    Mechanisms of attention are a prime target for investigating the plasticity of the adult brain, as these core mechanisms act at the intersection of top-down and bottom-up processing, and the wide variety of methods used in attention research can be utilized to elucidate the mechanisms of plasticity. This special issue of Cognitive Neuroscience presents three new empirical papers and a discussion paper with peer commentaries. In the first article, Voelker, Sheese, and colleagues investigate the influence of genetic variation on the effectiveness of attention training. Della Libera and colleagues then present a study investigating how individual differences in personality traits affect the acquisition of reward-based attention biases. In the final empirical paper, Hopfinger and colleagues present a transcranial stimulation study investigating the influence of different oscillatory stimulations on the efficiency of attentional reorienting. Finally, Voelker, Piscopo, and colleagues present a discussion paper in which they suggest that successful training of attention is linked to changes in the underlying white matter. The papers in this special issue present a sampling of the range of issues and methodologies being brought to bear to further our understanding of the malleability of the mechanisms of attention and of the plasticity of the brain.

  7. The impact of new translation technologies on specialized texts

    Full Text Available The introduction of translation technologies, especially translation memory software, has had a significant impact on both the translator’s professional practice and the target text itself. Apart from the fact that he or she must translate in a non-linear fashion due to the design of translation memory systems, the translator is now called upon to increase output and, in many cases, recycle what has already been translated by others. As a result, the translator, used to having full control over his or her text, is in some regards losing control over the translation process, which brings him or her to reflect on the quality of the final product and, in turn, on the transformations the field of specialized translation is undergoing. In this paper, I will present the results of an important ethnographic study conducted in three Canadian translation environments. I will focus mostly on the effects translation technologies and newly implemented practices have had on the quality of specialized texts destined for the Canadian market, where most of the specialized texts produced in French are in fact translations. Special attention will be given to the comments made by specialized translators during semi-directed interviews.

    Full Text Available Purpose. The volume of cargo transportation demands the introduction of a new generation of cars that would be able to provide all the needs of carriers. But this is impossible without the implementation of renovation repair facilities with the introduction of new technologies and modernization of the repair process. Repair of rolling stock is a key factor that must proceed with the establishment of new cars, as not all of the inventions may be repaired in car-repair depots, most of which are obsolete. The purpose is to analyze the possibility of increasing the efficiency of the repair process by introducing new repair technologies or improving the existing ones. It will improve not only the quality of the repair, but also its rate. Methodology. Works on improving the designs of freight cars are held by many design organizations in almost all industrialized countries. It makes repair organizations (depots and car-repair plants to upgrade the repair process. Achievements of-this goal is possible by improving the technology renovation and reorganization through the use of flexible flow technologies, which to date are the most effective in the repair of rolling stock. Findings. When performing the analysis it was determined that there are different designs of cars. More of cars are all-purpose and their repair does not cause difficulties for car-repair business. However, the number of specialized cars is also significant, and the technology of their repair should be improved. One of the reasons is that many models, such as tank wagons for the carriage of sulfur, are intended for the carriage of dangerous goods and their failure at the time of motion is not permitted. Originality. Firstly the authors have defined direction at improving technologies of repair specialized cars. Practical value. Actual improvement in the construction of cars is to improve the existing repair facilities. In addition, the repair technology using nowadays when repairing

    Full Text Available Disabled people face barriers in performing their various activities, including teaching. By using assistive technologies for different activities, people with disabilities may be able to perform a wider range of tasks independently. Fortunately, it helps to reduce many of these barriers, but, unfortunately, disabled people (learning, autism or ADHD face a variety of barriers when they want to use software tools or hardware devices. In this regard, assistive technologies are available to help persons with different types of disabilities, from cognitive problems to physical impairment. Hardware devices and software tools (known as adaptive or assistive technologies have been developed to provide functional alternatives for all individuals with disabilities, depending on the type of disability. In addition, the use of assistive technologies to support them is an effective approach for many persons with disabilities, regardless of the type of disability. Additionally, individuals with disabilities often experience greater success when they are allowed to use their abilities to work around their disabilities (the challenges they imply. Moreover, mobile devices are useful for their ability to weave Internet access and social networking into the daily life. To the people with disabilities, these devices have the potential to unlock unprecedented new possibilities for communication or navigation. In this context, some actual assistive technology and approaches to use them are described in this paper.

    Popp, A.; Lotze-Campen, H.; Dietrich, J.; Klein, D.; Bauer, N.; Krause, M.; Beringer, T.; Gerten, D.

    2011-12-01

    In the coming decades, an increasing competition for global land and water resources can be expected, due to rising demand for agricultural products, goals of nature conservation, and changing production conditions due to climate change. Especially biomass from cellulosic bioenergy crops, such as Miscanthus or poplar, is being proposed to play a substantial role in future energy systems if climate policy aims at stabilizing greenhouse gas (GHG) concentration at low levels. However, the potential of bioenergy for climate change mitigation remains unclear due to large uncertainties about future agricultural yield improvements, land availability for biomass plantations, and implications for the land system. In order to explore the cost-effective contribution of bioenergy to a low carbon transition with special attention to implications for the land system, we present a modeling framework with detailed biophysical and economic representation of the land and energy sector: We have linked the global dynamic vegetation and water balance model LPJmL (Bondeau et al. 2007, Rost et al. 2008), the global land and water use model MAgPIE (Lotze-Campen et al. 2008, Popp et al. 2010), and the global energy-economy-climate model ReMIND (Leimbach et al. 2009). In this modeling framework LPJmL supplies spatially explicit (0.5° resolution) agricultural yields as well as carbon and water stocks and fluxes. Based on this biophysical input MAgPIE delivers cost-optimized land use patterns (0.5° resolution), associated GHG emissions and rates of future yield increases in agricultural production. Moreover, shadow prices are calculated for irrigation water (as an indicator for water scarcity), food commodities, and bioenergy (as an indicator for changes in production costs) under different land use constraints such as forest conservation for climate change mitigation and as a contribution to biodiversity conservation. The energy-economy-climate model ReMIND generates the demand for

    Most students diagnosed with disabilities in Thai special education schools received assistive technologies, but this did not guarantee the greatest benefits. The purpose of this study was to survey the provision, use and needs of assistive technologies, as well as the perspectives of key informants regarding a model of providing them in special education schools. The participants were selected by the purposive sampling method, and they comprised 120 students with visual, physical, hearing or intellectual disabilities from four special education schools in Chiang Mai, Thailand; and 24 key informants such as parents or caregivers, teachers, school principals and school therapists. The instruments consisted of an assistive technology checklist and a semi-structured interview. Results showed that a category of assistive technologies was provided for students with disabilities, with the highest being "services", followed by "media" and then "facilities". Furthermore, mostly students with physical disabilities were provided with assistive technologies, but those with visual disabilities needed it more. Finally, the model of providing assistive technologies was composed of 5 components: Collaboration; Holistic perspective; Independent management of schools; Learning systems and a production manual for users; and Development of an assistive technology center, driven by 3 major sources such as Government and Private organizations, and Schools.

    To describe the parent-reported prevalence of treatments for attention deficit/hyperactivity disorder (ADHD) among a national sample of children with special health care needs (CSHCN), and assess the alignment of ADHD treatment with current American Academy of Pediatrics guidelines. Parent-reported data from the 2009-2010 National Survey of Children with Special Health Care Needs allowed for weighted national and state-based prevalence estimates of medication, behavioral therapy, and dietary supplement use for ADHD treatment among CSHCN aged 4-17 years with current ADHD. National estimates were compared across demographic groups, ADHD severity, and comorbidities. Medication treatment by drug class was described. Of CSHCN with current ADHD, 74.0% had received medication treatment in the past week, 44.0% had received behavioral therapy in the past year, and 10.2% used dietary supplements for ADHD in the past year. Overall, 87.3% had received past week medication treatment or past year behavioral therapy (both, 30.7%; neither, 12.7%). Among preschool-aged CSHCN with ADHD, 25.4% received medication treatment alone, 31.9% received behavioral therapy alone, 21.2% received both treatments, and 21.4% received neither treatment. Central nervous system stimulants were the most common medication class (84.8%) among CSHCN with ADHD, followed by the selective norepinephrine reuptake inhibitor atomoxetine (8.4%). These estimates provide a benchmark of clinical practice for the period directly preceding issuance of the American Academy of Pediatrics' 2011 ADHD guidelines. Most children with ADHD received medication treatment or behavioral therapy; just under one-third received both. Multimodal treatment was most common for CSHCN with severe ADHD and those with comorbidities. Approximately one-half of preschoolers received behavioral therapy, the recommended first-line treatment for this age group. Published by Elsevier Inc.

    The hagfish liver was histochemically examined with special attention to biliary structures around the portal veins. Hepatocytes were organized into tubular structures surrounded by sinusoids. Biliary ductule structures, which resemble the ductal plates transiently appearing in mammalian liver development, were observed around the portal veins, but they did not appear around central veins. Thus, the hagfish liver demonstrates the same basic structure as the mammalian liver; that is, a vascular system from portal to central veins via sinusoids, and portal triad structures consisting of portal veins, hepatic arteries, and intrahepatic bile ducts. The epithelial cells of the ductal platelike structures strongly expressed cytokeratin, had some lectin-binding sites, and were delineated by the basal lamina, which was reactive for periodic acid-Schiff (PAS) staining and Iectin histochemistry. The lumina of the ductal plate-like structures were comparatively small and heterogeneous in diameter around the portal veins, suggesting that the biliary structures may not be efficient for bile secretion. The epithelial cells of the gall bladder had a simple columnar shape and were a PAS-positive cytoplasm. Those of bile ducts near the hilus, including extrahepatic and hepatic ducts, were simple columnar or cuboidal cells, and had large lumina. The cytoplasm in these cells was PAS-positive. These phenotypes with the expression of lectin-binding sites were clearly different from those of the ductal plate-like structures in the liver proper, suggesting that the extrahepatic and intrahepatic biliary structures may have different developmental origins.

  10. Large impacts in the Baltic shield with special attention to the Uppland structure

    Science.gov (United States)

    Henkel, H.; Lilljequist, R.

    1992-01-01

    Within the Baltic Shield several very large structures have been identified and are suspected to be of meteorite impact origin. Some of these deeply eroded circular features are presented with special attention to the Uppland structure, where several indications point toward an impact origin in the mid-Proterozoic. The structures exceed 100 km in diameter and the topographic expression is inferior or absent. An arcuate arrangement of lithologies occurs around the margin of the structures and the central regions show conform magnetic and positive gravity anomalies. The Uppland structure is approximately 320 km in diameter as expressed by morphological, geological, and geophysical concentric patterns. The central part is topographically remarkably flat and is characterized by an unusual irregular fracture pattern. A subcircular central tonalite with density of 2.81 Mg(sup -3) gives a positive gravity anomaly of 35 mgal and the gravimetric profile is very similar to that of Manicouagan and Vredefort. The tonalite constitutes a huge antiform, 80 km in diameter, probably representing a 12-km structural uplift of infracrustal rocks. The flancs of the tonalite are characterized by recrystallized pseudotachylitic breccia dykes and breccia zones. Around the central parts amphibolite-grade metamorphic rocks appear as large fragments within a fine-grained granite interpreted as a thermally annealed melt rock. Several occurrences of breccia dykes and breccia-bearing melts have been identified about 100 km from the gravimetric center of the structure. Impact-related ore deposits are located around the margin of the structure and are interpreted as preexisting downfaulted iron formations, and deposits formed from remobilization of these preimpact occurrences. The so-called ball ores are interpreted to have formed by fluid injection similar to the formation of breccia dykes. The extensive hydrothermal alteration along the outer margin of the structure have created extreme soda

    Full Text Available The ability to select information that is relevant to current behavioral goals is the hallmark of voluntary attention and an essential part of our cognition. Attention tasks are a prime example to study at the neuronal level, how task related information can be selectively processed in the brain while irrelevant information is filtered out. Whereas, numerous studies have focused on elucidating the mechanisms of visual attention at the single neuron and population level in the visual cortices, considerably less work has been devoted to deciphering the distinct contribution of higher-order brain areas, which are known to be critical for the employment of attention. Among these areas, the prefrontal cortex (PFC has long been considered a source of top-down signals that bias selection in early visual areas in favor of the attended features. Here, we review recent experimental data that support the role of PFC in attention. We examine the existing evidence for functional specialization within PFC and we discuss how long-range interactions between PFC subregions and posterior visual areas may be implemented in the brain and contribute to the attentional modulation of different measures of neural activity in visual cortices.

    Full Text Available Pharmaceuticals and personal care products (PPCPs have received increasing attention. However, their transformation products (TPs and metabolites, sometimes even with environmental concentration and/or toxicity higher than their parent compounds, received attention far from enough. This study gives useful insight on the occurrence, fate and toxicity of PPCP TPs or metabolites in WWTPs, surface water and even drinking water, highlighting the necessity of studying the PPCP TPs formation, occurrence, toxicity and environment risk, and further evaluating the environmental risk caused by PPCPs comprehensively.

  6. Faces do not capture special attention in children with autism spectrum disorder: a change blindness study.

    Science.gov (United States)

    Kikuchi, Yukiko; Senju, Atsushi; Tojo, Yoshikuni; Osanai, Hiroo; Hasegawa, Toshikazu

    2009-01-01

    Two experiments investigated attention of children with autism spectrum disorder (ASD) to faces and objects. In both experiments, children (7- to 15-year-olds) detected the difference between 2 visual scenes. Results in Experiment 1 revealed that typically developing children (n = 16) detected the change in faces faster than in objects, whereas children with ASD (n = 16) were equally fast in detecting changes in faces and objects. These results were replicated in Experiment 2 (n = 16 in children with ASD and 22 in typically developing children), which does not require face recognition skill. Results suggest that children with ASD lack an attentional bias toward others' faces, which could contribute to their atypical social orienting.

    applications). The paper by Flores-Rodriguez and Markz presents a study on one aspect of this discipline. Presentations on meta- and structured materials at the conference are represented here in two papers: those of Shamonina and Solymar and of Zhou, Chan and Sheng, while a study in the closely allied area of band-gap materials is presented in the paper by Schuster and Klein. The final paper from the conference in this special cluster is concerned with an end-use application: the use of tuneable dielectric resonators in base-stations for future mobile telecoms networks. The paper by Krupka et al describes a magnetic approach to such tuning. In the longer term we sincerely hope that both the conference and these papers will prove to have made a significant contribution to the development and uses of dielectrics, and their metamaterial derivatives, in advanced technological applications. It is noteworthy that as a result of the success of this conference, the 2004 annual conference will be on the subject of `Dielectrics at Meso- and Nano-Scales'. We would like to take this opportunity to express our sincere thanks to all who participated in the conference for their contributions and we would like to express our particular thanks to the authors of the papers in this special cluster of Journal of Physics D: Applied Physics.

    Dr. Mehmet Firat

    2013-07-01

    Full Text Available Continuous Partial Attention is a current concept open to research which, besides multitasking, intensely occupies the agenda of education, communication and cognitive psychology. The purpose of the present study was to determine educators’ continuous partial attention. In line with this purpose, the research data were collected from 109 educators in higher education from different age groups and from four different countries with the use of a questionnaire made up of two sections and seven questions. The findings obtained in the study revealed that the educators’ Continuous Partial Attention did not significantly differ with respect to their technology use efficacies, their ages or their countries. In addition, it was found out that the educators’ Continuous Partial Attention differed statistically significantly depending on the fields they worked in. Based on this, it could be stated that educators working in the field of educational technologies encounter with Continuous Partial Attention more frequently than educators working in other fields. At the end of the study, several suggestions were put forward.

    The aim was to evaluate the actual health conditions of children subject to family reunification at the time of their introductory examination at their Danish school and to estimate whether these children represent any health risk to others at the school. The focus was the children's somatic disease pattern and not the behavioural and psychopathological aspects. A prospective analysis was carried out of children subject to family reunification who started school in Copenhagen in the school year, 1999/2000. This analysis is based on a family interview with the aid of a translator and an objective medical examination. In the school year 1999/2000, 148 children were examined. They were aged between 5 and 18 years. The children had emigrated from 25 different countries. Fifty-five children live with only one biological parent. Eighteen point five per cent of the children have earlier had one or more diseases. Most of them (91.2%) were assessed as having good general health and sensomotoric development according to their age. Among the 148 children examined, 48% have had one or more diagnoses made. On the basis of the experience obtained in this study, more resources must be allocated for better examination. In the light of the pattern of disease, it cannot be concluded that the children constitute a risk of infection for other children and adults at school. The results of this study call attention to a need for prospective studies on the health conditions of the children subject to family reunification on their arrival in Denmark.

    Full Text Available Bulimia nervosa is a serious and complex health problem encountered by many professionals, including general practitioners and dentists. The aim of the study was to describe the problem of bulimia (its prevalence, symptoms, special situations, treatment, with particular emphasis on the aspect of the oral health. The paper presents the causes and factors contributing to the disease, diagnostic criteria, the onset and the possible course of the disease, dental and oral mucosa pathologies due to bulimia as well as other comorbidities (including diabetes. The paper is of descriptive nature. The research method was based on the analysis of the available literature on bulimia nervosa supplemented by our own experience. It was concluded based on the analysed sources that appropriate diagnosis and treatment of bulimia nervosa is possible only with the cooperation of many specialists: psychiatrists or paediatric psychiatrists, dentists and general practitioners as well as other doctors if necessary. Psychotherapy is a necessary and integral aspect of treatment. Early treatment onset is essential for good treatment outcomes. Due to the low sense of illness, some patients would never meet a psychiatrist if not for the intervention of a family doctor or a dentist.

  15. Prediction of Tonal Underwater Noise Pattern from Cavitating Propellers with Special Attention to Ice Cover Effects

    Directory of Open Access Journals (Sweden)

    Streckwall Heinrich

    2015-01-01

    Full Text Available To predict underwater noise spectra associated to regular occurrence of propeller cavitation we have extended an existing method [1] (used for the prediction of fluctuating hull pressures to become applicable for effects that are linked to a finite speed of sound. In [2] an intermediate approach was realized where (besides the hull far field boundaries were introduced but the incompressible flow assumption was kept. However compressibility effects become noticeable in the far field, which may be judged to start at some 2-3 propeller-diameters distance from the centre of the cavitation events, if we confine to emissions at 1st-4th blade frequency. It was a logical continuation of our former efforts to realize a compressible flow model and integrate the propeller as a noise source. Having increased the functionality of our approach by referencing the speed of sound, the precision of the method was also somehow reduced. In our former approach, like in comparable approaches (see for instance [3] and [4], the singularity system generating the near field propeller induced pressures involved various sources and vortices distributed on the propeller blades. With our current compressible approach this complexity was dropped, as a single point source substitutes the cavitating propeller. Such a simplification correlates with the assumption, that the monopole character of a noise source is decisive for the far field noise levels. In this contribution we outline the steps characterizing the procedure for predicting tonal underwater noise from cavitating propellers. In the first step a Vortex Lattice Method (VLM is used to access the cavitation pattern on the propeller with special focus on the cavity volume attached to one blade. The second step accumulates the distributed cavities to establish a fluctuating point source of equivalent far field noise characteristic. As relevant limits the hull, the free surface, the sea bottom and an ice cover are

  1. Current State and Model for Development of Technology-Based Care for Attention Deficit Hyperactivity Disorder.

    Science.gov (United States)

    Benyakorn, Songpoom; Riley, Steven J; Calub, Catrina A; Schweitzer, Julie B

    2016-09-01

    Care (i.e., evaluation and intervention) delivered through technology is used in many areas of mental health services, including for persons with attention deficit hyperactivity disorder (ADHD). Technology can facilitate care for individuals with ADHD, their parents, and their care providers. The adoption of technological tools for ADHD care requires evidence-based studies to support the transition from development to integration into use in the home, school, or work for persons with the disorder. The initial phase, which is development of technological tools, has begun in earnest; however, the evidence base for many of these tools is lacking. In some instances, the uptake of a piece of technology into home use or clinical practice may be further along than the research to support its use. In this study, we review the current evidence regarding technology for ADHD and also propose a model to evaluate the support for other tools that have yet to be tested. We propose using the Research Domain Criteria as a framework for evaluating the tools' relationships to dimensions related to ADHD. This article concludes with recommendations for testing new tools that may have promise in improving the evaluation or treatment of persons with ADHD.

