drama). Ninety-eight students (54, 55% female) were taught in single-gender and 168 (69, 41% female) in mixed-gender classrooms. Students undertook identical tests irrespective of classroom type, which were graded in accordance with U.K national curriculum guidelines. Controlling for students' prior attainment, findings indicate that students do not appear to benefit from being taught in single-gender relative to mixed-gender classrooms in Language and STEM-related subjects. Young women benefitted from being taught in mixed-gender relative to single-gender classes for Non-STEM subjects. However, when prior ability is not controlled for, the intervention appears to be effective for all school subjects, highlighting the confounding influence of selective admissions. These findings suggest that gender-segregated classroom initiatives may not bolster students' grades. It is argued that studies that do not control for selection effects may tell us little about the effectiveness of such interventions on scholastic achievement.

    Introduction: Works evaluation and critique is one of the most important phases in scientific production cycle. Reviewers need some aptitude about rules and principles of writing good review. Considering the important role of books for storage and transferring the scientific findings, book reviewing is vital to scientific progress. Despite this fact, investigation of Isfahan University of Medical Science's journal, demonstrated the number of published book reviews to be very small. This study aims to investigate the influence of reviewing training courses on participants’ book reviewing awareness, attitude, and aptitude. Materials and Methods: The study method is experimental with two group design (with pre-test and post-test) and applied. Statistical population is of all faculty members of the faculty of management and medical information of Isfahan University of Medical Science, including both hired and contracted employees, which, according to faculty's department of Education, consists of 86 people. The sampling method used in this study is random. Number of samples in case and control groups was calculated using the following equation of n= (z1 + z2) 2 (2s2)/d2 and is 15 people. One checklist and two questionnaires were the means of data collection. Data were analyzed using SPSS 18.0 software and two level of descriptive (mean and SD) and inferential statistics (t-test and t-paired). Results: Findings showed that the mean score of awareness of book reviews in case group increased meaningfully after the training course (55.7) compared to the score prior to the intervention (33.1), P book reviews in control group remained mostly the same before (31.6) and after intervention (35.1), P = 0.35.

    Adolescence is considered to be the most important period for the prevention of substance use and misuse (SUM). The aim of this study was to investigate the problem of SUM and to establish potentially important factors associated with SUM in Kosovar adolescents. Multi-stage simple random sampling was used to select participants. At the end of their high school education, 980 adolescents (623 females) ages 17 to 19 years old were enrolled in the study. The prevalence of smoking, alcohol consumption (measured by Alcohol Use Disorder Identification Test-AUDIT), and illegal drug use (dependent variables), as well as socio-demographic, scholastic, familial, and sports-related factors (independent variables), were assessed. Boys smoke cigarettes more often than girls with daily-smoking prevalence of 16% among boys and 9% among girls (OR = 1.85, 95% = CI 1.25-2.75). The prevalence of harmful drinking (i.e., AUDIT scores of >10) is found to be alarming (41% and 37% for boys and girls, respectively; OR = 1.13, 95% CI = 0.87-1.48), while 17% of boys and 9% of girls used illegal drugs (OR = 2.01, 95% CI = 1.35-2.95). The behavioral grade (observed as: excellent-average-poor) is the factor that was most significantly correlated with SUM both in boys and girls, with lower behavioral grades among those adolescents who consume substances. In girls, lower maternal education levels were associated with a decreased likelihood of SUM, whereas sports achievement was negatively associated with risky drinking. In boys, sports achievement decreased the likelihood of daily smoking. Information on the factors associated with SUM should be disseminated among sports and school authorities.

    The objective of this study was to evaluate the effect of physical activity from the "Menopause in Form" program on physical aptitude, functional capacity, corporal balance and QoL among elderly women. In addition, correlations among these variables were examined. The present work was a longitudinal study that was quasi-experimental and correlational. A total of 323 elderly women (age: 69.0±5.53 years) participated in this study. Subjects were non-institutionalized, post-menopausal individuals residing at the Elderly Care Center in Belém Municipality (Pará, Brazil) and practiced one activity (i.e., dancing or walking) over a 10-month period. The assessment protocols used were the following: the Fullerton functional fitness test battery (physical aptitude); the activities of daily living (ADL) indices (functional capacity); the Tinetti-scale (corporal balance); and the WHOQOL-OLD questionnaire (QoL). The adopted significance level was p<0.05. Results from the Wilcoxon test demonstrated significant differences for the post-test assessment of functional capacity (Δ%=5.63%; p=0.0001) and general QoL (Δ%=9.19%; p=0.001). These results suggest that the physical activities employed during the "Menopause in Form" program resulted in significant improvements in the functional capacity and QoL of post-menopausal elderly women.

    Lauer, Jillian E; Lourenco, Stella F

    2016-10-01

    Despite considerable interest in the role of spatial intelligence in science, technology, engineering, and mathematics (STEM) achievement, little is known about the ontogenetic origins of individual differences in spatial aptitude or their relation to later accomplishments in STEM disciplines. The current study provides evidence that spatial processes present in infancy predict interindividual variation in both spatial and mathematical competence later in development. Using a longitudinal design, we found that children's performance on a brief visuospatial change-detection task administered between 6 and 13 months of age was related to their spatial aptitude (i.e., mental-transformation skill) and mastery of symbolic-math concepts at 4 years of age, even when we controlled for general cognitive abilities and spatial memory. These results suggest that nascent spatial processes present in the first year of life not only act as precursors to later spatial intelligence but also predict math achievement during childhood.

    Full Text Available Breeding of forage maize should combine improvement achieved for grain with the specific needs of forage hybrids. Production stability is important when maize is used for silage if the planting area is not in the ideal agronomic environment. The objectives of the present research were: (i to quantify environmental and genetic and their interaction effects on maize silage traits; (ii to identify possible heterotic groups for forage aptitude and suggest the formation of potential heterotic patterns, and (iii to identify suitable inbred line combinations for producing hybrids with forage aptitude. Forty-five hybrids derived from diallelic crosses (without reciprocals among ten inbred lines of maize were evaluated in this study. Combined ANOVA over environments showed differences between genotypes (G, environments (E, and their interactions (GEI. Heritability (H2, and genotypic and phenotypic correlations were estimated to evaluate the variation in and relationships between forage traits. Postdictive and predictive AMMI models were fitted to determine the importance of each source of variation, G, E, and GEI, and to select genotypes simultaneously on yield, quality and stability. A predominance of additive effects was found in the evaluated traits. The heterotic pattern Reid-BSSS × Argentine flint was confirmed for ear yield (EY and harvest index (HI. High and broad genetic variation was found for stover and whole plant traits. Some inbred lines had genes with differential breeding aptitude for ear and stover. Stover and ear yield should be the main breeding objectives in maize forage breeding.

    Combined heredity of surnames and physique, coupled with past marriage patterns and trade-specific physical aptitude and selection factors, may have led to differential assortment of bodily characteristics among present-day men with specific trade-reflecting surnames (Tailor vs. Smith). Two studies reported here were partially consistent with this genetic-social hypothesis, first proposed by Bäumler (1980). Study 1 (N = 224) indicated significantly higher self-rated physical aptitude for prototypically strength-related activities (professions, sports, hobbies) in a random sample of Smiths. The counterpart effect (higher aptitude for dexterity-related activities among Tailors) was directionally correct, but not significant, and Tailor-Smith differences in basic physique variables were nil. Study 2 examined two large total-population-of-interest datasets (Austria/Germany combined, and UK: N = 7001 and 20532) of men’s national high-score lists for track-and-field events requiring different physiques. In both datasets, proportions of Smiths significantly increased from light-stature over medium-stature to heavy-stature sports categories. The predicted counterpart effect (decreasing prevalences of Tailors along these categories) was not supported. Related prior findings, the viability of possible alternative interpretations of the evidence (differential positive selection for trades and occupations, differential endogamy and assortative mating patterns, implicit egotism effects), and directions for further inquiry are discussed in conclusion.

    Simulation in medical education provides students with opportunities to practice interviews, examinations, and diagnosis formulation related to complex conditions without risks to patients. To examine differences between individual and team participation on learning outcomes and student perspectives through use of virtual patients (VPs) for teaching cranial nerve (CN) evaluation. Fifty-seven medical students were randomly assigned to complete simulation exercises either as individuals or as members of three-person teams. Students interviewed, examined, and diagnosed VPs with possible CN damage in the neurological exam rehearsal virtual environment (NERVE). Knowledge of CN abnormalities was assessed pre- and post-simulation. Student perspectives of system usability were evaluated post-simulation. An aptitude-treatment interaction (ATI) effect was detected; at pre-test scores ≤ 50%, students in teams scored higher (83%) at post-test than did students as individuals (62%, p = 0.02). Post-simulation, students in teams reported greater confidence in their ability to diagnose CN abnormalities than did students as individuals (p = 0.02; mean rating = 4.0/5.0 and 3.4/5.0, respectively). The ATI effect allows us to begin defining best practices for the integration of VP simulators into the medical curriculum. We are persuaded to implement future NERVE exercises with small teams of medical students.

  13. Hybridizing scholastic psychology with Chinese medicine: a seventeenth-century Chinese Catholic's conceptions of xin (mind and heart).

    Science.gov (United States)

    Zhang, Qiong

    2008-01-01

    This paper explores the dynamics of cultural interactions between early modern China and Europe initiated by the Jesuits and other Catholic missionaries through a case study of Wang Honghan, a seventeenth-century Chinese Catholic who systematically sought to integrate European learning introduced by the missionaries with pre-modern Chinese medicine. Focusing on the ways in which Wang combined his Western and Chinese sources to develop and articulate his views on xin (mind and heart), this paper argues that Wang arrived at a peculiar hybrid between scholastic psychology and Chinese medicine, not so much through a course of haphazard misunderstanding as through his conscious and patterned use and abuse of his Western sources, which was motivated most possibly by a wish to define a theoretical position that most suited his social roles as a Catholic convert and a Chinese medical doctor. Thus, rather than seeing Wang as an epitome of"transmission failure," this paper offers it as a showcase for the tremendous dynamism and creativity occurring at this East-West "contact zone as representatives of both cultures sought to appropriate and transform the symbolic and textual resources of the other side.

