    Falcon Dario Restrepo Ramos

    2015-01-01

    Full Text Available This literature review aims to analyze previous studies that address the incidental learning of vocabulary in second language acquisition. The articles included in this literature review look into the understanding of vocabulary learning through incidental means, the relationship of reading and incidental vocabulary learning, and the strategies and tasks that promote the incidental learning of vocabulary. The findings show that L2 learners develop much of their vocabulary by incidental means through exposure to words in informative contexts. Moreover, this exposure is promoted by reading, and enhanced through multimodal glosses. Further research may focus on listening for higher lexical retention rates, the circumstances that allow incidental learning of multi-word phrases and collocations, and the use of technology-based methods for incidental vocabulary acquisition.

    2010-11-01

    Two experiments examined whether the age of acquisition (AoA) of a concept influences the speed at which native English speakers are able to name pictures using a newly acquired second language (L2) vocabulary. In Experiment 1, participants were taught L2 words associated with pictures. In Experiment 2 a second group of participants were taught the same words associated with L1 translations. Following training both groups performed a picture naming task in which they were asked to name pictures using the newly acquired words. Significant AoA effects were observed only in Experiment 1, in that participants were faster at naming pictures representing early acquired relative to late acquired concepts. The results suggest that the AoA of a concept can exert influence over processing which is independent of the AoA of the word form. The results also indicate that different training methods may lead to qualitative differences in the nature of the links formed between words and concepts during the earliest stages of second language learning.

    This study examined whether English-only vocabulary instruction or English vocabulary instruction enhanced with Spanish bridging produced greater word learning in young Spanish-speaking children learning English during a storybook reading intervention while considering individual language characteristics. Twenty-two Spanish-speaking children learning English (ages 4-6) who participated in a summer education program for migrant families were randomly assigned to receive 2 weeks of each instruction: (a) word expansions in English or (b) English readings with word expansions in Spanish. Researcher-created measures of target vocabulary were administered, as were English and Spanish standardized measures of language proficiency and vocabulary. Results revealed significant improvement in naming, receptive knowledge, and expressive definitions for those children who received Spanish bridging. Spanish expansions produced the greatest gains in the children's use of expressive definitions. Initial language proficiency in both languages was found to affect participants' gains from intervention, as those with limited skills in both languages showed significantly less vocabulary growth than those with strong skills in Spanish. Additional benefits to using Spanish expansions in vocabulary instruction were observed. Future research should explore additional ways of enhancing the vocabulary growth of children with limited skills in both languages in order to support and strengthen the child's first language and promote second language acquisition.

  1. The Function of Negotiation in Iranian EFL Students’ Vocabulary Acquisition

    Full Text Available Negotiation is believed to play a key role in language learning in general and vocabulary learning in particular. The present study aimed at investigating the effect of types of instructions (negotiation, non-negotiation, or in isolation on learning and recalling of new words by Iranian learners. Using a quasi-experimental research design, 39 EFL students of a secondary school were sampled and assigned into three experimental groups: the input plus negotiated group (IPN, the input without negotiated group (IWN, and the elaborative, un-instructed input group (EUI. The first group had the chance for negotiated interaction; the second one received the input without any negotiation with their instructor and the last group received elaborative input without any interaction with their teachers. The groups were rated on their degree of comprehension and the acquisition of vocabulary items. The results revealed that negotiation had a non-significant effect over non-negotiation tasks. However, the results indicated that negotiation was significantly effective against un-instruction task. Thus, in acquisition and retention of new vocabulary, IPN group was not significantly different than IWN group, but they outperformed those learners who used their own strategy to learn new words (EUI.

  2. Neural changes underlying early stages of L2 vocabulary acquisition.

    2016-11-01

    Research has shown neural changes following second language (L2) acquisition after weeks or months of instruction. But are such changes detectable even earlier than previously shown? The present study examines the electrophysiological changes underlying the earliest stages of second language vocabulary acquisition by recording event-related potentials (ERPs) within the first week of learning. Adult native English speakers with no previous Spanish experience completed less than four hours of Spanish vocabulary training, with pre- and post-training ERPs recorded to a backward translation task. Results indicate that beginning L2 learners show rapid neural changes following learning, manifested in changes to the N400 - an ERP component sensitive to lexicosemantic processing and degree of L2 proficiency. Specifically, learners in early stages of L2 acquisition show growth in N400 amplitude to L2 words following learning as well as a backward translation N400 priming effect that was absent pre-training. These results were shown within days of minimal L2 training, suggesting that the neural changes captured during adult second language acquisition are more rapid than previously shown. Such findings are consistent with models of early stages of bilingualism in adult learners of L2 (e.g. Kroll and Stewart's RHM) and reinforce the use of ERP measures to assess L2 learning.

  5. BUSINESS ENGLISH WORD GAMES – A WELCOMED VOCABULARY TEACHING TECHNIQUE

    Full Text Available Introducing vocabulary has never been very problematic nor a doubt generating aspect in teaching a language, at least not in respect of what has to be done actually along this part of the lesson or how this stage should be approached. It cannot be said that it has ever been too much of a challenge, but rather a simple and straightforward phase in the economy of the English class. Business English vocabulary teaching methods have to make allowance for the specificity of the field, though. Thus, much consideration has to be given to the way Business English lexical units are introduced so that the technique used could produce the desired results into the students: acquisition of specific terminology, assimilation of meanings and development of skills that shall ensure accurate usage of the terms in the future. After an experimental semester, most adequate class approaches to serve the purposes abovementioned proved to be – rather non-academic, it may be argued – the word games. The current study presents the detailed steps of two distinct teaching methods used and the comparative results obtained with the two groups of students submitted to the experiment. Along the Business English courses in one semester, there were four vocabulary introduction lessons. The nonconformist technique of word games was implemented to one of the two groups of students while the other was taught the regular style. The comparative study focused on several aspects, from the observation of the class reactions and participation along the process of teaching, i.e. response to the didactic process during each class, to the checking of the effects of both types of implementation, namely assessing assimilation of the previously taught material in terms of knowledge of vocabulary and correct interpretation, by random tests and by final test results. If teaching methodologies regularly claim that the general to particular approach is the most effective, here a vice

A KET test was administered and based on its results, two classes were selected as the homogenous ones, which were randomly assigned into the vocabulary flooding (experimental and no vocabulary flooding (control groups, each with 30 students. After the vocabulary recognition pretest, supplementary vocabulary teaching was used as the treatment in both groups. In the Experimental group, the target words were presented and practiced in flooding form, that is, in six or more sentences, while in the Control group, students were taught and practiced in only one sentence. After the treatment, two posttests (immediate and delayed were conducted in both groups. The results of the One-way within-subjects and between-subjects Repeated-Measures ANOVA revealed that there were statistically significant differences within and between the experimental and control groups in the three vocabulary recognition tests. It was found that the participants’ receptive vocabulary knowledge was improved in the experimental group as a result of using vocabulary flooding technique. The implications are provided for the syllabus designers, textbook writers and EFL teachers.

  10. Vocabulary Acquisition for Future Nursing Staff: authenticity in the classroom

    Directory of Open Access Journals (Sweden)

    2015-11-01

    Full Text Available Research suggests that many ESL teachers either modify or supplement the set textbooks they use in class, or develop their own materials for classroom use. Indeed, in recent years, the internet in particular has opened up a rich and at times perhaps baffling array of resources for those ESL practitioners who wish to incorporate authentic materials into their teaching. While the benefits of authentic materials are well-documented, their use is, however, not entirely unproblematic, and as research into the field of material (authentic or otherwise development grows, this raises a number of issues as to the form these materials should take and how they can best be employed. This article presents a set of vocabulary building activities for future nursing staff; these activities are in use at the Faculty of Health Sciences in Maribor. The article explains the rationale behind them in light of the theoretical framework of language acquisition that underpins them.

    2017-09-21

    Preschoolers' vocabulary acquisition sets the stage for later reading ability and school achievement. This study examined the role of socioeconomic status (SES) and the quality of the home environment of seventy-seven Chilean majority and Mapuche minority families from low and lower-middle-class backgrounds in explaining individual differences in vocabulary acquisition of their three-and-a-half-year-old children. Additionally, we investigated whether the relation between SES and receptive and expressive vocabulary was mediated by the quality of the home environment as the Family Investment Model suggests. The quality of the home environment significantly predicted receptive and expressive vocabulary above and beyond ethnicity, SES, parental caregiver status, and quantity of daycare. Furthermore, the quality of the home environment mediated the relation between SES and expressive and receptive vocabulary acquisition.

    Kim, Young-Suk Grace

    2017-10-01

    The role of working memory in vocabulary acquisition has been well established in the literature. In this study, we proposed and empirically tested the multicomponent view of vocabulary acquisition, which states that multiple language and cognitive skills are involved to facilitate phonological and semantic representations needed for vocabulary acquisition. Working memory and attention were hypothesized to be directly and indirectly related to vocabulary, whereas inference and morphosyntactic knowledge were hypothesized to be directly related to vocabulary (measured by the Picture Vocabulary Test of the Woodcock-Johnson III battery). Results from 262 kindergartners using path analysis revealed that all the multiple cognitive and language skills were directly related to vocabulary after controlling for age, gender, racial/ethnic backgrounds, socioeconomic status (as measured by free or reduced-price lunch eligibility), and each other. Furthermore, working memory and attention also made indirect contributions via inference and morphosyntactic knowledge. Total effects (beta weights), accounting for direct and indirect effects, were .33 for working memory, .23 for attention, .18 for inference, and .18 for morphosyntactic knowledge. These results indicate that although working memory is important, contributions of other language and cognitive skills should be considered in vocabulary acquisition. Theoretical and practical implications are discussed. Copyright © 2017 Elsevier Inc. All rights reserved.

    2015-01-01

    Vocabulary plays a prominent role in the second language acquisition of high school students. The new Curriculum Standard requires that students should master as many as 3300 words as well as 400-500 useful expressions and fixed collocation, which brings a great challenge to our vocabulary teaching in high schools. The present study aims at investigating differential effects of explicit and implicit enhancement on L2 vocabulary acquisition in senor high school in order to help teachers realize how to select and apply the most suitable way to the vocabulary instruction so as to improve students’ efficiency in the vocabulary retention.Based on the theory of depth of information processing by Craik and Lockhart (1972), the thesis mainly deals with 3 main aspects just as follows:First,the different effects of explicit enhancement and implicit enhancement on high school students’ vocabulary acquisition. Second, the different effects of explicit enhancement and implicit enhancement on the receptive vocabulary knowledge and productive knowledge.Third,the different effects on vocabulary retention, especially in short-term memory and long-term memory.

    This study examines how STEM (science, technology, engineering, and mathematics) inquiry-based learning through a hands-on engineering design can be beneficial in helping students acquire academic vocabulary. This research took place in a second grade dual- language classroom in a public, suburban elementary school. English language learners, students who speak Spanish at home, and native English speakers were evaluated in this study. Each day, students were presented with a general academic vocabulary focus word during an engineering design challenge. Vocabulary pre-tests and post-tests as well as observation field notes were used to evaluate the student's growth in reading and defining the focus academic vocabulary words. A quiz and KSB (knowledge and skill builder) packet were used to evaluate students' knowledge of science and math content and engineering design. The results of this study indicate that engineering design is an effective means for teaching academic vocabulary to students with varying levels of English proficiency.

    Technical medical terms are complicated to be correctly understood by non-experts. Vocabulary, associating technical terms with layman expressions, can help in increasing the readability of technical texts and their understanding. The purpose of our work is to build this kind of vocabulary. We propose to exploit the notion of reformulation following two methods: extraction of abbreviations and of reformulations with specific markers. The segments associated thanks to these methods are aligned with medical terminologies. Our results allow to cover over 9,000 medical terms and show precision of extractions between 0.24 and 0.98. The results and analyzed and compared with the existing work.

    In a previous experiment [P. L. Scilley, "Evaluation of a vibrotactile auditory prosthetic device for the profoundly deaf," unpublished Masters thesis, Queen's University, Kingston, Canada (1980)] two normal subjects learned to identify 70 and 150 words, respectively, using the Queen's Tactile Vocoder. In the present experiment, the most advanced subject continued word learning until a tactile vocabulary of 250 words was acquired. At this point randomized tests were given to obtain an indication of final performance level. From these data conditional probabilities of correct response for each stimulus word and significant confusions were obtained, which provides insight into the advantages and present limitations of the tactile vocoder.

    2013-01-01

    First language acquisition requires relatively little effort compared to foreign language acquisition and happens more naturally through informal learning. Informal exposure can also benefit foreign language learning, although evidence for this has been limited to speech perception and production. An important question is whether informal exposure to spoken foreign language also leads to vocabulary learning through the creation of form-meaning links. Here we tested the impact of exposure to foreign language words presented with pictures in an incidental learning phase on subsequent explicit foreign language learning. In the explicit learning phase, we asked adults to learn translation equivalents of foreign language words, some of which had appeared in the incidental learning phase. Results revealed rapid learning of the foreign language words in the incidental learning phase showing that informal exposure to multi-modal foreign language leads to foreign language vocabulary acquisition. The creation of form-meaning links during the incidental learning phase is discussed.

    We investigated the impact of emotions on learning vocabulary in an unfamiliar language to better understand affective influences in foreign language acquisition. Seventy native English speakers learned new vocabulary in either a negative or a neutral emotional state. Participants also completed two sets of working memory tasks to examine the potential mediating role of working memory. Results revealed that participants exposed to negative stimuli exhibited difficulty in retrieving and correctly pairing English words with Indonesian words, as reflected in a lower performance on the prompted recall tests and the free recall measure. Emotional induction did not change working memory scores from pre to post manipulation. This suggests working memory could not explain the reduced vocabulary learning in the negative group. We argue that negative mood can adversely affect language learning by suppressing aspects of native-language processing and impeding form-meaning mapping with second language words.

  17. PROTOTYPIC EFFECTS IN VOCABULARY ACQUISITION: EVIDENCE FROM CHINESE LEARNERS OF ENGLISH

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    This paper is based on the assumption that semantic categories vary from one language to another and prototypes of semantic categories are culture-specific. Prototypicality has its effects in acquisition of second foreign language vocabulary. The author hypothesizes that focal member words and basic level words are acquired earlier than non-focal member words and words on other levels of lexical hierarchies when prototypes of the target language correspond to those of the mother tongue in the same semantic categories. The results of a vocabulary test on beginner, intermediate and advanced learners of English as foreign language confirm the hypothesis. The paper concludes that learning a second foreign language means, to an extent, learning to categorize the worm in a different way, and prototypic effects should be given due attention in vocabulary instruction.

    Full Text Available The paper suggests effective techniques to improve the vocabulary of the students in English as a Second Language context based on an experimental study. The study was conducted in India (South Asia, in an Engineering college for freshmen in the age group of eighteen to nineteen years. The paper makes a comparison of two vocabulary teaching strategies and the results show that explicit vocabulary teaching is more effective than implicit vocabulary teaching. The experimental group also showed greater involvement as they enjoyed doing reading and vocabulary exercises than the control group that did only reading activities. The study makes an important contribution to the existing research as it recommends focused vocabulary teaching by suggesting various techniques for teaching vocabulary.

