    The thematic network ‘Biodiversity of Insects in the Amazon’ is the first network among researchers of the Brazilian Amazon in terms of the increase of knowledge and provision of subsidies for the conservation of Amazonian biodiversity, focusing on insects, and disseminate this knowledge to different sectors of society. In this way, expeditions to six localities in the Amazonas State were carried out and we present here the results for social wasps (Vespidae: Polistinae). We used two modified Malaise traps combined with two suspended traps from July 2016 to June 2017. A total of 140 species and 20 genera were collected: 92 species and 18 genera in ZF-2-Manaus area, where the greatest diversity was recorded, followed by Tefé (73 species, 16 genera), Careiro-Castanho (72 species, 17 genera), Novo Airão (71 species, 16 genera), Presidente Figueiredo (62 species, 16 genera), and Ipixuna (58 species, 17 genera). Metapolybia rufata Richards, 1978 and Polybia diguetana du Buysson, 1905 were new records for Brazil, and other six species were first records for Amazonas state. The results indicate that further investigations should significantly increase the species diversity of wasps in the Amazon region and add more information to the knowledge of Polistinae diversity

    The aim of this study was two-fold: (a) to describe the in-season variations of training monotony, training strain, and acute: chronic workload ratio (ACWR) through session rated perceived exertion (s-RPE), total distance and high-speed running (HSR); (b) to compare those variations between starters and non-starters. Seventeen professional players from an European First League team participated in this study. They were divided in two groups: starters (n=9) and non-starters (n=8). The players were monitored daily over a 41-week period of competition where 52 matches occurred during the 2015- 2016 in-season. Through the collection of s-RPE, total distance and HSR, training monotony, training strain and ACWR were calculated for each measure, respectively. Data were analysed across ten mesocycles (M: 1 to 10). Results revealed no differences between starters vs non-starters (p>0.05). M6 had a greater number of matches and displayed higher values in monotony (s-RPE, total distance and HSR), strain (only for total distance) and ACWR (s-RPE, TD and HSR). However, the variation patterns for all indexes displayed some differences. In conclusion, the values of both starters and non starters showed small differences between them and thus suggesting that the adjustments of training workloads that had been applied over the season helped to reduce differences according to the player status. Even so, there some variations over the season (microcycles and mesocycles) for the whole team. This study could be used as reference for future coaches, staff and scientists.info:eu-repo/semantics/publishedVersio

    PROCESSO DECISÓRIO, RENTABILIDADE E RISCOS NA RELAÇÃO ENTRE USINAS SUCROENERGÉTICAS E PROPRIETÁRIOS RURAIS DE DOURADOS – MS

    O presente estudo analisou a tomada de decisão diante da rentabilidade e os riscos que os proprietários rurais de Dourados - MS poderá obter junto às usinas sucroenergéticas por meio do arrendamento, fornecimento ou parceria agrícola. Para isso, utilizaram-se os fundamentos da Nova Economia Institucional com foco na Economia dos Custos de Transação e do Processo Decisório com foco na Racionalidade Limitada. O estudo foi realizado a partir de informações bibliográficas, documentais e utilização de entrevistas junto às usinas sucroenergéticas e proprietários rurais, tendo como base o processo decisório a partir da rentabilidade e dos riscos da utilização das propriedades rurais na produção de cana-de-açúcar para as usinas. Por meio dos resultados conclui-se que o processo decisório dos proprietários é fragmentado, devido ao baixo conhecimento sobre a produção de cana-de-açúcar no local. Os proprietários rurais aguardam a consolidação do setor sucroenergético no município, ingressando no setor apenas com arrendamento e parceria agrícola minoritário, no qual a rentabilidade é maior que a da atividade tradicional e o risco é baixo na comparação com a modalidade de fornecimento de cana-de-açúcar.&nbsp

    Fuga mundi na relação entre igreja e mundo:

