    It has been suggested that supplementation of indoor air with negative ions can improve air quality. This study examined the effects of a negative ion-generator device on air contaminants and symptom reporting in two office buildings. Separate sets of functional and nonfunctional negative ion generators were monitored using a double blind, crossover design involving two 5-week exposure periods. There were no detectable direct or residual effects of negative ion generator use on air ion levels, airborn particulates, carbon dioxide levels, or symptom reporting. Symptom reporting declined at both sites initially and appeared to be consistent with placebo effect. Job dissatisfaction was an apparent contributor to symptom reporting, with a magnitude comparable to presumed effects of air quality. Further testing of such devices is needed before they should be considered for office air quality problems.

    Grass vegetation has been recommended for use in the prevention and control of soil erosion because of its dense sward characteristics and stabilizing effect on the soil. A general assumption is that grassland environments suffer from minimal soil erosion and therefore present little threat to the water quality of surface waters in terms of sediment and sorbed contaminant pollution. Our data question this assumption, reporting results from one hydrological year of observations on a field-experiment monitoring overland flow, drain flow, fluxes of suspended solids, total phosphorus (TP), and molybdate-reactive phosphorus (<0.45 mum) in response to natural rainfall events. During individual rainfall events, 1-ha grassland lysimeters yield up to 15 kg of suspended solids, with concentrations in runoff waters of up to 400 mg L(-1). These concentrations exceed the water quality standards recommended by the European Freshwater Fisheries Directive (25 mg L(-1)) and the USEPA (80 mg L(-1)) and are beyond those reported to have caused chronic effects on freshwater aquatic organisms. Furthermore, TP concentrations in runoff waters from these field lysimeters exceeded 800 mug L(-1). These concentrations are in excess of those reported to cause eutrophication problems in rivers and lakes and contravene the ecoregional nutrient criteria in all of the USA ecoregions. This paper also examines how subsurface drainage, a common agricultural practice in intensively managed grasslands, influences the hydrology and export of sediment and nutrients from grasslands. This dataset suggests that we need to rethink the conceptual understanding of grasslands as non-erosive landscapes. Failure to acknowledge this will result in the noncompliance of surface waters to water quality standards.

    Objective The purpose of this study was to investigate the impact of specific behavioral problems on the health-related quality of life (HRQOL) in children and adolescents with epilepsy. Methods Children and adolescents with epilepsy (n=92; age range=6–17 years) and their mothers completed questionnaires about behavioral problems, HRQOL, socio-demographics, and epilepsy-related variables. To determine significant predictor variables of the HRQOL, the stepwise regression analyses and partial correlations were performed to adjust for other behavioral problems and covariates. Results The analyses revealed that an increase in social behavioral problems and delinquent behavior was associated with a decrease in the HRQOL. Lower levels of maternal education and the number of antiepileptic drugs were also associated with a decline in the HRQOL; the HRQOL and social behavioral problems remained significantly correlated after adjusting for maternal education level, number of antiepileptic drugs, and non-social behavioral problems. Conclusion Parents and practitioners should provide intervention if behavioral problems, particularly social behavioral problems, are observed in children or adolescents with epilepsy. PMID:27757126

    There is a potential for using waste tire rubber to make activated-carbon adsorbents for air-quality control applications. Such an approach provides a recycling path for waste tires and the production of new adsorbents from a low-cost waste material. Tire-derived activated carbons (TDACs) were prepared from waste tires. The resulting products are generally mesoporous, with N2-BET specific surface areas ranging from 239 to 1031 m2/g. TDACs were tested for their ability to store natural gas and remove organic compounds and mercury species from gas streams. TDACs are able to achieve 36% of the recommended adsorbed natural gas (methane) storage capacity for natural-gas-fueled vehicles. Equilibrium adsorption capacities for CH4 achieved by TDACs are comparable to Calgon BPL, a commercially available activated-carbon adsorbent. The acetone adsorption capacity for a TDAC is 67% of the adsorption capacity achieved by BPL at 1 vol % acetone. Adsorption capacities of mercury in simulated flue-gas streams are, in general, larger than adsorption capacities achieved by coal-derived activated carbons (CDACs) and BPL. Although TDACs may not perform as well as commercial adsorbents in some air pollution control applications, the potential lower cost of TDACS should be considered when evaluating economics.

    1975-01-01

    A study to determine the present enrichment status of Liopez Reservoir in San Luis Obispo county, California, and to evaluate copper sulfate algal treatment found that stratification in the reservoir regulates nutrient release and that algal control has been ineffective. Nuisance algal blooms, particularly from March to June, have been a problem in the warm multipurpose reservoir since it was initially filled following intense storms in 1968-69. The cyanophyte Anabaena unispora has been dominant; cospecies are the diatoms Stephanodiscus astraea and Cyclotella operculata, and the chlorophytes Pediastrum deplex and Sphaerocystis schroeteri. During an A. unispora bloom in May 1972 the total lake surface cell count was nearly 100,000 cells/ml. Thermal stratification from late spring through autumn results in oxygen deficiency in the hypolimnion and metalimnion caused by bacterial oxidation of organic detritus. The anaerobic conditions favor chemical reduction of organic matter, which constitute 10-14% of the sediment. As algae die, sink to the bottom, and decompose, nutrients are released to the hypolimnion , and with the autumn overturn are spread to the epilimnion. Algal blooms not only hamper recreation, but through depletion of dissolved oxygen in the epilimnion may have caused periodic fishkills. Copper sulfate mixed with sodium citrate and applied at 1.10-1.73 lbs/acre has not significantly reduced algal growth; a method for determining correct dosage is presented. (Lynch-Wisconsin)

    Detained girls bear high levels of criminal behavior and mental health problems that are likely to persist into young adulthood. Research with these girls began primarily from a risk management perspective, whereas a strength-based empowering perspective may increase knowledge that could improve rehabilitation. This study examines detained girls' quality of life (QoL) in relation to future mental health problems and offending, thereby testing the strength-based good lives model of offender rehabilitation (GLM). At baseline, 95 girls (Mage = 16.25) completed the World Health Organization QoL instrument to assess their QoL prior to detention in the domains of physical health, psychological health, social relationships, and environment. Six months after discharge, mental health problems and offending were assessed by self-report measures. Structural equation models were conducted to test GLM's proposed (in)direct pathways from QoL (via mental health problems) toward offending. Although we could not find support for GLM's direct negative pathway from QoL to offending, our findings did provide support for GLM's indirect negative pathway via mental health problems to future offending. In addition, we found a direct positive pathway from detained girls' satisfaction with their social relationships to offending after discharge. The current findings support the potential relevance of addressing detained girls' QoL, pursuing the development of new skills, and supporting them to build constructive social contacts. Our findings, however, also show that clinicians should not only focus on strengths but that detecting and modifying mental health problems in this vulnerable group is also warranted.

  11. The proxy problem anatomized: child-parent disagreement in health related quality of life reports of chronically ill adolescents

    2012-01-01

    Background Discrepancy between self-reports and parent-proxy reports of adolescent health-related quality of life (HRQoL) has been repeatedly acknowledged in the literature as the proxy problem. However, little is known about the extent and direction of this discrepancy. The purpose of this study is to explore to what extent and in what direction HRQoL self-reports of adolescents with chronic conditions and those of their parents differ. Methods A cross-sectional survey was conducted among adolescents suffering from chronic conditions and their parents. Socio-demographic and disease-related characteristics were collected and information about consequences of the chronic condition was assessed. HRQoL was measured with KIDSCREEN-10 and DISABKIDS condition generic measure (DCGM-10). Agreement was analysed through defining a threshold of agreement based on half of the standard deviation of the HRQoL score with the highest variance. Agreement occurred if the difference between adolescent and parent scores was less than or equal to half of the standard deviation. Intra-class correlation coefficients and Bland-Altman plots were also computed. The characteristics associated with direction of disagreement were statistically tested with one-way ANOVA and Chi-square tests. Results 584 paired HRQoL scores were obtained. Ratings from both adolescents and parents were high, compared to European norm data. Differences between adolescents and parents were statistically significant, yet relatively small. Disagreement existed in both directions: in 24.5% (KIDSCREEN-10) and 16.8% (DCGM-10) of the cases adolescents rated their HRQoL lower than did their parent, while in 32.2% (KIDSCREEN-10) and 31.7% (DCGM-10) of the cases the opposite was true. Adolescent's age, educational level and type of education, parent's educational level, number of hospital admissions and several other disease-related factors influenced direction of disagreement. Conclusions In a reasonable proportion of

    The problem of quality and quality assurance for the free exchange of blood and blood products in Europe is discussed. The background of all discussion of quality is the categorical theory of Aristoteles. The philosophical basis is described. The fundamental law of the daily work of a blood center has to be a philosophy of quality which depends on the sociodemographic situation in the region. This basic varies from country to country in Europe. The importance of the supranational bodies in Europe is mentioned. The weightness of the Code of Ethics is discussed. Virus safety, purity and validity of blood and blood products are described as parameters of the quality aspects. Finally it is confirmed that a well running blood program is a multicategorical problem.

    This paper reports on indoor air quality (IAQ) which has become a pervasive problem plaguing the building industry worldwide. Poor IAQ in commercial and office buildings is primarily related to new building technology, new materials and equipment and energy management operating systems. Occupants of buildings with air quality problems suffer from a common series of symptoms. As early as 1982, ASHRAE, realizing the significance of the problem, produced an IAQ position statement that identified strategies for solving IAQ problems. Many of those strategies have now been implemented, including Standard 62-1989, Ventilation for Acceptable Air Quality; Standard 90.1, Energy Efficient Design of New Buildings Except Low-Rise Residential Buildings; the 100 series of energy standards; and Guideline 1, Guideline for Commissioning of HVAC Systems.

    Children with sickle cell disease (SCD) are at risk for poor health-related quality of life (HRQOL). The current analysis sought to explore parent problem-solving abilities/skills as a moderator between SCD complications and HRQOL to evaluate applicability to pediatric SCD. At baseline, 83 children ages 6-12 years and their primary caregiver completed measures of child HRQOL. Primary caregivers also completed a measure of social problem-solving. A SCD complications score was computed from medical record review. Parent problem-solving abilities significantly moderated the association of SCD complications with child self-report psychosocial HRQOL (p = .006). SCD complications had a direct effect on parent proxy physical and psychosocial child HRQOL. Enhancing parent problem-solving abilities may be one approach to improve HRQOL for children with high SCD complications; however, modification of parent perceptions of HRQOL may require direct intervention to improve knowledge and skills involved in disease management.

    The current study examined the associations between child mental health problems and the quality of maternal and paternal parenting, and how these associations were moderated by three contextual factors: quality of parenting by the other parent, interparental conflict, and the number of overnights parents had with the child. Data for the current study came from a sample of divorcing families who are in high legal conflict over developing or maintaining a parenting plan following divorce. Analyses revealed that the associations between child mental health problems and positive maternal and paternal parenting were moderated by the quality of parenting provided by the other parent and by the number of overnights children spent with parents, but not by the level of interparental conflict. When parenting by the other parent and number of overnights were considered together in the same model, only number of overnights moderated the relations between parenting and child-behavior problems. The results support the proposition that the well-being of children in high-conflict divorcing families is better when they spend adequate time with at least one parent who provides high-quality parenting.

    The objectives of this study were (1) to illustrate the statistical problems encountered when comparing health-related quality of life (HRQL) measured by the Medical Outcome Study Short Form-36 (SF-36) in a diseased group to general population norms, and (2) to define age- and gender-standardized dichotomous indicator variables for each health concept and show that these indicator variables facilitate comparisons between the diseased sample and the general population. Our "diseased" group consisted of 136 sequentially consenting patients referred to the syncope clinic for assessment and treatment. Participants completed the SF-36 questionnaire before undergoing diagnostic testing. General population norms for the SF-36 are available from the responses of 2474 participants in the National Survey of Functional Health Status, conducted in 1990 in the United States. Comparison of the SF-36 in a diseased sample with general population norms is difficult, owing to skewed and unusual distributions in both groups. In addition, making comparisons within age and gender strata is difficult if the within strata sample size is small. We propose a dichotomous indicator variable for each health concept that classifies an individual as having impaired health if he or she scored lower than the 25th percentile for the appropriate age and gender general population strata. By definition, the prevalence of impaired health in the general population is 25% for all eight health concepts. Comparison between the eight health-concept variables is easy because the population norm is the same for each of them. These indicator variables are age and gender adjusted, so that even if the sample did not have the age and gender distribution as the general population, comparisons can still be made with the value of 25.

    There are many methods proposed for inferring parameters of the Ising model from given data, that is a set of configurations generated according to the model itself. However little attention has been paid until now to the data, e.g. how the data is generated, whether the inference error using one set of data could be smaller than using another set of data, etc. In this paper we discuss the data quality problem in the inverse Ising problem, using as a benchmark the kinetic Ising model. We quantify the quality of data using effective rank of the correlation matrix, and show that data gathered in a out-of-equilibrium regime has a better quality than data gathered in equilibrium for coupling reconstruction. We also propose a matrix-perturbation based method for tuning the quality of given data and for removing bad-quality (i.e. redundant) configurations from data.

    Background A proportion of people with mental health problems require longer term care in a psychiatric or social care institution. However, there are no internationally agreed quality standards for institutional care and no method to assess common care standards across countries. We aimed to identify the key components of institutional care for people with longer term mental health problems and the effectiveness of these components. Methods We undertook a systematic review of the literature using comprehensive search terms in 11 electronic databases and identified 12,182 titles. We viewed 550 abstracts, reviewed 223 papers and included 110 of these. A "critical interpretative synthesis" of the evidence was used to identify domains of institutional care that are key to service users' recovery. Results We identified eight domains of institutional care that were key to service users' recovery: living conditions; interventions for schizophrenia; physical health; restraint and seclusion; staff training and support; therapeutic relationship; autonomy and service user involvement; and clinical governance. Evidence was strongest for specific interventions for the treatment of schizophrenia (family psychoeducation, cognitive behavioural therapy (CBT) and vocational rehabilitation). Conclusion Institutions should, ideally, be community based, operate a flexible regime, maintain a low density of residents and maximise residents' privacy. For service users with a diagnosis of schizophrenia, specific interventions (CBT, family interventions involving psychoeducation, and supported employment) should be provided through integrated programmes. Restraint and seclusion should be avoided wherever possible and staff should have adequate training in de-escalation techniques. Regular staff supervision should be provided and this should support service user involvement in decision making and positive therapeutic relationships between staff and service users. There should be clear lines

    Dominance relations commonly are used to prune unnecessary nodes in search graphs, but they are problem-dependent and cannot be derived by a general procedure. The authors identify machine learning of dominance relations and the applicable learning mechanisms. A study of learning dominance relations using learning by experimentation is described. This system has been able to learn dominance relations for the 0/1-knapsack problem, an inventory problem, the reliability-by-replication problem, the two-machine flow shop problem, a number of single-machine scheduling problems, and a two-machine scheduling problem. It is considered that the same methodology can be extended to learn dominance relations in general.

    Background Cancer survivors treated with hematopoietic stem cell transplant rely on their social network for successful recovery. However, some survivors have negative attitudes about using social resources (negative social network orientation) that are critical for their recovery. Purpose We examined the association between survivors’ social network orientation and health-related quality of life (HRQoL) and whether it was mediated by social resources (network size, perceived support, and negative and positive support-related social exchanges). Methods In a longitudinal study, 255 survivors completed validated measures of social network orientation, HRQoL, and social resources. Hypotheses were tested using path analysis. Results More negative social network orientation predicted worse HRQoL (p < .001). This association was partially mediated by lower perceived support and more negative social exchanges. Conclusions Survivors with negative social network orientation may have poorer HRQoL in part due to deficits in several key social resources. Findings highlight a subgroup at risk for poor transplant outcomes and can guide intervention development. PMID:26693932

    The study was aimed to verify, from a longitudinal perspective, whether perceived peer support would mediate the relationship between attachment and internalizing problems. Longitudinal participants included 482 adolescents (245 boys) aged 14-15 years in Wave 1 and 17-18 years in Wave 2. Participants in Wave 1 completed the Relationship Questionnaire, and those in Wave 2 completed the Social Support Questionnaire and the Youth Self-Report. Results showed that secure attachment positively predicted high levels of perceived peer support and negatively predicted internalizing problems, whereas fearful and preoccupied attachment negatively predicted perceived peer support and positively predicted internalizing problems. The mediation models showed that perceived peer support partially mediated the relationship between secure attachment and internalizing problems as well as between preoccupied attachment and internalizing problems and between fearful attachment and internalizing problems. Our results confirm the role of subjective perception of peer support in contributing to the prediction of internalizing problems beyond attachment styles.

    2011-01-01

    This report summarizes the analyses and results produced by a five-member investigative team of Government, university, and industry experts, established by NASA HQ. The team examined data quality problems associated with high performance liquid chromatography (HPLC) analyses of pigment concentrations in seawater samples produced by the San Diego State University (SDSU) Center for Hydro-Optics and Remote Sensing (CHORS). This report shows CHORS did not validate the methods used before placing them into service to analyze field samples for NASA principal investigators (PIs), even though the HPLC literature contained easily accessible method validation procedures, and the importance of implementing them, more than a decade ago. In addition, there were so many sources of significant variance in the CHORS methodologies, that the HPLC system rarely operated within performance criteria capable of producing the requisite data quality. It is the recommendation of the investigative team to a) not correct the data, b) make all the data that was temporarily sequestered available for scientific use, and c) label the affected data with an appropriate warning, e.g., "These data are not validated and should not be used as the sole basis for a scientific result, conclusion, or hypothesis--independent corroborating evidence is required."

    This article presents the results of a transboundary water quality monitoring program at the two Nogales area in the Arizona-Sonora border region. The program was carried out jointly in 1990 by U.S. and Mexican institutions. The results show pollution problems due to deficiencies in Nogales, Sonora municipal sewerage system, causing not only sewage spills in several parts of the city but also creating occasional transboundary problems. The results also showed potential illegal dumping of industrial hazardous waste (VOCs) into Nogales' municipal sewerage system. All of the organic compounds found in the sewage samples are solvents frequently used by the border industry. Occasional brakes of pipes spill the pollutants into the Nogales Wash, a water stream that runs parallel to Nogales' main sewerage line. Samples of the municipal water system showed no traces of pollutants. However, two rounds of samples detected concentrations of VOCs in wells used to supply water by trucks to low income neighborhoods in Nogales, Sonora. Ironically, the pollution detected in these wells has a greater impact in low income groups of the city that pay three to four times more per liter of water they consume, than the rest of the inhabitants with clean water from the municipal system.

The results also showed potential illegal dumping of industrial hazardous waste (VOCs) into Nogales' municipal sewerage system. All of the organic compounds found in the sewage samples are solvents frequently used by the border industry. Occasional brakes of pipes spill the pollutants into the Nogales Wash, a water stream that runs parallel to Nogales' main sewerage line. Samples of the municipal water system showed no traces of pollutants. However, two rounds of samples detected concentrations of VOCs in wells used to supply water by trucks to low income neighborhoods in Nogales, Sonora. Ironically, the pollution detected in these wells has a greater impact in low income groups of the city that pay three to four times more per liter of water they consume, than the rest of the inhabitants with clean water from the municipal system.

    This issue presents the conclusive results of two European Commission funded Projects, namely Universal Microarrays for the Evaluation of Fresh-water Quality Based on Detection of Pathogens and their Toxins (MicroAQUA) and Rationally Designed Aquatic Receptors (RADAR). These projects focused their activities on the quality of drinking water as an extremely important factor for public health of humans and animals. The MicroAQUA Project aimed at developing a universal microarray chip for the detection of various pathogens (cyanobacteria, bacteria, viruses and parasitic protozoa) and their toxins in waters. In addition, the project included the detection of select species of diatoms, which represent reliable bio-indicators to assess overall water quality. Large numbers of compounds are released into the environment; some of these are toxins such as endocrine disrupting compounds (EDCs) and can affect the endocrine, immune and nervous systems of a wide range of animals causing alterations such as reproductive disorders and cancer. Detection of these contaminants in water systems is important to protect sensitive environmental sites and reduce the risk of toxins entering the food chain. A modular platform for monitoring toxins in water and food production facilities, using biosensors derived from aquatic organisms, was the main goal of RADAR Project.

    This study examined the quality of the research base related to strategy instruction priming the underlying mathematical problem structure for students with learning disabilities and those at risk for mathematics difficulties. We evaluated the quality of methodological rigor of 18 group research studies using the criteria proposed by Gersten et al. and 10 single case design (SCD) research studies using criteria suggested by Horner et al. and the What Works Clearinghouse. Results indicated that 14 group design studies met the criteria for high-quality or acceptable research, whereas SCD studies did not meet the standards for an evidence-based practice. Based on these findings, strategy instruction priming the mathematics problem structure is considered an evidence-based practice using only group design methodological criteria. Implications for future research and for practice are discussed.

    Two general problems related to resistive magnetohydrodynamic stability are addressed in this paper. First, a general stability condition previously derived by the author for a class of real systems, occurring especially in plasma physics, is proved to persist to second order, despite the addition of several antisymmetric operators of first order in the linearized stability equation. Second, for a special but representative choice of the stability operators, a nonperturbative analysis demonstrates the existence of a critical density for the appearance of an overstability and the connected Hopf bifurcation, as suggested in a previous paper [Phys. Lett. A [bold 180], 257 (1993)].

    We consider the behavior of macroscopic bodies within the framework of relative locality [G. Amelino-Camelia, L. Freidel, J. Kowalski-Glikman, and L. Smolin, arXiv:1101.0931]. This is a recent proposal for Planck scale modifications of the relativistic dynamics of particles which are described as arising from deformations in the geometry of momentum space. We consider and resolve a common objection against such proposals, which is that, even if the corrections are small for elementary particles in current experiments, they are huge when applied to composite systems such as soccer balls, planets, and stars, with energies E{sub macro} much larger than M{sub P}. We show that this soccer ball problem does not arise within the framework of relative locality because the nonlinear effects for the dynamics of a composite system with N elementary particles appear at most of order E{sub macro}/N{center_dot}M{sub P}.

  2. Operational Water Quality Management: Problem Context and Evaluation of a Model for River Quality

    NASA Astrophysics Data System (ADS)

    Beck, M. B.; Finney, B. A.

    1987-11-01

    In river basins where water is used intensively and by many activities and facilities, the essential questions of water quality management are changing from being issues of planning alone to being problems of operational decision making. In the past 10 years in the United Kingdom, for example, the technology, economics, legislation, and institutional structure of management have all changed substantially. Together these changes have overturned the traditional assumptions made about the nature of managing river water quality. This paper discusses the foundations for a case study in operational water quality management. The basis of the case study is a dynamic model for stream discharge and quality covering a 54-km stretch of the Bedford Ouse River in England. The model describes interactions among biochemical oxygen demand, dissolved oxygen, ammonium N, nitrate N, and chlorophyll a concentrations at various points along the river; preliminary identification results are presented using daily time series data for the whole of 1974. The behavior of the river, which relates the effects of a major upstream discharger to a downstream abstractor, is dominated by the dynamics of algal population growth and mortality. In addition to the presentation of these results the paper sets out the technical, economic, and policy questions central to the practical feasibility and potential of operational water quality management. This includes questions in quantifying the stochastic, dynamic aspects of river basin management, the development of improved operating strategies, and the development of operational decision support systems.

    1987-12-01

    A study was made of health problems reported by data entry clerks working in two large data pools within the Québec Public Service Administration. In order to collect the data, 350 clerks answered a questionnaire, representing a return rate of 92%. The results indicate that, in comparison with women in other occupations, the data entry clerks have a high rate of occurrence of psychiatric symptoms (measured by the Ilfeld index) as well as a high degree of use of over-the-counter and prescription drugs. In addition, these two problems are more prevalent in full-time clerks than in part-time clerks. The psychiatric symptoms appear related to the combined influence of two main factors: work overload and the monotony of work specialization. A third factor, the quality of the relationships among workers in the pool, also seemed to affect the regular full-time clerks. PMID:2892901

    Issues and problems related to the needs for quantity and quality in health care have been presented. The need for quantity has been quite successfully addressed in the last 20 years. Better quality of health care is very much in the minds of policy makers, providers and the informed public. Quality assessment and assurance as a programmed and on-going process in individual hospitals is systematically promoted and developed. An accreditation system for hospitals is planned for the future. This paper has not been able to contribute anything of value to the current practice of quality assurance. The industrialized world has passed the stages Indonesia is now going through. To some Australian colleagues, this presentation perhaps has revealed that one of their closest neighbours is struggling hard to improve the quality of life of its people, despite the tremendous problems and constraints with which it is confronted. Australia has always provided a helping hand in this struggle.

    Students with learning difficulties participated in two studies that analyzed the effects of problem difficulty and reinforcer quality upon time allocated to two sets of arithmetic problems reinforced according to a concurrent variable-interval 30-s variable-interval 120-s schedule. In Study 1, high- and low-difficulty arithmetic problems were systematically combined with rich and lean concurrent schedules (nickels used as reinforcers) across conditions using a single-subject design. The pairing of the high-difficulty problems with the richer schedule failed to offset time allocated to that alternative. Study 2 investigated the interactive effects of problem difficulty and reinforcer quality (nickels vs. program money) upon time allocation to arithmetic problems maintained by the concurrent schedules of reinforcement. Unlike problem difficulty, the pairing of the lesser quality reinforcer (program money) with the richer schedule reduced the time allocated to that alternative. The magnitude of this effect was greatest when combined with the low-difficulty problems. These studies have important implications for a matching law analysis of asymmetrical reinforcement variables that influence time allocation. PMID:8881341

  8. Metal cladding envelope problems, retrofit solutions, and quality control investigations

    NASA Astrophysics Data System (ADS)

    Colantonio, Antonio

    1992-04-01

    This paper deals with a case study of a building envelope retrofit of an insulated sheet steel and corrugated metal clad building. The building in discussion is a satellite testing facility which requires specific clean room conditions with controlled interior temperature (22 degree(s)C +/- 1 degree(s)C) and high relative humidity conditions (45% +/- 3%) to facilitate satellite testing programs. Preliminary mechanical system inspections indicated substantial increase in air intake to make up for air leakage losses. An infrared inspection along with an approximate air leakage test of the building envelope was requested by the client to determine the magnitude of the building envelope problem. This investigation concluded that significant air leakage was present throughout the building envelope and that existing mechanical systems did not have sufficient capacity to pressurize the building and negate wind and stack effect. Exfiltration particularly through openings on the top sections of the building were causing interior moisture to saturate wall insulation and render it ineffective. Concern for rusting of metal components was indicated. The subsequent envelope analysis discovered a number of typical metal building details that led to poor air tightness and wall insulation ineffectiveness. These were correlated to infrared investigation data. The retrofit solutions produced for this building not only apply to this building but to other similar building types. Further investigations indicated that air leakage and mechanical system performance were significant problems with buildings using metal cladding systems comparable to this building. Quality control before, during and after construction was identified as an important function of the architectural commissioning of the retrofit work and infrared investigations were used to verify locations of air leakage and insulation effectiveness.

    Objective: To identify the level of depression, the level of life quality, and the relationship between these, in patients applying to sleep centers for various sleep problems. Methods: This cross-sectional study included 229 patients who applied for polysomnography at sleeping centers under supervision of the Neurology and Chest Diseases Clinics of Kayseri Education and Research Hospital, Kayseri, Turkey between June and August 2013. The data collection tools were a socio-demographical data form, Beck Depression Inventory (BDI), Pittsburgh Sleep Quality Index (PSQI), and the World Health Organization Quality of Life Scale (WHOQOL-BREF). For statistical analyses, the Student t-test, Kruskal-Wallis-variant analysis, and chi-square tests were used. Significance level was considered as p<0.05. Results: In our study, patients who were older aged, married, not working, and who had a chronic disease, and a severe depressive symptom were observed to have significantly poorer sleep quality. While patients with any chronic disease had significantly higher scores for total PSQI and depression, their physical, mental, and social WHOQOL-BREF scores were significantly lower. The PSQI total scores, and depression scores of the smoking patients were significantly higher for physical, mental, and social WHOQOL-BREF fields. There was a positive correlation between PSQI scores and BDI scores while there was a negative correlation among BDI, PSQI, and WHOQOL-BREF life quality sub-scale scores. Conclusions: Sleep quality was significantly poorer in patients who were older aged, married, not working, and who had a chronic disease, and a severe depressive symptom. There was a significantly negative correlation among depression, sleep quality, and life quality, while there was a significantly positive correlation between life quality and depression.

    PubMed

    2015-01-01

    Neurodegenerative disorders are characterized by decreased regional cerebral blood flow. Supporting this concept, both cognitive training exercises and physical activity promote blood flow increase and correlate with healthy cognitive aging. The terminal branches of the posterior circulation supply blood to areas of the brain, such as the thalamus, hippocampus, occipital lobe, and cerebellum, involved with important intellectual functions, particularly recent memory, visual-spatial functioning, and visuomotor adaptations. Amnesia and visual agnosia may be a complication of not only posterior circulation infarctions but also vertebrobasilar insufficiency (VBI) without accompanying structural infarcts. The cognitive impairment maybe a manifestation of transient attacks and may persist beyond resolution of symptoms related to ischemia. Early recognition of cognitive deficits in the VBI patient is important because several recent reports show stent placements or medical treatment may improve cognition. PMID:26738337

    Aims and objectives: The purpose of this study was to examine the sleep quality and health-related quality of life (HRQOL) in patients after renal transplantation and to explore the relationship between the quality of sleep and the HRQOL. Background: Sleep disorders are still an important clinical problem after renal transplantation. Previous studies mainly focused on patients’ sleep quality before kidney transplant. More studies are needed to document sleep quality after renal transplantation. Design: A cross-sectional design was used in this study. Methods: A convenience sample of renal transplant recipients was recruited at an outpatient transplant clinic of a general hospital in Beijing, China. The Pittsburgh Sleep Quality Index (PSQI) was used to measure quality of sleep. The Medical Outcomes Study 36-item Short Form (MOS SF-36) was used to measure health-related quality of life. Results: The average PSQI score of the 204 renal transplant recipients was 5.81±3.52, significantly lower than the norm. Fifty (24.5%) recipients were classified as having poor sleep quality (global PSQI > 7). The mean scores of renal transplant recipients for SF-36 Mental Component Summary (MCS) and Physical Component Summary (PCS) were 47.57±6.71 and 48.26±9.66 respectively. Compared with residents in Sichuan province, recipients’ scores for SF-36 dimensions were statistically lower except the dimension of mental health. SF-36 scores of poor sleepers (PSQI > 7) were significantly lower than the good sleepers (PSQI ≤ 7) in both the MCS and PCS. Significant differences exist between the groups in physical function, bodily pain, vitality, and mental health dimensions. Conclusions: Sleep quality and HRQOL of patients after renal transplantation were lower than the norm. Poor sleep is associated with lower HRQOL. Relevance to clinical practice: Health professionals need to pay attention to sleep quality and HRQOL in renal transplant recipients and take appropriate measures to

    We describe an original low cost hardware setting for efficient testing of stereo vision algorithms. The method uses a combination of a special hardware setup and mathematical model and is easy to construct, precise in applications of our interest. For a known scene we derive its analytical representation, called virtual scene. Using a four point correspondence between the scene and virtual one we compute extrinsic camera parameters, and project virtual scene on the image plane, which is the ground truth for depth map. Another result, presented in this paper, is a new depth map quality metric. Its main purpose is to tune stereo algorithms for particular problem, e.g. obstacle avoidance.

    The challenge of producing training programs that lead to quality learning outcomes is ever present in aviation, especially when economic and regulatory pressures are brought into the equation. Previous research by Telfer & Moore (1997) indicates the importance of appropriate alignment of beliefs about learning across all levels of an organization from the managerial level, through the instructor/check and training level, to the pilots and other crew. This paper argues for a central focus on approaches to learning and training that encourage understanding, problem solving and application. Recent research in the area is emphasized as are methods and techniques for enhancing deeper learning.

    2013-01-01

    Obesity and other eating-related problems are widespread and are associated with harmful physical, psychological, and social problems. The dramatic increases in rates of pediatric obesity has created a mounting need for psychologists and other mental health care providers to play a significant role in the assessment and treatment of youth with eating- and weight-related problems. Therefore, it is imperative for providers to be aware of the causes and consequences of eating- and weight-related problems and to be familiar with evidence-based assessment and intervention approaches. Currently, the most well-established intervention approaches are family-based behavioral treatments, and weight loss maintenance treatments with a socio-ecological focus are promising. This paper provides a comprehensive review of these topics and highlights the important roles that mental health care providers can have. Medical settings are often the patient’s first point of contact within the healthcare system, making mental health care providers in such settings uniquely suited to assess for a broad range of eating- and weight-related problems and associated comorbidities, to deliver relevant evidence-based interventions, and to make appropriate referrals. Moving forward, providers and researchers must work together to address key questions related to the nature of eating- and weight-related problems in youth and to achieve breakthroughs in the prevention and treatment of such problems in this vulnerable population.

    Alvarez-Vázquez, Lino J.; Fernández, Francisco J.; Muñoz-Sola, Rafael

    This paper is concerned with an optimal control problem related to the determination of an optimal profile for the steam temperature into the autoclave along the processing of canned foods. The problem studies a system coupling the evolution Navier-Stokes equations with the heat transfer equation by natural convection (the so-called Boussinesq equations), and with the microorganisms removal equation. The essential difficulties in the study of this multistate control problem arise from the lack of uniqueness for the solution of the state system. Here we obtain—after a careful analysis of the problem mathematical formulation—the uniqueness of part of the state, and the existence of optimal solutions.

    Tam, Christopher K. W.; Aganin, Alexei

    2000-01-01

    The transonic nozzle transmission problem and the open rotor noise radiation problem are solved computationally. Both are multiple length scales problems. For efficient and accurate numerical simulation, the multiple-size-mesh multiple-time-step Dispersion-Relation-Preserving scheme is used to calculate the time periodic solution. To ensure an accurate solution, high quality numerical boundary conditions are also needed. For the nozzle problem, a set of nonhomogeneous, outflow boundary conditions are required. The nonhomogeneous boundary conditions not only generate the incoming sound waves but also, at the same time, allow the reflected acoustic waves and entropy waves, if present, to exit the computation domain without reflection. For the open rotor problem, there is an apparent singularity at the axis of rotation. An analytic extension approach is developed to provide a high quality axis boundary treatment.

    The influence of early relational experience on later social understanding has evoked rich theoretical discussion but relatively little empirical inquiry. Enlisting data from the NICHD Study of Early Child Care and Youth Development, measures of the security of attachment in infancy, toddlerhood, and early childhood, together with measures of parenting quality (maternal sensitivity and depressive symptoms) gathered longitudinally throughout infancy and early childhood, were used to predict differences in children's thoughts and feelings about peers (i.e., social problem solving, negative attributional biases, aggressive solutions to ambiguous social situations, and self-reported loneliness) when children were 54 months and in first grade. Relational experiences, especially before 36 months, were significantly predictive of later peer-related representations. Attachment security at 24 and 36 months was associated with enhanced social problem-solving skills and less loneliness, but security of attachment at 15 months was nonpredictive. Early maternal sensitivity was positively associated with later social problem-solving and negatively with aggressive responses, and early maternal depressive symptoms were positively associated with children's negative attributions. Concurrent parenting quality was also associated with children's thoughts and feelings about peers, but less consistently. These findings shed new light on how early relational experiences may contribute to social information processing with peers at the end of the preschool years, and that the timing of relational influences may be crucial.

