Self-Organized Networks and Lattice Effects in High Temperature Superconductors III: Dopant Internal Structure

The self-organized dopant percolative filamentary model, entirely orbital in character (no fictive spins), predicted the existence and even the ~ 3 nm diameters of gap nanodomains (discovered by STM) that amazed almost all theorists in this field. Here it explores the self-consistent and self-limiting coupling between dopant sites and gap character. It explains precursive magnetic effects and shows that they are caused by dopant ordering into loops at an onset temperature of order 2Tc. The ordered coupling of these loops by filamentary connectors is reflected by Debye-Waller factors, and it apparently leads to HTSC. The model also resolves the mystery of the vanishing isotope effect, and it explains the origin of the high-energy "waterfall" recently discovered by ARPES, as well as some overlooked infrared anomalies.
Comments on the Sign and Other Aspects of Semiclassical Casimir Energies

The Casimir energy of a massless scalar ﬁeld is semiclassically given by contributions due to classical periodic rays. The required subtractions in the spectral density are determined explicitly. The so deﬁned semiclassical Casimir energy coincides with that obtained using zeta function regularization in the cases studied. Poles in the analytic continuation of zeta function regularization are related to non-universal subtractions in the spectral density. The sign of the Casimir energy of a scalar ﬁeld on a smooth manifold is estimated by the sign of the contribution due to the shortest periodic rays only. De-manding continuity of the Casimir energy under small deformations of the manifold, the method is extended to integrable systems. The Casimir energy of a massless scalar ﬁeld on a manifold with boundaries includes contributions due to periodic rays that lie entirely within the boundaries. These contributions in general depend on the boundary conditions. Although the Casimir energy due to a massless scalar ﬁeld may be sensitive to the physical dimensions of manifolds with boundary, its sign can in favorable cases be inferred without explicit calculation of the Casimir energy.
Long-Term Effects of the 1959-1961 China Famine: Mainland China and Hong Kong

This paper estimates the effects of maternal malnutrition exploiting the 1959-1961 Chinese famine as a natural experiment. In the 1% sample of the 2000 Chinese Census, we find that fetal exposure to acute maternal malnutrition had compromised a range of socioeconomic outcomes, including: literacy, labor market status, wealth and marriage market outcomes. Women married spouses with less education and later, as did men, if at all. In addition, maternal malnutrition reduced the sex ratio (males to females) in two generations -- those prenatally exposed and their children -- presumably through heightened male mortality. This tendency toward female offspring is interpretable in light of the Trivers-Willard (1973) hypothesis, according to which parents in poor condition should skew the offspring sex ratio toward daughters. Hong Kong natality micro data from 1984-2004 further confirm this pattern of female offspring among mainland-born residents exposed to malnutrition in utero.
Alternative assessment and the teaching of mother tongue languages in Singapore schools

The mother tongue education component of Singapore’s bilingual policy aims at achieving a dual goal of empowering its citizens with linguistic capital (which they can use in interacting with people from emerging regional powers) and moral capital (which can help maintain their Asian value and identity). Unfortunately, this goal has seldom been adequately achieved. Among the various affecting factors, the unique language learning environment and the exam-oriented language teaching and assessment practices have imposed great constraints on the attainment of the wonderful intention of policy makers. One piece of evidence is that daily assessment practices in MT teaching focus too much on factual knowledge and knowledge reproduction which are characterized by examining discrete linguistic knowledge and practice and drills. To further improve the teaching of Mother Tongue languages in Singapore and better attain the dual goal, we may need to introduce new assessment practices into daily classroom teaching: alternative assessment practices. This paper presents an overview about the necessity, feasibility, advantages, how the use of alternative assessments can improve the quality of MT teaching and learning in the actual classroom context, and the practical constraints of introducing alternative assessment into MT education.
Distance learning training in genetics and genomics testing for Italian health professionals: results of a pre and post-test evaluation

Background Progressive advances in technologies for DNA sequencing and decreasing costs are allowing an easier diffusion of genetic and genomic tests. Physicians’ knowledge and confidence on the topic is often low and not suitable for manage this challenge. Tailored educational programs are required to reach a more and more appropriate use of genetic technologies. Methods A distance learning course has been created by experts from different Italian medical associations with the support of the Italian Ministry of Health. The course was directed to professional figures involved in prescription and interpretation of genetic tests. A pretest-post-test study design was used to assess knowledge improvement. We analyzed the proportion of correct answers for each question pre and post-test, as well as the mean score difference stratified by gender, age, professional status and medical specialty. Results We reported an improvement in the proportion of correct answers for 12 over 15 questions of the test. The overall mean score to the questions significantly increased in the post-test, from 9.44 to 12.49 (p-value < 0.0001). In the stratified analysis we reported an improvement in the knowledge of all the groups except for geneticists; the pre-course mean score of this group was already very high and did not improve significantly. Conclusion Distance learning is effective in improving the level of genetic knowledge. In the future, it will be useful to analyze which specialists have more advantage from genetic education, in order to plan more tailored education for medical professionals.
Problems of Harmonic Analysis related to finite type hypersurfaces in R^3, and Newton polyhedra

