    Purpose. To construct and validate a test of sustained silent reading. Methods. Standardized 7300 and 7600 word passages were written to evaluate sustained silent reading. Two hundred forty subjects validated whether comprehension questions could discriminate subjects who did and did not read the passage. To evaluate test–retest properties, 49 subjects silently read the standardized passages on separate days. Sixty glaucoma suspect controls and 64 glaucoma subjects had their out loud reading evaluated with the MNRead card and an International Reading Speed Texts (IReST) passage, and their silent reading measured using the 7300 word passage. Sustained silent reading parameters included reading speed and reading speed slope over time. Results. Comprehension questions distinguished individuals who had and had not read passage materials. Bland-Altman analyses of intersession sustained reading speed and reading speed slope demonstrated 95% coefficients of repeatability of 57 words per minute (wpm) and 2.76 wpm/minute. Sustained silent reading speed was less correlated with MNRead (r = 0.59) or IReST passage (r = 0.68) reading speeds than the correlation of these two measures of out loud reading speed with each other (r = 0.72). Sustained silent reading speed was more likely to differ from IReST reading speed by more than 50% in rapid silent readers (odds ratio [OR] = 29, 95% confidence interval [CI] = 10–87), and comparisons of sustained and out loud reading speeds demonstrated proportional error in Bland-Altman analyses. Conclusions. Tests of out loud reading do not accurately reflect silent reading speed in individuals with normal vision or glaucoma. The described test offers a standardized way to evaluate the impact of eye disease and/or visual rehabilitation on sustained silent reading. PMID:23258146

    Many studies have examined reading and reading development. The majority of these studies, however, focused on oral reading rather than on the more dominant silent reading mode. Similarly, it is common practice to assess oral reading abilities rather than silent reading abilities in schools and in diagnosis of reading impairments. More important, insights gained through examinations of oral reading tend to be generalized to silent reading. In the current study, we examined whether such generalizations are justified. We directly compared oral and silent reading fluency by examining whether these reading modes relate to the same underlying skills. In total, 132 fourth graders read words, sentences, and text orally, and 123 classmates read the same material silently. As underlying skills, we considered phonological awareness, rapid naming, and visual attention span. All skills correlated significantly with both reading modes. Phonological awareness contributed equally to oral and silent reading. Rapid naming, however, correlated more strongly with oral reading than with silent reading. Visual attention span correlated equally strongly with both reading modes but showed a significant unique contribution only to silent reading. In short, we showed that oral and silent reading indeed are fairly similar reading modes, based on the relations with reading-related cognitive skills. However, we also found differences that warrant caution in generalizing findings across reading modes. Copyright © 2014 Elsevier Inc. All rights reserved.

  11. Eye Movement during Silent and Oral Reading: How Can we Compensate the Loss of Multisensory Process during Silent Reading?

    Full Text Available While reading texts orally, we process the multisensory language information. Accordingly, in the context of reading aloud, we process the visually presented text and produce the auditory information of the text through articulatory movement. These multisensory processing activities are assumed to facilitate the memory and comprehension of textual information. Conversely, while reading silently, we process only the visual information of the text. Although we cannot use the multisensory language information while reading silently, several researchers have found that there is little difference between the degree of comprehension based on silent and oral reading for adult readers. The purpose of this study is to explain how we compensate the loss of multisensory process during silent reading by comparing the visual processing process during silent and oral reading. By conducting two experiments, we measured and compared the eye movement during silent and oral reading. The results showed that silent reading took shorter time for comprehension than oral reading, and readers had more visual fixation points and read back frequently during reading silently than orally. These reading strategies during silent reading seemed to compensate the loss of multisensory process and support the text comprehension.

  12. Does silent reading involve articulation? Evidence from tongue twisters.

    To demonstrate an interfering effect of subvocal articulation on otherwise silent reading, college-student subjects were asked to repeatedly read, either silently or aloud, both tongue-twister sentences and control sentences matched for syntactic complexity, syllable count, and sentential stress pattern. A technique was developed to measure the amount of time needed for each repetition of a sentence whether done silently or aloud. A significant difference in reading time for tongue twisters as compared to their matched controls was found for both silent as well as out-loud reading. A variety of different kinds of articulatory errors occurred in the oral repetitions, and the number of such errors was highly correlated with oral reading time. While errors could not be measured in silent reading, this correlation suggested that comparable articulatory disturbances accounted for the slower time to silently repeat tongue twisters.

This attitude is related to an individual’s acquired level of the rational silent reading. The author has been interested in the problem of rational silent reading for 35 years. In the empirical research and experiments there took part more than 500 pupils, students, teachers, employees of different spheres, secondary schools graduates. From the point of view of rational silent reading Lithuania is significantly lagging behind other countries. There are many reasons for that. In order to highlight them there has been briefly studied the content of the rational silent reading according to B2 level; touched on the most significant dimensions of this competency, reviewed the consistent patterns and content of the teaching and learning process of the rational silent reading as well as the norms of such reading in Lithuanian, English, Russian, French. Some research results are presented. At the end there has been given the whole mosaic of recommendations, based on the research, different glottoeducological, psychological, psycholinguistic, physiological, linguistic, etc literature. The aim of the article is to invite teachers, scientists to participate actively in this problem solution under the new Lithuanian conditions.

  1. Assessing reading fluency in Kenya: Oral or silent assessment?

    Piper, Benjamin; Zuilkowski, Stephanie Simmons

    2015-04-01

    In recent years, the Education for All movement has focused more intensely on the quality of education, rather than simply provision. Many recent and current education quality interventions focus on literacy, which is the core skill required for further academic success. Despite this focus on the quality of literacy instruction in developing countries, little rigorous research has been conducted on critical issues of assessment. This analysis, which uses data from the Primary Math and Reading Initiative (PRIMR) in Kenya, aims to begin filling this gap by addressing a key assessment issue - should literacy assessments in Kenya be administered orally or silently? The authors compared second-grade students' scores on oral and silent reading tasks of the Early Grade Reading Assessment (EGRA) in Kiswahili and English, and found no statistically significant differences in either language. They did, however, find oral reading rates to be more strongly related to reading comprehension scores. Oral assessment has another benefit for programme evaluators - it allows for the collection of data on student errors, and therefore the calculation of words read correctly per minute, as opposed to simply words read per minute. The authors therefore recommend that, in Kenya and in similar contexts, student reading fluency be assessed via oral rather than silent assessment.

  2. Silent Revolution in Research for Sustainability

    Directory of Open Access Journals (Sweden)

    2016-06-01

    Full Text Available Is research ‘fit-for-purpose’ for realizing sustainable development? More than two decades after the Brundtland report and UNCED Earth summit, the world has now adopted Sustainable Development Goals(SDGs. Rather than a cause for celebration, this delay should encourage reflection on the role of research in society. Why is it so difficult to realize sustainability in practice? The answer lies in the fact that universities and research centres persist with 19th century methods of data gathering, scholarly analysis, and journal articles. Today’s world needs science in real-time, whether to detect drought, confront Ebola, or assist refugees. Research needs to work faster and embrace 21st century practices including data science, open access, and infographics.A silent revolution is occurring in the ways of organizing and conducting research, enabled by new technology and encouraging work that tackles the key challenges facing society. A variety of new arrangements have come into existence that promote international collaboration, including Horizon 2020 with its emphasis on societal challenges, the Bill & Melinda Gates Foundation which has inspired a family of grand challenges funds on health and development, and the Future Earth joint program of research for global sustainability. These arrangements not only control billions of dollars in research funding, they also influence the strategies of national research councils and international organizations. The result is no less than a transformation in the incentives that reward how researchers invest their time and effort.Why is a revolution needed? Within research, substantial growth in knowledge production coincided with fragmentation among disciplines. One can easily find expertise and publications in soil science or agronomy, yet integrated efforts on food security and climate adaptation remain scarce. Beyond research, society remains largely uninformed, as academics avoid engaging in public

    2016-01-01

    This paper focuses on reading fluency by bilingual primary school students, and the relation of text fluency to their reading comprehension. Group differences were examined in a cross-sectional design across the age range when fluency is posed to shift from word-level to text-level. One hundred five bilingual children from primary grades 3, 4, and 5 were assessed for English word reading and decoding fluency, phonological awareness, rapid symbol naming, and oral language proficiency with standardized measures. These skills were correlated with their silent reading fluency on a self-paced story reading task. Text fluency was quantified using non-linear analytic methods: recurrence quantification and fractal analyses. Findings indicate that more fluent text reading appeared by grade 4, similar to monolingual findings, and that different aspects of fluency characterized passage reading performance at different grade levels. Text fluency and oral language proficiency emerged as significant predictors of reading comprehension. PMID:27630590

  5. Inner speech during silent reading reflects the reader's regional accent.

    Directory of Open Access Journals (Sweden)

    Ruth Filik

    Full Text Available While reading silently, we often have the subjective experience of inner speech. However, there is currently little evidence regarding whether this inner voice resembles our own voice while we are speaking out loud. To investigate this issue, we compared reading behaviour of Northern and Southern English participants who have differing pronunciations for words like 'glass', in which the vowel duration is short in a Northern accent and long in a Southern accent. Participants' eye movements were monitored while they silently read limericks in which the end words of the first two lines (e.g., glass/class would be pronounced differently by Northern and Southern participants. The final word of the limerick (e.g., mass/sparse then either did or did not rhyme, depending on the reader's accent. Results showed disruption to eye movement behaviour when the final word did not rhyme, determined by the reader's accent, suggesting that inner speech resembles our own voice.

    Breen, Mara; Clifton, Charles

    2011-02-01

    This paper presents findings from two eye-tracking studies designed to investigate the role of metrical prosody in silent reading. In Experiment 1, participants read stress-alternating noun-verb or noun-adjective homographs (e.g. PREsent, preSENT) embedded in limericks, such that the lexical stress of the homograph, as determined by context, either matched or mismatched the metrical pattern of the limerick. The results demonstrated a reading cost when readers encountered a mismatch between the predicted and actual stress pattern of the word. Experiment 2 demonstrated a similar cost of a mismatch in stress patterns in a context where the metrical constraint was mediated by lexical category rather than by explicit meter. Both experiments demonstrated that readers are slower to read words when their stress pattern does not conform to expectations. The data from these two eye-tracking experiments provide some of the first on-line evidence that metrical information is part of the default representation of a word during silent reading.

    Full Text Available This study attempted to determine the effect of background music while silent reading on Iranian EFL learners’ reading comprehension. The participants were 57 Iranian EFL learners between the ages of 14 and 16 in two 3rd grade high schoolclasses at pre-intermediate proficiency level. Before treatment,both experimental and control groups took a reading comprehension pretest. In the experimental group, the researchers played Mozart sonatas as background music and asked them to read the passage silently and then answer the reading comprehension questions. In the control group, the procedure was the same, but no music was played while silent reading by the students. After ten sessions, the students of both groups were asked to answer another independent but parallel form of reading section of PET as their post-test. The independent samples t-testresultsindicated that the experimental group outperformed the control group in reading comprehension posttest, and listening to background music while silent reading had a significantly positive effect on Iranian EFL learners’ reading comprehension. The results of the present study have implications for EFL students, teachers, and teacher educators as well as syllabus designers and materials developers.

    Price, Iya Khelm; Witzel, Naoko; Witzel, Jeffrey

    2015-11-01

    This study reports 2 eye-tracking experiments investigating form interference during sentence-level silent reading. The items involved reduced and unreduced relative clauses (RCs) with words that were orthographically and phonologically similar (injection-infection; O+P+, Experiment 1) as well as with words that were orthographically similar, but phonologically dissimilar (laughter-daughter; O+P-, Experiment 2). Both experiments revealed syntactic processing disruptions for reduced RCs. Processing difficulty was also observed at the form-related word in both experiments under first-pass and second-pass reading measures. These form-interference effects did not interact with structural processing difficulty under first-pass measures in either experiment. Under second-pass time, there were larger processing disruptions for reduced RCs in O+P+ sentences relative to their controls. This was not the case, however, for O+P- sentences. These results suggest 2 components to form-interference effects during silent reading: (a) an early, low-level component that is driven in large part by visual form overlap and (b) a component that relates to late stages of interpretation and that is associated more closely with phonological form overlap.

    2016-01-01

    Reading fluency is a critical skill to improve the quality of our daily life and working efficiency. The majority of previous studies focused on oral reading fluency rather than silent reading fluency, which is a much more dominant reading mode that is used in middle and high school and for leisure reading. It is still unclear whether the oral and silent reading fluency involved the same underlying skills. To address this issue, the present study examined the relationship between the visual rapid processing and Chinese reading fluency in different modes. Fifty-eight undergraduate students took part in the experiment. The phantom contour paradigm and the visual 1-back task were adopted to measure the visual rapid temporal and simultaneous processing respectively. These two tasks reflected the temporal and spatial dimensions of visual rapid processing separately. We recorded the temporal threshold in the phantom contour task, as well as reaction time and accuracy in the visual 1-back task. Reading fluency was measured in both single-character and sentence levels. Fluent reading of single characters was assessed with a paper-and-pencil lexical decision task, and a sentence verification task was developed to examine reading fluency on a sentence level. The reading fluency test in each level was conducted twice (i.e., oral reading and silent reading). Reading speed and accuracy were recorded. The correlation analysis showed that the temporal threshold in the phantom contour task did not correlate with the scores of the reading fluency tests. Although, the reaction time in visual 1-back task correlated with the reading speed of both oral and silent reading fluency, the comparison of the correlation coefficients revealed a closer relationship between the visual rapid simultaneous processing and silent reading. Furthermore, the visual rapid simultaneous processing exhibited a significant contribution to reading fluency in silent mode but not in oral reading mode. These

    The present study aimed to define differences between silent and oral reading with respect to spatial and temporal eye movement parameters. Eye movements of 22 German-speaking adolescents (14 females; mean age = 13;6 years;months) were recorded while reading an age-appropriate text silently and orally. Preschool cognitive abilities were assessed at the participants' age of 5;7 (years;months) using the Kaufman Assessment Battery for Children. The participants' reading speed and reading comprehension at the age of 13;6 (years;months) were determined using a standardized inventory to evaluate silent reading skills in German readers (Lesegeschwindigkeits- und -verständnistest für Klassen 6-12). The results show that (i) reading mode significantly influenced both spatial and temporal characteristics of eye movement patterns; (ii) articulation decreased the consistency of intraindividual reading performances with regard to a significant number of eye movement parameters; (iii) reading skills predicted the majority of eye movement parameters during silent reading, but influenced only a restricted number of eye movement parameters when reading orally; (iv) differences with respect to a subset of eye movement parameters increased with reading skills; (v) an overall preschool cognitive performance score predicted reading skills at the age of 13;6 (years;months), but not eye movement patterns during either silent or oral reading. However, we found a few significant correlations between preschool performances on subscales of sequential and simultaneous processing and eye movement parameters for both reading modes. Overall, the findings suggest that eye movement patterns depend on the reading mode. Preschool cognitive abilities were more closely related to eye movement patterns of oral than silent reading, while reading skills predicted eye movement patterns during silent reading, but less so during oral reading.

    To investigate the relationship between silent reading performance and visual field defects in patients with glaucoma using an eye tracking system. Fifty glaucoma patients (Group G; mean age, 52.2 years, standard deviation: 11.4 years) and 20 normal controls (Group N; mean age, 46.9 years; standard deviation: 17.2 years) were included in the study. All participants in Group G had early to advanced glaucomatous visual field defects but better than 20/20 visual acuity in both eyes. Participants silently read Japanese articles written horizontally while the eye tracking system monitored and calculated reading duration per 100 characters, number of fixations per 100 characters, and mean fixation duration, which were compared with mean deviation and visual field index values from Humphrey visual field testing (24-2 and 10-2 Swedish interactive threshold algorithm standard) of the right versus left eye and the better versus worse eye. There was a statistically significant difference between Groups G and N in mean fixation duration (G, 233.4 msec; N, 215.7 msec; P = 0.010). Within Group G, significant correlations were observed between reading duration and 24-2 right mean deviation (rs = -0.280, P = 0.049), 24-2 right visual field index (rs = -0.306, P = 0.030), 24-2 worse visual field index (rs = -0.304, P = 0.032), and 10-2 worse mean deviation (rs = -0.326, P = 0.025). Significant correlations were observed between mean fixation duration and 10-2 left mean deviation (rs = -0.294, P = 0.045) and 10-2 worse mean deviation (rs = -0.306, P = 0.037), respectively. The severity of visual field defects may influence some aspects of reading performance. At least concerning silent reading, the visual field of the worse eye is an essential element of smoothness of reading.

    Full Text Available This study presents the first two ERP reading studies of comma-induced effects of covert (implicit prosody on syntactic parsing decisions in English. The first experiment used a balanced 2 x 2 design in which the presence/absence of commas determined plausibility (e.g., John, said Mary, was the nicest boy at the party versus John said Mary was the nicest boy at the party. The second reading experiment replicated a previous auditory study investigating the role of overt prosodic boundaries in closure ambiguities (Pauker et al., 2011. In both experiments, commas reliably elicited CPS components and generally played a dominant role in determining parsing decisions in the face of input ambiguity. The combined set of findings provides further evidence supporting the claim that mechanisms subserving speech processing play an active role during silent reading.

    In daily life, responses are often facilitated by anticipatory imagery of expected targets which are announced by associated stimuli from different sensory modalities. Silent music reading represents an intriguing case of visuotonal modality transfer in working memory as it induces highly defined auditory imagery on the basis of presented visuospatial information (i.e. musical notes). Using functional MRI and a delayed sequence matching-to-sample paradigm, we compared brain activations during retention intervals (10s) of visual (VV) or tonal (TT) unimodal maintenance versus visuospatial-to-tonal modality transfer (VT) tasks. Visual or tonal sequences were comprised of six elements, white squares or tones, which were low, middle, or high regarding vertical screen position or pitch, respectively (presentation duration: 1.5s). For the cross-modal condition (VT, session 3), the visuospatial elements from condition VV (session 1) were re-defined as low, middle or high "notes" indicating low, middle or high tones from condition TT (session 2), respectively, and subjects had to match tonal sequences (probe) to previously presented note sequences. Tasks alternately had low or high cognitive load. To evaluate possible effects of music reading expertise, 15 singers and 15 non-musicians were included. Scanner task performance was excellent in both groups. Despite identity of applied visuospatial stimuli, visuotonal modality transfer versus visual maintenance (VT>VV) induced "inhibition" of visual brain areas and activation of primary and higher auditory brain areas which exceeded auditory activation elicited by tonal stimulation (VT>TT). This transfer-related visual-to-auditory activation shift occurred in both groups but was more pronounced in experts. Frontoparietal areas were activated by higher cognitive load but not by modality transfer. The auditory brain showed a potential to anticipate expected auditory target stimuli on the basis of non-auditory information and

  7. At-lexical, articulatory interference in silent reading: the "upstream" tongue-twister effect.

    In two experiments, we investigated the interpretation and boundary conditions of the tongue-twister (TT) effect in silent reading. Previously, McCutchen, Bell, France, and Perfetti (1991) observed a TT effect when students made semantic acceptability judgments on sentences, but not when they made lexical decisions on lists of words. Using similar methodology in Experiment 1, along with two changes (using "better" TTs and longer word lists), we observed a TT effect in a lexical decision task. In Experiment 2, a memory span task revealed that students recalled fewer words from TT lists than from control lists. These results suggest that the basic mechanism of the TT effect may be articulatory, rather than working-memory, interference that occurs during lexical access and resurfaces post-lexically, inhibiting efforts to maintain the temporal order of several words.

    Seeing the articulatory gestures of the speaker ("speech reading") enhances speech perception especially in noisy conditions. Recent neuroimaging studies tentatively suggest that speech reading activates speech motor system, which then influences superior-posterior temporal lobe auditory areas via an efference copy. Here, nineteen healthy volunteers were presented with silent videoclips of a person articulating Finnish vowels /a/, /i/ (non-targets), and /o/ (targets) during event-related functional magnetic resonance imaging (fMRI). Speech reading significantly activated visual cortex, posterior fusiform gyrus (pFG), posterior superior temporal gyrus and sulcus (pSTG/S), and the speech motor areas, including premotor cortex, parts of the inferior (IFG) and middle (MFG) frontal gyri extending into frontal polar (FP) structures, somatosensory areas, and supramarginal gyrus (SMG). Structural equation modelling (SEM) of these data suggested that information flows first from extrastriate visual cortex to pFS, and from there, in parallel, to pSTG/S and MFG/FP. From pSTG/S information flow continues to IFG or SMG and eventually somatosensory areas. Feedback connectivity was estimated to run from MFG/FP to IFG, and pSTG/S. The direct functional connection from pFG to MFG/FP and feedback connection from MFG/FP to pSTG/S and IFG support the hypothesis of prefrontal speech motor areas influencing auditory speech processing in pSTG/S via an efference copy.

    Teacher read-alouds (TRA) are common in middle and high school content area classes. Because the practice of reading the textbook out loud to students is often used out of concern about students’ ability to understand and learn from text when reading silently (SR), this randomized controlled trial was designed to experimentally manipulate text reading while blocking on all other instructional elements to determine the relative effects on learning content. Predominantly Spanish–English bilingual twelfth-graders (n = 123) were randomly assigned to either a TRA or SR condition and provided 1 week of high quality instruction in US history. Daily lessons included teaching key terms in the passage, previewing text headings, and conducting comprehension checks. Results of immediate, 1-week delayed, and 1-month delayed assessments of content learning revealed no significant differences between the two groups. Students were also asked to rate the method of reading they believed best helped them understand and remember information. Students in the SR condition more consistently agreed that reading silently was beneficial. Findings suggest low performing adolescents of different linguistic backgrounds can learn content as well when reading appropriately challenging text silently as when the teacher reads the text aloud to them.

    The purpose of this study was to investigate the relations among oral and silent reading fluency and reading comprehension for students in Grades 6 to 8 (n = 1,421) and the use of fluency scores to identify middle school students who are at risk for failure on a high-stakes reading test. Results indicated moderate positive relations between measures of fluency and comprehension. Oral reading fluency (ORF) on passages was more strongly related to reading comprehension than ORF on word lists. A group-administered silent reading sentence verification test approximated the classification accuracy of individually administered ORF passages. The correlation between a maze task and comprehension was weaker than has been reported for elementary students. The best predictor of a high-stakes reading comprehension test was the previous year’s administration of the grade-appropriate test; fluency and verbal knowledge measures accounted for only small amounts of unique variance beyond that accounted for by the previous year’s administration.

    Gunshot tracheal injuries represent life-threatening events and usually necessitate emergent surgical intervention. We report a case of an exceptional finding of a patient with retained ballistic fragments in the soft tissues of the thorax, proximal to the right subclavian artery and the trachea, carrying silently his wounds for two decades without any medical or surgical intervention. The bullet pellet on the upper part of the trachea seen accidentally in the chest computed tomography, was also found during bronchoscopy. In short "luck's always to blame".

    Poliovirus vaccine coverage in Israel is over 90%. The last nine birth cohorts have been vaccinated exclusively with inactivated polio vaccine (IPV). However, between February and July 2013 type 1 wild poliovirus (WPV1) was detected persistently in 10 and intermittently in 8 of 47 environmental surveillance sites in southern and central Israel and in 30 stool samples collected during July from healthy individuals in southern Israel. We report results of sequence and phylogenetic analyses of genes encoding capsid proteins to determine the source and transmission mode of the virus. WPV1 capsid protein 1 nucleotide sequences were most closely related to South Asia (SOAS) cluster R3A polioviruses circulating in Pakistan in 2012 and isolated from Egyptian sewage in December 2012. There was no noticeable geographical clustering within WPV1-positive sites. Uniform codon usage among isolates from Pakistan, Egypt and Israel showed no signs of optimisation or deoptimisation. Bayesian phylogenetic time clock analysis of the entire capsid coding region (2,643 nt) with a 1.1% evolutionary rate indicated that Israeli and Egyptian WPV1-SOAS lineages diverged in September 2012, while Israeli isolates split into two sub-branches after January 2013. This suggests one or more introduction events into Israel with subsequent silent circulation despite high population immunity.

    To evaluate the impact of age-related macular degeneration (AMD) on short out-loud and sustained silent reading speeds, and reading comprehension. Prospective, cross-sectional. Setting: Wilmer Eye Institute. Literate, native-English speakers with and without AMD. AMD participants had better-eye visual acuity (VA) 20/100, while controls had binocular VA >20/32. MNRead was used to assess short-duration out-loud reading speed. Sustained silent reading test was used to evaluate sustained silent reading speeds, while reading comprehension was assessed based on silent reading test text. MNRead maximum reading speed, sustained-silent reading speed, and comprehension score. Analyses included 24 AMD patients and 22 controls. In age-adjusted regressions, AMD participants, compared to controls, read 46 words per minute (wpm) slower on MNRead (95% confidence interval [CI]: -66, -26, P reading speeds between groups (β = 0.99, 95% CI: -41.8, 43.8, P = .96). In other models, there was a decrement of 12.6 wpm on MNRead per 0.1 worsening logMAR (95% CI: -18.7, -6.6, P reading speed (β = -10.1, 95% CI: -22.4, 2.1, P = .10). However, AMD participants had substantially lower comprehension scores than controls (53% vs 85% correct, P read slower than controls when forced to read out loud. When asked to read silently over a longer duration, both groups read at similar speeds, though AMD patients demonstrated substantially lower comprehension scores, suggesting that they chose to sacrifice comprehension for speed.

    2008-09-01

    Eye movement research of reading has been done on a battery of eye-tracking setups during last decades. We compared reading data of the same group of six students, their eyes were tracked by a video-based helmet-mounted system with the data sampling frequency of 50 Hz and a setup with a chin-rest at 240 Hz. We found that not only the number of fixations may decrease after reading practice, but so does also the mean duration of fixations. In spite of the short duration of saccades, their distributions and changes in them are similarly reported in the two experimental conditions. Lack of significant correlation in the HED data testifies to the result variability due to measurement technique. We conclude that the head-free setup is applicable in reading research but has insufficient precision to track changes in reading patterns.

    We know that from mid-childhood onwards most new words are learned implicitly via reading; however, most word learning studies have taught novel items explicitly. We examined incidental word learning during reading by focusing on the well-documented finding that words which are acquired early in life are processed more quickly than those acquired later. Novel words were embedded in meaningful sentences and were presented to adult readers early (day 1) or later (day 2) during a five-day exposure phase. At test adults read the novel words in semantically neutral sentences. Participants' eye movements were monitored throughout exposure and test. Adults also completed a surprise memory test in which they had to match each novel word with its definition. Results showed a decrease in reading times for all novel words over exposure, and significantly shorter [corrected] total reading times at test for early than late novel words. Early-presented novel words were also remembered better in the offline test. Our results show that order of presentation influences processing time early in the course of acquiring a new word, consistent with partial and incremental growth in knowledge occurring as a function of an individual's experience with each word.

  6. Special report: silent disasters.

    Eriksson, Anneli

    2007-12-01

    Disasters occur not only in war and conflict or after natural events, such as earthquakes or floods. In fact, the death of hundreds of thousands of children in Niger every year, often for treatable conditions, could just as well qualify as a disaster situation. A lack of funding for health care and health-care staff and user fee policies for health care in very poor or unstable settings challenge international agreements that make statements about the right to health and access to health care for all people. This paper argues that although sustainable development is important, today many are without essential health care and die in the silent disasters of hunger and poverty. In other words, the development of health care appears to be stalled for the sake of sustainability.

  14. A Silent Safety Program

    Science.gov (United States)

    Goodin, James Ronald

    2006-01-01

    NASA's Columbia Accident Investigation Board (CAIB) referred 8 times to the NASA "Silent Safety Program." This term, "Silent Safety Program" was not an original observation but first appeared in the Rogers Commission's Investigation of the Challenger Mishap. The CAIB on page 183 of its report in the paragraph titled 'Encouraging Minority Opinion,' stated "The Naval Reactor Program encourages minority opinions and "bad news." Leaders continually emphasize that when no minority opinions are present, the responsibility for a thorough and critical examination falls to management. . . Board interviews revealed that it is difficult for minority and dissenting opinions to percolate up through the agency's hierarchy. . ." The first question and perhaps the only question is - what is a silent safety program? Well, a silent safety program may be the same as the dog that didn't bark in Sherlock Holmes' "Adventure of the Silver Blaze" because system safety should behave as a devil's advocate for the program barking on every occasion to insure a critical review inclusion. This paper evaluates the NASA safety program and provides suggestions to prevent the recurrence of the silent safety program alluded to in the Challenger Mishap Investigation. Specifically targeted in the CAM report, "The checks and balances the safety system was meant to provide were not working." A silent system safety program is not unique to NASA but could emerge in any and every organization. Principles developed by Irving Janis in his book, Groupthink, listed criteria used to evaluate an organization's cultural attributes that allows a silent safety program to evolve. If evidence validates Jams's criteria, then Jams's recommendations for preventing groupthink can also be used to improve a critical evaluation and thus prevent the development of a silent safety program.

    From a developmental framework, relations among list reading fluency, oral and silent reading fluency, listening comprehension, and reading comprehension might be expected to change as children’s reading skills develop. We examined developmental relations among these constructs in a latent-variable longitudinal study of first- and second-grade students. Results showed that list reading fluency was uniquely related to reading comprehension in grade one, but not in grade two after accounting for text reading fluency (oral or silent) and listening comprehension. In contrast, text reading fluency was uniquely related to reading comprehension in grade two, but not in grade one, after accounting for list reading fluency and listening comprehension. When oral and silent reading fluency were compared, oral reading fluency was uniquely related to reading comprehension after accounting for silent reading fluency in grade one whereas in grade two, silent reading fluency was uniquely related to reading comprehension after accounting for oral reading fluency.

Each type of test was conducted in a different day, always in the afternoon. No significant statistical difference has been noticed between the initial and final intraocular pressure mean in the different groups, when reading, performing exercises or exercises combined with reading. To read and to work out--either separately or jointly--does not pose an aggravating factor to the intraocular pressure of patients with primary open glaucoma or ocular hypertension, using prostaglandin, prostamide or beta-blocker analogues.

    Difficulties in reading comprehension are common in children and adolescents with Attention Deficit/Hyperactivity Disorder (ADHD). The current study aimed at investigating the relation between sustained attention and reading comprehension among adolescents with and without ADHD. Another goal was to examine the impact of two manipulations of the text on the efficiency of reading comprehension: Spacing (standard- vs. double-spacing) and Type of presentation (computer screen vs. hard copy). Reading comprehension of two groups of adolescents (participants with ADHD and normal controls) was assessed and compared in four different conditions (standard printed, spaced printed, standard on computer screen, spaced on computer screen). In addition, participants completed a visual sustained attention task. Significant differences in reading comprehension and in sustained attention were obtained between the two groups. Also, a significant correlation was obtained between sustained attention and reading comprehension. Moreover, a significant interaction was revealed between presentation-type, spacing and level of sustained attention on reading comprehension. Implications for reading intervention and the importance of early assessment of attention functioning are discussed. Copyright © 2012 Elsevier Ltd. All rights reserved.