  9. Extraction of a group-pair relation: problem-solving relation from web-board documents.

    2016-01-01

    This paper aims to extract a group-pair relation as a Problem-Solving relation, for example a DiseaseSymptom-Treatment relation and a CarProblem-Repair relation, between two event-explanation groups, a problem-concept group as a symptom/CarProblem-concept group and a solving-concept group as a treatment-concept/repair concept group from hospital-web-board and car-repair-guru-web-board documents. The Problem-Solving relation (particularly Symptom-Treatment relation) including the graphical representation benefits non-professional persons by supporting knowledge of primarily solving problems. The research contains three problems: how to identify an EDU (an Elementary Discourse Unit, which is a simple sentence) with the event concept of either a problem or a solution; how to determine a problem-concept EDU boundary and a solving-concept EDU boundary as two event-explanation groups, and how to determine the Problem-Solving relation between these two event-explanation groups. Therefore, we apply word co-occurrence to identify a problem-concept EDU and a solving-concept EDU, and machine-learning techniques to solve a problem-concept EDU boundary and a solving-concept EDU boundary. We propose using k-mean and Naïve Bayes to determine the Problem-Solving relation between the two event-explanation groups involved with clustering features. In contrast to previous works, the proposed approach enables group-pair relation extraction with high accuracy.

    Anxiety disorders constitute the most common mental health disturbance experienced by youth. Sleep-related problems (SRPs) are highly prevalent among anxious youth and encompass a variety of problems including nighttime fears, insomnia, and refusal to sleep alone. Given that chronic sleep disturbance is associated with a range of behavioral and physical problems in youth and predicts future psychopathology, it is important to elucidate the nature of SRPs in anxious youth. The present study investigated the relationship between sleep problems and anxiety sensitivity in a sample of 101 anxious youth, ages 6-17. Heightened anxiety sensitivity significantly predicted prolonged sleep onset latency across the sample, even after accounting for severity of anxiety, depression, and age. Results support previous research indicating that SRPs are common among anxious youth and suggest that anxiety sensitivity may play a particularly important role in sleep onset latency.

  13. Quality analysis of the solution produced by dissection algorithms applied to the traveling salesman problem

    The aim of this paper is to analyze experimentally the quality of the solution obtained with dissection algorithms applied to the geometric Traveling Salesman Problem. Starting from Karp`s results. We apply a divide and conquer strategy, first dividing the plane into subregions where we calculate optimal subtours and then merging these subtours to obtain the final tour. The analysis is restricted to problem instances where points are uniformly distributed in the unit square. For relatively small sets of cities we analyze the quality of the solution by calculating the length of the optimal tour and by comparing it with our approximate solution. When the problem instance is too large we perform an asymptotical analysis estimating the length of the optimal tour. We apply the same dissection strategy also to classical heuristics by calculating approximate subtours and by comparing the results with the average quality of the heuristic. Our main result is the estimate of the rate of convergence of the approximate solution to the optimal solution as a function of the number of dissection steps, of the criterion used for the plane division and of the quality of the subtours. We have implemented our programs on MUSIC (MUlti Signal processor system with Intelligent Communication), a Single-Program-Multiple-Data parallel computer with distributed memory developed at the ETH Zurich.

  14. Science and technology related global problems: An international survey of science educators

    Bybee, Rodger W.; Mau, Teri

    This survey evaluated one aspect of the Science-Technology-Society theme, namely, the teaching of global problems related to science and technology. The survey was conducted during spring 1984. Two hundred sixty-two science educators representing 41 countries completed the survey. Response was 80%. Findings included a ranking of twelve global problems (the top six were: World Hunger and Food Resources, Population Growth, Air Quality and Atmosphere, Water Resources, War Technology, and Human Health and Disease). Science educators generally indicated the following: the science and technology related global problems would be worse by the year 2000; they were slightly or moderately knowledgeable about the problems; print, audio-visual media, and personal experiences were their primary sources of information; it is important to study global problems in schools; emphasis on global problems should increase with age/grade level; an integrated approach should be used to teach about global problems; courses including global problems should be required of all students; most countries are in the early stages of developing programs including global problems; there is a clear trend toward S-T-S; there is public support for including global problems; and, the most significant limitations to implementation of the S-T-S theme (in order of significance) are political, personnel, social, psychological, economic, pedagogical, and physical. Implications for research and development in science education are discussed.

    Global terrorist activities have increased significantly over the past decade. The impact of terrorism-related trauma on the health of individuals in low- and middle-income countries is under-reported. Trauma management in African countries in particular is uncoordinated, with little or no infrastructure to cater for emergency surgical needs. This article highlights the need for education, training and research to mitigate the problems related to terrorism and surgical public health.

  19. The Japanese society of alcohol-related problems.

    PubMed

    Maruyama, Katsuya; Higuchi, Susumu

    2004-04-01

    This paper presents an outline of the Japanese Society of Alcohol-Related Problems. The precursor of the Society was the Japan Alcoholism Treatment Research Group, inaugurated in 1979, by merging two local research groups in the Tokyo and Osaka areas, both of which were exclusive gatherings of psychiatrists associated with alcoholism clinics. The Research Group developed into the Society in 1992, as the number of participants including those from other medical professions increased yearly, and the subjects of the group widened to include all addictive behaviours. In reflecting the process of establishment, it is unique in many aspects as a scientific society. The Society is not a science-orientated body for presentation of new research findings. The main programme of the annual meeting is therefore a set of symposia in which members participate and discuss clinical and/or social problems arising from dependency on alcohol or drugs. Perhaps because of its content, the annual meeting is attended each year by the largest number of participants among all the societies in Japan concerned with alcohol and drugs. For the next several years, the Society's activities will be directed at (1) establishment of guidelines for early identification of and intervention in alcohol-related problems; (2) expansion of its membership to include those in related fields of medicine and non-medical professions; (3) improvement of the system of journal publication; and (4) creation of a system for timely adequate response to social problems associated with drugs and alcohol.

    2013-01-01

    OBJECTIVE: This study used prospective data to test the hypothesis that exposure to alcohol advertising contributes to an increase in underage drinking and that an increase in underage drinking then leads to problems associated with drinking alcohol. METHODS: A total of 3890 students were surveyed once per year across 4 years from the 7th through the 10th grades. Assessments included several measures of exposure to alcohol advertising, alcohol use, problems related to alcohol use, and a range of covariates, such as age, drinking by peers, drinking by close adults, playing sports, general TV watching, acculturation, parents’ jobs, and parents’ education. RESULTS: Structural equation modeling of alcohol consumption showed that exposure to alcohol ads and/or liking of those ads in seventh grade were predictive of the latent growth factors for alcohol use (past 30 days and past 6 months) after controlling for covariates. In addition, there was a significant total effect for boys and a significant mediated effect for girls of exposure to alcohol ads and liking of those ads in 7th grade through latent growth factors for alcohol use on alcohol-related problems in 10th grade. CONCLUSIONS: Younger adolescents appear to be susceptible to the persuasive messages contained in alcohol commercials broadcast on TV, which sometimes results in a positive affective reaction to the ads. Alcohol ad exposure and the affective reaction to those ads influence some youth to drink more and experience drinking-related problems later in adolescence. PMID:23359585

    2015-01-01

    Although sociodemographic factors are one aspect of understanding the effects of neighborhood environments on health, equating neighborhood quality with socioeconomic status ignores the important role of physical neighborhood attributes. Prior work on neighborhood environments and health has relied primarily on level of socioeconomic disadvantage as the indicator of neighborhood quality without attention to physical neighborhood quality. A small but increasing number of studies have assessed neighborhood physical characteristics. Findings generally indicate that there is an association between living in deprived neighborhoods and poor health outcomes, but rigorous evidence linking specific physical neighborhood attributes to particular health outcomes is lacking. This paper discusses the methodological challenges and limitations of measuring physical neighborhood environments relevant to health and concludes with proposed directions for future work.

    Two sources of information (parent reported sleep diaries and actigraph records) were used to investigate how toddler sleep characteristics (bed time/sleep onset, wake time/sleep offset, total nighttime sleep and total sleep time) are related to sleep problems and temperament. There were 64 toddler participants in the study. Consistent with studies of older children, parent reports differed from actigraph based records. The findings that parent reported and actigraph recorded sleep characteristics varied as a function of parent report of toddler sleep problems and temperament add needed information on toddler sleep. Such information may contribute to improving parents’ awareness of their child’s sleep characteristics and correlates of problem sleep. PMID:26151612

    Posttraumatic stress disorder (PTSD) represents a debilitating psychiatric condition that is affecting the lives of many returning veterans. PTSD and alcohol use and dependence are highly comorbid. The purpose of this study was to understand the functional mechanisms between PTSD and alcohol use and problems. Specifically, the role of negative urgency and emotional intelligence were investigated as vulnerability and resiliency factors, respectively. This study utilized experience sampling to test associations between PTSD symptoms and alcohol use and related problems in a sample of 90 OIF/OEF veterans. Participants completed eight brief questionnaires daily for two weeks on palmtop computers. Elevations in PTSD symptoms during the day were associated with subsequent increases in alcohol use and associated problems that night. PTSD symptoms were associated with greater problems above and beyond the effect of drinking level at both the within- and between- person level. Emotional intelligence was associated with lower negative urgency, fewer PTSD symptoms, and less alcohol use and associated problems. The effects of emotional intelligence were primarily indirect via negative urgency and the effects of negative urgency on alcohol use and problems were indirect via its positive association with PTSD symptoms. Hypothesized cross-level effects of emotional intelligence and negative urgency were not supported. The findings suggest a functional association between PTSD symptoms and alcohol consumption. The association between PTSD symptoms and alcohol consumption is consistent with a self-medication model. However, the significant associations between PTSD symptoms and alcohol problems, after controlling for use level, suggest a broader role of dysregulation. PMID:25134021

    GEE-WIS scientific problem solving consists of observing, hypothesizing, synthesis, argument building and reasoning, in the context of analysis, representation, modeling and sense-making of real-time authentic water quality data. Geoscience Environmental Education - Web-accessible Instrumented Systems, or GEE-WIS, an NSF Geoscience Education grant, has established a set of companion websites that stream real-time data from two campus retention ponds for research and use in secondary and undergraduate water quality lessons. We have targeted scientific problem solving skills because of the nature of the GEE-WIS environment, but further because they are central to state and federal efforts to establish science education curriculum standards and are at the core of performance-based testing. We have used a design experiment process to create and test two Anchored Instruction scenario problems. Customization such as that done through a design process, is acknowledged to be a fundamental component of educational research from an ecological psychology perspective. Our efforts have shared core design elements with other NSF water quality projects. Our method involves the analysis of student written scenario responses for level of scientific problem solving using a qualitative scoring rubric designed from participation in a related NSF project, SCALE (Synergy Communities: Aggregating Learning about Education). Student solutions of GEE-WIS anchor problems from Fall 2001 and Spring 2002 will be summarized. Implications are drawn for those interested in making secondary and high education geoscience more realistic and more motivating for students through the use of real-time authentic data via Internet.

    Researchers have found that, compared to European Americans, African Americans report later initiation of drinking, lower rates of use, and lower levels of use across almost all age groups. Nevertheless, African Americans also have higher levels of alcohol problems than European Americans. After reviewing current data regarding these trends, we provide a theory to understand this apparent paradox as well as to understand variability in risk among African Americans. Certain factors appear to operate as both protective factors against heavy use and risk factors for negative consequences from use. For example, African American culture is characterized by norms against heavy alcohol use or intoxication, which protects against heavy use but also provides within-group social disapproval when use does occur. African Americans are more likely to encounter legal problems from drinking than European Americans, even at the same levels of consumption, perhaps thus resulting in reduced consumption but more problems from consumption. There appears to be one particular group of African Americans, low-income African American men, who are at the highest risk for alcoholism and related problems. We theorize that this effect is due to the complex interaction of residential discrimination, racism, age of drinking, and lack of available standard life reinforcers (e.g., stable employment and financial stability). Further empirical research will be needed to test our theories and otherwise move this important field forward. A focus on within-group variation in drinking patterns and problems is necessary. We suggest several new avenues of inquiry. PMID:23477449

    Eades, J. B., Jr.; Wolf, H.

    1972-01-01

    Selected problems dealing with orbiting tethered body systems have been studied. In addition, a relative motion orbit determination program was developed. Results from these tasks are described and discussed. The expected tethered body motions were examined, analytically, to ascertain what influence would be played by the physical parameters of the tether, the gravity gradient and orbit eccentricity. After separating the motion modes these influences were determined; and, subsequently, the effects of oscillations and/or rotations, on tether force, were described. A study was undertaken, by examining tether motions, to see what type of control actions would be needed to accurately place a mass particle at a prescribed position relative to a main vehicle. Other applications for tethers were studied. Principally these were concerned with the producing of low-level gee forces by means of stabilized tether configurations; and, the initiation of free transfer trajectories from tether supported vehicle relative positions.

    This study aimed to assess childhood bruxism relating associated factors and the bruxism's impact on oral health-related quality of life (OHRQoL). A case-control study was performed with 3- to 6-year-old children obtained from public preschools in Brazil. The case and control groups had 21 and 40 children, respectively. Associations between bruxism and respiratory problems (p = 0.04, OR: 0.33, CI: 0.09 to 1.14), dental wear (p < 0.01, OR: 0.01, CI: 0.00 to 0.05), malocclusion (p < 0.01, OR: 0.06, CI: 0.01 to 0.35), and dental caries (p = 0.02, OR: 0.22, CI: 0.04 to 1.04) were observed. The OHRQoL overall mean score and subscales were relatively low independent of the evaluated group (p > 0.05). The association between presence and absence of impact with bruxism or other variables showed no statistical relationship (p > 0.05). It could be concluded that childhood bruxism is related to respiratory problems, dental wear, dental caries, and malocclusion. Despite being a topic that demands special care in dentistry, bruxism does not significantly affect the OHRQoL.

    Abstract Aims: To correlate binge drinking (BD) with alcohol-related problems (ARP) in the Brazilian population. Methods: A representative cross-sectional survey was conducted in 143 Brazilian cities. Associations between the frequencies of BD and ARP were gathered using an ordered logit regression model. Results: Higher BD frequencies significantly increased the chance of injury in accidents, job loss, and involvement in intense arguments and assaults over the year. High frequency in BD increases the odds of all ARP. Conclusion: There is a dose-response association between the frequency BD and ARP and is therefore a possible target for public prevention policies. PMID:24829095

  16. Stochastic partial differential equations in turbulence related problems

    Chow, P.-L.

    1978-01-01

    The theory of stochastic partial differential equations (PDEs) and problems relating to turbulence are discussed by employing the theories of Brownian motion and diffusion in infinite dimensions, functional differential equations, and functional integration. Relevant results in probablistic analysis, especially Gaussian measures in function spaces and the theory of stochastic PDEs of Ito type, are taken into account. Linear stochastic PDEs are analyzed through linearized Navier-Stokes equations with a random forcing. Stochastic equations for waves in random media as well as model equations in turbulent transport theory are considered. Markovian models in fully developed turbulence are discussed from a stochastic equation viewpoint.

  19. Optimum profit model considering production, quality and sale problem

    2011-12-01

    Chen and Liu ['Procurement Strategies in the Presence of the Spot Market-an Analytical Framework', Production Planning and Control, 18, 297-309] presented the optimum profit model between the producers and the purchasers for the supply chain system with a pure procurement policy. However, their model with a simple manufacturing cost did not consider the used cost of the customer. In this study, the modified Chen and Liu's model will be addressed for determining the optimum product and process parameters. The authors propose a modified Chen and Liu's model under the two-stage screening procedure. The surrogate variable having a high correlation with the measurable quality characteristic will be directly measured in the first stage. The measurable quality characteristic will be directly measured in the second stage when the product decision cannot be determined in the first stage. The used cost of the customer will be measured by adopting Taguchi's quadratic quality loss function. The optimum purchaser's order quantity, the producer's product price and the process quality level will be jointly determined by maximising the expected profit between them.

  20. Origins and development of the Cauchy problem in general relativity

    2015-06-01

    The seminal work of Yvonne Choquet-Bruhat published in 1952 demonstrates that it is possible to formulate Einstein's equations as an initial value problem. The purpose of this article is to describe the background to and impact of this achievement, as well as the result itself. In some respects, the idea of viewing the field equations of general relativity as a system of evolution equations goes back to Einstein himself; in an argument justifying that gravitational waves propagate at the speed of light, Einstein used a special choice of coordinates to derive a system of wave equations for the linear perturbations on a Minkowski background. Over the following decades, Hilbert, de Donder, Lanczos, Darmois and many others worked to put Einstein's ideas on a more solid footing. In fact, the issue of local uniqueness (giving a rigorous justification for the statement that the speed of propagation of the gravitational field is bounded by that of light) was already settled in the 1930s by the work of Stellmacher. However, the first person to demonstrate both local existence and uniqueness in a setting in which the notion of finite speed of propagation makes sense was Yvonne Choquet-Bruhat. In this sense, her work lays the foundation for the formulation of Einstein's equations as an initial value problem. Following a description of the results of Choquet-Bruhat, we discuss the development of three research topics that have their origin in her work. The first one is local existence. One reason for addressing it is that it is at the heart of the original paper. Moreover, it is still an active and important research field, connected to the problem of characterizing the asymptotic behaviour of solutions that blow up in finite time. As a second topic, we turn to the questions of global uniqueness and strong cosmic censorship. These questions are of fundamental importance to anyone interested in justifying that the Cauchy problem makes sense globally. They are also closely

  1. Improving Multi-Objective Management of Water Quality Tipping Points: Revisiting the Classical Shallow Lake Problem

    2015-12-01

    Recent multi-objective extensions of the classical shallow lake problem are useful for exploring the conceptual and computational challenges that emerge when managing irreversible water quality tipping points. Building on this work, we explore a four objective version of the lake problem where a hypothetical town derives economic benefits from polluting a nearby lake, but at the risk of irreversibly tipping the lake into a permanently polluted state. The trophic state of the lake exhibits non-linear threshold dynamics; below some critical phosphorus (P) threshold it is healthy and oligotrophic, but above this threshold it is irreversibly eutrophic. The town must decide how much P to discharge each year, a decision complicated by uncertainty in the natural P inflow to the lake. The shallow lake problem provides a conceptually rich set of dynamics, low computational demands, and a high level of mathematical difficulty. These properties maximize its value for benchmarking the relative merits and limitations of emerging decision support frameworks, such as Direct Policy Search (DPS). Here, we explore the use of DPS as a formal means of developing robust environmental pollution control rules that effectively account for deeply uncertain system states and conflicting objectives. The DPS reformulation of the shallow lake problem shows promise in formalizing pollution control triggers and signposts, while dramatically reducing the computational complexity of the multi-objective pollution control problem. More broadly, the insights from the DPS variant of the shallow lake problem formulated in this study bridge emerging work related to socio-ecological systems management, tipping points, robust decision making, and robust control.

  3. Global symmetry relations in linear and viscoplastic mobility problems

    Kamrin, Ken; Goddard, Joe

    2014-11-01

    The mobility tensor of a textured surface is a homogenized effective boundary condition that describes the effective slip of a fluid adjacent to the surface in terms of an applied shear traction far above the surface. In the Newtonian fluid case, perturbation analysis yields a mobility tensor formula, which suggests that regardless of the surface texture (i.e. nonuniform hydrophobicity distribution and/or height fluctuations) the mobility tensor is always symmetric. This conjecture is verified using a Lorentz reciprocity argument. It motivates the question of whether such symmetries would arise for nonlinear constitutive relations and boundary conditions, where the mobility tensor is not a constant but a function of the applied stress. We show that in the case of a strongly dissipative nonlinear constitutive relation--one whose strain-rate relates to the stress solely through a scalar Edelen potential--and strongly dissipative surface boundary conditions--one whose hydrophobic character is described by a potential relating slip to traction--the mobility function of the surface also maintains tensorial symmetry. By extension, the same variational arguments can be applied in problems such as the permeability tensor for viscoplastic flow through porous media, and we find that similar symmetries arise. These findings could be used to simplify the characterization of viscoplastic drag in various anisotropic media. (Joe Goddard is a former graduate student of Acrivos).

    The determination of DNA and RNA of causative agents by the nucleic acid amplification techniques (NAT) presented in the Russian laboratory diagnosis of infections solely by polymerase chain reaction (PCR) have currently found the widest application in world practice and, in some cases, is a basic procedure for detecting an infectious agent, particularly in the diagnosis of infections caused by human immunodeficiency virus, hepatitis C virus, hepatitis B virus, cytomegalovirus, Chlamydia trachomatis, Neisseria gonorrhoeae, and others. The paper presents the data available in the literature on the main reasons for false positive and false negative results in PCR studies, international and national programs for the outside quality control (OQC) of detection of causative agents for various diseases, by applying NAT. It is emphasized that the regular participation in OQC programs is likely to be useful in improving the quality of PCR studies.

    Sleep problems, especially insomnia, are a common complaint among adults. International studies have shown prevalence rates between 4.7 and 36.2% for sleep difficulties in general, whereas 13.1–28.1% report insomnia symptoms. Sleep problems are associated with lower social and academic performance and can have a severe impact on psychological and physical health. Psychotherapists are suppliers within the public health system. The goal of this study was to outline sleep characteristics, prevalence of sleep problems, insomnia, and associations of quality of life among psychotherapists. A total of 774 psychotherapists (74.7% women; mean age 46 years) participated in the study. Sleep characteristics, sleep problems, well-being, life satisfaction and workload, as well as specific job demands, were assessed via a questionnaire. Analyses revealed that more than 4.2% of the surveyed psychotherapists have difficulties falling asleep, 12.7% often wake up in the night, and 26.6% feel tired, and 3.4% think that their interrupted sleep affects work performance. About 44.1% of them suffer from symptoms of insomnia. Path models showed that insomnia is significantly related to well-being and life satisfaction. PMID:23471477

    Although prominent models of alcohol use and abuse implicate stress as an important motivator of alcohol consumption, research has not consistently identified a relationship between stress and drinking outcomes. Presumably stress leads to heavier alcohol consumption and related problems primarily for individuals who lack other adaptive methods for coping effectively with stressful experiences. To test this hypothesis, we examined four adaptive coping approaches (active coping, planning, suppression of competing activities, and restraint), as predictors of alcohol use and related problems as well as moderators of relations between stress and drinking outcomes in an undergraduate population (N=225). Further, we examined coping motives for drinking as potential mediators of the effects of coping strategies as well as stress by coping strategy interactions. Analyses supported both restraint and suppression of competing activities as moderators of the influence of stress on alcohol use but not problems. The stress by restraint interaction was also evident in the prediction of coping motives, and coping motives were related to higher levels of both weekly drinking and alcohol-related problems. Finally, coping motives for drinking served to mediate the stress by restraint interaction on weekly drinking. Overall, these results suggest that efforts to suppress competing activities and restrain impulsive responses in the face of stress may reduce the risk for heavy drinking during the transition from high school to college.

  11. On the relationships between (relatively) advanced mathematical knowledge and (relatively) advanced problem-solving behaviours

    NASA Astrophysics Data System (ADS)

    2010-03-01

    This article discusses an issue of inserting mathematical knowledge within the problem-solving processes. Relatively advanced mathematical knowledge is defined in terms of three mathematical worlds; relatively advanced problem-solving behaviours are defined in terms of taxonomies of proof schemes and heuristic behaviours. The relationships between mathematical knowledge and problem-solving behaviours are analysed in the contexts of solving an insight geometry problem, posing algebraic problems and calculus exploration. A particularly knowledgeable and skilled university student was involved in all the episodes. The presented examples substantiate the claim that advanced mathematical knowledge and advanced problem-solving behaviours do not always support each other. More advanced behaviours were observed when the student worked within her conceptual-embodied mathematical world, and less advanced ones when she worked within her symbolic and formal-axiomatic worlds. Alternative explanations of the findings are discussed. It seems that the most comprehensive explanation is in terms of the Principle of Intellectual Parsimony. Implications for further research are drawn.

    In 2002, the National Institute on Alcohol Abuse and Alcoholism (NIAAA) issued a report entitled A Call to Action: Changing the Culture of Drinking at U.S. Colleges. Data on the magnitude of college drinking problems in 1998 to 1999 were reported. From 1999 to 2005, the proportion of college students aged 18–24 who drank five or more drinks on a single occasion in the past month increased from 41.7 percent to 45.2 percent. The proportion who drove under the influence of alcohol increased from 26.1 percent to 29.2 percent. Higher percentages of 21- to 24-year-olds engaged in those behaviors than 18- to 20-year-olds, and between 1999 and 2005 the percentage increased among 21- to 24-year-olds but not among those aged 18–20. From 1998 to 2005, unintentional alcohol-related injury deaths increased 3 percent (from 1,442 to 1,825) per 100,000 college students aged 18–24. Alcohol misuse by college students often harms other people through traffic crashes and sexual/other assaults. Research regarding ways to reduce college drinking problems has shown that individual-oriented interventions, particularly screening and brief motivational counseling interventions, social norms interventions, environmental policy changes such as the minimum legal drinking age of 21 and drinking-and-driving laws, and comprehensive college–community programs, can reduce college drinking and related morbidity and mortality. There is a growing need for colleges and surrounding communities to implement interventions shown through research to reduce alcohol misuse among college-aged people. PMID:23579935

  13. On the Gravitational Two-Body Problem in Special Relativity

    NASA Astrophysics Data System (ADS)

    Afanasiev, G. N.; Asanov, R. A.

    The method of POINCARÉ is applied to the consideration of the gravitational two-body problem in the framework of Special Relativity. The formulation of the theory contains two arbitrary functions. A specific choice of these functions leads to the correct description of three crucial experiments, supporting General Relativity, and the time delay of radar signals. However, the gyroscope precession is three times less than that of GR (the realization of this experiment is planned this year). The expansion over the inverse powers of the light velocity being performed approximate Lorentz covariant two-body equations without retardation effects are obtained. These equations are compared with the EIH two-body equations.Translated AbstractÜber das Zweikörperproblem in der speziellen RelativitätstheorieEs wird die POINCARÉ Methode auf das Problem der Gravitationwechselwirkung zweier Körper in der speziellen Relativitätstheorie angewendet. Die Theorie enthält zwei beliebige Funktionen. Im Potentialgrenzfall erhält man bei bestimmter Wahl dieser Funktionen eine richtige Beschreibung der drei bekannten Effekte in der allgemeinen Relativitätstheorie und des Zeitverzögerungseffektes von Radarsignalen. Die Größe der Präzession des Gyroskops ergibt sich dreimal kleiner als in der Einsteinschen Theorie (die experimentelle Überprüfung dieses Effektes ist für 1980 geplant). Mit Hilfe einer inversen Potenzreihenentwicklung nach der Lichtgeschwindigkeit wurden genäherte Lorentz-kovariante Gleichungen für das Zweikörperproblem erhalten, in denen Retardierungseffekte fehlen. Es wird der Zusammenhang mit anderen Versuchen, Lorentz-kovariante Gleichungen für das Zweikörperproblem aufzustellen, erörtert.

  14. Relationships between undergraduates' argumentation skills, conceptual quality of problem solutions, and problem solving strategies in introductory physics

    NASA Astrophysics Data System (ADS)

    Rebello, Carina M.

    This study explored the effects of alternative forms of argumentation on undergraduates' physics solutions in introductory calculus-based physics. A two-phase concurrent mixed methods design was employed to investigate relationships between undergraduates' written argumentation abilities, conceptual quality of problem solutions, as well as approaches and strategies for solving argumentative physics problems across multiple physics topics. Participants were assigned via stratified sampling to one of three conditions (control, guided construct, or guided evaluate) based on gender and pre-test scores on a conceptual instrument. The guided construct and guided evaluate groups received tasks and prompts drawn from literature to facilitate argument construction or evaluation. Using a multiple case study design, with each condition serving as a case, interviews were conducted consisting of a think-aloud problem solving session paired with a semi-structured interview. The analysis of problem solving strategies was guided by the theoretical framework on epistemic games adapted by Tuminaro and Redish (2007). This study provides empirical evidence that integration of written argumentation into physics problems can potentially improve the conceptual quality of solutions, expand their repertoire of problem solving strategies and show promise for addressing the gender gap in physics. The study suggests further avenues for research in this area and implications for designing and implementing argumentation tasks in introductory college physics.

    We conducted this study to fill the noted gap in the available literature by evaluating the prevalence of poor sleep quality in this understudied population and to explore the relationship between sleep quality and psychological problems among undergraduates in Thailand. This study used a cross-sectional survey. Self-administrated questionnaires included the Pittsburgh Sleep Quality Index (PSQI), the Epworth Sleepiness Scale, the Depression, Anxiety and Stress Scale and the Thai General Health Questionnaire. The study group included 1,055 undergraduates, aged 18-25 years. The prevalence of poor sleep quality was 42.4%. Students classified as poor quality sleepers reported significantly more psychological problems, indicating a linear trend of progressively worse global sleep quality associated with greater mood and anxiety symptomatology. Prospective studies that include objective measures of sleep duration and quality are needed to more fully develop focused health promotion strategies for Southeast Asian undergraduates.

    Quality of smartphone apps related to panic: smartphone apps have a growing role in health care. This study assessed the quality of English-language apps for panic disorder (PD) and compared paid and free apps. Keywords related to PD were entered into the Google Play Store search engine. Apps were assessed using the following quality indicators: accountability, interactivity, self-help score (the potential of smartphone apps to help users in daily life), and evidence-based content quality. The Brief DISCERN score and the criteria of the “Health on the Net” label were also used as content quality indicators as well as the number of downloads. Of 247 apps identified, 52 met all inclusion criteria. The content quality and self-help scores of these PD apps were poor. None of the assessed indicators were associated with payment status or number of downloads. Multiple linear regressions showed that the Brief DISCERN score significantly predicted the content quality and self-help scores. Poor content quality and self-help scores of PD smartphone apps highlight the gap between their technological potential and the overall quality of available products. PMID:26236242

    Multifacility dialysis groups are frequently interested in improving overall quality and find that there are major differences between individual units. Upper management must consider what strategy is needed for the whole company and what strategy must be formulated by individual facilities. To make substantive changes, management must decide to adopt a new culture of true teamwork, drive out fear, and emphasize leadership and education both at the management level and in the individual unit. Both at the corporate and unit levels, leaders must be chosen who are able to recognize people who have the ability, the educational background, the enthusiasm, and the time to direct change. Empowering the individual units and individual employees to make changes and be enthusiastic about improvement is the key to success. PMID:14629606

    Images obtained with the Southern African Large Telescope (SALT) during its commissioning phase in 2006 showed degradation due to a large focus gradient, astigmatism, and higher order optical aberrations. An extensive forensic investigation exonerated the primary mirror and the science instruments before pointing to the mechanical interface between the telescope and the spherical aberration corrector, the complex optical subassembly which corrects the spherical aberration introduced by the 11-m primary mirror. Having diagnosed the problem, a detailed repair plan was formulated and implemented when the corrector was removed from the telescope in April 2009. The problematic interface was replaced, and the four aspheric mirrors were optically tested and re-aligned. Individual mirror surface figures were confirmed to meet specification, and a full system test after the re-alignment yielded a root mean square wavefront error of 0.15 waves. The corrector was reinstalled in August 2010 and aligned with respect to the payload and primary mirror. Subsequent on-sky tests revealed spurious signals being sent to the tracker by the auto-collimator, the instrument that maintains the alignment of the corrector with respect to the primary mirror. After rectifying this minor issue, the telescope yielded uniform 1.1 arcsec star images over the full 10-arcmin field of view.

    A controlled study was conducted in Lebanon over a period of 12 months to determine bacterial regrowth in a small network supplying the Beirut suburb of Naccache that had a population of about 3,000. The residential area, which is fed by gravity, is supplied twice a week with chlorinated water from two artesian wells of a confined aquifer. A significant correlation was detected between the turbidity and the levels of heterotrophic plate count bacteria (HPC) in the samples from the distribution network as well as from the artesian wells. However, a negative significant correlation was found between the temperature and the HPC count in the samples collected from the source. A statistically significant increase in counts, possibly due to regrowth, was repeatedly established between two sampling points lying on a straight distribution line but 1 km apart. Faecal coliforms were detected in the source water but none in the network except during a pipe breakage incident with confirmed Escherichia coli reaching 40 CFU/100 mL. However, coliforms such as Citrobacter freundii, Enterobacter agglomerans, E. cloacae and E. skazakii were repeatedly isolated from the network, mainly due to inadequate chlorination. A second controlled study was conducted to determine the effect of storage on the microbial quality of household storage tanks (500 L), which were of two main types - galvanized cast iron and black polyethylene. The mean bacterial count increased significantly after 7 d storage in both tank types. A significant difference was found in the mean HPC/mL between the winter and the summer. Highest counts were found April-June although the maximum temperature was reported later in the summer. A positive correlation was established between the HPC/mL and pH, temperature and storage time.

    A respective rank problem solution worksheet was developed focusing on problem solution in training in pharmaceutical management. How the training influenced the instructions given to patients was then evaluated in two pharmacists in the NTT East Kanto Medical Center and three in an Ofuna central hospital. After the five pharmacists underwent the training, the records of 10 medication instructions to patients given by each before and after the training were compared. The records were analyzed based on a point calculation table, and the number of acquisition points was computed. The acquisition points increased significantly after training for all five pharmacists, from a mean of 3.56 before training to a mean of 8.34 after training. Although the acquisition points related to patient education were high, those for intervention during therapeutic monitoring, such as for adverse drug reaction or the selection of appropriate pharmaceuticals were acceptable, increasing to a mean 8.4 items after training compared with 4.4 items before. The respective rank problem solution worksheet is therefore considered useful in improving the quality of training pharmaceutical management.

    Shock waves are steep wavefronts that are fundamental in nature, especially in high-speed fluid flows. When a shock hits an obstacle, or a flying body meets a shock, shock reflection/diffraction phenomena occur. In this paper, we show how several long-standing shock reflection/diffraction problems can be formulated as free boundary problems, discuss some recent progress in developing mathematical ideas, approaches and techniques for solving these problems, and present some further open problems in this direction. In particular, these shock problems include von Neumann's problem for shock reflection-diffraction by two-dimensional wedges with concave corner, Lighthill's problem for shock diffraction by two-dimensional wedges with convex corner, and Prandtl-Meyer's problem for supersonic flow impinging onto solid wedges, which are also fundamental in the mathematical theory of multidimensional conservation laws.

    Obesity is the major nutritional problem affecting industrialised society. According to a recent ISTAT survey, 41% of men and 19% of women in the Italian population suffer from obesity. Obesity is a complex pathological entity with a multiform and often indeterminable etiology. Studies of natural and adopted children and twins suggest that a clear hereditary, constitutional predisposing factor is present in obesity which interacts with environmental conditions. The genetic factor is also suggested by the statistical finding that if neither parent is obese, then only 7-10% of their children will be obese, whereas if one parent is obese, 40-50% of children will probably become obese, and if both parents are obese as many as 70-80% of children will be obese. The risks related to obesity can be broadly categorised as mechanical and metabolic. The former include arthrosis, osteoporosis, degenerative diseases affecting the joints and bone matrix, muscular hypotrophy and respiratory deficits. The major metabolic risks include hypercholesterolemia, altered glycoregulation and hyperuricemia. From an obstetric point of view, apart from the fact that obesity is often associated with sterility, excess weight can often lead to sometimes dramatic complications during pregnancy, involving major risks for both mother and fetus. From a gynecological point of view the links between obesity, tumours and menopause are well known.

    Whereas socialization influences in early childhood have been linked to children's emerging internalizing problems and prosocial behavior, relatively few studies have examined how NE might moderate such associations in both advantageous and maladaptive ways. Furthermore, more research is needed to evaluate the impact of sibling relationships as an influential socialization influence on these child outcomes. In the current study we examined how NE might differentially moderate the associations between quality of relationships with siblings and both internalizing problems and social skills at school entry. NE moderated the effects of positive and destructive sibling relationship quality on child internalizing problems. Specifically, for boys high on NE, more positive sibling relationship quality predicted fewer internalizing problems, but more destructive sibling conflict predicted more internalizing problems. NE also moderated the effects of destructive sibling conflict on child social skills. For boys high on NE, destructive sibling conflict predicted fewer social skills. Boys high on NE appear to show greater susceptibility to the effects of sibling socialization on child outcomes, relative to boys low on NE. The implications of these interactions are discussed with respect to differential susceptibility theory.

