  1. Understanding peace a comprehensive introduction

    CERN Document Server

    Fox, Michael Allen

    2013-01-01

    Understanding Peace: A Comprehensive Introduction fills the need for an original, contemporary examination of peace that is challenging, informative, and empowering. This well-researched, fully documented, and highly accessible textbook moves beyond fixation on war to highlight the human capacity for nonviolent cooperation in everyday life and in conflict situations. After deconstructing numerous ideas about war and explaining its heavy costs to humans, animals, and the environment, discussion turns to evidence for the existence of peaceful societies. Further topics include the role of nonviolence in history, the nature of violence and aggression, and the theory and practice of nonviolence. The book offers two new moral arguments against war, and concludes by defining peace carefully from different angles and then describing conditions for creating a culture of peace. Understanding Peace brings a fresh philosophical perspective to discussions of peace, and also addresses down-to-earth issues about effecting ...

    This article hones what is meant by "emergent comprehension". The authors define emergent comprehension as the period when young children, prior to conventional reading, engage in meaningful experiences that stimulate the development and use of meaning-making strategies with potential to affect later reading comprehension. The construct "emergent…

    2017-01-01

    A 48-year-old physical therapist with no history of psychiatric disorders or suicidal tendencies was found dead by his relatives inside his apartment. Multiple stab wounds were present on the chest and the abdomen. Several more superficial cuts were also seen on the neck and the left wrist. At the death scene, there was a large pool of blood in the room, with secondary droplets and stains; a kitchen knife was found beside the body, and a suicide note on a table. Especially the number of wounds raised strong suspicion of a homicide in the first instance but some circumstances (the farewell letter, the absence of clothing injuries, no signs of third-party involvement) and autopsy findings (absence of defense or blunt injuries, the localization of the wounds, the presence of hesitation marks) pointed toward a suicide etiology. Because of the many stab injuries and the lack of a psychiatric history, further forensic investigations were required including a so-called psychological autopsy. This case report highlights that only a comprehensive interpretation of all the elements (circumstances, the scene of death, autopsy findings, and psychological autopsy) can lead to the correct solution of atypical cases of suicide.

    This study examined juvenile justice-involved youths' understanding and appreciation of the Miranda warnings' rights to silence and legal counsel using the Miranda Rights Comprehension Instruments (Goldstein, Zelle, & Grisso, 2012). It also examined the relationships between totality of circumstances factors and understanding and appreciation of rights. Data were collected from 183 youths (140 boys) in pre- and postadjudication facilities in 2 states. Overall, youths demonstrated greater difficulty on measures of appreciation than understanding, with particular deficits in their abilities to comprehend the abstract concept of the right to silence. Results varied slightly by instrument, highlighting the importance of a multimodal assessment of these complex abilities. Examination of totality of circumstances factors identified relationships between some factors (e.g., age, verbal IQ, academic achievement) and Miranda comprehension, but revealed that other factors (e.g., gender, number of previous arrests) were not significantly related to Miranda understanding or appreciation. The findings support a nuanced conceptualization of Miranda rights comprehension that acknowledges the complexity of understanding and appreciating the warnings. Empirical analyses also support the continued use of some totality of circumstances factors and abandonment of others. Findings underscore the necessity of multimodal assessment and interpretation when conducting capacity to waive Miranda rights evaluations. (c) 2015 APA, all rights reserved).

  5. Study on supporting system for operator's comprehensive understanding

    1996-01-01

    Power Reactor and Nuclear Fuel Development Corp. has participated in the development of a system to support the process of operator's plant understanding by the use of information processing techniques such as artificial intelligence since 1994. Analysis and model formation of the process leading to operator's comprehensive understanding of plant (mental model) are undertaken attempting to determine the basic structure of the mental model available for the description of knowledge using the precedent survey and to observe how to utilize operator's own knowledge. After consideration of the way by which plant operators utilize their physical knowledges and the knowledges of physical observation in practice, a basic structure composed of 3 components a qualitative causal network, a hierarchical function model and 3 links joining the two was proposed for the mental model. A questionnaire survey on operator's statements was made and the contents were assigned in several categories for objective analysis. An unified form usable to make a data base was established. Further, we have a plan to develop the first proto-type system to promote operator's understanding by 1998. (M.N.)

    2015-10-01

    We investigated how age and linguistic status affected listeners' ability to follow and comprehend 3-talker conversations, and the extent to which individual differences in language proficiency predict speech comprehension under difficult listening conditions. Younger and older L1s as well as young L2s listened to 3-talker conversations, with or without spatial separation between talkers, in either quiet or against moderate or high 12-talker babble background, and were asked to answer questions regarding their contents. After compensating for individual differences in speech recognition, no significant differences in conversation comprehension were found among the groups. As expected, conversation comprehension decreased as babble level increased. Individual differences in reading comprehension skill contributed positively to performance in younger EL1s and in young EL2s to a lesser degree but not in older EL1s. Vocabulary knowledge was significantly and positively related to performance only at the intermediate babble level. The results indicate that the manner in which spoken language comprehension is achieved is modulated by the listeners' age and linguistic status.

    2012-01-01

    Rules and regulations form the framework of Health Technology Assessments. Legal issues are directly associated with the technology (as patents/licenses) or to the patients and their basic rights (as autonomy). In order to identify the regulations of interest as well as the relevant publications in a systematic and transparent way a specific methodological approach is required. In the absence of adapted methods, our objective was to develop a methodological approach to the systematic retrieval of information on legal issues. No publications on adapted methods could be identified. We therefore developed a procedure following the workflow of information retrieval for effectiveness assessments. This workflow consists of 8 steps: 0. pre-search: identification of the relevant rules, regulations and patient-related issues, 1. translation of the search question, 2. concept building, 3. identification of synonyms, 4. selection of relevant information sources, 5. design of the search strategies, 6. execution and quality check, 7. saving the results and reporting. There are numerous publications on legal issues associated with health technologies. Specifically adapted procedures are qualified to identify them in a systematic and transparent manner using the appropriate sensitivity and precision. A wider application seems to be reasonable in order to further test its practicality against more topics and to modify the proposed method if indicated. Copyright © 2012. Published by Elsevier GmbH.

    2014-09-01

    Prisoners sometimes die in prison, either due to natural illness, violence, suicide, or a result of imprisonment. The purpose of this study is to understand deaths in custody using qualitative methodology and to argue for a comprehensive definition of death in custody that acknowledges deaths related to the prison environment. Interviews were conducted with 33 experts, who primarily work as lawyers or forensic doctors with national and/or international organisations. Responses were coded and analysed qualitatively. Defining deaths in custody according to the place of death was deemed problematic. Experts favoured a dynamic approach emphasising the link between the detention environment and occurrence of death rather than the actual place of death. Causes of deaths and different patterns of deaths were discussed, indicating that many of these deaths are preventable. Lack of an internationally recognised standard definition of death in custody is a major concern. Key aspects such as place, time, and causes of death as well as relation to the prison environment should be debated and incorporated into the definition. Systematic identification of violence within prison institutions is critical and efforts are needed to prevent unnecessary deaths in prison and to protect vulnerable prisoners.

    Pelletier, Janette; Beatty, Ruth

    2015-01-01

    Two studies examined children's developing understanding of Aesop's fables in relation to reading comprehension and to theory of mind. Study 1 included 172 children from Junior Kindergarten through Grade 6 in a school-wide examination of the relation between reading comprehension skills and understanding of Aesop's fables told orally. Study 2 examined the relation between theory of mind and fables understanding among 186 Junior (4-year-old) and Senior (5-year-old) Kindergarten children. Study 1 results showed a developmental progression in fables understanding with children's responses becoming increasingly decontextualized as they were able to extract the life lesson. After general vocabulary, passage comprehension predicted fables understanding. Study 2 results showed a relation between young children's theory of mind development and their understanding of fables. After general vocabulary, second-order theory of mind predicted children's fables understanding. Findings point to the importance of developing mental state awareness in children's ability to judge characters' intentions and to understand the deeper message embedded in fables.

  13. Coping with violence: a comprehensive framework and implications for understanding resilience.

    Boxer, Paul; Sloan-Power, Elizabeth

    2013-07-01

    Interpersonal violence is present at all levels of influence in the social ecology and can have comprehensive and devastating effects on child and adolescent development through multiple simultaneous channels of exposure. Children's experiences with violence have been linked with a range of behavioral and mental health difficulties including posttraumatic stress disorder and aggressive behavior. In this article, we offer a conceptual framework delineating the ways in which children and adolescents might encounter violence, and a theoretical integration describing how violence might impact mental and behavioral health outcomes through short- and long-term processes. We propose that coping reactions are fundamental to the enduring effects of violence exposure on their psychosocial development and functioning. Finally, we discuss the manner in which coping efforts can support resilience among children exposed to violence and suggest new directions for research and preventive intervention aimed at optimizing outcomes for children at risk of exposure.

    2014-09-01

    This paper describes the theoretical framework, as well as the development and testing of the intervention, Comprehension Tools for Teachers (CTT), which is composed of eight component interventions targeting malleable language and reading comprehension skills that emerging research indicates contribute to proficient reading for understanding for prekindergarteners through fourth graders. Component interventions target processes considered largely automatic as well as more reflective processes, with interacting and reciprocal effects. Specifically, we present component interventions targeting cognitive, linguistic, and text-specific processes, including morphological awareness, syntax, mental-state verbs, comprehension monitoring, narrative and expository text structure, enacted comprehension, academic knowledge, and reading to learn from informational text. Our aim was to develop a tool set composed of intensive meaningful individualized small group interventions. We improved feasibility in regular classrooms through the use of design-based iterative research methods including careful lesson planning, targeted scripting, pre- and postintervention proximal assessments, and technology. In addition to the overall framework, we discuss seven of the component interventions and general results of design and efficacy studies.

    Full Text Available Currently, there is no single test for multiple sclerosis (MS. Diagnosis is confirmed through clinical evaluation, abnormalities revealed by magnetic resonance imaging (MRI, and analysis of cerebrospinal fluid (CSF chemistry. The early and accurate diagnosis of the disease, monitoring of progression, and gauging of therapeutic intervention are important but elusive elements of patient care. Moreover, a deeper understanding of the disease pathology is needed, including discovery of accurate biomarkers for MS. Herein we review putative biomarkers of MS relating to neurodegeneration and contributions to neuropathology, with particular focus on autoimmunity. In addition, novel assessments of biomarkers not driven by hypotheses are discussed, featuring our application of advanced proteomics and metabolomics for comprehensive phenotyping of CSF and blood. This strategy allows comparison of component expression levels in CSF and serum between MS and control groups. Examination of these preliminary data suggests that several CSF proteins in MS are differentially expressed, and thus, represent putative biomarkers deserving of further evaluation.

  17. CEOS Theory: A Comprehensive Approach to Understanding Hard to Maintain Behaviour Change.

    Science.gov (United States)

    Borland, Ron

    2017-03-01

    This paper provides a brief introduction to CEOS theory, a comprehensive theory for understanding hard to maintain behaviour change. The name CEOS is an acronym for Context, Executive, and Operational Systems theory. Behaviour is theorised to be the result of the moment by moment interaction between internal needs (operational processes) in relation to environmental conditions, and for humans this is augmented by goal-directed, executive action which can transcend immediate contingencies. All behaviour is generated by operational processes. Goal-directed behaviours only triumph over contingency-generated competing behaviours when operational processes have been sufficiently activated to support them. Affective force can be generated around executive system (ES) goals from such things as memories of direct experience, vicarious experience, and emotionally charged communications mediated through stories the person generates. This paper makes some refinements and elaborations of the theory, particularly around the role of feelings, and of the importance of stories and scripts for facilitating executive action. It also sketches out how it reconceptualises a range of issues relevant to behaviour change. CEOS provides a framework for understanding the limitations of both informational and environmental approaches to behaviour change, the need for self-regulatory strategies and for taking into account more basic aspects of human functioning. © 2016 The Authors.

    Traditional mental health models focus on psychological problems and distress; accordingly, health is viewed as the absence of illness or disability. In contrast, a dual-factor model of mental health incorporates both indicators of positive subjective well-being (SWB) and measures of psychopathological symptoms to comprehensively determine an individual's psychological adjustment. This study used such a dual-factor model to measure the mental health status of young adolescents. A total of 764 middle school students were classified into one of four distinct groups based on having high or low psychopathology and high or low SWB. Furthermore, group differences in student engagement, academic achievement, and environmental support for learning were investigated. Results demonstrated the existence of a traditionally neglected group of adolescents (low SWB and low psychopathology) who are nonetheless at risk for academic and behavior problems in school and who performed no better than the most troubled group of adolescents. Overall, both the presence of positive well-being and the absence of symptoms were necessary for ensuring the most advantageous school performance. These results highlight the importance of incorporating positive indicators of well-being along with traditional negative factors in more fully understanding relationships between individuals' mental health and educational outcomes. © 2010 American Orthopsychiatric Association.

    In the present study we provide thorough descriptions of two children with a semantic-pragmatic disorder, a subgroup within the group of specific and severe developmental language disorders, from a neurolinguistic and interactional perspective. We argue that the pragmatic problems, at least in these two girls, are most probably secondary to their semantic/conceptual deficit. If sufficient contextual cues are provided comprehension is improved and, as a consequence, the pragmatic problems are reduced.

  6. Comprehensive Understanding of Ductility Loss Mechanisms in Various Steels with External and Internal Hydrogen

    2017-11-01

    Hydrogen-induced ductility loss and related fracture morphologies are comprehensively discussed in consideration of the hydrogen distribution in a specimen with external and internal hydrogen by using 300-series austenitic stainless steels (Types 304, 316, 316L), high-strength austenitic stainless steels (HP160, XM-19), precipitation-hardened iron-based super alloy (A286), low-alloy Cr-Mo steel (JIS-SCM435), and low-carbon steel (JIS-SM490B). External hydrogen is realized by a non-charged specimen tested in high-pressure gaseous hydrogen, and internal hydrogen is realized by a hydrogen-charged specimen tested in air or inert gas. Fracture morphologies obtained by slow-strain-rate tensile tests (SSRT) of the materials with external or internal hydrogen could be comprehensively categorized into five types: hydrogen-induced successive crack growth, ordinary void formation, small-sized void formation related to the void sheet, large-sized void formation, and facet formation. The mechanisms of hydrogen embrittlement are broadly classified into hydrogen-enhanced decohesion (HEDE) and hydrogen-enhanced localized plasticity (HELP). In the HEDE model, hydrogen weakens interatomic bonds, whereas in the HELP model, hydrogen enhances localized slip deformations. Although various fracture morphologies are produced by external or internal hydrogen, these morphologies can be explained by the HELP model rather than by the HEDE model.

  7. Linguistic inter-understanding gives evidence in favor of the mental models theory: Induction and comprehension

    Directory of Open Access Journals (Sweden)

    Miguel López-Astorga

    2017-08-01

    Full Text Available Linguistic inter-understanding is a communicative phenomenon that is well known and that has been studied in detail. It basically consists of the fact that an individual speaking a language is able to understand another person speaking a different language, and this without deeply knowing this last language or being able to express himself/herself in it. The phenomenon, which is especially frequent in the case of very similar languages, occurs because of certain inferential processes that can happen in the human mind when people try to interpret information in a distinct language. In this way, the main aim of this paper is to show how such processes are very akin to some of those that the mental models theory attributes to the human reasoning ability, and that hence linguistic inter-understanding can be considered as evidence that this last theory is, at least partially, correct.

    2014-01-01

    Although performance on laboratory-based implicit bias tasks often is interpreted strictly in terms of the strength of automatic associations, recent evidence suggests that such tasks are influenced by higher-order cognitive control processes, so-called executive functions (EFs). However, extant work in this area has been limited by failure to account for the unity and diversity of EFs, focus on only a single measure of bias and/or EF, and relatively small sample sizes. The current study sought to comprehensively model the relation between individual differences in EFs and the expression of racial bias in three commonly used laboratory measures. Participants (N=485) completed a battery of EF tasks (session 1) and three racial bias tasks (session 2), along with numerous individual difference questionnaires. The main findings were as follows: (1) measures of implicit bias were only weakly intercorrelated; (2) EF and estimates of automatic processes both predicted implicit bias and also interacted, such that the relation between automatic processes and bias expression was reduced at higher levels of EF; (3) specific facets of EF were differentially associated with overall task performance and controlled processing estimates across different bias tasks; (4) EF did not moderate associations between implicit and explicit measures of bias; and (5) external, but not internal, motivation to control prejudice depended on EF to reduce bias expression. Findings are discussed in terms of the importance of global and specific EF abilities in determining expression of implicit racial bias. PMID:25603372

  13. Understanding plant cellulose synthases through a comprehensive investigation of the cellulose synthase family sequences.

    Andrew eCarroll

    2011-03-01

    Full Text Available The development of cellulose as an organizing structure in the plant cell wall was a key event in both the initial colonization and the subsequent domination of the terrestrial ecosystem by vascular plants. A wealth of experimental data has demonstrated the complicated genetic interactions required to form the large synthetic complex that synthesizes cellulose. However, these results are lacking an extensive analysis of the evolution, specialization, and regulation of the proteins that compose this complex. Here we perform an in-depth analysis of the sequences in the cellulose synthase (CesA family. We investigate the phylogeny of the CesA family, with emphasis on evolutionary specialization. We define specialized subfamilies and identify the class-specific regions within the CesA sequence that may explain this specialization. We investigate changes in regulation of CesAs by looking at the conservation of proposed phosphorylation sites. We investigate the conservation of sites where mutations have been documented that impair cellulose synthase function, and compare these sites to those observed in the closest cellulose synthase-like (Csl families to better understand what regions may separate the CesAs from other Csls. Finally we identify two positions with strong conservation of the aromatic trait, but lacking conservation of amino acid identity, which may represent residues important for positioning the sugar substrate for catalysis. These analyses provide useful tools for understanding characterized mutations and post-translational modifications, and for informing further experiments to probe CesA assembly, regulation, and function through site-directed mutagenesis or domain swapping experiments.

    The development of cellulose as an organizing structure in the plant cell wall was a key event in both the initial colonization and the subsequent domination of the terrestrial ecosystem by vascular plants. A wealth of experimental data has demonstrated the complicated genetic interactions required to form the large synthetic complex that synthesizes cellulose. However, these results are lacking an extensive analysis of the evolution, specialization, and regulation of the proteins that compose this complex. Here we perform an in-depth analysis of the sequences in the cellulose synthase (CesA) family. We investigate the phylogeny of the CesA family, with emphasis on evolutionary specialization. We define specialized clades and identify the class-specific regions within the CesA sequence that may explain this specialization. We investigate changes in regulation of CesAs by looking at the conservation of proposed phosphorylation sites. We investigate the conservation of sites where mutations have been documented that impair CesA function, and compare these sites to those observed in the closest cellulose synthase-like (Csl) families to better understand what regions may separate the CesAs from other Csls. Finally we identify two positions with strong conservation of the aromatic trait, but lacking conservation of amino acid identity, which may represent residues important for positioning the sugar substrate for catalysis.

  15. Kant, Xunzi and the Artificiality of Manners

    2017-01-01

    Full Text Available Both Chinese and Western philosophers have argued for the ethical importance of manners. Their approaches are sometimes criticized on the grounds that manners are artificial. I compare Xunzi’s and Kant’s responses to this claim, and discuss the relevance of both positions for the development of a theory of manners. I show that there is no single artificiality claim, but rather four different claims: the claim that polite behavior lacks spontaneity, the claim that it is insincere, the claim that it goes against human nature, and the claim that it is arbitrary. While Kant is mainly concerned with the insincerity claim, Xunzi focusses on the claim that manners are arbitrary rules. Because of their different understandings of the function of manners both authors only provide a partial answer to the artificiality claim. To arrive at a full account of manners both perspectives must be combined.

  16. What the comprehensive economics of blindness and visual impairment can help us understand

    Full Text Available Since the year 2000, the amount written about the economics of blindness and visual impairment has increased substantially. In some cases, the studies listed under this heading are calculations of the costs related to vision impairment and blindness at a national or global level; in other cases the studies examine the cost-effectiveness of strategies to prevent or modify visual impairment or blindness that are intended to be applied as a guide to treatment recommendations and coverage decisions. In each case the references are just examples of many that could be cited. These important studies have helped advocates, policy makers, practitioners, educators, and others interested in eye and vision health to understand the magnitude of the impact that visual impairment and blindness have on the world, regions, nations, and individuals and the tradeoffs that need to be made to limit the impact. However, these studies only begin to tap into the insights that economic logic might offer to those interested in this field. This paper presents multiple case studies that demonstrate that the economics of blindness and visual impairment encompasses much more than simply measures of the burden of the condition. Case studies demonstrating the usefulness of economic insight include analysis of the prevention of conditions that lead to impairment, decisions about refractive error and presbyopia, decisions about disease and injury treatment, decisions about behavior among those with uncorrectable impairment, and decisions about how to regulate the market all have important economic inputs.

    It seems important to consider students' attitudes towards physical education (PE), and the way they learn sports. The present study examines students' perceptions of motivation and achievement in PE after experiencing three consecutive sport units. Two hundred and thirty seven students from the 1st, 2nd, 3rd, and 4th grade in a high school in Burgos (Spain) and two teachers agreed to participate. They were divided into two groups in order to compare two instructional approaches. The experimental group (A), 128 students, experienced Teaching Games for Understanding (TGfU), while the control group (B), 109 students, experienced a technical-traditional approach. Each group was taught by a different teacher. The study followed a mixed-method research design with quantitative (questionnaire) and qualitative (interview) data. Results revealed that group A showed greater motivation and achievement in PE than group B. Significant differences were found in achievement. Participants with better academic results in group A were more positive in sport participation. Meanwhile, students who practiced more extracurricular sports in group B were more actively involved in sport. Teachers disagreed greatly on the way sport should be taught in PE.

  18. A Comprehensive Understanding of Machine and Material Behaviors During Inertia Friction Welding

    Science.gov (United States)

    Tung, Daniel J.

    Inertia Friction Welding (IFW), a critical process to many industries, currently relies on trial-and-error experimentation to optimize process parameters. Although this Edisonian approach is very effective, the high time and dollar costs incurred during process development are the driving force for better design approaches. Thermal-stress finite element modeling has been increasingly used to aid in process development in the literature; however, several fundamental questions on machine and material behaviors remain unanswered. The work presented here aims produce an analytical foundation to significantly reduce the costly physical experimentation currently required to design the inertia welding of production parts. Particularly, the work is centered around the following two major areas. First, machine behavior during IFW, which critically determines deformation and heating, had not been well understood to date. In order to properly characterize the IFW machine behavior, a novel method based on torque measurements was invented to measure machine efficiency, i.e. the ratio of the initial kinetic energy of the flywheel to that contributing to workpiece heating and deformation. The measured efficiency was validated by both simple energy balance calculations and more sophisticated finite element modeling. For the first time, the efficiency dependence on both process parameters (flywheel size, initial rotational velocity, axial load, and surface roughness) and materials (1018 steel, Low Solvus High Refractory LSHR and Waspaloy) was quantified using the torque based measurement method. The effect of process parameters on machine efficiency was analyzed to establish simple-to-use yet powerful equations for selection and optimization of IFW process parameters for making welds; however, design criteria such as geometry and material optimization were not addressed. Second, there had been a lack of understanding of the bond formation during IFW. In the present research, an

  20. Emergency management: does it have a sufficiently comprehensive understanding of decision-making, process and context?

    Niculae, C.

    2003-01-01

    Full text: It is now widely recognized in the social and management sciences that the effective support of decision-making requires a multi-disciplinary perspective, with businesses increasingly using inter-disciplinary teams. This trend is also seen in nuclear emergency management, for example in the UK inter-disciplinary groups are formed to focus on specific topics such as remediation where their recommendations are feed to the decision makers. The necessity of taking a multi-disciplinary perspective is particularly important for contexts in which the decision makers are likely to be under high stress and so could revert to instinctive patterns of behaviour and modes of communication found in their core disciplines. Yet when we look at the design of the information systems produced to support emergency management, we find a very partial set of disciplinary perspectives providing a strongly rationalistic, technocratic view. These systems have been developed by the technical community with little consultation with non-expert decision makers and limited understanding of emergency management processes across Europe and the social systems with which they interact. In this paper we have considered the Cynefin model, developed by IBM, which draws together much of the work on decision making and decision context over the past 30-40 years, describing the possible contexts in which decision-making may take place, the known, the knowable, the complex and the chaotic space. The known space is the realm of scientific knowledge where the cause and effect are understood. Next, there is the knowable space the realm of scientific enquiry where the cause and effect can be determined with sufficient data. In the complex space there are many interacting cause and effects, to the extent that we do not have sufficiently refined models to predict what will happen as a consequence of any particular actions and the cause and effect may only be explained after the event.

  1. Molecular phenology in plants: in natura systems biology for the comprehensive understanding of seasonal responses under natural environments.

    Phenology refers to the study of seasonal schedules of organisms. Molecular phenology is defined here as the study of the seasonal patterns of organisms captured by molecular biology techniques. The history of molecular phenology is reviewed briefly in relation to advances in the quantification technology of gene expression. High-resolution molecular phenology (HMP) data have enabled us to study phenology with an approach of in natura systems biology. I review recent analyses of FLOWERING LOCUS C (FLC), a temperature-responsive repressor of flowering, along the six steps in the typical flow of in natura systems biology. The extensive studies of the regulation of FLC have made this example a successful case in which a comprehensive understanding of gene functions has been progressing. The FLC-mediated long-term memory of past temperatures creates time lags with other seasonal signals, such as photoperiod and short-term temperature. Major signals that control flowering time have a phase lag between them under natural conditions, and hypothetical phase lag calendars are proposed as mechanisms of season detection in plants. Transcriptomic HMP brings a novel strategy to the study of molecular phenology, because it provides a comprehensive representation of plant functions. I discuss future perspectives of molecular phenology from the standpoints of molecular biology, evolutionary biology and ecology. © 2015 The Author. New Phytologist © 2015 New Phytologist Trust.

  2. Toward a better understanding of the mechanisms of symbiosis: a comprehensive proteome map of a nascent insect symbiont

    Full Text Available Symbiotic bacteria are common in insects and can affect various aspects of their hosts’ biology. Although the effects of insect symbionts have been clarified for various insect symbiosis models, due to the difficulty of cultivating them in vitro, there is still limited knowledge available on the molecular features that drive symbiosis. Serratia symbiotica is one of the most common symbionts found in aphids. The recent findings of free-living strains that are considered as nascent partners of aphids provide the opportunity to examine the molecular mechanisms that a symbiont can deploy at the early stages of the symbiosis (i.e., symbiotic factors. In this work, a proteomic approach was used to establish a comprehensive proteome map of the free-living S. symbiotica strain CWBI-2.3T. Most of the 720 proteins identified are related to housekeeping or primary metabolism. Of these, 76 were identified as candidate proteins possibly promoting host colonization. Our results provide strong evidence that S. symbiotica CWBI-2.3T is well-armed for invading insect host tissues, and suggest that certain molecular features usually harbored by pathogenic bacteria are no longer present. This comprehensive proteome map provides a series of candidate genes for further studies to understand the molecular cross-talk between insects and symbiotic bacteria.

  3. Understanding the Mechanisms behind Changing People’s Recycling Behavior at Work by Applying a Comprehensive Action Determination Model

    Sunita Prugsamatz Ofstad

    2017-02-01

    Full Text Available This study moves toward a better understanding of the mechanisms behind changing people’s recycling behavior at work by mapping out which pathways and variables change in recycling behavior as triggered by interventions. A questionnaire was designed based on the theory of planned behaviour, the norm-activation model, habits, and a comprehensive action determination model (CADM. The data was collected in two rounds: before the intervention and after a three-month pilot period with implemented interventions using a sample of n = 1269 students and employees. The CADM model appears to be a good fit with the data. The results from the structural equation modelling indicate the pathways to influencing behavioural change. The most important psychological variables accounting for waste separation behaviour are intentions, perceived behavioural control, personal norms, social norms and habits. No difference in waste separation behaviour was observed in the control building. Interventions targeting the increase in waste separation raised participants’ intentions to engage in such behaviour. Results indicate that waste separation at work must go beyond technical aspects to include various key elements of sustainability to ensure success. Furthermore, understanding human behavior is key in determining the performance and success of an integrated and effective recycling intervention strategy.

    Ticks are obligate hematophagous arthropods of significant importance to human and veterinary medicine. They transmit a vast array of pathogens, including bacteria, viruses, protozoa, and helminths. Most epidemiological data on ticks and tick-borne pathogens (TBPs) in the West Indies are limited to common livestock pathogens such as Ehrlichia ruminantium, Babesia spp. (i.e., B. bovis and B. bigemina ), and Anaplasma marginale , and less information is available on companion animal pathogens. Of note, human tick-borne diseases (TBDs) remain almost completely uncharacterized in the West Indies. Information on TBP presence in wildlife is also missing. Herein, we provide a comprehensive review of the ticks and TBPs affecting human and animal health in the Caribbean, and introduce the challenges associated with understanding TBD epidemiology and implementing successful TBD management in this region. In particular, we stress the need for innovative and versatile surveillance tools using high-throughput pathogen detection (e.g., high-throughput real-time microfluidic PCR). The use of such tools in large epidemiological surveys will likely improve TBD prevention and control programs in the Caribbean.

    Well-defined polyacrylonitriles (PANs) with different molecular weights were synthesized through an activator regenerated by electron-transfer atom-transfer radical polymerization method and employed as binders in silicon negative electrode for lithium-ion batteries. Compared with poly(vinylidene fluoride) and carboxyl methyl cellulose as binders, the electrode performance of PANs is well-improved. Specifically, at 100 mA g(-1) from 0.01 to 1.5 V, the initial discharge capacity of PAN100-based electrode is 4147.8 mA h g(-1) and still remains about 1639.6 mA h g(-1) over 50 cycles. A comprehensive understanding on the improvement mechanism is preliminarily discussed. The results indicate that the superior performance largely depends on the higher lithium ion diffusion efficiency in PAN which results from the weak interaction between lithium ions and PAN polymer chain, and the hydrogen bonds among the nitrile group (C≡N) of PAN, Si nanoparticles, and the current collector, which will lead to an efficient coating of PAN with the Si particles and well-improved adhesion strength, synergistically depressing the structural deterioration of silicon electrodes.

    The purpose of this study was to investigate the joint and unique contributions of morphological awareness and vocabulary knowledge at five reading comprehension levels in adult basic education (ABE) students. We introduce the statistical technique of multiple quantile regression, which enabled us to assess the predictive utility of morphological awareness and vocabulary knowledge at multiple points (quantiles) along the continuous distribution of reading comprehension. To demonstrate the efficacy of our multiple quantile regression analysis, we compared and contrasted our results with a traditional multiple regression analytic approach. Our results indicated that morphological awareness and vocabulary knowledge accounted for a large portion of the variance (82%-95%) in reading comprehension skills across all quantiles. Morphological awareness exhibited the greatest unique predictive ability at lower levels of reading comprehension whereas vocabulary knowledge exhibited the greatest unique predictive ability at higher levels of reading comprehension. These results indicate the utility of using multiple quantile regression to assess trajectories of component skills across multiple levels of reading comprehension. The implications of our findings for ABE programs are discussed. © Hammill Institute on Disabilities 2014.

