    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.

    2001-02-01

    The EFCS/QUATE aptitude test is an important measure for evaluating quality in cervical cytopathology and for assessing the level of experience and competence in cervical cancer screening. The test, set up in the 1990s by the ECTP/CCS working party, has been performed since 1992 in several European countries: United Kingdom, The Netherlands, Germany, Denmark, Portugal, Slovenia, Hungary and Italy. In Italy, the test has been performed at the Istituto Superiore di Sanità in 1992 and 1993 and in some Italian universities (Padua 1993, Turin 1994, Sassari 1995, Naples 1996, Messina 1998) and in one hospital (Genoa 1997). The minimum passing score is 60/100 (60% in all sections). The aptitude test for cytotechnologists includes: a written test (50 multiple choice questions); a practical test (screening 10 unmarked cervical smears; spot test of 20 slides with a fixed field of view); and an oral test, for borderline candidates when necessary (60%) or for the diploma with 'distinction' (95%). Successful candidates receive the Certificate of Aptitude in Gynecological Cytotechnology and are entitled to use the initials CT (EFCS-GYN) after their names for professional purposes. The aptitude test for anatomopathologists includes an oral test and a practical test (screening 5 unmarked cervical smears, spot test of 20 slides with a fixed field of view, and reading and diagnosing 3 complex cases). Successful candidates receive the certificate of gynecological cytopathology. The first aptitude test for anatomopathologists in Italy, organized and endorsed by the Istituto Superiore di Sanità in collaboration with SIAPEC (Italian Society of Pathological Anatomy and Cytopathology) and in agreement with the European guidelines for cervical cancer screening, was performed on 18 December 1997 in Rome. The total number of aptitude tests carried out in Europe is 15 for cytotechnologists and 4 for anatomopathologists. A total of 317 cytotechnologists and 73 anatomopathologists has taken

    The conative domain of aptitude constructs spans the domains of individual differences in motivation and volition. This research sampled a broad range of conative constructs, including achievement motivation, anxiety, goal orientations, and interest, among others. The purpose was threefold: (a) to explore relationships among conative constructs hypothesized to affect student commitment to learning and subsequent performance, (b) to determine whether or not individual differences in conative constructs were associated with the learning activities and time-on-task of students learning science, and (c) to ascertain whether or not the conative constructs and the time and activity variables were associated with performance differences in a paper-and-pencil science recall measure. This research consisted of three separate studies. Study I involved 60 U.S. college students. In Study II, 234 Canadian high school students participated. These two studies investigated the construct validity of a selection of conative constructs. A principal components analysis of the measures was undertaken and yielded seven components: Pursuit of Excellence, Evaluation Anxiety, Self-Reported Grades, Science Confidence, Science Interest vs. Science Ambivalence, Performance Orientation, and Verbal Ability. For Study III, 82 Canadian high school students completed the same conative questionnaires as were administered in Study II. A computerized environment patterned after an internet browser allowed students to learn about disease-causing microbes. The environment yielded aggregate measures of the time spent learning science, the time spent playing games, the number of games played, and the number of science-related learning activities engaged in by each student. Following administration of the computerized learning environment, students were administered a paper-and pencil science recall measure. Study III found support for the educational importance of the conative variables. Among the

    Full Text Available 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.

    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

  19. Tweezer dexterity aptitude of dental students.

    2007-08-01

    The rationale for using the Perceptual Ability Test (PAT) as a component in admissions decisions for dental schools is that candidates vary in an underlying aptitude that is predictive of degree of success in technique course performance and perhaps in clinical performance. There have been periodic attempts to identify tests that more directly measure manual dexterity aptitude that would supplement the predictive power of admissions decisions. Previous research has demonstrated that a commercially available "speeded" tweezer dexterity test (Johnson O'Connor Test #32022) is not associated with performance in dental school or dental practice. Our research investigated both Test #32022 and Test #18 that measure both speed and accuracy as potential predictors of dental school performance in technical and clinical courses. This article reports the results of a longitudinal, comparative study of tweezer dexterity scores for students at the University of the Pacific School of Dentistry during their first and last quarters in school. The goals of the study were to 1) evaluate the correlation between beginning students' scores on two different types of tweezer dexterity tests; 2) compare dental students' scores to normative data for the general population; 3) determine the effect of a dental curriculum on students' performance on Test #18; and 4) evaluate the two tests as potential dental school admission screening instruments in comparison to the PAT. Fifty first-quarter students were tested from a class of 134. Forty-nine of these students were retested on Test #18 during their final quarter. The predictor value of the initial scores for the two dexterity tests was assessed for seven outcome measures reflecting student technique performance. Analysis showed a significant correlation (r=0.318, ptests. The difference between the norm mean (41.58) and the dental student mean for Test #18 (40.42) was not significant (p>0.05).

    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.

  6. Personality factors as predictors of foreign language aptitude

    Adriana Biedroń

    2011-12-01

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

    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.

    2011-06-01

    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.

    Acknowledging that individuals' preferences for learning vary, faculty in an undergraduate nursing program questioned whether a student's learning style is an indicator of aptitude in developing concept maps. The purpose of this research was to describe the relationship between nursing students' learning style preference and aptitude for concept maps. The sample included 120 undergraduate students enrolled in the adult health nursing course. Students created one concept map and completed two instruments: the Learning Style Survey and the Concept Map Survey. Data included Learning Style Survey scores, grade for the concept map, and grade for the adult health course. No significant difference was found between learning style preference and concept map grades. Thematic analysis of the qualitative survey data yielded further insight into students' preferences for creating concept maps.

  19. The benefits of completing homework for students with different aptitudes in an introductory physics course

    CERN Document Server

    Kontur, F J

    2013-01-01

    We examine the relationship between homework completion and exam performance for students having different physics aptitudes for five different semesters of an introductory electricity and magnetism course. 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 ...

  20. Using dramatic role-play to develop emotional aptitude

    Directory of Open Access Journals (Sweden)

    Russell Dinapoli

    2009-12-01

    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.

  1. Researching Aptitude in a Process-based Approach to Foreign Language Writing Instruction

    Directory of Open Access Journals (Sweden)

    Abbas Zare-ee

    2014-10-01

    Full Text Available In the study reported here, we explored writing processes employed by 70 undergraduate learners of English as a Foreign Language (EFL through questionnaires and think-aloud protocols. Then we looked for possible differences in the writing processes employed by high- and low-aptitude learners. We observed that learners with higher aptitude scores devoted more attention to clausal complexity than those with lower levels of aptitude. Moreover, they resorted less frequently to their mother tongue while writing texts in English. High-aptitude EFL learners also used more global planning strategies than their low-aptitude peers and edited while writing much more frequently. Our review showed that even though aptitude has been extensively researched in second language acquisition and shown to correlate with the level of success in different skills, it has rarely been considered in relation to writing processes. We suggest that, as classroom teachers, EFL writing instructors accumulate and incorporate knowledge of their students’ aptitude in deploying their teaching strategies.

    In a replication of Turkheimer, Haley, Waldron, D'Onofrio, Gottesman II (2003, Socioeconomic status modifies heritability of IQ in young children. Psychological Science, 14:623-628), we investigate genotype-environment (G x E) interaction in the cognitive aptitude of 839 twin pairs who completed the National Merit Scholastic Qualifying Test in 1962. Shared environmental influences were stronger for adolescents from poorer homes, while genetic influences were stronger for adolescents from more affluent homes. No significant differences were found between parental income and parental education interaction effects. Results suggest that environmental differences between middle- to upper-class families influence the expression of genetic potential for intelligence, as has previously been suggested by Bronfenbrenner and Ceci's (1994, Nature-nurture reconceptualized in developmental perspective: a bioecological model Psychological Review, 101:568-586) bioecological model.

    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 (ptest 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.

  4. Language aptitude for pronunciation in advanced second language (L2) learners: behavioural predictors and neural substrates.

    2013-12-01

    Individual differences in second language (L2) aptitude have been assumed to depend upon a variety of cognitive and personality factors. Especially, the cognitive factor phonological working memory has been conceptualised as language learning device. However, strong associations between phonological working memory and L2 aptitude have been previously found in early-stage learners only, not in advanced learners. The current study aimed at investigating the behavioural and neurobiological predictors of advanced L2 learning. Our behavioural results showed that phonetic coding ability and empathy, but not phonological working memory, predict L2 pronunciation aptitude in advanced learners. Second, functional neuroimaging revealed this behavioural trait to be correlated with hemodynamic responses of the cerebral network of speech motor control and auditory-perceptual areas. We suggest that the acquisition of L2 pronunciation aptitude is a dynamic process, requiring a variety of neural resources at different processing stages over time.