    2008-07-01

    Qualitative interviews on family and financial problems from 332 adolescents, young, middle-aged, and older adults, demonstrated that developmentally relevant goals predicted problem-solving strategy use over and above problem domain. Four focal goals concerned autonomy, generativity, maintaining good relationships with others, and changing another person. We examined both self- and other-focused problem-solving strategies. Autonomy goals were associated with self-focused instrumental problem solving and generative goals were related to other-focused instrumental problem solving in family and financial problems. Goals of changing another person were related to other-focused instrumental problem solving in the family domain only. The match between goals and strategies, an indicator of problem-solving adaptiveness, showed that young individuals displayed the greatest match between autonomy goals and self-focused problem solving, whereas older adults showed a greater match between generative goals and other-focused problem solving. Findings speak to the importance of considering goals in investigations of age-related differences in everyday problem solving.

    The goal of this study was to describe how activists engaged in campaigns to change alcohol policies in inner city areas framed alcohol problems, and whether or not their frameworks reflected major models used in the field, such as the alcoholism as a disease model, an alcohol problems perspective, or a public health approach to alcohol problems. The findings showed that activists’ models shared some aspects with dominant approaches which tend to focus on individuals and to a lesser extent on regulating alcohol marketing and sales. However, activists’ models differed in significant ways by focusing on community level problems with alcohol; on problems with social norms regarding alcohol use; and on the relationship of alcohol use to illicit drugs.

    Given an undirected graph G = (V,E) with a capacity function w : E longrightarrow {Z}^+ on the edges, the sparsest cut problem is to find a vertex subset S ⊂ V minimizing ∑ e ∈ E(S,V ∖ S) w(e)/(|S||V ∖ S|). This problem is NP-hard. The proof can be found in [16]. In the case of unit capacities (i. e. if w(e) = 1 for every e ∈ E) the problem is to minimize |E(S,V ∖ S)|/(|S||V ∖ S|) over all subsets S ⊂ V. While this variant of the sparsest cut problem is often assumed to be NP-hard, this note contains the first proof of this fact. We also prove that the problem is polynomially solvable for graphs of bounded treewidth.

    In the modern urban setting, most individuals spend about 80% of their time indoors and are therefore exposed to the indoor environment to a much greater extent than to the outdoors (Lebowitz 1992). Concomitant with this increased habitation in urban buildings, there have been numerous reports of adverse health effects related to indoor air quality (IAQ) (sick buildings). Most of these buildings were built in the last two decades and were constructed to be energy-efficient. The quality of air in the indoor environment can be altered by a number of factors: release of volatile compounds from furnishings, floor and wall coverings, and other finishing materials or machinery; inadequate ventilation; poor temperature and humidity control; re-entrainment of outdoor volatile organic compounds (VOCs); and the contamination of the indoor environment by microbes (particularly fungi). Armstrong Laboratory (1992) found that the three most frequent causes of IAQ are (1) inadequate design and/or maintenance of the heating, ventilation, and air-conditioning (HVAC) system, (2) a shortage of fresh air, and (3) lack of humidity control. A similar study by the National Institute for Occupational Safety and Health (NIOSH 1989) recognized inadequate ventilation as the most frequent source of IAQ problems in the work environment (52% of the time). Poor IAQ due to microbial contamination can be the result of the complex interactions of physical, chemical, and biological factors. Harmful fungal populations, once established in the HVAC system or occupied space of a modern building, may episodically produce or intensify what is known as sick building syndrome (SBS) (Cummings and Withers 1998). Indeed, SBS caused by fungi may be more enduring and recalcitrant to treatment than SBS from multiple chemical exposures (Andrae 1988). An understanding of the microbial ecology of the indoor environment is crucial to ultimately resolving many IAQ problems. The incidence of SBS related to multiple

    Background: Sensory impairment is a common condition that exerts negative effects on health-related quality of life (HRQoL) in the elderly. This study aimed to determine the relationship between sensory impairment and HRQoL and identify sensory-specific differences in the HRQoL of elderly. Methods: This study used data from the Korean National Health and Nutrition Examination Survey V (2010–2012), analyzing 5,260 subjects over 60 years of age who completed ophthalmic and otologic examinations. Vision and hearing impairment were measured and classified. HRQoL was determined according to the European QoL five dimension test (EQ-5D). Multivariate logistic regression analysis and analysis of covariance were performed to identify relationships between sensory impairment and HRQoL dimensions as well as differences in HRQoL scores. Results: In the final adjusted multivariate model, there was a statistically higher proportion of those with dual sensory impairment who reported problems with mobility (adjusted odds ratio [aOR] 2.30, 95% confidence interval [CI] 1.45–5.03), usual activities (aOR 2.32, 95% CI 1.16–4.64), and pain/discomfort among EQ-5D subcategories (aOR 1.79, 95% CI 1.07–2.97). In the EQ-5D dimensions, the means and standard deviations of vision impairment (0.86 [0.01]) and dual sensory impairment (0.84 [0.02]) appeared meaningfully lower than those for no sensory impairment (0.88 [0.00]) or hearing impairment (0.88 [0.01]); P = .02). Conclusion: Sensory impairment reduces HRQoL in the elderly. Improvement of HRQoL in the elderly thus requires regular screening and appropriate management of sensory impairment. PMID:26258089

  20. Impact of problem finding on the quality of authentic open inquiry science research projects

    2008-11-01

    Problem finding is a creative process whereby individuals develop original ideas for study. Secondary science students who successfully participate in authentic, novel, open inquiry studies must engage in problem finding to determine viable and suitable topics. This study examined problem finding strategies employed by students who successfully completed and presented the results of their open inquiry research at the 2007 Connecticut Science Fair and the 2007 International Science and Engineering Fair. A multicase qualitative study was framed through the lenses of creativity, inquiry strategies, and situated cognition learning theory. Data were triangulated by methods (interviews, document analysis, surveys) and sources (students, teachers, mentors, fair directors, documents). The data demonstrated that the quality of student projects was directly impacted by the quality of their problem finding. Effective problem finding was a result of students using resources from previous, specialized experiences. They had a positive self-concept and a temperament for both the creative and logical perspectives of science research. Successful problem finding was derived from an idiosyncratic, nonlinear, and flexible use and understanding of inquiry. Finally, problem finding was influenced and assisted by the community of practicing scientists, with whom the students had an exceptional ability to communicate effectively. As a result, there appears to be a juxtaposition of creative and logical/analytical thought for open inquiry that may not be present in other forms of inquiry. Instructional strategies are suggested for teachers of science research students to improve the quality of problem finding for their students and their subsequent research projects.

  2. Singular perturbation analysis of AOTV-related trajectory optimization problems

    1990-01-01

    The problem of real time guidance and optimal control of Aeroassisted Orbit Transfer Vehicles (AOTV's) was addressed using singular perturbation theory as an underlying method of analysis. Trajectories were optimized with the objective of minimum energy expenditure in the atmospheric phase of the maneuver. Two major problem areas were addressed: optimal reentry, and synergetic plane change with aeroglide. For the reentry problem, several reduced order models were analyzed with the objective of optimal changes in heading with minimum energy loss. It was demonstrated that a further model order reduction to a single state model is possible through the application of singular perturbation theory. The optimal solution for the reduced problem defines an optimal altitude profile dependent on the current energy level of the vehicle. A separate boundary layer analysis is used to account for altitude and flight path angle dynamics, and to obtain lift and bank angle control solutions. By considering alternative approximations to solve the boundary layer problem, three guidance laws were derived, each having an analytic feedback form. The guidance laws were evaluated using a Maneuvering Reentry Research Vehicle model and all three laws were found to be near optimal. For the problem of synergetic plane change with aeroglide, a difficult terminal boundary layer control problem arises which to date is found to be analytically intractable. Thus a predictive/corrective solution was developed to satisfy the terminal constraints on altitude and flight path angle. A composite guidance solution was obtained by combining the optimal reentry solution with the predictive/corrective guidance method. Numerical comparisons with the corresponding optimal trajectory solutions show that the resulting performance is very close to optimal. An attempt was made to obtain numerically optimized trajectories for the case where heating rate is constrained. A first order state variable inequality

    OBJECTIVE: To assess the health related quality of life and psychological wellbeing of patients with hypertrophic cardiomyopathy, to correlate these with symptoms, clinical, and psychosocial factors. DESIGN: Questionnaire distributed to 171 hypertrophic cardiomyopathy patients aged at least 14 years, selected at random from a dataset of 480 patients. Assessments included the Short Form 36 (SF-36) Health Survey, the Hospital Anxiety and Depression questionnaire, and measures of adjustment, worry, and patient satisfaction. RESULTS: There was an 80.1% response rate to the questionnaire. Patients had severe limitations in all eight dimensions of quality of life assessed by the SF-36: physical functioning, role limitations owing to physical problems, role limitations owing to emotional problems, social functioning, mental health, general health perceptions, vitality, and bodily pain. Levels of anxiety and depression were also high compared with population norms. Quality of life was particularly impaired in patients with chest pain and dyspnoea, but was less consistently related to clinical cardiological measures. Adjustment to the condition and patient satisfaction were generally good. In multivariate analysis, quality of life was associated with a combination of symptom patterns and psychosocial factors. No differences in quality of life, anxiety or depression were observed between patients with no known family history, those with familial cardiomyopathy, and patients with a family history of premature sudden death. CONCLUSIONS: Hypertrophic cardiomyopathy is associated with substantial restrictions in health related quality of life. Symptoms, adjustment, and quality of interactions with clinical staff contribute to these limitations. Recognition of the problems confronted by patients with hypertrophic cardiomyopathy requires continued efforts at education both of the public and health professionals. PMID:9326995

    Quality of life characteristics, hypoglycemic episodes and patients' attitude toward them were estimated in the patients with type 2 diabetes mellitus based on the modern recommendations for the patient-oriented treatment with metformin in combination with sulfonylurea derivatives (M+S) therapy, traditional approach, n = 83) and metformin in combination with vildagliptin (M+V therapy, innovative approach, n = 111). M+V therapy ensured a higher quality of life than M+S therapy based on all SF-36 scales. Quality of life parameters corresponded to population norms in most patients given M+V therapy and only in 52% of those treated with M+S. The frequency of hypoglycemic episodes, related concerns, and other problems associated with this condition were less apparent in case of M+V therapy. Transition from M+S to M+V therapy resulted in the improvement of quality of life and reduction in the frequency of hypoglycemia. Quality of life did not change after transition to M+S therapy while the frequency of hypoglycemia and the number of related problems increased. HbA1c levels were similar in both groups (0.8% difference). According to patients' reports M+V therapy is more efficient than M+S; these data allow to comprehensively evaluate the efficacy of therapy and monitor the health state of diabetic patients in the course of treatment.

    The family is the key support network for children with autism spectrum disorder (ASD), in many cases into adulthood. The Family Quality of Life (FQOL) construct encompasses family satisfaction with both internal and external dynamics, as well as support availability. Therefore, although these families face considerable risk in raising a child with a disability, the FQOL outcome is conceptualized as representative of a continuum of family adaptation. This study examined the role of child characteristics, including adaptive functioning and behaviour problems, in relation to FQOL. Eighty-four caregivers of children and adolescents (range = 6-18 years) with ASD participated, completing questionnaires online and by telephone. Adaptive functioning, and specifically daily living skills, emerged as a significant predictor of FQOL satisfaction, after accounting for behavioural and demographic characteristics, including child age, gender, perceived disability severity, and behavioural problems, as well as family income. Furthermore, there were significant differences across each domain of FQOL when groups were separated by daily living skill functioning level ('low,' 'moderately low,' and 'adequate'). The results suggest that intervention strategies targeting daily living skills will likely have beneficial effects for both individual and family well-being, and may reduce family support demands.

  6. HACCP-based quality risk management approach to udder health problems on dairy farms

    PubMed Central

    2009-01-01

    Against the background of prevailing udder health problems on dairy farms, this paper discusses a new approach to mastitis control. Current udder health control programmes, such as the 'five-point plan', are highlighted and their drawbacks indicated. The concept and principles of hazard analysis critical control points (HACCP) are introduced. The eight core elements of this concept are dealt with by using the example of a dairy herd with a mastitis problem due to Staphylococcus aureus. The various steps to be taken in the development of a HACCP-based quality risk management programme are illustrated through the application of core elements. Finally, it is shown that the HACCP key words, structure, organisation, planning, communication and formalisation; which do not frequently appear in conventional herd health and production management programmes can contribute to better udder health. The role of the veterinarian can be paramount and of added value, if he/she is willing to invest in new knowledge and skills, such as the HACCP concept, farm economics, animal nutrition, and particularly the role of coach to the dairy farmer in the implementation of preventative measures in relation to udder health.

    In a cross-sectional study, we sent a self-administered questionnaire to all the women's shelters in Norway to describe health-related quality of life among women who had experienced violence from an intimate partner. Every woman who could understand Norwegian and was staying at a women's shelter in Norway for more than 1 week from October 2002 to May 2003 was asked to participate. We described violence by intimate partners by using the Severity of Violence against Women Scale and the Psychological Maltreatment of Women Index. We used the SF-36 Health Survey to measure health-related quality of life. These women experienced a multitude of threats and actual physical and psychological violence during their partnership. Their health-related quality of life was low and significantly (p<0.001) below the norm for the female population of Norway in all dimensions. The SF-36 mental health dimension was 2.5 standard deviations below the norm. Women at women's shelters in Norway who had experienced domestic violence had very low and clinically significantly reduced health-related quality of life scores. Health care workers must give priority to developing intervention plans for victims of violence from intimate partners.

    The string editing problem for input strings x and y consists of transforming x into y by performing a series of weighted edit operations on x of overall minimum cost. An edit operation on x can be the deletion of a symbol from x, the insertion of a symbol in x or the substitution of a symbol x with another symbol. This problem has a well known O((absolute value of x)(absolute value of y)) time sequential solution (25). The efficient Program Requirements Analysis Methods (PRAM) parallel algorithms for the string editing problem are given. If m = ((absolute value of x),(absolute value of y)) and n = max((absolute value of x),(absolute value of y)), then the CREW bound is O (log m log n) time with O (mn/log m) processors. In all algorithms, space is O (mn).

    2011-01-01

    Pediatric researchers and clinicians increasingly recognize the importance of measuring the impact of childhood disease across many aspects of a child’s life. In this review, we describe four measures of health related quality of life (HRQOL) designed specifically for children with Juvenile Idiopathic Arthritis (JIA). HRQOL generally refers to how an individual feels about aspects of their life in relation to their health. The World Health Organization originally described HRQOL as minimally including: physical, mental, and social health dimensions.1 Subsequent HRQOL definitions, while varied, have incorporated the notion that individuals have an important and distinct viewpoint regarding their disease and the quality of their life.2 They have also often emphasized HRQOL’s subjective nature.2 These features present unique challenges when measuring HRQOL in children. Cognizant of these issues, we review the development and psychometric properties of the Pediatric Quality of Life Inventory (PedsQL) Rheumatology Module 3.0, the Juvenile Arthritis Quality of Life Questionnaire (JAQQ), the Paediatric Rheumatology Quality of Life Scale (PRQL), and the Childhood Arthritis Health Profile (CAHP).

    2013-01-01

    Objectives. We examined the relationship between state-level income inequality and alcohol outcomes and sought to determine whether associations of inequality with alcohol consumption and problems would be more evident with between-race inequality measures than with the Gini coefficient. We also sought to determine whether inequality would be most detrimental for disadvantaged individuals. Methods. Data from 2 nationally representative samples of adults (n = 13 997) from the 2000 and 2005 National Alcohol Surveys were merged with state-level inequality and neighborhood disadvantage indicators from the 2000 US Census. We measured income inequality using the Gini coefficient and between-race poverty ratios (Black–White and Hispanic–White). Multilevel models accounted for clustering of respondents within states. Results. Inequality measured by poverty ratios was positively associated with light and heavy drinking. Associations between poverty ratios and alcohol problems were strongest for Blacks and Hispanics compared with Whites. Household poverty did not moderate associations with income inequality. Conclusions. Poverty ratios were associated with alcohol use and problems, whereas overall income inequality was not. Higher levels of alcohol problems in high-inequality states may be partly due to social context. PMID:23237183

    Elderly abuse victims and a nonabused control group were compared to test the widely accepted proposition that such abuse results from the burden and stress placed on those caring for infirm and dependent elderly people. The study found substantially more support for the idea that abuse is associated with personality problems of the caregiver. PMID:2712152

    The way in which the quality of life related to health (HRQoL) is affected by the nutritional status of the patient is a subject of constant interest and permanent debate. The purpose of the present paper is to review those studies that relate HRQoL to nutritional status and examine the tools (questionnaires) that they use to investigate this relationship. A critical review of published studies was carried out via an investigation of the following databases: MEDLINE (via PubMed); EMBASE; The Cochrane Library; Cumulative Index to Nursing and Allied Health Literature (CINAHL); Institute for Scientific Information (ISI) Web of Science; Latin American and Caribbean Health Sciences Literature (LILACS); Spanish Health Sciences Bibliographic Index (IBECS). The search was carried out from the earliest date possible until July 2007.The medical subject heading terms used were 'quality of life', 'nutritional status' and 'questionnaires'. The articles had to contain at least one questionnaire that evaluated quality of life. Twenty-eight documents fulfilling the inclusion criteria were accepted, although none of them used a specific questionnaire to evaluate HRQoL related to nutritional status. However, some of them used a combination of generic questionnaires with the intention of evaluating the same. Only three studies selectively addressed the relationship between nutritional status and quality of life, this evaluation being performed not by means of specific questionnaires but by statistical analysis of data obtained via validated questionnaires.

    Quality controll has fundamental importance in drug safety. During the last 15 years the regulatory changes resulted many problems in the quality controll of pharmaceutical preparations manufactured in pharmacys. The issue of Formulae Normales (FoNo VII.) and the 8th Hungarian Pharmacopoeia raises further questions. Our intentions to show the results have been achived in the area of elaborating new analytical prescriptions (identification and assay) which are crucial due to the obsolescence of previously used prescriptions.

    We are developing a multiphysics simulation tool for Very High-Temperature gascooled Reactors (VHTR). The simulation tool, PRONGHORN, takes advantages of the Multiphysics Object-Oriented Simulation library, and is capable of solving multidimensional thermal-fluid and neutronics problems implicitly in parallel. Expensive Jacobian matrix formation is alleviated by the Jacobian-free Newton-Krylov method, and physics-based preconditioning is applied to improve the convergence. The initial development of PRONGHORN has been focused on the pebble bed corec concept. However, extensions required to simulate prismatic cores are underway. In this progress report we highlight progress on application of PRONGHORN to PBMR400 benchmark problems, extension and application of PRONGHORN to prismatic core reactors, and progress on simulations of 3-D transients.

    Previous studies showed that Pathological Gambling and Attention Deficit/Hyperactivity Disorder (ADHD) often co-occur. The aim of this study was to examine whether ADHD is associated with specific severity patterns in terms of gambling behavior, psychopathology and personality traits. 599 problem and non-problem-gamblers were recruited in addiction clinics and gambling places in France. Subjects were assessed with the Wender-Utah Rating Scale-Child, the Adult ADHD Self-Report Scale, the Mini International Neuropsychiatric Interview, the Temperament and Character Inventory, the South Oaks Gambling Screen and questionnaires assessing gambling related cognitive distortions and gambling habits. 20.7% (n=124) of gamblers were screened positive for lifetime or current ADHD. Results from the multivariate analysis showed that ADHD was associated with a higher severity of gambling-related problems and with more psychiatric comorbidity. Among problem gamblers, subjects with history of ADHD were also at higher risk for unemployment, psychiatric comorbidity and specific dysfunctional personality traits. This study supports the link between gambling related problems and ADHD in a large sample of problem and non-problem gamblers, including problem-gamblers not seeking treatment. This points out the necessity to consider this disorder in the prevention and in the treatment of pathological gambling. PMID:27031593

    1993-05-01

    The effects of rubber dam or cotton roll isolation on the initial quality and later survival of 644 amalgam and 149 anterior enamel-bonded composite resin restorations were evaluated over periods of up to 15 and 10 years, respectively. All restorations were placed by one operator and their quality assessed at the time of finishing, using seven clinical characteristics. The influence of six other clinical parameters on the survival of the restorations was also evaluated. There were no clinically-significant differences present in the initial high quality of the restorations, or in their later survivals, which could be directly related to the use or otherwise of rubber dam. Overall, the restoration survivals were excellent. However, there were significantly more amalgam restoration failures, from bulk fracture, in patients with severe bruxism.

  9. eEurope 2002: Quality Criteria for Health related Websites

    PubMed Central

    2002-01-01

    Background A number of organisations have begun to provide specific tools for searching, rating, and grading this information, while others have set up codes of conduct by which site providers can attest to their high quality services. The aim of such tools is to assist individuals to sift through the mountains of information available so as to be better able to discern valid and reliable messages from those which are misleading or inaccurate. Objective Recognising that European citizens are avid consumers of health related information on the internet and recognising that they are already using the types of rating system described above, the European Council at Feira on June 19-20 2000 supported an initiative within eEurope 2002 to develop a core set of Quality Criteria for Health Related Websites. The specific aim was to draw up a commonly agreed set of simple quality criteria on which Member States, as well as public and private bodies, may draw in the development of quality initiatives for health related websites. These criteria should be applied in addition to relevant Community law. Methods A meeting was held during 2001 which drew together key players from Government departments, International Organisations, non-governmental organisations and industry, to explore current practices and experiments in this field. Some sixty invited participants from all the Member States, Norway, Switzerland, and the United States of America took part in the meeting of June 7-8, 2001: they included delegates from industrial, medical, and patient interest groups, delegates from Member States' governments, and key invited speakers from the field of health information ethics. These individuals, and many others, also took part in the web-based consultation which was open from august to November 2001. Results The broad headings for quality criteria identified include Transparency and Honesty, Authority, Privacy and data protection, Updating of information, Accountability

  10. Defining and assessing health-related quality of life.

    1999-11-01

    In recent years, there has been an increasing interest in quality of life assessment in clinical research and practice, as well as in public health and policy analysis. Indicators of health-related quality of life are important not only for health professionals and their patients, but also for health administrators and health economists in health care planning and policy making. Most studies on the outcome of treatments and interventions now include some kind of a quality of life measure. This usually takes a form of an assessment of symptoms and physical functioning, measurement of psychological well-being, life satisfaction, or coping and adjustment. Numerous scales of psychological health, physical health status and physical functioning have been developed for use in the assessment of health outcomes and a wide range of instruments for measurement of health-related quality of life is available. These fall into two broad categories of generic and disease-specific instruments. The selection of an instrument depends upon its measurement properties but also upon the specific context in which the instrument is going to be used. Adequate attention needs to be paid to the translation and validation of instruments for use across countries and cultural contexts.

    In Dentistry, as in other branches of Medicine, it has been recognised that objective measures of disease provide little insight into the impact of oral disorders on daily living and quality of life. A significant body of development work has been undertaken to provide health status measures for use as outcome measures in dentistry. In descriptive population studies, poor oral health related quality of life is associated with tooth loss. There is a less extensive literature of longitudinal clinical trials, and measurement of change and interpretation of change scores continues to pose a challenge. This paper reviews the literature regarding the development and use of these oral health related QoL measures and includes an appraisal of future research needs in this area. PMID:14514355

  13. Learning Problems Related to the Concept of Field

    NASA Astrophysics Data System (ADS)

    Bradamante, Francesca; Michelini, Marisa; Stefanel, Alberto

    The concept of field has formed itself through a process of elaboration of concepts both on the historical level, and on that of mathematic formalism (integral or differential approach, Lagrangian and Hamiltonian formalism), and in the relationship between mathematics and physics. In didactic tradition it is used as an example of the formalised analogical process. Its phenomenological aspects and its characteristics of time and space are only partially described for the various types of field, mixing the descriptive and interpretative levels. In this review we select some of the main teaching-learning problems and student's diffculties with learning the concept of field, that many researches have stressed, such as: the concept of field and its representation by lines of force, the difference between field and force, the connection between field and its sources, the concept of the field's superposition and the interpretation of mathematical formulas, the application of the third principle of dynamics, the motion of the field's characteristic particles in the field itself. We consider the field in static situations, because these learning problems are fundamental and basic for when we will pass to dynamic situations (electromagnetic field).

  14. Inverse spin glass and related maximum entropy problems.

    PubMed

    Castellana, Michele; Bialek, William

    2014-09-12

    If we have a system of binary variables and we measure the pairwise correlations among these variables, then the least structured or maximum entropy model for their joint distribution is an Ising model with pairwise interactions among the spins. Here we consider inhomogeneous systems in which we constrain, for example, not the full matrix of correlations, but only the distribution from which these correlations are drawn. In this sense, what we have constructed is an inverse spin glass: rather than choosing coupling constants at random from a distribution and calculating correlations, we choose the correlations from a distribution and infer the coupling constants. We argue that such models generate a block structure in the space of couplings, which provides an explicit solution of the inverse problem. This allows us to generate a phase diagram in the space of (measurable) moments of the distribution of correlations. We expect that these ideas will be most useful in building models for systems that are nonequilibrium statistical mechanics problems, such as networks of real neurons. PMID:25260004

    Background We examined the relationship between vitamin D status and health-related quality of life, and explored other related factors in the general Korean population. Methods We used data from the 2007–2012 Korea National Health and Nutrition Examination Survey on 14,104 adults, aged 20–49 years, who had consented to serum vitamin D measurement and answered health-related quality of life questions. EuroQol-5 was used for measurement. Serum vitamin D levels were measured at intervals of 0–9.99, 10–19.99, 20–29.99, and ≥30 ng/mL. Results Participants with higher serum vitamin D (serum 25-hydroxyvitamin D) levels were significantly less likely to report problems with depression and anxiety. After adjustment for age, gender, income level, education level, marital status, alcohol consumption, smoking status, and the existence of depressive disorders, the odds ratio for reporting a problem with depression and anxiety was 0.60 (95% confidence interval [CI], 0.39–0.91). The odds ratio for the prevalence of any problem was 0.69 (95% CI, 0.53–0.89) before adjustment, but was not statistically significant after adjustment. No significant associations were observed for problems with mobility, self-care, usual activity, or pain and discomfort. Conclusion This is the first study to examine the associations between vitamin D and health-related quality of life for the general Korean population. Vitamin D status was not significantly associated with the dimensions of EuroQol-5 except for depression and anxiety problems. PMID:27468340

    Health problems are self-reported by up to 64% of travellers to the developing world. Traditionally, rheumatic symptoms are accorded little significance, but many travellers do return home with musculoskeletal complaints. The assessment of these patients is often hindered by the Western clinician's lack of familiarity with the types of infections that the patient may have encountered while travelling. Standard serological tests for autoimmune diseases can be unreliable in the setting of concomitant tropical infection, and these infections themselves can have musculoskeletal manifestations. Even in the absence of tropical infection, laboratory investigation of musculoskeletal symptoms in individuals of different ethnicities is challenging due to genetic and physiological variation. This review focusses on addressing the impact global migration has had on rheumatological clinical practice.

  8. Symplectic structures related with higher order variational problems

    Kijowski, Jerzy; Moreno, Giovanni

    2015-06-01

    In this paper, we derive the symplectic framework for field theories defined by higher order Lagrangians. The construction is based on the symplectic reduction of suitable spaces of iterated jets. The possibility of reducing a higher order system of partial differential equations to a constrained first-order one, the symplectic structures naturally arising in the dynamics of a first-order Lagrangian theory, and the importance of the Poincaré-Cartan form for variational problems, are all well-established facts. However, their adequate combination corresponding to higher order theories is missing in the literature. Here we obtain a consistent and truly finite-dimensional canonical formalism, as well as a higher order version of the Poincaré-Cartan form. In our exposition, the rigorous global proofs of the main results are always accompanied by their local coordinate descriptions, indispensable to work out practical examples.

    1994-11-28

    Recent developments in China's oil market have reignited the interest of multinational oil and gas companies in China. New onshore and offshore blocks are being granted, and the Tarim basin has been opened to foreign participation for the first time. Foreign participation is also being sought in refining and other downstream areas. Though Chinese officials have long been viewed as difficult negotiators, the tax provisions applicable to oil and gas exploration and production in China are some of the more generous in the area. This article describes some of the relevant features of the system and some of the problem areas. The paper describes production sharing contracts, applicable taxes, gross income determination, taxable income, tax consolidation, overseas charges, and withholding taxes on payments to subcontractors and employees.

  10. Relating watershed nutrient loads to satellite derived estuarine water quality

    NASA Astrophysics Data System (ADS)

    Lehrter, J. C.; Le, C.

    2015-12-01

    Nutrient enhanced phytoplankton production is a cause of degraded estuarine water quality. Yet, relationships between watershed nutrient loads and the spatial and temporal scales of phytoplankton blooms and subsequent water quality impairments remain unquantified for most systems. This is partially due to a lack of observations. In many systems, satellite remote sensing of water quality variables may be used to supplement limited field observations and improve understanding of linkages to nutrients. Here, we present the results from a field and satellite ocean color study that quantitatively links nutrients to variations in estuarine water quality endpoints. The study was conducted in Pensacola Bay, Florida, an estuary in the northern Gulf of Mexico that is impacted by watershed nutrients. We developed new empirical band ratio algorithms to retrieve phytoplankton biomass as chlorophyll a (chla), colored dissolved organic matter (CDOM), and suspended particulate matter (SPM) from the MEdium Resolution Imaging Spectrometer (MERIS). MERIS had suitable spatial resolution (300-m) for the scale of Pensacola Bay (area = 370 km2, mean depth = 3.4 m) and a spectral band centered at wavelength 709 nm that was used to minimize the effect of organic matter on chla retrieval. The algorithms were applied to daily MERIS remote sensing reflectance (level 2) data acquired from 2003 to 2011 to calculate nine-year time-series of mean monthly chla, CDOM, and SPM concentrations. The MERIS derived time-series were then analyzed for statistical relations with time-series of mean monthly river discharge and river loads of nitrogen, phosphorus, dissolved organic carbon, and SPM. Regression analyses revealed significant relationships between river loads and MERIS water quality variables. The simple regression models provide quantitative predictions about how much chla, CDOM, and SPM concentrations in Pensacola Bay will increase with increased river loading, which is necessary information

  12. [Problems related to African customs and ritual mutilations].

    PubMed

    Bourrel, P

    1983-12-01

    Few peoples of the world have completely avoided the practice of ritual mutilation, which at present appears particularly widespread in Africa. This article discusses several forms of mutilation practiced in Africa, most of which are currently rare and disappearing. Cranial deformation due to mechanical pressure in the early years of life was common in Africa and elsewhere, but its origins are difficult to trace. Collars were worn by females in some parts of Africa to elongate the neck, sometimes so weakening the skeletal structure that the head could not be held upright without the device. Many women subjected to their use died at young ages of cerebral vascular accidents. The shortening of the uvula is regarded as a benign mutilation, but could result in infection and death due to the unsanitary conditions in which it was practiced. Perforations of the nose, lips, or ears to permit use of personal adornments were common. Filing of teeth and scarring were other techniques of uncertain origin. Among genital mutilations, circumcision was the most widely known and commonly practiced. It was usually performed on boys of 7-12 years and was invested with ritual significance. Amputation of the gland by unskilled operators or later development of pseudoelephantiasis, nodules, penile fistulas, or stenosis were not rare complications. The custom of excising the clitoris and the labia minora was imported from the Near East and spread west and south with the penetration of Islam. It is still carried out at puberty. Although life-threatening complications are rare, local sequelae including urinary problems, vaginal obstruction, and scleroses leading to vesicovaginal fistulas during childbirth are common. The motive appears to be to prove the subordination of women and the prohibition of all sexual pleasure. Infibulation involves excision of the external genitalia and the creation of an orifice the size of a pencil to allow escape of menstrual fluid and urine. The operation is

    Despite the growing demand of tourism in Malaysia, there are no resolute efforts to develop beaches as tourist destinations. With no incentives to monitor public beaches or to use them in a sustainable manner, they might eventually degenerate in quality as a result of influx of pollutants. This calls for concerted action plans with a view to promoting their sustainable use. The success of such plans is inevitably anchored on the availability of robust quality monitoring schemes. Although significant efforts have been channelled to collation and public disclosure of bacteriological quality data of rivers, beach water monitoring appears left out. This partly explains the dearth of published information related to beach water quality data. As part of an on-going nation-wide surveillance study on the bacteriological quality of recreational beaches, this paper draws on a situation analysis with a view to proffering recommendations that could be adapted for ensuring better beach water quality in Malaysia.

Although significant efforts have been channelled to collation and public disclosure of bacteriological quality data of rivers, beach water monitoring appears left out. This partly explains the dearth of published information related to beach water quality data. As part of an on-going nation-wide surveillance study on the bacteriological quality of recreational beaches, this paper draws on a situation analysis with a view to proffering recommendations that could be adapted for ensuring better beach water quality in Malaysia.

    Background and aims. Diabetic patients display an increased risk of oral disorders, and oral health related quality of life (OHRQL) might affect their management and treatment modalities. The aim of the present study was to determine OHRQL and associated parameters in patients with diabetes. Materials and methods. In this study two hundred patients were recruited from the diabetes clinic in Mustafa Khomeini Hospital in Tehran, Iran. OHRQL was assessed using Oral Health Impact Profile Questionnaire (OHIP-20). Also, another questionnaire was designed which contained questions regarding participants' knowledge about oral complications of diabetes and oral health behavior. OHRQL was categorized as low and good. Data were analyzed using logistic regression at P = 0.05. Results. Of the diabetic patients assessed, 77.5% were in good and 22.5% were in low categories of OHRQL. This quality was significantly associated with age (OR = 4.03, 95% CI = 1.63-11.29), knowledge about diabetes oral complications (OR = 18.17 95% CI = 4.42-158.6), educational level (OR = 26.31 95% CI = 4.2-1080.3), referred for dental visit by physician (OR = 3.16 95% CI = 1.48-6.69), frequency of brushing (OR = 10.29 95% CI = 3.96-31.2) and length of time diagnosed with diabetes (OR = 6.21 95% CI = 2.86-13.63). Conclusion. Oral health related quality of life was not negatively affected by diabetes mellitus in the assessed sample. PMID:25587385

    The paper presents a case study of a transsexual patient who underwent a voice pitch elevation surgery performed in Poland for the first time. The human voice is a reflection of the working of hormones and human psyche. This fact is of particular importance in transsexualism, a disorder consisting in incongruence between the individual's biological sex and their identified gender. For many transsexual people, especially of the MTF (male to female) type, who have undergone hormonal and surgical sex change, the voice still presents a major problem, causing difficulties in everyday life. Hormonal treatment does not influence feminisation of the larynx. In the described MTF case, the patient's low androphonic voice was perceived as a male voice. In order to feminise the patient's voice a phonosurgical procedure was performed: the length of the vibrating portion of the vocal folds was shortened by over 50% of their total length by means of suturing of the anterior part of the vocal fold. As a result of the surgical treatment the pitch of voice was raised considerably, with F0 of spoken voice increased from 109 Hz to 209 Hz. The voice range also changed towards female tones, from 59-146 Hz to 148-343 Hz. Pitch elevation positively influenced the patient's subjective voice assessment: total score of the Voice Handicap Index (VHI) improved from 99 to 19 points, and the score of its emotional sub-scale: 39 and 2 points, respectively. The described case of a surgical male-to-female voice change presents one of the dilemmas faced by modern medicine. (Endokrynol Pol 2016; 67 (4): 452-455). PMID:27387248

    Assessment of biochemical responses to therapy is routine in the management of patients with end stage renal disease (ESRD). Assessment of health-related quality of life (HRQOL), however, is less common. Previous research indicates that HRQOL is a meaningful indicator that should be integrated into clinical practice. HRQOL is longitudinally evaluated in in-centre hemodialysis patients using the RAND 36-item Health Survey 1.0. Caregivers incorporate scores from this instrument into their assessment of patient functioning and well-being. HRQOL scores can be utilized to evaluate responses to changes in therapy, and to direct clinical decision-making, adding an important dimension to holistic, quality care for ESRD patients.