    We examined the effectiveness of a metacognitive intervention for written language performance, based on the Hayes model of written expression, for 73 fourth-grade (n = 38) and fifth-grade (n = 35) students. The intervention consisted of twenty 45-min writing lessons designed to improve their awareness of writing as a problem-solving process. Each of the lessons addressed some aspect of planning, translating, and reflecting on written products; their self-regulation of these processes; and actual writing practice. All instruction was conducted in intact classrooms. Prior to the intervention, all students received a battery of neurocognitive tests measuring executive functions, attention, and language. In addition, preintervention writing samples were obtained and analyzed holistically and for errors in syntax, semantics, and spelling. Following the intervention, the writing tasks were readministered and cluster analysis of the neurocognitive data was conducted. Cluster analytic procedures yielded 7 reliable clusters: 4 normal variants, 1 Problem Solving weakness, 1 Problem Solving Language weaknesses, and 1 Problem Solving strength. The response to the single treatment by these various subtypes revealed positive but modest findings. Significant group differences were noted for improvement in syntax errors and spelling, with only spelling showing differential improvement for the Problem Solving Language subtype. In addition, there was a marginally significant group effect for holistic ratings. These findings provide initial evidence that Writing Aptitude (subtype) x Single Treatment interactions exist in writing, but further research is needed with other classification schemes and interventions.

    Full Text Available Agricultural land evaluation in the fluvial-marine plain within the municipality of Tuxpan, Nayarit, was carried out based onto a semi-detailed soil survey. Relative agricultural aptitude was evaluated, through out a modified Almagra’s model of MicroLeis 4.1 system, defining a new model: the Almagra-Tuxpan, based on the specific conditions of the zone. Using the Almagra-Tuxpan model, a software routine was written to evaluate the agricultural aptitude of twelve traditional crops (bean, sorghum, maize, tobacco (Virginia and Burley, chili, tomato, melon, watermelon, jícama, peanut, and cotton, after that, the relative agricultural aptitude was determined for every one of the mapped soils units. 21.73 % of the soils have a very good aptitude for the majority of the evaluated farming, 59.98 % have a moderate aptitude, and the remaining 18.43 % have no capacity at all. Generally speaking, excluding the units with null capacity, the soils of this municipality are suitable for farming cotton, maize and sorghum. The last two, are already intensely cultivated, meanwhile cotton will be a very good alternative for the region.

    Music perception and practice represent complex cognitive functions of the human brain. Recently, evidence for the molecular genetic background of music related phenotypes has been obtained. In order to further elucidate the molecular background of musical phenotypes we analyzed genome wide copy number variations (CNVs) in five extended pedigrees and in 172 unrelated subjects characterized for musical aptitude and creative functions in music. Musical aptitude was defined by combination of the scores of three music tests (COMB scores): auditory structuring ability, Seashores test for pitch and for time. Data on creativity in music (herein composing, improvising and/or arranging music) was surveyed using a web-based questionnaire.Several CNVRs containing genes that affect neurodevelopment, learning and memory were detected. A deletion at 5q31.1 covering the protocadherin-α gene cluster (Pcdha 1-9) was found co-segregating with low music test scores (COMB) in both sample sets. Pcdha is involved in neural migration, differentiation and synaptogenesis. Creativity in music was found to co-segregate with a duplication covering glucose mutarotase gene (GALM) at 2p22. GALM has influence on serotonin release and membrane trafficking of the human serotonin transporter. Interestingly, genes related to serotonergic systems have been shown to associate not only with psychiatric disorders but also with creativity and music perception. Both, Pcdha and GALM, are related to the serotonergic systems influencing cognitive and motor functions, important for music perception and practice. Finally, a 1.3 Mb duplication was identified in a subject with low COMB scores in the region previously linked with absolute pitch (AP) at 8q24. No differences in the CNV burden was detected among the high/low music test scores or creative/non-creative groups. In summary, CNVs and genes found in this study are related to cognitive functions. Our result suggests new candidate genes for music perception

    Full Text Available Language learning belief and language learning strategies are two essential predictors that have significant effect toward students’ language proficiency. Learners’ belief is dealing with what comes from inside the learners in learning the language, such as foreign language aptitude; difficulty of language learning; nature of language learning; learning and communication strategies; and motivation. Meanwhile, language learning strategies are learners’ plan in achieving certain goals or mastering the target language. A preliminary research was conducted in order to find what strategy mostly used by the learners. It turned out that the strategy mostly used by them was metacognitive strategies. Thus, this study aims to investigate about the correlation between metacognitive strategies and certain belief’ variables in students’ language learning which are foreign language aptitude and motivation. Moreover, twenty postgraduate students of English education department participated in this study. This study used correlational research, in which the BALLI (Beliefs about Language Learning Inventory and SILL (Strategies Inventory for Language Learners questionnaires were adopted as the instruments in collecting the data. The findings of this study indicated that there is negative linear correlation between metacognitive strategy and foreign language aptitude (rXY = -0,049 while there is significant positive linear correlation between metacognitive and motivation (rXY =+0,79 in students’ language learning. Furthermore, this study also provide some recommendations, which is it is expected that there will be more researches use studies using different respondents with various contexts. Secondly, the further research will use both of quantitative and qualitative data relating to this issue in order to make a more accurate data.

  1. Subcortical processing of speech regularities underlies reading and music aptitude in children

    2011-01-01

    Background Neural sensitivity to acoustic regularities supports fundamental human behaviors such as hearing in noise and reading. Although the failure to encode acoustic regularities in ongoing speech has been associated with language and literacy deficits, how auditory expertise, such as the expertise that is associated with musical skill, relates to the brainstem processing of speech regularities is unknown. An association between musical skill and neural sensitivity to acoustic regularities would not be surprising given the importance of repetition and regularity in music. Here, we aimed to define relationships between the subcortical processing of speech regularities, music aptitude, and reading abilities in children with and without reading impairment. We hypothesized that, in combination with auditory cognitive abilities, neural sensitivity to regularities in ongoing speech provides a common biological mechanism underlying the development of music and reading abilities. Methods We assessed auditory working memory and attention, music aptitude, reading ability, and neural sensitivity to acoustic regularities in 42 school-aged children with a wide range of reading ability. Neural sensitivity to acoustic regularities was assessed by recording brainstem responses to the same speech sound presented in predictable and variable speech streams. Results Through correlation analyses and structural equation modeling, we reveal that music aptitude and literacy both relate to the extent of subcortical adaptation to regularities in ongoing speech as well as with auditory working memory and attention. Relationships between music and speech processing are specifically driven by performance on a musical rhythm task, underscoring the importance of rhythmic regularity for both language and music. Conclusions These data indicate common brain mechanisms underlying reading and music abilities that relate to how the nervous system responds to regularities in auditory input

  5. Explaining academic-track boys' underachievement in language grades: Not a lack of aptitude but students' motivational beliefs and parents' perceptions?

    Boys earn lower grades in languages than girls. The expectancy-value model by Eccles et al. (, A series of books in psychology. Achievement and achievement motives. Psychological and sociological approaches, W.H. Freeman, San Francisco, CA, 76) is a comprehensive theoretical model for explaining gender differences in educational outcomes. In the past, most studies have focused on girls' disadvantage in math and science and on the role of the students' motivational beliefs. We aimed to explain boys' lower language grades by applying the expectancy-value model while taking into account students' motivational beliefs as well as their aptitude, prior achievement, and socializers' beliefs. In addition, we aimed at exploring the incremental contribution of each potential mediator. Five hundred and twenty German students (age M = 17 years; 58% female) and 374 parents (age M = 47 years). Student-reported ability self-concept (ASC) and task values, parents' perceptions of students' ability, students' prior achievement as reported by schools, and students' verbal intelligence test scores were all tested as mediators of the effect of gender on grades in German while controlling for parents' socioeconomic status. Single-mediator models and a multiple-mediator model were estimated using structural equation modelling. All variables proved to be relevant for explaining boys' underachievement in language grades. Whereas students' ASC, task values, prior achievement, and parents' perceptions mediated the gender effect, verbal intelligence was identified as a suppressor variable increasing the gender effect. Our results challenge the stereotypic belief that boys' lower grades are due to lower verbal aptitude. Rather, students' motivational beliefs and parents' perceptions seem critical factors. Implications for both future research and practice are discussed. © 2017 The British Psychological Society.

    Adolescence is a period characterized by rapid physical, emotional, and mental growth and changes potentially resulting in health challenges. Anemia, which is a fairly common complication in this age group, is reported to negatively affect the cognitive ability of adolescents. Traditionally, ragi (Finger millet: Eleusine coracana), a cereal available in India, has been recommended as nutritional supplement to combat anemia because of its high protein and mineral content as well as anti-microbial property. This study sought to establish the effect of ragi in improving hematological parameters, body mass index, and scholastic performance among adolescent school girls. Sixty adolescent girls were randomly selected and divided into intervention (n = 30) and control groups (n = 30). The effect of dietary supplementation of ragi porridge on hematological parameters was evaluated on the intervention group at 45 and 90 days. Both groups were monitored for changes in body mass index and scholastic performance. A statistically significant increase in hemoglobin levels was observed in the intervention group after 90 days (from a mean of 11.3 g% to 12.54 g%; t (29)  = 7.514, p < .0001), with no significant changes in the control group. No statistically significant differences between the two groups were observed for mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, mean corpuscular volume, red cell distribution width, body mass index, and scholastic performance. The data show that daily dietary supplementation with ragi porridge has a positive effect on hemoglobin levels in adolescent high schools girls. A well planned nutrition education with dietary supplementation is thus recommended for better outcomes.

  7. [Education in our time: competency or aptitude? The case for medicine. Part I].

    Science.gov (United States)

    Viniegra-Velázquez, Leonardo

    This paper begins with a statement: It is necessary to characterize the respective society to be able to understand the education's core. Distinctive features of the present-day world lead us to define it as the ruin of a civilization based on limitless financial gain, where education has a passive quality, responsible of maintaining the status quo as well as preserving the degrading attributes of actual societies: individualism, passivity, competitiveness, consumerism and high vulnerability to control and manipulation. About the dilemma: competency or aptitude, these are not synonyms but concepts pertaining radically different approaches to the practice and understanding of education. Competency represents the actual tendencies of passive education, where knowledge is just about acquiring information. Aptitude refers to participatory education, described in the second part of this essay. The passive education is present in the professional competencies model, specified in terms of curricula, profiles, levels, school activities, evaluation, concept of progress and social consequences. This paradigm does not foster real progress-defined as the primacy of values sustaining spiritual, intellectual and moral development but as an "accomplice" of the civilization's collapse.