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

    2016-01-01

    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.

    Newton, Sarah; Moore, Gary

    Formal writing assignments are commonly used in nursing education to develop students' critical thinking skills, as well as to enhance their communication abilities. However, writing apprehension is a common phenomenon among nursing students. It has been suggested that reading and English aptitudes are related to formal writing ability, yet neither the reading nor the English aptitudes of undergraduate nursing students have been described in the literature, and the relationships that reading and English aptitude have with formal writing ability have not been explored. The purpose of this descriptive correlational study was to describe writing apprehension and to assess the relationships among reading and English aptitude and discipline-specific formal writing ability among undergraduate nursing students. The study sample consisted of 146 sophomores from one baccalaureate nursing program. The results indicated that both reading and English aptitude were related to students' formal writing ability.

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

  11. 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.

  7. Spatial Processing in Infancy Predicts Both Spatial and Mathematical Aptitude in Childhood.

    2016-10-01

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

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

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

    Introducción: la evaluación de la aptitud clínica se manifiesta en situaciones clínicas problematizadas y el alcance del aprendizaje depende de la cualidad de la estrategia educativa. El objetivo de este estudio fue valorar el alcance de dos enfoques educativos distintos, a fin de desarrollar la aptitud clínica del médico familiar. Métodos: diseño cuasi-experimental, en el que se sortean al azar veinte médicos generales en formación para Medicina Familiar: 10 quedan en estrategia educativa tradicional (EET) y 10 en estrategia educativa promotora de la participación (EEPP). Ambas estrategias se aplicaron durante 24 horas con el mismo contenido. En la EET se aplicó exposición con preguntas; en la EEPP discusión en pequeños grupos. El instrumento de evaluación validado tuvo una confiabilidad de 0.91 con la prueba 20 de Kuder-Richardson. Resultados: antes de la intervención, el grupo EET tuvo una mediana de 124 y el de EEPP, 105 (p = 0.19). Después, el grupo EET tuvo una mediana de 126 y el de EEPP una de 156 (p = 0.012). Se compararon ambos grupos con la prueba U de Mann Whitney. También se compararon los mismos sujetos antes y después de las intervenciones con la prueba de pares igualados de Wilcoxon. Las diferencias encontradas fueron estadísticamente significativas, lo cual no difiere de estudios previos. Conclusión: la aptitud clínica alcanzó mayor desarrollo en la EEPP al ser comparada con la EET.

    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

    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.

  7. Altruistic aptitude: age-dependent influence of temperament and emotional intelligence.

    It is unclear why some people behave altruistically and others do not. This study seeks to determine what psychological features could help predict altruistic behavior. We addressed the issue by examining distinct dimensions of temperament and emotional intelligence and their associations with the level of proaltruistic aptitude in two distant age-groups, young (20-29 years) and senior (60-79 years) persons. The study was one of a self-reported psychometric survey. The major findings were that emotional intelligence, rather than temperament, is strongly associated with the expression of altruistic behavior in both young and senior subjects, despite a general decrease in the characteristics of emotional intelligence in advanced age. We also failed to substantiate the presence of an appreciable difference in the level of declared altruism between the senior and young subjects. High emotional intelligence, often underling social engagement and bonding, seems thus a good predictor of altruistic aptitude to be displayed by a person. The independence of this association of age-changes in emotional agility is suggestive of causal relationship. The study is relevant for an understanding of the enigmatic origins of important social behaviors like altruism.

    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.

    Accurately predicting NCLEX-RN® success has a positive impact on all nursing education stakeholders. This study focused on the ability to predict NCLEX-RN pass rates on the basis of prenursing academic aptitude variables and the Assessment Technologies Institute (ATI) nursing aptitude program. The ATI predictors were the Test of Essential Academic Skills (TEAS) and fi ve ATI subject tests: Fundamentals, Medical Surgical, Nursing Care of Children, Mental Health, and Maternal Newborn. The prenursing variables comprised the prenursing grade point average, a prerequisite communication course, and the ATI TEAS composite subscores of TEAS Reading, TEAS Math, TEAS Science, and TEAS English. This study included participants from four baccalaureate nursing programs in the California State University system. Results of canonical correlation, multiple linear regression, and logistic regression revealed a significant correlation among prenursing, ATI scores, and NCLEXRN fi rst-try pass rates. Prediction of NCLEX-RN success rate using standardized testing data was supported, with the strongest predictors being the ATI Medical Surgical and ATI Mental Health tests.

    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.

    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.

    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.

Seventy four out of 102 students (29 male and 45 female filled in the aptitude scientific model (ASM designed by D’Ottavio & Bassan (1989. For both, Human Genetics and Histology, performance of the students was considered as satisfactory when they reached a minimum of 85% correct answers in their objective periodic and final examinations. Conversely, lower performance was considered as less than satisfactory. The aforementioned 74 students correctly answered 3.89 ± 1.96 of the 12 ASM problems; average for males was 4.50 ± 1.99 and that for females, 3.48 ± 1.83, (p < 0.025.

    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.

    Hill, Emmeline W; Ryan, Donal P; MacHugh, David E

    2012-12-01

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

    2015-03-01

    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.

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

    McGarity, John R., Jr.; Butts, David P.

    This study was designed to determine the relationship among teacher classroom management behavior, student engagement, and student achievement of middle and high school science students. 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.

  16. 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.

    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'.

    Pre-employment assessments must accurately simulate job tasks and demands and select appropriate personnel to be considered effective. This study focussed on the perception of NSW fire-fighters in relation to the validity of the NSW Fire Brigade's pre-employment assessment, the Physical Aptitude Test. A qualitative method was used to gain a precise understanding of fire fighters' opinions of the accuracy of the Physical Aptitude Test. Information letters and consent forms were sent to an urban fire station with interested participants replying via the university. Six participants, who met the inclusion criteria were randomly selected for the study and in-depth, ethnographic, semi-structured interviews were conducted. The fire fighters believed in order for the Physical Aptitude Test to accurately simulate job demands and select the most capable fire fighters', it needed to be more physically demanding. However, participants believed that the "work-simulating" nature of the Physical Aptitude Test provided an accurate indication of the job tasks.

    This study examined the effect of an academic year of direct instruction in the phonology/orthography of Spanish on the native-language skills and foreign-language aptitude of high school women identified as at risk (n = 14) and not at risk (n = 19) for experiencing problems with learning a foreign language. At-risk students received a specialized teaching approach; not-at-risk students received traditional foreign-language instruction. Pre- and posttest results showed that both groups improved significantly on a foreign-language aptitude test, and the at-risk group made significant gains on native-language phonology/orthography measures. Pretest comparisons showed significant between-group differences on several phonological/orthographic measures and the foreign-language aptitude test. Posttest comparisons showed that the not-at-risk subjects still scored significantly higher than at-risk subjects on the foreign-language aptitude measure; no differences were noted on two native-language phonological/orthographic measures. Pre- and posttest comparisons between groups showed that the at-risk group made significantly greater gains than the not-at-risk group on phonological/orthographic measures. Implications for instruction are presented.

  19. General aptitude and the assumption of truth in deductively rational reasoning about probable but false antecedent to consequent relations.

    2010-12-15

    Two experiments (N(1) = 117 and N(2) = 245) on reasoning with knowledge-rich conditionals showed a main effect of logical validity, which was due to the negative effect of counter-examples being smaller for valid than for invalid arguments. These findings support the thesis that some people tend to inhibit background inconsistent with the hypothetical truth of the premises, while others tend to abandon the implicit truth-assumption when they have factual evidence to the contrary. Findings show that adhering to the truth-assumption in the face of conflicting evidence to the contrary requires an investment of time and effort which people with a higher general aptitude are more likely to do.

  1. 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.

  2. Validation of selected temperament and personality questionnaires for diagnosing drivers' aptitude for safe driving. A Polish study.