    Mindfulness training (MT) programs represent an approach to attention training with well-validated mental health benefits. However, research supporting MT efficacy is based predominantly on weekly-meeting, facilitator-led, group-intervention formats. It is unknown whether participants might benefit from neurofeedback-assisted, technology-supported MT (N-tsMT), in which meditation is delivered individually, without the need for a facilitator, travel to a training site, or the presence of a supportive group environment. Mirroring the validation of group MT interventions, the first step in addressing this question requires identifying whether N-tsMT promotes measurable benefits. Here, we report on an initial investigation of a commercial N-tsMT system. In a randomized, active control trial, community-dwelling healthy adult participants carried out 6 weeks of daily practice, receiving either N-tsMT (n = 13), or a control condition of daily online math training (n = 13). Training effects were assessed on target measures of attention and well-being. Participants also completed daily post-training surveys assessing effects on mood, body awareness, calm, effort, and stress. Analysis revealed training effects specific to N-tsMT, with attentional improvements in overall reaction time on a Stroop task, and well-being improvements via reduced somatic symptoms on the Brief Symptom Inventory. Attention and well-being improvements were correlated, and effects were greatest for the most neurotic participants. However, secondary, exploratory measures of attention and well-being did not show training-specific effects. N-tsMT was associated with greater body awareness and calm, and initially greater effort that later converged with effort in the control condition. Preliminary findings indicate that N-tsMT promotes modest benefits for attention and subjective well-being in a healthy community sample relative to an active control condition. However, the findings would benefit

    In this research the authors examined middle school special education teachers' perceptions of assistive technology during literacy instruction with students with high incidence disabilities. A survey explored the use, effectiveness, and factors impacting use or effectiveness of assistive technology for literacy teaching and learning. Results suggested teachers' perceived assistive technology to be an effective tool for literacy, but use it minimally. When assistive technology was used, teachers indicated it was an effective literacy support. Teachers also reported barriers to using assistive technology in literacy including cost, usability, and lack of training/experience. However, factors such as previous successful experiences with assistive technology and assistive technology supporting students' learning encouraged assistive technology use. The consistency of teachers' reports of needing more experience and knowledge in assistive technology to fully use it suggests implications for preservice preparation such as providing additional experiences and information on assistive technology.

In U.S.A, the National Aeronautics and Space Administration and the U.S. Army Natick Soldier RD and E Center co-developed the hazard analysis of critical control point, which is a essential hygienic control system in food industry. Moreover, strict manufacturing standards to produce shelf-stable foods using radiation (ionizing energy) technology were established. In Korea, the advanced food technologies to sterilize various foods using irradiation technology were expected to be applied as a hygiene process on group meals and ready-to-eat/ready-to cook foods, and to produce foods for patients with high hygienic, nutritional, and organoleptic qualities through the combination treatments with irradiation technology. And, it was considered that the advanced technology would improve the related industries and national economy by introducing the food irradiation technology to the Korean traditional fermented foods to improve their functionality. In conclusion, the advanced food technologies which are preoccupied by some developed countries like U.S.A. and Russia will make a contribution to the development of national science and technology, and competitiveness promotion of industry.

    2010-09-07

    Attention-Deficit/Hyperactivity Disorder (ADHD) is a mental disorder. Symptoms include hyperactivity, lack of attentiveness, and frivolousness. This disorder always begins in childhood, but can remain through adulthood. ADHD affects all areas of life and limits the quality of life due to its symptoms and the high rate of associated disorders that can develop. An established form of therapy is using stimulant medications, most commonly, containing Methylphenidate as the active ingredient. However, in Germany this ingredient is not approved for adults suffering from ADHD. Therefore, many adults cannot obtain appropriate medication to treat this disorder. The following report (Health Technology Assessment [HTA]) examines the effectiveness and cost-effectiveness of the medical treatment of ADHD in adults as well as the ethical, social and legal aspects thereof. In August 2009, a systematic literature search is performed in all relevant scientific databases. The selected citations fulfill predetermined inclusion criteria. The data in the publications is then systematically extracted, reviewed and assessed. A manual search of citations is conducted as well. NINETEEN STUDIES FULFILL THE INCLUSION CRITERIA: nine randomised controlled studies (RCT), five meta-analyses, three economic studies and two studies relevant to the legal aspects of the HTA. All RCT reveal that adult patients who receive medication containing a stimulant (Methylphenidate and Amphetamine) and Atomoxetine, see a reduction of ADHD symptoms compared to the placebo-treated patients. The drug response rate among the control group ranges from 7 to 42%; in the treatment group from 17 to 59.6%. The meta-analyses confirm the findings of the RCT. In light of the control group, it can be ascertained that there are higher annual costs (both direct and indirect) for patients with ADHD. The average annual medical expenses for an adult with ADHD were 1,262 $ in 1998 and 1,673 $ in 2001 (the converted and inflation

    Although not widely recognized, tooth decay is the most common childhood chronic disease among children ages five to seventeen. Despite higher rates of dental caries and greater needs, low-income minority children enrolled in Medicaid are more likely to go untreated relative to their higher income counterparts. No research has examined this issue for children with special needs. We analyzed Medicaid enrollment and claims data for special-needs children enrolled in the District of Columbia Medicaid program to evaluate receipt of recommended preventive dental care. Use of preventive dental care is abysmally low and has declined over time. Enrollment in managed care rather than fee for service improves the likelihood that special-needs children receive recommended preventive dental services, whereas residing farther from the Metro is an impediment to receipt of dental care.

    Youth with learning disorders, speech/language disorders, and/or attention-deficit/hyperactivity disorder may experience significant struggles during the transition from high school to postsecondary education and employment. These disorders often occur in combination or concurrently with behavioral and emotional difficulties. Incomplete evaluation may not fully identify the factors underlying academic and personal challenges. This article reviews these disorders, the role of special education law for transitional age youth in public schools, and the Americans with Disabilities Act in postsecondary educational and employment settings. The role of the child and adolescent psychiatrist and the importance of advocacy for these youth are presented. Copyright © 2017 Elsevier Inc. All rights reserved.

    Different dietary approaches have been attempted for the treatment of attention-deficit/hyperactivity disorder and autism, but only three of them have been subjected to clinical trials: education in healthy nutritional habits, supplementation and elimination diets. On the other hand, for multiple reasons, the number of people who adopt vegetarian and gluten-free diets (GFD) increases daily. More recently, a new entity, non-celiac gluten sensitivity (NCGS), with a still evolving definition and clinical spectrum, has been described. Although, the benefits of GFD are clearly supported in this condition as well as in celiac disease, in the last two decades, GFD has expanded to a wider population. In this review, we will attempt to clarify, according to the existing evidence, which are the myths and facts of these diets. © 2016 S. Karger AG, Basel.

    Comorbidity between ADHD and Bipolar Disorder (BD) is associated with greater severity of BD. The current study aims at investigating, in a specialized mood disorders clinic, the percentage of comorbid ADHD-BD subjects and assessing the impact of ADHD on the severity of BD. Out of 539 mood disorders subjects, the medical records of 138 BD subjects were scrutinized in terms of their clinical and demographic characteristics, and their scores at the Adult ADHD Self-Report Scale (ASRS-v1.1) Symptom Checklist were logged. Those positively scoring at the ASRS-v1.1 underwent clinical assessment by a senior psychiatrist specialized in ADHD. Comorbid ADHD-BD subjects were then compared with BD sufferers without ADHD. Sixty-three (45.65%) of the participants were screened positive at the ASRS-v1.1. 49 were clinically assessed for the presence of ADHD. Only 27 (55%) received a diagnosis of ADHD. Comorbid ADHD-BD subjects were found to be younger at the onset of BD, showed higher numbers of depressive episodes, more anxiety and substance use disorders, more borderline personality traits and greater cyclothymic temperament. Comorbid BD-ADHD subjects reported more childhood emotional abuse. Some subjects were unreachable and thus not clinically assessed for ADHD. More than 20% of BD subjects were suffering from ADHD. The comorbidity of the two disorders was associated with worse outcomes, possibly resulting from stressful early-life events. More than 40% of the subjects who scored positively at the ASRS-v1.1 did not suffer from ADHD, which suggests that this scale should be used with caution in BD subjects.

    Nuclear deterrence, a cornerstone of US national security policy, has helped prevent global conflict for over 40 years. The DOE and DoD share responsibility for this vital part of national security. The US will continue to rely on nuclear deterrence for the foreseeable future. In the late 1950s, Sandia developed satellite-borne nuclear burst detection systems to support the treaty banning atmospheric nuclear tests. This activity has continued to expand and diversify. When the Non-Proliferation Treaty was ratified in 1970, we began to develop technologies to protect nuclear materials from falling into unauthorized hands. This program grew and now includes systems for monitoring the movement and storage of nuclear materials, detecting tampering, and transmiting sensitive data securely. In the late 1970s, negotiations to further limit underground nuclear testing were being actively pursued. In less than 18 months, we fielded the National Seismic Station, an unattended observatory for in-country monitoring of nuclear tests. In the mid-l980s, arms-control interest shifted to facility monitoring and on-site inspection. Our Technical On-site Inspection Facility is the national test bed for perimeter and portal monitoring technology and the prototype for the inspection portal that was recently installed in the USSR under the Intermediate-Range Nuclear Forces accord. The articles in the special issue of Sundiu Technology describe some of our current contributions to verification technology. This work supports the US policy to seek realistic arms control agreements while maintaining our national security.

    Full Text Available Working memory impairments are frequent in Attention Deficit/Hyperactivity Disorder (ADHD and create problems along numerous functional dimensions. The present study utilized the Visual Serial Addition Task (VSAT and functional magnetic resonance imaging (fMRI to explore working memory processes in thirteen typically developing (TD control and thirteen children with ADHD, Combined type. Analysis of Variance (ANOVA was used to examine both main effects and interactions. Working memory-specific activity was found in TD children in the bilateral prefrontal cortex. In contrast the within-group map in ADHD did not reveal any working-memory specific regions. Main effects of condition suggested that the right middle frontal gyrus (BA6 and the right precuneus were engaged by both groups during working memory processing. Group differences were driven by significantly greater, non-working memory-specific, activation in the ADHD relative to TD group in the bilateral insula extending into basal ganglia and the medial prefrontal cortex. A region of interest analysis revealed a region in left middle frontal gyrus that was more active during working memory in TD controls. Thus, only the TD group appeared to display working memory-modulated brain activation. In conclusion, children with ADHD demonstrated reduced working memory task specific brain activation in comparison to their peers. These data suggest inefficiency in functional recruitment by individuals with ADHD represented by a poor match between task demands and appropriate levels of brain activity.

    Low attention to dairy product consumptions and high intake of junk foods and bakery products might be related to high prevalence of chronic diseases because of their fat content and fatty acid composition. In this study we investigated the kind and amount of fatty acid content in Iranian junk foods, dairy, and bakery products. Some common brands of Iranian's junk foods, dairy, and bakery products were chosen randomly from different supermarkets in Iran. The amount of 10 g sample was considered for fatty acid analysis by gas chromatography equipment with flam ionization detector. In this study stearic acid (C18:0) and palmitic (C16:0) acid have the highest amount among other saturated fatty acids in all groups. In junk foods and bakery products, the most common trans-fatty acid (TFA) is elaidic acid (C18:1 9t) with ranging from 2.4% to 18.5% and in dairy products vaccinic acid (C18:1 11t) has the high level of TFAs among others (2.1% to 11.5%). The amount of TFAs in Iranian junk foods and bakery products was in a high level.

    Full Text Available Residual sludge disposal costs may constitute up to, and sometimes above, 50% of the total cost of operation of a Wastewater Treatment Plant (WWTP and contribute approximately 40% of the total greenhouse gas (GHG emissions associated with its operation. Traditionally, wastewater sludges are processed for: (a reduction of total weight and volume to facilitate their transfer and subsequent treatments; (b stabilization of contained organic material and destruction of pathogenic microorganisms, elimination of noxious odors, and reduction of putrefaction potential and, at an increasing degree; (c value addition by developing economically viable recovery of energy and residual constituents. Among several other processes, pyrolysis of sludge biomass is being experimented with by some researchers. From the process, oil with composition not dissimilar to that of biodiesels, syngas, and a solid residue can be obtained. While the advantage of obtaining sludge-derived liquid and gaseous fuels is obvious to most, the solid residue from the process, or char (also indicated as biochar by many, may also have several useful, initially unexpected applications. Recently, the char fraction is getting attention from the scientific community due to its potential to improve agricultural soils’ productivity, remediate contaminated soils, and supposed, possible mitigation effects on climate change. This paper first discusses sludge-pyrolysis-derived char production fundamentals (including relationships between char, bio-oil, and syngas fractions in different process operating conditions, general char properties, and possible beneficial uses. Then, based on current authors’ experiments with microwave-assisted sludge pyrolysis aimed at maximization of liquid fuel extraction, evaluate specific produced char characteristics and production to define its properties and most appropriate beneficial use applications in this type of setting.

    1998-07-01

    The rationale for the development of over-the-horizon (OTH) radar systems operating at frequencies in the HF band arose out of a perceived need for an early-warning defense network. That need changed with the end of the Cold War; however, today OTH radars play a major role in the CounterDrug Program for the interdiction of drug-smuggling aircraft. This special section of Radio Science is devoted to a review of OTH radar technology, with emphasis on contemporary developments in this field. The collection of papers presented here has evolved largely from research and development efforts directed to improving the performance of OTH radar systems deployed both in the United States and in Australia.

    Nano device prototyping (NDP) is essential for realizing and assessing ideas as well as theories in the form of nano devices, before they can be made available in or as commercial products. In this review, application results patterned similarly to those in the semiconductor industry (for cell phone, computer processors, or memory) will be presented. For NDP, some requirements are different: thus, other technologies are employed. Currently, in NDP, for many applications direct write Gaussian vector scan electron beam lithography (EBL) is used to define the required features in organic resists on this scale. We will take a look at many application results carried out by EBL, self-organized 3D epitaxy, atomic probe microscopy (scanning tunneling microscope/atomic force microscope), and in more detail ion beam techniques. For ion beam techniques, there is a special focus on those based upon liquid metal (alloy) ion sources, as recent developments have significantly increased their applicability for NDP.

Nevertheless, current technology generally requires damaging doses of UV or violet illumination and the continuous re-introduction of the caged compound, which, despite interest, makes for a difficult transition beyond in vitro preparations. Thus, the tremendous progress in the in vivo application of photo-stimulation tools over the past five years has been largely facilitated by two 'exciting' new photo-stimulation technologies: photo-biological stimulation of a rapidly increasing arsenal of light-sensitive ion channels and pumps ('optogenetic' probes[15-18]) and direct photo-thermal stimulation of neural tissue with an IR laser [19-21]. The Journal of Neural Engineering has dedicated a special section in this issue to highlight advances in optical stimulation technology, which includes original peer-reviewed contributions dealing with the design of modern optical systems for spatial-temporal control of optical excitation patterns and with the biophysics of neural-thermal interaction mediated by electromagnetic waves. The paper by Nikolenko, Peterka and Yuste [22] presents a compact design of a microscope-photo-stimulator based on a transmissive phase-modulating spatial-light modulator (SLM). Computer-generated holographic photo-stimulation using SLMs [12-14, 23] allows the efficient parallel projection of intense sparse patterns of light, and the welcome development of compact, user-friendly systems will likely reduce the barrier to its widespread adoption. The paper by Losavio et al [24] presents the design and functional characteristics of their acousto-optical deflector (AOD) systems for studying spatial-temporal dendritic integration in single neurons in vitro. Both single-photon (UV) and two-photon (femtosecond pulsed IR) AOD uncaging systems are described in detail.

    Guidelines in the United Kingdom recommend that medication titration for attention deficit hyperactivity disorder (ADHD) should be completed within 4-6 weeks and include regular reviews. However, most clinicians think that weekly clinic contact is infeasible, and audits have shown that this timeline is rarely achieved. Thus, a more effective monitoring and review system is needed; remote monitoring technology (RMT) may be one way to improve current practice. However, little is known about whether patients with ADHD, their families, and clinicians would be interested in using RMT. To explore patients', parents', and health care professionals' views and attitudes toward using digital technology for remote monitoring during titration for ADHD. This was a qualitative study, and data were collected through 11 focus groups with adults and young people with ADHD, parents of children with ADHD, and health care professionals (N=59). All participant groups were positive about using RMT in the treatment of ADHD, but they were also aware of barriers to its use, especially around access to technology and integrating RMT into clinical care. They identified that RMT had the most potential for use in the ongoing management and support of ADHD, rather than during the distinct titration period. Participants identified features of RMT that could improve the quality of consultations and support greater self-management. RMT has the potential to augment support and care for ADHD, but it needs to go beyond the titration period and offer more to patients and families than monitoring through outcome measures. Developing and evaluating an mHealth app that incorporates the key features identified by end users is required.

    Full Text Available Background Given that the majority of children with attention deficit hyperactivity disorder (ADHD attend regular classroom settings in Germany, it is necessary for teachers to be well prepared to provide these children appropriate care and education on the basis of accurate knowledge of ADHD. Pre-service teachers should have enough learning possibilities in their curriculum about ADHD. The purpose of this study was to investigate German pre-service teachers’ knowledge of ADHD by differentiating between their future school type, their study progress, their learning experiences, gender, and age. Participants and procedure The participants were 234 pre-service teachers of the University of Leipzig, Germany. The survey instrument constructed by Lee (2015 was slightly modified for pre-service teachers, and consists of the three subscales: (a characteristics of ADHD, (b causes of ADHD, and (c subtypes of ADHD. Results Total accuracy of the knowledge of German pre-service teachers was 51.60%, inaccuracy was 21.60%, and no information was 25.80%. German pre-service teachers who majored in special education have a significantly higher accuracy rate than those who majored in primary education. The knowledge profiles consisting of total knowledge score and three domain-specific subscores can be explained significantly (ANOVAs by the main effects and the interactions among the independent factors (a future school type, (b study progress, (c experience by curriculum, and (d personal experience. It was possible to discriminate significantly four pre-service teacher groups (differentiated by future school type and study progress on the basis of their knowledge profiles by a discriminant analysis. Conclusions Teachers are an important target group for ADHD research because they play a major role in early diagnosis of ADHD as well as supporting their development. During their education, pre-service teachers need to be prepared for dealing appropriately with

    2011-11-01

    Fast, nondestructive and accurate identification of special quality eggs is an urgent problem. The present paper proposed a new feature extraction method based on symbol entropy to identify near infrared spectroscopy of special quality eggs. The authors selected normal eggs, free range eggs, selenium-enriched eggs and zinc-enriched eggs as research objects and measured the near-infrared diffuse reflectance spectra in the range of 12 000-4 000 cm(-1). Raw spectra were symbolically represented with aggregation approximation algorithm and symbolic entropy was extracted as feature vector. An error-correcting output codes multiclass support vector machine classifier was designed to identify the spectrum. Symbolic entropy feature is robust when parameter changed and the highest recognition rate reaches up to 100%. The results show that the identification method of special quality eggs using near-infrared is feasible and the symbol entropy can be used as a new feature extraction method of near-infrared spectra.