  3. Neural Stimulation Has a Long-Term Effect on Foreign Vocabulary Acquisition.

    Pasqualotto, Achille; Kobanbay, Begüm; Proulx, Michael J

    2015-01-01

    Acquisition of a foreign language is a challenging task that is becoming increasingly more important in the world nowadays. There is evidence suggesting that the frontal and temporal cortices are involved in language processing and comprehension, but it is still unknown whether foreign language acquisition recruits additional cortical areas in a causal manner. For the first time, we used transcranial random noise stimulation on the frontal and parietal brain areas, in order to compare its effect on the acquisition of unknown foreign words and a sham, or placebo, condition was also included. This type of noninvasive neural stimulation enhances cortical activity by boosting the spontaneous activity of neurons. Foreign vocabulary acquisition was tested both immediately and seven days after the stimulation. We found that stimulation on the posterior parietal, but not the dorsolateral prefrontal cortex or sham stimulation, significantly improved the memory performance in the long term. These results suggest that the posterior parietal cortex is directly involved in acquisition of foreign vocabulary, thus extending the "linguistic network" to this area.

    Full Text Available The present study was an attempt to look into the effect of collaborative learning on the learners’ improvement in vocabulary learning. Moreover, the learners’ attitudes about vocabulary learning were taken into account as well. The study was conducted with the participation of 30 intermediate Iranian EFL (English as a foreign language learners, who were studying in a private language institute. To collect the data, OPT (Oxford Placement Test was applied to check the learners’ proficiency level and meet the homogeneity requirements. Then, the learners took the vocabulary pre- and post-test to check the effectiveness of treatment sessions on the learners’ vocabulary learning. Semi-structured interview was also done to investigate the learners’ awareness regarding learning vocabularies before and after the treatment sessions. Findings showed that the applied collaborative techniques, i.e. word-webbing and snowball techniques paved the way for the experimental group to outperform the control group since improvement in vocabulary learning was found to be significant. Moreover, Qualitative results revealed the occurrence of positive changes in the learners’ attitudes about vocabulary learning since almost all the learners concurred that the above-mentioned collaborative techniques assisted them in their better speaking and, by having more interaction through group work, enjoyable environment was created for learning target vocabularies. It was suggested that collaborative instruction should be implemented in teaching vocabulary as it can pave the way for both teachers and learners to benefit from a communicative language classroom.

  8. The Role of Repeated Exposure to Multimodal Input in Incidental Acquisition of Foreign Language Vocabulary.

    Bisson, Marie-Josée; van Heuven, Walter J B; Conklin, Kathy; Tunney, Richard J

    2014-12-01

    Prior research has reported incidental vocabulary acquisition with complete beginners in a foreign language (FL), within 8 exposures to auditory and written FL word forms presented with a picture depicting their meaning. However, important questions remain about whether acquisition occurs with fewer exposures to FL words in a multimodal situation and whether there is a repeated exposure effect. Here we report a study where the number of exposures to FL words in an incidental learning phase varied between 2, 4, 6, and 8 exposures. Following the incidental learning phase, participants completed an explicit learning task where they learned to recognize written translation equivalents of auditory FL word forms, half of which had occurred in the incidental learning phase. The results showed that participants performed better on the words they had previously been exposed to, and that this incidental learning effect occurred from as little as 2 exposures to the multimodal stimuli. In addition, repeated exposure to the stimuli was found to have a larger impact on learning during the first few exposures and decrease thereafter, suggesting that the effects of repeated exposure on vocabulary acquisition are not necessarily constant.

    To describe the nature and frequency of the aided language stimulation program and determine the effects of a 3-week-long aided language stimulation program on the vocabulary acquisition skills of children with little or no functional speech (LNFS). Four children participated in this single-subject, multiple-probe study across activities. The aided language stimulation program comprised 3 activities: arts and crafts, food preparation, and story time activity. Each activity was repeated over the duration of 5 subsequent sessions. Eight target vocabulary items were taught within each activity. The acquisition of all 24 target items was probed throughout the duration of the 3-week intervention period. The frequency and nature of the aided language stimulation provided met the criterion of being used 70% of the time and providing aided language stimulation with an 80:20 ratio of statements to questions. The results indicated that all 4 participants acquired the target vocabulary items. There were, however, variations in the rate of acquisition. This study explores the impact of aided language stimulation on vocabulary acquisition in children. The most important clinical implication of this study is that a 3-week intervention program in aided language stimulation was sufficient to facilitate the comprehension of at least 24 vocabulary items in 4 children with LNFS.

    Full Text Available For almost four decades, ESL/EFL scholars have been trying to find which learning type, contextualized vs. decontextualized, leads to better vocabulary acquisition and retention. In an attempt to solve this problem, this study tried to examine the possible effectiveness of using humorous context on vocabulary acquisition and retention. Another issue that was undertaken in the present study was comparing the efficiency of contextualized and decontextualized vocabulary learning and retention. For this purpose, 58 Iranian EFL learners were categorized into 3 groups: a humorous, b non-humorous, and c decontextualized. The findings were analyzed using one-way ANOVA and Tukey post hoc test. As the results revealed, the participants in decontextualized group outperformed the participants in both humorous and non-humorous groups. However, it should be noted that the performance of humorous group was significantly better than the performance of non-humorous group.

    2015-09-01

    Full Text Available Involvement load hypothesis as a cognitive construct states that tasks with higher involvements yield better results in vocabulary retention. This comparison group designed study examined the immediate and delayed effects of tasks with different involvements in involvement load hypothesis (Laufer & Hulstijn, 2001. Applying a version of Nelson Proficiency Test as a homogenizing exclusion criterion, 33 low proficiency Iranian EFL learners were randomly assigned to three experimental groups: blank-filling, sentence making, and reading comprehension. The results of ANOVA and Kruskal-Wallis tests supported task-induced involvement in immediate posttest since the sentence making task (M=5.72 yielded better results in comparison with the other two blank-filling (M=5.45 and reading comprehension (M=3.18 tasks. Nevertheless, sentence making and blank-filling tasks of which the involvements were somehow similar did not yield significant superiority to each other. It is inferred that tasks with nearer involvements yield somehow similar results in vocabulary acquisition.

    2011-08-01

    Three studies investigated novel word learning, some requiring phonological production, each involving between 11 and 17 individuals with Down syndrome, and between 15 and 24 typically developing individuals matched for receptive vocabulary. The effect of stimuli wordlikeness and incidental procedure-based memory demands were examined to see whether these may account for an apparent impairment in word learning in Down syndrome demonstrated in earlier research. Paired associate word and nonword learning tasks were presented, requiring participants to learn the names of novel characters. The nonword stimuli varied in the degree of wordlikeness in 2 studies. A third study investigated extraneous task demand. Across 3 studies, there was no suggestion of a word learning deficit associated with Down syndrome (η(2)(p) for the main effect of group of .03, .11, and .03, respectively), despite the level of phonological representation required. There was evidence that novel word learning by participants with Down syndrome exceeded that which their verbal short-term memory capacity would predict. Vocabulary acquisition in Down syndrome may not rely on verbal short-term memory to the same extent as in typically developing children, lending support to the suggestion that new word learning may be underpinned by an additional memory process.

    Nicolay, Anne-Catherine; Poncelet, Martine

    2013-08-01

    First-language (L1) and second-language (L2) lexical development has been found to be strongly associated with phonological processing abilities such as phonological short-term memory (STM), phonological awareness, and speech perception. Lexical development also seems to be linked to attentional and executive skills such as auditory attention, flexibility, and response inhibition. The aim of this four-wave longitudinal study was to determine to what extent L2 vocabulary acquired through the particular school context of early L2 immersion education is linked to the same cognitive abilities. A total of 61 French-speaking 5-year-old kindergartners who had just been enrolled in English immersion classes were administered a battery of tasks assessing these three phonological processing abilities and three attentional/executive skills. Their English vocabulary knowledge was measured 1, 2, and 3 school years later. Multiple regression analyses showed that, among the assessed phonological processing abilities, phonological STM and speech perception, but not phonological awareness, appeared to underlie L2 vocabulary acquisition in this context of an early L2 immersion school program, at least during the first steps of acquisition. Similarly, among the assessed attentional/executive skills, auditory attention and flexibility, but not response inhibition, appeared to be involved during the first steps of L2 vocabulary acquisition in such an immersion school context.

    2004-12-01

    Full Text Available This study investigated the effects of visible and invisible links for annotated words in a computer module for learning French on the vocabulary acquisition and reading comprehension of two types of students – high – and average-achievers. Two hundred and sixty four second-semester students of French were identified as high- or average-achievers. Each type of students was then randomly assigned to two groups – with visible or invisible hyperlinks. All students were instructed to read a short passage in French (181 words for general comprehension and allowed to consult the annotated words (made visible by bold face for the visible links group as much as they needed. The students took a vocabulary pretest and an immediate and delayed (two weeks vocabulary and reading comprehension posttest. The results of the study showed that average- achievers benefited more from the visible links for vocabulary acquisition and reading comprehension than high-achievers. The results are discussed in light of second language acquisition and gifted-student theories and suggestions for future research are made.

    2015-01-01

    This study used eye tracking to investigate the allocation of attention to multimodal stimuli during an incidental learning situation, as well as its impact on subsequent explicit learning. Participants were exposed to foreign language (FL) auditory words on their own, in conjunction with written native language (NL) translations, or with both written NL translations and pictures. Incidental acquisition of FL words was assessed the following day through an explicit learning task where participants learned to recognize translation equivalents, as well as one week later through recall and translation recognition tests. Results showed higher accuracy scores in the explicit learning task for FL words presented with meaning during incidental learning, whether written meaning or both written meaning and picture, than for FL words presented auditorily only. However, participants recalled significantly more FL words after a week delay if they had been presented with a picture during incidental learning. In addition, the time spent looking at the pictures during incidental learning significantly predicted recognition and recall scores one week later. Overall, results demonstrated the impact of exposure to multimodal stimuli on subsequent explicit learning, as well as the important role that pictorial information can play in incidental vocabulary acquisition.

    Slemrod, Tal

    There is a growing recognition of the importance and effectiveness of instruction in the STEM subjects, including science. The movement towards increased requirements and expectations in science presents a challenge to both students and teachers as many students with Learning Disabilities (LD) often particularly struggle in their science classes. The purpose of this study was to investigate the use of an assistive technology (AT) intervention targeting the acquisition of science vocabulary for adolescents with LD in a general education secondary biology classroom. Participants for this study included 3 secondary students with LD who were enrolled in a biology class. An alternating treatment design was used to compare the effects of a keyword mnemonic vocabulary intervention via index cards or iPod touch on student, vocabulary acquisition, academic engagement and disruptive behavior. All students' acquired the content vocabulary equally well during both conditions. When using the AT, students' engagement increased compared to baseline conditions. It was clear that the students had a strong interest in using AT to increase their grades and engagement, however the teachers had little access and training on using AT to support their students with disabilities.

    2016-12-01

    Background Complex procedures often have numerous acceptable approaches; it is unclear how surgical fellows choose between techniques. We used pancreaticoduodenectomy as a model to catalogue variability between surgeons and investigate factors that affect fellows' acquisition of techniques. Materials and methods Semistructured interviews and operative note analysis were conducted to determine techniques of 5 attending surgeons, and these data were mapped to identify variations. Identical interviews and questioning were completed with 4 fellowship graduates whose practice includes pancreaticoduodenectomy. Results All surgeons performed a different operation, both in order and techniques employed. Based on minor variations, there were 21 surgical step data points that differed. Of 5 surgeons, 4 were unable to identify colleagues' techniques. Fellows reported adopting techniques from mentors who had regimented techniques, teaching styles they related to, and with whom they frequently operated. Residency training did not strongly influence their choice of technique; however, senior partners after fellowship did influence technique. Conclusions The number of variants of pancreaticoduodenectomy based on granular, step-by-step differences is larger than previously described. Results hint that variation may be furthered by the fact that surgeons are not aware of the techniques used by colleagues. Fellows choose techniques based on factors not directly related to their own outcomes but rather mentor factors. Whether fellows adopt techniques that will be optimal given their abilities is worthy of further investigation, as are changes in technique over time. Better codification of variation is needed to facilitate these investigations as well as matching of technical variations to patient outcomes. © The Author(s) 2016.

    Full Text Available The present study investigated the effects of selected presentation techniques including the keyword method, the peg word method, the loci method, argument mapping, concept mapping and mind mapping on L2 vocabulary comprehension and production. To this end, a sample of 151 Iranian female students from a public pre-university school in Islam Shahr was selected. They were assigned to six groups. Each group was randomly assigned to one of the afore-mentioned treatment conditions. After the experimental period, two post-tests in multiple choice and fill-in-the-blanks formats were administered to assess the participants’ vocabulary comprehension and production. Two independent One-Way ANOVA procedures were used to analyze the obtained data. The results showed that the differences among the effects of the above-mentioned techniques were statistically significant in both vocabulary comprehension and production. These findings can have implications for learners, teachers, and materials’ developers.

    Boyce, Deborah Ann

    The purpose of this study was to investigate the impact of the learning video game Quizlet on students with learning disabilities in the science classroom. Specifically this study investigated (a) student academic performance, (b) student on-task behavior, and (c) student satisfaction using the learning video game. Student academic performance was measured in terms of vocabulary acquisition, and student engagement was measured in relation to on-task behaviors. Seven middle school students, three female and four male participated in the study. A single subject design with ABABAB phases and maintenance data collection was utilized. Results show that all students increased their grades in science vocabulary and increased on-task behaviors. A follow-up student satisfaction survey determined that the intervention was acceptable to all students. Additional studies to assess the effects of Quizlet are recommended.

    2015-10-01

    The present intervention study explored the word learning of 18 children with cochlear implants in response to E-book instruction. Capitalizing on the multimedia options available in electronic storybooks, the intervention incorporated videos and definitions to provide a vocabulary intervention that includes evidence-based teaching strategies. The extent of the children's word learning was assessed using three assessment tasks: receptive pointing, expressively labeling, and word defining. Children demonstrated greater immediate expressive labeling gains and definition generation gains for words taught in the treatment condition compared to those in the comparison condition. In addition, the children's performance on delayed posttest vocabulary assessments indicated better retention across the expressive vocabulary task for words taught within the treatment condition as compared to the comparison condition. Findings suggest that children with cochlear implants with functional speech perception can benefit from an oral-only multimedia-enhanced intensive vocabulary instruction.

    Full Text Available Both cognition and affect have been proven to have a significant role in instructed second language acquisition. Unlike cognitive processes, the affective processes in language learning have not received due attention in the research on task-based language teaching. The effect of task-related emotional state on learning achievements resulting from task engagement is an almost unexplored area. The study reported here investigated the effect of emotional involvement as compared to cognitive involvement both applied to the pre-task phase of a reading-while-listening focused task on lexical acquisition as a result of engagement with the task. Emotional involvement was operationalized as a video clip shown before the main task which elicited positive affect. MANCOVA statistics indicated that both emotional and cognitive involvements had an enhancing effect on short-term retention and ease of activation of vocabulary. However, the enhancing effect was not observed for long-term acquisition. The findings imply pedagogical suggestions for task-based vocabulary teaching.

