Sample records for abilities

  1. Human abilities.

    Sternberg, R J; Kaufman, J C

    1998-01-01

    This chapter reviews recent literature, primarily from the 1990s, on human abilities. The review opens with a consideration of the question of what intelligence is, and then considers some of the major definitions of intelligence, as well as implicit theories of intelligence around the world. Next, the chapter considers cognitive approaches to intelligence, and then biological approaches. It proceeds to psychometric or traditional approaches to intelligence, and then to broad, recent approaches. The different approaches raise somewhat different questions, and hence produce somewhat different answers. They have in common, however, the attempt to understand what kinds of mechanisms lead some people to adapt to, select, and shape environments in ways that match particularly well the demands of those environments.

  5. Cognitive ability beyond IQ

    Danner, Daniel

    2011-01-01

    The present thesis investigates cognitive performance measures beyond IQ. I investigated the psychometric properties of implicit learning variables and dynamic decision making variables and their relation with general intelligence and professional success. The results suggest that dynamic decision making and implicit learning are substantially related with general intelligence and fit well into a hierarchical model of cognitive abilities. Furthermore, general intelligence is the best predicto...

  6. Music and nonmusical abilities.

    Schellenberg, E G

    2001-06-01

    Reports that exposure to music causes benefits in nonmusical domains have received widespread attention in the mainstream media. Such reports have also influenced public policy. The so-called "Mozart effect" actually refers to two relatively distinct phenomena. One concerns short-term increases in spatial abilities that are said to occur from listening to music composed by Mozart. The other refers to the possibility that formal training in music yields nonmusical benefits. A review of the relevant findings indicates that the short-term effect is small and unreliable. Moreover, when it is evident, it can be explained by between-condition differences in the listener's mood or levels of cognitive arousal. By contrast, the effect of music lessons on nonmusical aspects of cognitive development is still an open question. Several studies have reported positive associations between formal music lessons and abilities in nonmusical (e.g., linguistic, mathematical, and spatial) domains. Nonetheless, compelling evidence for a causal link remains elusive. PMID:11458841

  7. Neurocysticercosis: Work ability evaluation

    Milovanović Aleksandar

    2008-01-01

    Full Text Available Neurocysticercosis is the term used for human CNS involvement with T. solium cysts. Intraparenchymal cerebral cysts usually enlarge slowly, causing minimal or no symptoms, until years or decades after the onset of infection. Clinical manifestations vary from focal or generalized seisures to sensomotor deficits, intellectual impairment, psychiatric disorders and symptoms of elevated intracranial pressure. Work ability was evaluated in 12 patients treated for cysticercosis during 2005 and 2006. In all patient examinations for NCC were conducted in regional health centers, and all were referred to a hospital for further diagnosis and therapy. Diagnosis was made by the following clinical criteria: neurological disorder, CT and / or MRI typical findings, followed by the test for specific antibodies. We evaluated the period from the first complaints that could be connected with the diagnosis to the moment when diagnosis was made, and severity of symptoms like vertigo, headache, vision disorders and unconsciousness. Considering neurocysticercosis as a slowly progressing infection of the CNS, with an evolution period of more than several years, and the mean period of unrecognized complaints of 28 months, we suggest that all of neurological or psychiatric complaints in our surroundings, specially where breeding of pigs is widely spread, should be evaluated for cysticercosis. .

  10. Historical Evolution of Spatial Abilities

    A. Ardila

    1993-01-01

    Full Text Available Historical evolution and cross-cultural differences in spatial abilities are analyzed. Spatial abilities have been found to be significantly associated with the complexity of geographical conditions and survival demands. Although impaired spatial cognition is found in cases of, exclusively or predominantly, right hemisphere pathology, it is proposed that this asymmetry may depend on the degree of training in spatial abilities. It is further proposed that spatial cognition might have evolved in a parallel way with cultural evolution and environmental demands. Contemporary city humans might be using spatial abilities in some new, conceptual tasks that did not exist in prehistoric times: mathematics, reading, writing, mechanics, music, etc. Cross-cultural analysis of spatial abilities in different human groups, normalization of neuropsychological testing instruments, and clinical observations of spatial ability disturbances in people with different cultural backgrounds and various spatial requirements, are required to construct a neuropsychological theory of brain organization of spatial cognition.

  11. Individual differences in auditory abilities.

    Kidd, Gary R; Watson, Charles S; Gygi, Brian

    2007-07-01

    Performance on 19 auditory discrimination and identification tasks was measured for 340 listeners with normal hearing. Test stimuli included single tones, sequences of tones, amplitude-modulated and rippled noise, temporal gaps, speech, and environmental sounds. Principal components analysis and structural equation modeling of the data support the existence of a general auditory ability and four specific auditory abilities. The specific abilities are (1) loudness and duration (overall energy) discrimination; (2) sensitivity to temporal envelope variation; (3) identification of highly familiar sounds (speech and nonspeech); and (4) discrimination of unfamiliar simple and complex spectral and temporal patterns. Examination of Scholastic Aptitude Test (SAT) scores for a large subset of the population revealed little or no association between general or specific auditory abilities and general intellectual ability. The findings provide a basis for research to further specify the nature of the auditory abilities. Of particular interest are results suggestive of a familiar sound recognition (FSR) ability, apparently specialized for sound recognition on the basis of limited or distorted information. This FSR ability is independent of normal variation in both spectral-temporal acuity and of general intellectual ability. PMID:17614500

  20. Numerical ability predicts mortgage default.

    Gerardi, Kristopher; Goette, Lorenz; Meier, Stephan

    2013-07-01

    Unprecedented levels of US subprime mortgage defaults precipitated a severe global financial crisis in late 2008, plunging much of the industrialized world into a deep recession. However, the fundamental reasons for why US mortgages defaulted at such spectacular rates remain largely unknown. This paper presents empirical evidence showing that the ability to perform basic mathematical calculations is negatively associated with the propensity to default on one's mortgage. We measure several aspects of financial literacy and cognitive ability in a survey of subprime mortgage borrowers who took out loans in 2006 and 2007, and match them to objective, detailed administrative data on mortgage characteristics and payment histories. The relationship between numerical ability and mortgage default is robust to controlling for a broad set of sociodemographic variables, and is not driven by other aspects of cognitive ability. We find no support for the hypothesis that numerical ability impacts mortgage outcomes through the choice of the mortgage contract. Rather, our results suggest that individuals with limited numerical ability default on their mortgage due to behavior unrelated to the initial choice of their mortgage. PMID:23798401

  5. Teachers of high ability pupils

    Cándido Genovard

    2010-04-01

    Full Text Available In this article we analyze the characteristics of gifted and talented students’ expert teachers. The subject background and the specific proprieties of the instructional process to meet gifted students’ educational needs are analyzed. The value of teacher-student interactions and of teaching and learning styles are highlighted. Also, we include different action guidelines and instructional resources to use in the classroom to teach these students. There is not an ideal teacher for high ability students. However, teachers must know what the teaching-learning processes are and how these work, and the diverse psychological, content and contextual variables involved in such processes.

  6. Low intelligence and special abilities.

    O'Connor, N; Hermelin, B

    1988-07-01

    In summary, our research enables us to conclude that specific talents are found in people who differ widely in general intelligence levels and such talents should therefore be regarded as at least partly intelligence-independent. However, between normal and mentally handicapped populations and even within the idiot savant group, general cognitive capacity plays some part in determining the manner in which talents manifest themselves. Idiot savant special abilities can neither be regarded as the sole consequence of practice and training, nor are such skills based only on an efficient rote memory. Instead, idiots savants use strategies which are founded on the deduction and application of rules governing the material upon which their special ability operates. They also generate novel or new examples of such rule based structures just as we do in our use of language. Because of the much greater prevalence of idiots savants in the autistic than in the mentally handicapped population, some characteristic common to both autism and specific giftedness might be assumed. An obsessional pre-occupation with a limited section of the environment might be a common factor to both. It may be this rather than autism itself which is relevant to the idiot savant phenomenon.

  7. High Ability and Learner Characteristics

    Huda Hindal

    2013-01-01

    Full Text Available The outstandingly able learner has been conceptualised, in terms of test and examination performance, as the learner showing superior academic performance which is markedly better than that of peers and in ways regarded as of value by wider society. In Kuwait, such superior examination performance leads to a classification regarded as being ‘gifted’. This study looks at the inter-correlations between performance in various subjects in examinations and then considers how examination performance correlates with measures of working memory capacity, extent of field dependency, extent of divergency and visual-spatial abilities. A very large sample of grade 7 Kuwaiti students (aged ~13 was involved, the sample being selected in such a way that it contained a high proportion of those regarded as ‘gifted’ under the procedures used in Kuwait. While specific learner characteristics have been related to examination performance, this study brings four different characteristics together to gain a picture of the way these characteristics may be seen in those who perform extremely well in examinations. Principal components analysis using varimax rotation, was used to look at the examination data and one factor accounted for 87% of the variance. A consideration of the examination papers led to the conclusion that the national examinations tested only recall-recognition. It was also found that those who performed best in all six subjects tended to be those who are highly divergent and strongly visual-spatial as well as those tending to have higher working memory capacities and being more field independent. The inter-correlations between the various learner characteristics are explained in terms of the way the brain is known to process information. The implications of the findings for assessment and for the way high ability is considered are discussed.

It can be surprising, in this context, to learn that most of what is known about cognitive ability variation across individuals concerns the broadest of all cognitive abilities; an ability referred to as general intelligence, general mental ability, or just g. In contrast, our knowledge of specific abilities, those that correlate little with g, is severely constrained. Here, we draw upon our experience investigating an exceptionally specific ability, face recognition, to make the case that many specific abilities could easily have been missed. In making this case, we derive key insights from earlier false starts in the measurement of face recognition’s variation across individuals, and we highlight the convergence of factors that enabled the recent discovery that this variation is specific. We propose that the case of face recognition ability illustrates a set of tools and perspectives that could accelerate fruitful work on specific cognitive abilities. By revealing relatively independent dimensions of human ability, such work would enhance our capacity to understand the uniqueness of individual minds. PMID:25346673

  18. Age Changes in Subjective Work Ability

    Solem, Per Erik

    2009-02-01

    Full Text Available This article explores the influence of psychosocial work environment on age-related subjective changes in work ability and discusses differences between work ability and job performance. The results show age and physical health to be strong predictors of subjective decline in work ability. The age effect is independent of age-associated declining health. It is not clear what it is about age that produces the subjective decline in work ability. While primary age changes may produce decline, stereotypes and self-stereotypes about ageing may also be important. Among psychosocial factors, options for learning and problems at work are robust predictors of subjective changes in work ability. One practical consequence is to ensure learning opportunities for workers, even for workers approaching retirement age. By giving learning opportunities to senior workers, subjective work ability may be maintained, and competence acquired through learning may in a direct way support stability or improvements in job performance.

    Recent experimental studies suggest that risk aversion is negatively related to cognitive ability. In this paper we report evidence that this relation might be spurious. We recruit a large subject pool drawn from the general Danish population for our experiment. By presenting subjects with choice...... tasks that vary the bias induced by random choices, we are able to generate both negative and positive correlations between risk aversion and cognitive ability. Structural estimation allowing for heterogeneity of noise yields no significant relation between risk aversion and cognitive ability.

  16. Host country language ability and expatriate adjustment

    Selmer, Jan; Lauring, Jakob

    2015-01-01

    Research has shown that expatriates’ host country language ability is positively associated with their adjustment. But does the advantage of expatriates’ language ability depend on the difficulty of the host language? To examine this issue, data were collected from expatriates in two European...... countries, one with an easy, relatively simple language and the other with a difficult, highly complex language. Consistent with Goal-Setting Theory, results indicated a relative advantage of expatriates’ language ability in terms of their adjustment in the host country with the difficult language as...... opposed to the host country with an easy language....

  17. Cognitive Ability, Principled Reasoning and Political Tolerance

    Hebbelstrup Rye Rasmussen, Stig; Nørgaard, Asbjørn Sonne

    Individuals are not equally politically tolerant. To explain why, individual differences in emotions and threat have received much scholarly attention in recent years. However, extant research also shows that psychological dispositions, habitual cognitive styles, ideological orientation and...... ‘principled reasoning’ influence political tolerance judgments. The extent to which cognitive ability plays a role has not been entertained even if the capacity to think abstractly, comprehend complex ideas and apply abstract ideas to concrete situations is inherent to both principled tolerance judgment and...... cognitive ability. Cognitive ability, we argue and show, adds to the etiology of political tolerance. In Danish and American samples cognitive ability strongly predicts political tolerance after taking habitual cognitive styles (as measured by personality traits), education, social ideology, and feelings of...

  18. Spatial Ability And Learning To Program

    Sue Jones

    2008-01-01

    Full Text Available Results in introductory computer programming modules are often disappointing, and various individual differences have been found to be relevant. This paper reviews work in this area, with particular reference to the effect of a student's spatial ability. Data is presented on a cohort of 49 students enrolled on an MSc in Information Technology course at a university in the UK. A measure was taken of their mental rotation ability, and a questionnaire administered that focused on their previous academic experience, and expectations relating to the introductory computer programming module they were studying. The results showed a positive correlation between mental rotation ability and success in the module (r = 0.48. Other factors, such as confidence level, expected success, and programming experience, were also found to be important. These results are discussed in relation to the accessibility of programming to learners with low spatial ability.

  6. Development of Writing Ability in English

    赵光存

    2009-01-01

    The Guiding principle for junior English teaching points out: "The aim of junior English teaching is to give the students basic training on how to listen, speak, read and write, to cultivate the students' primary ability of using English."[1]Therefore, writing in English is one of the most important contents and requirements of junior English teaching. Since 1998, the junior students have been required to demonstrate their writing ability by writing an 80-word passage, which should be very accurate, coherent, and fluent.So "the middle school teachers must encourage the students to learn to make simple sentences with the vocabulary, grammar, sentence patterns and to write simple passages, letters, e-mails, notes, notices after the styles and models which have been learned." [2] English, as a most useful language and a most widely used communication means, is very important. The students must acquire the ability of speaking and writing and their all-round ability should be developed.So I write this thesis to discuss and make a research on how to develop and improve the junior students' writing ability in English.

  7. Paramedics’ Ability to Perform Drug Calculations

    Eastwood, Kathyrn J

    2009-11-01

    Full Text Available Background: The ability to perform drug calculations accurately is imperative to patient safety. Research into paramedics’ drug calculation abilities was first published in 2000 and for nurses’ abilities the research dates back to the late 1930s. Yet, there have been no studies investigating an undergraduate paramedic student’s ability to perform drug or basic mathematical calculations. The objective of this study was to review the literature and determine the ability of undergraduate and qualified paramedics to perform drug calculations.Methods: A search of the prehospital-related electronic databases was undertaken using the Ovid and EMBASE systems available through the Monash University Library. Databases searched included the Cochrane Central Register of Controlled Trials (CENTRAL, MEDLINE, CINAHL, JSTOR, EMBASE and Google Scholar, from their beginning until the end of August 2009. We reviewed references from articles retrieved.Results: The electronic database search located 1,154 articles for review. Six additional articles were identified from reference lists of retrieved articles. Of these, 59 were considered relevant. After reviewing the 59 articles only three met the inclusion criteria. All articles noted some level of mathematical deficiencies amongst their subjects.Conclusions: This study identified only three articles. Results from these limited studies indicate a significant lack of mathematical proficiency amongst the paramedics sampled. A need exists to identify if undergraduate paramedic students are capable of performing the required drug calculations in a non-clinical setting.[WestJEM. 2009;10:240-243.

    1997-12-31

    The purpose of this study was to identify methods for improving the construct ability of nuclear power plants. This study reviewed several references of current construction practices of domestic and overseas nuclear plants in order to identify potential methods for improving construct ability. The identified methods for improving construct ability were then evaluated based on the applicability to domestic nuclear plant construction. The selected methods are expected to reduce the construction period, improve the quality of construction, cost, safety, and productivity. Selection of which methods should be implemented will require further evaluation of construction modifications, design changes, contract revisions. Among construction methods studied, platform construction methods can be applied through construction sequence modification without significant design changes, and Over the Top construction method of the NSSS, automatic welding of RCL pipes, CLP modularization, etc., are considered to be applied after design modification and adjustment of material lead time.

By use of a novel longitudinal dataset we are able to condition on early cognitive ability to account for selection into non-compulsory schooling when estimating the effect on cognitive ability at age 20. OLS estimates indicate that one year of schooling increases IQ by 2.8–3.5 points (about 0.2 standard deviations). When family income per family member and teacher evaluations of the individuals at age...

  12. Musical Activity Tunes Up Absolute Pitch Ability

    Dohn, Anders; Garza-Villarreal, Eduardo A.; Ribe, Lars Riisgaard; Wallentin, Mikkel; Vuust, Peter

    2014-01-01

    Absolute pitch (AP) is the ability to identify or produce pitches of musical tones without an external reference. Active AP (i.e., pitch production or pitch adjustment) and passive AP (i.e., pitch identification) are considered to not necessarily coincide, although no study has properly compared......, we found that APs generally undershoot when adjusting musical pitch, a tendency that decreases when musical activity increases. Finally, APs are less accurate when adjusting the pitch to black key targets than to white key targets. Hence, AP ability may be partly practice-dependent and we speculate...

  1. Development of Network Synchronization Predicts Language Abilities.

    Doesburg, Sam M; Tingling, Keriann; MacDonald, Matt J; Pang, Elizabeth W

    2016-01-01

    Synchronization of oscillations among brain areas is understood to mediate network communication supporting cognition, perception, and language. How task-dependent synchronization during word production develops throughout childhood and adolescence, as well as how such network coherence is related to the development of language abilities, remains poorly understood. To address this, we recorded magnetoencephalography while 73 participants aged 4-18 years performed a verb generation task. Atlas-guided source reconstruction was performed, and phase synchronization among regions was calculated. Task-dependent increases in synchronization were observed in the theta, alpha, and beta frequency ranges, and network synchronization differences were observed between age groups. Task-dependent synchronization was strongest in the theta band, as were differences between age groups. Network topologies were calculated for brain regions associated with verb generation and were significantly associated with both age and language abilities. These findings establish the maturational trajectory of network synchronization underlying expressive language abilities throughout childhood and adolescence and provide the first evidence for an association between large-scale neurophysiological network synchronization and individual differences in the development of language abilities.

    Bhatara, Anjali; Laukka, Petri; Boll-Avetisyan, Natalie; Granjon, Lionel; Anger Elfenbein, Hillary; Bänziger, Tanja

    2016-01-01

    The present study examines the effect of language experience on vocal emotion perception in a second language. Native speakers of French with varying levels of self-reported English ability were asked to identify emotions from vocal expressions produced by American actors in a forced-choice task, and to rate their pleasantness, power, alertness and intensity on continuous scales. Stimuli included emotionally expressive English speech (emotional prosody) and non-linguistic vocalizations (affect bursts), and a baseline condition with Swiss-French pseudo-speech. Results revealed effects of English ability on the recognition of emotions in English speech but not in non-linguistic vocalizations. Specifically, higher English ability was associated with less accurate identification of positive emotions, but not with the interpretation of negative emotions. Moreover, higher English ability was associated with lower ratings of pleasantness and power, again only for emotional prosody. This suggests that second language skills may sometimes interfere with emotion recognition from speech prosody, particularly for positive emotions. PMID:27253326

  14. Quantile forecast discrimination ability and value

    Bouallegue, Zied Ben; Friederichs, Petra

    2015-01-01

    While probabilistic forecast verification for categorical forecasts is well established, some of the existing concepts and methods have not found their equivalent for the case of continuous variables. New tools dedicated to the assessment of forecast discrimination ability and forecast value are introduced here, based on quantile forecasts being the base product for the continuous case (hence in a nonparametric framework). The relative user characteristic (RUC) curve and the quantile value plot allow analysing the performance of a forecast for a specific user in a decision-making framework. The RUC curve is designed as a user-based discrimination tool and the quantile value plot translates forecast discrimination ability in terms of economic value. The relationship between the overall value of a quantile forecast and the respective quantile skill score is also discussed. The application of these new verification approaches and tools is illustrated based on synthetic datasets, as well as for the case of global...

  15. Giving Devices the Ability to Exercise Reason

    Thomas Keeley

    2008-10-01

    Full Text Available One of the capabilities that separates humans from computers has been the ability to exercise "reason / judgment". Computers and computerized devices have provided excellent platforms for following rules. Computer programs provide the scripts for processing the rules. The exercise of reason, however, is more of an image processing function than a function composed of a series of rules. The exercise of reason is more right brain than left brain. It involves the interpretation of information and balancing inter-related alternatives. This paper will discuss a new way to define and process information that will give devices the ability to exercise human-like reasoning and judgment. The paper will discuss the characteristics of a "dynamic graphical language" in the context of addressing judgment, since judgment is often required to adjust rules when operating in a dynamic environment. The paper will touch on architecture issues and how judgment is integrated with rule processing.

    2010-01-01

    Do chief executive officers (CEOs) really matter? Do cross-sectional differences in firm performance and CEO pay reflect differences in CEO ability? Examining CEO departures over 1992-2002, we first find that the stock price reaction upon departure is negatively related to the firm's prior performance and to the CEO's prior pay. Second, the CEO's subsequent labor market success is greater if the firm's predeparture performance is better, the prior pay is higher, and the stock market's reactio...

  5. Nationalism, cognitive ability, and interpersonal relations

    Corneo, Giacomo

    2010-01-01

    Interpersonal relations are shaped by the judgements associated with the social categories that individuals perceive in their social contacts. I develop a model of how those judgments form based on a theory of symbolic values. The model depicts the interaction between two values, one associated with an inherited ethnic trait (nationality) and one with an endogenous achievement trait (income). Individuals with lower cognitive ability are predicted to invest more value on nationalism and to hav...

  7. Spatial Ability Development in the Geosciences

    Baldwin, T. K.; Hall-Wallace, M. K.

