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

    Science.gov (United States)

    Kreuzpointner, L

    2009-04-01

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

    The aim of this paper - based on the extensive experiences of the authors gained by using one particular work simulator - is to present some promising possibilities of the application of this (and any other similar) work simulator in the field of skill assessment, skill development and vocational aptitude tests of physically disabled persons. During skill assessment and development, as parts of the therapy, the focus is on the disabled functions. During vocational aptitude tests, however, the focus is already on the functions that remained intact and therefore can be the basis of returning to work. Some factual examples are provided to realize the proposed possibilities in practice.

  19. Setting Examinational Subjects and Measuring Vocational Aptitudes in National College Entrance Examination:Breaking the Predicament in the New Wave of Reform%高考科目设置与专业性向测定--破解新一轮高考改革困局

    柳学智

    2015-01-01

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

    Microscopic techniques are an essential part of otolaryngologic practice. These procedures demand advanced psychomotor and visuospatial skills, and trainees possess these abilities to varying degrees. No method currently exists to predict who will possess an aptitude for microscopic surgery. Our goal was to determine whether performance can be predicted by background experiences or skills. Retrospective cohort study. Tertiary academic hospital. Students with no previous surgical experience. Subjects were surveyed on a wide range characteristics thought to affect surgical aptitude, with a primary focus on video gaming and musical training. Subjects performed a microsurgical task using a novel simulator and their performance was assessed by blinded investigators. Forty-six students were assessed. There was no correlation between video gaming and improved microsurgical performance. Rather, video gamers obtained worse scores, although this difference did not reach significance. The majority of students played a musical instrument. Within this group, musicians who began playing at younger ages obtained higher scores, with the highest scores obtained by musicians who began playing before age 6. However, musicians did not obtain higher scores than non-musicians, regardless of their age of initiation. No improvement in microsurgical aptitude was seen in subjects who had a history of video gaming or musical instrument playing.

    2014-12-01

    The decision sciences are increasingly challenged to advance methods for modeling analysts, accounting for both analytic strengths and weaknesses, to improve inferences taken from increasingly large and complex sources of data. We examine whether psychometric measures-personality, cognitive style, motivated cognition-predict analytic performance and whether psychometric measures are competitive with aptitude measures (i.e., SAT scores) as analyst sample selection criteria. A heterogeneous, national sample of 927 participants completed an extensive battery of psychometric measures and aptitude tests and was asked 129 geopolitical forecasting questions over the course of 1 year. Factor analysis reveals four dimensions among psychometric measures; dimensions characterized by differently motivated "top-down" cognitive styles predicted distinctive patterns in aptitude and forecasting behavior. These dimensions were not better predictors of forecasting accuracy than aptitude measures. However, multiple regression and mediation analysis reveals that these dimensions influenced forecasting accuracy primarily through bias in forecasting confidence. We also found that these facets were competitive with aptitude tests as forecast sampling criteria designed to mitigate biases in forecasting confidence while maximizing accuracy. These findings inform the understanding of individual difference dimensions at the intersection of analytic aptitude and demonstrate that they wield predictive power in applied, analytic domains.

    2011-01-01

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

    1992-03-19

    The invention concerns a battery consisting of at least one battery trough, which surrounds individual cells and has a lower inlet opening to connect to a pressurized pipe for a gaseous cooling medium; in its inside it has a lower distribution device for the cooling medium connected to the inlet opening and connected guide ducts taken through the internal space, and at least one upper outlet opening for the cooling medium. To achieve a better cooling system, it is proposed that the battery trough should surround several trough modules, which consist of a module container, whose floor has floor openings flush with the flow ducts between the individual cells and that the distribution device should have vertical separating bars, to the top edge of which the floor of the module container concerned is sealed.

    2001-02-01

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

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

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

  11. Lack of research aptitude in medical education

    Directory of Open Access Journals (Sweden)

    2014-02-01

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

    2007-08-01

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

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

    2016-02-01

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

    Full Text Available Ayurved is an eternal science with sound & absolute principles. Prakruti is an important concept of Ayurveda & plays a very important role in the designing lifestyle of a person for maintenance of health. At the time of union of sperm & ovum, predominance of trigunas, panchamahabhutas & doshas decide the prakruti or constitution of every individual. Once this proportion is set, generally it remains permanent for the lifetime of that individual. Vocational exploration courses offer students the opportunity to research different career possibilities as well as to learn in which vocational areas they have aptitude or talent in. By knowing the prakruti of a particular person, we can get an appropriate idea about his likings or the things he is comfortable with. So, we can guide the person in choosing appropriate profession which will be according to his liking or passion & also he will have the ability to become successful in that particular profession. Through this article, I have made an attempt to evaluate the interrelationship between prakruti & vocational guidance. From this study, I conclude that all the physiological processes are directly controlled by tridosha and thus by the predominant dosha in a particular type of prakriti. Vocational guidance is closely related with prakriti. This conceptual study will be helpful in various vocational guidance centers & also in assigning a particular designation to an employee based on his ability.

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

  10. Evaluation of saddle and driving aptitudes in Monterufoli pony

    2010-01-01

    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.

  16. Space Architecture: The Role, Work and Aptitude

    Science.gov (United States)

    Griffin, Brand

    2014-01-01

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

    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.

    Commercial cinema is both narrative art and a widely-used mass medium that is built upon human stories. Among the contents of these stories there are many vocational aspects. Taking advantage of these circumstances we will proceed to analyze health vocations through eight films. Patch Adams allows us to approach the fulfillment of vocation, which has not been an easy task for women, as we can see in Allá en el setenta y tantos. Vocational fulfillment is at the core of the plot in The Citadel. Something the Lord Made is a good example to illustrate an unfulfilled vocation, in the same way as Awakenings and Arrowsmith represent the fulfillment of an unexpected vocation and a long pursued one. Finally, vocation can demand great sacrifices, which is made crystal clear in Korczak, and when vocation is not strictly followed it might lead to the greatest abominations, which is the case in "The Fugitive. "

    2007-05-01

    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.

    Milovanov, Riia; Tervaniemi, Mari

    2011-01-01

    According to prevailing views, brain organization is modulated by practice, e.g., during musical or linguistic training. Most recent results, using both neuropsychological tests and brain measures, revealed an intriguing connection between musical aptitude and second language linguistic abilities. A significant relationship between higher musical aptitude, better second language pronunciation skills, accurate chord discrimination ability, and more prominent sound-change-evoked brain activation in response to musical stimuli was found. Moreover, regular music practice may also have a modulatory effect on the brain’s linguistic organization and alter hemispheric functioning in those who have regularly practised music for years. These findings, together with their implications, will be introduced and elaborated in our review. PMID:22125541

  5. 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.

    If the components of a battery, including electrodes, separator, electrolyte and the current collectors can be designed as paints and applied sequentially to build a complete battery, on any arbitrary surface, it would have significant impact on the design, implementation and integration of energy storage devices. Here, we establish a paradigm change in battery assembly by fabricating rechargeable Li-ion batteries solely by multi-step spray painting of its components on a variety of materials such as metals, glass, glazed ceramics and flexible polymer substrates. We also demonstrate the possibility of interconnected modular spray painted battery units to be coupled to energy conversion devices such as solar cells, with possibilities of building standalone energy capture-storage hybrid devices in different configurations.

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

    Kontur, F J

    2013-01-01

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

  2. Using dramatic role-play to develop emotional aptitude

    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.

