    Full Text Available La relación entre las variables de empowerment y compromiso organizacional ha sido un campo poco explorado desde la perspectiva organizacional. Esta investigación establece el nivel de influencia del empowerment queexperimentanloscolaboradores con respecto al compromiso hacia la organización para la cual laboran. Se utiliza como referencia un modelo generado con base en la descripción del empowerment en cuatro dimensiones: significado, competencia, autodeterminación e impacto; y del compromiso organizacional en tres: compromiso continuo, normativo y afectivo. Para validar el modelo propuesto, a partir de los resultados obtenidos en otros países, se administró una encuesta a 147 participantes de seis Pymes localizadas en el municipio de Celaya, Guanajuato, México. Las empresas pertenecen a los sectores de servicios, comercio y producción. Los resultados confirman las hipótesis planteadas en el sentido de que el empowerment es un predictor del compromiso organizacional; sin embargo, al analizar el impacto individual de cada una de las dimensiones se observa que sólo el compromiso afectivo tiene un impacto directo en las cuatro dimensiones planteadas.

    Full Text Available Background: Absenteeism caused by sick leaves generates an important economic burden. Aim: To determine if job satisfaction, psychological climate, hierarchic level and age are predictors of absenteeism caused by sick leaves. Material and Methods: FOCUS-93 survey that measures organizational culture and the satisfaction scale of Warr, Cook and Wall were distributed to 1387 workers of a hospital and answered by 874. Absenteeism data was obtained from the justified absenteeism registry of the Chilean Health Services. Results: Absenteeism is influenced by job satisfaction and organizational culture. Age has no influence. Hierarchic level has a negative influence on absenteeism among men and a negligible effect among women. Conclusions: Those workers that are not satisfied with their work have higher rates of absenteeism.

O objetivo do presente estudo foi explorar o conjunto de dimensões de personalidade como preditores dos CCO de ajuda e de voz. A amostra foi constituída por 335 empregados argentinos, que preencheram uma folha de dados sociodemográficos, o questionário de Personalidade de Eysenck e as escalas de CCO de ajuda e de voz desenvolvidas por Van Dyne e seus colaboradores. Análises de regressão stepwise indicaram que a tendência a extroversão constitui o melhor preditor dos CCO de voz, enquanto que os CCO de ajuda foram melhor explicados pela estabilidade emocional. Os resultados proporcionaram apoio parcial às relações hipotetizadas entre psicoticismo e CCO de voz, uma vez que as tendências não-psicóticas se revelaram bons preditores dos CCO de voz somente entre as mulheres. Os resultados dão base para elaboração de uma agenda para futuras investigações na área.Organizational Citizenship Behavior (OCB involves discretionary behavior, not required or formally rewarded, that has positive consequences for the organization. The main goal of this study was to examine the role of personality dimensions as predictors of employee's engagement in help and voice OCB. Sample was integrated by 335 Argentinean employees, which were asked to complete a battery of questionnaires including demographic items, Eysenck Personality Questionnaire and Help and Voice OCB scales developed by Van Dyne and his colleagues. Stepwise regression analysis revealed that extraversion was the best predictor of the voice behavior, and emotional stability was the best predictor when help behavior was the criterion. Results partially supported the hypothetical relationship between psicoticism and voice behavior, since non psychotic tendencies only emerged as predictors of voice among females

    Full Text Available Tecnologias disponíveis para a observação da Terra oferecem uma grande gama de informações sobre componentes ambientais que, por estarem relacionadas com a formação dos solos, podem ser usadas como variáveis preditoras no Mapeamento Digital de Solos (MDS. No entanto, modelos com um grande número de preditores, bem como a existência de multicolinearidade entre os dados, podem ser ineficazes no mapeamento de classes e propriedades do solo. O objetivo deste estudo foi empregar a Análise de Componentes Principais (ACP visando a selecionar e diminuir o número de preditores na regressão logística múltipla multinomial (RLMM utilizada no mapeamento de classes de solos. Nove covariáveis ambientais, ligadas ao fator de formação relevo, foram derivadas de um Modelo Digital de Elevação e denominadas variáveis originais, estas foram submetidas à ACP e transformadas em Componentes Principais (CP. As RLMM foram desenvolvidas utilizando-se atributos de terreno e as CP como variáveis explicativas. O mapa de solos gerado a partir de três CP (65,6% da variância original obteve um índice kappa de 37,3%, inferior aos 48,5% alcançado pelo mapa de solos gerado a partir de todas as nove variáveis originais.Available technologies for Earth observation offer a wide range of predictors relevant to Digital Soil Mapping (DSM. However, models with a large number of predictors, as well as, the existence of multicollinearity among the data, may be ineffective in the mapping of classes and soil properties. The aim of this study was to use the Principal Component Analysis (PCA to reduce the number of predictors in the multinomial logistic regression (MLR used in soil mapping. Nine environmental covariates, related to the relief factor of soil formation, were derived from a digital elevation model and named the original variables, which were submitted to PCA and transformed into principal components (PC. The MLR were developed using the terrain

Numa grande metanálise, apesar de limitações metodológicas, a frequência respiratória (FR foi considerada um preditor promissor. O objetivo deste estudo foi avaliar a FR como um preditor de falha de desmame da VM. MÉTODO: Avaliamos prospectivamente 166 pacientes destinados ao desmame da VM. A FR e outros parâmetros essenciais para desmame foram avaliados numa fase inicial de triagem. Os pacientes que apresentaram na triagem os parâmetros essenciais para desmame foram submetidos ao teste de respiração espontânea.

Para el análisis de los datos se utilizaron estadísticas descriptivas, el x2 de Pearson y un análisis multivariado de regresión logística. Resultados: El análisis con el x2 de Pearson arrojó diferencias significativas en ambas conductas: para los que habían tenido oportunidad de comprometerse en una relación sexual con penetración y la habían evitado (x2 [2]=45.378; p=0.000, así como entre quienes respondieron a una baja o una alta probabilidad de usar preservativo en el futuro (x2 [2]=235.622; p=0.000. El análisis de regresión logística reveló que la variable motivos predijo la conducta evitar una relación sexual con penetración (x22 [9]=33.805; p=0.000, mientras que también la variable motivos predijo la conducta intención de uso de preservativo en el futuro (x2 [8]=18.069; p=0.021.

    Abstract

    Customer satisfaction refers to the evaluation of results from the consumer experiences. A predictor of customer satisfaction could be the training of the contact employee. The aim of this paper is to analyze the predictive role that training can have on the value of the “service quality”-“customer satisfaction” relation. The sample of this study consists in 43 employees and 191 customers of hotels located in Veracruz State. The results show correlation between the level of employee training and quality of service perceived by the consumer and, consequently, their level of satisfaction.

CONCLUSIONES: En ambos sexos, el número de cigarros fumados con anterioridad predice la persistencia del tabaquismo. En las mujeres, el consumo inmoderado de alcohol también es un factor predictor. Cualquier medida preventiva del tabaquismo debe considerar de manera integral la prevención del consumo de alcohol.OBJECTIVE: To evaluate the predictive factors of smoking persistence in young students in Morelos, Mexico. MATERIAL AND METHODS: Information from a cohort study (1998-2001 of students in the public education system in the state of Morelos, Mexico was analyzed. The number of participants was 3 699. The analysis was carried out using logistic regression models. RESULTS: Of the 349 students who were active smokers according to the basal measurement, 192 persisted smoking in the second phase. Immoderate alcohol consumption by women, combined with the frequency of previous cigarrette consumption, was a predicting factor. In men, only the frequency of previous cigarette consumption predicted smoking persistence. CONCLUSIONS: For both genders, the number of cigarettes smoked previously was predictive of the persistence in tobacco consumption. In women, the immoderate use of alcohol

    étricos. OBJETIVO: Determinar el poder predictivo de indicadores antropométricos y establecer sus puntos de corte como discriminadores de presión arterial elevada. MÉTODOS: Estudio transversal realizado con una muestra de 660 adolescentes de 14 a 19 años siendo 51,9% jóvenes del sexo femenino. Se tuvieron en cuenta los siguientes indicadores antropométricos: índice de masa corporal (IMC, circunferencia de la cintura, razón cintura/estatura e índice de conicidad. La presión arterial elevada se caracterizó por valores superiores a un percentil 90 para presión arterial sistólica y/o presión arterial diastólica. Para identificación de los predictores de presión arterial elevada, se adoptó el análisis de las curvas Receiver Operating Characteristic (ROC, con intervalo de confianza del 95%. Posteriormente, se identificaron los puntos de corte con sus respectivas sensibilidades y especificidades. RESULTADOS: Las áreas bajo las curvas ROC con los intervalos de confianza fueron: Jóvenes del sexo masculino - circunferencia de cintura = 0,80 (0,72 - 0,89; IMC = 0,79 (0,68 - 0,89; razón cintura/estatura = 0,77 (0,66 - 0,88; índice de conicidad = 0,69 (0,56 - 0,81 y para las jóvenes del sexo femenino - circunferencia de la cintura = 0,96 (0,92 - 1,00; IMC = 0,95 (0,87 - 1,00; razón cintura/estatura = 0,93 (0,85 - 1,00; índice de conicidad = 0,74 (0,50 - 0,98. Se identificaron los diversos puntos de corte de los indicadores antropométricos con mejores poderes predictivos y sus respectivas sensibilidades y especificidades. CONCLUSIÓN: A pesar de la razón cintura/estatura y del IMC haber presentado buenas áreas bajo la curva ROC, se sugiere la utilización de la circunferencia de la cintura para la predicción de la presión arterial elevada.BACKGROUND: Hypertension is related to increased body fat, which can be evaluated by anthropometric indicators.

    Full Text Available Although seed weight is a key factor in understanding the reproductive biology of plant species, its value is unknown for a large proportion of the herbaceous species in the Mediterranean basin. This paper presents data on seed weight, dimensions and volume for 1 18 herbaceous species in acidic Mediterranean scrub and grassland in the centre of the Iberian Peninsula. This information is used to design predictive models of seed weight using multiple regression models. taking into account the phylogenetic effect. Five groups of models were designed: one using Trifolium species. three. using the families represented by the largest number of species (Catyophyllaceae, Asteraceae and Poaceae; and finally a general model using one species from each of the families present in the sample. The models are rated according to the absorbed variante, their significance in relation to the previous in complexity and the effort required to obtain the data for each one. We also test the validity of seed dimension data taken from literature sources to predict seed weight. The 1-0 seed dimensions are excellent weight predictors in the case of Trifolium (Weight = - 24.55 + 0.10D1 + 3.38D2, r2 = 0.94 and Asteraceae (Weight = - 20.90 + 1.19D1 + 1.67D2, r2 = 0.91 and are quite satisfactory in the case of the general model (Weight = - 16.01 +0.56D1 + 1.6002, r2 = 0.69.El peso de las semillas es un carácter clave para entender la biología reproductiva de las especies vegetales, pero se desconoce su valor para gran parte de las especies herbáceas de la cuenca mediterránea.

    with Bishop’s score for the prediction of vaginal delivery after labor induction, with 25 mcg of misoprostol. METHODS: a prospective study for the validation of a diagnostic test was conducted on 126 pregnant women with indication for labor induction. The patients were evaluated by Bishop’s score and transvaginal ultrasonography for cervical measurement. They also undergone obstetric transabdominal ultrasound to evaluate static and fetal weight, as well as the amniotic fluid index, and basal cardiotocography for the evaluation of fetal vitality. Labor was induced with vaginal and sublingual misoprostol, one of the tablets containing 25 mcg of the drug and the other only placebo. The tablets were administered every six hours, with a maximum number of eight. Frequency tables were obtained, and measures of central tendency and dispersion were calculated. ROC curves were constructed for the evaluation of Bishop’s score and ultrasonographic measurement of the uterine cervix for the prediction of vaginal delivery. RESULTS: the area under the ROC curve was 0.5 (p=0.8 for the ultrasonographic measurement of the uterine cervix, and 0.6 (p=0.02 for Bishop’s score (cut point ³4. Bishop’s score had a sensitivity of 56.2% and specificity of 67.9% for prediction of vaginal delivery, with a positive likelihood ratio of 1.75 and a negative one of 0.65. CONCLUSIONS: ultrasonographic measurement of the uterine cervix was not a good predictor of evolution to vaginal delivery among patients with misoprostol-induced labor. Bishop’s score was a better predictor of vaginal delivery under these circumstances.

Se utilizó una muestra de 580 deportistas con una edad media de 14.46 años. Se emplearon el Cuestionario del Clima Motivacional Percibido en el Deporte-2, la Escala de las Necesidades Psicológicas Básicas en el Ejercicio, el factor motivación intrínseca de la Escala de Motivación Deportiva y la Medida de la Intencionalidad para ser Físicamente Activo. Los resultados del modelo de ecuaciones estructurales mostraron que el clima motivacional que implica a la tarea predecía las tres necesidades psicológicas básicas y la intención de seguir siendo físicamente activo. Por otro lado, el clima motivacional que implica al ego predecía la necesidades de autonomía y de competencia, aunque con un peso de regresión en ambos casos mucho menor que como lo hacía el clima tarea. La satisfacción de las tres necesidades psicológicas básicas predijo positivamente la motivación intrínseca. Por su parte, la motivación intrínseca predijo la intención de ser físicamente activo en el futuro. Se discuten los resultados en relación a la importancia de fomentar un clima motivacional tarea en los practicantes para incrementar la adherencia a la práctica deportiva.AbstractThe study analyzed the prediction of perceived motivational climate, basic psychological needs satisfaction and intrinsic motivation on adherence to sports.

In the logistic regression analysis, only the ratio of "number of persons per room" remained as a malnutrition risk factor in the different geographical spaces analyzed. CONCLUSIONS: these results demonstrate situations that should be focused by the health sector to achieve a better understanding of the nutritional issue, as well as other citizenship related aspects.

Fifty-five players of the Under-14 category of Athletic Club Bilbao participated in this study. Players were classified into 4 playing positions: forwards (n=30, midfielders (n=15, defenders (n=37 and goalkeepers (n=15. Complete anthropometry, chronological age (CA, age at peak height velocity, 15-m sprint test, agility test, Yo-Yo IT level 1 (Yo-Yo IR1, counter-movement jump and hand dynamometry were measured. Results were transformed into z-scores and summed up to make two performance composites (SCORE and SCOREHG. One-way analysis of variance and a Bonferroni post-hoc test were used to examine the differences between playing positions. Multiple linear regression analysis was performed to estimate the contribution of independent variables to performance indicators. The level of significance was set at P<0.05. Significant differences were observed between playing positions in body mass and height (P<0.05; CA, maturity offset and muscle % (P<0.01; sum of skinfolds, fat %, endomorphy, sprint and agility tests (P<0.001. Stepwise regression analysis revealed that CA and sum of skinfolds were the most important predictors of performance. Collectively, playing positions were characterised by specific anthropometrical characteristics whereas no significant positional differences were observed in performance. This study provides further insight concerning coaches’ practice of selecting young soccer players because of anthropometrical characteristics rather than for performance advantages.

    Full Text Available Abstract Background To investigate and compare the predictors of personal and perceived stigma associated with depression. Method Three samples were surveyed to investigate the predictors: a national sample of 1,001 Australian adults; a local community sample of 5,572 residents of the Australian Capital Territory and Queanbeyan aged 18 to 50 years; and a psychologically distressed subset (n = 487 of the latter sample. Personal and Perceived Stigma were measured using the two subscales of the Depression Stigma Scale. Potential predictors included demographic variables (age, gender, education, country of birth, remoteness of residence, psychological distress, awareness of Australia's national depression initiative beyondblue, depression literacy and level of exposure to depression. Not all predictors were used for all samples. Results Personal stigma was consistently higher among men, those with less education and those born overseas. It was also associated with greater current psychological distress, lower prior contact with depression, not having heard of a national awareness raising initiative, and lower depression literacy. These findings differed from those for perceived stigma except for psychological distress which was associated with both higher personal and higher perceived stigma. Remoteness of residence was not associated with either type of stigma. Conclusion The findings highlight the importance of treating the concepts of personal and perceived stigma separately in designing measures of stigma, in interpreting the pattern of findings in studies of the predictors of stigma, and in designing, interpreting the impact of and disseminating interventions for stigma.