    2003-12-01

    We designed an experiment to evaluate change in students' spatial skills as a result of completing an earth science course. Our test subjects included high school students in earth science classes, college level non-science majors enrolled in large enrollment introductory geoscience courses and introductory level geoscience majors. They also varied as to whether their course had a hand-on laboratory experience or used supplemental Geographic Information System (GIS) based activities. We measured all students' ability to mentally rotate three-dimensional objects and to construct a three-dimensional object from a two-dimensional representation before and after taking the earth science course. Results show an improvement in spatial skills for all groups after completing the science course. We also observed a consistent improvement in spatial skills overall from high school level science to courses for majors, which is possibly related to their increased exposure to science. A subgroup of the test subjects among both high school and the college non-science majors completed supplementary GIS activities. The GIS implementation at the high school level was more extensive and resulted in significant improvements in both categories of spatial ability. At the college level, the non-science majors that used the GIS curriculum showed no significant difference from those that did not, probably because the time spent on the curriculum was too short. At the college level, the geoscience majors had nearly three times the improvement of non-science majors in both categories of spatial ability. This can most likely be attributed to hands-on, weekly laboratory experiences, which were not part of the course for non-science majors. Students choosing science majors typically have much higher spatial skills than the average first or second year non-science major, however there were large variations in spatial ability within all groups. These results suggest that we evaluate teaching

  8. Giving Devices the Ability to Exercise Reason

    Thomas Keeley

    2008-01-01

    One of the capabilities that separates humans from computers has been the ability to exercise "reason / judgment". Computers and computerized devices have provided excellent platforms for following rules. Computer programs provide the scripts for processing the rules. The exercise of reason, however, is more of an image processing function than a function composed of a series of rules. The exercise of reason is more right brain than left brain. It involves the interpretation of information an...

  10. Implicit theories and ability emotional intelligence.

    Cabello, Rosario; Fernández-Berrocal, Pablo

    2015-01-01

    Previous research has shown that people differ in their implicit theories about the essential characteristics of intelligence and emotions. Some people believe these characteristics to be predetermined and immutable (entity theorists), whereas others believe that these characteristics can be changed through learning and behavior training (incremental theorists). The present study provides evidence that in healthy adults (N = 688), implicit beliefs about emotions and emotional intelligence (EI) may influence performance on the ability-based Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT). Adults in our sample with incremental theories about emotions and EI scored higher on the MSCEIT than entity theorists, with implicit theories about EI showing a stronger relationship to scores than theories about emotions. Although our participants perceived both emotion and EI as malleable, they viewed emotions as more malleable than EI. Women and young adults in general were more likely to be incremental theorists than men and older adults. Furthermore, we found that emotion and EI theories mediated the relationship of gender and age with ability EI. Our findings suggest that people's implicit theories about EI may influence their emotional abilities, which may have important consequences for personal and professional EI training. PMID:26052309

  12. Estimation abilities of large numerosities in Kindergartners

    2013-08-01

    Full Text Available The approximate number system (ANS is thought to be a building block for the elaboration of formal mathematics. However, little is known about how this core system develops and if it can be influenced by external factors at a young age (before the child enters formal numeracy education. The purpose of this study was to examine numerical magnitude representations of 5 to 6 year old children at 2 different moments of Kindergarten considering children’s early number competence as well as schools’ socio-economic index (SEI. This study investigated estimation abilities of large numerosities using symbolic and non-symbolic output formats (8 to 64. In addition, we assessed symbolic and non-symbolic early number competence (1 to 12 at the end of the 2nd (N = 42 and the 3rd (N = 32 kindergarten grade. By letting children freely produce estimates we observed surprising estimation abilities at a very young age (from 5 year on extending far beyond children’s symbolic explicit knowledge. Moreover, the time of testing has an impact on the ANS accuracy since 3rd kindergarteners were more precise in both estimation tasks. Additionally, children who presented better exact symbolic knowledge were also those with the most refined ANS. However, this was true only for 3rd kindergarteners who were a few months from receiving math instructions. In a similar vein, higher SEI positively impacted only the oldest children’s estimation abilities whereas it played a role for exact early number competences already in 2nd and 3rd graders. Our results support the view that approximate numerical representations are linked to exact number competence in young children before the start of formal math education and might thus serve as building blocks for mathematical knowledge. Since this core number system was also sensitive to external components such as the SEI this implies that it can most probably be targeted and refined through specific educational strategies from

    2015-01-01

    With the opening-up of China,English teaching has been getting more and more attention.People are enthusiastic about learning English.As a result,English teaching and reform are coming to a turning point,which predicts a bright future in English education in China.Now,a 9-year voluntary education program is put forward in China.A Standard English course is being used to replace the former teaching outline.The new standard adopts the international system according to which English language education is divided into 9 levels.This has changed the old style of teaching,which attaches importance to grammar and vocabulary.Adopting the new standard helps to develop the senior students’ability to use English in their daily life,by focusing on arousing their interest,and encouraging their participation. The new method will place less stress on“reading and writing”,in favor of“listening”and“speaking”.So now,speaking is getting more and more important in middle high school English teaching. This paper discuss how to improve students’speaking ability and expound the theme through three aspects as follows:⒈The importance of speaking.⒉Some barriers in the process of speaking communication.⒊Essential methods for improving students’speaking ability. The issue will be discussed from the perspective of a teacher of English in junior middle school and a possible conclusion will bereached with the help of some theoretical and practical support.

  18. An exploration of the uncertainty relation satisfied by BP network learning ability and generalization ability

    LI Zuoyong; PENG Lihong

    2004-01-01

    This paper analyses the intrinsic relationship between the BP network learning ability and generalization ability and other influencing factors when the overfit occurs, and introduces the multiple correlation coefficient to describe the complexity of samples; it follows the calculation uncertainty principle and the minimum principle of neural network structural design, provides an analogy of the general uncertainty relation in the information transfer process, and ascertains the uncertainty relation between the training relative error of the training sample set, which reflects the network learning ability,and the test relative error of the test sample set, which represents the network generalization ability; through the simulation of BP network overfit numerical modeling test with different types of functions, it is ascertained that the overfit parameter q in the relation generally has a span of 7×10-3 to 7 × 10-2; the uncertainty relation then helps to obtain the formula for calculating the number of hidden nodes of a network with good generalization ability under the condition that multiple correlation coefficient is used to describe sample complexity and the given approximation error requirement is satisfied;the rationality of this formula is verified; this paper also points out that applying the BP network to the training process of the given sample set is the best method for stopping training that improves the generalization ability.

  1. Development of cognitive abilities as educational goal

    Milanović-Nahod Slobodanka S.

    2004-01-01

    Full Text Available The present paper sets out to consider cognitive abilities development depending on learning and educational goals. Three standpoints and their effects on the quality of cognition are opposed: determination of tasks and goals beforehand, non-determination of tasks and goals beforehand, and alternative models where general and specific goals are planned specification being left to curriculum executors. Thereafter, consideration is given to the learning theories where it is insisted either upon learner’s individual activities or upon planning of learning context which contains interrelations between teachers, learners and contents. Emphasis is placed on a discrepancy between theoretical ideas providing good reasons for independently constructed knowledge evaluation, on the one hand, and school practice that commonly does not attribute great importance to such knowledge on the other hand. How the development of cognitive abilities will proceed in teaching depends largely on teachers themselves - their understanding of tasks and goals, qualifications they possess for school subject they teach manner of executing instruction, and familiarity with student personality needs. We can accept the standpoint that we need the theory focusing straight on education, but must be broad enough to embrace both individual and contextual perspective as well as activities of both teachers and students.

  2. Phishing IQ Tests Measure Fear, Not Ability

    Anandpara, Vivek; Dingman, Andrew; Jakobsson, Markus; Liu, Debin; Roinestad, Heather

    We argue that phishing IQ tests fail to measure susceptibility to phishing attacks. We conducted a study where 40 subjects were asked to answer a selection of questions from existing phishing IQ tests in which we varied the portion (from 25% to 100%) of the questions that corresponded to phishing emails. We did not find any correlation between the actual number of phishing emails and the number of emails that the subjects indicated were phishing. Therefore, the tests did not measure the ability of the subjects. To further confirm this, we exposed all the subjects to existing phishing education after they had taken the test, after which each subject was asked to take a second phishing test, with the same design as the first one, but with different questions. The number of stimuli that were indicated as being phishing in the second test was, again, independent of the actual number of phishing stimuli in the test. However, a substantially larger portion of stimuli was indicated as being phishing in the second test, suggesting that the only measurable effect of the phishing education (from the point of view of the phishing IQ test) was an increased concern—not an increased ability.

  3. Induced variability for combining ability in Sorghum

    Full text: Two potential varieties of sorghum were mutagenised by using MMS. F1 seeds were produced by crossing M1 or M2 plants of the two varieties as males with the ruling male sterile line 296A as female. The mutant cross F1s were grown in the field along with control F1s. The variability in the M- derived F1 populations was higher. This was accompanied by an increase in mean yield. Dependent upon the genotypes treated with MMS, there was a greater increase in variability for grain yield or a greater increase in variability for days to flowering. The mutagen seems to have induced variability for combining ability of the two varieties of sorghum, the nature of induced variability depending upon the genotype of the variety. (author)

  6. Ontogeny of numerical abilities in fish.

    Angelo Bisazza

    Full Text Available BACKGROUND: It has been hypothesised that human adults, infants, and non-human primates share two non-verbal systems for enumerating objects, one for representing precisely small quantities (up to 3-4 items and one for representing approximately larger quantities. Recent studies exploiting fish's spontaneous tendency to join the larger group showed that their ability in numerical discrimination closely resembles that of primates but little is known as to whether these capacities are innate or acquired. METHODOLOGY/PRINCIPAL FINDINGS: We used the spontaneous tendency to join the larger shoal to study the limits of the quantity discrimination of newborn and juvenile guppies. One-day old fish chose the larger shoal when the choice was between numbers in the small quantity range, 2 vs. 3 fish, but not when they had to choose between large numbers, 4 vs. 8 or 4 vs. 12, although the numerical ratio was larger in the latter case. To investigate the relative role of maturation and experience in large number discrimination, fish were raised in pairs (with no numerical experience or in large social groups and tested at three ages. Forty-day old guppies from both treatments were able to discriminate 4 vs. 8 fish while at 20 days this was only observed in fish grown in groups. Control experiments showed that these capacities were maintained after guppies were prevented from using non numerical perceptual variables that co-vary with numerosity. CONCLUSIONS/SIGNIFICANCE: Overall, our results suggest the ability of guppies to discriminate small numbers is innate and is displayed immediately at birth while discrimination of large numbers emerges later as a result of both maturation and social experience. This developmental dissociation suggests that fish like primates might have separate systems for small and large number representation.

    The purpose of this article is to introduce some approaches to develop students' communicative ability. The authors first lypresents some problems in traditional teaching of intensive reading; e g., present vocabulary' items one by one; analyse the text sentence by sentence; the stage of teachers' teaching method is fixed, teachers usually present vocabulary in the text,then explain the text by' analyzing structure first, meaning second;teachers completely' take the charge of the class and speak a lot,they forget to involve the students' participation. Then,the paper presents the practical ways of teaching based on the learner-centered approach in classrooms to show how students' initiative is given fully play, including 1) Design some questions that will lead students into the core materials of a lesson. 2) Ask students to anticipate the content of the text judging from the title or ask students some guiding questions related to the text. 3) Working on the text by means of text analysis, ask students to find topic sentences, make sound judgment and inference, recognize denotation and connotation, understand figurative language,draw conclusions and work out the organization of the text and features of its style. 4)Create a friendly' learning environment and provide more opportunities for students to practise. Finally,the paper presents some cautions to be taken in teaching.

    Full Text Available Conjugated fatty acids (CFA have received increased interest because of their beneficial effects on human health, including preventing cancer development. Conjugated linoleic acids (CLA are such CFA, and have been reviewed extensively for their multiple biological activities. In contrast to other types of CFAs including CLA that are found at low concentrations (less than 1% in natural products, conjugated linolenic acids (CLN are the only CFAs that occur in higher quantities in natural products. Some plant seeds contain a considerably high concentration of CLN (30 to 70 wt% lipid. Our research group has screened CLN from different plant seed oils to determine their cancer chemopreventive ability. This review describes the physiological functions of CLN isomers that occur in certain plant seeds. CLN are able to induce apoptosis through decrease of Bcl-2 protein in certain human cancer cell lines, increase expression of peroxisome proliferator-activated receptor (PPAR-γ, and up-regulate gene expression of p53. Findings in our preclinical animal studies have indicated that feeding with CLN resulted in inhibition of colorectal tumorigenesis through modulation of apoptosis and expression of PPARγ and p53. In this review, we summarize chemopreventive efficacy of CLN against cancer development, especially colorectal cancer.

  18. Adjusting ability and sensibility for an accident

    Adjusting ability (technical competence) and sensibility (consciousness) are the two most important priorities any staff member of any organization should bear in mind while acting during a nuclear or radiological emergency. The discussion is aimed at the national authorities of states which do not have a major nuclear power reactor programme, and especially at the IAEA and WHO: although a decade has gone by, the lessons from the radiological accident in Goiania have not been fully learned. The events which unravelled in the fall of 1987 took the population of the city of Goiania completely by surprise: they did not comprehend what had happened and failed to grasp what measures needed to be taken, a situation which precipitated a very complex psychological reaction, coupled with discrimination. To ensure the safety of radiation sources and nuclear installations, national and international organizations should direct their efforts towards educating and training staff in developing countries who work with ionizing radiation and promoting organizational capacity. This should be done first, by improving safety qualitatively so as to better control the uses of radioactive materials in medicine, agriculture, industry and research, and secondly, by assisting countries without a major nuclear power reactor programme to develop an objective and realistic emergency response training programme.

    Full Text Available Abstract Background There is a strong need for studies evaluating tests in terms both of psychometric properties (i.e. their efficacy or ability to be helpful in reaching a diagnosis and of their cost-effectiveness (i.e. their efficiency. These data are essential for planning a correct evaluation to identify children's needs (both educational and abilitative. Methods We evaluated 58 children attending for the first time the last year of the Scuola dell'Infanzia. Parental view was obtained with Child Behaviour Check-List and Conners' Rating Scales - Revised, and family socio-economic status was evaluated using Hollingshead's Four Factor Index; teacher compiled the IPDA questionnaire; children were administered Raven's Progressive Matrices, Modified Bell Cancellation Test, BVN 5-11 (a neuropsychological battery. Results A correlational analysis was conducted using Spearman's Rho (since variables were not normally distributed. These asymptomatic children show a good global cognitive functioning, but also a deficit of attention and of Executive Functions. Some of the tests used seem more cost-effective than others and there are some redundancies in information obtained. Conclusions Our data show that there are significant correlations between different neuropsychological and behavioural measures. It is therefore possible to rationalize diagnostic protocols without a significant information reduction. A deeper analysis will require a preliminary definition of the psychometric properties of used tools.

  20. Sleep loss and "divergent" thinking ability.

    Horne, J A

    1988-12-01

    Although much is known about the impact of sleep loss on many aspects of psychological performance, the effects on divergent ("creative") thinking has received little attention. Twelve subjects went 32 h without sleep, and 12 others acted as normally sleeping controls. All subjects were assessed on the figural and verbal versions of the Torrance Tests of Creative Thinking. As compared with the control condition, sleep loss impaired performance on all test scales (e.g., "flexibility," the ability to change strategy, and "originality," generation of unusual ideas) for both versions, even on an initial 5-min test component. In an attempt at further understanding of whether these findings might be explained solely by a loss of motivation, two additional short and stimulating tests were also used--a word fluency task incorporating high incentive to do well and a challenging nonverbal planning test. Performance at these tasks was still significantly impaired by sleep loss. Increased perseveration was clearly apparent. Apparently, 1 night of sleep loss can affect divergent thinking. This contrasts with the outcome for convergent thinking tasks, which are more resilient to short-term sleep loss. PMID:3238256

  1. Children's abilities to distinguish novel languages

    Bond, Z. S.; Stockmal, Verna

    2005-04-01

    When adults hear spoken samples of a language which they do not know, they can often identify it and discriminate between languages even when produced by the same talkers. Children have much less experience making metalinguistic judgments. How do children respond to languages which they do not know? We have conducted three experiments examining the abilities of 4-year old and 8-year old children to discriminate between spoken samples of different languages produced by bilingual talkers. We constructed listening tests from 5-second phrases excerpted from fluent reading provided by the talkers. In the three experiments, we progressively simplified the response mode employed by the children as well as the cognitive load of the task. Even in the simplest version, only a third of the 4-year-olds could do the task while the 8-year old children performed above chance in all three experiments. The younger children tended to respond different more than same, as if their criterion for same was identify.

  2. Heritable differences in chemosensory ability among humans

    Newcomb Richard D

    2012-05-01

    Full Text Available Abstract The combined senses of taste, smell and the common chemical sense merge to form what we call ‘flavor.’ People show marked differences in their ability to detect many flavors, and in this paper, we review the role of genetics underlying these differences in perception. Most of the genes identified to date encode receptors responsible for detecting tastes or odorants. We list these genes and describe their characteristics, beginning with the best-studied case, that of differences in phenylthiocarbamide (PTC detection, encoded by variants of the bitter taste receptor gene TAS2R38. We then outline examples of genes involved in differences in sweet and umami taste, and discuss what is known about other taste qualities, including sour and salty, fat (termed pinguis, calcium, and the ‘burn’ of peppers. Although the repertoire of receptors involved in taste perception is relatively small, with 25 bitter and only a few sweet and umami receptors, the number of odorant receptors is much larger, with about 400 functional receptors and another 600 potential odorant receptors predicted to be non-functional. Despite this, to date, there are only a few cases of odorant receptor variants that encode differences in the perception of odors: receptors for androstenone (musky, isovaleric acid (cheesy, cis-3-hexen-1-ol (grassy, and the urinary metabolites of asparagus. A genome-wide study also implicates genes other than olfactory receptors for some individual differences in perception. Although there are only a small number of examples reported to date, there may be many more genetic variants in odor and taste genes yet to be discovered.

  14. Cognitive abilities in early adolescence: an outlook from positive psychology

    Norma Contini de González

    2015-09-01

    Full Text Available The aim of this work is to refer to social abilities in early adolescence. Personal success and social success seem to be more related to interpersonal abilities than with those cognitive abilities expressed in synthetic measures of IQ. Social abilities are also one of the major sources of self esteem and personal well-being. The concepts of social intelligence, social abilities, social competence, assertiveness and adaptative behaviour are differentiated. Social abilities are characterized. The different types of social abilities founded are described and the theories which explain those types of abilities are referred. Possible interaction between social abilities, personality and psychosocial adjustment are analyzed. Positive Psychology is defined. It is explained why the Social Abilities are part of child and adolescent’s psychological capital. It is also treated why is important to study those aspects recently mentioned in early adolescence. Opportune diagnosis of those types of adolescent resources –or their dysfunctions like aggressiveness or isolation- would allow tracing a lay out intervention programs which promote protective abilities for its development which also would help the permanence in the scholar system as a way of social inclusion. Finally, it is explained how social abilities work as a salugenic resource in early adolescence within the frame of Positive Psychology. 

  15. Integrating Hot and Cool Intelligences: Thinking Broadly about Broad Abilities

  19. Measuring Research on County Agricultural Technological Innovation Ability Index

    2011-01-01

    Taking the mechanism of technological construction guidance theory and mode which consists of "objective-construction-evaluation-construction-objective" as a starting point, on the basis of county agricultural technological innovation ability and its index definition, this paper researches the constructing system of county agricultural technological innovation ability. Firstly, on the basis of defining county agricultural technological innovation ability and the definition of index, according to the principle of purposefulness, scientificity, systematicness, integration of dynamic state and static state, integration of quantitativeness and qualitativeness and so on, we construct the multi-level measuring system of county agricultural technological innovation ability, including 4 first-level indices, namely technological innovation environment, technological innovation basis, technological innovation ability, and technological innovation efficiency; 15 second-level indices, such as technological policy, technological system mechanism, technological institution construction, ability of innovation subject, ability of industrial expansion, scale merit, technological contribution rate. Moreover, this system has 45 third-level indices. Then, by using unascertained mathematics method and AHM method, we establish the multi-level unascertained composite measuring model of county agricultural technological innovation ability index. Finally, by using the survey data of one county in Hebei Province, and the established county agricultural technological innovation ability index model, we get the county agricultural technological innovation ability index of 0.711 by calculation, that is, the innovation ability is at the intermediate level, namely the modern agricultural sub-stage. The empirical research proves the correctness and applicability of this model.

  20. Pragmatic Abilities of Children with Williams Syndrome: A Longitudinal Examination

    2012-06-01

    Full Text Available Although prior research has indicated that pragmatics is an area of particular weakness for individuals with Williams syndrome (WS, the relations among different pragmatic abilities and the relations between pragmatic ability and expressive vocabulary ability have yet to be addressed. In addition, analyses of the relations between the same type of pragmatic ability over time have not been reported. The present study was designed to address these questions. We considered the pragmatic language abilities of 14 children with WS at two time points: as 4-year-olds during a 30-minute play-session with their mothers (Time 1 and an average of 5.87 years later during a one-on-one conversation with a familiar researcher (Time 2. Children’s intellectual and expressive vocabulary abilities were assessed at both time points. Results indicated that the ability to verbally contribute information beyond what was required in response to a question was significantly related to the ability to verbally contribute new information in the absence of a question both at age 4 years and during primary school. At age 4, both the ability to pair verbalizations with eye contact (intersubjectivity and expressive vocabulary ability were related to the ability to verbally contribute information beyond what was expected within a social interaction. Finally, the ability to verbally contribute new information to a social interaction beyond what was required to answer a question and the ability to pair verbalizations with eye contact (intersubjectivity at age 4 years predicted the ability to verbally contribute new information beyond what was required to answer a question at age 9 – 12 years. The theoretical implications of our findings and the importance of early pragmatic language intervention for children who have WS are discussed.

  1. Processing of space, time, and number contributes to mathematical abilities above and beyond domain-general cognitive abilities.

    Skagerlund, Kenny; Träff, Ulf

    2016-03-01

    The current study investigated whether processing of number, space, and time contributes to mathematical abilities beyond previously known domain-general cognitive abilities in a sample of 8- to 10-year-old children (N=133). Multiple regression analyses revealed that executive functions and general intelligence predicted all aspects of mathematics and overall mathematical ability. Working memory capacity did not contribute significantly to our models, whereas spatial ability was a strong predictor of achievement. The study replicates earlier research showing that non-symbolic number processing seems to lose predictive power of mathematical abilities once the symbolic system is acquired. Novel findings include the fact that time discrimination ability was tied to calculation ability. Therefore, a conclusion is that magnitude processing in general contributes to mathematical achievement. PMID:26637947

  2. Children with Williams syndrome: Developmental trajectories for intellectual abilities, vocabulary abilities, and adaptive behavior.