    Part II is focused on participatory education (PE), a distinctive way to understand and practice education in contrast to passive education. The core of PE is to develop everyone's own cognitive potentialities frequently mutilated, neglected or ignored. Epistemological and experiential basis of PE are defined: the concept of incisive and creative criticism, the idea of knowledge as each person's own construct and life experience as the main focus of reflection and cognition. The PE aims towards individuals with unprecedented cognitive and creative faculties, capable of approaching a more inclusive and hospitable world. The last part criticizes the fact that medical education has remained among the passive education paradigm. The key role of cognitive aptitudes, both methodological and practical (clinical aptitude), in the progress of medical education and practice is emphasized. As a conclusion, the knowhow of education is discussed, aiming towards a better world away from human and planetary degradation. Copyright © 2017 Hospital Infantil de México Federico Gómez.

    Full Text Available In the last ages cancer became the mortal number one illness in global scale, nowadays is the obesity, which presents without any distinction of age, gender, socioeconomic level neither religion. The target of the study was to describe the corporal composition and the physical aptitude associated to health of students of Union Peruvian College – Tarapoto. The sample of the study was conformed of 318 students, both genders, between the ages from 16 to 19. The research design is no experimental descriptive. In corporal composition we obtained the (BMI body mass index and to describe the physical aptitude associated to health we take five tests: mile race, push up, trunk lift, 30 seconds abdominal, and 30 seconds Burpee. The results show that when we evaluate the BMI in the students, we obtained a 54.72% underneath the right weight, 26.73% in the right weight and an 18.55% finds between pre obese and extremely obese. The average values in males of 16 and 19 in the sum of three folds were 38.8% and 36.9%, unlike the average values displayed by female gender; however, males between 17 and 18 show the 38.5% and 36.6% indicating that they increased their average values in contrast to females. Also, in the physical aptitude test, in both genders, there is a significant increase of the average values in favor of males, except in the mile race test when, at the age of 19, females get lower performance.

    Full Text Available Introduction: Though adolescence is recognised as a critical period for smoking prevention, there is a lack of research focused on this issue in Kosovo. The aim of this study has been to examine the gender-specific factors of influence (predictors for smoking among adolescents in Pristina, Kosovo. Material and Methods: The study sample comprised 1002 adolescents at the age of 17–18 (366 boys, 636 girls, all of whom were in the school’s 12th grade. The predictors included sociodemographic variables, familial (i.e., parental monitoring, parents’ educational background, and sport-related factors. The Chi2 and forward stepwise logistic regression analyses with a dichotomous criterion (smoking vs. non-smoking were applied. Results: The incidence of smoking was high (31% and 40% smokers, including 7% and 12% daily smokers for girls and boys, respectively. The regression model revealed more frequent absence from school (odds ratio (OR: 1.544; 95% confidence interval (CI: 1.063–2.243, more unexcused school absences (OR: 1.360; 95% CI: 1.029–1.796, and frequent parental questioning (OR: 1.530; 95% CI: 1.020–2.295 to be significant predictors of smoking among boys. For girls, a higher risk of smoking was associated with lower scholastic achievement (OR: 1.467; 95% CI: 1.089–1.977, more frequent absence from school (OR: 1.565; 95% CI: 1.137–2.155, increased conflict with parents (OR: 1.979; 95% CI: 1.405–2.789, and a self-declared perception of less parental care (OR: 0.602; 95% CI: 0.377–0.962. Sports were not found to be strongly related to smoking. However, a high risk of daily smoking was found among boys who participated in team sports and subsequently quit. Conclusions: This study reinforces the need for gender- and culture-specific approaches to studying the factors that influence smoking among adolescents. Med Pr 2015;66(2:153–163

    Full Text Available Acting scientifically is a competence to be developed by medical students and expressed by them when physicians. The aim of this study was to establish the relationship between scientific aptitude in medical applicants incoming to Rosario Interamerican Open University (UAI and their academic performance in Human Genetics and Histology. Seventy four out of 102 students (29 male and 45 female filled in the aptitude scientific model (ASM designed by D’Ottavio & Bassan (1989. For both, Human Genetics and Histology, performance of the students was considered as satisfactory when they reached a minimum of 85% correct answers in their objective periodic and final examinations. Conversely, lower performance was considered as less than satisfactory. The aforementioned 74 students correctly answered 3.89 ± 1.96 of the 12 ASM problems; average for males was 4.50 ± 1.99 and that for females, 3.48 ± 1.83, (p < 0.025. Students with a satisfactory performance in Histology (n = 34 showed higher scientific aptitude 4.67 ± 2.04 compared with those (n = 40 that had a less than satisfactory one 3.02 ± 1.36 (p <0.001. Significant gender differences were registered: males (n = 14 5.42 ± 2.37 vs. (n = 15 3.20 ± 1.14, p < 0.01, and females (n = 22 4.18 ± 1.56 vs. (n = 23 2.78 ± 1.47, p < 0.01.

    To investigate gender stereotypes, demonstrated engineering aptitude, and attitudes, children (N=105) solved an engineering problem using either pastel-colored or primary-colored materials. Participants also evaluated the acceptability of denial of access to engineering materials based on gender and counter-stereotypic preferences (i.e., a boy who prefers pastel-colored materials). Whereas material color was not related to differences in female participants' performance, younger boys assigned to pastel materials demonstrated lower engineering aptitude than did other participants. In addition, results documented age- and gender-related differences; younger participants, and sometimes boys, exhibited less flexibility regarding gender stereotypes than did older and female participants. The findings suggest that attempts to enhance STEM (science, technology, engineering, and math) engagement or performance through the color of STEM materials may have unintended consequences.

    DUF1220 protein domains exhibit the greatest human lineage-specific copy number expansion of any protein-coding sequence in the genome, and variation in DUF1220 copy number has been linked to both brain size in humans and brain evolution among primates. Given these findings, we examined associations between DUF1220 subtypes CON1 and CON2 and cognitive aptitude. We identified a linear association between CON2 copy number and cognitive function in two independent populations of European descent. In North American males, an increase in CON2 copy number corresponded with an increase in WISC IQ (R2 = 0.13, p = 0.02), which may be driven by males aged 6–11 (R2 = 0.42, p = 0.003). We utilized ddPCR in a subset as a confirmatory measurement. This group had 26–33 copies of CON2 with a mean of 29, and each copy increase of CON2 was associated with a 3.3-point increase in WISC IQ (R2 = 0.22, p = 0.045). In individuals from New Zealand, an increase in CON2 copy number was associated with an increase in math aptitude ability (R2 = 0.10 p = 0.018). These were not confounded by brain size. To our knowledge, this is the first study to report a replicated association between copy number of a gene coding sequence and cognitive aptitude. Remarkably, dosage variations involving DUF1220 sequences have now been linked to human brain expansion, autism severity and cognitive aptitude, suggesting that such processes may be genetically and mechanistically inter-related. The findings presented here warrant expanded investigations in larger, well-characterized cohorts. PMID:25287832

Il s'agissait d'une étude transversale, descriptive et analytique, qui s'est déroulée à Libreville pendant la période du 4 avril 2012 au 14 juillet 2012 (soit 4 mois et 10 jours). La population d’étude concernait les candidats soumis aux épreuves d'obtention du permis de conduire. Nous avons inclus dans notre travail, les candidats, ayant donné leur consentement par écrit et exclus ceux refusant d'adhérer à l'enquête. Les variables étudiées concernaient l’âge, le sexe, la population d’étude, l'activité professionnelle, l'acuité visuelle de loin et de près, la vision des couleurs, la catégorie du permis de conduire, et l'aptitude visuelle à la conduite automobile. La saisie et l'analyse des données ont été collectées au moyen d'une fiche d'enquête standardisée; après vérification et validation, elles ont été saisies sur le logiciel Excel Windows et analysées sur le logiciel Epi Info version 3.5.1. L’âge moyen des 406 candidats était de 29 ans ± 6,65 ans avec des extrêmes allant de 17 ans à 52 ans. Les hommes représentaient 283 (69,7%) et les femmes 123 (30,3%), soit un ratio de 2,3. Les fonctionnaires étaient retrouvés dans 39,4 % des cas, suivi des élèves-étudiants dans 33,5%. Dans notre population d’étude, 71 sur 406 candidats avaient une baisse de l'acuité visuelle de loin, soit 17,5%. Dans notre série, nous avons retrouvés 34 candidats âgés de 40 ans et plus, et seulement 14 candidats (41,2%) avaient une baisse de l'acuité visuelle de près.

    Cultivating research culture at an early stage is important for capacity building in a community. The high school level is the appropriate stage for research to be introduced because of students' competitive nature. Participation in the space weather competition is one of the ways in which research aptitude can be fostered in high school students in Malaysia. Accordingly, this paper presents how research elements were introduced to the students at the high school level through their participation in the space weather competition. The competition required the students to build a system to detect the presence of solar flares by utilizing VLF signals reflected from the ionosphere. The space weather competition started off with proposal writing for the space weather related project where the students were required to execute extensive literature review on the given topic. Additionally, the students were also required to conduct the experiments and analyse the data. Results obtained from data analysis were then validated by the students through various other observations that they had to carry out. At the end of the competition, students were expected to write a comprehensive technical report. Through this competition, the students learnt how to conduct research in accordance to the guidelines provided through the step by step approach exposed to them. Ultimately, this project revealed that the students were able to conduct research on their own with minimal guidance and that participation in the competition not only generated enjoyment in learning but also their interest in science and research.

    Full Text Available Approach and avoidance are two basic behavioral aptitudes of humans whose correct balance is critical for successful adaptation to the environment. As the expression of approach and avoidance tendencies may differ significantly between healthy individuals, different psychobiological factors have been posited to account for such variability. In this regard, two main issues are still open that refers to i the role played by dopamine neurotransmission and ii the possible influence of cognitive characteristics, particularly executive functioning. The aim of the present paper was to highlight the contribution of research on Parkinson’s disease (PD to our understanding of the above issues. In particular, we here reviewed PD literature to clarify whether neurobiological and neuropsychological modifications due to PD are associated to changes in approach-avoidance related personality features. Available data indicate that PD patients may show and approach-avoidance imbalance as documented by lower novelty-seeking and higher harm-avoidance behaviors, possibly suggesting a relationship with neurobiological and neurocognitive PD-related changes. However, the literature that directly investigated this issue is still sparse and much more work is needed to better clarify it.

