The human face is an array of variable physical features that together make each of us unique and distinguishable. Striking familial facial similarities underscore a genetic component, but little is known of the genes that underlie facial shape differences. Numerous studies have estimated facial shape heritability using various methods. Here, we used advanced three-dimensional imaging technology and quantitative human genetics analysis to estimate narrow-sense heritability, heritability explained by common genetic variation, and pairwise genetic correlations of 38 measures of facial shape and size in normal African Bantu children from Tanzania. Specifically, we fit a linear mixed model of genetic relatedness between close and distant relatives to jointly estimate variance components that correspond to heritability explained by genome-wide common genetic variation and variance explained by uncaptured genetic variation, the sum representing total narrow-sense heritability. Our significant estimates for narrow-sense heritability of specific facial traits range from 28 to 67%, with horizontal measures being slightly more heritable than vertical or depth measures. Furthermore, for over half of facial traits, >90% of narrow-sense heritability can be explained by common genetic variation. We also find high absolute genetic correlation between most traits, indicating large overlap in underlying genetic loci. Not surprisingly, traits measured in the same physical orientation (i.e., both horizontal or both vertical) have high positive genetic correlations, whereas traits in opposite orientations have high negative correlations. The complex genetic architecture of facial shape informs our understanding of the intricate relationships among different facial features as well as overall facial development.
Statistical Methods for Identifying Sequence Motifs Affecting Point Mutations
Authors: Zhu Yicheng , Neeman Teresa , Yap Von Bing , Huttley Gavin A
Published: December 2016

Mutation processes differ between types of point mutation, genomic locations, cells, and biological species. For some point mutations, specific neighboring bases are known to be mechanistically influential. Beyond these cases, numerous questions remain unresolved, including: what are the sequence motifs that affect point mutations? How large are the motifs? Are they strand symmetric? And, do they vary between samples? We present new log-linear models that allow explicit examination of these questions, along with sequence logo style visualization to enable identifying specific motifs. We demonstrate the performance of these methods by analyzing mutation processes in human germline and malignant melanoma. We recapitulate the known CpG effect, and identify novel motifs, including a highly significant motif associated with A→G mutations. We show that major effects of neighbors on germline mutation lie within ±2 of the mutating base. Models are also presented for contrasting the entire mutation spectra (the distribution of the different point mutations). We show the spectra vary significantly between autosomes and X-chromosome, with a difference in T→C transition dominating. Analyses of malignant melanoma confirmed reported characteristic features of this cancer, including statistically significant strand asymmetry, and markedly different neighboring influences. The methods we present are made freely available as a Python library https://bitbucket.org/pycogent3/mutationmotif.
The influence of external factors on the accuracy of non-invasive measuring of oxygen in blood
Authors: Snizhko Y. M. , Sarana V. M.
Published: December 2016

In this paper we investigated a pulse oximetry-based method for mobile devices. This method obtains bio-signals related to blood pulsation in transparent parts of body. The most widely accepted field for use of this method is hospital care. In these cases a pulse oximeter is the best solution for the monitoring of emergency patients. A promising field for pulse oximetry is physical exercise. It only requires simple clips such as ear-clips, finger-clips, headbands etc. However this method presents some difficulties: weak signal, noise ratio, motion artefacts, low perfusion. We used a MAX30100 Oximeter and Heart Rate Sensor integrated circuit to obtain signals of blood pulse waves from red and infrared light emission diodes (LED). This device measures the oxygen saturation of a person’s blood by placing an LED and a photodetector against the thin skin of a person’s body, such as a fingertip, wrist or earlobe. The MAX30100 is a 14-pin surface mount integrated circuit that contains sensors for measuring a person’s heart rate. It can also indirectly determine the oxygen saturation of a person’s blood. The MAX30100 provides a complete pulse oximetry and heart rate measurement solution for medical monitors and wearable fitness devices. As each LED emits light into a person’s finger, the integrated photodetector measures variations in light caused by changes in blood volume. An integrated 16-bit analog to digital converter (ADC) with programmable sample rate converts the photodetector output to a digital value. The MAX30100 filters out ambient light that can interfere with an accurate reading. Data are read through a serial I2C interface to computer for further processing. The LED current can be programmed from 0 to 50 mA with proper supply voltage. The LED pulse width can be programmed from 200 µs to 1.6 ms to optimize measurement accuracy and power consumption based on use cases. The SpO2 algorithm is relatively insensitive to the wavelength of the infrared LED, but the red LED’s wavelength is critical to correct interpretation of the data. The temperature sensor data can be used to compensate errors with ambient temperature changes. During the experiments we registered oxygen concentration values under different conditions. With low muscular activity we observed high stability and repeatability of measuring values under various exterior conditions. However, with high muscular activity there were various artefacts in the gauged signals that led to contortion of effects. We identified the boundaries of the validity of measuring and propose the use of an adapted filter in order to distinguish pulse waves from optical signals more reliably. These devices can be applied in fitness training , medical monitoring and used as wearable devices.
Influence of the liposomal preparation Butaintervite on protein synthesis function in the livers of rats under the influence of carbon tetrachloride poisoning
Authors: Hariv M. I. , Gutyj B. V.
Published: December 2016

