    Foreign language aptitude was the subject of much research in the 1950s and has been the subject of intermittent research for the last 30 years. Aptitude is measured by the amount of time it takes an individual to learn. Foreign language aptitude appears to differ from general aptitude or intelligence. One theory states that foreign language…

    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.

    Jackson, Douglas Northrop, III

    2000-09-01

    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

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.

    Directory of Open Access Journals (Sweden)

    2014-02-01

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

    2016-02-01

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

    Full Text Available 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.

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.

  6. Criterios de valoración de la aptitud según profesiones Aptitude assessment criteria depending on the profession

    Directory of Open Access Journals (Sweden)

    M.ª Teresa Magdalena Iglesias

    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.

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 ...

    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.

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

    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 (pmusic test scores (COMB) (p = 0.0056; corrected p = 0.0006). AVPR1A haplotype AVR+RS1 further suggested a positive association with ST (p = 0.0038; corrected p = 0.00184) and COMB (p = 0.0083; corrected p = 0.0040) using haplotype-based association test HBAT. The results suggest that the neurobiology of music perception and production is likely to be related to the pathways affecting intrinsic attachment behavior. PMID:19461995

    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.

    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.

  18. Enhancing the visuo-spatial aptitude of students

    Science.gov (United States)

    Lord, Thomas R.

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

    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.

    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.

    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.

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

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

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

    Science.gov (United States)

    Lawrenz, Frances; Munch, Theodore W.

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

    2011-10-01

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

    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.

    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.

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

    Germann, Paul J.

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

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

    Bender, David S.; Milakofsky, Louis

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

    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.

    Two strains (B7 and Z8) of the Leuconostoc mesenteroides subspecies mesenteroides that were isolated from Algerian camel milk from an initial pool of 13 strains and demonstrated a high ability to inhibit the growth of Listeria spp. were selected and characterised at the phenotypic and genotypic levels. Probiotic profiling and inhibition spectra against food borne pathogens in mixed cultures were also investigated. The bacteriocin produced by L. mesenteroides strain B7 was identified as leucocin B by specific PCR. In vitro studies demonstrated that both Leuconostoc mesenteroides strains exhibited a marked probiotic profile, showing high survival at low pH (2-3 and 4) in the presence of 0.5%, 1%, and 2% of bile salts and at pH 3 in the presence of 3 mg/mL pepsin. Susceptibility testing against antimicrobial agents was also performed for both strains. When tested in a mixed culture with Listeria innocua, Listeria ivanovii, or Staphylococcus aureus, strain B7 reduced the numbers of these species by 1.87, 1.78, and 1.38 log units, respectively. Consequently, these two strains were found to possess good probiotic properties in vitro and a high capacity for Listeria spp. inhibition in mixed cultures. Therefore, these strains have a favourable technological aptitude and a potential application as novel probiotic starters. PMID:24392451

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

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

    Science.gov (United States)

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

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

    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.

    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.

    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'.

    Full Text Available The purpose of this study was to determine the effects of season, locality and the different altitudes at which farms are located, on the physico-chemical composition, morphometric characteristics of fat globules, fatty acid composition and cheese making aptitude of milk of Massese ewe’s raised in 11 flocks from two provinces of north-west Tuscany (Massa Carrara and Lucca. The winter lactation shows higher percentages of casein, lactose and not fat dry matter (P≤0.01; curd firming time (k20 is significantly lower and there is a greater curd firmness (a30 (P≤0.01; while in the summer there is a higher percentage of lipids (P≤0.01. The effect of the season significantly influences (P≤0.01 the size of the fat globules and impacted significantly on the fatty acids composition of the milk. In the hills the milk has a higher percentage of dry matter, protein, casein, fat, phosphorous and not fat dry matter (P≤0.01, whereas it has a lower percentage of lactose and calcium (P≤0.05. The Somatic Cell Count (SCC and the Total Bacterial Count (TBC are statistically greater on the plains (P≤0.01, while milk produced in the hills shows higher quantity of α-linolenic acid and lower saturated fatty acids (P≤0.05. In the two typical rearing areas for Massese ewes we found differences amongst dry matter, fat, phosphorous and SCC, higher (P≤0.01 in the province of Massa Carrara that also had the best rheological parameters, but we found the highest cheese yield (P≤0.05 in the province of Lucca where there are also the greatest weight loss (P≤0.01. The milks produced in the winter season and in hilly areas present the best physico-chemical and nutritional characteristics. However, we found that the technological side should be improved by diversifying cheese-making techniques in relation to the characteristics of milk. In fact, currently these techniques do not fully exploit the potential to transform those milks with the best qualitative

