    Three experiments used the masked priming paradigm to investigate the role of orthographic and phonological information in written picture naming. In all the experiments, participants had to write the names of pictures as quickly as possible under three different priming conditions. Nonword primes could be: (1) phonologically and orthographically related to the picture name; (2) orthographically related as in (1) but phonologically related to a lesser degree than in (1); (3) orthographically and phonologically unrelated except for the first consonant (or consonant cluster). Orthographic priming effects were observed with a prime exposure duration of 34 ms (Experiments 1 and 2) and of 51 ms (Experiment 3). In none of the experiments, did homophony between primes and picture names yield an additional advantage. Taken together, these findings support the view of the direct retrieval of orthographic information through lexical access in written picture naming, and thus argue against the traditional view that the retrieval of orthographic codes of obligatorily mediated by phonology.

    Central to the current accounts of the word and the pseudoword superiority effect (WSE and PWSE, respectively) is the concept of a unitized code that is less susceptible to masking than single-letter codes. Current explanations of the WSE and PWSE assume that this unitized code is orthographic, explaining these phenomena by the assumption of dual read-out from unitized and single-letter codes. In this article, orthographic dual read-out models are compared with a phonological dual read-out model (which is based on the assumption that the 1st unitized code is phonological). From this phonological code, an orthographic code is derived, through either lexical access or assembly. Comparison of the orthographic and phonological dual read-out models was performed by formulating both models as multinomial processing tree models. From an application of these models to the data of 2 letter identification experiments, it was clear that the orthographic dual read-out models are insufficient as an explanation of the PWSE, whereas the phonological dual read-out model is sufficient.

  7. Code of conduct for scientists (abstract)

    International Nuclear Information System (INIS)

    The emergence of advanced technologies in the last three decades and extraordinary progress in our knowledge on the basic Physical, Chemical and Biological properties of living matter has offered tremendous benefits to human beings but simultaneously highlighted the need of higher awareness and responsibility by the scientists of 21 century. Scientist is not born with ethics, nor science is ethically neutral, but there are ethical dimensions to scientific work. There is need to evolve an appropriate Code of Conduct for scientist particularly working in every field of Science. However, while considering the contents, promulgation and adaptation of Codes of Conduct for Scientists, a balance is needed to be maintained between freedom of scientists and at the same time some binding on them in the form of Code of Conducts. The use of good and safe laboratory procedures, whether, codified by law or by common practice must also be considered as part of the moral duties of scientists. It is internationally agreed that a general Code of Conduct can't be formulated for all the scientists universally, but there should be a set of 'building blocks' aimed at establishing the Code of Conduct for Scientists either as individual researcher or responsible for direction, evaluation, monitoring of scientific activities at the institutional or organizational level.

    A reversible abstract machine architecture and its reversible machine code are presented and formalized. For machine code to be reversible, both the underlying control logic and each instruction must be reversible. A general class of machine instruction sets was proven to be reversible, building ...... on our concept of reversible updates. The presentation is abstract and can serve as a guideline for a family of reversible processor designs. By example, we illustrate programming principles for the abstract machine architecture formalized in this paper....

  9. Creating abstract topographic representations: implications for coding, learning and reasoning.

    Topographic maps are a fundamental and ubiquitous feature of the sensory and motor regions of the brain. There is less evidence for the existence of conventional topographic maps in associational areas of the brain such as the prefrontal cortex and parietal cortex. The existence of topographically arranged anatomical projections is far more widespread and occurs in associational regions of the brain as well as sensory and motor regions: this points to a more widespread existence of topographically organised maps within associational cortex than currently recognised. Indeed, there is increasing evidence that abstract topographic representations may also occur in these regions. For example, a topographic mnemonic map of visual space has been described in the dorsolateral prefrontal cortex and topographically arranged visuospatial attentional signals have been described in parietal association cortex. This article explores how abstract representations might be extracted from sensory topographic representations and subsequently code abstract information. Finally a simple model is presented that shows how abstract topographic representations could be integrated with other information within the brain to solve problems or form abstract associations. The model uses correlative firing to detect associations between different types of stimuli. It is flexible because it can produce correlations between information represented in a topographic or non-topographic coordinate system. It is proposed that a similar process could be used in high-level cognitive operations such as learning and reasoning.

    The design of the communication protocols in wireless sensor networks (WSNs) often neglects several key characteristics of the sensor's hardware, while assuming that the number of transmitted bits is the dominating factor behind the system's energy consumption. A closer look at the hardware...... specifications of common sensors reveals, however, that other equally important culprits exist, such as the reception and processing energy. Hence, there is a need for a more complete hardware abstraction of a sensor node to reduce effectively the total energy consumption of the network by designing energy...... platforms, the use of relays may decrease up to 4.5 times the total energy consumption when the protocol and the hardware are carefully matched. We conclude that: 1) the energy budget for a communication protocol varies significantly on different sensor platforms; and 2) the protocols can be judiciously...

    1.Influence of Formulating Code of Conduct in the South China Sea on China" s Defending, of its Rights and How to Deal with It,by Dr. Jiang Guoxue, a research fellow at the Center for Development Studies of the Asia Pacific Region in Guangzhou, Guangdong Province, and Dr. Lin Lanzhao, an associate researcher at the same center. In recent years, some countries concerned in the ASEAN, for the sake of restricting ChinaI s action and ensuring their vested interests, have made every effort to push forward with the formulation and signing of code of conduct as soon as possible. To sign and pass the Code of Conduct in the South China Sea is not conductive to China to protect its rights and interests in the South China Sea at present, however, it can win China time and space for the final solution of the issue. We should actively participate in and play a leading role in the process of the formulation of that code of conduct. In the meantime, we should speed up our resources development and tighten controls over those islands, reefs and adjacent waters in the South China Sea, and endeavor to enhance our comprehensive national strength, thus laying a solid foundation for the comprehensive and thorough settlement of the South China Sea issue.

    --Based on of Marx's Economic Philosophy Manuscripts of 1844 HE Jian-jin (Philosophy Department, Fujian Provincial Committee Party School, Fuzhou, Fujian 350012, China) Abstract: Socialism with Chinese characteristics has a close relationship with the return and growth of capital in China. To implement the scientific concept of development, we must confront the problem of scientifically controlling the capital. In Economic and Philosophical Manuscripts of 1844, Marx criticized the three old philosophical thinking of treating capital: Object-oriented thinking, intuitive thinking, purely spiritual abstract thinking, and he established his own unique understanding of the capital that is to understand the capital from the human perceptual activities and practical activities. Contemporary Chinese society exist the problem of underdevelopment and abnormal development, and the three heterogeneity problems of pre-modern, modern, postmodern concurrent. In order to implement the scientific concept of development, we must reject any abstract positive or negative to modern basic principles under the guidance of the capital, against the eternal capital theory and capital theory of evil, and we must oppose the thinking that the capital is eternal or evil. Key words: socialism with Chinese characteristics; capital; national economics; scientific concept of development

    Spiritual Construction and Its Ideological Sources in Contemporary China The spiritual construction in contemporary China is an important ideological task proposed by the historical practice of China. Modernized development often entails the meaning of entering into " modern civilization. " Nevertheless, an abstract understanding of this civilization has covered up its essential stipulation and historical nature. China has pursued its development on a different historical prerequisite from the west, and therefore, only partially belongs to modern capitalist modernization. The practical prospects of Chinese development imply a transformation and remodeling of the general lifestyle, life attitudes and values, which inevitably calls for a new form of philosophy. The ideological sources for this new philosophy are: Chinese philosophy, Western integration of them may point to philosophy and Marxist philosophy.

After those disasters, the government had made some progress by a series of measures like repairing the dike, completing water conservancy institutions and enacting regulations in order to strengthen the water conservancy construction in Hubei. The government took water conservancy construction as a complex system project so that they had a relatively comprehensive consideration. It reflects the advancement of modern government to mobilize local people and put such social power into the unified planning. However, thelimitations of the government's policy implementation weakened the effect of water conservancy construction. Keywords: flood; government; water conservancy construction; effect

    On Rousseau's Equality and Freedom GONG Qun Abstract:Equality and freedom are the two core concepts of political philosophy and Rousseau~s political philosophy is no exception. Freedom and equality in Rousseau in- cludes two levels: natural state and social state under social contract, and among them, there is one state of un-equality. The relationship between the two concepts here is that equality is a necessary precondition of freedom, and that there is no equality, there is no freedom. The achievement of Rousseau~s equality is by one contractual behavior that all the members transfer their rights, especially property rights, and form of the Community. Freedom in Rousseau's mind is through the people's sovereignty in the Community to achieve freedom.

    [Abstract] The essay analyzed the action logic of hegemon with a power approach. Hegemony can be classified as benign or malignant. A benign hegemon should be pro- ductive, inclusive and maintain procedure justice when it uses its power. The power of hegemon can be categorized into two types: the hard power, which is the use of coer- cion and payment and can be measured by public products, and the soft power, which shows the ability to attract and co-opt and can be measured by the relationship-specific investments. The relationship between the input of public products and the relationship -specific investments is not positively correlative. Confusing with the public products and the soft power might lead to strategic misleading. A country rich in power re- sources should comply with the following principles if it wanted to improve its hard power and soft power: first, analyze the scope of the existing hegemon's soft power and avoid investing public products in the scope; second, maintain honesty in a long term and continue to increase others' benefits following the rule of neutral Pareto im- provement; third, provide both public goods and public bads; fourth, be more patient to obtain soft power.

    The Western Characteristics of the Pardims of International Studies in America:With the Huaxla System as a Counterexample Ye Zicheng (4)[ Abstract ] Three flaws are obvious in the three paradigms of International Studies in America. Specifically, their arguments are based on the assumption that the world is anarchic ; they go too far in employing the scientific and rational methodology; they pay little attention to the humans. Hence, the three paradigms of international studies in America aren' t necessarily useful for the explanation of China' s history and culture as well as its relations with the outside world. The Huaxia system, for example, is anarchic but also apparently hierarchical; the approach of pursuing security in understanding the rise of western powers may be meaningless, for the hegemony in the Huaxia System needn't worry about its security; the theory of power-balancing seemingly couldn' t explain why Qin ended up in defeating the alliance of the other six states in the Warring-states period. The Huaxia system is quite open, and has free movement of people, goods, and ideas. Some interstate regimes and institutions were formed through Huimeng (alliance-making) among states. However, this kind of limited and fragile interdependence and cooperation soon came to an end after the hegemonies of Qi, Jin and Wei. There does exit the identity problem among states in the Huaxia System, but this problem doesn't play such a great role as the constructivists expect it would.

    Strategic Realism: An Option for China' s Grand Strategy Song Dexing (4) [ Abstract] As a non-Western emerging power, China should positively adapt its grand strategy to the strategic psychological traits in the 21st century, maintain a realist tone consistent with the national conditions of China, and avoid adventurist policies while awaring both strategic strength and weakness. In the 21st century, China' s grand strategy should be based on such core values as security, development, peace and justice, especially focusing on development in particular, which we named "strategic realism". Given the profound changes in China and the world, strategic realism encourages active foreign policy to safe- guard the long-term national interests of China. Following the self-help logic and the fun- damental values of security and prosperity, strategic realism concerns national interests as its top-priority. It advocates smart use of power, and aims to achieve its objectives by optimizing both domestic and international conditions. From the perspective of diplomatic phi- losophy, strategic realism is not a summarization of concrete policies but a description of China' s grand strategy orientations in the new century.

    The term ''code package'' is used to describe a miscellaneous grouping of materials which, when interpreted in connection with a digital computer, enables the scientist--user to solve technical problems in the area for which the material was designed. In general, a ''code package'' consists of written material--reports, instructions, flow charts, listings of data, and other useful material and IBM card decks (or, more often, a reel of magnetic tape) on which the source decks, sample problem input (including libraries of data) and the BCD/EBCDIC output listing from the sample problem are written. In addition to the main code, and any available auxiliary routines are also included. The abstract format was chosen to give to a potential code user several criteria for deciding whether or not he wishes to request the code package

  10. A Global View Programming Abstraction for Transitioning MPI Codes to PGAS Languages

    The multicore generation of scientific high performance computing has provided a platform for the realization of Exascale computing, and has also underscored the need for new paradigms in coding parallel applications. The current standard for writing parallel applications requires programmers to use languages designed for sequential execution. These languages have abstractions that only allow programmers to operate on the process centric local view of data. To provide suitable languages for parallel execution, many research efforts have designed languages based on the Partitioned Global Address Space (PGAS) programming model. Chapel is one of the more recent languages to be developed using this model. Chapel supports multithreaded execution with high-level abstractions for parallelism. With Chapel in mind, we have developed a set of directives that serve as intermediate expressions for transitioning scientific applications from languages designed for sequential execution to PGAS languages like Chapel that are being developed with parallelism in mind.

    Full Text Available Simulations with multi-physics modeling have become crucial to many science and engineering fields, and multi-physics capable scientific software is as important to these fields as instruments and facilities are to experimental sciences. The current generation of mature multi-physics codes would have sustainably served their target communities with modest amount of ongoing investment for enhancing capabilities. However, the revolution occurring in the hardware architecture has made it necessary to tackle the parallelism and performance management in these codes at multiple levels. The requirements of various levels are often at cross-purposes with one another, and therefore hugely complicate the software design. All of these considerations make it essential to approach this challenge cooperatively as a community. We conducted a series of workshops under an NSF-SI2 conceptualization grant to get input from various stakeholders, and to identify broad approaches that might lead to a solution. In this position paper we detail the major concerns articulated by the application code developers, and emerging trends in utilization of programming abstractions that we found through these workshops.

  12. Orthographic familiarity, phonological legality and number of orthographic neighbours affect the onset of ERP lexical effects

    2008-07-01

    Full Text Available Abstract Background It has been suggested that the variability among studies in the onset of lexical effects may be due to a series of methodological differences. In this study we investigated the role of orthographic familiarity, phonological legality and number of orthographic neighbours of words in determining the onset of word/non-word discriminative responses. Methods ERPs were recorded from 128 sites in 16 Italian University students engaged in a lexical decision task. Stimuli were 100 words, 100 quasi-words (obtained by the replacement of a single letter, 100 pseudo-words (non-derived and 100 illegal letter strings. All stimuli were balanced for length; words and quasi-words were also balanced for frequency of use, domain of semantic category and imageability. SwLORETA source reconstruction was performed on ERP difference waves of interest. Results Overall, the data provided evidence that the latency of lexical effects (word/non-word discrimination varied as a function of the number of a word's orthographic neighbours, being shorter to non-derived than to derived pseudo-words. This suggests some caveats about the use in lexical decision paradigms of quasi-words obtained by transposing or replacing only 1 or 2 letters. Our findings also showed that the left-occipito/temporal area, reflecting the activity of the left fusiform gyrus (BA37 of the temporal lobe, was affected by the visual familiarity of words, thus explaining its lexical sensitivity (word vs. non-word discrimination. The temporo-parietal area was markedly sensitive to phonological legality exhibiting a clear-cut discriminative response between illegal and legal strings as early as 250 ms of latency. Conclusion The onset of lexical effects in a lexical decision paradigm depends on a series of factors, including orthographic familiarity, degree of global lexical activity, and phonologic legality of non-words.

  14. A new magnetic bar code system based on a magnetic anisotropy detection (abstract)

    Magnetic bar codes can be used in unclean environments, where widely used optical bar code systems cannot be applied. Readout system for magnetic bar codes can also be made much simpler than optical ones. A new magnetic bar code system is proposed, in which binary information is coded in the sign of tilted angles of magnetic strips from a given standard direction. This scheme is unique compared to the conventional optical bar code, where width or space of the parallel pattern carries information, or an already reported magnetic bar code, where cross sectional shapes of pattern engraved in a ferromagnetic body carries information. Each of the magnetic strips brings about magnetic anisotropy due to its shape effect, hence angular dependent permeability in the proximity of the strip. The sign of the tilted angle of each magnetic strip is detected inductively through the angular dependent permeability by using a magnetic pickup head with a pair of cross-coupled figure-eight coils, where the sign of mutual inductance between the primary and the secondary figure-eight coil has one to one relationship to the sign of the tilted angle. Because the detection of the tilted angle is independent of scanning speed, variation in the scanning speed of the readout head does not affect the performance. In our preliminary study, the proposed magnetic bar code system was examined using pickup head consisting of a pair of cross-coupled 10-turn figure-eight coils which was embedded in a rectangular ferrite rod with cross-shape groove on the top surface of 6.5×3 mm dimension. The head was made thinner in the scanning direction to allow dense alignment of the pattern. Two kinds of pattern were made: the one was by aligning short amorphous wires (5 mm in length and 120 μm in diameter) on the plastic film and the other by using a thin (10 μm in thickness) copper film with tilted slits backed by an amorphous ribbon. These samples of magnetic bar code patterns were scanned with lift-off of

  16. A dual-route approach to orthographic processing

    2011-04-01

    Full Text Available In the present theoretical note we examine how different learning constraints, thought to be involved in optimizing the mapping of print to meaning during reading acquisition, might shape the nature of the orthographic code involved in skilled reading. On the one hand, optimization is hypothesized to involve selecting combinations of letters that are the most informative with respect to word identity (diagnosticity constraint, and on the other hand to involve the detection of letter combinations that correspond to pre-existing sublexical phonological and morphological representations (chunking constraint. These two constraints give rise to two different kinds of prelexical orthographic code, a coarse-grained and a fine-grained code, associated with the two routes of a dual-route architecture. Processing along the coarse-grained route optimizes fast access to semantics by using minimal subsets of letters that maximize information with respect to word identity, while coding for approximate within-word letter position independently of letter contiguity. Processing along the fined-grained route, on the other hand, is sensitive to the precise ordering of letters, as well as to position with respect to word beginnings and endings. This enables the chunking of frequently co-occurring contiguous letter combinations that form relevant units for morpho-orthographic processing (prefixes and suffixes and for the sublexical translation of print to sound (multi-letter graphemes.

    Behavioral control is influenced not only by learning from the choices made and the rewards obtained but also by "what might have happened," that is, inference about unchosen options and their fictive outcomes. Substantial progress has been made in understanding the neural signatures of direct learning from choices that are actually made and their associated rewards via reward prediction errors (RPEs). However, electrophysiological correlates of abstract inference in decision-making are less clear. One seminal theory suggests that the so-called feedback-related negativity (FRN), an ERP peaking 200-300 msec after a feedback stimulus at frontocentral sites of the scalp, codes RPEs. Hitherto, the FRN has been predominantly related to a so-called "model-free" RPE: The difference between the observed outcome and what had been expected. Here, by means of computational modeling of choice behavior, we show that individuals employ abstract, "double-update" inference on the task structure by concurrently tracking values of chosen stimuli (associated with observed outcomes) and unchosen stimuli (linked to fictive outcomes). In a parametric analysis, model-free RPEs as well as their modification because of abstract inference were regressed against single-trial FRN amplitudes. We demonstrate that components related to abstract inference uniquely explain variance in the FRN beyond model-free RPEs. These findings advance our understanding of the FRN and its role in behavioral adaptation. This might further the investigation of disturbed abstract inference, as proposed, for example, for psychiatric disorders, and its underlying neural correlates. PMID:27031567

  18. Abstracts of digital computer code packages assembled by the Radiation Shielding Information Center

    International Nuclear Information System (INIS)

    This publication, ORNL/RSIC-13, Volumes I to III Revised, has resulted from an internal audit of the first 168 packages of computing technology in the Computer Codes Collection (CCC) of the Radiation Shielding Information Center (RSIC). It replaces the earlier three documents published as single volumes between 1966 to 1972. A significant number of the early code packages were considered to be obsolete and were removed from the collection in the audit process and the CCC numbers were not reassigned. Others not currently being used by the nuclear R and D community were retained in the collection to preserve technology not replaced by newer methods, or were considered of potential value for reference purposes. Much of the early technology, however, has improved through developer/RSIC/user interaction and continues at the forefront of the advancing state-of-the-art

    French children program the words they write syllable by syllable. We examined whether the syllable the children use to segment words is determined phonologically (i.e., is derived from speech production processes) or orthographically. Third, 4th and 5th graders wrote on a digitiser words that were mono-syllables phonologically (e.g. barque=[baRk]) but bi-syllables orthographically (e.g. barque=bar.que). These words were matched to words that were bi-syllables both phonologically and orthographically (e.g. balcon=[bal.kõ] and bal.con). The results on letter stroke duration and fluency yielded significant peaks at the syllable boundary for both types of words, indicating that the children use orthographic rather than phonological syllables as processing units to program the words they write.