This article presents the results of research into the influence of the complex liposomal preparation Butaintervit on protein synthesis function in the livers of rats under the influence of carbon tetrachloride poisoning. Intramuscular injection of carbon tetrachloride into rats at a dose of 0.25 ml per100 gof body weight causes antigenic load on the body and leads to disruption of protein synthesis function in the liver. This is shown by reduction in blood levels of total protein and its fractions. Thus, the level of albumin in the serum of rats under the conditions of oxidative stress was 70% lower than in clinically healthy animals. However, the level of total protein in the serum was only 10% lower. This is because, along with the decrease of albumin content in the serum, the levels of globulin protein fraction increased by 8.8%. This has led to albumin/globulin disparities in the serum of sick animals. As a result, the value of A/G coefficient was 0.28 ± 0.03, compared to 0.52 ±0.02 inclinically healthy rats. For the normalization of functional state of the liver under oxidative stress it is advisable to apply the liposomal preparation Butaintervite, which in its structure contains butafosfan, interferon, thistle and vitamins A, D and E. Under conditions of oxidative stress and under the action of the liposomal preparation in the rats from the second experimental group we have found significant increase in the levels of total protein and albumins and a decrease in serum globulin in the animals on the fifth and tenth days of the experiment. On the fourteenth day of the experiment under the conditions of oxidative stress and under the action of the liposomal preparation in the rats from the second experimental group the normalization of protein synthesis function in the liver was observed. The level of indicators of total protein, albumin, globulin and the coefficient of albumin/globulin compared with the control group of animals were within normal values.
Validación y aplicación de un modelo de restauración de manglar basado en individuos para tres especies en la Ciénaga Grande de Santa Marta
Authors: Rodríguez-Rodríguez Jenny Alexandra , Mancera-Pineda José Ernesto , Rodríguez-P. Juan Manuel
Published: December 2016

En la década de los años 90 los manglares de la Ciénaga Grande de Santa Marta (CGSM) murieron masivamente por los altos niveles de salinidad en el suelo. Este hecho estimuló la reapertura de cinco canales naturales para reducir la salinidad y mejorar las condiciones del bosque (Proyecto PROCIENAGA). Con base en esta experiencia, en 1999 un modelo basado en individuos (FORMAN) fue desarrollado para simular trayectorias de restauración del bosque; sin embargo, este modelo fue restringido a un único sitio de la CGSM y a la fecha no había sido probado. Para mejorar su sensibilidad y predictibilidad para simular tendencias del Área Basal (AB) de los árboles de Rhizophora mangle, Avicennia germinans y Laguncularia racemosa en este estudio se validó, calibró y ajustó el modelo FORMAN, usando datos de 16 años de monitoreo. Para ello, se modificó la interfaz del modelo y se ajustaron algunas rutinas de cálculo y parámetros. Se ejecutaron dos escenarios de simulación: (1) Asumiendo estabilidad en el intervalo de variación de la salinidad y, (2) aumentado la salinidad de acuerdo con el incremento promedio de los últimos tres años. Los ajustes en las tasas de reclutamiento y salinidad calculada permitieron calibrar el modelo y reproducir el patrón y la magnitud observada en tres estaciones. En dos estaciones solo se reprodujo el patrón de los datos. Las tendencias generales del AB de cada especie y su dinámica, así como las magnitudes actuales para las estaciones que sufrieron mayor impacto inicialmente, fueron reproducidas adecuadamente. Bajo un escenario en el que la salinidad se mantiene en un intervalo estable, el sistema alcanzaría la estabilidad en el largo plazo (>100 años). Un incremento promedio constante en la salinidad intersticial, resultaría en una disminución severa del AB en el corto plazo (menos de 20 años), demostrando la vulnerabilidad de la CGSM a los incrementos en salinidad y la necesidad de implementar medidas de manejo sostenibles en el tiempo. El estudio contribuye al entendimiento de la dinámica de lagunas costeras tropicales en el largo plazo y resalta la importancia de la modelación como herramienta básica para los proyectos de rehabilitación y manejo.
Effects of scaffolded intensive reading on students’ reading comprehension performance
Authors: Sevilla Morales Henry
Published: December 2016

