  1. Negation, Including, Gradual Oblivion: State Strategies On Soviet Heritage In Georgia, Armenia And Azerbaijan

    Directory of Open Access Journals (Sweden)

    A. A. Tokarev

    2017-01-01

    Full Text Available In the year of 100th anniversary of the October Revolution, the author turns to the question of the Soviet heritage influence on nation- and state-building processes in three countries of the South Caucasus –Azerbaijan,ArmeniaandGeorgia. The article postulates clear differences between the study of postcolonialism and the post-Soviet space, and therefore the author presents his own operationalization of the "imperial heritage" study. The countries of the South Caucasus are compared based on the following criteria: a number of ethnic Russians as the main constituent of the Soviet people living in the country; a status of the Russian language; national symbols (statutes, architecture, Soviet state symbols, the hierarchy of military ranks, and political practices (functioning of the party systems, type of sovereignty, degree of freedom of speech and political competition. StudyingAzerbaijan,ArmeniaandGeorgiadifferently coming out of theUSSRand using the disintegration of theUSSRto construct their national narratives in accordance with their own ideas about the ways of development, the author finds a repetition of the Soviet system elements. Each of the states demonstrates a unique combination of “post-Soviet Soviet” phenomena. The difference lies in the ratio between pro-Soviet and anti-Soviet elements. Azerbaijanseems to maintain a pro-Soviet narrative more than the others. It inherited the Soviet cult of personality and combined this practice with a completely non-Soviet (Eastern tradition of political dynasties covered by the election system. The Armenian political tradition includes reference to Soviet Armenia as theSecondRepublic, which distinguishes the country from the neighbors who consider themselves to be the successors of the democratic republics that emerged during the Civil War inRussia. Despite competitive elections and free media, the Armenian leadership seeks to establish a political system with a single dominant party and

  2. Including a learner with physical disabilities: stressful for teachers?

    Full Text Available Learners with physical disabilities have been entering mainstream schools for some years now. Whereas early research on inclusive education necessitated a strong focus on the needs of the learners, there has also been a recent interest in the role of the teachers in inclusive education. By adopting constructivism as the paradigm for inquiry a study was undertaken to establish the stress factors for teachers who have to include a learner with a physical disability in their mainstream classes. The rationale for the study is threefold: i Learners with physical disabilities are entering mainstream schools increasingly, ii it is often assumed that inclusive education is too stressful for teachers to cope with, and iii related research has shown that increased contact with individuals with disabilities has a positive effect on attitudes towards individuals with disabilities. In accordance with the dialectical methodology of constructivism, the Teacher Stress and Coping Questionnaire and in-depth interviews were utilised to establish the stress factors and the extent of the stress factors that may be present. The aim of the constructivist inquiry process is to promote understanding and reconstruction. In this article the quantitative results indicate overall low or non-existent levels of stress in teachers who have to include a learner with a physical disability, and the results therefore contribute to our understanding of this situation. The qualitative results reconstruct the meanings that these teachers attach to the inclusion of a learner with a physical disability and reveal some albeit limited concerns about the communication processes between parents and teachers and a perceived lack of pre-service training.

    2016-12-01

    People with disabilities are largely absent from mainstream health research. Exclusion of people with disabilities may be explicit, attributable to poorly justified exclusion criteria, or implicit, attributable to inaccessible study documents, interventions, or research measures. Meanwhile, people with disabilities experience poorer health, greater incidence of chronic conditions, and higher health care expenditure than people without disabilities. We outline our approach to "accessible research design"-research accessible to and inclusive of people with disabilities. We describe a model that includes 3 tiers: universal design, accommodations, and modifications. Through our work on several large-scale research studies, we provide pragmatic examples of accessible research design. Making efforts to include people with disabilities in public health, epidemiological, and outcomes studies will enhance the interpretability of findings for a significant patient population.

  11. Music for All: Including young people with intellectual disability in a university environment.

    Science.gov (United States)

    Rickson, Daphne; Warren, Penny

    2017-01-01

    We investigated a continuing education course in creative music making, initiated to promote the inclusion of young people with intellectual disability in a university setting. Despite organizers' attempts to foster diversity within the student cohort, enrolments were almost exclusively from students who had intellectual disability. Being in the university environment, and in a place of higher learning, seemed to be valued by some. However, students' main focus was on group musicking in a dedicated music room rather than interacting with the wider university community. Those who did not identify as disabled believed it was important to continue to address the barriers to wider inclusion. While acknowledging the risks around mediating the social interactions of young people with intellectual disability, we argue that future courses should include activities specifically designed to bring them to classes with typical students and to the wider activities of the university.

    Over the past 20 years, programmers have embraced dynamically-typed programming languages. By now, they have also come to realize that programs in these languages lack reliable type information for software engineering purposes. Gradual typing addresses this problem; it empowers programmers to annotate an existing system with sound type information on a piecemeal basis. This paper presents an implementation of a gradual type system for a full-featured class-based language as well as a novel p...

    Mutations or structural genomic alterations of the X-chromosomal gene ARHGEF9 have been described in male and female patients with intellectual disability. Hyperekplexia and epilepsy were observed to a variable degree, but incompletely described. Here, we expand the phenotypic spectrum of ARHGEF9 by describing a large Ethiopian-Jewish family with epilepsy and intellectual disability. The four affected male siblings, their unaffected parents and two unaffected female siblings were recruited and phenotyped. Parametric linkage analysis was performed using SNP microarrays. Variants from exome sequencing in two affected individuals were confirmed by Sanger sequencing. All affected male siblings had febrile seizures from age 2-3 years and intellectual disability. Three developed afebrile seizures between age 7-17 years. Three showed focal seizure semiology. None had hyperekplexia. A novel ARHGEF9 variant (c.967G>A, p.G323R, NM_015185.2) was hemizygous in all affected male siblings and heterozygous in the mother. This family reveals that the phenotypic spectrum of ARHGEF9 is broader than commonly assumed and includes febrile seizures and focal epilepsy with intellectual disability in the absence of hyperekplexia or other clinically distinguishing features. Our findings suggest that pathogenic variants in ARHGEF9 may be more common than previously assumed in patients with intellectual disability and mild epilepsy.

    Claudia P. Serrano R

    2011-07-01

    Full Text Available Objective: to explore the factors enabling or hindering the implementation of inclusive education policies for the disabled population of Bucaramanga. Methodology: a descriptive study, involving representatives from governmental agencies (EG, members of the faculty boards of educational institutions (DIE and guardians of disabled individuals (APSD. Physical, social, and political obstacles and facilitating factors that could potentially determine the implementation of these policies were analyzed. Data was collected through interviews. Results: there was a total of 2, 32, and 34 participants from the EG, DIE, and APSD groups respectively. Identified obstacles included: lack of strategies to support educational institutions, poor or limited teacher training, high tuition fees, and negative attitude towards disability. The facilitating factors included: availability of places, inclusion of this issue in the political agenda, and desire of the disabled individuals’ families to provide them with education. Discussion: These findings provide useful information for further research on this issue and show how action has been taken, as well as how urgent it is to establish a direct relationship between academia and the public sector to propose strategies for assessing and modifying these policies.

  2. Cerebellar abnormalities contribute to disability including cognitive impairment in multiple sclerosis.

    Directory of Open Access Journals (Sweden)

    Katrin Weier

    Full Text Available The cerebellum is known to be involved not only in motor but also cognitive and affective processes. Structural changes in the cerebellum in relation to cognitive dysfunction are an emerging topic in the field of neuro-psychiatric disorders. In Multiple Sclerosis (MS cerebellar motor and cognitive dysfunction occur in parallel, early in the onset of the disease, and the cerebellum is one of the predilection sites of atrophy. This study is aimed at determining the relationship between cerebellar volumes, clinical cerebellar signs, cognitive functioning and fatigue in MS. Cerebellar volumetry was conducted using T1-weighted MPRAGE magnetic resonance imaging of 172 MS patients. All patients underwent a clinical and brief neuropsychological assessment (information processing speed, working memory, including fatigue testing. Patients with and without cerebellar signs differed significantly regarding normalized cerebellar total volume (nTCV, normalized brain volume (nBV and whole brain T2 lesion volume (LV. Patients with cerebellar dysfunction likewise performed worse in cognitive tests. A regression analysis indicated that age and nTCV explained 26.3% of the variance in SDMT (symbol digit modalities test performance. However, only age, T2 LV and nBV remained predictors in the full model (r(2 = 0.36. The full model for the prediction of PASAT (Paced Auditory Serial Addition Test scores (r(2 = 0.23 included age, cerebellar and T2 LV. In the case of fatigue, only age and nBV (r(2 = 0.17 emerged as significant predictors. These data support the view that cerebellar abnormalities contribute to disability, including cognitive impairment in MS. However, this contribution does not seem to be independent of, and may even be dominated by wider spread MS pathology as reflected by nBV and T2 LV.

    Students with disabilities in the tertiary education sector are more than a just a phenomenon, they are a reality. In general, little attention is devoted to their needs despite the fact that they need more care and attention. This paper, through a case study at the University of Mauritius, sought to answer some pertinent questions regarding students with disabilities. Does the University of Mauritius have sufficient facilities to support these students? Are students aware of existing facilities? What additional structures need to be put in place so that students with any form of disability are neither victimised, nor their education undermined? Are there any local laws about students with disabilities in higher education? To answer these questions and others, an online questionnaire was sent to 500 students and the responses were then analysed and discussed. The response rate was 24.4% which showed that students were not reticent to participate in this study. Our survey revealed that most students were not aware of existing facilities and were often neglected in terms of supporting structures and resources. ICT facilities were found to be the best support that is provided at the University of Mauritius. The right legal framework for tertiary education was also missing. Ideally, students with disabilities should have access to special facilities to facilitate their learning experiences at tertiary institutions. Awareness about existing facilities must also be raised in order to offer equal opportunities to them and to enable a seamless inclusion.

    2012-01-01

    This article presents the results of a survey carried out on leading periodicals in the areas of Ergonomics, Physiotherapy and Occupational Therapy, the aim of which was to identify scientific publications on the inclusion at work of people with disabilities. The survey of articles published on this topic in the following journals was conducted in December 2010: Applied Ergonomics, Ergonomics, the International Journal of Industrial Ergonomics, Disability and Rehabilitation, and the Journal of Occupational Rehabilitation. The survey covered issues published between 2000 and 2010 and was conducted electronically using the CAPES Periodicals Portal. To collect the articles, it was necessary to check the articles published in each of the issues of each volume of these periodicals. This is how the articles on the topic in question were found. There were 27 articles on the topic of inclusion at work of people with disabilities, of which 13 were published in the Journal of Occupational Rehabilitation and 12 in Disability and Rehabilitation. Thus, it is clear that the issue in question is still a subject that is seldom dealt with in these publications and it is noted that only two articles were published in Ergonomics journals in this period, thus confirming the paucity of scientific publications on this subject.

    To review gradual snare occlusion for the management of complex or recurrent graft infection. Medical records of patients treated with gradual snare occlusion following graft infection were reviewed for indication for operation, type of bypass and graft material used. In addition, infecting organism, grade of infection (Szilágyi) and outcome were recorded. Four femoropopliteal, two extra-anatomic (axillofemoral) and aortobifemoral bypasses were included in this study. All had chronic infection (Szilágyi grade III) with onset of 4 to 24 months and two of which were recurrent. The causative organisms were coagulase-negative staphylococci, Staphylococcus epidermidis and methicillin-resistant Staphylococcus aureus in three patients, with no organism isolated in the remaining cases. There was no loss of limb following gradual snare occlusion but there was only one death due to aortic stump rupture 2 weeks later. Gradual snare occlusion is an alternative for the management of chronic or recurrent graft infection. Copyright 1999 Harcourt Publishers Ltd.

  8. Using assistive technology adaptations to include students with learning disabilities in cooperative learning activities.

    Science.gov (United States)

    Bryant, D P; Bryant, B R

    1998-01-01

    Cooperative learning (CL) is a common instructional arrangement that is used by classroom teachers to foster academic achievement and social acceptance of students with and without learning disabilities. Cooperative learning is appealing to classroom teachers because it can provide an opportunity for more instruction and feedback by peers than can be provided by teachers to individual students who require extra assistance. Recent studies suggest that students with LD may need adaptations during cooperative learning activities. The use of assistive technology adaptations may be necessary to help some students with LD compensate for their specific learning difficulties so that they can engage more readily in cooperative learning activities. A process for integrating technology adaptations into cooperative learning activities is discussed in terms of three components: selecting adaptations, monitoring the use of the adaptations during cooperative learning activities, and evaluating the adaptations' effectiveness. The article concludes with comments regarding barriers to and support systems for technology integration, technology and effective instructional practices, and the need to consider technology adaptations for students who have learning disabilities.

    2015-11-01

    Full Text Available At present, quality of life and self-determination begin to position itself as a key axis in interventions aimed at students with disabilities, motivating the interest of researchers and professionals to know their general well-being. This article evaluates the quality of life and self-determination of students with intellectual and developmental disabilities enrolled in regular schools. A case study methodology, descriptive-interpretative, is used through mixed data collection methods. The instruments used are Questionnaire for Assessment the Quality of Life in Teen Students (CCVA and ARC-INICO Scale for Assessment Self-Determination (for 14 students and interviews (for four teachers. A descriptive statistical analysis, contextualized by the extracted information from the interviews, was conducted. The results show high scores in different domains of quality of life, apart from emotional well-being, community inclusion and self-determination that are improvable. Adequate perception of students is observed about their ability to make decisions, choices and a good predisposition take control in different areas of their life. It is necessary to continue inquiring about the impact of educational environment, attitude and perception of teachers and the opportunities offered to students to act self-determined and increase their quality of life.

    The paper describes an iterative development process used to understand the suitability of different inclusive design evaluation tools applied into design practices. At the end of this process, a tool named Inclusive Design Advisor was developed, combining data related to design features of small appliances with ergonomic task demands, anthropometric data and exclusion data. When auditing a new design the tool examines the exclusion that each design feature can cause, followed by objective recommendations directly related to its features. Interactively, it allows designers or clients to balance design changes with the exclusion caused. It presents the type of information that enables designers and clients to discuss user needs and make more inclusive design decisions. Copyright © 2017. Published by Elsevier Ltd.

  13. The Gradual Evolution of Language

    Directory of Open Access Journals (Sweden)

    Michael C. Corballis

    2014-12-01

    Full Text Available Language is commonly held to be unique to humans, and to have emerged suddenly in a single “great leap forward” within the past 100,000 years. The view is profoundly anti-Darwinian, and I propose instead a framework for understanding how language might have evolved incrementally from our primate heritage. One major proposition is that language evolved from manual action, with vocalization emerging as the dominant mode late in hominin evolution. The second proposition has to do with the role of language as a means of communicating about events displaced in space and time from the present. Some have argued that mental time travel itself is unique to human, which might explain why language itself is uniquely human. I argue instead that mental time travel has ancient evolutionary origins, and gradually assumed narrative-like properties during the Pleistocene, when language itself began to take shape.

    Zink, A M; Wohlleber, E; Engels, H

    2014-01-01

    Fragile X syndrome (FXS) is one of the most common causes of intellectual disability/developmental delay (ID/DD), especially in males. It is caused most often by CGG trinucleotide repeat expansions, and less frequently by point mutations and partial or full deletions of the FMR1 gene. The wide...... clinical spectrum of affected females partly depends on their X-inactivation status. Only few female ID/DD patients with microdeletions including FMR1 have been reported. We describe 3 female patients with 3.5-, 4.2- and 9.2-Mb de novo microdeletions in Xq27.3-q28 containing FMR1. X-inactivation was random...

    Sermier Dessemontet, Rachel; Bless, Gérard

    2013-03-01

    This study aimed at assessing the impact of including children with intellectual disability (ID) in general education classrooms with support on the academic achievement of their low-, average-, and high-achieving peers without disability. A quasi-experimental study was conducted with an experimental group of 202 pupils from classrooms with an included child with mild or moderate ID, and a control group of 202 pupils from classrooms with no included children with special educational needs (matched pairs sample). The progress of these 2 groups in their academic achievement was compared over a period of 1 school year. No significant difference was found in the progress of the low-, average-, or high-achieving pupils from classrooms with or without inclusion. The results suggest that including children with ID in primary general education classrooms with support does not have a negative impact on the progress of pupils without disability.

    The aim of this paper is to present the results of the evaluation of the job of bricklayer in the construction industry to determine the profile of workers with disabilities who could perform this function and what adjustments are needed. The methods and techniques used in the field study were: direct observation of the activities and the environment, interviews with bricklayers on building sites, a video and photographic record of tasks being carried out to analyze the job of bricklayer, software resources were used. This study set out the disabilities most commonly caused by work accidents in the civil construction industry and simulated the conditions of the individuals to determine whether they could perform the activities of this function and what adaptations are needed. It was observed that workers with hearing impairments could perform activities without any change in the workplace and individuals who had had a leg or foot amputated need to use appropriate prostheses to perform the activities of the function. Thus, it was shown that the activity of professionals with experience in Ergonomics is essential since, by the activity of gathering data and analysing the physical, cognitive and organizational requirements of jobs and by collecting data on and analysing the functional capabilities of the worker with a disability, adaptations to jobs can be adequately defined.

    A spacecraft (8) includes a movable appendage such as solar panels (12) operated by a stepping motor (28) driven by pulses (311). In order to reduce vibration andor attitude error, the drive pulses are generated by a clock down-counter (312) with variable count ratio. Predetermined desired clock ratios are stored in selectable memories (314a-d), and the selected ratio (R) is coupled to a comparator (330) together with the current ratio (C). An up-down counter (340) establishes the current count-down ratio by counting toward the desired ratio under the control of the comparator; thus, a step change of solar panel speed never occurs. When a direction change is commanded, a flag signal generator (350) disables the selectable memories, and enables a further store (360), which generates a count ratio representing a very slow solar panel rotational rate, so that the rotational rate always slows to a low value before direction is changed. The principles of the invention are applicable to any movable appendage.

    Full Text Available Abstract Background Patient reported outcome measures (PROMs are self-report measures of health status increasingly promoted for use in healthcare quality improvement. However people with low literacy skills or learning disabilities may find PROMs hard to complete. Our study investigated stakeholder views on the accessibility and use of PROMs to develop suggestions for more inclusive practice. Methods Taking PROMs recommended for chronic obstructive pulmonary disease (COPD as an example, we conducted 8 interviews with people with low literacy skills and/or learning disabilities, and 4 focus groups with 20 health professionals and people with COPD. Discussions covered the format and delivery of PROMs using the EQ-5D and St George Respiratory Questionnaire as prompts. Thematic framework analysis focused on three main themes: Accessibility, Ease of Use, and Contextual factors. Results Accessibility included issues concerning the questionnaire format, and suggestions for improvement included larger font sizes and more white space. Ease of Use included discussion about PROMs’ administration. While health professionals suggested PROMs could be completed in waiting rooms, patients preferred settings with more privacy and where they could access help from people they know. Contextual Factors included other challenges and wider issues associated with completing PROMs. While health professionals highlighted difficulties created by the system in managing patients with low literacy/learning disabilities, patient participants stressed that understanding the purpose of PROMs was important to reduce intimidation. Conclusions Adjusting PROMs’ format, giving an explicit choice of where patients can complete them, and clearly conveying PROMs’ purpose and benefit to patients may help to prevent inequality when using PROMs in health services.

    Red abalone (Haliotis rufescens) nacre is a layered composite biomineral that contains crystalline aragonite tablets confined by organic layers. Nacre is intensely studied because its biologically controlled microarchitecture gives rise to remarkable strength and toughness, but the mechanisms leading to its formation are not well understood. Here we present synchrotron spectromicroscopy experiments revealing that stacks of aragonite tablet crystals in nacre are misoriented with respect to each other. Quantitative measurements of crystal orientation, tablet size, and tablet stacking direction show that orientational ordering occurs not abruptly but gradually over a distance of 50 {micro}m. Several lines of evidence indicate that different crystal orientations imply different tablet growth rates during nacre formation. A theoretical model based on kinetic and gradual selection of the fastest growth rates produces results in qualitative and quantitative agreement with the experimental data and therefore demonstrates that ordering in nacre is a result of crystal growth kinetics and competition either in addition or to the exclusion of templation by acidic proteins as previously assumed. As in other natural evolving kinetic systems, selection of the fastest-growing stacks of tablets occurs gradually in space and time. These results suggest that the self-ordering of the mineral phase, which may occur completely independently of biological or organic-molecule control, is fundamental in nacre formation.

  10. Implications of a fossil stickleback assemblage for Darwinian gradualism.

    Bell, M A

    2009-11-01

    Darwin postulated that a complete fossil record would contain numerous gradual transitions between ancestral and descendant species, but 150 years after publication of The Origin of Species, few such transitions have materialized. The fossil stickleback Gasterosteus doryssus and the deposit in which it occurs provide excellent conditions to detect such transitions. Abundant, well-preserved fossils occur in a stratigraphic setting with fine temporal resolution. The paleoecology of G. doryssus resembles the ecology of modern lakes that harbour the phenotypically similar three-spined stickleback Gasterosteus aculeatus. Gasterosteus aculeatus are primitively highly armoured, but G. doryssus comprised two contemporaneous biological species with relatively weak armour, including a near-shore, benthic feeder (benthic) and an offshore planktivore (limnetic). The benthic species expanded its range into the limnetic zone of the lake, where it apparently switched to planktivory and evolved reduced armour within c. 5000 years in response to directional selection. Although gradual evolution of mean phenotypes occurred, a single major gene caused much of evolutionary change of the pelvic skeleton. Thus, Darwin's expectation that transitions between species in the fossil record would be gradual was met at a fine time scale, but for pelvic structure, a well-studied trait, his expectation that gradual change would depend entirely on numerous, small, heritable differences among individuals was incorrect.

    Many studies have shown that molecular karyotyping is an effective diagnostic tool in individuals with developmental delay/intellectual disability. We report on a de novo interstitial 1q22q23.1 microdeletion, 1.6 Mb in size, detected in a patient with short stature, microcephaly, hypoplastic corpus callosum, cleft palate, minor facial anomalies, congenital heart defect, camptodactyly of the 4-5th fingers, and intellectual disability. Chromosomal microarray analysis revealed a 1.6-Mb deletion in the 1q22q23.1 region, arr[GRCh37] 1q22q23.1(155630752_157193893)×1. Real-time PCR analysis confirmed its de novo origin. The deleted region encompasses 50 protein-coding genes, including the morbid genes APOA1BP, ARHGEF2, LAMTOR2, LMNA, NTRK1, PRCC, RIT1, SEMA4A, and YY1AP1. Although the unique phenotype observed in our patient can arise from the haploinsufficiency of the dosage-sensitive LMNA gene, the dosage imbalance of other genes implicated in the rearrangement could also contribute to the phenotype. Further studies are required for the delineation of the phenotype associated with this rare chromosomal alteration and elucidation of the critical genes for manifestation of the specific clinical features. © 2018 S.

    The gradual upgrading of NPP V1 Bohunice constitutes the most extensive reconstruction project to be performed in an operational WWER plant to date. It constitutes a milestone in Siemens co-operation on projects for WWERs to date and is an encouraging example for the successful combination of western and eastern safety cultures. During the runtime of this project Siemens learnt very much about the 'complete function' as well as the details of this WWER plant type. In contrast the Slovakian partners really gained a much better understanding for the western approach to ensure safety, for the most modern safety technology, in particular for instrumentation and control, and last but not least or advanced project management.

    Reseachers compare results with those in the chapter by Moore et al. (1980), who reached five main conclusions about the gradual phase: (1) the typical density of the soft X-ray emitting plasma is between 10 to the 11th power and 10 to the 12th power cm-3 for compact flares and between 10 to the 10th power and 10 to the 11th power cm-3 for a large-area flare; (2) cooling is by conduction and radiation in roughly equal proportions; (3) continual heating is needed in the decay phase of two-ribbon flares; (4) continual heating is probably not needed in compact events; (5) most of the soft-X-ray-emitting plasma results from chromospheric evaporation. The goal was to reexamine these problems with the data from the Solar Maximum Mission (SMM) and other supporting instruments as well as to take advantage of recent theoretical advances. SMM is capable of measuring coronal temperatures more accurately and with a better cadence than has been possible before. The SMM data set is also unique in that the complete transit of an active region was observed, with soft X-ray and UV images being taken every few minutes. Researcher's were therefore able to establish the pre-flare conditions of the region and see whether anything has changed as a result of the flare. The assumptions made in attempting to determine the required plasma parameters are described. The derived parameters for the five prime flares are presented, and the role of numerical simulations is discussed.

    We report an 11-year-old girl with mild intellectual disability, skeletal anomalies, congenital heart defect, myopia, and facial dysmorphisms including an extra incisor, cup-shaped ears, and a preauricular skin tag. Array comparative genomic hybridization analysis identified a de novo 4.5-Mb microdeletion on chromosome 14q24.2q24.3. The deleted region and phenotype partially overlap with previously reported patients. Here, we provide an overview of the literature on 14q24 microdeletions and further delineate the associated phenotype. We performed exome sequencing to examine other causes for the phenotype and queried genes present in the 14q24.2q24.3 microdeletion that are associated with recessive disease for variants in the non-deleted allele. The deleted region contains 65 protein-coding genes, including the ciliary gene IFT43. Although Sanger and exome sequencing did not identify variants in the second IFT43 allele or in other IFT complex A-protein-encoding genes, immunocytochemistry showed increased accumulation of IFT-B proteins at the ciliary tip in patient-derived fibroblasts compared to control cells, demonstrating defective retrograde ciliary transport. This could suggest a ciliary defect in the pathogenesis of this disorder. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

  18. GLUT1 deficiency syndrome as a cause of encephalopathy that includes cognitive disability, treatment-resistant infantile epilepsy and a complex movement disorder.

    Graham, John M

    2012-05-01

    Glucose transporter-1 (GLUT1) deficiency syndrome is caused by heterozygous mutations in the SLC2A1 gene, resulting in impaired glucose transport into the brain. It is characterized by a low glucose concentration in the cerebrospinal fluid (hypoglycorrhachia) in the absence of hypoglycemia, in combination with low to normal lactate in the cerebrospinal fluid (CSF). It often results in treatment-resistant infantile epilepsy with progressive developmental disabilities and a complex movement disorder. Recognizing GLUT1 deficiency syndrome is important, since initiation of a ketogenic diet can reduce the frequency of seizures and the severity of the movement disorder. There can be a considerable delay in diagnosing GLUT1 deficiency syndrome, and this point is illustrated by the natural history of this disorder in a 21-year-old woman with severe, progressive neurological disabilities. Her encephalopathy consisted of treatment-resistant seizures, a complex movement disorder, progressive intellectual disability, and deceleration of her head growth after late infancy. Focused evaluation at age 21 revealed GLUT1 deficiency caused by a novel heterozygous missence mutation in exon 7 (c.938C > A; p.Ser313Try) in SLC2A1 as the cause for her disabilities.

    Chrzanowski, M.; Latus, P.

    1993-01-01

    The most characteristic feature of progressive material deterioration in creep conditions Is its time-dependence. In structures this process comprises of three stages: 1. Incubation of a macroscopic defect at the time of First Crack Appearance (FCA); 2. Propagation of a macro-crack throughout the structural member at the Time of Member Failure (TMF); 3. Propagation of failure of consecutive structure members, leading to the Final Structure Collapse (FSC). The importance of a full analysis of a structure which comprises all above stages has been demonstrated previously. Corresponding times are denoted as t 1 , t 2 , t 3 respectively. Depending on many factors, like material properties, loading and supports, the ratio of t 1 /t 2 and t 2 /t 3 may vary significantly, and thus exhibiting a safety margin connected with damage propagation throughout the structure. However, the full analysis becomes very sophisticated since creep and damage evolutions law are often nonlinear ones, and analysis should include changing geometry of a structure. It was was found that the failure propagation in analysed structures appeared to be very sensitive to structures geometry and loading. The time ratio t 1 /t 3 depends on redundancy k (higher the redundancy lower the ratio), but structures collapse by local mechanisms. These mechanisms can be different depending on k. More decisive than redundancy is an overall configuration of loads and structure geometry because of different mechanism of final failure. So far, no general conclusion can be drawn, but the whole analysis resembles that of limit analysis for structures made of ideally plastic or elastic-plastic materials. Nevertheless it Is evident that full analysis of structures in creep conditions can significantly enhance the structures life-time expectation

Smokers with no strong preference for abrupt or gradual quitting were randomly assigned to quitting immediately (n=472), or to gradually reducing their cigarette consumption over 2 weeks and then quit (n=502). Smokers who strongly preferred to quit abruptly were instructed to do so immediately (n=2456), those who strongly preferred gradual were instructed to reduce their cigarette consumption over 2 weeks, then quit (n=1801). Follow-up was conducted 4 weeks after target quit dates. Those who preferred abrupt quitting were the most motivated to quit and the most confident in their ability to quit. At follow-up, quit rates were 16% in those who preferred abrupt cessation, 7% in those who preferred gradual cessation and 9% in those who had no preference (pmotivation to quit and confidence in ability to quit: those who had low levels of motivation or low levels of confidence were more likely to quit at follow-up if they preferred and used abrupt rather than gradual. In those who had no strong preference for either method, abrupt and gradual produced similar results. Those who preferred and used the abrupt method were more likely to quit than those who preferred and used the gradual method, in particular when they had low motivation and confidence.

    Braeckman Bart P

    2009-07-01

    Full Text Available Abstract Free-living flatworms ("Turbellaria" are appropriate model organisms to gain better insight into the role of stem cells in ageing and rejuvenation. Ageing research in flatworms is, however, still scarce. This is partly due to culture difficulties and the lack of a complete set of demographic data, including parameters such as median lifespan and age-specific mortality rate. In this paper, we report on the first flatworm survival analysis. We used the species Macrostomum lignano, which is an emerging model for studying the reciprocal influence between stem cells, ageing and rejuvenation. This species has a median lifespan of 205 ± 13 days (average ± standard deviation [SD] and a 90th percentile lifespan of 373 ± 32 days. The maximum lifespan, however, is more than 745 days, and the average survival curve is characterised by a long tail because a small number of individuals lives twice as long as 90% of the population. Similar to earlier observations in a wide range of animals, in M. lignano the age-specific mortality rate increases exponentially, but levels off at the oldest ages. To compare the senescence of M. lignano with that of other ageing models, we determined the mortality rate doubling time, which is 0.20 ± 0.02 years. As a result, we can conclude that M. lignano shows gradual senescence at a rate similar to the vertebrate ageing models Rattus norvegicus and Mus musculus. We argue that M. lignano is a suitable model for ageing and rejuvenation research, and especially for the role of stem cells in these processes, due to its accessible stem cell system and regeneration capacity, and the possibility of combining stem cell studies with demographic analyses.

  12. Economic analysis of gradual "social exhaustion" of waste management capacity.

    2013-12-01

    This article proposes to analyze the quantitative effects of a gradual physical and "social" exhaustion of a landfill site on an equilibrium waste management service. A gradual social exhaustion of a landfill is defined here as an upward shift of a "subjective factor" associated with the amount of waste, based on the plausible hypothesis that an individual will not accept excessive presence of landfilled waste. Physical exhaustion occurs when the absolute capacity of a landfill site decreases.

    2010-01-01

    Bilateral international tax treaties govern the host country taxation for the vast majority of the world’s foreign direct investment (FDI). Of particular interest is the fact that the tax rates used under these treaties are gradually falling although the treaties themselves do not specify any such reductions. Since there is no outside governing agency to redress treaty violations, such reductions must be both mutually beneficial and self-enforcing. Furthermore, the optimal tax rates must be l...

    To devise a technique for gradual occlusion of the caudal vena cava in dogs and determine effects of complete occlusion of the caudal vena cava. 8 mixed-breed hounds that weighed between 25 and 30 kg. Baseline evaluation of dogs included serum biochemical analyses and determination of glomerular filtration rate (GFR) with dynamic renal scintigraphy and plasma clearance analysis. An occluder was placed around the vena cava in the region cranial to the renal veins. The occluder was attached to a vascular access port. The vena cava was gradually occluded over 2 weeks. The GFR was measured every 2 weeks after surgery, and venograms were performed every 3 weeks after surgery. Blood samples were collected every 48 hours for the first week and then weekly thereafter to measure BUN and creatinine concentrations and activities of alanine transaminase, alkaline phosphatase, and creatinine kinase. Dogs were euthanatized 6 weeks after surgery, and tissues were submitted for histologic examination. The GFR and biochemical data were compared with baseline values. Gradual occlusion of the caudal vena cava was easily and consistently performed with this method, and adverse clinical signs were not detected. Formation of collateral vessels allowed overall GFR to remain constant despite a decrease in function of the left kidney. Measured biochemical values did not deviate from reference ranges. Gradual occlusion of the caudal vena cava may allow removal of adrenal gland tumors with vascular invasion that would otherwise be difficult or impossible to resect.

  19. LONG DURATION FLARE EMISSION: IMPULSIVE HEATING OR GRADUAL HEATING?

    Flare emissions in X-ray and EUV wavelengths have previously been modeled as the plasma response to impulsive heating from magnetic reconnection. Some flares exhibit gradually evolving X-ray and EUV light curves, which are believed to result from superposition of an extended sequence of impulsive heating events occurring in different adjacent loops or even unresolved threads within each loop. In this paper, we apply this approach to a long duration two-ribbon flare SOL2011-09-13T22 observed by the Atmosphere Imaging Assembly (AIA). We find that to reconcile with observed signatures of flare emission in multiple EUV wavelengths, each thread should be heated in two phases, an intense impulsive heating followed by a gradual, low-rate heating tail that is attenuated over 20–30 minutes. Each AIA resolved single loop may be composed of several such threads. The two-phase heating scenario is supported by modeling with both a zero-dimensional and a 1D hydrodynamic code. We discuss viable physical mechanisms for the two-phase heating in a post-reconnection thread.

    Full Text Available Introduction: The complexity of the nasal tip structures and the impact of surgical maneuvers make the prediction of the final outcome very difficult. Therefore, no single technique is enough to correct the several anatomical presentations, and adequate preoperative planning represents the basis of rhinoplasty. Objective: To present results of rhinoplasty, through the gradual surgical approach to nasal tip definition based on anatomical features, and to evaluate the degree of patient satisfaction after the surgical procedure. Methods: Longitudinal retrospective cohort study of the medical charts of 533 patients of both genders who underwent rhinoplasty from January of 2005 to January of 2012 was performed. Cases were allocated into seven groups: (1 no surgery on nasal tip; (2 interdomal breakup; (3 cephalic trim; (4 domal suture; (5 shield-shaped graft; (6 vertical dome division; (7 replacement of lower lateral cartilages. Results: Group 4 was the most prevalent. The satisfaction rate was 96% and revision surgery occurred in 4% of cases. Conclusion: The protocol used allowed the implementation of a gradual surgical approach to nasal tip definition with the nasal anatomical characteristics, high rate of patient satisfaction with the surgical outcome, and low rate of revision.

    The purpose of this project was to modify a smoking cessation program that uses computerized scheduled gradual reduction for use with adolescent smokers and to test the feasibility of this cessation approach in group support and minimal contact modalities. Utilizing a lesson plan approach with high school marketing students in five high schools and student survey feedback, the LifeSign program was modified to be an acceptable smoking cessation program for adolescent smokers. In the first study, 17 adolescent smokers used the modified program with seven associated weekly group support sessions. At the end of treatment, 29% had quit smoking, and over half of those who continued to smoke reduced their smoking rate by 50%. In the second study, the LifeSign for Teens program was evaluated with 18 adolescent smokers in a minimal contact format. At the end of treatment, 17% had quit smoking, and mean smoking rate reductions of 43% were found among those who continued smoking. At 1-year follow-up, all subjects who had quit at posttreatment reported continuous abstinence. The results of these two small trials suggest that a computerized scheduled gradual reduction approach may be an accepted and potentially efficacious approach for smoking cessation among adolescent smokers.

