Guia de desenvolvimento de jogos para programadores independentes

Os vídeo jogos ou jogos de computador têm vindo a crescer na sua relação com o público ganhando terreno e credibilidade nos benefícios que os jogadores obtêm quando usam este tipo de software, indo esses benefícios para além do divertimento associado à palavra jogo no seu sentido etimológico. Nos últimos anos cada vez mais o mercado e algumas das mais reputadas instituições de ensino têm dedicado especial atenção a este tipo de software, englobando nesses estudos diversas áreas desde a engenharia à saúde, incluindo ainda, estudos de cariz psicológico e sociológico reveladores de que estas experiências de entretenimento, cada vez mais disponíveis a todos, têm influência na sua envolvente de integração e relação com outros fenómenos de cariz social. Apreciado o estado da arte esta tese tem como principal objetivo servir de guia de iniciação a individuais ou pequenas equipas da área de desenvolvimento de software no caminho para o desenvolvimento de jogos de vídeo independentes, apresentando uma análise cuidada capaz de apoiar as equipas desde o momento zero, estando o mesmo estruturado de forma a refletir o entendimento das bases teóricas em que o desenvolvimento deste tipo de software assenta, o estado da arte sobre plataformas, análise de mercado e indústria, metodologias de desenvolvimento e equipas, e ainda analisadas algumas das mais relevantes ferramentas de desenvolvimento e criação de conteúdos. Como prova de conceito e componente de caráter experimental, este trabalho compreende ainda o desenvolvimento de um jogo de vídeo guiado pelas orientações e lições apreendidas durante o processo de estudo de forma a ser representativo da aplicação dessa aprendizagem, e ainda capaz de detalhar passo a passo cada fase do processo, com o objetivo de apoiar a preparação de pessoas interessadas em iniciar a aventura de desenvolver os seus próprios jogos e quem sabe dar início aos seus próprios negócios e empresas. O jogo desenvolvido replica um recente êxito, o jogo 2048, que apesar da sua mecânica simples revela-se um excelente desafio do ponto de vista da sua implementação, bem como o processo criativo adjacente no transformar algo tão simples e experimentado numa experiência nova capaz de atrair antigos jogadores e interesse de novos. O desenvolvimento e publicação da aplicação experimental, e após análise dos dados recolhidos, mostram-se reveladores de que é de fato possível a programadores independentes entrar num mercado de alto potencial, e que adquiridas as bases de conhecimento expostas no documento estarão em condições mais favoráveis para ultrapassar algumas das mais comuns barreiras no atingir desse objetivo.

Lack of Spontaneous Venous Pulsation: Possible Risk Indicator in Normal Tension Glaucoma?

PURPOSE: Recently, the absence of spontaneous venous pulsation (SVP) has been suggested as a vascular risk factor for primary open-angle glaucoma (POAG). As the mechanism behind this phenomenon is still unknown, the authors have studied this vascular component using colour Doppler imaging (CDI). METHODS: A total of 236 patients were divided into three diagnostic groups: healthy controls (81), POAG (86) and normal tension glaucoma (NTG; 69). All subjects were submitted to CDI studies of the retrobulbar circulation, intraocular pressure measurements and assessment of SVP existence. Mann-Whitney, chi-square contingency tables and Spearman correlations were used to explore differences and correlations between variables in the diagnostic groups. RESULTS: Eighty-two percent of healthy controls had SVP (66/81), while a smaller numbers were registered in both glaucoma groups: POAG - 50% (43/86); NTG - 51% (35/69). In NTG patients, but not in POAG patients, the prevalence of the SVP phenomenon decreases with increased glaucoma damage (p = 0.04; p = 0.55, respectively). Overall glaucoma patients from both groups had lower central retinal vein (CRV) velocities than the healthy controls (p < 0.05). NTG patients with SVP had less severe visual field defects (mean defect -6.92 versus -11.1, p < 0.05), higher [correction added after online publication 21 September 2012; the word 'higher' has been inserted to replace the word 'lower'] peak systolic and mean flow velocities in the central retinal artery (p < 0.01; p < 0.05, respectively) as well as higher [correction added after online publication 21 September 2012; the word higher has been inserted to replace the word lower] maximal velocities and RI of the CRV (p < 0.02; p < 0.05, respectively). CONCLUSIONS: Glaucoma patients have a decrease in CRV velocities. SVP is less prevalent in glaucoma patients than in healthy individuals. This phenomenon apparently reflects different hemodynamic patterns in the central retinal vessels. This variable may be of particular importance in NTG patients, where it may be associated with more advanced functional damage.

Mansfield and Lewis: impressionism and vorticism in the short story

The affinities of the short story with the style of painting dominating the period in which it is produced have often been debated by critics. The effects of the application of impressionist and vorticist principles in painting turns out differently in Katherine Mansfield and Wyndham Lewis’ short stories structure and strategies, according to their conceptions of Art and Life and to his career as a painter.