This research sought to explore the connection between a small-group intensive reading comprehension project and students’ performance in two sample English national exit exams (ENEEs) developed by the Ministry of Public Education, Costa Rica. The data were gathered from an intervention plan that combined the theoretical principles of schema theory, scaffolded reading comprehension, and intensive reading. The study adopts an action-research approach and uses a mixed design that combines quantitative and qualitative data in the analysis and interpretation of results. Participants included twelve students from a public high school in the Western Area of Costa Rica who needed special preparation for the ENEE, which narrows the research scope down to this population only. The data collection techniques included two sample ENEEs, field notes, and research artifacts. Findings reveal positive effects of scaffolded reading comprehension on student ENEE performance, but also it is warning that the generalizations to larger populations is not possible. The study sets implications at theoretical and practical level, and it calls for further investigation as a way to tackle the limitations identified.
Tamaño de la muestra en modelos de ecuaciones estructurales con constructos latentes: Un método práctico
Authors: Vargas Halabí Tomas , Mora-Esquivel Ronald
Published: December 2016

La técnica de modelaje mediante ecuaciones estructurales resulta muy útil para investigadores educativos para trabajar diversos constructos latentes, en forma simultánea, y someter a prueba modelos que clarifiquen diferentes tipos de efectos. Empero, la literatura aún no ha brindado una respuesta adecuada en lo referente al tamaño de muestra procedente para utilizar dicha técnica. Asimismo, a pesar de que existe una diversidad de criterios para su estimación, aún no ha proporcionado un método práctico que permita compendiarlos y facilitar la argumentación del tamaño apropiado de esta. Por ello, el presente artículo tiene como objetivo ofrecer una guía práctica a investigadores educativos para utilizar la diversidad de criterios y justificar el cálculo apropiado del tamaño de muestra en ecuaciones estructurales, mediante la planificación a priori de modelos de medida y modelos estructurales. Se recurre a un método cuantitativo para determinar los insumos con base en diagramas de sendero de modelos a priori de una investigación, así como interfaces disponibles en internet para calcular los tamaños de muestra. Los datos se resumen en forma tabulada para efectos comparativos. La aplicación del método constata su utilidad para que el investigador defina un umbral de casos que permita satisfacer distintos criterios, con respecto a depender de una única regla o criterio para justificar el tamaño de la muestra apropiado. Asimismo, revela la ventaja que podría representar el uso de parcelas en la planificación a priori de modelos con esta técnica

Authors: Ardón Esquivel Diana , Leytón Vega Febel , Méndez Rodríguez Nandy , Monge Brenes Katherine , Valverde Cabezas Gloriana
Published: December 2016

Este artículo científico presenta los resultados de una investigación realizada del 2013 al 2015, cuyo principal objetivo consistió en analizar cómo se lleva a cabo la pedagogía hospitalaria en Costa Rica, específicamente con la niñez menor de siete años. Para esto, se utilizó una metodología cualitativa y descriptiva, la recolección de datos se realizó por medio de observaciones, cuestionarios y entrevistas; la información obtenida se registró en instrumentos elaborados por las investigadoras. En este estudio, se tomaron en cuenta dos hospitales del país (institución A e institución B), que brindan servicio educativo a población infantil. El estudio concluye que en la institución A se brinda propiamente un servicio de pedagogía hospitalaria, el currículo está adaptado a la condición de salud de la niñez; además es flexible y dinámico. En la institución B, el currículo más bien está orientado al desarrollo de las competencias de lenguaje en los niños y las niñas, y basa su labor en un programa del SELC (Servicio de Estimulación del Lenguaje y la Comunicación) que está en proceso de estudio. Se concluye que en el país no existe un marco legal específico que respalde la labor de la pedagogía hospitalaria. Se recomienda que a nivel nacional se desarrolle legislación específica que apoye la pedagogía hospitalaria y que esta se extienda a mayor cantidad de hospitales, también, por parte las universidades, se brinde formación a los docentes con respecto a la modalidad educativa en específico.

