    Lim, Hayoung A

    2011-01-01

    The purpose of the Music Therapy Career Aptitude Test (MTCAT) was to measure the affective domain of music therapy students including their self-awareness as it relates to the music therapy career, value in human development, interest in general therapy, and aptitude for being a professional music therapist. The MTCAT was administered to 113 music therapy students who are currently freshman or sophomores in an undergraduate music therapy program or in the first year of a music therapy master's equivalency program. The results of analysis indicated that the MTCAT is normally distributed and that all 20 questions are significantly correlated with the total test score of the MTCAT. The reliability of the MTCAT was considerably high (Cronbach's Coefficient Alpha=0.8). The criterion-related validity was examined by comparing the MTCAT scores of music therapy students with the scores of 43 professional music therapists. The correlation between the scores of students and professionals was found to be statistically significant. The results suggests that normal distribution, internal consistency, homogeneity of construct, item discrimination, correlation analysis, content validity, and criterion-related validity in the MTCAT may be helpful in predicting music therapy career aptitude and may aid in the career decision making process of college music therapy students.

  5. Aptitude for conference interpreting : one test or two?

    OpenAIRE

    Timarova, Sarka; Rejskova, Jana

    2009-01-01

    Literature on interpreting discusses two main modes of conference interpreting (consecutive and simultaneous), but aptitude for interpreting seems to be understood as a single construct. Accordingly, admission tests typically do not include separate tests for consecutive and simultaneous interpreting aptitude. Rejšková (1999) set out to explore this issue, and concluded that consecutive and simultaneous interpreting tap different skills and warrant separate aptitude tests. In the pres...

    Aponte, G.; Cadavid, H.; Castro, F.; Lozano, C. [Universidad del Valle, Cali (Colombia). Dept. de Fisica; Lurie, A.I. [All-Russian Electrotechnical Institute, Moscow, (Russian Federation)

    1997-12-31

    Methods to increase the quality of transformers in Colombia`s electric power distribution system were discussed. Considerable effort has been expended in ensuring the transformer`s aptitude to support the electrodynamic loads that are presented under short circuit conditions. This involves complex technical problems related to magnetic fields and calculations of electrodynamic forces. Due to the scarcity of experience in Colombia with transformer withstand aptitude (SCWA) analysis, it was necessary to build a SCWA test field. The project stages and test results from two years of operation were described. The comprehensive research project included theoretical and methodological developments, modelling, calculations and tests. 5 refs., 4 figs.

    Hirschler, Robert; Gay, Jennifer; Ferreira de Oliveira, Danielle

    2002-06-01

    253 visual observers, at the average level of between 'unselected' (inexperienced) and 'in-plant applicants' have been tested under controlled industrial conditions using the Ishihara or T.M.C. (Murakami) pseudoisochromatic plates, the Farnworth-Munsell 100 Hue Test (FM), the HVC Color Vision Skill Test (HVC) and the Japanese Color Aptitude Test (JCAT). There is only loose correlation between the FM and the HVC tests. The FM scores do not improve significantly by retesting, while the HVC scores can be improved through training, e.g. by using the JCAT. We found practically no correlation between the performance in visual pass/fail decisions and the FM or the HVC scores. Three different editions (3 copies from 1991, 3 from 1997 and two from 1998) of the HVC test were measured and analyzed. They showed good, in the latest edition very good, intra-edition repeatability and good inter-edition reproducibility.

  8. Individual differences in left parietal white matter predict math scores on the Preliminary Scholastic Aptitude Test.

    Matejko, Anna A; Price, Gavin R; Mazzocco, Michèle M M; Ansari, Daniel

    2013-02-01

    Mathematical skills are of critical importance, both academically and in everyday life. Neuroimaging research has primarily focused on the relationship between mathematical skills and functional brain activity. Comparatively few studies have examined which white matter regions support mathematical abilities. The current study uses diffusion tensor imaging (DTI) to test whether individual differences in white matter predict performance on the math subtest of the Preliminary Scholastic Aptitude Test (PSAT). Grades 10 and 11 PSAT scores were obtained from 30 young adults (ages 17-18) with wide-ranging math achievement levels. Tract based spatial statistics was used to examine the correlation between PSAT math scores, fractional anisotropy (FA), radial diffusivity (RD) and axial diffusivity (AD). FA in left parietal white matter was positively correlated with math PSAT scores (specifically in the left superior longitudinal fasciculus, left superior corona radiata, and left corticospinal tract) after controlling for chronological age and same grade PSAT critical reading scores. Furthermore, RD, but not AD, was correlated with PSAT math scores in these white matter microstructures. The negative correlation with RD further suggests that participants with higher PSAT math scores have greater white matter integrity in this region. Individual differences in FA and RD may reflect variability in experience dependent plasticity over the course of learning and development. These results are the first to demonstrate that individual differences in white matter are associated with mathematical abilities on a nationally administered scholastic aptitude measure.

    Advocates of using a US-style SAT for university selection claim that it is fairer to applicants from disadvantaged backgrounds than achievement tests because it assesses potential, not achievement, and that it allows finer discrimination between top applicants than GCEs. The pros and cons of aptitude tests in principle are discussed, focusing on…

  12. [Predicting the success of occupational retraining using the occupational aptitude test battery].

    Science.gov (United States)

    Kreuzpointner, L

    2009-04-01

    In vocational retraining centres, a test battery including several performance tests is generally administered to assess the occupational aptitude of rehabilitants and to predict their success in occupational retraining. This paper presents the multiple regressions of a set of achievement scores on "grades of retraining" and "grades of final examination", respectively, concerning retraining to become an office management assistant. It was shown that only few variables are adequate to clarify a maximum of variance of the criterions. Four different regression models were identified; each of them could clarify about 25% of variance. Significant predictors were indicators for verbal skills and basic numeracy. In each model a measurement for nonverbal intelligence had to be taken into account as a suppressor variable. To put all in a nutshell, in order to predict the success of vocational retraining to become an office management assistant it is more important to focus on strengthening school knowledge than on general intelligence.

    2012-01-01

    The German Aptitude Test for Medical Studies (TMS) was implemented in 2007. 12,194 persons registered for this test in 2011, which represents a 91% increase over 2007. The male/female ratio remained constant at 38:62. Its reliability among applicants to Heidelberg Medical Faculty was confirmed by Cronbach's α (≥ 0.75) and inter-item correlation (≥ 0.25, p < 10(-7)). The TMS contains nine items; using factor analysis these were allocated to the two components verbal-mathematical and spatial-figural ability. The verbal-mathematical items moderately correlate with the German Baccalaureate GPA (r = 0.33), while the spatial-figural items do not correlate (r = 0.07). Thus, the TMS is an admission instrument that appraise different cognitive abilities than the GPA. For the admission of students to our faculty their TMS scores are weighted at 39%, which has resulted in a diversification of our student cohorts. PMID:22480896

  3. 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.

  14. Aptitude test and classification of materials with class width of statistically evaluated distinction

    International Nuclear Information System (INIS)

    Classification into classes of statistically evaluated distinction is an appropriate means of assigning various materials properties simply and quickly into the relevant groups of being equivalent or different. This information, however, is subject to statistical uncertainties due to the relatively small number of samples used for materials properties testing; the large variety of materials properties modify the information on possible differences. One factor to be taken into account in determining the class width is a sufficient probability by which a difference between two materials properties can be stated when the average sample data are differing by one or more class widths. For this case, formulas for determining the required class widths, derived by a test well-known in statistical mathematics, are presented in this paper and described by numerical examples.

