Its main claim is that the value of autonomy holds strong potential for grounding sufficiency. It argues, firstly, that autonomy carries...... both personal value for its recipient as well as impersonal value, and that both of these values are suitable for grounding sufficiency. It thus follows that we should reject both (i) and (ii). Secondly, although autonomy is presumably the strongest candidate for grounding sufficiency, the article...... provides some counterargument to Segall’s rejection of the other candidates—the impersonal value of virtue; the personal value for the allocator; and the personal value for others. If the arguments are sound, they show that we need not worry about sufficientarianism being groundless....

Stability of matrices with sufficiently strong negative-dominant-diagonal submatrices

Nieuwenhuis, H.J.; Schoonbeek, L.

A well-known sufficient condition for stability of a system of linear first-order differential equations is that the matrix of the homogeneous dynamics has a negative dominant diagonal. However, this condition cannot be applied to systems of second-order differential equations. In this paper we

The changes in serum 25-hydroxyvitamin D (25(OH)D) in adolescents from summer to winter and optimal serum vitamin D levels in the summer to ensure adequate vitamin D levels at the end of winter are currently unknown. This study was conducted to address this knowledge gap. The study was conducted as a cohort study. Sixty-eight participants aged 7-18 years and who had sufficient vitamin D levels at the end of the summer in 2011 were selected using stratified random sampling. Subsequently, the participants' vitamin D levels were measured at the end of the winter in 2012. A receiver operating characteristic (ROC) curve was used to determine optimal cutoff points for vitamin D at the end of the summer to predict sufficient vitamin D levels at the end of the winter. The results indicated that 89.7% of all the participants had a decrease in vitamin D levels from summer to winter: 14.7% of them were vitamin D-deficient, 36.8% had insufficient vitamin D concentrations and only 48.5% where able to maintain sufficient vitamin D. The optimal cutoff point to provide assurance of sufficient serum vitamin D at the end of the winter was 40 ng/mL at the end of the summer. Sex, age and vitamin D levels at the end of the summer were significant predictors of non-sufficient vitamin D at the end of the winter. In this age group, a dramatic reduction in vitamin D was observed over the follow-up period. Sufficient vitamin D at the end of the summer did not guarantee vitamin D sufficiency at the end of the winter. We found 40 ng/mL as an optimal cutoff point.

Role of sufficient statistics in stochastic thermodynamics and its implication to sensory adaptation

Science.gov (United States)

Matsumoto, Takumi; Sagawa, Takahiro

2018-04-01

A sufficient statistic is a significant concept in statistics, which means a probability variable that has sufficient information required for an inference task. We investigate the roles of sufficient statistics and related quantities in stochastic thermodynamics. Specifically, we prove that for general continuous-time bipartite networks, the existence of a sufficient statistic implies that an informational quantity called the sensory capacity takes the maximum. Since the maximal sensory capacity imposes a constraint that the energetic efficiency cannot exceed one-half, our result implies that the existence of a sufficient statistic is inevitably accompanied by energetic dissipation. We also show that, in a particular parameter region of linear Langevin systems there exists the optimal noise intensity at which the sensory capacity, the information-thermodynamic efficiency, and the total entropy production are optimized at the same time. We apply our general result to a model of sensory adaptation of E. coli and find that the sensory capacity is nearly maximal with experimentally realistic parameters.

From "Buzzword" to Best Practice: Applying Intersectionality to Children Exposed to Intimate Partner Violence.

Science.gov (United States)

Etherington, Nicole; Baker, Linda

2016-03-07

Empirical studies on the impact of intimate partner violence (IPV) on children have burgeoned over the last three decades. Notably absent from existing approaches to studying children exposed to IPV, however, is attention to how various positionalities intersect to impact the experiences of children and their families. In fact, while the importance of an intersectional framework for understanding IPV has been discussed for over two decades, little or no attention has been given to issues of children's exposure to IPV. In this article, we examine the current state of the literature on children exposed to IPV through an exploratory meta-analysis, finding limited application of intersectionality and a focus on discrete categories of difference. We then demonstrate why and how an intersectional framework should be applied to children exposed to IPV, with specific strategies for research and policy. We suggest a child-centered approach that recognizes diversity among children exposed to IPV, extending the challenge to traditional "one-size-fits-all" models to include an intersectionality-informed stance. © The Author(s) 2016.

Full Text Available This study was performed in order to examine the relationship between organizational support perceptions and self-sufficiency levels of logistics sector employees and to determine whether organizational support perceptions and self-sufficiency levels of employees differ according to some specification. The questionnaire form consisting of perceived organizational support scale in accordance with the purpose, general self-sufficiency scale and personal information form, was applied to 124 employees of 3 separate logistics firms operating in Istanbul. The data obtained from the questionnaire were analyzed using SPSS17.0 statistical software package on computer. In the assessment of data, descriptive characteristics of employees were determined by frequency and percentage statistics and the self-sufficiency and perceived organizational support levels by the mean and standard deviation statistics. The t test, Tukey test and one-way Anova tests were utilized in determining employees' self-sufficiency and perceived organizational support levels differentiation according to descriptive characteristics, and correlation analysis was utilized in determining the relationship between self-sufficiency and perceived organizational support levels of employees. In conclusion, it was determined that there was statistical relationship between organizational support and self-sufficiency levels perceived by logistics sector employees. Accordingly, when employees' perceived organizational support levels increase then self-sufficiency levels also increase, and when perceived organizational support levels decrease then self-sufficiency levels also decrease.

To evaluate the parents' perspective with regard to evolution of their child with cochlear implant (CI). This was a cross-sectional prospective study conducted at the Centro de Pesquisas Audiológicas of Hospital de Reabilitação de Anomalias Craniofaciais of Universidade de São Paulo. The selection of the sample was performed from the spontaneous demand, among the months from July to December 2011. The final sample comprised 50 parents or guardians of children using CI, with minimum 1 year and maximum of 3 years of device use. The translated and adapted to Brazilian Portuguese version of the questionnaire "Perspectives of parents of children with cochlear implants" was applied. This instrument consists of 74 questions and allows quantification of the parents' perspective on subscales that illustrate the situation of the child and family. Each question has five options scored from one to five responses. The Spearman test for comparison of results between the subscales was applied. The social relationships, self-sufficiency, and communication subscales showed the highest mean score, whereas the worst score was for child support subscale, reflecting the independence and autonomy of the patients. The correlation between the child subscales was realized, and the results showed themselves significant and positive for communication subscale of communication with all others subscales. The family subscales also had a positive correlation with the communication, education, and self-sufficiency. These results demonstrate that parents have good expectations regarding communication, independence, and social participation of children after CI surgery, and this questionnaire is a useful tool for use in clinical practice.

Mitchell, Paul Mark; Roberts, Tracy E; Barton, Pelham M; Coast, Joanna

2015-08-01

Amartya Sen's capability approach has been discussed widely in the health economics discipline. Although measures have been developed to assess capability in economic evaluation, there has been much less attention paid to the decision rules that might be applied alongside. Here, new methods, drawing on the multidimensional poverty and health economics literature, are developed for conducting economic evaluation within the capability approach and focusing on an objective of achieving "sufficient capability". This objective more closely reflects the concern with equity that pervades the capability approach and the method has the advantage of retaining the longitudinal aspect of estimating outcome that is associated with quality-adjusted life years (QALYs), whilst also drawing on notions of shortfall associated with assessments of poverty. Economic evaluation from this perspective is illustrated in an osteoarthritis patient group undergoing joint replacement, with capability wellbeing assessed using ICECAP-O. Recommendations for taking the sufficient capability approach forward are provided. Copyright © 2015 Elsevier Ltd. All rights reserved.

Nowadays, the media have reported an increasing number of cases where children are accidentally being trapped in vehicles while they parents and guardians are away attending to other matters. In this paper we discuss the feasibility of applying Mechatronics to improve the safety of children in vehicles with the ultimate goal of developing a means for parents,guardians and authorities to be informed if ever there is a child trapped in a vehicle and in need of urgent assistance. We have also presented some preliminary experiments we have carried out for a safety alert system which is currently being developed in our lab.

In our cost- and radiation-conscious environment, the feasibility of performing only a frontal radiograph for the diagnosis of pneumonia in children needs to be reassessed. To determine the diagnostic efficacy of the frontal radiograph alone in comparison to the frontal and lateral combined radiographs for the radiographic diagnosis of pneumonia in children. Three radiologists retrospectively and independently reviewed the frontal radiographs alone and separately reviewed the frontal and lateral radiographs of 1,268 children referred from the emergency room for chest radiographs. A majority interpretation of at least two radiologists for the frontal views alone was compared with majority interpretation of the frontal and lateral combined views for the radiographic diagnosis of pneumonia. ''Pneumonia'' was defined as a focus of streaky or confluent lung opacity. For the radiographic diagnosis of pneumonia, the sensitivity and specificity of the frontal view alone were 85% and 98%, respectively. For the confluent lobar type of pneumonia, the sensitivity and specificity increased to 100%. When the frontal view alone yields a diagnosis of confluent lobar pneumonia, this is highly reliable. However, nonlobar types of infiltrates will be underdiagnosed in 15% of patients using the frontal view alone. The clinical impact of these radiographically underdiagnosed pneumonias needs to be assessed prior to implementing the practice of using only frontal radiographs for diagnosing pneumonia. (orig.)

Gupta, R.K.; Mittal, R.D.; Agarwal, K.N.; Agarwal, D.K.

1994-01-01

Muscle sufficiency was significantly lower in 1336 children with chronic malnutrition of moderate to severe degree. 18 children with a chronic moderate degree of malnutrition and 8 well-nourished age-matched controls were selected for biochemical and 31-phosphorus magnetic resonance spectroscopy (31-P MRS) studies. The results shows that: a) serum total protein, albumin, iron, calcium and inorganic phosphate were similar in both groups; b) serum enzyme levels were significantly increased in the malnuourished group; c) 31-P MRS showed significantly higher means for total ATP, β-ATP, α-ATP and inorganic phosphate for the malnourished compared to the control group. In chronic malnutrition, proteins are maintained by degradation in muscle resulting in release of amino acids and enzymes. 31-P MRS studies showing increases in total ATP, β-ATP and inorganic phosphate and a decrease in phosphocreatine suggest that ATP is maintained at the cost of phosphocreatine. 22 refs., 4 tabs. 1 fig

[The concept of nutritional self-sufficiency and the demographic equilibrium of Rwanda].

Science.gov (United States)

Habimana Nyirasafari, G

1987-12-01

Achieving food self-sufficiency is the basic strategy of Rwanda's 4th 5-year plan covering 1987-91. The population growth rate has increased from 3% in 1970 to 3.7% in 1983, with the population doubling between 1964 and 1985. Food production grew by about 4%/year between 1966-83, creating a slight increase in per capita food availability, but the 2171 calories available per capita is dangerously close to the theoretical minimum requirement of 2100 per day. The theoretical protein requirement is almost covered, but there is a serious shortage of oils. The increase in production since 1966 has been due almost exclusively to the extension of cultivated land. But the land supply is limited, and future production increases will need to be based on increased yields per unit cultivated. The National Office of Population has developed a simulation model that analyzes the parallel evolution of population and production so as to identify demographic and development policies that will assure food self-sufficiency and an improvement in living conditions. The population subsystem subjects the population divided by age and sex to the effects of fertility, migration, and mortality. Births are the result of 36 different fertility rates applied to the population of women aged 14-49 years. The agricultural subsystem is tied to the population subsystem by comparison of the volume of population to that of production, by estimation of the proportion of the population living exclusively by subsistence agriculture, by calculation of the potential emigration resulting from overpopulation of the countryside, and by estimation of the links between nutritional level, mortality, and duration of breastfeeding. 5 annexes contain subsystems showing effects of demographic growth on education, employment, and health. The model has various limitations including those of the reliability of its data, but it is sufficiently precise for its main function of clarifying the choices facing policymakers. 6

Full Text Available Two unified frameworks of some sufficient descent conjugate gradient methods are considered. Combined with the hyperplane projection method of Solodov and Svaiter, they are extended to solve convex constrained nonlinear monotone equations. Their global convergence is proven under some mild conditions. Numerical results illustrate that these methods are efficient and can be applied to solve large-scale nonsmooth equations.

Stable dynamics in forced systems with sufficiently high/low forcing frequency.

Bartuccelli, M; Gentile, G; Wright, J A

2016-08-01

We consider parametrically forced Hamiltonian systems with one-and-a-half degrees of freedom and study the stability of the dynamics when the frequency of the forcing is relatively high or low. We show that, provided the frequency is sufficiently high, Kolmogorov-Arnold-Moser (KAM) theorem may be applied even when the forcing amplitude is far away from the perturbation regime. A similar result is obtained for sufficiently low frequency, but in that case we need the amplitude of the forcing to be not too large; however, we are still able to consider amplitudes which are outside of the perturbation regime. In addition, we find numerically that the dynamics may be stable even when the forcing amplitude is very large, well beyond the range of validity of the analytical results, provided the frequency of the forcing is taken correspondingly low.

To observe the therapeutic effect of hydrotherapy with Chinese drugs (HT-C) in early intervention on children hypoxic ischemic encephalopathy (HIE). HIE children were assigned to the treatment group and the control group, 50 in each, at random depending on the willingness of patients' parents. Both groups received the conventional functional training, according to the "0 -3-year-old early intervention outline", but for the treatment group, HT-C was applied additionally. Indexes for quality of sleep, gross motor function, severity of spasm and intellectual development were observed and compared before and after treatment to assess the therapeutic effects. Therapeutic effect in the treatment group was better than that in the control group in all the indexes observed, showing statistical significance (all P <0.05). Early intervention of HT-C could improve clinical symptom, promote the functional recovery and intellectual development in children HIE, and also could reduce or prevent the sequelae occurrence of the nervous system in them.

Comparison of 72-hour fecal fat quantification and the 13C-mixed triglyceride breath test in assessing pancreatic exocrine sufficiency in children with chronic pancreatitis.

Science.gov (United States)

Wejnarska, Karolina; Kołodziejczyk, Elwira; Ryżko, Józef; Oracz, Grzegorz

Chronic pancreatitis (CP) in children is still a rare, although increasingly recognized entity. Over the duration of the disease several complications can be observed, two of which are major ones: endo- and exocrine insufficiency. In the medical care of children with CP it is crucial to diagnose the decreased endo- and exocrine function of the pancreas, in order to preserve patients from malnutrition and the failure to thrive. The aim of the study was to compare the usefulness of two indirect methods of assessing the pancreas exocrine function in children with CP. Ninety one patients with CP were enrolled in the study (41 boys, 50 girls, aged 2-17.8 years). Only Patients who had had both the 72-hour fecal fat quantification and the 13C-mixed triglyceride breath test (13C -MTBT) performed were selected. We compared the results of both tests for sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) in detecting exocrine pancreatic insufficiency. Out of 91 patients, 12 were diagnosed with exocrine pancreatic insufficiency (EPI). The sensitivity of the fecal fat quantification was 50%, the specificity for the test was 100%. PPV and NPV were 100% and 93%, respectively. 13C-MTBT had the sensitivity of 42% and the specificity of 99%. PPV and NPV for the breath test were of 83% and 92%, respectively. No statistically significant discrepancy between the values obtained was found. Although the 72-hour fecal fat quantification remains the gold standard in detecting EPI, both of the methods that had been investigated were shown to be comparable regarding sensitivity, specificity, PPV and NPV in assessing pancreas exocrine sufficiency in children with CP. Due to the easier execution of the breath test, both for the patient and for medical personnel, its importance may increase.

Furthermore, this decision perspective should be applied not only in determining the sufficiency of the programme, but also when optimising the remaining parts of the ongoing programme. In particular, it needs to be understood that the Site Investigation is only a step towards the ultimate decision of disposing waste and eventually sealing a repository. The cost and value of information obtained in the Site Investigation Phase, needs to be weighted against the costs and value of obtaining information during later stages. All issues need not be resolved during the Site Investigation Phase. Some could be much better handled later, e.g. during the construction and detailed investigation phase.

Sleep and memory in the making. Are current concepts sufficient in children?

Science.gov (United States)

Peigneux, P

2014-01-01

Memory consolidation is an active process wired in brain plasticity. How plasticity mechanisms develop and are modulated after learning is at the core of current models of sleep-dependent memory consolidation. Nowadays, two main classes of sleep-related memory consolidation theories are proposed, namely system consolidation and synaptic homeostasis. However, novel models of consolidation emerge, that might better account for the highly dynamic and interactive processes of encoding and memory consolidation. Processing steps can take place at various temporal phases and be modulated by interactions with prior experiences and ongoing events. In this perspective, sleep might support (or not) memory consolidation processes under specific neurophysiological and environmental circumstances leading to enduring representations in long-term memory stores. We outline here a discussion about how current and emergent models account for the complexity and apparent inconsistency of empirical data. Additionally, models aimed at understanding neurophysiological and/or cognitive processes should not only provide a satisfactory explanation for the phenomena at stake, but also account for their ontogeny and the conditions that disrupt their organisation. Looking at the available literature, this developmental condition appears to remain unfulfilled when trying to understand the relationships between sleep, learning and memory consolidation processes, both in healthy children and in children with pathological conditions.

Sufficiency does energy consumption become a moral issue?

Energy Technology Data Exchange (ETDEWEB)

Muller, Adrian (Socio-economic Inst. and Univ. Research Priority Programme in Ethics, Univ. of Zuerich, Zuerich (Switzerland))

2009-07-01

Reducing the externalities from energy use is crucial for sustainability. There are basically four ways to reduce externalities from energy use: increasing technical efficiency ('energy input per unit energy service'), increasing economic efficiency ('internalising external costs'), using 'clean' energy sources with few externalities, or sufficiency ('identifying 'optimal' energy service levels'). A combination of those strategies is most promising for sustainable energy systems. However, the debate on sustainable energy is dominated by efficiency and clean energy strategies, while sufficiency plays a minor role. Efficiency and clean energy face several problems, though. Thus, the current debate should be complemented with a critical discussion of sufficiency. In this paper, I develop a concept of sufficiency, which is adequate for liberal societies. I focus on ethical foundations for sufficiency, as the discussion of such is missing or cursory only in the existing literature. I first show that many examples of sufficiency can be understood as (economic) efficiency, but that the two concepts do not coincide. I then show that sufficiency based on moralization of actions can be understood as implementation of the boundary conditions for social justice that come with notions of liberal societies, in particular the duty not to harm other people. By this, to increase sufficiency becomes a duty beyond individual taste. I further illustrate this in the context of the adverse effects of climate change as externalities from energy use.

2013-11-01

Full Text Available Purpose. The basic criterion of the magnetically suspended train's consumer estimation is a quality of its mechanical motion. This motion is realized in unpredictable conditions and, for purposefulness preservation, should adapt to them. Such adaptation is possible only within the limits of system’s dynamic sufficiency. Sufficiency is understood as presence at system of resources, which allow one to realize its demanded motions without violating actual restrictions. Therefore presence of such resources is a necessary condition of preservation of required purposefulness of train's dynamics, and verification of the mentioned sufficiency is the major component of this dynamic research. Methodology. Methods of the set theory are used in work. Desirable and actual approachability spaces of the train are found. The train is considered dynamically sufficient in zones of the specified spaces overlapping. Findings. Within the limits of the accepted treatment of train's dynamic sufficiency, verification of its presence, as well as a stock (or deficiency of preservations can be executed by the search and the subsequent estimation of such overlapping zones. Operatively (directly during motion it can be realized on the train's ODC with use, for example, of computer mathematics system Mathematica. It possesses extensive opportunities of highly efficient and, at the same time, demanding an expense concerning small resources information manipulation. The efficiency of using of created technique is illustrated on an example of vehicle's acceleration research. Calculation is executed with use of the constructed computer model of interaction of an independent traction electromagnetic subsystem of an artifact with its mechanical subsystem. Originality. The technique of verification of the high-speed magnetically suspended train's dynamic sufficiency is developed. The technique is highly efficient, it provides sufficient presentation and demands an expense of the

Self-sufficiency, free trade and safety.

The relationship between free trade, self-sufficiency and safety of blood and blood components has been a perennial discussion topic in the blood service community. Traditionally, national self-sufficiency has been perceived as the ultimate goal that would also maximize safety. However, very few countries are, or can be, truly self-sufficient when self-sufficiency is understood correctly to encompass the whole value chain from the blood donor to the finished product. This is most striking when plasma derived medicines are considered. Free trade of blood products, or competition, as such can have a negative or positive effect on blood safety. Further, free trade of equipment and reagents and several plasma medicines is actually necessary to meet the domestic demand for blood and blood derivatives in most countries. Opposing free trade due to dogmatic reasons is not in the best interest of any country and will be especially harmful for the developing world. Competition between blood services in the USA has been present for decades. The more than threefold differences in blood product prices between European blood services indicate that competition is long overdue in Europe, too. This competition should be welcomed but carefully and proactively regulated to avoid putting safe and secure blood supply at risk. Copyright 2009 The International Association for Biologicals.

2012-07-01

Nowadays the availability of machine tools plays a decisive role in competition to increase in productivity. From state of the art it arises, that ball screw drives are the most abusive component in feed drives because of abrasive wear. Furthermore condition monitoring enables avoiding unplanned machine failure and increasing the availability of the deployed production facility. Thereby the application of additional sensors allows the direct acquisition of wear correlative measurements. To reduce the required effort for integration and increase the robustness, reliability and clarity in industrial environment energy self-sufficient sensor systems can be applied. In this thesis the development and investigation of an energy self-sufficient sensory ball screw drive with direct measurement of wear correlative pretension for condition monitoring application is described. The prototype measures the pretension with force sensors based on strain gauges. The sensor system includes microcontroller-based electronics for signal processing as well as wireless data transmission with ZigBee-standard. A hybrid system assures the energy supply of the sensor system. On the one hand a stepper motor generator produces electrical energy from the motion energy of the ball screw drive. On the other hand an energy buffer based on super caps is reloaded in stationary position by wireless energy transmission. For verification a prototype system is build up. In measurements the sensory and energetic characteristics of the energy self-sufficient sensor systems are analyzed. Moreover, the functionality of the ball screw drive as well as the signal characteristics of the force sensors are examined for different pretensions. In addition, pretension losses due to wear are established in realized endurance trials, which means that timely maintenance can be planned.

Sleep is an essential component of healthy cognitive and physical development. Lack of sleep may put children at risk for a variety of mental and physical health outcomes, including overweight, obesity and related chronic diseases. Given that children's sleep duration has decreased in recent decades, there is a need to understand the determinants of child sleep, including the role of parental support behaviours. This study aims to determine the relative contribution of different types of parental support behaviours for predicting the likelihood that children meet recently established Canadian sleep guidelines. Data were collected using Computer Assisted Telephone Interviews (CATI) of parents or guardians with at least one child under the age of 18 living in Ontario, Canada. To align with sleep guidelines, parents included in this analysis had at least one child between 5 and 17 years of age (n = 1622). Two multivariable logistic regression models were built to predict whether or not parents reported their child was meeting sleep guidelines - one for weekday sleep and another for sleep on weekends. Independent variables included parent and child age and gender, motivational and regulatory parental support behaviours, and socio-demographic characteristics. On weekdays, enforcing rules about child bedtime was a significant positive predictor of children meeting sleep guidelines (OR: 1.59; 95% CI: 1.03-2.44); while encouraging the child to go to bed at a specific time was a significant negative predictor of child meeting sleep guidelines (OR: 0.29; 95% CI: 0.13-0.65). On weekends, none of the parental support behaviours contributed significantly to the predictions of child sleep. For both weekdays and weekends, the child's age group was an important predictor of children meeting sleep guidelines. The contribution of parental support behaviours to predictions of children meeting sleep guidelines varied with the type of support provided, and weekend versus weekday

Highlights from an interview with Benjamin D. de Leon, who was appointed Presidential Assistant for Social Development in the Philippines in September 1992, are presented. Mr. de Leon's concern for the marginal sectors of society in health, employment, housing, social welfare, and manpower training as well as his goals of poverty alleviation and people empowerment account for this appointment. Duties include formulating a social development agenda; assisting the Social Development Committee of the Cabinet and the National Economic Development Authority (NEDA) in program implementation; and providing weekly information packages about family planning (FP), health, children, women, and the environment. The social development agenda of the Philippine Medium-term Plan (1992-1998) includes employment, income, wages; population, health and nutrition, and family planning; and housing, education, manpower development, social welfare, and community development. The Plan recognizes that poverty is aggravated by rapid population growth, and it strives to ensure that adolescents, military males, high-risk women, and young unmarried couples receive FP information and services from government agencies and nongovernmental organizations. Adequate resources for population and FP as well as recognizing the relationship among population, resources, and the environment are essential to meet the goals of the plan. The present population and FP policy is based on the 1987 Constitution, which spells out responsible parenthood but also rejects abortion as a method of contraception. The official FP program calls for child survival and safe motherhood and accessible, available, and affordable FP services. The Roman Catholic Church opposes the program, since the Church promotes only the rhythm method, but the other religions approve of the program. Some priests and nuns did not object to the promotion of FP. Sufficient financial support from the international community for the Philippine

We derive a sufficient condition for confinement of static quarks by a vortex condensation mechanism. It admits vortices that are thick at all times at the cost of constraining them to a finite volume Λi whose complement is not simply connected. The confining potential V(L) is estimated in terms of the change of free energy of a system enclosed in Λi which is induced by a change in vorticity (= singular gauge transformation applied to boundary conditions on deltaΛi). For Abelian gauge theories in 3 dimensions the confining Coulomb potential is reproduced as a lower bound. (orig.) [de

Enough is as good as a feast - sufficiency as policy

Energy Technology Data Exchange (ETDEWEB)

Darby, Sarah [Lower Carbon Futures, Environmental Change Inst., Oxford Univ. Centre for the Environment (United Kingdom)

2007-07-01

The concept of sufficiency has a long history, related as it is to the timeless issues of how best to distribute and use resources. Where energy is concerned, absolute reductions in demand are increasingly seen as necessary in response to climate change and energy security concerns. There is an acknowledgement that, collectively if not individually, humans have gone beyond safe limits in their use of fuels. The relatively wealthy and industrialised nations urgently need to move beyond a primary focus on efficiency to the more contentious issues surrounding demand reduction and sufficiency. The paper considers definitions of energy sufficiency, looks at a recent attempt to model future energy use in terms of efficiency and sufficiency, and discusses quantitative and qualitative aspects of sufficiency and how they might become institutionalised. There are many arguments in favour of sufficiency but they often founder in the face of political requirements for market growth and the employment generated by it. Some options for 'sufficiency policy' are selected, including a focus on energy in relation to livelihoods, energy implications of our use of time and making energy use more transparent.

There are operational difficulties in obtaining samples for radioecological studies. Population data may no longer be available during the study and obtaining new samples may not be possible. These problems do the researcher sometimes work with a small number of data. Therefore, it is difficult to know whether the number of samples will be sufficient to estimate the desired parameter. Hence, it is critical do the analysis of sample sufficiency. It is not interesting uses the classical methods of statistic to analyze sample sufficiency in Radioecology, because naturally occurring radionuclides have a random distribution in soil, usually arise outliers and gaps with missing values. The present work was developed aiming to apply the Monte Carlo Bootstrap method in the analysis of sample sufficiency with quantitative estimation of a single variable such as specific activity of a natural radioisotope present in plants. The pseudo population was a small sample with 14 values of specific activity of 226 Ra in forage palm (Opuntia spp.). Using the R software was performed a computational procedure to calculate the number of the sample values. The re sampling process with replacement took the 14 values of original sample and produced 10,000 bootstrap samples for each round. Then was calculated the estimated average θ for samples with 2, 5, 8, 11 and 14 values randomly selected. The results showed that if the researcher work with only 11 sample values, the average parameter will be within a confidence interval with 90% probability . (Author)

Muscle sufficiency was significantly lower in 1336 children with chronic malnutrition of moderate to severe degree. 18 children with a chronic moderate degree of malnutrition and 8 well-nourished age-matched controls were selected for biochemical and 31-phosphorus magnetic resonance spectroscopy (31-P MRS) studies. The results shows that: (a) serum total protein, albumin, iron, calcium and inorganic phosphate were similar in both groups; (b) serum enzyme levels were significantly increased in the malnuourished group; (c) 31-P MRS showed significantly higher means for total ATP, [beta]-ATP, [alpha]-ATP and inorganic phosphate for the malnourished compared to the control group. In chronic malnutrition, proteins are maintained by degradation in muscle resulting in release of amino acids and enzymes. 31-P MRS studies showing increases in total ATP, [beta]-ATP and inorganic phosphate and a decrease in phosphocreatine suggest that ATP is maintained at the cost of phosphocreatine. 22 refs., 4 tabs. 1 fig.

Exploring Societal Preferences for Energy Sufficiency Measures in Switzerland

2015-01-01

Many countries are facing a challenging transition toward more sustainable energy systems, which produce more renewables and consume less energy. The latter goal can only be achieved through a combination of efficiency measures and changes in people’s lifestyles and routine behaviors (i.e., sufficiency). While research has shown that acceptance of technical efficiency is relatively high, there is a lack of research on societal preferences for sufficiency measures. However, this is an important prerequisite for designing successful interventions to change behavior. This paper analyses societal preferences for different energy-related behaviors in Switzerland. We use an online choice-based conjoint analysis (N = 150) to examine preferences for behaviors with high technical potentials for energy demand reduction in the following domains: mobility, heating, and food. Each domain comprises different attributes across three levels of sufficiency. Respondents were confronted with trade-off situations evoked through different fictional lifestyles that comprised different combinations of attribute levels. Through a series of trade-off decisions, participants were asked to choose their preferred lifestyle. The results revealed that a vegetarian diet was considered the most critical issue that respondents were unwilling to trade off, followed by distance to workplace and means of transportation. The highest willingness to trade off was found for adjustments in room temperature, holiday travel behaviors, and living space. Participants’ preferences for the most energy-sufficient lifestyles were rather low. However, the study showed that there were lifestyles with substantive energy-saving potentials that were well accepted among respondents. Our study results suggest that the success of energy-sufficiency interventions might depend strongly on the targeted behavior. We speculate that they may face strong resistance (e.g., vegetarian diet). Thus, it seems promising to

Full Text Available Abstract Background Cerebral palsy (CP patients have motor limitations that can affect functionality and abilities for activities of daily living (ADL. Health related quality of life and health status instruments validated to be applied to these patients do not directly approach the concepts of functionality or ADL. The Child Health Assessment Questionnaire (CHAQ seems to be a good instrument to approach this dimension, but it was never used for CP patients. The purpose of the study was to verify the psychometric properties of CHAQ applied to children and adolescents with CP. Methods Parents or guardians of children and adolescents with CP, aged 5 to 18 years, answered the CHAQ. A healthy group of 314 children and adolescents was recruited during the validation of the CHAQ Brazilian-version. Data quality, reliability and validity were studied. The motor function was evaluated by the Gross Motor Function Measure (GMFM. Results Ninety-six parents/guardians answered the questionnaire. The age of the patients ranged from 5 to 17.9 years (average: 9.3. The rate of missing data was low (disability index with the visual analogue scales was not significant; for the convergent validity CHAQ disability index had a strong correlation with the GMFM (0.77; for the divergent validity there was no correlation between GMFM and the pain and overall evaluation scales; for the criterion validity GMFM as well as CHAQ detected differences in the scores among the clinical type of CP (p disability index score (mean:2.16; SD:0.72 was higher than the healthy group (mean:0.12; SD:0.23(p Conclusion CHAQ reliability and validity were adequate to this population.

Maternal education is strongly associated with young child nutrition outcomes. However, the threshold of the level of maternal education that reduces the level of undernutrition in children is not well established. This paper investigates the level of threshold of maternal education that influences child nutrition outcomes using Demographic and Health Survey data from Malawi (2010), Tanzania (2009-10) and Zimbabwe (2005-06). The total number of children (weighted sample) was 4,563 in Malawi; 4,821 children in Tanzania; and 3,473 children in Zimbabwe Demographic and Health Surveys. Using three measures of child nutritional status: stunting, wasting and underweight, we employ a survey logistic regression to analyse the influence of various levels of maternal education on child nutrition outcomes. In Malawi, 45% of the children were stunted, 42% in Tanzania and 33% in Zimbabwe. There were 12% children underweight in Malawi and Zimbabwe and 16% in Tanzania.The level of wasting was 6% of children in Malawi, 5% in Tanzania and 4% in Zimbabwe. Stunting was significantly (p values educational level in all the three countries. Higher levels of maternal education reduced the odds of child stunting, underweight and wasting in the three countries. The maternal threshold for stunting is more than ten years of schooling. Wasting and underweight have lower threshold levels. These results imply that the free primary education in the three African countries may not be sufficient and policies to keep girls in school beyond primary school hold more promise of addressing child undernutrition.

Research on the quality of life (QL) of children/adolescents with psychological disorders has flourished over the last few decades. Given the developmental challenges of QL measurements in pediatric populations, the aim of this study was to ascertain the extent to which a developmental approach to QL assessment has been applied to pedopsychiatric QL research. A systematic literature search was conducted in three electronic databases (PubMed, PsycINFO, SocINDEX) from 1994 to May 2014. Quantitative studies were included if they assessed the self- or proxy-reported QL of children/adolescents with a psychological disorder. Data were extracted for study design, participants, QL instruments and informants, and statistical approach to age-related specificities. The systematic review revealed widespread utilization of developmentally appropriate QL instruments but less frequent use of both self and proxy reports and an inconsistent approach to age group specificities. Methodological guidelines are discussed to improve the developmental validity of QL research for children/adolescents with mental disorders.

Applied behavior analysis: behavior management of children with autism spectrum disorders in dental environments.

Science.gov (United States)

Hernandez, Purnima; Ikkanda, Zachary

2011-03-01

There are a limited number of studies addressing behavior management techniques and procedural modifications that dentists can use to treat people with an autism spectrum disorder (ASD). The authors conducted a search of the dental and behavioral analytic literature to identify management techniques that address problem behaviors exhibited by children with ASDs in dental and other health-related environments. Applied behavior analysis (ABA) is a science in which procedures are based on the principles of behavior through systematic experimentation. Clinicians have used ABA procedures successfully to modify socially significant behaviors of people with ASD. Basic behavior management techniques currently used in dentistry may not encourage people with cognitive and behavioral disabilities, such as ASD, to tolerate simple in-office dental procedures consistently. Instead, dental care providers often are required to use advanced behavior management techniques to complete simple in-office procedures such as prophylaxis, sealant placement and obtaining radiographs. ABA procedures can be integrated in the dental environment to manage problem behaviors often exhibited by children with an ASD. The authors found no evidence-based procedural modifications that address the behavioral characteristics and problematic behaviors of children with an ASD in a dental environment. Further research in this area should be conducted. Knowledge and in-depth understanding of behavioral principles is essential when a dentist is concerned with modifying behaviors. Using ABA procedures can help dentists manage problem behaviors effectively and systematically when performing routine dental treatment. Being knowledgeable about each patient's behavioral characteristics and the parents' level of involvement is important in the successful integration of the procedures and reduction of in-office time.

Reassessing Rogers' necessary and sufficient conditions of change.

Science.gov (United States)

Watson, Jeanne C

2007-09-01

This article reviews the impact of Carl Rogers' postulate about the necessary and sufficient conditions of therapeutic change on the field of psychotherapy. It is proposed that his article (see record 2007-14630-002) made an impact in two ways; first, by acting as a spur to researchers to identify the active ingredients of therapeutic change; and, second, by providing guidelines for therapeutic practice. The role of the necessary and sufficient conditions in process-experiential therapy, an emotion-focused therapy for individuals, and their limitations in terms of research and practice are discussed. It is proposed that although the conditions are necessary and important in promoting clients' affect regulation, they do not take sufficient account of other moderating variables that affect clients' response to treatment and may need to be balanced with more structured interventions. Notwithstanding, Rogers highlighted a way of interacting with clients that is generally acknowledged as essential to effective psychotherapy practice.