Published: December 2016

El presente artículo propone un modelo de capital intelectual para la investigación en universidades públicas de la Costa Caribe colombiana. Para tal efecto, se realizó un estudio cuantitativo y de tipo analítico situacional con una población de siete (7) universidades conformada por 290 personas y una muestra de 79 sujetos informantes líderes de grupos de investigación categorizados y avalados por cada universidad objeto de estudio, a los cuales se les aplicó un cuestionario tipo Likert de 57 ítems. El análisis e interpretación de los datos permitió caracterizar en las universidades públicas de la Costa Caribe colombiana los activos intangibles presentes de forma favorable en los componentes de capital intelectual. Así como también, la presencia de los enfoques estratégico-corporativo y social evolutivo para la generación de capital intelectual desde la investigación. Lo anterior fue tomado como base para estructurar el modelo propuesto a partir de la presencia de treinta y cuatro variables o tipos de activos intangibles agrupados en once elementos o grupos de activos intangibles que forman parte del capital humano; el capital digital; el capital relacional formado por el capital social y el capital negocio; el capital estructural formado por el capital organizativo y el capital tecnológico.
Capacidad de una medida de inflación percibida para predecir el índice de confianza del consumidor, las expectativas de inflación y la inflación en costa rica, 2006-2012
Authors: Agüero-Morera Diego , Bien-Briceño Andrés , Villalobos-Delgado Mauricio
Published: December 2016

En este estudio se construyó el Índice de Precios Percibidos al Comprador (IPPC) para estimar la inflación percibida en Costa Rica de julio 2006 a diciembre 2012. Con base en los fundamentos teóricos de Brachinger (2006,2008), se modificó la metodología del índice de Precios del Consumidor (IPC), dándole un mayor peso a los bienes de la canasta que se compran con más frecuencia. Se utilizó el IPPC para estimar modelos ARMA y ARDL, donde se evidenció una buena capacidad de pronóstico para el IPC de estratos bajos y las expectativas de inflación. Al comparar el IPC y el IPPC, la diferencia relativa entre los dos índices tiende a ser superior para niveles más altos de inflación, siendo mayor el índice propuesto. Además, artículos comprados semanalmente como la gasolina, el casado y el transporte en taxi predominan en la media de la variación interanual mensual del IPPC; mientras que el peso de bienes comprados semestral o anualmente es prácticamente nulo.
Adam Smith’s concept of labour: value or measure?
Authors: Rodríguez Herrera Adolfo
Published: December 2016

Smith is considered the father of the labour theory of value developed by David Ricardo and Karl Marx and simultaneously of the cost-of-production theory of value developed by John Stuart Mill and Alfred Marshall. This polysemy is partly because Smith is developping the terminology to refer to value and measure of value, and often uses it with much imprecision. That has led to different interpretations about his position on these issues, most of them derived from an error of interpretation of Ricardo and Marx.

This paper reviews the concepts developed by Smith to formulate his theory of value (value, real price and exchangeable value). Our interpretation of his texts on value does not coincide with what has traditionally been done. According to our interpretation, it would not be correct the criticism made by Ricardo and Marx on Smith’s position about the role of labour as measure of value. For these authors, Smith is not consistent in proposing that the value of a commodity is defined or measured as the amount of labour necessary to produce it and simultaneously as the amount of labour that can be purchased by this commodity. We try to show that for Smith the labour has a double role –as source and measure of value–, and that to it is due the confusion that generates his use of some terms: Smith proposes labour as a measure of value because he conceives it as a source of value. With this interpretation it becomes clear, paradoxically, that Smith holds a labour theory of value that substantially corresponds to the one later developed by Ricardo and Marx.
Masonería en tiempos electorales: El fenómeno del Bronco y la antimasonería en Nuevo León, México (2015)
Authors: Tzili Apango Eduardo
Published: December 2016

En las elecciones estatales de 2015 en México, Jaime Rodríguez Calderón “el Bronco” sorprendió a la opinión pública al ganar la elección para gobernador de Nuevo León. En vísperas de finalizar el periodo de campaña, surgieron videos en YouTube señalando al “Bronco” como masón, adjudicándole toda una serie de mensajes religiosos, morales, políticos y sociales. Este artículo analiza los videos en el contexto de las percepciones sobre la masonería en México. Llego a la conclusión de que, debido al significado social e históricamente construido sobre la masonería en México, ha surgido una tendencia política y electoral antimasónica, con el fin de influir la intención del voto y manipular las percepciones sociales.