    This study examined self- and caregiver-reported health-related quality of life (HRQOL) of 60 adults with Down syndrome (DS) using the QualityMetric Short Form-12 version 2 (SF-12v2). All HRQOL scores exceeded means and fell within one standard deviation of the SF-12v2 normative sample. Similarities between eight self- and caregiver-reported HRQOL scales were found with the exception of role physical scores (impact of health problems on typical accomplishments), which were lower when obtained by caregiver-report. A positive association was found between self- and caregiver-reported physical functioning scores (impact of health problems on physical activity). The SF-12v2 had high construct validity in this study. These findings support the feasibility of measuring HRQOL of adults with DS using self-report rather than reliance on caregiver-report.

  1. Matrix general relativity: a new look at old problems

    2004-01-01

    We develop a novel approach to gravity that we call 'matrix general relativity' (MGR) or 'gravitational chromodynamics' (GCD or GQCD for the quantum version). Gravity is described in this approach not by one Riemannian metric (i.e. a symmetric two-tensor field) but by a multiplet of such fields, or by a matrix-valued symmetric two-tensor field that satisfies certain conditions. We define the matrix extensions of standard constructions of differential geometry including connections and curvatures, and finally, an invariant functional of the new field that reduces to the standard Einstein action functional in the commutative (diagonal) case. Our main idea is the analogy with Yang Mills theory (QCD and the standard model). We call the new degrees of freedom of gravity associated with the matrix structure 'gravitational colour' or simply 'gravicolour' and introduce a new gauge symmetry associated with this degree of freedom. As in the standard model there are two possibilities. First of all, it is possible that at high energies (say at the Planckian scale) this symmetry is exact (symmetric phase), but at low energies it is badly broken, so that one tensor field remains massless (and gives general relativity) and the other ones become massive with masses of Planckian scale. The second possibility is that the additional degrees of freedom of the gravitational field are confined to the Planckian scale. What one sees at large distances are singlets (invariants) of the new gauge symmetry.

    Having an inter-tie between low/medium voltage grid and distributed generation (DG), both exposes to power quality (PQ) problems created by each other. This paper addresses various PQ problems arise due to integration of DG with grid. The major PQ problems are due to unbalanced and non-linear load connected at DG, unbalanced voltage variations on transmission line and unbalanced grid voltages which severely affect the performance of the system. To mitigate the above mentioned PQ problems, a novel integrated control of distribution static shunt compensator (DSTATCOM) is presented in this paper. DSTATCOM control helps in reducing the unbalance factor of PCC voltage. It also eliminates harmonics from line currents and makes them balanced. Moreover, DSTATCOM supplies the reactive power required by the load locally and hence, grid need not to supply the reactive power. To show the efficacy of the proposed controller, several operating conditions are considered and verified through simulation using MATLAB/SIMULINK.

    Short stature has been associated with psychosocial impairments, but whether treatments and achieved height impact on health-related quality of life (HrQoL) and psychological functioning of children/adolescents is still controversial. This study aimed to examine the effects of height deviation and treatment status on psychosocial adaptation outcomes and to identify clinical and psychosocial determinants of internalizing/externalizing problems in a large cohort of short statured children/adolescents from seven European countries. Participants were 345 children aged 8-18 years with a clinical diagnosis of short stature and 421 parents of 4-18 year-old patients. Children and parents reported on psychological problems (Strengths and Difficulties Questionnaire), generic (KIDSCREEN) and condition-specific HrQoL (QoLISSY). According to analyses of covariance, children/adolescents with current short stature presented more parent-reported internalizing problems and lower self- and parent-reported condition-specific HrQoL, compared to patients with an achieved height above -2SD. Treated children self-reported better HrQoL than the untreated group. Hierarchical regression analysis showed that, rather than height-related clinical variables, children's sex, younger age and poorer HrQoL were the best predictors of psychological problems, explaining 39% of the variance in patient- and 42% in parent-reported internalizing problems, and 22% of the variance in patient- and 24% in parent-reported externalizing problems. Treatment status also moderated the negative links between patient-reported HrQoL and internalizing problems, explaining 2% of additional variance. These results suggest that children with current short stature are at greater risk for internalizing problems. Routine assessment of HrQoL in pediatric healthcare may help identify children for referral to specialized psychological assessment and intervention. PMID:27097033

    Assessing climatological trends and extreme events requires high-quality data. However, for many regions of the world, observational data of the desired quality is not available. In order to eliminate errors in the data, quality control (QC) should be applied before data analysis. If the data still contains undetected errors and quality problems after QC, a consequence may be misleading and erroneous results. A region which is seriously affected by observational data quality problems is the Central Andes. At the same time, climatological information on ongoing climate change and climate risks are of utmost importance in this area due to its vulnerability to meteorological extreme events and climatic changes. Beside data quality issues, the lack of metadata and the low station network density complicate quality control and assessment, and hence, appropriate application of the data. Errors and data problems may occur at any point of the data generation chain, e.g. due to unsuitable station configuration or siting, poor station maintenance, erroneous instrument reading, or inaccurate data digitalization and post processing. Different measurement conditions in the predominantly conventional station networks in Bolivia and Peru compared to the mostly automated networks e.g. in Europe or Northern America may cause different types of errors. Hence, applying QC methods used on state of the art networks to Bolivian and Peruvian climate observations may not be suitable or sufficient. A comprehensive amount of Bolivian and Peruvian maximum and minimum temperature and precipitation in-situ measurements were analyzed to detect and describe common data quality problems. Furthermore, station visits and reviews of the original documents were done. Some of the errors could be attributed to a specific source. Such information is of great importance for data users, since it allows them to decide for what applications the data still can be used. In ideal cases, it may even allow to

    In the last 15 years, worse health-related quality of life (QoL) has been reported in patients with pituitary diseases compared with healthy individuals. Different QoL questionnaires have shown incomplete physical and psychological recovery after therapy. Residual impairments often affect QoL even long-term after successful treatment of pituitary adenomas. In this article, knowledge of factors that affect QoL in pituitary diseases is reviewed. The focus is on 5 pituitary diseases: Cushing syndrome, acromegaly, prolactinomas, nonfunctioning pituitary adenomas, and hypopituitarism.

    Parkinson's disease is a disabling and progressive neurological condition characterized by multiple motor and non motor symptoms that contribute to deterioration in quality of life. The diversity of symptoms associated with the disease and its management affect the patients on their physical, social and mental quality of life. The aim of this study was to identify key dimensions of health related quality of life (HRQOL) in a population affected with Parkinson's disease with a degree of mild-moderate impairment. Thirty six patients with Parkinson were recruited. The Hoehn and Yarh scale, the Unified Parkinson's Disease Rate Scale, the scale of activities of daily life and Schwab & England Get Up & Go Test were applied. HRQOL was assessed with the EuroQol-5D and the specific questionnaire Parkinson's Disease Questionnaire-39 items. The dimensions of the PDQ-39, except the PDQ-39 Pain domain and the EuroQol-5D correlated significantly with the severity of the disease. HRQOL was correlated with the functional status of patients. Only the PDQ-39 pain domain correlated with the risk of falls. Our results suggest that the HRQOL of patients with PD, in a state of mild-moderate impairment, is strongly influenced by disease severity and functional status. PMID:21163736

    Aims: To asses self-reported sleep disturbance and its associated factors in 50-60-year-old Menopause women. Settings and Design: This cross sectional study included 700 healthy 50-60-year-old women volunteers who were postmenopausal for at least 1 year. The volunteers were interviewed after providing informed consent. The study questioner included two main aspects: Personal characteristics and the Pittsburgh Sleep Quality Index (PSQI). Data were analyzed by using SPSS 14 software. Results: The mean sleep scale score was 7.84 ± 4.4. Significant correlations had seen between sleep disturbance and characteristics of occupational status, educational status, husband's occupational status, and economical status, and (P = 0.002). There were no significant correlation between sleep disturbance and other personal characteristics, such as age; partner's age; number of children; family size; consumption of tea, coffee, or cola. Conclusions: Sleep disturbance is common in menopausal women. Taking into account the sleep-related personal characteristics, suitable interventions should be taken to improve sleep quality, which is a very important for maintaining the quality of life.

    Abstract: Background: Suicide is the 10th leading cause of death in the United States. Furthermore, intimate partner problems are amid the top precipitating circumstances among suicide decedents. The aim of this study was to determine circumstantial associations of intimate partner problem-related suicides in suicide decedents in Kentucky. Methods: All suicides that were reported to the Kentucky Violent Death Reporting System between 2005 and 2012 were eligible for this study. Multiple logistic regression was used to explore predictors (precipitating health-related problems, life stressors, and criminal/legal issues) of intimate partner problem-related suicides. Results: Of the 4,754 suicides, included in this study, approximately 17% had intimate partner problems prior to suicide. In the adjusted analysis, mental health issues, alcohol problems, history of suicides attempts, suicides precipitated by another crime, and other legal problems increased the odds of having an intimate partner-related suicide. However, having physical health problems, prior to the suicide, decreased the odds of intimate partner-related suicide. Conclusions: These results provide insight for the development of suicide interventions for individuals with intimate partner problems by targeting risk factors that are prevalent among this population. Moreover, these results may help marriage/relationship and/or family/divorce court representatives identify individuals with intimate partner problems more at risk for suicide and alleviate the influence these suicide risk factors have on individuals experiencing Intimate partner problems.

    2005-03-01

    To establish reliable quality criteria for medical websites is of foremost importance in relation to the increasing number of Internet users, both health professionals and lay people, searching for medical information in the mass of these sites. Quality in general refers to a set of features that distinguish one person or thing from others of the same type. The quality of a website is usually related to its content and usability. The first criteria we considered are contents and readability, which must be targeted to the intended type of user. Other important criteria include: transparency, consistency, honesty, references to sources, accountability, respect of privacy, currency of content material, responsibility, and accessibility. Technical criteria are the use of consolidated and standard technologies, soft colours, short page download time. Good medical websites should also follow the suggestions of organizations such as the World Health Organization, the Food and Drug Administration, the European Communities. Another organization, Health On Net Foundation, has issued some guidelines for medical websites, summarized in eight points, fundamental to assign real scientific value to a site. We believe, in agreement with the literature, that it is unnecessary to apply strict rules to medical website developers. We want to stress the importance of guidelines and recommendations to be modified with the development of web technology and the cultural evolution of patient and physicians. In the near future the presence on the Internet of websites certified by national or international medical web authorities will lead users to trust and give their preference to such sites, leading to the self-regulation of website developers and users.

    Introduction: Purpose of this descriptive study is to determine the mental health problems and quality of life levels of college students and examine the relationship between them. Methods: The sample of the study consisted of 429 students continuing their education in Health School at Afyon Kocatepe University. Data were collected by using information form, Brief Symptom Inventory (BSI), SF 36 Quality of Life Scale questionnaires. In the analysis of obtained data, descriptive statistics, t-test, ANOVA and correlation analyses were used. Findings: Mental symptoms which the students got the highest scores from the subscales of BSI were respectively, depression (1.31±0.75), hostility (1.22±0.67) and anxiety (1.00±0.65). Discomfort severity index which is the overall score of the scale was found 1.07±0.61. Relation between state of mind and quality of life was found statistically significant (F: 70.894; p<0.000). When quality of life summary scores examined, it was found out that physical health summary score (48.92±7.93) and mental health summary score (43.44±9.52) points were low. Conclusions: Consequently, according to averages of scores, it can be said that frequency of the mental symptoms of students are high but their quality of life is low. It was found that when students’ quality of life decreased, their mental symptoms increased. PMID:27482164

    [Purpose] To describe the functional consequences of patients with cardiac diseases and analyze associations between activity limitations and quality of life. [Subjects and Methods] Seventy subjects (mean age: 60.1±12.0 years) were being treated by Physical Medicine and Rehabilitation and Cardiology Departments were included in the study. Activity limitations and participation restrictions as perceived by the individual were measured by the Canadian Occupational Performance Measure (COPM). The Nottingham Extended Activities of Daily Living (NEADL) Scale was used to describe limitations in daily living activities. To detect the impact of activity limitations on quality of life the Nottingham Health Profile (NHP) was used. [Results] The subjects described 46 different types of problematic activities. The five most identified problems were walking (45.7%), climbing up the stairs (41.4%), bathing (30%), dressing (28.6%) and outings (27.1%). The associations between COPM performance score with all subgroups of NEADL and NHP; total, energy, physical abilities subgroups, were statistically significant. [Conclusion] Our results showed that patients with cardiac diseases reported problems with a wide range of activities, and that also quality of life may be affected by activities of daily living. COPM can be provided as a patient-focused outcome measure, and it may be a useful tool for identifying those problems. PMID:26311919

    There is a burgeoning interest in selective contracting for specialized hospital services based on volume, price, and quality. The systematic exclusion or inclusion of particular institutions has been extolled by some as an arrangement to reduce costs and by others as a means to increase quality of care. However, little is known about the issues and problems associated with selective contracting based on objective criteria rather than negotiations. Identification of individual institutions with performance significantly better or poorer than expected based on statistical norms is difficult and should be viewed as no more than a first step in evaluating quality and price performance. Actual data on 37 hospitals that provide coronary artery bypass graft surgery in a metropolitan region are used to illustrate some major prospects, problems, and situations arising when certain institutions are considered for exclusion from or inclusion in third-party payment programs. Selective contracting in local areas can potentially decrease duplication of services, reduce cost to purchasers, and lower expected mortality and morbidity for some patient groups. However, these gains must be evaluated against reductions in continuity of care and access to care, potential increases in mortality and morbidity for certain segments of the population, and substantial political problems.

    Many children with autism spectrum disorders (ASD) have co-occurring feeding problems. However, there is limited knowledge about how these feeding habits are related to other behavioral characteristics ubiquitous in ASD. In a relatively large sample of 256 children with ASD, ages 2-11, we examined the relationships between feeding and mealtime…

    Hypotheses that positive affect and fear in infancy moderate later relationships between neighborhood quality and behavior problems were examined in a sample of children from the National Longitudinal Survey of Youth. Results suggested that poor neighborhood quality was associated with antisocial behavior at age 6 for children who in infancy were characterized by either high positive affect and low fear or by low positive affect and high fear. Depression/anxiety increased from age 6 to age 12 for children in poor quality neighborhoods who were characterized in infancy by low positive affect. A combination of low fear and high positive affect in infancy appeared to be protective, as it was associated with decreases in depression/anxiety during childhood. These findings suggest the utility of examining multiple dimensions of temperament and of integrating multiple levels of influence into moderational models to understand and prevent the development of childhood symptomatology.

    This study proposes an eco-innovative design process taking into consideration quality and environmental aspects in prioritizing and solving technical engineering problems. This approach provides a synergy between the Life Cycle Assessment (LCA), the nonquality matrix, the Theory of Inventive Problem Solving (TRIZ), morphological analysis and the Analytical Hierarchy Process (AHP). In the sequence of these tools, LCA assesses the environmental impacts generated by the system. Then, for a better consideration of environmental aspects, a new tool is developed, the non-quality matrix, which defines the problem to be solved first from an environmental point of view. The TRIZ method allows the generation of new concepts and contradiction resolution. Then, the morphological analysis offers the possibility of extending the search space of solutions in a design problem in a systematic way. Finally, the AHP identifies the promising solution(s) by providing a clear logic for the choice made. Their usefulness has been demonstrated through their application to a case study involving a centrifugal spreader with spinning discs.

  5. Health-related quality of life in clinical practice.

    1999-12-01

    This month's question addressed something that many of us perhaps still have not formally incorporated into clinical practice, although we all are interested in our patients' health-related quality of life and want our inventions to result in improvements within this area. This view is exemplified by the response from Australia, which is one of several similar, unpublished, replies from the International Panel on this month's question (others came from Germany and Sweden). As mentioned in the introduction, health-related quality of life is becoming increasingly important as an outcome measure in clinical trials of new therapeutic interventions and several new measures have been and are developed. It is interesting and encouraging to hear about the new developments within this area that are being made by neuroscience nurses in different countries and within different subspecialties around the globe. As reported from the International Panel in here, new HRQL measures are currently developed in Canada and the UK focusing on patients with brains injuries and Huntington's disease (HD), respectively. In contrast to most established measures, the Canadian study has primarily been aimed at the positive aspects of life and not merely absence of the negative ones. Steve Smith in the UK has recently started developing a scale for use in clinical management of patients with HD. As far as I have been able to determine, this is the first measure of this kind to be developed for HD. Anyone who would like to know more about Steve's work or take part thereof is encouraged to contact him at this address above. Despite the fact that there already are several HRQL measures available, there is still a need for new instruments reflecting new aspects of health and disease. In addition, tools need to be designed for challenging conditions not readily addressed by existing measures. The replies from Canada and the UK represent these needs. It will be very interesting to eventually take

    Cancer survivorship is the term used to represent the state or process of living with cancer or living after diagnosis of cancer. Living with cancer or living after cancer--are conditions characteristic to an increasing number of long-term survivors ("society of remission"); health-related quality of life in these individuals is an important indicator of successful treatment and patient's satisfaction. Health-related quality of life in oncological patients has remained one of the main topic of research. The present paper reviews psychosocial outcomes in breast cancer (female disease) and gender-related differences in health-related quality of life in colon cancer survivors. Breast cancer diagnosis is usually associated with several expected psychosocial consequences like psychosocial distress. Specific psychological variables like body image, fear, satisfaction with treatment and cosmetic evaluation may improve general will to live. Women who perceive support from family and friends have better coping and psychological adjustment, while lack of social support is a risk factor for anxiety and depression. Colon cancer remains an important medical and social problem in Poland; polish data showed the following gender-related differences: in patients with stoma, women reported lower level of psychological well-being than men, reported increasing level of stress and loss of control over emotions and behaviours.

    The increased prevalence of obesity represents, currently, one of the major public health issues, due to its consequences on physical and psychological health status as well as on the psychosocial functioning. As defined by the World Health Organization, sexual health is “a state of physical, emotional, mental, and social well-being in relation to sexuality.” The aim of the present study was to explore the relationship between sexual life in obese subjects and quality of life, psychological status, and disability. Methods. 95 obese subjects were recruited from June 2012 to February 2013 and underwent physical examination and measures for the assessment of quality of life, sexual life, psychological status, and disability. Results. In obese subjects sexual life was related to gender, age, psychological status, disability, and quality of life. Conclusion. As obesity is a multifactorial disease, and is accompanied by multiple comorbidities, it is difficult to identify a single causative factor responsible for the impairment of sexual life in obese subjects; thus, a thorough, multidimensional evaluation including sexual function assessment should be performed in obese people.

    Objective To describe the perception of the quality of life in oral health based on the Health-Related Quality of Life instrument in its Spanish version (HRQOL-sp) in Chilean patients with third molar extraction surgery. Patients and methods A cross-sectional study. The HRQOL-sp was administered to dental patients at the Public Hospital in Rio Bueno in southern Chile treated for unilateral third molar extraction between March and June 2014. The instrument was applied by phone survey on the first, third, fifth, and seventh days after surgery. For the ordinal scale, the response was considered interference in the quality of life when patients selected the options “quite a bit of trouble” or “lots of trouble” for oral function and general activity; and selected complications-related signs and symptoms, a pain level score with a Verbal Rating Scale (range 0 to 7), and worst pain perceived. The patient’s sociodemographic data, type of surgery, and the quality of life level were analyzed according to the domains of the HRQOL-sp instrument. Results A total of 106 patients were selected (age: 20.4±7.39 years; 71.7% women) and a total of 127 extracted third molars. On the first day of follow-up, most patients reported interference in their quality of life. The main problems were difficulty opening the mouth (50.94%) and swelling (83.02%). The worst symptom perceived was “bad breath” (>31%) and the worst pain felt was a mean of 4.31±1.62 on the Verbal Rating Scale. All items gradually reduced until the seventh day. Conclusion The HRQOL-sp revealed substantial interference in the quality of life on the first postoperative day. It is suggested that the risk factors associated with quality of life be analyzed and the instrument in Spanish be validated.

    Chinese herbal pieces are a key factor to protecting the quality of the clinical efficacy of traditional Chinese medicine (TCM), and it is one of the basic elements of ensuring the quality of TCM and people's usage safety. However, Chinese herbal pieces has massive problem such as adulteration and counterfeit, dyeing and weighting, pesticide residues, heavy metals in excess of the standards, and all the issues are repeated excessive in the clinic treatment. These issues impacted sound development of production, management and use of TCM, but also brings common people hidden trouble for the clinical safety of medication. Protect and improve the quality of the Chinese herbal pieces demand that continue improve quality system, in-depth scientific research, and strengthen self-discipline and other factors. So it is fundamentally to ensure good quality of Chinese herbal pieces with the color, taste and shape by systematic supervision to it from the source, production, management and research, with strengthened implementation and en- forcement of the "3G".

    Tooth loss is highly prevalent in Brazil, especially among the elderly, where more than three million need bimaxillary dentures. The federal government instituted Specialized Dental Care Centers (SDCC) to remedy this situation. The scope of this study was to evaluate one attribute of these Centers, namely the provision of full conventional dentures (FCD) from the perspective of quality and satisfaction related to this product. A cross-sectional study was conducted with 149 individuals fitted with such dentures in SDCC of Rio Grande do Norte between 2007 and 2009. Data were obtained by questionnaire and clinical examination of FCD regarding its retention, stability, aesthetics, and fixation. From the 233 dentures evaluated, 52.7% of upper FCD and 9.5% of lower FCD were technically satisfactory. With respect to the association between technical quality and satisfaction, the chi-square test indicated that upper FCDs were technically adequate (p = 0.041), particularly in terms of retention (p = 0.002) and stability (p = 0.000) and were associated with patient satisfaction. Thus, the FCD satisfied the users, despite the technical defects. However, this satisfaction may come from the fitting itself rather than its functionality.

    Improving the quality and efficiency of primary health care system is a key challenge. In this regard, problems that have accumulated in the system over the past decade - a weak material base of outpatient-polyclinic institutions, especially in rural areas; a surplus of medical personnel; lack of control by local, regional and central authorities--still remain as serious obstacle. The issue of financing the provided health services, is also particularly important, given the fact that a significant portion of the cost of medical services is covered by the patient directly. And as a consequence, the low level of applications for outpatient-polyclinic assistance due to declining affordability of medical services. In connection with the foregoing, the authors of the paper raise the question of implementing strict, multi-component system of quality control of medical care for patients. In particular, they propose: to base modern organization works on improving the quality of primary health care system on the principles of general management theory; Modern management of service quality should be clearly oriented towards the needs of the population in health care, its structure and dynamics; accessibility, incentives, determined by economic and technological competition characteristic to the market; Modern quality management, regardless of ownership and scale of outpatient-polyclinic establishment should optimally combine the actions, methods and tools that provide, on the one hand--the organization of diagnostic and therapeutic-prophylactic processes meeting the needs of the people, and on the other--the introduction of new methods and means to ensure the modern level of medical care; Schematic diagram of quality control mechanism organically interacts with the market research and includes a block of policy development in terms of quality.

    It is an important public health problem to identify risk factors of health-related quality of life (HRQoL) among the elderly. We recruited subjects from Ansan, Korea, as a subset of the Korean Genome and Epidemiology Study (KoGES), which is an ongoing population study, and followed up their sleep quality for 6 years. Mixed effect models were used to estimate the association between sleep quality and HRQoL, and we found that overall HRQoL was significantly lower to the elderly having poor sleep quality with adjustment for significant covariates although sleep quality showed a significant interaction effect with time for the mental component summary of SF-12. In particular, the elderly having lack of quality sleep appeared to have good general health, but their functional performances were significantly poor.

    We previously reported reduced sperm concentration and motility in fertile men in a U.S. agrarian area (Columbia, MO) relative to men from U.S. urban centers (Minneapolis, MN; Los Angeles, CA; New York, NY). In the present study we address the hypothesis that pesticides currently used in agriculture in the Midwest contributed to these differences in semen quality. We selected men in whom all semen parameters (concentration, percentage sperm with normal morphology, and percentage motile sperm) were low (cases) and men in whom all semen parameters were within normal limits (controls) within Missouri and Minnesota (sample sizes of 50 and 36, respectively) and measured metabolites of eight current-use pesticides in urine samples provided at the time of semen collection. All pesticide analyses were conducted blind with respect to center and case-control status. Pesticide metabolite levels were elevated in Missouri cases, compared with controls, for the herbicides alachlor and atrazine and for the insecticide diazinon [2-isopropoxy-4-methyl-pyrimidinol (IMPY)]; for Wilcoxon rank test, p = 0.0007, 0.012, and 0.0004 for alachlor, atrazine, and IMPY, respectively. Men from Missouri with high levels of alachlor or IMPY were significantly more likely to be cases than were men with low levels [odds ratios (ORs) = 30.0 and 16.7 for alachlor and IMPY, respectively], as were men with atrazine levels higher than the limit of detection (OR = 11.3). The herbicides 2,4-D (2,4-dichlorophenoxyacetic acid) and metolachlor were also associated with poor semen quality in some analyses, whereas acetochlor levels were lower in cases than in controls (p = 0.04). No significant associations were seen for any pesticides within Minnesota, where levels of agricultural pesticides were low, or for the insect repellent DEET (N,N-diethyl-m-toluamide) or the malathion metabolite malathion dicarboxylic acid. These associations between current-use pesticides and reduced semen quality suggest that

    A multidisciplinary team of IEQ and energy researchers has defined a program of priority energy-related IEQ research. This paper describes the methods employed to develop the agenda, and 35 high priority research and development (R&D) project areas related to four broad goals: (1) identifying IEQ problems and opportunities; (2) developing and evaluating energy-efficient technologies for improving IEQ; (3) developing and evaluating energy-efficient practices for improving IEQ; and (4) encouraging or assisting the implementation of technologies or practices for improving IEQ. The identified R&D priorities reflect a strong need to benchmark IEQ conditions in small commercial buildings, schools, and residences. The R&D priorities also reflect the need to better understand how people are affected by IEQ conditions and by the related building characteristics and operation and maintenance practices. The associated research findings will provide a clearer definition of acceptable IEQ that is required to guide the development of technologies, practices, standards, and guidelines. Quantifying the effects of building characteristics and practices on IEQ conditions, in order to provide the basis for development of energy efficient and effective IEQ control measures, was also considered a priority. The development or advancement in a broad range of IEQ tools, technologies, and practices are also a major component of the priority research agenda. Consistent with the focus on ''energy-related'' research priorities, building ventilation and heating, ventilating and air conditioning (HVAC) systems and processes are very prominent in the agenda. Research related to moisture and microbiological problems, particularly within hot and humid climates, is also prominent within the agenda. The agenda tends to emphasize research on residences, small commercial buildings, and schools because these types of buildings have been underrepresented in prior research.

    The relative equilibria for the spherical, finite density three-body problem are identified. Specifically, there are 28 distinct relative equilibria in this problem which include the classical five relative equilibria for the point-mass three-body problem. None of the identified relative equilibria exist or are stable over all values of angular momentum. The stability and bifurcation pathways of these relative equilibria are mapped out as the angular momentum of the system is increased. This is done under the assumption that they have equal and constant densities and that the entire system rotates about its maximum moment of inertia. The transition to finite density greatly increases the number of relative equilibria in the three-body problem and ensures that minimum energy configurations exist for all values of angular momentum.

    The burden imposed by disease recurrence in patients with high-grade gliomas is not well documented. We studied the frequency of self-report symptoms and the effects on health-related quality of life in patients who had recurrent glioblastoma multiforme or anaplastic astrocytoma and who had a Karnofsky performance score > or = 70. Patients completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 Items (QLQ-C30) and the Brain Cancer Module (BCM20) before initiation of treatment for first recurrence of disease. Six symptoms (fatigue, uncertainty about the future, motor difficulties, drowsiness, communication difficulties, and headache) were reported with a frequency > 50% by both groups of patients. An additional two symptoms (visual problems and pain) were also reported with frequencies of > 50% by patients with recurrent glioblastoma multiforme. Most of the symptoms were likely due to recurrence, but previous radiation therapy and on-going corticosteroid treatment may have also been casual factors for fatigue, whereas uncertainty about the future and pain were probably nonspecific for brain cancer. Problems with motor functioning, vision, leg strength, and pain were reported more frequently by patients with recurrent glioblastoma multiforme than by those with recurrent anaplastic astrocytoma. Scores on health-related quality-of-life functioning scales were similar in the two groups. Finally, the scores for patients who had recurrent high-grade gliomas and a Karnofsky performance score > or = 70 were compared with the reported health-related quality of life scores of patients with other cancers. Their scores were similar to those of patients with metastatic cancers and worse than those of patients with localized cancers. PMID:11265231

    Despite progressive disability in sporadic adult-onset ataxia (SAOA), little is known about patients' assessment of their ataxic disorder and its impact on health-related quality of life (Hr-QoL). This study investigated Hr-QoL by means of the following self-administered scales: Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, Beck Depression Inventory (BDI), and the Medical Outcome Study Short Form (SF-36). Twenty-two unselected ataxia patients were included. Sleep-related complaints were found in 9 (41%) of 22 and symptoms of depression in 6 (38%) of 16 patients. Compared to a large german control group, SAOA patients had lower scores in all SF-36 dimensions except for bodily pain. The greatest impairment was found in the domain physical functioning, followed by the domains social functioning and role limitations (emotional problems). There was a significant negative correlation of all nonmotor SF-36 dimensions with the BDI score. Walking aid dependency was significantly correlated with poorer health status perception in several motor and nonmotor domains. In addition, impaired sleep quality was correlated with an impaired general health perception and with bodily pain. The study demonstrates a great impact of SAOA on Hr-QoL. Adequate treatment of depression, motor disability, and impaired sleep quality is essential to improve Hr-QoL in ataxic patients. PMID:17149704

    Problem gambling attracts considerable public stigma, with deleterious effects on mental health and use of healthcare services amongst those affected. However, no research has examined the extent of stigma towards problem gambling within the general population. This study aimed to examine the stigma-related dimensions of problem gambling as perceived by the general public compared to other health conditions, and determine whether the publicly perceived dimensions of problem gambling predict its stigmatisation. A sample of 2000 Australian adults was surveyed, weighted to be representative of the state population by gender, age and location. Based on vignettes, the online survey measured perceived origin, peril, concealability, course and disruptiveness of problem gambling and four other health conditions, and desired social distance from each. Problem gambling was perceived as caused mainly by stressful life circumstances, and highly disruptive, recoverable and noticeable, but not particularly perilous. Respondents stigmatised problem gambling more than sub-clinical distress and recreational gambling, but less than alcohol use disorder and schizophrenia. Predictors of stronger stigma towards problem gambling were perceptions it is caused by bad character, is perilous, non-recoverable, disruptive and noticeable, but not due to stressful life circumstances, genetic/inherited problem, or chemical imbalance in the brain. This new foundational knowledge can advance understanding and reduction of problem gambling stigma through countering inaccurate perceptions that problem gambling is caused by bad character, that people with gambling problems are likely to be violent to other people, and that people cannot recover from problem gambling.

    2012-04-01

    The purpose of this study was to assess whether understanding relational terminology (i.e., more, less, and fewer) mediates the effects of intervention on compare word problems. Second-grade classrooms (N=31) were randomly assigned to one of three conditions: researcher-designed word-problem intervention, researcher-designed calculation intervention, or business-as-usual (teacher-designed) control. Students in word-problem intervention classrooms received instruction on the compare problem type, which included a focus on understanding relational terminology within compare word problems. Analyses, which accounted for variance associated with classroom clustering, indicated that (a) compared with the calculation intervention and business-as-usual conditions, word-problem intervention significantly increased performance on all three subtypes of compare problems and on understanding relational terminology, and (b) the intervention effect was fully mediated by students' understanding of relational terminology for one subtype of compare problems and partially mediated by students' understanding of relational terminology for the other two subtypes.

    This study examined the relationship of negative affect and alcohol use behaviors to baseline respiration and respiratory response to emotional challenge in young adults (N = 138, 48% women). Thoracic-to-abdominal ratio, respiratory frequency and variability, and minute volume ventilation (MVV) were measured during a low-demand baseline task, and emotional challenge (viewing emotionally-valenced, emotionally-neutral, and alcohol-related pictures). Negative Mood and Alcohol Problems principal components were generated from self-report measures of negative affect and mood, alcohol use, and use-related problems. The Negative Mood component was positively related to a thoracic bias when measured throughout the study (including baseline and picture exposure). There was generally greater respiratory activity in response to the picture cues, although not specifically in response to the content (emotional or alcohol-related) of the picture cues. The Alcohol Problems component was positively associated with respiratory reactivity to picture cues, when baseline breathing patterns were controlled. Self-report arousal data indicated that higher levels of negative mood, but not alcohol problems, were associated with greater arousal ratings overall. However, those with alcohol problems reported greater arousal to alcohol cues, compared to emotionally neutral cues. These results are consistent with theories relating negative affect and mood to breathing patterns as well as the relationship between alcohol problems and negative emotions, suggesting that the use of respiratory interventions may hold promise for treating problems involving negative affect and mood, as well as drinking problems.

    The objective of this study was to measure health-related quality of life (HRQL) of children with newly diagnosed specific learning disability (SpLD) using the Child Health Questionnaire-Parent Form 50. We detected clinically significant deficits (effect size > or = -0.5) in 9 out of 12 domains: limitations in family activities, emotional impact on parents, social limitations as a result of emotional-behavioral problems, time impact on parents, general behavior, physical functioning, social limitations as a result of physical health, general health perceptions and mental health; and in both summary scores (psychosocial > physical). Multivariate analysis revealed having > or = 1 non-academic problem(s) (p < 0.0001), attention-deficit hyperactivity disorder (p = 0.005) or first-born status (p = 0.009) predicted a poor psychosocial summary score; and having > or =1 non-academic problem(s) (p = 0.006) or first-born status (p = 0.035) predicted a poor physical summary score. HRQL is significantly compromised in children having newly diagnosed SpLD.

    This study investigated different environmental and contextual factors associated with maltreated children's adjustment in foster care. Participants included 83 children (52 boys), ages 1-7 years, and their foster caregivers. Quality of interaction with the foster caregiver was assessed from direct observation of a free-play situation; foster caregiver attachment state of mind and commitment toward the child were assessed using two interviews; disruptive behavior symptoms were reported by foster caregivers. Results showed that quality of interaction between foster caregivers and children were associated with behavior problems, such that higher-quality interactions were related to fewer externalizing and internalizing problems. Foster caregivers' state of mind and commitment were interrelated but not directly associated with behavior problems of foster children. Type of placement moderated the association between foster caregiver commitment and foster child behavior problems. Whereas greater foster caregiver commitment was associated with higher levels of adjustment for children in foster families (kin and non-kin), this was not the case in foster-to-adopt families. Finally, the associations between foster child behavior problems and history of maltreatment and placement related-risk conditions fell below significance after considering child age and quality of interaction with the foster caregiver. Findings underscore the crucial contribution of the foster caregiver-child relationship to fostering child adjustment and, thereby, have important implications for clinical services offered to this population.

    The primary objective of this study was to determine factors in the clinic setting associated with concussion-related problems in the school setting. A total of 91 student athletes, 13 to 19 years old, completed the SCAT2 and computerized testing during their initial visit to the clinic. During a follow-up telephone interview, one-third reported problems with return to school. The presence of problems reported in school was associated with severity of concussion as represented by recovery time and the overall number of symptoms at the first clinic visit. Gender, age, and previous concussions were not associated with school problems. Athletes with computerized test scores below the ninth percentile were more likely to report school problems. The current study offers some descriptive information for clinicians and ideas for future research related to adolescent athletes with concussion and problems with return to the classroom.

