International conference site selection criteria : And a case study of Stockholm as an international conference city

The purpose of this thesis is to identify the destination site selection criteria for internationalconferences from the perspectives of the three main players of the conference industry,conference buyers (organizers and delegates) and suppliers. Additionally, the researchidentifies the strengths and weaknesses of the congress cities of Stockholm and Vienna.Through a comparison with Vienna, the top city for hosting international conferences, a roadmap for Stockholm has been designed, to strengthen its congress tourism opportunities, thus,obtaining a higher status as an international congress city. This qualitative research hascombined both primary and secondary data methods, through semi-standardized expertinterviews and secondary studies respectively, to fulfil the study’s aim. The data have beenanalysed by applying the techniques of qualitative content analysis; the secondary dataadopting an inductive approach according to Mayring (2003) while the expert interviewsusing a deductive approach according to Meuser & Nagel (2009). The conclusions of thesecondary data have been further compared and contrasted with the outcomes of the primarydata, to propose fresh discoveries, clarifications, and concepts related to the site selectioncriteria for international conferences, and for the congress tourism industry of Stockholm. Theresearch discusses the discoveries of the site selection criteria, the implications of thestrengths and weaknesses of Stockholm in comparison to Vienna, recommendations forStockholm via a road map, and future research areas in detail. The findings andrecommendation, not only provide specific steps and inceptions that Stockholm as aninternational conference city can apply, but also propose findings, which can aid conferencebuyers and suppliers to cooperate, to strengthen their marketing strategies and developsuccessful international conferences and destinations to help achieve a greater competitiveadvantage.

An assessment of criteria to evaluate the graduate education program in Brazil

This study sought to identify criteria adequate for the evaluation of graduate programs in Brazil. A survey was the means for collecting the ratings and rankings given by faculty members at selected Brazilian graduate programs. A questionnaire using Likerttype and ranking items asked the importance attributed by each respondent to each of the 109 items listed. The data analysis reported in this dissertation indicates that the most highly rated criteria and indicators were: (1) Library: current periodicals; (2) Facilities: classrooms and laboratories; (3) Library: books and monographs; (4) Academic Environment: discussion, investigation, and expression; and (5) Facilities: research space and equipment. The study presents the means and standard deviations obtained for each indicator and also includes some figures obtained for a relational analysis. This dissertation was developed to provide useful information to educational planners, policy makers, administrators, and evaluators involved in Brazilian higher education or comparative studies. It is suggested that additional investigations concentrate on more specific and in-depth analysis and interpretation of the policymaking processes, i.e., on the study of social facts or organizational and academic variables in their relationships with aspects of the educational system. The appendices section includes a facsimile of the questionnaire and additional data.

European business schools and global leadership: an examination of the admission criteria of the european master in management programs ranked by the Financial Times 2010

O aumento de empresas que operam internacionalmente requer o desenvolvimento de líderes mundiais para colocar as estratégias em prática. Embora este processo de desenvolvimento é importante para o mundo corporativo, muitos futuros executivos são graduados de escolas de administração de empresas que estão intimamente ligados ao mundo de negócios e, portanto, desempenhão um papel importante no processo. Esta pesquisa examina se os programas europeus “Master in Management” classificado pelo Financial Times em 2010 selecionam aqueles candidatos que são mais adequados para o desenvolvimento de liderança global. Portanto, três anteriores meta-estudos são sintetizados para produzir um perfil de competências classificadas de um líder global. Então, informações sobre os critérios de admissão dos programas de mestrado são coletadas e comparadas com este perfil. Os resultados mostram que seis competências são medidas por mais da metade dos programas: proficiência em Inglês, capacidade analítica (racionamento lógico e quantitativo), capacidade de comunicação, conhecimento do negócio global, determinação para alcançar, motivação e capacidade interpessoal. Além disso, as habilidades operacionais requerentes pelos líderes globais não são significativas no processo de admissão e o foco é sobre as habilidades analíticas. Comparação dos resultados com o perfil anteriormente desenvolvido abrangente indica que uma quantidade significativa de programas pode subestimar o significado de habilidades pessoais e características para o desenvolvimento de líderes globais.