    Full Text Available Previous studies have found that children with reading difficulties need more exposures to acquire the representations needed to support fluent reading than typically developing readers (e.g., Ehri & Saltmarsh, 1995. Building on existing orthographic learning paradigms, we report on an investigation of orthographic learning in poor readers using a new learning task tracking both the accuracy (untimed exposure duration and fluency (200ms exposure duration of learning novel words over trials. In study 1, we used the paradigm to examine orthographic learning in children with specific poor reader profiles (9 with a surface profile, 9 a phonological profile and 9 age-matched controls. Both profiles showed improvement over the learning cycles, but the children with surface profile showed impaired orthographic learning in spelling and orthographic choice tasks. Study 2 explored predictors of orthographic learning in a group of 91 poor readers using the same outcome measures as in Study 1. Consistent with earlier findings in typically developing readers, phonological decoding skill predicted orthographic learning. Moreover, orthographic knowledge significantly predicted orthographic learning over and beyond phonological decoding. The two studies provide insights into how poor readers learn novel words, and how their learning process may be compromised by less proficient orthographic and/or phonological skills.

    First, these results reveal a neurotopography of OWM lesion sites that is well-aligned with results from neuroimaging of orthographic working memory in neurally intact participants (Rapp & Dufor, 2011. Second, the dorsal neurotopography of the OWM lesion overlap is clearly distinct from what has been reported for lesions associated with either lexical or sublexical deficits (e.g., Henry, Beeson, Stark, & Rapcsak, 2007; Rapcsak & Beeson, 2004; these have, respectively, been identified with the inferior occipital/temporal and superior temporal/inferior parietal regions. These neurotopographic distinctions support the claims of the computational distinctiveness of long-term vs. working memory operations. The specific lesion loci raise a number of questions to be discussed regarding: (a the selectivity of these regions and associated deficits to orthographic working memory vs. working memory more generally (b the possibility that different lesion sub-regions may correspond to different components of the OWM system.

  3. A test of the orthographic recoding hypothesis

    2003-04-01

    The Orthographic Recoding Hypothesis [D. E. Gaygen and P. A. Luce, Percept. Psychophys. 60, 465-483 (1998)] was tested. According to this hypothesis, listeners recognize spoken words heard for the first time by mapping them onto stored representations of the orthographic forms of the words. Listeners have a stable orthographic representation of words, but no phonological representation, when those words have been read frequently but never heard or spoken. Such may be the case for low frequency words such as jargon. Three experiments using visually and auditorily presented nonword stimuli tested this hypothesis. The first two experiments were explicit tests of memory (old-new tests) for words presented visually. In the first experiment, the recognition of auditorily presented nonwords was facilitated when they previously appeared on a visually presented list. The second experiment was similar, but included a concurrent articulation task during a visual word list presentation, thus preventing covert rehearsal of the nonwords. The results were similar to the first experiment. The third experiment was an indirect test of memory (auditory lexical decision task) for visually presented nonwords. Auditorily presented nonwords were identified as nonwords significantly more slowly if they had previously appeared on the visually presented list accompanied by a concurrent articulation task.

    Wang, Hua-Chen; Nickels, Lyndsey; Castles, Anne

    2015-01-01

    Phonological decoding skill has been proposed to be key to successful sight word learning (orthographic learning). However, little is known about how children with phonological dyslexia, who have impaired phonological decoding, acquire sight words, or why children with surface dyslexia can have normal phonological decoding skill yet impaired sight word acquisition. This study addressed this issue by investigating orthographic learning in two 10-year-old children: S.D., with a reading profile of surface dyslexia, and P.D., with a reading profile of phonological dyslexia. They participated in two experiments exploring the role of phonological decoding and paired-associate learning in orthographic learning. The results showed that, first, P.D.'s orthographic learning ability was better than S.D.'s, despite her phonological decoding skills being poorer. Second, S.D. showed impaired paired-associate learning abilities while P.D. did not. Overall, the results indicate that phonological decoding ability does not translate directly to orthographic learning ability, and that paired-associate learning ability may also be associated with success in orthographic learning.

  20. Lexical orthographic acquisition: Is handwriting better than spelling aloud?

    Directory of Open Access Journals (Sweden)

    Marie-Line eBosse

    2014-02-01

    Full Text Available Lexical orthography acquisition is currently described as the building of links between the visual forms and the auditory forms of whole words. However, a growing body of data suggests that a motor component could further be involved in orthographic acquisition. A few studies support the idea that reading plus handwriting is a better lexical orthographic learning situation than reading alone. However, these studies did not explore which of the cognitive processes involved in handwriting enhanced lexical orthographic acquisition. Some findings suggest that the specific movements memorized when learning to write may participate in the establishment of orthographic representations in memory. The aim of the present study was to assess this hypothesis using handwriting and spelling aloud as two learning conditions. In two experiments, fifth graders were asked to read complex pseudo-words embedded in short sentences. Immediately after reading, participants had to recall the pseudo-words’ spellings either by spelling them aloud or by handwriting them down. One week later, orthographic acquisition was tested using two post-tests: a pseudo-word production task (spelling by hand in Experiment 1 or spelling aloud in Experiment 2 and a pseudo-word recognition task. Results showed no significant difference in pseudo-word recognition between the two learning conditions. In the pseudo-word production task, orthography learning improved when the learning and post-test conditions were similar, thus showing a massive encoding-retrieval match effect in the two experiments. However, a mixed model analysis of the pseudo-word production results revealed a significant learning condition effect which remained after control of the encoding-retrieval match effect. This later finding suggests that orthography learning is more efficient when mediated by handwriting than by spelling aloud, whatever the post-test production task.

    2001-09-01

    Children's (Grades 1 to 5) implicit learning of French orthographic regularities was investigated through nonword judgment (Experiments 1 and 2) and completion (Experiments 3a and 3b) tasks. Children were increasingly sensitive to (a) the frequency of double consonants (Experiments 1, 2, and 3a), (b) the fact that vowels can never be doubled (Experiment 2), and (c) the legal position of double consonants (Experiments 2 and 3b). The latter effect transferred to never doubled consonants but with a decrement in performance. Moreover, this decrement persisted without any trend toward fading, even after the massive amounts of experience provided by years of practice. This result runs against the idea that transfer to novel material is indicative of abstract rule-based knowledge and suggests instead the action of mechanisms sensitive to the statistical properties of the material. A connectionist model is proposed as an instantiation of such mechanisms. PMID:11561917

    2016-05-01

    The current study was designed to test how orthographic learning, or the learning of the spelling patterns of words, happens within the self-teaching paradigm. One possibility is that orthographic learning occurs on a word-specific basis. Two other possibilities are that orthographic learning transfers specifically to the processing of novel words that are morphologically related or that it transfers to novel words that are orthographically similar, regardless of morphological relationship. In an orthographic learning paradigm, we asked children in Grades 3 and 5 to read nonwords embedded in short stories. In a between-participants design, some children read nonwords that were base forms, others read nonwords that were morphologically complex forms, and others read nonwords that were orthographically complex forms (e.g., feap, feaper, and feaple, respectively). Children completed an orthographic choice task with the same items as in the stories. To evaluate transfer of learning, children also completed orthographic choices for the two forms of the nonwords not seen in the stories. Results indicated that children's orthographic learning affected processing of novel items that appeared to be morphologically related as well as those that shared only orthographic structure (e.g., both feaper and feaple). Additional analyses showed that these effects were held across cases when children did and did not successfully decode the novel words in the learning experience, although successful decoding did lead to higher levels of orthographic learning and transfer. Together, the findings suggest that children's prior experiences affect their processing of novel words that share orthographic similarity, likely reflecting a role for orthographic analogies in the self-teaching process.

    The Three - Stage Interaction Model of Lexicon - Syntax Interface Liu Yuhong (80) The Three -Stage Interaction Model maintains that the interactions at the lexicon -syntax interface are divisible into three levels, namely, the interaction between lexical meaning and lexical grammar that determines syntactic items, the interaction among lexical items that determines syntactic structure, and the interaction between abstract syntactic structure (i. e. construction) and temporary syntactic combinations that determines and coerces grammaticality of the latter. The Three - Stage Interaction Model is hierarchical, complete and bidirectional in language comprehension. It also testifies to the varying abstractness between grammar (syntax) and semantics, and between the five grammatical cases. According to this model, temporary syntactic combination is sanctioned by abstract syntactic structure, therefore the conventional linguistic significance of P600 is maintained without coining contradictory new terms.

    Full Text Available Orthographic depth (i.e., the complexity, consistency, or transparency of grapheme-phoneme correspondences in written alphabetic language plays an important role in the acquisition of reading skills. Correspondingly, developmental dyslexia is characterized by different behavioral manifestations across languages varying in orthographic depth. This review focuses on the question of whether these different behavioral manifestations are associated with different functional neuroanatomical manifestations. It provides a review and critique of cross-linguistic brain imaging studies of developmental dyslexia. In addition, it includes an analysis of state-of-the-art functional neuroanatomical models of developmental dyslexia together with orthography-specific predictions derived from these models. These predictions should be tested in future brain imaging studies of typical and atypical reading in order to refine the current neurobiological understanding of developmental dyslexia, especially with respect to orthography-specific and universal aspects.

  7. Reconstructing Wireframe Model of Curvilinear Objects from Three Orthographic Views

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    An approach for reconstructing wireframe models of curvilinear objects from three orthographic views is discussed in this paper. The method for generating 3D conic edges from 2D projection conic curves is emphasized especially, which is the pivotal work for reconstructing curvilinear objects from three orthographic views. In order to generate 3D conic edges, a five-point method is firstly utilized to obtain the algebraic representations of all 2D-projection curves in each view, and then all algebraic forms are converted to the corresponding geometric forms analytically. Thus the locus of a 3D conic edge can be derived from the geometric forms of the relevant conic curves in three views. Finally, the wireframe model is created after eliminating all redundant elements generated in previous reconstruction process. The approach extends the range of objects to be reconstructed and imposes no restriction on the axis of the quadric surface.

    The contribution of orthographic representations to reading and writing has been intensively investigated in the literature. However, the distinction between neuronal correlates of the orthographic lexicon and the orthographic (graphemic) buffer has rarely been examined in alphabetic languages and never been explored in non-alphabetic languages. To determine whether the neural networks associated with the orthographic lexicon and buffer of logographic materials are comparable to those reported in the literature, the present fMRI experiment manipulated frequency and the stroke number of Chinese characters in the tasks of form judgment and stroke judgment, which emphasized the processing of character recognition and writing, respectively. It was found that the left fusiform gyrus exhibited higher activation when encountering low-frequency than high-frequency characters in both tasks, which suggested this region to be the locus of the orthographic lexicon that represents the knowledge of character forms. On the other hand, the activations in the posterior part of the left middle frontal gyrus and in the left angular gyrus were parametrically modulated by the stroke number of target characters only in the stroke judgment task, which suggested these regions to be the locus of the orthographic buffer that represents the processing of stroke sequence in writing. These results provide the first evidence for the functional and anatomical dissociation between the orthographic lexicon and buffer in reading and writing Chinese characters. They also demonstrate the critical roles of the left fusiform area and the frontoparietal network to the long-term and short-term representations of orthographic knowledge, respectively, across different orthographies.

    2016-08-01

    We present a new method of synthesizing a digital hologram of three-dimensional (3D) real-world objects from multiple orthographic projection images (OPI). A high-resolution multiple perspectives of 3D objects (i.e., two dimensional elemental image array) are captured under incoherent white light using synthetic aperture integral imaging (SAII) technique and their OPIs are obtained respectively. The reference beam is then multiplied with the corresponding OPI and integrated to form a Fourier hologram. Eventually, a modified phase retrieval algorithm (GS/HIO) is applied to reconstruct the hologram. The principle is validated experimentally and the results support the feasibility of the proposed method.

    This study reports two experiments assessing the spelling performance of French first graders after 3 months and after 9 months of literacy instruction. The participants were asked to spell high and low frequency irregular words (Experiment 1) and pseudowords, some of which had lexical neighbours (Experiment 2). The lexical database which children had been exposed to was strictly controlled. Both a frequency effect in word spelling accuracy and an analogy effect in pseudoword spelling were obtained after only 3 months of reading instruction. The results suggest that children establish specific orthographic knowledge from the very beginning of literacy acquisition. PMID:14738774

  17. Visual, orthographic, phonological, and lexical influences in reading.

    1994-12-01

    The fuzzy logical model of perception (FLMP), used as a framework to analyze phenomena in reading, asserts that there are multiple influences on reading performance. Experiments on the dynamic interaction of letter information and orthographic context are presented. Previous results have supported the FLMP over a variety of interactive activation models. These findings indicated that lateral masking and the time course of processing must be accounted for in the theoretical prediction of letter and word recognition. A new finding is that the word superiority effect is not influenced by the nature of the backward masking stimulus, nor is it diminished with letter and word masks, contrary to the predictions of several extant explanations. The FLMP is extended to account for reaction time in reading. Perceptual recognition, naming, and lexical decision tasks reflect the influence of multiple sources of information. These include orthographic structure, spelling-to-speech correspondences, and word frequency. Reading can be productively analyzed as a prototypical pattern recognition situation in which the reader exploits multiple sources of information in perception and action. PMID:7844509

  18. INF Code related matters. Joint IAEA/IMO literature survey on potential consequences of severe maritime accidents involving the transport of radioactive material. 2 volumes. Vol. I - Report and publication titles. Vol. II - Relevant abstracts

    International Nuclear Information System (INIS)

    This literature survey was undertaken jointly by the International Maritime Organization (IMO) and the International Atomic Energy Agency (IAEA) as a step in addressing the subject of environmental impact of accidents involving materials subject to the IMO's Code for the Safe Carriage of Irradiated Nuclear Fuel, Plutonium and High-Level Radioactive Wastes in Flasks on Board Ships, also known as the INF Code. The results of the survey are provided in two volumes: the first one containing the description of the search and search results with the list of generated publication titles, and the second volume containing the abstracts of those publications deemed relevant for the purposes of the literature survey. Literature published between 1980 and mid-1999 was reviewed by two independent consultants who generated publication titles by performing searches of appropriate databases, and selected the abstracts of relevant publications for inclusion in this survey. The IAEA operates INIS, the world's leading computerised bibliographical information system on the peaceful uses of nuclear energy. The acronym INIS stands for International Nuclear Information System. INIS Members are responsible for determining the relevant nuclear literature produced within their borders or organizational confines, and then preparing the associated input in accordance with INIS rules. INIS records are included in other major databases such as the Energy, Science and Technology database of the DIALOG service. Because it is the INIS Members, rather than the IAEA Secretariat, who are responsible for its contents, it was considered appropriate that INIS be the primary source of information for this literature review. Selected unpublished reports were also reviewed, e.g. Draft Proceedings of the Special Consultative Meeting of Entities involved in the maritime transport of materials covered by the INF Code (SCM 5), March 1996. Many of the formal papers at SCM 5 were included in the literature

    The use of orthographic and phonological information in spoken word recognition was studied in a visual world task where L1 Finnish learners of L2 French (n = 64) and L1 French native speakers (n = 24) were asked to match spoken word forms with printed words while their eye movements were recorded. In Experiment 1, French target words were contrasted with competitors having a longer ( vs. ) or a shorter word initial phonological overlap ( vs. ) and an identical orthographic overlap. In Experiment 2, target words were contrasted with competitors of either longer ( vs. ) or shorter word initial orthographic overlap ( vs. ) and of an identical phonological overlap. A general phonological effect was observed in the L2 listener group but not in the L1 control group. No general orthographic effects were observed in the L2 or L1 groups, but a significant effect of proficiency was observed for orthographic overlap over time: higher proficiency L2 listeners used also orthographic information in the matching task in a time-window from 400 to 700 ms, whereas no such effect was observed for lower proficiency listeners. These results suggest that the activation of orthographic information in L2 spoken word recognition depends on proficiency in L2. PMID:27512381

    在软件同源性检测方法中,基于抽象语法树的比对方法能够有效地检测出基于代码全文拷贝、修改变量名、调整代码顺序等的抄袭手段,被广泛用于抄袭检测工具中。但基于抽象语法树的比对方法对于修改变量类型和添加无意义变量的抄袭手段束手无策。针对这种情况,提出了一种基于抽象语法树的改进思想,该思想通过剪去语法树中影响判断的叶子节点的手段来还原检测原文抄袭,能够达到有效检测修改变量类型和添加无意义变量等抄袭的目的。%Among the source code plagiarism detection algorithms used in software engineering, the algorithm based on abstract syntax tree (AST) can effectively detect those plagiarized cases of copying with no modiifcation, modifying variable names and changing the source code sequence, but the algorithm can not detect the cases of modifying the variable type, adding no useful variables and so on. In this paper, we propose an improved algorithm based on abstract syntax tree, which is implemented by cutting out the syntax tree leaf nodes that may affect the judgment. This improved algorithm can positively detect the plagiarism cases described in the previous.

    A perceptual frequency variant of the orthographic cue (OC) hypothesis (Peressotti, Cubelli, & Job, 2003) was tested in two perceptual identification experiments using the variable viewing position technique: German nouns and non-nouns that are most frequently perceived with or without initial letter capitalization, respectively, were tachistoscopically presented in upper-case, lower-case, or with initial capitalization. The results indicated that words were best recognized in the form they are most frequently perceived in, which suggests that during reading acquisition abstract as well as case- and item-specific OCs may be learned and used for recognition.

    Anagrams are used widely in psychological research. However, generating a range of strings with the same letter content is an inherently difficult and time-consuming task for humans, and current computer-based anagram generators do not provide the controls necessary for psychological research. In this article, we present a computational algorithm that overcomes these problems. Specifically, the algorithm processes automatically each word in a user-defined source vocabulary and outputs, for each word, all possible anagrams that exist as words (or as nonwords, if required) as defined by the same source vocabulary. Moreover, we show how the output of the algorithm can be filtered to produce anagrams within specific user-defined orthographic parameters. For example, the anagrams produced can be filtered to produce words that share, with each other or with other words in the source vocabulary, letters in only certain positions. Finally, we provide free access to the complete Windows-based program and source code containing these facilities for anagram generation.