A Seuso-kincs Meleagros-táljának képprogramja
Authors: Gesztelyi Tamás
Published: December 2016

A Seuso-kincs Meleagros-tálján összesen nyolc szerelmi történet különíthető el, közülük négy esetében a vadászatnak is fontos szerep jut. Az ábrázolt történetek fő szólama tehát a mindenen felülkerekedő szerelem, az emberi életet mozgató legfontosabb érzelem. A történetek mellékszólama a vadászat, melyet konkrétan és átvitt értelemben egyaránt értelmezhetünk. Arisztokratikus kedvtelés, de egyúttal az erények gyakorlása is, melyben akár a női nem is részesülhet, lásd Helené vagy Atalanté jelenetét. Bár a szerelmi motívum szerepeltetésének magyarázatára nem kell feltétlenül aktuális alkalmat keresnünk, mégis csábító a gondolat, hogy a kincs korabeli funkcióját nászajándékban határozzuk meg. Hajlunk tehát arra a magyarázatra, hogy a kincs jómódú tulajdonosa, Seuso valamikor az V. század elején nászajándékba kapta ezt az egyedülálló asztali ezüstkészletet.

Szent Elek életének leírása a középkor egyik legismertebb és több nyelvre lefordított legendája. Jelen tanulmányban a legenda eredetét, a különböző nyelvű változatok jellegét (szír, görög, latin és népnyelvű változatok) és egyedi sajátosságait, valamint a magyar nyelvű hagyományt tárgyalom. Kutatásom során mindenekelőtt a legenda népszerűségére kerestem a választ, amely valószínűleg leginkább a változatok közös motívumkincsében és annak értelmezésében rejlik, amelynek bővülése és változása a legkorábbi szír változatoktól egészen a legelső népnyelvű változatokig megfigyelhető.

ABSTRACT Objective Verifying the psychometrics of a Brazilian version of the Dispositional Resilience Scale (DRS-15). Methods Cross-cultural adaptation was done interviewing 65 adult patients. Validation was evaluated by application of the Lipp Brazilian Stress Symptoms Inventory (ISSL), Self-Report Questionnaire (SRQ), and other measures to 575 participants from the psychiatric ambulatories (for borderline personality, anxiety or post-traumatic stress disorders) and non-psychiatric ambulatories (chronic pain, pre-anesthetic consultation and companions for the latter). Temporal stability was verified with 123 participants. Results Exploratory factor analysis yielded a three-factor solution. Psychometrics were acceptable (alpha coefficient, 0.71; intraclass correlation coefficient, 0.81). Correlations with the ISSL, SRQ and other measures were noted except for factor 3. In the psychiatric sample, hardiness scores of borderline patients were lower than those of patients with anxiety disorders. Conclusion This version of the DRS-15 exhibited good reliability in a sample of Brazilian patients; validity was confirmed in two of the scale factors.

Published: December 2016

ABSTRACT Multiple sclerosis (MS) may present with a cognitive impairment as disabling as the physical disabilities. Therefore, routine cognitive evaluation is pivotal. Valid and reliable neuropsychological tests are essential in follow-up and to define future therapeutic interventions. Objectives To investigate the correlation between the disabilities of MS patients and their cognitive impairment assessed by the Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS). Methods Forty patients with definitive diagnoses of MS were selected. The correlation coefficient (r) between the Expanded Disability Status Scale (EDSS) and the neuropsychological tests of BICAMS were calculated. Results The correlation was clinically substantial and significant with r = 0.55 (p < 0.01) in the Symbol Digit Modalities Test (SDMT), 0.54 (p < 0.01) in the Brief Visuospacial Memory Test (BVMT) and 0.40 (p < 0.05) in the California Verbal Learning Test (CVLT). Conclusion BICAMS has easy and satisfactory application and evaluation for routine visits and presents a significant correlation with the EDSS. Its use may be indicated for screening and monitoring of cognitive impairment in patients with MS.

Published: December 2016

ABSTRACT Multiple sclerosis (MS) is a chronic neuroimmunological disease that mainly affects young adults, leading to neurological disabilities over the course of their lives. Many psychiatric conditions have been reported in patients with MS, but there are remarkably few studies assessing empathy among these patients. Methods This is a single center, cross-sectional study, of 34 patients with MS and 34 matched control subjects. A specific questionnaire (empathy quotient) was used. Results Patients with MS showed significantly lower levels of empathy. This finding was not correlated with disease duration, degree of disability, drugs for treating MS or lesion load on resonance magnetic imaging. Conclusion Decreased empathy is a frequent condition in patients with MS and should be addressed in order to diminish the psychosocial burden of this neurological disease.
INFLUENCE OF DIFFERENT TEMPERATURE LEVELS ON THE DATE OF FULL BLOOM OF PEACH VARIETIES IN SUBTROPICAL CLIMATE