    Purpose The present study aimed to determine the effect of demographic characteristics, occupation, anthropometric indices, and leisure-time physical activity levels on coronary risk and health-related quality of life among military police officers from the State of Santa Catarina, Brazil. Methods The sample included 165 military police officers who fulfilled the study’s inclusion criteria. The International Physical Activity Questionnaire and the Short Form Health Survey were used, in addition to a spreadsheet of socio-demographic, occupational and anthropometric data. Statistical analyses were performed using descriptive analysis followed by Spearman Correlation and multiple linear regression analysis using the backward method. Results The waist-to-height ratio was identified as a risk factor low health-related quality of life. In addition, the conicity index, fat percentage, years of service in the military police, minutes of work per day and leisure-time physical activity levels were identified as risk factors for coronary disease among police officers. Conclusions These findings suggest that the Military Police Department should adopt an institutional policy that allows police officers to practice regular physical activity in order to maintain and improve their physical fitness, health, job performance, and quality of life.

    Anxiety sensitivity (AS)--fear of anxiety-related experiences--has been implicated in smoking motivation and maintenance. In a cross-sectional design, we examined AS facets (physical, cognitive, and social concerns) in relation to tobacco use, abstinence-related problems, and cognitions in 473 treatment-seeking smokers. After controlling for sex, race, age, educational attainment, hypertension status, and neuroticism, linear regression models indicated that AS physical and cognitive concerns were associated with tobacco dependence severity (β=.13-.14, p<.01), particularly the severity of persistent smoking regardless of context or time of day (β=.14-.17, p<.01). All three AS facets were related to more severe problems during past quit attempts (β=.23-.27, p<.001). AS cognitive and social concerns were related to negative affect reduction smoking motives (β=.14, p<.01), but only the social concerns aspect of AS was related to pleasurable relaxation smoking motives and positive and negative reinforcement-related smoking outcome expectancies (β=.14-.17, p<.01). These data suggest that AS physical and cognitive concerns are associated with negative reinforcement-related smoking variables (e.g., abstinence-related problems), whereas the social concerns aspect of AS is associated with positive and negative reinforcement-related smoking variables. Together with past findings, current findings can usefully guide AS-oriented smoking cessation treatment development and refinement. PMID:26802790

    There is a lack of longitudinal data on the effect of osteoradionecrosis (ORN) on health-related quality of life (HRQoL). We report data on HRQoL across groups of patients with ORN at different stages of disease and reconstruction. We identified 71 patients treated for ORN of the mandible, and cross-referenced the data with their medical records. They were divided into 4 groups according to the Notani classification and patients who did not have ORN were used for comparison. Patients with ORN reported the most pain, and rates were relatively high for problems concerning appearance, activity, recreation, swallowing, and chewing. There were significant differences for pain, appearance, swallowing, and chewing between patients who had ORN and those who did not and had not had radiotherapy. On the University of Washington quality of life questionnaire (UWQoL), patients with ORN reported similar levels of morbidity to those who had had radiotherapy but did not have ORN, particularly on the physical and social-emotional subscales. Those with grade III ORN were particularly affected, and the UWQoL scores after mandibular resection and reconstruction were disappointing. HRQoL after composite resection for Notani grade III disease is relatively poor. In patients whose symptoms can be managed without an operation, it seems appropriate to defer resection and reconstruction until there is an appreciable drop in the quality of life, and pain is difficult to control.

    Workers' working conditions, work-related health problems and sickness absence are interdependent factors. Both workers' health problems and their absence are adverse events which generate significant costs for both Poland's Social Insurance Institution (ZUS) and employers. Despite the related burdens, it is difficult to assess the number of workers who experience work-related health problems, to indicate the share of those workers who have been unfit for work owing to such disorders and to indicate the types of workers' disorders which are caused by factors the workers are exposed to in the working environment. This article presents the findings of surveys carried out in selected production and service-providing companies, assessing the scale and nature of work-related health problems and their links with workers' sickness absence.

    2012-01-01

    Background A systematic literature review was conducted to (a) identify the most frequently used health-related quality of life (HRQOL) models and (b) critique those models. Methods Online search engines were queried using pre-determined inclusion and exclusion criteria. We reviewed titles, abstracts, and then full-text articles for their relevance to this review. Then the most commonly used models were identified, reviewed in tables, and critiqued using published criteria. Results Of 1,602 titles identified, 100 articles from 21 countries met the inclusion criteria. The most frequently used HRQOL models were: Wilson and Cleary (16%), Ferrans and colleagues (4%), or World Health Organization (WHO) (5%). Ferrans and colleagues’ model was a revision of Wilson and Cleary’s model and appeared to have the greatest potential to guide future HRQOL research and practice. Conclusions Recommendations are for researchers to use one of the three common HRQOL models unless there are compelling and clearly delineated reasons for creating new models. Disease-specific models can be derived from one of the three commonly used HRQOL models. We recommend Ferrans and colleagues’ model because they added individual and environmental characteristics to the popular Wilson and Cleary model to better explain HRQOL. Using a common HRQOL model across studies will promote a coherent body of evidence that will more quickly advance the science in the area of HRQOL. PMID:23158687

    Background Women facing social and economic disadvantage in stressed communities of developing countries are at greater risk due to health problems. This paper investigates the relationships between structural, health and psychosocial predictors among women in mining and agricultural communities. This paper is a report of a study of the predictors of the health-related quality of life among Indian women in mining and agricultural communities. Methods A descriptive cross-sectional research design was used. The instruments used are SF-36 Health Survey and Coping Strategy Checklist. ANOVA, MANOVA and GLM were used in the analysis. The study was conducted between January-September 2008 with randomly selected women in a mining (145) and an agricultural community (133) in India. Results Women in the agricultural community had significantly increased Physical Health, Mental Health and SF36 scores compared with those in the mining community. Years of stay, education and employment were significant predictors among women in the agricultural community. 39% (33%) and 40% (26%) of the variance in Physical and Mental health respectively among women in agricultural and mining communities are predicted by the structural, health and psychosocial variables. Conclusion Perceived health status should be recognised as an important assessment of Physical and Mental Health among women in rural stressed communities. Cognitive, emotional and behavioural coping strategies are significant predictors of health related quality of life. Implications. Nurses should use the SF-36 as a diagnostic tool for assessing health related quality of life among women and discuss coping strategies, so that these can target women’s adaptive behaviour. This should be an essential part of the nursing process for facilitating adaptive process for improved health related quality of life. PMID:23336256

    Background: Nurses as the largest group of health care providers should enjoy a satisfactory quality of working life to be able to provide quality care to their patients. Therefore, attention should be paid to the nurses’ working life. Objectives: This study aimed to investigate the quality of nurses' working life in Kashans' hospitals during 2012. Materials and Methods: This cross-sectional study was conducted on 200 nurses during 2012. The data-gathering instrument consisted of two parts. The first part consisted of questions on demographic information and the second part was the Walton’s quality of work life questionnaire. Data were analyzed using the SPSS software. For statistical analysis T test and one way ANOVA were used. Results: The results of the study showed that 60% of nurses reported that they had moderate level of quality of working life while 37.1% and 2% had undesirable and good quality of working life, respectively. Nurses with associate degrees reported a better quality of working life than others. A significant relationship was found between variables such as education level, work experience, and type of hospital with quality of working life score (P < 0.05). No significant differences were observed between quality of working life score of nurses with employment status (P = 0.061), salary (P = 0.052), age, gender and marital status (P > 0.05). Conclusions: Nurses' quality of work life was at the moderate level. As quality of work life has an important impact on attracting and retaining employees, it is necessary to pay more attention to the nurses’ quality of work life and its affecting factors.

    Total hip arthroplasty reduces pain and restores physical function in patients with hip joint problems. This study examined lifestyle and health-related quality of life before and after total hip arthroplasty in Japanese and Chinese patients. Two hospitals in China recruited 120 patients and 120 Japanese patients matched by age and operative status were drawn from a prospective cohort database. Oxford Hip Score, EuroQol, and characteristics of Asian lifestyle and attitudes toward the operation were assessed. There were no differences between patients from the two countries in quality-of-life-scale scores: postoperative patients had significantly better quality-of-life scores than preoperative patients in both countries. In China, patients who reported that living at home was inconvenient had significantly worse Oxford Hip Scores than those who did not. Mean scores for anxiety items concerning possible dislocation and durability of the implant were significantly higher in Japanese than in Chinese subjects. Our findings suggest that providing information about housing conditions and lifestyles would result in improved quality of life and reduced anxiety in patients with implanted joints.

    The aim of this study was to describe the Quality of Life and pain coping strategies of school children in relation to headache severity. We conducted a cross-sectional study in 2815 children between the age of 9 and 17 years, who filled out Waters' Headache Questionnaire (WHQ), the Paediatric Pain Assessment Tool (PPAT), the Quality of Life Headache in Youth (QLH-Y) questionnaire and the Pain Coping Questionnaire (PCQ) in the class-room setting. Weekly headaches were reported by 22% of the sample. Low, medium, and high headache severity groups were constructed, based on headache frequency, duration and intensity criteria. Results show that children with the highest headache severity report the lowest Quality of Life in general and the lowest Quality of Health, as well as the most problems with regard to physical functioning, impact of headache on daily and leisure activities, physical symptoms other than headache, and social functioning at home. With regard to using pain coping strategies, children with the most severe headaches seek more social support, they internalize and externalize more, they use less behavioural and cognitive distraction techniques, and seek information less.

    Increasing rates of heavy episodic drinking (HED; four or more drinks in one sitting) and alcohol use disorders among young adult Asian American women signify the need to identify the risk and protective factors for HED and alcohol-related problems in this demographic. Multidimensional feminine norms, or the beliefs and expectations of what it means to be a woman, are theoretically relevant factors that may help elucidate within-group variability in HED and alcohol-related problems. The present study examined associations between nine salient feminine norms, HED, and alcohol-related problems among 398 second-generation Asian American college women. Our findings reveal that certain feminine norms are protective of HED and alcohol-related problems, while others are risk factors, even when controlling for well-established correlates of HED and alcohol-related problems, such as perceived peer drinking norms. The results elucidate the importance of multidimensional feminine norms and their relationship to HED and alcohol-related problems among the increasingly at-risk group, Asian American college women.

    The issue of drug related problems (DRPs) has been known and dealt with in many studies for a long time. It is primarily due to the fact that drug-related problems have the potential to increase patients morbidity and mortality in particular. The issue of identifying and solving drug-related problems in the area of pharmacotherapy by community pharmacists in the Slovak Republic, unlike in other European countries such as the Netherlands and the United Kingdom, is still at the beginning and gradually developing. The aim of the survey was to obtain information from pharmacy practice concerning the current state and possible solutions of potential risks of medicines in the form of drug-related problems of patients from community pharmacists point of view as well as to find out the role and status of community pharmacists in identifying and solving drug-related problems. A questionnaire survey using a sample of 237 respondents, its statistical processing and evaluation revealed the drug-related problems frequency met at their patients (the most common types of DRPs, their causes and subsequent intervention), as well as the opinions of community pharmacists on their current possibilities of (legislative, material, personnel, time) solving and risk-rating therapies for patients.

    2012-01-01

    Background Being born with low birth weight may have an impact on different aspects of mental health, psychosocial functioning and well-being; however results from studies in young adulthood have so far yielded mixed findings. The aim of this study was to assess the long-term impact in young adulthood on self-reported mental health, health-related quality of life, self-esteem and social relations by investigating differences between two low birth weight groups and a control group. Methods In a follow-up at 20 years of age, 43 preterm VLBW (birth weight ≤ 1500 g), 55 term SGA (birth weight < 10th percentile) and 74 control subjects completed the Adult Self-Report (ASR) of the Achenbach System of Empirically Based Assessment, the Adult Autism Spectrum Quotient (AQ), the Short Form 36 Health Survey, the Self-Perception Profile for Adolescents-Revised, and the Wechsler Adult Intelligent Scale III assessment. Results The VLBW and SGA groups reported significantly more mental health problems than controls. The VLBW group predominantly had internalizing problems, and the non-significant association with ASR Total score was reduced by the Intelligence Quotient (IQ). The SGA group had increased scores on both internalizing and externalizing problems, and the association with ASR Total score remained significant after adjusting for IQ in this group. Both low birth weight groups reported less interaction with friends and lower quality of life related to mental health domains than controls. Self-esteem scores were lower than in the control group for athletic competence (VLBW) and social acceptance (SGA). Conclusion Our findings suggest that self-reported mental health and well-being in young adulthood may be adversely affected by low birth weight, irrespective of whether this is the result of premature birth or being born SGA at term.

    The current study seeks to evaluate relationships between drinking motives and alcohol-related ambivalence in the prediction of problem drinking. We expected that: 1) main effects would emerge such that alcohol-related ambivalence would be positively associated with peak drinking and problems; drinking motives would be positively associated with drinking and problems, and 2) interactions would emerge between motives and ambivalence in predicting problematic drinking such that drinking motives would be positively associated with peak drinking and problems, especially among those high in ambivalence over drinking. Six hundred sixty-nine undergraduate students (mean age = 22.95, SD = 5.47, 82.22% female) completed study materials. Results showed that consistent with expectations, ambivalence was positively associated with peak drinking and problems. Further, consistent with expectations, drinking motives were positively associated with peak drinking and problems. Additionally, ambivalence was positively associated with drinking motives. Significant interactions emerged between drinking motives (social and coping) and ambivalence when predicting peak drinking and alcohol-related problems. These findings highlight the importance of considering motives in the relationship between ambivalence and drinking. Clinical implications include the need for tailoring interventions to target individual difference factors that increase risk for heavy drinking and associated problems. This is especially important among college students who may be at risk for problematic behavior. PMID:24094922

  4. Health-related quality of life in migrant preschool children

    PubMed Central

    2013-01-01

    Background Minority groups have a lower health-related quality of life (HRQOL), but there is little information if this finding also applies to children. In this study, we compared HRQOL between young children with and without migrant parents. Methods Two cross-sectional studies of culturally diverse preschool populations in Switzerland: Ballabeina (40 preschools, 258 girls and 232 boys aged 4 to 6 years) and Youp’là Bouge (58 child care centers, 453 girls and 522 boys aged 2 to 4 years). Most children were born in Switzerland (Ballabeina: 92.3%; Youp’là Bouge: 93.7%). Number of migrant parents was considered as the main exposure. HRQOL was measured using the 23-item Pediatric Quality of Life Inventory. Results Children of migrant parents had a significantly lower HRQOL total score (mean ± SD, Ballabeina: 84.2 ± 9.1; 82.7 ± 9.6 and 81.7 ± 11.7 for children with none, one or two migrant parents, respectively; Youp’là Bouge: 83.8 ± 8.6; 82.9 ± 9.5; 80.7 ± 11.7, all p < 0.05). Similar results were found in Ballabeina and Youp’là Bouge for social, school and physical functioning (all p < 0.05), but not for emotional functioning. The differences in HRQOL measures were partly mediated by children’s place of birth, parental education, paternal occupational level, children’s BMI, screen time and physical activity in one study (Ballabeina), but not in the other (Youp’là Bouge). Conclusion In preschoolers, children of migrant parents have lower HRQOL than children of non-migrant parents. These differences are only partly mediated by other sociocultural characteristics or lifestyle behavior. These families may need assistance to prevent further inequalities. PMID:23617686

  5. Physical activity and health related quality of life

    PubMed Central

    2012-01-01

    Background Research on the relationship between Health Related Quality of Life (HRQoL) and physical activity (PA), to date, have rarely investigated how this relationship differ across objective and subjective measures of PA. The aim of this paper is to explore the relationship between HRQoL and PA, and examine how this relationship differs across objective and subjective measures of PA, within the context of a large representative national survey from England. Methods Using a sample of 5,537 adults (40–60 years) from a representative national survey in England (Health Survey for England 2008), Tobit regressions with upper censoring was employed to model the association between HRQoL and objective, and subjective measures of PA controlling for potential confounders. We tested the robustness of this relationship across specific types of PA. HRQoL was assessed using the summary measure of health state utility value derived from the EuroQol-5 Dimensions (EQ-5D) whilst PA was assessed via subjective measure (questionnaire) and objective measure (accelerometer- actigraph model GT1M). The actigraph was worn (at the waist) for 7 days (during waking hours) by a randomly selected sub-sample of the HSE 2008 respondents (4,507 adults – 16 plus years), with a valid day constituting 10 hours. Analysis was conducted in 2010. Results Findings suggest that higher levels of PA are associated with better HRQoL (regression coefficient: 0.026 to 0.072). This relationship is consistent across different measures and types of PA although differences in the magnitude of HRQoL benefit associated with objective and subjective (regression coefficient: 0.047) measures of PA are noticeable, with the former measure being associated with a relatively better HRQoL (regression coefficient: 0.072). Conclusion Higher levels of PA are associated with better HRQoL. Using an objective measure of PA compared with subjective shows a relatively better HRQoL. PMID:22871153

    The main motivating factor driving this research is to find differences between the automotive related companies in Malaysia and Indonesia with regard to quality engineering (QE) implementation. A comparative study between Malaysia and Indonesia provides the opportunity to gain perspective and thorough understanding of the similarities and differences on the critical factors for successful QE practices in the context of both these countries. Face to face interviews are used to compare the QE practices in two automotive companies in Malaysia and Indonesia, respectively. The findings of study showed that both countries have clear quality objectives to achieving zero defects in processes and products and total customer satisfaction. Top and middle management in both countries were found to be directly involved in quality improvement on the shop floor to provide On-The-Job training and actively encourage team members to perform quality problem solving through the formation of quality control circles (QCC) particularly in Indonesia automotive industry. In Malaysia automotive industry, the implementation was not fully effective, but they have started to cultivate those values in the daily execution. Based on the case study results and analysis, the researcher has provided suggestions for both countries as an improvement plan for successful QE implementation. These recommendations will allow management to implement appropriate strategies for better QE implementation which hopefully can improve company's performance and ultimately the making the automotive industry in both countries to reach world class quality. It is strongly believed that the findings of this study can help Malaysia and Indonesia automotive industries in their efforts to become more effective and competitive.

    This study examined the relations between facial attractiveness, peer victimization, and internalizing problems in early adolescence. We hypothesized that experiences of peer victimization would partially mediate the relationship between attractiveness and internalizing problems. Ratings of attractiveness were obtained from standardized photographs of participants (93 girls, 82 boys). Teachers provided information regarding peer victimization experiences in sixth grade, and seventh grade teachers assessed internalizing problems. Attractiveness was negatively correlated with victimization and internalizing problems. Experiences of peer victimization were positively correlated with internalizing problems. Structural equation modeling provided support for the hypothesized model of peer victimization partially mediating the relationship between attractiveness and internalizing problems. Implications for intervention programs and future research directions are discussed. PMID:21984861

    2016-01-01

    Objectives: Two-thirds of adolescents with chronic musculoskeletal pain report a concurrent sleep problem. Both musculoskeletal pain and sleep problems can have deleterious effects on physiological and psychological well-being. We explored the prevalence of sleep problems and musculoskeletal pain, using data on 3568 adolescents from the Avon Longitudinal Study of Children. Materials and Methods: A comprehensive battery of questionnaires was administered to derive clinical phenotypes of musculoskeletal pain. Adolescents with single symptoms were compared with those reporting both musculoskeletal pain and sleep problems. Linear and logistic regression analyses were used to compare groups on pain-related variables and psychological complaints. The association between sociodemographic variables and comorbid musculoskeletal pain and sleep problems was assessed using logistic regression. Results: Over half the sample was female (n=2076, 58.2%) and the majority of European ancestry (n=3174, 97.7%). Only 5.5% (n=196) of participants were identified as having a pain condition, while 21.2% (n=749) reported a significant sleep problem, and 2.8% (n=99) reported comorbid musculoskeletal pain and sleep problems. Adolescents with comorbid problems experienced greater pain intensity and pain-related anxiety. Other psychological complaints were also higher in those who experienced concurrent problems, including depression, fatigue, concentration, and overall severity of psychological symptoms. Discussion: Comorbid sleep and pain problems were associated with a higher incidence of pain-related and psychological symptoms. Sleep problems may therefore be an important modifiable risk factor for alleviating distress in adolescents with musculoskeletal pain. PMID:25974623

    Background Employee job satisfaction and its relationship with health and quality of life has been an issue of major concern over the past decades. Nurses experience difficult working conditions that affect their job satisfaction, health, and quality of life. Methods A cross-sectional study was undertaken in three general hospitals and their respective health centers. Stratified random sampling by level of education was used, and 508 nurses and nursing assistants were included. A self-administered anonymous questionnaire, which included the Measure of Job Satisfaction, the 36-item Short Form Health Survey, as well as demographic details, education, and work conditions data, was used. Results Greek nurses were found to be dissatisfied with their job according to the total score of the job satisfaction scale, although personal satisfaction and satisfaction with support had had higher scores. Their general health was reported as average, because of physical and mental health problems, low vitality, low energy, and increased physical pain. Multivariate linear regression analysis revealed that males and those wishing to stay in the job had higher physical and mental health. Increased job satisfaction was related to increased physical and mental health. Conclusion Although Greek nurses are not satisfied with their work, those with high levels of job satisfaction had better health-related quality of life. The findings suggest that improvement of the work environment would contribute to a healthier and more satisfied nursing workforce. PMID:26929845

    1992-10-01

    Heart transplantation has become an accepted therapy for patients suffering from terminal heart disease for whom neither standard forms of medication nor the usual surgery are of any benefit. Although results regarding postoperative quantity and quality of life are encouraging, it must not be overlooked that the patient and his family face, and have to overcome, profound psychosocial problems. The main stressors were identified in interviews with 47 heart transplant patients. The main preoperative problems were: the way of being informed about the diagnosis, the waiting period for transplantation, anguishing doubts about the decision to have a transplant, being a body without heart ('zombie'), guilt and shame regarding the donor, the reactions of others. Postoperatively the patients have to cope with: re-entering social systems, reactions of friends, neighbours and colleagues, rejection episodes, death of a fellow patient, the need to redesign family life. All the problems reported by the patients interviewed are discussed regarding their psychosocial implications, and hints are given on how to minimize them. PMID:1299462

    This report examined gender differences in behavior problems and prediction of their changes from 2½ to 3½ years from mothering qualities among 209 low-income Hispanic children. Externalizing behaviors declined over this time somewhat more for girls than for boys. Fewer externalizing behavior problems at age 3½ were correlated with more supportive and less intrusive mothering at 2½ but only for boys, and increases in externalizing behavior among boys were uniquely predicted by greater maternal intrusiveness. Implications for understanding parental control factors among Hispanic families are discussed. PMID:27010364

    Falls and fall injuries among the elderly population are common, since ageing is a risk factor of falling. Today, this is a major problem because the ageing population is increasing. There are predictive factors of falling and visual impairment is one of them. Usually, only visual acuity is considered when measuring visual impairment, and nothing regarding a person's functional visual ability is taken into account. Therefore, the aim of this study was to assess the perceived vision-related quality of life among the community living elderly using the 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25) and to investigate whether there was any association among vision-related quality of life and falls. There were 212 randomly selected elderly people participating in the study. Our study indicated that the participants had an impaired perceived vision-related health status. General health was the only NEI VFQ-25 variable significantly associated with falls in both men and women. However, among men, near and distance activities, vision-specific social functioning, role difficulties and dependency, color and peripheral vision were related to falls.

    We describe two relatively simple reductions to order 6 for the planar general three-body problem. We also show that this reduction leads to the distinction between two types of periodic solutions: absolute or relative periodic solutions. An algorithm for obtaining relative periodic solutions using heliocentric coordinates is then described. It is concluded from the periodicity conditions that relative periodic solutions must form families with a single parameter. Finally, two such families have been obtained numerically and are described in some detail.

    The effect of prenatal cocaine exposure (PCE) on externalizing behavior and substance use related problems at 15 years of age was examined. Participants consisted of 358 adolescents (183 PCE, 175 non-cocaine exposed (NCE)), primarily African-American and of low socioeconomic status, prospectively enrolled in a longitudinal study from birth. Regression analyses indicated that the amount of PCE was associated with higher externalizing behavioral problems (β=.15, p=.02). Adolescents with PCE were also 2.8 times (95% CI=1.38–5.56) more likely to have substance use related problems than their NCE counterparts. No differences between PCE adolescents in non-kinship adoptive or foster care (n=44) and PCE adolescents in maternal/relative care (n=139) were found in externalizing behavior or in the likelihood of substance use related problems. Findings demonstrate teratologic effects of PCE persisting into adolescence. PCE is a reliable marker for the potential development of problem behaviors in adolescence, including substance use related problems. PMID:24636687

    Approximately 43% of children in the United States (32 million) are currently living with at least 1 of 20 common chronic childhood illnesses. The most common chronic childhood illnesses are asthma, cystic fibrosis, diabetes, obesity, malnutrition, developmental disabilities, cerebral palsy, consequences of low birthweight, and mental illness. For all chronically ill pediatric populations, the outcome of health-related quality of life (HRQOL) is particularly important because many of these children have not and will not be cured, and will continue to manage their chronic illness into adulthood. Advances in biomedical science and technology continue to improve efficacy of treatments and care for chronically ill children, adolescents, and their families, which highlight the importance measurement of HRQOL as a treatment and health status outcome. The construct of HRQOL is subjective, multidimensional, dynamic, and unique to each individual. It includes aspects of physical, psychological, social function, and goal attainment. Outcomes of HRQOL now include the financial implications for these children and their families, as well as financial and organizational consequences for healthcare planning and delivery of services.This article reviews the importance of HRQOL as a health outcome for chronically ill children. A historical overview and synthesis of the conceptualization and measurement of HRQOL for the chronically ill pediatric population is provided. Current research investigations that have measured health outcomes using individual scales tailored to children's specific symptoms health outcomes, such as PROMIS®-Patient Reported Outcomes Measurement Information System-are reviewed. The clinical applications of HRQOL outcomes research include facilitation of patient-healthcare provider communication, improved patient satisfaction, identification of hidden morbidities, a positive impact on clinical decision making, and improvement of patient outcomes over time

    Maintained by the perseverance of the management, the process of institutional quality rests on three pillars: the organization of quality assurance, process control, and a system of documentation. A methodological and organizational description of this system of documentation (the kinds of documents and their classification, the identification, content, and management of documents from their creation to their placement in archives or destruction) is presented. Many of the processes of institutional quality which occur in a blood bank can also be reproduced in health care institutions. PMID:9453806

    As the fields of quality assessment and improvement become integral parts of medical practice, the roles of National Medical Associations, and other physician organizations in these endeavors have undergone major changes in scope and intensity as well. The survey based report in this journal by Levi et al. suggests some major overall trends but also notes wide variation from country to country. In this commentary, we touch on some likely reasons for the variation seen in the focus of physician organization participation in quality activities, and offer some suggestions for why expanded involvement by physician organizations may be critical to quality efforts going forward.

    Background Working in humanitarian crisis situations is dangerous. National humanitarian staff in particular face the risk of primary and secondary trauma exposure which can lead to mental health problems. Despite this, research on the mental health of national staff is scarce, and a systematic analysis of up-to-date findings has not been undertaken yet. Objective This article reviews the available literature on trauma-related mental health problems among national humanitarian staff. It focuses on the prevalence of selected mental health problems in relation to reference groups; sex and/or gender as predictive factors of mental health problems; and the influence of organization types on mental health problems. Method Three databases were systematically searched for relevant studies published in the English language in peer-reviewed journals. Results Fourteen articles matched the inclusion criteria. Findings suggest that national staff experience mental health problems and the prevalence of posttraumatic stress disorder, depression, and anxiety among this occupation group is mostly similar to or higher than among reference groups. Research on both substance use disorder and suicidal behavior among national staff is particularly scarce. The relation between sex and/or gender and mental health problems among national staff appears to be complex, and organizational staff support seems to be an important determinant for mental health. Conclusion All findings call for increased attention from the humanitarian community and further research on the topic. PMID:26589256

    2014-01-01

    Background Parental monitoring has been identified as a protective factor for adolescent drinking, while depressed mood, peer substance use and peer tolerance of substance use have been identified as risk factors. The purpose of this study was to test the association between depressed mood and alcohol-related problems in adolescents, and to test whether parental monitoring and peer substance use/tolerance of use moderate the strength of this relationship. Methods Participants included 227 adolescents (Mage = 15.36; 51.5% female) recruited from a hospital emergency department and surrounding community who completed self-report assessments. Results Hierarchical linear regression analysis demonstrated that depressed mood was associated with more alcohol-related problems. A significant interaction between depressed mood and parental monitoring indicated a moderating effect, with high levels of depressed mood being associated with alcohol-related problems when parental monitoring was low; at low levels of depressed mood, parental monitoring was not related to alcohol-related problems. Conclusions This study highlights the protective role that parental monitoring may play in the association between depressed mood and alcohol-related problems, and suggests that parenting practices, in addition to individual counseling, should be addressed in treatment of depressed adolescents who drink.

    Deficits in emotional and behavioral regulation figure prominently in etiological models of alcohol-related problems (Baker, Piper, McCarthy, Majeskie, & Fiore, 2004; Wiers et al., 2007). This study tests a model linking poor differentiation of emotion to alcohol-related problems via urgency. The sample consisted of 102 undergraduates between the ages 18 to 24 who reported moderate to heavy alcohol consumption. As hypothesized, negative urgency mediated the relationship between negative emotion differentiation and alcohol-related problems. However, contrary to hypothesis, positive urgency was not associated with either positive emotion differentiation or alcohol-related problems and the indirect effect of positive emotion differentiation via positive urgency was not significant. Instead, positive emotion differentiation exhibited a significant direct effect on alcohol-related problems. This study provides an initial examination of connections between specificity in labeling emotions, behavioral disinhibition, and problematic alcohol use. These findings suggest poor differentiation of negative emotion may foster impulsive behavior when negatively aroused. Whereas, impulsive behavior when positively aroused may reflect heightened sensitivity to positive reinforcement, which may not be related to reflective processes underlying emotion differentiation.

    Adult patients with heart failure (HF) commonly experience depression, with morbid and mortal consequences. However, mood disorders in pediatric patients with HF are poorly understood. This study examined mood and health-related quality of life (HRQOL) in children with HF and compared them cross-sectionally with those of healthy control subjects and heart transplant (Htx) recipients with good heart function. The 62 participants in this study were divided into three groups: HF subjects (n = 15), Htx subjects (n = 23), and healthy control subjects (n = 24). The HF subjects all had chronic HF with a left ventricular ejection fraction lower than 35 %. All the participants completed the Mini-Mental State Examination (MMSE), the Childhood Depression Inventory (CDI), and the Pediatric Quality-of-Life Inventory Cardiac Module (PedsQL CM). Overall, the MMSE scores and CDI subscale scores were similar for all the groups. The HF and Htx participants scored similarly on the PedsQL CM subscales for HRQOL, treatment anxiety, perceived physical appearance, cognitive function, and communication. However, the HF group had a significantly lower HRQOL related to heart problems and treatment than the Htx group. The prevalence of depression among children with HF is not as high as reported in the adult HF literature. However, certain aspects of HRQOL experienced by pediatric HF patients still suffer, especially those related to heart problems and treatment. Health-related QOL tended to be better for the Htx participants than for the HF participants. Exploring developmental and psychosocial outcomes is critical for patients with HF, especially because it has an impact on vital developmental, academic, and social outcomes.

    It is shown that the equations of the general three-body problem take on a very symmetric form when one considers only their relative positions, rather than position vectors relative to some given coordinate system. From these equations one quickly surmises some well known classical properties of the three-body problem, such as the first integrals and the equilateral triangle solutions. Some new Lagrangians with relative coordinates are also obtained. Numerical integration of the new equations of motion is about 10% faster than with barycentric or heliocentric coordinates.

  16. Assessment of the quality of measures of child oral health-related quality of life

    PubMed Central

    2014-01-01

    Background Several measures of oral health-related quality of life have been developed for children. The most frequently used are the Child Perceptions Questionnaire (CPQ), the Child Oral Impacts on Daily Performances (C-OIDP) and the Child Oral Health Impact Profile (COHIP). The aim of this study was to assess the methodological quality of the development and testing of these three measures. Methods A systematic search strategy was used to identify eligible studies published up to December 2012, using both MEDLINE and Web of Science. Titles and abstracts were read independently by two investigators and full papers retrieved where the inclusion criteria were met. Data were extracted by two teams of two investigators using a piloted protocol. The data were used to describe the development of the measures and their use against existing criteria. The methodological quality and measurement properties of the measures were assessed using standards proposed by the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) group. Results The search strategy yielded 653 papers, of which 417 were duplicates. Following analysis of the abstracts, 119 papers met the inclusion criteria. The majority of papers reported cross-sectional studies (n = 117) with three of longitudinal design. Fifteen studies which had used the original version of the measures in their original language were included in the COSMIN analysis. The most frequently used measure was the CPQ. Reliability and construct validity appear to be adequate for all three measures. Children were not fully involved in item generation which may compromise their content validity. Internal consistency was measured using classic test theory with no evidence of modern psychometric techniques being used to test unidimensionality of the measures included in the COSMIN analysis. Conclusion The three measures evaluated appear to be able to discriminate between groups. CPQ has been most widely

    In the wild, chimpanzees (Pan troglodytes) are often faced with clumped food resources that they may know how to access but abstain from doing so due to social pressures. To better understand how social settings influence resource acquisition, we tested fifteen semi-wild chimpanzees from two social groups alone and in the presence of others. We investigated how resource acquisition was affected by relative social dominance, whether collaborative problem solving or (active or passive) sharing occurred amongst any of the dyads, and whether these outcomes were related to relationship quality as determined from six months of observational data. Results indicated that chimpanzees obtained fewer rewards when tested in the presence of others compared to when they were tested alone, and this loss tended to be greater when paired with a higher ranked individual. Individuals demonstrated behavioral inhibition; chimpanzees who showed proficient skill when alone often abstained from solving the task when in the presence of others. Finally, individuals with close social relationships spent more time together in the problem solving space, but collaboration and sharing were infrequent and sessions in which collaboration or sharing did occur contained more instances of aggression. Group living provides benefits and imposes costs, and these findings highlight that one cost of group living may be diminishing productive individual behaviors.

