    Exposure to low socioeconomic status (SES) in childhood predicts increased morbidity and mortality. However, little prospective evidence is available to test pathways linking low childhood SES to adult health. In the current study, indirect effects through positive parenting in adolescence and adult SES were tested in the association between childhood SES and adult health behaviors and psychological resources. Men (n = 305; 53% Black) were followed longitudinally from ages 7 to 32. SES was measured annually in childhood (ages 7-9) and again in adulthood (age 32) using the Hollingshead index. Parenting was assessed annually (ages 13-16) using caregivers' and boys' self-report of supervision, communication, and expectations for their son's future. Health behaviors (cigarette and alcohol use, fruit and vegetable consumption, and physical activity) and psychological resources (optimism, purpose in life, self-mastery, and self-esteem) were assessed in adulthood (age 32). Structural equation modeling showed that higher childhood SES was associated with more positive parenting in adolescence and higher adult SES. Higher childhood SES was indirectly associated with healthier behaviors and higher psychological resources in adulthood through pathways involving positive parenting during adolescence and SES in adulthood. Findings were consistent in both racial groups. Positive parenting in adolescence was an important pathway in understanding associations among childhood SES and health behaviors and psychological resources in adulthood. Low childhood SES was prospectively associated with healthier behaviors and greater psychological resources in part through more positive parenting in adolescence.

    Damaske, Sarah; Zawadzki, Matthew J; Smyth, Joshua M

    2016-05-01

    This paper asks whether workers with higher socioeconomic status (SES) experience different levels of stress at work than workers with lower SES and, if so, what might explain these differences. We collected innovative assessments of immediate objective and subjective measures of stress at multiple time points across consecutive days from 122 employed men and women. We find that in comparison to higher SES individuals, those with lower SES reported greater happiness at work, less self-reported stress, and less perceived stress; cortisol, a biological marker of stress, was unrelated to SES. Worker's momentary perceptions of the workplace were predicted by SES, with higher SES individuals more commonly reporting feeling unable to meet work demands, fewer work resources, and less positive work appraisals. In turn, perceptions of the workplace had a generally consistent and robust effect on positive mood, subjective stress, and cortisol. Copyright © 2016 Elsevier Ltd. All rights reserved.

  5. Job Pressure and SES-contingent Buffering: Resource Reinforcement, Substitution, or the Stress of Higher Status?

    Science.gov (United States)

    Koltai, Jonathan; Schieman, Scott

    2015-06-01

    Analyses of the 2008 National Study of the Changing Workforce demonstrate that job pressure is associated with greater anxiety and job dissatisfaction. In this paper we ask, What conditions protect workers? The conventional buffering hypothesis in the Job-Demands Resource (JD-R) model predicts that job resources should attenuate the relationship. We test whether the conventional buffering hypothesis depends on socioeconomic status (SES). Support for conventional buffering is evident only for job dissatisfaction--and that generalizes across SES. When anxiety is assessed, however, we observe an SES contingency: Job resources attenuate the positive association between job pressure and anxiety among workers with lower SES, but exacerbate it among those with higher SES. We discuss the implications of this SES-contingent pattern for theoretical scenarios about "resource reinforcement," "resource substitution," and the "stress of higher status." Future research should consider SES indicators as potential contingencies in the relationship between job conditions and mental health. © American Sociological Association 2015.

    BACKGROUND: Although research into the continuity and change of personality traits during a lifespan has been fairly extensive, little research has been conducted on childhood predictors of adult personality. PURPOSE: We aimed to investigate the association between infant socioeconomic status (SES......), and Eysenck personality traits in adulthood. An additional aim was to investigate whether intelligence and education may mediate this association. METHODS: SES of 9125 children in the Copenhagen Perinatal Cohort was recorded at a 1-year examination. A subsample of this cohort, comprising 1182 individuals......, participated in a follow-up at 20-34 years and was administered the Eysenck Personality Questionnaire (EPQ) which includes measures of neuroticism, extraversion, psychoticism and the so-called lie-scale. Associations of SES with each of the four personality traits were analysed by bivariate and partial...

    Objective. This study examined how family environmental characteristics served as mediators in the relationship between socioeconomic conditions and infant growth in a cohort of Chilean infants. Methods. We studied 999 infants, born between 1991 and 1996, from a longitudinal cohort which began as an iron deficiency anemia preventive trial. SES (Graffar Index), the Life Experiences Survey, and the Home Observation for Measurement of the Environment (HOME) were assessed in infancy. Using path analysis, we assessed the relationships between the social factors, home environment, and infant growth. Results. During the first year, weight and length gain averaged 540 grams/month and 6.5 cm/month, respectively. In the path analysis model for weight gain, higher SES and a better physical environment were positively related to higher maternal warmth, which in turn was associated with higher average weight gain. Higher SES was directly related to higher average length gain. Conclusions. In our cohort, a direct relationship between SES and length gain developed during infancy. Higher SES was indirectly related to infant weight gain through the home environment and maternal warmth. As the fastest growing infants are at risk for later obesity, new strategies are needed to encourage optimal rather than maximal growth. PMID:22666275

  17. A SES (sustainable energy security) index for developing countries

    International Nuclear Information System (INIS)

    Narula, Kapil; Reddy, B. Sudhakara

    2016-01-01

    Measuring the performance of the energy system of a country is a prerequisite for framing good energy polices. However, the existing indices which claim to measure energy security have limited applicability for developing countries. Energy sustainability is also increasingly gaining importance and countries are keen to measure it to tailor their energy policies. Therefore, the concept of SES (sustainable energy security) has been proposed as the goal for a developing country. This paper presents an analytical framework for the assessment of SES of an energy system and the methodology for constructing an SES index. A hierarchical structure has been proposed and the energy system has been divided into 'supply', 'conversion & distribution' and 'demand' sub-systems. Each subsystem is further divided into its components which are evaluated for four dimensions of SES, Availability, Affordability, Efficiency and (Environmental) Acceptability using quantitative metrics. Energy indices are constructed using 'scores' (objective values), and 'weights' (subjective values representing tradeoffs) which are then aggregated, bottom-up, to obtain an overall SES Index for a country. The proposed SES Index is multidimensional, quantitative, modular, systemic and flexible. Such a SES Index can be used to design policy interventions for transitioning to a sustainable and a secure energy future. - Highlights: • A SES (sustainable energy security) index is proposed for developing countries. • A hierarchical structure includes the entire energy system from supply to end use. • The performance of all energy sources, energy carriers and sectors is assessed. • Availability, affordability, efficiency and acceptability dimensions are evaluated. • The SES index is multidimensional, quantitative, modular, systemic and flexible.

    2016-01-01

    Socioeconomic status (SES) is a complex construct of multiple indicators, known to impact cancer outcomes, but has not been adequately examined among pediatric AML patients. This study aimed to identify the patterns of co-occurrence of multiple community-level SES indicators and to explore associations between various patterns of these indicators and pediatric AML mortality risk. A nationally representative US sample of 3,651 pediatric AML patients, aged 0–19 years at diagnosis was drawn from 17 Surveillance, Epidemiology, and End Results (SEER) database registries created between 1973 and 2012. Factor analysis, cluster analysis, stratified univariable and multivariable Cox proportional hazards models were used. Four SES factors accounting for 87% of the variance in SES indicators were identified: F1) economic/educational disadvantage, less immigration; F2) immigration-related features (foreign-born, language-isolation, crowding), less mobility F3) housing instability; and, F4) absence of moving. F1 and F3 showed elevated risk of mortality, adjusted hazards ratios (aHR) (95% CI): 1.07(1.02–1.12) and 1.05(1.00–1.10), respectively. Seven SES-defined cluster groups were identified. Cluster 1: (low economic/educational disadvantage, few immigration-related features, and residential-stability) showed the minimum risk of mortality. Compared to Cluster 1, Cluster 3: (high economic/educational disadvantage, high-mobility) and Cluster 6: (moderately-high economic/educational disadvantages, housing-instability and immigration-related features) exhibited substantially greater risk of mortality, aHR(95% CI) = 1.19(1.0–1.4) and 1.23 (1.1–1.5), respectively. Factors of correlated SES-indicators and their pattern-based groups demonstrated differential risks in the pediatric AML mortality indicating the need of special public-health attention in areas with economic-educational disadvantages, housing-instability and immigration-related features.

    2015-04-01

    The purpose of the research was to determine whether European American and Latino mock jurors would demonstrate bias in death penalty decision making when mitigation evidence and defendant ethnicity and socioeconomic status (SES) were varied. A total of 561 actual venire persons acted as mock jurors and read a trial transcript that varied a defendant's case information (mitigating circumstances: strong/weak, defendant ethnicity: European American/Latino, and defendant SES: low/high). European American jurors recommended the death penalty significantly more often for the low SES Latino defendant when strength of mitigation evidence was weak. In addition, they also assigned this defendant higher culpability ratings and lower ratings on positive personality trait measures compared with all other conditions. Strong mitigation evidence contributed to lower guilt ratings by European American jurors for the high SES European American defendant. Latino jurors did not differ in their death penalty sentencing across defendant mitigation, ethnicity, or SES conditions. Discussion of in-group favoritism and out-group derogation, as well as suggestions for procedures to diminish juror bias in death penalty cases, is provided. (c) 2015 APA, all rights reserved).

  20. Design of SES-10 nuclear reactor for district heating

    1991-03-01

    The SES-10 units are unpressurized, pool-type nuclear reactors of 10MW rating, designed for supplying energy to hot water district heating systems, economically and without pollution. Water for heat distribution is brought to a maximum temperature of 85 degrees C. Conventional heating units supplement the output from SES-10 units for peak load and during maintenance. The SES-10 is housed in a low-cost building, with a double-walled pool in the ground. A naturally circulating primary system and a pumped secondary system transport heat from the reactor to the distribution system. The unit is fully automated and easy to maintain. Because of the many active and passive safety features, it is feasible to license the SES-10 for operation in a city and easy to explain it to the public for their acceptance. The core lasts approximately 43 months at a capacity factor of 70%, and the cost of heat is expected to be 2 to 2.5 cents/kWh

    Language skills, strongly linked to academic success, are known to differ by socioeconomic status (SES), with lower SES individuals performing less well than higher SES. To examine the effect of SES on infant language at 7months of age and the relationship between maternal vocabulary skills and infant language function. To determine if the relationships between SES and infant language are mediated by maternal vocabulary skills. Longitudinal follow-up of healthy term female African American infants born to mothers in two SES groups: Low SES (income-to-needs≤1, no education beyond high school) and Higher SES (Income-to-Needs >1, at least a high school diploma). 54 infants tested at 7months of age; 54 mothers tested at infant age 7months. Preschool Language Scale-5 (PLS-5), Vocabulary and Matrix Reasoning subtests of the Wechsler Adult Intelligence Scale-IV. Low SES infants (n=29) performed less well than Higher SES (n=25) on PLS-5 Total Language, Auditory Comprehension, and Expressive Communication (p≤0.012). Maternal Vocabulary subtest scores were lower in Low SES than Higher SES (p=0.002), but not related to infant PLS Language scores (p≥0.17). Maternal vocabulary did not mediate the relationship between SES and infant language skills at age 7months. In this single sex and race cohort of healthy, term, female infants, lower SES exerted negative effects on infant language by 7months of age. While maternal vocabulary scores showed no relation with infant language skills at 7months, continued study of the relations between SES, infant outcomes and maternal characteristics is needed to determine how low SES conditions impact early language. These findings underscore the importance of early interventions, as well as policies designed to improve socioeconomic conditions for infants and families. Copyright © 2015 Elsevier Ireland Ltd.

    PP and L has been monitoring temperatures in the Susquehanna SES reactor building with digital temperature recorders since 1986. In early 1990, data from four representative areas was analyzed to determine the temperature in each area which would produce the same rate of degradation as the distribution of actual temperatures recorded over about 40 months. From these effective average temperatures, qualified life multipliers were determined for activation energies in the range of 0.5 to 1.5 and those multipliers were used to estimate new qualified lives and the number of replacements which might be saved during the life of the plant. The results indicate that pursuing a program of determining EQ qualified lives from actual temperatures, rather than maximum design basis temperatures, will provide a substantial payback in reduced EQ driven maintenance

    Relationships among symptomatology, socioeconomic status, and parenting styles were examined for 113 hyperkinetic/minimal brain dysfunction boys from intact families. Primary symptoms (e.g. hyperactivity) did not vary as a function of SES, but SES-related differences emerged for secondary symptoms (e.g., aggressive behavior, self-esteem deficits) and for parenting variables. Parenting variables were found to be better predictors of secondary symptoms than was SES. Implications for further research are offered.

    Full Text Available Background: Central nervous system (CNS infections present a grave health care challenge due to high morbidity and mortality. Clinical findings and conventional laboratory assessments are not sufficiently distinct for specific etiologic diagnosis. Identification of pathogens is a key to appropriate therapy. Aim: In this retrospective observational study, we evaluated the efficacy and clinical utility of syndrome evaluation system (SES for diagnosing clinically suspected CNS infections. Materials and Methods: This retrospective analysis included inpatients in our tertiary level neurointensive care unit (NICU and ward from February 2010 to December 2013. Cerebrospinal fluid (CSF samples of 70 patients, clinically suspected of having CNS infections, were subjected to routine laboratory tests, culture, imaging, and SES. We analyzed the efficacy of SES in the diagnosis of CNS infections and its utility in therapeutic decision-making. Results: SES had a clinical sensitivity of 57.4% and clinical specificity of 95.6%. Streptococcus pneumoniae and Pseudomonas aeruginosa were the top two bacterial pathogens, whereas Herpes simplex virus (HSV was the most common viral pathogen. Polymicrobial infections were detected in 32.14% of SES-positive cases. SES elicited a change in the management in 30% of the patients from initial empiric therapy. At discharge, 51 patients recovered fully while 11 patients had partial recovery. Three-month follow-up showed only six patients to have neurological deficits. Conclusion: In a tertiary care center, etiological microbial diagnosis is central to appropriate therapy and outcomes. Sensitive and accurate multiplex molecular diagnostics play a critical role in not only identifying the causative pathogen but also in helping clinicians to institute appropriate therapy, reduce overuse of antimicrobials, and ensure superior clinical outcomes.

In a tertiary care center, etiological microbial diagnosis is central to appropriate therapy and outcomes. Sensitive and accurate multiplex molecular diagnostics play a critical role in not only identifying the causative pathogen but also in helping clinicians to institute appropriate therapy, reduce overuse of antimicrobials, and ensure superior clinical outcomes.

    2005-01-01

    Le soudage de l'aluminium requiert un savoir-faire spécifique pour éviter la formation, dans la soudure, de défauts rédhibitoires tels que les manques de fusion ou soufflures. Ces défauts ont pour causes principales la présence d’une couche d'alumine, une diffusivité thermique élevée et une solubilité très faible de l’hydrogène dans le métal à l’état solide. Les règles de l’art à appliquer pour la préparation des assemblages et pour le choix des paramètres de soudage sont rappelées.

    Full Text Available An increasing body of research provides evidence that socioeconomic status (SES was significantly related to children’s reading development; however, the psychological mechanism underlying the association between them remained an open question. The present study is designed to test the hypothesized three-path effect of vocabulary knowledge and morphological awareness as mediators between SES and sentence reading comprehension in Chinese first-graders. Results of mediation model showed that SES exerted its effect on sentence reading comprehension through the indirect path via the simple mediating effect of morphological awareness and the three-path mediating effect of vocabulary knowledge and morphological awareness. The findings highlight a previously unidentified mechanism of the relationship between SES and reading comprehension in Chinese young children.

    2017-01-01

    This article explores the impact of patient and healthcare provider communication (PPC) on the HIV testing behaviors of middle socioeconomic status (SES) Black women in North Carolina. We explore how PPC about STIs and HIV (or the lack thereof) affects the provision of STI/HIV testing by either confirming the need for middle SES Black women to test routinely or potentially deterring women from feeling they need to be tested. After conducting 15 qualitative interviews with middle SES Black women between 25 and 45 years of age, we uncovered the role of patient self-advocacy in promoting HIV testing among middle SES Black women when they communicate with their healthcare providers. We discuss the importance of healthcare providers engaging their middle SES Black female patients in routine discussions about sexual health and sexual risk reduction, regardless of providers' perceptions of their potential STI/HIV risk. We recommend including SES as a variable in data collection and research in order to better understand how social class, race, and gender affect sexual health behavior and the provision of STI and HIV/AIDS prevention to diverse populations.

  8. “Nobody Sees It, Nobody Gets Mad”: Social Media, Privacy, and Personal Responsibility Among Low-SES Youth

    Directory of Open Access Journals (Sweden)

    Alice Marwick

    2017-05-01

    Full Text Available While few studies examine the online privacy practices or attitudes of young people of low socio-economic status (SES, they are often at the most risk of and most susceptible to privacy violations. This participatory, collaborative study of 28 low-SES young adults in the New York City area investigates how they view online information sharing. Like most Americans, our participants viewed online privacy as an individual responsibility. We make two primary contributions. First, participants revealed extensive awareness of the risks of sharing information online, and many avoided social media, self-censored, or obfuscated their contributions as a result. Second, many participants had extensive experience with policing and physical surveillance and were aware they could not avoid such encounters through their own efforts. This window into structural discrimination provides an alternate frame to that of “individual responsibility” that educators and researchers can use to conceptualize how privacy is violated online. Framing online privacy violations as inevitable and widespread may not only help foster activist anger and strategic resistance but also avoid the victim-blaming narratives of some media literacy efforts. By examining the experiences of these young people, who are often left out of mainstream discussions about privacy, we hope to show how approaches to managing the interplay of on- and offline information flows are related to marginalized social and economic positions.

    2016-10-01

    Socioeconomic status (SES) is a complex construct of multiple indicators, known to impact cancer outcomes, but has not been adequately examined among pediatric AML patients. This study aimed to identify the patterns of co-occurrence of multiple community-level SES indicators and to explore associations between various patterns of these indicators and pediatric AML mortality risk. A nationally representative US sample of 3651 pediatric AML patients, aged 0-19 years at diagnosis was drawn from 17 Surveillance, Epidemiology, and End Results (SEER) database registries created between 1973 and 2012. Factor analysis, cluster analysis, stratified univariable and multivariable Cox proportional hazards models were used. Four SES factors accounting for 87% of the variance in SES indicators were identified: F1) economic/educational disadvantage, less immigration; F2) immigration-related features (foreign-born, language-isolation, crowding), less mobility; F3) housing instability; and, F4) absence of moving. F1 and F3 showed elevated risk of mortality, adjusted hazards ratios (aHR) (95% CI): 1.07(1.02-1.12) and 1.05(1.00-1.10), respectively. Seven SES-defined cluster groups were identified. Cluster 1 (low economic/educational disadvantage, few immigration-related features, and residential-stability) showed the minimum risk of mortality. Compared to Cluster 1, Cluster 3 (high economic/educational disadvantage, high-mobility) and Cluster 6 (moderately-high economic/educational disadvantages, housing-instability and immigration-related features) exhibited substantially greater risk of mortality, aHR(95% CI)=1.19(1.0-1.4) and 1.23 (1.1-1.5), respectively. Factors of correlated SES-indicators and their pattern-based groups demonstrated differential risks in the pediatric AML mortality indicating the need of special public-health attention in areas with economic-educational disadvantages, housing-instability and immigration-related features.

    Full Text Available Disappearance is the loss of a sound in structure of the word with some reasons. There are three types of disappearance: apheresis, syncope and apocope. The apocope is disappearance of a vowel or consonant at the end of a word. This situation isn’t standard in whole dialects and accents. Some dropping sounds, have an intense in a spesific region, they aren’t seen in the other areas or have rare examples. This is rather common in the dialects. In this study will be handled the apocope in the loan words with the examples in Turkey Turkish and contemporary Turkish dialects.

    Full Text Available De acordo com o Banco Mundial, desde o final dos anos 2000 o movimento de aquisição de terras por estrangeiros tem se acentuado nos países em desenvolvimento, impulsionado pelo boom dos preços das commodities. Em termos teóricos, a abordagem da Nova Economia Institucional (NEI argumenta que as instituições são importantes para as estratégias dos agentes econômicos e seu desempenho. Neste estudo, apoiado na NEI, pretende-se responder como as instituições presentes em países periféricos refletem o processo de aquisições de terras por investidores estrangeiros. Para esse objetivo, foram utilizados dados secundários de organizações internacionais, como Food and Agriculture Organization, Banco Mundial, Conferência das Nações Unidas sobre Comércio e Desenvolvimento, Fundo Monetário Internacional, Organização para a Cooperação Econômica e Desenvolvimento Econômico, Wall Street Journal e agências nacionais. A hipótese principal é que a força ou a fraqueza presente no ambiente institucional em países em desenvolvimento tem influência relevante no nível de Investimento Estrangeiro Direto (IED.

  16. Momentary smoking context as a mediator of the relationship between SES and smoking.

    Jahnel, Tina; Ferguson, Stuart G; Shiffman, Saul; Thrul, Johannes; Schüz, Benjamin

    2018-08-01

    There is a well-established socioeconomic gradient in smoking behavior: those with lower socioeconomic status smoke more. However, much less is known about the mechanisms explaining how SES is linked to smoking. This study takes a social-ecological perspective by examining whether socioeconomic status affects smoking behavior by differential exposure to places where smoking is allowed. Exposure to smoking restrictions was assessed in real-time using Ecological Momentary Assessment methods. A sample of 194 daily smokers, who were not attempting to quit, recorded their smoking and information about situational and contextual factors for three weeks using an electronic diary. We tested whether a smoker's momentary context mediated the relationship between socioeconomic status (educational attainment) and cigarettes smoked per day (CPD). Momentary context was operationalized as the proportion of random assessments answered in locations where smoking was allowed versus where smoking was not allowed. Data were analysed using multilevel regression (measurements nested within participants) with a lower level mediation model (2-1-1 mediation). Although no significant direct effect of SES on CPD were observed, there was a significant indirect effect of SES on CPD via the momentary context. Compared to participants with higher education, lower educated participants were more likely to encounter places where smoking was allowed, and this in turn, was associated with a higher number of CPD. These findings suggest that SES is associated with smoking at least partially via differential exposure to smoking-friendly environments, with smokers from lower SES backgrounds accessing more places where smoking is allowed. Implications for current smoke-free legislation are discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

  1. Temporal dependence of the selectivity property of SES stations in western Greece

    Directory of Open Access Journals (Sweden)

    2009-06-01

    Full Text Available The selectivity property of the SES stations, IOA, PIR and PAT in western Greece, based on reported precursory SES signals and associated large earthquakes (Mw≥5.4 that occurred from 1983 to the end of 2008, has been examined. Interesting temporal dependence of the sensitive ability of these stations has been unveiled. Physical mechanisms for the observed changes in selectivity might be related with tectonic and geodynamic events. For instance, selectivity for IOA exhibits a time dependence, for PAT probably is related to the activation of Wadati-Benioff zone while for PIR seems to be related to the specific tectonics of two confined areas such as the Cephalonia Transform Faulting zone in Ionian Sea and the southwestern part of the Hellenic Trench.

    This study examined the effects of the verbal labels procedure and vocabulary skills on low-socioeconomic status (SES) preschool children's eyewitness memory. Children (N = 176) aged 3-5 years witnessed a conflict event and were then questioned about it in either a standard or a verbal labels interview. Findings revealed that children with higher rather than lower vocabulary skills produced more complete and accurate memories. Children who were given the verbal labels interview recalled more information, which included both correct and incorrect details. Overall, the verbal labels procedure did not improve children's performance on direct questions, but children with low vocabulary skills answered direct questions more accurately if they were given the verbal labels interview than when they were not. Implications of the findings for memory performance of low-SES children are discussed. Copyright © 2014 John Wiley & Sons, Ltd.

    2010-01-01

    The present study examined the relevance of communalism, operationalized as a cultural orientation emphasizing interdependence, to maternal prenatal emotional health and physiology and distinguished its effects from those of ethnicity and childhood and adult SES. African American and European American women (N=297) were recruited early in pregnancy and followed through 32 weeks gestation using interviews and medical chart review. Overall, African American women and women of lower socioeconomic backgrounds had higher levels of negative affect, stress and blood pressure, but these ethnic and socioeconomic disparities were not observed among women higher in communalism. Hierarchical multivariate regression analyses showed that communalism was a more robust predictor of prenatal emotional health than ethnicity, childhood SES, and adult SES. Communalism also interacted with ethnicity and SES, resulting in lower blood pressure during pregnancy for African American women and women who experienced socioeconomic disadvantage over the life course. The effects of communalism on prenatal affect, stress, and physiology were not explained by depressive symptoms at study entry, perceived availability of social support, self-esteem, optimism, mastery, nor pregnancy-specific factors, including whether the pregnancy was planned, desired after conception, or how frequently the woman felt happy to be pregnant. This suggests that a communal cultural orientation benefits maternal prenatal emotional health and physiology over and above its links to better-understood personal and social resources in addition to economic resources. Implications regarding culture as a determinant of maternal prenatal health and well-being and as a potentially important lens for examining ethnic and socioeconomic inequalities in health are discussed.

    Full Text Available Tournant le dos aux interprétations nationalistes indiennes et pakistanaises, cet article restitue la dimension millénariste de la carrière de Sayyid Ahmad Barelwî (1786-1831. Ce soufi naqshbandi, qui fut successivement soldat de fortune et réformateur religieux, lança en 1826 un jihâd contre les Sikhs et contre la présence britannique en Inde. Il disparut mystérieusement lors d'une bataille, et ses disciples attendirent son retour comme mahdi pendant plus d'un demi-siècle. Cette ultime arrière messianique est interprétée en quatre étapes. Je montre d'abord comment le contexte politique et social favorisait le développement d'idées millénaristes. La mentalité religieuse de l'époque et la place qu'y occupait l'eschatologie sont ensuite étudiées. La carrière posthume de Sayyid Ahmad comme mahdi est ensuite restituée à travers les sources coloniales. Enfin l'examen de documents originaux en persan écrit avant la mort de Sayyid Ahmad corrigera cette image coloniale, tout en montrant que, déjà de son vivant, il était bien perçu par ses disciples comme une sorte de mahdi du milieu des temps, analogue à certains égards au mujaddid tek que le concevaient les Naqshbandis.

    2013-02-01

    This study examined the ways in which body mass index (BMI) percentile - an identified risk factor for overweight and cardiovascular disease in adulthood - develops from birth through early adolescence. In addition, we examined whether psychosocial factors, such as parenting style and maternal depression, mediated the link between socio-economic status (SES) and BMI growth. Design. Data were obtained from phases 1-3 of the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care and Youth Development (SECCYD) - a longitudinal study that followed children from 10 communities in the United States from birth to age 11. We applied growth mixture models to identify distinct subtypes of BMI development. Within these models, we performed between- and within-class mediation analyses to examine whether SES predicted class membership or differences in development within each class via maternal depression and parenting styles. Results identified three prototypic trajectories of BMI percentile growth, elevated, steady increase, and stable. We found evidence for both between- and within-class mediation, suggesting multiple pathways by which SES can affect BMI development. These findings add to the research that suggests that being in a family with a low SES is associated with falling into patterns of development characterized by early and lasting increases in BMI relative to one's peers, and that this association is partly accounted for by maternal depression and parenting styles. What is already known? Past research has found evidence that patterns of childhood overweight are impacted by socioeconomic status through psychosocial factors like parenting and depression. This evidence is often limited to individual points in time where neglectful, permissive, and authoritarian parenting and higher levels of maternal depression are associated with higher levels of overweight status among children from infancy to adolescence. However, little

    The current study explores the influence of socioeconomic status (SES) and bilingualism on the linguistic skills and verbal short-term memory of preschool children. In previous studies comparing children of low and mid-high SES, the terms "a child with low-SES" and "a child speaking a minority language" are often interchangeable, not enabling differentiated evaluation of these two variables. The present study controls for this confluence by testing children born and residing in the same country and attending the same kindergartens, with all bilingual children speaking the same heritage language (HL-Russian). A total of 120 children (88 bilingual children: 44 with low SES; and 32 monolingual children: 16 with low SES) with typical language development, aged 5; 7-6; 7, were tested in the societal language (SL-Hebrew) on expressive vocabulary and three repetition tasks [forward digit span (FWD), nonword repetition (NWR), and sentence repetition (SRep)], which tap into verbal short-term memory. The results indicated that SES and bilingualism impact different child abilities. Bilingualism is associated with decreased vocabulary size and lower performance on verbal short-term memory tasks with higher linguistic load in the SL-Hebrew. The negative effect of bilingualism on verbal short-term memory disappears once vocabulary is accounted for. SES influences not only linguistic performance, but also verbal short-term memory with lowest linguistic load. The negative effect of SES cannot be solely attributed to lower vocabulary scores, suggesting that an unprivileged background has a negative impact on children's cognitive development beyond a linguistic disadvantage. The results have important clinical implications and call for more research exploring the varied impact of language and life experience on children's linguistic and cognitive skills.