    Previous studies have clearly demonstrated that the development of orthographic representations relies on phonological recoding. However, substantial questions persist about the remaining unexplained variance in the acquisition of word-specific orthographic knowledge that is still underspecified. The main aim of this study was to explore whether two cognitive factors-sensitivity to orthographic regularities and short-term memory (STM) for serial order-make independent contributions to the acquisition of novel orthographic representations beyond that of the phonological core component and the level of preexisting word-specific orthographic knowledge. To this end, we had children from second to sixth grades learn novel written word forms using a repeated spelling practice paradigm. The speed at which children learned the word forms and their long-term retention (1week and 1month later) were assessed. Hierarchical regression analyses revealed that phonological recoding, preexisting word-specific orthographic knowledge, and order STM explained a portion of the variance in orthographic learning speed, whereas phonological recoding, preexisting word-specific orthographic knowledge, and orthographic sensitivity each explained a portion of variance in the long-term retention of the newly created orthographic representations. A secondary aim of the study was to determine the developmental trajectory of the abilities to acquire novel orthographic word forms over the course of primary schooling. As expected, results showed an effect of age on both learning speed and long-term retention. The specific roles of orthographic sensitivity and order STM as independent factors involved in different steps of orthographic learning are discussed. PMID:26600080

    2015-01-01

    Underwater acoustic sensor networks (UASNs) are prone to packet loss due to their poor link condition with high noise and high bit error rate. Therefore, a fountain codes correlation chain abstraction based HARQ protocol (CCA-HARQ) is proposed for UASNs to guarantee the reliable message delivery. The CCA-HARQ protocol could feedback the decoding status of the receiver to the sender in a more detailed way by attaching the correlation chain abstraction information in the NACK message, with which the sender could make more intelligent decisions to conduct more effective retransmission coding packets and the transmission overhead as well as the end to end throughput performance are optimized as a result. On the basis, the proposed protocol is simulated on the platform of OPNET network simulators. Simulation results demonstrate that proposed CCA-HARQ plays better than traditional UW-HARQ protocol from the perspective of transmission overhead and the end to end throughput.%由于水声信道具有高噪声、高误比特率的特点,水声传感器网络链路可靠性非常差,很容易出现信息的丢失情况。为此,文章提出了一种基于喷泉码相关链提取的HARQ协议以解决水下不可靠传输问题的方法。协议通过在接收端提取译码状况的相关链信息并反馈,使得发送端能够根据反馈信息提供更有效的重传编码,从而降低了传输冗余,提高了端到端吞吐量。在此基础上,借助OPNET网络仿真平台对提出的协议进行仿真分析,论证了提出协议同现有的UW-HARQ协议相比,能够实现更好的吞吐量与传输冗余性能。

    2016-04-01

    This study examines whether orthographic information is used during prelexical processes in spoken word recognition by investigating ERPs during spoken word processing for Korean words. Differential effects due to orthographic syllable neighborhood size and sound-to-spelling consistency on P200 and N320 were evaluated by recording ERPs from 42 participants during a lexical decision task. The results indicate that P200 was smaller for words whose orthographic syllable neighbors are large in number rather than those that are small. In addition, a word with a large orthographic syllable neighborhood elicited a smaller N320 effect than a word with a small orthographic syllable neighborhood only when the word had inconsistent sound-to-spelling mapping. The results provide support for the assumption that orthographic information is used early during the prelexical spoken word recognition process. PMID:26669620

    Learning the structure of event sequences is a ubiquitous problem in cognition and particularly in language. One possible solution is to learn a probabilistic generative model of sequences that allows making predictions about upcoming events. Though appealing from a neurobiological standpoint, this approach is typically not pursued in connectionist modeling. Here, we investigated a sequential version of the restricted Boltzmann machine (RBM), a stochastic recurrent neural network that extracts high-order structure from sensory data through unsupervised generative learning and can encode contextual information in the form of internal, distributed representations. We assessed whether this type of network can extract the orthographic structure of English monosyllables by learning a generative model of the letter sequences forming a word training corpus. We show that the network learned an accurate probabilistic model of English graphotactics, which can be used to make predictions about the letter following a given context as well as to autonomously generate high-quality pseudowords. The model was compared to an extended version of simple recurrent networks, augmented with a stochastic process that allows autonomous generation of sequences, and to non-connectionist probabilistic models (n-grams and hidden Markov models). We conclude that sequential RBMs and stochastic simple recurrent networks are promising candidates for modeling cognition in the temporal domain. PMID:26073971

  9. The effect of decreased interletter spacing on orthographic processing.

    2015-06-01

    There is growing interest in how perceptual factors such as the spacing between letters within words modulate performance in visual word recognition and reading aloud. Extra-large letter spacing can strongly improve the reading performance of dyslexic children, and a small increase with respect to the standard spacing seems beneficial even for skilled word recognition in adult readers. In the present study we examined the effect of decreased letter spacing on perceptual identification and lexical decision tasks. Identification in the decreased spacing condition was slower than identification of normally spaced strings, thereby confirming that the reciprocal interference among letters located in close proximity (crowding) poses critical constraints on visual word processing. Importantly, the effect of spacing was not modulated by string length, suggesting that the locus of the spacing effect is at the level of letter detectors. Moreover, the processing of crowded letters was facilitated by top-down support from orthographic lexical representation as indicated by the fact that decreased spacing affected pseudowords significantly more than words. Conversely, in the lexical decision task only word responses were affected by the spacing manipulation. Overall, our findings support the hypothesis that increased crowding is particularly harmful for phonological decoding, thereby adversely affecting reading development in dyslexic children.

  10. An orthographic effect in phoneme processing, and its limitations

    2012-02-01

    Full Text Available To examine whether lexically stored knowledge about spelling influences phoneme evaluation, we conducted three experiments with a low-level phonetic judgement task: phoneme goodness rating. In each experiment, listeners heard phonetic tokens varying along a continuum centred on /s/, occurring finally in isolated word or nonword tokens. An effect of spelling appeared in Experiment 1: Native English speakers’ goodness ratings for the best /s/ tokens were significantly higher in words spelled with S (e.g., bless than in words spelled with C (e.g., voice. No such difference appeared when nonnative speakers rated the same materials in Experiment 2, indicating that the difference could not be due to acoustic characteristics of the S- versus C-words. In Experiment 3, nonwords with lexical neighbours consistently spelled with S (e.g., pless versus with C (e.g., floice failed to elicit orthographic neighbourhood effects; no significant difference appeared in native English speakers’ ratings for the S-consistent versus the C-consistent sets. Obligatory influence of lexical knowledge on phonemic processing would have predicted such neighbourhood effects; the findings are thus better accommodated by models in which phonemic decisions draw strategically upon lexical information.

  11. On Coding Non-Contiguous Letter Combinations

    Frédéric eDandurand

    2011-06-01

    Full Text Available Starting from the hypothesis that printed word identification initially involves the parallel mapping of visual features onto location-specific letter identities, we analyze the type of information that would be involved in optimally mapping this location-specific orthographic code onto a location-invariant lexical code. We assume that some intermediate level of coding exists between individual letters and whole words, and that this involves the representation of letter combinations. We then investigate the nature of this intermediate level of coding given the constraints of optimality. This intermediate level of coding is expected to compress data while retaining as much information as possible about word identity. Information conveyed by letters is a function of how much they constrain word identity and how visible they are. Optimization of this coding is a combination of minimizing resources (using the most compact representations and maximizing information. We show that in a large proportion of cases, non-contiguous letter sequences contain more information than contiguous sequences, while at the same time requiring less precise coding. Moreover, we found that the best predictor of human performance in orthographic priming experiments was within-word ranking of conditional probabilities, rather than average conditional probabilities. We conclude that from an optimality perspective, readers learn to select certain contiguous and non-contiguous letter combinations as information that provides the best cue to word identity.

    2016-02-01

    Spelling a word involves the retrieval of information about the word's letters and their order from long-term memory as well as the maintenance and processing of this information by working memory in preparation for serial production by the motor system. While it is known that brain lesions may selectively affect orthographic long-term memory and working memory processes, relatively little is known about the neurotopographic distribution of the substrates that support these cognitive processes, or the lesions that give rise to the distinct forms of dysgraphia that affect these cognitive processes. To examine these issues, this study uses a voxel-based mapping approach to analyse the lesion distribution of 27 individuals with dysgraphia subsequent to stroke, who were identified on the basis of their behavioural profiles alone, as suffering from deficits only affecting either orthographic long-term or working memory, as well as six other individuals with deficits affecting both sets of processes. The findings provide, for the first time, clear evidence of substrates that selectively support orthographic long-term and working memory processes, with orthographic long-term memory deficits centred in either the left posterior inferior frontal region or left ventral temporal cortex, and orthographic working memory deficits primarily arising from lesions of the left parietal cortex centred on the intraparietal sulcus. These findings also contribute to our understanding of the relationship between the neural instantiation of written language processes and spoken language, working memory and other cognitive skills.

    2016-05-01

    Full Text Available The present study attempts to employ orthographic knowledge enhancement as a tool in order to determine its efficiency in improving Iranian EFL learners’ reading comprehension. Orthographic knowledge can be defined as one’s familiarity with the general spelling rules of a language, or the ability to defer those letter combinations that are permissible form those that are not, which makes it an exceptional requirement for effective word identification and as a result successful reading comprehension skill. In doing so, 55 male and female students learning English at pre-intermediate level in a language institute in Astaneh, Guilan, Iran were randomly selected and were equally divided into an experimental and a control group. A researcher-made reading comprehension test followed by multiple-choice items as well as a word identification measure was given to both groups as a pre-test, and then the experimental group received the treatment in eighteen 30-minute sessions, in which the instructor taught skills to enhance students’ orthographic knowledge. Meanwhile, the control group did not receive any specific treatment. Finally the post-test, which was the same as the pre-test was administered. Their scores were calculated through computer softwares. The results indicated that raising orthographic knowledge results in significant improvement in both word identification and reading comprehension. The findings of this study can benefit EFL learners in improving their reading comprehension skill.Keywords: Orthographic knowledge, Word Identification, Reading comprehension, Iranian EFL Learners

  14. Orthographic versus semantic matching in visual search for words within lists.

    2012-03-01

    An eye-tracking experiment was performed to assess the influence of orthographic and semantic distractor words on visual search for words within lists. The target word (e.g., "raven") was either shown to participants before the search (literal search) or defined by its semantic category (e.g., "bird", categorical search). In both cases, the type of words included in the list affected visual search times and eye movement patterns. In the literal condition, the presence of orthographic distractors sharing initial and final letters with the target word strongly increased search times. Indeed, the orthographic distractors attracted participants' gaze and were fixated for longer times than other words in the list. The presence of semantic distractors related to the target word also increased search times, which suggests that significant automatic semantic processing of nontarget words took place. In the categorical condition, semantic distractors were expected to have a greater impact on the search task. As expected, the presence in the list of semantic associates of the target word led to target selection errors. However, semantic distractors did not significantly increase search times any more, whereas orthographic distractors still did. Hence, the visual characteristics of nontarget words can be strong predictors of the efficiency of visual search even when the exact target word is unknown. The respective impacts of orthographic and semantic distractors depended more on the characteristics of lists than on the nature of the search task.

    The purpose of this study was twofold: (a) to contrast the prominent theoretical explanations of the rapid automatized naming (RAN)-reading relationship across languages varying in orthographic consistency (Chinese, English, and Finnish) and (b) to examine whether the same accounts can explain the RAN-spelling relationship. In total, 304 Grade 4 children (102 Chinese-speaking Taiwanese children, 117 English-speaking Canadian children, and 85 Finnish-speaking children) were assessed on measures of RAN, speed of processing, phonological processing, orthographic processing, reading fluency, and spelling. The results of path analysis indicated that RAN had a strong direct effect on reading fluency that was of the same size across languages and that only in English was a small proportion of its predictive variance mediated by orthographic processing. In contrast, RAN did not exert a significant direct effect on spelling, and a substantial proportion of its predictive variance was mediated by phonological processing (in Chinese and Finnish) and orthographic processing (in English). Given that RAN predicted reading fluency equally well across languages and that phonological/orthographic processing had very little to do with this relationship, we argue that the reason why RAN is related to reading fluency should be sought in domain-general factors such as serial processing and articulation.

    The previous literature on working memory (WM) has indicated that verbal materials are dominantly retained in phonological representations, whereas other linguistic information (e.g., orthography, semantics) only contributes to verbal WM minimally, if not negligibly. Although accumulating evidence has suggested that multiple linguistic components jointly support verbal WM, the visual/orthographic contribution has rarely been addressed in alphabetic languages, possibly due to the difficulty of dissociating the effects of word forms from the effects of their pronunciations in relatively shallow orthography. In the present study, we examined whether the orthographic representations of Chinese characters support the retention of verbal materials in this language of deep orthography. In Experiments 1a and 2, we independently manipulated the phonological and orthographic similarity of horizontal and vertical characters, respectively, and found that participants' accuracy of probed serial recall was reduced by both similar pronunciations and shared phonetic radicals in the to-be-remembered stimuli. Moreover, Experiment 1b showed that only the effect of phonological, but not that of orthographic, similarity was affected by concurrent articulatory suppression. Taken together, the present results indicate the indispensable contribution of orthographic representations to verbal WM of Chinese characters, and suggest that the linguistic characteristics of a specific language not only determine long-term linguistic-processing mechanisms, but also delineate the organization of verbal WM for that language.

    Reading has been shown to rely on a dorsal brain circuit involving the temporoparietal cortex (TPC) for grapheme-to-phoneme conversion of novel words (Pugh et al., 2001), and a ventral stream involving left occipitotemporal cortex (OTC) (in particular in the so-called "visual word form area", VWFA) for visual identification of familiar words. In addition, portions of the inferior frontal cortex (IFC) have been posited to be an output of the dorsal reading pathway involved in phonology. While this dorsal versus ventral dichotomy for phonological and orthographic processing of words is widely accepted, it is not known if these brain areas are actually strictly sensitive to orthographic or phonological information. Using an fMRI rapid adaptation technique we probed the selectivity of the TPC, OTC, and IFC to orthographic and phonological features during single word reading. We found in two independent experiments using different task conditions in adult normal readers, that the TPC is exclusively sensitive to phonology and the VWFA in the OTC is exclusively sensitive to orthography. The dorsal IFC (BA 44), however, showed orthographic but not phonological selectivity. These results support the theory that reading involves a specific phonological-based temporoparietal region and a specific orthographic-based ventral occipitotemporal region. The dorsal IFC, however, was not sensitive to phonological processing, suggesting a more complex role for this region. PMID:27252037

    Two cohorts of children were followed to determine whether tests of phonological awareness (Syllable Tapping), orthographic processing (Visual Matching), and serial naming speed (RAN Objects), added to a preschool battery, would improve prediction of reading. The major predictors of first-grade reading and spelling were preschool letter naming and sentence memory for both cohorts, but the orthographic and serial naming tasks added a small amount of additional variance. Sentence memory accounted for the most variance in second-grade reading for both cohorts, and Visual Matching made contributions to reading and spelling for each cohort. Sentence memory, Visual Matching, and color naming together yielded an 87% to 90% hit rate in predicting which individual children would be good or poor readers. The orthographic and serial naming speed tasks are useful additions to a preschool predictive battery, but recommendations are that alternative preschool phonological tasks, not based on syllable recognition, should be used to predict reading.

    The NTA findings indicate that the relationship between orthographic and default-mode networks is characterized by greater within- vs. across-network connectivity. Furthermore, we show for the first time a pattern of increasing within/across network “coherence normalization” following spelling rehabilitation. Additional dysgraphic participants and other networks (language, sensory-motor, etc. will be analyzed to develop a better understanding of the RS orthographic network and its response to damage and recovery.

    In the quest to unveil the nature of the orthographic code, a useful strategy is to examine the transposed-letter effect (e.g., JUGDE is more confusable with its base word, JUDGE, than the replacement-letter nonword JUPTE). A leading explanation of this phenomenon, which is in line with models of visual attention, is that there is perceptual…

    Two experiments using the form-preparation paradigm were conducted to investigate the effect of orthographic form-cuing on the phonological preparation unit during spoken word production with native Mandarin speakers. In both experiments, participants were instructed to memorize nine prompt-response monosyllabic word pairs, after which an associative naming session was conducted in which the prompts were presented and participants were asked to say the corresponding response names as quickly and accurately as possible. In both experiments, the response words in the homogeneous lists shared the same onsets, or shared the same rimes; the response names had no common aspects of pronunciation in the heterogeneous lists. Chinese characters (Experiment 1) and Pinyin (phonetic transcription of the characters) (Experiment 2) were used to investigate the effect of the orthographic form. Significant onset facilitation and rime inhibition was shown for Pinyin syllables but not for characters. The contrasts of the onset and rime effect in the two orthographic forms suggest that a specific phonological unit is promoted in spoken word production in a certain orthographic form. Pinyin cued the participants to prepare the onset whereas Chinese characters did not. The rime interference effect may arise as a result of lexical competition in spoken word production.

    Orthographic regularity is important for processing Chinese characters. However, the issues how orthographic regularity influences the visual recognition of real Chinese characters and whether common processes related to the potential effect exist between successive (SUCC) and concurrent (CONC) conditions with asynchronous presentation of S1 and S2 are still unclear. In the current study, event-related potential (ERP) technique was adopted to investigate electrophysiological correlates of the orthographic regularity effect. Behaviorally, we found fewer errors and shorter response times for SUCC and CONC conditions compared to simultaneous (SIM) condition with synchronous presentation and disappearance of S1 and S2, which demonstrates similarities between SUCC and CONC and their differences from SIM. We found bilaterally smaller N170 responses for real Chinese characters preceded by false characters compared to real characters, demonstrating that orthographic regularity may inhibit the recognition of real Chinese characters. Additionally, the inhibition effect was present in SUCC and CONC rather than SIM, which shows that smaller N170 responses may have been due to asynchronous presentations of S1 and S2 and common inhibition processes in the SUCC and CONC conditions.

    2016-01-01

    The Stroop Color-Word Test involves a dynamic interplay between reading and executive functioning that elicits intuitions of word reading automaticity. One such intuition is that strong reading skills (i.e., more automatized word reading) play a disruptive role within the test, contributing to Stroop interference. However, evidence has accumulated that challenges this intuition. The present study examined associations among Stroop interference, reading skills (i.e., isolated word identification, grapheme-to-phoneme mapping, phonemic awareness, reading fluency) measured on standardized tests, and orthographic skills measured on experimental computerized tasks. Among university students (N = 152), correlational analyses showed greater Stroop interference to be associated with (a) relatively low scores on all standardized reading tests, and (b) longer response latencies on orthographic tasks. Hierarchical regression demonstrated that reading fluency and prelexical orthographic processing predicted unique and significant variance in Stroop interference beyond baseline rapid naming. Results suggest that strong reading skills, including orthographic processing, play a supportive role in resolving Stroop interference. PMID:26653862

  1. Influence of context-sensitive rules on the formation of orthographic representations in Spanish dyslexic children.

    Suárez-Coalla, Paz; Avdyli, Rrezarta; Cuetos, Fernando

    2014-01-01

    Spanish-speaking developmental dyslexics are mainly characterized by poor reading fluency. One reason for this lack of fluency could be a difficulty in creating and accessing lexical representations, because, as the self-teaching theory suggest, it is necessary to develop orthographic representations to use direct reading (Share, 1995). It is possible that this difficulty to acquire orthographic representations can be specifically related to words that contain context-sensitive graphemes, since it has been demonstrated that reading is affected by this kind of graphemes (Barca et al., 2007). In order to test this possibility we compared a group of dyslexic children with a group of normal readers (9-13 years), in a task of repeated reading. Pseudo-words (half short and half long) with simple and contextual dependent rules were used. The length effect reduction on the reading speed, after repeated exposure, was considered an indicator of orthographic representation development, as the length effect is strong when reading unknown words, but absent when reading familiar words. The results show that dyslexic children have difficulties in developing orthographic representations, not only with context-sensitive graphemes, but also with simple graphemes. In contrast to the control children, in the dyslexic group differences between reading times for short and long stimuli remained without significant changes after six presentations. Besides, this happened with sensitive context rules and also with simple grapheme-phoneme conversion rules. On the other hand, response and articulation times were greatly affected by length in dyslexic children, indicating the use of serial reading. Results suggest that the problems related to storing orthographic representations could be caused by a learning deficit, independently of whether the word contained context-sensitive rules or not.

    2015-04-01

    This article explores how letter position coding is attained during braille reading and its implications for models of word recognition. When text is presented visually, the reading process easily adjusts to the jumbling of some letters (jugde-judge), with a small cost in reading speed. Two explanations have been proposed: One relies on a general mechanism of perceptual uncertainty at the visual level, and the other focuses on the activation of an abstract level of representation (i.e., bigrams) that is shared by all orthographic codes. Thus, these explanations make differential predictions about reading in a tactile modality. In the present study, congenitally blind readers read sentences presented on a braille display that tracked the finger position. The sentences either were intact or involved letter transpositions. A parallel experiment was conducted in the visual modality. Results revealed a substantially greater reading cost for the sentences with transposed-letter words in braille readers. In contrast with the findings with sighted readers, in which there is a cost of transpositions in the external (initial and final) letters, the reading cost in braille readers occurs serially, with a large cost for initial letter transpositions. Thus, these data suggest that the letter-position-related effects in visual word recognition are due to the characteristics of the visual stream.

    2016-04-01

    A computer-generated hologram based on ray-wavefront conversion can reconstruct photorealistic three-dimensional (3D) images containing deep virtual objects and complicated physical phenomena; however, the required computational cost has been a problem that needs to be solved. In this Letter, we introduce the concept of an orthographic projection in the ray-wavefront conversion technique for reducing the computational cost without degrading the image quality. In the proposed method, plane waves with angular spectra of the object are obtained via orthographic ray sampling and Fourier transformation, and only the plane waves incident on the hologram plane are numerically propagated. We verified this accelerated computational method theoretically and experimentally, and demonstrated optical reconstruction of a deep 3D image in which the effects of occlusions, transmission, refraction, and reflection were faithfully reproduced.