    2014-09-01

    This paper presents the results of a study aimed at validating psychological questionnaires evaluating temperamental and personality features. It discusses their usefulness in diagnosing drivers' aptitude for safe driving and working as professional drivers. Three psychological questionnaires were validated: the Formal Characteristics of Behaviour - Temperament Inventory (FCB-TI), the Eysenck Personality Questionnaire - Revised and Short Scale (EPQ-R (S)) and the Impulsiveness Questionnaire (IVE). Three groups of drivers (n=246) aged 19-75 participated in the study. Group I (professional drivers; n=96) and Group II (nonprofessional drivers; n=75) had never been involved in road crashes, whereas Group III (nonprofessional drivers; n=75) were offenders involved in fatal injury road crashes. Criterion-related validity, Cronbach's alpha and Guttman split-half reliability coefficient were in assessing the psychometric properties of the questionnaires. There were some significant differences between Groups II and III for most traits. However, contrary to expectations, higher Emotional Reactivity, Perseveration and lower Endurance as well as higher Neuroticism, Impulsiveness and Venturesomeness were determined for Group II than for Group III. Additionally, the temperament and personality profile of Group II turned out to be less fitted to the profile of safe drivers than that of Group III, whose profile was actually similar to that of Group I. This seems to result from a high tendency for a positive self-presentation among Group I and Group III (a significantly higher result on the Lie scale in comparison with Group II). The results suggest that if psychological tests are to decide on whether a person may be a professional driver or may drive vehicles, the three questionnaires (FCB-TI, EPQ-R(S) and IVE) do not provide a valid diagnosis of professional drivers' aptitude because of drivers' high tendency for positive self-presentation. However, they can be used in job

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

    Full Text Available Antecedentes: en Colombia, el alto recuento de células somáticas (RCS en la leche es un problema para la industria lechera. Altos recuentos pueden afectar de manera consi - derable los rendimientos y calidad final del queso. Varios países han establecido límites máximos estandarizados para el RCS. Colombia no lo ha hecho de manera oficial y tan solo unas pocas industrias manejan sus propios límites. Objetivos: Determinar el efecto del RCS sobre parámetros de aptitud quesera de la leche y la calidad sensorial del queso campesino. Métodos: Se tomaron muestras de leche de seis tanques con altos y bajos RCS y se realizaron mezclas para obtener 30 baches con diferentes RCS (desde 150.000 hasta 1.200.000 cel/ml. Con estas mezclas se elaboraron 30 quesos tipo campesino a los cuales se les determinaron variables de aptitud quesera (tiempo de coagulación, rendimientos y pérdidas en suero y la calidad organoléptica a través de una prueba sensorial descrip - tiva de puntajes con panel de seis jueces con experiencia previa y entrenados en queso campesino. Las variables de aptitud quesera fueron analizadas por regresión múltiple y los resultados de la evaluación sensorial con la prueba no paramétrica de Friedman. Resultados: La aptitud quesera disminuyó con RCS superiores a 200.000 cel/ml. El tiempo de coagulación (R 2 = 0.74; P < 0.001 y las pérdidas de proteína en el lactosuero (R 2 = 0.55; P <0,001 aumentaron, mientras que los rendimientos (R 2 =0.31; P <0.01 disminuyeron a medida que aumentó el RCS.

    Among the viticultural techniques developed to obtain wine with reduced alcohol content, the use of unripe grapes with low sugar and high malic acid concentration, harvested at cluster thinning, was recently explored. So far, no studies have evaluated the fermentation performances of Saccharomyces in unripe grape musts, in terms of fermentation ability and reducing malic acid contents, to improve the quality of this low-alcohol beverage. In this work, we evaluated 24 S. cerevisiae strains isolated from Italian and Croatian vineyards with different fermentation aptitudes. Moreover, four S. paradoxus were considered, as previous works demonstrated that strains belonging to this species were able to degrade high malic acid amounts in standard musts. The industrial strain S. cerevisiae 71B was added as reference. Sugar and malic acid contents were modified in synthetic musts in order to understand the effect of their concentrations on alcoholic fermentation and malic acid degradation. S. cerevisiae fermentation performances improved when glucose concentration decreased and malic acid level increased. The conditions that simulate unripe grape must, i.e. low glucose and high malic acid content were found to enhance S. cerevisiae ability to degrade malic acid. On the contrary, S. paradoxus strains were able to degrade high amounts of malic acid only in conditions that resemble ripe grape must, i.e. high glucose and low malic acid concentration. In fermentation trials when low glucose concentrations were used, at high malic acid levels S. cerevisiae strains produced higher glycerol than at low malic acid condition. Malic acid degradation ability, tested on the best performing S. cerevisiae strains, was enhanced in fermentation trials when unripe grape must was used.

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

    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 El cáncer de mama es el tumor más frecuente en las mujeres occidentales y afectará a una de cada ocho mujeres a lo largo de su vida. Su incidencia se ha incrementado pero la tasa de mortalidad ha descendido. El médico del trabajo debe valorar y adoptar las medidas de prevención adecuadas para atenuar los riesgos a los que puedan estar expuestos los trabajadores especialmente sensibles en el ámbito sanitario. Nuestro objetivo es proponer un método para esta valoración así como las adaptaciones necesarias para el desempeño de su tarea. Partimos de una revisión bibliográfica del cáncer de mama y se analizan los riesgos laborales del ámbito sanitario que pudieran suponer un agravamiento de las condiciones de salud de la trabajadora afectada. Exponemos un modelo de reconocimiento médico y valoración de la capacidad funcional adaptado a las secuelas más probables presentadas por las mujeres que han sido diagnosticadas de cáncer de mama, para proponer unos criterios de aptitud y recomendaciones de adecuación del puesto de trabajo.Breast cancer is the most frequent tumour in occidental women and it will affect one in eight women throughout their lives. Over the years, incidence rate has increased, whereas, mortality rate has decreased. The labour physician has to assess and decide on the suitable prevention measures to reduce those labour risks to which especially sensitive health workers may be exposed in their labour environment. Our objective is to propose a method for carrying out the assessment and the necessary adjustments for them to do their job. We begin with a bibliographic review about breast cancer to analyze the risks found in the health work environment that could worsen health conditions of the affected worker. We expose a model of medical examinations and assessment of the functional capacity, adapted to the most usual sequels shown up in women that have been diagnosed with breast cancer.

Metodología: Estudio descriptivo transversal realizado en 20 estudiantes (17,8 ± 1,33 años de sexo femenino de primer semestre, seleccionadas por conveniencia. Se recolectaron las variables edad, sexo, composición corporal, la flexibilidad de la musculatura posterior, la capacidad aeróbica y la resistencia muscular de miembros superiores y abdominales. Se calcularon medidas de tendencia central, de dispersión, frecuencias y porcentajes. Resultados: En promedio el peso fue de 52,8 ± 9,5 kg, la estatura de 1,58 ± 0,05 m, el IMC de 20,9 ± 3,5 kg/m2. La circunferencia de cintura y de cadera fue de 69,3 ± 9,2 cms y 91,3 ± 7,3 cm, respectivamente. El promedio del cuarto cuartil de las mediciones perímetro de cintura, perímetro de cadera, relación cintura-cadera, frecuencia cardiaca después de 30 s y distancia en la prueba de flexibilidad fueron estadísticamente mayores comparado con los demás cuartiles. El 50% de los pacientes realizó entre 0 y 3 repeticiones de la prueba Push-Up y entre 0 y 21 repeticiones en la prueba Cu rl-Up. El 65% fue físicamente apta hasta en cuatro pruebas y el 35% en 5 y 6 pruebas. Ninguna fue apta en todas las pruebas. Conclusiones: Dado que ninguna de las estudiantes posee una aptitud física relacionada con salud óptima, se sugiere que en los programas de fisioterapia se fomente una AFRS adecuada junto con estilos de vida saldables para prevenir enfermedades crónicas no transmisibles.