    Objectives Children in families of low socioeconomic status (SES) have been found to have poor sleep, yet the reasons for this finding are unclear. Two possible mediators, presleep worries and home environment conditions, were investigated as indirect pathways between SES and children’s sleep. Participants/Methods The participants consisted of 271 children (M (age) = 11.33 years; standard deviation (SD) = 7.74 months) from families varying in SES as indexed by the income-to-needs ratio. Sleep was assessed with actigraphy (sleep minutes, night waking duration, and variability in sleep schedule) and child self-reported sleep/wake problems (e.g., oversleeping and trouble falling asleep) and sleepiness (e.g., sleeping in class and falling asleep while doing homework). Presleep worries and home environment conditions were assessed with questionnaires. Results Lower SES was associated with more subjective sleep/wake problems and daytime sleepiness, and increased exposure to disruptive sleep conditions and greater presleep worries were mediators of these associations. In addition, environmental conditions served as an intervening variable linking SES to variability in an actigraphy-derived sleep schedule, and, similarly, presleep worry was an intervening variable linking SES to actigraphy-based night waking duration. Across sleep parameters, the model explained 5–29% of variance. Conclusions Sleep environment and psychological factors are associated with socioeconomic disparities, which affect children’s sleep.

    Socioeconomic risks (SES risks) are robust risk factors influencing children's academic development. However, it is unclear whether the effects of SES on academic development operate universally in all children equally or whether they vary differentially in children with particular characteristics. The current study aimed to explore children's temperament as protective or risk factors that potentially moderate the associations between SES risks and academic development. Specifically, latent growth modeling (LGM) was used in two longitudinal datasets with a total of 2236 children to examine how family SES risks and children's temperament interactively predicted the development of reading and math from middle childhood to early adolescence. Results showed that low negative affect, high effortful control, and low surgency mitigated the negative associations between SES risks and both reading and math development in this developmental period. These findings underline the heterogeneous nature of the negative associations between SES risks and academic development and highlight the importance of the interplay between biological and social factors on individual differences in development. © 2015 John Wiley & Sons Ltd.

    To compare the clinical outcome of a multiplex polymerase chain reaction (PCR) based molecular diagnostic method -- Syndrome Evaluation System (SES) directed treatment strategy vs. standard of care (blood culture) directed treatment strategy for neonatal sepsis. This randomized controlled trial (RCT) included 385 neonates with sepsis who were randomized into two groups -- SES and control (BACTEC). Both tests were performed for all the neonates. However, in the SES group, the results of SES test were revealed to the treating clinicians, while in the control group, SES results were withheld. Two ml of blood was drawn from each baby. One aliquot was sent for blood culture, whereas the remaining aliquot was sent for SES. Babies were then administered empirical IV antibiotics and given supportive care. Further antibiotic changes, if required were done in SES and control groups based on their respective reports. The microbiological profile, immediate outcome, duration of hospital stay, number of antibiotics used and readmission within a month in both groups were compared. SES was better than BACTEC in identifying the causative organism in both the groups (68 % vs. 18 % in SES group and 72 % vs. 18 % in control group). SES had 100 % concordance with blood culture by BACTEC. Detection of bacteria and fungi were four and ten-fold higher respectively with SES when compared to BACTEC culture. Microbiological diagnosis was rapid with SES compared to BACTEC (7 h vs. 72 h). Treatment based on SES resulted in significantly less mortality (3 % vs. 18 %). Readmission rate, duration of hospital stay and change in antibiotics were also significantly less in SES group. This new molecular based diagnostic system (SES) helps in rapid and accurate diagnosis of neonatal sepsis and reduces mortality and morbidity in affected neonates.

    The 3-SES-149A well, at a water depth of 1164 meters, is part of the SEAL-100 block located offshore of the State of Sergipe. The objective of the intervention was to evaluate the 3674-3682 meters interval of the Riachuelo Formation. Bottom hole gauges and real time data transmission to the surface were deployed for this test, during which the target interval produced gas and condensate, without any evidence of formation of hydrate at the surface. After the test, while pulling out the electrical cable with the Link Running Tool, it got stuck close to the subsea well-test tree at a depth of 1257 meters. The formation of hydrate not only kept the cable from moving up, but also rendered impossible the reverse circulation in the column and consequently pulling out the test string. Removing the hydrate would allow releasing the logging cable, thus enabling fluid circulation in the string and its safe retrieval. The goal was achieved via the injection of solvent through the subsea well-test tree, drilling fluid circulation through the annulus above the BOP, and fluid circulation on the top of the hydrate plug through Coiled Tubing. The greatest challenge was running the Coiled Tubing in the string with the electrical cable inside. (author)

    Full Text Available El presente trabajo tiene como objetivo describir tendencias a partir de algunos indicadores de calidad de vida en el conjunto de países de dependencia mineral. A partir de gráficos Box-Plot e índices de correlación, se procedió a la descripción de tendencias estadísticas para realizar precisiones en torno a la calidad de vida -analizada a través del índice de desarrollo humano [ÍDH] y componentes- y variables económicas [exportaciones minerales como porcentaje del total de exportaciones y del producto interno bruto] y demográficas [fecundidad, mortalidad infantil]. Aunque no se precisó alguna correlación estadística entre el porcentaje de exportaciones minerales como parte del PIB con el ÍDH o alguno de sus componentes, se encontró relación significativa con el porcentaje como parte del total de exportaciones aunque -en su relación con el IDH y con el índice de logro educativo- sólo había relaciones inversas de carácter leve. En relación con las variables demográficas, sólo se encontró relaciones leves entre el porcentaje de exportaciones minerales sobre exportaciones totales con la tasa de fecundidad total y la tasa de mortalidad infantil, sin que se haya encontrado alguna significatividad en la tasa de mortalidad de niños menores de 5 años. Se precisó que, aunque la mayor parte de los países con dependencia mineral poseen valores ÍDH medio, los valores reflejan fuertes diferencias regionales, distribuciones asimétricas positivas matizadas en lo referente a las exportaciones minerales y dispersión desigual de los valores ÍDH, siendo mayor entre los países de alta dependencia mineral.

El artículo analiza los avances obtenidos por los países en desarrollo en las negociaciones de la Ronda de Doha en dos temas centrales del debate mundial sobre propiedad intelectual: los productos farmacéuticos y el conocimiento tradicional, y deja abierto el debate sobre el retroceso que el auge de la vía bilateral podría significar para la defensa de sus intereses. El objetivo de este artículo es evidenciar que a pesar de que los plazos previstos para finalizar la Ronda de Doha se han incumplido, el plazo inicial era el 1o de enero de 2005 y en diciembre de 2005 los miembros se propusieron extraoficialmente concluir las negociaciones a finales de 2006 –plazo que tampoco se cumplió– y que hasta ahora sólo puede ser calificada de fracaso –el bloqueo de las negociaciones obligaron a su suspensión indefinida en julio de 2006–, no debe desconocerse que, en lo que al Acuerdo sobre los ADPIC se refiere, permitió que los países en desarrollo iniciaran una ofensiva que no podrían haber contemplado veinte años atrás. Así, gracias al carácter multilateral de la OMC que tantas críticas ha despertado, en los países desarrollados han logrado defender sus intereses en un tema de vital importancia para sus reivindicaciones como es el del acceso a medicamentos y han abierto el debate para que finalmente se reconozca el derecho que tienen de proteger y beneficiarse de los conocimientos tradicionales.

    To evaluate the association between dental caries experience and preventive behaviours of children residing in a deprived area in Clermont-Ferrand (France). All 4-5 yr-olds attending nine schools in deprived areas of the city were invited to participate and 81% (n=282) consented and were examined. Dental caries was recorded at the dentine threshold. Parents completed a questionnaire concerning family demographics and the child's use of fluoride. Non-parametric tests and logistic regression assessed the relative importance of SES and fluoride variables on dental status (dt>1). Fifty four (19%) of the examined children were living in families with an immigrant background, 33% were fully covered by the national health insurance programme for deprived families. Caries experience was high; mean dft was 1.94 (3.31) and 30% of the children had >1 carious teeth. Thirty percent of the families reported using fluoridated salt. Tooth brushing once daily was reported for 39% and twice daily for 26%. Parents declared supervising tooth brushing for 60%. Two thirds of the children, according to their parents, used fluoride supplement between birth and two years. Supervised tooth brushing was significantly correlated with lower mean dt scores. Systemic fluoride use was poorly related to dental caries Immigrant background, family size, type of health insurance and mother's unemployment were significantly correlated with caries prevalence. In multivariate analysis, immigrant status, supervised tooth brushing and parental knowledge about fluoride in toothpastes were significant caries predictors. The majority of low SES children did not practice effective caries prevention; few reported twice daily brushing with fluoride toothpaste. Caries experience was very high and much was untreated. Immigrant status, supervised tooth brushing and parental knowledge about fluoride in toothpastes were significant caries predictors.

    Youth with Type 1 diabetes (T1D) from single-parent families have poorer glycemic control; a finding confounded with socioeconomic status (SES). Family density (FD), or youth:adult ratio, may better characterize family risk status. Structural equation modeling assessed the relation of single-parent status, SES, and FD to parenting stress, diabetes-related conflict, parental monitoring, adherence, and glycemic control using cross-sectional parent and youth data (n = 257). Single-parent status exhibited similar relations as SES and was removed. Lower FD was associated with better glycemic control (β = -.29, p = .014) via less conflict (β = .17, p = .038) and greater adherence (β = -.54, p single-parent status were indistinguishable from those of SES. FD provides distinct information related to adolescent glycemic control. © The Author 2015. Published by Oxford University Press on behalf of the Society of Pediatric Psychology. All rights reserved.

  18. Early-life Socio-economic Status and Adult Health: The Role of Positive Affect.

    Murdock, Kyle W; LeRoy, Angie S; Fagundes, Christopher P

    2017-08-01

    The aim of this paper is to develop a further understanding of the relationship between early-life socio-economic status (SES) and adult health disparities. This was accomplished through evaluation of state indicators of positive and negative affect as mechanisms through which early-life SES was associated with susceptibility to a rhinovirus (i.e. the common cold). Analyses were conducted among 286 adults in a viral challenge study in which participants were exposed to a rhinovirus via nasal drops and cold symptoms were evaluated over a period of 5 days. Participant age, body mass index, sex, education, ethnicity, pre-challenge virus-specific antibody titres and subjective adult SES, along with virus type and season of participation, were included as covariates. Early-life SES was associated with cold incidence through state positive affect, but not state negative affect. In addition, contrast analysis indicated that the indirect effect through state positive affect was stronger than the indirect effect through state negative affect. Findings provide further support for early-life SES being an important variable associated with adult health, and that state self-reported positive affect may be an underlying mechanism associated with susceptibility to rhinoviruses.

    The ability to adaptively inhibit responses to tempting/distracting stimuli in the pursuit of goals is an essential set of skills necessary for adult competence and wellbeing. These inhibitory capacities develop throughout childhood, with growing evidence of important maturational changes occurring in adolescence. There also has been intense interest in the role of social adversity on the development of executive function, including inhibitory control. We hypothesized that the onset of adolescence could be a time of particular opportunity/vulnerability in the development of inhibition due to the large degree of maturational changes in neural systems involved in regulatory control. We investigated this hypothesis in a longitudinal study of adolescents by examining the impact of socioeconomic status (SES) on the maturation of inhibition and concurrent brain function. Furthermore, we examined gender as a potential moderator of this relationship, given evidence of gender-specificity in the developmental pathways of inhibition as well as sex differences in adolescent development. Results reveal that lower SES is associated with worse behavioral inhibition over time and a concurrent increase in anterior cingulate (ACC) activation, but only in girls. We also found that lower SES girls exhibited decreased ACC ↔ dorsolateral prefrontal cortex (dlPFC) coupling over time. Our findings suggest that female adolescents with lower SES appear to develop less efficient inhibitory processing in dlPFC, requiring greater and relatively unsuccessful compensatory recruitment of ACC. In summary, the present study provides a novel window into the neural mechanisms by which the influence of SES on inhibition may be transmitted during adolescence. © 2015 Wiley Periodicals, Inc.

    Full Text Available El objetivo de este documento es determinar los canales de transmisión de la crisis europea hacia los países del Tercer Mundo. El trabajo examina la forma en que la crisis de la deuda soberana se propagó por el sector financiero, a través de la mayor volatilidad de la rentabilidad de los activos. Lo cual se debió a una mayor variación de sus precios, lo que tuvo efectos sobre el patrimonio neto de los agentes económicos, los ingresos, la demanda agregada y la asignación del crédito, así como también sobre la producción y el empleo. Para este documento se hizo búsqueda y selección de literatura especializada y se extrajeron estadísticas especializadas de la UNCTAD, CEPAL y OECD. Se concluye que la transmisión de la crisis europea al Tercer Mundo se dio por canales específicos conocidos, como el comercio internacional, la inversión extranjera directa, las remesas y la ayuda oficial para el desarrollo.

  9. Hospital daily outpatient visits forecasting using a combinatorial model based on ARIMA and SES models.

    Science.gov (United States)

    Luo, Li; Luo, Le; Zhang, Xinli; He, Xiaoli

    2017-07-10

    Accurate forecasting of hospital outpatient visits is beneficial for the reasonable planning and allocation of healthcare resource to meet the medical demands. In terms of the multiple attributes of daily outpatient visits, such as randomness, cyclicity and trend, time series methods, ARIMA, can be a good choice for outpatient visits forecasting. On the other hand, the hospital outpatient visits are also affected by the doctors' scheduling and the effects are not pure random. Thinking about the impure specialty, this paper presents a new forecasting model that takes cyclicity and the day of the week effect into consideration. We formulate a seasonal ARIMA (SARIMA) model on a daily time series and then a single exponential smoothing (SES) model on the day of the week time series, and finally establish a combinatorial model by modifying them. The models are applied to 1 year of daily visits data of urban outpatients in two internal medicine departments of a large hospital in Chengdu, for forecasting the daily outpatient visits about 1 week ahead. The proposed model is applied to forecast the cross-sectional data for 7 consecutive days of daily outpatient visits over an 8-weeks period based on 43 weeks of observation data during 1 year. The results show that the two single traditional models and the combinatorial model are simplicity of implementation and low computational intensiveness, whilst being appropriate for short-term forecast horizons. Furthermore, the combinatorial model can capture the comprehensive features of the time series data better. Combinatorial model can achieve better prediction performance than the single model, with lower residuals variance and small mean of residual errors which needs to be optimized deeply on the next research step.

Un desarrollo que se concibe como equitativo en lo social, sostenible en lo económico y sustentable en lo ecológico. El argumento central de este trabajo es que la inserción internacional de los países permite distinguir entre aquellos que han logrado conformar procesos de autonomía y los que han generado inserciones dependientes. Entre estos últimos –donde se ubican los latinoamericanos- se pueden distinguir países que son sociedades más funcionales, de aquellos cuya disfuncionalidad social es muy evidente. La referencia conceptual fundamental se basa por lo general, en los postulados que sobre desarrollo humano ha elaborado la Organización de Naciones Unidas, desde la publicación del primer Informe Mundial de Desarrollo en 1992.

    Full Text Available Abstract Background Recruitment, willingness to participate, and retention in interventions are indispensable for successful prevention. This study investigated the effectiveness of different strategies for recruiting and retaining low-SES women in depression prevention, and explored which sociodemographic characteristics and risk status factors within this specific target group are associated with successful recruitment and retention. Methods The process of recruitment, willingness to participate, and retention was structurally mapped and explored. Differences between women who dropped out and those who adhered to the subsequent stages of the recruitment and retention process were investigated. The potential of several referral strategies was also studied, with specific attention paid to the use of GP databases. Results As part of the recruitment process, 12.1% of the target population completed a telephone screening. The most successful referral strategy was the use of patient databases from GPs working in disadvantaged neighborhoods. Older age and more severe complaints were particularly associated with greater willingness to participate and with retention. Conclusions Low-SES women can be recruited and retained in public health interventions through tailored strategies. The integration of mental health screening within primary care might help to embed preventive interventions in low-SES communities.

    This text serves as a thorough introduction to the rapidly developing field of positional games. This area constitutes an important branch of combinatorics, whose aim it is to systematically develop an extensive mathematical basis for a variety of two-player perfect information games. These range from such popular games as Tic-Tac-Toe and Hex to purely abstract games played on graphs and hypergraphs. The subject of positional games is strongly related to several other branches of combinatorics such as Ramsey theory, extremal graph and set theory, and the probabilistic method. These notes cover a variety of topics in positional games, including both classical results and recent important developments. They are presented in an accessible way and are accompanied by exercises of varying difficulty, helping the reader to better understand the theory. The text will benefit both researchers and graduate students in combinatorics and adjacent fields.

    Asset-based approaches have become popular in public health. As yet it is not known to what extent health and welfare professionals are able to identify and mobilise individual and community health assets. Therefore, the aim of this study was to understand professional's perceptions of health and health assets. In a low-SES neighbourhood, 21 health and welfare professionals were interviewed about their definition of health and their perceptions of the residents' health status, assets available in the neighbourhood's environment, and the way residents use these assets. A Nominal Group Technique (NGT) session was conducted for member check. Verbatim transcripts of the semi-structured interviews were coded and analysed using Atlas.ti. The professionals used a broad health concept, emphasizing the social dimension of health as most important. They discussed the poor health of residents, mentioning multiple health problems and unmet health needs. They provided many examples of behaviour that they considered unhealthy, in particular unhealthy diet and lack of exercise. Professionals considered the green physical environment, as well as health and social services, including their own services, as important health enhancing factors, whereas social and economic factors were considered as major barriers for good health. Poor housing and litter in public space were considered as barriers as well. According to the professionals, residents underutilized neighbourhood health assets. They emphasised the impact of poverty on the residents and their health. Moreover, they felt that residents were lacking individual capabilities to lead a healthy life. Although committed to the wellbeing of the residents, some professionals seemed almost discouraged by the (perceived) situation. They looked for practical solutions by developing group-based approaches and supporting residents' self-organisation. Our study shows, firstly, that professionals in the priority district Slotermeer rated

O modelo de equilíbrio geral aplicado do Projeto de Análise de Comércio Global (Gtap é usado para implementar as simulações. Os resultados sugerem que a Alca traz aumentos na produção agrícola e superávits comerciais nos países do Mercosul; no entanto, para os produtos manufaturados tais efeitos são negativos. Os EUA e o Canadá apresentam uma pequena redução na balança comercial. O Brasil é o único país do Mercosul com ganhos de bem-estar. Os efeitos do Mercoeuro sobre os países membros são similares aos da Alca, porém em maior magnitude. Os ganhos de bem-estar estão presentes para todos os países do Mercoeuro, sendo este acordo mais favorável para os países do Mercosul do que a Alca.The objective of this paper is to determine the impacts on the international agricultural market of potential trade liberalization agreements such as Americas Free Trade Area (Afta and Mercosul and European Union Free Trade Area (Mercoeuro. The general equilibrium model from the Global Trade Analysis Project (Gtap is applied to run the simulations. The results suggest that Afta increases agricultural production and trade balance for the Mercosul countries, but for manufactures the effects are negative on both production and trade balance. The U.S. and Canada show a small reduction on trade balance. Brazil is the only Mercosul country to obtain welfare gains with Afta. The impacts of Mercoeuro on its member country are similar to those of Afta, but they are greater in magnitude. Also, all countries have welfare gains in the Mercoeuro, which presents greater benefits than Afta to their respective.

    Purpose: To enable to detect the position of an moving object in a control rod position detector, stably in a digital manner at a high accuracy and free from the undesired effects of circumstantial conditions such as the reactor temperature. Constitution: Coils connected in parallel with each other are disposed along the passage of a moving object and variable resistors and relays are connected in series with each of the coils respectively. Light emitting diodes is connected in series with the contacts of the respective relays. The resistance value of the variable resistors are adjusted depending on the changes in the circumstantial conditions and temperature distribution upon carrying out the positional detection. When the object is inserted into a coils, the relevant relay is deenergized, by which the relay contacts are closed to light up the diode. In the same manner, as the object is successively inserted into the coils, the diodes are lighted-up successively thereby enabling highly accurate and stable positional detection in a digital manner, free from the undesired effects of the circumstantial conditions.

    Emotive anti-tobacco advertisements can increase quitting. Discrete emotion theories suggest evoking fear may be more effective than sadness; less research has focused on hope. A weekly cross-sectional survey of smokers and recent quitters (N = 7683) measured past-month quit attempts. The main predictor was level of exposure to four different types of anti-tobacco advertisements broadcast in the two months prior to quit attempts: advertisements predominantly evoking fear, sadness, hope, or evoking multiple negative emotions (i.e., fear, guilt, and/or sadness). Greater exposure to fear-evoking advertisements (OR = 2.16, p < .01) increased odds of making a quit attempt and showed similar effectiveness among those in lower and higher SES areas. Greater exposure to advertisements evoking multiple negative emotions increased quit attempts (OR = 1.70, p < .01), but interactions indicated this was driven by those in lower SES, but not higher SES areas. Greater exposure to hope-evoking advertisements enhanced effects of fear-evoking advertisements among those in higher SES, but not lower SES areas. Findings suggest to be maximally effective across the whole population avoid messages evoking sadness and use messages eliciting fear. If the aim is to specifically motivate those living in lower SES areas where smoking rates are higher, multiple negative emotion messages, but not hope-evoking messages, may also be effective.

Mientras tanto, 10% de la población disfruta del 70% de riquezas. Proliferan estallidos sociales, guerras, huracanes, terremotos, contaminación ambiental, inundaciones, calentamiento global, SIDA. Numerosas comunidades rurales se han colapsado económica y socialmente, el desempleo aumenta por tecnologías ahorradoras de fuerza laboral, persiste alta migración a las ciudades. La “Revolución Verde”, de especialización e industrialización agropecuaria de países desarrollados, ha generado conflictos ambientales y no ha sido una solución. La geofagia y sed de poder de países y políticos, generan distribución desequilibrada de riquezas. En nuestro planeta abundan resultados positivos con sistemas agroecológicos de producción que han demostrado poder resolver gran número de esos problemas. En América Latina y Cuba, existen experiencias del saber y tradiciones campesinas e indígenas, investigación y producción comercial con soluciones factibles para los problemas de este llamado “Tercer Mundo”, donde están los países más necesitados. Son evidentes los caminos posibles para alcanzar el anhelado desarrollo agropecuario. Este trabajo resume algunos ejemplos de los avances. El reto futuro es integrar los componentes de los agroecosistemas y lograr sinergias, consolidando sistemas agroecológicos holísticos, con eficiencia biológica, productiva, económica, energética y ambiental. Es esperanzador pensar que un futuro agroecológico unido a la voluntad política de desarrollo económico y social, puede contribuir en alto grado a liberar a nuestros países tercermundistas de la crítica situación actual

    Hip replacement is used for inoperable femur head injuries and femur fractures where internal fixation can not be used. This operation is one of the most common orthopedic operations that many research have been done about it. Among these we can mention implant and cement materials and composites optimization and also implant shape optimization. This study was designed to optimize artificial hip joint position (placement) to decrease maximal von mi sees stress. First, a model of femur and implant were made and then a computer program was written with the ability to change the position of implant through an acceptable range in the femur. In each of these positions, the program simulated femur and implant according to finite element method and made, applied forces were weight and muscle traction. Our findings show that a small deviation of the implant from femur bone center causes a considerable decrease in von mi sees stress that consequently results in longer maintenance of the implant

    Full Text Available Resumo O processo de fragmentação da produção tem imprimido novas formas de organização da produção e de comércio entre os países. Dentre os diversos fatores explicativos dessa reorganização das atividades produtivas, aqueles relativos aos custos de comércio são de particular importância. Nesse sentido, os acordos comerciais podem ter uma influência relevante na formação de redes produtivas regionais e, mesmo, globais. Este artigo busca investigar se os acordos firmados no âmbito da Aladi contribuíram para aprofundar a integração produtiva na região, por meio da análise do perfil do comércio regional e da estimação de um modelo gravitacional. O grau de integração dos países da região nas redes produtivas internacionais e regionais é bem inferior aquele observado na Ásia, na América do Norte e na Europa. No entanto, as estimações sugerem que os acordos da Aladi exerceram uma influência fraca, porém, positiva sobre os fluxos regionais de partes, componentes e bens de capital.

Participating institutions from outside the region in intra-regional co-authorship were most commonly European (40% of cases and North American (38%. The impact of papers as measured by a normalized h-index, involving scientists from outside the region was greater than that found for all intra-regional publications. The dominant bilateral regional collaboration was between Brazil and Argentina which in recent years has focused on topics in the Health Sciences and Astronomy. A detailed analysis of Physics papers showed that institutions from Brazil and Argentina are the most productive in intra-regional collaborations and Condensed Matter, the most studied subject.

    The current study explores the influence of socioeconomic status (SES) and bilingualism on the linguistic skills and verbal short-term memory of preschool children. In previous studies comparing children of low and mid-high SES, the terms “a child with low-SES” and “a child speaking a minority language” are often interchangeable, not enabling differentiated evaluation of these two variables. The present study controls for this confluence by testing children born and residing in the same country and attending the same kindergartens, with all bilingual children speaking the same heritage language (HL-Russian). A total of 120 children (88 bilingual children: 44 with low SES; and 32 monolingual children: 16 with low SES) with typical language development, aged 5; 7–6; 7, were tested in the societal language (SL-Hebrew) on expressive vocabulary and three repetition tasks [forward digit span (FWD), nonword repetition (NWR), and sentence repetition (SRep)], which tap into verbal short-term memory. The results indicated that SES and bilingualism impact different child abilities. Bilingualism is associated with decreased vocabulary size and lower performance on verbal short-term memory tasks with higher linguistic load in the SL-Hebrew. The negative effect of bilingualism on verbal short-term memory disappears once vocabulary is accounted for. SES influences not only linguistic performance, but also verbal short-term memory with lowest linguistic load. The negative effect of SES cannot be solely attributed to lower vocabulary scores, suggesting that an unprivileged background has a negative impact on children’s cognitive development beyond a linguistic disadvantage. The results have important clinical implications and call for more research exploring the varied impact of language and life experience on children’s linguistic and cognitive skills. PMID:28890706

    This study examines how the intersecting consequences of race-ethnicity, gender, socioeconomics status (SES), and age influence health inequality. We draw on multiple-hierarchy stratification and life course perspectives to address two main research questions. First, does racial-ethnic stratification of health vary by gender and/or SES? More specifically, are the joint health consequences of racial-ethnic, gender, and socioeconomic stratification additive or multiplicative? Second, does this combined inequality in health decrease, remain stable, or increase between middle and late life? We use panel data from the Health and Retirement Study (N = 12,976) to investigate between- and within-group differences in in self-rated health among whites, blacks, and Mexican Americans. Findings indicate that the effects of racial-ethnic, gender, and SES stratification are interactive, resulting in the greatest racial-ethnic inequalities in health among women and those with higher levels of SES. Furthermore, racial-ethnic/gender/SES inequalities in health tend to decline with age. These results are broadly consistent with intersectionality and aging-as-leveler hypotheses. © American Sociological Association 2016.