    2016-01-01

    Pharmacogenetics attempts to predict treatment response using a patient's "germline" genome as the biomarker of interest. This chapter on pharmacogenetic predictors of breast cancer response is divided into four sections. The first introduces readers to genetic variation and describes how variation in the germline genome can affect biology or pharmacology. The second section introduces the translational pathway for pharmacogenetic research and discusses the specific challenges to identifying pharmacogenetic predictors of breast cancer response. The third section is divided into three subsections, each of which discusses a distinct category of pharmacogenetic response predictors; pharmacokinetics, cancer cell sensitivity, and effector cell activation. Within each subsection a specific pharmacogenetic association is described in detail; CYP2D6-tamoxifen, BRCA-PARP inhibitors, and FCGRA-trastuzumab, respectively, followed by a general discussion of other less well-established examples or areas for further research. The chapter concludes with a summary of the current status of pharmacogenetic predictors of breast cancer response and a few predictions for the future of this field. PMID:26987536

    Full Text Available Giovanni Botero, en una célebre página de su Ragion di stato, se detuvo sobre el tema de la fuerza de la religión en los gobiernos. Esta función de la religión cristiana —para Botero, católica— es garante del orden público y se presenta también como opuesta a la generadora de desorden de Lutero y Calvino, quienes siembran por todo cizañas y revoluciones de estados y ruinas de los reinos. Estamos en los orígenes del esquema historiografía de la periodización de la Edad Moderna que confió precisamente a la Reforma el papel de nodriza de las revoluciones que nacieron en Europa.

  11. O ensaio como narrativa

    2016-02-01

    Full Text Available O artigo tenta demonstrar que todos os textos, mesmo aqueles cuja natureza é teórica, têm alguma forma de narrativa. Nem sempre são personagens que os ocupam, podem ser ideias, mas mesmo assim há um enredo conceitual que se passa. Modernamente, a forma dessa narrativa foi sobretudo o sistema, com a pretensão totalizadora presente, por exemplo, na filosofia de Hegel. Contemporaneamente, porém, a forma do ensaio – surgida ainda na era moderna – ganha destaque por sua forma descontínua de narrar. O objetivo do artigo é apontar que, se o ensaio é uma forma, como explicitaram Lukács, Benjamin e Adorno, ele é também uma forma de narrar – ainda que de narrar conceitualmente objetos da cultura.

    2008-12-01

    Full Text Available La presión social por constituir una forma indentitaria que sea acorde con el referente biológico es de origen histórico y se encuentra al servicio de prácticas de control y dominación social. Este artículo presenta una discusión sobre el lugar actual de la idea de identidad, especialmente en el plano de la sexualidad. Para esto recurre a la tesis de la filósofa Judith Butler, quien propone desde una visión deconstructivista y post-estructuralista una nueva definición de idenridad en términos de la iteración performativa. La identiclad es entendida entonces como una exigencia de inteligibiliclacl ante la sociedad, la cual limita las posibiliclades de expresión sexual.

    Full Text Available El artículo de Emmanuel Housset implica un esfuerzo de rehabilitación del concepto «persona» para la filosofía contemporánea y la fenomenología. Para ello el autor busca mostrar cómo poco a poco «persona» tomó otra significación que la de «personaje» o sujeto de derecho. Es en autores como san Agustín y santo Tomás de Aquino que se halla un acceso diferente que pone el énfasis más bien en su carácter relacional y responsivo de la persona, antes que en su dimensión autónoma y autotélica. Tal dimensión aparece, según Housset, junto con la idea de persona como creatura y en oposición a la de individuo racional dueño de sí. La dimensión afectiva, la personalidad despertada por las diversas figuras de la alteridad son algunas de las dimensiones de la persona que examina el autor a partir del examen de la carne, las pasiones, la memoria, la historicidad y el amor alteridad.Emmanuel Housset's paper is an effort to revitalize the concept of 'person' for contemporary philosophy and phenomenology To this end the author looks to show how little by little the understanding of 'person' took on a different meaning to that of 'character' or "right bearing individual". It is in authors such as St. Augustine and St. Thomas Aquinas that a different approach is found, one that puts emphasis on the relational and responsive character of a person, rather than on the autonomous and auto telic dimension. According to Housset, such a dimension appears together with the idea of the person as a creation, and in opposition to the idea of the rational individual, that is his own master. The emotional dimension and the personality that is awoken by the many figures of alterity are some of the dimensions of the person that the author analyzes, based on examining the flesh, passions, memory historicity and love.

    Full Text Available Durante los últimos años el crecimiento mundial de catástrofes naturales ha ido en franco aumento. Sin embargo, desde un enfoque sistémico puede verificarse que la gran mayoría de los desastres se origina en los países en desarrollo (entre ellos los latinoamericanos, siendo las pérdidas en ellos significativamente más altas que en los países industrializados. Bajo esta postura los desastres no son sólo naturales sino socio- naturales, enfatizando la estrecha relación de causalidad entre modelos de desarrollo y urbanización y procesos de generación de riesgos, al incrementar la vulnerabilidad de los sectores más desprotegidos. El desastre pone en evidencia así una situación (la pobreza y segregación urbana ya existente, pero no considerada hasta el momento de la catástrofe. Frente a este panorama el desastre aparece como oportunidad que precipita tres catalizadores de políticas habitacionales: tierra, asistencia técnica y financiamiento, incrementando la celeridad y la creatividad de las respuestas. El interrogante que surge es por qué esperar el desastre para ponerlos en marcha, cuando ninguno de ellos es estrictamente dependiente de la situación de riesgo, sino sujeto de luchas de poder.

    Full Text Available The aim of this article is to study the signs and symbols that appear in the hispanic medieval documents and manuscripts. These signs and symbols have usually been considered simply as mere elements to validate the charters. However, these alements were useful as a mean of visual communication between the high classes, able to generate charters, and the rest of medieval society—the majority illiterate— who received those charters. Because of their inability of understand an alphabetical code, they needed the graphic help to comprehend the message. Besides this, the article deals with non diplomatic signs and their function.

We have looked at Law from the viewpoint of society 's need to have basic mies for living together, with the juridical ruZe being one of the most important. We have highlighted the views of Hart and Kelsen on the foundations of the validity of Law. We have also considered the obligatoriness of Law; giving the point of view of tadbruch who, explaining his ''Theory of the Obligatoriness of Law ", concluded that the obligatoriness of Law can only be withdraw when there is a Clash between morals, law, use and social conventions. We have looked at the notion of the imperativeness of Law the central theme of the work -drawing on the views of Miguel Reale, for whom the juridical nonn cannot be reduced to a "command of a volitional nature", but rather the obligatory character of the juridical nonn arises from the pressure of social values. Del Vecchio, who is also quoted, recognized that imperativeness exists in the juridical norm, whether it is preceptive (a positive command or permissive. Also mentioned is the opinion of Tercio Sampaio Ferraz, for whom the juridical norm has imperativeness to the extent that the imposition of behaviour is unconditionally guaranteed.

Previous work on clinical predictors of psychopathology have identified the following: specific physical symptoms10-11; patient report of severity of illness11; recent stress12,13; low self-perception of health status13; and age less than 50.14 Two specific studies on the detection of psychopathology in the general medical population are worth highlighting. The first, by Jackson and his research team13 updating a 2001 study evaluating a prediction model with four parameters (recent stress, severity of physical symptoms, five or more specific symptoms, self-assessment of physical condition. They found that those patients who report recent stress, have five or more physical symptoms or a low self-perception of their health state are at a higher risk of having a psychiatric disorder. The second study, by Lowe et al. published in 2003,9 examines a series of factors that could serve as indicators of psychopathology in ambulatory medical (i.e. non-psychiatric patients. After evaluating several different models they found that the combination of four of factors (taken as a group had a high sensitivity (86%, specificity (100%, positive predictive value (100%, and negative predictive value (91%. This suggests that a physician could use the combination of these four indicators to evaluate for the presence of co morbid mental disorders. These factors are: self

  9. Distillation Column Flooding Predictor

    Energy Technology Data Exchange (ETDEWEB)

    George E. Dzyacky

    2010-11-23

    The Flooding Predictor™ is a patented advanced control technology proven in research at the Separations Research Program, University of Texas at Austin, to increase distillation column throughput by over 6%, while also increasing energy efficiency by 10%. The research was conducted under a U. S. Department of Energy Cooperative Agreement awarded to George Dzyacky of 2ndpoint, LLC. The Flooding Predictor™ works by detecting the incipient flood point and controlling the column closer to its actual hydraulic limit than historical practices have allowed. Further, the technology uses existing column instrumentation, meaning no additional refining infrastructure is required. Refiners often push distillation columns to maximize throughput, improve separation, or simply to achieve day-to-day optimization. Attempting to achieve such operating objectives is a tricky undertaking that can result in flooding. Operators and advanced control strategies alike rely on the conventional use of delta-pressure instrumentation to approximate the column’s approach to flood. But column delta-pressure is more an inference of the column’s approach to flood than it is an actual measurement of it. As a consequence, delta pressure limits are established conservatively in order to operate in a regime where the column is never expected to flood. As a result, there is much “left on the table” when operating in such a regime, i.e. the capacity difference between controlling the column to an upper delta-pressure limit and controlling it to the actual hydraulic limit. The Flooding Predictor™, an innovative pattern recognition technology, controls columns at their actual hydraulic limit, which research shows leads to a throughput increase of over 6%. Controlling closer to the hydraulic limit also permits operation in a sweet spot of increased energy-efficiency. In this region of increased column loading, the Flooding Predictor is able to exploit the benefits of higher liquid

    Building on a narrative synthesis of adoption theories by Wisdom et al. (2013), this review identifies 118 measures associated with the 27 adoption predictors in the synthesis. The distribution of measures is uneven across the predictors and predictors vary in modifiability. Multiple dimensions and definitions of predictors further complicate measurement efforts. For state policymakers and researchers, more effective and integrated measurement can advance the adoption of complex innovations such as evidence-based practices. PMID:24740175

    Full Text Available En este trabajo se pretende analizar la aportación que hacen la percepción del clima social, el comportamiento prosocial y la violencia escolar cotidiana sufrida y observada, informadas por parte del alumnado para predecir la adaptación socioemocional informada por profesores/as y padres o madres. Los participantes son 88 alumnos/as de 8-10 años de edad, de un colegio de la provincia de Málaga. Los resultados muestran que el alumnado evaluado presenta valores normalmente bajos en variables que indican inadaptación escolar y valores normativos en variables que se asocian a una buena adaptación escolar y social. Las correlaciones entre las variables predictoras y criterio muestran dos patrones diferentes: mientras que los datos de padres se asocian más activamente a las variables clima social y violencia sufrida en el caso de los profesores son prosocialidad y violencia sufrida. Los análisis de regresión demuestran también dos patrones diferentes para padres y para profesores, poniendo de manifiesto la importancia que tiene la violencia cotidiana sufrida en los resultados de adaptación o inadaptación escolar y social en alumnado que está en segundo ciclo de Educación Primaria, y la relevancia del comportamiento prosocial para predecir buenos resultados en el ámbito académico.

  2. El singular como diferencia divina

    2012-01-01

    Full Text Available Mucho se ha hablado sobre la posición de la diferencia como motor dialéctico de la existencia singular kierkegaardiana. El pecado, el otro o el Otro fisuran la subjetividad humana y la obligan a una identidad que guardará siempre la herida. El sujeto de la escisión es, en este sentido, el existente mismo, y tal debe ser el caso si la perspectiva se concentra en la individualidad. No obstante, y desde el punto de vista especulativo, creemos que los mismos principios utilizados por Kierkegaard para explicar el dinamismo de la existencia singular nos llevan más lejos, a saber, nos conducen al absoluto mismo como sujeto último de toda alteridad, respecto del cual el singular hace la diferencia.

    Full Text Available A punição de terroristas, em larga medida preliminar, ou os severos interrogatórios, não se adequam a um perfeito Estado de direito. Pertencem ao direito de exceção. Um Estado de direito que tudo abarque não poderia travar esta guerra, pois ele deveria tratar seus inimigos como pessoas e, conseqüentemente, não poderia tratá-las como fonte de perigo. Em Estados de direito que operam na prática de modo ótimo procede-se de outra maneira, e isso lhes dá a chance de não se quebrarem durante o ataque a seus inimigos.The preemptive punishment of terrorists and the use of harsh interrogation techniques are not within the classical standards of the Rule of Law. They belong rather to a state of exception. A State committed to all the usually accepted requirements of the Rule of Law would not be allowed to carry such a war, because it would have the duty to treat its enemies as persons. Therefore, it would not be authorized to treat them as a source of danger. Nevertheless, these classical standards have been challenged in the last two decades by major institutional changes that are now being discussed both in theoretical as in practical levels.

    Nurse burnout is a crucial issue for health care professionals and impacts nurse turnover and nursing shortages. Individual and situational factors are related to nurse burnout with predictors of burnout differing among cultures and health care systems. The predictors of nurse burnout in Asia, particularly Taiwan, are unknown. The purpose of this study was to investigate the predictors of burnout among a national sample of nurses in Taiwan. A secondary data analysis of a nationwide database investigated the predictors of burnout among 1,846 nurses in Taiwan. Hierarchical regression analysis determined the relationship between predictors and burnout. Predictors of Taiwanese nurse burnout were age, physical/psychological symptoms, job satisfaction, work engagement, and work environment. The most significant predictors were physical/psychological symptoms and work engagement. The variables explained 35, 39, and 18 % of the emotional exhaustion, personal accomplishment, and depersonalization variance for 54 % of the total variance of burnout. Individual characteristics and nurse self-awareness, especially work, engagement can impact Taiwanese nurses' burnout. Nurse burnout predictors provide administrators with information to develop strategies including education programs and support services to reduce nurse burnout. PMID:25536942

    2015-01-01

    The purpose of this study was to identify personality and individual difference measures related to driver vengeance, as measured by the Driver Vengeance Questionnaire (DVQ; Wiesenthal, Hennessy, & Gibson, 2000). There were 170 undergraduate students who completed paper-and-pencil questionnaires including the DVQ and measures of narcissism, impulsivity, and trait driver stress. A hierarchical linear regressidn predicting DVQ score revealed that being male (β = .25), narcissism (β = .19), and trait driver stress (β = .41) were significantly associated with vengeance. Impulsivity was significant in the third block of the regression but was not a significant predictor of vengeance in the final block. Interactions between gender and the individual difference measures were not significant. The final model accounted for 34% of the variance. Implications of the results and directions for future research are discussed. PMID:25774420

    Full Text Available La respuesta al tratamiento psicológico para el Trastorno Obsesivo-Compulsivo (TOC es variable, y las tasas de abandono y recaída son preocupantes. Mientras los estudios que analizan la reducción de los síntomas son favorables, los resultados son menos alentadores cuando estos se definen en términos de cambio clínicamente significativo. Existe poco conocimiento de lo que predice el resultado del tratamiento. Este estudio examinó predictores demográficos, sintomáticos y cognitivos de los resultados en 79 participantes en terapia cognitivo-conductual individualizada para el TOC. Después de investigar las diferencias entre los que completaron el tratamiento y no lo finalizaron, se analizó la respuesta al tratamiento según la definición de gravedad post-tratamiento de los síntomas y el cambio clínicamente fiable, así como predictores de la respuesta al tratamiento. Los que completaron el tratamiento eran menos propensos a presentar comorbilidad. Baja intensidad de síntomas en el pre-tratamiento y mayor perfeccionismo/intolerancia a la incertidumbre fueron los mejores predictores de los resultados. Los cambios en las creencias obsesivas se asociaron con el cambio sintomático, aunque sólo perfeccionismo/intolerancia a la incertidumbre fue predictor del cambio posttratamiento.

