Agency and animation: the performance of interactive game characters

As an animator and practice-based researcher with a background in games development, I am interested in technological change in the video game medium, with a focus on the tools and technologies that drive game character animation and interactive story. In particular, I am concerned with the issue of ‘user agency’, or the ability of the end user to affect story development—a key quality of the gaming experience and essential to the aesthetics of gaming, which is defined in large measure by its interactive elements. In this paper I consider the unique qualities of the video game1 as an artistic medium and the impact that these qualities have on the production of animated virtual character performances. I discuss the somewhat oppositional nature of animated character performances found in games from recent years, which range from inactive to active—in other words, low to high agency. Where procedural techniques (based on coded rules of movement) are used to model dynamic character performances, the user has the ability to interactively affect characters in real-time within the larger sphere of the game. This game play creates a high degree of user agency. However, it lacks the aesthetic nuances of the more crafted sections of games: the short cut-scenes, or narrative interludes where entire acted performances are mapped onto game characters (often via performance capture)2 and constructed into relatively cinematic representations. While visually spectacular, cut-scenes involve minimal interactivity, so user agency is low. Contemporary games typically float between these two distinct methods of animation, from a focus on user agency and dynamically responsive animation to a focus on animated character performance in sections where the user is a passive participant. We tend to think of the majority of action in games as taking place via playable figures: an avatar or central character that represents a player. However, there is another realm of characters that also partake in actions ranging from significant to incidental: non-playable characters, or NPCs, which populate action sequences where game play takes place as well as cut scenes that unfold without much or any interaction on the part of the player. NPCs are the equivalent to supporting roles, bit characters, or extras in the world of cinema. Minor NPCs may simply be background characters or enemies to defeat, but many NPCs are crucial to the overall game story. It is my argument that, thus far, no game has successfully utilized the full potential of these characters to contribute toward development of interactive, high performance action. In particular, a type of NPC that I have identified as ‘pivotal’3—those constituting the supporting cast of a video game—are essential to the telling of a game story, particularly in genres that focus on story and characters: adventure games, action games, and role-playing games. A game story can be defined as the entirety of the narrative, told through non-interactive cut-scenes as well a interactive sections of play, and development of more complex stories in games clearly impacts the animation of NPCs. I argue that NPCs in games must be capable of acting with emotion throughout a game—in the cutscenes, which are tightly controlled, but also in sections of game play, where player agency can potentially alter the story in real-time. When the animated performance of NPCs and user agency are not continuous throughout the game, the implication is that game stories may be primarily told through short movies within games, making it more difficult to define video games animation as a distinct artistic medium.

Empirical Evidence on Relationships between Ex Ante Innovation Pursuit and Post-M&A Performance in the Vietnamese M&A Industry, 2005-2012

This research aims to communicate new results of empirical investigations to learn about the relationship between determination of controlling an acquired firm’s capital, assets and brand versus its capability of innovation and ex post performance of the rising Vietnamese M&A industry in the 2005-2012 period. The analysis employs a categorical data sample, consisting of 212 M&A cases reported by various information sources, and performs a number of logistic regressions with significant results as follows. Firstly, the overall relationship between pre-M&A pursuit’s determination on acquiring resources and performance of the post-M&A performance is found significant. There exist profound effects of a ‘size matters’ strategy in M&A ex post performance. When there is an overwhelming ‘resources acquiring’ strategy, the innovation factor’s explanatory power becomes negligible. Secondly, for negative performance of post-M&A operations, the emphasis on both capital base and asset size, and the brand value at the time of the M&A pursuit is the major explanation in the post-M&A period. So does the absence of innovation as a goal in the pre-M&A period. These two insights together are useful in careful M&A planning. Lastly, expensive pre-M&A expenditures tend to adversely affect the post-M&A performance. As a general conclusion, this study shows that innovation can be an important factor to pursue in M&A transitions, together with the need to emphasize and find capable and willing human capital, rather than a capital base (equity or debt) and existing values of the acquired brands.