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

    International Nuclear Information System (INIS)

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

  8. 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.

  9. 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.

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).

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

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

    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

    James David

    2010-07-01

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

  5. The use of webcam images to determine tourist-climate aptitude: favourable weather types for sun and beach tourism on the Alicante coast (Spain)

    Ibarra, Emilio Martínez

    2011-05-01

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

    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.

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

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

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

    Full Text Available En la Teoría de la Selección Natural, el concepto de función biológica debe suponerse para definir el concepto de aptitud; y éste debe suponerse para definir el concepto de adaptación y también para explicar el fenómeno que que este último alude. Esos tres conceptos, por otra parte, son especificaciones de tres conceptos de aplicación más universal. El concepto de función biológica es un caso particular del concepto general de función; y el concepto de aptitud especifica el concepto de conveniencia. El concepto de adaptación, mientras tanto, es una especificación del concepto de diseño. La visaulización de esas articulaciones conceptuales permite entender la legitimidad de la naturalización de la teleología operada por el darwinismo.

    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. PMID:22688048

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.

All the considered variability factors showed a highly significant effect (P<0.001 on the lactodynamographic parameters considered. In particular, Massese ewe milk showed the shortest curd speed (k20 and the best coagulum strength (a30 and a45, although clotting time (CT was the highest one. The same trend was registered for skimmed milk and for the most concentrated one (20g. Repeatability values within laboratories were 96% and 97% for CT and k20, lowering for a30 e a45, (respectively 87% and 85%. Much lower coefficients were found for the among laboratories reproducibility, ranging from a maximum of 58% for CT to a minimum of 18% for k20. The wide variability observed indicates that lactodynamographic parameters are comparable only within the same lab.

    The medical certificate of no contraindication to the practice of sport, requires prudence during the exam preceding its writing for medicals and medico-legal reasons. It needs a careful questioning on important points relative to the risk of health problems during a sportive effort, especially to seek for the prodoms which can be found in 7 to 50% of cases. This questioning can sometimes be specific to certain specialities of sport. Actually, even if the concept of mass screening identify for sports people, amateurs or not, is still much debated, we can consider as a reasonable attitude, in consulting with the general medicine, to practice a careful cardiovascular examination and an ECG whose the interpretation, done with the expertise required, could help to detect about 60% of the possible lethal abnormalities to the physical effort. In case of doubt during the exam, the complementary investigations are needed in some cases (echocardiogram, stress testing, myocardial perfusion, electrophysiological endocavitary exploration). After that, the used advices can be given to the sportive candidate to minimize the risks. Despite these precautions, a subit death because of the effort can non totally be avoided. Finally, it must be remembered that the behaviour to have for kid and for elderly person involves certain specificities to know. PMID:24195252

The aim of the study was to identify the personality traits that characterize successful applicants for university studies in the field of software development. Synthetic indicators of quality and performance of their design tasks and exercises were selected as the criteria for candidates’ professional skills. To measure personality traits, the NEO-FFI questionnaire was used, based on the five-factor model by Costa and McCrae. Preliminary results show that expected young designers (N=140 score high on neuroticism and introversion as compared with those designers whose design documentation is of poor quality. They also show a high degree of conscientiousness, which can be seen when their performance of exercises and programming tasks is being evaluated.

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

    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.