  1. Arsenic: The Silent Killer

    Energy Technology Data Exchange (ETDEWEB)

    Foster, Andrea (USGS)

    2006-02-28

    Andrea Foster uses x-rays to determine the forms of potentially toxic elements in environmentally-important matrices such as water, sediments, plants, and microorganisms. In this free public lecture, Foster will discuss her research on arsenic, which is called the silent killer because dissolved in water, it is colorless, odorless, and tasteless, yet consumption of relatively small doses of this element in its most toxic forms can cause rapid and violent death. Arsenic is a well-known poison, and has been used as such since ancient times. Less well known is the fact that much lower doses of the element, consumed over years, can lead to a variety of skin and internal cancers that can also be fatal. Currently, what has been called the largest mass poisoning in history is occurring in Bangladesh, where most people are by necessity drinking ground water that is contaminated with arsenic far in excess of the maximum amounts determined to be safe by the World Health Organization. This presentation will review the long and complicated history with arsenic, describe how x-rays have helped explain the high yet spatially variable arsenic concentrations in Bangladesh, discuss the ways in which land use in Bangladesh may be exacerbating the problem, and summarize the impact of this silent killer on drinking water systems worldwide.

    Coronary stent infections in general and stent abscesses (SAs) in particular are rare but often deadly complications. Most SAs manifest with fever and chest pain within 30 days after intervention and require antibiotics and stent removal. A 45-year-old man with second ST elevated myocardial infarction and cardiogenic shock was admitted to a hospital that had no cardiac catheterization laboratory. The patient underwent fibrinolytic therapy with alteplase but died 1 h later. His medical history revealed posterior myocardial infarction 7 years before, which had been successfully treated with a bare metal stent of the right coronary artery. The post-discharge observation had been unremarkable with no evidence of ischaemia or infection but gross non-compliance. Autopsy revealed complete closure of the left main coronary artery and a surprise additional finding, namely SA; the stented portion of the artery was enveloped by an abscess, and purulent material completely occluded the stent, which was floating in pus. Impressions: Since coronary angioplasty is so common, the incidence of late silent SA is probably higher than expected, especially considering that there is often a lack of clinical manifestations. Clinicians should be cognizant of this complication. More attention may be required to assess the condition of existing stents during repeated interventions. Gross non-compliance and/or early withdrawal from dual anti-platelet therapy may be directly responsible for the development of silent delayed SA.

    To evaluate the impact of dry eye on reading performance. Out-loud and silent reading in patients with clinically significant dry eye (n=41) and controls (n=50) was evaluated using standardised texts. Dry eye measures included tear film break-up time, Schirmer's test and corneal epithelial staining. Symptoms were assessed by the Ocular Surface Disease Index (OSDI). The dry eye group had a greater proportion of women as compared with the control group but did not differ in age, race, education level or visual acuity (p≥0.05 for all). Out-loud reading speed averaged 148 words per minute (wpm) in dry eye subjects and 163 wpm in controls (p=0.006). Prolonged silent reading speed averaged 199 wpm in dry eye subjects versus 226 wpm in controls (p=0.03). In multivariable regression models, out-loud and sustained silent reading speeds were 10 wpm (95% CI -20 to -1 wpm, p=0.039) and 14% (95% CI -25% to -2%, p=0.032) slower, respectively, in dry eye subjects as compared with controls. Greater corneal staining was associated with slower out-loud (-2 wpm/1 unit increase in staining score, 95% CI =-3 to -0.3 wpm) and silent (-2%, 95% CI -4 to -0.6 wpm) reading speeds (preading speed (preading speeds, providing direct evidence regarding the functional impact of dry eye.

    To determine if the ability to divide attention affects the relationship between glaucoma-related vision loss and reading speed. Better eye mean deviation (MD), contrast sensitivity (CS), and better-eye distance visual acuity (VA) were measured in 28 participants with glaucoma and 21 controls. Reading speeds were assessed using MNRead, IRest, and sustained silent reading tests (words per minute, wpm). The ability to divide attention was measured using the Brief Test of Attention (BTA; scored 0-10). Multivariable linear regression models were used to determine the relationship between visual factors and reading speeds. Effect modification by BTA score (low BTA: reading speed on MNRead test for participants with low BTA scores (β = -9 wpm; 95% confidence interval [CI]: -16, -2), but not for those with high BTA scores (β = -2 wpm; 95% CI: -6, +2). Similarly, for the IRest test, worse CS was associated with slower reading speeds (β = -12 wpm; 95% CI: -20, -4) among those with low, but not high BTA scores (β = -4 wpm; 95% CI: -10, +2). For the sustained silent reading test, glaucoma status (versus controls), worse visual field (VF) MD (per 5 dB), and worse CS were associated with 39%, 21%, and 19% slower reading speeds, respectively, for those with low BTA scores (P 0.1 for all). Decreased ability to divide attention, indicated by lower BTA scores, is associated with slower reading speeds in glaucoma with reduced CS and VF defects.

  8. Subclinical hyperfunctioning pituitary adenomas: The silent tumors

    Science.gov (United States)

    Cooper, Odelia; Melmed, Shlomo

    2012-01-01

    Pituitary adenomas are classified by function as defined by clinical symptoms and signs of hormone hypersecretion with subsequent confirmation on immunohistochemical staining. However, positive immunostaining for pituitary cell types has been shown for clinically nonfunctioning adenomas, and this entity is classified as silent functioning adenoma. Most common in these subtypes include silent gonadotroph adenomas, silent corticotroph adenomas and silent somatotroph adenomas. Less commonly, silent prolactinomas and thyrotrophinomas are encountered. Appropriate classification of these adenomas may affect follow-up care after surgical resection. Some silent adenomas such as silent corticotroph adenomas follow a more aggressive course, necessitating closer surveillance. Furthermore, knowledge of the immunostaining characteristics of silent adenomas may determine postoperative medical therapy. This article reviews the incidence, clinical behavior, and pathologic features of clinically silent pituitary adenomas. PMID:22863387

    Six cases of silent thyroiditis are described. Clinical, analytical, therapeutical and prognostical features are reviewed. Descriptive and retrospective study. Outpatient endocrinological clinic of a General Hospital Six women (age 26-41 years) that fulfil clinical and analytical criteria of silent thyroiditis. In 4 patients thyroiditis was diagnosed in the postpartum period and in the remaining 2 there was no relationship with pregnancy. Serum levels of thyroid hormones and thyroglobulin and thyroid peroxidase antibodies were measured in all patients. Follow-up period was between 12 and 41 months. The 2 patients with the sporadic form of silent thyroiditis showed clinical and analytical data of thyrotoxicosis that spontaneously resolved. The remaining 4 patients presented with hypothyroidism. In one of them the hypothyroidism spontaneously resolved, in 2 it became permanent and in a further one it developed to subclinical hypothyroidism. Silent thyroiditis (sporadic or postpartum) is a frequent disorder, usually benign and transient. It can present in different clinic forms and evolve to resolution of permanent thyroid dysfunction.

    Özçalışkan, Şeyda; Lucero, Ché; Goldin-Meadow, Susan

    2016-03-01

    Languages differ in how they organize events, particularly in the types of semantic elements they express and the arrangement of those elements within a sentence. Here we ask whether these cross-linguistic differences have an impact on how events are represented nonverbally; more specifically, on how events are represented in gestures produced without speech (silent gesture), compared to gestures produced with speech (co-speech gesture). We observed speech and gesture in 40 adult native speakers of English and Turkish (N=20/per language) asked to describe physical motion events (e.g., running down a path)-a domain known to elicit distinct patterns of speech and co-speech gesture in English- and Turkish-speakers. Replicating previous work (Kita & Özyürek, 2003), we found an effect of language on gesture when it was produced with speech-co-speech gestures produced by English-speakers differed from co-speech gestures produced by Turkish-speakers. However, we found no effect of language on gesture when it was produced on its own-silent gestures produced by English-speakers were identical in how motion elements were packaged and ordered to silent gestures produced by Turkish-speakers. The findings provide evidence for a natural semantic organization that humans impose on motion events when they convey those events without language. Copyright © 2015 Elsevier B.V.

    2016-01-01

    Auditory perceptual simulation (APS) during silent reading refers to situations in which the reader actively simulates the voice of a character or other person depicted in a text. In three eye-tracking experiments, APS effects were investigated as people read utterances attributed to a native English speaker, a non-native English speaker, or no speaker at all. APS effects were measured via online eye movements and offline comprehension probes. Results demonstrated that inducing APS during silent reading resulted in observable differences in reading speed when readers simulated the speech of faster compared to slower speakers and compared to silent reading without APS. Social attitude survey results indicated that readers' attitudes towards the native and non-native speech did not consistently influence APS-related effects. APS of both native speech and non-native speech increased reading speed, facilitated deeper, less good-enough sentence processing, and improved comprehension compared to normal silent reading.

Identificou aumento sistemático na competência de leitura de 1ª a 5ª séries, além de aumentos assistemáticos até a 1ª série do ensino médio, e comparou padrões de erros nos subtestes. Resultados revelaram dissociações duplas entre leitores surdos e ouvintes quanto ao padrão de erros nos subtestes: enquanto ouvintes se deixam enganar mais pela semelhança fonológica, surdos se deixam enganar mais pela visual. Enquanto ouvintes privilegiam a forma ortográfica em detrimento da correção semântica, surdos fazem o oposto. Devido à dificuldade de surdos em fazer conferência perilexical, sua leitura mostrou-se dependente de mecanismos visuais diretos de reconhecimento e acesso ao significado.

Results revealed double dissociation between deaf and hearing readers regarding error patterns across subtests: Hearing readers tended to be fooled more by phonological similarity than by visual similarity, whereas the opposite was found with deaf readers. Also, the hearing readers relied more on orthographic form than on semantic adequacy, whereas deaf readers did the opposite. Therefore, deaf reading was shown to depend essentially upon visual direct word recognition and semantic access mechanisms due to poor efficacy of perilexical checking mechanisms. Word Reading Competence Test was

    Full Text Available For decades, embalmed cadavers have played an important role in teaching anatomy to the scientists and doctors of the future. Most anatomy departments use a traditional formaldehyde-based embalming method, but formalin embalming makes the bodies very rigid, which limits their usefulness for procedures other than dissection. A more recent embalming method developed by W. Thiel has allowed these "silent teachers" to take on a further role in applied anatomy research and teaching: to act as models for surgical training and medical research.

    The prevalence of clinically silent corticotroph macroadenomas is unknown. Our aim was to determine the prevalence of clinically silent corticotroph macroadenomas among all pituitary macroadenomas. Patients scheduled to have transsphenoidal surgery for any sellar mass were prospectively evaluated clinically and biochemically. Adults who were scheduled for transsphenoidal surgery for a sellar mass at a single academic medical centre. Patients were assessed clinically prior to surgery and graded as having typical, mild or no Cushingoid features. They were assessed biochemically by plasma ACTH and 24-h urine free cortisol (UFC). Excised tissue was examined histologically, and pituitary macroadenomas, examined by immunohistochemistry. Patients with corticotroph macroadenomas were classified as clinically silent if they exhibited no Cushingoid features but had elevated plasma ACTH and/or 24-h UFC. They were classified as totally silent if they exhibited neither Cushingoid features nor elevated plasma ACTH or 24-h UFC. Of 124 patients who had pathologically confirmed pituitary macroadenomas, 20 (16%) had corticotroph macroadenomas. Eight (40%) of these were clinically silent, in that they had no Cushingoid features but could be identified biochemically by elevated plasma ACTH (seven) and/or 24-h UFC (three). Five (25%) were totally silent. A substantial minority (16%) of pituitary macroadenomas treated surgically are corticotroph adenomas. Of these, 40% are clinically silent but can be recognized by elevated plasma ACTH and/or 24-h UFC. Recognizing these adenomas may influence the surgical approach and provide a marker by which to follow the response to treatment. © 2016 John Wiley & Sons Ltd.

    2008-07-01

    Poetic devices like alliteration can heighten readers' aesthetic experiences and enhance poets' recall of their epic pieces. The effects of such devices on memory for and appreciation of poetry are well known; however, the mechanisms underlying these effects are not yet understood. We used current theories of language comprehension as a framework for understanding how alliteration affects comprehension processes. Across three experiments, alliterative cues reactivated readers' memories for previous information when it was phonologically similar to the cue. These effects were obtained when participants read aloud and when they read silently, and with poetry and prose. The results support everyday intuitions about the effects of poetry and aesthetics, and explain the nature of such effects. These findings extend the scope of general memory models by indicating their capacity to explain the influence of nonsemantic discourse features.

  11. Silent myocardial ischemia during coronary angioplasty.

    Dellborg, M; Emanuelsson, H; Swedberg, K

    1993-01-01

    Silent myocardial ischemia is a marker in patients with coronary artery disease identifying those at high risk for subsequent cardiac events. During provoked myocardial ischemia some patients with angina pectoris do not develop chest pain. Are there clinical, angiographic or electrocardiographic differences between patients with chest pain as compared with patients without chest pain during provoked myocardial ischemia? Coronary angioplasty is a well-established method for the treatment of coronary stenosis, but it is also an interesting model for the study of myocardial ischemia as a result of coronary occlusion. We monitored 114 patients with angina pectoris during coronary angioplasty with dynamic, computerized vectorcardiography. During inflation of the balloon 33 of 114 patients had silent ischemia. Patients with silent myocardial ischemia had similar reasons for terminating the preangioplasty exercise test and where on similar anti-ischemic drug regimes. Silent myocardial ischemia was significantly associated with a history of diabetes, presence of collaterals, a history of less severe previous angina and less ST segment changes during angioplasty as compared with patients with painful ischemia. It is suggested that during coronary angioplasty silent ischemia may be caused by a less severe degree of ischemia, possibly as a result of the protective effect of collaterals.

  15. Mind-wandering in younger and older adults: converging evidence from the Sustained Attention to Response Task and reading for comprehension.

    Science.gov (United States)

    Jackson, Jonathan D; Balota, David A

    2012-03-01

    One mechanism that has been hypothesized to contribute to older adults' changes in cognitive performance is goal neglect or impairment in maintaining task set across time. Mind-wandering and task-unrelated thought may underlie these potential age-related changes. The present study investigated age-related changes in mind-wandering in three different versions of the Sustained Attention to Response Task (SART), along with self-reported mind-wandering during a reading for comprehension task. In the SART, both younger and older adults produced similar levels of faster reaction times before No-Go errors of commission, whereas, older adults produced disproportionate post-error slowing. Subjective self-reports of mind-wandering recorded during the SART and the reading task indicated that older adults were less likely to report mind-wandering than younger adults. Discussion focuses on cognitive and motivational mechanisms that may account for older adults' relatively low levels of reported mind-wandering.

  17. Relativistic numerical cosmology with silent universes

    Science.gov (United States)

    Bolejko, Krzysztof

    2018-01-01

    Relativistic numerical cosmology is most often based either on the exact solutions of the Einstein equations, or perturbation theory, or weak-field limit, or the BSSN formalism. The silent universe provides an alternative approach to investigate relativistic evolution of cosmological systems. The silent universe is based on the solution of the Einstein equations in 1  +  3 comoving coordinates with additional constraints imposed. These constraints include: the gravitational field is sourced by dust and cosmological constant only, both rotation and magnetic part of the Weyl tensor vanish, and the shear is diagnosable. This paper describes the code simsilun (free software distributed under the terms of the reposi General Public License), which implements the equations of the silent universe. The paper also discusses applications of the silent universe and it uses the Millennium simulation to set up the initial conditions for the code simsilun. The simulation obtained this way consists of 16 777 216 worldlines, which are evolved from z  =  80 to z  =  0. Initially, the mean evolution (averaged over the whole domain) follows the evolution of the background ΛCDM model. However, once the evolution of cosmic structures becomes nonlinear, the spatial curvature evolves from ΩK =0 to ΩK ≈ 0.1 at the present day. The emergence of the spatial curvature is associated with ΩM and Ω_Λ being smaller by approximately 0.05 compared to the ΛCDM.

  1. (Hardly anyone listening? Writing silent geography

    Directory of Open Access Journals (Sweden)

    Bill Boyd

    2013-10-01

    Full Text Available In 1984, J. Douglas Porteous challenged the geography world to silence. True geographical appreciation cannot be expressed in prose; the logical conclusion is for geographers to be silent. Given that they cannot be silent, Porteous advocated nontraditional writing, such as poetry. In 1994, Paul Cloke illustrated the power of reflective narrative for a geographer grappling to understand the world. In 1998, I started writing geographic poetry. In 2012, I draw these strands together in this reflective essay, drawing on a poetic journey over a decade old now. Can I reflect a sense of place or place-making that transcends traditional geographical expression? Did Porteous truly open a geographic window otherwise closed to me? I conclude the poetry does create geographical sense and sensibility, but more as constructed possibilities than as objective realities. The poetry provides glimpses into the experiences of geographical displacement encountered by many New Australians, and thus may best be considered as metageographical expressions.

    DEFF Research Database (Denmark)

    Wallot, Sebastian; O'Brien, Beth; Haussmann, Anna

    2014-01-01

    Reading speed is commonly used as an index of reading fluency. However, reading speed is not a consistent predictor of text comprehension, when speed and comprehension are measured on the same text within the same reader. This might be due to the somewhat ambiguous nature of reading speed, which...... is sometimes regarded as a feature of the reading process, and sometimes as a product of that process. We argue that both reading speed and comprehension should be seen as the result of the reading process, and that the process of fluent text reading can instead be described by complexity metrics that quantify...... aspects of the stability of the reading process. In this article, we introduce complexity metrics in the context of reading and apply them to data from a self-paced reading study. In this study, children and adults read a text silently or aloud and answered comprehension questions after reading. Our...

    Science.gov (United States)

    Özçalışkan, Şeyda; Lucero, Ché; Goldin-Meadow, Susan

    2016-01-01

    Languages differ in how they organize events, particularly in the types of semantic elements they express and the arrangement of those elements within a sentence. Here we ask whether these cross-linguistic differences have an impact on how events are represented nonverbally; more specifically, on how events are represented in gestures produced without speech (silent gesture), compared to gestures produced with speech (co-speech gesture). We observed speech and gesture in 40 adult native speakers of English and Turkish (N = 20/per language) asked to describe physical motion events (e.g., running down a path)—a domain known to elicit distinct patterns of speech and co-speech gesture in English- and Turkish-speakers. Replicating previous work (Kita & Özyürek, 2003), we found an effect of language on gesture when it was produced with speech—co-speech gestures produced by English-speakers differed from co-speech gestures produced by Turkish-speakers. However, we found no effect of language on gesture when it was produced on its own—silent gestures produced by English-speakers were identical in how motion elements were packaged and ordered to silent gestures produced by Turkish-speakers. The findings provide evidence for a natural semantic organization that humans impose on motion events when they convey those events without language. PMID:26707427

  9. Repeated readings using audiotaped material enhances oral reading in children with reading difficulties.

    Conte, R; Humphreys, R

    1989-02-01

    The method of repeated readings using audiotaped material was implemented in the present study by having poor readers aged 9-13 years listen to and read audiotaped stories until the passages could be read fluently without the tape. A same-age control group with similar reading difficulties was given an alternative reading program that was similar to that received by the experimental group (with respect to creative writing, spelling, phonics, and vocabulary development), but which differed in terms of passage reading exercises (controls read from basal readers, whereas the experimental group did repeated readings of audiotaped material). Only students in the repeated readings of audiotaped material group showed a significant effect of treatment on oral reading, whereas controls showed significantly larger gains in word attack skills. There were no between-group differences in silent reading, a close comprehension test, or isolated word recognition. The pattern of findings suggested that repeated readings of audiotaped material enhances oral reading ability of students with reading difficulties, but the effects of treatment do not generalize to a wide range of reading measures.

    2016-01-01

    Full Text Available Silent sinus syndrome (SSS is a rare entity that is associated with spontaneous, painless, unilateral enophthalmos and hypoglobus resulting from downward bowing of the orbital floor in the absence of any symptomatic sinonasal disease. The diagnosis is suspected clinically, but it is confirmed radiologically by its characteristic imaging features that include maxillary sinus outlet obstruction, sinus opacification and sinus volume loss caused by inward retraction of the sinus walls. The purpose of this article is to acquaint the reader with the clinical and imaging features of the SSS, along with a brief discussion about its pathogenesis and treatment, which is relatively unknown among oral and maxillofacial radiologists.

    2009-12-01

    Functional magnetic resonance imaging was used to measure neural activations in subjects instructed to silently read novels at ordinary and rapid speeds. Among the 19 subjects, 8 were experts in a rapid reading technique. Subjects pressed a button to turn pages during reading, and the interval between turning pages was recorded to evaluate the reading speed. For each subject, we evaluated activations in 14 areas and at 2 instructed reading speeds. Neural activations decreased with increasing reading speed in the left middle and posterior superior temporal area, left inferior frontal area, left precentral area, and the anterior temporal areas of both hemispheres, which have been reported to be active for linguistic processes, while neural activation increased with increasing reading speed in the right intraparietal sulcus, which is considered to reflect visuo-spatial processes. Despite the considerable reading speed differences, correlation analysis showed no significant difference in activation dependence on reading speed with respect to the subject groups and instructed reading speeds. The activation reduction with speed increase in language-related areas was opposite to the previous reports for low reading speeds. The present results suggest that subjects reduced linguistic processes with reading speed increase from ordinary to rapid speed.

    This paper reports the results of two studies focusing on internalization of newly learned items. In study 1, internalization was not confirmed, but reading and memory retention abilities of the reading-aloud subgroup (i.e., students with lower reading proficiency) improved significantly more than the reading-silently subgroup. In study 2 the same effects were confirmed in the reading-aloud subgroup, and internalization of newly learned items was finally confirmed in the reading-aloud group.

    Reading speed is commonly used as an index of reading fluency. However, reading speed is not a consistent predictor of text comprehension, when speed and comprehension are measured on the same text within the same reader. This might be due to the somewhat ambiguous nature of reading speed, which is sometimes regarded as a feature of the reading process, and sometimes as a product of that process. We argue that both reading speed and comprehension should be seen as the result of the reading process, and that the process of fluent text reading can instead be described by complexity metrics that quantify aspects of the stability of the reading process. In this article, we introduce complexity metrics in the context of reading and apply them to data from a self-paced reading study. In this study, children and adults read a text silently or aloud and answered comprehension questions after reading. Our results show that recurrence metrics that quantify the degree of temporal structure in reading times yield better prediction of text comprehension compared to reading speed. However, the results for fractal metrics are less clear. Furthermore, prediction of text comprehension is generally strongest and most consistent across silent and oral reading when comprehension scores are normalized by reading speed. Analyses of word length and word frequency indicate that the observed complexity in reading times is not a simple function of the lexical properties of the text, suggesting that text reading might work differently compared to reading of isolated word or sentences.

    文章を黙読した場合と音読した場合とでは,文章の記憶及び読解の成績にどのような違いが生じるかという問題を,大学生を被験者として検討した。その結果,音読することは,文章を逐語的に記憶する場合には有効であるが,その効果は一時的であることがわかった。これに対し,黙読することは,文章を逐語的に記憶するというよりも,文章の内容を体制化して記憶する場合に有効であり,その効果は音読の場合よりも永続的であることがわかった。 一方,黙読するか音読するかということによって,読解の成績には顕著な差はみられなかった。このことは,黙読するか音読するかという事が読解と無関係であるというより,読解テストのやり方自体に方法上の改善をほどこす必要があるということを示唆するものと考えられる。...

  1. Silent ischemia and severity of pain in acute myocardial infarction

    DEFF Research Database (Denmark)

    Nielsen, F E; Nielsen, S L; Knudsen, F

    1991-01-01

    An overall low tendency to complain of pain, due to a low perception of pain, has been suggested in the pathogenesis of silent ischemia, independent of the extent of the diseased coronaries and a history of previous acute myocardial infarction. This hypothesis has been tested indirectly...... in this retrospective study by comparison of the use of analgesics during admission for a first acute myocardial infarction with the occurrence of silent ischemia at exertion tests four weeks after discharge from hospital. The study did not show a lower use of analgesics in patients with silent ischemia, but this may...

    It has been suggested that the cerebellum is involved in reading acquisition and in particular in the progression from automatic grapheme-phoneme conversion to the internalization of speech required for silent reading. This idea is in line with clinical and neuroimaging data showing a cerebellar role in subvocal rehearsal for printed verbalizable material and with computational "internal models" of the cerebellum suggesting its role in inner speech (i.e. covert speech without mouthing the words). However, studies examining a possible cerebellar role in the suppression of articulatory movements during silent reading acquisition in children are lacking. Here, we report clinical evidence that the cerebellum plays a part in this transition. Reading performances were compared between a group of 17 paediatric patients treated for benign cerebellar tumours and a group of controls matched for age, gender, and parental socio-educational level. The patients scored significantly lower on all reading, but the most striking difference concerned silent reading, perfectly acquired by almost all controls, contrasting with 41 % of the patients who were unable to read any item silently. Silent reading was correlated with the Working Memory Index. The present findings converge with previous reports on an implication of the cerebellum in inner speech and in the automatization of reading. This cerebellar implication is probably not specific to reading, as it also seems to affect non-reading tasks such as counting.

    Silent pituitary adenomas were compared with hormonally active tumors taking into account the size, number, and ultrastructural characteristics of secretory granules (SG). The study group (a total of 79 primary pituitary adenomas) comprised 27 silent, 21 growth hormone (GH)-producing-, 16 prolactin...... approximately 10 to 50% of the granules in each cell. These granules were not seen in hormonally active tumors and considered therefore diagnostic of silent pituitary adenomas....... (PRL)-producing-, 5 GH-PRL-producing- and 10 adrenocorticotropic hormone (ACTH)-producing adenomas. The SG of silent adenomas were significantly smaller than SG in endocrine active adenomas. All hormonally inactive tumors also contained small (mean, 94 nm) specific cytoplasmic granules, designated...

    2008-01-01

    A risk assessment of the Silent Aircraft Initiative's SAX-40 concept design for extremely low noise has been performed. A NASA team developed a list of 27 risk items, and evaluated the level of risk for each item in terms of the likelihood that the risk would occur and the consequences of the occurrence. The following risk items were identified as high risk, meaning that the combination of likelihood and consequence put them into the top one-fourth of the risk matrix: structures and weight prediction; boundary-layer ingestion (BLI) and inlet design; variable-area exhaust and thrust vectoring; displaced-threshold and continuous descent approach (CDA) operational concepts; cost; human factors; and overall noise performance. Several advanced-technology baseline concepts were created to serve as a basis for comparison to the SAX-40 concept. These comparisons indicate that the SAX-40 would have significantly greater research, development, test, and engineering (RDT&E) and production costs than a conventional aircraft with similar technology levels. Therefore, the cost of obtaining the extremely low noise capability that has been estimated for the SAX-40 is significant. The SAX-40 concept design proved successful in focusing attention toward low noise technologies and in raising public awareness of the issue.

  5. Oral malignant melanoma: A silent killer?

    Science.gov (United States)

    Padhye, Ashvini; D’souza, Jovita

    2011-01-01

    Oral malignant melanomas are extremely rare lesions and occur commonly in the maxillary gingiva more frequently on the palate with fewer incidences in the mandibular gingiva. Though these lesions are biologically aggressive, they often go unnoticed since they are clinically asymptomatic in the early stages and usually present merely as a hyperpigmented patch on the gingival surface. These lesions if diagnosed at an early in situ stage are potentially curable and definitely have a better prognosis, but unfortunately as they are clinically asymptomatic, it results in delayed diagnosis thus making the prognosis extremely poor. This paper presents the case of a patient who visited our department with the complaint of darkened patches on the gums and his concern was purely aesthetic. There were no symptoms associated with the hyperpigmented lesions and hence the patient did not approach us earlier. When the lesions grew larger and were unsightly, the patient has seeked dental advice. Histopathologic investigation confirmed the diagnosis as ‘Oral Malignant Melanoma’. Though aggressive therapy was instilled immediately, unfortunately, the patient succumbed to death within a few months after diagnosis as the lesion was highly invasive. Due to the biologically aggressive but clinically silent nature of progression of the lesion, the importance of maintaining a high index of suspicion and early detection and diagnosis for any pigmented gingival lesions cannot be overemphasised. Diagnosis must be based on thorough detailed history and valid histologic evidence. PMID:22368374

    2017-06-01

    Silent sinus syndrome is an unusual cause of progressive enophthalmos and hypoglobus due to atelectasia of the maxillary sinus associated with osteolysis of the orbital floor. This syndrome is classically idiopathic, but the term is also used to describe traumatic or iatrogenic (surgical orbital decompression) cases. We report the case of a 33-year-old man who presented with a left orbital trauma without functional disorder. Computed tomography (CT) scan revealed a nondisplaced fracture of the left orbital floor. No surgical indication was made. Three months later, the patient presented with progressive enophthalmos. CT revealed a complete lysis of the left orbital floor and a left maxillary sinus atelectasia. The original nondisplaced fracture of the orbital floor was not responsible for enophthalmos but the associated fracture of the left uncinate process that induced the closure of the left maxillary sinus infundibulum. This induced in turn hypoventilation of the sinus and a left orbital floor lysis. Treatment consisted in surgical opening of the maxillary sinus ostium and reconstruction of the orbital floor.

    An increased response to painful stimuli without spontaneous pain suggests a role of central hyperexcitability of pain pathways in the pathogenesis of myofascial pain syndrome (MPS). In this study we aimed to test the hypothesis that spinal pain pathways are affected in MPS. We used cutaneous silent period (CSP) parameters to demonstrate the hyperexcitability of spinal pain pathways in MPS. Twenty-nine patients diagnosed with MPS and 30 healthy volunteers were included in the study. The CSP recordings were performed in the right upper and left lower extremities. In both upper and lower extremities, patients had prolonged CSP latencies (P = 0.034 and P = 0.049 respectively) and shortened CSP durations (P = 0.009 and P = 0.008, respectively). Delayed and shortened CSP in MPS patients implies dysfunction in the inhibitory mechanism of the spinal/supraspinal pain pathways, suggesting central sensitization in the pathogenesis of MPS and supporting our research hypothesis.

    Full Text Available Reading act is performed by connected physiological, psychological and cognitive processes. The operations taking place in these processes are expected to continue for life by being developed with certain strategies. A lot of information is gained with reading skill in education life. Therefore, basic concepts that constitute reading education in teaching and improving reading are important for teachers. The aim of this study is to submit information compiled from the literature about reading education process and which basic concepts are used in reading education. While teaching reading from part to whole, from whole to part and interactional approaches are used. From part to whole approach is at the forefront. Then with interactional approach strategies, both code solving and making sense is improved. Teachers should know the characteristics of bouncing, stopping, turning back, and scanning movements of the eye both in code solving and making sense. The teacher should configure the teaching for the students to gain fluid reading elements by making use of reading out and reading silently. After reading act is acquired; good reader characteristics should be gained by improving asking questions, guessing, summarizing, interpretation skills in integrated readings. Reading skill is improved by studies on the text. Therefore, the students should come across texts that are suitable to their levels, textuality and readability criteria. The vocabulary of children should be improved in a planned way with text-based word and meaning studies. Fluid reading, making sense and interpretation skills of children should be pursued with different evaluation types. In the long term, work should be done to make reading a habit for them.