1986-01-01

Conditions necessary to achieve deuterium-tritium fuel self-sufficiency in fusion reactors are derived through extensive modeling and calculations of the required and achievable tritium breeding ratios as functions of the many reactor parameters and candidate design concepts. It is found that the excess margin in the breeding potential is not sufficient to cover all present uncertainties. Thus, the goal of attaining fuel self-sufficiency significantly restricts the allowable parameter space and design concepts. For example, the required breeding ratio can be reduced by (A) attaining high tritium fractional burnup, >5%, in the plasma, (B) achieving very high reliability, >99%, and very short times, <1 day, to fix failures in the tritium processing system, and (C) ensuring that nonradioactive decay losses from all subsystems are extremely low, e.g., <0.1% for the plasma exhaust processing system. The uncertainties due to nuclear data and calculational methods are found to be significant, but they are substantially smaller than those due to uncertainties in system definition

Variable generation (VG) can reduce market prices over time and also the energy that other suppliers can sell in the market. The suppliers that are needed to provide capacity and flexibility to meet the long-term reliability requirements may, therefore, earn less revenue. This chapter discusses the topics of resource adequacy and revenue sufficiency - that is, determining and acquiring the quantity of capacity that will be needed at some future date and ensuring that those suppliers that offer the capacity receive sufficient revenue to recover their costs. The focus is on the investment time horizon and the installation of sufficient generation capability. First, the chapter discusses resource adequacy, including newer methods of determining adequacy metrics. The chapter then focuses on revenue sufficiency and how suppliers have sufficient opportunity to recover their total costs. The chapter closes with a description of the mechanisms traditionally adopted by electricity markets to mitigate the issues of resource adequacy and revenue sufficiency and discusses the most recent market design changes to address these issues.

Learn and apply: using multi-sensory storytelling to gather knowledge about preferences and abilities of children with profound intellectual and multiple disabilities--three case studies.

2013-12-01

Knowledge about the preferences and abilities of children with profound intellectual and multiple disabilities (PIMDs) is crucial for providing appropriate activities. Multi-sensory storytelling (MSST) can be an ideal activity for gathering such knowledge about children with PIMDs. The aim of this study was to analyse whether using MSST did lead to changes in teachers' knowledge about preferences and abilities and whether this knowledge was then applied in practice. Three dyads of children with PIMDs and their teachers read an MSST book 20 times during a 10-week period. A questionnaire designed to identify the teachers' current knowledge was filled in before the 1st and again after the 10th and 20th reading sessions. Also, the teachers were asked for their opinion about their newly gathered knowledge. In all three cases, changes in the teachers' knowledge were observed. However, teachers are insufficiently aware of their new knowledge and do not apply it in practice.

Applying Evolutionary Psychology to a Serious Game about Children's Interpersonal Conflict

Gordon P. D. Ingram

2012-12-01

Full Text Available This article describes the use of evolutionary psychology to inform the design of a serious computer game aimed at improving 9–12-year-old children's conflict resolution skills. The design of the game will include dynamic narrative generation and emotional tagging, and there is a strong evolutionary rationale for the effect of both of these on conflict resolution. Gender differences will also be taken into consideration in designing the game. In interview research in schools in three countries (Greece, Portugal, and the UK aimed at formalizing the game requirements, we found that gender differences varied in the extent to which they applied cross-culturally. Across the three countries, girls were less likely to talk about responding to conflict with physical aggression, talked more about feeling sad about conflict and about conflicts over friendship alliances, and talked less about conflicts in the context of sports or games. Predicted gender differences in anger and reconciliation were not found. Results are interpreted in terms of differing underlying models of friendship that are motivated by parental investment theory. This research will inform the design of the themes that we use in game scenarios for both girls and boys.

This study compared a common form of Applied Behavior Analysis Verbal Behavior (ABA VB) approach and music incorporated with ABA VB method as part of developmental speech-language training in the speech production of children with Autism Spectrum Disorders (ASD). This study explored how the perception of musical patterns incorporated in ABA VB operants impacted the production of speech in children with ASD. Participants were 22 children with ASD, age range 3 to 5 years, who were verbal or pre verbal with presence of immediate echolalia. They were randomly assigned a set of target words for each of the 3 training conditions: (a) music incorporated ABA VB, (b) speech (ABA VB) and (c) no-training. Results showed both music and speech trainings were effective for production of the four ABA verbal operants; however, the difference between music and speech training was not statistically different. Results also indicated that music incorporated ABA VB training was most effective in echoic production, and speech training was most effective in tact production. Music can be incorporated into the ABA VB training method, and musical stimuli can be used as successfully as ABA VB speech training to enhance the functional verbal production in children with ASD.

Children, because of age-related reasons, are a vulnerable population, and protecting their health is a social, scientific and emotional priority. The increased susceptibility of children and fetuses to environmental (including genotoxic) agents has been widely discussed by the scientific community. Children may experience different levels of chemical exposure than adults, and their sensitivity to chemical toxicities may be increased or decreased in comparison with adults. Such considerations also apply to unborn (fetal exposure) and newborn (neonatal exposure) children. Therefore, research on children is necessary in both clinical and environmental fields, to provide age-specific relevant data regarding the efficacy and safety of medical treatments, and regarding the assessment of risk from unintended environmental exposure. In this context, the stakeholders are many, including children and their parents, physicians and public health researchers, and the society as a whole, with its ethical, regulatory, administrative and political components. The important ethical issues are information of participants and consent to participate. Follow-up and protection of data (samples and information derived from samples) should be discussed in the context of biobanks, where children obtain individual rights when they become adults. It is important to realise that there are highly variable practices within European countries, which may have, in the past, led to differences in practical aspects of research in children. A number of recommendations are provided for research with children and environmental health. Environmental research with children should be scientifically justified, with sound research questions and valid study protocols of sufficient statistical power, ensuring the autonomy of the child and his/her family at the time of the study and later in life, if data and samples are used for follow-up studies. When children are enrolled, we recommend a consent dyad

Transforming the energy system: Why municipalities strive for energy self-sufficiency

2016-01-01

Despite evidence that a rising number of municipalities in Germany are striving for energy self-sufficiency, there is little understanding of the driving factors behind this development. We investigate economic, ecological, social and energy system related factors that drive municipalities to strive for energy self-sufficiency with a focus on electricity supply. The empirical data for this study is based on insights generated through expert interviews (N =19) with mayors, energy experts and scientists as well as a quantitative study among mayors and energy officers (N =109) of German municipalities. Results show that environmental awareness, tax revenues and greater independence from private utilities are positively related to the mayors’ attitude towards the realization of energy self-sufficiency. Furthermore, citizens, the political environment, the mayor's political power, and his/her financial resources are relevant factors for a municipality striving for energy self-sufficiency. Policymakers need to decide whether or not to support mayors in this development. For suitable policy interventions, the results suggest the importance of an integrated approach that considers a combination of identified factors. Finally, we propose a morphological box to structure different aspects of energy self-sufficiency and categorize the present study. - Highlights: • Municipalities striving for energy self-sufficiency can play a key role in the transition of the energy system. • Tax revenues and environmental awareness main drivers behind mayors’ attitude towards energy self-sufficiency. • Citizens and the political environment main influencers of mayors striving for energy self-sufficiency. • 19 expert interviews analyzed for the framework of the study based on the theory of planned behavior (TPB). • 109 mayors and energy officers participated in the quantitative main survey.

Current methods for assessment of iodine intake in a population comprise measurements of urinary iodine concentration (UIC), thyroid volume by ultrasound (US-Tvol), and newborn TSH. Serum or dried blood spot thyroglobulin (DBS-Tg) is a new promising functional iodine status biomarker in children. In 1996, a new act on universal salt iodination was introduced in Croatia with 25 mg of potassium iodideper kg of salt. In 2002, Croatia finally reached iodine sufficiency. However, in 2009, median UIC in 101 schoolchildren from Zagreb, the capital of Croatia, was 288 µg/L, posing to be excessive. The aim of the study was to assess iodine intake in schoolchildren from the Zagreb area and to evaluate the value of DBS-Tg in schoolchildren as a new functional biomarker of iodine deficiency (and iodine excess). The study was part of a large international study in 6- to 12-year-old children supported by UNICEF, the Swiss Federal Institute of Technology (ETH Zurich) and the International Council for the Control of Iodine Deficiency Disorders (ICCIDD). According to international study results, the median cut-off Tg 40 µg/L indicate iodine sufficiency. The study included 159 schoolchildren (median age 9.1 ± 1.4 years) from Zagreb and a nearby small town of Jastrebarsko with measurements of UIC, US-Tvol, DBS-Tg, T4, TSH and iodine content in salt from households of schoolchildren (KI/kg of salt). Overall median UIC was 205 µg/L (range 1-505 µg/L). Thyroid volumes in schoolchildren measured by US were within the normal range according to reference values. Median DBS-Tg in schoolchildren was 12.1 µg/L with 3% of Tg values > 40 µg/L. High Tg values were in the UIC range 300 µg/L (U-shaped curve of Tg plotted against UIC). All children were euthyroid with geometric mean TSH 0.7 ± 0.3 mU/L and arithmetic mean T4 62 ± 12.5 nmol/L. The mean KI content per kg of salt was 24.9 ± 3.1 mg/kg (range 19-36 mg/kg).

2015-09-01

Full Text Available Multiple individual, social, and environmental factors have long been recognized as influencing a child’s response to traumatic experiences. However, there remain few socio-ecological frameworks to guide researchers and practitioners working with war-affected children. This article examines Silove’s psychosocial model of adaptation and development after trauma and persecution (ADAPT model in relation to war-affected children. The utility of the model is explored by examining whether the systems of safety, attachment, identity, justice, and existential meaning described in the ADAPT model are represented in a narrative review of research from the last 20 years on the experiences of war-affected children and adolescents. Results suggest that research with war-affected children has covered all five psychosocial pillars in the model, but with overemphasis on the safety, followed by the attachment, domains. This review highlights that need for research and psychosocial interventions that focus on adaptation of war-affected children’s identity development, sense of justice, and meaning systems.

The concept of sufficiency has a long history, related as it is to the timeless issues of how best to distribute and use resources. Where energy is concerned, absolute reductions in demand are increasingly seen as necessary in response to climate change and energy security concerns. There is an acknowledgement that, collectively if not individually, humans have gone beyond safe limits in their use of fuels. The relatively wealthy and industrialised nations urgently need to move beyond a primary focus on efficiency to the more contentious issues surrounding demand reduction and sufficiency. The paper considers definitions of energy sufficiency, looks at a recent attempt to model future energy use in terms of efficiency and sufficiency, and discusses quantitative and qualitative aspects of sufficiency and how they might become institutionalised. There are many arguments in favour of sufficiency but they often founder in the face of political requirements for market growth and the employment generated by it.

Currently no tools to predict risk of acute (AP) and recurrent pancreatitis (ARP) in children with cystic fibrosis (CF) are available. We assessed the prevalence of AP/ARP and tested the potential role of Pancreatic Insufficiency Prevalence (PIP) score in a cohort of children with CF. We identified two groups of children, on the basis of presence/absence of AP/ARP, who were compared for age at diagnosis, clinical features, genotypes and sweat chloride level. PIP score was calculated for each patient. 10/167 (5.9%) experienced at least one episode of AP during follow up; 10/10 were pancreatic sufficient (PS). Patients with AP/ARP showed a PIP score ≤0.25 more frequently (6/10) than patients without AP/ARP. The odds ratio (95% CI) of developing pancreatitis was 4.54 (1.22-16.92) for patients with PIP 0.25 (p 0.0151). PIP score was correlated with sweat chloride test (p < 0.01). PIP score, PS status and normal/borderline sweat chloride levels could be applied to predict pancreatitis development in children with CF. ARP could lead to pancreatic insufficiency.

Revenue insufficiency, or the missing money problem, occurs when the revenues that generators earn from the market are not sufficient to cover both fixed and variable costs to remain in the market and/or justify investments in new capacity, which may be needed for reliability. The near-zero marginal cost of variable renewable generators further exacerbates these revenue challenges. Estimating the extent of the missing money problem in current electricity markets is an important, nontrivial task that requires representing both how the power system operates and how market participants behave. This paper explores the missing money problem using a production cost model that represented a simplified version of the Electric Reliability Council of Texas (ERCOT) energy-only market for the years 2012-2014. We evaluate how various market structures -- including market behavior, ancillary services, and changing fleet compositions -- affect net revenues in this ERCOT-like system. In most production cost modeling exercises, resources are assumed to offer their marginal capabilities at marginal costs. Although this assumption is reasonable for feasibility studies and long-term planning, it does not adequately consider the market behaviors that impact revenue sufficiency. In this work, we simulate a limited set of market participant strategic bidding behaviors by means of different sets of markups; these markups are applied to the true production costs of all gas generators, which are the most prominent generators in ERCOT. Results show that markups can help generators increase their net revenues overall, although net revenues may increase or decrease depending on the technology and the year under study. Results also confirm that conventional, variable-cost-based production cost simulations do not capture prices accurately, and this particular feature calls for proxies for strategic behaviors (e.g., markups) and more accurate representations of how electricity markets work.

Philosophy of sufficiency economy for community-based adaptation to climate change: Lessons learned from Thai case studies

Directory of Open Access Journals (Sweden)

Kulvadee Kansuntisukmongkol

2017-01-01

Full Text Available Major components within the philosophy of a sufficiency economy include moderation, prudence, and self-immunity together with knowledge and morality. These components were proposed to safeguard local communities from adverse changes and crises. Climatic crises due to global warming can impact upon local agricultural production and consumption systems. Yet, it is still questionable whether communities following the sufficiency economy philosophy can cope with climate change. The objective of this research was to study the coping and adaptive capacity to climate change of local agricultural communities following the sufficiency economy philosophy and to analyze the success factors of adaptation to climate change. The research found five adaptive strategies leading to a resilient livelihood: (1 self-evaluation, (2 diversity dependency, (3 storage and reserve, (4 cooperation, and (5 mobility over space and time. These strategies help to reduce exposure and sensitivity, while increasing adaptive capacity to climate change with the aims of sustainability and adaptation for survival, and protecting natural resource bases for food and settlement security. Moderation, prudence, and self-immunity are critical success factors of adaptation measures, whereas local ecological knowledge with morality is a core enabling factor for adapting to climate change. These factors can be applied in community-based climate change adaptation in the National Adaptation Plan.

Anaesthesia allows imaging to be optimised but it is expensive, scarce and inappropriate for many situations. Fortunately, sedation and behavioural techniques are sufficiently successful for the majority of scanning, and success rates are high provided that suitable children are selected. Sedation, however, administered by non-anaesthetists, may have catastrophic complications such as airway obstruction. Current UK recommendations demand that any sedation technique has a 'wide margin of safety', but in addition to this, safety is dependent on trained, skilful and experienced staff. Magnetic resonance imaging frightens many children and special planning is necessary for sedation and anaesthesia. When planning an imaging service for children, all the management techniques should be considered in order to achieve maximum efficiency, quality and safety

Quantification is Neither Necessary Nor Sufficient for Measurement

Being an infrastructural, widespread activity, measurement is laden with stereotypes. Some of these concern the role of measurement in the relation between quality and quantity. In particular, it is sometimes argued or assumed that quantification is necessary for measurement; it is also sometimes argued or assumed that quantification is sufficient for or synonymous with measurement. To assess the validity of these positions the concepts of measurement and quantitative evaluation should be independently defined and their relationship analyzed. We contend that the defining characteristic of measurement should be the structure of the process, not a feature of its results. Under this perspective, quantitative evaluation is neither sufficient nor necessary for measurement

The level of energy sufficiency - why all the controversy?

International Nuclear Information System (INIS)

Maillard, D.

2000-01-01

It as become fashionable in certain circles to attempt to demolish the notion of energy sufficiency, a concept which is now seen as being archaic and unsuitable. To back up their claims, proponents of this standpoint take great pleasure in attacking the corresponding indicator - the rate of energy sufficiency calculated as a ratio of national primary energy production and the total consumption of primary energy (in the same unit and without climatic corrections). Confirming its precarious, conventional and debatable nature seems in their eyes to be the best means of ensuring that both the word, the concept and the measuring method of energy sufficiency are consigned to the dustbin of economic history. After having examined with perhaps a certain irony some of the usual criticisms, I intend to proceed with a re-examination of questions which in my eyes appear to be essential. (author)

Children and adolescents referred for treatment of anxiety disorders: differences in clinical characteristics.

Science.gov (United States)

Waite, Polly; Creswell, Cathy

2014-01-01

Reports of the clinical characteristics of children and adolescents with anxiety disorders are typically based on community populations or from clinical samples with exclusion criterion applied. Little is known about the clinical characteristics of children and adolescents routinely referred for treatment for anxiety disorders. Furthermore, children and adolescents are typically treated as one homogeneous group although they may differ in ways that are clinically meaningful. A consecutive series of children (n=100, aged 6-12 years) and adolescents (n=100, aged 13-18 years), referred to a routine clinical service, were assessed for anxiety and comorbid disorders, school refusal and parental symptoms of psychopathology. Children with a primary anxiety disorder were significantly more likely to be diagnosed with separation anxiety disorder than adolescents. Adolescents with a primary anxiety disorder had significantly higher self and clinician rated anxiety symptoms and had more frequent primary diagnoses of social anxiety disorder, diagnoses and symptoms of mood disorders, and irregular school attendance. Childhood and adolescence were considered categorically as distinct, developmental periods; in reality changes would be unlikely to occur in such a discrete manner. The finding that children and adolescents with anxiety disorders have distinct clinical characteristics has clear implications for treatment. Simply adapting treatments designed for children to make the materials more 'adolescent-friendly' is unlikely to sufficiently meet the needs of adolescents. Copyright © 2014 The Authors.

Full Text Available The concept of economic self-reliance, widely known by Thai people as the philosophy of sufficiency economy, has been widely promoted in rural Thai societies. By practicing this philosophy, it is expected that the citizens’ quality of life and local environments could be sustainably improved. This study aims to explore the contribution of the community practices of the sufficiency economy philosophy to rural villagers’ quality of life improvement, and to investigate potential factors that determine the trust of villagers in the philosophy. With the purpose to propose strategies which could enhance trust and promote villagers’ practices of the philosophy, the study investigated influences of three relevant factors on trust towards the philosophy. Those factors included factors related to cognitive-based trust, factors related to emotional-based trust, and factors related to demographic characteristics. Questionnaire surveys and in-depth interviews with community leaders and local villagers were conducted in the Ban Jamrung community, in Thailand’s Rayong Province. The results of the statistical analysis revealed that the residents who applied the sufficiency economy philosophy in their daily lives experienced a relatively better quality of life. Additionally, it was found that trust in the philosophy could be predicted more by rational factors than by emotional factors. These findings could be utilized to develop strategies to maintain and enhance the trust of the people in the philosophy of sufficiency economy.

The problem of education of culture of health in children ofpreschool age is actual and sufficiently complicated. It is important at this age stage to create in children the first knowledge and practical skills of a healthy lifestyle. The example of parents has considerable impact on adoption of health saving behavior of a child. For identification of motivations of parents in the sphere of protection and strengthening of health of their children there was performed questionnaire survey of parents of preschool children according to specially developed questionnaire. A half of parents are established to be unable to devote sufficient time to health of the child due to engrossment. A considerable portion of parents doesn't keep a healthy lifestyle, differs in low medical and sports activity. The main motivation of parents is the motivation on recovery of the child after the disease, but not on preservation, strengthening and development of health.

Video modeling using applied behavior analysis techniques is one of the most promising and cost-effective ways to improve social skills for parents with autism spectrum disorder children. The main objectives were: (1) To elaborate/describe videos to improve eye contact and joint attention, and to decrease disruptive behaviors of autism spectrum disorder children, (2) to describe a low-cost parental training intervention, and (3) to assess participant's compliance. This is a descriptive study of a clinical trial for autism spectrum disorder children. The parental training intervention was delivered over 22 weeks based on video modeling. Parents with at least 8 years of schooling with an autism spectrum disorder child between 3 and 6 years old with an IQ lower than 70 were invited to participate. A total of 67 parents fulfilled the study criteria and were randomized into two groups: 34 as the intervention and 33 as controls. In all, 14 videos were recorded covering management of disruptive behaviors, prompting hierarchy, preference assessment, and acquisition of better eye contact and joint attention. Compliance varied as follows: good 32.4%, reasonable 38.2%, low 5.9%, and 23.5% with no compliance. Video modeling parental training seems a promising, feasible, and low-cost way to deliver care for children with autism spectrum disorder, particularly for populations with scarce treatment resources.

Sufficient luminal distension is mandatory for small bowel imaging. However, patients often are unable to ingest volumes of currently applied oral contrast compounds. The aim of this study was to evaluate if administration of low doses of an oral contrast agent with high-osmolarity leads to sufficient and diagnostic bowel distension. Six healthy volunteers ingested at different occasions 150, 300 and 450 ml of a commercially available oral contrast agent (Banana Smoothie Readi-Cat, E-Z-EM; 194 mOsmol/l). Two-dimensional TrueFISP data sets were acquired in 5-min intervals up to 45 min after contrast ingestion. Small bowel distension was quantified using a visual five-grade ranking (5 very good distension, 1 = collapsed bowel). Results were statistically compared using a Wilcoxon-Rank test. Ingestion of 450 ml and 300 ml resulted in a significantly better distension than 150 ml. The all-over average distension value for 450 ml amounted to 3.4 (300 ml: 3.0, 150 ml: 2.3) and diagnostic bowel distension could be found throughout the small intestine. Even 45 min after ingestion of 450 ml the jejunum and ileum could be reliably analyzed. Small bowel imaging with low doses of contrast leads to diagnostic distension values in healthy subjects when a high-osmolarity substance is applied. These findings may help to further refine small bowel MRI techniques, but need to be confirmed in patients with small bowel disorders. (orig.)

Epidemiological Paradox or Immigrant Vulnerability? Obesity Among Young Children of Immigrants

Science.gov (United States)

Baker, Elizabeth H.; Rendall, Michael S.; Weden, Margaret M.

2015-01-01

According to the “immigrant epidemiological paradox,” immigrants and their children enjoy health advantages over their U.S.-born peers—advantages that diminish with greater acculturation. We investigated child obesity as a potentially significant deviation from this paradox for second-generation immigrant children. We evaluated two alternate measures of mother's acculturation: age at arrival in the United States and English language proficiency. To obtain sufficient numbers of second-generation immigrant children, we pooled samples across two related, nationally representative surveys. Each included measured (not parent-reported) height and weight of kindergartners. We also estimated models that alternately included and excluded mother's pre-pregnancy weight status as a predictor. Our findings are opposite to those predicted by the immigrant epidemiological paradox: children of U.S.-born mothers were less likely to be obese than otherwise similar children of foreign-born mothers; and the children of the least-acculturated immigrant mothers, as measured by low English language proficiency, were the most likely to be obese. Foreign-born mothers had lower (healthier) pre-pregnancy weight than U.S.-born mothers, and this was protective against their second-generation children's obesity. This protection, however, was not sufficiently strong to outweigh factors associated or correlated with the mothers' linguistic isolation and marginal status as immigrants. PMID:26111970

1995-01-01

Lawrence Livermore National Laboratory (LLNL) and the U.S. Department of Energy, Oakland Field Office (DOE/OAK), are participating in a pilot program to evaluate the process to develop necessary and sufficient sets of standards for contractor activities. This concept of contractor and DOE jointly and locally deciding on what constitutes the set of standards that are necessary and sufficient to perform work safely and in compliance with federal, state, and local regulations, grew out of DOE's Department Standards Committee (Criteria for the Department's Standards Program, August 1994, DOE/EH/-0416). We have chosen radioactive waste management activities as the pilot program at LLNL. This pilot includes low-level radioactive waste, transuranic (TRU) waste, and the radioactive component of low-level and TRU mixed wastes. Guidance for the development and implementation of the necessary and sufficient set of standards is provided in open-quotes The Department of Energy Closure Process for Necessary and Sufficient Sets of Standards,close quotes March 27, 1995 (draft)

Treatments of pediatric feeding disorders based on applied behavior analysis (ABA) have the most empirical support in the research literature (Volkert & Piazza, 2012); however, professionals often recommend, and caregivers often use, treatments that have limited empirical support. In the current investigation, we compared a modified sequential oral sensory approach (M-SOS; Benson, Parke, Gannon, & Muñoz, 2013) to an ABA approach for the treatment of the food selectivity of 6 children with autism. We randomly assigned 3 children to ABA and 3 children to M-SOS and compared the effects of treatment in a multiple baseline design across novel, healthy target foods. We used a multielement design to assess treatment generalization. Consumption of target foods increased for children who received ABA, but not for children who received M-SOS. We subsequently implemented ABA with the children for whom M-SOS was not effective and observed a potential treatment generalization effect during ABA when M-SOS preceded ABA. © 2016 Society for the Experimental Analysis of Behavior.

Sufficient conditions for positivity of non-Markovian master equations with Hermitian generators

International Nuclear Information System (INIS)

Wilkie, Joshua; Wong Yinmei

2009-01-01

We use basic physical motivations to develop sufficient conditions for positive semidefiniteness of the reduced density matrix for generalized non-Markovian integrodifferential Lindblad-Kossakowski master equations with Hermitian generators. We show that it is sufficient for the memory function to be the Fourier transform of a real positive symmetric frequency density function with certain properties. These requirements are physically motivated, and are more general and more easily checked than previously stated sufficient conditions. We also explore the decoherence dynamics numerically for some simple models using the Hadamard representation of the propagator. We show that the sufficient conditions are not necessary conditions. We also show that models exist in which the long time limit is in part determined by non-Markovian effects

Role of exponential type random invexities for asymptotically sufficient efficiency conditions in semi-infinite multi-objective fractional programming.

Science.gov (United States)

Verma, Ram U; Seol, Youngsoo

2016-01-01

First a new notion of the random exponential Hanson-Antczak type [Formula: see text]-V-invexity is introduced, which generalizes most of the existing notions in the literature, second a random function [Formula: see text] of the second order is defined, and finally a class of asymptotically sufficient efficiency conditions in semi-infinite multi-objective fractional programming is established. Furthermore, several sets of asymptotic sufficiency results in which various generalized exponential type [Formula: see text]-V-invexity assumptions are imposed on certain vector functions whose components are the individual as well as some combinations of the problem functions are examined and proved. To the best of our knowledge, all the established results on the semi-infinite aspects of the multi-objective fractional programming are new, which is a significantly new emerging field of the interdisciplinary research in nature. We also observed that the investigated results can be modified and applied to several special classes of nonlinear programming problems.

Vitamins K and D are important for the function of vitamin K-dependent proteins in joint tissues. It is unclear if these nutrients are mutually important to functional outcomes related to knee osteoarthritis (OA). We evaluated the association of vitamin K and D sufficiency with lower-extremity function in the Health, Aging Body Composition Knee OA Sub-study (Health ABC) and conducted a replication analysis in an independent cohort, the Osteoarthritis Initiative (OAI). In Health ABC (60% female, 75±3 years) baseline nutrient status was measured using circulating vitamin K and 25(OH)D. Lower-extremity function was assessed using the short physical performance battery (SPPB) and usual 20-meter gait speed. In the OAI (58% female, 61±9 years), baseline nutrient intake was estimated by food frequency questionnaire. Lower-extremity function was assessed using usual 20-meter gait speed and chair stand completion time. Multivariate mixed models were used to evaluate the association of vitamin K and D status and intake with lower-extremity function over 4-5 years. Health ABC participants with sufficient plasma vitamin K (≥1.0 nmol/L) and serum 25(OH)D (≥50 nmol/L) generally had better SPPB scores and faster usual gait speed over follow-up (p≤0.002). In the OAI, sufficient vitamin K and vitamin D intake combined was associated with overall faster usual gait speed and chair stand completion time over follow-up (p≤0.029). Sufficient vitamin K status combined with sufficient vitamin D status was associated with better lower-extremity function in two knee OA cohorts. These findings merit confirmation in vitamin K and D co-supplementation trials. This article is protected by copyright. All rights reserved. This article is protected by copyright.

EVALUATION OF FOOD SELF-SUFFICIENCY OF THE REPUBLIC OF TATARSTAN DISTRICTS

Directory of Open Access Journals (Sweden)

R. E. Mansurov

2017-01-01

Full Text Available The article presents the author's method for estimation of the level of food self-sufficiency for the main types of food products in the regions of Republic of Tatarstan. The proposed method is based on the use of analytical methods and mathematical comparative analysis to compose a final rating. The proposed method can be used in the system of regional management of agro-industrial complex on the federal and local level. Relevance. The relevance of this work is caused by on the one hand a hardening of foreign policy that may negatively impact on national food security, and on the other hand the state crisis of the domestic agricultural sector. All this requires the development of new approaches to regional agribusiness management. Goal. To develop a methodology is used to assess the level of food self-sufficiency. To rate the level of self-sufficiency in main types of foodstuff in regions of Republic of Tatarstan. Materials and Methods. Statistical data of the results of the AIC of the Republic of Tatarstan for 2016 was used for the study. Analytical methods, including mathematical analysis and comparison were used. Results. Based on the analysis of the present situation for ensuring of food security in Russia it was shown that now it is necessary to develop effective indicators identifying the level of self-sufficiency in basic food regions. It was also revealed that there are no such indicators in system of regional agrarian and industrial complex at present time. As a result of analysis existing approaches the author's method of rating the level of self-sufficiency of regions was offered. This method was adopted on the example of the Republic of Tatarstan. Conclusions. The proposed method of rating estimation of self-sufficiency for basic foodstuffs can be used in the regional agroindustrial complex management system at the federal and local level. It can be used to rank areas in terms of their self-sufficiency for basic foodstuffs. This

Global Sufficient Optimality Conditions for a Special Cubic Minimization Problem

Directory of Open Access Journals (Sweden)

Xiaomei Zhang

2012-01-01

Full Text Available We present some sufficient global optimality conditions for a special cubic minimization problem with box constraints or binary constraints by extending the global subdifferential approach proposed by V. Jeyakumar et al. (2006. The present conditions generalize the results developed in the work of V. Jeyakumar et al. where a quadratic minimization problem with box constraints or binary constraints was considered. In addition, a special diagonal matrix is constructed, which is used to provide a convenient method for justifying the proposed sufficient conditions. Then, the reformulation of the sufficient conditions follows. It is worth noting that this reformulation is also applicable to the quadratic minimization problem with box or binary constraints considered in the works of V. Jeyakumar et al. (2006 and Y. Wang et al. (2010. Finally some examples demonstrate that our optimality conditions can effectively be used for identifying global minimizers of the certain nonconvex cubic minimization problem.

AIM: Predictive equations for estimating body composition from bioelectrical impedance analysis (BIA) among Scandinavian children are lacking. In the present study, equations for estimation of fat-free body mass (FFM) and lean tissue mass (LTM) were developed and cross-validated from BIA using dual...... linear regression and cross-validated against DXA measurements of body composition. RESULTS: FFM was predicted from BIA and anthropometric variables with an adjusted R(2)= 0.95 and root mean square error (RMSE) = 0.84 kg, and LTM was predicted with an adjusted R(2)= 0.95 and RMSE = 0.87 kg. Cross......-validation revealed a mean RMSE = 0.95 kg FFM and a mean RMSE = 0.96 kg LTM. Prediction of body composition from equations developed in previous literature was mixed when applied to the present cohort of children. CONCLUSIONS: FFM and LTM are predicted with sufficient accuracy at the population level. We recommend...

Autonomy of the child in the South African context: is a 12 year old of sufficient maturity to consent to medical treatment?

Science.gov (United States)

Ganya, Wandile; Kling, Sharon; Moodley, Keymanthri

2016-11-02

A child is a developing person with evolving capacities that include autonomy, mental (decisional) capacity and capacity to assume responsibility. Hence, children are entitled to participatory (autonomy) rights in South Africa as observed in the Children's Act 38 of 2005. According to section 129 of the Act a child may consent to his or her own medical treatment provided that he or she is over the age of 12 years and is of sufficient maturity and decisional capacity to understand the various implications of the treatment including the risks and benefits thereof. However, the Act does not provide a definition for what qualifies as 'sufficient maturity' nor does it stipulate how health professionals ought to assess the decisional capacity of a child. In addition, South Africa is a culturally diverse country. The Western liberal notion of autonomy may not necessarily find equal prominence in the mores of people with a different worldview. Hence we demonstrate a few salient comparisons between legal liberal moral theory and African communitarianism as pertinent to the autonomy of the child. Children are rights-holders by virtue of their humanity. Their dignity as individual human persons affords them the entitlement to human rights as contemplated under the Constitution of the Republic of South Africa. However, contrary to the traditional Western notion of individual autonomous persons African societies hold a communalistic notion of person hence there is less regard for individual autonomy and rights with more emphasis on the communal good and maintaining the continuity of relationships and interdependencies shared within a community. A child considered in this view is not regarded as a full person. This implies that decisions concerning the child, including consent to medical treatment are discussed and determined by the community to which the child belongs. Lastly, in this article, we draw on the notion of capacity for responsibility to produce a pragmatic

How to apply SHA 2011 at a subnational level in China's practical situation: take children health expenditure as an example.

System of Health Accounts 2011 (SHA 2011) is a new health care accounts system, revised from SHA 1.0 by the Organisation for Economic Co-operation and Development (OECD), the World Health Organization (WHO) and Eurostat. It keeps the former tri-axial relationship and develops three analytical interfaces, in order to fix the existing shortcomings and make it more convenient for analysis and comparison across countries. SHA 2011 was introduced in China in 2014, and little about its application in China has been reported. This study takes children as an example to study how to apply SHA 2011 at the subnational level in the practical situation of China's health system. Multistage random sampling method was applied and 3 532 517 samples from 252 institutions were included in the study. Official yearbooks and account reports helped the estimation of provincial data. The formula to calculate Current Health Expenditure (CHE) was introduced step-by-step. STATA 10.0 was used for statistics. Under the frame of SHA 2011, the CHE for children in Liaoning was calculated as US$ 0.74 billion in 2014; 98.56% of the expenditure was spent in hospital and the allocation to primary health care institutions was insufficient. Infection, maternal and prenatal diseases cost the most in terms of Global Burden of Disease (GBD), and respiratory system diseases took the leading place in terms of International Classification of Disease Tenth Revision (ICD-10). In addition, medical income contributed most to the health financing. The method to apply SHA 2011 at the subnational level is feasible in China. It makes health accounts more adaptable to rapidly developing health systems and makes the financing data more readily available for analytical use. SHA 2011 is a better health expenditure accounts system to reveal the actual burden on residents and deserves further promotion in China as well as around the world.

Applying surveillance and screening to family psychosocial issues: implications for the medical home.

Science.gov (United States)

Garg, Arvin; Dworkin, Paul H

2011-06-01

Within the medical home, understanding the family and community context in which children live is critical to optimally promoting children's health and development. How to best identify psychosocial issues likely to have an impact on children's development is uncertain. Professional guidelines encourage pediatricians to incorporate family psychosocial screening within the context of primary care, yet few providers routinely screen for these issues. The authors propose applying the core principles of surveillance and screening, as applied to children's development and behavior, to also address family psychosocial issues during health supervision services. Integrating psychosocial surveillance and screening into the medical home requires changes in professional training, provider practice, and public policy. The potential of family psychosocial surveillance and screening to promote children's optimal development justifies such changes.

POLITICAL ECONOMIC ANALYSIS OF RICE SELF-SUFFICIENCY IN INDONESIA

Directory of Open Access Journals (Sweden)

Sri Nuryanti

2018-01-01

Full Text Available Rice self-sufficiency is an important programme in Indonesia. The programme has four major targets, i.e. increasing production, stabilizing prices and reserve stocks, and minimizing import. For that purpose, the government gave a mandate to a parastatal, namely National Logistic Agency (Bulog in implementing the rice policies. Some studies found that involvement of such a parastatal could lead to government failure in budget allocation. The study aimed to estimate social cost of rice self-sufficiency programme based on the implementation of rice instrument policies by Bulog. The study used the national annual data of 2002–2014 period. The method used was the political preference function model to estimate economic rent and dead-weight loss using rice price elasticity of demand and supply. The result showed that in terms of percentage of food security budget, the average of economic rent reached IDR 6.37 trillion per annum (18.54%, while the average of dead-weight loss amounted at IDR 0.90 trillion per annum (2.34%. It proved that rice self-sufficiency programme along with the involvement of Bulog was economically inefficient. The government should provide better agricultural infrastructure, review governmental procurement prices, and stop rice import policy to remedy market failure.

