O casal na perspectiva relacional-simbólica e a qualidade conjugal : uma análise conceptual e metodológica

Este trabalho aborda o casal de dois ângulos diferentes, o da Perspectiva Relacional- Simbólica e o dos estudos da Qualidade Conjugal, tendo como objectivos o confronto de conceitos apresentados nas duas formas de estudo, compreender de que forma se aproximam ou não, fazer uma reflexão crítica dos estudos da Qualidade Conjugal e apresentar o instrumento Entrevista Clínica Generacional, com potencial para ultrapassar grande parte dos problemas apontados aos estudos da Qualidade Conjugal. Conclui-se que a metodologia dos estudos da Qualidade Conjugal não se adequa ao estudo da família porque não têm em conta a relacionalidade, nem a forma como os cônjuges se influenciam mutuamente, nem as dinâmicas do casal, não permitindo a compreensão do casal na sua totalidade. Conclui-se que o instrumento apresentado tem respostas a vários problemas identificados, nomeadamente no que diz respeito à metodologia, na forma como leva a que o estudo seja efectivamente da família e não relacionado com a família e na questão da relacionalidade da família. Além disso, permite aceder a níveis de informação que os estudos da Qualidade Conjugal não conseguiram, nomeadamente a história progressiva e expectativas inconscientes, bem como levar a que o casal se confronte e possa fazer descobertas recíprocas.This work approaches the couple from the Relational-Symbolic Perspective and the Marital Quality studies angle, having as objectives to confront the concepts presented in both kinds of research, to understand if the concepts used are similar in each research kind, to critically reflect uppon Marital Quality research and to present the instrument “Entrevista Clínica Generacional”, that has the potential to overcome the majority of problems pointed out to Marital Quality Research. It is concluded that Marital Quality research methodology is not suitable to family studies as they don’t consider the couple’s relational nature, nor the way spouses mutually influence, nor couples dynamics, which does not allow to understand the couple completely. It is concluded that the presented instrument has solutions to many of the identified problems, such as methodology issues, its capability to allow the research to be, indeed, family research instead of family related studies and the relational issues. Besides, it allows to access levels of information that the Marital Quality research doesn’t, namelly the couple’s progressive history and unconscious expectations, as well as it allows the spouses to confront themselves and make reciprocal discoveries

The situation of women in BRIC countries: a comparative analysis of the (in) effectiveness of public policies for the protection of women and reduction of gender inequality in the four largest emerging economies in the world

The research consists of a comparative study of the concrete experiences of Russia, China, India and Brazil on the implementation of policies for the protection of women and reduction of gender inequality. From a constitutional perspective of analysis, it seeks to overcome the purely nomological or doctrinal comparison, typical of the classical view of Comparative Law, in favor of an experiences and realities comparison. To achieve this goal, it uses a complex set of data gathered from relevant reports on the subject in the international context, as well as, realizing a explorative study of the existing literature on the subject in each of the countries. As main results, it was verified that the four countries suffer from serious problems regarding the effectiveness of gender equality and the guarantee of women’s dignity, freedom, and respect. However, each country faces specific challenges in dealing with the issue

E-mentoring entre Professores e Alunos na EaD: um Estudo de Caso na Graduação em Administração de uma Instituição Pública Federal