    The ECCIS project (Epidemiology and Clinic of Silent Ischemic Heart Disease) is an italian epidemiological study based on a population sample of 4,842 totally asymptomatic men aged 40-59 whose primary aim is the evaluation of the prevalence of totally silent myocardial ischemia and silent myocardial infarction. The systemic search for markers of silent ischemia and infarction was pursued along 3 screening stages: the 1st stage included resting electrocardiogram, hyperventilation test, exercise electrocardiogram and 24-hour Holter electrocardiogram; the 2nd stage included echocardiogram, thallium-201 scintigraphy in conjunction with exercise test or dypiridamole test, exercise radionuclide ventriculography and ergometrine test; the 3rd stage included coronary angiography. After the completion of the 1st stage procedures 439 men (9.1%) with abnormal results and low probability of disease were invited to the 2nd stage and 387 accepted to undergo the diagnostic procedures. After the completion of the 2nd stage, 104 men with moderate or high suspicion of silent myocardial ischemia or infarction were invited to perform coronary angiography but only 62 men accepted to undergo the 3rd stage procedures (participation rate 59.6%). The final diagnosis of totally silent myocardial ischemia or infarction on the basis of predefined criteria was established in 25 patients. The prevalence of silent ischemic heart disease on the overall original 4,842 men was 0.52% (95% CL, 0.32 and 0.72%), while the final estimate after adjusting for participation rates at 2nd and 3rd stages was 0.89% (95% CL, 0.6 and 1.1%). The results of the ECCIS study show that the prevalence of silent myocardial ischemia is definitely lower than that revealed by prior epidemiological studies in Norway and in USA.

    To investigate the silent circulation and transmission of arthropod-borne viruses (arboviruses) in the Fako Division of Cameroon. This survey was conducted based on clinical observations and laboratory diagnosis; field collections of mosquitoes. This study was conducted in the Fako Division of South West Cameroon. One hundred and two sera were obtained from febrile patients (with negative laboratory findings for malaria and typhoid fever) at clinics in the Fako Division, and diurnal anthropophilic mosquitoes (4,764) collected. Virus isolation was attempted from these, and sera were screened for antibodies against 18 African arboviruses by haemagglutination inhibition (HI) and complement fixation (CF) tests. No virus was isolated. Fifty three of 79 (67.1%) sera reacted with one or more viral antigens. Twenty nine sera (36.7%) reacted with members of the genus Alphavirus, with Chikungunya (CHIKV) and O'nyong-nyong (ONNV) viruses as the most frequent (34.2%). Forty six sera (58.2%) reacted with members of the genus Flavivirus: 24 (30.4%) were cross-reactive, but 11.4% reacted monotypically with Zika, 5.1% with yellow fever virus (YFV), 5.1% with dengue virus-2 (DENV-2), 2.5% with DENV-1 and 1.3% with Wesselsbron virus, respectively. The plaque reduction neutralisation test used to specify the agent that elicited the response could not resolve 33.3% of the cross reactions between CHIKV and ONNV. Neutralising antibody titres against ONNV and CHIKV were very high indicating probable re-infection. Our results indicate previously undetected circulation of arboviruses in Cameroon, and suggest that they are important, overlooked public health problems.

    Introduction Dyslexia is characterized by slow, inaccurate reading. Previous studies have shown that the Reading Acceleration Program (RAP) improves reading speed and accuracy in children and adults with dyslexia and in typical readers across different orthographies. However, the effect of the RAP on the neural circuitry of reading has not been established. In the current study, we examined the effect of the RAP training on regions of interest in the neural circuitry for reading using a lexical decision task during fMRI in children with reading difficulties and typical readers. Methods Children (8–12 years old) with reading difficulties and typical readers were studied before and after 4 weeks of training with the RAP in both groups. Results In addition to improvements in oral and silent contextual reading speed, training-related gains were associated with increased activation of the left hemisphere in both children with reading difficulties and typical readers. However, only children with reading difficulties showed improvements in reading comprehension, which were associated with significant increases in right frontal lobe activation. Conclusions Our results demonstrate differential effects of the RAP on neural circuits supporting reading in both children with reading difficulties and typical readers and suggest that the intervention may stimulate use of typical neural circuits for reading and engage compensatory pathways to support reading in the developing brain of children with reading difficulties.

    Purpose. We evaluated the impact of glaucoma-related vision loss on reading ability and reading engagement in 10 reading activities. Methods. A total of 63 glaucoma patients and 59 glaucoma suspect controls self-rated their level of reading difficulty for 10 reading items, and responses were analyzed using Rasch analysis to determine reading ability. Reading engagement was assessed by asking subjects to report the number of days per week they engaged in each reading activity. Reading restriction was determined as a decrement in engagement. Results. Glaucoma subjects more often described greater reading difficulty than controls for all tasks except puzzles (P reading tasks involved puzzles, books, and finances, while the least difficult reading tasks involved notes, bills, and mail. In multivariable weighted least squares regression models of Rasch-estimated person measures of reading ability, less reading ability was found for glaucoma patients compared to controls (β = −1.60 logits, P reading ability was associated with more severe visual field (VF) loss (β = −0.68 logits per 5-dB decrement in better-eye VF mean deviation [MD], P reading on 18% fewer days (P = 0.003) and newspaper reading on 10% fewer days (P = 0.008). No statistically significant reading restriction was observed for other reading activities (P > 0.05). Conclusions. Glaucoma patients have less reading ability and engage less in a variety of different reading activities, particularly those requiring sustained reading. Future work should evaluate the mechanisms underlying reading disability in glaucoma to determine how patients can maintain reading ability and engagement. PMID:25052992

    1996-06-01

    The relationship of subvocal speech and reading rate to comprehension of 25 children, ranging from 8 to 15 years of age, was investigated by means of electromyographic (EMG) recordings taken while the subjects silently read two meaningful passages. The first was orthographically regular, and the second was composed of approximately sixty percent homophones, Labial muscle action recordings, latencies, and comprehension measures were obtained. Variables derived from these measures were used to predict reading age. Profiles derived from the EMGs provided information about how each reader processed the information from the reading passages. The empirical results of the study provide strong support for the valuable role of subvocal speech in the extraction of information and the importance of readers demonstrating the ability to use flexibility of the reading process when reading for meaning.

    2013-06-01

    The concept of an internal forward model that internally simulates the sensory consequences of an action is a central idea in speech motor control. Consistent with this hypothesis, silent articulation has been shown to modulate activity of the auditory cortex and to improve the auditory identification of concordant speech sounds, when embedded in white noise. In the present study, we replicated and extended this behavioral finding by showing that silently articulating a syllable in synchrony with the presentation of a concordant auditory and/or visually ambiguous speech stimulus improves its identification. Our results further demonstrate that, even in the case of perfect perceptual identification, concurrent mouthing of a syllable speeds up the perceptual processing of a concordant speech stimulus. These results reflect multisensory-motor interactions during speech perception and provide new behavioral arguments for internally generated sensory predictions during silent speech production.

    2017-05-01

    Generally, teachers use oral communication for teaching mathematics. Taking an opposite perspective, this paper describes how instructional practices for mathematics can be carried out namely a silent method. Silent method uses body language, written, and oral communication for classroom interaction. This research uses a design research approach consisting of four phases: preliminary, prototyping and developing the instruction, and assessment. There are four stages of silent method. The first stage is conditioning stage in which the teacher introduces the method and makes agreement about the `rule of the game'. It is followed by the second one, elaborating stage, where students guess and explore alternative answers. The third stage is developing mathematical thinking by structuring and symbolizing. Finally, the method is ended by reinforcing stage which aims at strengthening and reflecting student's understanding. In this paper, every stage is described on the basis of practical experiences in a real mathematics classroom setting.

    We are at least as dream deprived as we are sleep deprived. Many of the health concerns attributed to sleep loss result from a silent epidemic of REM sleep deprivation. REM/dream loss is an unrecognized public health hazard that silently wreaks havoc with our lives, contributing to illness, depression, and an erosion of consciousness. This paper compiles data about the causes and extent of REM/dream loss associated with commonly used medications, endemic substance use disorders, rampant sleep disorders, and behavioral and lifestyle factors. It examines the consequences of REM/dream loss and concludes with recommendations for restoring healthy REM/dreaming. © 2017 New York Academy of Sciences.

    To shed light on a large but neglected human rights issue that can be termed passive participation in torture. This is a response to the rising number of statements from torture victims who claim that during their incarceration, medical personnel cooperated with the interrogators by sharing medical documents, giving false statements, and providing other indirect assistance to the interrogator. Cases studies are used to demonstrate the existence of passive participation, as well as situations where the passivity has been addressed and improved. Extracts of international instruments and actions undertaken by associations are used to help the reader address issues around the passive participation in torture. By reading this article medical professionals will be made aware that action can be undertaken with the help of existing international laws and policies. In the conclusion of the article a range of bullet-points is made available for medical professionals who want to address the issue of passive participation.

Intra-atrial growth has been reported in advanced, clinically manifested cases of liver carcinomas in African and Japanese subjects, but very occasionally in Caucasian people. Our case further suggests that this occurrence should also be considered in Western Countries.

  9. Determinants of Sir2-Mediated, Silent Chromatin Cohesion.

    Cohesin associates with distinct sites on chromosomes to mediate sister chromatid cohesion. Single cohesin complexes are thought to bind by encircling both sister chromatids in a topological embrace. Transcriptionally repressed chromosomal domains in the yeast Saccharomyces cerevisiae represent specialized sites of cohesion where cohesin binds silent chromatin in a Sir2-dependent fashion. In this study, we investigated the molecular basis for Sir2-mediated cohesion. We identified a cluster of charged surface residues of Sir2, collectively termed the EKDK motif, that are required for cohesin function. In addition, we demonstrated that Esc8, a Sir2-interacting factor, is also required for silent chromatin cohesion. Esc8 was previously shown to associate with Isw1, the enzymatic core of ISW1 chromatin remodelers, to form a variant of the ISW1a chromatin remodeling complex. When ESC8 was deleted or the EKDK motif was mutated, cohesin binding at silenced chromatin domains persisted but cohesion of the domains was abolished. The data are not consistent with cohesin embracing both sister chromatids within silent chromatin domains. Transcriptional silencing remains largely intact in strains lacking ESC8 or bearing EKDK mutations, indicating that silencing and cohesion are separable functions of Sir2 and silent chromatin.

    To study the predictive value of silent ischemia, a total of 132 patients with first transmural myocardial infarction were examined, 69 had anterior and 63 had inferior myocardial infarction. On days 8-12 of onset of the disease, all the patients underwent loading two-dimensional echocardiography along with transesophageal pacing, as well as polyposition coronary angiography. According to the echocardiographic findings, 3 groups of patients were identified: 1) 34 (25.8%) with painful ischemia; 2) 37 (28.0%) with silent ischemia; 3) 61 (46.2%) with a negative test. Ischemic alterations were more frequently seen in inferior (73%) than in anterior (36.2%) myocardial infarction. The patients with painful ischemia showed a lower threshold of ischemia occurrence, more severe and prolonged ST segment depression, and greater extent of an asynergic area than did the patients with silent ischemia. A 1-5-year (mean 2.4) follow-up revealed that in terms of the risk for postinfarction angina, recurrent myocardial infarction and fatal outcomes, patients with silent ischemia represent an intermediate group between those with painful ischemia and those who have a negative load test.

  17. Anamnesis and the Silent Narrator in Plato and John

    George L. Parsenios

    2017-03-01

    Full Text Available The Gospel of John is often compared to the dialogues of Plato by those who connect Johannine theology and Platonic philosophy. The comparison operates on the level of ideas. The present paper does not ignore issues of theology and philosophy but grounds a comparison of John and Plato first and foremost on the literary level. In several key places in John 1, 3, and 14, the Johannine narrator recedes from view and is unexpectedly silent where one would expect a narrator’s comment to organize the conversations and interactions between characters in John. Plato also renders the voice of the narrator silent in a dialogue like the Theaetetus. This paper argues that John and Plato both suppress the narrator’s voice in order to further their anamnetic efforts and to make later generations not only readers but participants in their original conversations.

  18. How can gynaecologists cope with the silent killer – osteoporosis?

    Directory of Open Access Journals (Sweden)

    Marian Szamatowicz

    2017-02-01

    Full Text Available Osteoporosis is a very common disease among women. It is frequently called a silent epidemic and, due to its impact on osteoporotic fractures with high morbidity and mortality, also a silent killer. There are a number of significant risk factors for osteoporosis, some of them very strongly related to the functioning of the reproductive system. These include menstrual irregularities, premature ovarian failure, early natural or surgical menopause, a high number of pregnancies, and long-term breast-feeding. Hence, there is every reason to include gynaecologists in the multidisciplinary team striving to cope with this dreadful disease. Calculation of the 10-year fracture risk, done by means of the FRAX calculator, and classification of women according to the level of risk could prove to be an effective method of limiting the negative effects of osteoporosis.

    An experimental study was made in this paper to investigate the relation between the places of the dielectric barriers, which cover the surfaces of the electrodes in the coaxial cylindrical reactors, and the rate of change of the electric power that is consumed in forming silent discharges. Therefore, silent discharges have been formed inside three coaxial cylindrical reactors. The dielectric barriers in these reactors were pasted on both the internal surface of the outer electrode in the first reactor and the external surface of the inner electrode in the second reactor as well as the surfaces of the two electrodes in the third reactor. The reactor under study has been fed by atmospheric air that flowed inside it with a constant rate at normal temperature and pressure, in parallel with the application of a sinusoidal ac voltage between the electrodes of the reactor. The electric power consumed in forming the silent discharges inside the three reactors was measured as a function of the ac peak voltage. The validity of the experimental results was investigated by applying Manley's equation on the same discharge conditions. The results have shown that the rate of consumption of the electric power relative to the ac peak voltage per unit width of the discharge gap improves by a ratio of either 26.8% or 80% or 128% depending on the places of the dielectric barriers that cover the surfaces of the electrodes inside the three reactors.

  3. The Voltan application programming environment for fail-silent processes

    Science.gov (United States)

    Black, D.; Low, C.; Shrivastava, S. K.

    1998-06-01

    The Voltan software library for building distributed applications provides the support for (i) a process pair to act as a single Voltan self-checking `fail-silent' process; and (ii) connection management for Voltan process communication. A Voltan fail-silent process is written by the application developer as a single threaded program. The Voltan system replicates this program transparently. The active replication of applications engenders problems when dealing with non-deterministic calculations. This paper outlines the mechanisms deployed by Voltan to deal with non-determinism. The current implementation can achieve a level of performance that is suitable for many real-time applications. The work described in this paper provides a way of solving the challenging problem of constructing fault-tolerant distributed computing systems capable of tolerating Byzantine failures, using general-purpose, low-cost components. The present practice is to employ hardware-based approaches to construct a `fail-silent' node using a self-checking processor pair working in lock-step. However, this approach is very costly in terms of the engineering effort required, and further, as processor speeds increase, keeping a pair in lock-step execution may prove difficult.

    This report presents a collection of models and control strategies developed and implemented in the power system simulation tool PowerFactory DIgSILENT for different wind turbine concepts. It is the second edition of Risoe-R-1400(EN) and it gathers and describes a whole wind turbine model database built-op and developed during several national research projects, carried out at Risoe DTU National Laboratory for Sustainable Energy and Aalborg University, in the period 2001-2007. The overall objective of these projects was to create a wind turbine model database able to support the analysis of the interaction between the mechanical structure of the wind turbine and the electrical grid during different operational modes. The report provides thus a description of the wind turbines modelling, both at a component level and at a system level. The report contains both the description of DIgSILENT built-in models for the electrical components of a grid connected wind turbine (e.g. induction generators, power converters, transformers) and the models developed by the user, in the dynamic simulation language DSL of DIgSILENT, for the non-electrical components of the wind turbine (wind model, aerodynamic model, mechanical model). The initialisation issues on the wind turbine models into the power system simulation are also presented. The main attention in the report is drawn to the modelling at the system level of the following wind turbine concepts: (1) Fixed speed active stall wind turbine concept (2) Variable speed doubly-fed induction generator wind turbine concept (3) Variable speed multi-pole permanent magnet synchronous generator wind turbine concept These wind turbine concept models can be used and even extended for the study of different aspects, e.g. the assessment of power quality, control strategies, connection of the wind turbine at different types of grid and storage systems. Different control strategies have been developed and implemented for these wind turbine

  11. Microsaccades during reading.

    Directory of Open Access Journals (Sweden)

    Norick R Bowers

    Full Text Available Recent research has shown that microsaccades contribute to high acuity vision. However, little is known about whether microsaccades also play a role in daily activities, such as reading, that do not involve stimuli at the limit of spatial resolution. While the functions of larger saccades in reading have been extensively examined, microsaccades are commonly regarded as oculomotor noise in this context. We used high-resolution eyetracking and precise gaze localization to investigate fine oculomotor behavior during reading. Our findings show that microsaccade characteristics differ from those measured during sustained fixation: microsaccades are larger in size and primarily leftwards during reading, i.e. they move the line of sight backward on the text. Analysis of how microsaccades shift gaze relative to the text suggests that these movements serve two important functions: (1 a corrective function, by moving the gaze regressively within longer words when the preceding saccade lands too far toward the end of these words, and (2 an exploratory function, by shifting the gaze on adjacent words to gain additional information before the execution of the next saccade. Thus, microsaccades may benefit reading by enhancing the visibility of nearby words. This study highlights the importance of examining fine oculomotor behavior in reading, and calls for further research to investigate the possible roles of microsaccades in reading difficulties.

    2013-05-01

    The objective of this study was to examine why rapid automatized naming (RAN) is related to reading by manipulating processes involved at the input, processing, and output stages of its production. In total, 65 children in Grade 2 and 65 in Grade 6 were assessed on serial and discrete RAN (Digits and Objects), Cancellation, RAN Yes/No, and oral and silent reading fluency. The results of regression analyses indicated that RAN is related to reading because both involve serial processing and oral production of the names of the stimuli. Copyright © 2012 Elsevier Inc.

    2015-12-01

    Recent evidence suggests that amblyopia results in fixation instability and atypical saccades. Reading is a vision-reliant ability that requires sequential eye movements, including forward and regressive saccades. This study investigated reading and associated eye movements in school-age amblyopic children. Amblyopic children with strabismus and/or anisometropia (n = 29) were compared to nonamblyopic children treated for strabismus (n = 23) and normal control children (n = 21). While fitted with the ReadAlyzer, an eye movement recording system, children silently read a grade-level paragraph of text during binocular viewing. Reading rate, number of forward and regressive saccades per 100 words, and fixation duration were determined. Comprehension was evaluated with a 10-item quiz; only data from children with at least 80% correct responses were included. Amblyopic children read more slowly and had more saccades compared with nonamblyopic children with treated strabismus and normal controls. Fixation duration did not differ significantly for amblyopic children versus normal controls. Treated strabismic children without amblyopia did not differ significantly from normal controls on any reading measure. Amblyopic eye visual acuity was not correlated with any reading measure. Amblyopia was associated with slower reading speed in school-age children. Treatment for monocular amblyopia visual acuity impairment could improve reading speed and efficiency.

    The purpose of this study was to identify and evaluate a universal screening battery for reading that is appropriate for older elementary students in a response to intervention model. Multiple measures of reading and reading correlates were administered to 230 fourth-grade children. Teachers rated children's reading skills, academic competence, and attention. Children were classified as not-at-risk or at-risk readers based on a three-factor model reflecting reading comprehension, word recognition/decoding, and word fluency. Predictors of reading status included group-administered tests of reading comprehension, silent word reading fluency, and teacher ratings of reading problems. Inclusion of individually administered tests and growth estimates did not add substantial variance. The receiver-operator characteristic curve analysis yielded an area under the curve index of 0.90, suggesting this model may both accurately and efficiently screen older elementary students with reading problems.

  16. The Rachel Carson Letters and the Making of Silent Spring

    Full Text Available Environment, conservation, green, and kindred movements look back to Rachel Carson’s 1962 book Silent Spring as a milestone. The impact of the book, including on government, industry, and civil society, was immediate and substantial, and has been extensively described; however, the provenance of the book has been less thoroughly examined. Using Carson’s personal correspondence, this paper reveals that the primary source for Carson’s book was the extensive evidence and contacts compiled by two biodynamic farmers, Marjorie Spock and Mary T. Richards, of Long Island, New York. Their evidence was compiled for a suite of legal actions (1957-1960 against the U.S. Government and that contested the aerial spraying of dichlorodiphenyltrichloroethane (DDT. During Rudolf Steiner’s lifetime, Spock and Richards both studied at Steiner’s Goetheanum, the headquarters of Anthroposophy, located in Dornach, Switzerland. Spock and Richards were prominent U.S. anthroposophists, and established a biodynamic farm under the tutelage of the leading biodynamics exponent of the time, Dr. Ehrenfried Pfeiffer. When their property was under threat from a government program of DDT spraying, they brought their case, eventually lost it, in the process spent US$100,000, and compiled the evidence that they then shared with Carson, who used it, and their extensive contacts and the trial transcripts, as the primary input for Silent Spring. Carson attributed to Spock, Richards, and Pfeiffer, no credit whatsoever in her book. As a consequence, the organics movement has not received the recognition, that is its due, as the primary impulse for Silent Spring, and it is, itself, unaware of this provenance.

    2014-09-01

    Compartment syndrome does not always present classically in the pediatric population, making clinical diagnosis uniquely challenging. The purpose of this study was to identify signs and symptoms of compartment syndrome that may help risk-stratify pediatric patients upon presentation, as well as to report outcomes of 'silent' compartment syndrome in children. A retrospective review of cases of 'silent' compartment syndrome at a level I pediatric trauma center between 2000 and 2010 was conducted. Patient demographics and clinical data were reviewed, including complications and patient outcomes. Radiographs taken at presentation, on intraoperative fluoroscopy, and at postoperative follow-up were reviewed for fracture type, and severity and outcome analyses. Five patients were found to have compartment syndrome without the presence of significant pain at rest or on passive range of motion. The study included three male and two female patients with a median age of 7 years. Three upper-extremity and two lower-extremity fractures were involved. The mean time from presentation to surgery was 14 h. At presentation, three of five patients had muscle paralysis, whereas at diagnosis of compartment syndrome, four of five had paralysis. Of the classic five P's, a maximum of two were found at diagnosis. The mean clinical follow-up period was 11 months (2-26 months). Long-term complications from compartment syndrome were found in one of five patients, who at the most recent follow-up, continued to be debilitated. This study reviews a series of cases of 'silent' compartment syndrome and confirms its atypical presentation. It is recommended that caution be used when assessing fractures with high risk for compartment syndrome in children, especially those complicated by nerve injury, as they do not always present in the classic manner, with missed diagnosis leading to significant functional deficits.

    This study aimed to assess the performance of a ''Silent'' zero time of echo (ZTE) sequence for T1-weighted brain imaging using a 7 T MRI system. The Silent sequence was evaluated qualitatively by two neuroradiologists, as well as quantitatively in terms of tissue contrast, homogeneity, signal-to-noise ratio (SNR) and acoustic noise. It was compared to conventional T1-weighted imaging (FSPGR). Adequacy for automated segmentation was evaluated in comparison with FSPGR acquired at 7 T and 1.5 T. Specific absorption rate (SAR) was also measured. Tissue contrast and homogeneity in Silent were remarkable in deep brain structures and in the occipital and temporal lobes. Mean tissue contrast was significantly (p < 0.002) higher in Silent (0.25) than in FSPGR (0.11), which favoured automated tissue segmentation. On the other hand, Silent images had lower SNR with respect to conventional imaging: average SNR of FSPGR was 2.66 times that of Silent. Silent images were affected by artefacts related to projection reconstruction, which nevertheless did not compromise the depiction of brain tissues. Silent acquisition was 35 dB(A) quieter than FSPGR and less than 2.5 dB(A) louder than ambient noise. Six-minute average SAR was <2 W/kg. The ZTE Silent sequence provides high-contrast T1-weighted imaging with low acoustic noise at 7 T. (orig.)

    The effect of increasing the number of scans in the "cluster" of an interleaved silent steady state (ISSS) fMRI imaging scheme from 1 to 2, and then to 3 was examined by a fixed-effects analysis of an auditory short-term memory task with four subjects. Compared to a cluster size of 1, a cluster of 2 scans improved sensitivity at detecting brain activity and statistical power, while a cluster of 3 scans further improved statistical power but seemed not to improve sensitivity beyond that achieved with a cluster of 2 scans. The findings reveal that cluster size is a vital parameter for an ISSS imaging scheme.

    A 79-year-old man complained progressive visual impairment and Diplopia for 2 weeks. A big pituitary tumor was found and partially removed by the surgeon eventually. The tumor cells were chromophobic with H&E stain and exhibited focal positive staining with PAS. Immunoperoxidase method demonstrated moderate positivity for adrenocorticotrophic hormone (ACTH), while staining for growth hormone (G.H) and prolactin were negative. The patient was eucorticoid clinically and biochemically. Since silent corticotropic adenoma of the human pituitary gland is rarely encountered clinically, a review of the literature is included in this article.

    In this study, we aimed to use both the probability-based and the frequency-based analyses methods simultaneously to examine cutaneous silent period (CSP) induced by strong electrical currents. Subjects were asked to contract their first dorsal interosseus muscles so that one motor unit monitored via intramuscular wire electrodes discharged at a rate of approximately 8 Hz. Strong electrical stimuli were delivered to the back of the hand that created a subjective discomfort level of between 4 and 7 [0-10 visual analogue scale] and induced cutaneous silent period in all units. It was found that the duration of the CSP was significantly longer when the same data were analysed using frequency-based analysis method compared with the probability-based methods. Frequency-based analysis indicated that the strong electrical stimuli induce longer lasting inhibitory currents than what was indicated using the probability-based analyses such as surface electromyogram and peristimulus time histogram. Usage of frequency-based analysis for bringing out the synaptic activity underlying CSP seems essential as its characteristics have been subject to a large number of studies in experimental and clinical settings.

    The primary purpose of this study was to explore if there could be a more beneficial method in organizing the individual instructional reading components (phonological decoding, spelling, fluency, and reading comprehension) within a remedial reading program to increase sensitivity to instruction for middle school students with reading disabilities (RD). Three different modules (Alternating, Integrated, and Additive) of the Reading Achievement Multi-Modular Program were implemented with 90 middle school (sixth to eighth grades) students with reading disabilities. Instruction occurred 45 min a day, 5 days a week, for 26 weeks, for approximately 97 h of remedial reading instruction. To assess gains, reading subtests of the Woodcock Johnson-III, the Gray Silent Reading Test, and Oral Reading Fluency passages were administered. Results showed that students in the Additive module outperformed students in the Alternating and Integrated modules on phonological decoding and spelling and students in the Integrated module on comprehension skills. Findings for the two oral reading fluency measures demonstrated a differential pattern of results across modules. Results are discussed in regards to the effect of the organization of each module on the responsiveness of middle school students with RD to instruction.

    Spelling is a challenge for individuals with dyslexia. Phoneme-to-grapheme correspondence rules are highly inconsistent in French, which make them very difficult to master, in particular for dyslexics. One recurrent manifestation of this inconsistency is the presence of silent letters at the end of words. Many of these silent letters perform a…

  7. Phonological coding during reading

    2014-01-01

    The exact role that phonological coding (the recoding of written, orthographic information into a sound based code) plays during silent reading has been extensively studied for more than a century. Despite the large body of research surrounding the topic, varying theories as to the time course and function of this recoding still exist. The present review synthesizes this body of research, addressing the topics of time course and function in tandem. The varying theories surrounding the function of phonological coding (e.g., that phonological codes aid lexical access, that phonological codes aid comprehension and bolster short-term memory, or that phonological codes are largely epiphenomenal in skilled readers) are first outlined, and the time courses that each maps onto (e.g., that phonological codes come online early (pre-lexical) or that phonological codes come online late (post-lexical)) are discussed. Next the research relevant to each of these proposed functions is reviewed, discussing the varying methodologies that have been used to investigate phonological coding (e.g., response time methods, reading while eyetracking or recording EEG and MEG, concurrent articulation) and highlighting the advantages and limitations of each with respect to the study of phonological coding. In response to the view that phonological coding is largely epiphenomenal in skilled readers, research on the use of phonological codes in prelingually, profoundly deaf readers is reviewed. Finally, implications for current models of word identification (activation-verification model (Van Order, 1987), dual-route model (e.g., Coltheart, Rastle, Perry, Langdon, & Ziegler, 2001), parallel distributed processing model (Seidenberg & McClelland, 1989)) are discussed.

    2010-12-01

    Full Text Available Speech / Wordless Writing: Language and German Silent Cinema Marc Silberman If language loses its communicative and interpretative functions in direct proportion to the loss of its referential grounding, then the modernist crisis is simultaneously a crisis of its signifying practices. This means that the evolution of the silent cinema is a particularly rich site to examine the problematic relationship of language and image. This essay presents several expressionist films as a specific response to this crisis in order to describe the diverse cinematic forms of resistance to the word, to articulated speech. While some film makers developed the silence of the silent film into a “gestural language” that dramatized light and movement, others reproduced the film figures’ silent speech by means of graphically stylized intertitles. My thesis is that the expressionist cinema maintained an idealistic notion of the film as a pure work of art that aimed at a unified composition of all elements and missed the opportunity to explore the rich semiotic possibilities of the new technological medium with its hybrid, synergetic forms and provocative force. Hence, the expressionist cinema marks a transition or even the endpoint of a long process of reflection about the communicative possibilities of language that shifted to a fundamentally new level with the invention of sound cinema at the end of the 1920s. Parole muette / écriture sans mot: Le langage et le cinéma allemand muet Marc Silberman Le langage, dit-on, perd de ses functions communicatrices et interpretatives en proportion directe à la perte de sa force référentielle. On dira que la crise moderniste est également une crise des pratiques signifiantes. Ce qui revient à dire aussi que l’évolution du cinéma muet serait une site particulièrement riche pour examiner les problématiques du langage vs. l’image.