    In preterm infants, nasal continuous positive airway pressure (NCPAP) is widely used for treatment of respiratory distress syndrome. However, the strategies for successfully weaning infants off NCPAP are still not well defined and there remains considerable variation between the methods. The objective of this study is to determine whether gradual weaning of NCPAP pressure is more successful than sudden weaning off NCPAP to room air. A randomized controlled trial was conducted in a level 3 neonatal intensive care unit on 70 preterm neonates who were born between 26 and 32 weeks gestation and required NCPAP for at least 48 h. When infants were stable on NCPAP at 0.21 FiO 2 and 5 cm H 2 O positive end expiratory pressure, neonates were randomized to the gradual wean group (reduction in pressure by 1 cm every 8 h until 3 cm H 2 0 was reached) or to sudden wean group (one time NCPAP removal to room air). The primary outcome was a success at the first trial to wean to room air. Secondary outcomes were a number of trials, and weight and postmenstrual age (PMA) at the time of successful wean. Total number of days on NCPAP and length of stay (LOS) in the hospital were also compared between the groups. Of the 70 infants included in the study, 35 were randomized to sudden group and 33 infants to gradual group (2 excluded for protocol deviation). In sudden and gradual groups, 14 and 22 infants, respectively, were weaned successfully in the first attempt (P=0.03). The infants were successfully weaned at 32.7±1.7 weeks versus 33.1±2.4 weeks (P=0.39) PMA and at a weight of 1651±290 g versus 1589±398 g (P=0.46) in the sudden and gradual groups, respectively. The total number of days on NCPAP was 27±19 days versus 32±24 days (P=0.38) and LOS was 63±25 days versus 63±22 days (P=0.99) in the sudden and gradual groups, respectively. Gradual weaning method was more successful as compared to sudden weaning method in the initial trial off NCPAP. There was no

    Patients with Parkinson’s disease (PD) experience impaired initiation and inhibition of movements such as difficulty to start/stop walking. At single-joint level this is accompanied by reduced inhibition of antagonist muscle activity. While normal basal ganglia (BG) contributions to motor control include selecting appropriate muscles by inhibiting others, it is unclear how PD-related changes in BG function cause impaired movement initiation and inhibition at single-joint level. To further elucidate these changes we studied 4 right-hand movement tasks with fMRI, by dissociating activations related to abrupt movement initiation, inhibition and gradual movement modulation. Initiation and inhibition were inferred from ballistic and stepwise interrupted movement, respectively, while smooth wrist circumduction enabled the assessment of gradually modulated movement. Task-related activations were compared between PD patients (N = 12) and healthy subjects (N = 18). In healthy subjects, movement initiation was characterized by antero-ventral striatum, substantia nigra (SN) and premotor activations while inhibition was dominated by subthalamic nucleus (STN) and pallidal activations, in line with the known role of these areas in simple movement. Gradual movement mainly involved antero-dorsal putamen and pallidum. Compared to healthy subjects, patients showed reduced striatal/SN and increased pallidal activation for initiation, whereas for inhibition STN activation was reduced and striatal-thalamo-cortical activation increased. For gradual movement patients showed reduced pallidal and increased thalamo-cortical activation. We conclude that PD-related changes during movement initiation fit the (rather static) model of alterations in direct and indirect BG pathways. Reduced STN activation and regional cortical increased activation in PD during inhibition and gradual movement modulation are better explained by a dynamic model that also takes into account enhanced

    The lack of sustainability of the current Spanish energy system makes it necessary to study the adoption of alternative energy models. One of these is what is known as the hydrogen economy. In this paper, we aim to plan, for the case of Spain, an initial phase for transition to this energy model making use of the potential offered by each Spanish region. Specifically, the target pursued is to satisfy at least 15% of energy demand for transport by 2010 through renewable sources. We plan to attain this target gradually, establishing intermediate stages consisting of supplying 5 and 10% of the energy demand for transport by 2006 and 2008, respectively. The results obtained allow us to determine, for each region, the hydrogen production and consumption, the renewable energy sources used to obtain hydrogen and the transport requirements between regions.

    1982-03-01

    In order to obtain preliminary perspectives on fuel cladding deformation behavior under changing temperature and pressure conditions in a hypothetical loss-of-coolant accident of PWR, a Zircaloy-4 tube burst test was conducted in both air and 99.97% Ar atomospheres. The tubes were directly heated by AC-current and maintained at various temperatures, and pressurized gradually until rupture occurred. Rupture circumferential strains were generally larger in Ar gas than in air and attained a maximum around 1100 K in both atmospheres. Some tube tested in air produced axially-extended long balloons, which proved not to be explained by such properties or ideas as effect of cooling on strain rate, superplasticity, geometrical plastic instability and stresses generated by surface oxide layer. A cause of the long balloon may be obtained in the anisotropy of the material structure. But even a qualitative analysis based on this property can not be made due to insufficient data of the anisotropy. (author)

    BACKGROUND. An increase in total peripheral resistance (TPR) usually increases arterial wave reflection. During passive head-up tilt (HUT), however, arterial wave reflection decreases with increasing TPR. This study addressed whether arterial wave reflection gradually decreases during HUT. METHODS....... In 10 healthy volunteers (22-39 years, nine males), we recorded finger arterial pressures in supine position (0°), and 30°and 70°degrees HUT and active standing (90°). Aortic pressure was constructed from the finger pressure signal and hemodynamics were calculated. Arterial wave reflection...... from 0.9 dyn s/cm(5) at 0? to 1.2, 1.4 and 1.4 dyn s/cm(5) at 30°, 70° and 90° (p wave reflection...

    available clear Landsat 5–8 observations with the new Continuous Change Detection and Classification (CCDC) algorithm was very effective for illuminating vegetation trends. There are a number of potential challenges for assessing gradual changes, including atmospheric impacts, algorithm development and visualization of the changes. One of the biggest challenges for studying gradual change will be the lack of appropriate data for validating results and products.

    The use of radioisotopes and radiation is expanding in the fields of industries and medicine with a high potentiality of the application to environmental protection. The technology transfer on the use of isotopes and radiation is progressing in the framework of international cooperation. But the industry has maintained wait and see attitude on the commercialization of food irradiation. Such present features were the highlight in the 19th Japan Conference on Radiation and Radioisotopes held on November 14-16. 72 papers from 19 countries were presented and discussed in 13 sessions. The progress of accelerator technology has contributed to the expansion of radiation processing market. The importance of the application of isotopes and radiation to environmental protection has been gradually acknowledged, and the electron beam treatment of flue gas for acid rain abatement and the elimination of chlorinated ethylene from drinking water were discussed. Drastic change has not been seen in the climate of food irradiation, however there are several positive indicators which support the prediction of slow but steady progress in the commercialization of the process and the trade of irradiated foods.

    2002-12-01

    In 1996 the US construction industry comprised 5.4% of the annual US employment but accounted for 7.8% of nonfatal occupational injuries and illness and 9.7% of cases involving at least a day away from work. Information in the published literature on the disability arising from construction injuries is limited. The construction claims experience (n = 35,790) of a large workers' compensation insurer with national coverage was examined. The leading types and sources of disabling occupational morbidity in 1996 in the US construction industry were identified. Disability duration was calculated from indemnity payments data using previously published methods. The average disability duration for an injured construction worker was 46 days with a median of 0 days. The most frequently occurring conditions were low back pain (14.8%), foreign body eye injuries (8.5%), and finger lacerations (4.8%). Back pain also accounted for the greatest percentage of construction claim costs (21.3%) and disability days (25.5%). However, the conditions with the longest disability durations were sudden-onset injuries, including fractures of the ankle (median = 55 days), foot (42 days), and wrist (38 days). Same-level and elevated falls were the principal exposures for fractures of the wrist and ankle, whereas elevated falls and struck by incidents accounted for the majority of foot fractures. Manual materials handling activities were most often associated with low back pain disability. The results suggest that these most disabling injuries can be addressed by increasing primary prevention resources in slips and falls and exposures related to injuries of sudden-onset as well as in reducing manual materials handling and other exposures associated with more gradual-onset injuries.

    The United States invests billions of taxpayer dollars each year into foreign assistance programs that foster international diplomacy and development directed toward improving the quality of life for people around the world. These programs develop economies and combat poverty, promote democracy and governance, build new infrastructure, advance and protect human rights, among other development goals. The United States cannot effectively accomplish the goals of foreign assistance programs unless it undertakes measures to ensure that the programs are accessible to and inclusive of people with disabilities. The United States has been a leader in advancing the rights of people with disabilities and must continue to promote disability rights through its international development work. Overseas economic development will not be successful unless people with disabilities are included. Because of the significant number of people with disabilities in developing countries, if they are not included, the very economic growth the United States is trying to foster will be hindered. The goals of democracy and governance programs cannot be achieved without the inclusion of people with disabilities. In many countries, domestic law contains blatant discriminatory provisions for people with disabilities that undermine access to justice and full participation in society. The provisions that discriminate against people with disabilities include arbitrary exclusions in electoral codes, sweeping plenary guardianship laws with no due-process protections, discriminatory banking practices, and inaccessible court proceedings. National disability legal frameworks remain underdeveloped throughout the world. Copyright © 2012. Published by Elsevier Inc.

  14. Gradually Increased Training Intensity Benefits Rehabilitation Outcome after Stroke by BDNF Upregulation and Stress Suppression

    2014-01-01

    Full Text Available Physical training is necessary for effective rehabilitation in the early poststroke period. Animal studies commonly use fixed training intensity throughout rehabilitation and without adapting it to the animals' recovered motor ability. This study investigated the correlation between training intensity and rehabilitation efficacy by using a focal ischemic stroke rat model. Eighty male Sprague-Dawley rats were induced with middle cerebral artery occlusion/reperfusion surgery. Sixty rats with successful stroke were then randomly assigned into four groups: control (CG, n=15, low intensity (LG, n=15, gradually increased intensity (GIG, n=15, and high intensity (HG, n=15. Behavioral tests were conducted daily to evaluate motor function recovery. Stress level and neural recovery were evaluated via plasma corticosterone and brain-derived neurotrophic factor (BDNF concentration, respectively. GIG rats significantly (P<0.05 recovered motor function and produced higher hippocampal BDNF (112.87 ± 25.18 ng/g. GIG and LG rats exhibited similar stress levels (540.63 ± 117.40 nM/L and 508.07 ± 161.30 nM/L, resp., which were significantly lower (P<0.05 than that (716.90 ± 156.48 nM/L of HG rats. Training with gradually increased intensity achieved better recovery with lower stress. Our observations indicate that a training protocol that includes gradually increasing training intensity should be considered in both animal and clinical studies for better stroke recovery.

    Campomelic dysplasia and acampomelic campomelic dysplasia (ACD) are allelic disorders due to heterozygous mutations in or around SOX9. Translocations and deletions involving the SOX9 5' regulatory region are rare causes of these disorders, as well as Pierre Robin sequence (PRS) and 46,XY gonadal dysgenesis. Genotype-phenotype correlations are not straightforward due to the complex epigenetic regulation of SOX9 expression during development. We report a three-generation pedigree with a novel ∼1 Mb deletion upstream of SOX9 and including KCNJ2 and KCNJ16, and ascertained for dominant transmission of PRS. Further characterization of the family identified subtle appendicular anomalies and a variable constellation of axial skeletal features evocative of ACD in several members. Affected males showed learning disability. The identified deletion was smaller than all other chromosome rearrangements associated with ACD. Comparison with other reported translocations and deletions involving this region allowed further refining of genotype-phenotype correlations and an update of the smallest regions of overlap associated with the different phenotypes. Intrafamilial variability in this pedigree suggests a phenotypic continuity between ACD and PRS in patients carrying mutations in the SOX9 5' regulatory region. © 2015 Wiley Periodicals, Inc.

  17. Gradual reintroduction of oxygen reduces reperfusion injury in cat stomach

    Perry, M.A.; Wadhwa, S.S.

    1988-01-01

    Recent studies have shown that oxygen-derived free radicals are responsible for a major portion of ischemia-reperfusion injury in the stomach. The oxygen radicals are produced during perfusion when oxygen delivery to the tissue increases. In the present study the authors investigate the effect on mucosal injury of regulating the rate of reintroduction of oxygen to the stomach after ischemia. Local gastric ischemia was achieved by reducing celiac artery pressure to 30 mmHg for 1 h. Ischemic injury was assessed by measuring the loss of 51 Cr-labeled red blood cells across the gastric mucosa. Mucosal blood loss was negligible before and during the ischemia period but increased during reperfusion. When blood flow to the stomach was gradually returned to normal after ischemia, the mucosal blood loss was reduced. If the stomach was vascularly perfused with low Po 2 blood for 1 h after ischemia before being returned to normal arterial perfusion, the mucosal blood loss was also reduced. When the stomach was made hypoxemic for 1 h rather than ischemic by perfusing the vasculature with low Po 2 blood then reperfused with normoxic blood, there was very little mucosal bleeding. The data indicate that gastric mucosal bleeding after ischemia is reduced if the tissue is returned slowly to a normal Po 2 . These findings support the concept that reperfusion injury is due largely to the production of oxygen radicals. The low level of injury produced by hypoxemia indicates that hypoxia per se makes only a minor contribution to reperfusion injury in the stomach

  20. New description of gradual substitution of graft by bone tissue including biomechanical and structural effects, nutrients supply and consumption

    Science.gov (United States)

    Lu, Yanfei; Lekszycki, Tomasz

    2018-03-01

    A new description of graft substitution by bone tissue is proposed in this work. The studied domain is considered as a continuum model consisting of a mixture of the bone tissue and the graft material. Densities of both components evolve in time as a result of cellular activity and biodegradation. The proposed model focuses on the interaction between the bone cell activity, mechanical stimuli, nutrients supply and scaffold microstructure. Different combinations of degradation rate and stiffness of the graft material were examined by numerical simulation. It follows from the calculations that the degradation rate of the scaffold should be tuned to the synthesis/resorption rate of the tissue, which are dependent among the others on scaffold porosity changes. Simulation results imply potential criteria to choose proper bone substitute material in consideration of degradation rate, initial porosity and mechanical characteristics.

    This Article argues that the practice of holding so many adjudicative proceedings related to disability in private settings (e.g., guardianship, special education due process, civil commitment, and social security) relative to our strong normative presumption of public access to adjudication may cultivate and perpetuate stigma in contravention of the goals of inclusion and enhanced agency set forth in antidiscrimination laws. Descriptively, the law has a complicated history with disability--initially rendering disability invisible; later, underwriting particular narratives of disability synonymous with incapacity; and, in recent history, promoting the full socio-economic visibility of people with disabilities. The Americans with Disabilities Act (ADA), the marquee civil rights legislation for people with disabilities (about to enter its twenty-fifth year), expresses a national approach to disability that recognizes the role of society in its construction, maintenance, and potential remedy. However, the ADA’s mission is incomplete. It has not generated the types of interactions between people with disabilities and nondisabled people empirically shown to deconstruct deeply entrenched social stigma. Prescriptively, procedural design can act as an "ntistigma agent"to resist and mitigate disability stigma. This Article focuses on one element of institutional design--public access to adjudication--as a potential tool to construct and disseminate counter-narratives of disability. The unique substantive focus in disability adjudication on questions of agency provides a potential public space for the negotiation of nuanced definitions of disability and capacity more reflective of the human condition.

    Disability retirement may increase as the work force ages, but there is little information on factors associated with retirement because of disability. This is the first prospective population-based study of predictors of disability retirement including information on workplace, socioeconomic, behavioral, and health-related factors. The subjects were 1038 Finnish men who were enrolled in the Kuopio Ischemic Heart Disease Risk Factor Study, who were 42, 48, 54, or 60 years of age at the beginning of the study, and who participated in a 4-year follow-up medical examination. Various job characteristics predicted disability retirement. Heavy work, work in uncomfortable positions, long workhours, noise at work, physical job strain, musculoskeletal strain, repetitive or continuous muscle strain, mental job strain, and job dissatisfaction were all significantly associated with the incidence of disability retirement. The ability to communicate with fellow workers and social support from supervisors tended to reduce the risk of disability retirement. The relationships persisted after control for socioeconomic factors, prevalent disease, and health behavior, which were also associated with disability retirement. The strong associations found between workplace factors and the incidence of disability retirement link the problem of disability retirement to the problem of poor work conditions.

    The article describes attitudes to disability and physically disabled people, taking into account the aspect of ethical and social location, what physically disabled meant in societies, and ways to solve the problems of disability. The article is based on studies of disability and historical sources. Christ's attitude shown in the Gospels changed the traditional cultures of the ancient treatment of disability in terms of it being seen as a penalty of the divine. The development of Christianity caused a gradual expansion of the ideas of charity, at the same time stepping up care and material support to all those physically disabled in need. Care of the disabled is based mostly on charity. Church activities supported, by the structure of the State and private individuals, was of paramount importance. Medieval society felt responsible for disabled people.

    Since the field-line mixing model of Giacalone et al. suggests that ion dropouts cannot happen in the “gradual” solar energetic particle (SEP) event because of the large size of the particle source region in the event, the observational evidence of ion dropouts in the gradual SEP event should challenge the model. We have searched for the presence of ion dropouts in the gradual SEP event during solar cycle 23. From 10 SEP events the synchronized occurrence of ion and electron dropouts is identified in 12 periods. Our main observational facts, including the mean width of electron–ion dropout periods being consistent with the solar wind correlation scale, during the dropout period the dominance of the slab turbulence component and the enhanced turbulence power parallel to the mean magnetic field, and the ion gyroradius dependence of the edge steepness in dropout periods, are all in support of the solar wind turbulence origin of dropout events. Also, our observation indicates that a wide longitude distribution of SEP events could be due to the increase of slab turbulence fraction with the increased longitude distance from the flare-associated active region.

    Full Text Available Anesthetizing an intellectually disabled patient is a challenge due to lack of cognition and communication which makes perioperative evaluation difficult. The presence of associated medical problems and lack of cooperation further complicates the anesthetic technique. An online literature search was performed using keywords anesthesia, intellectually disabled, and mentally retarded and relevant articles were included for review. There is scarcity of literature dealing with intellectually disabled patients. The present review highlights the anesthetic challenges, their relevant evidence-based management, and the role of caretakers in the perioperative period. Proper understanding of the associated problems along with a considerate and unhurried approach are the essentials of anesthetic management of these patients.

  11. Infertility: Inability or Disability?

    Full Text Available Disability is a complex phenomenon. It reflects an interaction between features of a person’s body and features of the society in which he or she lives. International Classification of Functioning, Disability and Health (ICF, lays stress on the functional as well as the structural problem of a person. All the definitions of disability also include the disorders of the reproductive and endocrine system. So infertility and impotency should also be included in the category of disability. It affects the participation in areas of life and can have a disabling affect on an individual. Like any other disability the couple has to adapt and integrate infertility in their sense of self thus infertility comes as a major life crisis. Medically, infertility, in most cases, is considered to be the result of a physical impairment or a genetic abnormality. Socially, couples are incapable of their reproductive or parental roles. On social level, infertility in most cultures remains associated with social stigma and taboo just like the social model of disability. Couples who are unable to reproduce may be looked down upon due to social stigmatisation. Infertility can lead to divorces and separation leading to a broken family life. Without labelling infertility as a disability, it is difficult for the people to access services and welfare benefits offered by the government. Infertility treatments are highly sophisticated so they are very expensive and are even not covered by insurance and government aid.In the light of all this it becomes imperative to categorise infertility as disability.

    The choroid is an important structure of the eye and plays a vital role in the pathology of retinal diseases. This paper presents an automated choroid segmentation method for high-definition optical coherence tomography (HD-OCT) images, including Bruch's membrane (BM) segmentation and choroidal-scleral interface (CSI) segmentation. An improved retinal nerve fiber layer (RNFL) complex removal algorithm is presented to segment BM by considering the structure characteristics of retinal layers. By analyzing the characteristics of CSI boundaries, we present a novel algorithm to generate a gradual intensity distance image. Then an improved 2-D graph search method with curve smooth constraints is used to obtain the CSI segmentation. Experimental results with 212 HD-OCT images from 110 eyes in 66 patients demonstrate that the proposed method can achieve high segmentation accuracy. The mean choroid thickness difference and overlap ratio between our proposed method and outlines drawn by experts was 6.72µm and 85.04%, respectively.

    1996-09-01

    Digital video computing and organization is one of the important issues in multimedia system, signal compression, or database. Video should be segmented into shots to be used for identification and indexing. This approach requires a suitable method to automatically locate cut points in order to separate shot in a video. Automatic cut detection to isolate shots in a video has received considerable attention due to many practical applications; our video database, browsing, authoring system, retrieval and movie. Previous studies are based on a set of difference mechanisms and they measured the content changes between video frames. But they could not detect more special effects which include dissolve, wipe, fade-in, fade-out, and structured flashing. In this paper, a new cut detection method for gradual transition based on computer vision techniques is proposed. And then, experimental results applied to commercial video are presented and evaluated.

    Participation in recreational and competitive sports at an early age has long been touted as a positive influence on growth and development, and for fostering lifelong healthy lifestyles. The benefits of an active lifestyle include not only fitness, but the promotion of a sense of inclusion and improved self-esteem. These benefits are well documented in all populations, and their importance has been summarized in the recent Healthy People 2010 guidelines. The American Academy of Pediatrics has recently produced a summary statement on the benefits of activity for disabled children. They note that children with disabilities tend to have an overall lower level of fitness and an increased level of obesity. For this population, developing a lifelong desire to be active can be a simple means for limiting illness and much of the morbidity associated with sedentary lifestyles often associated with disability. For disabled youth, participation in disabled sports programs available nationally and internationally can be an effective means to promote such precepts. The goal of this focused review is to improve the learner's knowledge of the positive impact that active lifestyles can have on overall health in the disabled youth population and, as a result, modify their practice by incorporating recreational and competitive sport activities as part of improving overall patient care.

    As the solar photovoltaic (PV) power is applied extensively, more attentions are paid to the maintenance and fault diagnosis of PV power plants. Based on analysis of the structure of PV power station, the global partitioned gradually approximation method is proposed as a fault diagnosis algorithm to determine and locate the fault of PV panels. The PV array is divided into 16x16 blocks and numbered. On the basis of modularly processing of the PV array, the current values of each block are analyzed. The mean current value of each block is used for calculating the fault weigh factor. The fault threshold is defined to determine the fault, and the shade is considered to reduce the probability of misjudgments. A fault diagnosis system is designed and implemented with LabVIEW. And it has some functions including the data realtime display, online check, statistics, real-time prediction and fault diagnosis. Through the data from PV plants, the algorithm is verified. The results show that the fault diagnosis results are accurate, and the system works well. The validity and the possibility of the system are verified by the results as well. The developed system will be benefit for the maintenance and management of large scale PV array.

    Many youths with disabilities find it challenging to disclose their medical condition and request workplace accommodations. Our objective was to explore when and how young people with disabilities disclose their condition and request workplace accommodations. We conducted 17 in-depth interviews (11 females, six males) with youth with disabilities aged 15-34 (mean age 26). We analyzed our data using an interpretive, qualitative, and thematic approach. Our results showed the timing of when youth disclosed their disability to their employer depended on disability type and severity, comfort level, type of job, and industry. Youth's strategies and reasons for disclosure included advocating for their needs, being knowledgeable about workplace rights, and accommodation solutions. Facilitators for disclosure included job preparation, self-confidence, and self-advocacy skills, and having an inclusive work environment. Challenges to disability disclosure included the fear of stigma and discrimination, lack of employer's knowledge about disability and accommodations, negative past experiences of disclosing, and not disclosing on your own terms. Our findings highlight that youth encounter several challenges and barriers to disclosing their condition and requesting workplace accommodations. The timing and process for disclosing is complex and further work is needed to help support youth with disclosing their condition. Implications for rehabilitation Clinicians, educators, and employers should emphasize the importance of mentoring and leadership programs to give youth the confidence and self-advocacy skills needed to disclose and ask for accommodations in the workplace. Clinicians should advocate for the inclusion of youth with disabilities in the workforce and educate employers on the importance of doing so. Youth with disabilities need more opportunities for employment training and particularly how to disclose their disability and request workplace accommodations.

    To report the results of a cohort of patients treated with this technique high lighting radiological and functional outcomes, discussing also benefits arising from a gradual reduction procedure compared with other techniques. We evaluated nine patients who have undergone high-grade listhesis reduction and circumferential fusion at our institution from 1988 to 2006. Average length of follow-up was 11 years (5-19). Functional outcomes and radiological measurements were recorded and reported. Slip magnitude was reduced by an average of 2.9 grades (Meyerding classification). Slip angle improved by an average of 66% (p = 0.0001), lumbosacral angle by 47% (p = 0.0002), sacral rotation by 51% (p = 0.0068) and sacral inclination by 47% (p = 0.0055). At the latest follow-up 88.9% had achieved solid fusion. Post-operative 10-point Visual Analogue Score (VAS) for back pain had improved by 70% (p Average postoperative Oswestry Disability Index for all patients was 8% (range 0-16%) and that for Low Back Outcome Scores was 56.6 (range 44-70). All components of Short Form 36 Health Survey were greater than 80%. Overall patients' expectations were met in 100%. This is an effective and safe technique which addresses the lumbosacral kyphosis and cosmetic deformity without the neurological complications which accompany other reduction and fusion techniques for high-grade spondylolisthesis.

Gradual elongation of the PT was performed using external fixation for 4 weeks, with a lengthening speed of 0.5 mm/day (elongation group; n = 24. Rabbits in the sham group underwent the same surgical procedure without gradual elongation (sham group; n = 24. Eight animals were sacrificed 1, 2 and 4 weeks after surgery in each group, respectively. Average thicknesses of stained glycosaminoglycan (GAGs areas by Safranin-O staining in the total cartilage layer and the uncalcified fibrocartilage layer in the elongation group were significantly higher than that in the sham group at 4 weeks (p < 0.05 and that in the intact PT group (n = 6, p < 0.05. In the elongation group, the peak in the average thicknesses of the stained GAGs areas in the total cartilage layer and the uncalcified fibrocartilage layer were observed at 4 weeks. Gradual elongation of PT insertion significantly affected the increase in the average thicknesses of the stained GAGs areas in the cartilage layer especially in the uncalcified fibrocartilage layer at 4 weeks in rabbits. Clinically, insertions of tendon and ligament can extend during gradual elongation using external fixation more than 4 weeks after the operation.

    Full Text Available Salinity is one the major limiting environmental factors which has negative side effects on crop production. The purpose of this study was to investigate the differences between the gradual and sudden salt stress effects on biomass accumulation associated with whole plant development in three different tissues of two wheat species ( Triticum aestivum and Triticum durum under hydroponic conditions in the long term. Considering the effects of sudden and gradual stress for biomass accumulation, while importance of salinity x genotype interaction for fresh weights was 5%, association for salinity x tissue type was found as 1% important. Interestingly, root branching and development of lateral roots were much more negatively affected by gradual stress rather than sudden salt application. Our results demonstrated that root and leaf were both critical tissues to test the salt tolerance by physiologically but sheath tissue might be used as an alternative source of variation for solving the interactions between root and leaves in wheat.

    The aim of this study was to examine if gradual withdrawal of remifentanil infusion prevented opioid-induced hyperalgesia (OIH) as opposed to abrupt withdrawal. OIH duration was also evaluated. Nineteen volunteers were enrolled in this randomized, double-blinded, placebo-controlled, crossover study. All went through three sessions: abrupt or gradual withdrawal of remifentanil infusion and placebo. Remifentanil was administered at 2.5 ng ml(-1) for 30 min before abrupt withdrawal or gradual withdrawal by 0.6 ng ml(-1) every five min. Pain was assessed at baseline, during infusion, 45-50 min and 105-110 min after end of infusions using the heat pain test (HPT) and the cold pressor test (CPT). The HPT 45 min after infusion indicated OIH development in the abrupt withdrawal session with higher pain scores compared with the gradual withdrawal and placebo sessions (both Pwithdrawal compared with placebo (P=0.93). In the CPT 50 min after end of infusion there was OIH in both remifentanil sessions compared with placebo (gradual P=0.01, abrupt Pwithdrawal of remifentanil infusion in the HPT. After abrupt withdrawal OIH was present in the HPT. In the CPT there was OIH after both gradual and abrupt withdrawal of infusion. The duration of OIH was less than 105 min for both pain modalities.

    We consider a repairable system with continuous output that alternates between states of operation and repair. The output of the system in the operating state is represented by a continuous, decreasing function of time. We assume that during the repair state, the system can produce output that is modelled by an increasing stochastic process. The repair action gradually restores the output of the system to its initial level and it returns to the operating state. We obtain and analyse expressions for the generalized availability and related characteristics of systems with gradual repair and consider several meaningful examples

    Full Text Available Abstract My research will focus on some of the more pertinent changes that need to take place on a societal level in order to better serve disabled people and allow them to participate in all facets of community life. I will argue that three of the most significant changes that must take place include educating society on disabilities and disabled persons creating and enforcing better laws that truly help disabled persons and expanding the definitions of disability and disabled person to include a broader spectrum of ailments inflictions and handicaps. The changes which I support will be presented in a research-driven paper. I will highlight the current UK disability laws in place and point out some of their shortcomings. Then I will explore the worldview of society as a whole as it pertains to disabled peoples and suggest changes that need to take place and how educators can help facilitate these changes. Finally I will explain the shortcomings of the most common definitions used for disability and disabled persons and offer alternatives that incorporate a broader range of people and ailments. My audience will be any citizen whose political jurisdiction is under the UK disability mandate although anyone from any society would benefit from reading my paper due to the universality of this topic.

    The appropriate timing of flowering is crucial for the reproductive success of plants. Hence, intricate genetic networks integrate various environmental and endogenous cues such as temperature or hormonal statues. These signals integrate into a network of floral pathway integrator genes. At a quantitative level, it is currently unclear how the impact of genetic variation in signaling pathways on flowering time is mediated by floral pathway integrator genes. Here, using datasets available from literature, we connect Arabidopsis thaliana flowering time in genetic backgrounds varying in upstream signalling components with the expression levels of floral pathway integrator genes in these genetic backgrounds. Our modelling results indicate that flowering time depends in a quite linear way on expression levels of floral pathway integrator genes. This gradual, proportional response of flowering time to upstream changes enables a gradual adaptation to changing environmental factors such as temperature and light.

    2011-03-09

    Two patients, one with colour agnosia and one with brightness agnosia, performed a task that required the detection of gradual temporal changes in colour and brightness. The results for these patients, who showed anaverage or an above-average performance on several tasks designed to test low-level colour and luminance (contrast) perception in the spatial domain, yielded a double dissociation; the brightness agnosic patient was within the normal range for the coloured stimuli, but much slower to detect brightness differences, whereas the colour agnosic patient was within the normal range for the achromatic stimuli, but much slower for the coloured stimuli. These results suggest that a modality-specific impairment in the detection of gradual temporal changes might be related to, if not underlie, the phenomenon of visual agnosia.

  14. Computational issues of solving the 1D steady gradually varied flow equation

    Directory of Open Access Journals (Sweden)

    Artichowicz Wojciech

    2014-09-01

    Full Text Available In this paper a problem of multiple solutions of steady gradually varied flow equation in the form of the ordinary differential energy equation is discussed from the viewpoint of its numerical solution. Using the Lipschitz theorem dealing with the uniqueness of solution of an initial value problem for the ordinary differential equation it was shown that the steady gradually varied flow equation can have more than one solution. This fact implies that the nonlinear algebraic equation approximating the ordinary differential energy equation, which additionally coincides with the wellknown standard step method usually applied for computing of the flow profile, can have variable number of roots. Consequently, more than one alternative solution corresponding to the same initial condition can be provided. Using this property it is possible to compute the water flow profile passing through the critical stage.

  18. Impairment of gradual muscle adjustment during wrist circumduction in Parkinson's disease.

    Directory of Open Access Journals (Sweden)

    Carolien M Toxopeus

    Full Text Available Purposeful movements are attained by gradually adjusted activity of opposite muscles, or synergists. This requires a motor system that adequately modulates initiation and inhibition of movement and selectively activates the appropriate muscles. In patients with Parkinson's disease (PD initiation and inhibition of movements are impaired which may manifest itself in e.g. difficulty to start and stop walking. At single-joint level, impaired movement initiation is further accompanied by insufficient inhibition of antagonist muscle activity. As the motor symptoms in PD primarily result from cerebral dysfunction, quantitative investigation of gradually adjusted muscle activity during execution of purposeful movement is a first step to gain more insight in the link between impaired modulation of initiation and inhibition at the levels of (i cerebrally coded task performance and (ii final execution by the musculoskeletal system. To that end, the present study investigated changes in gradual adjustment of muscle synergists using a manipulandum that enabled standardized smooth movement by continuous wrist circumduction. Differences between PD patients (N = 15, off-medication and healthy subjects (N = 16 concerning the relation between muscle activity and movement performance in these groups were assessed using kinematic and electromyographic (EMG recordings. The variability in the extent to which a particular muscle was active during wrist circumduction--defined as muscle activity differentiation--was quantified by EMG. We demonstrated that more differentiated muscle activity indeed correlated positively with improved movement performance, i.e. higher movement speed and increased smoothness of movement. Additionally, patients employed a less differentiated muscle activity pattern than healthy subjects. These specific changes during wrist circumduction imply that patients have a decreased ability to gradually adjust muscles causing a decline in

    The causal correlations between human genetic variants and linguistic (typological) features could represent the mechanism required for gradual, accretionary models of language evolution. The causal link is mediated by the process of cultural transmission of language across generations in a population of genetically biased individuals. The particular case of Tone, ASPM and Microcephalin is discussed as an illustration. It is proposed that this type of genetically-influenced linguistic bias, c...

    A recent political decree in Denmark outlined an ambitious goal regarding the inclusion of students with special needs in the general education. 97% of the country’s students are to receive their education in the public school’s general education by 2020. Research indicates that the use of in......-class support is a central pedagogical approach towards a more inclusive school, and that in-class supportive practices can entail positive implications for students with special educational needs. However, research also indicates that the application of in-class support may lead to more negative consequences...... for these students (Alborz, 2009; Blatchford et al., 2009; Blatchford, Bassett, Brown, & Webster, 2009; Dyssegaard & Larsen, 2013).

  4. Gradual plasticity alters population dynamics in variable environments: thermal acclimation in the green alga Chlamydomonas reinhartdii.

    Environmental variability is ubiquitous, but its effects on populations are not fully understood or predictable. Recent attention has focused on how rapid evolution can impact ecological dynamics via adaptive trait change. However, the impact of trait change arising from plastic responses has received less attention, and is often assumed to optimize performance and unfold on a separate, faster timescale than ecological dynamics. Challenging these assumptions, we propose that gradual plasticity is important for ecological dynamics, and present a study of the plastic responses of the freshwater green algae Chlamydomonas reinhardtii as it acclimates to temperature changes. First, we show that C. reinhardtii 's gradual acclimation responses can both enhance and suppress its performance after a perturbation, depending on its prior thermal history. Second, we demonstrate that where conventional approaches fail to predict the population dynamics of C. reinhardtii exposed to temperature fluctuations, a new model of gradual acclimation succeeds. Finally, using high-resolution data, we show that phytoplankton in lake ecosystems can experience thermal variation sufficient to make acclimation relevant. These results challenge prevailing assumptions about plasticity's interactions with ecological dynamics. Amidst the current emphasis on rapid evolution, it is critical that we also develop predictive methods accounting for plasticity. © 2018 The Author(s).

  5. Chronic environmental stress enhances tolerance to seasonal gradual warming in marine mussels.

    Directory of Open Access Journals (Sweden)

    Ionan Marigómez

    Full Text Available In global climate change scenarios, seawater warming acts in concert with multiple stress sources, which may enhance the susceptibility of marine biota to thermal stress. Here, the responsiveness to seasonal gradual warming was investigated in temperate mussels from a chronically stressed population in comparison with a healthy one. Stressed and healthy mussels were subjected to gradual temperature elevation for 8 days (1°C per day; fall: 16-24°C, winter: 12-20°C, summer: 20-28°C and kept at elevated temperature for 3 weeks. Healthy mussels experienced thermal stress and entered the time-limited survival period in the fall, became acclimated in winter and exhibited sublethal damage in summer. In stressed mussels, thermal stress and subsequent health deterioration were elicited in the fall but no transition into the critical period of time-limited survival was observed. Stressed mussels did not become acclimated to 20°C in winter, when they experienced low-to-moderate thermal stress, and did not experience sublethal damage at 28°C in summer, showing instead signs of metabolic rate depression. Overall, although the thermal threshold was lowered in chronically stressed mussels, they exhibited enhanced tolerance to seasonal gradual warming, especially in summer. These results challenge current assumptions on the susceptibility of marine biota to the interactive effects of seawater warming and pollution.

