  13. Heavy oils processing materials requirements crude processing

    Energy Technology Data Exchange (ETDEWEB)

    Sloley, Andrew W. [CH2M Hill, Englewood, CO (United States)

    2012-07-01

    Over time, recommended best practices for crude unit materials selection have evolved to accommodate new operating requirements, feed qualities, and product qualities. The shift to heavier oil processing is one of the major changes in crude feed quality occurring over the last 20 years. The three major types of crude unit corrosion include sulfidation attack, naphthenic acid attack, and corrosion resulting from hydrolyzable chlorides. Heavy oils processing makes all three areas worse. Heavy oils have higher sulfur content; higher naphthenic acid content; and are more difficult to desalt, leading to higher chloride corrosion rates. Materials selection involves two major criteria, meeting required safety standards, and optimizing economics of the overall plant. Proper materials selection is only one component of a plant integrity approach. Materials selection cannot eliminate all corrosion. Proper materials selection requires appropriate support from other elements of an integrity protection program. The elements of integrity preservation include: materials selection (type and corrosion allowance); management limits on operating conditions allowed; feed quality control; chemical additives for corrosion reduction; and preventive maintenance and inspection (PMI). The following discussion must be taken in the context of the application of required supporting work in all the other areas. Within that context, specific materials recommendations are made to minimize corrosion due to the most common causes in the crude unit. (author)

  16. PROMOTING INCIDENTAL VOCABULARY LEARNING THROUGH VERBAL DRAMATIZATION OF WORDS

    Directory of Open Access Journals (Sweden)

    Looi-Chin Ch’ng

    2014-12-01

    Full Text Available Despite the fact that explicit teaching of vocabulary is often practised in English as a Second Language (ESL classrooms, it has been proven to be rather ineffective, largely because words are not taught in context. This has prompted the increasing use of incidental vocabulary learning approach, which emphasises on repeated readings as a source for vocabulary learning. By adopting this approach, this study aims to investigate students’ ability in learning vocabulary incidentally via verbal dramatization of written texts. In this case, readers’ theatre (RT is used as a way to allow learners to engage in active reading so as to promote vocabulary learning. A total of 160 diploma students participated in this case study and they were divided equally into two groups, namely classroom reading (CR and RT groups. A proficiency test was first conducted to determine their vocabulary levels. Based on the test results, a story was selected as the reading material in the two groups. The CR group read the story through a normal reading lesson in class while the RT group was required to verbally dramatize the text through readers’ theatre activity. Then, a post-test based on vocabulary levels was carried out and the results were compared. The findings revealed that incidental learning was more apparent in the RT group and their ability to learn words from the higher levels was noticeable through higher accuracy scores. Although not conclusive, this study has demonstrated the potential of using readers’ theatre as a form of incidental vocabulary learning activity in ESL settings.

  17. A Vocabulary Learning Tool for L2 Undergraduates Reading Science and Technology Textbooks

    Hsu, Chihcheng; Yang, Fang-Chuan Ou

    2013-05-01

    Students of English as a second language who major in science and technology use English-language textbooks to ensure that they can read English materials upon graduation. Research indicates that teachers spend little time helping these students on the linguistic complexity of such textbooks. Vocabulary, grammar, and article structure are elements of this complexity, but to many students, these elements can be akin to locked doors. This study presents MyVLS-Reader, which focuses on unlocking the first of these doors-vocabulary-while assisting in reading. With explicit vocabulary learning, students learn and memorize individual vocabulary, but the context is lost if the depth of learning discards context. In implicit vocabulary learning, students acquire vocabulary through repeated exposure to contexts, but repeated encounters with new words are required. Few e-learning systems combine both vocabulary-learning approaches. MyVLS-Reader achieves such synergy by (1) using a keyword setting to provide context-matched vocabulary explanation while reading and (2) embedding multiple learning choices, such as keyword setting, the review and memorization of explicit vocabulary, and the option to ask instructors. This study includes two rounds of evaluations: (1) an evaluation of the learning achievements of control and treatment groups and (2) a quantitative and qualitative investigation of perceptions regarding the use of MyVLS-Reader. The evaluation results indicate that the treatment group developed a better vocabulary than the control group in significantly less time. The use of MyVLS-Reader also slightly improved higher-order thinking skills. This result suggests that MyVLS-Reader can effective assist students in building their vocabulary while reading.

    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

    Full Text Available The significance and impact of vocabulary learning in reading comprehension and L2 language learning are apparent to teachers, researchers and language learners. Moreover, glosses are found as one of the most effective strategies regarding vocabulary retention. Therefore, the present study attempted to investigate the effect of different types of glosses on reading comprehension, vocabulary gain and vocabulary retention. To this end, 140 Iranian EFL learners learning English were selected and were divided into four groups (footnote gloss group, interlinear gloss group, marginal gloss group, and glossary group. They were required to read a text and answer four reading comprehension questions. In addition, one immediate vocabulary post-test and one delayed vocabulary post-test were taken in order to investigate learners' vocabulary gain and vocabulary retention. In order to analyze the data, one one-way ANOVA and one MANOVA were run. The results of one-way ANOVA revealed that participants who received interlinear glosses significantly outperformed the other groups regarding comprehending the text. Moreover, the immediate vocabulary post-test was conducted immediately after reading test and the delayed post-test was administered after four weeks. The results of MANOVA indicated that the group which received interlinear glosses outperformed the other groups in both vocabulary gain and vocabulary retention. The present study has implications for teachers and learners. Teachers can find better methods to teach new reading passages as well as vocabulary items. Also, glosses help learners to have a better comprehension of difficult passages and they facilitate learning. Moreover, learners can enhance their vocabulary knowledge with the help of glosses.

    1995-01-01

    Materials specifications for advanced pressurized water-cooled reactor (APWR) systems are generally based on existing designs, with improved materials and fabrication procedures being developed to counter known degradation effects. In this paper, materials ageing and degradation mechanisms in PWR primary circuit pressure boundary components (i.e. the reactor pressure vessel (RPV), control rod drive mechanisms (CRDMs), coolant piping, coolant pump casing, pressurizer, and steam generators) are reviewed. Important degradation mechanisms include irradiation embrittlement of the RPV, thermal ageing embrittlement of ferritic (e.g. the pressurizer) and cast austenitic (e.g. coolant pump casing and pipe elbows) steel components and environmentally assisted cracking of steam generator tubing and CRDM penetrations. Improved materials specifications and component design and fabrication issues affecting the integrity of the pressure boundary are discussed in the light of these materials problems. Improved fabrication procedures adopted for Sizewell B, such as the utilization of ring forgings to eliminate axial welds in the RPV and steam generator shells and the use of one-piece castings for coolant pump casings, provide a benchmark against which other APWR designs may be judged.

    Full Text Available This study aims at contributing to the investigation on the instruction of EST (English for Science and Technology vocabulary, in terms of receptive use of the language. It evaluates the effectiveness of two teaching approaches to the acquisition of vocabulary. The first approach consisted of teaching vocabulary through the use of dictionaries, where the words were merely translated into the learners’ L1 or defined in the target language thus promoting superficial level of word processing. The second approach employed activities promoting deep level of word processing. Data were analysed quantitatively. Results indicated that the two approaches seem to have some equipotentiality, as far as EST vocabulary is concerned.

    2009-09-01

    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.

In the area of magnetic confinement configurations, attention is given to development programs for first wall materials, which are at various stages for possible austenitic stainless steels, high-strength Fe-Ni-Cr alloys, reactive and refractory metal alloys, specially designed long-range ordered and rapidly solidified alloys, and ferritic/martensitic steels, and for tritium breeding materials, electrical insulators, ceramics, and coolants. The development of materials for inertial confinement reactors is also surveyed in relation to the protection scheme employed for the first wall and the effects of pulsed neutron irradiation. Finally, the materials requirements and selection procedures for the ETF/INTOR and Starfire tokamak reactor designs are examined. Needs for the expansion of research on nonfirst-wall materials and inertial confinement fusion reactor material requirements are pointed out

    Full Text Available Abstract:This present study aimed to investigate 14 kindergarten students of Apple Tree pre-school Samarinda with various ability toward their English vocabularies development by flashcards. A Class Action Research was applied in this study. The data was collected through observation checklist, sequence of cycles and interview transcript. Then, building on the analysis of the collected data, it further discusses the vocabulary development of YL and provides suggestions for TEYL. This study revealed that; (1 most of the students developed their English vocabularies gradually by flashcards. (2 These result indicated that TEYL especially kindergarten students by using flashcards could give significant vocabularies development in learning process. Flashcards is one of the simplest and effective teaching materials for teaching YL vocabulary due to the fact that flashcards are categorized based on themes with full colored pictures which attractive for YL. As this study showed the students were engaged with the topics given since the teachers used flashcards to teach English vocabulary. It was difficult to make engagement with YL in English teaching and learning because YL have different mood, self-motivation, and self-confidence which influenced to the willingness in grasping the lesson. Finally, through this based-picture learning, the students indicated that their progress in vocabulary development although this phenomena was commonly happened in TEFL for YL that lead to teaching method done by English teachers who are required to do more innovation toward their teaching method, to develop sufficient knowledge and to use proper teaching media.

  4. Implications of fusion power plant studies for materials requirements

    International Nuclear Information System (INIS)

    Cook, Ian; Ward, David; Dudarev, Sergei

    2002-01-01

    This paper addresses the key requirements for fusion materials, as these have emerged from studies of commercial fusion power plants. The objective of the international fusion programme is the creation of power stations that will have very attractive safety and environmental features and viable economics. Fusion power plant studies have shown that these objectives may be achieved without requiring extreme advances in materials. But it is required that existing candidate materials perform at least as well as envisaged in the environment of fusion neutrons, heat fluxes and particle fluxes. The development of advanced materials would bring further benefits. The work required entails the investigation of many intellectually exciting physics issues of great scientific interest, and of wider application than fusion. In addition to giving an overview, selected aspects of the science, of particular physics interest, are illustrated

    The energy and material necessary to construct a power plant and the land covered by the plant are indicators for the ‘consumption’ of environment by a certain technology. Based on current knowledge, estimations show that the material necessary to construct a fusion plant will exceed the material...... requirement of a fission plant by a factor of two. The material requirement for a fusion plant is roughly 2000 t/MW and little less than 1000 t/MW for a fission plant. The land requirement for a fusion plant is roughly 300 m2/MW and the land requirement for a fission plant is a little less than 200 m2/MW...... less ‘environment’ for the construction than renewable technologies, especially wind and solar....

    Full Text Available Abstract:  This research investigated 80 students of Diploma III Architecture of Samarinda State Polytechnic to see their vocabularies mastery trough storytelling. Telling the stories is one of the best way to find out the students' English Mastery. Some obstacles are also found in learning English trough performing storytelling in the class such as the suitable material and text for the students, the lack of ability of the students and the teacher in conducting story as well as the readiness and the nervousness of the storytellers. As an English lecturer, the researcher also finds that how to improve vocabularies is one of the students' problems in learning English.  It is proved when the students are asked to tell a story in front of the class. In this research, the students needed telling stories before they had the English vocabulary test.  From the test, it could be concluded that the highest score was 92 got by one (1 student while the lowest score was 46 got by one (1 student.  Meanwhile, the average score was 78 that classified fair (B.  There were two (2 students who got below 50 that classified Fail. The results show that even the students' English mastery were satisfied but the students still need to practice how to tell the story in a good way so that they will master in all aspects.

    1999-12-07

    The work reported here experimentally investigates a striking generalization about vocabulary acquisition: Noun learning is superior to verb learning in the earliest moments of child language development. The dominant explanation of this phenomenon in the literature invokes differing conceptual requirements for items in these lexical categories: Verbs are cognitively more complex than nouns and so their acquisition must await certain mental developments in the infant. In the present work, we investigate an alternative hypothesis; namely, that it is the information requirements of verb learning, not the conceptual requirements, that crucially determine the acquisition order. Efficient verb learning requires access to structural features of the exposure language and thus cannot take place until a scaffolding of noun knowledge enables the acquisition of clause-level syntax. More generally, we experimentally investigate the hypothesis that vocabulary acquisition takes place via an incremental constraint-satisfaction procedure that bootstraps itself into successively more sophisticated linguistic representations which, in turn, enable new kinds of vocabulary learning. If the experimental subjects were young children, it would be difficult to distinguish between this information-centered hypothesis and the conceptual change hypothesis. Therefore the experimental "learners" are adults. The items to be "acquired" in the experiments were the 24 most frequent nouns and 24 most frequent verbs from a sample of maternal speech to 18-24-month-old infants. The various experiments ask about the kinds of information that will support identification of these words as they occur in mother-to-child discourse. Both the proportion correctly identified and the type of word that is identifiable changes significantly as a function of information type. We discuss these results as consistent with the incremental construction of a highly lexicalized grammar by cognitively and pragmatically

  14. Materials requirements for liquid metal fast breeder reactors

    International Nuclear Information System (INIS)

    Bennett, J.W.; Horton, K.E.

    1978-01-01

    Materials requirements for Liquid Metal Fast Breeder Reactors (LMFBRs) are quite varied with requisite applications ranging from ex-reactor components such as piping, pumps, steam generators and heat exchangers to in-reactor components such as heavy section reactor vessels, core structurals, fuel pin cladding and subassembly flow ducts. Requirements for ex-reactor component materials include: good high temperature tensile, creep and fatigue properties; compatibility with high temperature flowing sodium; resistance to wear, stress corrosion cracking, and crack propagation; and good weldability. Requirements for in-reactor components include most of those cited above for ex-reactor components as supplemented by the following: resistance to radiation embrittlement, swelling and radiation enhanced creep; good neutronics; compatibility with fuel and fission product materials; and resistance to mass transfer via flowing sodium. Extensive programs are currently in place in a number of national laboratories and industrial contractors to address the materials requirements for LMFBRs. These programs are focused on meeting the near term requirements of early LMFBRs such as the Fast Flux Test Facility and the Clinch River Breeder Reactor as well as the longer term requirements of larger near-commercial and fully-commercial reactors

    Full Text Available This study was conducted to reveal what Memrise, an online vocabulary study tool, can offer to upper-intermediate EFL learners compared to traditional vocabulary exercises in L2 vocabulary learning. Two groups of upper-intermediate learners (N=80 were randomly assigned to the experimental group and the control group and were given the Vocabulary Knowledge Scale, VKS for short, as the pre-test and post-test. The participants in both groups were exposed to the target vocabulary items in the same reading text. While those in the experimental group created list of target vocabulary items collaboratively in Memrise and then studied the sets individually, the learners in the control group did traditional vocabulary exercises. The results of the post-tests indicated that there was a significant difference between the control group and the experimental group in favor of the experimental group. The researchers discuss possible pedagogical implications of this significant finding for EFL vocabulary instruction.

    1993-01-01

    Under NASA-sponsored High Speed Research (HSR) programs, the materials and processing requirements have been identified for overcoming the environmental and economic barriers of the next generation High Speed Civil Transport (HSCT) propulsion system. The long (2 to 5 hours) supersonic cruise portion of the HSCT cycle will place additional durability requirements on all hot section engine components. Low emissions combustor designs will require high temperature ceramic matrix composite liners to meet an emission goal of less than 5g NO(x) per Kg fuel burned. Large axisymmetric and two-dimensional exhaust nozzle designs are now under development to meet or exceed FAR 36 Stage III noise requirements, and will require lightweight, high temperature metallic, intermetallic, and ceramic matrix composites to reduce nozzle weight and meet structural and acoustic component performance goals. This paper describes and discusses the turbomachinery, combustor, and exhaust nozzle requirements of the High Speed Civil Transport propulsion system.

    2014-05-01

    Full Text Available Vocabulary plays an important role because it links to the four skills of listening, speaking, reading, and writing. Those aspects should be integrated in teaching and learning process of English. However, the students must be able to know the meaning of each word or vocabulary of English in order to master the four skills. It is as a mean to create a sentence in daily communication to show someone’s feeling, opinion, idea, desire, etc. So that, both speakers understand what the other speaker mean. However, English as a second language in Indonesia seems very hard for the students to master vocabulary of English. It makes them not easy to be understood directly and speak fluently. The students, sometimes, get difficulties in understanding, memorizing the meaning of the vocabulary, and getting confused in using the new words. There must be an effective strategy to attract students’ interest, break the boredom, and make the class more lively. Based on the writer experience, Colourful Puzzle Game is able to make the students learn vocabulary quickly. It needs teacher’s creativity to create the materials of this game based on the class condition. The teacher just need a game board made from colourful papers, write any command and prohibition words on it. A dice is a tool to decide where the player should stop based on the number. Some pins as counter as sign of each player.

  2. Packaging configurations and handling requirements for nuclear materials

    International Nuclear Information System (INIS)

    Jefferson, R.M.

    1981-01-01

    The basic safety concepts for radioactive material are that the package is the primary protection for the public, that the protection afforded by the package should be proportional to the hazard and that the package must be proved by performance. These principles are contained in Department of Energy (DOE), Nuclear Regulatory Commission (NRC) and Department of Transportation (DOT) regulations which classify hazards of various radioactive materials and link packaging requirements to the physical form and quantities being shipped. Packaging requirements are reflected in performance standards to guarantee that shipments of low hazard quantities will survive the rigors of normal transportation and that shipments of high hazard quantities will survive extreme severity transportation accidents. Administrative controls provide for segregation of radioactive material from people and other sensitive or hazardous material. They also provide the necessary information function to control the total amounts in a conveyance and to assure that appropriate emergency response activities be started in case of accidents or other emergencies. Radioactive materials shipped in conjunction with the nuclear reactor programs include, ores, concentrates, gaseous diffusion feedstocks, enriched and depleted uranium, fresh fuel, spent fuel, high level wastes, low level wastes and transuranic wastes. Each material is packaged and shipped in accordance with regulations and all hazard classes, quantity limits and packaging types are called into use. From the minimal requirements needed to ship the low hazard uranium ores or concentrates to the very stringent requirements in packaging and moving high level wastes or spent fuel, the regulatory system provides a means for carrying out transportation of radioactive material which assures low and controlled risk to the public

    Full Text Available Vocabulary plays pivotal role in foreign language learning. However, vocabulary teaching and vocabulary learning in TEFL seems to be neglected. The study was aimed to investigate how vocabulary teaching and learning are perceived by teacher and students, strategies to teach and learn the vocabulary, and also influences of students’ vocabulary learning strategy on their vocabulary mastery. Accordingly, a mix method design was employed to one English teacher and 30 junior high school students to reveal the issues being investigated. The findings showed that both teacher and students have positive response on vocabulary teaching and learning. Concerning strategies, it was found that teacher mostly employed Fully-contextual strategy, meanwhile Determination and Metacognitive strategy were found as the most favored VLS chosen by students. The study also confirmed that there is a significant relationship between students’ vocabulary learning strategy and their vocabulary mastery (r-value Discovery = .023 and r-value Consolidating = .000, p<.05. It is recommended for EFL teachers to give a bigger portion to vocabulary in the EFL teaching and to teach vocabulary using the combination of fully-contextual and de-contextual strategy. It is also suggested to introduce students to various kinds of vocabulary learning strategies.

    This paper addresses issues related to the public perception of the regulatory test standards and performance requirements for packaging and transporting radioactive material. Specifically, it addresses the adequacy of the package performance standards and testing for Type B packages, which are those packages designed for transporting the most hazardous quantities and forms of radioactive material. Type B packages are designed to withstand accident conditions in transport. To improve public perception, the public needs to better understand: (a) the regulatory standards and requirements themselves, (b) the extensive history underlying their development, and (c) the soundness of the technical foundation. The public needs to be fully informed on studies, tests, and analyses that have been carried out worldwide and form the basis of the regulatory standards and requirements. This paper provides specific information aimed at improving the public perception of packages test standards

    International Nuclear Information System (INIS)

    Ting, P.

    1991-01-01

    This paper reports that the U.S. Nuclear Regulatory Commission has defined material control and accounting (MC and A) requirement for low-enriched uranium enrichment plants licensed under 10 CFR parts 40 and 70. Following detailed assessment of potential safeguards issues relevant to these facilities, a new MC and A rule was developed. The primary safeguards considerations are detection of the loss of special nuclear material, detection of clandestine production of special nuclear material of low strategic significance for unauthorized use or distribution, and detection of unauthorized production of uranium enriched to ≥10 wt % U-235. The primary safeguards concerns identified were the large absolute limit of error associated with the material balance closing, the inability to shutdown some uranium enrichment technologies to perform a cleanout inventory of the process system, and the flexibility of some of these technologies to produce higher enrichments. Unauthorized production scenarios were identified for some technologies that could circumvent the detection of the production and removal of 5 kilograms of U-235 as high-enriched uranium through conventional material control and accounting programs. Safeguards techniques, including the use of production and process control information, measurements, and technical surveillance, were identified to compensate for these concerns

  15. Water Quality Vocabulary Development and Deployment

    Simons, B. A.; Yu, J.; Cox, S. J.