Where does energy R&D come from? Examining crowding out from energy R&D

Recent efforts to endogenize technological change in climate policy models demonstrate the importance of accounting for the opportunity cost of climate R&D investments. Because the social returns to R&D investments are typically higher than the social returns to other types of investment, any new climate mitigation R&D that comes at the expense of other R&D investment may dampen the overall gains from induced technological change. Unfortunately, there has been little empirical work to guide modelers as to the potential magnitude of such crowding out effects. This paper considers both the private and social opportunity costs of climate R&D. Addressing private costs, we ask whether an increase in climate R&D represents new R&D spending, or whether some (or all) of the additional climate R&D comes at the expense of other R&D. Addressing social costs, we use patent citations to compare the social value of alternative energy research to other types of R&D that may be crowded out. Beginning at the industry level, we find no evidence of crowding out across sectors-that is, increases in energy R&D do not draw R&D resources away from sectors that do not perform R&D. Given this, we proceed with a detailed look at alternative energy R&D. Linking patent data and financial data by firm, we ask whether an increase in alternative energy patents leads to a decrease in other types of patenting activity. While we find that increases in alternative energy patents do result in fewer patents of other types, the evidence suggests that this is due to profit-maximizing changes in research effort, rather than financial constraints that limit the total amount of R&D possible. Finally, we use patent citation data to compare the social value of alternative energy patents to other patents by these firms. Alternative energy patents are cited more frequently, and by a wider range of other technologies, than other patents by these firms, suggesting that their social value is higher. © 2011 Elsevier B.V.

Creativity and entrepreneurial efforts in an emerging economy

While much research has focused on entrepreneurship and creativity in developed economies, the notions of both topics are still embryonic in many emerging economies. This paper focuses on entrepreneurs in one such economy, Vietnam, to understand the perceptions of entrepreneurs about the role that innovation and creativity may play in their own entrepreneurial ventures and success. This is important because before reaping benefits from entrepreneurship, entrepreneurs need to decide when and on what conditions they start based on their calculations of required resources and predictions of likely outcomes. The research also sought to understand how "creativity," broadly applied ("innovation" and "creative performance") affects the ways that entrepreneurs think about and anticipate their own success and decisions. In essence, the study suggests that the higher the entrepreur’s creativity is, the more likely she or he is to start a new business and believe success will result. Future research could examine whether history, industry and geographic location matter in entrepreneurs’ perceptions as well as whether transition/emerging economies like Vietnam may have different views altogether about the two key concepts.

Alternativas Processuais e Valorização de Correntes da Refinaria de Matosinhos.

Evolução, ato ou efeito de evoluir, sequência de transformações, desenvolvimento progressivo. Se tudo à nossa volta se transforma, a indústria tem de acompanhar esse sistema evolutivo, tornando assim imprescindível alterar ou melhorar processos de produção quando estes não se enquadram com a realidade, ou porque o mercado se altera, ou porque as necessidades mudam, ou por simplesmente ser mais rentável. Sendo a Galp Energia uma empresa que se encontra sempre na vanguarda da evolução tecnológica, encontra no Departamento de Engenharia Química do Instituto Superior de Engenharia do Porto um aliado na procura do melhor modo de valorizar os seus produtos. A Refinaria de Matosinhos tem atualmente duas correntes de gasolina leve e uma de refinado que apresentam grande potencialidade de valorização. Parte destas correntes incorporam atualmente a pool de nafta química da refinaria que é vendida à Repsol Polímeros. O desafio que é proposto baseia-se em valorizar essas correntes através da sua isomerização aumentando o seu RON podendo então ter como fim a pool de gasolinas. Tirando partido da tecnologia disponível para este efeito são apresentados quatro cenários de possíveis soluções. Sendo os dois primeiros excluídos por violarem restrições impostas, o terceiro e quarto cenários foram analisados de um ponto de vista económico. O terceiro cenário conduz a gasolina leve da Fábrica de Aromáticos para a pool de gasolinas sem qualquer tratamento e a gasolina leve da Fábrica de Combustíveis continua a integrar a pool de nafta química. O refinado da Fábrica de Aromáticos será enviado para um splitter, sendo a corrente de topo destinada à pool de nafta química e a corrente de fundo enviada a um reator de isomerização, Isomalk-4SM, passando previamente por uma torre de argila de forma a assegurar que a restrição em teor de olefinas no reator não é violada. O efluente, com RON maior, integrará igualmente a pool de gasolinas. No quarto cenário a corrente de refinado da Fábrica de Aromáticos não sofre qualquer tratamento, continuando a alimentar a unidade de solventes, a gasolina leve da Fábrica de Aromáticos irá diretamente para a pool de gasolinas e a gasolina leve da Fábrica de Combustíveis passará pelo Isomalk-2SM para aumentar o índice de octanos garantido assim ter condições de integrar a pool de gasolinas. Dissertação de Mestrado em Engenharia Química Isomerização de Gasolina Leve O terceiro cenário apresenta um aumento de 4 576 773 € anuais nas receitas e o quarto alcança 11 333 982 € anuais. O investimento inicial total do terceiro cenário é de 28 821 608 € quando o quarto cenário carece de um investimento inicial de apenas 18 028 349 €. Quanto aos custos associados à implementação da unidade estes demonstram-se elevados, o terceiro cenário apresenta um custo de 23 133 429 € enquanto o do quarto cenário é de 13 998 797 €. O quarto cenário apresenta-se assim como a solução mais rentável para o objetivo desta dissertação.