  6. Molecular sieving action of the cell membrane during gradual osmotic hemolysis

    Energy Technology Data Exchange (ETDEWEB)

    MacGregor, R.D. II

    1977-05-01

    Rat erythrocytes were hemolyzed by controlled gradual osmotic hemolysis to study cell morphology and hemoglobin loss from individual cells. Results suggest that each increase in the rate of loss of a protein from the cells during the initial phases of controlled gradual osmotic hemolysis is caused by the passage of a previously impermeable species across the stressed membrane. Similarly, during the final stages of controlled gradual osmotic hemolysis, each sharp decrease in the rate of loss of a protein corresponds to the termination of a molecular flow. A theoretical model is described that predicts the molecular sieving of soluble globular proteins across the stressed red cell membrane. Hydrophobic interactions occur between the soluble proteins and the lipid bilayer portion of the cell membrane. A spectrin network subdivides the bilayer into domains that restrict the insertion of large molecules into the membrane. Other membrane proteins affect soluble protein access to the membrane. Changes in the loss curves caused by incubation of red cells are discussed in terms of the model.

    There is increasing evidence that sensorimotor learning under real-life conditions relies on a composition of several learning processes. Nevertheless, most studies examine learning behaviour in relation to one specific learning mechanism. In this study, we examined the interaction between reward-based skill acquisition and motor adaptation to changes of object dynamics. Thirty healthy subjects, split into two groups, acquired the skill of balancing a pole on a cart in virtual reality. In one group, we gradually increased the gravity, making the task easier in the beginning and more difficult towards the end. In the second group, subjects had to acquire the skill on the maximum, most difficult gravity level. We hypothesized that the gradual increase in gravity during skill acquisition supports learning despite the necessary adjustments to changes in cart-pole dynamics. We found that the gradual group benefits from the slow increment, although overall improvement was interrupted by the changes in gravity and resulting system dynamics, which caused short-term degradations in performance and timing of actions. In conclusion, our results deliver evidence for an interaction of reward-based skill acquisition and motor adaptation processes, which indicates the importance of both processes for the development of optimized skill acquisition schedules.

  8. Shakespeare on old age and disability.

    Science.gov (United States)

    Covey, H

    2000-01-01

    The plays of William Shakespeare were reviewed for references to disabilities, aging and disability, and older characters with disabilities. Shakespeare's references draw from traditional cultural notions about older people with disabilities. These traditional notions include people with physical disabilities being evil, the entertainment value of disabilty, and those who were mentally ill being wild and animal-like. He viewed the aging process as disabling and old age as a time when individuals lost some abilities to function, particularly when it came to mental capacity and physical mobility. His writings show that he used disability as a literary tool to add dimension to characters and set them apart. Contemporary literature continues to share some of Shakespeare's view on aging and disability but also departs from them in important ways. For example, contemporary treatment of disabilities and aging places more emphasis on the human side of the affects of aging and disabilities. Disabilities and aging are not cast in the same negative terms as Shakespeare used.

    Weaning from extracorporeal life support (ELS) is particularly challenging when cardiac recovery is slow, largely incomplete and hard to predict. Therefore, we describe an individualized gradual weaning strategy using an arterio-venous (AV) bridge incorporated into the circuit to facilitate weaning. Thirty adult patients weaned from veno-arterial ELS using an AV bridge were retrospectively analyzed. Serial echocardiography and hemodynamic monitoring were used to assess cardiac recovery and load responsiveness. Upon early signs of myocardial recovery, an AV bridge with an Hoffman clamp was added to the circuit and weaning was initiated. Support flow was reduced stepwise by 10-15% every 2 to 8 hours while the circuit flow was maintained at 3.5-4.5 L/min. The AV bridge facilitated gradual weaning in all 30 patients (median age: 66 [53-71] years; 21 males) over a median period of 25 [8-32] hours, with a median support duration of 96 [31-181] hours. During weaning, the median left ventricular ejection fraction was 25% [15-32] and the median velocity time integral of the aortic valve was 16 cm [10-23]. Through the weaning period, the mean arterial blood pressure was maintained at 70 mmHg and the activated partial thromboplastin time was 60 ± 10 seconds without additional systemic heparinization. Neither macroscopic thrombus formation in the ELS circuit during and after weaning nor clinically relevant thromboembolism was observed. Incorporation of an AV bridge for weaning from veno-arterial ELS is safe and feasible to gradually wean patients with functional cardiac recovery without compromising the circuit integrity. © The Author(s) 2015.

    It is generally believed that coronal mass ejections CMEs are the drivers of shocks that accelerate gradual solar energetic particles SEPs One might expect that the characteristics of the SEP intensity time profiles observed at 1 AU are determined by properties of the associated CMEs such as the radial speed and the angular width Recently Kahler statistically investigated the characteristic times of gradual SEP events observed from 1998-2002 and their associated coronal mass ejection properties Astrophys J 628 1014--1022 2005 Three characteristic times of gradual SEP events are determined as functions of solar source longitude 1 T 0 the time from associated CME launch to SEP onset at 1 AU 2 T R the rise time from SEP onset to the time when the SEP intensity is a factor of 2 below peak intensity and 3 T D the duration over which the SEP intensity is within a factor of 2 of the peak intensity However in his study the CME speeds and angular widths are directly taken from the LASCO CME catalog In this study we analyze the radial speeds and the angular widths of CMEs by an ice-cream cone model and re-investigate their correlationships with the characteristic times of the corresponding SEP events We find T R and T D are significantly correlated with radial speed for SEP events in the best-connected longitude range and there is no correlation between T 0 and CME radial speed and angular width which is consistent with Kahler s results On the other hand it s found that T R and T D are also have

    An electrolyte supported solid oxide fuel cell (SOFC) using standard electrodes, doped-lanthanum manganite cathode and Ni-cermet anode, was operated with direct (anhydrous) ethanol for more than 100 h, delivering essentially the same power output as running on hydrogen. A ceria-based layer provides the catalytic activity for the gradual internal reforming, which uses the steam formed by the electrochemical oxidation of hydrogen for the decomposition of ethanol. Such a concept opens up the way for multi-fuel SOFCs using standard components and a catalytic layer.

  12. Social representations of climate change in Swedish lay focus groups: local or distant, gradual or catastrophic?

    2014-02-01

    This paper explores social representations of climate change, investigating how climate change is discussed by Swedish laypeople interacting in focus group interviews. The analysis focuses on prototypical examples and metaphors, which were key devices for objectifying climate change representations. The paper analyzes how the interaction of focus group participants with other speakers, ideas, arguments, and broader social representations shaped their representations of climate change. Climate change was understood as a global but distant issue with severe consequences. There was a dynamic tension between representations of climate change as a gradual vs. unpredictable process. Implications for climate change communication are discussed.

It systematically examines costs faced by an internationalizing firm and how firms react to these costs according to “distance-dependent” (gradual and regional) and “distance-invariant” (born-global) explanations...... of internationalization. Data on 5827 country pages of 240 multinational firms on Facebook, the most popular SNS today, is used. Creating a foreign country-specific Facebook page is considered the SNS equivalent of opening a physical subsidiary in that country. The data show that multinationals exhibit...

    Vario-scale data structures have been designed to support gradual content zoom and the progressive transfer of vector data, for use with arbitrary map scales. The focus to date has been on the server side, especially on how to convert geographic data into the proposed vario-scale structures by means of automated generalisation. This paper contributes to the ongoing vario-scale research by focusing on the client side and communication, particularly on how this works in a web-services setting. It is claimed that these functionalities are urgently needed, as many web-based applications, both desktop and mobile, require gradual content zoom, progressive transfer and a high performance level. The web-client prototypes developed in this paper make it possible to assess the behaviour of vario-scale data and to determine how users will actually see the interactions. Several different options of web-services communication architectures are possible in a vario-scale setting. These options are analysed and tested with various web-client prototypes, with respect to functionality, ease of implementation and performance (amount of transmitted data and response times). We show that the vario-scale data structure can fit in with current web-based architectures and efforts to standardise map distribution on the internet. However, to maximise the benefits of vario-scale data, a client needs to be aware of this structure. When a client needs a map to be refined (by means of a gradual content zoom operation), only the 'missing' data will be requested. This data will be sent incrementally to the client from a server. In this way, the amount of data transferred at one time is reduced, shortening the transmission time. In addition to these conceptual architecture aspects, there are many implementation and tooling design decisions at play. These will also be elaborated on in this paper. Based on the experiments conducted, we conclude that the vario-scale approach indeed supports gradual

    Full Text Available This paper aims to question the living conditions of disabled people in the 21st century from  the framework of social justice. The concept of “social justice” has a long history, influenced  by the works of numerous writers including Rawls (1971, Miller (1999, Reeves (2005, Fainstein (2009, Marcuse (2009 and Harvey (1992, 2009 and by the recent debates on  inequality, diversity, segregation, exclusion, and discrimination. The debates on segregation, exclusion and discrimination are generally focused on inequalities in terms of economic,  ethnic and gender dimensions; however, in these debates, there is very little reference to unequal opportunities of disabled people. On the other hand, the diversity issue is generally discussed with respect to ethnic and cultural elements, again with very little concern for the  rights of disabled people. In many developing countries, including Turkey, a legal framework  for addressing disability issues has started to be put in place. Awareness among governments and society of the needs and rights of people with disabilities is growing. In the  last decade in Turkey, the difficulties faced by disabled people have started to be taken into  consideration seriously. Before that, the only information about the disabled population could  be obtained from General Population Census in Turkey. In 2002 “Turkey Disability Survey” was carried out collectively by the State Institute of Statistics and the Presidency of  Administration on Disabled People. In this survey, it has been targeted to estimate the number of disabled people and comprehend their socio-economic characteristics, their  problems in social life, expectations, types and causes of disability, regional differences and also the proportion of population having chronic illnesses. After this survey, many projects  have started to be realized in order to propose strategies for eliminating discrimination in  Turkey. In this paper, we will

    Disability is not a category of disease but rather relates to the physical, sensory, cognitive, and/or mental disorders that substantially limit one or more major life activities. These functional limitations have been found to be predictive of suicide, with psychiatric comorbidities increasing the risk for suicide. Enormous gaps exist in the understanding of the relationship between disability and suicide. We reviewed the current literature addressing the prevalence of and risk factors for suicide among persons with three major disabling conditions and identify priorities for future research. We performed a literature review investigating the relationship between three major disabilities (intellectual disability, spinal cord injury, multiple sclerosis) and suicide. To ensure thorough evaluation of the available literature, we searched PubMed, the Cochrane Library, and Google Scholar with terms including "suicide," "disability," "intellectual disability," "spinal cord injury," "multiple sclerosis," and permutations thereof. By this method we evaluated 110 articles and included 21 in the review. Suicide rates are significantly higher among persons with multiple sclerosis and spinal cord injury than in the general population. A more nuanced picture of suicide rates and risk factors exists for the intellectual disability population, in which it appears that rates of suicide risk factors are higher than among the general population while suicide rates may be lower. The highest rates of suicide are reported among study populations of persons with multiple sclerosis, followed by persons with spinal cord injury, and then individuals with intellectual disability. Suicide among persons with disabilities is a complex and pressing public health concern. Urgent research priorities include (1) valid estimates of suicide rates among persons with disabilities by age cohort; (2) assessment of the predictive importance of suicide risk factors; and (3) determination of best

  18. Study on FPGA-Based Emulator for the Diagnosis of Gradual Degradation in Reciprocating Pump

    The purpose of this study is to develop a method for diagnosing the degree of gradual degradation of a reciprocating pump caused by continuous use as a water supply pump in a nuclear power plant. Normally, the progress of such degradation is too slow to be noticed. Hence, it is difficult to determine the degree of degradation using the existing diagnostic methods. In this paper, we propose a new method by which the normal state and the degraded state of the pump can be differentiated, so that the degree of degradation can be identified. First, an emulator was developed using FPGA by providing the parameters of the pump under normal state, so that the emulator generates the information of the pump in the healthy state. Then, by comparing this information with the parameters received from various output sensors of the emulator during the current state, it is possible to identify and measure the degree of gradual degradation. This paper presents some of the results obtained during the development process, and results that show how the emulator operates, by comparing the data collected from an actual pump.

  19. Optimal cellular mobility for synchronization arising from the gradual recovery of intercellular interactions

    International Nuclear Information System (INIS)

    2012-01-01

    Cell movement and intercellular signaling occur simultaneously during the development of tissues, but little is known about how movement affects signaling. Previous theoretical studies have shown that faster moving cells favor synchronization across a population of locally coupled genetic oscillators. An important assumption in these studies is that cells can immediately interact with their new neighbors after arriving at a new location. However, intercellular interactions in cellular systems may need some time to become fully established. How movement affects synchronization in this situation has not been examined. Here, we develop a coupled phase oscillator model in which we consider cell movement and the gradual recovery of intercellular coupling experienced by a cell after movement, characterized by a moving rate and a coupling recovery rate, respectively. We find (1) an optimal moving rate for synchronization and (2) a critical moving rate above which achieving synchronization is not possible. These results indicate that the extent to which movement enhances synchrony is limited by a gradual recovery of coupling. These findings suggest that the ratio of time scales of movement and signaling recovery is critical for information transfer between moving cells. (paper)

  20. Influence of gradual density transition and nonlinear saturation on Rayleigh-Taylor instability growth

    International Nuclear Information System (INIS)

    Jacobs, H.

    1984-08-01

    Linear theory of Rayleigh-Taylor instability growth at a density profile which varies exponentially between regions of constant density is discussed in detail. The exact theory provides an approximate but conservative simple formula for the growth constant and it shows that a hitherto widely used theory erroneously underestimates the growth constant. A simple but effective ''synthetical model'' of nonlinear bubble growth is obtained from a synthesis of linear theory and constant terminal bubble speed. It is applied to pusher shell break-up in an inertial confinement fusion pellet to determine the maximum allowable initial perturbations and the most dangerous wavelength. In a situation typical of heavy ion drivers it is found that the allowable initial perturbations are increased by a few orders of magnitude by the gradual density transition and another order of magnitude by nonlinear saturation of the bubble speed. The gradual density transition also shifts the most dangerous wavelength from about once to about four times the minimum pusher shell thickness. The following topics are treated briefly: Reasons conflicting with use of the synthetical model to decide whether the pusher shell in a certain simulation will be broken up; other nonlinear theories available in the literature; further realistic effects that might aggravate instability growth.

    The purpose of this study is to clarify the reactions of the neuro-muscular junction and nerve cell body to gradual nerve elongation. The sciatic nerves of Japanese white rabbits were lengthened by 30 mm in increments of 0.8 mm/day, 2.0 mm/day and 4.0 mm/day. A scanning electron microscopic examination showed no degenerative change at the neuro-muscular junction, even eight weeks after elongation in the 4-mm group. Hence, neuro-muscular junction is not critical for predicting damage from gradual nerve elongation. There were no axon reaction cells in the 0.8-mm group, a small amount in the 2-mm group, and a large amount in the 4-mm group. The rate of growth associated protein-43 positive nerve cells was significant in the 4-mm group. Hence, the safe speed for nerve cells appeared to be 0.8-mm/day, critical speed to be 2.0-mm/day, and dangerous speed to be 4.0-mm/day in this elongation model.

    This article reports on an empirical study that aimed to design a practice-based theory about collaboration on the local implementation of a nationally developed health-promoting intervention. The study's objective is to better understand the dynamic process of complex collaboration. The research is based on a Delphi study among some 100 individuals in local and regional networks, in which various professionals work together to implement the BeweegKuur, which translates as 'course of exercise'. The BeweegKuur is a combined lifestyle intervention aimed at promoting sufficient physical exercise and a healthy diet among people in the Netherlands who are overweight and at risk of diabetes. The Delphi study in three rounds systematically and interactively constructs a common perspective on implementation, reflecting stakeholders' ideas about the collaboration and providing an insight into how these ideas are influenced by the context of the implementation. The statistical and qualitative analyses of the responses to the feedback in the Delphi study form the basis for this practice-based theory on complex collaboration, called the theory of gradual commonality. During interaction, consensus gradually emerges about co-creation as a collaboration strategy. Co-creation leaves room for various ways of achieving the ambitions of the BeweegKuur. This article discusses the importance of this practice-based theory and the value of the Delphi research strategy for promoting health. © The Author 2014. Published by Oxford University Press.

  3. Experimental test of Neel's theory of the Rayleigh rule using gradually devitrified Co-based glass

    2000-01-01

    It is shown that gradually devitrified Co-based nonmagnetostrictive metallic glass is an excellent model material to verify Louis Neel's theory of the Rayleigh rule. In the course of the calculations, Neel showed that the parameter p=bH c /a (where H c is the coercivity, a and b are the coefficients of a quadratic polynomial expressing the Rayleigh rule) is expected to range between 0.6 (hard magnets) and 1.6 (soft). However, the experimental values of this parameter, reported in the literature for a number of mono- and poly-crystalline magnets, are much greater than those expected from the theory presented by Neel (in some cases even by two orders of magnitude). The measurements, performed for a series of Co-based metallic glass samples annealed at gradually increasing temperature to produce nanocrystalline structures with differentiated density and size of the crystallites, have shown that the calculated values of the parameter p fall within the range expected from Neel's theory

    The optimal oxygen administration strategy during resuscitation from hemorrhagic shock (HS) is still controversial. Improving oxygenation and mitigating oxidative stress simultaneously seem to be contradictory goals. To maximize oxygen delivery while minimizing oxidative damage, the authors proposed the notion of gradually increased oxygen administration (GIOA), which entails making the arterial blood hypoxemic early in resuscitation and subsequently gradually increasing to hyperoxic, and compared its effects with normoxic resuscitation, hyperoxic resuscitation, and hypoxemic resuscitation in severe HS. Rats were subjected to HS, and on resuscitation, the rats were randomly assigned to four groups (n = 8): the normoxic, the hyperoxic, the hypoxemic, and the GIOA groups. Rats were observed for an additional 1 h. Hemodynamics, acid-base status, oxygenation, and oxidative injury were observed and evaluated. Central venous oxygen saturation promptly recovered only in the hyperoxic and the GIOA groups, and the liver tissue partial pressure of oxygen was highest in the GIOA group after resuscitation. Oxidative stress in GIOA group was significantly reduced compared with the hyperoxic group as indicated by the reduced malondialdehyde content, increased catalase activity, and the lower histologic injury scores in the liver. In addition, the tumor necrosis factor-α and interleukin-6 expressions in the liver were markedly decreased in the GIOA group than in the hyperoxic and normoxic groups as shown by the immunohistochemical staining. GIOA improved systemic/tissue oxygenation and mitigated oxidative stress simultaneously after resuscitation from severe HS. GIOA may be a promising strategy to improve resuscitation from HS and deserves further investigation.

  5. Enhanced Attention to Speaking Faces Versus Other Event Types Emerges Gradually Across Infancy

    The development of attention to dynamic faces vs. objects providing synchronous audiovisual vs. silent visual stimulation was assessed in a large sample of infants. Maintaining attention to the faces and voices of people speaking is critical for perceptual, cognitive, social, and language development. However, no studies have systematically assessed when, if, or how attention to speaking faces emerges and changes across infancy. Two measures of attention maintenance, habituation time (HT) and look-away rate (LAR), were derived from cross-sectional data of 2- to 8-month-old infants (N = 801). Results indicated that attention to audiovisual faces and voices was maintained across age, whereas attention to each of the other event types (audiovisual objects, silent dynamic faces, silent dynamic objects) declined across age. This reveals a gradually emerging advantage in attention maintenance (longer habituation times, lower look-away rates) for audiovisual speaking faces compared with the other three event types. At 2 months, infants showed no attentional advantage for faces (with greater attention to audiovisual than to visual events), at 3 months, they attended more to dynamic faces than objects (in the presence or absence of voices), and by 4 to 5 and 6 to 8 months significantly greater attention emerged to temporally coordinated faces and voices of people speaking compared with all other event types. Our results indicate that selective attention to coordinated faces and voices over other event types emerges gradually across infancy, likely as a function of experience with multimodal, redundant stimulation from person and object events.

    Hurley, Anne D

    2006-09-01

    This article examines reviews and research on the diagnosis and treatment of mood disorders in people with intellectual disability published from September 2004 to December 2005. Patients with intellectual disability have limitations in verbal ability, and with increasing levels of disability may have an atypical clinical presentation. Thus, methods to diagnose mood disorders were a major research focus. Informant-rating scales and two self-report instruments provided data on thought patterns, aberrant behavior, appetite, and suicidality. Behavioral symptoms such as aggression were frequently associated with mood disorders. Pharmacotherapy and electroconvulsive therapy were found to be effective treatments. Mood disorders were frequently identified in people with intellectual disability, although suicide was still quite rare. Patients with milder levels of disability can use self-report measures and can be diagnosed using standard criteria with little modification. For those with more severe disability, diagnosis is challenging and often requires the use of residual categories. Atypical clinical presentation, including maladaptive behaviors, lent support for 'behavioral equivalent' substitutes of standard criteria. Typical pharmacological agents were effective for depression and electroconvulsive therapy for treatment-resistant bipolar disorder.

    Ways of thinking about and responding to disability have radically changed in recent decades. Traditionally, disability was regarded in terms of sin, karma, or divine punishment. More recently, disability was made a medical issue and defined in terms of shortcomings of body or mind, which had to be prevented or cured at all costs. In the late 20th century, people with disabilities worldwide became more organised and created national and international disabled people’s organisations. They succ...

    The objective was to compare and correlate disability, pain intensity, the impact of headache on daily life and the fear of movement between subgroups of patients with chronic temporomandibular disorder (TMD). A cross-sectional study was conducted in patients diagnosed with chronic painful TMD. Patients were divided into: 1) joint pain (JP); 2) muscle pain (MP); and 3) mixed pain. The following measures were included: Craniomandibular pain and disability (Craniofacial pain and disability inventory), neck disability (Neck Dsiability Index), pain intensity (Visual Analogue Scale), impact of headache (Headache Impact Test 6) and kinesiophobia (Tampa Scale of Kinesiophobia-11). A total of 154 patients were recruited. The mixed pain group showed significant differences compared with the JP group or MP group in neck disability (p craniomandibular pain and disability (p Neck disability was a significant covariate (37 % of variance) of craniomandibular pain and disability for the MP group (β = 0.62; p neck disability (β = 0.40; p craniomandibular pain and disability.

    To examine the integration of disability-content in a national sample of nurse practitioner curricula. Responses of National Organization of Nurse Practitioner Faculties (NONPF) members to an online 34-item survey designed to assess disability-related content included in nurse practitioner (NP) curricula; populations of people with disabilities addressed; models of disability; and resources used to teach about disability, facilitators and barriers to inclusion of disability, and respondents' assessment of the adequacy of coverage of disability in their programs. A survey used previously to assess integration of disability content in undergraduate nursing programs was modified to make it relevant to NP curricula. Nursing faculty and people with disability validated the survey to ensure its completeness and sensitivity to the disability community. Participating programs represent 111 (33.6%) NP programs. Lack of disability-related content reported by NP faculty in the majority of programs suggests that there is considerable room for improvement in efforts to address this often vulnerable population. Because people with disabilities can be found in any setting where health care is provided, all NPs need to be prepared to care for people with disabilities across the life span. Strategies need to be developed and implemented to increase the awareness of NP faculty about the health issues of people with disabilities and integration of disability-related content without disrupting existing overloaded NP curricula. © 2014 American Association of Nurse Practitioners.

    Does situational leadership style impact workers with disabilities? Situational leadership as a model and style of organizational management is defined. With a concentration on workers with disabilities, employer and employee perceptions of the workplace environment are analyzed as a contributing factor to the choice of leadership styles. Leadership style and its potential impact on workers with disabilities are included. Advantages of situational leadership style as an organizational model for managers that matches the intricate needs of workers with disabilities are argued. Methods for increasing awareness of the needs of persons with disabilities in the workplace and improving leadership models are discussed. Implications and potential outcomes for workers with disabilities based on the use of situational leadership by managers are discussed.

    Full Text Available People with developmental disabilities can experience any psychological abnormalitiy and psychiatric illness as do people without developmental disabilities. Due to different diagnostic criteria, assessment procedures and instruments, we lack definite prevalence rates for people with developmental disabilities, also suffering from mental health problems, eventhough most studies place the rate at 20 to 40%. One of the possible treatment alternatives for augmenting psychological well-being is psychotherapy, but is extremely rarely used for people with severe and profound disabilities, where speech cannot be the main therapeutic medium. So, those that are included in the psychotherapuetic process are predominantly clients with mild developmental disabilities, and they are mostly in cognitive-behavioral therapy. Recently, two models of (psychotherapy for persons with severe and profound developmental disabilities were developed: developmental-dynamic relationship therapy and attachment-based behaviour therapy for children. Conceptually, they both originate form developmental psychoanalytic theories.

    Full Text Available Physical disability is termed as disturbance or defect which impede or eliminate human body’s ability by disturbing human structure and shape. Physical disability may occur due to neonatal, natal or postnatal causes. People with physical disability have some natural needs as everyone. They are known to have difficulties in many areas of life. In society, sexual lives of these individuals are treated as an unknown and ignored issue, and moreover it has been assumed that they have no such needs. Disabled patients experience many troubles in their life domains including sexuality. This article provides information about physical disability and sexuality, and difficulties with which disabled people faces in their sexual life and overviews literature on this topic.

    pH variation could cause a stress response in euryhaline penaeids, we evaluated the mortality, growth performance, osmoregulation gene expression, digestive enzyme activity, histology, and resistance against Vibrio parahemolyticus of white shrimp Litopenaeus vannamei reared under conditions of gradual changes to a low-pH environment (gradual-low pH, 6.65-8.20) or a high-pH environment (gradual-high pH, 8.20-9.81) versus a normal pH environment (8.14-8.31) during a 28-d experiment. Consequently, under gradual-high pH, the cumulative mortality rate (CMR) rose with time until 39.9% on days 28; the weight gain percentage (WGP) and length gain percentage (LGP) decreased continuously. However, under gradual-low pH, the CMR of shrimp stabilized at 6.67% during 7-28 d; the WGP and LGP decreased first and then returned to normal. These results indicated that L. vannamei displayed a moderate tolerance to gradual-low pH, compared with gradual-high pH. Under gradual-low pH, the Na + /K + -ATPase, cytoplasmic carbonic anydrase (CAc), and glycosyl-phosphatidylinositol-linked carbonic anhydrase (CAg) transcripts of shrimp increased continuously or then back to normal; the amylase, lipase, and trypsin activities decreased first and then returned to normal or increased; the hepatopancreases and midguts showed histopathological lesions first and then got remission. Thus, the major adaptation mechanism of shrimp to gradual-low pH might be its high osmoregulation ability, which made shrimp achieve a new, balanced steady-state, then promoted longer intestinal villi and recuperative hepatopancreases of shrimp with enhanced digestive enzyme activities to increase nutrient absorption after long-term exposure. Meanwhile, the enhanced resistance against V. parahemolyticus under gradual-low pH would probably inhibit disease outbreak in the shrimp farming. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Learning the scientific way of knowledge implies a change in the most implicit principles that guide comprehension, interpretation and explanation of scientific phenomena as well as a change in the type of associated reasoning. With the aim of favouring this type of learning, a teaching programme was developed in relation to vision and implemented with a group of secondary school students. The way of learning of these students was observed at different teaching stages. Findings suggest that during the learning process the way students learn seems to change gradually and that students construct “intermediate” models (right but incomplete that become the basis for the construction of a systemic model proposed by school science.

    Shantsev, D V; Goa, P E; Barkov, F L; Johansen, T H; Kang, W N; Lee, S I

    2003-01-01

    Magneto-optical imaging was used to study a zero-field-cooled MgB 2 film at 9.6 K where in a slowly increasing field the flux penetrates by an abrupt formation of large dendritic structures. Simultaneously, a gradual flux penetration takes place, eventually covering the dendrites, and a detailed analysis of this process is reported. We find an anomalously high gradient of the flux density across a dendrite branch, and a peak value that decreases as the applied field increases. This unexpected behaviour is reproduced by flux creep simulations based on the non-local field-current relation in the perpendicular geometry. The simulations also provide indirect evidence that flux dendrites are formed at an elevated local temperature, consistent with a thermo-magnetic mechanism of the instability

    Large volcanic eruptions on Earth commonly occur with a collapse of the roof of a crustal magma reservoir, forming a caldera. Only a few such collapses occur per century, and the lack of detailed observations has obscured insight into the mechanical interplay between collapse and eruption. We use multiparameter geophysical and geochemical data to show that the 110-square-kilometer and 65-meter-deep collapse of Bárdarbunga caldera in 2014-2015 was initiated through withdrawal of magma, and lateral migration through a 48-kilometers-long dike, from a 12-kilometers deep reservoir. Interaction between the pressure exerted by the subsiding reservoir roof and the physical properties of the subsurface flow path explain the gradual, near-exponential decline of both collapse rate and the intensity of the 180-day-long eruption.

    Full Text Available The paper presents the experimental results of some tests conducted with the purpose to gradually and cumulatively improve the classical DE scheme in both efficiency and success rate. The modifications consisted in the randomization of the scaling factor (a simple jitter scheme, a more efficient Random Greedy Selection scheme, an adaptive scheme for the crossover probability and a resetting mechanism for the agents. After each modification step, experiments have been conducted on a set of 11 scalable, multimodal, continuous optimization functions in order to analyze the improvements and decide the new improvement direction. Finally, only the initial classical scheme and the constructed Fast Self-Adaptive DE (FSA-DE variant were compared with the purpose of testing their performance degradation with the increase of the search space dimension. The experimental results demonstrated the superiority of the proposed FSA-DE variant.

    Full Text Available En este artículo se presenta el proceso gradual de construcción de tipos abstractos de datos (TADs, como los Fraccionarios y los Polinomios, a partir de TADs esenciales, como los Lógicos y los Enteros. Se propone un conjunto de categorías funcionales para clasificar las funciones de un TAD. Las funciones se especifican mediante programación funcional, es decir, no se utilizan construcciones estructuradas como la asignación, la secuencia y los ciclos. Hasta ahora no se encuentra reportada la especificación de funciones con programación funcional para la simplificación en el TAD de los Enteros ni para la suma ordenada en el TAD de los polinomios. Además se muestra la relación inherente entre las funciones de un TAD y la sobrecarga de operadores.

  3. An evolutionary perspective on gradual formation of superego in the primal horde

    2014-01-01

    Full Text Available Freud proposed that the processes which occurred in the primal horde are essential for understanding superego formation and therefore, the successful dissolution of the Oedipus complex. However, Freud theorized superego formation in the primal horde as if it is an instant, all-or-none achievement. The present paper proposes an alternative model aiming to explain gradual development of superego in the primitive man. The proposed model is built on knowledge from evolutionary and neural sciences as well as anthropology, and it particularly focuses on the evolutionary significance of the acquisition of fire by hominids in the Pleistocene period in the light of archaeological findings. Acquisition of fire is discussed as a form of sublimation which might have helped Prehistoric man to maximise the utility of limited evolutionary biological resources, potentially contributing to the rate and extent of bodily evolution. The limitations of both Freud's original conceptualisation and the present model are discussed accordingly in an interdisciplinary framework.

    By means of powder neutron diffraction we investigate changes in the magnetic structure of the coplanar noncollinear antiferromagnet Mn3Ge caused by an application of hydrostatic pressure up to 5 GPa. At ambient conditions the kagomé layers of Mn atoms in Mn3Ge order in a triangular 120∘ spin structure. Under high pressure the spins acquire a uniform out-of-plane canting, gradually transforming the magnetic texture to a noncoplanar configuration. With increasing pressure the canted structure fully transforms into the collinear ferromagnetic one. We observed that magnetic order is accompanied by a noticeable magnetoelastic effect, namely, spontaneous magnetostriction. The latter induces an in-plane magnetostrain of the hexagonal unit cell at ambient pressure and flips to an out-of-plane strain at high pressures in accordance with the change of the magnetic structure.

    On 1 April 2014, Northern Chile was struck by a magnitude 8.1 earthquake following a protracted series of foreshocks. The Integrated Plate Boundary Observatory Chile monitored the entire sequence of events, providing unprecedented resolution of the build-up to the main event and its rupture evolution. Here we show that the Iquique earthquake broke a central fraction of the so-called northern Chile seismic gap, the last major segment of the South American plate boundary that had not ruptured in the past century. Since July 2013 three seismic clusters, each lasting a few weeks, hit this part of the plate boundary with earthquakes of increasing peak magnitudes. Starting with the second cluster, geodetic observations show surface displacements that can be associated with slip on the plate interface. These seismic clusters and their slip transients occupied a part of the plate interface that was transitional between a fully locked and a creeping portion. Leading up to this earthquake, the b value of the foreshocks gradually decreased during the years before the earthquake, reversing its trend a few days before the Iquique earthquake. The mainshock finally nucleated at the northern end of the foreshock area, which skirted a locked patch, and ruptured mainly downdip towards higher locking. Peak slip was attained immediately downdip of the foreshock region and at the margin of the locked patch. We conclude that gradual weakening of the central part of the seismic gap accentuated by the foreshock activity in a zone of intermediate seismic coupling was instrumental in causing final failure, distinguishing the Iquique earthquake from most great earthquakes. Finally, only one-third of the gap was broken and the remaining locked segments now pose a significant, increased seismic hazard with the potential to host an earthquake with a magnitude of >8.5.

    Changes in climate, land management and fire regime have contributed to woody species expansion into grasslands and savannas worldwide. In the USA, Pinus ponderosa P.&C. Lawson and Juniperus virginiana L. are expanding into semiarid grasslands of Nebraska and other regions of the Great Plains. We examined P. ponderosa and J. virginiana seedling response to soil water content, one of the most important limiting factors in semiarid grasslands, to provide insight into their success in the region. Photosynthesis, stomatal conductance, maximum photochemical efficiency of PSII, maximum carboxylation velocity, maximum rate of electron transport, stomatal limitation to photosynthesis, water potential, root-to-shoot ratio, and needle nitrogen content were followed under gradual soil water depletion for 40 days. J. virginiana maintained lower L(s), higher A, g(s), and initial F(v)/F(m), and displayed a more gradual decline in V(cmax) and J(max) with increasing water deficit compared to P. ponderosa. J. virginiana also invested more in roots relative to shoots compared to P. ponderosa. F(v)/F(m) showed high PSII resistance to dehydration in both species. Photoinhibition was observed at approximately 30% of field capacity. Soil water content was a better predictor of A and g(s) than Psi, indicating that there are other growth factors controlling physiological processes under increased water stress. The two species followed different strategies to succeed in semiarid grasslands. P. ponderosa seedlings behaved like a drought-avoidant species with strong stomatal control, while J. virginiana was more of a drought-tolerant species, maintaining physiological activity at lower soil water content. Differences between the studied species and the ecological implications are discussed.