    1997-01-01

    A methodology based upon recurrence quantification analysis is proposed for the study of orthographic structure of written texts. Five different orthographic data sets (20th century Italian poems, 20th century American poems, contemporary Swedish poems with their corresponding Italian translations, Italian speech samples, and American speech samples) were subjected to recurrence quantification analysis, a procedure which has been found to be diagnostically useful in the quantitative assessment of ordered series in fields such as physics, molecular dynamics, physiology, and general signal processing. Recurrence quantification was developed from recurrence plots as applied to the analysis of nonlinear, complex systems in the physical sciences, and is based on the computation of a distance matrix of the elements of an ordered series (in this case the letters consituting selected speech and poetic texts). From a strictly mathematical view, the results show the possibility of demonstrating invariance between diffe...

Such an orthographic word lexicon is posited by cognitive dual-route theories of reading and spelling. In the scanner, participants performed a spelling task in which they had to indicate if a visually presented letter is present in the written form of an auditorily presented word. The main experimental manipulatio...

    The aim of this study was to examine self-teaching in the context of English as a foreign language literacy acquisition. Three groups comprising 88 sixth-grade children participated. The first group consisted of Russian-Hebrew-speaking bilinguals who had acquired basic reading skills in Russian as their first language (L1) and literacy and who were literate in Hebrew as a second language. The second group consisted of Russian-Hebrew-speaking bilinguals who had not learned to read in their native Russian but had acquired Hebrew as their first literate language. The third group consisted of Hebrew-speaking monolingual children who were literate in Hebrew. This design facilitated examining the effect of biliteracy and bilingualism on basic English reading skills. We hypothesized that due to the proximity between the Russian and English orthographies as opposed to the Hebrew-English "distance," the Russian-Hebrew-speaking biliterate group who acquired basic reading and spelling skills in L1 Russian would have superior self-teaching in English as opposed to the two other groups. The standard two-session self-teaching paradigm was employed with naming (speed and accuracy) and orthographic choice as posttest measures of orthographic learning. Results showed that after 4 years of English instruction, all three groups showed evidence of self-teaching on naming speed and orthographic recognition. The Russian-Hebrew-speaking biliterate group, moreover, showed a partial advantage over the comparison groups for initial decoding of target pseudowords and clear-cut superiority for measures of later orthographic learning, thereby showing self-teaching while supporting the script dependence hypothesis.

  15. Orthographic processing in balanced bilingual children: Cross-language evidence from cognates and false friends.

    2016-01-01

    We investigated whether beginning bilingual readers activate orthographic as well as semantic representations in both of their languages while reading in one of them. Balanced bilingual third graders who were learning to read concurrently in German and English completed two lexical decision tasks, one in each language, including cognates, false friends, and matched control words. Results showed a processing advantage for cognates over controls in both languages, indicating that the facilitation effect is driven by the level of balanced language proficiency rather than by experience with print. Except for lower accuracy scores in German, false friends did not differ in their processing from controls, pointing to the presence of semantic-to-orthographic feedback already in the beginning of reading acquisition. Confirming assumptions by the bilingual interactive activation plus (BIA+) model as well as the revised hierarchical model (RHM), findings suggest that in their strategy to resolve orthographic ambiguity, balanced bilingual children are more comparable to bilingual adults than to child second-language (L2) learners.

    The objective of this research was to study the development of reading and spelling in French. The two main hypotheses were that (1) phonological mediation is the primary process in the acquisition of these skills and that (2) the use of phonological mediation may allow the construction of the orthographic lexicon. In January and June, first graders (n = 57) were required to read and spell items designed to assess the variables of regularity, graphemic complexity, frequency, lexicality and analogy. The findings of the January session partially corroborated the first hypothesis as a regularity effect, but no frequency effect and no word superiority, were found both in reading and spelling. The main contradictory finding was the presence, in early reading only, of a facilitative effect of analogy. The changes in the frequency and the lexicality effects between the two sessions in reading and in spelling indicated that the children were able to rapidly construct an orthographic lexicon. However, this procedure did not entirely replace phonological mediation since a regularity effect and regularization errors were observed and increased between sessions. The second hypothesis was supported as relationships were found to exist between early phonological skills and subsequent orthographic skills. Finally, we observed that French children were using graphemes (not only letters), in the early stage of reading, and, to a lesser extent, in the early stage of spelling. The findings are discussed in the context of developmental models of reading and spelling. PMID:9503649

    In this paper we discuss computational abstraction steps as a way to create class abstractions from concrete objects, and from examples. Computational abstraction steps are regarded as symmetric counterparts to computational concretisation steps, which are well-known in terms of function calls...... or capturing concrete values, objects, or actions. As the next step, some of these are lifted to a higher level by computational means. In the object-oriented paradigm the target of such steps is classes. We hypothesise that the proposed approach primarily will be beneficial to novice programmers or during...

    2005-01-01

    To most people the concept of abstract machines is connected to the name of Alan Turing and the development of the modern computer. The Turing machine is universal, axiomatic and symbolic (E.g. operating on symbols). Inspired by Foucault, Deleuze and Guattari extended the concept of abstract...... machines to singular, non-axiomatic and diagrammatic machines. That is: Machines which constitute becomings. This presentation gives a survey of the development of the concept of abstract machines in the philosophy of Deleuze and Guatari and the function of these abstract machines in the creation of works...... of art. From Difference and Repetition to Anti-Oedipus, the machines are conceived as binary machines based on the exclusive or inclusive use respectively of the three syntheses: conexa, disjuncta and conjuncta. The machines have a twofold embedment: In the desiring-production and in the social...

  10. Phonological and orthographic cues enhance the processing of inflectional morphology. ERP evidence from L1 and L2 French

    Directory of Open Access Journals (Sweden)

    Haydee eCarrasco-Ortiz

    2014-08-01

    Full Text Available We report the results of two ERP experiments in which Spanish learners of French and native French controls show graded sensitivity to verbal inflectional errors as a function of the presence of orthographic and/or phonological cues when reading silently in French. In both experiments, verbal agreement was manipulated in sentential context such that subject verb agreement was either correct, ill-formed and orally-realized, involving both orthographic and phonological cues, or ill-formed and silent which involved only orthographic cues. The results of both experiments revealed more robust ERP responses to orally-realized than to silent inflectional errors. This was true for L2 learners as well as native controls, although the effect in the learner group was reduced in comparison to the native group. In addition, the combined influence of phonological and orthographic cues led to the largest differences between morphosyntactic conditions. Overall, the results suggest that the presence of phonological cues may enhance L2 readers’ sensitivity to morphology but that such may appear in L2 processing only when sufficient proficiency is attained. Moreover, both orthographic and phonological cues are used when available.

  11. The effect of orthographic uniqueness and deviation points on lexical decisions: evidence from unilateral and bilateral-redundant presentations.

    2003-02-01

    Words with an early or late orthographic uniqueness point and nonwords with an early or late orthographic deviation point were presented to the left, right, or both visual fields simultaneously. In Experiment 1, 20 participants made lexical decision judgements to horizontal stimulus presentations. In Experiment 2, a further 20 participants completed the task using vertical presentations to control for attentional biases. Consistent with previous research, words with earlier orthographic uniqueness points prompted faster responses across visual fields, regardless of stimulus orientation. Although research has suggested that the left hemisphere's superiority for language processing stems from a comparatively parallel processing strategy, with the right hemisphere reliant upon a serial mechanism, left and right visual field presentations were not differentially affected by orthographic uniqueness point. This suggests that differential sequential effects previously reported result during processes other than retrieval from the lexicon. The overall right visual field advantage observed using horizontal presentations disappeared when stimuli were presented vertically. Contrary to expectations, there was a facilitatory effect of late orthographic deviation point for horizontal nonword presentations. Overall, the results were interpreted as being consistent with predictions of a cohort model of word recognition, and they highlighted the effect of stimulus orientation on left and right hemisphere word recognition.

  12. Metacognition and abstract reasoning.

    Markovits, Henry; Thompson, Valerie A; Brisson, Janie

    2015-05-01

    The nature of people's meta-representations of deductive reasoning is critical to understanding how people control their own reasoning processes. We conducted two studies to examine whether people have a metacognitive representation of abstract validity and whether familiarity alone acts as a separate metacognitive cue. In Study 1, participants were asked to make a series of (1) abstract conditional inferences, (2) concrete conditional inferences with premises having many potential alternative antecedents and thus specifically conducive to the production of responses consistent with conditional logic, or (3) concrete problems with premises having relatively few potential alternative antecedents. Participants gave confidence ratings after each inference. Results show that confidence ratings were positively correlated with logical performance on abstract problems and concrete problems with many potential alternatives, but not with concrete problems with content less conducive to normative responses. Confidence ratings were higher with few alternatives than for abstract content. Study 2 used a generation of contrary-to-fact alternatives task to improve levels of abstract logical performance. The resulting increase in logical performance was mirrored by increases in mean confidence ratings. Results provide evidence for a metacognitive representation based on logical validity, and show that familiarity acts as a separate metacognitive cue. PMID:25416026

  14. An introduction to abstract algebra

    CERN Document Server

    Robinson, Derek JS

    2003-01-01

    This is a high level introduction to abstract algebra which is aimed at readers whose interests lie in mathematics and in the information and physical sciences. In addition to introducing the main concepts of modern algebra, the book contains numerous applications, which are intended to illustrate the concepts and to convince the reader of the utility and relevance of algebra today. In particular applications to Polya coloring theory, latin squares, Steiner systems and error correcting codes are described. Another feature of the book is that group theory and ring theory are carried further than is often done at this level. There is ample material here for a two semester course in abstract algebra. The importance of proof is stressed and rigorous proofs of almost all results are given. But care has been taken to lead the reader through the proofs by gentle stages. There are nearly 400 problems, of varying degrees of difficulty, to test the reader''s skill and progress. The book should be suitable for students ...

    The primary purpose of this model report is to develop abstractions for the response of engineered barrier system (EBS) components to seismic hazards at a geologic repository at Yucca Mountain, Nevada, and to define the methodology for using these abstractions in a seismic scenario class for the Total System Performance Assessment - License Application (TSPA-LA). A secondary purpose of this model report is to provide information for criticality studies related to seismic hazards. The seismic hazards addressed herein are vibratory ground motion, fault displacement, and rockfall due to ground motion. The EBS components are the drip shield, the waste package, and the fuel cladding. The requirements for development of the abstractions and the associated algorithms for the seismic scenario class are defined in ''Technical Work Plan For: Regulatory Integration Modeling of Drift Degradation, Waste Package and Drip Shield Vibratory Motion and Seismic Consequences'' (BSC 2004 [DIRS 171520]). The development of these abstractions will provide a more complete representation of flow into and transport from the EBS under disruptive events. The results from this development will also address portions of integrated subissue ENG2, Mechanical Disruption of Engineered Barriers, including the acceptance criteria for this subissue defined in Section 2.2.1.3.2.3 of the ''Yucca Mountain Review Plan, Final Report'' (NRC 2003 [DIRS 163274]).

  15. EBS Radionuclide Transport Abstraction

    Energy Technology Data Exchange (ETDEWEB)

    R. Schreiner

    2001-06-27

    The purpose of this work is to develop the Engineered Barrier System (EBS) radionuclide transport abstraction model, as directed by a written development plan (CRWMS M&O 1999a). This abstraction is the conceptual model that will be used to determine the rate of release of radionuclides from the EBS to the unsaturated zone (UZ) in the total system performance assessment-license application (TSPA-LA). In particular, this model will be used to quantify the time-dependent radionuclide releases from a failed waste package (WP) and their subsequent transport through the EBS to the emplacement drift wall/UZ interface. The development of this conceptual model will allow Performance Assessment Operations (PAO) and its Engineered Barrier Performance Department to provide a more detailed and complete EBS flow and transport abstraction. The results from this conceptual model will allow PA0 to address portions of the key technical issues (KTIs) presented in three NRC Issue Resolution Status Reports (IRSRs): (1) the Evolution of the Near-Field Environment (ENFE), Revision 2 (NRC 1999a), (2) the Container Life and Source Term (CLST), Revision 2 (NRC 1999b), and (3) the Thermal Effects on Flow (TEF), Revision 1 (NRC 1998). The conceptual model for flow and transport in the EBS will be referred to as the ''EBS RT Abstraction'' in this analysis/modeling report (AMR). The scope of this abstraction and report is limited to flow and transport processes. More specifically, this AMR does not discuss elements of the TSPA-SR and TSPA-LA that relate to the EBS but are discussed in other AMRs. These elements include corrosion processes, radionuclide solubility limits, waste form dissolution rates and concentrations of colloidal particles that are generally represented as boundary conditions or input parameters for the EBS RT Abstraction. In effect, this AMR provides the algorithms for transporting radionuclides using the flow geometry and radionuclide concentrations

    This study examined whether and how the morphological structure of written words affects reading in word-based neglect dyslexia (neglexia), and what can be learned about morphological decomposition in reading from the effect of morphology on neglexia. The oral reading of 7 Hebrew-speaking participants with acquired neglexia at the word level-6 with left neglexia and 1 with right neglexia-was evaluated. The main finding was that the morphological role of the letters on the neglected side of the word affected neglect errors: When an affix appeared on the neglected side, it was neglected significantly more often than when the neglected side was part of the root; root letters on the neglected side were never omitted, whereas affixes were. Perceptual effects of length and final letter form were found for words with an affix on the neglected side, but not for words in which a root letter appeared in the neglected side. Semantic and lexical factors did not affect the participants' reading and error pattern, and neglect errors did not preserve the morpho-lexical characteristics of the target words. These findings indicate that an early morphological decomposition of words to their root and affixes occurs before access to the lexicon and to semantics, at the orthographic-visual analysis stage, and that the effects did not result from lexical feedback. The same effects of morphological structure on reading were manifested by the participants with left- and right-sided neglexia. Since neglexia is a deficit at the orthographic-visual analysis level, the effect of morphology on reading patterns in neglexia further supports that morphological decomposition occurs in the orthographic-visual analysis stage, prelexically, and that the search for the three letters of the root in Hebrew is a trigger for attention shift in neglexia.

    2013-01-01

    This volume unites spelling and word recognition -- two areas that have largely remained theoretically and empirically distinct. Despite considerable advances in the investigation of processes underlying word perception and the acknowledgement of the seminal importance of lexical access in the reading and writing processes, to date the development and functioning of orthographic knowledge across both encoding and decoding contexts has rarely been explored. The book begins to fill this void by offering a coherent and unified articulation of the perceptual, linguistic, and cognitive fea

In auditory lexical decision experiments, words that can only be spelled one way are recognized faster than words with multiple potential spellings. Previous.......g., lobe) faster than words with consistent rhymes where the vowel has a less typical spelling (e.g., loaf). The present study extends previous literature by showing that auditory word recognition is affected by orthographic regularities at different grain sizes, just like written word recognition...

    The Position of Capitalist Study in Marx's Social Formation Theory Yang Xue-gong Xi Da-min The orientation and achievements of Marx's study of Capitalism or bourgeois society is the foundation of his social formation theory. On the base of his scientific study of capitalism, Marx evolves his concept of eco- nomic social formation, the scientific methodology of researching other social formations or social forms, the clues of the development of social formations, the abstraction of the general laws as well as his reflection on this abstraction. A full evaluation and acknowledgement of the position of capitalist study in Marx's social formation theory is crucial for revising Marx's social formation theory in the new era and for solving some controversial issues in the research of social formation theory.

  8. Coupling CFD code with system code and neutron kinetic code

    International Nuclear Information System (INIS)

    Highlights: • Coupling interface between CFD code Fluent and system code Athlet was created. • Athlet code is internally coupled with neutron kinetic code Dyn3D. • Explicit coupling of overlapped computational domains was used. • A coupled system of Athlet/Dyn3D+Fluent codes was successfully tested on a real case. - Abstract: The aim of this work was to develop the coupling interface between CFD code Fluent and system code Athlet internally coupled with neutron kinetic code Dyn3D. The coupling interface is intended for simulation of complex transients such as Main Steam Line Break scenarios, which cannot be modeled separately first by system and neutron kinetic code and then by CFD code, because of the feedback between the codes. In the first part of this article, the coupling method is described. Explicit coupling of overlapped computational domains is used in this work. The second part of the article presents a demonstration simulation performed by the coupled system of Athlet/Dyn3D and Fluent. The “Opening a Steam Dump to the Atmosphere” test carried out at the Temelin NPP (VVER-1000) was simulated by the coupled system. In this simulation, the primary and secondary circuits were modeled by Athlet, mixing in downcomer and lower plenum was simulated by Fluent and heat generation in the core was calculated by Dyn3D. The results of the simulation with Athlet/Dyn3D+Fluent were compared with the experimental data and the results from a calculation performed with Athlet/Dyn3D without Fluent

  9. EBS Radionuclide Transport Abstraction

    International Nuclear Information System (INIS)

    The purpose of this report is to develop and analyze the engineered barrier system (EBS) radionuclide transport abstraction model, consistent with Level I and Level II model validation, as identified in Technical Work Plan for: Near-Field Environment and Transport: Engineered Barrier System: Radionuclide Transport Abstraction Model Report Integration (BSC 2005 [DIRS 173617]). The EBS radionuclide transport abstraction (or EBS RT Abstraction) is the conceptual model used in the total system performance assessment (TSPA) to determine the rate of radionuclide releases from the EBS to the unsaturated zone (UZ). The EBS RT Abstraction conceptual model consists of two main components: a flow model and a transport model. Both models are developed mathematically from first principles in order to show explicitly what assumptions, simplifications, and approximations are incorporated into the models used in the TSPA. The flow model defines the pathways for water flow in the EBS and specifies how the flow rate is computed in each pathway. Input to this model includes the seepage flux into a drift. The seepage flux is potentially split by the drip shield, with some (or all) of the flux being diverted by the drip shield and some passing through breaches in the drip shield that might result from corrosion or seismic damage. The flux through drip shield breaches is potentially split by the waste package, with some (or all) of the flux being diverted by the waste package and some passing through waste package breaches that might result from corrosion or seismic damage. Neither the drip shield nor the waste package survives an igneous intrusion, so the flux splitting submodel is not used in the igneous scenario class. The flow model is validated in an independent model validation technical review. The drip shield and waste package flux splitting algorithms are developed and validated using experimental data. The transport model considers advective transport and diffusive transport

    2012-01-01

    Full Text Available It is habitual for graduating students of the Obafemi Awolowo University, Ile-Ife, Nigeria, to roll out the drums the very day they finish writing their final examination. Characteristic of such a ritualistic exercise, among other things, are the brand names the students coin for themselves from their original names. This study focuses on the creative rewriting of the names on such an occasion and examines the linguistic habits exhibited therein. It analyses the phonological/graphematic features that mark the rewritng of the names and discusses the sociolinguistic implications for the phenomena of social identity construction and language contact situation. Data for the study was sourced mainly through participant-observation technique with a supplemment of an oral interview conducted for some of the subjects between year 2007 and 2009. The data was selected through a purposive random sampling technique which yielded fifty names that were considered representative of the respelling conventions. The paper employs mainly Hempenstall's (2003 Phonological Sensitivity Skills to analyse the linguistic practices in the reconfigured names and then applies Tajfel's and Turner's (1979 Social Identity Theory to explain how it is that people develop a sense of membership and belonging in particular groups. The article reveals that the deviant orthographic conventions are a major fallout of youth culture with great influence from computer-mediated communication. It also shows that their linguistic experimentation foray in the discourse greatly undermines the orthographic system of the indigenous language (Yoruba and the cultural values embedded in the original names.

Circular...... unknowns from what is done to them, which we lambda-abstract with functions. The circular unknowns then become dead variables, which we eliminate.