    How do people make sense of the sequential images in visual narratives like comics? A growing literature of recent research has suggested that this comprehension involves the interaction of multiple systems: The creation of meaning across sequential images relies on a "narrative grammar" that packages conceptual information into categorical roles organized in hierarchic constituents. These images are encapsulated into panels arranged in the layout of a physical page. Finally, how panels frame information can impact both the narrative structure and page layout. Altogether, these systems operate in parallel to construct the Gestalt whole of comprehension of this visual language found in comics.

    2014-08-01

    Dyslexia is associated with difficulties in language-specific skills such as spelling, writing and reading; the difficulty in acquiring literacy skills is not a result of low intelligence or the absence of learning opportunity, but these issues will persist throughout life and could affect long-term education. Writing is a complex process involving many different functions, integrated by the working memory system; people with dyslexia have a working memory deficit, which means that concentration on writing quality may be detrimental to understanding. We confirm impaired working memory in a sample of university students with (compensated) dyslexia, and using a within-subject design with three test conditions, we show that these participants demonstrated better understanding of a piece of text if they had used automatic spelling correction software during a dictation/transcription task. We hypothesize that the use of the autocorrecting software reduced demand on working memory, by allowing word writing to be more automatic, thus enabling better processing and understanding of the content of the transcriptions and improved recall. Long-term and regular use of autocorrecting assistive software should be beneficial for people with and without dyslexia and may improve confidence, written work, academic achievement and self-esteem, which are all affected in dyslexia.

  19. Towards a more comprehensive understanding of the diabatic ABL dynamics: variability of the pressure gradient in time and height

    Momen, M.; Bou-Zeid, E.

    2016-12-01

    Real-world atmospheric and oceanic boundary layers involve many inherent complexities that have often been neglected in the previous studies. For example, pressure gradients in nature frequently vary with time (unsteadiness) and height (baroclinicity); yet most previous investigations have focused on the steady-state barotropic conditions. We perform a suite of large-eddy simulations (LES), which include the temporal/spatial variability of the pressure gradient in the presence of the surface buoyancy. The impact of the variations in the pressure gradient on the mean and turbulent production, dissipation, and transport terms will be presented (e.g. figure 1). We then show that the mean ABL dynamics can be interpreted as a damped oscillator where inertial, Coriolis, and friction forces reflect the mass, spring and damper respectively (see e.g. Momen and Bou-Zeid [1]). This simplified physical framework reduces the governing RANS PDEs into a single ODE. The surface buoyancy forces largely influence the damping term in the model, corresponding to friction forces. The height dependence of the pressure gradient appears as an independent parameter in the model and hence this model can also be used to predict such conditions with an appropriate selection of the corresponding forces. The performance of this model is validated against LES results. The performed simulations help us better understand and model the underlying physics of the real ABLs. In addition to elucidating the fundamental features of the diurnal cycle and low-level jets, the reduced model covers a much wider range of realistic conditions, and can be employed for short-term forecasts of wind power production, and in various other engineering and meteorological applications.

Results Here, we present miRTrail, an integrative tool that allows for performing comprehensive analyses of interactions of genes and miRNAs based on expression profiles. The integrated analysis of mRNA and miRNA data should generate more robust and reliable results on deregulated pathogenic processes and may also offer novel insights into the regulatory interactions between miRNAs and genes. Our web-server excels in carrying out gene sets analysis, analysis of miRNA sets as well as the combination of both in a systems biology approach. To this end, miRTrail integrates information on 20.000 genes, almost 1.000 miRNAs, and roughly 280.000 putative interactions, for Homo sapiens and accordingly for Mus musculus and Danio rerio. The well-established, classical Chi-squared test is one of the central techniques of our tool for the joint consideration of miRNAs and their targets. For interactively visualizing obtained results, it relies on the network analyzers and viewers BiNA or Cytoscape-web, also enabling direct access to relevant literature. We demonstrated the potential of miRTrail by applying our tool to mRNA and miRNA data of malignant melanoma. MiRTrail identified several deregulated miRNAs that target deregulated mRNAs including miRNAs hsa-miR-23b and hsa-miR-223, which target the highest numbers of deregulated mRNAs and regulate the pathway "basal cell carcinoma". In addition, both miRNAs target genes like PTCH1 and RASA1 that are involved in many oncogenic processes. Conclusions The application

    Full Text Available Background: Patient information may assist in promoting shared decision-making, however it is imperative that the information presented is comprehensible and acceptable to the target audience. Objective: This study sought to explore the acceptability and comprehensibility of the ‘Medicines in Scotland: What’s the right treatment for you?’ factsheet to the general public. Methods: Qualitative semi-structured telephone interviews were conducted with members of the public. An interview schedule was developed to explore the acceptability and comprehensibility of the factsheet. Participants were recruited by a researcher who distributed information packs to attendees (n=70 of four community pharmacies. Interviews, (12-24 minutes duration, were audio recorded, transcribed verbatim and analysed using a framework approach. Results: Nineteen participants returned a consent form (27.1%, twelve were interviewed. Six themes were identified: formatting of the factsheet and interpretation; prior health knowledge and the factsheet; information contained in the factsheet; impact of the factsheet on behaviour; uses for the factsheet; and revisions to the factsheet. Conclusions: The factsheet was generally perceived as helpful and comprehensive. It was highlighted that reading the leaflet may generate new knowledge and may have a positive impact on behaviour.

    Full Text Available Interaction between tertiary educators and students, we contend, improves trust and betters student responses to emotional distress while at university. Therefore, we introduce the “Deskside Manner Framework” as an emerging practice in the tertiary teaching and learning context to aid student transition success. Based on concepts and practice that originated primarily in the medical profession and later in other high credence professional contexts, the deskside manner framework includes: show respect, critical listening, the four Bs and follow up. Deskside manner is transferrable and we aim to facilitate it through workshops and by developing a digital repository of educator-student interaction stories.  

  8. Institutional traditions in teachers' manners of teaching

    Lundqvist, Eva; Almqvist, Jonas; Östman, Leif

    2012-03-01

    The aim of this article is to make a close case study of one teacher's teaching in relation to established traditions within science education in Sweden. The teacher's manner of teaching is analysed with the help of an epistemological move analysis. The moves made by the teacher are then compared in a context of educational philosophy and selective tradition. In the analyses the focus is to study the process of teaching and learning in action in institutionalised and socially shared practices. The empirical material consists of video recordings of four lessons with the same group of students and the same teacher. The students are all in Year 7 in a Swedish 9-year compulsory school. During these lessons the students work with a subject area called "Properties of materials". The results show that the teacher makes a number of different moves with regard to how to proceed and come to a conclusion about what the substances are. Many of these moves are special in that they indicate that the students need to be able to handle the procedural level of school science. These moves do not deal directly with the knowledge production process, but with methodological aspects. The function of the moves turns the students' attention from one source of knowledge to another. The moves are aimed at helping the students to help themselves, since it is through their own activity and their own thinking that learning takes place. This is characteristic in the teacher's manner of teaching. When compared in a context of educational philosophy, this manner of teaching has similarities with progressentialism; a mixture of essentialism and progressivism. This educational philosophy is a central aspect of what is called the academic tradition—a selective tradition common in science education in Sweden between 1960 and 1990.

  9. Embodied understanding.

    Science.gov (United States)

    Johnson, Mark

    2015-01-01

    Western culture has inherited a view of understanding as an intellectual cognitive operation of grasping of concepts and their relations. However, cognitive science research has shown that this received intellectualist conception is substantially out of touch with how humans actually make and experience meaning. The view emerging from the mind sciences recognizes that understanding is profoundly embodied, insofar as our conceptualization and reasoning recruit sensory, motor, and affective patterns and processes to structure our understanding of, and engagement with, our world. A psychologically realistic account of understanding must begin with the patterns of ongoing interaction between an organism and its physical and cultural environments and must include both our emotional responses to changes in our body and environment, and also the actions by which we continuously transform our experience. Consequently, embodied understanding is not merely a conceptual/propositional activity of thought, but rather constitutes our most basic way of being in, and engaging with, our surroundings in a deep visceral manner.

    Miftachul Huda

    2016-11-01

    Full Text Available This article examines the requirements for quality learning in Islam from the perspective of al-Zarnūjī and according to his book, Ta‘līm al-Muta‘allim. This book has been a source of reference for both students and teachers in many educational institutions in Muslim countries, particularly, the Islamic boarding schools in Indonesia. The article attempts to understand the students’ learning requirements proposed by al-Zarnūjī in the above treatise. It is, therefore, a library-based research. The research tackles many issues. It addresses the need for a broad-based learning process and analyzes the requirements in the light of the modern day learning circumstances. It was found that al-Zarnūjī’s theory of quality learning is conditional on six main principles which are, indeed, determinants of quality student outcomes. These are intelligence or high learning ability; high motivation for learning; patience, emotional stability, and commitment to the learning process; availability of financial support; inspiration of the teachers; and disposition to time management in the learning process. The notion of quality education is fundamental to the classical perspective of learning in Islam.

    Michael Plomer

    2010-09-01

    Full Text Available The learning outcome of a physics laboratory course for medical students was examined in an interdisciplinary field study and discussed for the electrical physiology (“Propagation of Excitation and Nerve Cells”. At the Ludwig-Maximilians-University of Munich (LMU at a time about 300 medicine students were assessed in two successive years. Students from the control group worked with standard experiments, while students from the treatment group performed newly developed “addressee-specific” experiments, designed to guide students to transfer physics knowledge to physiological problems. The assessment took place within the laboratory course on physiology, after the students had finished their laboratory classes in physics, and consisted of the construction of a concept map with additional multiple choice questions. The results showed that standard physics experiments are not adequate for teaching students to transfer physical principles to physiology. Introducing new addressee-specific experiments enriched the physics laboratory course by improving student attitudes toward physics and demonstrating better ability of students to relate concepts of physics and medicine, and overall to improve their understanding of the physics taught in the course.

    2017-07-01

    Complex non-communicable diseases (NCDs), including cancer, cardiovascular disease, obesity, diabetes, and chronic respiratory disorders, are major causes of morbidity and mortality globally. The complexity of NCDs requires innovative, integrated, and interdisciplinary approaches for diagnosis, treatment, and prevention by adopting the new paradigm called systems medicine. A growing body of evidence suggests that sexual dysfunction in general and erectile and lubrication dysfunctions in particular are, in a sex-dependent manner, efficient predictors of overall systemic well-being. However, the relation between systems medicine and sexual medicine is not well defined. To demonstrate that in combating the major NCDs, sexual health can be used as a surrogate marker of systemic health and can facilitate the diagnosis, treatment, and prevention of NCDs. A comprehensive review of peer-reviewed publications on the topic was performed through a PubMed search. Because there is a strong biological basis for the developmental origins of health and disease not only in the early phases of development but also later in life, the identification of appropriate biomarkers is essential for monitoring these timelines and trajectories for better understanding NCD processes, risk stratification for NCD intervention, and prevention. In this review, I propose a novel approach in which sexual medicine can be used as a new tool to understand and manage NCDs and as a marker of systemic health. Moreover, the multipronged application of systems medicine to pathophysiologic changes leading to sexual dysfunction might sustain the growth of a young science such as sexual medicine. This multilevel approach has the potential to suggest novel avenues for the comprehensive management of NCDs and sexual dysfunction in a sex-dependent manner. Jannini EA.

  15. Language Games and Musical Understanding

    Directory of Open Access Journals (Sweden)

    Alessandro Arbo

    2013-05-01

    Full Text Available Wittgenstein has often explored language games that have to do with musical objects of different sizes (phrases, themes, formal sections or entire works. These games can refer to a technical language or to common parlance and correspond to different targets. One of these coincides with the intention to suggest a way of conceiving musical understanding. His model takes the form of the invitation to "hear (something as (something": typically, to hear a musical passage as an introduction or as a conclusion or in a certain tonality. However one may ask to what extent or in what terms (literal or metaphorical these procedures, and usually the intervention of language games, is requested by our common ways of understanding music. This article shows through the use of some examples that aspectual perception inherent to musical understanding does not require language games as a necessary condition (although in many cases the link between them seems very strong, in contradiction with the thesis of an essential linguistic character of music. At a basic level, it seems more appropriate to insist on the notion of a game: to understand music means to enter into the orbit of "music games" which show an autonomous functioning. Language games have, however, an important function when we develop this comprehension in the light of the criteria of judgment that substantiate the manner in which music is incorporated in and operates within specific forms of life.

    Children with obesity experience stigma stemming from stereotypes, one such stereotype is that people with obesity are "sloppy" or have poor manners. Teaching children "proper table manners" has been proposed as an obesity prevention strategy. Little is known about the association between children's weight status and table manners. To examine correlates of child table manners and to examine the association of child table manners with child obese weight status and prospective change in child body mass index z-score (BMIz). Mother-child dyads (N = 228) participated in a videotaped laboratory eating task with cupcakes. Coding schemes to capture child table manners (making crumbs, chewing with mouth open, getting food on face, shoving food in mouth, slouching, and getting out of seat), and maternal attentiveness to child table manners, were reliably applied. Anthropometrics were measured at baseline and at follow-up two years later. Regression analyses examined the association of participant characteristics with child table manners, as well as the associations of child table manners with child obese weight status, and prospective change in BMIz/year. Predictors of poorer child table manners were younger child age, greater cupcake consumption, and greater maternal attentiveness to child table manners. Poorer child table manners were not associated with child obese (vs. not) weight status, but were associated with a prospective decrease in BMIz/year in children with overweight/obesity. Obesity interventions to improve table manners may be perpetuating unfavorable stereotypes and stigma. Future work investigating these associations is warranted to inform childhood obesity guidelines around table manners. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Lipids are produced, transported, and recognized by the concerted actions of numerous enzymes, binding proteins, and receptors. A comprehensive analysis of lipid molecules, "lipidomics," in the context of genomics and proteomics is crucial to understanding cellular physiology and pathology; consequently, lipid biology has become a major research target of the postgenomic revolution and systems biology. To facilitate international communication about lipids, a comprehensive classification of lipids with a common platform that is compatible with informatics requirements has been developed to deal with the massive amounts of data that will be generated by our lipid community. As an initial step in this development, we divide lipids into eight categories (fatty acyls, glycerolipids, glycerophospholipids, sphingolipids, sterol lipids, prenol lipids, saccharolipids, and polyketides) containing distinct classes and subclasses of molecules, devise a common manner of representing the chemical structures of individual lipids and their derivatives, and provide a 12 digit identifier for each unique lipid molecule. The lipid classification scheme is chemically based and driven by the distinct hydrophobic and hydrophilic elements that compose the lipid. This structured vocabulary will facilitate the systematization of lipid biology and enable the cataloging of lipids and their properties in a way that is compatible with other macromolecular databases.

    2016-05-01

    Full Text Available This paper aims at investigating the meaning of verb form ‘cook’ having one form with different manners of cooking something. Therefore, the analysis discusses about the various cooking manners in verb forms because cooking is an action or do something. The d ata was taken from the article about cooking procedure, by note taking technique. The data was further analyzed by natural semantics metalanguage. The result showed that verbs in cooking action have some similar meaning with different manners such as the manner cooking of blanch means cooking food into boiling water in a few minutes, while the manner cooking of steam means cooking food on the boiled water. Here, metalanguage manages to describe and analyze the verb meaning in cooking manners.

    There are specific relation properties of mother to the obese child. The mother representation in child is understand as a experience manner of herself. Representation (mental image) include perceptions, knowledge about characteristics and behaviors of a person and evaluation and experiences that provoke in others. The aim of this article is a trial of an answer what is a mental representation of mother experienced by obese girls and boys in adolescence. 21 obese persons (12 girls and 9 boys) and 23 persons of normal body mass (15 girls and 8 boys) have been investigated. The mean age of the investigated obese persons were 14.53, and for a person of normal body mass was 15.31. All persons were investigated by a clinical interview with 6 questions concerning mental mother representation. The obtained results were analyzed in relation to mental mother representation contents: cognitive, emotional, social, sexual, certificate, behavioral and somatic. Obese persons more often than the person of the normal body mass identify to mental mother representation somatic contents, more rarely social, sexual and behavioral contents. Obese girls more rarely than girls of the normal body mass identify to social contents, more often to somatic. Obese girls more rarely than obese boys identify to mental mother representation emotional contents, more often to somatic contents. The specific relation properties of mother to obese person in adolescence could be manifested in difficulties in turn on contents of mental mother representation, in external, somatic point of concern for mental mother representation, difficulties in contact with mental contents of mother representation.

    1993-01-01

    Previous investigations of the linguistic capacities of apes have focused on the ape's ability to produce words, and there has been little concern for comprehension. By contrast, it is increasingly recognized that comprehension precedes production in the language development of normal human children, and it may indeed guide production. It has been demonstrated that some species can process speech sounds categorically in a manner similar to that observed in humans. Consequently, it should be possible for such species to comprehend language if they have the cognitive capacity to understand word-referent relations and syntactic structure. Popular theories of human language acquisition suggest that the ability to process syntactic information is unique to humans and reflects a novel biological adaptation not seen in other animals. The current report addresses this issue through systematic experimental comparisons of the language comprehension skills of a 2-year-old child and an 8 year-old bonobo (Pan paniscus) who was raised in a language environment similar to that in which children are raised but specifically modified to be appropriate for an ape. Both subjects (child and bonobo) were exposed to spoken English and lexigrams from infancy, and neither was trained to comprehend speech. A common caretaker participated in the rearing of both subjects. All language acquisition was through observational learning. Without prior training, subjects were asked to respond to the same 660 novel sentences. All responses were videotaped and scored for accuracy of comprehension of the English language. The results indicated that both subjects comprehended novel requests and simple syntactic devices. The bonobo decoded the syntactic device of word recursion with higher accuracy than the child; however, the child tended to do better than the bonobo on the conjunctive, a structure that places a greater burden on short-term memory. Both subjects performed as well on sentences that

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available There is typological variation in the way languages encode manner as an element of a motion event. Languages like English view it as relevant, and the lexicalization of the variety of ways to move results in a rich class of motion verbs, contrary to other types of languages, like Romanian, which leave the manner element to be encoded by verbids or adverbs (for these reasons some linguists refer to the first type as manner-rich and second type as manner-poor languages. Still, several studies contrasting typologically different languages showed that languages of the latter type are not so poor in manner-of-motion verbs. The question then might rather be: which manner components are more likely to be lexicalized?For research purposes, we distinguish manner in terms of objective elements (medium, speed or intensity and subjective elements (attitude, intention. The aim of the study is to focus on the manner-of-motion verbs that embed an evaluative or qualitative dimension of motion and to examine the way these verbs encode somebody’s perspective in a narrative. The first question in such a case is whose evaluation or point of view is being represented. The second one is how the subjective point of view (narrative perspective mediated through manner-of-motion verbs in an English narrative (The Lord of the Rings, by J.R.R.

The aim of this paper is therefore to provide a framework for optimising comprehensibility in translation. In order to do so, the concept of intralingual translation is argued for as a useful starting point...

  16. Flaws in the Social Manners of Czech Managers

    Full Text Available We expect businesspeople, managers and representatives to know and apply Central European rules of etiquette. When travelling abroad or dealing with people from different countries the guest, of course, adjusts their behaviour according to their host, however, only as far as their own etiquette allows. However, many Czech managers are ignorant of the rules of their own etiquette. Nowadays, the knowledge of etiquette is becoming an economic must. It is evident that in order to gain or retain a job or be promoted one must abide by its rules. Companies no longer undue behaviour on the side of their employees or for such behaviour to harm the working atmosphere within the company. The more the professional qualification of employees evens out, the more their manners and neat appearance gain in importance. Significant deficiencies in this respect are apparent especially in dealing with foreigners. On international level, perfect manners are imperative.

    2012-01-01

    Lewd, crude, and rude behaviors of patients and staff members have the potential to complicate care; unfortunately, the medical literature on manners and etiquette is sparse. We sought to understand the impact of lewd, crude, and rude behaviors in the general hospital and to provide a context in which to educate clinicians about the management of troublesome behaviors of patients and staff members. We reviewed the history of etiquette in the general hospital, and discuss the ethical ramifications and clinical management of inappropriate behaviors. Lewd, crude, and rude language and behaviors are often heard and seen in the general hospital; such behaviors can be understood in a biopsychosocial context. Teaching trainees about manners and etiquette can help them identify and manage offensive behaviors and can facilitate the provision of effective and ethical care.

  2. Neuroimaging Evidence of Comprehension Monitoring

    Directory of Open Access Journals (Sweden)

    Linda Baker

    2014-04-01

    Full Text Available The purpose of this article is to synthesize the emerging neuroimaging literature that reveals how the brain responds when readers and listeners encounter texts that demand monitoring of their ongoing comprehension processes. Much of this research has been undertaken by cognitive scientists who do not frame their work in metacognitive terms, and therefore it is less likely to be familiar to psychologists who study metacognition in educational contexts. The important role of metacognition in the development and use of academic skills is widely recognized. Metacognition is typically defined as the awareness and control of one's own cognitive processes. In the domain of reading, the most important metacognitive skill is comprehension monitoring, the evaluation and regulation of comprehension. Readers who monitor their understanding realize when they have encountered difficulty making sense of the text, and they apply error correction procedures to attempt to resolve the difficulty. Metacognition depends on executive control skills that continue to develop into early adulthood, in parallel with the maturation of the executive control regions of the prefrontal cortex. Functional magnetic resonance imaging (fMRI and event-related potentials (ERP have been used for some time to study neural correlates of basic reading processes such as word identification, but it is only within recent years that researchers have turned to the higher-level processes of text comprehension. The article describes illustrative studies that reveal changes in neural activity when adults apply lexical, syntactic, or semantic standards to evaluate their understanding.

    2009-07-01

    The Apulian (South of Italy) territory saw the birth of a criminal organization called Sacra Corona Unita (SCU, United Holy Crown) which transformed the rules of traditional mafia organizations. This work examined 83 victims of the SCU between 1980 and 2000. The bodies were mainly of SCU members and in some cases, of police and law enforcement officers and other citizens caught in the crossfire. Some of these were discovered; thanks to the collaboration of "repented" SCU members who became police informers. The condition of the bodies varied in relation to the date and manner of killing. In some cases anthropometric research methods were necessary. In 73% of the cases, lesions of the head were the only marks left on the body. In conclusion, the existence of some social aspects connected with the symbolisms and membership rites that characterized the origin, evolution, and decline of the SCU is stressed.

    Identification of the mechanisms by which drugs of abuse cause neuronal dysfunction is essential for understanding the biological bases of their acute and long-lasting effects in the brain. Here, we performed real-time functional experiments of axonal transport of mitochondria to explore the role of in situ mitochondrial dysfunction in 3,4-methylenedioxymethamphetamine (MDMA; "ecstasy")-related brain actions. We showed that MDMA dramatically reduced mitochondrial trafficking in hippocampal neurons in a Tau-dependent manner, in which glycogen synthase kinase 3β activity was implicated. Furthermore, we found that these trafficking abnormalities were rescued by over-expression of Mitofusin2 and dynamin-related protein 1, but not of Miro1. Given the relevance of mitochondrial targeting for neuronal function and neurotransmission, our data underscore a novel mechanism of action of MDMA that may contribute to our understanding of how this drug of abuse alters neuronal functioning.

  6. Comprehensive Sediment Management to Improve Wetland Sustainability in Coastal Louisiana

    Khalil, S.; Freeman, A. M.; Raynie, R.

    2016-02-01

    Human intervention has impaired the Mississippi River's ability to deliver sediment to its deltaic wetlands, and as a consequence acute land loss in coastal Louisiana has resulted in an unprecedented ecocatastrophe. Since the 1930s, Louisiana has lost approximately 5,000 square kilometers of coastal land, and is continuing to lose land at the rate of approximately 43 square kilometers/year. This extreme rate of land loss threatens a range of key national assets and important communities. Coastal communities across the world as well as in Louisiana have realized the importance of sediment for the continuation of their very existence in these productive but vulnerable regions. Ecological restoration can only be undertaken on a stable coastline, for which sedimentological restoration is needed. A large-scale effort to restore coastal Louisiana is underway, guided by Louisiana's Comprehensive Master Plan for a Sustainable Coast. This 50-year, $50-billion plan prescribes 109 protection and restoration projects to reduce land loss, maintain and restore coastal environments and sustain communities. Nowhere else has a restoration and protection program of this scale been developed or implemented, and critical to its success is the optimized usage of limited fluvial and offshore sediment resources, and a keen understanding of the complex interactions of various geological/geophysical processes in ecosystem restoration. A comprehensive sediment management plan has been developed to identify and delineate potential sediment sources for restoration, and to provide a framework for managing sediment resources wisely, cost effectively, and in a systematic manner. The Louisiana Sediment Management Plan provides regional strategies for improved comprehensive management of Louisiana's limited sediment resources. Adaptive management via a robust system-wide monitoring plays an important role along with a regional approach for the efficient management of sediment resources.

  7. Understanding Climate Change and Sea Level: A Case Study of Middle School Student Comprehension and An Evaluation of Tide Gauges off the Panama Canal in the Pacific Ocean and Caribbean Sea

    Science.gov (United States)

    Millan-Otoya, Juan C.

    The present study had two main objectives. The first was to determine the degree of understanding of climate change, sea level and sea level rise among middle school students. Combining open-ended questions with likert-scaled questions, we identified student conceptions on these topics in 86 students from 7th and 8th grades during 2012 and 2013 before and after implementing a Curriculum Unit (CU). Additional information was obtained by adding drawings to the open-ended questions during the second year to gauge how student conceptions varied from a verbal and a visual perspective. Misconceptions were identified both pre- and post-CU among all the topics taught. Students commonly used climate and climate change as synonyms, sea level was often defined as water depth, and several students failed to understand the complexities that determine changes in sea level due to wind, tides, and changes in sea surface temperature. In general, 8th grade students demonstrated a better understanding of these topics, as reflected in fewer apparent misconceptions after the CU. No previous study had reported such improvement. This showed the value of implementing short lessons. Using Piaget's theories on cognitive development, the differences between 7th and 8th grade students reflect a transition to a more mature level which allowed students to comprehend more complex concepts that included multiple variables. The second objective was to determine if the frequency of sea level maxima not associated with tides over the last 100 years increased in two tide gauges located on the two extremes of the Panama canal, i.e. Balboa in the Pacific Ocean and Cristobal in the Caribbean Sea. These records were compared to time series of regional sea surface temperature, wind speed, atmospheric pressure, and El Nino-Southern Oscillation (ENSO), to determine if these played a role as physical drivers of sea level at either location. Neither record showed an increase in the frequency of sea level

  8. Oxytocin reverses osteoporosis in a sex dependent manner

    Full Text Available The increase of life expectancy has led to the increase of age-related diseases such as osteoporosis. Osteoporosis is characterized by bone weakening promoting the occurrence of fractures with defective bone regeneration. Men aged over 50 have a prevalence for osteoporosis of 20% which is related to a decline in sex hormones occurring during andropause or surgical orchidectomy. As we previously demonstrated in a mouse model for menopause in women that treatment with the neurohypophyseal peptide hormone oxytocin (OT normalizes body weight and prevents the development of osteoporosis, herein we addressed the effects of OT in male osteoporosis.Thus, we treated orchidectomized mice, an animal model suitable for the study of male osteoporosis, for 8 weeks with OT and then analyzed trabecular and cortical bone parameters as well as fat mass using micro-computed tomography. Orchidectomized mice displayed severe bone loss, muscle atrophy accompanied by fat mass gain as expected in andropause. Interestingly, OT treatment in male mice normalized fat mass as it did in female mice. However, although OT treatment led to a normalization of bone parameters in ovariectomized mice, this did not happen in orchidectomized mice. Moreover, loss of muscle mass was not reversed in orchidectomized mice upon OT treatment. All of these observations indicate that OT acts on fat physiology in both sexes, but in a sex specific manner with regard to bone physiology.

  9. Influence of manner of heating on functioning of fireplace

    1994-01-01

    In connection with a bioenergy research programme, there is an ongoing project for developing of wood-fired fireplaces. The overall target in the project is through research and development to improve the combustion and heating characteristics of fireplaces so that their harmful flue gas emissions are reduced and they become more appropriate sources of supplementary and reserve energy (e.g. when installed in electrically heated houses). In connection with this project, TTS Institute's Forestry Department conducted a study on the heating properties of a lightweight iron stove. Correct manner of heating is a means to reducing the amount of harmful flue gases produced by fireplaces and of raising their combustion efficiency. The content of environmentally harmful gases in the flue gases was at Its maximum when the stove was operated with little draught and with the combustion chamber full of fuel. By increasing the draught from 4 Pa to 32 Pa, the carbon monoxide content of the non-combusted gases was reduced almost by 75 percent. This was accompanied by nearly a doubling of the free heat loss of the flue gases. As well as being influenced by the draught in the flue, the functioning of the stove and completeness of combustion was influenced by the moisture content of the chopped firewood. A rise in the moisture level from 13 % to 40 % led to nearly a fivefold increase in the proportion of combustible gases in the flue gases

    The child's representation in the father is understood as an experience manner of itself. There are specific relation properties of the father to the obese child. The aim of this article is an attempt to explain/find out what is a mental representation of a child experienced by fathers of obese girls and boys. 30 fathers were investigated: 15 fathers of obese children (8 girls and 7 boys) and 15 fathers of children with normal body mass (8 girls and 7 boys). The mean age of the obese children of the investigated fathers was 8.23, and for normal body mass children of the investigated fathers it was 8.47. All fathers were investigated by a clinical interview with 15 questions concerning a mental child's representation. The obtained results were analyzed in relation to: 1. the contents of a mental father's representation of the child: cognitive, emotional, social, sexual, certificate, behavioral and somatic. 2. Access to a mental father's representation of the child. 3. Differentiation of a mental father's representation of the child. 4. Continuity of a mental father's representation of the child. 1. There are differences in a mental child's representation in fathers of obese and of normal body mass children. There are also differences in a mental child's representation in fathers of obese girls and boys 2. Fathers of obese children more often than the fathers of children with the normal body mass identify with the external contents of a mental child's representation. 1. A mental representation of an obese child in the father often contains external, not mental properties. 2. The representation of an obese child in the father contains deficit of mental properties. 3. Specific difficulties in the experience of a mental representation of an obese child in the father like f.e. emotional emptiness or dependence were pointed out.

  12. L-carnosine affects the growth of Saccharomyces cerevisiae in a metabolism-dependent manner.

    2012-01-01

    The dipeptide L-carnosine (β-alanyl-L-histidine) has been described as enigmatic: it inhibits growth of cancer cells but delays senescence in cultured human fibroblasts and extends the lifespan of male fruit flies. In an attempt to understand these observations, the effects of L-carnosine on the model eukaryote, Saccharomyces cerevisiae, were examined on account of its unique metabolic properties; S. cerevisiae can respire aerobically, but like some tumor cells, it can also exhibit a metabolism in which aerobic respiration is down regulated. L-Carnosine exhibited both inhibitory and stimulatory effects on yeast cells, dependent upon the carbon source in the growth medium. When yeast cells were not reliant on oxidative phosphorylation for energy generation (e.g. when grown on a fermentable carbon source such as 2% glucose), 10-30 mM L-carnosine slowed growth rates in a dose-dependent manner and increased cell death by up to 17%. In contrast, in media containing a non-fermentable carbon source in which yeast are dependent on aerobic respiration (e.g. 2% glycerol), L-carnosine did not provoke cell death. This latter observation was confirmed in the respiratory yeast, Pichia pastoris. Moreover, when deletion strains in the yeast nutrient-sensing pathway were treated with L-carnosine, the cells showed resistance to its inhibitory effects. These findings suggest that L-carnosine affects cells in a metabolism-dependent manner and provide a rationale for its effects on different cell types.