This article is intended to give an overview on a collection of results which have been obtained jointly with I.I. Ikromov, and in parts also with M. Kempe, and at the same time to give a kind of guided tour through the rather comprehensive proofs of the major results that I shall address. All of our work is highly inﬂuenced by the pioneering ideas developed by E.M. Stein. Consider a smooth hypersurface S in R 3 of ﬁnite type, and let dµ = ρdσ be a surface carried measure with smooth, compactly supported density ρ ≥ 0 with respect to the surface measure dσ. The problems that I shall address are the following ones: holds true. The ﬁrst problem is classical, and the other ones originate from seminal contributions by E.M. Stein. These problems are somewhat interrelated, and in particular it is well-known that the answers to B and C are strongly inﬂuenced by the answer to A. Moreover, due to the insights by V.I. Arnol’d and his school, in particular through work by A.N. Varchenko and V.N. Karpushkin, we know that the answer to problem A can be given in terms of Newton polyhedra associated to the given hypersurface S, at least for analytic hypersurfaces. That Newton polyhedra would play an important role also in other problems of harmonic analysis has been stressed later in pioneering work by D.H. Phong and E.M. Stein on oscillatory integral operators.Inthisarticle, I shall outline how (almost) complete answers to the above questions can be given again in terms of associated Newton polyhedra (for question B, at least if p > 2).
Association between abdominal and gynoid fat mass, metabolism markers and serum androgens in obese women with polycystic ovary syndrome**

Aim. To evaluate associations between abdominal and gynoid fat, glucose and lipid metabolism markers and serum androgens in obese women with polycystic ovary syndrome (PCOS). Material and methods. In 20 women with PCOS aged 19-49 years with body mass index (BMI) 27.3-53.8 kg/m2 anthropometric measurements were performed. Fasting serum glucose, lipids, insulin, leptin, LH, FSH, estradiol, androgens, SHBG, fT4 and TSH were estimated. Body composition was measured by DEXA scan. Results. All of the subjects had increased abdominal fat and were hyperandrogenic, seven of them had elevated fasting serum insulin levels, and fifteen were insulin resistant. BMI, abdominal fat and waist circumference (WC) positively correlated with triglycerides (r = 0.45, p < 0.05; r = 0.45, p < 0.05; r = 0.56, p < 0.01, respectively), insulin (r = 0.79, p < 0.001; r = 0.61, p < 0.01; r = 0.71, p < 0.01, respectively), and systolic blood pressure (r = 0.68, p < 0.001; r = 0.59, p < 0.01; r = 0.58, p < 0.01, respectively). We found a correlation between leptin levels and body weight (r = 0.68, p < 0.05), BMI (r = 0.67, p < 0.05), total fat (r = 0.62, p < 0.05) and WC (r = 0.83, p < 0.01). No direct correlation between fat mass indices and sex hormones were found. We observed a correlation between androgens and TSH: androstendione (r = 0.61, p = 0.0065) and DHEA-S (r = 0.64, p = 0.01). Conclusions. DEXA is a valuable method of body composition assessment in women with PCOS. Studied subjects had abdominal type of obesity. There was a positive correlation between abdominal obesity and cardiovascular risk factors: triglyceride and insulin levels and blood pressure. We did not prove any direct association between fatness and serum androgens but correlation between androgens and TSH was found.
Evaluación de la calidad de atención a la salud de adolescentes en el prenatal y en el puerperio

Resumen It is an evaluative study aimed to assess the quality of prenatal and postpartum for adolescents with children born alive in a public health institution in Teresina, Piauí. Two parameters were used to evaluate the prenatal care: an international index (Adequacy of Prenatal Care Utilization) and a national one, based on recommendations from the Ministry of Health. The quality of care was categorized as more appropriate, adequate, intermediate and inadequate. It was noticed that more than half of the women began the prenatal care at an early stage and the number of visits for prenatal care was inadequate. Most of them performed the ordinary prenatal exams, 75% had their breasts examined and 88.6% were advised about breastfeeding. The postpartum care was intermediate to 38.6% of women, 52.3% did not return to the health unit, nor received home visit, 70.5% were advised about contraceptive methods and 93.2% on breastfeeding. Efforts should be undertaken to ensure the quality of care in pregnancy up to the puerperium.
The dynamics of viral marketing