  20. Orthographic Reading Deficits in Dyslexic Japanese Children: Examining the Transposed-Letter Effect in the Color-Word Stroop Paradigm

    Ogawa, Shino; Shibasaki, Masahiro; Isomura, Tomoko; Masataka, Nobuo

    2016-01-01

    In orthographic reading, the transposed-letter effect (TLE) is the perception of a transposed-letter position word such as “cholocate” as the correct word “chocolate.” Although previous studies on dyslexic children using alphabetic languages have reported such orthographic reading deficits, the extent of orthographic reading impairment in dyslexic Japanese children has remained unknown. This study examined the TLE in dyslexic Japanese children using the color-word Stroop paradigm comprising congruent and incongruent Japanese hiragana words with correct and transposed-letter positions. We found that typically developed children exhibited Stroop effects in Japanese hiragana words with both correct and transposed-letter positions, thus indicating the presence of TLE. In contrast, dyslexic children indicated Stroop effects in correct letter positions in Japanese words but not in transposed, which indicated an absence of the TLE. These results suggest that dyslexic Japanese children, similar to dyslexic children using alphabetic languages, may also have a problem with orthographic reading. PMID:27303331

  1. The effects of orthographic transparency and familiarity on reading Hebrew words in adults with and without dyslexia.

    2015-07-01

    The current study examined the effects of transparency and familiarity on word recognition in adult Hebrew dyslexic readers with a phonological processing deficit as compared to typical readers. We measured oral reading response time and accuracy of single nouns in several conditions: diacritics that provide transparent but less familiar information and vowel letters that increase orthographic transparency without compromise familiarity. In line with former studies with adult dyslexics, Hebrew-speaking adults with dyslexia were significantly slower than controls. However, both dyslexic and typical readers read unpointed words faster when vowel letters were present, indicating that they may benefit from increase in orthographic transparency, when the graphemic representations are familiar. Only dyslexics read pointed words slower than unpointed words and were more sensitive to word frequency. In unpointed words, only typical readers benefitted from the reduced competition of orthographic neighbors of longer words. Results indicate that both orthographic transparency and familiarity play an important role in word recognition. Dyslexics are impaired in decoding of smaller units and are more sensitive to reduction in the familiarity of words.

    Determination of the Estrogen Alkylphenols and Bisphenol A in Marine Sediments by Gas Chromatography-Mass Spectrometry Deng Xu-xiu et al. (1) Abstract Octylphenol, nonylphenol and bisphenol A are recognized environmental endocrine disruptors. A quantitative method was established for the simultaneous determination of octylphenol, nonylphenol and bisphenol A in marine sediments by gas chromatography-mass spectrometry. The test sample was extracted by methanol with ultrasonic technique, purified with copper powder and carbon solid phase extraction column, and derived with heptafluorobutyric anhydride. Then the analytes were separated on HP-5ms column and determined by gas chromatography-mass. The recovery of the method was between 84.3% and 94.5%, and the LOQ of 4-N- octylphenol, nonylphenol and bisphenol A was 0.25 g/kg, 0.15 g/kg and 0.15 g/kg.

    [Ancient Mediterranean Civilizations] Title: On Poseidon's Image in Homeric Epics Author: Zhu Yizhang, Lecturer, School of History and Culture, Shandong University, Jinan, Shandong, 250100, China. Abstract: Poseidon was an important role in religion, myth and literature of ancient Greece. His religious functions, and status in mythical image in literature were mainly established by Homeric Epics. Poseidon doesn't only appear frequently in the Homeric Epics but also influences the development of the plots directly; therefore, he could be seen as one of the most important gods in the Epics. But Homeric Epics do not introduce his basic image clearly. In Homeric Epics, Poseidon carries the deity and humanity aspect of the figure, and the latter was emphasized, which implied his archetype was a mortal wanax.

    On the Social Solidarity of Organization An Empirical Analysis Li Hanlin Abstract: Based on the 2002 survey data, this paper tries to measure solidarity in organization. The operationalization for this measurement goes from two points of view. One is from the degree of cohesion and another one is from the degree of vulnerability. To observe and measure the degree of cohesion three subscales like social support, vertical integration and organizational identity have been used. To observe and measure the degree of vulnerability other three subscales like dissatisfaction, relative deprivation and anomie have been used. The paper tries to explore finally under which condition the organization behavior and behavior orientation could go to the similarity or make some difference. Key words: Organization Cohesion Vulnerability Organization Behavior

    (Abstract only) The AAVSO is in the process of expanding its education, outreach and speakers bureau program. powerpoint presentations prepared for specific target audiences such as AAVSO members, educators, students, the general public, and Science Olympiad teams, coaches, event supervisors, and state directors will be available online for members to use. The presentations range from specific and general content relating to stellar evolution and variable stars to specific activities for a workshop environment. A presentation—even with a general topic—that works for high school students will not work for educators, Science Olympiad teams, or the general public. Each audience is unique and requires a different approach. The current environment necessitates presentations that are captivating for a younger generation that is embedded in a highly visual and sound-bite world of social media, twitter and U-Tube, and mobile devices. For educators, presentations and workshops for themselves and their students must support the Next Generation Science Standards (NGSS), the Common Core Content Standards, and the Science Technology, Engineering and Mathematics (STEM) initiative. Current best practices for developing relevant and engaging powerpoint presentations to deliver information to a variety of targeted audiences will be presented along with several examples.

    Full Text Available In two experiments the judgement of twenty one abstract paintings was investigated. In Experiment 1, subjects were asked to make similarity judgements of 210 pairs of paintings on a 7 step bipolar scale (similar-dissimilar. The Multi-dimensional scaling (MDS method was used for data analysis. The distribution of paintings within MDS 2-D space suggested two grouping criteria: colorfullness (e.g. from Klee to Kline and geometrization (e.g. from Vasarely to Kandinsky. In Experiment 2, subjects were asked to judge the same paintings on three factors of the instrument SDF 9 (Marković et al., 2002b: Evaluation, Arousal and Regularity. The purpose of this experiment was to specify the subjective criteria on which the (dissimilarity judgements were based. In the regression analysis the three factors of SDF 9 were defined as predictors, whereas the x and y coordinates of MDS 2-D space were defined as dependent variables. The results have shown that the dimension x was reducible to the Evaluation factor, and dimension y is reducible to the Regularity factor.

  18. The influence of orthographic consistency on reading development: word recognition in English and German children.

    Wimmer, H; Goswami, U

    1994-01-01

    Groups of 7, 8, and 9-year-old children who were learning to read in English and German were given three different continuous reading tasks: a numeral reading task, a number word reading task, and a nonsense word reading task. The nonsense words could be read by analogy to the number words. Whereas reading time and error rates in numeral and number word reading were very similar across the two orthographies, the German children showed a big advantage in reading the nonsense words. This pattern of results is interpreted as evidence for the initial adoption of different strategies for word recognition in the two orthographies. German children appear to rely on assembling pronunciations via grapheme-phoneme conversion, and English children appear to rely more on some kind of direct recognition strategy. A model of reading development that takes account of orthographic consistency is proposed. PMID:8149718

    2006-11-01

    Neuropsychological and neurophysiological evidence point to a role for the left fusiform gyrus in visual word recognition, but the specific nature of this role remains a topic of debate. The aim of this study was to measure the sensitivity of this region to sublexical orthographic structure. We measured blood oxygenation (BOLD) changes in the brain with functional magnetic resonance imaging while fluent readers of English viewed meaningless letter strings. The stimuli varied systematically in their approximation to English orthography, as measured by the probability of occurrence of letters and sequential letter pairs (bigrams) comprising the string. A whole-brain analysis showed a single region in the lateral left fusiform gyrus where BOLD signal increased with letter sequence probability; no other brain region showed this response pattern. The results suggest tuning of this cortical area to letter probabilities as a result of perceptual experience and provide a possible neural correlate for the 'word superiority effect' observed in letter perception research.

    We propose a fast calculation method to synthesize a computer-generated hologram (CGH) of realistic deep three-dimensional (3D) scene. In our previous study, we have proposed a calculation method of CGH for reproducing such scene called ray-sampling-plane (RSP) method, in which light-ray information of a scene is converted to wavefront, and the wavefront is numerically propagated based on diffraction theory. In this paper, we introduce orthographic projection to the RSP method for accelerating calculation time. By numerical experiments, we verified the accelerated calculation with the ratio of 28-times compared to the conventional RSP method. The calculated CGH was fabricated by the printing system using laser lithography and demonstrated deep 3D image reconstruction in 52mm×52mm with realistic appearance effect such as gloss and translucent effect.

However, very little is known about how teache...

  2. Abstraction of Drift Seepage

    Energy Technology Data Exchange (ETDEWEB)

    J.T. Birkholzer

    2004-11-01

    This model report documents the abstraction of drift seepage, conducted to provide seepage-relevant parameters and their probability distributions for use in Total System Performance Assessment for License Application (TSPA-LA). Drift seepage refers to the flow of liquid water into waste emplacement drifts. Water that seeps into drifts may contact waste packages and potentially mobilize radionuclides, and may result in advective transport of radionuclides through breached waste packages [''Risk Information to Support Prioritization of Performance Assessment Models'' (BSC 2003 [DIRS 168796], Section 3.3.2)]. The unsaturated rock layers overlying and hosting the repository form a natural barrier that reduces the amount of water entering emplacement drifts by natural subsurface processes. For example, drift seepage is limited by the capillary barrier forming at the drift crown, which decreases or even eliminates water flow from the unsaturated fractured rock into the drift. During the first few hundred years after waste emplacement, when above-boiling rock temperatures will develop as a result of heat generated by the decay of the radioactive waste, vaporization of percolation water is an additional factor limiting seepage. Estimating the effectiveness of these natural barrier capabilities and predicting the amount of seepage into drifts is an important aspect of assessing the performance of the repository. The TSPA-LA therefore includes a seepage component that calculates the amount of seepage into drifts [''Total System Performance Assessment (TSPA) Model/Analysis for the License Application'' (BSC 2004 [DIRS 168504], Section 6.3.3.1)]. The TSPA-LA calculation is performed with a probabilistic approach that accounts for the spatial and temporal variability and inherent uncertainty of seepage-relevant properties and processes. Results are used for subsequent TSPA-LA components that may handle, for example, waste package

  5. From "cracking the orthographic code" to "playing with language": toward a usage-based foundation of the reading process.

    Science.gov (United States)

    Wallot, Sebastian

    2014-01-01

    The empirical study of reading dates back more than 125 years. But despite this long tradition, the scientific understanding of reading has made rather heterogeneous progress: many factors that influence the process of text reading have been uncovered, but theoretical explanations remain fragmented; no general theory pulls together the diverse findings. A handful of scholars have noted that properties thought to be at the core of the reading process do not actually generalize across different languages or from situations single-word reading to connected text reading. Such observations cast doubt on many of the traditional conceptions about reading. In this article, I suggest that the observed heterogeneity in the research is due to misguided conceptions about the reading process. Particularly problematic are the unrefined notions about meaning which undergird many reading theories: most psychological theories of reading implicitly assume a kind of elemental token semantics, where words serve as stable units of meaning in a text. This conception of meaning creates major conceptual problems. As an alternative, I argue that reading shoud be rather understood as a form of language use, which circumvents many of the conceptual problems and connects reading to a wider range of linguistic communication. Finally, drawing from Wittgenstein, the concept of "language games" is outlined as an approach to language use that can be operationalized scientifically to provide a new foundation for reading research.

    2016-05-01

    To examine phonological and orthographic effects on semantic processing, the present study utilized a semantic task with nonverbal stimuli. In Experiment 1, Hebrew speakers were asked to decide whether 2 pictorial targets are semantically related or not. In Experiment 2, Hebrew speakers and non-Hebrew speakers were asked to rate the semantic relatedness of the same targets on a 5-point scale. Experiment 3 was identical to the first experiment except that the 2 pictures were presented simultaneously rather than sequentially. In all experiments, we compared responses to semantically unrelated pairs in 2 conditions: In the ambiguous condition, each pair represented 2 distinct meanings of an ambiguous Hebrew word. In the unambiguous condition, the first picture was replaced with an unambiguous control. To disentangle phonological and orthographic effects, three types of Hebrew ambiguous words were used: homonyms, homophones, and homographs. Ambiguous pairs were more difficult to be judged as semantically unrelated in comparison to their unambiguous controls. Moreover, while non-Hebrew speakers did not distinguish between the 2 lexical conditions, Hebrew speakers rated ambiguous pairs as significantly more related than their unambiguous controls. Importantly, in general, the ambiguity effect was stronger for homonyms, where both lexical forms are shared, than for either homophones or homographs, which are only phonologically or orthographically related. Thus, consistent with interactive "triangle" models, the results suggest that (a) conceptual-semantic representations automatically activate both their corresponding phonological and orthographic lexical forms, and (b) these lexical forms, once activated, may in turn affect semantic-conceptual processes via feedback connections.

    The Twente Compiler Generator System (TCGS) is a parser-generator system which is typically used to generate a compiler that, given an input program, generates abstract stack code. A code generator for TCGS translates this stack code generated by a TCGS compiler to assembler code for a particular target machine. This thesis discusses two code generators for TCGS: GUMP and COGGEN. The simplest strategy to translate stack code into assembler code is to macro expand each stack code instruction t...

  11. Coding Partitions

    Directory of Open Access Journals (Sweden)

    Fabio Burderi

    2007-05-01

    Full Text Available Motivated by the study of decipherability conditions for codes weaker than Unique Decipherability (UD, we introduce the notion of coding partition. Such a notion generalizes that of UD code and, for codes that are not UD, allows to recover the ``unique decipherability" at the level of the classes of the partition. By tacking into account the natural order between the partitions, we define the characteristic partition of a code X as the finest coding partition of X. This leads to introduce the canonical decomposition of a code in at most one unambiguouscomponent and other (if any totally ambiguouscomponents. In the case the code is finite, we give an algorithm for computing its canonical partition. This, in particular, allows to decide whether a given partition of a finite code X is a coding partition. This last problem is then approached in the case the code is a rational set. We prove its decidability under the hypothesis that the partition contains a finite number of classes and each class is a rational set. Moreover we conjecture that the canonical partition satisfies such a hypothesis. Finally we consider also some relationships between coding partitions and varieties of codes.

    We compared reading acquisition in English and Italian children up to late primary school analyzing RTs and errors as a function of various psycholinguistic variables and changes due to experience. Our results show that reading becomes progressively more reliant on larger processing units with age, but that this is modulated by consistency of the language. In English, an inconsistent orthography, reliance on larger units occurs earlier on and it is demonstrated by faster RTs, a stronger effect of lexical variables and lack of length effect (by fifth grade). However, not all English children are able to master this mode of processing yielding larger inter-individual variability. In Italian, a consistent orthography, reliance on larger units occurs later and it is less pronounced. This is demonstrated by larger length effects which remain significant even in older children and by larger effects of a global factor (related to speed of orthographic decoding) explaining changes of performance across ages. Our results show the importance of considering not only overall performance, but inter-individual variability and variability between conditions when interpreting cross-linguistic differences.

    2006-01-01

    Several investigations have considered the spelling abilities of children with reading disability; however, the spelling patterns of children with a language learning disability (LLD) have been largely ignored. This study examined the spelling error patterns of three groups of children who met strict inclusion criteria-those with a known LLD (n = 8), chronological-age-matched peers (CA; n = 8), and a younger spelling-age-matched group (SA; n = 8). An experimental spelling measure was specially designed and administered to elucidate the underlying linguistic features (clusters, digraphs, etc.) and linguistic classifications (phonological, orthographical, morphological) of misspellings. Based on inferential statistical analyses, a general pattern was that the LLD group and the SA group always differed from the CA group, whereas the LLD group performed similarly to the SA group. This finding lends credence to the hypothesis that children with an LLD, like children with reading disability, are delayed in spelling development rather than following a deviant developmental process. However, a qualitative analysis indicated two specific patterns. First, the LLD group had more trouble than did the SA group in representing the basic phonological structure of words, when complexity was increased by word length or linguistic structure. Second, in contrast to the SA group, the LLD group had greater omissions of inflected and derived morphological markers. These findings point to the critical role of morphology as the mediator between and form and meaning.

  20. Orthographic units in the absence of visual processing: Evidence from sublexical structure in braille.

    Science.gov (United States)

    Fischer-Baum, Simon; Englebretson, Robert

    2016-08-01

    Reading relies on the recognition of units larger than single letters and smaller than whole words. Previous research has linked sublexical structures in reading to properties of the visual system, specifically on the parallel processing of letters that the visual system enables. But whether the visual system is essential for this to happen, or whether the recognition of sublexical structures may emerge by other means, is an open question. To address this question, we investigate braille, a writing system that relies exclusively on the tactile rather than the visual modality. We provide experimental evidence demonstrating that adult readers of (English) braille are sensitive to sublexical units. Contrary to prior assumptions in the braille research literature, we find strong evidence that braille readers do indeed access sublexical structure, namely the processing of multi-cell contractions as single orthographic units and the recognition of morphemes within morphologically-complex words. Therefore, we conclude that the recognition of sublexical structure is not exclusively tied to the visual system. However, our findings also suggest that there are aspects of morphological processing on which braille and print readers differ, and that these differences may, crucially, be related to reading using the tactile rather than the visual sensory modality.

    In literates, reading is a fundamental channel for acquiring new vocabulary both in the mother tongue and in foreign languages. By using an artificial language learning task, we examined the acquisition of novel written words and their embedded regularities (an orthographic surface feature and a syllabic feature) in three groups of university students with different exposures (Group 1 saw 2 words once, Group 2 saw 20 words once, Group 3 saw 20 words three times). Recognition memory results for Groups 2 and 3 indicated that adults can learn novel written words even with just a single exposure, albeit repeated exposure improved target detection. A generalization task revealed that even the minimal exposure in Group 1 was enough for acquisition of the two embedded regularities. More exemplars and repeated exposure provided more robust effects for the syllable regularity. Finally, post-test interview showed that repeated exposure was needed to become aware of the regularities. The present results show that adults learn novel written words and their inherent regularities in a fast and effective fashion.

    (1) The Narrative Structure and Mode of Realization of Marx's Theory of Human Emancipation Liu Tongfang Understanding the inherent logic of the ideas in the classic Marxist texts and revealing the narrative structure and mode of realization of Marx's theory of human emancipation is an important intellectual approach to the extension of Marxist theoretical research. As a scientific theory of the history of society, the narrative structure of human emancipation involves three aspects: historical materialism, multi-dimensional forms of emancipation, and communist movements. It offers a comprehensive analysis of the basic way of perceiving human society, the fundamental path to human emancipation and the ultimate aim of the evolution of social forms. It reflects the thorough-going revolutionary nature of Marx's theory of human emancipation and its close relationship with the real life of society. It would thus be academically significant to reflect on Western Marxism, Soviet-type socialism and the socialist road with Chinese characteristics from the viewpoint of the narrative structure of Marx's theory of human emancipation, so as to extend the Marxist theory of human emancipation and explore its specific mode of realization

    International Norms, Group Identity and Domestic Institutional Re- form: The Case of China's Entrance to FATF Lie Xinghua Abstract: International norms are the collection of binding rules governing the international community. International norms with high levels of legitimacy result in norm groups. Such norm groups directly affect the space for and effectiveness of behavior. In order to enter a norm group and obtain membership status within the group, states must engage in domestic institu- tional reforms in order to meet standards of admission. In order to enter FATF, China studied the principles of the 40+ 9 Recommendations, and ad- vanced comprehensive domestic reforms to counter money laundering.

    Plato on Political Rhetoric Generally, Plato was regarded as being hostile to rhetoric. However, I will show that in Plato's some important political dialogues he still verifies the significance of rhetoric or persuasion. Then, I list the attacks of Plato on his contemporary rhetoric, which is called in the essay as "politician rhetoric". On the other hand, Plato also articu- lates the characteristics of true rlhetoric, which I name as "dialectical rhetoric. " In order to elaborate "dialectical rhetoric", I take Pericles as an example to show how the dialectic rhetoric could work in the real political world. Finally, I point out that dialectical rhetoric still can give some reflection for today's political rhetoric. It contains the ideal of the good, caring the soul of the audience, speaking the truth, insisting the right thing with reason, etc.