    Full Text Available The academic debate nowadays is focused on producing an applied science of learning, aiming to teach students how to learn and be strategic in their acquisition. The aim of the study is to identify and discuss the reading comprehension instruction approach applied in the Albanian system of education. Findings from 10 classes of Albanian language and literature with students of third grade were directly observed and analyzed, in order to gather evidence based on indicators and instruments that assess the way of reading comprehension. Findings were categorized according to strategy use; the frequency of their application in different classes was counted and represented in percentages. In this paper we will try to respond to questions like: What are students' main barriers of comprehending? Does the instructional approach respond to students’ needs and level of comprehension? Are teachers prepared to teach comprehension strategies? Furthermore, examples of procedures on how to deliver instruction of comprehension strategies in natural contexts will be represented. Results from teacher practices during lessons of reading comprehension confirmed that teachers use limited teaching strategies to deliver lessons. They mainly use strategies to test comprehension; while the approach of teaching students to read independently and strategically is an unknown practice.

  15. Interruptions disrupt reading comprehension.

    Foroughi, Cyrus K; Werner, Nicole E; Barragán, Daniela; Boehm-Davis, Deborah A

    2015-06-01

    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).

  16. Quotient-Comprehension Chains

    Directory of Open Access Journals (Sweden)

    Kenta Cho

    2015-11-01

    Full Text Available Quotients and comprehension are fundamental mathematical constructions that can be described via adjunctions in categorical logic. This paper reveals that quotients and comprehension are related to measurement, not only in quantum logic, but also in probabilistic and classical logic. This relation is presented by a long series of examples, some of them easy, and some also highly non-trivial (esp. for von Neumann algebras. We have not yet identified a unifying theory. Nevertheless, the paper contributes towards such a theory by introducing the new quotient-and-comprehension perspective on measurement instruments, and by describing the examples on which such a theory should be built.

    2017-01-01

    Plants possess large arsenals of immune receptors capable of recognizing all pathogen classes. To cause disease, pathogenic organisms must be able to overcome physical barriers, suppress or evade immune perception, and derive nutrients from host tissues. Consequently, to facilitate some of these processes, pathogens secrete effector proteins that promote colonization. This review covers recent advances in the field of effector biology, focusing on conserved cellular processes targeted by effectors from diverse pathogens. The ability of effectors to facilitate pathogen entry into the host interior, suppress plant immune perception, and alter host physiology for pathogen benefit is discussed. Pathogens also deploy effectors in a spatial and temporal manner, depending on infection stage. Recent advances have also enhanced our understanding of effectors acting in specific plant organs and tissues. Effectors are excellent cellular probes that facilitate insight into biological processes as well as key points of vulnerability in plant immune signaling networks. PMID:27359369

    2004-12-01

    In this experiment, we assessed the use of stereo visualizations as effective tools for topographic map learning. In most Earth Science courses, students spend extended time learning how to read topographic maps, relying on the lines of the map as indicators of height and accompanying distance. These maps often necessitate extended training for students to acquire an understanding of what they represent, how they are to be used, and the implementation of these maps to solve problems. In fact instructors often comment that students fail to adequately use such maps, instead relying on prior spatial knowledge or experiences which may be inappropriate for understanding topographic displays. We asked participants to study maps that provided 3-dimensional or 2-dimensional views, and then answer a battery of questions about features and processes associated with the maps. The results will be described with respect to the cognitive utility of visualizations as tools for map comprehension tasks.

    2014-06-01

    Previous reviews on participants' comprehension of informed consent information have focused on developed countries. Experience has shown that ethical standards developed on Western values may not be appropriate for African settings where research concepts are unfamiliar. We undertook this review to describe how informed consent comprehension is defined and measured in African research settings. We conducted a comprehensive search involving five electronic databases: Medline, Embase, Global Health, EthxWeb and Bioethics Literature Database (BELIT). We also examined African Index Medicus and Google Scholar for relevant publications on informed consent comprehension in clinical studies conducted in sub-Saharan Africa. 29 studies satisfied the inclusion criteria; meta-analysis was possible in 21 studies. We further conducted a direct comparison of participants' comprehension on domains of informed consent in all eligible studies. Comprehension of key concepts of informed consent varies considerably from country to country and depends on the nature and complexity of the study. Meta-analysis showed that 47% of a total of 1633 participants across four studies demonstrated comprehension about randomisation (95% CI 13.9-80.9%). Similarly, 48% of 3946 participants in six studies had understanding about placebo (95% CI 19.0-77.5%), while only 30% of 753 participants in five studies understood the concept of therapeutic misconception (95% CI 4.6-66.7%). Measurement tools for informed consent comprehension were developed with little or no validation. Assessment of comprehension was carried out at variable times after disclosure of study information. No uniform definition of informed consent comprehension exists to form the basis for development of an appropriate tool to measure comprehension in African participants. Comprehension of key concepts of informed consent is poor among study participants across Africa. There is a vital need to develop a uniform definition for

    We examined the implications of test differences for defining and diagnosing comprehension deficits using reading comprehension tests. We had 995 children complete the Gray Oral Reading Test-3, the Qualitative Reading Inventory-3, the Woodcock-Johnson Passage Comprehension-3, and the Peabody Individual Achievement Test, and compared which children were identified by each test as being in the lowest 10%. Although a child who performs so poorly might be expected to do poorly on all tests, we found that the average overlap between tests in diagnosing comprehension difficulties was only 43%. Consistency in diagnosis was greater for younger children, when comprehension deficits are due to weaker decoding skills, than for older children. Inconsistencies between tests were just as evident when identifying the top performers. The different children identified as having a comprehension deficit by each test were compared on four profile variables - word decoding skill, IQ, ADHD symptoms, and working memory skill – to understand the nature of the different deficits assessed by each test. Theoretical and practical implications of these test differences in defining and diagnosing comprehension deficits are discussed. PMID:22442251

  4. Neuropsychological deficits in temporal lobe epilepsy: A comprehensive review

    2014-01-01

    Full Text Available Temporal lobe epilepsy (TLE is the most prevalent form of complex partial seizures with temporal lobe origin of electrical abnormality. Studies have shown that recurrent seizures affect all aspects of cognitive functioning, including memory, language, praxis, executive functions, and social judgment, among several others. In this article, we will review these cognitive impairments along with their neuropathological correlates in a comprehensive manner. We will see that neuropsychological deficits are prevalent in TLE. Much of the effort has been laid on memory due to the notion that temporal lobe brain structures involved in TLE play a central role in consolidating information into memory. It seems that damage to the mesial structure of the temporal lobe, particularly the amygdale and hippocampus, has the main role in these memory difficulties and the neurobiological plausibility of the role of the temporal lobe in different aspects of memory. Here, we will cover the sub-domains of working memory and episodic memory deficits. This is we will further proceed to evaluate the evidences of executive function deficits in TLE and will see that set-shifting among other EFs is specifically affected in TLE as is social cognition. Finally, critical components of language related deficits are also found in the form of word-finding difficulties. To conclude, TLE affects several of cognitive function domains, but the etiopathogenesis of all these dysfunctions remain elusive. Further well-designed studies are needed for a better understanding of these disorders.

    The manufacturing of tablets involves many unit operations that possess multivariate and complex characteristics. The interactions between the material characteristics and process related variation are presently not comprehensively analyzed due to univariate detection methods. As a consequence......, current best practice to control a typical process is to not allow process-related factors to vary i.e. lock the production parameters. The problem related to the lack of sufficient process understanding is still there: the variation within process and material properties is an intrinsic feature...... and cannot be compensated for with constant process parameters. Instead, a more comprehensive approach based on the use of multivariate tools for investigating processes should be applied. In the pharmaceutical field these methods are referred to as Process Analytical Technology (PAT) tools that aim...

    OBJECTIVES: The costs of comprehensive cardiac rehabilitation are established and compared to the corresponding costs of usual care. The effect on health-related quality of life is analyzed. METHODS: An unprecedented and very detailed cost assessment was carried out, as no guidelines existed...... for the situation at hand. Due to challenging circumstances, the cost assessment turned out to be ex-post and top-down. RESULTS: Cost per treatment sequence is estimated to be approximately euro 976, whereas the incremental cost (compared with usual care) is approximately euro 682. The cost estimate is uncertain...... and may be as high as euro 1.877. CONCLUSIONS: Comprehensive cardiac rehabilitation is more costly than usual care, and the higher costs are not outweighed by a quality of life gain. Comprehensive cardiac rehabilitation is, therefore, not cost-effective....

  12. L-carnosine affects the growth of Saccharomyces cerevisiae in a metabolism-dependent manner.

    Directory of Open Access Journals (Sweden)

    Stephanie P Cartwright

    Full Text Available The dipeptide L-carnosine (β-alanyl-L-histidine has been described as enigmatic: it inhibits growth of cancer cells but delays senescence in cultured human fibroblasts and extends the lifespan of male fruit flies. In an attempt to understand these observations, the effects of L-carnosine on the model eukaryote, Saccharomyces cerevisiae, were examined on account of its unique metabolic properties; S. cerevisiae can respire aerobically, but like some tumor cells, it can also exhibit a metabolism in which aerobic respiration is down regulated. L-Carnosine exhibited both inhibitory and stimulatory effects on yeast cells, dependent upon the carbon source in the growth medium. When yeast cells were not reliant on oxidative phosphorylation for energy generation (e.g. when grown on a fermentable carbon source such as 2% glucose, 10-30 mM L-carnosine slowed growth rates in a dose-dependent manner and increased cell death by up to 17%. In contrast, in media containing a non-fermentable carbon source in which yeast are dependent on aerobic respiration (e.g. 2% glycerol, L-carnosine did not provoke cell death. This latter observation was confirmed in the respiratory yeast, Pichia pastoris. Moreover, when deletion strains in the yeast nutrient-sensing pathway were treated with L-carnosine, the cells showed resistance to its inhibitory effects. These findings suggest that L-carnosine affects cells in a metabolism-dependent manner and provide a rationale for its effects on different cell types.

  12. Nuclear size is sensitive to NTF2 protein levels in a manner dependent on Ran binding

    Science.gov (United States)

    Vuković, Lidija D.; Jevtić, Predrag; Zhang, Zhaojie; Stohr, Bradley A.; Levy, Daniel L.

    2016-01-01

    ABSTRACT Altered nuclear size is associated with many cancers, and determining whether cancer-associated changes in nuclear size contribute to carcinogenesis necessitates an understanding of mechanisms of nuclear size regulation. Although nuclear import rates generally positively correlate with nuclear size, NTF2 levels negatively affect nuclear size, despite the role of NTF2 (also known as NUTF2) in nuclear recycling of the import factor Ran. We show that binding of Ran to NTF2 is required for NTF2 to inhibit nuclear expansion and import of large cargo molecules in Xenopus laevis egg and embryo extracts, consistent with our observation that NTF2 reduces the diameter of the nuclear pore complex (NPC) in a Ran-binding-dependent manner. Furthermore, we demonstrate that ectopic NTF2 expression in Xenopus embryos and mammalian tissue culture cells alters nuclear size. Finally, we show that increases in nuclear size during melanoma progression correlate with reduced NTF2 expression, and increasing NTF2 levels in melanoma cells is sufficient to reduce nuclear size. These results show a conserved capacity for NTF2 to impact on nuclear size, and we propose that NTF2 might be a new cancer biomarker. PMID:26823604

    Coelho, Wagner Santos; Da Silva, Daniel; Marinho-Carvalho, Mônica Mesquita; Sola-Penna, Mauro

    2012-01-01

    Human and rat hepatic tissue express many serotonin (5-HT) receptor subtypes, such as 5-HT(1B), 5-HT(2A), 5-HT(2B) and 5-HT(7) receptors, which mediate diverse effects. 5-HT is known to regulate several key aspects of liver biology including hepatic blood flow, innervations and wound healing. 5-HT is also known to enhance net glucose uptake during glucose infusion in fasted dogs, but little is known about the ability of 5-HT to control hepatic glucose metabolism, especially glycolysis. This study addresses the potential of 5-HT to regulate PFK activity and the mechanisms related to the enzyme activity. Based on our results, we are the first to provide evidence that 5-HT up-regulates PFK in mouse hepatic tissue. Activation of the enzyme occurs through the 5-HT(2A) receptor and phospholipase C (PLC), resulting in PFK intracellular redistribution and favoring PFK association to the cytoskeletal f-actin-enriched fractions. Interestingly, 5-HT and insulin act in a synergistic manner, likely because of the ability of insulin to increase fructose-2,6-bisphosphate because the presence of this PFK allosteric regulator enhances the 5-HT effect on the enzyme activity. Together, these data demonstrate the ability of 5-HT to control hepatic glycolysis and present clues about the mechanisms involved in these processes, which may be important in understanding the action of 5-HT during the hepatic wound healing process.

  14. Stat3 signaling regulates embryonic stem cell fate in a dose-dependent manner

    Directory of Open Access Journals (Sweden)

    Chih-I Tai

    2014-09-01

    Full Text Available Stat3 is essential for mouse embryonic stem cell (mESC self-renewal mediated by LIF/gp130 receptor signaling. Current understanding of Stat3-mediated ESC self-renewal mechanisms is very limited, and has heretofore been dominated by the view that Stat3 signaling functions in a binary “on/off” manner. Here, in contrast to this binary viewpoint, we demonstrate a contextual, rheostat-like mechanism for Stat3's function in mESCs. Activation and expression levels determine whether Stat3 functions in a self-renewal or a differentiation role in mESCs. We also show that Stat3 induces rapid differentiation of mESCs toward the trophectoderm (TE lineage when its activation level exceeds certain thresholds. Stat3 induces this differentiation phenotype via induction of Tfap2c and its downstream target Cdx2. Our findings provide a novel concept in the realm of Stat3, self-renewal signaling, and pluripotent stem cell biology. Ultimately, this finding may facilitate the development of conditions for the establishment of authentic non-rodent ESCs.

  15. The effect of a sentence comprehension treatment on discourse comprehension in aphasia.

    2015-11-01

    While it is well understood that individuals with aphasia have difficulty with discourse comprehension, very few studies have examined the nature of discourse comprehension deficits in aphasia and the potential for improvement in discourse comprehension after rehabilitation. To address the first goal, we previously developed the Test of Syntactic Effects on Discourse Comprehension (TSEDC), which provides a measure of the extent to which a participant's sentence comprehension ability aids in comprehending passages (Levy et al., 2012). The goal of this study was to examine the effect of a sentence comprehension treatment on the TSEDC to assess if training participants to understand sentences of different syntactic complexity would improve their ability to understand passages that vary by their level of syntactic complexity. Forty participants with aphasia received sentence comprehension treatment using one of two syntactic comprehension tasks: object manipulation (OM) or sentence to picture matching (SPM). The dependent measure was improved sentence comprehension of one sentence type in one task-related protocol, with the order of task and structure counterbalanced across participants. Before and after treatment, participants also completed a self-paced auditory story comprehension task which involved 9 passages that contained either semantically reversible canonical sentences (simple passages) or semantically reversible noncanonical sentences (complex passages). At the end of each passage, participants were asked explicit or implicit questions about the story. Accuracy and reaction times were measured for each patient for each story before and after treatment. Analysis of the treatment data revealed that participants improved in their ability to understand trained sentences (both in terms of effect size and percent change on trained structure), irrespective of whether the trained task was SPM or OM. There was no significant relationship between treatment

    Directory of Open Access Journals (Sweden)

    Gang eWu

    2013-02-01

    Full Text Available Resilience is the ability to adapt successfully in the face of stress and adversity. Stressful life events, trauma and chronic adversity can have a substantial impact on brain function and structure, and can result in the development of PTSD, depression and other psychiatric disorders. However, most individuals do not develop such illnesses after experiencing stressful life events, and are thus thought to be resilient. Resilience as successful adaptation relies on effective responses to environmental challenges and ultimate resistance to the deleterious effects of stress, therefore a greater understanding of the factors that promote such effects is of great relevance. This review focuses on recent findings regarding genetic, epigenetic, developmental, psychosocial and neurochemical factors that are considered essential contributors to the development of resilience. Neural circuits and pathways involved in mediating resilience are also discussed. The growing understanding of resilience factors will hopefully lead to the development of new pharmacological and psychological interventions for enhancing resilience and mitigating the untoward consequences.

    Modern economists have built models of the labor market, which isolate the market’s key drivers and describe the way these interact to produce particular levels of unemployment. One of the most popular models used by macroeconomists today is the search-matching model of equilibrium unemployment. We explain this model, and show how it can be applied to understand the way various policies, such as unemployment benefits, taxes, or technological changes, can affect the unemployment rate.

Not necessarily of our own choice, but because tchnological development is moving so fast, that it will have still greater impact on many aspects of our lives. We have seen the beginnings of that change within the latest 35 years or so, but according to newest research that change will speed up immensely in the nearest years to come. The impact of that change or these changes will affect our working life immensely as a consequence of automation. How these changes are brought about and which are their consequences in a broad sense is being attempted to be understood and guessed by researchers. No one knows for sure, but specific patterns are visible. This paper will not try to guess, what will come, but will rather try to understand the deepest ”nature” of technology in order to understand the driving factors in this development: the genesis of technology in a broad sense in order to contibute to the understanding of the basis for the expected development.

Early literacy skills, including their relationship to one another, and the substantial impact of the setting and context, are critical in ensuring that children gain all of the preliminary skills and awareness they will need to become successful readers and writers. Research findings over the last few decades have led to a fuller understanding of all that emergent literacy includes, resulting in a need for a new, more comprehensive model. A new model, described in this article, strives to explain how emergent literacy can be viewed as an interactive process of skills and context rather than a linear series of individual components. Early literacy learning opportunities are more likely to happen when teachers have a solid knowledge base of emergent literacy and child development. Research has shown that preschool teachers with limited knowledge about literacy development are significantly less able to provide such experiences for children. Teachers will be better able to facilitate all of the components of emergent literacy if they have access to, and understanding of, a model that describes the components, their interactions, and the importance of environmental factors in supporting children.

  10. Justice foundations for the Comprehensive Law Movement.

    Dewhurst, Dale

    2010-01-01

    Authors examining the developing dispute resolution alternatives to the adversarial system have identified nine converging "vectors" or alternatives in what has been termed the Comprehensive Law Movement. These authors have sought to understand how the developing vectors can remain separate and vibrant movements while sharing common ground. Some analyze these developments as being within law and legal practice, others see them as alternative approaches to law, and still others take a combined approach. It will be impossible to understand how these vectors have meaningful differences from law and legal practice if the search is limited to looking within law and legal practice. It will be impossible to understand how these vectors have meaningful commonalities with law and legal practice if the search is limited to looking external to law and legal practice. Instead of comparing the vectors with the adversarial system, higher order criteria are required. What is needed is a comprehensive and internally consistent super-system of norms; one that can be used to evaluate the adversarial system and the evolving vectors on an equal footing. An Aristotelian natural law virtue theory of justice can: (a) provide a functional guiding definition of justice; (b) serve as a comprehensive and internally consistent super-system of norms; and (c) provide the theoretical and evaluative foundation required to clarify the relationships among the adversarial system and the developing vectors. Finally, it will become clear why the Comprehensive Law Movement might be more appropriately conceptualized as the Comprehensive Justice Movement. Copyright © 2010 Elsevier Ltd. All rights reserved.

  12. Strategy-based listening and pragmatic comprehension

    Directory of Open Access Journals (Sweden)

    Corsetti, Cristiane Ruzicki

    2014-01-01

    Full Text Available This article addresses the role of strategy-based listening as an alternative methodological approach to develop pragmatic comprehension in L2 contexts. Pragmatic comprehension refers to the understanding of speech acts and conversational implicatures. Listening comprehension comprises both bottom-up and top-down processes. Strategy-based listening encompasses the activation of pragmatic knowledge through pre-listening activities and the development of specific listening micro-skills. An empirical project which included a classroom project carried out with a group of eight learners preparing for the IELTS examination in 2009 corroborated the following assumptions: in order to achieve listening proficiency, learners need practice in making inferences as semantic and pragmatic inferences are embedded in verbal communication; semantic and pragmatic aspects affecting the meaning of utterances can be highlighted via comprehension activities focusing on specific listening subskills. The results of the classroom project suggested that strategy-based listening is potentially capable of directly enhancing pragmatic comprehension but were inconclusive with regards to pragmatic production

    Full Text Available This paper presents a study of the effects of texting on English language comprehension. The authors believe that English used in texting causes a lack of comprehension for English speakers, learners, and texters. Wei, Xian-hai and Jiang (2008:3 declare “In Netspeak, there are some newly-created vocabularies, which people cannot comprehend them either from their partial pronunciation or from their figures.” Crystal (2007:23 claims; “variation causes problems of comprehension and acceptability. If you speak or write differently from the way I do, we may fail to understand each other.”  In this paper, the authors conducted a questionnaire at Aligarh Muslim University to ninety respondents from five different Faculties and four different levels. To measure respondents’ comprehension of English texting, the authors gave the respondents abbreviations used by texters and asked them to write the full forms of the abbreviations. The authors found that many abbreviations were not understood, which suggested that most of the respondents did not understand and did not use these abbreviations.

    This lively introductory text exposes the student to the rewards of a rigorous study of functions of a real variable. In each chapter, informal discussions of questions that give analysis its inherent fascination are followed by precise, but not overly formal, developments of the techniques needed to make sense of them. By focusing on the unifying themes of approximation and the resolution of paradoxes that arise in the transition from the finite to the infinite, the text turns what could be a daunting cascade of definitions and theorems into a coherent and engaging progression of ideas. Acutely aware of the need for rigor, the student is much better prepared to understand what constitutes a proper mathematical proof and how to write one. Fifteen years of classroom experience with the first edition of Understanding Analysis have solidified and refined the central narrative of the second edition. Roughly 150 new exercises join a selection of the best exercises from the first edition, and three more project-sty...

    Ayurveda needs to achieve its full potential both in India and globally. This requires imparting to its students full appreciation of Ayurveda's power and strength, particularly proper understanding of the advantages of applying it to treat chronic and acute diseases. To this end, we explain the necessity of learning Sanskrit as a medium of study, and the advantages of learning the Texts in the traditional way, rather than relying on translations with all the loss of meaning and precision, which that entails. We emphasize the use of Triskandhakosha as a means to fully understand Ayurveda fundamental concepts and technical terms, so that all their shades of meaning are fully understood, and all their usages given in different places in the texts. Only by such methods can full appreciation of Ayurvedic wisdom be achieved, and the full depth and power of its knowledge be applied. Only then will its true status among systems of medicine come to be appreciated, either in India or more widely in the world as a whole.

    Prostatitis is a common urinary tract syndrome that many doctors find problematic to treat effectively. It is the third most commonly found urinary tract disease in men after prostate cancer and Benign Prostate Hyperplasia (BPH). Prostatitis may account for 25% of all office visits made to the urological clinics complaining about the genital and urinary systems all over the world. In the present study, we classified prostatitis and comprehensively elaborated the etiology, pathogenesis, diagnosis, and treatment of acute bacterial prostatitis (category I), chronic bacterial prostatitis (category II), chronic pelvic pain syndrome (CPPS) (category III), and asymptomatic prostatitis (category IV). In addition, we also tried to get some insights about other types of prostatitis-like fungal, viral and gonococcal prostatitis. The aim of this review is to present the detail current perspective of prostatitis in a single review. To the best of our knowledge currently, there is not a single comprehensive review, which can completely elaborate this important topic in an effective way. Furthermore, this review will provide a solid platform to conduct future studies on different aspects such as risk factors, mechanism of pathogenesis, proper diagnosis, and rational treatment plans for fungal, viral, and gonococcal prostatitis.

    2011-11-01

    Research has documented that few reported rapes are prosecuted by the legal system. The purpose of this study is to explain how the interactions between victims and detectives can strengthen or weaken the investigation itself. Twenty rape victims were interviewed to examine how law enforcement detectives' manner of questioning affects rape victims' level of disclosure. Using qualitative methodology, the results show that the detectives' manner of questioning can play a role in victims' disclosure. Detectives using a gentle manner of questioning with victims can help produce stronger victim statements and thus build stronger cases for prosecution.

    The Environmental Management Program at Los Alamos National Laboratory is in the process of initiating and then implementing a Comprehensive Environmental Management Plan (CEMP). There are several environmental impact and compliance drivers for this initiative. The Los Alamos CEMP is intended to be a flexible, long-range process that predicts, minimizes, treats, and disposes of any waste generated in execution of the Los Alamos mission - even if that mission changes. The CEMP is also intended to improve stakeholder and private sector involvement and access to environmental information. The total quality environmental management (TQEM) process will benchmark Los Alamos to private sector and DOE operations, identify opportunities for improvement, prioritize among opportunities, implement projects, measure progress, and spur continuous improvement in Environmental Management operations

    Full Text Available Psychodermatology is an interesting domain of dermatology that overlaps with psychiatry. This arena in dermatology has received limited diligence, partly due to lack of training in this realm. We present here a comprehensive review of salient features and treatment updates in primary psychiatric dermatoses and have also discussed the role of psyche in psychophysiological cutaneous disorders. Secondary psychiatric morbidity is relatively common among patients visiting the dermatologists but often overlooked and uncared for. Dermatologist should be able to initiate basic pharmacotherapy, should be knowledgeable about various non-pharmacological treatments and know the right time to refer the patient to the psychiatrist. Awareness and pertinent treatment of psychodermatological disorders among dermatologists will lead to a more holistic treatment approach and better prognosis in this unique group of patients.

  12. Maternal prenatal cortisol predicts infant negative emotionality in a sex-dependent manner.

    Prenatal stress influences fetal developmental trajectories, which may implicate glucocorticoid mechanisms. There is also emerging evidence that effects of prenatal stress on offspring development are sex-dependent. However, little is known about the prospective relationship between maternal prenatal cortisol levels and infant behaviour, and whether it may be different in male and female infants. We sought to address this question using data from a prospective longitudinal cohort, stratified by risk. The Wirral Child Health and Development Study (WCHADS) cohort (n=1233) included a stratified random sub-sample (n=216) who provided maternal saliva samples, assayed for cortisol, at home over two days at 32weeks of pregnancy (on waking, 30-min post-waking and during the evening) and a measure of infant negative emotionality from the Neonatal Behavioural Assessment Scale (NBAS) at five weeks-of-age. General population estimates of associations among measures were obtained using inverse probability weights. Maternal prenatal cortisol sampled on waking predicted infant negative emotionality in a sex-dependent manner (interaction term, p=0.005); female infants exposed to high levels of prenatal cortisol were more negative (Beta=0.440, p=0.042), whereas male infants were less negative (Beta=-0.407, p=0.045). There was no effect of the 30-min post-waking measure or evening cortisol. Our findings add to an emerging body of work that has highlighted sex differences in fetal programming, whereby females become more reactive following prenatal stress, and males less reactive. A more complete understanding of sex-specific developmental trajectories in the context of prenatal stress is essential for the development of targeted prevention strategies. Copyright © 2017.

    2010-09-01

    Full Text Available Ebolavirus (EBOV is an enveloped, single-stranded, negative-sense RNA virus that causes severe hemorrhagic fever with mortality rates of up to 90% in humans and nonhuman primates. Previous studies suggest roles for clathrin- or caveolae-mediated endocytosis in EBOV entry; however, ebolavirus virions are long, filamentous particles that are larger than the plasma membrane invaginations that characterize clathrin- or caveolae-mediated endocytosis. The mechanism of EBOV entry remains, therefore, poorly understood. To better understand Ebolavirus entry, we carried out internalization studies with fluorescently labeled, biologically contained Ebolavirus and Ebolavirus-like particles (Ebola VLPs, both of which resemble authentic Ebolavirus in their morphology. We examined the mechanism of Ebolavirus internalization by real-time analysis of these fluorescently labeled Ebolavirus particles and found that their internalization was independent of clathrin- or caveolae-mediated endocytosis, but that they co-localized with sorting nexin (SNX 5, a marker of macropinocytosis-specific endosomes (macropinosomes. Moreover, the internalization of Ebolavirus virions accelerated the uptake of a macropinocytosis-specific cargo, was associated with plasma membrane ruffling, and was dependent on cellular GTPases and kinases involved in macropinocytosis. A pseudotyped vesicular stomatitis virus possessing the Ebolavirus glycoprotein (GP also co-localized with SNX5 and its internalization and infectivity were affected by macropinocytosis inhibitors. Taken together, our data suggest that Ebolavirus is internalized into cells by stimulating macropinocytosis in a GP-dependent manner. These findings provide new insights into the lifecycle of Ebolavirus and may aid in the development of therapeutics for Ebolavirus infection.

    Full Text Available Understanding PISA Stephen DOWNESMoncton, CANADA ABSTRACT The headline was dramatic enough to cause a ripple in the reading public. "Students who use computers a lot at school have worse maths and reading performance," noted the BBC news article, citing a 2004 study by Ludger Woessmann and Thomas Fuchs (Fuchs and Woessman, 2004. It was not long before the blogosphere took notice. Taking the theme and running with it, Alice and Bill ask, "Computers Make School Kids Dumber?" They theorize, "If you track the admitted decline of education, you'll probably notice that it follows along with the increase of technology in the classroom." In a similar vein, James Bartholomew asks, "Do you think that the government will turn down the volume of its boasting about how it has spent billions introducing computers in schools (while keeping down the pay of teachers so much that there are shortages? Do you think it will stop sending governors of state schools glossy pamphlets about insisting that computers are used in their schools as much as possible?" In this study, therefore, PISA looks well beyond educational attainment, and also includes school demographics, such as whether it is a public or private school, has large or small classes, or has access or not to technological resources. Finally, it does measure student information-their family background, access to books and computers and parental support as well. The PISA survey departs from previous surveys in disregarding the stated curricula of the schools being measured. Therefore, the conclusion is not surprising, nor even wrong for him to consider independently of any parental or teacher support, considered without reference to the software running on it, considered without reference to student attitudes and interests, does not positively impact an education. Finally, he focus on missing the reporting of results

Hypnosis is a very "mental" or subjective phenomenon for both the client and the research participant. To better assess the mind of the client/participant during hypnosis, it is my belief that we need to generate more "precise" phenomenological descriptors of the mind during hypnosis and related empathic conditions, as Wickramasekera II (2015) has suggested in his article. Although any phenomenological methodology will have its limits and disadvantages, noetics (as defined in the article below) can help us better understand hypnosis, empathic involvement theory, and the brain/mind/behavior interface. By quantifying the mind in a comprehensive manner, just as the brain is comprehensively quantified via fMRI and qEEG technologies, noetic analysis can help us more precisely assess the mind and relate it to the brain and human behavior and experience.

    A mixed research design was used to examine how deaf students used the visual resources of a multimedia software package that was designed to support reading comprehension. The viewing behavior of 8 deaf students, ages 8-12 years, was recorded during their interaction with multimedia software that included narrative texts enriched with Greek Sign Language videos, pictures, and concept maps. Also, students' reading comprehension was assessed through reading comprehension questions and retelling. Analysis of the students' viewing behavior data, their answers to reading comprehension questions, their "think alouds," and their story retells indicated that they used visual resources, but they did not exploit them in a strategic manner to aid their reading comprehension. The study underscores the important role of mediated instruction in "visual literacy" skills that enable students to learn how to process visual aids in a way that supports their reading comprehension.