    Full Text Available Background: Attention-Deficit/Hyperactivity Disorder (ADHD is a mental disorder. Symptoms include hyperactivity, lack of attentiveness, and frivolousness. This disorder always begins in childhood, but can remain through adulthood. ADHD affects all areas of life and limits the quality of life due to its symptoms and the high rate of associated disorders that can develop. An established form of therapy is using stimulant medications, most commonly, containing Methylphenidate as the active ingredient. However, in Germany this ingredient is not approved for adults suffering from ADHD. Therefore, many adults cannot obtain appropriate medication to treat this disorder. Objective: The following report (Health Technology Assessment [HTA] examines the effectiveness and cost-effectiveness of the medical treatment of ADHD in adults as well as the ethical, social and legal aspects thereof. Methods: In August 2009, a systematic literature search is performed in all relevant scientific databases. The selected citations fulfill predetermined inclusion criteria. The data in the publications is then systematically extracted, reviewed and assessed. A manual search of citations is conducted as well. Results: Nineteen studies fulfill the inclusion criteria: nine randomised controlled studies (RCT, five meta-analyses, three economic studies and two studies relevant to the legal aspects of the HTA.All RCT reveal that adult patients who receive medication containing a stimulant (Methylphenidate and Amphetamine and Atomoxetine, see a reduction of ADHD symptoms compared to the placebo-treated patients. The drug response rate among the control group ranges from 7 to 42%; in the treatment group from 17 to 59.6%. The meta-analyses confirm the findings of the RCT. In light of the control group, it can be ascertained that there are higher annual costs (both direct and indirect for patients with ADHD. The average annual medical expenses for an adult with ADHD were 1,262 $ in

    This laboratory study compared a specially engineered sonic powered toothbrush with unique sensing and control technologies and having two different brush heads to a manual flat-trim toothbrush for their ability to remove plaque at interproximal sites. Interproximal access efficacy (IAE) was measured as the maximum width of plaque removed from the artificial plaque substrate around the teeth. Six brushes of each product were tested four times for a total of 24 tests. Results from these tests were statistically analyzed using an analysis of variance (ANOVA). A post hoc Tukey test for pair-wise comparisons, with a minimum significance level of 0.05, was used to identify significant mean differences between the test products. Relative to the manual flat-trim toothbrush, the sonic powered toothbrush, equipped with either the Triple Clean or Sensitive refill brush head, had statistically significantly higher IAE means (p toothbrush showed increased efficiencies compared to when it was equipped with the Triple Clean brush head with respect to IAE means. The specially engineered sonic powered toothbrush with unique sensing and control technologies had higher interproximal access efficacy compared to a manual flat-trim toothbrush, particularly with the Sensitive brush head.

  10. The Unsuspected Roles of Chemistry in Nuclear Power Plants: Special Chemical Technologies for Enhanced Safety and Increased Performance

    Sempere Belda, Luis

    2008-01-01

    The plant's chemists main responsibility is the establishment and monitoring of an adequate water chemistry to minimize corrosion and in PWRs, to control the neutron flux. But this is by no means the only way in which chemical applications contribute to the performance and safety of a NPP during its entire life: The use of special coatings and treatment protects the plant's components from aggressive environmental conditions. The chemical scale removal in steam generators improves the power output of aging plants, helping even to achieve permissions for NPP life extension. The use of special adhesives can replace welding in complicated or high-dose areas, even underwater. And chemical decontamination is used to remove activity from the components of the primary circuit prior to maintenance or replacement works in order to decrease the radiation exposure of the plant's personnel, employing revolutionary methods of waste minimization to limit the amount of generated radioactive waste to a minimum. The AREVA Group, in its pursue of excellence in all stages of the nuclear cycle, has devoted years of research and development to be able to provide the most advanced technological solutions in this field. The awareness of the existing possibilities will help present and future nuclear professionals, chemists and non-chemists alike, to benefit from the years of experience and continuous development in chemical technologies at the service of the nuclear industry.

    This study analyzes the issue attention cycle for print and online media coverage of a scientific publication examining the deaths of Chinese factory workers due to lung damage from chronic exposure to nanoparticles. The results of the nanoparticle study, published in 2009, embody news values that would make the study a prime candidate for press coverage, namely, novelty, negativity, controversy, and potential widespread impact. Nevertheless, mentions of the event in traditional English-language print media were nearly nonexistent. Online media, on the other hand, gave the story greater coverage. This case study exemplifies why online media may not be bound to the same issue attention cycle that print media are for controversial scientific events.

    With financial support from the German Minister of Research and Technology (BMFT) two German companies have developed two GPS-C/A-Code-receivers for different applications with low weight and small volume. The measured results of positions in connection with the ABS of a car (Anti lock braking system) and in Diff.-GPS-mode are very satisfying and in the range of 15 and/or 3 meters. Both receivers worked quite well and both companies have demonstrated their capability to meet our high exspectations. Unfortunately the GPS-satellite to be launched are behind schedule, therefore the two German companies cannot sell their products and if the GPS-system will be completed in the year 1991 other technologies with smaller and cheaper receivers will be on the market.

    Full Text Available In this paper we claim that the current approach to learning objects and metadata standards is counter productive for the integration of e-learning in higher education. We explain why higher education is different with regard to E-learning and we suggest an approach that avoids the use of global standards and favors an approach of an evolving set of metadata tags for an evolving community of practice. We demonstrate how XML technologies and some minimal technical help for the participating teachers can provide the required foundation for a productive process of integrating E-learning in higher education.

    The purpose of this paper is to discuss the information security assessment criteria used in Russia and compare it with that used in the United States. The computer system security assessment criteria utilized by the State Technical Commission of Russia and similar criteria utilized by the US Department of Defense (TCSEC) are intended for the development and implementation of proven methods for achieving a required level of information security. These criteria are utilized, first and foremost, when conducting certification assessments of general purpose systems. The Russian Federation is creating specialized systems for nuclear material control and accountancy (MC and A) within the framework of the international laboratory-to-laboratory collaboration. Depending on the conditions in which the MC and A system is intended to operate, some of the criteria and the attendant certification requirements may exceed those established or may overlap the requirements established for attestation of such systems. In this regard it is possible to modify the certification and attestation requirements depending on the conditions in which a system will operate in order to achieve the ultimate goal--implementation of the systems in the industry

  4. A Special Issue of the Canadian Journal of Learning and Technology on Knowledge Building

    Directory of Open Access Journals (Sweden)

    Michele Jacobsen

    2010-11-01

    Full Text Available In a pervasive media and technology landscape that is increasingly global, participatory and connected, one in which learners and teachers can increasingly become creators of knowledge rather than mere consumers of prepared messages and ideas, it is vital for the field of educational technology to take stock of the latest research on knowledge building. Marlene Scardamalia and Carl Bereiter, innovative pioneers in the area of Knowledge Building in education, define the construct of Knowledge Building as having several characteristics that distinguish it from constructivist learning in general. Two key characteristics of Knowledge Building are intentionality and community knowledge. Intentionality captures that people engaged in knowledge building know they are doing it and that advances in knowledge are purposeful. Community knowledge captures that while learning is a personal matter, knowledge building is done for the benefit of the community. Scardamalia and Bereiter emphasize that in contrast to being spontaneous, a knowledge building culture requires a supportive learning environment and teacher effort and artistry to create and maintain a community devoted to ideas and to idea improvement. Distinct from improving individual students’ ideas and understanding, the collective work of Knowledge Building is explicitly focused on the creation and improvement of knowledge of value to one’s community – advancement of the knowledge itself.

    2007-08-01

    The vision of the Virtual Observatory (VO) is to make access to astronomical databases as seamless and transparent as browsing the World Wide Web is today. It will federate the data flows from current and future facilities and large scale surveys, and the computational resources and new tools necessary to fully exploit them. This requires both technological developments and an international commitment to standardisation and working culture. Increasingly, it will alter the way that astronomers do science, and the way that future facilities and projects plan for their data management, and the scientific exploitation of their data. It will make an impact on a wide variety of astronomical topics, but especially those using very large databases, and those needing a multiwavelength approach, or more generally the use of multiple archives.

    Campbell, Todd; Oh, Phil Seok

    2015-04-01

    This article provides an introduction for the special issue of the Journal of Science Education and Technology focused on science teaching and learning with models. The article provides initial framing for questions that guided the special issue. Additionally, based on our careful review of each of these articles, some discussion of how selected articles within the issue informed these questions. Specifically, when considering key facets of modeling instruction or design features of modeling curriculum, the studies in the special issue provided insight into productive ways in which teachers engaged students in modeling practices. Further, modeling pedagogies—pedagogies for transforming scientific practices of modeling into students' experience—were reified so that how these pedagogies could be coordinated into classroom instruction was revealed. When characteristic features of students' engagement in modeling were considered, research offered insight into productive model-based learning sequences for K-6 modelers and how students' development of productive epistemologies can evolve differently. Finally, the special issue considered how technology facilitated cognitive processes and/or instructional practices by examining learners' interactions with technology within modeling contexts. In this, instructional sequences using agent-based modeling (ABM) as a central technology are shared. These include the role of ABM in scaling student-modeling experiences beyond individuals to classroom experiences and how ABM can support student investigations of complex phenomenon that is not directly observable, among other affordances. Other articles also investigated some aspects of learners' interactions with technology to inform how technology-enhanced science teaching and learning with models.

    Health technology assessments (HTAs) are increasingly used to inform coverage, access, and utilization of medical technologies including molecular diagnostics (MDx). Although MDx are used to screen patients and inform disease management and treatment decisions, there is no uniform approach to their evaluation by HTA organizations. The International Society for Pharmacoeconomics and Outcomes Research Devices and Diagnostics Special Interest Group reviewed diagnostic-specific HTA programs and identified elements representing common and best practices. MDx-specific HTA programs in Europe, Australia, and North America were characterized by methodology, evaluation framework, and impact. Published MDx HTAs were reviewed, and five representative case studies of test evaluations were developed: United Kingdom (National Institute for Health and Care Excellence's Diagnostics Assessment Programme, epidermal growth factor receptor tyrosine kinase mutation), United States (Palmetto's Molecular Diagnostic Services Program, OncotypeDx prostate cancer test), Germany (Institute for Quality and Efficiency in Healthcare, human papillomavirus testing), Australia (Medical Services Advisory Committee, anaplastic lymphoma kinase testing for non-small cell lung cancer), and Canada (Canadian Agency for Drugs and Technologies in Health, Rapid Response: Non-invasive Prenatal Testing). Overall, the few HTA programs that have MDx-specific methods do not provide clear parameters of acceptability related to clinical and analytic performance, clinical utility, and economic impact. The case studies highlight similarities and differences in evaluation approaches across HTAs in the performance metrics used (analytic and clinical validity, clinical utility), evidence requirements, and how value is measured. Not all HTAs are directly linked to reimbursement outcomes. To improve MDx HTAs, organizations should provide greater transparency, better communication and collaboration between industry and HTA

    Dwyer, J.T.

    1979-01-01

    The prime objective of nutritional surveillance of cancer patients is to set up screening criteria for those who are likely to be at risk of nutrition problems and to further assess those so identified. Interventions to improve nutritional status or comfort are called for. The single most useful item with respect to screening is careful weight measurement at every visit. Subjective reports of appetite and food intake, 24-hour recalls of dietary intake, and therapy being undergone by the patient are also useful. Assessment involves obtaining the 24-hour recall data and in some cases keeping food records, and determining the patients' food likes and dislikes. Taken together, dietary, biochemical, clinical, anthropometric, and patient history data permit us to achieve greater certainty as to the problem. Usually energy intakes are problematic, but other nutrition difficlties may also be present. Intervention with respect to diet may involve therapeutic diets, special nutrition advice, or general advice. Food assistance, help with food managemnt, and general health education may also be necessary. Constant surveillance consisting of short encounters and follow-up are mandatory. Examples of these principles as they apply to head-neck cancers are presented

    The purpose of this laboratory study was to evaluate extrinsic stain removal from teeth by a specially engineered sonic powered toothbrush with unique sensing and control technologies, using the Triple Clean and the Sensitive refill brush heads, in comparison to a manual flat-trim toothbrush. Twelve (12) artificially stained bovine teeth were tested with each product. The percentage of stain removed by each product was calculated by taking the ratio of the amount of stain removed by brushing for 800 strokes to the total amount of stain removed by subsequent application of a dental prophylaxis. The stain was quantified by measuring the light reflected by the stained teeth with a spectrophotometer. Data were reported as L*, lightness of the stain, and as W*, a whiteness index comprising the lightness, hue, and chroma of reflected light. Statistical analyses were performed separately for the AL* and AW* scores. Comparisons of the toothbrushes with respect to baseline-adjusted deltaL* and deltaW* scores were performed using an analysis of covariance (ANCOVA). Post-ANCOVA pair-wise comparisons of the study toothbrushes were performed using Tukey's test for multiple comparisons. All statistical tests of hypotheses were two-sided, and employed a minimum level of significance of 0.05. The percentage of stain removed by the sonic powered toothbrush, using either the Triple Clean brush head or the Sensitive brush head under laboratory test conditions, is superior (p toothbrush when analyzed for both the deltaL* and deltaW* scores. The mean percentage of stain removed was 62.10 for the power toothbrush with the Triple Clean brush head, 49.01 for the power toothbrush with the Sensitive brush head, and 30.56 for the manual flat-trim toothbrush when calculated using deltaL* scores. The mean percentage of stain removed was 59.89 for the power toothbrush with the Triple Clean brush head, 46.83 for the power toothbrush with the Sensitive brush head, and 29.25 for the manual flat

  14. Practical recommendations for the management of cardiovascular risk associated with atherogenic dyslipidemia, with special attention to residual risk. Spanish adaptation of a European Consensus of Experts.

    Science.gov (United States)

    This document has discussed clinical approaches to managing cardiovascular risk in clinical practice, with special focus on residual cardiovascular risk associated with lipid abnormalities, especially atherogenic dyslipidaemia (AD). A simplified definition of AD was proposed to enhance understanding of this condition, its prevalence and its impact on cardiovascular risk. AD can be defined by high fasting triglyceride levels (≥2.3mmol/L / ≥200mg/dL) and low high-density lipoprotein cholesterol (HDL-c) levels (≤1,0 / 40 and ≤1,3mmol/L / 50mg/dL in men and women, respectively) in statin-treated patients at high cardiovascular risk. The use of a single marker for the diagnosis and treatment of AD, such as non-HDL-c, was advocated. Interventions including lifestyle optimization and low density lipoprotein (LDL) lowering therapy with statins (±ezetimibe) are recommended by experts. Treatment of residual AD can be performed with the addition of fenofibrate, since it can improve the complete lipoprotein profile and reduce the risk of cardiovascular events in patients with AD. Others clinical condictions in which fenofibrate may be prescribed include patients with very high TGs (≥5.6mmol/L / 500mg/dL), patients who are intolerant or resistant to statins, and patients with AD and at high cardiovascular risk. The fenofibrate-statin combination was considered by the experts to benefit from a favorable benefit-risk profile. In conclusion, cardiovascular experts adopt a multifaceted approach to the prevention of atherosclerotic cardiovascular disease, with lifestyle optimization, LDL-lowering therapy and treatment of AD with fenofibrate routinely used to help reduce a patient's overall cardiovascular risk.

    As electronic learning (e-learning) becomes increasingly popular in education worldwide, learning technology (LT) has been applied in various learning environments and activities to promote meaningful, efficient, and effective learning. LT has also been adopted by researchers and teacher-practitioners in the field of special education, but as yet little review-based research has been published. This review research thus carefully examined the trends of LT implementations in special education, providing a comprehensive analysis of 26 studies published in indexed journals in the past five years (2008-2012). Two research questions were addressed: (a) What are the major research aims, methodologies, and outcomes in these studies of implementing LT in the field of special education? and (b) What types of LT are mainly used with special education students, and for what kinds of students? Major findings include that examining the learning effectiveness of LT using was the most common research purpose (75%); researchers primarily relied on experimental studies (46%, 12 studies), followed by interviews and questionnaires (19%, 5 studies). Moreover, the most common use of LT was computer-assisted technology (such as web-based mentoring, educational computer games, laptop computers) in special education; studies investigating the use of LT with mentally disabled students were more than those with physically disabled ones. It is expected that the findings of this work and their implications will serve as valuable references with regard to the use of LT with special education students. Copyright © 2013 Elsevier Ltd.

    2011-01-01

    The primary objective of this study was to determine the extent to which international standards on transparency and quality are met by the health technology assessment (HTA) process in Poland. A secondary objective is to describe the outcomes of the HTA process and their associated factors. All published online HTA appraisal and meeting proceedings on pharmaceutical products in 2008 were reviewed using a score card developed from international checklists recommended by INAHTA and ECHTA. The sixty-nine reports reviewed showed that five of nine transparency standards and six of eight quality standards were usually met by the HTA reports. Areas for improvement for transparency include inputs from external stakeholders, availability of English summaries, conclusions, implications of results, and suggested program of action. Areas of improvement for quality include appropriateness of target population and comparator/s, sufficiency of evidence on efficacy and safety, methodological rigor, economic model assumptions, and adaptation to the Polish setting. A consideration of the ethical and social consequences to the healthcare system must also be strengthened. The study demonstrates that the incorporation and implementation of the HTA appraisal process in Poland has been successful. HTA appraisal reports in Poland have considered most of the international standards of transparency and quality. Recommendations for both HTA users and doers are forwarded for the improvement of the HTA process in the Polish setting.

    2016-03-27

    The results of this study suggest that a novel male annihilation technique (specialized pheromone and lure application technology [SPLAT] incorporating cue-lure [CL] plus spinosad) is as effective as industry standard male annihilation controls, and is worth exploring further to manageBactrocera tryoni(Froggatt) populations. Three lures were evaluated in a contact and feeding bioassay and a cage attractancy trial: 1) SPLAT-CL + spinosad; 2) SPLAT-CL without spinosad; and 3) wick-CL + malathion. In a field attraction trial, lures (1) and (3) were evaluated with a third treatment, caneite blocks-CL + malathion. Lures were weathered for 0, 1, 2, 4, or 8 wk, with an additional weathering treatment of 12 wk included in the field trial. In the contact and feeding bioassay, lures with SPLAT-CL + spinosad were >97% effective at 48 h for up to 2 wk weathering; however, wicks-CL + malathion killedB. tryoniwithin 2 h of exposure under all weathering periods. In the cage attractancy trial, SPLAT-CL + spinosad was as effective as, or performed better than, wicks-CL + malathion under all weathering treatments. The field study trap catches were similar for SPLAT-CL + spinosad and blocks-CL + malathion, and both had higher trap catches than wicks-CL + malathion at all weathering periods, except week 12. Overall, SPLAT-CL + spinosad compared favorably with current standard techniques for male annihilation and warrants further research. SPLAT-CL + spinosad may be a reduced-risk alternative for wicks-CL + malathion or blocks-CL + malathion forB. tryoniand other CL-responding fruit flies, such asBactrocera cucurbitaeCoquillett, because it contains a reduced-risk insecticide that poses a lower risk to humans and the environment and does not require labor-intensive handling and placement. © The Authors 2016.

