The Orator (O Le Tulafale) was promoted as the first Samoan language film shot in Samoa with a Samoan cast and crew. Written and directed by Samoan filmmaker Tusi Tamasese, the film succeeded at several of the movie industry’s prestigious festivals. The Orator (O Le Tulafale) is about an outcast family of a dwarf (Saili), his wife and her teenage daughter. As the main protagonist, Saili battles to overcome his fears to become a chief to save his family and land. The film’s themes are courage, love, honour , as well as hypocrisy, violence, and discrimination. A backlash by Samoans was predicted ; however, the opposite occurred. This raised the following questions: first, what is it about the film causing this reaction? It is a 106 -minute film shot in Samoa about Samoans and the Samoan culture . D espite promotional claims about the film , there have been Samoan -produced films in Samoa . Secondly, to what are Samoans really responding? Is it 1) just to the film because it is about Samoa, or 2) are they responding to themselves , and how they reacted during the act of watching the film? This implies levels of reactions in the act of watching, and examining the dominant level of response is important. To explore this, t he Samoan story telling technique of Fāgogo was used to analyse the film’s narration and narrative techniques. R. Allen’s (1993, 1997) concept of projected illusion was employed to discuss the relationship between Samoans and the film developed during the act of watching. An examination of the term Samoan and a description of the framework of Fa’a Samoa (Samoan culture) were provided. Also included were discussions of memory and its impact on Samoan cultural identity. The analysis indicated that The Orator (O Le Tulafale) acted as a memory prompt through which Samoans recalled memories confirming and defining cultural bonds. These memories constituted the essence of being Samoan. These memories were awakened, and shared as oral histories as fāgogo. The receivers appeared to interpret the shared memories to create their own memories and stories to suit their contexts, according to Facebook postings. An interpretation is that the organic sharing of memories as fā gogo created a global definition of Samoan that Samoans internationally claimed.

Retailers tend to become trapped in a price-promotion war where price issues are dealt with on a short-term basis, indicating almost solely tactical choices. Since price is the only part of the marketing mix providing direct revenues to the organisation, it should also be of strategic importance for the retailer. Not only in practice are price tactics often separated from pricing strategies, it is also the case in research where these are often studied in isolation from each other probably due to their individual complexity. This paper contributes to both the research area and practice by discussing these two complex areas together, and the essence of both strategy and tactics are defined. By considering the planning horizon for the retailer this paper further contributes by defining the links between price strategy and price tactic. The conclusion shows the importance of clearly establishing which analytical level is being analysed.

Using genome-wide data from 253,288 individuals, we identified 697 variants at genome-wide significance that together explained one-fifth of the heritability for adult height. By testing different numbers of variants in independent studies, we show that the most strongly associated ∼2,000, ∼3,700 and ∼9,500 SNPs explained ∼21%, ∼24% and ∼29% of phenotypic variance. Furthermore, all common variants together captured 60% of heritability. The 697 variants clustered in 423 loci were enriched for genes, pathways and tissue types known to be involved in growth and together implicated genes and pathways not highlighted in earlier efforts, such as signaling by fibroblast growth factors, WNT/β-catenin and chondroitin sulfate-related genes. We identified several genes and pathways not previously connected with human skeletal growth, including mTOR, osteoglycin and binding of hyaluronic acid. Our results indicate a genetic architecture for human height that is characterized by a very large but finite number (thousands) of causal variants.2014

During the development of system requirements, software system specifications are often inconsistent. Inconsistencies may arise for different reasons, for example, when multiple conflicting viewpoints are embodied in the specification, or when the specification itself is at a transient stage of evolution. These inconsistencies cannot always be resolved immediately. As a result, we argue that a formal framework for the analysis of evolving specifications should be able to tolerate inconsistency by allowing reasoning in the presence of inconsistency without trivialisation, and circumvent inconsistency by enabling impact analyses of potential changes to be carried out. This paper shows how clustered belief revision can help in this process. Clustered belief revision allows for the grouping of requirements with similar functionality into clusters and the assignment of priorities between them. By analysing the result of a cluster, an engineer can either choose to rectify problems in the specification or to postpone the changes until more information becomes available.

In e-Science experiments, it is vital to record the experimental process for later use such as in interpreting results, verifying that the correct process took place or tracing where data came from. The process that led to some data is called the provenance of that data, and a provenance architecture is the software architecture for a system that will provide the necessary functionality to record, store and use process documentation. However, there has been little principled analysis of what is actually required of a provenance architecture, so it is impossible to determine the functionality they would ideally support. In this paper, we present use cases for a provenance architecture from current experiments in biology, chemistry, physics and computer science, and analyse the use cases to determine the technical requirements of a generic, technology and application-independent architecture. We propose an architecture that meets these requirements and evaluate a preliminary implementation by attempting to realise two of the use cases.