    F. J. Kontur

    2015-02-01

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

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

    Directory of Open Access Journals (Sweden)

    Abbas Zare-ee

    2014-10-01

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

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

    Artistic creativity forms the basis of music culture and music industry. Composing, improvising and arranging music are complex creative functions of the human brain, which biological value remains unknown. We hypothesized that practicing music is social communication that needs musical aptitude and even creativity in music. In order to understand the neurobiological basis of music in human evolution and communication we analyzed polymorphisms of the arginine vasopressin receptor 1A (AVPR1A), serotonin transporter (SLC6A4), catecol-O-methyltranferase (COMT), dopamin receptor D2 (DRD2) and tyrosine hydroxylase 1 (TPH1), genes associated with social bonding and cognitive functions in 19 Finnish families (n = 343 members) with professional musicians and/or active amateurs. All family members were tested for musical aptitude using the auditory structuring ability test (Karma Music test; KMT) and Carl Seashores tests for pitch (SP) and for time (ST). Data on creativity in music (composing, improvising and/or arranging music) was surveyed using a web-based questionnaire. Here we show for the first time that creative functions in music have a strong genetic component (h(2) = .84; composing h(2) = .40; arranging h(2) = .46; improvising h(2) = .62) in Finnish multigenerational families. We also show that high music test scores are significantly associated with creative functions in music (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.

    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.

    Hu, Xiaochen; Ackermann, Hermann; Martin, Jason A; Erb, Michael; Winkler, Susanne; Reiterer, Susanne M

    2013-12-01

    Individual differences in second language (L2) aptitude have been assumed to depend upon a variety of cognitive and personality factors. Especially, the cognitive factor phonological working memory has been conceptualised as language learning device. However, strong associations between phonological working memory and L2 aptitude have been previously found in early-stage learners only, not in advanced learners. The current study aimed at investigating the behavioural and neurobiological predictors of advanced L2 learning. Our behavioural results showed that phonetic coding ability and empathy, but not phonological working memory, predict L2 pronunciation aptitude in advanced learners. Second, functional neuroimaging revealed this behavioural trait to be correlated with hemodynamic responses of the cerebral network of speech motor control and auditory-perceptual areas. We suggest that the acquisition of L2 pronunciation aptitude is a dynamic process, requiring a variety of neural resources at different processing stages over time. Copyright © 2012 Elsevier Inc.

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

    Job environments have been fundamentally changed by globalization and modern technological innovation. Qualitative workload is expected to increase more than quantitative workload through this rapid technological innovation. Especially, in developed countries, qualitative workload is expected to become a primary job-related stress factor in the near future. Therefore, it is essential to clarify the characteristics of qualitative workload and to determine how to cope with it effectively. Since job stress level and ego aptitude are correlated and qualitative overload increases stress, we examined qualitative overload and ego aptitude among male Japanese cutting-edge science researchers. The Brief Job Stress Questionnaire and the Tokyo University Ego-gram New Version II were distributed to all workers at two Japanese academic institutions. Qualitative overload and adult ego aptitude, representing rationalism, were higher in male researchers than in the Japanese male general sample. In addition, adapted child aptitude, representing obedience, was lower in male researchers. Lack of supervisor support was positively associated with qualitative overload, and nurturing parent ego aptitude was negatively associated with it. Male researchers had higher levels of qualitative overload. Increasing supervisor support is essential in decreasing this qualitative overload. Furthermore, enhancement of nurturing parent ego aptitude (i.e., careful consideration for others) is also important for qualitative overload management.

    The energy density in conventional capacitors is limited by sparking. We present nano-capacitor arrays, where - like in laser diodes and quantum wells [1] - quantization prevents dielectric breakthrough. We show that the energy density and the power/weight ratio are very high, possibly larger than in hydrogen [2]. Digital batteries are a potential clean energy source for cars, laptops, and mobile devices. The technology is related to flash drives. However, because of the high energy density, safety is a concern. Digital batteries can be easily and safely charged and discharged. In the discharged state they pose no danger. Even if a charged digital battery were to explode, it would produce no radioactive waste, no long-term radiation, and probably could be designed to produce no noxious chemicals. We discuss methodologies to prevent shorts and other measures to make digital batteries safe. [1] H. Higuraskh, A. Toriumi, F. Yamaguchi, K. Kawamura, A. Hubler, Correlation Tunnel Device, U. S.

    2010-07-12

    The very high theoretical capacity of lithium (3829 mAh/g) provided a compelling rationale from the 1970's onward for development of rechargeable batteries employing the elemental metal as an anode. The realization that some transition metal compounds undergo reductive lithium intercalation reactions reversibly allowed use of these materials as cathodes in these devices, most notably, TiS{sub 2}. Another intercalation compound, LiCoO{sub 2}, was described shortly thereafter but, because it was produced in the discharged state, was not considered to be of interest by battery companies at the time. Due to difficulties with the rechargeability of lithium and related safety concerns, however, alternative anodes were sought. The graphite intercalation compound (GIC) LiC{sub 6} was considered an attractive candidate but the high reactivity with commonly used electrolytic solutions containing organic solvents was recognized as a significant impediment to its use. The development of electrolytes that allowed the formation of a solid electrolyte interface (SEI) on surfaces of the carbon particles was a breakthrough that enabled commercialization of Li-ion batteries. In 1990, Sony announced the first commercial batteries based on a dual Li ion intercalation system. These devices are assembled in the discharged state, so that it is convenient to employ a prelithiated cathode such as LiCoO{sub 2} with the commonly used graphite anode. After charging, the batteries are ready to power devices. The practical realization of high energy density Li-ion batteries revolutionized the portable electronics industry, as evidenced by the widespread market penetration of mobile phones, laptop computers, digital music players, and other lightweight devices since the early 1990s. In 2009, worldwide sales of Li-ion batteries for these applications alone were US$ 7 billion.

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 (p<.0001. We discovered an overall haplotype association with AVPR1A gene (markers RS1 and RS3 and KMT (p = 0.0008; corrected p = 0.00002, SP (p = 0.0261; corrected p = 0.0072 and combined music 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

    Two categories of battery chargers exist: external ones and internal ones. In the first category two types are developing today: direct contact chargers for fast and normal charging, and contact-less chargers. The second category is mainly devoted to vehicle applications (automobiles, trains etc..) and must fulfill strict technical-economical criteria (cost, weight, size, vibrations and shocks resistance, service life, power etc..). This article presents todays advance in chargers technology: 1 - general principles (different battery types, charging profiles, multiple chargers); 2 - chargers for low-cost applications (direct chargers, constant voltage chargers, voltage regulated chargers, integrated chargers, applications); 3 - advanced sinusoidal absorption chargers (general scheme, safety constraints, energy conversion structures ('buck', 'boost', 'cuck', 'flyback' switching power supplies), regulation control); 4 - concrete cases: single output and multi-output chargers.

    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.

    2010-01-01

    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.

    Methods of using specific operational charge and discharge parameters to extend the life of alkaline batteries are disclosed. The methods can be used with any commercial primary or secondary alkaline battery, as well as with newer alkaline battery designs, including batteries with flowing electrolyte. The methods include cycling batteries within a narrow operating voltage window, with minimum and maximum cut-off voltages that are set based on battery characteristics and environmental conditions. The narrow voltage window decreases available capacity but allows the batteries to be cycled for hundreds or thousands of times.

  10. he (UnAttractiveness of Vocational and Technical Education: Theoretical Background

    Directory of Open Access Journals (Sweden)

    Miha Lovšin

    2014-03-01

    Full Text Available This paper considers the problem of the lack of attractiveness of vocational and technical education via a review of legislation on counselling practices, implementing documents, and the social factors by means of which the education system can influence the individual’s decision. It is apparent that legislation regulating the organisation and content of career counselling services in educational sector is inadequate. The organisation of career counselling at the level of implementation is also inadequate. Counsellors advise individuals on the basis of their academic results and the results of aptitude tests. Counselling practices deriving from theories that place career planning and management skills in the foreground are more rarely represented. Theories that treat career decisions as a social process show that at the level of the student population the choice of the type of school is a rational decision based primarily on the economic position and level of education to which a specific educational pathway is generally supposed to lead. The lower attractiveness of vocational and technical education coincides with the fact that representatives of lower social classes have a weaker economic position and more frequently have vocational and technical education qualifications than representatives of higher social classes. Nevertheless, the trend of high unemployment among young people with academic qualifications, which opposite of the traditional situation, indicates that it will be necessary to include career planning and management skills in the educational contents of institutionalised and formal education as a whole.