    Full Text Available In the present study, the comparative effects of comprehensible input, output and corrective feedback on the receptive acquisition of L2 vocabulary items were investigated. Two groups of beginning EFL learners participated in the study. The control group received comprehensible input only, while the experimental group received input and was required to produce written output. They also received corrective feedback on their lexical errors if any. This could result in the production of modified output. The results of the study indicated that (a the group which produced output and received feedback (if necessary outperformed the group which only received input in the post-test, (b within the experimental group, feedback played a greater role in learners’ better performance than output, (c also a positive correlation between the amount of feedback an individual learner received, and his overall performance in the post-test; and also between the amount of feedback given for a specific word and the correct responses given to its related item in the post-test was found.  The findings of this study provide evidence for the role of output production along with receiving corrective feedback in enhancing L2 processing by drawing further L2 learners’ attention to their output which in turn may result in improving their receptive acquisition of L2 words. Furthermore, as the results suggested, feedback made a more contribution to L2 development than output. Keywords: comprehensible input, output, interaction, corrective feedback, modified output, receptive vocabulary acquisition

    Full Text Available Despite a growing number of studies, the neurophysiology of adult vocabulary acquisition is still poorly understood. One reason is that paradigms that can easily be combined with neuroscientfic methods are rare. Here, we tested the efficiency of two paradigms for vocabulary (re- acquisition, and compared the learning of novel words for actions and objects. Cortical networks involved in adult native-language word processing are widespread, with differences postulated between words for objects and actions. Words and what they stand for are supposed to be grounded in perceptual and sensorimotor brain circuits depending on their meaning. If there are specific brain representations for different word categories, we hypothesized behavioural differences in the learning of action-related and object-related words. Paradigm A, with the learning of novel words for body-related actions spread out over a number of days, revealed fast learning of these new action words, and stable retention up to 4 weeks after training. The single-session Paradigm B employed objects and actions. Performance during acquisition did not differ between action-related and object-related words (time*word category: p = 0.01, but the translation rate was clearly better for object-related (79% than for action-related words (53%, p = 0.002. Both paradigms yielded robust associative learning of novel action-related words, as previously demonstrated for object-related words. Translation success differed for action- and object-related words, which may indicate different neural mechanisms. The paradigms tested here are well suited to investigate such differences with neuroscientific means. Given the stable retention and minimal requirements for conscious effort, these learning paradigms are promising for vocabulary re-learning in brain-lesioned people. In combination with neuroimaging, neuro-stimulation or pharmacological intervention, they may well advance the understanding of

    Full Text Available The present study set out to investigate the differences between EAP (English for Academic Purposes students of Humanities and Engineering in terms of vocabulary strategy choice and use. One hundred and five undergraduate Iranian students (39 students from Engineering Faculty and 66 from Humanities Faculty studying at Bu-Ali Sina University Hamedan, during the academic year of 2011–2012 participated in this study. For data collection purposes, a pilot-tested factor-analyzed five-point Likert-scale vocabulary learning strategies questionnaire (VLSQ containing 45 statements was adopted. The results of independent samples t-test indicated that, overall, the two groups were not significantly different in the choice and use of vocabulary learning strategies. However, running Chi square analyses, significant differences were found in individual strategy use in 6 out of 45 strategies. That is, while Humanities students used more superficial and straightforward strategies like repetition strategy and seeking help from others, the Engineering students preferred much deeper, thought-provoking and sophisticated strategies like using a monolingual dictionary and learning vocabulary through collocations and coordinates. Further, the most and the least frequently used vocabulary learning strategies by the two groups were specified, out of which only two strategies in each category were commonly shared by both groups. The possible reasons why the results have turned out to be so as well as the implications of the study are discussed in details in the paper.

    Full Text Available The article focuses on some possibilities of using the available materials on the inte- ractive board, which can contribute to the development of the learning strategies and to the quality as well as to the efficiency in the process of vocabulary learning. The current findings on learning strategies and vocabulary learning (Oxford 1990, Nunan 1999, Nation 2001 are combined and compared to the usage of various materials of i-board in the classroom. A meaningful usage of i-board being our priority, we found more advantages in the use of i-board in comparison to the classical exercises on the paper. Our material is based on Piepho's and Häussermann'stypology of exercises for improving vocabulary learning. The students' perception of the interactive board in classroom is included and is based on analysis of the results of an online survey of 58 students, who had been using interactive board in German language classes for two years.

    2014-01-01

    This study examined vocabulary intervention-in terms of targets and techniques-for children with language impairment receiving speech-language therapy in public schools (i.e., non-fee-paying schools) in the United States. Vocabulary treatments and targets were examined with respect to their alignment with the empirically validated practice of rich vocabulary intervention. Participants were forty-eight 5-7-year-old children participating in kindergarten or the first-grade year of school, all of whom had vocabulary-specific goals on their individualized education programmes. Two therapy sessions per child were coded to determine what vocabulary words were being directly targeted and what techniques were used for each. Study findings showed that the majority of words directly targeted during therapy were lower-level basic vocabulary words (87%) and very few (1%) were academically relevant. On average, three techniques were used per word to promote deep understanding. Interpreting findings against empirical descriptions of rich vocabulary intervention indicates that children were exposed to some but not all aspects of this empirically supported practice.

    Terry, Brian H.

    In this quasi-experimental study, the researcher investigated the effectiveness of three tactual strategies and one non-tactual strategy of content specific vocabulary acquisition. Flash cards, task cards, and learning wheels served as the tactual strategies, and vocabulary review sheets served as a non-tactual strategy. The sample (n=85) consisted of all middle school students in a small high performing middle school located in the northern suburbs of New York City. All of the vocabulary words and terms came from the New York State Intermediate Level Science Core Curriculum. Pre-tests and post-tests were used to collect the data. A repeated measures ANOVA was conducted on the gain scores from each of the treatments. Multiple paired sample t-tests were conducted to analyze the results. Repeated measures ANOVAs were used to determine if there was a variance between the academic achievement levels of the students, gender, and grade level for each of the treatments. All of the treatments significantly improved the science achievement of the students, but significance was found between them. Significance was found between the achievement groups with the above average students attaining a higher mean on the pre-test and post-test for each treatment, whereas the below average students had the lowest mean on both assessments. The sixth grade students showed significant improvement over the seventh grade students while using the flash cards (p=.004) and learning wheel (p=.007). During the learning wheel treatment, the males scored significantly better (p=.021) than the females on the pre-test and post-test. During the worksheet treatment, significance (p=.034) was found between gender and achievement group. The below average male students had the greatest gain from the pre-test to the post-test, but the post-test mean was still the lowest of the groups. Limitations, implications for future research and current practice are discussed. Key words are: flash cards, task cards

    2013-02-01

    Parents often turn to educators and healthcare professionals for advice on how to best support their child's language development. These professionals frequently suggest implementing the 'one-parent-one-language' approach to ensure consistent exposure to both languages. The goal of this study was to understand how language exposure influences the receptive vocabulary development of simultaneous bilingual children. To this end, we targeted nine German-French children growing up in bilingual families. Their exposure to each language within and outside the home was measured, as were their receptive vocabulary abilities in German and French. The results indicate that children are receiving imbalanced exposure to each language. This imbalance is leading to a slowed development of the receptive vocabulary in the minority language, while the majority language is keeping pace with monolingual peers. The one-parent-one-language approach does not appear to support the development of both of the child's languages in the context described in the present study. Bilingual families may need to consider other options for supporting the bilingual language development of their children. As professionals, we need to provide parents with advice that is based on available data and that is flexible with regards to the current and future needs of the child and his family.

    Experience can affect human gray matter volume. The behavioral correlates of individual differences in such brain changes are not well understood. In a group of Swedish individuals studying Italian as a foreign language, we investigated associations among time spent studying, acquired vocabulary, baseline performance on memory tasks, and gray matter changes. As a way of studying episodic memory training, the language learning focused on acquiring foreign vocabulary and lasted for 10weeks. T1-weighted structural magnetic resonance imaging and cognitive testing were performed before and after the studies. Learning behavior was monitored via participants' use of a smartphone application dedicated to the study of vocabulary. A whole-brain analysis showed larger changes in gray matter structure of the right hippocampus in the experimental group (N=33) compared to an active control group (N=23). A first path analyses revealed that time spent studying rather than acquired knowledge significantly predicted change in gray matter structure. However, this association was not significant when adding performance on baseline memory measures into the model, instead only the participants' performance on a short-term memory task with highly similar distractors predicted the change. This measure may tap similar individual difference factors as those involved in gray matter plasticity of the hippocampus.

    It remains unsettled whether human language relies exclusively on innately privileged brain structure in the left hemisphere or is more flexibly shaped through experiences, which induce neuroplastic changes in potentially relevant neural circuits. Here we show that learning of second language (L2) vocabulary and its cessation can induce bidirectional changes in the mirror-reverse of the traditional language areas. A cross-sectional study identified that gray matter volume in the inferior frontal gyrus pars opercularis (IFGop) and connectivity of the IFGop with the caudate nucleus and the superior temporal gyrus/supramarginal (STG/SMG), predominantly in the right hemisphere, were positively correlated with L2 vocabulary competence. We then implemented a cohort study involving 16 weeks of L2 training in university students. Brain structure before training did not predict the later gain in L2 ability. However, training intervention did increase IFGop volume and reorganization of white matter including the IFGop-caudate and IFGop-STG/SMG pathways in the right hemisphere. These "positive" plastic changes were correlated with the gain in L2 ability in the trained group but were not observed in the control group. We propose that the right hemispheric network can be reorganized into language-related areas through use-dependent plasticity in young adults, reflecting a repertoire of flexible reorganization of the neural substrates responding to linguistic experiences.

    Full Text Available Teaching vocabulary in semantically related sets use as a common practice by EFL teachers. The present study tests the effectiveness of this techniques by comparing it with semantically unrelated clusters as the other technique on Iranian intermediate EFL learners. In the study three intact classes of participants studying at Isfahan were presented with a set of unrelated words through “ 504 Absolutely Essential words”, a set of related words through “The Oxford Picture Dictionary “, and the control group were presented some new words through six texts from “Reading Through Interaction”. Comparing of the results indicated that, while both techniques help the learners to acquire new sets of the words, presenting words in semantically unrelated sets seems to be more effective.

  10. Coding Methods for the NMF Approach to Speech Recognition and Vocabulary Acquisition

    Full Text Available This paper aims at improving the accuracy of the non- negative matrix factorization approach to word learn- ing and recognition of spoken utterances. We pro- pose and compare three coding methods to alleviate quantization errors involved in the vector quantization (VQ of speech spectra: multi-codebooks, soft VQ and adaptive VQ. We evaluate on the task of spotting a vocabulary of 50 keywords in continuous speech. The error rates of multi-codebooks decreased with increas- ing number of codebooks, but the accuracy leveled off around 5 to 10 codebooks. Soft VQ and adaptive VQ made a better trade-off between the required memory and the accuracy. The best of the proposed methods reduce the error rate to 1.2% from the 1.9% obtained with a single codebook. The coding methods and the model framework may also prove useful for applica- tions such as topic discovery/detection and mining of sequential patterns.

    Subramaniam, E T

    2012-12-01

    In this paper, we discuss the design and implementation of a synchronizing technique for data acquisition systems, which can effectively use the normal, standard local area network cables to provide a time stamp, with a range up to 32 days, resolution of 10 ns, and synchronization within ± 5 ns. This system may be used to synchronize data being collected by independent heterogeneous data acquisition modules, that acquire events independently. Such distributed systems are generally designed with a tree-like structure or independent self-triggered acquisition boxes. These leaf edges are connected through branches to the root node, via non-bus based inter-connecting links. The present system has been tested with a set of self-triggered digital signal processing based data acquisition engines, having a 100 MHz analog to digital converter front end.

  12. How do verbal short-term memory and working memory relate to the acquisition of vocabulary and grammar? A comparison between first and second language learners.

    Science.gov (United States)

    Verhagen, Josje; Leseman, Paul

    2016-01-01

    Previous studies show that verbal short-term memory (VSTM) is related to vocabulary learning, whereas verbal working memory (VWM) is related to grammar learning in children learning a second language (L2) in the classroom. In this study, we investigated whether the same relationships apply to children learning an L2 in a naturalistic setting and to monolingual children. We also investigated whether relationships with verbal memory differ depending on the type of grammar skill investigated (i.e., morphology vs. syntax). Participants were 63 Turkish children who learned Dutch as an L2 and 45 Dutch monolingual children (mean age = 5 years). Children completed a series of VSTM and VWM tasks, a Dutch vocabulary task, and a Dutch grammar task. A confirmatory factor analysis showed that VSTM and VWM represented two separate latent factors in both groups. Structural equation modeling showed that VSTM, treated as a latent factor, significantly predicted vocabulary and grammar. VWM, treated as a latent factor, predicted only grammar. Both memory factors were significantly related to the acquisition of morphology and syntax. There were no differences between the two groups. These results show that (a) VSTM and VWM are differentially associated with language learning and (b) the same memory mechanisms are employed for learning vocabulary and grammar in L1 children and in L2 children who learn their L2 naturalistically.

  19. TEACHING VOCABULARY THROUGH SENTENCES

    Directory of Open Access Journals (Sweden)

    irfan tosuncuoglu

    2015-12-01

    Almost every teacher is certain about that vocabulary is an important facet of learning a second language. It may be more important than grammar, at least in so far as this concerns communication , and particularly in the early stages when learners seem to understand that amassing a basic vocabulary is very important to fluency in another language. As a rule, receptive vocabulary exceeds productive vocabulary and why listening with comprehension and speaking with comprehension are two very different things—the latter a more difficult cognitive process than the former. Furthermore, vocabulary acquisition is highly idiosyncratic and depends largely on the learner and her or his individual learning styles and cognitive abilities. No two people learn alike. In particular, as understanding and fluency increases,  individual interests and even needs will change, which then requires teacher-assisted guidance and remediation vis-à-vis the compilation of a specified and nuanced vocabulary that is tailored to the learner’s more practical linguistic needs, whatever these might be. In this case, new vocabulary items are more likely to be recalled and communicative. Essential to such an approach to teaching vocabulary acquisition, it is argued here, is exposure to authentic language, that is, reading, writing, listening, and speaking in class that both engages the visual, tactile, and aural-oral senses and imprints. In the case of texts, it is paramount that the comprehension level be such that the learner can guestimate with a nigh degree of accuracy the meaning and proper usage of new vocabulary items without a dictionary and thus from their context. And the more often these new vocabulary items appear, the more likely it is that their full meaning will be understood and committed to memory.  For that reason we wanted to make use of sentences in vocabulary teaching.

