A retrospective analysis of leadership development through sport

The purpose of this study was to examine the development of six leader-athletes. In-depth qualitative interviews were used to explore the various activities that leader athletes engaged in from an early age as well as the roles and influences that peers, coaches, and parents played within these activities. Results indicated that leadership development in sport focused on developing four central components: high skill, strong work ethic, enriched cognitive sport knowledge, and good rapport with people. The types of activities engaged in throughout development as well as receiving feedback, acknowledgement, support, cognitive engagement, mature conversations with adults, and physical encounters with older peers are important social influences that can play an instrumental role in the formation of these four central tenets.

Never before seen in Brazil: Luis In��cio Lula da Silva's grand diplomacy

Critical assessment of Luis In��cio Lula da Silva's diplomacy, which departed from the previous patterns of the Brazilian Foreign Service, to align itself with the political conceptions of the Workers' Party. This diplomacy has neither consolidated the position of Brazil as a regional leader, nor attained its declared goal of inserting Brazil into the United Nations Security Council, although it has reinforced Brazil's image in the international scenarios; but this was achieved much more through the personal activism of the President himself, than through normal diplomatic work.

Between system maker and privileges taker: the role of China in the Greater Mekong Sub-region

Utilizing China's leadership projects in the Great Mekong Sub-Region (GMS) as a case study, this paper aims to investigate whether China qualifies as an international leader. This work argues that its geographic position and economic rise allow China to be a "system maker and privilege taker," which is a dual role forming in economic-political relations in the GMS in the last ten years. China is among major driving forces to set up an economic zone in GMS. Growing Chinese regional power is intimately related to the creation of various hubs connecting regional transportation, communication and energy systems that foster the economic development of this region. However, China also proves dark sides of rising powers which take advantage of their privileges to gain benefits. As a "system maker" with its own position and capability, China has notably benefited from building hydropower systems. More importantly, while China is pursuing its benefits and privileges, its hydropower projects have caused some negative effects for the ecosystem in the region. The inflation of dam constructions in both China and GMS countries is raising concerns about using natural resources of the Mekong River. Our concluding part addresses the pressing need to start a serious discussion on the balance between national interests and regional solidarity within the formulation of Chinese foreign policy in GMS.

Chinese engagement for Global Governance: aiming for a better room at the table?

The text defends the thesis that China is aware that its process of modernization is still recent and needs more growth, maturation and consolidation to assume the role and responsibilities of a regional or even a global leader. This text pursues an understanding about the Chinese stance in relation to the negotiations for the redefinitions of the International Order and the International System (and, hence, Global Governance) and, secondly, seeks to perceive the reactions of non-developed and developed countries in relation to Chinese strategies.

Motiva����o dos trabalhadores na sociedade do conhecimento

RESUMO: Nas sociedades avan��adas da actualidade, aqui denominadas por sociedades do conhecimento, os n��veis de responsabilidade e de exig��ncia mental das organiza����es para com os seus trabalhadores �� superior a qualquer outra realidade anterior. �� emergente a necessidade de redefinir a estrutura das organiza����es, para que os repons��veis e os seus respectivos colaboradores usufruam de condi����es potenciadoras do seu desempenho profissional. Os perfis ideais dos respons��veis de equipas e , em especial, dos ��novos�� trabalhadores produtores de conhecimento, incorporam determinadas caracter��sticas fundamentais para favorecerem o processo criativo e o trabalho aut��nomo. Mas as altera����es n��o est��o confinadas �� dimens��o laboral, pois surgiram igualmente mudan��as profundas no seio da sociedade, as quais obrigam �� exist��ncia de uma nova rela����o entre a vida pessoal e a vida profissional dos cidad��os. Todas estas transforma����es resultam na necessidade de uma componente motivacional muito forte por parte dos trabalhadores, os quais dependem apenas de si mesmos para a conseguir obter e manter. A solu����o desta problem��tica surge aqui configurada sob a forma de uma mudan��a de atitude por parte de todos os trabalhadores, a qual dever�� fomentar a ocorr��ncia de ��Experi��ncias ��ptimas�� provenientes do desenvolvimento da actividade profissional dos mesmos, tal como �� sugerido pela Teoria do Fluxo. Esta vers��o profunda da motiva����o intr��nseca e est��vel �� proposta como modelar e mesmo fulcral para o trabalhador na Sociedade do conhecimento. ABSTRACT: In today���s advanced societies, here referred as Knowledge Societies, the levels of responsibility and mental demanding which organizations require from their workers is higher than ever before. The need to redefine organizations structures is now emerging in order to allow CEO���s and their co-workers having access to encouraging conditions which improve their work performance. The ideal profile for a team leader and especially for the ��new�� Knowledge production workers, incorporate a defined group of fundamental characteristics to encourage the creative process and the autonomous work. But changes are not confined to the labor dimension. The Society core also suffered profound changes which demand the existence of a new relation between personal and professional life of its citizens. All these changes create the need for the existence of high motivational levels inside all workers, which now have to find their own ways to get and maintain it. The solution for this problem is presented here as a switch in workers attitude, which will increase the occurrence of optimal experiences coming directly from the development of their professional activity like it���s suggested in the flow theory. This version of the deep intrinsic and stable motivation is proposed as a model or even a central solution to the worker in the Knowledge Society.