    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

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

    L'introduction des píeces miniatures dans le domaine de l'informatique et la microélectronique nécessite une grande précision et un environnement propre. D'autre part, la conservation d'énergie exige des pièces légères et une bonne longévité. Pour résoudre ces problèmes, des pièces autolubrifiées ont été proposées. En effet, plusieurs disciplines peuvent s'ingérer pour élaborer ces pièces: la métallurgie des poudres pour produire des pièces poreuses, la tribologie pour caractériser la pièce en fonctionnement et la mécanique des fluides pour évaluer le comportement échantillon -lubrifiant.
Dans ce présent travail, nous présentons l'évolution de la densité des échantillons élaborés en fonction de: la température d'élaboration, la pression de compactage, et le temps de maintien et l'évolution de l'absorption des lubrifiants par un alliage Cu-8% Sn fritté sous pression. Les lubrifiants choisis sont l'eau et une huile de machine à usage domestique et leur aptitude à l'autolubrification.

    In order to know the current mathematical aptitude situation of Chinese junior high school students, the mathematical aptitude test question for Japanese junior high school students in 2009 is used for testing a part of third-grade junior high school students in Jilin province, in this paper. The result shows that, average level of mathematical aptitude of junior high school students in our country is higher than Japanese. In addition, the polarity of ours is smaller than them. However, on expression and processing of mathematics, our students are weak than Japanese. Some of Chinese junior high school students, whose understanding on depth and breadth of some mathematical concepts, principles and rules are not enough. Furthermore, our ability on flexible use of knowledge and skills are poor. Therefore, Mathematical education in China should focus on basic mathematical concepts, principles and rules. Moreover, training of mathematical communication skills, and establishing a correct and comprehensive view of the mathematical aptitude should be seriously focused.%运用日本2009年初中数学学力测试题,对吉林省部分初中三年级学生进行测试,以了解中国初中生数学学力的现状.结果表明:中国初中生数学学力的平均水平高于日本,但在“数学地表达和处理问题”方面,中国学生不如日本.中国部分初中生对某些数学概念、原理和法则理解的深度和广度不够,在知识和技能灵活运用方面欠佳.因此,中国初中数学教学应重视学生对基本数学概念、原理和法则的理解;重视培养学生的数学交流能力;重视学生全面学力的培养.

    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

    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

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

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.

Se tomaron muestras de suelos, a tres profundidades, en 62 sitios; a las cuales se les midió pH, materia orgánica (MO, fósforo (P, textura e hierro (Fe. 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.

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

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.

    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.

    The main challenges faced by the current National College Entrance Examination(NCEE)system are following:college’s autonomy of enrolling new students and examinee’s vocational aptitude are ignored, and only one testing opportunity is a bit on chance. In order to solve these problems, the highly uniform model of setting examinational subjects and weights in NCEE system must be reformed, and examinee’s individual differences in abilities in different subjects and college’s admission requirements in different majors must be highly valued. Under the uniform framework of NCEE, examinational subjects are suggested to be classified as obligatory and optional subjects. The obligatory subjects and weight ranges of all obligatory and optional subjects are nationally uniform. The optional subjects and individual weights of all obligatory and optional subjects in every college major are set by colleges and universities. All examinees are free to choose optional subjects and corresponding college majors. After raw scores are linearly transformed into standard scores, scores of every examinational subject in every college major are added together by its weight to get total scores. New students are enrolled based on the sequence of total scores in every college major and the sequence of every examinee’s choices for college majors. What is crucial in the new wave of NCEE reform is following: in the light of balancing uniformity and variability in the NCEE, examinee’s vocational aptitudes are measured by means of setting examinational subjects and their weights, examinees can choose college majors favorable for their vocational aptitudes based on advantages in abilities of examinational subjects, colleges and universities can enroll new students of corresponding vocational aptitudes based on characteristics of college majors.%当前高考制度面临着高校招生自主权难以落实、考生专业性向未受重视、一次考试机会偶然性大等主要问题。

    Full Text Available Com o envelhecimento verifica-se uma progressiva deterioração da marcha, sendo múltiplos os fatores de risco que podem contribuir para as quedas. As quedas são um problema de saúde pública com consequências médicas e económicas significativas. Este estudo teve o objetivo de avaliar a relação entre a aptidão física/atividade física e estabilidade postural na incidência de quedas em idosos. Método: estudo transversal, descritivo e comparativo com 49 idosos institucionalizados e 63 idosos não-institucionalizados. Utilizou-se o Functional Fitness Test, Functional Reach Test, MOS-SF-36 e o questionário de Baecke para avaliar a aptidão física e funcional, estabilidade postural, qualidade de vida e níveis de atividade física, respetivamente. Resultados: os idosos não-institucionalizados possuem melhor aptidão física, nomeadamente força, resistência aeróbia e agilidade/equilíbrio dinâmico, índices mais elevados de atividade física e qualidade de vida. Observaram-se correlações significativas entre os desempenhos nos testes de aptidão física e os índices de agilidade/equilíbrio dinâmico e estabilidade postural. Conclusão: a diminuição da aptidão física com o envelhecimento e os baixos níveis de atividade física contribuem para défices funcionais e de estabilidade postural que podem originar quedas.Con el envejecimiento se produce un deterioro progresivo de la marcha, con múltiples factores de riesgo que pueden contribuir a las caídas.

    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.

OBJETIVO: Realizar teste cardiopulmonar (TCP em hemiparéticos para uma avaliação pré-participação visando uma criteriosa prescrição de exercício aeróbico. MÉTODOS: Participaram do estudo 8 indivíduos com hemiparesia crônica, que foram submetidos a TCP realizado com protocolo individualizado em rampa, desenvolvido a partir da informação da velocidade de marcha dos indivíduos previamente avaliados em teste de pista. Foi considerada a proposta de inclinação variando entre 0 e 10,0%, velocidade inicial correspondente a 70,0% do ritmo de caminhada confortável e velocidade máxima 40,0% superior à velocidade máxima no teste de pista, na expectativa de que o TCP, com este incremento gradativo e constante da intensidade, durasse entre 6 e 8 minutos. RESULTADOS: Em 100,0% dos avaliados, o motivo para a interrupção do teste foi fadiga periférica. O VO2 de pico alcançado foi de 20,6 ± 5,7 ml/kg.min. O Limiar I foi identificado em todos os exames, situando-se em 82,64 ± 4,78% da FC de pico e 73,31 ± 4,97% do VO2 de pico. O quociente respiratório (R do grupo foi de 0,96 ± 0,09, e três dos 8 indivíduos (37,5% atingiram R superior a 1,00, sendo o Limiar II identificado nestes sujeitos. Foram encontradas relações positivas entre variáveis do TCP e escores de equilíbrio, desempenho no teste de caminhada de 6 minutos e velocidade de marcha no solo. CONCLUSÃO: O teste mostrou ser útil para prescrição de atividade física nesses indivíduos.FUNDAMENTO: Debido a la hemiparesia, la evaluación de la aptitud cardiorrespiratoria de individuos después de accidente vascular encefálico (AVE, por medio de pruebas ergométricas con protocolos convencionales, se ha vuelto en un reto.

    Mental rotation ability (MRA) is linked to academic success in the spatially complex Science, Technology, Engineering, Medicine, and Mathematics (STEMM) disciplines, and anatomical sciences. Mental rotation literature suggests that MRA may manifest in the movement of the eyes. Quantification of eye movement data may serve to distinguish MRA across individuals, and serve as a consideration when designing visualizations for instruction. It is hypothesized that high-MRA individuals will demonstrate fewer eye fixations, conduct shorter average fixation durations (AFD), and demonstrate shorter response times, than low-MRA individuals. Additionally, individuals with different levels of MRA will attend to different features of the block-figures presented in the electronic mental rotations test (EMRT). All participants (n = 23) completed the EMRT while metrics of eye movement were collected. The test required participants view pairs of three-dimensional (3D) shapes, and identify if the pair is rotated but identical, or two different structures. Temporal analysis revealed no significant correlations between response time, average fixation durations, or number of fixations and mental rotation ability. Further analysis of within-participant variability yielded a significant correlation for response time variability, but no correlation between AFD variability and variability in the number of fixations. Additional analysis of salience revealed that during problem solving, individuals of differing MRA attended to different features of the block images; suggesting that eye movements directed at salient features may contribute to differences in mental rotations ability, and may ultimately serve to predict success in anatomy.