  19. Predictors of intractable childhood epilepsy

    International Nuclear Information System (INIS)

    To determine the prognosis of seizures in epileptic children and identify early predictors of intractable childhood epilepsy. All children (aged 1 month to 16 years) with idiopathic or cryptogenic epilepsy who were treated and followed at the centre during the study period were included. The patients who had marked seizures even after two years of adequate treatment were labeled as intractable epileptics (cases). Children who had no seizure for more than one year at last follow-up visit were the controls. Adequate treatment was described as using at least three anti-epileptic agents either alone or in combination with proper compliance and dosage. Records of these patients were reviewed to identify the variables that may be associated with seizure intractability. Of 442 epileptic children, 325 (74%) intractable and 117 (26%) control epileptics were included in the study. Male gender (OR=3.92), seizures onset in infancy >10 seizures before starting treatment (OR=3.76), myoclonic seizures (OR=1.37), neonatal seizures (OR=3.69), abnormal EEG (OR=7.28) and cryptogenic epilepsy (OR=9.69) and head trauma (OR=4.07) were the factors associated with intractable epilepsy. Seizure onset between 5-7 years of age, idiopathic epilepsy, and absence seizures were associated with favourable prognosis in childhood epilepsy. Intractable childhood epilepsy is expected if certain risk factors such as type, age of onset, gender and cause of epilepsy are found. Early referral of such patients to the specialized centres is recommended for prompt and optimal management. (author)

  11. Mechanical Predictors of Discomfort during Load Carriage.

    Directory of Open Access Journals (Sweden)

    Patrick D Wettenschwiler

    Full Text Available Discomfort during load carriage is a major issue for activities using backpacks (e.g. infantry maneuvers, children carrying school supplies, or outdoor sports. It is currently unclear which mechanical parameters are responsible for subjectively perceived discomfort. The aim of this study was to identify objectively measured mechanical predictors of discomfort during load carriage. We compared twelve different configurations of a typical load carriage system, a commercially available backpack with a hip belt. The pressure distribution under the hip belt and the shoulder strap, as well as the tensile force in the strap and the relative motion of the backpack were measured. Multiple linear regression analyses were conducted to investigate possible predictors of discomfort. The results demonstrate that static peak pressure, or alternatively, static strap force is a significant (p<0.001 predictor of discomfort during load carriage in the shoulder and hip region, accounting for 85% or more of the variation in discomfort. As an additional finding, we discovered that the regression coefficients of these predictors are significantly smaller for the hip than for the shoulder region. As static peak pressure is measured directly on the body, it is less dependent on the type of load carriage system than static strap force. Therefore, static peak pressure is well suited as a generally applicable, objective mechanical parameter for the optimization of load carriage system design. Alternatively, when limited to load carriage systems of the type backpack with hip belt, static strap force is the most valuable predictor of discomfort. The regionally differing regression coefficients of both predictors imply that the hip region is significantly more tolerant than the shoulder region. In order to minimize discomfort, users should be encouraged to shift load from the shoulders to the hip region wherever possible, at the same time likely decreasing the risk of low

  14. Multivariate Regression with Block-structured Predictors

    Science.gov (United States)

    Ye, Saier

    We study the problem of predicting multiple responses with a common set of predicting variables. Applying generalized Ordinary Least Squares (OLS) criterion on the responses altogether is practically equivalent to OLS estimation on the responses separately. Possible correlations between the response variables are overlooked. In order to take advantage of these interrelationships, Reduced-Rank Regression (RRR) imposes rank constraint on the coefficient matrix. RRR constructs latent factors from the original predicting variables, and the latent factors are the effective predictors. RRR reduces number of parameters to be estimated, and improves estimation efficiency. In the present work, we explore a novel regression model to incorporate "block-structured" predicting variables, where the predictors can be naturally partitioned into several groups or blocks. Variables in the same block share similar characteristics. It is reasonable to assume that in addition to an overall impact, predictors also have block-specific effects on the responses. Furthermore, we impose rank constraints on the coefficient matrices. In our framework, we construct two types of latent factors that drive the variation in the responses. We have joint factors, which are formed by all predictors across all blocks; and individual factors, which are formed by variables within individual blocks. The proposed method exceeds RRR in terms of prediction accuracy and ease of interpretation in the presence of block structure in the predicting variables.

    Full Text Available El objetivo de este trabajo es discutir la importancia de los estudios de arqueología terrestre y subacuática como parte de un mismo proceso de interpretación del pasado. Se entiende que el registro arqueológico puede hallarse actualmente en una variedad de ambientes tanto terrestres como subacuáticos a causa de varias razones, como por ejemplo las oscilaciones de los niveles de agua ocurridas entre el Pleistoceno Final y el Holoceno Medio. Por lo tanto, se propone que para su recuperación debe utilizarse una metodología adaptada al medio ambiente en el cual se encuentre. En este sentido, es importante la interpretación integral del paisaje para acceder a la comprensión de la diversidad ambiental en la que se puede emplazar un sitio arqueológico, y en consecuencia poder “bucear” un registro integrado.

    Full Text Available En el Centro Penitenciario de Hombres de Barcelona ha habido un aumento creciente de ingresos por delitos contra la seguridad vial. El objetivo de esta investigación es obtener un perfil psicológico en una muestra de 115 internos, analizar cuáles son los predictores en la conducción agresiva, y finalmente contrastar la posible existencia de diferentes tipologías, en función de la ausencia o presencia de otros delitos, con o sin componentes agresivos. Los resultados muestran que las causas o estados que causan irritación, los antecedentes familiares de conducción agresiva y la presencia de trastornos psiquiátricos son predictores de la conducta agresiva en la conducción, así como la agresividad física es también un predictor de los accidentes. No hay diferencias en internos que también presentan otras tipologías delictivas.

    Full Text Available El suelo es una unidad básica en el funcionamiento y dinámica de los agroecosistemas, ya que proporciona el sustento físico y biológico para la producción vegetal. Aunque el efecto de las prácticas antropógenas sobre el componente abiótico del suelo está ampliamente documentado, existen pocas herramientas capaces de medir el impacto de estas prácticas en la biodiversidad del ecosistema edáfico. Los nematodos del suelo constituyen un grupo de invertebrados de elevada importancia ecológica que presentan atributos que les convierte en valiosas herramientas como indicadores biológicos. Su extraordinaria diversidad taxonómica y funcional, su abundancia y ubiquidad, y la rápida respuesta de las comunidades de nematodos edáficos a perturbaciones ambientales, como el laboreo o la aplicación de insumos químicos, han convertido la nematofauna en un indicador clave en la evaluación del efecto del manejo agrario sobre los ecosistemas. La participación de los nematodos en múltiples eslabones funcionales dentro de la red trófica edáfica hace que sean también indicadores de numerosos procesos ecológicos y biológicos, como el mantenimiento del ciclo de nutrientes o el control de especies plaga.Este trabajo sintetiza los resultados obtenidos en la utilización de la nematofauna como indicadora de perturbaciones ambientales en los agroecosistemas, y expone una breve reseña del estado de la Nematología como disciplina científica en España.

  17. Praiseworthiness: predictors of positive interpersonal judgments.

    Science.gov (United States)

    Ogletree, Shirley M; Covington, Jennifer A; Archer, Richard L

    2013-06-01

    Deterministic attitudes, information about a person's background, one's perceived similarity to a target person, and attributions of effort and ability may affect praiseworthiness. Two vignette studies with college student participants were conducted to consider this issue. Based on regression analyses, attributing achievement to effort was the strongest predictor of praiseworthiness across both studies. In addition, evidence for an augmenting effect of an impoverished background on praiseworthiness was found. In the first study, perceived similarity to the target individual and religious-philosophical determinism were also predictors of praiseworthiness, while belief in free will predicted praiseworthiness in the second study. Judgments of praiseworthiness may be tied to a number of factors; among the most important of these are overcoming an impoverished childhood background and the attributed effort required for success.

The sample consisted of 406 students (aged 14-16 in the 8th to 11th grades of the Russian formal education system. Conscious self-regulation together with intelligence and cognitive abilities was determined to be a significant predictor of academic success. The Study 1 results revealed that the general level of self-regulation of learning activity and certain regulatory features were significant predictors of different types of mathematical achievements: academic grades, scores on exams, mathematical fluency, as well as solving logical mathematical problems and equations. The present study is the first to show the mediating role of self-regulation in relation to intelligence, cognitive features, and academic success. Study 2 found evidence that conscious self-regulation and intelligence can predict academic achievement in the humanities, mathematics, and natural sciences... At the same time, this determination has its peculiarities in particular variables of intelligence and certain self-regulation processes depending on the substantive characteristics of the academic subjects. Regression models of academic success in the humanities identified verbal intelligence associated with vocabulary as highly significant and a definitive requirement for success in these subjects. Study 1 and Study 2 showed that the only significant predictors of success in algebra and geometry were quantitative- relations intelligence and spatial intelligence. The implications of these findings for investigating predictors of academic achievement are discussed.

  16. Crowdsourcing novel childhood predictors of adult obesity.

    Directory of Open Access Journals (Sweden)

    Kirsten E Bevelander

    Full Text Available Effective and simple screening tools are needed to detect behaviors that are established early in life and have a significant influence on weight gain later in life. Crowdsourcing could be a novel and potentially useful tool to assess childhood predictors of adult obesity. This exploratory study examined whether crowdsourcing could generate well-documented predictors in obesity research and, moreover, whether new directions for future research could be uncovered. Participants were recruited through social media to a question-generation website, on which they answered questions and were able to pose new questions that they thought could predict obesity. During the two weeks of data collection, 532 participants (62% female; age  =  26.5±6.7; BMI  =  29.0±7.0 registered on the website and suggested a total of 56 unique questions. Nineteen of these questions correlated with body mass index (BMI and covered several themes identified by prior research, such as parenting styles and healthy lifestyle. More importantly, participants were able to identify potential determinants that were related to a lower BMI, but have not been the subject of extensive research, such as parents packing their children's lunch to school or talking to them about nutrition. The findings indicate that crowdsourcing can reproduce already existing hypotheses and also generate ideas that are less well documented. The crowdsourced predictors discovered in this study emphasize the importance of family interventions to fight obesity. The questions generated by participants also suggest new ways to express known predictors.

    Full Text Available INTRODUCCION: La proteína C reactiva (PCR es un examen simple y de bajo costo que según la literatura tiene buena asociación para la evaluación pronóstica en Pancreatitis Aguda (PA. OBJETIVO: Determinar valor pronóstico de PCR para severidad, presencia de complicaciones y mortalidad intrahospitalaria de PA. MATERIAL Y METODO: Estudio de cohorte retrospectiva de pacientes adultos ingresados al Hospital Dr. Gustavo Fricke, Viña del Mar durante el año 2007. Se identificaron características generales, etiología, score de Balthazar, PCR, complicaciones y mortalidad. Se utilizó test de Mann Whitney para comparación de medianas y curvas ROC. RESULTADOS: Se incluyeron 59 pacientes, siendo el 54,23% hombres. La mediana de edad fue 51 años. La etiología biliar se observó en 57,62%. La mediana de hospitalización fueron 12 días. El 40,67% presentó complicaciones, siendo más frecuente la necrosis pancreática (20,33%. El nivel de PCR mostró diferencias significativas entre pacientes con y sin gravedad imagenológica (33,5mg/dL vs 15,9mg/dL, p=0,0009, complicaciones intrahospitalarias (40mg/dL vs 15,9mg/dL, p<0,0001 y mortalidad intrahospitalaria (66mg/dL vs 22mg/dL, p=0,0061. El área bajo la curva ROC fue de 0,75; 0,84 y 0,91 respectivamente, todos estadísticamente significativos. La sensibilidad, especificidad, likelihood ratio (LR positivo, LR negativo para gravedad imagenológica con un punto de corte de 13,14mg/dL fue 88%, 54%, 1,83 y 0,28 respectivamente. Para predecir mortalidad con un valor de 32,76mg/dL, estos fueron 100%, 71%, 3,43 y 0 respectivamente. DISCUSION. Un valor de PCR de 40mg/dL es buen marcador pronóstico de complicaciones intrahospitalarias. Niveles aumentados tienen alta sensibilidad para predecir gravedad imagenológica y mortalidad intrahospitalaria.

  1. EL DERECHO COMO COMPLEJIDAD DE SABERES DIVERSOS

    2011-08-01

    Full Text Available El motivo principal de este trabajo consiste en observar la estrecha vinculación que existe entre los distintos grados del saber y la configuración misma del mundo jurídico como objeto cultural. Así pues, desde esta perspectiva, se advierte que el Derecho puede ser considerado un fenómeno complejo, en gran medida, debido a los distintos tipos de conocimiento que intervienen en su construcción. El saber, en este marco, será entendido como aquel conjunto de información referida a hechos o abstracciones, que se expresan en proposiciones lógicas y responden a algún criterio de verdad admitido como válido para el caso. Sin embargo, es preciso señalar también que esta definición genérica del conocimiento debe completarse con los conceptos propios de los distintos grados (o clases de saberes que fueron consolidándose históricamente, tales como la filosofía, la ciencia, la tecnología, el saber empírico o popular y el religioso[1]. Hasta donde entendemos, sobre cada uno de estos términos se ha ido desplegando una rica trama teórica. No obstante, en este artículo sólo expondré una breve caracterización de los mismos, con el propósito de señalar de manera aproximativa, por qué razón el Derecho puede ser comprendido como una complejidad, resultante de la interacción diversa de todos los tipos de conocimiento mencionados y no sólo, como el producto de la ciencia o la filosofía, en particular. Veamos, entonces en primer lugar, cuáles son los rasgos más destacados de los modelos gnoseológicos vigentes; para poder observar, en segundo término, los modos por los cuales todos ellos posibilitan la construcción del Derecho en la actualidad.

    Full Text Available La sintomatología depresiva es prevalente durante la adolescencia, pero no todos los adolescentes experimentan el mismo nivel y evolución de esta sintomatología, lo que sugiere la necesidad de identificar diferencias en las trayectorias de los síntomas. Usando Growth Mixture Modeling analizamos diferentes trayectorias de síntomas depresivos en 1.072 adolescentes chilenos (12-15 años, 54% mujeres, NSE diverso. Primero, se seleccionó un modelo basal y luego se utilizó la irritabilidad del adolescente, la calidez, demanda y falta de respeto de la madre como predictores de la pertenencia a las clases. Se seleccionó un modelo con cuatro clases latentes de síntomas depresivos: alta persistente (12%, baja estable (56%, decreciente (15% y creciente (17%. La clase baja estable fue la más prevalente y se caracterizó por alto nivel de calidez maternal y bajo nivel de falta de respeto materna e irritabilidad del adolescente, en tanto que la clase alta persistente presentó características opuestas (baja calidez y alta demanda materna e irritabilidad del adolescente. Se observaron diferencias en la prevalencia de clases por sexo. Estos resultados resaltan la importancia de identificar diferentes trayectorias de síntomas depresivos y sus predictores. La asociación entre las dimensiones parentales y las trayectorias de síntomas depresivos persistentes provee evidencia de que los comportamientos parentales pueden servir, tanto como factores protectores como de riesgo.

    The purposes of this study were to identify predictors of hope in the literature reviewed, to use meta-analysis to determine the mean effect size (ES) across studies between each predictor and hope, and to examine four moderators on each predictor-hope relationship. Using preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines for the literature reviewed, 77 published studies or doctoral dissertations completed between 1990 and 2012 met the inclusion criteria. Eleven predictors of hope were identified and each predictor in relation to hope was subjected to meta-analysis. Five predictors (positive affect, life satisfaction, optimism, self-esteem, and social support) of hope had large mean ESs, 1 predictor (depression) had a medium ES, 4 predictors (negative affect, stress, academic achievement, and violence) had small ESs, and 1 predictor (gender) had a trivial ES. Findings are interpreted for the 11 predictors in relation to hope. Limitations and conclusions are addressed; future studies are recommended. PMID:25421543

  9. Barrios cerrados como estrategia de desarrollo municipal

    Directory of Open Access Journals (Sweden)

    Nora Libertun de Duren

    2010-07-01

    Full Text Available Los barrios cerrados han sido generalmente estudiados desde la perspectiva de sus residentes, preferencias, estatus económico, y ambiciones sociales. Aun más, estos proyectos han sido asociados con el debilitamiento del estado y un desarrollo urbano gobernado por las necesidades del mercado. Sin embargo, queda por responder cual ha sido el papel de las instituciones públicas en la proliferación de barrios cerrados. Este artículo analiza el caso de Buenos Aires, donde las municipalidades suburbanas más pobres han visto a las urbanizaciones cerradas como una estrategia de desarrollo local. Aprovechando la descentralización de la reglamentación sobre los usos del suelo del nivel provincial al municipal, las municipalidades con un alto porcentaje de hogares pobres han facilitado el desarrollo de urbanizaciones cerradas como estrategia para aumentar el empleo local y la inversión privada en la zona. Como consecuencia de esta política, las urbanizaciones cerradas se han concentrado en las municipalidades más pobres del cono urbano bonaerense. Así, se ha incrementando la polarización social dentro de cada municipalidad, lo cual llama a revisar el efecto de las reformas de descentralización en la formación de una sociedad mas inclusiva y participativa.

  14. A simple predictor based on negative group delay

    CERN Document Server

    Voss, Henning U

    2016-01-01

    A very simple linear signal predictor that uses past predicted values rather than past signal values for prediction is presented. Therefore, man-made or natural systems utilizing this predictor would not require a memory of input signal values but only of already predicted, internalized states. This delay-induced negative group delay (DINGD) predictor affords real-time prediction of signals without the need for a specific signal model. Its properties are derived analytically and are numerically tested on broadband input data. As a further result this predictor is able to predict non-smooth signal patterns that cannot be expressed as envelopes of oscillatory signals.