    Mervis, Carolyn B; Pitts, C Holley

    2015-06-01

    To examine longitudinal trajectories of intellectual abilities, single-word vocabulary abilities, and adaptive behavior for 76 children with Williams syndrome (WS) aged 4-15 years, we compared their standard scores (SSs) at two time points approximately 3 years apart on the same standardized measures. At the group level, mean SS declined significantly for 8 of the 12 measures and showed a slight (nonsignificant) increase or decrease for 4 measures. However, for most measures significant changes in SS were found for only a small proportion of the children, with some children evidencing significant declines and a smaller proportion evidencing significant increases. Significant SS changes were most common for adaptive behavior. For all measures, the mean magnitude of SS change was smaller for older children (>7.5 years at Time 1) than for younger children (<7.5 years at Time 1). Furthermore, correlations between Time 1 and Time 2 SSs were larger for the older cohort than for the younger cohort, indicating that SS stability was greater for older children than for younger children. Although mean SSs declined for most measures, indicating that children with WS as a group were not making the expected amount of progress relative to their general population peers who earned the same SS at Time 1, there was little evidence either of regression (loss of skills) or stagnation (failure to increase raw scores). The relations of these results to those of previous smaller-sample longitudinal studies of children with WS and the implications of the findings are considered. PMID:25989316

  17. Risk Aversion Relates to Cognitive Ability: Preferences or Noise?

    Tyran, Jean-Robert Karl

    2015-01-01

    Recent experimental studies suggest that risk aversion is negatively related to cognitive ability. In this paper we report evidence that this relation might be spurious. We recruit a large subject pool drawn from the general Danish population for our experiment. By presenting subjects with choice...... tasks that vary the bias induced by random choices, we are able to generate both negative and positive correlations between risk aversion and cognitive ability. Structural estimation allowing for heterogeneity of noise yields no significant relation between risk aversion and cognitive ability. Our...... results suggest that cognitive ability is related to random decision making, rather than to risk preferences....

  6. Incremental validity of emotional intelligence ability in predicting academic achievement.

    Lanciano, Tiziana; Curci, Antonietta

    2014-01-01

    We tested the incremental validity of an ability measure of emotional intelligence (El) in predicting academic achievement in undergraduate students, controlling for cognitive abilities and personality traits. Academic achievement has been conceptualized in terms of the number of exams, grade point average, and study time taken to prepare for each exam. Additionally, gender differences were taken into account in these relationships. Participants filled in the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT), the Raven's Advanced Progressive Matrices, the reduced version of the Eysenck Personality Questionnaire, and academic achievement measures. Results showed that El abilities were positively related to academic achievement indices, such as the number of exams and grade point average; total El ability and the Perceiving branch were negatively associated with the study time spent preparing for exams. Furthermore, El ability adds a percentage of incremental variance with respect to cognitive ability and personality variables in explaining scholastic success. The magnitude of the associations between El abilities and academic achievement measures was generally higher for men than for women. Jointly considered, the present findings support the incremental validity of the MSCEIT and provide positive indications of the importance of El in students' academic development. The helpfulness of El training in the context of academic institutions is discussed. PMID:25603581

  7. Study on evaluation of cities' ability reducing earthquake disasters

    张风华; 谢礼立; 范立础

    2004-01-01

    Cities′ ability reducing earthquake disasters is a complex system involving numerous factors, moreover the re-search on evaluating cities′ ability reducing earthquake disasters relates to multi-subject, such as earthquake sci-ence, social science, economical science and so on. In this paper, firstly, the conception of cities′ ability reducingearthquake disasters is presented, and the ability could be evaluated with three basic elements - the possible seis-mic casualty and economic loss during the future earthquakes that are likely to occur in the city and its surround-ings and time required for recovery after earthquake; based upon these three basic elements, a framework, whichconsists of six main components, for evaluating city′s ability reducing earthquake disasters is proposed; then thestatistical relations between the index system and the ratio of seismic casualty, the ratio of economic loss and re-covery time are gained utilizing the cities′ prediction results of earthquake disasters which were made during theninth five-year plan; at last, the method defining the comprehensive index of cities′ ability reducing earthquakedisasters is presented. Thus the relatively comprehensive theory frame is set up. The frame can evaluate cities′ability reducing earthquake disasters absolutely and quantitatively and consequently instruct the decision-makingon reducing cities′ earthquake disasters loss.

  8. Risk Aversion Relates to Cognitive Ability: Preferences or Noise?

    Andersson, Ola; Holm, Håkan J.; Tyran, Jean-Robert Karl;

    2016-01-01

    Recent experimental studies suggest that risk aversion is negatively related to cognitive ability. In this paper we report evidence that this relation may be spurious. We recruit a large subject pool drawn from the general Danish population for our experiment. By presenting subjects with choice...... tasks that vary the bias induced by random choices, we are able to generate both negative and positive correlations between risk aversion and cognitive ability. Our results suggest that cognitive ability is related to random decision making rather than to risk preferences....

  11. Resting alpha activity predicts learning ability in alpha neurofeedback

    Wenya eNan

    2014-07-01

    Full Text Available Individuals differ in their ability to learn how to regulate the alpha activity by neurofeedback. This study aimed to investigate whether the resting alpha activity is related to the learning ability of alpha enhancement in neurofeedback and could be used as a predictor. A total of 25 subjects performed 20 sessions of individualized alpha neurofeedback in order to learn how to enhance activity in the alpha frequency band. The learning ability was assessed by three indices respectively: the training parameter changes between two periods, within a short period and across the whole training time. It was found that the resting alpha amplitude measured before training had significant positive correlations with all learning indices and could be used as a predictor for the learning ability prediction. This finding would help the researchers in not only predicting the training efficacy in individuals but also gaining further insight into the mechanisms of alpha neurofeedback.

  12. Predicting psychological symptoms: the role of perceived thought control ability.

    Peterson, Rachel D; Klein, Jenny; Donnelly, Reesa; Renk, Kimberly

    2009-01-01

    The suppression of intrusive thoughts, which have been related significantly to depressive and anxious symptoms (Blumberg, 2000), has become an area of interest for those treating individuals with psychological disorders. The current study sought to extend the findings of Luciano, Algarabel, Tomas, and Martínez (2005), who developed the Thought Control Ability Questionnaire (TCAQ) and found that scores on this measure were predictive of psychopathology. In particular, this study examined the relationship between scores on the TCAQ and the Personality Assessment Inventory. Findings suggested that individuals' perceived thought control ability correlated significantly with several dimensions of commonly-occurring psychological symptoms (e.g. anxiety) and more severe and persistent psychological symptoms (e.g. schizophrenia). Regression analyses also showed that perceived thought control ability predicted significantly a range of psychological symptoms over and above individuals' sex and perceived stress. Findings suggested that thought control ability may be an important future research area in psychological assessment and intervention. PMID:19235599

  14. Assessing Student's Ability to Solve Textbook Style Problems

    Cummings, Karen

    2015-04-01

    Can We Really Measure Problem Solving Ability? The answer to this question may depend on how we define problem solving ability. But, if we care about students' ability to solve novel textbook style problems, the answer to this question seems to be ``yes.'' In this talk I will discuss a pre-/post- instruction assessment that was recently developed to assess students' ability to solve fairly standard textbook style problems within the domains of Newton's second law, conservation of energy and conservation of momentum. The instrument is designed for large-scale use in typical university classrooms, has already been used in a variety of institutions and appears to be both valid and robust. Data collected with this instrument can help guide curricular improvements and provide important insights relevant to most departments for program review.

  18. Is playing video games related to cognitive abilities?

    Unsworth, Nash; Redick, Thomas S; McMillan, Brittany D; Hambrick, David Z; Kane, Michael J; Engle, Randall W

    2015-06-01

    The relations between video-game experience and cognitive abilities were examined in the current study. In two experiments, subjects performed a number of working memory, fluid intelligence, and attention-control measures and filled out a questionnaire about their video-game experience. In Experiment 1, an extreme-groups analysis indicated that experienced video-game players outperformed nonplayers on several cognitive-ability measures. However, in Experiments 1 and 2, when analyses examined the full range of subjects at both the task level and the latent-construct level, nearly all of the relations between video-game experience and cognitive abilities were near zero. These results cast doubt on recent claims that playing video games leads to enhanced cognitive abilities. Statistical and methodological issues with prior studies of video-game experience are discussed along with recommendations for future studies. PMID:25896420

    Full Text Available This study investigated the desirable educational background for a teacher to work with high ability/gifted students, desirable characteristics these teachers should present and conceptions on high ability/giftedness. The participants were 20 public school teachers from a city surrounding Brasilia. Of this group, ten were elementary school teachers working with initial grades and ten were undergraduate Pedagogy teachers. A qualitative approach was used and data were collected by means of a semi-structured interview. A content analysis was then conducted. In relation to the desirable educational background for a teach of high ability/gifted students, participants indicated the need of continuous training, under graduation curriculum adapted to the theme and graduation courses in the area. The desirable features for teachers of high ability/gifted students were related to personological attributes (personality traits and intellectual ability, as well as professional characteristics. The conceptions on high ability/giftedness presented by the participants were, in general, close to those found in the literature and used as reference for this study. However, there was lack of information on how to apply the theory into real practice, as well as several wrong ideas on the topic.

  16. Prospective and Retrospective Metacognitive Abilities in Rhesus Monkeys

    Jennifer Ding

    2007-06-01

    Full Text Available Metacognition refers to a knowledge of one’s own cognitive abilities and one’s aptitude to alter these abilities if necessary. Previous research from our lab shows that monkeys exhibit metacognitive abilities by accurately judging their own performance on perceptual and serial working memory tasks. The present study includes two phases during which a monkey makes retrospective and prospective judgments of confidence. In the retrospective phase of this experiment, the subject completes a recall task, and then judges his performance on the test phase by choosing from high and low-risk confidence choices. In the prospective task, the monkey makes his confidence judgment before the test, instead judging how well he learned during the study phase. An analysis of results indicates that monkeys can immediately transfer the ability to make metacognitive judgments from the serial working memory tasks in previous experiments to retrospective and prospective recall tasks in the present study. These findings underline the similarity between the non-human primate and human abilities to make confidence judgments. Further, they are the first evidence to date of a non-human primate making a prospective judgment of future performance, suggesting that the ability to use a metacognitive state to control one’s actions is not uniquely human.

    Full Text Available Abstract Background Infections by a variety of pathogens are a significant cause of morbidity and mortality during perinatal period. The susceptibility of neonates to bacterial infections has been attributed to immaturity of innate immunity. It is considered that one of the impaired mechanisms is the phagocytic function of neutrophils and monocytes. The purpose of the present study was to investigate the phagocytic ability of neonates at birth. Methods The phagocytic ability of neutrophils and monocytes of 42 neonates was determined using the Phagotest flow cytometry method, that assesses the intake of E. Coli by phagocytes, in cord blood and in peripheral blood 3 days after birth. Fifteen healthy adults were included in the study as controls. Results The phagocytic ability of neutrophils in the cord blood of neonates was significantly reduced compared to adults. The 3rd postnatal day the reduction of phagocytic ability of neutrophils was no longer significant compared to adults. The phagocytic ability of monocytes did not show any difference from that of adults either at birth or the 3rd postnatal day. Conclusions Our findings indicate that the intake of E. Coli by phagocytes is impaired at birth in both preterm and full term neonates compared to adults. This defect is transient, with the phagocytic ability in neonates reaching that of the adults 3 days after birth.

    Full Text Available This paper presents the results of research regarding the mnemonic abilities of primary school children with developmental delays. Empirical studies of impaired mental development offer an opportunity to elucidate the psychological mechanisms underlying the process of normal development and enable us to consider at a micro level the formation of mental processes in ontogeny, which would, under normal conditions, be nondescript and not always amenable to psychological analysis. The research addresses an experimental investigation of productivity and qualitative characteristics of mnemonic abilities among primary school students with developmental delays. V.D. Shadrikov’s Theory of Abilities, developed in a systemic approach framework, is the theoretical basis of the research. The method of deploying a memorization activity, as elaborated by V.D. Shadrikov and L.V. Cheremoshkina, was the investigation tool used. The sample included students in grades 1 to 4 between ages 7 to 12 and included a total of 100 children (66 boys and 34 girls. The control group of primary school students with typical development included 105 children (50 boys and 55 girls. The research consisted of several stages: a pilot study, experimental research (the test task was to memorize card #1; the basic task was to memorize cards #2 and #3; to reproduce cards #2 and #3; and to poll the students, mathematical data processing, and a description of the levels of mnemonic ability development among primary students with developmental delays. The following procedures were employed during statistical analysis: Spearman r3, Mann-Whitney U-test, Jonckheere-Terpstra test, and Kruskal-Wallis test. The structure of mnemonic abilities in primary schoolchildren with developmental delays was determined to vary according to the underdevelopment of their operational mechanisms. For example, memory functions are based on the use of inborn mechanisms, and a portion of children differ in the

    Full Text Available Mathematics researchers generally agree that algebra is a tool for problem solving, a method of expressing relationship, analyzing and representing patterns, and exploring mathematical properties in a variety of problem situations. Thus, several mathematics researchers and educators have focused on investigating the introduction and the development of algebraic solving abilities. However research works on assessing students' algebraic solving ability is sparse in literature. The purpose of this study was to use the SOLO model as a theoretical framework for assessing Form Four students' algebraic solving abilities in using linear equation. The content domains incorporated in this framework were linear pattern (pictorial, direct variations, concepts of function and arithmetic sequence. This study was divided into two phases. In the first phase, students were given a pencil-and-paper test. The test comprised of eight superitems of four items each. Results were analyzed using a Partial Credit model. In the second phase, clinical interviews were conducted to seek the clarification of the students' algebraic solving processes. Results of the study indicated that 62% of the students have less than 50% probability of success at relational level. The majority of the students in this study could be classified into unistructural and multistructural. Generally, most of the students encountered difficulties in generalizing their arithmetic thinking through the use of algebraic symbols. The qualitative data analysis found that the high ability students seemed to be more able to seek the recurring linear pattern and identify the linear relationship between variables. They were able to co-ordinate all the information given in the question to form the algebraic expression and linear equations. Whereas, the low ability students showed an ability more on drawing and counting method. They lacked understanding of algebraic concepts to express the relationship

    Full Text Available A series of studies of cognitive abilities were conducted on a group of children at a context of poverty, in reason of learning about the quality of such capabilities, and in direct relationship to low school performance and subsequent risk of academic underachievement. Fifty three 4th year EGB-2 (Elementary School children of both sexes participated. They attend a suburban school outside the city of San Miguel de Tucumán, Argentina. Tests of Analogies and Building with Cubes of Wechsler ́s Intelligence Scale III (WISCIII were used in the process. Additionally, a register protocol was prepared by the research team. Outcomes were articulated with a demographic poll inquiring on the social-economic context of the children. Results reveal a proportion of 18.9 % of the children showing below standard records in cognitive abilities related to the aptitude in forming verbal concepts, and of 13.2 % in non- verbal concepts. Verbal abilities refer to the faculty of classifying and categorizing, for which the subject needs to organize, abstract and find relationship between facts or ideas and the comprehension of oral/audio assignments. Non- verbal abilities submit to the aptitude of making processes of analysis- synthesis and applying non- verbal reasoning to spatial relationships. This group of children was selected to receive – in second stage- training in these abilities through the Instrumental Enrichment Program.

    Listening is a life skill that is often developed during early childhood.it is one of the most important life skills that helps people become effective communicators for the rest of their lives.Listening ranks first among are the four basic skills that English learners in middle school should develop. The improvement of middle school students' listening ability is very helpful to the development of their abilities. However, the training of listening has not been placed in its proper position in traditional teaching for a long time and hence listening has long been a weak point. Many students think that listening is one of the most difficult things in English study. As the development of students' listening ability has become the demand of middle school's New English Curriculum Standard, nowadays the training of listening has drawn unprecedented attention than before. How to increase the students' ability in listening and how to improve students' listening comprehension in the examination has been the common concern of many English teachers'. this thesis tries to probe into middle school students' problems into listening and to seek solutions for these problems so as to improve their listening ability.

    Full Text Available The sample included 712 preschool boys and girls at the age of 4 to 7 years (mean 5.96 decimal years and standard deviation .96 from preschool institutions in Novi Sad, Sombor, Sremska Mitrovica and Bačka Palanka. Information concerning 36 indicators of aberrant behavior of the children were supplied by their parents, whereas their cognitive ability was tested by Raven’s progressive colored matrices. Based on factor analysis (promax method, four factors i.e. generators of aberrant behavior in children were singled out: aggression, anxiousness, dissociation, and hysteria, whose relations with cognitive functioning and age were also analyzed by factor analysis. Aberrant behavior and cognitive abilities show significant interrelatedness. Owing to orderly developed cognitive abilities, a child understands essence and reality of problems, realizes possibilities and manners of solving them, and succeeds in realizing successful psycho-social functioning. Developed cognitive abilities enable a child to recognize and understand her/his own reactions in different situations and develop manners of reacting, which leads to strengthening psycho-social safety and adapting behavior in accordance with her/his age and abilities.

The results showed that all the experimental fungi except Tricholama mongolicum had definite biodegradated abilities to the lignin and cellulose of straw. The Ideal fungus for straw degradation was screened out as Pleurotus ostreatus, which showed a higher degradation ability for lignin (17.86%) and lower degradation rate for cellulose (2.24%), with a Selection Factor (SF) of 7.97. The degradation rates of lignin and cellulose for other fungi ranged from 2.30% to 16.54% and 5.60% to 17.32%, respectively, and the SF was very low in range of 0.14 to 2.24.The ratio of colony's diameters to the color-zone (d1/d2) and SF are negative correlation, with a correlation coefficient of -0.1476.

  6. Uranium Dioxide Powder Flow ability Improvement Using Sol-Gel

    The improvement of flow ability characteristics of uranium dioxide powder has been done using sol-gel process. To anticipate a pellet mass production with uniform pellet dimension, the uranium dioxide powder must be have a spherical form. Uranium dioxide spherical powder has been diluted in acid transformed into sol colloidal solution. To obtain uranium dioxide spherical form, the uranium sol-colloidal solution has been dropped in a hot paraffin ( at the temperature of 900C) to form gelatinous colloid and then dried at 8000C, and sintered at the temperature of 17000C. The flow ability of spherical uranium dioxide powder has been examined by using Flowmeter Hall (ASTM. B. 213-46T). The measurement result reveals that the spherical uranium dioxide powder has a flow ability twice than that of unprocessed uranium dioxide powder

    Full Text Available Lactic acid bacteria strains isolated from traditional made cheeses constitute a reservoir of unexplored potential in biotechnology. In this study four autochthonous lactobacilli strains, isolated from traditional white brined cheeses and identified as Lactobacillus paracasei (08, 564, 05 and 02, were investigated on potential probiotic ability. The investigation comprised sensitivity to simulated gastrointestinal tract conditions, antimicrobial activity against wide range of pathogens, antibiotic resistance as well as autoaggregation ability. Lactobacillus rhamnosus GG was used as referent strain. Three tested strains grew well in simulated gastrointestinal conditions, but their sensitivity was greater on bile acids and pancreatin compared with pepsin low pH 2.5. The examined strains had different sensitivity to antibiotics, but three strains showed very good antimicrobial activity to pathogens. All strains demonstrated very good autoaggregation ability. For three of four examined strains of Lb. paracasei probiotic potential was similar with referent strain Lb. rhamnosus GG, determined in vitro

  12. Localization ability with bimodal hearing aids and bilateral cochlear implants

    Seeber, Bernhard U.; Baumann, Uwe; Fastl, Hugo

    2004-09-01

    After successful cochlear implantation in one ear, some patients continue to use a hearing aid at the contralateral ear. They report an improved reception of speech, especially in noise, as well as a better perception of music when the hearing aid and cochlear implant are used in this bimodal combination. Some individuals in this bimodal patient group also report the impression of an improved localization ability. Similar experiences are reported by the group of bilateral cochlear implantees. In this study, a survey of 11 bimodally and 4 bilaterally equipped cochlear implant users was carried out to assess localization ability. Individuals in the bimodal implant group were all provided with the same type of hearing aid in the opposite ear, and subjects in the bilateral implant group used cochlear implants of the same manufacturer on each ear. Subjects adjusted the spot of a computer-controlled laser-pointer to the perceived direction of sound incidence in the frontal horizontal plane by rotating a trackball. Two subjects of the bimodal group who had substantial residual hearing showed localization ability in the bimodal configuration, whereas using each single device only the subject with better residual hearing was able to discriminate the side of sound origin. Five other subjects with more pronounced hearing loss displayed an ability for side discrimination through the use of bimodal aids, while four of them were already able to discriminate the side with a single device. Of the bilateral cochlear implant group one subject showed localization accuracy close to that of normal hearing subjects. This subject was also able to discriminate the side of sound origin using the first implanted device alone. The other three bilaterally equipped subjects showed limited localization ability using both devices. Among them one subject demonstrated a side-discrimination ability using only the first implanted device.

    This paper studies career concerns in teams where the support a worker receives depends on fellow team members’ effort and ability. In this setting, by exerting effort and providing support, a worker can influence her own and her teammates’ performances in order to bias the learning process in her favor. To manipulate the market’s assessments, we argue that in equilibrium, a worker has incentives to help or even sabotage her colleagues in order to signal that she is of higher ability. In a mu...

    Full Text Available New parameter of geoecological protective ability of construction materials and articles is suggested. Effect is based on the fact that any solid surface possess centers of adsorption. It is shown that Broensted basic surface centers are active in adsorption of heavy metal ions from water solutions and materials having such centers on their surface are able to remove heavy metal ions from water and thus to protect soil from contamination with such ions. For example, foam concrete with ability to adsorb heavy metal ions may be used to protect soil near railway tracks.

  6. Salicaceae detoxification abilities in Florida tiger swallowtail butterflies (Papilio glaucus maynardi Gauthier): Novel ability or Pleistocene holdover?

    Matthew S.Lehnert; J.Mark Scriber

    2012-01-01

    Florida populations of the eastern tiger swallowtail butterfly,Papilio glaucus L.,have unique morphological features and ecological adaptations that have contributed to their subspecies status (P.g.maynardi Gauthier).We describe geographically unique abilities for detoxification of Carolina willow,Salix caroliniana Michx.(Salicaceae),for several Florida populations of P.g.maynardi.Of all the approximately 570 worldwide species of the Papilionidae,such Salicaceae detoxification abilities exist only in the allopatric North American western and northernmost species (P.rutulus Lucas,P.eurymedon Lucas and P.canadensis Rothschild & Jordan).Females of P.glaucus collected from populations in southeastern USA were examined for oviposition preference in 5-choice assays,and displayed a low preference for Salicaceae (<5%),but larvae from Florida populations exhibited a high survival (> 60%) on these plants.Detoxification abilities have previously shown to be autosomally inherited,and can be transferred via natural or hand-paired interspecific hybrid introgression.However,these Florida populations are at least 700-1 500 km from the nearest hybrids or the hybrid species,P.appalachiensis Pavulaan & Wright,which possess these detoxification abilities.In any case,the Z ( =X)-linked oviposition preferences for Salicaceae are lacking in these Florida populations,illustrating genetic independence of oviposition preference determination and larval survival/performance abilities.The orgins ofdetoxification abilities are unlikely to be due to recent climate-driven introgression,and may represent ancestral trait carry-overs from interglacial refugium populations of the Pleistocene epoch.