O que e o método científico: uma reflexão crítica sobre o método científico como subsídio para o ensino das ciências naturais

Ensinar ciência e, acima de tudo, ensinar o método científico e desenvolver a atitude crítica do estudante. Isto significa substituir a visão da ciência como uma coleção de fatos e teorias definitivamente estabelecidos, pela visão da ciência como um conhecimento racional - Porque crítico -, conjectural, provisório, sempre capaz de ser questionado e corrigido. Significa também opor à visão da ciência como uma representação completa e perfeita de fenômenos diretamente observáveis, a visão da ciência como uma reconstrução idealizada e parcial da realidade, que explica o visível pelo invisível. Nessa linha de raciocínio, devemos opor à idéia de uma observação pura e imparcial dos fatos, a ideia da observação guiada por hipóteses e teorias. Ensinar o meto do cientifico é questionar a ideia de que descobrimos e verificamos hipóteses através de procedimentos indutivos, substituindo-a pela ideia de que inventamos conjecturas ousadas, surgidas de nossa imaginação. Essas conjecturas, contudo, deverão ser testadas o mais severamente possível, através de tentativas de refutação que façam uso de experimentos controlados. No lugar da ilusória busca de teorias verificáveis, verdadeiras -ou pelo menos cada vez mais prováveis devemos buscar teorias de maior refutabilidade, cada vez mais amplas, precisas, profundas, de maior grau de corroboração e, talvez, mais próximas da verdade. Finalmente, ensinar o método científico significa também criticar cada uma das visões alternativas de ciência, propondo novos critérios para avaliar hipóteses e teorias científicas. É desnecessário dizer que estes critérios, por sua vez, devem também ser criticados, visto que a ausência de discussão crítica e a aceitação passiva e dogmática de um conjunto de ideias ou teorias e a não ciência, a pseudociência, enfim, a negação do espírito crítico e da racionalidade do homem.

Beneficiamentos da cinza de casca de arroz residual com vistas à produção de cimento composto e/ou pozolânico

A cinza de casca de arroz é um resíduo agro-industrial decorrente do processo de queima da casca de arroz, sendo largamente encontrada no Rio Grande do Sul, pois, historicamente, este Estado é o maior produtor de arroz no Brasil, com cerca de 45% da produção nacional. Empregada como fonte de energia, a casca de arroz é queimada em diversas empresas; algumas, devido à sua natureza, incorporam a cinza ao produto, mas a maioria não encontra outro destino que não o descarte em forma de aterro, criando, assim, um problema ambiental de poluição do solo, do ar e de rios e córregos. No entanto, devido à presença de elevado percentual de sílica (SiO2) na sua constituição, a cinza de casca de arroz pode ter vários empregos. Na construção civil, pode ser empregada como pozolana, conforme vários estudos já vêm demonstrando. Porém, encontra restrições por motivos como sua cor escura, que confere aos cimentos, argamassas e concretos aos quais é adicionada, uma coloração também escura, e a falta de uniformidade apresentada em termos de características químicas e, principalmente, mineralógicas. A cor escura não é um problema de ordem técnica, mas estética e de aceitação no mercado. Já a composição mineralógica está associada à atividade pozolânica e a falta de uniformidade do material disponível implica na incerteza do grau de reatividade. Este trabalho teve o objetivo de verificar a viabilidade técnica do emprego de cinzas de casca de arroz residuais na confecção de cimentos Portland composto e/ou pozolânico, a partir de beneficiamentos das mesmas, que associam tratamentos físicos, químicos e/ou térmicos, os quais têm como finalidade reverter e/ou minimizar os aspectos negativos citados. Para tanto, foram empregadas três cinzas de casca de arroz, oriundas de diferentes processos de produção e com composições mineralógicas distintas. Após definidos os tratamentos a serem aplicados, através de seleção pelos critérios de cor e composição mineralógica, as cinzas tratadas foram avaliadas quanto à sua pozolanicidade, pelo Índice de Atividade Pozolânica (IAP) da NBR 5752 e também por um IAP alterado, proposto neste trabalho. A produção de cimentos com CCA beneficiada se deu a partir de um cimento base com substituição por CCA, em massa e em diferentes percentuais. Tais cimentos foram avaliados quanto à resistência à compressão, aos tempos de pega, à pozolanicidade e à expansibilidade a quente. A análise dos dados obtidos indica que os tratamentos propostos e/ou a associação deles resultam em beneficio no desempenho das cinzas, em pelo menos um dos vários aspectos considerados. A presente pesquisa permite concluir que as CCA residuais têm potencial para serem empregadas na produção de cimentos, tanto aquelas menos cristalinas, quanto as mais cristalinas. Para tanto, devem ser beneficiadas, sendo pelo menos submetidas a tratamento físico para redução de sua granulometria. Se outros objetivos forem pretendidos, como coloração clara, os tratamentos térmico ou químico podem ser empregados.