    Objective To compare the effect of problem solving therapy against a health-promotion intervention (dietary practices) on health-related quality of life (HRQOL) and examine if there is a differential effect on non-Latino Whites and African-Americans between the two interventions. This paper also explores participant characteristics (problem solving style and physical functioning) as potential predictors of HRQOL. Methods Secondary analysis of data from a randomized depression prevention trial involving 247 older adults (154 non-Latino Whites, 90 African-Americans, 3 Asians). Participants were randomly assigned to receive either problem solving therapy for primary care (PST-PC) or coaching in healthy dietary practices (DIET). Results Both PST-PC and DIET improved HRQOL over two years and did not differ significantly from each other. African-Americans in both conditions had greater improvements in mental health-related quality of life (MHRQOL) compared to non-Latino Whites. In addition, higher social problem solving and physical functioning were predictive of improved MHRQOL. Conclusions PST-PC and DIET have the potential to improve health-related quality of life in a culturally relevant manner. Both hold promise as effective and potentially scalable interventions that could be generalized to highly disadvantaged populations in which little attention to HRQOL has been paid. PMID:25171889

    A descriptive study in a Dermatological Research Institution in Rome, Italy, was conducted to test the feasibility and acceptability of health related quality of life (HRQoL) assessment in the daily routine. Quality of life, and psychosocial distress evaluations were obtained for each patient. Patients were invited to complete the Skindex-29, GHQ-12, and SF-36. Results were returned to the clinical staff using standardised feed-back forms with: a) "categories" of QoL scores to help interpreting Skindex-29 scores; b) "warnings" pointing out problems that patients experienced "all the time"; c) categories of GHQ-12 scores for minor psychiatric problems; d) the classical SF-36 graph depicting the patient's "QoL profile" with normative references. The clinical staff were trained, and then their attitudes and behaviours were surveyed using a standardised questionnaire. For all 170 participants enrolled (63% males, 35% age > 64 years), feed-back forms were provided within three hours from data collection. For patients with repeated hospitalisations time-trends in HRQoL measurements were also provided. The acceptability, both for patients and the clinical staff, was high but the actual impact on clinical activities was limited. The routine assessment of HRQoL in dermatology is feasible and well accepted both by patients and by the clinical staff. The application of these widely used questionnaires should be implemented in a larger scale and evaluated in different settings. PMID:16935800

  1. Rewarding results: Improving the quality of treatment for people with alcohol and drug problems.

    2004-03-01

    Substance use disorders are the nation's number one health problem, and lie at the root of many public safety and workplace issues. Improving quality of treatment is as important as improving access to treatment. Leadership for improvement must come from many sources: Congress, SAMHSA, state legislatures, state and local treatment agencies, criminal justice, welfare and other public agencies, employers and managed care organizations, providers, and community leaders. We hope that our report helps leaders see ways to improve treatment quality. Our recommendations can be summed up in a single phrase: reward results. We recognize that there are many avenues for treatment quality improvement, including training, credentialing, best practice dissemination, work force development, facility licensing standards, improvement and implementation of new models for treatment of dual diagnosis patients. We believe, however, that rewarding results is essential to motivating action for improvement. We also believe that if providers receive rewards for improved results, they will creatively open new avenues for improvement--a focus on results gives greater freedom than more detailed mandates for change. Finally, we believe that rewards for result may lead to a restructured treatment system with greater stability and correspondingly greater capacity to improve. While we have placed central emphasis on the role of institutional buyers and managers of care, we believe that the voices of patients and families must be heard. People who have progressed to the stage of recovery, and their families, often have essential insight into what did and did not work for them--their personal stories are frequently compelling and persuasive. We also believe that providers of treatment for substance use disorders are profoundly committed to serving their patients, and often have great understanding of what works. Wise managers will listen very carefully and systematically to the voices of consumers

    Background The spread of antimicrobial resistance in developing countries is associated with complex and interconnected factors, such as excessive and unnecessary prescribing of antimicrobials, increased self-prescribing by the people and poor quality of available antimicrobials. Moreover, the failure to implement infection control practices and the dearth of routine susceptibility testing and surveillance magnify the problems. This may spread the inappropriateness of prescribing, ending up with the spread of antimicrobial resistance. Objective The aim of this study was to assess antimicrobial use related problems and associated factors among patients admitted at Jimma University specialized hospital. Methods A hospital based prospective observational study design was employed at medical wards of Jimma University specialized hospital, Ethiopia. Data collected from patient medication charts and from the patients was analyzed using SPSS, version 16.0. Logistic regression was used to determine the associations between variables. Statistical significance was considered at p-value <0.05. Results Out of 152 study participants, at least one antimicrobial use problem was identified among 115(75.7%). Accordingly, additional antimicrobials were needed by 45(29.6%) of the patients, whereas they were unnecessary among 44(28.9%). Similarly, 17% of the patients were noncompliant to at least one antimicrobial therapy, while 8.6% experienced at least one type of adverse drug reaction. On the other hand, the coverage of the infectious medical condition in the national guidelines (AOR = 4.888) and the duration of hospital stay (AOR = 3.086) were the determinants of the antimicrobial use problems. Conclusion Most of the antimicrobial use problems identified were related to delay of initiation of effective antimicrobials and excessive use; use without indication or using duplicates of broad spectrum antimicrobials or use for longer duration than recommended.

    Electric power quality and reliability are becoming increasingly important as computers and microprocessors assume a larger role in commercial, health care and industrial buildings and processes. At the same time, constraints on transmission and distribution of power from central stations are making local areas vulnerable to low voltage, load addition limitations, power quality and power reliability problems. Many customers currently utilize some form of premium power in the form of standby generators and/or UPS systems. These include customers where continuous power is required because of health and safety or security reasons (hospitals, nursing homes, places of public assembly, air traffic control, military installations, telecommunications, etc.) These also include customers with industrial or commercial processes which can`t tolerance an interruption of power because of product loss or equipment damage. The paper discusses the use of the PC25 fuel cell power plant for backup and parallel power supplies for critical industrial applications. Several PC25 installations are described: the use of propane in a PC25; the use by rural cooperatives; and a demonstration of PC25 technology using landfill gas.

    Developmental psychopathologists face the difficult task of identifying the environmental conditions that may contribute to early childhood behavior problems. Highly stressed caregivers can exacerbate behavior problems, while children with behavior problems may make parenting more difficult and increase caregiver stress. Unknown is: (1) how these transactions originate, (2) whether they persist over time to contribute to the development of problem behavior and (3) what role resilience factors, such as child executive functioning, may play in mitigating the development of problem behavior. In the present study, transactional relations between caregiving stress, executive functioning, and behavior problems were examined in a sample of 1,388 children with prenatal drug exposures at three developmental time points: early childhood (birth-age 5), middle childhood (ages 6 to 9), and early adolescence (ages 10 to 13). Transactional relations differed between caregiving stress and internalizing versus externalizing behavior. Targeting executive functioning in evidence-based interventions for children with prenatal substance exposure who present with internalizing problems and treating caregiving psychopathology, depression, and parenting stress in early childhood may be particularly important for children presenting with internalizing behavior.

    Diagnostic imaging has been shifted rapidly from film to monitor diagnostic. Consequently, Japan medical imaging and radiological systems industries association (JIRA) have recommended methods of quality control (QC) for medical imaging display systems. However, in spite of its need by majority of people, executing rate is low. The purpose of this study was to validate the problem including check items about QC for medical imaging display systems. We performed acceptance test of medical imaging display monitors based on Japanese engineering standards of radiological apparatus (JESRA) X-0093*A-2005 to 2009, and performed constancy test based on JESRA X-0093*A-2010 from 2010 to 2012. Furthermore, we investigated the cause of trouble and repaired number. Medical imaging display monitors had 23 inappropriate monitors about visual estimation, and all these monitors were not criteria of JESRA about luminance uniformity. Max luminance was significantly lower year-by-year about measurement estimation, and the 29 monitors did not meet the criteria of JESRA about luminance deviation. Repaired number of medical imaging display monitors had 25, and the cause was failure liquid crystal panel. We suggested the problems about medical imaging display systems.

  10. Classical Zero-Point Radiation and Relativity: The Problem of Atomic Collapse Revisited

    2016-07-01

    The physicists of the early twentieth century were unaware of two aspects which are vital to understanding some aspects of modern physics within classical theory. The two aspects are: (1) the presence of classical electromagnetic zero-point radiation, and (2) the importance of special relativity. In classes in modern physics today, the problem of atomic collapse is still mentioned in the historical context of the early twentieth century. However, the classical problem of atomic collapse is currently being treated in the presence of classical zero-point radiation where the problem has been transformed. The presence of classical zero-point radiation indeed keeps the electron from falling into the Coulomb potential center. However, the old collapse problem has been replaced by a new problem where the zero-point radiation may give too much energy to the electron so as to cause "self-ionization." Special relativity may play a role in understanding this modern variation on the atomic collapse problem, just as relativity has proved crucial for a classical understanding of blackbody radiation.

    Emotional Overinvolvement (EOI) in parents’ Five Minute Speech Samples (FMSS; Magaña-Amato, 1993) is thought to measure overconcern and enmeshment with one’s child. Although related to maladaptive outcomes in studies of adult children, FMSS-EOI evidences varied relations with behavior problems in studies with young children. These mixed findings may indicate that certain FMSS-EOI criteria reflect inappropriate and excessive involvement with adult children, but do not indicate maladaptive processes when parenting younger children. Thus, this study evaluated relations of each FMSS-EOI criterion with changes in child behavior problems from preschool to first grade in a community sample of 223 child-mother dyads (47.98% female; Mage_W1 = 49.08 months; 56.50% Hispanic/Latina). Maternal FMSS-EOI ratings were obtained at wave 1, and independent examiners rated child externalizing and internalizing behavior problems at wave 1 and two years later. Path analyses indicated that both the Self-Sacrifice/Overprotection (SSOP) and Statements of Attitude (SOAs) FMSS-EOI criteria predicted increased externalizing problems. In contrast, Excessive Detail and Exaggerated Praise were not related to child externalizing behavior problems, and Emotional Display was not evident in this sample. None of the FMSS-EOI criteria evidenced significant relations with internalizing behavior problems. Multigroup comparisons indicated that the effect of SOAs on externalizing behavior problems was significant for boys but not for girls, and there were no significant group differences by race/ethnicity. These findings point to the salience of SSOP and SOAs for understanding the developmental significance of EOI in early development. PMID:26147935

The aim of our research was to determine which biomechanical (temporal, kinematic and dynamic) characteristics of landing best predict the quality of landing. Twelve male gymnasts performed a stretched forward and backward salto; also with 1/2, 1/1 and 3/2 turns. Stepwise multiple regression extracted five predictors which explained 51.5% of landing quality variance. All predictors were defining asymmetries between legs (velocities, angles). To avoid asymmetric landings, gymnasts need to develop enough height; they need higher angular momentum around the transverse and longitudinal axis and they need to better control angular velocity in the longitudinal axis.

    This study used for the first time event-related potentials (ERPs) to examine the well-known arithmetic problem size effect in children. The electrophysiological correlates of this problem size effect have been well documented in adults, but such information in children is lacking. In the present study, 22 typically developing 12-year-olds were asked to solve single-digit addition problems of small (sum ≤ 10) and large problem size (sum > 10) and to speak the solution into a voice key while ERPs were recorded. Children displayed similar early and late components compared to previous adult studies on the problem size effect. There was no effect of problem size on the early components P1, N1, and P2. The peak amplitude of the N2 component showed more negative potentials on left and right anterior electrodes for large additions compared to small additions, which might reflect differences in attentional and working memory resources between large and small problems. The mean amplitude of the late positivity component which follows the N2, was significantly larger for large than for small additions at right parieto-occipital electrodes, in line with previous adult data. The ERPs of the problem size effect during arithmetic might be a useful neural marker for future studies on fact retrieval impairments in children with mathematical difficulties. PMID:25309405

    There is growing agreement among experts that an obesogenic environment, which encourage excess food intake and idealizes thinness, plays a crucial role in the epidemic of childhood obesity and eating disorders. Because parents provide a child's contextual environment, they should be considered key players in interventions aimed at preventing or treating weight-related problems. Parenting style and feeding style are crucial factors in fostering healthy lifestyle and awareness of internal hunger and satiety cues and de-emphasizing thinness. Effective interventions for prevention and treatment of weight-related problems should be approached from a health-centered rather than a weight-centered perspective, with the parents as central agents of change. This paper reviews the environmental risk factors and parents' role in the prevention and treatment of children's weight-related problems.

    Traumatic brain injury is (TBI) a leading cause of morbidity and mortality in youth. Adult survivors of a severe pediatric TBI are vulnerable to global impairments, including greater employment difficulties, poor quality of life (HRQoL) and increased risk of mental health problems. When estimating the health related quality of life in adolescents, the presence of anxiety and depression and the quality of social relationships are important considerations, because adolescents are entrenched in social development during this phase of maturation. The influence of anxiety, depression and loneliness on health related quality of life in adolescent survivors of TBI has not been documented. This pilot study aimed to identify and measure the relationship between anxiety, depression and loneliness and perceived health related quality of life in adolescent survivors of a TBI. Method: mixed method/cohort pilot study (11 adolescents, mild to severe TBI; 9 parents), using self-report and proxy-report measures of anxiety, depression, health related quality of life, loneliness and clinical psychiatric interviews (adolescent only). Results: Self-reported depression was significantly correlated with self-reported HRQoL (rs [11] = −0.88, p<0.001). Age at injury was significantly correlated with self-reported HRQoL (rs [11] = −0.68, p = 0.02). Self-reported depression predicted self-reported HRQoL (R2 = 0.79, F [1, 10] = 33.48, p<0.001), but age at injury did not (R2 = 0.19, F [1, 10] = 2.09, p = 0.18). Conclusions: Our results suggest that depression is a predictor of health related quality of life in youth post-TBI. The possibility of using targeted assessment and therapy for depression post-TBI to improve health related quality of life should be explored. PMID:25010719

Investigation of symptom clusters indicated that reexperiencing symptoms were related to trouble initiating and maintaining sleep and nightmares, while hyperarousal symptoms were related to trouble maintaining sleep and nightmares. Findings partially support both reexperiencing and hyperarousal-based models of the relation between sleep and posttraumatic stress.

    An accident is a work-related event caused by an external factor. Therefore, myocardial infarction is also considered, in specific conditions, as a work-related accident. The aim of this study was to present the cause-effect relationship between myocardial infarction and working conditions in the context of a work-related accident characterized by: urgency of event, external factor and relation with working conditions. The attitude of the Supreme Court to the question of certification, highlighting the key issues and facilitating the understanding of the problem and opinions of legal experts on this matter is also discussed. Myocardial infarction as a work-related accident is an issue involving both law and medicine, particularly occupational medicine, that will have to tackle and solve this problem in its several dimensions, including periodical examinations.

    Abstract Alcohol misuse among adolescents is a common issue worldwide and is an emerging problem in China. This study aimed to investigate the prevalence of alcohol drinking and alcohol-related problems among Chinese adolescents and to explore their risk factors and connections. A cross-sectional study using an anonymous questionnaire was conducted among junior and senior high school students between 2010 and 2012. Data on self-reported alcohol use, alcohol-related problems, school factors, family factors, and psychosocial factors were collected. Descriptive analyses were made of the proportions of sociodemographics, family, school, and psychosocial factors. Multilevel logistic regression models were conducted to analyze the risk factors for alcohol drinking and alcohol-related problems. Of the 105,752 students who ranged in age from 9 to 21 years, the prevalence of current drinking among students was 7.3%, and 13.2% students reported having alcohol-related problems. Male students were 1.78 (95% confidence interval [CI] = 1.69–1.87) times more likely to be involved in current drinking and 1.86 (95% CI = 1.79–1.93) times more likely to have alcohol-related problems. Higher grade level students were at a higher risk of current drinking (adjusted odds ratio [AOR] = 1.09, 95% CI = 1.05–1.13) and having alcohol-related problems (AOR = 1.43, 95% CI = 1.42–1.58). Older students were more likely to report current drinking (AOR = 1.06, 95% CI = 1.04–1.17) and having alcohol-related problems (AOR = 1.83, 95% CI = 1.82–1.85). Having poor classmate relations (AOR = 1.28, 95% CI = 1.03–1.37), having poor relationships with teachers (AOR = 1.08, 95% CI = 1.00–1.16), and below average academic achievement (AOR = 1.50, 95% CI = 1.41–1.59) were positively associated with current drinking. Moreover, students with suicidal ideation were at a higher risk of current drinking (AOR = 1.70, 95% CI = 1.61–1.81) and having alcohol-related problems (AOR = 2.08, 95% CI = 1

    Swallowing difficulties in Parkinson's disease can result in decreased quality of life. The swallowing quality of life questionnaire (SWAL-QOL) is an instrument for specifically assessing quality of life with respect to swallowing, which has been little explored in patients with Parkinson's disease (PD). The goal of this study was to evaluate the quality of life with respect to swallowing in persons with PD compared to controls and at several stages of the disease using the SWAL-QOL. The experimental group was composed of 62 persons with PD at stages 1-4. Forty-one age-matched healthy subjects constituted the control group. The SWAL-QOL scores were significantly lower for the patients with PD than for the controls in all SWAL-QOL domains. Eating duration had the largest difference in score between persons with PD and the controls and the lowest mean score, followed by communication, fatigue, fear, sleep, and food selection. The scores of most domains were lower at later stages of the disease. The scores for eating duration, symptom frequency, and sleep were significantly lower at stage 4 than stages 1 and 2. In conclusion, patients with PD have significantly lower scores in all domains of the SWAL-QOL than normal controls. This means swallowing difficulties occurring in patients with PD negatively affect their QOL. Progression of the disease worsens swallowing QOL, more specifically in the domains of eating duration, symptom frequency, and sleep. This occurs mostly at later stages of the disease.

    This study aims to investigate the oral health-related quality of life (OHRQoL) in a group of removable partial denture (RPD) wearers in Shiraz (Iran), using the Persian version of the Oral Health Impact Profile (OHIP-14). Two hundred removable partial denture wearers had completed a questionnaire regarding patients' demographic characteristics and denture-related factors. In addition, the OHIP-14 questionnaire was filled out by interviewing the patients. Two measures of interpreting the OHIP-14 scales were utilised: OHIP-14 sum and OHIP-14 prevalence. The relationship of the patients' demographic characteristics and denture-related factors, with their OHRQoL was investigated. The mean OHIP-14 sum and OHIP-14 prevalence of RPD wearers were 13·80 (±10·08) and 44·5%, respectively. The most problematic aspects of OHIP-14 were physical disability and physical pain. Twenty-seven percentage and 24% of participants had reported meal interruption and eating discomfort, respectively. OHIP-14 prevalence and OHIP-14 sum were found to be significantly associated with factors representing RPD wearer's oral health such as self-reported oral health and frequency of denture cleaning. Furthermore, OHIP-14 prevalence and OHIP-14 sum were significantly associated with factors related to frequency of denture use such as hours of wearing the denture during the day and wearing the denture while eating and sleeping. Therefore, it can be concluded that the OHRQoL of the patients of the study was generally not optimal and found to be strongly associated with oral health.

    Individuals with elevated social anxiety appear particularly vulnerable to marijuana-related problems. In fact, individuals with social anxiety may be more likely to experience marijuana-related impairment than individuals with other types of anxiety. It is therefore important to determine whether constructs particularly relevant to socially anxious individuals play a role in the expression of marijuana-related problems in this vulnerable population. Given that both social avoidance and using marijuana to cope with negative affect broadly have been found to play a role in marijuana-related problems, the current study utilized a new measure designed to simultaneously assess social avoidance and using marijuana to cope in situations previously identified as anxiety-provoking among those with elevated social anxiety. The Marijuana Use to Cope with Social Anxiety Scale (MCSAS) assessed behaviors regarding 24 social situations: marijuana use to cope in social situations (MCSAS-Cope) and avoidance of social situations if marijuana was unavailable. In Study 1, we found preliminary support for the convergent and discriminant validity and internal consistency of the MCSAS scales. In Study 2, we examined if MCSAS scores were related to marijuana problems among those with (n = 44) and without (n = 44) clinically elevated social anxiety. Individuals with clinically meaningful social anxiety were more likely to use marijuana to cope in social situations and to avoid social situations if marijuana was unavailable. Of importance, MCSAS-Cope uniquely mediated the relationship between social anxiety group status and marijuana-related problems. Results highlight the importance of contextual factors in assessing marijuana-related behaviors among high-risk populations. PMID:22004129

    Objective: to investigate the correlation between disorders related to the use of alcohol and other drugs and symptoms of mental disorders, problems related to crime and violence and to age and gender. Methods: cross-sectional descriptive study carried out with 128 users of a Psychosocial Care Center for Alcohol and other Drugs, in the city of São Paulo, interviewed by means of the instrument entitled Global Appraisal of Individual Needs - Short Screener. Univariate and multiple linear regression models were used to verify the correlation between the variables. Results: using univariate regression models, internalizing and externalizing symptoms and problems related to crime/violence proved significant and were included in the multiple model, in which only the internalizing symptoms and problems related to crime and violence remained significant. Conclusions: there is a correlation between the severity of problems related to alcohol use and severity of mental health symptoms and crime and violence in the study sample. The results emphasize the need for an interdisciplinary and intersectional character of attention to users of alcohol and other drugs, since they live in a socially vulnerable environment.

    The rate of cigarette smoking is greater among persons with mental health and/or substance abuse problems. There are few population-based datasets with which to study tobacco mortality in these vulnerable groups. The Oregon Health Authority identified persons who received publicly-funded mental health or substance abuse services from January 1996 through December 2005. These cases were then matched to Oregon Vital Statistics records for all deaths (N= 148,761) in the period 1999-2005. The rate of tobacco-related death rates was higher among persons with substance abuse problems only (53.6%) and those with both substance abuse and mental health problems (46.8%), as compared to the general population (30.7%). The rate of tobacco-related deaths among persons with mental health problems (30%) was similar to that in the general population. Persons receiving substance abuse treatment alone, or receiving both substance abuse and mental health treatment, were more likely to die and more likely to die prematurely of tobacco-related causes as compared to the general population. Persons receiving mental health services alone were not more likely to die of tobacco-related causes, but tobacco-related deaths occurred earlier in this population.

    2016-06-01

    This research examined whether and how adolescents' personality traits moderate associations between psychologically controlling parenting and problem behaviors. On the basis of self-determination theory, we also examined the mediating role of psychological need frustration in the effects of psychologically controlling parenting. A cross-sectional study in two samples (N = 423 and 292; Mage = 12.43 and 15.74 years) was conducted. While in Sample 1 both mothers and adolescents provided reports of parenting and problem behavior, Sample 2 relied on adolescent-reported parenting and mother-reported problem behavior. Psychologically controlling parenting was related to internalizing and externalizing problems in both samples. Little systematic evidence was obtained for the moderating role of personality, with the exception of a moderating effect of Agreeableness. In both samples, psychological control was unrelated to externalizing problems among adolescents high on Agreeableness. Analyses of Sample 2 showed that associations between psychological control and problem behavior were mediated by psychological need frustration. Adolescent personality plays a modest role as a moderator of associations between psychologically controlling parenting and problem behavior. Frustration of adolescents' basic and universal psychological needs can account for the undermining effects of psychologically controlling parenting. Directions for future research are discussed.

    Cardiovascular disease is the main health problem in developed countries. Prevention is presented as the most effective and efficient primary care intervention, whereas cardiac rehabilitation programs are considered the most effective of secondary prevention interventions; however, these are underused. This literature review examines the effectiveness and the levels of evidence of cardiac rehabilitation programs, their components, their development and role in developed countries, applications in different fields of research and treatment, including their psychological aspects, and their application in heart failure as a paradigm of disease care under this type of intervention. It is completed by a review of the impact of such programs on measures of health-related quality of life, describing the instruments involved in studies in recent scientific literature.

    We consider a time-dependent linear diffusion equation together with a related inverse boundary value problem. The aim of the inverse problem is to determine, based on observations on the boundary, the nonhomogeneous diffusion coefficient in the interior of an object. The method in this paper relies on solving the forward problem for a whole family of diffusivities by using a spectral Galerkin method in the high-dimensional parameter domain. The evaluation of the parametric solution and its derivatives is then completely independent of spatial and temporal discretizations. In the case of a quadratic approximation for the parameter dependence and a direct solver for linear least squares problems, we show that the evaluation of the parametric solution does not increase the complexity of any linearized subproblem arising from a Gauss-Newtonian method that is used to minimize a Tikhonov functional. The feasibility of the proposed algorithm is demonstrated by diffusivity reconstructions in two and three spatial dimensions.

    Many children with autism spectrum disorders (ASD) have co-occurring feeding problems. However, there is limited knowledge about how these feeding habits are related to other behavioral characteristics ubiqitious in ASD. In a relatively large sample of 256 children with ASD, ages 2-11, we examined the relationships between feeding and mealtime behaviors and social, communication, and cognitive levels as well repetitive and ritualistic behaviors, sensory behaviors, and externalizing and internalizing behaviors. Finally, we examined whether feeding habits were predictive of nutritional adequacy. In this sample, we found strong associations between parent reported feeding habits and (1) repetitive and ritualistic behaviors, (2) sensory features, and (3) externalizing and internalizing behavior. There was a lack of association between feeding behaviors and the social and communication deficits of ASD and cognitive levels. Increases in the degree of problematic feeding behaviors predicted decrements in nutritional adequacy.

    Abstract Although trauma-associated mortality has fallen in recent decades, and medical care has continued to improve in many fields, the quality of life after experiencing polytrauma has attracted little attention in the literature. This group of patients suffer from persisting physical disabilities. Moreover, they experience long-term social, emotional, and psychological effects that limit/lower considerably their quality of life. We analyzed retrospective data on 147 polytraumatized patients by administering written questionnaires and conducting face-to-face interviews 6 ± 0.8 years after the trauma in consideration of the following validated scores: Glasgow Outcome Scale, European Quality of Life Score, Short Form-36, Trauma Outcome Profile, and Beck Depressions Inventory II. Our analysis of these results reveals that polytraumatized patients suffer from persistent pain and functional disabilities after >5 years. We also observed changes in their socioeconomic situation, as well as psychological after-effects. The rehabilitation of this particular group of patients should not only address their physical disabilities. The psychological after-effects of trauma must be acknowledged and addressed for an even longer period of time. PMID:27175646

    Background Colorectal cancer is a major public health problem in Malaysia. However, it is also one of the most treatable cancers, resulting in significant numbers of survivors. Therefore, the impact of surviving treatment for colorectal cancer on health related quality of life is important for the patients, clinicians and policy makers, and may differ in different cultures and populations. The aim of this study was to validate the Malaysian versions of the European Organization for Research and Treatment of Cancer quality of life instruments among colorectal cancers patients. Methods/design This is a cross sectional multi centre study. Three hospitals were included, the University of Malaya Medical Centre, the Universiti Kebangsaan Malaysia Medical Centre and Hospital Tuanku Jaafar Seremban. Malaysian citizens and permanent residence were studied and demographic and clinical information obtained from hospital records. The European Organization for Research and Treatment of Cancer Quality of life Core 30, colorectal cancer CR29, and the colorectal cancer liver metastasis LMC 21 were used and an observer assessment of performance obtained with the Karnofsky Performance Scale. Questionnaires were translated into three most commonly spoken languages in Malaysia (Bahasa Malaysia, Chinese and Tamil), then administered, scored and analyzed following the developers’ guidelines. Ethical approval was obtained from the participating centres. Tests of reliability and validity were performed to examine the validity of these instruments. Conclusion The result of pilot testing shows that the use of the Malaysian versions of EORTC QLQ C30, CR29 instruments is feasible in our sample of colorectal cancer patients. Instructions for completion as well as questions were well understood except the questions on the overall quality of life, overall health status and sexual activity. Thus we anticipate obtaining good psychometric properties for the instruments at the end of the study

    Although many children with burns recover well and have a satisfying quality of life after the burn, some children do not adjust as well. Health-related quality of life (HRQoL) focuses on the impact health status has on quality of life. The aim of this study was to assess HRQoL with the American Burn Association/Shriners Hospitals for Children Burn Outcomes Questionnaire (BOQ) in a nationwide Swedish sample of children with burns 0.3-9.0 years after injury. Participants were parents (n=109) of children aged up to 18 years at the time of investigation who were treated at the Linköping or Uppsala Burn Center between 2000 and 2008. The majority of children did not have limitations in physical function and they did not seem to experience much pain. However, there were indications of psychosocial problems. Parents of preschool children reported most problems with the children's behavior and family disruption, whereas parents of children aged 5-18 years reported most problems with appearance and emotional health. There were mainly burn-related variables associated with suboptimal HRQoL in children aged 5-18 years, while family-related variables did not contribute as much.

    Although many of the problems faced by the female athlete affect the male athlete as well, some occur exclusively or more commonly in women. These include spondylolisthesis, stress fractures in the pelvis and hip, and pelvic floor dysfunction. Female athletes are also more likely to have patellofemoral problems, noncontact anterior cruciate ligament tears, and bunions. For many of these conditions, the relative influences of osseous anatomy, ligamentous laxity, and the effect of sex hormones have not yet been established. There are also problems related specifically to the menstrual cycle and pregnancy. Amenorrhea is present in up to 20% of vigorously exercising women. The term "female athlete triad" has been coined to describe the complex interplay of menstrual irregularity, disordered eating, and premature osteoporosis seen in the female athlete. Many of the concerns related to exercise during pregnancy focus on the safety of the fetus rather than the athlete herself. Musculoskeletal problems in the physically active pregnant woman are related to weight gain, ligamentous relaxation, lordosis, and change in the center of gravity.

    Although alcohol use disorders (AUDs) have been associated with different aspects of disinhibited personality and antisociality, less is known about the specific relationships among different domains of disinhibited personality, antisociality, alcohol use, and alcohol problems. The current study was designed to address three goals, (i) to provide evidence of a three-factor model of disinhibited personality (comprised of impulsivity [IMP], risk taking/ low harm avoidance [RTHA], excitement seeking [ES]), (ii) to test hypotheses regarding the association between each dimension and alcohol use and problems, and (iii) to test the hypothesis that antisociality (social deviance proneness [SDP]) accounts for the direct association between IMP and alcohol problems, while ES is directly related to alcohol use. Measures of disinhibited personality IMP, RTHA, ES and SDP and alcohol use and problems were assessed in a sample of young adults (N=474), which included a high proportion of individuals with AUDs. Confirmatory factor analyses supported a three-factor model of disinhibited personality reflecting IMP, RTHA, and ES. A structural equation model (SEM) showed that IMP was specifically associated with alcohol problems, while ES was specifically associated with alcohol use. In a second SEM, SDP accounted for the majority of the variance in alcohol problems associated with IMP. The results suggest aspects of IMP associated with SDP represent a direct vulnerability to alcohol problems. In addition, the results suggest that ES reflects a specific vulnerability to excessive alcohol use, which is then associated with alcohol problems, while RTHA is not specifically associated with alcohol use or problems when controlling for IMP and ES.

    OBJECTIVES To explore central challenges with translating self-reported measurement tools for functional status and health-related quality of life (HRQOL) into ambulatory quality indicators for older people with multiple chronic conditions (MCCs). DESIGN Review. SETTING Sources including the National Quality Measures Clearinghouse and National Quality Forum were reviewed for existing ambulatory quality indicators relevant to functional status, HRQOL, and people with MCCs. PARTICIPANTS Seven informants with expertise in indicators using functional status and HRQOL. MEASUREMENTS Informant interviews were conducted to explore knowledge about these types of indicators, particularly usability and feasibility. RESULTS Nine important existing indicators were identified in the review. For process, identified indicators addressed whether providers assessed functional status; outcome indicators addressed quality of life. In interviews, informants agreed that indicators using self-reported data were important in this population. Challenges identified included concerns about usability due to inability to discriminate quality of care adequately between organizations and feasibility concerns regarding high data collection burden, with a correspondingly low response rate. Validity was also a concern because evidence is mixed that healthcare interventions can improve HRQOL or functional status for this population. As a possible first step, a structural standard could be systematic collection of these measures in a specific setting. CONCLUSION Although functional status and HRQOL are important outcomes for older people with MCCs, few relevant ambulatory quality indicators exist, and there are concerns with usability, feasibility, and validity. Further research is needed on how best to incorporate these outcomes into quality indicators for people with MCCs. PMID:24320819

    2006-07-01

    This study explored the extent to which three types of racism-related stress (i.e., individual, institutional, and cultural) would predict the use of specific Africultural coping strategies (i.e., cognitive/emotional debriefing, spiritual-centered, collective, and ritual-centered coping) and religious problem-solving styles (i.e., self-directing, deferring, and collaborative) in a sample of 284 African American men and women. The authors found that higher institutional racism-related stress was associated with greater use of cognitive/emotional debriefing, spiritual-centered, and collective coping in African American women. Findings also indicated that higher cultural racism-related stress was predictive of lower use of self-directing religious problem-solving in African American women. Moreover, higher perceived cultural racism-related stress was related to greater use of collective coping strategies in African American men. Individual racism-related stress was not predictive of any forms of Africultural coping strategies or religious problem-solving. Implications of the findings are discussed.

    [Purpose] The aim of this study was to assess patients' health-related quality of life, compare it with a healthy age-matched population, and examine associations between functional ability and quality of life among juvenile rheumatoid arthritis (JRA) patients. [Subjects and Methods] The study participants were 26 JRA patients and 25 controls. The Childhood Health Assessment Questionnaire and the Pediatric Quality of Life Inventory 4.0 Generic Core Scales were used to evaluate functional ability and health-related quality of life, respectively. [Results] Functional ability scores averaged 0.37 in the JRA group and 0.08 in the control group. There were significant between-group differences in functional ability scores in the overall cohort and in the subgroup of participants aged 14-16 years. Health-related quality of life scores were significantly lower in the JRA group than in the control group (68.39 vs. 85.17). In the JRA group, functional ability was statistically positively correlated with health-related quality of life. [Conclusion] We conclude that the mental state of adolescents with JRA affects their particular functional abilities. Subjects in the 14-16 age group who had a longer disease duration and higher difficulty scores showed a lower health-related quality of life than children in the other age groups.

    Transnational marriages in Taiwan are largely mediated by marriage brokers. The present study was conducted to evaluate the satisfaction of immigrant women with their family function and health-related quality of life in a rural township in southern Taiwan. Data were collected from January 1, 2006 to November 31, 2006, and 157 immigrants agreed to participate in the study, with a 79.3% response rate. A structured questionnaire was used for data collection. The interviewers also collected information on the immigrants' and husbands' demographics, self-reported mental conditions, family function using a Family APGAR questionnaire (Adaptability, Partnership, Growth, Affection, and Resolve), and health-related quality of life. Marriage arranged through a marriage broker and having emotional distress were factors that were strongly associated with lower Family APGAR scores. Based on multiple regression models, higher Family APGAR scores were more positively related to vitality and mental health scales. Self-reported mental conditions, including feeling economic distress, emotional distress, loneliness, and having sleep problems, were negatively associated with most scales of the health-related quality of life. Female migrants' mental health was significantly related to their health-related quality of life. These findings suggest that migrant women must be educated regarding the importance of mental health by physicians and hygiene authorities in Taiwan.

    The bone has the functions of mineral reservoir and mechanical support as skeleton. Bone remodeling is the adult mode of bone metabolism, replacing old bone tissue to new one. Bone strength is determined by bone volume, structure and quality such as micro damage, degree of mineralization and collagen cross linkage, which are all controlled by bone remodeling. Bone strength decreases under high turn-over condition by decreasing bone volume and deterioration of bone structure, which also decreases under low turn-over condition by increased micro damage, increasing mineralization and AGE collagen cross linkage.

    Although studies on the association of job dissatisfaction with mental health have been conducted in the past, few studies have dealt with the complicated links connecting job stress, job dissatisfaction, and stress-related illness. This study seeks to determine how job dissatisfaction is linked to common mental health issues. This study surveyed 3,172 civil servants (2,233 men and 939 women) in 1998, taking poor mental functioning, fatigue, and sleep disturbance as stress-related mental health problems. We examine how psychosocial risk factors at work and job dissatisfaction are associated independently with poor mental functioning, fatigue, and sleep disturbance after adjustment for other known risk factors, and how job dissatisfaction contributes to change in the degree of association between psychosocial risk factors at work and mental health problems. In general, psychosocial risk factors were independently associated with mental health problems. When adjusted for job dissatisfaction, not only was job satisfaction independently associated with mental health problems but it was also found that the association of psychosocial risk factors with mental health problems declined. Our results suggest that, although longitudinal research is necessary, attitudes toward satisfaction at work can potentially decrease the negative effects of psychosocial risk factors at work on mental health.