  5. The 2001 Comprehensive Review

    CERN Multimedia

    Åkesson, T

    A new approach for CERN to monitor the LHC-experiments' technical and scientific progress was introduced last year: The Comprehensive Reviews. A significant fraction of the full LHCC committee is mobilized during two days to review the complete project status. This event took place for ATLAS during 2-3 of July this year. With a rather exhaustive program we presented our status in 39 talks. It was a demanding and close to impossible task for the referees to comprehend the ATLAS status by listening to this massive amount of information, but from the ATLAS point-of-view we judged it important that the referees were exposed to both the progress and the remaining problem areas. The referees were satisfied with our status; probably more so this year than last year. They judged the main critical issues to be: The schedules of the barrel toroid, the end-cap TRT, the LAr barrel and end-cap A, and the MDTs. The procurement of radiation hard electronics was also thought to be a critical issue. They were informed of ...

    The Ernest Orlando Lawrence Berkeley National Laboratory`s Comprehensive Facilities Plan (CFP) document provides analysis and policy guidance for the effective use and orderly future development of land and capital assets at the Berkeley Lab site. The CFP directly supports Berkeley Lab`s role as a multiprogram national laboratory operated by the University of California (UC) for the Department of Energy (DOE). The CFP is revised annually on Berkeley Lab`s Facilities Planning Website. Major revisions are consistent with DOE policy and review guidance. Facilities planing is motivated by the need to develop facilities for DOE programmatic needs; to maintain, replace and rehabilitate existing obsolete facilities; to identify sites for anticipated programmatic growth; and to establish a planning framework in recognition of site amenities and the surrounding community. The CFP presents a concise expression of the policy for the future physical development of the Laboratory, based upon anticipated operational needs of research programs and the environmental setting. It is a product of the ongoing planning processes and is a dynamic information source.

    Although it has been a stated policy goal of American and Soviet leaders since 1958 (with the exception of Ronald Reagan), the world today is still without a Comprehensive Test Ban Treaty. Throughout their history, test an negotiatins have been plagued by a number of persistent problems. Chief among these is East-West differences on the verification question, with the United States concerned about the problem of possible Soviet cheating and the USSR concerned about the protection of its national sovereignty. In addition, internal bureaucratic politics have played a major role in preventing the successful conclusion of an agreement. Despite these problems, the superpowers have concluded several significant partial meausres: a brief (1958-1961) total moratorium on nuclear weapons tests; the Limited Test Ban Treaty of 1963, banning tests in the air, water and outer space; the Threshold Test Ban Treaty of 1974 (150 KT limit on underground explosions); and the Peaceful Nuclear Explosions Treaty of 1976 (150 KT limit on individal PNEs). Today, the main U.S. objections to a CTBT center is the nuclear weapons laboratories, the Department of Energy, and the Pentagon, who all stress the issues of stockpile reliability and verification. Those who remain committed to a CTBT emphasize and the potential political leverage it offers in checking both horizontal and vertical proliferation.

  9. Rereading Comprehension Pedagogies: Toward a Dialogic Teaching Ethic that Honors Student Sensemaking

    Directory of Open Access Journals (Sweden)

    Maren Aukerman

    2013-06-01

    Full Text Available This conceptual essay critiques reading comprehension pedagogies that are part of the current educational landscape.  I argue that comprehension pedagogy generally reflects one of three differing orientations, each with its own assumptions about what comprehension is:  comprehension-as-outcome pedagogies, which emphasize getting textual meaning “right”; comprehension-as-procedure pedagogies, which emphasize knowing the “right” ways doing reading; and comprehension-as-sensemaking pedagogies, which take all textual interpretation seriously, regardless of “rightness.”  Comprehension-as-sensemaking pedagogies, in turn, can be distinguished as either primarily responsive – aimed at surfacing student understandings – or primarily dialogic – aimed at getting student understandings to refract.  Arguably, comprehension-as-outcome pedagogy dominates current reading instruction.  A focus on measuring and teaching toward “right” interpretations permeates almost all aspects of comprehension pedagogy even when one of the other orientations toward comprehension pedagogy is also at play.  While seemingly intuitive, this overarching outcome emphasis reifies textual meaning in ways that are both theoretically and ethically problematic.  I make the case that comprehension-as-sensemaking pedagogy should become primary instead.  I propose that comprehension-as-outcome and comprehension-as-procedure pedagogies should not be abandoned, but should be subordinated to dialogic comprehension-as-sensemaking pedagogy so that students’ textual sensemaking is more fully heard, respected, and examined in reading classrooms.

    operator. The reports' readability and comprehensibility for patients have only scarcely been considered in the current legal resolutions, and there is no undergoing process of improvement. The analysis has shown that there is in fact an urgent need for action. Future reports should therefore ensure that their textual content is formulated in a readable and comprehensible recipient-friendly manner. To enhance customer-oriented transparency within the German public health service patients should be able to fully understand what hospitals want to communicate. Therefore the further process of research will focus on the development of specific criteria for the production of textual reports. This has to be done in co-operation with patients and resident general practitioners.

    This study has the objective of understanding the training of nurses for comprehensive health care. It used data from interviews with teachers, students and service nurses submitted to discourse analysis. There is an understanding of comprehensive care in the training of nurses from the perspective of establishing a healthcare model in which care is directed to the patient. There are reflections regarding the technologies and the form of organization of the work, expressed in a permanent tension: Clinical versus Collective Health as a challenge for comprehensive care. It was identified that building completeness in the formation implies assuming acting in health as an educative principle in a new form of learning-teaching in health, which breaks up with pre-formed, out-of-context knowledge. The conclusion is that comprehensive health care is taken as an object of reflection in the movement for change in the pedagogical practices, and that it is reflected in health attention.

    Paul van den Brook

    2011-07-01

    Full Text Available To understand what they read or hear, children and adults must create a coherent mental representation of presented information. Recent research suggests that the ability to do so starts to develop early –well before reading age- and that early individual differences are predictive of later reading-comprehension performance. In this paper, we review this research and discuss potential applications to early intervention. We then present two exploratory studies in which we examine whether it is feasible to design interventions with early readers (3rd grade and even toddlers (2-3 years old. The interventions employed causal questioning techniques as children listen to orally presented, age-appropriate narratives. Afterwards, comprehension was tested through question answering and recall tasks. Results indicate that such interventions are indeed feasible. Moreover, they suggest that for both toddlers and early readers questions during comprehension are more effective than questions after comprehension. Finally, for both groups higher working memory capacity was related to better comprehension.

    2014-05-01

    Although individuals with Parkinson's disease (PD) self-report reading problems and experience difficulties in cognitive-linguistic functions that support discourse-level reading, prior research has primarily focused on sentence-level processing and auditory comprehension. Accordingly, the authors investigated the presence and nature of reading comprehension in PD, hypothesizing that (a) individuals with PD would display impaired accuracy and/or speed on reading comprehension tests and (b) reading performances would be correlated with cognitive test results. Eleven adults with PD and 9 age- and education-matched control participants completed tests that evaluated reading comprehension; general language and cognitive abilities; and aspects of attention, memory, and executive functioning. The PD group obtained significantly lower scores on several, but not all, reading comprehension, language, and cognitive measures. Memory, language, and disease severity were significantly correlated with reading comprehension for the PD group. Individuals in the early stages of PD without dementia or broad cognitive deficits can display reading comprehension difficulties, particularly for high- versus basic-level reading tasks. These reading difficulties are most closely related to memory, high-level language, and PD symptom severity status. The findings warrant additional research to delineate further the types and nature of reading comprehension impairments experienced by individuals with PD.

    2013-12-01

    Many studies have examined the characteristics of gunshot wounds by manner of death; however, no published study has directly compared these characteristics for the different types of firearms. This study was designed to address that deficiency. Existing data sets of nonaccidental deaths by handguns, shotguns, and rifles were reviewed. The victim data were analyzed by age and sex of the victims, wound location, range of fire, manner of death, and type of firearm. Handguns were the most common firearm used in both suicides and homicides, followed by rifles and then shotguns. For both homicides and suicides, there were significant differences between the firearm types for age of victims, range of fire, and wound locations. Possible reasons for those differences are discussed. It is concluded that information about the type of firearm is crucial to have when examining the nature of a firearm injury and determining the manner of death.

  2. A research on comprehension differences between print and screen reading

    Full Text Available Since the 1980s, extensive research has been conducted comparing reading comprehension from printed text and computer screens. The conclusions, however, are not very consistent. As reading from computer screens requires a certain degree of individual technical skill, such variables should be objectively taken into consideration when conducting an experiment regarding the comparison between print and screen reading. This study analyses the difference in the level of understanding of the two presentational formats (text on printed pages and hypertext on computer screens for people between 45-54 years of age (i.e. “middleaged” adults. In our experimental findings there were no significant differences between the levels of comprehension for print and screen presentations. With regard to individual differences in gender, age group and educational level, the findings are as follows: gender and education effects on print reading comprehension performance were significant, while those on screen reading comprehension performance were not. For middle-aged computer learners, the main effect of age group on both print and screen reading comprehension performance was insignificant. In contrast, linear texts of traditional paper-based material are better for middle-aged readers’ literal text comprehension, while hypertext is beneficial to their inferential text comprehension. It is also suggested that hypermedia could be used as a cognitive tool for improving middle-aged adults’ inferential abilities on reading comprehension, provided that they were trained adequately to use available computers.

  3. Flexibility in embodied language understanding

    Directory of Open Access Journals (Sweden)

    2011-06-01

    Full Text Available Do people use sensori-motor cortices to understand language? Here we review neurocognitive studies of language comprehension in healthy adults and evaluate their possible contributions to theories of language in the brain. We start by sketching the minimal predictions that an embodied theory of language understanding makes for empirical research, and then survey studies that have been offered as evidence for embodied semantic representations. We explore four debated issues: first, does activation of sensori-motor cortices during action language understanding imply that action semantics relies on mirror neurons? Second, what is the evidence that activity in sensori-motor cortices plays a functional role in understanding language? Third, to what extent do responses in perceptual and motor areas depend on the linguistic and extra-linguistic context? And finally, can embodied theories accommodate language about abstract concepts? Based on the available evidence, we conclude that sensori-motor cortices are activated during a variety of language comprehension tasks, for both concrete and abstract language. Yet, this activity depends on the context in which perception and action words are encountered. Although modality-specific cortical activity is not a sine qua non of language processing even for language about perception and action, sensori-motor regions of the brain appear to make functional contributions to the construction of meaning, and should therefore be incorporated into models of the neurocognitive architecture of language.

    The primary goal of psycholinguistic research is to understand the architectures and mechanisms that underlie human language comprehension and production. This entails an understanding of how linguistic knowledge is represented and organized in the brain and a theory of how that knowledge is accessed when we use language. Research has traditionally emphasized purely linguistic aspects of on-line comprehension, such as the influence of lexical, syntactic, semantic and discourse constraints, and their tim -course. It has become increasingly clear, however, that nonlinguistic information, such as the visual environment, are also actively exploited by situated language comprehenders.

    Death resulting from burns is an important social problem and a frequent accident. However, because approximately 10% of cases are estimated to result from a fire that was deliberately started, all fire-related deaths should be treated as suspicious, and the cause of a fire should be investigated. For the bodies recovered from the scene of a fire, the manner of death could also be suicide or homicide. The objective of this study was to contribute to the clarification of controversial data present in the literature on the manner of death determination of fire-related deaths, through evaluation of autopsy findings of bodies recovered from fires. We reviewed 20,135 autopsies performed in a 5-year period, in Istanbul, as the whole autopsy data of the city and found 133 fire-related deaths. The death scene investigation reports and other judicial documents, autopsy findings, and toxicological analysis results were evaluated to determine the parameters of age, sex, level of the burn, vital signs [red flare; soot in the lower respiratory tract, esophagus, and/or stomach; and screening of carboxyhemoglobin (COHb) levels in the blood], toxicological substances, presence of accelerants, cause of death, and manner of death. The manner of death was determined to be an accident in 98 (73.7%) and homicide in 12 (9%) cases, whereas there was no suicide. In addition, it could not be determined in 23 (17.2%) cases. In accidental deaths, the most frequent cause of death was COHb poisoning with statistically significant blood COHb levels greater than 10%. Further, the presence of soot in the lower respiratory tract, esophagus, and/or stomach and the existence of at least 1 or 2 vital signs together were found to be valid deterministic criteria with statistical significance in terms of identifying the manner of death.

    1999-06-01

    Many classrooms are noisy and this interferes with listening and teaching. FM soundfield (FM) amplification systems have been developed which provide a uniform soundfield throughout the classroom and increase the speech-signal:noise ratio. The effect on comprehension of such a system was investigated. Forty-nine pupils (comprising the two top classes of a mainstream primary school) participated in this study, with a mean age of 9.92 years (range 8.58-11.42 years). The Neale Analysis of Reading Ability (Neale, 1988a, b) was modified and administered as a spoken comprehension test. Tests of nonverbal intelligence, auditory memory and a questionnaire were given. The passages spoken though the FM amplification system were understood better than the comparable unamplified passages. Auditory memory, sex and non-verbal intelligence had no effect on improved comprehension. FM amplification significantly improved comprehension and could be considered for use in other schools.

  16. Language comprehension warps the mirror neuron system

    Directory of Open Access Journals (Sweden)

    Noah eZarr

    2013-12-01

    Full Text Available Is the mirror neuron system (MNS used in language understanding? According to embodied accounts of language comprehension, understanding sentences describing actions makes use of neural mechanisms of action control, including the MNS. Consequently, repeatedly comprehending sentences describing similar actions should induce adaptation of the MNS thereby warping its use in other cognitive processes such as action recognition and prediction. To test this prediction, participants read blocks of multiple sentences where each sentence in the block described transfer of objects in a direction away or toward the reader. Following each block, adaptation was measured by having participants predict the end-point of videotaped actions. The adapting sentences disrupted prediction of actions in the same direction, but a only for videos of biological motion, and b only when the effector implied by the language (e.g., the hand matched the videos. These findings are signatures of the mirror neuron system.

    Predictive testing for Huntington disease is a complex decision, requiring in-depth counseling, education, and evaluation. Despite the growth in Web-based decision aids and educational resources, such tools for those considering Huntington disease testing are not available. The main objective of this project was to develop a patient-friendly, comprehensive, accessible Web-based tool to provide accurate information about testing for Huntington disease. A semistructured interview study was conducted to determine the informational, educational, and support needs of those considering Huntington disease testing. A dedicated predictive testing website was subsequently developed and pilot tested. The interview study revealed that an effective website should include interactive diagrams, video documentaries, and personal stories of others who had considered testing. The pilot test revealed that the multidimensional site was easy to navigate and understand and provided an accurate, unbiased overview of the important factors to be considered before undergoing predictive testing. This project demonstrates the use of a mixed-method approach to develop the first tailored website dedicated to predictive testing for Huntington disease. Such an approach enabled the development of a comprehensive, accurate, and effective educational tool that supports informed decision making for people considering predictive testing for Huntington disease in an accessible, nonthreatening manner.

    During the last century, dental research has focused on unraveling the mechanisms behind various oral pathologies, while oral health was typically described as the mere absence of oral diseases. The term 'oral microbial homeostasis' is used to describe the capacity of the oral ecosystem to maintain microbial community stability in health. However, the oral ecosystem itself is not stable: throughout life an individual undergoes multiple physiological changes while progressing through infancy, childhood, adolescence, adulthood and old age. Recent discussions on the definition of general health have led to the proposal that health is the ability of the individual to adapt to physiological changes, a condition known as allostasis. In this paper the allostasis principle is applied to the oral ecosystem. The multidimensionality of the host factors contributing to allostasis in the oral cavity is illustrated with an example on changes occurring in puberty. The complex phenomenon of oral health and the processes that prevent the ecosystem from collapsing during allostatic changes in the entire body are far from being understood. As yet individual components (e.g. hard tissues, microbiome, saliva, host response) have been investigated, while only by consolidating these and assessing their multidimensional interactions should we be able to obtain a comprehensive understanding of the ecosystem, which in turn could serve to develop rational schemes to maintain health. Adapting such a 'system approach' comes with major practical challenges for the entire research field and will require vast resources and large-scale multidisciplinary collaborations. 2015 S.

    Full Text Available To understand what they read or hear, children and adults must create a coherent mental representation of presented information. Recent research suggests that the ability to do so starts to develop early –well before reading age- and that early individual differences are predictive of later reading-comprehension performance. In this paper, we review this research and discuss potential applications to early intervention. We then present two exploratory studies in which we examine whether it is feasible to design interventions with early readers (3rd grade and even toddlers (2-3 years old. The interventions employed causal questioning techniques as children listen to orally presented,age-appropriate narratives. Afterwards, comprehension was tested through question answering and recall tasks. Results indicate that such interventions are indeed feasible. Moreover, they suggest thatfor both toddlers and early readers questions during comprehension are more effective than questions after comprehension. Finally, for both groups higher working memory capacity was related to bettercomprehension.

    Many anticancer therapeutic agents cause bone loss, which increases the risk of fractures that severely reduce quality of life. Thus, in drug development, it is critical to identify and understand such effects. Anticancer therapeutic and HSP90 inhibitor 17-(allylamino)-17-demethoxygeldanamycin (17-AAG) causes bone loss by increasing osteoclast formation, but the mechanism underlying this is not understood. 17-AAG activates heat shock factor 1 (Hsf1), the master transcriptional regulator of heat shock/cell stress responses, which may be involved in this negative action of 17-AAG upon bone. Using mouse bone marrow and RAW264.7 osteoclast differentiation models we found that HSP90 inhibitors that induced a heat shock response also enhanced osteoclast formation, whereas HSP90 inhibitors that did not (including coumermycin A1 and novobiocin) did not affect osteoclast formation. Pharmacological inhibition or shRNAmir knockdown of Hsf1 in RAW264.7 cells as well as the use of Hsf1 null mouse bone marrow cells demonstrated that 17-AAG-enhanced osteoclast formation was Hsf1-dependent. Moreover, ectopic overexpression of Hsf1 enhanced 17-AAG effects upon osteoclast formation. Consistent with these findings, protein levels of the essential osteoclast transcription factor microphthalmia-associated transcription factor were increased by 17-AAG in an Hsf1-dependent manner. In addition to HSP90 inhibitors, we also identified that other agents that induced cellular stress, such as ethanol, doxorubicin, and methotrexate, also directly increased osteoclast formation, potentially in an Hsf1-dependent manner. These results, therefore, indicate that cellular stress can enhance osteoclast differentiation via Hsf1-dependent mechanisms and may significantly contribute to pathological and therapeutic related bone loss.

  1. Mathematical analysis demonstrates that interferons-β and -γ Interact in a multiplicative manner to disrupt herpes simplex virus replication

    Several studies suggest that the innate interferons (IFNs), IFN-α and IFN-β, can act in concert with IFN-γto synergistically inhibit the replication of cytomegalovirus and herpes simplex virus type 1 (HSV-1). The significance of this observation is not yet agreed upon in large part because the nature and magnitude of the interaction between IFN-α/β and IFN-γ is not well defined. In the current study, we resolve this issue by demonstrating three points. First, the hyperbolic tangent function, tanh (x  ), can be used to describe the individual effects of IFN-β or IFN-γ on HSV-1 replication over a 320,000-fold range of IFN concentration. Second, pharmacological methods prove that IFN-β and IFN-γ interact in a greater-than-additive manner to inhibit HSV-1 replication. Finally, the potency with which combinations of IFN-β and IFN-γ inhibit HSV-1 replication is accurately predicted by multiplying the individual inhibitory effects of each cytokine. Thus, IFN-β and IFN-γ interact in a multiplicative manner. We infer that a primary antiviral function of IFN-γ lies in its capacity to multiply the potency with which IFN-α/β restricts HSV-1 replication in vivo. This hypothesis has important ramifications for understanding how T lymphocyte-secreted cytokines such as IFN-γ can force herpesviruses into a latent state without destroying the neurons or leukocytes that continue to harbor these viral infections for the lifetime of the host.

    Full Text Available The authors review five major findings in reading comprehension and their implications for educational practice. First, research suggests that comprehension skills are separable from decodingprocesses and important at early ages, suggesting that comprehension skills should be targeted early, even before the child learns to read. Second, there is an important distinction between readingprocesses and products, as well as their causal relationship: processes lead to certain products. Hence, instructional approaches and strategies focusing on processes are needed to improve students’reading performance (i.e., product. Third, inferences are a crucial component of skilled comprehension. Hence, children need scaffolding and remediation to learn to generate inferences, even when they know little about the text topic. Fourth, comprehension depends on a complex interaction between the reader, the characteristics of the text, and the instructional task, highlighting the need for careful selection of instructional materials for individual students and specific groups of students. Finally, educators may benefit from heightened awareness of the limitations and inadequacies of standardized reading comprehension assessments, as well as the multidimensionality of comprehension to better understand their students’ particular strengths and weaknesses.

    2015-01-01

    The present study investigated the conditions under which multitasking impairs reading comprehension. Participants read prose passages (the primary task), some of which required them to perform a secondary task. In Experiment 1, we compared two different types of secondary tasks (answering trivia questions and solving math problems). Reading comprehension was assessed using a multiple-choice test that measured both factual and conceptual knowledge. The results showed no observable detrimental effects associated with multitasking. In Experiment 2, the secondary task was a cognitive load task that required participants to remember a string of numbers while reading the passages. Performance on the reading comprehension test was lower in the cognitive load conditions relative to the no-load condition. The present study delineates the conditions under which multitasking can impair or have no effect on reading comprehension. These results further our understanding of our capacity to multitask and have practical implications in our technologically advanced society in which multitasking has become commonplace.

    Athletic Pubalgia, more commonly known as sports hernia, is defined as chronic lower abdominal and groin pain without the presence of a true hernia. It is increasingly recognized in athletes as a source of groin pain and is often associated with other pathology. A comprehensive approach to the physical exam and a strong understanding of hip and pelvic anatomy are critical in making the appropriate diagnosis. Various management options are available. We review the basic anatomy, patholophysiology, diagnostic approach and treatment of athletic pubalgia as well as discuss associated conditions such as femoroacetabular impingement.

    Full Text Available Daniel Gologorsky1, Scott H Greenstein2 1Dartmouth Medical School, Hanover, NH, USA; 2Department of Ophthalmology, Massachusetts Eye and Ear Infirmary, Harvard Medical School, Boston, MA, USA Abstract: Patients choose to seek a second opinion in matters related to their health for a variety of reasons, and the total cost associated with these second opinion visits is estimated to be billions of dollars annually. Understanding the reasons behind second opinion self-referrals is key to improving patient satisfaction and reducing redundancy in delivered health care. This study represents a retrospective analysis of the records from a single provider at the Massachusetts Eye and Ear Infirmary (MEEI Comprehensive Ophthalmology Service in order to determine the various reasons that patients self-refer to an ophthalmology clinic seeking second opinions. A total of 174 patients presenting for a second opinion were identified over a one-year period. Patients presented for second opinions for two primary reasons: 60% presented in order to seek a confirmation of a diagnosis from an outside ophthalmologist (54% or optometrist (6%, and 40% presented due to a previous adverse experience with an outside provider, such as perceived treatment failure (26%, poor bedside manner (3%, distrust of the provider (5%, and poor provider communication skills (7%. This study strives to reiterate that the reduction of adverse patient experiences through effective communication of expected treatment options and outcomes, with a realistic time course of therapy, could significantly improve patient satisfaction and reduce costly second opinion visits.

  8. Memory mechanisms supporting syntactic comprehension.

    2013-04-01

    Efforts to characterize the memory system that supports sentence comprehension have historically drawn extensively on short-term memory as a source of mechanisms that might apply to sentences. The focus of these efforts has changed significantly in the past decade. As a result of changes in models of short-term working memory (ST-WM) and developments in models of sentence comprehension, the effort to relate entire components of an ST-WM system, such as those in the model developed by Baddeley (Nature Reviews Neuroscience 4: 829-839, 2003) to sentence comprehension has largely been replaced by an effort to relate more specific mechanisms found in modern models of ST-WM to memory processes that support one aspect of sentence comprehension--the assignment of syntactic structure (parsing) and its use in determining sentence meaning (interpretation) during sentence comprehension. In this article, we present the historical background to recent studies of the memory mechanisms that support parsing and interpretation and review recent research into this relation. We argue that the results of this research do not converge on a set of mechanisms derived from ST-WM that apply to parsing and interpretation. We argue that the memory mechanisms supporting parsing and interpretation have features that characterize another memory system that has been postulated to account for skilled performance-long-term working memory. We propose a model of the relation of different aspects of parsing and interpretation to ST-WM and long-term working memory.

    2011-11-01

    This study investigated the relationship between emotion comprehension, grammar comprehension, and working memory capacity in children between 5 and 11 years (n= 130), testing the hypothesis that working memory has a role in the development of emotion comprehension. We replicated the correlation between emotion comprehension and grammar comprehension, and found that working memory capacity correlates with both of these variables (also with age statistically controlled). The significant effect of age on emotion comprehension was eliminated when working memory capacity was co-varied. In a regression analysis of emotion comprehension scores, when working memory capacity was entered as a predictor, no additional variance was significantly accounted for by grammar comprehension, gender, or age. A structural relations model, in which the paths from working memory capacity to emotion comprehension and from working memory capacity to grammar comprehension account fully for the correlation between grammar and emotion comprehension, fit the data well. However, working memory capacity was not equally related to all components of the Test of Emotion Comprehension (TEC) (Pons & Harris, 2000), the relationship being significant only for some of them. In particular, working memory capacity has a decisive role in the transition from understanding external to mental aspects of emotions. It is concluded that the development of working memory has a considerable impact on the development of emotion comprehension. ©2010 The British Psychological Society.

    2016-11-01

    This study probes how individual differences in early event perception predict later verb knowledge. At Time 1, when infants were 13 to 15months of age, they saw videotaped silent scenes performed by a human actor. The goal was to see whether infants could form categories of path (a figure's trajectory with respect to a ground object) and manner (how an action is performed). Infants either saw the same manner (e.g., jogging) taking place across three different paths (around, through, and behind) or saw the same path (e.g., around a tent) taking place across three different manners (running, crawling, and walking). After familiarization, either the path or the manner was changed and visual fixation was monitored using preferential looking. At Time 2, the same children were tested on their comprehension of verbs in a two-choice pointing task showing two simultaneous actions (e.g., running vs. jumping). Success at categorization of path and manner at Time 1 predicted verb comprehension at Time 2, even when taking language knowledge at both time points into account. These preliminary results represent headway in identifying the factors that may contribute to children's language learning. They suggest that skill in categorizing semantic components present in nonlinguistic events is predictive of children's later verb vocabulary. Copyright © 2016 Elsevier Inc. All rights reserved.

    This experiment examined the time course of integration of modifier-noun (conceptual) combinations during auditory sentence comprehension using cross-modal lexical priming. The study revealed that during ongoing comprehension, there is initial activation of features of the noun prior to activation of (emergent) features of the entire conceptual combination. These results support compositionality in conceptual combination; that is, they indicate that features of the individual words constituting a conceptual combination are activated prior to combination of the words into a new concept.

    2015-01-01

    Supplying peak energy demand in a cost effective, reliable manner is a critical focus for utilities internationally. Successfully addressing peak energy concerns requires understanding of all the factors that affect electricity demand especially at peak times. This paper is based on past attempts of proposing models designed to aid our understanding of the influences on residential peak energy demand in a systematic and comprehensive way. Our model has been developed through a group model building process as a systems framework of the problem situation to model the complexity within and between systems and indicate how changes in one element might flow on to others. It is comprised of themes (social, technical and change management options) networked together in a way that captures their influence and association with each other and also their influence, association and impact on appliance usage and residential peak energy demand. The real value of the model is in creating awareness, understanding and insight into the complexity of residential peak energy demand and in working with this complexity to identify and integrate the social, technical and change management option themes and their impact on appliance usage and residential energy demand at peak times.

    Tattoos have held different meanings throughout history, with particular significance in cultural, social, and clinical contexts. Psychiatrists have long been interested in understanding the relevance of the tattooed body in a clinical or forensic evaluation and in settling on interpretive models that hold reliable value. Some studies have indicated that tattoos may be associated with markers of high-risk behaviors, mental illness diagnosis, and personality disorders. We attempt to provide an updated and comprehensive guide for forensic evaluators, so they can incorporate the observation of tattoos into their assessments with a review of the scientific literature that supports the interpretations and places them in context. The association between tattoos and risk, mental health, or behavioral implications is not as clear or linear as one might initially imagine, and mental health professionals should have a sophisticated understanding of the practice. © 2018 American Academy of Psychiatry and the Law.

    Full Text Available Background The study was carried out within the research “Reading comprehension – typical development and its risks”. The article contains data from a component study focused on 4th grade students with autism spectrum disorder (ASD who were incorporated into a group of readers with reading comprehension development risks. The main aim was to establish whether variable results in children’s reading and comprehension tests relate to the level of understanding of social relations. Participants and procedure We tested 20 students with ASD in two phases: T1 and T2. Each phase consisted of 2 individual sessions. Under the leadership of a research assistant, during each of these sessions a student would carry out the test focused on general intellectual skills, language skills, reading, and reading comprehension. For students with autistic spectrum disorder the Strange Stories test was added in order to ascertain the level of social relations understanding. Results The results in reading and reading comprehension tests among students with ASD varied significantly. Based on a correlation analysis it was found that the Strange Stories results substantially correlate with tests focused on reading, text comprehension and language skill levels. Conclusions Our research proved the following: the Strange Stories test results show that the level to which an individual is able to understand social relations and social behavior is significantly related to his/her ability to comprehend a text. Consequently, this can influence his/her learning skills as well as the quality of life in society. Cultivation of social abilities, social communication and understanding of social situations and relations is therefore necessary for compensation of autistic spectrum disorder expressions.