Utilização da Nanotecnologia para o desenvolvimento sustentável na indústria agro-alimentar

O crescimento populacional esperado para os próximos anos conduzirá à necessidade de aumentar a produção agrícola de modo a satisfazer o aumento da procura. Nos últimos anos tem-se assistido a uma evolução tecnológica nos sistemas de produção que tem permitido aumentar a produtividade agrícola, por vezes à custa de elevados consumos de energia e com práticas nem sempre ambientalmente corretas. Os desafios que se colocam atualmente são no sentido de melhorar a conservação de recursos escassos, como o solo e a água, de aumentar a eficiência de uso de fatores de produção, de encontrar novas culturas, do desenvolvimento da biotecnologia, da diminuição dos consumos energéticos e de melhorar ainda mais as tecnologias associadas à produção. De maneira a responder aos desafios emergentes da procura por alimentos, da escassez de terrenos agrícolas aráveis bem como da existência de pragas de insetos e de ervas daninhas, os pesticidas tem vindo a ser usados com maior frequência, tendo-se assistido a uma contaminação dos solos e águas subterrâneas, causando deste modo um risco para a saúde dos seres vivos. Neste sentido, vários fabricantes de pesticidas estão a desenvolver novas formulações contendo pesticidas encapsulados em nanopartículas como modo de aumentar a sua solubilidade em água, biodisponibilidade, volatilidade, estabilidade e eficácia. tendo por objetivo um desenvolvimento sustentável. Neste trabalho, procedeu-se ao estudo do encapsulamento do herbicida Oxadiargil (5-terc-butil-3-[2,4-dicloro-5-(2-propiniloxi)fenil]-1,3,4-oxadiazol-2(3H)-ona) com a 2-hidroxipropil-β-ciclodextrina (HP-β-CD). O estudo da formação do complexo de inclusão Oxadiargil - HP-β-CD foi realizado em diferentes meios, água desionizada, tampão acetato pH = 3,46 e pH = 5,34 e tampão fosfato pH = 7,45, com o objetivo de determinar e comparar a sua constante de estabilidade. Verificou-se, em qualquer dos casos, a ocorrência de uma relação linear entre o aumento da solubilidade do Oxadiargil e o aumento da concentração de HP-β-CD, com um declive inferior a um, o que indicia a formação de um complexo na proporção estequiométrica de 1:1. Os resultados obtidos permitiram concluir que o processo de complexação Oxadiargil - HP-β-CD não é muito influenciado pela constituição e pelo pH do meio. De facto, as constantes de estabilidade obtidas para a água desionizada e soluções-tampão pH = 3,46, pH = 5,34 e pH = 7,45 foram de 919 ± 25, 685 ± 13, 623 ± 17 e 753 ± 9, respetivamente. A solubilidade do complexo obtido nos estudos realizados, em diferentes meios, é cerca de 23 a 32 vezes superior à observada para o Oxadiargil livre. De forma a caracterizar o complexo Oxadiargil - HP-β-CD procedeu-se à sua síntese utilizando o método de “kneading”. O composto obtido foi caracterizado por Ressonância Magnética Nuclear (RMN) tendo-se confirmado a formação de um complexo de inclusão na proporção estequiométrica de 1:1. O complexo obtido é mais solúvel e porventura mais estável quimicamente. O encapsulamento permite uma redução da aplicação dos pesticidas diminuindo assim os custos e o impacto negativo no ambiente. Com a nanotecnologia é possível a libertação controlada dos pesticidas, aumentando a sua eficácia e fornecendo os meios necessários para um desenvolvimento sustentável.