    The 7-point stencil Dispersion-Relation-Preserving scheme of Tam and Webb is used to solve all the six categories of the CAA benchmark problems. The purpose is to show that the scheme is capable of solving linear, as well as nonlinear aeroacoustics problems accurately. Nonlinearities, inevitably, lead to the generation of spurious short wave length numerical waves. Often, these spurious waves would overwhelm the entire numerical solution. In this work, the spurious waves are removed by the addition of artificial selective damping terms to the discretized equations. Category 3 problems are for testing radiation and outflow boundary conditions. In solving these problems, the radiation and outflow boundary conditions of Tam and Webb are used. These conditions are derived from the asymptotic solutions of the linearized Euler equations. Category 4 problems involved solid walls. Here, the wall boundary conditions for high-order schemes of Tam and Dong are employed. These conditions require the use of one ghost value per boundary point per physical boundary condition. In the second problem of this category, the governing equations, when written in cylindrical coordinates, are singular along the axis of the radial coordinate. The proper boundary conditions at the axis are derived by applying the limiting process of r approaches 0 to the governing equations. The Category 5 problem deals with the numerical noise issue. In the present approach, the time-independent mean flow solution is computed first. Once the residual drops to the machine noise level, the incident sound wave is turned on gradually. The solution is marched in time until a time-periodic state is reached. No exact solution is known for the Category 6 problem. Because of this, the problem is formulated in two totally different ways, first as a scattering problem then as a direct simulation problem. There is good agreement between the two numerical solutions. This offers confidence in the computed results. Both

  17. The effects of group monitoring on fatigue-related einstellung during mathematical problem solving.

    PubMed

    Frings, Daniel

    2011-12-01

    Fatigue resulting from sleep deficit can lead to decreased performance in a variety of cognitive domains and can result in potentially serious accidents. The present study aimed to test whether fatigue leads to increased Einstellung (low levels of cognitive flexibility) in a series of mathematical problem-solving tasks. Many situations involving fatigue and problem solving also involve people working in teams. However, little research has considered the role of social processes in managing the effects of fatigue. Research into the group monitoring hypothesis suggests that membership in a team can offset the effects of impairing factors such as fatigue upon performance. Thus, the present study also aimed to test whether group membership exacerbates or ameliorates the negative effects of fatigue. During the course of a weekend military training exercise, participants (N = 171) attempted to solve a series of problems either alone or in a team, and while either reasonably alert (nonfatigued) or fatigued through sleep deficit. Fatigued problem solvers working alone showed increased Einstellung. In contrast, and in line with the group monitoring hypothesis, teams of fatigued problem solvers did not experience increased Einstellung. The present study also showed that teams with a group member who was relatively less fatigued experienced less Einstellung than other groups. These effects persisted even once participants were cued toward more direct strategies. These findings highlight the risk of Einstellung when fatigued and also the importance of team membership with reference to problem solving in an occupational context.

    Air pollution in Mexico City has increased along with the growth of the city, the movement of its population, and the growth of employment created by industry. The main cause of pollution in the city is energy consumption. Therefore, it is necessary to take into account the city`s economic development and its prospects when considering the technological relationships between well-being and energy consumption. Air pollution in the city from dust and other particles suspended in the air is an old problem. However, pollution as we know it today began about 50 years ago with the growth of industry, transportation, and population. The level of well-being attained in Mexico City implies a high energy use that necessarily affects the valley`s natural air quality. However, the pollution has grown so fast that the City must act urgently on three fronts: first, following a comprehensive strategy, transform the economic foundation of the city with nonpolluting activities to replace the old industries, second, halt pollution growth through the development of better technologies; and third, use better fuels, emission controls, and protection of wooded areas.

  19. Future directions of meteorology related to air-quality research.

    PubMed

    Seaman, Nelson L

    2003-06-01

    Meteorology is one of the major factors contributing to air-pollution episodes. More accurate representation of meteorological fields has been possible in recent years through the use of remote sensing systems, high-speed computers and fine-mesh meteorological models. Over the next 5-20 years, better meteorological inputs for air quality studies will depend on making better use of a wealth of new remotely sensed observations in more advanced data assimilation systems. However, for fine mesh models to be successful, parameterizations used to represent physical processes must be redesigned to be more precise and better adapted for the scales at which they will be applied. Candidates for significant overhaul include schemes to represent turbulence, deep convection, shallow clouds, and land-surface processes. Improvements in the meteorological observing systems, data assimilation and modeling, coupled with advancements in air-chemistry modeling, will soon lead to operational forecasting of air quality in the US. Predictive capabilities can be expected to grow rapidly over the next decade. This will open the way for a number of valuable new services and strategies, including better warnings of unhealthy atmospheric conditions, event-dependent emissions restrictions, and now casting support for homeland security in the event of toxic releases into the atmosphere.

    Biogeochemical functioning of ecosystems is central to nutrient cycling, carbon balance, and several ecosystem services, yet it is not always clear why levels of function might vary among systems. Wetlands are widely recognized for their ability to alter concentrations of solutes and particles as water moves through them, but we have only general expectations for what attributes of wetlands are linked to variability in these processes. We examined changes in several water quality variables (dissolved oxygen, dissolved organic carbon, nutrients, and suspended particles) to ascertain which constituents are influenced during tidal exchange with a range of 17 tidal freshwater wetlands along the Hudson River, New York, USA. Many of the constituents showed significant differences among wetlands or between flooding and ebbing tidal concentrations, indicating wetland-mediated effects. For dissolved oxygen, the presence of even small proportional cover by submerged aquatic vegetation increased the concentration of dissolved oxygen in water returned to the main channel following a daytime tidal exchange. Nitrate concentrations showed consistent declines during ebbing tides, but the magnitude of decline varied greatly among sites. The proportional cover by graminoid-dominated high intertidal vegetation accounted for over 40% of the variation in nitrate decline. Knowing which water-quality alterations are associated with which attributes helps suggest underlying mechanisms and identifies what functions might be susceptible to change as sea level rise or salinity intrusion drives shifts in wetland vegetation cover.

Background Long work hours have been linked with poor patient outcomes in adult patient populations but little is known about the relationship in pediatric settings. Methods A secondary analysis of cross-sectional nurse survey data was conducted. Our analysis focused on 3,710 registered nurses who worked in 342 acute care hospitals that treated children. Results The majority of pediatric nurses worked 12 hour shifts especially in intensive care settings. Nurses who worked extended shifts of >13 hours reported worse job outcomes and lower quality and safety for patients compared to nurses who worked 8 hour shifts. Conclusions Allocating resources to nursing to improve working hours may be a productive strategy for administrators to improve the health and well-being of pediatric patients and nurses PMID:23343725

    Objective We tested whether conduct problems moderate the relation between negative mood and drinking in adolescents as consistent with either a self-medication or a drinking consequences model. Method The sample included 75 rising ninth graders who completed a two-stage, multi-method, multi-reporter study. We used experience sampling to assess negative mood and drinking over 21 days and Hierarchical Linear Modeling to test our hypotheses. Results Counter to predictions, both self-medication and drinking consequence mechanisms were only evident in youth with fewer conduct problems. Conclusions Findings provide support for the importance of considering multiple mechanisms as underlying the relation between negative mood and drinking as pertaining to sub-populations of vulnerable youth. Implications for prevention and understanding negative mood-drinking relations in adolescents are discussed. PMID:18299772

    Research has addressed the consequences of being a victim of physical and relational aggression, but less so the consequences of being an aggressor during adolescence. Consequently, relatively little is known about the extent to which aggression in early adolescence increases the risk of later aggression and other psychosocial problems. This study involves a representative sample of 7th- and 9th-grade students from Washington State (N = 1,942). Students were surveyed upon recruitment, and then again 1 and 2 years later, to learn about ongoing behavior problems, substance use, depression, and self-harm behaviors. Surveys also included measures of several hypothesized promotive factors: attachment to family, school commitment, and academic achievement. Findings suggest that being physically and/or relationally aggressive in Grades 7–9 increases the risk of aggression and possibly other problem behaviors after accounting for age, gender, race, and a prior measures of each outcome. Independent promotive effects were observed in most analyses, although family attachment appeared a less robust predictor overall. Implications for prevention include reducing aggression and enhancing promotive influences to lessen the risk of ongoing problems. PMID:19297882

    Problems in population, manifested primarily as either "over" or "under" population, are ultimately related to the development of natural resources. Land is the most basic of natural resources. China's land mass is largely mountainous, with 56% of its more than 2000 counties, 1/3 of its population, 40% of its cultivated land and a majority of its forests, situated in mountainous regions. The quality and the distribution of the various kinds of land are complex and uneven. Although China is rich in forests, grazing, and arable land compared to the rest of the world, its 1 billion population makes the land a limited resource. The limitations of the land are also seen in soil erosion, soil that is increasingly turning into sand, and deforestation. Water resources are not considered scarce, yet compared to the rest of the world, it is limited. Its distribution is very uneven, with more water in the east and west, and less in the north and south. In the southwest mountainous border regions, for instance, water is abundant, but the population and arable land there is such that the demand for water is low. Moreover, droughts and heavy precipitation make the annual water supply unpredicatable. The demand for water becomes increasingly greater as agricultural production develops further, the population increases and as the cities continue to expand. living matter as a resource includes all the animal and plant life that is necessary for livelihood, but only forests and grasslands are discussed here. China's forests, if their use is not abused, can serve as a continuous supply for manufactured products. But its distribution is uneven and sparse. Population control will be ineffective if the forests are not replenished and developed. Grasslands are the primary source for animal products. The natural grasslands, found mainly in the north and west, are not as productive as that of other nations due to the nature of China's topography, the vagaries of climate, and deterioration

It is becoming increasingly common and frequent to establish relationships with patients with different cultural backgrounds. The aim of this study is analyzing Italian nurses' perception of the relational dynamics with foreign patients, to determine its evolution, and to identify the variables which can affect the quality of care. The study is both qualitative and quantitative with descriptive aim, using a questionnaire that assesses the theoretical-practical level of preparation, both perceptive and effective, of nurses when assisting foreign patients. To evaluate the emotional and experiential impact of the relationship with foreign patients, the difficulties encountered while establishing such relationship, and the resolution strategies - both effective and potential. The sample, composed of 101 Italian nurses employed at SanRaffaele Hospital in 6 specific Operational Units, resulted in a total of 91 returned questionnaires during the period May-June 2011. The data was analyzed through statistical instruments and compared to the results of a similar study done in 2004. The experience of intercultural nursing is seen by the sample as interesting and rewarding. The vast majority of nurses have positive responses. The more frequent issues are those connected with communication with foreign patients, and those connected with the increase workload due the presence of foreign patients. Nurses responded to difficulties more with human skills than with specific abilities, and tend to delegate the problem to the Cultural Mediation service. This new issue has a very high impact on nurses. The emerged difficulties have not decreased over time, this due to the lack of a proper policy within health care facilities in recent years, with the exception of a little improvement on the academic education. However the current academic education does not provide solutions useful in the everyday routing

    Purpose The main aim of our research was to evaluate general health, functioning, and performance parameters, as well as care problems of Geriatric Clinic inpatients in relation to deficits in fulfilling needs. The assessment of health-related quality of life was also performed. Patients and methods The research subjects were patients attending the Clinic of Geriatrics: 149 women and 78 men; 227 persons in total. The research was carried out using a diagnostic poll method, with the application of the Activities of Daily Living questionnaire of assessment of daily efficiency on the basis of the Katz index, the Instrumental Activities of Daily Living questionnaire, the Care Dependency Scale used to measure the level of care dependency and human needs, and the Nottingham Health Profile scale. Results The results showed that the majority of respondents achieved high and medium levels of functional capability. The main problems associated with the fulfillment of needs were difficulties with the adoption of appropriate body posture, movement restrictions, and problems related to participating in unassisted leisure activities outside the home. The general deficit in fulfilling the needs of the patients was low. The most significant problems were related to sleep disorders, restrictions in freedom of movement, loss of vital energy, and ailments resulting in the observable presence of pain. Conclusion Good daily functioning of elderly patients significantly depended on their intellectual and mental efficiency. Elderly patients require a comprehensive, holistic approach to a variety of problems that occur with aging. PMID:25565788

    Identifying children at risk for reading problems or dyslexia at kindergarten age could improve support for beginning readers. Brain event-related potentials (ERPs) were measured for temporally complex pseudowords and corresponding non-speech stimuli from 6.5-year-old children who participated in behavioral literacy tests again at 9 years in the second grade. Children who had reading problems at school age had larger N250 responses to speech and non-speech stimuli particularly at the left hemisphere. The brain responses also correlated with reading skills. The results suggest that atypical auditory and speech processing are a neural-level risk factor for future reading problems.

    2012-08-01

    In this paper, a population balance equation, originating from applications in chemical engineering, is considered and novel solution techniques for a related inverse problem are presented. This problem consists in the determination of the breakage rate and the daughter drop distribution of an evolving drop size distribution from time-dependent measurements under the assumption of self-similarity. We analyze two established solution methods for this ill-posed problem and improve the two procedures by adapting suitable data fitting and inversion algorithms to the specific situation. In addition, we introduce a novel technique that, compared to the former, does not require certain a priori information. The improved stability properties of the resulting algorithms are substantiated with numerical examples.

    Moisture problems in buildings have in a number of studies been shown to increase the risk for respiratory symptoms. The study Dampness in Buildings and Health (DBH) was initiated with the aim to identify health relevant exposures related to dampness in buildings. A questionnaire study about home environment with a focus on dampness problems and health was conducted in one county of Sweden (8,918 homes, response rate 79%). Building characteristics that were associated with one or more of the dampness indicators were for single-family houses, older houses, flat-roofed houses built in the 1960s and 1970s, houses with a concrete slab on the ground that were built before 1983. Moreover, tenancy and earlier renovation due to mould or moisture problems was strongly associated with dampness. A perception of dry air was associated with window-pane condensation, e.g. humid indoor air. PMID:19557598

    Efforts to define hypothalamic-pituitary-adrenal (HPA) axis profiles conferring risk for psychopathology have yielded inconclusive results, perhaps in part due to limited assessment of the stress response. In particular, research has typically focused on HPA responses to performance tasks, while neglecting the interpersonal stressors that become salient during adolescence. In this study we investigated links between psychosocial adjustment - youth internalizing and externalizing problems, as well as competence - and HPA responses to both performance and interpersonal stressors in a normative sample of children and adolescents. Participants (n = 59) completed a set of performance (public speaking, mental arithmetic, mirror tracing) and/or interpersonal (peer rejection) tasks and gave nine saliva samples, which were assayed for cortisol. Hierarchical linear models of cortisol response trajectories in relation to child behavior checklist (CBCL) scores revealed stressor- and sex-specific associations. Whereas internalizing problems related to earlier peaking, less dynamic cortisol responses to interpersonal stress (across males and females), externalizing problems related to lower, earlier peaking and less dynamic cortisol responses to performance stress for males only, and competence-related to later peaking cortisol responses to interpersonal stress for females only. Implications for understanding contextual stress profiles underlying different forms of psychopathology are discussed. PMID:27470923

    Objective: The increasing number of available drugs and drug users, as well as more complex drug regimens led to more side effects and drug interactions and complicates follow-up. The objective of this study was to assess drug-related problems (DRPs) and associated factors in hospitalized patients. Methods: A hospital-based cross-sectional study design was employed. The study was conducted in Jimma University Specialized Hospital, Jimma, located in the south west of Addis Ababa. All patients who were admitted to the medical ward from February 2011 to March 2011 were included in the study. Data on sociodemographic variables, past medical history, drug history, current diagnosis, current medications, vital signs, and relevant laboratory data were collected using semi-structured questionnaire and data collection forms which were filling through patient interview and card review. Data were analyzed using SPSS version 16 for windows. Descriptive statistics, cross-tabs, Chi-square, and logistic regression were utilized. Findings: Out of 257 study participants, 189 (73.5%) had DRPs and a total of 316 DRPs were identified. From the six classes of DRPs studied, 103 (32.6%) cases related to untreated indication or need additional drug therapy, and 49 (15.5%) cases related to high medication dosage. Unnecessary drug therapy in 49 (15.5%) cases, low medication dosage in 44 (13.9%) cases, and ineffective drug therapy in 42 (13.3%) cases were the other classes of problems identified. Noncompliance in 31 (9.8%) cases was the least prevalent DRP. Independent factors which predicted the occurrence of DRPs in the study population were sex, age, polypharmacy, and clinically significant potential drug-drug interactions. The prevalence of DRPs was substantially high (73.5%). Conclusion: Drug-related problems are common among medical ward patients. Indication-related problems, untreated indication and unnecessary drug therapy were the most common types of DRPs among patients of our

    Little is known about the health-related quality of life of former lead workers. Using the Short-Form 36 Questionnaire (SF-36), a cross-section design study evaluated the health-related quality of life of 186 former workers of a lead smelter that operated in Santo Amaro da Purificação, Brazil, from 1960 to 1993, when it closed down. The smelter had very poor occupational and environmental hygiene standards. The health-related quality of life of former lead workers was low, compared to population-based and other nosological groups from Brazil. Former lead workers who indicated metal poisoning, difficulty getting another job and who could not get another job after dismissal by the smelter presented poorer health-related quality of life. Former lead workers with poor health-related quality of life form part of the huge occupational liability left by the Santo Amaro lead smelter.

    Most biological studies related to waterquality conditions in the Western Lake Michigan Drainages have focused on populations and community structure of aquatic biota. Chemical concentrations in tissues of aquatic biota have been the next most common area of research. Our review suggests a paucity of data related to the health of all types of aquatic biota, especially amphibians, invertebrates, and reptiles; toxicity studies also were relatively uncommon. Overall, organisms primarily studied have been fish and invertebrates, although birds are most frequently examined in studies of organism health. The Fox/ Wolf Subbasin has been the focus of many more studies than the other subbasins, most likely because of the greater extent and severity of known water-quality problems in the Lower Fox River/Green Bay area over the past several decades and because it is the largest subbasin. Studies in the other subbasins are needed to adequately assess the water quality of these areas.

  20. The problems of relative deprivation: why some societies do better than others.

    2007-11-01

    In this paper, we present evidence which suggests that key processes of social status differentiation, affecting health and numerous other social outcomes, take place at the societal level. Understanding them seems likely to involve analyses and comparisons of whole societies. Using income inequality as an indicator and determinant of the scale of socioeconomic stratification in a society, we show that many problems associated with relative deprivation are more prevalent in more unequal societies. We summarise previously published evidence suggesting that this may be true of morbidity and mortality, obesity, teenage birth rates, mental illness, homicide, low trust, low social capital, hostility, and racism. To these we add new analyses which suggest that this is also true of poor educational performance among school children, the proportion of the population imprisoned, drug overdose mortality and low social mobility. That ill health and a wide range of other social problems associated with social status within societies are also more common in more unequal societies, may imply that income inequality is central to the creation of the apparently deep-seated social problems associated with poverty, relative deprivation or low social status. We suggest that the degree of material inequality in a society may not only be central to the social forces involved in national patterns of social stratification, but also that many of the problems related to low social status may be amenable to changes in income distribution. If the prevalence of these problems varies so much from society to society according to differences in income distribution, it suggests that the familiar social gradients in health and other outcomes are unlikely to result from social mobility sorting people merely by prior characteristics. Instead, the picture suggests that their frequency in a population is affected by the scale of social stratification that differs substantially from one society to

    Background Although drinking for tension reduction has long been posited as a risk factor for alcohol-related problems, studies investigating anxiety in relation to risk for alcohol problems have returned inconsistent results, leading researchers to search for potential moderators. Negative urgency (the tendency to become behaviorally dysregulated when experiencing negative affect) is a potential moderator of theoretical interest because it may increase risk for alcohol problems among those high in negative affect. The present study tested a cross-sectional mediated moderation hypothesis whereby an interactive effect of anxiety and negative urgency on alcohol problems is mediated through coping-related drinking motives. Method The study utilized baseline data from a hazardously drinking sample of young adults (N = 193) evaluated for participation in a randomized controlled trial of naltrexone and motivational interviewing for drinking reduction. Results The direct effect of anxiety on physiological dependence symptoms was moderated by negative urgency such that the positive association between anxiety and physiological dependence symptoms became stronger as negative urgency increased. Indirect effects of anxiety and negative urgency on alcohol problems (operating through coping motives) were also observed. Conclusions Although results of the current cross-sectional study require replication using longitudinal data, the findings suggest that the simultaneous presence of anxiety and negative urgency may be an important indicator of risk for AUDs via both direct interactive effects and indirect additive effects operating through coping motives. These findings have potentially important implications for prevention/intervention efforts for individuals who become disinhibited in the context of negative emotional states. PMID:26031346

    Shy-sensitive children are likely to develop adjustment problems in today's urban China as the country has evolved into an increasingly competitive, market-oriented society. The main purpose of this one-year longitudinal study was to examine the moderating effects of academic achievement on relations between shyness-sensitivity and later internalizing problems in Chinese children. A sample of 1171 school-age children (591 boys, 580 girls) in China, initially at the age of 9 years, participated in the study. Data on shyness, academic achievement, and internalizing problems were collected from multiple sources including peer evaluations, teacher ratings, self-reports, and school records. It was found that shyness positively and uniquely predicted later loneliness, depression, and teacher-rated internalizing problems, with the stability effect controlled, for low-achieving children, but not for high-achieving children. The results indicate that, consistent with the stress buffering model, academic achievement may be a buffering factor that serves to protect shy-sensitive children from developing psychological problems.

    This study examined the frequency and predictors of physical assault and having trouble with the police due to drinking over 16 years among women and men who, at baseline, were untreated for their alcohol use disorder. Predictors examined were the personal characteristics of impulsivity, self-efficacy, and problem-solving and emotional-discharge coping, as well as outpatient treatment and Alcoholics Anonymous (AA) participation. Women and men were similar on rates of perpetrating assault due to drinking, but men were more likely to have had trouble with the police due to drinking. Respondents who, at baseline, were more impulsive and relied more on emotional discharge coping, and less on problem-solving coping, assaulted others more frequently during the first year of follow-up. Similarly, less problem-solving coping at baseline was related to having had trouble with the police more often at one and 16 years due to drinking. The association between impulsivity and more frequent assault was stronger for women, whereas associations of self-efficacy and problem-solving coping with less frequent assault and police trouble were stronger for men. Participation in AA was also associated with a lower likelihood of having trouble with the police at one year, especially for men. Interventions aimed at decreasing impulsivity and emotional discharge coping, and bolstering self-efficacy and problem-solving coping, during substance abuse treatment, and encouragement to become involved in AA, may be helpful in reducing assaultive and other illegal behaviors.

    The aim of the present study was to describe how care providers discursively constructed and framed problems related to the occurrence of violence in their interactions with older persons in institutional care. The study followed a social constructionist approach where violence was considered a social phenomenon constructed in discursive processes. It was based on the assumption that in the way in which a problem is articulated is closely connected to solutions that are possible and relevant in a given context. The analysed corpus comprised narrative interviews with 46 care providers who had been involved in violence that occurred in social interactions with older persons. The analysis was inspired by discourse theory. The problems concerned legitimization, illness, bodily care, competence and profession and relieved responsibility. The constructions of the problems are manifestations of discourses. The prevailing discourses in the text are the medical and the physical. The construction of problems can be used to challenge dominant ways of thinking as well as the beliefs and common understandings about the subject.

    The literature reveals no qualitative study concerning the consequences of low-grade glioma in adults. The aim of the present study was to describe perceived illness-related problems in persons with low-grade glioma and the coping used in everyday living. The study was cross-sectional within a well-defined population. A semi-structured qualitative interview was conducted with each of 39 persons, and the data were subjected to inductive content analysis. There was a wide range of perceived problems, mainly concerning bodily functions, memory, cognition, emotion, communication and perception. Several coping strategies emerged, the most frequent being searching for a solution, which was often related to memory and communication problems. One characteristic of communication was the creation of new words. Other common strategies were refraining from and avoiding and laughing and joking. Caring about self involved prioritizing of personal needs. A striving to feel a sense of solidarity within seeking social affinity was coping with a novel content. The study provides vivid narratives about previously unreported phenomena, conveying a deeper understanding. The variety and endurance of problems revealed verifies the need of support from several professionals, including in the form of out-patient post-medical care. PMID:15669016

    Problems related to the design of the hardware for an integrated aircraft electronic system are considered. Taxonomies of concurrent systems are reviewed and a new taxonomy is proposed. An informal methodology intended to identify feasible regions of the taxonomic design space is described. Specific tools are recommended for use in the methodology. Based on the methodology, a preliminary strawman integrated fault tolerant aircraft electronic system is proposed. Next, problems related to the programming and control of inegrated aircraft electronic systems are discussed. Issues of system resource management, including the scheduling and allocation of real time periodic tasks in a multiprocessor environment, are treated in detail. The role of software design in integrated fault tolerant aircraft electronic systems is discussed. Conclusions and recommendations for further work are included.

    An advance study of materials, fuel injection, and hot flow problems related to the gas core nuclear rocket is reported. The first task was to test a previously constructed induction heated plasma GCNR simulator above 300 kW. A number of tests are reported operating in the range of 300 kW at 10,000 cps. A second simulator was designed but not constructed for cold-hot visualization studies using louvered walls. A third task was a paper investigation of practical uranium feed systems, including a detailed discussion of related problems. The last assignment resulted in two designs for plasma nozzle test devices that could be operated at 200 atm on hydrogen.

    Twenty-seven general medical practitioners (GPs) were administered WHO semi-structured schedule enquiring "The Management of Alcohol-Related Problems in General Practice". Majority of the GPs had some involvement in each one of the specified alcohol-related problems. The involvement in alcohol and health education had been modest. Involvement in the control and regulatory activities was minimal. None of them felt that they had any role in the development of health and alcohol policy. Treatment response lo three typical situations appeared to be quite appropriate. To regulate production, to market less potent drinks at cheaper rates, to organize public health education programme through mass media were the suggestions made by them. It is suggested that GPs can and should be encouraged in leadership roles in policy decisions regarding the delivery of services, control and regulation of alcohol and research.

    2003-08-01

    Recent research has found a positive association between insecure adult attachment styles and harmful drinking patterns. In the present study, we examined the relation between alcohol-related consequences and two dimensions underlying attachment, 'model of self' and 'model of others,' among a population of college student drinkers (N=366). It was predicted that a negative model of self would contribute significantly to the variance in drinking problems over and above that accounted for by level of alcohol consumption. In an attempt to clarify the nature of the relationship among these variables, it was further hypothesized that coping drinking motives would mediate the relationship between the self attachment dimension and alcohol consequences. Hierarchical multiple regression analyses revealed results consistent with the predictions. There was a significant relationship between negative model of self and problems which was fully mediated by coping drinking motives. The findings support the basic theoretical supposition that one primary function of interpersonal attachment is the regulation of emotions.

    The improvement of numerical weather prediction models in recent decades has led to a measurable decrease in forecast error, for instance as quantified by the 500-hPa geopotential height anomaly correlation. This improvement can be attributed in part to the refinements in the numerical architecture and the representation of physical processes in the model. It is more difficult to attribute the reduction in forecast error to improvements in the accuracy of the models' initial conditions, not least because of the complexity of the data assimilation process. As a contribution to this problem that will also be pedagogically useful, a reforecast experiment was conducted using a simple regional vorticity equation model for the 500-hPa flow over North America. This model is comparable in complexity to the Charney-Fjörtoft-von Neumann model used for the first numerical weather prediction experiment in 1949. Six-hourly predictions are made out to 36 hours for the period from 1948-2010, using the NCEP Reanalysis dataset for the initial conditions. Because initialization is trivial for this "filtered" model, one can clearly attribute the change in forecast skill to the changing quality of the initial state. The choice of the 500 hPa level is relevant since it will reflect the effect of the significant change in the density of upper-air observations from the mid- to late 20th Century. As an important byproduct of this exercise, a trend of improved forecast over time will imply an improved relative quality of the reanalysis data for the mid-troposphere. Therefore, the experiment serves two purposes of studying the forecast error and checking the quality of the reanalysis. An analysis of selected cases indicates that the predictions made for the 21st century have smaller errors compared to those made for the 1950s. A comprehensive analysis for the whole set of forecast is underway and the outcome will be discussed.

    The goals of surgery in treating intractable epilepsy are to eliminate seizures and improve quality of life. This report describes the development of the Epilepsy Surgery Inventory (ESI)-55, a 55-item measure of health-related quality of life for epilepsy patients. The ESI-55 includes the following scales (number of items in parentheses): health perceptions (9), energy/fatigue (4), overall quality of life (2), social function (2), emotional well-being (5), cognitive function (5), physical function (10), pain (2), and three separate scales of role limitations due to emotional, physical, or memory problems (5 items each). Also included is one change in health item. The ESI-55 was completed by 89% of 224 adults who had undergone a protocol evaluation for epilepsy surgery since 1974. Alpha internal consistency reliability coefficients ranged from 0.76 to 0.88 except for social function (alpha = 0.68). Multitrait scaling analyses supported item discrimination across scales. Factor analysis confirmed previously identified mental and physical health factors, and yielded a third factor defined by cognitive function and role limitations scales. Construct validity was supported by correlations of the ESI-55 with a mood profile instrument. Analysis of ESI-55 scale scores by seizure classification showed that the 44 patients who were seizure-free following surgery scored higher than did 55 patients who continued to have seizures (P less than 0.05 for all comparisons); 43 patients having seizures without loss of consciousness scored in between. Results of this study indicate that the ESI-55 is reliable, valid, and sensitive to differences in seizure status. PMID:1556879

  17. Satellite remote sensing of particulate matter air quality: the cloud-cover problem.

    PubMed

    Christopher, Sundar A; Gupta, Pawan

    2010-05-01

    Satellite assessments of particulate matter (PM) air quality that use solar reflectance methods are dependent on availability of clear sky; in other words, mass concentrations of PM less than 2.5 microm in aerodynamic diameter (PM2.5) cannot be estimated from satellite observations under cloudy conditions or bright surfaces such as snow/ice. Whereas most ground monitors measure PM2.5 concentrations on an hourly basis regardless of cloud conditions, space-borne sensors can only estimate daytime PM2.5 in cloud-free conditions, therefore introducing a bias. In this study, an estimate of this clear-sky bias is provided from monthly to yearly time scales over the continental United States. One year of the Moderate Resolution Imaging Spectroradiometer (MODIS) 550-nm aerosol optical depth (AOD) retrievals from Terra and Aqua satellites, collocated with 371 U.S. Environmental Protection Agency (EPA) ground monitors, have been analyzed. The results indicate that the mean differences between PM2.5 reported by ground monitors and PM2.5 calculated from ground monitors during the satellite overpass times during cloud-free conditions are less than +/- 2.5 microg m(-3), although this value varies by season and location. The mean differences are not significant as calculated by t tests (alpha = 0.05). On the basis of this analysis, it is concluded that for the continental United States, cloud cover is not a major problem for inferring monthly to yearly PM2.5 from space-borne sensors.

  1. Quality in health care: what are the problems and what are the solutions?

    PubMed

    Shipon, D M; Nash, D B

    2000-10-01

    The health care industry must define quality as achieving "desired health outcomes" that are "consistent with current professional knowledge." Once a single definition is established, health care professionals can begin to measure quality and improve the process of health care in this country. Clinical variation and an increasing number of medical mistakes have contributed to rising health care costs and poor quality. Once the industry establishes what is wrong, it can begin to devise some solutions to improve the quality of health care. A six-step strategy to improve quality is suggested: increasing accountability at all levels of the industry, continuous quality improvement, standardization of medicine using guidelines, patient empowerment, improved access to health information through a centralized database, and the need for incentives for patients and medical professionals. Although many physicians are skeptical of such changes, the health care industry clearly must work together to address the issue of quality appropriately.

    OBJECTIVE--To determine the incidence of drug related problems that fail to be noted on casualty cards in patients subsequently admitted, and to compare medication histories as recorded by accident and emergency (A&E) senior house officers (SHOs) and a pharmacist. METHODS--An initial retrospective survey of 1459 acute inpatient admissions through A&E over a three month period was followed by a prospective study of 33 elderly patients. RESULTS--In the retrospective survey, 52 medication related problems were confirmed after examination of the medical records, of which only 16 were identified in A&E. In the prospective study, 125 currently prescribed items were identified by the pharmacist compared to 77 by A&E SHOs; 66% of the missed information was clinically relevant. Of 17 previous adverse drug reactions identified by the pharmacist only six were also recorded by the A&E officer. Only four over the counter medicines were identified by the A&E SHOs compared to 30 by the pharmacist. CONCLUSIONS--More accurate recording of drug history on casualty cards should be undertaken, particularly in respect of over the counter medication and the identification of drug related problems.

    2015-08-01

    A well-known recurrence relation for the 6j-symbol of the quantum group suq(2) is realized as a tridiagonal, symmetric eigenvalue problem. This formulation can be used to implement an efficient numerical evaluation algorithm, taking advantage of existing specialized numerical packages. For convenience, all formulas relevant for such an implementation are collected in Appendix A. This realization is a byproduct of an alternative proof of the recurrence relation, which generalizes a classical (q = 1) result of Schulten and Gordon and uses the diagrammatic spin network formalism of Temperley-Lieb recoupling theory to simplify intermediate calculations.

    The present study examined the association of denture quality and health-related quality of life (HRQoL) in patients with removable dentures. In a study of 171 consecutive patients with removable partial dentures or complete dentures (mean age: 68·0 ± 9·3 years) at a university-based prosthodontic clinic, dentists rated two aspects of denture quality (stability and aesthetics) using a 100-mm visual analog scale (VAS). HRQoL was evaluated using the mental and physical component summary (MCS and PCS) scores of the Medical Outcomes Study Short-Form 36-Item Health Survey (SF-36). Oral health-related quality of life (OHRQoL) was evaluated using the Oral Health Impact Profile-Japanese version (OHIP-J). The associations among denture quality, OHRQoL, and HRQoL were examined by linear regression models. Bivariable linear regression analyses revealed that denture stability was significantly associated with the SF-36 MCS [regression coefficient = 0·52 for a 10-unit increase in denture stability on a 0-100 VAS, 95% confidence interval (CI): 0·03-1·00, P = 0·04], but not with the PCS (0·11, 95% CI: -0·49 to 0·70). Denture aesthetics was not related to the PCS or the MCS (0·22, 95% CI: -0·44 to 0·88 or 0·07, 95%CI: -0·47 to 0·62). When OHIP-J was added to the regression model, this variable was substantially and significantly associated with the MCS and PCS summary scores; in addition, the regression coefficient for denture quality decreased in magnitude and was statistically nonsignificant in all analyses. The quality of removable dentures had a minimal effect on HRQoL in patients with removable dentures, and this association was mediated by OHRQoL.

    Motives for gambling have been shown to have an important role in gambling behavior, consistent with the literature on motives for substance use. While studies have demonstrated that traits related to sensitivity to reward (SR) and sensitivity to punishment (SP) are predictive of substance use motives, little research has examined the role of these traits in gambling motives. This study investigated motivational pathways from SR and SP to gambling frequency and gambling problems via specific gambling motives, while also taking into account history of substance use disorder (SUD). A community sample of gamblers (N = 248) completed self-report questionnaires assessing SR, SP, gambling frequency, gambling-related problems, and motives for gambling (social, negative affect, and enhancement/winning motives). Lifetime SUD was also assessed with a structured clinical interview. The results of a path analysis showed that SR was uniquely associated with all 3 types of gambling motives, whereas SP and SUD were associated with negative affect and enhancement/winning motives but not social motives. Also, both negative affect and enhancement/winning motives were associated with gambling problems, but only enhancement/winning motives were significantly related to gambling frequency. Analyses of indirect associations revealed significant indirect associations from SR, SP, and SUD to gambling frequency mediated through enhancement/winning motives and to gambling problems mediated through both negative affect and enhancement/winning motives. The findings highlight the importance of SR and SP as independent predictors of gambling motives and suggest that specific motivational pathways underlie their associations with gambling outcomes.