The sufficiency of 169 athletes (six disciplines: bullet shooting, biathlon, bobsleigh, skeleton, freestyle skiing, snowboarding) with vitamins A, E, C, B2, and beta-carotene has been investigated in April-September 2013. All athletes (102 juniors, mean age--18.5 +/- 0.3 years, and 67 adult high-performance athletes, mean age--26.8 +/- 0.7 years) were sufficiently supplied with vitamin A (70.7 +/- 1.7 mcg/dl). Mean blood serum retinol level was 15% higher the upper limit of the norm (80 mcg/dl) in biathletes while median reached 90.9 mcg/dl. Blood serum level of tocopherols (1.22 +/- 0.03 mg/dl), ascorbic acid (1.06 +/- 0.03 mg/dl), riboflavin (7.1 +/- 0.4 ng/ml), and beta-carotene (25.1 +/- 1.7 mcg/dl) was in within normal range, but the incidence of insufficiency of vitamins E, C, B2, and carotenoid among athletes varied in the range of 0-25, 0-17, 15-67 and 42-75%, respectively. 95% of adults and 80% of younger athletes were sufficiently provided with vitamin E. Vitamin E level in blood serum of juniors involved in skeleton and biathlon was lower by 51 and 72% (p antioxidants (beta-carotene and vitamins E and C). In other sports, the relative quantity of athletes sufficiently supplied with these essential nutrients did not exceed 56%. The quota of supplied with all antioxidants among bullet shooters (31.1%) and bobsledders (23.5%) was significantly (p antioxidant (mainly beta-carotene) was most often recorded among persons engaged in bullet shooting (67%). The simultaneous lack of all three antioxidants was found only in freestylers and bobsledders (about 5%). Decreased level of antioxidants in blood serum in 40% of athletes was combined with vitamin B2 deficiency. The data obtained suggest the necessity to optimize diet vitamin content of all athletes, taking into account the age and gender differences. Contrary to prevailing stereotypes the optimization must involve not only an increase in the consumption of vitamins (vitamins E, B group) and carotenoids, but

From a clinical point of view, the prevalence of allergic contact dermatitis (ACD) among children and adolescents seems to be low. However, many children have dermatitis, most often atopic dermatitis. In selected cases, ACD is suspected, and the child is tested. The question remains, whether...... the prevalence of ACD in children really is low or whether the possibility of ACD is not sufficiently considered. During the last decade, reports have appeared on series of children and adolescents with contact allergy and ACD. Few cases have been reported in infants, but the development of contact allergy...... and ACD increases with age. Most studies include selected groups of children and adolescents with suspected ACD. Few studies have examined unselected populations, and most consider only the prevalence of contact allergy without evaluating the clinical relevance, e.g., the prevalence of ACD. Furthermore...

Conservatism in methodologies for moderator subcooling sufficiency for fuel channel integrity upon pressure tube and calandria tube contact

2015-07-01

During a postulated large LOCA event in CANDU reactors, the pressure tube may balloon to contact with its surrounding calandria tube to transfer heat to the moderator. To confirm the integrity of the fuel channel in this case, many experiments have been performed in the last three decades. Based on the extant database of the pressure tube/calandria tube (PT/CT) contact, an analytical methodology was developed by Canadian Nuclear Industry to determine the sufficiency of moderator subcooling for fuel channel integrity. At the same time a semi-empirical methodology with an idea of Equivalent Moderator Subcooling (EMS) was also developed to judge the sufficiency of the moderator. In this work, some discussions were made over the two methodologies on their conservatism and it is demonstrated that the analytical approach is over conservative comparing with the EMS methodology. By using the EMS methodology, it is demonstrated that applying glass-peened calandria tubes, the requirement to moderator subcooling can be reduced by 10{sup o}C from that for smooth calandria tubes.

Full Text Available Object: The aim of this study was to examine children driving to committing crime who were brought to psychiatry clinic for forensic evaluation because of the crimes they committed to. Additionally, evaluation of these children's psychiaytric disorders, crime characteristics, sociodemographic data, factors driving to committing crime and forensic reports arranged by the physician were other aims. Methods: In this study 204 children, who were brought to the clinic in order to be evaluated whether they perceive the legal meaning and consequences of that action or possess sufficient ability to channel their behaviors, were included. In order to diagnose any psychiatric disorder, a structured interrogation schedule for affective disorders and schizophrenia for present and lifetime was applied all children and families and sociodemographic data form was completed. Results: At least one psychiatric disorder was present in 47% (n =96 of children driving to committing crime. The most common disorders were Attention Deficit and Hyperactivity Disorder and Conduct Disorder. Almost none of them have been treated before. 45% of them dropped out their school, and 40% were smoking. Additionally, most of their parents who had low socioeconomical level also had very low education level. Discussion: It was determined that being male, living in a low socioeconomic family environment, living in large families, using drugs, smoking, not attending school and having parents with low education level were significant related factors for juvenile delinquency.

After the introduction of tubeless percutaneous nephrolithotomy (PNL), many studies conducted in adult patients have confirmed its efficacy and safety. There are limited studies reporting that tubeless PNL can be safely applied in children, however. Furthermore, there are no reports that evaluate the use of totally tubeless PNL in children. The present study evaluates the results of totally tubeless PNL in preschool children. The data of children seen in our clinic who were considered suitable for totally tubeless PNL were analyzed. Of 16 children, 8 patients underwent totally tubeless PNL (group 1) and 8 standard PNL (group 2). The two groups of patients were compared with regard to length of hospitalization, analgesic requirements, transfusion rates, hemoglobin (Hb) decrease, and immediate, early, and late complications. The mean ages of the patients were 56.6 months (9-84 mos) and 56.0 months (5-84 mos), and the mean follow-up was 21.5 months (3-44 mos) and 43.4 months (36-54 mos) in groups 1 and 2, respectively. Both groups were similar with regard to age, stone size, Hb change, and complications. Although operation duration, hospitalization period, and analgesic requirement were less in the totally tubeless PNL group, these differences were not statistically significant. The latest application of PNL, totally tubeless PNL, is also a safe and effective procedure in very small children if they are selected properly and if the surgeon has sufficient experience with the procedure. More studies with a higher number of participants are needed, however, to confirm that totally tubeless PNL increases the comfort of pediatric patients, decreases their hospitalization period, and is more economical.

Powerful Statistical Inference for Nested Data Using Sufficient Summary Statistics

Science.gov (United States)

Dowding, Irene; Haufe, Stefan

2018-01-01

Hierarchically-organized data arise naturally in many psychology and neuroscience studies. As the standard assumption of independent and identically distributed samples does not hold for such data, two important problems are to accurately estimate group-level effect sizes, and to obtain powerful statistical tests against group-level null hypotheses. A common approach is to summarize subject-level data by a single quantity per subject, which is often the mean or the difference between class means, and treat these as samples in a group-level t-test. This “naive” approach is, however, suboptimal in terms of statistical power, as it ignores information about the intra-subject variance. To address this issue, we review several approaches to deal with nested data, with a focus on methods that are easy to implement. With what we call the sufficient-summary-statistic approach, we highlight a computationally efficient technique that can improve statistical power by taking into account within-subject variances, and we provide step-by-step instructions on how to apply this approach to a number of frequently-used measures of effect size. The properties of the reviewed approaches and the potential benefits over a group-level t-test are quantitatively assessed on simulated data and demonstrated on EEG data from a simulated-driving experiment.

In order to analyze energy self-sufficient island, example of a smaller island, connected to the power system of a bigger island with an undersea cable, was taken. Mounting substation 10/0,4 is situated on the island and for the moment it provides enough electricity using the medium voltage line. It is assumed that the island is situated on the north part of the Adriatic Sea. The most important problem that occurs on the island is the population drop that occurs for a significant number of years, therefore, life standard needs to be improved, and economic development needs to be encouraged immediately. Local authorities to stimulate sustainable development on the island through different projects, to breath in a new life to the island, open new jobs and attract new people to come live there. Because of the planned development and increase of the population, energy projects, planned as a support to sustainable development, and later achievement of the energy self-sufficiency, is described in this paper. Therefore, Rewisland methodology appliance is described taking into the account three possible scenarios of energy development. Each scenario is calculated until year 2030. Also, what is taken into the account is 100% usage of renewable sources of energy in 2030. Scenario PTV, PP, EE - This scenario includes installation of solar photovoltaic modules and solar thermal collectors on the buildings roofs, as well as well as implementation of energy efficiency on the island (replacement of the street light bulbs with LED lightning, replacement of the old windows and doors on the houses, as well as the installation of the thermal insulation). Scenario PV island - This scenario, similarly to the previous one, includes installation of solar photovoltaic modules and solar thermal collectors an the residential buildings, as well as the 2 MW photovoltaic power plant and ''Green Hotel'', a building that satisfies all of its energy needs completely from renewable energy sources

The physical growth and cognitive development of elementary school children are very crucial and this group is large in number but has little research dedicated to it. The physical growth and cognitive development of children occur simultaneously and can be measured by body mass index (BMI) and intelligence quotient (IQ). Previous studies could not sufficiently focus on both aspects. The aim of this study was to identify determinants of BMI and IQ of students in two elementary schools in the Humla district of Nepal. Two randomly selected elementary schools and all children available there (n = 173) participated in the study. BMI was calculated with the objective of proper measurement of height and weight of the children. Likewise, the updated universal nonverbal intelligence test (UNIT) was applied for IQ. Descriptive statistics, t-test, analysis of variance and multiple linear regressions were used when appropriate. Study findings showed that one-tenth of the children had grade 2 thinness (-2SD) and about one-third had poor IQ (economic status (p Economic status and parent education are still major determinants of IQ and BMI in these students. Special programs and strategies should be launched to improve the poor ranking of IQ and BMI.

Activities, Participation and Quality of Life Concepts in Children and Adolescents with Celiac Disease: A Scoping Review

Full Text Available Celiac disease (CD is a food-related chronic condition and adherence to a strict gluten-free diet is the only available treatment. Adherence to the restrictive diet is challenging among children, especially adolescents. The aim was to describe existing knowledge about food-related activities, participation, and quality of life in daily life among children and adolescents with CD and to illuminate gaps in knowledge. The scoping review methodology was applied and literature searches were conducted in electronic databases. Twenty-three articles met the inclusion criteria. Food-related activities were identified, classified, and coded under the International Classification of Functioning, Disability, and Health adapted for children and youth (ICF-CY concepts of activities and participation. A wide variety of study populations, objectives, methods, and tools involving 55 different food-related activities were found. Incorporation of the ICF-CY concepts and quality of life captures new insights into everyday challenges. Reviewing the CD literature using this different lens reveals areas yet to receive sufficient attention. Further research can deepen the understanding of daily functioning of children with CD and the underlying skills required to participate in daily food-related activities while adhering to the diet. This can lead to the development of standardized disease-specific assessment tools and suitable intervention programs.

The influence of the TV and Videogames in Education of Children: Violence and Children

Full Text Available We have chosen this topic for research as we consider it a transcendental problem in the lives of children today, considering the importance which television now has toward childhood behavior and the increase of programming in new channels and the widespread use of videogames. Nowadays television hasn`t got sufficiently stipulated timetables; therefore children frequently watch violent scenes which are inappropriate for their age, with the added danger that they may want to imitate those scenes which cause the greatest impact in them and which can even cause them harm. We are including a recent research project (1999 on the influence of television and videogames in the conduct of children, as well as brief history of the principal authors who have studied this topic, the evolution of which has brought about notable changes and educational consequences.

Klatte, Stephanie; Wendisch, Volker F

2014-10-15

Whole cell biotransformation is an upcoming tool to replace common chemical routes for functionalization and modification of desired molecules. In the approach presented here the production of various non-natural (di)amines was realized using the designed whole cell biocatalyst Escherichia coli W3110/pTrc99A-ald-adh-ta with plasmid-borne overexpression of genes for an l-alanine dehydrogenase, an alcohol dehydrogenase and a transaminase. Cascading alcohol oxidation with l-alanine dependent transamination and l-alanine dehydrogenase allowed for redox self-sufficient conversion of alcohols to the corresponding amines. The supplementation of the corresponding (di)alcohol precursors as well as amino group donor l-alanine and ammonium chloride were sufficient for amination and redox cofactor recycling in a resting buffer system. The addition of the transaminase cofactor pyridoxal-phosphate and the alcohol dehydrogenase cofactor NAD(+) was not necessary to obtain complete conversion. Secondary and cyclic alcohols, for example, 2-hexanol and cyclohexanol were not aminated. However, efficient redox self-sufficient amination of aliphatic and aromatic (di)alcohols in vivo was achieved with 1-hexanol, 1,10-decanediol and benzylalcohol being aminated best.

Kepley, Hayden O; Ostrander, Rick

2007-02-01

To investigate the family environments of children in a community sample with ADHD and co-occurring anxiety. Family Environment Scale, Behavioral Assessment System for Children, and Structured Clinical Interview are administered to parents of children with ADHD with and without anxiety. ADHD families are uniformly less cohesive and expressive and possess more conflict than families representing the community sample. In contrast to community or nonanxious ADHD families, anxious ADHD families do not encourage independence and tend to be distinctly less assertive, self-sufficient, and autonomous. Although anxious and nonanxious ADHD children tend to have a uniformly high incidence of maternal ADHD, mothers of anxious ADHD children tend to display a much higher incidence of substance/alcohol abuse than either nonanxious or community participants. Findings are consistent with the notion that an insular, dependent, and somewhat controlling family environment characterizes families of children with ADHD and comorbid childhood anxiety.

CANDU: Meeting the demand for energy self-sufficiency

International Nuclear Information System (INIS)

Lawson, D.S.

1985-01-01

The success of the CANDU program can been seen quickly by examining the comparison of typical electricity bills in various provinces of Canada. The provinces of Quebec and Manitoba benefit b extensive hydro electric schemes, many of which were constructed years ago at low capital cost. In Ontario, the economic growth has outstripped these low cost sources of hydro power and hence the province has to rely on thermal sources of electricity generation. The success of the CANDU program is shown by the fact that it can contribute over a third of electricity in Ontario while keeping the total electricity rate comparable with that of those provinces that can rely on low cost hydro sources. Energy self-sufficiency encompasses a spectrum of requirements. One consideration would be the reliable supply and control of fuel during the operating life of a power plant: A greater degree of self-sufficiency would be obtained by having an involvement in the building and engineering of the power plant prior to its operation

Vaccine procurement and self-sufficiency in developing countries.

Woodle, D

2000-06-01

This paper discusses the movement toward self-sufficiency in vaccine supply in developing countries (and countries in transition to new economic and political systems) and explains special supply concerns about vaccine as a product class. It traces some history of donor support and programmes aimed at self-financing, then continues with a discussion about self-sufficiency in terms of institutional capacity building. A number of deficiencies commonly found in vaccine procurement and supply in low- and middle-income countries are characterized, and institutional strengthening with procurement technical assistance is described. The paper also provides information about a vaccine procurement manual being developed by the United States Agency for International Development (USAID) and the World Health Organization (WHO) for use in this environment. Two brief case studies are included to illustrate the spectrum of existing capabilities and different approaches to technical assistance aimed at developing or improving vaccine procurement capability. In conclusion, the paper discusses the special nature of vaccine and issues surrounding potential integration and decentralization of vaccine supply systems as part of health sector reform.

Information trimming: Sufficient statistics, mutual information, and predictability from effective channel states

Science.gov (United States)

James, Ryan G.; Mahoney, John R.; Crutchfield, James P.

2017-06-01

One of the most basic characterizations of the relationship between two random variables, X and Y , is the value of their mutual information. Unfortunately, calculating it analytically and estimating it empirically are often stymied by the extremely large dimension of the variables. One might hope to replace such a high-dimensional variable by a smaller one that preserves its relationship with the other. It is well known that either X (or Y ) can be replaced by its minimal sufficient statistic about Y (or X ) while preserving the mutual information. While intuitively reasonable, it is not obvious or straightforward that both variables can be replaced simultaneously. We demonstrate that this is in fact possible: the information X 's minimal sufficient statistic preserves about Y is exactly the information that Y 's minimal sufficient statistic preserves about X . We call this procedure information trimming. As an important corollary, we consider the case where one variable is a stochastic process' past and the other its future. In this case, the mutual information is the channel transmission rate between the channel's effective states. That is, the past-future mutual information (the excess entropy) is the amount of information about the future that can be predicted using the past. Translating our result about minimal sufficient statistics, this is equivalent to the mutual information between the forward- and reverse-time causal states of computational mechanics. We close by discussing multivariate extensions to this use of minimal sufficient statistics.

Visual impairment and traits of autism in children.

Science.gov (United States)

Wrzesińska, Magdalena; Kapias, Joanna; Nowakowska-Domagała, Katarzyna; Kocur, Józef

2017-04-30

Visual impairment present from birth or from an early childhood may lead to psychosocial and emotional disorders. 11-40% of children in the group with visual impairment show traits of autism. The aim of this paper was to present the selected examples of how visual impairment in children is related to the occurrence of autism and to describe the available tools for diagnosing autism in children with visual impairment. So far the relation between visual impairment in children and autism has not been sufficiently confirmed. Psychiatric and psychological diagnosis of children with visual impairment has some difficulties in differentiating between "blindism" and traits typical for autism resulting from a lack of standardized diagnostic tools used to diagnosing children with visual impairment. Another difficulty in diagnosing autism in children with visual impairment is the coexistence of other disabilities in case of most children with vision impairment. Additionally, apart from difficulties in diagnosing autistic disorders in children with eye dysfunctions there is also a question of what tools should be used in therapy and rehabilitation of patients.

The acquired preparedness risk model applied to smoking in 5th grade children.

Combs, Jessica L; Spillane, Nichea S; Caudill, Leann; Stark, Brittany; Smith, Gregory T

2012-03-01

The very early onset of smoking predicts numerous health problems. The authors conducted the first test of one risk model for elementary school age smoking, known as the acquired preparedness (AP) model of risk, in a cross-sectional sample of 309 5th grade children. The model posits that (a) impulsivity-related personality traits contribute to risk for a variety of risky, maladaptive behaviors; (b) smoking expectancies confer risk only for smoking; and (c) the personality traits contribute to the formation of high risk expectancies for reinforcement from smoking, which in turn increases the likelihood of early onset smoking. The model was supported: the high-risk personality traits distinguished children engaging in any risky, maladaptive behavior from other children, and the smoking expectancies differentiated smokers from all other children. The relationship between personality tendencies to act rashly when experiencing intense positive or negative emotions and smoker status was partially mediated by expectancies for reinforcement from smoking. This model should be investigated longitudinally. Copyright © 2011. Published by Elsevier Ltd.

FOOD SELF-SUFFICIENCY OF THE EUROPEAN UNION COUNTRIES – ENERGETIC APPROACH

Directory of Open Access Journals (Sweden)

Arkadiusz Sadowski

2016-06-01

Full Text Available The paper covers the issues of a basic social need, namely alimentation. The aim of the research is to evaluate the energetic food self-sufficiency and its changes in the European Union countries. The research has been conducted using the author’s methodology basing on the amount of energy produced and consumed in 1990-2009. The analyses proved that within the considered period, the European Union became an importer of net energy comprised in agricultural products. The excess in produced energy was mainly observed by the countries of European lowland. Moreover in most of the countries, a decrease in the analyzed factor was observed when compared with the 1990-1999 period. On the other hand, in relation to the new member states the increase in food energetic self-sufficiency was observed. The conclusion has been drawn that, while the general food self-sufficiency is mainly determined by environmental factors, its dynamics is primarily influenced by the factors connected with agricultural policy.

This paper reviews impacts on the nursing workforce of health policy and reforms of the past two decades and suggests reasons for both current difficulties in retaining nurses in the workforce and measures to achieve short-term improvements. Difficulties in retaining nurses in the New Zealand workforce have contributed to nursing shortages, leading to a dependence on overseas recruitment. In a context of global shortages and having to compete in a global nursing labour market, an alternative to dependence on overseas nurses is self-sufficiency. Discursive paper. Analysis of nursing workforce data highlighted threats to self-sufficiency, including age structure, high rates of emigration of New Zealand nurses with reliance on overseas nurses and an annual output of nurses that is insufficient to replace both expected retiring nurses and emigrating nurses. A review of recent policy and other documents indicates that two decades of health reform and lack of a strategic focus on nursing has contributed to shortages. Recent strategic approaches to the nursing workforce have included workforce stocktakes, integrated health workforce development and nursing workforce projections, with a single authority now responsible for planning, education, training and development for all health professions and sectors. Current health and nursing workforce development strategies offer wide-ranging and ambitious approaches. An alternative approach is advocated: based on workforce data analysis, pressing threats to self-sufficiency and measures available are identified to achieve, in the short term, the maximum impact on retaining nurses. A human resources in health approach is recommended that focuses on employment conditions and professional nursing as well as recruitment and retention strategies. Nursing is identified as 'crucial' to meeting demands for health care. A shortage of nurses threatens delivery of health services and supports the case for self-sufficiency in the nursing

Self-sufficient decentralized systems challenge the centralized energy paradigm. Although scholars have assessed specific locations and technological aspects, it remains unclear how, when, and where energy self-sufficiency could become competitive. To address this gap, we develop a techno-economic model for energy self-sufficient neighborhoods that integrates solar photovoltaics (PV), conversion, and storage technologies. We assess the cost of 100% self-sufficiency for both electricity and heat, comparing different technical configurations for a stylized neighborhood in Switzerland and juxtaposing these findings with projections on market and technology development. We then broaden the scope and vary the neighborhood's composition (residential share) and geographic position (along different latitudes). Regarding how to design self-sufficient neighborhoods, we find two promising technical configurations. The "PV-battery-hydrogen" configuration is projected to outperform a fossil-fueled and grid-connected reference configuration when energy prices increase by 2.5% annually and cost reductions in hydrogen-related technologies by a factor of 2 are achieved. The "PV-battery" configuration would allow achieving parity with the reference configuration sooner, at 21% cost reduction. Additionally, more cost-efficient deployment is found in neighborhoods where the end-use is small commercial or mixed and in regions where seasonal fluctuations are low and thus allow for reducing storage requirements.

India's baseline plan for nuclear energy self-sufficiency

International Nuclear Information System (INIS)

Bucher, R.G.

2009-01-01

United Nations Conference on the Peaceful Uses of Atomic Energy in 1958. The paper described a three stage plan for a sustainable nuclear energy program consistent with India's limited uranium but abundant thorium natural resources. In the first stage, natural uranium would be used to fuel graphite or heavy water moderated reactors. Plutonium extracted from the spent fuel of these thermal reactors would drive fast reactors in the second stage that would contain thorium blankets for breeding uranium-233 (U-233). In the final stage, this U-233 would fuel thorium burning reactors that would breed and fission U-233 in situ. This three stage blueprint still reigns as the core of India's civil nuclear power program. India's progress in the development of nuclear power, however, has been impacted by its isolation from the international nuclear community for its development of nuclear weapons and consequent refusal to sign the Nuclear Nonproliferation Treaty (NPT). Initially, India was engaged in numerous cooperative research programs with foreign countries; for example, under the 'Atoms for Peace' program, India acquired the Cirus reactor, a 40 MWt research reactor from Canada moderated with heavy water from the United States. India was also actively engaged in negotiations for the NPT. But, on May 18, 1974, India conducted a 'peaceful nuclear explosion' at Pokharan using plutonium produced by the Cirus reactor, abruptly ending the era of international collaboration. India then refused to sign the NPT, which it viewed as discriminatory since it would be required to join as a non-nuclear weapons state. As a result of India's actions, the Nuclear Suppliers Group (NSG) was created in 1975 to establish guidelines 'to apply to nuclear transfers for peaceful purposes to help ensure that such transfers would not be diverted to unsafeguarded nuclear fuel cycle or nuclear explosive activities. These nuclear export controls have forced India to be largely self-sufficient in all nuclear

Entrepreneurship by any other name: self-sufficiency versus innovation.

Science.gov (United States)

Parker Harris, Sarah; Caldwell, Kate; Renko, Maija

2014-01-01

Entrepreneurship has been promoted as an innovative strategy to address the employment of people with disabilities. Research has predominantly focused on the self-sufficiency aspect without fully integrating entrepreneurship literature in the areas of theory, systems change, and demonstration projects. Subsequently there are gaps in services, policies, and research in this field that, in turn, have limited our understanding of the support needs and barriers or facilitators of entrepreneurs with disabilities. A thorough analysis of the literature in these areas led to the development of two core concepts that need to be addressed in integrating entrepreneurship into disability employment research and policy: clarity in operational definitions and better disability statistics and outcome measures. This article interrogates existing research and policy efforts in this regard to argue for a necessary shift in the field from focusing on entrepreneurship as self-sufficiency to understanding entrepreneurship as innovation.

Haga, M

2008-05-01

This study examined the relationship between physical fitness and motor competence in children aged 9-10 years. A sample of 67 children (mean age 9.7, SD 0.3 year) participated in the study. To assess motor competence, each child completed the Movement Assessment Battery for Children. Physical fitness was measured by the Test of Physical Fitness, comprising nine different tasks including running, jumping, throwing and climbing. The results show a strong and significant correlation between motor competence and physical fitness within the sample. These results are relevant to the work of maintaining and developing both sufficient physical fitness and motor competence in children as these factors are important contributors to their health and well-being.

Children's and parents' perceptions of care during the peri-radiographic process when the child is seen for a suspected fracture

International Nuclear Information System (INIS)

Björkman, B.; Enskär, K.; Nilsson, S.

2016-01-01

Background: Visiting a Radiology department may elicit both positive and negative feelings for children and parents alike. This study investigated children's and parents' perceptions of care during the peri-radiographic process and whether these perceptions correlated with the child's perceptions of pain and distress. Methods: This study utilized a quantitative descriptive design. Its data was collected in five Radiology departments, two where examinations are performed exclusively on children and three that treat both children and adults. Data collection contained questionnaires from children (n = 110) and their parent (n = 110) as well as children's self-reports of pain and distress. Results: The findings illustrated that the children and their parent were satisfied with the care provided throughout the peri-radiographic process, unrelated to the child's self-reported levels of pain and distress or examination setting (i.e. children's department or general department). The highest scores of satisfaction were ascribed to “the radiographer's kindness and ability to help in a sufficient way,” whereas “available time to ask questions and to meet the child's emotional needs” received the lowest scores. Conclusions: Parents and children alike perceived the radiographers as skilled and sensitive throughout the examination, while radiographers' time allocated to interacting with the child was not perceived be sufficiently covered. - Highlights: • Children seen for an acute radiographic examination were satisfied with the provided care. • The radiographers were perceived as both skilled and sensitive to the children's needs. • Children experienced pain and distress during examination on levels ranging from mild to severe. • The allocated time for the children to ask questions were not sufficiently covered. • It is suggested that routines be implemented to reduce children's pain and distress

2014-01-01

Full Text Available Background. This study aimed to compare the effects of rectal midazolam addition after applying bupivacaine and caudal anesthesia on postoperative analgesia time, the need for additional analgesics, postoperative recovery, and sedation and to find out its adverse effects in children having lower abdominal surgery. Methods. 40 children between 2 and 10 years of ASA I-II were randomized, and they received caudal anesthesia under general anesthesia. Patients underwent the application of caudal block in addition to saline and 1 mL/kg bupivacaine 0.25%. In the postoperative period, Group C (n = 20 was given 5 mL saline, and Group M (n = 20 was given 0.30 mg/kg rectal midazolam diluted with 5 mL saline. Sedation scale and postoperative pain scale (CHIPPS of the patients were evaluated. The patients were observed for their analgesic need, first analgesic time, and adverse effects for 24 hours. Results. Demographic and hemodynamic data of the two groups did not differ. Postoperative sedation scores in both groups were significantly lower compared with the preoperative period. There was no significant difference between the groups in terms of sedation and sufficient analgesia. Conclusions. We conclude that caudal anesthesia provided sufficient analgesia in peroperative and postoperative periods, and rectal midazolam addition did not create any differences. This trial is registered with ClinicalTrials.gov NCT02127489.

Effect of hearing loss on semantic access by auditory and audiovisual speech in children.

Science.gov (United States)

Jerger, Susan; Tye-Murray, Nancy; Damian, Markus F; Abdi, Hervé

2013-01-01

This research studied whether the mode of input (auditory versus audiovisual) influenced semantic access by speech in children with sensorineural hearing impairment (HI). Participants, 31 children with HI and 62 children with normal hearing (NH), were tested with the authors' new multimodal picture word task. Children were instructed to name pictures displayed on a monitor and ignore auditory or audiovisual speech distractors. The semantic content of the distractors was varied to be related versus unrelated to the pictures (e.g., picture distractor of dog-bear versus dog-cheese, respectively). In children with NH, picture-naming times were slower in the presence of semantically related distractors. This slowing, called semantic interference, is attributed to the meaning-related picture-distractor entries competing for selection and control of the response (the lexical selection by competition hypothesis). Recently, a modification of the lexical selection by competition hypothesis, called the competition threshold (CT) hypothesis, proposed that (1) the competition between the picture-distractor entries is determined by a threshold, and (2) distractors with experimentally reduced fidelity cannot reach the CT. Thus, semantically related distractors with reduced fidelity do not produce the normal interference effect, but instead no effect or semantic facilitation (faster picture naming times for semantically related versus unrelated distractors). Facilitation occurs because the activation level of the semantically related distractor with reduced fidelity (1) is not sufficient to exceed the CT and produce interference but (2) is sufficient to activate its concept, which then strengthens the activation of the picture and facilitates naming. This research investigated whether the proposals of the CT hypothesis generalize to the auditory domain, to the natural degradation of speech due to HI, and to participants who are children. Our multimodal picture word task allowed us

The aim of the study is to determinate the using dominant multiple intelligence types and compare the learning preferences of Turkish cochlear implanted children aged four to ten in Turkey and Germany according to Theory of multiple intelligence. The study has been conducted on a total of 80 children and four groups in Freiburg/Germany and Ankara/Turkey. The applications have been done in University of Freiburg, Cochlear Implant Center in Germany, and University of Hacettepe, ENT Department, Audiology and Speech Pathology Section in Turkey. In this study, the data have been collected by means of General Information Form and Cochlear Implant Information Form applied to parents. To determine the dominant multiple intelligence types of children, the TIMI (Teele Inventory of Multiple Intelligences) which was developed by Sue Teele have been used. The study results exposed that there was not a statistically significant difference on dominant intelligence areas and averages of scores of multiple intelligence types in control groups (p>0.05). Although, the dominant intelligence areas were different (except for first dominant intelligence) in cochlear implanted children in Turkey and Germany, there was not a statistically significant difference on averages of scores of dominant multiple intelligence types. Every hearing impaired child who started training, should be evaluated in terms of multiple intelligence areas and identified strengths and weaknesses. Multiple intelligence activities should be used in their educational programs. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

Refueling availability for alternative fuel vehicle markets: Sufficient urban station coverage

International Nuclear Information System (INIS)

Melaina, Marc; Bremson, Joel

2008-01-01

Alternative fuel vehicles can play an important role in addressing the challenges of climate change, energy security, urban air pollution and the continued growth in demand for transportation services. The successful commercialization of alternative fuels for vehicles is contingent upon a number of factors, including vehicle cost and performance. Among fuel infrastructure issues, adequate refueling availability is one of the most fundamental to successful commercialization. A commonly cited source reports 164,300 refueling stations in operation nationwide. However, from the perspective of refueling availability, this nationwide count tends to overstate the number of stations required to support the widespread deployment of alternative fuel vehicles. In terms of spatial distribution, the existing gasoline station networks in many urban areas are more than sufficient. We characterize a sufficient level of urban coverage based upon a subset of cities served by relatively low-density station networks, and estimate that some 51,000 urban stations would be required to provide this sufficient level of coverage to all major urban areas, 33 percent less than our estimate of total urban stations. This improved characterization will be useful for engineering, economic and policy analyses. (author)

Determine the prevalence of fat-soluble vitamin deficiency in children with cystic fibrosis (CF) aged ≤18 years in New South Wales (NSW), Australia, from 2007 to 2010. A retrospective analysis of fat-soluble vitamin levels in children aged ≤18 years who lived in NSW and attended any of the three paediatric CF centres from 2007 to 2010. An audit of demographic and clinical data during the first vitamin level measurement of the study period was performed. Deficiency of one or more fat-soluble vitamins was present in 240/530 children (45%) on their first vitamin level test in the study period. The prevalence of vitamins D and E deficiency fell from 22.11% in 2007 to 15.54% in 2010, and 20.22% to 13.89%, respectively. The prevalence of vitamin A deficiency increased from 11.17% to 13.13%. Low vitamin K was present in 29% in 2007, and prevalence of prolonged prothrombin time increased from 19.21% to 22.62%. Fat-soluble vitamin deficiency is present in 10%-35% of children with pancreatic insufficiency, but only a very small proportion of children who are pancreatic-sufficient. This is one of few studies of fat-soluble vitamin deficiency in children with CF in Australia. Fat-soluble vitamin testing is essential to identify deficiency in pancreatic-insufficient children who may be non-compliant to supplementation or require a higher supplement dose, and pancreatic-sufficient children who may be progressing to insufficiency. Testing of vitamin K-dependent factors needs consideration. Further studies are needed to monitor rates of vitamin deficiency in the CF community. Published by the BMJ Publishing Group Limited.

2014-08-01

Full Text Available Cultivation of the strategic crop of rice highly depends to the existence of sufficient and guaranteed irrigation water, and water shortage stresses have irreparable effects on yield and quality of productions. Decrease of the Sefidrud river inflow in Guilan province which is the main source of supplying irrigation water for 171 thousand hectares under rice cropping area of this province, has been challenged sufficient and guaranteed irrigation water supply in many regions of mentioned province. Hence, in present study estimating the value that paddy farmers place on sufficient and guaranteed irrigation water supply has been considered. Economic valuation of sufficient and guaranteed irrigation water supply improves water resource management policies in demand side. Requested data set were obtained on the base of a survey and are collected from 224 paddy farms in rural regions that faced with irrigation water shortages. Then, using open-ended valuation approach and estimation of Tobit model via ML and two stages Heckman approach, eliciting paddy farmers' willingness to pay for sufficient and guaranteed irrigation water supply has been accomplished. Results revealed that farmers in investigated regions willing to pay 26.49 percent more than present costs of providing irrigation water in order to have sufficient and guaranteed irrigation water.

Sufficient education attainment for a decent standard of living in modern Australia

Directory of Open Access Journals (Sweden)

Emily Joy Callander

2012-06-01

Full Text Available Education attainment will impact upon an individual’s capacity to engage in the labour force, their living standards and hence their poverty status. As such, education should be included in measures of poverty. However, it is not known what a sufficient level of education to have a decent standard of living is. Using the 2003 Survey of Disability, Ageing and Carers different levels of education attainment were tested for their association with labour force participation and income. Based upon this, it was concluded that Year 12 or higher is a sufficient level of education attainment for 15 to 64 year olds; and Year 10 or higher for people over the age of 65 years. This is in line with current government policies to improve Year 12 completion rates. Knowing what a ‘sufficient level of education attainment’ is, allows education to be included in multidimensional measures of poverty that view education as a key dimension of disadvantage.

Very mild fluorosis is quite prevalent in children and one of the sources may be attributed to poor fluoride toothpaste utilization habits. To investigate the frequency of toothbrushing, parental supervision, the person who usually applied the toothpaste, toothpaste swallowing and spitting habits, size of toothbrush, type of toothpaste used and amount of toothpaste used by shape and weight. Observational cross-sectional study of a representative random sample of 373 children aged 5-6 year-old. The children were interviewed using a structured close ended questionnaire. Direct observations were made on their toothpaste dispensing habit during a toothbrushing exercise. All children reported practising toothbrushing with 90% on a daily basis. Almost all used fluoridated toothpaste (91.4%). About one-half (50.7%) reported that their parents never supervised them. More than one-third of children used adult toothpaste and 60.1% of the toothpaste was flavoured. Most (92%) used toothbrush meant for children. About 40% applied a pea-sized amount of toothpaste. The mean weight of toothpaste applied was 0.43 g (SID + 0.35 g). The majority used the recommended child-sized toothbrush and toothpaste that contained fluoride but less than one-half of the parents supervised their children. Most children used flavoured children's toothpaste but a sizable proportion used toothpastes meant for adults. The amount applied by shape and weight exceeded the amount recommended by experts.

Probiotics in antibiotic associated diarrhea in children

Directory of Open Access Journals (Sweden)

Matjaž Homan

2013-10-01

Full Text Available The use of antibiotics that disturb the gastrointestinal microbiota is associated with diarrhea, which occurs in up to half of treated children. Symptoms are usually mild and children do not need hospitalization. Probiotics are live microorganisms, which restore intestinal microbiota during antibiotic therapy through different mechanisms such as stimulation of immunity, secretion of anti-inflammatory factors, and production of antimicrobial substances. The use of different strains of probiotics in antibiotic-associated diarrhea was evaluated in several studies in adults but less frequently in pediatric population. They also confirmed the value of probiotics in the prevention of antibiotic-associated diarrhea in children, particularly Lactobacillus strain GG and Saccharomyces boulardii. The use of probiotics in childhood is safe. A proper strain must be introduced at the beginning of antibiotic treatment in a sufficient concentration.

Thyroid volumes and urinary iodine in German school children.