    2013-12-01

    Semantic descriptions of observed properties and associated units of measure are fundamental to understanding of environmental observations, including groundwater, surface water and marine water quality. Semantic descriptions can be captured in machine-readable ontologies and vocabularies, thus providing support for the annotation of observation values from the disparate data sources with appropriate and accurate metadata, which is critical for achieving semantic interoperability. However, current stand-alone water quality vocabularies provide limited support for cross-system comparisons or data fusion. To enhance semantic interoperability, the alignment of water-quality properties with definitions of chemical entities and units of measure in existing widely-used vocabularies is required. Modern ontologies and vocabularies are expressed, organized and deployed using Semantic Web technologies. We developed an ontology for observed properties (i.e. a model for expressing appropriate controlled vocabularies) which extends the NASA/TopQuadrant QUDT ontology for Unit and QuantityKind with two additional classes and two properties (see accompanying paper by Cox, Simons and Yu). We use our ontology to populate the Water Quality vocabulary with a set of individuals of each of the four key classes (and their subclasses), and add appropriate relationships between these individuals. This ontology is aligned with other relevant stand-alone Water Quality vocabularies and domain ontologies. Developing the Water Quality vocabulary involved two main steps. First, the Water Quality vocabulary was populated with individuals of the ObservedProperty class, which was determined from a census of existing datasets and services. Each ObservedProperty individual relates to other individuals of Unit and QuantityKind (taken from QUDT where possible), and to IdentifiedObject individuals. As a large fraction of observed water quality data are classified by the chemical substance involved, the

    Canada is a major producer and shipper of radioactive material. Each year more than a million packages are transported in Canada. The safety record with the transport of RAM in Canada has historically been excellent. There have never been any serious injuries, overexposure or fatality or environmental consequences attributable to the radioactive nature of such material being transported or being involved in a transport accident. In Canada, the Canadian Nuclear Safety Commission (CNSC) is the prime agency of the federal government entrusted with regulating all activities related to the use of nuclear energy and nuclear substances including the packaging and transport of nuclear substances. The mission of the CNSC is to regulate the use of nuclear energy and materials to protect health, safety, security of the person and the environment and to respect Canada's international commitments on the peaceful use of nuclear energy. The division of responsibility for the regulation of transport of radioactive material has been split between Transport Canada and the CNSC. The governing Transport Canada's regulations are Transport of Dangerous Goods (TDG) Regulations and the CNSC regulations are Packaging and Transport of Nuclear Substances Regulations (PTNSR). Canada has actively participated in the development of the IAEA regulations for the safe transport of radioactive material since 1960. As an IAEA member state, Canada generally follows the requirements of IAEA regulations with few deviations. The Nuclear Safety and Control Act (NSCA) strongly supports Canada's international obligations to ensure safe packaging, transport, storage and disposal of nuclear substances, prescribed equipment and prescribed information. Prescribed equipment and prescribed information are defined in the CNSC General Nuclear Safety and Control Regulations. This paper presents the current CNSC regulatory requirements and initiatives taken by the CNSC to improve its effectiveness and

    Full Text Available Reading passages contain many new words. Looking up every word in the dictionary and finding the exact meaning can be a difficult job for learners and may hinder the process of reading. Providing glosses can help learners deal with this issue. The objective of the present study is to make enquiries about the effect of glosses on incidental vocabulary learning. To this end, 45 Iranian EFL learners were selected from 70 according to their performance on KET test. Then they were divided into three groups of 15 randomly. Ten reading texts were selected and unfamiliar vocabularies were glossed in three ways: pictorial, textual and pictorial-textual glosses. Participants were required to read the texts under one of the three conditions. After the completion of ten sessions of treatment, participants were given a vocabulary post-test to measure vocabulary learning. The outcome of the study indicated that the group that received the combination of pictorial and textual glosses outperformed the other two groups. The findings can be of great importance for language teachers and material developers.

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

    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 (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 socioeconomic 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. PMID:22235920

    2011-01-01

    Since more than a decade illicit Trafficking of hazardous ( CBRNE), materials ( chemical, biological, radiological, nuclear and explosive ) has been identified as a key threat in national, regional, inter regional and international strategies. An Effective response to hazardous materials (CBRNE) risk and threat were realized to require a very high level of cooperation and coordination between various governments and their responsible organizations and authorities of regional and international partner. While improper policy of actions may easily be exploited by non- state members to (CBRNE) trafficking which may lead to develop weapon of mass destruction (WMD). Such strategy are of paramount important between all levels of the states and among regional agreements through comprehensive tailored assistance packages (e.g. export control, illicit trafficking of hazardous materials, redirection of scientist, emergency planning, crisis response safety and security culture. Capacity building, action plans and instruments for stability are necessary actions for efficient combating against illicit trafficking of hazardous materials. Regarding the needs of assessment phase, assistance must be based on data collection, analysis and prioritization of implanting the regulatory controls. Several activities have to be conducted to reduce CBRNE threat. The one- by- one approach, covering either nuclear and radioactive or chemical or biological materials has to be implanted on the country basis performance to mitigate CBRNE hazardous risk. On several consequent phases of intervention dealing with CBRNE risk mitigation the country has to establish a network of local, regional and international capabilities. Such network is setting up the mechanism for the country needs identifications, the guidelines for data collection, for data platform maintenance and update, the data assessment and the competent and operative organizations. This network will be to strengthen the long - term

    2009-01-01

    Different types of cranes, hoists, chain pulley blocks are the most commonly used material handling equipment in industry along with attachments like chains, wire rope slings, d-shackles, etc. These equipment are used at work for transferring loads from one place to another and attachments are used for anchoring, fixing or supporting the load. Selection of the correct equipment, identification of the equipment planning of material handling operation, examination/testing of the equipment, education and training of the persons engaged in operation of the material handling equipment can reduce the risks to safety of people in workplace. Different safety systems like boom angle indicator, overload tripping device, limit switches, etc. should be available in the cranes for their safe use. Safety requirement for safe operation of material handling equipment with emphasis on different cranes and attachments particularly wire rope slings and chain slings have been brought out in this paper. An attempt has also been made to bring out common nature of deficiencies observed during regulatory inspection carried out by AERB. (author)

    1987-09-01

    The NRC is considering a possible rulemaking that would require certain nuclear materials licensees to demonstrate financial ability to clean up accidental releases of radioactive materials. The rulemaking would potentially affect approximately 16,350 NRC and Agreement State licensees. This report was prepared for NRC by the Pacific Northwest Laboratory to provide background information and analysis for the potential rulemaking. Specific topics examined in the report include: (1) characteristics of potentially affected licensees, (2) the availability and cost of various financial assurance mechanisms, (3) the financial impacts for licensees (including licensees classified as small businesses) of providing $2M of assurance per licensee and a sliding amount of assurance tied to risk, (4) the cost of administering a financial assurance rule, and (5) overall benefits and costs. Tabular information on past material licensee accidents and cleanup efforts is also included. The financial occurrence mechanism that appears to be most suitable for providing the desired financial assurance is one or more newly formed captive insurance companies. Potential benefits of the rulemaking include reduced need for taxpayer-funded cleanup of accidental releases, reduces administrative time to secure such funds, and the possibility of more cleanup with correspondingly reduced occupational and public exposure to radioactive materials

  4. Components for Maintaining and Publishing Earth Science Vocabularies

    Science.gov (United States)

    Cox, S. J. D.; Yu, J.

    2014-12-01

    Shared vocabularies are an important aid to geoscience data interoperability. Many organizations maintain useful vocabularies, with Geologic Surveys having a particularly long history of vocabulary and lexicon development. However, the mode of publication is heterogeneous, ranging from PDFs and HTML web pages, spreadsheets and CSV, through various user-interfaces and APIs. Update and maintenance ranges from tightly-governed and externally opaque, through various community processes, all the way to crowd-sourcing ('folksonomies'). A general expectation, however, is for greater harmonization and vocabulary re-use. In order to be successful this requires (a) standardized content formalization and APIs (b) transparent content maintenance and versioning. We have been trialling a combination of software dealing with registration, search and linking. SKOS is designed for formalizing multi-lingual, hierarchical vocabularies, and has been widely adopted in earth and environmental sciences. SKOS is an RDF vocabulary, for which SPARQL is the standard low-level API. However, for interoperability between SKOS vocabulary sources, a SKOS-based API (i.e. based on the SKOS predicates prefLabel, broader, narrower, etc) is required. We have developed SISSvoc for this purpose, and used it to deploy a number of vocabularies on behalf of the IUGS, ICS, NERC, OGC, the Australian Government, and CSIRO projects. SISSvoc Search provides simple search UI on top of one or more SISSvoc sources. Content maintenance is composed of many elements, including content-formalization, definition-update, and mappings to related vocabularies. Typically there is a degree of expert judgement required. In order to provide confidence in users, two requirements are paramount: (i) once published, a URI that denotes a vocabulary item must remain dereferenceable; (ii) the history and status of the content denoted by a URI must be available. These requirements match the standard 'registration' paradigm which is

    To ensure the safe disposal of nuclear wastes, all potential pathways for radionuclide release to the biosphere must be effectively sealed. This report presents a summary of the literature up to August 1982 and outlines the placement, mechanical property and durability-stability requirements for borehole sealing. An outline of the materials that have been considered for possible use in borehole sealing is also included. Cement grouts are recommended for further study since it is indicated in the literature that cement grouts offer the best opportunity of effectively sealing boreholes employing present technology. However, new and less well known materials should also be researched to ensure that the best possible borehole plugging system is developed. 78 refs

    Higher focusable power in neodymium glass fusion lasers can be obtained through the use of new materials with lower nonlinear index (n 2 ) and better energy storage capabilities than the presently employed silicate glass. Silicate, phosphate, fluorophosphate, and beryllium fluoride glasses are discussed in terms of fusion laser requirements, particularly those for the proposed Nova laser. Examples of the variation in spectroscopic and optical properties obtainable with compositional changes are given. Results of a system evaluation of potential laser materials show that fluorophosphate glasses have many of the desired properties for use in Nova. These glasses are now being cast in large sizes (30-cm diameter) and will be tested in prototype amplifiers in 1978

  9. The relationship between Iranian EFL learners’ self-regulatory vocabulary strategy use and their vocabulary size

    Directory of Open Access Journals (Sweden)

    Seyed Mohammad Reza Amirian

    2015-07-01

    Full Text Available Self-regulation is referred to as learners’ self-generated ideas and actions which are systematically directed towards achieving educational goals and require learners’ active participation in the learning process (Zimmerman & Bandura, 1994. The present study investigated the relationship between Iranian EFL students’ self-regulation capacity for vocabulary learning and their vocabulary size. For this purpose, the researchers made use of two main instruments: the self-regulation capacity in vocabulary learning scale developed by Tseng et al. (2006 consisting of five subscales of commitment, metacognitive, emotion, satiation and environment control, and a bilingual vocabulary size test developed and validated by Karami (2012. The results of the data analysis revealed no significant relationship between the two variables measured by these instruments. However, the results of the multiple regressions indicated that the metacognitive control compared to the other subscales made a better contribution to the prediction of learners’ vocabulary size. In addition, based on the analysis of variance (ANOVA, which examined and compared the self-regulatory strategy use of learners in different experience groups, the first year students had a higher mean score in their self-regulation capacity, which can possibly be attributed to the strategies they have learnt in their Study Skills courses. Finally, it was suggested that teachers must try to develop self-regulatory power in the learners because their creative effort and informed decisions in trying to improve their own learning are highly important.

  10. Quality assurance requirements for packaging and transportation of radioactive materials

    International Nuclear Information System (INIS)

    Barker, R.F.; MacDonald, C.E.; Doda, R.J.

    1978-01-01

    This paper discusses the new quality assurance regulations of the Nuclear Regulatory Commission (NRC) for packaging and transportation of radioactive materials. These regulations became effective on October 18, 1977. Background information concerning these regulations and packaging and transportation history is included. The quality assurance program is described with indications of how it is composed of general (administrative) provisions which must meet the 18 quality assurance criteria and be approved by the NRC; specific provisions which appear in the DOT and NRC regulations and in the individual package design approval; and other specific procedures which are not required by regulations but which are necessary for the proper control of quality. The quality assurance program is to be developed using a graded approach for the application of pertinent criteria and optimizing the required degree of safety and control efforts involved in achieving this level of safety. The licensee-user is responsible for all phases of quality assurance for packaging activities including: design, manufacture, test, use, maintenance and repair. The package design phase is considered to be particularly important in producing adequate safety in operational activities concerning packaging and transportation of radioactive materials

  11. Dose requirements for microbial decontamination of botanical materials by irradiation

    International Nuclear Information System (INIS)

    Razem, D.; Katusin-Razem, Branka

    2002-01-01

    Microbial contamination levels and corresponding resistivities to irradiation (expressed as dose required for the first 90% reduction, D first 9 0% r ed ) were analyzed in a number of various botanical materials. The following generalizations could be made: total aerobic plate count is the most informative measure of contamination; the probability of contamination depends on available surface of the material and processing history: flowers and leaves usually contain more contamination than fruits and seeds, while crude herbs contain more than extracts; liquid extracts are more contaminated than dry ones. At the same time, resistivity to irradiation increases approximately in the reverse order of contamination level on going from flowers and leaves, to fruits and seeds, to liquid and dry extracts. The two quantities, probability of contamination and D first 9 0% r ed being inversely related, the treatment dose needed to reduce initial contamination to tolerable level amounts to between 4 and 30 kGy under a typical scenario, and between 8 and 40 kGy under the worst-case scenario for the whole range of raw materials and botanical products

    O'Toole, Ciara; Fletcher, Paul

    2012-01-01

    Investigations into early vocabulary development, including the timing of the acquisition of nouns, verbs and closed-class words, have produced conflicting results, both within and across languages. Studying vocabulary development in Irish can contribute to this area, as it has potentially informative features such as a VSO word order, and semantically rich prepositions. This study used a parent report adapted for Irish, to measure vocabulary development longitudinally for children aged between 1,04 and 3,04. The findings indicated that the children learned closed-class words at relatively smaller vocabulary sizes compared to children acquiring other languages, and had a strong preference for nouns.

    This preliminary edition was prepared at the Board's request to help it establish a standardized terminology. It was produced by scanning the 99 French and English documents listed at the end of this Vocabulary. The documents include legislation concerning atomic energy and the transportation of radioactive materials, as well as the Board's publications, such as the Consultative Documents, Regulatory Documents and Notices. The terms included from the following areas are: radiation protection, reactor technology, nuclear fuel cycle, radioactive material packaging and transportation, radioactive waste management, uranium mines, and medical and industrial applications of radioelements. Also included are the titles of publications and the names of organizations and units. The vocabulary contains 2,589 concepts, sometimes accompanied by definitions, contexts or usage examples. Where terms have been standardized by the Canadian Committee for the Standardization of Nuclear Terminology, this has been indicated. Where possible, we have verified the terms using the TERMIUM, the Government of Canada Linguistic Data Bank. (author)

    In 2004, three new important laws were passed concerning radiotherapy services. The first two concerns the internal and external quality control of linear accelerators and the last concerns the role of the medical physicist, whose presence was made mandatory during the whole length of the treatments. These laws, which aim to improve the quality and the security of treatments, represent an increase in price that we have calculated, and which prevents them being implemented, as a joint study realised by the SFRO and the SFPM has shown. The cost of quality in radiotherapy requires investment in material and manpower and improvement in availability of the accelerators which entails a complete reorganization of the services. Cost analysis is included. The difficulties in implementing these laws have also been evaluated and this evaluation already enables us to propose certain elements enabling us to go forward to globally improve the quality and security in radiotherapy.

    Full Text Available This case study was carried out in the English Education Department of State University of Malang. The aim of the study was to identify and describe the vocabulary in the reading text and to seek if the text is useful for reading skill development. A descriptive qualitative design was applied to obtain the data. For this purpose, some available computer programs were used to find the description of vocabulary in the texts. It was found that the 20 texts containing 7,945 words are dominated by low frequency words which account for 16.97% of the words in the texts. The high frequency words occurring in the texts were dominated by function words. In the case of word levels, it was found that the texts have very limited number of words from GSL (General Service List of English Words (West, 1953. The proportion of the first 1,000 words of GSL only accounts for 44.6%. The data also show that the texts contain too large proportion of words which are not in the three levels (the first 2,000 and UWL. These words account for 26.44% of the running words in the texts.  It is believed that the constraints are due to the selection of the texts which are made of a series of short-unrelated texts. This kind of text is subject to the accumulation of low frequency words especially those of content words and limited of words from GSL. It could also defeat the development of students' reading skills and vocabulary enrichment.

    Jackson, Carla Wood; Schatschneider, Christopher; Leacox, Lindsey

    2014-01-01

    The authors of this study described developmental trajectories and predicted kindergarten performance of Spanish and English receptive vocabulary acquisition of young Latino/a English language learners (ELLs) from socioeconomically disadvantaged migrant families. In addition, the authors examined the extent to which gender and individual initial performance in Spanish predict receptive vocabulary performance and growth rate. The authors used hierarchical linear modeling of 64 children's receptive vocabulary performance to generate growth trajectories, predict performance at school entry, and examine potential predictors of rate of growth. The timing of testing varied across children. The ELLs (prekindergarten to 2nd grade) participated in 2-5 testing sessions, each 6-12 months apart. The ELLs' average predicted standard score on an English receptive vocabulary at kindergarten was nearly 2 SDs below the mean for monolingual peers. Significant growth in the ELLs' receptive vocabulary was observed between preschool and 2nd grade, indicating that the ELLs were slowly closing the receptive vocabulary gap, although their average score remained below the standard score mean for age-matched monolingual peers. The ELLs demonstrated a significant decrease in Spanish receptive vocabulary standard scores over time. Initial Spanish receptive vocabulary was a significant predictor of growth in English receptive vocabulary. High initial Spanish receptive vocabulary was associated with greater growth in English receptive vocabulary and decelerated growth in Spanish receptive vocabulary. Gender was not a significant predictor of growth in either English or Spanish receptive vocabulary. ELLs from low socioeconomic backgrounds may be expected to perform lower in English compared with their monolingual English peers in kindergarten. Performance in Spanish at school entry may be useful in identifying children who require more intensive instructional support for English vocabulary

    2018-01-01

    Full Text Available This study investigated the relationship between vocabulary size and reading comprehension performance among students in a tertiary institution in a Malaysian context and examined the vocabulary size required for students to achieve reading comprehension at various levels of proficiency. The research questions that guided this study were: 1 What is the vocabulary size of second year diploma students studying Mass Communication?; 2 What is the reading comprehension proficiency of second year diploma students studying Mass Communication?; and 3 What vocabulary size is required for different levels of reading comprehension proficiency? This study used the quantitative approach. The participants were 53 Malaysian second-year students at a private university college in Malaysia who were reading for their Diploma in Mass Communication. The instruments used were the Vocabulary Size Test and the IELTS Reading Test (Academic Module. The findings showed that the average vocabulary size of the students was just over 6000 word families and this vocabulary size was generally insufficient for adequate reading comprehension. Students needed an average vocabulary size of about 8000 word families to achieve adequate reading comprehension and about 10000 word families to achieve proficient reading comprehension. Based on the individual student’s performance, this study did not find a linear relationship between vocabulary size and reading comprehension performance, nor was there a threshold vocabulary size for adequate reading comprehension.

  3. 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.

By moving, modifying, and/or adding light during nighttime, inclement weather, or in sharp turns, the driver is presented with dynamic illumination not possible with static lighting systems The objective of this GM-HRL collaborative research project was to assess the potential of active materials to decrease the cost, mass, and packaging volume of current electric stepper-motor AFS designs. Solid-state active material actuators, if proved suitable for this application, could be less expensive than electric motors and have lower part count, reduced size and weight, and lower acoustic and EMF noise1. This paper documents Part 1 of the collaborative study, assessing technically mature, commercially available active materials for use as actuators. Candidate materials should reduce cost and improve AFS capabilities, such as increased angular velocity on swivel. Additional benefits to AFS resulting from active materials actuators were to be identified as well such as lower part count. In addition, several notional approaches to AFS were documented to illustrate the potential function, which is developed more fully in Part 2. Part 1 was successful in verifying the feasibility of using two active materials for AFS: shape memory alloys, and piezoelectrics. In particular, this demonstration showed that all application requirements including those on actuation speed, force, and cyclic stability to effect manipulation of the filament assembly and/or the reflector could be met by piezoelectrics (as ultrasonic motors) and SMA wire actuators.

    2013-12-01

    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.

  19. INCIDENTAL VOCABULARY LEARNING THROUGH READING

    Directory of Open Access Journals (Sweden)

    Holly Warzecha, M.A. TESOL

    2017-04-01

    Full Text Available The purpose of the following paper is to take a closer look at the benefits of incidental learning through reading, with a specific focus on vocabulary acquisition. The teaching of vocabulary has traditionally been an explicit process where the target vocabulary is taken out of context and taught separately. However, this kind of explicit teaching and learning may only take into account a form-meaning connection. Therefore, this paper explores research on incidental learning and specifically looks at what it takes to acquire new vocabulary incidentally through reading while considering the coverage rates of texts, how many words must be known already from the text, how many repetitions it takes to learn a word, types of texts that promote learning, and the effects of pairing students‘ reading with learner tasks. After reviewing many studies, it can be concluded that more reading is better. More specifically, extensive reading of chosen novels at an appropriate level and interest to the students showed important gains in vocabulary. In addition, readings that were supplemented with additional activities that focused on both form and meaning showed an even higher increase in word retention.

  4. Semiconductive Nanostructures - Materials for Spinelectronics: New Data Bank Requirement

    Directory of Open Access Journals (Sweden)

    Paata J Kervalishvili

    2007-12-01

    Full Text Available Nanoscience, the interdisciplinary science that draws on physics, chemistry, biology, and computational mathematics, is still in its infancy. Control and manipulation on a nanometric scale allow the fabrication of nanostructures, the properties of which are mainly determined by quantum mechanics and differ considerably from that of the common crystalline state. Nanostructures constructed from inorganic solids such as semiconductors have new electronic and optical properties because of their size and quantization effects [1, 2]. The quantization effects reflect the fundamental characteristics of structures as soon as their size falls below a certain limit. An example of the simplest nanostructure is the quantum dot formed from the energy well of certain semiconductor materials with 5-10nm thickness sandwiched between other semiconductors with normal properties. Quantum dots, for example, have led to important novel technology for lasers, optical sensors, and other electronic devices. The application of nanolayers to data storage, switching, lighting, and other devices can lead to substantially new hardware, for example, energy cells, and eventually to the quantum-based internet. Nanoscience and nanotechnology encompass the development of nano-spinelectronics, spinelectronics materials production, and nano-spinelectronic measuring devices and technologies. Nano-spinelectronics, based on usage of magnetic semiconductors, represents a new and emerging area of science and engineering of the 21st century. It is a primary example of the creation and enhancement of new materials and devices for information technologies, operating with charge and spin degrees of freedom of carriers, free from present-day limitations. This new multi-disciplinary direction of science and technology is very much in need of support from new data banks, which will function as a source of new ideas and approaches.