    1983-01-01

    A crops and soils data base has been developed at Purdue University's Laboratory for Applications of Remote Sensing using spectral and agronomic measurements made by several government and university researchers. The data are being used to (1) quantitatively determine the relationships of spectral and agronomic characteristics of crops and soils, (2) define future sensor systems, and (3) develop advanced data analysis techniques. Researchers follow defined data acquisition and preprocessing techniques to provide fully annotated and calibrated sets of spectral, agronomic, and meteorological data. These procedures enable the researcher to combine his data with that acquired by other researchers for remote sensing research. The key elements or requirements for developing a field research data base of spectral data that can be transported across sites and years are appropriate experiment design, accurate spectral data calibration, defined field procedures, and through experiment documentation.

    Paul, P

    1996-01-01

    With respect to reading vocabulary knowledge and deafness, this article addresses two broad questions: (1) Why is vocabulary knowledge related to reading comprehension ability? (2) How is reading vocabulary (i.e., word meanings) acquired? The article argues that the answers to these questions are best addressed by a vocabulary acquisition model labeled the knowledge model. In essence, this model asserts that both breadth and depth of vocabulary knowledge are critical. It is necessary to teach vocabulary, especially to poor readers, who are not likely to derive many word meanings from the use of context during natural or deliberate reading situations. On the basis of theoretical and research syntheses, the article offers implications for vocabulary instruction for deaf children and adolescents.

In order to analyse and evaluate these issues, we will study the lexical items presented in a specific textbook from the point of view of frequency, distribution along the manual, opportunities for rehearsal and repetition (which will depend on frequency, and the nature of the activities centred on vocabulary. The results of this case study will allow us to check whether or not they may stand a comparison against the findings of psycholinguistic and neurolinguistic research on vocabulary acquisition.

    2012-01-01

    Full Text Available When vocabulary teaching is taken into account in EFL classes in Turkish state primary schools, teachers generally prefer to use classical techniques. The purpose of this study is to find out the effect of a relatively new vocabulary teaching technique; teaching vocabulary through collocations. Pre-test/Post-test Control Group Design was employed in this study. Fifty-nine (59 seventh (7th grade students from two classrooms in a lower-middle class, suburban state primary school in Konya, Turkey participated in this study. The experimental group was taught new words using collocation technique; the control group was taught new words using classical techniques such as synonym, antonym, definition and mother tongue translation as it was in the previous reading classes before the study. The statistical analysis revealed that teaching vocabulary through collocations results in a better learning of the words than presenting them using classical techniques and enhances retention of new vocabulary items. Teaching vocabulary through collocations can be an effective factor in helping students remember and use the new words easily in primary school EFL classes. Therefore, teachers of English could be encouraged to attach more importance to vocabulary teaching rather than the acquisition of grammar and the use of current vocabulary teaching strategies in their classes.

Grammar provides the overall patterns, and vocabulary is%要学习一种语言,我们必须学习单词。英国语言学家大卫.威尔金斯说:“没有语法,人们可以表达的事物寥寥无几,而没有词汇,人们则无法表达任何事物。”语法提供的是总的句子模式,而词汇则是置于句子模式之中的语言材料。词汇习得在外语或第二语言学习中的重要性是毋庸置疑的。然而,面对数量庞大的单词,没有行之有效的方法,要完成此任务是很难的。经过一个学期(2009年9月至2010年1月)的试验表明,把记忆术用在词汇习得中,其效果比传统的方法显著得多——既提高了学习者的学习兴趣,又使单词记忆得更加准确、持久。

    Full Text Available Acquisition is a most important process and a challenge task for identifying visible satellites, coarse values of carrier frequency, and code phase of the satellite signals in designing software defined Global positioning system (GPS receiver. This paper presents a new, simple, efficient and faster GPS acquisition via sub-sampled fast Fourier transform (ssFFT. The proposed algorithm exploits the recently developed sparse FFT (or sparse IFFT that computes in sub-linear time. Further it uses the property of fourier transforms (FT: Aliasing a signal in the time domain corresponds to sub-sampling it in the frequency domain, and vice versa. The ssFFT is an FFT algorithm that computes sub-sampled version of the data by an integer factor ‘d’, and hence, the computational complexity is proportionately reduced by a factor of ‘d log d’ compared to conventional FFT-based algorithms for any length of the input GPS signal. The simulation results show that the proposed ssFFT based GPS acquisition computation is 8.5571 times faster than the conventional FFT-based acquisition computation time. The implementation of this method in an FPGA provides very fast processing of incoming GPS samples that satisfies real-time positioning requirements.Defence Science Journal, Vol. 65, No. 1, January 2015, pp.5-11, DOI:http://dx.doi.org/10.14429/dsj.65.5579

    Full Text Available Under the influence of globalization through cultural and technological exchange, English viewed as a medium of international communication enjoys its privileged status around the world. In Taiwan, English is the only foreign language tested in the entrance examinations and English is the most popular foreign language which Taiwanese people desire to master. However, many learners in Taiwan agree the fundamental and crucial role vocabulary plays in the language learning, but they think learning vocabulary is very difficult under the current method of instruction based on the use of word lists. This study aims to investigate the learning outcomes of presenting vocabulary in contexts, specifically in the contexts of literature and imaginative texts, and compare them with the use of word lists only. In the present research, two experiments were designed to investigate Taiwanese learners’ attitudes and perceptions concerning the way in which vocabulary is presented and compare their opinions about the effect of the use of word lists and literature in the foreign language classroom respectively. Questionnaires were used in both of these two experiments. The results indicated that most of the learners’ opinions agreed that the delayed presentation of words is not helpful for them in vocabulary learning as well as showed that the use of literature in the foreign language classroom is perceived as a productive and valuable resource for vocabulary learning. Implications were drawn concerning the design of textbooks used in Taiwan and also for curriculum and methodological innovation.

This article uses the pen and paper approach to examine the effects of the word forms on Chinese vocabulary acquisition of Japanese students and finds that word forms may influence the accuracy of vocabulary acquisition. Words identical in forms are acquired better than words different in forms between Japanese and Chinese. In addition, language learners' level also play a role in vocabulary mastering. The higher the learner' s level is, the better they can acquire the three types of words. We therefore suggest that in order to help Japanese students to achiever a better learning effect, we should arrange the teaching materials of vocabulary properly in the process of teaching as well as the textbook compiling according to the "transfer theory", and help the learners to take full advantage of the positive transfer and overcome negative migration.

    Full Text Available At universities in the United States, first-year Spanish instructors often wonder why their students perform below expectations in vocabulary tests. This paper addresses this question by presenting an analysis of five leading first-year college Spanish textbooks published in the United States. This analysis consists of two parts: 1 mapping the textbooks' vocabulary lists as well as the vocabulary that appears in their reading input against the vocabulary-frequency information provided in A frequency dictionary of Spanish: Core vocabulary for learners written by Mark Davies and published by Routledge in 2006, and 2 using estimations available in the current literature to infer logistical aspects that need to be considered in first-year college Spanish such as amount of contact-time with the material to be learned, depth of vocabulary knowledge, and the relationship between the receptive and productive dimensions of vocabulary acquisition. The results show that some pedagogical fine-tuning may be needed to align the amount of vocabulary presented in textbooks as well as their vocabulary selections with research findings on vocabulary acquisition and Spanish vocabulary frequency.En el ámbito de las universidades estadounidenses, a menudo los profesores de primer año de español constatan que los resultados de los exámenes de vocabulario están por debajo de sus expectativas. Este trabajo aborda esta cuestión por medio del análisis de cinco libros de texto publicados en los Estados Unidos.

  12. 3D Image Acquisition System Based on Shape from Focus Technique

    2013-04-01

    Full Text Available This paper describes the design of a 3D image acquisition system dedicated to natural complex scenes composed of randomly distributed objects with spatial discontinuities. In agronomic sciences, the 3D acquisition of natural scene is difficult due to the complex nature of the scenes. Our system is based on the Shape from Focus technique initially used in the microscopic domain. We propose to adapt this technique to the macroscopic domain and we detail the system as well as the image processing used to perform such technique. The Shape from Focus technique is a monocular and passive 3D acquisition method that resolves the occlusion problem affecting the multi-cameras systems. Indeed, this problem occurs frequently in natural complex scenes like agronomic scenes. The depth information is obtained by acting on optical parameters and mainly the depth of field. A focus measure is applied on a 2D image stack previously acquired by the system. When this focus measure is performed, we can create the depth map of the scene.

    On this NEER project the University of Florida has investigated and applied advanced communications techniques to address data acquisition and control problems within the Fuel Conditioning Facility (FCF) of Argonne National Laboratory-West (ANL-W) in Idaho Falls. The goals of this project have been to investigate and apply wireless communications techniques to solve the problem of communicating with and controlling equipment and systems within a nuclear hot cell facility with its attendant high radiation levels. Different wireless techniques, including radio frequency, infrared and power line communications were reviewed. For each technique, the challenges of radiation-hardened implementation were addressed. In addition, it has been a project goal to achieve the highest level of system reliability to ensure safe nuclear operations. Achievement of these goals would allow the eventual elimination of through-the-wall, hardwired cabling that is currently employed in the hot cell, along wit h all of the attendant problems that limit measurement mobility and flexibility.

    Simulation results of the swept-acquisition performance of residual carrier phase-locked loops (PLLs) are reported. The loops investigated are sampled data counterparts of the continuous time type II and III loops currently in use in Deep Space Network receivers. It was found that sweep rates of 0.2 B(sub L)(2) to 0.4 B(sub L)(2) Hz/s can be used, depending on the loop parameters and loop signal-to-noise ratio (SNR), where B(sub L) is the one-sided loop noise bandwidth. Type III loops are shown to be not as reliable as type II loops for acquisition using this technique, especially at low SNRs.

    Significant renal artery stenosis (RAS) is a potentially curable cause of renovascular hypertension and/or renal impairment. It is caused by either atherosclerosis or fibromuscular dysplasia. Correct and timely diagnosis remains a diagnostic challenge. MR angiography (MRA) as a minimally invasive method seems to be suitable for RAS detection, however, its diagnostic value widely differs in the literature (sensitivity 62-100% and specificity 75-100%). The aim of our prospective study was to compare the diagnostic value of contrast-enhanced MRA utilizing parallel acquisition techniques in the detection of significant RAS with digital subtraction angiography (DSA). A total of 78 hypertensive subjects with suspected renal artery stenosis were examined on a 1.5 Tesla MR system using a body array coil. Bolus tracking was used to monitor the arrival of contrast agent to the abdominal aorta. The MRA sequence parameters were as follows: TR 3.7 ms; TE 1.2 ms; flip angle 25{sup o}; acquisition time 18 s; voxel size 1.1 mm x 1.0 mm x 1.1 mm; centric k-space sampling; parallel acquisition technique with acceleration factor of 2 (GRAPPA). Renal artery stenosis of 60% and more was considered hemodynamically significant. The results of MRA were compared to digital subtraction angiography serving as a standard of reference. Sensitivity and specificity of MRA in the detection of hemodynamically significant renal artery stenosis were 90% and 96%, respectively. Prevalence of RAS was 39% in our study population. Contrast-enhanced MRA with high spatial resolution offers sufficient sensitivity and specificity for screening of RAS.

    Diffusion MRI (dMRI) is a popular noninvasive imaging modality for the investigation of the neonate brain. It enables the assessment of white matter integrity, and is particularly suited for studying white matter maturation in the preterm and term neonate brain. Diffusion tractography allows the delineation of white matter pathways and assessment of connectivity in vivo. In this review, we address the challenges of performing and analysing neonate dMRI. Of particular importance in dMRI analysis is adequate data preprocessing to reduce image distortions inherent to the acquisition technique, as well as artefacts caused by head movement. We present a summary of techniques that should be used in the preprocessing of neonate dMRI data, and demonstrate the effect of these important correction steps. Furthermore, we give an overview of available analysis techniques, ranging from voxel-based analysis of anisotropy metrics including tract-based spatial statistics (TBSS) to recently developed methods of statistical analysis addressing issues of resolving complex white matter architecture. We highlight the importance of resolving crossing fibres for tractography and outline several tractography-based techniques, including connectivity-based segmentation, the connectome and tractography mapping. These techniques provide powerful tools for the investigation of brain development and maturation. (orig.)

    Full Text Available Adults attending short, language for specific purpose courses may have expertise not utilized in general foreign language courses. The present study investigates two factors that may influence the acquisition of medical Spanish vocabulary in such persons: native English vocabulary size and topic knowledge. Forty-four health care workers attended 12 hr of medical Spanish instruction. Prior to instruction, the Nelson–Denny Vocabulary Test, a Medical Spanish vocabulary test, and an English Medical Terminology Test (an indicator of topic knowledge were administered. The Medical Spanish Vocabulary Test was readministered at posttest. Individually, both English medical terminology knowledge and English vocabulary size were significant predictors of medical Spanish vocabulary acquisition, but English medical terminology knowledge explained most of the variance in medical Spanish vocabulary acquisition. The results are discussed in terms of the impact of expert memory organization on the ability to learn new labels in a second language. A curricular shift toward content-centered vocabulary in language for specific purpose courses may be advantageous for some groups of foreign language learners.

    Full Text Available The present study aimed to investigate the effects of implementing two innovative speaking tasks, namely, information-loaded and negotiation-oriented tasks, on the incidental vocabulary acquisition of advanced Iranian EFL learners. To this end, an experimental research was conducted in an English language institute with 30 homogeneous advanced EFL learners randomly divided into two experimental groups. Experimental group I performed some information-loaded tasks using thirty five texts as speaking aids for implementing multicultural experiences, and experimental group II performed some negotiation-oriented tasks utilizing seven argumentative sentences for each topic to promote divergent thinking processes. At the end of the treatment, a vocabulary post-test and a questionnaire were administered to measure the effects of the treatments on the students’ incidental vocabulary knowledge and attitude to the performed tasks in each group. The statistical analysis of the data revealed that the information-loaded tasks group had significantly outperformed the negotiation-oriented tasks group on the vocabulary post-test and had a significantly more positive attitude to the tasks they performed in their class. This study offers some implications for the development of a sizable and profound knowledge of vocabulary in an effortless and pleasant manner. It also fulfils the need of EFL teachers and material developers in their search for some effective activities and techniques that can help to improve EFL learners’ incidental vocabulary knowledge.

This study describes young DLL children's (N = 177) vocabulary development in both English and Spanish simultaneously, and how vocabulary skills in each language relate to one another, during a contextual shift that places greater emphasis on the acquisition of academic English language skills. Findings demonstrated that DLL preschoolers made gains in vocabulary in both languages with more change evidenced in receptive, in comparison to expressive, vocabulary as well as in English in comparison to Spanish. When examining whether children's vocabulary scores in one language at the beginning of preschool interact with their vocabulary scores in the other language to predict vocabulary growth, no significant associations were found for receptive vocabulary. In contrast, the interaction between initial English and Spanish expressive vocabulary scores was negatively related to growth in English expressive vocabulary. This cross-language association suggests that children who have low expressive vocabulary skills in both languages tend to grow faster in their English expressive vocabulary. The study extends previous work on dual language development by examining growth in expressive and receptive vocabulary in both English and Spanish. It also provides suggestions for future work to inform a more comprehensive understanding of DLL children's development in both languages.

    adjectives remained below 10% in the vocabularies of 1-400 words. There was a significant main effect of time, gender, maternal education and residual hearing with hearing aids before implantation on early receptive vocabulary growth. Time and residual hearing with hearing aids had a significant main effect also on expressive vocabulary growth. Vocabulary development of children with bilateral CIs may be delayed. Thus, early vocabulary development needs to be assessed carefully in order to provide children and families with timely and targeted early intervention for vocabulary acquisition. © 2017 Royal College of Speech and Language Therapists.