Rendl, J; Juhran, N; Reiners, C

2001-01-01

Several recently published investigations showed a significant improvement in the iodine supply of the German population, but so far Germany is still considered an iodine deficient country. However most of the studies presented do not meet the epidemiological criteria established by WHO, UNICEF and ICCIDD and may therefore suffer from a selection bias with respect to goiter prevalence estimates. School children, owing to their easy recruitment, representativeness of different socio-economic classes and high vulnerability of Iodine deficiency disorders (IDD), are one of the best target groups for surveillance of IDD. In this field study a total of 591 children were investigated. The total sample included 268 females and 323 males aged 7-17 years. The following data were collected: thyroid size by ultrasound, urinary iodine concentration in a first-morning spot urine, weight, height, sex and age. The median urinary iodine concentration of the children was 183 microg/L. The proportion of samples with concentrations below 100 microg/L or below 50 microg/L was 15.4% and 4.3% respectively. Urine samples with high iodine concentrations were also found amounting to 17.3%. Almost all families (97%) declared to use iodized kitchen salt and 19.6% of all children are taking regularly iodine tablets. Application of the WHO/ICCIDD thyroid volume references to the German children resulted in a goiter prevalence of 0.2%, using either age/sex-specific or body surface area (BSA)/sex-specific cut-off values. Comparison with the P97 values of the original normative data of Gutekunst and Martin-Teichert however gives a goiter prevalence of 3% as expected. The thyroid volumes of the children in our study appear comparable with those reported recently for iodine sufficient children from Switzerland and for iodine replete Berlin children and for children with sufficient iodine supply in the region of Leipzig, so that Germany probably has no longer to be considered an iodine deficient

Torture in children.

Science.gov (United States)

Quiroga, Jose

2009-01-01

This is a review article that studies the problem of torture in children. Torture in children is a significant worldwide problem, but there are no official or reliable independent statistics to measure the magnitude of the problem. The definition of torture in the Convention against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment applies to adults and children. The Convention on the Rights of the Child defines children as "every human being below the age of eighteen years". Torture in children happens during peace times and during political violence and war conflicts. The majority of torture victims happen during peace times. The high-risk groups are impoverished children living in the street, children deprived of parental care, children in conflict with the law, and children in detention. During political violence and war the high risk children are the children detained during political violence, child soldiers, children internally displaced in refugee camps, detained children during the war against terrorism and children tortured by peacekeeping forces. The perpetrators of torture in children are the members of the same forces that torture adults, generally the police, civil police, security guards trained by police, prison guards, and military forces. The paper identifies some preventive measure and develops recommendations for action at the local, national and international level.

Ideal energy self-sufficient bioclimatic house

1990-04-01

This paper points out some of the interesting architectural features of a conceptual house being designed to be self-sufficient relative to the use of conventional energy sources. Brief notes are given on the following special design characteristics: the house's orientation and form - essentially a V - shaped two storey design with an orientation such as to maximize the surface area exposed to winter insolation; its special low emissivity glazing equipped with nightfall insulating screens; the adoption of maximized insulation, in which case cost benefits were assessed based on amortization over the entire life span of the house; hybrid space heating and ventilation systems involving the integration of pumps and ventilators for air circulation, and the use of a varied mix of active and passive solar heating and cooling systems.

Conclusions: The results support the effectiveness of the parent involvement intervention in promoting child-parent relationship and dietary self-efficacy of children. However, a 5-week parent involvement intervention was not sufficient to produce significant changes in children's body mass index. Further research is needed to investigate effects of parent involvement intervention with long-term evaluation.

Micronutrients in the life cycle: Requirements and sufficient supply

Directory of Open Access Journals (Sweden)

K. Biesalski Hans

2018-06-01

Full Text Available Macronutrients (fat, protein, carbohydrates deliver energy and important material to ensure the entire body composition. Micronutrients are needed to keep this process of continuous construction and re-construction running. Consequently, the requirement for micronutrients will differ depending on the individual need which is related to the different metabolic conditions within the life cycle. Within the first 1000 days of life, from conception to the end of the second year of life the requirement for micronutrients is high and if the supply is inadequate that might have consequences for physical and at least cognitive development. In particular, iron, iodine, vitamin D and folate are micronutrients which might become critical during that period. Due to the fact that clinical symptoms of deficiencies develop late, but inadequate supply of one or more micronutrients may have consequences for health the term hidden hunger has been introduced to describe that situation. In particular the time period of pregnancy and early childhood is critical and hidden hunger is a worldwide problem, affecting >2 billion people, primarily females and children. The importance of different requirements during the life cycle is usually not considered. In addition, we do not really know what the individual requirement is. The estimation of the requirement is based on studies calculating the supply of a micronutrient to avoid a deficiency disease within a healthy population and is not based on sound scientific methodology or data. We need to consider that at different moments in the life cycle the supply might become critical in particular in case of a disease or sudden increase of metabolic turnover. In this narrative review we summarize data from studies dealing with different micronutrient requirements in pregnancy, exercise, vegan diet, adolescents and elderly. Knowledge of critical periods and related critical micronutrients might help to avoid hidden hunger and

Temperament moderates the association between sleep duration and cognitive performance in children

Radiation exposure in nucleomedical examinations of children

International Nuclear Information System (INIS)

Hahn, K.; Hach, A.; Reber, H.

1995-01-01

The problem of radiation exposure must be subjected to particularly careful scrutiny in nuclear diagnostic procedures in children. The contribution provides a survey of factors influencing the radiation exposure of children in the diagnostic use of radionuclides. These include the age of the child examined, the type of radiopharmaceutical used, the dose of the radiopharmaceutical and the procedure followed. Any state-of-the-art renal function study or skeletal examination using radionuclides requires previous measures to ensure that the child is sufficiently hydrated. The tables in the appendix provide estimations of the doses from the individual nucleomedical procedures used in paediatrics. (orig./MG) [de

Highlights: •Various influencing factors of energy use in WWTPs are characterized. •Benchmark energy consumption in WWTPs in different countries are highlighted. •Energy recovery or saving technologies in WWTPs are summarized. •Recent advances in optimization of energy recovery technologies are highlighted. •Feasibility and challenges of energy self-sufficient WWTPs are explored. -- Abstract: Energy efficiency optimization is crucial for wastewater treatment plants (WWTPs) because of increasing energy costs and concerns about global climate change. Energy efficiency optimization can be achieved through a combination of energy recovery from the wastewater treatment process and energy saving-related technologies. Through these two approaches energy self-sufficiency of WWTPs is achievable, and research is underway to reduce operation costs and energy consumption and to achieve carbon neutrality. In this paper, we analyze energy consumption and recovery in WWTPs and characterize the factors that influence energy use in WWTPs, including treatment techniques, treatment capacities, and regional differences. Recent advances in the optimization of energy recovery technologies and theoretical analysis models for the analysis of different technological solutions are presented. Despite some challenges in implementation, such as technological barriers and high investment costs, particularly in developing countries, this paper highlights the potential for more energy self-sufficient WWTPs to be established in the future.

Lambek, Rikke; Tannock, Rosemary; Dalsgaard, Søren

2011-01-01

Objective: The study examined executive function deficits (EFD) in school-age children (7 to 14 years) with ADHD. Method: A clinical sample of children diagnosed with ADHD (n = 49) was compared to a population sample (n = 196) on eight executive function (EF) measures. Then, the prevalence of EFD...... in clinical and non-clinical children was examined at the individual level according to three methods previously applied to define EFD, and a fourth method was included to control for the effect of age on performance. Results: Children with ADHD were significantly more impaired on measures of EF than children...... without ADHD at the group level. However, only about 50% of children with ADHD were found to have EFD at the individual level, and results appeared relatively robust across methods applied to define EFD. Conclusion: As a group, children with ADHD displayed more problems on neuropsychological measures...

Andrews, Cheryl; O'Brian, Sue; Onslow, Mark; Packman, Ann; Menzies, Ross; Lowe, Robyn

2016-06-01

A recent clinical trial (Andrews et al., 2012) showed Syllable Timed Speech (STS) to be a potentially useful treatment agent for the reduction of stuttering for school-age children. The present trial investigated a modified version of this program that incorporated parent verbal contingencies. Participants were 22 stuttering children aged 6-11 years. Treatment involved training the children and their parents to use STS in conversation. Parents were also taught to use verbal contingencies in response to their child's stuttered and stutter-free speech and to praise their child's use of STS. Outcome assessments were conducted pre-treatment, at the completion of Stage 1 of the program and 6 months and 12 months after Stage 1 completion. Outcomes are reported for the 19 children who completed Stage 1 of the program. The group mean percent stuttering reduction was 77% from pre-treatment to 12 months post-treatment, and 82% with the two least responsive participants removed. There was considerable variation in response to the treatment. Eleven of the children showed reduced avoidance of speaking situations and 18 were more satisfied with their fluency post-treatment. However, there was some suggestion that stuttering control was not sufficient to fully eliminate situation avoidance for the children. The results of this trial are sufficiently encouraging to warrant further clinical trials of the method. Copyright © 2016 Elsevier Inc. All rights reserved.

Highlights: • Secondary exploratory analyses displayed a correlation of blood Pb to HBsAb levels. • Generalized linear mixed models were used to analyze two-phase data. • Children from an e-waste area had higher blood Pb levels and lower HBsAb titers. • Nearly 50% of Pb-exposed children fail to develop sufficient HBV immunity. • Different vaccination strategies are required for in e-waste areas. - Abstract: Lead (Pb) is a widespread environmental contaminant that can profoundly affect the immune system in vaccinated children. To explore the association between blood Pb and HBsAb levels in children chronically exposed to Pb, we measured hepatitis B surface antibody (HBsAb) titers, to reflect the immune response in the children of Guiyu, an electronic and electrical waste (e-waste) recycling area well known for environmental Pb contamination. We performed secondary exploratory analyses of blood Pb levels and plasma HBsAb titers in samples, taken in two phases between 2011 and 2012, from 590 children from Guiyu (exposed group) and Haojiang (reference group). Children living in the exposed area had higher blood Pb levels and lower HBsAb titers compared with children from the reference area. At each phase, generalized linear mixed models (GLMMs) showed that HBsAb titers were significantly negatively associated with child blood Pb levels. This work shows that a decreased immune response to hepatitis B vaccine and immune system might have potential harm to children with chronic Pb exposure. Importantly, nearly 50% of chronically exposed children failed to develop sufficient immunity to hepatitis in response to vaccination. Thus different vaccination strategies are needed for children living under conditions of chronic Pb exposure.

Dundon Belinda

2009-07-01

Full Text Available Abstract Background Nausea and vomiting is a problem for children after neurosurgery and those requiring posterior fossa procedures appear to have a high incidence. This clinical observation has not been quantified nor have risk factors unique to this group of children been elucidated. Methods A six year retrospective chart audit at two Canadian children's hospitals was conducted. The incidence of nausea and vomiting was extracted. Hierarchical multivariable logistic regression was used to quantify risk and protective factors at 120 hours after surgery and early vs. late vomiting. Results The incidence of vomiting over a ten day postoperative period was 76.7%. Documented vomiting ranged from single events to greater than 20 over the same period. In the final multivariable model: adolescents (age 12 to Conclusion The incidence of vomiting in children after posterior fossa surgery is sufficient to consider all children requiring these procedures to be at high risk for POV. Nausea requires better assessment and documentation.

Is high dose methotrexate without irradiation of the brain sufficiently effective in prevention of CNS disease in children with acute lymphoblastic leukemia?

International Nuclear Information System (INIS)

Cap, J.; Foltinova, A.; Kaiserova, E.; Mojzesova, A.; Sejnova, D.; Jamarik, M.

1998-01-01

We present 5-year results of treatment in 93 children suffering from acute lymphoblastic leukemia using two therapeutic protocols containing multidrug chemotherapy including high dose methotrexate. We could ascertain different results in standard and high risk patients. In a group of 62 children with standard risk we observed improvement in complete remission rate being 98.9% after induction phase of therapy, only one patient died on septicemia. Relapse rate in this group was 21.2% and that 14. 7% in the bone marrow and 6.5% in CNS and no testicular relapse at all. In the group of 31 children with high risk leukemia all patients achieved complete remission. Only one of them died on acute pancreatitis due to toxicity. Overall relapse rate in this group was 28.9% with 12.8% of medullary relapse and 16.1 % of CNS relapse. The last one was significantly higher than in the previous study when brain irradiation was a part of therapeutic procedure. It seems that this treatment is effective mainly in the standard risk leukemia, however, in the high risk leukemias this procedure appears to be less effective in preventing CNS leukemia. In this group of patients irradiation of the brain need to be enclosed in the therapy. (authors)

Noise levels from toys and recreational articles for children and teenagers.

Hellstrom, P A; Dengerink, H A; Axelsson, A

1992-10-01

This study examined the noise level emitted by toys and recreational articles used by children and teenagers. The results indicate that many of the items tested emit sufficiently intense noise to be a source of noise induced hearing loss in school-age children. While the baby toys provided noise exposure within the limits of national regulations, they are most intense in a frequency range that corresponds to the resonance frequency of the external auditory canal of very young children. Hobby motors emit noise that may require protection depending upon the length of use. Fire-crackers and cap guns emit impulse noises that exceed even conservative standards for noise exposure.

Lead–acid batteries coupled with photovoltaics for increased electricity self-sufficiency in households

Oliveira e Silva de, Guilherme; Hendrick, Patrick

2016-01-01

Highlights: • Grid parity is reached for PV installations up to nearly 40% self-sufficiency. • Reaching beyond 40% self-sufficiency requires storage and support policies. • Peak consumption remains constant but load variability rises with self-sufficiency. • Changes in power plants portfolio and wholesale electricity prices are expected. • Limiting feed-in power is a promising solution for reducing load variability. - Abstract: With distributed generation of electricity growing in importance (especially with photovoltaics) and buildings being one of the main consumers of energy in modern societies, distributed storage of energy in buildings is expected to become increasingly present. This paper analyses the use of residential lead–acid energy storage coupled with photovoltaics and its possible interaction with the grid for different limits of feed-in power without any support policies. In the literature, these subjects are often treated independently and for very specific, non-optimised cases, thus motivating further research. Results show that reaching self-sufficiency values up to 40% is possible, close to grid parity values, and only with photovoltaics. Beyond 40%, energy storage must be used, strongly raising the cost of the electricity consumed and therefore the need for support policies for widespread adoption. Also, peak power consumption from the grid remains constant and load variability rises, suggesting that an increase in self-sufficiency would be accompanied by lower utilisation factors of power plants and, consequently, higher wholesale electricity prices during no sunshine hours. Limiting feed-in power attenuates the increased load variability and only slightly affects the economic viability of such installations. These results present a novel optimisation tool for developers and should be considered in future studies of distributed photovoltaics and energy storage as well as in energy policy.

Increased vitamin D intake differentiated according to skin color is needed to meet requirements in young Swedish children during winter: a double-blind randomized clinical trial.

Öhlund, Inger; Lind, Torbjörn; Hernell, Olle; Silfverdal, Sven-Arne; Karlsland Åkeson, Pia

2017-07-01

Background: Dark skin and low exposure to sunlight increase the risk of vitamin D insufficiency in children. Objective: The aim of the study was to evaluate the amount of vitamin D needed to ascertain that most children >4 y of age attain sufficient serum 25-hydroxyvitamin D [S-25(OH)D; i.e., ≥50 nmol/L] during winter regardless of latitude and skin color. Design: In a longitudinal, double-blind, randomized, food-based intervention study, 5- to 7-y-old children from northern (63°N) and southern (55°N) Sweden with fair ( n = 108) and dark ( n = 98) skin were included. Children, stratified by skin color by using Fitzpatrick's definition, were randomly assigned to receive milk-based vitamin D 3 supplements that provided 2 (placebo), 10, or 25 μg/d during 3 winter months. Results: Mean daily vitamin D intake increased from 6 to 17 μg and 26 μg in the intervention groups supplemented with 10 and 25 μg, respectively. In the intention-to-treat analysis, 90.2% (95% CI: 81.1%, 99.3%) of fair-skinned children randomly assigned to supplementation of 10 μg/d attained sufficient concentrations, whereas 25 μg/d was needed in dark-skinned children to reach sufficiency in 95.1% (95% CI: 88.5%, 100%). In children adherent to the study product, 97% (95% CI: 91.3%, 100%) and 87.9% (95% CI: 76.8%, 99%) of fair- and dark-skinned children, respectively, achieved sufficient concentrations if supplemented with 10 μg/d. By using 95% prediction intervals for 30 and 50 nmol S-25(OH)D/L, intakes of 6 and 20 μg/d are required in fair-skinned children, whereas 14 and 28 μg/d are required in children with dark skin. Conclusion: Children with fair and dark skin require vitamin D intakes of 20 and 28 μg/d, respectively, to maintain S-25(OH)D ≥50 nmol/L, whereas intakes of 6 and 14 μg/d, respectively, are required to maintain concentrations ≥30 nmol/L during winter.

Weber, Annhild; Karle, Michael; Klosinski, Gunther

2004-03-01

On the basis of 45 expert opinions of custody cases involving 89 children dating from 1996-1999 and of 62 questionnaires answered by the parents it was examined, how the parents told their children about the impending separation. We were interested if the way the parents told their children and the contents of the communication had an impact on coping with the separation. We found that only 48.9% of the families talked about the separation. 35.5% of the children were not informed, 12.4% of the children were not told the truth by their parents. There was no clear connection between the way the children were informed and their coping behaviour. Yet it could be shown that talking to the children had a positive effect on the relationship between the father and the child. The discussion of the results will point out the complexity and importance of this topic which has not been sufficiently considered in the literature and by parents planning a divorce. Yet looking at the rising divorce rate one can see how highly topical it is and will remain in the future.

Elderly people are becoming more prevalent in our country, which studies in this group are relevant. Moreover, the health impact of breakfast consumption is demonstrated in school groups. To determine whether breakfast consumption is associated with better quality of life in self-sufficient Chilean elderly. We interviewed 1,285 elderly (> 60 years) of both sexes. We applied two surveys (food and healthy lifestyles surveys), then an anthropometric evaluation was conducted. 5.6% of older adults does not consume breakfast. Those who consume breakfast had a better quality of life (p = 0.004), specifically in men breakfast intake is associated with lower body mass index (BMI) (p=0.002). Moreover, the results indicate that the proportion of elderly who smokes and does not take breakfast is higher, as well as, greater responsibility in health, nutrition, stress management are greater in those that take breakfast. Finally there was an association between breakfast consumption and better nutrition (p = 0.01) and self-realization (p = 0.005). Consumption of breakfast in older adults is associated with better quality of life. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.

Determinants of Body Mass Index and Intelligence Quotient of Elementary School Children in Mountain Area of Nepal: An Explorative Study

2016-02-01

Full Text Available The physical growth and cognitive development of elementary school children are very crucial and this group is large in number but has little research dedicated to it. The physical growth and cognitive development of children occur simultaneously and can be measured by body mass index (BMI and intelligence quotient (IQ. Previous studies could not sufficiently focus on both aspects. The aim of this study was to identify determinants of BMI and IQ of students in two elementary schools in the Humla district of Nepal. Two randomly selected elementary schools and all children available there (n = 173 participated in the study. BMI was calculated with the objective of proper measurement of height and weight of the children. Likewise, the updated universal nonverbal intelligence test (UNIT was applied for IQ. Descriptive statistics, t-test, analysis of variance and multiple linear regressions were used when appropriate. Study findings showed that one-tenth of the children had grade 2 thinness (-2SD and about one-third had poor IQ (<85. The age of the children (p < 0.05 and household economic status (p < 0.001 were significant for the BMI. Likewise, frequencies of illness in the previous year, mother’s education (p < 0.05 and father’s education (p < 0.001 were significant factors for the IQ score. More commonly, BMI and IQ scores were significantly lower in the ultra-poor group. Economic status and parent education are still major determinants of IQ and BMI in these students. Special programs and strategies should be launched to improve the poor ranking of IQ and BMI.

1994-01-01

To evaluate diagnostic usefulness of ultrasonography(US) in pediatric patient with urinary tract infection. Fifty-five children with urinary tract infection underwent renal ultrasonography and voiding cystourethrography(VCUG). The imaging findings were analyzed retrospectively. Renal sonograms were normal in 34 of 55 children(62%). Five of 34 patients with normal sonogram had vesicoureteral reflux of grade I and III on VCUG. Renal sonograms were abnormal in 21 of 55 children(38%). Sonographic findings included hydronephrosis, hyperechoic kidney, nephromegaly, altrophic kidney, renal abscess, and duplex ureter. Eleven of 21 patient with abnormal sonogram had vesicoureteral reflux of grade I to IV on VCUG. Ultrasonography is an useful and reliable initial screening examination in the investigation of children with UTI. Unfortunately US is neither sufficiently sensitive nor specific for detecting VUR. VCUG provides confirmative and valuable information about vesicoureteral reflux, and VCUG should be considered as a next modality for UTI. The combined use of sonography and VCUG provides more valuable information in urinary tract infection

Analysis of food security level of household is a novelty of measurement standards which usually includes regional and national levels. With household approach is expected to provide the basis of sharp food policy formulation. The purpose of this study are to identify the condition of self-sufficiency in staple foods, and to find the main factors affecting the dynamics of self-sufficiency in staple foods on farm household level in Great Solo. Using primary data from 50 farmers in the sample and secondary data in Great Solo (Surakarta city, Boyolali, Sukoharjo, Karanganyar, Wonogiri, Sragen and Klaten). Compiled panel data were analyzed with linear probability regression models to produce a good model. The results showed that farm households in Great Solo has a surplus of staple food (rice) with an average consumption rate of 96.8 kg/capita/year. This number is lower than the national rate of 136.7 kg/capita/year. The main factors affecting the level of food self-sufficiency in the farmer household level are: rice production, rice consumption, land tenure, and number of family members. Key recommendations from this study are; improvement scale of the land cultivation for rice farming and non-rice diversification consumption.

2015-07-01

Children and young people can be valuable partners in research, giving their unique perspectives on what and how research should be done. However, disabled children are less commonly involved in research than their non-disabled peers. This review investigated how disabled children have been involved as research partners; specifically how they have been recruited, the practicalities and challenges of involvement and how these have been overcome, and impacts of involvement for research, and disabled children and young people. The INVOLVE definition of involvement and the Equality and Human Rights Commission definition of disability were used. Relevant bibliographic databases were searched. Websites were searched for grey literature. Included studies had involved disabled children and young people aged 5-25 years in any study design. Reviews, guidelines, reports and other documents from the grey literature were eligible for inclusion. Twenty-two papers were included: seven reviews, eight original research papers, three reports, three guidelines and one webpage. Nine examples of involvement were identified. Recommendations included developing effective communication techniques, using flexible methods that can be adapted to needs and preferences, and ensuring that sufficient support and funding is available for researchers undertaking involvement. Positive impacts of involvement for disabled children included increased confidence, self-esteem and independence. Positive impacts for research were identified. Involving disabled children in research can present challenges; many of these can be overcome with sufficient time, planning and resources. More needs to be done to find ways to involve those with non-verbal communication. Generally, few details were reported about disabled children and young people's involvement in studies, and the quality of evidence was low. Although a range of positive impacts were identified, the majority of these were authors' opinions rather

Elias, C; Vermeer, A; 't Hart, H

2005-04-01

Little research has been conducted on the perceived competence of children with mild intellectual disabilities (MID). One of the reasons for the marked absence of research appears to be the lack of reliable and clearly valid measurement instruments for this particular group of children. In the present study, it was examined whether a pictorial scale originally designed to measure perceived competence in typically developing children could successfully be used with children with MID. The pictorial scale was administered to a group of 106 children with MID. The construct validity, reliability and stability of the scale were investigated. The results of the exploratory factor analyses and the confirmatory factor analyses supported the conceptual framework proposed. The construct validity was also supported by the pattern of intercorrelations between the subscales. The scale had adequate internal consistency and the stability analyses showed sufficient stability across a 4-month period. The findings show the psychometric properties of the pictorial scale to justify its use with children with MID.

Our results suggest that the prevalence of bone health deficits in children with CP was overestimated, when using only age- and height-adjusted bone mineral content (BMC) and areal bone mineral density (aBMD). When applying the functional muscle-bone unit diagnostic algorithm (FMBU-A), the prevalence of positive results decreased significantly. We recommend applying the FMBU-A when assessing bone health in children with CP. The prevalence of bone health deficits in children with cerebral palsy (CP) might be overestimated because age- and height-adjusted reference percentiles for bone mineral content (BMC) and areal bone mineral density (aBMD) assessed by dual-energy X-ray absorptiometry (DXA) do not consider reduced muscle activity. The aim of this study was to compare the prevalence of positive DXA-based indicators for bone health deficits in children with CP to the prevalence of positive findings after applying a functional muscle-bone unit diagnostic algorithm (FMBU-A) considering reduced muscle activity. The present study was a monocentric retrospective analysis of 297 whole body DXA scans of children with CP. The prevalence of positive results of age- and height-adjusted BMC and aBMD defined as BMC and aBMD below the P3 percentile and of the FMBU-A was calculated. In children with CP, the prevalence of positive results of age-adjusted BMC were 33.3% and of aBMD 50.8%. Height-adjusted results for BMC and aBMD were positive in 16.8 and 36.0% of cases. The prevalence of positive results applying the FMBU-A regarding BMC and aBMD were significantly (p BMC and aBMD (8.8 and 14.8%). Our results suggest that the prevalence of bone health deficits in children with CP was overestimated, when using age- and height-adjusted BMC and aBMD. When applying the FMBU-A, the prevalence decreased significantly. We recommend applying the FMBU-A when assessing bone health in children with CP.

The prevalence of disability among children: paradigms and estimates.

Science.gov (United States)

Mudrick, Nancy R

2002-11-01

Every examination of disability among children must first grapple with definition of disability. The challenges to identifying disability among children involve not only determining the appropriate paradigm for defining disability, but also applying that paradigm to children in a meaningful way. This discussion of the prevalence of disability among children starts by examining the various paradigms utilized to identify disability and how they are interpreted when applied to children. Estimates of the prevalence of childhood disability, under different definitions of disability are presented. The goal of the discussion is to illustrate the sensitivity of the estimates of disability prevalence to the particular definition and data set used. Finally, the potential influence of the choice of paradigm on further measurement and service delivery is outlined.

The purpose of this study was to investigate the effects of distraction on the preoperative anxiety levels of pediatric patients. A prospective, two-group experimental design was used. This study was conducted in the clinic of pediatric surgery of a university hospital in Turkey between November 20, 2013 and January 25, 2014. The population of the study was composed of a total of 83 children (40 in the study group and 43 in the control group) who met the inclusion. The data were collected using the "Personal Information Form," "Separation Scoring," and "State-Trait Anxiety Inventory for Children-State Form." Distraction was performed on the children in the study group during the preoperative period. No intervention was applied to the children in the control group. The results of this study demonstrated that the separation scores and State-Trait Anxiety Inventory for Children-State scores of the children in the study group, on whom distraction was applied, were lower than those of the control group. Distraction applied to children in the preoperative period significantly reduced anxiety and separation anxiety. Copyright © 2016 American Society of PeriAnesthesia Nurses. Published by Elsevier Inc.

The solar house Freiburg which is self-sufficient of energy was completed in October 1992. After a long and complex planning phase now measuring and monitoring tasks as well as the realization fo improvement measures are to the fore. This article presents exemplary results of the first year of operation and compare them with the expectations. Self-sufficient operation of the building could be attained between April and October 1993. Here among others hydrogen was successfully produced by photovoltaic supplied electrolysis and was to a large degree used for thermal applications (cooking, heating). The fact that the supply of energy was not self-sufficient all the year round was due to the failure of the fuel cell used to produce electric power again with hydrogen. (orig./BWI) [de

Source of parental reports of child height and weight during phone interviews and influence on obesity prevalence estimates among children aged 3-17 years.

We compared parental reports of children's height and weight when the values were estimated vs. parent-measured to determine how these reports influence the estimated prevalence of childhood obesity. In the 2007 and 2008 North Carolina Child Health Assessment and Monitoring Program surveys, parents reported height and weight for children aged 3-17 years. When parents reported the values were not measured (by doctor, school, or home), they were asked to measure their child and were later called back. We categorized body mass index status using standard CDC definitions, and we used Chi-square tests and the Stuart-Maxwell test of marginal homogeneity to examine reporting differences. About 80% (n=509) of the 638 parents who reported an unmeasured height and/or weight participated in a callback and provided updated measures. Children originally classified as obese were subsequently classified as obese (67%), overweight (13%), and healthy weight (19%). An estimated 28% of younger children (children (aged ≥10 years) were reclassified on callback. Having parents who guessed the height and weight of their children and then reported updated values did not significantly change the overall population estimates of obesity. Our findings demonstrate that using parent-reported height and weight values may be sufficient to provide reasonable estimates of obesity prevalence. Systematically asking the source of height and weight information may help improve how it is applied to research of the prevalence of childhood obesity when gold-standard measurements are not available.

Schools are an important setting for raising skin cancer prevention awareness and encouraging sun protection. We assessed the clothes worn and shade used by 1,278 children in eight schools in the Wellington region of New Zealand. These children were photographed for the Kids'Cam project between September 2014 and March 2015 during school lunch breaks. Children's mean clothing coverage (expressed as a percentage of body area covered) was calculated. Data on school sun-safety policies were obtained via telephone. Mean total body clothing coverage was 70.3% (95% confidence interval = 66.3%, 73.8%). Body regions with the lowest mean coverage were the head (15.4% coverage), neck (36.1% coverage), lower arms (46.1% coverage), hands (5.3% coverage), and calves (30.1% coverage). Children from schools with hats as part of the school uniform were significantly more likely to wear a hat (52.2%) than children from schools without a school hat (2.7%). Most children (78.4%) were not under the cover of shade. Our findings suggest that New Zealand children are not sufficiently protected from the sun at school. Schools should consider comprehensive approaches to improve sun protection, such as the provision of school hats, sun-protective uniforms, and the construction of effective shade.

To assess the association of neighbourhood sanitation coverage with under-five children's diarrhoeal morbidity and to evaluate its exposure-response relationship. We used the Demographic and Health Surveys (DHS) of 29 developing countries in sub-Saharan Africa and South Asia, conducted between 2010 and 2014. The primary outcome was two-week incidence of diarrhoea in children under 5 years of age (N = 269014). We conducted three-level logistic regression analyses and applied cubic splines to assess the trend between neighbourhood-level coverage of improved household sanitation and diarrhoeal morbidity. A significant association between neighbourhood-level coverage of improved household sanitation and diarrhoeal morbidity (OR [95% CI] = 0.68 [0.62-0.76]) was found. Exposure-relationship analyses results showed improved sanitation coverage threshold at 0.6. We found marginal degree of association (OR [95% CI] = 0.82 [0.77-0.87]) below the threshold, which, beyond the threshold, sharply increased to OR of 0.44 (95% CI: 0.29-0.67) at sanitation coverage of 1 (i.e. neighbourhood-wide use of improved household sanitation). Similar exposure-response trends were identified for urban and rural subgroups. Our findings suggest that neighbourhood sanitation plays a key role in reducing diarrhoeal diseases and that increase in sanitation coverage may only have minimal impact on diarrhoeal illness, unless sufficiently high coverage is achieved. © 2017 John Wiley & Sons Ltd.

Revenue Sufficiency and Reliability in a Zero Marginal Cost Future

Energy Technology Data Exchange (ETDEWEB)

Frew, Bethany A.

2017-04-17

Features of existing wholesale electricity markets, such as administrative pricing rules and policy-based reliability standards, can distort market incentives from allowing generators sufficient opportunities to recover both fixed and variable costs. Moreover, these challenges can be amplified by other factors, including (1) inelastic demand resulting from a lack of price signal clarity, (2) low- or near-zero marginal cost generation, particularly arising from low natural gas fuel prices and variable generation (VG), such as wind and solar, and (3) the variability and uncertainty of this VG. As power systems begin to incorporate higher shares of VG, many questions arise about the suitability of the existing marginal-cost-based price formation, primarily within an energy-only market structure, to ensure the economic viability of resources that might be needed to provide system reliability. This article discusses these questions and provides a summary of completed and ongoing modelling-based work at the National Renewable Energy Laboratory to better understand the impacts of evolving power systems on reliability and revenue sufficiency.

A new assessment method for demonstrating the sufficiency of the safety assessment and the safety margins of the geological disposal system

International Nuclear Information System (INIS)

Ohi, Takao; Kawasaki, Daisuke; Chiba, Tamotsu; Takase, Toshio; Hane, Koji

2013-01-01

A new method for demonstrating the sufficiency of the safety assessment and safety margins of the geological disposal system has been developed. The method is based on an existing comprehensive sensitivity analysis method and can systematically identify the successful conditions, under which the dose rate does not exceed specified safety criteria, using analytical solutions for nuclide migration and the results of a statistical analysis. The successful conditions were identified using three major variables. Furthermore, the successful conditions at the level of factors or parameters were obtained using relational equations between the variables and the factors or parameters making up these variables. In this study, the method was applied to the safety assessment of the geological disposal of transuranic waste in Japan. Based on the system response characteristics obtained from analytical solutions and on the successful conditions, the classification of the analytical conditions, the sufficiency of the safety assessment and the safety margins of the disposal system were then demonstrated. A new assessment procedure incorporating this method into the existing safety assessment approach is proposed in this study. Using this procedure, it is possible to conduct a series of safety assessment activities in a logical manner. (author)

Spirometry in children.

2013-06-01

Respiratory disorders are responsible for considerable morbidity and mortality in children. Spirometry is a useful investigation for diagnosing and monitoring a variety of paediatric respiratory diseases, but it is underused by primary care physicians and paediatricians treating children with respiratory disease. We now have a better understanding of respiratory physiology in children, and newer computerised spirometry equipment is available with updated regional reference values for the paediatric age group. This review evaluates the current literature for indications, test procedures, quality assessment, and interpretation of spirometry results in children. Spirometry may be useful for asthma, cystic fibrosis, congenital or acquired airway malformations and many other respiratory diseases in children. The technique for performing spirometry in children is crucial and is discussed in detail. Most children, including preschool children, can perform acceptable spirometry. Steps for interpreting spirometry results include identification of common errors during the test by applying acceptability and repeatability criteria and then comparing test parameters with reference standards. Spirometry results depict only the pattern of ventilation, which may be normal, obstructive, restrictive, or mixed. The diagnosis should be based on both clinical features and spirometry results. There is a need to encourage primary care physicians and paediatricians treating respiratory diseases in children to use spirometry after adequate training.

Pathogens in Sludge: A Case of Sufficient Challenge

Energy Technology Data Exchange (ETDEWEB)

Lesilind, R. Aarne

2003-07-01

There is increasing pressure in many countries to strengthen the regulations controlling the land disposal of wastewater sludges. In this paper I argue that although there is little doubt that sludges from wastewater treatment contain pathogenic organisms, not only are there no data to show that such disposal is a public health problem, but I want to suggest that small doses of pathogens in the environment provide a ''sufficient challenge'' that actually enhances public health. There therefore seems little reason, from a public health standpoint, to pass stricter sludge disposal regulations. (author)

Yang, Ji Yeon; Lee, Hanna; Zhang, Yongai; Lee, Ji Uhn; Park, Jun Hee; Yun, Eun Kyoung

2016-11-01

Tonsillectomy is the most common type of surgical procedure performed in preschool children. Due to short period of hospitalization, mothers are expected to manage their children's care at home. However, they are rarely provided with sufficient information about postoperative management. This study aims to determine the effectiveness of providing caregivers with information on tonsillectomy care by smartphone text messaging in increasing their mothers' knowledge, reducing the anxiety, and improving the sick-role behavior of pediatric tonsillectomy patients. A sample of 61 pediatric patients and their mothers was recruited. Participants were randomly assigned into either the experimental group (n = 27) or the control group (n = 34). The control group was given information about the tonsillectomy by conventional textual and verbal means, whereas the experimental group received the same information in the form of 10 text messages during the period from hospitalization to their first follow-up visits. Results of mixed design, two-way analysis of variance indicated significant interaction effects between time points and groups for mothers' knowledge (F = 4.26, p = 0.043) and children's anxiety (F = 3.32; p = 0.037). Thus, the results do support the effectiveness of tonsillectomy education using smartphone text messaging in increasing mothers' knowledge and reducing children's anxiety. These results can be applied to preoperative and postoperative interventions for children not only for tonsillectomy but also for many other operations. The development of various educational programs using smartphone text messaging for postoperative patient management would also be valuable.

The importance of spatial orientation and knowledge of traffic signs for children's traffic safety.