    Full Text Available In addition to the engineering knowledge base that has been traditionally taught, today’s undergraduate engineering students need to be given the opportunity to practice a set of skills that will be demanded to them by future employers, namely: creativity, teamwork, problem solving, leadership and the ability to generate innovative ideas. In order to achieve this and educate engineers with both in-depth technical knowledge and professional skills, universities must carry out their own innovating and find suitable approaches that serve their students. This article presents a novel approach that involves university-industry collaboration. It is based on creating a student community for a particular company, allowing students to deal with real industry projects and apply what they are learning in the classroom. A sample project for the German sports brand adidas is presented, along with the project results and evaluation by students and teachers. The university-industry collaborative approach is shown to be beneficial for both students and industry.

    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.

    Velez, G. R.; Sanchez, G. D.

    2003-07-01

    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.

  18. Evaluation of E/EV/SE aptitude to very long duration. Final report of working groups

    International Nuclear Information System (INIS)

    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 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 extensively controlled for previous language experience prior to magnetic resonance imaging (MRI. 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.

    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.

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

    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.

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.

    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.

    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.

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

    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.

    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.

    Full Text Available Setting up a quantitative method for a global evaluation of farmland: application to the Walloon Region (Belgium. To counteract the wasteful use of good quality farmlands by other land uses, we have developed a quantitative method for land evaluation. By splitting up soil map symbols, we have drawn up suitabilility maps for cultivation and for grazing. Farming factors, such as slope, closeness to the farmhouses and size of the farmland blocks, were integrated in the soil suitability map with the help of a geographic information system. The multiplication of the weighted coefficients linked to these factors lead to a global farmland evaluation map. This method has been tested in 10 districts of the Walloon Region. Results seem to be close to farmers practices. The validation problems of this map and the benefits of a factorial and quantitative method are also discussed in this paper.

    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.

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.

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.

    This thesis has as objective the study of the effect of TiO{sub 2} additive on the development of MOX fuel microstructure during sintering in reducing atmosphere. To understand better the mechanisms governing the evolution of microstructure, the behavior of UO{sub 2} in the presence of TiO{sub 2} has been established and the influence of the PuO{sub 2} distribution in the initial state of the material was taken into account. The chapter II is devoted to the bibliographic study of the transport mechanisms responsible of the sintering in the ceramics UO{sub 2} and UO{sub 2}-PuO{sub 2}. The results concerning the influence of TiO{sub 2} upon density, grain size and homogenization are discussed. The following chapter describes the characteristics of initial powder, the procedures and installations of heat treatment, as well as the techniques of characterization used. Then the sintering features of UO{sub 2} alone or in the presence of TiO{sub 2} are presented. It appears that in the last case the surface diffusion becomes sufficient fast so that the distribution of the additive occurs naturally during a slow temperature increase. The fifth chapter treats the effect of UO{sub 2}-PuO{sub 2} preparation upon the initial microstructure of the materials and the role played by the PuO{sub 2} grains in sintering. The potentiality of surface diffusion as a means of PuO{sub 2} spreading in the UO{sub 2} is evaluated and correlated with the reduced capacity of sintering the UO{sub 2} ceramics containing PuO{sub 2}. The last chapter deals with the influence of TiO{sub 2} on the development of microstructure in UO{sub 2}-PuO{sub 2} ceramics. While at temperatures below 1500 deg.C the TiO{sub 2} additive affects the surface diffusion and so the plutonium distribution, at values T{>=} 1600 deg.C the additive gives rise to a dissolution-reprecipitation process taking place in a intergranular liquid phase appeared between UO{sub 2}, PuO{sub 2} and titanium oxide. Thus the objective is the optimizing the temperature conditions, the oxygen potential as sintering gas and the additive concentration in order to obtain a homogeneous (U,Pu)O{sub 2} solid solution independently of the degree of heterogeneity of the initial oxide mixtures 98 refs., 60 figs., 25 tabs.

    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.

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.

    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.