    2015-01-01

    Graphical abstract: Critical and precious materials requirement in the wind energy system in the EU 27 by 2020. - Highlights: • The critical and precious materials consumption were calculated in wind energy system in the EU 27. • The future requirement of critical and precious materials was estimated in the EU 27 by 2020. • Fluorspar, silver, magnesium, indium, gold and tantalum are the mainly used and required materials. • This research approach could be applied to other industrial sectors as well as other renewable technology. - Abstract: Critical materials as well as rare earth elements and precious metals such as platinum, gold and silver are used significantly for computer hard disk drives, mobile phones, hybrid electric vehicles, batteries, renewable energy system and many other applications. It is therefore important to quantify and estimate both current stocks and flows of such materials, as well as future requirement for industries and economies. In this study, which is focused on wind energy system in the European Union (EU) 27, the current consumption and future requirement of critical and precious materials were calculated and estimated using the wind power production dataset from ecoinvent and data from National Renewable Energy Action Plan (NREAP). It is shown that fluorspar has been the most consumed material to date, and will probably be the most required material in the future. Among other critical and valuable materials, the main materials used for current wind energy system are silver, magnesium, indium, gold and tantalum. These materials will also be required significantly by 2020 for the wind energy system in the EU 27. It is argued that these results should be connected to the future energy and material policy and management

  2. New concepts for building vocabulary for cell image ontologies.

    Science.gov (United States)

    Plant, Anne L; Elliott, John T; Bhat, Talapady N

    2011-12-21

    There are significant challenges associated with the building of ontologies for cell biology experiments including the large numbers of terms and their synonyms. These challenges make it difficult to simultaneously query data from multiple experiments or ontologies. If vocabulary terms were consistently used and reused across and within ontologies, queries would be possible through shared terms. One approach to achieving this is to strictly control the terms used in ontologies in the form of a pre-defined schema, but this approach limits the individual researcher's ability to create new terms when needed to describe new experiments. Here, we propose the use of a limited number of highly reusable common root terms, and rules for an experimentalist to locally expand terms by adding more specific terms under more general root terms to form specific new vocabulary hierarchies that can be used to build ontologies. We illustrate the application of the method to build vocabularies and a prototype database for cell images that uses a visual data-tree of terms to facilitate sophisticated queries based on a experimental parameters. We demonstrate how the terminology might be extended by adding new vocabulary terms into the hierarchy of terms in an evolving process. In this approach, image data and metadata are handled separately, so we also describe a robust file-naming scheme to unambiguously identify image and other files associated with each metadata value. The prototype database http://sbd.nist.gov/ consists of more than 2000 images of cells and benchmark materials, and 163 metadata terms that describe experimental details, including many details about cell culture and handling. Image files of interest can be retrieved, and their data can be compared, by choosing one or more relevant metadata values as search terms. Metadata values for any dataset can be compared with corresponding values of another dataset through logical operations. Organizing metadata for cell imaging

    This Code of Practice has been prepared as a guide for designers who require packaging for fissile materials. It should be noted that this document covers design requirements only and it is not a manufacturing specification which can be quoted on a manufacturing contract without qualification. Compliance with the regulations regarding the safe transport of fissile materials may be achieved by the provision of an effective shield embodying:- (a) a moderating material -usually one rich in hydrogen, such as wood - in order to thermalise incoming neutrons, and (b) a material - such as cadmium - with a large absorption cross-section for thermal neutrons, located between the moderator and the fissile material, in order to capture the incoming neutrons. This Code describes the requirements in two sections, one for each of these materials. (author)

    2003-12-01

    When constructing stimuli for experimental investigations of cognitive processes in early reading development, researchers have to rely on adult or American children's word frequency counts, as no such counts exist for English children. The present paper introduces a database of children's early reading vocabulary, for use by researchers and teachers. Texts from 685 books from reading schemes and story books read by 5-7 year-old children were used in the construction of the database. All words from the 685 books were typed or scanned into an Oracle database. The resulting up-to-date word frequency list of early print exposure in the UK is available in two forms from a website address given in this paper. This allows access to one list of the words ordered alphabetically and one list of the words ordered by frequency. We also briefly address some fundamental issues underlying early reading vocabulary (e.g., that it is heavily skewed towards low frequencies). Other characteristics of the vocabulary are then discussed. We hope the word frequency lists will be of use to researchers seeking to control word frequency, and to teachers interested in the vocabulary to which young children are exposed in their reading material.

    Full Text Available The study aimed to investigate (a the effect of digital games, songs, and flashcards on vocabulary knowledge of Iranian EFL preschool learners and (b the young learners‟ performance on mid-course tests of vocabulary with different topics. The participants included 350 preschool female learners in Oshnaviyeh, a town in Western Azarbaijan Province and were divided into three tablet, song, and traditional groups. Pre and post-tests of vocabulary and four mid-course tests based, on the learnt vocabularies, were administered during the research. The materials also consisted of a digital game, 16 songs, a structured student book, a workbook, and 60 flashcards. The analysis of the data revealed that there was no significant difference in the vocabulary knowledge of preschool learners who learnt vocabularies via games, songs, and flashcards. The results also showed that there was a significant difference in the three groups‟ mid-course tests with different topics. The findings recommend that using different techniques in the classroom considering learners‟ interest and needs can improve vocabulary knowledge of young learners.

    2004-01-01

    Language independent `bag-of-words' representations are surprisingly effective for text classification. The representation is high dimensional though, containing many non-consistent words for text categorization. These non-consistent words result in reduced generalization performance of subsequent...... of term relevancy, when pruning the vocabularies. With reduced vocabularies documents are classified using a latent semantic indexing representation and a probabilistic neural network classifier. Reducing the bag-of-words vocabularies with 90%-98%, we find consistent classification improvement using two...

    Full Text Available Appropriate conditions and suitable materials can inspire young children to learn a new language effortlessly. The present study attempted to investigate the effects of English talking toys as teaching materials on vocabulary learning of very young learners (VYL based on their gender. The study was conducted at one of the public preschools in Yenimahalle/Ankara with 48 five-year old children from two classes. The first group of students was the experimental group and they were instructed using English talking toys as a teaching material. On the other hand, the other class was the control group and was instructed using flashcards. The target vocabulary for this study, which was incorporated into a Vocabulary Checklist Test, was developed after a close scrutiny of the relevant literature (i.e. vocabulary learning in young learners and examination of the theme-related curriculum employed in the chosen preschool. To assess preschoolers' learning of target words in English, a new Vocabulary Checklist Test was developed by the researcher. The results of a series of t-tests showed that the class instructed with English talking toys performed better on both receptive and expressive/productive vocabulary. The results also indicated that there was not any significant difference between males and females in terms of the effect of English talking toys on preschool children's vocabulary learning. The findings suggest that English talking toys are not only used for entertainment and recreational purposes, they can also be used as teaching material particularly when it comes to teaching basic English vocabulary. The current study contributed to areas such as early childhood education, foreign/second language learning, foreign language testing and evaluation.

    2015-07-01

    Full Text Available The central theme in this paper is the problem of shifting from natural language descriptions, as in traditional dictionaries and thesauri, to working IT (Information Technology systems that support people carrying out their administrative tasks. An explicit description of the specific language used in an organization is necessary to guarantee properly working IT systems and a healthy flow of information. Traditionally, there are different ways of capturing such a vocabulary. Different options are considered, arguing that the general form of a thesaurus offers the optimal solution for a broad range of cases. Various requirements for such a thesaurus are examined. A real world example is discussed in some detail. Finally, the paper examines how modern Web technology can help optimizing the creation, management and use of enterprise thesauri. Using these technologies, the enterprise thesaurus can take up new roles in managing the information household of an organization.

    Most studies in adults with developmental dyslexia have focused on identifying the deficits responsible for their persistent reading difficulties, but little is known on how these readers manage the intensive exposure to written language required to obtain a university degree. The main objective of this study was to identify certain skills, and specifically vocabulary skills, that French university students with dyslexia have developed and that may contribute to their literacy skills. We tested 20 university students with dyslexia and 20 normal readers (matched on chronological age, gender, nonverbal IQ, and level of education) in reading, phonological, vocabulary breadth (number of known words), and vocabulary depth (accuracy and precision) tasks. In comparing vocabulary measures, we used both Rasch model and single case study methodologies. Results on reading and phonological tasks confirmed the persistence of deficits in written word recognition and phonological skills. However, using the Rasch model we found that the two groups performed at the same level in the vocabulary breadth task, whereas dyslexics systematically outperformed their chronological age controls in the vocabulary depth task. These results are supplemented by multiple case studies. The vocabulary skills of French university students with dyslexia are well developed. Possible interpretations of these results are discussed.

  6. Why and How EFL Students Learn Vocabulary in Parliamentary Debate Class

    Directory of Open Access Journals (Sweden)

    Eunice M. Aclan

    2015-02-01

    Full Text Available Vocabulary, the backbone of any language including English, is foundational for listening, speaking, reading and writing. These four macro-skills are necessary not only in gaining knowledge as English is the language to access major information sources particularly the World Wide Web but also in the demanding globalized workplace. Vocabulary is seen to be learned better when it is contextualized thus language teachers should design communicative activities such as debate. However, debate, being more known as a competitive rather than a classroom activity worldwide, has not been explored yet for its potential to develop vocabulary among EFL/ESL students although it has been identified for its power in developing communication skills in general as well as critical thinking and other soft skills. Thus, this qualitative study was conducted to explore why and how EFL students learn vocabulary in classroom debate. The data were gathered through end-of-course evaluation and focus group interview with seven participants from the Middle East, African and ASEAN countries. The findings show that students learned vocabulary due to debate’s interactive nature requiring contextualized and meaningful language use from preparation to actual debate. EFL students described how they learned vocabulary through debate which has implications for SLA and language teaching.   Keywords: Noticing hypothesis, Comprehensible input, Incomprehensible input, Vocabulary building strategies

  7. WORD ORIGIN HELPS EXPAND LEARNERS’ VOCABULARY A VOCABULARY TEACHING APPROACH

    Directory of Open Access Journals (Sweden)

    2012-12-01

    Full Text Available Word origin (motivation deals with the connection between name and sense, explaining how a word originated. With the knowledge of how words are originated, learners can grasp a word easier and thus expand their vocabulary more quickly. The introduction to word origin (motivation by teachers can also help the learners gain interest in the process of learning and learn more about the cultural and historical background of the English-speaking countries. This paper tries to clarify this method of teaching from four aspects: onomatopoeia, word formation, cultural and historical background and cognitive linguistics.

    Full text of publication follows: The ITER activities are fully devoted toward its construction. In accordance with the ITER integrated project schedule, the procurement specifications for the manufacturing of the Vacuum Vessel should be prepared by March 2008 and the procurement specifications for the in-vessel components (first wall/blanket, divertor) by 2009. To update the design, considering design and technology evolution, the ITER Design Review has been launched. Among the various topics being discussed are the important issues related to selection of materials, material procurement, and assessment of performance during operation. The main requirements related to materials for the vacuum vessel and the in-vessel components are summarized in the paper. The specific licensing requirements are to be followed for structural materials of pressure and nuclear pressure equipment components for construction of ITER. In addition, the procurements in ITER will be done mostly 'in-kind' and it is assumed that materials for these components will be produced by different Parties. However, in accordance with the regulatory requirements and quality requirements for operation, common specifications and the general rules to fulfill these requirements are to be adopted. For some ITER components (e.g. first wall, divertor high heat flux components), the ultimate qualification of the joining technologies (Be/Cu, SS/Cu, CFC/Cu, W/Cu) is under final evaluation. Successful accomplishment of the qualification program will allow to proceed with procurements of the components for ITER. The criteria for acceptance of these components and materials after manufacturing are described and the main results will be reported. Additional materials issues, which come from the on-going manufacturing R and D program, will be also described. Finally, further materials activity during the construction phase, needs for final qualification and acceptance of materials are discussed. (authors)

    2010-04-01

    Full Text Available The relationship between meanings of words and their sound shapes is to a large extent arbitrary, but it is well known that languages exhibit sound symbolism effects violating arbitrariness. Evidence for sound symbolism is typically anecdotal, however. Here we present a systematic approach. Using a selection of basic vocabulary in nearly one half of the world’s languages we find commonalities among sound shapes for words referring to same concepts. These are interpreted as due to sound symbolism. Studying the effects of sound symbolism cross-linguistically is of key importance for the understanding of language evolution.

    2015-04-01

    Shared vocabularies are a key element in geoscience data interoperability. Many organizations curate vocabularies, with most Geologic Surveys having a long history of development of lexicons and authority tables. However, their mode of publication is heterogeneous, ranging from PDFs and HTML web pages, spreadsheets and CSV, through various user-interfaces, and public and private APIs. Content maintenance ranges from tightly-governed and externally opaque, through various community processes, all the way to crowd-sourcing ('folksonomies'). Meanwhile, there is an increasing expectation of greater harmonization and vocabulary re-use, which create requirements for standardized content formalization and APIs, along with transparent content maintenance and versioning. We have been trialling a combination of processes and software dealing with vocabulary formalization, registration, search and linking. We use the Simplified Knowledge Organization System (SKOS) to provide a generic interface to content. SKOS is an RDF technology for multi-lingual, hierarchical vocabularies, oriented around 'concepts' denoted by URIs, and thus consistent with Linked Open Data. SKOS may be mixed in with classes and properties from specialized ontologies which provide a more specific interface when required. We have developed a suite of practices and techniques for conversion of content from the source technologies and styles into SKOS, largely based on spreadsheet manipulation before RDF conversion, and SPARQL afterwards. The workflow for each vocabulary must be adapted to match the specific inputs. In linked data applications, two requirements are paramount for user confidence: (i) the URI that denotes a vocabulary item is persistent, and should be dereferenceable indefinitely; (ii) the history and status of the resource denoted by a URI must be available. This is implemented by the Linked Data Registry (LDR), originally developed for the World Meteorological Organization and the UK

    2010-09-20

    Numerous studies have provided evidence that physical activity promotes cortical plasticity in the adult brain and in turn facilitates learning. However, until now, the effect of simultaneous physical activity (e.g. bicycling) on learning performance has not been investigated systematically. The current study aims at clarifying whether simultaneous motor activity influences verbal learning compared to learning in a physically passive situation. Therefore the learning behavior of 12 healthy subjects (4 male, 19-33 years) was monitored over a period of 3 weeks. During that time, behavioral and electrophysiological responses to memorized materials were measured. We found a larger N400 effect and better performance in vocabulary tests when subjects were physically active during the encoding phase. Thus, our data indicate that simultaneous physical activity during vocabulary learning facilitates memorization of new items. Copyright 2010 Elsevier Ireland Ltd. All rights reserved.

    2011-01-01

    The four basic aspects of strengths, ductility, toughness and fatigue strengths can be summarized for overall mechanical properties requirements of materials for nuclear pressure-retaining vessels in ASME-BPV code. These mechanical property indexes involve in the factors of melting, manufacture, delivery conditions, check or recheck for mechanical properties and chemical compositions, etc. and relate to degradation and damage accumulation during the use of materials. This paper specifically accounts for the basic requirements and theoretic basis of mechanical properties for nuclear pressure vessel materials in ASME-BPV code and states the internal mutual relationships among the four aspects of mechanical properties. This paper focuses on putting forward at several problems on mechanical properties of materials that shall be concerned about during design and manufacture for nuclear pressure vessels according to ASME-BPV code.

    1998-01-01

    The U.S. Department of Transportation (DOT) and the U.S. Nuclear Regulatory Commission (NRC) have prepared a comprehensive set of draft guidance for shippers and inspectors to use when applying the newly imposed regulatory requirements for low specific activity (LSA) material and surface contaminated objects (SCOs). These requirements represent significant departures in some areas from the manner in which these materials and objects were regulated by the earlier versions of the regulations. The proper interpretation and application of the regulatory criteria can require a fairly complex set of decisions be made. To assist those trying these regulatory requirements, a detailed set of logic-flow diagrams representing decisions related to multiple factors were prepared and included in the draft report for comment on Categorizing and Transporting Low Specific Activity Materials and Surface Contaminated Objects, (DOT/NRC, 1997). These logic-flow diagrams, as developed, are specific to the U.S. regulations, but were readily adaptable to the IAEA regulations. The diagrams have been modified accordingly and tied directly to specific paragraphs in IAEA Safety Series No. 6. This paper provides the logic-flow diagrams adapted in the IAEA regulations, and demonstrated how these diagrams can be used to assist consignors and inspectors in assessing compliance of shipments with the LSA material and SCO regulatory requirements.

    2016-01-01

    Development and implementation of safety and security requirements for transport of radioactive materials in the Russian Federation are addressed. At the outset it is worth noting that the transport safety requirements implemented are in full accordance with the IAEA's ''Regulations for the Safe Transport of Radioactive Material (2009 Edition)''. However, with respect to security requirements for radioactive material transport in some cases the Russian Federation requirements for nuclear material are more stringent compared to IAEA recommendations. The fundamental principles of safety and security of RM managements, recommended by IAEA documents (publications No. SF-1 and GOV/41/2001) are compared. Its correlation and differences concerning transport matters, the current level and the possibility of harmonization are analysed. In addition a reflection of the general approaches and concrete transport requirements is being evaluated. Problems of compliance assessment, including administrative and state control problems for safety and security provided at internal and international shipments are considered and compared. (author)

    McCormick, T.; Heaven, R.

    2013-12-01

    The British Geological Survey makes extensive use of controlled vocabularies to promote standardisation and interoperability between its databases and other digital information systems. Many of our vocabularies are published and searchable at http://www.bgs.ac.uk/data/vocabularies/home.html/. There is a movement to ';open up' government data in both the US and UK. In the UK this is promoted by data.gov.uk. Some view linked data as the best way to share and connect disparate data, information and knowledge, in order to develop a ';Web of Data'. Linked data facilitate connections between data sets, and lower the barriers to accessing data that must otherwise be discovered and exploited using other methods. Recently there has been a rapid increase in the rate of publication of linked data, this increase currently being estimated at 300% per year. In the past 2 years we have undertaken a pilot study to publish some of our authoritative vocabularies as linked data. This study has focussed primarily on publishing BGS' 1:625 000 scale geologic map data for the UK, supported by development of linked data sets for: Earth materials - based on the BGS Rock Classification Scheme; lithostratigraphy - based on the BGS Lexicon of Named Rock Units; and geochronology - based on the International Commission on Stratigraphy. The BGS linked data sets are published at data.bgs.ac.uk. We have learned a number of lessons about the potential and limitations of linked data and associated technologies. We do not envisage SPARQL endpoints being the primary route for public access to linked data because the user would require technical knowledge of the data structure, and because it can be a security threat. Rather, SPARQL may lie behind a user-friendly API. Federated SPARQL queries that can interrogate distributed data sources are in reality too slow, and in practise the data sets would likely be combined in a single store. The data sets in our pilot study are all reasonably static and we

    Full Text Available This study investigates the effectiveness of using Facebook in enhancing vocabulary knowledge among Community College students. Thirty-three (33 Community College students are exposed to the use of Facebook as an environment of learning and enhancing their English vocabulary. They are given a pre-test and a post-test and the findings indicate that students perform significantly better in the post-test compared to the pre-test. It appears that Facebook could be considered as a supplementary learning environment or learning platform or a learning tool; with meaningful and engaging activities that require students to collaborate, network and functions as a community of practice, particularly for introverted students with low proficiency levels and have low self-esteem.

    Full Text Available One way to assess a person’s communicative competence is through his ability to express his thoughts and ideas in appropriate words and meaningful sentences. Vocabulary learning then is critical to learning a language – be it the first, second or even foreign. However, test results, daily communication and English proficiency exams show that students have difficulty in learning vocabulary. This descriptive-evaluative study assessed the vocabulary learning and the strategies used along context clues, word analysis and dictionary skills of the 100 randomly selected second-year education students of the Sorsogon State College. The study utilized survey-questionnaire, teacher- made test and unstructured interview in gathering data. The study revealed that most of the Bachelor of Elementary Education (BEED and Bachelor of Secondary Education (BSED students oftentimes used strategies in learning vocabulary such as reading books and other materials, looking for clues in sentences and use the dictionary to unlock the unfamiliar words. The students attained nearly competent vocabulary performance along context clues, word analysis and dictionary skills. The context clues and word analysis skills are significantly related to the use of learning strategies when tested at 0.05 level. The developed vocabulary module to enhance the skills of the students can be validated and utilized for instruction.

    2015-01-01

    Full Text Available Abstract: The importance of vocabulary in reading has been discussed extensively in the literature. Researchers claim that vocabulary is essential and has a central role in comprehension.   Development in ICT and easy access to information from the internet necessitate language teachers to have relevant knowledge and skills to utilize pedagogical tools to use authentic online materials for learning purposes.  One of such a tool is the Vocabulary Profiler that can be used to categorize lexical words in a text into different frequency levels: high, low, and academic word list. This paper discusses how to use the Vocabulary Profiler to classify words in a text into the different categories.  The utilization of this tool can significantly alleviate the workload of teachers in selecting vocabulary in  reading text which is conventionally based on teachers’ intuition and perception. The sample text in this paper was selected from VOA website which may not be found in the textbooks currently used at schools. The paper ends with some implication for teaching about vocabulary selection.