Busca-se neste trabalho sobre Educação a Distância compreender como se configuram as relações de e-mentoring entre professores e alunos no curso de graduação em Administração a distância oferecido por uma instituição pública federal brasileira. Como arcabouço teórico aborda-se o conceito de mentoria, suas características, funções e fases. Aborda-se ainda e-mentoring e Educação a Distância com suas características e relações. Realizou-se um estudo de caso; as técnicas de coleta foram entrevistas online com professores/alunos, observação não participante e análise documental, estudando-se os dados por meio de análise de conteúdo. Os resultados indicam que as relações de mentoria estabelecidas entre tutores e alunos configuram-se como e-mentoring, já que os tutores são mais acessíveis aos alunos e mantêm uma comunicação mais frequente, tanto por meio de diversas ferramentas de comunicação quanto por meio de encontros presenciais, além de fornecer apoio profissional e pessoal aos alunos. Já a relação estabelecida entre professores e alunos se configura como um outro tipo de relação, que não é de mentoria, pois as características não se enquadram nos conceitos desse construto.Palavras-chave: Educação, Educação a Distância (EAD), Ensino superior, Mentoria, E-mentoring. E-mentoring among Professors and Students on E-learning: This Case Study is about a Degree Course of Business Administration at Public InstitutionAbstractIn this research about e-learning, we try to understand how the e-mentoring relationship among Tutors and Students works in a Business Administration course offered at distance by a public Brazilian institution. As theoretical approaches, it is observed the concept of mentoring, its features, functions and phases. It also covers e-mentoring and distance education with its characteristics and relationships. A case study was made, the data collection techniques were an online interview with tutors/students, non-participative observation and documental analysis on content analysis theory. The results demonstrate that the mentoring relationship between Tutors and Students can be defined as e-mentoring: they are accessible to the students and keep intense communication on face-to-face meetings and also by the online tools provided on the course platform. On the other hand, the relationship established by Tutors and Students cannot be defined by e-mentoring due to lack of connections on the e-learning concepts.Keywords: Education, E-learning, Graduation degree, Mentoring, E-mentoring

Motor Programs as Indicators of Penalty Direction in Soccer

Introduction: Many football games are decided on penalties and usually in championship final games. When seeking to anticipate movements, differences in amplitude can harm players because the informational movement appears to be spread "globally" throughout the action and should be coded at several levels. Thus, it would be interesting to analyze the entire period of the kick, since the player begins his run to approach the ball to recognize the motor patterns used in the kick that identify his direction. Objective: The objective of this study is to identify patterns of behavior in penalty kicks that may indicate the direction of their action / kick and in my moment they appear. Methodology: The sample consisted of 21 subjects hitting a penalty kick, 18 males and 3 females with an average age of 22.18 ± 2.44 years and two goalkeepers with college football experience. The tests consisted of a battery of two penalty kicks for each subject in order to score. The kicks were recorded by a video camera with a front view of the goal goal and the back of the batter. The kick phases were divided into the starting leg position; first step leg; angle of the elbow in relation to the body seen from behind; angle of the elbow in relation to the displacement line seen from above; direction of the tip of the supporting foot and position on the goal where the kick was. Each kick was preceded by a start signal. The data were analyzed from the registration of each variable and the position of the goal in which the ball was kicked, considering it in three sectors: left, right and central. Results: The main results indicated that the variable “Leg of the first step” had 81% of the kicks associated with the direction of the goal; 52.4% of second kicks had repeated the pattern of behavior and 84.6% had repeated the pattern of behavior regardless of the goal position. The variable “Elbow angle in relation to the body seen from behind” had 81.8% repeated behavior pattern regardless of the goal position and the variable “Elbow angle in relation to the displacement line seen from above” had 81% association with the sector of the goal in which the ball was kicked; 52.4% of second kicks had repeated the pattern of behavior and 91.7% had repeated the pattern of behavior regardless of the goal position. Conclusions: The main conclusions indicate that it is possible to relate the kick location with the batter\u27s body information; the start of the race seems to indicate that there is a prior intention of movement programs; the decision of where to hit the penalty appears to be made before contact with the ball and more closely to the placement of the support foot and with this relationship, the size of the goal to be defended by the goalkeeper could be reduced, increasing the possibility of defense