    Kowalczuck, Alexandre; Sydney, Gilson Blitzkow; Martinez, Elizabeth Ferreira; Cardoso, Rielson José Alves

    2016-01-01

    This in vitro study evaluated the cutting ability of reciprocating files and the deformations caused by their multiple use. Five Reciproc® R25 files were divided into five groups for 10 simulated root canal preparations each. The resin blocks were weighed and photographed (12.5X and 20X) before and after preparation. The canals were prepared according to the manufacturer's instructions. Enlargement of the root canals was evaluated by comparison of pre- and post-preparation images using a computer software. The preoperative and postoperative weight differences determined the cutting ability of repeatedly used instruments. The data were analyzed using Lilliefors and Friedman statistical tests. The cutting ability and enlargement of the canals gradually decreased after each use, with significant differences observed at the 8th and 9th repetitions, respectively. There was no evidence of file deformation. The cutting ability and enlargement of the simulated canals gradually decreased when a reciprocating file was used up to 10 times. PMID:26676196

  20. Does ability to walk reflect general functionality in inflammatory neuropathies?

    Draak, Thomas H P; Gorson, Kenneth C; Vanhoutte, Els K; van Nes, Sonja I; van Doorn, Pieter A; Cornblath, David R; van den Berg, Leonard H; Faber, Catharina G; Merkies, Ingemar S J

    2016-06-01

    The "ability to walk" is considered a benchmark for good clinical recovery and prognosis, particularly in patients with Guillain-Barré syndrome (GBS) and chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). However, it has never been determined whether being "able to walk" represents general functionality. The purpose of this study was to examine whether the ability to walk outside independently reflects general functional improvement in patients with GBS, CIDP, and gammopathy-related neuropathy (MGUSP). A total of 137 patients with newly diagnosed (or relapsing) GBS (55), CIDP (59), and MGUSP (23) were serially examined (1-year). Predefined arbitrary cut-offs (so-called patients' Functional-Acceptable-Clinical-Thresholds [FACTs]) were taken at the 50th, 75th, and 90th percentile of the Inflammatory-Rasch-built-Overall-Disability-Scale (I-RODS(©) ). We determined the proportion of patients able to walk outside independently that reached the postulated cut-offs. A mean total of 85%, 39%, and 12% of all patients able to walk reached 50th, 75th, and 90th percentile thresholds, respectively. These findings were not neuropathy type related. Our findings show that assessing only one construct of functionality (e.g., walking ability) does not reflect the full scope of daily/social functional deficits perceived by patients. The ability to walk shows a patient is doing better, but not necessarily doing well. The I-RODS(©) bypasses these limitations. PMID:26968437

    Yu Bangyong; Chen Zhanqing; Yu Linli

    2016-01-01

    Using the self-designed testing system, the seepage tests for cemented broken rocks were conducted, and the impact of different factors on water-resisting ability was analyzed. The results show that (1) seepage process of the cemented broken rocks can be divided into two categories:in one category, seepage insta-bility occurs after a period of time, in the other, the permeability decreases slowly and tends to be stable, and seepage instability does not occur;(2) cementing performance of cementing agent and grain size dis-tribution are the decisive factors for water-resisting ability, with the increase of cementing performance and the mass percentage of large grains, the water-resisting ability of the specimen strengthens; (3) aggregate type has little effect on seepage stability, for the specimens with different aggregate types, the permeability and the duration of seepage instability have small difference; (4) initial porosity has a certain effect on the water-resisting ability of the specimen, but has no decisive role. With the increase of the initial porosity, the duration of seepage instability decreases.

  11. Factors associated with work ability in the elderly: systematic review

    Juleimar Soares Coelho de Amorim

    2014-12-01

    Full Text Available OBJECTIVE: To synthesize the evidence on factors associated with the maintenance of work ability during the aging process. METHODS: SciELO, LILACS and PubMed databases were consulted, in order to find out studies in Portuguese, English and Spanish published from 2000 to 2013. Descriptors which encompassed terms related to work ability, aging and elderly were used. Quantitative observational studies were included to investigate the work ability and the effect of aging. Studies aiming at analyzing the clinical course of illnesses related to aging and/or papers and publications in the form of editorials, interviews, projects, clinical notes and preliminary or conceptual data were excluded. RESULTS: A total of 924 articles were obtained, but 27 were included in the analyses. Later on, 2 intervention and 8 repeated studies were excluded. Variables that showed negative correlations with work ability were the following: age, smoking, service time and physical demands in occupational activities. Satisfaction with life, sufficient income, physical activity, volunteerism and mental workload were considered positive associations that protect the elderly from functional loss. CONCLUSION: This study was reported as a protective mechanism against depression, disability and fragility, maintaining the well-being, good cognitive function and autonomy in daily activities. Increased investments in the health care of this population are needed regarding musculoskeletal and cardiorespiratory capacity. Physical activity must be encouraged by policies to foster health promotion.

  12. Looking ahead: anticipatory gaze and motor ability in infancy.

    Ettore Ambrosini

    Full Text Available The present study asks when infants are able to selectively anticipate the goals of observed actions, and how this ability relates to infants' own abilities to produce those specific actions. Using eye-tracking technology to measure on-line anticipation, 6-, 8- and 10-month-old infants and a control group of adults were tested while observing an adult reach with a whole hand grasp, a precision grasp or a closed fist towards one of two different sized objects. The same infants were also given a comparable action production task. All infants showed proactive gaze to the whole hand grasps, with increased degrees of proactivity in the older groups. Gaze proactivity to the precision grasps, however, was present from 8 months of age. Moreover, the infants' ability in performing precision grasping strongly predicted their ability in using the actor's hand shape cues to differentially anticipate the goal of the observed action, even when age was partialled out. The results are discussed in terms of the specificity of action anticipation, and the fine-grained relationship between action production and action perception.

  16. Genetic evaluation for cow fighting ability in the Valdostana breed

    M. Vevey

    2010-04-01

    Full Text Available This study aimed to exploit the genetic components of cow fighting ability in Valdostana breed. Data from 41 knockout competitions in three different weight categories (WC performed over two years were used. Two different variables to express fighting ability were considered: 1 a “placing score” (PS dependent on the position reached in each WC, and 2 a “relative placing score” (RPS, calculated as relative position within WC. A complete data set (COMP accounting for all fights (n=7157 or a reduced data set (REDU considering only the best annual PS or RPS for each cow (n=4563, were also compared through ANOVA, REML variance components’ estimates and EBVs’ correlation. The PS in the COMP showed the highest R2 (0.44, and h2 resulted 0.163. The PS in the REDU showed a lower R2 (0.25, similar h2 value (0.189, but higher repeatability than PS in the COMP (0.373 vs. 0.294. The RPS variable in both data sets gave similar genetic parameters, but the R2 models resulted very low (0.02-0.04. The use of the PS variable and the COMP seems the most promising system to evaluate cow fighting ability in Valdostana breed, and a substantial genetic component for this ability seems to exist.

  18. Impacts of Niche Breadth and Dispersal Ability on Macroevolutionary Patterns.

    Qiao, Huijie; Saupe, Erin E; Soberón, Jorge; Peterson, A Townsend; Myers, Corinne E

    2016-08-01

    We describe a spatially explicit simulation experiment designed to assess relative impacts of macroecological traits on patterns of biological diversification under changing environmental conditions. Using a simulation framework, we assessed impacts of species' niche breadth (i.e., the range of their abiotic tolerances) and dispersal ability on resulting patterns of speciation and extinction and evaluated how these traits, in conjunction with environmental change, shape biological diversification. Simulation results supported both niche breadth and dispersal ability as important drivers of diversification in the face of environmental change, and suggested that the rate of environmental change influences how species interact with the extrinsic environment to generate diversity. Niche breadth had greater effects on speciation and extinction than dispersal ability when climate changed rapidly, whereas dispersal ability effects were elevated when climate changed slowly. Our simulations provide a bottom-up perspective on the generation and maintenance of diversity under climate change, offering a better understanding of potential interactions between species' intrinsic macroecological characteristics and a dynamic extrinsic environment in the process of biological diversification.

  20. The work ability index and functional capacity among older workers

    Rosimeire S. Padula

    2013-08-01

    Full Text Available BACKGROUND: Decreases in functional ability due to aging can impair work capacity and productivity among older workers. OBJECTIVE: This study compares the sociodemographics, health conditions, and physical functioning abilities of young and old workers as well as correlates of physical functioning capacity with the work ability index (WAI. METHOD: This exploratory, cross-sectional study examined employees of a higher education institution (HEI and those of a metallurgical industry. Older workers (50 years old or above were matched for gender and occupation type with younger workers (less than 50 years old. The following evaluations were applied: the multidimensional assessment questionnaire (which included sociodemographic, clinical, health perception, and physical health indices, the WAI, and a battery of physical functional tests. RESULTS: Diseases and regularly used medications were more common among the group of aging workers. The WAI did not differ between groups (p=0.237. Both groups showed similar physical functional capacity performances with regard to walking speed, muscle strength, and lower limb physical functioning. Aging workers showed a poorer performance on a test of right-leg support (p=0.004. The WAI was moderately correlated with the sit-to-stand test among older female workers (r=0.573, p=0.051. CONCLUSIONS: Unfavorable general health conditions did not affect the assessment of work ability or most of the tests of physical functional capacity in the aging group.

  4. The factorial structure of cognitive abilities in childhood

    Ana Azevedo Martins

    2016-06-01

    Full Text Available Recent studies have shown contradictory evidence regarding cognitive abilities differentiation and organization in childhood. Cattell's investment theory postulated that during the early stages of life, the individual begins with a single and general ability (fluid intelligence, in which the relevance tends to decrease during adolescence, due to the appearance of differentiated abilities developed through the process of socialization and associated with the motivations, interests and experiences. This study analyses whether the factorial structure of the results in a battery of tests supports the existence of a general factor or, instead, a structure formed by different specific factors. A sample of 472 Portuguese children, aged between 4 and 10 years old, completed the Cognitive Competencies Scale for Children (ECCOs 4/10, and four subtests of the Wechsler Intelligence Scale for Children-Third Edition (WISC-III and Wechsler Preschool and Primary Scale of Intelligence – Revised (WPPSI-R. The adjustment of some models that reflect different psychometric theories of intelligence was tested by several confirmatory factor analyses (CFA. The implications of the tested models in the organization of cognitive abilities for cognitive development and school learning in childhood are also discussed.

  5. Development of musical abilities, measured by Bentley's test

    Barbara Smolej-Fritz

    2000-03-01

    Full Text Available The article presents a part of the research that deals with the development of musical abilities of children aged 7 to 14 years. The area of musical abilities being very complex, we focus onley on some view points; namely on those which are included in Bentley's test of musical abilities. The research includes 436 children from primary schools in Krško and Brežice and from the music schools in both towns. The results show that the achievements on Bentley's test increase by age with the children who are visiting music school as well as with those who are not; but with the first group the improvement is faster, and the development finishes earlier and on a higher level. In all the sub-tests and in the whole test, significant differences are shown in the benefit of the children who are visiting music school. On the whole, the differences between boys and girls are not significant, but some significant differences are being found within the two groups. The results of the research show some lawfulness in the development of basic music abilities and also some factors that influence it; so the results may be help at planning and modelling musical-pedagogic process.

  14. Instructional geographic information science Map overlay and spatial abilities

    Tricot, Thomas Alexander, II

    The fundamental goal of this study is to determine if the complex spatial concept of map overlay can be effectively learned by young adolescents through the utilization of an instructional technique based within the foundations of Instructional Geographic Information Science (InGIScience). Percent correct and reaction times were the measures used to analyze the ability of young adolescents to learn the intersect, erase, and union functions of map overlay. The ability to solve for missing inputs, output, or function was also analyzed. Young adolescents of the test group scored higher percent correct and recorded faster reaction times than those of the control group or adults of the expert group by the end of the experiment. The intersect function of map overlay was more difficult in terms of percent correct and reaction time than the erase or union functions. Solving for the first or second input consistently resulted in lower percent correct and higher reaction times throughout the experiment. No overall performance differences were shown to exist between males and females. Results of a subjective "real-world" test also indicated learning by young adolescents. This study has shown that the practice of repetitive instruction and testing has proven effective for enhancing spatial abilities with regard to the map overlay concept. This study found that with practice, young adolescents can learn the map overlay concept and perform at levels equal to or greater than adults. This study has helped to answer the question of whether this development of spatial abilities is possible.

  15. Neural underpinnings of superior action prediction abilities in soccer players.

    Makris, Stergios; Urgesi, Cosimo

    2015-03-01

    The ability to form anticipatory representations of ongoing actions is crucial for effective interactions in dynamic environments. In sports, elite athletes exhibit greater ability than novices in predicting other players' actions, mainly based on reading their body kinematics. This superior perceptual ability has been associated with a modulation of visual and motor areas by visual and motor expertise. Here, we investigated the causative role of visual and motor action representations in experts' ability to predict the outcome of soccer actions. We asked expert soccer players (outfield players and goalkeepers) and novices to predict the direction of the ball after perceiving the initial phases of penalty kicks that contained or not incongruent body kinematics. During the task, we applied repetitive transcranial magnetic stimulation (rTMS) over the superior temporal sulcus (STS) and the dorsal premotor cortex (PMd). Results showed that STS-rTMS disrupted performance in both experts and novices, especially in those with greater visual expertise (i.e. goalkeepers). Conversely, PMd-rTMS impaired performance only in expert players (i.e. outfield players and goalkeepers), who exhibit strong motor expertise into facing domain-specific actions in soccer games. These results provide causative evidence of the complimentary functional role of visual and motor action representations in experts' action prediction. PMID:24771282

    Full Text Available The current body of research often focuses on the problem of cognitive decline through ageing. People adapt to these changes of cognitive resources by using brain reserve. An overview of results of different studies on how cognitive abilities of older adults decline highlights high variability of conclusions and sometimes contradiction but it has been shown older adults can be as good as or even better than younger participants in specific domains. Among others, personal meaningfulness of a situation and closeness to the researcher can be strong factors when assessing cognitive abilities and the aim of this paper was to research how these effect cognitive efficiency. In the pilot study we eliminated the factor of laboratory setting and checked how cognitive efficiency and abilities change in relation to motivation. Forty-eight participants, divided into two age groups, were asked to pass a proverb interpretation test. The results showed that participant’s subjective view on the researcher, perceived closeness, correlated with the adequacy in proverb interpretation. Both groups scored higher on adequacy of interpretation when they perceived to be close to the researcher. The younger adults outperformed the older but those in the older adults’ group, who felt to be close to the researcher scored as well as younger adults who didn’t perceived to be close to the researcher. This motivational reserve might play a role in assessing cognitive abilities and pathologies that affect the outcome of neuropsychological tests.

    Alexandre KOWALCZUCK

    2016-01-01

    Full Text Available Abstract This in vitro study evaluated the cutting ability of reciprocating files and the deformations caused by their multiple use. Five Reciproc® R25 files were divided into five groups for 10 simulated root canal preparations each. The resin blocks were weighed and photographed (12.5X and 20X before and after preparation. The canals were prepared according to the manufacturer’s instructions. Enlargement of the root canals was evaluated by comparison of pre- and post-preparation images using a computer software. The preoperative and postoperative weight differences determined the cutting ability of repeatedly used instruments. The data were analyzed using Lilliefors and Friedman statistical tests. The cutting ability and enlargement of the canals gradually decreased after each use, with significant differences observed at the 8th and 9th repetitions, respectively. There was no evidence of file deformation. The cutting ability and enlargement of the simulated canals gradually decreased when a reciprocating file was used up to 10 times.

  12. An effective method for incoherent scattering radar's detecting ability evaluation

    Lu, Ziqing; Yao, Ming; Deng, Xiaohua

    2016-06-01

    Ionospheric incoherent scatter radar (ISR), which is used to detect ionospheric electrons and ions, generally, has megawatt class transmission power and hundred meter level antenna aperture. The crucial purpose of this detecting technology is to get ionospheric parameters by acquiring the autocorrelation function and power spectrum of the target ionospheric plasma echoes. Whereas the ISR's echoes are very weak because of the small radar cross section of its target, estimating detecting ability will be significantly instructive and meaningful for ISR system design. In this paper, we evaluate the detecting ability through signal-to-noise ratio (SNR). The soft-target radar equation is deduced to be applicable to ISR, through which we use data from International Reference Ionosphere model to simulate signal-to-noise ratio (SNR) of echoes, and then comparing the measured SNR from European Incoherent Scatter Scientific Association and Advanced Modular Incoherent Scatter Radar with the simulation. The simulation results show good consistency with the measured SNR. For ISR, the topic of this paper is the first comparison between the calculated SNR and radar measurements; the detecting ability can be improved through increasing SNR. The effective method for ISR's detecting ability evaluation provides basis for design of radar system.

  15. The Use of "Literary Fiction" to Promote Mentalizing Ability.

    Pino, Maria Chiara; Mazza, Monica

    2016-01-01

    Empathy is a multidimensional process that incorporates both mentalizing and emotional sharing dimensions. Empathic competencies are important for creating interpersonal relationships with other people and developing adequate social behaviour. The lack of these social components also leads to isolation and exclusion in healthy populations. However, few studies have investigated how to improve these social skills. In a recent study, Kidd and Castano (2013) found that reading literary fiction increases mentalizing ability and may change how people think about other people's emotions and mental states. The aim of our study was to evaluate the effects of reading literary fiction, compared to nonfiction and science fiction, on empathic abilities. Compared to previous studies, we used a larger variety of empathy measures and utilized a pre and post-test design. In all, 214 healthy participants were randomly assigned to read a book representative of one of three literary genres (literary fiction, nonfiction, science fiction). Participants were assessed before and after the reading phase using mentalizing and emotional sharing tests, according to Zaki and Ochsner' s (2012) model. Comparisons of sociodemographic, mentalizing, and emotional sharing variables across conditions were conducted using ANOVA. Our results showed that after the reading phase, the literary fiction group showed improvement in mentalizing abilities, but there was no discernible effect on emotional sharing abilities. Our study showed that the reading processes can promote mentalizing abilities. These results may set important goals for future low-cost rehabilitation protocols for several disorders in which the mentalizing deficit is considered central to the disease, such as Autism Spectrum Disorders and Schizophrenia.

  17. Fine Motor Skills Predict Maths Ability Better than They Predict Reading Ability in the Early Primary School Years

    Pitchford, Nicola J.; Papini, Chiara; Outhwaite, Laura A.; Gulliford, Anthea

    2016-01-01

    Fine motor skills have long been recognized as an important foundation for development in other domains. However, more precise insights into the role of fine motor skills, and their relationships to other skills in mediating early educational achievements, are needed to support the development of optimal educational interventions. We explored concurrent relationships between two components of fine motor skills, Fine Motor Precision and Fine Motor Integration, and early reading and maths development in two studies with primary school children of low-to-mid socio-economic status in the UK. Two key findings were revealed. First, despite being in the first 2 years of primary school education, significantly better performance was found in reading compared to maths across both studies. This may reflect the protective effects of recent national-level interventions to promote early literacy skills in young children in the UK that have not been similarly promoted for maths. Second, fine motor skills were a better predictor of early maths ability than they were of early reading ability. Hierarchical multiple regression revealed that fine motor skills did not significantly predict reading ability when verbal short-term memory was taken into account. In contrast, Fine Motor Integration remained a significant predictor of maths ability, even after the influence of non-verbal IQ had been accounted for. These results suggest that fine motor skills should have a pivotal role in educational interventions designed to support the development of early mathematical skills. PMID:27303342

  1. SOME THOUGHTS ON DEVELOPING THE STUDENTS'LISTENING ABILITY

    徐惠文

    2002-01-01

    @@ Language is the means by which people communicate with each other. At present, the teaching of listening is considered one of the most important teaching courses. Listening greatly affects communicative ability. For this reason, it is necessary for students to break through obstacles to the listening to improve their abilities. In recent years, theories have been put forward in the teaching of listening. The focus of attention has shifted from the teachers, who have tended to be the center of the class to the students. Listening and spoken English are the key features of English classes. As English teachers, we should devote ourselves to the reforms of teaching systems and develop suitable teaching methods so that we could improve the quality of listening teaching.

  3. Identifying high ability students: a contribution from neuropsychological indicators

    Dora Cortat Simonetti

    2010-06-01

    Full Text Available This paper presents some data on the convergence between psychometric intelligence measurements (IQ tests and physiological signs of mental activity found in high ability adolescents. The research study focus on a small group of 15 subjects submitted to electric encephalograms, previously chosen from a larger group of 77 classmates on the basis of scores on the WISC-III IQ Test. The results suggest continuous predominance of Alpha waves for the gifted group (higher frequency percentile and higher amplitude what was not observed in the group without any superior intellectual ability. Even taking into account methodological limitations, this study may contribute to the understanding of a relationship between the intellectual quotient (IQ and alpha waves frequency and amplitude, as observed during performance on cognitive tasks. Such results may suggest a possibility to complement psychometric measures with encephalic registers in giftedness research studies.