Is what you say what you do? Analyzing and comparing the effect of buyer-supplier relationship in the Brazilian and Chinese supplier selection criteria

Choosing properly and efficiently a supplier has been challenging practitioners and academics since 1960’s. Since then, countless studies had been performed and relevant changes in the business scenario were considered such as global sourcing, quality-orientation, just-in-time practices. It is almost consensus that quality should be the selection driver, however, some polemical findings questioned this general agreement. Therefore, one of the objectives of the study was to identify the supplier selection criteria and bring this discussion back again. Moreover, Dickson (1966) suggested existing business relationship as selection criterion, then it was reviewed the importance of business relationship for the company and noted a set of potential negative effects that could rise from it. By considering these side effects of relationship, this research aimed to investigate how the relationship could influence the supplier selection and how its harmful effects could affect the selection process. The impact of this phenomenon was investigated cross-nationally. The research strategy adopted was a controlled experiment via vignette combined with discrete choice analysis. The data collections were performed in China and Brazil. By examining the results, it could be drawn five major findings. First, when purchasers were asked to declare their supplier selection priorities, quality was stated as the most important independently of country and relationship. This result was consistent with diverse studies since 60’s. However, when purchasers were exposed to a multi-criteria trade-off situation, their actual selection priorities deviate from what they had declared. In the actual decision-making without influence of buyer-supplier relationship, Brazilian purchasers focused on price and Chinese buyers prioritized delivery then price. This observation reinforced some controversial prior studies of Verma & Pullman (1998) and Hirakubo & Kublin (1998). Second, through the introduction of the buyer-supplier relationship (operationalized via relational capital) in the supplier selection process, this research extended the existing studies and found that Brazilian buyers still focused on price. The relationship became just another criterion for supplier selection such as quality and delivery. However, from the Chinese sample, the results suggested that quality was totally discarded and the decision was majorly made through price and relationship. The third finding suggested that relational capital could legitimate the quality and sustainability of the supplier and replaces these selection criteria and made the decisional task less complex. Additionally, with the relational capital, the decision-makings were associated to few biases such as availability cognition, commitment, confirmatory and perceived biases. By analyzing the purchasers’ behavior, relational capital inducted buyers of both countries to relax in their purchasing requirements (quality, delivery and sustainability) leading to potential negative effects. In the Brazilian sample, the phenomenon of willing to pay a higher price for a lower quality offer demonstrated to be a potential counterproductive and suboptimal decision. Finally, the last finding was associated to the cultural effect on the buyers’ decisions. From the outcome, it is possible to observe that if a purchaser’s cultural background is more relation-oriented, the more he will tend to use relational capital as a decision heuristic, thus, the purchaser will be more susceptible to the potential relationship’s side effects

Alterações qualitativas em contratos de obra pública e a teoria econômica dos contratos incompletos : é possível construir um avião em pleno voo?