    2017-08-01

    The current study attempted to investigate the development of Arabic academic vocabulary knowledge among middle-school Arabic native speakers, taking into account the socioeconomic status of the Arab population in Israel. For this purpose, Arabic academic word list was developed, mapping the required academic words that are needed for adequate coping with informational texts as appearing in the different content areas text-books. Six-hundred Arabic speaking middle school pupils from the different areas in Israel, representing the different Arab subgroups: general Arab community, Druze and Bedouins, have participated in the current study. Two academic vocabulary tests, including receptive and productive academic vocabulary evaluation tests, were administrated to the students across the different age groups (7th, 8th and 9th). The results pointed to no significant difference between 7th and 9th grade in academic vocabulary knowledge. In contrast, significant difference was encountered between the different Arab sub-groups where the lowest scores were noted among the Bedouin sub-group, characterized by the lowest SES. When comparing receptive and productive academic vocabulary knowledge between 7th and 9th grade, the results pointed to improvement in receptive academic knowledge towards the end of middle school but not on the productive knowledge level. In addition, within participants' comparison indicated a gap between the pupils' receptive and productive vocabulary. The results are discussed in relation to the existing scientific literature and to its implication of both research and practice in the domain of Arabic literacy development.

    Ptok, M; Kühn, D; Miller, S

    2014-04-01

    During first language acquisition (L1), children need to gather knowledge about the speech sounds and grammar of their mother tongue. Furthermore, communication skills require an adequate vocabulary. Individual profiles of vocabulary acquisition can vary considerably. However, actively using around 50 words by the age of 24 months is considered a milestone in first language acquisition. This is usually followed by the so-called vocabulary spurt, a rapid increase in lexical knowledge. This article provides an overview of the theories of lexical development and discusses how the acquisition of vocabulary may be explained. A selective literature search was conducted in PubMed and Scopus. Current textbooks were also considered. In order to acquire new words, a child has to identify what the new string of speech sounds refers to. The child has to construct a valid concept of the word and subsequently store both word and concept into long-term memory. Several theories have been put forward to explain lexicon organization, the acquisition of concepts and the mechanisms underlying the so-called fast mapping phenomenon in particular. All of these attempt to explain the phenomenon of lexicon acquisition in terms of a model scheme. In the context of the fast mapping mechanism, constraints and assumptions, cognitive, intentionalist and emergence-based theories are discussed. Knowledge of the different theories of vocabulary acquisition is mandatory to understand the construction of the tests used to assess vocabulary skills in clinical practice and to apply these appropriately.

    The relationship between children's slow vocabulary growth and the family's low socioeconomic status (SES) has been well documented. However, previous studies have often focused on infants or preschoolers and primarily used static measures of vocabulary at multiple time points. To date, there is no research investigating whether SES predicts a child's word learning abilities in grade school and, if so, what mediates this relationship. In this study, 68 children aged 8-15 years performed a written word learning from context task that required using the surrounding text to identify the meaning of an unknown word. Results revealed that vocabulary knowledge significantly mediated the relationship between SES (as measured by maternal education) and word learning. This was true despite the fact that the words in the linguistic context surrounding the target word are typically acquired well before 8 years of age. When controlling for vocabulary, word learning from written context was not predicted by differences in reading comprehension, decoding, or working memory. These findings reveal that differences in vocabulary growth between grade school children from low and higher SES homes are likely related to differences in the process of word learning more than knowledge of surrounding words or reading skills. Specifically, children from lower SES homes are not as effective at using known vocabulary to build a robust semantic representation of incoming text to identify the meaning of an unknown word.

    Full Text Available In our modern technological world, Computer-Assisted Language learning (CALL is a new realm towards learning a language in general, and learning L2 vocabulary in particular. It is assumed that the use of multimedia annotations promotes language learners’ vocabulary acquisition. Therefore, this study set out to investigate the effects of different multimedia annotations (still picture annotations, dynamic picture annotations, and written annotations on L2 vocabulary learning. To fulfill this objective, the researchers selected sixty four EFL learners as the participants of this study. The participants were randomly assigned to one of the four groups: a control group that received no annotations and three experimental groups that received:  still picture annotations, dynamic picture annotations, and written annotations. Each participant was required to take a pre-test. A vocabulary post- test was also designed and administered to the participants in order to assess the efficacy of each annotation. First for each group a paired t-test was conducted between their pre and post test scores in order to observe their improvement; then through an ANCOVA test the performance of four groups was compared. The results showed that using multimedia annotations resulted in a significant difference in the participants’ vocabulary learning. Based on the results of the present study, multimedia annotations are suggested as a vocabulary teaching strategy.

    Full Text Available Considering the overall tendency of foreign language learners to use mechanical strategies of rote rehearsal in vocabulary learning and their resistance towards use of 'deep' vocabulary learning strategies, namely contextual guessing, Keyword Method, metacognitive strategy, and semantic mapping, this study intended (a to explore what impact the instruction of these deep strategies, on vocabulary retention of 32 post-intermediate adult EFL Iranian learners, (b to determine how the variable of gender influences the vocabulary retention of students after receiving training in these strategies. To this end, on the basis of a strategy-based model of instruction–CALLA (Chamot & O'Malley, 1994, the experimental group received training in using 'deep' vocabulary learning strategies while the control group received only the common method of vocabulary teaching. After the treatment, following factorial design, the performance of the participants in the teacher-made vocabulary test as posttest was analyzed statistically.  The results indicated higher vocabulary retention for the experimental group, and it was revealed that female students were more receptive to strategy training. This study provides evidence for confirmation of 'depth of processing' hypothesis and the emerging theory about the impact of gender on effective strategy teaching and use, and it recommends incorporation of teaching these 'deep' strategies of vocabulary learning into EFL classrooms.

    2006-01-01

    The international technology roadmap for semiconductors (ITRS) is a joint global effort of the semiconductor industry, the manufacturing equipment and material industry and the research community and consortia to define the future requirements and development of the semiconductor technology for the next 15 years. The ITRS started in 1992 as a US-national roadmap and became an international effort in 1998 with all major five industrial global regions (US, Japan, Taiwan, Korea and Europe) participating in its definition. The outlook in semiconductor manufacturing expects the continuous application of silicon technology for the next 15 years where complementary metal oxide semiconductor (CMOS) based devices will carry the development of the industry at least for one more decade. New device architectures and concepts based on silicon wafer material are being developed to support the development of the IC industry for another one or two decade. The major section of the ITRS contains technical information about frontend processing and interconnects, device structures and memory concepts, lithography and metrology as well as factory integration and environmental issues. This paper will review the material requirements and the expected material innovations for the industry as outlined in the ITRS Version 2005. Materials to be discussed are, for example, high permittivity gate dielectrics, insulating layers with low dielectric constants for interconnects, and capacitor dielectrics for dynamic memories. In addition, the paper will address, for example, new transistor gate materials, new solutions for interconnect systems beyond copper as well as new starting materials for wafer sizes beyond 300 mm. This publication was presented as an invited paper in the Symposium V of the 2006 spring meeting of the European Materials Research Society (E-MRS) in Nice, May 29th

    Data integration act as the preliminary entry point as we enter the era of big data in many scientific domains. However the reusefulness of various dataset has met the hurdle due to different initial of interests of different parties, therefore different vocabularies in describing similar or semantically related concepts. In this scenario it is vital to devise an automatic or semi-supervised algorithm to facilitate the convergence of different vocabularies. The Ocean Data Interoperability Platform (ODIP) seeks to increase data sharing across scientific domains and international boundaries by providing a forum to harmonize diverse regional data systems. ODIP participants from the US include the Rolling Deck to Repository (R2R) program, whose mission is to capture, catalog, and describe the underway/environmental sensor data from US oceanographic research vessels and submit the data to public long-term archives. In an attempt to harmonize these regional data systems, especially vocabularies, R2R recognizes the value of the SeaDataNet vocabularies served by the NERC Vocabulary Server (NVS) hosted at the British Oceanographic Data Centre as a trusted, authoritative source for describing many oceanographic research concepts such as instrumentation. In this work, we make use of the semantic relations in the vocabularies served by NVS to build a Bayesian network and take advantage of the idea of entropy in evaluating the correlation between different concepts and keywords. The performance of the model is evaluated against matching instruments from R2R against the SeaDataNet instrument vocabularies based on calculated confidence scores in the instrument pairings. These pairings with their scores can then be analyzed for assertion growing the interoperability of the R2R vocabulary through its links to the SeaDataNet entities.

    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.

    International Nuclear Information System (INIS)

    Seeman, M.J.

    1987-01-01

    On June 7, 1985, the US Nuclear Regulatory Commission (NRC) published an advance notice of proposed rulemaking (ANPRM) in the Federal Register to address funding for cleanup of accidents and unexpected decontamination by certain materials licensees. The NRC asked for public comment to help them determine whether to amend its regulations to require certain materials and fuel cycle licensees to demonstrate that they possess adequate financial means to pay for cleanup of accidental releases of radioactive materials. If licensees lack adequate financial resources and funds are to available for prompt cleanup, the consequences could be potentially significant for the public, the licencee and the federal government. The purpose of this paper is to explain the purpose and scope of the Commission's proposed regulatory action, as well as describing several accidents that made the Commission consider this action. Additionally, the paper will address other regulatory precedents. Finally, the paper will conclude by generally characterizing the public comments and items of concern raised by commenters

  13. Structural materials requirements for in-vessel components of fusion power plants

    International Nuclear Information System (INIS)

    Schaaf, B. van der

    2000-01-01

    The economic production of fusion energy is determined by principal choices such as using magnetic plasma confinement or generating inertial fusion energy. The first generation power plants will use deuterium and tritium mixtures as fuel, producing large amounts of highly energetic neutrons resulting in radiation damage in materials. In the far future the advanced fuels, 3 He or 11 B, determine power plant designs with less radiation damage than in the first generation. The first generation power plants design must anticipate radiation damage. Solid sacrificing armour or liquid layers could limit component replacements costs to economic levels. There is more than radiation damage resistance to determine the successful application of structural materials. High endurance against cyclic loading is a prominent requirement, both for magnetic and inertial fusion energy power plants. For high efficiency and compactness of the plant, elevated temperature behaviour should be attractive. Safety and environmental requirements demand that materials have low activation potential and little toxic effects under both normal and accident conditions. The long-term contenders for fusion power plant components near the plasma are materials in the range from innovative steels, such as reduced activation ferritic martensitic steels, to highly advanced ceramic composites based on silicon carbide, and chromium alloys. The steels follow an evolutionary path to basic plant efficiencies. The competition on the energy market in the middle of the next century might necessitate the riskier but more rewarding development of SiCSiC composites or chromium alloys

    Full text: High-sensitivity nuclear environmental sampling and analysis techniques have been proven in their ability to verify declared nuclear activities, as well as to assist in the detection of undeclared nuclear activities and facilities. Following the Gulf War, the capability and revealing power of environmental sampling and analysis techniques to support international safeguards was demonstrated and subsequently adopted by the International Atomic Energy Agency (IAEA) as routine safeguards measures in safeguards inspections and verifications. In addition to having been proved useful in international safeguards, environmental sampling and analysis techniques have demonstrated their utility in identifying the origins of 'orphaned' nuclear material, as well as the origin of intercepted smuggled nuclear material. Today, environmental sampling and analysis techniques are now being applied in six broad areas to support nonproliferation, disarmament treaty verification, national and international nuclear security, and environmental stewardship of weapons production activities. Consequently, more and more laboratories around the world are establishing capabilities or expanding capabilities to meet these growing applications, and as such requirements for quality assurance and control are increasing. The six areas are: 1) Nuclear safeguards; 2) Nuclear forensics/illicit trafficking; 3) Ongoing monitoring and verification (OMV); 4) Comprehensive Test Ban Treaty (CTBT); 5) Weapons dismantlement/materials disposition; and 6) Research and development (R and D)/environmental stewardship/safety. Application of environmental sampling and analysis techniques and resources to illicit nuclear material trafficking, while embodying the same basic techniques and resources, does have unique requirements for sample management, handling, protocols, chain of custody, archiving, and data interpretation. These requirements are derived from needs of how data from nuclear forensics

    Directory of Open Access Journals (Sweden)

    Ioana Claudia Horea

    2015-03-01

    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

    This paper examines the responsibility of federal agencies concerned with nuclear materials transportation decisions that come within the scope of the National Environmental Policy Act of 1969 (NEPA) and the requirements established by the Council on Environmental Quality (CEQ). Two of the case histories presented in this paper focus on actions taken by the Nuclear Regulatory Commission (NRC) and the Department of Transportation (DOT). A third case history, in which the limits of environmental impact are judicially redefined, presents an analysis of NEPA application in an NRC licensing action. The decision by the US Supreme Court (April 19, 1983) disallowed psychological stress as a factor to be required in environmental analysis of federal actions. The review by the Supreme Court of environmental impact considerations required under NEPA is clearly transferable to federal actions involving transportation of nuclear materials. Of interest in these examples is the application of NEPA requirements for worst-case analysis and the employment of the rule of reason by a federal agency to determine the limits of its NEPA obligations

    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.

    Full Text Available The purpose of this study is to investigate the relationship between vocabulary knowledge and the use of contextual clues and whether EFL learners who are well-equipped with reading skills are able to comprehend the text despite a low level of vocabulary knowledge. Therefore, the study focused on which vocabulary dimensions help students guess unfamiliar words. The study was carried out at Hatyai University in Thailand. The population of this study consisted of 34 undergraduates who were studying International Business English and had taken a course in reading techniques. The present study was conducted to conceptually validate the roles of breadth and depth of vocabulary knowledge to improve skills by contextual clue. Vocabulary Depth was specially employed to evaluate two dimensions namely Paradigmatic and Syntagmatic. The Schmitt and Clapham Vocabulary Level Test was used to test vocabulary breadth, while the vocabulary depth was implemented by Read’s Vocabulary Depth Test. Reading parts of the TOEFL were adopted for contextual clue items. There were two statistical analysis tools also implemented in this study: paired-sample t-test and bivariate correlation. First, in an attempt to find which vocabulary dimension predominates in guessing word meaning from the text, a paired-sample t-test was utilized to compare the difference of two vocabulary dimensions in reading part: vocabulary depth and contextual clues, and vocabulary breadth and contextual clues. Second, a bivariate correlation was used to find the degree of relationship between vocabulary knowledge and contextual clues. The consequences of this study identified empirical results that 1 there was a positive relationship between contextual clues and vocabulary depth, the reverse is true in vocabulary breadth. Moreover, vocabulary depth is more significantly crucial than breadth to enhance student’s ability to guess words’ meaning from the context.

    A multi-agency workshop was held from 25 to 27 August 2009, at the National Institute of Standards and Technology (NIST), to identify and prioritize the development of radioanalytical Certified Reference Materials (CRMs, generally provided by National Metrology Institutes; Standard Reference Materials, a CRM issued by NIST) for field and laboratory nuclear measurement methods to be used to assess the consequences of a domestic or international nuclear event. Without these CRMs, policy makers concerned with detecting proliferation and trafficking of nuclear materials, attribution and retribution following a nuclear event, and public health consequences of a nuclear event would have difficulty making decisions based on analytical data that would stand up to scientific, public, and judicial scrutiny. The workshop concentrated on three areas: post-incident Improvised Nuclear Device (IND) nuclear forensics, safeguard materials characterization, and consequence management for an IND or a Radiological Dispersion Device detonation scenario. The workshop identified specific CRM requirements to fulfill the needs for these three measurement communities. Of highest priority are: (1) isotope dilution mass spectrometry standards, specifically 233 U, 236 gNp, 244 Pu, and 243 Am, used for quantitative analysis of the respective elements that are in critically short supply and in urgent need of replenishment and certification; (2) CRMs that are urgently needed for post-detonation debris analysis of actinides and fission fragments, and (3) CRMs used for destructive and nondestructive analyses for safeguards measurements, and radioisotopes of interest in environmental matrices.

    1978-01-01

    A Purex-based nuclear fuel reprocessing plant has been studied for possible incorporation of near-real-time accounting to supplement conventional accounting procedures. Near-real-time accounting of special nuclear materials relies on in-line or at-line flow measurements and plutonium assay of product and waste streams, complemented by conventional analytical chemistry for daily instrument calibrations. In-line alpha monitors could be used for waste stream measurements of plutonium, even in the presence of high beta-gamma fluxes from fission products. X-ray absorption edge densitometry using either K- or L-absorption edges could be used for plutonium concentration measurements in main product streams. Some problem areas identified in waste stream measurements include measurements of leached hulls and of centrifuge sludge. Conventional analytical chemical methods for measuring plutonium in weapons grade material can be modified for reprocessed plutonium. Analytical techniques requiring special precautions will be reviewed

    Natural laminar flow is one of the challenging aims of the current aerospace research. Main reasons for the aerodynamic transition from laminar into turbulent flow focusing on the airfoil-structure is the aerodynamic shape and the surface roughness. The Institute of Composite Structures and Adaptive Systems at the German Aerospace Center in Braunschweig works on the optimization of the aerodynamic-loaded structure of future aircrafts in order to increase their efficiency. Providing wing structures suited for natural laminar flow is a step towards this goal. Regarding natural laminar flow, the structural design of the leading edge of a wing is of special interest. An approach for a gap-less leading edge was developed to provide a gap- and step-less high quality surface suited for natural laminar flow and to reduce slat noise. In a national project the first generation of the 3D full scale demonstrator was successfully tested in 2010. The prototype consists of several new technologies, opening up the issue of matching the long and challenging list of airworthiness requirements simultaneously. Therefore the developed composite structure was intensively tested for further modifications according to meet requirements for abrasion, impact and deicing basically. The former presented structure consists completely of glass-fiber-prepreg (GFRP-prepreg). New functions required the addition of a new material-mix, which has to fit into the manufacturing-chain of the composite structure. In addition the hybrid composites have to withstand high loadings, high bending-induced strains (1%) and environmentally influenced aging. Moreover hot-wet cycling tests are carried out for the basic GFRP-structure in order to simulate the long term behavior of the material under extrem conditions. The presented paper shows results of four-points-bending-tests of the most critical section of the morphing leading edge device. Different composite-hybrids are built up and processed.

    1995-01-01

    Although a considerable volume of valuable data on the behaviour of tritium in beryllium and carbon-based armours exposed to hydrogenic fusion plasmas has been compiled over the past years both from operation of present-day tokamaks and from laboratory simulations, knowledge is far from complete and tritium inventory predictions for these materials remain highly uncertain. In this paper we elucidate the main mechanisms responsible for tritium trapping and release in next-step D-T tokamaks, as well as the applicability of some of the presently known data bases for design purposes. Owing to their strong anticipated implications on tritium uptake and release, attention is focused mainly on the interaction of tritium with neutron damage induced defects, on tritium codeposition with eroded carbon and on the effects of oxide and surface contaminants. Some preliminary quantitative estimates are presented based on most recent experimental findings and latest modelling developments as well. The influence of important working conditions such as target temperature, loading particle fluxes, erosion and redeposition rates, as well as material characteristics such as the type of morphology of the protection material (i.e. amorphous plasma-sprayed beryllium vs. solid forms), and design dependent parameters are discussed in this paper. Remaining issues which require additional effort are identified. (orig.)

  3. Inkjet Printing of Functional and Structural Materials: Fluid Property Requirements, Feature Stability, and Resolution

    Science.gov (United States)

    Derby, Brian

    2010-08-01

    Inkjet printing is viewed as a versatile manufacturing tool for applications in materials fabrication in addition to its traditional role in graphics output and marking. The unifying feature in all these applications is the dispensing and precise positioning of very small volumes of fluid (1-100 picoliters) on a substrate before transformation to a solid. The application of inkjet printing to the fabrication of structures for structural or functional materials applications requires an understanding as to how the physical processes that operate during inkjet printing interact with the properties of the fluid precursors used. Here we review the current state of understanding of the mechanisms of drop formation and how this defines the fluid properties that are required for a given liquid to be printable. The interactions between individual drops and the substrate as well as between adjacent drops are important in defining the resolution and accuracy of printed objects. Pattern resolution is limited by the extent to which a liquid drop spreads on a substrate and how spreading changes with the overlap of adjacent drops to form continuous features. There are clearly defined upper and lower bounds to the width of a printed continuous line, which can be defined in terms of materials and process variables. Finer-resolution features can be achieved through appropriate patterning and structuring of the substrate prior to printing, which is essential if polymeric semiconducting devices are to be fabricated. Low advancing and receding contact angles promote printed line stability but are also more prone to solute segregation or “coffee staining” on drying.

  4. Vocabulary knowledge, phonological representations and phonological sensitivity in Spanish-speaking low-and middle-SES preschoolers

    Directory of Open Access Journals (Sweden)

    Beatriz Diuk

    2013-08-01

    Full Text Available The aim of this study was to examine the relationships among vocabulary knowledge, phonological representations and phonological sensitivity in 80 Spanish-speaking preschool children from middle- and low-SES families. Significant social class differences were obtained on all tasks except syllable matching. Regression analyses were carried out to test the predictive power of vocabulary knowledge and accuracy of phonological representations on the phonological sensitivity measures. Receptive vocabulary predicted rhyme identification. Syllable matching was predicted by a task tapping accuracy of phonological representations. The fact that rhyme identification was predicted by vocabulary knowledge but syllable matching was predicted by a measure tapping accuracy of phonological representations in both groups suggests that early lexical development sets the stage for the development of the lower levels of phonological sensitivity but identification of smaller units requires more accurate and segmented phonological representations.

    The objective of this project is to examine safety aspects of candidate hydrogen storage materials and systems being developed in the DOE Hydrogen Program. As a result of this effort, the general DOE safety target will be given useful meaning by establishing a link between the characteristics of new storage materials and the satisfaction of safety criteria. This will be accomplished through the development and application of formal risk analysis methods, standardized materials testing, chemical reactivity characterization, novel risk mitigation approaches and subscale system demonstration. The project also will collaborate with other DOE and international activities in materials based hydrogen storage safety to provide a larger, highly coordinated effort.