    Objective To investigate time-dependent predictors of institutionalization in old age using a longitudinal approach. Methods In a representative survey of the German general population aged 75 years and older predictors of institutionalization were observed every 1.5 years over six waves. Conditional fixed-effects logistic regressions (with 201 individuals and 960 observations) were performed to estimate the effects of marital status, depression, dementia, and physical impairments (mobility, hearing and visual impairments) on the risk of admission to old-age home or nursing home. By exploiting the longitudinal data structure using panel econometric models, we were able to control for unobserved heterogeneity such as genetic predisposition and personality traits. Results The probability of institutionalization increased significantly with occurrence of widowhood, depression, dementia, as well as walking and hearing impairments. In particular, the occurrence of widowhood (OR = 78.3), dementia (OR = 154.1) and substantial mobility impairment (OR = 36.7) were strongly associated with institutionalization. Conclusion Findings underline the strong influence of loss of spouse as well as dementia on institutionalization. This is relevant as the number of old people (a) living alone and (b) suffering from dementia is expected to increase rapidly in the next decades. Consequently, it is supposed that the demand for institutionalization among the elderly will increase considerably. Practitioners as well as policy makers should be aware of these upcoming challenges. PMID:26658776

  15. Predictors of tonic immobility during traumatic events

    Arturo Bados

    2015-10-01

    Full Text Available Tonic immobility (TI is a possible reaction to danger that is facilitated by intense fear, physical restraint and perceived inability to escape. Other variables that could affect TI, such as the type and characteristics of traumatic events and personal characteristics have been little or no studied. The present study evaluated the power of these variables to predict TI in a sample of 273 college students who had experienced at least one traumatic event. Of the sample, 7.7% and 13.2% responded with TI according to the two stricter definitions adopted. Most of the variables were significantly associated with TI in univariate analyses. However, in a multiple regression analysis, only certain features of the events (occurrence of physical/sexual abuse, number of different types of events experienced and certain reactions to them (perception of how traumatic were the events, severe fear response were significant predictors of TI. Since these predictors explained only 25% of the variance, the influence of other variables -such as neuroticism, negative affectivity and perceived lack of personal control or resources to cope with traumatic events- should be investigated.

    2005-12-01

    Full Text Available Las infecciones periodontales son un conjunto de enfermedades localizadas en las encías y estructuras de soporte del diente. Están producidas por ciertas bacterias provenientes de la placa bacteriana. Estas bacterias son esenciales para el inicio de la enfermedad, pero existen factores predisponentes del hospedador y microbianos que influyen en la patogénesis de la enfermedad. La microbiota bacteriana periodontopatógena es necesaria pero no suficiente para que exista enfermedad, siendo necesaria la presencia de un hospedador susceptible. Estas enfermedades se han clasificado en gingivitis, limitadas a las encías y periodontitis, extendidas a tejidos más profundos. La clasificación de las enfermedades periodontales ha ido variando a lo largo de los años y es en el International Workshop for a Clasification of Periodontal Diseases and Conditions, en 1999, cuando se aprueba la clasificación que se expone en este trabajo. En él, se hace una revisión global de los diferentes cuadros de las enfermedades periodontales. Posteriormente, se propone el empleo de antibioterapia de utilización sistémica como la amoxicilina, amoxicilina-clavulánico y metronidazol como primera opción de tratamiento coadyuvante de estas enfermedades.

  14. Predictors of Metastatic Disease After Prostate Brachytherapy

    International Nuclear Information System (INIS)

    Purpose: To identify predictors of metastatic disease after brachytherapy treatment for prostate cancer. Methods and Materials: All patients who received either brachytherapy alone (implant) or brachytherapy in combination with external beam radiation therapy for treatment of localized prostate cancer at The Mount Sinai Hospital between June 1990 and March 2007 with a minimum follow-up of 2 years were included. Univariate and multivariable analyses were performed on the following variables: risk group, Gleason score (GS), clinical T stage, pretreatment prostate-specific antigen level, post-treatment prostate-specific antigen doubling time (PSA-DT), treatment type (implant vs. implant plus external beam radiation therapy), treatment era, total biological effective dose, use of androgen deprivation therapy, age at diagnosis, and race. PSA-DT was analyzed in the following ordinate groups: 0 to 90 days, 91 to 180 days, 180 to 360 days, and greater than 360 days. Results: We included 1,887 patients in this study. Metastases developed in 47 of these patients. The 10-year freedom from distant metastasis (FFDM) rate for the entire population was 95.1%. Median follow-up was 6 years (range, 2–15 years). The only two significant predictors of metastatic disease by multivariable analyses were GS and PSA-DT (p < 0.001 for both variables). Estimated 10-year FFDM rates for GS of 6 or less, GS of 7, and GS of 8 or greater were 97.9%, 94.3%, and 76.1%, respectively (p < 0.001). Estimated FFDM rates for PSA-DT of 0 to 90 days, 91 to 180 days, 181 to 360 days, and greater than 360 days were 17.5%, 67.9%, 74%, and 94.8%, respectively (p < 0.001). Estimated 10-year FFDM rates for the low-, intermediate-, and high-risk groups were 98.6%, 96.2%, and 86.7%, respectively. A demographic shift to patients presenting with higher-grade disease in more recent years was observed. Conclusions: GS and post-treatment PSA-DT are both statistically significant independent predictors of metastatic

    Prediction of Indian summer monsoon uses a number of climatic variables that are historically known to provide a high skill. However, relationships between predictors and predictand could be complex and also change with time. The present work attempts to use a machine learning technique to identify new predictors for forecasting the Indian monsoon. A neural network-based non-linear dimensionality reduction technique, namely, the sparse autoencoder is used for this purpose. It extracts a number of new predictors that have prediction skills higher than the existing ones. Two non-linear ensemble prediction models of regression tree and bagged decision tree are designed with identified monsoon predictors and are shown to be superior in terms of prediction accuracy. Proposed model shows mean absolute error of 4.5 % in predicting the Indian summer monsoon rainfall. Lastly, geographical distribution of the new monsoon predictors and their characteristics are discussed.

    Full Text Available Neste artigo analisa-se a contribuição dos produtos para a geração de acidentes, apresentando-se estatísticas de acidentes de trabalho, de trânsito e aeronáuticos. Além disso, para melhor ilustrar a relação entre produtos e a ocorrência de acidentes, alguns casos de acidentes ocorridos e divulgados pela mídia são comentados. As estatísticas e os casos comentados demonstram a importância do estudo dos acidentes envolvendo produtos, evidenciando que praticamente todos os acidentes estão relacionados com o uso de produtos industrializados. Então, se analisa histórica e criticamente as principais teorias de acidentes de trabalho, porque são as únicas teorias existentes em relação aos acidentes. Além delas, são analisados os diversos conceitos sobre o erro humano e sua ocorrência, pois estes são apontados como grandes causadores de acidentes. Nesta análise, se observa que os acidentes estão mais relacionados aos perigos ou às características perigosas dos produtos do que às atitudes e ao comportamento do usuário. Faz-se uma revisão dos conceitos associados aos acidentes, tais como perigo, risco, acidente e dano, a partir dos quais apresenta-se um fluxograma contendo os elementos necessários para a manifestação dos acidentes. Ao final, conclui-se que a participação dos produtos na ocorrência de acidentes é evidente e que o comportamento do usuário é dependente das características do produto e da situação na qual ele é utilizado.

  4. Multiple predictor smoothing methods for sensitivity analysis

    International Nuclear Information System (INIS)

    The use of multiple predictor smoothing methods in sampling-based sensitivity analyses of complex models is investigated. Specifically, sensitivity analysis procedures based on smoothing methods employing the stepwise application of the following nonparametric regression techniques are described: (1) locally weighted regression (LOESS), (2) additive models, (3) projection pursuit regression, and (4) recursive partitioning regression. The indicated procedures are illustrated with both simple test problems and results from a performance assessment for a radioactive waste disposal facility (i.e., the Waste Isolation Pilot Plant). As shown by the example illustrations, the use of smoothing procedures based on nonparametric regression techniques can yield more informative sensitivity analysis results than can be obtained with more traditional sensitivity analysis procedures based on linear regression, rank regression or quadratic regression when nonlinear relationships between model inputs and model predictions are present

    2005-02-01

    Mobile phone use is banned or illegal under certain circumstances and in some jurisdictions. Nevertheless, some people still use their mobile phones despite recognized safety concerns, legislation, and informal bans. Drawing potential predictors from the addiction literature, this study sought to predict usage and, specifically, problematic mobile phone use from extraversion, self-esteem, neuroticism, gender, and age. To measure problem use, the Mobile Phone Problem Use Scale was devised and validated as a reliable self-report instrument, against the Addiction Potential Scale and overall mobile phone usage levels. Problem use was a function of age, extraversion, and low self-esteem, but not neuroticism. As extraverts are more likely to take risks, and young drivers feature prominently in automobile accidents, this study supports community concerns about mobile phone use, and identifies groups that should be targeted in any intervention campaigns.

    Full Text Available En el año 2005 Martínez-Vargas formuló un sistema de cokrigeage puro heterotópico para estimar una función aleatoria regionalizada (RF Z*(x definida como la combinación lineal de n RF's univariadas Zi(x, cuyos coeficientes 1i(x son indicatrices de un set disyuntivo de categorías i. Aparentemente este modelo se contradice pues asume que las covarianzas cruzadas existen en un mismo punto, a pesar de su carácter puramente heterotópico. Para evadir dicha contradicción se redefinió el set de RF Zi(x como una única RF Z(x,i, siendo los puntos (x,i y (x,j no coincidentes si i y j no son iguales. La heterotopía fue simplemente considerada como una omisión de la RF Z(x,. en los datos y en los puntos a estimar, no impuesta por el modelo; entonces el resultado es simplemente un caso particular del cokrigeage clásico. Con esta notación se reescribió el sistema de cokrigeage clásico como el sistema de krigeage de la RF univariada Z(x,i, asumiendo que esta posee un drift definido como m(x,i,j, donde los miembros fl(x,i,j de m(x,i,j pueden ser linealmente dependientes o independientes. Bajo esta notación el sistema de krigeage se reduce a un sistema univariado, la existencia de más de una variable o la presencia de heterotropía no impone la necesidad de manipulaciones extras para definir el sistema de ecuaciones de krigeage, incrementándose la eficiencia computacional.

Less attention has been paid to alert prediabetics through determining the comprehensive predictors of diabetic cardiomyopathy (DCM and ameliorating DCM using novel approaches. DCM is recognized as asymptomatic progressing structural and functional remodeling in the heart of diabetics, in the absence of coronary atherosclerosis and hypertension. The three major stages of DCM are: (1 early stage, where cellular and metabolic changes occur without obvious systolic dysfunction; (2 middle stage, which is characterized by increased apoptosis, a slight increase in left ventricular size, and diastolic dysfunction and where ejection fraction (EF is <50%; and (3 late stage, which is characterized by alteration in microvasculature compliance, an increase in left ventricular size, and a decrease in cardiac performance leading to heart failure. Recent investigations have revealed that DCM is multifactorial in nature and cellular, molecular, and metabolic perturbations predisposed and contributed to DCM. Differential expression of microRNA (miRNA, signaling molecules involved in glucose metabolism, hyperlipidemia, advanced glycogen end products, cardiac extracellular matrix remodeling, and alteration in survival and differentiation of resident cardiac stem cells are manifested in DCM. A sedentary lifestyle and high fat diet causes obesity and this leads to type 2 diabetes and DCM. However, exercise training improves insulin sensitivity, contractility of cardiomyocytes, and cardiac performance in type 2 diabetes. These findings provide new clues to diagnose and mitigate DCM.

    Design/methodology/approach- Using a quantitative methodological approach, a survey based on SERVQUAL instrument was applied in order to evaluate local public communication. Data from a sample of 380 citizens within Western Romanian were analyzed. Specific demographic predictors that can influence citizens' satisfaction regarding the quality of communication are analyzed. Findings-By analyzing data it was possible to determine citizen satisfaction and to assess its relationship with different demographic characteristics. The results illustrate that gender does not significantly affect satisfaction, instead age, marital status, residence location (urban versus rural, income, education and occupational status of the respondents significantly affect satisfaction regarding local public communication. In addition, the findings confirm a relationship between the citizens' satisfaction and the age, income, education and occupational status of the respondents. Research limitations/implications- Owing to the budget and time limits, only a one-shot survey was conducted, therefore the comparison between “before” and “after” analysis could not be performed. In addition, further research should investigate the local public communication within national contexts. Practical implications -The adapted SERVQUAL scale may be used by institution managers to objectively assess communication performance and local authority service quality. Originality/value- There continues to be a lack of research regarding the communication process within local public administration and the effect of demographic predictors of communication satisfaction. This paper examines both the perceptions and the expectations of citizens regarding public communication. The results offer insights into residence location, age, income, education and occupational status effects on evaluations of communication satisfaction. Finally, the study contributes to studies of perceived service quality by bearing out

  12. Predictors of hyperparathyroidism in renal transplant recipients

    International Nuclear Information System (INIS)

    The changes in parathyroid hormone secretion after successful renal transplantation remain to be clearly elucidated. Our study was aimed at identifying the predictors of hyperparathyroidism in renal transplant recipients. A retrospective single center study involving 37 renal transplant recipients, with a follow-up of at least one year, was performed. All transplants were performed using kidneys from living related donors. The average age of study patients was 30+-10 years, with a male-female ratio of 1.31. The mean duration on hemodialysis (HD) prior to transplantation was 25+-18 months. All the grafts but one were functional after a mean follow-up of 41+-21 months. We noted a rapid reduction of the mean parathyroid hormone (iPTH) level from 383+-265 pg/ml before transplantation to 125+-67 pg/ml at one year and 108+-66 pg/ml at two years after transplantation (p=0.01). Bivariate analysis revealed that the level of iPTH obtained during follow-up correlated with the duration on HD (p=0.03), the serum creatinine at 24-months (p=0.013), and to the level of iPTH in the first year post transplantation (P=<0.001). Other clinical or laboratory parameters were not predictive of hyperparathyroidism after kidney transplantation. Liner regression showed that only the serum creatinine at 24-months independently correlated with the level of iPTH at last follow-up (p=0.02). Our study suggests that short duration on HD and a functional graft are the main predictors of correction of hyperparathyroidism after renal transplantation. (author)

    Purpose To determine the impact of preoperative nutritional status on the development of surgical complications following cystectomy using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). Methods We performed a retrospective review of the NSQIP 2005–2012 Participant Use Data Files. ACS-NSQIP collects data on 135 variables, including pre- and intraoperative data and 30-day post-operative complications and mortality on all major surgical procedures at participating institutions. Preoperative albumin (3.5 g/dl), weight loss 6 months before surgery (>10%), and BMI were identified as nutritional variables within the database. The overall complication rate was calculated and predictors of complications were identified using multivariable logistic regression models. Results 1,213 patients underwent cystectomy for bladder cancer between 2005–2012. The overall 30-day complication rate was 55.1% (n=668). While 14.7% (n=102) had a preoperative albumin 10% weight loss in the 6 months prior to surgery, and the mean BMI was 28 kg/m2. After controlling for age, sex, medical comorbidities, medical resident involvement, operation year, operative time and prior operation, only albumin <3.5g/dl was a significant predictor of experiencing a postoperative complication (p=0.03). This remained significant when albumin was evaluated as a continuous variable (p=0.02) Conclusions Poor nutritional status measured by serum albumin is predictive of an increased rate of surgical complications following radical cystectomy. This finding supports the importance of preoperative nutritional status in this population and highlights the need for the development of effective nutritional interventions in the preoperative setting.

    Full Text Available Ao longo da segunda metade do século XX o debate sobre desenvolvimento regional no Brasil recebeu atenção especial, principalmente, entre economistas e geógrafos. Dois enfoques principais se destacam no debate: um, que entende a promoção do desenvolvimento regional a partir da redução/eliminação das desigualdades regionais; outro, que propõe a compreensão da diversidade regional como potencialidade para o desenvolvimento de regiões. O primeiro foi e continua sendo hegemônico, evidenciado tanto em trabalhos científicos quanto em documentos norteadores das políticas públicas na área. Já o segundo evidencia-se mais claramente a partir da década de 1990, período em que o conceito de região é retomado sob um novo enfoque. Neste trabalho pretende-se explicitar o significado de cada uma dessas concepções, no intuito de contribuir para a qualificação da discussão sobre desenvolvimento regional.Palavras-chave | Desenvolvimento regional; diversidade regional; potencialidades; região.Código JEL | O18; R11; R58. REGIONAL DEVELOPMENT: REGIONAL DIVERSITY AS POTENTIALAbstractThroughout the second half of the twentieth century the debate on regional development in Brazil received special attention, especially among economists and geographers.