  4. The evaluation of the radiation shielding ability of lead glass

    Positron emission tomography (PET) scanning with the tracer 2-[F-18] Fluoro-2deoxy-D-glucose (FDG) is widely used in the clinical PET. However, the photon energy used in the PET scans is considerably higher than that of the X-rays traditionally used in the diagnoses. The radiation protection in the PET institution, therefore, is the remaining problem. Meanwhile, lead glass has attracted considerable attention as a radiation-shielding material for the PET institution. The aim of the present study was to evaluate the radiation-shielding ability of the lead glass against the positron emitters. The shielding ability evaluations were done both in the actual experiments and in the Monte Carlo simulation. The lead glass, the object of evaluation in this study, proved to have sufficient protective effect. The development and the spread of a thinner and lighter lead glass with the same effective dose transmission factor should be expected in the near future. (author)

    Baker, Rachel K; Pettigrew, Tamara L; Poulin-Dubois, Diane

    2014-02-01

    The goal of the present research was to examine whether infants associate different paths of motion with animate beings and inanimate objects. An infant-controlled habituation procedure was used to examine 10-20-month-old infants' ability to associate a non-linear motion path (jumping) with animals and a linear (rebounding) motion path with vehicles (Experiment 1) and furniture (Experiment 2). During the habituation phase, infants saw a dog jumping over a barrier and either a vehicle or a piece of furniture rebounding off the barrier. In the test phase, infants looked longer when another inanimate object jumped rather than rebounded, but showed no such differential looking in the case of another animate object. The ability to restrict the animate motion path of jumping to animate beings was present by 10 months of age. The present findings support the hypothesis that motion path is associated with the animate-inanimate distinction early in infancy. PMID:24486789

    2010-01-01

    Abstract Background Set-shifting is impaired in people with anorexia nervosa (AN), but the underlying physiological and biochemical processes are unclear. Animal studies have established that glutamatergic pathways in the prefrontal cortex play an important role in set-shifting ability. However, it is not yet understood whether levels of serum glutamatergic amino acids are associated with set-shifting performance in humans. The aim of this study was to determine whether serum concentrations o...

  19. Polyelectrolytes Ability in Reducing Atrazine Concentration in Water: Surface Effects

    2014-01-01

    This paper reports on the direct ability of two positively charged organic polyelectrolytes (natural-based and synthetic) to reduce the atrazine concentration in water. The adsorption study was set up using multiple glass vessels with different polymer dosing levels followed by ultrafiltration with a 1 kDa membrane. The addition of polymers exhibited a capability in reducing the atrazine concentration up to a maximum of 60% in surface-to-volume ratio experiments. In the beginning, the theoret...

    2010-01-01

    Remotely sensed tracking technology has revealed remarkable migration patterns that were previously unknown; however, models to optimally use such data have developed more slowly. Here, we present a hierarchical Bayes state-space framework that allows us to combine tracking data from a collection of animals and make inferences at both individual and broader levels. We formulate models that allow the navigation ability of animals to be estimated and demonstrate how information can be combined ...

  1. White matter microstructural properties correlate with sensorimotor synchronization abilities.

    Blecher, Tal; Tal, Idan; Ben-Shachar, Michal

    2016-09-01

    Sensorimotor synchronization (SMS) to an external auditory rhythm is a developed ability in humans, particularly evident in dancing and singing. This ability is typically measured in the lab via a simple task of finger tapping to an auditory beat. While simplistic, there is some evidence that poor performance on this task could be related to impaired phonological and reading abilities in children. Auditory-motor synchronization is hypothesized to rely on a tight coupling between auditory and motor neural systems, but the specific pathways that mediate this coupling have not been identified yet. In this study, we test this hypothesis and examine the contribution of fronto-temporal and callosal connections to specific measures of rhythmic synchronization. Twenty participants went through SMS and diffusion magnetic resonance imaging (dMRI) measurements. We quantified the mean asynchrony between an auditory beat and participants' finger taps, as well as the time to resynchronize (TTR) with an altered meter, and examined the correlations between these behavioral measures and diffusivity in a small set of predefined pathways. We found significant correlations between asynchrony and fractional anisotropy (FA) in the left (but not right) arcuate fasciculus and in the temporal segment of the corpus callosum. On the other hand, TTR correlated with FA in the precentral segment of the callosum. To our knowledge, this is the first demonstration that relates these particular white matter tracts with performance on an auditory-motor rhythmic synchronization task. We propose that left fronto-temporal and temporal-callosal fibers are involved in prediction and constant comparison between auditory inputs and motor commands, while inter-hemispheric connections between the motor/premotor cortices contribute to successful resynchronization of motor responses with a new external rhythm, perhaps via inhibition of tapping to the previous rhythm. Our results indicate that auditory

  2. THE RELATIONSHIP BETWEEN ENCODING ABILITY AND AGGRESSIVE BEHAVIOR.

    Tsamis, Vasiliki J; Rebok, George W; Montague, David R

    2009-03-26

    While past research efforts have reported a relationship between encoding ability and aggressive behavior in children, the relationship between encoding ability and adult aggressiveness has not been examined. Encoding, an element of attention, refers to the ability to recall and reorder information stored in memory. Using selected cognitive tests and a self-report measure of aggressive behavior in a sample of community college students (n=55), this study investigated the relationship between encoding ability and aggressive behavior, (i.e., physical aggression, verbal aggression, anger, hostility, indirect aggression, and total aggression). Aggressive behavior was assessed by the Aggression Questionnaire of the Buss-Durkee Hostility Inventory, a widely-used measure of aggressive behavior. Encoding was measured using the WAIS-III Digit Span and Arithmetic subtests. Initial analyses showed no significant correlations between the cognitive measures and the five scales of aggressive behavior. However, there was a significant age-related association between scores on the cognitive measures and the indices of aggressive behavior. Two groups were created, those who reported attention problems and those who did not report attention problems. When the two groups were compared, participants who had a history of attention problems were verbally more aggressive than participants with a negative history of attention problems, and they were generally more aggressive. A composite score, called an "encoding score," was related to scores on the aggressive behavior scales. Moreover, the age-related relationship between these two variables suggests that the relationship is maturational and may disappear as an individual ages. Concerning the latter, participants in the current study were enrolled in junior college. Therefore, persons who had attention problems and were aggressive may not have pursued higher education.

    2013-01-01

    Different kinds of experience during early life can play a significant role in the development of an animal's behavioural phenotype. In natural contexts, this influences behaviours from anti-predator responses to navigation abilities. By contrast, for animals reared in captive environments, the homogeneous nature of their experience tends to reduce behavioural flexibility. Studies with cage-reared rodents indicate that captivity often compromises neural development and neural plasticity. Such...

  9. Home Care Technology Through an Ability Expectation Lens

    2014-01-01

    Home care is on the rise, and its delivery is increasingly reliant on an expanding variety of health technologies ranging from computers to telephone “health apps” to social robots. These technologies are most often predicated on expectations that people in their homes (1) can actively interact with these technologies and (2) are willing to submit to the action of the technology in their home. Our purpose is to use an “ability expectations” lens to bring together, and provide some synthesis of, the types of utility and disadvantages that can arise for people with disabilities in relation to home care technology development and use. We searched the academic databases Scopus, Web of Science, EBSCO ALL, IEEE Xplore, and Compendex to collect articles that had the term “home care technology” in the abstract or as a topic (in the case of Web of Science). We also used our background knowledge and related academic literature pertaining to self-diagnosis, health monitoring, companionship, health information gathering, and care. We examined background articles and articles collected through our home care technology search in terms of ability expectations assumed in the presentation of home care technologies, or discussed in relation to home care technologies. While advances in health care support are made possible through emerging technologies, we urge critical examination of such technologies in terms of implications for the rights and dignity of people with diverse abilities. Specifically, we see potential for technologies to result in new forms of exclusion and powerlessness. Ableism influences choices made by funders, policy makers, and the public in the development and use of home health technologies and impacts how people with disabilities are served and how useful health support technologies will be for them. We urge continued critical examination of technology development and use according to ability expectations, and we recommend increasing incorporation

    2015-01-01

    Many studies have examined attention mechanisms involved in specific behavioral tasks (e.g., search, tracking, distractor inhibition). However, relatively little is known about the relationships among those attention mechanisms. Is there a fundamental attention faculty that makes a person superior or inferior at most types of attention tasks, or do relatively independent processes mediate different attention skills? We focused on individual differences in voluntary visual-attention abilities ...

    2012-01-01

    The temporoparietal junction (TPJ) is a key node within the "social brain". Several studies suggest that the TPJ controls representations of the self or another individual across a variety of low-level (agency discrimination, visual perspective taking, control of imitation) and high-level (mentalizing, empathy) sociocognitive processes. We explored whether sociocognitive abilities relying on on-line control of self and other representations could be modulated with transcranial direct current ...

  1. Absolute Pitch: Effects of Timbre on Note-Naming Ability

    Patrícia Vanzella; E Glenn Schellenberg

    2010-01-01

    BACKGROUND: Absolute pitch (AP) is the ability to identify or produce isolated musical tones. It is evident primarily among individuals who started music lessons in early childhood. Because AP requires memory for specific pitches as well as learned associations with verbal labels (i.e., note names), it represents a unique opportunity to study interactions in memory between linguistic and nonlinguistic information. One untested hypothesis is that the pitch of voices may be difficult for AP pos...

For assessment of jumping and throwing athletic disciplines four tests were used: long jump, high jump, shot put and javelin. Data analysis was performed with canonical correlation and regression analysis. The results showed a statistically significant correlation between functional abilities with all of tests in jumping and throwing athletic disciplines.

  14. Predictive Technologies: Can Smart Tools Augment the Brain's Predictive Abilities?

    Pezzulo, Giovanni; D'Ausilio, Alessandro; Gaggioli, Andrea

    2016-01-01

    The ability of "looking into the future"-namely, the capacity of anticipating future states of the environment or of the body-represents a fundamental function of human (and animal) brains. A goalkeeper who tries to guess the ball's direction; a chess player who attempts to anticipate the opponent's next move; or a man-in-love who tries to calculate what are the chances of her saying yes-in all these cases, people are simulating possible future states of the world, in order to maximize the success of their decisions or actions. Research in neuroscience is showing that our ability to predict the behavior of physical or social phenomena is largely dependent on the brain's ability to integrate current and past information to generate (probabilistic) simulations of the future. But could predictive processing be augmented using advanced technologies? In this contribution, we discuss how computational technologies may be used to support, facilitate or enhance the prediction of future events, by considering exemplificative scenarios across different domains, from simpler sensorimotor decisions to more complex cognitive tasks. We also examine the key scientific and technical challenges that must be faced to turn this vision into reality. PMID:27199648

  15. Predicting Spanish–English Bilingual Children’s Language Abilities

    Hammer, Carol Scheffner; Komaroff, Eugene; Rodriguez, Barbara L.; Lopez, Lisa M.; Scarpino, Shelley E.; Goldstein, Brian

    2012-01-01

    Purpose In this study, the authors investigated factors that affect bilingual children’s vocabulary and story recall abilities in their 2 languages. Method Participants included 191 Latino families and their children, who averaged 59 months of age. Data on parental characteristics and children’s exposure to and usage of Spanish and English were collected. The authors assessed children’s Spanish and English vocabulary and story recall abilities using subtests of the Woodcock–Muñoz Language Survey—Revised (Woodcock, Muñoz-Sandoval, Ruef, & Alvarado, 2005). Results Sizeable percentages of variation in children’s English (R2 = .61) and Spanish (R2 = .55) vocabulary scores were explained by children’s exposure to, and usage of, each language and maternal characteristics. Similarly, variations in children’s story recall scores in English (R2 = .38) and Spanish (R2 = .19) were also explained by the factors considered in this investigation. However, the authors found that different sets of factors in each category affected children’s vocabulary and story recall abilities in each language. Conclusions Children’s exposure to and usage of their two languages as well as maternal characteristics play significant roles in bilingual individuals’ language development. The results highlight the importance of gathering detailed sociolinguistic information about bilingual children when these children are involved in research and when they enter the educational system.

    Diana ARAPOVIKJ

    2008-06-01

    Full Text Available This research was carried out on a young girl with Williams syndrome, whose syntactical ability was tested longitudinally over a period of 22 months, from age 9 years and 3 months to 11 years and 1 month. The assumption was that the girl with Wil­liams syndrome would have poorer syntactical ability than children with regular development, but similar to children with specific language impair­ment (SLI and that in all tasks she would achieve better results in the final testing. Syntax was ana­lyzed on the basis of the fundamental variable of repeating sentences, which consisted of five sub-variables: literal repetition of sentences, sentences repeated with omissions, ungrammatical repetition of sentences, sentences with altered content, sen­tences not repeated. A statistical difference was found between the syntactical ability of the girl with Williams’ syndrome and children with normal development in all tested sub-variables, and her results were the same as in children with specific language impairment. Moreover, in the final test­ing the girl achieved better results than in the ini­tial test.

Results in cooperative learning group were further analyzed according to students' gender, abilities and cognitive style. No significant interaction between students' achievement and their gender or abilities were found. Statistically significant interactions between students' cognitive style and achievement were found in both courses. Field-dependent students benefited most from cooperative learning.

  18. Training communication abilities in Rett Syndrome through reading and writing

    ILARIACASTELLI

    2013-12-01

    Full Text Available The goal of this clinical case study is to investigate the possibility of training communication abilities in people with Rett syndrome (RS. Usually, girls with RS never exceed the sensorimotor stage of development, but the inter-individual variability typical of RS may lead us to doubt the irrevocability of that developmental limit, especially for those girls who are engaged in cognitive rehabilitation. The case study reported here concerns a 21 year old girl with RS who was engaged in cognitive rehabilitation training based upon the principles of Feuerstein’s modificability and mediated learning theory. The training aimed to teach her basic concepts and enhance reading-writing abilities. Statistical analyses showed that the girl reached adequate reading-writing abilities, proving the validity of the cognitive intervention which allowed her to communicate by composing words with her forefinger on an alphabetic table. Although these results need to be cautiously considered as they derive from a single case study, they have implications for future cognitive rehabilitation for deeply impaired clinical conditions as in the case of RS.

    Full Text Available Six parents of Jatropha curcas were crossed in half diallel fashion, and the F1s were evaluated to determine the combining ability for nine germination parameters. The ratio between general combining ability (GCA and specific combining ability (SCA variances indicated preponderance of additive gene action for all the characters except germination percentage, time of 50% germination, seedling length, and seedling vigor index. The parents P1 and P2 were the best general combiner for most of the characters studied. The cross P1×P5 was the best specific combiner for speed of emergence, germination percentage, germination energy, germination index, and seedling vigor index, the cross P2×P5 for mean germination time, time of 50% germination, and seedling length, and the cross P4×P5 for number of days to first germination. The germination percentage varied from 58.06 to 92.76% among the parents and 53.43 to 98.96% among the hybrids. The highest germination (98.96% was observed in hybrid P2×P4, and none of the hybrids or parents showed 100% germination. The highest germination index (GI and seedling vigor index (SVI were found in hybrid P1×P5 and P2×P5, respectively. The results of this study provide clue for the improvement of Jatropha variety through breeding program.

    Recent structural and functional neuroimaging studies of adults suggest that efficient patterns of brain connectivity are fundamental to human intelligence. Specifically, whole brain networks with an efficient small-world organization, along with specific brain regions (i.e., Parieto-Frontal Integration Theory, P-FIT) appear related to intellectual ability. However, these relationships have not been studied in children using structural network measures. This cross-sectional study examined the relation between non-verbal intellectual ability and structural network organization in 99 typically developing healthy preadolescent children. We showed a strong positive association between the network's global efficiency and intelligence, in which a subtest for visuo-spatial motor processing (Block Design, BD) was prominent in both global brain structure and local regions included within P-FIT as well as temporal regions involved with pattern and form processing. BD was also associated with rich club organization, which encompassed frontal, occipital, temporal, hippocampal, and neostriatal regions. This suggests that children's visual construction ability is significantly related to how efficiently children's brains are globally and locally integrated. Our findings indicate that visual construction and reasoning may make general demands on globally integrated processing by the brain. PMID:26385010

    This study examines major comorbidities in children with severe cerebral palsy and the feasibility of psychological tests for measuring abilities in a more impaired population. Eighty psychological evaluations of children with cerebral palsy aged 1.8 to 15.4 years (mean = 5.6) were analyzed. Major comorbid disorders were correlated with severity of motor disability. More than half of the cohort were diagnosed with severe cerebral palsy according to the Gross Motor Function Classification System. Multiple subtests were combined in order to assess the intellectual level. Normal intelligence was found in 22.5%, and 41.3% had moderate or severe intellectual impairment. Epilepsy occurred in 32.5% and attention-deficit hyperactivity disorder (ADHD) in 22.5%. Intellectual disability correlated with motor ability and with epilepsy. In a logistic regression model, epilepsy and motor ability score predicted 29.9% of IQ score variance. Intellectual impairment and epilepsy are common comorbidities. Subtests from different scales should be applied and interpreted with caution. PMID:25855688

    Physical activity in schools is declining in many countries and inactivity in childhood has become a recognized risk factor. Data from a program of professionally guided physical exercise in primary school children were collected before and after the academic year of training. Four thousand five hundred children (6-10 years) were enrolled, and conditional and coordinative motor abilities (speed, trunk flexibility, long jumping, somersault, Harre circuit test) were measured. Anthropometric measurements were focused on body mass index (BMI), weight and height. Females never showed a significant variation of BMI, whereas males in the first and fourth grades showed significant differences. On the contrary, when considering the motor abilities studied, all the comparisons were highly significant. At the end of training, both males and females did better than at the beginning, and males were constantly faster than females. Our data, generated on a large number of children, show that professionally guided programs of physical education in the primary school lead to significant progresses in the development of conditional and coordinative abilities, without altering BMI values, thus not interfering with the balanced progression of body weight and height.

    Full Text Available  The purpose of this study was to investigate the influence of gender and educational level on scientific creativity among gifted/talented students. A cohort of creatividad científica y alta habilidad: diferencias de género y nivel educativo 78 secondary school students from 12 to 16 years old participated in this research. The scientific creativity was measured using the Creative Scientific Ability Test (Sak & Ayas, 2011 designed for secondary school students from 11 to 14 years old. Its theoretical framework sets up the measurement of a three dimensional structure: general creative abilities (fluency, flexibility and creativity, scientific creative abilities (hypothesis generation, hypothesis testing and evidence evaluation and scientific knowledge. This test has the right adequate psychometric properties with a Cronbach’s alpha coefficient of 0.848 (Sak & Ayas, 2013. Results indicated that male students scored significantly higher in a task named Interaction Graph which measures hypothesis generation in interdisciplinary science. The analysis also showed that students involved in upper education levels scores significantly higher in general fluency and in the task called The Food Chain which measures evidence evaluation in the area of ecology.

    Most perceived parameters of sound (e.g. pitch, duration, timbre) can also be imagined in the absence of sound. These parameters are imagined more veridically by expert musicians than non-experts. Evidence for whether loudness is imagined, however, is conflicting. In music, the question of whether loudness is imagined is particularly relevant due to its role as a principal parameter of performance expression. This study addressed the hypothesis that the veridicality of imagined loudness improves with increasing musical expertise. Experts, novices and non-musicians imagined short passages of well-known classical music under two counterbalanced conditions: 1) while adjusting a slider to indicate imagined loudness of the music and 2) while tapping out the rhythm to indicate imagined timing. Subtests assessed music listening abilities and working memory span to determine whether these factors, also hypothesised to improve with increasing musical expertise, could account for imagery task performance. Similarity between each participant's imagined and listening loudness profiles and reference recording intensity profiles was assessed using time series analysis and dynamic time warping. The results suggest a widespread ability to imagine the loudness of familiar music. The veridicality of imagined loudness tended to be greatest for the expert musicians, supporting the predicted relationship between musical expertise and musical imagery ability. PMID:23460791

    Full Text Available The research determined influence of motor abilities on alpine ski learning. Moreover, the aim was also to estimate the contribution of some morphological characteristics to acquisition of ski knowledge. At the beginning of the study, participants were tested by tests evaluating balance, agility, explosive and static strength, movement frequency and flexibility. After evaluation of motor abilities, basic morphological characteristics were noted and then participants entered a seven days alpine ski course. Acquired alpine ski knowledge was assessed through demonstration of seven elements of alpine ski technique, by five independent judges. Data analysis showed positive influence of agility on all tested elements of alpine ski technique (traversing, β = .38; β = .26; uphill turn, β = .33; β = .23; basic turn, β = .18; parallel turn, β = .32; short turn, β = .34. Subjects’ results in squat endurance test assessing the static leg strength contribute to learning uphill turn (β = .19, basic turn (β = .35 and parallel turn (β = .27. Test used to measure balance (single leg balance test significantly influences learning of basic elements of alpine ski technique (traversing right, β = .23; traversing left, β = .28; uphill turn to the left, β = .24. Body height has a negative effect on alpine ski learning (β = -0.5, indicating that taller ski beginners tend to have more difficulties during alpine ski learning than shorter alpine ski beginners. According to our results, agility, static leg strength and balance are the motor abilities with the greatest influence on beginners’ alpine ski learning

  7. Influence of Intravenous Injection of Hydroxyapatite on Mouse Movement Ability

    2014-01-01

    Lactic acid is usually formed during strenuous exercise, and a large amount of lactic acid and slow anaerobic glycolysis in muscle lead to limitations of movement ability. Hydroxyapatite (HAp) is an alkaline inorganic material with a good biocompatibility. It slowly degrades in vivo and releases trace amounts of calcium ions, reducing cell damage by reacting with polylactic acid and neutralizing local acid environment. Whether HAp can reduce the concentration of lactic acid in vivo and improve movement ability is not yet clear. Here, after eight days of training, 40 mice were randomly divided into four groups: control, distilled water, sodium bicarbonate and HAp group. After one day of rest, the mice were intravenously injected via the lateral tail veins with 1 ml distilled water, sodium bicarbonate and HAp suspension (2.2 mg/ml), respectively, and subjected to a swimming exhaustive experiment (load 10%). The swimming time of mice in the water, under water and total time were recorded. The exhaustive exercise mice were immediately subject to abdominal cavity anaesthesia. The concentrations of blood, gastrocnemius and myocardial lactic acid as well as serum LDH activity were detected. We demonstrate that HAp can significantly prolong swimming time and improve serum LDH activity, but does not affect lactic acid concentration. In conclusion, intravenous injection of HAp nanoparticles can significantly improve the exhaustive swimming ability of mice mainly because of the elevated blood LDH activity induced by HAp.

  8. Manganese inhibits the ability of astrocytes to promote neuronal differentiation

    Manganese (Mn) is a known neurotoxicant and developmental neurotoxicant. As Mn has been shown to accumulate in astrocytes, we sought to investigate whether Mn would alter astrocyte-neuronal interactions, specifically the ability of astrocytes to promote differentiation of neurons. We found that exposure of rat cortical astrocytes to Mn (50-500 μM) impaired their ability to promote axonal and neurite outgrowth in hippocampal neurons. This effect of Mn appeared to be mediated by oxidative stress, as it was reversed by antioxidants (melatonin and PBN) and by increasing glutathione levels, while it was potentiated by glutathione depletion in astrocytes. As the extracellular matrix protein fibronectin plays an important role in astrocyte-mediated neuronal neurite outgrowth, we also investigated the effect of Mn on fibronectin. Mn caused a concentration-dependent decrease of fibronectin protein and mRNA in astrocytes lysate and of fibronectin protein in astrocyte medium; these effects were also antagonized by antioxidants. Exposure of astrocytes to two oxidants, H2O2 and DMNQ, similarly impaired their neuritogenic action, and led to a decreased expression of fibronectin. Mn had no inhibitory effect on neurite outgrowth when applied directly onto hippocampal neurons, where it actually caused a small increase in neuritogenesis. These results indicate that Mn, by targeting astrocytes, affects their ability to promote neuronal differentiation by a mechanism which is likely to involve oxidative stress.