    Full Text Available Incidence of spinal neurocysticercosis (NCC is rare. Isolated spinal NCC is still rarer. We present here a case report where a young lady presented with all the clinical features of pseudotumor cerebri (PTC, where medical treatment for PTC failed and the presence of cysticercous in spinal canal was detected only on the operation table, while doing a lumbo-peritoneal shunt (LP shunt to save her vision. Diagnosis could be confirmed only after the histopathology report was received. She did not have any direct evidence of spinal involvement, thereby eluding correct diagnosis. In English literature, we could not find any report of isolated and silent spinal NCC associated with PTC. In addition, we could not find any report of recovery of cysticercous larva through the Touhey′s needle injury, although this was an incidental finding. In endemic areas, isolated spinal NCC should be suspected in patients presenting with PTC.

    Given evidence that ischemic heart disease is the most frequent cause of death in patients with cerebrovascular disease, we used ergometrics to screen 80 patients with TIA for silent myocardial ischemia (SMI) at the neurological unit of Hospital Clínico Universitario in Zaragoza, Spain. The patients were compared with a control group of 80 with no signs of heart disease. Neither the patients nor the controls had ever shown clinical signs of coronary ischemia and their baseline electrocardiograms were normal. Stress test results were positive in 25 (31%) of the TIA patients, and in 4 (5%) (p Hiperlipidemia (75% testing positive versus 43% negative, p < 0.01) and diabetes (31% testing positive versus 13% negative, p < 0.01) were the risk factors statistically related with a positive stress test.

    Computerized lip reading, or speech reading, is concerned with the difficult task of converting a video signal of a speaking person to written text. It has several applications like teaching deaf and dumb to speak and communicate effectively with the other people, its crime fighting potential and invariance to acoustic environment. We convert the video of the subject speaking vowels into images and then images are further selected manually for processing. However, several factors like fast speech, bad pronunciation, and poor illumination, movement of face, moustaches and beards make lip reading difficult. Contour tracking methods and Template matching are used for the extraction of lips from the face. K Nearest Neighbor algorithm is then used to classify the 'speaking' images and the 'silent' images. The sequence of images is then transformed into segments of utterances. Feature vector is calculated on each frame for all the segments and is stored in the database with properly labeled class. Character recognition is performed using modified KNN algorithm which assigns more weight to nearer neighbors. This paper reports the recognition of vowels using KNN algorithms

  17. Effects of nonfiction guided interactive read-alouds and think-alouds on fourth grader's depth of content area science vocabulary knowledge and comprehension

    Hanna, Tania Tamara

    Effects of nonfiction guided interactive read-alouds and think-alouds as a supplement to basal science textbooks on three vocabulary measures, definitions, examples, and characteristics, and one multiple-choice comprehension measure were assessed for 127 fourth graders over three time periods: pretest, posttest, and a 2-week delayed posttest. Two of three fourth-grade elementary science teachers implemented a series of 12 content-enhanced guided interactive scripted lessons. Two of these teachers implemented two treatments each. The first condition employed basal science textbooks as the text for guided interactive read-alouds and think-alouds while the second treatment employed basal science textbooks in conjunction with nonfiction text sets as the texts for guided interactive read-alouds and think-alouds. The third teacher, guided by traditional lesson plans, provided students with silent independent reading instruction using basal science textbooks. Multivariate analyses of variance and analyses of variance tests showed that mean scores for both treatment groups significantly improved on definitions and characteristics measures at posttest and either stabilized or slightly declined at delayed posttest. The treatment-plus group lost considerably on the examples posttest measure. The treatment group improved mean scores on the examples posttest measure, outperforming the treatment-plus group and the control group. Alternately, the control group significantly improved on the delayed posttest examples measure. Additionally, the two groups implementing guided interactive read-alouds and think-alouds performed better than the independent reading group on multiple-choice comprehension measures at posttest and sustained those gains 2 weeks later on delayed posttests. Findings maintain the incremental nature of vocabulary acquisition and development research and emphasize the roles of listening and speaking as critical features for integrating vocabulary into long

    2017-03-01

    Three-dimensional time-of-flight magnetic resonance angiography (TOF MRA) has been widely used in clinics. TOF MRA can cause dephasing artifacts, which lead to an intraluminal signal decrease. Silent MRA is a novel imaging technique that uses arterial spin labeling to achieve an ultrashort echo time (uTE), which is expected to decrease these effects and allow for accurate assessment of the flow in blood vessels. This study quantified the accuracy of Silent MRA images for visualizing the turbulent flow in flow-phantom and in vivo studies. The vessel contrast and coefficients of variation (CVs) for Silent MRA and TOF MRA were compared using normal and stenosis phantoms. Then, we performed both types of MRA on seven healthy volunteers. In the phantom study, although the contrast in the TOF MRA images was low distal to the stenosis region and at a high flow velocity, the contrast in the Silent MRA images did not change under these conditions. Furthermore, the mean CV for Silent MRA was smaller than that for TOF MRA under stenosis conditions. In the in vivo study, the mean contrast and vessel uniformity were significantly higher for Silent MRA than for TOF MRA. Although Silent MRA has limited spatial resolution and requires additional imaging time, this method may have the potential to improve the image quality of the carotid artery.

    This study's purpose was two-fold: (a) to confirm differences in silent reading rates of individuals with and without traumatic brain injury (TBI) and (b) to determine the effect of text-to-speech (TTS) on reading comprehension and efficiency by individuals with TBI. Ten adults with severe TBI answered comprehension questions about written passages presented in three conditions: reading only (RO), listening to TTS presentation only (LO) or reading and listening to TTS simultaneously (RL). The researchers compared reading rate, comprehension accuracy and comprehension rate (efficiency) across conditions. Analysis revealed significantly slower silent reading rates for the participants with TBI than for readers without TBI (n = 75). Also, participants with TBI achieved higher comprehension accuracy for factual than inferential questions; however, no significant main effect for comprehension accuracy emerged across reading conditions. In contrast, using comprehension rate as the dependent measure, analysis confirmed a significant main effect for reading condition and question type; post-hoc pairwise comparisons revealed that the RL condition yielded higher comprehension rate scores than the RO condition. As a group, adults with TBI appear to benefit in reading efficiency when simultaneously listening to and reading written passages; however, differences exist that reinforce the importance of individualizing treatment.

  3. Imitated prosodic fluency predicts reading comprehension ability in good and poor high school readers

    Directory of Open Access Journals (Sweden)

    Mara Breen

    2016-07-01

    Full Text Available Researchers have established a relationship between beginning readers’ silent comprehension ability and their prosodic fluency, such that readers who read aloud with appropriate prosody tend to have higher scores on silent reading comprehension assessments. The current study was designed to investigate this relationship in two groups of high school readers: Specifically Poor Comprehenders (SPCs, who have adequate word level and phonological skills but poor reading comprehension ability, and a group of age- and decoding skill-matched controls. We compared the prosodic fluency of the two groups by determining how effectively they produced prosodic cues to syntactic and semantic structure in imitations of a model speaker’s production of syntactically and semantically varied sentences. Analyses of pitch and duration patterns revealed that speakers in both groups produced the expected prosodic patterns; however, controls provided stronger durational cues to syntactic structure. These results demonstrate that the relationship between prosodic fluency and reading comprehension continues past the stage of early reading instruction. Moreover, they suggest that prosodically fluent speakers may also generate more fluent implicit prosodic representations during silent reading, leading to more effective comprehension.

    Population-based studies have shown a heightened prevalence of clinically silent brain infarcts in subjects who have migraine with aura (MA). We sought to determine whether this association could be confirmed in young patients with cryptogenic ischemic stroke, and explored the role of patent foramen ovale (PFO) as a potential underlying mechanism. Patients were selected from a registry of young patients consecutively treated for ischemic stroke in a tertiary university hospital among those without definite cause of stroke. Patients with PFO were matched for age and gender with patients with normal atrial septum. Migraine and MA were evaluated after patient selection and matching. Silent brain infarcts were independently evaluated on MRI. We included 100 patients [60 men; mean age (SD), 44.8 years (8.3)], 50 patients with PFO. We found silent brain infarcts in 36 patients and MA in 13 patients. MA was more frequent in patients with silent brain infarcts than in patients without silent brain infarcts (25.0% vs. 6.3%; OR, 5; 95% CI, 1.4-17.6; P = 0.01). Traditional cardiovascular risk factors were not associated with silent brain infarcts. PFO was neither associated with MA (OR, 1.7; 95% CI, 0.5-5.3) nor silent brain infarcts (OR, 0.7; 95% CI, 0.3-1.5). The association of MA with silent brain infarcts was not altered after adjustment for PFO. Findings suggest that silent brain infarcts in young patients with cryptogenic stroke is associated with MA. We found no evidence for a mediating effect of PFO on this association. © 2013 The Author(s) European Journal of Neurology © 2013 EFNS.

    2015-09-01

    Crowding is a phenomenon that characterizes normal periphery limiting letter identification when other letters surround the signal. We investigated the nature of the reading limitation of crowding by analyzing eye-movement patterns. The stimuli consisted of two items varying across trials for letter spacing (spaced, unspaced and increased size), lexicality (words or pseudowords), number of letters (4, 6, 8), and reading modality (oral and silent). In Experiments 1 and 2 (oral and silent reading, respectively) the results show that an increase in letter spacing induced an increase in the number of fixations and in gaze duration, but a reduction in the first fixation duration. More importantly, increasing letter size (Experiment 3) produced the same first fixation duration advantage as empty spacing, indicating that, as predicted by crowding, only center-to-center letter distance, and not spacing per se, matters. Moreover, when the letter size was enlarged the number of fixations did not increase as much as in the previous experiments, suggesting that this measure depends on visual acuity rather than on crowding. Finally, gaze duration, a measure of word recognition, did not change with the letter size enlargement. No qualitative differences were found between oral and silent reading experiments (1 and 2), indicating that the articulatory process did not influence the outcome. Finally, a facilitatory effect of lexicality was found in all conditions, indicating an interaction between perceptual and lexical processing. Overall, our results indicate that crowding influences normal word reading by means of an increase in first fixation duration, a measure of word encoding, which we interpret as a modulatory effect of attention on critical spacing.

    2017-01-01

    Abstract Rationale: The Burkitt lymphoma (BL) is a very aggressive B-cell non-Hodgkin's lymphoma. It accounts for 34% of lymphoma cases in children. Patient concerns: We present the case of a 6-year-old boy diagnosed with BL, who presented multiple contrasting elements of the disease: silent symptomatology, without involvement of the bone marrow at first, but with multiorgan infiltration and a fast evolution, despite starting the treatment shortly after the symptoms appeared. Diagnoses: He was diagnosed with BL after immunophenotyping from the pleural fluid. Interventions: After a week from admission, chemotherapy was initiated according to protocol NH-BFM therapeutic group III—cytoreductive phase in the acute care ward and subsequently the AA 24 treatment. Outcomes: Following the treatment, the patient developed medullary aplasia and cutaneous toxicity. The patient's general state remained severe during the hospitalization. Lessons: Even though the prognosis of BL has improved over time (up to 90% survival rate), in this case the evolution was unfavorable. In our patient, the symptoms appeared abruptly. They appeared late in the phase of multiple-organ dissemination, which generated the pessimistic prognosis. PMID:28700504

    To investigate the cutaneous silent period (CSP), a spinal inhibitory reflex mainly mediated by A-delta fibres, in demyelinating and axonal polyneuropathy (PNP) and evaluate whether CSP parameters differ between patients with and without neuropathic pain. Eighty-four patients with demyelinating PNP, 178 patients with axonal PNP and 265 controls underwent clinical examination, DN4 questionnaire, standard nerve conduction study, motor-root stimulation and CSP recordings from abductor digiti minimi. We calculated the afferent conduction time of CSP (a-CSP time) with the formula: CSP latency-root motor evoked potential latency. In the demyelinating PNP group the a-CSP time was significantly longer; in the axonal PNP group, CSP duration was shorter than the demyelinating group (p=0.010) and controls (p=0.001). CSP parameters were not different between patients with and without neuropathic pain. The abnormality of a-CSP time in the demyelinating PNP group suggests the crucial role of A-delta fibres in the mechanism of CSP; the shorter CSP duration in the axonal PNP group supports the strong influence of the number of axons on this parameter. Our study suggests that neuropathic pain could be related to pathophysiological mechanisms differing from mere A-delta fibre loss. CSP evaluation is effective in detecting A-delta fibre dysfunction in axonal as well as demyelinating PNP. Copyright © 2014 International Federation of Clinical Neurophysiology.

    2017-04-01

    Heart failure with reduced ejection fraction (HFrEF) is a progressive disorder whereby cardiac structure and function continue to deteriorate, often despite the absence of clinically apparent signs and symptoms of a worsening disease state. This silent yet progressive nature of HFrEF can contribute to the increased risk of death-even in patients who are 'clinically stable', or who are asymptomatic or only mildly symptomatic-because it often goes undetected and/or undertreated. Current therapies are aimed at improving clinical symptoms, and several agents more directly target the underlying causes of disease; however, new therapies are needed that can more fully address factors responsible for underlying progressive cardiac dysfunction. In this review, mechanisms that drive HFrEF, including ongoing cardiomyocyte loss, mitochondrial abnormalities, impaired calcium cycling, elevated LV wall stress, reactive interstitial fibrosis, and cardiomyocyte hypertrophy, are discussed. Additionally, limitations of current HF therapies are reviewed, with a focus on how these therapies are designed to counteract the deleterious effects of compensatory neurohumoral activation but do not fully prevent disease progression. Finally, new investigational therapies that may improve the underlying molecular, cellular, and structural abnormalities associated with HF progression are reviewed. © 2016 The Authors.

    Mexican male to female transgender asylum seekers in the United States suffer from serious health issues that can be attributed to stressors related to their transgender, ethnic minority, and socioeconomic status. This study explored these stressors, the resulting health issues, and the needs of this particularly vulnerable population. Asylum seekers' (n = 45) sworn declarations and psychological evaluations were examined by a multidisciplinary research team using a systematic document review process. The review identified stressors that occurred both in Mexico and the United States: verbal, physical, and sexual assaults; unstable environments; fear for safety/security; hiding undocumented status; and economic insecurity. The health issues that resulted in part from these stressors include posttraumatic stress disorder, depression, anxiety, sleep issues, isolation, avoidance, drug/alcohol use, and suicidal tendencies. Despite suffering from multiple health issues, asylum seekers rarely sought health or social services. Health promotion practitioners can play an important role in serving this silent minority by (1) expanding community-based research focused on the intersection of transgender, ethnic minority, and socioeconomic status; (2) using trusted community members to connect this population to necessary resources; (3) providing communication training/resource development for health care providers; and (4) creating a network of service organizations that understand the needs of transgender asylum seekers.

  12. Silent angels the genetic and clinical aspects of Rett syndrome

    2016-12-01

    Full Text Available Rett syndrome is a neurodevelopmental genetic disorder and, because of some behavioral characteristics, individuals affected by the disease are known as silent angels. Girls with Rett syndrome perform stereotyped movements, they have learning difficulties, their reaction time is prolonged, and they seem alienated in the environment. These children require constant pediatric, neurological and orthopedic care. In the treatment of Rett syndrome physical therapy, music therapy, hydrotherapy, hippotherapy, behavioral methods, speech therapy and diet, are also used. In turn, psychological therapy of the syndrome is based on the sensory integration method, using two or more senses simultaneously. In 80% of cases, the syndrome is related to mutations of the MECP2 gene, located on chromosome X. The pathogenesis of Rett syndrome is caused by the occurrence of a non-functional MeCP2 protein, which is a transcription factor of many genes, i.e. Bdnf, mef2c, Sgk1, Uqcrc1. Abnormal expression of these genes reveals a characteristic disease phenotype. Clinical symptoms relate mainly to the nervous, respiratory, skeletal and gastrointestinal systems. Currently causal treatment is not possible. However, researchers are developing methods by which, perhaps in the near future, it will be possible to eliminate the mutations in the MECP2 gene, and this will give a chance to the patient for normal functioning.

    Full Text Available Objective: The purpose of this study is to describe the clinical and radiological features of SSS, and to review therapeutic possibilities and their outcomes.Patients and Methods: Retrospective observational case series in the department of Arthur Vernes Institute between Mars 2007 and  Novembre 2012. Clinical records, including ophthalmology and otolaryngology evaluations as well as computed tomography scans and operative reports, were carefully examined. A literature review for relevant studies was performed to examine similar cases.Results: Eleven cases of  SSS were identified. Nine men and two women (sex ratio 4.5, aged between 23 and 54 years (mean, 30 years. there was 3 to 4 mm enophthalmos in 10 cases (90.9%, and hypoglobus in all cases, with no effect on visual function. In all 11 cases, the maxillary roof (orbital floor was drawn downwards, and the one or more walls of the maxilla were concave. In 4 cases septal deviation was present. 8 patients (72.7% underwent endoscopic sinus surgery, while 3 refused it. Septoplasty was performed in 4 cases (36.3%.Conclusion: The silent sinus syndrome is a rare entity. It mainly presents as unilateral enophthalmos in younger people and has very characteristic clinical and radiologic signs.This case series reports our diagnostic and therapeutic experience with this syndrome.

  14. Capeverdean reflexives: the importance of a silent Voice

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available In Capeverdean, a Portuguese-based Creole language, many reflexive contexts do not show any overt reflexive expression. This is the case of transitive verbs like bisti ‘dress’ in simple clauses: Ana bisti ‘Ana has dressed herself’. This is a perplexing fact, given that there is an anaphor of the SELF-type available in the language: (si kabesa — literally ‘his/her head’ —, meaning ‘himself/ herself’, which participates in reflexive clauses with other verbs. The current paper explores this puzzle, en-ding with a proposal supported empirically and also by recent studies for other languages. This novel analysis goes as follows: all Capeverdean finite sentences, except unaccusatives, have a Voice head, responsible for assigning external theta-roles. This also includes mid-dles, passives and this type of reflexives. It is this Voice head that, in spite of being silent, attracts the internal argument to a preverbal position and provides the interpretation for an implicit external argument, which is syntactically active.

    Ictus is a complication in patients with Sickle Cell Anemia (SCA), in these is of importance the precocious diagnosis of Silent Cerebral Infarcts (SCI). To determine the incidence of ICS in patients with SCA without neurological symptoms but with images in Cerebral Magnetic Resonance (RMC). A total of 18 patients (13 males, 5 females) with ages between 5 and 24 years (11.5 4,9), without history of neurological alterations, taken care at the Instituto Hematol gico de Occidente Banco de Sangre, Estado Zulia Venezuela. Methods. A clinical history was made to each patient in addition to detailed physical and neurological examinations that included the state of mind, conscience, language, sensitivity, cranial pairs, muscular force, reflexes, cerebella tests, neck and march. Later, RMC studies were carried out. It was found that 2/18 (11,1%) patients without neurological manifestations showed alterations in the RMC and they were diagnosed as ICS. The findings by images showed asymmetry of lateral ventricles and one of them showed gliosis as well. 11,1% of the all the studied cases (2/18) showed SCI, for what is suggested to carry out neurological evaluation and images, once a year, and to offer opportune therapies, for their impact in the function neurocognitive

    We examined the prominent theoretical explanations of the RAN-reading relationship in a relatively transparent language (Greek) in a sample of children (n = 286) followed from Grade 1 to Grade 2. Specifically, we tested the fit of eight different models, as defined by the type of reading performance predicted (oral vs. silent word reading fluency), the type of RAN tasks (non-alphanumeric vs. alphanumeric), and the RAN effects (direct vs. indirect). Working memory, attention, processing speed, and motor skills were used as “common cause” variables predicting both RAN and reading fluency and phonological awareness and orthographic processing were used as mediators of RAN's effects on reading fluency. The findings of both concurrent and longitudinal analyses indicated that RAN is a unique predictor of oral reading fluency, but not silent reading fluency. Using alphanumeric or non-alphanumeric RAN did not particularly affect the RAN-reading relationship. Both phonological awareness and orthographic processing partly mediated RAN's effects on reading fluency. Theoretical implications of these findings are discussed. PMID:27605918

    2013-01-01

    We examined whether different encounters of reading material influence the likelihood of mind wandering, memory for the material, and the ratings of interest in the material. In a within-subjects design participants experienced three different reading encounters: (1) reading a passage aloud, (2) listening to a passage being read to them, and (3) reading a passage silently. Throughout each reading encounter probes were given in order to identify mind wandering. After finishing the passage participants also rated how interesting it was and completed a content recognition test. Results showed that reading aloud led to the least amount of mind wandering, while listening to the passage led to the most mind wandering. Listening to the passage was also associated with the poorest memory performance and the least interest in the material. Finally, within the silent reading and listening encounters we observed negative relations between mind wandering and both memory performance and interest in the material, replicating previous findings. Taken together, the present findings improve our understanding of the nature of mind wandering while reading, and have potentially important implications for readers seeking to take advantage of the convenience of audiobooks and podcasts.

  1. Impact of classroom noise on reading and vocabulary skills in elementary school-aged children

    Science.gov (United States)

    Allen, Prudence; Brogan, Nashlea; Allan, Chris

    2004-05-01

    Classroom noise levels often exceed recommendations and, in large scale retrospective studies, it has been suggested that higher noise levels often correlate significantly with poorer academic performance [e.g., Shield., et al. (2002)]. However, experimental data on the performance of individual children are limited. This study therefore examined the effect of noise on the performance of children in grades 3-4 and 7-8 on standardized tests of oral reading, silent reading, and vocabulary (the Gray Oral Reading Test, the Gray Silent Reading Test, and the Peabody Picture Vocabulary Test). Each child completed parallel forms of a test in quiet and in classroom noise presented at 60 dB SPL. Required speech was presented at +10 S/N. Results from grouped data showed significantly reduced performance in noise only on the silent reading task and only for the older group of children. However, across tasks, when the effects of noise were evaluated as a function of childrens quiet performance levels, the noise effect was shown to be significant for the children performing at above average levels in quiet. These findings suggest that the effect of classroom noise may vary significantly across tasks and children. [Work supported by CLLRNet.

    Differences in how writing systems represent language raise important questions about whether there could be a universal functional architecture for reading across languages. In order to study potential language differences in the neural networks that support reading skill, we collected fMRI data from readers of alphabetic (English) and morpho-syllabic (Chinese) writing systems during two reading tasks. In one, participants read short stories under conditions that approximate natural reading, and in the other, participants decided whether individual stimuli were real words or not. Prior work comparing these two writing systems has overwhelmingly used meta-linguistic tasks, generally supporting the conclusion that the reading system is organized differently for skilled readers of Chinese and English. We observed that language differences in the reading network were greatly dependent on task. In lexical decision, a pattern consistent with prior research was observed in which the Middle Frontal Gyrus (MFG) and right Fusiform Gyrus (rFFG) were more active for Chinese than for English, whereas the posterior temporal sulcus was more active for English than for Chinese. We found a very different pattern of language effects in a naturalistic reading paradigm, during which significant differences were only observed in visual regions not typically considered specific to the reading network, and the middle temporal gyrus, which is thought to be important for direct mapping of orthography to semantics. Indeed, in areas that are often discussed as supporting distinct cognitive or linguistic functions between the two languages, we observed interaction. Specifically, language differences were most pronounced in MFG and rFFG during the lexical decision task, whereas no language differences were observed in these areas during silent reading of text for comprehension.

    Seaber, Emma

    2016-01-01

    This article explores the relationship between eating disorders and reading behaviors, arguing that there is a meaningful difference in a minority of readers' approach to and understanding of anorexia life-writing, and of literary texts more broadly. To illuminate this distinction, this article begins by considering the reported deleterious influence of Marya Hornbacher’s anorexia memoir, Wasted, elaborating the ways Hornbacher offers a positive presentation of anorexia nervosa that may, intentionally or not, induce certain readers to “try it” themselves. This is followed by an exploration of how Hornbacher’s own reading praxis is implicated in a discursive feedback loop around anorexia narratives. It concludes with a discussion of disordered reading attitudes in relation to the emergence of the “pro-anorexia” phenomenon. PMID:28569728

    We have often observed silent subcortical brain lesions on CT or MRI in first-ever ischemic stroke, but there is little published information on the relationship of these lesions to stroke subtypes. Here, we describe the incidence of MRI-detected silent subcortical brain lesions, including infarctions and white matter lesions, in a series of patients with first-ever ischemic stroke classified according to stroke subtypes. We also discuss the pathogenesis of these silent subcortical lesions. We evaluated 171 patients with acute first-ever ischemic stroke. The subjects were divided into three groups: lacunar, atherothrombotic and cardioembolic infarction groups. We evaluated silent subcortical brain infarction (SSBI), enlargement of perivascular space (EPS), and other white-matter lesions using MRI. Hypertension was observed in 67.6% of lacunar infarction, 57.1% of atherosclerotic infarction, and 54.1% of cardioembolic infarction. SSBI was more frequently observed in lacunar infarction than the others (lacunar vs. atherothrombotic vs. cardiogenic infarction, 81.5% vs. 44.4% vs. 42.1%, p=0.006). High-grade EPS (grade 2 or higher) was also observed more frequently in lacunar infarction than in the others (lacunar vs. atherothrombotic vs. cardiogenic infarction, 63.3% vs. 24.2% vs. 0%, p<0.001). Scheltens' score of silent subcortical lesions was significantly higher in lacunar infarction than in the others. The frequency of silent subcortical ischemic brain lesions was significantly higher in lacunar infarction than in atherosclerotic or cardioembolic infarction. We suggest that the pathogenesis of silent subcortical ischemic brain lesions is common to that of lacunar infarction, that is, small-vessel vasculopathy. (author)

  10. The Right to Remain Silent in Criminal Trial

    Directory of Open Access Journals (Sweden)

    Gianina Anemona Radu

    2013-05-01

    Full Text Available A person's right not to incriminate oneself or to remain silent and not contribute to their own incrimination is a basic requirement of due process, although the right not to testify against oneself is not expressly guaranteed. This legal right is intended to protect the accused/ the defendant against the authorities’ abusive coercion. The scope of the right not to incriminate oneself is related to criminal matter under the Convention, and thus susceptible or applicable to criminal proceedings concerning all types of crimes as a guarantee to a fair trial. The European Court of Justice ruled that despite the fact that art. 6 paragraph 2 of the Convention does not expressly mention the right not to incriminate oneself and the right not to contribute to their own incrimination (nemo tenetur are ipsum accusare these are generally recognized international rules that are in consistence with the notion of “fair trial” stipulated in art. 6. By virtue of the right to silence, the person charged with a crime is free to answer the questions or not, as he/she believes it is in his/her interest. Therefore, the right to silence involves not only the right not to testify against oneself, but also the right of the accused/ defendant not to incriminate oneself. Thus, the accused/defendant cannot be compelled to assist in the production of evidence and cannot be sanctioned for failing to provide certain documents or other evidence. Obligation to testify against personal will, under the constraint of a fine or any other form of coercion constitutes an interference with the negative aspect of the right to freedom of expression which must be necessary in a democratic society. It is essential to clarify certain issues as far as this right is concerned. First of all, the statutory provision in question is specific to adversarial systems, which are found mainly in Anglo-Saxon countries and are totally different from that underlying the current Romanian Criminal

  11. Periodic letter strokes within a word affect fixation disparity during reading.

    We investigated the way in which binocular coordination in reading is affected by the spatial structure of text. Vergence eye movements were measured (EyeLink II) in 32 observers while they read 120 single German sentences (Potsdam Sentence Corpus) silently for comprehension. The similarity in shape between the neighboring strokes of component letters, as measured by the first peak in the horizontal auto-correlation of the images of the words, was found to be associated with (i) a smaller minimum fixation disparity (i.e. vergence error) during fixation; (ii) a longer time to reach this minimum disparity and (iii) a longer overall fixation duration. The results were obtained only for binocular reading: no effects of auto-correlation could be observed for monocular reading. The findings help to explain the longer reading times reported for words and fonts with high auto-correlation and may also begin to provide a causal link between poor binocular control and reading difficulties.

    Full Text Available The institution of the silent partnership is not currently regulated by any legal act in the Polish legal system, although its importance in practice is not in doubt. As every action made in the economic sphere and economic execution of the contract is associated with specific effects on the basis of the tax laws. However, due to the lack of statutory regulation of the institution of silent partnership problematic is the question of determining the effects of tax legislation. Therefore, special attention is needed to determine the issue of these effects on the basis of income tax, tax on goods and services, transfer tax and the tax on inheritance and donations, as well as the question of liability for the tax liabilities of the silent partnership.

    Full Text Available Abstract. The degree of immunity to polioviruses of three serotypes among children of different ages was analysed on certain "controlled" and "silent" territories of Russia in different periods of Polio Eradication Initiative. It was shown that the levels of immunity of children’s population to polioviruses on "controlled" and "silent" territories had no significant difference. It was stated that on the phase which preceded the certification for the absence of circulation of wild polioviruses, when the National Immunisation Days were conducted in the country, the percentage of eronegative children to polioviruses of different serotypes was low on all the territories of Russia. After Russia as a part of the WHO European region was certified as a polio free country and mass immunisation was stopped thepercentage of seronegative children increased, especially to poliovirus of serotype 3, both on the "controlled" and on the "silent" territories.

  18. Eye movements while viewing narrated, captioned, and silent videos

    Science.gov (United States)

    Ross, Nicholas M.; Kowler, Eileen

    2013-01-01

    Videos are often accompanied by narration delivered either by an audio stream or by captions, yet little is known about saccadic patterns while viewing narrated video displays. Eye movements were recorded while viewing video clips with (a) audio narration, (b) captions, (c) no narration, or (d) concurrent captions and audio. A surprisingly large proportion of time (>40%) was spent reading captions even in the presence of a redundant audio stream. Redundant audio did not affect the saccadic reading patterns but did lead to skipping of some portions of the captions and to delays of saccades made into the caption region. In the absence of captions, fixations were drawn to regions with a high density of information, such as the central region of the display, and to regions with high levels of temporal change (actions and events), regardless of the presence of narration. The strong attraction to captions, with or without redundant audio, raises the question of what determines how time is apportioned between captions and video regions so as to minimize information loss. The strategies of apportioning time may be based on several factors, including the inherent attraction of the line of sight to any available text, the moment by moment impressions of the relative importance of the information in the caption and the video, and the drive to integrate visual text accompanied by audio into a single narrative stream.

    OBJECTIVE: The cortical silent period refers to a period of near silence in the electromyogram (EMG) after transcranial magnetic stimulation (TMS) of the motor cortex during contraction. However, low-level EMG of unknown origin is often present. We hypothesised that it arises through spinal...... reflexes. Sudden lengthening of the muscle as force drops during the silent period could excite muscle spindles and facilitate motoneurones.

Most of the recorded organisms (96.8% belong to Odonata (dragonflies and damselflies, Heteroptera (bugs, Diptera (flies, Coleoptera (beetles and Trichoptera (caddisflies. The study reports the first record of toe-winged beetle larvae (Ptilodactylidae in a tree hole aquatic habitat. The most significant observation is the prolific occurrence of trichopteran larvae as the second most abundant taxa in tree holes of Silent Valley National Park, and this stands as the first comprehensive record of the entire order in the habitat studied. The study upholds the importance of less explored microhabitats in the Western Ghats region in terms of sustaining unique community composition in the most delicate and extreme habitat conditions. It also puts forward important ecological research questions on biodiversity ecosystem functionality which could impart important lessons for managing and conserving the diminishing tropical evergreen forests which are significant for these unique habitats.

