Propiedades Psicométricas de la Escala de Perfeccionismo en el Deporte (PPS-S) para el contexto brasileño.

The objective of this work was to adapt and validate psychometrically the Performance Perfectionism Scale for Sport (PPS-S)for use in the Brazilian population. This instrument was based on the theoretical model of Hewitt and Flett and developed by Hill, Appleton and Mallinson to measure perfectionism in a specific context of sports performance. The validation of the instrument followed the guidelines for transcultural adaptations of health science measurement instruments. After the intercultural adaptation of the original scale in English, the data were collected from 953 athletes (15-16 years old) of both sexes. The original scale model was tested with confirmatory factorial analysis using the LISREL software (version 9.30). The results revealed a satisfactory fit with 3 factors and 9 items (χ2 = 116.15 p <0.001, RMSEA = 0.063, GFI = 0.974, AGFI = 0.961, NFI = 0.937, CFI = 0.928, NNFI = 915, χ2 / gl = 4.83). Satisfactory tests of internal consistency were also generated through the analysis of factorial loads and t-values. In contrast, Cronbach's alpha test scores and composite reliability were not adequate for the latent variable that refers to self-oriented perfectionism. The extracted mean variance lacked a good fit and only assumed convergent validity in one of the three factors of the instrument. Discriminant validity also suggests little conclusive evidence and, therefore, more studies with other samples of athletes are necessary to better evaluate the psychometric properties of the instrument and to assert its adequate use.El objetivo de este trabajo fue adaptarse interculturalmente y examinar las propiedades psicométricas de la Performance Perfectionism Scale for Sport(PPS-S) para uso en la población brasileña. Este instrumento fue basado en el modelo teórico de Hewitt y Flett y desarrollado por Hill, Appleton y Mallinson para medir el perfeccionismo en un contexto específico del desempeño deportivo. La validación del instrumento siguió las directrices para adaptaciones transculturales de instrumentos de medidas en ciencias de la salud. Después de la adaptación cultural de la escala original en inglés, el instrumento fue aplicado en 953 atletas (15-16 años) de ambos sexos. El modelo original de la escala fue probado, con análisis factorial confirmatorio, utilizando el software LISREL (versión 9.30). Los resultados mostraron un ajuste satisfactorio con 3 factores y 9 ítems (χ2 = 116,15 p <0,001, RMSEA = 0,063, GFI = 0,974, AGFI = 0,961, NFI = 0,937, CFI = 0,928, NNFI = 915, χ2 / gl = 4,83). Las pruebas satisfactorias de consistencia interna también se generaron a través del análisis de cargas factoriales y valores t.Contrariamente, los índices de alfa de Cronbach y confiabilidad compuesta no fueron adecuados en la variable latente que se refiere al perfeccionismo auto-orientado. La varianza media extractada carecía de buen ajuste y sólo asumió validez convergente en uno de los tres factores del instrumento.La validez discriminante también sugiere evidencia poco contundente y, por lo tanto, más estudios con otras muestras de atletas son necesarios para evaluar de forma más adecuada las propiedades psicométricas del instrumento y afirmar su uso adecuado

Salicylic acid as a mitigator of water stress in black oats seeds

Oats are a very popular grass used in crop rotation to provide organic matter, green mass and assist in the natural aeration of the soil. Agronomic factors such as acidity correction and soil fertility adjustments can be controlled, but when it comes to climatic factors, cultivation depends on favorable climate conditions for good plant development. For instance, low rainfall occurrences result in decreased percentage of germination and plant development. Water stress affects plant development. Therefore, this study aimed to evaluate the effect of salicylic acid as a water stress mitigator on black oats. The experiment was carried out in the Laboratory of Molecular Biology and Biotechnology of Products and Microorganisms of the University of Parana. Black oats (Avena strigosa Schreb) seeds were submitted to different imbibition treatments: without imbibition, soaked in distilled water, and soaked in salicylic acid. Then, they were placed in gerbox boxes previously moistened with 6000 polyethylene glycol solution with different osmotic potentials (0.0; -0.2; -0.4; -0.6 and -0.8 MPa). The experiment was conducted in a completely randomized design with four replicates. Ten days after the experiment, the following parameters were evaluated: germination percentage, germination velocity index, shoot length and radicle length. Salicylic acid at the concentration used in this study promotes a mitigating effect of water stress caused by PEG6000, increasing the germination percentage of black oat seeds