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

    Directory of Open Access Journals (Sweden)

    Sebastian Halder

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

    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.

    2015-02-01

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

    Energy Technology Data Exchange (ETDEWEB)

    Thompson, M. E.

    1985-09-03

    A battery energizer for button batteries, such as zinc-silver oxide or zinc-mercuric oxide batteries, that are normally considered unchargeable, provides for energizing of the batteries in a safe and simple manner. A solar cell having a maximum current output (e.g., 20 milliamps) is operatively connected to terminals for releasably receiving a button battery. A light emitting diode, or like indicator, provides an indication of when the battery is fully energized, and additionally assists in preventing overenergization of the battery. The solar cell, terminals, LED, and the like can be mounted on a nonconductive material mounting plate which is mounted by a suction cup and hook to a window, adjacent a light bulb, or the like. A battery charger for conventional dry cell rechargeable batteries (such as nickel-cadmium batteries) utilizes the solar cells, and LED, and a zener diode connected in parallel with terminals. An adaptor may be provided with the terminal for adapting them for use with any conventional size dry cell battery, and a simple dummy battery may be utilized so that less than the full complement of batteries may be charged utilizing the charger.

    Science.gov (United States)

    Gobelet, C; Luthi, F; Al-Khodairy, A T; Chamberlain, M A

    2007-09-15

    Vocational rehabilitation is by definition a multidisciplinary intervention in a process linked to the facilitation of return to work or to the prevention of loss of the work. Clinical staff in contact with a person who has lost his job (general practitioner, specialized physician) must promote vocational rehabilitation. Medical rehabilitation for those with disabilities, whether new or old, has to be followed without delay by vocational rehabilitation. It is even better if these two intertwined processes are overlapping. They involve many professionals including physiotherapists, occupational therapists, psychologists, vocational trainers, job counsellors, teachers, case-managers, job placement agencies. Vocational rehabilitation has a financial cost, borne by many state organizations (security, social system, social affairs) as well as by employers and private insurances, which are in case of accident, concerned by this process. However, the evidence suggests that this is recouped 2- to 10-fold as suggested by the British Society of Rehabilitation Medicine.

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

    Lauer, Jillian E; Lourenco, Stella F

    2016-10-01

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

    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 20,532) 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.

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.

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

    Electric vehicles that can't reach trolley wires need batteries. In the early 1900's electric cars disappeared when owners found that replacing the car's worn-out lead-acid battery costs more than a new gasoline-powered car. Most of today's electric cars are still propelled by lead-acid batteries. General Motors in their prototype Impact, for example, used starting-lighting-ignition batteries, which deliver lots of power for demonstrations, but have a life of less than 100 deep discharges. Now promising alternative technology has challenged the world-wide lead miners, refiners, and battery makers into forming a consortium that sponsors research into making better lead-acid batteries. Horizon's new bipolar battery delivered 50 watt-hours per kg (Wh/kg), compared with 20 for ordinary transport-vehicle batteries. The alternatives are delivering from 80 Wh/kg (nickel-metal hydride) up to 200 Wh/kg (zinc-bromine). A Fiat Panda traveled 260 km on a single charge of its zinc-bromine battery. A German 3.5-ton postal truck traveled 300 km with a single charge in its 650-kg (146 Wh/kg) zinc-air battery. Its top speed was 110 km per hour.

    2012-02-08

    Water desalination is an important approach to provide fresh water around the world, although its high energy consumption, and thus high cost, call for new, efficient technology. Here, we demonstrate the novel concept of a "desalination battery", which operates by performing cycles in reverse on our previously reported mixing entropy battery. Rather than generating electricity from salinity differences, as in mixing entropy batteries, desalination batteries use an electrical energy input to extract sodium and chloride ions from seawater and to generate fresh water. The desalination battery is comprised by a Na(2-x)Mn(5)O(10) nanorod positive electrode and Ag/AgCl negative electrode. Here, we demonstrate an energy consumption of 0.29 Wh l(-1) for the removal of 25% salt using this novel desalination battery, which is promising when compared to reverse osmosis (~ 0.2 Wh l(-1)), the most efficient technique presently available.

    Potassium may exhibit advantages over lithium or sodium as a charge carrier in rechargeable batteries. Analogues of Prussian blue can provide millions of cyclic voltammetric cycles in aqueous electrolyte. Potassium intercalation chemistry has recently been demonstrated compatible with both graphite and nongraphitic carbons. In addition to potassium-ion batteries, potassium-O2 (or -air) and potassium-sulfur batteries are emerging. Additionally, aqueous potassium-ion batteries also exhibit high reversibility and long cycling life. Because of potentially low cost, availability of basic materials, and intriguing electrochemical behaviors, this new class of secondary batteries is attracting much attention. This mini-review summarizes the current status, opportunities, and future challenges of potassium secondary batteries.

    Serious questions have arisen about the environmental damage caused by cadmium from rechargeable nickel cadmium batteries in municipal solid waste. Sweden, Belgium, several American states and Canadian provinces either have enacted, or are contemplating legislation to address disposal of cadmium-containing batteries. In a preemptive strike, industry is now developing its own recycling initiatives through the Rechargeable Battery Recycling Corporation (RBRC), established in the USA in 1996, and launched in Ontario in September 1997. The primary role of RBRC in Canada is to collect licensee funds from participating battery manufacturers and administer Ni-Cd battery recycling programs. RBRC is also tasked to establish consensus within provincial and federal regulatory bodies with regard to the issue of Ni-Cd battery waste management. Mounting concerns are expressed about conflicting statistics as to the volume of batteries collected for recycling, and more particularly, about the method of recycling that RBRC may be contemplating. The fear is that in the absence of a profitable incentive to battery distributors, or a profitable product that might result from the recycled material, combined with the pressure of the high cost of recycling Ni-Cd batteries, many of the recovered batteries could end up in landfills sites for hazardous wastes. This is especially likely since Ni-Cd batteries are not banned from landfill sites in Ontario. It is the view of this author that while RBRC`s `charge up to recycle` program makes all the right noises, it lacks a meaningful approach to actually increase diversion, measure results, or to prevent Ni-Cd rechargeable batteries from entering the solid waste stream.

    1997-03-01

    Battery packs for portable equipment must sometimes accommodate conflicting requirements to meet application needs. An electronically configurable battery pack was developed to support two highly different operating modes, one requiring very low power consumption at a low voltage and the other requiring high power consumption at a higher voltage. The configurable battery pack optimizes the lifetime and performance of the system by making the best use of all available energy thus enabling the system to meet its goals of operation, volume, and lifetime. This paper describes the cell chemistry chosen, the battery pack electronics, and tradeoffs made during the evolution of its design.

    If we consider the Statistics there is drastic increase in dependence of batteries from year to year, due to necessity of power storage equipment at homes, power generating off grid and on grid Wind, PV systems, etc.. Where wind power is leading in renewable sector, there is a need to look at its development. Considering the scenario in India, most of the wind resource areas are far away from grid and the remaining areas which are near to grid are of low wind currents which is of no use connecting these equipment directly to grid. So, there is a need for a power storage utility to be integrated, such as the BNB (Ballistic Negatron Battery). In this situation a country like India need a battery which should be reliable, cheap and which can be industrialized. So this paper presents the concept of working, design, operation, adaptability of a Ballistic Negatron Battery. Unlike present batteries with low energy density, huge size, more weight, more charging time and low resistant to wear level, this Ballistic Negatron Battery comes with, 1) High energy storage capability (many multiples more than the present most advanced battery). 2) Very compact in size. 3) Almost negligible in weight compared to present batteries. 4) Charges with in very less time. 5) Never exhibits a wear level greater than zero. Seems like inconceivable but adoptable with simple physics. This paper will explains in detail the principle, model, design, construction and practical considerations considered in making this battery. (Author)

    The operating temperature is critical in achieving the right balance between performance, cost, and life for both Li-ion batteries and ultracapacitors. The chemistries of advanced energy-storage devices - such as lithium-based batteries - are very sensitive to operating temperature. High temperatures degrade batteries faster while low temperatures decrease their power and capacity, affecting vehicle range, performance, and cost. Understanding heat generation in battery systems - from the individual cells within a module, to the inter-connects between the cells, and across the entire battery system - is imperative for designing effective thermal-management systems and battery packs. At NREL, we have developed unique capabilities to measure the thermal properties of cells and evaluate thermal performance of battery packs (air or liquid cooled). We also use our electro-thermal finite element models to analyze the thermal performance of battery systems in order to aid battery developers with improved thermal designs. NREL's tools are used to meet the weight, life, cost, and volume goals set by the U.S. Department of Energy for electric drive vehicles.