O Futuro dos Centros de Dados

Atualmente, as Tecnologias de Informação (TI) são cada vez mais vitais dentro das organizações. As TI são o motor de suporte do negócio. Para grande parte das organizações, o funcionamento e desenvolvimento das TI têm como base infraestruturas dedicadas (internas ou externas) denominadas por Centro de Dados (CD). Nestas infraestruturas estão concentrados os equipamentos de processamento e armazenamento de dados de uma organização, por isso, são e serão cada vez mais desafiadas relativamente a diversos fatores tais como a escalabilidade, disponibilidade, tolerância à falha, desempenho, recursos disponíveis ou disponibilizados, segurança, eficiência energética e inevitavelmente os custos associados. Com o aparecimento das tecnologias baseadas em computação em nuvem e virtualização, abrese todo um leque de novas formas de endereçar os desafios anteriormente descritos. Perante este novo paradigma, surgem novas oportunidades de consolidação dos CD que podem representar novos desafios para os gestores de CD. Por isso, é no mínimo irrealista para as organizações simplesmente eliminarem os CD ou transforma-los segundo os mais altos padrões de qualidade. As organizações devem otimizar os seus CD, contudo um projeto eficiente desta natureza, com capacidade para suportar as necessidades impostas pelo mercado, necessidades dos negócios e a velocidade da evolução tecnológica, exigem soluções complexas e dispendiosas tanto para a sua implementação como a sua gestão. É neste âmbito que surge o presente trabalho. Com o objetivo de estudar os CD inicia-se um estudo sobre esta temática, onde é detalhado o seu conceito, evolução histórica, a sua topologia, arquitetura e normas existentes que regem os mesmos. Posteriormente o estudo detalha algumas das principais tendências condicionadoras do futuro dos CD. Explorando o conhecimento teórico resultante do estudo anterior, desenvolve-se uma metodologia de avaliação dos CD baseado em critérios de decisão. O estudo culmina com uma análise sobre uma nova solução tecnológica e a avaliação de três possíveis cenários de implementação: a primeira baseada na manutenção do atual CD; a segunda baseada na implementação da nova solução em outro CD em regime de hosting externo; e finalmente a terceira baseada numa implementação em regime de IaaS.

A intervenção privada na prestação pública : da expansão do Estado às parcerias público-privadas

Durante séculos o papel do Estado na vida económica e social das nações foi crescendo, atingindo um desenvolvimento assinalável a partir da segunga guerra mundial, em execução do novo paradigma que dela resultou. Desenvolvimento que conheceu fortes críticas com paragem e posterior inversão de sentido durante a década de 80 em que se gerou alguma diluição da intervenção do Estado, criando-se um movimento de relativo cepticismo relativamente à bondade, à eficiência e aos custos daquela intervenção. Foi nesse contexto e paralelamente com o aumento da vontade de intervir do sector privado que surgiram as chamadas três «vagas» de intervenção privada, sucessivamente dirigidas às actividades públicas (i) em sectores industriais, comerciais ou de serviços não estratégicos, (ii) no domínio das infra-estruturas e, finalmente, (iii) na área social, recorrendo com diferentes níveis de sucesso, a diversos processos, da privatização às parcerias público-privadas (PPP), passando pela empresarialização. O movimento de reforma nascido de reservas quanto à eficiência do sector público não passou ao lado da saúde, particularmente do hospital público, em que assumiu objectivos e modos específicos, das «reformas de gestão» às «reformas de financiamento» e às «reformas organizacionais », para, na sequência do movimento anteriormente ocorrido noutros domínios, também recorrer às parcerias público-privadas. Depois de situar estas iniciativas no contexto do movimento que rodeou o aumento da intervenção privada na produção e na prestação pública, o artigo procura identificar os requisitos de compatibilidade das parcerias público-privadas com sistemas de saúde organizados e que perseguem a universalidade da cobertura, a acessibilidade e compreensividade dos cuidados e a equidade do acesso, com especial atenção ao facto de (designadamente em Portugal) a partilha de riscos e tarefas poder atribuir ao sector privado a gestão das dimensões clínicas da prestação.