Published: December 2016

ABSTRACT The dormancy dynamics of temperate fruit tree species is complex and highly variable according to genotype and environment. Due to this variability, many phenological models of cold units have not been suitable for subtropical climatic conditions in southern Brazil. The aim of this study was to evaluate the influence of air temperature on the peach dormancy in Urussanga-SC. For this purpose, the correlations between the date of full bloom of sixteen peach varieties and the total hours in which the temperatures remain in certain thermal levels were evaluated. Two groups of varieties with highly differentiated responses to temperature in various times were identified. In the first group, consisting of ten varieties, the beginning of significant influence (p<0.05) of temperatures on the date of full bloom occurred as earlier, in February. In this group, temperatures between 16 and 22 °C accumulated from March to June were those that most contributed to the flowering advance. In the second group, the beginning of the significant influence of temperatures occurred later in April. In this group, the accumulated high temperatures from early April to late May anticipated the full bloom, but from May 25, temperatures below 10 °C were responsible for this advance. This behavior differs from traditional phenological models that consider a sequential cold and heat requirement in the resting phase. The results obtained indicate the possibility of an alternating or parallel influence of different temperature levels on dormancy.

ABSTRACT Queen palm is a tropical species of ecological importance and economic potential in various uses, including food. However, the knowledge about the nutritional value of fruits and the estimation of seed viability are still scarce. The aims of this work were to study the biometrics and chemical composition of fruits and seeds; describe the anatomy of embryos and assess the viability of the tetrazolium test. Mature fruits were collected, processed and submitted to biometry, water content, pulp and seeds chemical composition, germination and emergence in the laboratory evaluations. For the tetrazolium test, whole embryos were immersed in solution at 40 °C for one, two, four and six hours and compared with germination. The fruit pulp is rich in carbohydrates. The tetrazolium test performed at 40 ° C and 0.2% solution for two hours is adequate to estimate seed viability.

Published: December 2016

ABSTRACT The economic and scientific interest in Hancornia speciosa (mangabeira) has been growing in recent years, mainly due to the marketing of fruit and extraction of natural compounds with high pharmacological potential. In this study, a scientometric survey about mangabeira was carried out in order to promote and direct future studies on the species. As a result, low scientific productivity associated with this species was found, with only 131 articles published in the last 69 years. In addition, this study identified some trends in bibliographic production on mangabeira, among them: the increasing number of articles over the years; scientific dissemination in nationwide journals; the main focus of this study is associated with agronomic studies; the experimental approach is more frequent and usually associated with populations of restricted geographical distribution; and the scientific production is mainly from education institutions. Furthermore, this study also allowed the identification of some gaps in knowledge about mangabeira, among them the difficulty in describing and characterizing botanical lines; lack of analysis of the genetic diversity of widely distributed populations; lack of management and conservation projects for the species; lack of description of cultivation, collection and preservation techniques of fruits; and lack of identification of natural compounds responsible for its pharmacological activity. It is expected that the data generated in this study will serve to direct future studies on H. speciosa.
Methodological Criteria for Scoring Clustering and Switching in Verbal Fluency Tasks
Authors: Becker Natália , Salles Jerusa Fumagalli de
Published: December 2016

Abstract The objective of this study was to describe an adaptation to Brazilian Portuguese of the methodological criteria for analysis of clustering and switching in semantic verbal fluency (SVF) and phonemic verbal fluency (PVF) tasks. The adaptation process consisted of six steps, including the selection of the clustering and switching variables based on data from a sample of 419 children and the analysis of inter-rater reliability (six raters). The following variables were scored: the total number of words generated the raw number of clusters, the mean cluster size, and the raw number of switches. There was a significant association between raters (intra-class correlation coefficients between 0.95 and 0.99), showing that the analytical method was reliable. Our study provides an evaluation of SVF and PVF tasks that goes beyond the overall score, making it possible to investigate the cognitive processes underlying this neuropsychological function.

Resumo O estudo objetivou avaliar as evidências de validade de uma versão adaptada para o português do Questionário de Fundamentos Morais que analisa a relevância de cinco fundamentos morais para o julgamento moral: dano/cuidado, justiça/reciprocidade, pertencimento/lealdade, autoridade/respeito e pureza/santidade. Participaram 532 pessoas, considerando-se todas as fases. Os procedimentos incluíram tradução/retradução, análise da adequação nos idiomas inglês e português e análises fatoriais exploratórias. As análises indicaram que uma estrutura de dois fatores foi a melhor solução encontrada. O primeiro fator Individualizante (a = 0,91) e o segundo Coesivo (a = 0,87), solução compatível com a teoria ao agrupar os fundamentos de dano e justiça em contraposição aos demais. Foram encontradas evidências de validade convergente entre os fundamentos de coesão e uma medida de religiosidade. Conclui-se que o instrumento distingue um padrão de escolha moral de individualização ou ligação, o fundamento mais influente e sua estrutura fatorial corrobora àquela dos autores da versão original.