    The paper considers the data available in the modern literature on studies of potential molecular predictors for renal cell carcinoma (RCC). Investigations of cell death markers, namely; Bcl-2 as an inhibitor of apoptosis, are of interest. Its high expression correlates with a more favorable prognosis. Inactivation of Berclin 1 that is an authophagy indicator in intact tissues gives rise to t high risk for tumorigenesis. At the same time, high Beclin 1 expression in the tissue of the tumor itself results in the lower efficiency of performed chemotherapy. Excess annexin A2 in the tumor promotes the growth and invasion of cancer cells. Patients with tumor over-expression of SAM68 protein involved in cell proliferation have a lower overall survival rate. The lifespan of patients without distinct metastases survive significantly longer in the overexpression of epithelial cell adhesion molecule (EpCAM). High PD-L1 protein expression on the cell membrane is considered to be a potential marker of effective immunotherapy for RCC. PMID:27077146

    Research on the effects of entrepreneurial stressors is limited, especially regarding its relation to the burnout that frequently occurs in the process of starting and growing a venture. The effect of the role of entrepreneurial stressors (workload, competitive comparison, demands-of-knowledge, managing responsibility, and resource requirements) on burnout (emotional exhaustion, depersonalization, and reduced personal accomplishment) was examined in a Chinese sample of entrepreneurs. Entrepreneurial stressors emerged as a significant predictor of burnout in the process of entrepreneurship in a sample of 289 entrepreneurs (63.8% men; M age = 26.2 yr.; 39.6% of their parents have been self-employed). The findings clarify the functional relationship between entrepreneurial stressors and burnout. Entrepreneurial stressors played multiple roles. Managing responsibility was an active contributor to the sense of achievement and to emotional exhaustion. Workload was an active contributor to emotional exhaustion. Demands-of-knowledge negatively affected three of the dimensions of burnout. Theoretical and practical implications for management of the effect of these relationships are discussed. PMID:25621666

The study examines kindergarten English language outcomes in classrooms containing monolingual English speaking children and bilingual children who speak English and one other language. Data from the National Center for Early Development and Learning Multistate Study of Pre-Kindergarten (2001-2003 regarding classroom and student characteristics were used for bilingual (N = 120 and monolingual (N = 534 children. Hierarchical regression analysis (Study 1 and path analysis (Study 2 were conducted to determine the cognitive and social variables present in preschool that are most predictive of English skills in kindergarten. The results of the studies demonstrate that social variables were important for both monolingual and bilingual children. Personality variables were more predictive for monolingual children, whereas teacher relationship variables were more important for bilingual children. Simple and routine adult interaction was predictive of English skills in both groups, which may indicate the importance of implicit learning over explicit instruction in early language acquisition. The present studies found different predictors of English language skills for monolingual and bilingual kindergarteners.

    Full Text Available This study aimed to identify actual and perceived barriers to postpartum care among a probability sample of women who gave birth in Los Angeles County, California in 2007. Survey data from the 2007 Los Angeles Mommy and Baby (LAMB study (N = 4,075 were used to identify predictors and barriers to postpartum care use. The LAMB study was a cross-sectional, population-based study that examined maternal and child health outcomes during the preconception, prenatal, and postpartum periods. Multivariable analyses identified low income, being separated/divorced and never married, trying hard to get pregnant or trying to prevent pregnancy, Medi-Cal insurance holders, and lack of prenatal care to be risk factors of postpartum care nonuse, while Hispanic ethnicity was protective. The most commonly reported barriers to postpartum care use were feeling fine, being too busy with the baby, having other things going on, and a lack of need. Findings from this study can inform the development of interventions targeting subgroups at risk for not obtaining postpartum care. Community education and improved access to care can further increase the acceptability of postpartum visits and contribute to improvements in women’s health. Postpartum care can serve as a gateway to engage underserved populations in the continuum of women’s health care.

    Productivity in cold heavy old production with sand (CHOPS) is directly related to the ability of producing sand to exceed its critical drawdown pore pressure (CDPP). Sand influx is deliberately initiated into perforated oil wells in order to induce continued production of oil. The sand and oil are produced through high-porosity and high-permeability channels known as wormholes. The wormholes typically develop and grow in weak areas of the sand towards the highest pressure gradient. This paper described an analytical method that was used to predict wormhole behaviour by predicting with a high degree of accuracy poor, moderate and high producing zones by differentiating weaker unconsolidated formations from competent areas. Four profiles were used: (1) pore pressure; (2) minimum horizontal stress; (3) elastic parameters; and (4) rock strength parameters. A geomechanics model was used to account for natural stresses and sand formation strength. A sonic scanner was used to obtain acoustic data in order to determine the mechanism of anisotropy. It was concluded that the wormhole predictor will help to reduce cost by allowing producers to avoid non-producing sands as well as helping to avoid wormhole intersections that may jeopardize well production. 2 refs., 1 tab., 14 figs.

    Introducción: Las malformaciones del tubo neural (MTN) representan la segunda causa más frecuente de anomalías congénitas, luego de las cardiopatías. En este grupo se destaca el mielomeningocele (MMC) por su mayor incidencia, y por ser la más incapacitante y la más compleja entre todas las demás malformaciones del sistema nervioso c`entral (SNC). En Bolivia, como en muchos países de Sudamérica, los bajos niveles socio-culturales y la debilidad en el sistema sanitario, hacen que su incidencia y su morbilidad, sean mayores que en las naciones más desarrolladas. Material y Métodos: Se realizó un estudio retrospectivo y descriptivo de 70 casos de MMC, atendidos por un equipo multidisciplinario en el Hospital Universitario Japonés (HUJ) de Santa Cruz de la Sierra, entre 2008-2011. De ellos, 60 fueron intervenidos quirúrgicamente. Resultados: Se realizaron controles prenatales sólo en 27 mujeres (38.6%), diagnosticándose una disrafia espinal en apenas dos casos (7.4%). La edad de ingreso del MMC en su mayoría fue después de las 24 horas (65.6%), predominando su localización en la región lumbosacra (64.3%). De ellos, 67.2% eran abiertos, presentando un 32.9% un daño neurológico motor parcial mientras que 47.1% tenían paraplejia por debajo de la lesión. De los 70 casos, tres (4.3%) no fueron intervenidos, por presentar defectos congénitos severos o estado general grave. Las principales complicaciones posoperatorias inmediatas fueron: dehiscencia de sutura y/o infección de la herida (16.6%), fístula de líquido cefalorraquídeo (LCR) (10%) e infección del SNC (11.7%). La mortalidad general y postoperatoria fue de 7.1% y 3.3%, respectivamente. Al mes de vida presentaban hidrocefalia un 80% de los pacientes operados, colocándose una derivación ventriculoperitoneal (DVP) de presión media. De 9 pacientes que tuvieron un acompanamiento de dos o más años, seis presentaron una médula anclada, que fueron intervenidas quirúrgicamente. Conclusi

    This book provides a systematic approach to the design of predictor based controllers for (time-varying) linear systems with either (time-varying) input or state delays. Differently from those traditional predictor based controllers, which are infinite-dimensional static feedback laws and may cause difficulties in their practical implementation, this book develops a truncated predictor feedback (TPF) which involves only finite dimensional static state feedback. Features and topics: A novel approach referred to as truncated predictor feedback for the stabilization of (time-varying) time-delay systems in both the continuous-time setting and the discrete-time setting is built systematically Semi-global and global stabilization problems of linear time-delay systems subject to either magnitude saturation or energy constraints are solved in a systematic manner Both stabilization of a single system and consensus of a group of systems (multi-agent systems) are treated in a unified manner by applying the truncated pre...

    Full Text Available Predictors of performance in adult swimmers are constantly changing during youth especially because the training routine begins even before puberty in the modality. Therefore this study aimed to determine the group of parameters that best predict short and middle swimming distance performances of young swimmers of both genders. Thirty-three 10-to 16-years-old male and female competitive swimmers participated in the study. Multiple linear regression (MLR was used considering mean speed of maximum 100, 200 and 400 m efforts as dependent variables, and five parameters groups as possible predictors (anthropometry, body composition, physiological and biomechanical parameters, chronological age/pubic hair. The main results revealed explanatory powers of almost 100% for both genders and all performances, but with different predictors entered in MLR models of each parameter group or all variables. Thus, there are considerable differences in short and middle swimming distance, and males and females predictors that should be considered in training programs.

    Revision total knee arthroplasty (RTKA) requires preoperative planning to enable the reconstruction of bony deficiencies. The objective of this project was to identify predictors of bone loss management at RTKA based on the preoperative failure mode and patient demographics known preoperatively. We retrospectively reviewed 245 consecutive RTKA procedures in which the same revision knee system was utilized. Patient demographic and treatment data were recorded, and locations of bone loss were identified based on the reconstructive management. We identified significant predictors for use of femoral augments at all four positions. Several predictors significantly predisposed to use of a thick (>19 mm) polyethylene; however, no predictors of tibial augments were significant. Although the reconstruction of bone loss is primarily based on the intraoperative assessment, these findings may provide additional information to help the surgeon prepare for difficult revision procedures.

Identification of reliable prognostic factors for surgical outcome is important for outcome research. In this study, recent systematic reviews and meta-analyses on prediction of seizure outcome have been analyzed, and common predictors of seizure outcome or unrelated factors for temporal lobe epilepsy (TLE, lesional extratemporal lobe epilepsy (ETLE, and tuberous sclerosis complex have been identified. Clinical factors such as lesional epilepsy, abnormal magnetic resonance imaging, partial seizures, and complete resection were found to be common positive predictors, and factors such as nonlesional epilepsy, poorly defined and localized epileptic focus, generalized seizures, and incomplete resection are common negative predictors, while factors such as age at surgery and side of surgery are unrelated to seizure outcome for TLE and lesional ETLE. In addition, diagnostic neuroimaging and resection are among the most important predictors of seizure outcome. However, common predictors of seizure outcome could not be identified in nonlesional ETLE because no predictors were found to be significant in adult patients (by meta-analysis, and outcome prediction is difficult in this case. Meta-analysis of other outcomes, such as neuropsychologic outcomes, is rare due to lack of evaluation standards. Further studies on identification of reliable predictors of surgical outcomes are needed.Keywords: neuroimaging, epilepsy surgery, outcome prediction, common predictors

    Full Text Available Background: Snoring is a common problem that poses a high risk for obstructive sleep apnea (OSA. We studied the contribution of risk factors for OSA in snorers referred for full-night polysomnography (PSG. Methods: A questionnaire was administered to subjects referred for PSG in the period from April 2002 to March 2005. Results: There were 191 (84% snorers identified by 227 PSG studies. They had a mean age of 48.1±9.8 years, (age range, 23-73 years and 78.5% were males. OSA as indicated by a respiratory disturbance index (RDI of> 5 events/hour was seen in 126 (66% subjects. In males, 72.7% had OSA, with a mean RDI of 43.0±26 events/hour, versus 39% with OSA in females with a mean RDI of 27.8±26.5 events/hour (P< 0.001. The OSA group had a higher mean Epworth Sleepiness Scale (ESS (P< 0.001, a larger mean neck circumference (P< 0.01, an increased mean age (P< 0.05, and more witnessed apneas (P< 0.001 but not choking (P=0.096. The mean increase in body mass index was linked to OSA only in females (P< 0.05 but not in the overall study (P=0.507. Multivariate analysis showed that ESS, male gender, and a history of witnessed apnea were associated with OSA, while controlling for obesity, large neck circumference, age, and history of choking. Conclusion: In screening snorers for PSG, male gender, ESS and a history of witnessed apneas were the most important predictors of OSA, but other factors should be considered in referring snorers for PSG. In males, obesity did not contribute to the risk of OSA in our study population.

    Background The effects of treatment in trials with trauma-affected refugees vary considerably not only between studies but also between patients within a single study. However, we know little about why some patients benefit more from treatment, as few studies have analysed predictors of treatment outcome. Objective The objective of the study was to examine possible psychosocial predictors of treatment outcome for trauma-affected refugees. Method The participants were 195 adult refugees with posttraumatic stress disorder (PTSD) who were enrolled in a 6- to 7-month treatment programme at the Competence Centre for Transcultural Psychiatry (CTP), Denmark. The CTP Predictor Index used in the study included 15 different possible outcome predictors concerning the patients’ past, chronicity of mental health problems, pain, treatment motivation, prerequisites for engaging in psychotherapy, and social situation. The primary outcome measure was PTSD symptoms measured on the Harvard Trauma Questionnaire (HTQ). Other outcome measures included the Hopkins Symptom Check List-25, the WHO-5 Well-being Index, Sheehan Disability Scale, Hamilton Depression and Anxiety Scales, the somatisation scale of the Symptoms Checklist-90, Global Assessment of Functioning scales, and pain rated on visual analogue scales. The relations between treatment outcomes and the total score as well as subscores of the CTP Predictor Index were analysed. Results Overall, the total score of the CTP Predictor Index was significantly correlated to pre- to post treatment score changes on the majority of the ratings mentioned above. While employment status was the only single item significantly correlated to HTQ-score changes, a number of single items from the CTP Predictor Index correlated significantly with changes in depression and anxiety symptoms, but the size of the correlation coefficients were modest. Conclusions The total score of the CTP Predictor Index correlated significantly with outcomes on most

    Full Text Available Abstract Background Food environment studies have focused on ethnic and income disparities in food access. Few studies have investigated distance travelled for food and did not aim to inform the geographic scales at which to study the relationship between food environments and obesity. Further, studies have not considered neighborhood design as a predictor of food purchasing behavior. Methods Atlanta residents (N = 4800 who completed a travel diary and reported purchasing or consuming food at one of five food locations were included in the analyses. A total of 11,995 food-related trips were reported. Using mixed modeling to adjust for clustering of trips by participants and households, person-level variables (e.g. demographics, neighborhood-level urban form measures, created in GIS, and trip characteristics (e.g. time of day, origin and destination were investigated as correlates of distance travelled for food and frequency of grocery store and fast food outlet trips. Results Mean travel distance for food ranged from 4.5 miles for coffee shops to 6.3 miles for superstores. Type of store, urban form, type of tour, day of the week and ethnicity were all significantly related to distance travelled for food. Origin and destination environment, type of tour, day of week, age, gender, income, ethnicity, vehicle access and obesity status were all significantly related to visiting a grocery store. Home neighborhood environment, day of week, type of tour, gender, income, education level, age, and obesity status were all significantly related to likelihood of visiting a fastfood outlet. Conclusions The present study demonstrated that people travel sizeable distances for food and this distance is related to urban. Results suggest that researchers need to employ different methods to characterize food environments than have been used to assess urban form in studies of physical activity. Food is most often purchased while traveling from locations other

  12. On Finding Predictors for Arbitrary Families of Processes

    2009-01-01

    The problem is sequence prediction in the following setting. A sequence $x_1,...,x_n,...$ of discrete-valued observations is generated according to some unknown probabilistic law (measure) $\\mu$. After observing each outcome, it is required to give the conditional probabilities of the next observation. The measure $\\mu$ belongs to an arbitrary but known class $C$ of stochastic process measures. We are interested in predictors $\\rho$ whose conditional probabilities converge (in some sense) to the "true" $\\mu$-conditional probabilities if any $\\mu\\in C$ is chosen to generate the sequence. The contribution of this work is in characterizing the families $C$ for which such predictors exist, and in providing a specific and simple form in which to look for a solution. We show that if any predictor works, then there exists a Bayesian predictor, whose prior is discrete, and which works too. We also find several sufficient and necessary conditions for the existence of a predictor, in terms of topological characterizati...