Science.gov (United States)

Trifunović, Aleksandar; Pešić, Dalibor; Čičević, Svetlana; Antić, Boris

2017-05-01

Pre-school children, as well as children from lower grades in primary school, who although rarely, completely independently participate in traffic, represent a vulnerable population from the standpoint of traffic safety. The greatest number of children were injured or killed in road traffic crashes on their way from home to kindergarten or school. Mostly due to lack of experience, children's behavior is confusing and often reckless and hasty. Safe behavior in the traffic environment demands certain cognitive skills. Unlike adults, children have less than fully developed peripheral vision. Also, changes occur in color perception, i.e. discrimination. All this leads to the conclusion that the stage of physical and mental development of the child is very important for safe participation in traffic. So, to estimate if they are sufficiently equipped to participate safely in traffic, a sensitive test for young children that may be suitable for their level of cognitive development is required. Accordingly, road safety education should be arranged in such a way that considers the child's level of development, as has been shown to be more effective when started at younger ages. Play is the most natural and easiest way of learning because it is the lens through which children experience their world, and the world of others. Having this in mind, if we want to measure the abilities of a child, and their preparedness for safety participation in traffic, unavoidable is to use non-verbal tests. The purpose of this study is to explore primary schooler's spatial, and abilities of color perception and memorization, as well as their performances in interpreting the meaning of traffic signs. In addition, neighborhood environmental correlates (rural-urban) and possible individual differences influences on the relationship among these abilities was examined. Knowledge about these factors affecting children's safety can be applied to improve relevant intervention measures for promoting

CaFe2O4 as a self-sufficient solar energy converter

Science.gov (United States)

Tablero, C.

2017-10-01

An ideal solar energy to electricity or fuel converter should work without the use of any external bias potential. An analysis of self-sufficiency when CaFe2O4 is used to absorb the sunlight is carried out based on the CaFe2O4 absorption coefficient. We started to obtain this coefficient theoretically within the experimental bandgap range in order to fix the interval of possible values of photocurrents, maximum absorption efficiencies, and photovoltages and thus that of self-sufficiency considering only the radiative processes. Also for single-gap CaFe2O4, we evaluate an alternative for increasing the photocurrent and maximum absorption efficiency based on inserting an intermediate band using high doping or alloying.

The purpose of this survey was to determine the association of parents' attitudes and behaviors toward children's visual care with myopia risk in school-aged children.A total of 894 parents of school-aged children were investigated in primary and middle schools in the central and noncentral urban area in Wuhan through stratified cluster random sampling on July, 2015. We analyzed the association by the generalized linear mixed model.The results indicated that children with parents' high expectations of 1.5 or higher on their vision exhibited a decreased risk of myopia compared with 1.0 and 0.5 or lower (OR = 0.49, 95%CI = 0.36-0.67). Children whose parents only paid attention to their vision in junior and senior school and in primary school had an increased myopia risk than that in preschool (OR = 2.12, 95%CI = 1.01-4.45, and OR = 3.11, 95%CI = 1.28-7.58, respectively). Children whose parents ensured for their sufficient sleep had a decreased myopia risk (OR = 0.45, 95%CI = 0.24-0.85). Compared with children whose parents who never adjusted electronic devices' parameters, the odds ratio of sometimes was 0.49 (95%CI = 0.31-0.79), often 0.53 (95%CI = 0.33-0.85), and always 0.44 (95%CI = 0.26-0.75), respectively.Parents' attitudes and behaviors toward children's visual care are significantly associated with the myopia risk in school-aged children. Consequently, efforts should be made to educate parents on how they protect children's vision and reduce their risk of myopia. Copyright © 2017 The Authors. Published by Wolters Kluwer Health, Inc.

A simple, sufficient, and consistent method to score the status of threats and demography of imperiled species

Directory of Open Access Journals (Sweden)

Jacob W. Malcom

2016-07-01

Full Text Available Managers of large, complex wildlife conservation programs need information on the conservation status of each of many species to help strategically allocate limited resources. Oversimplifying status data, however, runs the risk of missing information essential to strategic allocation. Conservation status consists of two components, the status of threats a species faces and the species’ demographic status. Neither component alone is sufficient to characterize conservation status. Here we present a simple key for scoring threat and demographic changes for species using detailed information provided in free-form textual descriptions of conservation status. This key is easy to use (simple, captures the two components of conservation status without the cost of more detailed measures (sufficient, and can be applied by different personnel to any taxon (consistent. To evaluate the key’s utility, we performed two analyses. First, we scored the threat and demographic status of 37 species recently recommended for reclassification under the Endangered Species Act (ESA and 15 control species, then compared our scores to two metrics used for decision-making and reports to Congress. Second, we scored the threat and demographic status of all non-plant ESA-listed species from Florida (54 spp., and evaluated scoring repeatability for a subset of those. While the metrics reported by the U.S. Fish and Wildlife Service (FWS are often consistent with our scores in the first analysis, the results highlight two problems with the oversimplified metrics. First, we show that both metrics can mask underlying demographic declines or threat increases; for example, ∼40% of species not recommended for reclassification had changes in threats or demography. Second, we show that neither metric is consistent with either threats or demography alone, but conflates the two. The second analysis illustrates how the scoring key can be applied to a substantial set of species to

Does school breakfast benefit children's educational performance?

Science.gov (United States)

Fernald, L; Ani, C C; Grantham-mcgregor, S

1997-09-01

This article reviews several research studies on the impact of the lack of breakfast among students. Recent data reveal that about 20% of Nigerian children were wasted or had weight-for-height measurements under the 5th percentile of the US National Center for Health Statistics (NCHS) standard. In Ghana, 41% of children were underweight or had a weight-for-age under -2 standard deviations of the NCHS standards. In Tanzania, about 34% of children were underweight. Many more students in Africa are attending school, but many are leaving primary school early or failing secondary school examinations. It is argued that poor nutritional status affects children's ability to learn. Research reveals several hypotheses about how breakfast affects children's cognition, behavior, and school performance. Children may not attend school at all due to the inability to purchase food to eat at school, or insufficient food resources at home to provide sufficient energy to walk long distances to school. In four studies, two in the USA and the others in Peru and Jamaica, findings reveal that when undernourished children missed breakfast, they performed worse in tests of cognition. Adequately nourished children's performance was unaffected by missing breakfast. A study in four Jamaican schools found that children had more creative ideas when they received a breakfast for 2 weeks than when they did not receive breakfast. Two Swedish studies found that children with a high-calorie breakfast improved in cognition compared to those receiving a low-calorie breakfast. One study found that children in well-equipped classrooms paid more attention in class after having breakfast. Children in overcrowded classes and poorly equipped schools were less likely to pay attention after breakfast. Long-term effects are less well studied, but findings clearly support the benefits of breakfast.

Sufficient and necessary condition of separability for generalized Werner states

International Nuclear Information System (INIS)

Deng Dongling; Chen Jingling

2009-01-01

In a celebrated paper [Optics Communications 179, 447, 2000], A.O. Pittenger and M.H. Rubin presented for the first time a sufficient and necessary condition of separability for the generalized Werner states. Inspired by their ideas, we generalized their method to a more general case. We obtain a sufficient and necessary condition for the separability of a specific class of N d-dimensional system (qudits) states, namely special generalized Werner state (SGWS): W [d N ] (v)=(1-v)(I (N) )/(d N ) +v|ψ d N > d N |, where |ψ d N >=Σ i=0 d-1 α i |i...i> is an entangled pure state of N qudits system and α i satisfies two restrictions: (i) Σ i=0 d-1 α i α i *=1; (ii) Matrix 1/d (I (1) +TΣ i≠j α i |i> j *), where T=Min i≠j {1/|α i α j |}, is a density matrix. Our condition gives quite a simple and efficiently computable way to judge whether a given SGWS is separable or not and previously known separable conditions are shown to be special cases of our approach

[Risk assessment expanded accident insurance for children].

Science.gov (United States)

Sittaro, N A

1998-08-01

Disability is a well known and tragic event for children. While adults are an established group for specific disability insurance cover, children were often neglected in the past. Although parents, organizations and paediatricans are aware of the risk, children specific incidence rates for disability are hardly available. The only sufficient source for some statistical data are the accident statistics because they represent a substantial group of specific cause related disability for children. Incidence rates for disease related chronic severe impairment or disability in children are either derived by single disease research or actuarial calculation of the German Social Disability Registration. Based on this statistical background, an extended accident insurance for children was introduced in Germany covering both accidents and disabling diseases. The key limitation for all variations of this insurance are exclusion clauses for congential diseases and mental disorders. This insurance requires a new approach in underwriting of the health risks. Because of the substantial number of impaired children, a simple decline of substandard cases are unacceptable. The early experience or medical underwriting shows predominantly health impairments of the following types: allergies, bronchial asthma, ectopic eczema (neurodermitis), disorders of speech and articulation, vision disorders and mental impairments. The suggested solution for underwriting of substandard risks is the predetermination of the possible future maximum degree of disability. The need for underwriting guidelines is supported by the market impact of the new disability cover with thousands of insurance policies issued in the first month after introduction.

Possibilities and limitations of applying software reliability growth models to safety-critical software

International Nuclear Information System (INIS)

Kim, Man Cheol; Jang, Seung Cheol; Ha, Jae Joo

2007-01-01

It is generally known that software reliability growth models such as the Jelinski-Moranda model and the Goel-Okumoto's Non-Homogeneous Poisson Process (NHPP) model cannot be applied to safety-critical software due to a lack of software failure data. In this paper, by applying two of the most widely known software reliability growth models to sample software failure data, we demonstrate the possibility of using the software reliability growth models to prove the high reliability of safety-critical software. The high sensitivity of a piece of software's reliability to software failure data, as well as a lack of sufficient software failure data, is also identified as a possible limitation when applying the software reliability growth models to safety-critical software

2017-07-10

Background : Post-earthquake studies from around the world have reported that survivors relying on emergency food for prolonged periods of time experienced several dietary related health problems. The present study aimed to quantify the potential nutrient production of urban agricultural vegetables and the resulting nutritional self-sufficiency throughout the year for mitigating post-disaster situations. Methods : We estimated the vegetable production of urban agriculture throughout the year. Two methods were developed to capture the production from professional and hobby farms: Method I utilized secondary governmental data on agricultural production from professional farms, and Method II was based on a supplementary spatial analysis to estimate the production from hobby farms. Next, the weight of produced vegetables [t] was converted into nutrients [kg]. Furthermore, the self-sufficiency by nutrient and time of year was estimated by incorporating the reference consumption of vegetables [kg], recommended dietary allowance of nutrients per capita [mg], and population statistics. The research was conducted in Nerima, the second most populous ward of Tokyo's 23 special wards. Self-sufficiency rates were calculated with the registered residents. Results : The estimated total vegetable production of 5660 tons was equivalent to a weight-based self-sufficiency rate of 6.18%. The average nutritional self-sufficiencies of Methods I and II were 2.48% and 0.38%, respectively, resulting in an aggregated average of 2.86%. Fluctuations throughout the year were observed according to the harvest seasons of the available crops. Vitamin K (6.15%) had the highest self-sufficiency of selected nutrients, while calcium had the lowest (0.96%). Conclusions : This study suggests that depending on the time of year, urban agriculture has the potential to contribute nutrients to diets during post-disaster situations as disaster preparedness food. Emergency responses should be targeted

MSEBAG: a dynamic classifier ensemble generation based on `minimum-sufficient ensemble' and bagging

Science.gov (United States)

Chen, Lei; Kamel, Mohamed S.

2016-01-01

In this paper, we propose a dynamic classifier system, MSEBAG, which is characterised by searching for the 'minimum-sufficient ensemble' and bagging at the ensemble level. It adopts an 'over-generation and selection' strategy and aims to achieve a good bias-variance trade-off. In the training phase, MSEBAG first searches for the 'minimum-sufficient ensemble', which maximises the in-sample fitness with the minimal number of base classifiers. Then, starting from the 'minimum-sufficient ensemble', a backward stepwise algorithm is employed to generate a collection of ensembles. The objective is to create a collection of ensembles with a descending fitness on the data, as well as a descending complexity in the structure. MSEBAG dynamically selects the ensembles from the collection for the decision aggregation. The extended adaptive aggregation (EAA) approach, a bagging-style algorithm performed at the ensemble level, is employed for this task. EAA searches for the competent ensembles using a score function, which takes into consideration both the in-sample fitness and the confidence of the statistical inference, and averages the decisions of the selected ensembles to label the test pattern. The experimental results show that the proposed MSEBAG outperforms the benchmarks on average.

Is a single dose of meningococcal serogroup C conjugate vaccine sufficient for protection? experience from the Netherlands

Directory of Open Access Journals (Sweden)

Kaaijk Patricia

2012-02-01

Full Text Available Abstract Background The first meningococcal serogroup C (MenC conjugate vaccine was licensed in 1999 and introduced in the United Kingdom. Countries that have implemented the MenC vaccine since then in their national immunisation programmes use different schedules. Nevertheless, all involved countries seem to experience substantial declines in the incidence of MenC disease. Discussion Since 2001, the MenC conjugate vaccine has been implemented in the Netherlands by offering a single dose to all children aged 14 months. Prior to the introduction of the vaccine into the national immunisation programme, a catch-up vaccination campaign was initiated in which a single dose of the MenC conjugate vaccine was offered to all children aged from 14 months up to and including 18 years. Since then, there has been no report of any case of MenC disease among immunocompetent vaccinees. Administration of a single dose of MenC conjugate vaccine after infancy could be beneficial considering the already complex immunisation schedules with large numbers of vaccinations in the first year of life. The present paper deals with the advantages and critical aspects of a single dose of the MenC conjugate vaccine. Summary A single dose of MenC conjugate vaccine at the age of 14 months in combination with a catch up vaccine campaign appeared to be a successful strategy to prevent MenC disease in the Netherlands, thereby confirming that a single dose of the vaccine could sufficiently protect against disease. Nevertheless, this approach can only be justified in countries with a relatively low incidence of serogroup C meningococcal disease in the first year of life. Furthermore, a good surveillance programme is recommended for timely detection of vaccine breakthroughs and outbreaks among non-vaccinees, since long-term protection after a single dose in the second year of life cannot currently be guaranteed.

Tamas, Daniela; Marković, Slavica; Milankov, Vesela

2013-01-01

Conditions in which speech therapy treatment is applied in autistic children are often not in accordance with characteristics of opinions and learning of people with autism. A systemic multimodal approach means motivating autistic people to develop their language speech skill through the procedure which allows reliving of their personal experience according to the contents that are presented in the their natural social environment. This research was aimed at evaluating the efficiency of speech treatment based on the systemic multimodal approach to the work with autistic children. The study sample consisted of 34 children, aged from 8 to 16 years, diagnosed to have different autistic disorders, whose results showed a moderate and severe clinical picture of autism on the Childhood Autism Rating Scale. The applied instruments for the evaluation of ability were the Childhood Autism Rating Scale and Ganzberg II test. The study subjects were divided into two groups according to the type of treatment: children who were covered by the continuing treatment and systemic multimodal approach in the treatment, and children who were covered by classical speech treatment. It is shown that the systemic multimodal approach in teaching autistic children affects the stimulation of communication, socialization, self-service and work as well as that the progress achieved in these areas of functioning was retainable after long time, too. By applying the systemic multimodal approach when dealing with autistic children and by comparing their achievements on tests applied before, during and after the application of this mode, it has been concluded that certain improvement has been achieved in the functionality within the diagnosed category. The results point to a possible direction in the creation of new methods, plans and programs in dealing with autistic children based on empirical and interactive learning.

To assess the vitamin D status of children aged 6-10years in the French general population for whom no guidelines have yet been defined due to insufficient data. The study was conducted during two winters with very different sunshine levels: 5 March to 17 April 2012 and 8 January to 16 April 2013 in 20 then 22 centers. Three hundred children (60 children for each year of age) attending an ambulatory care unit or outpatient department for a reason unrelated to vitamin D status were included at the end of winter in 20 hospital centers (ten centers in the northern half of France above latitude 46-47°N/Lille: 50°N and ten centers in the southern half of France below latitude 46-47°N/Marseille: 43°N). Centralized 25 hydroxyvitamin D (25(OH)D), alkaline phosphatase (ALP), and parathormone (PTH) assays were performed on leftover blood samples. The currently accepted normal range for 25(OH)D was used to define the following categories: ≤25nmol/L: severe vitamin D deficiency, 25nmol/Lvitamin D deficiency≤50nmol/L, 50nmol/Lvitamin D status≤100nmol/L, >100nmol/L: high vitamin D status. A standardized questionnaire was used to collect the child's characteristics, use of a vitamin D supplement, and milk and dairy product intake. The cumulative number of hours of sunshine over the 90days prior to inclusion in each center was obtained from the Météo-France weather bureau. 25(OH)D assays were performed in 326 children; more than 95% of children received milk and dairy products and 38% had received a vitamin D supplement since starting the school year: 3.1% of children in the overall population presented severe vitamin D deficiency, 34.4% presented vitamin D deficiency, 53.1% had a sufficient vitamin D status, and 9.5% had a 25(OH)D concentration >100nmol/L with no impact on serum calcium and urinary calcium. Children living in the north of France generally had lower 25(OH)D levels than children living in the south of France. In the non-supplemented population (n=188

Conventional extracorporeal photopheresis (ECP) has proven efficacy for the treatment of several diseases but is limited to patients with sufficient body weight. A novel simplified mini buffy coat ECP technique that allows treatment of small children and patients with apheresis contraindications has been developed. White blood cell (WBC)-rich buffy coat fractions were prepared from 5 to 8 mL/kg whole blood in a closed system, diluted, and ultraviolet A (UVA)-irradiated after addition of 8-methoxypsoralen (8-MOP). Apoptosis and cell death were analyzed by annexin V and 7-aminoactinomycin staining. Lymphocyte proliferation was measured after CD3/CD28 and phytohemagglutinin (PHA) stimulation. Autologous residual blood and UVA-irradiated buffy coat were returned to the patients. Fifty-six mini buffy coat ECP procedures were applied to three children with acute steroid-refractory skin graft-versus-host disease and apheresis contraindications. Mean whole blood and buffy coat volumes were 166 (+/-61.8) and 8 (+/-1.6) mL, respectively, and resulted in a hematocrit of 2.2% (+/-0.4) after saline dilution (median +/- SD). UVA irradiation of 8-MOP buffy coat preparations resulted in significant induction of WBC apoptosis at 48-72 hours (p laboratory side effects were observed during mini ECP procedures and the three patients responded to the therapy. Mini buffy coat ECP induces apoptosis and lymphocyte proliferation inhibition, both of which occur after standard ECP. This study proposes that mini buffy coat ECP be used as a simple and inexpensive alternative to classical ECP in children and adult patients with apheresis contraindications.

To identify the association of dietary, socioeconomic factors, sedentary behaviors and maternal nutritional status with abdominal obesity in children. A cross-sectional study with household-based survey, in 36 randomly selected census tracts in the city of Santos/SP. 357 families were interviewed and questionnaires and anthropometric measurements were applied in mothers and their 3-0 years-old children. Assessment of abdominal obesity was made by maternal and child's waist circumference measurement; for classification used cut-off points proposed by World Health Organization (1998) and Taylor et al. (2000) were applied. The association between variables was performed by multiple logistic regression analysis. 30.5% of children had abdominal obesity. Associations with children's and maternal nutritional status and high socioeconomic status were shown in the univariate analysis. In the regression model, children's body mass index for age (OR=93.7; 95%CI 39.3-223.3), female gender (OR=4.1; 95%CI 1.8-9.3) and maternal abdominal obesity (OR=2.7; 95%CI 1.2-6.0) were significantly associated with children's abdominal obesity, regardless of the socioeconomic status. Abdominal obesity in children seems to be associated with maternal nutritional status, other indicators of their own nutritional status and female gender. Intervention programs for control of childhood obesity and prevention of metabolic syndrome should consider the interaction of the nutritional status of mothers and their children.

Features of existing wholesale electricity markets, such as administrative pricing rules and policy-based reliability standards, can distort market incentives from allowing generators sufficient opportunities to recover both fixed and variable costs. Moreover, these challenges can be amplified by other factors, including (1) inelastic demand resulting from a lack of price signal clarity, (2) low- or near-zero marginal cost generation, particularly arising from low natural gas fuel prices and variable generation (VG), such as wind and solar, and (3) the variability and uncertainty of this VG. As power systems begin to incorporate higher shares of VG, many questions arise about the suitability of the existing marginal-cost-based price formation, primarily within an energy-only market structure, to ensure the economic viability of resources that might be needed to provide system reliability. This article discusses these questions and provides a summary of completed and ongoing modelling-based work at the National Renewable Energy Laboratory to better understand the impacts of evolving power systems on reliability and revenue sufficiency.

Correlation, necessity, and sufficiency: Common errors in the scientific reasoning of undergraduate students for interpreting experiments.

Science.gov (United States)

Coleman, Aaron B; Lam, Diane P; Soowal, Lara N

2015-01-01

Gaining an understanding of how science works is central to an undergraduate education in biology and biochemistry. The reasoning required to design or interpret experiments that ask specific questions does not come naturally, and is an essential part of the science process skills that must be learned for an understanding of how scientists conduct research. Gaps in these reasoning skills make it difficult for students to become proficient in reading primary scientific literature. In this study, we assessed the ability of students in an upper-division biochemistry laboratory class to use the concepts of correlation, necessity, and sufficiency in interpreting experiments presented in a format and context that is similar to what they would encounter when reading a journal article. The students were assessed before and after completion of a laboratory module where necessary vs. sufficient reasoning was used to design and interpret experiments. The assessment identified two types of errors that were commonly committed by students when interpreting experimental data. When presented with an experiment that only establishes a correlation between a potential intermediate and a known effect, students frequently interpreted the intermediate as being sufficient (causative) for the effect. Also, when presented with an experiment that tests only necessity for an intermediate, they frequently made unsupported conclusions about sufficiency, and vice versa. Completion of the laboratory module and instruction in necessary vs. sufficient reasoning showed some promise for addressing these common errors. © 2015 The International Union of Biochemistry and Molecular Biology.

To verify if there are characteristic behaviors of the different diagnosis included in the autism spectrum according to the Differential Assessment of Autism and Other Developmental Disorders (DAADD) and to the Autism Behavior Checklist (ABC). Participants were 45 individuals and their respective speech-language therapists. All therapists are graduate students working with the children for at least 1 year. This time was considered sufficient to the therapists to have the information required by the DAADD questionnaire. It is comprised by 3 protocols specifically designed to children with 2 to 4 years, 4 to 6 years and 6 to 8 years, the same criteria used to separate the research groups, G1, G2 and G3, respectively. Data referring to the ABC were retrieved from the subject's files at the Laboratório de Investigação Fonoaudiológica nos Distúrbios do Espectro do Autismo (Research Laboratory on Language Disorders in the Autism Spectrum) of the School of Medicine, Universidade de São Paulo, where it is routinely applied during the annual assessment. Answers to the different areas of DAADD are similar to the different areas of ABC. These data show data the diagnosis by DAADD is easier in older children. Although there is no significant difference, the large occurrence of Rett's syndrome diagnosis according to the DAADD was associated to higher risk for autism according to the ABC in G1. With increasing age this tendency decreases and either in G2 and G3 Autism is the most frequent diagnosis. Although the results of both questionnaires tend to agree more with increasing age, the DAADD is more sensitive in the different ages while the ABC if more specific only to older children.

2018-01-01

Research on media induced food choices of children has not sufficiently investigated whether food placements of snacks high in nutritional value can strengthen children's healthy eating behavior. Furthermore, we lack knowledge about the moderating role of children's individual characteristics such as parental food-related mediation or BMI. The current study combines data from an experiment involving children with a survey of their parents. We exposed children to a cartoon either containing no food placements, placements of mandarins (i.e., snack high in nutritional value), or placements of fruit gums (i.e., snack low in nutritional value). Afterwards, food consumption was measured by giving children the option to choose between fruit gums or mandarins. Children in both snack placement conditions showed stronger preference for the snack low in nutritional value (i.e., fruit gum) compared to the control group. Interestingly, neither restrictive nor active food-related mediation prevented the effects of the placements on children's choice of snacks low in nutritional value. Compared to children with a low BMI, children with high BMI levels had a stronger disposition to choose the fruit gums if a snack high in nutritional value (i.e., mandarin) was presented. Thus, making snacks high in nutritional attractive for children through media presentation might need stronger persuasive cues. Copyright © 2017 Elsevier Ltd. All rights reserved.

Food Self-Sufficiency across scales: How local can we go?

Science.gov (United States)

Pradhan, Prajal; Lüdeke, Matthias K. B.; Reusser, Dominik E.; Kropp, Jürgen P.

2013-04-01

"Think global, act local" is a phrase often used in sustainability debates. Here, we explore the potential of regions to go for local supply in context of sustainable food consumption considering both the present state and the plausible future scenarios. We analyze data on the gridded crop calories production, the gridded livestock calories production, the gridded feed calories use and the gridded food calories consumption in 5' resolution. We derived these gridded data from various sources: Global Agro-ecological Zone (GAEZ v3.0), Gridded Livestock of the World (GLW), FAOSTAT, and Global Rural-Urban Mapping Project (GRUMP). For scenarios analysis, we considered changes in population, dietary patterns and possibility of obtaining the maximum potential yield. We investigate the food self-sufficiency multiple spatial scales. We start from the 5' resolution (i.e. around 10 km x 10 km in the equator) and look at 8 levels of aggregation ranging from the plausible lowest administrative level to the continental level. Results for the different spatial scales show that about 1.9 billion people live in the area of 5' resolution where enough calories can be produced to sustain their food consumption and the feed used. On the country level, about 4.4 billion population can be sustained without international food trade. For about 1 billion population from Asia and Africa, there is a need for cross-continental food trade. However, if we were able to achieve the maximum potential crop yield, about 2.6 billion population can be sustained within their living area of 5' resolution. Furthermore, Africa and Asia could be food self-sufficient by achieving their maximum potential crop yield and only round 630 million populations would be dependent on the international food trade. However, the food self-sufficiency status might differ under consideration of the future change in population, dietary patterns and climatic conditions. We provide an initial approach for investigating the

High spatial validity is not sufficient to elicit voluntary shifts of attention.

Science.gov (United States)

Pauszek, Joseph R; Gibson, Bradley S

2016-10-01

Previous research suggests that the use of valid symbolic cues is sufficient to elicit voluntary shifts of attention. The present study interpreted this previous research within a broader theoretical context which contends that observers will voluntarily use symbolic cues to orient their attention in space when the temporal costs of using the cues are perceived to be less than the temporal costs of searching without the aid of the cues. In this view, previous research has not addressed the sufficiency of valid symbolic cues, because the temporal cost of using the cues is usually incurred before the target display appears. To address this concern, 70%-valid spatial word cues were presented simultaneously with a search display. In addition, other research suggests that opposing cue-dependent and cue-independent spatial biases may operate in these studies and alter standard measures of orienting. After identifying and controlling these opposing spatial biases, the results of two experiments showed that the word cues did not elicit voluntary shifts of attention when the search task was relatively easy but did when the search task was relatively difficult. Moreover, the findings also showed that voluntary use of the word cues changed over the course of the experiment when the task was difficult, presumably because the temporal cost of searching without the cue lessened as the task got easier with practice. Altogether, the present findings suggested that the factors underlying voluntary control are multifaceted and contextual, and that spatial validity alone is not sufficient to elicit voluntary shifts of attention.

The wheat crop in Sao Paulo State, Brazil, is fertilized with N, P and K. The rate of applied N (0 to 120 kg.ha -1 ) depends on the previous grown crop and the irrigation possibility. The response of wheat to rates and time of N application and the fate of N applied to irrigated wheat were studied during two years. Residual N recovery by soybean grown after the wheat was also studied. The maximum grain productivity was obtained with 92 kg.ha -1 of N. The efficiency of 15 N-urea utilization ranged from 52% to 85%. The main loss of applied 15 N, 5% to 12% occurred as ammonia volatilized from urea applied on soil surface. The N loss by leaching even at the N rate of 135 kg.ha -1 , was less than 1% of applied 15 N, due to the low amount of rainfall during the wheat grown season and a controlled amount of irrigated water, that were sufficient to moisten only the wheat root zone. The residual 15 N after wheat harvest represents around 40% of N applied as urea: 20% in soil, 3% in wheat root system and 16% in the wheat straw. Soybean recovered less than 2% of the 15 N applied to wheat at sowing or at tillering stage. (author)

Children's perceived cost for exercise: application of an expectancy-value paradigm.

Science.gov (United States)

Chiang, Evelyn S; Byrd, Sandra P; Molin, Ashley J

2011-04-01

Expectancy-value models of motivation have been applied to understanding children's choices in areas such as academics and sports. Here, an expectancy-value paradigm is applied to exercising (defined as engaging in physical activity). The notion of perceived cost is highlighted in particular. Two hundred twenty children in third, fourth, and fifth grades were surveyed on their competence beliefs, perceived importance, interest, and perceived cost of being physically active. Results indicated that perceived cost is empirically distinct from competence beliefs and other types of value, that perceived cost is marginally related to children's self-reported level of physical activity, and children's beliefs and other values are related to their self-reported level of physical activity. Children's perceptions of cost vary depending on grade and gender. Interventions based on these findings are proposed.

Noncaloric Sweeteners in Children: A Controversial Theme

Directory of Open Access Journals (Sweden)

Samuel Durán Agüero

2018-01-01

Full Text Available Noncaloric sweeteners (NCS are food additives used to provide sweetness without adding calories. Their consumption has become more widespread around the world in all age groups, including children. The aim of this study is to show the state of the art about the intake of noncaloric sweeteners in children, as well as their benefits and consumption risk. Scientific searchers were used (PUBMED, Scopus, and Scielo to analyze articles that included keywords (noncaloric sweeteners/saccharin/cyclamate/acesulfame potassium/aspartame/sucralose/stevia/children in English, Spanish, and Portuguese. Authors conclude that it is imperative that health professionals judiciously and individually evaluate the overall benefits and risks of NCS use in consumers before recommending their use. Different subgroups of the population incorporate products containing NCS in their diet with different objectives, which should be considered when recommending a diet plan for the consumer. In childhood, in earlier age groups, this type of additives should be used as a dietary alternative when other forms of prevention in obesity are not sufficient.

Lin, Fang-Yi; Rong, Jiin-Ru; Lee, Tzu-Ying

2013-08-29

The purpose of this concept analysis is to uncover the essential elements involved in caregivers' resilience in the context of caring for children with chronic conditions. Walker and Avant's methodology guided the analysis. The study includes a literature review of conceptual definitions of caregiver resilience in caring for children with chronic conditions. The defining attributes and correlates of caregiver resilience are reviewed. Concept analysis findings in a review of the nursing and health-related literature show that caregiver resilience in the context of caring for chronically ill children can be defined within four main dimensions, ie, disposition patterns, situational patterns, relational patterns, and cultural patterns. Empiric measurements of the impact of caregiver resilience applied to caregivers with children with chronic conditions are also reported in the analysis. The findings of this concept analysis could help nurses and health care providers to apply the concept of caregiver resilience in allied health care and be applied to further studies.

Internal urethrotomy for recurrence after perineal anastomotic urethroplasty for posttraumatic pediatric posterior urethral stricture: could it be sufficient?

Helmy, Tamer E; Hafez, Ashraf T

2013-06-01

To evaluate the long-term outcome of visual internal urethrotomy (VIU) after perineal anastomotic urethroplasty for posttraumatic pediatric posterior urethral strictures. Data of 22 boys who had undergone internal urethrotomy for recurrent stricture after perineal anastomotic urethroplasty for posttraumatic posterior urethral strictures between 1998 and 2008 were analyzed retrospectively regarding patient age, interval between anastomotic urethroplasty and internal urethrotomy, stricture length, surgical technique, and postoperative complications. VIU was performed in patients in whom a guidewire could be passed beyond the stricture segment. The eventual surgical success was defined as asymptomatic voiding without clinical evidence of residual stricture (good flow rate and absence of residual urine). The mean (range) age of patients was 12.2 (3-17) years. All patients had a road traffic accident with associated pelvic fracture. The perineal approach for anastomotic urethroplasty was adopted in all. The estimated stricture length was 0.5 cm or less in 15 patients and was 0.5 to 1 cm in 7 patients. The interval between anastomotic urethroplasty and internal urethrotomy was early-after 12 weeks or less-in 13 children or late-beyond 12 weeks-in the remaining 9. The overall mean interval was 18 (5-63) weeks. In all patients, a guidewire could be passed through the strictured area. One VIU was performed in 17 patients, 2 VIU in 3 patients, while 3 VIU were performed in 2 patients. There was no extravasation reported. The mean follow-up duration was 98 (38-210) months. VIU was successful in 20 of 22 (90%) patients. All patients voided with no symptoms and were continent. VIU offers high success rate and can be sufficient in recurrent strictures of less than 1 cm length after anastomotic urethroplasty in children whenever a guidewire can be passed through the stricture area.

Vocal cord paralysis in children.

Science.gov (United States)

King, Ericka F; Blumin, Joel H

2009-12-01

Vocal fold paralysis (VFP) is an increasingly commonly identified problem in the pediatric patient. Diagnostic and management techniques honed in adult laryngologic practice have been successfully applied to children. Iatrogenic causes, including cardiothoracic procedures, remain a common cause of unilateral VFP. Neurologic disorders predominate in the cause of bilateral VFP. Diagnosis with electromyography is currently being evaluated in children. Treatment of VFP is centered around symptomology, which is commonly divided between voice and airway concerns. Speech therapy shows promise in older children. Surgical management for unilateral VFP with injection laryngoplasty is commonly performed and well tolerated. Laryngeal reinnervation is currently being applied to the pediatric population as a permanent treatment and offers several advantages over laryngeal framework procedures. For bilateral VFP, tracheotomy is still commonly performed. Glottic dilation procedures are performed both openly and endoscopically with a high degree of success. VFP is a well recognized problem in pediatric patients with disordered voice and breathing. Some patients will spontaneously recover their laryngeal function. For those who do not, a variety of reliable techniques are available for rehabilitative treatment.

School-aged children (n = 48,118 reported their physical activity, perception of physical activity sufficiency, factors for activity insufficiency, homework hours, and screen time in a typical week. Data were analyzed using general linear models and logistic regression models of Complex Samples. Prevalence results showed that children had lower physical activity and lower screen viewing time, but higher homework time during transition grades (6th, 9th, and 12th and high school years. Academic burden was cited as the primary reason for not having sufficient physical activity (76.6%. Compared to those citing academic burden, students who did not report academic burden were significantly more likely to meet physical activity guidelines (Odds Ratio (OR = 5.38, 95% CI = 4.74–6.11, but less likely to meet screen time guidelines (OR = 0.78, 95% CI = 0.72–0.84, controlling for body mass index, gender, and grade level. Additionally, children who reported academic burdens had significantly longer average daily homework time than those who did not (p<0.01. Policy makers should promote physical activity and help children find a balance between homework and physical activity time particularly among the educational transition grades.

Sonic hedgehog in the notochord is sufficient for patterning of the intervertebral discs.

Science.gov (United States)

Choi, Kyung-Suk; Lee, Chanmi; Harfe, Brian D

2012-01-01

The intervertebral discs, located between adjacent vertebrae, are required for stability of the spine and distributing mechanical load throughout the vertebral column. All cell types located in the middle regions of the discs, called nuclei pulposi, are derived from the embryonic notochord. Recently, it was shown that the hedgehog signaling pathway plays an essential role during formation of nuclei pulposi. However, during the time that nuclei pulposi are forming, Shh is expressed in both the notochord and the nearby floor plate. To determine the source of SHH protein sufficient for formation of nuclei pulposi we removed Shh from either the floor plate or the notochord using tamoxifen-inducible Cre alleles. Removal of Shh from the floor plate resulted in phenotypically normal intervertebral discs, indicating that Shh expression in this tissue is not required for disc patterning. In addition, embryos that lacked Shh in the floor plate had normal vertebral columns, demonstrating that Shh expression in the notochord is sufficient for pattering the entire vertebral column. Removal of Shh from the notochord resulted in the absence of Shh in the floor plate, loss of intervertebral discs and vertebral structures. These data indicate that Shh expression in the notochord is sufficient for patterning of the intervertebral discs and the vertebral column. Copyright © 2012 Elsevier Ireland Ltd.

Kohl Malone, Susan; Ziporyn, Terra; Buttenheim, Alison M

2017-12-01

Healthy People 2020 established a national objective to increase the proportion of 9th-to-12th-grade students reporting sufficient sleep. A salient approach for achieving this objective is to delay middle and high school start times. Despite decades of research supporting the benefits of delayed school start times on adolescent sleep, health, and well-being, progress has been slow. Accelerating progress will require new approaches incorporating strategies that influence how school policy decisions are made. In this commentary, we introduce four strategies that influence decision-making processes and demonstrate how they can be applied to efforts aimed at changing school start time policies.

