Effects of Feedback on Self-Efficacy Expectations Based on the Athlete’s Optimistic Profile  [PDF]
Ricardo de la Vega, Roberto Ruiz, Francisco Batista, Francisco Ortín, Carlos Giesenow
Psychology (PSYCH) , 2012, DOI: 10.4236/psych.2012.312A179
Abstract:

In recent years, the study of optimism and its possible influence on athletic performance has increased considerably. The key purposes of this study can be summarized as: 1) analyze how self-efficacy expectations vary depending on the level of optimism an individual has; 2) ascertain how progressively receiving negative feedback affects performance expectations; and 3) evaluate whether there are differences in per- formance depending on the presence or absence of feedback. In order to achieve this, 53 Spanish football players were assessed using the Revised Life Orientation Test and an objective test of strength using hand dynamometry. The level of feedback provided was manipulated to study its influence on perceived self- efficacy in the applied strength task. The results show no significant difference between the three levels of optimism/pessimism respecting self-efficacy. Significant differences do appear when the effects of the in- dividual feedback provided for each experimental group is analyzed. The findings are discussed and future research is proposed based on the results obtained.

Abstract: O município de Matinhas, Estado da Paraíba com aproximadamente 1,3 milh es de plantas de tangerina, é responsável por 90% da produ o do Estado. A pesquisa foi conduzida em cinco regi es geográficas do município de Matinhas, onde foram coletados 20 frutos na copa e 20 sob a copa da planta, objetivando pesquisar a ocorrência de moscasfrugívoras e seus níveis de infesta o em tangerina. Os resultados obtidos evidenciaram que a tangerina é infestada por Ceratitis capitata (Wiedmann,1824), Neosilba zadolicha (McAlpine e Steyskal) e Neosilba glaberrima (Wiedmann,1830). O índice médio de infesta o de C. capitata nas cinco regi es n o ultrapassou 0,5 pupa fruto-1. A percentagem de emergência (P.E.) de C. capitata em frutos coletados na planta e solo variou entre 14,0 a 54,0% de adultos fruto-1. Osíndices de infesta o de N. zadolicha, em frutos coletados na planta e solo, variaram entre 0,4 a 4,3 pupários fruto-1. Os dados da percentagem de emergência (P.E.) de N. zadolicha variaram entre 49,9 a 65,9% de adultos fruto-1, sendo considerada a espécie mais abundante, dominante e com uma alta taxa de sobrevivência. N. zadolicha foi considerada praga primária da tangerina nas condi es de Matinhas. Este é, também, o primeiro relato das espécies N. zadolicha e N. glaberrima infestando tangerina na Paraíba.

Abstract: O objetivo dessa pesquisa foi avaliar a eficiência do tratamento hidrotérmico no controle de larvas de C. capitata em frutos de tangerina para fins quarentenários. Tangerinas da variedade ‘Dancy’ infestadas por larvas de Ceratitis capitata foram submetidas aostratamentos hidrotérmicos de 46±1°C e 50±1°C, em diferentes tempos de exposi o. Para a temperatura de 46±1°C foram utilizados nove períodos de exposi o: 0, 5, 10, 15, 20, 25, 30, 35 e 40 min. Na temperatura de 50±1°C, utilizaram-se sete tempos de exposi o: 0, 5,10, 15, 20, 25 e 30 min., sendo o tempo (0) infestado e sem tratamento para as duas temperaturas. Cada tratamento foi composto de cinco repeti es com dois frutos. Frutos maduros e semi-maduros infestados foram imersos em água quente, visando quantificar ototal de larvas vivas e mortas, sendo que, um grupo de frutos foi mantido sem imers o como controle. Os índices quarentenários, na temperatura de 46±1°C foram atingidos aos 32,0 e 35,3 min. para frutos maduros e semi-maduros, respectivamente. Na temperatura de50±1°C, os índices quarentenários foram atingidos aos 20,8 e 21,7 minutos para os frutos maduros e semi-maduros, respectivamente.

Engenharia Ambiental : Pesquisa e Tecnologia , 2009,
Abstract: The insect Dactylopius opuntiae (cochineal carmine) has become an important pest to giant cactus pear (Opuntia ficus-indica) in several counties of the micro regions of Carirí Ocidental, Serra do Teixeira and Piancó, where the attack of the insect is so intense that it obliges farmers to eradicate crops. This research aimed to quantify the dispersal speed of D. opuntiae under field conditions, as a premise for the implementation of tactics of the Integrated Pest Management (IPM). The experiment was carried out at the Lagoa Seca Experimental Station, in Lagoa Seca County, state of Paraiba. Dispersion quantification was conducted in three rows of giant cactus pear each with ten plants, the first being selected to perform the artificial infestation (initial). Three evaluations was carried out in three rows and counted the average number of colonies arising from the initial infestation. Medium comparison of was made by Tukey test at 5% probability, using the application ASSISTAT 7.5 Beta. For the aspect of dispersion within each plant, it was observed that the artificially infested cladodes began to be colonized for 8 days after infection and subsequently at 15, 21, 28, 35 and 42 and 50 days, noting that equally the first, second and third rows were also colonized, showing thus the dispersal speed of the insect pest.