Não é de hoje que o país assiste à descoberta de incontáveis casos de desvios de recursos públicos ou mesmo à má gestão de contratos de obra pública que ocasionam, além de grave prejuízo ao Erário, danos à sociedade, muitas vezes desprovida da utilidade que seria proporcionada pelo pactuado. Essas condutas normalmente são ensejadas por projetos de engenharia que podem ser considerados meras peças de ficção, pois não representam o esforço correto para a execução do bem que se deseja construir. A Lei nº 8.666/93 permite a licitação com base em projeto básico, o que, segundo a atual onda de pensamento brasileira, seja da doutrina, dos órgãos de controle, do Poder Legislativo e até mesmo da mídia, é, de fato, um sério problema a ser enfrentado, pois a sua contratação dá margem a aditivos, entendidos como os grandes vilões das obras públicas. Por isso, o Tribunal de Contas da União vem decidindo no sentido de fortemente restringir a possibilidade de alteração contratual e, além disso, tem capitaneado projetos no Congresso Nacional que visam praticamente à extinção da empreitada por preço unitário, espécie contratual na qual o risco do projeto, ainda sem as definições necessárias, acaba por ser assumido pela Administração contratante, responsável pela elaboração, e não pelo seu executor. Contudo, no caso de obras complexas de infraestrutura, deve-se perquirir se essa postura, que pretende acabar com a margem decisória do gestor público quanto à extensão da incompletude do projeto básico - e, portanto, do objeto do contrato -, merece ser repensada, não com vistas a possibilitar os recorrentes danos, mas no caminho de uma melhor programação das ações estatais. Isso porque nessas hipóteses, a busca por todas as informações necessárias para a confecção do projeto a ser ao final executado, no momento da elaboração do edital, ou é muito custosa ou simplesmente não é possível. Assim, seria mais eficiente a contratação integrada, prevista na Lei do Regime Diferenciado de Contratação, na qual o risco do projeto pode se alocado ao contratado. Ocorre que, como existem restrições, nem sempre é viável esse caminho. Nessa ordem de ideias, deve-se encontrar uma solução para que o tradicional contrato de obra pública supere os seus graves problemas de incentivos. A proposta do presente trabalho é a introdução de um procedimento de tomada de decisão transparente, que confira segurança jurídica e amplo conhecimento da sociedade, além de livre acesso aos órgãos de controle, a partir de critérios não apenas jurídicos, mas econômicos e técnicos.

Significados e percepções do homem diante da gravidez de sua companheira com síndromes hipertensivas

The general aim of the research was to comprehend the Social Representations constructed by the man in the face of his companion s risk pregnancy caused by hypertensive syndromes. The study is of exploratory and descriptive character in a qualitative approach developed at two public maternity hospitals, both located in Natal-RN, with 65 men whose wives had undergone high-risk pregnancy. The project was submitted to the Ethics on Research Committee of the Federal University of Rio Grande do Norte, Brazil (CEP-UFRN), with favorable report no. 81/07. For data collection, the following multimethods were employed: a word free association test; a projective test for registering mental images; and a semistructured interview schedule. The speech contents were analyzed in accordance with the Theory of Social Representations and complemented by the Central Nucleus Theory. The discussion of the results was grounded on literary findings of the companion s participation in pregnancy as well as in risk pregnancy associated with hypertensive syndromes. The data showed fear as representation s central nucleus, while recollections of that feeling referred to death of both companion and child in addition to fear of the unknown. The categories preoccupation and carefulness, other feelings, and clinical picture of the disease represented components of the peripheral nucleus. The results concerning mental images followed the same category criteria of the word free association test fear, other feelings, preoccupation, carefulness, and clinical picture of the disease. After being processed in accordance with the principles of content analysis, the statements originated three thematic unities: fear and insecurity in the presence of the companion s risk pregnancy; attitudes of carefulness to the risk pregnancy of the partner; and humanized assistance during the companion s risk pregnancy. Considering the results, the conclusion is that the partner s risk pregnancy caused by hypertensive syndromes represents, for the man, feelings of fear, preoccupation, insecurity, lack of acceptance and information, as well as attitudes of carefulness. The results reveal necessity of reorganizing the obstetric assistance with an eye to including the man as participant in the reproductive process. That demands extension of humanized carefulness to the companion with a view to make him an active coadjutor in the assistance of high-risk pregnant

Criteria for analysis of the structure of electronic scientific journals

This paper is the result of the Masters dissertation studying the role and history of scientific communication, especially the changes that have occurred after the appearance of electronic communication and computer networks. This study showed that hypertext systems are increasingly being used in the scientific and academic world in the production of electronic journals; this makes it possible for the user to rapidly access information in their area. However, these systems need to be improved to help the user during search and access to information. Both printed journals migrating to electronic media, and the exclusively electronic journals should present the current quality indicators. The attempt was made to discover whether characteristics related to printed journals are being maintained in their electronic counterparts. For this, a prototype model was developed to analyze the structure of electronic scientific journals; it composes 14 criteria expressing aspects of quality for these journals. It includes elements of Website Information Architecture and those already in place in printed scientific journals in order to ensure that basic functions - archiving and dissemination - are maintained in electronic publishing. Each criterion consists of variables, which measure the maintenance of these functions both in the migrating printed journals and the exclusively electronic ones. This prototype model was used to analyze Ciência da Informação On-line and DataGramaZero - Revista de Ciência da Informação. Results indicate that this model is able to find out if the basic functions of archiving and dissemination are being maintained in electronic journals. Therefore, its implementation is justified in electronic journals. The model can help librarians, authors, and users of electronic journals to identify quality journals, and assist editors in developing their projects. The material from the study may be included in the preservice and inservice education of Information Science professionals and to support editors of scientific journals.