    The Introduction of Western Learning to the East and the Sinicization of Marxist Philosophy The introduction of western learning to the east objectively promoted the dissemination of Marxist philosophy in China, forming an important historical prerequisite for the sinicization of Marxist philosophy. Moreover, it also triggered a great transformation in the historical development of Chinese philosophy and facilitated its transition from ancient to early modern traditions, thereby establishing through sinicization a link between Marxist philosophy, which originated in the western philosophical tradition, and the Chinese tradition of philosophy, and rendering Marxist philosophy Chinese. This offered the possibility that sinicized Marxist philosophy would play a positive guiding role in the development of modern Chinese philosophy. Therefore, we may say that without the introduction of western learning to the east, there would be no sinicization of Marxist Ichilosophy; and without in-depth research on the relationship between the introduction of western learning to the east and the sinicization of Marxist philosophy, there would be no real understanding of the sinicization of Marxist philosophy. However, the close links between the sinicization of Marxist philosophy and the introduction of western learning do not indicate that the sinicization of Marxist philosophy is part of the history of the introduction of western learning to the east. The sinicization of Marxist philosophy does not itself belong to the category of the spread of western learning to the east. This is because Marxist philosophy is essentially different from all other commonly known western sciences; its sinicization differs from the eastward spread of western learning in terms of its goals, social nature, results and effects on society.

    The modem transition of philosophy is the transition of world metaphysics to conscious metaphysics therefore the aprioristic philosophy exploring the consciousness has taken place which experienced the three progressing periods from Descartes to Kant to Edmund Husserl: Descartes tried to prove that consciousness was the unique and stable starting point of understanding all problems, and Kant tried to prove that consciousness had the ability to build up effec- tive knowledge as well as had the ability to guide the right behavior, while Edmund Husserl tried to prove that conscious- ness had the overall object, which relatively equal to had its own word. Through these three great and difficult periods of efforts, aprioristic conscious philosophy has completed the proving of the arguments of I think and thinking, nevertheless, the arguments did not reach to the level of laying the foundation, therefore they did not interpret the world correctly.

    The Practice and Implications of Judicial Innovation: A Study of Administrative Litigation from City T Drawing on data from a mid-sized city, this article finds that the courts, caught between the unruly adminis- trative agencies and legal rhetoric, seek support from the Party to enhance their authority. They then devise tac- tics such as putting the chief official of agencies on the stand, issuing judicial suggestions, and innovatively ap- plying the laws. Contrary to the conventional wisdom that the courts are only a passive actor in local politics, the development indicates that the role of the courts is by no means negligible in translating the national laws into lo- cal practice. Social stability, industrial structure, the power and resource of administrative agencies, and profes- sionalism of court staff are important factors affecting the development of the rule of law.

    Scientific Culture and Cultural Science (p.1) Today science advances at an astonishingly high speed, and driven by the ideological and industrial revolutions, it even becomes a dominant culture in the society and is respected as the supreme authority. However, the scientific culture, which plays the leading role in the industrial civilization, turns out to be more and more alienated from culture and humanity, resulting in the so-called cultural confusions and loss of humanity. This article, investigating the phenomenon deeply, argues that science has no privileged position over the other cultural traditions, and suggests that science identify itself as a member equal with the other cultural patterns in the society in order to restore its cultural connotations. It is believed that by establishing the cultural science, we can bring culture and humanity back to science.

    Full Text Available This paper aims to describe and to analyze the integration observed in the Sintonia project with respect to the comparison of project management processes to the model of the Stage-Gate ®. The literature addresses these issues conceptually, but lack an alignment between them that is evident in practice. As a method was used single case study. The report is as if the Sintonia project, developed by PRODESP - Data Processing Company of São Paulo. The results show the integration of project management processes with the Stage-Gate model developed during the project life cycle. The formalization of the project was defined in stages in which allowed the exploitation of economies of repetition and recombination to the development of new projects. This study contributes to the technical vision in dealing with the integration of project management processes. It was concluded that this system represents an attractive way, in terms of creating economic value and technological innovation for the organization.

    When discussing the maturation of Chinese sociology, one has to reconsider the relationsbetween Western sociology and Chinese sociology and distinguish the flows from their sources ifone wants to find a way forward for Chinese sociology. Chinese sociology should view theresources of homegrown sociological tradition as a "source, " which is represented by "qunxue"(literally the study of groups).

    Full Text Available The present study has the objective of verifying if simultaneous investments in several international stock markets are more attractive than in only one national stock market, in other words, if the first ones present a superior risk-return relationship. It can be admitted that if there is a total integration among the analyzed countries, there is little advantage in the international diversification, but if the countries are less integrated, the diversification would bring advantages in risk-return terms. The empirical work is based on Markowitz portfolio theory, CAPM and in the portfolio performance measures of Sharpe, Treynor, and Jensen. The analysis was made for the period of February 1993 to January 2003, based in the most liquid stocks negotiated in the stock market of the main countries of Latin America. The results showed that portfolio diversification in international markets is a better approach.

In 1954, China proposed the five principles of "peaceful coexistence". Atthe Bandung Conference in 1955, China, India and Myanmar jointly advocated thefive principles as a means of good governance in Asia and the whole world. Earlyin the 21st century, China proposed a new concept of "win-win cooperation" as animportant principle for international relations in the new global era.

    Changing the Means of Structural Adjustment for Transformation of Development Pattern SONG Ze Abstract: History of China's reform and opening up has proven that government-led industrial structural adjustment is unsuccessful. Facing the new situation and economic development tasks, new ideas of industrial restructuring should be clearly put forward that the government will create conditions to adjust the structure by the market. During the Twelve-Five Years, the most priority should be how to reform the way how to change the structural adjustment. If the "structural adjustment" approach, especially in the manufacturing sector can not be changed, many goals on economic transition are likely to fall again. Under the circumstance it is necessary to accelerate the development of a unified, open and orderly modern market system, and effectively implement the market-pushed industrial restructuring approach, and strengthen the intermediary function of finance and inner trade and create good policy environment conducive to promoting the services sector in the process of structural adjustment and industrial upgrading. Key Words:industrial structure; adjustment approach

    He Xinyin as a Confucian Reformer and His Worship of Confucius Abstract:This paper regards He Xinyin, a member of Taizhou School, as a reformer of Confucianism. The reform means to transforming traditional Confucianism which is inti- mately linked with political institution into an independently religious one. The conflicts between Confucian orthodoxy and politics in reality intensified after the Jia.-jing Period in the Ming Dynasty. He Xinyin carries forward his predecessor Wang Xinzhai's theory of "political involvement or retiring from political life", and constructs a set of Confucian in- stitutions, which is independent of politics. On the basis of respects and honors of Confu- cius, He Xinyin~s Confucian institutions enables people to respect and love each other, and makes Confucius~s benevolence and righteousness come true.

    Beliefs and Establishment of Their Orders —— From Sociological Theory Perspectives of Chinese Beliefs LI Xiang-ping Abstract: To understand the "harmonious" phenomena of China's history and culture and their concepts, the key is to understand and recognize its beliefs. Chinese beliefs and their social practice are closely related to establishment of harmonious social, historical and cultural orders in China. In fact, Harmony can refer to either a value target or a social reality, and it is also a kind of belief. The establishment of harmony based on certain beliefs, moral orders, political orders and power orders are basic components of social and cultural harmony. This article, from a sociological theory perspective of beliefs, discusses the positions and roles of different beliefs in building harmonious cultural orders in China, and it then aims to find out some rules of dual changes in Chinese society and Chinese beliefs. Key words: belief; order; harmony; sociological perspectives of belief

It is an ontologicaUy subjective entity and an epistemologically objective judgment. Function ascription is a general form of technical function in the epistemological sense. Function ascriptions may be taken in a descriptive and in a performative sense. The former can be called function ascriptions for short and the latter function assignments. The mind dependency of the function of technical artifacts is grounded in performative function ascriptions instead of descriptive function ascriptions.

    The flue gas flow in entrance of electrostatic precipitator was simulated by Fluent software. Base on the simulation result, a new corona wires arrangement method was proposed for better gas flow distribution. The results indicated that when the corona wires in entrance of two adjacent flues arranged in parallel, the high speed ion airflow occurred in strong electric field would hamper the even distribution of flow, while when the corona wires was staggered arranged, it would benefit to the even distribution of gas flow in precipitator and further improve the dust removal efficiency. This result can provide very important guidance to the transformation and the design of electrostatic precipitator.

    Another Cost of Rights : State Identification and Its Western Experience OU Shujun The Western Experience of State Identification shows that identification is another cost of rights, a prerequisite for constructing the rule of law and good governance. Identification is the most infrastructural public goods that should be supplied by the government, and its publicness comes through in that it almost is a precondition for all state institutions, so it can be called the most infrastructural power of national governance system. In the fourfold-building process of one country under the rule of law, a state rule by law, a tax state, a welfare state and a regulatory state, a modem state increasingly needs to enhance the state identification capacity, so that the majority can be involved in the state identification system, which in turn will accelerate the process of state-building, make law and policies more effective, minimize the intermediate cost of communication between states and individuals, and eventually realize good governance by focusing on the expectations of the majority and serving for the majority. The people seeking a strong democratic country under the rule of law must face up to the fact that identification as a kind of govemmentality has been institutiona/ized and routinized in advanced indnstrial democracies.

    Research on the Theory and Standard of Peasants" Life Cycle Pension Compensation Mu Huaizhong Shen Yi· 2 · Thedifficulties of full coverage in pension system lie in rural farmers. In this paper, we put forward a "dual agricultural welfare difference" theory and apply it to the issues regarding peasants' life cycle pension compensation. Taking differential between equilib- rium and biased agricultural incomes as the key indicator, we build mathematical models of "dual agricultural welfare balance" and measure the size from 1953 to 2009. Our finding shows that China's "dual agricultnral welfare difference" has a fluctuation ranged be- tween 0.4 and 0.6. Based on life cycle characteristics, such as natural life cycle, policy and institutional life cycle, our suggestion is to compensate peasants' primary pension with a balance of "dual agriculture welfare difference" and other countermeasures.

    Fold distribution, offset distribution and azi- muth distribution in a bin have direct effects on ge- ometry attributes in 3D seismic survey design. If two adjacent bins have the same fold but different offsets, this non-uniform offset distribution brings some stack amplitude diversity in the adjacent bins. At present, 3D geometry attribute uniformi- ty of the most analytical methods is expressed by qualitative analysis chart. We introduce in this pa- per a uniformity quantitative analysis method for offset distribution by average value, square devia- tion and weighting factor. The paper analyses effects on offset distribution uniformity of different 3D geometry parameters by the proposed uniformi- ty quantitative analysis method. Furthermore, the paper analyses effects on seismic stack amplitude or frequency uniformity of different 3D geometry parameters by the seismic wave modeling. The re- suits show that offset distribution uniformity is in good agreement with seismic stack amplitude or frequency uniformity. Therefore this improved method can be considered as a useful tool for ana- lyzing and evaluating 3D geometry attribute uni- formity.

    Judicature, Public Opinion, and Politics at An Age of Disordered Legal World View :A Study Centered on the Case of Li Changkui The Case of L/Changkui represents a kind of simple "hard case", in which whatever the judge made a de- cision, result of the case failed to gain good social and legal effects, and the causation, however, rested on the internal system of judicature. The Case of Li reflects an age at which legal world view is deficient in coherence and integration. Although it's not an exclusive problem for China that judicature, public opinion and politics in- teract complicatedly, and the society shows distustt upon the criminal justice system, it reveals that, in the case of Li, some judicial personnel and academics hold an uni-dimensional and prejudiced understanding on the credi- bility, legitimacy and stability of judicature.

    Wu Jie and Duan Yanchao. The current line drawing of Laterolog and its application. PI, 2011, 25(4) : 1 - 4 The current line plays an important role in the directly understanding the characteristics of Laterolog tool. A method of drawing current lines for the discrete potential data based on the Finite Element calculation is studied. It solves a series of key problems, including the selection of step length, the identification of direction, treatment of nmtation point and the control of stop. A drawing program is written by MATLAB software. Taking the current line drawing of the dual Laterolog logging as an example, we analyze the tool's investigation characteristics in the several formations such as homogeneous, low or high invasion, and invasion with shoulder. These results verify the effectiveness of the new method. The method can be applied to the other kinds of Laterolog tools to draw their current lines and analyze their investigation characteristics.

    Sino-Japanese Relations Entering into a New Transitional Period: Discussion on the Choice of Path to Strengthen Mutual Strategic Trusts WU Jinan China and Japan have celebrated the 40th anniversary of the normalization of diplomatic relations with apparently growing discordance. Noticeably, the great progress the two countries achieved in their exchanges and cooperation in all realms in recent years came along with highlighting structural contradictions and antagonism. Lack of mutual strategic confidence between the two countries has become the largest obstacle to the otherwise sound and stable development of the bilateral relations. China and Japan must read and grasp the overall situation of the bilateral relations from a strategic point of view, expand the convergences of their common strategic interests and overcome the estrangement and suspicion between each other, before they will advance Sino-Japanese relations into a new stage.

    Analysis and forecast of the world economy The pace of global economic recovery has slowed down markedly and the risk of a sagging world economy has been increasing in 2011. However, the economic slowdown was taking place at different speeds in different categories of economies. The momentum of economic recovery in the developed economies is clearly insufficient, and its economic growth rate is far lower than the rate of the emerging economies and has declined much more than that of emerging economies. Many big developed economies are facing very severe employment situation now, while the space of the their fiscal and monetary policies have been compressed by the upgrade of the sovereign debt crisis and long-term low interest rates, which are associated with the turmoil in international financial markets, the sluggish growth of international trade and investment, fluctuations in international commodity prices, and aggravated social problems.

  5. Argument structure and the representation of abstract semantics.

    Directory of Open Access Journals (Sweden)

    Javier Rodríguez-Ferreiro

    Full Text Available According to the dual coding theory, differences in the ease of retrieval between concrete and abstract words are related to the exclusive dependence of abstract semantics on linguistic information. Argument structure can be considered a measure of the complexity of the linguistic contexts that accompany a verb. If the retrieval of abstract verbs relies more on the linguistic codes they are associated to, we could expect a larger effect of argument structure for the processing of abstract verbs. In this study, sets of length- and frequency-matched verbs including 40 intransitive verbs, 40 transitive verbs taking simple complements, and 40 transitive verbs taking sentential complements were presented in separate lexical and grammatical decision tasks. Half of the verbs were concrete and half were abstract. Similar results were obtained in the two tasks, with significant effects of imageability and transitivity. However, the interaction between these two variables was not significant. These results conflict with hypotheses assuming a stronger reliance of abstract semantics on linguistic codes. In contrast, our data are in line with theories that link the ease of retrieval with availability and robustness of semantic information.

  7. Relative Ease in Creating Detailed Orthographic Representations Contrasted with Severe Difficulties to Maintain Them in Long-term Memory Among Dyslexic Children.

    Most research into orthographic learning abilities has been conducted in English with typically developing children using reading-based tasks. In the present study, we examined the abilities of French-speaking children with dyslexia to create novel orthographic representations for subsequent use in spelling and to maintain them in long-term memory. Their performance was compared with that of chronological age (CA)-matched and reading age (RA)-matched control children. We used an experimental task designed to provide optimal learning conditions (i.e. 10 spelling practice trials) ensuring the short-term acquisition of the spelling of the target orthographic word forms. After a 1-week delay, the long-term retention of the targets was assessed by a spelling post-test. Analysis of the results revealed that, in the short term, children with dyslexia learned the novel orthographic word forms well, only differing from both CA and RA controls on the initial decoding of the targets and from CA controls on the first two practice trials. In contrast, a dramatic drop was observed in their long-term retention relative to CA and RA controls. These results support the suggestion of the self-teaching hypothesis (Share, 1995) that initial errors in the decoding and spelling of unfamiliar words may hinder the establishment of fully specified novel orthographic representations.

    There exists a remarkable four-qutrit state that carries absolute maximal entanglement in all its partitions. Employing this state, we construct a tensor network that delivers a holographic many body state, the H-code, where the physical properties of the boundary determine those of the bulk. This H-code is made of an even superposition of states whose relative Hamming distances are exponentially large with the size of the boundary. This property makes H-codes natural states for a quantum memory. H-codes exist on tori of definite sizes and get classified in three different sectors characterized by the sum of their qutrits on cycles wrapped through the boundaries of the system. We construct a parent Hamiltonian for the H-code which is highly non local and finally we compute the topological entanglement entropy of the H-code.

The novelty of found solutions was evaluated by the students by rating novelty of each solution on a scale from 1 to 5. Mean values for abstract descriptions were 0,3 higher than for concrete descriptions indicating that more innovative solutions were found when students used...... biocards with abstract descriptions compared to concrete descriptions. The difference in mean value is significant with a confidence level better than 1%.

    A formal technique for incorporating two specification paradigms is presented,in which an algebraic specification is implemented by a set of abstract procedures specified in pre and post-condition style.The link between the two level specifications is provided via a translation from terms of algebraic specifications into temporal logic formulae representing abstract programs.In terms of translation,a criterion for an abstract implementation satisfying its specification is given,which allows one to check the consistency between the two levels of specifications.The abstract implementations can be refined into executable code by refining each abstract procedure in it.It is proved that the satisfication relation between a specification and its implementations is preserved by such refinement steps.

  5. Effect of orthographic processes on letter-identity and letter-position encoding in dyslexic children

    Directory of Open Access Journals (Sweden)

    Caroline eReilhac

    2012-05-01

    Full Text Available The ability to identify letters and encode their position is a crucial step of the word recognition process. However and despite their word identification problem, the ability of dyslexic children to encode letter-identity and letter-position within strings was not systematically investigated. This study aimed at filling this gap and further explored how letter identity and letter position encoding is modulated by letter context in developmental dyslexia. For this purpose, a letter-string comparison task was administered to French dyslexic children and two chronological-age (CA and reading-age (RA-matched control groups. Children had to judge whether two successively and briefly presented 4-letter-strings were identical or different. Letter-position and letter-identity were manipulated through the transposition (e.g., RTGM vs. RMGT or substitution of two letters (e.g., TSHF vs. TGHD. Non-words, pseudo-words and words were used as stimuli to investigate sub-lexical and lexical effects on letter encoding. Dyslexic children showed both substitution and transposition detection problems relative to CA controls. A substitution advantage over transpositions was only found for words in dyslexic children whereas it extended to pseudo-words in RA controls and to all type of items in CA controls. Letters were better identified in the dyslexic group when belonging to orthographically familiar strings. Letter position encoding was very impaired in dyslexic children who did not show any word context effect in contrast to CA controls. Overall, the current findings point to a strong letter identity and letter position encoding disorder in developmental dyslexia.

  6. Orthographic processing deficits in developmental dyslexia: Beyond the ventral visual stream.

    Fast effortless reading has been associated with the Visual Word Form Area (VWFA), a region in the ventral visual stream that specializes in the recognition of letter strings. Several neuroimaging studies of dyslexia revealed an underactivation of this region. However, most of these studies used reading tasks and/or were carried out on adults. Given that fluent reading is severely impaired in dyslexics, any underactivation might simply reflect a well-established reading deficit in impaired readers and could be the consequence rather than the cause of dyslexia. Here, we designed a task that does not rely on reading per se but that tapped early visual orthographic processing that forms the basis of reading. Dyslexic children aged 8-12years and age-matched controls were asked to search for letters, digits, and symbols in 5-element strings (Experiment 1). This novel task was complemented by a classic task known to activate the VWFA, namely the passive viewing of pseudowords and falsefonts (Experiment 2). We found that in addition to significant group differences in the VWFA, dyslexic children showed a significant underactivation of the middle occipital gyrus (MOG) relative to the control group. Several areas in the MOG are known for their engagement in visuospatial processing, and it has been proposed that the MOG is necessary for ordering the symbols in unfamiliar strings. Our results suggest that the VWFA deficit might be secondary to an impairment of visuospatial processing in the MOG. We argue that efficient processing in MOG in the course of reading acquisition is critical for the development of effortless fast visual word recognition in the VWFA. PMID:26774610

    The Abstract Milling problem is a natural and quite general graph-theoretic model for geometric milling problems. Given a graph, one asks for a walk that covers all its vertices with a minimum number of turns, as specified in the graph model by a 0/1 turncost function fx at each vertex x giving, for each ordered pair of edges (e,f) incident at x, the turn cost at x of a walk that enters the vertex on edge e and departs on edge f. We describe an initial study of the parameterized complexity of the problem. Our main positive result shows that Abstract Milling, parameterized by: number of turns, treewidth and maximum degree, is fixed-parameter tractable, We also show that Abstract Milling parameterized by (only) the number of turns and the pathwidth, is hard for W[1] -- one of the few parameterized intractability results for bounded pathwidth.