    Rail system is a system that is very closely related to the public life. When an accident happens, the public using this system should be injured or even be killed. The accident that recently took place in Taegu subway system, because of the inappropriate human-side task performance, showed demonstratively how its results could turn out to be tragic one. Many studies have shown that the most cases of the accidents have occurred because of performing his/her tasks in inappropriate way. It is generally recognised that the rail system without human element could never be happened quite long time. So human element in rail system is going to be the major factor to the next tragic accident. This state of the art report studied the cases of the managements and evaluation systems related to human errors, license requirements, and job aptitudes in the areas of rail and the other industries for the purpose of improvement of the task performance of personnel which consists of an element and finally enhancement of rail safety. The human errors, license requirements, and evaluation system of the job aptitude on people engaged in agencies with close relation to rail do much for development and preservation their abilities. But due to various inside and outside factors, to some extent it may have limitations to timely reflect overall trends of society, technology, and a sense of value. Removal and control of the factors of human errors will have epochal roles in safety of the rail system through the case studies of this report. Analytical results on case studies of this report will be used in the project 'Development of Management Criteria on Human Error and Evaluation Criteria on Job-aptitude of Rail Safe-operation Personnel' which has been carried out as a part of 'Integrated R and D Program for Railway Safety'.

Multi-stage simple random sampling was used to select participants. At the end of their high school education, 980 adolescents (623 females ages 17 to 19 years old were enrolled in the study. The prevalence of smoking, alcohol consumption (measured by Alcohol Use Disorder Identification Test–AUDIT, and illegal drug use (dependent variables, as well as socio-demographic, scholastic, familial, and sports-related factors (independent variables, were assessed. Boys smoke cigarettes more often than girls with daily-smoking prevalence of 16% among boys and 9% among girls (OR = 1.85, 95% = CI 1.25–2.75. The prevalence of harmful drinking (i.e., AUDIT scores of >10 is found to be alarming (41% and 37% for boys and girls, respectively; OR = 1.13, 95% CI = 0.87–1.48, while 17% of boys and 9% of girls used illegal drugs (OR = 2.01, 95% CI = 1.35–2.95. The behavioral grade (observed as: excellent–average-poor is the factor that was most significantly correlated with SUM both in boys and girls, with lower behavioral grades among those adolescents who consume substances. In girls, lower maternal education levels were associated with a decreased likelihood of SUM, whereas sports achievement was negatively associated with risky drinking. In boys, sports achievement decreased the likelihood of daily smoking. Information on the factors associated with SUM should be disseminated among sports and school authorities.

Verificou-se a existência de disfunções e influência da idade no nível da atenção, e ainda a existência de relação entre os déficits atencional e motor. Quanto mais baixo o nível de atenção, pior é a aptidão motora.OBJECTIVE: To evaluate the general and specific motor aptitude and attention in patients with major depressive disorder (MDD. METHODS: Sixteen women admitted in a psychiatric hospital answered to a clinic and socio-demographic interview. For the evaluation it was used the Motor Scale for the Elderly (Escala Motora para Terceira Idade - EMTI and the Trail Making Test (TMT. RESULTS: The average age of women was 38,63 years old, and the first diagnostic was made on average of 32,81 years old; they also have a low family income. At the general motor aptitude, 56,25% of the patients were classified as "below average", 37,5% as "normal medium" and 6,25% as

    Full Text Available Este trabajo presenta algunas preguntas y desarrollos preliminares surgidos en un recorrido teórico realizado por los textos freudianos del término "aptitud". - Se presentan las referencias a textos anteriores a 1920, aunque se privilegie, en función de los objetivos de la investigación en curso, el ordenamiento y relación de la "aptitud de analista" con los conceptos fundamentales de la segunda tópica freudiana. ¿Se puede elevar el término castellano aptitud y sus originales alemanes al estatuto de un concepto? Finalmente se planteará que la dimensión pulsional del término es lo que permite darle a la "aptitud de analista" un estatuto conceptual, ya que la aptitud como "tauglich" en el advenimiento de un nuevo analista implica una transmutación pulsional específica. La pregunta por cuál es la relación entre lo que porta el carácter y la recomposición de las alteraciones del yo en el período posterior al análisis quedará como orientación para otro trabajo.This work presents some questions and preliminary developments which erased during the theoretical examinations realized on the Freud's texts concerning the term ¨competence¨. The references to the texts earlier than 1920 are given, however, in function of the objectives of the investigation in course, the order and relation of the ¨analyst' s competence¨ to the fundamental concepts of Freud's second topography are favored. Can we give a Spanish term ¨aptitud¨ and its German originals a status of a concept? Final consideration will be that the instinctual dimension of the term is what permits to give it a conceptual status to the ¨analyst's competence¨, since ¨competence¨ as ¨tauglich¨ in making a new analyst implies a specific instinctual transmutation. The question about what is the relation between what makes a character and the reparation of the alteration of ¨I ¨ in the period following the analysis will remain an orientation for further work.

    Full Text Available The object of this study was to compare two methods for determining the aptitude of soils for growing Sugarcane in Cuba. The information was provided by three sugarcane farms owned by Ciudad Caracas sugarcane mill in the municipality of Santa Isabel de Las Lajas in Cienfuegos. The information of the soils from each farm was taken from the 1:25 000 scale cadastral maps designed by Ministerio de la Agricultura (MINAG. Rainfall data was collected from the nearby stations rain gauges. And the sugarcane yield was reported by each farm. The aptitude of the soils was determined by two methods (AGRO 24 de 1993 y Arzola de 1999 using the information available. Results showed that both methods are appropriate for selecting soils with higher productive potential, and are a useful tool for making right decisions for optimizing the land use at each sugarcane farm.

  11. Measuring students' self-regulated learning in professional education: bridging the gap between event and aptitude measurements.

    Endedijk, Maaike D; Brekelmans, Mieke; Sleegers, Peter; Vermunt, Jan D

    Self-regulated learning has benefits for students' academic performance in school, but also for expertise development during their professional career. This study examined the validity of an instrument to measure student teachers' regulation of their learning to teach across multiple and different kinds of learning events in the context of a postgraduate professional teacher education programme. Based on an analysis of the literature, we developed a log with structured questions that could be used as a multiple-event instrument to determine the quality of student teachers' regulation of learning by combining data from multiple learning experiences. The findings showed that this structured version of the instrument measured student teachers' regulation of their learning in a valid and reliable way. Furthermore, with the aid of the Structured Learning Report individual differences in student teachers' regulation of learning could be discerned. Together the findings indicate that a multiple-event instrument can be used to measure regulation of learning in multiple contexts for various learning experiences at the same time, without the necessity of relying on students' ability to rate themselves across all these different experiences. In this way, this instrument can make an important contribution to bridging the gap between two dominant approaches to measure SRL, the traditional aptitude and event measurement approach.

Se trabajó en tres escuelas públicas del Distrito Federal, México. Se utilizó un muestreo no probabilístico, intencional, participaron 670 niños (Medad = 9.18, DE = .997, 356 mujeres y 314 hombres. También, colaboraron 24 docentes, 21 mujeres y 3 hombres (Medad = 43 años. Se aplicaron el Test de Matrices Progresivas Raven, Prueba de Pensamiento Creativo de Torrance, Escala de Compromiso con la Tarea, Prueba de Autoconcepto Académico y Lista de Nominación. Se identificaron 34 niños con perfil sobresaliente, quienes obtuvieron puntuaciones por encima del percentil 75 en por lo menos tres de las cinco pruebas, los cuales se distribuyeron en tres grupos de acuerdo con la cantidad de variables con estimaciones superiores. La U de Mann Whitney mostró que no había diferencia entre las variables con respecto al sexo, se observó que los niños de mayor edad eran más creativos. La prueba Kruskal-Wallis reportó diferencias significativas entre los tres grupos en la creatividad, compromiso con la tarea, autoconcepto académico y en la nominación del maestro. La correlación de Spearman mostró asociaciones positivas y significativas, entre la edad y la creatividad; y el compromiso con la tarea con el autoconcepto académico. Se concluye que los alumnos sobresalientes forman parte de un grupo heterogéneo, por lo que es necesario considerar diferentes variables para evaluarlos y determinar sus necesidades educativas.

    Consistently with the involvement of affective temperaments in professional choices, our research team is aiming to outline the temperamental profile of subjects who are applying to enter a military career in the Italian Armed Forces. In this study we aim to verify the importance of temperamental traits not only in choosing the military career as a profession, but also in passing or failing the entrance examinations. We compared the affective temperaments (evaluated by TEMPS-A[P]) of those applying to become a cadet officer in the Italian Navy, divided into various subgroups depending on whether they passed or failed the entrance examination at various levels (high school final test, medical (physical and psychiatric), mathematical examination and aptitude test). We also tested for correlations between grades received and temperamental scores. Higher scores for those with a hyperthymic and lower scores for those with a depressive, cyclothymic or irritable temperament characterized applicants taking medical exams and aptitude tests. Higher scores on the high school final test correlated with lower hyperthymic, cyclothymic and irritable temperament scores. No correlations were found between temperamental traits and mathematical examinations. Multivariate analysis stressed the negative impact of a cyclothymic temperament and the poor discriminant power of temperaments regarding medical and mathematical examinations, and aptitude tests. Conversely, temperaments showed good discriminant power as far as psychiatric examinations are concerned. Hyperthymic temperamental traits appear to be important not only in choosing a profession, but also in passing entrance examinations. Even so, affective temperaments (strong hyperthymic and weak cyclothymic, depressive and irritable traits) are the only successfully predictors of the outcome of psychiatric examinations and, to a lesser extent, medical examinations and aptitude tests.