  13. Electricity curtailment behaviors in Greek households: Different behaviors, different predictors

    International Nuclear Information System (INIS)

    Highlights: • We study the self-reported energy (electricity) curtailment behaviors of Greek households (N=285). • We find that the curtailment behaviors are distinct and should be studied/analyzed separately. • ‘Age’, ‘Gender’ and ‘Perceived Behavioral Control’ are statistically significant predictors of most behaviors. • The demographic/structural and the psychological predictors contribute significantly explain the variance of the behaviors. • The cluster of moral predictors does not contribute statistically significantly to the explained variance. - Abstract: This paper argues that electricity ‘curtailment’ behaviors (i.e. frequent and/or low cost or free energy saving behaviors) in households are distinct from one another and they thus should be analyzed and promoted. We test this claim with data from telephone interviews with Greek households in the capital city of Athens (N=285), analyzing the impact of a number of demographical/structural, psychological (based on the Theory of Planned Behavior) and moral (based on norms’ activation) predictors though hierarchical binary logistic regression modeling. We find that that each electricity curtailment behavior depends on a different mix of predictors with ‘Age’, ‘Gender’ and ‘Perceived Behavioral Control’ being statistically significant for most behaviors. Overall, the psychological and the demographical/structural clusters of variables substantially contribute to the explained variance of electricity curtailment behaviors. The moral cluster's contribution is not statistically significant since moral concerns are largely interwoven in the psychological constructs

    2008-05-01

    Full Text Available We examined the demographic characteristics of couples, ovarian response and sperm quality to determine the predictors of clinical fertilization in IVF cycles. A descriptive and analytic study was conducted using data and biologic specimens obtained Fatemeh-Alzahra of Babol infertility center from 2004 to 2005. Only data from 315 women who had medical indication for conventional IVF treatment were included in the analysis. Treatment using ICSI was excluded. In the univariate analysis, the following variables affected on fertilization rate: the length of infertility, the number of IVF cycle, basal LH serum on 2 days, the number of administration of hMG, the duration of ovarian stimulation, the number of follicles, the number of oocytes retrieved, the number of oocytes stage II and III, sperm count, sperm motility, sperm grading III and IV. In the multivariate analysis, the strongest predictor of positive fertilization was the mean number of oocytes retrieved. Also, the mean number of oocytes stage II and stage III were positive predictors of fertilization. The mean of basal LH serum on day 2 and the mean duration of ovarian stimulation were negative predictors of fertilization Ovarian response to gonadotropins and the quality of oocytes were main predictors of fertilization. Although some parameters of sperm quality were significant variables of fertilization rate in univariate analysis, in multivariate analysis one's effects were negligible. This information should be used when selecting couples for IVF cycles or oocytes for fertilization to raise the rate of clinical fertilization.

    Full Text Available The aim of the investigation is to reveal predictors of stress pathogenicity and to study the possibility of their application for monitoring rehabilitation effectiveness in individuals with distress consequences. Materials and Methods. The study involved 175 males who had suffered once traumatic stress, associated with professional activities. Anamnestic, instrumental and laboratory methods of investigation were used along with psychological techniques and calculation of integral indexes. Besides, to investigate the possibility of applying the predictors for monitoring sanogenetic changes the studied individuals participated in standard rehabilitation programs according to the methods developed by Pogodina et al. Results. There have been revealed the most informative predictors of stress pathogenicity and therapy efficacy for homeostatic post-stress disorders resulting from interaction of the organism with the environment. It has been established that in individuals with a single exposure to traumatic stress the most informative predictors of stress pathogenicity are vegetative disturbances and sexual status disorders associated with them, such as sexual dysfunctions and family-sexual disharmonies. Complex evaluation of the revealed predictors is possible when applying integral indexes based on measuring vegetative and psychosomatic parameters. It is quite easy to implement and at the same time informative not only for assessment of patients initial condition but also for monitoring rehabilitation effectiveness in individuals with distress consequences.

Los participantes, 197 bailarines vocacionales, completaron los cuestionarios con las variables clave de interés. Los resultados revelaron que las percepciones del apoyo a la autonomía ofrecidas por el profesor de danza actuó como predictor positivo de la motivación autónoma (motivación intrínseca, regulación integrada y regulación identificada y como predictor negativo de la motivación controlada (regulación externa y regulación introyectada y de la no motivación. A su vez, la intención de seguir participando en danza fue predicha positivamente por la motivación autónoma y negativamente por la motivación controlada y por la no motivación. En el segundo modelo, la incorporación del burnout como antecedente inmediato de la intención, aumentó la varianza explicada de la intención de continuar participando. La motivación autónoma actuó como predictor negativo del burnout mientras que la motivación controlada y la no motivación presentaron asociaciones positivas con éste. A su vez el burnout se mostró como predictor negativo de la intención de continuar en danza. Los resultados ofrecen apoyo a la teoría de la autodeterminación y destacan los beneficios de promover la motivación autónoma a través de interacciones de apoyo a la autonomía, en un contexto tan complejo como la danza, en el que se valoran tanto los aspectos técnicos como los artísticos.AbstractGrounded in the framework of self-determination theory (Deci y Ryan, 1985; 2000, socio-contextual and motivational predictors of intentions to continue participation in dance, and the role of burnout in these relationships were studied through the testing of two

Éstas reflexiones intentan contribuir a desnaturalizar y visibilizar la complejidad de los contextos de interacción, considerando que abarcan distintas dimensiones y aspectos —tales como posición de los interlocutores en la estructura social, expectativas individuales, experiencias y relaciones previas de los sujetos, y recursos materiales y simbólicos en intermediación—, enfatizando así el carácter situacional y dinámico de esas relaciones de interlocución.A la luz de los actuales debates de la crítica cultural y en un intento por contribuir a los estudios de la Etnografía Colaborativa, el objetivo de este artículo es exponer y describir comparativamente lo que entendemos como performances de campo, situando como objeto de análisis la experiencia etnográfica en sí misma. Entendiendo el trabajo etnográfico como proceso y texto, identificamos tres grandes nudos críticos, reunidos en tres escenas etnográficas, que analizamos como una red multisituada de mediaciones e interrelaciones.

  10. Poststroke epilepsy in the Copenhagen stroke study: incidence and predictors

    DEFF Research Database (Denmark)

    Kammersgaard, Lars Peter; Olsen, Tom Skyhøj

    Poststroke epilepsy (PSE) is a feared complication after stroke and is reported in 3% to 5% of stroke survivors. In this study we sought to identify incidence and predictors of PSE in an unselected stroke population with a follow-up period of 7 years. The study was community-based and comprises a...... size on computed tomography scans, stroke subtype, localization, stroke risk factor profile, and early seizures) in univariate analyses. Independent predictors of PSE were identified through multiple logistic regression analyses. Overall, 38 patients (3.2%) developed PSE. Univariately, PSE was...... associated with younger age, intracerebral hemorrhage, and larger lesions. PSE was less frequently associated with atrial fibrillation and ischemic heart disease. In the final multiple regression model for the dependent variable PSE, independent predictors were younger age (odds ratio [OR] 1.7/10 years; 95...

    Full Text Available Few studies have explored predictors of early childhood anxiety.To determine the prenatal, postnatal, and early life predictors of childhood anxiety by age 5.Population-based, provincial administrative data (N = 19,316 from Manitoba, Canada were used to determine the association between demographic, obstetrical, psychosocial, medical, behavioral, and infant factors on childhood anxiety.Risk factors for childhood anxiety by age 5 included maternal psychological distress from birth to 12 months and 13 months to 5 years post-delivery and an infant 5-minute Apgar score of ≤7. Factors associated with decreased risk included maternal age < 20 years, multiparity, and preterm birth.Identifying predictors of childhood anxiety is a key step to early detection and prevention. Maternal psychological distress is an early, modifiable risk factor. Future research should aim to disentangle early life influences on childhood anxiety occurring in the prenatal, postnatal, and early childhood periods.

    2016-01-01

    This study examines the differences in the social determinants of health and chronic health conditions of immigrants and nonimmigrants. The logistic regression results indicate that employment, education, poverty, residential status, and neighborhood safety have strong influence on the health of immigrants and native-born Americans; however, gender and place of residence are significant to only nonimmigrant health. For chronic health conditions, age and employment status are significant predictors for immigrants whereas race/ethnicity, age, gender, insurance coverage, and education are important predictors of chronic health conditions among nonimmigrants. Neighborhood safety, English proficiency, and marital status were not significant determinants of the health conditions of both subgroups. The study points to the importance of education, poverty/income, and neighborhood safety as essential determinants of immigrant and nonimmigrant health. However, there are variations in the health predictors for each group. PMID:26963922

    2016-05-01

    There is an extensive body of research on the determinants of disaster preparedness at the individual and household levels. The same cannot be said for the organizational level. Hence, the purpose of this study is to shed light on the predictors of organizational preparedness for natural disasters. Since leaders of organizations have an incentive to overstate their level of preparedness and because surveys of organizational leaders suffer from selection bias and low response rates, we take the novel approach of interviewing employees about the organizations that employ them. Using an online survey, we collected information from a national sample of 2,008 U.S. employees and estimated the predictors of preparedness at the organizational level. We find, among other results, that organization size (facility level) is a consistent predictor of preparedness at the organizational level. We conclude with policy recommendations and outline an agenda for future research on organizational preparedness for natural disasters. PMID:26332326

    2012-01-01

    Patients with extensive or complicated Crohn's disease (CD) at diagnosis should be treated straightaway with immunosuppressive therapy according to the most recent guidelines.In patients with localized and uncomplicated CD at diagnosis,early use of immunosuppressive therapy is debated for preventing disease progression and limiting the disabling clinical impact.In this context,there is a need for predictors of benign or unfavourable subsequent clinical course,in order to avoid over-treating with risky drugs those patients who would have experienced spontaneous mid-term asymptomatic disease without progression towards irreversible intestinal lesions.At diagnosis,an age below 40 years,the presence of perianal lesions and the need for treating the first flare with steroids have been consistently associated with an unfavourable subsequent 5-year or 10-year clinical course.The positive predictive value of unfavourable course in patients with 2 or 3 predictors ranges between 0.75 and 0.95 in population-based and referral centre cohorts.Consequently,the use of these predictors can be integrated into the elements that influence individual decisions.In the CD postoperative context,keeping smoking and history of prior resection are the strongest predictors of disease symptomatic recurrence.However,these clinical predictors alone are not as reliable as severity of early postoperative endoscopic recurrence in clinical practice.In ulcerative colitis (UC),extensive colitis at diagnosis is associated with unfavourable clinical course in the first 5 to 10 years of the disease,and also with long-term colectomy and colorectal inflammation-associated colorectal cancer.In patients with extensive UC at diagnosis,a rapid step-up strategy aiming to achieve sustained deep remission should therefore be considered.At the moment,no reliable serological or genetic predictor of inflammatory bowel disease clinical course has been identified.

    The Family of Assessment Device and clinical data for 60 stroke patients were used to predict outcome at six months and one year poststroke. Ratings of behavior control and affective responsiveness of the family predicted number of days of rehospitalization during the study. Problem solving scores, family communication skills, and patient self-care ability predicted family-rated patient adjustment. Family function was a better predictor of hospital stay than baseline ratings of typical predictors of stroke outcome. Family function represents an area for potential stroke intervention that may have more relevance to efficient health care delivery and the clinical status of stroke patients than has previously been noted.

    Stringent admission criteria exist for nursing programs in the United States, but better predictors of success are needed to reduce student attrition. Research indicates that organized music experiences are associated with greater academic success. This exploratory study examined the association between early music experiences and undergraduate nursing student success. Findings suggest that students with a music background were more likely to graduate, have higher grade point averages, and pass the licensure examination. Previous music education might be considered as an additional predictor of nursing student success. PMID:23778040

    RESUMO

    A educação formal para o trabalho, em nível superior, começa a enfrentar uma concorrência inusitada: as universidades corporativas, surgidas das experiências de programas de treinamento e desenvolvimento profissionais corporativos e da constatação de que a universidade não prepara adequadamente para o trabalho. O conceito de universidade corporativa surgiu nos EUA, em 1995, quando a General Eletric criou a Cotronville. Mas foi só a partir da década de 80 que se assistiu a um aumento considerável destes novos espaços de formação. Outro componente que contribuiu para o rápido crescimento das universidades corporativas é a necessidade de contínua aprendizagem, como conseqüência das vertiginosas mudanças no mundo do trabalho, em razão dos avanços tecnológicos permanentes e do processo de globalização da economia. As universidades corporativas surgem como solução para o alinhamento das iniciativas de treinamento com a estratégia da organização e de criação de vantagem competitiva, por meio de aprendizado permanente.

  10. Optimising predictor domains for spatially coherent precipitation downscaling

    Science.gov (United States)

    Radanovics, S.; Vidal, J.-P.; Sauquet, E.; Ben Daoud, A.; Bontron, G.

    2012-04-01

    Relationships between local precipitation (predictands) and large-scale circulation (predictors) are used for statistical downscaling purposes in various contexts, from medium-term forecasting to climate change impact studies. For hydrological purposes like flood forecasting, the downscaled precipitation spatial fields have furthermore to be coherent over possibly large basins. This thus first requires to know what predictor domain can be associated to the precipitation over each part of the studied basin. This study addresses this issue by identifying the optimum predictor domains over the whole of France, for a specific downscaling method based on a analogue approach and developed by Ben Daoud et al. (2011). The downscaling method used here is based on analogies on different variables: temperature, relative humidity, vertical velocity and geopotentials. The optimum predictor domain has been found to consist of the nearest grid cell for all variables except geopotentials (Ben Daoud et al., 2011). Moreover, geopotential domains have been found to be sensitive to the target location by Obled et al. (2002), and the present study thus focuses on optimizing the domains of this specific predictor over France. The predictor domains for geopotential at 500 hPa and 1000 hPa are optimised for 608 climatologically homogeneous zones in France using the ERA-40 reanalysis data for the large-scale predictors and local precipitation from the Safran near-surface atmospheric reanalysis (Vidal et al., 2010). The similarity of geopotential fields is measured by the Teweles and Wobus shape criterion. The predictive skill of different predictor domains for the different regions is tested with the Continuous Ranked Probability Score (CRPS) for the 25 best analogue days found with the statistical downscaling method. Rectangular predictor domains of different sizes, shapes and locations are tested, and the one that leads to the smallest CRPS for the zone in question is retained. The

  11. Predictors of a positive baseline bone scan in breast cancer

    International Nuclear Information System (INIS)

    The aim of this retrospective study was to determine the predictors of a positive bone scan in female patients with breast carcinoma. The participants were 126 females with newly diagnosed breast carcinoma and a baseline bone scan. Patients who had started treatment before their bone scan were excluded. Bone scans were assessed as 'no metastases' or 'definite skeletal metastases' without knowledge of the patient's predictor variables. Those with 'possible metastases' were correlated with other available imaging and clinical information, and re-categorised as 'no metastases' or 'definite skeletal metastases'. Results were compared with predictor variables. Significant predictors were increasing age, a higher histopathological grading and positive progesterone receptor status following a forward-stepwise logistic regression analysis. Axillary nodal status, tumour size and oestrogen receptor status did not correlate with a positive bone scan. Not every patient needs a staging bone scan. This study is important because it predicts the need for baseline scintigraphy for specific patients in whom skeletal metastases are more likely to be present or to develop. The findings are particularly valuable in times of worldwide resource scarcity and evolving surgical practice. Copyright (2005) Blackwell Publishing Asia Pty Ltd

  16. A New Perspective for the Calibration of Computational Predictor Models.

    Energy Technology Data Exchange (ETDEWEB)

    Crespo, Luis Guillermo

    2014-11-01

    This paper presents a framework for calibrating computational models using data from sev- eral and possibly dissimilar validation experiments. The offset between model predictions and observations, which might be caused by measurement noise, model-form uncertainty, and numerical error, drives the process by which uncertainty in the models parameters is characterized. The resulting description of uncertainty along with the computational model constitute a predictor model. Two types of predictor models are studied: Interval Predictor Models (IPMs) and Random Predictor Models (RPMs). IPMs use sets to characterize uncer- tainty, whereas RPMs use random vectors. The propagation of a set through a model makes the response an interval valued function of the state, whereas the propagation of a random vector yields a random process. Optimization-based strategies for calculating both types of predictor models are proposed. Whereas the formulations used to calculate IPMs target solutions leading to the interval value function of minimal spread containing all observations, those for RPMs seek to maximize the models' ability to reproduce the distribution of obser- vations. Regarding RPMs, we choose a structure for the random vector (i.e., the assignment of probability to points in the parameter space) solely dependent on the prediction error. As such, the probabilistic description of uncertainty is not a subjective assignment of belief, nor is it expected to asymptotically converge to a fixed value, but instead it is a description of the model's ability to reproduce the experimental data. This framework enables evaluating the spread and distribution of the predicted response of target applications depending on the same parameters beyond the validation domain (i.e., roll-up and extrapolation).

Foi realizada uma verificação empírica com uma amostra integrada por 196 profissionais argentinos (97 médicos e 99 enfermeiros. A amostra respondeu uma bateria desenvolvida para avaliar estressores, enfrentamento, bem-estar e satisfação laboral. Foram realizadas análises descritivas, correlacionais e de regressão múltipla. Os resultados obtidos indicaram que os estressores que mais afligem aos profissionais da saúde são a sobrecarga, a falta de apoio e a percepção de injustiça organizacional. Tanto a estratégia de resolução de problemas como a de distanciamento surgiram como potenciadoras de satisfação e bem-estar. As variáveis que melhor explicaram a satisfação laboral foram a intenção de permanecer no cargo, a quantidade de horas de trabalho semanal e o apoio do grupo familiar. São apresentadas sugestões para futuras investigações na área.The objectives of this research were: (a to identify the major stressors and the coping strategies commonly used by health professionals; (b to explore the links among health care stressors, subjective wellbeing and job satisfaction; and (c to individualize the explanatory variables of care job satisfaction.