    Abstract The 2-hour long United Kingdom Clinical Aptitude Test (UKCAT) is used by many universities in the United Kingdom as part of their selection process for undergraduate medical and dentistry degrees. We aimed to compare the performance of senior doctors in primary and secondary care and across a range of specialties, in a modified version of the medical school entrance examination—the mUKCAT. Lay people were also included in the study. Despite its widespread use, this is the first study that examines the performance of senior clinicians in the UKCAT. The study used a prospective cross-sectional design. It used mock questions from the UKCAT website to generate an mUKCAT that was anticipated to take 15 minutes to complete. In all, 167 doctors at consultant, general practitioner (GP), or specialty trainee grade and 26 lay people took part. The overall mean mUKCAT score of all participants was 2486 (69.1%). Of the total cohort, 126 (65.3%) scored above our designated threshold of 2368 and were deemed to have passed the mUKCAT. Excluding lay people, 113 (67.7%) of the 167 doctors scored above that threshold. Medical specialty was associated with overall score (P = 0.003), with anesthetists/intensive care physicians scoring highest (n = 20, mean score 2660) and GPs scoring lowest (n = 38, mean score 2302). Academics outperformed nonacademics (mean score of academics, n = 44 vs nonacademics, n = 123: 2750 vs 2406; P < 0.001). Those clinicians in senior management positions scored lower than those in “standard” roles (mean score of senior management, n = 31 vs standard roles, n = 136: 2332 vs 2534, mean difference 202, 95% confidence interval 67–337, P = 0.004). In the situational judgement section, there was no evidence that specialty was associated with score (P = 0.15). Academics exhibited greater situational judgement than their nonacademic colleagues (academics vs nonacademics: 69.8 vs 63.6%; P = 0.01). The

    2010-07-01

    Full Text Available Abstract Background The UK Clinical Aptitude Test (UKCAT was introduced in 2006 as an additional tool for the selection of medical students. It tests mental ability in four distinct domains (Quantitative Reasoning, Verbal Reasoning, Abstract Reasoning, and Decision Analysis, and the results are available to students and admissions panels in advance of the selection process. As yet the predictive validity of the test against course performance is largely unknown. The study objective was to determine whether UKCAT scores predict performance during the first two years of the 5-year undergraduate medical course at Nottingham. Methods We studied a single cohort of students, who entered Nottingham Medical School in October 2007 and had taken the UKCAT. We used linear regression analysis to identify independent predictors of marks for different parts of the 2-year preclinical course. Results Data were available for 204/260 (78% of the entry cohort. The UKCAT total score had little predictive value. Quantitative Reasoning was a significant independent predictor of course marks in Theme A ('The Cell', (p = 0.005, and Verbal Reasoning predicted Theme C ('The Community' (p Conclusion This limited study from a single entry cohort at one medical school suggests that the predictive value of the UKCAT, particularly the total score, is low. Section scores may predict success in specific types of course assessment. The ultimate test of validity will not be available for some years, when current cohorts of students graduate. However, if this test of mental ability does not predict preclinical performance, it is arguably less likely to predict the outcome in the clinical years. Further research from medical schools with different types of curriculum and assessment is needed, with longitudinal studies throughout the course.

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. PMID:19138441

    American psychologist Carroll (1981) defined language aptitude as an individual ability of learning a task when the learner is motivated and has the opportunity of doing so. The teacher can motivate all learners if the lesson is adjusted to every learner’s abilities. In the 50ies Carroll and Sapon developed the first language aptitude test for learning modern languages (MLAT – Modern Language Aptitude Test) which was used for identifying language learners who learn additional languages faster...

    2016-05-01

    The 2-hour long United Kingdom Clinical Aptitude Test (UKCAT) is used by many universities in the United Kingdom as part of their selection process for undergraduate medical and dentistry degrees. We aimed to compare the performance of senior doctors in primary and secondary care and across a range of specialties, in a modified version of the medical school entrance examination-the mUKCAT. Lay people were also included in the study. Despite its widespread use, this is the first study that examines the performance of senior clinicians in the UKCAT.The study used a prospective cross-sectional design. It used mock questions from the UKCAT website to generate an mUKCAT that was anticipated to take 15 minutes to complete. In all, 167 doctors at consultant, general practitioner (GP), or specialty trainee grade and 26 lay people took part.The overall mean mUKCAT score of all participants was 2486 (69.1%). Of the total cohort, 126 (65.3%) scored above our designated threshold of 2368 and were deemed to have passed the mUKCAT. Excluding lay people, 113 (67.7%) of the 167 doctors scored above that threshold. Medical specialty was associated with overall score (P = 0.003), with anesthetists/intensive care physicians scoring highest (n = 20, mean score 2660) and GPs scoring lowest (n = 38, mean score 2302). Academics outperformed nonacademics (mean score of academics, n = 44 vs nonacademics, n = 123: 2750 vs 2406; P < 0.001). Those clinicians in senior management positions scored lower than those in "standard" roles (mean score of senior management, n = 31 vs standard roles, n = 136: 2332 vs 2534, mean difference 202, 95% confidence interval 67-337, P = 0.004).In the situational judgement section, there was no evidence that specialty was associated with score (P = 0.15). Academics exhibited greater situational judgement than their nonacademic colleagues (academics vs nonacademics: 69.8 vs 63.6%; P = 0.01).The majority of senior

    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.

  11. Academic Performance of Students with the Highest and Mediocre School-leaving Grades: Does the Aptitude Test for Medical Studies (TMS Balance Their Prognoses?

    Directory of Open Access Journals (Sweden)

    Kadmon, Guni

    2016-02-01

    Full Text Available Background: Admission to undergraduate medical training in Germany occurs by central and local pathways. Central admission includes two distinct groups: Students with top school-leaving grades (best-SLG group and students with inferior school-leaving grades who are admitted with a delay of up to seven years (delayed admission group. Students with academic difficulties and early dropouts are present in both groups. Local admission at our university involves the German Test for Medical Studies (TMS and allows the admission by merit of students with a wide range of school-leaving grades. Aims: To examine the justification of a TMS-based strategy to reduce the admission of potentially weak best school-leavers and enhance the admission of potentially able candidates with mediocre school-leaving grades.Method: The prognostic contribution of the school-leaving (SL GPA and the TMS to academic performance and to continuity in the pre-clinical part of the undergraduate medical program was examined in two study groups: best school leavers (SL grade 1.0, SL-GPA 823-900 points and mediocre school leavers (SL grades 2.0-2.3, SL-GPA 689-660 points. The outcomes in both groups were compared in relation to their TMS results. The prospective study included four consecutive cohorts. Results: In each study group the TMS predicted the academic performance (β=0.442-0.446 and the continuity of studies (OR=0.890-0.853 better than the SL-GPA (β=0.238-0.047; OR=1.009-0.998. Attrition was most strongly associated with failing to take the TMS (OR=0.230-0.380. Mediocre school leavers with TMS scores ≥125 performed as well as the best school leavers. Mediocre school leavers with TMS scores between 110-124 performed on average less well but within the required standards. Best school leavers with mediocre TMS scores and 30% of the best school leavers who hadn't taken the TMS performed less well than most mediocre school leavers with high TMS scores. Discussion: The TMS

    The study of individual differences encompasses broad constructs including intelligence, creativity, and personality. However, substantially less research is devoted to the study of specific aptitudes in spite of their importance to educational, occupational, and avocational success. We sought to determine subcortical brain structural correlates of several broad aptitudes including Math, Vocabulary, Foresight, Paper Folding, and Inductive Reasoning in a large (N = 107), healthy, young (age range  = 16-29) cohort. Subcortical volumes were measured using an automated technique (FreeSurfer) across structures including bilateral caudate, putamen, globus pallidus, thalamus, nucleus accumbens, hippocampus, amygdala, and five equal regions of the corpus callosum. We found that performance on measures of each aptitude was predicted by different subcortical structures: Math--higher right nucleus accumbens volume; Vocabulary--higher left hippocampus volume; Paper Folding--higher right thalamus volume; Foresight--lower right thalamus and higher mid anterior corpus callosum volume; Inductive Reasoning--higher mid anterior corpus callosum volume. Our results support general findings, within the cognitive neurosciences, showing lateralization of structure-function relationships, as well as more specific relationships between individual structures (e.g., left hippocampus) and functions relevant to particular aptitudes (e.g., Vocabulary).

    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 (h(2) = .84; composing h(2) = .40; arranging h(2) = .46; improvising h(2) = .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

  1. Lack of research aptitude in medical education

    Directory of Open Access Journals (Sweden)

    2014-02-01

    Full Text Available Students are attracted towards the medical profession to become a doctor and not to be a researcher. According to a recent study there are about 1,00,000 undergraduate medical students in India at a given point of time, out of them only 0.9% of the students have shown research aptitude. During their training period of graduation in medical sciences, they are so much burdened with the work load of exams, practicals, ward duties and tutorials. In such an over burdened situation very few of them can think about research. A study had shown that training in research methodology received early in medical school helps students to develop a positive attitude towards research. So changes in the undergraduate and postgraduate curriculum are required to promote research among medical students. [Int J Basic Clin Pharmacol 2014; 3(1.000: 247-248

    Magne, Cyrille; Jordan, Deanna K; Gordon, Reyna L

    2016-02-01

    This study investigated the electrophysiological markers of rhythmic expectancy during speech perception. In addition, given the large literature showing overlaps between cognitive and neural resources recruited for language and music, we considered a relation between musical aptitude and individual differences in speech rhythm sensitivity. Twenty adults were administered a standardized assessment of musical aptitude, and EEG was recorded as participants listened to sequences of four bisyllabic words for which the stress pattern of the final word either matched or mismatched the stress pattern of the preceding words. Words with unexpected stress patterns elicited an increased fronto-central mid-latency negativity. In addition, rhythm aptitude significantly correlated with the size of the negative effect elicited by unexpected iambic words, the least common type of stress pattern in English. The present results suggest shared neurocognitive resources for speech rhythm and musical rhythm. PMID:26828758

    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. The results are commented on in the discussion. Relevant teaching implications are included in the conclusion.