Pricing intraday dynamics across EUAS and CERS markets

The relative contribution of European Union Allowances (EUAs) and Certified Emission Reductions (CERs) to the price discovery of their common true value has been empirically studied using daily data with inconclusive results. In this paper, we study the short-run and long-run price dynamics between EUAs and CERs future contracts using intraday data. We report a bidirectional feedback causality relationship both in the short-run and in the long-run, with the EUA's market being the leader.

Implementa����o e valida����o de um m��todo de avalia����o do perfil de ��cidos gordos e do teor de gordura em alimentos por cromatografia gasosa

Nos dias de hoje �� necess��rio criar h��bitos de vida mais saud��veis que contribuam para o bem-estar da popula����o. Adoptar medidas e pr��ticas de modo regular e disciplinado, pode diminuir o risco do aparecimento de determinadas doen��as, como a obesidade, as doen��as cardiovasculares, a hipertens��o, a diabetes, alguns tipos de cancro e tantas outras. �� tamb��m importante salientar que, uma alimenta����o cuidada d�� sa��de e aumenta a esperan��a m��dia de vida. Em Portugal, nos ��ltimos anos, os costumes alimentares da popula����o t��m vindo a alterar-se significativamente. As refei����es caseiras confeccionadas com produtos frescos d��o lugar �� designada ���cultura do fast food���. Em contrapartida, os consumidores s��o cada vez mais exigentes, estando em permanente alerta no que se refere ao estado dos alimentos. A rotulagem de um produto, para al��m da fun����o publicit��ria, tem vindo a ser objecto de legisla����o espec��fica de forma a fornecer informa����o simples e clara, correspondente �� composi����o, qualidade, quantidade, validade ou outras caracter��sticas do produto. Estas informa����es devem ser acess��veis a qualquer tipo de p��blico, com mais ou menos forma����o e de qualquer estrato social. A qualidade e seguran��a dos produtos deve basear-se na garantia de que todos os ingredientes, materiais de embalagem e processos produtivos s��o adequados �� produ����o de produtos seguros, saud��veis e saborosos. A Silliker Portugal, S.A. �� uma empresa independente de presta����o de servi��os para o sector agro-alimentar, l��der mundial na presta����o de servi��os para a melhoria da qualidade e seguran��a alimentar. A Silliker dedica-se a ajudar as empresas a encontrar solu����es para os desafios actuais do sector, oferecendo uma ampla gama de servi��os, onde se inclui o servi��o de an��lises microbiol��gicas, qu��micas e sensorial; consultadoria em seguran��a alimentar e desenvolvimento; auditorias; rotulagem e legisla����o. A actualiza����o permanente de procedimentos na procura de uma melhoria cont��nua �� um dos objectivos da empresa. Para responder a um dos desafios colocados �� Silliker, surgiu este trabalho, que consistiu no desenvolvimento de um novo m��todo para determina����o de ��cidos gordos e da gordura total em diferentes tipos de alimentos e compara����o dos resultados, com os obtidos com o m��todo anal��tico at�� ent��o adoptado. Se a gordura �� um elemento de grande import��ncia na alimenta����o, devido ��s suas propriedades nutricionais e organol��ticas, recentemente, os investigadores t��m focado a sua aten����o nos mais diversos ��cidos gordos (saturados, monoinsaturados e polinsaturados), em particular nos ��cidos gordos essenciais e nos is��meros do ��cido linoleico conjugado (CLA), uma mistura de is��meros posicionais e geom��tricos do ��cido linoleico com actividade biol��gica importante. A t��cnica usada nas determina����es foi a cromatografia gasosa com ioniza����o de chama, GC-FID, tendo as amostras sido previamente tratadas e extra��das de acordo com o tipo de matriz. A metodologia anal��tica desenvolvida permitiu a correcta avalia����o do perfil em ��cidos gordos, tendo-se para isso usado uma mistura de 37 ��steres met��licos, em que o ��cido gordo C13:0 foi usado como padr��o interno. A identifica����o baseou-se nos tempos de reten����o de cada ��cido gordo da mistura e para a quantifica����o usaram-se os factores de resposta. A valida����o do m��todo implementado foi baseada nos resultados obtidos no estudo de tr��s matrizes relativas a materiais certificados pela BIPEA (Bureau Interprofessionnel des Etudes Analytiques), para o que foram efectuadas doze r��plicas de cada matriz. Para cada r��plica efectuada foi calculado o teor de mat��ria gorda, sendo posteriormente o resultado comparado com o emitido pela entidade certificada. Ap��s an��lise de cada constituinte foi tamb��m poss��vel calcular o teor em ��cidos gordos saturados, monoinsaturados e polinsaturados. A determina����o do perfil em ��cidos gordos dos materiais certificados foi aceit��vel atendendo aos valores obtidos, os quais se encontravam no intervalo de valores admiss��veis indicados nos relat��rios. A quantifica����o da mat��ria gorda no que se refere �� matriz de ���Pat�� �� Tartinier��� apresentou um z-score de 4,3, o que de acordo com as exig��ncias internas da Silliker, n��o �� v��lido. Para as outras duas matrizes (���M��lange Nutritif��� e ���Plat cuisin�� �� base de viande���) os valores de z-score foram, respectivamente, 0,7 e -1,0, o que permite concluir a validade do m��todo. Para que o m��todo possa vir a ser adoptado como m��todo alternativo �� necess��rio um estudo mais alargado relativamente a amostras com diferentes composi����es. O m��todo foi aplicado na an��lise de amostras de fiambre, leite gordo, queijo, ovo com ��mega 3, amendoim e ��leo de girassol, e os resultados foram comparados com os obtidos pelo m��todo at�� ent��o adoptado.