    Full Text Available Sports cognition encompasses the primary affective-motivational aspect related to primordial fight-or flight responses, which are essentially the precursors for both the BAS (behavioural activation system - the reward system and BIS (behavioural inhibition system- the punishment or fear-eliciting system. In Asian and especially South-Asian perspective, impulsivity and aggressive out-bursts are by and large considered as conduct disorders, thus more acceptable docile tendency in children and pre-adolescent lead them to a cognitive-motivational make-up of BIS orientation. With such a background the present study was carried out to identify the extent of cognitive-affective competence of the skilled competitive players in enhancing bilateral motor coordination required for high sport performance. Eighty-one high performing female ball game players matched with their performance-specific motor coordination ability, were categorised into three differential groups based on their psychobiological competence, viz; Group A- consisted of twenty-seven players diagnosed with moderate level of sympathovagal balance; Group B (N = 27 – consisted of twenty-seven players diagnosed with discordant sympathovagal balance, while Group C (n = 27 were identified as having high sympathovagal balance. Thereafter, players of Group B & C were introduced to training of skin-conductance biofeedback tailored for musculoskeletal enhancement (20 min.s/ day; three days/ week for twelve weeks. Mid-term analyses of motor coordination as well as the post-intervention analyses (carried out after the twelfth week revealed that players having higher sympathovagal balance had higher efficiency in modulation of muscle tension as well as in perceptual –motor adaptation, which have prompted them to have enhanced bilateral and visual-motor coordination compared to their counterparts.

    Since the introduction of the Basic Safety Standards recommendations, the scope of the radiation protection was broadening. On behalf of the incorporation of radiation protection of the patient in medical exposures, the different groups of professionals involved: physicians, medical physicists, radiation protection officers, regulators, etc., have to work together. The objective of radiation protection, that is, to reduces doses from practices, to prevent potential exposures, to detect its occurrence as well as to evaluate and spread such abnormal situations, will be obtained only if it were possible to joint two basic conditions: knowledge and attitude. It should be well known the differences between the backgrounds needed to be for example, a medical physicist or an R.P.O., However, their attitude to solve an eventual problem involving radiation protection should be the same; as well as the behavior of the specialized physician and regulators, in order to add towards common goals. In this work, we show as an example the curricula contents about radiation protection of the cancer of medical physics in the Universidad Nacional de San Martin (UNSAM), and the corresponding module on medical exposures from the Post-Graduate course on Radiation Protection and Nuclear Safety, held since the 80s in Buenos Aires by the National Commission of Atomic Energy, ARN, IAEA, and the Universidad de Buenos Aires. On the other hand, we describe different attitudes which leads or could start major radiological accidents, regardless the level of knowledge in radiation protection. We conclude that the larger numbers of accidents are due to problems in the attitude than in the level of knowledge of the person involved. Consequently; we suggest emphasizing the discussion on how to generate positive attitudes in every professional involucrated, independently of its cognitive profile or level. (Author) 2 refs.

    Full Text Available A database was created using the yield values and the soil characteristics from more than 50 field experiments, and from other areas that belonged to good producers in Cienfuegos. All the experiments were done on brown carbonated, brown non-carbonated and red ferralitic soils. The soils characteristics were selected based on a varied analysis of main components and taking the easily-determined variables. For each soil characteristic that was selected, a classification system was established, that encompasses several variable ranges, the category assigned to each range, and a point value for each category. This classification system was based on articles reviews, and also taking into account the results of many researchers. A linear regression analysis was done using sugarcane yield and the values of soils where the sugar cane was planted and the cases of “excellent management” and “adequate management” of the cultivar was discriminated. It was proved that the soil value and the sugarcane yield were highly related (linear regression, which made possible the elaboration of a table that relates the sugarcane productive potential according to the characteristics of the soil expressed by the accumulated points, depending on the quality of the cultivar management and the agricultural cycle (plant cane or ratoon.

    A joint COGEMA/CEA action aims at evaluating the conditions allowing the extension beyond 50 years of the exploitation of the E/EV/SE vitrified wastes storage facility of the UP3 factory of La Hague (France). The approach considered consists in analysing the technical and administrative aspects of the facility in order to determine the changes to be implemented for its qualification as very long storage facility. Three target characteristics have been identified as priorities for this analysis: safety, civil engineering, and cooling ventilation of wells, and thus three working groups have been created. According to works carried out, facilities like the E/EV/SE one are designed in such a way that their durability can reach the century scale: the robustness of the cooling process, the passiveness of most equipments and the limitation of components functions are the main strong points. Service life limitations come mainly from the thermal evolution of waste packages and the aging of components under the climate conditions: risk of atmospheric corrosion of the bottom part of wells under the effect of water condensation, and risk of corrosion of concrete reinforcements. Suggestions of improvement of the quantification and understanding of phenomena influencing the lifetime limitation are made, and some possible technical solutions are proposed. (J.S.)

    Full Text Available This research analyzes different memory types -muscular, visual, auditive..- and the strategies followed by a group of 10 piano students from the first year of “Conservatorio Profesional” (5th year of studies when memorizing an unfamiliar score depending on three conditions: in the first one the students may use the piano (physical practice; in the second one they may not use the piano (mental practice with listening but have an audio recording of the score, and in the third one, they have no piano and no recording (mental practice without listening. The memorization phase (30’, the performance by heart of the score (1’-2’ and a short interview of the student are video-recorded to evaluate the performance and the memorizing processes. The outcome of the performance is analyzed as a function of the students preexisting skills (piano and musical language, of the behavior and attitude variables and of the memorization phase processes. The results show that the performance quality depends significantly on the access to the piano during the memorization (p<0.01 and, to a lesser extent, to the audio recording. This shows the importance of muscular and also auditory memory, corroborating the results in the literature. The preexisting skills of the participants, in particular note-reading skills (p<0.01 and piano technique (p<0.05 influence the performance quality, while the different memorizing strategies used have no significant correlation with the performance or the skills, contrarily to our expectations. Keywords: music memory types, music memory strategies, musical performance, piano.

  7. Is the aptitude of manual skills enough for assessing the training effect of students using a laparoscopy simulator?

    Directory of Open Access Journals (Sweden)

    Zielke, Andreas

    2005-12-01

    Full Text Available Background: The aim of this study was to determine if students are suitable candidates to assess the learning effect through a virtual reality laparoscopy simulator (LapSim®. Materials and methods: 14 medical students in their final year without any previous experience with a virtual reality simulator were recruited as subjects. In order to establish a "base line" all subjects were instructed into the "clip application" task - a basis module of the laparoscopy simulator - at the beginning of the study. They were then randomized into two groups. Group A (n=7 had parameter adjusted to an easy level of performance, while group B (n=7 was adjusted to a difficult level. In both levels, errors simulated clinically relevant situations such as vessel rupture and subsequent bleeding. Each participant had to repeat the clip application task ten times consecutively. Results: The mean time for completion ten repetitions was 15 min pro participant in group A and 20 min in group B. From the first to the fifth repetition group A improved significantly the task completion time from 238.9 s to 103.3 s (p<0.007 consecutively and also improved the error score from 312 to 177 (p<0.07. At the tenth repetition they increased the task completion time from 103.3 s to 152.2 s (p<0.09 and increased their error score from 177 to 202 (p=0.25. From the first to the fifth repetition group B also improved the task completion time from 131.6 s to 104.5 s (p<0.31 consecutively and improved the error score from 235 to 208 (p<0.32 but at the tenth repetition they increased the task completion time from 104.5 s to 142.4 s (p<0.45 and clearly increased their error score from 208 to 244 (p<0.38. Conclusion: These results suggest that medical students, who lack clinical background, may be not suitable candidates for assessing the efficiency of a training model using a laparoscopy simulator. If medical students are appointed for such studies, they should receive didactic sessions in the context of a clinical curriculum prior to manual training.

  8. Instructional design in a chemistry laboratory course: The impact of structure and aptitudes on performance and attitudes

    Science.gov (United States)

    Kozma, Robert B.

    Elements of instructional design such as explicitly stated objectives, reviews, examples, questions, and feedback were incorporated into the laboratory manual and instruction for a unit on kinetics in a college laboratory course. This treatment (high structure) was given to five sections of students (N = 109), while a laboratory manual and instructions that emphasized informational content without the use of these design strategies (low structure) was given to another five sections (N = 108) taught by the same instructors. The students receiving the additional structure scored significantly higher on a quiz, took less time to solve a set of laboratory problems, and felt more satisfied with the instruction provided. There were no differences between groups in their comfort with the knowledge acquired. There were no interactions with performance outcomes, but several occurred for attitudes, treatments, and personality measures. The more conforming the students, the more satisfied they were with the instruction in the high-structured group and the less they liked it in the low-structured group. The more motivated the students, the more they liked the instruction in the high-structure treatment, and even more in the low-structure group. There was also a complex interaction among treatment, anxiety, ability, and treatment satisfaction.