  7. Swarm of bees and particles algorithms in the problem of gradual failure reliability assurance

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Probability-statistical framework of reliability theory uses models based on the chance failures analysis. These models are not functional and do not reflect relation of reliability characteristics to the object performance. At the same time, a significant part of the technical systems failures are gradual failures caused by degradation of the internal parameters of the system under the influence of various external factors.The paper shows how to provide the required level of reliability at the design stage using a functional model of a technical object. Paper describes the method for solving this problem under incomplete initial information, when there is no information about the patterns of technological deviations and degradation parameters, and the considered system model is a \\black box" one.To this end, we formulate the problem of optimal parametric synthesis. It lies in the choice of the nominal values of the system parameters to satisfy the requirements for its operation and take into account the unavoidable deviations of the parameters from their design values during operation. As an optimization criterion in this case we propose to use a deterministic geometric criterion \\reliability reserve", which is the minimum distance measured along the coordinate directions from the nominal parameter value to the acceptability region boundary rather than statistical values.The paper presents the results of the application of heuristic swarm intelligence methods to solve the formulated optimization problem. Efficiency of particle swarm algorithms and swarm of bees one compared with undirected random search algorithm in solving a number of test optimal parametric synthesis problems in three areas: reliability, convergence rate and operating time. The study suggests that the use of a swarm of bees method for solving the problem of the technical systems gradual failure reliability ensuring is preferred because of the greater flexibility of the

  8. The signature of undetected change: an exploratory electrotomographic investigation of gradual change blindness.

    Neuroimaging-based investigations of change blindness, a phenomenon in which seemingly obvious changes in visual scenes fail to be detected, have significantly advanced our understanding of visual awareness. The vast majority of prior investigations, however, utilize paradigms involving visual disruptions (e.g., intervening blank screens, saccadic movements, "mudsplashes"), making it difficult to isolate neural responses toward visual changes cleanly. To address this issue in this present study, high-density EEG data (256 channel) were collected from 25 participants using a paradigm in which visual changes were progressively introduced into detailed real-world scenes without the use of visual disruption. Oscillatory activity associated with undetected changes was contrasted with activity linked to their absence using standardized low-resolution brain electromagnetic tomography (sLORETA). Although an insufficient number of detections were present to allow for analysis of actual change detection, increased beta-2 activity in the right inferior parietal lobule (rIPL), a region repeatedly associated with change blindness in disruption paradigms, followed by increased theta activity in the right superior temporal gyrus (rSTG) was noted in undetected visual change responses relative to the absence of change. We propose the rIPL beta-2 activity to be associated with orienting attention toward visual changes, with the subsequent rise in rSTG theta activity being potentially linked with updating preconscious perceptual memory representations. NEW & NOTEWORTHY This study represents the first neuroimaging-based investigation of gradual change blindness, a visual phenomenon that has significant potential to shed light on the processes underlying visual detection and conscious perception. The use of gradual change materials is reflective of real-world visual phenomena and allows for cleaner isolation of signals associated with the neural registration of change relative to the

    The regeneration of mouse testicular stem cells during 60 weeks after exposure to 600 or 1200 rad of γ radiation was examined. Restoration of spermatogenesis depended on stem cell survival, regeneration, and differentiation. Several assays were employed to measure the number of stem cells and their ability to repopulate the seminiferous epithelium as follows. Assay 1: The percentage of repopulated tubular cross sections was determined histologically at various times after irradiation. Assay 2: Mice were irradiated and, after given time intervals to allow for regeneration of stem cell numbers, a second dose was given. The percentage of repopulated tubular cross sections was determined 5 weeks later. Assay 3: The ability of the stem cells to produce spermatocytes and spermatids was assayed by the levels of the germ cell specific isoenzyme, LDH-X. Assay 4: The ability of the stem cells to produce sperm was assayed by the number of sperm heads in the testes. In addition, the ability of the stem cells to produce functional spermatozoa was measured by the fertility of the animals. The results obtained were as follows. All assays demonstrated that gradual regeneration of stem cell number occurred simultaneously with repopulation of the seminiferous epithelium by differentiating cells derived from stem cells. The regeneration kinetics of stem cells followed an exponential increase approaching a dose-dependent plateau below the level prior to irradiation. The doubling time for stem cells during the exponential portion was about 2 weeks. The regeneration of stem cell number after depletion by irradiation was gradual and incomplete, and only partially restored spermatogenesis. Correlation of regeneration with fertility data demonstrated that fertility was reestablished when sperm production returned to about 15% of control levels

    During recent decades various researchers from health and social sciences have been debating what it means for a person to be disabled. A rather overlooked approach has developed alongside this debate, primarily inspired by the philosophical tradition called phenomenology. This paper develops...... a phenomenological model of disability by arguing for a different methodological and conceptual framework from that used by the existing phenomenological approach. The existing approach is developed from the phenomenology of illness, but the paper illustrates how the case of congenital disabilities, looking...... at the congenital disorder called cerebral palsy (CP), presents a fundamental problem for the approach. In order to understand such congenital cases as CP, the experience of disability is described as being gradually different from, rather than a disruption of, the experience of being abled, and it is argued...

  6. Invisibility cloaks with arbitrary geometries for layered and gradually changing backgrounds

    International Nuclear Information System (INIS)

    Li, C; Yao, K; Li, F

    2009-01-01

    Cloaks with arbitrary geometries are proposed which can make objects invisible in inhomogeneous backgrounds. The general and explicit expressions of the complex permittivity and permeability tensors are derived for cloaks embedded in layered and gradually changing media. The inner and the outer boundaries of the cloaks can be non-conformal with arbitrary shapes, which considerably improve the flexibility of the cloak applications. The interactions of electromagnetic waves with irregular cloaks are studied based on numerical simulations. The influences of the cloaked and uncloaked perfect electric conductor (PEC) cylinders upon the scattering fields of the multilayered backgrounds are quantitatively evaluated. The effect of loss on the cloaking performance has also been investigated. It is verified that cloaks with ideal parameters can smoothly deflect and guide the incoming beams to propagate around the shielded regions without disturbing the beams when they return to the inhomogeneous backgrounds. Therefore, the objects in the shielded region can be effectively invisible to the corresponding backgrounds. The performance of lossy cloaks will degrade with comparatively large power reduction of the transmitted beams.

    30 keV O 2 + ions are implanted in aluminium foil, at various doses ranging from 5 x 10 16 to 5 x 10 17 atoms cm -2 . The sheet resistance was measured for unimplanted and implanted specimens. Up to the dose of 3 x 10 17 atoms cm -2 , the sheet resistance gradually increased. It formed a perfect insulating layer on the surface, above a dose of 3 x 10 17 atoms cm -2 . X-ray photo-electron spectroscopy measurements indicated the formation of an Al 2 O 3 layer with the absence of a signal due to unbonded aluminium for a dose of 5 x 10 17 atoms cm -2 . Whereas a specimen implanted at 5 x 10 16 atoms cm -2 shows the presence of pure aluminium. Micrographs of the specimen implanted at the higher dose displayed the microtopography characteristic of alumina. The results are in agreement with a recently published mechanism of Al 2 O 3 formation. The Al 2 O 3 precipitates increasing with dose and a layer of Al 2 O 3 being formed at the doses higher than that required to form the stoichiometric Al 2 O 3 . (author)

    Hu, J.; Li, G.

    2017-12-01

    Solar Energetic Particles (SEP) event is the number one space hazard for spacecraft instruments and astronauts' safety. Recent studies have shown that both longitudinal and radial extent of SEP events can be very significant. In this work, we use the improved Particle Acceleration and Transport in the Heliosphere (iPATH) model to simulate gradual SEP events that have impacts upon both the Earth and the Mars. We follow the propagation of a 2D CME-driven shock. Particles are accelerated at the shock via the diffusive shock acceleration (DSA) mechanism. Transport of the escaped particles to the Earth and the Mars is then followed using a backward stochastic differential equation method. Perpendicular diffusion is considered in both the DSA and the transport process. Model results such as time intensity profile and energetic particle spectrum at the two locations are compared to understand the spatial extent of an SEP event. Observational data at the Earth and the Mars are also studied to validate the model.

  9. Evolutionary characteristics of morbilliviruses during serial passages in vitro: Gradual attenuation of virus virulence.

    2016-08-01

    The genus Morbillivirus is classified into the family Paramyxoviridae, and is composed of 6 members, namely measles virus (MV), rinderpest virus (RPV), peste-des-petits-ruminants virus (PPRV), canine distemper virus (CDV), phocine distemper virus (PDV) and cetacean morbillivirus (CeMV). The MV, RPV, PPRV and CDV have been successfully attenuated through their serial passages in vitro for the production of live vaccines. It has been demonstrated that the morbilliviral virulence in animals was progressively attenuated with their consecutive passages in vitro. However, only a few reports were involved in explanation of an attenuation-related mechanism on them until many years after the establishment of a quasispecies theory. RNA virus quasispecies arise from rapid evolution of viruses with high mutation rate during genomic replication, and play an important role in gradual loss of viral virulence by serial passages. Here, we overviewed the development of live-attenuated vaccine strains against morbilliviruses by consecutive passages in vitro, and further discussed a related mechanism concerning the relationship between virulence attenuation and viral evolution.

  10. Gradual extinction prevents the return of fear: Implications for the discovery of state

    Directory of Open Access Journals (Sweden)

    Samuel Joseph Gershman

    2013-11-01

    Full Text Available Fear memories are notoriously difficult to erase, often recovering over time. The longstanding explanation for this finding is that, in extinction training, a new memory is formed that competes with the old one for expression but does not otherwise modify it. This explanation is at odds with traditional models of learning such as Rescorla-Wagner and reinforcement learning. A possible reconciliation that was recently suggested is that extinction training leads to the inference of a new state that is different from the state that was in effect in the original training. This solution, however, raises a new question: under what conditions are new states, or new memories formed? Theoretical accounts implicate persistent large prediction errors in this process. As a test of this idea, we reasoned that careful design of the reinforcement schedule during extinction training could reduce these prediction errors enough to prevent the formation of a new memory, while still decreasing reinforcement sufficiently to drive modification of the old fear memory. In two Pavlovian fear-conditioning experiments, we show that gradually reducing the frequency of aversive stimuli, rather than eliminating them abruptly, prevents the recovery of fear. This finding has important implications for theories of state discovery in reinforcement learning.

  12. Method for modeling the gradual physical degradation of a porous material

    Cementitious and other engineered porous materials encountered in waste disposals may degrade over time due to one or more mechanisms. Physical degradation may take the form of cracking (fracturing) and/or altered (e.g. increased) porosity, depending on the material and underlying degradation mechanism. In most cases, the hydraulic properties of degrading materials are expected to evolve due to physical changes occurring over roughly the pore to decimeter scale, which is conducive to calculating equivalent or effective material properties. The exact morphology of a degrading material in its end-state may or may not be known. In the latter case, the fully-degraded condition can be assumed to be similar to a more-permeable material in the surrounding environment, such as backfill soil. Then the fully-degraded waste form or barrier material is hydraulically neutral with respect to its surroundings, constituting neither a barrier to nor conduit for moisture flow and solute transport. Unless the degradation mechanism is abrupt, a gradual transition between the intact initial and fully-degraded final states is desired. Linear interpolation through time is one method for smoothly blending hydraulic properties between those of an intact matrix and those of a soil or other surrogate for the end-state.

    Civil structures and infrastructure facilities are susceptible to deterioration posed by the effects of natural hazards and aggressive environmental conditions. These factors may increase the risk of service interruption of infrastructures, and should be taken into account when assessing the structural reliability during an infrastructure's service life. Modeling the resistance deterioration process reasonably is the basis for structural reliability analysis. In this paper, a novel model is developed for describing the deterioration of aging structures. The deterioration is a combination of two stochastic processes: the gradual deterioration posed by environmental effects and the shock deterioration caused by severe load attacks. The dependency of the deterioration magnitude on the load intensity is considered. The Gaussian copula function is employed to help construct the joint distribution of correlated random variables. Semi-analytical methods are developed to assess the structural failure time and the number of significant load events (shocks) to failure. Illustrative examples are presented to demonstrate the applicability of the proposed model in structural reliability analysis. Parametric studies are performed to investigate the role of deterioration-load correlation in structural reliability. - Highlights: • A new resistance deterioration model for aging structures is proposed. • Time-dependent reliability analysis methods incorporating the proposed deterioration model are developed. • Parametric studies are performed to investigate the role of deterioration-load correlation in structural reliability.

    This paper examines the short run inefficiencies that arise during gradual implementation of a new cost-effective technology in healthcare. These inefficiencies arise when health gains associated with the new technology cannot be obtained immediately because the new technology does not yet supply all patients, and when there is overcapacity for the old technology in the short run because the supply of care is divided among two mutually exclusive technologies. Such efficiency losses are not taken into account in standard textbook cost-effectiveness analysis in which a steady state is presented where costs and effects are assumed to be unchanging over time. A model is constructed to quantify such short run inefficiencies as well as to inform the decision maker about the optimal implementation pattern for the new technology. The model operates by integrating the incremental net benefit equations for both the period of co-existence of mutually exclusive technologies and the period after complete substitution of the old technology. It takes into account the rate of implementation of the new technology, depreciation of capital of the old technology as well as the demand curves for both technologies. The model is applied to the real world case of converting from screen film to digital mammography in the Netherlands.

    As a multiphysics imaging approach, magnetoacoustic tomography with magnetic induction (MAT-MI) works on the physical mechanism of magnetic excitation, acoustic vibration, and transmission. Based on the theoretical analysis of the source vibration, numerical studies are conducted to simulate the pathological changes of tissues for a single-layer cylindrical conductivity gradual-varying model and estimate the strengths of sources inside the model. The results suggest that the inner source is generated by the product of the conductivity and the curl of the induced electric intensity inside conductivity homogeneous medium, while the boundary source is produced by the cross product of the gradient of conductivity and the induced electric intensity at conductivity boundary. For a biological tissue with low conductivity, the strength of boundary source is much higher than that of the inner source only when the size of conductivity transition zone is small. In this case, the tissue can be treated as a conductivity abrupt-varying model, ignoring the influence of inner source. Otherwise, the contributions of inner and boundary sources should be evaluated together quantitatively. This study provide basis for further study of precise image reconstruction of MAT-MI for pathological tissues.

  17. Method for modeling the gradual physical degradation of a porous material

    International Nuclear Information System (INIS)

    Flach, Greg

    2017-01-01

    Cementitious and other engineered porous materials encountered in waste disposals may degrade over time due to one or more mechanisms. Physical degradation may take the form of cracking (fracturing) and/or altered (e.g. increased) porosity, depending on the material and underlying degradation mechanism. In most cases, the hydraulic properties of degrading materials are expected to evolve due to physical changes occurring over roughly the pore to decimeter scale, which is conducive to calculating equivalent or effective material properties. The exact morphology of a degrading material in its end-state may or may not be known. In the latter case, the fully-degraded condition can be assumed to be similar to a more-permeable material in the surrounding environment, such as backfill soil. Then the fully-degraded waste form or barrier material is hydraulically neutral with respect to its surroundings, constituting neither a barrier to nor conduit for moisture flow and solute transport. Unless the degradation mechanism is abrupt, a gradual transition between the intact initial and fully-degraded final states is desired. Linear interpolation through time is one method for smoothly blending hydraulic properties between those of an intact matrix and those of a soil or other surrogate for the end-state.

    Is the energy equation for gradually-varied flow the best approximation for the free surface profile computations in river flows? Determination of flood inundation in rivers and natural waterways is based on the hydraulic computation of flow profiles. This is usually done using energy-based gradually-varied flow models, like HEC-RAS, that adopts a vertical division method for discharge prediction in compound channel sections. However, this discharge prediction method is not so accurate in the context of advancements over the last three decades. This paper firstly presents a study of the impact of discharge prediction on the gradually-varied flow computations by comparing thirteen different methods for compound channels, where both energy and momentum equations are applied. The discharge, velocity distribution coefficients, specific energy, momentum and flow profiles are determined. After the study of gradually-varied flow predictions, a new theory is developed to produce higher-order energy and momentum equations for rapidly-varied flow in compound channels. These generalized equations enable to describe the flow profiles with more generality than the gradually-varied flow computations. As an outcome, results of gradually-varied flow provide realistic conclusions for computations of flow in compound channels, showing that momentum-based models are in general more accurate; whereas the new theory developed for rapidly-varied flow opens a new research direction, so far not investigated in flows through compound channels.

    There is good reason to believe that the attitudes of persons without disability towards dating a person with a physical disability might be unfavourable. However, in general, and in the Global South in particular, there is a dearth of research in this area. This study sought to take the first step in addressing this lack of enquiry, by surveying the attitudes of a general population sample in South Africa towards dating people with physical disabilities, using a vignette. Data from 1723 survey respondents were analysed thematically. Findings reveal largely negative attitudes towards people with physical disabilities. Respondents without disability perceived numerous barriers to dating a person with a physical disability, including social stigma, anxiety and concerns about the burden of care they believed such a relationship would place upon them. However, there was some evidence to suggest that some positive attitudes do exist, and a few respondents were open to dating a person with physical disabilities. Findings contribute to a nuancing and expanding of the 'myth of asexuality' among physically disabled people by showing that people with physical disabilities are actively desexualised by persons without disability. Future research is needed to explore how the inclusive attitudes, of which we did find evidence here, can be further cultivated.

  20. When the Brain Takes 'BOLD' Steps: Real-Time fMRI Neurofeedback Can Further Enhance the Ability to Gradually Self-regulate Regional Brain Activation.

    Brain-computer interfaces (BCIs) based on real-time functional magnetic resonance imaging (rtfMRI) are currently explored in the context of developing alternative (motor-independent) communication and control means for the severely disabled. In such BCI systems, the user encodes a particular intention (e.g., an answer to a question or an intended action) by evoking specific mental activity resulting in a distinct brain state that can be decoded from fMRI activation. One goal in this context is to increase the degrees of freedom in encoding different intentions, i.e., to allow the BCI user to choose from as many options as possible. Recently, the ability to voluntarily modulate spatial and/or temporal blood oxygenation level-dependent (BOLD)-signal features has been explored implementing different mental tasks and/or different encoding time intervals, respectively. Our two-session fMRI feasibility study systematically investigated for the first time the possibility of using magnitudinal BOLD-signal features for intention encoding. Particularly, in our novel paradigm, participants (n=10) were asked to alternately self-regulate their regional brain-activation level to 30%, 60% or 90% of their maximal capacity by applying a selected activation strategy (i.e., performing a mental task, e.g., inner speech) and modulation strategies (e.g., using different speech rates) suggested by the experimenters. In a second step, we tested the hypothesis that the additional availability of feedback information on the current BOLD-signal level within a region of interest improves the gradual-self regulation performance. Therefore, participants were provided with neurofeedback in one of the two fMRI sessions. Our results show that the majority of the participants were able to gradually self-regulate regional brain activation to at least two different target levels even in the absence of neurofeedback. When provided with continuous feedback on their current BOLD-signal level, most

    It is intuitive that disability caused by illness should be reflected in illness severity. Because disability rates for fibromyalgia (FM) are high in the developed world, we have examined disease and work characteristics for patients with FM who were working, unemployed, or receiving disability payments for disability as a result of FM. Of the 248 participants in a tertiary care cohort study of patients with FM, 90 were employed, 81 were not employed and not receiving disability payments, and 77 were not working and currently receiving disability payments awarded for disability caused by FM. Demographic, occupation, and disease characteristics were compared among the groups. The prevalence of disability caused by FM was 30.8%. There were no demographic differences among the working, unemployed, or disabled patients. With the exception of measures for anxiety and depression, all measurements for disease severity differed significantly among the groups, with greater severity reported for the disabled group, which used more medications and participated less in physical activity. Disabled patients were more likely previously employed in manual professions or the service industry, whereas employed patients were more commonly working in non-manual jobs that included clerical, managerial, or professional occupations (p = 0.005). The one-third rate of disability for this Canadian cohort of patients with FM is in line with other reports from the western world. Associations of disability compensation were observed for subjective report of symptom severity, increased use of medications, and previous employment in more physically demanding jobs.

    To investigate the inclusion of people with disabilities in the diversity policies of the most successful businesses in the United States, we examined the publicly available workforce and supplier diversity policies of the top 100 companies on Fortune Magazine's 2003 list of the 500 most profitable companies in the nation. The majority of these companies have extensive information about their diversity policies and practices available on their corporate website. The information was used to categorize the policies into those that include people with disabilities, do not define diversity, and enumerate what is meant by diversity (e.g. in terms of race or gender) but do not expressly mention disability. In addition, we looked beyond the diversity policies to information available on corporate websites relating to a variety of diversity initiatives. Findings suggest that the majority of the companies that top the Fortune 500 list have developed and implemented diversity policies. Of these, 42% have diversity policies that include people with disabilities in the definition of a diverse workforce. Furthermore, 47% of companies with workplace diversity policies discuss diversity in a way that neither expressly includes nor excludes people with disabilities. Far fewer (15%) supplier diversity policies include disability in the definition of diversity, but a significant number of companies use criteria that allow a business owner with a disability to benefit from the company's supplier diversity program. 2005 John Wiley & Sons, Ltd.

    Full Text Available This article sets out to increase awareness regarding the wide and universal significance of disability, as well as the important benefits of an Integrated Disability Management (IDM approach. The scientific basis for IDM is explored in the first place through an analysis of its relationship to the International Classification of Functioning, Disability and Health (ICF. The conceptual paradigm of the ICF shares an ideological position with the IDM approach in that they are both underpinned by dynamic and multidimensional constructions of disability, which imply equally holistic and interdisciplinary responses. The IDM approach can be applied across a diversity of human situations to provide solutions that reflect the multifaceted and widespread nature of disability. The IDM approach is intended as a strategy capable of handling: inclusion of people with disabilities, active aging of human resources, health and safety in the workplace, prevention of disabilities and various diseases, return-to-work, absenteeism, and presenteeism.

    Full Text Available Ways of thinking about and responding to disability have radically changed in recent decades. Traditionally, disability was regarded in terms of sin, karma, or divine punishment. More recently, disability was made a medical issue and defined in terms of shortcomings of body or mind, which had to be prevented or cured at all costs. In the late 20th century, people with disabilities worldwide became more organised and created national and international disabled people’s organisations. They successfully demanded that disability be seen as a matter of equal opportunities and human rights, a shift which has now been described in the United Nations Convention on the Rights of Persons with Disabilities. This is a global treaty which has so far been signed by 155 states and passed into law by 127.

    Full Text Available Developmental disabilities consist of conditions that delay or impair the physical, cognitive, and/or psychological development of children. If not intervened at the earliest, these disabilities will cause significant negative impact on multiple domains of functioning such as learning, language, self-care and capacity for independent living. Common developmental disabilities include autism spectrum disorders, intellectual disabilities, developmental delay and cerebral palsy. About one fourth of young children in developing countries are at risk for or have developmental delay or disabilities. Inadequate stimulation has significant negative impact on physical, socioemotional and cognitive development of children. Hence early scientific intervention programs are necessary in the management of children at risk for developmental delay.

    Estrogen replacement therapy in Turner syndrome should theoretically mimic the physiology of healthy girls. The objective of this study was to describe final height and bone mineral density (BMD) in a group of 17 Turner syndrome patients (group E) who started their ethinyl estradiol therapy with an ultra-low dosage (1-5 ng/kg/day) from 9.8-13.7 years. The subjects in group E had been treated with GH 0.35 mg/kg/week since the average age of 7.4 years. The 30 subjects in group L, one of the historical groups, were given comparable doses of GH, and conjugated estrogen 0.3125 mg/week ∼0.3125 mg/day was initiated at 12.2-18.7 years. The subjects in group S, the other historical group, were 21 patients who experienced breast development and menarche spontaneously. Final height (height gain Turner syndrome. The final height in group L was 148.5 ± 3.0 cm with a SD of 1.30 ± 0.55, which was significantly different from the values for group E. The volumetric BMD of group S (0.290 ± 0.026 g/cm 3 ) was significantly different from that of group L or E (0.262 or 0.262 g/cm 3 as a mean, respectively). This is the first study of patients with Turner syndrome where estrogen was administered initially in an ultra-low dose and then increased gradually. Our estrogen therapy in group E produced good final height but not ideal BMD.

    To be bedridden is a common phenomenon in nursing. However, there is no solid base of knowledge on reasons, types, development of and coping with this situation. The concept of being bedridden is applied in an arbitrary manner and the state of being bedridden is far from being clearly defined. A literature review revealed that only pathophysiological effects of this state are sufficiently explained. The aim of this study was to gain knowledge of the development of being confined to bed. Thirty-two interviews with elderly, bedridden people (nineteen women, thirteen men) were conducted. They were asked about their perspective on and their experience of the development of being confined to bed. Half of the interviewees lived in a nursing home, the others were cared for at home. Data collection and analysis were performed by using a Grounded Theory approach as developed by Strauss and Corbin. "Gradual local fixation" was identified as the core category. Becoming bedridden is a slow process by which the person is increasingly confined to one location. This development is related to an increasing need for support and to negative consequences such as a pathology of immobility, narrowing of interests, and loss of time. These consequences again are responsible for a downward spiral development. This study reveals phases of development and a range of factors influencing them. Many of these factors arise from the person and his/her interactional behaviour in the circumstances, other influences are structural factors such as external pressure caused by time constraints of professional nursing services or unfavourable arrangements of furniture. A lot of factors of being confined to bed are changeable. Long periods of being bedridden can be prevented in many cases, if early warning signs are being recognized and preventive measures are taken in time.

  8. Rapid and gradual modes of aerosol trace metal dissolution in seawater

    Full Text Available Atmospheric deposition is a major source of trace metals in marine surface waters and supplies vital micronutrients to phytoplankton, yet measured aerosol trace metal solubility values are operationally defined and there are relatively few multi-element studies on aerosol-metal solubility in seawater. Here we measure the solubility of aluminum (Al, cadmium (Cd, cobalt (Co, copper (Cu, iron (Fe, manganese (Mn, nickel (Ni, lead (Pb, and zinc (Zn from natural aerosol samples in seawater over a 7 day period to (1 evaluate the role of extraction time in trace metal dissolution behavior and (2 explore how the individual dissolution patterns could influence biota. Dissolution behavior occurs over a continuum ranging from rapid dissolution, in which the majority of soluble metal dissolved immediately upon seawater exposure (Cd and Co in our samples, to gradual dissolution, where metals dissolved slowly over time (Zn, Mn, Cu, and Al in our samples. Additionally, dissolution affected by interactions with particles was observed in which a decline in soluble metal concentration over time occurred (Fe and Pb in our samples. Natural variability in aerosol chemistry between samples can cause metals to display different dissolution kinetics in different samples, and this was particularly evident for Ni, for which samples showed a broad range of dissolution rates. The elemental molar ratio of metals in the bulk aerosols was 23,189Fe: 22,651Al: 445Mn: 348Zn: 71Cu: 48Ni: 23Pb: 9Co: 1Cd, whereas the seawater soluble molar ratio after 7 days of leaching was 11Fe: 620Al: 205Mn: 240Zn: 20Cu: 14Ni: 9Pb: 2Co: 1Cd. The different kinetics and ratios of aerosol metal dissolution have implications for phytoplankton nutrition, and highlight the need for unified extraction protocols that simulate aerosol metal dissolution in the surface ocean.

    The precise dynamics of breakdown in pipe transition is a century-old unresolved problem in fluid mechanics. We demonstrate that the abruptness and mysteriousness attributed to the Osborne Reynolds pipe transition can be partially resolved with a spatially developing direct simulation that carries weakly but finitely perturbed laminar inflow through gradual rather than abrupt transition arriving at the fully developed turbulent state. Our results with this approach show during transition the energy norms of such inlet perturbations grow exponentially rather than algebraically with axial distance. When inlet disturbance is located in the core region, helical vortex filaments evolve into large-scale reverse hairpin vortices. The interaction of these reverse hairpins among themselves or with the near-wall flow when they descend to the surface from the core produces small-scale hairpin packets, which leads to breakdown. When inlet disturbance is near the wall, certain quasi-spanwise structure is stretched into a Lambda vortex, and develops into a large-scale hairpin vortex. Small-scale hairpin packets emerge near the tip region of the large-scale hairpin vortex, and subsequently grow into a turbulent spot, which is itself a local concentration of small-scale hairpin vortices. This vortex dynamics is broadly analogous to that in the boundary layer bypass transition and in the secondary instability and breakdown stage of natural transition, suggesting the possibility of a partial unification. Under parabolic base flow the friction factor overshoots Moody's correlation. Plug base flow requires stronger inlet disturbance for transition. Accuracy of the results is demonstrated by comparing with analytical solutions before breakdown, and with fully developed turbulence measurements after the completion of transition.

    Full Text Available Field study was carried out in 2011 in west of Iran to assess responses of dry bean (Phaseolus vulgaris L. morpho-physiological traits to gradual weed biomass accumulation. The treatments consisted of two different periods of weed interference, which weeds either infested the plots or removed for an increasing duration of time (0, 10, 20, 30, 40, 50 days after crop emergence. Relative dominance and relative importance of weed species fluctuated over the crop cycle. As the duration of weed interference was increased, a declining trend of crop growth rate (CGR was observed. When weeds were allowed to compete with crop throughout the crop cycle, maximum value of CGR was decreased from 25.57 g m-2 days in full season weed free treatment to 16.78 g m-2 days in full season weed infested treatment. Effect of treatments on leaf area index (LAI was significant. Weed removal increased LAI but it could not significantly affect this trait, at the early of growing season. Weed interference caused a significant reduction on number of branches. The minimum number of branches was registered in full season weed infested treatment (2.58 branches per plant, while the maximum one was observed in the full season weed free treatment (4.25 branches per plant. Weed competition severely reduced crop yield. At 10 and 20 days after crop emergence, weed infestation could not significantly affect the yield. A negative relationship between weeds’ dry matter accumulation and LAI as well as number of branches was observed which signify the vulnerability of these morpho-physiological traits to weed competition.

    All physicians will care for individuals with disabilities; however, education about disabilities is lacking at most medical schools. Most of the schools that do include such education exclusively teach the medical model, in which disability is viewed as an impairment to be overcome. Disability advocates contest this approach because it overlooks the social and societal contexts of disability. A collaboration between individuals with disabilities, educators, and physicians to design a medical school curriculum on disabilities could overcome these differences. A curriculum on disabilities for first- and second-year medical students was developed during the 2013-2014 academic year and involved a major collaboration between a medical student, medical educators, disability advocates, and academic disability specialists. The guiding principle of the project was the Disability Rights Movement motto, "Nothing about us without us." Two small-group sessions were created, one for each medical school class. They included discussions about different models of disability, video and in-person narratives of individuals with disabilities, and explorations of concepts central to social perceptions of disability, such as power relationships, naming and stigmatization, and disability as identity. According to evaluations conducted after each session, students reported positive feedback about both sessions. Through this curriculum, first- and second-year medical students learned about the obstacles faced by individuals with disabilities and became better equipped to understand and address the concerns, hopes, and societal challenges of their future patients. This inclusive approach may be used to design additional curricula about disabilities for the clinical and postgraduate years.

    Advances in research on disability and rehabilitation are essential to creating equal opportunity, economic self-sufficiency, and full participation for persons with disabilities. Historically, such initiatives have focused on separate and specific areas, including neuroscience, molecular biology and genetics, gerontology, engineering and physical sciences, and social and behavioral sciences. Research on persons with disabilities should examine the broader context and trends of society that affect the total environment of persons with disabilities. This article examines the various disability paradigms across time, assessing the relative contribution of the socioecological perspective in guiding research designed to improve the lives of persons with disabilities. The authors recommend new research directions that include a focus on life span issues, biomedicine, biotechnology, the efficacy and effectiveness of current interventions, an emphasis on consumer-driven investigations within a socioecological perspective of disability, and the implications for research and practice.

  18. Assessment of Integration of Disability Content into Social Work Education.

    Three hundred members of the Council on Social Work Education (CSWE) responded to a survey regarding the inclusion of disability content in social work courses and supports needed to increase disability content. Although respondents generally agreed that disability content is important in social work education, its inclusion is inconsistent, with most frequent inclusion in courses on diversity and least frequent inclusion in courses on research. Respondents identified barriers to increasing disability content, including lack of resources for teaching, lack of relevant faculty expertise, and an overcrowded curriculum. Strategies and resources for infusing disability content into social work education are discussed.

    Numerical simulation of differential equation systems plays a major role in the understanding of how metabolic network models generate particular cellular functions. On the other hand, the classical and technical problems for stiff differential equations still remain to be solved, while many elegant algorithms have been presented. To relax the stiffness problem, we propose new practical methods: the gradual update of differential-algebraic equations based on gradual application of the steady-state approximation to stiff differential equations, and the gradual update of the initial values in differential-algebraic equations. These empirical methods show a high efficiency for simulating the steady-state solutions for the stiff differential equations that existing solvers alone cannot solve. They are effective in extending the applicability of dynamic simulation to biochemical network models.

    Obesity is associated with adverse health outcomes in people with and without disabilities. However, little is known about disability prevalence among people who are obese. The purpose of this study is to determine the prevalence and type of disability among adults who are obese. Pooled data from the 2003-2009 National Health Interview Survey (NHIS) were analyzed to obtain national prevalence estimates of disability, disability type and obesity. The disability prevalence was stratified by body mass index (BMI): healthy weight (BMI 18.5-reported a disability. In contrast, 26.7% of those with a healthy weight and 28.5% of those who were overweight reported a disability. The most common disabilities among respondents with obesity were movement difficulty (32.5%) and work limitation (16.6%). This research contributes to the literature on obesity by including disability as a demographic in assessing the burden of obesity. Because of the high prevalence of disability among those who are obese, public health programs should consider the needs of those with disabilities when designing obesity prevention and treatment programs.

  1. Why Bioethics Needs a Disability Moral Psychology.

    Science.gov (United States)

    Stramondo, Joseph A

    2016-05-01

    The deeply entrenched, sometimes heated conflict between the disability movement and the profession of bioethics is well known and well documented. Critiques of prenatal diagnosis and selective abortion are probably the most salient and most sophisticated of disability studies scholars' engagements with bioethics, but there are many other topics over which disability activists and scholars have encountered the field of bioethics in an adversarial way, including health care rationing, growth-attenuation interventions, assisted reproduction technology, and physician-assisted suicide. The tension between the analyses of the disabilities studies scholars and mainstream bioethics is not merely a conflict between two insular political groups, however; it is, rather, also an encounter between those who have experienced disability and those who have not. This paper explores that idea. I maintain that it is a mistake to think of this conflict as arising just from a difference in ideology or political commitments because it represents a much deeper difference-one rooted in variations in how human beings perceive and reason about moral problems. These are what I will refer to as variations of moral psychology. The lived experiences of disability produce variations in moral psychology that are at the heart of the moral conflict between the disability movement and mainstream bioethics. I will illustrate this point by exploring how the disability movement and mainstream bioethics come into conflict when perceiving and analyzing the moral problem of physician-assisted suicide via the lens of the principle of respect for autonomy. To reconcile its contemporary and historical conflict with the disability movement, the field of bioethics must engage with and fully consider the two groups' differences in moral perception and reasoning, not just the explicit moral and political arguments of the disability movement. © 2016 The Hastings Center.

  2. Categorizing clients with disabilities

    DEFF Research Database (Denmark)

    Kjeldsen, Lena; Amby, Finn

    Danish governments have continuously proclaimed goals of raising the employment rate for people with disabilities, most recently in the publication “10 goal for social mobility” (Government 2016). In spite of this, the employment rate for people with disabilities has been more than 30 percent less...... than that of people without disabilities for more than a decade (Larsen & Høgelund 2015). An explanation of this difference could be the limited connection between these general goals, the employment laws and the actual implementation of the goals in the job centers (Amby 2015). Earlier Danish studies...... have by large focused on employment and disability at the stage where the client already has been categorized as having a disability (e.g. Møller & Stone 2013). This study offers new insight to the field in a Danish context by exploring the process in which people with disabilities are categorized...

    Touch screens are becoming more prevalent in everyday environments. Therefore, it is important that this technology is accessible to those with varying disabilities. The objective of the current study was to evaluate performance and touch characteristics (forces, impulses, and dwell times) of individuals with and without a movement disorder during a reciprocal tapping touch screen task. Thirty-seven participants with a motor control disability and 15 non-disabled participants participated. Outcome measures include number of correct taps, dwell time, exerted force, and impulse. Results indicate non-disabled participants had 1.8 more taps than participants with fine motor control disabilities and 2.8 times more than those with gross motor impairments (ptouch characteristics exist between those with and without motor control disabilities. Understanding how people (including those with disabilities) interact with touch screens may allow designers and engineers to ultimately improve usability of touch screen technology.