Abstract: Since its introduction, in 2001, the carmine cochineal (Dactylopius opuntiae) already decimated some 100.000 hectares of giant cactus pear (Opuntia ficus-indica) in semi-arid region of Paraiba. This study aimed to evaluate the behavior of five concentrations of orange oil, applied in cladodes on the death of D. opuntiae in field conditions. The research was carried out in a field of giant cactus pear infested by carmine cochineal on the site rigideira, Monteiro County, State of Paraíba. The trial design used was blocks at random (DBR) composed of six treatments [doses of 0.3, 0.4, 0.5, 0.6, and 0.7% of orange oil (Prev-am)] and water as control and five repetitions. The orange oil known like Prev-Am (Sodium tetraborohydrate decahydrate) was effective against to carmine cochineal as early as the dose of 0.3% and higher potential for efficiency were observed at doses of 0.6 and 0.7%. After 48 hours of application of the product, which was observed at doses applied adults and nymphs of the insect, was dried according to the product action that acts by contact. The product had no lethal effect on ladybugs (Cycloneda sanguinea and Scymnus intrusus), but was lethal to larvae of Baccha sp. at a dose of 0.7%.

Abstract: The concept of agroecology is on the concept of sustainable development whose primary objective is combining economic development with environmental conservation, being able to meet the needs of the current generation without depleting resources for the future. The municipality of Areia - PB has always had its economic development in footwear production and its derivatives, is known as "Land of rum and Rapadura”, two icons of the agricultural economy of Areia. Presents favorable conditions of climate, soil and topography in order to enable the coexistence of diverse cultures and its variations, however, local farmers only cultivate crops as banana, cassava, maize, beans and sugar-cane. This work aimed to evaluate the profile of the producer and the production of the municipality of Areia - PB, via a questionnaire applied to five associations of farmers and producer's fair, where you can see that the majority of producers are illiterate or just read or write, characteristic of small areas have on average 1 to 3 ha; occurs traditional cultivation of maize, beans and cassava, banana, and grown on a smaller scale are found orange, sugar-cane, sweet potatoes and vegetables, production is characteristic of subsistence.Key-words: agroecology, sustainable development, food security.

Engenharia Ambiental : Pesquisa e Tecnologia , 2009,
Abstract: In 2001 was introduced in the State of Paraíba, the exotic pest Dactylopius opuntiae, commonly known as carmine cochineal, which already undertaken the cultivation of the giant cactus pear (Opuntia ficus-indica) in more than fifty cities. This study aimed to evaluate the infestation and dispersal speed of D. opuntiae at the field conditions, to establish a level of pest control. The research was performed in a field of giant cactus pear with twelve months cropped, artificially infested with the carmine cochineal in Lagoa Seca Experimental Station, Paraíba. The trial used was the completely randomized design (CRD) consisting of ten treatments (giant cactus pear plants) and ten repetitions (infested cladodes). Data were submitted to analysis of variance, using the ASSISTAT Application 7.5 Beta (2008). The results showed that ten colonies/cladodes caused infestation and a high dispersion of the insect. After 60 days the infestation and spread of colonies reached average value 171 colonies per plant. The dispersal of migrants nymphs are carried by wind from the cladodes to cladodes and plant to plant. From these results we can establish that the control level to carmine cochineal is less than 10 colonies/plant and the combat should be started immediately after detection of the first colonies of the pest in cactus pear crop.

Engenharia Ambiental : Pesquisa e Tecnologia , 2009,
Abstract: In semi-arid region of Northeast, Brazil, the giant cactus pear is a forage that contains, on average, 90% water and helps to relieve the thirst of the catlle, mainly in the dry season. The use of Opuntia ficus-indica as fodder for animals has been gaining space, especially in the states of Alagoas, Pernambuco and Paraiba. This study aimed to investigate the effects of curing of cladodes in root emission in giant cactus pear. An experiment was established composed of 300 cladodes, planted with spacing of 0.5 x 0.5 m, a total area of 100 m2 where the soil was classified as Neossol Regolithic Eutrophic. The cure of cladodes was conducted in the shade for a period of 0, 8, 16, 24 and 32 days. The results showed that the best treatment and that provided the greatest number of roots was the period of curing for 32 days and planted at 15 days. The greatest length of giant cactus pear roots was obtained when the cladodes were subjected to a cure period of 32 days and planted to 25 days after cure. Cladodes planted and harvested the same day, even in dry soil, rotting due to infection caused by the bacterium Erwinia carotovora atroseptica sub-species.
