Análise dos fatores externos no desempenho do basquetebol

O presente estudo teve com objetivo analisar alguns fatores externos que podem interferir durante uma partida de basquetebol e tentar desvendar quais destes são encarados pelos jogadores como os que têm a maior influência durante o jogo. Buscamos através de um questionário, onde haviam oito questões, estudar a influência da torcida, dos pais, e do técnico com relação ao desempenho de jogadores de basquete da cidade de Rio Claro - SP. Foram entrevistados treze jovens do sexo masculino praticantes de basquetebol na cidade de Rio Claro - SP, na faixa etária de 15 a 17 anos, com tempo de pratica variando de um a quatro anos e treinando cinco vezes por semana. Os principais resultados obtidos foram: A maioria dos entrevistados respondeu que sofre uma influência negativa da torcida adversária; 46,15% dos entrevistados não sofrem nenhum tipo de influência devido à presença dos pais na torcida; A conduta do técnico durante os treinos e os jogos pode influenciar no resultado do jogo; 84,62% responderam que os árbitros podem ter seu desempenho diminuído com a pressão da torcida; A maioria dos entrevistados (69,24%) acha que o técnico, por estar junto da equipe durante os treinos e os jogos, tem uma influência maior no desempenho dos atletas.

Proposta de diretrizes embasadoras para introdução de sistemas de medição de desempenho em empresas de projetos de instalações prediais

The civil construction in Brazil has grown a lotover the last years. This has caused a greater competition between companies of the sector. A little difference in quality in service or product a company offers can determine their success in the market. There is a growing demand for tools that optimize processes and bring greater quality to each activity in these companies. Performance measurement systems make it possible to control process efficiency and effectiveness using performance indicators. Considering this need, the paper before you has the objective of creating basic guidelines to introduce performance measurement systems inbuilding installations project companies. A theoretical reference is presented to describe organizational aspects of project companies along with performance measurement systems characteristics. Using a qualitative research methodology, a study case was executed with interviews, observation and document analysis as evidence sources. In the study case, limitations where identified, such as, high degree of product and process flexibility, dependence on subjective analysis for decision making and lack of specialized information systems. Considering the theoretical reference and the study case,the proposed guidelines intend to ease and guarantee greater chances of success when implanting one of these systems

A interferência da desmotivação no desempenho de atletas

A motivação pode ser considerada um dos mais importantes combustíveis do ser humano, e seu estudo é importante principalmente na compreensão da influência da motivação sobre o desempenho esportivo e o bem-estar dos atletas. Ela pode ser caracterizada por fatores pessoais (motivação intrínseca) e ambientais (motivação extrínseca). Dentre os fatores motivacionais, o técnico tem grande importância pois, na maioria das vezes, partirão destes o incentivo que poderá influenciar diretamente nos atletas um comportamento motivado. No caso de estar desmotivado, um esportista não desempenhará ou desempenhará mal sua tarefa. Por isso, 22 atletas de handebol masculino, categoria adulto, das equipes SEME Rio Claro e Handebol Itu, responderam um questionário, onde buscava-se investigar a falta de motivação e pensamentos de abandono. Foram encontrados resultados que corroboram com a literatura, nos quais as causas da desmotivação estão relacionadas, principalmente, às dificuldades de relacionamento com o técnico, monotonia dos treinamentos, decepção das expectativas, sentimento de isolamento diante da equipe técnica e carência de reforços positivos pelos resultados conseguidos. Esses mesmos motivos, além de outros, como lesões, são causas do abandono esportivo. Porém, os resultados obtidos sugerem que os atletas pesquisados, mesmo os que se mostraram desmotivados, não apresentaram, em sua maioria, propensão a parar de praticar handebol, mostrando que falta de motivação e pensamentos de abandono do esporte podem estar presentes entre atletas, em maior ou menor grau. Ainda que não se intensifiquem a ponto de resultar em abandono.

Análise de desempenho de lâmpadas LEDs e LFCs como alternativas em iluminação residencial em função da implementação da portaria ministerial n° 1007 que limita o uso de lâmpadas incandescentes no Brasil

With the imposition of the suspension of production and subsequent banning of incandescent light bulbs will be necessary to replace it by other more energy-efficient. Although the main alternative is the compact fluorescent lamp, the environmental impact caused by it due to incorrect disposal and the amount of harmonics included in the network resulting in losses related to the quality of electric power system makes them sought new alternatives for lighting systems that are efficient and have low environmental impact. In this context, the LED (Lighting Emitting Diode), based on solid-state components, is presented as an option for new projects and replacement of existing lighting. In this work we studied aspects of energy, environmental and economic impacts of a possible replacement of conventional lighting systems for new technology. From laboratory tests and surveys of the costs of different types of lamps used for residential lighting, we performed a comparative analysis considering energy and economic aspects which showed that the LED technology, but has a high initial investment, it is best when power quality and environmental preservation are relevant factors in decision making for the choice of technology to be used in the lighting system

O efeito da autocorrelação no desempenho dos gráficos de X e R e dos gráficos de X e S²

Control charts are very important tools in statistical quality control of industrial processes and its use started last century. Since its development, the charts have always been attributed to independent processes, i.e. without any correlation between samples. But nowadays, with the high level of automation in the industrial environment, it is noticeable the autocorrelation factor between samples. The main Xcharts used in monitoring quality characteristics represented by continuous variables are the mean (X ), amplitude (R) and variance (S²). Therefore, this work aims to analyze the performance of X and R charts and in of X and S² charts with different sample sizes (4 and 5) for monitoring autocorrelated processes. Through computer simulations using the Fortran software and the use of mathematical expressions was possible to obtain data and performance analysis of the detection power charts for independent observations and for autocorrelated observations according to the model AR (1). The results show that the effect of autocorrelation reduces the ability of monitoring the control charts and that, the greater this effect, the slower the chart becomes in misfits signaling

Interferência do bullying no esporte de alto rendimento

Examine the phenomenon of bullying behavior that makes people teased, laughter, sarcasm, irony, among other types of attacks. This is not only physically, but with moral violence, emotional or psychological. When there is an effective intervention against bullying, all individuals in the group start to suffer with this situation, which can lead to psychological disorders, hampering the progress of relations as well as team sports, over a period of training and competition. This article analyzed a sample of athletes in order to find behaviors that characterize the extent of bullying and can see the consequences of it, as early drop out. Through the results it was concluded that the actions that characterize bullying are present in very high performance football and may even lead to drop out the sport. We also evaluate the environments frequented by teams can become enhancers of this phenomenon, they are times when athletes have a living space and one that may become amenable to the events, plus the fact that many athletes have already thought about leaving the sport because to bullying