    Full Text Available The aim of this study was to examine the relationships among vocabulary knowledge, phonological representations and phonological sensitivity in 80 Spanish-speaking preschool children from middle- and low-SES families. Significant social class differences were obtained on all tasks except syllable matching. Regression analyses were carried out to test the predictive power of vocabulary knowledge and accuracy of phonological representations on the phonological sensitivity measures. Receptive vocabulary predicted rhyme identification. Syllable matching was predicted by a task tapping accuracy of phonological representations. The fact that rhyme identification was predicted by vocabulary knowledge but syllable matching was predicted by a measure tapping accuracy of phonological representations in both groups suggests that early lexical development sets the stage for the development of the lower levels of phonological sensitivity but identification of smaller units requires more accurate and segmented phonological representations.

    Very few studies have examined predictors of suicidal ideation among African American women. Consequently, we have a poor understanding of the combinations of culturally-specific experiences and psychosocial processes that may constitute risk and protective factors for suicide in this population. Drawing on theories of social inequality, medical sociology, and the stress process, we explore the adverse impact of gendered racism experiences and potential moderating factors in a sample of 204 predominantly low-SES African American women. We find that African American women’s risk for suicidal ideation is linked to stressors occurring as a function of their distinct social location at the intersection of gender and race. In addition, we find that gendered racism has no effect on suicidal ideation among women with moderate levels of well-being, self-esteem, and active coping, but has a strong adverse influence in those with high and low levels of psychosocial resources.

  6. SES Gradients Among Mexicans in the United States and in Mexico: A New Twist to the Hispanic Paradox?

    Recent empirical findings have suggested the existence of a twist in the Hispanic paradox, in which Mexican and other Hispanic foreign-born migrants living in the United States experience shallower socioeconomic status (SES) health disparities than those in the U.S. In this article, we seek to replicate this finding and test conjectures that could explain this new observed phenomenon using objective indicators of adult health by educational attainment in several groups: (1) Mexican-born individuals living in Mexico and in the United States, (2) U.S.-born Mexican Americans, and (3) non-Hispanic American whites. Our analytical strategy improves upon previous research on three fronts. First, we derive four hypotheses from a general framework that has also been used to explain the standard Hispanic paradox. Second, we study biomarkers rather than self-reported health and related conditions. Third, we use a binational data platform that includes both Mexicans living in Mexico (Mexican National Health and Nutrition Survey 2006) and Mexican migrants to the United States (NHANES 1999-2010). We find steep education gradients among Mexicans living in Mexico's urban areas in five of six biomarkers of metabolic syndrome (MetS) and in the overall MetS score. Mexican migrants living in the United States experience similar patterns to Mexicans living in Mexico in glucose and obesity biomarkers. These results are inconsistent with previous findings, suggesting that Mexican migrants in the United States experience significantly attenuated health gradients relative to the non-Hispanic white U.S. Our empirical evidence also contradicts the idea that SES-health gradients in Mexico are shallower than those in the United States and could be invoked to explain shallower gradients among Mexicans living in the United States.

    Full Text Available Abstract This study intends to give recommendations to the management of Paraty fishery in Brazil through an interplay of local and scientific knowledge. In particular, the objectives are the following: 1 to describe the Paraty fishery; 2 to compare the fishermen’s local ecological knowledge with recorded fish landings and previous studies in Paraty; 3 to combine the data on local fishing and on local/Caiçara livelihoods with the SES (social-ecological systems Model. The methods include a systematic survey of fishing in Tarituba and Praia Grande, which are located in the northern end and the central part of the Paraty municipality, respectively. For four days each month, systematic data on catches at landing points were collected, as well as macroscopic gonad analysis data for the fishes Centropomus parallelus and C. undecimalis (snook, robalo, Epinephelus marginatus (grouper, garoupa, Scomberomorus cavalla (King mackerel, cavala, and Lutjanus synagris (Lane snapper, vermelho. Spring and summer are important seasons during which some species reproduce, and the integration of fishing periods for some target species could assist in fishing management through the use of closed seasons. Fishermen could obtain complementary earnings from tourism and from the “defeso system” (closed season including a salary payment to conserve fishing stocks. The SES model facilitates an understanding of the historical context of fishing, its economic importance for local livelihoods, the constraints from conservation measures that affect fishermen, and the management processes that already exist, such as the defeso. If used to integrate fishing with complementary activities (tourism, such a system could improve the responsibility of fishermen regarding the conservation of fish stocks.

    This study investigated the contribution of child characteristics and parenting environment to the relationship between family SES/demographic characteristics and maternal language to infants.1157 children were drawn from a representative sample of 1292 infants born to mothers in rural Appalachian counties and rural counties in southern minority U.S. communities. Mothers and their 6-8 month old babies were videotaped at home while talking about a wordless picture book. Mothers' language output and complexity were analyzed. Child temperament, age, and parenting environment (knowledge of child development and observed mother-child engagement) were predictors of maternal language. Furthermore, their inclusion reduced the magnitude of the association between demographic characteristics and maternal language. Tests of mediation suggested that the parenting environment partially mediates the relationship between SES/demographic characteristics and maternal language. Findings are discussed with respect to identifying proximal processes that explain how SES may exert its influence on the language of young children.

    Full Text Available The paper contributes to the social-ecological systems literature byadapting and using Elinor Ostrom’s Social-Ecological System (SES frameworkin the context of a coastal ecosystem. We modified the SES framework in thecase of the Ciénaga Grande de Santa Marta (CGSM, an estuarine lagoon inthe Caribbean coast of Colombia. The ecological importance of CGSM and itsspecies is undeniable. This paper aims to understand why collective action fora sustainable use of CGSM’s fishery resources has not taken place. In order torespond to that question, we created new variables within the social, economic,and political settings of the SES framework. The results show that the fishers’ fearof the indiscriminate and strong violence that illegal armed groups have inflictedon them since the 1960s and the economic development in the ColombianCaribbean region help explain the lack of collective action.

    Fernanda Aparecida Silva

    Full Text Available RESUMO Diante da importância da taxa de câmbio no comércio externo, considerando que suas flutuações podem modificar a escala de preços entre os países, a presente pesquisa buscou identificar o impacto da volatilidade da taxa de câmbio real bilateral sobre o fluxo de comércio entre os países da América do Sul. Para tal, foi estimado um modelo gravitacional utilizando uma amostra de nove países, entre 1998 e 2012. O método utilizado na estimação foi o modelo Poisson-Pseudo Maximum Likehood (PPML. Os resultados mostraram que a instabilidade cambial é prejudicial à relação de comércio entre países da América do Sul, já que maior incerteza cambial leva os agentes econômicos, a longo prazo, a reduzir suas atividades no comércio internacional, dada maior exposição ao risco. Outro resultado importante foi a constatação de que os países membros do Mercosul, de fato, têm o comércio favorecido diante das vantagens oferecidas pelo bloco, como a redução de tarifas comerciais. Quanto à variável utilizada para captar o efeito da crise do subprime em 2008, verificou-se aumento no fluxo comercializado pelos países sul-americanos nesse período.

  15. Guiding Young Children's Digital Media Use: SES-Differences in Mediation Concerns and Competence.

    Nikken, Peter; Opree, Suzanna J

    2018-01-01

    Previous research about parents' mediation of their young children's (digital) media use has predominantly focused on the different types, determinants, and effectiveness of parental mediation strategies. Although research on parents' perceived mediation concerns and competences is scarce, it is known that, compared to mothers and high-educated parents, fathers and low-educated parents experience greater insecurity (i.e., higher concern and lower competence) when applying media mediation. Based on Bourdieu's theory of social capital it may be expected that-in addition to educational level-marital status and family income predict parents' perceived mediation concerns and competences: Family demographics may predict parents' media proficiency and adoption of new media technologies and these media ecological factors may, in turn, affect perceived concerns and competences. To test this assumption, survey data were collected among 1029 parents of children between the ages of 1 to 9 years. We found that parents' basic media proficiency was lower in low income, low educated, and single-parent families, whereas parents' advanced media proficiency was only lower in low educated and single-parent families. As expected, parents' ease of active co-use was positively associated with parents' basic proficiency, ease of restrictive mediation by basic and advanced proficiency, and ease of imposing technical restrictions by advanced media proficiency. Parents' perceived mediation concerns were, however, unrelated to parents' media proficiency. Also, as expected, low educated parents were less inclined to adopt new media technologies. Adoption of new media was negatively related to perceived mediation concerns, yet did not predict parents' perceived competence.

    Full Text Available Diferentes estratégias de proteção social têm sido utilizadas no mundo visando combater a fome e promover a mobilidade social. Dentre elas, os programas de transferência condicionada de renda têm se destacado pelo desenho contratual e pela estrutura de governança que tem a promoção do comportamento positivo do indivíduo, e não a assistência, como elemento central. Portanto, famílias que participam desses programas recebem, em geral, determinada quantia financeira destinada a satisfazer as necessidades básicas e contribuir para o atendimento das condições positivas impostas à sua manutenção no programa. Conhecer as condicionalidades e perceber sob qual contexto de investigação essas práticas têm sido abordadas no meio acadêmico torna-se fator de relevância científica e social. Nessa direção, este trabalho teve como propósito discutir os diferentes desenhos dessa política em diversos países. Para tanto, 50 trabalhos científicos, distribuídos por 28 países, foram analisados, visando contextualizar metodologias e resultados alcançados. Para realizar tal análise, foi procedido um estudo exploratório, a partir da técnica de metaestudo, utilizando como referência a base de dados do Banco Mundial, sítios eletrônicos e artigos sobre o assunto, publicados entre 2003 e 2011, com a finalidade perceber sob qual ótica têm sido estudados os principais programas de transferência de renda do mundo. Dentre os principais resultados alcançados, merece destaque o fato de, indiferentemente do país ou programa de transferência considerado, a manutenção das crianças na escola e o cuidado com a saúde infantil são condições centrais de inclusão e manutenção da família no sistema de transferência.

    Full Text Available La globalización de los mercados lleva a un cambio radical de las formas del mercado, de las estructuras económicas Ínter e intrasectoriales, del tamaño de las empresas, así como de las estructuras de propiedad en el campo empresarial. Igualmente, se generan diferentes exigencias para las empresas y los productos a medida que la competencia internacional se intensifica. La globalización de los mercados también implica forzar una distribución internacional del empleo. A los países en desarrollo se les abren más posibilidades de crecimiento. ¿Son estos efectos positivos o negativos para el estado ambiental de los países en desarrollo? Los cambios originados por la globalización de los mercados podrían repercutir de manera positiva en el estado del medio ambiente en los paises en desarrollo. Sin embargo, un requisito muy importante para que ese sea el resultado, es que no solamente los países desarrollados sino también los países en desarrollo pongan en práctica una política ambiental razonable.

    David eTerman

    2013-08-01

    Full Text Available The egcSEs comprise five genetically linked staphylococcal enterotoxins, SEG, SEI, SElM, SElN and SElO and two pseudotoxins which constitute an operon present in up to 80% of Staphylococcus aureus isolates. A preparation containing theses proteins was recently used to treat advanced lung cancer with pleural effusion. We investigated the hypothesis that egcSEs induce nitrous oxide (NO and associated cytokine production and that these agents may be involved in tumoricidal effects against a broad panel of clinically relevant human tumor cells. Preliminary studies showed that egcSEs and SEA activated T cells (range: 11-25% in a concentration dependent manner. Peripheral blood mononuclear cells (PBMCs stimulated with equimolar quantities of egcSEs expressed NO synthase and generated robust levels of nitrite (range: 200-250 µM, a breakdown product of NO; this reaction was inhibited by NG-monomethyl-L-arginine (L-NMMA (0.3 mM, an NO synthase antagonist. Cell free supernatants (CSFs of all egcSE-stimulated PBMCs were also equally effective in inducing concentration dependent tumor cell apoptosis in a broad panel of human tumor cells. The latter effect was due in part to the generation of NO and TNF-α since it was significantly abolished by L-NMMA, anti-TNF-α antibodies respectively and a combination thereof. A hierarchy of tumor cell sensitivity to these CFSs was as follows: lung carcinoma>osteogenic sarcoma>melanoma>breast carcinoma>neuroblastoma. Notably, SEG induced robust activation of NO/TNFα-dependent tumor cell apoptosis comparable to the other egcSEs and SEA despite TNF-α and IFN-γ levels that were 2 and 8 fold lower respectively than the other egcSEs and SEA. Thus, egcSEs produced by S. aureus induce NO synthase and the increased NO formation together with TNF-α appear to contribute to egcSE-mediated apoptosis against a broad panel of human tumor cells.

  3. What factors help or hinder the achievement of low SES students? An international comparison using TIMSS 2011 8th grade science data

    Bruner, Justin L.

    Focusing on science from a cross-country perspective, this study explores the relationship between 8th grade science achievement and student, teacher, and school characteristics. More specifically, this study will pay special attention to low socio-economic status (SES) students and seek to understand why some disadvantaged students are able to have higher than expected achievement in science given their SES while other disadvantaged students are not able to achieve beyond what would be expected given their background. This study will explore the multi-level relationship between the characteristics of students, their teachers, their schools, and student achievement in science. While looking at students in classrooms and in schools, this work will create as precise as possible a measure of student SES by drawing on recommendations of an expert panel commissioned by the National Association of Educational Progress (NAEP) study. The study uses the most recent cycle (2011) of the Trends in International Math and Science Study (TIMSS), to strategically select a six-country sample from the 45 participating countries. This six-country sample was selected by using the country level achievement and the standard deviation of that achievement. This will create a sample that has a range of equality in achievement and strength in achievement. This allows for making comparisons both across and within countries to better understand variations in the factors of student performance, especially for disadvantaged students. This paper builds on the existing research around socio-economic status (SES) and achievement by exploring in more detail the conditions in schools and classrooms around the world that might magnify or reduce the effect of SES on student achievement. The analysis looks at these questions: "What conditions help low SES students achieve higher than what would be expected given their SES?" and "What conditions hinder low SES students to achieve at or below what would

Materiales y métodos: estudio descriptivo realizado a partir de una revisión de la literatura internacional y nacional en bases de datos y páginas web. Resultados: se encontró un país con índice de COP elevado; un país con índice de COP moderado; 10 países con índice de COP bajo; y 10 países con índice de COP muy bajo. Los países de desarrollo alto y los países de desarrollo bajo se comportan de manera similar en tanto reportan índices de COP inferiores al promedio mundial sugerido por la OMS (2.4. Discusión y conclusiones: se concluye que los valores de COP están asociados fuertemente a factores macroeconómicos, como las políticas y servicios de cuidado de la salud disponibles para la población, más que a la clasificación de desarrollo del Banco Mundial. Los determinantes sociales están directamente relacionados con las políticas estructurales que afectan el bienestar social, la salud y la calidad de vida de la población.

    Full Text Available Tels qu’ils existent actuellement, les procédés institutionnels de valorisation des thèses soutenues dans les universités et grands établissements français reposent sur deux circuits concomitants. En premier lieu les thèses soutenues sont déposées sous forme papier dans la bibliothèque de leur université de soutenance, où elles peuvent être consultées sur place, et prêtées par le biais du réseau de prêt entre bibliothèques. En second lieu, un exemplaire papier est transmis aux ateliers nationaux de reproduction des thèses chargés du microfichage des textes et de la diffusion systématique de ces microfiches auprès de toutes les bibliothèques universitaires. Ces deux formes de diffusion non commerciale présentent en regard des exigences des chercheurs trois inconvénients majeurs: la diffusion des thèses est géographiquement restreinte, puisque limitée aux bibliothèques universitaires; le support microfiche est jugé peu convivial; le prêt entre établissements est parfois trop lent ou onéreux, ce qui peut décourager les utilisateurs qui désirent consulter sur papier les thèses non conservées dans leur bibliothèque universitaire.

Se identificaron algunos factores de riesgo psicosocial intralaboral que propician el desarrollo y prevalencia del síndrome de burnout en estos profesionales de algunos países de América Latina como Colombia, Venezuela, Argentina y México. Se concluyó que ciertos aspectos propios de la organización del trabajo y de su realización tales como: multiplicidad de tareas, sobrecarga laboral, espacios inadecuados, falta de tiempo y de remuneración que compense los esfuerzos, son algunas de las principales fuentes de riesgos psicosociales que coadyuvan al posterior desarrollo y prevalencia del síndrome en esta población.

A través de un análisis de frontera estocástica se estima la eficiencia para probar si la aglomeración contribuye a acercar más a su frontera de productividad eficiente. Se emplea una función de producción translogarítmica, porque permite cambios tecnológicos y variaciones en las proporciones de insumos y productos de la elasticidad de escala. Los resultados muestran que en el sector manufacturero no se generaron ni mejoramientos en la eficiencia técnica ni cambios tecnológicos durante los catorce años. La evidencia sugiere que las variables ambientales determinadas por la formación bruta de capital fijo total o solo en maquinaria y equipo influyen en el comportamiento del sector.

    Shopping at low-cost supermarkets has been associated with higher obesity rates. This study examined whether attitudes toward healthy eating are independently associated with diet quality among shoppers at low-cost, medium-cost, and high-cost supermarkets. Data on socioeconomic status (SES), attitudes toward healthy eating, and supermarket choice were collected using a telephone survey of a representative sample of adult residents of King County, WA. Dietary intake data were based on a food frequency questionnaire. Thirteen supermarket chains were stratified into three categories: low, medium, and high cost, based on a market basket of 100 commonly eaten foods. Diet-quality measures were energy density, mean adequacy ratio, and total servings of fruits and vegetables. The analytical sample consisted of 963 adults. Multivariable regressions with robust standard error examined relations between diet quality, supermarket type, attitudes, and SES. Shopping at higher-cost supermarkets was associated with higher-quality diets. These associations persisted after adjusting for SES, but were eliminated after taking attitudinal measures into account. Supermarket shoppers with positive attitudes toward healthy eating had equally higher-quality diets, even if they shopped at low-, medium-, or high-cost supermarkets, independent of SES and other covariates. These findings imply that shopping at low-cost supermarkets does not prevent consumers from having high-quality diets, as long as they attach importance to good nutrition. Promoting nutrition-education strategies among supermarkets, particularly those catering to low-income groups, can help to improve diet quality. PMID:23916974

    2016-01-01

    Support for authoritarian approaches to parenting, including corporal punishment, is known to be elevated among individuals with low current levels of socioeconomic attainment. The objectives of this study are: (1) to determine whether authoritarian parenting dispositions are related to disadvantages in one's social background, in addition to one's present socioeconomic standing; and (2) to distinguish, in this regard, between support for spanking and other authoritarian parenting dispositions. Ordered logit models, applied to General Social Survey data concerning a nationally representative sample of US adults, are used to examine relationships of authoritarian parenting dispositions to the socioeconomic positions that respondents currently occupy and in which they were raised. It is found that support for spanking (N=10,725) and valuing of obedience (N=10,043) are inversely related to the socioeconomic status (SES) of one's family of origin, and that these associations are robust to controls for one's current SES. A disadvantaged family background is found to increase support for spanking most among those with high current SES. Strong associations (robust to controls for SES indicators) are additionally found between African-American racial identity and support for authoritarian parenting. Prior research indicates that authoritarian parenting practices such as spanking may be harmful to children. Thus, if the parenting attitudes analyzed here translate into parenting practices, then this study's findings may point to a mechanism for the intergenerational transmission of disadvantages.

    Full Text Available Charles Bovary est probablement le personnage qui a été le plus transformé par les cinéastes qui ont adapté le roman de Flaubert. Si les premiers adaptateurs l’ont traité en victime, peu à peu, le cinéma a commencé à souligner la dimension néfaste sous-jacente du personnage et à lui faire porter une large part de responsabilité dans la descente aux enfers d’Emma. Depuis Pierre Renoir, touchant et authentique, jusqu’à Gregg Edelman, le mari de Little children qui fantasme sur les photos d’une pin-up virtuelle, en passant par les images plus ou moins pathétiques ou ridicules de Van Heflin, Aribert Wäscher, Alberto Bello, Jean-François Balmer, Farooq Shaikh ou Luis-Miguel Cintra, Charles, plus que tout autre personnage du roman, a subi une incroyable métamorphose en s’ancrant dans la civilisation de chacun des pays et de chacune des décennies successives qui l’ont porté à l’écran.From the 1930s to the present, Charles Bovary is probably the most altered character in the adaptations of Flaubert’s novel. The first directors made a victim of him, but gradually, the cinema began to emphasize his deleterious dimension and attributed to him a large part of the responsibility for Emma’s grief. From Pierre Renoir, touching and authentic, to Gregg Edelman, who fantasizes on a pornographic website in Todd Field’s Little Children, the more or less pathetic or ridiculous portrayals given by Van Heflin, Aribert Wäscher,Alberto Bello, Jean-François Balmer, Farooq Shaikh or Luis-Miguel Cintra, show that more than any other character in the novel, Charles has been submitted to a serious metamorphosis by being interpreted on screen according to each country’s civilization and the successive decades of filming.

    Full Text Available Abstract Background Research has shown inconsistencies in results and difficulties in conceptualization of assessment of socioeconomic status (SES among adolescents. The aim of this study was thus to test the validity of self-reported information on SES in two age-groups (11–13 and 14–16 years old in an adolescent population and to evaluate its relationship to self-reported health related quality of life (HRQOL. Different measures of SES commonly used in research in relation to HRQOL were tested in this study; parent’s occupations status, family material affluence status (FAS and perceived SES. Method A cross-sectional study, with a sample of 948 respondents (n = 467, 11–13 years old and n = 481, 14–16 years old completed questionnaires about SES and HRQOL. The adolescents’ completion rates were used, with chi2-test, to investigate differences between gender and age-group. Correlation was used for convergent validity and ANOVA for concurrent validity. Results We found a low completion rate for both fathers’ (41.7 % and mothers' (37.5 % occupation status, and a difference in completion rate between gender and age-groups. FAS had the highest completion rate (100 % compared to parent's occupations status and perceived SES. The convergent validity between the SES-indicators was weak (Spearman correlation coefficient below 0.3, suggesting that the indicators measured different dimensions of SES. Both FAS and perceived SES showed a gradient in mean HRQOL between low and high SES in relation to HRQOL, this was significant only for perceived SES (p < 0.01, both age-groups. Conclusion This study indicates the need for considering different approaches to measures of SES among adolescences and when evaluating SES in relation to HRQOL. Further research is needed to investigate sustainable ways to measure SES, delineating the relevance of tangible measures of education, occupation and income in relation to the perceived

    Full Text Available O objetivo deste ensaio é explorar o tema da desigualdade econômica a partir das distribuições de renda disponível e de patrimônio nos países desenvolvidos e, de modo mais detalhado, nos Estados Unidos. A análise explora o aumento da desigualdade enquanto resultado das transformações da sociedade capitalista ocorridas nos últimos quase 40 anos, que provocaram uma desvalorização dos salários acompanhada de uma maior financeirização da renda associada à dinâmica da riqueza, isto é, do patrimônio detido por certas parcelas das populações desses países. Ele adota uma perspectiva de análise de natureza estrutural, entendendo que o aumento da desigualdade que a crise atual poderá carregar deve ser visto como parte do processo de sua ampliação produzida pelas transformações ocorridas na sociedade capitalista desenvolvida ao longo dos últimos quase 40 anos. Nestes últimos 40 anos, o capitalismo desenvolvido conheceu um processo de sistemática reorganização econômica, social e política de suas estruturas produtivas, das instituições de representação e regulação e da dinâmica da acumulação de capital. A desigualdade deve ser entendida como transformação, que teve a financeirização como instrumento relevante para a modificação da distribuição de renda.This essay debates the theme of economic inequality from the distribution of disposable income and wealth in developed countries and especially in the United States. The analysis explores the increase in inequality as a result of the transformation of capitalist society have occurred over the past forty years, which led to a devaluation of wages accompanied by greater financialization of income linked to the dynamics of wealth, i.e. the assets held by certain portions of the populations these countries.

    Full Text Available La evidencia acumulada sobre el efecto de crisis anteriores en la salud presenta patrones muy diferenciados atribuibles al diseño de los estudios, a la naturaleza de cada crisis y a otros factores del entorno socioeconómico y político. Existe, no obstante, un consenso cada vez mayor sobre el papel mediador de las respuestas políticas de los gobiernos, que pueden magnificar, o al contrario mitigar, los efectos adversos de las crisis. Estudios recientes revelan un deterioro en algunos indicadores de salud en el contexto de la crisis actual, fundamentalmente en salud mental y enfermedades transmisibles. En algunos países europeos también se ha constatado un descenso en el consumo de tabaco y alcohol. Por otro lado, algunos gobiernos están haciendo uso del contexto de crisis para avanzar reformas tendentes a la privatización de servicios y prestaciones sanitarias, restringiendo con ello el derecho a la salud y a la atención sanitaria. Se está actuando sobre los tres ejes que determinan el campo de la financiación de los sistemas sanitarios: la población protegida, la contribución del usuario y la cobertura de servicios. Estas medidas están siendo adoptadas a menudo de manera arbitraria basándose en decisiones ideológicas más que en la evidencia disponible, de lo que cabría esperar consecuencias adversas en términos de protección financiera, eficiencia y equidad.

    Full Text Available En el artículo se estudia la crisis del ciclo neoliberal en los países de la Región Andina en el contexto delos cambios políticos latinoamericanos. Es una investigación documental-analítica, fundamentada en una revisión bibliográfica y en la clasificación del material para el procesamiento de los datos recolectados, la interpretación de esos datos parte de la categoría crisis del ciclo neoliberal. El neoliberalismo reduce las funciones de los Estados andinos a las áreas medulares: educación, salud y seguridad ciudadana, privatiza las empresas estatales y los servicios públicos, donde la ¿razón del mercado¿ priva la relación Sociedad-Estado, con consecuencias nefastas para la población, originando en el tiempo el surgimiento democrático de gobiernos anti-neoliberales. Se concluye que en los albores del siglo XXI el neoliberalismo entra en crisis, cuando el mercado manifiesta su incapacidad de contrarrestar los altos índices de pobreza y el deterioro de las condiciones vida de los ¿pueblos¿, los gobiernos andinos de izquierda introducen cambios en los sistemas políticos, redimensionando las políticas de ajuste macro-económico y rechazan los acuerdos bilaterales y multilaterales promotores de libre mercado en el seno del sistema institucional de integración andina.

La formation du Ge mesoporeux par gravure electrochimique a ete precedemment rapportee dans la litterature. Cependant, le verrou technologique important des procedes de fabrication existants consistait a obtenir des couches epaisses (superieure a 500 nm) du Ge mesoporeux a la morphologie parfaitement controlee. En effet, la caracterisation physico-chimique des couches minces est beaucoup plus compliquee et le nombre de leurs applications possibles est fortement limite. Nous avons developpe un modele electrochimique qui decrit les mecanismes principaux de formation des pores ce qui nous a permis de realiser des structures epaisses du Ge mesoporeux (jusqu'au 10 mum) ayant la porosite ajustable dans une large gamme de 15% a 60%. En plus, la formation des nanostructures poreuses aux morphologies variables et bien controlees est desormais devenue possible. Enfin, la maitrise de tous ces parametres a ouvert la voie extremement prometteuse vers la realisation des structures poreuses a multi-couches a base de Ge pour des nombreuses applications innovantes et multidisciplinaires grace a la flexibilite technologique actuelle atteinte. En particulier, dans le cadre de cette these, les couches du Ge mesoporeux ont ete optimisees dans le but de realiser le procede de transfert de couches minces d'une cellule solaire a triple jonctions via une couche sacrificielle en Ge poreux.