Application of edible coatings in conservation of acerola

The acerola is a tropical fruit recognized for its high nutritional value, however, the high pereceability after harvest motivated by its climacteric behavior requires conservation techniques that allow the maintenance of its quality during the storage period. The edible coatings, in this context, are presented as alternatives since they form barriers on the fruits, restricting the gas exchanges, improving the visual aspect without compromising with the fruit flavor. Thus, this study aims to evaluate the application of edible coatings on the post-harvest quality of acerolas cv. Costa Rica during refrigerated storage (10 °C). Fruits of ripe acerolas were harvested in a commercial orchard, sanitized and immersed in three solutions (3%) of cassava starch, arrow starch and gelatine, in addition to the control represented by uncoated fruits for a period of 3 minutes. These were then dried and packed in styrofoam polystyrene trays coated with polypropylene plastic film (PVC) and stored under refrigeration (10 °C) for 12 days. The total fresh solids content (º Brix), titratable acidity (% malic acid), pH, TSS/AT ratio and sensorial analysis on the occurrence of wilting were evaluated every three days, visual appearance and the aroma of the fruits. The experimental design was completely randomized in a factorial scheme of 4x5, that is to say, (4 treatments: control, cassava starch, arrowroot starch and gelatin) and (5 storage times: 0, 3, 6, 9 and 12 days ), with five replicates and the experimental plot composed of 100 g trays. During the storage period, no significant difference was observed between the coatings used, however, their action on the fruits contributes to reduce the loss of fresh mass and to allow a better balance in the fruit flavor ratio (SST / AT) after 12 days . The films formed on the fruits did not compromise the chemical quality (soluble solids, titratable acidity and pH) maintaining similar behavior to the fruits of the control treatment. In addition, there was a reduction in the incidence of wilting and the loss of the characteristic aroma of the fruits, contributing to a better visual appearance. Thus, edible coatings based on cassava starch and arrowroot and gelatine are presented as effective alternatives in preserving the quality of acerolas during refrigerated storage.La acerola es una fruta tropical reconocida por su alto valor nutricional, sin embargo, la alta perecedera después de la cosecha motivada por su comportamiento climático requiere técnicas de conservación que permitan mantener su calidad durante el período de almacenamiento. Los recubrimientos comestibles, en este contexto, se presentan como alternativas ya que forman barreras en las frutas que restringen el intercambio de gases, mejorando el aspecto visual sin comprometer el sabor de la fruta. Por lo tanto, este estudio tiene como objetivo evaluar la aplicación de recubrimientos comestibles en la calidad poscosecha de acerola cv. Costa Rica durante el almacenamiento refrigerado (10 °C). Las frutas maduras de acerola fueran cosechadas en un huerto comercial, fueran desinfectadas y sumergidas en tres soluciones de recubrimiento (3%) con almidón de yuca, almidón de araruta (arrurruz) y gelatina, además del control de frutas sin recubrimiento durante un período de 3 minutos. Luego se secaron y se colocaron en bandejas de isopor de poliestireno forradas con película de plástico de polipropileno (PVC) y se almacenaron en un refrigerador (10 ºC) durante 12 días. Cada tres días se evaluó la pérdida de masa fresca (%), el contenido total de sólidos solubles (º Brix), la acidez titulable (% de ácido málico), el pH, la relación SST / TA y el análisis sensorial en la aparición de marchitez, aspecto visual y aroma de las frutas. El diseño experimental fue completamente al azar en un esquema factorial 4x5, es decir (4 tratamientos: control, almidón de yuca, almidón de arrurruz y gelatina) y (5 tiempos de almacenamiento: 0, 3, 6, 9 y 12 días), con cinco repeticiones y la porción experimental compuesta de bandejas de 100 g. Durante el período de almacenamiento no hubo diferencias significativas entre los recubrimientos utilizados, sin embargo, su acción sobre las frutas contribuye a reducir la pérdida de masa fresca y permite un mejor equilibrio en la relación de sabor de la fruta (SST / TA) después de 12 días. Las películas formadas en las frutas no comprometieron la calidad química (sólidos solubles, acidez titulable y pH) manteniendo un comportamiento similar a las frutas del tratamiento de control. Además, hubo una reducción en la incidencia de marchitamiento y la pérdida del aroma característico de la fruta, lo que contribuyó a una mejor apariencia visual. Por lo tanto, los almidones de yuca comestibles y los recubrimientos de arrurruz y gelatina son una alternativa efectiva para preservar la calidad de la acerola durante el almacenamiento en frío.A acerola é um fruto tropical reconhecido por seu elevado valor nutricional, contudo, a alta perecebilidade após a colheita motivada por seu comportamento climatérico requer técnicas de conservação que permitam a manutenção de sua qualidade durante o período de armazenamento. Os revestimentos comestíveis, nesse contexto, apresentam-se como alternativas uma vez que formam barreiras sobre os frutos restringindo as trocas gasosas, melhorando o aspecto visual sem comprometimento com o sabor dos frutos. Assim, este estudo tem por objetivo avaliar a aplicação de revestimentos comestíveis sobre a qualidade pós-colheita de acerolas cv. Costa Rica durante o armazenamento refrigerado (10 ºC). Frutos de acerolas maduras foram colhidos em pomar comercial, sanitizados e imersos em três soluções (3%) de revestimento com amido de mandioca, amido de araruta e gelatina, além do controle representado pelos frutos sem revestimento por um período de 3 minutos. Em seguida, estes foram secos e acondicionados em bandejas de isopor de poliestireno revestidas com filme plástico de polipropileno (PVC) e armazenados em refrigerador (10 ºC) por 12 dias. A cada três dias foram avaliados a perda de massa fresca (%), conteúdo de sólidos solúveis totais (º Brix), acidez titulável (% ácido málico), pH, relação de SST/AT além de análise sensorial sobre a ocorrência de murchamento, aparência visual e o aroma dos frutos. O delineamento experimental adotado foi o inteiramente casualizado em esquema fatorial de 4x5, isto é, (4 tratamentos: controle, fécula de mandioca, fécula de araruta e gelatina) e (5 tempos de armazenamento: 0, 3, 6, 9 e 12 dias), com cinco repetições e a parcela experimental composta por bandejas de 100 g. Ao longo do período de armazenamento não houve diferença significativa entre os revestimentos utilizados, todavia, sua ação sobre os frutos contribui para reduzir a perda de massa fresca  e possibilitar um melhor balanço na relação de sabor  dos frutos (SST/AT) após 12 dias. As películas formadas sobre os frutos não comprometeram a qualidade química (sólidos solúveis, acidez titulável e pH) mantendo comportamento semelhante aos frutos do tratamento controle. Além disso, houve redução na incidência de murchamento e na perda do aroma característico dos frutos contribuindo para uma melhor aparência visual. Dessa forma, os revestimentos comestíveis a base de amido de mandioca e araruta e gelatina apresentam-se como alternativas eficazes na preservação da qualidade de acerolas durante o armazenamento refrigerado