ObjetivoEvaluar la sobrevida alejada del recambio valvular aórtico biológico, la calidad de vida, las tasas de reinternación y reintervención, así como identificar predictores para tales eventos.Material y métodosSe analizó una población sometida a cirugía aórtica aislada o combinada con revascularización, con modelos biológicos, entre junio de 1996 y diciembre de 2005. Excluidos los fallecidos a los 30 días, se analizaron 256 pacientes, con un seguimiento del 94,2% a 1.158 días.ResultadosLa sobrevida global fue del 94,8%, 88,6%, 85% y 82,4% a 1, 3, 5 y 7 años; sobrevida libre la mortalidad cardíaca, fue del 97,2%, 94,6%, 91,2% y 89,4%, respectivamente. La sobrevida libre de reinternación fue del 86%, 75,7%, 70,6% y 65,9% para igual período. La sobrevida libre de reintervención fue del 97,4%, 95,2%, 92,1% y 92,1% a 1, 3, 5 y 7 años.

    Full Text Available Against the background of demographic change and skill shortages continuing vocational training is of great significance in Germany. However, the training effectiveness is mostly assessed only at the end of a training program or several months after the training. Since in continuing vocational training the two contexts learning field (training and performance field (work context act simultaneously, the presented study investigated whether there are already situations in the work context which allow the application of newly acquired knowledge in parallel with the training. The main focus lies in the identification of predictors of learning transfer that takes place alongside the training participation and in the investigation of their causal relationships. Using structural equation modelling five latent variables were identified which have a significant effect on learning transfer parallel to the training – the so called collateral learning transfer. These five predictors explain together 62% of the variance of collateral learning transfer (gathered as performance improvement at work.

  20. Encke-Beta Predictor for Orion Bum Targeting and Guidance

    Robinson, Shane; Scarritt, Sara; Goodman, John L.

    2016-01-01

    The state vector prediction algorithm selected for Orion on-board targeting and guidance is known as the Encke-Beta method. Encke-Beta uses a universal anomaly (beta) as the independent variable, valid for circular, elliptical, parabolic, and hyperbolic orbits. The variable, related to the change in eccentric anomaly, results in integration steps that cover smaller arcs of the trajectory at or near perigee, when velocity is higher. Some burns in the EM-1 and EM-2 mission plans are much longer than burns executed with the Apollo and Space Shuttle vehicles. Burn length, as well as hyperbolic trajectories, has driven the use of the Encke-Beta numerical predictor by the predictor/corrector guidance algorithm in place of legacy analytic thrust and gravity integrals.

    This paper reviews findings from 58 prospective studies of illicit substance use (ISU) among adolescents. It arranges 384 findings according to three types of influence (viz., social, attitudinal, and intrapersonal) and four levels of influence (viz., ultimate, distal, proximal, and immediate). The bulk of evidence reconfirms the importance of several predictors of ISU (e.g., intentions and prior substance-related behavior, friendship patterns and peer behaviors, absence of supportive parents, psychological temperament), reveals that a few variables thought to be well-established predictors may not be (e.g., parental behaviors, parental permissiveness, depression, low self-esteem), and uncovers several variables where findings were either sparse or inconsistent (e.g., the role of public policies concerning ISU, mass media depictions of ISU, certain parenting styles, affective states, perceptions of parental disapproval for ISU, and substance-specific refusal skills). Directions for future research are discussed. PMID:9818990

    Our study examines whether defense styles and separate defenses in depressed adolescent outpatients predict adult personality disorders (PDs). We obtained data from consecutive adolescent outpatients who participated in the Adolescent Depression Study at baseline and at the 8-year follow-up (N = 140). Defense styles were divided into mature, neurotic, image-distorting, and immature and a secondary set of analyses were made with separate defenses as predictors of a PD diagnosis. Neurotic, image-distorting, and immature defense styles in adolescence were associated with adulthood PDs. Neurotic defense style associated with cluster B diagnosis and image-distorting defense style associated with cluster A diagnosis. Separate defenses of displacement, isolation, and reaction formation were independent predictors of adult PD diagnosis even after adjusting for PD diagnosis in adolescence. Defense styles and separate defenses predict later PDs and could be used in the focusing of treatment interventions for adolescents. PMID:26894315

    Full Text Available INTRODUCTION: It is known that mechanical ventilation and many of its features may affect the evolution of inspiratory muscle strength during ventilation. However, this evolution has not been described, nor have its predictors been studied. In addition, a probable parallel between inspiratory and limb muscle strength evolution has not been investigated. OBJECTIVE: To describe the variation over time of maximal inspiratory pressure during mechanical ventilation and its predictors. We also studied the possible relationship between the evolution of maximal inspiratory pressure and limb muscle strength. METHODS: A prospective observational study was performed in consecutive patients submitted to mechanical ventilation for > 72 hours. The maximal inspiratory pressure trend was evaluated by the linear regression of the daily maximal inspiratory pressure and a logistic regression analysis was used to look for independent maximal inspiratory pressure trend predictors. Limb muscle strength was evaluated using the Medical Research Council score. RESULTS: One hundred and sixteen patients were studied, forty-four of whom (37.9% presented a decrease in maximal inspiratory pressure over time. The members of the group in which maximal inspiratory pressure decreased underwent deeper sedation, spent less time in pressure support ventilation and were extubated less frequently. The only independent predictor of the maximal inspiratory pressure trend was the level of sedation (OR=1.55, 95% CI 1.003 - 2.408; p = 0.049. There was no relationship between the maximal inspiratory pressure trend and limb muscle strength. CONCLUSIONS: Around forty percent of the mechanically ventilated patients had a decreased maximal inspiratory pressure during mechanical ventilation, which was independently associated with deeper levels of sedation. There was no relationship between the evolution of maximal inspiratory pressure and the muscular strength of the limb.

    During orthotopic liver transplantation (OLT), a marked decrease in blood pressure following unclamping of the portal vein and liver reperfusion is frequently observed and is termed postreperfusion syndrome (PRS). The predictive factors and clinical consequences of PRS are not fully understood. The goal of this study was to identify predictors of PRS and morbidity/mortality associated with its occurrence during OLT in patients with cirrhosis. During a 3-year period, all consecutive OLT procedures performed in patients with cirrhosis were studied. Exclusion criteria were OLT for acute liver failure, early retransplantation, combined liver/kidney transplantation, and living-donor related transplantation. PRS was defined as a decrease in the mean arterial pressure of more than 30% of the value observed in the anhepatic stage, for more than 1 minute during the first 5 minutes after reperfusion of the graft. Transplantation was performed with preservation of the inferior vena cava with or without temporary portocaval shunt. Associations between PRS and donor and recipient demographic data, recipient operative and postoperative outcomes were tested with bivariate statistics. Independent predictors of PRS were determined in multivariable logistic regression analysis. Of the 75 patients included in the study, 20 patients (25%) developed PRS. In a multivariable analysis, absence of a portocaval shunt [odds ratio (95% confidence interval) = 4.42 (1.18-17.6)] and duration of cold ischemia [odds ratio (95% confidence interval) = 1.34 (1.07-1.72)] were independent predictors of PRS. Patients who experienced PRS displayed more postoperative renal failure and lower early (<15 days after OLT) survival (80% versus 96%; P = 0.04). In conclusion, the absence of portocaval shunt and the duration of cold ischemia were independent predictors of intraoperative PRS. PRS was associated with significant adverse postoperative outcome. These results provide realistic clinical targets to

    After a violent conflict many post-conflict communities remain ethnically divided and normalization of the inter-group relations is hindered not only by in-group norms and interpretation of past events, but also by collective guilt. Although collective guilt has proved to be an important indicator of post-conflict social repair, more research is needed to define its predictors. This study, conducted in an ethnically divided community, confirmed that collective guilt acceptance and collective ...

    2013-01-01

    This paper addresses the adaptive synchronization of complex dynamical networks with nonlinear dynamics. Based on the Lyapunov method, it is shown that the network can synchronize to the synchronous state by introducing local adaptive strategy to the coupling strengths. Moreover, it is also proved that the convergence speed of complex dynamical networks can be increased via designing a state predictor. Finally, some numerical simulations are worked out to illustrate the analytical results.

    Many chaotic time series show non-Gaussian distribution, and non-Gaussianity can be characterized not only by higher-order cumulants but also by negative entropy.Since negative entropy can be accurately approximated by some special non-polynomial functions, which also can form an orthogonal system, these functions are used to construct an adaptive predictor to replace higher-order cumulants.Simulation shows the algorithm performs well for different chaotic systems.

    Full Text Available Background: Meningeal tuberculosis (TB has higher mortality compared to other forms of central nervous system TB. However, data on predictors of mortality is limited. Aims: To determine the predictors of mortality in patients with meningeal TB. Materials and Methods: This study retrospectively analyzed the data of patients admitted with a diagnosis of meningeal TB between January 2006 and December 2008. Thwaites′ index score of four or less was used for the diagnosis of meningeal TB which is a weighted diagnostic index score for dichotomised clinical variables. Predictors of mortality were analyzed separately for both patients with human immunodeficiency virus (HIV infection and without. Statistical Analysis: Univariate analysis and multinomial logistic regression was done. Results: Univariate analysis showed age >40 years, Glasgow Coma Scale (GCS score 40 years was a risk factor for mortality when HIV patients were included (P=0.049 as well as when they were excluded (P=0.048. CSF protein ͳ 60 mg% was found to be a significant risk factor when both HIV seropositive persons (P=0.011 as well as seronegative persons (P=0.004 were included. HIV seropositivity, steroid treatment or delay in treatment did not affect mortality. Conclusions: Identification of factors predictive of in-hospital mortality will help to prognosticate patients with meningeal TB at the time of admission.

  11. Kernel Averaged Predictors for Spatio-Temporal Regression Models.

    Heaton, Matthew J; Gelfand, Alan E

    2012-12-01

    In applications where covariates and responses are observed across space and time, a common goal is to quantify the effect of a change in the covariates on the response while adequately accounting for the spatio-temporal structure of the observations. The most common approach for building such a model is to confine the relationship between a covariate and response variable to a single spatio-temporal location. However, oftentimes the relationship between the response and predictors may extend across space and time. In other words, the response may be affected by levels of predictors in spatio-temporal proximity to the response location. Here, a flexible modeling framework is proposed to capture such spatial and temporal lagged effects between a predictor and a response. Specifically, kernel functions are used to weight a spatio-temporal covariate surface in a regression model for the response. The kernels are assumed to be parametric and non-stationary with the data informing the parameter values of the kernel. The methodology is illustrated on simulated data as well as a physical data set of ozone concentrations to be explained by temperature. PMID:24010051

    Full Text Available Weight loss from exercise-induced energy deficits is usually less than expected. The objective of this systematic review was to investigate predictors of energy compensation, which is defined as body energy changes (fat mass and fat-free mass over the total amount of exercise energy expenditure. A search was conducted in multiple databases without date limits. Of 4745 studies found, 61 were included in this systematic review with a total of 928 subjects. The overall mean energy compensation was 18% ± 93%. The analyses indicated that 48% of the variance of energy compensation is explained by the interaction between initial fat mass, age and duration of exercise interventions. Sex, frequency, intensity and dose of exercise energy expenditure were not significant predictors of energy compensation. The fitted model suggested that for a shorter study duration, lower energy compensation was observed in younger individuals with higher initial fat mass (FM. In contrast, higher energy compensation was noted for younger individuals with lower initial FM. From 25 weeks onward, energy compensation was no longer different for these predictors. For studies of longer duration (about 80 weeks, the energy compensation approached 84%. Lower energy compensation occurs with short-term exercise, and a much higher level of energy compensation accompanies long-term exercise interventions.

    Full Text Available It is considered that political knowledge is one of the most prominent features of democratic citizenship, which makes its analysis especially relevant in a democratising society. This paper explores the predictors and correlates of youth political knowledge in Serbia. Political knowledge was measured by 12 multiple-choice questions pertaining to three areas: everyday politics, the rules of political game and foreign politics. Research participants were 788 fourth-grade students from 25 Belgrade secondary schools. The results show that the level of youth political knowledge is generally low and unevenly distributed among students. Its main predictors are interest in politics, academic achievement, gender and father’s interest in politics. Other predictors that are usually regarded as very important (e.g. socioeconomic status, civic education proved to be non-significant. Although political knowledge is positively correlated with political tolerance, political activism and diffuse political support, the coefficients are very low. The concluding part discusses possible causes of the obtained results.

    2009-12-01

    A growing body of literature supports the contention that both women and men employ various seductive, manipulative, intoxication, and even forceful tactics of sexual coercion to obtain sexual contact from unwilling partners. Although the self-reported coercive behavior of men and women may appear similar in many respects, predictors of such behavior seem to vary in important ways across gender. In addition to examining the prevalence of coercive behaviors reported across gender, the present study examined the extent to which four variables found in models of male sexual coercion predicted self-reported use of sexual coercion in a sample (n = 186) of college men and women: prior sexual abuse, sexual dominance, sociosexuality, and sexual compulsivity. Although prior sexual abuse seemed to be part of a cycle of sexual coercion among both men and women, key predictors of sexual coercion among men were sexual dominance and sociosexuality, whereas the key predictor of sexual coercion among women was sexual compulsivity. These findings support the notion that whereas men may behave coercively to obtain or maintain an impersonal sense of power and control, women may behave coercively to achieve some level of interpersonal connection when feeling out of control.

    Full Text Available Background: dyslipidemia and obesity are key independent modifiable risk factors for many non communicable chronic diseases. Patterns of association between these factors may help prevention and control. This study aims to assess the association between lipids profile and obesity among adults in Kingdom of Saudi Arabia and identify anthropometric predictors of dyslipidemia.Methods: data were collected and analyzed from a cross-sectional study using WHO STEPwise approach that included 4 990 Saudi adults aged 15- 64 years selected by stratified, multistage, cluster random sampling technique. Lipid profiles (cholesterol categories and triglycerides were determined spectrophotometrically by colorimetric biochemical methods. Obesity was determined by calculation of body mass index (BMI=Kg/m2, waist and hip circumferences and ratio and waist to height ratio.Results: the overall prevalence of obesity ranged from 33.8 to 44.4 % and the overall dyslipidemia prevalence ranged from about 25 to 44% depending on type of dyslipidemia and anthropometrics used. Prevalence of dyslipidemia and mean concentration of lipids profile were generally significantly higher in obese than non obese. The indicator waist/height ratio was the significant predictor for all types of dyslipidemia and all levels of serum lipids.Conclusions: the prevalence dyslipidemia and obesity are high and they are positively associated. Waist/height ratio was the most important predictor of dyslipidemia among adults.