Os resultados indicaram como preditores os conflitos sobre a internet com o pai, a ameaça do conflito interparental, os conflitos sobre internet com a mãe e a prática de apoio emocional paterno. Juntas, essas variáveis explicaram 21,2% da dependência de internet. Os resultados corroboram estudos internacionais e indicam que as variáveis familiares investigadas têm um efeito considerável na predição da DI, tendo em vista que esse é um fenômeno complexo e de natureza multifatorial.

Abstract We examined social class (measured by attendance in public or private schools), gender, and age-related variations in the expression of wishes and gratitude of 430 7- to 14-year-olds (181 male, 62.1% from public schools). Chi-square analysis indicated that students from private schools expressed significantly more social-oriented wishes and connective gratitude, whereas those from public schools expressed significantly more self-oriented wishes. Girls in the public schools expressed significantly more self-oriented wishes and verbal gratitude than did boys. Regression analysis (curve estimation) indicated that verbal gratitude, self- and social oriented wishes increased and concrete gratitude decreased significantly with age, but connective gratitude tended to increase. These findings support the idea that gratitude and wish types involve the development of cognitive aspects, such as taking others into account and thinking about the future, but it is also influenced by the social contexts in which children live, such as their social class.

RESUMO Introdução: Observa-se um pronunciado aumento da popularidade das corridas de rua; consequentemente, há mais adeptos dessa prática. Assim sendo, vários estudos vêm buscando diversas abordagens da modalidade, visando desvendar os mecanismos que a compõem. Objetivo: Verificar a incidência de lesões em praticantes de corrida de rua do município de Criciúma, SC, assim como outros fatores associados, como perfil dos praticantes, características do treinamento e existência de acompanhamento profissional. Métodos: Foi realizado um estudo descritivo transversal com 88 corredores (56 homens e 32 mulheres). Resultados: A média de idade foi 36 anos, sendo que a maioria dos participantes praticava corrida três vezes por semana (55,4%) e, do total da amostra, 43,2% já haviam tido alguma lesão, sendo o joelho (52,6%) o local mais acometido. Entre os que já tinham sofrido lesão, houve forte correlação entre quantidade de lesões e o tempo de prática da modalidade (r = 0,269) e os que percorriam maior distância média diária de treino (r = 0,226). No entanto, os dados demonstraram que o trabalho preventivo não foi eficaz na diminuição de incidência de lesão (r = -0,133). Conclusão: Há uma relação direta entre distância percorrida e lesão, bem como o tempo de prática. A orientação de profissionais não tem influência significativa na redução das lesões, ou seja, muitas lesões podem ser decorrentes do volume e da intensidade dos treinos prescritos ou executados de maneira equivocada, não respeitando o condicionamento físico atual e a individualidade biológica, na perspectiva de superar seus próprios limites de qualquer modo. Ressaltamos a importância de mais estudos que relacionem a progressão de treinamento, lesão e prevenção.

RESUMO Introdução: A deficiência visual é uma limitação sensorial que afeta 6,5 milhões de pessoas somente no Brasil, chegando a 285 milhões no mundo. Os sujeitos afetados pela deficiência visual têm dificuldade maior para manter o equilíbrio, já que a visão é um dos principais sentidos envolvidos nesse complexo processo. Para melhorar essa capacidade físico-motora e, consequentemente, a qualidade de vida desses sujeitos, é necessário aperfeiçoar os outros sistemas de propriocepção. Um dos métodos para isso é o treinamento funcional. Objetivo: Analisar os efeitos do treinamento funcional sobre a propriocepção e o equilíbrio de pessoas com deficiência visual. Métodos: O presente estudo de caso analisou três sujeitos com cegueira total ou baixa visão, durante um programa de treinamento funcional que teve duração de 12 semanas, com duas sessões semanais. O equilíbrio postural foi avaliado em uma plataforma de força, em condição bipodal e olhos vendados. A avaliação da propriocepção de membros superiores foi realizada com um cinesiômetro e a avaliação de membros inferiores foi realizada com a fixação de um flexímetro na articulação do joelho dominante do participante, ambas com os olhos vendados. Os resultados foram analisados de maneira descritiva e utilizando a técnica de análise de séries temporais. Resultados: Todos os sujeitos apresentaram melhora do equilíbrio postural. Com respeito à propriocepção do membro superior, o sujeito 1 (S1) apresentou melhora e quanto à propriocepção do membro inferior todos os sujeitos apresentaram melhora. Conclusão: Dessa forma, os resultados sugerem que o treinamento funcional influenciou positivamente o equilíbrio e a propriocepção desses indivíduos.
Exposition to Factors of the Investment Funds Market in Brazil