Basic psychological need satisfaction and thwarting: a study with brazilian professional players of League of Legends

Recently, the skill to play games has led to the professionalization of the activity in the form of “eSports” (electronic sports). Despite the popularity of eSports, little is known about its professional players from a psychological perspective. Given the importance of the coach-created environment in the athletes’ motivational processes, this study aimed to investigate the key psychological dimensions of the coach-created climate in 75 Brazilian professional players of League of Legends (LoL) considering the Self-Determination Theory (SDT) and Achievement Goal Theory (AGT). Fourteen hypotheses were tested, of which seven were confirmed. The empowering climate was a predictor of basic psychological-needs satisfaction and indirectly influenced autonomous motivation. The need satisfaction had a significant impact on both autonomous motivation and on lack of motivation, which, in turn, explained 56% of the variance in well-being and the intention to keep playing eSports. The disempowering climate was a predictor of psychological-needs thwarting but had no significant impact on autonomous motivation or lack of motivation. The results obtained support SDT and AGT in the context of eSports and were similar to those conducted with athletes from traditional sports, indicating that the empower-ing-and-disempowering-coaching-climates conceptualization applies not only to traditional sports athletes but also to professional eSports players.Coordenação de Aperfeiçoamento de Pessoal de Nível Superio

Associação entre fraturas e quedas recorrentes, sintomatologia e orientação em saúde: ossos de vidro

Osteogenesis imperfecta is a rare hereditary disease characterized by a deficiency in the production of type I collagen that interferes with connective tissue, culminating in recurrent fractures with minimal trauma due to bone fragility. In most cases, the disease results from mutations in the COL1A1 and COL1A2 genes, responsible for encoding the type I collagen chain. It is a descriptive study, with a qualitative approach, of the experience report type, with activities developed during the class practice of the subject of Semiology II, in a hospital in the city of Caratinga-MG, portraying the medical care provided to a patient with osteogenesis imperfecta. Thus, the following steps were taken: data collection during anamnesis, physical examination and consultation of medical records. It refers to a male patient, 65 years old, farmer, diagnosed with the disease, hospitalized for a fracture of the right lower limb in the portion of the diaphysis of the femur, totally displaced. In short, the present study aims to contribute to the dissemination of knowledge about osteogenesis imperfecta, given the scarcity of publications and scientific studies on this disease, exploring the clinical and symptomatological history of a patient with osteogenesis imperfecta, highlighting the necessary conducts and guidelines for a good prognosis.A osteogênese imperfeita é uma doença hereditária, rara, caracterizada pela deficiência na produção de colágeno tipo I que interfere no tecido conjuntivo, culminando em fraturas recorrentes a mínimos traumas devido à fragilidade óssea. Na maioria dos casos, a doença resulta de mutações nos genes COL1A1 e COL1A2, responsáveis por codificar a cadeia de colágeno tipo I. Trata-se de um estudo descritivo, de abordagem qualitativa, do tipo relato de experiência, com atividades desenvolvidas durante a aula prática da matéria de Semiologia II, em um hospital da cidade de Caratinga-MG, retratando o atendimento médico prestado a um paciente com osteogênese imperfeita. Atendeu-se assim às etapas: coleta de dados durante anamnese, exame físico e consulta ao prontuário. Refere-se a um paciente sexo masculino, 65 anos, lavrador, com diagnóstico da doença, internado por fratura de membro inferior direito na porção da diáfise do fêmur, totalmente desviada. Em suma, o presente estudo tem como objetivo contribuir na divulgação de conhecimento sobre a osteogênese imperfeita, frente à escassez de publicações e estudos científicos perante tal enfermidade, explorando a história clínica e sintomatológica de um paciente com osteogênese imperfeita, salientando as condutas e orientações necessárias para um bom prognóstico

Geographic patterns of tree dispersal modes in Amazonia and their ecological correlates