  11. Enhancing the visuo-spatial aptitude of students

    Science.gov (United States)

    Lord, Thomas R.

    Research to date has not been able to agree whether visuo-spatial ability can be influenced through practice. Many have concluded that spatial awareness is an innate phenomena and cannot be learned. Others contend that an individual's visuo-spatial potentials are acquired through interactions with the environment. Many of these theorists believe that spatial thinking can be developed through interactive exercises devised to encourage mental image formation and manipulation. To help alleviate the confusion surrounding this question the following study was undertaken. Eighty-four college undergraduates were randomly placed into control and experimental sections. Student records were examined to assure that the groups did not differ significantly in their verbal or math proficiency and pertinent pretests were given to ascertain spatial levels. The groups were also similar on their male and female ratios. During the semester the experimental section was treated to a 30-minute interaction each week. These sessions involved spatial exercises that required the participants to mentally bisect three-dimensional geometric figures and to envision the shape of the two-dimensional surface formed by the bisection. The subjects drew their mental image of this surface on a sheet of paper. Fourteen weeks later both groups were post tested with a second comparable version of the pretest. Statistical t tests were performed on the group means to see if significant differences developed between the sections. The results indicate that statistical improvement in visuo-spatial cognition did occur for the experimental group in spatial visualization, and spatial orientation. This finding suggests that the weekly intervention sessions had a positive effect on the students' visuo-spatial awareness. These results, therefore, tend to support those researchers that claim visuo-spatial aptitude can be enhanced through teaching.

    Full Text Available [english] Introduction: The present study examines the question whether the selection of dental students should be based solely on average school-leaving grades (GPA or whether it could be improved by using a subject-specific aptitude test.Methods: The HAM-Nat Natural Sciences Test was piloted with freshmen during their first study week in 2006 and 2007. 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. Methoden: Der Naturwissenschaftstest HAM-Nat wurde in den Jahren 2006 und 2007 in der Erstsemesterwoche an den Studienanfängerinnen und -anfängern* erprobt sowie 2009 und 2010 im Auswahlverfahren eingesetzt. Die Stichprobengrößen der Regressionsmodelle variieren in allen Jahrgängen zwischen 32 und 55 Teilnehmern. Ergebnisse: Der HAM-Nat erklärte zusätzlich zur Abiturdurchschnittsnote bis zu 12 % der Leistungsvarianz in den vorklinischen Prüfungsleistungen. Die in anderen Studien gefundene prognostische Güte der Abiturdurchschnittsnote konnte für einige, aber nicht für alle Einzelprüfungen bestätigt werden. Schlussfolgerung: Der HAM-Nat erwies sich als zuverlässiges Auswahlinstrument

    Full Text Available La valoración de la aptitud forma parte de la actividad diaria del médico del trabajo. La queja generalizada es que no hay criterios estandarizados para ello. 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. Las patologías hasta ahora más estudiadas son la hipertensión arterial y las deficiencias en la agudeza visual. Los profesionales en los cuales se vigila más las capacidades psicofísicas son los conductores y los pilotos de aviación.The assessment of aptitude is part of the daily activity of occupational health doctors.

    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. PMID:26356378

  16. Directed-inquiry approach to learning science process skills: treatment effects and aptitude-treatment interactions

    Science.gov (United States)

    Germann, Paul J.

    The directed-inquiry approach to learning science process skills and scientific problem solving [DIAL(SPS)2] was developed to help high-school students gain the critical thinking skills required to solve problems in the biology lab. This curriculum integrated several learning strategies into a single approach: advance organizers, the learning cycle, concept maps, Vee diagrams, a focusing strategy, and writing. Two general questions were addressed. First, was the DIAL(SPS)2 treatment more effective than a conventional treatment? Second, was there evidence of an aptitude-treatment interaction? Four high-school biology classes taught by this investigator were used to test the DIAL(SPS)2 curriculum. Scheduling of students involved ability grouping. To test the curriculum in the most rigorous way, the experimental group consisted of average ability students and the comparison group consisted of above-average students. Both the groups were pretested in August and posttested in May. In the intervening time, the experimental group received the DIAL(SPS)2 treatment while the comparison group received a more traditional approach. Analysis of covariance revealed that the DIAL(SPS)2 curriculum had no significant effect on the learning of science process skills or on cognitive development. Aptitude-treatment interaction analyses revealed an interaction of DIAL(SPS)2 treatment and cognitive development.

    Cognitive performance on An Inventory of Piaget's Developmental Tasks (IPDT) was related to the Scholastic Aptitude Tests and performance in both college chemistry lecture and laboratory classes. The IPDT is a valid and reliable 72-item, untimed, multiple-choice paper-and-pencil inventory. It has 18 subtests grouped into five problem areas representing different Piagetian tasks. Subjects (n = 225) from two different levels of introductory chemistry courses participated. IPDT scores were significantly correlated with SAT and placement data. In overall Piagetian development, A students rated higher than others. Performance in classification and proportional reasoning problem areas correlated with course achievement, particularly for higher-level students. Weakest areas of development were indicated by subtest scores and are described with implications for course performance. Finally, Piagetian tasks were related to learning and instructional activities in introductory chemistry classes and are discussed.

In our analysis, we plot exam scores versus homework completion scores and calculate the slopes of the line fits and the Pearson correlations. On average, completing many homework problems correlated to better exam scores only for students with high physics aptitude. Low aptitude physics students had a negative correlation between exam performance and completing homework; the more homework problems they did, the worse their performance was on exams. One explanation for this effect is that the assigned homework problems placed an excessive cognitive load on low aptitude students. As a result, no learning or even negative learning might have taken place when low aptitude students attempted to do assigned homework. Another explanation is based on the fact that the negative benefit effects first appeared when ...

    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. PMID:24195252

    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.

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

    Directory of Open Access Journals (Sweden)

    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.

    We examine how student aptitudes impact how much students learn from doing graded online and written homework in an introductory electricity and magnetism course. 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.

    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. PMID:24392451

  1. Verbal aptitude and the use of grammar information in Serbian language

    2006-01-01

    Full Text Available The research presented in this paper was an attempt to find differences in the use of grammatical information carried by the function words in Serbian. 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. .

    Abilities related to musical aptitude appear to have a long history in human evolution. To elucidate the molecular and evolutionary background of musical aptitude, we compared genome-wide genotyping data (641 K SNPs) of 148 Finnish individuals characterized for musical aptitude. We assigned signatures of positive selection in a case-control setting using three selection methods: haploPS, XP-EHH and FST. Gene ontology classification revealed that the positive selection regions contained genes affecting inner-ear development. Additionally, literature survey has shown that several of the identified genes were known to be involved in auditory perception (e.g. GPR98, USH2A), cognition and memory (e.g. GRIN2B, IL1A, IL1B, RAPGEF5), reward mechanisms (RGS9), and song perception and production of songbirds (e.g. FOXP1, RGS9, GPR98, GRIN2B). Interestingly, genes related to inner-ear development and cognition were also detected in a previous genome-wide association study of musical aptitude. However, the candidate genes detected in this study were not reported earlier in studies of musical abilities. Identification of genes related to language development (FOXP1 and VLDLR) support the popular hypothesis that music and language share a common genetic and evolutionary background. The findings are consistent with the evolutionary conservation of genes related to auditory processes in other species and provide first empirical evidence for signatures of positive selection for abilities that contribute to musical aptitude.

  4. 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.