  12. Multidimensional assessment of empathic abilities: neural correlates and gender differences.

    Empathy is a multidimensional construct and comprises the ability to perceive, understand and feel the emotional states of others. Gender differences have been reported for various aspects of emotional and cognitive behaviors including theory of mind. However, although empathy is not a single ability but a complex behavioral competency including different components, most studies relied on single aspects of empathy, such as perspective taking or emotion perception. To extend those findings we developed three paradigms to assess all three core components of empathy (emotion recognition, perspective taking and affective responsiveness) and clarify to which extent gender affects the neural correlates of empathic abilities. A functional MRI study was performed with 12 females (6 during their follicular phase, 6 during their luteal phase) and 12 males, measuring these tasks as well as self-report empathy questionnaires. Data analyses revealed no significant gender differences in behavioral performance, but females rated themselves as more empathic than males in the self-report questionnaires. Analyses of functional data revealed distinct neural networks in females and males, and females showed stronger neural activation across all three empathy tasks in emotion-related areas, including the amygdala. Exploratory analysis of possible hormonal effects indicated stronger amygdala activation in females during their follicular phase supporting previous data suggesting higher social sensitivity and thus facilitated socio-emotional behavior. Hence, our data support the assumption that females and males rely on divergent processing strategies when solving emotional tasks: while females seem to recruit more emotion and self-related regions, males activate more cortical, rather cognitive-related areas.

    Early language and reading abilities have been shown to correlate with a variety of musical skills and elements of music perception in children. It has also been shown that reading impaired children can show difficulties with music perception. However, it is still unclear to what extent different aspects of music perception are associated with language and reading abilities. Here we investigated the relationship between cognitive-linguistic abilities and a music discrimination task that preserves an ecologically valid musical experience. 43 Portuguese-speaking students from an elementary school in Brazil participated in this study. Children completed a comprehensive cognitive-linguistic battery of assessments. The music task was presented live in the music classroom, and children were asked to code sequences of four sounds on the guitar. Results show a strong relationship between performance on the music task and a number of linguistic variables. A principle component analysis of the cognitive-linguistic battery revealed that the strongest component (Prin1) accounted for 33% of the variance and Prin1 was significantly related to the music task. Highest loadings on Prin1 were found for reading measures such as Reading Speed and Reading Accuracy. Interestingly, 22 children recorded responses for more than four sounds within a trial on the music task, which was classified as Superfluous Responses (SR). SR was negatively correlated with a variety of linguistic variables and showed a negative correlation with Prin1. When analyzing children with and without SR separately, only children with SR showed a significant correlation between Prin1 and the music task. Our results provide implications for the use of an ecologically valid music-based screening tool for the early identification of reading disabilities in a classroom setting. PMID:23785339

    The desulfurization ability of refining slag with relative lower basicity (B) and Al2O3 content (B=3.5−5.0;20wt%−25wt%Al2O3) was studied. Firstly, the component activities and sulfide capacity (CS) of the slag were calculated. Then slag−metal equilibrium experiments were carried out to measure the equilibrium sulfur distribution (LS). Based on the laboratorial experiments, slag composition was optimized for a better desulfurization ability, which was verified by industrial trials in a steel plant. The obtained results indicated that an MgO-saturated CaO−Al2O3−SiO2−MgO system with the basicity of about 3.5−5.0 and the Al2O3 content in the range of 20wt%−25wt%has high activity of CaO (aCaO), with no deterioration of CS compared with conventional desulfurization slag. The measured LS between high-strength low-alloyed (HSLA) steel and slag with a basicity of about 3.5 and an Al2O3 content of about 20wt%and between HSLA steel and slag with a basicity of about 5.0 and an Al2O3 content of about 25wt%is 350 and 275, respectively. The new slag with a basicity of about 3.5−5.0 and an Al2O3 content of about 20wt%has strong desulfurization ability. In particular, the key for high-efficiency desulfurization is to keep oxygen potential in the reaction system as low as possible, which was also verified by industrial trials.

  16. Absolute pitch: effects of timbre on note-naming ability.

    Patrícia Vanzella

    Full Text Available BACKGROUND: Absolute pitch (AP is the ability to identify or produce isolated musical tones. It is evident primarily among individuals who started music lessons in early childhood. Because AP requires memory for specific pitches as well as learned associations with verbal labels (i.e., note names, it represents a unique opportunity to study interactions in memory between linguistic and nonlinguistic information. One untested hypothesis is that the pitch of voices may be difficult for AP possessors to identify. A musician's first instrument may also affect performance and extend the sensitive period for acquiring accurate AP. METHODS/PRINCIPAL FINDINGS: A large sample of AP possessors was recruited on-line. Participants were required to identity test tones presented in four different timbres: piano, pure tone, natural (sung voice, and synthesized voice. Note-naming accuracy was better for non-vocal (piano and pure tones than for vocal (natural and synthesized voices test tones. This difference could not be attributed solely to vibrato (pitch variation, which was more pronounced in the natural voice than in the synthesized voice. Although starting music lessons by age 7 was associated with enhanced note-naming accuracy, equivalent abilities were evident among listeners who started music lessons on piano at a later age. CONCLUSIONS/SIGNIFICANCE: Because the human voice is inextricably linked to language and meaning, it may be processed automatically by voice-specific mechanisms that interfere with note naming among AP possessors. Lessons on piano or other fixed-pitch instruments appear to enhance AP abilities and to extend the sensitive period for exposure to music in order to develop accurate AP.

Firstly, the component activities and sulfide capacity ( C S) of the slag were calculated. Then slag-metal equilibrium experiments were carried out to measure the equilibrium sulfur distribution ( L S). Based on the laboratorial experiments, slag composition was optimized for a better desulfurization ability, which was verified by industrial trials in a steel plant. The obtained results indicated that an MgO-saturated CaO-Al2O3-SiO2-MgO system with the basicity of about 3.5-5.0 and the Al2O3 content in the range of 20wt%-25wt% has high activity of CaO ( a CaO), with no deterioration of C S compared with conventional desulfurization slag. The measured L S between high-strength low-alloyed (HSLA) steel and slag with a basicity of about 3.5 and an Al2O3 content of about 20wt% and between HSLA steel and slag with a basicity of about 5.0 and an Al2O3 content of about 25wt% is 350 and 275, respectively.

  18. Characterizing AOGCM Ability to Simulate Northern Hemisphere Teleconnection Patterns

    Hertel-Stoner, A.; Hayhoe, K.; Tebaldi, C.; Wuebbles, D.

    2007-12-01

    An important aspect of coupled atmosphere-ocean general circulation models (AOGCM) is their ability to simulate variability in regional and global atmospheric dynamics. This is particularly true for recurring teleconnection patterns known to be correlated with surface climate anomalies. Here, we evaluate the ability of all IPCC AR4 historical 20C3M AOGCM simulations for which the required output fields are available to simulate five present- day patterns of large-scale atmospheric internal variability in the Northern Hemisphere: the Arctic Oscillation (AO), the North Atlantic Oscillation (NAO), the Pacific/North American Oscillation (PNA), the Pacific Decadal Oscillation (PDO), and the El Niño - Southern Oscillation (ENSO). We evaluate these patterns in two ways: first, in terms of their characteristic temporal variability, and second, in terms of their magnitude and spatial locations. We find that historical total forcing simulations from nearly all of the AOGCMs are able to produce seasonal spatial patterns that clearly resemble the teleconnection patterns that result when identical calculation methods are applied to ECMWF ERA-40 and NCEP / NCAR reanalysis fields. However, many AOGCMs tend to either over- or underestimate the strength of the patterns, and also tend to rotate the AO, NAO, PNA, and PDO about the polar region. Furthermore, based on spectral analysis of the time series of each index, AOGCMs also vary in their ability to simulate the temporal variability of the teleconnection patterns, with some models oscillating too fast and others too slow relative to observed. We conclude, therefore, that although historical simulations from all the AOGCMs examined here were able to produce patterns that resemble those seen in reanalysis fields, significant biases still remain in model representation of these patterns, including biases in the strength and/or location of the patterns as well as in their temporal variability.

    Purpose. The aim of the study was to compare the spatial component of proprioceptive ability by reproducing a upper limb movement typical in table tennis and fencing. Methods. The research comprised 41 young males of which 12 were table tennis players, 14 fencers, and 15 not involved in any competitive sports as a control. The experiment was based on assessing the precision of pronation and supination of the forearm at the elbow joint in recreating a set movement range by use of a goniometer....

  2. Commentary: The Development of Creativity-Ability, Motivation, and Potential.

    Silvia, Paul J; Christensen, Alexander P; Cotter, Katherine N

    2016-03-01

    A major question for research on the development of creativity is whether it is interested in creative potential (a prospective approach that uses measures early in life to predict adult creativity) or in children's creativity for its own sake. We suggest that a focus on potential for future creativity diminishes the fascinating creative world of childhood. The contributions to this issue can be organized in light of an ability × motivation framework, which offers a fruitful way for thinking about the many factors that foster and impede creativity. The contributions reflect a renewed interest in the development of creativity and highlight how this area can illuminate broader problems in creativity studies. PMID:26994729

  3. Mental ability and common sense in an artificial society

    Malarz, Krzysztof

    2014-01-01

    We read newspapers and watch TV every day. There are many issues and many controversies. Since media are free, we can hear arguments from every possible side. How do we decide what is wrong or right? The first condition to accept a message is to understand it; messages that are too sophisticated are ignored. So it seems reasonable to assume that our understanding depends on our ability and our current knowledge. Here we show that the consequences of this statement are surprising and funny.

    Notenboom, Kim; Vromans, Herman; Schipper, Maarten; Leufkens, Hubert G. M.; Bouvy, Marcel L.

    2016-01-01

    Background: Practical problems with the use of medicines, such as difficulties with breaking tablets, are an often overlooked cause for non-adherence. Tablets frequently break in uneven parts and loss of product can occur due to crumbling and powdering. Health characteristics, such as the presence of peripheral neuropathy, decreased grip strength and manual dexterity, can affect a patient's ability to break tablets. As these impairments are associated with aging and age-related diseases, such as Parkinson's disease and arthritis, difficulties with breaking tablets could be more prevalent among older adults. The objective of this study was to investigate the relationship between age and the ability to break scored tablets. Methods: A comparative study design was chosen. Thirty-six older adults and 36 young adults were systematically observed with breaking scored tablets. Twelve different tablets were included. All participants were asked to break each tablet by three techniques: in between the fingers with the use of nails, in between the fingers without the use of nails and pushing the tablet downward with one finger on a solid surface. It was established whether a tablet was broken or not, and if broken, whether the tablet was broken accurately or not. Results: The older adults experienced more difficulties to break tablets compared to the young adults. On average, the older persons broke 38.1% of the tablets, of which 71.0% was broken accurately. The young adults broke 78.2% of the tablets, of which 77.4% was broken accurately. Further analysis by mixed effects logistic regression revealed that age was associated with the ability to break tablets, but not with the accuracy of breaking. Conclusions: Breaking scored tablets by hand is less successful in an elderly population compared to a group of young adults. Health care providers should be aware that tablet breaking is not appropriate for all patients and for all drugs. In case tablet breaking is unavoidable, a

  7. The multisensory brain and its ability to learn music.

    Zimmerman, Emily; Lahav, Amir

    2012-04-01

    Playing a musical instrument requires a complex skill set that depends on the brain's ability to quickly integrate information from multiple senses. It has been well documented that intensive musical training alters brain structure and function within and across multisensory brain regions, supporting the experience-dependent plasticity model. Here, we argue that this experience-dependent plasticity occurs because of the multisensory nature of the brain and may be an important contributing factor to musical learning. This review highlights key multisensory regions within the brain and discusses their role in the context of music learning and rehabilitation. PMID:22524357

  8. Uranium prospecting and geological favour ability in Uruguay

    Uranium prospecting carried out in Uruguay since 1976 is described. On the basis of literature available and of an analysis of the large structural units pertinent to Uruguay's geology, the prospecting performed in general in the northeast of the country, and in particular in the districts of Cerro Largo and Las Canas, is described. Some information is presented on uranium favour ability in Uruguay related to sedimentary formations: Devonian (Cerrezuelo Formation) and Gondwana (San Gregorio and Tres Islas Formations), and to the Crystalline formations of the centre and Southwest (1700-2000 m.y.) and of the east and southeast (500-700 m.y.)

  9. The Competent Client and the Complexity of Dis-ability

    Randi Rolvsjord

    2014-11-01

    Full Text Available Clients and therapists in the interdisciplinary discourse of mental health and mental health care are described as dichotomous. In such a binary the client is defined in terms of weakness, pathology and passivity, while the therapist is described in terms of strengths, expertise and activity. This article aims to contribute to the destabilization of the client-therapist binary by offering a review of literature on competent clients. Perspectives from social models and cultural models in disability studies provide the theoretical frames for the discussion. Social constraints and oppression with regard to the dis-ability complex and discursive implications are discussed.

    2010-01-01

    We investigate the composition dependence of glass-forming ability (GFA) of a series of iron-containing soda lime borate liquids by substituting Na2O for B2O3. We have characterized GFA by measuring the glass stability against crystallization using a differential scanning calorimeter (DSC). The results show that the GFA decreases when substituting Na2O for B2O3. Moreover, we find that there is no direct link between the kinetic fragility and GFA for the soda lime borate series studied herein....

  11. Normalizing renal reducing ability prevents adriamycin-induced proteinuria

    Reactive oxygen species play an important role in adriamycin (ADR) nephropathy. We showed by in vivo electron paramagnetic resonance (EPR) that renal reducing ability (RRA) declined on the 7th day after ADR administration. Proteinuria appeared after the decline in RRA. The aim of this study was to prove by in vivo EPR whether the decline in RRA is altered by scavengers such as dimethyl sulfoxide (DMSO) and dimethylthiourea (DMTU) and that it is this change which is responsible for the proteinuria in ADR nephropathy. By showing that DMSO and DMTU ameliorate the RRA, we demonstrate that the decline in RRA is related to ADR-induced proteinuria

  12. Increasing of Switching Abilities of High Voltage Circuit Breakers

    RUSTEMLI, Sabir

    2015-01-01

    The most effective way of increasing switching abilities of high voltage circuit breakers in energy transmission systems is to influence around zero degree to short circuit currents (Maljkovic Z et al 2000; Gashimov, A.M et al. 2001;Antipov, K.M et al. 1985; Gashimov A.M 1991). For this reason, transformers neutral points should be grounded variously for limitation of asymmetric short circuit currents. But another way for this limitation is grounded of transformers neutral points over non-lin...

  13. Evaluating the ability of goalkeepers in English Premier League football

    Gelade Garry

    2014-01-01

    This paper examines the performance of goalkeepers in the English Premier League. A commonly used metric to assess goalkeeper ability is the saves-to-shots ratio. It is shown that goalkeepers playing in weak teams have to defend against on-target shots that have a relatively high probability of scoring as compared to their counterparts in higher-performing teams. This tends to produce a downwards bias in the save-to-shots ratio of goalkeepers in weak teams, an effect which may lead to their a...

  14. Irradiation effects on the alcohol fermentation ability of saccharomyces cerevisiae

    Irradiation effects on the alcohol fermentation ability of saccharomyces cerevisiae. S. cerevisiae suspensions of 1.5x108 clls/ml were exposed to single and fractionated doses of gamma irradiation, i.e. 0; 0.30; 0.60; 0.90; and 1.20 kGy in aerobic condition at dose rate of 1.63 kGy/hour. The fractionated doses were given with time interval of 15, 30 and 45 minutes. The fermentation was held at 300C for 40 hours. It is seen that an increase of alcohol production was obtained when cells were irradiated at 0.60 kGy, although the result has no significant difference statistically with control. At the dose of 1.20 kGy the alcohol fermentation ability of S. cerevisiae decreased drastically as compared to control. Irradiation using single or fractionated doses with time interval of 15-45 minutes did not influence the alcohol production. Comparing the time interval of 45 minutes at 0.60 kGy and at 1.20 kGy, it appeared that the yield of alcohol was different. (author). 17 refs.; 4 figs

  16. Recent loss of vitamin C biosynthesis ability in bats.

    Jie Cui

    Full Text Available The traditional assumption that bats cannot synthesize vitamin C (Vc has been challenged recently. We have previously shown that two Old World bat species (Rousettus leschenaultii and Hipposideros armiger have functional L-gulonolactone oxidase (GULO, an enzyme that catalyzes the last step of Vc biosynthesis de novo. Given the uncertainties surrounding when and how bats lost GULO function, exploration of gene evolutionary patterns is needed. We therefore sequenced GULO genes from 16 bat species in 5 families, aiming to establish their evolutionary histories. In five cases we identified pseudogenes for the first time, including two cases in the genus Pteropus (P. pumilus and P. conspicillatus and three in family Hipposideridae (Coelops frithi, Hipposideros speoris, and H. bicolor. Evolutionary analysis shows that the Pteropus clade has the highest ω ratio and has been subjected to relaxed selection for less than 3 million years. Purifying selection acting on the pseudogenized GULO genes of roundleaf bats (family Hipposideridae suggests they have lost the ability to synthesize Vc recently. Limited mutations in the reconstructed GULO sequence of the ancestor of all bats contrasts with the many mutations in the ancestral sequence of recently emerged Pteropus bats. We identified at least five mutational steps that were then related to clade origination times. Together, our results suggest that bats lost the ability to biosynthesize vitamin C recently by exhibiting stepwise mutation patterns during GULO evolution that can ultimately lead to pseudogenization.

  17. Ability grouping and science education reform: Policy and research base

    Lynch, Sharon

    This article reviews current policy trends concerning the practice of ability grouping in K-12 science education. Relevant statements of key policy-making, policy-influencing organizations such as the NSTA, AAAS, NSF, the National Research Council, the U.S. Office of Education Department of Civil Rights, NAACP, the National Governors' Association, programs related to the Jacob Javits Grants for the Gifted and Talented, and others are summarized. The author's interpretation of the various positions are presented herein. The article also explores the research base supporting the various policies on grouping by examining selected general research literature on grouping, followed by research that is science education specific. Methodological issues color the research findings. The ethical and pragmatic implications of developing research and policy are discussed. The conclusions are that there is a dearth of recent empirical research specifically related to ability grouping in science, and that the time is ripe for the concerted development of a research agenda by key players in science education reform. Moreover, as controversial and value-laden as the topic is, it should be noted that grouping practices alone are unlikely to influence science education reform unless considered in the context of comprehensive restructuring efforts at the local school level.Received: 10 April 1993; Revised: 26 August 1993;

  18. Profiling oral narrative ability in young school-aged children.

    Westerveld, Marleen F; Gillon, Gail T

    2010-06-01

    This study aimed to determine if oral narrative comprehension and production measures derived in a fictional story retelling task could be used to create a profile of strengths and weaknesses in oral narrative ability (Profile of Oral Narrative Ability: PONA) in young school-aged children. The story retelling task was field-tested with 169 typically developing children, aged between 5;0 and 7;6 years. Children listened twice to an unfamiliar story while looking at the pictures in a book. Comprehension questions were asked after the first exposure. Following the second exposure, children were asked to retell the story without the use of the pictures. Story retellings were analysed on measures of semantics, morphosyntax, verbal productivity, and narrative quality. Results indicated sensitivity for age on measures of comprehension, narrative quality, semantics, and verbal productivity, but not for morphosyntactic measures. Factor analysis indicated that oral narrative performance comprised three factors, explaining more than 80% of the variance. Two clinical case examples are presented, which show the potential of the PONA to reveal different patterns of strengths and weaknesses across the oral narrative measures. Although early evidence suggests the potential usefulness of the PONA, further research is now needed to test the validity, reliability and clinical application of this tool. PMID:20433337

  19. Genetic analysis of milking ability in Lacaune dairy ewes

    2006-02-01

    Full Text Available Abstract The milking ability of Lacaune ewes was characterised by derived traits of milk flow patterns, in an INRA experimental farm, from a divergent selection experiment in order to estimate the correlated effects of selection for protein and fat yields. The analysis of selected divergent line effects (involving 34 616 data and 1204 ewes indicated an indirect improvement of milking traits (+17% for maximum milk flow and -10% for latency time with a 25% increase in milk yield. Genetic parameters were estimated by multi-trait analysis with an animal model, on 751 primiparous ewes. The heritabilities of the traits expressed on an annual basis were high, especially for maximum flow (0.54 and for latency time (0.55. The heritabilities were intermediate for average flow (0.30, time at maximum flow (0.42 and phase of increasing flow (0.43, and low for the phase of decreasing flow (0.16 and the plateau of high flow (0.07. When considering test-day data, the heritabilities of maximum flow and latency time remained intermediate and stable throughout the lactation. Genetic correlations between milk yield and milking traits were all favourable, but latency time was less milk yield dependent (-0.22 than maximum flow (+0.46. It is concluded that the current dairy ewe selection based on milk solid yield is not antagonistic to milking ability.