    The presence of ergonomic features can impact the marketplace success of a new product. Metaphase Design Group, Inc., in partnership with the Colgate-Palmolive Company, conducted an ergonomic audit on three electric toothbrushes: a specially engineered sonic powered toothbrush with unique sensing and control technologies, the Sonicare FlexCare, and the Oral-B Smart Series 5000. The ergonomic audit was conducted by Metaphase Design Groups's ergonomic and usability experts. Two experts used the toothbrushes over a one-week period and assessed the performance of each brush against a set of ergonomic principles. The three toothbrushes have some solid ergonomic features. They each have adequate grip zones, provide grip security with elastomeric materials, and provide easy access to the on/off button. The most distinctive feature is the longitudinal shape of the handle of the specially engineered sonic powered toothbrush with unique sensing and control technologies. This handle angles downward at the top end and provides additional advantages through improved grip security and visibility. Yet all three toothbrushes have different opportunities for improvement. The Sonicare Flex Care toothbrush has a cluttered and complicated user interface that is difficult to read. The disadvantages of the Oral-B Smart Series 5000 toothbrush are related to its physical dimensions and audible feedback. The specially engineered sonic powered toothbrush with unique sensing afid control technologies is surprising to use with its changes in speeds, brush movements, and resulting changes in audible feedback.

    2008-01-01

    The President of the Deutsches Atomforum, Dr. Walter Hohlefelder, emphasized in his opening address at the 2008 Annual Nuclear Technology Conference in Hamburg that the German special approach to nuclear power utilization led straight into a dead end of energy policy. ''The outcome is foreseeable: The ambitious German goals of carbon dioxide reduction are missed, the competitiveness of the country is jeopardized, dependency on foreign energy imports rises,'' Dr. Hohlefelder stated. In view of the growing challenges in energy policy Germany had no alternative but to reassess nuclear power. The only outcome of this reappraisal could be extension of the life of nuclear power plants currently in operation. This was necessary also in order to avoid an impending gap in German electricity supply, Dr. Hohlefelder added. He invited all stakeholders to join in an open, unbiased dialog. Dr. Hohlefelder openly criticized the continued ban on research into the development of new reactors. ''A policy of this kind, a policy which bans thinking, is unacceptable in a technology-oriented, industrialized nation such as Germany.'' Nuclear power technology as a high-tech area was a unique achievement which had contributed to the prosperity of the country. The Annual Nuclear Technology Conference, which was held for the 39th time this year, is one of the biggest specialized conferences in the nuclear field with an attendance, this year, of approximately 1300 participants from more than twenty nations.

    2003-01-01

    With the increasing pressure on a more effective and sustainable use of water resources, those water treatment technologies become more and more important which will allow for a recycling of wastewater for agricultural and/or industrial purposes. The so-called advanced oxidation processes (AOP's) belong to these technologies as they offer the potential of a complete conversion of the water pollutants to carbon dioxide, water and mineral salts. Despite the progress that has been achieved in understanding and applying AOP's, the most significant disadvantages of the oxidation technologies are the high investment and operating costs. As these technologies are the high investment and operating costs. As these technologies are based on radical reactions, more effective means of producing radicals and a deeper insight in the reaction pathways will be the key for generating radicals at lower costs as well as choosing the optimum process conditions and defining the applications where AOP's are most competitive. Two national, three international conferences with the publication of their papers in water science and technology (1997 and 2001) as well as the foundation of the IWA Specialist Group on AOP's in 2001 demonstrate the success and the necessity of this conference series. It is designed to bring forward the most recent advances in the fundamentals as well as the development and the application of AOP's especially in the field of water recycling reuse. It will help to disseminate new achievements in these areas and to identify future research and development needs. The increased number of interesting papers submitted will be the basis for a successful, fruitful and hopefully critical conference in Goslar. (orig.)

    The purpose of this study was to examine how objective measures of attention to food/beverage advertising were associated with the unhealthy food/beverage preferences and choices of children and adolescents. A self-report survey and eye-tracking session were completed by 102 youth (mean age=11.6 years; 56.4% were white; 43.1% were female) between April and November 2010. Participants viewed 40 food/beverage advertisements on a computer and their eye movements were recorded. Objective attention measures included total viewing time, fixation length (time spent viewing characters/logos, unhealthy food/beverage items), and fixation count (number of times an individual stops to examine characters/logos, unhealthy food/beverage items). Food/beverage preferences and choices were measured by self-report. The preferences index summed responses to 12 questions measuring snack food and sugar-sweetened beverage preferences and the choices index summed responses to eight questions measuring consumption of snack foods and sugar-sweetened beverages. Regression models examined whether attention to food/beverage advertising was associated with food preferences and choices, controlling for sex, age, and body mass index z score. The length of time and number of times participants looked at unhealthy food and beverage items within advertisements were each significantly associated with unhealthy food/beverage preferences of youth (Pfood/beverage choices. Research with larger samples is needed to more fully understand the role of attention. Future research should also examine the association between attention to advertising and purchase requests, given the important role of parents in the decision-making process surrounding food choice.

    To evaluate the efficacy on plaque and established gingivitis of a new specially engineered sonic powered toothbrush with unique sensing and control technologies as compared to two commercially available power toothbrushes. This examiner-blind, three-treatment, parallel clinical study assessed plaque reduction via the comparison of pre- to postbrushing after a single use, and following four weeks' use measured by the Rustogi Modification of the Modified Navy Plaque Index. This study also assessed gingivitis using the Löe and Silness Gingival Index after four weeks' use. Qualifying adult male and female subjects from the northern New Jersey area reported to the study site after refraining from all oral hygiene procedures for 24 hours, and from eating, drinking, or smoking for four hours. Following an examination for gingivitis and plaque (pre-brushing), they were randomized into three balanced groups, each group using one of the three study toothbrushes in the order specified by a predetermined randomization plan. Subjects were instructed to brush their teeth for two minutes under supervision with their assigned toothbrush according to the manufacturers' instructions and a commercially available toothpaste (Colgate Cavity Protection), after which they were once again evaluated for plaque (post-brushing). Subjects were then dismissed from the study site with the toothpaste and their assigned toothbrush to use at home twice daily for the next four weeks. They again reported to the study site at which time they were evaluated for plaque and gingivitis. One-hundred eighty-four subjects complied with the protocol and completed the clinical study. Relative to the two commercially available toothbrushes, the new specially engineered sonic powered toothbrush with unique sensing and control technologies provided statistically significantly (p toothbrushes, the new sonic powered toothbrush also provided statistically significantly (p 0.05) difference between the two

    Full Text Available Global economy still records a decline in FDI. The main causes are increased economic instability and geopolitical risks. Given the continued negative trend, it is clear that it is necessary to reform the investment policies at the national, regional, bilateral, multilateral and international level, to ensure sustainable economic development. Key elements of the reforms are: to provide instruments to reduce risks, create mechanisms of responsible investment, improve the structural coherence and promote regional investments. Refer to the current dates of the sectors investments (according to the report of UNCTAD from 2015th shows that the services sector recorded double growth compared to the investment in the manufacturing sector in 2012. Also, if we take into consideration the fact that investment in IT sector investment involves three aspects: transactional (minimizing costs, strategic (innovation technologies, achieving competitiveness and information (improving access to information and communications, it may be assumed that the reforms in the investment policies should be directly correlated with investments in information technology.

    Since October 2010, the site of the former Kahl Experimental Nuclear Power Station (VAK) has been returned to the desired green-field condition. A special chapter in the German history of the use of nuclear power, which has played a major role in the technical and economic development of this energy resource, has come to an end after 52 years. When nuclear power pioneer Heinrich Mandel ordered VAK from AEG in 1958, the mood associated with using this source of energy was different from what it is now. Politicians of all parties were euphoric about the use of nuclear power, while power plant operators were more reluctant. Finally, also RWE was convinced and planned the construction of VAK as a joint venture with the Bayernwerk AG (now E.ON) utility in Grosswelzheim, Bavaria. The objective was clear: 'The order was placed so that the atomic power plant to be built could be used to accumulate experience in planning, operation, in capital cost and operating cost.' After a construction period of only 29 months, VAK was commissioned on November 13, 1960 as the first German nuclear power plant. The US-designed boiling water reactor had been designed for a power of 16,000 kilowatt. After synchronization with the power grid, the first electricity produced from nuclear power in Germany was fed into the interconnected grid system on June 17, 1961. In its 25 years of operation, VAK proved to be a valuable experimental facility. The plant was decommissioned on November 25, 1985 as planned. In order to maintain its experimental character also beyond the operating phase, the operators had agreed from the beginning to demolish VAK completely to green-field conditions immediately after the end of operations. This became official on May 17, 2010, when the plant was released from the scope of the Atomic Energy Act and was granted a permit for demolition under conventional building law. (orig.)

    Telehealth programs for heart failure have been studied using a variety of techniques. Because currently a majority of the elderly are nonusers of computers and Internet, we developed a home telehealth system based on digital pen technology. Fourteen patients (mean age, 84 years [median, 83 years]) with severe heart failure participated in a 13-month pilot study in specialized homecare. Participants communicated patient-reported outcome measures daily using the digital pen and health diary forms, submitting a total of 3 520 reports. The reports generated a total of 632 notifications when reports indicated worsening health. Healthcare professionals reviewed reports frequently, more than 4700 times throughout the study, and acted on the information provided. Patients answered questionnaires and were observed in their home environment when using the system. Results showed that the technology was accepted by participants: patients experienced an improved contact with clinicians; they felt more compliant with healthcare professionals' advice, and they felt more secure and more involved in their own care. Via the system, the healthcare professionals detected heart failure-related deteriorations at an earlier stage, and as a consequence, none of the patients were admitted into hospital care during the study.

  4. Visuospatial selective attention in chickens.

    Voluntary control of attention promotes intelligent, adaptive behaviors by enabling the selective processing of information that is most relevant for making decisions. Despite extensive research on attention in primates, the capacity for selective attention in nonprimate species has never been quantified. Here we demonstrate selective attention in chickens by applying protocols that have been used to characterize visual spatial attention in primates. Chickens were trained to localize and report the vertical position of a target in the presence of task-relevant distracters. A spatial cue, the location of which varied across individual trials, indicated the horizontal, but not vertical, position of the upcoming target. Spatial cueing improved localization performance: accuracy (d') increased and reaction times decreased in a space-specific manner. Distracters severely impaired perceptual performance, and this impairment was greatly reduced by spatial cueing. Signal detection analysis with an "indecision" model demonstrated that spatial cueing significantly increased choice certainty in localizing targets. By contrast, error-aversion certainty (certainty of not making an error) remained essentially constant across cueing protocols, target contrasts, and individuals. The results show that chickens shift spatial attention rapidly and dynamically, following principles of stimulus selection that closely parallel those documented in primates. The findings suggest that the mechanisms that control attention have been conserved through evolution, and establish chickens--a highly visual species that is easily trained and amenable to cutting-edge experimental technologies--as an attractive model for linking behavior to neural mechanisms of selective attention.

  5. Recipe and technology development for minced canned products of special purpose based on the underutilized north region fishery object (thorny skate

    Directory of Open Access Journals (Sweden)

    Raibulov S. P.

    2016-09-01

    Full Text Available The paper presents the results of justifying the use of thorny skate in the technology of minced meat canned products of special purpose. The key criterion determined the specialized purpose of canned food is the high content of physiologically functional food ingredient of chondroitin sulfate in the cartilage of thorny skate wings. The high content of chondroitin sulfate in raw materials ensures that the content of the physiologically functional ingredient in the finished canned food will be at the level from 220 to 250 mg per 100 g of product. The method of IR blanching is presented for removing urea from the thorny skate muscle tissue. To confirm the efficiency of the developed method of urea removal, it has been proposed to use a modified photocolorimetric method for determination of mass fractions of urea in feed flour according to the governmental standard GOST R 50032–92 "Feed flour made of fish, marine mammals, crustaceans and invertebrates. Methods of determining the mass fraction of urea and calculation of the crude protein with a given mass fraction of carbamide". With the help of this technique, the efficiency of urea removal from the thorny skate tissue by the proposed method has been determined. The residual urea content in the meat of thorny skate after IR blanching is 0.76 %, which is two times lesser than border value of sensitivity of the person (approximated as 1.2 %. The paper presents the materials of experimental substantiation of optimum formulation of new canned meat based on the method of fuzzy modeling. The ratio of the main components of the meatballs recipe (thorny skate and Atlantic cod close to the optimum is 48 % by weight of meat for each component separately.

    2011-01-01

    Diagnosis of attention deficit/hyperactivity disorder (ADHD) in children is not straightforward and misdiagnosis may occur, which leads to the possibility of errors in treatment, with numerous possible side effects that could be especially damaging in view of the age of the population. For this reason, a tool that is easy to use, fast, and cost-effective, which provides an addition to conventional diagnosis and treatment monitoring of ADHD children, is needed. In this study, electro interstitial scans (EIS) were used to perform bioimpedance measurements. The results of conductivity measurements taken using forehead electrodes in a group of children conventionally diagnosed with ADHD and in a control group not showing any symptoms of ADHD were compared. Sixty children without any ADHD symptoms (group 1) and 52 children diagnosed with ADHD following psychiatric examination (group 2) underwent an examination with the EIS system. Statistical analysis was performed to compare the conductivity measurements at the level of the forehead electrodes, using independent t-tests and a receiver-operating characteristic curve (ROC) to determine the specificity and sensitivity of the test. The mean of the conductivity measurements of two pathways between the forehead electrodes (from left forehead to right forehead and from right forehead to left forehead) in the ADHD group was 33.11 micro Siemens (mS) (range 2-113 mS). This was significantly higher (P ADHD children. It could also assist in treatment monitoring, and allow for earlier intervention.

    While much literature has been devoted to theoretical explanations of the learning processes of older adults and to the methods of teaching best utilized in older populations, less has focused on the education of older adults who reside in assisted and independent living communities (AICs), especially with regards to information and communication technology (ICT) education. The purpose of this study is to determine whether participants' attitudes and views towards computers and the Internet are affected as a result of participating in an eight-week training program designed to enhance computer and Internet use among older adults in such communities. Specifically, we examine if ICT education specially designed for AIC residents results in more positive attitudes towards ICTs and a perceived decrease in factors that may limit or prevent computer and Internet use. We discuss the implications of these results for enhancing the quality of life for older adults in AICs and make recommendations for those seeking to decrease digital inequality among older adults in these communities through their own ICT classes.

    1991-01-01

    Attention Deficit Disorder (ADD) is a behavioral disorder characterized by the inability to sustain attention long enough to perform activities such as schoolwork or organized play. Treatments for this disorder include medication and brainwave biofeedback training. Brainwave biofeedback training systems feed back information to the trainee showing him how well he is producing the brainwave pattern that indicates attention. The Extended Attention Span Training (EAST) system takes the concept a step further by making a video game more difficult as the player's brainwaves indicate that attention is waning. The trainee can succeed at the game only by maintaining an adequate level of attention. The EAST system is a modification of a biocybernetic system that is currently being used to assess the extent to which automated flight management systems maintain pilot engagement. This biocybernetic system is a product of a program aimed at developing methods to evaluate automated flight deck designs for compatibility with human capabilities. The EAST technology can make a contribution in the fields of medical neuropsychology and neurology, where the emphasis is on cautious, conservative treatment of youngsters with attention disorders.

    Highlights: • Broad summary of phase change materials based cooling for photovoltaic modules. • Compendium on phase change materials that are mostly used in photovoltaic systems. • Extension of heat availability period by 75–100% with phase change material. • Heat storage potential improves by 33–50% more with phase change material. • Future trend and move in photovoltaic thermal research. - Abstract: This communication lays out an appraisal on the recent works of phase change materials based thermal management techniques for photovoltaic systems with special focus on the so called photovoltaic thermal-phase change material system. Attempt has also been made to draw wide-ranging classification of both photovoltaic and photovoltaic thermal systems and their conventional cooling or heat harvesting methods developed so far so that feasible phase change materials application area in these systems can be pointed out. In addition, a brief literature on phase change materials with particular focus on their solar application has also been presented. Overview of the researches and studies establish that using phase change materials for photovoltaic thermal control is technically viable if some issues like thermal conductivity or phase stability are properly addressed. The photovoltaic thermal-phase change material systems are found to offer 33% (maximum 50%) more heat storage potential than the conventional photovoltaic-thermal water system and that with 75–100% extended heat availability period and around 9% escalation in output. Reduction in temperature attained with photovoltaic thermal-phase change material system is better than that with regular photovoltaic-thermal water system, too.

    2014-04-01

    As the body of scientific knowledge in a discipline increases, there is pressure for specialization. Fields spawn subfields that then become entities in themselves that promote further specialization. The process by which scientists join specialized groups has remarkable similarities to the guild system of the middle ages. The advantages of specialization of science include efficiency, the establishment of normative standards, and the potential for greater rigor in experimental research. However, specialization also carries risks of monopoly, monotony, and isolation. The current tendency to judge scientific work by the impact factor of the journal in which it is published may have roots in overspecialization, as scientists are less able to critically evaluate work outside their field than before. Scientists in particular define themselves through group identity and adopt practices that conform to the expectations and dynamics of such groups. As part of our continuing analysis of issues confronting contemporary science, we analyze the emergence and consequences of specialization in science, with a particular emphasis on microbiology, a field highly vulnerable to balkanization along microbial phylogenetic boundaries, and suggest that specialization carries significant costs. We propose measures to mitigate the detrimental effects of scientific specialism.

    A special manifold is an allowed target manifold for the vector multiplets of D=4, N=2 supergravity. These manifolds are of interest for string theory because the moduli spaces of Calabi-Yau threefolds and c=9, (2,2) conformal field theories are special. Previous work has given a local, coordinate-dependent characterization of special geometry. A global description of special geometries is given herein, and their properties are studied. A special manifold M of complex dimension n is characterized by the existence of a holomorphic Sp(2n+2,R)xGL(1,C) vector bundle over M with a nowhere-vanishing holomorphic section Ω. The Kaehler potential on M is the logarithm of the Sp(2n+2,R) invariant norm of Ω. (orig.)

    In the new digital age, information is available in large quantities. Since information consumes primarily the attention of its recipients, the scarcity of attention is becoming the main limiting factor. In this study, we investigate the impact of advertisement pressure on a cultural market where consumers have a limited attention capacity. A model of competition for attention is developed and investigated analytically and by simulation. Advertisement is found to be much more effective when the attention capacity of agents is extremely scarce. We have observed that the market share of the advertised item improves if dummy items are introduced to the market while the strength of the advertisement is kept constant.

A huge amount of research has been produced on this subject in the last half century, especially on attention in the visual modality, but a general explanation has remained elusive. Many still view attention...... research as a field that is fundamentally fragmented. This book takes a different perspective and presents a unified theory of visual attention: the TVA model. The TVA model explains the many aspects of visual attention by just two mechanisms for selection of information: filtering and pigeonholing....... These mechanisms are described in a set of simple equations, which allow TVA to mathematically model a large number of classical results in the attention literature. The theory explains psychological and neuroscientific findings by the same equations; TVA is a complete theory of visual attention, linking mind...

    2001-01-01

    Concrete is the most convenient material when large-scale radiation protection is needed. Thus, special concretes for nuclear purposes are used in various facilities like reactors, reprocessing centers, storage sites, accelerators, hospitals with nuclear medicine equipment, food ionization centers etc.. The recent advances made in civil engineering for the improvement of concrete durability and compactness are for a large part transposable to protection concretes. This article presents the basic knowledge about protection concretes with the associated typological and technological aspects. A large part is devoted to the intrinsic properties of concretes and to their behaviour in irradiation and temperature conditions: 1 - definition and field of application of special protective concretes; 2 - evolution of concepts and technologies (durability of structures, techniques of formulation, new additives, market evolution); 3 - design of protective structures (preliminary study, radiation characteristics, thermal constraints, damping and dimensioning, mechanical criteria); 4 - formulation of special concretes (general principles, granulates, hydraulic binders, pulverulent additives, water/cement ratio, reference composition of some special concretes); 5 - properties of special concretes (damping and thermo-mechanical properties); 6 - induced-irradiation and temperature phenomena (activation, radiolysis, mineralogical transformations, drying, shrinking, creep, corrosion of reinforcement).