    Get PDF
    Ao longo da história do cristianismo, a fuga mundi surgiu como forma radical de vivência cristã. Esse modo de viver os valores do Evangelho correspondeu a necessidades específicas do contexto do seu surgimento. No entanto, com o passar do tempo, alguns princípios norteadores da fuga mundi colaboraram para a implantação, em larga escala no cristianismo, de uma compreensão de mundo dualista que separa a Igreja do mundo, bem como faz oposição entre corpo e alma, sagrado e profano, matéria e espírito. Entretanto, a Igreja está inserida no mundo, da mesma maneira como “o Verbo de Deus se fez carne e habitou entre nós” (Jo 1,14). A reflexão realizada pelo Concílio Vaticano II, expressa na Gaudium et spes, fornece elementos relevantes para essa evangélica autocompreensão da Igreja no mundo. Há outros autores que também refletiram sobre as relações entre cristianismo e mundo como, por exemplo, o teólogo luterano Dietrich Bonhoeffer (1906-1945). Neste artigo, faz-se uma crítica à atitude de fuga mundi, a partir da análise comparativa de alguns escritos de Bonhoeffer e da Gaudium et spes, o que permite compreender melhor o modo dialógico e servidor de existir das igrejas cristãs no mundo contemporâneo (chamado por Bonhoeffer de “mundo adulto”). Ao mesmo tempo, reflete-se sobre a superação dos dualismos e sobre a delimitação do lugar que a fuga mundi teve na Igreja Católica, a partir do evento conciliar

    In-season internal load and wellness variations in professional women soccer players: comparisons between playing positions and status

    The internal intensity monitoring in soccer has been used more in recent years in men's football, however, in women's soccer, the existing literature is still scarce. The aims of this study were threefold: (a) to describe the weekly variations of training monotony (Foster, 1998), training strain and acute:chronic workload ratio (Murray et al., 2017) through session Rated Perceived Exertion (s-RPE); (b) to describe weekly variations of Hooper Index [stress, fatigue, Delayed Onset Muscle Soreness (DOMS) and sleep] (Hooper & Mackinnon, 1995); and (c) to compare those variations between playing positions and player status. Nineteen players (24.1±2.7 years) from a Portuguese BPI League professional team participated in this study. All variables were collected in a 10-week in-season period with 3 training sessions and 1 match per week during the 2019/20 season. Considering the overall team, the results showed that there were some associations between Hooper Index categories and s-RPE like stress or fatigue (0.693, p<0.01), stress or DOMS (0.593, p<0.01), stress or s-RPE (-0.516, p<0.05) and fatigue or DOMS (0.688, p<0.01). There were no differences between all parameters in playing positions or player status. In conclusion, the study revealed that higher levels of fatigue and DOMS occurs concurrently with better nights of sleep. Moreover, any in-season variations concerning internal load and perceived wellness seems independent of position or status in outfield players. Also, the data showed that the higher the players’ reported stress, the lower the observed s-RPE, thus possible indicating a mutual interference of experienced stress levels on the assimilation of training intensity by women elite soccer players.info:eu-repo/semantics/publishedVersio

    This study aimed to estimate the prevalence of impact of oral health conditions on physical and psychosocial dimensions among adolescents and to identify factors associated with severity of impact. The impact of oral health status was assessed by the instrument Oral Health Impact Profile (OHIP-14). The covariates were: socioeconomic status, habits and health care, use of dental services, and normative conditions of oral health. Structural equation modeling was performed, and 15.6% of adolescents reported impact in at least one dimension of the OHIP-14. The dimensions that showed the highest prevalence of impact were psychological distress (11.8%) and physical pain (6.6%). The number of teeth needing dental treatment, number of filled teeth, and CPI significantly affected severity of impact. In this adolescent population, unfavorable socioeconomic conditions were associated with reduced use of dental services, associated in turn with precarious oral health conditions and increased severity of impact.El objetivo de este estudio fue evaluar el impacto de las condiciones de salud bucal en sus dimensiones físicas y psicosociales entre adolescentes. La gravedad del impacto fue tratada como variable latente, medida por medio de un cuestionario Oral Health Impact Profile (OHIP-14). Las covariables fueron: el nivel socioeconómico, los hábitos y el cuidado de la salud, utilización de servicios dentales y condiciones de salud bucal. Se realizó un modelado de ecuaciones estructurales y los modelos fueron estimados por máxima verosimilitud. El efecto del número de dientes con necesidad de tratamiento, número de dientes restaurados y el CPI de la gravedad del impacto fue significativo. En esta población, las condiciones socioeconómicas desfavorables se asocian con una menor frecuencia de uso de los servicios dentales, que están asociadas con malas condiciones de salud oral, y que a su vez se correlacionaban con una mayor gravedad del impacto.O objetivo deste estudo foi estimar a prevalência do impacto das condições de saúde bucal nas suas dimensões física e psicossocial entre adolescentes, bem como identificar os fatores associados à gravidade do impacto.