    Studies conducted in developing countries have noted associations between concurrent stunting, social-emotional problems and poor cognitive ability in young children. However, the relative contribution of these variables in Latin America is likely changing as undernutrition rates decline and prevalence of childhood obesity rises. We conducted a cross-sectional study of 106 normal-weight and 109 obese preschool children to compare the relative contribution of early nutrition, sociodemographic factors and psychosocial variables on cognitive development in normal-weight and obese preschool children in Chile. The study variables were categorized as: (1) socio-demographic (age, sex, birth order and socioeconomic) (2) early nutrition (maternal height, birth weight, birth length and height at 5 years) (3) psychosocial factors (maternal depression, social-emotional wellbeing and home space sufficiency). In order to assess determinants of cognitive development at 4-5 years we measured intelligence quotient (IQ); variability in normal children was mostly explained by socio-demographic characteristics (r(2) = 0.26), while in obese children early nutritional factors had a significant effect (r(2) = 0.12) beyond socio-demographic factors (r(2) = 0.19). Normal-weight children, who were first born, of slightly better SES and height Z score >1, had an IQ ≥ 6 points greater than their counterparts (p birth weight >4,000 g and low risk of socio-emotional problems had on average ≥5 IQ points greater than their peers (p < 0.05). We conclude that in Chile, a post-transitional country, IQ variability of normal children was mostly explained by socio-demographic characteristics; while in obese children, early nutrition also played a significant role.

    2017-10-01

    The ability to predict spectral electro-optical (EO) signatures for various targets against realistic, cluttered backgrounds is paramount for rigorous signature evaluation. Knowledge of background and target signatures, including plumes, is essential for a variety of scientific and defense-related applications including contrast analysis, camouflage development, automatic target recognition (ATR) algorithm development and scene material classification. The capability to simulate any desired mission scenario with forecast or historical weather is a tremendous asset for defense agencies, serving as a complement to (or substitute for) target and background signature measurement campaigns. In this paper, a systematic process for the physical temperature and visible-through-infrared radiance prediction of several diverse targets in a cluttered natural environment scene is presented. The ability of a virtual airborne sensor platform to detect and differentiate targets from a cluttered background, from a variety of sensor perspectives and across numerous wavelengths in differing atmospheric conditions, is considered. The process described utilizes the thermal and radiance simulation software MuSES and provides a repeatable, accurate approach for analyzing wavelength-dependent background and target (including plume) signatures in multiple band-integrated wavebands (multispectral) or hyperspectrally. The engineering workflow required to combine 3D geometric descriptions, thermal material properties, natural weather boundary conditions, all modes of heat transfer and spectral surface properties is summarized. This procedure includes geometric scene creation, material and optical property attribution, and transient physical temperature prediction. Radiance renderings, based on ray-tracing and the Sandford-Robertson BRDF model, are coupled with MODTRAN for the inclusion of atmospheric effects. This virtual hyperspectral/multispectral radiance prediction methodology has been

Em segundo lugar, aborda a matriz energética de cada um dos cinco países do ponto de vista de suas economias políticas e da questão da sustentabilidade. Em terceiro lugar, e com base na seção anterior, propõe mapear as áreas de conflito e de possível aproximação entre os BRICS, na tentativa de localizar as possibilidades e limites da sua cooperação energética. Com base nessa investigação, conclui que, diante das potencialidades para a cooperação entre os países, a organização de suas ofertas e demandas energéticas nacionais pode permitir ao agrupamento articular-se como um novo polo no cenário energético global.

    Full Text Available Benedetto presenta una aproximación a los procesos de desarrollo territorial que están cobrando impulso en los países del Mercado Común del Sur (MERCOSUR. Retoma las grandes etapas históricas por las que ha transitado el agro en los países de América Latina en general y el MERCOSUR en particular. Luego, se revisan los rasgos centrales que tienen las actuales políticas rurales de los países miembros de MERCOSUR, en especial su manejo de las marcas y denominaciones de origen. No existe una política común de desarrollo rural; las políticas agrícolas nacionales son sólo sectoriales y se orientan a promover la productividad y la competitividad comprimiendo costos, por encima de la valorización de la calidad. Sin embargo, en la última década, Se está rescatando no sólo el entorno geográfico característico del medio rural, sino también se valorizan las formas de vida, alimentos, bienes y servicios, resultado de la identidad cultural de las poblaciones. Por último, se presentan dos iniciativas de valorización de la identidad cultural rural en Argentina: los Caminos de Altamira - San Carlos, Mendoza y El Vino de la Costa - Berisso, Buenos Aires.

    Formålet med dette studie var at undersøge ”cancer awareness”, dvs. kendskabet til symptomer på kræft, risikofaktorer for kræft og 5-års overlevelsen for fire kræfttyper, i en dansk population. Derudover ses der nærmere på sammenhænge mellem socio-økonomisk position og ”cancer awareness......”. Resultaterne viser, at der er en stærk social gradient i ”cancer awareness”. Personer med et lavt uddannelsesniveau og en lav husstandsindkomst var mindre tilbøjelige til at genkende symptomer på kræft og risikofaktorer for kræft end personer med et højt uddannelsesniveau og en høj husstandsindkomst....... Resultaterne viser dog ingen klar sammenhæng mellem socio-økonomisk position og kendskabet til 5-års overlevelsen af kræft.

    Full Text Available É compreensível que devido a relevância dos relatórios contábeis e sua maior importância com a adoção das IFRS haja nas empresas uma preocupação com os fatores que causam interferência na sua qualidade, bem como, com os critérios utilizados na sua formação, consistência e avaliação. Dentre os fatores que exercem influencia na qualidade das informações contábeis está o conservadorismo, definido por Basu (1997 como um reconhecimento assimétrico das perdas em relação aos ganhos, se refletem as más notícias mais rapidamente do que as boas notícias. Considerando este contexto, o presente estudo tem o objetivo de avaliar as magnitudes das influências das IFRS nos níveis de conservadorismo contábil das práticas adotadas nos países membros do GLENIF, mais especificadamente, Argentina, Brasil, Chile, Colômbia, México e Peru no período de 2003 a 2013. Com uma amostra de 513 empresas e 5643 observações, aplicou-se por meio de dados em painel a equação original de Basu (1997 e, posteriormente, incluiu-se uma variável dummy considerando os efeitos da adoção das IFRS no conservadorismo. Os resultados indicaram que, mesmo com a adoção das IFRS notou-se no Brasil e no México a presença de práticas conservadoristas. Na Argentina constatou-se situação contrária, as IFRS amenizaram o conservadorismo nas empresas do país. Já no Chile, Colômbia e Peru os resultados não significativos foram insuficientes para indicarem a presença de conservadorismo após a adoção das IFRS.

El desarrollo de la Enseñanza Uni versi taria atendiendo a estos parámetros permiten presentar a la uni versidad británica como modelo institucional actual frente al concepto, valores y la apuesta investigadora tradicionales característicos de la uni versidad humboldtiana alemana, reacia a los cambios que exige la embestida neoconservadora de la década de los noventa.

I will then bring out the empirical implications from a number of extracts selected from his works. I will conclude by examining his “synoptic” approach, one to be followed by all sociologists.

    Full Text Available Le modèle de démocratie libérale occidentale serait-il approprié à une analyse des nouveaux régimes politiques de la Troisième Vague démocratique? Dans cet article, après une récapitulation de la littérature sur la démocratisation et la réforme économique, on fait état de quelques concepts significatifs: gouvernabilité, gouvernance et démocratie, ainsi que de leurs biais normatifs implicites. On a examiné surtout le concept de démocratie qui se fonde sur le procedural minimum de Schumpeter/Dahl. Bien que considérée trop étroite par des auteurs importants, cette définition de démocratie, qui a reçu des qualificatifs la précisant davantage, a gagné du terrain. Au lieu d’en rajouter d’autres à la liste de Dahl, on propose ici qu’on tienne compte, lors de l’étude des régimes en changement, des caractéristiques du processus de décision en tant qu’instrument analytique à même d’identifier les nouveaux systèmes politiques selon leurs propres termes. Cette approche semble plus pertinente pour l’examen du caractère plus ou moins démocratique des régimes en construction dans les périodes entre les élections, faisant ressortir la question du contrôle vertical des bureaucraties, insuffisamment traitée par la théorie démocratique. On réussit à identifier aussi différents types de démocratie qui associent de façon diverse les caractéristiques de leur processus de décision. Enfin, à partir du cas brésilien, on présente quelques considérations sur le type de régime politique que les pays émergents sont capables de construire, ou se disposent à construire, tout en leur suggérant quelques hypothèses de travail et d’analyse.

    Full Text Available Na medida em que a população mundial está envelhecendo, a demência está se constituindo em importante problema de saúde pública, particularmente nos países em desenvolvimento. Investigações epidemiológicas nestes países são escassas e apresentam dificuldades metodológicas adicionais, principalmente no que se refere à adequação sociocultural dos instrumentos utilizados para a definição de casos. Tendo em vista estas preocupações, foi fundado o "Grupo de Pesquisa em Demência 10/66", que é constituído por uma rede internacional de pesquisadores, predominantemente de países em desenvolvimento. O nome do grupo tem como referência o paradoxo de que menos de 10% dos estudos populacionais sobre demência são dirigidos aos 2/3 ou mais de casos de pessoas com demência que vivem em países em desenvolvimento. O objetivo do artigo é atualizar informações da literatura sobre as diferenças de prevalência e incidência de demência encontradas em países desenvolvidos e em desenvolvimento.As the world population is ageing, dementia becomes an important public health problem, particularly in developing countries. Epidemiological research in these settings is scarce and present additional methodological difficulties, mainly regarding the socio-cultural adequacy of instruments used to identify cases of dementia. As a result of these concerns the 10/66 Dementia Research Group was founded to fill this gap. This is an international network of investigators, mostly from developing countries, and the group's name was based on the paradox that less than 10% of the population-based studies on dementia are directed to 2/3 or more cases of people with dementia living in developing countries. The aim of the paper is to update data in the literature regarding the differences in dementia prevalence and incidence seen in developed and developing countries.

Il est l'incarnation même de l'artiste au cœur de son peuple, lui qui s'est imposé dans le champ artistique avec son talent, son franc-parler, sa musique et sa poésie. Son parcours ne peut être dissocié de ses engagements politiques. Il combat les fondamentalistes islamistes et s'oppose au pouvoir en place. Il veut la reconnaissance du berbère, sa langue maternelle et celle de ses chansons, par l’État algérien. Il porte un regard sur l’histoire en reprenant des mythes tout en révélant des vérités. Il brise également des tabous de la société mais reprend des poncifs. Ses chansons, dans lesquelles se reconnaissent des milliers de personnes, disent les contradictions d'un individu tourmenté. L'imaginaire de ses poèmes est régional et rural. En revanche, son désir tend vers la nation entière et même vers l'universel. La tragédie de sa vie est indissociable des durs contextes politiques qu'expriment ses paroles. Algerian poet, singer and songwriter Lounès Matoub became an icon after his assassination. In the hearts of his people, he is the embodiment of an artist, having established himself with his talent, his outspokenness, his music and his poetry. His career cannot be dissociated from his political commitments. He fights against the Islamic fundamentalists and rebels against the governing power. He wants Berber, his mother language and that of his songs, recognized by the Algerian government. He examines history by recycling myths while revealing truths. He breaks societal taboos but unravels clichés. His songs tell of the trials of a tormented individual, but thousands of people recognize themselves in his songs. The scope of his poems is regional and rural. However, his desire extends to the whole nation, even to the universal. The tragedy of his life is inseparable from the tough political context that his words describe.

La littérature anglo-saxonne insiste en effet beaucoup sur le rôle déterminant de l’arrivée d’artistes plus ou moins marginaux (ceux de la scène dite off dans le déclenchement de la gentrification d’un quartier. Ces artistes sont considérés non seulement comme des initiateurs de la revalorisation symbolique des quartiers qu’ils investissent, mais aussi comme des ferments d’un changement d’ambiance qui permettrait l’arrivée de gentrifieurs plus aisés. Cet article met à l’épreuve ce schéma explicatif à partir de l’étude du cas de Belleville à Paris. Il mobilise pour ce faire deux enquêtes, l’une sur le rapport à leur quartier des habitants de deux rues particulièrement gentrifiées, l’autre sur le marché immobilier. Il apparaît que les artistes sont plus des témoins ou des indicateurs de la gentrification que des déclencheurs ou des catalyseurs. Ils sont partie prenante d’un mouvement de revalorisation de la centralité et de ses ressources (notamment culturelle qui les dépassent. Ce mouvement les dépasse d’autant plus que l’éthique « artiste » s’est largement diffusée dans toutes les couches de la société.This article aims at reassessing the role of artists, and more specifically the role of squatters in the gentrification process. The Anglo-American literature argues that artists influx, especially the underground ones (that we call off, is the key element to trigger the gentrification process in a neighbourhood.

    Full Text Available This paper reviews the current knowledge of leishmaniasis epidemiology in Venezuela, Colombia, Ecuador, Peru, and Bolivia. In all 5 countries leishmaniasis is endemic in both the Andean highlands and the Amazon basin. The sandfly vectors belong to subgenera Helcocyrtomyia, Nyssomiya, Lutzomyia, and Psychodopygus, and the Verrucarum group. Most human infections are caused by Leishmania in the Viannia subgenus. Human Leishmania infections cause cutaneous lesions, with a minority of L. (Viannia infections leading to mucocutaneous leishmaniasis. Visceral leishmaniasis and diffuse cutaneous leishmaniasis are both rare. In each country a significant proportion of Leishmania transmission is in or around houses, often close to coffee or cacao plantations. Reservoir hosts for domestic transmission cycles are uncertain. The paper first addresses the burden of disease caused by leishmaniasis, focusing on both incidence rates and on the variability in symptoms. Such information should provide a rational basis for prioritizing control resources, and for selecting therapy regimes. Secondly, we describe the variation in transmission ecology, outlining those variables which might affect the prevention strategies. Finally, we look at the current control strategies and review the recent studies on control.Este trabalho revisa o conhecimento atual sobre a epidemiologia da leishmaniose na Venezuela, Colômbia, Equador, Peru e Bolívia, países nos quais a doença é endêmica, tanto nos Andes quanto na Amazônia.

    Perceptual-motor skills contribute to a variety of basic learning skills associated with normal academic success. This study aimed to determine the relationship between academic performance and perceptual-motor skills in first grade South African learners and whether low SES (socio-economic status) school type plays a role in such a relationship. This cross-sectional study of the baseline measurements of the NW-CHILD longitudinal study included a stratified random sample of first grade learners (n = 812; 418 boys and 394 boys), with a mean age of 6.78 years ± 0.49 living in the North West Province (NW) of South Africa. The Beery-Buktenica Developmental Test of Visual-Motor Integration-4 (VMI) was used to assess visual-motor integration, visual perception and hand control while the Bruininks Oseretsky Test of Motor Proficiency, short form (BOT2-SF) assessed overall motor proficiency. Academic performance in math, reading and writing was assessed with the Mastery of Basic Learning Areas Questionnaire. Linear mixed models analysis was performed with spss to determine possible differences between the different VMI and BOT2-SF standard scores in different math, reading and writing mastery categories ranging from no mastery to outstanding mastery. A multinomial multilevel logistic regression analysis was performed to assess the relationship between a clustered score of academic performance and the different determinants. A strong relationship was established between academic performance and VMI, visual perception, hand control and motor proficiency with a significant relationship between a clustered academic performance score, visual-motor integration and visual perception. A negative association was established between low SES school types on academic performance, with a common perceptual motor foundation shared by all basic learning areas. Visual-motor integration, visual perception, hand control and motor proficiency are closely related to basic academic skills

    Full Text Available Children from low-SES families are known to show delays in aspects of language development which underpin reading acquisition such as vocabulary and listening comprehension. Research on the development of morphological skills in this group is scarce, and no studies exist in French. The present study investigated the involvement of morphological knowledge in the very early stages of reading acquisition (decoding, before reading comprehension can be reliably assessed. We assessed listening comprehension, receptive vocabulary, phoneme awareness, morphological awareness as well as decoding, word reading and non-verbal IQ in 703 French first-graders from low-SES families after 3 months of formal schooling (November. Awareness of derivational morphology was assessed using three oral tasks: Relationship Judgment (e.g., do these words belong to the same family or not? heat-heater … ham-hammer; Lexical Sentence Completion [e.g., Someone who runs is a …? (runner]; and Non-lexical Sentence Completion [e.g., Someone who lums is a…? (lummer]. The tasks differ on implicit/explicit demands and also tap different kinds of morphological knowledge. The Judgement task measures the phonological and semantic properties of the morphological relationship and the Sentence Completion tasks measure knowledge of morphological production rules. Data were processed using a graphical modeling approach which offers key information about how skills known to be involved in learning to read are organized in memory. This modeling approach was therefore useful in revealing a potential network which expresses the conditional dependence structure between skills, after which recursive structural equation modeling was applied to test specific hypotheses. Six main conclusions can be drawn from these analyses about low SES reading acquisition: (1 listening comprehension is at the heart of the reading acquisition process; (2 word reading depends directly on phonemic awareness and

    Full Text Available Abstract Background Since 2009, when the revised Pharmaceutical Affairs Act was enacted in Japan, self-medication practices have increased. Because the concept of self-medication was recently introduced in Japan, few studies exist on this topic. Therefore, it is necessary to explore how self-medication is practiced. This study examined Japanese consumers’ self-medication practices and attitudes toward over-the-counter (OTC medicines based on their sex, age, and socioeconomic status (SES. Methods The participants were 403 adults (Mage = 41.1 years, SD = 16.22. A quota sampling method was employed based on age group, and participants completed an online questionnaire. Results Participants in the 20–29 age group reported medical costs as an obstacle in seeing a doctor; in contrast, transportation was a mitigating factor for elderly people. Regarding SES, people at lower SES levels chose to rest instead of seeing a doctor or purchasing over-the-counter (OTC medicines when sick. They also placed more value on national brand OTC medicines than private brands (likely due to advertisements. This finding suggests individuals with a low SES do not select OTC medicines based on their effects or ingredients. Regarding attitudes toward OTC medicines, Japanese participants seemed to be unaware of the potential for abuse and side effects associated with OTC medicines. Finally, in relation to caregivers’ self-medication practices for their children, the majority of participants reported taking their children to the hospital since children tend to receive free medical care. Furthermore, caregivers with a high educational background are more confident in being able to help manage their children’s health. Conclusions Our results suggest that health and medical discrepancies among Japanese consumers pose new social problems. In Japan, universal health care is available, but the cost of receiving medical care is not completely free of charge. Thus

    Full Text Available O presente artigo propõe analisar a questão energética entre os BRICS e o potencial de rearticulação da ordem energética global que dela emerge. Para tal, realiza três movimentos. Em primeiro lugar, investiga o crescente impacto agregado dos países BRICS no cenário energético global, com vistas a analisar seu avanço em uma temática até então reduto dos países desenvolvidos. Em segundo lugar, aborda a matriz energética de cada um dos cinco países do ponto de vista de suas economias políticas e da questão da sustentabilidade. Em terceiro lugar, e com base na seção anterior, propõe mapear as áreas de conflito e de possível aproximação entre os BRICS, na tentativa de localizar as possibilidades e limites da sua cooperação energética. Com base nessa investigação, conclui que, diante das potencialidades para a cooperação entre os países, a organização de suas ofertas e demandas energéticas nacionais pode permitir ao agrupamento articular-se como um novo polo no cenário energético global.The article analyzes energy-related issues among the BRICS countries and the potential refashioning of the world energy order that might spring from them. It begins by investigating the growing impact of the BRICS countries within the international order, with the intention of tracking their progress in an ambit so far restricted to developed countries and their oil suppliers. The text subsequently analyzes the energy matrix of each of the five BRICS countries from the points of view of political economy and sustainability. Finally, based on the previous sections, the final section of the article maps the tensions and complementarities between the BRICS and outlines the possibilities and limits of their cooperation on energy issues. The analysis concludes that given the potential for energy-related cooperation between these countries, a clear definition of their national energy supply and demand may allow the grouping to position

    Full Text Available A discussion of health policy in developing countries is presented. It argues that developing countries must adopt a progressive approach to health policy which rejects the two-tiered system of public and private health care. However, it also points out that ideology is not sufficient to maintain support. A progressive health system must utilize administrative and social and behavioral sciences to achieve effectiveness and efficiency in health care delivery. It cannot ignore these goals any more than a private health care system can.É discutida a política de saúde em países em desenvolvimento. Defende-se a proposta de que esses países devem adotar uma abordagem progressista quanto a sua política de saúde, rejeitando o sistema que se apoia em dois pilares - o da saúde pública e privada. Salienta-se que a ideologia não pode ser seu único sustentáculo. Um sistema de saúde progressista deve utilizar as ciências administrativas, sociais e comportamentais na formulação e implementação do conjunto de seus programas e propostas, para que possa servir à população de modo eficaz. O sistema de saúde pública não pode se eximir em relação a meta da eficácia.

    Full Text Available O presente estudo tem o objetivo de verificar se investimentos simultâneos em vários mercados internacionais de ações são mais atrativos do que aqueles realizados somente em um único mercado nacional, ou seja, se os primeiros apresentam uma relação risco-retorno superior. Pode-se admitir que se houver uma total integração entre os países analisados, tem-se pouca vantagem na diversificação internacional, mas se os mesmos forem menos integrados, a diversificação traria vantagens em termos de risco e retorno. A base empírica do trabalho está fundamentada na teoria de carteiras de Markowitz, no CAPM e nos índices de medição do desempenho de carteiras de Sharpe, Treynor e Jensen. A análise foi feita para o período de fevereiro de 1993 a janeiro de 2003, com base nas ações mais negociadas nas bolsas dos principais países da América Latina. Os resultados mostraram que a diversificação de carteiras em mercados internacionais é mais indicada.

    Full Text Available Se propone un modelo teórico para explicar la heterogeneidad observada en la adopción de leyes antidumping por pequeños países en vía de desarrollo en un contexto de reducción arancelaria multilateral. El análisis se basa en un juego de tres etapas de determinación de política comercial con competencia imperfecta en productos diferenciados, donde la posible presión para la protección se refleja en la función objetivo del gobierno y donde los aranceles se pueden consolidar como resultado de acuerdos comerciales multilaterales. Este marco implica que la aplicación de este dispositivo de protección administrativa es la mejor respuesta del gobierno cuando los aranceles consolidados multilaterales alcanzan un umbral los suficientemente bajo. La heterogeneidad en la decisión de adopción se explica por el tamaño relativo del mercado nacional, el grado de diferenciación de los productos y los motivos de economía política. Las relativamente grandes economías, los mercados nacionales altamente competitivos y los países con una alta presión interna para la protección promulgan leyes antidumping mucho más rápido.

Para ello se utiliza el método generalizado de momentos (GMM, con un modelo dinámico de datos de panel para 47 países, entre 1990 y 2014. Los resultados revelan que existe un impacto positivo del desarrollo del mercado de seguros sobre el crecimiento económico. Además, la relación entre el desarrollo del mercado asegurador y el crecimiento económico se ve aminorada en un entorno institucional relativamente más sólido. Por otra parte, los resultados sugieren que el impacto positivo del desarrollo del mercado de seguros en el crecimiento económico se mitiga en los países de ingresos altos.

    Full Text Available Este trabajo pretende analizar las desigualdades existentes entre los inmigrantes provenientes de países pobres y la población autóctona en relación al riesgo de padecer privación material. Asumiendo que, aunque buena parte de este riesgo es inherente a la clase social, hay factores asociados al perfil migratorio que comportan un aumento de dicho riesgo. El trabajo se ha realizado implementando una combinación de análisis factoriales y de clasificación para identificar perfiles de privación material y un análisis logístico multinomial para explorar qué factores sociodemográficos están más asociados a cada tipo de estos. Los resultados confirman que la clase social es un factor muy poderoso para explicar la privación material de los inmigrantes procedentes de países pobres, pero no es el único.

    Full Text Available En el decenio de los 2000 la desigualdad del ingreso en la América Latina se redujo. Este artículo aplica una variante de la metodología de descomposición no paramétrica propuesta por Barros et al (2006, 2007 para evaluar la importancia de las fuentes de ingreso de los hogares, en particular la aportación de las transferencias públicas, en los cambios en la desigualdad de ingresos en los años 2000 en los países del Cono Sur: Argentina, Brasil, Chile y Uruguay. Los resultados sugieren que los ingresos no laborales tuvieron una contribución significativa en los cambios en la desigualdad y que este efecto fue explicado principalmente por la consecuencia igualadora que tuvieron las fuentes públicas en los cuatro países analizados. La dinámica de los cambios en esta fuente de ingreso y su efecto en la desigualdad estuvo fuertemente asociada con la instrumentación o expansión de programas de transferencia no contributivos en el pasado decenio.

Los resultados indican que las familias consideran las peleas, los insultos y las malas palabras en clase como los aspectos más frecuentes en sus centros, y coinciden en señalar el uso o presencia de objetos de agresión y el consumo o presencia de drogas como conflictos menos frecuentes en los centros escolares. En cuanto a la repercusión personal, son los problemas relacionados con el profesorado, las peleas y las dificultades de convivencia intercultural los aspectos que más preocupan. Por países, es Hungría quien presenta tasas más bajas en este tipo de problemas, estando en el lado opuesto Austria y la República Checa y situándose España en un puesto intermedio; del mismo modo, son las familias húngaras quienes se muestran menos afectadas personalmente, destacando únicamente la preocupación de éstas por los problemas de convivencia intercultural.

MÉTODOS: Diseño cualitativo, utilizando análisis de contenido de fuentes primarias y secundarias, revisiones documentales, entrevistas, grupos focales y análisis de casos Las variables seleccionadas incluyeron: criterios de selección, acceso, financiación y regulación en los distintos países. Los MAC se clasificaron en aquellos que no modifican el curso natural de la enfermedad y aquellos que tiene eficacia demostrada, utilizando la dosis diaria definida para comparar los costos entre tratamientos clásicos y los realizados con MAC. RESULTADOS: Los países del Mercosur carecen en su gran mayoría de estrategias formales para enfrentar las demandas de MAC, y gobiernos y aseguradoras terminan por financiarlos por vía judicial. Los análisis de casos muestran que existen MAC sin eficacia comprobada que igualmente generan demanda. Las compras atomizadas, los compromisos internacionales respecto a propiedad intelectual y el bajo poder de negociación incrementan los precios de MAC exponencialmente, poniendo en riesgo la economía de los sistemas sanitarios. CONCLUSIONES: Los MAC deben ser regulados y seleccionados racionalmente permitiendo que solo aquellos que beneficien sustantivamente a la población sean aceptados. Para financiar los MAC así seleccionados se requieren estrategias comunes entre países que incluyan opciones tales como flexibilidades de acuerdos comerciales, creación de fondos nacionales de recursos o compra conjunta entre países para potenciar su poder de negociación.OBJECTIVE: Determine how the Mercosur countries access, regulate, and finance costly drugs and propose joint selection and financing strategies at the subregional level.

O ritmo de maior crescimento populacional observa-se nos países subdesenvolvidos sendo que, para o ano 2.000, a região denominada de terceiro mundo é a que apresentará o maior contingente populacional pois os países subdesenvolvidos contribuirão com 79% do total da população mundial. A primeira transição demográfica iniciou-se no século 17, na Europa, com o processo de revolução industrial enquanto que, nos países subdesenvolvidos, isto ocorreu a partir do ano de 1940, porém, com uma diferença fundamental, pois a queda de mortalidade verificada não foi acompanhada por um declínio significativo da natalidade nem da modernização de suas economias. Entre os principais fatôres que afetam a mortalidade e a fertilidade analisou-se a influência do desenvolvimento econômico e social e dos avanços no campo da medicina e da saúde pública. Está sob uma política antinatalista oficial 66% da população dos países subdesenvolvidos e os contraceptivos mais utilizados têm sido, em ordem decrescente, o dispositivo intrauterino, esterilização e pílulas.