    Full Text Available An increasing body of research evidence is showing the advantages of using certain skills and behaviours called language learning strategies in general and vocabulary learning strategies (VLSs in particular in the process of L2 acquisition. University students who require reading English texts in their fields of study have to expand their vocabulary knowledge in a much more efficient way than ordinary ESL/EFL learners.  And ELT course books are a good place to incorporate learner training in this regard. The purpose of this study is to see how vocabulary learning strategies are treated in both the book designer's claims section and the exercises of English for Specific Purposes (ESP course books for students of medicine and para-medicine on the one hand and English for General Purposes (EGP course book used commonly by these students in Isfahan University of Medical Sciences, Isfahan, Iran on the other. In other words, the specified course books were analyzed based on the insights gained from VLS research to gauge the extent to which they have incorporated VLSs and training in using them. These books were published under the supervision of the center for studying and compiling university books in humanities (SAMT. Based on the review of the relevant literature, three key strategies were identified and an analytic framework was devised. The framework was then applied to the course books. It was found that the treatments in the specified course books were deemed unlikely to improve students’ abilities with these important skills and strategies.

    Children with unilateral cochlear implants (CIs) may have delayed vocabulary development for an extended period after implantation. Bilateral cochlear implantation is reported to be associated with improved sound localization and enhanced speech perception in noise. This study proposed that bilateral implantation might also promote early vocabulary development. Knowledge regarding vocabulary growth and composition in children with bilateral CIs and factors associated with it may lead to improvements in the content of early speech and language intervention and family counselling. To analyse the growth of early vocabulary and its composition during the first year after CI activation and to investigate factors associated with vocabulary growth. The participants were 20 children with bilateral CIs (12 boys; eight girls; mean age at CI activation = 12.9 months). Vocabulary size was assessed with the Finnish version of the MacArthur Communicative Development Inventories (CDI) Infant Form and compared with normative data. Vocabulary composition was analysed in relation to vocabulary size. Growth curve modelling was implemented using a linear mixed model to analyse the effects of the following variables on early vocabulary growth: time, gender, maternal education, residual hearing with hearing aids, age at first hearing aid fitting and age at CI activation. Despite clear vocabulary growth over time, children with bilateral CIs lagged behind their age norms in receptive vocabulary during the first 12 months after CI activation. In expressive vocabulary, 35% of the children were able to catch up with their age norms, but 55% of the children lagged behind them. In receptive and expressive vocabularies of 1-20 words, analysis of different semantic categories indicated that social terms constituted the highest proportion. Nouns constituted the highest proportion in vocabularies of 101-400 words. The proportion of verbs remained below 20% and the proportion of function words and

    A technical, defensible basis for the number and placement of air sampling instruments in a radioactive materials handling facility was developed. Historical air sampling data, process and physicochemical knowledge, qualitative smoke dispersion studies with video documentation, and quantitative trace gas dispersion studies were used to develop a strategy for number and placement of air samplers. These approaches can be used in other facilities to provide a basis for operational decisions. The requirements for retrospective sampling, personal sampling, and real-time monitoring are included. Other relevant operational decisions include selecting the numbers, placement, and appropriate sampling rates for instruments, identifying areas of stagnation or recirculation, and determining the adequacy and efficiency of any sampling transport lines. Justification is presented for using a graded approach to characterizing the workplace and determining air sampling and monitoring needs

    Heming, Thomas A; Nandagopal, Shobha

    2012-11-01

    Medical education requires student comprehension of both technical (scientific/medical) and non-technical (general) vocabulary. Our experience with "English as a second language" (ESL) Arab students suggested they often have problems comprehending scientific statements because of weaknesses in their understanding of non-scientific vocabulary. This study aimed to determine whether ESL students have difficulties with general vocabulary that could hinder their understanding of scientific/medical texts. A survey containing English text was given to ESL students in the premedical years of an English-medium medical school in an Arabic country. The survey consisted of sample questions from the Medical College Admission Test (USA). Students were instructed to identify all unknown words in the text. ESL students commenced premedical studies with substantial deficiencies in English vocabulary. Students from English-medium secondary schools had a selective deficiency in scientific/medical terminology which disappeared with time. Students from Arabic-medium secondary schools had equal difficulty with general and scientific/medical vocabulary. Deficiencies in both areas diminished with time but remained even after three years of English-medium higher education. Typically, when teaching technical subjects to ESL students, attention is focused on subject-unique vocabulary and associated modifiers. This study highlights that ESL students also face difficulties with the general vocabulary used to construct statements employing technical words. Such students would benefit from increases in general vocabulary knowledge.

    These Schedules have been prepared as a companion document to the 1985 Edition of the Transport Regulations (Safety Series No. 6). As presented here, the Schedules also reflect the corrections and changes implemented by the 1986 Supplement to the Regulations for the Safe Transport of Radioactive Material. Direct cross-referencing to the paragraphs, tables and figures in the Regulations is made, and the use of both the International System of Units (SI) and the formerly accepted, traditional units is continued. In many cases, due to rounding off the numbers, the two values for a given parameter for the two units may differ somewhat. To move toward international use of SI units and to avoid inconsistencies, the values for the SI units are controlling in all cases. These Schedules are provided only as an aid to users of the Regulations and the provisions of the Regulations take precedence over the Schedules. These Schedules also serve as a generic model of the Schedules which are part of modal international regulatory documents, such as the International Maritime Dangerous Goods (IMDG) Code of the International Maritime Organization (IMO), the European Agreement Concerning the International Carriage of Dangerous Goods by Road (ADR) and the International Convention Concerning the Carriage of Dangerous Goods by Rail (CIM/RID). For regulatory purposes, reference shall be made to the detailed provisions of the Regulations specified in Safety Series No. 6. The Schedules do not reproduce the provisions of the Regulations in detail nor do they contain any additional requirements. They merely provide a summary of the main provisions for each specified type of radioactive material, references being provided to the relevant detailed provisions of the Regulations to enable these to be consulted where necessary. A table summarizing package, shipment approval, and notification requirements of the Regulations is provided

  11. Comparing the efficacy of digital flashcards versus paper flashcards to improve receptive and productive L2 vocabulary

    Directory of Open Access Journals (Sweden)

    Gilbert Dizon

    2017-06-01

    Full Text Available Several researchers have compared the efficacy of digital flashcards (DFs versus paper flashcards (PFs to improve L2 vocabulary and have concluded that using DFs is more effective (Azabdaftari & Mozaheb, 2012; Başoğlu & Akdemir, 2010; Kiliçkaya & Krajka, 2010. However, these studies did not utilize vocabulary learning strategies (VLSs as a way to support the vocabulary development of those using PFs. This is significant because DFs often offer a range of features to promote vocabulary development, whereas PFs are much more basic; thus, learners who study via paper materials are at a disadvantage compared with those who use DFs. Given the success that VLSs have had in fostering L2 vocabulary enhancement (e.g., Mizumoto & Takeuchi, 2009, their incorporation could have influenced the previous studies. Therefore, one of the primary aims of this study was to find if there were significant differences in receptive and productive L2 vocabulary improvements between students who used PFs in conjunction with 3 VLSs – dropping, association, and oral rehearsal – and those who used the DF tools Quizlet and Cram. Additionally, the researchers examined the learners’ opinions to see if there was a preference for either study method. A total of 52 EFL students at two Japanese universities participated in the 12-week study. Pre- and post-tests were administered to measure the vocabulary gains in the PF group (n = 26 and the DF group (n = 26. Results from a paired t-test revealed that both groups made significant improvements in receptive and productive vocabulary. However, the difference between the gains was not significant, which contrasts with past comparison studies of DFs and PFs and highlights the importance of VLSs. A 10-item survey with closed and Likert-scale questions was also administered to determine the participants’ opinions towards the study methods. Higher levels of agreement were found in the experimental group, indicating that the

    Composites containing thin Shape Memory Alloy (SMA) wires show great potential as materials able to adapt their shape, thermal behavior or vibrational properties to external stimuli. The functional properties of SMA-composites are directly related to the constraining effect of the matrix on the reversible martensitic transformation of the embedded pre-strained SMA wires. The present work reports results of a concerted European effort towards a fundamental understanding of the manufacturing and design of SMA composites. This first part investigates the transformational behavior of constrained SMA wires and its translation into functional properties of SMA composites. Thermodynamic and thermomechanical experiments were performed on SMA wires. A model was developed to simulate the thermomechanical behavior of the wires. From the screening of potential wires it was concluded that NiTiCu, as well as R-phase NiTi appeared as best candidates. Requirements for the host composite materials were surveyed. A Kevlar-epoxy system was chosen. Finally, the quality of the SMA wire-resin interface was assessed by two different techniques. These indicated that a thin oxide layer seems to provide the best interfacial strength. A temperature window in which SMA composites can be safely used was also defined. The manufacturing and properties of the SMA composites will be discussed in Part II.

  13. Transportation of hydrogen in pipelines: interaction of NDE and material requirements

    International Nuclear Information System (INIS)

    Thompson, R.B.; Thompson, A.W.; Thompson, D.O.

    1976-01-01

    The role of nondestructive evaluation (NDE) of materials used in H pipelines and storage facilities is examined. NDE techniques are available which detect critical flaws in today's natural gas lines, and which should have some success in hydrogen lines made of resistant materials. However, the critical flaws in a hydrogen line which is built of a steel whose toughness is significantly reduced in hydrogen, or which contains low-toughness defects such as weld hard spots, would be extremely difficult to detect with today's instrumentation. That instrumentation is designed to test efficiently long lengths of line with minimum disruption of service. Technology is available that would be capable of the more detailed inspection required for the smaller defects. However, the equipment might be expensive and time-consuming to operate, and these costs must be included in the overall assessment of a system using existing lines without embrittlement protection. In addition, it is evident that strong motivation exists to construct new facilities from steels with improved resistance to hydrogen

  16. European DEMO divertor target: Operational requirements and material-design interface

    Directory of Open Access Journals (Sweden)

    J.H. You

    2016-12-01

    Full Text Available Recently, an integrated program of conceptual design activities for the European DEMO reactor was launched in the framework of the EUROfusion Consortium, where reliable power handling capability was identified as one of the most critical scientific as well as technological challenges for a DEMO reactor. The divertor is the key in-vessel plasma-facing component being in charge of power exhaust and removal of impurity particles. The DEMO divertor target will have to withstand extreme thermal loads where the local peak heat flux is expected to reach up to 20 MW/m2 during slow transient events in DEMO. To assure sufficient heat removal capability of the divertor target against normal and transient operational scenarios under expected cumulative neutron dose of up to 13 dpa is one of the fundamental engineering challenges imposed on target design. To develop the design of the DEMO divertor and related technologies, an R&D work package ‘Divertor’ has been set up in this consortium. The subproject ‘Target Development’ is devoted to the development of the conceptual design and the core technologies of the plasma-facing target. Devising and implementing novel structural heat sink materials (e.g. W/Cu composites to advanced target design concepts is one of the major objectives of this subproject. In this paper, the underlying design requirements imposed by the envisaged power exhaust goal and the prominent material-design interface issues are discussed. In addition, the candidate design concepts being currently considered are presented together with the related material issues. Finally, the first results achieved so far are presented.

    In January 1990, the Nuclear Regulatory Commission (NRC) proposed amendments to 10 CFR Part 35 that would require medical licensees using byproduct material to establish and implement a basic quality assurance program. A 60-day real-world trial of the proposed rules was initiated to obtain information beyond that generally found through standard public comment procedures. Volunteers from randomly selected institutions had opportunities to review the details of the proposed regulations and to implement these rules on a daily basis during the trial. The participating institutions were then asked to evaluate the proposed regulations based on their personal experiences. The pilot project sought to determine whether medical institutions could develop written quality assurance programs that would meet the eight performance-based objectives of proposed Section 35.35. In addition, the NRC wanted to learn from these volunteers if they had any recommendations on how the rule could be revised to minimized its cost and to clarify its objectives without decreasing its effectiveness. It was found that licensees could develop acceptable QA programs under a performance-based approach, that most licensee programs did meet the proposed objectives, and that most written QA plans would require consultations with NRC or Agreement State personnel before they would fully meet all objectives of proposed Section 35.35. This report describes the overall pilot program. The methodology used to select and assemble the group of participating licensees is presented. The various workshops and evaluation questionnaires are discussed, and detailed findings are presented. 7 refs.

  19. Routine inspection effort required for verification of a nuclear material production cutoff convention

    International Nuclear Information System (INIS)

    Fishbone, L.G.; Sanborn, J.

    1994-12-01

    Preliminary estimates of the inspection effort to verify a Nuclear Material Cutoff Convention are presented. The estimates are based on (1) a database of about 650 facilities a total of eight states, i.e., the five nuclear-weapons states and three ''threshold'' states; (2) typical figures for inspection requirements for specific facility types derived from IAEA experience, where applicable; and (3) alternative estimates of inspection effort in cutoff options where full IAEA safeguards are not stipulated. Considerable uncertainty must be attached to the effort estimates. About 50--60% of the effort for each option is attributable to 16 large-scale reprocessing plants assumed to be in operation in the eight states; it is likely that some of these will be shut down by the time the convention enters into force. Another important question involving about one third of the overall effort is whether Euratom inspections in France and the U.K. could obviate the need for full-scale IAEA inspections at these facilities. Finally, the database does not yet contain many small-scale and military-related facilities. The results are therefore not presented as predictions but as the consequences of alternative assumptions. Despite the preliminary nature of the estimates, it is clear that a broad application of NPT-like safeguards to the eight states would require dramatic increases in the IAEA's safeguards budget. It is also clear that the major component of the increased inspection effort would occur at large reprocessing plants (and associated plutonium facilities). Therefore, significantly bounding the increased effort requires a limitation on the inspection effort in these facility types

  20. THE EFFECT OF USING FLASH CARD AND PICTURE STORY IN VOCABULARY MASTERY TO THE SEVENTH GRADER OF SMP PGRI 1 MARGATIGA

    Khoirul Hidayat -

    2017-05-01

    Full Text Available Based on the content standard, junior high school students are hoped to master vocabulary about 1000 words, so they can understand the conversation. But it fact, most of the students in junior high school do not master vocabulary well. So, the teacher should be able to choose a good media to help students to increase their vocabulary. In this case, flash card with picture story is two of media that can be used to transfer vocabulary material for the students.   The objective of this research is to find the significant differences of using flash card with picture story in vocabulary, and to find which medium is more effective to use as media in vocabulary. This research was true experiment design. Pre test and post test were use to collect the data. There are two problems of the study, (1 are there any significant differences between flash card with picture story in vocabulary mastery for the seventh grade students in SMP PGRI 2 Margatiga academic years 2013/2014?, (2 which one is more effective media in vocabulary learning process, is it flash card or picture story at seventh grade of SMP PGRI 2 Margatiga, academic years 2013/2014?. As a source of data, the researcher utilized flash card with picture story to teach vocabulary for the students. The media help students to learn vocabulary easier and more interesting to understand the subject, so their vocabulary would increase.   The result of the research, it was found that the mean score of picture story in pre test is 53,86, in treatment is 81, and in post test 85,33. Meanwhile the mean score of the flash card media in pre test 59,33, in treatment is 73,5, and in post test is 80,66. It means that the student’s vocabulary has increased, and there is significant difference of using picture story and flash card in vocabulary instruction, and picture story was more effective to use in vocabulary instruction.

  3. Conceptual design of a system for nuclear material control in a research centre according to the IAEA safeguards requirements

    International Nuclear Information System (INIS)

    Bueker, H.; Kotte, U.; Stein, G.

    1976-01-01

    In comparison with other facilities handling nuclear material, a nuclear research centre is characterized by a wider spectrum of operations. This requires a number of installations within the centre such as research reactors, critical assemblies, research institutes and central departments, operating, in general, independently of each other. Nuclear material is stored and processed in small quantities and in different chemical and physical configurations within prescribed license areas. The conceptual design of a new system for nuclear material control in a research centre has to consider the operator's and IAEA's safeguards requirements. Using the example of the Juelich Nuclear Research Centre in the Federal Republic of Germany, these requirements are being examined in conjunction with the specified peculiarities of a nuclear research centre. Following this, a division of the research centre into material balance areas and key measurement points is being proposed, based on the existing facilities and licence areas. The essential characteristic of the concept is a far-reaching displayability of the inventory and flow of nuclear material. The availability of information is based on differentiated material accountancy in conjunction with adequate measurement of nuclear material data. For data processing and generation of data, a computerized record and report system is to be provided as well as a central measurement system. The design of an integrated accountancy system with a central computer and remote terminals is described; various measuring appliances, now being developed or tested, for the non-destructive assay of nuclear material are specified. The functions of a central department for nuclear material management for operating these systems are discussed and the planned verification of nuclear material in the different material balance areas illustrated. On applying the measures described in this paper, the conceptual design of a system for nuclear material

    The IAEA Regulations for the Safe Transport of Radioactive Material specify a range of package requirements that are dependent upon the activity and properties of the radioactive material being transported. For example, Type A packages can be used for the transport of material with an activity of up to one A1 of special form material and one A2 of other material. The A1 and A2 values are determined for over 350 radionuclides using the Q system in the advisory material. This system models the following pathways in the event of a severe accident: External photon dose; External beta dose; Inhalation dose; Skin and ingestion dose due to contamination transfer; Submersion dose. Industrial packages can be used for the transport of low specific activity (LSA) material and surface contaminated objects (SCO) and the particular requirements for these types of materials are derived from a simplistic radiological model that is often referred to as the 10 mg inhalation model. This is because it is based on the assumption that, in a dusty environment, an individual would inhale no more than 10 mg in such a situation, although there is limited reliable information to justify this assumption. Furthermore, there are deficiencies in the specification of some of the material requirements for LSA/SCO material in the IAEA Transport Regulations. Consequently, this can cause some difficulties for operators in complying with the regulations and to competent authorities in their compliance assurance role. Particular areas of difficulty include: It can be difficult to distinguish between LSA-type material and SCO-type; It is difficult to distinguish surface contamination from activity within the object, and between fixed and nonfixed contamination; In order to demonstrate compliance with SCO requirements, measurements of both accessible and nonaccessible contamination are required, although it is not clear how compliance with the inaccessible contamination limit can be measured if it cannot

  5. Operational Demands of AAC Mobile Technology Applications on Programming Vocabulary and Engagement During Professional and Child Interactions.

    Typically, the vocabulary in augmentative and alternative communication (AAC) technologies is pre-programmed by manufacturers or by parents and professionals outside of daily interactions. Because vocabulary needs are difficult to predict, young children who use aided AAC often do not have access to vocabulary concepts as the need and interest arises in their daily interactions, limiting their vocabulary acquisition and use. Ideally, parents and professionals would be able to add vocabulary to AAC technologies "just-in-time" as required during daily interactions. This study compared the effects of two AAC applications for mobile technologies: GoTalk Now (which required more programming steps) and EasyVSD (which required fewer programming steps) on the number of visual scene displays (VSDs) and hotspots created in 10-min interactions between eight professionals and preschool-aged children with typical development. The results indicated that, although all of the professionals were able to create VSDs and add vocabulary during interactions with the children, they created more VSDs and hotspots with the app with fewer programming steps than with the one with more steps, and child engagement and programming participation levels were high with both apps, but higher levels for both variables were observed with the app with fewer programming steps than with the one with more steps. These results suggest that apps with fewer programming steps may reduce operational demands and better support professionals to (a) respond to the child's input, (b) use just-in-time programming during interactions, (c) provide access to more vocabulary, and (d) increase participation.

  9. Use of standard vocabulary services in validation of water resources data

    2010-05-01

    Ontology repositories are increasingly being exposed through vocabulary and concept services. Primarily this is in support of resource discovery. Thesaurus functionality and even more sophisticated reasoning offers the possibility of overcoming the limitations of simple text-matching and tagging which is the basis of most search. However, controlled vocabularies have other important roles in distributed systems: in particular in constraining content validity. A national water information system established by the Australian Bureau of Meterorology ('the Bureau') has deployed a system for ingestion of data from multiple providers. This uses a http interface onto separately maintained vocabulary services as part of the quality assurance chain. With over 200 data providers potentially transferring data to the Bureau, a standard XML-based Water Data Transfer Format (WDTF) was developed for receipt of data into an integrated national water information system. The WDTF schema was built upon standards from the Open Geospatial Consortium (OGC). The structure and syntax specified by a W3C XML Schema is complemented by additional constraints described using Schematron. These implement important content requirements and business rules including: • Restricted cardinality: where optional elements and attributes inherited from the base standards become mandatory in the application, or repeatable elements or attributes are limited to one or omitted. For example, the sampledFeature element from O&M is optional but is mandatory for a samplingPoint element in WDTF. • Vocabulary checking: WDTF data use seventeen vocabularies or code lists derived from Regulations under the Commonwealth Water Act 2007. Examples of codelists are the Australian Water Regulations list, observed property vocabulary, and units of measures. • Contextual constraints: in many places, the permissible value is dependent on the value of another field. For example, within observations the unit of measure

    Full Text Available This quasi-experimental study examined the effects of different glossing conditions on English as a foreign language (EFL learners’ vocabulary recall. To this end, five glossing conditions were adopted (i.e., inference-gloss-gloss, gloss-retrieval-gloss, inference-gloss-retrieval-gloss, gloss-retrieval-gloss-retrieval, and full glossing. The participants were 140 MA students of Teaching English as a Foreign Language (TEFL. They were randomly assigned to one glossing condition to read an English reading passage. Five target words were glossed in different glossing conditions within a reading passage. To ensure the participants’ attention focused on the reading material, the participants were told that a multiple-choice reading comprehension test would be administrated. Afterward, two vocabulary tests (i.e., form recall and meaning recall were conducted. The results of one-way MANOVAs and the post hoc Scheffé tests revealed that the full glossing condition group did significantly better than other glossing groups in vocabulary form recall, whereas the gloss-retrieval-gloss-retrieval condition group outperformed other four groups in vocabulary meaning recall.