We present an analysis of a person-to-person recommendation network, consisting of 4 million people who made 16 million recommendations on half a million products. We observe the propagation of recommendations and the cascade sizes, which we explain by a simple stochastic model. We then establish how the recommendation network grows over time and how effective it is from the viewpoint of the sender and receiver of the recommendations. While on average recommendations are not very effective at inducing purchases and do not spread very far, we present a model that successfully identifies product and pricing categories for which viral marketing seems to be very effective.

Termos de indexacao : avaliacao nutricional; desnutricao proteico-energetica; tuberculose pulmonar.
Structural modeling of relationship between professional ethics and spirituality at work with social responsibility among nurses in the public hospitals in Kermanshah city

Introduction: The concept of social responsibility is a key issue in health management system, which a comprehensive survey of it, needs to identify so many variables. Essential challenge for nurse managers in planning is reorganization the main variable which is important effect on nurses’ organizational behavior. Professional ethics and spirituality at work are among variables which are effective on social responsibility. Aim: The aim of study was examination of structural modeling of relationship between professional ethics and spirituality at work with social responsibility among nurses in the public hospitals of Kermanshah city. Method: The study was descriptive-correlation. The population of the study was all staff nurses in two public hospitals (N=386) of Kermanshah city in 2013. According to the Morgan table (157) of them were selected randomly. Three standard questionnaires were used: Professional Ethics questionnaire (Cadozier, 2002); Spirituality at work (Milliman & et al, 2003) and Social Responsibility (Apaydin & Ercan, 2010). Their reliabilities by α- chronbach were (0.79, 0.80 & 0.70) respectively. For data analysis, structural equation modeling was used through Lisrel 8.72 software. Results: The findings showed that there is a significant positive relationship between professional ethics and spirituality (t = 2.55, P< 0/05), and between spirituality and social responsibility at work (t= 2.28, P< 0/05). Also, spirituality played a mediator role, in relationship between ethics and social responsibility; this mean is professional ethics have indirect and significant positive effect on nurses’ social responsibility at work. Conclusion: Nurse managers and hospitals administrators must be prepared context and work environment for nurses which they feel valuable, effective and useful and eventually promote their responsibility towards patients, organization and society.

An inflow-boundary-based Navier-Stokes wave tank: verification and validation for waves propagating over flat and inclined bottoms.

Development of mass-source function based numerical wave tank (NWT) algorithms in the Navier-Stokes (NSE) framework is impeded by multiple design issues such as: (a) optimization of a number of variables characterizing the source region, (b) wave-vorticity interactions and (c) a mandatory requirement of modeling the domain on both sides of the wavemaker. In this paper, we circumvent these hurdles by proposing a volume-preserving inflow-boundary based Navier-Stokes wave tank. Wave generation and propagation is modeled in a two-phase PLIC-VOF set-up. Near-exact volume preservation is achieved (at arbitrarily large steepness) using kinematic stretching that is aimed towards balancing the streamwise momentum between points lying above and below the still water level. Numerical damping of steep waves is prevented by using blended third-order and limiter schemes for momentum advection. In addition, a mesh stair-stepping strategy has been adopted for modeling non-Cartesian immersed boundaries on a staggered variable arrangement. The proposed NWT model is rigorously benchmarked against various wave-propagation scenarios. These include the simulation of: (a) monochromatic waves of various steepnesses, (b) monochromatic waves superimposed with free harmonics, (c) irregular waves in deep water and (d) wave transformation occurring over a submerged trapezoidal bar. Excellent agreement with analytical, numerical and experimental data is reported with both validation as well as verification of the proposed NWT model being established.
Ocular fundus changes in pre-eclampsia and eclampsia in a rural set-up