  9. Prediction of auditory and visual p300 brain-computer interface aptitude.

    Directory of Open Access Journals (Sweden)

    Sebastian Halder

    Full Text Available OBJECTIVE: Brain-computer interfaces (BCIs provide a non-muscular communication channel for patients with late-stage motoneuron disease (e.g., amyotrophic lateral sclerosis (ALS or otherwise motor impaired people and are also used for motor rehabilitation in chronic stroke. Differences in the ability to use a BCI vary from person to person and from session to session. A reliable predictor of aptitude would allow for the selection of suitable BCI paradigms. For this reason, we investigated whether P300 BCI aptitude could be predicted from a short experiment with a standard auditory oddball. METHODS: Forty healthy participants performed an electroencephalography (EEG based visual and auditory P300-BCI spelling task in a single session. In addition, prior to each session an auditory oddball was presented. Features extracted from the auditory oddball were analyzed with respect to predictive power for BCI aptitude. RESULTS: Correlation between auditory oddball response and P300 BCI accuracy revealed a strong relationship between accuracy and N2 amplitude and the amplitude of a late ERP component between 400 and 600 ms. Interestingly, the P3 amplitude of the auditory oddball response was not correlated with accuracy. CONCLUSIONS: Event-related potentials recorded during a standard auditory oddball session moderately predict aptitude in an audiory and highly in a visual P300 BCI. The predictor will allow for faster paradigm selection. SIGNIFICANCE: Our method will reduce strain on patients because unsuccessful training may be avoided, provided the results can be generalized to the patient population.

  6. Aptitude treatment effects of laboratory grouping method for students of differing reasoning ability

    Science.gov (United States)

    Lawrenz, Frances; Munch, Theodore W.

    This study examines aptitude treatment effects in an inquiry/learning cycle based physical science class for elementary education majors. The aptitude was formal reasoning ability and the students were arranged into three groups: high, middle, and low ability reasoners. The treatment was method of forming groups to work in the laboratory. Students in each of three classes were grouped according to reasoning ability. In one class the laboratory groups were homogeneous, i.e., students of similar reasoning ability were grouped together. In the second class the students were grouped heterogeneously, i.e., students of different reasoning ability were grouped together. In the third class, the student choice pattern, the students chose their own partners. The findings were that there were no aptitude treatment interaction for achievement or for gain in formal reasoning ability, that grouping students of similar cognitive ability together for laboratory work in the class was more effective in terms of science achievement than grouping students of differing cognitive ability together or than allowing students to choose their own partners, and that students at different levels of reasoning ability experienced differential gains in that ability over the semester.

    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 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.

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

    2011-10-01

    Full Text Available Abstract 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

    Road safety is for several years a major public health issue, given the number of casualties and annual deaths caused by road accidents in France or Europe. European directives of 2006 and 2009 were aimed harmonized community practices for the conduct, including medically. We studied the laws in force in each of the 28 countries of the European Union to make an inventory of the organization on this subject. The results showed that 25 countries introduce, at least once, including 21 medical check regularly. Age is the main factor that motivates control. The frequency of examinations increases with the age of the driver. In other countries, a sworn statement of the absence of pathology is enough. Although a medical examination is mostly carried out systematically, it the content is extremely variable, ranging from a simple vision test to a full review with psycho test. Management of professional secrecy is approached differently in different countries, although predominantly an exemption exists in the event of discovery of the inability of a patient. We note that there is a great diversity in the medical screening modalities unsuited to driving. These systems will be harmonized to comply with the wishes of European directives. PMID:25960438

    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 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.

  15. Differential effects of verbal aptitude and study questions on comprehension of science concepts

    Holliday, William G.; Whittaker, Harold G.; Loose, Kenneth D.

    Selective attention models predict that verbatim study questions can divert students from meaningfully encoding attributes of science concepts. The aptitude-treatment interaction (ATI) hypothesis predicts that such questions can be particularly dysfunctional to low-ability students. These predictions assume the measurement of true comprehension of concepts as a criterion. Eighth-grade students (n = 217) were randomly assigned to a text-only, text-question or a placebo treatment. The text verbally described five fossil types. The questions consisted of 28 fill-in-the-blank queries about the text. The posttest required students to visually identify and discriminate 40 fossil specimens as to fossil type. Comprehension of the concepts clearly took place-a fact substantiated by the very low scores obtained by the placebo group. As predicted (p effected by the verbatim study questions. Main effects among these groups were also detected. Apparently such questions can overprompt students, resulting in their copying of words from a text to an answer-blank without semantically encoding (i.e., comprehending) the copied words.

    Difficulties with interpersonal relationships have been reported in children and adolescents with manic symptoms, even if they do not fulfil criteria for a manic episode. The role of social aptitude (SA) in youths with manic symptoms has never been examined in the general population. Moreover, no study has examined whether SA is differentially associated with dimensions of manic symptoms. We hypothesised that youth with predominantly undercontrol manic symptoms (characterised by irritability) would show lower levels of SA; conversely, youth with predominantly exuberant symptoms would show better than average social skills. Our sample comprised 5325 participants from the 2004 British Child and Adolescent Mental Health Survey (B-CAMHS04), mean age 10.3 years, SD = 3.3, 48 % girls. Manic symptoms were assessed with the Development and Wellbeing Assessment by interviewing parents and young people. Children and adolescents with manic symptoms had a lower SA score, compared to the general population by parent report, but not by self-report. SA score was higher in youths with predominantly exuberant manic symptoms compared to the general population; whereas the youths with predominantly undercontrol manic symptoms had lower SA scores by parent and self-report. Our results provide further evidence for the distinction between exuberant and undercontrol manic symptoms and highlight the need to focus on SA in future research. PMID:26650482

These variables were investigated across varying levels of academic aptitude. Two week long units were taught by 30 experienced science teachers. During this period of time teacher classroom management behavior, student achievement (n = 570), student engagement (n = 269), and student academic aptitude (n = 649) were measured. Twelve selected management indicators from Georgia Teachers Performance Assessment Indicators (TPAI) were used to measure teacher classroom management behaviors. Regression analysis was used to determine the relationship between the variables, and appropriate post hoc procedures were used. Analyses showed that there was a significant relationship among all variables. Post hoc analysis showed that these results were consistent across levels of aptitude. Other relationships found were between student engagement and achievement, student aptitude and achievement, and student aptitude and engagement. Correlation coefficients were obtained for each individual management indicators. Those particular management behaviors which were correlated with achievement and engagement are: identifies students who do not understand directions and helps them individually, maintains learner involvement in lessons, reinforces and encourages the efforts of learners to maintain involvement, attends to routine tasks, uses instructional time efficiently, provides feedback to learners about their behavior, manages disruptive behavior among learners.

    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'.

The winter lactation shows higher percentages of casein, lactose and not fat dry matter (P≤0.01; curd firming time (k20 is significantly lower and there is a greater curd firmness (a30 (P≤0.01; while in the summer there is a higher percentage of lipids (P≤0.01. The effect of the season significantly influences (P≤0.01 the size of the fat globules and impacted significantly on the fatty acids composition of the milk. In the hills the milk has a higher percentage of dry matter, protein, casein, fat, phosphorous and not fat dry matter (P≤0.01, whereas it has a lower percentage of lactose and calcium (P≤0.05. The Somatic Cell Count (SCC and the Total Bacterial Count (TBC are statistically greater on the plains (P≤0.01, while milk produced in the hills shows higher quantity of α-linolenic acid and lower saturated fatty acids (P≤0.05. In the two typical rearing areas for Massese ewes we found differences amongst dry matter, fat, phosphorous and SCC, higher (P≤0.01 in the province of Massa Carrara that also had the best rheological parameters, but we found the highest cheese yield (P≤0.05 in the province of Lucca where there are also the greatest weight loss (P≤0.01. The milks produced in the winter season and in hilly areas present the best physico-chemical and nutritional characteristics. However, we found that the technological side should be improved by diversifying cheese-making techniques in relation to the characteristics of milk. In fact, currently these techniques do not fully exploit the potential to transform those milks with the best qualitative

  1. Development of the Human Error Management Criteria and the Job Aptitude Evaluation Criteria for Rail Safety Personnel

    International Nuclear Information System (INIS)

    It has been estimated that up to 90% of all workplace accidents have human error as a cause. Human error has been widely recognized as a key factor in almost all the highly publicized accidents, including Daegu subway fire of February 18, 2003 killed 198 people and injured 147. Because most human behavior is 'unintentional', carried out automatically, root causes of human error should be carefully investigated and regulated by a legal authority. The final goal of this study is to set up some regulatory guidance that are supposed to be used by the korean rail organizations related to safety managements and the contents are : - to develop the regulatory guidance for managing human error, - to develop the regulatory guidance for managing qualifications of rail drivers - to develop the regulatory guidance for evaluating the aptitude of the safety-related personnel

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.

    It has long been held that people who have musical training or talent acquire L2 pronunciation more successfully than those that do not. Indeed, there have been empirical studies to support this hypothesis (Pastuszek-Lipińska 2003, Fonseca-Mora et al. 2011, Zatorre and Baum 2012). However, in many of such studies, musical abilities in subjects were mostly verified through questionnaires rather than tested in a reliable, empirical manner.