I argue that the progress made is laudable but caution that it may vanish rapidly if, due to a number of factors and events, including the need to ameliorate the consequences of the global financial crisis, attention is redirected at resuming a nation building project centred on land development and automobility. This paper uses a fourfold-criterion to analyse the new specialization in non-motorized transportation planning and to discuss the dilemma of technology transfer among communities and countries.

  20. Is memory for music special?

    Science.gov (United States)

    Schulkind, Matthew D

    2009-07-01

    Although psychologists since Hermann Ebbinghaus have studied memory, research in this area has focused on visual and verbal stimuli with little attention paid to music. This bias is surprising because of the ubiquity of music in human cultures across history as well as current cultural beliefs that memory for music is "special." This paper examines the question of whether memory for music is special by addressing two related questions: First, do cultural beliefs about the mnemonic power of music stand up to empirical test? Second, can theories designed to explain memory for non-musical stimuli be applied to musical stimuli? A review of the literature suggests that music is special in some circumstances but not others and that some theories designed to explain cognitive processing of linguistic stimuli apply reasonably well to musical stimuli. Thus, although the question of whether memory for music is special remains open, the unique structure of musical stimuli strongly suggests that memory for music is indeed special.

  1. The neuroanatomy of attention.

    Science.gov (United States)

    Filley, Christopher M

    2002-05-01

    Attention is a complex neurobehavioral domain that is essential for all higher functions. Large areas of the brain are devoted to attention, reflecting its importance in the entire range of mental operations. Currently, two major distributed neural networks are recognized as mediating complementary aspects of attentional function. One is a diffuse system that distributes attention globally. This attentional system is subserved by a widespread network of thalamic and bihemispheric structures in which the frontal lobes are particularly important. The second network, a focal system that distributes attention to salient aspects of spatial experience, is lateralized to frontal and parietal regions of the right hemisphere. Both attentional networks are comprised of cortical and subcortical gray matter structures, as well as connecting white matter tracts that integrate these regions into functional ensembles. Neurological disorders frequently produce dramatic syndromes reflecting dysfunction of these networks. Among these syndromes are the acute confusional state, which results from disturbance of the diffuse system, and left neglect, which follows disruption of the right hemisphere system. The neuroanatomy of attention is crucial for understanding important neurobehavioral syndromes and their treatment.

Four decision theories are examined: rational models, bounded rationality, evidence accumulation, and parallel constraint...... satisfaction models. Although most theories were confirmed with regard to certain predictions, none of the theories adequately accounted for the role of attention during decision making. Several observations emerged concerning the drivers and down-stream effects of attention on choice, suggesting...... that attention processes plays an active role in constructing decisions. So far, decision theories have largely ignored the constructive role of attention by assuming that it is entirely determined by heuristics, or that it consists of stochastic information sampling.

  4. Concerning remorse: with special attention to its defensive function.

    Science.gov (United States)

    Hoyt, M F

    1983-07-01

    Remorse involves a sense of guilty and shameful condemnation having sources in both the Self and Other. In addition to providing punishment for real or imagined wrongdoing, remorse may function to preserve a relationship with the harmed Other, who is kept alive and intact as an internalized judge. As painful as the feelings of remorse are, they may be sought or clung to as a defense against having to give up the Other, who, via incorporative processes, may be unconsciously experienced as part of the self. Painful memories and affects may serve to ward off the feelings of abject emptiness that would otherwise be experienced, especially with persons whose sense of self is highly dependent on a stable relationship with an Other. After a brief review of the etymology of the term "remorse" ("to bite again") and some of its cultural manifestations, the defensive, relationship-maintaining function of remorse was further illustrated with a case vignette.

    Full Text Available The enteric heath of growing poultry is imperative to success of the production. The basic role of poultry production is turning feed stuffs into meat. Any changes in this turning process, due to mechanical, chemical or biological disturbance of digestive system (enteric disorders is mostly accompanied with high economic losses due to poor performance, increased mortality rates and increased medication costs. The severity of clinical signs and course of the disorders are influenced several factors such as management, nutrition and the involved agent(s. Several pathogens (viruses, bacteria and parasites are incriminated as possible cause of enteric disorders either alone (mono-causal, in synergy with other micro-organisms (multi-causal, or with non-infectious causes such as feed and /or management related factors. In addition, excessive levels of mycotoxins and biogenic amines in feed lead to enteric disorders. Also factors such as high stocking density, poor litter conditions, poor hygiene and high ammonia level and other stressful situation may reduce the resistance of the birds and increases their susceptibility to infections. Under field conditions, however, under filed conditions it is difficult to determine whether the true cause of enteric disorders, is of infectious or non-infectious origin. In recent years and since the ban of use of antimicrobial growth promoters in several countries the incidence of intestinal disorders especially those caused by clostridial infection was drastically increased. The present review described in general the several factors involved in enteric disorders and summarized the available literatures about Clostridium perfringens infection in poultry.

    Hemophilia is a rare disorder, whereas recurrent bleedings in the joint can result in osteoarthropathy. Radiological changes consist of osteoporosis, enlargement of the epiphyses, irregularity of the subchondral bone surface, narrowing of the joint space, cysts, erosions, joint incongruence and joint deformity. The earlier and the more frequently bleedings have occurred which have not been treated adequately, the more of the changes mentioned above are present. In children, osteoarthropathy of the elbow is present in only about 50% of cases, and in the remaining cases the degree is mostly minimal or moderate. Differential diagnosis consists of juvenile rheumatoid arthritis in children, and rheumatoid arthritis and osteoarthritis in adults. (orig.) [de

    Deficits of attention, emotion, and cognition occur in individuals with alcohol abuse and addiction. This review elucidates the concepts of attention, emotion, and cognition and references research on the underlying neural networks and their compromise in alcohol use disorder. Neuroimaging research on adolescents with family history of alcoholism contributes to the understanding of pre-existing brain structural conditions and characterization of cognition and attention processes in high-risk individuals. Attention and cognition interact with other brain functions, including perceptual selection, salience, emotion, reward, and memory, through interconnected neural networks. Recent research reports compromised microstructural and functional network connectivity in alcoholism, which can have an effect on the dynamic tuning between brain systems, e.g., the frontally based executive control system, the limbic emotion system, and the midbrain-striatal reward system, thereby impeding cognitive flexibility and behavioral adaptation to changing environments. Finally, we introduce concepts of functional compensation, the capacity to generate attentional resources for performance enhancement, and brain structure recovery with abstinence. An understanding of the neural mechanisms of attention, emotion, and cognition will likely provide the basis for better treatment strategies for developing skills that enhance alcoholism therapy adherence and quality of life, and reduce the propensity for relapse. © 2014 Elsevier B.V.

    2014-09-01

    Building on previous work on the role of attention deficits associated with the regulation of executive control in psychiatric disorders, we examine whether these attention deficits are related to an interpersonal disturbance, the experience of divorce. Attentional capacities of 95 randomly selected couples from the general population were measured with a well-established task, the Attentional Network Task, which assesses the efficiency of 3 attention networks (that is, alerting, orienting, and executive control). Among the 190 participants, 32 had experienced a divorce in the past. ANCOVAs were used to compare divorced people in marital or cohabiting unions with people in first unions in their performance on this purely cognitive task. Our findings indicate that divorced people who are currently living in a cohabiting relationship show significantly lower executive control than other adults living as couples, after controlling for sex, age, income, and education. This subgroup of divorced people not only exhibit greater difficulty in responding to some stimuli while ignoring irrelevant ones but also manifest cognitive deficits in conflict resolution. This study highlights the links between attention and the long-term maintenance of intimate relationships. Our results may have important implications for the identification of people at risk for divorce.

    While CON–DMN anti-correlation is associated with improved attention in ADHD, other circuitry supports improved attention in TD children. Greater CON–DMN anti-correlation supported better attentional control in children with ADHD, but worse attentional control in TD children. On the other hand, greater DMN–occipital anti-correlation supported better attentional control in TD children.

    Commodari, Elena; Guarnera, Maria

    2005-04-01

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

  20. Attention in Urban Foraging

    Directory of Open Access Journals (Sweden)

    Malcolm McCullough

    2013-05-01

    Full Text Available This position paper argues how there has to be much more to smart city learning than just wayshowing, and something better as augmented reality than covering the world with instructions. Attention has become something for many people to know better in an age of information superabundance. Embodied cognition explains how the work-ings of attention are not solely a foreground task, as if attention is something to pay. As digital media appear in ever more formats and contexts, their hybrids with physical form increasing influence how habitual engagement with persistent situations creates learning. Ambient information can just add to the distraction by multitasking, or it can support more favorable processes of shifting among different kinds of information with a particular intent. As one word for this latter process, foraging deserves more consideration in smart city learning

    Larsson Lund, Maria; Nygård, Louise; Kottorp, Anders

    2014-01-01

    The aim was to explore the relationships between difficulties in the use of everyday technology (ET) and the ability to perform activities of daily life (ADL) in the home and in society and in the workplace in people with acquired brain injury (ABI). The investigation comprises an explorative cross-sectional study of 74 people with ABI. The short version of the Everyday Technology Use Questionnaire (S-ETUQ) and a revised version of the ADL taxonomy were used to evaluate the participants. Rasch-generated person ability measures of ET use and ADL were used in correlation analyses, in group comparisons by ANOVA and in logistic regressions. Difficulty in the use of ET was significantly correlated with ADL limitations. People who worked full- or part-time had significantly higher ability to use ET than those with some type of full-time, long-term sickness compensation. The ability to use ET, ADL ability and age were significantly related to return to work. The ability to use ET is related to all areas of everyday functioning in people with ABI. Therefore, a patient's ability to use ET needs to be considered in rehabilitation strategies following an ABI to enhance the patient's performance of activities in the home and in society and to support his or her likelihood of returning to work.

  12. Genre, technology and embodied interaction: The evolution of digital game genres and motion gaming

    Directory of Open Access Journals (Sweden)

    Andreas Gregersen

    2011-11-01

    Full Text Available Technology has been given relatively little attention in genre theory, but this article argues that material technologies can be important components in genre development. The argument is based on a historically informed analysis of digital games, with special attention paid to home console video games and recent genre developments within this domain commonly referred to as motion gaming. The main point is that digital game genres imply structured embodied activity. A constitutive element of digital game mediation is a control interface geared to player embodiment, and I propose the concept of ‘interaction modes’ to describe the coupling of technology and player embodiment and show how this can be integrated with genre theory. The resulting framework allows for increased attention to continuity and change in game and communication genres, material and digital technologies, and the related interaction modes.

    2018-05-01

    In this work, we aim to predict human eye fixation with view-free scenes based on an end-to-end deep learning architecture. Although Convolutional Neural Networks (CNNs) have made substantial improvement on human attention prediction, it is still needed to improve CNN based attention models by efficiently leveraging multi-scale features. Our visual attention network is proposed to capture hierarchical saliency information from deep, coarse layers with global saliency information to shallow, fine layers with local saliency response. Our model is based on a skip-layer network structure, which predicts human attention from multiple convolutional layers with various reception fields. Final saliency prediction is achieved via the cooperation of those global and local predictions. Our model is learned in a deep supervision manner, where supervision is directly fed into multi-level layers, instead of previous approaches of providing supervision only at the output layer and propagating this supervision back to earlier layers. Our model thus incorporates multi-level saliency predictions within a single network, which significantly decreases the redundancy of previous approaches of learning multiple network streams with different input scales. Extensive experimental analysis on various challenging benchmark datasets demonstrate our method yields state-of-the-art performance with competitive inference time.

    2017-01-01

    Nowadays, the pollution of water has become worse in many parts of the world, which causes a severe shortage of clean water and attracts widespread attention worldwide. Bioinspired from nature, i.e. spider silk, cactus, Namib desert beetle, Nepenthes alata, special wettability surfaces have attracted great interest from fundamental research to water-harvesting applications. Here, recently published literature about creatures possessing water-harvesting ability are reviewed, with a focus on the corresponding water-harvesting mechanisms of creatures in dry or arid regions, consisting of the theory of wetting and transporting. Then a detailed account of the innovative fabrication technologies and bionic water-harvesting materials with special wetting are summarized, i.e. bio-inspired artificial spider silk, bio-inspired artificial cactus-like structures, and bio-inspired artificial Namib desert beetle-like surfaces. Special attentions are paid to the discussion of the advantages and disadvantages of the technologies, as well as factors that affect the amount of water-harvesting. Finally, conclusions, future outlooks and the current challenges for future development of the water-harvesting technology are presented and discussed. © 2016 WILEY-VCH Verlag GmbH & Co.

    2013-01-01

    This book offers an essential bridge between college-level introductions and advanced graduate-level books on special relativity. It begins at an elementary level, presenting and discussing the basic concepts normally covered in college-level works, including the Lorentz transformation. Subsequent chapters introduce the four-dimensional worldview implied by the Lorentz transformations, mixing time and space coordinates, before continuing on to the formalism of tensors, a topic usually avoided in lower-level courses. The book’s second half addresses a number of essential points, including the concept of causality; the equivalence between mass and energy, including applications; relativistic optics; and measurements and matter in Minkowski spacetime. The closing chapters focus on the energy-momentum tensor of a continuous distribution of mass-energy and its covariant conservation; angular momentum; a discussion of the scalar field of perfect fluids and the Maxwell field; and general coordinates.

    on competition, the challenge is to know how to identify and prioritize the development tasks. If possible, an effective strategy can be defined. This article suggests a framework for identification and analysis of a product portfolio, with special emphasis on identifying critical technology building blocks......In order to have a better base for decisions, R&D managers need to know what the critical areas of development are in relation to the technologies they develop, mature, and include in the portfolio. As most of the technologies in a company have the potential to have a significant impact...... based on reasoning about product properties. Current approaches lack such views, and by focusing on these, potential make or break decisions are better supported. It is suggested to adopt the proposed framework to clarify where in the portfolio the technology needs critical attention for the next...

    Solar power is growing much faster than most policymakers and analysts realise. As costs come down and feed-in tariffs go up across Europe, a number of countries have started in pursuit of market leader Germany. But in Germany criticism is growing of the multi-billion-euro support schemes that keep the solar industry booming. In this section of the magazine several articles are dedicated to developments in solar energy in Europe. The first article is an overview story on the strong growing global market for solar cells, mainly thanks to subsidy schemes. The second article is on the position of foreign companies in the solar market in Italy. Article number three is dedicated to the conditions for solar technology companies to establish themselves in the German state of Saxony. Also the fifth article deals with the development of solar cells in Saxony: scientists, plant manufacturers and module producers in Saxony are working on new technologies that can be used to produce solar electricity cost-effectively. The goal is to bring the price down to match that of conventionally generated electricity within the next few years. The sixth article deals with the the solar power market in Belgium, which may be overheated or 'oversubsidized'. Article seven is on France, which used to be a pioneer in solar technology, but now produces only a fraction of the solar output of market leader Germany. However, new attractive feed-in-tariffs are changing the solar landscape drastically

  10. Characterization of various Si-photodiode junction combinations and layout specialities in 0.18µm CMOS and HV-CMOS technologies

    With the ongoing miniaturization of CMOS technologies the need for integrated optical sensors on smaller scale CMOS nodes arises. In this paper we report on the development and implementation of different optical sensor concepts in high performance 0.18µm CMOS and high voltage (HV) CMOS technologies on three different substrate materials. The integration process is such that complete modularity of the CMOS processes remains untouched and no additional masks or ion implantation steps are necessary for the sensor integration. The investigated processes support 1.8V and 3V standard CMOS functionality as well as HV transistors capable of operating voltages of 20V and 50V. These processes intrinsically offer a wide variety of junction combinations, which can be exploited for optical sensing purposes. The availability of junction depths from submicron to several microns enables the selection of spectral range from blue to infrared wavelengths. By appropriate layout the contributions of photo-generated carriers outside the target spectral range can be kept to a minimum. Furthermore by making use of other features intrinsically available in 0.18µm CMOS and HV-CMOS processes dark current rates of optoelectronic devices can be minimized. We present TCAD simulations as well as spectral responsivity, dark current and capacitance data measured for various photodiode layouts and the influence of different EPI and Bulk substrate materials thereon. We show examples of spectral responsivity of junction combinations optimized for peak sensitivity in the ranges of 400-500nm, 550-650nm and 700-900nm. Appropriate junction combination enables good spectral resolution for colour sensing applications even without any additional filter implementation. We also show that by appropriate use of shallow trenches dark current values of photodiodes can further be reduced.

  17. Attention-Seeking Displays.

    Directory of Open Access Journals (Sweden)

    Szabolcs Számadó

    Full Text Available Animal communication abounds with extravagant displays. These signals are usually interpreted as costly signals of quality. However, there is another important function for these signals: to call the attention of the receiver to the signaller. While there is abundant empirical evidence to show the importance of this stage, it is not yet incorporated into standard signalling theory. Here I investigate a general model of signalling - based on a basic action-response game - that incorporates this searching stage. I show that giving attention-seeking displays and searching for them can be an ESS. This is a very general result and holds regardless whether only the high quality signallers or both high and low types give them. These signals need not be costly at the equilibrium and they need not be honest signals of any quality, as their function is not to signal quality but simply to call the attention of the potential receivers. These kind of displays are probably more common than their current weight in the literature would suggest.

    2013-06-01

    Full Text Available ABSTRACTInnovationcan be considered to be a complex phenomenon including technical andnon-technical aspects. A remarkable increase in the interdisciplinary attention devoted to innovation has been noticed over the recent decades but the formal technological and economic aspects of innovation have received much more attention and have been taken into account in a far greater number of analyses, despite the great importance of the non-technological dimension of innovation.This paper attempts a review on the important subject of non-technological innovation. The main ideas on the non-technological dimension of innovation research will be highlighted, followed by an attempt to integrate diverse and disparate perspectives on the subject, to present evidence on possible generalizations and to discuss eventual research gaps and opportunities for further studies. The relationship between technological and non-technological innovation is complex and not fully understood. Among several aspects that will be covered in this paper, two specific ones will receive special attention in this brief analysis: the evidence on the impacts of non-technological innovation, and the measurements efforts that have been made concerning this phenomenon.

  1. Special Memories at INIS

    2015-01-01

    INIS: a worldwide hub where nuclear information is preserved, validated, and made universally available. Within this special edition of the Newsletter, celebrating the 45th birthday of INIS, you will probably read this definition, and many more, of the International Nuclear Information System. However, INIS has some special aspects, not immediately visible to those who interact with the System and the INIS Secretariat, which make it unique in the scientific environment. In this article, I will try to share my experience with INIS and the memories that have stayed with me, even after my departure. I joined INIS in 2006 as an IT Systems Engineer. I must say that I found a very complex IT infrastructure with over 20 servers and several software applications which, given the small size of the INIS Unit, clearly reflected the multitude of activities INIS was (and still is) involved in. From the start, I felt that INIS was perceived in a different way by other people involved with Information Technology. In fact, since its birth in 1970, INIS has proven to be extremely innovative and open to embracing new technologies, compared with other parts of the Agency. For example, Livelink was proposed and installed for the first time by the INIS Unit before becoming the IAEA standard tool for enterprise document management, and presently, is uniquely and sharply customized to fulfill INIS’ critical weekly task of processing thousands of bibliographic and full text records

    Technological cycles have been characterized as the basis of long and continuous periods economic growth through sustained changes in total factor productivity. While this hypothesis is in part consistent with several theories of growth, the sheer magnitude and length of the economic revolutions experienced by humankind seems to indicate surmise that more attention should be given to the origin of major technological and economic changes, with reference to one crucial question: role of production and use of energy in economic development.