    2008-07-30

    A body of literature now exists, which demonstrates that idiopathic Parkinson's disease (PD) has a major negative impact on quality of life (QoL), and that depression and cognitive impairment are among the main predictors of poor QoL in this disorder. Relatively little work has been done to assess the differential contribution of the specific symptoms of PD to QoL, which was the aim of this study. One hundred thirty patients with PD completed a booklet of questionnaires, which included the PDQ39 as a disease-specific measure of QoL, a symptom checklist, a mobility checklist, as well as patient ratings of disease stage and disability. The results indicated that the contribution of physical, medication-related, and cognitive/psychiatric symptoms to QoL can be significant. Sudden unpredictable on/off states, difficulty in dressing, difficulty in walking, falls, depression, and confusion were PD symptoms, which significantly influenced QoL scores. Among the mobility problems associated with PD, start hesitation, shuffling gait, freezing, festination, propulsion, and difficulty in turning had a significant effect on QoL scores. In addition to depression and anxiety, the major predictors of QoL were shuffling, difficulty turning, falls, difficulty in dressing, fatigue, confusion, autonomic disturbance particularly urinary incontinence, unpredictable on/off fluctuations, and sensory symptoms such as pain. The implications of these results for the medical management of PD are discussed. PMID:18543333

    Cancer related fatigue (CRF) is a common and debilitating symptom that can influence quality of life (QoL) in cancer patients. The increase in survival times stresses for a better understanding of how CRF affects patients' QoL. This was a cross-sectional descriptive study with 148 randomly recruited prostate cancer patients aiming to explore CRF and its impact on QoL. Assessments included the Cancer Fatigue Scale, EORTC QLQ-C30, and EORTC QLQ-PR25. Additionally, 15 in-depth structured interviews were performed. Quantitative data were analyzed with simple and multiple regression analysis and independent samples t-test. Qualitative data were analyzed with the use of thematic content analysis. The 66.9% of the patients experienced CRF with higher levels being recorded for the affective subscale. Statistically significant differences were found between the patients reporting CRF and lower levels of QoL (mean = 49.1) and those that did not report fatigue and had higher levels of QoL (mean = 72.1). The interviews emphasized CRF's profound impact on the patients' lives that was reflected on the following themes: “dependency on others,” “loss of power over decision making,” and “daily living disruption.” Cancer related fatigue is a significant problem for patients with advanced prostate cancer and one that affects their QoL in various ways.

    This chapter reviews selected epidemiologic studies on drinking and associated problems among US ethnic minorities. Ethnic minorities and the White majority group exhibit important differences in alcohol use and related problems, including alcohol use disorders. Studies show a higher rate of binge drinking, drinking above guidelines, alcohol abuse, and dependence for major ethnic and racial groups, notably, Blacks, Hispanics, and American Indians/Alaskan Natives. Other problems with a higher prevalence in certain minority groups are, for example, cancer (Blacks), cirrhosis (Hispanics), fetal alcohol syndrome (Blacks and American Indians/Alaskan Natives), drinking and driving (Hispanics, American Indians/Alaskan Natives). There are also considerable differences in rates of drinking and problems within certain ethnic groups such as Hispanics, Asian Americans, and American Indians/Alaskan Natives. For instance, among Hispanics, Puerto Ricans and Mexican Americans drink more and have higher rates of disorders such as alcohol abuse and dependence than Cuban Americans. Disparities also affect the trajectory of heavy drinking and the course of alcohol dependence among minorities. Theoretic accounts of these disparities generally attribute them to the historic experience of discrimination and to minority socioeconomic disadvantages at individual and environmental levels.

    Until recently, most high-end scientific applications have been immune to performance problems caused by Non-Uniform Memory Access (NUMA). However, current trends in micro-processor design are pushing NUMA to smaller and smaller scales. This paper examines the current state of NUMA and makes several contributions. First, we summarize the performance problems that NUMA can present for multithreaded applications and describe methods of addressing them. Second, we demonstrate that NUMA can indeed be a significant problem for scientific applications, showing that it can mean the difference between an application scaling perfectly and failing to scale at all. Third, we describe, in increasing order of usefulness, three methods of using hardware performance counters to aid in finding NUMA-related problems. Finally, we introduce Memphis, a data-centric toolset that uses Instruction Based Sampling to help pinpoint problematic memory accesses, and demonstrate how we used it to improve the performance of several production-level codes - HYCOM, XGC1 and CAM - by 13%, 23% and 24% respectively.

    Dysphagia in Duchenne muscular dystrophy (DMD) worsens with age, with increasingly effortful mastication. The aims of this study were to describe mastication problems in consecutive stages in a group of patients with DMD and to determine related pathophysiological aspects of masticatory muscle structure, tongue thickness, bite force and dental characteristics. Data from 72 patients with DMD (4.3 to 28.0 years), divided into four clinical stages, were collected in a cross sectional study. Problems with mastication and the need for food adaptations, in combination with increased echogenicity of the masseter muscle, were already found in the early stages of the disease. A high percentage of open bites and cross bites were found, especially in the later stages. Tongue hypertrophy also increased over time. Increased dysfunction, reflected by increasingly abnormal echogenicity, of the masseter muscle and reduced occlusal contacts (anterior and posterior open bites) were mainly responsible for the hampered chewing. In all, this study shows the increasing involvement of various elements of the masticatory system in progressive Duchenne muscular dystrophy. To prevent choking and also nutritional deficiency, early detection of chewing problems by asking about feeding and mastication problems, as well as asking about food adaptations made, is essential and can lead to timely intervention.

    1995-12-31

    Suspended Particulate Matter (SPM) is a major pollutant, followed by carbon monoxide and lead, as the ambient levels of these pollutants all exceed international standards such as those laid down by the World Health Organization (WHO). In order to meet these standards, it is necessary to reduce the emissions of these pollutants by 84.9%, 47.3%, and 13.0% respectively. Ambient air quality in Bangkok will continue to deteriorate to an unacceptable level by the year 2000, if no action is taken over and above implementation of already approved projects (including mass transit projects). Carbon monoxide and hydrocarbon emissions could be reduced by 28 and 22% respectively, with the implementation of Reasonable Technology Measures used to control vehicle emissions alone. These measures include inspection and maintenance programs. Their success is dependent on effective quality control and on the application of stringent standards. However, these measures would have little impact in reducing the emissions of SPM. It can therefore be concluded that Reasonable Technology Measures will be insufficient to address Bangkok`s air pollution problems, without complementary measures to reduce traffic congestion. Implementation of the traffic measures outlined under the Demand-Management Policy Scenario alone will reduce CO and HC emissions by up to 45%. These measures serve to reduce traffic congestion and increase the average travel speed. However, in order to improve air quality to internationally acceptable levels, traffic measures must be implemented in conjunction with the Reasonable Technology Scenario. This will provide an additional reduction of CO and HC emissions by 45%.

    The health-related quality of life of school-aged children with high-functioning autism is poorly understood. The objectives of this study were to compare the health-related quality of life of children with high-functioning autism to that of typically developing peers and to compare child-self and parent-proxy reports of health-related quality of life of children. A cross-sectional study of children with high-functioning autism (n = 30) and peers (n = 31) was conducted using the Pediatric Quality of Life Inventory 4.0 Generic Core Scales. Children with high-functioning autism had significantly poorer health-related quality of life than peers whether reported by themselves (p < .001) or their parents (p < .001), although disagreement (intra-class coefficient = -.075) between children and parental scores suggested variance in points of view. This study specifically investigated health-related quality of life in children with high-functioning autism as compared to a sample of peers, from the child's perspective. It strengthens earlier findings that children with high-functioning autism experience poorer health-related quality of life than those without this disorder and points to the importance of clinicians working with families to identify areas in a child's life that promote or hinder their sense of well-being.

    The current study examined bidirectional, longitudinal links between prosocial and problem behavior. Participants (N = 500) were recruited from a Northwestern city in the United States and assessed for 3 consecutive years from 2009 to 2011 (M(age) of youth at Time 1 = 13.32, SD = 1.05; 52% girls; 67% European American, 33% single-parent families). Results suggested that effects of earlier prosocial behavior toward family and strangers were predictive of fewer problem behaviors 2 years later, while results for prosocial behavior toward friends were more mixed. Results also suggested depression predicted lower prosocial behavior toward family members and anxiety predicted higher prosocial behavior toward friends. Findings show a complex pattern of relations that demonstrate the need to consider targets of helping.

    OBJECTIVES: To gain insight into similarities and differences in patient evaluations of quality of primary care across 12 European countries and to correlate patient evaluations with WHO health system performance measures (for example, responsiveness) of these countries. METHODS: Patient evaluations were derived from a series of Quote (QUality of care Through patients' Eyes) instruments designed to measure the quality of primary care. Various research groups provided a total sample of 5133 patients from 12 countries: Belarus, Denmark, Finland, Greece, Ireland, Israel, Italy, the Netherlands, Norway, Portugal, United Kingdom, and Ukraine. Intraclass correlations of 10 Quote items were calculated to measure differences between countries. The world health report 2000 - Health systems: improving performance performance measures in the same countries were correlated with mean Quote scores. FINDINGS: Intra-class correlation coefficients ranged from low to very high, which indicated little variation between countries in some respects (for example, primary care providers have a good understanding of patients' problems in all countries) and large variation in other respects (for example, with respect to prescription of medication and communication between primary care providers). Most correlations between mean Quote scores per country and WHO performance measures were positive. The highest correlation (0.86) was between the primary care provider's understanding of patients' problems and responsiveness according to WHO. CONCLUSIONS: Patient evaluations of the quality of primary care showed large differences across countries and related positively to WHO's performance measures of health care systems. PMID:15042232

    Nursing home residents have a high prevalence of remediable visual impairment and blindness. Future research on the effectiveness of providing eye care to nursing home residents will need to include a vision-targeted health-related quality of life (HRQOL) instrument appropriate for this population. The purpose of this study was to identify the core content areas for such an instrument. In-depth interviews on vision-related issues were conducted with 40 residents. Interviews were audio-taped, transcribed, and coded using a standardized protocol. Binocular distance and near visual acuity were assessed using the resident's 'walking around' correction to examine whether one vision-specific HRQOL measure could address the needs of residents with 'good' and 'poor' vision. Overall 1070 vision-related comments were identified. Residents mentioned 315 problem comments that were grouped into 13 categories, including ocular symptoms (18% of comments), reading (15%), general vision (13%), psychological distress (12%), and activities of daily living (ADLs) (7%). Compared to published data on vision-specific content areas most relevant to community based persons, nursing home residents focused more on ocular symptoms and basic ADLs, with no mention of issues related to driving, home care, and finances. The majority of categories mentioned did not differ on the proportion of comments made- by those with 'good' and 'poor' visual acuity, suggesting that one vision-specific HRQOL instrument would be appropriate for residents with varying levels of visual acuity. Future work will focus on developing a vision-specific HRQOL instrument for nursing home residents.

    Special needs plans (SNPs) were created under the Medicare Modernization Act of 2003 to focus on Medicare beneficiaries who required more coordination of care than most beneficiaries served through the Medicare Advantage program. This research indicates that beneficiaries in 3 types of SNPs show evidence of worse health-related quality of life. Special needs plans demonstrated worse plan performance on the HEDIS osteoporosis testing in older women measure compared with non-SNP Medicare Advantage beneficiaries, but better plan performance on the HEDIS fall risk management measure. Future research should consider broader measures of plan performance, quality of care, and cost.

    Improvement for carcass traits related to beef quality is the key concern in beef production. Recent reports found that epigenetics mediates the interaction of individuals with environment and nutrition. The present study was designed to analyze the genetic effect of single nucleotide polymorphisms (SNPs) in seven epigenetic-related genes (DNMT1, DNMT3a, DNMT3b, DNMT3L, Ago1, Ago2, and HDAC5) and two meat quality candidate genes (CAPN1 and PRKAG3) on fourteen carcass traits related to beef quality in a Snow Dragon beef population, and also to identify SNPs in a total of fourteen cattle populations. Sixteen SNPs were identified and genotyped in 383 individuals sampled from the 14 cattle breeds, which included 147 samples from the Snow Dragon beef population. Data analysis showed significant association of 8 SNPs within 4 genes related to carcass and/or meat quality traits in the beef populations. SNP1 (13154420A>G) in exon 17 of DNMT1 was significantly associated with rib-eye width and lean meat color score (p<0.05). A novel SNP (SNP4, 76198537A>G) of DNMT3a was significantly associated with six beef quality traits. Those individuals with the wild-type genotype AA of DNMT3a showed an increase in carcass weight, chilled carcass weight, flank thicknesses, chuck short rib thickness, chuck short rib score and in chuck flap weight in contrast to the GG genotype. Five out of six SNPs in DNMT3b gene were significantly associated with three beef quality traits. SNP15 (45219258C>T) in CAPN1 was significantly associated with chuck short rib thickness and lean meat color score (p<0.05). The significant effect of SNP15 on lean meat color score individually and in combination with each of other 14 SNPs qualify this SNP to be used as potential marker for improving the trait. In addition, the frequencies of most wild-type alleles were higher than those of the mutant alleles in the native and foreign cattle breeds. Seven SNPs were identified in the epigenetic-related genes. The SNP

  19. The Pennsylvania Experience with Hydraulic Fracturing for Shale Gas Development: Relatively Infrequent Water Quality Incidents with Lots of Public Attention

    Brantley, S. L.; Li, Z.; Yoxtheimer, D.; Vidic, R.

    2015-12-01

    New techniques of hydraulic fracturing - "fracking" - have changed the United States over the last 10 years into a leading producer of natural gas extraction from shale. The first such gas well in Pennsylvania was drilled and completed using high-volume hydraulic fracturing in 2004. By late 2014, more than 8500 of these gas wells had been drilled in the Marcellus Shale gas field in Pennsylvania alone. Almost 1000 public complaints about groundwater quality were logged by the PA Department of Environmental Protection (PA DEP) between 2008 and 2012. Only a fraction of these were attributed to unconventional gas development. The most common problem was gas migration into drinking water, but contamination incidents also included spills, seepage, or leaks of fracking fluids, brine salts, or very occasionally, radioactive species. Many problems of gas migration were from a few counties in the northeastern part of the state. However, sometimes one gas well contaminated multiple water wells. For example, one gas well was reported by the state regulator to have contaminated 18 water wells with methane near Dimock PA. It can be argued that such problems at a relatively small fraction of gas wells initiated pockets of pushback against fracking worldwide. This resistance to fracking has grown even though fracking has been in use in the U.S.A. since the 1940s. We have worked as part of an NSF-funded project (the Shale Network) to share water quality data and publish it online using the CUAHSI Hydrologic Information System. Sharing data has led to collaborative investigation of specific contamination incidents to understand how problems can occur, and to efforts to quantify the frequency of impacts. The Shale Network efforts have also highlighted the need for more transparency with water quality data in the arena related to the energy-water nexus. As more data are released, new techniques of data analysis will allow better understanding of how to tune best practices to be

  20. The usefulness of circulating adipokine levels for the assessment of obesity-related health problems

    2008-01-01

    Because the prevalence of obesity has increased dramatically in recent years, one of the key targets of public health is obesity and its associated pathological conditions. Obesity occurs as a result of white adipose tissue enlargement, caused by adipocyte hyperplasia and/or hypertrophy. Recently, endocrine aspects of adipose tissue have become an active research area and these adipose tissue-derived factors are referred to as adipokines. These adipokines interact with a range of processes in many different organ systems and influence a various systemic phenomena. Therefore, dysregulated production of adipokines has been found to participate in the development of metabolic and vascular diseases related to obesity. The obese state is also known to be associated with increased local and systemic inflammation. Adipokines influence not only systemic insulin resistance and have pathophysiological roles in the metabolic syndrome and cardiovascular disease, but also contribute toward an increase in local and systemic inflammation. Thus, circulating levels of adipokines can be used as high-throughput biomarkers to assess the obesity-related health problems, including low grade inflammation. This review focuses on the usefulness of measuring circulating adipokine levels for the assessment of obesity-related health problems. PMID:18773088

    The management of diabetes is complicated, as treatment affects the everyday life of both children and their families. To enable optimal care for children with type 1 diabetes, it is important to highlight health-related quality of life (HrQoL) as well as medical outcomes to detect psychological problems that otherwise could be missed. The aim was to study HrQoL in children and adolescents with type 1 diabetes dependent on gender, age and co-morbidity and to study the consistency between children's self-reporting and parents' proxy reporting. The cross-sectional data were collected using the questionnaire DISABKIDS Chronic Generic Measure and the DISABKIDS diabetes module. Parents in the proxy report perceived their children's HrQoL to be lower than children themselves. Boys reported their HrQoL to be better than girls. Results show that living with an additional disease has an impact on the HrQoL, which is an important factor to consider in the quality registry. Assessing HrQoL on a routine basis may facilitate detection and discussion of HrQoL-related questions in the national quality registry.

    This study aimed to investigate the effects of Qigong intervention on quality of life (QOL), health-related functioning, and cancer-related symptoms in survivors of nasopharyngeal cancer (NPC). Twenty-five survivors of NPC were included in the experimental group (mean age ± SD: 55.4 ± 7.5 years) and 27 in the control group (mean age ± SD: 58.7 ± 9.5 years). The experimental group underwent a weekly 1.5-hour Qigong training program and an identical home program (three times/week) for six months. The control group received no training. Global health status/QOL, functioning, and cancer-related symptoms were assessed by the European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-H&N35 questionnaires before training began, after three months of Qigong training, at the end of the six-month Qigong intervention (i.e., posttest), and six months posttest. Intention-to-treat analysis revealed no statistically (P > 0.05) or clinically significant improvement in global health status/QOL, functioning, or symptoms in either group. The experimental group had 45.8% fewer sense-related (smell and taste) problems (P < 0.05) but 98.6% more speech-related problems (P < 0.05) than the control group after the Qigong intervention. Qigong training resulted in no apparent improvement in health-related QOL, functionality, or cancer-related symptoms in cancer-free survivors of NPC, except for a possible reduction in smell- and taste-related problems.

    Economic crises are complex events that affect behavioral patterns (including alcohol consumption) via opposing mechanisms. With this realist systematic review, we aimed to investigate evidence from studies of previous or ongoing crises on which mechanisms (How?) play a role among which individuals (Whom?). Such evidence would help understand and predict the potential impact of economic crises on alcohol consumption. Medical, psychological, social, and economic databases were used to search for peer-reviewed qualitative or quantitative empirical evidence (published January 1, 1990-May 1, 2014) linking economic crises or stressors with alcohol consumption and alcohol-related health problems. We included 35 papers, based on defined selection criteria. From these papers, we extracted evidence on mechanism(s), determinant, outcome, country-level context, and individual context. We found 16 studies that reported evidence completely covering two behavioral mechanisms by which economic crises can influence alcohol consumption and alcohol-related health problems. The first mechanism suggests that psychological distress triggered by unemployment and income reductions can increase drinking problems. The second mechanism suggests that due to tighter budget constraints, less money is spent on alcoholic beverages. Across many countries, the psychological distress mechanism was observed mainly in men. The tighter budget constraints mechanism seems to play a role in all population subgroups across all countries. For the other three mechanisms (i.e., deterioration in the social situation, fear of losing one's job, and increased non-working time), empirical evidence was scarce or absent, or had small to moderate coverage. This was also the case for important influential contextual factors described in our initial theoretical framework. This realist systematic review suggests that among men (but not among women), the net impact of economic crises will be an increase in harmful

    Background Weight-related problems are prevalent in adolescent girls. Purpose To evaluate New Moves, a school-based program aimed at preventing weight-related problems in adolescent girls. Design School-based group-randomized controlled design. Setting/participants 356 girls (mean age=15.8± 1.2 years) from six intervention and six control high schools. Over 75% of the girls were racial/ethnic minorities and 46% were overweight or obese. Data were collected in 2007–2009 and analyzed in 2009–2010. Intervention An all-girls physical education class, supplemented with nutrition and self-empowerment components, individual sessions using motivational interviewing, lunch meetings, and parent outreach. Main outcome measures Percent body fat, BMI, physical activity, sedentary activity, dietary intake, eating patterns, unhealthy weight control behaviors, and body/self-image. Results New Moves did not lead to significant changes in the girls’ percent body fat or BMI but improvements were seen for sedentary activity, eating patterns, unhealthy weight control behaviors, and body/self-image. For example, in comparison to control girls, at 9-month follow-up, intervention girls decreased their sedentary behaviors by approximately one 30-minute block a day (p=.050); girls increased their portion control behaviors (p=.014); the percentage of girls using unhealthy weight control behaviors decreased by 13.7% (p=.021), and improvements were seen in body image (p=.045) and self-worth (p=.031). Additionally, intervention girls reported more support by friends, teachers, and families for healthy eating and physical activity. Conclusions New Moves provides a model for addressing the broad spectrum of weight-related problems among adolescent girls. Further work is needed to enhance the effectiveness of interventions to improve weight status of youth. PMID:20965379

    Background Health-related quality of life (HRQoL) is considered an important outcome measure in chronic diseases, in particular cardiovascular disease (CVD), which is known to be associated with impaired HRQoL. However, few studies have examined HRQoL in individuals at high risk of CVD. Methods Using the Fifth Korea National Health and Nutrition Examination Survey 2010-2012, we analyzed data from 10,307 adults aged ≥30 years. The study subjects were stratified into 3 groups on the basis of their Framingham risk score-a 10-year estimate of CVD risk: <10.0% (low risk), 10.0%-19.9% (moderate risk), and ≥20.0% (high risk). The EuroQol-5D (EQ-5D) was used to evaluate HRQoL. Results A significantly higher proportion of high-risk subjects than low-risk participants had impaired HRQoL (defined as the lowest quartile of the EQ-5D index); this held true even after adjustment for confounding factors in multivariable logistic regression analysis (men: odds ratio [OR], 1.62; 95% confidence interval [CI], 1.24-2.11; women: OR, 1.46; 95% CI, 1.02-2.08). In terms of the 5 EQ-5D dimensions, a 10-year CVD risk ≥20.0% was significantly associated with self-reported problems of mobility in men (OR, 3.15; 95% CI, 2.02-4.90), and of mobility (OR, 1.56; 95% CI, 1.09-2.24), self-care (OR, 2.14; 95% CI, 1.09-4.22), and usual activity problems (OR, 1.80; 95% CI, 1.17-2.78) in women. Conclusion A high CVD risk is associated with impaired HRQoL. After adjustment for demographic and clinical factors, a 10-year CVD risk ≥20.0% is an independent predictor of impaired HRQoL in the general population; in particular, of mobility problems in men, and of mobility, self-care, and usual activity problems in women.

    The relationship between mathematical creativity (MC) and mathematical problem-solving performance (MP) has often been studied but the causal relation between these two constructs has yet to be clearly reported. The main purpose of this study was to define the causal relationship between MC and MP. Data from a representative sample of 480 eighth-grade students were analysed using a cross-lagged panel correlation (CLPC) design. CLPC attempts to rule out plausible alternative explanation of a causal effect. The result suggests that significant predominant causal relationship was found between MC and MP. It indicates that MP was found to be a cause of MC than the converse.

    Background: The extensive use of computers as medium of teaching and learning in universities necessitates introspection into the extent of computer related health disorders among student population. Aim: This study was undertaken to assess the pattern of computer usage and related visual problems, among University students in Ajman, United Arab Emirates. Materials and Methods: A total of 500 Students studying in Gulf Medical University, Ajman and Ajman University of Science and Technology were recruited into this study. Demographic characteristics, pattern of usage of computers and associated visual symptoms were recorded in a validated self-administered questionnaire. Chi-square test was used to determine the significance of the observed differences between the variables. The level of statistical significance was at P < 0.05. The crude odds ratio (OR) was determined using simple binary logistic regression and adjusted OR was calculated using the multiple logistic regression. Results: The mean age of participants was 20.4 (3.2) years. The analysis of racial data reveals that 50% (236/471) students were from Middle East, 32% (151/471) from other parts of Asia, 11% (52/471) from Africa, 4% (19/471) from America and 3% (14/471) from Europe. The most common visual problems reported among computer users were headache - 53.3% (251/471), burning sensation in the eyes - 54.8% (258/471) and tired eyes - 48% (226/471). Female students were found to be at a higher risk. Nearly 72% of students reported frequent interruption of computer work. Headache caused interruption of work in 43.85% (110/168) of the students while tired eyes caused interruption of work in 43.5% (98/168) of the students. When the screen was viewed at distance more than 50 cm, the prevalence of headaches decreased by 38% (50-100 cm – OR: 0.62, 95% of the confidence interval [CI]: 0.42-0.92). Prevalence of tired eyes increased by 89% when screen filters were not used (OR: 1.894, 95% CI: 1

    Background The goal of cardiac rehabilitation programs is not only to prolong life but also to improve physical functioning, symptoms, well-being, and health-related quality of life (HRQL). The aim of this study was to document the long-term effect of a 1-month inpatient cardiac rehabilitation intervention on HRQL in Austria. Methods Patients (N = 487, 64.7% male, age 60.9 ± 12.5 SD years) after myocardial infarction, with or without percutaneous interventions, coronary artery bypass grafting or valve surgery underwent inpatient cardiac rehabilitation and were included in this long-term observational study (two years follow-up). HRQL was measured with both the MacNew Heart Disease Quality of Life Instrument [MacNew] and EuroQoL-5D [EQ-5D]. Results All MacNew scale scores improved significantly (p < 0.001) and exceeded the minimal important difference (0.5 MacNew points) by the end of rehabilitation. Although all MacNew scale scores deteriorated significantly over the two year follow-up period (p < .001), all MacNew scale scores still remained significantly higher than the pre-rehabilitation values. The mean improvement after two years in the MacNew social scale exceeded the minimal important difference while MacNew scale scores greater than the minimal important difference were reported by 40-49% of the patients. Two years after rehabilitation the mean improvement in the EQ-5D Visual Analogue Scale score was not significant with no significant change in the proportion of patients reporting problems at this time. Conclusion These findings provide a first indication that two years following inpatient cardiac rehabilitation in Austria, the long-term improvements in HRQL are statistically significant and clinically relevant for almost 50% of the patients. Future controlled randomized trials comparing different cardiac rehabilitation programs are needed. PMID:19995445

    Background and purpose To assess the impact of intensity modulated radiotherapy (IMRT) versus conventional radiation on late xerostomia and Quality of Life aspects in head and neck cancer patients. Patients and nethods Questionnaires on xerostomia in rest and during meals were sent to all patients treated between January 1999 and December 2003 with a T1-4, N0-2 M0 head and neck cancer, with parotid gland sparing IMRT or conventional bilateral neck irradiation to a dose of at least 60 Gy, who were progression free and had no disseminated disease (n = 192). Overall response was 85% (n = 163); 97% in the IMRT group (n = 75) and 77% in the control group (n = 88) the median follow-up was 2.6 years. The prevalence of complaints was compared between the two groups, correcting for all relevant factors at multivariate ordinal regression analysis. Results Patients treated with IMRT reported significantly less difficulty transporting and swallowing their food and needed less water for a dry mouth during day, night and meals. They also experienced fewer problems with speech and eating in public. Laryngeal cancer patients in general had fewer complaints than oropharynx cancer patients but both groups benefited from IMRT. Within the IMRT group the xerostomia scores were better for those patients with a mean parotid dose to the "spared" parotid below 26 Gy. Conclusion Parotid gland sparing IMRT for head and neck cancer patients improves xerostomia related quality of life compared to conventional radiation both in rest and during meals. Laryngeal cancer patients had fewer complaints but benefited equally compared to oropharyngeal cancer patients from IMRT. PMID:19068126

    This article reports an investigation of some of the skills needed for the critical reading of physics texts. To assess these skills a reading comprehension test was developed that combines features of errordetection and true-false-unreported tests. This test was administered to college students of physics, and the results were analyzed statistically to determine the separability of the skills and their hierarchical ranking. It was found that the skill required to comprehend texts in continuous format is of a higher level than and separable from the skill required to comprehend texts in the form of a separated list of statements. The skill required to discriminate unreported statements from the others (true and false) was found to be of a higher level than and separable from the skills required to make the other discriminations. The relation between the students' reading comprehension skills and their problem-solving ability was also investigated. Students' scores on reading comprehension of texts that require a very low problem-solving ability were found to be uncorrelated to their grades on solving problems that require a very low decoding ability. This implies that the two abilities are independent.Received: 31 August 1993; Revised: 27 July 1994;

    A brief analysis of different properties and principles of invariance to solve a number of classical problems of the radiation transport theory is presented. The main ideas, constructions, and assertions used in the general invariance relations reduction method are described in outline. The most important distinctive features of this general method of solving a wide enough range of problems of the radiation transport theory and mathematical physics are listed. To illustrate the potential of this method, a number of problems of the scalar radiative transfer theory have been solved rigorously in the article. The main stages of rigorous derivations of asymptotical formulas for the smallest in modulo elements of the discrete spectrum and the eigenfunctions, corresponding to them, of the characteristic equation for the case of an arbitrary phase function and almost conservative scattering are described. Formulas of the same type for the azimuthal averaged reflection function, the plane and spherical albedos have been obtained rigorously. New analytical representations for the reflection function, the plane and spherical albedos have been obtained, and effective algorithms for calculating these values have been offered for the case of a practically arbitrary phase function satisfying the Hölder condition. New analytical representation of the «surface» Green function of the scalar radiative transfer equation for a semi-infinite plane-parallel conservatively scattering medium has been found. The deep regime asymptotics of the "volume" Green function has been obtained for the case of a turbid medium of cylindrical form.

    Modern cities have been trying to meet their needs for space by using not only surface structures but also by considering subsurface space use. It is also anticipated that without planning of underground spaces for supporting surface city life in the years and generations to come, there will be serious and unavoidable problems with growing populations. The current Turkish cadastral system, including land right registrations, has been trying to meet users' needs in all aspects since 1924. Today Turkey's national cadastre services are carried out by the General Directorate of Land Titles and Cadastre (TKGM). The Cadastre Law, Number 3402, was approved in 1985 to eliminate problems by gathering all existing cadastral regulations under one law and also to produce 3D cadastral bases to include underground spaces and determine their legal status in Turkey. Although the mandate for 3D cadastre works is described and explained by the laws, until now the bases have been created in 2D and the reality is that legal gaps and deficiencies presently exist in them. In this study, the usage of underground spaces for the current cadastral system in Turkey was briefly evaluated, the concept of 3D cadastral data is examined and the need for using subsurface and 3D cadastre in addition to the traditional 2D register system, related problems and registration are mentioned with specific examples, but without focusing on a specific model.

    Sex differences in Einstellung Effects were confounded by attitudinal factors. Hypothesizing that this was the case for spatial visualization and restructurization, we compared male and female college students' solutions of three elementary geometric problems. Used by Max Wertheimer to study productive thinking, they call for a Gestalt, spatial approach. In group administration to 86 calculus students, males did somewhat better than females, but the reverse held in classes where most women majored in mathematics. Individual administration to 200 Ss, balanced for sex and major, showed that female mathematics majors had more solutions than other females: e.g., 51 percent more compared to 26 percent sex differences. Four hints were available for restructuring each problem. The percentage needing all four hints was highest for male nonmathematics major and next highest for female mathematics majors (e.g., 75 and 23 percent, respectively). Embarrassment at needing hints in such "easy problems" and ego-involvement were factors. Thus, sex differences were less pronounced than differences related to mathematical abilities and interests and to task-and ego-concerns. PMID:469505

    The NATO Advanced Research Workshop on Nuclear Submarine Decommissioning and Related Problems was held in Moscow June 19--22, 1995. It was preceded by a visit to the Zvezdotchka Shipyard at Severodvinsk, a repair and maintenance yard for Russian nuclear submarines, for a subgroup of the workshop attendees. Most of the material in this paper is drawn directly form the workshop proceedings. Slightly less than 500 nuclear ships and submarines (the vast majority are submarines) have been constructed by the countries with nuclear navies. This includes approximately 250 by Russia, 195 by the United States, 23 by the United Kingdom, 11 by France and 6 by China. By the year 2000 it is expected that approximately one-half of these nuclear vessels will be removed from service and in various states of decommissioning. A newspaper account in June 1997 indicated that 156 Russian nuclear submarines had been removed from service. In August 1996 it was reported that 55 reactor compartment sections from US nuclear submarines were already in long-term storage at Hanford. Overall the dismantlement of nuclear submarines and the processing, storage and disposal of nuclear fuel, activated components and section of the hulls, and the liquid and solid radioactive and hazardous wastes is an enormous problem. This problem has been exacerbated by the accelerated decommissioning schedule associated with treaty obligations.

    Viewing the role of technology as either the cause of or solution to environmental problems may be unrealistic, and such extreme attitudes may inhibit the resolution of environmental problems. Courses that present a particular orientation toward the role of technology may encourage these extreme attitudes. Identifying attitudes of students enrolled in such courses and designing instruction to foster specific attitudes can lead to a more rational and objective attitude toward technology as related to environmental problems. The Scientific-Environmental-Technological (SET) literacy model was suggested as an appropriate framework for presenting the role of technology to students. A 34 item Likert scale was developed to measure attitudes as defined by two constructs: PRO-technology and ANTI-technology. Students enrolled in three courses (E200, Environment and People, K201, The Computer in Business, E100, Freshman Engineering Lectures), were asked to respond to the survey at the beginning and end of the fall, 1980 semester. The findings indicate that the survey was useful in identifying and characterizing attitudes of certain populations. The differences between the E200 and E100 students indicate that instruction that recognizes and examines the full range of perspectives on the impact of technology should be provided for these students.

    Background The development of new therapeutics has led to progress in the early management of congenital diaphragmatic hernia (CDH) in pediatric intensive care units (PICU). Little is known about the impact on the quality of life (QoL) of children and their family. The aim of this study was to assess the impact of CDH treated according to the most recent concepts and methods outlined above on child survivors’ QoL and their parents’ QoL. Patients and methods This study incorporated a cross-sectional design performed in two PICU (Marseille, France). Families of CDH survivors born between 1999 and 2008 were eligible. The following data were recorded: socio-demographics, antenatal history and delivery, initial hospitalization history. Self-reported data were collected by mail, including current clinical problems of the children (13-symptom list), children’s QoL (Kidscreen-27 questionnaire), and parents’ QoL (Short-Form 36 questionnaire). Children’s QoL score was compared with controls and QoL of survivors of childhood leukemia. Parent’s QoL was compared with controls. Non-parametric statistics were employed. Results Forty-two families agreed to participate and questionnaires were completed by 32 of them. Twenty-one children had a current clinical problems related to CDH. All the QoL scores of CHD survivors were significantly lower compared with controls. The physical well-being dimension was significantly higher for CHD survivors compared with survivors of childhood leukemia. Gastro-esophageal reflux at discharge, antenatal diagnosis, length of stay in the PICU, and neuropsychological and respiratory issues significantly impacted QoL scores of children. The parents of CHD survivors had significantly poorer score in emotional role dimension compared with controls. Conclusion The impact of CDH on QoL seems to be important and must be understood by clinicians who treat these children and their parents. PMID:23786966

    Background Cough and sputum production are frequent in chronic obstructive pulmonary disease (COPD). The objective of this study was to examine the relationship between cough and sputum production and health-related quality of life in COPD. Methods A cross-sectional study was conducted in the French Initiatives COPD cohort and assessed cough and sputum production within the past 7 days using the cough and sputum assessment questionnaire (CASA-Q), health-related quality of life, spirometry, smoking status, dyspnea, exacerbations, anxiety and depression, and comorbidities. Results One hundred and seventy-eight stable COPD patients were included (age, 62 [56–69] years, 128 male, forced expiratory volume in 1 second [FEV1]: 57 [37–72] % predicted) (median [Q1–Q3]). In univariate analyses, health-related quality of life (Saint George’s respiratory questionnaire total score) was associated with each CASA-Q domain and with chronic bronchitis, exacerbations, dyspnea, FEV1, depression, and anxiety. All four domains introduced separately were independently associated with health-related quality of life. When introduced together in multivariate analyses, only the cough impact domain remained independently associated with health-related quality of life (R2=0.60). With chronic bronchitis (standard definition) instead of the CASA-Q, the R2 was lower (R2=0.54). Conclusion This study provides evidence that current cough in the previous 7 days is an important determinant of health-related quality of life impairment in stable COPD patients.

    The theory of task-based assessment of image quality is reviewed in the context of imaging with ionizing radiation, and objective figures of merit (FOMs) for image quality are summarized. The variation of the FOMs with the task, the observer and especially with the mean number of photons recorded in the image is discussed. Then various standard methods for specifying radiation dose are reviewed and related to the mean number of photons in the image and hence to image quality. Current knowledge of the relation between local radiation dose and the risk of various adverse effects is summarized, and some graphical depictions of the tradeoffs between image quality and risk are introduced. Then various dose-reduction strategies are discussed in terms of their effect on task-based measures of image quality. PMID:25564960