    2013-01-01

    Elements of Abstract Harmonic Analysis provides an introduction to the fundamental concepts and basic theorems of abstract harmonic analysis. In order to give a reasonably complete and self-contained introduction to the subject, most of the proofs have been presented in great detail thereby making the development understandable to a very wide audience. Exercises have been supplied at the end of each chapter. Some of these are meant to extend the theory slightly while others should serve to test the reader's understanding of the material presented. The first chapter and part of the second give

  13. Abstract communication for coordinated planning

    Clement, Bradley J.; Durfee, Edmund H.

    2003-01-01

    work offers evidence that distributed planning agents can greatly reduce communication costs by reasoning at abstract levels. While it is intuitive that improved search can reduce communication in such cases, there are other decisions about how to communicate plan information that greatly affect communication costs. This paper identifies cases independent of search where communicating at multiple levels of abstraction can exponentially decrease costs and where it can exponentially add costs. We conclude with a process for determining appropriate levels of communication based on characteristics of the domain.

  14. Abstraction processes in artificial grammar learning.

    Shanks, D R; Johnstone, T; Staggs, L

    1997-02-01

    Four experiments explored the extent the extent to which abstract knowledge may underlie subjects' performance when asked to judge the grammaticality of letter strings generated from an artificial grammar. In Experiment 1 and 2 subjects studied grammatical strings instantiated with one set of letters and were then tested on grammatical and ungrammatical strings formed either from the same or a changed letter-set. Even with a change of letter-set, subjects were found to be sensitive to a variety of violation of the grammar. In Experiments 3 and 4, the critical manipulation involved the way in which the training strings were studied: an incidental learning procedure was used for some subjects, and others engaged in an explicit code-breaking task to try to learn the rules of the grammar. When strings were generated from a biconditional (Experiment 4) but not from a standard finite-state grammar (Experiment 3), grammaticality judgements for test strings were independent of their surface similarity to specific studied strings. Overall, the results suggest that transfer in this simple memory task is mediated at least to some extent by abstract knowledge.

    2012-07-01

    Full Text Available Depuis 1900 au moins, la réforme de l’orthographe du français parait être en tout temps une question d’actualité. On ne peut être qu’impressionné par le nombre de commissions, projets, études, publications, pétitions, recommandations officielles... centrés sur cette thématique. L’époque actuelle semble même marquée par une certaine accélération, dont le point de départ pourrait être la publication au Journal officiel français, le 6 décembre 1990, des « rectifications orthographiques ». Toutes les publications scientifiques dédiées à cette question font état des difficultés que rencontrent les francophones dans l’écriture de leur langue. Beaucoup de ces travaux tentent de cerner les proportions respectives des pro- et des antiréformistes, analysent l’argumentaire des uns et des autres, essaient de déterminer sur quelles réformes les attentes pourraient s’accorder. C’est dans cette perspective que le présent travail s’inscrit, dans le contexte de la Belgique francophone. Dans cette communauté, en 1998, quatre circulaires ministérielles sont publiées à l’adresse des enseignants. Elles posent que les nouvelles graphies ont droit de cité dans l’enseignement, tout en mettant en avant un principe de tolérance : ni les nouvelles et ni les anciennes formes ne peuvent être considérées comme fautives. Ces circulaires n’ont apparemment suscité que des réactions assez molles. En septembre 2008, une nouvelle circulaire ministérielle (signée de quatre ministres se montre un peu plus incisive, invitant les enseignants, de tout niveau, à enseigner prioritairement les formes recommandées. La publication de ces circulaires s’est accompagnée de la diffusion, auprès de tous les enseignants, d’un dépliant, publié par le Service de la langue française, 7 Règles pour nous simplifier l’orthographe, qui synthétise les principales règles de la réforme.

  5. Priming of abstract letter representations may be universal: the case of Arabic.

    Science.gov (United States)

    Carreiras, Manuel; Perea, Manuel; Abu Mallouh, Reem

    2012-08-01

    Recent research on the Roman alphabet has demonstrated that the magnitudes of masked repetition priming are equivalent for letter pairs that have similar visual features across cases (e.g., c-C) and for letter pairs with dissimilar features (e.g., g-G). Here, we examined whether priming of abstract letter representations occurs in an orthographic system, Arabic, in which the letters show an intricate number of contextual forms. Arabic does not have a lowercase/uppercase distinction, but the letters exhibit different forms that depend on their position (initial, medial, final, or isolated) and their connectivity. Importantly, some letters look quite different across positions (e.g., (symbol in text) and (symbol in text), which correspond to the letter 'ayn), whereas others look very similar (e.g. (symbol in text), and (symbol in text), which correspond to the letter fā'). We employed a masked priming same-different task, in which native speakers of Arabic decided whether a target letter was the same as or different from a reference letter presented in a different position (middle vs. isolated). The results showed masked repetition priming effects of the same magnitude for letter pairs with similar and with dissimilar visual features across letter positions. These data support the view that priming of abstract letter representations is a universal phenomenon. PMID:22569990

  6. Speech coding

    Energy Technology Data Exchange (ETDEWEB)

    Ravishankar, C., Hughes Network Systems, Germantown, MD

    1998-05-08

    Speech is the predominant means of communication between human beings and since the invention of the telephone by Alexander Graham Bell in 1876, speech services have remained to be the core service in almost all telecommunication systems. Original analog methods of telephony had the disadvantage of speech signal getting corrupted by noise, cross-talk and distortion Long haul transmissions which use repeaters to compensate for the loss in signal strength on transmission links also increase the associated noise and distortion. On the other hand digital transmission is relatively immune to noise, cross-talk and distortion primarily because of the capability to faithfully regenerate digital signal at each repeater purely based on a binary decision. Hence end-to-end performance of the digital link essentially becomes independent of the length and operating frequency bands of the link Hence from a transmission point of view digital transmission has been the preferred approach due to its higher immunity to noise. The need to carry digital speech became extremely important from a service provision point of view as well. Modem requirements have introduced the need for robust, flexible and secure services that can carry a multitude of signal types (such as voice, data and video) without a fundamental change in infrastructure. Such a requirement could not have been easily met without the advent of digital transmission systems, thereby requiring speech to be coded digitally. The term Speech Coding is often referred to techniques that represent or code speech signals either directly as a waveform or as a set of parameters by analyzing the speech signal. In either case, the codes are transmitted to the distant end where speech is reconstructed or synthesized using the received set of codes. A more generic term that is applicable to these techniques that is often interchangeably used with speech coding is the term voice coding. This term is more generic in the sense that the

  7. Object Classification via Planar Abstraction

    Science.gov (United States)

    Oesau, Sven; Lafarge, Florent; Alliez, Pierre

    2016-06-01

    We present a supervised machine learning approach for classification of objects from sampled point data. The main idea consists in first abstracting the input object into planar parts at several scales, then discriminate between the different classes of objects solely through features derived from these planar shapes. Abstracting into planar shapes provides a means to both reduce the computational complexity and improve robustness to defects inherent to the acquisition process. Measuring statistical properties and relationships between planar shapes offers invariance to scale and orientation. A random forest is then used for solving the multiclass classification problem. We demonstrate the potential of our approach on a set of indoor objects from the Princeton shape benchmark and on objects acquired from indoor scenes and compare the performance of our method with other point-based shape descriptors.

  8. Learning abstract algebra with ISETL

    CERN Document Server

    Dubinsky, Ed

    1994-01-01

    Most students in abstract algebra classes have great difficulty making sense of what the instructor is saying. Moreover, this seems to remain true almost independently of the quality of the lecture. This book is based on the constructivist belief that, before students can make sense of any presentation of abstract mathematics, they need to be engaged in mental activities which will establish an experiential base for any future verbal explanation. No less, they need to have the opportunity to reflect on their activities. This approach is based on extensive theoretical and empirical studies as well as on the substantial experience of the authors in teaching astract algebra. The main source of activities in this course is computer constructions, specifically, small programs written in the mathlike programming language ISETL; the main tool for reflections is work in teams of 2-4 students, where the activities are discussed and debated. Because of the similarity of ISETL expressions to standard written mathematics...

  9. Abstract Cauchy problems three approaches

    CERN Document Server

    Melnikova, Irina V

    2001-01-01

    Although the theory of well-posed Cauchy problems is reasonably understood, ill-posed problems-involved in a numerous mathematical models in physics, engineering, and finance- can be approached in a variety of ways. Historically, there have been three major strategies for dealing with such problems: semigroup, abstract distribution, and regularization methods. Semigroup and distribution methods restore well-posedness, in a modern weak sense. Regularization methods provide approximate solutions to ill-posed problems. Although these approaches were extensively developed over the last decades by many researchers, nowhere could one find a comprehensive treatment of all three approaches.Abstract Cauchy Problems: Three Approaches provides an innovative, self-contained account of these methods and, furthermore, demonstrates and studies some of the profound connections between them. The authors discuss the application of different methods not only to the Cauchy problem that is not well-posed in the classical sense, b...

    This thesis presents STO, a software transactional memory (STM) based not on low-level reads and writes on memory, but on datatypes—arrays, lists, queues, hash tables, and so forth—that explicitly support transactional operations. Conventional STMs allow programmers to write concurrent code in much the same way as sequential code—thereby more easily taking advantage of multiple CPU cores. However, these conventional STMs track every memory word accessed during a transaction, so even simple op...

    In order to prove that mathematics cannot be exhausted by a finite set of procedures, Alan Turing conceives, in 1936, of an abstract machine 1. The machine makes its debut in “On Computable Numbers with an application to the Entscheidungsproblem,” his first major mathematical paper 2. A close reading of this machine’s dynamic will show that Turing’s thought in the field of mathematics is a consciously embodied thought that contemplates its own incompleteness. By examining Turing’s machine thr...

    2016-07-01

    Full Text Available An abstract summarizes the accompanying article in order to promote it. While many move-analysis studies of abstracts in applied linguistics (AL have used similar coding frameworks and demonstrated similar rhetorical organizations, their findings have not yet been aggregated to show the overall picture. The present study aimed to both examine move structures in AL abstracts and compare the results with previous studies both synchronically and diachronically. Fifty abstracts were collected from articles published in the journal English for Specific Purposes (ESP between 2011 and 2013. Sentences were coded using a five-move scheme adapted from previous studies. Combining the results from previous research and the present study showed that most AL abstracts give information on the purpose, methodology, and findings of the associated article, while about half of the articles omit introduction of the topic and discussion of the findings. It was also found that authors frequently violate the move sequence expected by current schemes. These findings consistent with previous research suggest that future researchers informed by move analyses should explore the connection between the findings of move analyses and teaching materials for academic writing.

    Many deaf individuals do not develop the high-level reading skills that will allow them to fully take part into society. To attempt to explain this widespread difficulty in the deaf population, much research has honed in on the use of phonological codes during reading.

    International Nuclear Information System (INIS)

    The MCNP code is the major Monte Carlo coupled neutron-photon transport research tool at the Los Alamos National Laboratory, and it represents the most extensive Monte Carlo development program in the United States which is available in the public domain. The present code is the direct descendent of the original Monte Carlo work of Fermi, von Neumaum, and Ulam at Los Alamos in the 1940s. Development has continued uninterrupted since that time, and the current version of MCNP (or its predecessors) has always included state-of-the-art methods in the Monte Carlo simulation of radiation transport, basic cross section data, geometry capability, variance reduction, and estimation procedures. The authors of the present code have oriented its development toward general user application. The documentation, though extensive, is presented in a clear and simple manner with many examples, illustrations, and sample problems. In addition to providing the desired results, the output listings give a a wealth of detailed information (some optional) concerning each state of the calculation. The code system is continually updated to take advantage of advances in computer hardware and software, including interactive modes of operation, diagnostic interrupts and restarts, and a variety of graphical and video aids

    2006-01-01

    The tomographic description of a quantum state is formulated in an abstract infinite dimensional Hilbert space framework, the space of the Hilbert-Schmidt linear operators, with trace formula as scalar product. Resolutions of the unity, written in terms of over-complete sets of rank-one projectors and of associated Gram-Schmidt operators taking into account their non-orthogonality, are then used to reconstruct a quantum state from its tomograms. Examples of well known tomographic descriptions illustrate the exposed theory.

    2013-10-01

    The purpose of this study was to investigate the relationships between writing to dictation, handwriting, orthographic, and perceptual-motor skills among Chinese children with dyslexia. A cross-sectional design was used. A total of 45 third graders with dyslexia were assessed. Results of stepwise multiple regression models showed that Chinese character naming was the only predictor associated with word dictation (β=.32); handwriting speed was related to deficits in rapid automatic naming (β=-.36) and saccadic efficiency (β=-.29), and visual-motor integration predicted both of the number of characters exceeded grid (β=-.41) and variability of character size (β=-.38). The findings provided support to a multi-stage working memory model of writing for explaining the possible underlying mechanism of writing to dictation and handwriting difficulties.

    The current study investigated the time course of cross-linguistic differences in word recognition. We recorded eye movements of German and English children and adults while reading closely matched sentences, each including a target word manipulated for length and frequency. Results showed differential word recognition processes for both developing and skilled readers. Children of the two orthographies did not differ in terms of total word processing time, but this equal outcome was achieved quite differently. Whereas German children relied on small-unit processing early in word recognition, English children applied small-unit decoding only upon rereading-possibly when experiencing difficulties in integrating an unfamiliar word into the sentence context. Rather unexpectedly, cross-linguistic differences were also found in adults in that English adults showed longer processing times than German adults for nonwords. Thus, although orthographic consistency does play a major role in reading development, cross-linguistic differences are detectable even in skilled adult readers.

    Most solutions for detecting buffer overflow are based on source code. But the requirement for source code is not always practical especially for business software. A new approach was presented to detect statically the potential buffer overflow vulnerabilities in the binary code of software. The binary code was translated into assembly code without the lose of the information of string operation functions. The feature code abstract graph was constructed to generate more accurate constraint statements, and analyze the assembly code using the method of integer range constraint. After getting the elementary report on suspicious code where buffer overflows possibly happen, the control flow sensitive analysis using program dependence graph was done to decrease the rate of false positive. A prototype was implemented which demonstrates the feasibility and efficiency of the new approach.

    Full Text Available Resumen: El estudio de la ortografía resulta a veces tan árido para los alumnos como desalentador para los profesores. El desánimo cunde por la sensación de enfrentarse a un enmarañado reglamento. Sin embargo, la ortografía se puede estructurar a fin de discernir sus problemas concretos y así poder superarlos más fácilmente. Nuestroproyecto presenta un método claro para detectar esos problemas ortográficos. Para ello hemos diseñado un “Informe sobre problemas ortográficos detectados”, una plantilla personalizada y diacrónica en la que aparecen, estructurados, los problemas ortográficos más habituales que el profesor debe detectar y señalar. Ese documento remite decimalmente a un sencillo y práctico “Resumen de las reglas ortográficas”.Summary: The study of spelling is sometimes as arid for the pupils as discouraging for the teachers. The sensation of facing an entangled regulation causes discouragement. However, spelling rules can be structured in order to discern the specific problems more easily. Our project presents a clear method to detect orthographic problems. Withthis purpose, we have designed a "Report on spelling problems detected", a personalized report containing the most habitual orthographic problems that the teacher must detect. This document refers to a practical and simple "Summary of spelling rules".

Most research focused on the perspective of cognition and empirical approaches, while little research has highlighted the perspective of application. Research has indicated that recognition of the orthographies of Chinese characters is the key to learn Chinese. But the abstract Chinese's orthographic knowledge can't be directly taught because of children's undeveloped cognitive ability. Chinese learning combined with pictures is one of the most popular methods to be used. However, it is not quite clear how strong the auxiliary function is. Dongba pictograph has similar characteristics of Chinese characters and pictures to some extent. It is suggested that Dongba pictograph may contribute to children

    Most theories of reading and writing posit a level of representation that codes abstract letter identities (ALIs) independent of the font, case, and even modality in which the letter was presented or produced (e.g., Caramazza & Hillis, 1990). Most cognitive theories assume that ALIs are critical for mediating between peripheral (e.g., processing visual shapes, executing motor plans) and central (e.g., accessing semantic or lexical information) written language processes.

  10. Tools and Behavior Abstraction: A Future for Software Engineering

    Directory of Open Access Journals (Sweden)

    2012-06-01

    Full Text Available Software engineers rely on and use tools to analyze automatically and detailed the code and design specifications. Although many are still used to find new defects in old code, is expected in the future have more application in software engineering and are available to developers at the time of editing their products. If were possible build them fast enough and easy to use, software engineers would apply it to improve design and product development. To solve any problem, traditional engineering use programming languages, however, the level of abstraction of the most popular is not much larger than C programs several decades ago. Moreover, this level is the same in all the code and do not leaves room for abstraction of behavior, in which the design is divided into phases and which gradually introduces more details. This article presents a study of the need for a larger set of analysis tools to create languages and development environments, which provide good support to archive this abstraction.

  11. Does location uncertainty in letter position coding emerge because of literacy training?

    Science.gov (United States)

    Perea, Manuel; Jiménez, María; Gomez, Pablo

    2016-06-01

    In the quest to unveil the nature of the orthographic code, a useful strategy is to examine the transposed-letter effect (e.g., JUGDE is more confusable with its base word, JUDGE, than the replacement-letter nonword JUPTE). A leading explanation of this phenomenon, which is line with models of visual attention, is that there is perceptual uncertainty at assigning letters ("objects") to positions. This mechanism would be at work not only with skilled readers but also with preliterate children. An alternative explanation is that the transposed-letter effect emerges at an orthographic level of processing as a direct consequence of literacy training. To test these accounts, we conducted a same-different matching experiment with preliterate 4-year-old children using same versus different trials (created by letter transposition or replacement). Results showed a significantly larger number of false positives (i.e., "same" responses) to transposed-letter strings than to 1/2 replacement-letter strings. Therefore, the present data favor the view that the visual processing of location information is inherently noisy and rule out an interpretation of confusability in letter position coding as emerging from literacy training.

  13. Abstract Expression Grammar Symbolic Regression

    Science.gov (United States)

    Korns, Michael F.

    This chapter examines the use of Abstract Expression Grammars to perform the entire Symbolic Regression process without the use of Genetic Programming per se. The techniques explored produce a symbolic regression engine which has absolutely no bloat, which allows total user control of the search space and output formulas, which is faster, and more accurate than the engines produced in our previous papers using Genetic Programming. The genome is an all vector structure with four chromosomes plus additional epigenetic and constraint vectors, allowing total user control of the search space and the final output formulas. A combination of specialized compiler techniques, genetic algorithms, particle swarm, aged layered populations, plus discrete and continuous differential evolution are used to produce an improved symbolic regression sytem. Nine base test cases, from the literature, are used to test the improvement in speed and accuracy. The improved results indicate that these techniques move us a big step closer toward future industrial strength symbolic regression systems.

    A kind of novel binary phase code named sidelobe suppression code is proposed in this paper. It is defined to be the code whose corresponding optimal sidelobe suppression filter outputs the minimum sidelobes. It is shown that there do exist sidelobe suppression codes better than the conventional optimal codes-Barker codes. For example, the sidelobe suppression code of length 11 with filter of length 39 has better sidelobe level up to 17dB than that of Barker code with the same code length and filter length.

    2012-07-01

    Full Text Available Le discours ordinaire sur l’orthographe française que l’on observe dans les espaces publics et que l’on recueille dans les enquêtes scientifiques est constitué habituellement de stéréotypes. Ces représentations sociales sur l’orthographe, souvent peu fondées scientifiquement, mettent au jour une orthographe du français complexe et difficile devenant ainsi une source de problèmes pour ceux qui souhaitent l’acquérir ou la maitriser. Pourtant, la question de l’orthographe représente un véritable enjeu social. En effet, le niveau de littéracie, c’est-à-dire les capacités de lecture et d’écriture, est déterminant pour l’insertion sociale et professionnelle. Nous savons à présent que les difficultés orthographiques représentent, et ce tout particulièrement en France, un obstacle à la satisfaction des attentes scolaires, et elles constituent vraisemblablement un frein à l’insertion professionnelle. Toutefois, il suffit d’aborder la question d’une réforme de l’orthographe du français pour déclencher des levées de boucliers dans la sphère publique et des débats passionnés entre esthètes de la langue française. Mais qu’en pense le monde enseignant, vecteur de la norme ? Cette communication s’appuie sur une enquête internationale, menée dans six pays francophones, qui cherchait à déterminer quels étaient les besoins et les attentes des francophones en matière d’orthographe. Cette recherche fut conduite par le groupe RO constitué de chercheurs venus de ces six pays, auprès d’un échantillon de 1738 enseignants et futurs enseignants. Un questionnaire d’une soixantaine de questions leur a été diffusé, et a permis de recueillir leurs opinions et leurs représentations au sujet de l’orthographe et d’une éventuelle réforme.