    2013-04-01

    In this study, the authors evaluated the efficacy of a Spanish-English versus English-only vocabulary intervention for dual-language learners (DLLs) with language impairment compared to mathematics intervention groups and typically developing controls with no intervention. Further, in this study the authors also examined whether the language of instruction affected English, Spanish, and conceptual vocabulary differentially. The authors randomly assigned 202 preschool DLLs with language impairment to 1 of 4 conditions: bilingual vocabulary, English-only vocabulary, bilingual mathematics, or English-only mathematics. Fifty-four DLLs with typical development received no intervention. The vocabulary intervention consisted of a 12-week small-group dialogic reading and hands-on vocabulary instruction of 45 words. Postintervention group differences and linear growth rates were examined in conceptual, English, and Spanish receptive and expressive vocabulary for the 45 treatment words. Results indicate that the bilingual vocabulary intervention facilitated receptive and expressive Spanish and conceptual vocabulary gains in DLLs with language impairment compared with the English vocabulary intervention, mathematics intervention, and no-intervention groups. The English-only vocabulary intervention differed significantly from the mathematics condition and no-intervention groups on all measures but did not differ from the bilingual vocabulary intervention. Vocabulary growth rates postintervention slowed considerably. Results support the idea that bilingual interventions support native- and second-language vocabulary development. English-only intervention supports only English. Use of repeated dialogic reading and hands-on activities facilitates vocabulary acquisition.

    Grammar provides the overall patterns, and vocabulary is the material to put in the patterns. Without grammar we can convey a little, but without vocabulary we can convey nothing. Vocabulary teaching is an indispensable part of English curriculum. Art is a kind of creation. Teaching vocabulary artistically can make teachers and students build up created consciousness in teaching and learning vocabulary activities and teachers put their experience and emotions towards beauty into teaching activities to raise general vocabulary teaching activities to appreciation of beauty and creative activities, convert bitter into happy, tense into ease. Thus the non-intellectual factors like motive, interest, emotion, self-confidence and so on can be developed naturally and they will elaborate a great part in English vocabulary teaching. At the same time, the relationship between teachers and students can get improved fundamentally furthest and it pushes vocabulary teaching powerfully in turn.

  16. Effects of various event building techniques on data acquisition system architectures

    Energy Technology Data Exchange (ETDEWEB)

    Barsotti, E.; Booth, A.; Bowden, M.

    1990-04-01

    The preliminary specifications for various new detectors throughout the world including those at the Superconducting Super Collider (SSC) already make it clear that existing event building techniques will be inadequate for the high trigger and data rates anticipated for these detectors. In the world of high-energy physics many approaches have been taken to solving the problem of reading out data from a whole detector and presenting a complete event to the physicist, while simultaneously keeping deadtime to a minimum. This paper includes a review of multiprocessor and telecommunications interconnection networks and how these networks relate to event building in general, illustrating advantages of the various approaches. It presents a more detailed study of recent research into new event building techniques which incorporate much greater parallelism to better accommodate high data rates. The future in areas such as front-end electronics architectures, high speed data links, event building and online processor arrays is also examined. Finally, details of a scalable parallel data acquisition system architecture being developed at Fermilab are given. 35 refs., 31 figs., 1 tab.

    Terrain instability, landslides and other phenomena mostly caused by hydrogeological risk, often cause damages to human infrastructures, roads and other transport lines: given the recent developments in surveying, electronics and mobile instrumentation, the quest for automated or semi-automated early warning systems is continuously increasing in order to provide reliable technological solutions to reduce risks for both human lives and human building and infrastructures. This work deals with the monitoring a specific area of interest, a landslide located in Cancia (Belluno, Italy). This case study is characterized by the presence of several roads close to the landslide area: in particular, one of them intersects with the landslide. The closeness between landslide and human used areas (e.g. roads) motivate the interest of public authorities in order to reduce risks related to the landslide. To this aim, "Provincia di Belluno, Servizio Difesa del Suolo" actively contributed to this work by providing aerial imagery data of the region of interest. Accessing a reliable reconstruction of certain landslides can be complex due to the difficulty for humans to reach certain areas: often only part of the area of interest can be acquired with highly accurate ground surveying (e.g. terrestrial laser scanning (TLS)), whereas other methods should be considered in order to obtain estimates of the remaining parts of the landslide. Recently, the spread of low cost drones is leading to a growing interest in the choice of unmanned aerial vehicles (UAVs) to acquire aerial imagery, hence enabling low cost photogrammetric reconstruction of the area. Despite being an attractive solution because of the clear convenience in terms of cost and acquisition time, its accuracy has typically not reached that of TLS surveying so far. This paper considers the possibility of comparing and integrating different acquisition techniques (TLS, aerial and close-range photogrammetry) in order to reach the

  13. Application of Chang's attenuation correction technique for single-photon emission computed tomography partial angle acquisition of Jaszczak phantom

    Directory of Open Access Journals (Sweden)

    Krishnendu Saha

    2016-01-01

    Full Text Available The acquisition and processing of the Jaszczak phantom is a recommended test by the American College of Radiology for evaluation of gamma camera system performance. To produce the reconstructed phantom image for quality evaluation, attenuation correction is applied. The attenuation of counts originating from the center of the phantom is greater than that originating from the periphery of the phantom causing an artifactual appearance of inhomogeneity in the reconstructed image and complicating phantom evaluation. Chang's mathematical formulation is a common method of attenuation correction applied on most gamma cameras that do not require an external transmission source such as computed tomography, radionuclide sources installed within the gantry of the camera or a flood source. Tomographic acquisition can be obtained in two different acquisition modes for dual-detector gamma camera; one where the two detectors are at 180° configuration and acquire projection images for a full 360°, and the other where the two detectors are positioned at a 90° configuration and acquire projections for only 180°. Though Chang's attenuation correction method has been used for 360° angle acquisition, its applicability for 180° angle acquisition remains a question with one vendor's camera software producing artifacts in the images. This work investigates whether Chang's attenuation correction technique can be applied to both acquisition modes by the development of a Chang's formulation-based algorithm that is applicable to both modes. Assessment of attenuation correction performance by phantom uniformity analysis illustrates improved uniformity with the proposed algorithm (22.6% compared to the camera software (57.6%.

  14. Development and application of a high speed digital data acquisition technique to study steam bubble collapse using particle image velocimetry

    Energy Technology Data Exchange (ETDEWEB)

    Schmidl, W.D.

    1992-08-01

    The use of a Particle Image Velocimetry (PIV) method, which uses digital cameras for data acquisition, for studying high speed fluid flows is usually limited by the digital camera's frame acquisition rate. The velocity of the fluid under study has to be limited to insure that the tracer seeds suspended in the fluid remain in the camera's focal plane for at least two consecutive images. However, the use of digital cameras for data acquisition is desirable to simplify and expedite the data analysis process. A technique was developed which will measure fluid velocities with PIV techniques using two successive digital images and two different framing rates simultaneously. The first part of the method will measure changes which occur to the flow field at the relatively slow framing rate of 53.8 ms. The second part will measure changes to the same flow field at the relatively fast framing rate of 100 to 320 [mu]s. The effectiveness of this technique was tested by studying the collapse of steam bubbles in a subcooled tank of water, a relatively high speed phenomena. The tracer particles were recorded and velocity vectors for the fluid were obtained far from the steam bubble collapse.

  16. Combined acquisition technique (CAT for neuroimaging of multiple sclerosis at low specific absorption rates (SAR.

    Directory of Open Access Journals (Sweden)

    Armin Biller

    Full Text Available PURPOSE: To compare a novel combined acquisition technique (CAT of turbo-spin-echo (TSE and echo-planar-imaging (EPI with conventional TSE. CAT reduces the electromagnetic energy load transmitted for spin excitation. This radiofrequency (RF burden is limited by the specific absorption rate (SAR for patient safety. SAR limits restrict high-field MRI applications, in particular. MATERIAL AND METHODS: The study was approved by the local Medical Ethics Committee. Written informed consent was obtained from all participants. T2- and PD-weighted brain images of n = 40 Multiple Sclerosis (MS patients were acquired by CAT and TSE at 3 Tesla. Lesions were recorded by two blinded, board-certificated neuroradiologists. Diagnostic equivalence of CAT and TSE to detect MS lesions was evaluated along with their SAR, sound pressure level (SPL and sensations of acoustic noise, heating, vibration and peripheral nerve stimulation. RESULTS: Every MS lesion revealed on TSE was detected by CAT according to both raters (Cohen's kappa of within-rater/across-CAT/TSE lesion detection κCAT = 1.00, at an inter-rater lesion detection agreement of κLES = 0.82. CAT reduced the SAR burden significantly compared to TSE (p<0.001. Mean SAR differences between TSE and CAT were 29.0 (± 5.7 % for the T2-contrast and 32.7 (± 21.9 % for the PD-contrast (expressed as percentages of the effective SAR limit of 3.2 W/kg for head examinations. Average SPL of CAT was no louder than during TSE. Sensations of CAT- vs. TSE-induced heating, noise and scanning vibrations did not differ. CONCLUSION: T2-/PD-CAT is diagnostically equivalent to TSE for MS lesion detection yet substantially reduces the RF exposure. Such SAR reduction facilitates high-field MRI applications at 3 Tesla or above and corresponding protocol standardizations but CAT can also be used to scan faster, at higher resolution or with more slices. According to our data, CAT is no more uncomfortable than TSE scanning.

    There are multiple vocabularies and thesauri within astronomy, of which the best known are the 1993 IAU Thesaurus and the keyword list maintained by A&A, ApJ and MNRAS. The IVOA has agreed on a standard for publishing vocabularies, based on the W3C skos standard, to allow greater automated interaction with them, in particular on the Web. This allows links with the Semantic Web and looks forward to richer applications using the technologies of that domain. Vocabulary-aware applications can benefit from improvements in both precision and recall when searching for bibliographic or science data, and lightweight intelligent filtering for services such as VOEvent streams. In this paper we present two applications, the Vocabulary Explorer and its companion the Mapping Editor, which have been developed to support the use of vocabularies in the Virtual Observatory. These combine Semantic Web and Information Retrieval technologies to illustrate the way in which formal vocabularies might be used in a practical application, provide an online service which will allow astronomers to explore and relate existing vocabularies, and provide a service which translates free text user queries into vocabulary terms.

    Attaining paediatric brain images of diagnostic quality can be difficult because of young age or neurological impairment. The use of anaesthesia to reduce movement in MRI increases clinical risk and cost, while CT, though faster, exposes children to potentially harmful ionising radiation. MRI acquisition techniques that aim to decrease movement artefact may allow diagnostic paediatric brain imaging without sedation or anaesthesia. We conducted a systematic review to establish the evidence base for ultra-fast sequences and sequences using oversampling of k-space in paediatric brain MR imaging. Techniques were assessed for imaging time, occurrence of movement artefact, the need for sedation, and either image quality or diagnostic accuracy. We identified 24 relevant studies. We found that ultra-fast techniques had shorter imaging acquisition times compared to standard MRI. Techniques using oversampling of k-space required equal or longer imaging times than standard MRI. Both ultra-fast sequences and those using oversampling of k-space reduced movement artefact compared with standard MRI in unsedated children. Assessment of overall diagnostic accuracy was difficult because of the heterogeneous patient populations, imaging indications, and reporting methods of the studies. In children with shunt-treated hydrocephalus there is evidence that ultra-fast MRI is sufficient for the assessment of ventricular size. (orig.)

    . However, the application of LADIES is limited for its knowledge bases. And it is difficult to use in other fields because the knowledge bases are setup manually. So we investigate the techniques of automatic knowledge acquisition in order to solve the above problems to some extent. In the second part, we introduce the basic ideas of AKA and some Machine Learning (ML) methods which AKA applies. Then we propose a comprehensive dictionary model that contains grammar, semantic and pragmatic information of words. And we investigate a strategy of automatic learning pragmatic information for words. Also we put forward another strategy of automatic learning rule of salience sentences in texts and based on it, we establish an AA system LADIES-NEW. Eventually, we suggest a AKA-based AA system model called hierarchical feature extracting AA system model.

    Full Text Available This study investigated whether it is possible to provide naturalistic second language acquisition (SLA of vocabulary for young learners in a classroom situation without resorting to a classical immersion approach. Participants were 60 first-grade pupils in Norwegian two elementary schools in their first year. The control group followed regular instruction as prescribed by the school curriculum, while the experimental group received increased naturalistic target language input. This entailed extensive use of English by the teacher during English classes, and also during morning meetings and for simple instructions and classroom management throughout the day. Our hypothesis was that it is possible to facilitate naturalistic acquisition through better quality target language exposure within a normal curriculum. The students' English vocabulary knowledge was measured using the Peabody Picture Vocabulary Test, version 4 (PPVT-IV, Dunn & Dunn, 2007, at the beginning and the end of the first year of school. Findings are that 1 early-start second-language (L2 programs in school do not in themselves guarantee vocabulary development in the first year, 2 a focus on increased exposure to the L2 can lead to a significant increase in receptive vocabulary comprehension in the course of only eight months, and 3 even with relatively modest input, learners in such an early-start L2 program can display vocabulary acquisition comparable in some respects to that of younger native children matched on vocabulary size. The overall conclusion is that naturalistic vocabulary acquisition is in fact possible in a classroom setting.

    2015-03-01

    Low frequency 1/f noise is one of the key limiting factors of high precision measurement instruments. In this paper, digital correlated double sampling is implemented to reduce the offset and low frequency 1/f noise of a data acquisition system with 24-bit sigma delta (Σ-Δ) analog to digital converter (ADC). The input voltage is modulated by cross-coupled switches, which are synchronized to the sampling clock, and converted into digital signal by ADC. By using a proper switch frequency, the unwanted parasitic signal frequencies generated by the switches are avoided. The noise elimination processing is made through the principle of digital correlated double sampling, which is equivalent to a time shifted subtraction for the sampled voltage. The low frequency 1/f noise spectrum density of the data acquisition system is reduced to be flat down to the measurement frequency lower limit, which is about 0.0001 Hz in this paper. The noise spectrum density is eliminated by more than 60 dB at 0.0001 Hz, with a residual noise floor of (9 ± 2) nV/Hz1/2 which is limited by the intrinsic white noise floor of the ADC above its corner frequency.