Differential tolerance of sugarcane varieties to herbicide stress

Este trabalho foi desenvolvido com o objetivo de realizar triagem primária para caracterização da tolerância de variedades SP e CTC de cana-de-açúcar à aplicação de dez herbicidas comumente recomendados para manejo de plantas daninhas nesta cultura. Dois experimentos foram desenvolvidos com esquema fatorial entre variedades de cana-de-açúcar e onze tratamentos herbicidas. No primeiro experimento utilizaram-se sete variedades SP (fatorial 7 x 11): SP80-1842, SP80-3280, SP83-2847, SP87-344, SP87-396, SP89-1115 e SP90-3414. No segundo experimento, foram avaliadas seis variedades CTC (fatorial 6 x 11): CTC1, CTC2, CTC3, CTC4, CTC5 e CTC6. Os tratamentos herbicidas aplicados em pós-emergência inicial foram: ametryn, ametryn + trifloxysulfuron-sodium, clomazone, diuron + hexazinone, isoxaflutole, imazapic, 2,4-D, tebuthiuron, sulfentrazone, MSMA e testemunha sem aplicação. Avaliou-se massa fresca, altura, teor de clorofila (índice SPAD) e perfilhamento, todos em termos percentuais relativos à testemunha sem aplicação. Constatou-se tolerância diferencial das variedades de cana-de-açúcar aos herbicidas comumente utilizados na cultura. As variedades SP80-3280 e CTC2 foram as mais tolerantes aos tratamentos herbicidas, podendo ter esta característica explorada em programas de melhoramento genético.This work was carried out with the objective of screening for tolerance response of SP and CTC sugarcane varieties to application of ten herbicides commonly recommended to weed management in this crop. Two trials were evaluated with factorial design between the sugarcane varieties and eleven herbicide treatments. In the first experiment, seven SP varieties were used (factorial 7 x 11): SP80-1842, SP80-3280, SP83-2847, SP87-344, SP87-396, SP89-1115 and SP90-3414. In the second experiment, six CTC varieties were evaluated (factorial 6 x 11): CTC1, CTC2, CTC3, CTC4, CTC5 and CTC6. The post-emergence-applied herbicide treatments were: ametryn, ametryn + trifloxysulfuron-sodium, clomazone, diuron + hexazinone, isoxaflutole, imazapic, 2,4-D, tebuthiuron, sulfentrazone, MSMA and check without application. The variables evaluated were: fresh mass, height, SPAD index and tillering: Valves here considered as relative percentage to the untreated control. Differential tolerance of sugarcane varieties was observed regarding to application of the tested herbicides. SP80-3280 and CTC2 were the most tolerant varieties to herbicide application, and might have this characteristic exploited by sugarcane breeding programs.FAPES