    The purpose of this article is to show that experimental scientific methods can be applied to explain how the analytic mechanism of the left cerebral hemisphere and the synthetic mechanism of the right one create complex cognitive constructions like ontology and mathematics. Nominalism and ordinal mathematical concepts are related to the analytic left hemisphere while Platonism and cardinal mathematical concepts are related to the synthetic right one. Thus persons with a dominant left hemisphere tend to prefer nominalist ontology and have more aptitude for ordinal mathematics than for cardinal mathematics, while persons with a dominant right hemisphere tend to prefer platonist ontology and have more aptitude for cardinal mathematics than for ordinal mathematics. It is further explained how the Kantism temporal mode of perceiving experience can be related to the left hemisphere while the Kantian spatial mode of perceiving experience can be related to the right hemisphere. This relation can be tested experimentally, thus the Kantian source of constructivism, and through it constructivism itself, can be tested experimentally.

    Malnutrition is a serious problem among children in developing countries. In India; a school meal program is in place to combat malnutrition, but only in government schools. This study is an attempt to assess the prevalence of malnutrition in primary and secondary school children in private schools and to also assess the relationship between malnutrition and academic performance. All 582 students from class 1-7 from two select schools in rural Bangalore, India were included in the study. Information on age of study subjects were collected from school records. Height and weight measurements were taken. BMI was calculated. Children were clinically examined for pallor. Data on height, weight and BMI was transformed into WHO 2007 Z scores and then was categorized as -2 SD, > 2 SD. Mathematics and English scores of the previous two class tests were taken, average scores were calculated. Statistical tests used were Chi square test, Odd's ratio, Chi square for trend. A total of 582 students participated in this study. Males were 54% (315) and females were 46% (267). One hundred and fifty-nine (27%) of the children had pallor, 81 (20%) had under nutrition, 38 (7%) had stunting, 197 (34%) had thinness and 5 (1%) were found to be obese. Positive relationship was found between weight for ageZscores and English as well as Maths; Height for age Z scores with English. Hence we conclude that the prevalence of malnutrition is high among children in private schools also; and the nutritional status of the children is strongly associated with their academic performance.

Con el fin de evaluar la repetibilidad en la medición, cada analista repitió entre 6 y 10 veces la calibración con cada pipeta. Se evaluó la media aritmética de las mediciones de cada analista para cada pipeta y se estimó su incertidumbre expandida. Aquí se presentan los gráficos con las medias y las incertidumbres obtenidas para cada tipo de pipeta y se efectúa un estudio comparativo de los resultados. A modo de conclusión se evaluó la reproducibilidad de cada tipo de instrumento, en base a lo cual se formulan recomendaciones para su uso y calibración.AbstractIn 2008 several chemical analysts from LATU’s test laboratories (most of them new to their task took part in a Proficiency Test for the use of volumetric glassware. Two pipettes were used: a glass pipette of 1 ml, class B, and an automatic pipette of variable volume between 0 ml and 1 ml. The latter was calibrated at 1 ml. All analysts were asked to repeat each calibration between 6 and10 times to allow an estimate of the measurement repeatibility. The average value performed by each analyst for each pipette was evaluated and its uncertainty estimated. Graphs are presented showing the analysts’ means and uncertainties for each pipette and the results are compared. As a conclusion, the reproducibility of each kind of instrument is evaluated according to which recommendations are given for the calibration and use of the two types of pipette.

    2011-05-01

    Climate has an obvious influence on tourism as a resource and as a location factor for tourist activities. Consequently, the tourist phenomenon in general is heavily controlled by meteorological conditions—in short, by the climate. In this article, the author proposes a set of weather types with which to establish the climate aptitude for sun and beach tourism. To determine these types, the density of use of one of the beaches with the lowest seasonality in continental Europe, the Levante Beach in Benidorm (Alicante, Spain), was analysed. Beach attendance was monitored using a webcam installed by the "Agencia Valenciana de Turismo". The relationship between the density of use of the lower and upper beach areas on the one hand, and meteorological variables on the other, allowed comfort (physiological equivalent temperature) and enjoyment (fractions of solar radiation) thresholds to be established. The appropriate hydric comfort values were obtained by comparing the ranges proposed by Besancenot in 1989 [Besancenot (1989) Clima et turismes. Massom, París] with numbers of visitors to the beach. The wind velocity and precipitation thresholds were selected following consultation with the literature and considering the climatic characteristics of the environment under analysis. Based on a combination of these thresholds, weather types suitable for this specific tourist activity are defined. Thus, this article presents a method for assessing the extent to which a day on the beach can be enjoyed. This has a number of applications, for planners, the tourism business and consumers alike. The use of this (filter) method in climate databases and meteorological forecasts could help determine the tourist season, the suitability of setting up a business associated with sun and beach tourism, as well as help plan holidays and program a day's leisure activities. Thus, the article seeks to improve our understanding of the climate preferences of that tourist activity par

    How do joint measures of premorbid cognitive ability and familial cognitive aptitude (FCA) reflect risk for a diversity of psychiatric and substance use disorders? To address this question, we examined, using Cox models, the predictive effects of school achievement (SA) measured at age 16 and FCA-assessed from SA in siblings and cousins, and educational attainment in parents-on risk for 12 major psychiatric syndromes in 1 140 608 Swedes born 1972-1990. Four developmental patterns emerged. In the first, risk was predicted jointly by low levels of SA and high levels of FCA-that is a level of SA lower than would be predicted from the FCA. This pattern was strongest in autism spectrum disorders and schizophrenia, and weakest in bipolar illness. In these disorders, a pathologic process seems to have caused cognitive functioning to fall substantially short of familial potential. In the second pattern, seen in the internalizing conditions of major depression and anxiety disorders, risk was associated with low SA but was unrelated to FCA. Externalizing disorders-drug abuse and alcohol use disorders-demonstrated the third pattern, in which risk was predicted jointly by low SA and low FCA. The fourth pattern, seen in eating disorders, was directly opposite of that observed in externalizing disorders with risk associated with high SA and high FCA. When measured together, adolescent cognitive ability and FCA identified four developmental patterns leading to diverse psychiatric disorders. The value of cognitive assessments in psychiatric research can be substantially increased by also evaluating familial cognitive potential.

    As a result of studies examining factors involved in the learning process, various structural models have been developed to explain the direct and indirect effects that occur between the variables in these models. The objective was to evaluate a structural model of cognitive and motivational variables predicting academic achievement, including general intelligence, academic self-concept, goal orientations, effort and learning strategies. The sample comprised of 341 Spanish students in the first year of compulsory secondary education. Different tests and questionnaires were used to evaluate each variable, and Structural Equation Modelling (SEM) was applied to contrast the relationships of the initial model. The model proposed had a satisfactory fit, and all the hypothesised relationships were significant. General intelligence was the variable most able to explain academic achievement. Also important was the direct influence of academic self-concept on achievement, goal orientations and effort, as well as the mediating ability of effort and learning strategies between academic goals and final achievement.

    Full Text Available Musical taste has been a research focus in sociology, not in the way it is acquired in school, but how primary groups, e.g. family or peer groups, have influenced it. In this article we have used the Survey of Social Reality in Andalusia (2009 with the aim of showing the role played by individuals social characteristics on their music consumption patterns. Our results have showed that there is no a exclusive consumption pattern of high culture linked to a social milieu. Through a latent class analysis, we have found three consumption patterns: ‘omnivore’, ‘modern’ and ‘traditional univore’, distinguishing by educational level, age and social origin. Thus, the voraciousness of musical genres is the result of a combination of factors such as educational attainment, life cycle and intergenerational transmission of cultural skills and attitudes, and not by the achievement of prestige or social class.

    El gusto musical ha sido objeto de estudio privilegiado de la sociología, no tanto por la manera en que es adquirido en la escuela, sino por el modo en que los grupos primarios, como la familia o los grupos de pares, han ejercido su influencia. En el presente artículo hemos utilizado la Encuesta sobre la Realidad Social en Andalucía (2009 con el objetivo de mostrar el papel que juegan un conjunto de características sociales de los individuos en su patrón de consumo de música. Nuestros resultados han evidenciado que no existe un patrón de consumo exclusivo de alta cultura ligado a un estrato social. A través de un análisis de clases latentes, hemos encontrado tres patrones de consumo: ‘omnívoro’, ‘moderno’ y ‘unívoro tradicional’, distinguiéndose por el nivel educativo, la edad o el origen social. La voracidad de géneros musicales, por tanto, es fruto de una combinación de factores como el logro educativo, el ciclo de vida y la transmisión intergeneracional de aptitudes y actitudes culturales, pero no así de

La base cartográfica fue conformada a partir de imágenes satelitales en combinación con mapas de elaboración acerca de unidades geomorfológicas, provincias fitogeográficas, hidrografía y áreas con evidencia arqueológica de agricultura prehispánica. Se observó que el área con mayor potencial para la agricultura se ubica en el sector pedemontano de la sierra del Aconquija, seguido por el fondo de valle. Este patrón coincide principalmente con el registro arqueológico prehispánico, pero no con la distribución espacial de las explotaciones agrícolas actuales. La relación entre la sociedad y la naturaleza, mediatizada a través de la tecnología, se presenta como la clave de interpretación. ABSTRACT This study was performed with the objective to identify suitable areas for development of pre-Hispanic and contemporary agriculture in Santa Maria Valley (Catamarca, Argentina through the application of multicriteria evaluation techniques using Geographic Information Systems. The base map was based on data obtained from satellite images in combination with thematic maps specially prepared about geomorphological units, phytogeographic provinces, hydrography and areas with archaeological evidence of prehispanic agriculture. It was observed that the area with the greatest potential for agriculture is located in the piedmont sector of the Aconquija mountain, followed by the bottom of the valley. This pattern coincides mainly with the pre-Hispanic archaeological record, but not with the spatial distribution of existing farms. The relationship between society and nature, mediated through technology, is presented as the key to interpretation

    Full Text Available The kindergarten teachers must be aware of the importance of the acquisition of social skills for children, with a view to appropriate adaptation and overcoming the various challenges that will have those throughout existence. This article is the presentation of a research work within the pre-school educational context, in the field of ʻSocial and Personal Educationʼ which may lead to improved social skills within the group of children. In order to accomplish this, after the teaching training with the pre-school class which focussed on the acquisition of social competence, an assessment of the modified social skills within the class was carried out. These activities were included in the preschool lesson planning during the ʻSupervised Teaching Practiceʼ. They were developed based on childrenʼs daily life situations, focussing mainly on using games in the learning contexts. The aim of these games was to motivate and involve the children in order to enhance their balanced social development. The results obtained suggest that the introduction of this type of learning activities may be an asset in Pre-school Education because they develop both childrenʼs social skills and social competence. Moreover, this type of learning activities may also lead to changes in childrenʼs social interaction with both adults and their peers which may favour pro social behaviour.