    2017-05-01

    While selected/multiple-reaction monitoring (SRM or MRM) is considered the gold standard for quantitative protein measurement, emerging data-independent acquisition (DIA) using high-resolution scans have opened a new dimension of high-throughput, comprehensive quantitative proteomics. These newer methodologies are particularly well suited for discovery of biomarker candidates from human disease samples, and for investigating and understanding human disease pathways. Areas covered: This article reviews the current state of targeted and untargeted DIA mass spectrometry-based proteomic workflows, including SRM, parallel-reaction monitoring (PRM) and untargeted DIA (e.g., SWATH). Corresponding bioinformatics strategies, as well as application in biological and clinical studies are presented. Expert commentary: Nascent application of highly-multiplexed untargeted DIA, such as SWATH, for accurate protein quantification from clinically relevant and disease-related samples shows great potential to comprehensively investigate biomarker candidates and understand disease.

    Full Text Available The aim of this work was to propose a methodology supporting the task of collecting the comparative data on studies of the mechanical properties of ADI. Collecting of research data is an important step in the process of finding the optimum design solutions for newly made products - experimental data allow us properly calibrate the manufacturing process of ADI to let the final product achieve the required properties. Parameters of the ADI production process, i.e. the time and temperature of austenitising and austempering, as well as the alloying elements added to ductile iron affect the ADI properties. The design process can use research data collected, among others, from the Web. As stated in the article, the process of data acquisition can be supported by semantic technologies, including ontologies which are descriptive logic formalism.

  12. A novel anthropomorphic flow phantom for the quantitative evaluation of prostate DCE-MRI acquisition techniques

    Knight, Silvin P.; Browne, Jacinta E.; Meaney, James F.; Smith, David S.; Fagan, Andrew J.

    2016-10-01

    A novel anthropomorphic flow phantom device has been developed, which can be used for quantitatively assessing the ability of magnetic resonance imaging (MRI) scanners to accurately measure signal/concentration time-intensity curves (CTCs) associated with dynamic contrast-enhanced (DCE) MRI. Modelling of the complex pharmacokinetics of contrast agents as they perfuse through the tumour capillary network has shown great promise for cancer diagnosis and therapy monitoring. However, clinical adoption has been hindered by methodological problems, resulting in a lack of consensus regarding the most appropriate acquisition and modelling methodology to use and a consequent wide discrepancy in published data. A heretofore overlooked source of such discrepancy may arise from measurement errors of tumour CTCs deriving from the imaging pulse sequence itself, while the effects on the fidelity of CTC measurement of using rapidly-accelerated sequences such as parallel imaging and compressed sensing remain unknown. The present work aimed to investigate these features by developing a test device in which ‘ground truth’ CTCs were generated and presented to the MRI scanner for measurement, thereby allowing for an assessment of the DCE-MRI protocol to accurately measure this curve shape. The device comprised a four-pump flow system wherein CTCs derived from prior patient prostate data were produced in measurement chambers placed within the imaged volume. The ground truth was determined as the mean of repeat measurements using an MRI-independent, custom-built optical imaging system. In DCE-MRI experiments, significant discrepancies between the ground truth and measured CTCs were found for both tumorous and healthy tissue-mimicking curve shapes. Pharmacokinetic modelling revealed errors in measured K trans, v e and k ep values of up to 42%, 31%, and 50% respectively, following a simple variation of the parallel imaging factor and number of signal averages in the acquisition

    2017-11-01

    Vocabulary is a key component of language that can impact on children's future literacy and communication. The gap between Australian Aboriginal and non-Aboriginal children's reading and academic outcomes is well reported and similar to Indigenous/non-Indigenous gaps in other nations. Determining factors that influence vocabulary acquisition over time and may be responsive to treatment is important for improving Aboriginal children's communication and academic outcomes. To determine what factors influence Australian urban Aboriginal children's receptive vocabulary acquisition and whether any of these are risks or protective for vocabulary development. One hundred thirteen Aboriginal children in South Western Sydney from the longitudinal birth cohort Gudaga study were assessed on The Peabody Picture Vocabulary Test multiple times: 3 years, just prior to school entry, at the end of the first and second years of formal schooling. Multilevel models were used to determine the effects of 13 fixed and manipulable maternal, child, and family variables drawn from previous research. Higher maternal education was found to be protective at 3 years and over time. The number of children in urban Australian Aboriginal households made an impact on vocabulary development and this varied over time. From 3 to 6 years, those with early poor non-verbal cognitive skills had vocabulary skills that remained below those with stronger non-verbal skills at 3 years. Girls exhibit an earlier advantage in vocabulary acquisition, but this difference is not sustained after 4 years of age. The risk and protective factors for vocabulary development in Australian Aboriginal children are similar to those identified in other studies with some variation related to the number of children in the home. In this limited set of predictors, maternal education, gender, non-verbal cognitive skills, and the number of children in households were all shown to impact on the acquisition of vocabulary to 3

MÉTODO: os participantes foram divididos em grupos de controle (GC e estudo (GE e apresentavam idades entre cinco e sete anos. Foram aplicados os testes de vocabulário expressivo e consciência fonológica, e foi realizada análise estatística dos dados. RESULTADOS: as crianças do GE, de uma maneira geral, atingiram um desempenho inferior aos participantes do GC nas tarefas analisadas. As crianças do GE de cinco e do GE de sete anos apresentaram alguns resultados significativamente inferiores ao GC; porém não houve diferenças entre os grupos de seis anos. Ao comparar o desempenho das crianças com os valores de referência, as crianças de cinco anos, de ambos os grupos, apresentaram dificuldades nas mesmas tarefas, de vocabulário expressivo e consciência fonológica, com variações de complexidade. Os sujeitos de seis e sete anos mostraram dificuldades apenas em vocabulário expressivo. CONCLUSÃO: as crianças com desvio fonológico apresentaram um desempenho inferior em algumas habilidades de vocabulário e consciência fonológica quando comparadas às crianças com desenvolvimento típico. Pode-se concluir ainda que existe influência da idade no desempenho destas habilidades para ambos os grupos, pois, com o aumento da idade, os participantes apresentaram dificuldades apenas em vocabulário e não mais em consciência fonológica.PURPOSE: to compare the performance of children with phonological disorder and with typical language acquisition through tests of expressive vocabulary and phonological awareness, and to evaluate the age influence.

    2017-08-16

    We examined the effects of vocabulary, lexical characteristics (age of acquisition and phonotactic probability), and auditory access (aided audibility and daily hearing aid [HA] use) on speech perception skills in children with HAs. Participants included 24 children with HAs and 25 children with normal hearing (NH), ages 5-12 years. Groups were matched on age, expressive and receptive vocabulary, articulation, and nonverbal working memory. Participants repeated monosyllabic words and nonwords in noise. Stimuli varied on age of acquisition, lexical frequency, and phonotactic probability. Performance in each condition was measured by the signal-to-noise ratio at which the child could accurately repeat 50% of the stimuli. Children from both groups with larger vocabularies showed better performance than children with smaller vocabularies on nonwords and late-acquired words but not early-acquired words. Overall, children with HAs showed poorer performance than children with NH. Auditory access was not associated with speech perception for the children with HAs. Children with HAs show deficits in sensitivity to phonological structure but appear to take advantage of vocabulary skills to support speech perception in the same way as children with NH. Further investigation is needed to understand the causes of the gap that exists between the overall speech perception abilities of children with HAs and children with NH.

    We all focus on the students' abilities of listening, speaking, wading, writing and translating in college teaching. But actually, it is nothing without vocabulary. Thus, vocabulary teaching is an essential part in English teaching. However, seme traditional teaching takes vocabuhury out from the context, which costs a lot of time and energy, but students are involved in the dull circle of memorizing to forgetting to memorizing again. Finally, they lose their patience on English learning and maybe give it up. In this paper, we discuss some vocabulary teaching strategies, so as to help the memorizing of vocabulary and enhance the efficiency of vocabulary teaching and learning.

  3. Vocabulary Breadth and Field Dependence/Independence Cognitive Styles

    2011-07-01

    Full Text Available This article is primarily bidirectional in that it is concerned with two fields of cognitive styles of field-dependency/independency on one hand and breadth of vocabulary knowledge on the other hand. In other word, this research is primarily intended to investigate the nature of the students' vocabulary knowledge in the field of passive and active knowledge of L2 words as a whole with regard to their preferred cognitive style of field dependency/independency. A group of 60 undergraduate students majoring in the field of English Language Teaching was selected. They were then divided into two groups based on the basis of their preferred cognitive styles of field-dependency / independency. Four types of tests, the 1000 frequency word-level test, the passive version of vocabulary Levels Test, the Productive Version of the Vocabulary Levels Test, and the Group Imbedded Figures Test were administered to the participants. The conclusion drawn after the analysis of the data was that the fieldindependent group outperformed their field-dependent counterparts in dealing with both passive and productive vocabulary levels. Finally, the findings of this research could be interpreted as being supportive of the idea that the field-dependent/independent cognitive style could be considered as an effective factor influencing the learners' vocabulary learning in the field of second language acquisition.

    Full Text Available The present study attempted to investigate the role of using word games in L2 vocabulary acquisition. 12 female participants from Uludag University were selected for control and experimental groups. Additionally, 35 participants from different universities in Turkey were invited to attend the study. First, an online questionnaire about the effect of games on vocabulary learning was administered to 35 participants. And results were analysed.  Secondly, 12 female participants were divided into two groups as control group and experimental group. Both groups were taught certain words, however, a word game known as “Bingo” were utilized for the experimental group. Finally, a vocabulary quiz was administered to both groups to determine the differences between them. The scores obtained from vocabulary quiz showed that the experimental group outperformed the control group in vocabulary quiz. Even so, there was not a significant difference between the results of the quiz. Similarly, the findings of the questionnaire indicated that the participants preferred learning through vocabulary games rather than traditional way. Also, the findings revealed that games reduce negative feelings during the learning process. It was suggested that teachers should reconsider the role of games and appreciate their educational value.

    2011-04-01

    Conventional 2D radial projections suffer from losses in signal-to-noise ratio efficiency because of the nonuniform k-space sampling. In this study, a 2D projection reconstruction method with variable gradient amplitudes is presented to cover the k-space uniformly. The gradient is designed to keep the average sampling density constant. By this, signal-to-noise ratio is increased, and the linear form of the radial trajectory is kept. The simple gradient design and low hardware requirements in respect of slew rate allow an easy implementation at MR scanners. Measurements with the density-adapted 2D radial trajectory were compared with the conventional projection reconstruction method. It is demonstrated that the density-adapted 2D radial trajectory technique provides higher signal-to-noise ratio (up to 28% in brain tissue), less blurring, and fewer artifacts in the presence of magnetic field inhomogeneities than imaging with the conventional 2D radial trajectory scheme. The presented sequence is well-suited for electrocardiographically gated sodium heart MRI and other applications with short relaxation times. Copyright © 2010 Wiley-Liss, Inc.

  8. Technique for real-time frontal face image acquisition using stereo system

    2013-04-01

    Most part of existing systems for face recognition is usually based on two-dimensional images. And the quality of recognition is rather high for frontal images of face. But for other kind of images the quality decreases significantly. It is necessary to compensate for the effect of a change in the posture of a person (the camera angle) for correct operation of such systems. There are methods of transformation of 2D image of the person to the canonical orientation. The efficiency of these methods depends on the accuracy of determination of specific anthropometric points. Problems can arise for cases of partly occlusion of the person`s face. Another approach is to have a set of person images for different view angles for the further processing. But a need for storing and processing a large number of two-dimensional images makes this method considerably time-consuming. The proposed technique uses stereo system for fast generation of person face 3D model and obtaining face image in given orientation using this 3D model. Real-time performance is provided by implementing and graph cut methods for face surface 3D reconstruction and applying CUDA software library for parallel calculation.

    Full Text Available This study compared the effectiveness of three techniques for teaching English vocabulary to Persian native speakers: a traditional procedure, the classical cloze procedure, and an innovative procedure, which is dubbed here as vicinity technique, based on incidental learning, noticing and consciousness-raising. To do the comparison, 51 students, registered at a private language institute, were randomly assigned to three groups and were taught 40 vocabulary items in five sessions in the three procedures. To evaluate the vocabulary gain in the three conditions, immediate and delayed post-tests were administered and the obtained data were analyzed using ANOVA. The results revealed that the vicinity technique was more effective than the traditional procedure; both in immediate and delayed evaluations. It was also revealed that, although there was no significant difference between the vicinity technique and the classical cloze technique in short-term, the vicinity technique was more effective than the classical cloze one for long-term retention.

The results showed that completing the tasks collabora⁃tively led to a significantly greater accuracy of task completion than completing them individually. However collaborative tasks did not lead to significantly greater gains of vocabulary knowledge than individual tasks. Interestingly a significant interaction effect was found between task type and task condition with the collaborative editing tasks being significantly more effective in promoting the gains of vocabulary knowledge.

  12. The pace of vocabulary growth helps predict later vocabulary skill.

    2012-01-01

    Children vary widely in the rate at which they acquire words--some start slow and speed up, others start fast and continue at a steady pace. Do early developmental variations of this sort help predict vocabulary skill just prior to kindergarten entry? This longitudinal study starts by examining important predictors (socioeconomic status [SES], parent input, child gesture) of vocabulary growth between 14 and 46 months (n = 62) and then uses growth estimates to predict children's vocabulary at 54 months. Velocity and acceleration in vocabulary development at 30 months predicted later vocabulary, particularly for children from low-SES backgrounds. Understanding the pace of early vocabulary growth thus improves our ability to predict school readiness and may help identify children at risk for starting behind.

    To extend the parameter restrictions of a silent echo-planar imaging (sEPI) sequence using sinusoidal readout (RO) gradients, in particular with increased spatial resolution. The sound pressure level (SPL) of the most feasible configurations is compared to conventional EPI having trapezoidal RO gradients. We enhanced the sEPI sequence by integrating a parallel acquisition technique (PAT) on a 3 T magnetic resonance imaging (MRI) system. The SPL was measured for matrix sizes of 64 × 64 and 128 × 128 pixels, without and with PAT (R = 2). The signal-to-noise ratio (SNR) was examined for both sinusoidal and trapezoidal RO gradients. Compared to EPI PAT, the SPL could be reduced by up to 11.1 dB and 5.1 dB for matrix sizes of 64 × 64 and 128 × 128 pixels, respectively. The SNR of sinusoidal RO gradients is lower by a factor of 0.96 on average compared to trapezoidal RO gradients. The sEPI PAT sequence allows for 1) increased resolution, 2) expanded RO frequency range toward lower frequencies, which is in general beneficial for SPL, or 3) shortened TE, TR, and RO train length. At the same time, it generates lower SPL compared to conventional EPI for a wide range of RO frequencies while having the same imaging parameters. Copyright © 2012 Wiley Periodicals, Inc.

    Full Text Available In this paper we have looked at the difference between teaching language structure and teaching vocabulary. We have discussed how counts of frequency alone are not enough to determine what words should be taught. We have seen that knowing a word means more than just knowing its meaning. Even that is problematical since meaning includes sense relations and context, for example. To know a word we also need to know about its use, how it is formed and what grammatical behavior it provokes. Above all, in this paper, we have approached the idea of how vocabulary teaching and learning need to be emphasized in order for students to be competent language users.