    2012-03-01

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

    An unanswered question in adult language learning or late bi and multilingualism is why individuals show marked differences in their ability to imitate foreign accents. While recent research acknowledges that more adults than previously assumed can still acquire a "native" foreign accent, very little is known about the neuro-cognitive correlates of this special ability. We investigated 140 German-speaking individuals displaying varying degrees of "mimicking" capacity, based on natural language text, sentence, and word imitations either in their second language English or in Hindi and Tamil, languages they had never been exposed to. The large subject pool was strictly controlled for previous language experience prior to magnetic resonance imaging. The late-onset (around 10 years) bilinguals showed significant individual differences as to how they employed their left-hemisphere speech areas: higher hemodynamic activation in a distinct fronto-parietal network accompanied low ability, while high ability paralleled enhanced gray matter volume in these areas concomitant with decreased hemodynamic responses. Finally and unexpectedly, males were found to be more talented foreign speech mimics.

    2013-01-01

    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 in der Zahnmedizin. Durch den Einsatz des HAM-Nat wird die Vorhersage des vorklinischen, akademischen Studienerfolgs in der Zahnmedizin deutlich verbessert.

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

    Science.gov (United States)

    Kadmon, Guni; Kadmon, Martina

    2016-01-01

    Hintergrund: Die Auswahl Medizinstudierender wird in Deutschland teils zentral, teils lokal durchgeführt. Die zentrale Auswahl umfasst zwei Gruppen: Studierende mit den besten Hochschulzulassungsnoten (Abiturbeste) und Studierende mit schlechteren Abiturnoten, die erst nach einer Wartezeit von bis zu sieben Jahren nach Schulabschluss zum Studium zugelassen werden (Wartezeitquote). Studierende mit Lernschwierigkeiten sowie solche, die das Studium frühzeitig abbrechen, befinden sich in beiden Gruppen. Die hochschuleigene Studierendenauswahl (AdH) unserer Fakultät berücksichtigt das Ergebnis des Tests für Medizinische Studiengänge (TMS) und ermöglicht die leistungsbezogene Zulassung von Studierenden mit einer breiten Spannweite an Abiturnoten. Ziel: Zu untersuchen, ob die Gewichtung des TMS in der hochschuleigenen Auswahl gerechtfertigt ist, die darauf abzielt, die Zulassung potentiell leistungsschwacher Abiturbesten zu reduzieren und stattdessen die Zulassung potentiell leistungsstarker Bewerber zu fördern, die mittelmäßige Schulabgangsnoten mitbringen.Methode: Der prognostische Beitrag der Abiturpunktzahl und des TMS zur Studienleistung und zur Studienkontinuität im vorklinischen Abschnitt des Medizinstudiums wurde an zwei Studierendengruppen untersucht: Abiturbeste (Abiturnote 1,0, Abiturpunkte 823-900) und mittelmäßige Abiturienten (Abiturnoten 2,0-2,3, Abiturpunkte 689-660). Das Outcome beider Gruppen wurde im Verhältnis zu ihren TMS-Ergebnissen verglichen. Die Studie umfasste vier aufeinander folgende Kohorten. Ergebnisse: In beiden Gruppen sagte der TMS die Studienleistung (β=0,442-0,446) und die Studienkontinuität (OR=0,890-0,853) besser vorher als die Abiturnote (β=0,238-0,047; OR=1,009-0,998). Die Studienverlängerungs- und -abbruchsrate war am stärksten mit der Nicht-Teilnahme am TMS assoziiert (OR=0,230-0,380). Studierende mit mittelmäßigen Abiturnoten und TMS-Ergebnissen (standardisiertem Testwert) ≥125 erzielten ähnlich gute Studienleistungen wie die Abiturbesten. Mittelmäßige Schulabgänger mit TMS-Ergebnissen zwischen 110-124 erbrachten im Schnitt weniger gute aber noch ausreichende Studienleistungen. Abiturbeste mit mittelmäßigen TMS-Ergebnissen und 30% der Abiturbesten, die nicht am TMS teilgenommen hatten, erreichten nicht das Studienleistungsniveau der meisten Studierenden mit mittelmäßigen Abiturnoten und sehr guten TMS-Leistungen. Diskussion: Der TMS scheint, zwischen potenziell erfolgreichen und weniger erfolgreichen Studierenden beider Abiturnotenbereiche zu differenzieren. Mittelmäßige Abiturienten mit besonders hohen TMS-Ergebnissen erreichten bessere Studienergebnisse im vorklinischen Studienabschnitt als die Abiturbesten, die im TMS nur mittelmäßigen Erfolg hatten. Diese Beobachtungen rechtfertigen die Anwendung des TMS, um die Chancen von Studienbewerbern mit mittelmäßigen Abiturnoten am Wettbewerb um die Studienplätze zu erhöhen.

    Independently of the theoretical study of the propagation of radioactivity in the soil as a result of submersions or of radioactive rain, the authors have studied directly and practically how this radioactivity can vary in the actual soil. To this end a simple, rapid method has been perfected; it makes it possible to maintain for each soil sample the natural parameters (structure, humidity, etc.) without introducing boundary effects. In the laboratory, after charging the soil samples, part of the study of the propagation of radioactivity is done by autoradiography; finally, as a practical application, the study of an atomic site illustrates the methods described.

En laboratoire, apres mise en charge des massifs preleves, une partie de l'etude de la propagation des radioelements est realisee par autoradiographie; enfin, une application pratique, l'etude d'un site atomique, illustre l'expose.

    Full Text Available Siendo como es gran parte de la actividad de los médicos evaluadores del INSS íntimamente relacionada o incluso fundamentada en la relación entre el trabajador en activo y sus condiciones de trabajo generales y particulares resulta llamativa la ausencia de un mecanismo normalizado de comunicación con los especialistas en Medicina del Trabajo de los Servicios de Prevención cuyo objeto de actuación son precisamente los trabajadores y sus condiciones laborales. Se defiende que aquellos agentes de la medicina evaluadora, preventiva o asistencial que intervienen en la toma de decisiones sobre el estado psico-físico de una persona y las condiciones laborales, deberían disponer de toda la información necesaria de ambas para que sus resoluciones sean ajustadas a la realidad y por tanto más justas. El Médico del Trabajo del Servicio de Prevención es el especialista que dispone de la información sobre las condiciones laborales y quien mejor sabe interpretarlas. La información sobre las mismas debería de partir desde el Médico del Trabajo hacia el resto de los agentes. Se presentan algunas experiencias dirigidas a normalizar el flujo de información sobre condiciones laborales y estado de salud entre los diferentes interlocutores. Partiendo del principio de que la salud del individuo es única y está conformada por todo aquello que le afecta, tanto en su actividad profesional como en su vida extralaboral en un complejo juego de interrelaciones que se influyen y modifican de forma dinámica y continua, se plantea el interés por el desarrollo de una historia clínica única, compartida en aspectos considerados básicos y que permita una comunicación rápida, eficiente y dinámica entre todos los agentes que intervienen en la salud de un trabajador, aunque en la actualidad resulte una quimera. De camino hacia ese objetivo, se evidencia la necesidad previa de elaboración de un modelo de Historia Clínico-Laboral Única y se describen algunas acciones encaminadas hacia este objetivo.

  13. Synthesis and coordination chemistry of two N2-donor chelating di(indazolyl)methane ligands: structural characterization and comparison of their metal chelation aptitudes.