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

    A battery warming device has been designed which uses waste heat from an operating internal combustion engine to warm a battery. A portion of the waste heat is stored in the sensible and latent heat of a phase change type material for use in maintaining the battery temperature after the engine is shut off. The basic design of the device consists of a Phase Change Material (PCM) reservoir and a simple heat exchanger connected to the engineer's cooling system. Two types of units were built, tested and field trialed. A strap-on type which was strapped to the side of an automotive battery and was intended for the automotive after-market and a tray type on which a battery or batteries sat. This unit was intended for the heavy duty truck market. It was determined that both types of units increased the average cranking power of the batteries they were applied to. Although there were several design problems with the units such as the need for an automatic thermostatically controlled bypass valve, the overall feeling is that there is a market opportunity for both the strap-on and tray type battery warming units.

    2011-10-17

    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. 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. 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. These data indicate common brain mechanisms underlying reading and music abilities that relate to how the nervous system responds to regularities in auditory input.

    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.

  5. Strategies for Translating Vocative Texts

    2014-12-01

    Full Text Available The paper deals with the linguistic and cultural elements of vocative texts and the techniques used in translating them by giving some examples of texts that are typically vocative (i.e. advertisements and instructions for use. Semantic and communicative strategies are popular in translation studies and each of them has its own advantages and disadvantages in translating vocative texts. The advantage of semantic translation is that it takes more account of the aesthetic value of the SL text, while communicative translation attempts to render the exact contextual meaning of the original text in such a way that both content and language are readily acceptable and comprehensible to the readership. Focus is laid on the strategies used in translating vocative texts, strategies that highlight and introduce a cultural context to the target audience, in order to achieve their overall purpose, that is to sell or persuade the reader to behave in a certain way. Thus, in order to do that, a number of advertisements from the field of cosmetics industry and electronic gadgets were selected for analysis. The aim is to gather insights into vocative text translation and to create new perspectives on this field of research, now considered a process of innovation and diversion, especially in areas as important as economy and marketing.

  6. Battery Pack Thermal Design

    Pesaran, Ahmad

    2016-06-14

    This presentation describes the thermal design of battery packs at the National Renewable Energy Laboratory. A battery thermal management system essential for xEVs for both normal operation during daily driving (achieving life and performance) and off-normal operation during abuse conditions (achieving safety). The battery thermal management system needs to be optimized with the right tools for the lowest cost. Experimental tools such as NREL's isothermal battery calorimeter, thermal imaging, and heat transfer setups are needed. Thermal models and computer-aided engineering tools are useful for robust designs. During abuse conditions, designs should prevent cell-to-cell propagation in a module/pack (i.e., keep the fire small and manageable). NREL's battery ISC device can be used for evaluating the robustness of a module/pack to cell-to-cell propagation.

  7. Electrolytes for advanced batteries

    1999-09-01

    The choices of the components of the electrolyte phase for advanced batteries (lithium and lithium ion batteries) are very sensitive to the electrodes which are used. There are also a number of other requirements for the electrolyte phase, which depend on the cell design and the materials chosen for the battery. The difficulty of choice is compounded when the cell is a rechargeable one. This paper looks at each of these requirements and the degree to which they are met for lithium and lithium ion batteries. The discussion is broken into sections on anode or negative electrode stability requirements, cathode or positive electrode stability requirements, conductivity needs, viscosity and wetting requirements. The effects of these properties and interactions on the performance of batteries are also discussed. (orig.)

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

    This study evaluated virtual reality (VR) simulation for endovascular training of medical students to determine whether innate perceptual, visuospatial, and psychomotor aptitude (VSA) can predict initial and plateau phase of technical endovascular skills acquisition. Twenty medical students received didactic and endovascular training on a commercially available VR simulator. Each student treated a series of 10 identical noncomplex renal artery stenoses endovascularly. The simulator recorded performance data instantly and objectively. An experienced interventionalist rated the performance at the initial and final sessions using generic (out of 40) and procedure-specific (out of 30) rating scales. VSA were tested with fine motor dexterity (FMD, Perdue Pegboard), psychomotor ability (minimally invasive virtual reality surgical trainer [MIST-VR]), image recall (Rey-Osterrieth), and organizational aptitude (map-planning). VSA performance scores were correlated with the assessment parameters of endovascular skills at commencement and completion of training. Medical students exhibited statistically significant learning curves from the initial to the plateau performance for contrast usage (medians, 28 vs 17 mL, P generic and procedure-specific rating scales improved significantly (10 vs 25, P generic skills at the end of training (r(s) = .587, P = .006). Simulator-based training in endovascular skills improved performance in medical students. There were significant correlations between initial endovascular skill and fine motor dexterity as well as with image recall at end of the training period. In addition to current recruitment strategies, VSA may be a useful tool for predictive validity studies.

    2013-01-01

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

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

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

  1. Overcoming the Range Limitation of Medium-Duty Battery Electric Vehicles through the use of Hydrogen Fuel-Cells

    Energy Technology Data Exchange (ETDEWEB)

    2013-10-01

    Battery electric vehicles possess great potential for decreasing lifecycle costs in medium-duty applications, a market segment currently dominated by internal combustion technology. Characterized by frequent repetition of similar routes and daily return to a central depot, medium-duty vocations are well positioned to leverage the low operating costs of battery electric vehicles. Unfortunately, the range limitation of commercially available battery electric vehicles acts as a barrier to widespread adoption. This paper describes the National Renewable Energy Laboratory's collaboration with the U.S. Department of Energy and industry partners to analyze the use of small hydrogen fuel-cell stacks to extend the range of battery electric vehicles as a means of improving utility, and presumably, increasing market adoption. This analysis employs real-world vocational data and near-term economic assumptions to (1) identify optimal component configurations for minimizing lifecycle costs, (2) benchmark economic performance relative to both battery electric and conventional powertrains, and (3) understand how the optimal design and its competitiveness change with respect to duty cycle and economic climate. It is found that small fuel-cell power units provide extended range at significantly lower capital and lifecycle costs than additional battery capacity alone. And while fuel-cell range-extended vehicles are not deemed economically competitive with conventional vehicles given present-day economic conditions, this paper identifies potential future scenarios where cost equivalency is achieved.

    Diffuse reflectance IR spectroscopy (DRIFTS) was used to investigate the effect of accelerated aging on LiSi based anodes in simulated MC3816 batteries. DRIFTS spectra showed that the oxygen, carbonate, hydroxide and sulfur content of the anodes changes with aging times and temperatures, but not in a monotonic fashion that could be correlated to phase evolution. Bands associated with sulfur species were only observed in anodes taken from batteries aged in wet environments, providing further evidence for a reaction pathway facilitated by H2S transport from the cathode, through the separator, to the anode. Loss of battery capacity with accelerated aging in wet environments was correlated to loss of FeS2 in the catholyte pellets, suggesting that the major contribution to battery performance degradation results from loss of active cathode material.

    Battery energy storage systems, comprising lead-acid batteries, power conversion systems, and control systems, are used by three main groups: power generating utilities, power distributing utilities, and major power consumers (such as electric furnace foundries). The principal advantages of battery energy storage systems to generating utilities include load leveling, frequency control, spinning reserve, modular construction, convenient siting, no emissions, and investment deferral for new generation and transmission equipment. Power distributing utilities and major power consumers can avoid costly demand changes by discharging their batteries at peak periods and then recharging with lower cost off-peak power (say, at night). Battery energy storage systems are most cost effective when designed for discharge periods of less than 5 h; other systems (for example, pumped water storage) are better suited for longer discharges. It is estimated that by the year 2000 there will be a potential need for 4000 MW of battery energy storage. New construction of five plants totaling 100 MW is presently scheduled for completion by the Puerto Rico Electric Power Authority between 1992 and 1995.