    2015-01-01

    Jamaica has acquired an international reputation for strong antigay prejudice, incidents of antigay violence, and outspoken, antigay public figures. In recent years, national and international gay rights groups have attempted to improve this situation. However, these efforts have not been based on an empirical analysis of the factors underlying Jamaican antigay bias, which is essential for developing effective prejudice-reducing strategies. Using data collected in two large-scale national surveys in 2011 and 2012 (N 2011 = 997, N 2012 = 945), we investigated predictors of Jamaican antigay prejudice, including age, gender, religious affiliation, education, income, and a preference for dancehall music. We also examined changes in reported antigay bias between 2011 and 2012 after accounting for other predictors. All proposed variables predicted some aspect of antigay prejudice, though sometimes in unexpected ways. Male gender emerged as a particularly important predictor. We discuss the strengths and limitations of our design and the implications of our findings for prejudice-reduction strategies in Jamaica. PMID:24483715

    Identifying the predictors of smoking in one of the top cigarette-consuming countries in the world is a vital step in smoking prevention. A cross-sectional study assessed the predictors of smoking in a cohort of male students in 3 universities in Saudi Arabia. A pre-tested, validated questionnaire was used to determine sociodemographic characteristics, academic performance, peers' smoking, and presence of a smoker within the family. Of the 337 participants, 30.9% were current smokers (smoked 1 or more cigarettes within the last 30 days). Lower academic performance (OR = 2.29, 95% CI: 1.02-5.17), peer smoking (OR = 4.14, 95% CI: 1.53-11.3) and presence of other smokers in the family (OR = 2.77, 95% CI: 1.37-5.64) were the significant predictors of smoking status identified using multiple logistic regression analysis. These findings highlight the influence of family and peer pressure in initiating cigarette use among the youth of Saudi Arabia. PMID:24673080

    Infidelity appears to be a common phenomenon. Although there are initially positive consequences for the unfaithful partner, it has negative impacts on individuals, the relationship and health in the long-term. How often are extradyadic sexual contacts indicated within a German sample? Which factors predict infidelity? Via Internet (n=1 899) socio-demographic, individual (attitudes towards infidelity, religiosity), relationship (global and emotional relationship satisfaction, length of primary relationship, sexual agreements), and contextual factors (opportunities) were surveyed. The results of the regression analysis on an 80% subsample (n=1 533) were cross-validated with the remaining 20% of the data (n=366). The analysis showed that 4% of lesbian women, 34% of gay men, 29% of heterosexual women and 49% of heterosexual men reported extra-dyadic sexual contacts. Sexual orientation and restrictive attitudes towards monogamy and infidelity were found to be significant predictors. Low global relationship satisfaction, longer duration of primary relationship, non-monogamous relationships, availability of alternative sexual partners and ways to conceal infidelity increased the likelihood of extradyadic involvement. Cross-validation with 20% of the data (n=366) confirmed the stability of the regression model. Future research should examine identified predictors using representative population-based data. Predictors should be considered in therapy. PMID:25494186

    Full Text Available Introduction: Quality of life among patients with epilepsy is severely affected by consequences of physical, psychological, social of epilepsy. The aim of present study was to evaluate predictors of quality of life in epileptic patients and to determine the main effective factors. Methods: This is a comparative cross sectional study on 100 epileptic patients and 100 healthy people from patient's relatives who referred to neurology clinic of 22 Bahman hospital in Mashhad. Data were collected through the WHO quality of life (QOL standard questionnaire. Multiple linear regression analysis was used to determine predictor factors of quality of life in patients with epilepsy. Results: The mean total score of quality of life in two groups of patients and healthy people showed no significant difference. Only in the physical (P<0.001, environment (P=0.002 and social domain (P<0.001 differences were statistically significant. Multiple linear regression analysis showed that age, sex, education level, type of epilepsy, and numbers of seizures in one month are effective factors. In all four domains of QOL, quality of life score decreased by increasing the episodes of seizures. Moreover, females compared with males had higher quality of life scores. Conclusion: Age, sex, education level, type of epilepsy, and number of seizures were important predictors of total QOL in patients with epilepsy. Number of seizures and female gender had higher effect on QOL. Based on our findings controlling numbers of seizures is the key factor in improving the quality of life among patients with epilepsy.

    Due to its peculiar geographical and morphological characteristics, Lake Como (Northern Italy) represents an interesting study-case for investigating the sub-basin scale circulation of persistent organic pollutants (POPs) that, despite being banned since the 1970s, have reached surprisingly high concentrations in some southern alpine lakes as a consequence of their release from melting glaciers in recent years. In particular, the Como Bay, which is located in the city of Como, seems noteworthy because its waters have a longer residence time than the other areas of the lake. The analyses of the historical concentration of PCBs, pp′DDT and its metabolites in a sediment core sampled from the Como Bay covering a time-period from their ban to recent times, showed that the DDTs have never experienced a significant (p PCB metabolite hexa-CB (449.7 ng g(-1) w.w. and 1672.1 ng g(-1) w.w. respectively). The DDT concentrations in the agone (sampled during the years 2006–2009) never exceeded the limits for human consumption in Italy, while concentrations of six selected PCBs exceeded human health advisory recommendations in one of the fish samples analysed, when it was approximately two times higher than the recommended value of 125 ng g(-1) w.w.

    Full Text Available OBJETIVO: Os sintomas da dermatomiosite (DM podem ser um indício da existência de um câncer oculto. Melhorar a detecção precoce é essencial, porém não há estudos avaliando em curto prazo os fatores preditivos para a doença. MÉTODO: Estudo retrospectivo, monocêntrico, incluindo pacientes com DM definida (pelo menos quatro dos cinco critérios de Bohan e Peter, 1975, no período entre 1991 e 2011. A presença de malignidade foi limitada a um período de até 12 meses após o diagnóstico da doença. RESULTADOS: Houve 12 casos de neoplasias em 139 pacientes (pele, trato gastrintestinal, próstata, tireoide, mama, pulmão e trato geniturinário. Os pacientes com neoplasia tiveram maior média de idade que os controles (56,8 ± 15,7 vs. 40,3 ± 13,1 anos, respectivamente, P = 0,004; odds ratio 1,09; intervalo de confiança de 95%: 1,04-1,14. Não foram observadas diferenças estatísticas em relação a gênero, etnia, frequência de sintomas constitucionais, envolvimento de órgãos e sistemas e/ou alterações laboratoriais. CONCLUSÃO: Na DM recém-diagnosticada, a idade tardia ao diagnóstico foi um fator preditivo de malignidade.OBJECTIVE: Dermatomyositis (DM symptoms may be a clue to the existence of a hidden cancer.

    Full Text Available Background: Cardiac output (CO measurement is not a standard of care for critically ill children, but it can be estimated by indirect methods such as veno-arterial pCO2 difference (ΔVACO2. Aim: To determine the correlation between CO and ΔVACO2 and evaluate the usefulness of ΔVACO2 in the diagnosis of low CO in an experimental pediatric model. Materials and Methods: Thirty piglets weighing 4.8 ± 0.35 kg were anesthetized and monitored with transpulmonary thermodilution. Lung injury was induced with tracheal instillation of Tween 20®. Serial measurements of central venous and arterial blood gases, as well as CO, were obtained at baseline, 1, 2 and 4 h after lung injury induction. Low cardiac output (LCO was defined as CO lower than 2.5 Llminlm². Results: There was an inverse correlation between CO and ΔVACO2 (r = -0.36, p < 0.01. ΔVACO2 was 14 ± 8 mmHg in LCO state and 8 ± 6 mmHg when this condition was not present (p < 0.01. Area under the receiver operating characteristic (ROC curves of ΔVACO2 and LCO state was 0.78 (0.68-0.86. The best cut-point was 8.9 mmHg to determine LCO with a sensibility 0.78, specificity 0.7, positive predictive value 0.27 and negative predictive value 0.96. Conclusions: In this model there was an inverse correlation between ΔVACO2 and CO. The best cutoff value to discard LCO was ΔVACO2 of 8.9 mmHg, indicating that under this value the presence of LCO is very unlikely.

    El artículo examina el estatuto epistemológico de la bioética como disciplina académica. El autor sostiene que el estatuto epistemológico de un discurso lo determina la pregunta fundamental que se plantea y la respuesta que se busca, focos integradores del discurso. En el caso de la bioética, la pregunta fundamental es de índole moral. La bioética es pues una disciplina ética que tiene su hogar epistemológico en la filosofía. El autor también defiende el concepto de “éticas aplicadas”. Sugiere finalmente que el método de la bioética, sobre todo la que se hace desde nuestras latitudes, debería adoptar el círculo hermenéutico como metodología para su filosofar. PMID:20463860

    Full Text Available En el marco de la investigación CONDES Imaginarios posibles en la Arquitectura se propuso, como ejercicio de diseño arquitectónico, la realización de proyectos a partir de una reflexión teórico-crítica sobre el carácter neobarroco de la contemporaneidad. El objetivo fue explorar una poética semiótica generadora de los instrumentos que nos permitiera concebir lo neobarroco como estrategia proyectual. El objeto arquitectónico a proyectar debía imaginarse como un conjunto de formas, contenidos y dinámicas capaces de proponer una estrategia comunicativa al usuario, determinadas por una estética barroca. El presente trabajo expone las interconexiones que esta experiencia ha revelado entre los conceptos formales propuestos por Omar Calabrese en su teoría La era neobarroca y la realidad socio-cultural presente en Maracaibo. La obra arquitectónica se reconoce parte de unos procesos que conciernen al conjunto de los mensajes que circulan en el territorio de la comunicación y que quedan a interpretación de la comunidad.

    2014-06-01

    Full Text Available El desarrollo de la marcha infantil es un proceso especialmente complejo en que el intervienen factores motores, perceptivos y cognitivos. Desde el nacimiento, el niño integra la información recibida y realiza un progresivo control cortical sobre los patrones neuromotores innatos para desarrollar diferentes formas de locomoción hasta la marcha independiente. Estas ideas no son novedosas pero se están revisando en la actualidad y han motivado numerosos cambios en el estudio del desarrollo infantil. La consideración de la adquisición de la marcha como un aprendizaje en situaciones de constante cambio permite comprender la marcha como acción, cuya realización implica la adquisición de nuevas capacidades de interacción y conocimientos. En este trabajo se exponen los principales conocimientos acerca de este proceso de aprendizaje y se propone destacar las alteraciones de la marcha como indicadores de dificultades en el desarrollo, que requieren una valoración y un abordaje terapéutico interdisciplinares.

    2012-03-01

    Full Text Available O texto pretende argumentar que o cenário dominante de “crise da política” nas sociedades modernas reflete um complexo processo de reconfiguração da vida social e do modo como se vive. Mediante diálogo crítico com alguns representantes da sociologia política da modernidade radicalizada, procura agregar elementos para que se perceba que o atual fracasso da política é o fracasso de um modo de fazer e de pensar a política, herdeiro direto do “capitalismo histórico”. Não é o fracasso da política como tal, mas de uma modalidade de política, de sistema político, de prática política. Deve ser associado a uma espécie de fadiga do material de que foi forjada a política moderna, que sempre esteve referenciada por Estados nacionais e constitucionais fortes, por partidos de massas e parlamentos ativos, bem como pelo funcionamento eficaz de regimes de democracia representativa.

  15. La seducción como estética

    Directory of Open Access Journals (Sweden)

    Claudia Barrera

    2012-09-01

    Full Text Available La seducción es tratada desde la literatura, la sociología, la psicología y la política como una estrategia de manipulación. Sin embargo, si se la estudia desde el campo filosófico y su tradición estética vemos sus poderes constructores de una sensibilidad poética por las fuerzas atractivas y repulsivas que contiene. La seducción, como fuerza e impulso, se inscribe en un movimiento en que el aparecer de la realidad, la imaginación y, desde luego, el arte —fuente de emotividad y sensaciones— permiten valorarla. La estética de la seducción se despliega desde la subjetividad y no desde los contenidos de la filosofía del arte. Su capacidad relacional y sus poderes condensados en el espíritu del hombre no pueden pertenecer al aparato instrumental de la sociedad de consumo o las estrategias de manipulación donde ha sido estigmatizada. Por esto la seducción es presentada como fuente de deseo y potencia vital.

  17. Modeling Natural Stream Nutrient Concentrations from Landscape Predictors

    Olson, J. R.; Hawkins, C. P.

    2012-12-01

    Understanding how much land use change has affected nutrient concentrations in aquatic ecosystems requires a way of estimating the nutrient concentrations that were present in these systems before they were altered. Pre-alteration data are generally not available, but models that associate natural landscape variation with stream nutrient concentrations can be used to predict natural nutrient concentrations. These models can also provide insight into which processes are primarily responsible for observed natural spatial and temporal variability in stream nutrient concentrations. We used data from 782 reference sites across the western USA to develop empirical models that predict natural, base-flow concentrations of total phosphorus (TP) and total nitrogen (TN). Models were built using Random Forests, a nonparametric regression technique that accounts for both interactions between variables and non-linear relationships. We developed candidate predictor variables associated with nutrient sources, sinks, or other processes potentially affecting nutrient concentrations among sites. Factors associated with watershed geology and P availability were the most important predictors of TP. Climate and co-precipitates were less important predictors. TN concentrations were equally associated with climate, atmospheric deposition, and vegetation phenology. Both models were relatively accurate (Root Mean Squared Errors independent validation sites) and made better predictions than previous models of natural nutrient concentrations. However, the models were not very precise (r2 = 0.46 for the TP model, and r2 = 0.23 for the TN model). An analysis of the sources of variation showed that our models accounted for a majority of the spatial variation in nutrient concentrations, and much of the imprecision was due to temporal or measurement variation in nutrient concentrations.

    Fever is a common complaint in infancy, and bacteraemia is one of the more serious causes of such fever. However, there exists scanty data on risk of bacteraemia among febrile infants of developing countries and what clinical predictors, if any, could identify those febrile infants with bacteraemia. To address this issue, 102 infants aged 1-12 month(s) attending the Children's Emergency Ward of University College Hospital, Ibadan, Nigeria, with rectal temperatures of > or = 38 degrees C and with a negative history of antimicrobial use for at least one week prior to presentation, were studied to identify clinical predictors of bacteraemia. Infants, meeting the eligibility criteria of the study, underwent a full clinical evaluation and had blood cultures done for aerobic organisms by standard methods. Over 38% of the infants had bacteraemia. Escherichia coli (35.9%), Staphylococcus aureus (33.3%), and Klebsiella spp. (10.3%) of positive cultures were commonly isolated. Three variables, age of 15,000/mm3, were significant independent predictors of bacteraemia. Each of these variables was associated with a 3-6-fold increase in risk of bacteraemia (age of 15,000/mm3: odds ratio 5.4, p = 0.024). The variables, in combination, correctly classified 70% of the infants into 'bacteraemia' or 'no bacteraemia'. It is concluded that; in the setting of the study, about 4 in 10 febrile infants would have a positive blood culture for aerobic organisms and that age of or = 15,000/mm3 are associated with a significantly increased risk of bacteraemia. Clinicians practising in such a setting need to be aware of the increased risk of bacteraemia in infants with these clinical features. PMID:12430758

    Background: In some patients with chest pain, selective coronary angiography reveals slow contrast agent passage through the epicardial coronary arteries in the absence of stenosis. This phenomenon has been designated the slow coronary flow (SCF) phenomenon. Objectives: In this study, we aimed to describe the demographic and clinical findings and presence of common atherosclerosis risk factors in patients with the SCF phenomenon. Patients and Methods: Between October 2014 and March 2015, demographic data, clinical histories, atherosclerosis risk factors, and laboratory and angiographic findings were recorded for all consecutive patients scheduled for coronary angiography and diagnosed with the SCF phenomenon, as well as a control group (patients with normal epicardial coronary arteries; NECA). SCF was diagnosed based on the thrombolysis in myocardial infarction frame count (TFC). A TFC > 27 indicated a diagnosis of SCF phenomenon. Results: Among the 3600 patients scheduled for selective coronary angiography, 75 (2%) met the SCF criteria. SCF and NECA patients did not exhibit statistically significant differences in traditional risk factors except for hypertension, which was more prevalent in SCF than NECA patients (52% versus 31%, P = 0.008). A multivariable analysis indicated a low body mass index, presence of hypertension, low high-density lipoprotein cholesterol (HDL-c) level, and high hemoglobin level as independent predictors of the SCF phenomenon; of these, hypertension was the strongest predictor (odds ratio = 6.3, 95% confidence interval: 2.2 - 17.9, P = 0.001). Conclusions: The SCF phenomenon is relatively frequent, particularly among patients with acute coronary syndrome who are scheduled for coronary angiography. Hypertension, a low HDL-c level, and high hemoglobin level can be considered independent predictors of this phenomenon. PMID:26889458

    To date, little is known about enduring clinical distress as measured with the commonly used distress thermometer. We therefore used the distress thermometer to examine: (a) the prevalence of enduring clinical distress, distress-related problems, and subsequent wish for referral of women with breast cancer, and (b) sociodemographic, clinical, and psychosocial predictors of enduring clinical distress. The study had a multicenter, prospective, observational design. Patients with primary breast cancer completed a questionnaire at 6 and 15 months postdiagnosis. Medical data were retrieved from chart reviews. Enduring clinical distress was defined as heightened distress levels over time. The prevalence of enduring clinical distress, problems, and wish for referral was examined with descriptive analyses. Associations between predictors and enduring clinical distress were examined with multivariate analyses. One hundred sixty-four of 746 patients (22 %) reported having enduring clinical distress at 6 and 15 months postdiagnosis. Of these, 10 % wanted to be referred for care. Fatigue was the most frequently reported problem by patients with and without clinical distress, at both time points. Lack of muscle strength (OR = 1.82, 95 % CI 1.12-2.98), experience of a low level of life satisfaction (OR = 0.77, 95 % CI 0.67-0.89), more frequent cancer worry (OR = 1.40, 95 % CI 1.05-1.89), and neuroticism (OR = 1.09, 95 % CI 1.00-1.18) were predictors of enduring clinical distress. In conclusion, one in five women with breast cancer develops enduring clinical distress. Oncologists, nurse practitioners, and cancer nurses are advised to use single-item questions about distress and distress-related problems to ensure timely detection of high-risk patients. Providers should also routinely assess fatigue and its causes, as fatigue is the most frequently reported distress-related problem over time. PMID:27417105