  3. Attention: the claustrum.

    Goll, Yael; Atlan, Gal; Citri, Ami

    2015-08-01

    The claustrum is a mysterious thin sheet of neurons lying between the insular cortex and the striatum. It is reciprocally connected with almost all cortical areas, including motor, somatosensory, visual, auditory, limbic, associative, and prefrontal cortices. In addition, it receives neuromodulatory input from subcortical structures. A decade ago, Sir Francis Crick and Christof Koch published an influential review proposing the claustrum as the 'seat of consciousness', spurring a revival of interest in the claustrum. We review the literature on the claustrum, emphasizing recent discoveries, and develop a detailed hypothesis describing a role for the claustrum in the segregation of attention.

  5. Attention to memory: orienting attention to sound object representations.

    Backer, Kristina C; Alain, Claude

    2014-01-01

    Despite a growing acceptance that attention and memory interact, and that attention can be focused on an active internal mental representation (i.e., reflective attention), there has been a paucity of work focusing on reflective attention to 'sound objects' (i.e., mental representations of actual sound sources in the environment). Further research on the dynamic interactions between auditory attention and memory, as well as its degree of neuroplasticity, is important for understanding how sound objects are represented, maintained, and accessed in the brain. This knowledge can then guide the development of training programs to help individuals with attention and memory problems. This review article focuses on attention to memory with an emphasis on behavioral and neuroimaging studies that have begun to explore the mechanisms that mediate reflective attentional orienting in vision and more recently, in audition. Reflective attention refers to situations in which attention is oriented toward internal representations rather than focused on external stimuli. We propose four general principles underlying attention to short-term memory. Furthermore, we suggest that mechanisms involved in orienting attention to visual object representations may also apply for orienting attention to sound object representations.

    It's been 12 years since the Journal published its last special themed issue (see Winter 1998, volume 27, no. 1), focused on the World Congress held in Telford, UK, in July 1997. Since that time, there have been a number of subjects that probably warranted special attention, but were not addressed. For that, you can blame one of the Editors of this special issue, who served as Journal Editor during that 10-year period. The topic of interprofessional education (IPE) and care (IPC) is one such theme that warrants our attention at this time. Interprofessional approaches by now have received not only increased attention in the United States, but attention from across the globe. This makes the task of putting together this issue both easy but, at the same time, a bit daunting. Easy in the sense that there is no lack of reports, programs, and efforts at implementing both IPE and IPC from which to choose. Daunting for the same reason: Which are the ones that deserve special attention? What major initiative have we missed?

    2014-01-01

    Over the last two decades, there have been numerous technical and methodological advances available to clinicians and researchers to better understand attention deficit hyperactivity disorder (ADHD) and its etiology. Despite the growing body of literature investigating the disorder’s pathophysiology, ADHD remains a complex psychiatric disorder to characterize. This chapter will briefly review the literature on ADHD, with a focus on its history, the current genetic insights, neurophysiologic theories, and the use of neuroimaging to further understand the etiology. We address some of the major concerns that remain unclear about ADHD, including subtype instability, heterogeneity, and the underlying neural correlates that define the disorder. We highlight that the field of ADHD is rapidly evolving; the descriptions provided here will hopefully provide a sturdy foundation for which to build and improve our understanding of the disorder.

  17. Chewing and Attention: A Positive Effect on Sustained Attention

    Directory of Open Access Journals (Sweden)

    Yoshiyuki Hirano

    2015-01-01

    Full Text Available Chewing is crushing food not only to aid swallowing and digestion, but also to help stress relief and regulate cognitive function, especially in attention. It is well known that chewing gum is used for sleepiness prevention during work, learning, and driving, suggesting a link between chewing and sustained attention. We hypothesized that chewing elevates attention and/or alertness, leading to improvements in cognitive performance. We carried out a systematic review of the PubMed database. We inspected the attributes of effects on attention in studies investigating the effects of chewing on attention or alertness conducted with pre-post design in healthy subjects, except elderly. We identified 151 references, 22 of which were included: 14 (64% showed positive attributes of effects on attention, 1 (5% showed negative attributes of effects on attention, 5 (23% showed both positive and negative attributes of effects on attention, and 2 (9% showed no significant attributes of effects on attention. Thus, positive attributes of effects of chewing on attention, especially on sustained attention, were shown in over half of the reports. These effects also appeared with improvement in mood and stress relief and were influenced by time-on-task effect. Further studies are needed, but chewing could be useful for modifying cognitive function.

  18. Social Image Captioning: Exploring Visual Attention and User Attention

    Directory of Open Access Journals (Sweden)

    Leiquan Wang

    2018-02-01

    Full Text Available Image captioning with a natural language has been an emerging trend. However, the social image, associated with a set of user-contributed tags, has been rarely investigated for a similar task. The user-contributed tags, which could reflect the user attention, have been neglected in conventional image captioning. Most existing image captioning models cannot be applied directly to social image captioning. In this work, a dual attention model is proposed for social image captioning by combining the visual attention and user attention simultaneously.Visual attention is used to compress a large mount of salient visual information, while user attention is applied to adjust the description of the social images with user-contributed tags. Experiments conducted on the Microsoft (MS COCO dataset demonstrate the superiority of the proposed method of dual attention.

    Intra-subject variability (ISV) is the most consistent behavioral deficit in Attention Deficit Hyperactivity Disorder (ADHD). ISV may be associated with networks involved in sustaining task control (cingulo-opercular network: CON) and self-reflective lapses of attention (default mode network: DMN). The current study examined whether connectivity supporting attentional control is atypical in children with ADHD. Group differences in full-brain connection strength and brain-behavior associations with attentional control measures were examined for the late-developing CON and DMN in 50 children with ADHD and 50 typically-developing (TD) controls (ages 8-12 years). Children with ADHD had hyper-connectivity both within the CON and within the DMN. Full-brain behavioral associations were found for a number of between-network connections. Across both groups, more anti-correlation between DMN and occipital cortex supported better attentional control. However, in the TD group, this brain-behavior association was stronger and occurred for a more extensive set of DMN-occipital connections. Differential support for attentional control between the two groups occurred with a number of CON-DMN connections. For all CON-DMN connections identified, increased between-network anti-correlation was associated with better attentional control for the ADHD group, but worse attentional control in the TD group. A number of between-network connections with the medial frontal cortex, in particular, showed this relationship. Follow-up analyses revealed that these associations were specific to attentional control and were not due to individual differences in working memory, IQ, motor control, age, or scan motion. While CON-DMN anti-correlation is associated with improved attention in ADHD, other circuitry supports improved attention in TD children. Greater CON-DMN anti-correlation supported better attentional control in children with ADHD, but worse attentional control in TD children. On the other

    User Modeling and Adaptation for Daily Routines is motivated by the need to bring attention to how people with special needs can benefit from adaptive methods and techniques in their everyday lives. Assistive technologies, adaptive systems and context-aware applications are three well-established research fields. There is, in fact, a vast amount of literature that covers HCI-related issues in each area separately. However, the contributions in the intersection of these areas have been less visible, despite the fact that such synergies may have a great impact on improving daily living.Presentin

    Too often, people fail to prioritize the most important activities, life domains, and budget categories. One reason for misplaced priorities, we argue, is that activities and categories people have frequently or recently attended to seem higher priority than other activities and categories. In Experiment 1, participants were cued to direct voluntary spatial attention toward 1 side of a screen while images depicting different budget categories were presented: 1 category on the cued side and 1 on the noncued side of the screen. Participants rated cued budget categories as higher priority than noncued budget categories. Cued attention also increased perceived distinctiveness, and a mediation model was consistent with the hypothesis that distinctiveness mediates the effect of cued attention on prioritization. Experiment 2 orthogonally manipulated 2 components of a spatial cuing manipulation-heightened visual attention and heightened mental attention-to examine how each influences prioritization. Visual attention and mental attention additively increased prioritization. In Experiment 3, attention increased prioritization even when prioritization decisions were incentivized, and even when heightened attention was isolated from primacy and recency. Across experiments, cued categories were prioritized more than noncued categories even though measures were taken to disguise the purpose of the experiments and manipulate attention incidentally (i.e., as a by-product of an unrelated task).

  10. Assessment of Attention in Preschoolers

    2012-01-01

    In the past two decades, there has been an increased interest in the assessment and treatment of preschool children presenting with concerns about attention problems. This article reviews the research and clinical literature involving assessment of attention and related skills in the preschool years. While inattention among preschoolers is common, symptoms alone do not necessarily indicate a disorder, and most often represent a normal variation in typical preschool child development. Thus, accurate identification of “disordered” attention in preschoolers can be challenging, and development of appropriate, norm-referenced tests of attention for preschoolers is also difficult. The current review suggests that comprehensive assessment of attention and related functions in the preschool child should include thorough review of the child’s history, planned observations, and formal psychometric testing. The three primary methods of psychometric assessment that have been used to characterize attentional functioning in preschool children include performance-based tests, structured caregiver interviews, and rating scales (parent, teacher, and clinician). Among performance-based methods for measurement of attention in the preschool years, tests have been developed to assess sustained attention, selective (focused) attention, span of attention (encoding/manipulation), and (top-down) controlled attention—including freedom from distractibility and set shifting. Many of these tests remain experimental in nature, and review of published methods yields relatively few commercially available, nationally normed tests of attention for preschoolers, and an overall dearth of reliability and validity studies on the available measures.

    Certain abnormalities in behavioral performance and neural signaling have been attributed to a deficit of visual attention in amblyopia, a neurodevelopmental disorder characterized by a diverse array of visual deficits following abnormal binocular childhood experience. Critically, most have inferred attention's role in their task without explicitly manipulating and measuring its effects against a baseline condition. Here, we directly investigate whether human amblyopic adults benefit from covert spatial attention—the selective processing of visual information in the absence of eye movements—to the same degree as neurotypical observers. We manipulated both involuntary (Experiment 1) and voluntary (Experiment 2) attention during an orientation discrimination task for which the effects of covert spatial attention have been well established in neurotypical and special populations. In both experiments, attention significantly improved accuracy and decreased reaction times to a similar extent (a) between the eyes of the amblyopic adults and (b) between the amblyopes and their age- and gender-matched controls. Moreover, deployment of voluntary attention away from the target location significantly impaired task performance (Experiment 2). The magnitudes of the involuntary and voluntary attention benefits did not correlate with amblyopic depth or severity. Both groups of observers showed canonical performance fields (better performance along the horizontal than vertical meridian and at the lower than upper vertical meridian) and similar effects of attention across locations. Despite their characteristic low-level vision impairments, covert spatial attention remains functionally intact in human amblyopic adults. PMID:28033433

  13. The Dance of Attention: Toward an Aesthetic Dimension of Attention-Deficit.

    2018-03-01

    What role does the aesthetics of bodily movement play in the understanding of attention among children diagnosed with attention-deficit/hyperactivity disorder (ADHD)? This article animates a phenomenological approach to attention and embodiment with a special focus on the relation between aesthetic or expressive bodily movement and behavioral awareness in children diagnosed with ADHD. However, beyond this it is argued that the aesthetic aspect of movement calls for an expansion of the phenomenological perspective. In this context Gilles Deleuze's notion of aesthetics as a "science of the sensible" is activated and discussed in relation to the phenomenological concept of perception. Empirically the article takes point of departure in a qualitative study conducted with a group of children with attention-deficit practicing the Afro-Brazilian marital art, capoeira. Combining ethnographic and phenomenological methods, it is demonstrated that capoeira can be considered a form of aesthetic movement that offers a transition of attention-deficit into a productive force of expression that changes the notions of sensation and movement in ADHD.

    This study was designed to evaluate the efficacy of a new specially engineered sonic powered toothbrush with unique sensing and control technologies, as compared to a manual flat-trim toothbrush on supragingival plaque and established gingivitis. This examiner-blind, two-treatment, parallel clinical research study assessed plaque removal via the comparison of pre- to post-brushing after a single use, and again after four- and 12-weeks' use using the Rustogi Modification of the Modified Navy Plaque Index. This study also assessed gingivitis at four and 12 weeks using the Löe and Silness Gingival Index. Qualifying adult male and female subjects from the southern Florida area reported to the study site after refraining from any oral hygiene procedures for 24 hours, and from eating, drinking, and smoking for four hours. Following an examination for plaque (pre-brushing) and gingivitis, they were randomized (for both plaque and gingivitis) into two balanced groups, each group using one of the two study toothbrushes. Subjects were instructed to brush their teeth for two minutes under supervision with their assigned toothbrush according to the manufacturer's instructions, and commercially available toothpaste (Colgate Cavity Protection Toothpaste), after which they were again evaluated for plaque (post-brushing). Subjects were then dismissed from the study site with the toothpaste and their assigned toothbrush to use at home twice daily for the next 12 weeks. They again reported to the study site after four and 12 weeks of product use, at which time they were evaluated for plaque and gingivitis. Seventy-six out of 82 enrolled subjects complied with the protocol and completed the clinical study. The new specially engineered sonic powered toothbrush with unique sensing and control technologies provided statistically significant reductions in gingival and gingivitis severity index scores after four and 12 weeks of product use. The manual toothbrush provided a statistically

  20. Attentional modulation of binocular rivalry

    Directory of Open Access Journals (Sweden)

    Chris ePaffen

    2011-09-01

    Full Text Available Ever since Wheatstone initiated the scientific study of binocular rivalry, it has been debated whether the phenomenon is under attentional control. In recent years, the issue of attentional modulation of binocular rivalry has seen a revival. Here we review the classical studies as well as recent advances in the study of attentional modulation of binocular rivalry. We show that (1 voluntary control over binocular rivalry is possible, yet limited, (2 both endogenous and exogenous attention influence perceptual dominance during rivalry, (3 diverting attention from rival displays does not arrest perceptual alternations, and that (4 rival targets by themselves can also attract attention. From a theoretical perspective, we suggest that attention affects binocular rivalry by modulating the effective contrast of the images in competition. This contrast enhancing effect of top-down attention is counteracted by a response attenuating effect of neural adaptation at early levels of visual processing, which weakens the response to the dominant image. Moreover, we conclude that although frontal and parietal brain areas involved in both binocular rivalry and visual attention overlap, an adapting reciprocal inhibition arrangement at early visual cortex is sufficient to trigger switches in perceptual dominance independently of a higher-level ‘selection’ mechanisms. Both of these processes are reciprocal and therefore self-balancing, with the consequence that complete attentional control over binocular rivalry can never be realized.

    Voluntary (endogenous, sustained) covert spatial attention selects relevant sensory information for prioritized processing. The behavioral and neural consequences of such selection have been extensively documented, but its phenomenology has received little empirical investigation. We asked whether voluntary attention affects the subjective appearance of contrast--a fundamental dimension of visual perception. We used a demanding rapid serial visual presentation (RSVP) task to direct endogenous attention to a given location and measured perceived contrast at the attended and unattended locations. Attention increased perceived contrast of suprathreshold stimuli and also improved performance on a concurrent orientation discrimination task at the cued location. We ruled out response bias as an alternative account of the pattern of results. Thus, this study establishes that voluntary attention enhances perceived contrast. This phenomenological consequence links behavioral and neurophysiological studies on the effects of attention.

  4. Selective attention within the foveola.

    Efficient control of attentional resources and high-acuity vision are both fundamental for survival. Shifts in visual attention are known to covertly enhance processing at locations away from the center of gaze, where visual resolution is low. It is unknown, however, whether selective spatial attention operates where the observer is already looking-that is, within the high-acuity foveola, the small yet disproportionally important rod-free region of the retina. Using new methods for precisely controlling retinal stimulation, here we show that covert attention flexibly improves and speeds up both detection and discrimination at loci only a fraction of a degree apart within the foveola. These findings reveal a surprisingly precise control of attention and its involvement in fine spatial vision. They show that the commonly studied covert shifts of attention away from the fovea are the expression of a global mechanism that exerts its action across the entire visual field.

    2015-04-01

    Traditionally, the right cerebral hemisphere has been considered to be specialized for spatial attention and orienting. A large body of research has demonstrated dissociable representations of the near space immediately surrounding the body and the more distance far space. In this study, we investigated whether right hemisphere activations commonly reported for tasks involving spatial attention (such as the line bisection and landmark tasks) are specific to stimuli presented in near space. In separate blocks of trials, participants judged either whether a vertical transector was to the left or right of the centre of a line (landmark task) or whether the line was red or blue (colour task). Stimuli were seen from four distances (30, 60, 90, 120 cm). We used EEG to measure an ERP component (the 'line-bisection effect') specific to the direction of spatial attention (i.e., landmark minus colour). Consistent with previous results, spatial attention produced a right-lateralized negativity over occipito-parietal channels. The magnitude of this negativity was inversely related to viewing distance, being largest in near space and reduced in far space. These results suggest that the right occipito-temporal cortex may be specialized not just for the orientation of spatial attention generally, but specifically for orienting attention in the near space immediately surrounding the body.

    Full Text Available Abstract Background Very little is known about attention deficits in developmental dyscalculia, hence, this study was designed to provide the missing information. We examined attention abilities of participants suffering from developmental dyscalculia using the attention networks test - interactions. This test was designed to examine three different attention networks--executive function, orienting and alerting--and the interactions between them. Methods Fourteen university students that were diagnosed as suffering from developmental dyscalculia--intelligence and reading abilities in the normal range and no indication of attention-deficit hyperactivity disorder--and 14 matched controls were tested using the attention networks test - interactions. All participants were given preliminary tests to measure mathematical abilities, reading, attention and intelligence. Results The results revealed deficits in the alerting network--a larger alerting effect--and in the executive function networks--a larger congruity effect in developmental dyscalculia participants. The interaction between the alerting and executive function networks was also modulated by group. In addition, developmental dyscalculia participants were slower to respond in the non-cued conditions. Conclusions These results imply specific attentional deficits in pure developmental dyscalculia. Namely, those with developmental dyscalculia seem to be deficient in the executive function and alertness networks. They suffer from difficulty in recruiting attention, in addition to the deficits in numerical processing.

  12. Preparatory attention in visual cortex.

    Battistoni, Elisa; Stein, Timo; Peelen, Marius V

    2017-05-01

    Top-down attention is the mechanism that allows us to selectively process goal-relevant aspects of a scene while ignoring irrelevant aspects. A large body of research has characterized the effects of attention on neural activity evoked by a visual stimulus. However, attention also includes a preparatory phase before stimulus onset in which the attended dimension is internally represented. Here, we review neurophysiological, functional magnetic resonance imaging, magnetoencephalography, electroencephalography, and transcranial magnetic stimulation (TMS) studies investigating the neural basis of preparatory attention, both when attention is directed to a location in space and when it is directed to nonspatial stimulus attributes (content-based attention) ranging from low-level features to object categories. Results show that both spatial and content-based attention lead to increased baseline activity in neural populations that selectively code for the attended attribute. TMS studies provide evidence that this preparatory activity is causally related to subsequent attentional selection and behavioral performance. Attention thus acts by preactivating selective neurons in the visual cortex before stimulus onset. This appears to be a general mechanism that can operate on multiple levels of representation. We discuss the functional relevance of this mechanism, its limitations, and its relation to working memory, imagery, and expectation. We conclude by outlining open questions and future directions. © 2017 New York Academy of Sciences.

    The aim of this study was to examine the specific aspects of attention, such as selective attention, sustained attention, and short-term memory in children with attention deficit hyperactivity disorder, combined subtype (ADHD-C). A total of 40 children with a diagnosis of ADHD from the 4th edition of the Diagnostic and Statistical Manual, aged 6-11 years old were compared with 40 controls matched for age and gender on a battery of tests. Short-term memory span and attention was measured by Visual Aural Digit Span Test-Revised. Stroop test and the Turkish version of Cancellation Test were used to assess selective and sustained attention, respectively. In order to check for factor structure in two groups on the test scores, principal component analysis was conducted for both groups separately. Relative to the comparison children, children with ADHD showed significant deficits on tests that are related to different aspects of attention. The results are consistent with the theories explaining the biological basis of ADHD by scattered attention networks in the brain, which have reciprocal dynamic interactions. Further comparative studies are needed to elucidate whether the cognitive processes that are known to be assessed by these tests are specific to ADHD.