Twenty-six second-semester learners of Russian participated in this study. Group one (N = 8 saw video with audio and captions (VAC; group two (N = 9 saw video with audio (VA; group three (N = 9 saw video with captions (VC. All participants completed written and aural vocabulary tests and a final questionnaire.The results indicate that groups with captions (VAC and VC scored higher on written than on aural recognition of word forms, while the reverse applied to the VA group. The VAC group learned more word meanings than the VA group. Results from the questionnaire suggest that learners paid most attention to captions, followed by video and audio, and acquired most words by associating them with visual images. Pedagogical implications of this study are that captioned video tends to aid recognition of written word forms and the learning of word meaning, while non-captioned video tends to improve listening comprehension as it facilitates recognition of aural word forms.

  3. Incidental Vocabulary Learning in Second Language Acquisition: A Literature Review

    Directory of Open Access Journals (Sweden)

    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.

  4. Peculiarities in covering the requirements for seed material of sorghum crops

    2017-12-01

    Full Text Available Purpose. To assess the demand for sorghum seed material and sufficiency of domestic seeds. Results. The analysis of the State register for the period of 2002–2012 showed that there was the tendency not only towards increasing quantity of sorghum crops in general but their substitution by hybrids of foreign breeding. During the period from 2002 to 2017, 72 sorghum varieties were entered on the State register in total, among them only 12 varieties were of domestic breeding, the rest 60 was presented by foreign breeding institutions. Investigation results allowed to determine that the production of base and prebase seeds of sorghum in 2010 amounted to 1,3 t, in 2016 was 43 t. During the same period the production of sugar sorghum increased from 0,2 to 12,0 t, grass sorghum – from 4,0 to 83 t. In 2017, requirements of acreage of such crops as grass sorghum and broomcorn were completely satisfied by the amount of grown seeds. At the same time, the need for seeds of sorghum and sugar sorghum can not be covered completely at the expense of domestic varieties reproduction. In 2017, general demand for sorghum seeds was 400,5 t, among which only 42,0 t was of domestic production. The rest demand for seeds will be met at the expense of import of foreign breeding seeds into the country to be grown and prepared for sowing abroad. Conclusions. In the Register of plant varieties suitable for dissemination in Ukraine, there are 72 sorghum varieties among them only 12 varieties were of domestic breeding, that is 17%, as compared to 83% of recommended great sorghum varieties of foreign breeding. In Ukraine, the area occupied by sorghum cultivation was 22,8 thou ha in 2005, up to 2017 it increased to 89,0 thou ha, and accordingly the demand for seeds run up from 102,6 to 400,5 t. The area occupied by the sugar sorghum in 2005 amounted to only 2,6 thou ha, in 2017 – 20,0 thou ha, that accordingly determined increase of demand for seed material from 13,0 to 99

    ; according to the experience from the old design no major problems are expected concerning stress levels and gap formation in the pebble beds; in fact, the situation should be more favourable due to the reduced dimensions (max. 20 cm) of the beds that should minimise ratcheting and particle flow phenomena. In respect to tritium extraction, the most favourable features of the HCPB concept (e.g. an overall low partial pressure of tritium in the beds that minimise permeation into the main coolant system) can be kept in the new design; a complication could be the necessity to provide each cell with a system of tubes to inlet the purge helium in the front part of the beds or to divide the purge flow for Be and CB. The modular design of the new HCPB blanket, that makes the breeder units almost independent on the structural design of the box, opens interesting possibilities in the development of these units. The present design can be optimised on the basis of the results of the present R and D programme on Be and CB. In addition, new requirements could appear to improve the design performances or manufacturing: i.e. in respect to filling procedures of the beds (use of pre-packed breeder units) or the necessity of insulating layer to thermally decouple the breeder units from the box or the selection of new materials with a better compatibility with Be and CB at high temperatures as protection of the steel structure.

  8. The Role of Consulting a Dictionary in Reading and Vocabulary Learning

    Directory of Open Access Journals (Sweden)

    Carol A. Fraser

    1999-12-01

    Full Text Available Abstract This article reviews recent research on consulting a dictionary in L2 reading and vocabulary learning. From the perspective of cognitive learning theory, the author re-evaluates the limited role that has often been accorded to dictionary consulting. It is noted that, among the three available lexical processing strategies (inferencing, consulting and ignoring, learners tend to use consulting infrequently and selectively and also to differ among each other in their strategy use. Consulting in combination with inferencing is shown to have the greatest positive effect on performance in L2 reading and vocabulary learning, although consulting is found to slow down task completion. Excerpts from think-aloud protocols illustrate the potential contribution of strategic dictionary use to the cognitive processes required for vocabulary acquisition: attention to form-meaning connections, rehearsal of words for storage in long-term memory and elaboration of associations with other knowledge. Among the pedagogical implications of these findings is the need for training in lexical processing strategies in order to help learners use the dictionary effectively and accurately in L2 reading comprehension and vocabulary learning.

    Francis, Michelle Andersen

    Using the vocabulary of a discipline is important for students, especially in the sciences (Gee, 2003). Therefore, the extant literature has emphasized the need for more research on vocabulary knowledge and acquisition (Simpson, et al., 2004). This study investigated whether or not community college students' beliefs about vocabulary knowledge and acquisition changed as a result of a one-semester enrollment in a vocabulary-rich biology course. The rationale for the study, a review of the existing research underlying the study, the methodology of the study, and the results and conclusions of the study will be discussed.

  11. Social validation of vocabulary selection: ensuring stakeholder relevance.

    2013-06-01

    The vocabulary needs of individuals who are unable to spell their messages continue to be of concern in the field of augmentative and alternative communication (AAC). Social validation of vocabulary selection has been suggested as one way to improve the effectiveness and relevance of service delivery in AAC. Despite increased emphasis on stakeholder accountability, social validation is not frequently used in AAC research. This paper describes an investigation of the social validity of a vocabulary set identified in earlier research. A previous study used stakeholder focus groups to identify vocabulary that could be used by South African adults who use AAC to disclose their experiences as victims of crime or abuse. Another study used this vocabulary to create communication boards for use by adults with complex communication needs. In this current project, 12 South African adults with complex communication needs who use AAC systems used a 5-point Likert scale to score the importance of each of the previously identified 57 vocabulary items. This two-step process of first using stakeholder focus groups to identify vocabulary, and then having literate persons who use AAC provide information on social validity of the vocabulary on behalf of their peers who are illiterate, appears to hold promise as a culturally relevant vocabulary selection approach for sensitive topics such as crime and abuse.

    Entities involved in pathways and the events they participate in require descriptive and unambiguous names that are often not available in the literature or elsewhere. Reactome is a manually curated open-source resource of human pathways. It is accessible via a website, available as downloads in standard reusable formats and via Representational State Transfer (REST)-ful and Simple Object Access Protocol (SOAP) application programming interfaces (APIs). We have devised a controlled vocabulary (CV) that creates concise, unambiguous and unique names for reactions (pathway events) and all the molecular entities they involve. The CV could be reapplied in any situation where names are used for pathway entities and events. Adoption of this CV would significantly improve naming consistency and readability, with consequent benefits for searching and data mining within and between databases.

    1997-01-01

    In 1985, the International Atomic Energy Agency issued revised regulations for the safe transport of radioactive material. Significant among the changes were major revisions to requirements for Low Specific Activity (LSA) material and Surface Contaminated Objects (SCOs). In preparation for the adoption of these requirements into regulations in the United States, it became apparent that guidance on how to apply these requirements, clarifying technical uncertainties and ensuring proper implementation, would be needed both by the regulators and those regulated. Thus, the US Department of Transportation and the US Nuclear Regulatory Commission, with the assistance of staff from Oak Ridge National Laboratory, are preparing regulatory guidance for LSA material and SCO transport. The guidance will present examples of acceptable methods for demonstrating compliance with the revised rules. Ideas being investigated for inclusion in the pending guidance are discussed in this paper. Under current plans, the guidance will be issued for public comment prior to final issuance of the guidance in 1997

    2013-05-01

    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.

    Keyword vocabularies are used to tag and to identify data of science data repositories. Such vocabularies consist of controlled terms and the appropriate concepts, such as GCMD1 keywords or the ESPAS2 keyword ontology. The Semantic Web-based mash-up of domain-specific, cross- or even trans-domain vocabularies provides unique capabilities in the network of appropriate data resources. Based on a collaboration between GFZ3, the FHP4, the WDC for Geomagnetism5 and the NICT6 we developed the concept of a vocabulary broker for inter- and trans-disciplinary data detection and integration. Our prototype of the Semantic Web-based vocabulary broker uses OSF7 for the mash-up of geo and space research vocabularies, such as GCMD keywords, ESPAS keyword ontology and SPASE8 keyword vocabulary. The vocabulary broker starts the search with "free" keywords or terms of a specific vocabulary scheme. The vocabulary broker almost automatically connects the different science data repositories which are tagged by terms of the aforementioned vocabularies. Therefore the mash-up of the SKOS9 based vocabularies with appropriate metadata from different domains can be realized by addressing LOD10 resources or virtual SPARQL11 endpoints which maps relational structures into the RDF format12. In order to demonstrate such a mash-up approach in real life, we installed and use a D2RQ13 server for the integration of IUGONET14 data which are managed by a relational database. The OSF based vocabulary broker and the D2RQ platform are installed at virtual LINUX machines at the Kyoto University. The vocabulary broker meets the standard of a main component of the WDS15 knowledge network. The Web address of the vocabulary broker is http://wdcosf.kugi.kyoto-u.ac.jp 1 Global Change Master Directory2 Near earth space data infrastructure for e-science3 German Research Centre for Geosciences4 University of Applied Sciences Potsdam5 World Data Center for Geomagnetism Kyoto6 National Institute of Information and

    2013-12-01

    In this paper we present a controlled vocabulary service application for Environmental Data Store (EDS). The purpose for such application is to help researchers and investigators to archive, manage, share, search, and retrieve data efficiently in EDS. The Simple Knowledge Organization System (SKOS) is used in the application for the representation of the controlled vocabularies coming from EDS. The controlled vocabularies of EDS are created by collecting, comparing, choosing and merging controlled vocabularies, taxonomies and ontologies widely used and recognized in geoscience/environmental informatics community, such as Environment ontology (EnvO), Semantic Web for Earth and Environmental Terminology (SWEET) ontology, CUAHSI Hydrologic Ontology and ODM Controlled Vocabulary, National Environmental Methods Index (NEMI), National Water Information System (NWIS) codes, EPSG Geodetic Parameter Data Set, WQX domain value etc. TemaTres, an open-source, web -based thesaurus management package is employed and extended to create and manage controlled vocabularies of EDS in the application. TemaTresView and VisualVocabulary that work well with TemaTres, are also integrated in the application to provide tree view and graphical view of the structure of vocabularies. The Open Source Edition of Virtuoso Universal Server is set up to provide a Web interface to make SPARQL queries against controlled vocabularies hosted on the Environmental Data Store. The replicas of some of the key vocabularies commonly used in the community, are also maintained as part of the application, such as General Multilingual Environmental Thesaurus (GEMET), NetCDF Climate and Forecast (CF) Standard Names, etc.. The application has now been deployed as an elementary and experimental prototype that provides management, search and download controlled vocabularies of EDS under SKOS framework.

    Full Text Available In order to be able to fully develop their academic and professional competencies, medical doctors (MDs need to be highly proficient in English, which, among other things, implies the acquisition of vocabulary as an essential part of language knowledge. The current study aims at exploring vocabulary learning strategies (VLS employed by freshman and sophomore medical students at the University of Split School of Medicine, Croatia. In particular, it focuses on (a most and least frequently used VLS; (b relationship between VLS subscales and different types of vocabulary knowledge; (c differences in the mean strategy use between male and female students, and among low-, middle- and high-scoring students. The instruments used in the research were adapted version of the VLS Questionnaire (Pavičić Takač, 2008, p.152 and a vocabulary test designed by the author. The results indicate that medical students use a core inventory of VLS, whereby showing preference for the category of self-initiated vocabulary learning (SI-IVL strategies and some individual formal vocabulary learning (FVL and spontaneous vocabulary learning (SVL strategies. Although students were not in favour of FVL at the level of the category as a whole, the results showed that the more frequently they employed FVL strategies, the better they scored on vocabulary tasks measuring controlled-productive type of vocabulary knowledge. Correlations revealed that female students used SI-IVL and FVL strategies significantly more often than their male counterparts. Results also suggest that there are no statistically significant differences in the mean VLS use among low-, middle- and high-scoring students. In conclusion, the results of this study provide a preliminary insight into the VLS used by medical students and their effect on students' vocabulary learning outcomes as well as into differences by gender and vocabulary proficiency. Since findings have proved rather inconclusive, these

  2. The effect of using low-polluting building materials on ventilation requirements and energy use in buildings

    2007-07-01

    The main objective of the ongoing research project described in this paper was to study the potential for reducing energy used for ventilating buildings by using low-polluting building materials, without compromising the indoor air quality. To quantify this potential, the exposure-response relationships, i.e. the relationships between ventilation rate and perceived indoor air quality, were established for rooms furnished with different categories of polluting materials and the simulations of energy used for ventilation were carried out. The exposure-response relationships were based on a summary of data reported in the literature on exposure-response relationships for materials tested in laboratory settings in small-scale glass chambers, and in full-scale in climate chambers, test rooms or normal offices. New experiments were also considered in which the effect of using low-polluting materials on perceived air quality was examined in test rooms ventilated with different outdoor air supply rates, low-polluting materials being selected in small glass chambers. The results suggest that the exposure-response relationships vary between different building materials and that the perceived air quality can be improved considerably when polluting building materials are substituted with materials that pollute less. The preliminary energy simulations indicate that selecting low-polluting materials will result in considerable energy savings as a result of reducing the ventilation rates required to achieve acceptable indoor air quality.

  10. Meeting Radiation Protection Requirements and Reducing Spacecraft Mass - A Multifunctional Materials Approach

    Atwell, William; Koontz, Steve; Reddell, Brandon; Rojdev, Kristina; Franklin, Jennifer

    2010-01-01

    Both crew and radio-sensitive systems, especially electronics must be protected from the effects of the space radiation environment. One method of mitigating this radiation exposure is to use passive-shielding materials. In previous vehicle designs such as the International Space Station (ISS), materials such as aluminum and polyethylene have been used as parasitic shielding to protect crew and electronics from exposure, but these designs add mass and decrease the amount of usable volume inside the vehicle. Thus, it is of interest to understand whether structural materials can also be designed to provide the radiation shielding capability needed for crew and electronics, while still providing weight savings and increased useable volume when compared against previous vehicle shielding designs. In this paper, we present calculations and analysis using the HZETRN (deterministic) and FLUKA (Monte Carlo) codes to investigate the radiation mitigation properties of these structural shielding materials, which includes graded-Z and composite materials. This work is also a follow-on to an earlier paper, that compared computational results for three radiation transport codes, HZETRN, HETC, and FLUKA, using the Feb. 1956 solar particle event (SPE) spectrum. In the following analysis, we consider the October 1989 Ground Level Enhanced (GLE) SPE as the input source term based on the Band function fitting method. Using HZETRN and FLUKA, parametric absorbed doses at the center of a hemispherical structure on the lunar surface are calculated for various thicknesses of graded-Z layups and an all-aluminum structure. HZETRN and FLUKA calculations are compared and are in reasonable (18% to 27%) agreement. Both codes are in agreement with respect to the predicted shielding material performance trends. The results from both HZETRN and FLUKA are analyzed and the radiation protection properties and potential weight savings of various materials and materials lay-ups are compared.

  11. Future materials requirements for the high-energy-intensity production of aluminum

    Science.gov (United States)

    Welch, B. J.; Hyland, M. M.; James, B. J.

    2001-02-01

    Like all metallurgical industries, aluminum smelting has been under pressure from two fronts—to give maximum return on investment to the shareholders and to comply with environmental regulations by reducing greenhouse emissions. The smelting process has advanced by improving efficiency and productivity while continuing to seek new ways to extend the cell life. Materials selection (particularly the use of more graphitized cathodic electrodes) has enabled lower energy consumption, while optimization of the process and controlling in a narrow band has enabled increases in productivity and operations at higher current densities. These changes have, in turn, severely stressed the materials used for cell construction, and new problems are emerging that are resulting in a reduction of cell life. The target for aluminum electro-winning has been to develop an oxygen-evolving electrode, rather than one that evolves substantial amounts of carbon dioxide. Such an electrode, when combined with suitable wettable cathode material developments, would reduce operating costs by eliminating the need for frequent electrode change and would enable more productive cell designs and reduce plant size. The materials specifications for developing these are, however, an extreme challenge. Those specifications include minimized corrosion rate of any electrode into the electrolyte, maintaining an electronically conducting oxidized surface that is of low electrical resistance, meeting the metal purity targets, and enabling variable operating current densities. Although the materials specifications can readily be written, the processing and production of the materials is the challenge.

  2. Uranium refining in South Africa. The production of uranium trioxide, considering raw material properties and nuclear purity requirements

    International Nuclear Information System (INIS)

    Colborn, R.P.; Bayne, D.L.G.; Slabber, M.N.

    1980-01-01

    Conventional practice results in raw materials being delivered to the uranium refineries in a form more suitable for transportation than for processing, and therefore the refineries are required to treat these raw materials to produce an acceptable intermediate feed stock. During this treatment, it is advantageous to include a purification step to ensure that the feed stock is of the required purity for nuclear grade uranium hexafluoride production, and this usually results in ammonium diuranate slurries of the required quality being produced as the intermediate feed stock. All subsequent processing steps can therefore be standardized and are effectively independent of the origin of the raw materials. It is established practice in South Africa to transport uranium as an ammonium diuranate slurry from the various mines to the Nufcor central processing plant for UOC production, and therefore the process for the production of uranium hexafluoride in South Africa was designed to take cognizance of existing transport techniques and to accept ammonium diuranate slurries as the raw material. The South African refinery will be able to process these slurries directly to uranium trioxide. This paper discusses the conditions under which the various ammonium diuranate raw materials, exhibiting a wide range of properties, can be effectively processed to produce a uranium trioxide of acceptably consistent properties. Mention is also made of the uranium hexafluoride distillation process adopted

    International Nuclear Information System (INIS)

    1999-01-01

    The ADR and RID Framework Directives require EC member states' arrangements for the carriage of dangerous goods on domestic road and rail journeys to align with the existing ADR and RID agreements which cover international journeys by road and rail. Because ADR and RID are updated every two years in line with technical and scientific developments, the ADR/RID Framework Directives are also revised on a two-year cycle, to require member states to amend their implementing legislation accordingly. In Great Britain, these two Directives were initially implemented on 1 September 1996 via regulations (usually referred to as the 'carriage regulations'), containing the general legal duties, supported by approved documents, and an Approved Code of Practice containing the detailed technical requirements. The following approved documents have been updated: (a) Approved Vehicle Requirements (AVR) - L89; (b) Approved Requirements and test methods for the classification and packaging of dangerous goods for carriage (ARTM) - L88; (c) Approved Requirements for the packaging, labelling and carriage of radioactive material by rail (ARCRR) - L94; (d) Approved Requirements for the construction of vehicles intended for the carriage of explosives by road (AEVR) - L92; and (e) Approved Carriage List (ACL) - L90

    Kugelmass, Rachel

    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.

    A statement is given of material properties information needed in connection with the structural design technology for liquid-metal fast breeder reactor (LMFBR) primary circuit components. Implementation of current analysis methods and criteria is considered with an emphasis on data and data correlations for performing elastic-plastic and creep analyses, for establishing allowable stress limits, and for computing creep-fatigue damage. Further development of the technology is discussed in relation to properties information. Emphasis is placed on improved constitutive equations for representing inelastic material behavior, on procedures for treating time-dependent fatigue, and on criteria for creep rupture. The properties are generally discussed without regard to specific alloys, since most categories of information are needed for each major structural material. Some sample experimental results are given for type 304 stainless steel and 2 1/4 Cr-1 Mo steel. (author)

    2017-05-01

    Full Text Available Gaining a wider vocabulary is fundamental to language learning. It follows then that the faster students engage and learn new words, the faster will be their proficiency with the target language. Multi-Dimensional Vocabulary Acquisition (or MDVA means approaching new terms / concepts from a variety of perspectives so that the target word is thoroughly analysed, giving students access to all dimensions of the word. There are many dimensions or elements that will help elucidate and unlock meaning, but for the purposes of this chapter new words will be looked at in terms of their antonyms, synonyms and associated words, rhyming counterparts, idiomatic usage, gender considerations, diminutive implications, proverbial usage and likely confusion with other words. In this study the author employs an Action Research methodology where practical classroom exercises involving students’ writing efforts pre- and post MDVA are closely examined. Using the familiar “spiral of cycles” approach, it becomes clear that “unpacking” the target word means that the meaning of many other words associated with the target word becomes explicit. A workshop with faculty is included as part of the practical application of MDVA.

  11. Gradient phonological inconsistency affects vocabulary learning.

    Science.gov (United States)

    Muench, Kristin L; Creel, Sarah C

    2013-09-01

    Learners frequently experience phonologically inconsistent input, such as exposure to multiple accents. Yet, little is known about the consequences of phonological inconsistency for language learning. The current study examines vocabulary acquisition with different degrees of phonological inconsistency, ranging from no inconsistency (e.g., both talkers call a picture /vig/) to mild but detectable inconsistency (e.g., one talker calls a picture a /vig/, and the other calls it a /vIg/), up to extreme inconsistency (e.g., the same picture is both a /vig/ and a /dIdʒ/). Previous studies suggest that learners readily extract consistent phonological patterns, given variable input. However, in Experiment 1, adults acquired phonologically inconsistent vocabularies more slowly than phonologically consistent ones. Experiment 2 examined whether word-form inconsistency alone, without phonological competition, was a source of learning difficulty. Even without phonological competition, listeners learned faster in 1 accent than in 2 accents, but they also learned faster in 2 accents (/vig/ = /vIg/) than with completely different labels (/vig/ = /dIdʒ/). Overall, results suggest that learners exposed to multiple accents may experience difficulty learning when 2 forms mismatch by more than 1 phonological feature, plus increased phonological competition due to a greater number of word forms. Implications for learning from variable input are discussed. PsycINFO Database Record (c) 2013 APA, all rights reserved.