    To understand the potential impacts of China's accession to WTO in her new de-sulfur policy (gradual reduction of 10% of annual SO2 emission by 2005 with respect to that of 2000), we construct a CGE model in which SO2 emission is directly linked to energy input consumption in production. The model equally considers the substitution possibility between energies of different SO2 effluent ratio by including energy as traditional production factor as labor and capital in the constant elasticity o...

    This Paper studies the design of retirement and disability policies. It illustrates the often observed exit from the labour force of healthy workers through disability insurance schemes. Two types of individuals, disabled and leisure-prone ones, have the same disutility for labour and cannot be distinguished. They are not, however, counted in the same way in social welfare. Benefits depend on retirement age and on the (reported) health status. We determine first- and second-best optimal benef...

  6. Disability: a voice in Australian bioethics?

    Science.gov (United States)

    Newell, Christopher

    2003-06-01

    The rise of research and advocacy over the years to establish a disability voice in Australia with regard to bioethical issues is explored. This includes an analysis of some of the political processes and engagement in mainstream bioethical debate. An understanding of the politics of rejected knowledge is vital in understanding the muted disability voices in Australian bioethics and public policy. It is also suggested that the voices of those who are marginalised or oppressed in society, such as people with disability, have particular contribution to make in fostering critical bioethics.

  7. Working while on a disability pension in Finland: Association of diagnosis and financial factors to employment.

    2018-02-01

    The aim of this study was to find out whether health and financial factors are associated with engagement in paid work during a disability pension. The data included a 10 per cent sample of Finns aged 20-62 years who were drawing earnings-related full or partial disability pension in 2012 ( n = 14,418). Logistic regression analysis was used to estimate odds ratios for working while on a full or partial disability pension. Fourteen per cent of full disability pensioners and 76 per cent of partial disability pensioners were engaged in paid work. Full disability pensioners due to mental disorders were working less often than full disability pensioners due to other diseases. Partial disability pensioners due to cardiovascular diseases were working more than partial disability pensioners due to other diseases. More recent timing of disability pension was associated with working for both partial and full disability pensioners. Working while on disability pension was more common among those with higher education. Partial disability pensioners with average pension worked more often than those with high pension. By knowing the factors associated with working while on a disability pension, policies could be more efficiently allocated to encourage disability pensioners to take up work. One way would be to support disability pensioners with low education to work more. Another way to increase work among disability pensioners is to support the recently retired in working longer.

  8. The Brazilian education system. Students with disabilities

    Directory of Open Access Journals (Sweden)

    Roberto Dainese

    2010-07-01

    Full Text Available The Brazilian education system provides a specific form of organization for the inclusive education of students with disabilities. Law No. 9394 dated December 20, 1996, “Lei de diretrizes e bases da educação nacional”, presents in Chapter V the “educação especial" as a form of organization offered to students "portadores de Necessidades especiais”. Admission of students with disabilities in the Brazilian schools was characterized by several phases: the welfarist phase, the integration phase and the inclusion phase, which is the most recent one and now being debated. The presence of a special device fosters the differences, even when everybody enters the classbecause a separation perspective damps down all the procedural and design efforts towards a true integration, holding back collaboration and action sharing among teachers. We consider however effective an action that accompanies the gradual learning evolution mediating between the student with disabilities and peers, between him and the teachers, between him and the learning tools designed.

  9. Disability and the post-2015 development agenda.

    Science.gov (United States)

    Tardi, Rachele; Njelesani, Janet

    2015-01-01

    The article considers the extent to which disability has been recognized and included in two main documents produced to date as part of the United Nations Post-2015 Development agenda process. This is the process that is defining the Sustainable Development Goals (SDGs), which will succeed the UN Millennium Development Goals (MDGs) after the latter reach their target date in 2015. The two documents examined in the article are the Outcome Document (July 2014) of the Open Working Group (OWG) on SDGs and the Report (August 2014) of the Intergovernmental Committee of Experts on Sustainable Development Financing (ICESDF). The OWG consisted of 30 seats shared by 70 UN Member States and was in charge of proposing goals and targets for the SDGs. The ICESDF worked in parallel to the OWG and its report proposed options on an effective financing strategy. The article emphasizes the importance of including persons with disabilities in the Post-2015 Agenda, especially in view of the latter's overarching focus on eradicating poverty. The inclusion of persons with disabilities is being recognized in the Post-2015 Agenda discussions as central to achieving sustainable development. Disability has been explicitly mentioned in the OWG and ICESDF documents. Although the results so far have been very good, more work still needs to be done to ensure that these explicit references are maintained in the final version of the SDGs, which will be adopted in September 2015. Furthermore, the new framework needs to have a stronger human rights foundation on which to ground these references and future indicators. Light for the World is an international confederation of national development non-governmental organizations (NGOs) aiming at an inclusive society, where the rights of persons with disabilities are realized without discrimination. Through a rights-based approach, Light for the World supports 175 programs in 25 countries in the areas of prevention of blindness, rehabilitation, inclusive

    Grenier, Michelle; Collins, Karen; Wright, Steven; Kearns, Catherine

    2014-01-01

    The purpose of this qualitative study was to assess the effectiveness of a disability sport unit in shaping perceptions of disability. Data from interviews, observations, and documents were collected on 87 elementary-aged students, one physical education teacher, and one teaching intern. Comparisons were drawn between fifth graders engaged in a five-week disability sport unit to fourth graders participating in their standard physical education curriculum. Findings revealed differences in the way fourth and fifth graders came to view individuals with disabilities. The results support an analysis of curriculum development that underscores the significance of the social model in positively impacting constructions of disability. Recommendations include the use of disability sports in physical education as an effective strategy for educating students in game play, knowledge of the Paralympics, and the inclusion of individuals with disabilities in a variety of sporting venues.

  14. Identification and assessment of students with disabilities.

    Science.gov (United States)

    Reschly, D J

    1996-01-01

    Students with disabilities or suspected disabilities are evaluated by schools to determine whether they are eligible for special education services and, if eligible, to determine what services will be provided. In many states, the results of this evaluation also affect how much funding assistance the school will receive to meet the students' special needs. Special education classification is not uniform across states or regions. Students with identical characteristics can be diagnosed as disabled in one state but not in another and may be reclassified when they move across state or school district lines. Most disabilities with a clear medical basis are recognized by the child's physician or parents soon after birth or during the preschool years. In contrast, the majority of students with disabilities are initially referred for evaluation by their classroom teacher (or parents) because of severe and chronic achievement or behavioral problems. There is evidence that the prevalence of some disabilities varies by age, the high-incidence disabilities such as learning disabilities and speech-language disabilities occur primarily at the mild level, the mild disabilities exist on broad continua in which there are no clear demarcations between those who have and those who do not have the disability, and even "mild" disabilities may constitute formidable barriers to academic progress and significantly limit career opportunities. Problems with the current classification system include stigma to the child, low reliability, poor correlation between categorization and treatment, obsolete assumptions still in use in treatment, and disproportionate representation of minority students. Both African-American and Hispanic students are disproportionately represented in special education but in opposite directions. The disproportionately high number of African Americans in special education reflects the fact that more African-American students than white students are diagnosed with

  15. Children with intellectual disability and hospice utilization.

    2017-02-01

    Over 42,000 children die each year in the United States, including those with intellectual disability (ID). Survival is often reduced when children with intellectual disability also suffer from significant motor dysfunction, progressive congenital conditions, and comorbidities. Yet, little is known about hospice care for children with intellectual disability. The purpose of this study was to explore the relationship between intellectual disability and hospice utilization. Additionally, we explored whether intellectual disability combined with motor dysfunction, progressive congenital conditions, and comorbidities influenced pediatric hospice utilization. Using a retrospective cohort design and data from the 2009 to 2010 California Medicaid claims files, we conducted a multivariate analysis of hospice utilization. This study shows that intellectual disability was negatively related to hospice enrollment and length of stay. We also found that when children had both intellectual disability and comorbidities, there was a positive association with enrolling in hospice care. A number of clinical implications can be drawn from the study findings that hospice and palliative care nurses use to improve their clinical practice of caring for children with ID and their families at end of life.

    Full Text Available The purpose of this study was to determine sexual functioning of Polish athletes with disabilities (including paralympians. The study encompassed 218 people with physical disabilities, aged between 18 and 45 (149 men and 69 women. The entire research population was divided into three groups: Polish paralympians (n = 45, athletes with disabilities (n = 126 and non-athletes with disabilities (n = 47. The quality of sexual life of Polish paralympians was measured by using the Polish version of Female Sexual Function Index and International Index of Erectile Function. Clinically significant erectile dysfunctions were most often diagnosed in non-athletes (83.33% with 50% result of severe erectile dysfunctions, followed by athletes and paralympians with comparable results of 56.98% and 54.17% respectively (p = 0.00388. Statistically significant clinical sexual dysfunctions concerned lubrication, orgasm as well as pain domains, and prevailed among female non-athletes (68.42%, 68.42% and 57.89%. Practising sports at the highest level has a favourable effect on the sexuality of men and women with physical disabilities. Men with physical disabilities manifest more sexual disorders than women, an aspect which should be considered by health-care professionals working with people with disabilities.

    2017-11-10

    The media plays an important role in shaping society's beliefs about disability and sport. The aim of this systematic review is to identify how elite athletes with disability are portrayed in the media. Six electronic databases were searched from 2001 to March 2017 for quantitative or qualitative content analysis of media coverage of elite athletes with disability: SportsDiscus, CINAHL, PsychInfo, Medline 1996-, Embase, and Proquest. Quality assessment and data extraction were performed by two independent assessors. Seventeen moderate quality articles were included. Six themes emerged from the data such as frequency of articles and photos about elite athletes with disability; athlete gender; athlete nationality; disability; athleticism; and Olympic Games versus Paralympic Games. Our results show that elite athletes with disability are less visible in the media than their nondisabled counterparts; female athletes received less coverage than male; the media favored domestic athletes and certain types of disability; and, although there was a focus on athleticism, this was underpinned by a "supercrip" narrative and a medicalised description of disability. Although there has been a positive shift in the narrative around elite athletes with disability in media, relative absence and differing portrayal is present. Considering the power of media shaping society's perceptions of disability, further investigation is warranted. Implications for Rehabilitation Media has a role in how elite athletes with disability are portrayed and consequently perceived by the public. Elite athletes with disability rarely feature in media. Images of disability are minimized, and certain types of disabilities are favored. An athletic narrative is emerging; however, a medicalised description of athletes remains, shifting the focus from athleticism. "Supercrip" and "Superhuman" terms are commonly used, but may negatively impact the broader disability community.

    Rethemeyer, Janet; Kröpelin, Stefan; Karls, Jens; Thienemann, Matthias; Melles, Martin; Schefuß, Enno

    2014-05-01

    It is still an ongoing debate whether the transition of the last 'green Sahara' period to today's large desert during the Holocene, the African Humid Period (AHP), was a progressive or an abrupt change in hydrological conditions. Several climate records mainly from East Africa suggest a rapid decline of moisture availability at the end of the AHP including new data from a marine sequence off the Horn of Africa (Tierney & deMenocal, 2013). Other archives including sedimentological, geochemical and palynological data from the central North African Lakes Chad and Lake Yoa point to a gradual rather than an abrupt transition near 5,000 years ago (Amaral et al., 2013; Kröpelin et al., 2008). The discrepancy of the available paleo-hydrological reconstructions underline the importance of proxy parameters directly related to hydrological conditions for accurate assessment of continental rainfall changes. Here, we present the first molecular-isotopic data from Lake Yoa documenting the hydrologic evolution over the entire Holocene. Compound-specific carbon and hydrogen isotope analyses were performed on long-chain n-alkanes. Our data indicate relative high but variable contributions of plant-derived long-chain n-alkanes carrying a distinct leaf-wax signature, i.e., a high Carbon Preference Index (CPI). A trend towards higher CPI values since 7,300 years ago suggests declining soil degradation and vegetation cover under increasingly drier conditions. In parallel, the average-chain-length of the long-chain n-alkanes increases gradually towards the present implying higher relative contributions from grasses. Compound-specific carbon isotope data confirm this finding, indicating a mixed C3/C4 contribution in the early and mid-Holocene changing towards a C4-grass dominated vegetation in the late Holocene. Most importantly, compound-specific hydrogen isotope data reveal a continuous increase from 8,100 years ago towards the present, reflecting a gradual aridification. The large

    Salter, Erica K

    2017-09-01

    From growth attenuation therapy for severely developmentally disabled children to the post-natal management of infants with trisomy 13 and 18, pediatric treatment decisions regularly involve assessments of the probability and severity of a child's disability. Because these decisions are almost always made by surrogate decision-makers (parents and caregivers) and because these decision-makers must often make decisions based on both prognostic guesses and potentially biased quality of life judgments, they are among the most ethically complex in pediatric care. As the introduction to HEC Forum's special thematic issue on Childhood and Disability, this article orients the reader to the history of bioethics' relationship to both pediatric ethics and disability studies and introduces the issue's five manuscripts. As clinicians, disability scholars, philosophers and clinical ethicists writing on various aspects of pediatric disability, the articles' authors all invite readers to dig beneath an overly-simplified version of what disability might mean to children and families and instead embrace a posture of genuine humility, recognizing both the limits and harms of traditional medical and bioethical responses (or indifferences) to the disabled child.

  5. Creating a disability mythology.

    Brown, S E

    1992-01-01

    People with disabilities have, for the most part, failed to identify with each other as a group. This has been detrimental because it has built a sense of isolation when a camaraderie based upon existing commonalities could have been developed. During the past ten to twenty years, there has been a great deal of discussion about appropriate language to use when discussing disability issues. This discussion has been a part of a larger debate concerning the existence of a disability culture. I believe that there is indeed a disability culture and I am a proponent of identifying and passing on stories which contribute to that culture. I have chosen to use mythology to convey this message and have begun with a focus on heroes - people who do something out of the ordinary. It is contended that almost all people with disabilities have performed heroic activities because of the pervasive discrimination encountered by each individual with a disability. Creating a disability mythology is an attempt to recognize and promote heroes within the disabled community and to advocate the importance of telling other people how positive change has occurred through instances of individual heroism.

  8. Defining Disability: Understandings of and Attitudes Towards Ableism and Disability

    Directory of Open Access Journals (Sweden)

    2017-03-01

    Full Text Available Disabled people, amidst political and social gains, continue to experience discrimination in multiple areas. Understanding how such discrimination, named here as ableism, operates is important and may require studying perspectives of people who do not claim a disability identity.  Ableism may be expressed in a number of ways, and examining how a particular group, in this case siblings of disabled people, understand and value disability may contribute to overall understandings about how ableism works. Thus, the purpose of this study is to explore relationships between siblings of disabled people's broad societal understandings of disability and their attitudes towards it. In order to tease out this relationship further we have also examined factors that impact how people define disability. Using both social psychological and sociological approaches, we have contextualized individual attitudes as providing additional new information about social meanings of disability, and set this study's results against the larger backdrops of debates over meanings of disability within Disability Studies. In our research, participants revealed complex understandings of disability, but most often defined disability as preventing or slowing action, as an atypical function, a lack of independence, and as a socially constructed obstacle. Participants' unconscious (implicit disability attitudes significantly related to their understandings of disability as lacking independence, impairment, and/or in relation to the norm, and their conscious (explicit disability attitudes. Moreover, longer employment in a disability-related industry was correlated with defining disability as a general difference, rather than as slowing or limiting of tasks.

    2017-12-30

    Disability and poverty are interconnected and although this relationship has been recognised, there is a lack of empirical evidence to support any possible causal relationship in this topic, particularly in the context of Latin America (LA). This study tests the hypothesis "Disability increases the risk of multidimensional poverty of people living with disabilities and their families". Using national census data from Brazil, Chile, Colombia, Costa Rica and Mexico, the Global Multidimensional Poverty Index (Global MPI) was calculated with the aim of measuring and comparing the levels of multidimensional poverty of people living in households with and without disabled members in the five countries. We found that in the five countries people with disabilities and their families had higher incidence, intensity and levels of multidimensional poverty compared with people living in other households. Their levels of deprivation were also higher for all the indicators included in the Global MPI and the contribution of this group to the national MPI was higher than their share of the population, thus people with disabilities and their families are overrepresented in those living in multidimensional poverty. People with disabilities and their families are in worse conditions than poor households without disabled members and social policies should aim to reduce their high levels of multidimensional poverty and deprivation.

    The International Summit on Intellectual Disability and Dementia covered a range of issues related to dementia and intellectual disability, including the dearth of personal reflections of persons with intellectual disability affected by dementia. This article reflects on this deficiency and explores some of the personal perspectives gleaned from the literature, from the Summit attendees and from the experiences of persons with intellectual disability recorded or scribed in advance of the two-day Summit meeting. Systemic recommendations included reinforcing the value of the involvement of persons with intellectual disability in (a) research alongside removing barriers to inclusion posed by institutional/ethics review boards, (b) planning groups that establish supports for dementia and (c) peer support. Practice recommendations included (a) valuing personal perspectives in decision-making, (b) enabling peer-to-peer support models, (c) supporting choice in community-dwelling arrangements and (d) broadening availability of materials for persons with intellectual disability that would promote understanding of dementia.

    We introduce the concept of dynamically growing a neural network during training. In particular, an untrainable deep network starts as a trainable shallow network and newly added layers are slowly, organically added during training, thereby increasing the network's depth. This is accomplished by a new layer, which we call DropIn. The DropIn layer starts by passing the output from a previous layer (effectively skipping over the newly added layers), then increasingly including units from the ne...

    that the cost estimates on which they base their calculation vary widely depending on the methodology, jurisdiction, and data used. Because their calculations do not include all costs, notably medical costs covered through health insurance, they represent a lower bound. On that basis, Stabile and Allin argue that many expensive interventions to prevent and reduce childhood disability might well be justified by a cost-benefit calculation.

    Full Text Available Objectives: Reports are indicating of increasing trend of aging and disability in the developing countries while such disabilities are decreasing within the developed countries. This study designed to evaluate the disability and some of its related factors among the elderly population (65 and older in Kashan, Iran. Methods & Materials: A cross-sectional analytical study was conducted on a multi-stage random sample of 350 elderly people (65 year and older in Kashan. The WHO-DAS-II was used as the generic disability measure. The questionnair had 48 questions. The range of score could be between 0-144. Chi-square, t-test analysis and ANOVA were utilized to check significant differences between subgroups. Results: 61% were men and 12% were living lonely. One fourth had some type of addiction, the majority were ilitrate and two thired had not regular phisycal activity.Twenty percent of the old people had a modereate disability and 4.3% were extremely disabled. A significant relationship was found between the disability and variables such as sex, age, living style, needing help, marriage status, living location, addiction, job, level of physical activity, education, and having multiple diseases. Conclusion: In conclusion, geriatric population in Iran, has a lower levels of disability in compare to those of other developed countries. Need of geriatric cares must be be increasing, since the populationpattern of elderly people is increasing in Iran. Female and ilitrate elders were sufering of more disability. These findings indicated the nessesity to more attention to these voulnarable subgroups of population.

    The selective and long-term deposition of iodized oil in the hepatocellular carcinoma (HCC) and its gradual drainage were clinicopathologically analyzed in 13 cases. All patients were Japanese and had an intrahepatic arterial injection of Lipiodol (LIP) mixed with Mitomycin C. The comparison among the follow-up computerized tomography (CT) findings, the observation of the soft x-ray radiogram, and histopathologic studies of the surgical or autopsy materials revealed that the selective deposition of LIP in HCC lasted for a long term, particularly in cases treated by LIP combined with transcatheter arterial embolization (TAE). Also revealed was an extremely gradual decrease of LIP from the HCC. It was thus postulated that, mainly, the accumulated macrophages surrounding LIP around the necrotic cancer tissue and, partially, the intrahepatic lymphatic system itself contributed to this drainage. Further, in histologic sections with lipid staining, x-ray microanalysis proved that the lipid droplets in the cancer tissue included highly concentrated iodine, as a deposition of LIP

    Treatment of leg length inequality via lengthening of the shorter extremity is an infrequent orthopedic procedure due to the requirement of special distraction devices and possible serious complications. Essential qualitative changes in operative technique development are associated with the name of G. A. Ilizarov, who paved the way for the autoregenerate gradual distraction method in the 1950s. In the years 1990 through 2007 a total of 67 patients underwent femur lengthening via gradual distraction using various types of external fixators at the Department of Pediatric Surgery, Orthopedics, and Traumatology, Faculty Hospital in Brno. The quality of bone healing was monitored and a number of parameters followed and statistically evaluated using regularly scheduled X-ray examinations. In 13 cases we had to remove the external fixator following the distraction phase, perform an osteosynthesis via a splint and fill the distraction gap via spongioplasty. The bone healing was satisfactory in the remaining 54 patients and the lengthened bone required no other fixation method. The analysis showed statistically significant deceleration in bone healing following distraction in female patients over 12 years of age, and in boys over 14 years of age. Lack of periosteal callus five weeks after surgery always signified serious problems in further healing. Severe complications were recorded in 11 cases during the distraction phase, and in 12 cases after the removal of the distraction apparatus. Our results fully correspond with the data and experience of others cited authors. In addition our study showed deceleration in bone healing in girls over 12 years and in boys over 14 years of age and serious problem in healing when is lack of periostal callus five weeks after surgery. The aim of this report was to present the results of our study of distraction gap bone healing using the gradual lengthening approach.

    Understanding the disability impact on parenting and caregiving is important for intervention. The present study was designed to understand the differences in perceived disability impact and related coping in mothers having children with intellectual disabilities alone compared to those having children with intellectual disabilities and additional disabilities. Accordingly, 30 mothers of children with intellectual disabilities and 30 mothers of children with intellectual and additional disabilities were assessed for disability impact and coping. Group differences for disability impact were present in specific domains but not overall. Despite variations in coping pattern, both positive and negative coping strategies were observed in both groups. The results may imply that the impact of intellectual disability is so pervasive that except in certain domains mothers may not perceive the further impact of additional disabilities. Positive coping does not rule out negative coping strategies. These findings have specific relevance to service delivery in a cultural context.

  2. Part-time work among older workers with disabilities in Europe.

    2009-05-01

    To analyse the use of part-time work among older workers with disabilities compared with their non-disabled counterparts within a European context. Cross-sectional. Data were drawn from the 2004 Survey of Health, Ageing and Retirement in Europe. The key advantage of this dataset is that it provides a harmonized cross-national dimension, and contains information for European individuals aged 50 years or over on a wide range of health indicators, disability, socio-economic situation, social relations, etc. Older people with disabilities (aged 50-64 years) are more likely to have a part-time job compared with their non-disabled counterparts. Although there is an important employment gap between the two groups, many older workers with disabilities use part-time work to achieve a better balance between their health status and working life. The econometric analysis corroborated that being disabled has a positive effect on the probability of working on a part-time basis, although this effect varies by country. Policy makers must encourage part-time employment as a means of increasing employment opportunities for older workers with disabilities, and support gradual retirement opportunities with flexible and reduced working hours. It is crucial to change attitudes towards older people with disabilities in order to increase their labour participation and reduce their levels of poverty and marginalization.

    to understand the impact of HIV and its comorbidities. The HIV Disability Questionnaire (HDQ) is a self-administered questionnaire developed to describe the presence, severity and episodic nature of disability experienced by people living with HIV. The HDQ is comprised of six domains of disability including: physical symptoms and impairments (20 items); cognitive symptoms and impairments (3 items); mental and emotional health symptoms and impairments (11 items); uncertainty (14 items); difficulties with day-to-day activities (9 items) and challenges to social inclusion (12 items). These domains represent the dimensions of disability measured by the HDQ. The HDQ is the first known HIV-specific disability measure for adults living with HIV. The HDQ may be used by clinicians and researchers to assess disability experienced by adults living with HIV.

    This paper argues against Appel's recent proposal-in this journal-that there is a fundamental human right to sexual pleasure, and that therefore the sexual pleasure of severely disabled people should be publicly funded-by thereby partially legalising prostitution. An alternative is proposed that does not need to pose a new positive human right; does not need public funding; does not need the legalisation of prostitution; and that would offer a better experience to the severely disabled: charitable non-profit organisations whose members would voluntarily and freely provide sexual pleasure to the severely disabled.

    The rate of permanent disability retirement in U.S. Army soldiers and the prevalence of combat-related disabilities have significantly increased over time. Prior research on risk factors associated with disability retirement included soldiers retired prior to conflicts in Iraq and Afghanistan. To identify risk factors for disability discharge among soldiers enlisted in the U.S. Army during military operations in Iraq and Afghanistan. In this case-control study, cases included active duty soldiers evaluated for disability discharge. Controls, randomly selected from soldiers with no history of disability evaluation, were matched to cases based on enlistment year and sex. Conditional logistic regression models calculated odds of disability discharge. Attributable fractions estimated burden of disability for specific pre-existing condition categories. Poisson regression models compared risk of disability discharge related to common disability types by deployment and combat status. Characteristics at military enlistment with increased odds of disability discharge included a pre-existing condition, increased age or body mass index, white race, and being divorced. Musculoskeletal conditions and overweight contributed the largest proportion of disabilities. Deployment was protective against disability discharge or receiving a musculoskeletal-related disability, but significantly increased the risk of disability related to a psychiatric or neurological condition. Soldiers with a pre-existing condition at enlistment, particularly a musculoskeletal condition, had increased odds of disability discharge. Risk of disability was dependent on condition category when stratified by deployment and combat status. Additional research examining conditions during pre-disability hospitalizations could provide insight on specific conditions that commonly lead to disability discharge. Copyright © 2016 Elsevier Inc.

    Graphene pn junction is the brick to build up variety of graphene nano-structures. The analytical formula of the conductance of graphene gradual pn junctions in the whole bipolar region has been absent up to now. In this paper, we analytically calculated that pn conductance with the spin–orbit coupling and stagger potential taken into account. Our analytical expression indicates that the energy gap causes the conductance to drop a constant value with respect to that without gap in a certain parameter region, and manifests that the curve of the conductance versus the stagger potential consists of two Gaussian peaks – one valley contributes one peak. The latter feature allows one to detect the valley polarization without using double-interface resonant devices. - Highlights: • Analytical conductance formula of the gradual graphene pn junction with spin–orbit coupling in the whole bipolar region. • Exploring the valley-dependent transport of gradual graphene pn junctions analytically. • Conductance peak without resonance.

    Robotic surgery was introduced at our institution in 2003, and we used a progressive approach advancing from simple to more complex procedures. A retrospective chart review. Cases included totalled 129. Set-up and operative times have improved over time and with experience. Conversion rates to standard laparoscopic or open techniques were 4.7% and 1.6%, respectively. Intraoperative complications (6.2%), blood loss and hospital stay were directly proportional to complexity. There were no mortalities and the postoperative complication rate (13.2%) was within accepted norms. Our findings suggest that robot technology is presently most useful in cases tailored toward its advantages, i.e. those confined to a single space, those that require performance of complex tasks, and re-do procedures.

    Full Text Available The effects of gradual waterlogging on trees have been little studied. The températe evergreens Nothofagus nítida and N. dombeyi are differentially distributed on soil moisture gradients, only the former being common on poorly-drained sites. We compared the relative height growth rate (RGR H and foliage loss of seedlings subjected experimentally to normal drainage (soil at field capacity, sudden waterlogging and gradual waterlogging for two months to determine which waterlogging regime more accurately predicts interspecific differences in tolerance, as evident from natural distributions. RGR H was similar between species but differed between treatments (normal watering > gradual waterlogging = sudden waterlogging. Sudden waterlogging caused massive foliage loss in the two species, but gradual waterlogging caused much greater foliage loss in N. dombeyi than in N. nítida, indicating some degree of acclimation by the latter species. Linear regressions indicated that RGR H was negatively affected by foliage loss in both species, without differences between them. Since no difference in RGR H was found between species in the waterlogging treatments, but yet in foliage loss, other mechanisms may be in volved in the short term growth reduction of N. nítida. Effects of waterlogging on long-term performance in the field were evaluated by reciprocal transplants between a poorly-drained site naturally occupied by N. nítida, and a well drained site naturally occupied by N. dombeyi. After two growing seasons, N. dombeyi had significantly lower specific leaf área (SLA and RGR H, at the poorly drained site than at its original site. At the poorly drained site N. nítida achieved 100 % survival, compared with 73.5 % in N. dombeyi. Reduced growth and survival of N. dombeyi associated with the negative effects on carbón gain of extensive foliage loss and reduced SLA may thus exelude it from the wetter sites. We conclude that tolerance may be better

    To inform readers of current issues in special education for individuals with intellectual disabilities and summarize recent research and opinion. Two issues dominate special education for students with intellectual disabilities in the early 21st century. First, what should be taught to such students and who should teach them? Second, where should such students be taught - in 'inclusive' settings alongside normal peers or in special settings dedicated to their special needs? Research on teaching reading, arithmetic, and functional daily living skills to students with disabilities suggests the superiority of direct, systematic instruction. Universal design is often seen as supportive of inclusion. Inclusion has been seen as the central issue in special education but is gradually giving way to concern for what students learn. Direct, systematic instruction in reading, arithmetic, and daily living skills is the most effective approach to teaching students with intellectual disabilities. Basic concepts and logic suggest that special and general education cannot be equivalent. We conclude that what students are taught should be put ahead of where they are taught. Our fundamental concern is that students with intellectual disabilities be respected and be taught all they can learn.

  12. Considering the culture of disability in cultural competence education.

    Eddey, Gary E; Robey, Kenneth L

    2005-07-01

    Cultural competence extends beyond understanding those values, beliefs, and needs that are associated with patients' age or gender or with their racial, ethnic, or religious backgrounds. People hold many simultaneous cultural associations, and each have implications for the care process. The "culture of disability" is a pan-ethnic culture for which a set of physician competencies are required to ensure appropriate, culturally sensitive care to persons with congenital or acquired disabilities. Such competencies include communicating with patients who have deficits in verbal communication and avoidance of infantilizing speech; understanding the values and needs of persons with disabilities; the ability to encourage self-advocacy skills of patients and families; acknowledging the core values of disability culture including the emphasis on interdependence rather than independence; and feeling comfortable with patients with complex disabilities. Medical schools have developed programs to increase students' exposure to persons with disabilities and it is suggested that such programs are most effective when they are the result of collaboration with community-based facilities or organizations that serve persons with disabilities in the natural environment. Combining lecture-based instruction and structured experiences with the opportunity for students to interact with patients in their natural environments may facilitate development of competencies with respect to patients with disabilities. The culture of disability should be included as one of the many cultures addressed in cultural competence initiatives in medical school and residency curricula.

    Full Text Available Locating occupational therapy within gendered and racialized systems of power, the authors consider the intersectional nature of critical disability studies discourse and the need for occupational therapy to incorporate such values into practice. This article discusses ways in which occupational therapy as a profession and individual therapists can align with or resist the economic determination which has come to dominate medical systems. It considers some of the political background to the history of the profession and its relationship with power. This positioning of the profession is explored against the impact of neoliberal economic policy on health, rights, service delivery and disability, and against some key issues, the pressure of ageing populations and the positon of occupational therapists as women professionals. Current policies present a critical challenge to central occupational therapy tenets. Occupational therapists may find themselves working both in alliance with disabled people and disability activists, and against them.

  20. Functional disability in elderly with dementia

    Directory of Open Access Journals (Sweden)

    Tainã Alves Fagundes

    2017-03-01

    Full Text Available Introduction: Dementia represents one of the major causes of disability and dependence in old age and can affect functional capacity in all areas of occupational performance, including basic and instrumental activities of daily living (BADL and IADL, respectively, leisure, social participation and others. Objectives: To characterize the functional disability level in elderly people with dementia and verify the existence of correlation between functionality and the stage or type of dementia. Method: Quantitative, exploratory, cross-sectional study, with a sample of 25 caregivers of elderly with dementia. For the characterization of the participants were used structured questionnaires and to assess functional disability, the Disability Assessment Scale for Dementia - DAD was applied. Results: Greater incapacity was observed in the IADL sub item. This finding is compatible with the literature on the hierarchy in functional decline in the elderly: decline begins in IADL, while BADL remain unaffected for a longer period. There was no significant correlation between the type of dementia, age or gender and disability. It was verified through the Spearman coefficient (rho = 0.87, a significant correlation of high magnitude between functional disability and stage of dementia (p = 0.0001. Conclusion: Such findings reiterate the importance of giving priority to early detection and prevention of the functional decline, which is the manifestation of vulnerability among the elderly.

  1. Suicide Attempts Among Adolescents with Self-Reported Disabilities.

    2018-06-01

    This study examines the relative risk for suicide attempts (SA) among high-school students self-identifying with one or more disability classifications (nine); assesses the extent to which youth with disabilities are disproportionately vulnerable to risk factors that predict suicidal behavior among all adolescents; and explores whether disability status adds to risk for SA after accounting for a comprehensive set of known risk and protective factors for SA. Analyses using Wisconsin's 2012 Dane County Youth Assessment Survey data found that youth in each disability category were 3-9 times more likely to report suicide attempt(s) relative to peers, and the endorsement of multiple disabilities tripled the risk SA relative to youth reporting a single disability. Some disability sub-groups, including youth reporting autism spectrum disorder, hearing, and vision impairments reported surprisingly high rates of SA. While youth with disabilities reported disproportionate exposure to adversity in every life domain examined, similar to youth reporting SA, disability status added unique risk for suicidal behavior. This suggests that disability may be a 'fundamental cause' of suicidal behavior, a question that requires further investigation.

    Disability is shown to be both a cause and a consequence of poverty. However, relatively little research has investigated the economic cost of living with a disability. This study reports the results of a study on the extra cost of living with disability in Vietnam in 2011. The study was carried out in eight cities/provinces in Vietnam, including Hanoi and Ho Chi Minh cities (two major metropolitan in Vietnam) and six provinces from each of the six socio-economic regions in Vietnam. Costs are estimated using the standard of living approach whereby the difference in incomes between people with disability and those without disability for a given standard of living serves as a proxy for the cost of living with disability. The extra cost of living with disability in Vietnam accounted for about 8.8-9.5% of annual household income, or valued about US$200-218. Communication difficulty was shown to result in highest additional cost of living with disability and self-care difficulty was shown to lead to the lowest levels of extra of living cost. The extra cost of living with disability increased as people had more severe impairment. Interventions to promote the economic security of livelihood for people with disabilities are needed.

  5. Canadian Disability Policies in a World of Inequalities

    Directory of Open Access Journals (Sweden)

    Deborah Stienstra

    2018-05-01

    Full Text Available Canadian disability-related policies are shaped within a global system of inequalities, including colonialism and neoliberalism. Using a critical theory framework, this article examines the complicated material inequalities experienced by people with disabilities and evident in the intersections of disability, gender, Indigenousness, race, and age. The collectively held ideas that give context to disability policies are at odds. Human rights protections are found in the foundational documents of Canadian society and part of its international commitments, yet these commitments often become window-dressing for a pervasive logic that it is better to be dead than disabled, and medical assistance in dying legislation supports this choice. While human rights protections are essential, they are not sufficient for decolonizing inclusion. Constructive actions between Indigenous peoples and settlers may help to find new ways of addressing disability and inclusion in Canada.

  6. Nurses with disabilities: self-reported experiences as hospital employees.

    Matt, Susan B

    2008-11-01

    Since enactment of the Americans with Disabilities Act of 1990, U.S. employers have been mandated to provide reasonable accommodation for employees with disabilities. Nurses with disabilities have described their experiences, reflecting occurrences that might be noncompliant with these mandates. There is little information available regarding the work experience of nurses with disabilities practicing in hospitals. How these workers view their work world and how they perceive the way others within that environment think of them and their contributions to patient care is important because these individuals must be included as equal participants in a profession that relies on teamwork to function effectively. An exploratory study was conducted to gain a context-based understanding of the lived experiences of hospital-employed nurses with disabilities. Grounded theory methodology was used to uncover themes and to identify factors comprising "disability climate"; such factors might inform the future development of workplace policies supportive of all nurses.