  3. Attracting Girls into Physics (abstract)

    2009-04-01

    A recent international study of women in physics showed that enrollment in physics and science is declining for both males and females and that women are severely underrepresented in careers requiring a strong physics background. The gender gap begins early in the pipeline, from the first grade. Girls are treated differently than boys at home and in society in ways that often hinder their chances for success. They have fewer freedoms, are discouraged from accessing resources or being adventurous, have far less exposure to problem solving, and are not encouraged to choose their lives. In order to motivate more girl students to study physics in the Assiut governorate of Egypt, the Assiut Alliance for the Women and Assiut Education District collaborated in renovating the education of physics in middle and secondary school classrooms. A program that helps in increasing the number of girls in science and physics has been designed in which informal groupings are organized at middle and secondary schools to involve girls in the training and experiences needed to attract and encourage girls to learn physics. During implementation of the program at some schools, girls, because they had not been trained in problem-solving as boys, appeared not to be as facile in abstracting the ideas of physics, and that was the primary reason for girls dropping out of science and physics. This could be overcome by holding a topical physics and technology summer school under the supervision of the Assiut Alliance for the Women.

  4. An abstract approach to music.

    Energy Technology Data Exchange (ETDEWEB)

    Kaper, H. G.; Tipei, S.

    1999-04-19

    In this article we have outlined a formal framework for an abstract approach to music and music composition. The model is formulated in terms of objects that have attributes, obey relationships, and are subject to certain well-defined operations. The motivation for this approach uses traditional terms and concepts of music theory, but the approach itself is formal and uses the language of mathematics. The universal object is an audio wave; partials, sounds, and compositions are special objects, which are placed in a hierarchical order based on time scales. The objects have both static and dynamic attributes. When we realize a composition, we assign values to each of its attributes: a (scalar) value to a static attribute, an envelope and a size to a dynamic attribute. A composition is then a trajectory in the space of aural events, and the complex audio wave is its formal representation. Sounds are fibers in the space of aural events, from which the composer weaves the trajectory of a composition. Each sound object in turn is made up of partials, which are the elementary building blocks of any music composition. The partials evolve on the fastest time scale in the hierarchy of partials, sounds, and compositions. The ideas outlined in this article are being implemented in a digital instrument for additive sound synthesis and in software for music composition. A demonstration of some preliminary results has been submitted by the authors for presentation at the conference.

    Full Text Available Studies examining reading development in bilinguals have led to conflicting conclusions regarding the language in which reading development should take place first. Whereas some studies suggest that reading instruction should take place in the most proficient language first, other studies suggest that reading acquisition should take place in the most consistent orthographic system first. The present study examined two research questions: (1 the relative impact of oral proficiency and orthographic transparency in second-language reading acquisition, and (2 the influence of reading acquisition in one language on the development of reading skills in the other language. To examine these questions, we compared reading development in French-native children attending a Dutch immersion program and learning to read either in Dutch first (most consistent orthography or in French first (least consistent orthography but native language. Following a longitudinal design, the data were gathered over different sessions spanning from Grade 1 to Grade 3. The children in immersion were presented with a series of experimental and standardised tasks examining their levels of oral proficiency as well as their reading abilities in their first and, subsequently in their second, languages of reading instruction. Their performances were compared to the ones of French and Dutch monolinguals. The results showed that by the end of Grade 2, the children instructed to read in Dutch first read in both languages as well as their monolingual peers. In contrast, the children instructed to read in French first lagged behind the other Dutch-speaking groups in Dutch reading tasks. These findings extend the notion that differences across languages in terms of orthographic transparency impact on reading development to the French-Dutch pair, and strongly support the view that there are potentially significant benefits to learn to read in the most consistent orthographic system first

    2007-02-01

    Full Text Available Abstract Background Comparative genomics approaches, where orthologous DNA regions are compared and inter-species conserved regions are identified, have proven extremely powerful for identifying non-coding regulatory regions located in intergenic or intronic regions. However, non-coding functional elements can also be located within coding region, as is common for exonic splicing enhancers, some transcription factor binding sites, and RNA secondary structure elements affecting mRNA stability, localization, or translation. Since these functional elements are located in regions that are themselves highly conserved because they are coding for a protein, they generally escaped detection by comparative genomics approaches. Results We introduce a comparative genomics approach for detecting non-coding functional elements located within coding regions. Codon evolution is modeled as a mixture of codon substitution models, where each component of the mixture describes the evolution of codons under a specific type of coding selective pressure. We show how to compute the posterior distribution of the entropy and parsimony scores under this null model of codon evolution. The method is applied to a set of growth hormone 1 orthologous mRNA sequences and a known exonic splicing elements is detected. The analysis of a set of CORTBP2 orthologous genes reveals a region of several hundred base pairs under strong non-coding selective pressure whose function remains unknown. Conclusion Non-coding functional elements, in particular those involved in post-transcriptional regulation, are likely to be much more prevalent than is currently known. With the numerous genome sequencing projects underway, comparative genomics approaches like that proposed here are likely to become increasingly powerful at detecting such elements.

  9. Annotating user-defined abstractions for optimization

    Quinlan, D; Schordan, M; Vuduc, R; Yi, Q

    2005-12-05

    This paper discusses the features of an annotation language that we believe to be essential for optimizing user-defined abstractions. These features should capture semantics of function, data, and object-oriented abstractions, express abstraction equivalence (e.g., a class represents an array abstraction), and permit extension of traditional compiler optimizations to user-defined abstractions. Our future work will include developing a comprehensive annotation language for describing the semantics of general object-oriented abstractions, as well as automatically verifying and inferring the annotated semantics.

    Abstraction is the key when learning behavioral models of realistic systems. Hence, in most practical applications where automata learning is used to construct models of software components, researchers manually define abstractions which, depending on the history, map a large set of concrete events...... are allowed. Our approach uses counterexample-guided abstraction refinement: whenever the current abstraction is too coarse and induces nondeterministic behavior, the abstraction is refined automatically. Using Tomte, a prototype tool implementing our algorithm, we have succeeded to learn – fully...

    Dare, Natasha; Shillcock, Richard

    2013-01-01

    We present a novel lexical decision task and three boundary paradigm eye-tracking experiments that clarify the picture of parallel processing in word recognition in context. First, we show that lexical decision is facilitated by associated letter information to the left and right of the word, with no apparent hemispheric specificity. Second, we show that parafoveal preview of a repeat of word n at word n + 1 facilitates reading of word n relative to a control condition with an unrelated word at word n + 1. Third, using a version of the boundary paradigm that allowed for a regressive eye movement, we show no parafoveal "postview" effect on reading word n of repeating word n at word n - 1. Fourth, we repeat the second experiment but compare the effects of parafoveal previews consisting of a repeated word n with a transposed central bigram (e.g., caot for coat) and a substituted central bigram (e.g., ceit for coat), showing the latter to have a deleterious effect on processing word n, thereby demonstrating that the parafoveal preview effect is at least orthographic and not purely visual.

    Full Text Available Recently, we identified a hierarchy relation between trinucleotide comma-free codes and trinucleotide circular codes (see our previous works. Here, we extend our hierarchy with two new classes of codes, called DLD and LDL codes, which are stronger than the comma-free codes. We also prove that no circular code with 20 trinucleotides is a DLD code and that a circular code with 20 trinucleotides is comma-free if and only if it is a LDL code. Finally, we point out the possible role of the symmetric group ∑4 in the mathematical study of trinucleotide circular codes.

  7. Test Input Generation for Red-Black Trees using Abstraction

    Visser, Willem; Pasareanu, Corina S.; Pelanek, Radek

    2005-01-01

    We consider the problem of test input generation for code that manipulates complex data structures. Test inputs are sequences of method calls from the data structure interface. We describe test input generation techniques that rely on state matching to avoid generation of redundant tests. Exhaustive techniques use explicit state model checking to explore all the possible test sequences up to predefined input sizes. Lossy techniques rely on abstraction mappings to compute and store abstract versions of the concrete states; they explore under-approximations of all the possible test sequences. We have implemented the techniques on top of the Java PathFinder model checker and we evaluate them using a Java implementation of red-black trees.

    Based on the encoding process, arithmetic codes can be viewed as tree codes and current proposals for decoding arithmetic codes with forbidden symbols belong to sequential decoding algorithms and their variants. In this monograph, we propose a new way of looking at arithmetic codes with forbidden symbols. If a limit is imposed on the maximum value of a key parameter in the encoder, this modified arithmetic encoder can also be modeled as a finite state machine and the code generated can be treated as a variable-length trellis code. The number of states used can be reduced and techniques used fo

    2009-01-01

    Abstractions are used in model checking to tackle problems like state space explosion or modeling of IO. The application of these abstractions in real software development processes, however, lacks engineering support. This is one reason why model checking is not widely used in practice yet and testing is still state of the art in falsification. We show how user-defined abstractions can be integrated into a Java PathFinder setting with tools like AspectJ or Javassist and discuss implicati...

  10. Analysis of complex networks using aggressive abstraction.

    Energy Technology Data Exchange (ETDEWEB)

    Colbaugh, Richard; Glass, Kristin.; Willard, Gerald

    2008-10-01

    This paper presents a new methodology for analyzing complex networks in which the network of interest is first abstracted to a much simpler (but equivalent) representation, the required analysis is performed using the abstraction, and analytic conclusions are then mapped back to the original network and interpreted there. We begin by identifying a broad and important class of complex networks which admit abstractions that are simultaneously dramatically simplifying and property preserving we call these aggressive abstractions -- and which can therefore be analyzed using the proposed approach. We then introduce and develop two forms of aggressive abstraction: 1.) finite state abstraction, in which dynamical networks with uncountable state spaces are modeled using finite state systems, and 2.) onedimensional abstraction, whereby high dimensional network dynamics are captured in a meaningful way using a single scalar variable. In each case, the property preserving nature of the abstraction process is rigorously established and efficient algorithms are presented for computing the abstraction. The considerable potential of the proposed approach to complex networks analysis is illustrated through case studies involving vulnerability analysis of technological networks and predictive analysis for social processes.

  11. Injecting Abstract Interpretations into Linear Cost Models

    Directory of Open Access Journals (Sweden)

    David Cachera

    2010-06-01

    Full Text Available We present a semantics based framework for analysing the quantitative behaviour of programs with regard to resource usage. We start from an operational semantics equipped with costs. The dioid structure of the set of costs allows for defining the quantitative semantics as a linear operator. We then present an abstraction technique inspired from abstract interpretation in order to effectively compute global cost information from the program. Abstraction has to take two distinct notions of order into account: the order on costs and the order on states. We show that our abstraction technique provides a correct approximation of the concrete cost computations.

  13. Accurate discrimination of conserved coding and non-coding regions through multiple indicators of evolutionary dynamics

    Directory of Open Access Journals (Sweden)

    2009-09-01

    Full Text Available Abstract Background The conservation of sequences between related genomes has long been recognised as an indication of functional significance and recognition of sequence homology is one of the principal approaches used in the annotation of newly sequenced genomes. In the context of recent findings that the number non-coding transcripts in higher organisms is likely to be much higher than previously imagined, discrimination between conserved coding and non-coding sequences is a topic of considerable interest. Additionally, it should be considered desirable to discriminate between coding and non-coding conserved sequences without recourse to the use of sequence similarity searches of protein databases as such approaches exclude the identification of novel conserved proteins without characterized homologs and may be influenced by the presence in databases of sequences which are erroneously annotated as coding. Results Here we present a machine learning-based approach for the discrimination of conserved coding sequences. Our method calculates various statistics related to the evolutionary dynamics of two aligned sequences. These features are considered by a Support Vector Machine which designates the alignment coding or non-coding with an associated probability score. Conclusion We show that our approach is both sensitive and accurate with respect to comparable methods and illustrate several situations in which it may be applied, including the identification of conserved coding regions in genome sequences and the discrimination of coding from non-coding cDNA sequences.

  14. Reading scripts that differ in orthographic transparency: a within-participant-and-language investigation of underlying skills.

    Spelling-sound transparency varies across orthographies. This aspect was found to have implications for the strategy of reading, but whether reading of different orthographies also relies differently on cognitive skills is yet unclear. This question was examined mainly by cross-participant-and-language investigations in which orthographic variation is hard to isolate. This work examined this topic using a within-participant-and-language study design. Hebrew readers in Grades 3 and 4 were longitudinally tested because in these grades they are engaged in reading three forms of script, transcribing the same language and varying in spelling-sound relations, as they gradually progress from reading a transparent orthography to reading an opaque one. Phonological awareness explained a considerable amount of variance in accuracy in reading all forms of script across these two years. The relations of morphological awareness with accuracy in reading the three forms of script were similar; however, the results suggested that these may be associated with the course of transition. Phonological awareness and rapid naming were similarly related to fluency in reading all forms of script when equivalent proficiencies in reading of these scripts were achieved. At this stage, the relations of vocabulary with fluency in reading and comprehension of the transparent and opaque forms of script were also much alike. Phonological memory explained a modest, but significant, amount of variance in comprehension of the unpointed script alone. These results suggest that, apart from phonological memory, the cognitive skills tested in this study serve as a common cognitive infrastructure in reading orthographies varying in spelling-sound transparency.

    We present several results on quantum codes over general alphabets (that is, in which the fundamental units may have more than 2 states). In particular, we consider codes derived from finite symplectic geometry assumed to have additional global symmetries. From this standpoint, the analogues of Calderbank-Shor-Steane codes and of GF(4)-linear codes turn out to be special cases of the same construction. This allows us to construct families of quantum codes from certain codes over number fields...

    Full Text Available We present a new class of alternating codes. Instead of the customary binary phase codes, the new codes utilize either p or p–1 phases, where p is a prime number. The first class of codes has code length pm, where m is a positive integer, the second class has code length p–1. We give an actual construction algorithm, and explain the principles behind it. We handle a few specific examples in detail. The new codes offer an enlarged collection of code lengths for radar experiments.

    2004-10-21

    The purpose of this report is to document the abstraction model being used in total system performance assessment (TSPA) model calculations for radionuclide transport in the unsaturated zone (UZ). The UZ transport abstraction model uses the particle-tracking method that is incorporated into the finite element heat and mass model (FEHM) computer code (Zyvoloski et al. 1997 [DIRS 100615]) to simulate radionuclide transport in the UZ. This report outlines the assumptions, design, and testing of a model for calculating radionuclide transport in the UZ at Yucca Mountain. In addition, methods for determining and inputting transport parameters are outlined for use in the TSPA for license application (LA) analyses. Process-level transport model calculations are documented in another report for the UZ (BSC 2004 [DIRS 164500]). Three-dimensional, dual-permeability flow fields generated to characterize UZ flow (documented by BSC 2004 [DIRS 169861]; DTN: LB03023DSSCP9I.001 [DIRS 163044]) are converted to make them compatible with the FEHM code for use in this abstraction model. This report establishes the numerical method and demonstrates the use of the model that is intended to represent UZ transport in the TSPA-LA. Capability of the UZ barrier for retarding the transport is demonstrated in this report, and by the underlying process model (BSC 2004 [DIRS 164500]). The technical scope, content, and management of this report are described in the planning document ''Technical Work Plan for: Unsaturated Zone Transport Model Report Integration'' (BSC 2004 [DIRS 171282]). Deviations from the technical work plan (TWP) are noted within the text of this report, as appropriate. The latest version of this document is being prepared principally to correct parameter values found to be in error due to transcription errors, changes in source data that were not captured in the report, calculation errors, and errors in interpretation of source data.

  13. Verification of Statecharts Using Data Abstraction

    Directory of Open Access Journals (Sweden)

    Steffen Helke

    2016-01-01

    Full Text Available We present an approach for verifying Statecharts including infinite data spaces. We devise a technique for checking that a formula of the universal fragment of CTL is satisfied by a specification written as a Statechart. The approach is based on a property-preserving abstraction technique that additionally preserves structure. It is prototypically implemented in a logic-based framework using a theorem prover and a model checker. This paper reports on the following results. (1 We present a proof infra-structure for Statecharts in the theorem prover Isabelle/HOL, which constitutes a basis for defining a mechanised data abstraction process. The formalisation is based on Hierar-chical Automata (HA which allow a structural decomposition of Statecharts into Sequential Automata. (2 Based on this theory we introduce a data abstraction technique, which can be used to abstract the data space of a HA for a given abstraction function. The technique is based on constructing over-approximations. It is structure-preserving and is designed in a compositional way. (3 For reasons of practicability, we finally present two tactics supporting the abstraction that we have implemented in Isabelle/HOL.

    Backward induction is a benchmark of game theoretic rationality, yet surprisingly little is known as to how humans discover and initially learn to apply this abstract solution concept in experimental settings. We use behavioral and functional magnetic resonance imaging (fMRI) data to study the way in which subjects playing in a sequential game of perfect information learn the optimal backward induction strategy for the game. Experimental data from our two studies support two main findings: First, subjects converge to a common process of recursive inference similar to the backward induction procedure for solving the game. The process is recursive because earlier insights and conclusions are used as inputs in later steps of the inference. This process is matched by a similar pattern in brain activation, which also proceeds backward, following the prediction error: brain activity initially codes the responses to losses in final positions; in later trials this activity shifts to the starting position. Second, the learning process is not exclusively cognitive, but instead combines experience-based learning and abstract reasoning. Critical experiences leading to the adoption of an improved solution strategy appear to be stimulated by brain activity in the reward system. This indicates that the negative affect induced by initial failures facilitates the switch to a different method of solving the problem. Abstract reasoning is combined with this response, and is expressed by activation in the ventrolateral prefrontal cortex. Differences in brain activation match differences in performance between subjects who show different learning speeds.

    A sample driven description of Research Article-Comment-Reply (RA-C-R) abstracts in terms of abstract sentence length, reference, possessive structures, modal verbs and word range was carried out to find out whether their surface text features showed some trace of a dialogical construction of knowledge within the psychology discourse community. The study served an exploratory purpose. A Boolean search was conducted in the PsycLIT database yielding a sample of 149 PsycLIT RA-C-R abstracts (13,...

  18. Engineering Abstractions in Model Checking and Testing

    Abstractions are used in model checking to tackle problems like state space explosion or modeling of IO. The application of these abstractions in real software development processes, however, lacks engineering support. This is one reason why model checking is not widely used in practice yet...... and testing is still state of the art in falsification. We show how user-defined abstractions can be integrated into a Java PathFinder setting with tools like AspectJ or Javassist and discuss implications of remaining weaknesses of these tools. We believe that a principled engineering approach to designing...

  19. Contracts for Abstract Processes in Service Composition

    Full Text Available Contracts are a well-established approach for describing and analyzing behavioral aspects of web service compositions. The theory of contracts comes equipped with a notion of compatibility between clients and servers that ensures that every possible interaction between compatible clients and servers will complete successfully. It is generally agreed that real applications often require the ability of exposing just partial descriptions of their behaviors, which are usually known as abstract processes. We propose a formal characterization of abstraction as an extension of the usual symbolic bisimulation and we recover the notion of abstraction in the context of contracts.

  20. Chemical information science coverage in Chemical Abstracts.

    For many years Chemical Abstracts has included in its coverage publications on chemical documentation or chemical information science. Although the bulk of those publications can be found in section 20 of Chemical Abstracts, many relevant articles were found scattered among 39 other sections of CA in 1984-1985. In addition to the scattering of references in CA, the comprehensiveness of Chemical Abstracts as a secondary source for chemical information science is called into question. Data are provided on the journals that contributed the most references on chemical information science and on the languages of publication of relevant articles.