  12. Graded approach for establishment of QA requirements for Type B packaging of radioactive material

    International Nuclear Information System (INIS)

    Fabian, R.R.; Woodruff, K.C.

    1988-01-01

    A study that was conducted by the Nuclear Regulatory Commission for the U.S. Congress to assess the effectiveness of quality assurance (QA) activities has demonstrated a need to modify and improve the application of QA requirements for the nuclear industry. As a result, the packaging community, along with the nuclear industry as a whole, has taken action to increase the efficacy of the QA function. The results of the study indicate that a graded approach for establishing QA requirements is the preferred method. The essence of the graded approach is the establishment of applicable QA requirements to an extent consistent with the importance to safety of an item, component, system, or activity. This paper describes the process that is used to develop the graded approach for QA requirements pertaining to Type B packaging

    A way to improve the quality of learning in the course of Plant Metabolism in the Department of Biology, State University of Malang, is to develop teaching materials. This research evaluates the needs of bioinformatics-based teaching material in the course Plant Metabolism by the Analyze, Design, Develop, Implement, and Evaluate (ADDIE) development model. Data were collected through questionnaires distributed to the students in the Plant Metabolism course of the Department of Biology, University of Malang, and analysis of the plan of lectures semester (RPS). Learning gains of this course show that it is not yet integrated into the field of bioinformatics. All respondents stated that plant metabolism books do not include bioinformatics and fail to explain the metabolism of a chemical compound of a local plant in Indonesia. Respondents thought that bioinformatics can explain examples and metabolism of a secondary metabolite analysis techniques and discuss potential medicinal compounds from local plants. As many as 65% of the respondents said that the existing metabolism book could not be used to understand secondary metabolism in lectures of plant metabolism. Therefore, the development of teaching materials including plant metabolism-based bioinformatics is important to improve the understanding of the lecture material in plant metabolism.

    Fracture toughness requirements of reactor vessel material that must be met by applicants for nuclear power plants construction permit has been investigated in this paper. The fracture toughness should be described in the Safety Analysis Reports (SARs) document that will be evaluated by the Nuclear Energy Regulatory Agency (BAPETEN). Because BAPETEN does not have a regulations or standards/codes regarding the material used for the reactor vessel, especially in the fracture toughness requirements, then the acceptance criteria that applied to evaluate the fracture toughness of reactor vessel material refers to the regulations/provisions from the countries that have been experienced in the operation of nuclear power plants, such as from the United States, Japan and Korea. Regulations and standards used are 10 CFR Part 50, ASME and ASTM. Fracture toughness of reactor vessel materials are evaluated to ensure compliance of the requirements and provisions of the Regulatory Body and the applicable standards, such as ASME or ASTM, in order to assure a reliability and integrity of the reactor vessels as well as providing an adequate safety margin during the operation, testing, maintenance, and postulated accident conditions over the reactor vessel lifetime.

    TERA's estimates of capital requirements to transport natural gas, crude oil, petroleum products, and coal in the US by 1990 are presented. It is a continuation of a 1978 study (EAPA 5:3946) to perform a similar analysis on 1979 scenarios. Scenarios B, C, and D from the EIA's Mid-range Energy Forecasting Systems, as used in the 1979 Annual Report to Congress (ARC), were provided as a basis for the analysis and represent three alternative futures. Summaries of transportation investment requirements through 1990 are given for Scenarios B, C, and D. Total investment requirements for the three models (pipelines, railroads, waterways) and the three energy commodities (coal, petroleum, petroleum products, natural gas) are estimated to range between $35.3 and $42.7 billion by 1990 depending on the scenario.

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

    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.

    2010-07-01

    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.

    2018-03-01

    Vocabulary learning reflects the language experiences of the child, both in typical and atypical development, although the vocabulary development of children who use aided communication may differ from children who use natural speech. This study compared the performance of children using aided communication with that of peers using natural speech on two measures of vocabulary knowledge: comprehension of graphic symbols and labeling of common objects. There were 92 participants not considered intellectually disabled in the aided group. The reference group consisted of 60 participants without known disorders. The comprehension task consisted of 63 items presented individually in each participant's graphic system, together with four colored line drawings. Participants were required to indicate which drawing corresponded to the symbol. In the expressive labelling task, 20 common objects presented in drawings had to be named. Both groups indicated the correct drawing for most of the items in the comprehension tasks, with a small advantage for the reference group. The reference group named most objects quickly and accurately, demonstrating that the objects were common and easily named. The aided language group named the majority correctly and in addition used a variety of naming strategies; they required more time than the reference group. The results give insights into lexical processing in aided communication and may have implications for aided language intervention.

    State and local laws requiring notification for shipments of radioactive and other hazardous materials have become increasingly common and controversial during the last decade. Such laws are seen by their proponents as essential for planning and emergency response, while their opponents view them as unnecessary and intrusive. The debate over the value of notification requirements has often been hampered by the lack of information about the extent and nature of these laws. The report is intended to present factual information about notification laws in order to facilitate more informed discussion

    Recent developments in the formulation of detection capability and accuracy criteria for bioassay measurements will be interpreted and adapted to provide similar criteria for the measurement of air concentrations of radioactive material for radiation protection purposes. Considerations of accuracy will be related to the known variability of measurement processes, as well as the uncertainties in the calculated limits of intake that serve as the basis of regulatory and voluntary standards of practice. Formulations and criteria will be presented for minimum detection amounts (MDA) and precision and bias of measurements for radiation protection purposes. 17 references

  16. Vocabulary Growth in College-Level Students’ Narrative Writing

    Hicham ZYAD

    2017-09-01

    Full Text Available The nature and size of vocabulary significantly determine quality in a given piece of writing. It therefore follows that an extensive vocabulary repertoire is a key factor to success in academic life. Most certainly, this explains the vast amount of scholarly attention that has been invested in this line of research. In this regard, a wide array of studies have provided evidence suggesting that human assessors of writing quality are substantially influenced by the range and sophistication of the vocabulary used by L2 learners. The studies that offered such evidence used different measurement tools to evaluate the nature and/or size of L2 learners’ vocabulary. However, very few studies have attempted to chart vocabulary knowledge across different college-level proficiency levels in narrative writing productions in the Moroccan context. To contribute to this debate, the present study aims to investigate university L2 learners’ vocabulary knowledge across three proficiency levels from two post-secondary institutions. More specifically, this cross-sectional study operationalized vocabulary knowledge in terms of diversity and sophistication in order to chart growth in the lexical repertoire of 90 participants. Data analysis showed that the participants displayed different levels of vocabulary knowledge. In terms of lexical diversity, second-year students’ vocabulary was as diverse as third-year students but it was not as sophisticated. Nonetheless, sophistication did not differentiate first- and second-year students but it did differentiate between second- and third-year students. Additionally, diversity and sophistication were both good markers of difference between first- and second-year students. The implications of the findings will be discussed.

  17. Domain Independent Vocabulary Generation and Its Use in Category-based Small Footprint Language Model

    Directory of Open Access Journals (Sweden)

    KIM, K.-H.

    2011-02-01

    Full Text Available The work in this paper pertains to domain independent vocabulary generation and its use in category-based small footprint Language Model (LM. Two major constraints of the conventional LMs in the embedded environment are memory capacity limitation and data sparsity for the domain-specific application. This data sparsity adversely affects vocabulary coverage and LM performance. To overcome these constraints, we define a set of domain independent categories using a Part-Of-Speech (POS tagged corpus. Also, we generate a domain independent vocabulary based on this set using the corpus and knowledge base. Then, we propose a mathematical framework for a category-based LM using this set. In this LM, one word can be assigned assign multiple categories. In order to reduce its memory requirements, we propose a tree-based data structure. In addition, we determine the history length of a category n-gram, and the independent assumption applying to a category history generation. The proposed vocabulary generation method illustrates at least 13.68% relative improvement in coverage for a SMS text corpus, where data are sparse due to the difficulties in data collection. The proposed category-based LM requires only 215KB which is 55% and 13% compared to the conventional category-based LM and the word-based LM, respectively. It successively improves the performance, achieving 54.9% and 60.6% perplexity reduction compared to the conventional category-based LM and the word-based LM in terms of normalized perplexity.

    Investigations in mechanobiology rely on correlation of cellular processes with mechanical signals, such as matrix stiffness and cell tractions. Almost all cell traction and force quantification methodologies require knowledge of the underlying mechanical properties of the extracellular matrix to convert displacement data into corresponding traction data, which restricts the use of these techniques to systems in which the material properties are known. To overcome this hurdle, we present a ne...

    This reference document is produced in cooperation with partners in the Union Latine, an international organization dedicated to promoting the Romance languages. In 1992 acting on a request submitted by the Montreal Environment Section of the Translation Bureau, the Terminology and Standardization Directorate published an in-house glossary containing 2500 entries on nuclear waste management. The glossary was produced by scanning bilingual terms in the reports submitted to Atomic Energy of Canada Limited by the Siting Process Task Force on Low-Level Radioactive Waste Disposal. Because the scale of the nuclear waste management problem has grown considerably since then, the glossary needed to be expanded and revised. The Vocabulary contains some 1000 concepts for a total of approximately 3000 terms in each of the three languages, english, french and spanish. Special attention has been given to defining basic physical concepts, waste classifications and disposal methods

    An experiment investigated whether exposure to orthography facilitates oral vocabulary learning. A total of 58 typically developing children aged 8-9 years were taught 12 nonwords. Children were trained to associate novel phonological forms with pictures of novel objects. Pictures were used as referents to represent novel word meanings. For half of the nonwords children were additionally exposed to orthography, although they were not alerted to its presence, nor were they instructed to use it. After this training phase a nonword-picture matching posttest was used to assess learning of nonword meaning, and a spelling posttest was used to assess learning of nonword orthography. Children showed robust learning for novel spelling patterns after incidental exposure to orthography. Further, we observed stronger learning for nonword-referent pairings trained with orthography. The degree of orthographic facilitation observed in posttests was related to children's reading levels, with more advanced readers showing more benefit from the presence of orthography.

    Full Text Available Abstract: The present study was conducted to investigate types of Multiple Intelligences as predictors of reading comprehension and vocabulary knowledge. To meet this objective, a 60-item TOEFL test and a 90-item multiple intelligences questionnaire were distributed among 240 male and female Iranians studying English at Qazali and Parsian Universities in Qazvin. Data were analyzed using a multiple regression procedure. The result of the data analysis indicated that musical, interpersonal, kinesthetic, and logical intelligences were predicators of reading comprehension. Moreover, musical, verbal, visual, kinesthetic and natural intelligences made significant contributions to predicting vocabulary knowledge.   Key words: Multiple intelligences, reading comprehension, vocabulary knowledge.

  4. Information or resolution: Which is required from an SEM to study bulk inorganic materials?

    Science.gov (United States)

    2016-11-01

    Significant technological advances in scanning electron microscopy (SEM) have been achieved over the past years. Different SEMs can have significant differences in functionality and performance. This work presents the perspectives on selecting an SEM for research on bulk inorganic materials. Understanding materials demands quantitative composition and orientation information, and informative and interpretable images that reveal subtle differences in chemistry, orientation/structure, topography, and electronic structure. The capability to yield informative and interpretable images with high signal-to-noise ratios and spatial resolutions is an overall result of the SEM system as a whole, from the electron optical column to the detection system. The electron optical column determines probe performance. The roles of the detection system are to capture, filter or discriminate, and convert signal electrons to imaging information. The capability to control practical operating parameters including electron probe size and current, acceleration voltage or landing voltage, working distance, detector selection, and signal filtration is inherently determined by the SEM itself. As a platform for various accessories, e.g. an energy-dispersive spectrometer and an electron backscatter diffraction detector, the properties of the electron optical column, specimen chamber, and stage greatly affect the performance of accessories. Ease-of-use and ease-of-maintenance are of practical importance. It is practically important to select appropriate test specimens, design suitable imaging conditions, and analyze the specimen chamber geometry and dimensions to assess the overall functionality and performance of an SEM. For an SEM that is controlled/operated with a computer, the stable software and user-friendly interface significantly improve the usability of the SEM.

The current study is a follow-up research of a similar study by Vandergrift and Tafaghodtari (2010. However, we sought to expand the previous research by investigating the relationship between the students’ current level of L2 (target language vocabulary and listening test scores. Our study likewise differed in the sample of participants, the target language, teaching and testing material used, and the duration of the very experiment. To answer the proposed research questions we conducted an experiment with 57 Serbian secondary school EFL (English as a Foreign Language learners divided into experimental (n=27 and control group (n=30. The results of the pre- and post-tests of the two groups showed the beneficial effects of developing metacognitive strategies and the strong positive correlation between the level of vocabulary and listening comprehension. The paper underlines important pedagogical implications especially regarding the enhancement of metacognitive awareness and vocabulary proficiency of students in order to improve performance on listening comprehension tasks.

    The issuance of the Waste Isolation Pilot Plant's (WIPP) Hazardous Waste Facility Permit in August of 2000, specifically the attachment I3 Waste Analysis Plan (WAP),had a profound impact upon transuranic (TRU) waste certification at Los Alamos National Laboratory's (LANL) Plutonium Facility. Program certification was lost until Laboratory internal program documents could be amended to meet the new WAP requirements, waste management personnel could be retrained to incorporate the changes into waste operations and the entire program successfully pass subsequent Carlsbad Field Ofice (CBFO) audit. This action resulted in the suspension of transuranic waste shipments from LANL to WIPP. In addition the changes unnecessarily increased the complexity of TRU waste program activities in waste handling.

    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.

    Full Text Available Vocabulary acquisition concerns on how people expand the numbers of words they understand when learning a new language. Knowing words in a second or foreign language is vitally important because the reader will be able to understand the written text well and the speaker will be able to communicate basic ideas through vocabulary even if the person does not understand how to create a grammatically correct sentence. As Madsen argued, “mastering vocabulary is the primary thing that every student should acquire in learning English” (Harold, 1983. Therefore, acquiring a sufficiently large vocabulary is one of the important tasks faced by L2 learners in order to comprehend the written texts in reading as one of the four basic features of language learning.

  18. The digital history of the anglophone vocabulary of psychology: An exploration using Zipfian methods.

    2016-05-01

    The digital humanities are being applied with increasing frequency to the analysis of historically important texts. In this study, the methods of G. K. Zipf are used to explore the digital history of the vocabulary of psychology. Zipf studied a great many phenomena, from word frequencies to city sizes, showing that they tend to have a characteristic distribution in which there are a few cases that occur very frequently and many more cases that occur very infrequently. We find that the number of new words and word senses that writers contribute to the vocabulary of psychology have such a Zipfian distribution. Moreover, those who make the most contributions, such as William James, tend also to invent new metaphorical senses of words rather than new words. By contrast, those who make the fewest contributions tend to invent entirely new words. The use of metaphor makes a text easier for a reader to understand. While the use of new words requires more effort on the part of the reader, it may lead to more precise understanding than does metaphor. On average, new words and word senses become a part of psychology's vocabulary in the time leading up to World War I, suggesting that psychology was "finding its language" (Danziger, 1997) during this period.

    2017-08-16

    Recent studies indicate that school-age children's patterns of performance on measures of verbal and visuospatial short-term memory (STM) and working memory (WM) differ across types of neurodevelopmental disorders. Because these disorders are often characterized by early language delay, administering STM and WM tests to toddlers could improve prediction of neurodevelopmental outcomes. Toddler-appropriate verbal, but not visuospatial, STM and WM tasks are available. A toddler-appropriate visuospatial STM test is introduced. Tests of verbal STM, visuospatial STM, expressive vocabulary, and receptive vocabulary were administered to 92 English-speaking children aged 2-5 years. Mean test scores did not differ for boys and girls. Visuospatial and verbal STM scores were not significantly correlated when age was partialed out. Age, visuospatial STM scores, and verbal STM scores accounted for unique variance in expressive (51%, 3%, and 4%, respectively) and receptive vocabulary scores (53%, 5%, and 2%, respectively) in multiple regression analyses. Replication studies, a fuller test battery comprising visuospatial and verbal STM and WM tests, and a general intelligence test are required before exploring the usefulness of these STM tests for predicting longitudinal outcomes. The lack of an association between the STM tests suggests that the instruments have face validity and test independent STM skills.

  1. Semantic Interoperability Almost Without Using The Same Vocabulary: Is It Possible?

    Science.gov (United States)

    Krisnadhi, A. A.

    2016-12-01

    Semantic interoperability, which is a key requirement in realizing cross-repository data integration, is often understood as using the same ontology or vocabulary. Consequently, within a particular domain, one can easily assume that there has to be one unifying domain ontology covering as many vocabulary terms in the domain as possible in order to realize any form of data integration across multiple data sources. Furthermore, the desire to provide very precise definition of those many terms led to the development of huge, foundational and domain ontologies that are comprehensive, but too complicated, restrictive, monolithic, and difficult to use and reuse, which cause common data providers to avoid using them. This problem is especially true in a domain as diverse as geosciences as it is virtually impossible to reach an agreement to the semantics of many terms (e.g., there are hundreds of definitions of forest used throughout the world). To overcome this challenge, modular ontology architecture has emerged in recent years, fueled among others, by advances in the ontology design pattern research. Each ontology pattern models only one key notion. It can act as a small module of a larger ontology. Such a module is developed in such a way that it is largely independent of how other notions in the same domain are modeled. This leads to an increased reusability. Furthermore, an ontology formed out of such modules would have an improved understandability over large, monolithic ontologies. Semantic interoperability in the aforementioned architecture is not achieved by enforcing the use of the same vocabulary, but rather, promoting alignment to the same ontology patterns. In this work, we elaborate how this architecture realizes the above idea. In particular, we describe how multiple data sources with differing perspectives and vocabularies can interoperate through this architecture. Building the solution upon semantic technologies such as Linked Data and the Web Ontology

    2013-01-01

    The majority of transports of radioactive materials are carried out in packages which don't need a package design approval by a competent authority. Low-active radioactive materials are transported in such packages e.g. in the medical and pharmaceutical industry and in the nuclear industry as well. Decommissioning of NPP's leads to a strong demand for packages to transport low and middle active radioactive waste. According to IAEA regulations the 'non-competent authority approved package types' are the Excepted Packages and the Industrial Packages of Type IP-1, IP-2 and IP-3 and packages of Type A. For these types of packages an assessment by the competent authority is required for the quality assurance measures for the design, manufacture, testing, documentation, use, maintenance and inspection (IAEA SSR 6, Chap. 306). In general a compliance audit of the manufacturer of the packaging is required during this assessment procedure. Their regulatory level in the IAEA regulations is not comparable with the 'regulatory density' for packages requiring competent authority package design approval. Practices in different countries lead to different approaches within the assessment of the quality assurance measures in the management system as well as in the quality assurance program of a special package design. To use the package or packaging in a safe manner and in compliance with the regulations a management system for each phase of the life of the package or packaging is necessary. The relevant IAEA-SSR6 chap. 801 requires documentary verification by the consignor concerning package compliance with the requirements. (authors)

    Both Islam and Christianity warn their adherents not to view or to display obscene matter. Aside from religious consequences in the afterlife for such behavior, this study was conducted to determine if viewing sexual media has a detrimental effect in earthly life. Adolescents (n = 64) 17-22 years were exposed to two types of visual stimuli containing sexual or neutral content for 30 min. The participants, seated in rooms with comfortable chairs and provided with snacks, were shown a selection of 18 German words via a PowerPoint slideshow, which included a picture, an audio recording, and the written form of each word. The experimental group, which was exposed to arousing visual stimuli with mild sexual content (movie trailers, music video clips, and TV commercials), remembered significantly fewer words than the control group, which viewed a nature documentary without sexual content. T-test scores revealed that exposure to sexually arousing media impaired memory for second language (L2) vocabulary. Apart from leading to dire consequences in the hereafter, the results of the study demonstrate that viewing obscene material also causes harm in this life.

    The aim of this study was to develop a core vocabulary list for young children with intellectual disabilities between 2 and 7 years of age because data from this population are lacking in core vocabulary literature. Children with Down syndrome are considered one of the most valid reference groups for researching developmental patterns in children with intellectual disabilities; therefore, spontaneous language samples of 30 Dutch children with Down syndrome were collected during three different activities with multiple communication partners (free play with parents, lunch- or snack-time at home or at school, and speech therapy sessions). Of these children, 19 used multimodal communication, primarily manual signs and speech. Functional word use in both modalities was transcribed. The 50 most frequently used core words accounted for 67.2% of total word use; 16 words comprised core vocabulary, based on commonality. These data are consistent with similar studies related to the core vocabularies of preschoolers and toddlers with typical development, although the number of nouns present on the core vocabulary list was higher for the children in the present study. This finding can be explained by manual sign use of the children with Down syndrome and is reflective of their expressive vocabulary ages.

    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.

  9. Linking vocabulary to imagery: Improving science knowledge through multimedia design

    Science.gov (United States)

    Adler, Tracy R.

    This qualitative study looked at the vocabulary development of four urban sixth-grade students as they used laser disk and computer technologies to view images and then connect those images to textual definitions through multimedia design. Focusing on three science content areas (the water cycle, the rock cycle, and the web of life), students worked in pairs to create their own multimedia stacks that focused on the prescribed vocabulary. Using a combination of text, images, and audio, students demonstrated their understanding of content vocabulary words and how these words are interconnects within a science topic. Further, the study examined the impact that linking images to vocabulary and textual definitions has on helping students memorize definitions of the science content words. It was found that the use of imagery had a positive affect on the students' ability to identify textual definitions and vocabulary words, though it did not have a great impact on their later recall of word/definition connections. In addition, by designing their own multimedia artifacts, students were able to connect the vocabulary and images within a specific content area and explain their function within a broader science concept. The results of this study were inconclusive as to the impact this activity had on the students' ability to transfer their knowledge to correctly answering questions similar to the ones they see on their state proficiency exam.