  7. Rehabilitation as a Disability Equality Issue: A Conceptual Shift for Disability Studies?

    Directory of Open Access Journals (Sweden)

    Tom Shakespeare

    2018-03-01

    Full Text Available Rehabilitation is a controversial subject in disability studies, often discussed in terms of oppression, normalisation, and unwanted intrusion. While there may be good reasons for positioning rehabilitation in this way, this has also meant that, as a lived experience, it is under-researched and neglected in disabilities literature, as we show by surveying leading disability studies journals. With some notable exceptions, rehabilitation research has remained the preserve of the rehabilitation sciences, and such studies have rarely included the voices of disabled people themselves, as we also demonstrate by surveying a cross-section of rehabilitation science literature. Next, drawing on new research, we argue for reframing access to rehabilitation as a disability equality issue. Through in-depth discussion of two case studies, we demonstrate that rehabilitation can be a tool for inclusion and for supporting an equal life. Indeed, we contend that rehabilitation merits disability researchers’ sustained engagement, precisely to ensure that a ‘right-based rehabilitation’ policy and practice can be developed, which is not oppressive, but reflects the views and experiences of the disabled people who rehabilitation should serve.

  8. Maltreatment of children with disabilities: the breaking point.

    Murphy, Nancy

    2011-08-01

    The maltreatment of children with disabilities is a serious public health issue. Children with disabilities are 3 to 4 times more likely to be abused or neglected than are their typically developing peers. When maltreated, they are more likely to be seriously injured or harmed. As alarming as these numbers are, they likely underestimate the problem. Children with disabilities encounter all 4 types of abuse: physical, sexual, neglect, and emotional. Here, the author discusses risk factors associated with the maltreatment of children with disabilities, which, as expected, include both child and family factors.

  9. Disability, Procreation, and Justice in the United States

    Kimberly Mutcherson

    2017-11-01

    Full Text Available Parenting and procreation have long been contested legal terrain in the United States as exemplified by a history of abuses against marginalized populations including people with disabilities. While some of the most egregious abuses, such as state sponsored sterilization programs, are relics of the past, it remains true that people with disabilities face distinct and at times insurmountable roadblocks to procreation and parenting. This article details ongoing forms of procreative discrimination against people with disabilities, rejects common justifications for that discrimination, and offers proposals for better protecting the rights to procreate and parent for disabled people.

  10. Trajectories of Work Disability and Economic Insecurity Approaching Retirement.

    Shuey, Kim M; Willson, Andrea E

    2017-07-08

    In this article, we examine the connection between trajectories of work disability and economic precarity in late midlife. We conceptualize work disability as a possible mechanism linking early and later life economic disadvantage. We model trajectories of work disability characterized by timing and stability for a cohort of Baby Boomers (22-32 in 1981) using 32 years of data from the Panel Study of Income Dynamics and latent class analysis. Measures of childhood disadvantage are included as predictors of work disability trajectories, which are subsequently included in logistic regression models predicting four economic outcomes (poverty, asset poverty, home ownership, and pension ownership) at ages 54-64. Childhood disadvantage selected individuals into five distinct classes of work disability that differed in timing and stability. All of the disability trajectories were associated with an increased risk of economic insecurity in late midlife compared to the never work disabled. This study contributes to the aging literature through its incorporation of the early life origins of pathways of disability and their links to economic outcomes approaching retirement. Findings suggest work disability is anchored in early life disadvantage and is associated with economic insecurity later in life. © The Author 2017.

    2017-07-01

    Full Text Available The downfall of the New Order regime in 1998, which was soon followed by the liberalization policy in almost every aspect of politics, opened vast opportunities for the emergence of political expressions including Islamism into the public space. While violent responses indicated by some Islamic groups, who take advantage of the weakening of the state, Tarbiyah Movement (harakah tarbiyah consistently performs gradual Islamization through the system provided by the state. Based on a field research in Jambi, Sumatra, this article discusses the efforts undertaken by the group to incorporate their Islamist ideas into secular education system at the levels of primary and secondary education. This article argues that these all efforts are part of Islamization process of society and the state in Indonesia after the failure of its leaders in doing the same thing at the political level especially in the aftermath of the 1999 general election.

  12. Combat sports for persons with disabilities

    Full Text Available In literature, the term adapted sport indicates sports activities, modified and adapted to persons with disabilities. In spite of their highly prominent values, combat sports are underrepresented among persons with disabilities in Serbia. The benefits of combat sports practicing are numerous, and at some international hospitals, martial sports and arts already have an important role in the treatment of traumatized and disabled persons. Currently, the programme of Paralympic Games includes only two sports, these are fencing and judo, in male and female competition. Almost certainly, karate will also be included in the programme of Paralympic Games, and there are similar ambitions in the case of taekwondo as well. In addition to these sports, some martial arts, especially aikido, thai-chi-chuan and qigong, have obtained significant representation and interest among persons with disabilities. The reasons for weaker interest in other martial sports and arts, should be sought in the fact that they are underrepresented among this population, and that these persons are not offered the possibility of organized practice of such sports. Orientation towards a combat sport brings great refreshment and powerful emotional experience to each practitioner, and this fact has special significance to persons with disabilities. In Serbia, combat sports are not widely represented among persons with disabilities, and only the wrestlers with impaired hearing have achieved significant success on the international stage. On the other hand, the popularity of combat sports among persons with disabilities in the world is significantly growing. It is necessary to take concrete steps to make it so in Serbia as well.

    2017-02-01

    The composition of volcanic gases discharged from Miyakejima volcano has been monitored during the intensive degassing activity that began after the eruption in 2000. During the 15 years from 2000 to 2015, Miyakejima volcano discharged 25.5 Mt of SO2, which required degassing of 3 km3 of basaltic magma. The SO2 emission rate peaked at 50 kt/day at the end of 2000 and quickly decreased to 5 kt/day by 2003. During the early degassing period, the volcanic gas composition was constant with the CO2/SO2 = 0.8 (mol ratio), H2O/SO2 = 35, HCl/SO2 = 0.08, and SO2/H2S = 15. The SO2 emission rate decreased gradually to 0.5 kt/day by 2012, and the gas composition also changed gradually to CO2/SO2 = 1.5, H2O/SO2 = 150, HCl/SO2 = 0.15, and SO2/H2S = 6. The compositional changes are not likely caused by changes in degassing pressure or volatile heterogeneity of a magma chamber but are likely attributed to an increase of hydrothermal scrubbing caused by large decrease of the volcanic gas emission rate, suggesting a supply of gases with constant composition during the 15 years. The intensive degassing was modeled based on degassing of a convecting magma conduit. The gradual SO2 emission rate that decrease without changes in volcanic gas composition is attributed to a reduction of diameter of the convecting magma conduit.

  14. Delayed initiation but not gradual advancement of enteral formula feeding reduces the incidence of necrotizing enterocolitis (NEC in preterm pigs.

    Nada Ghoneim

    Full Text Available Enteral formula feeding is a risk factor for necrotizing enterocolitis (NEC in premature infants, yet studies are conflicting regarding the safest timing for introduction and advancement of feeds. Our aim was to test the effects of early vs. late initiation and abrupt vs. gradual advancement of enteral feeding of an intact vs. hydrolyzed protein formula on NEC incidence and severity in preterm pigs. In Experiment 1, preterm pigs received total parenteral nutrition (TPN at birth with abrupt initiation of enteral formula feeds (50% full intake on d of life (DOL 2 (EA or 5 (LA while PN continued. Pigs were also fed formula containing either intact or hydrolyzed protein. In Experiment 2, preterm pigs received TPN at birth with enteral, hydrolyzed-protein formula feeds introduced on DOL 2 either abruptly (EA; 50% full feeds or gradually (EG; 10-50% full feeds over 5 d while PN continued. NEC incidence and severity were assessed based on macroscopic and histological scoring. In Experiment 1, NEC incidence (41% vs. 70%, P<0.05 and severity were reduced in LA vs. EA groups and LA was associated with a higher survival rate, daily weight gain and jejunum villus height. Piglets fed hydrolyzed vs. intact protein formula had lower stomach content weights and similar NEC incidence. In Experiment 2, NEC incidence and severity were not different between pigs the EG vs. EA group. Proinflammatory gene expression (IL-1β, IL-6 and S100A9 in the ileum was lower in both LA and EG vs. EA groups. In conclusion, delayed initiation but not gradual advancement of enteral feeding is protective against NEC in preterm pigs. Feeding hydrolyzed vs. intact protein formula improved gastric transit without affecting the NEC incidence.

  15. Generalist genes and learning disabilities.

    Plomin, Robert; Kovas, Yulia

    2005-07-01

    The authors reviewed recent quantitative genetic research on learning disabilities that led to the conclusion that genetic diagnoses differ from traditional diagnoses in that the effects of relevant genes are largely general rather than specific. This research suggests that most genes associated with common learning disabilities--language impairment, reading disability, and mathematics disability--are generalists in 3 ways. First, genes that affect common learning disabilities are largely the same genes responsible for normal variation in learning abilities. Second, genes that affect any aspect of a learning disability affect other aspects of the disability. Third, genes that affect one learning disability are also likely to affect other learning disabilities. These quantitative genetic findings have far-reaching implications for molecular genetics and neuroscience as well as psychology. Copyright 2005 APA, all rights reserved.

  16. Hard-magnetic surface layer effect on the erbium orthoferrite plate domain structure in the region of gradual spin reorientation

    Rearrangement of domain structures in the erbium orthoferrite plates with hard-magnetic surface layer is investigated during gradual spin reorientation. This phenomenon is explained by means of the proposed physical models. It is shown that in these plates an approach to the temperature interval of spin reorientation causes a decrease in the density of energy of domain walls separating the internal and surface domains. This decrease results in transition to the domain structure which are close to equilibrium ones inside the crystal. 30 refs.; 4 figs

    Full Text Available In this paper we studied the focusing effect of electromagnetic wave in the two-dimensional graded photonic crystal consisting of Silicon rods in the air background with gradually varying lattice constant. The results showed that graded photonic crystal can focus wide beams on a narrow area at frequencies near the lower edge of the band gap, where equal frequency contours are not concave. For calculation of photonic band structure and equal frequency contours, we have used plane wave expansion method and revised plane wave expansion method, respectively. The calculation of the electric and magnetic fields was performed by finite difference time domain method.

    Disability among older adults is a public health concern. To date there are no in-depth and comprehensive analyses on older adults' disabilities in Bangladesh. This study investigated gender differences in the prevalence of disability and the socio-demographic factors associated with disability among older adults in Bangladesh. This research used a sample of 4176 elderly males and females aged 60 years and over from a nationally representative data set- Bangladesh's 2010 Household Income and Expenditure Survey. The study used both household level and individual level data and applied a wealth index, which was constructed based on household assets using principal component analysis. The Washington Group's short set of questions on disability were used to measure disability. Chi-square tests and ordinal logistic regression models were fit. Forty-two percent of older had some form of functional disability, including 5% of elderly with severe/extreme functional disability. Seven percent of older adults had a self-care disability, including 3% of elderly with a severe/extreme form of self-care disability. Elderly females suffered from all the studied disabilities, including functional and self-care disabilities in higher percentages, and had higher odds ratios of having both functional disability and self-care disability compared to elderly males. The study also identified some significant factors affecting functional disability and self-care disability, namely age, having a chronic condition, wealth status and place of residence, including divisional differences. Programs aimed at reducing functional disability among seniors, particularly elderly females, should be granted the highest priority in Bangladesh.

  10. Disability and the education system.

    Aron, Laudan; Loprest, Pamela

    2012-01-01

    Education is important for all children, but even more so for children with disabilities, whose social and economic opportunities may be limited. In this article, Laudan Aron and Pamela Loprest assess how well the nation's education system is serving students with disabilities. Aron and Loprest trace the evolution of the special education system in the United States from its origins in the civil rights movement of the mid-twentieth century. They note the dual character of federal legislation, which both guarantees eligible children with disabilities the right to a "free, appropriate public education in the least restrictive setting" and establishes a federal funding program to help meet this goal. They then review the types of services and accommodations these children receive from infancy through young adulthood. The special education system has given children with disabilities much greater access to public education, established an infrastructure for educating them, helped with the earlier identification of disabilities, and promoted greater inclusion of these children alongside their nondisabled peers. Despite these advances, many problems remain, including the over- and underidentification of certain subgroups of students, delays in identifying and serving students, and bureaucratic, regulatory, and financial barriers that complicate the program for everyone involved. More important, the authors show that special education students still lag behind their nondisabled peers in educational achievements, are often held to lower expectations, are less likely to take the full academic curriculum in high school, and are more likely to drop out of school. Only limited evidence is available on the effectiveness of specific special education services or on how to improve student achievement for this important subgroup of students. Improving the system will require better ways of understanding and measuring both ends of the special education continuum, namely, what

    To assess the prevalence of disability and service needs in post-earthquake Haiti, and to compare the inclusion and living conditions of people with disabilities to those without disabilities. A population-based prevalence survey of disability was undertaken in 2012 in Port-au-Prince region, which was at the centre of the earthquake in 2010. Sixty clusters of 50 people aged 5 + years were selected with probability proportionate to size sampling and screened for disability (Washington Group short set questionnaire). A case-control study was undertaken, nested within the survey, matching cases to controls by age, gender and cluster. There was additional case finding to identify further children with disabilities. Information was collected on: socioeconomic status, education, livelihood, health, activities, participation and barriers. The prevalence of disability was 4.1% (3.4-4.7%) across 3132 eligible individuals. The earthquake was the second leading cause of disability. Disability was more common with increasing age, but unrelated to poverty. Large gaps existed in access of services for people with disabilities. Adults with disabilities were less likely to be literate or work and more likely to visit health services than adults without disabilities. Children with disabilities were less likely to be currently enrolled at school compared to controls. Children and adults with disabilities reported more activity limitations and participation restriction. Further focus is needed to improve inclusion of people with disabilities in post-earthquake Haiti to ensure that their rights are fulfilled. Almost one in six households in this region of Haiti included a person with a disability, and the earthquake was the second leading cause of disability. Fewer than half of people who reported needing medical rehabilitation had received this service. The leading reported barriers to the uptake of health services included financial constraints (50%) and difficulties with

  12. Disability training in the genetic counseling curricula: bridging the gap between genetic counselors and the disability community.

    Science.gov (United States)

    Sanborn, Erica; Patterson, Annette R

    2014-08-01

    Over the past two decades, disability activists, ethicists, and genetic counselors have examined the moral complexities inherent in prenatal genetic counseling and considered whether and in what ways genetic counseling may negatively affect individuals in the disability community. Many have expressed concerns about defining disability in the context of prenatal decision-making, as the definition presented may influence prenatal choices. In the past few years, publications have begun to explore the responsibility of counselors in presenting a balanced view of disability and have questioned the preparedness of counselors for this duty. Currently, the Accreditation Council for Genetic Counseling (ACGC) only minimally includes disability training in their competencies for genetic counselors, and in their accreditation requirements for training programs. In an attempt to describe current practice, this article details two studies that assess disability training in ABGC-accredited genetic counseling programs. Results from these studies demonstrate that experience with disability is not required by the majority of programs prior to matriculation. Though most program directors agree on the importance of including disability training in the curriculum, there is wide variability in the amount and types of training students receive. Hours dedicated to disability exposure among programs ranged from 10 to 600 hours. Eighty-five percent of program directors surveyed agree that skills for addressing disability should be added to the core competencies. Establishing a set of disability competencies would help to ensure that all graduates have the skills necessary to provide patients with an accurate understanding of disability that facilitates informed decision-making. © 2014 Wiley Periodicals, Inc.

    Over the past 175 years, data related to human disease and death have progressed to a summary measure of population health, the Disability-Adjusted Life Year (DALY). As dairies have intensified there has been no equivalent measure of the impact of disease on the productive life and well-being of animals. The development of a disease-adjusted metric requires a consistent set of disability weights that reflect the relative severity of important diseases. The objective of this study was to use an international survey of dairy authorities to derive disability weights for primary disease categories recorded on dairies. National and international dairy health and management authorities were contacted through professional organizations, dairy industry publications and conferences, and industry contacts. Estimates of minimum, most likely, and maximum disability weights were derived for 12 common dairy cow diseases. Survey participants were asked to estimate the impact of each disease on overall health and milk production. Diseases were classified from 1 (minimal adverse effects) to 10 (death). The data was modelled using BetaPERT distributions to demonstrate the variation in these dynamic disease processes, and to identify the most likely aggregated disability weights for each disease classification. A single disability weight was assigned to each disease using the average of the combined medians for the minimum, most likely, and maximum severity scores. A total of 96 respondents provided estimates of disability weights. The final disability weight values resulted in the following order from least to most severe: retained placenta, diarrhea, ketosis, metritis, mastitis, milk fever, lame (hoof only), calving trauma, left displaced abomasum, pneumonia, musculoskeletal injury (leg, hip, back), and right displaced abomasum. The peaks of the probability density functions indicated that for certain disease states such as retained placenta there was a relatively narrow range of

    Ketamine is often used to manage neuropathic pain in patients with cancer. However, it occasionally causes psychotomimetic effects such as vivid dreams, nightmares, illusions, hallucinations, and altered body image. To examine whether gradual dose titration of ketamine for management of neuropathic pain prevents psychotomimetic effects in patients with advanced cancer. This was a retrospective chart review. We administered ketamine when neuropathic pain in patients with advanced cancer became refractory to opioids and oral adjuvant analgesics. The starting dose of ketamine was 10 mg/d by continuous intravenous infusion. The dose was gradually increased by 10 mg/d every 4 to 6 hours to 50 mg/d or until the pain was relieved.

    Confinement in metabolism pens may provoke a stress response in alpacas that will reduce the welfare of the animal and jeopardize the validity of scientific results obtained in such pens. In this study, we tested a protocol designed to successfully train alpacas to be held in a specially designed metabolism pen so that the animals' confinement would not jeopardize their welfare. We hypothesized that the alpacas would show fewer behaviors associated with a response to stress as training gradually progressed, and that they would adapt to being in the confinement of the metabolism pen. The training protocol was successful at introducing alpacas to the metabolism pens, and it did reduce the incidence of behavioral responses to stress as the training progressed. The success of the training protocol may be attributed to the progressive nature of the training, the tailoring of the protocol to suit alpacas, and the use of positive reinforcement. This study demonstrated that both animal welfare and the validity of the scientific outcomes could be maximized by the gradual training of experimental animals, thereby minimizing the stress imposed on the animals during experimental procedures.

  16. Gradual reforms and the emergence of energy market in China: Evidence from tests for convergence of energy prices

    2009-01-01

    This study investigates the emergence of energy markets by testing for convergence of energy prices with a new dataset on energy spot prices in 35 major cities in China. Both descriptive statistics and unit root are employed to test the convergence of energy prices for each of four fuel price series. The whole study period is divided into two sub-periods in order to reconcile the gradual energy reforms. The results show the steady improvement in energy market performance in China, especially during the second sub-period, which suggests that the market appears to be playing an increasing role in determining energy prices. While panel unit root tests show energy markets are integrated in China as a whole, city-by-city univariate unit root tests suggest that there are still many regional energy markets, probably because energy reserves (especially coal) vary widely across regions. Since China's energy economy is gradually moving towards market-oriented mechanisms, the existing literature may become obsolete soon.

  17. The oriental fruit fly, Bactrocera dorsalis, in China: origin and gradual inland range expansion associated with population growth.

    The oriental fruit fly, Bactrocera dorsalis, expanded throughout mainland China in the last century to become one of the most serious pests in the area, yet information on this process are fragmentary. Three mitochondrial genes (nad1, cytb and nad5) were used to infer the genetic diversity, population structure and demographic history of the oriental fruit fly from its entire distribution range in China. High levels of genetic diversity, as well as a significant correspondence between genetic and geographic distances, suggest that the invasion process might have been gradual, with no associated genetic bottlenecks. Three population groups could be identified, nevertheless the overall genetic structure was weak. The effective number of migrants between populations, estimated using the coalescent method, suggested asymmetric gene flow from the costal region of Guangdong to most inland regions. The demographic analysis indicates the oriental fruit fly underwent a recent population expansion in the Central China. We suggest the species originated in the costal region facing the South China Sea and gradually expanded to colonize mainland China, expanding here to high population numbers.

  1. Madness as disability.

    2014-12-01

    How does society imagine mental illness? Does this shift radically over time and with different social attitudes as well as scientific discoveries about the origins and meanings of mental illness? What happens when we begin to think about mental illness as madness, as a malleable concept constantly shifting its meaning? We thus look at the meanings associated with 'general paralysis of the insane' in the nineteenth century and autism today in regard to disability. In this case study we examine the claims by scholars such as the anthropologist Emily Martin and the psychiatrist Kay Jamison as to the relationship between mental illness, disability and creativity. Today, the health sciences have become concerned with mental illness as a form of disability. How does this change the meaning of madness for practitioners and patients? © The Author(s) 2014.

    This study explores how the ‘care’ of able-bodied employees and managers (observers) affects their relationships with colleagues with cerebral palsy. Disability researchers have established that ‘help’ and ‘care’ may cause feelings of dependency with the recipient. However, few workplace studies...... have investigated the potential negative consequences of ‘caring for’ colleagues with disabilities. Through open-ended interviews conducted in 2013 in 13 Danish work organizations with 13 employees with cerebral palsy and 62 observers, the study examines how the relational aspect of ‘care’ may result...... in relationships between colleagues of ‘parent–child’ or ‘helper–helpless’. The study thus clarifies the inherent contradictions embedded in the dynamics of organizational behaviour in relation to employees with disabilities, namely that workplaces may hire a person with physical limitations (perhaps to deflect...

  3. Readiness of primary school teachers to accept disabled children

    2009-01-01

    Full Text Available The paper presents the results of the research with the basic goal to study the readiness of primary school teachers to accept disabled students. Research participants were 205 teachers from primary schools at the territory of Serbia. The goal was accomplished through: (a studying attitudes towards joint education of disabled students and their peers; (b studying teachers' experiences in working with disabled students; and (c studying teachers' readiness to accept disabled students, depending on their involvement/non-involvement in projects of inclusive education. Teachers express supportive attitudes towards joint schooling, but more than one half of them think that a selective approach is necessary in that process, according to the kind and degree of developmental disability. They support joint schooling from the humanistic point of view, but express concerns about the academic achievement of classes that include disabled students. The majority of teachers had experience in working with disabled students and based on that provided interesting suggestions for improving joint schooling. Higher readiness for accepting disabled students was demonstrated by teachers whose schools were involved in the projects of inclusive education. That implies the need for involving schools in similar projects and enabling teachers' immediate contact with students with developmental disabilities.

    Amad is a wonderful 16-year-old young man from Syria who has recently relocated to the United States from his war-torn native country. In his last few years in Syria, he was primarily at home with his mother, and they sought refuge with a maternal aunt in the United States seeking asylum and treatment of Amad's disability.At 8 years of age, he had intelligence testing in the United Arab Emirates, which showed a verbal intelligence score on the Wechsler intelligence scale for children (WISC) of 68 and a performance of 64. His working memory was 67 and his processing speed was 65. On arrival in the United States, his achievement was roughly at a third-grade level in Arabic. In the year and a half that he has been in the United States, he quickly improved his English skills, which he learned as a toddler. His father remains in Syria unable to safely immigrate and his mother is raising him alone in the United States with the help of her sister.They come to you for an urgent care visit because Amad recently was accused of sexual harassment by two girls at his high school. He is in a substantially separate program but is included for lunch and technology. While in the computer laboratory, he repeatedly approached the girls and asks them to "date" him, and on 1 occasion sat behind 1 girl and repeatedly reached out to stroke her long blonde hair.His mother is distraught because she recently found out that Amad also has a Facebook page and had been attempting to contact the same two girls on social media. The girls' parents recently threatened to file criminal harassment charges and Amad's mother comes to you asking for help with making Amad stop this activity. What would you do next?

    Martin-Fumadó, Carles; Martí Amengual, Gabriel; Puig Bausili, Lluïsa; Arimany-Manso, Josep

    2014-03-01

    Temporary disability is the condition that workers face when, as the result of illness (common or professional) or accident (work-related or not), they are temporarily prevented from performing their work and require health care. The management of temporary disability is a medical act that involves (in addition to a complex clinical assessment) obvious social, occupational and financial connotations and requires continuing medical follow-up from doctors, as well as responses to medical-legal conflicts. The regulatory framework on the subject is extensive in the Spanish setting and highly diverse in the European setting. Beyond the regulatory framework, the repercussions of temporary disability are self-evident at all levels. Although determining temporary disability is a common medical act for practicing physicians, it is not exempt from risks or difficulties arising from the assessment itself and the characteristics of practicing medical care. Established medical-legal conflicts include the processing of health data and the requirements for transferring information related to workers' temporary disability to their company's medical services. The interest and usefulness demonstrated by the data obtained from forensic medicine for public health require the incorporation of these data into general healthcare information, as it could be essential to the surveillance of worker health. The recommendations established by medical societies, as good practice guidelines, are especially useful in this type of conflict. Copyright © 2014 Elsevier España, S.L. All rights reserved.

Material and Method:The study retrospectively assessed 3112 patients admitted to the disability ward, of which 601 geriatric patients were included in the study. Results: Of the 601 patients, 53.1% were men and 46.9% were women. The mean age of these patients was 60 (std ± 18.35 years. Some of the reasons for admission in the hospital were need for social services (45.6% and determination of disability rate (21.6%. Most common diseases in patients aged %u226565 years were hypertension (21.6%, diabetes (12.6%, and chronic obstructive lung disease and dilated cardiomyopathy (3.7%; p 0.05. Internal disability rate was not statistically significant (p > 0.05, but total disability was statistically significant (p < 0.05. Moreover, prevalence of additional conditions was statistically significant (p < 0.05 in patients aged %u226565 years.Discussion: Rapid increases in life expectancy and number of older people has increased the prevalence of disabilities among older people. Being diagnosed with chronic diseases should not be the end of life for geriatric populations. Their mood, social life, general health, and mental profile should progress. Sufficient attention should be paid to the special needs of older patients thereby leading to a wider use of facilities.

  14. Gradual Increase of FcγRIIIa/CD16a Expression and Shift toward IFN-γ Secretion during Differentiation of CD56dim Natural Killer Cells

    Directory of Open Access Journals (Sweden)

    Laurie Lajoie

    2017-11-01

    Full Text Available Natural killer (NK cell effector functions include cytotoxicity and secretion of cytokines such as interferon-γ (IFN-γ. The immature CD56bright subset of human NK cells lacks expression of FcγRIIIa/CD16a, one of the low-affinity immunoglobulin G receptors, or exhibits low-density expression (CD56brightCD16−/dim and produces IFN-γ in response to cytokine stimulation, whereas the mature CD56dimCD16+ subset is the most cytotoxic one. A further differentiation/maturation of the latter subset according to the gradual loss of NKG2A and/or gain of KIR2DL (CD158a and CD158b has been demonstrated and the ability to produce IFN-γ in response to activating receptor (AR co-engagement is gradually acquired during terminal differentiation. In the course of flow cytometry analysis of CD56dim NK cells, we noted a substantial intraindividual heterogeneity of expression of FcγRIIIa. FcγRIIIa is unique among ARs: it does not require the co-engagement of other ARs to induce substantial cytotoxicity or cytokine synthesis in CD56dim cells. We, therefore, investigated whether individual differentiation/maturation of polyclonal CD56dim NK cells defined by expression of NKG2A/KIR2DL is related to FcγRIIIa expression and to the heterogeneity of NK cell responses upon FcγRIIIa engagement. When we analyzed unstimulated CD56dim cells by increasing level of FcγRIIIa expression, we found that the proportion of the more differentiated CD158a,h+ and/or CD158b,j+ cells and that of the less differentiated NKG2A+ cells gradually increased and decreased, respectively. FcγRIIIa engagement by using plate-bound murine anti-CD16 monoclonal antibody (mAb or rituximab or trastuzumab (two therapeutic mAbs, resulted in donor-dependent partial segregation of IFN-γ-producing and/or degranulating CD56dim cells. Importantly, the proportion of CD158a,h/b,j+ cells and that of NKG2A+ cells was increased and decreased, respectively, IFN-γ-producing cells, whereas these proportions

  15. Living with disability. Taking care of siblings

    Directory of Open Access Journals (Sweden)

    Roberta Caldin

    2016-11-01

    Full Text Available The birth of a disabled child is a critical event that places all the members of the family in a condition of great vulnerability. When talking about families with a disabled child, attention is usually focused on the parents. Siblings tend to play a marginal role, as shown in the referred literature, in this specific field of investigation. Communicating diagnosis to siblings means involving them in the process of family change, making them active players rather than “spectators” in their own “existential niche”. Communication of diagnosis is a delicate, continuous process that has to be tackled appropriately, using targeted words and educational actions. Children need help in accepting and welcoming their disabled sibling, with all his/her characteristics (and deficits, through a balanced, pondered approach that includes both the dimension of co-development and the acknowledgement of problematic situations.

    Many decisions are made under suboptimal circumstances, such as time constraints. We examined how different experiences of time constraints affected decision strategies on a probabilistic inference task and whether individual differences in working memory accounted for complex strategy use across different levels of time. To examine information search and attentional processing, we used an interactive eye-tracking paradigm where task information was occluded and only revealed by an eye fixation to a given cell. Our results indicate that although participants change search strategies during the most restricted times, the occurrence of the shift in strategies depends both on how the constraints are applied as well as individual differences in working memory. This suggests that, in situations that require making decisions under time constraints, one can influence performance by being sensitive to working memory and, potentially, by acclimating people to the task time gradually.

    The purpose of this study was to evaluate the deflection forces of Nitinol orthodontic wires placed in different types of brackets: metallic, reinforced polycarbonate with metallic slots, sapphire, passive and active self-ligating, by assessing strength values variation according to gradual increase in wire diameter and deflection and comparing different combinations in the different deflections. Specimens were set in a clinical simulation model and evaluated in a Universal Testing Machine (INSTRON 3342), using the ISO 15841 protocol. Data were subjected to One-way ANOVA, followed by Tukey tests (pbrackets presented the most similar behavior to each other. For conventional brackets there was no consistent behavior for any of the deflections studied. Self-ligating brackets presented the most consistent and predictable results while conventional brackets, as esthetic brackets, showed very different patterns of forces. Self-ligating brackets showed higher strength in all deflections when compared with the others, in 0.020-inch wires.

    Ds relacionan el prestigio de la empresa a una concepción de discapacidad que no las coloca como un desviante de un estándar normal de ser humano. Además, fue posible identificar aspectos considerados importantes en el proceso de inserción de PcDs, como el reconocimiento de la inclusión como valor organizacional, la necesidad de adecuación de las condiciones de trabajo, el papel de las PcDs en el proceso de inclusión y la importancia de la convivencia con PcDs en un escenario favorable a su desempeño.The aim of this article was to verify in the point of view of people with disabilities (PWDs who are working in the labor market if there was any relation between their organizational values perceptions and the ways that they saw the disability in the workplace. The research took place in a company that is reference in inclusion in Brazil. Two questionnaires were used: the Inventory of Disability Conceptions in Work Situations and the Inventory of Organizational Values. Semi-structured interviews with PWDs, their managers and the coordinators of the inclusion program and interviews with PWDs, their managers and coordinators of the inclusion program were carried out. It was verified a negative correlation between the PWDs perception about prestige and the form as normality is seen by the company, that means that the PWDs connect the prestige of the company to a conception of deficiency that does not place them differently of a normal standard of human being. Moreover, it was possible to identify aspects considered important in the process of insertion of PWDs as the recognition of the inclusion as organizational value, the necessity of adequacy to the work conditions, the role of the PWDs in the inclusion process and the importance of the relationship with PWDs in a scene favorable to their performance.

    Full Text Available Introduction. Physical activity is critical to effective rehabilitation in people with disabilities and, consequently, is of high importance in their lives. However, participation of the disabled in physical activity, including tourism, is a much more complex issue than in the case in able-bodied individuals. Material and methods. This paper aims to fill the gap and familiarise the reader with barriers faced by the disabled who engage in tourism. The study group consisted of randomly selected 460 participants with certificates specifying the degree of their disability. The group included 55 (12% individuals with visual impairments, 203 (44.1% individuals with hearing impairments, and 202 (43.9% individuals with locomotor system disabilities. Results. The data derived from interviews made with people with physical dysfunctions, designed with a view to achieving the aims of the study, were used to develop logistic regression models. Conclusions. On average, the greatest and smallest numbers of barriers were reported by individuals with severe disabilities and those who had large families, respectively. Younger disabled people most often complained about the equipment barriers to participation in tourism. Older respondents were mostly challenged with social barriers. Of all the determinants analysed in the study, the perception of barriers to participation in tourism most often depended on the subjects’ degree of disability.

  3. Harmonic hopping, and both punctuated and gradual evolution of acoustic characters in Selasphorus hummingbird tail-feathers.

    Directory of Open Access Journals (Sweden)

    Christopher James Clark

    Full Text Available Models of character evolution often assume a single mode of evolutionary change, such as continuous, or discrete. Here I provide an example in which a character exhibits both types of change. Hummingbirds in the genus Selasphorus produce sound with fluttering tail-feathers during courtship. The ancestral character state within Selasphorus is production of sound with an inner tail-feather, R2, in which the sound usually evolves gradually. Calliope and Allen's Hummingbirds have evolved autapomorphic acoustic mechanisms that involve feather-feather interactions. I develop a source-filter model of these interactions. The 'source' comprises feather(s that are both necessary and sufficient for sound production, and are aerodynamically coupled to neighboring feathers, which act as filters. Filters are unnecessary or insufficient for sound production, but may evolve to become sources. Allen's Hummingbird has evolved to produce sound with two sources, one with feather R3, another frequency-modulated sound with R4, and their interaction frequencies. Allen's R2 retains the ancestral character state, a ∼1 kHz "ghost" fundamental frequency masked by R3, which is revealed when R3 is experimentally removed. In the ancestor to Allen's Hummingbird, the dominant frequency has 'hopped' to the second harmonic without passing through intermediate frequencies. This demonstrates that although the fundamental frequency of a communication sound may usually evolve gradually, occasional jumps from one character state to another can occur in a discrete fashion. Accordingly, mapping acoustic characters on a phylogeny may produce misleading results if the physical mechanism of production is not known.

    Salinity can affect the performance of biological wastewater treatment in terms of nutrient removal. The effect of salt on aerobic granular sludge (AGS) process in terms of granulation and nutrient removal was examined in this study. Experiments were conducted to evaluate the effect of salt (15 g/L NaCl) on granule formation and nutrient removal in AGS system started with flocculent sludge and operated at DO of 2.5 mg/L (phase I). In addition, experiments were conducted to evaluate the effect of gradually increasing the salt concentration (2.5 g/L to 15 g/L NaCl) or increasing the DO level (2.5 mg/L to 8 mg/L) on nutrient removal in AGS system started with granular sludge (phase II) taken from an AGS reactor performing well in terms of N and P removal. Although the addition of salt in phase I did not affect the granulation process, it significantly affected nutrient removal due to inhibition of ammonia oxidizing bacteria (AOB) and phosphate accumulating organisms (PAOs). Increasing the DO to 8 mg/L or adapting granules by gradually increasing the salt concentration minimized the adverse effect of salt on nitrification (phase II). However, these strategies were not successful for mitigating the effect of salt on biological phosphorus removal. No nitrite accumulation occurred in all the reactors suggesting that inhibition of biological phosphorus removal was not due to the accumulation of nitrite as previously reported. Also, glycogen accumulating organisms were shown to be more tolerant to salt than PAO II, which was the dominant PAO clade detected in this study. Future studies comparing the salinity tolerance of different PAO clades are needed to further elucidate the effect of salt on PAOs.