Newton-Krylov methods applied to nonequilibrium radiation diffusion

International Nuclear Information System (INIS)

Knoll, D.A.; Rider, W.J.; Olsen, G.L.

1998-01-01

The authors present results of applying a matrix-free Newton-Krylov method to a nonequilibrium radiation diffusion problem. Here, there is no use of operator splitting, and Newton's method is used to convert the nonlinearities within a time step. Since the nonlinear residual is formed, it is used to monitor convergence. It is demonstrated that a simple Picard-based linearization produces a sufficient preconditioning matrix for the Krylov method, thus elevating the need to form or store a Jacobian matrix for Newton's method. They discuss the possibility that the Newton-Krylov approach may allow larger time steps, without loss of accuracy, as compared to an operator split approach where nonlinearities are not converged within a time step

Applying Space Technology to Enhance Control of an Artificial Arm for Children and Adults With Amputations

Science.gov (United States)

Atkins, Diane J.

1998-01-01

The first single function myoelectric prosthetic hand was introduced in the 1960's. This hand was controlled by the electric fields generated by muscle contractions in the residual limb of the amputee user. Electrodes and amplifiers, embedded in the prosthetic socket, measured these electric fields across the skin, which increase in amplitude as the individual contracts their muscle. When the myoelectric signal reached a certain threshold amplitude, the control unit activated a motor which opened or closed a hand-like prosthetic terminal device with a pincher grip. Late in the 1990's, little has changed. Most current myoelectric prostheses still operate in this same, single-function way. To better understand the limitations of the current single-function myoelectric hand and the needs of those who use them, The Institute for Rehabilitation and Research (TIRR), sponsored by the National Institutes of Health (NUH), surveyed approximately 2,500 individuals with upper limb loss [1]. When asked to identify specific features of their current myoelectric prostheses that needed improvement, the survey respondents overwhelmingly identified the lack of wrist and finger movement, as well as poor control capability. However, simply building a mechanism with individual finger and wrist motion is not enough. In the 1960's and 1970's, engineers built a number of more dexterous prosthetic hands. Unfortunately, these were rejected during clinical trials due to a difficult and distracting control interface. The goal of this project, "Applying Space Technology to Enhance Control of an Artificial Arm for Children and Adults with Amputations," was to lay the foundation for a multi-function, intuitive myoelectric control system which requires no conscious thought to move the hand. We built an extensive myoelectric signal database for six motions from ten amputee volunteers, We also tested a control system based on new artificial intelligence techniques on the data from two of these

Cathelicidin is an important antimicrobial peptide in the urinary tract. Cathelicidin expression is strongly stimulated by 1,25-dihydroxy vitamin D in epithelial cells, macrophages/monocytes, and neutrophils. Vitamin D and cathelicidin status in children with urinary tract infection (UTI) caused by Escherichia coli is unknown. To establish the relationship between serum vitamin D and urine cathelicidin levels in children with a UTI caused by Escherichia coli. Serum 25-hydroxy vitamin D and urine cathelicidin levels were measured in 36 patients with UTI (mean age 6.8±3.6 years, range: 0.25-12.6 years) and 38 controls (mean age 6.3±2.8 years, range: 0.42-13 years). There were no significant differences in urine cathelicidin levels between the study and control groups (p>0.05). Eight (22.2%) patients in the study group and 21 (58.3%) children in the control group were found to have sufficient vitamin D (≥20 ng/mL). Patients with sufficient vitamin D had higher urine cathelicidin levels than the controls with sufficient vitamin D (respectively 262.5±41.1 vs. 168±31.6 ng/mL, p=0.001). There were no significant differences between the patients and controls with insufficient vitamin D (p>0.05). The children with vitamin D insufficiency may not be able to increase their urine cathelicidin level during UTI caused by Escherichia coli. There is a need of prospective studies in order to prove a beneficial effect of vitamin D supplementation for the restoration of cathelicidin stimulation and consequently for prevention of UTI recurrence.

Economic efficiency or self-sufficiency: alternative strategies for oil consumers?

International Nuclear Information System (INIS)

Heal, D.W.

1992-01-01

The ideal energy source is low cost (efficient) and reliable (secure). The high price and perceived political unreliability of Middle East oil supplies prompted a nearly worldwide trend towards energy self-sufficiency. Gains in energy efficiency, which have been most marked in the OECD, are permanent and, prompted by environmental concern, probably progressive. But the opportunity that is still available to low cost oil suppliers to regain lost markets will only be realized if those supplies are demonstrably reliable. (author)

Moral and cognitive development in retarded and nonretarded children.

Taylor, J J; Achenbach, T M

1975-07-01

Subjects were 30 cultural-familially retarded and 30 nonretarded children matched for MA within 3 MA levels. The subjects were administered measures of moral judgement and cognitive operations hypothesized by Kohlberg to constitute necessary but not sufficient conditions for attainment of specific moral stages. Moral and cognitive performance improved with MA, but there were no differences between the MA-matched retarded and nonretarded children. Moral judgement related more strongly to MA then to any of the specific cognitive operations tested. The findings failed to support Kohlberg and Gilligan's (1971) hypothesis that the moral judgment of older individuals should be more advanced than that of younger individuals matched for cognitive level, but they were in accord with Zigler's (1969) "developmental" concept of cultural-familial retardation.

The psychological model of thinking about money assumes that implicit reminders of money lead to self-sufficient motivation. Previous research has demonstrated that children react to money in similar ways to adults. The priming of young children with money related concepts or images has negatively affected their social behavior and social preferences, leading them to make more individualist and less pro-social choices and be less willing to help others. The aim of this research was to investi...

Criterion of independence applied to personnel responsible for in-house verification

International Nuclear Information System (INIS)

Pavaux, F.

1982-01-01

Framatome's experience has shown that one of the most difficult criteria to interpret in applying quality assurance programmes is that of ''organization''. In particular, this requires that personnel responsible for in-house verification should have ''sufficient independence''. The author examines how Framatome interprets the criterion of sufficient independence. It may seem easy to deal with this problem on paper, by redistributing the boxes of the organizational chart, but to do so is both unrealistic and deceptive; the development of reference models runs into difficulties when it comes to practical application and these difficulties alone justify trying another approach to the problem. The method advocated here consists in analysing each situation as it arises, taking into account the criterion in question, and disregarding any pre-defined model or reference situation. The analysis should involve all quality assurance functions and not, as is too often the case, only the independence of the quality assurance service. The analysis should also examine organizational freedom and independence from direct pressures of cost and schedule considerations. To support this recommendation, three standard cases are described (manufacturing control, design verification, on-site inspection team) which demonstrate how these criteria can give rise to different difficulties in different cases. The author concludes that, in contrast to other criteria so often applied by successive approximations, organizational changes should only be decided upon when absolutely necessary and after a detailed analysis of the particular case in question has been performed.

It is known that the largest developmental changes in the hippocampus take place during the prenatal period and during the first two years of postnatal life. Few studies have been conducted to address the normal developmental trajectory of the hippocampus during childhood. In this study shape analysis was applied to study the normal developing hippocampus in a group of 103 typically developing 6- to 10-year-old preadolescent children. The individual brain was normalized to a template, and then the hippocampus was manually segmented and further divided into the head, body, and tail sub-regions. Three different methods were applied for hippocampal shape analysis: radial distance mapping, surface-based template registration using the robust point matching (RPM) algorithm, and volume-based template registration using the Demons algorithm. All three methods show that the older children have bilateral expanded head segments compared to the younger children. The results analyzed based on radial distance to the centerline were consistent with those analyzed using template-based registration methods. In analyses stratified by sex, it was found that the age-associated anatomical changes were similar in boys and girls, but the age-association was strongest in girls. Total hippocampal volume and sub-regional volumes analyzed using manual segmentation did not show a significant age-association. Our results suggest that shape analysis is sensitive to detect sub-regional differences that are not revealed in volumetric analysis. The three methods presented in this study may be applied in future studies to investigate the normal developmental trajectory of the hippocampus in children. They may be further applied to detect early deviations from the normal developmental trajectory in young children for evaluating susceptibility for psychopathological disorders involving hippocampus.

2013-08-01

Full Text Available Fang-Yi Lin, Jiin-Ru Rong, Tzu-Ying Lee Department of Nursing, School of Nursing, National Taipei University of Nursing and Health Sciences, Taipei, Taiwan, Republic of China Abstract: The purpose of this concept analysis is to uncover the essential elements involved in caregivers' resilience in the context of caring for children with chronic conditions. Walker and Avant's methodology guided the analysis. The study includes a literature review of conceptual definitions of caregiver resilience in caring for children with chronic conditions. The defining attributes and correlates of caregiver resilience are reviewed. Concept analysis findings in a review of the nursing and health-related literature show that caregiver resilience in the context of caring for chronically ill children can be defined within four main dimensions, ie, disposition patterns, situational patterns, relational patterns, and cultural patterns. Empiric measurements of the impact of caregiver resilience applied to caregivers with children with chronic conditions are also reported in the analysis. The findings of this concept analysis could help nurses and health care providers to apply the concept of caregiver resilience in allied health care and be applied to further studies.

A step too far? Making health equity interventions in Namibia more sufficient

Ithindi Taati

2003-04-01

Full Text Available Abstract Background Equality of health status is the health equity goal being pursued in developed countries and advocated by development agencies such as WHO and The Rockefeller Foundation for developing countries also. Other concepts of fair distribution of health such as equity of access to medical care may not be sufficient to equalise health outcomes but, nevertheless, they may be more practical and effective in advancing health equity in developing countries. Methods A framework for relating health equity goals to development strategies allowing progressive redistribution of primary health care resources towards the more deprived communities is formulated. The framework is applied to the development of primary health care in post-independence Namibia. Results In Namibia health equity has been advanced through the progressive application of health equity goals of equal distribution of primary care resources per head, equality of access for equal met need and equality of utilisation for equal need. For practical and efficiency reasons it is unlikely that health equity would have been advanced further or more effectively by attempting to implement the goal of equality of health status. Conclusion The goal of equality of health status may not be appropriate in many developing country situations. A stepwise approach based on progressive redistribution of medical services and resources may be more appropriate. This conclusion challenges the views of health economists who emphasise the need to select a single health equality goal and of development agencies which stress that equality of health status is the most important dimension of health equity.

ParticipACTION's Think Again campaign targeted mothers who think their children are sufficiently active, yet whose children do not achieve recommended amounts of physical activity. This research examined the relationship of mothers' intentions to support children's physical activity with explicit believability and implicit agreement with the Think Again campaign message, attention paid to the advertisement, involvement with the issue, concern regarding children's inactivity, and attitudes. Participants were mothers from Edmonton, Canada (N = 102) who viewed one Think Again advertisement then completed a measure of implicit agreement with the campaign message and questionnaires. The mothers who paid attention to the message and were concerned for their own children were more likely to intend to act on campaign messages. The majority of participants implicitly agreed that children's physical inactivity was a problem, but there was less agreement that physical inactivity was a problem for their own children. Participants automatically tended to agree with campaign messages when the focus was on children in general, but there was greater disagreement when asked about participant's own children. Why most mothers were not in agreement with the reality of how much physical activity their children needs remains to be determined.

Influence of Hydrogen-Based Storage Systems on Self-Consumption and Self-Sufficiency of Residential Photovoltaic Systems

Directory of Open Access Journals (Sweden)

Christian Pötzinger

2015-08-01

Full Text Available This paper analyzes the behavior of residential solar-powered electrical energy storage systems. For this purpose, a simulation model based on MATLAB/Simulink is developed. Investigating both short-time and seasonal hydrogen-based storage systems, simulations on the basis of real weather data are processed on a timescale of 15 min for a consideration period of 3 years. A sensitivity analysis is conducted in order to identify the most important system parameters concerning the proportion of consumption and the degree of self-sufficiency. Therefore, the influences of storage capacity and of storage efficiencies are discussed. A short-time storage system can increase the proportion of consumption by up to 35 percentage points compared to a self-consumption system without storage. However, the seasonal storing system uses almost the entire energy produced by the photovoltaic (PV system (nearly 100% self-consumption. Thereby, the energy drawn from the grid can be reduced and a degree of self-sufficiency of about 90% is achieved. Based on these findings, some scenarios to reach self-sufficiency are analyzed. The results show that full self-sufficiency will be possible with a seasonal hydrogen-based storage system if PV area and initial storage level are appropriate.

Masoud Mahmoodzadeh

2013-12-01

Full Text Available In an endeavor to reflect on the advent of Applied ELT paradigm pioneered by Pishghadam (2011 in the area of second language education, this article delves into the unexplored nature of this emerging paradigm via a contemporary complexity-driven voice. The crux of the argument addressed in this article suggests that Applied ELT is a pragmatic manifestation of complex adaptive system of language teaching. To set the grounds expressly for such enquiry, firstly it draws on both premises and axioms associated with complexity theory and its existing literature in the circle of second language research. It then tracks down the evolutionary course of the new developed paradigm of Applied ELT within the realm of second language education and also elaborates the cornerstone and manifold tenets of this paradigm sufficiently. Finally, the article attempts to critically elucidate and rationalize the recent emergence of Applied ELT paradigm through the lens of complexity theory. To broaden our thinking and understanding about the potential and multi-directional influence of ELT field, the article ends by calling for a reshaped educational direction for ELT position in second language education.

Both children and adults are subject to similar types of injuries but fractures of facial bones in children are relatively uncommon. The aim of this study was to evaluate the epidemiology of facial bone fractures among children of fractures admitted over a span of 3 years. In order to compare our results we reviewed the existing literature related to pediatric facial bone fractures. A total of 45 children were admitted for facial bone fractures. Forty (89%) of them were above 5 years of age and male to female ratio was 2:1. About 53.33% of these injuries were because of fall from height. Mandible fracture was the most common facial bone fracture among admitted patients. Symphysis and para-symphysis was the commonest site of mandibular fractures, seen in 49% cases. Majority of these fractures were managed by Inter-maxillary fixation and inter-osseous wiring. Mini-plates were used for widely displaced compound fractures. For un-displaced fractures observation alone was sufficient. Mandible is the commonest facial bone fracture in children, more often caused by accidental fall from height. The high osteogenic potential of pediatric mandible allows non-surgical management to be successful in an increased proportion of younger patients.

Hypertension in children and adolescents: epidemiology and pathogenesis.

Science.gov (United States)

Raj, Manu; Krishnakumar, R

2013-03-01

High blood pressure is one among the leading contributors to burden of disease globally. Approximately 54 % of stroke and 47 % of ischemic heart disease events worldwide were attributable to high blood pressure in the year 2001. There is deficiency of data on the long-term outcome of hypertension in children. In spite of this, there is sufficient evidence to suspect that the health risks of hypertension in pediatric patients are substantial. Hypertension in childhood is known to result in hypertension in young adulthood. The epidemiology of hypertension in children is well represented from various studies conducted across continents. Factors like methodological issues in measurement, socio demographic differences, adiposity levels and ethnicity appear to influence the distribution of blood pressure as well as prevalence of hypertension in children. The etio-pathogenesis of essential (primary) hypertension is multi-factorial in origin. Obesity, insulin resistance, activation of sympathetic nervous system, alterations in sodium homeostasis, renin-angiotensin system changes, changes in vascular smooth muscle structure and reactivity, high serum uric acid levels, genetic factors and fetal programming have been reported to contribute to this disorder. The causes of secondary hypertension vary with age. Renal disorders and coarctation of the aorta are the most common causes of hypertension in children up to age 6 y. In older children, renal parenchymal disease remains the most frequent cause of increased blood pressure. Other causes of hypertension in children are relatively rare and include systemic arteritis and certain tumours, endocrine dysfunction, and neurologic disorders.

Behavioral Skills Training in Portuguese Children With School Failure Problems

Edgar Galindo

2018-05-01

Full Text Available This paper postulates that psychology can make an important contribution at an individual level to help children with school failure problems in a context where too little applied research has been conducted on the instructional needs of these children. Some data are analyzed, revealing that, despite some progress, school failure is still a main educational problem in many countries. In this study, Behavioral Skills Training (BST was applied in Portugal to train children with school failure difficulties. BST is a method based on Applied Behavior Analysis, a teaching package consisting of a combination of behavioral techniques: instructions, modeling, rehearsal, and feedback. Two empirical studies are presented. Their main purpose was to develop behavioral diagnostic and training techniques to teach lacking skills. School success was defined in terms of a set of skills proposed by teachers and school failure as a lack of one or more of these skills. The main instrument was a package of training programs to be applied in three areas: basic behavior (precurrents, academic behavior, or social behavior. The second instrument is a package of check-lists, aimed to determine the level of performance of the child in an area. This check-list was applied before (pre-test and after (post-test training. In the first study, 16, 7- to 8-year old children were trained. They were attending the second or third grades and having academic difficulties of different origins. The effects of the training programs are evaluated in terms of percentage of attained objectives, comparing a pre- and a post-test. The results showed an increase in correct responses after training in all cases. To provide a sounder demonstration of the efficacy of the training programs, a second study was carried out using a quasi-experimental design. A multiple baseline design was applied to three 10- to 11-year-old children, referred by teachers because of learning difficulties in the fourth

Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in children. In order to advance the field of NAFLD, noninvasive imaging methods for measuring liver fat are needed. Advanced magnetic resonance imaging (MRI) has shown great promise for the quantitative assessment of hepatic steatosis but has not been validated in children. Therefore, this study was designed to evaluate the correlation and diagnostic accuracy of MRI-estimated liver proton density fat fraction (PDFF), a biomarker for hepatic steatosis, compared to histologic steatosis grade in children. The study included 174 children with a mean age of 14.0 years. Liver PDFF estimated by MRI was significantly (P steatosis grade. The correlation of MRI-estimated liver PDFF and steatosis grade was influenced by both sex and fibrosis stage. The correlation was significantly (P steatosis and mild steatosis ranged from 0.69 to 0.82. The overall accuracy of predicting the histologic steatosis grade from MRI-estimated liver PDFF was 56%. No single threshold had sufficient sensitivity and specificity to be considered diagnostic for an individual child. Advanced magnitude-based MRI can be used to estimate liver PDFF in children, and those PDFF values correlate well with steatosis grade by liver histology. Thus, magnitude-based MRI has the potential for clinical utility in the evaluation of NAFLD, but at this time no single threshold value has sufficient accuracy to be considered diagnostic for an individual child. © 2015 by the American Association for the Study of Liver Diseases.

Nature exposure sufficiency and insufficiency: The benefits of environmental preservation.

Science.gov (United States)

Reddon, John R; Durante, Salvatore B

2018-01-01

Increasing industrialization, urbanization, and a failure of many world leaders to appreciate the consequences of climate change are deleteriously impacting quality of life as well as diminishing the prospects for long term survival. Economic competitiveness and corporate profitability often pre-empt environmental concerns. The calving of an iceberg in Antarctica and the hurricane activity in the Caribbean during 2017 are unfortunate illustrations of the continuing escalation of environmental issues. We provide historical and current evidence for the importance of Nature Exposure (NE) and introduce the continuum Nature Exposure Sufficiency (NES) and Insufficiency (NEI). Insufficiency includes impoverished environments (e.g., slums and prisons) where nature exposure is very limited. Nature Exposure Sufficiency (NES) is an optimal amount of exposure to nature where many benefits such as reinvigoration can be obtained by everyone. NES also has several benefits for individuals with various health conditions such as arthritis, dementia, or depression. The benefits of NE are not just derivable from parks, forests, and other natural settings. Interiors of buildings and homes can be enhanced with plants and even pictures or objects from nature. Additionally, there is abundant evidence indicating that virtual and artificial environments depicting nature can provide substantial NE and therefore contribute to general wellbeing. Besides the difficulty in achieving cooperation amongst nations, corporations, and other collectives in developing and implementing long range plans to deal with climate change, there is also sometimes an aversion at the individual level whereby people are unwilling to experience nature due to insects and other discomforts. Such individuals are often averse to supplanting the comforts of home, even temporarily, with inadequate facilities that are seemingly less pleasant than their typical dwellings. We propose using the term Nature Exposure Aversion

Artificial Self-Sufficient P450 in Reversed Micelles

Directory of Open Access Journals (Sweden)

Teruyuki Nagamune

2010-04-01

Full Text Available Cytochrome P450s are heme-containing monooxygenases that require electron transfer proteins for their catalytic activities. They prefer hydrophobic compounds as substrates and it is, therefore, desirable to perform their reactions in non-aqueous media. Reversed micelles can stably encapsulate proteins in nano-scaled water pools in organic solvents. However, in the reversed micellar system, when multiple proteins are involved in a reaction they can be separated into different micelles and it is then difficult to transfer electrons between proteins. We show here that an artificial self-sufficient cytochrome P450, which is an enzymatically crosslinked fusion protein composed of P450 and electron transfer proteins, showed micelle-size dependent catalytic activity in a reversed micellar system. Furthermore, the presence of thermostable alcohol dehydrogenase promoted the P450-catalyzed reaction due to cofactor regeneration.

Children with ADHD often present with handwriting difficulties. However, the extent to which motor and attention skills influence performance in this group has not yet been explored. The objective of this study was to examine the factors associated with change in handwriting performance. This study examines the factors associated with change in handwriting performance of 49 children newly diagnosed with ADHD (mean age = 8.4 [SD=1.3] years) prior to and 3 months following use of a stimulant medication. Handwriting legibility and speed improved significantly at follow-up evaluation. However, most of the children with legibility difficulties at baseline continued to demonstrate difficulties when evaluated 3 months after initiation of medication. Change in handwriting legibility was best determined by improvements in visual-motor integration skills (β = 0.07-0.10; p Handwriting difficulties are common in children with ADHD, and medication alone is not sufficient to resolve these challenges. © 2012 SAGE Publications.

Can children withhold consent to treatment?

Devereux, J A; Jones, D P; Dickenson, D L

1993-05-29

A dilemma exists when a doctor is faced with a child or young person who refuses medically indicated treatment. The Gillick case has been interpreted by many to mean that a child of sufficient age and intelligence could validly consent or refuse consent to treatment. Recent decisions of the Court of Appeal on a child's refusal of medical treatment have clouded the issue and undermined the spirit of the Gillick decision and the Children Act 1989. It is now the case that a child patient whose competence is in doubt will be found rational if he or she accepts the proposal to treat but may be found incompetent if he or she disagrees. Practitioners are alerted to the anomalies now exhibited by the law on the issue of children's consent and refusal. The impact of the decisions from the perspectives of medicine, ethics, and the law are examined. Practitioners should review each case of child care carefully and in cases of doubt seek legal advice.

Many countries have some kind of energy-system transformation either planned or ongoing for various reasons, such as to curb carbon emissions or to compensate for the phasing out of nuclear energy. One important component of these transformations is the overall reduction in energy demand. It is generally acknowledged that the domestic sector represents a large share of total energy consumption in many countries. Increased energy efficiency is one factor that reduces energy demand, but behavioral approaches (known as "sufficiency") and their respective interventions also play important roles. In this paper, we address citizens' heterogeneity regarding both their current behaviors and their willingness to realize their sufficiency potentials-that is, to reduce their energy consumption through behavioral change. We collaborated with three Swiss cities for this study. A survey conducted in the three cities yielded thematic sets of energy-consumption behavior that various groups of participants rated differently. Using this data, we identified four groups of participants with different patterns of both current behaviors and sufficiency potentials. The paper discusses intervention types and addresses citizens' heterogeneity and behaviors from a city-based perspective.

A necessary and sufficient condition for the occurrence of the quantum Zeno effect is given, refining a recent conjecture of Luo, Wang and Zhang. An analogous condition is derived for the quantum anti-Zeno effect. Both results rely on a formal connection between the quantum (anti-)Zeno effect and the weak law of large numbers

Full Text Available The main objective of this research is to present an alternative approach to meet beef self-sufficiency in West Papua, Indonesia. It mainly focuses on calculating the needed number of productive cows to enhance beef production in the province. Out of the total farmer households in Manokwari, Indonesia, 189 farmer-respondents were selected as samples of the study. Selection of the sample was based on the number of cattle kept in every age group (less than one (2 years old and the number of productive cows. Secondary data came from the time series data of the number of slaughtered cattle vis-à-vis the population of all districts in West Papua Province from 1980-2008. Data were analyzed using the Partial Adjustment Model (PAM and Ordinary Least Square (OLS method. Results of the study showed that beef self-sufficiency in West Papua depend on the availability of the number of productive cows to produce ready-slaughtered-bull in the previous year. Particularly for West Papua, to produce one unit of bull in the tth –year, with the assumption that cattle mortality is 4.92%, a number of 2.38 animal units AU of productive cows must be provided in the previous two (2 years.

Attended but unseen: visual attention is not sufficient for visual awareness.

Does any one psychological process give rise to visual awareness? One candidate is selective attention-when we attend to something it seems we always see it. But if attention can selectively enhance our response to an unseen stimulus then attention cannot be a sufficient precondition for awareness. Kentridge, Heywood & Weiskrantz [Kentridge, R. W., Heywood, C. A., & Weiskrantz, L. (1999). Attention without awareness in blindsight. Proceedings of the Royal Society of London, Series B, 266, 1805-1811; Kentridge, R. W., Heywood, C. A., & Weiskrantz, L. (2004). Spatial attention speeds discrimination without awareness in blindsight. Neuropsychologia, 42, 831-835.] demonstrated just such a dissociation in the blindsight subject GY. Here, we test whether the dissociation generalizes to the normal population. We presented observers with pairs of coloured discs, each masked by the subsequent presentation of a coloured annulus. The discs acted as primes, speeding discrimination of the colour of the annulus when they matched in colour and slowing it when they differed. We show that the location of attention modulated the size of this priming effect. However, the primes were rendered invisible by metacontrast-masking and remained unseen despite being attended. Visual attention could therefore facilitate processing of an invisible target and cannot, therefore, be a sufficient precondition for visual awareness.

This study aimed to determine the discriminative validity, reproducibility, and prevalence of clinical signs suggestive of pharyngeal dysphagia according to gross motor function in children with cerebral palsy (CP). It was a cross-sectional population-based study of 130 children diagnosed with CP at 18-36 months (mean=27.4, 81 males) and 40 children with typical development (TD, mean=26.2, 18 males). Sixteen signs suggestive of pharyngeal phase impairment were directly observed in a videoed mealtime by a speech pathologist, and reported by parents on a questionnaire. Gross motor function was classified using the Gross Motor Function Classification System. The study found that 67.7% of children had clinical signs, and this increased with poorer gross motor function (OR=1.7, pDysphagia cut-points were modified to exclude a single cough on fluids, with a modified prevalence estimate proposed as 50.8%. Clinical signs suggestive of pharyngeal dysphagia are common in children with CP, even those with ambulatory CP. Parent-report on 16 specific signs remains a feasible screening method. While coughing was consistently identified by clinicians, it may not reflect children's regular performance, and was not sufficiently discriminative in children aged 18-36 months.

Do Current German-Language Intelligence Tests Take into Consideration the Special Needs of Children with Disabilities? A review of 23 German intelligence test manuals shows that test-authors do not exclude the use of their tests for children with disabilities. However, these special groups play a minor role in the construction, standardization, and validation of intelligence tests. There is no sufficient discussion and reflection concerning the issue which construct-irrelevant requirements may reduce the validity of the test or which individual test-adaptations are allowed or recommended. Intelligence testing of children with disabilities needs more empirical evidence on objectivity, reliability, and validity of the assessment-procedures employed. Future test construction and validation should systematically analyze construct-irrelevant variance in item format, the special needs of handicapped children, and should give hints for useful test-adaptations.

How Do Families of Children with Down Syndrome Perceive Speech Intelligibility in Turkey?

2015-01-01

Full Text Available Childhood verbal apraxia has not been identified or treated sufficiently in children with Down syndrome but recent research has documented that symptoms of childhood verbal apraxia can be found in children with Down syndrome. But, it is not routinely diagnosed in this population. There is neither an assessment tool in Turkish nor any research on childhood verbal apraxia although there is a demand not only for children with Down syndrome but also for normally developing children. The study examined if it was possible to determine oral-motor difficulties and childhood verbal apraxia features in children with Down syndrome through a survey. The survey was a parental report measure. There were 329 surveys received. Results indicated that only 5.6% of children with Down syndrome were diagnosed with apraxia, even though many of the subject children displayed clinical features of childhood verbal apraxia. The most frequently reported symptoms of childhood verbal apraxia in literature were displayed by the children with Down syndrome in the study. Parents could identify childhood verbal apraxia symptoms using parent survey. This finding suggests that the survey can be developed that could serve as a screening tool for a possible childhood verbal apraxia diagnosis in Turkey.

Structural and functional perspectives on classification and seriation in psychotic and normal children.

Breslow, L; Cowan, P A

1984-02-01

This study describes a strategy for examining cognitive functioning in psychotic and normal children without the usual confounding effects of marked differences in cognitive structure that occur when children of the same age are compared. Participants were 14 psychotic children, 12 males and 2 females, mean age 9-2, matched with normal children at preoperational and concrete operational stage levels on a set of Piagetian classification tasks. The mean age of the normal children was 6-4, replicating the usually found developmental delay in psychotic samples. Participants were then compared on both structural level and functional abilities on a set of tasks involving seriation of sticks; the higher-level children were also administered a seriation drawing task. Analysis of children's processes of seriating and seriation drawings indicated that over and above the structural retardation, psychotic children at all levels showed functional deficits, especially in the use of anticipatory imagery. The implications for general developmental theory are that progress in structural development is not sufficient for imaginal development, and that structural development of logical concepts is relatively independent of the development of imagery. It was suggested that "thought disorder" may not be a disordered structure of thinking or a retardation in psychotic populations but rather a mismatch between higher-level logical structures and lower-level functions.

2011-08-01

Full Text Available Abstract Background Questionnaires used by health services to identify children with psychosocial problems are often rather short. The psychometric properties of such short questionnaires are mostly less than needed for an accurate distinction between children with and without problems. We aimed to assess whether a short Computerized Adaptive Test (CAT can overcome the weaknesses of short written questionnaires when identifying children with psychosocial problems. Method We used a Dutch national data set obtained from parents of children invited for a routine health examination by Preventive Child Healthcare with 205 items on behavioral and emotional problems (n = 2,041, response 84%. In a random subsample we determined which items met the requirements of an Item Response Theory (IRT model to a sufficient degree. Using those items, item parameters necessary for a CAT were calculated and a cut-off point was defined. In the remaining subsample we determined the validity and efficiency of a Computerized Adaptive Test using simulation techniques, with current treatment status and a clinical score on the Total Problem Scale (TPS of the Child Behavior Checklist as criteria. Results Out of 205 items available 190 sufficiently met the criteria of the underlying IRT model. For 90% of the children a score above or below cut-off point could be determined with 95% accuracy. The mean number of items needed to achieve this was 12. Sensitivity and specificity with the TPS as a criterion were 0.89 and 0.91, respectively. Conclusion An IRT-based CAT is a very promising option for the identification of psychosocial problems in children, as it can lead to an efficient, yet high-quality identification. The results of our simulation study need to be replicated in a real-life administration of this CAT.

The aim of the present study was to determine the user satisfaction of the EyeToy for the training of the upper limb in children with cerebral palsy (CP). User satisfaction was measured in 12 children with CP, using a postexperience questionnaire, primarily based on a presence questionnaire. In general, children with CP were satisfied with and motivated by the EyeToy training. In addition, a first evaluation study was performed to determine the effect of this training method on the upper limb function. Ten children with CP were randomly assigned to the intervention (mean age 11 years, 9 months; SD 2,3) and the control group (mean age 12 years, 3 months; SD 3,2). After a treatment period of 6 weeks, the intervention group completed a user satisfaction questionnaire. Functional outcome was measured using the Melbourne Assessment scores. Percentage scores of the Melbourne Assessment of 7 of the 10 children were the same or changed only 1% to 2% from baseline to followup. However, in the experimental group, two children improved more, 9% and 13% respectively. In conclusion, it can be said that the EyeToy is a motivational training tool for the training of children with CP and has the potential to improve upper extremity function.

Level of knowledge regarding oral hygiene among the parents of pre-school children plays an important role on maintaining the good oral hygiene of their children. In Nepal, sufficient research has not been carried out on this area. Objective of this study is to assess the level of knowledge on oral hygiene of preschool children's parents attending pediatric outpatient department in Dhulikhel Hospital. A descriptive study was conducted from November 2012 to January 2013 among one hundred parents of preschool children visiting pediatrics outpatient department of Dhulikhel Hospital. Paper and pencil based semi structured questionnaire was used for collecting data. Questions related to demographic information and knowledge were asked. Thirty questions were used for assessing knowledge level. Knowledge score was calculated by allocating one point for each correct answer and zero point for each wrong answer. Analyzed data were presented in terms of numbers and percentages. Total knowledge scores were categorized based on percentage. Knowledge score was categorized on four group - exclusive intervals - namely-poor (0-40%), moderate (40-60%), good (60-80%) and excellent (80-100%). Mann-Whitney U test and Kruskal-Wallis test were applied to check significance difference and chisquare test was used to check association among different background characteristic. It was found that 81% had moderate knowledge, 15% had poor knowledge and 4% had good knowledge about oral hygiene. Median knowledge score was found to be 15 with range 10 to 21. Following variables were found to be significant difference on knowledge category: Education status (poral health problem (p = 0.008), Further significant association was found between knowledge category and educational status (pknowledge category and past experience (pKnowledge regarding oral hygiene was found satisfactory among the parents of preschool children visiting pediatric OPD of Dhulikhel Hospital.

Putting Children's Sleep Problems to Bed: Using Behavior Change Theory to Increase the Success of Children's Sleep Education Programs and Contribute to Healthy Development.

Blunden, Sarah; Benveniste, Tessa; Thompson, Kirrilly

2016-07-01

Sleep is critical for the healthy development of children, yet most children simply don't get enough. Whilst school based sleep education programs have been developed for parents and their children, they have had mixed success. We consider how use of behavior change theory in existing school-based sleep education programs can be improved by applying and apply a broader model to these programs. We find that the mixed success of school-based sleep education programs may be due to a plausible but misleading assumption that simply increasing information about the importance of sleep and the risks of insufficient and/or inefficient sleep will necessarily result in improved sleep behaviors. We identify the potential benefits of using behavior change theory in the development of sleep education programs but in particular, there is a need for theories incorporate the multiple biological, environmental and social impacts on children's sleep. Bronfenbrenner's Bioecological model is presented to illustrate how one such behavior change theory could significantly improve the success of sleep education programs and ultimately support the healthy development of children.

Full Text Available The technique of behaviour management in medical treatment, especially in dental treatment, is needed to eliminate uncooperative children behaviour. The main factor influencing children behaviour is fear of painful that usually related to dental treatment. Children patients who will have their post­labioplasty and palatoplasty stitches removed have more sensitive condition, they cry when the dentist gives treatment. Using general anesthesia is a method to manage uncooperative children behaviour. Inhalational anesthesia is often used in general anesthesia and sevoflurane is a drug of choice. Sevoflurane has low solubility in blood, pleasant odor, nonirritating airway, and has a rapid induction of and recovery from anesthesia. Some researches indicate that sevoflurane gives more calm condition and can be used as a sufficiently ideal induction and maintenance of anesthesia in children. Sevoflurane can therefore made as alternative procedure in the removal of post-labioplasty and palatoplasty stitches.

Brandão, Daniela Filipa Soares; Martín, José Ignacio

2012-06-01

The Montessori method was initially applied to children, but now it has also been applied to people with dementia. The purpose of this study is to systematically review the research on the effectiveness of this method using Medical Literature Analysis and Retrieval System Online (Medline) with the keywords dementia and Montessori method. We selected lo studies, in which there were significant improvements in participation and constructive engagement, and reduction of negative affects and passive engagement. Nevertheless, systematic reviews about this non-pharmacological intervention in dementia rate this method as weak in terms of effectiveness. This apparent discrepancy can be explained because the Montessori method may have, in fact, a small influence on dimensions such as behavioral problems, or because there is no research about this method with high levels of control, such as the presence of several control groups or a double-blind study.

Children and their 4-H animal projects: How children use science in agricultural activity

Science.gov (United States)

Emo, Kenneth Roy

Many children are introduced to science through informal educational programs. 4-H, an educational youth program, has a history of introducing scientific practices into agriculture. The purpose of this ethnographically-driven case study is to examine how science informs the actions of children raising market animals in a 4-H project. For two years the researcher collected data on 4-H children with market animal projects. Observations, interviews, and artifacts gathered are interpreted using the framework of activity theory. This study provides evidence for how the context of an activity system influences individual actions. Rules developed by the organization guide the actions of children to incorporate physical and psychological tools of science into their project to achieve the object: producing animals of proper weight and quality to be competitive in the county fair. Children learn the necessary actions from a community of practitioners through which expertise is distributed. Children's learning is demonstrated by the way their participation in their project changes with time, from receiving assistance from others to developing expertise in which they provide assistance to others. The strength of this educational experience is how children apply specific tools of science in ways that provide meaning and relevancy to their 4-H activity.