A função social do contrato como concretização de direitos fundamentais nas relações privadas

This dissertation deals with the social function of the contract, based on constitutional principles, especially those relating to fundamental rights. The social function of the contract (general clause) is described in the Civil Code so intentionally generic, no precise criteria to define it. Because of the fluidity of this principle, it is justified its closer study, seeking to assess its various meanings and looking away from the legal uncertainty that an unlimited conceptual vagueness can cause. The social function of the contract arises from a transformation experienced in private law from the inflows received from the Constitutional Law, the result of an evolutionary process by which it became the state structure, leaving the foundations of the classical liberal state and moving toward a vision guided by existential human values that give the keynote of the Welfare State. Arose, then the concern about the effectiveness of fundamental rights in relations between individuals, which is studied from the inapplicability of fundamental rights in private relations (U.S. doctrine of State action), passing to the analysis of the Theory of indirect horizontal effect of fundamental rights (of German creation and majority acceptance), reaching the right horizontal efficacy Theory of fundamental rights, prevailing Brazilian doctrine and jurisprudence. It has also been investigated the foundations of the social contract, pointing out that, apart from the provisions of the constitutional legislation, that base the principle on screen, there have also been noticed foundations in the Federal Constitution, in devices like the art. 1, III, the dignity of the human person is the north of the relationship between contractors. Also art. 3rd, I CF/88 bases the vision of social covenants, equipping it for the implementation of social solidarity, as one of the fundamental objectives of the Republic. Still on art. 170 of the Constitution it is seen as a locus of reasoning in the social function of the contract, the maintenance of the economic order. It is also studied the internal and external aspects of the social function of the contract, being the first part the one that considers the requirement of respect for contractual loyalty, through the objective good faith, as a result of the dignity of the hirer may not be offended by the other through the contract. On the other hand, the external facet of the social function of the contract, in line with the constitutional mandate of solidarity, indicates the need for contractors to respect the rights of society, namely the diffuse, collective and individual third party. In this external appearance, it is also pointed the notion of external credit protection, addressing the duty of society to respect the contract. There has been shown some notions of the social contract in comparative law. Then, there has been investigated the content of principle study, through their interrelationships with other provisions of private and constitutional law, namely equality, objective good faith, private autonomy and dignity of the human person. We study the application of the social contract in contractual networks as well as the guidance of conservation of contracts, especially those denominated long-term captive contracts, considering the theory of substantive due performance, concluding with an analysis of the social contract in code of Consumer Protection

Comparison of selection criteria for pre-weaning growth traits of Nelore cattle

Genetic parameters were estimated for pre-weaning average daily gain (ADG) and number of days to gain 160 kg from birth to weaning (D 160) of Nelore cattle. Ranks of animals were compared for these traits. Heritability estimates were 0.17 and 0.10 for ADG (direct and maternal), and 0.14 and 0.09, for D 160 (direct and maternal). Rank correlations between expected breeding values (EBV) were 0.97 and 0.95, for direct and maternal effects, respectively. Despite similar heritability estimates and high rank correlations, results showed that changes in rank could happen when choosing the best animals according to EBV for D 160 or ADG. There were evidences that sires selected using D 160 would produce progeny that achieve a specified market weight at an earlier age and would be more uniform, since this criterion is calculated as a harmonic mean function.