    Grapperon, J; Delage, M

    1999-01-01

    Utilization of the Stroop test with schizophrenic subjects is reviewed from 32 studies published since 1960. This test, in which subject has to name the color of color-words which are congruent or incongruent, is much used as a selective attention test. Its specific disturbance in schizophrenics would confirm the overload of consciousness with unsignificant non filtered information, probably due to lowering of frontal functions. Stroop effect is not always raised in these patients, especially when general slowing is taken into account. Technical differences modify the test power and can explain contradictory results. The thought disorder symptom seems the most correlated with the results of the test, and particular sensitiveness of paranoïd form has been argued. Neuroleptics do not seem to act on Stroop effect. Factors explaining the great variability of patients in this test are not fully put in light. One hypothesis, already raised, is that the test is linked to a particular attentional constitutional aptitude, and whose relations with the illness are to be explained. PMID:10205734

  10. Apocynin: Molecular Aptitudes

    Directory of Open Access Journals (Sweden)

    J. Stefanska

    2008-01-01

    Full Text Available Apocynin is a naturally occurring methoxy-substituted catechol, experimentally used as an inhibitor of NADPH-oxidase. It can decrease the production of superoxide (O2− from activated neutrophils and macrophages while the ability of phagocytosis remains unaffected. The anti-inflammatory activity of apocynin has been demonstrated in a variety of cell and animal models of inflammation. Apocynin, after metabolic conversion, inhibits the assembly of NADPH-oxidase that is responsible for reactive oxygen species (ROS production. It is, therefore, extensively used to reveal the role of this enzyme in cell and experimental models. Although some of the ROS serve as signaling molecules in the cells, excessive production is damaging and has been implicated to play an important role in the progression of many disease processes. This is why in many studies apocynin presents a promising potential treatment for some disorders; however, its utility with inflammatory diseases remains to be determined. Since its mode of action is not well defined, we tried to get a more precise insight into the mechanisms by which apocynin exerts its activity. Considering the anti-inflammatory activities of apocynin, we may conclude that this compound definitely deserves further study.

  5. Qualification tests for shift personnel in nuclear power plants

    International Nuclear Information System (INIS)

    The selection of personnel for training as shift supervisors or reactor operators so far used to be made by a plant operator mainly on the basis of such criteria as examinations, diplomas and other documents verifying the educational background, the type of activity exercised, and professional success. In addition, there are the opininons of trainers and supervisors based on personal observation of future shift personnel on training for specific plants at a training center, at the manufacturer's, the operator's or in activities in the construction and commissioning of the respective nuclear power plant. In the course of this phase, which normally takes several years, supervisors asses not only the professional capabilities of a trainee, but also bis psychic and physical performance and aptitude, e.g., with respect to decision making, leadership qualifications or behavior unter stress. The advisability of introducing psychological aptitude tests was also studied. However, a decision was recently taken to defer such psychological tests for the time being. Yet, nuclear power plant operators are required to submit a statement to their responsible authorities about industrial medical checkups and qualification assessments by supervisors. (orig.)

    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 excellence

    Robert J. Sternberg

    2015-12-01

    Full Text Available Standard conventional tests only assess a narrow sampling of the abilities required for success in school and in life. In contrast, the augmented theory of successful intelligence asserts that intelligence involves creative skills in producing new ideas, analytical skills in evaluating whether the ideas are good ones, practical skills in putting the ideas into practice and in convincing other people of the value of the ideas, and wisdom-based skills in confirming that one is using one's knowledge and skills to serve a common good. Three projects were created to evaluate the theory with regard to college admissions: First, the Rainbow Project demonstrated that prediction of first-year college academic performance could be increased while simultaneously decreasing differences between ethnic groups on a predictive assessment, in comparison with the Scholastic Aptitude Test (SAT. Second, the Kaleidoscope Project improved prediction of academic and extracurricular performance over SAT scores alone; but the ethnic-group differences usually obtained vanished. Third, the Panorama Project showed the success of similar techniques in a less selective population. The projects demonstrate the application of the augmented theory of successful intelligence in enhancing college and university admissions procedures

Esos tres conceptos, por otra parte, son especificaciones de tres conceptos de aplicación más universal. El concepto de función biológica es un caso particular del concepto general de función; y el concepto de aptitud especifica el concepto de conveniencia. El concepto de adaptación, mientras tanto, es una especificación del concepto de diseño.

    The ballet teaching is a part of the dance teaching, it has been more popular because the public aesthetic cognition, also because it is very difficult to have a sustained interest in many disciplines in the most difficult dance. Ballet training to require students to pay more tears and sweat, and has excellent physical conditions (i.e., three long and one small). Based on the characteristics of ballet teaching, teachers should ensure that students have lasting enthusiasm as the basic point, the balance of conflict in teaching. This requires teachers with high professional skills, rich expressive force, all-round development of teaching ability and communication affinity. But what is more important is that teachers should understand the differences of different students, to teach students in accordance with their aptitude. In order to ensure that they are to grow into healthy, stable, happy dancer and future educators.%芭蕾舞教学属舞蹈教学的一部分,它既因为符合大众审美认知受到更多人的喜爱,也因为是众多舞蹈学科中最艰辛的很难具有持续性的兴趣。芭蕾舞训练需要学生付出更多的泪水与汗水,并具有优异的身体条件(即三长一小)。基于芭蕾舞教学的特点,教师应该以保证学生具有长久的热情为基本点,平衡教学中的各项矛盾。这便要求教师具有较高的专业技能、丰富的表现力、全面发展的授课能力、与学生沟通交流的亲和力等。同时更重要的是教师要了解不同学生的各方面差异,对他们进行因材施教。以确保他们成长为健康、稳定、快乐的舞者与未来授业者。

    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

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.

Mediante un SIG, los resultados de los parámetros estudiados, las coordenadas de los sitios y la cartografía relacionada se incorporaron en la base de datos del software ArcGIS 9.3 y asociados a las herramientas de análisis espacial para realizar interpolación y generación de mapas temáticos de la aptitud del suelo para piscicultura. Los valores promedio de pH (6,67±0,76, MO (0,51±0,34% y P (19,62±26,99 ppm se encontraron dentro del rango para cultivo de peces. La alta concentración de Fe (26,34±22,65 ppm fue considerada la variable más crítica para la aptitud del suelo para la piscicultura, principalmente en las áreas con pH bajo. El mapa de aptitud del suelo, generado con la integración de las variables estudiadas, permitió identificar 123.625 ha como moderadamente aptas (67,4%, 53.909 ha como aptas (29,3% y solamente 6.093 fueron consideradas no aptas (3,3%. Sin embargo, este resultado debe ser correlacionado con otras variables como topografía, cobertura vegetal, uso del suelo, disponibilidad hídrica, calidad hídrica, capacidad de drenaje, restricciones ambientales y aspectos socioeconómicos de la región.Abstract.

    Full Text Available Se realizó un estudio geocientífico para la evaluación de la aptitud para la urbanización en la cuenca carbonífera de Río Turbio. Este estudio incluyó la caracterización de los recursos naturales: suelos, agua y paisaje y la evaluación de áreas de riesgo natural y antrópico, la pérdida de espacios verdes y tierras agrícolas. La zona implicada se encuentra localizada en el extremo SO de la provincia de Santa Cruz. Conforma la llamada cuenca carbonífera del Río Turbio. Las localidades de Río Turbio y 28 de Noviembre exhiben el mayor número poblacional. Estas poblaciones se desarrollaron a partir de la actividad minera y ganadera. En función de las características geológicas, geomorfológicas, bióticas, geotécnicas, hidrológicas y edafológicas, se han diferenciado 7 unidades de paisaje. A partir de la información generada previamente y como insumo básico para la producción del plan de desarrollo urbano, se ha realizado un mapa de aptitud para la urbanización del área. Las unidades de paisaje con mejores posibilidades para la expansión urbana son dos: Morenas con estepa herbácea y planicies glacifluviales con estepa mixta. La unidad paisaje erosivo glaciar con bosque y la unidad terrazas fluviales son aceptables para la urbanización, mientras que las unidades: Cañadones y pendientes aluvio-coluviales, serranías poligenéticas terciarias y mallines y bajos, son inapropiadas para la urbanización, por diferentes motivos.

    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.

    The product test asks the product of a quantity index number and a price index number to equal the corresponding value change. The literature treats the product test as being so important that it is used to identify acceptable index number pairs, and to construct implicit index numbers when an otherwise desirable pair fails the test. We treat the product test as a hypothesis to be tested, and we provide an empirical application.