    Due to the rapid rise of aged populations throughout the world, it is essential to elucidate the cause of taste dysfunction, because it may reduce appetite, leading to inadequate dietary intake. We aimed to compare taste detection ability between dependently and independently living geriatric individuals of nearly the same age with oral status. Forty-three elderly individuals considered to be cognitively eligible and residing in nursing homes in Japan were enrolled (n = 43, 82·3 ± 8·5 years) and were compared with an independently living elderly group (n = 949, 79·9 ± 0·8 years), aiming to compare taste detection ability between dependently and independently living elders of nearly the same age. Information regarding comorbidity and medication was obtained as general health status, and oral status including number of present teeth, denture usage and maximal occlusal force was also noted. In the dependently living group, 69·4%, 14·3%, 16·3% and 8·2% of participants could detect sweet, sour, salty and bitter tastes, respectively, which was significantly lower than the independently living group for each taste (97·9%, 70·8%, 89·6% and 43·8% for sweet, sour, salty and bitter tastes, respectively). The multivariate logistic regression analysis revealed that residing in nursing homes was associated with reduced sensitivity for four different tastes. The diseases and the situation of dependent elders were more likely the cause of the decreased taste sensitivity. PMID:27027615

    Rhythm organizes events in time and plays a major role in music, but also in the phonology and prosody of a language. Interestingly, children with developmental dyslexia-a learning disability that affects reading acquisition despite normal intelligence and adequate education-have a poor rhythmic perception. It has been suggested that an accurate perception of rhythmical/metrical structure, that requires accurate perception of rise time, may be critical for phonological development and subsequent literacy. This hypothesis is mostly based on results showing a high degree of correlation between phonological awareness and metrical skills, using a very specific metrical task. We present new findings from the analysis of a sample of 48 children with a diagnosis of dyslexia, without comorbidities. These children were assessed with neuropsychological tests, as well as specifically-devised psychoacoustic and musical tasks mostly testing temporal abilities. Associations were tested by multivariate analyses including data mining strategies, correlations and most importantly logistic regressions to understand to what extent the different auditory and musical skills can be a robust predictor of reading and phonological skills. Results show a strong link between several temporal skills and phonological and reading abilities. These findings are discussed in the framework of the neuroscience literature comparing music and language processing, with a particular interest in the links between rhythm processing in music and language.

    Full Text Available The aim of the study was to evaluate the ability of motor learning based on objective, metric criteria, in terms of pedagogical process aimed at improving the accuracy of hits a golf ball to the target. A group of 77 students of physical education participated in the study. Within 8 months there were performed 11 measurement sessions. In each session, subjects performed 10 hits a golf ball to the target from a distance of 9 m. Accuracy of hits was recorded. Effect of motor learning has been demonstrated in the progress of 10 consecutive hits a golf ball to the target in each session (operational control; in the dynamics of performance improvement between sessions (current control; as well as in the total result of eight-month experiment (stage control. There were developed norms for quantitative and qualitative assessment of accuracy of hits a golf ball to the target. Developed quantitative and qualitative criteria for assessing the speed of motor learning in various conditions of the educational process creates the possibility of organization the operational, current and stage control of the level of human coordination motor abilities, as required by leading process.

    2014-09-01

    Full Text Available Given the growing importance of the saladette fresh tomato market in Brazil, the objective of this paper was to assess the combining abilities of lines potentially useful as parents of hybridsin this class. The experiment consisted of28 genotypes, 18 hybrids from a partial diallel crossobtained from crossing two groups of tomato lines (Group I, with 9 parents, and Group II, with 2 parents, 8 F1 experimental hybrids, and 2 commercial checks. Traits evaluated were total yield, mean fruit mass, fruit shelf life, shape and percentsoluble solids. Additive genetic effects were generally more important than non-additive effects for all traits evaluated. The TOM-542 and TOM-734 lines, from group I, and the TOM-720 line, from group II, presented high general combining ability (GCA estimates for most of the traits of importance for saladette tomatoes, and were therefore considered suitable parents of hybrids of this class. Higher fruit shelf life of TOM-723 as a parental line compared with TOM-720 (Group II, was mainly attributed to the presence in the former of the norA allele, which controls longer fruit shelf life. F1 hybrids (TOM-542 x TOM-720, (TOM-580 x TOM-720, (TOM-734 x TOM-720, and (TOM-727 x TOM-720 showed good performance and fruit quality and thus constitute possible commercial varieties.

  5. Development of gaze following abilities in wolves (Canis lupus.

    Friederike Range

    Full Text Available The ability to coordinate with others' head and eye orientation to look in the same direction is considered a key step towards an understanding of others mental states like attention and intention. Here, we investigated the ontogeny and habituation patterns of gaze following into distant space and behind barriers in nine hand-raised wolves. We found that these wolves could use conspecific as well as human gaze cues even in the barrier task, which is thought to be more cognitively advanced than gazing into distant space. Moreover, while gaze following into distant space was already present at the age of 14 weeks and subjects did not habituate to repeated cues, gazing around a barrier developed considerably later and animals quickly habituated, supporting the hypothesis that different cognitive mechanisms may underlie the two gaze following modalities. More importantly, this study demonstrated that following another individuals' gaze around a barrier is not restricted to primates and corvids but is also present in canines, with remarkable between-group similarities in the ontogeny of this behaviour. This sheds new light on the evolutionary origins of and selective pressures on gaze following abilities as well as on the sensitivity of domestic dogs towards human communicative cues.

  6. Gender, Culture, and Sex-Typed Cognitive Abilities

    Reilly, David

    2012-01-01

    Although gender differences in cognitive abilities are frequently reported, the magnitude of these differences and whether they hold practical significance in the educational outcomes of boys and girls is highly debated. Furthermore, when gender gaps in reading, mathematics and science literacy are reported they are often attributed to innate, biological differences rather than social and cultural factors. Cross-cultural evidence may contribute to this debate, and this study reports national gender differences in reading, mathematics and science literacy from 65 nations participating in the 2009 round of the Programme for International Student Assessment (PISA). Consistently across all nations, girls outperform boys in reading literacy, d = −.44. Boys outperform girls in mathematics in the USA, d = .22 and across OECD nations, d = .13. For science literacy, while the USA showed the largest gender difference across all OECD nations, d = .14, gender differences across OECD nations were non-significant, and a small female advantage was found for non-OECD nations, d = −.09. Across all three domains, these differences were more pronounced at both tails of the distribution for low- and high-achievers. Considerable cross-cultural variability was also observed, and national gender differences were correlated with gender equity measures, economic prosperity, and Hofstede’s cultural dimension of power distance. Educational and societal implications of such gender gaps are addressed, as well as the mechanisms by which gender differences in cognitive abilities are culturally mediated. PMID:22808072

    Full Text Available Two-year investigations (1998-1999 of diallel crosses with four parent cultivars of burley tobacco (TN 86, Saturn, Bs 92, Bols 100 and their six F1 hybrids were carried out at the experimental field of Tobacco Institute Zagreb in Pitomača. The trial was set up according to the RCBD in four replications. Standard agrotehnics for this tobacco type were applied in tobacco growing. The goal of these investigation was to estimate on specific genetic materials the values of parent genotypes as combiners and the best specific cross combinations for agronomic (yield, price and income and morphological traits (topping height, leaf number, days to flowering, leaf length, leaf width and leaf area and internode length. Significant differences between parents and F1 hybrids were found for all investigation traits and years according to analysis of variance. Significant general and specific combining ability were also estimated for all investigation traits, except of specific combining ability for price in both investigation years. According to the GCA/SCA ratio, a higher GCA values were estimated for most traits. The cultivars TN 86 and Bs 92 were the best general combiners, while TN 86 x Bs 92, TN 86 x Bols 100 i Bs 92 x Bols 100 were the best specific combinations in both investigation years.

  8. Cell Matrix Remodeling Ability Shown by Image Spatial Correlation

    Chi-Li Chiu

    2013-01-01

    Full Text Available Extracellular matrix (ECM remodeling is a critical step of many biological and pathological processes. However, most of the studies to date lack a quantitative method to measure ECM remodeling at a scale comparable to cell size. Here, we applied image spatial correlation to collagen second harmonic generation (SHG images to quantitatively evaluate the degree of collagen remodeling by cells. We propose a simple statistical method based on spatial correlation functions to determine the size of high collagen density area around cells. We applied our method to measure collagen remodeling by two breast cancer cell lines (MDA-MB-231 and MCF-7, which display different degrees of invasiveness, and a fibroblast cell line (NIH/3T3. We found distinct collagen compaction levels of these three cell lines by applying the spatial correlation method, indicating different collagen remodeling ability. Furthermore, we quantitatively measured the effect of Latrunculin B and Marimastat on MDA-MB-231 cell line collagen remodeling ability and showed that significant collagen compaction level decreases with these treatments.

  9. Climbing Ability of the Common Bed Bug (Hemiptera: Cimicidae).

    Hottel, B A; Pereira, R M; Gezan, S A; Qing, R; Sigmund, W M; Koehler, P G

    2015-05-01

    Little is known about what factors influence the climbing ability of bed bugs, Cimex lectularius L. (Hemiptera: Cimicidae), in relation to the various surfaces they encounter. We examined how sex, time since last fed, and what surfaces the bed bugs were in contact with affected their climbing performance. The effects of sex and time since fed were tested by counting the number of bed bugs able to climb a 45° slope. The pulling force was recorded using an analytical balance technique that captured the sequential vertical pulling force output of bed bugs attached to various surfaces. Recently fed female bed bugs were found to have the most difficulty in climbing smooth surfaces in comparison with males. This difference can be explained by the larger weight gained from bloodmeals by female bed bugs. A variety of vertical pulling forces were observed on surfaces ranging from sandpaper to talc powder-covered glass. For surfaces not treated with talc powder, bed bugs generated the least amount of vertical pulling force from synthetically created 0.6-µm plastron surfaces. This vast range in the ability of bed bugs to grip onto various surfaces may have implications on limiting bed bugs dispersal and hitchhiking behaviors. PMID:26334801

  10. Relationship between football playing ability and selected performance measures.

    2002-11-01

    The relationships between football playing ability (FPA) and selected anthropometric and performance measures were determined among NCAA Division I-A football players (N = 40). Football playing ability (determined by the average of coaches' rankings) was significantly correlated with vertical jump (VJ) in all groups (offense, defense, and position groups of wide receiver-defensive back, offensive linemen-defensive linemen, and running back-tight end-linebacker). Eleven of 50 correlations (groups by variables), or 22%, were important for FPA. Five of the 11 relationships were related to VJ. Forward stepwise regression equations for each group explained over half of the criterion variable, FPA, as indicated by the R(2) values for each model. Vertical jump was the prime predictor variable in the equations for all groups. The findings of this study are discussed in relation to the specificity hypothesis. Strength and conditioning programs that facilitate the capacity for football players to develop forceful and rapid concentric action through plantar flexion of the ankle, as well as extension of the knee and hip, may be highly profitable.

  11. Numbers and letters: exploring an autistic savant's unpracticed ability.

    Pring, Linda; Hermelin, Beate

    2002-01-01

    This paper describes an individual with autism and high-level calendar calculation ability who could perform a set of unpracticed letter/number association tasks. The savant's performance was compared with that of two control participants, one a departmental secretary and the other a professor of mathematics. The facility with which the savant could master the rules governing the relationships between the series of items suggests that he possessed a flexibility of mental processing transcending his ability of calendar calculation. Furthermore, he could recalibrate previous knowledge to solve new hitherto unpracticed tasks. When presented with novel problems, the savant, unlike the mathematician, made no initial errors at all on any of the presented tasks, thereby indicating his fast and spontaneous recognition of new rules and of new relationships between items. It is concluded that a cognitive style of 'weak central coherence' as adopted by autistic savants may protect single representations from being retained in the form of stable enduring wholes, and that such a segmentation strategy may allow for the transformation, reorganization and reconstruction of the relationship between single items of information.

  12. Hunger state affects both olfactory abilities and gustatory sensitivity.

    Hanci, Deniz; Altun, Huseyin

    2016-07-01

    Chemical senses such as odor, taste and appearance are directly related with appetite. Understanding the relation between appetite and flavor is getting more important due to increasing number of obese patients worldwide. The literature on the studies investigating the change in olfactory abilities and gustatory sensitivity mostly performed using food-related odors and tastes rather than standardized tests were developed to study olfaction and gustation. Therefore, results are inconsistent and the relationship between olfactory and gustatory sensitivity with respect to the actual state of human satiety is still not completely understood. Here, for the first time in literature, we investigated the change in both olfactory abilities and gustatory sensitivity in hunger and in satiety using 123 subjects (37 men, 86 women; mean age 31.4 years, age range 21-41 years). The standardized Sniffin' Sticks Extended Test and Taste Strips were used for olfactory testing and gustatory sensitivity, respectively. TDI score (range 1-48) was calculated as the collective scores of odor threshold (T), odor discrimination (D) and odor identification (I). The evaluation was performed in two successive days where the hunger state of test subjects was confirmed by blood glucose test strips (mean blood glucose level 90.0 ± 5.6 mg/dl in hunger and 131.4 ± 8.1 mg/dl in satiety). The results indicated statistically significant decrease in olfaction in satiety compared to hunger (mean TDI 39.3 ± 1.1 in hunger, 37.4 ± 1.1 in satiety, p < 0.001). The comparison of gustatory sensitivity indicated significantly higher sensitivity to sweet, sour and salty in hunger (p < 0.001), but significantly higher sensitivity to bitter tastant in satiety (p < 0.001). With this prospective study, we were able to show that both olfactory abilities and gustatory sensitivity were affected by hunger state. PMID:25744049

  13. A New Measure of Imagination Ability: Anatomical Brain Imaging Correlates

    Jung, Rex E.; Flores, Ranee A.; Hunter, Dan

    2016-01-01

    Imagination involves episodic memory retrieval, visualization, mental simulation, spatial navigation, and future thinking, making it a complex cognitive construct. Prior studies of imagination have attempted to study various elements of imagination (e.g., visualization), but none have attempted to capture the entirety of imagination ability in a single instrument. Here we describe the Hunter Imagination Questionnaire (HIQ), an instrument designed to assess imagination over an extended period of time, in a naturalistic manner. We hypothesized that the HIQ would be related to measures of creative achievement and to a network of brain regions previously identified to be important to imagination/creative abilities. Eighty subjects were administered the HIQ in an online format; all subjects were administered a broad battery of tests including measures of intelligence, personality, and aptitude, as well as structural Magnetic Resonance Imaging (sMRI). Responses of the HIQ were found to be normally distributed, and exploratory factor analysis yielded four factors. Internal consistency of the HIQ ranged from 0.76 to 0.79, and two factors (“Implementation” and “Learning”) were significantly related to measures of Creative Achievement (Scientific—r = 0.26 and Writing—r = 0.31, respectively), suggesting concurrent validity. We found that the HIQ and its factors were related to a broad network of brain volumes including increased bilateral hippocampi, lingual gyrus, and caudal/rostral middle frontal lobe, and decreased volumes within the nucleus accumbens and regions within the default mode network (e.g., precuneus, posterior cingulate, transverse temporal lobe). The HIQ was found to be a reliable and valid measure of imagination in a cohort of normal human subjects, and was related to brain volumes previously identified as central to imagination including episodic memory retrieval (e.g., hippocampus). We also identified compelling evidence suggesting imagination

  18. Student Perceptions of Science Ability, Experiences, Expectations, and Career Choices

    Cherney, Michael; Cherney, I.

    2006-12-01

    The decision to study physics or astronomy is affected by many factors, including preferences, motivations, and expectations for success. Differing cognitive profiles contribute to the learning of science through a complex process in which intrinsic capacities are tuned both by everyday experience and by instruction. In an attempt to identify the developmental pathways and intrinsic factors that most strongly influence the choice to study science, we administered an extensive survey to a sample of 400 students. The survey questions were based on Eccles et al.’s model of achievement-related choices and findings showing that previous play experiences, spatial experiences, task beliefs, as well as perceived mathematics ability, motivational and personality characteristics affect mathematics achievement and science career choices. The perceptions of students planning a science career are compared with those planning a career in other areas. Gender differences are also discussed.

    Xiao Lan Bao; Mei Song; Jing Zhang; Yang Chen; Shun Tang Guo

    2007-01-01

    This present study investigated the ability of various soy protein hydrolysates (SPHs) in binding calcium. It was demonstrated that the amount of Ca-bound depended greatly on the SPHs obtained using different proteases, which included: neutrase,flavourzyme, protease M and pepsin. The maximum level of Ca-bound (66.9 mg/g) occurred when protease M was used to hydrolyze soy protein. Peptide fragments exhibiting high Ca-binding capacity had molecular weights of either 14.4 or 8-9 kDa. The level of Ca-bound increased linearly with the increment of carboxyl content in SPHs, and further deamidation on SPHs from protease M improved Ca-binding of the hydrolysate.

  4. Representations of Race, Gender and Ability in School Photography

    Eric Margolis

    2000-07-01

    Full Text Available This article examines photographs taken of American public school classes between the 1880's and the 1940's. Most of the images were found in two virtual archives: The American Memory site at the Library of Congress and The National Archives and Record Center. These very large photograph collections were searched for representations of race, gender, and physical ability. The photographs were compared and contrasted and analyzed for elements of hidden curricula using techniques drawn from the social sciences and humanities. It was found that these large photo collections have significant gaps and historical amnesias. Collections made under conditions of racial segregation are themselves segregated and continue to reproduce images of hierarchy and dominance. To the extent these sites function as important resources for teachers and students searching for primary source documents for history and social studies projects, the archives convey significantly biased views of the history of education and minority groups in America.

  5. Left hemispheric advantage for numerical abilities in the bottlenose dolphin.

    Kilian, Annette; von Fersen, Lorenzo; Güntürkün, Onur

    2005-02-28

    In a two-choice discrimination paradigm, a bottlenose dolphin discriminated relational dimensions between visual numerosity stimuli under monocular viewing conditions. After prior binocular acquisition of the task, two monocular test series with different number stimuli were conducted. In accordance with recent studies on visual lateralization in the bottlenose dolphin, our results revealed an overall advantage of the right visual field. Due to the complete decussation of the optic nerve fibers, this suggests a specialization of the left hemisphere for analysing relational features between stimuli as required in tests for numerical abilities. These processes are typically right hemisphere-based in other mammals (including humans) and birds. The present data provide further evidence for a general right visual field advantage in bottlenose dolphins for visual information processing. It is thus assumed that dolphins possess a unique functional architecture of their cerebral asymmetries. PMID:15686828

Research shows that the visual system is already in an advanced stage, right from the moment the baby is born, and that normal eye sight is attained at the age of 5 and continues to improve. On the other hand, attention is an flexible process, subordinated to a cognitive strategy and its relation to eye sight is only functional. The understanfing of the capacity of selective attention is necessary to the teacher or coach for it will help him/her to take decisions on how to teach, which aspects of his/her teaching should be emphasized or inhibited, in the learning process, and wich teaching strategies he/she should use.

    2010-02-01

    Spectral power distribution of trichromatic clusters of light-emitting diodes (LEDs) was optimized for rendering the highest number of colors with a perceptually noticeable gain in chroma (color saturation) out of 1269 Munsell samples. The basic tradeoffs of the number of colors rendered with increased saturation with the number of colors rendered with high fidelity and with luminous efficacy of radiation were established. High-saturation RGB clusters composed of commercially available AlGaInP and InGaN LEDs were modeled for a standard set of correlated color temperatures and the stability of the color saturation ability of the clusters against the drift of peak wavelengths was investigated.

    Moutsiana, Christina; Garrett, Neil; Clarke, Richard C; Lotto, R Beau; Blakemore, Sarah-Jayne; Sharot, Tali

    2013-10-01

    Humans show a natural tendency to discount bad news while incorporating good news into beliefs (the "good news-bad news effect"), an effect that may help explain seemingly irrational risk taking. Understanding how this bias develops with age is important because adolescents are prone to engage in risky behavior; thus, educating them about danger is crucial. We reveal a striking valence-dependent asymmetry in how belief updating develops with age. In the ages tested (9-26 y), younger age was associated with inaccurate updating of beliefs in response to undesirable information regarding vulnerability. In contrast, the ability to update beliefs accurately in response to desirable information remained relatively stable with age. This asymmetry was mediated by adequate computational use of positive but not negative estimation errors to alter beliefs. The results are important for understanding how belief formation develops and might help explain why adolescents do not respond adequately to warnings. PMID:24019466

    2007-11-01

    Full Text Available In this paper, we show how a simulated anthropomorphic robotic arm controlled by an artificial neural network can develop effective reaching and grasping behaviour through a trial and error process in which the free parameters encode the control rules which regulate the fine-grained interaction between the robot and the environment and variations of the free parameters are retained or discarded on the basis of their effects at the level of the global behaviour exhibited by the robot situated in the environment. The obtained results demonstrate how the proposed methodology allows the robot to produce effective behaviours thanks to its ability to exploit the morphological properties of the robot's body (i.e. its anthropomorphic shape, the elastic properties of its muscle-like actuators and the compliance of its actuated joints and the properties which arise from the physical interaction between the robot and the environment mediated by appropriate control rules.

  13. The artistry and ability of traditional women healers.

    Struthers, Roxanne

    2003-04-01

    In a phenomenological research study with a purposeful sample, 6 Ojibwa and Cree indigenous women healers from Canada and the United States shared their experience of being a traditional healer. Using stories obtained during open-ended, unstructured interviews, in this article I depict the lives, backgrounds, and traditional healing practices of women who, in the past, have not been afforded an opportunity to dialogue about their healing art and abilities. The methods of these women healers, their arts and their gifts, are different from those of Western conventional medicine because of dissimilar world views related to health and illness. An increased awareness of health care providers related to the ancient art of traditional healing currently practiced in communities by gifted women who provide culturally specific holistic healing and health care is essential.

    2010-01-25

    This study was initiated by the laboratories and control department of the French Health Products Safety Agency (AFSSAPS) as part of the fight against the public health problem of rising counterfeit and imitation medicines. To test the discriminating ability of Near InfraRed Spectroscopy (NIRS), worse cases scenarios were first considered for the discrimination of various pharmaceutical final products containing the same Active Pharmaceutical Ingredient (API) with different excipients, such as generics of proprietary medicinal products (PMP). Two generic databases were explored: low active strength hard capsules of Fluoxetine and high strength tablets of Ciprofloxacin. Then 4 other cases involving suspicious samples, counterfeits and imitations products were treated. In all these cases, spectral differences between samples were studied, giving access to API or excipient contents information, and eventually allowing manufacturing site identification. A chemometric background is developed to explain the optimisation methodology, consisting in the choices of appropriate pretreatments, algorithms for data exploratory analyses (unsupervised Principal Component Analysis), and data classification (supervised cluster analysis, and Soft Independent Modelling of Class Analogy). Results demonstrate the high performance of NIRS, highlighting slight differences in formulations, such as 2.5% (w/w) in API strength, 1.0% (w/w) in excipient and even coating variations (<1%, w/w) with identical contents, approaching the theoretical limits of NIRS sensitivity. All the different generic formulations were correctly discriminated and foreign PMP, constituted of formulations slightly different from the calibration ones, were also all discriminated. This publication addresses the ability of NIRS to detect counterfeits and imitations and presents the NIRS as an ideal tool to master the global threat of counterfeit drugs. PMID:20103090

    2006-06-01

    The aim of the study was to analyze the relation between motor abilities and performance in folk dances originating from the island of Hvar and modern social dances. Two groups of variables were used in a sample of 78 female students of the Teacher Training College from Split: 7 motor variables as a battery of predictors, and performance evaluation of 4 dances (2 folk dances, i.e. ciciliona and pasavijen, and 2 social dances, i.e. cha-cha-cha and rock-'n'-roll) as criterion variables. Canonical correlation analysis between the groups of variables yielded two canonical correlations of 0.94 and 0.73, with a level of significance of pdance, and the second one on explosive strength of the running type with below-average coordination and the cha-cha-cha, rock-'n'-roll and pasavijen dances. Regression analysis indicated the battery of motor variables used to be a good predictor of performance in all study dances, with multiple correlation of 0.93 in ciciliona, 0.84 in pasavijen, 0.75 in rock-'n'-roll and 0.73 in cha-cha-cha. In ciciliona and pasavijen, the latent dance structure is predominantly explained by coordination, in rock-'n'-roll by explosive strength, and in cha-cha-cha by explosive strength and speed. Discriminative analysis revealed the general dance performance to mostly depend on coordination, then on explosive strength, and to a lesser extent on speed (movement frequency). Dance is an irreplaceable educational tool in kinesiologic education of female students, among others for its considerable contribution to the development and maintenance of basic motor abilities.