  8. Processing implicit control: evidence from reading times

    Directory of Open Access Journals (Sweden)

    Full Text Available Sentences such as The ship was sunk to collect the insurance exhibit an unusual form of anaphora, implicit control, where neither anaphor nor antecedent is audible. The nonfinite reason clause has an understood subject, PRO, that is anaphoric; here it may be understood as naming the agent of the event of the host clause. Yet since the host is a short passive, this agent is realized by no audible dependent. The putative antecedent to PRO is therefore implicit, which it normally cannot be. What sorts of representations subserve the comprehension of this dependency? Here we present four self-paced reading time studies directed at this question. Previous work showed no processing cost for implicit versus explicit control, and took this to support the view that PRO is linked syntactically to a silent argument in the passive. We challenge this conclusion by reporting that we also find no processing cost for remote implicit control, as in: The ship was sunk. The reason was to collect the insurance. Here the dependency crosses two independent sentences, and so cannot, we argue, be mediated by syntax. Our Experiments 1-4 examined the processing of both implicit (short passive and explicit (active or long passive control in both local and remote configurations. Experiments 3 and 4 added either three days ago or just in order to the local conditions, to control for the distance between the passive and infinitival verbs, and for the predictability of the reason clause, respectively. We replicate the finding that implicit control does not impose an additional processing cost. But critically we show that remote control does not impose a processing cost either. Reading times at the reason clause were never slower when control was remote. In fact they were always faster. Thus efficient processing of local implicit control cannot show that implicit control is mediated by syntax; nor, in turn, that there is a silent but grammatically active argument in passives.

    2008-06-01

    The aim of the study was to evaluate the long-term effects of antidepressive therapy on chronic pain and related disability, and masseter silent period in psychiatric depressive patients with temporomandibular disorders (TMD). The study included hospitalized psychiatric depressive patients on antidepressive therapy protocol (tetracyclic antidepressant-maprotiline and anxiolytic-diazepam) (n=30) and non-psychiatric patients seeking prosthodontic treatment (control group, n=38). TMD were diagnosed by Research Diagnostic Criteria for temporomandibular disorders proposed by Dworkin and LeResche. The surface electromyography was recorded from left and right masseter muscles and masseter inhibitory reflex (masseter silent period) was recorded after mechanical stimulation. The incidence of TMD appearance was very similar, of approximately 40% in both group of patients. The results of the study also indicated a higher prevalence of joint related TMD, a lower prevalence of muscular subtype of TMD and a lower grade of chronic pain and related disability in the psychiatric group of patients on antidepressive therapy in comparison with findings in the control group. In the patients on antidepressive therapy with TMD masseter silent period was not prolonged , while in the control group of patients with TMD the prolongation of the silent period was observed. The study provided evidence that long-term, combined therapy (maprotiline and diazepam) in psychiatric depressive patients significantly modulated signs and symptoms of TMD in comparison with the control group.

    Overt symptomatic atrial fibrillation (AF) occurs in over 20% of patients with hypertrophic cardiomyopathy (HC) leading to impaired quality of life, loss of productivity, and the risk for embolic stroke. However, the overall burden presented by AF in the HC population is unresolved due to the unknown frequency of silent asymptomatic episodes that do not necessarily achieve clinical recognition but nevertheless may have important disease-related implications. Therefore, stored electrograms were analyzed retrospectively for AF in 75 consecutive patients with HC (without AF history) implanted with dual-chamber cardioverter-defibrillators. Patients were followed for 5.0 ± 4.1 years at the Tufts Medical Center HCM Institute; ages were 50 ± 15 years, and 55% were male. Implantable cardioverter-defibrillator interrogation in the 75 patients showed AF to be absent in 54 (72%), 18 (24%) had clinically silent AF episodes, and the remaining 3 (4%) without previous asymptomatic episodes developed symptomatic and clinically overt paroxysmal AF. Of the 18 patients with clinically silent AF, 8 developed symptomatic AF, 4.1 ± 1.5 years later. Nonfatal embolic stroke occurred in 1 patient associated with asymptomatic AF and without other risk factors. In conclusion, clinically silent AF appears to be common in HC, occurring in almost 25% of patients. Such asymptomatic episodes of AF have important future implications, including potential thromboembolic risk, and development of symptomatic and clinically overt AF requiring prophylactic anticoagulation.

  1. Blind Speakers Show Language-Specific Patterns in Co-Speech Gesture but Not Silent Gesture.

    Sighted speakers of different languages vary systematically in how they package and order components of a motion event in speech. These differences influence how semantic elements are organized in gesture, but only when those gestures are produced with speech (co-speech gesture), not without speech (silent gesture). We ask whether the cross-linguistic similarity in silent gesture is driven by the visuospatial structure of the event. We compared 40 congenitally blind adult native speakers of English or Turkish (20/language) to 80 sighted adult speakers (40/language; half with, half without blindfolds) as they described three-dimensional motion scenes. We found an effect of language on co-speech gesture, not on silent gesture-blind speakers of both languages organized their silent gestures as sighted speakers do. Humans may have a natural semantic organization that they impose on events when conveying them in gesture without language-an organization that relies on neither visuospatial cues nor language structure. © 2017 Cognitive Science Society, Inc.

  2. Characterisation of silent and active genes for a variable large protein of Borrelia recurrentis

    Full Text Available Abstract Background We report the characterisation of the variable large protein (vlp gene expressed by clinical isolate A1 of Borrelia recurrentis; the agent of the life-threatening disease louse-borne relapsing fever. Methods The major vlp protein of this isolate was characterised and a DNA probe created. Use of this together with standard molecular methods was used to determine the location of the vlp1B. recurrentis A1 gene in both this and other isolates. Results This isolate was found to carry silent and expressed copies of the vlp1B. recurrentis A1 gene on plasmids of 54 kbp and 24 kbp respectively, whereas a different isolate, A17, had only the silent vlp1B. recurrentis A17 on a 54 kbp plasmid. Silent and expressed vlp1 have identical mature protein coding regions but have different 5' regions, both containing different potential lipoprotein leader sequences. Only one form of vlp1 is transcribed in the A1 isolate of B. recurrentis, yet both 5' upstream sequences of this vlp1 gene possess features of bacterial promoters. Conclusion Taken together these results suggest that antigenic variation in B. recurrentis may result from recombination of variable large and small protein genes at the junction between lipoprotein leader sequence and mature protein coding region. However, this hypothetical model needs to be validated by further identification of expressed and silent variant protein genes in other B. recurrentis isolates.

  5. The Nuts and Bolts of Transcriptionally Silent Chromatin in Saccharomyces cerevisiae

    Science.gov (United States)

    Gartenberg, Marc R.; Smith, Jeffrey S.

    2016-01-01

    Transcriptional silencing in Saccharomyces cerevisiae occurs at several genomic sites including the silent mating-type loci, telomeres, and the ribosomal DNA (rDNA) tandem array. Epigenetic silencing at each of these domains is characterized by the absence of nearly all histone modifications, including most prominently the lack of histone H4 lysine 16 acetylation. In all cases, silencing requires Sir2, a highly-conserved NAD+-dependent histone deacetylase. At locations other than the rDNA, silencing also requires additional Sir proteins, Sir1, Sir3, and Sir4 that together form a repressive heterochromatin-like structure termed silent chromatin. The mechanisms of silent chromatin establishment, maintenance, and inheritance have been investigated extensively over the last 25 years, and these studies have revealed numerous paradigms for transcriptional repression, chromatin organization, and epigenetic gene regulation. Studies of Sir2-dependent silencing at the rDNA have also contributed to understanding the mechanisms for maintaining the stability of repetitive DNA and regulating replicative cell aging. The goal of this comprehensive review is to distill a wide array of biochemical, molecular genetic, cell biological, and genomics studies down to the “nuts and bolts” of silent chromatin and the processes that yield transcriptional silencing.

    While eye movements were recorded and brains scanned, 29 children with and without specific learning disabilities (SLDs) decided if sentences they read (half with only correctly spelled words and half with homonym foils) were meaningful. Significant main effects were found for diagnostic groups (non-SLD control, dysgraphia control, and dyslexia) in total fixation (dwell) time, total number of fixations, and total regressions in during saccades; the dyslexia group had longer and more fixations and made more regressions in during saccades than either control group. The dyslexia group also differed from both control groups in (a) fractional anisotropy in left optic radiation and (b) silent word reading fluency on a task in which surrounding letters can be distracting, consistent with Rayner's selective attention dyslexia model. Different profiles for non-SLD control, dysgraphia, and dyslexia groups were identified in correlations between total fixation time, total number of fixations, regressions in during saccades, magnitude of gray matter connectivity during the fMRI sentence reading comprehension from left occipital temporal cortex seed with right BA44 and from left inferior frontal gyrus with right inferior frontoccipital fasciculus, and normed word-specific spelling and silent word reading fluency measures. The dysgraphia group was more likely than the non-SLD control or dyslexia groups to show negative correlations between eye movement outcomes and sentences containing incorrect homonym foils. Findings are discussed in reference to a systems approach in future sentence reading comprehension research that integrates eye movement, brain, and literacy measures.

    Directory of Open Access Journals (Sweden)

    Shahana Zabeen

    2012-06-01

    Full Text Available Background: As silent myocardial ischemia (SMI is more common in diabetic population leading to the development of future coronary artery disease (CAD, so its early diagnosis is important. SMI can be diagnosed by conventional cardiac stress testing. Presence of SMI can also be suspected by microalbuminuria (MAU because recently it is claimed that MAU is one of the important predictor for cardiovascular disease. Objective: The study was designed to explore the association between SMI & MAU in type 2 DM. Methods: It was a cross sectional study carried out in the Department of Biochemistry, BSMMU during the period of July 2006 to June 2008. One hundred diagnosed type 2 DM patients were selected from out patient department of BIRDEM. Enrolled study subjects were advised to do ETT and then categorized as ETT +ve & ETT-ve on the basis of ETT findings. Urinary micro albumin was measured in all study subjects. Unpaired t test, , chi square test, odds ratio were used to see the level of significance Results: Among the 100 type 2 diabetic subjects of both sexes 50 (male -24, female- 26 were ETT +ve designated as type 2 DM with silent MI and rest 50 ( male- 25 , female-25 were ETT –ve designated as type 2 DM without silent MI. 21 patients (42% out of 50 type 2 DM with silent MI & 16 patients (32% out of 50 type 2 DM without silent MI found to have microalbuminuria. Calculated odds ratio was 1.5. Conclusion: Microalbuminuria is a possible risk factor for SMI in type 2 DM. Urinary micro albumin can be used particularly as a screening test for early detection of SMI.DOI: http://dx.doi.org/10.3329/bsmmuj.v5i1.11016 BSMMU J 2012; 5(1:42-45

    Although we have occasionally experienced silent thrombi in the left atrium (LA), defined as thrombi free from embolic events, by screening transesophageal echocardiography (TEE) for atrial fibrillation (AF), few data are available on predictors and outcomes of silent LA thrombi in patients with AF. We retrospectively reviewed clinical records and identified 83 patients (2.6%) with silent LA thrombi, out of 4,214 TEE procedures in 3,139 patients with AF at 6 hospitals from January 2010 to December 2012. The median [interquartile range] CHA2DS2-VASc score was 3 [2, 5]. Most patients (n = 71, 86%) were taking oral anticoagulants before the TEE, and 59 patients (71%) had heart failure (HF). During follow-up periods of 905 [620, 1301] days, ischemic stroke and systemic embolism, and hemorrhagic stroke occurred only in 3 (3.6%) and 2 patients (2.4%), respectively. All-cause death developed in 14 patients (17%), and cardiac death was the primary cause of death (n = 9, 11%). Multivariate Cox regression analysis showed the composite end point of death, stroke, systemic embolism, and major bleeding was significantly associated with age (hazard ratio; 1.06, 95% confidence interval; 1.01 to 1.11, p = 0.019) and HF (3.18, 1.27 to 7.99, p = 0.014). In conclusion, the incidence of ischemic stroke after detecting silent LA thrombi was relatively low in patients with AF under oral anticoagulation. Advanced age and HF were predictors for worse outcomes in AF patients with silent LA thrombi. Copyright © 2017 Elsevier Inc. All rights reserved.

    This study introduces a reading chart application for the iPad tablet in the Korean language and investigates the reading speed in a normal-sighted population according to age group. Sixty-three Korean sentences were selected from textbooks for second grade elementary school students. A commonly used typeface in everyday printed material, "BatangChe," was used. Letter size was presented in logarithm of the minimum angle of resolution (logMAR) 0.0 to 1.0 at 0.1 logMAR steps at a reading distance of 40 cm. A third generation retina display iPad was used to present the chart, and the sentences were presented randomly for each size of letter. The subjects repeated the test silently (reading only) and out loud (reading and speaking) to prevent them from skipping reading words. Pilot testing followed in 65 normal vision adults under 60 years of age. The mean reading only speed for logMAR 0.5 optotype (point 10) was 121.1 ± 47.2 words per minute (wpm) for people in their 20s (n=21), 116.5 ± 38.3 in their 30s (n=27), 93.8 ± 12.6 in their 40s (n=9), and 56.5 ± 42.7 (n=8) in their 50s. There was a significant correlation between age and reading and speaking speed (r=-0.48, preading only speed for logMAR 0.5 optotype (point 10) was 202.3 ± 88.4 wpm and the mean reading and speaking speed was 129.7 ± 25.9 wpm, with significantly different (preading chart application could present a new standard when checking reading speed according to age groups.

    Full Text Available Reading music allows, through different processes, learnt abilities and previous experiences, for the recreation or interpretation of the musical message which had been previously coded using one of the many notation systems available. In the same way, reading music enables the experienced musician to generate musical images internally, which silently represent the coded message. The most generic processes and characteristics amongst musical reading will be analysed, along with the most common forms and applications of these reading models and the most widely used codes and notation systems. In the second part, the development and use of new tecnologies for reading music in electronic devices are described and the penetration of these tools in the musical community analysed and classified, bearing in mind the most common types and functions and the characteristics and basic functionalities of the most representative applications. Some solutions, developed in order to deal with historical problems within the reading of music, such as the turning over of the page, are also considered.

    This study's purpose was to examine the comprehension, rate and perceptions and reading preferences of adults with severe traumatic brain injury (TBI) when reading passages with and without computerized text-to-speech (TTS) support. Nine adults with severe TBI read 24 passages in two conditions: with and without TTS support. The researchers compared reading rate and comprehension accuracy across conditions. Also, participants rated their perceived performance and reading preferences via a follow-up questionnaire. Comparison to normative data revealed that all nine participants read slower than average neurotypical readers. As a group, participants read significantly faster with TTS support than without such support, even though the TTS reading rate was roughly comparable to the oral rather than silent reading rate of neurotypical adults. No significant differences in comprehension resulted between the two conditions. Over half of the participants preferred the TTS condition over the no-TTS condition. In general, participants were inaccurate in judging their relative reading rates and comprehension accuracy across conditions. TTS may improve reading efficiency without compromising reading comprehension accuracy for adults with TBI. Given this finding, some survivors may find use of TTS technology contributes to increased participation in and efficiency when performing reading activities.

  3. EMPOWERING THE READING READABILITY

    Full Text Available A general assumption about reading is that students improve their reading ability by reading a lot. This research was conducted to explain the use of extensive reading and aimed to figure out its implementation in improving students’ reading readability by using the class action research technique. The data of this research relates to the students ‘reading progress shown in their reading reports: spoken and written summary, reading comprehension and vocabulary mastery and their participation. The strategy was evolved in the continuity of reading. Students were encouraged to read extensively in and outside class. The findings indicated that the implementation could improve students’ reading readability.This attainment demonstrated that students’ reading readabilityis frosted through the continuity of reading. Other facts showed that students enjoyed reading. Students’ curiosity was also a significant factor. Their high curiosity explained why students continued reading though they realized that materials they read were difficult enough. Students’ self-confidence was also built as they were required to write a retelling story and to share their previous reading. Instead of their retelling and summarizing, students felt to be appreciated as readers. This appreciation indirectly helped students to improve the reading fondness.

    To compare eye movements during silent reading of three eBooks and a printed book. The three different eReading tools were a desktop PC, iPad tablet and Kindle eReader. Video-oculographic technology was used for recording eye movements. In the case of reading from the computer display the recordings were made by a video camera placed below the computer screen, whereas for reading from the iPad tablet, eReader and printed book the recording system was worn by the subject and had two cameras: one for recording the movement of the eyes and the other for recording the scene in front of the subject. Data analysis provided quantitative information in terms of number of fixations, their duration, and the direction of the movement, the latter to distinguish between fixations and regressions. Mean fixation duration was different only in reading from the computer display, and was similar for the Tablet, eReader and printed book. The percentage of regressions with respect to the total amount of fixations was comparable for eReading tools and the printed book. The analysis of eye movements during reading an eBook from different eReading tools suggests that subjects' reading behaviour is similar to reading from a printed book. © 2012 The College of Optometrists.

    Background Sickle cell disease (SCD) is one of the commonest severe monogenic disorders in the world, due to the inheritance of two abnormal haemoglobin (beta globin) genes. SCD can cause severe pain, significant end-organ damage, pulmonary complications, and premature death. Silent cerebral infarcts are the commonest neurological complication in children and probably adults with SCD. Silent cerebral infarcts also affect academic performance, increase cognitive deficits and may lower intelligence quotient. Objectives To assess the effectiveness of interventions to reduce or prevent silent cerebral infarcts in people with SCD. Search methods We searched for relevant trials in the Cochrane Library, MEDLINE (from 1946), Embase (from 1974), the Transfusion Evidence Library (from 1980), and ongoing trial databases; all searches current to 19 September 2016. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register: 06 October 2016. Selection criteria Randomised controlled trials comparing interventions to prevent silent cerebral infarcts in people with SCD. There were no restrictions by outcomes examined, language or publication status. Data collection and analysis We used standard Cochrane methodological procedures. Main results We included five trials (660 children or adolescents) published between 1998 and 2016. Four of the five trials were terminated early. The vast majority of participants had the haemoglobin (Hb)SS form of SCD. One trial focused on preventing silent cerebral infarcts or stroke; three trials were for primary stroke prevention and one trial dealt with secondary stroke prevention. Three trials compared the use of regular long-term red blood cell transfusions to standard care. Two of these trials included children with no previous long-term transfusions: one in children with normal transcranial doppler (TCD) velocities; and one in children with abnormal TCD velocities. The third trial included children and adolescents on

    Sporothrix schenckii (S. schenckii) is a dimorphic fungus that produces lymphocutaneous lesions. The signature characteristic of S. schenckii is a temperature-induced phase transition. Silent information regulator (Sir) has been proven to be involved in phenotypic switching in Saccharomyces cerevisiae (S. cerevisiae) and Candida albicans (C. albicans) by organizing chromatin structure. In this study, we isolated and characterized a Sir homologue gene, designated as SsSir2, from the yeast form of S. schenckii. The full-length SsSir2 cDNA sequence is 1753 bp in size and contains an open reading frame of 1329 bp encoding 442 amino acids. The predicted molecular mass of SsSir2 is 48.1 kDa with an estimated theoretical isoelectric point of 4.6. The SsSir2 kinase domain shows a 78% identity with that of Hst2, a Sir2 Ib gene from S. cerevisiae. Three exons and two introns were identified within the 1472‑bp SsSir2 genomic DNA sequence of S. schenckii. A three-dimensional model of SsSir2 was constructed using a homology modeling method, and its reliability was evaluated. The active site of SsSir2 was identified by docking simulation, which indicated that several important residues, such as Asn127 and Asp129, play an important role in the histone deacetylase activity of Sir2 family proteins. The differential expression of the SsSir2 in two stages was demonstrated by real-time RT-PCR. The expression of SsSir2 was higher in the yeast stage compared with that in the mycelial one, which indicated that SsSir2 may be involved in the phenotypic switching and morphogenesis of the yeast phase in S. schenckii.

  7. Many Neighbors are not Silent. fMRI Evidence for Global Lexical Activity in Visual Word Recognition.

    Directory of Open Access Journals (Sweden)

    Mario eBraun

    2015-07-01

    Full Text Available Many neurocognitive studies investigated the neural correlates of visual word recognition, some of which manipulated the orthographic neighborhood density of words and nonwords believed to influence the activation of orthographically similar representations in a hypothetical mental lexicon. Previous neuroimaging research failed to find evidence for such global lexical activity associated with neighborhood density. Rather, effects were interpreted to reflect semantic or domain general processing. The present fMRI study revealed effects of lexicality, orthographic neighborhood density and a lexicality by orthographic neighborhood density interaction in a silent reading task. For the first time we found greater activity for words and nonwords with a high number of neighbors. We propose that this activity in the dorsomedial prefrontal cortex reflects activation of orthographically similar codes in verbal working memory thus providing evidence for global lexical activity as the basis of the neighborhood density effect. The interaction of lexicality by neighborhood density in the ventromedial prefrontal cortex showed lower activity in response to words with a high number compared to nonwords with a high number of neighbors. In the light of these results the facilitatory effect for words and inhibitory effect for nonwords with many neighbors observed in previous studies can be understood as being due to the operation of a fast-guess mechanism for words and a temporal deadline mechanism for nonwords as predicted by models of visual word recognition. Furthermore, we propose that the lexicality effect with higher activity for words compared to nonwords in inferior parietal and middle temporal cortex reflects the operation of an identification mechanism and based on local lexico-semantic activity.

    Full Text Available The aim of this paper is to correlate the extent of silent cerebral infarcts (SCIs on magnetic resonance imaging (MRI with the clinical severity of sickle cell disease (SCD in adult patients. Twenty-four consecutive adult asymptomatic SCD patients (11 male and 13 female with a mean age of 38.4 years (range 20-59 were submitted to brain MRI on a 1 Tesla Gyroscan Intera, Philips MR scanner with a dedicated head coil. The protocol consisted of TSE T2-weighted and FLAIR images on the axial and coronal planes. MRI readings were undertaken by two radiologists and consensus readings. Patients were compound heterozygotes (HbS/β-thal. The extent of SCIs was classified from 0-2 with 0 designating no lesions. Clinical severity was graded as 0-2 by the hematologist, according to the frequency and severity of vaso-occlusive crises. There was no statistically significant correlation between the severity of clinical disease and the extent of SCIs on MR imaging. The extent of SCI lesions did not differ statistically between younger and older patients. Patients receiving hydroxyurea had no statistically significant difference in the extent of SCI lesions. The extent of SCIs in heterozygous (HbS/β-thal SCD patients is not age related and may be quite severe even in younger (<38.4 years patients. However the extent of SCIs is not correlated with the severity of clinical disease.

  14. Reading charts in ophthalmology.

    2017-08-01

    A new generation of logarithmic reading charts has sparked interest in standardized reading performance analyses. Such reading charts have been developed according to the standards of the International Council of Ophthalmology. The print size progression in these calibrated charts is in accordance with the mathematical background of EN ISO 8596. These reading charts are: the Bailey-Lovie Word Reading Chart, the Colenbrander English Continuous Text Near Vision Cards, the Oculus Reading Probe II, the MNREAD Charts, the SKread Charts, and the RADNER Reading Charts. The test items used for these reading charts differ among the charts and are standardized to various extents. The Bailey-Lovie Charts, MNREAD Charts, SKread Charts, and RADNER Charts are also meant to measure reading speed and allow determination of further reading parameters such as reading acuity, reading speed based on reading acuity, critical print size, reading score, and logMAR/logRAD ratio. Such calibrated reading charts have already provided valuable insights into the reading performance of patients in many research studies. They are available in many languages and thus facilitate international communication about near visual performance. In the present review article, the backgrounds of these modern reading charts are presented, and their different levels of test-item standardization are discussed. Clinical research studies are mentioned, and a discussion about the immoderately high number of reading acuity notations is included. Using the logReading Acuity Determination ([logRAD] = reading acuity equivalent of logMAR) measure for research purposes would give reading acuity its own identity as a standardized reading parameter in ophthalmology.

    2012-12-01

    Drawing upon archival and published sources, 'Like a Keen North Wind,' suggests that Charles Elton's book-The Ecology of Invasions by Animals and Plants-served to galvanize Rachel Carson's ideas while she was writing Silent Spring. Carson had already amassed numerous cases of the poisoning of the environment and wildlife as well as humans. Elton's book helped Carson to draw connections between the various kinds of exposures. Yet, it was Carson's genius to animate Silent Spring with vivid examples that captivated her readers and convinced them to question indiscriminate use of pesticides. Moreover, Carson adroitly bridged the growing divide between scientists and the public. Copyright © 2012 Elsevier Ltd. All rights reserved.

    2002-01-01

    Forty years ago, in the enormously praised and fiercely criticized book, "Silent Spring", Rachel Carson demonstrated the dangers of pesticides to humans and ecosystems and called for precaution in their use. Yet, the majority of environmental regulations passed since 1962 have primarily addressed pollutant discharge rather than cleaner products and technologies. The number of active ingredients in pesticides used in the United States has risen from 32 in 1939 to 860 in recent times, while the overall volume of agrochemicals applied has nearly doubled since the publication of Silent Spring. The last 40 years have brought significant changes with respect to environmental policies, agricultural technologies, urbanization, civil rights, women's rights, the roles of non-profit organizations and community development, and increased poverty, hunger, and economic inequality. In recent years, new voices, new analyses, and new movements have emerged offering fresh perspectives on how we can answer Carson's clarion call to protect our planet and ourselves.

    Akila Theyyar Rajappa

    2017-08-01

    Full Text Available Background and purposePreliminary evidence has shown that reduced ability to maximally raise vocal pitch correlates with the occurrence of aspiration (i.e., airway invasion by food or liquid. However, it is unclear if this simple task can be used as a reliable predictor of aspiration in stroke patients. Our aim was to examine whether maximum vocal pitch elevation predicted airway invasion and dysphagia in stroke.MethodsForty-five consecutive stroke patients (<1 month poststroke at a rehabilitation setting participated in a videofluoroscopic swallow study and two maximum vocal pitch elevation tasks. Maximum pitch was evaluated acoustically [maximum fundamental frequency (max F0] and perceptually. Swallowing safety was rated using the Penetration/Aspiration Scale and swallowing performance was assessed using components of the Modified Barium Swallow Impairment Profile (MBSImPTM©. Data were analyzed using simple regression and receiver operating characteristics curves to test the sensitivity and specificity of max F0 in predicting aspiration. Correlations between max F0 and MBSImP variables were also examined.ResultsMax F0 predicted silent aspiration of small liquid volumes with 80% sensitivity and 65% specificity (p = 0.023; area under the curve: 0.815; cutoff value of 359.03 Hz. Max F0 did not predict non-silent aspiration or penetration in this sample and did not significantly correlate with MBSImP variables. Furthermore, all participants who aspirated silently on small liquid volumes (11% of sample had suffered cortical or subcortical lesions.ConclusionIn stroke patients (<1 month poststroke, reduced maximum pitch elevation predicts silent aspiration of small liquid volumes with high sensitivity and moderate specificity. Future large-scale studies focusing on further validating this finding and exploring the value of this simple and non-invasive tool as part of a dysphagia screening are warranted.

    Children with sickle cell anemia have a higher-than-expected prevalence of poor educational attainment. We test two key hypotheses about educational attainment among students with sickle cell anemia, as measured by grade retention and use of special education services: (1) lower household per capita income is associated with lower educational attainment; (2) the presence of a silent cerebral infarct is associated with lower educational attainment. We conducted a multicenter, cross-sectional study of cases from 22 U.S. sites included in the Silent Infarct Transfusion Trial. During screening, parents completed a questionnaire that included sociodemographic information and details of their child’s academic status. Of 835 students, 670 were evaluable; 536 had data on all covariates and were used for analysis. The students’ mean age was 9.4 years (range: 5–15) with 52.2% male; 17.5% of students were retained one grade level and 18.3% received special education services. A multiple variable logistic regression model identified that lower household per capita income (odds ratio [OR] of quartile 1 = 6.36, OR of quartile 2 = 4.7, OR of quartile 3 = 3.87; P = 0.001 for linear trend), age (OR = 1.3; P sickle cell anemia, household per capita income is associated with grade retention, whereas the presence of a silent cerebral infarct is not. Future educational interventions will need to address both the medical and socioeconomic issues that affect students with sickle cell anemia. PMID:25042018

    Aging is associated with declines in executive function. We examined how executive functional brain systems are influenced by clinically silent Alzheimer's disease (AD) pathology and cerebral white-matter hyperintensities (WMHs). Twenty-nine younger adults and 34 cognitively normal older adults completed a working memory paradigm while functional magnetic resonance imaging was performed. Older adults further underwent lumbar cerebrospinal fluid draw for the assessment of AD pathology and FLAIR imaging for the assessment of WMHs. Accurate working memory performance in both age groups was associated with high fronto-visual functional connectivity (fC). However, in older adults, higher expression of fronto-visual fC was linked with lower levels of clinically silent AD pathology. In addition, AD pathology and WMHs were each independently related to increased functional magnetic resonance imaging response in the left dorsolateral prefrontal cortex, a pattern associated with slower task performance. Our results suggest that clinically silent AD pathology is related to lower expression of a fronto-visual fC pattern supporting executive task performance. Further, our findings suggest that AD pathology and WMHs appear to be linked with ineffective increases in frontal response in CN older adults. Copyright © 2017 Elsevier Inc. All rights reserved.

  4. Petrologic evolution of divergent peralkaline magmas from the Silent Canyon caldera complex, southwestern Nevada volcanic field

    Science.gov (United States)

    Sawyer, D.A.; Sargent, K.A.

    1989-01-01

    The Silent Canyon volcanic center consists of a buried Miocene peralkaline caldera complex and outlying peralkaline lava domes. Two widespread ash flow sheets, the Tub Spring and overlying Grouse Canyon members of the Miocene Belted Range Tuff, were erupted from the caldera complex and have volumes of 60-100 km3 and 200 km3, respectively. Eruption of the ash flows was preceded by widespread extrusion of precaldera comendite domes and was followed by extrusion of postcollapse peralkaline lavas and tuffs within and outside the caldera complex. Lava flows and tuffs were also deposited between the two major ash flow sheets. Rocks of the Silent Canyon center vary significantly in silica content and peralkalinity. Weakly peralkaline silicic comendites (PI 1.0-1.1) are the most abundant precaldera lavas. Postcollapse lavas range from trachyte to silicic comendite; some have anomalous light rare earth element (LREE) enrichments. Silent Canyon rocks follow a common petrologic evolution from trachyte to low-silica comendite; above 73% SiO2, compositions of the moderately peralkaline comendites diverge from those of the weakly peralkaline silicic comendites. The development of divergent peralkaline magmas, toward both pantelleritic and weakly peralkaline compositions, is unusual in a single volcanic center. -from Authors

    Supercomputers allow scientists to study natural phenomena by means of computer simulations. Next-generation machines are expected to have more components and, at the same time, consume several times less energy per operation. These trends are pushing supercomputer construction to the limits of miniaturization and energy-saving strategies. Consequently, the number of soft errors is expected to increase dramatically in the coming years. While mechanisms are in place to correct or at least detect some soft errors, a significant percentage of those errors pass unnoticed by the hardware. Such silent errors are extremely damaging because they can make applications silently produce wrong results. In this work we propose a technique that leverages certain properties of high-performance computing applications in order to detect silent errors at the application level. Our technique detects corruption solely based on the behavior of the application datasets and is completely application-agnostic. We propose multiple corruption detectors, and we couple them to work together in a fashion transparent to the user. We demonstrate that this strategy can detect the majority of the corruptions, while incurring negligible overhead. We show that with the help of these detectors, applications can have up to 80% of coverage against data corruption.