    We developed and validated an echo simulator with three novel tools that facilitate training and enable quantitative and objective measurement of psychomotor as well as cognitive skill. First, the trainee can see original patient images - not synthetic or simulated images - that morph in real time as the mock transducer is manipulated on the mannequin. Second, augmented reality is used for Visual Guidance, a tool that assists the trainee in scanning by displaying the target organ in 3-dimensions (3D) together with the location of the current view plane and the plane of the anatomically correct view. Third, we introduce Image Matching, a tool that leverages the aptitude of the human brain for recognizing similarities and differences to help trainees learn to perform visual assessment of ultrasound images. Psychomotor competence is measured in terms of the view plane angle error. The construct validity of the simulator for competency testing was established by demonstrating its ability to discriminate novices vs. experts.

    Full Text Available A psychological test is a test that is designed to measure one aspect of human behavior. These tests are usually designed to evaluate a person’s ability to complete tasks that were individual's performance on certain tasks that have usually been requested in advance. Usually a test score is used to compare with other results to measure the individual’s performance regarding cognitive ability, aptitude, personality, etc. One such test is the so called “finger tapping” test, designed to measure the integrity of the neuromuscular system and examine motor control. There are several ways to perform such a test. The purpose of this paper isn’t to study the finger tapping test which is well documented in the literature, but to develop if possible a simple way of performing such a test. Using the method presented in the paper a nonstationary signal was obtained and it was analyzed using the Short-time Fourier time frequency representation to obtain the signals frequency and its variation in time. The results presented in the paper show that this method can be used to perform the test and the frequency and spatial amplitude of the obtained tapping signal can be determined easily.

    Proposal of an innovative approach to clarify the mechanism through which poor cognitive performance in adolescence impacts risk for schizophrenia (SZ). To determine whether the developmental processes that predispose to SZ are better reflected by the observed cognitive performance in adolescence or the deviation of that performance from the individual's familial cognitive aptitude (FCA). A prospective cohort design. Risk for SZ and bipolar illness (BPI) are predicted by school achievement (SA) at age 16 years and IQ at ages 18 to 20 years and the deviation of that performance from an individual's FCA. Familial cognitive aptitude is calculated from the SA, IQ, and educational attainment in biological relatives. Diagnoses of SZ or BPI in the Swedish Hospital Discharge Register and the Swedish Outpatient Register. Participants were 996 886 individuals with recorded SA and 106 187 individuals with recorded IQ born in Sweden between January 1, 1972, and December 31, 1990, with sufficient numbers of biological relatives to calculate their FCA. The first cohort is 48.7% female, and the second is all male. Risk for SZ was strongly predicted by the deviation of SA from the FCA (hazard ratio [HR], 0.56; 95% CI, 0.49-0.63) but not with the observed SA (HR, 1.01; 95% CI, 0.91-1.13). Similar results were obtained for IQ (HR, 0.53; 95% CI, 0.37-0.77 for the deviation from the FCA and HR, 1.07; 95% CI, 0.78-1.46 for the observed IQ). After matching SZ and control probands on cognitive performance, the siblings of the SZ probands had SA and IQs that did not differ from population means and were significantly higher in cognitive performance than for the siblings of control probands. Correlations in SA and IQs between the pre-SZ probands and their siblings were significantly lower than those observed between the matched control probands and their siblings. Risk for BPI was more weakly predicted by deviations from the FCA. No differences were found in the SA and IQs of siblings

    The study of the evolutions of different wine pigment families, copigmentation/polymerisation processes and colour characteristics during the first year of ageing in oak barrel has allowed the assessment of the ageing aptitude of Syrah wines from "Condado de Huelva D.O.", a warm climate region. A total of 32 anthocyanic pigments were identified, including 14 major compounds from grape and 18 minor derivatives formed during the vinification. The anthocyanin profile changed towards more chemical complexity, being vitisin-like pyranoanthocyanins the predominant minor pigments during the first month of ageing. As wine became older, a progressive increase on the content of 4-vinylcatechin, 4-vinylphenol and 4-vinylcatechol compounds took place. Results showed that copigmentation occurred during the whole process of ageing inducing visual perceptible colour effects. Simultaneously to the copigmentation decrease, the degree of polymerisation increased during ageing, being maximum at 9 months old wines (77%). The colour of wines evolved progressively in a positive way from 3 to 9 months of ageing, becoming darker and with more vivid colour. However, from 9 to 12 months of ageing, the chemical structure of wines was negatively affected resulting in lighter, with more red-orange hues and less vivid colours. The inclusion of the chemical and colorimetric information on the PCA model allows us to reach very good discriminations among the Syrah wines with different wood contact period.

    Neuropsychological sex differences have since long been under debate. Support for the relation between behavioral differences and biological variables like hormone influence is, however, emerging. Sixteen men and sixteen women, all university students, were tested with computerized neuropsychological tests (APT), the Bem Sexual Role Inventory, and asked about pubertal age. The results were in line with earlier findings of sex differences in neuropsychological tests, men being faster and women more cautious. The assumption that women tend to use left-hemispheric, verbal/serial strategies also in spatial tasks was also partly supported. In women, late onset of puberty was related to better spatial performance, and there were also more intercorrelations between verbal and spatial tests in the female than in the male group, indicating that women use less specific strategies (more g-factor intelligence) in problem solving, or that aptitudes are less compartmentalized in women than in men.

    2018-04-01

    Full Text Available The practice of Significance Testing (ST remains widespread in psychological science despite continual criticism of its flaws and abuses. Using simulation experiments, we address four concerns about ST and for two of these we compare ST’s performance with prominent alternatives. We find the following: First, the 'p' values delivered by ST predict the posterior probability of the tested hypothesis well under many research conditions. Second, low 'p' values support inductive inferences because they are most likely to occur when the tested hypothesis is false. Third, 'p' values track likelihood ratios without raising the uncertainties of relative inference. Fourth, 'p' values predict the replicability of research findings better than confidence intervals do. Given these results, we conclude that 'p' values may be used judiciously as a heuristic tool for inductive inference. Yet, 'p' values cannot bear the full burden of inference. We encourage researchers to be flexible in their selection and use of statistical methods.

    Limited time dedicated to each training areas, irrelevant case-studies, and ethics "checklists" have resulted in bare-bones Responsible Conduct of Research (RCR) training for present biomedical graduate student researchers. Here, we argue that science graduate students be taught classical ethical theory, such as virtue ethics, consequentialist theory, and deontological theory, to provide a basic framework to guide researchers through ethically complex situations and examine the applicability, implications, and societal ramifications of their research. Using a relevant biomedical research example to illustrate this point, we argue that proper ethics training for graduate student researchers not only will enhance current RCR training, but train more creative, responsible scientists.

  9. Space Architecture: The Role, Work and Aptitude

    Science.gov (United States)

    Griffin, Brand

    2014-01-01

    Space architecture has been an emerging discipline for at least 40 years. Has it arrived? Is space architecture a legitimate vocation or an avocation? If it leads to a job, what do employers want? In 2002, NASA Headquarters created a management position for a space architect whose job was to "lead the development of strategic architectures and identify high level requirements for systems that will accomplish the Nation's space exploration vision." This is a good job description with responsibility at the right level in NASA, but unfortunately, the office was discontinued two years later. Even though there is no accredited academic program or professional licensing for space architecture, there is a community of practitioners. They are civil servants, contractors and academicians supporting International Space Station and space exploration programs. In various ways, space architects currently contribute to human spaceflight, but there is a way for the discipline to be more effective in developing solutions to large scale complex problems. This paper organizes contributions from engineers, architects and psychologists into recommendations on the role of space architects in the organization, the process of creating and selecting options, and intrinsic personality traits including why they must have a high tolerance for ambiguity.

  1. How do gloves affect cutaneous sensibility in medical practice? Two new applied tests.

    Science.gov (United States)

    Mylon, Peter; Carré, Matt J; Martin, Nicolas; Lewis, Roger

    2017-01-01

    In order to quantify the effect of medical gloves on tactile performance, two new Simulated Medical Examination Tactile Tests (SMETT) have been developed to replicate the tactile and haptic ability required in medical examinations: the 'Bumps' test and the 'Princess and the Pea' (P&P) test. A pilot study was carried out using 30-40 subjects for each test in order to investigate the suitability of the tests for medical glove evaluation. Tests were performed with latex and nitrile examination gloves and without gloves. Following the tests, small-scale studies were carried out to investigate the effect of various design parameters, such as material stiffness and tactile exploration method. In the 'Bumps' test, subjects performed significantly better in the ungloved condition, and there were 'almost significant' differences between the gloves, with the thinner latex gloves performing better than the thicker nitrile gloves. Both finger orientation and surface lubrication were found to have a significant effect on results, indicating that these need to be clearly defined in the test procedure. In the 'P&P' test, no significant effect of hand condition was found, suggesting that haptic sensing is less affected by medical gloves than cutaneous sensibility. Other factors such as material stiffness, technique and test orientation had a more significant effect. The SMETT 'Bumps' test has potential as a clinical manual performance evaluation tool and may be used to evaluate the relative effects of different gloves. The SMETT 'P&P' test is a valid measure of haptic or tactile performance, but should not be used in glove evaluation. Both tests could have further applications, such as in the assessment of neurological impairment or aptitude testing for potential surgeons.

  3. The predictive validity of the BioMedical Admissions Test for pre-clinical examination performance.

    Science.gov (United States)

    Emery, Joanne L; Bell, John F

    2009-06-01

    Some medical courses in the UK have many more applicants than places and almost all applicants have the highest possible previous and predicted examination grades. The BioMedical Admissions Test (BMAT) was designed to assist in the student selection process specifically for a number of 'traditional' medical courses with clear pre-clinical and clinical phases and a strong focus on science teaching in the early years. It is intended to supplement the information provided by examination results, interviews and personal statements. This paper reports on the predictive validity of the BMAT and its predecessor, the Medical and Veterinary Admissions Test. Results from the earliest 4 years of the test (2000-2003) were matched to the pre-clinical examination results of those accepted onto the medical course at the University of Cambridge. Correlation and logistic regression analyses were performed for each cohort. Section 2 of the test ('Scientific Knowledge') correlated more strongly with examination marks than did Section 1 ('Aptitude and Skills'). It also had a stronger relationship with the probability of achieving the highest examination class. The BMAT and its predecessor demonstrate predictive validity for the pre-clinical years of the medical course at the University of Cambridge. The test identifies important differences in skills and knowledge between candidates, not shown by their previous attainment, which predict their examination performance. It is thus a valid source of additional admissions information for medical courses with a strong scientific emphasis when previous attainment is very high.