  2. Lithium use in batteries

    Science.gov (United States)

    Goonan, Thomas G.

    2012-01-01

    Lithium has a number of uses but one of the most valuable is as a component of high energy-density rechargeable lithium-ion batteries. Because of concerns over carbon dioxide footprint and increasing hydrocarbon fuel cost (reduced supply), lithium may become even more important in large batteries for powering all-electric and hybrid vehicles. It would take 1.4 to 3.0 kilograms of lithium equivalent (7.5 to 16.0 kilograms of lithium carbonate) to support a 40-mile trip in an electric vehicle before requiring recharge. This could create a large demand for lithium. Estimates of future lithium demand vary, based on numerous variables. Some of those variables include the potential for recycling, widespread public acceptance of electric vehicles, or the possibility of incentives for converting to lithium-ion-powered engines. Increased electric usage could cause electricity prices to increase. Because of reduced demand, hydrocarbon fuel prices would likely decrease, making hydrocarbon fuel more desirable. In 2009, 13 percent of worldwide lithium reserves, expressed in terms of contained lithium, were reported to be within hard rock mineral deposits, and 87 percent, within brine deposits. Most of the lithium recovered from brine came from Chile, with smaller amounts from China, Argentina, and the United States. Chile also has lithium mineral reserves, as does Australia. Another source of lithium is from recycled batteries. When lithium-ion batteries begin to power vehicles, it is expected that battery recycling rates will increase because vehicle battery recycling systems can be used to produce new lithium-ion batteries.

    2012-01-01

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

    Full Text Available Rapid changes are taking place in industry, the labor market, work to work organization. The changes of taking places in industry have an important implication for Vocational Education and Training (VET. These widespread changes have significant implications for the learning requirement of workers and for the pedagogical methods to facilitate that learning. This paper focuses in the learning of instructor, learners in the perspective of their readiness with teaching and learning challenge in VET. Some theoretical consideration in behavioral and cognitive psychology will be discussed derived from the concept of learning content vocational institutions; pedagogical strategies such as demonstration, practice and feedback implemented by the instructors for learning occur. The learners’ preferences based on their characteristics to cater their ability to learn in VET. Learners’ learning styles were investigated to identify their preferences in learning and match with the curriculum and practices in teaching VET. The shift in pedagogical orientation will focus in potential of individual, engage learners in development of their own vocational knowledge and skills. VET instructors and trainers must be able to recognize and adapt their teaching and learning practice in order to response to these needs.

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

    Directory of Open Access Journals (Sweden)

    Jeremy C Borniger

    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.

    Full Text Available Introducción: la OMS y la Unicef recomiendan lactancia materna exclusiva durante los primeros 6 meses de vida, y complementada, al menos, hasta los 2 años; sin embargo, los resultados no son los esperados. Objetivo: evaluar la relación entre la planificación del embarazo, la lactancia en hijos anteriores, la aptitud referida para lactar y los conocimientos sobre lactancia materna de las gestantes en su tercer trimestre, de los Policlínicos "Luis Augusto Turcios Lima" y "Mártires del 9 de Abril", del municipio San José de las Lajas. Métodos: se realizó un estudio analítico y transversal, entre marzo de 2010 y marzo de 2011. De 192 gestantes en su tercer trimestre, y que cumplieron los criterios de inclusión, se estudiaron: hijos previos y si recibieron lactancia materna, planificación, deseos del embarazo, aptitudes referidas, así como conocimientos sobre la lactancia. Se aplicaron 22 preguntas y se estableció un sistema de puntaje. Resultados: algo más de la mitad de las madres se consideraron aptas para la lactancia, y asumieron que poseían los conocimientos necesarios para lograrlo, pero menos de la quinta parte mostró poseerlos. Las gestantes que obtuvieron valores superiores en el cuestionario fueron: las que tenían un hijo previo, las que ya habían ofrecido lactancia materna exclusiva de 4 a 6 meses, y las que deseaban y habían planificado su embarazo. Conclusiones: aunque la mayoría de las gestantes consideraron que estaban aptas para la lactancia materna, no demostraron tener los conocimientos necesarios para asumirla exitosamente.

  16. Used batteries - REMINDER

    CERN Document Server

    2006-01-01

    With colder weather drawing in, it is quite likely that older car batteries will fail. On this subject, the Safety Commission wishes to remind everyone that CERN is not responsible for the disposal of used batteries from private vehicles. So please refrain from abandoning them on pavements or around or inside buildings. Used batteries can be disposed of safely, free-of-charge and without any damage to the environment at waste disposal sites (déchetteries) close to CERN in both France (Ain and Haute-Savoie) and in the Canton of Geneva in Switzerland (Cheneviers). Since the average car battery lasts a number of years, this only represents a small effort on your part over the whole lifetime of your vehicle. Most people don't need reminding that car batteries contain concentrated sulphuric acid, which can cause severe burns. Despite this, we frequently find them casually dumped in scrap metal bins! For more information, please contact R. Magnier/SC-GS 160879 We all have a responsibility for safety and th...

  18. Reforming Vocational Education and Training

    DEFF Research Database (Denmark)

    Friche, Nanna; Kondrup, Sissel

    The systems of vocational education and training are facing a number of challenges in many European countries. The share of young people who are neither employed, nor in education or training (NEET) is still higher for graduates from upper secondary VET than from upper secondary general programmes....... Students who enter vocational programmes are less likely to graduate than those who are enrolled in general programmes. Moreover, they are nearly five times less likely to enrol in further education than graduates from general secondary schools with similar proficiency in literacy (OECD 2015). These trends...... means that the challenges are twofold. First, the VET systems are required to offer double qualifications, which give access not only to skilled employment, but also to higher education (Deissinger et.al 2013). Secondly, the VET systems are met by diverse demands to be social inclusive and exclusive...

    A miniaturized microfluidic battery is proposed, which is the first membraneless redox battery demonstrated to date. This unique concept capitalizes on dual-pass flow-through porous electrodes combined with stratified, co-laminar flow to generate electrical power on-chip. The fluidic design is symmetric to allow for both charging and discharging operations in forward, reverse, and recirculation modes. The proof-of-concept device fabricated using low-cost materials integrated in a microfluidic chip is shown to produce competitive power levels when operated on a vanadium redox electrolyte. A complete charge/discharge cycle is performed to demonstrate its operation as a rechargeable battery, which is an important step towards providing sustainable power to lab-on-a-chip and microelectronic applications.

    A technique is proposed for buffer storage batteries of the NKG type with voltage-adding storage batteries. These batteries (B) guarantee comparatively narrow range of change in the voltage for load with discharge of the storage batteries of the main B to the assigned minimum voltage. The purpose of the calculation is to determine the number of voltage-adding B and the number of storage batteries in each of them. The initial data for calculation are minimum and maximum values of voltage for load and storage batteries of the main B. Expressions have been obtained for determining the depth of the discharge and the final expression for determining the depth of the discharge and the final discharge voltage of the storage batteries of each voltage-adding B. The necessary formulas are presented and the order for making the calculation is given.

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

    Note from the TIS Division: Although it is not an obligation for CERN to collect, store and dispose of used batteries from private vehicles, they are often found abandoned on the site and even in the scrap metal bins. As well as being very dangerous (they contain sulphuric acid which is highly corrosive), this practise costs CERN a non-negligible amount of money to dispose of them safely. The disposal of used batteries in the host state could not be simpler, there are 'déchetteries' in neighbouring France at Saint-Genis, Gaillard and Annemasse as well as in other communes. In Geneva Canton the centre de traitement des déchets spéciaux, at Cheneviers on the river Rhône a few kilometers from CERN, will dispose of your batterie free of charge. So we ask you to use a little common sense and to help protect the environnement from the lead and acid in these batteries and even more important, to avoid the possibility of a colleague being seriously injured.