    Physical therapists should implement practice conditions that promote motor skill learning after neurological injury. Errorful and errorless practice conditions are effective for different populations and tasks. Errorful learning provides opportunities for learners to make task-relevant choices. Enhancing learner autonomy through choice opportunities is a key component of the Optimizing Performance through Intrinsic Motivation and Attention for Learning (OPTIMAL) theory of motor learning. The objective of this study was to evaluate the interaction between error opportunity frequency and OPTIMAL (autonomy-supportive) practice conditions during stepping sequence acquisition in a virtual environment. Forty healthy young adults were randomized to autonomy-supportive or autonomy-controlling practice conditions, which differed in instructional language, focus of attention (external vs internal) and positive versus negative nature of verbal and visual feedback. All participants practiced 40 trials of 4, six-step stepping sequences in a random order. Each of the 4 sequences offered different amounts of choice opportunities about the next step via visual cue presentation (4 choices; 1 choice; gradually increasing [1-2-3-4] choices, and gradually decreasing [4-3-2-1] choices). Motivation and engagement were measured by the Intrinsic Motivation Inventory (IMI) and the User Engagement Scale (UES). Participants returned 1-3 days later for retention tests, where learning was measured by time to complete each sequence. No choice cues were offered on retention. Participants in the autonomy-supportive group outperformed the autonomy-controlling group at retention on all sequences (mean difference 2.88s, p errorful (4 choice) sequence (p error opportunities over time, suggest that participants relied on implicit learning strategies for this full body task and that feedback about successes minimized errors and reduced their potential information-processing benefits.

    The definition of disability had been unclear until the International Classification of Functioning, Disability, and Health was promulgated in 2001 by the World Health Organization (WHO). Disability is a critical but relatively neglected public-health concern. We conducted this study to measure disabilities by using the WHO Disability Assessment Schedule 2.0 (WHODAS 2.0) and identify the factors that contribute to disabilities. We obtained and analyzed the data on people who applied to Taiwan's disability registration system between September 2012 and August 2013. A total of 158,174 cases were selected for this study. Among the people included in this study, 53% were male, and the females were on average 3 years older than the males. More males than females were of a low socioeconomic status, but the rate of employment was higher among the males than among the females. Age, sex, place of residence, and types and severity of impairment were all determined to be factors that independently contributed to disability. This study has demonstrated that disability can be measured and compared using WHODAS 2.0. Increasing the public-health attention devoted to disability and identifying the factors associated with disability can promote independence and social participation in people with disabilities.

    To our knowledge, no study has determined whether smoking prevalence is higher among people with disabilities than among people without disabilities across all U.S. states. Neither do we know whether people with disabilities and people without disabilities receive the same quality of advice about tobacco-cessation treatment from medical providers. We analyzed data from the 2004 Behavioral Risk Factor Surveillance System to estimate differences between people with and people without disabilities in smoking prevalence and the receipt of tobacco-cessation treatment advice from medical providers. We found that smoking prevalence for people with disabilities was approximately 50% higher than for people without disabilities. Smokers with disabilities were more likely than smokers without disabilities to have visited a medical provider at least once in the previous 12 months and to have received medical advice to quit. More than 40% of smokers with disabilities who were advised to quit, however, reported not being told about the types of tobacco-cessation treatment available. Ensuring that people with disabilities are included in state-based smoking cessation programs gives states an opportunity to eliminate health disparities and to improve the health and wellness of this group. Ways to reduce unmet preventive health care needs of people with disabilities include provider adoption of the Public Health Service's clinical practice guideline for treating tobacco use and dependence and the provision of smoking cessation services that include counseling and effective pharmaceutical treatment.

    Research suggests that the uptake of cervical screening by women with intellectual disabilities (commonly known as learning disabilities within UK policy frameworks, practice areas and health services) is poor compared to women without intellectual disabilities. The present study explored learning disability nurses' experiences of supporting women with intellectual disabilities to access cervical screening in order to examine their role in promoting attendance and elucidate potential barriers and facilitators to uptake. Ten participants recruited from a specialist learning disability service completed a semi-structured interview and data were analysed using experiential thematic analysis. Identified individual barriers included limited health literacy, negative attitudes and beliefs and competing demands; barriers attributed to primary care professionals included time pressures, limited exposure to people with intellectual disabilities and lack of appropriate knowledge, attitudes and skills. Attendance at cervical screening was facilitated by prolonged preparation work undertaken by learning disability nurses, helpful clinical behaviours in the primary care context and effective joint working. © The Author(s) 2014.

  17. Exploration of the academic lives of students with disabilities at South African universities: Lecturers’ perspectives

    Methods: In an effort to understand the lives of students with disabilities better, a study which included students with disabilities, lecturers and disability supporting staff was conducted at two South African universities – University of the Free State and University of Venda. The paper takes a snapshot view of four lecturers and their perceptions of the lives of students with disabilities at their respective universities. Results and Conclusion: Although most disability literature report students with disabilities blaming lecturers for their failure to advance their needs, this paper highlights that the education system needs to be supportive to lecturers for the inclusive agenda to be realised. An argument is made for a more comprehensive approach towards a national disability policy in higher education involving many stakeholders. Without a broader understanding of disability, it will be difficult to engage with the complex ways in which inequalities emerge and are sustained.

    Although some studies have analysed the disability phenomenon and its effect on, for example, labour force participation, wages, job satisfaction, or the use of disability pension, the empirical evidence on how disability steals time (e.g. hours of work) from individuals is very scarce. This article examines how disabled individuals allocate their time to daily activities as compared to their non-disabled counterparts. Using time diary information from the Spanish Time Use Survey (last quarter of 2002 and the first three quarters of 2003), we estimate the determinants of time (minutes per day) spent on four aggregate categories (market work, household production, tertiary activities and leisure) for a sample of 27,687 non-disabled and 5250 disabled individuals and decompose the observed time differential by using the Oaxaca-Blinder methodology. The results show that disabled individuals devote less time to market work (especially females), and more time to household production (e.g. cooking, cleaning, child care), tertiary activities (e.g., sleeping, personal care, medical treatment) and leisure activities. We also find a significant effect of age on the time spent on daily activities and important differences by gender and disability status. The results are consistent with the hypothesis that disability steals time, and reiterate the fact that more public policies are needed to balance working life and health concerns among disabled individuals.

    Full Text Available We welcome Andrew Haig's critique of our paper, "Disability & Health: A research agenda" in Social Inclusion. Our paper sought to identify research priorities to better understand, provide enhanced services and a better quality of life for people with disabilities, particularly in relation to their health and wellbeing. Haig's critique makes several important points that deserve serious consideration. His comments reflect a view of the relationship between disability and health which is different from the one we have espoused. Specifically, Haig argues that (a disability is a health problem, (b medical rehabilitation should be separated from Community Based Rehabilitation (CBR, and (c the evidence base for medical rehabilitation is much stronger than for CBR. We address each of these points below arguing that while some types of disability clearly result from health problems; often disability is not experienced as a health problem; and sometimes, disability in interaction with restricted access is the cause of health problems.

    All 50 states and the District of Columbia have statutes outlining the grounds for terminating parental rights (TPR) in relation to child abuse and neglect. Although recent research has found that parents with disabilities are not more likely to maltreat their children than parents without disabilities (Glaun & Brown, 1999; Oyserman, Mowbray, Meares, & Firminger, 2000), studies have found very high rates of TPR of parents with disabilities (Accardo & Whitman, 1989). The objective of this study is to examine how states are including disability in their TPR statutes. This study used legal document analysis, consisting of a comprehensive Boolean search of the state codes of the 50 states and District of Columbia (DC) relating to TPR, using the most recent state code available on Lexis-Nexis in August 2005. TPR and related statutes were searched for contemporary and historical disability related terms and their common cognates, such as: "mental," "disability," "handicap," and "incapacity." Two researchers independently conducted the searches, and the searches were reconciled. A code list was then developed to measure for inclusion of disability, preciseness, scope, use of language, and references to accessibility or fairness. Statutes were then reanalyzed, and groupings developed. Thirty-seven states included disability-related grounds for termination of parental rights, while 14 states did not include disability language as grounds for termination. Many of these state codes used outdated terminology, imprecise definitions, and emphasized disability status rather than behavior. All of the 14 states that do not include disability in TPR grounds allowed for termination based on neglectful parental behavior that may be influenced by a disability. The use of disability language in TPR statutes can put an undue focus on the condition of having a disability, rather than parenting behavior. This paper recommends that states consider removing disability language from their

    Full Text Available Disability employment is a major tool for creating inclusive society. In Russia, the main obstacles to employment of the disabled are imperfect statutory measures aimed at improving competitiveness of this population group in the labor market; low prestige of jobs for people with disabilities; the employers’ unwillingness to hire disabled people. The purpose of this study is to determine the barriers disabled people face on the labor market and to justify the expedience of investing public funds in activities aimed at promoting disabled employment. Works of Russian and foreign authors, national statistics, results of sociological surveys of the population and people with disabilities conducted on the territory of the Vologda Oblast in 2013–2015 represent the information base of the study. The article reviews the impact of employment quotas for the disabled; in particular, it has been established that the number of the employed under such quotas during the period from 2008 to 2014 has declined. Based on the results of domestic research the authors have determined the reasons underlying lack of effectiveness of this social policy tool. One of the problems of promoting disability employment is training and re-training of the disabled. According to official statistics, only 38% of the employed disabled who live in a city are employed in the area of their specialty. At the same time, the results of research h of Russian authors show that training of an expert (even with consideration of their health capacities pays off within 4 years. Using the example of the Vologda Oblast, the authors show that annual tax revenues in employment of the disabled to jobs with wages close to the regional average may reach 33 million rubles. They also estimate the approximate regional cost of workplace equipment for the disabled. Finally, the authors propose a list of key courses of action on increasing competitiveness of the disabled in the labor market

Using data taken from the German Socio-Economic Panel for the period 2008-2013, we estimate life satisfaction equations for males and females (running a fixed-effects model) which include a set of variables measuring the number of sleep hours on workdays and weekends. A higher number of sleep hours on workdays increase life satisfaction for all males and females. However, the contribution of each hour of sleep on workdays is greater for males with disabilities in terms of life satisfaction, whereas for females no significant differences by disability status have been found. Although sleep hours on weekends also increase life satisfaction, the magnitude of the coefficients is relatively higher than that found for the corresponding hours of sleep on workdays, but only for the male sample (disabled or not). The participation and commitment of policymakers, governments, trade unions, employers, and health care professionals are key aspects for developing and formulating new guidelines and specific measures that promote a healthy lifestyle and increase sleep duration. Such guidelines and measures are of essence for people with disabilities who are employed (e.g. using brief sleep opportunities during prolonged work periods, which can contribute to reducing fatigue, stress and anxiety).

    The purpose of this systematic review was to synthesize existing empirical research on disability identity development. This review is organized to present the demographics of participants and types of disabilities represented in the existing data, measures of disability identity development and theoretical models of disability identity development. Electronic databases (EBSCO, PsycINFO, ERIC, and Sociological Abstracts) were searched for all peer reviewed empirical studies published between 1980 and 2017. Articles were excluded if they were theoretical and/or did not include participants with disabilities, or focused on a disability-specific community identity rather than general disability identity. Empirical articles (N = 41) were included in the final review. An overwhelming majority (75.6%) were qualitative in nature, with only 22% of the articles reviewed being quantitative and only 1 that utilized a mixed methods design. The results suggest that disability identity can be considered a unique phenomenon that shapes persons' ways of seeing themselves, their bodies, and their way of interacting with the world. Disability identity development has the potential to become an important factor in developing effective interventions and/or therapies. Identity development is a fundamentally social process, and identities are formed through mirroring, modeling, and recognition through available identity resources, and so it is imperative that able-bodied professionals (i.e., rehabilitation professionals, therapists, teachers and caregivers) working with individuals with disabilities become aware of this developmental process to be able to better support individuals along this journey.

    To identify the characteristics of peer-reviewed literature on citizenship and disability published in English from 1985 to 2015. A scoping review was conducted using the Arksey and O'Malley framework. Several databases were searched for peer-reviewed journal articles including the terms citizenship and disability, impairment or handicap in their abstract or title; published between 1985 and 2015; in English. A total of 295 articles were included. Key findings are (1) the number of articles about disability and citizenship increased dramatically over the past three decades, (2) the meaning of citizenship is often left undiscussed, (3) citizenship is more often discussed in terms of access to social rights and less so in regards to contributions to society and participation in family life, technology and culture, (4) disabled people tend to be represented as a homogeneous category, (5) most studies are qualitative and non-participatory. To broaden knowledge about the situation, membership and participation of persons with disabilities in society, further research should develop the conceptual use of citizenship in relation to disability, explore different research designs, investigate various citizenship sectors and take into account the complexity of personal and social situations of persons with disabilities. Implications for Rehabilitation The notion of citizenship is closely related to the goals of rehabilitation as it touches upon issues of membership and participation in society; Understanding the multiple dimensions of citizenship will help practitioners to design and improve rehabilitation treatments and connect these not only to social citizenship rights but also to the various social roles and contributions of persons with disabilities; A better understanding of the complex relationship between citizenship and disability on the part of practitioners is crucial since strategies and policy documents about persons with disabilities often mention citizenship.

  8. Gradual crossover in molecular organization of stable liquid H2O at moderately high pressure and temperature

    Full Text Available Using the literature raw data of the speed of sound and the specific volume, the isothermal compressibility, κT, a second derivative thermodynamic quantity of G, was evaluated for liquid H2O in the pressure range up to 350 MPa and the temperature to 50 ºC. We then obtained its pressure derivative, dκT/dp, a third derivative numerically without using a fitting function to the κT data. On taking yet another p-derivative at a fixed T graphically without resorting to any fitting function, the resulting d2κT/dp2, a fourth derivative, showed a weak but clear step anomaly, with the onset of the step named point X and its end point Y. In analogy with another third and fourth derivative pair in binary aqueous solutions of glycerol, dαp/dxGly and d2αp/dxGly2, at 0.1 MPa (αp is the thermal expansivity and xGly the mole fraction of solute glycerol in our recent publication [J. Solution Chem. 43, 663-674 (2014; DOI:10.1007/s10953-013-0122-7], we argue that there is a gradual crossover in the molecular organization of pure H2O from a low to a high p-regions starting at point X and ending at Y at a fixed T. The crossover takes place gradually spanning for about 100 MPa at a fixed temperature. The extrapolated temperature to zero p seems to be about 70 – 80 °C for points X and 90 – 110 °C for Y. Furthermore, the mid-points of X and Y seem to extrapolate to the triple point of liquid, ice Ih and ice III. Recalling that the zero xGly extrapolation of point X and Y for binary aqueous glycerol at 0.1 MPa gives about the same T values respectively, we suggest that at zero pressure the region below about 70 °C the hydrogen bond network is bond-percolated, while above about 90 ºC there is no hydrogen bond network. Implication of these findings is discussed.

  9. Management of disabilities associated with achondroplasia.

    Achondroplasia is a skeletal dysplasia that manifests as short stature. Impairment and complications range over many disciplines including orthopedics, pediatrics, neurology, and otolaryngology. The major impairments of the extremities are short limbs, limited elbow and hip extension, and knee and leg deformities that can cause disabilities in arm function and locomotion. Hydrocephalus, a narrow foramen magnum, spinal deformity, and spinal canal stenosis can cause neurological problems, leading to disabilities in locomotion, communication, and learning. Malfunctions of the otolaryngeal system such as otitis media, upper respiratory obstruction, deafness, speech delay, and malocclusion are interrelated and can also lead to disabilities in communication and learning. Although such disabilities may cause social handicaps, most children receive a normal education. Their social maturity scale is comparable to that of normal children, but their scale of locomotion is not. The reported occupational level of female adult patients is lower than that of their unaffected siblings. When managing patients, orthopedists should consider the overall aspects of achondroplasia, including natural development and complications other than orthopedic factors.

  10. Common visual problems in children with disability.

    Salt, Alison; Sargent, Jenefer

    2014-12-01

    Children with disability are at a substantially higher risk of visual impairment (VI) (10.5% compared with 0.16%) but also of ocular disorders of all types, including refractive errors and strabismus. The aetiology of VI in children with disability reflects that of the general population and includes cerebral VI, optic atrophy, as well as primary visual disorders such as retinal dystrophies and structural eye anomalies. VI and other potentially correctable ocular disorders may not be recognised without careful assessment and are frequently unidentified in children with complex needs. Although assessment may be more challenging than in other children, identifying these potential additional barriers to learning and development may be critical. There is a need to develop clearer guidelines, referral pathways and closer working between all professionals involved in the care of children with disability and visual disorders to improve our focus on the assessment of vision and outcomes for children with disability.

    Children with disabilities are thought to have an increased risk of unintentional injuries, but quantitative syntheses of findings from previous studies have not been done. We conducted a systematic review and meta-analysis to assess whether pre-existing disability can increase the risk of unintentional injuries among children when they are compared to children without disability. We searched 13 electronic databases to identify original research published between 1 January 1990 and 28 February 2013. We included those studies that reported on unintentional injuries among children with pre-existing disabilities compared with children without disabilities. We conducted quality assessments and then calculated pooled odds ratios of injury using random-effects models. Fifteen eligible studies were included from 24,898 references initially identified, and there was a total sample of 83,286 children with disabilities drawn from the eligible studies. When compared with children without disabilities, the pooled OR of injury was 1.86 (95 % CI 1.65-2.10) in children with disabilities. The pooled ORs of injury were 1.28, 1.75, and 1.86 in the 0-4 years, 5-9 years, and ≥10 years of age subgroups, respectively. Compared with children without disabilities, the pooled OR was 1.75 (95 % CI 1.26-2.43) among those with International Classification of Functioning (ICF) limitations. When disability was defined as physical disabilities, the pooled OR was 2.39 (95 % CI 1.43-4.00), and among those with cognitive disabilities, the pooled OR was 1.77 (95 % CI 1.49-2.11). There was significant heterogeneity in the included studies. Compared with peers without disabilities, children with disabilities are at a significantly higher risk of injury. Teens with disabilities may be an important subgroup for future injury prevention efforts. More data are needed from low- and middle-income countries.

  16. Unpacking intoxication, racialising disability.

    Science.gov (United States)

    Chen, Mel Y

    2015-06-01

    This article examines concepts whose strictly medical applications have only partly informed their widespread use and suggests that demonstrably shared logics motivate our thinking across domains in the interest of a politically just engagement. It considers exchanges between the culturally complex concepts of 'toxicity' and 'intoxication', assessing the racialised conditions of their animation in several geopolitically--and quite radically--distinct scenarios. First, the article sets the framework through considering the racial implications of impairment and disability language of 'non-toxic' finance capital in the contemporary US financial crisis. Shifting material foci from 'illiquid financial bodies' to opiates while insisting that neither is 'more' metaphorically toxic than the other, the article turns to address the role of opium and temporality in the interanimations of race and disability in two sites of 19th-century British empire: Langdon Down's clinic for idiocy, and China's retort on opium to Queen Victoria. The article concludes with a provocation that suggests yet another crossing of borders, that between researcher and researched: 'intoxicated method' is a hypothetical mode of approach that refuses idealised research positions by 'critically disabling' the idealised cognitive and conceptual lens of analysis.

  17. Formation of Large-scale Coronal Loops Interconnecting Two Active Regions through Gradual Magnetic Reconnection and an Associated Heating Process

    Coronal loops interconnecting two active regions (ARs), called interconnecting loops (ILs), are prominent large-scale structures in the solar atmosphere. They carry a significant amount of magnetic flux and therefore are considered to be an important element of the solar dynamo process. Earlier observations showed that eruptions of ILs are an important source of CMEs. It is generally believed that ILs are formed through magnetic reconnection in the high corona (>150″–200″), and several scenarios have been proposed to explain their brightening in soft X-rays (SXRs). However, the detailed IL formation process has not been fully explored, and the associated energy release in the corona still remains unresolved. Here, we report the complete formation process of a set of ILs connecting two nearby ARs, with successive observations by STEREO-A on the far side of the Sun and by SDO and Hinode on the Earth side. We conclude that ILs are formed by gradual reconnection high in the corona, in line with earlier postulations. In addition, we show evidence that ILs brighten in SXRs and EUVs through heating at or close to the reconnection site in the corona (i.e., through the direct heating process of reconnection), a process that has been largely overlooked in earlier studies of ILs.

    The purpose of this study was to clarify the effect of gradual weight bearing (GWB) on regenerating cartilage. We developed a novel external fixation device (EFD) with a controllable weight-bearing system and continuous passive motion (CPM). A full-thickness defect was created by resection of the entire articular surface of the tibial plateau after the EFD was fixed in the rabbit's left knee. In the GWB group (n=6), GWB was started 6 weeks after surgery. In the CPM group (n=6), CPM with EFD was applied in the same manner without GWB. The control group (n=5) received only joint distraction. All rabbits were sacrificed 9 weeks after surgery. The central one-third of the regenerated tissue was assessed and scored blindly using a grading scale modified from the International Cartilage Repair Society visual histological assessment scale. The areas stained by Safranin-O and type II collagen antibody were measured, and the percentage of each area was calculated. There was no significant difference in the histological assessment scale among the groups. The percentage of the type II collagen-positive area was significantly larger in the GWB group than in the CPM group. The present study suggests that optimal mechanical stress, such as GWB, may affect regeneration of cartilage, in vivo. Copyright (c) 2009 Orthopaedic Research Society.

    To study the detailed structural and isotopic heterogeneity of the insoluble organic matter (IOM) of the Murchison meteorite, we performed two types of pyrolytic experiments: gradual pyrolysis and stepwise pyrolysis. The pyrolysates from the IOM contained 5 specific organic groups: aliphatic hydrocarbons, aromatic hydrocarbons, sulfur-bearing compounds, nitrogen-bearing compounds, and oxygen-bearing compounds. The release temperatures and the compositions of these pyrolysates demonstrated that the IOM is composed of a thermally unstable part and a thermally stable part. The thermally unstable part mainly served as the linkage and substituent portion that bound the thermally stable part, which was dispersed throughout the IOM. The linkage and substituent portion consisted of aliphatic hydrocarbons from C 4 to C 8, aromatic hydrocarbons with up to 6 rings, sulfo and thiol groups (the main reservoirs of sulfur in the IOM), and carboxyl and hydroxyl groups (the main reservoirs of oxygen). However, the thermally stable part was composed of polycyclic aromatic hydrocarbons (PAHs) containing nitrogen heterocycles in the IOM. Isotopic data showed that the aliphatic and aromatic hydrocarbons in the linkage and substituent portion were rich in D and 13C, while the thermally stable part was deficient in D and 13C. The structural and isotopic features suggested that the IOM was formed by mixing sulfur- and oxygen-bearing compounds rich in D and 13C (e.g., polar compounds in the interstellar medium (ISM)) and nitrogen-bearing PAHs deficient in D and 13C (e.g., polymerized compounds in the ISM).

    The competition between methane-producing archaea and sulfate-reducing bacteria is an important topic in anaerobic wastewater treatment. In this study, an Up-flow Anaerobic Sludge Blanket Reactor (UASB) was operated for 330 days to evaluate the treatment performance of sulfate-rich wastewater. The effects of competition change between methane production and sulfate reduction on the organic removal efficiency, methane production, and electrons allocation were investigated. Synthetic wastewater was composed of ethanol and acetate with a chemical oxygen demand (COD)/SO 4 2- of 1.0. As a result, the COD removal efficiency achieved in long-term treatment was higher than 90%. During the initial stage, methane production was the dominant reaction. Sulfate-reducing bacteria (SRB) could only partially oxidize ethanol to acetate, and methane-producing archaea (MPA) utilized acetate for methane production. Methane production declined gradually over the long-term operation, whereas the sulfate-reducing efficiency increased. However, UASB performed well throughout the experiment because there was no significant inhibition. After the complete reduction of the sulfate, MPA converted the remaining COD into methane.

    Manoela Fávaro Francisconi

    Full Text Available ABSTRACT Objective: The purpose of this study was to evaluate the deflection forces of Nitinol orthodontic wires placed in different types of brackets: metallic, reinforced polycarbonate with metallic slots, sapphire, passive and active self-ligating, by assessing strength values variation according to gradual increase in wire diameter and deflection and comparing different combinations in the different deflections. Material and Methods: Specimens were set in a clinical simulation model and evaluated in a Universal Testing Machine (INSTRON 3342, using the ISO 15841 protocol. Data were subjected to One-way ANOVA, followed by Tukey tests (p<0.05. Results: Self-ligating brackets presented the most similar behavior to each other. For conventional brackets there was no consistent behavior for any of the deflections studied. Conclusions: Self-ligating brackets presented the most consistent and predictable results while conventional brackets, as esthetic brackets, showed very different patterns of forces. Self-ligating brackets showed higher strength in all deflections when compared with the others, in 0.020-inch wires.

    Infection of swine with virulent porcine reproductive and respiratory syndrome (PRRS) virus induced a rapid, robust antibody response that comprised predominantly nonneutralizing antibodies and waned after approximately 3 months. In contrast, the initial onset of virus-specific interferon (IFN)-γ-secreting cells (SC) in the pig lymphocyte population remained at a fairly low level during this period and then increased gradually in frequency, plateauing at 6 months postinfection. A similar polarization of the host humoral and cellular immune responses was also observed in pigs immunized with a PRRS-modified live virus (MLV) vaccine. Even coadministration of an adjuvant that enhanced the immune response to a pseudorabies (PR) MLV vaccine failed to alter the induction of PRRS virus-specific IFN-γ SC (comprising predominately CD4/CD8α double positive memory T cells with a minority being typical CD4 - /CD8αβ + T cells) and the generation of neutralizing antibodies. Moreover, unlike inactivated PR virus, nonviable PRRS virus did not elicit virus-neutralizing antibody production. Presumably, an intrinsic property of this pathogen delays the development of the host IFN-γ response and preferentially stimulates the synthesis of antibodies incapable of neutralization

    Sugar-sweetened beverages (SSBs) are a major source of free sugar intake and contribute to obesity and obesity-related diseases. Therefore, we analyzed the effect of a gradual sugar reduction strategy within the so-called 'beverage checklist' on free sugar content in beverages on sale in Austria. From 2010 until 2017, data on the amount of free sugar of sweetened beverages (sweetened with sugars, fruit juice and artificial sweeteners) with 0.20-0.75l serving sizes in all main supermarkets and from industry was collected. These data were published annually as the beverage checklist, which displays beverages on sale in Austria. The checklist aims to encourage beverage production with a free sugar content of ≤7.4 g/100 ml and no artificial sweeteners. Free sugar content in the total supply decreased significantly [7.53 (2.86) vs. 6.75 (2.79) g/100 ml; 10.4%; P strategy, conducted by a small non-profit organization, showed a reduction in the mean free sugar content by working with the industry to voluntarily reformulate beverages. More beverages with less added sugar were brought to the market, which implies healthier choices. The challenge now is to further engage the industry and also policy makers to achieve a greater reduction in the future.

    The complex arrangement of the extracellular matrix (ECM) produced by cells during tissue growth, healing and remodelling is fundamental to tissue function. In connective tissues, it is still unclear how both cells and the ECM become and remain organized over length scales much larger than the distance between neighbouring cells. While cytoskeletal forces are essential for assembly and organization of the early ECM, how these processes lead to a highly organized ECM in tissues such as osteoid is not clear. To clarify the role of cellular tension for the development of these ordered fibril architectures, we used an in vitro model system, where pre-osteoblastic cells produced ECM-rich tissue inside channels with millimetre-sized triangular cross sections in ceramic scaffolds. Our results suggest a mechanical handshake between actively contracting cells and ECM fibrils: the build-up of a long-range organization of cells and the ECM enables a gradual conversion of cell-generated tension to pre-straining the ECM fibrils, which reduces the work cells have to generate to keep mature tissue under tension. © 2016 The Author(s).

  5. Experimental and numerical investigation of the flow field in the gradual transition of rectangular to trapezoidal open channels

    2016-01-01

    Full Text Available Transitions are structures that can change geometry and flow velocity through varying the cross-sections of their channels. Under subcritical flow and steady flow conditions, it is necessary to reduce the flow velocity gradually due to increasing water pressure and adverse pressure gradients. Due to the separation of flow and subsequent eddy formation, a significant energy loss is incurred along the transition. This study presents the results of experimental investigations of the subcritical flow along the expansive transition of rectangular to trapezoidal channels. A numerical simulation was developed using a finite volume of fluid (VOF method with a Reynolds stress turbulence model. Water surface profiles and velocity distributions of flow through the transition were measured experimentally and compared with the numerical results. A good agreement between the experimental and numerical model results showed that the Reynolds model and VOF method are capable of simulating the hydraulic flow in open channel transitions. Also, the efficiency of the transition and coefficient of energy head loss were calculated. The results show that with an increasing upstream Froude number, the efficiency of the transition and coefficient of energy head loss decrease and increase, respectively. The results also show the ability of numerical simulation to simulate the flow separation zones and secondary current along the transition for different inlet discharges.

    Little is known about the differences in disabled and nondisabled children's travel patterns, means of transportation, and problems in getting needed transportation. Data from the 2002 Transportation Availability and Use Survey for Persons with Disabilities (NTAUSPD) were used to make comparisons between children (≤17 years) with disabilities and children without disabilities. Disability was defined as meeting the criteria of at least one of three disability measures: responding yes to any of the national disability questions from the 2000 U.S. Census, meeting provisions in the Americans with Disabilities Act (ADA), or receiving special education. Using χ(2) analysis, comparisons were made across the following variables: sex, age, race, number of days leaving home, residency, household income, and availability of transportation. Children with and without disabilities were also compared in terms of their modes of transportation and destinations. Both children with and without disabilities were included in logistic regression models that considered sociodemographics, disability severity, and types of disability and their associations with the problem of getting needed transportation. Disability severity and types of disability were considered as explanatory variables in separate models because of collinearity. Overall, 6.6% (95% confidence interval [CI], 3.9-10.6) of children with disabilities and 4.2% (95% CI, 2.6-6.7) of children without disabilities reported having trouble getting needed transportation. While they did not differ in their mode of transportation for medical visits, local travel, and long-distance travel, children with disabilities used a bus for school travel more frequently than did children without disabilities (P getting needed transportation in the univariable model. However, when disability severity was considered in a multivariable model, only age (odds ratio [OR], 8.59; 95% CI, 2.35-31.31) and income (OR, 6.08; 95% CI, 1.71-21.61) were

    Whereas 'health promotion' is a well-known concept for healthcare professionals, the concept of 'health promotion for people with intellectual disabilities' and its unique associated challenges are not well understood. This article provides a systematic analysis of how health promotion is being conceptualised for people with intellectual disabilities and how health promotion can work best in the light of this group's specific needs and limitations. Rodgers' evolutionary concept analysis. MEDLINE, PsycINFO, CINAHL and SocINDEX were searched using the search terms 'health promotion', 'people with intellectual disabilities' and 'developmental disabilities'. This review includes studies published between 1992 and 2014. A total of 52 articles were included. Health promotion for people intellectual disabilities, as discussed in the literature, focuses on four aspects, namely supporting a healthy lifestyle, providing health education, involving supporters and being person-centred. Antecedents of the concept 'health promotion for people with intellectual disabilities' were healthcare access and sensitised healthcare providers. The outcomes were improved health, being empowered, enhanced quality of life and reduced health disparities.

    2017-09-01

    This study was designed to: (1) determine how many American medical schools include disability awareness in their curriculum, (2) explore the format of disability awareness programs in existence, and (3) understand why some schools do not include disability awareness in their curriculum. An online survey was sent to deans of medical education (or equivalent positions) at accredited allopathic and osteopathic American medical schools (N = 167) in 2015. Seventy-five schools (45%) completed surveys. Fifty-two percent (39/75) reported having a disability awareness program. The most common format was people with disabilities or caregivers speaking in a large group setting. Programs were most likely to focus on adults with physical disabilities. Among schools without a program, the top barriers were no one advocating for inclusion in the curriculum and time constraints. Nearly half of schools without a program expressed interest in adopting an awareness curriculum if one was made available. Such results indicate that efforts should be made to increase the number of schools that provide disability awareness education through increased advocacy and providing additional resources to schools without a curriculum.

    Full Text Available Background The purpose of this study was to determine how to do parenting role's tasks as parents of healthy and disabled children younger than 7 years old in Iran (Arak. Materials and Methods In this cross-sectional study, the parenting role tasks questionnaire was completed for 120 parents of healthy children and 120 parents of disabled children with at least one child with disability and the parents were selected by convenience sampling method. T-test, Mann-Whitney test and analysis of variances was used to compare the scores between parents of healthy and disabled children based on studied variables including child age, parent age, child gender, parent education, family economic status, history of trauma and seizure in children was applied to perform the role of parents. Results: There was a significant difference of parent role in both groups of parents. There was observed a significant relationship between role of healthy children's parents and age of child (r=0.21, P=0.016, but not observed in disabled children's parents. In healthy children, there was no significant correlation between parent's role and maternal age. In contrast, in disabled children, there was found a significant difference (P= 0.04 with correlation coefficient of -0.18 representing the inverse relationship. Moreover, no relationship was found between history of seizure and performance of parenting role's tasks in the group of disabled children (P>0.05. Conclusion The performance of tasks of parenting role in two groups of parents of healthy children and disabled ones in four areas of primary care, education, leisure and improving cognitive level had significant difference. This difference in the area of improving the cognitive level was higher. Due to complications of disability, parents of these children pay more attention to other areas of care except of improving cognitive level. Therefore presence of disabled child has negative effect on the balance of the

    When it is possible that the employee's work ability can be restored through treatment or rehabilitation, disability pension in Finland is granted for a fixed period. We examined which factors are associated with return to work (RTW) after such temporary disability pension. The study included all Finnish residents whose temporary disability pension from the earnings-related pension system started in 2008 (N = 10,269). Competing risks regression analysis was applied to examine register-based determinants for RTW after temporary disability pension due to mental disorders, musculoskeletal diseases, other diseases, and injury over a 4-year follow-up period. The overall cumulative incidence of RTW was 25%. RTW was more probable after temporary disability pension due to injury and musculoskeletal diseases and less probable after temporary disability pension due to mental disorders. Younger age and higher education increased RTW but differences between genders, private and public sector employees, and occupational classes were relatively small. The probability of RTW was higher among those who were employed before their temporary disability pension (subhazard ratio in multivariate analysis 2.41 (95% CI 2.13-2.72) and among the 9% who participated in vocational rehabilitation during their pension [SHR 2.10 (95% CI 1.90-2.31)]. With some exceptions, the results were fairly similar for all diagnostic causes of temporary disability pension. Return to work after temporary disability pension was relatively uncommon. Nevertheless, in all diagnostic groups RTW continued for the whole follow-up period. The low educated and those not employed before temporary disability pension need more support in their RTW. The strong association between vocational rehabilitation and RTW suggests that increasing rehabilitation among those with impaired work ability may promote RTW.

  12. Food insufficiency and food insecurity as risk factors for physical disability among Palestinian refugees in Lebanon: Evidence from an observational study.

    Potential interactions between malnutrition and disability are increasingly recognized, and both are important global health issues. Causal effects working from nutrition to disability and from disability back to nutrition present an empirical challenge to measuring either of these effects. However, disability affects nutrition whatever the cause of disability, whereas nutrition is likelier to affect disease-related disability than war- or work-related disability. This paper investigates the association of food insufficiency with the risk of physical disability. Data on disability by cause allow us to address the difficulty of reverse causality. Multinomial logit regressions of disability by cause on food insufficiency are run using survey data from 2010 on 2575 Palestinian refugee households in Lebanon. Controls include household sociodemographic, health and economic characteristics. Regressions of food insufficiency on disability by cause are also run. Disability has a significant coefficient in regressions of food insufficiency, whatever the cause of disability; but in regressions of disability on food insufficiency, food insufficiency is significant only for disease-related disability (log odds of disease-related disability .78 higher, p = .008). The difference in the results by cause of disability is evidence of a significant association between food insufficiency and disease-related disability, net of any reverse effect from disability to food access. The association between disease-related disability and food insufficiency is statistically significant suggesting that even taking into account feedback from disability to nutrition, nutrition is an effective level of intervention to avert the poverty-disability trap resulting from the impoverishing effect of disability.