    Recognizing familiar words quickly and accurately facilitates learning new words, as well as other aspects of language acquisition. This study used the visual world paradigm with semantic and phonological competitors to study lexical processing efficiency in 2-5 year-old children. Experiment 1 found this paradigm was sensitive to vocabulary-size differences. Experiment 2 included a more diverse group of children who were tested in their native dialect (either African American English or Mainstream American English). No effect of stimulus dialect was observed,. Results showed that vocabulary size was a better predictor of eye gaze patterns than maternal education, but that maternal education level had a moderating effect; as maternal education level increased, vocabulary size was less predictive of lexical processing efficiency.

    In the Semantic Web, vocabularies are defined and shared among knowledge workers to describe linked data for scientific, industrial or daily life usage. With the rapid growth of online vocabularies, there is an emergent need for approaches helping users understand vocabularies quickly. In this paper, we study the summarization of vocabularies to help users understand vocabularies. Vocabulary summarization is based on the structural analysis and pragmatics statistics in the global Semantic Web. Local Bipartite Model and Expanded Bipartite Model of a vocabulary are proposed to characterize the structure in a vocabulary and links between vocabularies. A structural importance for each RDF sentence in the vocabulary is assessed using link analysis. Meanwhile, pragmatics importance of each RDF sentence is assessed using the statistics of instantiation of its terms in the Semantic Web. Summaries are produced by extracting important RDF sentences in vocabularies under a re-ranking strategy. Preliminary experiments show that it is feasible to help users understand a vocabulary through its summary.

    The contributions of phonological short-term memory and existing foreign vocabulary knowledge to the learning of new words in a second language were compared in a sample of 40 Greek children studying English at school. The children's speed of learning new English words in a paired-associate learning task was strongly influenced by their current English vocabulary, but was independent of phonological memory skill, indexed by nonword repetition ability. However, phonological memory performance was closely linked to English vocabulary scores. The findings suggest that in learners with considerable familiarity with a second language, foreign vocabulary acquisition is mediated largely by use of existing knowledge representations.

    The current study investigated the role of spatial distance in word learning. Two-year-old children saw three novel objects named while the objects were either in close proximity to each other or spatially separated. Children were then tested on their retention for the name-object associations. Keeping the objects spatially separated from each other during naming was associated with increased retention for children with larger vocabularies. Children with a lower vocabulary size demonstrated better retention if they saw objects in close proximity to each other during naming. This demonstrates that keeping a clear view of objects during naming improves word learning for children who have already learned many words, but keeping objects within close proximal range is better for children at earlier stages of vocabulary acquisition. The effect of distance is therefore not equal across varying vocabulary sizes. The influences of visual crowding, cognitive load, and vocabulary size on word learning are discussed.

    2011-07-15

    Background: Though appropriate image acquisition parameters allow an effective dose below 1 mSv for CT coronary angiography (CTCA) performed with the latest dual-source CT scanners, a single-source 64-detector CT procedure results in a significant radiation dose due to its technical limitations. Therefore, estimating the radiation doses absorbed by an organ during 64-detector CTCA is important. Purpose: To estimate the radiation doses absorbed by organs located in the chest region during 64-detector CTCA using different acquisition techniques and heart rates. Material and Methods: Absorbed doses for breast, heart, lung, red bone marrow, thymus, and skin were evaluated using an anthropomorphic phantom and radiophotoluminescence glass dosimeters (RPLDs). Electrocardiogram (ECG)-gated helical and ECG-triggered non-helical acquisitions were performed by applying a simulated heart rate of 60 beats per minute (bpm) and ECG-gated helical acquisitions using ECG modulation (ECGM) of the tube current were performed by applying simulated heart rates of 40, 60, and 90 bpm after placing RPLDs on the anatomic location of each organ. The absorbed dose for each organ was calculated by multiplying the calibrated mean dose values of RPLDs with the mass energy coefficient ratio. Results: For all acquisitions, the highest absorbed dose was observed for the heart. When the helical and non-helical acquisitions were performed by applying a simulated heart rate of 60 bpm, the absorbed doses for heart were 215.5, 202.2, and 66.8 mGy for helical, helical with ECGM, and non-helical acquisitions, respectively. When the helical acquisitions using ECGM were performed by applying simulated heart rates of 40, 60, and 90 bpm, the absorbed doses for heart were 178.6, 139.1, and 159.3 mGy, respectively. Conclusion: ECG-triggered non-helical acquisition is recommended to reduce the radiation dose. Also, controlling the patients' heart rate appropriately during ECG-gated helical acquisition with

  12. Consolidation of vocabulary during sleep: The rich get richer?

    Science.gov (United States)

    James, Emma; Gaskell, M Gareth; Weighall, Anna; Henderson, Lisa

    2017-06-01

    Sleep plays a role in strengthening new words and integrating them with existing vocabulary knowledge, consistent with neural models of learning in which sleep supports hippocampal transfer to neocortical memory. Such models are based on adult research, yet neural maturation may mean that the mechanisms supporting word learning vary across development. Here, we propose a model in which children may capitalise on larger amounts of slow-wave sleep to support a greater demand on learning and neural reorganisation, whereas adults may benefit from a richer knowledge base to support consolidation. Such an argument is reinforced by the well-reported "Matthew effect", whereby rich vocabulary knowledge is associated with better acquisition of new vocabulary. We present a meta-analysis that supports this association between children's existing vocabulary knowledge and their integration of new words overnight. Whilst multiple mechanisms likely contribute to vocabulary consolidation and neural reorganisation across the lifespan, we propose that contributions of existing knowledge should be rigorously examined in developmental studies. Such research has potential to greatly enhance neural models of learning. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The purpose of this experimental study is to investigate the effects of using content acquisition podcasts (CAPs), an example of instructional technology, to provide vocabulary instruction to adolescents with and without learning disabilities (LD). A total of 279 urban high school students, including 30 with LD in an area related to reading, were randomly assigned to one of four experimental conditions with instruction occurring at individual computer terminals over a 3-week period. Each of the four conditions contained different configurations of multimedia-based instruction and evidence-based vocabulary instruction. Dependent measures of vocabulary knowledge indicated that students with LD who received vocabulary instruction using CAPs through an explicit instructional methodology and the keyword mnemonic strategy significantly outperformed other students with LD who were taught using the same content, but with multimedia instruction that did not adhere to a specific theoretical design framework. Results for general education students mirrored those for students with LD. Students also completed a satisfaction measure following instruction with multimedia and expressed overall agreement that CAPs are useful for learning vocabulary terms.

  15. Strategies for teaching and learning vocabulary

    Directory of Open Access Journals (Sweden)

    Feng Teng

    2014-11-01

    Full Text Available Abstract This article presents an overview of current research on second language vocabulary learning and proposes eight strategies for teaching and learning vocabulary. First, to facilitate effective vocabulary teaching, choosing high-frequency words is essential. Teachers of vocabulary also need to add explicit, intentional teaching to incidental learning. In addition, vocabulary learning strategies including morphological awareness and lexical inference provides a platform by which learners can improve both receptive and productive vocabulary knowledge. This article also suggests that productive vocabulary knowledge needs more attention than receptive vocabulary knowledge, and that available textbooks seldom address vocabulary sufficiently. In summary, it is very important for all learners and teachers to acknowledge that learning vocabulary is incremental in nature, and we should develop a principled, long-term program for teaching and learning vocabulary.

    2017-03-01

    Many adults struggle with second language acquisition, but learn new native-language words relatively easily. We investigated the role of sublexical native-language patterns on novel word acquisition. Twenty English monolinguals learned 48 novel written words in five repeated testing blocks. Half were orthographically wordlike (e.g., nish, high neighborhood density and high segment/bigram frequency), while half were not (e.g., gofp, low neighborhood density and low segment/bigram frequency). Participants were faster and more accurate at recognizing and producing wordlike items, indicating a native-language similarity benefit. Individual differences in memory and vocabulary size influenced learning, and error analyses indicated that participants extracted probabilistic information from the novel vocabulary. Results suggest that language learners benefit from both native-language overlap and regularities within the novel language.

  5. The Effect of Interactivity with a Music Video Game on Second Language Vocabulary Recall

    2010-06-01

    Full Text Available Video games are potential sources of second language input; however, the medium’s fundamental characteristic, interactivity, has not been thoroughly examined in terms of its effect on learning outcomes. This experimental study investigated to what degree, if at all, video game interactivity would help or hinder the noticing and recall of second language vocabulary. Eighty randomly-selected Japanese university undergraduates were paired based on similar English language and game proficiencies. One subject played an English-language music video game for 20 minutes while the paired subject watched the game simultaneously on another monitor. Following gameplay, a vocabulary recall test, a cognitive load measure, an experience questionnaire, and a two-week delayed vocabulary recall test were administered. Results were analyzed using paired samples t-tests and various analyses of variance. Both the players and the watchers of the video game recalled vocabulary from the game, but the players recalled significantly less vocabulary than the watchers. This seems to be a result of the extraneous cognitive load induced by the interactivity of the game; the players perceived the game and its language to be significantly more difficult than the watchers did. Players also reported difficulty simultaneously attending to gameplay and vocabulary. Both players and watchers forgot significant amounts of vocabulary over the course of the study. We relate these findings to theories and studies of vocabulary acquisition and video game-based language learning, and then suggest implications for language teaching and learning with interactive multimedia.

    2017-07-01

    The semantic bootstrapping hypothesis proposes that children acquire their native language through exposure to sentences of the language paired with structured representations of their meaning, whose component substructures can be associated with words and syntactic structures used to express these concepts. The child's task is then to learn a language-specific grammar and lexicon based on (probably contextually ambiguous, possibly somewhat noisy) pairs of sentences and their meaning representations (logical forms). Starting from these assumptions, we develop a Bayesian probabilistic account of semantically bootstrapped first-language acquisition in the child, based on techniques from computational parsing and interpretation of unrestricted text. Our learner jointly models (a) word learning: the mapping between components of the given sentential meaning and lexical words (or phrases) of the language, and (b) syntax learning: the projection of lexical elements onto sentences by universal construction-free syntactic rules. Using an incremental learning algorithm, we apply the model to a dataset of real syntactically complex child-directed utterances and (pseudo) logical forms, the latter including contextually plausible but irrelevant distractors. Taking the Eve section of the CHILDES corpus as input, the model simulates several well-documented phenomena from the developmental literature. In particular, the model exhibits syntactic bootstrapping effects (in which previously learned constructions facilitate the learning of novel words), sudden jumps in learning without explicit parameter setting, acceleration of word-learning (the "vocabulary spurt"), an initial bias favoring the learning of nouns over verbs, and one-shot learning of words and their meanings. The learner thus demonstrates how statistical learning over structured representations can provide a unified account for these seemingly disparate phenomena. Copyright © 2017 Elsevier B.V.

    To evaluate the agreement of fast imaging employing steady-state acquisition (FIESTA) cine technique with segmented k-space fast gradient echo (GRE) cine technique when using them for assessment of cardiac function. Eleven MR cine studies were performed on six healthy volunteers and five patients, using FIESTA and fast GRE techniques. The quantitative measurements of ventricular function obtained from the two techniques were compared. The data analysis was performed by two observers independently. Compared to fast GRE cine technique, FIESTA cine technique consistently resulted in higher end-diastolic volume (10.2%) and end-systolic volume (21.6%), but lower myocardial mass of left ventricle (19.2%) and ejection fraction (9.9%). The stroke volume obtained from the two techniques was very close. The primary explanation for this variability is that the two techniques have different mechanisms on establishing signal contrast. Compared to fast GRE technique, FIESTA provides significantly different results when using it for assessment of left ventricular function. It is important to consider this difference in the assessment of cardiac function. Copyright 2002 Wiley-Liss, Inc.

    Full Text Available This paper seeks to explore through interviews the vocabularies of happiness that interviewees invoke in face-to-face interactions to account for their happiness or lack thereof and, especially, for the (unhappiness of others. In other words, how do respondents present their own or others’ happiness – be they close or distant acquaintances, or people in general, in an interview conversation? Also, what understanding of others do these accounts make visible? This work embraces a discursive psychological (DP perspective, focusing on how different versions of happiness are being put together by respondents presenting themselves as competent and credible individuals, while at the same time positioning themselves in a moral order of happiness.

    Full Text Available The current study made an attempt to compare the impacts of teaching authentic materials through traditional techniques with teaching authentic materials through authentic use, where students in the experimental group were taught new vocabulary items of subtitles through watching subtitled videos, and control group were taught the same vocabulary items from subtitles using traditional instruction of vocabulary. The participants of the study consisted of 36 Iranian students from both genders. In order to ensure the homogeneity of the participants, Oxford Placement Test (2004 was administered. Then they were randomly put into two groups (18 students in each group.  Immediately after the study and three weeks after the study vocabulary tests were administered to the both groups. The results indicated that the students of control group outperformed in short-term retention. However, the experimental group outperformed in long-term retention, indicating the superiority of learning vocabulary through watching subtitled videos in long-term retention of vocabulary. As many learners do not develop long-term mastery of the vocabulary, teaching vocabulary items through watching videos with subtitles can help them store and retrieve vocabulary items better.

    Handbooks recommend a variety of quite complicated procedures for learning and remembering vocabulary, but most learners only engage in very simple procedures. The aim of this project was to establish a basis for identifying optimal vocabulary recording procedures by finding out what learners...... currently do. We administered a questionnaire, interviewed learners who said that they kept vocabulary records of some kind and examined their records. Two-thirds had given up making vocabulary lists on entering the L2 environment and/or starting to read extensively, but several made interesting lists...... to be bilingual and single-word focused. The optimal listing procedures are those which represent a compromise between linguistically and psychologically effective practices and the amount of investment learners are actually prepared to put in. It is important to distinguish records made in class, which should...

    The objective of this work was to measure patient eye lens dose for different cone-beam computed tomography (CBCT) acquisition protocols of Varian's On-Board Imaging (OBI) system using optically stimulated luminescence dosimeter (OSLD) and to study the variation in eye lens dose with patient geometry and distance of isocenter to the eye lens. During the experimental measurements, OSLD was placed on the patient between the eyebrows of both eyes in line of nose during CBCT image acquisition to measure eye lens doses. The eye lens dose measurements were carried out for three different cone-beam acquisition protocols (standard dose head, low-dose head [LDH], and high-quality head [HQH]) of Varian OBI. Measured doses were correlated with patient geometry and distance between isocenter and eye lens. Measured eye lens doses for standard head and HQH protocols were in the range of 1.8-3.2 mGy and 4.5-9.9 mGy, respectively. However, the measured eye lens dose for the LDH protocol was in the range of 0.3-0.7 mGy. The measured data indicate that eye lens dose to patient depends on the selected imaging protocol. It was also observed that eye lens dose does not depend on patient geometry but strongly depends on distance between eye lens and treatment field isocenter. However, undoubted advantages of imaging system should not be counterbalanced by inappropriate selection of imaging protocol, especially for very intense imaging protocol.