We analyzed 62 cases of thyroid cancer in children and adolescents of Bryansk and Kaluga regions, the most contaminated as a result of the Chernobyl accident. The data on specified radiation situation as well as probable radiation doses to the thyroid are given. It is noted that the development of thyroid cancer depends on the age of children at the time of accident (0-3, 7-9, 12-15 years). They are the most critical periods for the formation and functioning of the thyroid, in particular, in girls. It is suggested that thyroid cancer develops in children and teenagers residing in areas with higher Cs 137 contamination level at younger age than in those residing in less contaminated regions. It is shown that the minimal latent period in the development of thyroid cancer makes up to 5 years. The results of ESR method on tooth enamel specimen indicate that over post-accident period the sufficient share of children has collected such individual radiation dose which are able to affect on their health state and development of thyroid pathology

In construction of a new nuclear power plant, carbon steel and stainless steel are used as base materials for the bottom linear plate of Reinforced Concrete Containment Vessel (RCCV) to achieve maintenance-free requirement, securing sufficient strength of structure. However, welding such different metals is difficult by ordinary method. To overcome the difficulty, the automated Magnetic Stirring Welding (MSW) method that can demonstrate good welding performance was studied for practical use, and weldability tests showed the good results. Based on the study, a new welding device for the MSW method was developed to apply it weld joints of different materials, and it practically used in part of a nuclear power plant. (author)

Cultural responses to pain in UK children of primary school age: a mixed-methods study.

Azize, Pary M; Endacott, Ruth; Cattani, Allegra; Humphreys, Ann

2014-06-01

Pain-measurement tools are often criticized for not addressing the influence of culture and ethnicity on pain. This study examined how children who speak English as a primary or additional language discuss pain. Two methods were used in six focus group interviews with 34 children aged 4-7 years: (i) use of drawings from the Pediatric Pain Inventory to capture the language used by children to describe pain; and (ii) observation of the children's placing of pain drawings on red/amber/green paper to denote perceived severity of pain. The findings demonstrated that children with English as an additional language used less elaborate language when talking about pain, but tended to talk about the pictures prior to deciding where they should be placed. For these children, there was a positive significant relationship between language, age, and length of stay in the UK. The children's placement of pain drawings varied according to language background, sex, and age. The findings emphasize the need for sufficient time to assess pain adequately in children who do not speak English as a first language. © 2013 Wiley Publishing Asia Pty Ltd.

Age-independent variability in childrens' napping duration may be influenced by parental preference and attitudes and childrens' availability or lack of opportunity to nap. Our study examined English preschool childrens' napping duration, frequency and location, and the association of daily nap duration with parents' attitudes towards napping. Parents of three-year-old children in deprived and nondeprived areas of a town in North-East England were interviewed regarding their attitudes towards child napping and completed four-day and five night sleep diaries documenting their childrens' daytime and nighttime sleep. Of 84 children, half had at least one nap during the four-day study period (median [interquartile range] daily nap duration across all children was 1 [21] min; for nappers only was 21 [34] min). Naps tended to be infrequent and short and few (6%) occurred in a bedroom. Children whose parents allowed or encouraged napping had significantly longer daily nap duration (n=25, median [interquartile range] daily nap duration 21 [34] min) compared to those whose parents tried to prevent them from napping (n=29, 1 [21] min), and those whose parents reported that children did not want to nap (n=30, 0 [0] min) (U=23.21; pnapping was associated with longer child nap duration. Napping appeared to be mainly sporadic and opportunistic and was negatively perceived and prevented by one-third of parents. The consequences of premature nap cessation are not known; given the importance of sufficient sleep in childhood, we should possibly consider enabling young children to nap more freely.

Pieper, Barbara; Templin, Thomas N

2015-04-01

Adequate nutrition has long been considered a critical component for wound healing, but literature regarding the relationship between nutrition and venous ulcer (VU) healing is limited. A person's nutrition is affected by the availability of food as well as his/her overall health. Food sufficiency and nutrition are important concerns in the care of persons of low income with injection-related VUs, which tend to be large and slow to heal. A cross-sectional pilot study was conducted to explore the relationship between food sufficiency/security and nutrition with regard to demographic, wound, quality-of-life, physical activity, falls, and fall risk variables. Nutrition was examined using 2 well-developed instruments that measure food sufficiency/security and assess nutrition--the United States Department of Agriculture's Adult Food Sufficiency Questionnaire (FSQ) and the Nestle Mini Nutritional Assessment (MNA). All participants (N = 31, 54% men, mean age 56.1 ± 3.6 years, all African American) were recruited from an outpatient clinic. All had injection-related VUs from a history of injecting illicit substances. In terms of food sufficiency/security, most participants (26, 84%) reported having enough food in the house, but 10 (32%) worried about running out of food. From 16% to 22.6% of participants expressed concern with food sufficiency/security in terms of cutting meal size, eating less, hunger, and weight loss. Food sufficiency/security was high for 19 (61.3%), but 12 (39%) had marginal or lower food sufficiency/security. MNA scores showed 16 participants (52%) were at risk of malnutrition or malnourished. Low food sufficiency/security was significantly (P nutrition assessment scores were significantly associated (P nutrition assessment are important to assess in low-income persons with injection-related VUs. A number of significant relationships of the FSQ and MNA to other variables was found but needs further investigation with a larger sample.

Introduction The issue of street children is one of the global social problems rising in low- and middle-income countries. These children are vulnerable, but because of a lack of sufficient information, it is very difficult for stakeholders to address their plight in Cameroon. Aim To examine the situation and characteristics of street children in three Cameroonian cities. Objectives To describe the demographic, socio-economic and behavioural profiles of street children. To identify challenges of street children and to compare the results from the three cities on account of their different settings, cultural history and challenges. Materials and methods The study was an analytical cross-sectional survey conducted through researcher-administered questionnaires to 399 street children (homeless for at least a month), in three Cameroonian cities from 1 January 2015 to 30 March 2015. Results The majority of the participants were boys, more than 70% were homeless for less than 12 months and poverty was found to be the most common reason for being on the street. Most of the participants earned less than 500CFA francs (USD 0.85), with many of them resorting to begging, drug abuse, sex work and other risky behaviours. Only two of the respondents (0.5%) regarded the public attitude towards them as supportive. Conclusion As children roam the streets in search of shelter, food and other basic needs, their future hangs in the balance. Understanding the plight of street children highlights the need for immediate design and implementation of intervention strategies to prevent children from living in the streets and assist those who have become street children.

The aim of the study was to investigate the prevalance of enterically transmitted hepatitis among children living in post-earthquake camps, and to assess the efficacy of the measurements during and after the disaster in Duezce and Golyaka. In the second half of 1999, North-western Turkey, was struck by two massive earthquakes in less than 3months. The first, on 17 August 1999, involving Golyaka, was struck, measuring between 7.4 and 7.8 on the Richter scale. Irregularity about providing clean water and necessary sanitary facilities were observed after the first earthquake because of confusion. The second quake, on 12 November 1999, which rated 7.2 on the Richter scale, shook Duezce. Necessary precautions were applied rapidly at the second quake about shelter, clean drinking water, food and control of distribution of the aids by government and civil aid organisations. Anti-HEV(IgG) and anti-HAV(IgG) antibodies were determined in 476 sera of the children who was living in six camps. HAV prevalence of the children who were living in Duezce and Golyaka temporary houses was 44.4 and 68.8% respectively, OR: 0.37, CI 95%: 0.22-0.61, p=0.0005. HEV prevalence of the children was 4.7 and 17.2% respectively, OR: 0.24, CI 95%: 0.11-0.51, p=0.0007. In conclusion, HAV and HEV prevalence of children were lower than that in endemic areas but higher than that in developed countries. This study has pointed out the importance of providing urgent need of the sufficient sanitary facilities after disasters for preventing or reducing the incidence of enterically transmitted hepatitis, especially in the regions which were at risk for various disasters. Essential precautions such as providing clean water and food supply must be taken and an emergency action plan for preventing the infectious disease must be prepared before disasters such as earthquakes

Childhood injuries constitute a major public health problem worldwide. First aid is an effective life-preservation tool at work, school, home, and in public locations. In this study, the effectiveness of a first-aid program delivered by undergraduate nursing students to preparatory school children was examined. This quasi-experimental study was carried out on 100 school children in governmental preparatory schools in Egypt. The researchers designed a program for first-aid training, and this was implemented by trained nursing students. The evaluation involved immediate post-test and follow-up assessment after two months. The results showed generally low levels of satisfactory knowledge and inadequate situational practice among the school students before the intervention. Statistically-significant improvements were shown at the post- and follow-up tests. Multivariate regression analysis identified the intervention and the type of school as the independent predictors of the change in students' knowledge score, while the intervention and the knowledge score were the predictors of the practice score. The study concluded that a first-aid training program delivered by nursing students to preparatory school children is effective in improving their knowledge and practice. © 2013 Wiley Publishing Asia Pty Ltd.

2012-10-01

Full Text Available Upon examination of eleven main buildings of power plants, analysis of defects and damages of building structures was performed. Thereafter, the damageability of principal bearing structures of main buildings of thermal plants was analyzed. It was identified that the fastest growing defects and damages were concentrated in the structures of operating sites. The research of the rate of development of the most frequent damages and defects made it possible to conclude that internal corrosion of the reinforcing steel was the most dangerous defect, as far as the reinforced concrete elements of operating sites were concerned. Methods of mathematical statistics were applied to identify the reinforcing steel development pattern inside reinforced concrete elements of floors of operating sites. It was identified that the probability of corrosion of reinforced concrete elements of operating sites was distributed in accordance with the demonstrative law. Based on these data, calculation of strength of reinforced concrete slabs and metal beams was performed in terms of their regular sections, given the natural loads and the realistic condition of structures. As a result, dependence between the bearing capacity reserve ratio and the corrosion development pattern was identified for reinforced concrete slabs and metal beams of operating sites. In order to analyze the sufficiency of the bearing capacity of building structures of operating sites in relation to their time in commission, equations were derived to identify the nature of dependence between the sufficiency of the bearing capacity of reinforced concrete slabs and metal beams of the operating sites and their time in commission.

Regret and adaptive decision making in young children.

2015-07-01

In line with the claim that regret plays a role in decision making, O'Connor, McCormack, and Feeney (Child Development, 85 (2014) 1995-2010) found that children who reported feeling sadder on discovering they had made a non-optimal choice were more likely to make a different choice the next time around. We examined two issues of interpretation regarding this finding: whether the emotion measured was indeed regret and whether it was the experience of this emotion, rather than the ability to anticipate it, that affected decision making. To address the first issue, we varied the degree to which children aged 6 or 7 years were responsible for an outcome, assuming that responsibility is a necessary condition for regret. The second issue was addressed by examining whether children could accurately anticipate that they would feel worse on discovering they had made a non-optimal choice. Children were more likely to feel sad if they were responsible for the outcome; however, even if they were not responsible, children were more likely than chance to report feeling sadder. Moreover, across all conditions, feeling sadder was associated with making a better subsequent choice. In a separate task, we demonstrated that children of this age cannot accurately anticipate feeling sadder on discovering that they had not made the best choice. These findings suggest that although children may feel regret following a non-optimal choice, even if they were not responsible for an outcome, they may experience another negative emotion such as frustration. Experiencing either of these emotions seems to be sufficient to support better decision making. Copyright © 2015 The Authors. Published by Elsevier Inc. All rights reserved.

Mating motives are neither necessary nor sufficient to create the beauty premium.

Hafenbrädl, Sebastian; Dana, Jason

2017-01-01

Mating motives lead decision makers to favor attractive people, but this favoritism is not sufficient to create a beauty premium in competitive settings. Further, economic approaches to discrimination, when correctly characterized, could neatly accommodate the experimental and field evidence of a beauty premium. Connecting labor economics and evolutionary psychology is laudable, but mating motives do not explain the beauty premium.

An energy self-sufficient public building using integrated renewable sources and hydrogen storage

Marino, C.; Nucara, A.; Pietrafesa, M.; Pudano, A.

2013-01-01

The control of the use of fossil fuels, major cause of greenhouse gas emissions and climate changes, in present days represents one of Governments' main challenges; particularly, a significant energy consumption is observed in buildings and might be significantly reduced through sustainable design, increased energy efficiency and use of renewable sources. At the moment, the widespread use of renewable energy in buildings is limited by its intrinsic discontinuity: consequently integration of plants with energy storage systems could represent an efficient solution to the problem. Within this frame, hydrogen has shown to be particularly fit in order to be used as an energetic carrier. In this aim, in the paper an energetic, economic and environmental analysis of two different configurations of a self-sufficient system for energy production from renewable sources in buildings is presented. In particular, in the first configuration energy production is carried out by means of photovoltaic systems, whereas in the second one a combination of photovoltaic panels and wind generators is used. In both configurations, hydrogen is used as an energy carrier, in order to store energy, and fuel cells guarantee its energetic reconversion. The analysis carried out shows that, although dimensioned as a stand-alone configuration, the system can today be realized only taking advantage from the incentivizing fares applied to grid-connected systems, that are likely to be suspended in the next future. In such case, it represents an interesting investment, with capital returns in about 15 years. As concerns economic sustainability, in fact, the analysis shows that the cost of the energy unit stored in hydrogen volumes, due to the not very high efficiency of the process, presently results greater than that of directly used one. Moreover, also the starting fund of the system proves to be very high, showing an additional cost with respect to systems lacking of energy storage equal to about 50

TGF-β Signaling Is Necessary and Sufficient for Pharyngeal Arch Artery Angioblast Formation

Directory of Open Access Journals (Sweden)

Maryline Abrial

2017-07-01

Full Text Available The pharyngeal arch arteries (PAAs are transient embryonic blood vessels that mature into critical segments of the aortic arch and its branches. Although defects in PAA development cause life-threating congenital cardiovascular defects, the molecular mechanisms that orchestrate PAA morphogenesis remain unclear. Through small-molecule screening in zebrafish, we identified TGF-β signaling as indispensable for PAA development. Specifically, chemical inhibition of the TGF-β type I receptor ALK5 impairs PAA development because nkx2.5+ PAA progenitor cells fail to differentiate into tie1+ angioblasts. Consistent with this observation, we documented a burst of ALK5-mediated Smad3 phosphorylation within PAA progenitors that foreshadows angioblast emergence. Remarkably, premature induction of TGF-β receptor activity stimulates precocious angioblast differentiation, thereby demonstrating the sufficiency of this pathway for initiating the PAA progenitor to angioblast transition. More broadly, these data uncover TGF-β as a rare signaling pathway that is necessary and sufficient for angioblast lineage commitment.

The present study aimed to investigate the relationship between meningocele and tethered cord syndrome, diagnosis of meningocele associated with tethered cord syndrome, and when to perform surgery and the best surgical procedure. Sixty-nine children with meningocele who were admitted to Shanghai Children's Medical Center were analyzed. The relationship between meningocele and other lesions causing tethered cord syndrome was studied by combining magnetic resonance imaging (MRI) and intraoperative findings. The MRI results and intraoperative findings showed that 67 children (97%) had associated lesions such as tight filum terminale, fibrous band tethering, spinal cord or cauda equina adhesion, diastematomyelia, arachnoid cyst, and epidermoid cyst. The protruded meninges were repaired, and the intraspinal lesions were treated at the same time. Also, the tethered spinal cord was released. No neurological injuries were observed after surgery. The rate of meningocele associated with tethered cord syndrome is very high. MRI is necessary for the diagnosis of meningocele. Active surgical treatment is recommended immediately after definite diagnosis. During surgery, the surgeon should not only repair the protruded meninges but also explore the spinal canal and release the tethered cord.

2007-09-01

Carl Rogers' article (see record 2007-14639-002) on the necessary and sufficient conditions for personality change has had a significant impact on the field of psychotherapy and psychotherapy research. He emphasized the client as arbiter of his or her own subjective experience and tested his hypothesized therapist-offered conditions of change using recorded sessions. This aided in demystifying the therapeutic process and led to a radical shift in the listening stance of the therapist. I briefly outline my views regarding the influence of the ideas presented in this work, describe the intellectual and cultural context of the times, and discuss a number of ways in which the therapist-offered conditions for psychological transformation are neither necessary nor sufficient.

Arterial stiffening provides sufficient explanation for primary hypertension.

Directory of Open Access Journals (Sweden)

Klas H Pettersen

2014-05-01

Full Text Available Hypertension is one of the most common age-related chronic disorders, and by predisposing individuals for heart failure, stroke, and kidney disease, it is a major source of morbidity and mortality. Its etiology remains enigmatic despite intense research efforts over many decades. By use of empirically well-constrained computer models describing the coupled function of the baroreceptor reflex and mechanics of the circulatory system, we demonstrate quantitatively that arterial stiffening seems sufficient to explain age-related emergence of hypertension. Specifically, the empirically observed chronic changes in pulse pressure with age and the impaired capacity of hypertensive individuals to regulate short-term changes in blood pressure arise as emergent properties of the integrated system. The results are consistent with available experimental data from chemical and surgical manipulation of the cardio-vascular system. In contrast to widely held opinions, the results suggest that primary hypertension can be attributed to a mechanogenic etiology without challenging current conceptions of renal and sympathetic nervous system function.

Necessary and sufficient liveness condition of GS3PR Petri nets

Liu, GaiYun; Barkaoui, Kamel

2015-05-01

Structural analysis is one of the most important and efficient methods to investigate the behaviour of Petri nets. Liveness is a significant behavioural property of Petri nets. Siphons, as structural objects of a Petri net, are closely related to its liveness. Many deadlock control policies for flexible manufacturing systems (FMS) modelled by Petri nets are implemented via siphon control. Most of the existing methods design liveness-enforcing supervisors by adding control places for siphons based on their controllability conditions. To compute a liveness-enforcing supervisor with as much as permissive behaviour, it is both theoretically and practically significant to find an exact controllability condition for siphons. However, the existing conditions, max, max‧, and max″-controllability of siphons are all overly restrictive and generally sufficient only. This paper develops a new condition called max*-controllability of the siphons in generalised systems of simple sequential processes with resources (GS3PR), which are a net subclass that can model many real-world automated manufacturing systems. We show that a GS3PR is live if all its strict minimal siphons (SMS) are max*-controlled. Compared with the existing conditions, i.e., max-, max‧-, and max″-controllability of siphons, max*-controllability of the SMS is not only sufficient but also necessary. An example is used to illustrate the proposed method.

Little is known about the mental workload, or psychological costs, associated with information processing tasks in children. We adapted the highly regarded NASA Task Load Index (NASA-TLX) multidimensional workload scale (Hart & Staveland, 1988) to test its efficacy for use with elementary school children. We developed 2 types of tasks, each with 2 levels of demand, to draw differentially on resources from the separate subscales of workload. In Experiment 1, our participants were both typical and school-labeled gifted children recruited from 4th and 5th grades. Results revealed that task type elicited different workload profiles, and task demand directly affected the children's experience of workload. In general, gifted children experienced less workload than typical children. Objective response time and accuracy measures provide evidence for the criterion validity of the workload ratings. In Experiment 2, we applied the same method with 1st- and 2nd-grade children. Findings from Experiment 2 paralleled those of Experiment 1 and support the use of NASA-TLX with even the youngest elementary school children. These findings contribute to the fledgling field of educational ergonomics and attest to the innovative application of workload research. Such research may optimize instructional techniques and identify children at risk for experiencing overload.

Full Text Available In children, intensive near-work affects the accommodation system of the eye. Younger children, due to anatomical parameters, read at smaller distance than older children and we can expect that the accommodation system of younger can be affected more than that of older children. We wanted to test this hypothesis. Some authors showed that the norms of amplitude of accommodation (AA developed by Hofstetter (1950 not always could be applied for children. We also wanted to verify these results. A total of 106 (age 7-15 children participated in the study. Distance visual acuity was measured for all children and only data of children with good visual acuity 1.0 or more (dec. units were analysed (73 children. Accommodative amplitude was measured before and after lessons using subjective push-up technique (with RAF Near Point Ruler. The results showed that the amplitude of accommodation reduced significantly (p < 0.05 during the day and decrease of AA was similar in different age groups (about ~0.70 D. Additional measurements are needed to verify that the observed changes in AA were associated with fatigue effect. The results showed lower accommodation values compared to average values calculated according to the Hofstetter equation (p < 0.05.

Design of fuel cell powered data centers for sufficient reliability and availability

It is challenging to design a sufficiently reliable fuel cell electrical system for use in data centers, which require 99.9999% uptime. Such a system could lower emissions and increase data center efficiency, but the reliability and availability of such a system must be analyzed and understood. Currently, extensive backup equipment is used to ensure electricity availability. The proposed design alternative uses multiple fuel cell systems each supporting a small number of servers to eliminate backup power equipment provided the fuel cell design has sufficient reliability and availability. Potential system designs are explored for the entire data center and for individual fuel cells. Reliability block diagram analysis of the fuel cell systems was accomplished to understand the reliability of the systems without repair or redundant technologies. From this analysis, it was apparent that redundant components would be necessary. A program was written in MATLAB to show that the desired system reliability could be achieved by a combination of parallel components, regardless of the number of additional components needed. Having shown that the desired reliability was achievable through some combination of components, a dynamic programming analysis was undertaken to assess the ideal allocation of parallel components.

Fuel self-sufficient and low proliferation risk multi-recycling of spent fuel

Cho, N. Z.; Hong, S. G.; Kim, T. H.; Greenspan, E.; Kastenberg, W. E.

1998-01-01

A preliminary feasibility study has been performed in search of promising nuclear energy systems which could make efficient use of the spent fuel from LWRs and be proliferation resistant. The energy considered consist of a dry process and a fuel-self-sufficient reactor which are synergistic. D 2 O, H 2 O and Pb (or Pb-Bi) are considered for the coolant. The most promising identified consists of Pb-cooled reactors with either an AIROX or an IFR-like reprocessing. H 2 O- (possibly mixed with D 2 O) cooled reactors can be designed to be fuel-self-sufficient and multi-recycle LWR spent fuel, provided they are accelerator driven. Moderator-free, D 2 O-cooled critical reactors can multi-recycle Th- 233 U fuel using IFR-type reprocessing; they are significantly more attractive than their thermal counterparts. H 2 O- (possibly mixed with D 2 O) cooled, accelerator-driven reactors appear attractive for converting Th into denatured 233 U using LWR spent fuel and the IFR process. The CANDU reactor technology appears highly synergistic with accelerator-driven systems. (author). 25 refs., 3 tabs., 6 figs

Aim. To develop and validate a questionnaire for detecting atopic dermatitis in infants and small children from the age of 2 months. Methods. Parents to 60 children answered a written questionnaire prior to a physical examination and individual semistructured interview. Qualitative and quantitative analyses of validity, sensitivity, specificity, and predictive values of the questionnaire were performed. Results. A total of 27 girls and 33 boys, aged 2 to 71 months, 35 with and 25 without physician-diagnosed eczema, participated. Validation of the questionnaire by comparisons with physicians' diagnoses showed a sensitivity of 0.91 (95% CI 0.77–0.98) and a specificity of 1 (95% CI 0.86–1). Conclusions. Three questions in a parental questionnaire were sufficient for diagnosing eczema in infants and small children. PMID:22500189

An investigation was made of applying combined laser therapy in the treatment of 619 children (422 children constituted the experimental group and 197 children composed the control group) affected by inherited forms of psychoverbal retardation. It was found that low-intensity He-Ne laser radiation with the wavelength of 632.8 nm and the output power of 2 mW made it possible to improve the children's mental development. Moreover, it effectively increased their mental activities, such as speech, communication, arbitrary behavior regulation, and locomotory functions. Laser therapy applied in treating children affected by the arrested mental development aggravated by obesity additionally decreased their body weight, increased their field of vision, and eliminated dyslipidemia. It was also found that contraindications to He-Ne laser acupuncture included phenylketonuria-related noncorrected metabolic defects, convulsive syndromes, epileptic activities, convulsive readiness, and cerebrolysine intramuscular injections.

Full Text Available Glucose-6-phosphate dehydrogenase (G6PD deficiency is the most common human enzymopathy and in Sub-Saharan Africa, is a significant cause of infection- and drug-induced hemolysis and neonatal jaundice. Our goals were to determine the prevalence of G6PD deficiency among Nigerian children of different ethnic backgrounds and to identify predictors of G6PD deficiency by analyzing vital signs and hematocrit and by asking screening questions about symptoms of hemolysis. We studied 1,122 children (561 males and 561 females aged 1 month to 15 years. The mean age was 7.4 ± 3.2 years. Children of Yoruba ethnicity made up the largest group (77.5% followed by those Igbo descent (10.6% and those of Igede (10.2% and Tiv (1.8% ethnicity. G6PD status was determined using the fluorescent spot method. We found that the overall prevalence of G6PD deficiency was 15.3% (24.1% in males, 6.6% in females. Yoruba children had a higher prevalence (16.9% than Igede (10.5%, Igbo (10.1% and Tiv (5.0% children. The odds of G6PD deficiency were 0.38 times as high in Igbo children compared to Yoruba children (p=0.0500. The odds for Igede and Tiv children were not significantly different from Yoruba children (p=0.7528 and 0.9789 respectively. Mean oxygen saturation, heart rate and hematocrit were not significantly different in G6PD deficient and G6PD sufficient children. The odds of being G6PD deficient were 2.1 times higher in children with scleral icterus than those without (p=0.0351. In conclusion, we determined the prevalence of G6PD deficiency in Nigerian sub-populations. The odds of G6PD deficiency were decreased in Igbo children compared to Yoruba children. There was no association between vital parameters or hematocrit and G6PD deficiency. We found that a history of scleral icterus may increase the odds of G6PD deficiency, but we did not exclude other common causes of icterus such as sickle cell disease or malarial infection.

Auditory and Visual Attention Performance in Children With ADHD: The Attentional Deficiency of ADHD Is Modality Specific.

2017-08-01

This study explored auditory and visual attention in children with ADHD. In a randomized, two-period crossover design, 50 children with ADHD and 50 age- and sex-matched typically developing peers were measured with the Test of Various Attention (TOVA). The deficiency of visual attention is more serious than that of auditory attention in children with ADHD. On the auditory modality, only the deficit of attentional inconsistency is sufficient to explain most cases of ADHD; however, most of the children with ADHD suffered from deficits of sustained attention, response inhibition, and attentional inconsistency on the visual modality. Our results also showed that the deficit of attentional inconsistency is the most important indicator in diagnosing and intervening in ADHD when both auditory and visual modalities are considered. The findings provide strong evidence that the deficits of auditory attention are different from those of visual attention in children with ADHD.

PULSE WAVE VELOCITY AND CENTRAL AORTIC PRESSURE IN OBESE CHILDREN ACCORDING TO THE NON-INVASIVE ARTERIOGRAPHY RESULTS

Directory of Open Access Journals (Sweden)

O. V. Kozhevnikova

2013-01-01

Full Text Available The article presents information value of non-invasive arteriography, which reveals early signs of cardiovascular pathology formation in children, using a large number of trials in children. The authors examined predictors of cardiovascular catastrophes’ development, confirmed in adults: aortic wall’s stiffness, central aortic pressure and pulse pressure – that have not been sufficiently studied in children yet. The article shows that the high-technology method of non-invasive arteriography allows revealing changes of these parameters in children on the preclinical stage. It also shows their correlation with body mass index, fatty hepatosis, direct correlation of weight gain with connection of pulse wave velocity and central blood pressure and importance of follow-up evaluation of these parameters. Heterogeneity of the group of obese children in terms of these parameters is a premise for development of individual approach to control and prevention of cardiovascular complications’ development risk in childhood.

Children's pain perspectives.

Esteve, R; Marquina-Aponte, V

2012-05-01

Previous studies on children's pain perspectives remain limited to English-speaking populations. An exploratory cross-sectional descriptive design was used to investigate the developmental progression of children's pain perspectives, including their pain experience, its definition and attributes, causality and coping. The Children's Pain Perspectives Inventory was applied to 180 healthy Spanish children. A coding system was developed following the content analysis method. Three age groups were compared: 4-6 years, corresponding to the Piagetian pre-operational stage of cognitive development; 7-11 years, corresponding to stage of concrete operations; and 12-14 years, corresponding to the period of early formal operations. In children between 4 and 6, the predominant narratives related to physical injuries, the notion of causality and the definition of pain. In children between 7 and 11, the predominant narratives were those in which pain was described as a sensation in one part of the body. The view of pain as having an emotional basis significantly increased with age and was more frequent in adolescents. In contrast, children between 4-6 and 7-11 indicated that pain occurs spontaneously. The denial of any positive aspects of pain significantly decreased with age; some children between 7 and 11 referred to the 'possibility of relief', while the view that pain is a 'learning experience' was significantly more frequent among adolescents aged between 12 and 14 years. The use of cognitive strategies to control pain significantly increased with age. Between 12 and 14 years of age, adolescents communicate pain by non-verbal behaviour and reported that they do not express demands for relief. There was a progression from concrete to more complex notions of pain as age increased. These results may be of use to health professionals and parents to understand how children at various developmental stages express and cope with pain and to develop tools that effectively assess and

Applying industrial engineering practices to radiology.

Seven hospitals in Oregon and Washington have successfully adopted the Toyota Production System (TPS). Developed by Taiichi Ohno, TPS focuses on finding efficiencies and cost savings in manufacturing processes. A similar effort has occurred in Canada, where Toronto's Hospital for Sick Children has developed a database for its diagnostic imaging department built on the principles of TPS applied to patient encounters. Developed over the last 5 years, the database currently manages all interventional patient procedures for quality assurance, inventory, equipment, and labor. By applying industrial engineering methodology to manufacturing processes, it is possible to manage these constraints, eliminate the obstacles to achieving streamlined processes, and keep the cost of delivering products and services under control. Industrial engineering methodology has encouraged all stakeholders in manufacturing plants to become participants in dealing with constraints. It has empowered those on the shop floor as well as management to become partners in the change process. Using a manufacturing process model to organize patient procedures enables imaging department and imaging centers to generate reports that can help them understand utilization of labor, materials, equipment, and rooms. Administrators can determine the cost of individual procedures as well as the total and average cost of specific procedure types. When Toronto's Hospital for Sick Children first implemented industrial engineering methodology to medical imaging interventional radiology patient encounters, it focused on materials management. Early in the process, the return on investment became apparent as the department improved its management of more than 500,000 dollars of inventory. The calculated accumulated savings over 4 years for 10,000 interventional procedures alone amounted to more than 140,000 dollars. The medical imaging department in this hospital is only now beginning to apply what it has learned to

The performance of 40 children with complicated mild to severe traumatic brain injury on the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV; Wechsler, 2003) was compared with that of 40 demographically matched healthy controls. Of the four WISC-IV factor index scores, only Processing Speed yielded a statistically significant group difference (p < .001) as well as a statistically significant negative correlation with length of coma (p < .01). Logistic regression, using Processing Speed to classify individual children, yielded a sensitivity of 72.50% and a specificity of 62.50%, with false positive and false negative rates both exceeding 30%. We conclude that Processing Speed has acceptable criterion validity in the evaluation of children with complicated mild to severe traumatic brain injury but that the WISC-IV should be supplemented with other measures to assure sufficient accuracy in the diagnostic process.

Full Text Available One of the foundational gestures of the disability rights movement was the rejection of the common description of people who live with physical or mental impairments as "eternal children." This paper argues that the contradictions inherent in applying this trope to adults amplify the contradictions inherent in applying it to children themselves. From its heyday in in the 19th-century "Golden Age" of children's literature to its afterlife in 20th-century disabling rhetoric, the fantasy of childhood as stasis requires denying the fact of growth.

Renal ultrasound and excretory urography in infants and young children with urinary tract infection

International Nuclear Information System (INIS)

Kenda, R.; Kenig, T.; Silc, M.; Zupancic, Z.

1989-01-01

The main purpose of the study was to see whether excretory urography (EU) can be safely replaced by ultrasound (US) in children with urinary tract infection (UTI) younger than 6 years. 101 hospitalised children were admitted to the prospective study. They were all diagnosed as having UTI and were treated accordingly. All children had voiding cystography (VCU), EU and US done. US and EU correlated well in 94% of the cases. In all 6 cases with discrepancy between EU and US, the VCU was abnormal. Our results confirm the data from other authors, that VCU and US should be sufficient as an initial work-up on children with UTI, while EU should be done only in the cases with abnormal findings on either one or both of the former investigations. However, it should be kept in mind that some cases of parenchymal involvement or mild subpelvic stenosis can be missed using this protocol. If EU is obtained only in the cases with abnormal US and/or VCU, only 55 children (54%) in our group would have had an EU done. (orig.)

The sufficiency assumption of the reasoned approach to action

Directory of Open Access Journals (Sweden)

David Trafimow

2015-12-01

Full Text Available The reasoned action approach to understanding and predicting behavior includes the sufficiency assumption. Although variables not included in the theory may influence behavior, these variables work through the variables in the theory. Once the reasoned action variables are included in an analysis, the inclusion of other variables will not increase the variance accounted for in behavioral intentions or behavior. Reasoned action researchers are very concerned with testing if new variables account for variance (or how much traditional variables account for variance, to see whether they are important, in general or with respect to specific behaviors under investigation. But this approach tacitly assumes that accounting for variance is highly relevant to understanding the production of variance, which is what really is at issue. Based on the variance law, I question this assumption.

Retrocausal Effects as a Consequence of Quantum Mechanics Refined to Accommodate the Principle of Sufficient Reason

Energy Technology Data Exchange (ETDEWEB)

Stapp, Henry P.

2011-05-10

The principle of sufficient reason asserts that anything that happens does so for a reason: no definite state of affairs can come into being unless there is a sufficient reason why that particular thing should happen. This principle is usually attributed to Leibniz, although the first recorded Western philosopher to use it was Anaximander of Miletus. The demand that nature be rational, in the sense that it be compatible with the principle of sufficient reason, conflicts with a basic feature of contemporary orthodox physical theory, namely the notion that nature's response to the probing action of an observer is determined by pure chance, and hence on the basis of absolutely no reason at all. This appeal to pure chance can be deemed to have no rational fundamental place in reason-based Western science. It is argued here, on the basis of the other basic principles of quantum physics, that in a world that conforms to the principle of sufficient reason, the usual quantum statistical rules will naturally emerge at the pragmatic level, in cases where the reason behind nature's choice of response is unknown, but that the usual statistics can become biased in an empirically manifest way when the reason for the choice is empirically identifiable. It is shown here that if the statistical laws of quantum mechanics were to be biased in this way then the basically forward-in-time unfolding of empirical reality described by orthodox quantum mechanics would generate the appearances of backward-time-effects of the kind that have been reported in the scientific literature.

Maximizing Health or Sufficient Capability in Economic Evaluation? A Methodological Experiment of Treatment for Drug Addiction.

Science.gov (United States)

Goranitis, Ilias; Coast, Joanna; Day, Ed; Copello, Alex; Freemantle, Nick; Frew, Emma

2017-07-01

Conventional practice within the United Kingdom and beyond is to conduct economic evaluations with "health" as evaluative space and "health maximization" as the decision-making rule. However, there is increasing recognition that this evaluative framework may not always be appropriate, and this is particularly the case within public health and social care contexts. This article presents a methodological case study designed to explore the impact of changing the evaluative space within an economic evaluation from health to capability well-being and the decision-making rule from health maximization to the maximization of sufficient capability. Capability well-being is an evaluative space grounded on Amartya Sen's capability approach and assesses well-being based on individuals' ability to do and be the things they value in life. Sufficient capability is an egalitarian approach to decision making that aims to ensure everyone in society achieves a normatively sufficient level of capability well-being. The case study is treatment for drug addiction, and the cost-effectiveness of 2 psychological interventions relative to usual care is assessed using data from a pilot trial. Analyses are undertaken from a health care and a government perspective. For the purpose of the study, quality-adjusted life years (measured using the EQ-5D-5L) and years of full capability equivalent and years of sufficient capability equivalent (both measured using the ICECAP-A [ICEpop CAPability measure for Adults]) are estimated. The study concludes that different evaluative spaces and decision-making rules have the potential to offer opposing treatment recommendations. The implications for policy makers are discussed.