    What do scientists in the field of preimplantation genetic diagnosis (PGD) and preimplantation genetic screening (PGS) consider to be the future direction of comprehensive embryo testing? Although there are many biological and technical limitations, as well as uncertainties regarding the meaning of genetic variation, comprehensive embryo testing will impact the IVF/PGD practice and a timely ethical reflection is needed. Comprehensive testing using microarrays is currently being introduced in the context of PGD and PGS, and it is to be expected that whole-genome sequencing will also follow. Current ethical and empirical sociological research on embryo testing focuses on PGD as it is practiced now. However, empirical research and systematic reflection regarding the impact of comprehensive techniques for embryo testing is missing. In order to understand the potential of this technology and to be able to adequately foresee its implications, we held an expert panel with seven pioneers in PGD. We conducted an expert panel in October 2011 with seven PGD pioneers from Belgium, The Netherlands, Germany and the UK. Participants expected the use of comprehensive techniques in the context of PGD. However, the introduction of these techniques in embryo testing requires timely ethical reflection as it involves a shift from choosing an embryo without a particular genetic disease (i.e. PGD) or most likely to result in a successful pregnancy (i.e. PGS) to choosing the best embryo based on a much wider set of criteria. Such ethical reflection should take account of current technical and biological limitations and also of current uncertainties with regard to the meaning of genetic variance. However, ethicists should also not be afraid to look into the future. There was a general agreement that embryo testing will be increasingly preceded by comprehensive preconception screening, thus enabling smart combinations of genetic testing. The group was composed of seven participants from

    Integrative oncology, which is generally understood to refer to the use of a combination of complementary medicine therapies in conjunction with conventional cancer treatments, has been defined in different ways, but there is no widely accepted definition. We sought to develop and establish a consensus for a comprehensive definition of the field of integrative oncology. We used a mixed-methods approach that included a literature analysis and a consensus procedure, including an interdisciplinary expert panel and surveys, to develop a comprehensive and acceptable definition for the term "integrative oncology." The themes identified in the literature and from the expert discussion were condensed into a two-sentence definition. Survey respondents had very positive views on the draft definition, and their comments helped to shape the final version. The final definition for integrative oncology is: "Integrative oncology is a patient-centered, evidence-informed field of cancer care that utilizes mind and body practices, natural products, and/or lifestyle modifications from different traditions alongside conventional cancer treatments. Integrative oncology aims to optimize health, quality of life, and clinical outcomes across the cancer care continuum and to empower people to prevent cancer and become active participants before,during, and beyond cancer treatment." This short and comprehensive definition for the term integrative oncology will facilitate a better understanding and communication of this emerging field. This definition will also drive focused and cohesive effort to advance the field of integrative oncology. © The Author 2017. Published by Oxford University Press. All rights reserved.

  4. Transcriptional repressor domain of MBD1 is intrinsically disordered and interacts with its binding partners in a selective manner.

    KAUST Repository

    Hameed, Umar Farook Shahul

    2014-05-09

    Methylation of DNA CpG sites is a major mechanism of epigenetic gene silencing and plays important roles in cell division, development and carcinogenesis. One of its regulators is the 64-residue C-terminal Transcriptional Repressor Domain (the TRD) of MBD1, which recruits several repressor proteins such as MCAF1, HDAC3 and MPG that are essential for the gene silencing. Using NMR spectroscopy, we have characterized the solution structure of the C-terminus of MBD1 (MBD1-c, residues D507 to Q605), which included the TRD (A529 to P592). Surprisingly, the MBD1-c is intrinsically disordered. Despite its lack of a tertiary folding, MBD1-c could still bind to different partner proteins in a selective manner. MPG and MCAF1Δ8 showed binding to both the N-terminal and C-terminal residues of MBD1-c but HDAC3 preferably bound to the C-terminal region. This study reveals how MBD1-c discriminates different binding partners, and thus, expands our understanding of the mechanisms of gene regulation by MBD1.

  6. Multiple effects of consonant manner of articulation and intonation type on F0 in English

    2004-05-01

    In this study we examine how consonant manner of articulation interacts with intonation type in shaping the F0 contours in English. Native speakers of American English read aloud words differing in vowel length, consonant manner of articulation and consonant position in word. They produced each word in either a statement or question carrier. F0 contours of their speech were extracted by measuring every complete vocal period. Preliminary results based on graphic analysis of three speakers' data suggest that there are three distinct consonantal effects: F0 interruption due to devoicing, a large but brief (10-40 ms) F0 raising at the onset of voicing, and a smaller but longer-lasting F0 raising throughout a large proportion of the preceding and following vowels. These effects appear to be imposed on a continuously changing F0 curve that is either rising-falling or falling-rising, depending on whether the carrier sentence is a statement or a question. Further analysis will test the hypothesis that these continuous curves result from local pitch targets that are assigned to individual syllables and implemented with them in synchrony regardless of their segmental composition.

  7. Macrophage migration inhibitory factor activates hypoxia-inducible factor in a p53-dependent manner.

    Directory of Open Access Journals (Sweden)

    Seiko Oda

    Full Text Available BACKGROUND: Macrophage migration inhibitory factor (MIF is not only a cytokine which has a critical role in several inflammatory conditions but also has endocrine and enzymatic functions. MIF is identified as an intracellular signaling molecule and is implicated in the process of tumor progression, and also strongly enhances neovascularization. Overexpression of MIF has been observed in tumors from various organs. MIF is one of the genes induced by hypoxia in an hypoxia-inducible factor 1 (HIF-1-dependent manner. METHODS/PRINCIPAL FINDINGS: The effect of MIF on HIF-1 activity was investigated in human breast cancer MCF-7 and MDA-MB-231 cells, and osteosarcoma Saos-2 cells. We demonstrate that intracellular overexpression or extracellular administration of MIF enhances activation of HIF-1 under hypoxic conditions in MCF-7 cells. Mutagenesis analysis of MIF and knockdown of 53 demonstrates that the activation is not dependent on redox activity of MIF but on wild-type p53. We also indicate that the MIF receptor CD74 is involved in HIF-1 activation by MIF at least when MIF is administrated extracellularly. CONCLUSION/SIGNIFICANCE: MIF regulates HIF-1 activity in a p53-dependent manner. In addition to MIF's potent effects on the immune system, MIF is linked to fundamental processes conferring cell proliferation, cell survival, angiogenesis, and tumor invasiveness. This functional interdependence between MIF and HIF-1alpha protein stabilization and transactivation activity provide a molecular mechanism for promotion of tumorigenesis by MIF.

    Full Text Available The aim of the study was to determine the influence of different concentrations of phytoestrogens biochanin A (BIO A; 20, 40, 50μg ml-1 and daidzein (DAI; 10, 20, 40, 50μg ml-1 on the course of meiotic maturation of pig oocytes. After a 24-hour cultivation, a stage of nuclear maturation was achieved and the areas of cumulus-oocyte complexes (COCs, as an indicator of cumulus expansion, were evaluated. The effects of both contaminants on oocytes were mani - fested from the lowest concentration used. Nuclear maturation was inhibited in a dose-dependent manner in the case of BIO A. Effects of DAI reached a plateau at a concentration of 20μg ml-1.Possible relationship to limited solubility of DAI was excluded because limits of DAI solubility in culture medium were confirmed at 50 μg ml-1.The cumulus expansion was also influenced in a different manner - reduction of the COC’s area by BIO A was dose-dependent, whereas DAI had the strongest effect on CCs in the lowest and highest concentrations used. Both phytoestrogens negatively influence the meiotic maturation of porcine oocytes but there are significant differences in their concrete effects which could relate to the diverse mechanisms of their acting on target cells.

    Nonspecific histone deacetylase (HDAC) inhibition has been shown to facilitate the extinction of drug-seeking behavior in a manner resistant to reinstatement. A key open question is which specific HDAC is involved in the extinction of drug-seeking behavior. Using the selective HDAC3 inhibitor RGFP966, we investigated the role of HDAC3 in extinction and found that systemic treatment with RGFP966 facilitates extinction in mice in a manner resistant to reinstatement. We also investigated whether the facilitated extinction is related to the enhancement of extinction consolidation during extinction learning or to negative effects on performance or reconsolidation. These are key distinctions with regard to any compound being used to modulate extinction, because a more rapid decrease in a defined behavior is interpreted as facilitated extinction. Using an innovative combination of behavioral paradigms, we found that a single treatment of RGFP966 enhances extinction of a previously established cocaine-conditioned place preference, while simultaneously enhancing long-term object-location memory within subjects. During extinction consolidation, HDAC3 inhibition promotes a distinct pattern of histone acetylation linked to gene expression within the infralimbic cortex, hippocampus, and nucleus accumbens. Thus, the facilitated extinction of drug-seeking cannot be explained by adverse effects on performance. These results demonstrate that HDAC3 inhibition enhances the memory processes involved in extinction of drug-seeking behavior.

    Evidence suggests that gender differences appear in a variety of biological and psychological responses to stress and perhaps in coping with acute and chronic illness as well. Dysfunctional parenting is also thought to be involved in the process of coping with stress and illness; hence, the present study aimed to verify whether dysfunctional remembered parenting would influence psychological distress in a gender-specific manner in patients suffering from cancer. Patients attending an outpatient oncology clinic completed the Remembered Relationships with Parents (RRP), Hospital Anxiety and Depression and Spielberger's State-Trait Anxiety Inventory scales and the National Cancer Center Network Distress Thermometer. Although no baseline gender differences were detected, a multivariate analysis confirmed that anxiety and depression symptoms of men and women suffering from cancer are differentially affected by the RRP Control and Alienation scores. Women with remembered parental alienation and overprotection showed significantly more anxiety symptoms than men, whereas men were more vulnerable to remembered alienation than overprotection with regard to the Distress Thermometer scores. These results suggest that remembered dysfunctional parenting is crucially, and in a gender-specific manner, involved in the coping strategy adopted by male and female cancer patients.

  11. A top-down manner-based DCNN architecture for semantic image segmentation.

    Directory of Open Access Journals (Sweden)

    Kai Qiao

    Full Text Available Given their powerful feature representation for recognition, deep convolutional neural networks (DCNNs have been driving rapid advances in high-level computer vision tasks. However, their performance in semantic image segmentation is still not satisfactory. Based on the analysis of visual mechanism, we conclude that DCNNs in a bottom-up manner are not enough, because semantic image segmentation task requires not only recognition but also visual attention capability. In the study, superpixels containing visual attention information are introduced in a top-down manner, and an extensible architecture is proposed to improve the segmentation results of current DCNN-based methods. We employ the current state-of-the-art fully convolutional network (FCN and FCN with conditional random field (DeepLab-CRF as baselines to validate our architecture. Experimental results of the PASCAL VOC segmentation task qualitatively show that coarse edges and error segmentation results are well improved. We also quantitatively obtain about 2%-3% intersection over union (IOU accuracy improvement on the PASCAL VOC 2011 and 2012 test sets.

  12. A comprehensive definition for metabolic syndrome.

    2009-01-01

    The metabolic syndrome refers to the co-occurrence of several known cardiovascular risk factors, including insulin resistance, obesity, atherogenic dyslipidemia and hypertension. These conditions are interrelated and share underlying mediators, mechanisms and pathways. There has been recent controversy about its definition and its utility. In this article, I review the current definitions for the metabolic syndrome and why the concept is important. It identifies a subgroup of patients with shared pathophysiology who are at high risk of developing cardiovascular disease and type 2 diabetes. By considering the central features of the metabolic syndrome and how they are related, we may better understand the underlying pathophysiology and disease pathogenesis. A comprehensive definition for the metabolic syndrome and its key features would facilitate research into its causes and hopefully lead to new insights into pharmacologic and lifestyle treatment approaches.

  13. Music training and emotion comprehension in childhood.

    2012-10-01

    Children and adults with music training score higher on tests of intellectual ability than their peers without training, but it is unclear whether music lessons are associated with social or emotional functioning. We examined whether music training in childhood is predictive of understanding emotions. We administered the Test of Emotion Comprehension (TEC) and a brief IQ test to musically trained and untrained 7- and 8-year-olds. Musically trained children scored higher on IQ and on the TEC even after accounting for demographic variables. Group differences in TEC scores disappeared, however, when IQ scores were held constant. These findings suggest that nonmusical associations with music training are limited to measures of intellectual ability and their correlates.

    Havas, David A; Glenberg, Arthur M; Rinck, Mike

    2007-06-01

    We report a novel finding on the relation of emotion and language. Covert manipulation of emotional facial posture interacts with sentence valence when measuring the amount of time to judge valence (Experiment 1) and sensibility (Experiment 2) of the sentence. In each case, an emotion-sentence compatibility effect is found: Judgment times are faster when facial posture and sentence valence match than when they mismatch. We interpret the finding using a simulation account; that is, emotional systems contribute to language comprehension much as they do in social interaction. Because the effect was not observed on a lexical decision task using emotion-laden words (Experiment 3), we suggest that the emotion simulation affects comprehension processes beyond initial lexical access.

    1975-01-01

    The Atlantic Richfield Hanford Company (ARHCO) has developed comprehensive plans for coping with emergencies ranging from criticality to civil disturbance. A unique notification system provides for immediate contact with key personnel by using a central communications center, crash alarm warning networks, and a continuing telephone cascade notification system. There is also the capability of immediately contacting other contractor key personnel. Certain jobs have been predetermined as necessary for coping with an emergency. An emergency staff consisting of responsible management, with alternates, has been preselected to automatically fill these jobs when notified. Control centers for headquarters and ''field'' are established with telephone and radio communication capabilities and are also supplied with some source materials to assist initiating plans for containing an emergency for recovery. A comprehensive emergency procedures manual has been developed, which contains information of company-wide application and procedures for specific facilities covering almost all accident situations

    We outline a plan for the development of a comprehensive numerical model of tokamaks. The model would consist of a suite of independent, communicating packages describing the various aspects of tokamak performance (core and edge transport coefficients and profiles, heating, fueling, magnetic configuration, etc.) as well as extensive diagnostics. These codes, which may run on different computers, would be flexibly linked by a user-friendly shell which would allow run-time specification of packages and generation of pre- and post-processing functions, including workstation-based visualization of output. One package in particular, the calculation of core transport coefficients via gyrokinetic particle simulation, will become practical on the scale required for comprehensive modelling only with the advent of teraFLOP computers. Incremental effort at LLNL would be focused on gyrokinetic simulation and development of the shell

    1985-01-01

    The conclusion of a comprehensive nuclear test ban is of critical importance for the future of arms limitation and disarmament. As the 1980 report of the Secretary-General concluded, a comprehensive nuclear test ban is regarded as the first and most urgent step towards the cessation of the nuclear arms race and, in particular, of its qualitative aspects. It could serve as an important measure for the non-proliferation of nuclear weapons, both vertical and horizontal. It would have a major arms limitation impact in that it would make it difficult, if not impossible, to develop new designs of nuclear weapons and would also place constraints on the modification of existing weapon designs. The permanent cessation of all nuclear-weapon tests has long been sought by the world community and its achievement would be an event of great international significance

    2014-01-01

    Verbal communication does not rely only on the simple perception of auditory signals. It is rather a parallel and integrative processing of linguistic and non-linguistic information, involving temporal and frontal areas in particular. This review describes the inherent complexity of auditory speech comprehension from a functional-neuroanatomical perspective. The review is divided into two parts. In the first part, structural and functional asymmetry of language relevant structures will be discus. The second part of the review will discuss recent neuroimaging studies, which coherently demonstrate that speech comprehension processes rely on a hierarchical network involving the temporal, parietal, and frontal lobes. Further, the results support the dual-stream model for speech comprehension, with a dorsal stream for auditory-motor integration, and a ventral stream for extracting meaning but also the processing of sentences and narratives. Specific patterns of functional asymmetry between the left and right hemisphere can also be demonstrated. The review article concludes with a discussion on interactions between the dorsal and ventral streams, particularly the involvement of motor related areas in speech perception processes, and outlines some remaining unresolved issues.

    Mounting evidence suggests that neuronal activity influences myelination, potentially allowing for experience-driven modulation of neural circuitry. The degree to which neuronal activity is capable of regulating myelination at the individual axon level is unclear. Here we demonstrate that stimulation of somatosensory axons in the mouse brain increases proliferation and differentiation of oligodendrocyte progenitor cells (OPCs) within the underlying white matter. Stimulated axons display an increased probability of being myelinated compared to neighboring non-stimulated axons, in addition to being ensheathed with thicker myelin. Conversely, attenuating neuronal firing reduces axonal myelination in a selective activity-dependent manner. Our findings reveal that the process of selecting axons for myelination is strongly influenced by the relative activity of individual axons within a population. These observed cellular changes are consistent with the emerging concept that adaptive myelination is a key mechanism for the fine-tuning of neuronal circuitry in the mammalian CNS.

  6. FtsK-dependent XerCD-dif recombination unlinks replication catenanes in a stepwise manner.

    In Escherichia coli, complete unlinking of newly replicated sister chromosomes is required to ensure their proper segregation at cell division. Whereas replication links are removed primarily by topoisomerase IV, XerC/XerD-dif site-specific recombination can mediate sister chromosome unlinking in Topoisomerase IV-deficient cells. This reaction is activated at the division septum by the DNA translocase FtsK, which coordinates the last stages of chromosome segregation with cell division. It has been proposed that, after being activated by FtsK, XerC/XerD-dif recombination removes DNA links in a stepwise manner. Here, we provide a mathematically rigorous characterization of this topological mechanism of DNA unlinking. We show that stepwise unlinking is the only possible pathway that strictly reduces the complexity of the substrates at each step. Finally, we propose a topological mechanism for this unlinking reaction.

The present study examined the effects of parental rearing on dysfunctional attitudes in three areas of life with special attention to gender specificity. The subjects were 665 Japanese healthy volunteers. Dysfunctional attitudes were assessed by the 24-item Dysfunctional Attitude Scale, which has the Achievement, Dependency and Self-control subscales. Perceived parental rearing was assessed by the Parental Bonding Instrument, which has the Care and Protection subscales. Higher scores of the Achievement (β = 0.293, p parents and recipients. Scores of the Self-control subscale were not correlated with paternal or maternal rearing scores. The present study suggests that parental overprotection engenders dysfunctional attitudes about achievement and dependency in a gender-specific manner.

    Critics of current healthcare argue that professionalism, as manifest by etiquette and bedside manners, has been eroding, in part as a consequence of portrayals on television (TV) and in the media. We sought to identify changing patterns of physicians' behaviors as shown on TV (as these interactions have often served as models for physicians-in-training) over the last 30 years. We selected popular TV shows that portrayed practicing physicians and analyzed doctor-family, doctor-doctor, and doctor-nurse interactions as well as methods of disclosing errors to identify changing behavioral trends. We found that difficult news was more commonly delivered while standing, and that handshakes were rarely offered to patients. Male physicians were seen raising their voices toward, disclosing errors to, as well as inappropriately touching, peers or subordinates. In comparison, female physicians were identified as raising their voices toward, disclosing errors to, as well as inappropriately touching, their supervisors. Over the past several decades, official salutations between physicians and nurses have become less common; physicians have started to address nurses solely by their first names. More recently, sexual banter and sexual activity have been portrayed as occurring predominantly between male physicians and female nurses. While shifts in behavioral patterns (in etiquette, bedside manners, and professionalism) of physicians as seen on television have not been radical, potentially concerning trends were identified. Media portrayals may change patients' perceptions of physicians, hospitals, and the health care profession as well as influence behaviors of medical trainees. Moreover, TV and the media can be used as teaching tools about professionalism in healthcare providers. Published by Elsevier Inc.

    We examined the protein anabolic effects of Pro-Stat 64, a high nitrogen-containing, enzyme-hydrolyzed, tryptophan-fortified, collagen protein supplement administrated during hemodialysis, at two different dosing regimens. This was a randomized, controlled, prospective study with 3 different groups: control, single dose of supplementation, and double dose of supplementation. This study was performed at a clinical research center. Six prevalent chronic hemodialysis (HD) patients were enrolled: 5 males, 1 female, 4 African Americans, and 2 Caucasians. Their mean age was 45 +/- 11 years (S.D.). Two patients were diabetic. Protein turnover studies were performed using amino-acid (AA) balance and primed constant infusion of L-(1-(13)C) leucine. Whole-body protein balance was determined according to substrate kinetics. There were no statistically significant difference at any time point between protocols for blood chemistries and hormonal markers, except for minor variations in plasma glucose. All plasma AA groups displayed decreases during a control study, in which no supplementation was given. Compared with the control group, plasma nonessential AA and total AA concentrations were statistically significantly higher during HD after both single and double doses of supplementation. The forearm arteriovenous AA balance was statistically significantly better for essential, nonessential, and total AA uptake after both single-dose and double-dose supplementation compared with the control group, except for nonessential AA, which was significantly better only after a double dose. Whole-body protein breakdown and net protein balance were statistically significantly better during HD with a double-dose administration in a dose-dependent manner, compared with the control and single-dose groups. Oral AA supplementation alone improves whole-body and skeletal muscle protein anabolism in a dose-dependent manner in chronic HD patients. These data should be taken into account during

  10. Investigation of organic matter migrating from polymeric pipes into drinking water under different flow manners.

    Polymeric pipes, such as unplasticized polyvinyl chloride (uPVC) pipes, polypropylene random (PPR) pipes and polyethylene (PE) pipes are increasingly used for drinking water distribution lines. Plastic pipes may include some additives like metallic stabilizers and other antioxidants for the protection of the material during its production and use. Thus, some compounds can be released from those plastic pipes and cast a shadow on drinking water quality. This work develops a new procedure to investigate three types of polymer pipes (uPVC, PE and PPR) with respect to the migration of total organic carbon (TOC) into drinking water. The migration test was carried out in stagnant conditions with two types of migration processes, a continuous migration process and a successive migration process. These two types of migration processes are specially designed to mimic the conditions of different flow manners in drinking water pipelines, i.e., the situation of continuous stagnation with long hydraulic retention times and normal flow status with regular water renewing in drinking water networks. The experimental results showed that TOC release differed significantly with different plastic materials and under different flow manners. The order of materials with respect to the total amount of TOC migrating into drinking water was observed as PE > PPR > uPVC under both successive and continuous migration conditions. A higher amount of organic migration from PE and PPR pipes was likely to occur due to more organic antioxidants being used in pipe production. The results from the successive migration tests indicated the trend of the migration intensity of different pipe materials over time, while the results obtained from the continuous migration tests implied that under long stagnant conditions, the drinking water quality could deteriorate quickly with the consistent migration of organic compounds and the dramatic consumption of chlorine to a very low level. Higher amounts of TOC

    Full Text Available Throughout the United States, many middle and high school students struggle to comprehend science texts for a variety of reasons. Science texts are frequently boring, focused on isolated facts, present too many new concepts at once, and lack the clarity and organization known to improve comprehension. Compounding the problem is that many adolescent readers do not possess effective comprehension strategies, particularly for difficult expository science texts. Some researchers have suggested changing the characteristics of science texts to better assist adolescent readers with understanding, while others have focused on changing the strategies of adolescent readers. In the current paper, we review the literature on selected strategy instruction programs used to improve science text comprehension in middle and high school students and suggest avenues for future research.

    Planetary exploration missions to other worlds, like Mars, can generate a lot of excitement and wonder for the public. The Mars Science Laboratory Mission is one of the latest planetary missions that has intrigued the public perhaps more than most. How can scientists and educational specialists capitalize on the allure of this mission and involve students and teachers in a way that not only shares the story of the mission, but actively engages classrooms with scientists and improves their understanding of the science? The Expedition Earth and Beyond (EEAB) Program [1], facilitated by the Astromaterials Research and Exploration Science (ARES) Directorate Education Program at the NASA Johnson Space Center achieves this by facilitating MSL mission focused classroom connection webinars. Five MSL-focused webinars facilitated through EEAB during the 2012 fall semester engaged almost 3000 students and teachers. Involved STEM experts/role models helped translate the science behind the Mars Science Laboratory mission in a comprehensive, exciting, and engaging manner. These virtual events captured participants attention while increasing their science awareness and understanding of the MSL mission.

    Full Text Available The concerns of the present paper emerge from the single basic question of whether the available histories of the tiger are comprehensive enough to enable an understanding of how this nodular species comprises/contests the power dynamics of the present. Starting with this basic premise, this paper retells a series of events which go to clarify that a nuanced understanding of the manner in which a species serves certain political purposes is not possible by tracking the animal alone. A discourse on endangerment has beginnings in the body and being of species that are remarkably cut off from the tiger-the elephant, birds, and the rhino (and man if we might add-and develops with serious implications for power, resource appropriation, and criminality, over a period of time, before more directly recruiting the tiger itself. If we can refer to this as the intermittent making and unmaking of the endangered, it is by turning to the enunciations of Michel Foucault that we try to canvas a series of events that can be described as animal-criminal processes. The role of such processes in the construction of endangerment, the structuring of space, and shared ideas of man-animal relations is further discussed in this paper.

    The preparation of next generation analyst work requires alternative levels of understanding and new methodological departures from the way current work transpires. Current work practices typically do not provide a comprehensive approach that emphasizes the role of and interplay between (a) cognition, (b) emergent activities in a shared situated context, and (c) collaborative teamwork. In turn, effective and efficient problem solving fails to take place, and practice is often composed of piecemeal, techno-centric tools that isolate analysts by providing rigid, limited levels of understanding of situation awareness. This coupled with the fact that many analyst activities are classified produces a challenging situation for researching such phenomena and designing and evaluating systems to support analyst cognition and teamwork. Through our work with cyber, image, and intelligence analysts we have realized that there is more required of researchers to study human-centered designs to provide for analyst's needs in a timely fashion. This paper identifies and describes how The Living Laboratory Framework can be utilized as a means to develop a comprehensive, human-centric, and problem-focused approach to next generation analyst work, design, and training. We explain how the framework is utilized for specific cases in various applied settings (e.g., crisis management analysis, image analysis, and cyber analysis) to demonstrate its value and power in addressing an area of utmost importance to our national security. Attributes of analyst work settings are delineated to suggest potential design affordances that could help improve cognitive activities and awareness. Finally, the paper puts forth a research agenda for the use of the framework for future work that will move the analyst profession in a viable manner to address the concerns identified.

    Understanding and learning from academic texts involves purposeful, strategic reading. Adolescent readers, particularly poor readers, benefit from explicit instruction in text comprehension strategies, such as text preview, summarization, and comprehension monitoring, as part of a comprehensive reading program. However, strategies are difficult to teach within subject area lessons where content instruction must take primacy. Speech-language pathologists (SLPs) have the expertise and service delivery options to support middle and high school students in learning to use comprehension strategies in their academic reading and learning. This article presents the research evidence on what strategies to teach and how best to teach them, including the use of explicit instruction, spoken interactions around text, cognitive modeling, peer learning, classroom connections, and disciplinary literacy. The article focuses on how to move comprehension strategies from being teaching tools of the SLP to becoming learning tools of the student. SLPs can provide the instruction and support needed for students to learn and apply of this important component of academic reading.

    Efforts to transform health care delivery to improve care have increasingly focused on care integration. However, variation in how integration is defined has complicated efforts to design, synthesize, and compare studies of integration in health care. Evaluations of integration initiatives would be enhanced by describing them according to clear definitions of integration and specifying which empirical relationships they seek to test-whether among types of integration or between integration and outcomes of care. Drawing on previous work, we present a comprehensive theoretical model of relationships between types of integration and propose how to measure them.

    Language learners often spend more time comprehending than producing a new language. However, memory research suggests reasons to suspect that production practice might provide a stronger learning experience than comprehension practice. We tested the benefits of production during language learning and the degree to which this learning transfers to comprehension skill. We taught participants an artificial language containing multiple linguistic dependencies. Participants were randomly assigned to either a production- or a comprehension-learning condition, with conditions designed to balance attention demands and other known production-comprehension differences. After training, production-learning participants outperformed comprehension-learning participants on vocabulary comprehension and on comprehension tests of grammatical dependencies, even when we controlled for individual differences in vocabulary learning. This result shows that producing a language during learning can improve subsequent comprehension, which has implications for theories of memory and learning, language representations, and educational practices.

    Full Text Available Narratives, also called stories, can be found in conversations, children’s play interactions, reading material, and television programs. From infancy to adulthood, narrative comprehension processes interpret events and inform our understanding of physical and social environments. These processes have been extensively studied to ascertain the multifaceted nature of narrative comprehension. From this research we know that three overlapping processes (i.e., knowledge integration, goal structure understanding, and causal inference generation proposed by the constructionist paradigm are necessary for narrative comprehension, narrative comprehension has a predictive relationship with children’s later reading performance, and comprehension processes are generalizable to other contexts. Much of the previous research has emphasized internal and predictive validity; thus, limiting the generalizability of previous findings. We are concerned these limitations may be excluding underrepresented populations from benefits and implications identified by early comprehension processes research. This review identifies gaps in extant literature regarding external validity and argues for increased emphasis on externally valid research. We highlight limited research on narrative comprehension processes in children from low-income and minority populations, and argue for changes in comprehension assessments. Specifically, we argue both on- and off-line assessments should be used across various narrative types (e.g., picture books, televised narratives with traditionally underserved and underrepresented populations. We propose increasing the generalizability narrative comprehension processes research can inform persistent reading achievement gaps, and have practical implications for how children learn from narratives.

    To establish a mathematical formula for choosing the manner of replacement fluid infusion in continuous renal replacement therapy (CRRT), so as to provide the basis for improving the treatment effect. A mathematical formula for choosing the manner of replacement fluid infusion with continuous veno-venous hemofiltration (CVVH) was taken as an example, and it was compared with the result of standard replacement fluid in order to analyze the effect of different manners of infusion. (1) Comparison parameters: the plasma volume ("Vreturn") and some electrolyte concentration ("Creturn") in back way of CRRT ( if other thing was solute, filter coefficient should be 1.0). (2) Research objects: the actual replacement fluid (for example, the most complex should be sorted into A and B type) mode (pre or post) was compared with the standard replacement fluid (the A and B in one). (3) Based on the formula of standard replacement, four equations in different conditions were derived: pre-dilution and post-dilution mode; same direction and same ratio; same direction and different ratio; different direction and same ratio; different direction and different ratio. The calculated results of "Vreturn" (except hematocrit) and "Creturn" were same to the standard only following the rule of same direction and ratio for A and B no matter pre-dilution mode or post-dilution mode, and it was different from the standard in others. In pre-dilution mode and post-dilution mode, it showed: (1) A and B in same direction and different ratio: "Vreturn" and "Creturn" were different from the standard for the alterative ratio of B. (2) A and B in different direction and same ratio: "Vreturn" was same to the standard, but "Creturn" was different from the standard for the completely different and more complex computational formula. (3) A and B in different direction and different ratio: both "Vreturn" and "Creturn" were different from the standard. The different "Vreturn" was due to the different ratio of

    Transcription factor doses are of importance for normal and malignant B-lymphocyte development; however, the understanding of underlying mechanisms and functional consequences of reduced transcription factor levels is limited. We have analyzed progenitor and B-lineage compartments in mice carrying heterozygote mutations in the E2a, Ebf1, or Pax5 gene. Although lymphoid progenitors from Ebf1 or Pax5 heterozygote mice were specified and lineage-restricted in a manner comparable with Wt progenitors, this process was severely impaired in E2a heterozygote mutant mice. This defect was not significantly enhanced upon combined deletion of E2a with Ebf1 or Pax5. Analysis of the pre-B-cell compartment in Ebf1 heterozygote mice revealed a reduction in cell numbers. These cells expressed Pax5 and other B-lineage-associated genes, and global gene expression analysis suggested that the reduction of the pre-B-cell compartment was a result of impaired pre-B-cell expansion. This idea was supported by a reduction in IL2Rα-expressing late pre-B-cells as well as by cell cycle analysis and by the finding that the complexity of the VDJ rearrangement patterns was comparable in Wt and Ebf1(+/-) pre-B-cells, although the number of progenitors was reduced. Heterozygote deletion of Ebf1 resulted in impaired response to IL7 in vitro and reduced expression levels of pre-BCR on the cell surface, providing possible explanations for the observed stage-specific reduction in cellular expansion. Thus, transcription factor doses are critical for specification as well as expansion of B-lymphoid progenitors, providing increased insight into the molecular regulation of B-cell development.