    Shopping at low-cost supermarkets has been associated with higher obesity rates. This study examined whether attitudes toward healthy eating are independently associated with diet quality among shoppers at low-cost, medium-cost, and high-cost supermarkets. Data on socioeconomic status (SES), attitudes toward healthy eating, and supermarket choice were collected using a telephone survey of a representative sample of adult residents of King County, WA. Dietary intake data were based on a food frequency questionnaire. Thirteen supermarket chains were stratified into three categories: low, medium, and high cost, based on a market basket of 100 commonly eaten foods. Diet-quality measures were energy density, mean adequacy ratio, and total servings of fruits and vegetables. The analytical sample consisted of 963 adults. Multivariable regressions with robust standard error examined relations between diet quality, supermarket type, attitudes, and SES. Shopping at higher-cost supermarkets was associated with higher-quality diets. These associations persisted after adjusting for SES, but were eliminated after taking attitudinal measures into account. Supermarket shoppers with positive attitudes toward healthy eating had equally higher-quality diets, even if they shopped at low-, medium-, or high-cost supermarkets, independent of SES and other covariates. These findings imply that shopping at low-cost supermarkets does not prevent consumers from having high-quality diets, as long as they attach importance to good nutrition. Promoting nutrition-education strategies among supermarkets, particularly those catering to low-income groups, can help to improve diet quality. Copyright © 2014 Academy of Nutrition and Dietetics.

  10. Pretty Easy Pervasive Positioning

    2009-01-01

    With the increasing availability of positioning based on GPS, Wi-Fi, and cellular technologies and the proliferation of mobile devices with GPS, Wi-Fi and cellular connectivity, ubiquitous positioning is becoming a reality. While offerings by companies such as Google, Skyhook, and Spotigo render...... positioning possible in outdoor settings, including urban environments with limited GPS coverage, they remain unable to offer accurate indoor positioning. We will demonstrate a software infrastructure that makes it easy for anybody to build support for accurate Wi-Fi based positioning in buildings. All...... that is needed is a building with Wi-Fi coverage, access to the building, a floor plan of the building, and a Wi-Fi enabled device. Specifically, we will explain the software infrastructure and the steps that must be completed to obtain support for positioning. And we will demonstrate the positioning obtained...

  11. Positive criminology in practice.

    Science.gov (United States)

    Ronel, Natti; Segev, Dana

    2014-11-01

    The discourse regarding offender rehabilitation has been criticized by various scholars who have claimed that reducing negative causes and managing risk will not automatically prompt positive human development and elements that are associated with desistance. Positive criminology is an innovative concept that challenges the common preoccupation with negative elements, by placing emphasis on human encounters and forces of inclusion that are experienced positively by target individuals and that can promote crime desistance. However, as the concept is relatively new, there are still no guiding principles for the practice of positive criminology that could direct research and the criminal justice system. This article attempts to fill that gap by providing principles that could be practiced by criminal justice personnel and examples of different interventions that reflect positive criminology. The article also provides ideological explanations for adopting the concept of positive criminology in practice. © The Author(s) 2013.

  12. Parcours croisés de Dominique Cabrera, cinéaste, et de ses proches collaborateurs. Intersecting careers: Dominique Cabrera, film director, and her close collaborators.

    Full Text Available Le métier de réalisateur de cinéma a été peu étudié en sciences humaines et sociales. Les études cinématographiques et la presse spécialisée s’intéressent beaucoup moins aux parcours des collaborateurs de l’équipe technique qu’aux comédiens et aux projets des auteurs que l’on pourrait croire retranchés dans leur intériorité créatrice. Pour échapper à ce travers biographique, le sociologue peut rendre compte de l’itinéraire d’un réalisateur en examinant ses liens avec ses collaborateurs. On prend ici l’exemple des liens de travail récurrents qui unissent Dominique Cabrera, réalisatrice de cinéma, à ses proches collaborateurs, en montrant de quelle manière des liens de travail peuvent s’approfondir en dépit d’un contexte sectoriel où l’organisation par projet de l’activité cinématographique favorise a priori la fugacité des relations de travail. On postule ainsi que le contexte pertinent pour éclairer les contours de cet itinéraire de carrière est le réseau des relations socioprofessionnelles au sein duquel naissent les projets de films et qui contribuent à ancrer ce parcours dans le paysage professionnel des pratiques cinématographiques.In France, social sciences and humanities have paid little attention to the profession of film director. Film studies and the press are much less interested in the professional careers of technical teams in comparison with the lives of actors and authors of projects who seem to be cut into their inner creativity. To escape the biographical pitfall, sociologists may account for a director’s itinerary by analyzing his/her ties with colleagues. Here, we examine the recurrent work relations between film director Dominique Cabrera and her close colleagues, to underline the strong relationships which paradoxically unite both the director and her staff in a project-based industry that is rather conducive to short-lived work relations. We postulate that the

    Full Text Available El manejo de residuos sólidos es un desafío para las autoridades de las ciudades de los países en desarrollo, principalmente debido al incremento en su generación, la carga impuesta sobre el presupuesto municipal como resultado de los altos costos asociados a su manejo, la falta de comprensión sobre una diversidad de factores que afectan las diferentes etapas del manejo de residuos y los vínculos necesarios para habilitar el funcionamiento de todo el sistema de manejo. Un análisis de la literatura sobre el trabajo realizado y reportado principalmente en publicaciones de 2005 a 2011, relacionadas con el manejo de residuos en los países en desarrollo, demostró que pocos artículos brindan información cuantitativa. El análisis se realizó en dos de las revistas científicas más importantes en gestión de residuos, Waste Management Journal y Waste Management and Research. El objetivo de esta investigación fue determinar las acciones y el comportamiento de los actores sociales que juegan un papel en el proceso de manejo de residuos y analizar factores influyentes en el sistema, en más de 30 áreas urbanas en 22 países en desarrollo de tres continentes. En este estudio se utilizó una combinación de métodos para evaluar a los actores sociales involucrados y los factores que influyen en el manejo de residuos en las ciudades. Se recogieron datos de la literatura científica, bases de datos existentes, observaciones realizadas durante visitas a áreas urbanas, entrevistas estructuradas con profesionales de relevancia, ejercicios suministrados a los participantes en talleres y un cuestionario aplicado a los actores involucrados. Se utilizaron métodos estadísticos descriptivos e inferenciales para sacar conclusiones. El resultado de la investigación es una lista completa de los actores sociales involucrados que son pertinentes en los sistemas de manejo de residuos y un juego de factores que revelan las causas más importantes del

    Full Text Available O objetivo desta pesquisa foi calcular o Índice de Ecoeficiência (IE para 51 países por meio do método Análise Envoltória de Dados (DEA. Verificou-se que o valor da ecoeficiência média diminuiu entre os anos de 1991 e 2012. Houve predominância dos países desenvolvidos e do continente europeu nos maiores índices de ecoeficiência. Os piores resultados foram alcançados por Índia e China. De modo geral, em todos os anos, o IE foi muito baixo na maioria dos países, sendo que metade destes são países em desenvolvimento e localizados, predominantemente, no continente asiático. A principal implicação dos resultados obtidos é de que são necessárias regulamentações mais rigorosas acerca do tema ambiental, principalmente para os países que apresentaram baixos valores de ecoeficiência. A presente análise sobre o Índice de Ecoeficiência busca ampliar o conhecimento sobre o assunto para propor melhores alternativas para alcançar a sustentabilidade tão necessária para as futuras gerações.

Structure: A scanning circuit is provided to scan positions of controllably mounted control bodies such as control rods. Values detected by scanning the positions are converted into character signals according to the values and converted into preranked color signals. The character signals and color signals are stored in a memory circuit by synchronous signals in synchronism with the scanning in the scanning circuit. Outputs of the memory circuit are displayed by a display unit such as a color Braun tube in accordance with the synchronous signals to provide color representations according to positions to which control bodies are driven in the same positional relation as the mounting of the control bodies.

We intend to review in this chapter its definition, clinical features, etiology and the way of exploring it. Method: narrative review. Results: Positional vertigo is the most frequent vestibular disorder, and most of the times of peripheral cause. Characteristics of nystagmus or its association with other neurological symptoms are sufficient grounds to request a magnetic resonance, which will provide additional information on very few occasions. Discussion: The study of the positional nystagmus as a procedure to rule out central pathology has lost much of its relevance. Signs that Nylén defined mixed findings peripheral and central, making complex classification. Conclusion: Regardless of how to bring the patient change position (very slow or fast, if it appears an atypical nystagmus should rule out a central origin.

    Full Text Available The positioning strategy has suffered serious changes in the last few decades, being influenced by the rapid development of competition and the growing focus on specific traits belonging to the market, to the consumer or to the product. The purpose of this paper is to present the developments of theoretical positioning strategies and the orientation from more simple, product oriented strategies, to ones more oriented towards the client and with a briefer period of time. The world is moving in a much faster pace than in the past, thanks to communication development so companies are obliged to adopt more specific strategies in order for them to be effective. This essay represents a literary review presenting a documentary research within the scientific articles and strategy and positioning books. The paper begins with the analysis of company strategies and the marketing strategies in general. The first author to group the product positioning strategies is Porter with his three generic strategies. Following the development of brands and because of the lack of competitiveness in the simple generic positioning strategies, this paper has also presented the newer positioning strategies proposed by Kotler, Treacy & Wiersema, and also more complex ones such as Bowman's Strategy Clock and Blankson and Kalafatis positioning strategy based on the type of the consumer. The fast expansion of local brands in all categories has led to mistakes in positioning strategies, categories also presented in the current essay. The results of this study show that new positioning strategies are more and more based on the consumer and market segments and on the product specification - which have also evolved in the last decades. Adaptability to fast changes in the competitive market will represent the future positioning strategies.

Data on a representative sample of U.S. adults was obtained from the Behavioral Risk Factor Surveillance System (BRFSS). Breast and colorectal cancer screening were defined in line with U.S. Preventative Services Task Force guidelines, and survey weighted statistical methods were utilized to analyze trends in cancer screening among 1,858,572 BRFSS participants. Overall, 83% of women received mammograms in the past 2 years, while 95% of adults received colorectal cancer screening in the past 10 years. Compared with the pre-recession period, the odds of colorectal screening within 5 years were slightly higher during the recession (OR: 1.05, 95% CI: 1.03-1.08) but significantly lower in the post-recession/ACA period (OR: 0.73, 95% CI: 0.72-0.75). Odds of mammography screening were lower during (OR: 0.94,95% CI: 0.91-0.96) and post-recession/ACA period (OR: 0.80, 95% CI: 0.78-0.82). Breast cancer screening rates declined in the recession and post-recession, while colorectal cancer screening rates increased during the recession and decreased post-recession. Low SES adults and those without healthcare coverage were the least likely to receive screening.

    2014-06-01

    Full Text Available En los años recientes, varios países latinoamericanos han realizado importantes reformas a sus legislaciones relacionadas con la disciplina privada del contrato de seguro. Particularmente Chile y Perú procedieron a ello, en el primer caso, sustituyendo el capítulo correspondiente al contrato de seguro en su Código de Comercio de muy antigua vigencia, y en el segundo, expidiendo una ley específica sobre el tema. También países como México y Panamá, dentro del marco de sus normas de derecho público destinadas a regular la actividad financiera y de seguros, han expedido leyes nuevas relacionadas con la vigilancia y el control de la actividad aseguradora, que necesariamente se proyectan en mayor o menor medida sobre las relaciones particulares que surgen entre asegurados y aseguradores. El conocimiento de esas nuevas legislaciones es un elemento insustituible para la reforma que tarde o temprano deberá operarse sobre la nuestra que data ya de más de cuarenta años. Temas como la reticencia o inexactitud en la declaración del estado del riesgo, la agravación del riesgo, la imperatividad de las normas regulatorias del contrato, la identificación de las partes, la regulación de la oferta y de la etapa precontractual en el contrato de seguro, y muchas otras, son objeto de análisis y comentario en este artículo.

    Full Text Available En este artículo se investigan las tendencias actuales de la migración calificada de latinoamericanos y caribeños dirigida a países de la OCDE, focalizando a Estados Unidos. A partir de un análisis bibliográfico se discuten las perspectivas teóricas sobre migración calificada y se detectan las tendencias históricas de este proceso en América Latina. Para el análisis empírico se utilizó una novedosa base de datos sobre tasas de emigración según nivel educativo. La evidencia empírica demostró que se registró un incremento del stock de migrantes con estudios superiores entre 1990 y 2000, en términos absolutos y relativos respecto a los migrantes con niveles educativos bajo y medio. Las mujeres experimentaron una tasa de emigración calificada mayor que los hombres. Los pequeños Estados, con escaso nivel de desarrollo, tienen las tasas de migración calificada más elevadas. Paradójicamente, los países con diásporas más reducidas muestran los niveles de selectividad más altos. Aproximadamente 40 por ciento de los profesionales no encuentran empleo en profesiones de ámbito científico e ingenierías encontrándose subocupados y su talento desperdiciado.

La investigación pretende responder a las preguntas señaladas mediante el estudio de los programas de noticias y magazines de las estaciones de televisión líderes del área andina, en razón de que sus contenidos se emiten en tiempo real cuando se generaría el mayor interés de la audiencia. La metodología empleada es cuantitativa y cualitativa a partir del análisis de cuentas en Facebook y Twitter de las estaciones. Las hipótesis son que la televisión social gana aceptación en los países del área andina y que los canales de televisión no explotan los medios sociales. Se concluye que las estaciones privadas muestran más actividad que las públicas, que existe diferencia entre los informativos y el entretenimiento en seguidores y actividad en la red y que estamos en el inicio de la televisión social pero demanda más esfuerzos para integrar pantallas y medios sociales.

    Full Text Available En los años recientes, varios países latinoamericanos han realizado importantes reformas a sus legislaciones relacionadas con la disciplina privada del contrato de seguro. Particularmente Chile y Perú procedieron a ello, en el primer caso, sustituyendo el capítulo correspondiente al contrato de seguro en su Código de Comercio de muy antigua vigencia, y en el segundo, expidiendo una ley específica sobre el tema. También países como México y Panamá, dentro del marco de sus normas de derecho público destinadas a regular la actividad financiera y de seguros, han expedido leyes nuevas relacionadas con la vigilancia y el control de la actividad aseguradora, que necesariamente se proyectan en mayor o menor medida sobre las relaciones particulares que surgen entre asegurados y aseguradores. El conocimiento de esas nuevas legislaciones es un elemento insustituible para la reforma que tarde o temprano deberá operarse sobre la nuestra que data ya de más de cuarenta años. Temas como la reticencia o inexactitud en la declaración del estado del riesgo, la agravación del riesgo, la imperatividad de las normas regulatorias del contrato, la identificación de las partes, la regulación de la oferta y de la etapa precontractual en el contrato de seguro, y muchas otras, son objeto de análisis y comentario en este artículo.

  2. Farming or seasonal migration? - Potential futures of reindeer husbandry in Fennoscandia studied with Social-Ecological System (SES) approach, co-production of knowledge, and scenarios

    The area allocated for reindeer husbandry in Finland, Sweden and Norway covers approximately 40 % of each country. As the livelihood requires large, relatively unfragmented territories while being marginal in terms of direct income, land-use conflicts between various livelihoods and activities, such as forestry, agriculture, mining, energy production, tourism, and nature protection are common phenomena in the region. Simultaneously, rapid societal change, urban exodus and fading traditions as well as climate warming and subsequent ecosystem change may put the livelihood at stake. We have probed potential futures of reindeer husbandry in Northern Fennoscandia using the Social-Ecological System (SES) approach, knowledge co-production in stakeholder-scientist workshops in all three countries, and scenario building based on quantitative data and narratives. Regarding the future of the livelihood, we have identified some crucial components in the SES that are influential in determining the direction of development. We produced four potential pathways of future development and demonstrate that important factors controlling the direction of development include governance and actor relations. Governance is often considered distant and opaque by local stakeholders, fostering conflicts in land allocation, while unclear regulations at local level reinforce emerging conflict situations leading to distrust and restrained communication between the actors. Regionally, these conflicts may lead to decreased resilience and threaten the future of the livelihood altogether. Therefore, research should focus on supporting the reform process of institutional arrangements and governance mechanisms, and fostering co-design and co-production processes that ease distrust and improve resilience of the livelihood in multifunctional landscapes.

    Full Text Available OBJECTIVE: To assess the prevalence of preterm birth among low birthweight babies in low and middle-income countries. METHODS: Major databases (PubMed, LILACS, Google Scholar were searched for studies on the prevalence of term and preterm LBW babies with field work carried out after 1990 in low- and middle-income countries. Regression methods were used to model this proportion according to LBW prevalence levels. RESULTS: According to 47 studies from 27 low- and middle-income countries, approximately half of all LBW babies are preterm rather than one in three as assumed in studies previous to the 1990s. CONCLUSIONS: The estimate of a substantially higher number of LBW preterm babies has important policy implications in view of special health care needs of these infants. As for earlier projections, our findings are limited by the relative lack of population-based studies.OBJETIVO: Estimar la prevalencia de recién nacidos pre-término entre los recién nacidos de bajo peso al nacer de países de renta media o baja. MÉTODOS: En consulta a bases de datos (PubMed, LILACS, Google Scholar fueron procurados estudios sobre la prevalencia de recién nacidos a término y pre-término entre aquellos de bajo peso al nacer conducidos posteriores a 1990 en países emergentes. Modelos de regresión fueron usados para evaluar la proporción de acuerdo con las prevalencias de bajo peso. RESULTADOS: Con base en 47 estudios de 27 países emergentes, aproximadamente la mitad de todos los recién nacidos con bajo peso serían prematuros, y no uno de cada tres, como se estimó en estudios anteriores a la década de 1990. CONCLUSIONES: La estimación de números sustancialmente más altos de prematuros con bajo peso tiene importantes consecuencias en la planificación de salud, ya que tales recién nacidos demandan cuidados especiales.

    Whereas the topic of the 'cultural sensitivity' of healthcare systems has been addressed extensively in the US and the UK, literature on the subject in most European countries, specifically looking at the situation of Roma, is still scarce. Drawing on qualitative research conducted mainly in the city of Barcelona under the communicative approach with Roma subjects who have stable socioeconomic positions and higher cultural capitals (end-users, professionals of the healthcare system, and key informants of a regional policy oriented to the improvement of Roma living conditions), the present study aims to fill this gap. We explore the barriers that the Roma face in accessing the healthcare system, reflecting on how these barriers are accentuated by the existing anti-Roma prejudices and institutional arrangements that do not account for minority cultures. Our results point out a series of obstacles at two levels, in the interaction with healthcare professionals, and in relation to existing institutional arrangements, which prevent Roma families from having equal access to the healthcare system. Education stands up as a mechanism to contest anti-Roma sentiments among healthcare professionals.

    Weiss, Jonathan D.

    2005-11-15

    A fluorescent optical position sensor and method of operation. A small excitation source side-pumps a localized region of fluorescence at an unknown position along a fluorescent waveguide. As the fluorescent light travels down the waveguide, the intensity of fluorescent light decreases due to absorption. By measuring with one (or two) photodetectors the attenuated intensity of fluorescent light emitted from one (or both) ends of the waveguide, the position of the excitation source relative to the waveguide can be determined by comparing the measured light intensity to a calibrated response curve or mathematical model. Alternatively, excitation light can be pumped into an end of the waveguide, which generates an exponentially-decaying continuous source of fluorescent light along the length of the waveguide. The position of a photodetector oriented to view the side of the waveguide can be uniquely determined by measuring the intensity of the fluorescent light emitted radially at that location.

    The present invention provides a device capable of measuring accurate position and distance easily even at places where operator can not easily access, such as cell facilities for vitrifying radioactive wastes. Referring to a case of the vitrifying cell, an objective equipment settled in the cell is photographed by a photographing device. The image is stored in a position measuring device by way of an image input device. After several years, when the objective equipment is exchanged, a new objective equipment is photographed by a photographing device. The image is also stored in the position measuring device. The position measuring device compares the data of both of the images on the basis of pixel unit. Based on the image of the equipment before the exchange as a reference, extent of the displacement of the installation position of the equipment on the image after the exchange caused by installation error and manufacturing error is determined to decide the position of the equipment after exchange relative to the equipment before exchange.

    We examined (1) the relationship that parental objective social status (OSS) and subjective social status (SSS) have with children's health-related quality of life (HRQOL), (2) whether SSS mediates the association between OSS and HRQOL, and (3) whether these associations differ among Black, Latino, and White children. Data came from 4,824 Black, Latino, and White 5th graders in the Healthy PassagesTM study. OSS was measured as parent educational attainment and net equivalent household income. SSS was measured by parent rating of community and national standing on the MacArthur Scale of Subjective Social Status. Child HRQOL was measured with child report on the Pediatric Quality of Life Inventory (PedsQL) physical and psychosocial scales. Structural equation modeling path analysis was conducted using Mplus version 7.4. The data supported the hypothesized measurement and structural models. Whereas parental OSS was positively related to psychosocial HRQOL for all three racial/ethnic groups and to physical HRQOL for Latino children, parental SSS was not related to either for any of the racial/ethnic groups. Therefore, mediation by SSS was not supported for any group. OSS was confirmed to have stronger association with children's HRQOL than parental SSS. This is in contrast to some research on adults, raising the questions of how best to assess SSS relevant to children and at what point in development SSS may influence children's health and well-being. The persistent relationship found between parental OSS and child health suggests that efforts to improve low socioeconomic resources in families may contribute to improve children's health.

    2015-07-01

    Does the socioeconomic status (SES) that one's (ego's) network members (alters) occupy indicate social resources or social comparison standards in the dynamics of health across culture? Using nationally representative data simultaneously collected from the United States and urban China, this study examines two competing theories-social capital and comparative reference group-in the two societies and compares their different application across the two societies using two cultural explanations, relational dependence and self-evaluation motive. Social capital theory expects absolute accessed SES and the size of higher accessed socioeconomic positions to protect health, and the size of lower accessed socioeconomic positions to harm health. But comparative reference group theory predicts the opposite. Additionally, the relational dependence explanation anticipates social capital theory to be more applicable to urban China and comparative reference group theory to be more applicable to the United States. The self-evaluation motive explanation expects the same pattern across the two societies in the examination of the size of lower accessed socioeconomic positions but the opposite pattern in the analysis of absolute accessed SES and the size of higher accessed socioeconomic positions. This study focuses on depressive symptoms and measures accessed occupational status. Results are consistent with the self-evaluation motive explanation. They support both social capital theory and comparative reference group theory in the United States but only the latter theory in urban China. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available Objective. To analyze the effects of socioeconomic, regional, and ethnic conditions on chronic malnutrition in four Andean countries of South America: Bolivia, Colombia, Ecuador, and Peru. Methods. The study was based on Demographic and Health Surveys (DHS for Colombia (1995, Peru (1996, and Bolivia (1997, and on a Living Standard Measurement Survey for Ecuador (1998. We developed an index of household socioeconomic status using categorical principal components analysis. We broke down the prevalence of stunting by socioeconomic status (SES, ethnicity, place of residence (large cities, small cities, towns, and countryside, and region (highland region versus other areas of the country. We applied smoothed regression curves and linear functions to analyze SES effects on stunting, with specific models for Bolivia, Ecuador, and Peru. Results. Bolivia, Ecuador, and Peru have similar characteristics, with high stunting prevalences overall; higher stunting prevalences in their highland areas, particularly among indigenous populations; and strong socioeconomic disparities. Colombia, in contrast, has a lower stunting prevalence and smaller regional disparities. The socioeconomic gradient of stunting is strong in all four countries, with prevalence rates in the poorest deciles at least three times as high as those in the top decile. Discussion. The sharp contrast between the conditions found in Bolivia, Ecuador, and Peru and those in Colombia may be the result of specific ethnic factors affecting indigenous groups; a particular diet profile in the highland areas, with low protein and micronutrient intake; and differences in the long-term economic and social development paths that the countries have taken. Along with the strong socioeconomic gradient in all the countries, the weight of ethnic and regional factors suggests the need to reduce inequality as well as to comprehensively improve education and housing, better target health and nutrition programs

    Purpose: To conduct position control stably to various plasmas and reduce the burden on the control coil power source. Constitution: Among the proportional, integration and differentiation controls, a proportional-differentiation control section and an integration control section are connected in parallel. Then, a signal switching circuit is disposed to the control signal input section for the proportional-differentiation control section such that either a present position of plasmas or deviation between the present plasma position and an aimed value can be selected as a control signal depending on the control procedures or the state of the plasmas. For instance, if a rapid response is required for the control, the deviation between the present plasma position and the aimed value is selected as the input signal to conduct proportional, integration and differentiation controls. While on the other hand, if it is intended to reduce the burden on the control coil power source, it is adapted such that the control signal inputted to the proportional-differentiation control section itself can select the present plasma position.

    An uncharged positive-electrode composition contains particulate lithium sulfide, another alkali metal or alkaline earth metal compound other than sulfide, e.g., lithium carbide, and a transition metal powder. The composition along with a binder, such as electrolytic salt or a thermosetting resin is applied onto an electrically conductive substrate to form a plaque. The plaque is assembled as a positive electrode within an electrochemical cell opposite to a negative electrode containing a material such as aluminum or silicon for alloying with lithium. During charging, lithium alloy is formed within the negative electrode and transition metal sulfide such as iron sulfide is produced within the positive electrode. Excess negative electrode capacity over that from the transition metal sulfide is provided due to the electrochemical reaction of the other than sulfide alkali metal or alkaline earth metal compound.

    A plurality of magnetically operated switches are spaced equally in the hollow tube of a control rod actuating mechanism. One side of each switch is connected, via a low resistance, to a corresponding tap of a low resistance voltage divider network consisting of an equivalent number of low resistance sections with the opposite side of each switch connected to a common conducting wire A. To both ends of the voltage dividing network are connected, respectively, conducting wires B and C. Wires A, B, and C are further coupled to a fuel rod position indicator comprising a voltmeter and power source external to the control rod actuating member. The control rod actuating member is adapted to slide in the hollow tube so that switches passing a position facing a magnet secured to the lower end of the actuating member are rendered closed. Hence, the position of the control rod may be read by reading the voltage off the meter.

    2017-09-01

    The EFT coefficients in any gapped, scalar, Lorentz invariant field theory must satisfy positivity requirements if there is to exist a local, analytic Wilsonian UV completion. We apply these bounds to the tree level scattering amplitudes for a massive Galileon. The addition of a mass term, which does not spoil the non-renormalization theorem of the Galileon and preserves the Galileon symmetry at loop level, is necessary to satisfy the lowest order positivity bound. We further show that a careful choice of successively higher derivative corrections are necessary to satisfy the higher order positivity bounds. There is then no obstruction to a local UV completion from considerations of tree level 2-to-2 scattering alone. To demonstrate this we give an explicit example of such a UV completion.