This paper explores the concept of test quality and its relationship with operational readiness and preventive maintenance. This paper also considers the frequencies of component testing. Test quality is related to a test's ability to detect degradation that can cause component failure. The quality of the test depends on several factors, including specific parameters measured, system or component conditions, and instrument accuracy. The quality of some currently required tests for check valves, motor-operated valves, and pumps is also discussed. Suggestions are made to improve test quality by measuring different parameters, testing valves under load, and testing positive displacement pumps at high pressure and centrifugal pumps at high flow rate conditions. These suggestions can help to improve the level of assurance of component operational readiness gained from testing

    For the proper performance of ultrasonic testing of steel welded joints, and anisotropic material it is necessary to have sound understanding on the underlying physics. To provide such an understanding, it is beneficial to have simulation tools for ultrasonic testing. In order to address such a need, we develop effective approaches to simulate angle beam ultrasonic testing with a personal computer. The simulation is performed using ultrasonic measurement models based on the computationally efficient multi-Gaussian beams. This reach will describe the developed ultrasonic testing models together with the experimental verification of their accuracy.

    Full Text Available The basic goal of this study was to analysis of the results of the 30-m running speed test in soccer players in third soccer leagues. The study examined the group of randomly selected seventy athletes from two soccer teams from the Ekstraklasa league, two teams from the first league and two teams from the second leagues were randomized into the study group. All the measurements were performed in indoor arenas. The temperature in the arenas ranged from 22 to 24 C. Measurements were recorded in the morning (between 10:00 am and 12:00 am. The Running Speed Test was used in the study to diagnose speed potential in the athletes. The running speed was measured by means of a set of photocells located at 0m, 5m, 20m, 30m. The results obtained demonstrated that the elite-level matches are more dynamic since the players show higher values of speed parameters. Apart from starting speed, the results obtained for the distance of 5 m provide information for coaches concerning their work on special strength. The speed is indicated by the results obtained for 20 and 30 m distances, whereas flying measurements between 5/20m and 20/30m reflect inherited speed aptitudes.

    Full Text Available The study tries to investigate the utilization of intellectual creative skills within the framework of the triarchic theory of intelligence in reading activities. The subject in which the theory was applied was Bahasa Indonesia (Indonesian. This experimental study involved randomly selected seventh graders of Junior High School. There were three hypotheses to test in the study. First, the order of the three types of intellectual skills suggested in the triarchic theory of intelligence presented during training as well as during instruction has effects on students' performance in attempting creative solution to problems derived from reading texts in the subject of Bahasa Indonesia. Multiple comparisons were employed to test this hypothesis. Second, there is a significant difference in creative problem solving performances between the experimental and the control groups. Analysis of variance was carried out to test this hypothesis. Third, scholastic aptitude has a role in predicting the creative problem solving performance. ANACOVA was employed to test this hypothesis. The results show that the students show the best performance when they are trained using the thinking order of practice-synthesis-analysis.

    In the 1950s, most of the men who witnessed Britain's nuclear tests at Christmas Island in the Pacific were national servicemen, aged 19 or 20. Some revelled in sun and swimming, some were bored, some were too busy to be bored. How many of the twenty thousand servicemen involved in the tests suspected that they might be exposed to radiation that would reveal itself a generation later in blood and bone cancers, sterility, cataracts, or deformities in their children. The Ministry of Defence insists nobody was in danger. This book tells a different story, in the words of the servicemen, and of their medical reports, about secrets which are no longer Official. It is important not only to the victims of a government's extraordinary reluctance to face up to the tragic consequences of a programme of nuclear tests on Christmas Island and in Australia, but to anyone concerned with the damage that nuclear testing is still doing in the world today.

The injection tests allowed debugging and improvement in appropriate portions to allow safe, efficient and state-of-the-art commissioning later on. The usefulness of such an approach for a successful start-up becomes obvious when looking at the problems we encountered before and during the injection tests and could solve during this period. The outline of the preparation and highlights of the different injection tests will be presented and the excellent performance of many tools discussed. A list of shortcomings will follow, leading to some planning for the preparation of the run in 2009.

    Neuropsychological testing is a key diagnostic tool for assessing people with dementia and mild cognitive impairment, but can also help in other neurological conditions such as Parkinson's disease, stroke, multiple sclerosis, traumatic brain injury and epilepsy. While cognitive screening tests offer gross information, detailed neuropsychological evaluation can provide data on different cognitive domains (visuospatial function, memory, attention, executive function, language and praxis) as well as neuropsychiatric and behavioural features. We should regard neuropsychological testing as an extension of the neurological examination applied to higher order cortical function, since each cognitive domain has an anatomical substrate. Ideally, neurologists should discuss the indications and results of neuropsychological assessment with a clinical neuropsychologist. This paper summarises the rationale, indications, main features, most common tests and pitfalls in neuropsychological evaluation. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    2007-01-01

    The Hubbert theory of oil depletion, which states that oil production in large regions follows a bell-shaped curve over time, has been cited as a method to predict the future of global oil production. However, the assumptions of the Hubbert method have never been rigorously tested with a large, publicly available data set. In this paper, three assumptions of the modern Hubbert theory are tested using data from 139 oil producing regions. These regions are sub-national (United States state-level, United States regional-level), national, and multi-national (subcontinental and continental) in scale. We test the assumption that oil production follows a bell-shaped curve by generating best-fitting curves for each region using six models and comparing the quality of fit across models. We also test the assumptions that production over time in a region tends to be symmetric, and that production is more bell-shaped in larger regions than in smaller regions

    2007-08-01

    This study analyzes the correlation between video game usage and academic performance. Scholastic Aptitude Test (SAT) and grade-point average (GPA) scores were used to gauge academic performance. The amount of time a student spends playing video games has a negative correlation with students' GPA and SAT scores. As video game usage increases, GPA and SAT scores decrease. A chi-squared analysis found a p value for video game usage and GPA was greater than a 95% confidence level (0.005 video game usage also returned a p value that was significant (0.01 video games may have a detrimental effect on an individual's GPA and possibly on SAT scores. Although these results show statistical dependence, proving cause and effect remains difficult, since SAT scores represent a single test on a given day. The effects of video games maybe be cumulative; however, drawing a conclusion is difficult because SAT scores represent a measure of general knowledge. GPA versus video games is more reliable because both involve a continuous measurement of engaged activity and performance. The connection remains difficult because of the complex nature of student life and academic performance. Also, video game usage may simply be a function of specific personality types and characteristics.

  14. Searching for sources of variance in speech recognition: Young adults with normal hearing

    Watson, Charles S.; Kidd, Gary R.

    2005-04-01

    In the present investigation, sensory-perceptual abilities of one thousand young adults with normal hearing are being evaluated with a range of auditory, visual, and cognitive measures. Four auditory measures were derived from factor-analytic analyses of previous studies with 18-20 speech and non-speech variables [G. R. Kidd et al., J. Acoust. Soc. Am. 108, 2641 (2000)]. Two measures of visual acuity are obtained to determine whether variation in sensory skills tends to exist primarily within or across sensory modalities. A working memory test, grade point average, and Scholastic Aptitude Test scores (Verbal and Quantitative) are also included. Preliminary multivariate analyses support previous studies of individual differences in auditory abilities (e.g., A. M. Surprenant and C. S. Watson, J. Acoust. Soc. Am. 110, 2085-2095 (2001)] which found that spectral and temporal resolving power obtained with pure tones and more complex unfamiliar stimuli have little or no correlation with measures of speech recognition under difficult listening conditions. The current findings show that visual acuity, working memory, and intellectual measures are also very poor predictors of speech recognition ability, supporting the independence of this processing skill. Remarkable performance by some exceptional listeners will be described. [Work supported by the Office of Naval Research, Award No. N000140310644.

  15. No special K! A signal detection framework for the strategic regulation of memory accuracy.

    Higham, Philip A

    2007-02-01

    Two experiments investigated criterion setting and metacognitive processes underlying the strategic regulation of accuracy on the Scholastic Aptitude Test (SAT) using Type-2 signal detection theory (SDT). In Experiment 1, report bias was manipulated by penalizing participants either 0.25 (low incentive) or 4 (high incentive) points for each error. Best guesses to unanswered items were obtained so that Type-2 signal detection indices of discrimination and bias could be calculated. The same incentive manipulation was used in Experiment 2, only the test was computerized, confidence ratings were taken so that receiver operating characteristic (ROC) curves could be generated, and feedback was manipulated. The results of both experiments demonstrated that SDT provides a viable alternative to A. Koriat and M. Goldsmith's (1996c) framework of monitoring and control and reveals information about the regulation of accuracy that their framework does not. For example, ROC analysis indicated that the threshold model implied by formula scoring is inadequate. Instead, performance on the SAT should be modeled with an equal-variance Gaussian, Type-2 signal detection model. ((c) 2007 APA, all rights reserved).

    If SUSY provides a solution to the hierarchy problem then supersymmetric states should not be too heavy. This requirement is quantified by the Barbieri-Giudice fine tuning measure that provides a quantitative test of SUSY as a solution to the hierarchy problem. The measure is useful in correlating the impact of the various experimental measurements relevant to the search for supersymmetry and also in identifying the most sensitive measurements for testing SUSY. In this paper we apply the measure to the CMSSM, computing it to two-loop order and taking account of current experimental limits and the constraint on dark matter abundance. Using this we determine the present limits on the CMSSM parameter space and identify the measurements at the LHC that are most significant in covering the remaining parameter space. Without imposing the LEP Higgs mass bound we show that the smallest fine tuning (1:14.5) consistent with a saturation of the relic density within the 1$\\sigma$ WMAP bounds corresponds to a Higgs mass o...