    Full Text Available OBJECTIVE: Habitual chocolate intake was recently found to be associated with lower body weight in three cross-sectional epidemiological studies. Our objective was to assess whether these cross-sectional results hold up in a more rigorous prospective analysis. METHODS: We used data from the Atherosclerosis Risk in Communities cohort. Usual dietary intake was assessed by questionnaire at baseline (1987-98, and after six years. Participants reported usual chocolate intake as the frequency of eating a 1-oz (~28 g serving. Body weight and height were measured at the two visits. Missing data were replaced by multiple imputation. Linear mixed-effects models were used to evaluate cross-sectional and prospective associations between chocolate intake and adiposity. RESULTS: Data were from 15,732 and 12,830 participants at the first and second visit, respectively. More frequent chocolate consumption was associated with a significantly greater prospective weight gain over time, in a dose-response manner. For instance, compared to participants who ate a chocolate serving less often than monthly, those who ate it 1-4 times a month and at least weekly experienced an increase in Body Mass Index (kg/m2 of 0.26 (95% CI 0.08, 0.44 and 0.39 (0.23, 0.55, respectively, during the six-year study period. In cross-sectional analyses the frequency of chocolate consumption was inversely associated with body weight. This inverse association was attenuated after excluding participants with preexisting obesity-related illness. Compared to participants without such illness, those with it had higher BMI and reported less frequent chocolate intake, lower caloric intake, and diets richer in fruits and vegetables. They tended to make these dietary changes after becoming ill. CONCLUSIONS: Our prospective analysis found that a chocolate habit was associated with long-term weight gain, in a dose-response manner.

    Lay Abstract Children with autism produce few wh-questions, compared to their typically developing peers. It is unclear if this is because of social-pragmatic difficulties, or if they have not yet learned the grammar for asking wh-questions. If children do not know how to use grammatical rules to produce questions, they might simply repeat sentences that they have heard without completely understanding them first. We visited the homes of 15 children with autism and 18 typically developing children with similar language abilities, across a three-year period. At each visit, children watched a video that depicted an apple hitting a flower and keys hitting a book. The children were then shown the items side-by-side on the screen and the audio asked “what hit the flower?” and “what did the keys hit?” We filmed the children’s eye movements and analyzed how long they looked at the named item, compared to when they heard “where is the flower/keys?” At each visit, we also filmed a 30-minute mother-child play session and analyzed the types of questions that the children asked. Children with autism showed comprehension of wh-questions at a later age than typically developing children, but at a similar level of overall language development. Neither group produced wh-questions before they had demonstrated that they understood the underlying grammatical rules. Therefore, children with autism seem to process wh-questions in the same way as their typically developing peers, just at a later age. This paper discusses the implications of our findings for the language development of children with autism. Scientific Abstract Children with autism (ASD) rarely produce wh-questions (e.g., “What hit the book?”) in naturalistic speech. It is unclear if this is due to social-pragmatic difficulties, or if grammatical deficits are also involved. If grammar is impaired, production of wh-questions by rote memorization might precede comprehension of similar forms. In a

    Title 44 United States Code, ''Public Printing and Documents,'' regulations cited in the General Services Administration's (GSA) ''Federal Information Resources Management Regulations'' (FIRMR), Part 201-9, ''Creation, Maintenance, and Use of Records,'' and regulation issued by the National Archives and Records Administration (NARA) in 36 CFR Chapter XII, Subchapter B, ''Records Management,'' require each agency to prepare and issue a comprehensive records disposition schedule that contains the NARA approved records disposition schedules for records unique to the agency and contains the NARA's General Records Schedules for records common to several or all agencies. The approved records disposition schedules specify the appropriate duration of retention and the final disposition for records created or maintained by the NRC. NUREG-0910, Rev. 2, contains ''NRC's Comprehensive Records Disposition Schedule,'' and the original authorized approved citation numbers issued by NARA. Rev. 2 totally reorganizes the records schedules from a functional arrangement to an arrangement by the host office. A subject index and a conversion table have also been developed for the NRC schedules to allow staff to identify the new schedule numbers easily and to improve their ability to locate applicable schedules

    Understanding sustainability is one of the significant implementation science challenges. One of the big challenges in researching sustainability is the lack of consistent definitions in the literature. Most implementation studies do not present a definition of sustainability, even when assessing sustainability. The aim of the current study was to systematically develop a comprehensive definition of sustainability based on definitions already used in the literature. We searched for knowledge syntheses of sustainability and abstracted sustainability definitions from the articles identified through any relevant systematic and scoping reviews. The constructs in the abstracted sustainability definitions were mapped to an existing definition. The comprehensive definition of sustainability was revised to include emerging constructs. We identified four knowledge syntheses of sustainability, which identified 209 original articles. Of the 209 articles, 24 (11.5%) included a definition of sustainability. These definitions were mapped to three constructs from an existing definition, and nine new constructs emerged. We reviewed all constructs and created a revised definition: (1) after a defined period of time, (2) a program, clinical intervention, and/or implementation strategies continue to be delivered and/or (3) individual behavior change (i.e., clinician, patient) is maintained; (4) the program and individual behavior change may evolve or adapt while (5) continuing to produce benefits for individuals/systems. All 24 definitions were remapped to the comprehensive definition (percent agreement among three coders was 94%). Of the 24 definitions, 17 described the continued delivery of a program (70.8%), 17 mentioned continued outcomes (70.8%), 13 mentioned time (54.2%), 8 addressed the individual maintenance of a behavior change (33.3%), and 6 described the evolution or adaptation (25.0%). We drew from over 200 studies to identify 24 existing definitions of sustainability

  2. Cytoplasmic Dynein Transports Axonal Microtubules in a Polarity-Sorting Manner

    Full Text Available Axonal microtubules are predominantly organized into a plus-end-out pattern. Here, we tested both experimentally and with computational modeling whether a motor-based polarity-sorting mechanism can explain this microtubule pattern. The posited mechanism centers on cytoplasmic dynein transporting plus-end-out and minus-end-out microtubules into and out of the axon, respectively. When cytoplasmic dynein was acutely inhibited, the bi-directional transport of microtubules in the axon was disrupted in both directions, after which minus-end-out microtubules accumulated in the axon over time. Computational modeling revealed that dynein-mediated transport of microtubules can establish and preserve a predominantly plus-end-out microtubule pattern as per the details of the experimental findings, but only if a kinesin motor and a static cross-linker protein are also at play. Consistent with the predictions of the model, partial depletion of TRIM46, a protein that cross-links axonal microtubules in a manner that influences their polarity orientation, leads to an increase in microtubule transport.

    Parkinson's disease (PD) is a movement disorder caused by the loss of dopaminergic innervation, particularly to the striatum. PD patients often exhibit sensory impairments, yet the underlying network mechanisms are unknown. Here we examined how dopamine (DA) depletion affects sensory processing in the mouse striatum. We used the optopatcher for online identification of direct and indirect pathway projection neurons (MSNs) during in vivo whole-cell recordings. In control mice, MSNs encoded the laterality of sensory inputs with larger and earlier responses to contralateral than ipsilateral whisker deflection. This laterality coding was lost in DA-depleted mice due to adaptive changes in the intrinsic and synaptic properties, mainly, of direct pathway MSNs. L-DOPA treatment restored laterality coding by increasing the separation between ipsilateral and contralateral responses. Our results show that DA depletion impairs bilateral tactile acuity in a pathway-dependent manner, thus providing unexpected insights into the network mechanisms underlying sensory deficits in PD.

    Monocyte chemoattractant protein-1 (MCP-1) is a chemokine that plays a critical role in the recruitment and activation of leukocytes. Here, we describe that multinuclear osteoclast formation was significantly inhibited in cells derived from MCP-1-deficient mice. MCP-1 has been implicated in the regulation of osteoclast cell-cell fusion; however defects of multinuclear osteoclast formation in the cells from mice deficient in DC-STAMP, a seven transmembrane receptor essential for osteoclast cell-cell fusion, was not rescued by recombinant MCP-1. The lack of MCP-1 in osteoclasts resulted in a down-regulation of DC-STAMP, NFATc1, and cathepsin K, all of which were highly expressed in normal osteoclasts, suggesting that osteoclast differentiation was inhibited in MCP-1-deficient cells. MCP-1 alone did not induce osteoclastogenesis, however, the inhibition of osteoclastogenesis in MCP-1-deficient cells was restored by addition of recombinant MCP-1, indicating that osteoclastogenesis was regulated in an autocrine/paracrine manner by MCP-1 under the stimulation of RANKL in osteoclasts.

    APELA is a small, secreted peptide that can function as a ligand for the G-protein coupled receptor, Apelin Receptor (APLNR, APJ). APELA plays an essential role in endoderm differentiation and cardiac development during embryogenesis. We investigated whether APELA exerts any functions in cancer progression. The Cancer Genome Atlas (TCGA) RNA sequencing datasets, microarray from an OCCC mouse model, and RNA isolated from fresh frozen and FFPE patient tissue were used to assess APELA expression. APELA knockout ovarian clear cell carcinoma (OCCC) cell lines were generated using CRISPR/Cas9. APELA was expressed in various ovarian cancer histotypes and was especially elevated in OCCC. Disruption of APELA expression in OCCC cell lines suppressed cell growth and migration, and altered cell-cycle progression. Moreover, addition of human recombinant APELA peptide to the OCCC cell line OVISE promoted cell growth and migration. Interestingly, OVISE cells do not express APLNR, suggesting that APELA can function through an APLNR-independent pathway. Furthermore, APELA affected cell growth and cell cycle progression in a p53-dependent manner. In addition, APELA knockdown induced p53 expression in cancer cell lines. Our findings uncover a potential oncogenic role for APELA in promoting ovarian tumour progression and provide a possible therapeutic strategy in ovarian cancer by targeting APELA.

  6. On Distributional Features of Adverbial Modifier of Manner in Typologically Different Languages: A Case Study

    Directory of Open Access Journals (Sweden)

    Mirzayeva Intizar Gahraman

    2017-12-01

    Full Text Available The study aims to analyze the distributional features of adverbial modifier of manner in two languages that are typologically and genealogically different: English and Azerbaijani. Although the issue has been focused in these languages separately from various angles including semantic, syntactic and prosodic perspectives, there is a gap in the domain of comparative studies. In this regard, syntax is of special importance. Syntactic analysis reveals that in the both languages sentence members are not distributed randomly. In other words, their distribution within the sentence is regulated by certain rules. Each of the sentence members, entering the sentence structure in the syntagmatic order, establishing coordination with sentence members coming before or after it, turns to the bearer of the intended semantic or grammatical functions. Analyses of grammatical forms of the sentences in the English and Azerbaijani sentences show that alongside the universal features which are common for the grammatical forms in sentences of each language, these languages possess distinctive features as well.

  7. Fesselin is a target protein for calmodulin in a calcium-dependent manner

    International Nuclear Information System (INIS)

    2004-01-01

    Fesselin is a basic protein isolated from smooth muscle which binds G-actin and accelerates its polymerization as well as cross-links assembled filaments [J. Muscle Res. Cell Motil. 20 (1999) 539; Biochemistry 40 (2001) 14252]. In this report experimental evidence is provided for the first time proving that fesselin can interact with calmodulin in a Ca 2+ -dependent manner in vitro. Using ion exchange, followed by calmodulin-affinity chromatography, enabled us to simplify and shorten the fesselin preparation procedure and increase its yield by about three times in comparison to the procedure described by Leinweber et al. [J. Muscle Res. Cell Motil. 20 (1999) 539]. Fesselin interaction with dansyl-labelled calmodulin causes a 2-fold increase in maximum fluorescence intensity of the fluorophore and a 21 nm blue shift of the spectrum. The transition of complex formation between fesselin and calmodulin occurs at submicromolar concentration of calcium ions. The dissociation constant of fesselin Ca 2+ /calmodulin complexes amounted to 10 -8 M. The results suggest the existence of a direct link between Ca 2+ /calmodulin and fesselin at the level of actin cytoskeleton dynamics in smooth muscle

    The aim of the present study is to evaluate whether circadian locomotor activity, and the daily profile of plasma parameters related to metabolic syndrome (nutrients: glucose and triacylglycerides, and hormones: insulin and leptin), differ between male and female Neotomodon alstoni mice, both lean and obese. Young adult animals were captured in the field and kept at the laboratory animal facility. After 6 to 7 months feeding the animals ad libitum with a regular diet for laboratory rodents, 50-60% of mice became obese. Comparisons between sexes indicated that lean females were more active than males; however obese females reduced their nocturnal activity either in LD or DD, and advanced the phase of their activity-onset with respect to lights off. No differences in food intake between lean and obese mice, either during the day or night, were observed. Daily profiles of metabolic syndrome-related plasma parameters showed differences between sexes, and obesity was associated with increased values, especially leptin (500% in females and 273% in males) and insulin (150% in both females and males), as compared with lean mice. Our results indicate that lean mice display behavioral and endocrine differences between sexes, and obesity affects the parameters tested in a sex-dependent manner. The aforementioned leads us to propose N. alstoni, studied in captivity, could be an interesting model for the study of sex differences in the effects of obesity. Copyright © 2011 Elsevier Inc.

    Mechanical ventilation (MV) is a therapeutic intervention widely used in the clinic to assist patients that have difficulty breathing due to lung edema, trauma, or general anesthesia. However, MV causes ventilator-induced lung injury (VILI), a condition characterized by increased permeability of the alveolar-capillary barrier that results in edema, hemorrhage, and neutrophil infiltration, leading to exacerbated lung inflammation and oxidative stress. This study explored the feasibility of using bixin, a canonical NRF2 inducer identified during the current study, to ameliorate lung damage in a murine VILI model. In vitro, bixin was found to activate the NRF2 signaling pathway through blockage of ubiquitylation and degradation of NRF2 in a KEAP1-C151 dependent manner; intraperitoneal (IP) injection of bixin led to pulmonary upregulation of the NRF2 response in vivo. Remarkably, IP administration of bixin restored normal lung morphology and attenuated inflammatory response and oxidative DNA damage following MV. This observed beneficial effect of bixin derived from induction of the NRF2 cytoprotective response since it was only observed in Nrf2(+/+) but not in Nrf2(-/-) mice. This is the first study providing proof-of-concept that NRF2 activators can be developed into pharmacological agents for clinical use to prevent patients from lung injury during MV treatment.

    This paper examines the idea that metaphor is a basic cognitive tool from a Wittgensteinian point of view. One specific aspect of Wittgenstein’s legacy is explored, namely his account of verbal understanding. Two interconnected and notoriously difficult features of this account are highlighted and discussed: the idea that linguistic understanding is not an event or a process, but an “abiding condition” (Philosophical Investigations, §143-84; and the idea that neither the meaning of a linguistic expression nor our understanding of it can ever go beyond our capacity of explaining it (Philosophical Investigations, §75. This perspective is shown to be particularly apt in reflecting upon the virtues of metaphor as a means of understanding, especially because it allows for the avoidance of both essentialist and skeptical accounts.

    To reflect on nursing supervision as a management tool for care comprehensiveness by nurses, considering its potential and limits in the current scenario. A reflective study based on discourse about nursing supervision, presenting theoretical and practical concepts and approaches. Limits on the exercise of supervision are related to the organization of healthcare services based on the functional and clinical model of care, in addition to possible gaps in the nurse training process and work overload. Regarding the potential, researchers emphasize that supervision is a tool for coordinating care and management actions, which may favor care comprehensiveness, and stimulate positive attitudes toward cooperation and contribution within teams, co-responsibility, and educational development at work. Nursing supervision may help enhance care comprehensiveness by implying continuous reflection on including the dynamics of the healthcare work process and user needs in care networks. refletir a supervisão de enfermagem como instrumento gerencial do enfermeiro para integralidade do cuidado, considerando suas potencialidades e limitações no cenário atual. estudo reflexivo baseado na formulação discursiva sobre a supervisão de enfermagem, apresentando conceitos e enfoques teóricos e/ou práticos. limitações no exercício da supervisão estão relacionadas à organização dos serviços de saúde embasada no modelo funcional e clínico de atenção, assim como possíveis lacunas no processo de formação do enfermeiro e sobrecarga de trabalho.

  1. Towards a Comprehensive Catalog of Volcanic Seismicity

    Science.gov (United States)

    Thompson, G.

    2014-12-01

    Catalogs of earthquakes located using differential travel-time techniques are a core product of volcano observatories, and while vital, they represent an incomplete perspective of volcanic seismicity. Many (often most) earthquakes are too small to locate accurately, and are omitted from available catalogs. Low frequency events, tremor and signals related to rockfalls, pyroclastic flows and lahars are not systematically catalogued, and yet from a hazard management perspective are exceedingly important. Because STA/LTA detection schemes break down in the presence of high amplitude tremor, swarms or dome collapses, catalogs may suggest low seismicity when seismicity peaks. We propose to develop a workflow and underlying software toolbox that can be applied to near-real-time and offline waveform data to produce comprehensive catalogs of volcanic seismicity. Existing tools to detect and locate phaseless signals will be adapted to fit within this framework. For this proof of concept the toolbox will be developed in MATLAB, extending the existing GISMO toolbox (an object-oriented MATLAB toolbox for seismic data analysis). Existing database schemas such as the CSS 3.0 will need to be extended to describe this wider range of volcano-seismic signals. WOVOdat may already incorporate many of the additional tables needed. Thus our framework may act as an interface between volcano observatories (or campaign-style research projects) and WOVOdat. We aim to take the further step of reducing volcano-seismic catalogs to sets of continuous metrics that are useful for recognizing data trends, and for feeding alarm systems and forecasting techniques. Previous experience has shown that frequency index, peak frequency, mean frequency, mean event rate, median event rate, and cumulative magnitude (or energy) are potentially useful metrics to generate for all catalogs at a 1-minute sample rate (directly comparable with RSAM and similar metrics derived from continuous data). Our framework

    The field of antibiotic drug discovery and the monitoring of new antibiotic resistance elements have yet to fully exploit the power of the genome revolution. Despite the fact that the first genomes sequenced of free living organisms were those of bacteria, there have been few specialized bioinformatic tools developed to mine the growing amount of genomic data associated with pathogens. In particular, there are few tools to study the genetics and genomics of antibiotic resistance and how it impacts bacterial populations, ecology, and the clinic. We have initiated development of such tools in the form of the Comprehensive Antibiotic Research Database (CARD; http://arpcard.mcmaster.ca). The CARD integrates disparate molecular and sequence data, provides a unique organizing principle in the form of the Antibiotic Resistance Ontology (ARO), and can quickly identify putative antibiotic resistance genes in new unannotated genome sequences. This unique platform provides an informatic tool that bridges antibiotic resistance concerns in health care, agriculture, and the environment. PMID:23650175

  5. R7T7 glass alteration mechanism in an aqueous closed system: understanding and modelling the long term alteration kinetic; Etude des mecanismes d'alteration par l'eau du verre R7T7 en milieu confine: comprehension et modelisation de la cinetique residuelle

    Energy Technology Data Exchange (ETDEWEB)

    Chave, T

    2007-10-15

    The long term alteration rate of the French R7T7 nuclear glass has been investigated since many years because it will define the overall resistance of the radionuclide containment matrix. Recent studies have shown that the final rate remains constant or is slightly decreasing with time. It never reaches zero. Though this residual rate is very low, only 5 nm per year at 50 C, it would be the dominant alteration phenomenon in a geological repository. Two mechanisms are suggested for explaining such behaviour: diffusion in solution of elements from glass through an amorphous altered layer and precipitation of neo-formed phases. The diffusion processes are in agreement with a solid state diffusion mechanism and can lead to secondary phase precipitation due to solution concentration increases. Observed phases are mainly phyllosilicates and zeolites, in specific conditions. Phyllosilicates are expected to maintain the residual kinetic rate whereas alteration resumption could be observed in presence of zeolites at very high pH or temperature (10.5 at 90 C or temperature above 150 C). Both diffusion and neo-formed phase precipitation have been investigated in order to better understand their impact on the residual alteration rate and have then been modelled by a calculation code, coupling chemistry and transport, in order to be able to better anticipate the long term behaviour of the glass R7T7 in an aqueous closed system.

    Full Text Available http://dx.doi.org/10.5007/2175-8026.2012n63p69   Experimental studies point that different factors can influence reading comprehension, such as the topic, text type, reading task, and others. The advances in technologies for the past decades have provided researchers with several possibilities to investigate what goes on in one’s brain since their eyes meet the page until comprehension is achieved. Since the mid-80’s, numerous studies have been conducted with the use of the electroencephalogram (EEG to investigate the process of reading, through the analysis of different components – n400, n100 or n1, P2, among others. These components reveal, for example, how the brain integrates the meaning of a specific word in the semantic context of a given sentence.  based on previous studies, which demonstrate that different types of words affect cognitive load, this paper aims at investigating how the brain processes function and content words inserted in expository and narrative texts with suitable / unsuitable conclusions. results showed that the type of text and word influence the cognitive load in different scalp areas (midline, right and left hemispheres. The  n1s were more pronounced to the content words inserted in narrative texts and to the function words inserted in the expository type of texts, corroborating former studies.

    The Forkhead transcription factor FOXA2 plays a fundamental role in controlling metabolic homeostasis in the liver during fasting. The precise molecular regulation of FOXA2 in response to nutrients is not fully understood. Here, we studied whether FOXA2 could be controlled at a post-translational level by acetylation. By means of LC-MS/MS analyses, we identified five acetylated residues in FOXA2. Sirtuin family member SIRT1 was found to interact with and deacetylate FOXA2, the latter process being dependent on the NAD+-binding catalytic site of SIRT1. Deacetylation by SIRT1 reduced protein stability of FOXA2 by targeting it towards proteasomal degradation, and inhibited transcription from the FOXA2-driven G6pase and CPT1a promoters. While mutation of the five identified acetylated residues weakly affected protein acetylation and stability, mutation of at least seven additional lysine residues was required to abolish acetylation and reduce protein levels of FOXA2. The importance of acetylation of FOXA2 became apparent upon changes in nutrient levels. The interaction of FOXA2 and SIRT1 was strongly reduced upon nutrient withdrawal in cell culture, while enhanced Foxa2 acetylation levels were observed in murine liver in vivo after starvation for 36 hours. Collectively, this study demonstrates that SIRT1 controls the acetylation level of FOXA2 in a nutrient-dependent manner and in times of nutrient shortage the interaction between SIRT1 and FOXA2 is reduced. As a result, FOXA2 is protected from degradation by enhanced acetylation, hence enabling the FOXA2 transcriptional program to be executed to maintain metabolic homeostasis.

    Objectives : There is insufficient evidence regarding the potential risk of mobile phone use on mental health. Therefore, the aim of this research was to examine the relationship between mobile phone use and mental health by measuring the levels of depression, anxiety, and stress among university students in Serbia and Italy. Methods : This cross-sectional study was carried out at two distinguished universities in Serbia and Italy from March to May of the 2015/2016 academic year and included 785 students of both genders. The questionnaire was compiled and developed from different published sources regarding the manner and intensity of mobile phone use, along with the Depression Anxiety Stress Scale (DASS 42) for measuring psychological health. The statistical analysis of the data included the application of binary logistic regression and correlation tests. Results: Statistical analysis indicates that anxiety symptoms are somewhat more present in younger students (odds ratio (OR) = 0.86, 95% confidence interval (CI): 0.76-0.96), in those who send more text messages SMSs (OR = 1.15, 95% CI: 1.11-1.31), and in those who browse the internet less frequently (OR = 0.84, 95% CI: 0.73-0.95). Stress is more common in students who make fewer calls a day (OR = 0.79, 95% CI: 0.64-0.97), as well in those who spend more time talking on the mobile phone per day (OR = 1.28, 95% CI: 1.12-1.56). The strongest predictor of high stress levels was keeping the mobile phone less than 1 m away during sleeping (OR = 1.48, 95% CI: 1.12-2.08). Conclusions: The results indicated that the intensity and modality of mobile phone use could be a factor that can influence causal pathways leading to mental health problems in the university student population.

    Full Text Available Sympathetic nervous system stimulation-induced β-adrenergic signal transduction is known to induce bone loss and increase of osteoclast activity. Although isoproterenol, a nonspecific β-adrenergic receptor agonist, has been shown to increase receptor activator of NF-κB ligand (RANKL, the details of the regulatory mechanisms remain unclear. In the present study, we investigated the role of the nuclear factor of activated T-cells (NFAT in isoproterenol-induced RANKL expression in C2C12 and in primary cultured mouse calvarial cells. Isoproterenol increased nuclear factor of activated T-cells cytoplasmic 1 (NFATc1 and RANKL expressions at both mRNA and protein levels and increased NFAT reporter activity. NFATc1 knockdown blocked isoproterenol-mediated RANKL expression. Isoproterenol also promoted cAMP response element-binding protein 1 (CREB1 and activating transcription factor 4 (ATF4 phosphorylation. Isoproterenol-mediated transcriptional activation of NFAT was blocked by protein kinase A (PKA inhibitor H89. Isoproterenol-induced CREB1, ATF4, NFATc1, and RANKL expressions were suppressed by H89. Mutations in cAMP response element-like or NFAT-binding element suppressed isoproterenol-induced RANKL promoter activity. Chromatin immunoprecipitation analysis demonstrated that isoproterenol increased NFAT-binding and ATF4-binding activities on the mouse RANKL promoter, but did not increase CREB1-binding activity. Association of NFATc1 and ATF4 was not observed in a co-immunoprecipitation study. ATF4 knockdown suppressed isoproterenol-induced NFAT binding to the RANKL promoter, whereas NFATc1 knockdown did not suppress isoproterenol-induced ATF4 binding to the RANKL promoter. ATF4 knockdown suppressed isoproterenol-induced expressions of NFATc1 and RANKL. These results suggest that isoproterenol increases RANKL expression in an ATF4/NFATc1-dependent manner.

    Temporomandibular joint (TMJ) inflammation is a potential risk factor of osteoarthritis (OA) but the detailed degenerative changes in the inflamed TMJ remain unclear. In this study, we evaluated the changes of condylar cartilage and subchondral bone in rat inflamed TMJ induced by Freund's complete adjuvant (CFA). Articular cavity was injected with CFA and the TMJ samples were collected 1, 2, 3, and 4-week post-injection. Hematoxylin & Eosin (H&E) staining, toluidine blue (TB) staining, Safranin O (S.O) staining, Masson trichrome staining and micro-CT were used to assess TMJ degeneration during inflammation. Osteoclast and osteoblast activities were analyzed by tartrate-resistant acid phosphatase (TRAP) staining and osteocalcin (OCN) immunohistochemistry staining respectively. The expression of receptor activator of NF-kB ligand (RANKL) and osteoprotegerin (OPG) in condylar cartilage and subchondral bone was also evaluated through immunohistochemistry and RANKL/OPG ratio was evaluated. Reduced cartilage thickness, decreased number of chondrocytes, and down-regulated proteoglycan expression were observed in the condylar cartilage in the inflamed TMJ. Enhanced osteoclast activity, and expanded bone marrow cavity were reached the peak in the 2-week after CFA-injection. Meanwhile the RANKL/OPG ratio in the cartilage and subchondral bone also increased in the 2-week CFA-injection. Immature, unmineralized new bones with irregular trabecular bone structure, atypical condylar shape, up-regulated OCN expression, and decreased bone mineral density (BMD) were found in the inflamed TMJ. The time-dependent degeneration manner of TMJ cartilage and subchondral bone was found in CFA-induced arthritis rat model. The degeneration in the TMJ with inflammation might be a risk factor and should be concerned.

    Full Text Available AMP protein kinase (AMPK plays an important role in food intake and energy metabolism, which are synchronized to the light-dark cycle. In vitro, AMPK affects the circadian rhythm by regulating at least two clock components, CKIα and CRY1, via direct phosphorylation. However, it is not known whether the catalytic activity of AMPK actually regulates circadian rhythm in vivo.THE CATALYTIC SUBUNIT OF AMPK HAS TWO ISOFORMS: α1 and α2. We investigate the circadian rhythm of behavior, physiology and gene expression in AMPKα1-/- and AMPKα2-/- mice. We found that both α1-/- and α2-/- mice are able to maintain a circadian rhythm of activity in dark-dark (DD cycle, but α1-/- mice have a shorter circadian period whereas α2-/- mice showed a tendency toward a slightly longer circadian period. Furthermore, the circadian rhythm of body temperature was dampened in α1-/- mice, but not in α2-/- mice. The circadian pattern of core clock gene expression was severely disrupted in fat in α1-/- mice, but it was severely disrupted in the heart and skeletal muscle of α2-/- mice. Interestingly, other genes that showed circadian pattern of expression were dysreguated in both α1-/- and α2-/- mice. The circadian rhythm of nicotinamide phosphoryl-transferase (NAMPT activity, which converts nicotinamide (NAM to NAD+, is an important regulator of the circadian clock. We found that the NAMPT rhythm was absent in AMPK-deficient tissues and cells.This study demonstrates that the catalytic activity of AMPK regulates circadian rhythm of behavior, energy metabolism and gene expression in isoform- and tissue-specific manners.

    Hepatitis C virus (HCV) is a major human pathogen that causes many serious diseases, including acute and chronic hepatitis, cirrhosis and hepatocellular carcinoma. Treatments for this virus are inadequate, and improved antiviral therapies are necessary. Although the precise mechanisms regulating HCV entry into hepatic cells are still unknown, the low-density lipoprotein receptor (LDLR) has been shown to be essential for entry of infectious HCV particles. Liver X receptors (LXR) were recently reported to control LDLR expression through the regulation of the expression of the Idol (inducible degrader of the LDLR) protein, which could trigger the ubiquitination and degradation of LDLR. In this study, we analyzed the antiviral effect of Idol in vitro. The results demonstrated that Huh7.5.1 cells that exogenously expressed Idol were resistant to HCV infection. Next, the treatment of HCV-infected Huh7.5.1 cells with either synthetic LXR agonists (GW3965 or T0901317) or the natural LXR ligand 24(S),25-epoxycholesterol inhibited HCV infection in a dose-dependent manner. Furthermore, a combination of LXR agonists and HCV RNA replication inhibitors exerted additive effects against HCV, as revealed by isobologram analysis. In conclusion, our data indicate that molecules such as LXR agonists, which could stimulate the expression of Idol, represent a new class of potential anti-HCV compounds, and these compounds could be developed for therapeutic use against HCV infection, either as a monotherapy, or in combination with other anti-HCV drugs.

    Epidemiological studies indicate that caffeine consumption reduces the risk of Parkinson's disease (PD) in men, and antagonists of the adenosine 2A receptor ameliorate the motor symptoms of PD. These findings motivated us to identify proteins whose expression is regulated by caffeine in a sexually dimorphic manner. Using mass spectroscopy, we found that Cox7c, a nuclear-encoded subunit of the mitochondrial enzyme cytochrome oxidase, is up-regulated in the striatum of male but not female mice after receiving a single dose of caffeine. The expression of two other Cox subunits, Cox1 and Cox4, was also stimulated by caffeine in a male-specific fashion. This up-regulation of Cox subunits by caffeine was accompanied by an increase in Cox enzyme activity in the male striatum. Caffeine-induced stimulation of Cox expression and activity were reproduced using the adenosine 2A receptor (A2AR)-specific antagonist 5-amino-7-(2-phenylethyl)-2-(2-furyl)-pyrazolo[4,3-epsilon]-1,2,4-triazolo[1,5-c]pyrimidine (SCH58261), and coadministration of the A2AR-specific agonist 2-[p-(2-carboxyethyl)phenethylamino]-5'-N-ethylcarboxamidoadenosine (CGS21680) counteracted the elevation of Cox expression and activity by caffeine. Caffeine also increased Cox activity in PC-12 cells. In contrast, small interfering RNA (siRNA) knockdown of Cox7c expression in PC-12 cells blunted Cox activity, and this was counteracted by caffeine treatment. Caffeine was also found to increase Cox7c mRNA expression in the striatum and in PC-12 cells. This occurred at the level of transcription and was mediated by a segment of the Cox7c promoter. Overall, these findings indicate that cytochrome oxidase is a metabolic target of caffeine and that stimulation of Cox activity by caffeine via blockade of A2AR signaling may be an important mechanism underlying the therapeutic benefits of caffeine in PD.

