Efeito residual do herbicida Kifix® nas culturas de arroz, feijão e sorgo.
As culturas produzidas nos dias atuais necessitam cada vez mais de herbicidas eficazes para o manejo e controle de plantas daninhas nos mais diversos sistemas produtivos integrados. Portanto, torna-se necessário soluções inovadoras que possibilitam o aumento da produtividade com pouco impacto ao agroecossistema. Nesse sentido, este trabalho objetivou determinar o efeito residual do herbicida Kifix® (Imazapir 525 g.kg-1 + Imazapique 175 g.kg-1) em solos de um sistema de integração lavoura pecuária.Apresentação oral - graduação

Teamwork in a coronary care unit: facilitating and hindering aspects
Abstract OBJECTIVE To identify, within a multidisciplinary team, the facilitating and hindering aspects for teamwork in a coronary care unit. METHOD A descriptive study, with qualitative and quantitative data, was carried out in the coronary care unit of a public hospital. The study population consisted of professionals working in the unit for at least one year. Those who were on leave or who were not located were excluded. The critical incident technique was used for data collection, by means of semi-structured interviews. For data analysis, content analysis and the critical incident technique were applied. RESULTS Participants were 45 professionals: 29 nursing professionals; 11 physicians; 4 physical therapists; and 1 psychologist. A total of 49 situations (77.6% with negative references); 385 behaviors (54.2% with positive references); and 182 consequences emerged (71.9% with negative references). Positive references facilitate teamwork, whereas negative references hinder it. A collaborative/communicative interprofessional relationship was evidenced as a facilitator; whereas poor collaboration among agents/inadequate management was a hindering aspect. CONCLUSION Despite the prevalence of negative situations and consequences, the emphasis on positive behaviors reveals the efforts the agents make in order to overcome obstacles and carry out teamwork
Couples that work full time and are happily married : myth or reality?
Este trabalho apresenta parte de uma pesquisa quantitativa cujo principal objetivo foi avaliar a satisfação no casamento de homens e mulheres que optaram por relacionamentos de duplo trabalho. Participaram do estudo 222 homens e 222 mulheres casados/as, funcionários/as em diversas instituições públicas de BrasÃlia - DF. A maior concentração de respondentes de ambos os sexos está na faixa etária entre 31 a 40 anos. Os participantes responderam a um questionário demográfico e à Escala de Ajustamento Diádico - DAS. Os resultados mostraram que a maioria dos participantes está satisfeita com seus relacionamentos, sendo que as mulheres apresentaram média de satisfação inferior à dos homens. Quanto à percepção do futuro do relacionamento, ficou evidente o comprometimento de homens e mulheres em investirem na manutenção do casamento. Os resultados questionam a idéia vigente de falência do casamento e da famÃlia e apontam para uma transformação das relações. _________________________________________________________________________________________________________ ABSTRACTThis paper presents part of a quantitative research regarding marriages in which men and women are engaged in full time work. The main objective was to evaluate marital satisfaction in dual worker couples. Subjects were 222 married men and 222 married women that work in several public institutions in Brasilia - DF. The majority of the participants were between 31 to 40 years old. They answered a demographic questionnaire and the Dyadic Adjustment Scale - DAS. Results showed that the majority of participants were satisfied with their relationships although women presented lower satisfaction scores then men. Regarding the perception of the future of the relationship, the results showed that subjects were committed to preserve their marriage. These data question current ideas that marriages and families are outmoded and point in the direction of a transformation in interpersonal relationships
Efeito de doses e modos de aplicação de calcário em latossolo da Zona da Mata de Rondônia.
O clima em Rondônia é quente, seco de maio a agosto e chuvoso de setembro a abril (mais de 2000 mm no perÃodo chuvoso). Este clima interfere na reatividade e eficiência do calcário, na correção da acidez e fornecimento de cátions básicos para as plantas, pois os solos de Rondônia apresentam diferenças na composição quÃmica, fÃsica, mineralógica e diferenças de manejo. Este trabalho teve por objetivo avaliar a eficiência da calagem aplicada com diferentes doses e modos de incorporação ou mantido em superfÃcie, avaliado pelos Ãndices de acides do solo. O experimento foi conduzido em um Latossolo, com doses de calcário (zero de calcário e doses para elevar a saturação de bases a 50 e 70%) mantido em superfÃcie e incorporado em sistema convencional e mÃnimo de cultivo; foi cultivado soja e após a colheita foi avaliado o pH, Al, Ca+Mg e V%. Os resultados demonstram que não houve interação de respostas devido à s doses de calcário, modos de incorporação ou não, e profundidades de amostragem de solo após quatro meses da calagem; a calagem aumentou o pH do solo, os teores de Ca+Mg e a saturação de bases e diminuiu os teores de Al
Psychopathic Traits of Dutch Adolescents in Residential Care: Identifying Subgroups
The present study examined whether a sample of 214 (52.8% male, M age = 15.76, SD = 1.29) institutionalized adolescents could be classified into subgroups based on psychopathic traits. Confirmatory Factor Analyses revealed a relationship between the subscales of the Youth Psychopathic traits Inventory (YPI) and the three latent constructs of the original model on which it is based. Latent Class Analyses showed that adolescents showing psychopathic traits could be classified into three subgroups. The first group showed low scores on the grandiose/manipulative dimension, the callous/unemotional dimension, and the impulsive/irresponsible dimension (normal group). The second group scored moderate on the grandiose/manipulative dimension and the callous/unemotional dimension and high on the impulsive/irresponsible dimension (impulsive, non-psychopathic-like group). The third group scored high on all three dimensions (psychopathy-like group). The findings revealed that the impulsive, non-psychopathic like group scored significantly higher on internalizing problem behavior compared to the normal group, while the psychopathy-like and the impulsive, non-psychopathic-like group both scored higher on externalizing problem behavior compared to the normal group. Based on a self-report delinquency measure, it appeared that the psychopathy-like group had the highest delinquency rates, except for vandalism. Both the impulsive and psychopathy-like group had the highest scores on the use of soft drugs