Aim: To investigate the geographic patterns and ecological correlates in the geographic distribution of the most common tree dispersal modes in Amazonia (endozoochory, synzoochory, anemochory and hydrochory). We examined if the proportional abundance of these dispersal modes could be explained by the availability of dispersal agents (disperser-availability hypothesis) and/or the availability of resources for constructing zoochorous fruits (resource-availability hypothesis). Time period: Tree-inventory plots established between 1934 and 2019. Major taxa studied: Trees with a diameter at breast height (DBH) ≥ 9.55 cm. Location: Amazonia, here defined as the lowland rain forests of the Amazon River basin and the Guiana Shield. Methods: We assigned dispersal modes to a total of 5433 species and morphospecies within 1877 tree-inventory plots across terra-firme, seasonally flooded, and permanently flooded forests. We investigated geographic patterns in the proportional abundance of dispersal modes. We performed an abundance-weighted mean pairwise distance (MPD) test and fit generalized linear models (GLMs) to explain the geographic distribution of dispersal modes. Results: Anemochory was significantly, positively associated with mean annual wind speed, and hydrochory was significantly higher in flooded forests. Dispersal modes did not consistently show significant associations with the availability of resources for constructing zoochorous fruits. A lower dissimilarity in dispersal modes, resulting from a higher dominance of endozoochory, occurred in terra-firme forests (excluding podzols) compared to flooded forests. Main conclusions: The disperser-availability hypothesis was well supported for abiotic dispersal modes (anemochory and hydrochory). The availability of resources for constructing zoochorous fruits seems an unlikely explanation for the distribution of dispersal modes in Amazonia. The association between frugivores and the proportional abundance of zoochory requires further research, as tree recruitment not only depends on dispersal vectors but also on conditions that favour or limit seedling recruitment across forest types

Mapping density, diversity and species-richness of the Amazon tree flora

Using 2.046 botanically-inventoried tree plots across the largest tropical forest on Earth, we mapped tree species-diversity and tree species-richness at 0.1-degree resolution, and investigated drivers for diversity and richness. Using only location, stratified by forest type, as predictor, our spatial model, to the best of our knowledge, provides the most accurate map of tree diversity in Amazonia to date, explaining approximately 70% of the tree diversity and species-richness. Large soil-forest combinations determine a significant percentage of the variation in tree species-richness and tree alpha-diversity in Amazonian forest-plots. We suggest that the size and fragmentation of these systems drive their large-scale diversity patterns and hence local diversity. A model not using location but cumulative water deficit, tree density, and temperature seasonality explains 47% of the tree species-richness in the terra-firme forest in Amazonia. Over large areas across Amazonia, residuals of this relationship are small and poorly spatially structured, suggesting that much of the residual variation may be local. The Guyana Shield area has consistently negative residuals, showing that this area has lower tree species-richness than expected by our models. We provide extensive plot meta-data, including tree density, tree alpha-diversity and tree species-richness results and gridded maps at 0.1-degree resolution

Digital anamorphosis is used to define a distorted image of health and care that may be viewed correctly using digital tools and strategies. MASK digital anamorphosis represents the process used by MASK to develop the digital transformation of health and care in rhinitis. It strengthens the ARIA change management strategy in the prevention and management of airway disease. The MASK strategy is based on validated digital tools. Using the MASK digital tool and the CARAT online enhanced clinical framework, solutions for practical steps of digital enhancement of care are proposed.Peer reviewe

Consistent patterns of common species across tropical tree communities

Trees structure the Earth’s most biodiverse ecosystem, tropical forests. The vast number of tree species presents a formidable challenge to understanding these forests, including their response to environmental change, as very little is known about most tropical tree species. A focus on the common species may circumvent this challenge. Here we investigate abundance patterns of common tree species using inventory data on 1,003,805 trees with trunk diameters of at least 10 cm across 1,568 locations1,2,3,4,5,6 in closed-canopy, structurally intact old-growth tropical forests in Africa, Amazonia and Southeast Asia. We estimate that 2.2%, 2.2% and 2.3% of species comprise 50% of the tropical trees in these regions, respectively. Extrapolating across all closed-canopy tropical forests, we estimate that just 1,053 species comprise half of Earth’s 800 billion tropical trees with trunk diameters of at least 10 cm. Despite differing biogeographic, climatic and anthropogenic histories7, we find notably consistent patterns of common species and species abundance distributions across the continents. This suggests that fundamental mechanisms of tree community assembly may apply to all tropical forests. Resampling analyses show that the most common species are likely to belong to a manageable list of known species, enabling targeted efforts to understand their ecology. Although they do not detract from the importance of rare species, our results open new opportunities to understand the world’s most diverse forests, including modelling their response to environmental change, by focusing on the common species that constitute the majority of their trees.Publisher PDFPeer reviewe

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
