Avaliação da Harmonia Facial em Relação às Proporções Divinas de Fibonacci

ResumoDe acordo com alguns autores, as faces consideradas belas apresentam-se em Proporção Divina, ou seja, na relação de 1:0,618. Esta pesquisa investiga se essa proporção manifesta-se nas faces de pessoas selecionadas por avaliadores, utilizando, para tal, o critério de beleza. A amostra inicial foi composta por 104 pessoas, previamente selecionadas e separadas em grupos M (masculino) e F (feminino), sendo realizados, de cada participante, dois registros fotográficos (A e B). A partir do registro fotográfico A, obtiveram-se fotografias (frontal e lateral), que foram submetidas ao exame por um grupo de avaliadores. De posse dos valores atribuídos, foram identificados os sujeitos que comporiam a amostra final, assim constituída: subgrupos M1 e F1 (10 pessoas com valor numérico maior) e M2 e F2 (10 pessoas com valor numérico menor), totalizando uma amostra final de 80 fotografias (frontais e laterais) a partir do registro fotográfico B. Prosseguiuse com a análise facial propriamente dita. Os dados obtidos foram comparados com a Proporção Divina, observando-a em apenas duas das proporções avaliadas. Assim, pode-se afirmar que a Proporção Divina não está associada à percepção da beleza no contexto desta pesquisa.AbstractIn agreement with some researched authors the beautiful faces are in divine proportion or 1:0,618. The present study was developed with the intention of investigating if the people selected by appraisers using the criterion of facial beauty shows the divine proportion. The initial sample was obtained starting from 104 people selected previously and separate in groups M (male) and F (female) being accomplished two photographic registrations of each participant (A and B). Starting from the photographic registration A was obtained pictures (frontal and lateral) which underwent the evaluation for a group of appraisers. With the rates attributed by the appraisers was identified the subjects that would compose the final sample constituted like this: subgroups M1 and F1 (10 people with larger numeric rate) and M2 and F2 (10 people with smaller numeric rate) totaling a final sample of 80 pictures (frontal and lateral) starting from the photographic registration B. Proceeding with the facial analyses. The obtained data were compared with the divine proportion and only in two proportions happened identification with these rates. Like this would be affirmed that the divine proportion is not associated to the perception of the beauty in the context of this research

Resposta de cultivares de trigo à infestação do pulgão Rhopalosiphum padi.

O objetivo deste trabalho foi avaliar a resposta de oito cultivares comerciais de trigo (BRS 194, BRS 208, BRS Camboatá, BRS Guabiju, BRS Guamirim, BRS Louro, BRS Timbaúva e BRS Umbu) à infestação do pulgão Rhopalosiphum padi (Hemiptera: Aphididae). O experimento foi realizado na Embrapa Trigo, em telado, em blocos ao acaso, com oito tratamentos e seis repetições, dispostos em parcelas subdivididas. As parcelas principais receberam os tratamentos com e sem infestação de pulgões, e as subparcelas foram compostas pelas cultivares. A infestação com os pulgões (20 adultos ápteros por planta) foi realizada aos 12 dias após a emergência das plantas, quando se encontravam no início do afilhamento, e foi mantida durante 15 dias. As cultivares avaliadas responderam diferentemente à infestação do pulgão R. padi. A cultivar BRS Timbaúva é a mais resistente, e as cultivares BRS Umbu e BRS Guabiju são as mais suscetíveis ao pulgão, quanto ao crescimento e a capacidade produtiva de plantas

Perceived control and hedonic tone dynamics during performance in elite shooters

Purpose: The purpose of the study was to investigate the individuals' dynamics of perceived control and hedonic tone over time, with respect to the 4 performance states as conceptualized within the multiaction plan (MAP) model. We expected to find idiosyncratic and differentiated trends over time in the scores of perceived control and hedonic tone, typified by fluctuations among 2 optimal and 2 suboptimal types of processing during performance. Method: Ten elite-level shooters participated in the study. They were asked to identify the most relevant, idiosyncratic core component of their shooting action and perform 120 shots distanced 10 m from the target. Subjective accounts of perceived control and hedonic tone of the core component of action were assessed prior to and after each shot. We used a probabilistic approach to derive the 4 performance categories according to 2 × 2 interactions of perceived control and performance and hedonic tone and performance. Results: Logistic ordinal regression analysis enabled the identification of 4 idiosyncratic performance types for each athlete with respect to perceived control and hedonic tone intensity scores. Within- and between-individual differences in intensity bandwidth and probability levels were apparent across the 4 performance types. Changes among 4 types of processing were also observed during performance. Conclusion: Consistent with the MAP model conceptualization, the findings provided support for the different patterns of perceived control and hedonic tone intensity scores during performance. The results suggest applied arguments for using action- and emotion-centered strategies to help athletes in reaching and sustaining optimal performance states

COLLECTIVE CATERING AND MICROBIOLOGICAL CONTROL: RESULT OF SURVEYINGS AT COOKING CENTRES DURING YEAR 2010

In this article was made up statistics on food samples collected in 2010 at cooking centers and analyzed for the presence of pathogenic or non-patogenic microorganisms. The results shows that most of the samples respects the limits imposed by reg. 2073/2005, due to the good manufacturing practices and application of HACCP

Recovery and performance in sport: Consensus statement

© 2018 Human Kinetics, Inc. The relationship between recovery and fatigue and its impact on performance has attracted the interest of sport science for many years. An adequate balance between stress (training and competition load, other life demands) and recovery is essential for athletes to achieve continuous high-level performance. Research has focused on the examination of physiological and psychological recovery strategies to compensate external and internal training and competition loads. A systematic monitoring of recovery and the subsequent implementation of recovery routines aims at maximizing performance and preventing negative developments such as underrecovery, nonfunctional overreaching, the overtraining syndrome, injuries, or illnesses. Due to the inter- and intraindividual variability of responses to training, competition, and recovery strategies, a diverse set of expertise is required to address the multifaceted phenomena of recovery, performance, and their interactions to transfer knowledge from sport science to sport practice. For this purpose, a symposium on Recovery and Performance was organized at the Technical University Munich Science and Study Center Raitenhaslach (Germany) in September 2016. Various international experts from many disciplines and research areas gathered to discuss and share their knowledge of recovery for performance enhancement in a variety of settings. The results of this meeting are outlined in this consensus statement that provides central definitions, theoretical frameworks, and practical implications as a synopsis of the current knowledge of recovery and performance. While our understanding of the complex relationship between recovery and performance has significantly increased through research, some important issues for future investigations are also elaborated