For this, reproductive aptitude tests before service, which include serving capacity (SC evaluation through a practical and trustworthy pen test should be carried out. This study was carried out to compare different SC pen tests. In experiment 1, done in December, Kilgour, Laborde and Blockey's test measured similar SC (p < 0.05. Nevertheless, in experiment 2 done in February, Laborde and Blockey's tests evaluated SC differently (p 0.05. Differences may be explained as a consequence of reproductive seasonality in rams. In both experiments, the tests estimated SC similarly whether they were done at 20 or 40minutes (p < 0.05. This allows to shorten the evaluation time for tests. This is supported in both experiments by the high correlation between reaction time to first service and total number of services (r = -0.59 y r = -0.56; p < 0.01. These results allow to think that Laborde's test may be a valid alternative of pen test of SC in adult rams in December as a complement to the classical reproductive fitness test

    with average values of air temperature for a growing season to characterize the agro-climatic aptitude. For table grapes it was observed that the region has no thermal limitation, however higher both sugar contents and grape yield would be obtained in the areas with higher values of air temperature. In relation to wine grape, it was observed that there are some thermal limitations for the wine quality, depending on the pruning date, being higher the alcohol content and lower acidity, in wines elaborated under conditions with higher values of air temperature. In relation to table grapes, the best pruning dates are between June and September, being highlighted the west areas of Bahia, Pernambuco, Paraíba and almost all areas of Rio Grande do Norte, Ceará, Piauí and Maranhão. Considering wine grapes, the best agro-climatic aptitude is for pruning dates from May to June, with highlights for the states of Bahia, Pernambuco, Paraíba, Alagoas and Sergipe, and a southeast area of Maranhão state.

    Full Text Available The field of Mathematics requires a lot of critical thinking and problem solving. These skills are honed as early as the basic education years of the students. Teacher training institutions should make it a necessity that they are able to cater to pre-service teachers who will be able to meet the demands of mathematics education. This paper aimed to construct, validate and determine the Differential Item Functioning (DIF of a problem solving test for pre-service mathematics teachers. This test will later be used as a basis for designing interventions to improve the mathematical aptitude of pre-service teachers. Two universities were chosen with 100 third year students taking Bachelor of Science in Secondary Education major in Mathematics. The tests were constructed and validated by experts before administration to the participants. The participants took the examination and the test was improved based on the results of the item analysis. Differential Item Functioning was also tested using the Standardization Method. The study led to the development of a 60-item validated test on problem solving. After subjecting to DIF analysis, it was found that the two groups tested performed with no significant difference between individuals of similar abilities. The test yielded norm values per sub-skill of the test which will help gauge pre-service mathematics teachers’ problem-solving skills.

    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.

  9. Urine test.

    Science.gov (United States)

    1996-08-23

    On August 6, 1996, the Food and Drug Administration (FDA) approved the first urine test to detect HIV antibodies. The FDA states that the urine test, developed by Calypte Biomedical Corp. of Berkeley, CA, should not be used to screen donors at blood banks and should be used only as a supplemental diagnostic tool because it is not as accurate as the standard blood-based test. The test, for use only by health care professionals and insurance companies, will be marketed by Seradum Inc. of Indianapolis under the trade name Sentinel. The price will be $40 to $50, comparable to the recently approved saliva-based tests. Advocates of the urine test say it is safer, easier, and less intrusive than blood testing. Critics say the tests are too unreliable and fear that the urine samples used in drug testing in the workplace also could be used to screen out HIV-positive job applicants. PMID:11363733

  12. Test quality

    International Nuclear Information System (INIS)

    This document discusses inservice testing of safety-related components at nuclear power plants which is performed under the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (the Code). Subsections IWP and IWV of Section XI of the Code state test method and frequency requirements for pumps and valves respectively. Tests vary greatly in quality and frequency. 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

  4. Proficiency tests organisation as a tool of improvement of radioactivity measurement quality in the frame of environmental survey

    International Nuclear Information System (INIS)

    In order to ensure the quality of environmental radioactivity measurements made by laboratories, a laboratory certification system has been set up in France by ASN (French Authority for Nuclear Safety). Every year, the IRSN (French Institute for Radiation protection and Nuclear Safety) organizes several proficiency tests, in support of ASN, for the laboratory agreement. These tests can be defined as aptitude tests where the measurement results obtained on an identical sample by different laboratories are compared to a reference value. These tests concern the measurement of radionuclides beta and gamma emitters, beta pure emitters and artificial alpha emitters as well as radionuclides of the natural chain of uranium and thorium. This poster describes the test procedure and the preparation of the samples. The samples will be measured by IRSN to check homogeneity, stability and to determine reference value, and by laboratories to get the agreement. These proficiency tests permit to make sure that French and foreign laboratories have the technical capability to provide quality measurement results

    Analytical methods for combining flight acceleration and strain data with shake test mobility data to predict the effects of structural changes on flight vibrations and strains are presented. This integration of structural dynamic analysis with flight performance is referred to as analytical testing. The objective of this methodology is to analytically estimate the results of flight testing contemplated structural changes with minimum flying and change trials. The category of changes to the aircraft includes mass, stiffness, absorbers, isolators, and active suppressors. Examples of applying the analytical testing methodology using flight test and shake test data measured on an AH-1G helicopter are included. The techniques and procedures for vibration testing and modal analysis are also described.

We then consider the trace test for subvarieties of products of projective spaces working with multihomogeneous witness sets. We show how a dimension reduction based on Bertini's Theorem leads to a practical trace test in this case involving a curve in a small-dimensional affine space.

How do you make sure it continues to do so as you update, modify, and add functionality? Software testing is an integral part of code validation and writing tests should be a requirement for any software project. I will talk about Python-based tools that make managing and running tests much easier and explore some statistics for projects hosted on GitHub that contain tests.

    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.

  15. Prediction of motor imagery based brain computer interface performance using a reaction time test.

    Science.gov (United States)

    Darvishi, Sam; Abbott, Derek; Baumert, Mathias

    2015-08-01

    Brain computer interfaces (BCIs) enable human brains to interact directly with machines. Motor imagery based BCI (MI-BCI) encodes the motor intentions of human agents and provides feedback accordingly. However, 15-30% of people are not able to perform vivid motor imagery. To save time and monetary resources, a number of predictors have been proposed to screen for users with low BCI aptitude. While the proposed predictors provide some level of correlation with MI-BCI performance, simple, objective and accurate predictors are currently not available. Thus, in this study we have examined the utility of a simple reaction time (SRT) test for predicting MI-BCI performance. We enrolled 10 subjects and measured their motor imagery performance with either visual or proprioceptive feedback. Their reaction time was also measured using a SRT test. The results show a significant negative correlation (r ≈ -0.67) between SRT and MI-BCI performance. Therefore SRT may be used as a simple and reliable predictor of MI-BCI performance. PMID:26736893

    Sharing the same filtering function, LSAT and its corresponding Chinese version JMT are capable of being studied comparatively. Historically, LSAT was the by-product of Measure Movement and motivated by law school recruitment departments, while JMT was affiliated to new-born JM system and took place at the same time JM was founded. As for the content of both assessments, LSAT is essentially an aptitude test and JMT is an achievement examination. LSAT is future-oriented by predicting test takers’ability and aptitude of learning and practicing law, while JMT is a backforward test which indicates law competence achieved previously by testees. Those mentioned features of LSAT in the present paper could inspire the future reform of JMT.%基于美国LSAT与我国法律硕士联考所具功能的一致性,本文对二者展开比较研究。从历史角度看,LSAT是标准化考试进程与法学院招生需求扩张的产物,法硕联考则附属于法硕制度的产生;考核内容方面,LSAT注重对于学能的评定,测试内容与学科专业知识无关,法硕联考则以法律专业知识的掌握情况为检验标准;评价取向方面,LSAT旨在预测申请者学习法律或是从事法律职业的潜质,具有前瞻性,法硕联考是对具体法律专业知识识记、理解、应用能力的总结,具有检测性。LSAT的评价理念对于我国法硕联考改革有一定的借鉴意义。

    In the present study, demonstration test was made on technology to promote the pozzolan reaction, by adding fly ash with desulfurization sludge, produced from the stack gas desulfurization process in the thermal power station, and then mixing it with lime (the mixture is called Poz-o-Tec.). That test was continued for a period of three years. In the first term of year, basic mixture test was made on domestic fly ash. In the second term of year, pursuit survey was made by, as a a basic on-site test, producing Poz-o-Tec, and filling land and structuring roadway subgrade with it by general purpose heavy equipment in the station. In the third term of year, usability survey was commenced with using a practical use scale plant, supplying material and constructing actual public roadway with it. While simultaneously, aptitude test was made as water-barrier landfill material, to stop water from landfilled bank and water reservoir, and surface soil-improving material for the soft ground. As a result of those serial tests, the Poz-o-Tec was known to give a high possibility of being commercialized as civil construction use material. 20 figs., 12 tabs.