Context: Pregnancy-induced hypertension (PIH) is one of the common complications met with pregnancy and contributes significantly to maternal and fetal mortality and morbidity. Aims: To grade the ocular fundus changes in patients of pre-eclampsia and eclampsia. Settings and Design: Hospital-based prospective observational study. Materials and Methods: Hospital-based prospective observational study conducted over a period of 2 years. One hundred patients of pregnancy having pre-eclampsia and eclampsia were included. Statistical analysis used: Chi-square test. Results: Out of 100 cases, 32 (32%) had mild pre-eclampsia while 50 (50%) had severe pre-eclampsia. Eighteen (18%) patients had eclampsia. Out of 100 cases examined in this study, 54 presented with ocular symptoms and 46 were asymptomatic. Arteriolar attenuation was the most common retinal change observed and it was seen in 44 (44%) cases. Exudative retinal detachment was seen in 7 (7%) cases and macular edema was present in 12 (12%) cases of PIH. Conclusions: Cases of severe pre-eclampsia and of eclampsia showed higher grades of retinal changes. Visual disturbances and symptoms like headache were commonly associated with retinal changes. It is essential to examine each and every patient of pre-eclampsia and eclampsia for ocular manifestations, which should be helpful for obstetrician in the management of patient.

OBJETIVO: Avaliar os parâmetros de iodo no sal e na urina em populacoes de escolares de instituicoes de ensino fundamental caracterizadas por atender alunos de niveis socioeconomicos opostos. METODOS: Foram recolhidas amostras de urina de escolares de duas escolas, uma particular e a outra publica, do municipio de Ouro Preto, MG, bem como amostras de sal de consumo humano utilizado em suas residencias. Dosou-se o teor de iodo nas amostras de urina e de sal a fim de estabelecer uma correlacao entre a concentracao de iodo na urina e no sal. Foi utilizado o teste de Mantel-Haenszel para medir a associacao entre o sal e a urina. RESULTADOS: Os niveis de concentracao de iodo na urina foram considerados normais em 92,2% dos alunos da escola particular e em 42,6% dos alunos da escola municipal. Na dosagem do teor de iodo no sal de consumo humano ingerido pelos alunos da escola publica, 89,9% das amostras apresentaram niveis abaixo da exigencia legal. No caso dos alunos da escola particular, esse valor foi de 40,9%. CONCLUSOES: Verificou-se a ocorrencia de associacao inversa, estatisticamente significante, entre as concentracoes de iodo no sal e na urina. Identificaram-se teores de iodo abaixo da exigencia legal no sal consumido pelos escolares e um nivel significativo de deficiencia de iodo na urina. Tais ocorrencias afetaram mais drasticamente, de forma estatisticamente significante, os alunos da escola publica.
Prevalência de pré-hipertensão e de hipertensão arterial e avaliação de fatores associados em crianças e adolescentes de escolas públicas de Salvador, Bahia, Brasil

This study aimed to assess pre-hypertension and hypertension-related factors in 1,125 seven- to-14-year-old subjects enrolled in the public school system in Salvador, Bahia State, Brazil. Exposure variables, namely body mass index, waist circumference, gender, age, physical activity, environmental and housing status, family income, diet, schooling, and maternal age were analyzed by polytomous logistic regression, and the outcome variable was categorized as normal, pre-hypertensive, and hypertensive. Prevalence of high blood pressure was 14.1%, including the prevalence of both hypertension (4.8%) and pre-hypertension (9.3%). An association was shown between pre-hypertension and overweight (OR: 3.13; 95%CI: 1.75-5.57). Hypertension was associated with overweight (OR: 3.02; 95%CI: 1.45-6.28), female gender (OR: 2.49; 95%CI: 1.24-4.98), and high-risk eating patterns (OR: 1.93; 95%CI: 1.04-3.56). In short, prevalence of pre-hypertension and hypertension in children and adolescents was higher among girls and individuals with overweight and inadequate diet.
Updated search for the flavor-changing neutral-current decay D{sup 0}{yields}{mu}{sup +}{mu}{sup -} in pp collisions at {radical}(s)=1.96 TeV

We report on a search for the flavor-changing neutral-current decay D{sup 0}{yields}{mu}{sup +}{mu}{sup -} in pp collisions at {radical}(s)=1.96 TeV using 360 pb{sup -1} of integrated luminosity collected by the CDF II detector at the Fermilab Tevatron collider. A displaced vertex trigger selects long-lived D{sup 0} candidates in the {mu}{sup +}{mu}{sup -}, {pi}{sup +}{pi}{sup -}, and K{sup -}{pi}{sup +} decay modes. We use the Cabibbo-favored D{sup 0}{yields}K{sup -}{pi}{sup +} channel to optimize the selection criteria in an unbiased manner, and the kinematically similar D{sup 0}{yields}{pi}{sup +}{pi}{sup -} channel for normalization. We set an upper limit on the branching fraction B(D{sup 0}{yields}{mu}{sup +}{mu}{sup -})<2.1x10{sup -7}(3.0x10{sup -7}) at the 90% (95%) confidence level.