Methodology for in-game certification in serious games

Serious games are starting to attain a higher role as tools for learning in various contexts, but in particular in areas such as education and training. Due to its characteristics, such as rules, behavior simulation and feedback to the player's actions, serious games provide a favorable learning environment where errors can occur without real life penalty and students get instant feedback from challenges. These challenges are in accordance with the intended objectives and will self-adapt and repeat according to the student���s difficulty level. Through motivating and engaging environments, which serve as base for problem solving and simulation of different situations and contexts, serious games have a great potential to aid players developing professional skills. But, how do we certify the acquired knowledge and skills? With this work we intend to propose a methodology to establish a relationship between the game mechanics of serious games and an array of competences for certification, evaluating the applicability of various aspects in the design and development of games such as the user interfaces and the gameplay, obtaining learning outcomes within the game itself. Through the definition of game mechanics combined with the necessary pedagogical elements, the game will ensure the certification. This paper will present a matrix of generic skills, based on the European Framework of Qualifications, and the definition of the game mechanics necessary for certification on tour guide training context. The certification matrix has as reference axes: skills, knowledge and competencies, which describe what the students should learn, understand and be able to do after they complete the learning process. The guides-interpreters welcome and accompany tourists on trips and visits to places of tourist interest and cultural heritage such as museums, palaces and national monuments, where they provide various information. Tour guide certification requirements include skills and specific knowledge about foreign languages and in the areas of History, Ethnology, Politics, Religion, Geography and Art of the territory where it is inserted. These skills are communication, interpersonal relationships, motivation, organization and management. This certification process aims to validate the skills to plan and conduct guided tours on the territory, demonstrate knowledge appropriate to the context and finally match a good group leader. After defining which competences are to be certified, the next step is to delineate the expected learning outcomes, as well as identify the game mechanics associated with it. The game mechanics, as methods invoked by agents for interaction with the game world, in combination with game elements/objects allows multiple paths through which to explore the game environment and its educational process. Mechanics as achievements, appointments, progression, reward schedules or status, describe how game can be designed to affect players in unprecedented ways. In order for the game to be able to certify tour guides, the design of the training game will incorporate a set of theoretical and practical tasks to acquire skills and knowledge of various transversal themes. For this end, patterns of skills and abilities in acquiring different knowledge will be identified.

Licensing endogenous cost-reduction in a differentiated Stackelberg model

In this paper we consider a differentiated Stackelberg model, when the leader firm engages in an R&D process that gives an endogenous cost-reducing innovation. The aim is to study the licensing of the cost-reduction by a two-part tariff. By using comparative static analysis, we conclude that the degree of the differentiation of the goods plays an important role in the results. We also do a direct comparison between our model and Cournot duopoly model.

Flexibility in a Stackelberg leadership with differentiated goods

We study the effects of product differentiation in a Stackelberg model with demand uncertainty for the ���rst mover. We do an ex-ante and ex-post analysis of the pro���ts of the leader and of the follower ���rms in terms of product differentiation and of the demand uncertainty. We show that even with small uncertainty about the demand, the follower ���rm can achieve greater pro���ts than the leader, if their products are suf���ciently differentiated. We also compute the probability of the second ���rm having higher pro���t than the leading ���rm, subsequently showing the advantages and disadvantages of being either the leader or the follower ���rm.