Testicular traits as selection criteria for young Nellore bulls

The objective of this study was to evaluate the possible use of biometric testicular traits as selection criteria for young Nellore bulls using Bayesian inference to estimate heritability coefficients and genetic correlations. Multitrait analysis was performed including 17,211 records of scrotal circumference obtained during andrological assessment (SCAND) and 15,313 records of testicular volume and shape. In addition, 50,809 records of scrotal circumference at 18 mo (SC18), used as an anchor trait, were analyzed. The (co) variance components and breeding values were estimated by Gibbs sampling using the Gibbs2F90 program under an animal model that included contemporary groups as fixed effects, age of the animal as a linear covariate, and direct additive genetic effects as random effects. Heritabilities of 0.42, 0.43, 0.31, 0.20, 0.04, 0.16, 0.15, and 0.10 were obtained for SC18, SCAND, testicular volume, testicular shape, minor defects, major defects, total defects, and satisfactory andrological evaluation, respectively. The genetic correlations between SC18 and the other traits were 0.84 (SCAND), 0.75 (testicular shape), 0.44 (testicular volume), -0.23 (minor defects), -0.16 (major defects), -0.24 (total defects), and 0.56 (satisfactory andrological evaluation). Genetic correlations of 0.94 and 0.52 were obtained between SCAND and testicular volume and shape, respectively, and of 0.52 between testicular volume and testicular shape. In addition to favorable genetic parameter estimates, SC18 was found to be the most advantageous testicular trait due to its easy measurement before andrological assessment of the animals, even though the utilization of biometric testicular traits as selection criteria was also found to be possible. In conclusion, SC18 and biometric testicular traits can be adopted as a selection criterion to improve the fertility of young Nellore bulls.

Análise técnica e econômica do processo de obtenção de espaguetes com adição de farinha de trigo integral e farinha de linhaça

This work studies the fabrication of spaghetti through the process at high temperatures through the use of flour added to flour and flaxseed meal, with the aim of evaluating the final product quality and estimate the cost of production. The values of moisture, ash, protein, wet gluten, gluten index, falling number and grain of flour and mixtures to test to be the possible use in mass manufacturing and technological criteria for compliance with current legislation. Spaghetti noodles type were manufactured by adding 10% and 20% flour and 10% and 20% flaxseed meal with performance of physical-chemical, sensory and rheological properties of the products. Further analysis was performed on the product acceptance and estimation of production cost in order to create subsidies to enable the introduction of products with greater acceptance and economic viability in the market by the food industry. On the rheology of the product test was cooking the pasta, specifying the volume increase, cooking time and percentage of solid waste. In the sensory evaluation was carried out the triangular test of product differentiation with 50 trained judges and acceptance testing by a hedonic scale with evaluation of the aspects color, taste, smell and texture. In defining the sensory profile of the product was performed with ADQ 9 judges recruited and trained at the factory, using unstructured scale of 9 cm, assessing the attributes of flavor of wheat, flax flavor, consistency, texture of raw pasta, raw pasta color and color of cooked pasta. The greater acceptance of product quality was good and the pasta with 20% flour, 10% followed by the full product, 10% and 20% flaxseed characterized the average quality of the criterion of loss analysis of solids, together with mass full commercial testing. In assessing the estimated cost of production, the two products more technologically feasible and acceptable (20% whole and 10% flaxseed) were evaluated in high temperature processes. With total cost of R $ 4,872.5 / 1,000 kg and R $ 5,354.9 / 1,000 kg respectively, the difference was related to the addition of lower inputs and higher added value in the market, flour and flaxseed meal. The comparative analysis of cases was confirmed the reduction in production time (10h), more uniform product to the drying process at high temperature compared to conventional

SENSORY ACCEPTANCE of JUICE FROM FCOJ PROCESSING STEPS

The acceptance of orange juice from the frozen concentrated orange juice (FCOJ) processing steps was evaluated by 101 consumers for color, overall impression, aroma, flavor and texture. The juice from the extraction, filtration, concentration, cooling and blend steps was collected at the beginning and the end of the 2009 harvest period. The juice from the extraction and filtration steps showed higher acceptance means for overall impression, aroma and flavor, while the juice from the concentration, cooling and blend steps had acceptance lower than the cutoff score. The internal preference mapping showed that color discriminated the juice from the collection periods while texture allowed discrimination between the steps of extraction and of filtration. The acceptance of the orange juice was driven by the aroma and flavor. The sensory acceptance was successfully applied to evaluate change during the process and the difference between the orange juice from different steps of the FCOJ processing.