  2. Predictive validity of five cognitive skills tests among women receiving engineering training

    Science.gov (United States)

    Wittig, Michele Andrisin; Hennix Sasse, Sharon; Giacomi, Jean

    This article addresses two sets of theoretical and practical issues related to increasing the percentage of women engineers. First, the measurement of women's aptitude for and changes in skills during engineering training was assessed. Five cognitive skills tests were administered in a one-group pretest-posttest design to 24 baccalaureate women enrolled in an eleven-month engineering training course. Significant increases in skills were shown on three of the five assessments. Scores on a mathematics anxiety scale and a measure of conservation of horizontality are also reported. Second, the relationship of academic and demographic information and cognitive skills to degree of success in the program is reported. Pretraining spatial visualization scores predicted posttraining GPA group membership. The results are compared and contrasted with those of studies of male undergraduates. Implications are drawn concerning the ways in which evaluations of such programs can contribute to our understanding of the changes in skills that occur with training in engineering and of the factors that predict success in such programs.

    The changes made to the curricula and assessment systems in the UK have resulted in pathology specialty-training programmes which assess trainees on a regular (weekly or monthly) basis. An end of first year assessment tests their aptitude for the specialty, the FRCPath examinations taking place after at least one to two (part 1) and three to four (part 2) years of training respectively, and multi-source feedback is undertaken in years 1, 3 and 5. With regular educational appraisal, this constitutes cohorts of well-assessed and supported trainees. The assessments are blueprinted to the curriculum, ensuring adequate assessment coverage of curriculum content within workplace-based assessments (WPBA), objective structured pathology examinations and the FRCPath examinations. Notably, generic non-clinical attributes and behavioural skills such as leadership and management skills can be covered in the WPBA. Many of these changes are evolutionary in nature, but some have been imposed by continuously increasing regulatory requirements. Whilst additional information is generated, the increased amount of assessment of trainees has led to complaints that trainees do not acquire enough practical experience in the laboratory. It will be important to find the balance between didactic teaching with formal assessment, and apprenticeship-style, practical hands-on learning. PMID:26374106

  5. Development of a new test to evaluate the decontaminable aspect of coatings

    International Nuclear Information System (INIS)

    Nuclear power plants coatings are selected in order to make surfaces easily decontaminated. The standards procedures present several disadvantages, related to the use of contaminated liquids. EDF Ceidre wishes to invent a new practice, cleaner and more accurate. The development of a new test needs several stages. The most problematic is the identification of the coatings parameters which contribute to the aptitude of contamination and decontamination. One of the most obvious parameters, today investigated by EDF, seems to be the surface quality of coatings (flatness and brightness). This presentation underlines the link recently detected between the surface quality of coatings and their decontamination. Surface aspect, and notably roughness, is a parameter important to understand contamination and decontamination features of the coatings. By increasing the number of tests, micro topography and numerical imagery analysis may allow to distinguish the systems clearly out-criteria. Even if it can't explain everything, the surface aspect of coatings has an important influence on the NF T 30-901 test results. This leads to several conclusions: The quality of the samples surfaces must be checked before any test because the roughness, the presence of cracks and others defects impact the decontamination ability of the coatings and the test results. The qualification of coatings is important to ensure their durability and resistance to the daily wear being able to lead to defects. The quality of work realization represents also a dominating parameter to prevent defects. Therefore, qualification of coatings and quality of their application contribute to the radiological cleanliness of the plants. The level of decontamination ability of painted surfaces in nuclear power plants depends primarily on the care taken to coatings, and in particular to their follow-up and regular replacement. In conclusion, the coatings maintenance in power plants can play a fundamental part in

    Auxiliary Power Unit (APU) fuel (hydrazine) tanks have had to be removed from the Columbia Shuttle (OV-102) because they have been in service for 11 years, which is the limit of their useful life. As part of an effort to determine whether the useful life of the fuel tanks can be extended, examination of the ethylene propylene rubber (EPR) diaphragm and the metal from one of the APU tanks is required. The JSC Propulsion and Power Division has requested White Sands Test Facility (WSTF) to examine the EPR diaphragm thoroughly and the metal casing generally from one tank. The objective is to examine the EPR diaphragm for signs of degradation that may limit the life of its function in the APU propellant tank. The metal casing will also be examined for signs of surface corrosion.

    Applied researchers often use tests based on contingency tables in preliminary data analysis and diagnostic testing. We show that many of such tests may be alternatively implemented by testing for coecient restrictions in linear regression systems (as a rule, employing the Wald test). This uni es the theories of regression analysis and contingency tables, sheds more light on intuitive contents of contingency table tests, and provides a more convenient and familiar tool for practitioners.

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

    Science.gov (United States)

    Camporesi, Silvia; McNamee, Mike J

    2016-03-01

    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. PMID:26757798

    Background: Student's two-sample t test is generally used for comparing the means of two independent samples, for example, two treatment arms. Under the null hypothesis, the t test assumes that the two samples arise from the same normally distributed population with unknown variance. Adequate...... control of the Type I error requires that the normality assumption holds, which is often examined by means of a preliminary Shapiro-Wilk test. The following two-stage procedure is widely accepted: If the preliminary test for normality is not significant, the t test is used; if the preliminary test rejects...... the null hypothesis of normality, a nonparametric test is applied in the main analysis. Methods: Equally sized samples were drawn from exponential, uniform, and normal distributions.

    Full Text Available El valle de Guasave, Sinaloa, es eminentemente agrícola y cuenta con comunidades rurales que se abastecen de agua para su uso doméstico mediante pozos ubicados en sus predios. La actividad económica y social de dicho valle demanda agua para ambas actividades, por lo que su extracción se ha desplazado hacia la zona costera, siendo importante conocer los mecanismos naturales que controlan la composición química del agua, su calidad, su variación temporal atendiendo a la aptitud de uso agrícola o doméstica. Para determinar el mecanismo que controla la composición química del agua se utilizó el diagrama de Gibbs, encontrándose que el mecanismo dominante es por evaporización-meteorización. Respecto al agua para uso doméstico se utilizó el índice de calidad PHASECH, encontrándose que el agua cumple con el mismo sólo en las proximidades del río Sinaloa. En cuanto a la aptitud de uso agrícola del agua se utilizó el diagrama de Wilcox, encontrándose que sólo el 48% del agua de la zona se clasifica como buena a admisible. En cuanto al riesgo de salinización o sodificación del suelo por el uso del agua de riego, se usó el diagrama de salinidad del Departamento de Agricultura de Estados Unidos de Norteamérica, encontrándose que el 35% del agua se ubica en la zona C3S1. La relación obtenida entre los sólidos totales disueltos y la conductividad eléctrica del agua, fue EC = 1.65 STD. Se concluye además, que el acuífero del río Sinaloa es altamente sensible a la salinización por su carácter costero y presencia de cuerpos evaporíticos alejados de la línea de costa, por lo que, el peligro de intrusión salina ante un periodo de sequía es latente. La presencia del río Sinaloa es un elemento relevante de recarga que permite mantener el agua subterránea en condiciones aptas para la agricultura y muy cercanas a las requeridas para uso doméstico.The Guasave valley, Sinaloa is mainly agricultural.

Strength tests are performed to determine and verify the amount of the bundle shape distortion which is against the side-stops when the bundles are refuelling. There are two cases of strength test; one is the double side-stop test which simulates the normal bundle refuelling and the other is the single side-stop test which simulates the abnormal refuelling. the strength test specification requires that the fuel bundle against the side-stop(s) simulators for this test were fabricated and the flow rates were controlled to provide the required conservative hydraulic forces. The test rig conditions of 120 deg C, 11.2 MPa were retained for 15 minutes after the flow rate was controlled during the test in two cases, respectively. The bundle loading angles of number 13- number 15 among the 15 bundles were 67.5 deg CCW and others were loaded randomly. After the tests, the bundle shapes against the side-stops were measured and inspected carefully. The important test procedures and measurements were discussed as follows.