    Full Text Available OBJECTIVES: This article reports the prevalence of two types of interpersonal violence (IPV (sexual and physical and one type of aggression (psychological in three low-to-middle-income Caribbean countries. It examines IPV among adolescents and young adults as both victims and perpetrators. METHODS: This population-based study compares the experiences of 15-30 year olds in countries at different levels of socioeconomic development. The Revised Conflict Tactics Scales (CTS2 and other behavioral instruments were used to assess the level and characteristics of IPV. RESULTS: Out of 3 401 respondents, 70.9% reported victimization by some form of violence, which was most commonly perpetrated by a relationship partner (62.8%. Sexual violence victimization was reported more commonly by women, and was highest in Jamaica. Significant between-country differences in overall levels of reported physical violence, and psychological aggression, were evident when stratifying by perpetrator type. CONCLUSIONS: The very high levels of reported IPV indicate very high levels of tolerance among victims, and suggest a culture of violence and of adversarial intimate relationships may be well entrenched. The findings support the view that co-occurrence of general interpersonal violence and partner violence may be limited, and that one may not necessarily be a predictor of the other. They also reveal that, among partners, not only are there no gender differentials in victimization by physical violence, but more women than men are self-reporting as perpetrators of this type of IPV.OBJETIVOS: Se informa la prevalencia de dos formas de violencia interpersonal (VIP -la sexual y la física- y de un tipo de agresión -la psicológica- en tres países del Caribe de bajo a mediano ingresos. Se analiza la VIP entre adolescentes y adultos jóvenes, ya sea como víctimas o agresores. MÉTODOS: En este estudio basado en la población se comparan las experiencias de personas de 15 a 30

    Full Text Available The need for shelter is a growing worldwide problem. In developing countries this need far exceeds the capacity of government agencies to respond. Cooperative self-help techniques often provide alternative means for lower income people to imporve their own shelter and community services with a minimun of outside assistance. These techniques may often require the introduction of less advanced, but appropriate building technology is important. It is, however, only one part of a comprehensive system needed to produce better housing. In many countries, technology is the least important constraint; more serious concerns are building technology is important. It is, however, only one part of a comprehensive system needed to produce better housing. In many countries, technology is the least important constraint; more serious concerns are managerial and financial obstacles. The Building Materials Production Centers concept is part of a larger shelter development strategy; a "Cooperative Development System 1 aimed at promoting low-cost housing in developing countries. The self-help construction that takes place in squatter settlements and rural areas is often poorly served by the formal construction industry material suppliers and must rely on informal material production systems for building materials. Building Materials Production Centers can be established to meet the needs of these settlement areas in a more efficient way at a reasonable cost and at locations where people are improving their own housing and communities.

    2008-03-01

    The role of chromatin structure in gene regulation has recently taken center stage in the field of epigenetics, phenomena that change the phenotype without changing the DNA sequence. Recent work has also shown that nucleosomes, a complex of DNA wrapped around a histone octamer, experience a sequence dependent energy landscape due to the variation in DNA bend stiffness with sequence composition. In this talk, we consider the role nucleosome positioning might play in the formation of heterochromatin, a compact form of DNA generically responsible for gene silencing. In particular, we discuss how different patterns of nucleosome positions, periodic or random, could either facilitate or suppress heterochromatin stability and formation.

Inicialmente, os objetivos da política cambial são discutidos, enfatizando sua importância como instrumento gerador de crescimento econômico. Dando continuidade, alguns canais de influência do nível da taxa de câmbio sobre o crescimento econômico são apontados: (i os canais do investimento; (ii da exportação dos bens não tradicionais; (iii do desempenho do setor de bens comercializáveis; (iv da compensação às falhas de mercado e falhas contratuais; e (v de estímulo às elasticidades-renda das exportações. Na parte empírica, uma medida de subvalorização cambial é construí-da para 82 países em desenvolvimento entre 1980 e 2007. Essa medida é empregada para captar a relação entre taxa de câmbio desvalorizada e crescimento econômico. Os resultados indicam uma correlação positiva e significante entre a medida de subvalorização cambial construída e o crescimento econômico nos países que fazem parte da amostra.The article analyses, theoretically and empirically, the relationship between exchange rate level and economic growth in emerging and developing countries. Firstly, the exchange rate policy objectives are discussed, emphasizing the importance of this policy to generate economic growth. Continuing, the article explores the channels through which exchange rates can affect economic growth, highlighting its stimulus to investment, export of non-traditional goods, productivity as well as its compensation to market failures and its stimulus to export income-elasticity. In the empirical part, a measure of exchange rate undervaluation based on Rodrik (2007 is built for 82 emerging and developing countries, between 1980 and 2007.

This paper shows the results obtaind in the study of the Netherlands, a country so many times regarded as a referencen in democracy (and so in culture of peace in Europe. Culture of peace is a project defended and promoted by UNESCO, vertebrated in a whole theoretical and conceptual universe, that not only means the absense of war, but focuses all kind of human and social relationships. In order to this purpose, we have analyzed carefully the whole 26 Government’s campaigns. Los últimos años los he dedicado a estudiar el fomento de la cultura de paz a través de la publicidad institucional que la Administración General del Estado (España contrataba para televisión. Año tras año, veía que los resultados eran los mismos, así que decidí investigar qué sucedía a propósito del mismo fenómeno, en otros países. Este texto presenta los resultados obtenidos sobre el caso de los Países Bajos, un estado que en muchos casos ha sido referente de los valores democráticos (y por ende de la cultura de paz en Europa. En este artículo se describe y analiza la publicidad institucional del estado neerlandés en el fomento de la cultura de paz. La cultura de paz es un proyecto defendido promovido por la UNESCO, vertebrado en todo un universo teórico y conceptual, que no se refiere únicamente a la paz como ausencia de guerra, sino que incide en todas las formas de relaciones humanas y sociales.

Inicialmente, são apresentadas as principais causas do aquecimento terrestre e como a utilização de combustíveis fósseis amplia o efeito estufa. Em seguida, são estimadas as emissões de CO2 para três cenários alternativos utilizando-se da Identidade de Kaya. Nos três cenários foram considerados que o aumento populacional e o crescimento da economia seguiriam as taxas médias do período 2000-05. Tentou-se avaliar os efeitos da redução dos índices de intensidade energética e de CO2, mantida a mesma taxa de crescimento econômico e populacional. Neste sentido, nem mesmo no cenário no qual é previsto um maior uso de energias renováveis e de tecnologias voltadas à proteção do meio ambiente, foi possível reduzir os níveis de emissões de CO2 em todos os países.Abstract The main aim of this paper is to evaluate the emissions of carbon dioxide in 2012 as consequence of economic activities in developing countries (South Africa, Argentina, Brazil, China, India and Mexico.

Con el objetivo de conocer dónde se ubica la responsabilidad para la realización de diferentes tipos de actividades preventivas, se realizó una encuesta en ocho áreas geográficas de seis países de Europa y Norteamérica. Métodos: Encuesta entre expertos basada en una matriz que relaciona servicios sanitarios preventivos con la población a la que se dirigen. Se establecieron ocho situaciones clínicas (vacunaciones infantiles y antigripal adultos; y detección precoz: de cáncer mediante mamografía, de tuberculosis, de Hipertensión Arterial, de fenilcetonuria, del virus de la inmunodeficiencia humana, y de osteoporosis, con el fin de conocer en relación a las mismas la población diana, nivel de establecimiento de las políticas, nivel de contacto con los individuos, seguimiento de los individuos con diagnósticos positivos y registro de sus datos clínicos. Resultados: Este estudio piloto mostró muy escasa coincidencia de los resultados tanto entre las ocho áreas encuestadas como en cada una de ellas. No se encontró un patrón regular para las actividades de prevención exploradas entre los diferentes países, ni en función de la tipología de sus sistemas sanitarios, ni por la orientación hacia la atención primaria de los diferentes sistemas. Conclusiones: Existe un escaso consenso en las áreas estudiadas en relación con la mejor forma de realizar las intervenciones de salud pública que conllevan prestación de atención sanitaria personal.

En Georgia y Letonia el 100% de los casos de SIDA se da entre personas con edades comprendidas entre los 15 y los 49 años. En España el 90% de los casos también se da en este rango de edad. Rumanía es el país con mayor porcentaje de casos de niños con SIDA y posee además un alto porcentaje de mujeres con la enfermedad. En Bulgaria se da un predominio de la transmisión heterosexual (93% y en Hungría predomina la homosexual (74%. Las conclusiones más relevantes son que las vías más importantes de transmisión del VIH/SIDA en Europa son el consumo de drogas por vía parenteral y las relaciones homosexuales. Para la lucha contra el SIDA se deben realizar medidas de prevención dirigidas sobre todo a los jóvenes, puesto que la mayoría de las infecciones tiene lugar durante o poco después de la adolescencia.

    Full Text Available Esta pesquisa objetivou identificar a existência de relações entre as variáveis: nível de independência e nível de atuação de uma Instituição Superior de Auditoria e o nível de transparência de uma nação, utilizando a técnica de regressão logística binária. A amostra estudada foi composta por dados de 85 países, obtidos da base de dados do Open Budget Initiative 2008. Apenas a variável nível de atuação foi considerada significativa, não sendo possível identificar a existência de relação entre o nível de independência e o nível de transparência fiscal. O modelo resultante da regressão logística binária apresentou probabilidade de correta classificação de 92,9%. Considerando-se as duas categorias do modelo, baixo ou regular e bom nível de transparência a percentagem de correta classificação foi de 94,7% e 50,0%, respectivamente. Estas constatações validaram parcialmente a hipótese de que bom nível de independência e bom nível de atuação de uma instituição Superior de Auditoria estão associados a um bom nível de transparência fiscal, propiciando a afirmação de que nos países em que as Instituições Superiores de Auditoria são atuantes, os gestores se pré-dispõem a utilizar práticas relacionadas com a transparência fiscal.

Las simulaciones muestran que en países con alta mortalidad, v.g.

Este ejercicio teórico muestra en todas las simulaciones que el tamaño de la población de los países de América Latina, que iniciaron su transición demográfica décadas atrás, no experimentará un crecimiento considerable. La población de Brasil y de Argentina, aún al alcanzar su límite teórico, no se duplicará. A pesar de que el límite teórico de las poblaciones analizadas se alcanzará en 400 a 500 años, éstos alcanzarán un estado “cuasi-estable” entre los años 2050 y 2100.

    This study investigated how trilinguals fare on the cross-linguistic lexical tasks (CLT)-Afrikaans, -isiXhosa and -South African English (SAE) (cf. Haman et al., 2015) compared to monolingual controls, and whether the CLT-Afrikaans renders comparable results across socioeconomic status (SES) backgrounds. The LITMUS-CLTs were administered to 41 low SES 4-year-olds (11 trilinguals; 10 monolingual speakers of Afrikaans, isiXhosa and SAE) and the LITMUS-CLT-Afrikaans to 11 mid-SES 4-year-old monolinguals. Results (a) indicate that trilinguals' proficiency in their exposure-dominant language did not differ significantly from monolinguals' proficiency, but their proficiency in their additional two languages was significantly lower than monolinguals' proficiency; (b) reflect the extent, but not current amount, of exposure trilinguals had had over time to each of their languages; and (c) show that low and mid-SES monolinguals differed significantly on noun-related, but not verb-related, CLT measures. Possible reasons for and the clinical implications of these results are discussed.

These themes are approached by Positive Psychology, with Seligman like the principal exponent. Psychology was dedicated to explore the negative aspects from human beings improving human health. Nevertheless, this pathogenic model could not prevent mental disease. Concepts of Positive Psychology have a solid antecedent in Víktor Frankl ́s studies, which is the Logotherapy founder. This allows incorporating another perspective to approach positive aspects, from a philosophical and anthropological focus. Although the ways adopted by Frank and Seligman are different, both considered main aspects of human existence. Nevertheless, they investigated in different countries (from Europe and EE.UU.; in different circumstances (concentration camps, deaths, tortures; vs. academic context; in different historical periods and different social contexts (a country that lost the war and other that gave freedom to Europeans.

    2015-11-01

    Full Text Available As a Western feminist supporting and researching gender equality in education in postcolonial contexts, I often wonder: Am I doing more harm than good? The privilege of my social location means that my efforts to support education in postcolonial contexts risk being patronizing, insulting, threatening, imperialist, and recolonizing. Yet neglecting and ignoring postcolonial contexts similarly reflects and reproduces a privileged position. I provide a tentative framework designed to address positionality, power, and privilege while creating an ethical research process for working in a postcolonial context. Beginning with an identification of positionality, the objectives of research, and guiding theoretical frameworks to situate the research in relation to the participants and context, I proceed to establish a methodology designed to minimize the negative effects of power and maximize participants’ empowerment. I position myself as a bricoleur, layering feminist standpoint theory and postcolonial theory, and propose the collaborative data collection and analysis techniques, with particular attention to ethical and cultural sensitivity, using a social constructivist approach to grounded theory. This article highlights the need for Western researchers to reflect upon the power dynamics of their research in postcolonial contexts and develop a strategy for conducting empowering research that prevents the misrepresentation and exploitation of participants. Observations from my doctoral thesis data collection provide examples of how these concepts were operationalized in practice as well as reflections on the disconnect between theorizing and conducting ethical research in postcolonial contexts.

Presentamos un modelo conjunto de elección discreta y, de acuerdo con éste, postulamos y estimamos una función de utilidad cuadrática. A partir de los parámetros estimados calculamos las elasticidades de la oferta laboral respecto al ingreso no laboral. También simulamos una política de bienestar común inspirada en el “Plan jefe de hogar” de Argentina. Entre los resultados obtenidos destaca un rendimiento de la educación de entre el 6.6 y el 10.7% para las mujeres casadas, así como un variado efecto de las mejoras en los ingresos no laborales en las decisiones de oferta laboral. Esta diversidad es un reflejo de la heterogeneidad de estos países desde el punto de vista de la polarización de las condiciones so-cioeconómicas y laborales.

    Childhood maltreatment is associated with risk for suicidal ideation later in life, yet more research is needed on the indirect effects and bioregulatory protective factors in this association. The present study aimed to investigate the indirect influence of childhood maltreatment on suicidal ideation in emerging adulthood via level of self-esteem, and examine the moderating role of heart rate variability (HRV; a proxy for emotion regulation) in this indirect association. The study included a sample of 167 non-metropolitan emerging adults (M age  = 21.17, 55.8% female) of low-socioeconomic status (low-SES). HRV data were obained using an electrocardigram, whereas childhood maltreatment, suicidal ideation, and self-esteem data were obtained via self-report. Childhood maltreatment was indirectly associated with suicidal ideation via reduced self-esteem. HRV buffered this indirect association. Childhood maltreatment poses a risk for the development of suicidal ideation. Interventions that bolster self-esteem and emotion regulation may reduce suicide risk for emerging adults with a history of childhood maltreatment.

Este artículo plantea que el nudo gordiano de esa paradoja es la gran desigualdad en la distribución del ingreso. Causa y consecuencia del mal funcionamiento del sistema político y de la economía, porque las élites económicas controlan el poder político, y crean instituciones y políticas que reflejan el interés de los dueños de la riqueza y no el interés común. Así se crea un círculo vicioso en el que la democracia ¿controlada¿ reproduce y amplía las desigualdades que la engendraron.

    1994-01-01

    Full Text Available La transición al mercado ha sido para los países del Este de Europa el paso de la euforia inicial al desengaño generalizado. Las medidas adoptadas por los nuevos dirigentes con el propósito de reanimar la economía y sacarla de la crisis han conducido a lo contrario: la caída de la producción, la aparición del desempleo y el desplome del nivel de vida. Esta situación lleva al autor a través del artículo y a la luz de los acontecimientos recientes en la región, que han conducido a una modificación de las formas de propiedad dominantes existentes durante el período del socialismo real, a plantear la necesaria redefinición del marco socio-institucional que conduzca no sólo al desmonte del sistema centralista-burocrático de gestión, sino que se dirija también, y ésto es lo fundamental, al normal funcionamiento de una economía de mercado. Es esto último lo que el artículo se encarga de desglosar mientras explica, en ese nuevo contexto, los cambios que se deben realizar tanto en el factor humano corno en los sistemas legal y contable.

    The carboxylesterase-encoding gene (bioHs) of a newly isolated strain, Serratia sp. SES-01, was cloned from the genomic DNA library by detecting formation of transparent halo around the colony on LB-tributyrin agar plates. The amino acid sequence of BioHs was highly similar to the members of the BioH enzyme family involved in the biotin biosynthetic pathway; it showed the highest similarity (91%) with that of Serratia proteamaculans. To compare BioHs with other BioH enzymes, the relatively well-known bioHe gene of E. coli was cloned with PCR. After we achieved high-level expression of soluble BioHs and BioHe through the exploration of different culture conditions, the purified BioHs and BioHe enzymes were characterized in terms of specificity, activity, and stability. BioHe was generally more robust to a change in temperature and pH and an addition of organic solvents than BioHs. The two enzymes exhibited a strong preference for carboxylesterase rather than for thioesterase and were optimal at relatively low temperatures (20-40 degrees ) and alkaline pHs (7.5-9.0). The results in this study strongly suggested that both the BioHs and BioHe enzymes would be potential candidates for use as a carboxylesterase in many industrial applications.

En esta visión, el poder efectivo de dicha entidad política se está desbordando en tres direcciones: hacia arriba, por la globalización y la supranacionalización; horizontalmente, por el desmonte del Estado de bienestar, la privatización y la desregulación; y hacia abajo, por la descentralización y la devolución de autonomías a las polis regionales y locales. La acción conjunta de estas tendencias estaría determinando el vaciamiento (hollowing out del Estado-nación, en la medida en que muchas de sus competencias tradicionales se están transfiriendo hacia arriba, a las instituciones internacionales y supranacionales; hacia los lados, al mercado, las empresas privadas y las transnacionales; y hacia abajo, a las entidades de orden subnacional.

    La coordination de sécurité pour l'installation du LHC et de ses expériences a été mise en place lors du démantèlement du LEP. Depuis, les contractants et les surveillants de chantier ont fait beaucoup de progrès en matière de sécurité et les procédures en vigueur sont maintenant suivies. Néanmoins, des accidents et incidents se produisent encore et pourraient être facilement évités. Un incident important, des dommages sérieux aux équipements, ou pire un accident mortel affecteraient sérieusement le projet LHC. L'analyse des causes des accidents récents révèle toujours une marge d'amélioration, en particulier en ce qui concerne l'analyse à priori des procédures l'installation et des méthodes de travail.

    Full Text Available Este estudio busca analizar las relaciones entre los componentes de la identidad nacional, la ideología política, en sus manifestaciones autoritaria y de dominancia social, y las expresiones del bienestar subjetivo y social en muestras de 5 países de América Latina. Para tal fin, se desarrolló un estudio por encuestas en Brasil, Chile, Colombia, México y Perú (n=1039. Los resultados evidencian relaciones significativas entre las expresiones ideológicas con algunas dimensiones de la identidad. La ideología autoritaria se relaciona positivamente con los componentes identitarios, mientras que la ideología de dominancia social lo hace en menor medida y de manera inversa. Las relaciones entre los componentes de la identidad y el bienestar presentan un asociación positiva, y estas relaciones son más intensas en el caso del bienestar social que en el caso del bienestar subjetivo aunque cierta heterogeneidad por país también es observada. Se intentó proponer un modelo general de las relaciones entre las variables derivadas de los tres constructos pero esta no alcanzó buenos niveles de ajuste, lo que se explicaría por la heterogeneidad de los resultados obtenidos por país.

  6. Net positive energy buildings

    International Nuclear Information System (INIS)

    Romero, A.; Barreiro, E.; Sanchez Zabala, V.

    2010-01-01

    Buildings are great consumers of energy, being responsible for almost 36% of CO2 emissions in Europe. Though there are many initiatives towards the reduction of energy consumption and CO2 emissions in buildings, many of the alternatives are diminished due to a lack of a unique and holistic approach to the problem. This paper reports a new innovative concept of Positive Energy Buildings (EB+), as well as an integral methodology that covers the overall design process for achieving them. The methodology evaluates energy efficiency solutions at different scales, from building site to generation systems. An educational building design in Navarra serves as a case study to check the feasibility of the proposed methodology. The study concludes that the key to achieve a Positive Energy Building is a minimized energy demand, complemented by efficient facilities and enhanced by distributed power generation from renewable sources.

Drawing from different case studies, it contains analyses of how subjects identifying with different political actors in the Basque...... conflict adopted their respective positions, and interpretation of the conflict, and how, in light of same, they reconstruct the failed peace process that took place in 2006 between the terrorist group ETA (Euzkadi ta Azcatasuna, or Basque Country and Freedom in English) and the Spanish government. Results...... show that the positioning adopted by participants gives rise to a certain form of interpreting the conflict, which, in turn, affects how the peace process is remembered. This occurs within a particular argumentative context in which each version constitutes an implicit response to a competing...

    We show that the naive positivity conditions on polarized parton distributions which follow from their probabilistic interpretation in the naive parton model are reproduced in perturbative QCD at the leading log level if the quark and gluon distribution are defined in terms of physical processes. We show how these conditions are modified at the next-to-leading level, and discuss their phenomenological implications, in particular in view of the determination of the polarized gluon distribution

    1995-01-01

    A photon beam position monitor for use in the front end of a beamline of a high heat flux and high energy photon source such as a synchrotron radiation storage ring detects and measures the position and, when a pair of such monitors are used in tandem, the slope of a photon beam emanating from an insertion device such as a wiggler or an undulator inserted in the straight sections of the ring. The photon beam position monitor includes a plurality of spaced blades for precisely locating the photon beam, with each blade comprised of chemical vapor deposition (CVD) diamond with an outer metal coating of a photon sensitive metal such as tungsten, molybdenum, etc., which combination emits electrons when a high energy photon beam is incident upon the blade. Two such monitors are contemplated for use in the front end of the beamline, with the two monitors having vertically and horizontally offset detector blades to avoid blade "shadowing". Provision is made for aligning the detector blades with the photon beam and limiting detector blade temperature during operation.

    Smith, Stephen R.

    1996-07-01

    The design of beam position monitors often involves challenging system design choices. Position transducers must be robust, accurate, and generate adequate position signal without unduly disturbing the beam. Electronics must be reliable and affordable, usually while meeting tough requirements on precision. accuracy, and dynamic range. These requirements may be difficult to achieve simultaneously, leading the designer into interesting opportunities for optimization or compromise. Some useful techniques and tools are shown. Both finite element analysis and analytic techniques will be used to investigate quasi-static aspects of electromagnetic fields such as the impedance of and the coupling of beam to striplines or buttons. Finite-element tools will be used to understand dynamic aspects of the electromagnetic fields of beams, such as wake-fields and transmission-line and cavity effects in vacuum-to-air feed through. Mathematical modeling of electrical signals through a processing chain will be demonstrated, in particular to illuminate areas where neither a pure time-domain nor a pure frequency-domain analysis is obviously advantageous. Emphasis will be on calculational techniques, in particular on using both time-domain and frequency domain approaches to the applicable parts of interesting problems

    The (x, y) position reconstruction method used in the analysis of the complete exposure of the Large Underground Xenon (LUX) experiment is presented. The algorithm is based on a statistical test that makes use of an iterative method to recover the photomultiplier tube (PMT) light response directly from the calibration data. The light response functions make use of a two dimensional functional form to account for the photons reflected on the inner walls of the detector. To increase the resolution for small pulses, a photon counting technique was employed to describe the response of the PMTs. The reconstruction was assessed with calibration data including 83mKr (releasing a total energy of 41.5 keV) and 3H (β- with Q = 18.6 keV) decays, and a deuterium-deuterium (D-D) neutron beam (2.45 MeV) . Within the detector's fiducial volume, the reconstruction has achieved an (x, y) position uncertainty of σ = 0.82 cm and σ = 0.17 cm for events of only 200 and 4,000 detected electroluminescence photons respectively. Such signals are associated with electron recoils of energies ~0.25 keV and ~10 keV, respectively. The reconstructed position of the smallest events with a single electron emitted from the liquid surface (22 detected photons) has a horizontal (x, y) uncertainty of 2.13 cm.

    Full Text Available OBJECTIVE: To describe the effects of social inequities on the health and nutrition of children in low and middle income countries. METHODS: We reviewed existing data on socioeconomic disparities within-countries relative to the use of services, nutritional status, morbidity, and mortality. A conceptual framework including five major hierarchical categories affecting inequities was adopted: socioeconomic context and position, differential exposure, differential vulnerability, differential health outcomes, and differential consequences. The search of the PubMed database since 1990 identified 244 articles related to the theme. Results were also analyzed from almost 100 recent national surveys, including Demographic Health Surveys and the UNICEF Multiple Indicator Cluster Surveys. RESULTS: Children from poor families are more likely, relative to those from better-off families, to be exposed to pathogenic agents; once they are exposed, they are more likely to become ill because of their lower resistance and lower coverage with preventive interventions. Once they become ill, they are less likely to have access to health services and the quality of these services is likely to be lower, with less access to life-saving treatments. As a consequence, children from poor family have higher mortality rates and are more likely to be undernourished. CONCLUSIONS: Except for child obesity and inadequate breastfeeding practices, all the other adverse conditions analyzed were more prevalent in children from less well-off families. Careful documentation of the multiple levels of determination of socioeconomic inequities in child health is essential for understanding the nature of this problem and for establishing interventions that can reduce these differences.OBJETIVO: Describir el efecto de las iniquidades sociales sobre la nutrición y salud de niños de países de renta baja y media.

    We generalize the so-called 'deflected anomaly mediation' scenario to the case where threshold corrections of heavy messengers to the sparticle squared masses are positive. A concrete model realizing this scenario is also presented. The tachyonic slepton problem can be fixed with only a pair of messengers. The resultant sparticle mass spectrum is quite different from that in the conventional deflected anomaly mediation scenario, but is similar to the one in the gauge mediation scenario. The lightest sparticle is mostly B-ino

    Full Text Available This paper presents ongoing work on localization and positioning through triangulation procedure for a Fixed Sensors Network - FSN.The FSN has to work as a system.As the triangulation problem becomes high complicated in a case with large numbers of sensors and transmitters, an adequate grid topology is needed in order to tackle the detection complexity.For that reason a Network grid topology is presented and areas that are problematic and need further analysis are analyzed.The Network System in order to deal with problems of saturation and False Triangulations - FTRNs will have to find adequate methods in every sub-area of the Area Of Interest - AOI.Also, concepts like Sensor blindness and overall Network blindness, are presented. All these concepts affect the Network detection rate and its performance and ought to be considered in a way that the network overall performance won’t be degraded.Network performance should be monitored contentiously, with right algorithms and methods.It is also shown that as the number of TRNs and FTRNs is increased Detection Complexity - DC is increased.It is hoped that with further research all the characteristics of a triangulation system network for positioning will be gained and the system will be able to perform autonomously with a high detection rate.

    Full Text Available Dos funciones esenciales de los programas de vacunación regionales aplicados en varios países simultáneamente consisten en controlar en todo un territorio, franqueando fronteras, las enfermedades que se pueden prevenir mediante la vacunación y en reducir las faltas de equidad en materia de salud. Los buenos resultados de los programas de vacunación regionales dependen del esfuerzo coordinado que hagan los países y sus socios por alcanzar una meta regional en común. Con el fin de explorar las lecciones derivadas de la experiencia, en este artículo se echa un vistazo al Programa Ampliado de Inmunización original de la Organización Panamericana de la Salud (OPS, al Fondo Rotatorio de la OPS para la adquisición de vacunas y jeringas para los programas nacionales de vacunación, y a la erradicación de la poliomielitis del territorio americano. Se resaltan estas lecciones para ayudar a los formuladores de políticas en los niveles mundial, regional y subregional a coordinar eficazmente las intervenciones de salud realizadas por varios países en conjunto. Para ser provechosos, los programas de salud regionales tienen que verse respaldados por un genuino compromiso con la cooperación entre países como valor fundamental; la capacidad para averiguar qué problemas existen e idear buenas soluciones; la capacidad para llevar a cabo intervenciones de manera sustentable; el firme compromiso de los ministros de salud y otros jefes de gobierno; la gestión eficaz de los programas; los planes de salud nacionales; la buena supervisión técnica y la coordinación de alianzas; una cooperación técnica más intensa con los países más pobres, donde hay que redoblar los esfuerzos por conseguir más recursos y apoyo; la cooperación entre países; y la capacidad para responder a circunstancias insólitas.