    2008-06-01

    Although vocabulary tests are generally considered interchangeable, regardless of format, different tests can have different relations to age and to other cognitive abilities. In this study, 4 vocabulary test formats were examined: multiple-choice synonyms, multiple-choice antonyms, produce the definition, and picture identification. Results indicated that, although they form a single coherent vocabulary knowledge factor, the formats have different relations to age. In earlier adulthood, picture identification had the strongest growth, and produce the definition had the weakest. In later adulthood, picture identification had the strongest decline, and multiple-choice synonyms had the least. The formats differed in their relation to other cognitive variables, including reasoning, spatial visualization, memory, and speed. After accounting for the differential relations to other cognitive variables, differences in relation to age were eliminated with the exception of differences for the picture identification test. No theory of the aging of vocabulary knowledge fully explains these findings. These results suggest that using a single indicator of vocabulary may yield incomplete and somewhat misleading results about the aging of vocabulary knowledge.

    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.

    Full Text Available This study investigates the perceptions of students towards Application-Based Crossword Puzzles and how playing this game can affect the development of vocabulary amongst students. Drawing on Vygostky’s Socio-Cultural Theory which states that the human mind is mediated by cultural artifacts, the nature of this game poses challenges and builds curiosity, allowing players to pay more attention to the words to fill in the boxes which subsequently enhances their retention of vocabulary. This game has very good potential to build positive perceptions and to develop cognition in the linguistic domain of players, i.e. the amount of their vocabulary. In this study, the researcher conducted interviews with eligible or selected student players to find out their perceptions toward this game and administered a vocabulary test to find out how this game had added to the retention in memory of new words acquired by the players from the game. The study findings showed that the participants perceive this game positively and it affects the players’ vocabulary retention positively as indicated by their test results. It is recommended that English teachers consider using Application-Based Crossword Puzzles to help students build their vocabularies especially as part of extracurricular activities.

    Full Text Available Abstract Over the recent years the teaching of foreign language vocabulary has been the subject of much discussion and arguments and a number of research and methodology books on such topic have emerged as it is the case for example with Nation 2001 and Schmitt 2000. For a long time grammar seemed to have attracted more attention but this renewed interest in vocabulary reflects the belief that it is becoming a major component in knowing a language and as some recent scholars would admit even more important than grammar already. In addition to the various strategies used to promote vocabulary learning in the classroom environment songs are widely being used nowadays as a powerful tool in teaching new vocabulary to early grades pupils. Throughout our teaching of young learners we have noticed that they are amazingly captured by songs and they always enjoy listening to them. This might be one of the main reasons why songs have now become one of the cornerstones in the demanding and challenging process of teaching children. The purpose of this research paper is to find out as to what extent and how the use of songs may support new vocabulary learning for grade four pupils in Oman and how much it actually helps these young learners in developing their vocabulary learning habits.

  14. Materialism.

    2012-05-01

    Materialism is nearly universally assumed by cognitive scientists. Intuitively, materialism says that a person's mental states are nothing over and above his or her material states, while dualism denies this. Philosophers have introduced concepts (e.g., realization and supervenience) to assist in formulating the theses of materialism and dualism with more precision, and distinguished among importantly different versions of each view (e.g., eliminative materialism, substance dualism, and emergentism). They have also clarified the logic of arguments that use empirical findings to support materialism. Finally, they have devised various objections to materialism, objections that therefore serve also as arguments for dualism. These objections typically center around two features of mental states that materialism has had trouble in accommodating. The first feature is intentionality, the property of representing, or being about, objects, properties, and states of affairs external to the mental states. The second feature is phenomenal consciousness, the property possessed by many mental states of there being something it is like for the subject of the mental state to be in that mental state.

    The increasing population of dual language learners (DLLs) entering preschool classrooms highlights a continued need for research on the development of dual language acquisition, and specifically vocabulary skills, in this age group. 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.

    This study is an attempt to explore the difference between acquiring new words with different semantic fields to which they belong. In other words, the purpose of this study is to scrutinize the contribution of semantic field theory in learning new vocabulary items in an EFL setting. Thirty-eight students of three different levels of education took part in this research. They were exposed to some new words from four different semantic fields, and then they were tested on their acquisition of the words meaning. This exposure was through reading texts and the aim of reading was just comprehension, therefore the words were acquired incidentally. The outcome showed significant differences between groups with different levels of education regarding retention of words from different semantic fields.

  1. Age of acquisition effects in vocabulary learning.

    Palmer, Shekeila D; Havelka, Jelena

    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.

    Cruz, Maria B.

    English language learners studying biology face a dual challenge of mastering both content and language. Teaching ELLs how to engage in scientific discourse using appropriate language to ask, answer, explain, and make predictions about science requires a foundational knowledge of content-specific vocabulary. This study used qualitative interviews with intermediate-level ELLs at an American high school to learn how a supplemental iPod-based vocabulary review tool influenced their perceptions of learning biology vocabulary outside of classroom hours. Interviews with their biology teacher were also used to complement student testimony from the point of view of an educational professional with ELL teaching experience. Past studies in the area of mobile learning have primarily employed questionnaires to gather feedback from participants. This research study adds greater participant voice to the body of literature that encompasses mobile language learning, second language acquisition, and science education by presenting nuanced opinions from both students and teachers. This dissertation concludes with a discussion on the influence that this study could have on further research in the fields of mobile learning, academic vocabulary, and student learning behaviors.

    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.

    Full Text Available Pre-basic seed potato material is used for basic seed (elite and certified seed potato production. At this moment all basic seed material is imported into Republic of Serbia and Republic of Srpska, despite the fact that the method of in vitro tissue culture production of virus-free seed potato has been developed in both countries and there is a continuous demand for pre-basic and basic seed potato. Current total production is significantly lower than actual requirements. In the 80s and 90s of the previous century two modern facilities for production of virus-free seed potato and certified seed were built in Sokolac (Republic of Srpska and Guča (Republic of Serbia. Although facilities were well-equipped, seed potato production was permanently ceased in 2000. The presence of high infection pressure dominated by potato virus Y is shown in the Republic of Serbia and the Republic of Srpska. This paper gives an overview of pre-basic seed potato material production in both countries over the last two decades.

  5. Is vocabulary growth influenced by the relations among words in a language learner's vocabulary?

    2013-09-01

    Several recent studies have explored the applicability of the preferential attachment principle to account for vocabulary growth. According to this principle, network growth can be described by a process in which existing nodes recruit new nodes with a probability that is an increasing function of their connectivity within the existing network. The current study combined subjective estimates of the age of acquisition (AoA) and associations among words in a large corpus to estimate the organization of semantic knowledge at multiple points in vocabulary growth. Consistent with previous studies, the number of connections or relations among words followed a power law distribution in which relatively few words were highly connected with other words and most words were connected to relatively few words. In addition, the growth in the number of connections of a word was a linear function of its initial number of connections, and the ratio of connections to any two words was relatively constant over time. Finally, number of connections to known words was a reliable predictor of a word's AoA. All of these findings can be shown to be consistent with the preferential attachment principle.

    Differences between monolingual and multilingual vocabulary development have been observed but few studies provide a longitudinal perspective on vocabulary development before and following school entry. This study compares vocabulary growth profiles of 106 multilingual children to 211 monolingual peers before and after school entry to examine whether: (1) school entry coincides with different rates of vocabulary growth compared to prior to school entry, (2) compared to monolingual peers, multilingual children show different vocabulary sizes or rates of vocabulary growth, (3) the age of onset of second-language acquisition for multilingual children is associated with vocabulary size or rate of vocabulary growth, and (4) the sociolinguistic context of the languages spoken by multilingual children is associated with vocabulary size or rate of vocabulary growth. Results showed increases in vocabulary size across time for all children, with a steeper increase prior to school entry. A significant difference between monolingual and multilingual children who speak a minority language was observed with regards to vocabulary size at school entry and vocabulary growth prior to school entry, but growth rate differences were no longer present following school entry. Taken together, results suggest that which languages children speak may matter more than being multilingual per se. PMID:29354017

    Full Text Available The present study reports on an action research study that explores the implications of applying three vocabulary strategies: word cards, association with pictures, and association with a topic through fables in the acquisition of new vocabulary in a group of EFL low-level proficiency teenagers in a public school in Espinal, Tolima, Colombia. The participants had never used vocabulary strategies before and struggled to memorize and recall words.  Two types of questionnaires, a researcher’s journal, and vocabulary tests were the instruments used to gather data.  The results showed that these strategies were effective to expand the range of words progressively and improve the ability to recall them. The study also found that these strategies involve cognitive and affective factors that can affect students’ perception about the strategies and their use. The implementation of the strategies highlighted the need to train teachers and learners in strategies intended to teach and learn vocabulary and to include them in the English language program in any school.

    expressive vocabulary of children with normal and deviant phonological development. to determine whether alterations presented by children with phonological disorders occur only at the phonological level or if there are any impacts on lexical acquisition; to compare the vocabulary performance of children with phonological disorders to reference values presented by the used test. participants of the study were 36 children of both genders, 14 with phonological disorders (Study group) and 22 with typical language development (Control Group). The ABFW - Vocabulary Test (Befi-Lopes, 2000) was used for assessing the expressive vocabulary of children and later to compare the performance of both groups. the performance of children with phonological disorder in the expressive vocabulary test is similar to that of children with normal phonological development. Most of the children of both groups reached the benchmarks proposed by the test for the different semantic fields. The semantic field Places demonstrated to be the most complex for both groups. the alterations presented by children with phonological disorder area limited to the phonological level, having no impact on the lexical aspect of language.

    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.

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

    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.

    2007-11-01

    The vocabulary development of 24 Italian children aged between 1;4 and 1;6 at the beginning of the study was longitudinally monitored on a monthly basis using the Italian version of the MacArthur Communicative Development Inventory drawn up by their mothers. This study analyzes data from children for whom two sampling stages were available; the first corresponding to a vocabulary size as close as possible to 200 words (mean 217, range 167-281), the second to a vocabulary size ranging from 400 to 650 words (mean 518, range 416-648). The children's vocabulary composition was analyzed by calculating, for each sampling stage, the percentage of common nouns, verbs and closed-class words. The increase in percentage points of the various lexical items between the first and second sampling stages was also analyzed. Data confirmed the predominance of nouns over verbs and closed-class words at both sampling stages, while verbs and closed-class words showed a higher percentage increase than nouns. The results provide evidence that children who reached the first sampling point at an earlier age had a higher percentage of nouns than children who reached the same stage at an older age. However, in the passage from the first to the second sampling point no relationship emerged between a style of acquisition based on the acquisition of nouns and an increase in the rate of vocabulary growth.

  13. Coherent image layout using an adaptive visual vocabulary

    When querying a huge image database containing millions of images, the result of the query may still contain many thousands of images that need to be presented to the user. We consider the problem of arranging such a large set of images into a visually coherent layout, one that places similar images next to each other. Image similarity is determined using a bag-of-features model, and the layout is constructed from a hierarchical clustering of the image set by mapping an in-order traversal of the hierarchy tree into a space-filling curve. This layout method provides strong locality guarantees so we are able to quantitatively evaluate performance using standard image retrieval benchmarks. Performance of the bag-of-features method is best when the vocabulary is learned on the image set being clustered. Because learning a large, discriminative vocabulary is a computationally demanding task, we present a novel method for efficiently adapting a generic visual vocabulary to a particular dataset. We evaluate our clustering and vocabulary adaptation methods on a variety of image datasets and show that adapting a generic vocabulary to a particular set of images improves performance on both hierarchical clustering and image retrieval tasks.

    The aim of the current study was to examine the relationship between sibship size and children's vocabulary as a function of quality of sibling interactions. It was hypothesized that coming from a larger sibship (ie, 3+ children) would be related to lower receptive vocabulary in children. However, we expected this association to be moderated by the level of cognitive sensitivity shown by children's next-in-age older siblings. Data on 385 children (mean age = 3.15 years) and their next-in-age older siblings (mean age = 5.57 years) were collected and included demographic questionnaires, direct testing of children's receptive vocabulary, and videos of mother-child and sibling interactions. Sibling dyads were taped engaging in a cooperative building task and tapes were coded for the amount of cognitive sensitivity the older sibling exhibited toward the younger sibling. Hierarchical regression analyses were conducted and showed an interaction between sibship size and sibling cognitive sensitivity in the prediction of children's receptive vocabulary; children exposed to large sibships whose next-in-age older sibling exhibited higher levels of cognitive sensitivity were less likely to show low vocabulary skills when compared with those children exposed to large sibships whose siblings showed lower levels of cognitive sensitivity. Children who show sensitivity to the cognitive needs of their younger siblings provide a rich environment for language development. The negative impact of large sibships on language development is moderated by the presence of an older sibling who shows high cognitive sensitivity.

    To determine whether children with mild-to-moderately severe sensorineural hearing loss (CHL) present with disturbances in working memory and whether these disturbances relate to the size of their receptive vocabularies. Children 6 to 9 years of age participated. Aspects of working memory were tapped by articulation rate, forward and backward digit span in the auditory and visual modalities, Corsi span, parent surveys, and a sequential encoding task. Articulation rate, digit spans, and Corsi spans were also administered in low-level broadband noise. CHL and children with normal hearing (CNH) demonstrated auditory advantage in forward serial recall. CHL demonstrated slower articulation rates than CNH, but similar memory spans. CHL with poor executive function presented with poorer performance on the Corsi span task. The presence of background noise had no effect on performance in either group. CHL presented with significantly smaller receptive vocabularies than their CNH peers. Across groups, receptive vocabulary size was positively correlated with digit span in quiet, Corsi span in noise, and articulation rate. In the presence of mild-to-moderately severe hearing loss, children demonstrated resilient working memory systems. For all children, working memory and vocabulary were related; that is, children with poorer working memory had smaller vocabulary sizes.

    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. © Hammill Institute on Disabilities 2013.

Four intact ESL classes were divided into one control group and three treatment groups (keyword, semantic, and keyword-semantic. These Afrikaans-speaking standard 6 pupils then received 4 days of instruction. Both multiplechoice and cued-recall instruments were used to measure effects both 1 day and 9 days after instruction. The results indicated that for both the multiple-choice and cued-recall tests the combined keyword-semantic strategy differed statistically Significantly as well as practically significantly from the keyword method. The results, therefore, suggest that the combined keyword-semantic strategy increased retention above the other strategies. Hierdie artikel vergelyk die effektiwiteit van drie taalleerstrategiee (geheue strategiee vir die aanleer van woordeskat met mekaar.

    The Ontology Lookup Service (OLS) (http://www.ebi.ac.uk/ols) provides interactive and programmatic interfaces to query, browse and navigate an ever increasing number of biomedical ontologies and controlled vocabularies. The volume of data available for querying has more than quadrupled since it went into production and OLS functionality has been integrated into several high-usage databases and data entry tools. Improvements have been made to both OLS query interfaces, based on user feedback and requirements, to improve usability and service interoperability and provide novel ways to perform queries.

  19. An evaluation of the procedures required to ensure consistent material supply in the Eastern Cape automotive industry

    Directory of Open Access Journals (Sweden)

    2014-07-01

    Full Text Available There is a common perception that logistics practice and supply chain management have not yet reached the required international standards among all the supply chain members in the South African automotive industry. This article is based on a research study that investigated possible reasons for the inconsistent supply of materials in the Eastern Cape automotive industry specifically. Problems identified include the fact that suppliers are not evaluated on a regular basis and do not receive sufficient logistics training, while a commitment and will to development local suppliers is lacking. Recommendations made to the South African automotive industry include the improvement of development programmes to assist local suppliers in becoming world-class suppliers, better logistics training, more regular supplier assessments, as well as improved mutual communication among suppliers and motor vehicle assemblers.

    Full Text Available This paper discusses the definition of business rules using business vocabulary and semantics. At the beginning business rules, business vocabulary and semantics of business rules are specified. There is also outlined the current state of research on this topic. Then the definition and formalization of business rules using semantics and business vocabulary is described. Based on these proposed procedures was created a tool that implements and simulate these processes. The main advantage of this tool is “Business Rules Layer”, which implements business rules into the system but is separated from this system. Source code of the rules and the system are not mixed together. Finally, the results are evaluated and future development is suggested.

    Negen, James; Sarnecka, Barbara W

    2012-11-01

    How is number-concept acquisition related to overall language development? Experiments 1 and 2 measured number-word knowledge and general vocabulary in a total of 59 children, ages 30-60 months. A strong correlation was found between number-word knowledge and vocabulary, independent of the child's age, contrary to previous results (D. Ansari et al., 2003). This result calls into question arguments that (a) the number-concept creation process is scaffolded mainly by visuo-spatial development and (b) that language only becomes integrated after the concepts are created (D. Ansari et al., 2003). Instead, this may suggest that having a larger nominal vocabulary helps children learn number words. Experiment 3 shows that the differences with previous results are likely due to changes in how the data were analyzed. © 2012 The Authors.

    Today, social media is increasingly used by patients to openly discuss their health. Mining automatically such data is a challenging task because of the non-structured nature of the text and the use of many abbreviations and the slang terms. Our goal is to use Patient Authored Text to build a French Consumer Health Vocabulary on breast cancer field, by collecting various kinds of non-experts' expressions that are related to their diseases and then compare them to biomedical terms used by health care professionals. We combine several methods of the literature based on linguistic and statistical approaches to extract candidate terms used by non-experts and to link them to expert terms. We use messages extracted from the forum on ' cancerdusein.org ' and a vocabulary dedicated to breast cancer elaborated by the Institut National Du Cancer. We have built an efficient vocabulary composed of 192 validated relationships and formalized in Simple Knowledge Organization System ontology.

    Full Text Available The current study sought to increase our understanding of the factors involved in the early vocabulary development of Australian Indigenous children. Data from the Longitudinal Study of Indigenous Children were available for 573 Indigenous children (291 boys who spoke English (M=37.0 months, SD=5.4 months, at wave 3. Data were also available for 86 children (51 boys who spoke an Indigenous language (M=37.1 months, SD=6.0 months, at wave 3. As hypothesised, higher levels of parent-child book reading and having more children’s books in the home were associated with better English vocabulary development. Oral storytelling in Indigenous language was a significant predictor of the size of children’s Indigenous vocabulary.

    2015-01-01

    Full Text Available This paper presents an adaptation of the MacArthur-Bates Communicative Development Inventories (short version into three languages spoken in Southern Mozambique. The tool was adapted to study vocabulary development among children of 12 to 25 months of age in two communities: a rural, monolingual Changana speaking community and an urban bilingual Ronga and Portuguese speaking community. We present a norming study carried out with the adaptation, as well as a validation study. The norming study revealed various predictors for reported expressive and receptive vocabulary size. These predictors include age, socioeconomic status, reported health problems, caregiving practices, and location. The validation of the CDI among a small sample in both communities shows positive correlations between the reported expressive vocabulary scores and children’s recorded word production. We conclude that the adapted CDI is useful for research purposes and could be used as a template for adaptations into other languages from similar cultures.

  14. Mean deformation metrics for quantifying 3D cell–matrix interactions without requiring information about matrix material properties

    Mechanobiology relates cellular processes to mechanical signals, such as determining the effect of variations in matrix stiffness with cell tractions. Cell traction recorded via traction force microscopy (TFM) commonly takes place on materials such as polyacrylamide- and polyethylene glycol-based gels. Such experiments remain limited in physiological relevance because cells natively migrate within complex tissue microenvironments that are spatially heterogeneous and hierarchical. Yet, TFM requires determination of the matrix constitutive law (stress–strain relationship), which is not always readily available. In addition, the currently achievable displacement resolution limits the accuracy of TFM for relatively small cells. To overcome these limitations, and increase the physiological relevance of in vitro experimental design, we present a new approach and a set of associated biomechanical signatures that are based purely on measurements of the matrix's displacements without requiring any knowledge of its constitutive laws. We show that our mean deformation metrics (MDM) approach can provide significant biophysical information without the need to explicitly determine cell tractions. In the process of demonstrating the use of our MDM approach, we succeeded in expanding the capability of our displacement measurement technique such that it can now measure the 3D deformations around relatively small cells (∼10 micrometers), such as neutrophils. Furthermore, we also report previously unseen deformation patterns generated by motile neutrophils in 3D collagen gels. PMID:26929377

    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.

    In this article, we measure the effects of hypnosis and suggestions for learning second language vocabulary. Participants (N = 70) were randomly assigned to a hypnosis or a control group. They were pre-tested, and then presented 21 Spanish words, post-tested immediately and 1 week later. The data were analyzed using repeated measures analysis of variance with group (experimental versus control) as the between-subjects factor, and time as the within-subjects factor. The experimental group performed significantly better in both tests. Our results indicate that hypnosis is beneficial for second language vocabulary learning and retrieval.

    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.

    The US Rosetta Project has developed a program in Native American communities in which contemporary STEM vocabulary is taught alongside the same vocabulary in Navajo. NASA images and science are used and described in the native language, alongside both lay English, and scientific English. Additionally, science curriculum (geology/chemistry/botany/physics) elements drawn from the reservation environment, including geomorphology, geochemistry, soil physics, are included and discussed in the native language as much as possible — with their analogs in other planetary environments (such as Mars). The program began with a student defining 30 Navajo words to describe what he called 'NASA' words, such as: cell phone, astronaut, space suit, computer, and planets not visible to the naked eye. The use of NASA material and imagery have a positive impact on the accessibility of the overall STEM material but community involvement, and buy-in, is criti! cal to the success of the program. The US Rosetta Project modified its goals, and curriculum, to accommodate the programmatic desires of teachers in the district, and the capabilities of the medicine men that agreed to participate. In this presentation we will report on lessons learned, as well as metrics and successes associated with our most recent Summer Science Academy [2014].