  6. Vendor System Vulnerability Testing Test Plan

    Energy Technology Data Exchange (ETDEWEB)

    2005-01-01

    The Idaho National Laboratory (INL) prepared this generic test plan to provide clients (vendors, end users, program sponsors, etc.) with a sense of the scope and depth of vulnerability testing performed at the INL’s Supervisory Control and Data Acquisition (SCADA) Test Bed and to serve as an example of such a plan. Although this test plan specifically addresses vulnerability testing of systems applied to the energy sector (electric/power transmission and distribution and oil and gas systems), it is generic enough to be applied to control systems used in other critical infrastructures such as the transportation sector, water/waste water sector, or hazardous chemical production facilities. The SCADA Test Bed is established at the INL as a testing environment to evaluate the security vulnerabilities of SCADA systems, energy management systems (EMS), and distributed control systems. It now supports multiple programs sponsored by the U.S. Department of Energy, the U.S. Department of Homeland Security, other government agencies, and private sector clients. This particular test plan applies to testing conducted on a SCADA/EMS provided by a vendor. Before performing detailed vulnerability testing of a SCADA/EMS, an as delivered baseline examination of the system is conducted, to establish a starting point for all-subsequent testing. The series of baseline tests document factory delivered defaults, system configuration, and potential configuration changes to aid in the development of a security plan for in depth vulnerability testing. The baseline test document is provided to the System Provider,a who evaluates the baseline report and provides recommendations to the system configuration to enhance the security profile of the baseline system. Vulnerability testing is then conducted at the SCADA Test Bed, which provides an in-depth security analysis of the Vendor’s system.b a. The term System Provider replaces the name of the company/organization providing the system

  8. EVALUATION OF CRUSTING APTITUDE ON SIEVED SOILS. ANEWAPPARATUS

    Directory of Open Access Journals (Sweden)

    Full Text Available Soil surface crusting has severe agricultural and environmental effects. The action of beating rains can destroy soil surface structure and in some cases lead to surface sealing and crusting which, in turn, reduce soil conductivity, seed emergence and increase the runoff hazard. The susceptibility of different soils to crusting was studied by a new experimental apparatus and model. A micro rain – simulator mounted on a rotating disc sprinkles water on soil sample and after a certain time (or revolutions of the disc the water ponded on soil surface completely percolates and water is again applied to the soil surface. The model was used to follow the variation of soil hydraulic conductivity as a function of time or total water applied during the crust formation. The effects of soil sieved crumbs and duration of pre-saturation were investigated during the crust formation. For some soils crusting decreases along the sprinkling events, with the diameter of aggregates presenting high values; sometimes significant structural deterioration in the aggregate of higher diameter occurs after a initial resistance to crusting as evidenced by a sharp reduced hydraulic conductivity. The role of the pre-saturation time seem more important for less resistant soils.

  5. Localizing Test Power Consumption for Scan Testing

    Institute of Scientific and Technical Information of China (English)

    XIANG Dong; LI Kai-wei

    2005-01-01

    A two stage scan architecture is proposed to do low powerand low test application cost scan testing. The first stage includes multiple scan chains, where each scan chain is driven by a primary input. Each scan flip-flop in the multiple scan chains drives a group of scan flip-flops. The scan flip-flop in the multiple scan chain and the scan flipflop driven by it are assigned the same values for all test vectors. Scan flip-flops in the multiple scan chains and those in the second stage use separate clock signals, but the design for testability technqiue needs only one clock. The proposed scan architecture localizes test power consumption to the multiple scan chains during test application. Test signals assigned to scan flip-flops in the multiple scan chains are applied to the scan flip-flops in the second stage after the test vector has been applied to the multiple scan chains. This technique can make test power consumption very small.

    The desire and ability to fly Unmanned Aircraft Systems (UAS) in the National Airspace System (NAS) is of increasing urgency. The application of unmanned aircraft to perform national security, defense, scientific, and emergency management are driving the critical need for less restrictive access by UAS to the NAS. UAS represent a new capability that will provide a variety of services in the government (public) and commercial (civil) aviation sectors. The growth of this potential industry has not yet been realized due to the lack of a common understanding of what is required to safely operate UAS in the NAS. NASA's UAS Integration into the NAS Project is conducting research in the areas of Separation Assurance/Sense and Avoid Interoperability, Human Systems Integration (HSI), and Communication to support reducing the barriers of UAS access to the NAS. This research is broken into two research themes namely, UAS Integration and Test Infrastructure. UAS Integration focuses on airspace integration procedures and performance standards to enable UAS integration in the air transportation system, covering Sense and Avoid (SAA) performance standards, command and control performance standards, and human systems integration. The focus of Test Infrastructure is to enable development and validation of airspace integration procedures and performance standards, including the integrated test and evaluation. In support of the integrated test and evaluation efforts, the Project will develop an adaptable, scalable, and schedulable relevant test environment capable of evaluating concepts and technologies for unmanned aircraft systems to safely operate in the NAS. To accomplish this task, the Project will conduct a series of Human-in-the-Loop and Flight Test activities that integrate key concepts, technologies and/or procedures in a relevant air traffic environment. Each of the integrated events will build on the technical achievements, fidelity and complexity of the previous tests and

    International Nuclear Information System (INIS)

    Test IE-5, conducted in the Power Burst Facility at the Idaho National Engineering Laboratory, employed three 0.97-m long pressurized water reactor type fuel rods, fabricated from previously irradiated zircaloy-4 cladding and one similar rod fabricated from unirradiated cladding. The objectives of the test were to evaluate the influence of simulated fission products, cladding irradiation damage, and fuel rod internal pressure on pellet-cladding interaction during a power ramp and on fuel rod behavior during film boiling operation. The four rods were subjected to a preconditioning period, a power ramp to an average fuel rod peak power of 65 kW/m, and steady state operation for one hour at a coolant mass flux of 4880 kg/s-m2 for each rod. After a flow reduction to 1800 kg/s-m2, film boiling occurred on one rod. Additional flow reductions to 970 kg/s-m2 produced film boiling on the three remaining fuel rods. Maximum time in film boiling was 80s. The rod having the highest initial internal pressure (8.3 MPa) failed 10s after the onset of film boiling. A second rod failed about 90s after reactor shutdown. The report contains a description of the experiment, the test conduct, test results, and results from the preliminary postirradiation examination.

  18. Pancreatic exocrine function testing

    International Nuclear Information System (INIS)

    It is important to understand which pancreatic function tests are available and how to interpret them when evaluating patients with malabsorption. Available direct tests are the secretin stimulation test, the Lundh test meal, and measurement of serum or fecal enzymes. Indirect tests assess pancreatic exocrine function by measuring the effect of pancreatic secretion on various nutrients. These include triglycerides labeled with carbon 14, cobalamin labeled with cobalt 57 and cobalt 58, and para-aminobenzoic acid bound to a dipeptide. Of all these tests the secretin stimulation test is the most accurate and reliable if done by experienced personnel. However, the indirect tests are simpler to do and appear to be comparable to the secretin test at detecting pancreatic exocrine insufficiency. These indirect tests are becoming clinically available and clinicians should familiarize themselves with the strengths and weaknesses of each

  19. Grimsel test site. Overview and test programs

    International Nuclear Information System (INIS)

    Knowledge of the host rock and surrounding rock strata is of fundamental importance for concepts which provide for final disposal of radioactive waste in geological formations. Taking the studies in the Stripa Rock Laboratory into account, the objectives of the Grimsel Test Site were defined as follows: checking the applicability of foreign research results to geological conditions in Switzerland; carrying out specific experiments which are necessary in the context of the Nagra disposal concepts; acquisition of know-how in planning, implementation and interpretation of underground tests in different experimental areas; acquisition of practical experience in development, testing and use of experimental apparatus and measurement methods. At Grimsel, experiments are to be carried out in the following fields: excavation tests; migration; rock stress measurements; neo-tectonics; geophysics; heat-induced processes; hydrogeology; laboratory experiments. Various tests are already under way. The Grimsel Test Site was established between April 1983 and May 1984. It lies at a depth of 450 m under the Juchlistock and is reached by an access tunnel. The Test Site is operated by Nagra. The experiments are carried out by Nagra and the following two German research establishments: the 'Bundesanstalt fuer Geowissenschaften und Rohstoffe (BGR)' and the 'Gesellschaft fuer Strahlen- und Umweltforschung (GSF)', both under the auspices of the German 'Bundesministerium fuer Forschung und Technologie (BMFT)'.

    The paper describes a new model of exploiting parallelism in testing of VLSI circuits. A circuit at the register transfer level is denoted as an RTL circuit. The model utilizes the concept of TACG (Test Application Conflict Graph). For the testing process the resource utilization model is defined and used for the TACG construction.  Different conflicts that must be taken into account during an RTL circuit test scheduling are presented. The problem of concurrent test application is transf...