A Sufficient Condition on Convex Relaxation of AC Optimal Power Flow in Distribution Networks

DEFF Research Database (Denmark)

Huang, Shaojun; Wu, Qiuwei; Wang, Jianhui

2016-01-01

This paper proposes a sufficient condition for the convex relaxation of AC Optimal Power Flow (OPF) in radial distribution networks as a second order cone program (SOCP) to be exact. The condition requires that the allowed reverse power flow is only reactive or active, or none. Under the proposed...... solution of the SOCP can be converted to an optimal solution of the original AC OPF. The efficacy of the convex relaxation to solve the AC OPF is demonstrated by case studies of an optimal multi-period planning problem of electric vehicles (EVs) in distribution networks....... sufficient condition, the feasible sub-injection region (power injections of nodes excluding the root node) of the AC OPF is convex. The exactness of the convex relaxation under the proposed condition is proved through constructing a group of monotonic series with limits, which ensures that the optimal...

Unaccompanied and Separated Foreign Children in the Care System in the Western Cape – A Socio-Legal Study

Julia Sloth-Nielsen

2016-05-01

Full Text Available This article reports on the findings of a study of foreign children accommodated in the care system in the Western Cape, based on fieldwork conducted in child and youth care centres. The objectives of the study were firstly to map and quantify the number and demographics of foreign children placed in all CYCCs across the Western Cape. Secondly, the study aimed to analyse the reasons for children's migration and the circumstances around their placement in residential care institutions in order to establish whether family reunification was possible or desirable. Thirdly, the study explores the sufficiency of efforts made to trace and reunify the children with their families, whether in South Africa or across borders, as the institutional placement of children should not only be a last resort but it should preferably be temporary whilst family-based solutions are sought. Lastly, the documentation status of the children in the study was examined. Recommendations emanating from the research conclude the study.

2017-09-01

To determine the effect of the Early Start Denver Model (ESDM) for treatment of young children with autism on health care service use and costs. We used data from a randomized trial that tested the efficacy of the ESDM, which is based on developmental and applied behavioral analytic principles and delivered by trained therapists and parents, for 2 years. Parents were interviewed about their children's service use every 6 months from the onset of the intervention to follow-up (age 6 years). The sample for this study consisted of 39 children with autism who participated in the original randomized trial at age 18 to 30 months, and were also assessed at age 6 years. Of this sample, 21 children were in the ESDM group, and 18 children were in the community care (COM) group. Reported services were categorized and costed by applying unit hourly costs. Annualized service use and costs during the intervention and post intervention for the two study arms were compared. During the intervention, children who received the ESDM had average annualized total health-related costs that were higher by about $14,000 than those of children who received community-based treatment. The higher cost of ESDM was partially offset during the intervention period because children in the ESDM group used less applied behavior analysis (ABA)/early intensive behavioral intervention (EIBI) and speech therapy services than children in the comparison group. In the postintervention period, compared with children who had earlier received treatment as usual in community settings, children in the ESDM group used less ABA/EIBI, occupational/physical therapy, and speech therapy services, resulting in significant cost savings in the amount of about $19,000 per year per child. Costs associated with ESDM treatment were fully offset within a few years after the intervention because of reductions in other service use and associated costs.

Effects of Classroom Bilingualism on Task Shifting, Verbal Memory, and Word Learning in Children

Kaushanskaya, Margarita; Gross, Megan; Buac, Milijana

2014-01-01

We examined the effects of classroom bilingual experience in children on an array of cognitive skills. Monolingual English-speaking children were compared with children who spoke English as the native language and who had been exposed to Spanish in the context of dual-immersion schooling for an average of two years. The groups were compared on a measure of non-linguistic task-shifting; measures of verbal short-term and working memory; and measures of word-learning. The two groups of children did not differ on measures of non-linguistic task-shifting and verbal short-term memory. However, the classroom-exposure bilingual group outperformed the monolingual group on the measure of verbal working memory and a measure of word-learning. Together, these findings indicate that while exposure to a second language in a classroom setting may not be sufficient to engender changes in cognitive control, it can facilitate verbal memory and verbal learning.

2014-06-01

Helminth infections and micronutrient deficiencies are highly prevalent in developing countries. Neither condition typically causes overt disease, but they do lead to indirect morbidity such as impaired physical and cognitive development. We aimed to systematically review current evidence on the relation of helminth infections with micronutrient status in school-age children worldwide. We included both observational studies and randomized controlled trials (RCTs). We applied a random-effects meta-analysis to estimate 1) cross-sectional associations between helminths and micronutrient status, 2) effects of anthelminthic treatment on micronutrient status, and 3) effects of micronutrient supplementation on helminth infection and reinfection. Meta-analyses of observational studies showed an association between helminth infections and serum retinol [standardized mean difference (SMD): -0.30; 95% CI: -0.48, -0.13] but not serum ferritin (SMD: 0.00; 95% CI: -0.7, 0.7). Conversely, meta-analyses of anthelminthic treatment RCTs showed a positive effect on ferritin (SMD: 0.16; 95% CI: 0.09, 0.22) but not retinol (SMD: 0.04; 95% CI: -0.06, 0.14). The number of studies on micronutrients other than ferritin and retinol was not sufficient for pooling. Meta-analyses of micronutrient-supplementation RCTs showed only a modest protective effect for multimicronutrient interventions on helminth infection and reinfection rates (OR: 0.77; 95% CI: 0.61, 0.97). In this review, we show evidence of distinct associations between helminth infections and micronutrients in school-age children. More studies are needed on micronutrients other than iron and vitamin A and on possible helminth species-specific effects. A thorough comprehension of the interplay between helminth infections and micronutrients will help guide integrated and sustainable intervention strategies in affected children worldwide. © 2014 American Society for Nutrition.

Maternal obesity and vitamin D sufficiency are associated with cord blood vitamin D insufficiency.

An inverse relationship between total serum 25-hydroxyvitamin D (25-OH D) and increased adiposity has been established in children, adolescents, and adults. However, the relationship between neonatal adiposity and vitamin D status has not been reported. Both maternal obesity and vitamin D deficiency in pregnancy are common and are associated with adverse pregnancy outcomes. The aim of the study was to determine the relationship between vitamin D levels in mothers and newborns, as influenced by maternal obesity, and evaluate these associations with neonatal adiposity. Sixty-one maternal-neonatal pairs participated in this cross-sectional study at an academic medical center. Mothers had a prepregnancy body mass index that was normal or obese. Maternal and cord blood sera were assayed for 25-OH D, and neonatal body composition was measured by air displacement plethysmography. Mothers had similar and sufficient levels of 25-OH D when measured at 36-38 wk gestation, irrespective of body mass index category (normal weight, 46.05, vs. obese, 49.84 ng/ml; P = not significant). However, cord blood 25-OH D was higher in neonates of normal-weight mothers compared to neonates of obese mothers (27.45 vs. 20.81 ng/ml; P = 0.02). The variance in cord blood 25-OH D was explained by four factors: maternal 25-OH D level, the presence of maternal obesity, maternal age, and neonatal adiposity (r(2) = 0.66). Obese women transfer less 25-OH D to offspring than normal-weight women, despite similar serum levels. Cord blood 25-OH D levels directly correlate to neonatal percentage body fat. These novel findings underscore the evolving relationships between maternal obesity, vitamin D nutritional status, and adiposity in the neonatal period that may influence subsequent childhood and adulthood vitamin D-dependent processes.

Universal salt iodisation (USI) has been successfully implemented in China for more than 15 years. Recent evidence suggests that the definition of 'adequate iodine' (100-199 µg/l) be revised to 'sufficient iodine' (100-299 µg/l) based on the median urinary iodine concentration (MUI) in school-age children. The objective of this study was to determine the prevalence of thyroid dysfunction in populations after long-term salt iodisation and examine whether the definition of adequate iodine can be broadened to sufficient iodine based on the thyroid function in four population groups. A cross-sectional survey was conducted in six provinces in the northern, central and southern regions of China. Four population groups consisting of 657 children, 755 adults, 347 pregnant women and 348 lactating women were recruited. Three spot urinary samples were collected over a 10-d period and blood samples were collected on the 1st day. In the study, among the adults, pregnant women and lactating women, the prevalence rates of elevated thyroglobulin antibody and thyroid microsomal antibody levels were 12·4, 8·5 and 7·8 %, and 12·1, 9·1 and 9·1 %, respectively. Abnormally high thyroid dysfunction prevalence was not observed after more than 15 years of USI in China because the thyroid dysfunction rates were all <5 %. The recommended range should be cautiously broadened from adequate iodine to sufficient iodine according to the MUI of school-age children considering the high levels of hormones and antibodies in the other populations. Adults, particularly pregnant women positive for thyroid antibodies, should be closely monitored.

Progress and remaining difficulties in the construction of predictive mathematical models of large bodies of water as ecosystems are reviewed. Surface temperature is at present the only variable than can be measured accurately and reliably by remote sensing techniques, but satellite infrared data are of sufficient resolution for macro-scale modeling of oceans and large lakes, and airborne radiometers are useful in meso-scale analysis (of lakes, bays, and thermal plumes). Finite-element and finite-difference techniques applied to the solution of relevant coupled time-dependent nonlinear partial differential equations are compared, and the specific problem of the Biscayne Bay and environs ecosystem is tackled in a finite-differences treatment using the rigid-lid model and a rigid-line grid system.

A sufficiency property arising from the characterization of extremes of Markov chains

OpenAIRE

Bortot, Paola; Coles, Stuart

2000-01-01

At extreme levels, it is known that for a particular choice of marginal distribution, transitions of a Markov chain behave like a random walk. For a broad class of Markov chains, we give a characterization for the step length density of the limiting random walk, which leads to an interesting sufficiency property. This representation also leads us to propose a new technique for kernel density estimation for this class of models.

Full Text Available BACKGROUND The aim of the study was to determine the frequency of vitamin D deficiency and insufficiency in children with thalassaemia who were on regular blood transfusion. MATERIALS AND METHODS Total 25 children were included in this retrospective study in the age group of 2-14 years with confirmed diagnosis of thalassaemia syndrome. They were on regular blood transfusion every 3-4 weeks and they had serum ferritin >1000 µg/L irrespective of chelation therapy. Serum level of calcium, phosphorous, alkaline phosphatase, serum ferritin and 25OH vitamin D were estimated. RESULTS Out of 25 patients, 6 (24% showed sufficient amount of vitamin D, 6 (24% showed insufficiency, 10 (40% showed deficiency and 3 (12% showed severe deficiency. Children with vitamin D deficiency showed high level of serum ferritin level. Severe vitamin D deficiency was seen when number of transfusions were >20.14 children showed abnormal vitamin D level when their serum ferritin level was between 1000-2000 ng/dL. There was no association between use of iron-chelating agent, duration of their use and nutritional status with vitamin D level. CONCLUSION In regularly transfused thalassaemic children, vitamin D insufficiency and deficiency were common and they need frequent monitoring for early detection and management.

Virtual water trade is often considered a solution for restricted water availability in many regions of the world. Brazil is the world leader in the production and export of various agricultural and livestock products. The country is either a strong net importer or a strong net exporter of these products. The objective of this study is to determine the volume of virtual water contained in agricultural and livestock products imported/exported by Brazil from 1997 to 2012, and to define the water self-sufficiency index of agricultural and livestock products in Brazil. The indexes of water scarcity (WSI), water dependency (WDI) and water self-sufficiency (WSSI) were calculated for each Brazilian state. These indexes and the virtual water balance were calculated following the methodology developed by Chapagain and Hoekstra (2008) and Hoekstra and Hung (2005). The total water exports and imports embedded in agricultural and livestock products were 5.28 × 10 10 and 1.22 × 10 10  Gm 3  yr -1 , respectively, which results in positive virtual water balance of 4.05 × 10 10  Gm 3  yr -1 . Brazil is either a strong net importer or a strong net exporter of agricultural and livestock products among the Mercosur countries. Brazil has a positive virtual water balance of 1.85 × 10 10  Gm 3  yr -1 . The indexes used in this study reveal that Brazil is self-sufficient in food production, except for a few products such as wheat and rice. Horticultural products (tomato, onion, potato, cassava and garlic) make up a unique product group with negative virtual water balance in Brazil. Copyright © 2016 Elsevier Ltd. All rights reserved.

Peripheral facial nerve palsy (Bell' palsy, BP) is a not rare diseases in children, being the most common acquired mononeuropathy. The authors of this study wanted to determine whether the occurrence and course of paralysis changed in the past 5 years (2010-2014). The study involved Lesser Poland region, where the majority of children with paralysis are hospitalized at the Pediatric Neurology Department of University Children's Hospital in Krakow. These children in subsequent years were admitted to our department without any limitations. A review of clinical documentation of 125 patients, in terms of demographics, the coexistence of other diseases, seasonality, the degree of paralysis, location of paralysis, the prevalence of the recurrence was made. Changes in the structure of the nerve VII in MRI and CT, pharmacological treatment, applied rehabilitation, the degree of improvement and time of hospitalization were analyzed. Similar distribution of occurrence and gender of children with BP in Lesser Poland region within 5 years were observed. The predominance of the girls resulted from demographic composition of the population. BP occurred most frequently in summer and winter. In more than half of children BP occurred in the course of acute systemic infection or craniofacial infection and in 5/125 BP followed head injury. Children with infections required antibiotic therapy. Left-sided paralysis was found in the majority of children and almost half of patients needed protection of the cornea of the eye (significant degree). In 12% of children structural changes within the facial nerve were found. In these children antiviral treatment was used and hospitalization time was more than 20 days while in the majority of children hospitalization lasted 15 days. In 8 (6.4%) children with recurrent BP kinezytherapy, electrical stimulation and laser therapy were applied. Steroid therapy was not used. Only 7/125 chil. dren had mild impairment of the eye closing at the discharge

The North American Guidelines for Children's Agricultural Tasks (NAGCAT) were developed to assist parents in assigning developmentally appropriate and safe farm work to their children aged 7-16 years. Since their release in 1999, a growing body of evidence has accumulated regarding the content and application of these guidelines to populations of working children on farms. The purpose of this paper is to review the scientific and programmatic evidence about the content, efficacy, application, and uptake of NAGCAT and propose key recommendations for the future. The methods for this review included a synthesis of the peer-reviewed literature and programmatic evidence gathered from safety professionals. From the review, it is clear that the NAGCAT tractor guidelines and the manual material handling guidelines need to be updated based upon the latest empirical evidence. While NAGCAT do have the potential to prevent serious injuries to working children in the correct age range (7-16 years), the highest incidence of farm related injuries and fatalities occur to children aged 1-6 years and NAGCAT are unlikely to have any direct effect on this leading injury problem. It is also clear that NAGCAT, as a voluntary educational strategy, is not sufficient by itself to protect children working on farms. Uptake of NAGCAT has been sporadic, despite being geographically widespread and has depended, almost solely, on a few interested and committed professionals. Key recommendations for the future are provided based upon this review.

Constructive interaction provides natural thinking-aloud as test subjects collaborate in pairs to solve tasks. Since children may face difficulties in following instructions for a standard think-aloud test, constructive interaction has been suggested as evaluation method when usability testing...... with children. However, the relationship between think-aloud and constructive interaction is still poorly understood. We present an experiment that compares think-aloud and constructive interaction in usability testing. The experiment involves 60 children with three setups where children apply think......-aloud, and constructive interaction in acquainted and non-acquainted pairs. Our results show that the pairing of children had impact on how the children collaborated in pairs and how they would afterward assess the testing sessions. In some cases, we found that acquainted dyads would perform well as they would more...

Osteocalcin is necessary and sufficient to maintain muscle mass in older mice

Full Text Available Objective: A decrease in muscle protein turnover and therefore in muscle mass is a hallmark of aging. Because the circulating levels of the bone-derived hormone osteocalcin decline steeply during aging in mice, monkeys and humans we asked here whether this hormone might regulate muscle mass as mice age. Methods: We examined muscle mass and strength in mice lacking osteocalcin (Ocn−/− or its receptor in all cells (Gprc6a−/− or specifically in myofibers (Gprc6aMck−/− as well as in 9 month-old WT mice receiving exogenous osteocalcin for 28 days. We also examined protein synthesis in WT and Gprc6a−/− mouse myotubes treated with osteocalcin. Results: We show that osteocalcin signaling in myofibers is necessary to maintain muscle mass in older mice in part because it promotes protein synthesis in myotubes without affecting protein breakdown. We further show that treatment with exogenous osteocalcin for 28 days is sufficient to increase muscle mass of 9-month-old WT mice. Conclusion: This study uncovers that osteocalcin is necessary and sufficient to prevent age-related muscle loss in mice.

To estimate the serum levels of vitamin D in children with growing pains and determine the relationship between serum vitamin D levels, parathormone and routine biochemical markers. Study Design: Cross-sectional study. Place and Duration of Study: Department of Paediatrics, Liaquat National Hospital, Karachi, from October 2008 to September 2009. Methodology: Hundred children, aged 5-12 years presenting in Paediatric Outpatient Department of Liaquat National Hospital, Karachi, with limb pains, fulfilling the diagnostic criteria of growing pains, were included. Children with any systemic illness, organic cause of pain, rheumatologic disorders and signs of rickets were excluded from the study. Children were investigated for serum total calcium, inorganic phosphorus, alkaline phosphatase, vitamin D3 (25-hydroxycholecalciferol) and parathormone levels. On the basis of serum vitamin D3 level, patients were divided into 3 groups; group 1 with normal level of vitamin D3 (> 75 nmol/L), group 2 with vitamin D insufficiency (level between 50-75 nmol/L), and group 3 with vitamin D deficiency (level < 50 nmol/L). Significance of group proportions was determined using chi-square test with significance at p < 0.05. Results: The mean age of the participants was 8.05 years with the majority (59%) being females. Only 6% had normal vitamin D levels. Over 95% of the children with vitamin D insufficiency had normal alkaline phosphatase and parathormone levels. Conclusion: Hypovitaminosis D may have a role in pathogenesis of growing pains. All children with unexplained limb pains without identifiable organic pathology should be tested for vitamin D status, and treated, if necessary. Routine biochemical markers alone are not sufficient to detect all cases of hypovitaminosis D. (author)

Pediatricians recommend daily sleep of at least ten hours for children aged 9 and 10 years. Sufficient sleep is necessary for maintaining the body's homeostasis, as well as for fixing memories and learning. Lack of sleep in children has been associated with a diminished school performance, reduced attention span, and obesity. Adulthood is influenced by childhood lifestyle habits. Data from 4th graders in 34 schools in Mainz and its surroundings were analysed in order to determine negative health lifestyle factors in German primary school children, such as lack of sleep and increased leisure time spent watching television and computer gaming. Data from a cross-sectional study regarding cellular phone use in fourth-graders in Mainz were used for this analysis. Bedtime, television and computer use habits, as well as other factors were explored. A total of 1933 children from 34 schools participated by answering a questionnaire in the 2002-2003 school year (participation rate: 88%). Complete data for the secondary analysis were available from 1889 students (51% male, median age 10 years). Overall, 28% of the children reported going to bed after 9 pm on week nights, 16% reported watching television more than three hours daily, and 11% played computer or video games more than three hours daily. In the adjusted binary logistic regression model, being older, male, having older siblings, watching television (OR 1.82, 95% CI 1.28-2.61) and playing computer games (OR 3.23; 95% CI 2.24-4.67) for more than three hours daily, owning a mobile phone, and being in a school in the city were associated with going to bed after 9 pm. Every fourth child does not obtain a sleep duration of 10 hours, under the assumption that primary schoolchildren need to be awake at 7 am on weekdays. Lifestyle factors that may negatively influence a child's development determine their actual and future habits. Sufficient sleep and less television and computer leisure times should be assertively

Guidelines for the Review of Environmental-Related Legislation Regarding the Realisation of the Right to Access to Sufficient Food

Full Text Available The development of legislation for the progressive realisation of the right to access to sufficient food is labelled as an international and national objective. Section 27(2 of the Constitution of the Republic of South Africa, 1996 assigns a compulsory mandate to the South African government to take reasonable legislative and other measures, within its available resources, to achieve the progressive realisation of the right to access to sufficient food. The United Nations' Food and Agricultural Organization (FAO proposes a three-level strategy for the implementation of the right to food on a national legislative level, namely through: constitutional recognition, the implementation of a food framework law and the reviewing of relevant sectoral legislation. This contribution focuses on the last level of legislative provisioning, namely the reviewing of relevant sectoral legislation which influences, or possibly can, influence the realisation of the right to access to sufficient food. The right to access to sufficient food has multidimensional, interdisciplinary and cross-sectoral characteristics and consequently various sectors are involved in the realisation of the right to access to sufficient food. The FAO determines that the intended purpose will be to identify and review all sectoral legislation that might influence the availability, stability, access and adequacy of food, by means of a proposed reviewing process. The suggested reviewing process of the FAO is comprehensive and diverse; therefore the focus of this contribution is based on the reviewing of relevant environmental-related legislation only. The FAO does not make recommendations with regard to the specific aspects that need to be incorporated in environmental-related legislation to contribute to the progressive realisation of the right to access to sufficient food (in other words the aspects against which environmental-related legislation can be evaluated. Therefore this

Few children eat sufficient fruits and vegetables despite their established health benefits. The feeding practices used by parents when introducing novel foods to their children, and their efficacy, require further investigation. We aimed to establish which feeding strategies parents commonly use when introducing a novel fruit to their preschool-aged children and assess the effectiveness of these feeding strategies on children's willingness to try a novel fruit. Correlational design. Twenty-five parents and their children aged 2 to 4 years attended our laboratory and consumed a standardized lunch, including a novel fruit. Interactions between parent and child were recorded and coded. Pearson's correlations and multiple linear regression analyses. The frequency with which children swallowed and enjoyed the novel fruit, and the frequency of taste exposures to the novel fruit during the meal, were positively correlated with parental use of physical prompting and rewarding/bargaining. Earlier introduction of solids was related to higher frequency of child acceptance behaviors. The child's age at introduction of solids and the number of physical prompts displayed by parents significantly predicted the frequency of swallowing and enjoying the novel fruit. Age of introduction to solids and parental use of rewards/bargaining significantly predicted the frequency of taste exposures. Prompting a child to eat and using rewards or bargains during a positive mealtime interaction can help to overcome barriers to novel fruit consumption. Early introduction of solids is also associated with greater willingness to consume a novel fruit. Copyright © 2012 Academy of Nutrition and Dietetics. Published by Elsevier Inc.

Full Text Available Receptive vocabulary develops rapidly in early childhood and builds the foundation for language acquisition and literacy. Variation in receptive vocabulary ability is associated with variation in children's school achievement, and low receptive vocabulary ability is a risk factor for under-achievement at school. In this study, bivariate and multivariate growth curve modelling was used to estimate trajectories of receptive vocabulary development in relation to a wide range of candidate child, maternal and family level influences on receptive vocabulary development from 4-8 years. The study sample comprised 4332 children from the first nationally representative Longitudinal Study of Australian Children (LSAC. Predictors were modeled as risk variables with the lowest level of risk as the reference category. In the multivariate model, risks for receptive vocabulary delay at 4 years, in order of magnitude, were: Maternal Non- English Speaking Background (NESB, low school readiness, child not read to at home, four or more siblings, low family income, low birthweight, low maternal education, maternal mental health distress, low maternal parenting consistency, and high child temperament reactivity. None of these risks were associated with a lower rate of growth from 4-8 years. Instead, maternal NESB, low school readiness and maternal mental health distress were associated with a higher rate of growth, although not sufficient to close the receptive vocabulary gap for children with and without these risks at 8 years. Socio-economic area disadvantage, was not a risk for low receptive vocabulary ability at 4 years but was the only risk associated with a lower rate of growth in receptive vocabulary ability. At 8 years, the gap between children with and without socio-economic area disadvantage was equivalent to eight months of receptive vocabulary growth. These results are consistent with other studies that have shown that social gradients in children

2009-07-01

Full Text Available Abstract Background Amblyopia and amblyogenic factors like strabismus and refractive errors are the most common vision disorders in children. Although different studies suggest that preschool vision screening is associated with a reduced prevalence rate of amblyopia, the value of these programmes is the subject of a continuing scientific and health policy discussion. Therefore, this systematic review focuses on the question of whether screening for amblyopia in children up to the age of six years leads to better vision outcomes. Methods Ten bibliographic databases were searched for randomised controlled trials, non-randomised controlled trials and cohort studies with no limitations to a specific year of publication and language. The searches were supplemented by handsearching the bibliographies of included studies and reviews to identify articles not captured through our main search strategy. Results Five studies met the inclusion criteria. Of these, three studies suggested that screening is associated with an absolute reduction in the prevalence of amblyopia between 0.9% and 1.6% (relative reduction: between 45% and 62%. However, the studies showed weaknesses, limiting the validity and reliability of their findings. The main limitation was that studies with significant results considered only a proportion of the originally recruited children in their analysis. On the other hand, retrospective sample size calculation indicated that the power based on the cohort size was not sufficient to detect small changes between the groups. Outcome parameters such as quality of life or adverse effects of screening have not been adequately investigated in the literature currently available. Conclusion Population based preschool vision screening programmes cannot be sufficiently assessed by the literature currently available. However, it is most likely that the present systematic review contains the most detailed description of the main limitations in current

To obtain and analyze data from the social skills evaluation of dysphonic children. This is a cross-sectional and prospective study. Participants were 38 children enrolled in a public school, ranging in age from 7 to 11 years. They were separated into two groups: Study Group (SG)--19 dysphonic children; Control Group (CG)--19 non-dysphonic children. The groups were matched by gender and age range. Children with any history of organic vocal problems, according to the identification and investigation of general and vocal health questionnaire, which was answered by the legal guardian, were excluded. The Multimedia Social Skills Inventoire for Children (MUSSIC) was applied, which consists of 21 social interaction situations represented by photos, having a child as the leading figure. For each situation, the participant should select one out of three behaviors, putting themselves in the place of the main character. Each response corresponds to one out of three types of reaction: assertive, passive and aggressive. Data were statistically analyzed. There was no difference between the groups on the social skills evaluation results, that is, SG and CG children presented similar scores regarding assertiveness, aggressiveness and passiveness. Consequently, there was no difference on the subscales of the inventory regarding social skills. As for the SG, there was no relationship between the scores obtained on the MUSSIC and the severity of the voice disorder. It is not possible to determine specific behaviors of dysphonic children concerning social skills.

This paper studies changes in subjective indoor air quality (SIAQ) among school children and relates these data to repeated exposure measurements during a two-year follow-up period. Data on SIAQ and demographic information were gathered by a questionnaire sent to 1476 primary and secondary school pupils in 39 randomly selected schools at baseline and after two years (follow-up). Exposure measurements were applied after questionnaire data were collected at baseline and follow-up in approximately 100 classrooms. The arithmetic mean values for baseline and follow-up were: for indoor air temperature 23.6°C and 21.8°C and for outdoor air flow rate 5.4 L/s and 7.9L/s. Older children, those with atopy at baseline, and those in larger schools reported impaired SIAQ during follow-up. Installation of new ventilation systems, higher personal air flow rate and air exchange rate, and better illumination were associated with improved SIAQ. Higher CO2 levels were associated with impaired SIAQ. In conclusion, sufficient ventilation and illumination in classrooms are essential for the perception of good indoor air quality.

Bilastine is an H 1 antagonist whose pharmacokinetics (PK) and pharmacodynamics (PD) have been resolved in adults with a therapeutic oral dose of 20 mg/day. Bilastine has favorable characteristics for use in pediatrics but the PK/PD and the optimal dose in children had yet to be clinically explored. The purpose is to: (1) Develop an ontogenic predictive model of bilastine PK linked to the PD in adults by integrating current knowledge; (2) Use the model to design a PK study in children; (3) Confirm the selected dose and the study design through the evaluation of model predictability in the first recruited children; (4) Consider for inclusion the group of younger children (design an adaptive PK trial in children that was then confirmed using data from the first recruits by comparing observations with model predictions. PK/PD simulations supported the selection of 10 mg/day in 2 to design hence trial continuation. The model successfully predicted bilastine PK in pediatrics and optimally assisted the selection of the dose and sampling scheme for the trial in children. The selected dose was considered suitable for younger children and the forthcoming safety study in children aged 2 to <12 years.

To analyze the association between sleep duration and athletic performance, and provide scientific basis to improve the 50 m and endurance performance in children and adolescents. All the 119 462 subjects aged 9-15 years in both genders were sampled from 2014 National Physical Fitness and Health Surveillance by using stratified random cluster sampling method, to measure the height, weight, 50 meters and endurance performance and investigate sleep duration with questionnaire. Their body mass indexes (BMI) were calculated and the students' 50 m, endurance run scores and sleep durations were assessed. Binary Logistic regression was used to analyze the difference between the different sleep groups, and multifactor Logistic regression was used to analyze the relationship between the sleep condition and athletic performance. The prevalence of insufficient sleep was 94.67% in the total subjects, the prevalence was higher among the girls (95.26%)than the boys (94.09%, χ 2 =80.99, Pchildren with sufficient sleep had better performance in 50 m and endurance run scores( χ 2 50 m =10.10, P 50 m ＜0.01; χ 2 endurance run =21.76, Pchildren with adequate sleep showed better results(OR 50 m =1.14, 95%CI 50 m =1.05-1.23, P 50 m endurance run =1.21, 95%CI endurance run =1.11-1.31, P endurance run endurance run scores in the boys with adequate sleep were higher (Pendurance run excellent rates in the girls of different sleep conditions.

2017-11-01

The Malaysian government had targeted for the rice industry in the country to achieve 100% rice self-sufficiency where Malaysia's rice self-sufficiency level (SSL) is currently at 65% to 75%. Thus, the government had implemented few policies to increase the rice production in Malaysia in order to meet the growing demand of rice. In this paper, the effect of price support on the rice production system in Malaysia is investigated. This study utilizes the system dynamics approach of the rice production system in Malaysia where the complexity of the factor is interrelated and changed dynamically through time. Scenario analysis was conducted using system dynamics model by making changes on the price subsidy to see its effect on the rice production and rice SSL. The system dynamics model provides a framework for understanding the effect of price subsidy on the rice self-sufficiency level. The scenario analysis of the model shows that a 50% increase in the price subsidy leads to a substantial increase in demand as the rice price drops. Accordingly, the local production increases by 15%. However, the SSL slightly decreases as the local production is insufficient to meet the large demand.

Children employed in the performing arts, advertising and fashion industry: what legal protection do they have?

2009-09-01

Ill-treatment can sometimes take on an unfamiliar face. Particularly, this is the case for certain types of child employment. In France, as in most European countries, there are laws for protecting children and guaranteeing their right to schooling. Over and above the frequently observed apprenticeship contracts, obtained by eligible under 16 years, there is also the dispensatory case of children employed in the performing arts, advertising and the fashion industry. In France, legislators take the child's vulnerability into account when developing legislative and regulatory mechanisms, concerning the modalities of his/her professional activity, particularly in artistic fields and in fashion modelling. Since both may employ very young children, or even infants, one essential question ought to be raised: from a legal point of view, are these children sufficiently protected, with regard to the potential physical and psychological consequences of their particular professional activities?

2007-09-01

The New England Children's Amalgam Trial (NECAT) was a five-year randomized trial of 534 6- to 10-year-old children that compared the neuropsychological outcomes of those whose caries were restored using dental amalgam with the outcomes of those those whose caries were restored using mercury-free resin-based composite. The primary intention-to-treat analyses did not reveal significant differences between the treatment groups on the primary or secondary outcomes of the administered psychological tests: Full-Scale IQ score on the Wechsler Intelligence Scale for Children-Third Edition, General Memory Index of the Wide Range Assessment of Memory and Learning, and Visual-Motor Composite of the Wide Range Assessment of Visual Motor Abilities. To determine whether treatment group assignment, a dichotomous measure of exposure, was sufficiently sensitive to detect associations between mercury exposure and these outcomes, the authors conducted analyses to evaluate the associations between the primary and secondary outcomes and two continuously distributed indexes of potential exposure, surface-years of amalgam and urinary mercury excretion. Neither index of mercury exposure was significantly associated with any of the three outcomes. The authors found no evidence that exposure to mercury from dental amalgam was associated with any adverse neuropsychological effects over the five-year period after placement of amalgam restorations. Analyses of the outcomes of the NECAT study indicate that use of dental amalgam was not associated with an increase in children's risk of experiencing neuropsychological dysfunction.

This report describes experimental observations made in connection with a magnetically collimated arc having an applied pressure gradient along its length and presents possible explanations of the phenomena observed. It is believed to be pertinent to thermonuclear research because it involves the transport of plasma across a magnetic field and the acceleration of ions without use of solid electrodes and furnishes evidence concerning the behavior inside magnetically collimated arc discharges as the pressure is decreased. The observations are repeatable to an unusual degree and are believed to be sufficiently interesting to be reported at this time, even though a thorough understanding of the entire mechanism involved has not been reached.

Quantitative analysis of disfluency in children with autism spectrum disorder or language impairment.

Directory of Open Access Journals (Sweden)

Heather MacFarlane

Full Text Available Deficits in social communication, particularly pragmatic language, are characteristic of individuals with autism spectrum disorder (ASD. Speech disfluencies may serve pragmatic functions such as cueing speaking problems. Previous studies have found that speakers with ASD differ from typically developing (TD speakers in the types and patterns of disfluencies they produce, but fail to provide sufficiently detailed characterizations of the methods used to categorize and quantify disfluency, making cross-study comparison difficult. In this study we propose a simple schema for classifying major disfluency types, and use this schema in an exploratory analysis of differences in disfluency rates and patterns among children with ASD compared to TD and language impaired (SLI groups. 115 children ages 4-8 participated in the study (ASD = 51; SLI = 20; TD = 44, completing a battery of experimental tasks and assessments. Measures of morphological and syntactic complexity, as well as word and disfluency counts, were derived from transcripts of the Autism Diagnostic Observation Schedule (ADOS. High inter-annotator agreement was obtained with the use of the proposed schema. Analyses showed ASD children produced a higher ratio of content to filler disfluencies than TD children. Relative frequencies of repetitions, revisions, and false starts did not differ significantly between groups. TD children also produced more cued disfluencies than ASD children.

Motivation for physical activity in children: a moving matter in need for study.

Motivation for physical activity in children below the age of 12 years is a largely underrepresented issue in contemporary research. Although engagement in sufficient physical activity is highly important for children's current and later health, relatively little is known of the factors that motivate children to be physically active. Various theories have been developed in an attempt to explain motivation toward physical activity in adults. Recent developments have focussed on integrating constructs of these theories in order to attain a comprehensive account of motivated behavior. The relationships between different motivational constructs have generally been investigated in healthy adolescents and adults. This manuscript outlines why more theoretically driven research into children's motivation toward physical activity is needed. Constructs stemming from various motivational theories and their interrelationship as evidenced in youth and adults will be summarized. The current state of research on the applicability of these motivational constructs to children, and the generalizability of the interrelationship between the constructs to child samples will be outlined. A deeper insight into the motivational determinants of physical activity participation in children could inform the design of interventions to facilitate the development of physically active lifestyles that persist at older ages.

Full Text Available Purpose: Cochlear implants (CIs enable children with severe and profound hearing impairments to perceive the sensation of sound sufficiently to permit oral language acquisition. So far, studies have focused mainly on technological improvements and general outcomes of implantation for speech perception and spoken language development. This study quantitatively explored the semantic networks of children with CIs in comparison to those of age-matched normal hearing (NH peers.Method: Twenty seven children with CIs and twenty seven age- and IQ-matched NH children ages 7-10 were tested on a timed animal verbal fluency task (Name as many animals as you can. The responses were analyzed using correlation and network methodologies. The structure of the animal category semantic networks for both groups were extracted and compared.Results: Children with CIs appeared to have a less-developed semantic lexicon structure compared to age-matched NH peers. The average shortest path length and the network diameter measures were larger for the NH group compared to the CIs group. This difference was consistent for the analysis of networks derived from animal names generated by each group (sample-matched correlation networks and for the networks derived from the common animal names generated by both groups (word-matched correlation networks.Conclusions: The main difference between the semantic networks of children with CIs and NH children lies in the network structure. The semantic network of children with CIs is under-developed compared to the semantic network of the age-matched NH children. We discuss the practical and clinical implications of our findings.

[Ambulant compression therapy for crural ulcers; an effective treatment when applied skilfully].

The incidence of crural ulcers is high. They reduce quality of life considerably and create a burden on the healthcare budget. The key treatment is ambulant compression therapy (ACT). We describe two patients with crural ulcers whose ambulant compression treatment was suboptimal and did not result in healing. When the bandages were applied correctly healing was achieved. If correctly applied ACT should provide sufficient pressure to eliminate oedema, whilst taking local circumstances such as bony structures and arterial qualities into consideration. To provide pressure-to-measure regular practical training, skills and regular quality checks are needed. Knowledge of the properties of bandages and the proper use of materials for padding under the bandage enables good personalised ACT. In trained hands adequate compression and making use of simple bandages and dressings provides good care for patients suffering from crural ulcers in contrast to inadequate ACT using the same materials.