  7. Towards very large vocabulary word recognition

    1982-11-01

    In this paper, preliminary considerations and some experimental results are presented in an effort to design Very Large Vocabulary Recognition (VLVR) systems. We will first consider the applicability of current recognition techniques and argue their inadequacy for VLVR. Possible alternate strategies will be explored and their potential usefulness statistically evaluated. Our results indicate that suprasegmental cues such as syllabification, stress patterns, rhythmic patterns, rhythmic patterns and the voiced - unvoiced patterns in the syllables of a word provide powerful mechanisms for search space reduction. Suprasegmental feature could thus operate in a complementary fashion to segmental features.

    Full Text Available This paper presents an educational game which aids learners with foreign lexicon acquisition while entertaining them at the same time. An overview over existing language learning tools is given, and a general platform for educational games for second language acquisition (SLA is described. It introduces a specific prototype video game which teaches Italian vocabulary to the user. The application puts learning at the core of its game mechanics and combines it with a narrative and role-playing elements. In a user study, the game is compared to two other learning methods with focus on long term retention of vocabulary and enjoyment of the exercise. The game is found to perform within 10% of the efficiency of pure vocabulary learning exercises, while being considerably more enjoyable to the user.

  9. Mental Lexicon, Working Memory and L2 (English Vocabulary in Polish Students with and without Dyslexia

    2015-03-01

    Full Text Available The aim of our study was to examine the relationship between access to the mental lexicon, working memory and knowledge of English (L2 vocabulary. Analyses were undertaken amongst monolingual speakers of Polish (26 with dyslexia, 24 without who studied English as a second language as part of their compulsory educational programme at school. We assumed that students with dyslexia would manifest deficits in access to the mental lexicon and verbal working memory, and would have a limited L2 vocabulary. We also assumed that better access to the mental lexicon facilitates knowledge of English (L2 vocabulary, and that this relationship is present in both the criterion and the control group. All of the students participated in both parts of the assessment, the group part (i.e., questionnaire, IQ test, two vocabulary tasks and the individual part (i.e., psychological measures: verbal working memory, RAN, verbal fluency, and single word reading in L1 task. We found that students with dyslexia exhibited deficits in the speed of access to data from the mental lexicon. The predictive function of memory for vocabulary was more conspicuous in the control group; in the criterion group, the result might constitute a risk factor for L2 vocabulary acquisition in dyslexia, which may manifest with increased proficiency in word knowledge. Poor vocabulary knowledge renders the L2 learning experience difficult, as it impairs students’ reading comprehension, writing and conversational skills.

  10. Unsupervised Language Acquisition

    CERN Document Server

    De Marcken, C

    1996-01-01

    This thesis presents a computational theory of unsupervised language acquisition, precisely defining procedures for learning language from ordinary spoken or written utterances, with no explicit help from a teacher. The theory is based heavily on concepts borrowed from machine learning and statistical estimation. In particular, learning takes place by fitting a stochastic, generative model of language to the evidence. Much of the thesis is devoted to explaining conditions that must hold for this general learning strategy to arrive at linguistically desirable grammars. The thesis introduces a variety of technical innovations, among them a common representation for evidence and grammars, and a learning strategy that separates the ``content'' of linguistic parameters from their representation. Algorithms based on it suffer from few of the search problems that have plagued other computational approaches to language acquisition. The theory has been tested on problems of learning vocabularies and grammars from unse...

  11. Exploring cross-linguistic vocabulary effects on brain structures using voxel-based morphometry.

    Green, D W; Crinion, J; Price, C J

    2007-07-01

    Given that there are neural markers for the acquisition of a non-verbal skill, we review evidence of neural markers for the acquisition of vocabulary. Acquiring vocabulary is critical to learning one's native language and to learning other languages. Acquisition requires the ability to link an object concept (meaning) to sound. Is there a region sensitive to vocabulary knowledge? For monolingual English speakers, increased vocabulary knowledge correlates with increased grey matter density in a region of the parietal cortex that is well-located to mediate an association between meaning and sound (the posterior supramarginal gyrus). Further this region also shows sensitivity to acquiring a second language. Relative to monolingual English speakers, Italian-English bilinguals show increased grey matter density in the same region.Differences as well as commonalities might exist in the neural markers for vocabulary where lexical distinctions are also signalled by tone. Relative to monolingual English, Chinese multilingual speakers, like European multilinguals, show increased grey matter density in the parietal region observed previously. However, irrespective of ethnicity, Chinese speakers (both Asian and European) also show highly significant increased grey matter density in two right hemisphere regions (the superior temporal gyrus and the inferior frontal gyrus). They also show increased grey matter density in two left hemisphere regions (middle temporal and superior temporal gyrus). Such increases may reflect additional resources required to process tonal distinctions for lexical purposes or to store tonal differences in order to distinguish lexical items. We conclude with a discussion of future lines of enquiry.

    We have mapped clinically used diagnostic terms from a legacy ambulatory care system to the separate controlled vocabulary of our central clinical information system. The methodology combines elements of lexical and morphologic text matching techniques, followed by manual physician review. Results of the automated matching algorithm before and after partial manual review are presented. The results of this effort will permit the migration of coded clinical data from one system to another. Output from the system after the term review process will be fed back to the target vocabulary via automated and semi-automated means to improve its clinical utility. PMID:7949922

    2014-01-15

    Purpose: The aim of this study was to perform functional MR imaging of the whole heart in a single breath-hold using an undersampled 3 D trajectory for data acquisition in combination with compressed sensing for image reconstruction. Materials and Methods: Measurements were performed using an SSFP sequence on a 3 T whole-body system equipped with a 32-channel body array coil. A 3 D radial stack-of-stars sampling scheme was utilized enabling efficient undersampling of the k-space and thereby accelerating data acquisition. Compressed sensing was applied for the reconstruction of the missing data. A validation study was performed based on a fully sampled dataset acquired by standard Cartesian cine imaging of 2 D slices on a healthy volunteer. The results were investigated with regard to systematic errors and resolution losses possibly introduced by the developed reconstruction. Subsequently, the proposed technique was applied for in-vivo functional cardiac imaging of the whole heart in a single breath-hold of 27 s. The developed technique was tested on three healthy volunteers to examine its reproducibility. Results: By means of the results of the simulation (temporal resolution: 47 ms, spatial resolution: 1.4 x 1.4 x 8 mm, 3 D image matrix: 208 x 208 x 10), an overall acceleration factor of 10 has been found where the compressed sensing reconstructed image series shows only very low systematic errors and a slight in-plane resolution loss of 15 %. The results of the in-vivo study (temporal resolution: 40.5 ms, spatial resolution: 2.1 x 2.1 x 8 mm, 3 D image matrix: 224 x 224 x 12) performed with an acceleration factor of 10.7 confirm the overall good image quality of the presented technique for undersampled acquisitions. Conclusion: The combination of 3 D radial data acquisition and model-based compressed sensing reconstruction allows high acceleration factors enabling cardiac functional imaging of the whole heart within only one breath-hold. The image quality in the

    The aim of this study was to evaluate the frequency of abnormal findings in magnetic resonance imaging (MRI) in children with headache, the clinical relevance of these findings, and whether more sophisticated technologies also result in more relevant abnormal findings. The MRIs of 1004 children with age ranging from 1 to 17 years were retrospectively analyzed. Children who were investigated with established sequences (n = 419) were compared with those examined with state-of-the-art MRI acquisition technology (n = 585). In 216/1004 investigations, MRI was performed because of headache (74/216 with established sequences, 142/216 with state-of-the-art acquisition technology). In 114/216 (52.8%) patients with headache, the MRI was abnormal with relevant findings in 23/114 patients and findings without clinical relevance in 91/114 children. A higher incidence of abnormal findings than in previous reports was found but there was only limited clinical gain of information using modern sequences in children with headache.

    This study examined the effects of a picture racetrack game on the acquisition, maintenance, and generalization of picture labeling for 2 preschool students who are deaf. The game consisted of placing photographs representing individualized target vocabulary around a racetrack board and prompting the participant to sign each photo. A multiple baseline design across picture sets demonstrated that playing the picture racetrack game was functionally related to acquisition of vocabulary to 100% mastery on at least 3 consecutive sessions for each participant. Additionally, both participants maintained most of the vocabulary they acquired for at least 4 weeks after intervention, and they generalized picture labeling to a different presentation mode (i.e., a photo album). © The Author 2017.

    Hermans, Daan; Knoors, Harry; Ormel, Ellen; Verhoeven, Ludo

    2008-01-01

    The acquisition of reading vocabulary is one of the major challenges for deaf children in bilingual education programs. Deaf children have to acquire a written lexicon that can effectively be used in reading. In this paper, we present a developmental model that describes reading vocabulary acquisition of deaf children in bilingual education programs. The model is inspired by Jiang's model of vocabulary development in a second language (N. Jiang, 2000, 2004a) and the hierarchical model of lexical representation and processing in bilinguals (J. F. Kroll & E. Stewart, 1988). We argue that lexical development in the written language often fossilizes and that many words deaf readers acquire will not reach the final stage of lexical development. We argue that this feature is consistent with many findings reported in the literature. Finally, we discuss the pedagogical implications of the model.

    The MacArthur-Bates Communicative Development Inventories (CDIs) are a widely used family of parent-report instruments for easy and inexpensive data-gathering about early language acquisition. CDI data have been used to explore a variety of theoretically important topics, but, with few exceptions, researchers have had to rely on data collected in their own lab. In this paper, we remedy this issue by presenting Wordbank, a structured database of CDI data combined with a browsable web interface. Wordbank archives CDI data across languages and labs, providing a resource for researchers interested in early language, as well as a platform for novel analyses. The site allows interactive exploration of patterns of vocabulary growth at the level of both individual children and particular words. We also introduce wordbankr, a software package for connecting to the database directly. Together, these tools extend the abilities of students and researchers to explore quantitative trends in vocabulary development.

    Vocabulary size is an important criterion to measure one's English proficiency. More words mean more freedom in language use. To many English learners, language skill remains difficult due to insufficient vocabulary. Both learners and teachers should be active to find an appropriate way to improve that condition. So it is necessary to know the feature of vocabulary and some effective ways to enlarge vocabulary size.

    Lexical tone is one of the most prominent features in the phonological representation of words in Chinese. However, little, if any, research to date has directly evaluated how young Chinese children's lexical tone identification skills contribute to vocabulary acquisition and character recognition. The present study distinguished lexical tones from segmental phonological awareness and morphological awareness in order to estimate the unique contribution of lexical tone in early vocabulary acquisition and character recognition. A sample of 199 Cantonese children aged 5-6 years was assessed on measures of lexical tone identification, segmental phonological awareness, morphological awareness, nonverbal ability, vocabulary knowledge, and Chinese character recognition. It was found that lexical tone awareness and morphological awareness were both associated with vocabulary knowledge and character recognition. However, there was a significant relationship between lexical tone awareness and both vocabulary knowledge and character recognition, even after controlling for the effects of age, nonverbal ability, segmental phonological awareness and morphological awareness. These findings suggest that lexical tone is a key factor accounting for individual variance in young children's lexical acquisition in Chinese, and that lexical tone should be considered in understanding how children learn new Chinese vocabulary words, in either oral or written forms.

    A consecutive series of 50 patients (28 males and 22 females) who underwent hepatic magnetic resonance imaging (MRI) from August to December 2011 were enrolled in this study. The appropriate parameters for abdominal MRI scans were determined by comparing the images (TE = 90 and 128 msec) produced using the half-Fourier acquisition single-shot turbo spin-echo (HASTE) technique at different signal acquisition times. The patients consisted of 15 normal patients, 25 patients with a hepatoma and 10 patients with a hemangioma. The TE in a single patient was set to either 90 msec or 128 msec. This was followed by measurements using the four normal rendering methods of the biliary tract system and the background signal intensity using the maximal signal intensity techniques in the liver, spleen, pancreas, gallbladder, fat, muscles and hemangioma. The signal-to-noise and the contrast-to-noise ratios were obtained. The image quality was assessed subjectively, and the results were compared. The signal-to-noise and the contrast-to-noise ratios were significantly higher at TE = 128 msec than at TE = 90 when diseases of the liver, spleen, pancreas, gallbladder, and fat and muscles, hepatocellular carcinomas and hemangiomas, and rendering the hepatobiliary tract system based on the maximum signal intensity technique were involved (p < 0.05). In addition, the presence of artifacts, the image clarity and the overall image quality were excellent at TE = 128 msec (p < 0.05). In abdominal MRI, the breath-hold half-Fourier acquisition single-shot turbo spin-echo (HASTE) was found to be effective in illustrating the abdominal organs for TE = 128 msec. Overall, the image quality at TE = 128 msec was better than that at TE = 90 msec due to the improved signal-to-noise (SNR) and contrast-to-noise (CNR) ratios. Overall, the HASTE technique for abdominal MRI based on a high-magnetic field (3.0 T) at a TE of 128 msec can provide useful data.

  16. The Relationship between Learner Autonomy and Vocabulary Learning Strategies in Iranian EFL Learners with Different Language Proficiency Level

    Full Text Available Vocabulary learning is incredibly noteworthy to English language acquisition. It is unfeasible for a learner to communicate without the required vocabulary. In high education levels, learners are habitually forced to become autonomous and make conscious effort to learn vocabulary outside of the classroom. Consequently, the autonomy of the learners plays an important role in developing and enhancing their vocabulary. Learner autonomy is a huge assistance for learners in vocabulary learning since it provides the learners with numerous diverse privileges such as independency from teacher. The researcher investigated whether there is any statistically significant relationship between learner autonomy and vocabulary learning strategies use in Iranian EFL learners with different language proficiency levels. To meet the above purpose, a total number of 190 male and female EFL learners participated in this study. The methodology underlying this study was quantitative (thorough the administration of two questionnaires and two language proficiency test – TOEFL for advanced group, and Nelson for intermediate level. The quantitative data was analyzed using a set of correlational analysis revealing a significant positive correlation between learner autonomy and vocabulary learning strategies use in high proficient group, and a significant positive relationship between these two constructs in low proficient group, however not as strong as in the advanced group.

    A machine-assisted analysis of traces from crime scenes might be possible with the advent of new high-resolution non-destructive contact-less acquisition techniques for latent fingerprints. This requires reliable techniques for the automatic extraction of fingerprint features from latent and exemplar fingerprints for matching purposes using pattern recognition approaches. Therefore, we evaluate the NIST Biometric Image Software for the feature extraction and verification of contact-lessly acquired latent fingerprints to determine potential error rates. Our exemplary test setup includes 30 latent fingerprints from 5 people in two test sets that are acquired from different surfaces using a chromatic white light sensor. The first test set includes 20 fingerprints on two different surfaces. It is used to determine the feature extraction performance. The second test set includes one latent fingerprint on 10 different surfaces and an exemplar fingerprint to determine the verification performance. This utilized sensing technique does not require a physical or chemical visibility enhancement of the fingerprint residue, thus the original trace remains unaltered for further investigations. No particular feature extraction and verification techniques have been applied to such data, yet. Hence, we see the need for appropriate algorithms that are suitable to support forensic investigations.