ABSTRACT The growth of the investment funds industry in Brazil and its international representativeness indicate the relevance of analyzing this sector. Literature has shown the effects that market factors can have on the performance of investment funds. One way of evaluating the relation between funds' returns and market factors' variations is the return-based style analysis. In this context, this research aimed to investigate, through the style analysis, the exposition to various market factors in two modalities of investment funds. With this analysis, we may infer differences between the allocations and the composition of portfolios, constructing a panorama of sensitivity of funds' returns to the market factors addressed in the study. The database consisted of daily returns of 508 funds, out of which 385 are fixed income funds and 123 are Neutral Long & Short multimarket funds, within the period from January 3, 2005, to July 11, 2014. Through the style analysis, with 6 market factors, we found a difference between the composition of portfolios of multimarket funds and portfolios of fixed income funds. Regarding the evolution of the composition of portfolios in these funds, we observed that the investment style of funds does not seem to be constant over time, something which may be a positive evidence concerning the changes that managers promote in their portfolios, seeking to achieve better profitability indicators.

ABSTRACT: This study aimed to assess the resistance in cowpea cultivars to Bruchidius atrolineatus (Pic) attack. The experiment was conducted at the Faculdade de Ciências Agrárias e Veterinárias of Universidade Estadual Paulista "Júlio de Mesquita Filho" (UNESP), Jaboticabal (SP). The following cultivars were used: BR17 Gurgueia, BR3 Tracuateua, BRS Novaera, Sempre Verde, BRS Milênio, and BRS Urubuquara. The non-preference test without choice evaluated the number of viable eggs, unviable and total posed by insects in grains, after 25 days of confinement. In addition, it was observed, in a daily basis, the total dry matter consumed and dry matter consumed per insect; male and female mass; male, female and total egg-adult cycle length; male and female longevity; sex ratio; number of emerged insects and percentage of emerged insects. The non-preference test with free choice evaluated the number of viable, unviable and total eggs and adult attractiveness after 24 hours and seven days of release. Sempre Verde cultivar was the least preferred for oviposition in the test without choice and showed lower number and percentage of emerged insects. BRS Milênio had the lowest total dry mass consumed and dry mass consumed per insect.

RESUMO: O estudo visou inferir sobre a estabilidade genética, com base na viabilidade polínica, em genótipos de triticale hexaploide utilizados no bloco de cruzamentos do programa de melhoramento genético da Empresa Brasileira de Pesquisa Agropecuária (Embrapa Trigo). O experimento foi conduzido em delineamento inteiramente casualizado. Para cada genótipo, foram avaliadas cinco repetições e cada repetição foi constituída por uma planta. Analisaram-se, por meio de microscopia óptica e pela técnica de Squash com corante carmim acético 1%, 200 grãos de pólen por lâmina, totalizando 1.000 grãos de pólen por genótipo. As variáveis analisadas foram: grãos de pólen binucleados e trinucleados, com pouco amido, vazios, com mais de um poro e de tamanhos diferentes. Os dados obtidos foram submetidos à análise de variância e as médias comparadas pelo teste de Tukey a 1%. Houve diferença significativa entre todas as variáveis. A porcentagem de grãos de pólen binucleados e/ou trinucleados variou de 74 a 97%. Concluiu-se que 66% dos genótipos avaliados apresentaram viabilidade polínica acima de 90%, sendo indicados a continuar fazendo parte do programa de melhoramento genético de triticale, tanto na seleção de parentais como durante os cruzamentos e retrocruzamentos. Portanto, os estudos citogenéticos representam excelente ferramenta de apoio ao melhorista na escolha dos genótipos mais estáveis.

Published: December 2016

RESUMO: O marketing na área de sementes é um instrumento promissor para o aumento da taxa de utilização de sementes certificadas. Objetivou-se no presente trabalho analisar o marketing como ferramenta para promover o aumento da taxa de utilização de sementes certificadas. Vale ressaltar que o não pagamento de royalties com a compra de sementes clandestinas descapitaliza a indústria de sementes e reduz o investimento em novas tecnologias e cultivares pelos setores público e privado, diminuindo consequentemente à probabilidade de sucesso dos agricultores pela utilização de tecnologias ultrapassadas. De maneira geral, verifica-se que o marketing na área de sementes é um importante recurso empregado pelas empresas de sementes, a fim de superar a concorrência e atender às exigências do mercado e, por conseguinte, promover o aumento da taxa de uso de sementes certificadas pelos agricultores.