    Science.gov (United States)

    Pettinari, Claudio; Marinelli, Alessandro; Marchetti, Fabio; Ngoune, Jean; Galindo, Agustín; Álvarez, Eleuterio; Gómez, Margarita

    2010-11-15

    The N(2)-donor bidentate ligands di(1H-indazol-1-yl)methane (L(1)) and di(2H-indazol-2-yl)methane (L(2)) (L in general) have been synthesized, and their coordination behavior toward Zn(II), Cd(II), and Hg(II) salts has been studied. Reaction of L(1) and L(2) with ZnX(2) (X = Cl, Br, or I) yields [ZnX(2)L] species (1-6), that, in the solid state, show a tetrahedral structure with dihapto ligand coordination via the pyrazolyl arms. The reaction of L(1) and L(2) with Zn(NO(3))(2)·6H(2)O is strongly dependent on the reaction conditions and on the ligand employed. Reaction of L(1) with equimolar quantities of Zn(NO(3))(2)·6H(2)O yields the neutral six-coordinate species [Zn(NO(3))(2)(L(1))], 7. On the other hand the use of L(1) excess gives the 2:1 adduct [Zn(NO(3))(2)(L(1))(2)], 8 where both nitrates act as a unidentate coordinating ligand. Analogous stoichiometry is found in the compound obtained from the reaction of L(2) with Zn(NO(3))(2)·6H(2)O which gives the ionic [Zn(NO(3))(L(2))(2)](NO(3)), 10. Complete displacement of both nitrates from the zinc coordination sphere is observed when the reaction between L(1) excess and the zinc salt was carried out in hydrothermal conditions. The metal ion type is also determining structure and stoichiometry: the reaction of L(2) with CdCl(2) gave the 2:1 adduct [CdCl(2)(L(2))(2)] 11 where both chlorides complete the coordination sphere of the six-coordinate cadmium center; on the other hand from the reaction of L(1) with CdBr(2) the polynuclear [CdBr(2)(L(1))](n) 12 is obtained, the Br(-) anion acting as bridging ligands in a six-coordinate cadmium coordination environment. The reaction of L(1) and L(2) with HgX(2) (X = Cl, I, SCN) is also dependent on the reaction conditions and the nature of X, two different types of adducts being formed [HgX(L)] (14: L = L(1), 16, 17: L = L(1) or L(2), X = I, 19: L = L(2), X = SCN) and [HgX(L)(2)] (15: L = L(2), X = Cl, 18: L = L(1), X = SCN). The X-ray diffraction analyses of compounds 1, 2, 4, 5, 7, 8, 10-12, 14, 15, and 19 are also reported. The variations of the coordination geometry parameters in the complexes are compared and discussed.

  14. Aptitude of Lymnaea palustris and L. stagnalis to Fasciola hepatica larval development through the infection of several successive generations of 4-mm-high snails.

    Science.gov (United States)

    Vignoles, P; Rondelaud, D; Dreyfuss, G

    2016-06-01

    Bimiracidial infections of Lymnaea palustris and Lymnaea stagnalis (shell height at exposure, 4 mm) with Fasciola hepatica were carried out during six successive snail generations to determine if prevalence and intensity of snail infection increased over time through descendants issuing from eggs laid by parents already exposed to this digenean. Controls were constituted by a French population of Galba truncatula (a single generation) infected according to the same protocol. In a first experiment performed with the F1 to F5 generations of L. palustris, the prevalence and intensity of F. hepatica infection in snails progressively increased. Immature rediae and a few cercariae-containing rediae of the digenean were observed in L. stagnalis from the F3 generation, but no free cercaria was noted in the bodies of this lymnaeid from the F4 to F6 generations. In another experiment carried out with the F6 generation of L. palustris, the prevalence of F. hepatica infection and the number of shed cercariae were significantly lower in L. palustris than in G. truncatula. This mode of snail infection suggests an explanation for cases of human fasciolosis occurring in central France after the collection of wild watercress from beds where L. palustris was the sole lymnaeid.

    Full Text Available Nowadays it has been demonstrated that the stimulation of the child during these stages constitutes a crucial process in his evolution, in the biological, psychological and social aspects. As the child grows so do his abilities, and therefore a clear need to keep them in constant interaction and potential for their further development lead in an adequate adaptation to situations he must face. For that reason it is a need that is not the mere whim of a society that is constantly evolving, it is a reality that has been working ever since and its results have been t both quantitatively and qualitatively. Numerous studies show that non stimulated children have lower academic performance in relation to those who have received an adequate stimulation. However, alarming data has been found showing lack of stimulation in children of these ages, this fact can cause a delay in any development areas. For the development of certain cognitive elements and maturity in children, it is necessary to provide them opportunities to potentiate their abilities and skills so that they can achieve a healthy development and the formation of higher cognitive processes, as well as the reach of goals.ResumenHoy día es evidente que la estimulación del niño constituye un proceso crucial para su evolución en las dimensiones biológica, psicológica y social. A medida que avanza el crecimiento del niño lo hacen también sus capacidades, y por lo tanto resulta imprescindible mantenerlasen constante interacción y estimular su potencialidad para que su desarrollo conlleve en lo posterior una adecuada adaptación a situaciones que deberá enfrentar. Se trata así de una necesidadque trasciende el simple capricho de una sociedad en constante evolución. Numerosas investigaciones han demostrado que los niños no estimulados tienen menores rendimientos escolares en relación con aquellos que han recibido una adecuada estimulación. No obstanteello, se han encontrado datos alarmantes que demuestran la falta de la misma en la infancia temprana, lo cual puede condicionar un retraso en cualquiera de las áreas de desarrollo.

    Full Text Available En este artículo se plantea una estrategia de compensación de reactivos paralelo con capacitores, para aumentar la capacidad del campo de prueba de cortocircuito de la Universidad del Valle. Los transformadores son elementos esenciales para mantener el suministro de energía eléctrica. Por esta razón deben tener una capacidad adecuada para soportar las exigencias mecánicas, térmicas y eléctricas que se presentan durante un cortocircuito. En el laboratorio de ensayos de Alta Tensión de la Universidad del Valle (Cali. Colombia, se cuenta con un campo de prueba de cortocircuito para transformadores de distribución, el cual tiene capacidad de probar transformadores monofásicos hasta 100kVA y trifásicos hasta 300kVA. Este campo está limitado por la capacidad de corriente en la red y la prueba sólo se puede hacer a un voltaje fijo, definido por el circuito de alimentación. Los resultados muestran que la compensación paralela es una alternativa viable para reducir los requerimientos de capacidad de corriente de un campo de pruebas de cortocircuito.This article presents a strategy for using parallel reactive compensation with capacitors to increase the capacity of the short circuit test field at the Universidad del Valle. Transformers are key elements to maintain the electrical supply service. For that reason they must have an adequate capacity to withstand the mechanical, thermal and electrical stresses that occur during a short circuit. The High Voltage testing laboratory of the Universidad del Valle ( Cali, Colombia , carries out short circuit tests for single phase distribution transformers up to 100kVA and for three phase transformers up to 300kVA . The short circuit withstand test at the laboratory is limited by the distribution network current capacity and the test can only be done at a fixed voltage , defined by the electrical network. The results show that parallel reactive compensation is a good alternative to reduce capacity requirements in short circuit tests.

    Robert Plante

    2010-02-01

    Full Text Available Au Québec, en santé au travail, l’approche de santé publique a été privilégiée à l’approche médicale individuelle, parce qu’elle est conséquente aux objectifs de la loi, à savoir la prise en charge par le milieu de ses problèmes et la diminution, voire l’élimination des dangers. Quant aux activités médicales individuelles, elles ne sont réalisées que lorsqu’elles sont légitimes, c’est-à-dire lorsque leur pertinence et leur efficacité sur le plan de la prévention ont été démontrées. Quelques évaluations l’ont confirmé, l’approche par programme des services de santé publique québécois fonctionne en général très bien et elle est efficace. Mieux que l’examen médical de chaque sujet, elle permet de centrer les énergies sur les expositions professionnelles et les composantes de l’organisation du travail susceptibles de provoquer des problèmes. Malgré toutes ses qualités, le système de santé au travail québécois se heurte à de sérieuses résistances institutionnelles et politiques qui ont compromis son développement et mènent progressivement à son essoufflement.In Québec, in occupational health, the public health approach has been favoured over the individual medical approach because it is consistent with the objectives of the law, namely this community taking charge of its problems, and the reduction and even elimination of risk factors. Individual medical activities are limited to cases where the relevance and effectiveness of preventive benefits have been demonstrated. Some evaluative studies have shown that this Québec public health program approach works well in general, and is effective. Compared with the medical examination of each subject, it has a better potential for focusing energies on occupational exposures and on work organizational factors that could cause problems. Despite all its advantages, the Québec occupational health system is facing serious institutional and political resistance that has compromised its development and is gradually leading it to its dysfunction.En Quebec, en salud laboral, el enfoque de salud pública ha favorecido el enfoque médico individual, porque éste es consecuente con los objetivos de la Ley, a saberse : la asunción por parte del medio de sus problemas y la disminución o eliminación de los riesgos. En cuanto a las actividades médicas individuales, estas no son realizadas sino una vez que son legitimas, le que quiere decir que se realizan cuando es demostrada su pertinencia y eficacia en el plano de la prevención. Algunas evaluaciones han confirmado que el enfoque por programa de servicios de salud pública en Quebec funciona muy bien y es eficaz. Mejor que el examen médico individual, este programa permite concentrar las energías en las exposiciones profesionales y en los componentes de la organización de trabajo que podrían provocar problemas. A pesar de todas sus cualidades, el sistema de salud laboral de Quebec, afronta serias oposiciones institucionales y políticas que han comprometido su desarrollo y conducen progresivamente a su estancamiento.