  6. Silent and a audible stereotypes: The constitution of "ethnic character" in Serbian epic poetry

    Full Text Available The article deals with the explanatory relevance of the concept of stereotype in one of its original meanings - as a "mental image". This meaning of the term is the starting point for further differentiations, such as: between linguistic and behavioral stereotypes (in the sense of nonverbal, expected responses; universal and particular stereotypes; self representative and introspective stereotypes; permanent and contemporary stereotypes; and finally, what is most important for our purposes, the difference between silent and audible stereotypes. These distinctions, along with the functions of stereotype, are discussed in the first part of the paper. In the second part, the relations of silent and audible stereotypes are tested against the introduction of "innovative vocabularies" in popular lore. In other words, the explanatory power of this differentiation is checked through an analysis of unconventional motives in Serbian epic poems. The goal of the argument is to clarify the procedure of self creation of masculinity as a relevant feature of the "national character" through "tactic games" of silent and audible stereotypes. The examination of these "poetic strategies" serves a twofold purpose: to illustrate the process of constructing particular features of the "ethno type", on one hand, and to check hypotheses and models which are taken as frameworks in analyzing stereotypes, on the other.

    Developing networks in the immature nervous system and in cellular cultures are characterized by waves of synchronous activity in restricted clusters of cells. Synchronized activity in immature networks is proposed to regulate many different developmental processes, from neuron growth and cell migration, to the refinement of synapses, topographic maps, and the mature composition of ion channels. These emergent activity patterns are not present in all cells simultaneously within the network and more immature "silent" cells, potentially correlated with the presence of silent synapses, are prominent in different networks during early developmental periods. Many current network analyses for detection of synchronous cellular activity utilize activity-based pixel correlations to identify cellular-based regions of interest (ROIs) and coincident cell activity. However, using activity-based correlations, these methods first underestimate or ignore the inactive silent cells within the developing network and second, are difficult to apply within cell-dense regions commonly found in developing brain networks. In addition, previous methods may ignore ROIs within a network that shows transient activity patterns comprising both inactive and active periods. We developed analysis software to semi-automatically detect cells within developing neuronal networks that were imaged using calcium-sensitive reporter dyes. Using an iterative threshold, modulation of activity was tracked within individual cells across the network. The distribution pattern of both inactive and active, including synchronous cells, could be determined based on distance measures to neighboring cells and according to different anatomical layers. © 2015 Wiley Periodicals, Inc.

    Purpose Incidental reading provides a powerful opportunity for partial word knowledge growth in the school-age years. The extent to which children of differing language abilities can use reading experiences to glean partial knowledge of words is not well understood. The purpose of this study was to compare semantic–syntactic partial word knowledge growth of children with higher language skills (HL group; overall language standard scores of 85 or higher) to that of children with relatively lower language skills (LL group; overall receptive or expressive standard score below 85). Method Thirty-two children, 16 per group, silently read stories containing unfamiliar nouns and verbs 3 times over a 1-week period. Semantic–syntactic partial word knowledge growth was assessed after each reading and 2–3 days later to assess retention. Results Over time, both groups showed significant partial word knowledge growth, with the HL group showing significantly more growth. In addition, both groups retained knowledge several days later. Conclusion Regardless of language skill level, children benefit from multiple exposures to unfamiliar words in reading in their development and retention of semantic–syntactic partial word knowledge growth.

  11. The Relation between Reading Skills and Eye Movement Patterns in Adolescent Readers: Evidence from a Regular Orthography.

    Full Text Available Over the past decades, the relation between reading skills and eye movement behavior has been well documented in English-speaking cohorts. As English and German differ substantially with regard to orthographic complexity (i.e. grapheme-phoneme correspondence, we aimed to delineate specific characteristics of how reading speed and reading comprehension interact with eye movements in typically developing German-speaking (Austrian adolescents. Eye movements of 22 participants (14 females; mean age = 13;6 years;months were tracked while they were performing three tasks, namely silently reading words, texts, and pseudowords. Their reading skills were determined by means of a standardized German reading speed and reading comprehension assessment (Lesegeschwindigkeits- und -verständnistest für Klassen 6-12. We found that (a reading skills were associated with various eye movement parameters in each of the three reading tasks; (b better reading skills were associated with an increased efficiency of eye movements, but were primarily linked to spatial reading parameters, such as the number of fixations per word, the total number of saccades and saccadic amplitudes; (c reading speed was a more reliable predictor for eye movement parameters than reading comprehension; (d eye movements were highly correlated across reading tasks, which indicates consistent reading performances. Contrary to findings in English-speaking cohorts, the reading skills neither consistently correlated with temporal eye movement parameters nor with the number or percentage of regressions made while performing any of the three reading tasks. These results indicate that, although reading skills are associated with eye movement patterns irrespective of language, the temporal and spatial characteristics of this association may vary with orthographic consistency.

    Although eye movements during reading are modulated by cognitive processing demands, they also reflect visual sampling of the input, and possibly preparation of output for speech or the inner voice. By simultaneously recording eye movements and the voice during reading aloud, we obtained an output measure that constrains the length of time spent on cognitive processing. Here we investigate the dynamics of the eye-voice span (EVS), the distance between eye and voice. We show that the EVS is regulated immediately during fixation of a word by either increasing fixation duration or programming a regressive eye movement against the reading direction. EVS size at the beginning of a fixation was positively correlated with the likelihood of regressions and refixations. Regression probability was further increased if the EVS was still large at the end of a fixation: if adjustment of fixation duration did not sufficiently reduce the EVS during a fixation, then a regression rather than a refixation followed with high probability. We further show that the EVS can help understand cognitive influences on fixation duration during reading: in mixed model analyses, the EVS was a stronger predictor of fixation durations than either word frequency or word length. The EVS modulated the influence of several other predictors on single fixation durations (SFDs). For example, word-N frequency effects were larger with a large EVS, especially when word N-1 frequency was low. Finally, a comparison of SFDs during oral and silent reading showed that reading is governed by similar principles in both reading modes, although EVS maintenance and articulatory processing also cause some differences. In summary, the EVS is regulated by adjusting fixation duration and/or by programming a regressive eye movement when the EVS gets too large. Overall, the EVS appears to be directly related to updating of the working memory buffer during reading.

    Processing-speed deficits affect reading efficiency, even among individuals who recognize and decode words accurately. Children with ADHD who decode words accurately can still have inefficient reading fluency, leading to a bottleneck in other cognitive processes. This "slowing" in ADHD is associated with deficits in fundamental components of executive function underlying processing speed, including response selection. The purpose of the present study was to deconstruct processing speed in order to determine which components of executive control best explain the "processing" speed deficits related to reading fluency in ADHD. Participants (41 ADHD, 21 controls), ages 9-14 years, screened for language disorders, word reading deficits, and psychiatric disorders, were administered measures of copying speed, processing speed, reading fluency, working memory, reaction time, inhibition, and auditory attention span. Compared to controls, children with ADHD showed reduced oral and silent reading fluency and reduced processing speed-driven primarily by deficits on WISC-IV Coding. In contrast, groups did not differ on copying speed. After controlling for copying speed, sex, severity of ADHD-related symptomatology, and GAI, slowed "processing" speed (i.e., Coding) was significantly associated with verbal span and measures of working memory but not with measures of response control/inhibition, lexical retrieval speed, reaction time, or intrasubject variability. Further, "processing" speed (i.e., Coding, residualized for copying speed) and working memory were significant predictors of oral reading fluency. Abnormalities in working memory and response selection (which are frontally mediated and enter into the output side of processing speed) may play an important role in deficits in reading fluency in ADHD, potentially more than posteriorally mediated problems with orienting of attention or perceiving the stimulus.

    To investigate the capacity for self-monitoring reading comprehension in Brazilian Elementary School students. Fifty-three Elementary students in the 5th and 9th grades from two Public Schools in the city of São Paulo were assessed. They were selected based on their oral reading rate and grouped according to their performance in reading comprehension in the following categories: Group with best comprehension: students with adequate rate and accuracy, without difficulties in reading comprehension; Group with worst comprehension: students with adequate rate and accuracy but with difficulties in reading comprehension. Two narrative texts followed by eight questions to assess reading comprehension were presented. Two sentences and two words were replaced by ungrammatical elements and pseudo-words. Under the condition of spontaneous monitoring, students read the text aloud and answered the questions. The analysis considered the calculation of hesitation, self-correction, repetitions and mistakes. Under the condition of directed monitoring, students were instructed to read the text, either aloud or silently, after being told that certain parts of the text could not make sense, and they were oriented to underline such parts. The analysis was carried out by counting of underlined items. The comparisons were made with the Mann-Whitney test. A difference was observed between the groups only at the sentence level among the 9th grade schoolchildren under the spontaneous monitoring and among the 5th grade schoolchildren under directed monitoring. Students with worst comprehension had a poorer performance to monitor the presence of ungrammatical sentences than their peers with best comprehension.

    We investigated the prevalence and characteristics of ischemic heart disease especially silent myocardial ischemia (SMI) and arrhythmia in need of careful observation in the exercise stress tests in the Total Health Promotion Plan (THP), which was conducted between 1994-96 for the purpose of measuring cardiopulmonary function. All workers (n = 4,918, 4,426 males) aged 18-60 yr old in an occupational field were studied. Exercise tests with an ergometer were performed by the LOPS protocol, in which the maximal workload was set up as a presumed 70-80% maximal oxygen intake, or STEP (original multistage protocol). ECG changes were evaluated with a CC5 lead. Two hundred and fifteen people refused the study because of a common cold, lumbago and so on. Of 4,703 subjects, 17 with abnormal rest ECG and 19 with probable anginal pain were excluded from the exercise tests. Of 4,667 who underwent the exercise test, 37 (0.79%) had ischemic ECG change, and 155 (3.32%) had striking arrhythmia. These 228 subjects then did a treadmill exercise test with Bruce protocol. Twenty-two (0.47% of 4,703) showed positive ECG change, 9 (0.19%) of 22 had abnormal findings on a 201Tl scan. 8 (0.17%) were diagnosed as SMI (Cohn I), in which the prevalence of hypertension, hyperlipidemia, diabetes mellitus, smoker and positive familial history of ischemic heart disease was greater than that of all subjects. In a 15-30 month follow up, none has developed cardiac accidents. Exercise-induced arrhythmia was detected in 11 (0.23%) subjects. Four were non-sustained ventricular tachycardia without any organic disease, 4 were ventricular arrhythmia based on cardiomyopathy detected by echocardiography, 2 were atrial fibrillation and another was WPW syndrome. It is therefore likely that the ergometer exercise test in THP was effective in preventing sudden death caused by ischemic heart disease or striking arrhythmia.

    To identify effective treatment for both the spelling and word decoding problems in dyslexia, 24 students with dyslexia in grades 4 to 9 were randomly assigned to treatments A (n=12) or B (n=12) in an after-school reading-writers' workshop at the university (thirty 1-h sessions twice a week over 5 months). First, both groups received step 1 treatment of grapheme-phoneme correspondences (gpc) for oral reading. At step 2, treatment A received gpc training for both oral reading and spelling, and treatment B received gpc training for oral reading and phonological awareness. At step 3, treatment A received orthographic spelling strategy and rapid accelerated reading program (RAP) training, and treatment B continued step 2 training. At step 4, treatment A received morphological strategies and RAP training, and treatment B received orthographic spelling strategy training. Each treatment also had the same integrated reading-writing activities, which many school assignments require. Both groups improved significantly in automatic letter writing, spelling real words, compositional fluency, and oral reading (decoding) rate. Treatment A significantly outperformed treatment B in decoding rate after step 3 orthographic training, which in turn uniquely predicted spelling real words. Letter processing rate increased during step 3 RAP training and correlated significantly with two silent reading fluency measures. Adding orthographic strategies with "working memory in mind" to phonics helps students with dyslexia spell and read English words.

    2007-01-01

    Full Text Available This paper discusses possible contributions of psychologists to sustainable transportation. It is argued that in order to reach sustainable transportation, among others, behaviour changes of individual car users are needed. As transport policies will be more effective if they target important antecedents of travel behaviour, first, factors influencing such behaviour are discussed. It is argued that car use is very attractive and sometimes even necessary for many different reasons. This implies that a combination of policies is called for, each targeting different factors that support car use and hinder the use of more sustainable modes of transport. Next, the paper elaborates on policy strategies that may be employed to achieve sustainable transportation by changing car use. Increasing the attractiveness of sustainable transport modes by means of pull measures seems not sufficient to reduce the level of car use. Besides, car use should be made less attractive by means of push measures to force drivers to reconsider their travel behaviour. The acceptability of such policies may be increased by clearly communicating the aim of these policies, and the expected positive consequences (e.g., less congestion, improved environmental quality. Moreover, possible negative effects for individual freedom may be compensated by implementing additional policies aimed at facilitating the use of sustainable transport modes.

    In reading aloud, the eye typically leads over voice position. In the present study, eye movements and voice utterances were simultaneously recorded and tracked during the reading of a meaningful text to evaluate the eye-voice lead in 16 dyslexic and 16 same-age control readers. Dyslexic children were slower than control peers in reading texts. Their slowness was characterized by a great number of silent pauses and sounding-out behaviors and a small lengthening of word articulation times. Regarding eye movements, dyslexic readers made many more eye fixations (and generally smaller rightward saccades) than controls. Eye movements and voice (which were shifted in time because of the eye-voice lead) were synchronized in dyslexic readers as well as controls. As expected, the eye-voice lead was significantly smaller in dyslexic than control readers, confirming early observations by Buswell (1921) and Fairbanks (1937). The eye-voice lead was significantly correlated with several eye movements and voice parameters, particularly number of fixations and silent pauses. The difference in performance between dyslexic and control readers across several eye and voice parameters was expressed by a ratio of about 2. We propose that referring to proportional differences allows for a parsimonious interpretation of the reading deficit in terms of a single deficit in word decoding. The possible source of this deficit may call for visual or phonological mechanisms, including Goswami's temporal sampling framework. PMID:24223541

    Full Text Available Objetivos: determinar la frecuencia de isquemia miocárdica silente en diabéticos tipo 2 y su relación con el control metabólico. Métodos: se realizó un estudio descriptivo transversal en 79 pacientes asintomáticos con diabetes mellitus tipo 2 sin antecedentes de cardiopatía isquémica, hipertensión arterial o de ser fumador, que acudieron a la Consulta de Endocrinología del Hospital Militar Central "Dr. Carlos J. Finlay", entre febrero de 2009 y febrero de 2011. Se les realizó ecocardiografía con doppler tisular y se determinaron los niveles de glucemia en ayunas, posprandial, hemoglobina glucosilada, colesterol y triglicéridos. Las variables clínicas analizadas en relación con la isquemia miocárdica silente fueron: edad, sexo, tiempo de evolución de la diabetes e índice de masa corporal. Para las variables cualitativas se utilizaron distribuciones de frecuencia con el cálculo del porcentaje y para establecer relación entre variables la prueba de chi cuadrado. Resultados: la edad media del total de pacientes fue de 54 años, de ellos el 69,1 % correspondió al sexo masculino y el 31,9 % al femenino. En el 20,2 % de los pacientes se observaron signos de isquemia miocárdica por doppler tisular, y de ellos, un 75 % tuvo niveles patológicos de colesterol total, con relación estadísticamente significativa (p= 0,01, sujetos que tuvieron 4,4 veces más riesgo relativo de presentar isquemia miocárdica, que los pacientes con colesterol normal. Las cifras de glucemia en ayunas, posprandial y hemoglobina glucosilada fueron significativamente mayor en el grupo con isquemia.

  12. Why read Fairbairn?

    Ogden, Thomas H

    2010-02-01

    The author offers a close reading of portions of Fairbairn's work in which he not only explicates and clarifies Fairbairn's thinking, but generates ideas of his own by developing concepts that he believes to be implicit in, or logical extensions of, Fairbairn's work. Among the unstated or underdeveloped aspects of Fairbairn's contribution that the author discusses are (1) the idea that the formation of the internal object world is always, in part, a response to trauma (actual failure on the part of the mother to convey to her infant a sense that she loves him and accepts his love); (2) the notion that the infant's unceasing efforts to transform the internalized relationship with the unloving mother into a loving relationship--thus reversing the effect on his mother of his (imagined) 'toxic love'--is the single most important motivation sustaining the structure of the internal object world; and (3) the idea that attacks on oneself for the way one loves, while self-destructive, contain a glimmer of insight into one's own self-hatred and shame regarding one's endless, futile attempts to change oneself (or the rejecting object) into a different person. The author, using his own clinical work, illustrates the way he makes use of his understanding of the 'emotional life' of internal objects to facilitate the patient's emotional growth.

    Previous studies show slow reading in strabismic amblyopia. We recently identified amblyopia, not strabismus, as the key factor in slow reading in children. No studies have focused on reading in amblyopic children without strabismus. We examined reading in anisometropic children and evaluated whether slow reading was associated with ocular motor dysfunction in children with amblyopia. Anisometropic children (7-12 years) with or without amblyopia were compared to age-similar normal controls. Children silently read a grade-appropriate paragraph during binocular viewing. Reading rate (words/min), number of forward and regressive saccades (per 100 words) and fixation duration were recorded with the ReadAlyzer. Binocular fixation instability was also evaluated (EyeLink 1000). Amblyopic anisometropic children read more slowly (n = 25; mean with standard deviation, 149 ± 42 words/min) than nonamblyopic anisometropic children (n = 15; 196 ± 80 words/min; P = 0.024) and controls (n = 25; 191 ± 65 words/min; P = 0.020). Nonamblyopic anisometropic children read at a comparable rate to controls (P = 0.81). Slow reading in amblyopic anisometropic children was correlated with increased forward saccades (r = -0.84, P saccades (r = -0.85, P reading in school-age children with anisometropic amblyopia is related to increased frequency of saccades and fixation instability of the fellow eye.

  17. Roundtabling Sustainability

    DEFF Research Database (Denmark)

    2014-01-01

    The willingness of public authority to delegate social and environmental regulation to the private sector has varied from sector to sector, but has often led to the establishment of ‘voluntary’ standards and certifications on sustainability. Many of these have taken the form of ‘stewardship...... councils’ and ‘sustainability roundtables’ and have been designed around a set of institutional features seeking to establish legitimacy, fend off possible criticism, and ‘sell’ certifications to potential users. The concept of ‘roundtabling’ emphasizes the fitting a variety of commodity......-specific sustainability situations into a form that not only ‘hears more voices’ (as in ‘multi-stakeholder’), but also portrays to give them equal standing at the table of negotiations (roundtable), thus raising higher expectations on accountability, transparency and inclusiveness. In this article, I examine to what...

    2017-03-17

    The long-term substitution of fossil resources can only be achieved through a bio-based economy, with biorefineries and bio-based products playing a major role. However, it is important to assess the implications of the transition to a bio-based economy. Life cycle-based sustainability assessment is probably the most suitable approach to quantify impacts and to identify trade-offs at multiple levels. The extended utilisation of biomass can cause land use change and affect food security of the most vulnerable people throughout the world. Although this is mainly a political issue and governments should be responsible, the responsibility is shifted to companies producing biofuels and other bio-based products. Organic wastes and lignocellulosic biomass are considered to be the preferred feedstock for the production of bio-based products. However, it is unlikely that a bio-based economy can rely only on organic wastes and lignocellulosic biomass.It is crucial to identify potential problems related to socio-economic and environmental issues. Currently there are many approaches to the sustainability of bio-based products, both quantitative and qualitative. However, results of different calculation methods are not necessarily comparable and can cause confusion among decision-makers, stakeholders and the public.Hence, a harmonised, globally agreed approach would be the best solution to secure sustainable biomass/biofuels/bio-based chemicals production and trade, and to avoid indirect effects (e.g. indirect land use change). However, there is still a long way to go.Generally, the selection of suitable indicators that serve the purpose of sustainability assessment is very context-specific. Therefore, it is recommended to use a flexible and modular approach that can be adapted to various purposes. A conceptual model for the selection of sustainability indicators is provided that facilitates identifying suitable sustainability indicators based on relevance and significance in a

    Full Text Available Abstract Background The availability of oxygen is a limiting factor for neuronal survival since low levels account not only for the impairment of physiological activities such as sleep-wake cycle, but above all for ischemic-like neurodegenerative disorders. In an attempt to improve our knowledge concerning the type of molecular mechanisms operating during stressful states like those of hypoxic conditions, attention was focused on eventual transcriptional alterations of some key AMPAergic silent neuronal receptor subtypes (GluR1 and GluR2 along with HSPs and HIF-1α during either a normoxic or a hypoxic aestivation of a typical aquatic aestivator, i.e. the lungfish (Protopterus annectens. Results The identification of partial nucleotide fragments codifying for both AMPA receptor subtypes in Protopterus annectens displayed a putative high degree of similarity to that of not only fish but also to those of amphibians, birds and mammals. qPCR and in situ hybridization supplied a very high (p p  Conclusions The distinct transcriptional variations of silent neurons expressing GluR1/2 and HSPs tend to corroborate these factors as determining elements for the physiological success of normoxic and hypoxic aestivation. A distinct switching among these AMPA receptor subtypes during aestivation highlights new potential adaptive strategies operating in key brain regions of the lungfish in relation to oxygen availability. This functional relationship might have therapeutic bearings for hypoxia-related dysfunctions, above all in view of recently identified silent neuron-dependent motor activity ameliorations in mammals.

    A small number of population-based studies reported an association between migraine with aura and risk of silent brain infarcts and white matter hyperintensities in females. We investigated these relations in a population-based sample of female twins. We contacted female twins ages 30-60 years identified through the population-based Danish Twin Registry. Based on questionnaire responses, twins were invited to participate in a telephone-based interview conducted by physicians. Headache diagnoses were established according to the International Headache Society criteria. Cases with migraine with aura, their co-twins, and unrelated migraine-free twins (controls) were invited to a brain magnetic resonance imaging scan performed at a single centre. Brain scans were assessed for the presence of infarcts, and white matter hyperintensities (visual rating scales and volumetric analyses) blinded to headache diagnoses. Comparisons were based on 172 cases, 34 co-twins, and 139 control subjects. Compared with control subjects, cases did not differ with regard to frequency of silent brain infarcts (four cases versus one control), periventricular white matter hyperintensity scores [adjusted mean difference (95% confidence interval): -0.1 (-0.5 to 0.2)] or deep white matter hyperintensity scores [adjusted mean difference (95% confidence interval): 0.1 (-0.8 to 1.1)] assessed by Scheltens' scale. Cases had a slightly higher total white matter hyperintensity volume compared with controls [adjusted mean difference (95% confidence interval): 0.17 (-0.08 to 0.41) cm(3)] and a similar difference was present in analyses restricted to twin pairs discordant for migraine with aura [adjusted mean difference 0.21 (-0.20 to 0.63)], but these differences did not reach statistical significance. We found no evidence of an association between silent brain infarcts, white matter hyperintensities, and migraine with aura. © The Author (2016).

    Learned associations between environmental stimuli and rewards play a critical role in addiction. Associative learning requires alterations in sparsely distributed populations of strongly activated neurons, or neuronal ensembles. Until recently, assessment of functional alterations underlying learned behavior was restricted to global neuroadaptations in a particular brain area or cell type, rendering it impossible to identify neuronal ensembles critically involved in learned behavior. We used Fos-GFP transgenic mice that contained a transgene with a Fos promoter driving expression of green fluorescent protein (GFP) to detect neurons that were strongly activated during associative learning, in this case, context-independent and context-specific cocaine-induced locomotor sensitization. Whole-cell electrophysiological recordings were used to assess synaptic alterations in specifically activated GFP-positive (GFP+) neurons compared with surrounding nonactivated GFP-negative (GFP-) neurons 90 min after the sensitized locomotor response. After context-independent cocaine sensitization, cocaine-induced locomotion was equally sensitized by repeated cocaine injections in two different sensitization contexts. Correspondingly, silent synapses in these mice were induced in GFP+ neurons, but not GFP- neurons, after sensitization in both of these contexts. After context-specific cocaine sensitization, cocaine-induced locomotion was sensitized exclusively in mice trained and tested in the same context (paired group), but not in mice that were trained in one context and then tested in a different context (unpaired group). Silent synapses increased in GFP+ neurons, but not in GFP- neurons from mice in the paired group, but not from mice in the unpaired group. Our results indicate that silent synapses are formed only in neuronal ensembles of the nucleus accumbens shell that are related to associative learning. Published by Elsevier Inc.

  2. Listening to the sound of silence: disfluent silent pauses in speech have consequences for listeners.

    2010-12-01

    Silent pauses are a common form of disfluency in speech yet little attention has been paid to them in the psycholinguistic literature. The present paper investigates the consequences of such silences for listeners, using an Event-Related Potential (ERP) paradigm. Participants heard utterances ending in predictable or unpredictable words, some of which included a disfluent silence before the target. In common with previous findings using er disfluencies, the N400 difference between predictable and unpredictable words was attenuated for the utterances that included silent pauses, suggesting a reduction in the relative processing benefit for predictable words. An earlier relative negativity, topographically distinct from the N400 effect and identifiable as a Phonological Mismatch Negativity (PMN), was found for fluent utterances only. This suggests that only in the fluent condition did participants perceive the phonology of unpredictable words to mismatch with their expectations. By contrast, for disfluent utterances only, unpredictable words gave rise to a late left frontal positivity, an effect previously observed following ers and disfluent repetitions. We suggest that this effect reflects the engagement of working memory processes that occurs when fluent speech is resumed. Using a surprise recognition memory test, we also show that listeners were more likely to recognise words which had been encountered after silent pauses, demonstrating that silence affects not only the process of language comprehension but also its eventual outcome. We argue that, from a listener's perspective, one critical feature of disfluency is the temporal delay which it adds to the speech signal. Copyright © 2010 Elsevier Ltd. All rights reserved.

  3. [A scientific reading method].

    1999-09-01

    To provide high quality services, nursing professionals must be prepared to update their knowledge constantly. To achieve this, various methods are available such as courses, conferences and research projects. All of these methods share one essential intellectual activity, scientific reading. Scientific reading is a complex and demanding activity that requires more than basic reading skills. Many nurses find it boring and arduous, probably because it gives them no pleasure, but especially because they lack a method. In this article, the author proposes a scientific reading method consisting of three stages: an overview approach to the text, a superficial reading, and an in-depth reading of the text. This method is simple, easy to use, and entirely appropriate for scientific reading. The author hopes that this method will give more nurses the desire to read and use scientific literature in the practice of their profession.

    To our knowledge, studies comparing binocular eye movements during reading task in strabismic children are scarce. The goal of our study was to examine binocular coordination of saccades during reading in strabismic children. Binocular eye movements were recorded by an infrared system (mobile EBT) in 18 strabismic children 6.8 to 16 years old (mean age 10.2 ± 3) who were asked to read a four-line text silently during binocular viewing. Data were compared to that of 18 age-matched non-strabismic control children. Saccade amplitude was similar in strabismic and control children. In contrast, binocular coordination during and after the saccades was significantly poorer in strabismic children as opposed to control children. The duration of fixation also was significantly longer in strabismic children compared to controls. Binocular coordination in strabismic children who have binocular vision was better than those without binocular vision, but it still was worse than in control subjects. In strabismic children binocular saccade coordination is deficient and could be responsible for impaired reading capabilities. Binocular vision has an important role in improving binocular saccade yoking.

    Phonetic detail and lateralization of inner speech during covert sentence reading as well as overt reading in 32 right-handed healthy participants undergoing 3T fMRI were investigated. The number of voiceless and voiced consonants in the processed sentences was systematically varied. Participants listened to sentences, read them covertly, silently mouthed them while reading, and read them overtly. Condition comparisons allowed for the study of effects of externally versus self-generated auditory input and of somatosensory feedback related to or independent of voicing. In every condition, increased voicing modulated bilateral voice-selective regions in the superior temporal sulcus without any lateralization. The enhanced temporal modulation and/or higher spectral frequencies of sentences rich in voiceless consonants induced left-lateralized activation of phonological regions in the posterior temporal lobe, regardless of condition. These results provide evidence that inner speech during reading codes detail as fine as consonant voicing. Our findings suggest that the fronto-temporal internal loops underlying inner speech target different temporal regions. These regions differ in their sensitivity to inner or overt acoustic speech features. More slowly varying acoustic parameters are represented more anteriorly and bilaterally in the temporal lobe while quickly changing acoustic features are processed in more posterior left temporal cortices. Furthermore, processing of external auditory feedback during overt sentence reading was sensitive to consonant voicing only in the left superior temporal cortex. Voicing did not modulate left-lateralized processing of somatosensory feedback during articulation or bilateral motor processing. This suggests voicing is primarily monitored in the auditory rather than in the somatosensory feedback channel.

  11. A Practical Strategy to Discover New Antitumor Compounds by Activating Silent Metabolite Production in Fungi by Diethyl Sulphate Mutagenesis

    Directory of Open Access Journals (Sweden)

    Shi-Ming Fang

    2014-03-01

    Full Text Available Many fungal biosynthetic pathways are silent in standard culture conditions, and activation of the silent pathways may enable access to new metabolites with antitumor activities. The aim of the present study was to develop a practical strategy for microbial chemists to access silent metabolites in fungi. We demonstrated this strategy using a marine-derived fungus Penicillium purpurogenum G59 and a modified diethyl sulphate mutagenesis procedure. Using this strategy, we discovered four new antitumor compounds named penicimutanolone (1, penicimutanin A (2, penicimutanin B (3, and penicimutatin (4. Structures of the new compounds were elucidated by spectroscopic methods, especially extensive 2D NMR analysis. Antitumor activities were assayed by the MTT method using human cancer cell lines. Bioassays and HPLC-photodiode array detector (PDAD-UV and HPLC-electron spray ionization (ESI-MS analyses were used to estimate the activated secondary metabolite production. Compounds 2 and 3 had novel structures, and 1 was a new compound belonging to a class of very rare natural products from which only four members are so far known. Compounds 1–3 inhibited several human cancer cell lines with IC50 values lower than 20 μM, and 4 inhibited the cell lines to some extent. These results demonstrated the effectiveness of this strategy to discover new compounds by activating silent fungal metabolic pathways. These discoveries provide rationale for the increased use of chemical mutagenesis strategies in silent fungal metabolite studies.