  15. Neuron-astrocyte interaction enhance GABAergic synaptic transmission in a manner dependent on key metabolic enzymes.

    Full Text Available GABA is the major inhibitory neurotransmitter in the adult brain and mechanisms of GABAergic inhibition have been intensely investigated in the past decades. Recent studies provided evidence for an important role of astrocytes in shaping GABAergic currents. One of the most obvious, but yet poorly understood, mechanisms of the cross-talk between GABAergic currents and astrocytes is metabolism including neurotransmitter homeostasis. In particular, how modulation of GABAergic currents by astrocytes depends on key enzymes involved in cellular metabolism remains largely unknown. To address this issue, we have considered two simple models of neuronal cultures: nominally astrocyte-free neuronal culture (NC and neuronal-astrocytic co-cultures (ANCC and miniature Inhibitory Postsynaptic Currents (mIPSCs were recorded in control conditions and in the presence of respective enzyme blockers. We report that enrichment of neuronal culture with astrocytes results in a marked increase in mIPSC frequency. This enhancement of GABAergic activity was accompanied by increased number of GAD65 and vGAT puncta, indicating that at least a part of the frequency enhancement was due to increased number of synaptic contacts. Inhibition of glutamine synthetase (with MSO strongly reduced mIPSC frequency in ANCC but had no effect in NC. Moreover, treatment of ANCC with inhibitor of glycogen phosphorylase (BAYU6751 or with selective inhibitor of astrocytic Krebs cycle,fluoroacetate, resulted in a marked reduction of mIPSC frequency in ANCC having no effect in NC. We conclude that GABAergic synaptic transmission strongly depends on neuron-astrocyte interaction in a manner dependent on key metabolic enzymes as well as on the Krebs cycle.

The Memorandum of Understanding allows all involved to specifically understand that they are agreeing to the same thing and the terms are clearly identified. It also includes the clear distinction of functions and the level of involvement of the agencies involved. Specifically, a Memorandum of Understanding gives a chance to all of those involved in the agreement to see on paper as to what they all have agreed to.

  18. The validation and clinical implementation of BRCAplus: a comprehensive high-risk breast cancer diagnostic assay.

    Directory of Open Access Journals (Sweden)

    Hansook Kim Chong

    Full Text Available Breast cancer is the most commonly diagnosed cancer in women, with 10% of disease attributed to hereditary factors. Although BRCA1 and BRCA2 account for a high percentage of hereditary cases, there are more than 25 susceptibility genes that differentially impact the risk for breast cancer. Traditionally, germline testing for breast cancer was performed by Sanger dideoxy terminator sequencing in a reflexive manner, beginning with BRCA1 and BRCA2. The introduction of next-generation sequencing (NGS has enabled the simultaneous testing of all genes implicated in breast cancer resulting in diagnostic labs offering large, comprehensive gene panels. However, some physicians prefer to only test for those genes in which established surveillance and treatment protocol exists. The NGS based BRCAplus test utilizes a custom tiled PCR based target enrichment design and bioinformatics pipeline coupled with array comparative genomic hybridization (aCGH to identify mutations in the six high-risk genes: BRCA1, BRCA2, PTEN, TP53, CDH1, and STK11. Validation of the assay with 250 previously characterized samples resulted in 100% detection of 3,025 known variants and analytical specificity of 99.99%. Analysis of the clinical performance of the first 3,000 BRCAplus samples referred for testing revealed an average coverage greater than 9,000X per target base pair resulting in excellent specificity and the sensitivity to detect low level mosaicism and allele-drop out. The unique design of the assay enabled the detection of pathogenic mutations missed by previous testing. With the abundance of NGS diagnostic tests being released, it is essential that clinicians understand the advantages and limitations of different test designs.

  19. Comprehensive human transcription factor binding site map for combinatory binding motifs discovery.

    Directory of Open Access Journals (Sweden)

    Arnoldo J Müller-Molina

    Full Text Available To know the map between transcription factors (TFs and their binding sites is essential to reverse engineer the regulation process. Only about 10%-20% of the transcription factor binding motifs (TFBMs have been reported. This lack of data hinders understanding gene regulation. To address this drawback, we propose a computational method that exploits never used TF properties to discover the missing TFBMs and their sites in all human gene promoters. The method starts by predicting a dictionary of regulatory "DNA words." From this dictionary, it distills 4098 novel predictions. To disclose the crosstalk between motifs, an additional algorithm extracts TF combinatorial binding patterns creating a collection of TF regulatory syntactic rules. Using these rules, we narrowed down a list of 504 novel motifs that appear frequently in syntax patterns. We tested the predictions against 509 known motifs confirming that our system can reliably predict ab initio motifs with an accuracy of 81%-far higher than previous approaches. We found that on average, 90% of the discovered combinatorial binding patterns target at least 10 genes, suggesting that to control in an independent manner smaller gene sets, supplementary regulatory mechanisms are required. Additionally, we discovered that the new TFBMs and their combinatorial patterns convey biological meaning, targeting TFs and genes related to developmental functions. Thus, among all the possible available targets in the genome, the TFs tend to regulate other TFs and genes involved in developmental functions. We provide a comprehensive resource for regulation analysis that includes a dictionary of "DNA words," newly predicted motifs and their corresponding combinatorial patterns. Combinatorial patterns are a useful filter to discover TFBMs that play a major role in orchestrating other factors and thus, are likely to lock/unlock cellular functional clusters.

    Reading comprehension depends on neural processes supporting the access, understanding, and storage of words over time. Examinations of the neural activity correlated with reading have contributed to our understanding of reading comprehension, especially for the comprehension of sentences and short passages. However, the neural activity associated with comprehending an extended text is not well-understood. Here we describe a current-source-density (CSD) index that predicts individual differences in the comprehension of an extended text. The index is the difference in CSD-transformed event-related potentials (ERPs) to a target word between two conditions: a comprehension condition with words from a story presented in their original order, and a scrambled condition with the same words presented in a randomized order. In both conditions participants responded to the target word, and in the comprehension condition they also tried to follow the story in preparation for a comprehension test. We reasoned that the spatiotemporal pattern of difference-CSDs would reflect comprehension-related processes beyond word-level processing. We used a pattern-classification method to identify the component of the difference-CSDs that accurately (88%) discriminated good from poor comprehenders. The critical CSD index was focused at a frontal-midline scalp site, occurred 400-500 ms after target-word onset, and was strongly correlated with comprehension performance. Behavioral data indicated that group differences in effort or motor preparation could not explain these results. Further, our CSD index appears to be distinct from the well-known P300 and N400 components, and CSD transformation seems to be crucial for distinguishing good from poor comprehenders using our experimental paradigm. Once our CSD index is fully characterized, this neural signature of individual differences in extended-text comprehension may aid the diagnosis and remediation of reading comprehension deficits.

  3. Comprehension and computation in Bayesian problem solving

    Eric D. Johnson

    2015-07-01

    Full Text Available Humans have long been characterized as poor probabilistic reasoners when presented with explicit numerical information. Bayesian word problems provide a well-known example of this, where even highly educated and cognitively skilled individuals fail to adhere to mathematical norms. It is widely agreed that natural frequencies can facilitate Bayesian reasoning relative to normalized formats (e.g. probabilities, percentages, both by clarifying logical set-subset relations and by simplifying numerical calculations. Nevertheless, between-study performance on transparent Bayesian problems varies widely, and generally remains rather unimpressive. We suggest there has been an over-focus on this representational facilitator (i.e. transparent problem structures at the expense of the specific logical and numerical processing requirements and the corresponding individual abilities and skills necessary for providing Bayesian-like output given specific verbal and numerical input. We further suggest that understanding this task-individual pair could benefit from considerations from the literature on mathematical cognition, which emphasizes text comprehension and problem solving, along with contributions of online executive working memory, metacognitive regulation, and relevant stored knowledge and skills. We conclude by offering avenues for future research aimed at identifying the stages in problem solving at which correct versus incorrect reasoners depart, and how individual difference might influence this time point.

    2014-01-01

    Significance: Keratinocytes, a major cellular component of the epidermis, are responsible for restoring the epidermis after injury through a process termed epithelialization. This review will focus on the pivotal role of keratinocytes in epithelialization, including cellular processes and mechanisms of their regulation during re-epithelialization, and their cross talk with other cell types participating in wound healing. Recent Advances: Discoveries in epidermal stem cells, keratinocyte immune function, and the role of the epidermis as an independent neuroendocrine organ will be reviewed. Novel mechanisms of gene expression regulation important for re-epithelialization, including microRNAs and histone modifications, will also be discussed. Critical Issues: Epithelialization is an essential component of wound healing used as a defining parameter of a successful wound closure. A wound cannot be considered healed in the absence of re-epithelialization. The epithelialization process is impaired in all types of chronic wounds. Future Directions: A comprehensive understanding of the epithelialization process will ultimately lead to the development of novel therapeutic approaches to promote wound closure. PMID:25032064

    Human locomotion is a fundamental class of events, and manners of locomotion (e.g., how the limbs are used to achieve a change of location) are commonly encoded in language and gesture. To our knowledge, there is no openly accessible database containing normed human locomotion stimuli. Therefore, we introduce the GestuRe and ACtion Exemplar (GRACE) video database, which contains 676 videos of actors performing novel manners of human locomotion (i.e., moving from one location to another in an unusual manner) and videos of a female actor producing iconic gestures that represent these actions. The usefulness of the database was demonstrated across four norming experiments. First, our database contains clear matches and mismatches between iconic gesture videos and action videos. Second, the male actors and female actors whose action videos matched the gestures in the best possible way, perform the same actions in very similar manners and different actions in highly distinct manners. Third, all the actions in the database are distinct from each other. Fourth, adult native English speakers were unable to describe the 26 different actions concisely, indicating that the actions are unusual. This normed stimuli set is useful for experimental psychologists working in the language, gesture, visual perception, categorization, memory, and other related domains.

    Atrial fibrillation (AF) is the most common type of arrhythmia in humans, yet the genetic cause of AF remains elusive. Genome-wide association studies (GWASs) have reported risk variants in four distinct genetic loci, and more recently, a meta-GWAS has further implicated six new loci in AF. However, the functional role of these AF GWAS-related genes in AF and their inter-relationship remain elusive. To get further insights into the molecular mechanisms driven by Pitx2, calcium handling and novel AF GWAS-associated gene expression were analysed in two distinct Pitx2 loss-of-function models with distinct basal electrophysiological defects; a novel Pitx2 conditional mouse line, Sox2CrePitx2, and our previously reported atrial-specific NppaCrePitx2 line. Molecular analyses of the left atrial appendage in NppaCrePitx2(+/-) and NppaCrePitx2(-/-) adult mice demonstrate that AF GWAS-associated genes such as Zfhx3, Kcnn3, and Wnt8a are severely impaired but not Cav1, Synpo2l, nor Prrx1. In addition, multiple calcium-handling genes such as Atp2a2, Casq2, and Plb are severely altered in atrial-specific NppaCrePitx2 mice in a dose-dependent manner. Functional assessment of calcium homeostasis further underscores these findings. In addition, multiple AF-related microRNAs are also impaired. In vitro over-expression of Wnt8, but not Zfhx3, impairs calcium handling and modulates microRNA expression signature identified in Pitx2 loss-of-function models. Our data demonstrate a dose-dependent relation between Pitx2 expression and the expression of AF susceptibility genes, calcium handling, and microRNAs and identify a complex regulatory network orchestrated by Pitx2 with large impact on atrial arrhythmogenesis susceptibility.

    The omega-3 fatty acid eicosapentaenoic acid (EPA) reduces oxidation of ApoB-containing particles in vitro and in patients with hypertriglyceridemia. EPA may produce these effects through a potent antioxidant mechanism, which may facilitate LDL clearance and slow plaque progression. We hypothesize that EPA antioxidant effects may extend to ApoA-containing particles like HDL, potentially preserving certain atheroprotective functions. HDL was isolated from human plasma and incubated at 37 °C in the absence (vehicle) or presence of EPA and/or DHA; 5.0 or 10.0 μM each. Samples were then subjected to copper-induced oxidation (10 μM). HDL oxidation was inhibited similarly by EPA and DHA up to 1 h. EPA (10 μM) maintained significant HDL oxidation inhibition of 89% (0.622 ± 0.066 μM MDA; p < .001) at 4 h, with continued inhibition of 64% at 14 h, vs. vehicle (5.65 ± 0.06 to 2.01 ± 0.10 μM MDA; p < .001). Conversely, DHA (10 μM) antioxidant benefit was lost by 4 h. At a lower concentration (5 μM), EPA antioxidant activity remained at 81% (5.53 ± 0.15 to 1.03 ± 0.10 μM MDA; p < .001) at 6 h, while DHA lost all antioxidant activity by 4 h. The antioxidant activity of EPA was preserved when combined with an equimolar concentration of DHA (5 μM each). EPA pretreatment prevented HDL oxidation in a dose-dependent manner that was preserved over time. These results suggest unique lipophilic and electron stabilization properties for EPA as compared to DHA with respect to inhibition of HDL oxidation. These antioxidant effects of EPA may enhance certain atheroprotective functions for HDL. Copyright © 2018 The Authors. Published by Elsevier Inc. All rights reserved.

  8. AtHO1 is involved in iron homeostasis in an NO-dependent manner.

    AtHO1 (HY1) encodes heme oxygenase-1 in Arabidopsis, catalyzing cleavage of heme to biliverdin with the release of iron and carbon monoxide (CO). Our previous study showed that CO as an endogenous component is able to improve plant adaptation to iron deficiency. Here, we performed a genetic study to identify further the putative role of AtHO1 in the iron deficiency response. Iron deficiency induced AtHO1 expression at the transcriptional and translational levels. Evidence has been provided that overexpression of AtHO1 could confer plant tolerance to iron deficiency by improving expression of AtFIT, AtFRO2 and AtIRT1, the activity of ferric-chelate reductase (FCR) and iron accumulation. In contrast, RNA interference with AtHO1 expression in 35S::AntiHO1 plants and the AtHO1 loss-of-function (hy1 mutant) resulted in adverse phenotypes. In 35S::AtHO1 transgenic lines, a higher level of CO and water-soluble iron, and a lower level of heme were identified, suggesting that AtHO1-regulated iron homeostasis was possibly through the catabolism of heme to produce CO and free iron. Because nitric oxide (NO) is known to regulate iron homeostasis in plants, the connection between AtHO1 expression and NO action was examined. AtHO1-overexpressing plants generated more NO, whereas knock-down of AtHO1 expression reduced the level of NO in plants. The NO scavenger cPTIO [2-(4-carboxy-2-phenyl)-4,4,5,5-tetramethylini dazoline-1-oxyl-3-oxide] caused a decrease in AtHO1-induced FCR activity. Under both iron-sufficient and -deficient conditions, administration of the NO donor sodium nitroprusside induced FCR activity in the hy1 plants. These results suggest that AtHO1 is involved in iron homeostasis in an NO-dependent manner.

    Full Text Available Students who can meet the demands of academic discourse develop cognitive and metacognitive skills with which to understand the information they get from reading scientific texts, and thus establish their learning. In this work, a group of university students were evaluated concerning their competencies and deficiencies in the reading comprehension of a fragment of a scientific text used in one of their courses. The results allowed us to assess the most frequent difficulties in processing information and in understanding what they read. The group was made up of a few students skilled in reading comprehension skills, plus several inexpert readers with little capacity to monitor and assess their own understanding.

  10. Focus, accent, and argument structure: effects on language comprehension.

    1995-01-01

    Four experiments investigated the effect of syntactic argument structure on the evaluation and comprehension of utterances with different patterns of pitch accents. Linguistic analyses of the relation between focus and prosody note that it is possible for certain accented constituents within a broadly focused phrase to project focus to the entire phrase. We manipulated focus requirements and accent in recorded question-answer pairs and asked listeners to make linguistic judgments of prosodic appropriateness (Experiments 1 and 3) or to make judgments based on meaningful comprehension (Experiments 2 and 4). Naive judgments of prosodic appropriateness were generally consistent with the linguistic analyses, showing preferences for utterances in which contextually new noun phrases received accent and old noun phrases did not, but suggested that an accented new argument NP was not fully effective in projecting broad focus to the entire VP. However, the comprehension experiments did demonstrate that comprehension of a sentence with broad VP focus was as efficient when only a lexical argument NP received accent as when both NP and verb received accent. Such focus projection did not occur when the argument NP was an "independent quantifier" such as nobody or everything. The results extend existing demonstrations that the ease of understanding spoken discourse depends on appropriate intonational marking of focus to cases where certain structurally-defined words can project focus-marking to an entire phrase.

  11. Understanding quantum physics

    Spillner, Vera

    2011-01-01

    This thesis presents a bundle definition for 'scientific understanding' through which the empirically equivalent interpretations of quantum mechanics can be evaluated with respect to the understanding they generate. The definition of understanding is based on a sufficient and necessary criterion, as well as a bundle of conditions - where a theory can be called most understandable whenever it fulfills the highest number of bundle criteria. Thereby the definition of understanding is based on the one hand on the objective number of criteria a theory fulfills, as well as, on the other hand, on the individual's preference of bundle criteria. Applying the definition onto three interpretations of quantum mechanics, the interpretation of David Bohm appears as most understandable, followed by the interpretation of Tim Maudlin and the Kopenhagen interpretation. These three interpretations are discussed in length in my thesis. (orig.)

  12. Cardiac myosin binding protein C phosphorylation affects cross-bridge cycle's elementary steps in a site-specific manner.

    Full Text Available Based on our recent finding that cardiac myosin binding protein C (cMyBP-C phosphorylation affects muscle contractility in a site-specific manner, we further studied the force per cross-bridge and the kinetic constants of the elementary steps in the six-state cross-bridge model in cMyBP-C mutated transgenic mice for better understanding of the influence of cMyBP-C phosphorylation on contractile functions. Papillary muscle fibres were dissected from cMyBP-C mutated mice of ADA (Ala273-Asp282-Ala302, DAD (Asp273-Ala282-Asp302, SAS (Ser273-Ala282-Ser302, and t/t (cMyBP-C null genotypes, and the results were compared to transgenic mice expressing wide-type (WT cMyBP-C. Sinusoidal analyses were performed with serial concentrations of ATP, phosphate (Pi, and ADP. Both t/t and DAD mutants significantly reduced active tension, force per cross-bridge, apparent rate constant (2πc, and the rate constant of cross-bridge detachment. In contrast to the weakened ATP binding and enhanced Pi and ADP release steps in t/t mice, DAD mice showed a decreased ADP release without affecting the ATP binding and the Pi release. ADA showed decreased ADP release, and slightly increased ATP binding and cross-bridge detachment steps, whereas SAS diminished the ATP binding step and accelerated the ADP release step. t/t has the broadest effects with changes in most elementary steps of the cross-bridge cycle, DAD mimics t/t to a large extent, and ADA and SAS predominantly affect the nucleotide binding steps. We conclude that the reduced tension production in DAD and t/t is the result of reduced force per cross-bridge, instead of the less number of strongly attached cross-bridges. We further conclude that cMyBP-C is an allosteric activator of myosin to increase cross-bridge force, and its phosphorylation status modulates the force, which is regulated by variety of protein kinases.

    Is there a relationship between decidualization and apoptosis of decidual stromal cells (DSC)? Decidualization triggers the secretion of soluble factors that induce apoptosis in DSC. The differentiation and apoptosis of DSC during decidualization of the receptive decidua are crucial processes for the controlled invasion of trophoblasts in normal pregnancy. Most DSC regress in a time-dependent manner, and their removal is important to provide space for the embryo to grow. However, the mechanism that controls DSC death is poorly understood. The apoptotic response of DSC was analyzed after exposure to different exogenous agents and during decidualization. The apoptotic potential of decidualized DSC supernatants and prolactin (PRL) was also evaluated. DSC lines were established from samples of decidua from first trimester pregnancies. Apoptosis was assayed by flow cytometry. PRL production, as a marker of decidualization, was determined by enzyme-linked immunosorbent assay. DSCs were resistant to a variety of apoptosis-inducing substances. Nevertheless, DSC underwent apoptosis during decidualization in culture, with cAMP being essential for both apoptosis and differentiation. In addition, culture supernatants from decidualized DSC induced apoptosis in undifferentiated DSC, although paradoxically these supernatants decreased the spontaneous apoptosis of decidual lymphocytes. Exogenously added PRL did not induce apoptosis in DSC and an antibody that neutralized the PRL receptor did not decrease the apoptosis induced by supernatants. Further studies are needed to examine the involvement of other soluble factors secreted by decidualized DSC in the induction of apoptosis. The present results indicate that apoptosis of DSC occurs in parallel to differentiation, in response to decidualization signals, with soluble factors secreted by decidualized DSC being responsible for triggering cell death. These studies are relevant in the understanding of how the regression of decidua

  14. Electrical Microstimulation of the Pulvinar Biases Saccade Choices and Reaction Times in a Time-Dependent Manner

    Science.gov (United States)

    2017-01-01

    The pulvinar complex is interconnected extensively with brain regions involved in spatial processing and eye movement control. Recent inactivation studies have shown that the dorsal pulvinar (dPul) plays a role in saccade target selection; however, it remains unknown whether it exerts effects on visual processing or at planning/execution stages. We used electrical microstimulation of the dPul while monkeys performed saccade tasks toward instructed and freely chosen targets. Timing of stimulation was varied, starting before, at, or after onset of target(s). Stimulation affected saccade properties and target selection in a time-dependent manner. Stimulation starting before but overlapping with target onset shortened saccadic reaction times (RTs) for ipsiversive (to the stimulation site) target locations, whereas stimulation starting at and after target onset caused systematic delays for both ipsiversive and contraversive locations. Similarly, stimulation starting before the onset of bilateral targets increased ipsiversive target choices, whereas stimulation after target onset increased contraversive choices. Properties of dPul neurons and stimulation effects were consistent with an overall contraversive drive, with varying outcomes contingent upon behavioral demands. RT and choice effects were largely congruent in the visually-guided task, but stimulation during memory-guided saccades, while influencing RTs and errors, did not affect choice behavior. Together, these results show that the dPul plays a primary role in action planning as opposed to visual processing, that it exerts its strongest influence on spatial choices when decision and action are temporally close, and that this choice effect can be dissociated from motor effects on saccade initiation and execution. SIGNIFICANCE STATEMENT Despite a recent surge of interest, the core function of the pulvinar, the largest thalamic complex in primates, remains elusive. This understanding is crucial given the central

  15. Relationship between Prior Knowledge and Reading Comprehension

    2014-12-01

    Full Text Available This study investigates the relationship between prior knowledge and reading comprehension in second language among postgraduate students in UPM. Participants in the study were 20 students who have the same level in English as a second language from several faculties. On the basis of a prior-knowledge questionnaire and test, students were selected; they were asked to sit a two-passage reading comprehension exam. According to the questionnaire and the short prior quiz, students had high prior knowledge in one of the two passages, and low prior knowledge in the other. The result showed significantly high relationship between the high prior knowledge and reading comprehension. However, the results showed significantly low relationship between low prior knowledge and reading comprehension. Yet the performance of students in a reading comprehension with high prior knowledge was significantly better than reading comprehension with low prior knowledge.

    Comprehension emerges as the results of inference and strategic processes that support the construction of a coherent mental model for a text. However, the vast majority of comprehension skills tests adopt a format that does not afford an assessment of these processes as they operate during reading. This study assessed the viability of the Reading Strategy Assessment Tool (RSAT), which is an automated computer-based reading assessment designed to measure readers' comprehension and spontaneous use of reading strategies while reading texts. In the tool, readers comprehend passages one sentence at a time, and are asked either an indirect ("What are your thoughts regarding your understanding of the sentence in the context of the passage?") or direct (e.g., why X?) question after reading each pre-selected target sentence. The answers to the indirect questions are analyzed on the extent that they contain words associated with comprehension processes. The answers to direct questions are coded for the number of content words in common with an ideal answer, which is intended to be an assessment of emerging comprehension. In the study, the RSAT approach was shown to predict measures of comprehension comparable to standardized tests. The RSAT variables were also shown to correlate with human ratings. The results of this study constitute a "proof of concept" and demonstrate that it is possible to develop a comprehension skills assessment tool that assesses both comprehension and comprehension strategies.

  18. CEDR: Comprehensive Epidemiologic Data Resource

    Energy Technology Data Exchange (ETDEWEB)

    1993-08-01

    The Department of Energy (DOE) and its predecessor agencies have a long history of epidemiologic research programs. The main focus of these programs has been the Health and Mortality Study of the DOE work force. This epidemiologic study began in 1964 with a feasibility study of workers at the Hanford facility. Studies of other populations exposed to radiation have also been supported, including the classic epidemiologic study of radium dial painters and studies of atomic bomb survivors. From a scientific perspective, these epidemiologic research program have been productive, highly credible, and formed the bases for many radiological protection standards. Recently, there has been concern that, although research results were available, the data on which these results were based were not easily obtained by interested investigators outside DOE. Therefore, as part of an effort to integrate and broaden access to its epidemiologic information, the DOE has developed the Comprehensive Epidemiologic Data Resource (CEDR) Program. Included in this effort is the development of a computer information system for accessing the collection of CEDR data and its related descriptive information. The epidemiologic data currently available through the CEDAR Program consist of analytic data sets, working data sets, and their associated documentation files. In general, data sets are the result of epidemiologic studies that have been conducted on various groups of workers at different DOE facilities during the past 30 years.

    Full Text Available Intraperitoneal spread may occur with gynecological epithelial neoplasms, as well as with non-gynecological malignancies, which may result in serosal involvement with or without concomitant effusion. Therefore, washings in patients with abdominopelvic tumors represent important specimens for cytologic examination. They are primarily utilized for staging ovarian cancers, although their role has decreased in staging of endometrial and cervical carcinoma. Abdominopelvic washings can be positive in a variety of pathologic conditions, including benign conditions, borderline neoplastic tumors, locally invasive tumors, or distant metastases. In a subset of cases, washings can be diagnostically challenging due to the presence of co-existing benign cells (e.g., mesothelial hyperplasia, endosalpingiosis, or endometriosis, lesions in which there is only minimal atypia (e.g., serous borderline tumors or scant atypical cells, and the rarity of specific tumor types (e.g., mesothelioma. Ancillary studies including immunocytochemistry and fluorescence in situ hybridization may be required in difficult cases to resolve the diagnosis. This article provides a comprehensive and contemporary review of abdominopelvic washings in the evaluation of gynecologic and non-gynecologic tumors, including primary peritoneal and mesothelial entities.

    The present article is aimed on comprehensive view of Swine flu. It was first isolated from pigs in 1930 in USA. Pandemic caused by H1N1 in 2009 brought it in limelight. Itís a viral respiratory disease caused by viruses that infects pigs, resulting in nasal secretions, barking cough, decreased appetite, and listless behavior. Swine virus consist of eight RNA strands, one strand derived from human flu strains, two from avian (bird) strains, and five from swine strains. Swine flu spreads from infected person to healthy person by inhalation or ingestion of droplets contaminated with virus while sneezing or coughing. Two antiviral agents have been reported to help prevent or reduce the effects of swine flu, flu shot and nasal spray. WHO recommended for pandemic period to prevent its future outbreaks through vaccines or non-vaccines means. Antiviral drugs effective against this virus are Tamiflu and Relenza. Rapid antigen testing (RIDT), DFA testing, viral culture, and molecular testing (RT-PCR) are used for its diagnosis in laboratory

    2014-09-01

    Full Text Available Diabetic nephropathy (DN is a leading cause of mortality and morbidity in patients with diabetes. This complication reflects a complex pathophysiology, whereby various genetic and environmental factors determine susceptibility and progression to end-stage renal disease. DN should be considered in patients with type 1 diabetes for at least 10 years who have microalbuminuria and diabetic retinopathy, as well as in patients with type 1 or type 2 diabetes with macroalbuminuria in whom other causes for proteinuria are absent. DN may also present as a falling estimated glomerular filtration rate with albuminuria as a minor presenting feature, especially in patients taking renin–angiotensin–aldosterone system inhibitors (RAASi. The pathological characteristic features of disease are three major lesions: diffuse mesangial expansion, diffuse thickened glomerular basement membrane, and hyalinosis of arterioles. Functionally, however, the pathophysiology is reflected in dysfunction of the mesangium, the glomerular capillary wall, the tubulointerstitium, and the vasculature. For all diabetic patients, a comprehensive approach to management including glycemic and hypertensive control with RAASi combined with lipid control, dietary salt restriction, lowering of protein intake, increased physical activity, weight reduction, and smoking cessation can reduce the rate of progression of nephropathy and minimize the risk for cardiovascular events. This review focuses on the latest published data dealing with the mechanisms, diagnosis, and current treatment of DN.

    2015-10-01

    Rosacea is a common chronic inflammatory dermatosis of unclear origin. It has been associated with systemic comorbidities, but methodical studies addressing this association are lacking. We evaluated: (1) the association between rosacea and systemic comorbidities; and (2) if the severity of rosacea is impacted by comorbidities. This was a case-control study: patients with rosacea were matched (1:1) to rosacea-free control subjects by age, sex, and race. Relative risk estimates were calculated using logistic regression as odds ratios with 95% confidence intervals. Among 130 participants (65 patients/65 control subjects), we observed a significant association between rosacea and allergies (airborne, food), respiratory diseases, gastroesophageal reflux disease, other gastrointestinal diseases, hypertension, metabolic and urogenital diseases, and female hormone imbalance. Compared with mild rosacea, moderate to severe rosacea was significantly associated with hyperlipidemia, hypertension, metabolic diseases, cardiovascular diseases, and gastroesophageal reflux disease. This was a case-control study with moderate sample size. Associated medical conditions were self-reported and could not always be confirmed by medication use and medical records. Rosacea is associated with numerous systemic comorbid diseases in a skin severity-dependent manner. Physicians should be aware of these associations to provide comprehensive care to patients with rosacea, especially to those with more severe disease.

    2017-04-20

    In this article, we respond to Catts and Kamhi's (2017) argument that reading comprehension is not a single ability. We provide a brief review of the impact of strategy instruction, the importance of knowledge in reading comprehension, and possible avenues for future research and practice. We agree with Catts and Kamhi's argument that reading comprehension is a complex endeavor and that current recommended practices do not reflect the complexity of the construct. Knowledge building, despite its important role in comprehension, has been relegated to a back seat in reading comprehension instruction. In the final section of the article, we outline possible avenues for research and practice (e.g., generative language instruction, dialogic approaches to knowledge building, analogical reasoning and disciplinary literacy, the use of graphics and media, inference instruction) for improving reading-comprehension outcomes. Reading comprehension is a complex ability, and comprehension instruction should reflect this complexity. If we want to have an impact on long-term growth in reading comprehension, we will need to expand our current repertoire of instructional methods to include approaches that support the acquisition and integration of knowledge across a variety of texts and topics.