From where did this tweet originate? Was this quote from the New York Times modified? Daily, we rely on data from the Web but often it is difficult or impossible to determine where it came from or how it was produced. This lack of provenance is particularly evident when people and systems deal with Web information or with any environment where information comes from sources of varying quality. Provenance is not captured pervasively in information systems. There are major technical, social, and economic impediments that stand in the way of using provenance effectively. This paper synthesizes requirements for provenance on the Web for a number of dimensions focusing on three key aspects of provenance: the content of provenance, the management of provenance records, and the uses of provenance information. To illustrate these requirements, we use three synthesized scenarios that encompass provenance problems faced by Web users today.

Desenvolvimentos recentes na tecnologia de informação têm proporcionado grandes avanços no gerenciamento dos sistemas de transportes. No mundo já existem várias tecnologias testadas e em funcionamento que estão auxiliando na tarefa de controle da operação do transporte público por ônibus. Esses sistemas geram informações úteis para o planejamento e operação dos sistemas de transportes. No Brasil, os investimentos em tecnologias avançadas ainda são muito modestos e estão focados em equipamentos que auxiliam no controle da evasão da receita. No entanto, percebe-se um crescente interesse, por parte dos órgão gestores e operadores, em implementar sistemas automatizados para auxiliar na melhoria da qualidade dos sistemas de transportes e como forma de aumentar a produtividade do setor. Esse trabalho traz à discussão os sistemas avançados desenvolvidos para o transporte público coletivo, com o objetivo de definir o perfil da tecnologia avançada que está de acordo com as necessidades dos gestores e operadores brasileiros. Na realização do trabalho foi empregada uma ferramenta de planejamento denominada Desdobramento da Função Qualidade – QFD (Quality Function Deployment), bastante utilizada para direcionar os processos de manufatura e produto, e para hierarquizar os atributos considerados importantes para o gerenciamento do transporte público urbano no Brasil. O resultado do trabalho indica um grande interesse em implantar tecnologia avançada para auxiliar no monitoramento dos tempos de viagem e tempos perdidos durante a operação do transporte público. Essa tecnologia também é tida como capaz de melhorar o desempenho das linhas, através da manutenção da regularidade e pontualidade. Ainda, sistemas inteligentes que propiciam informações precisas aos usuários contribuem para melhorar a imagem do modal ônibus.

The discussion about corporate obligations toward the various stakeholders began in the postindustrial era and developed to culminate in the creation of rules, regulations, programs and projects focusing on the dissemination and promotion of what we know today as corporate social responsibility (CSR). In this context, satisfying this new demand and adopting social policies emerge as a determining factor in defining organizational strategies. Nevertheless, some questions are raised when we examine the subject, such as: To what extent should organizations intervene in society? Is the decision for the organizations to adopt a socially responsible attitude really linked to promoting social well being, or is it only a commercial strategy? How does social marketing relate to CSR projects? The study herein, based on the concept and understanding of CSR theories, stakeholders and social marketing, has sought to find evidence of this relationship, in the light of the Global Compact (GC). It was decided to use the multi-case study methodology, considering the possibility of explaining the reasons why the decisions were taken, how they were implemented and what was the outcome. Interviews, supported by previously prepared scripts, were held with CSR managers, employees from other areas of the organizations, and specialists on the subject. Complementary research studies were made in various sources, such as the website of companies under analysis, their sustainability reports, and the GC websites in Brazil and the United Nations (UN). The results obtained show that the organizations have worked increasingly with CSR projects, but the efforts have not been focused. Special mention is given to the programs that create major impact on the company¿s image and reputation, such as projects competing for prizes and participating in the formation of rankings or socially responsible organizations. From the view of Carroll¿s Pyramid (1991) for CSR, it is found that the projects are predominantly focusing on ethical and philanthropic issues. The driving power of the GC, action based on learning, dialogue and partnership, is not to be found. This factor contributes to the statement that social marketing tools are used to build an ethical and socially responsible image, in detriment to effective action by the organizations to meet the social requirements of their stakeholders. The social marketing has as an objective to transform the way a specific public sees a social question and promotes behavior changes, but what has been seen is the use of marketing tools exclusively to promote the company's image.