    1992-01-01

    An apparatus [10] is disclosed for a lightweight bipolar battery of the end-plate cell stack design. Current flow through a bipolar cell stack [12] is collected by a pair of copper end-plates [16a,16b] and transferred edgewise out of the battery by a pair of lightweight, low resistance copper terminals [28a,28b]. The copper terminals parallel the surface of a corresponding copper end-plate [16a,16b] to maximize battery throughput. The bipolar cell stack [12], copper end-plates [16a,16b] and copper terminals [28a,28b] are rigidly sandwiched between a pair of nonconductive rigid end-plates [20] having a lightweight fiber honeycomb core which eliminates distortion of individual plates within the bipolar cell stack due to internal pressures. Insulating foam [30] is injected into the fiber honeycomb core to reduce heat transfer into and out of the bipolar cell stack and to maintain uniform cell performance. A sealed battery enclosure [ 22] exposes a pair of terminal ends [26a,26b] for connection with an external circuit.

  18. Modular Battery Charge Controller

    Button, Robert; Gonzalez, Marcelo

    2009-01-01

    A new approach to masterless, distributed, digital-charge control for batteries requiring charge control has been developed and implemented. This approach is required in battery chemistries that need cell-level charge control for safety and is characterized by the use of one controller per cell, resulting in redundant sensors for critical components, such as voltage, temperature, and current. The charge controllers in a given battery interact in a masterless fashion for the purpose of cell balancing, charge control, and state-of-charge estimation. This makes the battery system invariably fault-tolerant. The solution to the single-fault failure, due to the use of a single charge controller (CC), was solved by implementing one CC per cell and linking them via an isolated communication bus [e.g., controller area network (CAN)] in a masterless fashion so that the failure of one or more CCs will not impact the remaining functional CCs. Each micro-controller-based CC digitizes the cell voltage (V(sub cell)), two cell temperatures, and the voltage across the switch (V); the latter variable is used in conjunction with V(sub cell) to estimate the bypass current for a given bypass resistor. Furthermore, CC1 digitizes the battery current (I1) and battery voltage (V(sub batt) and CC5 digitizes a second battery current (I2). As a result, redundant readings are taken for temperature, battery current, and battery voltage through the summation of the individual cell voltages given that each CC knows the voltage of the other cells. For the purpose of cell balancing, each CC periodically and independently transmits its cell voltage and stores the received cell voltage of the other cells in an array. The position in the array depends on the identifier (ID) of the transmitting CC. After eight cell voltage receptions, the array is checked to see if one or more cells did not transmit. If one or more transmissions are missing, the missing cell(s) is (are) eliminated from cell

    In recent years, our country has announced a series of policies and measures and invested a large amount of funds to encourage and support the development of vocational education, so vocational education has been given special attention. The continuous expansion of university enrollment has resulted in the continuous decrease of higher vocational students, and their lev-els of knowledge and ability are uneven. To improve the teaching quality and teaching management of higher vocational account-ing, it is imperative to reform the traditional teaching model which possesses the same schedule and depth, so hierarchical teaching which teaches students in accordance with their aptitude emerges as required. Based on the origin and connotation of hierarchical teaching, this paper explored its necessity in accounting teaching as well as the measures of hierarchical education.%近些年来,国家出台了一系列的政策与措施,投入了大量的资金鼓励和支持职业教育的发展,职业教育因此备受瞩目。而高校的不断扩招,导致高职生源数量不断减少,且知识、能力水平参差不齐。要提高高职会计专业的教学质量和教学管理水平,对传统的、进度和深度都相同的教学模式进行改革势在必行,因材施教式的分层教学模式便应运而生。文章基于分层教学的起源与内涵,对高职会计专业分层教学的必要性和分层教育的措施进行了探究。

    LiFeBATT has concentrated its recent testing and evaluation on the safety of its batteries. There appears to be a good margin of safety with respect to overheating of the cells and the cases being utilized for the batteries are specifically designed to dissipate any heat built up during charging. This aspect of LiFeBATT’s products will be even more fully investigated, and assuming ongoing positive results, it will become a major component of marketing efforts for the batteries. LiFeBATT has continued to receive prismatic 20 Amp hour cells from Taiwan. Further testing continues to indicate significant advantages over the previously available 15 Ah cells. Battery packs are being assembled with battery management systems in the Danville facility. Comprehensive tests are underway at Sandia National Laboratory to provide further documentation of the advantages of these 20 Ah cells. The company is pursuing its work with Hybrid Vehicles of Danville to critically evaluate the 20 Ah cells in a hybrid, armored vehicle being developed for military and security applications. Results have been even more encouraging than they were initially. LiFeBATT is expanding its work with several OEM customers to build a worldwide distribution network. These customers include a major automotive consulting group in the U.K., an Australian maker of luxury off-road campers, and a number of makers of E-bikes and scooters. LiFeBATT continues to explore the possibility of working with nations that are woefully short of infrastructure. Negotiations are underway with Siemens to jointly develop a system for using photovoltaic generation and battery storage to supply electricity to communities that are not currently served adequately. The IDA has continued to monitor the progress of LiFeBATT’s work to ensure that all funds are being expended wisely and that matching funds will be generated as promised.

    Full Text Available European Union requires some standards in all areas. Today, the importance of training qualified individuals which holds an important place in the development of countries increases and certain standards are adopted creating common European Union tools in the field of vocational and technical education. In this study, vocational education and training policies system and the standards adopted by the European Union are discussed. Furthermore, this study was accepted as a European Union project in 2010 and the results obtained from the Leonardo Da Vinci Life Learning European Union project called “Web Based Basic Vocational Training” between the years 2010-2012 were presented. Since the partners of these projects are Turkey, Spain and Germany, the structure of vocational education, institutions of public and private vocational education and the diplomas and certificates entitled after these educations are included. As Turkey is on its way to become a European Union member, a number of advices are presented for Turkey to reach its destination about vocational education standards that European Union has aimed. The purpose of the study is not only to be a guide for the young who want to get professional training in the countries that are European Union members or candidates about how and where to have education opportunities but also to give a chance for trainers and training managers, participating in vocational training, so as to glimpse different practices from different countries and compare these practices between the countries of European Union and their countries. The study is also very important as it has the opportunities for training managers to see if their countries' vocational education is close enough to vocational education in European Union.

  4. Individual Differences in Approach-Avoidance Aptitude: Some Clues from Research on Parkinson’s Disease

    2015-03-01

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

  5. Technological Aptitude and Applications of Leuconostoc mesenteroides Bioactive Strains Isolated from Algerian Raw Camel Milk

    2013-01-01

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

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

    2012-12-01

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

  13. Block copolymer battery separator

    Energy Technology Data Exchange (ETDEWEB)

    Wong, David; Balsara, Nitash Pervez

    2016-04-26

    The invention herein described is the use of a block copolymer/homopolymer blend for creating nanoporous materials for transport applications. Specifically, this is demonstrated by using the block copolymer poly(styrene-block-ethylene-block-styrene) (SES) and blending it with homopolymer polystyrene (PS). After blending the polymers, a film is cast, and the film is submerged in tetrahydrofuran, which removes the PS. This creates a nanoporous polymer film, whereby the holes are lined with PS. Control of morphology of the system is achieved by manipulating the amount of PS added and the relative size of the PS added. The porous nature of these films was demonstrated by measuring the ionic conductivity in a traditional battery electrolyte, 1M LiPF.sub.6 in EC/DEC (1:1 v/v) using AC impedance spectroscopy and comparing these results to commercially available battery separators.

    Kozier, K. S.; Rosinger, H. E.