    Full Text Available Doubtless to say, the contribution of reading skill to first and second language acquisition is enormous. From one‟s speaking and writing we can more or less conclude how much s/he has read. We can list the characteristics of good readers as follows: rich vocabulary knowledge advanced reading comprehension, accurate grammar usage, broad general knowledge, correct spelling and punctuation, writing ability, and so on. If reading is so powerful, why cannot we promote reading books in our society, particularly among young people? The fact that we are imposed to read books which we think are necessary or compulsory rather than the ones which we would like to read voluntarily, is the main reason why many of us are not able to develop a life-time reading habit. Since compulsory books, such as teacher-selected books are outside one‟s interest; they are destined to be forgotten sometime, or they suffer form shallow reading, or they are mostly returned to their place on the shelf after browsing the initial pages. However, if people of all ages, especially children would read self-selected books they enjoy, they would be surprised to notice the great change inside them. Therefore, the purpose of this study is to revitalize free voluntary reading by referring to Krashen‟s well-known hypotheses. Also, it aims to revive the reader‟s belief in free voluntary reading with theoretical and practical examples

  10. Exergy sustainability.

    2006-05-01

    Exergy is the elixir of life. Exergy is that portion of energy available to do work. Elixir is defined as a substance held capable of prolonging life indefinitely, which implies sustainability of life. In terms of mathematics and engineering, exergy sustainability is defined as the continuous compensation of irreversible entropy production in an open system with an impedance and capacity-matched persistent exergy source. Irreversible and nonequilibrium thermodynamic concepts are combined with self-organizing systems theories as well as nonlinear control and stability analyses to explain this definition. In particular, this paper provides a missing link in the analysis of self-organizing systems: a tie between irreversible thermodynamics and Hamiltonian systems. As a result of this work, the concept of ''on the edge of chaos'' is formulated as a set of necessary and sufficient conditions for stability and performance of sustainable systems. This interplay between exergy rate and irreversible entropy production rate can be described as Yin and Yang control: the dialectic synthesis of opposing power flows. In addition, exergy is shown to be a fundamental driver and necessary input for sustainable systems, since exergy input in the form of power is a single point of failure for self-organizing, adaptable systems.

  15. On the Anglocentricities of current reading research and practice: the perils of overreliance on an "outlier" orthography.

    Science.gov (United States)

    Share, David L

    2008-07-01

    In this critique of current reading research and practice, the author contends that the extreme ambiguity of English spelling-sound correspondence has confined reading science to an insular, Anglocentric research agenda addressing theoretical and applied issues with limited relevance for a universal science of reading. The unique problems posed by this "outlier" orthography, the author argues, have focused disproportionate attention on oral reading accuracy at the expense of silent reading, meaning access, and fluency, and have significantly distorted theorizing with regard to many issues-including phonological awareness, early reading instruction, the architecture of stage models of reading development, the definition and remediation of reading disability, and the role of lexical-semantic and supralexical information in word recognition. The dominant theoretical paradigm in contemporary (word) reading research--the Coltheart/Baron dual-route model (see, e.g., J. Baron, 1977; M. Coltheart, 1978) and, in large measure, its connectionist rivals--arose largely in response to English spelling-sound obtuseness. The model accounts for a range of English-language findings, but it is ill-equipped to serve the interests of a universal science of reading chiefly because it overlooks a fundamental unfamiliar-to-familiar/novice-to-expert dualism applicable to all words and readers in all orthographies.

    2015-04-01

    Full Text Available Microorganisms form diverse multispecies communities in various ecosystems. The high abundance of fungal and bacterial species in these consortia results in specific communication between the microorganisms. A key role in this communication is played by secondary metabolites (SMs, which are also called natural products. Recently, it was shown that interspecies ‘talk’ between microorganisms represents a physiological trigger to activate silent gene clusters leading to the formation of novel SMs by the involved species. This review focuses on mixed microbial cultivation, mainly between bacteria and fungi, with a special emphasis on the induced formation of fungal SMs in co-cultures. In addition, the role of chromatin remodeling in the induction is examined, and methodical perspectives for the analysis of natural products are presented. As an example for an intermicrobial interaction elucidated at the molecular level, we discuss the specific interaction between the filamentous fungi Aspergillus nidulans and Aspergillus fumigatus with the soil bacterium Streptomyces rapamycinicus, which provides an excellent model system to enlighten molecular concepts behind regulatory mechanisms and will pave the way to a novel avenue of drug discovery through targeted activation of silent SM gene clusters through co-cultivations of microorganisms.

  1. Carson in cartoon: a new window onto the noisy reception to Silent Spring.

    Barrow, Mark V

    2012-12-01

    Rachel Carson's Silent Spring generated a firestorm of controversy following its publication in 1962. While numerous scholars have relied on written sources to gage how industry representatives, scientists, government officials, and the public responded to this bestselling book, they have paid much less attention to how visual sources might further our understanding of the context in which Carson wrote, the message she sought to convey, and the impact of her work. This article analyzes sixteen editorial cartoons that appeared in the wake of Carson's book, images that reveal an emerging set of shared understandings about how modern technology presented potential dangers to both humans and the natural world. Using culturally resonant words and images, the cartoonists who editorialized about Carson and her book demonstrate the extent to which her frightening vision of bodily and ecological vulnerability began to permeate society, spawning a counternarrative to the still dominant discourse that linked technological progress, economic development, and the common good. These cartoons thus provide a useful window onto the reception of Silent Spring, the times in which it was published, and the birth of the modern environmental movement.

  2. The "Silent Springs" of Rachel Carson: mass media and the origins of modern environmentalism.

    2001-10-01

    This essay explores the different meanings of the 1960s' pesticide controversy as conveyed by the multiple representations of Rachel Carsons's Silent Spring (1962). I argue that to understand the impact of Carson's work on a heterogeneous audience in the early '60s, we must move beyond an examination of the book, Silent Spring, to consider its other media manifestations, as a serialization for The New Yorker and as a television exposé for "CBS Reports." Each conveyed a unique message stylized for the audience of that particular media. This analysis demonstrates the problems and opportunities for scholars attempting to gauge the influence of a book on the public understanding of science. This argument also suggests that to understand the transition of environmentalism from a grass-roots movement to near universal consensus, we need to examine carefully the role of media in shaping divergent messages for different audiences--a phenomenon that assisted in transforming local environmental issues into a matter of national concern.

    2010-11-01

    Full Text Available The Silent Corticotroph Adenoma (SCA is a pituitary adenoma variant characterized by the immunoreactivity for adrenocorticotropic hormone (ACTH and related peptides, without the clinical signs of Cushing's disease. SCA has been postulated to either secrete structurally abnormal ACTH that is inactive but detectable by immunohistochemistry or radioimmunoassay, or to secrete ACTH intermittently or at low levels continuously. Excess of ACTH has been associated to type II muscle atrophy. We describe a case of type II muscle fibers atrophy associated with silent corticotroph adenoma in a dog. The dog showed moderate to severe proximal muscle wasting and weakness with normal levels of muscle-associated enzymes. In the limb muscle biopsies, type II fibers were uniformly smaller than type I fibers. In temporalis muscles, there were few atrophic fibers, and several irregular areas of loss of enzymatic activity observed in NADH, SDH and COX stains. The tumour showed a trabecular growth pattern and immunohistochemical analysis demonstrated the presence of cytoplasmic immunoreactivity for ACTH. The muscle atrophy was considered to be related to an excess of inactive ACTH. Studying spontaneous occurring rare diseases in animals could help to understand the mechanism of similar diseases in human has well.

    As the exascale era approaches, the increasing capacity of high-performance computing (HPC) systems with targeted power and energy budget goals introduces significant challenges in reliability. Silent data corruptions (SDCs) or silent errors are one of the major sources that corrupt the executionresults of HPC applications without being detected. In this work, we explore a low-memory-overhead SDC detector, by leveraging epsilon-insensitive support vector machine regression, to detect SDCs that occur in HPC applications that can be characterized by an impact error bound. The key contributions are three fold. (1) Our design takes spatialfeatures (i.e., neighbouring data values for each data point in a snapshot) into training data, such that little memory overhead (less than 1%) is introduced. (2) We provide an in-depth study on the detection ability and performance with different parameters, and we optimize the detection range carefully. (3) Experiments with eight real-world HPC applications show thatour detector can achieve the detection sensitivity (i.e., recall) up to 99% yet suffer a less than 1% of false positive rate for most cases. Our detector incurs low performance overhead, 5% on average, for all benchmarks studied in the paper. Compared with other state-of-the-art techniques, our detector exhibits the best tradeoff considering the detection ability and overheads.

A homogenized group of 60 participants was non-randomly chosen and assigned as the control and experimental groups. Those in the control group watched five short animations with dialogue, while those in the experimental group had five short animations which were silent. The procedure lasted 10 sessions. In both groups, the participants were asked to write five writings regarding the subjects of the animations during the term and each of the writings should have contained a minimum of 90 and maximum of 140 words. The participants were provided both oral and written feedback. At the end of the instruction, a sample PET writing posttest was administered to both groups, an independent samples t-test was run on the mean scores of the two groups, and the results (t = -2.02, p = 0.037˂0.05 revealed that the experimental group outperformed the control group.

  6. Silent Polymorphisms: Can the tRNA Population Explain Changes in Protein Properties?

    Directory of Open Access Journals (Sweden)

    Tamara Fernández-Calero

    2016-02-01

    Full Text Available Silent mutations are being intensively studied. We previously showed that the estrogen receptor alpha Ala87’s synonymous polymorphism affects its functional properties. Whereas a link has been clearly established between the effect of silent mutations, tRNA abundance and protein folding in prokaryotes, this connection remains controversial in eukaryotic systems. Although a synonymous polymorphism can affect mRNA structure or the interaction with specific ligands, it seems that the relative frequencies of isoacceptor tRNAs could play a key role in the protein-folding process, possibly through modulation of translation kinetics. Conformational changes could be subtle but enough to cause alterations in solubility, proteolysis profiles, functional parameters or intracellular targeting. Interestingly, recent advances describe dramatic changes in the tRNA population associated with proliferation, differentiation or response to chemical, physical or biological stress. In addition, several reports reveal changes in tRNAs’ posttranscriptional modifications in different physiological or pathological conditions. In consequence, since changes in the cell state imply quantitative and/or qualitative changes in the tRNA pool, they could increase the likelihood of protein conformational variants, related to a particular codon usage during translation, with consequences of diverse significance. These observations emphasize the importance of genetic code flexibility in the co-translational protein-folding process.

  7. Transformation of a Silent Adrencorticotrophic Pituitary Tumor Into Central Nervous System Melanoma

    Directory of Open Access Journals (Sweden)

    Brandon A. Miller MD, PhD

    2013-06-01

    Full Text Available Silent adrenocorticotrophic pituitary adenomas are nonfunctioning pituitary adenomas that express adrenocorticotrophic hormone (ACTH but do not cause the clinical or laboratory features of hypercortisolemia. Primary central nervous system (CNS melanoma is well documented, but rarely originates in the sellar region or pituitary gland. Here we report transformation of an aggressive silent adrenocorticotrophic pituitary adenoma that transformed into CNS melanoma and review other presentations of pituitary melanoma. A 37-year-old woman initially presented with apoplexy and an invasive nonfunctioning pituitary macroadenoma for which she underwent transphenoidal surgery. The patient underwent 3 subsequent surgeries as the tumor continued to progress. Pathology from the first 3 operations showed pituitary adenoma or carcinoma. Pathology from the final surgery showed melanoma and the magnetic resonance imaging characteristics of the tumor had changed to become consistent with CNS melanoma. Dermatologic and ophthalmologic examinations did not identify cutaneous or ocular melanoma. The patient’s disease progressed despite aggressive surgical, medical and radiologic treatment. To our knowledge, this is the first report demonstrating transformation of a primary pituitary tumor into melanoma. The mechanism of tumor transformation is unclear, but it is possible that a mutation in the original ACTH-producing tumor lead to increased cleavage of pro-opiomelanocortin or ACTH into α-melanocyte-stimulating hormone, which in turn stimulated the expression of microopthalmia transcription factor, leading to melanocytic phenotype transformation.

    Full Text Available Background. Insulin resistance (IR is part of the metabolic syndrome (Mets that develops after lifestyle changes and obesity. Although the association between Mets and myocardial injury is well known, the effect of IR on myocardial damage remains unclear. Methods and Results. We studied 2200 normal subjects who participated in a community-based health check in the town of Takahata in northern Japan. The presence of IR was assessed by homeostasis model assessment ratio, and the serum level of heart-type fatty acid binding protein (H-FABP was measured as a maker of silent and ongoing myocardial damage. H-FABP levels were significantly higher in subjects with IR and Mets than in those without metabolic disorder regardless of gender. Multivariate logistic analysis showed that the presence of IR was independently associated with latent myocardial damage (odds ratio: 1.574, 95% confidence interval 1.1–2.3 similar to the presence of Mets. Conclusions. In a screening of healthy subjects, IR and Mets were similarly related to higher H-FABP levels, suggesting that there may be an asymptomatic population in the early stages of metabolic disorder that is exposed to myocardial damage and might be susceptible to silent heart failure.

    Insects are capable of conducting silent flights. This is attributed to its specially designed wing material properties for the control of vibration and surface morphing during the flapping flight. In current work, we focus on the roles of dynamic wing morphing on the unsteady vortex dynamics of a cicada in steady flight. A 3D image-based surface reconstruction method is used to obtain kinematical and morphological data of cicada wings from high-quality high-speed videos. The observed morphing wing kinematics is highly complex and a singular value decomposition method is used to decompose the wing motion to several dominant modes with distinct motion features. A high-fidelity immersed-boundary-based flow solver is then used to study the vortex dynamics in details. The results show that vortical structures closely relate to the morphing mode, which plays key role in the development and attachment of leading-edge vortex (LEV), thus helps the silent flapping of the cicada wings.

    Full Text Available In recent decades, the image of the international business environment has changed significantly. Studies conducted by UNCTAD shows that corporate phenomenon developments in the world economy is growing. Without claiming to present an exhaustive topic so vast we tried to capture some "facets" of sustainable development from the perspective of multinational corporations, given the expansion of these economic entities and strengthening their power in the global economy. We present more negative aspects of the actions of multinational corporations in terms of sustainable development, it is very important to know both sides of the coin, which will not only help transnational giants including release. Based on issues such as corporate social responsibility, environmental pollution and workers' rights, we sought to counter official statements. The conclusion is that these economic entities are real forces that can not be ignored in today's world and the obvious problem of sustainable development can not be addressed independently of the phenomenon, context we also identified some possible solutions to conflict of corporations and essence of the concept of sustainable development.

  11. Measuring the prevalence of regional mutation rates: an analysis of silent substitutions in mammals, fungi, and insects

    Directory of Open Access Journals (Sweden)

    Tuch Brian B

    2008-06-01

    Full Text Available Abstract Background The patterns of mutation vary both within and across genomes. It has been shown for a few mammals that mutation rates vary within the genome, while for unknown reasons, the sensu stricto yeasts have uniform rates instead. The generality of these observations has been unknown. Here we examine silent site substitutions in a more expansive set (20 mammals, 27 fungi, 4 insects to determine why some genomes demonstrate this mosaic distribution and why others are uniform. Results We applied several intragene and intergene correlation tests to measure regional substitution patterns. Assuming that silent sites are a reasonable approximation to neutrally mutating sequence, our results show that all multicellular eukaryotes exhibit mutational heterogeneity. In striking contrast, all fungi are mutationally uniform – with the exception of three Candida species: C. albicans, C. dubliniensis, and C. tropicalis. We speculate that aspects of replication timing may be responsible for distinguishing these species. Our analysis also reveals classes of genes whose silent sites behave anomalously with respect to the mutational background in many species, indicating prevalent selective pressures. Genes associated with nucleotide binding or gene regulation have consistently low silent substitution rates in every mammalian species, as well as multiple fungi. On the other hand, receptor genes repeatedly exhibit high silent substitution rates, suggesting they have been influenced by diversifying selection. Conclusion Our findings provide a framework for understanding the regional mutational properties of eukaryotes, revealing a sharp difference between fungi and multicellular species. They also elucidate common selective pressures acting on eukaryotic silent sites, with frequent evidence for both purifying and diversifying selection.

    Richardson, Fiona M; Seghier, Mohamed L; Leff, Alex P; Thomas, Michael S C; Price, Cathy J

    2011-06-01

    Contemporary models of the neural system that supports reading propose that activity in a ventral occipitotemporal area (vOT) drives activity in higher-order language areas, for example, those in the posterior superior temporal sulcus (pSTS) and anterior superior temporal sulcus (aSTS). We used fMRI with dynamic causal modeling (DCM) to investigate evidence for other routes from visual cortex to the left temporal lobe language areas. First we identified activations in posterior inferior occipital (iO) and vOT areas that were more activated for silent reading than listening to words and sentences; and in pSTS and aSTS areas that were commonly activated for reading relative to false-fonts and listening to words relative to reversed words. Second, in three different DCM analyses, we tested whether visual processing of words modulates activity from the following: (1) iO→vOT, iO→pSTS, both, or neither; (2) vOT→pSTS, iO→pSTS, both or neither; and (3) pSTS→aSTS, vOT→aSTS, both, or neither. We found that reading words increased connectivity (1) from iO to both pSTS and vOT; (2) to pSTS from both iO and vOT; and (3) to aSTS from both vOT and pSTS. These results highlight three potential processing streams in the occipitotemporal cortex: iO→pSTS→aSTS; iO→vOT→aSTS; and iO→vOT→pSTS→aSTS. We discuss these results in terms of cognitive models of reading and propose that efficient reading relies on the integrity of all these pathways.

  18. Not all reading is alike: Task modulation of magnetic evoked response to visual word

    Directory of Open Access Journals (Sweden)

    Pavlova A. A.

    2017-09-01

    Full Text Available Background. Previous studies have shown that brain response to a written word depends on the task: whether the word is a target in a version of lexical decision task or should be read silently. Although this effect has been interpreted as an evidence for an interaction between word recognition processes and task demands, it also may be caused by greater attention allocation to the target word. Objective. We aimed to examine the task effect on brain response evoked by non- target written words. Design. Using MEG and magnetic source imaging, we compared spatial-temporal pattern of brain response elicited by a noun cue when it was read silently either without additional task (SR or with a requirement to produce an associated verb (VG. Results.The task demands penetrated into early (200-300 ms and late (500-800 ms stages of a word processing by enhancing brain response under VG versus SR condition. The cortical sources of the early response were localized to bilateral inferior occipitotemporal and anterior temporal cortex suggesting that more demanding VG task required elaborated lexical-semantic analysis. The late effect was observed in the associative auditory areas in middle and superior temporal gyri and in motor representation of articulators. Our results suggest that a remote goal plays a pivotal role in enhanced recruitment of cortical structures underlying orthographic, semantic and sensorimotor dimensions of written word perception from the early processing stages. Surprisingly, we found that to fulfil a more challenging goal the brain progressively engaged resources of the right hemisphere throughout all stages of silent reading. Conclusion. Our study demonstrates that a deeper processing of linguistic input amplifies activation of brain areas involved in integration of speech perception and production. This is consistent with theories that emphasize the role of sensorimotor integration in speech understanding.

    To characterize the spatial relationship between activations related to language-induced seizure activity, language processing, and motor control in patients with reading epilepsy. We recorded and simultaneously monitored several physiological parameters [voice-recording, electromyography (EMG), electrocardiography (ECG), electroencephalography (EEG)] during blood oxygen level-dependent (BOLD) functional magnetic resonance imaging (fMRI) in nine patients with reading epilepsy. Individually tailored language paradigms were used to induce and record habitual seizures inside the MRI scanner. Voxel-based morphometry (VBM) was used for structural brain analysis. Reading-induced seizures occurred in six out of nine patients. One patient experienced abundant orofacial reflex myocloni during silent reading in association with bilateral frontal or generalized epileptiform discharges. In a further five patients, symptoms were only elicited while reading aloud with self-indicated events. Consistent activation patterns in response to reading-induced myoclonic seizures were observed within left motor and premotor areas in five of these six patients, in the left striatum (n = 4), in mesiotemporal/limbic areas (n = 4), in Brodmann area 47 (n = 3), and thalamus (n = 2). These BOLD activations were overlapping or adjacent to areas physiologically activated during language and facial motor tasks. No subtle structural abnormalities common to all patients were identified using VBM, but one patient had a left temporal ischemic lesion. Based on the findings, we hypothesize that reflex seizures occur in reading epilepsy when a critical mass of neurons are activated through a provoking stimulus within corticoreticular and corticocortical circuitry subserving normal functions.

  3. Reading Performance Is Predicted by More Than Phonological Processing

    2014-09-01

    Full Text Available We compared three phonological processing components (phonological awareness, rapid automatized naming and phonological memory, verbal working memory, and attention control in terms of how well they predict the various aspects of reading: word recognition, pseudoword decoding, fluency and comprehension, in a mixed sample of 182 children ages 8-12 years. Participants displayed a wide range of reading ability and attention control. Multiple regression was used to determine how well the phonological processing components, verbal working memory, and attention control predict reading performance. All equations were highly significant. Phonological memory predicted word identification and decoding. In addition, phonological awareness and rapid automatized naming predicted every aspect of reading assessed, supporting the notion that phonological processing is a core contributor to reading ability. Nonetheless, phonological processing was not the only predictor of reading performance. Verbal working memory predicted fluency, decoding and comprehension, and attention control predicted fluency. Based upon our results, when using Baddeley’s model of working memory it appears that the phonological loop contributes to basic reading ability, whereas the central executive contributes to fluency and comprehension, along with decoding. Attention control was of interest as some children with ADHD have poor reading ability even if it is not sufficiently impaired to warrant diagnosis. Our finding that attention control predicts reading fluency is consistent with prior research which showed sustained attention plays a role in fluency. Taken together, our results suggest that reading is a highly complex skill that entails more than phonological processing to perform well.

    Purpose: To investigate the safety and effectiveness of stereotactic radiosurgery (SRS) in patients with a silent corticotroph adenoma (SCA) compared with patients with other subtypes of non–adrenocorticotropic hormone staining nonfunctioning pituitary adenoma (NFA). Methods and Materials: The clinical features and outcomes of 104 NFA patients treated with SRS in our center between September 1994 and August 2012 were evaluated. Among them, 34 consecutive patients with a confirmatory SCA were identified. A control group of 70 patients with other subtypes of NFA were selected for review based on comparable baseline features, including sex, age at the time of SRS, tumor size, margin radiation dose to the tumor, and duration of follow-up. Results: The median follow-up after SRS was 56 months (range, 6-200 months). No patients with an SCA developed Cushing disease during the follow-up. Tumor control was achieved in 21 of 34 patients (62%) in the SCA group, compared with 65 of 70 patients (93%) in the NFA group. The median progression-free survival (PFS) was 58 months in the SCA group. The actuarial PFS was 73%, 46%, and 31% in the SCA group and was 94%, 87%, and 87% in the NFA group at 3, 5, and 8 years, respectively. Silent corticotroph adenomas treated with a dose of ≥17 Gy exhibited improved PFS. New-onset loss of pituitary function developed in 10 patients (29%) in the SCA group, whereas it occurred in 18 patients (26%) in the NFA group. Eight patients (24%) in the SCA group experienced worsening of a visual field deficit or visual acuity attributed to the tumor progression, as did 6 patients (9%) in the NFA group. Conclusion: Silent corticotroph adenomas exhibited a more aggressive course with a higher progression rate than other subtypes of NFAs. Stereotactic radiosurgery is an important adjuvant treatment for control of tumor growth. Increased radiation dose may lead to improved tumor control in SCA patients.

  11. Reading disorders and dyslexia.

    Hulme, Charles; Snowling, Margaret J

    2016-12-01

    We review current knowledge about the nature of reading development and disorders, distinguishing between the processes involved in learning to decode print, and the processes involved in reading comprehension. Children with decoding difficulties/dyslexia experience deficits in phoneme awareness, letter-sound knowledge and rapid automatized naming in the preschool years and beyond. These phonological/language difficulties appear to be proximal causes of the problems in learning to decode print in dyslexia. We review data from a prospective study of children at high risk of dyslexia to show that being at family risk of dyslexia is a primary risk factor for poor reading and children with persistent language difficulties at school entry are more likely to develop reading problems. Early oral language difficulties are strong predictors of later difficulties in reading comprehension. There are two distinct forms of reading disorder in children: dyslexia (a difficulty in learning to translate print into speech) and reading comprehension impairment. Both forms of reading problem appear to be predominantly caused by deficits in underlying oral language skills. Implications for screening and for the delivery of robust interventions for language and reading are discussed.

    Motor balance in developmental stuttering (DS) was investigated with Transcranial Magnetic Stimulation (TMS), with the aim to define novel neural markers of persistent DS in adulthood. Eleven DS adult males were evaluated with TMS on tongue primary motor cortex, compared to 15 matched fluent speakers, in a "state" condition (i.e. stutterers vs. fluent speakers, no overt stuttering). Motor and silent period thresholds (SPT), recruitment curves, and silent period durations were acquired by recording tongue motor evoked potentials. Tongue silent period duration was increased in DS, especially in the left hemisphere (Pstuttering severity. Pre-TMS electromyography data gave overlapping evidence. Findings suggest the existence of a complex intracortical balance in DS tongue primary motor cortex, with a particular interplay between excitatory and inhibitory mechanisms, also in neural substrates related to silent periods. Findings are discussed with respect to functional and structural impairments in stuttering, and are also proposed as novel neural markers of a stuttering "state" in persistent DS, helping to define more focused treatments (e.g. neuro-modulation).

    Full Text Available Congenital diaphragmatic hernia (CDH is a rare condition. The reported incidence of intrathoracic renal ectopia due to CDH is also rare. A right-sided thoracic kidney is much less common due to the location of the liver. Isolated intrathoracic kidney is usually asymptomatic and diagnosed incidentally on chest imaging. The authors report on a 21days old female infant with late-presenting right sided congenital diaphragmatic hernia associated with intrathoracic ectopic kidney and adrenal gland. Prenatal ultrasound showed no pathology. A female baby was investigated for silent tachypnoea, a chest x-ray confirmed the diagnosis of congenital diaphragmatic hernia, the postnatal ultrasound revealed a right-sided kidney herniation. On computed tomography (CT scan intrathoracic ectopic kidney was diagnosed. CDH is an delivery room emergency. This case had complex anatomy of right side CDH and intrathoracic kidney and presentation was only tachypnoea. Hence we are reporting this case.

    2009-04-24

    Great earthquakes have repeatedly occurred on the plate interface in a few shallow-dipping subduction zones where the subducting and overriding plates are strongly locked. Silent earthquakes (or slow slip events) were recently discovered at the down-dip extension of the locked zone and interact with the earthquake cycle. Here, we show that locally observed converted SP arrivals and teleseismic underside reflections that sample the top of the subducting plate in southern Mexico reveal that the ultra-slow velocity layer (USL) varies spatially (3 to 5 kilometers, with an S-wave velocity of approximately 2.0 to 2.7 kilometers per second). Most slow slip patches coincide with the presence of the USL, and they are bounded by the absence of the USL. The extent of the USL delineates the zone of transitional frictional behavior.

    We report a 27-year-old woman with amenorrhea and galactorrhea with mildly elevated serum prolactin levels. Her MRI demonstrated a cystic macroadenoma in the left aspect of the sella and a small microadenoma in the right aspect of the sella. Endoscopic transsphenoidal resection of the tumors revealed two histologically distinct tumors. The left tumor was consistent with a silent corticotroph macroadenoma and the right tumor was a prolactin producing microadenoma. Isolated double pituitary adenomas that are clearly separated by normal pituitary gland tissue are extremely rare. The incidence is approximately 0.37-2.6%. The coexistence of double adenomas can pose diagnostic and management challenges for the pituitary neuroendocrine team. Copyright © 2015 Elsevier Ltd. All rights reserved.

    A certain 'O Uplavici' was cited for more than fifty years, although he had never existed. This error probably came from a misinterpretation of the Czech language, in which the real author's name--Hlava--can mean 'Title'. It was finally recognized, which was not the case for the author of the sentence: 'I have no need of hope to take action, nor of success to persevere', it is still regularly attributed in France to William I, Prince of Orange, called the Silent. It is a mistake, and no serious reference certifies that an historical figure would have pronounced this sentence. It was written by the historian Mignet in 1841, to describe the character of William III, Prince of Orange and King of England. It was then used in 1875 by Jules Verne, to describe a character in 'The Mysterious Island'. Copyright © 2011. Published by Elsevier SAS.

    We have studied the low pressure silent discharge type active oxygen generator in terms of the application to the formation of oxide thin films. In this paper the oxidation power of active oxygen in the oxide thin film formation is compared with that of oxygen and ozone by forming silicon oxide thin films. It was confirmed that the oxidation power is in turn of active oxygen > ozone > oxygen from the experimental result of the number of x in SiOx thin film. Furthermore we applied active oxygen to the formation of the thin film high temperature super conductor and active oxygen was found to be effective to the formation of the thin film with high performance.

    Full Text Available A silent solid endocrine tumor of pancreas, intraductal adenocarcinoma of pancreas, is the fourth leading cancer-related death in the US. However, it is expected to become the third leading cause by 2030 owing to delayed diagnosis and slow progress in management. Chronic pancreatitis is at risk for pancreatic ductal adenocarcinoma (PDAC. PDAC is diagnostic with transabdominal sonogram, blood test such as carbohydrate antigen 19-9 (CA 19-9, and imaging. PDAC has a dismal prognosis. The survival rate in 5 years is barely 6%, while late detection rate is 80–85% with unresectable stage upon diagnosis. Here, we present a 51-year-old asymptomatic female with intermittent constipation and abdominal pain for 1 month with obstructive jaundice with PDAC with liver metastasis.

    As an attempt to utilize of rare earth elements as a novel method to activate the silent genes in fungus, the marine-derived fungus Penicillium citrinum was cultured under ordinary laboratory fermentation conditions in the presence of scandium chloride (ScCl 3 , 50 μM), and chemical investigation led to the isolation and characterization of three new peptide derivatives (1-3), along with four known pyrrolidine alkaloids (4-7). Those structures were elucidated by spectroscopic data interpretation, as well as chemical reactions. Comparative metabolic profiling of the culture extracts (with/without scandium chloride) indicated that compounds 1-3 scarcely detected in the absence of ScCl 3 . In addition, the antibacterial and cytotoxic activities of all isolated products were evaluated. Copyright © 2017. Published by Elsevier B.V.

