RESILIÊNCIA DE ATLETAS DE BASQUETEBOL

Resiliência remete à habilidade do ser humano de demonstrar êxito diante das adversidades da vida, superá-las e, inclusive, ser fortalecido ou transformado por elas. O construto tem sido estudado há cerca de quarenta anos na Psiquiatria com foco em crianças, mas sua investigação é bem mais recente com a população adulta. No mundo da competição esportiva, os estudos são escassos. O contexto esportivo apresenta altos desafios e adversidades constantes que os atletas precisam vencer para cumprir as metas profissionais; por isso, convivem, muito frequentemente, com seus limites físicos e psicológicos. Assim, a resiliência pode ser um importante aspecto em suas vidas profissionais. Este estudo objetiva descrever os níveis de resiliência dos atletas no Basquetebol e identificar possíveis relações entre resiliência e alguns indicadores de eficiência estatística. Participaram da pesquisa, voluntariamente, 71 atletas profissionais adultos e atuantes da modalidade. As variáveis foram avaliadas por meio da Escala de Avaliação de Resiliência EAR, de um questionário de dados sociodemográficos e de índices de eficiência registrados pela Federação Paulista de Basquetebol. Os resultados de análises estatísticas descritivas e de correlações bivariadas de Pearson permitiram observar que os atletas demonstraram um alto nível de resiliência com destaque para a persistência diante das dificuldades e a aceitação positiva de mudanças. Os fatores que compõem a resiliência não apresentaram correlação significativa no tocante ao coeficiente de eficiência dos atletas. Ao comparar as médias por meio da análise de variância percebeu-se que os atletas que possuíam entre cinco e dez anos de profissão apresentaram melhores médias de coeficiente de eficiência. Os resultados revelam, ainda, que os atletas que atuam menos de 8 minutos na partida, em média, produzem menores índices de eficiência estatística e que os atletas que pertencem às equipes de resultados medianos na tabela de classificação tendem a apresentar maior percepção de competência pessoal que os atletas que atuam nas equipes mais mal colocadas. Os fatores de resiliência não se diferenciam em função da experiência dos atletas, nem do tempo em média que permanecem em quadra. Esses resultados revelam a necessidade de questionar se os indicadores de eficiência estatística seriam os critérios mais adequados para verificar o papel da resiliência na vida de atletas de Basquetebol e apontam para a necessidade de aumentar o número de estudos sobre a influência de características individuais no mundo dos esportes profissionais.

COACHING E MENTORING COMO PRÁTICAS DE COMPARTILHAMENTO DO CONHECIMENTO: ESTUDOS DE CASOS EM EMPRESAS PÚBLICAS PAULISTAS

A pesquisa teve como objetivo geral analisar as principais razões pelas quais as empresas públicas paulistas utilizam coaching e mentoring como práticas de compartilhamento de conhecimento. No ano de 2009, foi instituído pelo governador do Estado de São Paulo, o decreto nº 53.963 que instituiu a Política de Gestão do Conhecimento e Inovação para as empresas públicas. Kuniyoshi e Santos (2007) realizaram uma pesquisa, na qual identificaram práticas e iniciativas de gestão do conhecimento adotadas por algumas empresas, dentre elas, coaching e mentoring. As práticas são processos que necessitam de investimento não somente financeiro, mas de tempo e pessoas adequadas, por serem processos mais complexos, instigam a investigação de ações no contexto organizacional de empresas públicas. Este estudo busca contribuir para o desenvolvimento de estudos na área pública. O método utilizado neste estudo de abordagem qualitativa é do tipo exploratória. O objeto desta pesquisa foram as empresas públicas paulistas, que, atualmente, somam 21. Foi realizado estudo de caso, com entrevista e análise documental em duas destas empresas, A Sabesp, empresa do segmento de saneamento de água e esgoto, teve como objetivo analisar a prática de coaching e, o Instituto de Pesquisa Tecnológicas (IPT), referência nacional em metrologia, teve como objetivo analisar a prática de mentoring. Uma vez que não existem práticas exclusivas à Gestão do Conhecimento, e o sucesso de uma prática está relacionado ao contexto na qual está inserida. No caso da Sabesp, a prática de coaching é utilizada como uma das atividades dentro de dois programas, visando desenvolver o capital humano como força competitiva. O IPT teve como objetivo da aplicação do programa de mentoring, especificamente, o compartilhar conhecimento tácito. Foi constatado que as práticas de coaching e mentoring podem ser utilizadas como recurso capaz de tornar a empresa singular perante as demais, mesmo empresas públicas não tendo foco em competitividade, mas utilizam o conhecimento de forma estratégica para melhorar a qualidade de atendimento à sociedade.