Con el desarrollo de políticas restrictivas se incrementa la entrada y el trabajo clandestino de inmigrantes que de forma legal bien podrían contribuir económica, social y culturalmente a la UE. A lo largo de los años se han diseñado políticas de migración de provecho unilateral que hacen que Europa reciba los mayores beneficios generados del trabajo de inmigrantes de terceros países, y aunque existen iniciativas para facilitar la entrada legal y luchar contra la explotación de estas personas, es díficil que los Estados miembros lleguen a un acuerdo conjunto. Políticamente la migración es un tema muy delicado. Sin embargo, la fotaleza europea que tiene entre sus objetivos principales la libre circulación de personas y la garantía de los derechos de sus ciudadanos dentro de la UE, debería tomar en cuenta que un porcentaje significativo de su población está compuesta de personas provenientes de terceros países que igual que los ciudadanos europeos merecen ser respetados y tratados como seres humanos.ABSTRACT: The current European migration policy have a tendency to stimulate the migration of workers with high qualifications (brain drain and to discourage the migration of workers with less or no qualifications, those who when don’t find legal ways to work in the EU risk their lives trying to cross the borders clandestinely and carry out physical jobs, often, unhealthy, dangerous and unworthy.

    High-intensity focused ultrasound (HIFU) in combination with palliative standard therapy is an innovative and effective treatment option for pain reduction in patients with inoperable pancreatic cancer. Evaluation of the effects of additive ultrasound (US)-guided HIFU treatment in inoperable pancreatic cancer on the sensory and affective pain perception using validated questionnaries. In this study 20 patients with locally advanced inoperable pancreatic cancer and tumor-related pain were treated by US-guided HIFU (6 stage III, 12 stage IV according to UICC and 2 with local recurrence after surgery). Ablation was performed using the JC HIFU system (HAIFU, Chongqing, China) with an ultrasonic device for real-time imaging. Clinical assessment included evaluation of pain severity using validated questionnaires with particular attention to the pain sensation scale (SES) with its affective and sensory component and the numeric rating scale (NRS). The average pain reduction after HIFU was 2.87 points on the NRS scale and 57.3 % compared to the mean baseline score (n = 15, 75 %) in 19 of 20 treated patients. Four patients did not report pain relief, however, the previous opioid medication could be stopped (n = 2) or the analgesic dosage could be reduced (n = 2). No pain reduction was achieved in one patient. Furthermore, after HIFU emotional as well as sensory pain aspects were significantly reduced (before vs. 1 week after HIFU, p pain scales). US-guided HIFU can be used for effective and early pain relief and reduction of emotional and sensory pain sensation in patients with locally advanced pancreatic cancer.

    Full Text Available Researchers and practitioners often use standardized vocabulary tests such as the Peabody Picture Vocabulary Test-4 (PPVT-4; Dunn and Dunn, 2007 and its companion, the Expressive Vocabulary Test-2 (EVT-2; Williams, 2007, to assess English vocabulary skills as an indicator of children's school readiness. Despite their psychometric excellence in the norm sample, issues arise when standardized vocabulary tests are used to asses children from culturally, linguistically and ethnically diverse backgrounds (e.g., Spanish-speaking English language learners or delayed in some manner. One of the biggest challenges is establishing the appropriateness of these measures with non-English or non-standard English speaking children as often they score one to two standard deviations below expected levels (e.g., Lonigan et al., 2013. This study re-examines the issues in analyzing the PPVT-4 and EVT-2 scores in a sample of 4-to-5-year-old low SES Hispanic preschool children who were part of a larger randomized clinical trial on the effects of a supplemental English shared-reading vocabulary curriculum (Pollard-Durodola et al., 2016. It was found that data exhibited strong floor effects and the presence of floor effects made it difficult to differentiate the invention group and the control group on their vocabulary growth in the intervention. A simulation study is then presented under the multilevel structural equation modeling (MSEM framework and results revealed that in regular multilevel data analysis, ignoring floor effects in the outcome variables led to biased results in parameter estimates, standard error estimates, and significance tests. Our findings suggest caution in analyzing and interpreting scores of ethnically and culturally diverse children on standardized vocabulary tests (e.g., floor effects. It is recommended appropriate analytical methods that take into account floor effects in outcome variables should be considered.

    In most Western countries, the individual, social, and family characteristics associated with students' dropout in the general population are well documented. Yet, there is a lack of large-scale studies to establish whether these characteristics have the same influence for students with an immigrant background. The first aim of this study was to assess the differences between first-, second-, and third-generation-plus students in terms of the individual, social, and family factors associated with school dropout. Next, we examined the differential associations between these individual, social, and family factors and high school dropout as a function of students' immigration status. Participants were 2291 students (54.7% with an immigrant background) from ten low-SES schools in Montreal (Quebec, Canada). Individual, social, and family predictors were self-reported by students in secondary one (mean age = 12.34 years), while school dropout status was obtained five or 6 years after students were expected to graduate. Results of logistic regressions with multiple group latent class models showed that first- and second-generation students faced more economic adversity than third-generation-plus students and that they differed from each other and with their native peers in terms of individual, social, and family risk factors. Moreover, 40% of the risk factors considered in this study were differentially associated with first-, second-, and third-generation-plus students' failure to graduate from high school. These results provide insights on immigrant and non-immigrant inner cities' students experiences related to school dropout. The implications of these findings are discussed. © 2017 The British Psychological Society.

Thus, the level of asymmetry on recognition of good and bad news was analyzed applying the Basu model (1997. Results indicate a low relationship between current earnings and current stock returns. This fact can be explained by the relationship between corporate governance models and their relationship with the value-relevance of accounting information taking into account the institutional environment. It must be highlighted that an asymmetric recognition was observed between good and bad news, indicating a certain level of conservatism on accounting earnings.

    The ability to predict electro-optical (EO) signatures of diverse targets against cluttered backgrounds is paramount for signature evaluation and/or management. Knowledge of target and background signatures is essential for a variety of defense-related applications. While there is no substitute for measured target and background signatures to determine contrast and detection probability, the capability to simulate any mission scenario with desired environmental conditions is a tremendous asset for defense agencies. In this paper, a systematic process for the thermal and visible-through-infrared simulation of camouflaged human dismounts in cluttered outdoor environments is presented. This process, utilizing the thermal and EO/IR radiance simulation tool TAIThermIR (and MuSES), provides a repeatable and accurate approach for analyzing contrast, signature and detectability of humans in multiple wavebands. The engineering workflow required to combine natural weather boundary conditions and the human thermoregulatory module developed by ThermoAnalytics is summarized. The procedure includes human geometry creation, human segmental physiology description and transient physical temperature prediction using environmental boundary conditions and active thermoregulation. Radiance renderings, which use Sandford-Robertson BRDF optical surface property descriptions and are coupled with MODTRAN for the calculation of atmospheric effects, are demonstrated. Sensor effects such as optical blurring and photon noise can be optionally included, increasing the accuracy of detection probability outputs that accompany each rendering. This virtual evaluation procedure has been extensively validated and provides a flexible evaluation process that minimizes the difficulties inherent in human-subject field testing. Defense applications such as detection probability assessment, camouflage pattern evaluation, conspicuity tests and automatic target recognition are discussed.

    Full Text Available Esta investigación analiza la contribución del ciberactivismo al cambio político y social en Túnez, en Egipto y en Libia, y la opinión de los jóvenes árabes sobre la situación actual. Para disponer de información relevante sobre estos hechos se ha entrevistado periódicamente durante los últimos cinco años a 30 universitarios que ya habían participado en el proceso que impulsó las revueltas de 2011 y que siguen siendo ciberactivistas desde entonces. La utilización de una metodología mixta permite realizar un estudio donde los aspectos de carácter cuantitativo se complementan con contenidos cualitativos. Los resultados demuestran que los países árabes todavía no se han desprendido de muchas de las estructuras que sostenían a los regímenes anteriores a 2011, que son las que dificultan la consolidación de un sistema moderno. En este momento en Túnez, en Egipto y en Libia todavía conviven dos realidades que provocan un choque permanente entre las tradiciones milenarias, muy arraigadas en determinados sectores de la sociedad, y los valores asociados a las revoluciones, más progresistas. En un contexto donde es necesaria la unidad de acción, el ciberactivismo juega un papel fundamental porque congrega en un espacio virtual común a la ciudadanía crítica comprometida con el proceso de cambio, permite organizarse, mantener contacto con el exterior al margen de la censura oficial, hacer visibles las protestas en escenarios internacionales y vigilar las acciones del Gobierno.

    1992-09-01

    This report is a review of some of the important aspects of the analysis of large loss-of-coolant accidents (LOCAs). One important aspect is the calculation of positive void reactivity. To study this subject the lattice physics codes used for void worth calculations and the coupled neutronic and thermal-hydraulic codes used for the transient analysis are reviewed. Also reviewed are the measurements used to help validate the codes. The application of these codes to large LOCAs is studied with attention focused on the uncertainty factor for the void worth used to bias the results. Another aspect of the subject dealt with in the report is the acceptance criteria that are applied. This includes the criterion for peak fuel enthalpy and the question of whether prompt criticality should also be a criterion. To study the former, fuel behavior measurements and calculations are reviewed. (Author) (49 refs., 2 figs., tab.)

    Introduction/objective: The purpose of this study was to assess whether condylar position, as depicted by magnetic resonance imaging, was an indicator of disc morphology and position. Methods and material: One hundred and twenty two TMJs of 61 patients with temporomandibular joint disorder were examined. Condylar position, disc deformity and degree of anterior disc displacement were evaluated by using magnetic resonance imaging. Results and discussion: Posterior condyle position was found to be the main feature of temporomandibular joints with slight and moderate anterior disc displacement. No statistical significance was found between the condylar position, and reducing and nonreducing disc positions. On the other hand, superior disc position was found to be statistically significant for centric condylar position. Conclusion: It was concluded that posterior condyle position could indicate anterior disc displacement whereas there was no relation between the position of condyle and the disc deformity.

Después de haber hecho una extensiva investigación sobre AMT en la literatura, dos preguntas de investigación se formularon con respecto a las diferencias entre ambos países. Usando una metodología en forma de cuestionario, la información se recolectó entre 125 empresas, 85 mexicanas y 40 costarricenses. Para probar la hipótesis planteada, se usó el análisis ANOVA (análisis de varianza. Los resultados indican que hay diferencias entre algunas tecnologías y barreras de implementación de AMT entre ambos países.

  9. SQUID position sensor development

    1996-11-01

    I describe the development of an inductance position sensor for the STEP (satellite test of the equivalence principle) accelerometer. I have measured the inductance (with an experimental error of 0.5%) of a single-turn thin-film niobium pick-up coil as a function of the distance from a thin-film niobium disc (both at 4.2 K and superconducting). The circular pick-up coil had a diameter of 4 cm with a track width of 0264-9381/13/11A/022/img1. The disc (mock test mass) had a diameter of 4 cm. The distance range between the coil and disc was set by the range of a low-temperature differential capacitance sensor: 0 - 2 mm with a resolution of 0264-9381/13/11A/022/img2. The full range of the low-temperature translation stage was 0 - 4 mm. The inductance was measured using an LCR meter in a four-wire configuration. The measured inductance was compared to the inductance of a circular loop above a superconducting plane. Due to the fact that the thin-film disc is of finite size, the calculation differed from experiment by as much as 12%. I have also calculated the inductance by segmenting the thin-film niobium disc into 500 concentric rings (each with a width of 0264-9381/13/11A/022/img3). A discrepancy between calculation and experiment of approximately 3% was found.

  10. Gathering positive experience

    CERN Document Server

    2009-01-01

    Last Monday, the new CERN Machine Advisory Committee (CMAC) met for the first time, and we had good news to tell its members. Over the weekend, injection tests for both LHC beams were successfully carried out. In other words, we’ve had beam in the LHC for the first time since September 2008. That’s a good feeling, but it’s no reason for complacency. There’s still a long way to go before first physics at the new energy frontier. As the Bulletin has reported over recent weeks, we’re gathering a lot of positive experience with the new quench detection and protection system (QPS), which is already allowing us to monitor the LHC far better than we were able to in the past. So far, the QPS for three of the LHC’s eight sectors has been put through its paces, and we’ve also power tested those sectors to 2000 amperes, the equivalent of around 1.2 TeV per beam. The next step is to slowly increase the current to 4000 amperes, and...

    Full Text Available En varios países latinoamericanos, en las últimas tres décadas, se han creado un número significativo de universidades y otras instituciones de educación superior (IES que según los casos se denominan indígenas y/o interculturales. Adicionalmente, han surgido licenciaturas, diplomados y diversos tipos de programas especiales orientados a la inclusión de personas indígenas en universidades y otras IES “convencionales” (aquellas que no han sido creadas para responder a necesidades, demandas o propuestas de comunidades de pueblos indígenas o afrodescendientes.. Algunas de estas modalidades educativas han sido impulsadas por organizaciones y/o dirigentes indígenas, otras por universidades y otras IES “convencionales”, otras mediante alianzas entre estos tipos de instituciones y organizaciones indígenas, y otras por iniciativas de los Estados. En Argentina estos procesos son relativamente más recientes que en varios otros países de la región. Este artículo presenta un panorama de los tipos de experiencias que vienen desarrollándose en varios países latinoamericanos, señala sus principales logros y desafíos, y propone algunos aprendizajes potencialmente útiles para las experiencias que vienen desarrollándose en Argentina.

    International Nuclear Information System (INIS)

    2002-11-01

    The Canadian Association of Petroleum Producers (CAPP) is a firm believer in the need to take action to mitigate the risks associated with climate change, and that clear government policy is called for. The principles of sustainable development must guide this policy development effort. The initiatives required to address greenhouse gas emissions over both the short and long term must be carefully considered, and it is up to industries to ensure their production efficiency and emission intensity. Promoting improved performance of industries in Canada and developing technology that can be deployed internationally for larger global effects represents Canada's best contribution to progress on greenhouse gas emissions. The increase in energy demand along with increases in population and economic growth have contributed to an increase in greenhouse gas emissions despite improved energy efficiency in industry. Significant damage to the economy will result if Canada is to meet its commitment under the Kyoto Protocol, forcing the country to buy large quantities of foreign credits instead of using those funds for increased research and development. CAPP indicated that an effective plan must be: balanced, equitable, responsible, competitive, focused on technology and innovation, and based on agreements on sectoral plans. Each of these principles were discussed, followed by the fundamentals of approach for upstream oil and gas. The framework for climate change policy was described as well as the elements of a sector plan. CAPP wants to work with all levels of government on an appropriate plan for Canada, that considers our unique circumstances. Canada can play a significant role on the international stage by properly implementing the policy position proposed by the CAPP without unnecessary risks to the economy. refs

    Information and Communication Technologies (ICTs) have become increasingly present in our lives, and their use has spread considerably. This paper presents a review of the way ICTs can help practitioners and researchers to study, promote, and train positive emotions. It is framed within the field of Positive Technologies: the applied scientific approach to the study of the use of technology to improve the quality of personal experience, with the goal of increasing wellbeing. First, the article presents an introduction to the topic of technologies and positive emotions. Then, it describes how ICTs can aid in monitoring, assessing, promoting, modifying, and training positive emotions. Finally, implications and future directions of the role of Positive Technologies in positive emotions are discussed. The authors conclude that, in the near future, Positive Technologies and the field of positive emotions will interact synergistically, producing an exponential growth in the understanding and promotion of positive emotions.

    Full Text Available Background The relation of positive orientation (a basic predisposition to think positively of oneself, one’s life and one’s future and personality traits is still disputable. The purpose of the described research was to verify the hypothesis that positive orientation has predictive efficiency beyond the five-factor model. Participants and procedure One hundred and thirty participants (at the mean age M = 24.84 completed the following questionnaires: the Self-Esteem Scale (SES, the Satisfaction with Life Scale (SWLS, the Life Orientation Test-Revised (LOT-R, the Positivity Scale (P-SCALE, the NEO Five Factor Inventory (NEO-FFI, the Self-Concept Clarity Scale (SCC, the Generalized Self-Efficacy Scale (GSES and the Life Engagement Test (LET. Results The introduction of positive orientation as an additional predictor in the second step of regression analyses led to better prediction of the following variables: purpose in life, self-concept clarity and generalized self-efficacy. This effect was the strongest for predicting purpose in life (i.e. 14% increment of the explained variance. Conclusions The results confirmed our hypothesis that positive orientation can be characterized by incremental validity – its inclusion in the regression model (in addition to the five main factors of personality increases the amount of explained variance. These findings may provide further evidence for the legitimacy of measuring positive orientation and personality traits separately.

    Full Text Available Además de ser uno de los componentes más importantes de las relaciones contractuales entre los agentes de los sistemas de salud, el sistema de pago a prestadores es relevante para algunos de los principales criterios de valoración de un sistema de salud, como la eficiencia y la calidad. En este artículo tratamos de proporcionar un marco analítico sencillo para comprender la naturaleza de los distintos sistemas de pago, que ilustramos con una revisión de las fórmulas de pago utilizadas en dos grupos de países: 10 de la Organización de Cooperación y Desarrollo Económico (OCDE y cuatro de América Latina cuyas experiencias consideramos representativas. Primero presentamos un modelo básico para caracterizar las diferentes formas de pago, basado en dos dimensiones: la unidad de pago y la distribución de riesgos financieros entre el que vende y el que compra. Cada sistema de pago tiene ventajas e inconvenientes que deben evaluarse en función de los objetivos que se pretenda alcanzar. En un extremo tenemos la remuneración fija, que representa el pago prospectivo más puro, sin ajustes, como el pago capitativo, en el que los prestadores soportan todo el riesgo financiero derivado de la variabilidad de costos. En el otro extremo se sitúa el pago retrospectivo o por acto, con el que el riesgo incurrido por los prestadores es nulo y es el financiador quien soporta todo el riesgo derivado de la variabilidad de costos. Como suele ocurrir, los extremos no parecen óptimos y la cuestión consiste en escoger un sistema de remuneración intermedio. Para ello, es necesario seleccionar, por una parte, la unidad de pago óptima según los objetivos del financiador y, por otra, una distribución de riesgos que atribuya al prestador los riesgos derivados del mayor o menor grado de eficiencia que consiga en la prestación de los servicios.

The maximum temperature for exposure of magnesium to moist air without any risk of corrosion is 350 deg. C. Indeed, the oxidation rate follows a linear law above 350 deg. C although it reaches a constant level and keeps on very low under 350 deg. C. However, as far as corrosion is concerned this temperature limit can be raised up to 500 deg. C if moist air is very slightly charged with fluorinated compounds. Under pressure of CO{sub 2}, these three materials oxidate much more slowly even if 500 deg. C is reached. The higher is the temperature, the higher is the constant level of the weight increase and the quicker is reached this one.

    Full Text Available Luego de los programas de ajustes radicales, las entidades internacionales y los gobiernos de los países latinoamericanos vienen adoptando políticas en defensa de los más pobres, bien sea para compensar el deterioro del nivel de vida que aquellos originaron o bien para evitar un mayor descontento social. Hoy se acepta la intervención del Estado para afrontar los problemas de la pobreza y las desigualdades sociales, aunque desde una óptica liberal, es decir, expulsando la política y dando prioridad al mercado como entidad reguladora de la sociedad. Así, las políticas en la defensa de los pobres adquiere un carácter de mera beneficencia o de red de seguridad para quienes son excluidos por el mercado, y se basan en dos principios: hay que ser pacientes y esperar hasta mañana. Sus fundamentos filosóficos se encuentran en Rawls y Hayek, quienes aunque difieren en algunas cuestiones comparte cuatro temas fundamentales: el papel determinante del mercado en la formación de la sociedad, la apología del fetichismo de la mercancía, las desigualdades creadoras y la exclusión social como fenómeno individual.Following the radical programs of economic adjustment, international agencies and governments in Latin America have been shaping their policies to protect the very poor, either by compensating for a deterioration in standards of living to which they themselves had contributed to, or simply to avoid further social unrest. Today, the idea that the government should intervene to resol ve problems of poverty and disparity is accepted; but it is accepted from a liberal
    standpoint, that is to say, expeling politics from the equation and giving the market free rein to regulate society. In this view, policy to protect the poor makes the State some kind of charitable organization, a safety-net for those shut out of the market.

    Decision makers often need assistance in understanding dynamic interactions and linkages among economic, environmental and social systems in coastal watersheds. They also need scientific input to better evaluate potential costs and benefits of alternative policy interventions. The US EPA is applying sustainability science to address these needs. Triple Value (3V) Scoping and Modeling projects bring a systems approach to understand complex environmental problems, incorporate local knowledge, and allow decision-makers to explore policy scenarios. This leads to better understanding of feedbacks and outcomes to both human and environmental systems.The Suffolk County, NY (eastern Long Island) 3V Case uses SES interconnections to explore possible policy options and scenarios for intervention to mitigate the effects of excess nitrogen (N) loading to ground, surface, and estuarine waters. Many of the environmental impacts of N pollution have adverse effects on social and economic well-being and productivity. Key are loss of enjoyment and recreational use of local beach environments and loss of income and revenues from tourism and local fisheries. Stakeholders generated this Problem Statement: Suffolk County is experiencing widespread degradation to groundwater and the coastal marine environment caused by excess nitrogen. How can local stakeholders and decision makers in Suffolk County arrest and reverse this degradation, restore conditions to support a healthy thriving ecosystem, strengthen the County's resilience to emerging and expected environmental threats from global climate change, support and promote economic growth, attract a vibrant and sustainable workforce, and maintain and enhance quality of life and affordability for all County residents? They then built a Causal Loop Diagram of indicators and relationships that reflect these issues and identified a set of alternative policy interventions to address them.

    Full Text Available As sucessivas crises financeiras dos países "emergentes", na segunda metade dos anos 90, despertaram o interesse dos economistas do mainstream, uma vez que os modelos de crises cambiais de primeira geração, desenvolvidos nos anos 80, revelaram-se insuficientes para a compreensão destes eventos. Nesse contexto, foram desenvolvidos novos modelos que incorporaram, como condicionantes destas crises, fatos estilizados, que têm caracterizado o sistema financeiro internacional contemporâneo, dentre os quais os ataques especulativos auto-realizáveis e o comportamento de manada dos investidores estrangeiros. Este artigo pretende apresentar as principais características desses novos modelos. Primeiramente, apresentam-se os modelos desenvolvidos após a crise mexicana, que seguiram a tradição dos modelos de segunda geração desenvolvidos após a crise do Sistema Monetário Europeu. Em seguida, são examinados os modelos que surgem após a crise asiática, denominados "modelos de terceira geração", nos quais a crise cambial está intrinsecamente associada a uma crise bancária. Seguem-se algumas considerações finais.In the 90s, the succession of financial crises in the so called "emergent countries", with characteristics that haven't been considered by the first-generation models of exchange crises developed in the 80s, was followed by the emergency of new models of exchange crisis. The purpose of this article is to present these models, which have introduced in their analytical framework new elements, how the self-fulfilling expectations and the volatility of the capital flows. Firstly, we analyze the models developed after the Mexican crise, which have followed the tradition of the second-generation models that emerged after the European monetary system crise. Secondly, we examine the models developed after the Asian crise, labeled "third generation models", in which the exchange crise is intrinsically linked with a banking crise. We end up

    Full Text Available Cette étude se propose de dégager les caractéristiques du chantier de construction, dans son organisation et dans ses enjeux, en se référant aux évolutions architecturales perceptibles dans le diocèse de Clermont entre la fin du xie siècle et le xiiiesiècle. Le chantier ecclésiastique focalise les préoccupations, depuis les grands chantiers de la Limagne et les édifices d’ampleur, jusqu’aux sanctuaires plus modestes de plaine et de moyenne montagne. La réflexion prend aussi en compte le chantier laïc, ce dernier permettant d’éclairer la diversité des techniques, la position des différents acteurs, et de mesurer l’impact des savoir-faire et des environnements sur la condition sociale des bâtisseurs. D’autres pistes de réflexion connexes viennent aussi jalonner le propos pour élargir le débat en envisageant les niveaux de hiérarchisation et d’appropriation de l’espace bâti, la question de la matérialisation des héritages, ou encore la question de l’individualité de l’ouvrier qualifié.This study proposes to establish the characteristics of building construction, its organization and its consequences, while referring to the perceptible architectural evolutions in the diocese of Clermont from the end of 11th throughout the 13th century. The ecclesiastical building site focuses these concerns, from the large building sites of Limagne and its vast structures to the more modest sanctuaries of smaller mountains. The analysis is also interested in secular construction, as it allows us to clarify the diversity of techniques and the position of various actors, and to measure the impact of technical knowledge and the environment on the social conditions of the builders. We will also widen the debate by considering the following questions: how a constructed space is structured and appropriated; the affirmation of heritages; and the individuality of the skilled worker.Questo studio si propone di stabilire le

    The ToyBox-study developed an evidence- and theory-based intervention to improve preschoolers' energy balance-related behaviours - including physical activity (PA) - by targeting the kindergarten environment and involving their parents/caregivers. The present study aimed to examine the effect of the ToyBox-intervention on increasing Belgian preschoolers' objectively measured PA levels. A sample of 472 preschoolers (4.43 ± 0.55 years; 55.1% boys) from 27 kindergartens (15 intervention, 12 control kindergartens) in Flanders, Belgium were included in the data analyses. Preschoolers wore an ActiGraph accelerometer for six consecutive days and were included in the data analyses if they had a minimum of two weekdays and one weekend day, both at baseline and follow-up (one year later). Preschoolers' PA outcomes were estimated for an average day, weekday, weekend day, during school hours, and during after school hours. To assess intervention effects, multilevel repeated measures analyses were conducted for the total sample, and for sub-groups (according to sex, kindergarten levels of socio-economic status (SES) and risk groups (low levels of PA at baseline)) of preschoolers. Small intervention effects were found in the total sample. Most intervention effects were found in boys and in preschoolers from high SES kindergartens. Boys from the intervention group had an increase in vigorous PA (ß=1.47, p=0.03) and moderate-to-vigorous PA (ß=1.27, p=0.03) from baseline to follow-up, whereas PA levels in boys from the control group stagnated or decreased. In preschoolers from high SES kindergartens, the largest effects were found for PA outcomes during school hours and during after school hours. The results from the Belgian sample demonstrate that effects of the PA-component of the ToyBox-intervention on objectively measured PA were found in preschool boys and in preschoolers from high SES kindergartens, which means that the ToyBox-intervention was mainly effective in those sub

Diversos autores han hipotetizado la relación existente entre: salud oral y regímenes de bienestar. Geof Wood los clasifica basándose en: Índice de Desarrollo Humano, gasto público y flujo de divisas, en cinco categorías: 1. Régimen Social-demócrata, 2. Régimen Liberal, 3. Régimen Conservador, 4. Régimen de Seguridad Informal (A y B y 5. Régimen de Inseguridad (A y B. Propósito: Analizar la relación existente entre el tipo de régimen de bienestar y el índice de COP a los 12 años para 54 países en las últimas cinco décadas. Metodología: Estudio ecológico sobre fuentes secundarias de bases de datos de la OMS, Banco mundial, PubMed/Medline y sitios web de los países seleccionados. Resultados: El porcentaje de decrecimiento entre el primer y último COP reportado por cada país fue: Régimen Social-Demócrata (-86,6%, Régimen Conservador (-81,7%, Régimen Liberal (-79,0%, Régimen de Seguridad Informal A (-55,2%, Régimen de Seguridad Informal B (-46,9%, Régimen de Inseguridad A (-35,9%, Régimen de Inseguridad B (+136,8%. Conclusiones: El descenso de la caries observado en países desarrollados es resultado de medidas de salud pública, las condiciones-estilos de vida y la mejora de prácticas de autocuidado. Se espera que la incidencia de caries incremente en países africanos y asiáticos por el creciente consumo de azúcares e inadecuada exposición a fluoruros. Los retos futuros implican traducir conocimientos y experiencias en la promoción de la salud y prevención de la caries en los programas de acción.