    The evolution and present status of an Atomic Energy of Canada Limited program to develop a small, solid-state, passively cooled reactor power supply known as the Nuclear Battery is reviewed. Key technical features of the Nuclear Battery reactor core include a heat-pipe primary heat transport system, graphite neutron moderator, low-enriched uranium TRISO coated-particle fuel and the use of burnable poisons for long-term reactivity control. An external secondary heat transport system extracts useful heat energy, which may be converted into electricity in an organic Rankine cycle engine or used to produce high-pressure steam. The present reference design is capable of producing about 2400 kW(t) (about 600 kW(e) net) for 15 full-power years. Technical and safety features are described along with recent progress in component hardware development programs and market assessment work.

    1997-12-01

    This paper discusses the concept of battery charging stations (BCSs), designed to service rural owners of battery power sources. Many such power sources now are transported to urban areas for recharging. A BCS provides the opportunity to locate these facilities closer to the user, is often powered by renewable sources, or hybrid systems, takes advantage of economies of scale, and has the potential to provide lower cost of service, better service, and better cost recovery than other rural electrification programs. Typical systems discussed can service 200 to 1200 people, and consist of stations powered by photovoltaics, wind/PV, wind/diesel, or diesel only. Examples of installed systems are presented, followed by cost figures, economic analysis, and typical system design and performance numbers.

    According to the invention, the pore volume of the active material is increased not by having more or bigger voids but by inserting open solid particles taking up the battery acid. By inserting mechanically stable solid particles embedding into the active material or meshing with it, mechanically stable electrodes with a large pore volume are obtained. The stability of the active material, in particular of the pasty battery plate material, is least impaired if the particles have a size of 0.5 to 40 ..mu..m and if the powdered lead used for producing the paste is adapted to the shape and amount of the particles with regard to its grain size distribution. The particles may be hollow microspheres or microcapsules with acid-permeable, mechanically resistant walls.

  19. Smart battery controller for lithium sulfur dioxide batteries

    Atwater, Terrill; Bard, Arnold; Testa, Bruce; Shader, William

    1992-08-01

    Each year, the U.S. Army purchases millions of lithium sulfur dioxide batteries for use in portable electronics equipment. Because of their superior rate capability and service life over a wide variety of conditions, lithium batteries are the power source of choice for military equipment. There is no convenient method of determining the available energy remaining in partially used lithium batteries; hence, users do not take full advantage of all the available battery energy. Currently, users replace batteries before each mission, which leads to premature disposal, and results in the waste of millions of dollars in battery energy every year. Another problem of the lithium battery is that it is necessary to ensure complete discharge of the cells when the useful life of the battery has been expended, or when a hazardous condition exists; a hazardous condition may result in one or more of the cells venting. The Electronics Technology and Devices Laboratory has developed a working prototype of a smart battery controller (SBC) that addresses these problems.

    The book deals with the production, use and waste management of batteries (accumulators and primary batteries), with regard to protection of the environment. Legal, technical and medical aspects are shown. There are numerous electro-chemical systems, but only few proved to be really good in practice. Most batteries contain lead, cadmium or mercury and must therefore be eliminated in a way doing no harm to the environment. Large quantities of the above named heavy metals are today already being recovered by means of appropriate procedures. The reduction of these heavy metals in batteries is also described to be a contribution to the protection of the environment. (orig.) With 67 figs.

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

    This report summarizes the work done at Risoe DTU testing a vanadium flow battery as part of the project 'Characterisation of Vanadium Batteries' (ForskEl project 6555) with the partners PA Energy A/S and OI Electric A/S under the Danish PSO energy research program. A 15kW/120kWh vanadium battery has been installed as part of the distributed energy systems experimental facility, SYSLAB, at Risoe DTU. A test programme has been carried out to get hands-on experience with the technology, to characterize the battery from a power system point of view and to assess it with respect to integration of wind energy in the Danish power system. The battery has been in operation for 18 months. During time of operation the battery has not shown signs of degradation of performance. It has a round-trip efficiency at full load of approximately 60% (depending on temperature and SOC). The sources of the losses are power conversion in cell stacks/electrolyte, power converter, and auxiliary power consumption from pumps and controller. The response time for the battery is limited at 20kW/s by the ramp rate of the power converter. The battery can thus provide power and frequency support for the power system. Vanadium battery is a potential technology for storage based services to the power system provided investment and O and M cost are low enough and long term operation is documented. (Author)

    Full Text Available Batteries used in Implantable cardiac pacemakers-present unique challenges to their developers and manufacturers in terms of high levels of safety and reliability. In addition, the batteries must have longevity to avoid frequent replacements. Technological advances in leads/electrodes have reduced energy requirements by two orders of magnitude. Micro-electronics advances sharply reduce internal current drain concurrently decreasing size and increasing functionality, reliability, and longevity. It is reported that about 600,000 pacemakers are implanted each year worldwide and the total number of people with various types of implanted pacemaker has already crossed 3 million. A cardiac pacemaker uses half of its battery power for cardiac stimulation and the other half for housekeeping tasks such as monitoring and data logging. The first implanted cardiac pacemaker used nickel-cadmium rechargeable battery, later on zinc-mercury battery was developed and used which lasted for over 2 years. Lithium iodine battery invented and used by Wilson Greatbatch and his team in 1972 made the real impact to implantable cardiac pacemakers. This battery lasts for about 10 years and even today is the power source for many manufacturers of cardiac pacemakers. This paper briefly reviews various developments of battery technologies since the inception of cardiac pacemaker and presents the alternative to lithium iodine battery for the near future.

  11. A VRLA battery simulation model

    2004-05-01

    A valve regulated lead acid (VRLA) battery simulation model is an invaluable tool for the standby power system engineer. The obvious use for such a model is to allow the assessment of battery performance. This may involve determining the influence of cells suffering from state of health (SOH) degradation on the performance of the entire string, or the running of test scenarios to ascertain the most suitable battery size for the application. In addition, it enables the engineer to assess the performance of the overall power system. This includes, for example, running test scenarios to determine the benefits of various load shedding schemes. It also allows the assessment of other power system components, either for determining their requirements and/or vulnerabilities. Finally, a VRLA battery simulation model is vital as a stand alone tool for educational purposes. Despite the fundamentals of the VRLA battery having been established for over 100 years, its operating behaviour is often poorly understood. An accurate simulation model enables the engineer to gain a better understanding of VRLA battery behaviour. A system level multipurpose VRLA battery simulation model is presented. It allows an arbitrary battery (capacity, SOH, number of cells and number of strings) to be simulated under arbitrary operating conditions (discharge rate, ambient temperature, end voltage, charge rate and initial state of charge). The model accurately reflects the VRLA battery discharge and recharge behaviour. This includes the complex start of discharge region known as the coup de fouet. (author)

    In 1990, the California Air Resources Board has established a mandate to introduce electric vehicles in order to improve air quality in Los Angeles and other capitals. The United States Advanced Battery Consortium has been formed by the big car companies, Electric Power Research Institute (EPRI) and the Department of Energy in order to establish the requirements on EV-batteries and to support battery development. The ZEBRA battery system is a candidate to power future electric vehicles. Not only because its energy density is three-fold that of lead acid batteries (50% more than NiMH) but also because of all the other EV requirements such as power density, no maintenance, summer and winter operation, safety, failure tolerance and low cost potential are fulfilled. The electrode material is plain salt and nickel in combination with a ceramic electrolyte. The cell voltage is 2.58 V and the capacity of a standard cell is 32 Ah. Some hundred cells are connected in series and parallel to form a battery with about 300 V OCV. The battery system including battery controller, main circuit-breaker and cooling system is engineered for vehicle integration and ready to be mounted in a vehicle [J. Gaub, A. van Zyl, Mercedes-Benz Electric Vehicles with ZEBRA Batteries, EVS-14, Orlando, FL, Dec. 1997]. The background of these features are described.