A partir do ano de 2000, o processo de internacionalização da China se intensificou e tornou ainda mais visível as diferenças culturais diante das perspectivas Ocidentais. Uma delas é a divergência entre as práticas de gestão e liderança. Baseada em uma revisão de literatura de 234 artigos publicados em periódicos com fator de impacto acima de 1.0, esta dissertação identifica como estudiosos definem liderança na China desde 2000 até hoje. Os resultados podem ser divididos em três grupos: perspectiva das Teorias Ocidentais, perspectiva das Teorias Orientais e perspectiva teorias combinadas onde os Estudos Interculturais e a Liderança Transformacional dominaram as perspectivas adotadas pelos pesquisadores (estes incluídos no grupo de perspectiva das Teorias Ocidentais). Na perspectiva das Teorias Orientais, o Confucionismo e o Guanxi foram os mais citados. Enquanto na perspectiva das Teorias Combinadas, Confucionismo e o Guanxi foram misturados com várias Teorias Ocidentais. Portanto, embora haja uma forte cultura local, a perspectiva mais adotada pelos periódicos internacionais e estudiosos para olhar a e analisar a liderança na China foram os Estudos Interculturais e a Liderança Transformacional.

Esse é um dos primeiros trabalhos a endereçar o problema de avaliar o efeito do default para fins de alocação de capital no trading book em ações listadas. E, mais especificamente, para o mercado brasileiro. Esse problema surgiu em crises mais recentes e que acabaram fazendo com que os reguladores impusessem uma alocação de capital adicional para essas operações. Por essa razão o comitê de Basiléia introduziu uma nova métrica de risco, conhecida como Incremental Risk Charge. Essa medida de risco é basicamente um VaR de um ano com um intervalo de confiança de 99.9%. O IRC visa medir o efeito do default e das migrações de rating, para instrumentos do trading book. Nessa dissertação, o IRC está focado em ações e como consequência, não leva em consideração o efeito da mudança de rating. Além disso, o modelo utilizado para avaliar o risco de crédito para os emissores de ação foi o Moody’s KMV, que é baseado no modelo de Merton. O modelo foi utilizado para calcular a PD dos casos usados como exemplo nessa dissertação. Após calcular a PD, simulei os retornos por Monte Carlo após utilizar um PCA. Essa abordagem permitiu obter os retornos correlacionados para fazer a simulação de perdas do portfolio. Nesse caso, como estamos lidando com ações, o LGD foi mantido constante e o valor utilizado foi baseado nas especificações de basiléia. Os resultados obtidos para o IRC adaptado foram comparados com um VaR de 252 dias e com um intervalo de confiança de 99.9%. Isso permitiu concluir que o IRC é uma métrica de risco relevante e da mesma escala de uma VaR de 252 dias. Adicionalmente, o IRC adaptado foi capaz de antecipar os eventos de default. Todos os resultados foram baseados em portfolios compostos por ações do índice Bovespa.

Customer participation has been studied for decades; however, it gained a postmodern perspective around the year 2000. Customers have become co-creators of personalized experiences, moving from the audience to the stage. In the educational context, students must take responsibility for their learning process and participate in the production of the service. This changing is providing opportunities and challenges for higher education institutions (HEIs) to redefine their relationship with stakeholders, especially with students. This study is based on the service dominant logic (SDL) perspective because students are assumed to take the role of co-creators of knowledge in the educational setting. The research uses adapted frameworks and concepts applied in organizational, knowledge-intensive business services (KIBS) and also medical studies to advance the understanding of value co-creation in the HEI context. The current study addresses a lack of research in the higher education context focusing on defining students’ participation and students’ empowerment in higher education context. An empirical investigation was developed with traditional schools in Brazil. This investigation allowed the description of the constructs in the specific context. The description of student participation in HEIs context reflects the relevance of three dimensions – information sharing, personal interaction and responsible behavior. In the Brazilian context, responsible behavior is the weakest dimension in the construct, because the responsibilities are unbalanced between students and professors. The main reasons identified for this unbalanced relation were cultural issues and local regulation. Student empowerment was described as composed by four dimensions – meaningfulness, competence, impact and choice; however, one of them – choice – was identified as the weakest dimension, facing cultural and bureaucratic barriers for implementation in the Brazilian educational context. Moreover, interviewees spontaneously cited the idea of trust in the faculty as an important antecedent of student participation that must be considered when analyzing student participation and empowerment mechanisms. An additional contribution was the proposal of a theory-based framework for understanding the service dominant logic perspective in the HEI context, in which student participation and student empowerment were explored as mechanisms leading to positive student behavior toward institution.