    Imaging mass spectrometry techniques have become a powerful strategy to assess the spatial distribution of metabolites in biological systems. Based on auto-ionisability of lichen metabolites using LDI-MS, we herein image the distribution of major secondary metabolites (specialized metabolites) from the lichen Ophioparma ventosa by LDI-MSI (Mass Spectrometry Imaging). Such technologies offer tremendous opportunities to discuss the role of natural products through spatial mapping, their distribution patterns being consistent with previous chemical ecology reports. A special attention was dedicated to miriquidic acid, an unexpected molecule we first reported in Ophioparma ventosa. The analytical strategy presented herein offers new perspectives to access the sharp distribution of lichen metabolites from regular razor blade-sectioned slices.

    Full Text Available Specific Learning Disorder with impairment in Mathematics (Developmental Dyscalculia is a complex learning disorder which affects arithmetic skills, symbolic magnitude processing, alertness, flexibility in problem solving and maintained attention. Neuro-cognitive studies revealed that such difficulties in children with DD could be related to poor Working Memory and attention deficits. Furthermore, neuroimaging studies indicate that brain structure differences in children with DD compared to typically developing children could affect mathematical performance. In this study we present the cognitive profile of Dyscalculia, as well as the neuropsychological aspects of the deficit, with special reference to the utilization of enhanced assessment technology such as computerized neuropsychological tools and neuroimaging techniques.

    Attention selects which aspects of sensory input are brought to awareness. To promote survival and well-being, attention prioritizes stimuli both voluntarily, according to context-specific goals (e.g., searching for car keys), and involuntarily, through attentional capture driven by physical salience (e.g., looking toward a sudden noise). Valuable stimuli strongly modulate voluntary attention allocation, but there is little evidence that high-value but contextually irrelevant stimuli capture attention as a consequence of reward learning. Here we show that visual search for a salient target is slowed by the presence of an inconspicuous, task-irrelevant item that was previously associated with monetary reward during a brief training session. Thus, arbitrary and otherwise neutral stimuli imbued with value via associative learning capture attention powerfully and persistently during extinction, independently of goals and salience. Vulnerability to such value-driven attentional capture covaries across individuals with working memory capacity and trait impulsivity. This unique form of attentional capture may provide a useful model for investigating failures of cognitive control in clinical syndromes in which value assigned to stimuli conflicts with behavioral goals (e.g., addiction, obesity).

  9. Combining segmentation and attention: a new foveal attention model

    2014-08-01

    Full Text Available Artificial vision systems cannot process all the information that they receive from the world in real time because it is highly expensive and inefficient in terms of computational cost. Inspired by biological perception systems, articial attention models pursuit to select only the relevant part of the scene. Besides, it is well established that the units of attention on human vision are not merely spatial but closely related to perceptual objects (proto-objects. This implies a strong bidirectional relationship between segmentation and attention processes. Therefore, while the segmentation process is the responsible to extract the proto-objects from the scene, attention can guide segmentation, arising the concept of foveal attention. When the focus of attention is deployed from one visual unit to another, the rest of the scene is perceived but at a lower resolution that the focused object. The result is a multi-resolution visual perception in which the fovea, a dimple on the central retina, provides the highest resolution vision. In this paper, a bottom-up foveal attention model is presented. In this model the input image is a foveal image represented using a Cartesian Foveal Geometry (CFG, which encodes the field of view of the sensor as a fovea (placed in the focus of attention surrounded by a set of concentric rings with decreasing resolution. Then multirresolution perceptual segmentation is performed by building a foveal polygon using the Bounded Irregular Pyramid (BIP. Bottom-up attention is enclosed in the same structure, allowing to set the fovea over the most salient image proto-object. Saliency is computed as a linear combination of multiple low level features such us colour and intensity contrast, symmetry, orientation and roundness. Obtained results from natural images show that the performance of the combination of hierarchical foveal segmentation and saliency estimation is good in terms of accuracy and speed.

  10. Brain activity associated with selective attention, divided attention and distraction.

    Top-down controlled selective or divided attention to sounds and visual objects, as well as bottom-up triggered attention to auditory and visual distractors, has been widely investigated. However, no study has systematically compared brain activations related to all these types of attention. To this end, we used functional magnetic resonance imaging (fMRI) to measure brain activity in participants performing a tone pitch or a foveal grating orientation discrimination task, or both, distracted by novel sounds not sharing frequencies with the tones or by extrafoveal visual textures. To force focusing of attention to tones or gratings, or both, task difficulty was kept constantly high with an adaptive staircase method. A whole brain analysis of variance (ANOVA) revealed fronto-parietal attention networks for both selective auditory and visual attention. A subsequent conjunction analysis indicated partial overlaps of these networks. However, like some previous studies, the present results also suggest segregation of prefrontal areas involved in the control of auditory and visual attention. The ANOVA also suggested, and another conjunction analysis confirmed, an additional activity enhancement in the left middle frontal gyrus related to divided attention supporting the role of this area in top-down integration of dual task performance. Distractors expectedly disrupted task performance. However, contrary to our expectations, activations specifically related to the distractors were found only in the auditory and visual cortices. This suggests gating of the distractors from further processing perhaps due to strictly focused attention in the current demanding discrimination tasks. Copyright © 2017 Elsevier B.V.

    Adults with attention deficit hyperactivity disorder (ADHD) show attentional dysfunction such as distractibility and mind-wandering, especially in lengthy tasks. However, fundamentals of dysfunction are ambiguous and relationships of neuropsychological test parameters with self-report measures of ADHD symptoms are marginal. We hypothesize that basic deficits in sustaining attention explain more complex attentional dysfunction in persons with ADHD and relate to ADHD symptoms. Attentional function was analyzed by computing ex-Gaussian parameters for 3 time Blocks in a 20 min test of sustained alertness. Changes in performance across these blocks were analyzed by comparing adult persons with ADHD (n = 24) with healthy matched controls (n = 24) and correlated with neuropsychological measures of selective and divided attention as well as self-report measures of ADHD symptoms. We found a significantly steeper increase in the number of slow responses (ex-Gaussian parameter τ) in persons with ADHD with time on task in basic sustained alertness. They also performed significantly worse in tasks of sustained selective and divided attention. However, after controlling for an increase in τ during the alertness task, significant differences between groups disappeared for divided and partly selective attention. Increases in τ in the sustained alertness task correlated significantly with self-report measures of ADHD symptoms. Our results provide evidence that very basic deficits in sustaining attention in adults with ADHD are related to infrequent slow responses (=attentional lapses), with changes over time being relevant for more complex attentional function and experienced ADHD symptoms in everyday life. © The Author 2016.

  16. Selective attention without a neocortex.

    Krauzlis, Richard J; Bogadhi, Amarender R; Herman, James P; Bollimunta, Anil

    2018-05-01

    Selective attention refers to the ability to restrict neural processing and behavioral responses to a relevant subset of available stimuli, while simultaneously excluding other valid stimuli from consideration. In primates and other mammals, descriptions of this ability typically emphasize the neural processing that takes place in the cerebral neocortex. However, non-mammals such as birds, reptiles, amphibians and fish, which completely lack a neocortex, also have the ability to selectively attend. In this article, we survey the behavioral evidence for selective attention in non-mammals, and review the midbrain and forebrain structures that are responsible. The ancestral forms of selective attention are presumably selective orienting behaviors, such as prey-catching and predator avoidance. These behaviors depend critically on a set of subcortical structures, including the optic tectum (OT), thalamus and striatum, that are highly conserved across vertebrate evolution. In contrast, the contributions of different pallial regions in the forebrain to selective attention have been subject to more substantial changes and reorganization. This evolutionary perspective makes plain that selective attention is not a function achieved de novo with the emergence of the neocortex, but instead is implemented by circuits accrued and modified over hundreds of millions of years, beginning well before the forebrain contained a neocortex. Determining how older subcortical circuits interact with the more recently evolved components in the neocortex will likely be crucial for understanding the complex properties of selective attention in primates and other mammals, and for identifying the etiology of attention disorders.

  17. Cold-Blooded Attention: Finger Temperature Predicts Attentional Performance

    2017-01-01

    Thermal stress has been shown to increase the chances of unsafe behavior during industrial and driving performances due to reductions in mental and attentional resources. Nonetheless, establishing appropriate safety standards regarding environmental temperature has been a major problem, as modulations are also be affected by the task type, complexity, workload, duration, and previous experience with the task. To bypass this attentional and thermoregulatory problem, we focused on the body rather than environmental temperature. Specifically, we measured tympanic, forehead, finger and environmental temperatures accompanied by a battery of attentional tasks. We considered a 10 min baseline period wherein subjects were instructed to sit and relax, followed by three attentional tasks: a continuous performance task (CPT), a flanker task (FT) and a counting task (CT). Using multiple linear regression models, we evaluated which variable(s) were the best predictors of performance. The results showed a decrement in finger temperature due to instruction and task engagement that was absent when the subject was instructed to relax. No changes were observed in tympanic or forehead temperatures, while the environmental temperature remained almost constant for each subject. Specifically, the magnitude of the change in finger temperature was the best predictor of performance in all three attentional tasks. The results presented here suggest that finger temperature can be used as a predictor of alertness, as it predicted performance in attentional tasks better than environmental temperature. These findings strongly support that peripheral temperature can be used as a tool to prevent unsafe behaviors and accidents. PMID:28955215

    The aim of this study was to evaluate the efficiency and interactions of attentional systems in children with Attention Deficit Hyperactivity Disorder (ADHD) by considering the effects of reinforcement and auditory warning on each component of attention. Thirty-six drug-naïve children (18 children with ADHD/18 typically developing children) performed two revised versions of the Attentional Network Test, which assess the efficiency of alerting, orienting, and executive systems. In feedback trials, children received feedback about their accuracy, whereas in the no-feedback trials, feedback was not given. In both conditions, children with ADHD performed more slowly than did typically developing children. They also showed impairments in the ability to disengage attention and in executive functioning, which improved when alertness was increased by administering the auditory warning. The performance of the attentional networks appeared to be modulated by the absence or the presence of reinforcement. We suggest that the observed executive system deficit in children with ADHD could depend on their low level of arousal rather than being an independent disorder. © The Author 2011.

    In recent years, there is an increasing awareness that individuals may purposely feign or exaggerate symptoms of attention deficit hyperactivity disorder (ADHD) to gain external incentives, including access to stimulant drugs or special academic accommodations. There are vast consequences of undetected feigned ADHD such as substantial costs covered by society for unnecessary assessments and treatments, unjustified occupation of limited medical resources and undermining society's trust in the existence of the disorder or the effectiveness of treatment. In times of economic crisis and cost savings in the medical sector, the detection of feigned ADHD is of importance. This review briefly describes the research on this topic with an emphasis on the approaches available for detection of feigned ADHD (i.e., self-report questionnaires, personality inventories, cognitive tests used in routine neuropsychological assessment and tests specifically designed for detecting feigned cognitive dysfunction). Promising approaches and measures are available for identifying feigned ADHD but there is an immediate need for further research.

    Several studies have demonstrated the beneficial effects of meditation on attention. The present study investigated the relationship between focused attention (FA) and open monitoring (OM) meditation skills and the various functions of attention. In Experiment 1, we executed the attention network test and compared the performance of experts on dandao meditation with that of ordinary people on this test. The results indicated that the experts specializing in OM meditation demonstrated greater attentional orienting ability compared with those specializing in FA meditation and the control group. In addition, both expert groups registered improvements in their executive control abilities compared with the control group. In Experiment 2, we trained beginners in FA meditation for 3months. The results showed that the experimental group exhibited significantly enhanced executive control ability. We infer that FA meditation skills promote executive control function and OM meditation skills promote both executive control and attentional orienting functions. Copyright © 2016 Elsevier Inc.

In the early 1980s, Treisman proposed the feature integration theory of attention (FIT, based on the findings of neuroscience. Soon after publishing her theory a new scientific approach appeared investigating several visual perception phenomena. The most widely researched were the key constructs of FIT, like types of visual search and the role of the attention.

    In present, with the help of computer, we can create special effects that look so real that we almost don't perceive them as being different. These special effects are somehow hard to differentiate from the real elements like those on the screen. With the increasingly accesible 3D field that has more and more areas of application, the 3D technology goes easily from architecture to product designing. Real like 3D animations are used as means of learning, for multimedia presentations of big global corporations, for special effects and even for virtual actors in movies. Technology, as part of the movie art, is considered a prerequisite but the cinematography is the first art that had to wait for the correct intersection of technological development, innovation and human vision in order to attain full achievement. Increasingly more often, the majority of industries is using 3D sequences (three dimensional). 3D represented graphics, commercials and special effects from movies are all designed in 3D. The key for attaining real visual effects is to successfully combine various distinct elements: characters, objects, images and video scenes; like all these elements represent a whole that works in perfect harmony. This article aims to exhibit a game design from these days. Considering the advanced technology and futuristic vision of designers, nowadays we have different and multifarious game models. Special effects are decisively contributing in the creation of a realistic three-dimensional scene. These effects are essential for transmitting the emotional state of the scene. Creating the special effects is a work of finesse in order to achieve high quality scenes. Special effects can be used to get the attention of the onlooker on an object from a scene. Out of the conducted study, the best-selling game of the year 2010 was Call of Duty: Modern Warfare 2. This way, the article aims for the presented scene to be similar with many locations from this type of games, more

    Fabricius, Charlotte; Petersen, Anders; Iversen, Helle K

    Objective: Impaired visual attention is common following strokes in the territory of the middle cerebral artery, particularly in the right hemisphere. However, attentional effects of more posterior lesions are less clear. The aim of this study was to characterize visual processing speed...... and apprehension span following posterior cerebral artery (PCA) stroke. We also relate these attentional parameters to visual word recognition, as previous studies have suggested that reduced visual speed and span may explain pure alexia. Methods: Nine patients with MR-verified focal lesions in the PCA......-territory (four left PCA; four right PCA; one bilateral, all >1 year post stroke) were compared to 25 controls using single case statistics. Visual attention was characterized by a whole report paradigm allowing for hemifield-specific speed and span measurements. We also characterized visual field defects...

    . This phenomenon is known as attentional dwell time (e.g. Duncan, Ward, Shapiro, 1994). All Previous studies of the attentional dwell time have looked at data averaged across subjects. In contrast, we have succeeded in running subjects for 3120 trials which has given us reliable data for modelling data from...... of attentional dwell time extends these mechanisms by proposing that the processing resources (cells) already engaged in a feedback loop (i.e. allocated to an object) are locked in VSTM and therefore cannot be allocated to other objects in the visual field before the encoded object has been released....... This confinement of attentional resources leads to the impairment in identifying the second target. With the model, we are able to produce close fits to data from the traditional two target dwell time paradigm. A dwell-time experiment with three targets has also been carried out for individual subjects...

  13. Voluntary attention enhances contrast appearance

    OpenAIRE

    Liu, Taosheng; Abrams, Jared; Carrasco, Marisa

    2009-01-01

    Voluntary (endogenous, sustained) covert spatial attention selects relevant sensory information for prioritized processing. The behavioral and neural consequences of such selection have been extensively documented, but its phenomenology has received little empirical investigation. Here we ask whether voluntary attention affects the subjective appearance of contrast—a fundamental dimension of visual perception. We used a demanding rapid serial visual presentation (RSVP) task to direct endogeno...

  14. Visual Selective Attention in Mice.

    Wang, Lupeng; Krauzlis, Richard J

    2018-02-08

    Visual selective attention is a fundamental cognitive ability that allows us to process relevant visual stimuli while ignoring irrelevant distracters and has been extensively studied in human and non-human primate subjects. Mice have emerged as a powerful animal model for studying aspects of the visual system but have not yet been shown to exhibit visual selective attention. Differences in the organization of the visual systems of primates and mice raise the possibility that selective visual attention might not be present in mice, at least not in the forms that are well established in primates. Here, we tested for selective visual attention in mice by using three behavioral paradigms adapted from classic studies of attention. In a Posner-style cueing task, a spatial cue indicated the probable location of the relevant visual event, and we found that accuracy was higher and reaction times were shorter on validly cued trials. In a cue versus no-cue task, an informative spatial cue was provided on half the trials, and mice had higher accuracy and shorter reaction times with spatial cues and also lower detection thresholds measured from psychometric curves. In a filter task, the spatial cue indicated the location of the relevant visual event, and we found that mice could be trained to ignore irrelevant but otherwise identical visual events at uncued locations. Together, these results demonstrate that mice exhibit visual selective attention, paving the way to use classic attention paradigms in mice to study the genetic and neuronal circuit mechanisms of selective attention.

    Those practicing Emergency Medicine are frequently faced with a patient presenting with a chemical burn. Most dermal chemical burns are minor and do not require specialized treatment. Occasionally, however, the clinician may be in the position of responding to a chemical burn in which standard therapy of irrigation and good wound care may not be sufficient or, at worst, contraindicated. Several burn conditions will be reviewed, some of those requiring only specific decontamination techniques, as in hot tar, others posing special hazards to clinicians, as in elemental metals, and finally, examples are given of hazardous materials requiring attention to systemic effects, as in hydrofluoric acid.

  16. Dividing Attention Increases Operational Momentum

    Directory of Open Access Journals (Sweden)

    Koleen McCrink

    2017-12-01

    Full Text Available When adding or subtracting two quantities, adults often compute an estimated outcome that is larger or smaller, respectively, than the actual outcome, a bias referred to as “operational momentum”. The effects of attention on operational momentum were investigated. Participants viewed a display in which two arrays of objects were added, or one array was subtracted from another array, and judged whether a subsequent outcome (probe array contained the correct or incorrect number of objects. In a baseline condition, only the arrays to be added or subtracted were viewed. In divided attention conditions, participants simultaneously viewed a sequence of colors or shapes, and judged which color (a non-spatial judgment or shape (a spatial judgment was repeated. Operational momentum occurred in all conditions, but was higher in divided attention conditions than in the baseline condition, primarily for addition problems. This pattern suggests that dividing attention, rather than decreasing operational momentum by decreasing attentional shifts, actually increased operational momentum. These results are consistent with a heightened use of arithmetic heuristics under conditions of divided attention.

    1987-08-01

    At first, accelerators were developed for the research on atomic nuclei, but as the research on the components of natural world advanced, they were made larger so as to reach higher energy, and developed so that diverse particles can be accelerated. The energy attainable with accelerators has increased to ten times in six years. To the advance of accelerators, the development of acceleration principle due to new idea or the development of the technology related to accelerators accompanied without exception. In particular, as accelerators became large scale, and their construction requires large amount of money, attention is paid to the technical development required for the construction of new accelerators as the extending effect which brings forth the technical innovation in the society. In this paper, the technical advance which is common to accelerators is outlined. As the components indispensable to accelerators, there are charged particle generators, accelerating electric field generators, vaccumizing facilities, control system, diagnostic system and so on. As to new accelerating principles, the materialization of collision type rings and beam cooling is worthy of special mention. The research on computer-aided accelerators and the techniques of accelerating electric field generation, vaccumizing, electromagnets, ion sources and others are reported. (Kako, I.).

    Deng, Wei (Sophia); Sloutsky, Vladimir M.