    Full Text Available Moral imperialism is expressed in attempts to impose moral standards from one particular culture, geopolitical region or culture onto other cultures, regions or countries. Examples of Direct Moral Imperialism can be seen in various recurrent events involving multi-centric clinical trials promoted by developed (central countries in poor and developing (peripheral countries, particularly projects related to the theory of double standards in research. After the WMA General Assembly refused to change the Helsinki Declaration - which would have given moral recognition to the above mentioned theory - the USA abandoned the declaration and began to promote regional seminars in peripheral countries with the aim of "training" researchers on ethical perspectives that reflect America's best interests. Individuals who received such training became transmitters of these central countries' ideas across the peripheral countries, representing a form of Indirect Moral Imperialism. The paper proposes the establishment of regulatory and social control systems for clinical trials implemented in peripheral countries, through the formulation of ethical norms that reflect the specific contexts of these countries, along with the drawing up and validation of their own national norms.Imperialismo moral é a intenção de impor padrões morais de determinadas culturas, regiões geopolíticas e países a outras culturas, regiões ou países.

    The kinetics and mechanisms of the reaction of pure or low alloyed magnesium with various gas saturated by water vapor: oxygen, argon, nitrogen, air, carbon dioxide, have been studied and compared in the temperature range 350-600 deg C. After picturing the large chemical reactivity of magnesium surface, the more or less properties of the oxide film, always made of magnesia, have been shown depending on the nature of the gas carrying water vapor; in fact, metal sublimation occurs the more easily as the surrounding atmosphere is less oxidizing. Moreover, an activation energy change is systematic, but at a temperature which depends also on the latter. In the case of the alloys, the linear oxidation rate is generally obtained only after short induction periods, parabolic in nature. Two possibilities of corrosion inhibition of magnesium by water vapor are then demonstrated and explained: either by a partial superficial fluoridation, or when the carrier gas is carbon dioxide. Also, the extreme conditions of oxidation were studied, that is the ignition processes that occur at a particular temperature in every gas mixture. Finally, it is tried to evolve the fundamental and practical significance of all the results.

    This work is concerned with the study of acid-base reactions and of complex formation in ethanolamine and its mixtures with water. The ionic product of the solvent has been determined by an electro-chemical study of the H{sup +}/H{sub 2} system. The reduction curves for ethanolamine-water mixtures, for different acidities, have made it possible to follow the variations in the size of the pH domain as a function of the composition of the solvent. The form of this variation has been explained on the basis of the dielectric constant and the solvation of the proton by the ethanolamine. In the second part, the electrochemical systems of mercury have been studied by anodic polarography. In order to establish a parallel between the acid-base reactions and complex formation reactions, we have studied the stability of Hg (CN){sub 2} in water-ethanolamine mixtures. It has been possible to deduce the law for the variation of pK{sub c} with solvent composition. The representative graph of this function passes through a minimum for a proportion of about 50 per cent of ethanolamine as in the case of acids. This variation has been explained by the predominating influence of {epsilon} for ethanolamine propositions of over 50 per cent and by that of the solvation of Hg{sup 2+} for proportions of under 50 per cent. (author) [French] Ce travail porte sur l'etude des reactions acides-bases et de formation de complexes dans l'ethanolamine et ses melanges avec l'eau.

    To examine intraobserver, interobserver and between-day reproducibility of positional MRI for evaluation of navicular bone height (NVH) and medial navicular position (MNP). Positional MRI (pMRI) of the foot was performed on ten healthy participants (0.25 T G-scanner). Scanning was performed in supine and standing position, respectively. Two radiologists evaluated the images in a blinded manner. Reliability and agreement were assessed by calculation of intraclass correlation coefficient (ICC) and 95 % limits of agreement as a percentage of the mean (LOA%). Intraobserver and interobserver reliability was ''substantial'' in both supine and standing position (ICC 0.86-0.98) and showed good agreement (LOA% 4.9-14.7 %). Between-day reliability of navicular height and medial navicular position in standing position remained substantial (ICC 0.85-0.92) with adequate agreement (LOA% 8.3-19.8 %). In supine position between-day reliability was ''moderate'' for NVH (ICC 0.72) and ''slight'' for MNP (ICC 0.39). Agreement remained adequate between-days for MNP in supine position (LOA% 17.7 %), but it was less than adequate for NVH in supine position (LOA% 24.2 %). Navicular height and medial navicular position can be measured by pMRI in a very reproducible manner within and between observers. Increased measurement variation is observed between-days in supine position, which may be due to small positional differences or other unknown biomechanical factors. (orig.)

    A simple and cheap method is described for the manufacturing of individual positioning aids made of foamed polyurethane. Some examples are given to demonstrate the applicability of these positioning aids for the irradiation of different body regions. The reproducibility of the radiation field in the head and neck area was investigated with and without positioning aid. It was proved that the field is adjusted more exactly when positioning aids are applied. The dosimetric investigations performed showed a negligible influence of foamed polyurethane on the radiation quality. So the positioning aids could be left within the radiation field when drawing the field borders. (orig.) [de

Em crianças, a maior associação encontrada foi entre violência doméstica e problemas de externalização (OR = 9,5; IC 95% = 3,4-26,2, e entre ideação suicida e abuso sexual (OR = 8,3; p OBJECTIVE: To study the epidemiological evidence on the prevalence of exposure to violence and its relationship with mental health problems in low and middle-income countries. METHOD: The search was based on cross-sectional and cohort studies available in electronic databases (Medline, Psycinfo, Embase, SciELO and Lilacs, through July 2009, using the key words: "violence" and "mental disorders". RESULTS: The frequency of exposure to violence was shown to be very high and was significantly associated with mental health problems. Among children, the highest correlation was found to be of domestic violence with externalizing problems (OR = 9.5; 95% CI = 3.4-26.2, and suicidal ideation with sexual abuse (OR = 8.3; p < 0.05; among women, depression/anxiety symptoms correlated with intimate-partner psychological (OR = 3.2; 95% CI = 1.8-5.8 and sexual (OR = 9.7; 95% CI = 1.9-51.2 violence. In the general population, the highest prevalence rates of post-traumatic stress disorder were associated with sexual and domestic violence, kidnapping, and cumulative trauma exposure. Violence also correlated with common mental disorders. CONCLUSION: A

    Exercise tests with sublingual nitroglycerin were performed on 7 patients with true positive and 8 patients with false positive exercise test results. Four of 7 patients with true positive changes and 8 patients with false positive changes underwent exercise cardiac scintigraphy. Scintigrams showed perfusion defects in 4 patients with true positive outcomes, and no perfusion defect in 8 patients with false positive outcomes. Exercise tests with sublingual nitroglycerin were performed with the same load as that without nitroglycerin. In all 7 patients with true positive exercise test results, ST segment depression observed in the control exercise test was not observed in the nitroglycerin exercise test. In the false positive patients, ST segment depression observed in the control exercise test remained unchanged in 7 of 8 patients receiving nitroglycerin. Exercise tests with sublingual nitroglycerin as well as exercise cardiac scintigraphy are valuable tods in differentiating false positive from true positive patients. Furthermore, these data suggest that ST segment depression in the false positive patients may not be related to myocardial ischemia. (author)

Se procesó información sobre migración interna de censos latinoamericanos de la década del 2000, proveniente de la página WEB del Centro Latinoamericano y Caribeño de Demografía (CELADE. Asimismo se presenta información relativa al envejecimiento de Cuba y los restantes países y se han calculado otros indicadores como porcentaje de migrantes y no migrantes, y también se estima un conjunto de indicadores expresivos de cierta propensión a migrar entre las DAM en los últimos 5 años previos al censo para la población de 60 y más años de edad. Se han empleado técnicas propias de la estadística, como tablas de contingencias, así como métodos de análisis estadístico de correspondencias simples y múltiples para explorar las relaciones existentes entre las categorías de las diferentes características demográficas de los migrantes en países seleccionados. Uno de los resultados muestra que en Cuba y el resto de la región aún no se observan signos de migración interna asociada a la salida de la actividad laboral, lo cual sucede a partir de los 60 años de edad en países desarrollados. Los análisis de correspondencia múltiple, permitieron conocer grupos afines de categorías de las variables estudiadas cuando estas se analizan simultáneamente. Así se encontró similitud entre Cuba y Chile por el valor de las variables de población con 60 años y más, esperanza de vida al nacer, tasa global de fecundidad e índice de envejecimiento. Las proporciones más elevadas de migrantes de “toda la vida” se observen en aquellos países que registran un mayor nivel relativo de desarrollo económico y social; Cuba, Argentina y en menor medida Chile, muestran los más altos

  15. Are positive emotions just as "positive" across cultures?

    2011-08-01

    Whereas positive emotions and feeling unequivocally good may be at the heart of well-being among Westerners, positive emotions often carry negative associations within many Asian cultures. Based on a review of East-West cultural differences in dialectical emotions, or co-occurring positive and negative feelings, we predicted culture to influence the association between positive emotions and depression, but not the association between negative emotions and depression. As predicted, in a survey of over 600 European-, immigrant Asian-, and Asian American college students, positive emotions were associated with depression symptoms among European Americans and Asian Americans, but not immigrant Asians. Negative emotions were associated with depression symptoms among all three groups. We also found initial evidence that acculturation (i.e., nativity) may influence the role of positive emotions in depression: Asian Americans fell "in between" the two other groups. These findings suggest the importance of studying the role of culture in positive emotions and in positive psychology. The use of interventions based on promoting positive emotions in clinical psychology among Asian clients is briefly discussed. 2011 APA, all rights reserved

    Full Text Available Resumo Objetivou-se nesta revisão sistemática comparar as escalas de insegurança alimentar validadas e utilizadas nos países latino-americanos e caribenhos, e analisar os métodos empregados nos estudos de validação. Realizou-se busca nas bases eletrônicas Lilacs, SciELO e Medline. As publicações foram pré-selecionas pelos títulos e resumos, e posteriormente pela leitura integral. Dos 16.325 estudos revisados, selecionou-se 14. Foram identificadas 12 escalas validadas para os seguintes países: Venezuela, Brasil, Colômbia, Bolívia, Equador, Costa Rica, México, Haiti, República Dominicana, Argentina e Guatemala. Além dessas, tem-se a escala latino-americana e caribenha cuja abrangência é regional. As escalas variaram em relação ao padrão de referência utilizado, número de questões e diagnóstico da insegurança. Os métodos empregados pelos estudos para validação interna foi o cálculo do coeficiente alfa de Cronbach e o modelo Rasch; para validação externa os autores calcularam associação e/ou correlação com variáveis socioeconômicas e de consumo alimentar. A exitosa experiência da América Latina e Caribe no desenvolvimento de escalas nacionais e regionais pode ser exemplo para outros países que ainda não possuem esse importante indicador capaz de dimensionar o fenômeno da insegurança alimentar.

    In recent years, the use of MRI in patients with Crohn’s disease (CD) has increased. However, few data are available on how MRI parameters of active disease change during treatment with anti-TNF and whether these changes correspond to symptoms, serum biomarkers, or endoscopic appearance. The aim of this study was to determine the changes over time in MRI parameters during treatment with anti-TNF in patients with CD, and to verify the correlation between MRI score, endoscopic appearance and clinical-biological markers. We performed a prospective single centre study of 27 patients with active CD (18 males and 9 females; median age of 27,4 ys; age range, 19–49). All patients underwent ileocolonoscopy and MRI at baseline and 26 weeks after anti-TNF therapy. Endoscopic severity was graded according to the Simple Endoscopic Score for Crohn’s Disease (SES-CD) and Magnetic Resonance Index of Activity (MaRIA) was calculated. Patients underwent clinical evaluation (CDAI) and the C-reactive protein (CRP) level was measured. The associations between variables were assessed with Pearson’s bivariate correlation analysis. A total of 135 intestinal segments were studied. The median patient age was 27,4 years, 67 % were male and the mean disease duration was 6,1 years. For induction of remission, 18 patients were treated with infliximab and 9 with adalimumab. The mean SES-CD and MaRIA scores significantly changed at week 26 (SES-CD: 14,7 ± 8,9 at baseline vs. 4,4 ± 4,6 at 26 weeks - p < 0.001; MaRIA: 41,1 ± 14,8 at baseline vs. 32,8 ± 11,7 at 26 weeks - p < 0.001). Also the CDAI and serum levels of CRP decreased significantly following treatment (p < 0.001). The overall MaRIA correlated with endoscopic score and with clinical activity (CDAI) both at baseline and at week 26 (p < 0.05). The correlation between overall MaRIA and CRP was significant only at week 26 (p < 0.001). The MaRIA has a good correlation with SES-CD, a high accuracy for prediction of endoscopic

    Full Text Available La intención de este trabajo es explorar la relación entre ciudades (áreas urbanas y crecimiento económico nacional, con especial énfasis en el desarrollo del papel de las áreas urbanas en la nueva economía de la información, y lo que esto puede significar para la gestión urbana de los países en desarrollo. ¿Por qué la relación entre ciudades y crecimiento económico debiera ser de interés? Simplemente porque, como intentaremos demostrarlo, la forma en la cual las ciudades están estructuradas, gobernadas y administradas, puede tener un profundo impacto en los niveles de bienestar económico, y por lo tanto en la reducción de la pobreza. Creemos que el papel de las ciudades, y por lo tanto el de la administración urbana, crecerá y se volverá cada vez más importante a medida que los países adopten economías cada vez más basadas en la información. La nueva economía de la información plantea nuevas demandas a la planificación y gestión urbana. La tarea tanto para gestores como para planificadores urbanos en los países en desarrollo, no será fácil en absoluto. Mucho puede aprenderse de los errores cometidos en ciudades del norte, pero en países en desarrollo estos errores no necesitan repetirseThis paper explores the relationship between cities (urban areas and national economic growth, with special emphasis on the evolving role of urban areas in the new information economy and what this might mean for urban management in developing nations. Why should the relationship between cities and economic growth be of concern? Simply because, as we shall attempt to demonstrate, the manner in which cities are structured, governed and managed can have a profound impact on levels of economic welfare, and thus on poverty reduction. We argue that the role of cities and thus also of urban management will grow more vital as nations move to increasingly globalized and information-based economies.

    Exercise may have both a preventive and a therapeutic impact on mental health problems. The Exercise without Worries intervention aims to reduce stress and depressive symptoms in low-SES women by means of a group-based program combining physical exercise and psycho-education. Between September 2005 and May 2008, 161 Dutch low-SES women with elevated stress or depressive symptom levels were randomly assigned to the combined exercise/psycho-education intervention (EP), exercise only (E) or a waiting list control condition (WLC). The E condition provided low to moderate intensity stretching, strength, flexibility, and body focused training as well as relaxation, while the EP program integrated the exercise with cognitive-behavioral techniques. Depressive symptoms (CES-D) and perceived stress (PSS) were measured before and immediately after the intervention and at 2, 6 and 12 month follow-up. Multilevel linear mixed-effects models revealed no differential patterns in reduction of CES-D or PSS scores between the EP, E and WLC groups on the short (post-test and 2 month follow-up) or long term (6 and 12 months follow-up). Depressive symptom outcomes were moderated by initial depressive symptom scores: women from the EP and E groups with fewer initial symptoms benefited from participation on the short term. Further, women in the EP and E groups with the lowest educational level reported more stress reduction at post-test than women with higher educational levels. In the overall target population of low-SES women, no indications were found that the Exercise without Worries course reduced depressive symptom and stress levels on the short or long term. The findings do suggest, however, that exercise alone or in combination with psycho-education may be a viable prevention option for certain groups of disadvantaged women. Especially those low-SES women with less severe initial problems or those with low educational attainment should be targeted for future depression prevention

    In an attempt to investigate the impact of positive emotions on visual attention within the context of Fredrickson's (1998) broaden-and-build model, eye tracking was used in two studies to measure visual attentional preferences of college students (n=58, n=26) to emotional pictures. Half of each sample experienced induced positive mood immediately before viewing slides of three similarly-valenced images, in varying central-peripheral arrays. Attentional breadth was determined by measuring the percentage viewing time to peripheral images as well as by the number of visual saccades participants made per slide. Consistent with Fredrickson's theory, the first study showed that individuals induced into positive mood fixated more on peripheral stimuli than did control participants; however, this only held true for highly-valenced positive stimuli. Participants under induced positive mood also made more frequent saccades for slides of neutral and positive valence. A second study showed that these effects were not simply due to differences in emotional arousal between stimuli. Selective attentional broadening to positive stimuli may act both to facilitate later building of resources as well as to maintain current positive affective states.

    The present invention provides a control rod position control device which stores data such as of position signals and driving control rod instruction before and after occurrence of abnormality in control for the control rod position for controlling reactor power and utilized the data effectively for investigating the cause of abnormality. Namely, a plurality of individual control devices have an operation mismatching detection circuit for outputting signals when difference is caused between a driving instruction given to the control rod position control device and the control rod driving means and signals from a detection means for detecting an actual moving amount. A general control device collectively controls the individual control devices. In addition, there is also disposed a position storing circuit for storing position signals at least before and after the occurrence of the control rod operation mismatching. With such procedures, the cause of the abnormality can be determined based on the position signals before and after the occurrence of control rod mismatching operation stored in the position storing circuit. Accordingly, the abnormality cause can be determined to conduct restoration in an early stage. (I.S.)

    2014-01-01

    Full Text Available Positive psychology is a rapidly expanding subfield in psychology that has important implications for the field of second language acquisition (SLA. This paper introduces positive psychology to the study of language by describing its key tenets. The potential contributions of positive psychology are contextualized with reference to prior work, including the humanistic movement in language teaching, models of motivation, the concept of an affective filter, studies of the good language learner, and the concepts related to the self. There are reasons for both encouragement and caution as studies inspired by positive psychology are undertaken. Papers in this special issue of SSLLT cover a range of quantitative and qualitative methods with implications for theory, research, and teaching practice. The special issue serves as a springboard for future research in SLA under the umbrella of positive psychology.

    Full Text Available Positive interventions have been developed extensively in recent years and they have been tested and applied in very diverse settings. Despite the fact that most of the findings regarding their efficacy can be considered from positive to very positive, the possibility that, in some cases, positive interventions may have unexpected or even iatrogenic effects cannot be discarded. In this article, research from several sources is reviewed in order to inform decisions about what interventions might be inadequate for cases with specific characteristics or vulnerability traits. Finally, the importance of using positive interventions with caution and rigor even when working with individuals who do not have overt problems or psychological disorders is discussed.

    This book presents the proceedings of Positivity VII, held from 22-26 July 2013, in Leiden, the Netherlands. Positivity is the mathematical field concerned with ordered structures and their applications in the broadest sense of the word. A biyearly series of conferences is devoted to presenting the latest developments in this lively and growing discipline. The lectures at the conference covered a broad spectrum of topics, ranging from order-theoretic approaches to stochastic processes, positive solutions of evolution equations and positive operators on vector lattices, to order structures in the context of algebras of operators on Hilbert spaces. The contributions in the book reflect this variety and appeal to university researchers in functional analysis, operator theory, measure and integration theory and operator algebras. Positivity VII was also the Zaanen Centennial Conference to mark the 100th birth year of Adriaan Cornelis Zaanen, who held the chair of Analysis in Leiden for more than 25 years and was ...

    The first implementation of a position sensitive readout for a Micro Hole and Strip Plate (MHSP) is described and tested. The readout consists on a resistive layer crossing the anodes and connected to a preamplifier on each side. By weighing the charge pulses on both preamplifiers it is possible to determine the interaction point. A 100-200 {omega} resistance layer between consecutive strips was found to be the best compromise between position linearity and energy resolution. Preliminary results using 22.1 keV X-rays present a good linearity between the measured and the actual position with a mean deviation of about 0.15 mm and a position resolution of 1.6 mm full-width at half-maximum (FWHM), being limited by the analogue division electronic circuit. The performance of the MHSP position detector will be presented and discussed for 1D readout.

  9. Is the outcome of schizophrenia really better in developing countries? O prognóstico da esquizofrenia é realmente mais favorável nos países em desenvolvimento?

    Full Text Available That schizophrenia has a better prognosis in non-industrialized societies has become an axiom in international psychiatry; the evidence most often cited comes from three World Health Organization (WHO cross-national studies. Although a host of socio-cultural factors have been considered as contributing to variation in the course of schizophrenia in different settings, we have little evidence from low-income countries that clearly demonstrates the beneficial influence of these variables. In this article, we suggest that the finding of better outcomes in developing countries needs re-examination for five reasons: methodological limitations of the World Health Organization studies; the lack of evidence on the specific socio-cultural factors which apparently contribute to the better outcomes; increasing anecdotal evidence describing the abuse of basic human rights of people with schizophrenia in developing countries; new evidence from cohorts in developing countries depicting a much gloomier picture than originally believed; and, rapid social and economic changes are undermining family care systems for people with schizophrenia in developing countries. We argue that the study of the long-term course of this mental disorder in developing countries is a major research question and believe it is time to thoroughly and systematically explore cross-cultural variation in the course and outcome of schizophrenia.O fato de que a esquizofrenia possui um melhor prognóstico em sociedades não industrializadas tornou-se um axioma na psiquiatria internacional; as evidências mais comumente citadas provêm de três estudos trans-nacionais da Organização Mundial da Saúde (OMS.

  10. The present, past and future of the study of intellectual disability: challenges in developing countries Pasado, presente y futuro del estudio de la discapacidad intelectual: desafíos en los países en desarrollo

    Full Text Available There is strong evidence that socio-cultural factors largely determine what is seen as competent behaviour. Within western high income countries, driven by the values of utilitarian individualism, the construct of intellectual disability has been largely determined to meet the needs of urban, industrialised societies. In contrast, competence in non-industrialised societies may be more reflected in collaborative, interpersonal problem solving skills such as those found among Nigerian students labelled as intellectually disabled. However, people who are judged to be incompetent or "obtrusive" in countries deficient in support services, are often neglected and consigned to a life in poorly managed segregated institutions, as is the case in China, Russia and some countries in Eastern Europe. Non western countries that have a long history of a globalised economy, such as Taiwan and Japan also remain committed to segregated institutional provisions for people with an intellectual disability, despite a notional acceptance of inclusionary policies enunciated by the United Nations’ Declarations and Conventions. In this paper is concluded that it must be recognised that the population of people with an intellectual disability, regardless of how the condition is defined and classified, is quite heterogeneous. Their needs are also varied and not at all dissimilar to those of the general population. As developing countries adopt western style consumer-driven economies, there is an extreme danger that they, too, will follow the same trajectory of exclusion and impose the culture of "otherness" for a group whose contribution to that society will be devalued. Good science is futile unless it benefits all peoples.Existe amplia evidencia de que los factores socioculturales determinan en gran medida la percepción de conducta competitiva. En los países occidentales de altos ingresos, dominados por los valores del individualismo utilitario, las necesidades de

    Full Text Available Contínuas mudanças econômicas e culturais estão causando transformações no funcionamento das famílias e na educação das crianças pequenas em todas as camadas sociais. Essas transformações têm contribuído para o aumento da demanda e implementação de políticas de educação/cuidado infantil. Avanços políticos e legais têm ocorrido em vários países, nas últimas décadas. Esse processo configura-se sob formas diversas nos países desenvolvidos e nos em desenvolvimento. Naqueles e, em especial, nos países da Comunidade Européia, as justificativas para essas políticas fundamentam-se em um discurso pelos direitos da criança quanto ao acesso à educação e aos bens culturais, e pela igualdade de direitos e oportunidades de homens e mulheres. Já nos países em desenvolvimento, o discurso para ricos e pobres é bastante diferenciado, particularmente quando estabelece políticas para expansão do atendimento. Quando o alvo é a população pobre, negra e de zona rural, essas políticas se pautam por um discurso da necessidade de atender pobremente a pobreza, que transparece de maneira clara nos documentos do Banco Mundial. Neste artigo, propomo-nos a fazer uma reflexão crítica sobre as políticas para a infância nos países em desenvolvimento, tomando a América Latina como estudo de caso.Continuous economical and cultural changes are inducing various transformations in family functioning and young children education and care. Those changes generated an increased demand for early child education policies. During the last decades, various political and legal advances were observed in many countries.

In the European Community, more specifically, the discourse funding those policies emphasized both: children's rights to have access to education and cultural goods and the equality of rights and opportunities for men and women.

    A wafer positioning system was recently developed by Sandia National Laboratories for an Extreme Ultraviolet Lithography (EUVL) research tool. The system, which utilizes a magnetically levitated fine stage to provide ultra-precise positioning in all six degrees of freedom, incorporates technological improvements resulting from four years of prototype development experience. System enhancements, implemented on a second generation design for an ARPA National Center for Advanced Information Component Manufacturing (NCAICM) project, introduced active structural control for the levitated structure of the system. Magnetic levitation (maglev) is emerging as an important technology for wafer positioning systems in advanced lithography applications. The advantages of maglev stem from the absence of physical contact. The resulting lack of friction enables accurate, fast positioning. Maglev systems are mechanically simple, accomplishing full six degree-of-freedom suspension and control with a minimum of moving parts. Power-efficient designs, which reduce the possibility of thermal distortion of the platen, are achievable. Manufacturing throughput will be improved in future systems with the addition of active structural control of the positioning stages. This paper describes the design, implementation, and functional capability of the maglev fine positioning system. Specifics regarding performance design goals and test results are presented.

    Full Text Available At a campus in a low socioeconomic (SES area, our University allows enrolled nurses entry into the second year of a Bachelor of Nursing, but attrition is high.  Using the factors, described by Yorke and Thomas (2003 to have a positive impact on the attrition of low SES students, we developed strategies to prepare the enrolled nurses for the pharmacology and bioscience units of a nursing degree with the aim of reducing their attrition.  As a strategy, the introduction of review lectures of anatomy, physiology and microbiology, was associated with significantly reduced attrition rates. The subsequent introduction of a formative website activity of some basic concepts in bioscience and pharmacology, and a workshop addressing study skills and online resources, were associated with a further reduction in attrition rates of enrolled nursing students in a Bachelor of Nursing

    Over the last million years, human language has emerged and evolved as a fundamental instrument of social communication and semiotic representation. People use language in part to convey emotional information, leading to the central and contingent questions: (1) What is the emotional spectrum of natural language? and (2) Are natural languages neutrally, positively, or negatively biased? Here, we report that the human-perceived positivity of over 10,000 of the most frequently used English words exhibits a clear positive bias. More deeply, we characterize and quantify distributions of word positivity for four large and distinct corpora, demonstrating that their form is broadly invariant with respect to frequency of word use.

  20. Beam position optimisation for IMRT

    International Nuclear Information System (INIS)

    Holloway, L.; Hoban, P.

    2001-01-01

    Full text: The introduction of IMRT has not generally resulted in the use of optimised beam positions because to find the global solution of the problem a time consuming stochastic optimisation method must be used. Although a deterministic method may not achieve the global minimum it should achieve a superior dose distribution compared to no optimisation. This study aimed to develop and test such a method. The beam optimisation method developed relies on an iterative process to achieve the desired number of beams from a large initial number of beams. The number of beams is reduced in a 'weeding-out' process based on the total fluence which each beam delivers. The process is gradual, with only three beams removed each time (following a small number of iterations), ensuring that the reduction in beams does not dramatically affect the fluence maps of those remaining. A comparison was made between the dose distributions achieved when the beams positions were optimised in this fashion and when the beams positions were evenly distributed. The method has been shown to work quite effectively and efficiently. The Figure shows a comparison in dose distribution with optimised and non optimised beam positions for 5 beams. It can be clearly seen that there is an improvement in the dose distribution delivered to the tumour and a reduction in the dose to the critical structure with beam position optimisation. A method for beam position optimisation for use in IMRT optimisations has been developed. This method although not necessarily achieving the global minimum in beam position still achieves quite a dramatic improvement compared with no beam position optimisation and is very efficiently achieved.