Lá fora um lugar para existir/Abroad a place where to exist

A exposição “Artistas Portugueses - Lá Fora” pretende mostrar uma parte significativa da produção de artes plásticas que resultou de processos de migração que tiveram origem em território português. Integra uma multiplicidade de situações temporais e sociais que, para serem lidas, necessitam de alguma contextualização. Trata-se, tal como no caso da emigração económica, de uma emigração de sobrevivência, sendo que aqui o sentido do termo sobrevivência assume uma dimensão mais existencial. Para elas, partir quer dizer, ao mesmo tempo, resistir enquanto ser humano e existir enquanto criador. The exhibition “ABROAD” aims to show a significant part of the Fine Arts production resulting from migration procedures starting from the Portuguese territory. It comprises multiple periods of time and social situations which, in order to be comprehended, need to be contextualized. This is, just like in the case of economic emigration, an emigration for survival even if in this context the meaning of the Word survival assumes an existential dimension. For those people to leave means, simultaneously, to resist as a human being and to exist as a creator.

Res Publica: Citizenship and Political Representation in Portugal, 1820-1926

The term res publica (literally “thing of the people”) was coined by the Romans to translate the Greek word politeia, which, as we know, referred to a political community organised in accordance with certain principles, amongst which the notion of the “good life” (as against exclusively private interests) was paramount. This ideal also came to be known as political virtue. To achieve it, it was necessary to combine the best of each “constitutional” type and avoid their worst aspects (tyranny, oligarchy and ochlocracy). Hence, the term acquired from the Greeks a sense of being a “mixed” and “balanced” system. Anyone that was entitled to citizenship could participate in the governance of the “public thing”. This implied the institutionalization of open debate and confrontation between interested parties as a way of achieving the consensus necessary to ensure that man the political animal, who fought with words and reason, prevailed over his “natural” counterpart. These premises lie at the heart of the project which is now being presented under the title of Res Publica: Citizenship and Political Representation in Portugal, 1820-1926. The fact that it is integrated into the centenary commemorations of the establishment of the Republic in Portugal is significant, as it was the idea of revolution – with its promise of rupture and change – that inspired it. However, it has also sought to explore events that could be considered the precursor of democratization in the history of Portugal, namely the vintista, setembrista and patuleia revolutions. It is true that the republican regime was opposed to the monarchic. However, although the thesis that monarchy would inevitably lead to tyranny had held sway for centuries, it had also been long believed that the monarchic system could be as “politically virtuous” as a republic (in the strict sense of the word) provided that power was not concentrated in the hands of a single individual. Moreover, various historical experiments had shown that republics could also degenerate into Caesarism and different kinds of despotism. Thus, when absolutism began to be overturned in continental Europe in the name of the natural rights of man and the new social pact theories, initiating the difficult process of (written) constitutionalization, the monarchic principle began to be qualified as a “monarchy hedged by republican institutions”, a situation in which not even the king was exempt from isonomy. This context justifies the time frame chosen here, as it captures the various changes and continuities that run through it. Having rejected the imperative mandate and the reinstatement of the model of corporative representation (which did not mean that, in new contexts, this might not be revived, or that the second chamber established by the Constitutional Charter of 1826 might not be given another lease of life), a new power base was convened: national sovereignty, a precept that would be shared by the monarchic constitutions of 1822 and 1838, and by the republican one of 1911. This followed the French example (manifested in the monarchic constitution of 1791 and in the Spanish constitution of 1812), as not even republicans entertained a tradition of republicanism based upon popular sovereignty. This enables us to better understand the rejection of direct democracy and universal suffrage, and also the long incapacitation (concerning voting and standing for office) of the vast body of “passive” citizens, justified by “enlightened”, property- and gender-based criteria. Although the republicans had promised in the propaganda phase to alter this situation, they ultimately failed to do so. Indeed, throughout the whole period under analysis, the realisation of the potential of national sovereignty was mediated above all by the individual citizen through his choice of representatives. However, this representation was indirect and took place at national level, in the hope that action would be motivated not by particular local interests but by the common good, as dictated by reason. This was considered the only way for the law to be virtuous, a requirement that was also manifested in the separation and balance of powers. As sovereignty was postulated as single and indivisible, so would be the nation that gave it soul and the State that embodied it. Although these characteristics were common to foreign paradigms of reference, in Portugal, the constitutionalization process also sought to nationalise the idea of Empire. Indeed, this had been the overriding purpose of the 1822 Constitution, and it persisted, even after the loss of Brazil, until decolonization. Then, the dream of a single nation stretching from the Minho to Timor finally came to an end.