    Full Text Available Celiac disease is an autoimmune disorder in which a genetic predisposition and the ingestion of wheat gluten triggers a deleterious immune response. This response is complex and may lead to manifestations other than enteropathyha: hepatitis, dermatitis and neuropathy. There is higher risk for neoplasia. We observed an atypical case, corresponding to a 69-year old female presenting with complicated celiac disease. The patient was referred following the histological examination of an enterectomy specimen, which unexpectedly revealed an enteropathy-associated T cell lymphoma in a background of celiac disease. Patient’s previous medical history comprised several abdominal surgical procedures, without other prior symptoms suggestive of celiac disease. Indeed, the patient was obese and no signs of malabsortion were apparent. This case draws our attention to clinically silent celiac disease, which represents a diagnostic challenge. Thus, this should be kept in mind whenever a patient presents with abdominal relapsing complications, otherwise unexplained.

    A sample of pyrite rich bituminous coal collected from the main coal seam of Maghara mine, northern sinai, was treated by ozone plasma. The latter was synthesized using silent discharge method (10 kv a.c. and 50 hz). The room temperature Moessbauer spectra of untreated coal sample was easily fitted to two doublet, whose parameters matched those of pyrite (FeS sub 2) and sulfate (FeSO sub 4.H sub 2 O) in addition to hematite. After treatment by ozone plasma, a doublet ascribed to pyrite was observed. The extent of pyrite oxidation to jarosite (Fe sub 2 (SO sub 4) sub 3. nH sub 2 O) was monitored by their relative spectral areas, the incomplete oxidation of pyrite may be attributed to the presence of calcium sulfate layer which acts a screen of ozone.

    Bilateral congenital vocal fold paralysis (BVFP) may result from multiple etiologies or remain idiopathic when no real cause can be identified. If obstructive dyspnea is significant and requires urgent stabilization of the airway, then intubation is performed first and an MRI of the brain is conducted to rule out an Arnold-Chiari malformation that can benefit from a shunt procedure and thus alleviate the need for a tracheostomy. Clinically silent subdural hemorrhage without any birth trauma represents another cause of neonatal BVFP that resolves spontaneously within a month. It is of clinical relevance to recognize this potential cause of BVFP as its short duration may alleviate the need for a tracheostomy. In this article, we present such a case and review the literature to draw the otolaryngologist's attention to this possible etiology. Copyright © 2012. Published by Elsevier Ireland Ltd.

  14. The silent social/emotional signals in left and right cheek poses: a literature review.

    2013-01-01

    When posing for a painted or photographic portrait, people are more likely to offer their left, rather than right, cheek (e.g., the Mona Lisa). Why? This paper reviews research investigating the left cheek bias, and the reasons underlying this posing asymmetry. Ruling out mechanical and perceptual biases, the paper focuses on the silent emotional and social signals conveyed by left and right cheek poses, demonstrating that people intuitively offer the left cheek to express emotion and perceive left cheek poses as more emotional. Moreover, because the left cheek appears more emotionally expressive, we unconsciously use cheek shown as a cue when presenting or determining academic specialisation, scientific standing, and even political affiliation. The research is consistent in suggesting that something as subtle as a 15° head turn implicitly influences others' perceptions: if you want to be perceived as open and creative, rather than dry and scientific, it might be time to turn the other cheek.

    Corticotroph adenomas are extremely rare in children and adolescents. We present a 15-year-old boy who was investigated for delayed puberty (A1P2G1, bilateral testicular volumes of 3 mL each). There was no clinical or laboratory evidence suggestive of chronic illness, and the initial clinical impression was constitutional delay in puberty. Subsequently, MRI scan of the brain revealed the presence of a mixed cystic and solid pituitary lesion slightly displacing the optic chiasma. The lesion was removed by transphenoidal surgery and the biopsy confirmed the lesion to be pituitary adenoma. Furthermore, the adenoma cells also had Crooke's hyaline changes and were intensely positive for ACTH. However there was no clinical/biochemical evidence of ACTH excess. There was a spontaneous pubertal progression twelve months after the surgery (A2P4G4, with bilateral testicular volume of 8 mL). Crooke's cell adenoma is an extremely rare and aggressive variant of corticotroph adenoma that can uncommonly present as a silent corticotroph adenoma in adults. We report for the first time Crooke's cell adenoma in an adolescent boy presenting with delayed puberty. Constitutional delay of growth and puberty (CDGP) is a diagnosis of exclusion; hence a systematic and careful review should be undertaken while assessing boys with delayed puberty.Crooke's cell adenomas are a group of corticotroph adenomas that can rarely present in childhood and adolescence with delayed puberty.Crooke's cell adenomas can be clinically silent but are potentially aggressive tumours that require careful monitoring.

    The role of adrenal scintigraphy in the noninvasive characterization of silent adrenal masses was investigated in 40 patients. The mass had been detected by US or CT performed in the evaluation of non-malignant extra-adrenal diseases (25 cases) or during staging or follow-up of a malignant extra-adrenal neoplasm (15 cases). In all cases radio-cholesterol scintigraphy (74 MBq i.v. of 131I-6 beta-iodomethylnorcholesterol in 19 cases; 11 MBq i.v. of 75Se-6 beta-selenomethylnorcholesterol in 21 cases) was performed; in 7 cases also 131I-MIBG scan (18.5-37 MBq i.v.) was carried out. When compared with CT data, radiocholesterol scintigraphy (standard or after suppression with dexamethasone) showed: concordant uptake (increased uptake of radiocholesterol on the side of the adrenal mass) in 24/26 patients with adrenal cortical adenoma; discordant uptake (absent or decreased uptake on the side of the adrenal mass) in 12 patients: 5 with adrenal metastases and 7 with non-adenomatous benign space-occupying lesions (2 ganglioneuromas, 1 post-traumatic hemorrhagic lesion, 3 adrenal cysts, 1 myelolipoma); indeterminate uptake (symmetric bilateral uptake) in 4 patients: 2 with a small adenoma, 1 with adrenal metastasis and 1 with a "false incidentaloma" (hepatic regenerative nodule). The results confirm the utility of radiocholesterol scintigraphy in demonstrating the benignity of adrenal lesions (particularly in identifying adrenocortical adenomas) and assess its place among the procedures used to characterize silent adrenal masses. The possible use of MIBG scintigraphy is also discussed.

Don Siegel’s Dirty Harry (1971, famously labeled «fascist» by prominent film critic Pauline Kael, nonetheless represented something new and unique—the “Silent Majority’s” entry into liberal New Hollywood, a veritable counter-reformation to the new social movements having sprung up in the late Sixties and early Seventies. Far from the traditional American Right, however, and distinctly un-Fascist (in as much as the term means more than a simple epithet, these films acted to unite traditional European philosophy and revolutionary thought with organic conservative American tendencies, resulting in hybrid films which challenged the new social movements, while working within the medium of liberal New American Cinema. The article will address three themes from the era: violence and race in the city, revenge against “liberated women”, and fear and loathing of homosexuality. In each instance, using primary evidence from films and critical reviews from the Seventies and the present era, in addition to American and European theorists, the article will show how the counter-revolution in Seventies cinema failed to expunge the “revolutionary spirit” of the era. Rather, the Silent Majority’s visions of visual violence and reactionary values became part and parcel of the new liberated culture of the “Me Decade,” forever bounding the conservative celluloid revolt to the new cinematic culture.

  1. New insights into symptomatic or silent atrial fibrillation complicating acute myocardial infarction.

    Atrial fibrillation (AF) is the most frequent heart rhythm disorder in the general population and contributes not only to a major deterioration in quality of life but also to an increase in cardiovascular morbimortality. The onset of AF in the acute phase of myocardial infarction (MI) is a major event that can jeopardize the prognosis of patients in the short-, medium- and long-term, and is a powerful predictor of a poor prognosis after MI. The suspected mechanism underlying the excess mortality is the drop in coronary flow linked to the acceleration and arrhythmic nature of the left ventricular contractions, which reduce the left ventricular ejection fraction. The principal causes of AF-associated death after MI are linked to heart failure. Moreover, the excess risk of death in these heart failure patients has also been associated with the onset of sudden death. Whatever its form, AF has a major negative effect on patient prognosis. In recent studies, symptomatic AF was associated with inhospital mortality of 17.8%, to which can be added mortality at 1year of 18.8%. Surprisingly, silent AF also has a negative effect on the prognosis, as it is associated with an inhospital mortality rate of 10.4%, which remains high at 5.7% at 1year. Moreover, both forms of AF are independent predictors of mortality beyond traditional risk factors. The frequency and seriousness of silent AF in the short- and long-term, which were until recently rarely studied, raises the question of systematically screening for it in the acute phase of MI. Consequently, the use of continuous ECG monitoring could be a simple, effective and inexpensive solution to improve screening for AF, even though studies are still necessary to validate this strategy. Finally, complementary studies also effect of oxidative stress and endothelial dysfunction, which seem to play a major role in triggering this rhythm disorder. Copyright © 2015 Elsevier Masson SAS.

    Hyperthyroidism is a risk factor for reduced bone mineral density (BMD) and osteoporotic fractures. Vertebral fracture assessment (VFA) by dual-energy X-ray absorptiometry (DXA) is a radiological method of visualization of the spine, which enables patient comfort and reduced radiation exposure. This study was carried out to evaluate BMD and the prevalence of silent vertebral fractures in young men with hyperthyroidism. We conducted a cross-sectional study in a group of Portuguese men aged up to 50 years and matched in hyperthyroidism (n=24) and control (n=24) groups. A group of 48 Portuguese men aged up to 50 years was divided and matched in hyperthyroidism (n=24) and control (n=24) groups. BMD (g/cm(2)) at L1-L4, hip, radius 33%, and whole body as well as the total body masses (kg) were studied by DXA. VFA was used to detect fractures and those were classified by Genant's semiquantitative method. No patient had previously been treated for hyperthyroidism, osteoporosis, or low bone mass. Adequate statistical tests were used. The mean age, height, and total fat mass were similar in both groups (P≥0.05). The total lean body mass and the mean BMD at lumbar spine, hip, and whole body were significantly decreased in the hyperthyroidism group. In this group, there was also a trend for an increased prevalence of reduced BMD/osteoporosis and osteoporotic vertebral fractures. The results obtained using VFA technology (confirmed by X-ray) suggest that the BMD changes in young men with nontreated hyperthyroidism may lead to the development of osteoporosis and vertebral fractures. This supports the pertinence of using VFA in the routine of osteoporosis assessment to detect silent fractures precociously and consider early treatment. © 2015 European Society of Endocrinology.

    To determine the association between silent ischemic lesions (SILs) on baseline brain MRI and recurrent stroke in young adults with first-ever ischemic stroke. This was a single-center retrospective study of adult patients aged 18-50 years with first-ever ischemic stroke investigated by brain MRI between 2002 and 2009. Silent brain infarcts (SBIs) were defined as focal T2 hyperintensities ≥ 3 mm without corresponding focal symptoms, and leukoaraiosis was defined as focal, multifocal, or confluent hyperintensities on T2-weighted sequences. The primary outcome was recurrent stroke. A forward stepwise Cox regression model was used to determine whether SILs were independently associated with recurrent stroke. A total of 271 eligible patients were identified in the database: 89 did not undergo MRI imaging and 12 patients had inadequate follow-up, leaving a study population of 170 patients. MRI demonstrated SILs in 48 of 170 (28.2) patients. No patients had isolated leukoaraiosis. Hypertension (p = 0.049), migraine with aura (p = 0.02), and cardiovascular disease (p = 0.04) were associated with SIL. Mean follow-up duration was 25 ± 7 months. Among patients with SILs, 11 of 48 (23%) had a recurrent stroke vs 8 of 122 (6.5%) patients without SIL (p = 0.003). After multivariate Cox regression, SILs remained independently associated with recurrent stroke (hazard ratio [HR] 3.2, 95% confidence interval [CI] 1.2-8.6, p = 0.02), as did the combination of SBIs and leukoaraiosis (HR 7.3, 95% CI 2.3-22.9, p = 0.003). In adults ≤ 50 years old with first-ever ischemic stroke, SILs are common and independently predict recurrent stroke.

  4. The Sound of Silence: Activating Silent Biosynthetic Gene Clusters in Marine Microorganisms

    Full Text Available Unlocking the rich harvest of marine microbial ecosystems has the potential to both safeguard the existence of our species for the future, while also presenting significant lifestyle benefits for commercial gain. However, while significant advances have been made in the field of marine biodiscovery, leading to the introduction of new classes of therapeutics for clinical medicine, cosmetics and industrial products, much of what this natural ecosystem has to offer is locked in, and essentially hidden from our screening methods. Releasing this silent potential represents a significant technological challenge, the key to which is a comprehensive understanding of what controls these systems. Heterologous expression systems have been successful in awakening a number of these cryptic marine biosynthetic gene clusters (BGCs. However, this approach is limited by the typically large size of the encoding sequences. More recently, focus has shifted to the regulatory proteins associated with each BGC, many of which are signal responsive raising the possibility of exogenous activation. Abundant among these are the LysR-type family of transcriptional regulators, which are known to control production of microbial aromatic systems. Although the environmental signals that activate these regulatory systems remain unknown, it offers the exciting possibility of evoking mimic molecules and synthetic expression systems to drive production of potentially novel natural products in microorganisms. Success in this field has the potential to provide a quantum leap forward in medical and industrial bio-product development. To achieve these new endpoints, it is clear that the integrated efforts of bioinformaticians and natural product chemists will be required as we strive to uncover new and potentially unique structures from silent or cryptic marine gene clusters.

  5. On-line changing of thinking about words: the effect of cognitive context on neural responses to verb reading.

    Activity in frontocentral motor regions is routinely reported when individuals process action words and is often interpreted as the implicit simulation of the word content. We hypothesized that these neural responses are not invariant components of action word processing but are modulated by the context in which they are evoked. Using fMRI, we assessed the relative weight of stimulus features (i.e., the intrinsic semantics of words) and contextual factors, in eliciting word-related sensorimotor activity. Participants silently read action-related and state verbs after performing a mental rotation task engaging either a motor strategy (i.e., referring visual stimuli to their own bodily movements) or a visuospatial strategy. The mental rotation tasks were used to induce, respectively, a motor and a nonmotor "cognitive context" into the following silent reading. Irrespective of the verb category, reading in the motor context, compared with reading in the nonmotor context, increased the activity in the left primary motor cortex, the bilateral premotor cortex, and the right somatosensory cortex. Thus, the cognitive context induced by the preceding motor strategy-based mental rotation modulated word-related sensorimotor responses, possibly reflecting the strategy of referring a word meaning to one's own bodily activity. This pattern, common to action and state verbs, suggests that the context in which words are encountered prevails over the intrinsic semantics of the stimuli in mediating the recruitment of sensorimotor regions.

  6. Interleaved silent steady state (ISSS) imaging: a new sparse imaging method applied to auditory fMRI.

    2006-02-01

    The acoustic scanner noise that is generated by rapid gradient switching in echo planar imaging (EPI) is an important confounding factor in auditory fMRI. "Sparse imaging" designs overcome the influence of scanner noise on stimulus presentation by acquiring single brain volumes following a silent stimulus presentation period. However, conventional sparse imaging requires assumptions about the time-to-peak of the evoked hemodynamic response and reduces the amount of EPI data which can be acquired and hence statistical power. In this article, we describe an "interleaved silent steady state" (ISSS) sampling scheme in which we rapidly acquire a set of EPI volumes following each silent stimulus presentation period. We avoid T1-related signal decay during the acquisition of the EPI volumes by maintaining the steady state longitudinal magnetization with a train of silent slice-selective excitation pulses during the silent period, ensuring that signal contrast is constant across successive scans. A validation study comparing ISSS to conventional sparse imaging demonstrates that ISSS imaging provides time course information that is absent in conventional sparse imaging data. The ISSS sequence has a temporal resolution like event-related (ER) imaging within a single trial (unlike conventional sparse imaging, where ER-like temporal resolution can only be achieved by compiling data across many jittered trials of the same stimulus type). This temporal resolution within trials makes ISSS particularly suitable for experiments in which a) scanner noise would interfere with the perception and processing of the stimulus; b) stimuli are several seconds in duration, and activation is expected to evolve and change as the stimulus unfolds; and c) it is impractical to present a single stimulus more than once (for example, repetition priming or familiarity effects would be expected).

    Full Text Available In four ways, massively multiplayer online role-playing games may serve as tools for advancing sustainability goals, and as laboratories for developing alternatives to current social arrangements that have implications for the natural environment. First, by moving conspicuous consumption and other usually costly status competitions into virtual environments, these virtual worlds might reduce the need for physical resources. Second, they provide training that could prepare individuals to be teleworkers, and develop or demonstrate methods for using information technology to replace much transportation technology, notably in commuting. Third, virtual worlds and online games build international cooperation, even blending national cultures, thereby inching us toward not only the world consciousness needed for international agreements about the environment, but also toward non-spatial government that cuts across archaic nationalisms. Finally, realizing the potential social benefits of this new technology may urge us to reconsider a number of traditional societal institutions.

The message can be knowledge, skills, ideas, experiences, and many others. Through the process of communication, the people can receive the message or information. To avoid misunderstanding in the process of communication, media are needed in the process of teaching. Magazine can be other alternative as reading material in the classroom. Magazine as reading material has appeal for the students. To make the students get information from magazine, the teacher can ask the students to observe table of content and giving the students training to use it. Like, what is done on text book. Distinguishing informative reading material with fictive reading, important to know students in reading magazine. Like analyzing advertisements to detect propaganda.

    Many studies have shown that sustained silent reading (SSR), where students read silently for a short period of time every day in class, helps improve their reading abilities. Compared to SSR, few studies have been done on listening activities which allow students to listen for some minutes of each class. In this paper, listening activities where students listen to English for a short period of time of each class are referred to as "sustained listening" (SL) and its effects on university EFL ...

  8. Sustainability Science Needs Sustainable Data!

    Sustainability science (SS) is an 'emerging field of research dealing with the interactions between natural and social systems, and with how those interactions affect the challenge of sustainability: meeting the needs of present and future generations while substantially reducing poverty and conserving the planet's life support systems' (Kates, 2011; Clark, 2007). Bettencourt & Kaur (2011) identified more than 20,000 scientific papers published on SS topics since the 1980s with more than 35,000 distinct authors. They estimated that the field is currently growing exponentially, with the number of authors doubling approximately every 8 years. These scholars are undoubtedly using and generating a vast quantity and variety of data and information for both SS research and applications. Unfortunately we know little about what data the SS community is actually using, and whether or not the data that SS scholars generate are being preserved for future use. Moreover, since much SS research is conducted by cross-disciplinary, multi-institutional teams, often scattered around the world, there could well be increased risks of data loss, reduced data quality, inadequate documentation, and poor long-term access and usability. Capabilities and processes therefore need to be established today to support continual, reliable, and efficient preservation of and access to SS data in the future, especially so that they can be reused in conjunction with future data and for new studies not conceived in the original data collection activities. Today's long-term data stewardship challenges include establishing sustainable data governance to facilitate continuing management, selecting data to ensure that limited resources are focused on high priority SS data holdings, securing sufficient rights to allow unforeseen uses, and preparing data to enable use by future communities whose specific research and information needs are not yet known.

    Two decades of epidemiological research shows that silent cerebrovascular disease is common and is associated with future risk for stroke and dementia. It is the most common incidental finding on brain scans. To summarize evidence on the diagnosis and management of silent cerebrovascular disease to prevent stroke, the Stroke Council of the American Heart Association convened a writing committee to evaluate existing evidence, to discuss clinical considerations, and to offer suggestions for future research on stroke prevention in patients with 3 cardinal manifestations of silent cerebrovascular disease: silent brain infarcts, magnetic resonance imaging white matter hyperintensities of presumed vascular origin, and cerebral microbleeds. The writing committee found strong evidence that silent cerebrovascular disease is a common problem of aging and that silent brain infarcts and white matter hyperintensities are associated with future symptomatic stroke risk independently of other vascular risk factors. In patients with cerebral microbleeds, there was evidence of a modestly increased risk of symptomatic intracranial hemorrhage in patients treated with thrombolysis for acute ischemic stroke but little prospective evidence on the risk of symptomatic hemorrhage in patients on anticoagulation. There were no randomized controlled trials targeted specifically to participants with silent cerebrovascular disease to prevent stroke. Primary stroke prevention is indicated in patients with silent brain infarcts, white matter hyperintensities, or microbleeds. Adoption of standard terms and definitions for silent cerebrovascular disease, as provided by prior American Heart Association/American Stroke Association statements and by a consensus group, may facilitate diagnosis and communication of findings from radiologists to clinicians. © 2016 American Heart Association, Inc.

  11. The 'silence' of silent brain infarctions may be related to chronic ischemic preconditioning and nonstrategic locations rather than to a small infarction size

    Full Text Available OBJECTIVE: Silent brain infarctions are the silent cerebrovascular events that are distinguished from symptomatic lacunar infarctions by their 'silence'; the origin of these infarctions is still unclear. This study analyzed the characteristics of silent and symptomatic lacunar infarctions and sought to explore the mechanism of this 'silence'. METHODS: In total, 156 patients with only silent brain infarctions, 90 with only symptomatic lacunar infarctions, 160 with both silent and symptomatic lacunar infarctions, and 115 without any infarctions were recruited. Vascular risk factors, leukoaraiosis, and vascular assessment results were compared. The National Institutes of Health Stroke Scale scores were compared between patients with only symptomatic lacunar infarctions and patients with two types of infarctions. The locations of all of the infarctions were evaluated. The evolution of the two types of infarctions was retrospectively studied by comparing the infarcts on the magnetic resonance images of 63 patients obtained at different times. RESULTS: The main risk factors for silent brain infarctions were hypertension, age, and advanced leukoaraiosis; the main factors for symptomatic lacunar infarctions were hypertension, atrial fibrillation, and atherosclerosis of relevant arteries. The neurological deficits of patients with only symptomatic lacunar infarctions were more severe than those of patients with both types of infarctions. More silent brain infarctions were located in the corona radiata and basal ganglia; these locations were different from those of the symptomatic lacunar infarctions. The initial sizes of the symptomatic lacunar infarctions were larger than the silent brain infarctions, whereas the final sizes were almost equal between the two groups. CONCLUSIONS: Chronic ischemic preconditioning and nonstrategic locations may be the main reasons for the 'silence' of silent brain infarctions.

  12. Reading between eye saccades.

    Full Text Available BACKGROUND: Skilled adult readers, in contrast to beginners, show no or little increase in reading latencies as a function of the number of letters in words up to seven letters. The information extraction strategy underlying such efficiency in word identification is still largely unknown, and methods that allow tracking of the letter information extraction through time between eye saccades are needed to fully address this question. METHODOLOGY/PRINCIPAL FINDINGS: The present study examined the use of letter information during reading, by means of the Bubbles technique. Ten participants each read 5,000 five-letter French words sampled in space-time within a 200 ms window. On the temporal dimension, our results show that two moments are especially important during the information extraction process. On the spatial dimension, we found a bias for the upper half of words. We also show for the first time that letter positions four, one, and three are particularly important for the identification of five-letter words. CONCLUSIONS/SIGNIFICANCE: Our findings are consistent with either a partially parallel reading strategy or an optimal serial reading strategy. We show using computer simulations that this serial reading strategy predicts an absence of a word-length effect for words from four- to seven letters in length. We believe that the Bubbles technique will play an important role in further examining the nature of reading between eye saccades.

    Previous research suggests that being interrupted while reading a text does not disrupt the later recognition or recall of information from that text. This research is used as support for Ericsson and Kintsch's (1995) long-term working memory (LT-WM) theory, which posits that disruptions while reading (e.g., interruptions) do not impair subsequent text comprehension. However, to fully comprehend a text, individuals may need to do more than recognize or recall information that has been presented in the text at a later time. Reading comprehension often requires individuals to connect and synthesize information across a text (e.g., successfully identifying complex topics such as themes and tones) and not just make a familiarity-based decision (i.e., recognition). The goal for this study was to determine whether interruptions while reading disrupt reading comprehension when the questions assessing comprehension require participants to connect and synthesize information across the passage. In Experiment 1, interruptions disrupted reading comprehension. In Experiment 2, interruptions disrupted reading comprehension but not recognition of information from the text. In Experiment 3, the addition of a 15-s time-out prior to the interruption successfully removed these negative effects. These data suggest that the time it takes to process the information needed to successfully comprehend text when reading is greater than that required for recognition. Any interference (e.g., an interruption) that occurs during the comprehension process may disrupt reading comprehension. This evidence supports the need for transient activation of information in working memory for successful text comprehension and does not support LT-WM theory. (c) 2015 APA, all rights reserved).

    Attention plays a critical role in information processing. Its adequate functioning is required for correct development of complex cognitive abilities and regular scholastic progress. Children with attention deficits often have difficulties in reading, writing, and arithmetic. The present study investigated interactions among reading skills, overall scholastic performance as rated by teachers, and components of attention: visual reaction time, simple immediate span of attention, and selectivity. The sample was 98 students in the first and second years of public junior high school (age range 11-14 years, M = 12.6, SD = 1.2), i.e., with expected already well-established reading. Reading was evaluated using Comprehension, Accuracy, and Speed tests. Overall scholastic performance was obtained by means of teachers' ratings. Simple Reaction Time, Digit Span, and Color-Word Interference, included in a multitask computerized test, assessed attention. Analysis confirmed the hypothesis that the reading skills are strongly predictive of the Scholastic Assessment rated by the teachers. High scholastic ratings were correlated with Reading Speed and Accuracy rather than Reading Comprehension. Poor readers showed worse performances on the Digit Span test which measures simple immediate span of attention. Good and poor readers obtained a similar score on the Color-Word Interference task. This observation seems to contrast with the more common interpretation of this effect, suggesting that reading is an automatic process and, therefore, the semantic dimension overcomes the controlled perceptual one. According to other studies, an alternative explanation is suggested. In conclusion, present results confirm the hypothesis of a strong link among reading speed and accuracy, scholastic assessment as rated by teachers, simple immediate span of attention, and visual reaction time.

    Scientists are front and center in quantifying and solving environmental problems. Yet, as a spate of recent news articles in scientific journals point out, much can be done to enhance sustainability within the scientific enterprise itself, particularly by trimming the energy use associated with research facilities and the equipment therein (i,ii,iii, iv). Sponsors of research unwittingly spend on the order of $10 billion each year on energy in the U.S. alone, and the underlying inefficiencies drain funds from the research enterprise while causing 80 MT CO2-equivalent greenhouse-gas emissions (see Box). These are significant sums considering the opportunity costs in terms of the amount of additional research that could be funded and emissions that could be reduced if the underlying energy was used more efficiently. By following commercially proven best practices in facility design and operation, scientists--and the sponsors of science--can cost-effectively halve these costs, while doing their part to put society on alow-carbon diet.

    This study investigated the impact of simulated hyperopic anisometropia and sustained near work on performance of academic-related measures in children. Participants included 16 children (mean age: 11.1 ± 0.8 years) with minimal refractive error. Academic-related outcome measures included a reading test (Neale Analysis of Reading Ability), visual information-processing tests (Coding and Symbol Search subtests from the Wechsler Intelligence Scale for Children), and a reading-related eye movement test (Developmental Eye Movement test). Performance was assessed with and without 0.75 diopters of simulated monocular hyperopic defocus (administered in a randomized order), before and after 20 minutes of sustained near work. Unilateral hyperopic defocus was systematically assigned to either the dominant or nondominant sighting eye to evaluate the impact of ocular dominance on any performance decrements. Simulated hyperopic anisometropia and sustained near work both independently reduced performance on all of the outcome measures (P anisometropia and near work (P anisometropia in combination with sustained near work. Laterality of the refractive error simulation (ocular dominance) did not significantly influence the outcome measures (P > 0.05). A reduction of up to 12% in performance was observed across the range of academic-related measures following sustained near work undertaken during the anisometropic simulation. Simulated hyperopic anisometropia significantly impaired academic-related performance, particularly in combination with sustained near work. The impact of uncorrected habitual anisometropia on academic-related performance in children requires further investigation.

  18. Functionally distinct contributions of the anterior and posterior putamen during sublexical and lexical reading

    Full Text Available Previous studies have investigated orthographic-to-phonological mapping during reading by comparing brain activation for (1 reading words to object naming, or (2 reading pseudowords (e.g. phume to words (e.g. plume. Here we combined both approaches to provide new insights into the underlying neural mechanisms. In fMRI data from 25 healthy adult readers, we first identified activation that was greater for reading words and pseudowords relative to picture and color naming. The most significant effect was observed in the left putamen, extending to both anterior and posterior borders. Second, consistent with previous studies, we show that both the anterior and posterior putamen are involved in articulating speech with greater activation during our overt speech production tasks (reading, repetition, object naming and color naming than silent one-back-matching on the same stimuli. Third, we compared putamen activation for words versus pseudowords during overt reading and auditory repetition. This revealed that the anterior putamen was most activated by reading pseudowords, whereas the posterior putamen was most activated by words irrespective of whether the task was reading words or auditory word repetition. The pseudoword effect in the anterior putamen is consistent with prior studies that associated this region with the initiation of novel sequences of movements. In contrast, the heightened word response in the posterior putamen is consistent with other studies that associated this region with memory guided movement. Our results illustrate how the functional dissociation between the anterior and posterior putamen supports sublexical and lexical processing during reading.

    The purposes of this study were to determine the occurrence of undiagnosed "silent" obstructive sleep apnea (OSA) in dentofacial deformity (DFD) patients at initial surgical presentation and to report on the level of daytime sleepiness in DFD patients with OSA and chronic obstructive nasal breathing (CONB) after undergoing bimaxillary, chin, and intranasal surgery. A retrospective cohort study of patients with a bimaxillary DFD and CONB was implemented. Patients were divided into those with no OSA (group I) and those with OSA (group II). Group II was further subdivided into patients referred with polysomnogram (PSG)-confirmed OSA (group IIa) and those with a diagnosis of OSA only after surgical consultation, airway evaluation, and a positive PSG (group IIb). Group II patients were analyzed at a minimum of 1 year after surgery (range, 1 to 10 years) for daytime sleepiness with the Epworth Sleepiness Scale. Patients with postoperative excessive daytime sleepiness were assessed for risk factors and continued need for OSA treatment. Patients in group II were studied to determine which DFD patterns were most associated with OSA. We compared the prevalence of OSA between our study population and the general population. Two hundred sixty-two patients met the inclusion criteria. Of these, 23% (60 of 262) had PSG-confirmed OSA (group II). This rate was much higher than that found in the general population. Of the patients, 7% (19 of 262) were known to have OSA at initial surgical consultation (group IIa). An additional 16% (41 of 262) were later confirmed by PSG to have OSA (group IIb). Patients with primary mandibular deficiency and short face DFDs were most likely to have OSA (P surgery. A significant association was found between group II patients with postoperative excessive daytime sleepiness ("sleepy" or "very sleepy") and a preoperative body mass index category of overweight (P = .026). Our study found silent OSA to be frequent in the DFD population. The