Reaction of passion fruit genotypes to Cowpea aphid-borne mosaic virus (CABMV)

O endurecimento dos frutos causado pelo vírus Cowpea aphid-borne mosaic virus (CABMV) é considerada a virose economicamente mais importante no maracujazeiro-azedo (Passiflora edulis f. flavicarpa Deg.). Com o objetivo de avaliar a reação de genótipos de maracujazeiro-azedo ao vírus do endurecimento do fruto implantou-se em casa-de-vegetação na Estação Biológica da Universidade de Brasília (UnB) um experimento utilizando-se mudas provenientes de sementes. O delineamento experimental utilizado foi de blocos inteiramente casualizados com quatro repetições e 4 plantas por parcela, testando-se 62 genótipos. A inoculação do vírus foi feita mecanicamente utilizando-se o extrato obtido a partir de material foliar sintomático em solução tampão fosfato de sódio e o abrasivo “celite”, em folhas de mudas com 150 dias de idade. Foram realizadas duas avaliações em intervalos de 15 dias. A avaliação da severidade do CABMV foi feita através de uma escala de notas de 1 a 3, sendo 1 folhas sem sintomas de mosaico; 2 folhas com mosaico leve e sem deformações foliares; 3 folhas com mosaico severo, com bolhas e deformações foliares. Na segunda avaliação, os genótipos MAR 20#35, MAR 20#11, MAR 20#51, MAR 20#32 e MAR 20#44 apresentaram a maior porcentagem de plantas resistentes (88%, 87%, 81%, 75%, 73%, respectivamente) e os genótipos MAR 20#09, MAR 20#49, MAR 20#02, MAR 20#27, MAR 20#62, MAR 20#50 e MAR 20#15 apresentaram a menor porcentagem de plantas resistentes (19%, 19%, 13%, 13%, 13%, 7% e 6%, respectivamente). Foram selecionadas plantas resistentes, para posterior inoculação e seleção, dando-se continuidade ao programa de melhoramento genético. ____________________________________________________________________________________ ABSTRACTThe disease caused by Cowpea aphid-borne mosaic virus (CABMV) is considered the economically most important viruses in Passionfruit (Passiflora edulis f. flavicarpa Deg.). In order to investigate the reaction of Passionfruit genotypes to CABMV, an experiment was carried out in glasshouse conditions at the experimental station of Brasilia University. The experimental design was randomized blocks with four replications and six plants per plot. A number of 62 genotypes were tested. The plants were mechanically inoculated using an extract obtained from a symptomatic leaf material in a solution of sodium phosphate and an abrasive named “celite”, in leaves of seedling with 150 days of age. Two evaluations have been done, at 15 days interval. The score were done using a lesion scale graded from 1 to 3, where 1 means no disease, 2 leafs with mild mosaic and no leaf deformation, and 3 leafs with severe mosaic, blisters and leaf deformations. The genotypes MAR 20#35, MAR 20#11, MAR 20#51, MAR 20#32 e MAR 20#44 showed the higher percentage of resistant plants (88%, 87%, 81%, 75%, 73%, respectively) and the genotypes MAR 20#09, MAR 20#49, MAR 20#02, MAR 20#27, MAR 20#62, MAR 20#50 e MAR 20#15 showed the lower percentage of resistant plants (19%, 19%, 13%, 13%, 13%, 7% e 6%, respectively), in the second evaluation. The progenies with the highest level of resistance were chosen for future inoculation and for future selection, continuing genetic improvement program