The intra-firm diffusion of complementary innovations: Evidence from the adoption of management practices by British establishments

This paper presents a simple profitability-based decision model to show how synergistic gains generated by the joint adoption of complementary innovations may influence the firm's adoption decision. For this purpose a weighted index of intra-firm diffusion is built to investigate empirically the drivers of the intensity of joint use of a set of complementary innovations. The findings indicate that establishment size, ownership structure and product market concentration are important determinants of the intensity of use. Interestingly, the factors that affect the extent of use of technological innovations do also affect that of clusters of management practices. However, they can explain only part of the heterogeneity of the benefits from joint use.

Antecedents of strategic flexibility:management cognition, firm resources and strategic options

Purpose: Current conceptualisations of strategic flexibility and its antecedents are theory-driven, which has resulted in a lack of consensus. To summarise this domain the paper aims to develop and present an a priori conceptual model of the antecedents and outcomes of strategic flexibility. Discussion and insights into the conceptual model, and the relationships specified, are made through a novel qualitative empirical approach. The implications for further research and a framework for further theoretical development are presented. Design/methodology/approach: An exploratory qualitative research design is used applying multiple data collection techniques in a branch network of a large regional retailer in the UK. The development of strategic options and the complex relationship to strategic flexibility is investigated. Findings: The number and type of strategic options developed by managers impact on the degree of strategic flexibility and also on the ability of the firm to achieve competitive differentiation. Additionally, the type of strategic option implemented by managers is dependent on the competitive situation faced at a local level. Evidence of managers' limited perception of competition was identified based on their spatial embeddedness. Research limitations/implications: A single, in-depth case study was used. The data gathered is rich and appropriate for the exploratory approach adopted here. However, generalisability of the findings is limited. Practical implications: Strategic flexibility is rooted in the ability of front-line mangers to develop and implement strategic options; this in turn facilitates competitive differentiation. Originality/value: The research presented is unique in this domain on two accounts. First, theory is developed by presenting an a priori conceptual model, and testing through in-depth qualitative data gathering. Second, insights into strategic flexibility are presented through an examination of managerial cognition, resources and strategic option generation using cognitive mapping and laddering technique. © Emerald Group Publishing Limited.

Nutritional management of blood glucose levels

Background and Objectives: Nutritional management of blood glucose levels is a strategic target in the prevention and management of type 2 diabetes mellitus (T2DM), applicable across the population. To implement a successful strategy it is essential to understand the impact of dietary modulation on the postprandial rise in blood glucose concentrations. Methods: Using the highest quality data, a systematic and comprehensive literature review was undertaken. Included in this review were the major macronutrients (carbohydrate, pro-tein, fat), micronutrient vitamins and minerals, non-nutrient phytochemicals and additional foods such as low-calorie sweeteners, vinegar and alcohol. Results: The strongest corroboration of efficacy for improving glucose homeostasis was for insoluble and moderately fermentable cereal-based fiber and mono-unsaturated fatty acids as replacement of saturated fat. Postprandial glycaemia was decreased by intake of viscous soluble fiber and the predominant mechanism of action was considered to be by delaying absorption of co-ingested carbohydrates. There was weaker but substantial evidence that certain phytochemical-rich foods were likely to be effective. This may be associated with the su-ggestion that the gut microbiota plays an important role in me-tabolic regulation, which includes provision of phytochemical and other metabolites. Conclusions: Based on the evidence, it is clear that dietary components have significant and clinically relevant effects on blood glucose modulation. This suggests that employing a dietary regimen to attenuate the postprandial rise in blood glucose levels along with previously identified targets (reducing excess body weight and an increase in physical activity) will benefit the health of the population and limit the increasing worldwide incidence of T2D.