    Empirical research has established that children with disabilities are more likely to develop psychopathology than children without disabilities. But too little is known about the association between disability and psychopathology. The aim of this article is to discuss developmental...... psychopathological models that conceptualize the connection between childhood disability and psychopathology. Empirical studies of psychopathology among children with a congenital hearing impairment and children with cerebral palsy will be reviewed, representing in-depth examples of association between disability...... and psychopathology. Both a congenital hearing impairment and cerebral palsy were found to be dominating risk factors for all types of psychopathology, but no relationship was identified between degree of disability and risk of psychopathology. The higher risk cannot be explained by biological impairments alone...

    Full Text Available It is estimated that persons with disabilities represent 15% of the world population. There is a strong link between poverty and disability. Population with disabilities is among the most disadvantaged and discriminated. However, development economic theories have forgotten essential matters about this population, contributing towards their invisibility and poverty. The Capability Approach from a Human Rights based approach brings us a new dimension. The extraordinary costs that arise from a disability and from the psychological, physical and social barriers that persons with disabilities face, contribute to their poverty, lack of freedom and vulneration of human rights, as put forward by current studies on this subject. International co-operation becomes a very valuable tool to be used for the promotion of the rights of persons with disabilities and overcoming poverty.

    Full Text Available Chronic pain is a major health problem and behavioral based treatments have been shown to be effective. However, the availability of these kinds of treatments is scarce and internet-based treatments have been shown to be promising in this area. The objective of the present systematic review is to evaluate internet-based interventions for persons with chronic pain. The specific aims are to do an updated review with a broad inclusion of different chronic pain diagnoses and to assess disability and pain and also measures of catastrophizing, depression and anxiety. A systematic search identified 891 studies and 22 trials were selected as eligible for review. Two of the selected trials included children/youth and five included individuals with chronic headache and/or migraine. The most frequently measured domain reflected in the primary outcomes was interference/disability, followed by catastrophizing. Result across the studies showed a number of beneficial effects. Twelve trials reported significant effects on disability/interference outcomes and pain intensity. Positive effects were also found on psychological variable such as catastrophizing, depression and anxiety. Several studies (n = 12 were assessed to have an unclear level of risk bias. The attrition levels ranged from 4% to 54% where the headache trials had the highest drop-out levels. However, findings suggest that internet-based treatments based on cognitive behavioural therapy (CBT are efficacious measured with different outcome variables. Results are in line with trials in clinical settings. Meta-analytic statistics were calculated for interference/disability, pain intensity, catastrophizing and mood ratings. Results showed that the effect size for interference/disability was Hedge's g = −0.39, for pain intensity Hedge's g = −0.33, for catastrophizing Hedge's g = −0.49 and for mood variables (depression Hedge's g = −0.26.

    This introduction to the special issue on presidential disability and succession focuses on the distinctly positive contributions that invocations of the Twenty-Fifth Amendment have made to American political life since the Amendment's ratification in 1967. It also underlines the importance for Presidents, their family members and aides to understand the necessity for putting the welfare of the country first, above all else-even at times above the wishes of a disabled Chief Executive. As the articles in this special issue make clear, the Twenty-Fifth Amendment provides an effective constitutional mechanism by which the country's well-being can be maintained while simultaneously showing compassion and respect for a disabled leader. The idea for this issue emerged from a conference organized by Professor Robert E. Gilbert focusing on presidential disability and succession held on the campus of Northeastern University in April 2014. Papers from the conference assembled here clarify and add to the historical record about presidential inability while illuminating the many political, legal, and constitutional contingencies that future presidential administrators may face. Contributors to this issue have varied disciplinary and professional backgrounds, including expertise in American politics, constitutional law, the presidency and vice presidency, presidential impairment, and, of course, the Twenty-Fifth Amendment to the Constitution.

    Full Text Available This essay is an attempt at investigating visible forms of complex, indeed controversial embodiment, with the specific intention of concentrating on the ways they interrogate delicate issues such as disability, masculinity and prosthetic sport performance. I intend to sound the shifting boundaries between dis-ability and super-ability as manifested in iconic figures such as Stelarc and, in other fields, Oscar Pistorius, whose unsteady position as privileged/disabled bladerunner seems to require – and indeed to gather – particularly intense scrutiny. I shall introduce a few contemporary discourses on corporeality and embodiment, which focus on the ‘troubling’ nature of auxiliary organs Freud refers to in the much contended paragraph I adopt as epigraph and guiding procedural light; I shall move from Butler and Giddens to Jean-Luc Nancy’s work on transplants and/as prostheses to include theoretical debates on disintegrating embodiment and disability studies, in order to proceed towards an analysis of the short-circuiting of allegedly secure practices of (masculine embodiment in sport culture and theory.

    Full Text Available Introduction. A review of Polish and international literature does not give a clear indication of the level of anaerobic capacity that sailors with disabilities demonstrate with regard to their functional capacities. This study sought to determine differences in functional capacity levels between sailors from three medical and functional groups. Material and methods. The research was carried out during a sports camp at the National Sailing Centre in Górki Zachodnie in 2014. Eighteen males with locomotor disabilities were included in the study. The athletes were members of the National Team of Sailors with Disabilities of the Polish Yachting Association. The sportsmen competed in the Skud 18 and 2.4mR Paralympic classes. A 30-second Wingate test for upper limbs was employed in the study. Results. Significant differences in mean power (MP values were noted between the groups under investigation. The group of wheelchair sailors with improper core stability (A and the group of wheelchair sailors with proper core stability (B had significantly lower scores than the group of study participants who were able to move freely, that is to walk (C. Conclusions. The study revealed that a 30-second anaerobic capacity test performed on an arm ergometer differentiated disabled sailors from selected groups in terms of mean power. Research on anaerobic capacity may be used to verify the current classification in Paralympic sailing and will make it possible to differentiate present competition categories.

    Full Text Available Abstract Aims: Intellectual disability is a condition characterised by the inability of a person to undertake normal psychological activities. The purpose of this study was to systematically review the intellectual disability in children and discuss the implications of different environmental and genetic factors, which describe particular categories of intellectual disable cases. Information & Methods: This systematic review was performed in 2014 by searching the existing literature in PubMed database in the scope of “intellectual disability in children”. 38 articles written from 1987 to 2014 were selected and surveyed for review. Findings: The prevalence of ID in the general population is estimated to be approximately 1%. ID disorder is multi-causal, encompassing all factors that interfere with brain development and functioning. Causes usually are classified according to the time of the insult, as prenatal, perinatal, and postnatal or acquired. Some causes, such as environmental toxins or endocrine disorders, may act at multiple times. Others, such as genetic disorders, have different manifestations during postnatal development. The outcome for ID is variable and depends upon the aetiology, associated conditions, and environmental and social factors. The goals of management of ID are to strengthen areas of reduced function, minimize extensive deterioration in mental cognitive and adaptability, and lastly, to promote optimum or normal functioning of the individuals in their community. Conclusion: Prominent features of ID include significant failures in both intellectual functioning and adaptive behaviour, which comprises daily social and practical life skills, commencing earlier in life.

    Intellectual disability may impact on an individual's capacity to parent a child effectively. Research suggests that the number of intellectually disabled people with children is increasing. Children of parents with intellectual disabilities may be at increased risk of neglectful care which could lead to health, developmental and behavioural problems, or increased risk of intellectual disability.However, there is some indication that some parents with intellectual disabilities are able to provide adequate child care if they are given appropriate training and support to do so. To assess the effectiveness of parent training interventions to support the parenting of parents with intellectual disabilities We searched the following databases: Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library), MEDLINE, EMBASE, CINAHL, PsycINFO, ASSIA, Sociological Abstracts, Dissertation Abstracts International, MetaRegister of Controlled Trials, and ZETOC. Randomised controlled trials comparing parent training interventions for parents with intellectual disabilities with usual care or with a control group. Outcomes of interest were: the attainment of parenting skills specific to the intervention, safe home practices and the understanding of child health. Two review authors independently assessed risk of bias and undertook data extraction. Three trials met the inclusion criteria for this review but no meta-analysis was possible. One study reported improved maternal-child interaction following group parent training compared with the control group. The second study reported some improvements in parents knowledge of life threatening emergencies, ability to recognise dangers and identify precautions and smaller improvements in their ability to implement precautions, use medicines safely and recognise child illness and symptoms. The third study reported improvement in child care and safety skills following the intervention. There is some risk of bias in the

    This article describes a system of diagnostic categories that Medicaid programs can use for adjusting capitation payments to health plans that enroll people with disability. Medicaid claims from Colorado, Michigan, Missouri, New York, and Ohio are analyzed to demonstrate that the greater predictability of costs among people with disabilities makes risk adjustment more feasible than for a general population and more critical to creating health systems for people with disability. The application of our diagnostic categories to State claims data is described, including estimated effects on subsequent-year costs of various diagnoses. The challenges of implementing adjustment by diagnosis are explored. PMID:10172665

  2. Preschool Children’s Memory for Word Forms Remains Stable Over Several Days, but Gradually Decreases after Six Months

    Directory of Open Access Journals (Sweden)

    Katherine Ruth Gordon

    2016-09-01

    Full Text Available Research on word learning has focused on children’s ability to identify a target object when given the word form after a minimal number of exposures to novel word-object pairings. However, relatively little research has focused on children’s ability to retrieve the word form when given the target object. The exceptions involve asking children to recall and produce forms, and children typically perform near floor on these measures. In the current study, 3- to 5-year-old children were administered a novel test of word form that allowed for recognition memory and manual responses. Specifically, when asked to label a previously trained object, children were given three forms to choose from: the target, a minimally different form, and a maximally different form. Children demonstrated memory for word forms at three post-training delays: 10 minutes (short-term, 2 to 3 days (long-term, and 6 months to 1 year (very long-term. However, children performed worse at the very long-term delay than the other time points, and the length of the very long-term delay was negatively related to performance. When in error, children were no more likely to select the minimally different form than the maximally different form at all time points. Overall, these results suggest that children remember word forms that are linked to objects over extended post-training intervals, but that their memory for the forms gradually decreases over time without further exposures. Furthermore, memory traces for word forms do not become less phonologically specific over time; rather children either identify the correct form, or they perform at chance.

    The forced swim test (FST) is a pre-clinical test to short and long term treatment with antidepressant drugs (ADT), which requires between-subject designs. Herein a modified protocol of the FST using within-subject design (repeated rat-FST) was evaluated. Male Wistar rats were submitted to 15 min of swimming (Day 1: pretest) followed by three subsequent 5 min-swimming tests one week apart (Day 2: test, Day 7: retest 1, Day 14: retest 2). To determine the temporal and factorial characteristics of the variables scored in the repeated rat-FST, the protocol was carried out in untreated animals (E1). To validate the method, daily injections of Fluoxetine (FLX, 2.5mg/kg, i.p.) or saline were given over a 2-week period (E2). Tests and retests have been videotaped for further register of the latency, frequency and duration of behaviors. Over retesting the latency to immobility decreased whereas duration of immobility tended to increase. Factorial analysis revealed that the test, the retest 1 as well as the retest 2 have variables suitable to detection of antidepressant-like effects of ADT. Compared to saline, FLX chronically administrated reduced duration of immobility whereas increased duration of swimming in retest 2. The data suggest that repeated rat-FST detected the gradual increase in the efficacy of low doses of FLX over time. Therefore, repeated rat-FST seemed suitable to detect short and long term effects of selective serotonin reuptake inhibitors, or other ADT, thus reducing the number of animals used in the screenings of this type of compounds. © 2010 Elsevier B.V.

  4. Correlation Analyses Between the Characteristic Times of Gradual Solar Energetic Particle Events and the Properties of Associated Coronal Mass Ejections

    It is generally believed that gradual solar energetic particles (SEPs) are accelerated by shocks associated with coronal mass ejections (CMEs). Using an ice-cream cone model, the radial speed and angular width of 95 CMEs associated with SEP events during 1998 - 2002 are calculated from SOHO/LASCO observations. Then, we investigate the relationships between the kinematic properties of these CMEs and the characteristic times of the intensity-time profile of their accompanied SEP events observed at 1 AU. These characteristic times of SEP are i) the onset time from the accompanying CME eruption at the Sun to the SEP arrival at 1 AU, ii) the rise time from the SEP onset to the time when the SEP intensity is one-half of peak intensity, and iii) the duration over which the SEP intensity is within a factor of two of the peak intensity. It is found that the onset time has neither significant correlation with the radial speed nor with the angular width of the accompanying CME. For events that are poorly connected to the Earth, the SEP rise time and duration have no significant correlation with the radial speed and angular width of the associated CMEs. However, for events that are magnetically well connected to the Earth, the SEP rise time and duration have significantly positive correlations with the radial speed and angular width of the associated CMEs. This indicates that a CME event with wider angular width and higher speed may more easily drive a strong and wide shock near to the Earth-connected interplanetary magnetic field lines, may trap and accelerate particles for a longer time, and may lead to longer rise time and duration of the ensuing SEP event.

    Full Text Available Under freeze-thaw cycles, the relationship between rock microstructure deterioration and its macroscopic mechanical characteristics has drawn extensive attention from engineers. With the objective to incorporate freeze-thaw cycle experiment into headrace tunnel engineering, in the present study two groups of andesite rock samples in different states are tested under the conditions of the lowest freezing temperature of –40 ℃ and the thawing temperature of 20 ℃. Damage detection was performed by magnetic resonance imaging for the interior microstructure of rock samples subject to different freeze-thaw cycles, and the relationship between the sample mechanical properties and gradual deterioration of rock microstructures was discussed. The results demonstrate evident influence of freeze-thaw cycle on the damage and deterioration of internal pore structure in andesite, and the rock uniaxial compressive strength and elasticity modulus exhibit a decreasing trend with the increase of freeze-thaw cycles. After 40 cycles, the strength of naturally saturated rock samples decreases by 39.4% (equivalent to 69.4 MPa and the elasticity modulus drops by 47.46% (equivalent to 3.27 GPa. For rock samples saturated by vacuum, 40 freeze-thaw cycles lead to a decrease of 36.86% (equivalent to 58.2 MPa in rock strength and a drop of 44.85% (equivalent to 2.83 GPa in elasticity modulus. Therefore, the test results quantitatively elucidate the substantial influence of freeze-thaw cycle on the damage and deterioration of internal structure in andesite.

    Full Text Available Filmes finos de PMMA foram preparados a partir de solução e expostos ao plasma de CF4+H2, visando mudar o Índice de Refração (I.R. da superficie do PMMA através da fluoração. Os filmes de PMMA expostos ao plasma, denominados de filmes ópticos, foram caracterizados usando as técnicas: ESCA, RBS, FTIR, gravimetria, ângulo de contato, refratometria e elipsometria. Os resultados revelaram que as superfícies de PMMA foram revestidas com uma fina camada de hidrofluorcarbono polimérico, com espessuras variando entre 0,43 e 0,49mim. A camada de hidrofluorcarbono polimérico na superfície do PMMA foi responsável pela significante redução do seu I.R. de 1,49 para 1,43. A concentração de flúor nessa camada aumentou gradualmente em função da profundidade, sendo menor na sua superficie. Como o átomo de flúor é responsável pela redução do I.R., concluiu-se que o I.R. no revestimento fluorado do filme óptico variou também de forma gradual. A técnica de polimerização por plasma de CF4+H2 mostrou-se útil para modificar in situ os I.R. da superfíces de guias de ondas e fibras ópticas poliméricas, visando reduzir as perdas e aumentar a velocidade de transmissão de dados.

    Full Text Available Women with disabilities are doubly discriminated against and socially excluded: through gender and disability. In order to perform an in-depth analysis of their actual situation, it is necessary to understand which models have been able to provide legal and political answers to this issue. Hence, the feminist model can be identified, on the basis of which we might elaborate upon its possible ties with the social model of disability. This study shows the correctness of feminist conclusions when dealing with inequality between men and women, but it also proves the inaccurateness of feminism in its approach on women with disabilities.

    To compare workers with and without disabilities on their reported workplace hazard exposure and the presence of occupational health and safety vulnerability factors. Working-aged adults in Ontario or British Columbia were recruited to participate in a cross-sectional survey (n = 1988). Self-reported measures included demographic factors, work-related variables, perceived level of activity limitation at work, and presence of work safety vulnerability factors utilizing a novel framework. Reporting a disability at work was significantly associated with greater hazard exposure than those without a disability. In addition, those reporting a disability at work were more likely to be employed in conditions where hazard exposure was combined with inadequate policies and procedures, or hazard exposures were combined with inadequate empowerment. Work safety vulnerability is one way that health inequalities can be perpetuated even among those with disabilities who have found work. Our results suggest that employers and policy makers need to focus on assessing and addressing hazard exposures and targeting occupational health and safety resources in the workplace in a way that includes workers with disabilities. Implications for Rehabilitation Workers with disabilities experience greater hazard exposure than those without a disability. Those with moderate and severe disabilities reported occupational health and safety vulnerability, suggesting that workplace accommodations should be available to a broader range of disability levels. It appears that, above and beyond standard safety procedures, providing workplace accommodations for people with disabilities may further reduce their hazard exposure and improve their safety.

    Information on disability is essential for the government to formulate policies, allocate adequate resources and implement appropriate programmes. We aimed to estimate the prevalence of disability and describe the types of disability by gender, age and geographical regions in Tamil Nadu, India. We analysed the 2011 Census cross-sectional survey data of Tamil Nadu. Age-adjusted disability rates and disability rates per 100 000 population were calculated. There were 1 179 963 disabled individuals in Tamil Nadu in 2011, a disability rate of 1635 per 100 000 population. Disability in movement, hearing and sight individually accounted for 24%, 19% and 11% of the total disability, respectively. Sixteen districts had disability rates above the state average. As age advanced, disability rates increased; the highest disability rate of 2533 per 100 000 was among people aged 60 years and above. The disability rates were higher in males compared to females (1819 v. 1451 per 100 000). Rural areas had higher disability areas compared to urban (1670 v. 1599 per 100 000). Currently married, working populations and literate populations had lower disability rates. Disability rate in the Scheduled Castes was higher at 1763 per 100 000 compared to the Scheduled Tribes and other social groups. Multiple disability was high in the age groups 0-19 years and 60 years and above. Physical or mental disability was observed in 1.6% of the population of Tamil Nadu. Research is warranted to identify underlying causes and interventions to reduce the burden of disability in the state.

    The intent of this article is to assess the current state of Emergency Warning capabilities in the United States and make recommendations on what needs to be done to cost effectively establish a National Emergency Warning System to best serve the people of the United States, including those with disabilities. As part of this assessment, terminology will be defined, existing systems will be examined, critical needs and functions will be explained, and recommendations made for a system to deliver emergency messages to those people immediately at risk from natural and human-caused disasters in a timely and effective manner, regardless of location or situational circumstance. The assessment will include the needs and available technologies for delivering emergency warnings to people with disabilities, which are generally little understood, poorly addressed, and often ignored.

    Disabled women suffer socio-labour discrimination because of both their gender and their disability. The situation is gradually improving, thanks to the national and supranational organisations, which in the past few decades have made considerable progress in improving the legislation, providing financial resources and encouraging social awareness. Despite this, few studies quantify this double discrimination in order to permit the evaluation of the socio-labour situation of this group of people. This scarcity is even more pronounced for rural areas, where many other factors hinder the integration of disabled women into the labour market and generate some specific problems that the specialist literature seldom addresses. The current work presents the results of a survey on the socio-economic situation of disabled women in a strongly rural area: the Spanish region of Castilla-La Mancha. It stresses the fundamental difficulties of these women in integrating into the labour market and the most urgent political measures needed to help this group.

  14. Just What Is the Disability Perspective on Disability?

    Shakespeare, Tom

    2016-05-01

    In the helpful article "Why Bioethics Needs a Disability Moral Psychology," Joseph Stramondo adds to the critique of actually existing bioethics and explains why disability activists and scholars so often find fault with the arguments of bioethicists. He is careful not to stereotype either community-rightly, given that bioethicists endorse positions as disparate as utilitarianism, deontology, virtue ethics, and feminist ethics, among others. Although Stramondo never explicitly mentions utilitarians or liberals, it seems probable that these are the main targets of his discontent. The disability community, as he concedes, is also a broad church. Yet for this reason, I do not believe that you can read off positions on bioethics questions from either disability embodiment or disability organization affiliation. © 2016 The Hastings Center.

    Women and girls with disabilities have historically been denied the freedom to make their own choices in matters relating to their reproduction. In the healthcare sector they experience multiple discriminatory practices. Women and girls with intellectual disabilities are particularly vulnerable to coerced or forced medical interventions. The present article considers the contribution the Convention on the Rights of Persons with Disabilities makes towards affirming the rights of women and girls with disabilities to enjoy reproductive autonomy, including autonomy related to reproductive health, on an equal basis with individuals without disabilities. The Convention is paradigm-setting in its maximal approach to affirming the rights of individuals with disabilities to make autonomous choices under conditions of equality and non-discrimination. The Convention is the first human rights treaty to clearly affirm that impairment of decision-making skills is not a justification for depriving a person with cognitive or intellectual disability of legal capacity. © 2017 International Federation of Gynecology and Obstetrics.

    2004-04-01

    Nursing conceptualizes disability from largely medical and individual perspectives that do not consider its social dimensions. Disabled people are critical of this paradigm and its impact on their health care. The aims of this paper are to review the International Classification of Functioning, Disability and Health (ICF), including its history and the theoretical models upon which it is based and to discuss its relevance as a conceptual framework for nursing. The paper presents a critical overview of concepts of disability and their implications for nursing and argues that a broader view is necessary. It examines ICF and its relationship to changing paradigms of disability and presents some applications for nursing. The ICF, with its acknowledgement of the interaction between people and their environments in health and disability, is a useful conceptual framework for nursing education, practice and research. It has the potential to expand nurses' thinking and practice by increasing awareness of the social, political and cultural dimensions of disability.

    Over one-third of breast cancer survivors experience upper extremity disability. Black women present with factors associated with greater upper extremity disability, including: increased body mass index (BMI), more advanced disease stage at diagnosis, and varying treatment type compared with Whites. No prior research has evaluated the relationship between race and upper extremity disability using validated tools and controlling for these factors. Data were drawn from a survey study among 610 women with stage I-III hormone receptor positive breast cancer. The disabilities of the arm, shoulder and hand (QuickDASH) is an 11-item self-administered questionnaire that has been validated for breast cancer survivors to assess global upper extremity function over the past 7 days. Linear regression and mediation analysis estimated the relationships between race, BMI and QuickDASH score, adjusting for demographics and treatment types. Black women (n = 98) had 7.3 points higher average QuickDASH scores than White (n = 512) women (p disability by 40 %. Even several years post-treatment, Black breast cancer survivors had greater upper extremity disability, which was partially mediated by higher BMIs. Close monitoring of high BMI Black women may be an important step in reducing disparities in cancer survivorship. More research is needed on the relationship between race, BMI, and upper extremity disability.

    This study investigates the interaction between obesity and disability and its impact on the levels of job satisfaction reported by older workers (aged 50-64) in ten European countries (Denmark, Sweden, Austria, Belgium, France, Germany, The Netherlands, Switzerland, Italy and Spain). Using longitudinal data from the Survey of Health, Ageing and Retirement in Europe for the years 2004, 2007 and 2011, we estimate a job satisfaction equation which includes a set of explanatory variables measuring worker's obesity and disability status (non-disabled, non-limited disabled, and limited disabled). The results show that, after controlling for other variables, obese workers are more likely to be satisfied with their jobs as compared to those workers with normal weight (0.066 points). In addition, being limited disabled or having poor health contribute to reducing (by 0.082 and 0.172 points, respectively) this positive effect of being obese on job satisfaction. However, we do not find any differential effect of obesity on job satisfaction by disability status, except for those underweight individuals who are not limited in their daily activities. Overall, these findings support the hypothesis of lower expectations about jobs for obese workers, especially if they also have poor health. Copyright © 2015 Elsevier B.V. All rights reserved.

    Diabetic Retinopathy (DR) remains a common and one of the major causes of blindness in the developed and western societies. The same situation is shown in emerging economic areas (5,6). In sub-Saharan Africa (SSA) however, the issues of visual disability due to diabetes mellitus (DM) are overshadowed by the presence of the prevalent and common nutritional deficiency diseases and eye infections This clinic-based study was conducted to determine whether diabetic retinopathy is independently related to visual disability in black patients with diabetes mellitus (DM) from Kinshasa, Congo. A total of 299 urban patients with DM and low income including 108 cases of visual disability and matched for time admission and DM type to 191 controls, were assessed. Demographic, clinical, and ophthalmic data were assessed using univariate and multivariate analyses. Age ≥60 years, female sex, presence of diabetic retinopathy (DR), proliferative DR, shorter DM duration, glaucoma, macular oedema, diabetic nephropathy were the univariate risk factors of visual disability. Using logistic regression model, visual disability was significantly associated with female sex and diabetic retinopathy. The risk of visual disability is 4 times higher in patients with diabetic retinopathy and 2 times higher in females with DM. Therefore, to prevent further increase of visual disability, the Congolese Ministry of Health should prioritize the eye care in patients with DM.

    Full Text Available BACKGROUND Disability and disability certificates are like double-edged swords. On one hand, a non-qualifying individual may avail certain benefits and privileges reserved for disabled person due to over calculation; and on other hand, a deserving disabled may not be able to get benefit out of the granted opportunities due to under calculation. This study was thus undertaken to analyse the disability certificates issued at our institution to determine the fallacies that are evident in the criteria for disability assessment. METHODOLOGY 500 cases of permanent physical disability (PPD resulting from road traffic accidents (RTA satisfying the inclusion and exclusion criteria were re-examined after final assessment of disability and the assessed disability was reviewed in terms of the defect in function of body; the total percentage of disability allotted to the candidate and the appropriateness of the assessed value in relation to the hindrance caused to daily routine. OBSERVATIONS No discrepancy was noted in 355 cases, but in rest of 145 cases a number of discrepancies were noted in relation to the above said criteria of comparison. Out of these, in 20% cases, the percentage of disability did not include a note of the total impact of the disability on physical, mental, social life of the disabled person resulting in more non-functioning as compared to the calculated resulting permanent disability. In rest 30% cases with discrepancies, calculated percentage had ill correlation between malfunctioning of the body part and its overall calculation in relation to the body as a whole. Rest 50% cases were those where similar malfunctioning resulting from different lesions was assessed differently resulting in different percentages of permanent physical disabilities. CONCLUSION A serious revision of these guidelines in lieu of discrepancies must be ensued to benefit one and all equally and to ensure uniformity in the process which is a gateway to

    Full Text Available Women have suffered from drug abuse for conturies, although formal Treatment assistance for women has been recognized as important only during the past few decades. The nature and underlying reasons for women's drug abuse differ from men’s behavior in many ways. It is finally understood that research on men will not simply translate into effective solutions for women as well. Here deal with the many issues that can arise in working with disabled women suffered from drug abuse because biologically, Culturally, and socially, their experience is different from that of men and other women and key theme For this discourse is that a woman who suffered from drug abuse is first and foremost a woman. Disabled women also have specific issues that must acknowledge and incorporate into the counseling, social work and other experince, so, here review is based on more than 25 years of the collective experience and firsthand knowledge of Monique Cohen and their Counselors at The CASPAR outpatient Clinic in Cambridge, Massachusett (2000 about women with drug abuse and alcoholism. The clinic Provides omprehensive substance abuse treatment to Individuals and Families struggling with either one or multiple addictions.

  6. Intellectual disability and homelessness.

    The association between poverty and intellectual disability (ID) has been well documented. However, little is known about persons with ID who face circumstances of extreme poverty, such as homelessness. This paper describes the situation of persons with ID who were or are homeless in Montreal and are currently receiving services from a team dedicated to homeless persons. (1) To describe the characteristics, history and current situation of these persons; and (2) to report within-group differences as a function of gender and current residential status. The data were collected from files using an anonymous chart summary. Descriptive statistics on the whole sample (n = 68) and inferential statistics on cross-tabulations by gender and residential status were performed. Persons with ID exhibited several related problems. Some of these persons, primarily women, experienced relatively short periods of homelessness and their situations stabilised once they were identified and followed up. Other persons with ID experienced chronic homelessness that appeared to parallel the number and severity of their other problems. When compared with a previous epidemiological study of the homeless in Montreal, the population of homeless persons with ID differed from the overall homeless population in a number of respects. The results suggest prevention and intervention targets. The need for epidemiological research appears particularly clear in light of the fact that below-average intellectual functioning has been identified as a risk factor for homelessness and a predisposing factor for vulnerability among street people. © 2011 The Authors.

    These cases represent individuals who feel they have a severe impairment and are "disabled." They have been labeled with fibromyalgia. They are truly distressed. Their symptoms, their courses, are more chronic and refractory than those of medically ill patients, and they are high users of medical services, laboratory investigations, and surgical procedures. These patients see multiple providers simultaneously and frequently switch physicians. They are difficult to care for, and they reject psychosocial factors as an influence on their symptoms. Such persons "see themselves as victims worthy of a star appearance on the Oprah Winfrey show. A sense of bitterness emerges...." Shorter, a historian, believes that fibromyalgia is "heaven-sent to doctors as a diagnostic label for pain patients who display an important neurotic component in their illness. Our culture increasingly encourages patients to conceive vague and nonspecific symptoms as evidence of real disease and to seek specialist help for them; and the rising ascendancy of the media and the breakdown of the family encourage patients to acquire the fixed belief that they have a given illness...." Regarding the finding of "disability," this is a social construct, and many authors believe it is society and the judicial system who must decide who can work. To remain objective, the physician should report the objective clinical information. Physicians need not and should not sit in judgment of the veracity of another human being.

  14. Understanding intellectual disability through RASopathies.

    San Martín, Alvaro; Pagani, Mario Rafael

    2014-01-01

    Intellectual disability, commonly known as mental retardation in the International Classification of Disease from World Health Organization, is the term that describes an intellectual and adaptive cognitive disability that begins in early life during the developmental period. Currently the term intellectual disability is the preferred one. Although our understanding of the physiological basis of learning and learning disability is poor, a general idea is that such condition is quite permanent. However, investigations in animal models suggest that learning disability can be functional in nature and as such reversible through pharmacology or appropriate learning paradigms. A fraction of the cases of intellectual disability is caused by point mutations or deletions in genes that encode for proteins of the RAS/MAP kinase signaling pathway known as RASopathies. Here we examined the current understanding of the molecular mechanisms involved in this group of genetic disorders focusing in studies which provide evidence that intellectual disability is potentially treatable and curable. The evidence presented supports the idea that with the appropriate understanding of the molecular mechanisms involved, intellectual disability could be treated pharmacologically and perhaps through specific mechanistic-based teaching strategies.

    A review of existing measurement instruments was conducted to examine their suitability to measure disability prevalence and assess quality of life, protection of disability rights and community participation by people with disabilities, specifically within the context of development programs in low and middle-income countries. From a search of PubMed and the grey literature, potentially relevant measurement instruments were identified and examined for their content and psychometric properties, where possible. Criteria for inclusion were: based on the WHO's International Classification of Functioning Disability and Health (ICF), used quantitative methods, suitable for population-based studies of disability inclusive development in English and published after 1990. Characteristics of existing instruments were analysed according to components of the ICF and quality of life domains. Ten instruments were identified and reviewed according to the criteria listed above. Each version of instruments was analysed separately. Only three instruments included a component on quality of life. Domains from the ICF that were addressed by some but not all instruments included the environment, technology and communication. The measurement instruments reviewed covered the range of elements required to measure disability-inclusion within development contexts. However no single measurement instrument has the capacity to measure both disability prevalence and changes in quality of life according to contemporary disability paradigms. The review of measurement instruments supports the need for developing an instrument specifically intended to measure disability inclusive practice within development programs. Implications for Rehabilitation Surveys and tools are needed to plan disability inclusive development. Existing measurement tools to determine prevalence of disability, wellbeing, rights and access to the community were reviewed. No single validated tool exists for population

  16. Model of Intellectual Disability and the Relationship of Attitudes Towards the Sexuality of Persons with an Intellectual Disability.

    2013-06-01

    The following article discusses the relationship between the model of intellectual disability and the attitudes towards sexuality of people with disabilities. This correlation has been verified during the author's own research conducted on students of several medical faculties such as nursing, public health, emergency medical services and physiotherapy. Tools of the author's design have been used in the research. Likert-type scale "Perspective of intellectual disability" has been used to determine the model of disability seen from the medical (individual) or social perspective. To examine the attitudes towards sexuality two tools of the author's own design have been used: a Likert-type scale "The essence of sexuality in persons with an intellectual disability" which has been used to analyze the cognitive aspect of the attitudes, and a semantic differential with notions concerning physical and psychosocial aspects of sexuality including the affective-evaluative aspect. As expected, significant correlations have been found between the model and the attitudes both in the cognitive and the affective-evaluative aspect. Higher scores for the individual model correlated with: (a) lover scores for most aspects of sexuality of people with intellectual disability, (b) perceiving them as asexual, (c) biological determinism in the sexual sphere. The social model concurred with positive values given to sexuality of people with intellectual disability and its normalization in the sphere of its determinants and symptoms.

    Smoking, the leading cause of disease and death in the United States, has been linked to a number of health conditions including cancer and cardiovascular disease. While people with a disability have been shown to be more likely to report smoking, little is known about the prevalence of smoking by type of disability, particularly for adults younger than 50 years of age. We used data from the 2009-2011 National Health Interview Survey to estimate the prevalence of smoking by type of disability and to examine the association of functional disability type and smoking among adults aged 18-49 years. Adults with a disability were more likely than adults without a disability to be current smokers (38.8% vs. 20.7%, p<0.001). Among adults with disabilities, the prevalence of smoking ranged from 32.4% (self-care difficulty) to 43.8% (cognitive limitation). When controlling for sociodemographic characteristics, having a disability was associated with statistically significantly higher odds of current smoking (adjusted odds ratio = 1.57, 95% confidence interval 1.40, 1.77). The prevalence of current smoking for adults was higher for every functional disability type than for adults without a disability. By understanding the association between smoking and disability type among adults younger than 50 years of age, resources for cessation services can be better targeted during the ages when increased time for health improvement can occur.

    2016-10-07

    Over twenty million persons with disability in India are increasingly being offered poverty alleviation strategies, including employment programs. This study employs a spatial analytic approach to identify correlates of employment among persons with disability in India, considering sight, speech, hearing, movement, and mental disabilities. Based on 2001 Census data, this study utilizes linear regression and spatial autoregressive models to identify factors associated with the proportion employed among persons with disability at the district level. Models stratified by rural and urban areas were also considered. Spatial autoregressive models revealed that different factors contribute to employment of persons with disability in rural and urban areas. In rural areas, having mental disability decreased the likelihood of employment, while being female and having movement, or sight impairment (compared to other disabilities) increased the likelihood of employment. In urban areas, being female and illiterate decreased the likelihood of employment but having sight, mental and movement impairment (compared to other disabilities) increased the likelihood of employment. Poverty alleviation programs designed for persons with disability in India should account for differences in employment by disability types and should be spatially targeted. Since persons with disability in rural and urban areas have different factors contributing to their employment, it is vital that government and service-planning organizations account for these differences when creating programs aimed at livelihood development.

    In the study described herein, we investigated and explored the association between wealth inequality and the risk of mental disability in the Chinese population. We used nationally represented, population-based data from the second China National Sample Survey on Disability, conducted in 2006. A total of 1,724,398 study subjects between the ages of 15 and 64, including 10,095 subjects with mental disability only, were used for the analysis. Wealth status was estimated by a wealth index that was derived from a principal component analysis of 10 household assets and four other variables related to wealth. Logistic regression analysis was used to estimate the odds ratio (OR) and 95% confidence interval (CI) for mental disability for each category, with the lowest quintile category as the referent. Confounding variables under consideration were age, gender, residence area, marital status, ethnicity, education, current employment status, household size, house type, homeownership and living arrangement. The distribution of various types and severities of mental disability differed significantly by wealth index category in the present population. Wealth index category had a positive association with mild mental disability (p for trend disability (p for trend disability when all severities of mental disability were taken into consideration. This study's results suggest that wealth is a significant factor in the distribution of mental disability and it might have different influences on various types and severities of mental disability.