  17. Undergraduate nursing students' perceptions regarding factors that affect math abilities

    Pyo, Katrina A.

    2011-07-01

    A review of the nursing literature reveals many undergraduate nursing students lack proficiency with basic mathematical skills, those necessary for safe medication preparation and administration. Few studies exploring the phenomenon from the undergraduate nursing student perspective are reported in the nursing literature. The purpose of this study was to explore undergraduate nursing students’ perceptions of math abilities, factors that affect math abilities, the use of math in nursing, and the extent to which specific math skills were addressed throughout a nursing curriculum. Polya’s Model for Problem Solving and the Bloom’s Taxonomy of Educational Objectives, Affective Domain served as the theoretical background for the study. Qualitative and quantitative methods were utilized to obtain data from a purposive sample of undergraduate nursing students from a private university in western Pennsylvania. Participants were selected based on the proficiency level with math skills, as determined by a score on the Elsevier’s HESI™ Admission Assessment (A2) Exam, Math Portion. Ten students from the “Excellent” benchmark group and eleven students from the “Needing Additional Assistance or Improvement” benchmark group participated in one-on-one, semi-structured interviews, and completed a 25-item, 4-point Likert scale survey that rated confidence levels with specific math skills and the extent to which these skills were perceived to be addressed in the nursing curriculum. Responses from the two benchmark groups were compared and contrasted. Eight themes emerged from the qualitative data. Findings related to mathematical approach and confidence levels with specific math skills were determined to be statistically significant.

The major categories of diagnostic errors include: (1) no-fault errors--the disease is present but not detected; (2) system errors--a diagnosis is delayed or missed because of the imperfection in the health care system; and (3) cognitive errors--a misdiagnosis from faulty data collection or interpretation, flawed reasoning, or incomplete knowledge. Approximately one third of patient problems are mismanaged because of diagnostic errors. Part of the solution lies in improving the diagnostic skills and critical thinking abilities of physicians as they progress through medical school and residency training. However, this task is challenging since both medical problem-solving and the learning environments are complex and not easily understood. There are many interacting variables including the motivation of the medical student (e.g. deep versus surface learning), the acquisition and evolution of declarative and conditional knowledge (e.g. reduced, dispersed, elaborated, scheme, and scripted), problem-solving strategies (e.g. procedural knowledge-guessing, hypothetical deductive, scheme inductive, and pattern recognition), curricular models (e.g. apprenticeship, discipline-based, body system-based, case-based, clinical presentation-based), teaching strategies (e.g. teaching general to specific or specific to general), the presented learning opportunities (PBL versus scheme inductive PBL), and the nature of the learning environment (e.g. modeling critical thinking and expert problem-solving). This paper elaborates on how novices differ from experts and how novices can be educated in a manner that enhances their level of expertise and diagnostic abilities as they progress through several years of medical training.

    Full Text Available Specific Language impairment (SLI is a heritable neurodevelopmental disorder diagnosed when a child has difficulties learning to produce and/or understand speech for no apparent reason (Bishop et al., 2012. The verbal difficulties of children with SLI have been largely documented, and a growing number of studies suggest that these children may also have difficulties in processing non-verbal complex auditory stimuli (Brandt et al., 2012; Corriveau et al., 2007. In a recent study, we reported that a large proportion of children with SLI present deficits in music perception (Planchou et al, submitted. Little is known, however, about the singing abilities of children with SLI. In order to investigate whether or not the impairments in expressive language extend to the musical domain, we assessed singing abilities in 8 children with SLI and 15 children with Typical Language Development (TLD matched for age and non-verbal intelligence. To this aim, we designed a ludic activity consisting of two singing tasks: a pitch-matching and a melodic reproduction task. In the pitch-matching task, the children were requested to sing single notes. In the melodic reproduction task, children were asked to sing short melodies that were either familiar (FAM-SONG and FAM-TUNE conditions or unfamiliar (UNFAM-TUNE condition. The analysis showed that children with SLI were impaired in the pitch-matching task, with a mean pitch error of 250 cents (mean pitch error for children with TLD: 154 cents. In the melodic reproduction task, we asked 30 healthy adults to rate the quality of the sung productions of the children on a continuous rating scale. The results revealed that singing of children with SLI received lower mean ratings than the children with TLD. Our findings thus indicate that children with SLI showed impairments in musical production and are discussed in light of a general auditory-motor dysfunction in children with SLI.

    Full Text Available The main goal of hybrid wheat breeding is the identification of parents with high specific combining ability for grain yield and other agronomic traits. This kind of data facilitate the development of hybrid combinations with high level of heterosis in first filial generation (F1 generation. The use of species from the hexaploid wheat group (e.g. Triticum spelta L. Triticum compactum HOST... is representing an opportunity for the increase of heterosis level in the germplasm of common wheat (Triticum aestivum L.. The study of combining ability and heterosis effect in hexaploid wheat group was carried out using crosses between thirteen inbred lines of common wheat (6 lines x 7 testers and inter-species crosses (T. aestivum L. × T. spelta L., T. aestivum L. × T. compactum HOST, T. aestivum L. × T. sphaerococcum PERCIV., T. aestivum L. × T. macha DEKAPR. et MENABDE, T. aestivum L. × T. petropavlovskyi UDACZ. et MIGUSCH, T. aestivum L. × T. vavilovii (THUM.

The experiment was carried out in a randomized block design with four replications. The 43 interspecies F1 hybrids were tested on the same location in the season 2011/12 and the experiment was designed as an randomized block with three replications. The results were analyzed using statistical package AGROBASE generation II and STATGRAPHICS Centurion XVI. The analysis of variance was significant for both, GCA and SCA variances (P < 0,01. Generally, SCA variances were lower than GCA variances. We could state, that the improvement of heterosis level in the common wheat germplasm through the use of relatives with the same genome (genome BAD is possible. As an example we can point out the interspecies F1 hybrid between common wheat variety Garcia and an accession of the Triticum sphaerococcum PERCIV. species (accession number 01C0201227.

    The PWWP domain was first identified as a structural motif of 100-130 amino acids in the WHSC1 protein and predicted to be a protein-protein interaction domain. It belongs to the Tudor domain 'Royal Family', which consists of Tudor, chromodomain, MBT and PWWP domains. While Tudor, chromodomain and MBT domains have long been known to bind methylated histones, PWWP was shown to exhibit histone binding ability only until recently. The PWWP domain has been shown to be a DNA binding domain, but sequence analysis and previous structural studies show that the PWWP domain exhibits significant similarity to other 'Royal Family' members, implying that the PWWP domain has the potential to bind histones. In order to further explore the function of the PWWP domain, we used the protein family approach to determine the crystal structures of the PWWP domains from seven different human proteins. Our fluorescence polarization binding studies show that PWWP domains have weak histone binding ability, which is also confirmed by our NMR titration experiments. Furthermore, we determined the crystal structures of the BRPF1 PWWP domain in complex with H3K36me3, and HDGF2 PWWP domain in complex with H3K79me3 and H4K20me3. PWWP proteins constitute a new family of methyl lysine histone binders. The PWWP domain consists of three motifs: a canonical {beta}-barrel core, an insertion motif between the second and third {beta}-strands and a C-terminal {alpha}-helix bundle. Both the canonical {beta}-barrel core and the insertion motif are directly involved in histone binding. The PWWP domain has been previously shown to be a DNA binding domain. Therefore, the PWWP domain exhibits dual functions: binding both DNA and methyllysine histones.

    A lysing-bacterium DC10, isolated from Dianchi Lake of Yunnan Province, was characterized to be Pseudomonas sp. It was able to lyse some algae well, such as Microcystis viridis, Selenastrum capricornutum, and so on. In this study, it was shown that the bacterium lysed the algae by releasing a substance; the best lytic effects were achieved at Iow temperatures and in the dark. Different concentrations of CaCI2 and NaNO3 influenced the lytic effects;the ability to lyse algae decreased in the following order: pH 4 > pH 9 > pH 7 > pH 5.5. It was significant to develop a special technology with this kind of bacterium for controlling the bloomforming planktonic microalgae.

A questionnaire concerning their daily activities, quality of life, pain intensity, sick-leave level, and their work state was filled out by all patients before starting the assessment and at a 1-year follow-up. The results from the assessment period and the multiprofessional team decision of the patient’s working ability were compared with the actual working rate after 1 year. The follow-up showed a significant reduction of sick leave and a higher level of activity (P < 0.001. One year after the initial evaluation, 40% showed a reduction in sickness benefit level and 12% resumed full-time work. However, the team evaluation of the patient’s work ability did not correlate to predict the actual outcome. The patient’s pain intensity, life satisfaction, gender, age, ethnic background, and time absent from work before the start of the evaluation showed no correlation to reduction on time on sickness benefit level. These parameters could not be used as predictors in this study.Keywords: health, multiprofessional team evaluation, long-standing pain

  7. Serum glutamine, set-shifting ability and anorexia nervosa

    2010-06-01

    Full Text Available Abstract Background Set-shifting is impaired in people with anorexia nervosa (AN, but the underlying physiological and biochemical processes are unclear. Animal studies have established that glutamatergic pathways in the prefrontal cortex play an important role in set-shifting ability. However, it is not yet understood whether levels of serum glutamatergic amino acids are associated with set-shifting performance in humans. The aim of this study was to determine whether serum concentrations of amino acids related to glutamatergic neurotransmission (glutamine, glutamate, glycine, l-serine, d-serine are associated with set-shifting ability in people with acute AN and those after recovery. Methods Serum concentrations of glutamatergic amino acids were measured in 27 women with current AN (AN group, 18 women recovered from AN (ANRec group and 28 age-matched healthy controls (HC group. Set-shifting was measured using the Wisconsin Card Sorting Test (WCST and the Trail Making Task (TMT. Dimensional measures of psychopathology were used, including the Eating Disorder Examination Questionnaire (EDEQ, the Maudsley Obsessive-Compulsive Inventory (MOCI and the Hospital Anxiety and Depression Scale (HADS. Results Serum glutamine concentrations in the AN group (1,310.2 ± 265.6 μM, mean ± SD were significantly higher (by approximately 20% than those in the HC group (1,102.9 ± 152.7 μM, mean ± SD (F(2, 70 = 6.3, P = 0.003, 95% CI 61.2 to 353.4. Concentrations of serum glutamine were positively associated with markers of the illness severity: a negative correlation was present between serum glutamine concentrations and body mass index (BMI and lowest BMI and a positive correlation was found between duration of illness and EDEQ. The AN group showed significantly impaired set shifting in the WCST, both total errors, and perseverative errors. In the AN group, there were no correlations between serum glutamine concentrations and set shifting. Conclusions Serum

  8. Pragmatics abilities in narrative production: a cross-disorder comparison.

    Norbury, Courtenay Frazier; Gemmell, Tracey; Paul, Rhea

    2014-05-01

    We aimed to disentangle contributions of socio-pragmatic and structural language deficits to narrative competence by comparing the narratives of children with autism spectrum disorder (ASD; n = 25), non-autistic children with language impairments (LI; n = 23), and children with typical development (TD; n = 27). Groups were matched for age (6½ to 15 years; mean: 10;6) and non-verbal ability; ASD and TD groups were matched on standardized language scores. Despite distinct clinical presentation, children with ASD and LI produced similarly simple narratives that lacked semantic richness and omitted important story elements, when compared to TD peers. Pragmatic errors were common across groups. Within the LI group, pragmatic errors were negatively correlated with story macrostructure scores and with an index of semantic-pragmatic relevance. For the group with ASD, pragmatic errors consisted of comments that, though extraneous, did not detract from the gist of the narrative. These findings underline the importance of both language and socio-pragmatic skill for producing coherent, appropriate narratives. PMID:23632039

  9. How to Improve the Ability of English Reading

    2003-01-01

    Considering the present situation, the aim of English teaching in middle schools in our country, according to the teaching syllabus, is to train the students to listen, speak, read and write ; to lay particular emphasis on the students’ reading skill so as to pave the way for their further learning and using the language properly. How can the readers make improvements in reading? There are many skills to improve one’s ability of reading comprehension. I. The knowledge of words. One of the most important skills in reading is the knowledge of word. The number of the words you know determines the difficulty and complexity of the material you can read and understand. If you have an extremely limited reading vocabulary, you will be able to read only very simple material. Obviously, vocabulary forms a stumbling block for the poor reader. The more words you memorize, the faster you read the article. So, it is necessary to memorize words as much as you can.

  10. How reflective practice improves nurses' critical thinking ability.

    Cirocco, Maria

    2007-01-01

    Purposeful reflection is consistent with adult learning theory. It is known to lead to a deeper understanding of issues and to develop judgment and skill. Required by law to ensure members' competence in their professional practice, the College of Nurses of Ontario recommends and has developed a tool for evaluating reflective practice. The tool focuses on key attributes said to be demonstrated by competent practitioners, including critical thinking (CT) and job knowledge. This study aimed to determine whether nurses engage in reflective practice and whether they perceive that it enhances their CT ability. Surveys were sent to 60 gastroenterology nurses at a large teaching hospital; 34 surveys were anonymously returned. All respondents engaged in reflective practice, and 24 reported using the college's tool. Nineteen respondents strongly agreed that their nursing practice had improved as a result. Critical thinking is difficult to assess because of a lack of clear-cut performance criteria. Improvement of CT was difficult to evaluate from the responses, even though all respondents participated in reflective practice. Both CT and reflective practice need to be better defined in order to examine and explain their relationship. PMID:18156956

  11. Inattentional Blindness and Individual Differences in Cognitive Abilities.

    Carina Kreitz

    Full Text Available People sometimes fail to notice salient unexpected objects when their attention is otherwise occupied, a phenomenon known as inattentional blindness. To explore individual differences in inattentional blindness, we employed both static and dynamic tasks that either presented the unexpected object away from the focus of attention (spatial or near the focus of attention (central. We hypothesized that noticing in central tasks might be driven by the availability of cognitive resources like working memory, and that noticing in spatial tasks might be driven by the limits on spatial attention like attention breadth. However, none of the cognitive measures predicted noticing in the dynamic central task or in either the static or dynamic spatial task. Only in the central static task did working memory capacity predict noticing, and that relationship was fairly weak. Furthermore, whether or not participants noticed an unexpected object in a static task was only weakly associated with their odds of noticing an unexpected object in a dynamic task. Taken together, our results are largely consistent with the notion that noticing unexpected objects is driven more by stochastic processes common to all people than by stable individual differences in cognitive abilities.

  12. Classical and Molecular Genetic Research on General Cognitive Ability.

    McGue, Matt; Gottesman, Irving I

    2015-01-01

    Arguably, no psychological variable has received more attention from behavioral geneticists than what has been called "general cognitive ability" (as well as "general intelligence" or "g"), and for good reason. GCA has a rich correlational network, implying that it may play an important role in multiple domains of functioning. GCA is highly correlated with various indicators of educational attainment, yet its predictive utility is not limited to academic achievement. It is also correlated with work performance, navigating the complexities of everyday life, the absence of various social pathologies (such as criminal convictions), and even health and mortality. Although the causal basis for these associations is not always known, it is nonetheless the case that research on GCA has the potential to provide insights into the origins of a wide range of important social outcomes. In this essay, our discussion of why GCA is considered a fundamentally important dimension of behavior on which humans differ is followed by a look at behavioral genetics research on CGA. We summarize behavioral genetics research that has sought to identify and quantify the total contributions of genetic and environmental factors to individual differences in GCA as well as molecular genetic research that has sought to identify genetic variants that underlie inherited effects.

    Full Text Available How the individual differences prime different learning process is well addressed in literature. But, what is missing from these analyses is how learners with different identity styles approach reading and writing skills and if different identity styles can predict differentiated language performance. The present study aims at investigating the relationship between identity styles, and reading/writing skills of Iranian intermediate female EFL learners. One the basis of the results of Nelson language proficiency test, 120 participants were selected to participate in this research. Participants' answers to Berzonsky's Identity Style Inventory (ISI3 and reading and writing parts of Preliminary English Test were analyzed. The results indicated that informational and normative identity styles were found to be positively correlated and diffuse-avoidant style was negatively correlated with reading and writing abilities whereas commitment identity didn't bear any significant relationships. The findings also indicated that informational style acted as the best predictor of these skills. Implications for language teachers are suggested.Keywords: Reading and writing skills, Informational identity styles, normative identity styles, Diffuse avoidant style, Commitment style 

  14. Polyelectrolytes Ability in Reducing Atrazine Concentration in Water: Surface Effects

    Mohamad Faiz Mohd Amin

    2014-01-01

    Full Text Available This paper reports on the direct ability of two positively charged organic polyelectrolytes (natural-based and synthetic to reduce the atrazine concentration in water. The adsorption study was set up using multiple glass vessels with different polymer dosing levels followed by ultrafiltration with a 1 kDa membrane. The addition of polymers exhibited a capability in reducing the atrazine concentration up to a maximum of 60% in surface-to-volume ratio experiments. In the beginning, the theoretical L-type of the isotherm of Giles’ classification was expected with an increase in the dosage of the polymer. However, in this study, the conventional type of isotherm was not observed. It was found that the adsorption of the cationic polymer on the negatively charged glass surface was necessary and influential for the removal of atrazine. Surface-to-volume ratio adsorption experiments were performed to elucidate the mechanisms and the polymer configuration. The glass surface area was determined to be a limiting parameter in the adsorption mechanism.

  15. Reduction of nitroxides and radioprotective ability in glioblastoma cells

    Electron spin resonance (ESR) analyses were performed to clarify whether glioblastoma cells scavenge hydroxyl radicals (·OH) generated by x-ray irradiation. The rate of bioreduction of nitroxides by three human glioblastoma cells was also evaluated by the same technique and compared with their x-ray sensitivity. Aerated culture media containing 200 mM of 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) with or without U87MG cells were irradiated with x-rays at a dose of 20 Gy. ESR was measured immediately after each irradiation. Continuous changes of the ESR spectra of 4-hydroxy-2,2,6,6-tetramethylpiperidine-1-oxyl (Tempol) were analyzed in cell suspensions of TK1, U87MG, and A172 at a concentration of 1.0 x 107 cells/ml containing 5 μM Tempol. As a result, the signal of DMPO-OH in the U87MG cell suspension decayed faster than that in the control culture media without cells, and the rate of bioreduction of Tempol in each glioblastoma cell suspension was correlated with the x-ray sensitivity defined from the colony-forming assay in those cell lines. It was indicated that the resistance of glioblastoma cells to ionizing radiation could be closely related to their ability to scavenge radical species generated by ionizing radiation. (author)

    2014-03-01

    Full Text Available Aiming to estimate the combining ability in tropical and temperate popcorn (Zea mays L. var. everta Sturt. lines using multivariate analysis, ten popcorn lines were crossed in a complete diallel without reciprocals and the lines and hybrids were tested in two randomized complete block experiments with three replicates. Data were subjected to univariate and multivariate ANOVA, principal component analysis, and univariate and multivariate diallel analysis. For multivariate diallel analysis, variables were divided into group I (grain yield, mean weight of ears with grains, popping expansion, mean number of ears per plant, and final stand and group II (days to silking, plant height, first ear height, and lodged or broken plants. The P2 line had positive values for agronomic traits related to yield and popping expansion for group I, whereas the P4 line had fewer days to silking and lodged or broken plants for group II. Regarding the hybrids, P2 x P7 exhibited favorable values for most of the analyzed variables and had potential for recommendation. The multivariate diallel analysis can be useful in popcorn genetic improvement programs, particularly when directed toward the best cross combinations, where the objective is to simultaneously obtain genetic gains in multiple traits.

  17. Emotional intelligence as a cognitive-emotional ability

    Andreja Avsec

    2003-06-01

    Full Text Available In the article we analyse Mayer and Salovey's model of emotional intelligence. The authors have defined it for the first time in the 90's, delimited its relation to the social intelligence and formed two tests for its measurement, which are unique published tests of their kind. The authors try to separate their approach towards the measurement of emotional intelligence from the self-report measures and from defining emotional intelligence as a set of personality traits. Besides the measurement of emotional intelligence with the tests of maximum performance, authors try to prove that correlation between emotional abilities indicate similar hierarchical structure as is characteristic for other kinds of intelligence. Since the first test for measuring the emotional intelligence was published in 1997 and there have been no other published tests of this kind yet, it is very difficult to evaluate its metric characteristics and the validity of the model. Anyhow, in defining and measuring the emotional intelligence researchers face similar problems as in social intelligence research.

    Full Text Available The ability to interact with other people hinges crucially on the possibility to anticipate how their actions would unfold. Recent evidence suggests that a similar skill may be grounded on the fact that we perform an action differently if different intentions lead it. Human observers can detect these differences and use them to predict the purpose leading the action. Although intention reading from movement observation is receiving a growing interest in research, the currently applied experimental paradigms have important limitations. Here, we describe a new approach to study intention understanding that takes advantage of robots, and especially of humanoid robots. We posit that this choice may overcome the drawbacks of previous methods, by guaranteeing the ideal trade-off between controllability and naturalness of the interactive scenario. Robots indeed can establish an interaction in a controlled manner, while sharing the same action space and guaranteeing contingent behaviors. To conclude, we discuss the advantages of this research strategy and the aspects to be taken in consideration when attempting to define which human (and robot motion features allow for intention reading during social interactive tasks.