  4. [The training of specialists at the Instituto Mexicano de Seguro Social. Towards a new evaluation system].

    Science.gov (United States)

    Viniegra Velázquez, Leonardo

    2005-01-01

    We present the new system for the evaluation of the medical specialization courses at the IMSS which will substitute in 2005 the one used at present. This system derives from a participative conception of education and has as an axis the development of aptitudes. For participative education, knowledge is the result of the student's elaboration, and not the result of the consumption of information. An aptitude is the conjunction of knowledge, abilities and attitudes in a constant development which gives the bearer experience a growing penetration to understand the problematic situations that challenge him, a greater reach of the decisions and actions performed and progressive pertinence to positively influence the working environment. The new evaluation system is centered in the development of two types of aptitude: the clinical aptitude and the aptitude for the appropriate use of information sources. It has an explanatory and instructions section, as well as four types of forms: (a) evaluation of the aptitudes development through time. (b) Performance of activities (in the service and academic) related with the aptitudes seeking to develop. (c) Evaluation of the academic and working environment, and (d) self evaluation. With the new system of evaluation of the formation of medical specialists we pretend to contribute to the overcoming of the educative labors at the Institute, by orienting the professors' and students' reflection towards the main aspects of learning, as well as promote the criticism and self-criticism.

    Full Text Available Resumen. El agotamiento de las reservas petrolíferas y la creciente demanda energética mundial, ponen en evidencia la necesidad de ampliar la oferta de aceites para la producción de biodiesel. El objetivo principal de este estudio, fue determinar las zonas aptas con diferentes aptitudes agroecológicas, para establecer el cultivo de Jatropha curcas en el estado de Tabasco. Para ello se definieron cuatro tipos de aptitud: óptima, adecuada, marginal por déficit térmico e hídrico, y marginal por exceso térmico e hídrico. Para el recurso suelo se consideró la fertilidad, profundidad, textura y pH, y se utilizó la clase de aptitud óptima. La delimitación de estas zonas se generó mediante la implementación de un sistema de información geográfica (SIG, el cual facilitó la manipulación y sobreposición de capas de información temática de clima y suelo. El análisis promedio anual de temperatura demostró que todo el estado de Tabasco presenta aptitud óptima y con el de precipitación se obtuvo una superficie de 2 229 631 ha con aptitud óptima. En lo referente al recurso suelo se detectaron 37 subunidades de suelo con aptitud óptima, sumando una superficie de 945 462 ha. Al realizar el álgebra de mapas entre las aptitudes óptimas climáticas (temperatura, precipitación y periodo de crecimiento y edafológicas, se obtuvieron 833 181 ha con aptitud agroecológica óptima, por lo que en el estado de Tabasco es factible cultivar esta oleaginosa para producir biocombustibles.

Se evaluó la aptitud relativa agrícola, mediante la modificación del modelo Almagra del sistema MicroLEIS 4.1, el cual permite definir la aptitud relativa agrícola, de lo cual resulta el Almagra-Tuxpan, al crearse una base de datos con las condiciones específicas de esta región. Con base en el modelo Almagra-Tuxpan se determinó la aptitud relativa agrícola para cada una de las unidades de mapeo de suelos y se evaluaron los niveles de aptitud de 12 cultivos tradicionales (fríjol, sorgo, maíz, tabacos (Virginia y Burley, chile, jitomate, melón, sandía, jícama, cacahuate y algodón. El 21.73% presenta una aptitud buena para la mayoría de los cultivos evaluados, el 59.98%, una aptitud moderada y el 18.43% nula capacidad. En general excluyendo las unidades de aptitud nula, los suelos de este municipio tienen una aptitud para algodón, maíz y sorgo. Los dos últimos se cultivan intensamente y el primero sería una alternativa para la región.

No entanto, estudos comparando estes parâmetros e sua possível aplicação para indivíduos não atletas ainda não foram realizados. Os objetivos do presente estudo foram comparar e estabelecer as relações entre IAT, IGT, Vmax, Vm3km e VC em indivíduos fisicamente ativos não atletas. Onze indivíduos fisicamente ativos e saudáveis (20,7 ± 1,8 anos; 74,2 ± 14,5kg; 48,9 ± 5,8mlO2.kg.min-1 realizaram randomicamente os seguintes testes de corrida em dias distintos: 1 determinação da Vm3km a partir do desempenho em corrida de 3.000m; 2 desempenho em corrida de 500m e 3 teste incremental em esteira ergométrica para determinação do IAT, IGT, VO2max e Vmax. A VC foi determinada por regressão linear (relação distância-tempo a partir dos testes de 3km e 500m. Não foram verificadas diferenças entre as velocidades do IAT e IGT (184,8 ± 27,7 e 182,8 ± 27,9m.min-1; P > 0,05, e entre Vmax e Vm3km (211,1 ± 30 e 213,4 ± 32,2m.min-1; P > 0,05.

However, a comparison of these variables and their usefulness for physically active non-athletes individuals were not investigated yet. The objectives of this study were to compare and to verify the relationship between Vmax, Vm3km, CV, IAT and IGT in physically active non-athlete individuals. Eleven healthy and physically active individuals (20.7 ± 1.8 yr., 74.2 ± 14.5 kg, 48.9 ± 5.8 mlO2.kg.min-1, randomly accomplished to the following running tests on different days: 1 3,000 m performance for Vm3km; 2 an all-out 500 m running track and 3 an incremental treadmill test for IAT, IGT, VO2max and Vmax determination. The CV was determined by linear regression (distance-time relation by using the 3,000 m and 500 m running tests. The running velocities corresponding to IAT, IGT, Vmax, Vm3km and CV were 184.8 ± 27.7; 182.8 ± 27.9; 211.1 ± 30; 213.4 ± 32.2 and 199.8 ± 30.4 m.min-1, respectively. Despite the high correlation between the parameters studied, the CV overestimated the IAT and IGT (P 0.05. We concluded that the Vm3km can be used for Vmax estimation and that CV identification on track may be useful for aerobic evaluation as well as for delimiting the high to severe exercise intensity domains. However, the CV does not seem be a good estimation of anaerobic threshold for physically active individuals.

    Full Text Available This study investigates the characteristics of the specific memory factors (processes and content that are associated to the Gsm from the CHC model. Memory tasks with different content, including various aptitude tests and a general intelligence test, were administered to a sample of university students. Two models that relate the general Gsm aptitude, with working memory and memory span, and with verbal-numerical and visual-spatial aptitudes were test- ed. Results indicate good fit indices for both models tested, as well as evidence for a positive regression between Gsm and working memory and between Gsm and visuospatial content. In both models we observed standardized regression of 0.54 and of 0.73 between Gsm and factor g. Implications for the understanding of the relation between memory and intelligence are discussed.

    Twenty six lactic acid bacteria were isolated from sheep's Dhan, a traditional butter made from sheep's milk in Jijel (East of Algeria). These strains belong to three genera: Lactococcus, Leuconostoc and Lactobacillus. The results showed that Lactococcus lactic ssp diacetylactis was the predominant species in this traditional butter. The results of the assessment of the technological aptitude indicate that a major strain has a good acidification aptitude, some of them show good proteolytic activity and only Leuconostoc mesenteroides ssp. dextranicum isolates were able to produce exo polysaccharide.