    Full Text Available The current approach to reading comprehension instruction is not producing the desired outcomes. Provincial, national and international tests indicate that more than half of South African learners cannot read, understand and answer basic comprehension questions. This research project was informed by Vygotsky’s socio-cultural theory. A case study was conducted with a ten-year old Grade 4 boy who experienced difficulty with understanding comprehension questions. A six-week intervention was designed to improve his comprehension abilities and to identify instructional principles that were appropriate for him. Interviews and observations were conducted and inductively analysed. Findings showed that the learner was well equipped to retrieve explicitly stated information but struggled with higher-order level questions such as drawing inferences or evaluating content. Certain instructional practices were more favourable than others when teaching reading strategies.

    2015-12-01

    Full Text Available The study identified how Saudi schoolteachers perceive reading and comprehension. It also investigated the effect of teachers’ willingness and lesson presentation on learners’ achievement. A descriptive approach was used, and the sample consisted of 56 teachers. The lesson plan in Broughton et al.’s study was adopted as a model lesson plan. Respondents’ responses revealed their poor awareness of the most important activities that facilitate or hinder comprehension. Furthermore, teachers’ willingness and readiness to teach reading were not sufficient to yield competent teachers. It concluded that students were not given sufficient time and assigned to cleverly chosen roles to better understand the text. Teachers, however, should reconsider their daily lesson plans through which reading lessons are executed, taking into account students’ culture, interests, feelings, and so forth. Finally, other researchers were recommended to investigate the differences in students’ achievement levels due to the adoption of the lesson plan proposed by Broughton et al.

  16. Sweet silent thought: alliteration and resonance in poetry comprehension.

    Lea, R Brooke; Rapp, David N; Elfenbein, Andrew; Mitchel, Aaron D; Romine, Russell Swinburne

    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.

    2008-01-01

    Full Text Available The article contributes to the discussion of the premises and practical consequences of social constructionism in of the context of psychotherapeutic practice. The article is based on the presupposition that the use of metaphors is an important aspect of therapeutic interaction and that they contribute to transformation not only within the therapeutic dialogue. For these ends a few metaphors implying processes of social construction are presented—some gaining their effect of clarification through intended alienation. These processes are exemplified further in the psychotherapeutic context by presenting diagnoses as relational constructions. We end with a brief case study that highlights the social constructionist understanding of therapeutic dialogues. URN: urn:nbn:de:0114-fqs0801455

    Obesity is a multifactorial, chronic disease that has proven difficult to treat. An increased understanding of aetiological mechanisms is critical to the development of more effective obesity prevention and treatment strategies. A growing body of empirical evidence has demonstrated parallels between obesity, overeating and substance abuse, including shared behavioural, psychological and neurophysiological factors implicated in the excessive intake of both food and substances of abuse. Several different lines of research have recently emerged that hold the potential to shed light on the connection between obesity, food reward and addiction, with studies examining changes in alcohol use/misuse after weight loss surgery providing a particularly interesting perspective on these interrelationships. However, these lines of investigation have proceeded in relative isolation, and relevant research findings have yet to be integrated in a synthesized, comprehensive manner. To provide an opportunity to achieve such a synthesis, a scientific symposium was convened at the Radcliffe Institute in Cambridge, Massachusetts. Invited participants were researchers working in diverse domains related to the intersection between obesity and addiction. Extensive discussion was generated suggesting novel research directions. In this article, we summarize and synthesize the symposium participants' ongoing research in this area, incorporating additional relevant research holding potential clues regarding the connections between obesity, weight loss surgery and addiction. © 2017 World Obesity Federation.

  19. Legionella Effector AnkX Disrupts Host Cell Endocytic Recycling in a Phosphocholination-Dependent Manner

    Directory of Open Access Journals (Sweden)

    Samual C. Allgood

    2017-09-01

    Full Text Available The facultative intracellular bacterium Legionella pneumophila proliferates within amoebae and human alveolar macrophages, and it is the causative agent of Legionnaires' disease, a life-threatening pneumonia. Within host cells, L. pneumophila establishes a replicative haven by delivering numerous effector proteins into the host cytosol, many of which target membrane trafficking by manipulating the function of Rab GTPases. The Legionella effector AnkX is a phosphocholine transferase that covalently modifies host Rab1 and Rab35. However, a detailed understanding of the biological consequence of Rab GTPase phosphocholination remains elusive. Here, we broaden the understanding of AnkX function by presenting three lines of evidence that it interferes with host endocytic recycling. First, using immunogold transmission electron microscopy, we determined that GFP-tagged AnkX ectopically produced in mammalian cells localizes at the plasma membrane and tubular membrane compartments, sites consistent with targeting the endocytic recycling pathway. Furthermore, the C-terminal region of AnkX was responsible for association with the plasma membrane, and we determined that this region was also able to bind the phosphoinositide lipids PI(3P and PI(4P in vitro. Second, we observed that mCherry-AnkX co-localized with Rab35, a regulator of recycling endocytosis and with major histocompatibility class I protein (MHC-I, a key immunoregulatory protein whose recycling from and back to the plasma membrane is Rab35-dependent. Third, we report that during infection of macrophages, AnkX is responsible for the disruption of endocytic recycling of transferrin, and AnkX's phosphocholination activity is critical for this function. These results support the hypothesis that AnkX targets endocytic recycling during host cell infection. Finally, we have demonstrated that the phosphocholination activity of AnkX is also critical for inhibiting fusion of the Legionella

    This chapter serves to introduce the geophysics of Neotropical steeplands. Topics are covered in a general manner with hyperlinks to active research and monitoring sites (such as the National Hurricane Center and US Geological Survey publication). Topics covered include ‘tropical climate and weather,’ ‘climate variations and trends,’ Neotropical ‘geology, and soils,’ ‘hillslopes and erosion,’ ‘lakes and reservoirs,’ and ‘effects of land cover on water quality and quantity.’ Obviously, this is a lot of information to cover in a short chapter, hence the use of hyperlinks. The last theme ‘effects of land cover on water quality and quantity’ is covered by case studies, in all of which I have been centrally involved. These studies were chosen because they are among the few studies with sufficient data of high enough quality to reach definitive conclusions.

    McDougald, Brannan R; Wogalter, Michael S

    2014-09-01

    Pictorials can aid in communicating warning information, but viewers may not always correctly comprehend them. Two experiments focused on whether the use of relevant highlighting could benefit pictorial comprehension. A set of warning-related pictorials were manipulated according to three-color highlighting conditions: highlighting areas more relevant to correct comprehension, highlighting areas less relevant to comprehension, and no highlighting. Participants were asked to describe the purpose and meaning of each pictorial presented to them. The findings from both experiments indicate that comprehension of warning pictorials is higher for the relevant highlighting condition than the other two conditions. The highlighting of less relevant areas reduced comprehension compared to no highlighting. Use of appropriately placed highlighting could benefit the design of a complex symbol by pointing out pertinent areas to aid in determining its intended conceptual meaning.

    2016-06-01

    In Turkey, rapid population growth, informal settlements, and buildings and infrastructures vulnerable to natural hazards are seen as the most important problems of cities. Particularly disaster risk cannot be disregarded, as large parts of various cities are facing risks from earthquakes, floods and landslides and have experienced loss of lives in the recent past. Urban regeneration is an important planning tool implemented by local and central governments in order to reduce to disaster risk and to design livable environments for the citizens. The Law on the Regeneration of Areas under Disaster Risk, commonly known as the Urban Regeneration Law, was enacted in 2012 (Law No.6306, May 2012). The regulation on Implementation of Law No. 6306 explains the fundamental steps of the urban regeneration process. The relevant institutions furnished with various authorities such as expropriation, confiscation and changing the type and place of your property which makes urban regeneration projects very important in terms of property rights. Therefore, urban regeneration projects have to be transparent, comprehensible and acceptable for all actors in the projects. In order to understand the urban regeneration process, the legislation and projects of different municipalities in Istanbul have been analyzed. While some steps of it are spatial data demanding, others relate to land values. In this paper an overview of the urban regeneration history and activities in Turkey is given. Fundamental steps of the urban regeneration process are defined, and particularly spatial-data demanding steps are identified.

  9. Hypoxia favors myosin heavy chain beta gene expression in an Hif-1alpha-dependent manner.

    The potentiation of the naturally limited regenerative capacity of the heart is dependent on an understanding of the mechanisms that are activated in response to pathological conditions such as hypoxia. Under these conditions, the expression of genes suggested to support cardiomyocyte survival and heart adaptation is triggered. Particularly important are changes in the expression of myosin heavy chain (MHC) isoforms. We propose here that alterations in the expression profiles of MHC genes are induced in response to hypoxia and are primarily mediated by hypoxia inducible factor (HIF). In in vitro models of mouse embryonic stem cell-derived cardiomyocytes, we showed that hypoxia (1% O 2 ) or the pharmacological stabilization of HIFs significantly increased MHCbeta ( Myh7 ) gene expression. The key role of HIF-1alpha is supported by the absence of these effects in HIF-1alpha-deficient cells, even in the presence of HIF-2alpha. Interestingly, ChIP analysis did not confirm the direct interaction of HIF-1alpha with putative HIF response elements predicted in the MHCalpha and beta encoding DNA region. Further analyses showed the significant effect of the mTOR signaling inhibitor rapamycin in inducing Myh7 expression and a hypoxia-triggered reduction in the levels of antisense RNA transcripts associated with the Myh7 gene locus. Overall, the recognized and important role of HIF in the regulation of heart regenerative processes could be highly significant for the development of novel therapeutic interventions in heart failure.

  10. Autophagy modulates dynamics of connexins at the plasma membrane in a ubiquitin-dependent manner

    Different pathways contribute to the turnover of connexins, the main structural components of gap junctions (GJs). The cellular pool of connexins targeted to each pathway and the functional consequences of degradation through these degradative pathways are unknown. In this work, we focused on the contribution of macroautophagy to connexin degradation. Using pharmacological and genetic blockage of macroautophagy both in vitro and in vivo, we found that the cellular pool targeted by this autophagic system is primarily the one organized into GJs. Interruption of connexins' macroautophagy resulted in their retention at the plasma membrane in the form of functional GJs and subsequent increased GJ-mediated intercellular diffusion. Up-regulation of macroautophagy alone is not sufficient to induce connexin internalization and degradation. To better understand what factors determine the autophagic degradation of GJ connexins, we analyzed the changes undergone by the fraction of plasma membrane connexin 43 targeted for macroautophagy and the sequence of events that trigger this process. We found that Nedd4-mediated ubiquitinylation of the connexin molecule is required to recruit the adaptor protein Eps15 to the GJ and to initiate the autophagy-dependent internalization and degradation of connexin 43. This study reveals a novel regulatory role for macroautophagy in GJ function that is directly dependent on the ubiquitinylation of plasma membrane connexins. PMID:22496425

    Full Text Available Piotr Chmielowski, one of the most important literary critics and historians of the literature of the Positivist period, had an enormous role in shaping the opinion on the literary output of Aleksander Michaux (pen-name Miron. The critic contributed much to strengthen the negative image of the poet by discrediting his works using unfounded and groundless accusations of their non-original character, or by a selective choice of citations aimed to ridicule the author, among others. The accusations forwarded by Chmielowski, mainly those referring to the alleged anachronism or even Miron’s dislike of progress, were simplyichaux reflected well the universal resentment of Positivist critics towards contemporary poets and testified to a particular understanding of the goals of lyric poetry and the principles governing it. Any literary output that did not fulfill the requirements of utilitarianism was supposed to be shunned and removed beyond the mainstream of the Polish literature of the time. The conviction on low artistic merit of the poetic output of the Positivist period, formed as early as the latter half of the nineteenth century, has lingered among a sizeable number of modern readers of literature.

  12. Chronic cadmium exposure stimulates SDF-1 expression in an ERα dependent manner.

    Directory of Open Access Journals (Sweden)

    Esmeralda Ponce

    Full Text Available Cadmium is an omnipotent environmental contaminant associated with the development of breast cancer. Studies suggest that cadmium functions as an endocrine disruptor, mimicking the actions of estrogen in breast cancer cells and activating the receptor to promote cell growth. Although acute cadmium exposure is known to promote estrogen receptor-mediated gene expression associated with growth, the consequence of chronic cadmium exposure is unclear. Since heavy metals are known to bioaccumulate, it is necessary to understand the effects of prolonged cadmium exposure. This study aims to investigate the effects of chronic cadmium exposure on breast cancer progression. A MCF7 breast cancer cell line chronically exposed to 10(-7 M CdCl2 serves as our model system. Data suggest that prolonged cadmium exposures result in the development of more aggressive cancer phenotypes - increased cell growth, migration and invasion. The results from this study show for the first time that chronic cadmium exposure stimulates the expression of SDF-1 by altering the molecular interactions between ERα, c-jun and c-fos. This study provides a mechanistic link between chronic cadmium exposure and ERα and demonstrates that prolonged, low-level cadmium exposure contributes to breast cancer progression.

Since effects and mechanisms seem to be dose and time-dependent, flatfish are an interesting study model as they undergo a characteristic process of metamorphosis driven by THs that can be followed by external appearance. Here, we studied the effects of VA imbalance that might determine Senegalese sole (Solea senegalensis skeletogenetic phenotype through development of thyroid follicles, THs homeostasis and signaling when a dietary VA excess was specifically provided during pre-, pro- or post-metamorphic stages using enriched rotifers and Artemia as carriers. The increased VA content in enriched live prey was associated to a higher VA content in fish at all developmental stages. Dietary VA content clearly affected thyroid follicle development, T3 and T4 immunoreactive staining, skeletogenesis and mineralization in a dose and time-dependent fashion. Gene expression analysis showed that VA levels modified the mRNA abundance of VA- and TH-specific nuclear receptors at specific developmental stages. Present results provide new and key knowledge to better understand how VA and TH pathways interact at tissue, cellular and nuclear level at different developmental periods in Senegalese sole, unveiling how dietary modulation might determine juvenile phenotype and physiology.

  14. Overexpression of Drosophila frataxin triggers cell death in an iron-dependent manner.

    Friedreich ataxia (FRDA) is the most important autosomal recessive ataxia in the Caucasian population. FRDA patients display severe neurological and cardiac symptoms that reflect a strong cellular and axonal degeneration. FRDA is caused by a loss of function of the mitochondrial protein frataxin which impairs the biosynthesis of iron-sulfur clusters and in turn the catalytic activity of several enzymes in the Krebs cycle and the respiratory chain leading to a diminished energy production. Although FRDA is due to frataxin depletion, overexpression might also be very helpful to better understand cellular functions of frataxin. In this work, we have increased frataxin expression in neurons to elucidate specific roles that frataxin might play in these tissues. Using molecular, biochemical, histological and behavioral methods, we report that frataxin overexpression is sufficient to increase oxidative phosphorylation, modify mitochondrial morphology, alter iron homeostasis and trigger oxidative stress-dependent cell death. Interestingly, genetic manipulation of mitochondrial iron metabolism by silencing mitoferrin successfully improves cell survival under oxidative-attack conditions, although enhancing antioxidant defenses or mitochondrial fusion failed to ameliorate frataxin overexpression phenotypes. This result suggests that cell degeneration is directly related to enhanced incorporation of iron into the mitochondria. Drosophila frataxin overexpression might also provide an alternative approach to identify processes that are important in FRDA such as changes in mitochondrial morphology and oxidative stress induced cell death.

    Interpreting and creating graphs plays a critical role in scientific practice. The K-12 Next Generation Science Standards call for students to use graphs for scientific modeling, reasoning, and communication. To measure progress on this dimension, we need valid and reliable measures of graph understanding in science. In this research, we designed items to measure graph comprehension, critique, and construction and developed scoring rubrics based on the knowledge integration (KI) framework. We administered the items to over 460 middle school students. We found that the items formed a coherent scale and had good reliability using both item response theory and classical test theory. The KI scoring rubric showed that most students had difficulty linking graphs features to science concepts, especially when asked to critique or construct graphs. In addition, students with limited access to computers as well as those who speak a language other than English at home have less integrated understanding than others. These findings point to the need to increase the integration of graphing into science instruction. The results suggest directions for further research leading to comprehensive assessments of graph understanding.

  17. Emergency management: Does it have a sufficiently comprehensive understanding of decision-making, process and context?

    International Nuclear Information System (INIS)

    Niculae, C.; French, S.; Carter, E.

    2004-01-01

    It is widely recognised in the social and management sciences that the effective support of decision-making requires a multidisciplinary perspective. This trend is also clear in nuclear emergency management (EM). However, communication between disciplines is not easy to maintain in EM contexts when the decision makers (DMs) are likely to be highly stressed. Such circumstances can lead them to revert to the instinctive patterns of perception of their core disciplines, making communication between disciplines difficult and, perhaps, obscuring complex interactions that have not been rehearsed in practice exercises. This paper explores decision making in EM and the nature of the socio-technical issues that will arise, suggesting that despite the lessons of past accidents the research EM community is still not taking a broad enough view of what future incidents may entail.

    2015-01-01

    We report on the analysis of the performance of each electrode of an air-breathing passive micro-direct methanol fuel cell (µDMFC) during polarization, stabilization and discharge, with CH3OH (2-20 M). A reference electrode with a microcapillary was used for separately measuring the anode the cathode potential. Information about the open circuit potential (OCP), the voltage and the mass transport related phenomena are available. Using 2 M CH3OH, the anode showed mass transport problems. With 4 and 6 M CH3OH both electrodes experience this situation, whereas with 10 and 20 M CH3OH the issue is attributed to the cathode. The stabilization and fuel consumption time depends mainly on the cathode performance, which is very sensitive to fuel crossover. The exposure to 20 M CH3OH produced a loss in performance of more than 75% of the highest power density (16.3 mW·cm(-2)).

  5. Comprehensive Understanding of the Zipingpu Reservoir to the Ms8.0 Wenchuan Earthquake

    2014-12-01

    After the Wenchuan earthquake occurred, whether the big earthquake triggered by the storage of the Zipingpu Reservoir has attracted wide attention in international academic community. In addition to the qualitative discussion, many scholars also adopted the quantitative analysis methods to calculate the stress changes, but due to the different results, they draw very different conclusions. Here, we take the dispute of different teams in the quantitative calculation of Zipingpu reservoir as a starting point. In order to find out the key influence factors of quantitative calculation and know about the existing uncertainty elements during the numerical simulation, we analyze factors which may cause the differences. The preliminary results show that the calculation methods (analytical method or numerical method), dimension of models (2-D or 3-D), diffusion model, diffusion coefficient and focal mechanism are the main factors resulted in the differences, especially the diffusion coefficient of the fractured rock mass. The change of coulomb failure stress of the epicenter of Wenchuan earthquake attained from 2-D model is about 3 times of that of 3-D model. And it is not reasonable that only considering the fault permeability (assuming the permeability of rock mass as infinity) or only considering homogeneous isotropic rock mass permeability (ignoring the fault permeability). The different focal mechanisms also could dramatically affect the change of coulomb failure stress of the epicenter of Wenchuan earthquake, and the differences can research 2-7 times. And the differences the change of coulomb failure stress can reach several hundreds times, when selecting different diffusion coefficients. According to existing research that the magnitude of coulomb failure stress change is about several kPa, we could not rule out the possibility that the Zipingpu Reservoir may trigger the 2008 Wenchuan earthquake. However, for the background stress is not clear and coulomb failure stress change is too little, we also not sure there must be a connection between reservoir and earthquake. In future work, we should target on the basis of field survey and indoor experiment, improve the model and develop high performance simulation.

    Because age is the greatest risk factor for sporadic Alzheimer's disease (AD), phenotypic screens based upon old age-associated brain toxicities were used to develop the potent neurotrophic drug J147. Since certain aspects of aging may be primary cause of AD, we hypothesized that J147 would be effective against AD-associated pathology in rapidly aging SAMP8 mice and could be used to identify some of the molecular contributions of aging to AD. An inclusive and integrative multiomics approach was used to investigate protein and gene expression, metabolite levels, and cognition in old and young SAMP8 mice. J147 reduced cognitive deficits in old SAMP8 mice, while restoring multiple molecular markers associated with human AD, vascular pathology, impaired synaptic function, and inflammation to those approaching the young phenotype. The extensive assays used in this study identified a subset of molecular changes associated with aging that may be necessary for the development of AD.

    The femtosecond (FS) laser is a novel laser technology, and is approved clinical application by FDA in 2000. FS laser initially mainly used in corneal refractive surgery to replace the mechanical microkeratome. Since the accuracy and controllability of the FS laser is very high, it shows superiority in the field of corneal refractive surgery. And with the development of the relative hard and software, FS laser is began to used in other fields of ophthalmology, such as corneal transplants, cataract surgery, as well as assisted diagnosis et al., although still have some limitations, the preliminary clinical results have been shown a very good prospects in the ophthalmology fields. Therefore, we reviewed the alternative applications, challenges and limitations, research direction in the future of FS laser, so that provide a reference and revelations for the peers.

  9. Developmental ethanol exposure alters the morphology of mouse prefrontal neurons in a layer-specific manner.

    Chronic developmental exposure to ethanol can lead to a wide variety of teratogenic effects, which in humans are known as fetal alcohol spectrum disorders (FASD). Individuals affected by FASD may exhibit persistent impairments to cognitive functions such as learning, memory, and attention, which are highly dependent on medial prefrontal cortex (mPFC) circuitry. The objective of this study was to determine long-term effects of chronic developmental ethanol exposure on mPFC neuron morphology, in order to better-understand potential neuronal mechanisms underlying cognitive impairments associated with FASD. C57BL/6-strain mice were exposed to ethanol or an isocaloric/isovolumetric amount of sucrose (control) via oral gavage, administered both to the dam from gestational day 10-18 and directly to pups from postnatal day 4-14. Brains from male mice were collected at postnatal day 90 and neurons were stained using a modified Golgi-Cox method. Pyramidal neurons within layers II/III, V and VI of the mPFC were imaged, traced in three dimensions, and assessed using Sholl and branch structure analyses. Developmental ethanol exposure differentially impacted adult pyramidal neuron morphology depending on mPFC cortical layer. Neurons in layer II/III exhibited increased size and diameter of dendrite trees, whereas neurons in layer V were not affected. Layer VI neurons with long apical dendrites had trees with decreased diameter that extended farther from the soma, and layer VI neurons with short apical dendrite trees exhibited decreased tree size overall. These layer-specific alterations to mPFC neuron morphology may form a novel morphological mechanism underlying long-term mPFC dysfunction and resulting cognitive impairments in FASD.

  11. Active fascial contractility: Fascia may be able to contract in a smooth muscle-like manner and thereby influence musculoskeletal dynamics.

    Science.gov (United States)

    Schleip, R; Klingler, W; Lehmann-Horn, F

    2005-01-01

    Dense connective tissue sheets, commonly known as fascia, play an important role as force transmitters in human posture and movement regulation. Fascia is usually seen as having a passive role, transmitting mechanical tension which is generated by muscle activity or external forces. However, there is some evidence to suggest that fascia may be able to actively contract in a smooth muscle-like manner and consequently influence musculoskeletal dynamics. General support for this hypothesis came with the discovery of contractile cells in fascia, from theoretical reflections on the biological advantages of such a capacity, and from the existence of pathological fascial contractures. Further evidence to support this hypothesis is offered by in vitro studies with fascia which have been reported in the literature: the biomechanical demonstration of an autonomous contraction of the human lumbar fascia, and the pharmacological induction of temporary contractions in normal fascia from rats. If verified by future research, the existence of an active fascial contractility could have interesting implications for the understanding of musculoskeletal pathologies with an increased or decreased myofascial tonus. It may also offer new insights and a deeper understanding of treatments directed at fascia, such as manual myofascial release therapies or acupuncture. Further research to test this hypothesis is suggested.

  12. Mutant PIK3CA Induces EMT in a Cell Type Specific Manner.

    Directory of Open Access Journals (Sweden)

    Divya Bhagirath

    Full Text Available Breast cancer is characterized into different molecular subtypes, and each subtype is characterized by differential gene expression that are associated with distinct survival outcomes in patients. PIK3CA mutations are commonly associated with most breast cancer subtypes. More recently PIK3CA mutations have been shown to induce tumor heterogeneity and are associated with activation of EGFR-signaling and reduced relapse free survival in basal subtype of breast cancer. Thus, understanding what determines PIK3CA induced heterogeneity and oncogenesis, is an important area of investigation. In this study, we assessed the effect of mutant PIK3CA together with mutant Ras plus mutant p53 on oncogenic behavior of two distinct stem/progenitor breast cell lines, designated as K5+/K19- and K5+/K19+. Constructs were ectopically overexpressed in K5+/K19- and K5+/K19+ stem/progenitor cells, followed by various in-vitro and in-vivo analyses. Oncogene combination m-Ras/m-p53/m-PIK3CA efficiently transformed both K5+/K19- and K5+/K19+ cell lines in-vitro, as assessed by anchorage-independent soft agar colony formation assay. Significantly, while this oncogene combination induced a complete epithelial-to-mesenchymal transition (EMT in K5+/K19- cell line, mostly epithelial phenotype with minor EMT component was seen in K5+/K19+ cell line. However, both K5+/K19- and K5+/K19+ transformed cells exhibited increased invasion and migration abilities. Analyses of CD44 and CD24 expression showed both cell lines had tumor-initiating CD44+/CD24low cell population, however transformed K5+/K19- cells had more proportion of these cells. Significantly, both cell types exhibited in-vivo tumorigenesis, and maintained their EMT and epithelial nature in-vivo in mice tumors. Notably, while both cell types exhibited increase in tumor-initiating cell population, differential EMT phenotype was observed in these cell lines. These results suggest that EMT is a cell type dependent

    While there is little doubt that sociological theory and research has had an important impact on the way people think about health and health care, mental health and medical sociologists are often confronted with challenges concerning the utility of the work that they do. Among the doubters are deans, funding agencies and family members. We are challenged by the ascendency of biological interpretations of human behaviors, by the incompatibility between the contextual view we prefer and the very strong individualistic orientation of our culture, and by the fact that we do not have an applied arm that trains the professionals who treat health and mental-health conditions. How do we respond to this challenge? The title of this paper gives a short answer: "The Production of Understanding." I propose that a powerful but under-recognized value of our work is the generation of explanations about health and mental health matters that help people understand the other side of an "us"/"them" divide. We produce understanding in a context in which misunderstanding is regularly constructed by powerful people who offer victim-blaming explanations for the circumstances experienced by people with less power. The production of understanding serves as an important counterbalance to this tendency. Our work shapes the way people think about problems related to health and mental health, limits the power of inaccurate victim-blaming accounts and provides understanding about why health and mental health are mal-distributed among people from different social circumstances.

    Full Text Available We evaluated whether the comprehension of sentences that contained numerical information could benefit from presenting numbers in Arabic format and from using prior knowledge. Participants read sentences including numbers (Arabic digits or number words while the comprehension accuracy was evaluated. In addition, the sentences were biased or unbiased by people's prior knowledge about quantities. The results showed better comprehension for sentences that contained Arabic digits as compared to number words. Moreover, biased sentences were understood more accurately than unbiased sentences. These results indicate that information about magnitude in sentence context is comprehended better when quantities are presented in Arabic format and when they are associated with participants' world knowledge.

    Full Text Available A question of interest for educational workers is the reading comprehension process, a fundamental ability for progress in more advanced years of schooling, and its effect on pedagogical practices. This is a study that explores this question. A reading comprehension instrument composed by four structural levels of text and a scale of pedagogical practice composed by four sub-scales involving: cognitive practices with linguistic focus, cognitive practices, affective and motor practices, continuous education, was used. The results of 53 children suggest a slight tendency of teacher to prioritize cognitive practices independently of their reading comprehension level.

    , safety) arise from getting feedback on symptoms and from continuous and comforting interaction with clinicians. With this paper, we aim to sensitise UX researchers and designers of patient-centred e-health by proposing three UX dimensions: connectedness, comprehension, and compassion.......The term 'patient experience' is currently part of a global discourse on ways to improve healthcare. This study empirically explores what patient experience is in cardiac remote monitoring and considers the implications for user experience (UX). Through interviews around the deployment of a mobile...... app that enables patients to collaborate with clinicians, we unpack experiences in six themes and present narratives of patients' lifeworlds. We find that patients' emotions are grounded in negative feelings (uncertainty, anxiety, loss of hope) and that positive experiences (relief, reassurance...

    Full Text Available G protein-coupled receptor 54 (GPR54 is a G(q/11-coupled 7 transmembrane-spanning receptor (7TMR. Activation of GPR54 by kisspeptin (Kp stimulates PIP(2 hydrolysis, Ca(2+ mobilization and ERK1/2 MAPK phosphorylation. Kp and GPR54 are established regulators of the hypothalamic-pituitary-gonadal (HPG axis and loss-of-function mutations in GPR54 are associated with an absence of puberty and hypogonadotropic hypogonadism, thus defining an important role of the Kp/GPR54 signaling system in reproductive function. Given the tremendous physiological and clinical importance of the Kp/GPR54 signaling system, we explored the contributions of the GPR54-coupled G(q/11 and β-arrestin pathways on the activation of a major downstream signaling molecule, ERK, using G(q/11 and β-arrestin knockout mouse embryonic fibroblasts. Our study revealed that GPR54 employs the G(q/11 and β-arrestin-2 pathways in a co-dependent and temporally overlapping manner to positively regulate ERK activity and pERK nuclear localization. We also show that while β-arrestin-2 potentiates GPR54 signaling to ERK, β-arrestin-1 inhibits it. Our data also revealed that diminished β-arrestin-1 and -2 expression in the GT1-7 GnRH hypothalamic neuronal cell line triggered distinct patterns of gene expression following Kp-10 treatment. Thus, β-arrestin-1 and -2 also regulate distinct downstream responses in gene expression. Finally, we showed that GPR54, when uncoupled from the G(q/11 pathway, as is the case for several naturally occurring GPR54 mutants associated with hypogonadotropic hypogonadism, continues to regulate gene expression in a G protein-independent manner. These new and exciting findings add significantly to our mechanistic understanding of how this important receptor signals intracellularly in response to kisspeptin stimulation.

    Full Text Available The influence of internalizing and externalizing problems on children’s understanding of others’ emotions has mainly been investigated on basic levels of emotion comprehension. So far, studies assessing more sophisticated levels of emotion comprehension reported deficits in the ability to understand others’ emotions in children with severe internalizing or externalizing symptoms. The aim of this study was to investigate the relation between emotion comprehension and interindividual differences, with a focus on internalizing and externalizing behavior in children aged 7 to 10 years from the general population. A sample of 135 children was tested for emotion understanding using the Test of Emotion Comprehension. Information on internalizing and externalizing behavior was assessed with the Child Behavior Checklist 4/18. Age, bilingual upbringing, and amount of paternal working hours were significant control variables for emotion comprehension. In contrast to prior research, overall level of emotion understanding was not related to externalizing symptoms and correlated positively with elevated levels of somatic complaints and anxious/depressed symptoms. However, for the internalizing syndrome scales different response patterns in emotion comprehension were found. In addition, and in line with previous work, higher levels of social withdrawal were associated with worse performance in understanding emotions elicited by reminders. The present results implicate not only an altered understanding of emotions among more specific internalizing symptoms, but also that these alterations occur already on a low symptom level in a community based sample.