Adómorál és adócsalás - társadalmi preferenciák és korlátozott racionalitás = Tax morale and tax system: social preferences and bounded rationality

Az adócsalásnak egy olyan modellcsaládját vizsgáljuk, ahol az egykulcsos adó kizárólag a közjavakat finanszírozza. Két megközelítés összehasonlítására összpontosítunk. Az elsőben minden dolgozó jövedelme azonos, és ebből minden évben annyit vall be, amennyi maximalizálja a nála maradó jövedelemből fedezhető fogyasztás nyújtotta hasznosság és a jövedelembevallásból fakadó hasznosság összegét. A második hasznosság három tényező szorzata: a dolgozó exogén adómorálja, a környezetében előző évben megfigyelt átlagos jövedelembevallás és saját bevallásából fakadó endogén hasznossága. A második megközelítésben az ágensek egyszerű heurisztikus szabályok szerint cselekszenek. Míg az optimalizáló modellben hagyományos Laffer-görbékkel találkozunk, addig a heurisztikán alapuló modellekben (lineárisan) növekvő Laffer-görbék jönnek létre. E különbség oka, hogy a heurisztikán alapuló modellben egy sajátos viselkedésfajta jelentkezik: számos ágens ingatag helyzetbe kerül, amelyben altruizmus és önzés között ingadozik. ________ The authors study a family of models of tax evasion, where a flat-rate tax only finances the provision of public goods and audits and wage differences are ne-glected. The paper focuses on comparing two modelling approaches. The first is based on optimizing agents, endowed with social preferences, their utility being the sum of private consumption and moral utility. The second approach involves agents acting according to simple heuristics. While the traditionally shaped Laffer curves are encountered in the optimizing model, the heuristics models exhibit (linearly) increasing Laffer curves. This difference is related to a peculiar type of behaviour: within the agent-based approach lurk a number of agents in a moral state of limbo, alternating between altruism and selfishness.

Kihívások és lehetőségek a hazai megújuló energiaszektorban (Challenges and possibilities in the Hungarian renewable sector)

A megújuló energiatermelés szerepének erősödését figyelhetjük meg az utóbbi években, évtizedekben. A zöldenergiák iránti igényt három fő motivátorcsoporttal lehet indokolni: ellátásbiztonság növelése, környezetvédelem és gazdaságélénkítés. Ezek a szempontok együttesen a fenntartható fejlődést szolgálják, és egyre inkább előtérbe kerülnek mind az EU, mind pedig hazánk szintjén. Magyarország 2010 végén az EU által előírt, 2020-ra elérendő 13%-os megújuló energiaarányt meghaladó, 14,65%-os vállalást tett a Nemzeti Cselekvési Tervben, ezzel is kifejezve elköteleződését a zöldenergiák ösztönzése felé. A jelenlegi kapacitások több mint megkétszerezését igénylő cél a hazai megújuló energiaszektor számára érdemi lehetőségeket jelent, de ezek megvalósításához szükség lenne az ígért új zöldenergia-támogatási rendszer, mielőbbi életbe lépésére. ____ The role of the renewable energy generation is getting even bigger and bigger in the last years, decades. The demand for the green energy has three main motivators: energy security, protecting the environment and fostering innovation. These goals serve the conception of sustainable development, and their function is increasingly highlighted in the EU and in Hungary as well. The EU has prescribed Hungary to reach a 13% share of renewable energy sources in 2020, but in the Hungarian national renewable action plan we have aimed to top the EU request, and to reach a 14,65% in the renewable proportion. This shows that our country is committed to inspire the renewables. In order to reach this goal, Hungary has to more than double its green power plant capacity, which means great possibilities in the sector; but at the same time means challenges as well, because the new renewable promoting system needs to come into force as soon as possible.

Global compilation of benthic data sets I

Approaches to quantify the organic carbon accumulation on a global scale generally do not consider the small-scale variability of sedimentary and oceanographic boundary conditions along continental margins. In this study, we present a new approach to regionalize the total organic carbon (TOC) content in surface sediments (<5 cm sediment depth). It is based on a compilation of more than 5500 single measurements from various sources. Global TOC distribution was determined by the application of a combined qualitative and quantitative-geostatistical method. Overall, 33 benthic TOC-based provinces were defined and used to process the global distribution pattern of the TOC content in surface sediments in a 1°x1° grid resolution. Regional dependencies of data points within each single province are expressed by modeled semi-variograms. Measured and estimated TOC values show good correlation, emphasizing the reasonable applicability of the method. The accumulation of organic carbon in marine surface sediments is a key parameter in the control of mineralization processes and the material exchange between the sediment and the ocean water. Our approach will help to improve global budgets of nutrient and carbon cycles.