    2016-01-01

    How do people learn categories and what changes with development? The current study attempts to address these questions by focusing on the role of attention in the development of categorization. In Experiment 1, participants (adults, 7-year-olds, and 4-year-olds) were trained with novel categories consisting of deterministic and probabilistic features, and their categorization and memory for features were tested. In Experiment 2, participants’ attention was directed to the deterministic feature, and in Experiment 3 it was directed to the probabilistic features. Attentional cuing affected categorization and memory in adults and 7-year-olds: these participants relied on the cued features in their categorization and exhibited better memory of cued than of non-cued features. In contrast, in 4-year-olds attentional cueing affected only categorization, but not memory: these participants exhibited equally good memory for both cued and non-cued features. Furthermore, across the experiments, 4-year-olds remembered non-cued features better than adults. These results coupled with computational simulations provide novel evidence (1) pointing to differences in category representation and mechanisms of categorization across development, (2) elucidating the role of attention in the development of categorization, and (3) suggesting an important distinction between representation and decision factors in categorization early in development. These issues are discussed with respect to theories of categorization and its development. PMID:27721103

    Attention-deficit hyperactivity disorder (ADHD) is a heterogeneous disorder currently defined by clinical history and behavioral report of impairment. The Attention Network test (ANT) gives measures of different aspects of the complex process of attention. We ask if children with Attention Deficit Hyperactivity Disorder (ADHD) will show a characteristic pattern of deficits on this test. The sample included 40 children (M=9 years) who performed the "Attention network test". Children with an ADHD diagnosis (N=20) were compared to a control group (N=20). The group of children with ADHD showed slower reaction times in all conditions (mean RT=866 ms; SD=234,063). Children with ADHD showed a significant impairment in their executive control system compared to healthy subjects, with slower reaction times in incongruent conditions and lower accuracy scores (RT=1064 ms; F(1.38) p=0.02). Our results showed that spatial orienting and alerting in ADHD was no different than controls (p=0,68). ADHD group showed a greater variable response (p=0,0001). The present study showed that impairment in executive control system and variability measures are the characteristic pattern of deficits in children with ADHD.

  2. INTERNATIONAL SPECIALIZATION AND VERTICAL DIFFERENTIATION

    Directory of Open Access Journals (Sweden)

    Furia Donatella

    2010-07-01

    Full Text Available During the last decades, market segmentation and intra-industry trade have become increasingly relevant. The underlying hypothesis of our work is that distinct articles have heterogeneous potential for vertical differentiation, implying that different patterns of international specialization should be identifiable. We carry out an analysis on revealed comparative advantage (through the Lafay Index in specific sectors of interest. Then we highlight the emergence of diverse degrees of product quality differentiation among sectors (through the Relative Quality Index. Results confirm our hypothesis. Indeed it appears that only certain goods, for which the pace of either creative or technological innovation (or both is particularly fast, present a high degree of vertical differentiation and market segmentation. This allows countries to specialize in a particular product variety and gain market power position for that variety. These findings should be taken in due consideration when designing trade policies.

    Modern communication platforms require a huge amount of switched RF component banks especially made of different filters and antennas to cover all operating frequencies and bandwidth for the targeted services and application scenarios. In contrast, reconfigurable devices made of tunable components lead to a considerable reduction in complexity, size, weight, power consumption, and cost. This paper gives an overview of suitable technologies for tunable microwave components especially for SatCom applications. Special attention is given to tunable components based on functional materials such as barium strontium titanate (BST) and liquid crystal (LC).

    T'he CERN Courier is the international journal of high energy physics, covering current developments in and around this branch of basic science. A recurrent theme is applying the technology developed for particle accelerators, the machines which produce beams of high energy particles for physics experiments. Twentieth-century science is full of similar examples of applications derived from pure research. This special issue of the CERN Courier is given over to one theme - the applications of accelerators. Accelerator systems and facilities are normally associated with highenergy particle physics research, the search for fundamental particles and the quest to understand the physics of the Big Bang. To the layman, accelerator technology has become synonymous with large and expensive machines, exploiting the most modern technology for basic research. In reality, the range of accelerators and their applications is much broader. A vast number of accelerators, usually much smaller and operating for specific applications, create wealth and directly benefit the population, particularly in the important areas of healthcare, energy and the environment. There are well established applications in diagnostic and therapeutic medicine for research and routine clinical treatments. Accelerators and associated technologies are widely employed by industry for manufacturing and process control. In fundamental and applied research, accelerator systems are frequently used as tools. The biennial conference on the Applications of Accelerators in Industry and Research at Denton, Texas, attracts a thousand participants. This special issue of the CERN Courier includes articles on major applications, reflecting the diversity and value of accelerator technology. Under Guest Editor Dewi Lewis of Amersham International, contributions from leading international specialists with experience of the application end of the accelerator chain describe their fields of direct interest.

    Human social behavior is fine-tuned by interactions between individuals and their environments. Here we show that social motivation plays an important role in this process. Using a novel manipulation of social reward that included elements of real-life social exchanges, we demonstrate the emergence of attentional orienting for coincidental spatial associations that received positive social reward. After an interaction with the experimenter, participants completed a computerized task in which they received positive, negative, or no social reward for their performance to spatially congruent, spatially incongruent, and neutral cue-target pairings, respectively. Even though cue-target spatial correspondences remained at chance, attentional benefits emerged and persisted a day later for targets that received positive social reward. Our data further revealed that participants' level of social competence, as measured by the Autism-Spectrum Quotient scale, was predictably related to the magnitude of their reward-driven attentional benefits. No attentional effects emerged when the social interaction and social reward manipulations were removed. These results show that motivational incentives available during social exchanges affect later individual cognitive functioning, providing one of the first insights into why seemingly ambiguous social signals produce reliable and persistent attentional effects.

  18. Special issue: diagnostics of atmospheric pressure microplasmas

    Science.gov (United States)

    Bruggeman, Peter; Czarnetzki, Uwe; Tachibana, Kunihide

    2013-11-01

    In recent decades, a strong revival of non-equilibrium atmospheric pressure plasma studies has developed in the form of microplasmas. Microplasmas have typical scales of 1 mm or less and offer a very exciting research direction in the field of plasma science and technology as the discharge physics can be considerably different due to high collisionality and the importance of plasma-surface interaction. These high-pressure small-scale plasmas have a diverse range of physical and chemical properties. This diversity coincides with various applications including light/UV sources [1], material processing [2], chemical analysis [3], material synthesis [4], electromagnetics [5], combustion [6] and even medicine [7]. At atmospheric pressure, large scale plasmas have the tendency to become unstable due to the high collision rates leading to enhanced heating and ionization compared to their low-pressure counterparts. As low-pressure plasmas typically operate in reactors with sizes of tens of centimetres, scaling up the pressure to atmospheric pressure the size of the plasma reduces to typical sizes below 1 mm. A natural approach of stabilizing atmospheric pressure plasmas is thus the use of microelectrode geometries. Traditionally microplasmas have been produced in confined geometries which allow one to stabilize dc excited discharges. This stabilization is intrinsically connected to the large surface-to-volume ratio which enhances heat transfer and losses of charged and excited species to the walls. Currently challenging boundaries are pushed by producing microcavity geometries with dimensions of the order of 1 µm [8]. The subject of this special issue, diagnostics of microplasmas, is motivated by the many challenges in microplasma diagnostics in view of the complex chemistry and strong spatial (and even temporal) gradients of species densities and plasma properties. Atmospheric pressure plasmas have a very long history dating back more than 100 years, with early work of

We propose that neglect reflects deficits in the coding of saliency, control of spatial attention, and representation within an egocentric frame of reference, in conjunction with non-spatial deficits of reorienting, target detection, and arousal/vigilance. In contrast to theories that link spatial neglect to structural damage of specific brain regions, we argue that neglect is better explained by the physiological dysfunction of distributed cortical networks. The ventral lesions in right parietal, temporal, and frontal cortex that cause neglect directly impair non-spatial functions and hypoactivate the right hemisphere, inducing abnormalities in task-evoked activity and functional connectivity of a dorsal frontal-parietal network that controls spatial attention. The anatomy and right hemisphere dominance of neglect follows from the anatomy and laterality of the ventral regions that interact with the dorsal attention network. PMID:21692662

    Current behavior is influenced by events in the recent past. In visual attention, this is expressed in many varia- tions of priming effects. Here, we investigate color priming in a brief exposure digit-recognition task. Observers performed a masked odd-one-out singleton recognition taskwhere...... the target-color either repeated or changed between subsequent trials. Performance was measured by recognition accuracy over exposure durations. The purpose of the study was to replicate earlier findings of perceptual priming in brief displays and to model those results based on a Theory of Visual Attention...... by a simple four parameter model, where VSTM capacity and spatial biases of attention are ignored, or more fine-grained by a 10 parameter model that takes these aspects into account....

    Full Text Available The human attentional system can be subdivided into three functional networks of alerting, orienting, and executive control. Although these networks have been extensively studied in the visuospatial modality, whether the same mechanisms are deployed across different sensory modalities remains unclear. In this study we used the attention network test for visuospatial modality, in addition to two auditory variants with spatial and frequency manipulations to examine cross-modal correlations between network functions. Results showed that among the visual and auditory tasks the effects of executive control, but not effects of alerting and orienting were significantly correlated. These findings suggest that while alerting and orienting functions rely more upon modality specific processes, the executive control of attention coordinates complex behavior via supramodal mechanisms.

    Attention is not always directed to events in the external environment. On occasion our thoughts wander to people and places distant from the here and now. Sometimes, this lack of external attention can compromise ongoing task performance. In the current study we set out to understand the extent to which states of internal and external attention can be determined using pupillometry as an index of ongoing cognition. In two experiments we found that periods of slow responding were associated with elevations in the baseline pupil signal over three and a half seconds prior to a behavioural response. In the second experiment we found that unlike behavioural lapses, states of off-task thought, particularly those associated with a focus on the past and with an intrusive quality, were associated with reductions in the size of the pupil over the same window prior to the probe. These data show that both states of large and small baseline pupil size are linked to states when attention is not effectively focused on the external environment, although these states have different qualities. More generally, these findings illustrate that subjective and objective markers of task performance may not be equivalent and underscore the importance of developing objective indicators that can allow these different states to be understood.

    Full Text Available Bodily movement has long been employed as a foundation for cultivating mental skills such as attention, self-control or mindfulness, with recent studies documenting the positive impacts of mindful movement training, such as yoga and tai chi. A parallel mind-body connection has also been observed in many developmental disorders. We elaborate a spectrum of mindfulness by considering ADHD, in which deficient motor control correlates with impaired (disinhibited behavioral control contributing to defining features of excessive distractibility and impulsivity. These data provide evidence for an important axis of variation for wellbeing, in which skillful cognitive control covaries with a capacity for skillful movement. We review empirical and theoretical literature on attention, cognitive control, mind wandering, mindfulness and skill learning, endorsing a model of skilled attention in which motor plans, attention, and executive goals are seen as mutually co-defining aspects of skilled behavior that are linked by reciprocal inhibitory and excitatory connections. Thus, any movement training should engage higher-order inhibition and selection and develop a repertoire of rehearsed procedures that coordinate goals, attention and motor plans. However, we propose that mindful movement practice may improve the functional quality of rehearsed procedures, cultivating a transferrable skill of attention. We adopt Langer’s spectrum of mindful learning that spans from mindlessness to engagement with the details of the present task and contrast this with the mental attitudes cultivated in standard mindfulness meditation. We particularly follow Feldenkrais’ suggestion that mindful learning of skills for organizing the body in movement might transfer to other forms of mental activity.

    This study investigated the use of robotic technology for promoting attention, communication and social skills in adolescents with autism spectrum disorder (ASD). Attention, communication and social skills were measured while participants played a memory card matching game (Face Match) using (a) a humanoid robot, (b) a Smart Board and (c) playing cards. Three participants with ASD and three with other cognitive impairments were recruited from a secondary school with a special needs unit. Participants were paired such that one of each pair had a diagnosis of ASD and Face Match was played in these pairs for ∼15 min, with a game organizer present. On 3 separate days, video recordings were made as the participants played Face Match; a different game mode (robot, Smart Board, playing cards) was used each day. A system for categorizing attention, communication and social skills was developed that described 16 subcategories of interactions and intra-actions. In general, participants with ASD showed highly individualized patterns of behaviour in the three different modes. However, repetitive behaviour was reduced in participants with ASD when using both the robot and the Smart Board compared with playing cards. We show that it is feasible to use a robot to assist teaching of social skills to adolescents with ASD, but suggest that the robot features could be further explored and utilized.

    Fresh fruit is important for a healthy diet. However, because of their seasonal production, regional specific cultivation, and perishable nature, it is essential to develop preservation technologies to extend the postharvest shelf life of fresh fruits. Climacteric fruit adopt spoilage because of ethylene, a key hormone associated with the ripening process. Therefore, controlling ethylene activity by following safe and effective approaches is a key to extend the postharvest shelf life of fruit. In this review, ethylene control technologies will be discussed aiming for the need of developing more innovative and effective approaches. The biosynthesis pathway will be given first. Then, the technologies determining the postharvest shelf life of climacteric fruit will be described with special attention to the latest and significant published works in this field. Special attention is given to 1-methylcyclopropene (1-MCP), which is effective in fruit preservation technologies. Finally, the encapsulation technology to improve the stability of 1-MCP will be proposed, using a potential encapsulation agent of 1-MCP, calixarene.

    Obesity is a growing health problem, but most people find dieting unsuccessful. Three studies examine possible reasons for the difficulty and the extent to which dieting-related reductions in cognitive function are associated with mood and well-being. In Study One, 49 female dieters were compared with a control group of 31 matched non-dieters on measures of well-being, mood, eating behaviour (Dutch Eating Behaviour Questionnaire), and attention. Study Two examined two measures of restraint to examine why previous studies find high restrainers are prone to react to emotion. Study Three experimentally manipulated mood using music and the standard Velten Induction Procedure to examine attention in restrainers and emotional eaters. Dieting was found to be associated with deficits in sustained attention. This finding was further supported by the demonstration of a significant impairment in performance following a negative mood induction in high emotional eaters whereas high restrainers were relatively unaffected by the mood challenge. We suggest that different aspects of eating behaviour have dissociable effects on cognitive-affective function. Trait tendencies to restrained eating are associated with attentional deficits, but are not further affected by mood disruption. It is the long-term tendency to eat when emotional that combines with current emotional state to trigger cognitive deficits.

    Mandatory predonation reading materials inform donors about risk factors for transmissible disease, possible complications of donation and changes to the donation process. We aimed to assess the attention to predonation reading materials and factors which may affect attention. A national survey in 2008 of 18,108 blood donors asked about self-assessed attention to reading the materials. In face-to-face interviews, 441 donors completed additional questions about reading the materials and a literacy test. Qualitative interviews of 27 donors assessed their approach to reading. In the national survey, most of the first-time donors said they read all or most of the materials (90.9% first-time vs. 57.6% repeat donors, P reading them carefully (P read materials carefully, skimmed or did not read, most knew that donors are informed of positive transmissible disease test results (97.1%, 95.5, 98.0 P > 0.05), but fewer recalled seeing the definition of sex (77.2%, 56.9, 24.2 P read materials carefully, skimmed or did not read were compared (P > 0.05). Qualitative interviews showed that donors are reluctant to read any more than necessary and decide based on perceived importance or relevance. Attention to predonation reading materials tends to be better among first-time donors. The effectiveness is limited by low motivation to read, especially for repeat donors, as well as poor literacy. © 2015 International Society of Blood Transfusion.

    Full Text Available Abstract Background The aim of the study was to assess the attentional requirements of steady state treadmill walking in human subjects using a dual task paradigm. The extent of decrement of a secondary (cognitive RT task provides a measure of the attentional resources required to maintain performance of the primary (locomotor task. Varying the level of difficulty of the reaction time (RT task is used to verify the priority of allocation of attentional resources. Methods 11 healthy adult subjects were required to walk while simultaneously performing a RT task. Participants were instructed to bite a pressure transducer placed in the mouth as quickly as possible in response to an unpredictable electrical stimulation applied on the back of the neck. Each subject was tested under five different experimental conditions: simple RT task alone and while walking, recognition RT task alone and while walking, walking alone. A foot switch system composed of a pressure sensitive sensor was placed under the heel and forefoot of each foot to determine the gait cycle duration. Results Gait cycle duration was unchanged (p > 0.05 by the addition of the RT task. Regardless of the level of difficulty of the RT task, the RTs were longer during treadmill walking than in sitting conditions (p 0.05 was found between the attentional demand of the walking task and the decrement of performance found in the RT task under varying levels of difficulty. This finding suggests that the healthy subjects prioritized the control of walking at the expense of cognitive performance. Conclusion We conclude that treadmill walking in young adults is not a purely automatic task. The methodology and outcome measures used in this study provide an assessment of the attentional resources required by walking on the treadmill at a steady state.

The first section on Energy and Economics discusses the role of transportation energy and vehicle markets on a national (and even international) scale. For example, Figures 12 through 14 discuss the connections between global oil prices and U.S. GDP, and Figures 21 and 22 show U.S. employment in the automotive sector. The following section examines Light-Duty Vehicle use, markets, manufacture, and supply chains. Figures 24 through 51 offer snapshots of major light-duty vehicle brands in the U.S. and Figures 56 through 64 examine the performance and efficiency characteristics of vehicles sold. The discussion of Medium and Heavy Trucks offers information on truck sales (Figures 73 through 75) and fuel use (Figures 78 through 81). The Technology section offers information on alternative fuel vehicles and infrastructure (Figures 84 through 95), and the Policy section concludes with information on recent, current, and near-future Federal policies like the Corporate Average Fuel Economy standard (Figures 106 through 110). In total, the information contained in this report is intended to communicate a fairly complete understanding of U.S. highway transportation energy through a series of easily digestible nuggets.

    Many adults who stutter presenting for speech treatment experience social anxiety disorder. The presence of mental health disorders in adults who stutter has been implicated in a failure to maintain speech treatment benefits. Contemporary theories of social anxiety disorder propose that the condition is maintained by negative cognitions and information processing biases. Consistent with cognitive theories, the probe detection task has shown that social anxiety is associated with an attentional bias to avoid social information. This information processing bias is suggested to be involved in maintaining anxiety. Evidence is emerging for information processing biases being involved with stuttering. This study investigated information processing in adults who stutter using the probe detection task. Information processing biases have been implicated in anxiety maintenance in social anxiety disorder and therefore may have implications for the assessment and treatment of stuttering. It was hypothesized that stuttering participants compared with control participants would display an attentional bias to avoid attending to social information. Twenty-three adults who stutter and 23 controls completed a probe detection task in which they were presented with pairs of photographs: a face displaying an emotional expression-positive, negative or neutral-and an everyday household object. All participants were subjected to a mild social threat induction being told they would speak to a small group of people on completion of the task. The stuttering group scored significantly higher than controls for trait anxiety, but did not differ from controls on measures of social anxiety. Non-socially anxious adults who stutter did not display an attentional bias to avoid looking at photographs of faces relative to everyday objects. Higher scores on trait anxiety were positively correlated with attention towards photographs of negative faces. Attentional biases as assessed by the probe

    This review focuses on covert attention and how it alters early vision. I explain why attention is considered a selective process, the constructs of covert attention, spatial endogenous and exogenous attention, and feature-based attention. I explain how in the last 25 years research on attention has characterized the effects of covert attention on spatial filters and how attention influences the selection of stimuli of interest. This review includes the effects of spatial attention on discriminability and appearance in tasks mediated by contrast sensitivity and spatial resolution; the effects of feature-based attention on basic visual processes, and a comparison of the effects of spatial and feature-based attention. The emphasis of this review is on psychophysical studies, but relevant electrophysiological and neuroimaging studies and models regarding how and where neuronal responses are modulated are also discussed.