    Newton, Sarah E; Moore, Gary

    2009-01-01

    Attrition is a serious issue among Bachelor of Science in Nursing (BSN) students with attrition rates around 50% nationwide. To help minimize BSN student attrition, many nursing programs use commercially available standardized nursing aptitude tests as adjuncts to scholastic aptitude data, usually operationalized as pre-nursing grade point average, to select students for admission. Little is known regarding the usefulness of scholastic and nursing aptitude data for predicting long-term retention in a BSN program and readiness for the National Council Licensure Examination-Registered Nurse (NCLEX-RN). Therefore, the purpose of this study was to describe the relationships among scholastic aptitude, nursing aptitude, BSN student attrition prior to the final semester of the curriculum, and BSN student readiness for the NCLEX-RN. This study's findings, along with other findings in the literature, suggest the need for a parsimonious explanatory model of BSN student attrition that can be used to guide admission and progression policies, and ensure that students ready for the NCLEX-RN are the ones graduating from BSN programs.

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

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

    Full Text Available Abstract Background Previous studies have identified brain areas related to cognitive abilities and personality, respectively. In this exploratory study, we extend the application of modern neuroimaging techniques to another area of individual differences, vocational interests, and relate the results to an earlier study of cognitive abilities salient for vocations. Findings First, we examined the psychometric relationships between vocational interests and abilities in a large sample. The primary relationships between those domains were between Investigative (scientific interests and general intelligence and between Realistic (“blue-collar” interests and spatial ability. Then, using MRI and voxel-based morphometry, we investigated the relationships between regional gray matter volume and vocational interests. Specific clusters of gray matter were found to be correlated with Investigative and Realistic interests. Overlap analyses indicated some common brain areas between the correlates of Investigative interests and general intelligence and between the correlates of Realistic interests and spatial ability. Conclusions Two of six vocational-interest scales show substantial relationships with regional gray matter volume. The overlap between the brain correlates of these scales and cognitive-ability factors suggest there are relationships between individual differences in brain structure and vocations.

  12. Medical sociology as a vocation.

    Science.gov (United States)

    Bosk, Charles L

    2014-12-01

    This article extends Weber's discussion of science as a vocation by applying it to medical sociology. Having used qualitative methods for nearly 40 years to interpret problems of meaning as they arise in the context of health care, I describe how ethnography, in particular, and qualitative inquiry, more generally, may be used as a tool for understanding fundamental questions close to the heart but far from the mind of medical sociology. Such questions overlap with major policy questions such as how do we achieve a higher standard for quality of care and assure the safety of patients. Using my own research, I show how this engagement takes the form of showing how simple narratives of policy change fail to address the complexities of the problems that they are designed to remedy. I also attempt to explain how I balance objectivity with a commitment to creating a more equitable framework for health care. © American Sociological Association 2014.

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

    Science.gov (United States)

    Ely, Jane Alice

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

    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 estimation of vehicle battery performance is typically addressed by testing the battery under specific operation conditions by using a model to represent the test results. Approaches for representing test results range from simple statistical models to neural networks to complex, physics-based models. Basing the model on test data could be problematical when testing becomes impractical with many years life time tests. So, real time estimation of battery performance, an important problem in automotive applications, falls into this area. In vehicles it is important to know the state of charge of the batteries in order to prevent vehicle stranding and to ensure that the full range of the vehicle operation is exploited. In this paper, several battery models have studied including analytical, electrical circuits, stochastic and electro- chemical models. Valve Regulated Lead Acid “VRLA” battery has been modelled using electric circuit technique. This model is considered in the proposed Battery Monitoring System “BMS”. The proposed BMS includes data acquisition, data analysis and prediction of battery performance under a hypothetical future loads. Based on these criteria, a microprocessor based BMS prototype had been built and tested in automotive Lab,. The tests show promising results that can be used in industrial applications

    Research was conducted on two types of lithium batteries. The first is a rechargeable Li-SO2 system using an all-inorganic electrolyte. A Li/liquid cathode system was chosen to obtain a relatively high discharge rate capability over the +20 to -30 C range. The fabrication and cycling performance of research cells are described, including the preparation and physical properties of porous polytetra fluoroethylene bonded carbon electrodes. Since the low temperature performance of the standard electrolyte was unsatisfactory, studies of electrolytes containing mixed salts were made. Raman spectroscopy was used to study the species present in these electrolytes and to identify discharge products. Infrared spectroscopy was used to measure electrolyte impurities. Film growth on the LiCl was also monitored. The second battery is a Li-thionyl chloride nonrechargeable system. Research cells were fabricated containing cobalt phthalo cyanine in the carbon cathode. The cathode was heat treated at different temperatures and the effect on cell discharge rate and capacity evaluated. Commercially obtained cells were used in an investigation of a way to identify substandard cells. The study also involved electrochemical impedance spectroscopy and cell discharging at various rates. The results are discussed in terms of LiCl passivation.

    Lithium has the most negative potential and the highest mass capacity of all solid anode materials. It is the metal that allows to reach the highest mass energies in batteries when associated to a high potential cathode. The search for high performance cathodes has led to many different types of lithium batteries (transition metal oxides or sulfides, halogenides, oxi-halogenides, carbon, organic compounds etc..). These batteries can have a solid cathode (Li/CuO, Li/MnO{sub 2}, Li/CF{sub x}, etc..), or a liquid cathode (Li/SOCl{sub 2}, Li/SO{sub 2}, etc..) and in some cases they can have also a solid electrolyte, but not all types of lithium battery led to important industrial fabrication. The increasing use of lithium batteries is linked with the development of portable equipments for which, the compactness of the energy source is a key point. This article examines only the lithium batteries that have been the object of a significant industrial fabrication: lithium-sulfur dioxide, lithium-thionyl chloride, lithium-manganese dioxide, lithium-copper oxide, lithium-carbon fluoride, lithium-iron disulfide, other types of lithium batteries.

  6. The European Dimensions of Vocational Training

    Full Text Available The research examined the connection between vocational education, training and the world of work, and the social situation in Hungary in a European outlook. The accentual issues of the analysis disclosing the problem are: youth unemployment, the tendencies of secondary vocational education, proportions of enrollment and the features of training tendencies, the growing number of early dropouts, the effect of family background on student performance. This work tried to find the answer to the question: What variations have the changes in the regulations of vocational training, encouraging dual education brought on in the connection between trainers and work places? The research did not prove that the central vocational training system would be more effective than a varied, flexible, permeable, transparent decentralized operation with parts built on each other. The introduction of the complex exam overshadowed the evaluation of the competency areas, and fits less to the modularity of the framework curricula. With the legal regulation of vocational training in force the modular system has become a formality. Taking prior knowledge into account has become more difficult. The efficiency of professional structural decisions is questionable, it has not triggered the extension of employment among career starters, and does not mean a guarantee of finding a job either. Creating the motivation of economic role players may bring on steps forward to take up bigger tasks in vocational training. The research has confirmed the importance of improving the basic competency areas when planning vocational training, of life-long learning, of practice orientation, and also of the continuous connection with the labor market.

    Over the past decade, there has been growth in the delivery of vocational rehabilitation services globally, as countries seek to control disability-related expenditure, yet there has been minimal research outside the United States on competencies required to work in this area. This study reports on research conducted in Australia to determine current job function and knowledge areas in terms of their importance and frequency of use in the provision of vocational rehabilitation. A survey comprising items from the Rehabilitation Skills Inventory-Amended and International Survey of Disability Management was completed by 149 rehabilitation counselors and items submitted to factor analysis. T-tests and analyses of variance were used to determine differences between scores of importance and frequency and differences in scores based on work setting and professional training. Six factors were identified as important and frequently used: (i) vocational counseling, (ii) professional practice, (iii) personal counseling, (iv) rehabilitation case management, (v) workplace disability case management, and (vi) workplace intervention and program management. Vocational counseling, professional practice and personal counseling were significantly more important and performed more frequently by respondents in vocational rehabilitation settings than those in compensation settings. These same three factors were rated significantly higher in importance and frequency by those with rehabilitation counselor training when compared with those with other training. In conclusion, although 'traditional' knowledge and skill areas such as vocational counseling, professional practice, and personal counseling were identified as central to vocational rehabilitation practice in Australian rehabilitation agencies, mean ratings suggest a growing emphasis on knowledge and skills associated with disability management practice.