The use of future-oriented knowledge in regional innovation processes: Research on knowledge generation, transfer and conversion

The importance of the regional level in research has risen in the last few decades and a vast literature in the fields of, for instance, evolutionary and institutional economics, network theories, innovations and learning systems, as well as sociology, has focused on regional level questions. Recently the policy makers and regional actors have also began to pay increasing attention to the knowledge economy and its needs, in general, and the connectivity and support structures of regional clusters in particular. Nowadays knowledge is generally considered as the most important source of competitive advantage, but even the most specialised forms of knowledge are becoming a short-lived resource for example due to the accelerating pace of technological change. This emphasizes the need of foresight activities in national, regional and organizational levels and the integration of foresight and innovation activities. In regional setting this development sets great challenges especially in those regions having no university and thus usually very limited resources for research activities. Also the research problem of this dissertation is related to the need to better incorporate the information produced by foresight process to facilitate and to be used in regional practice-based innovation processes. This dissertation is a constructive case study the case being Lahti region and a network facilitating innovation policy adopted in that region. Dissertation consists of a summary and five articles and during the research process a construct or a conceptual model for solving this real life problem has been developed. It is also being implemented as part of the network facilitating innovation policy in the Lahti region.

Management Material: Understanding the Contradictory Perspectives of Lower Level Managers in a Canadian Call Centre

Call centres have emerged during a time of rapid technological change and represent a form of ready employment for those seeking to replace or supplement "traditional" forms of employment. Call centre work is considered characteristic of the kinds of service work available in the new economy. This paper examines the experiences and practices of lower level managers in a call centre in southern Ontario. Findings are based on analysis of semi-structured interviews. The findings suggest that lower level managers resolve the contradictory social space they occupy by aligning themselves primarily with more powerful executives, in part because they know this might lead to increased job security. The implications of this trend for building a strong labour movement capable of combating neoliberal discourses regarding the need for work restructuring are discussed.

Vertical R&D Sprillovers, Cooperation, Market Structure, and Innovation.

This paper studies vertical R&D spillovers between upstream and downstream firms. The model incorporates two vertically related industries, with horizontal spillovers within each industry and vertical spillovers between the two industries. Four types of R&D cooperation are studied : no cooperation, horizontal cooperation, vertical cooperation, and simultaneous horizontal and vertical cooperation. Vertical spillovers always increase R&D and welfare, while horizontal spillovers may increase or decrease them. The comparison of cooperative settings in terms of R&D shows that no setting uniformly dominates the others. Which type of cooperation yields more R&D depends on horizontal and vertical spillovers, and market structure. The ranking of cooperative structures hinges on the signs and magnitudes of three competitive externalities (vertical, horizontal, and diagonal) which capture the effect of the R&D of a firm on the profits of other firms. One of the basic results of the strategic investment literature is that cooperation between competitors increases (decreases) R&D when horizontal spillovers are high (low); the model shows that this result does not necessarily hold when vertical spillovers and vertical cooperation are taken into account. The paper proposes a theory of innovation and market structure, showing that the relation between innovation and competition depends on horizontal spillovers, vertical spillovers, and cooperative settings. The private incentives for R&D cooperation are addressed. It is found that buyers and sellers have divergent interests regarding the choice of cooperative settings and that spillovers increase the likelihood of the emergence of cooperation in a decentralized equilibrium.