    The current situation of oocyte donation in the USA serves as a useful paradigm for a laissez-faire free-market model of egg donor reimbursement, based on supply and demand. There is a rapidly emerging consensus of what would be considered desirable attributes in an egg donor, which would in turn determine her market value in financial reimbursement. First and foremost is the race and ethnicity of the donor. As expected, the shortage of egg donors from some ethnic groups such as East Asians and Jews has resulted in higher reimbursement rates for donors of such ethnicity. Second is the educational attainment of the donor, in particular high scholastic aptitude test scores and degrees from prestigious universities. Third is the employment status and career of the prospective donor. Last, but not least, are the personal esthetics of the egg donor, her physical appearance, from complexion to stature. These can be summarized as the Four Es: ethnicity, education, employment and esthetics, which are somewhat analogous to the Four Cs of diamond price valuation (colour, clarity, carat and cut). Although such an analogy may appear rather superficial, the free-market systems that have evolved in response to a growing demand for these two completely unrelated items are uncannily similar.

    Full Text Available There is concern that online education may widen the achievement gap between students from different socioeconomic classes. The recent discussion of integrating massive open online courses (MOOCs into formal higher education has added fuel to this debate. In this study, factors influencing enrollment and completion in a pre-college preparatory MOOC were explored. University of California at Irvine (UCI students of all preparation levels, defined by math Scholastic Aptitude Test (SAT score, were invited to take a Bio Prep MOOC to help them prepare for introductory biology. Students with math SAT below 550 were offered the explicit incentive of an early change to the biology major upon successful completion of the MOOC and two additional onsite courses. Our results demonstrate that, among course registrants, a higher percentage of UCI students (>60% completed the course than non-UCI registrants from the general population (<9%. Female UCI students had a greater likelihood of enrolling in the MOOC, but were not different from male students in terms of performance. University students entering with low preparation outperformed students entering who already had the credentials to become biology majors. These findings suggest that MOOCs can reach students, even those entering college with less preparation, before they enter university and have the potential to prepare them for challenging science, technology, engineering, and mathematics (STEM courses.

    The aim of this study was to identify the cognitive factors that predictability and adaptability during multitasking with a flight simulator. Multitasking has become increasingly prevalent as most professions require individuals to perform multiple tasks simultaneously. Considerable research has been undertaken to identify the characteristics of people (i.e., individual differences) that predict multitasking ability. Although working memory is a reliable predictor of general multitasking ability (i.e., performance in normal conditions), there is the question of whether different cognitive faculties are needed to rapidly respond to changing task demands (adaptability). Participants first completed a battery of cognitive individual differences tests followed by multitasking sessions with a flight simulator. After a baseline condition, difficulty of the flight simulator was incrementally increased via four experimental manipulations, and performance metrics were collected to assess multitasking ability and adaptability. Scholastic aptitude and working memory predicted general multitasking ability (i.e., performance at baseline difficulty), but spatial manipulation (in conjunction with working memory) was a major predictor of adaptability (performance in difficult conditions after accounting for baseline performance). Multitasking ability and adaptability may be overlapping but separate constructs that draw on overlapping (but not identical) sets of cognitive abilities. The results of this study are applicable to practitioners and researchers in human factors to assess multitasking performance in real-world contexts and with realistic task constraints. We also present a framework for conceptualizing multitasking adaptability on the basis of five adaptability profiles derived from performance on tasks with consistent versus increased difficulty.

    Undergraduates entering science curricula differ greatly in individual starting points and learning needs. The fast pace, high enrollment, and high stakes of introductory science courses, however, limit students' opportunities to self-assess and modify learning strategies. The University of Washington's Biology Fellows Program (BFP) intervenes through a 20-session, premajors course that introduces students to the rigor expected of bioscience majors and assists their development as science learners. This study uses quantitative and qualitative approaches to assess whether the 2007-2009 BFP achieved its desired short- and long-term impacts on student learning. Adjusting for differences in students' high school grade point average and Scholastic Aptitude Test scores, we found that participation in the BFP was associated with higher grades in two subsequent gateway biology courses, across multiple quarters and instructors. Two to 4 yr after participating in the program, students attributed changes in how they approached learning science to BFP participation. They reported having learned to "think like a scientist" and to value active-learning strategies and learning communities. In addition, they reported having developed a sense of belonging in bioscience communities. The achievement of long-term impacts for a short-term instructional investment suggests a practical means to prepare diverse students for the rigors of science curricula.

    Three independent lines of inquiry have found associations between alcohol use and academic performance, sleep and academic performance, and alcohol use and sleep. The present study bridges this research by examining the links among alcohol use, sleep, and academic performance in college students. Personal interview surveys were conducted with a random sample of 236 students (124 women) at a liberal arts college. The interviews measured alcohol consumption, gender, academic class, weekday and weekend bedtimes and rise times, and daytime sleepiness; 95% of the sample granted permission to obtain grade-point average (GPA) and Scholastic Aptitude Test (SAT) scores from official college records. Ordinary least squares regressions showed that alcohol consumption was a significant predictor of four sleep patterns: the duration of sleep, the timing of sleep, the difference between weekday and weekend nighttime sleep hours (oversleep), and the difference between weekday and weekend bedtimes (bedtime delay). Women and students with late sleep schedules were more apt to report daytime sleepiness. SAT score was the strongest predictor of GPA. However, gender, alcohol consumption, sleep duration, and daytime sleepiness also were significant predictors when other variables were controlled. In addition to alcohol's direct relationship with GPA, mediational analysis indicated that alcohol had indirect effects on sleepiness and GPA, primarily through its effect on sleep schedule. The findings show how alcohol use among college students is related to sleep-wake patterns and further support the connection between alcohol use and grades.

    While the construct of integrity has emerged as a front-runner amongst the desirable attributes to select for in medical school admissions, it is less clear how best to assess this characteristic. A potential solution lies in the use of Situational Judgement Tests (SJTs) which have gained popularity due to robust psychometric evidence and potential for large-scale administration. This study aims to explore the psychometric properties of an SJT designed to measure the construct of integrity. Ten SJT scenarios, each with five response stems were developed from critical incident interviews with academic and clinical staff. 200 of 520 (38.5 %) Multiple Mini Interview candidates at Dundee Medical School participated in the study during the 2012-2013 admissions cycle. Participants were asked to rate the appropriateness of each SJT response on a 4-point likert scale as well as complete the HEXACO personality inventory and a face validity questionnaire. Pearson's correlations and descriptive statistics were used to examine the associations between SJT score, HEXACO personality traits, pre-admissions measures namely academic and United Kingdom Clinical Aptitude Test (UKCAT) scores, as well as acceptability. Cronbach's alpha reliability for the SJT was .64. Statistically significant correlations ranging from .16 to .36 (.22 to .53 disattenuated) were observed between SJT score and the honesty-humility (integrity), conscientiousness, extraversion and agreeableness dimensions of the HEXACO inventory. A significant correlation of .32 (.47 disattenuated) was observed between SJT and MMI scores and no significant relationship with the UKCAT. Participant reactions to the SJTs were generally positive. Initial findings are encouraging regarding the psychometric robustness of an integrity-based SJT for medical student selection, with significant associations found between the SJTs, integrity, other desirable personality traits and the MMI. The SJTs showed little or no redundancy with

  18. Ethics, genetic testing, and athletic talent: children's best interests, and the right to an open (athletic) future.

    Camporesi, Silvia; McNamee, Mike J

    In this paper we discuss the ethics of genetics-based talent identification programs in sports. We discuss the validity and reliability of the tests and the claims made by direct to consumer companies, before presenting a range of ethical issues concerning child-parent/guardian relations raised by these tests, which we frame in terms of parental/guardian duties, children's rights, and best interests. We argue that greater ethical emphasis needs to be put on the parental decision on the wellbeing on the child going forward, not on ex post justifications on the basis of good and bad consequences. Best interests decisions made by a third party seem to comprise both subjective and objective elements, but only a holistic approach can do justice to these questions by addressing the wellbeing of the child in a temporal manner and taking into account the child's perspective on its wellbeing. Such decisions must address wider questions of what a good (sports)parent ought do to help the child flourish and how to balance the future-adult focus necessary to nurture talent with the wellbeing of the child in the present. We conclude that current genetic tests for "talent" do not predict aptitude or success to any significant degree and are therefore only marginally pertinent for talent identification. Claims that go beyond current science are culpable and attempt to exploit widespread but naïve perceptions of the efficacy of genetics information to predict athletic futures. Sports physicians and health care professionals involved in sport medicine should therefore discourage the use of these tests. Copyright © 2016 the American Physiological Society.

  19. Boys and girls who reason well mathematically.

    Since 1971 the Study of Mathematically Precocious Youth (SMPY) at Johns Hopkins University has pioneered in discovery of and provision of educational help for 12-year-old boys and girls who reason better mathematically than 99% of other 12-year-olds. SMPY originated widespread searches for such youths and special academic classes for them outside the regular school system. A regional talent search, verbal as well as mathematical, now covers all 50 states of the USA, and many varied residential summer programmes are offered across the country. These have provided educational facilitation for many thousands, and have encouraged greater curricular flexibility in schools and better articulation of in-school with out-of-school learning experiences. From the first talent search conducted by SMPY in 1972, it became obvious that boys tend to score considerably higher than girls on the College Board Scholastic Aptitude Test-Mathematical (SAT-M), a test intended mainly for college-bound 17- and 18-year-olds. This difference was reported in 1974 but attracted little attention until a controversial report in 1980 stimulated research on sex differences in various aspects of mathematics. Here I describe a study of sex differences over 10 years on 14 College Board high school achievement tests, which are taken (three usually) by bright 17- and 18-year-olds seeking admission to the USA's selective colleges and universities. Among the high scores on the European history test the ratio of males to females was greatest, 6:1. The next most sex-differentiating test was physics, 2.9:1, followed by elementary-level mathematics (mainly algebra and geometry), 2.5:1. Other ratios favouring males were, in 1991, chemistry (2.4:1), American history (2.1:1), biology (1.8:1), precalculus mathematics (1.6:1), Latin (1.6:1), French (1.4:1), modern Hebrew (1.1:1) and German (1.02:1). Tests in which more females were high scorers were literature (1.26:1), English composition (1.05:1) and Spanish (1
