Os espectadores de cinema em Portugal nos últimos 40 anos: o caso da cidade de Bragança

O número de espetadores de cinema tem variado ao longo dos tempos. Nos últimos 40 anos, em Portugal, o sentido é globalmente descendente devido sobretudo à internet e às novas tecnologias de comunicação. Esta informação pode ser comprovada com os números fornecidos pela base de dados “ Pordata” e por alguns estudos realizados nesta área. O cinema é uma arte em constante mudança e que influencia a sociedade, mas é ao mesmo tempo influenciado por ela, constituindo mesmo o seu autorretrato. Sem a interação com a sociedade contemporânea a sétima arte não evolui nem desperta paixões. Este facto pode determinar os altos e baixos na história do cinema

Arginine vasotocin regulation of interspecific cooperative behaviour in a cleaner fish

In an interspecific cooperative context, individuals must be prepared to tolerate close interactive proximity to other species but also need to be able to respond to relevant social stimuli in the most appropriate manner. The neuropeptides vasopressin and oxytocin and their non-mammalian homologues have been implicated in the evolution of sociality and in the regulation of social behaviour across vertebrates. However, little is known about the underlying physiological mechanisms of interspecific cooperative interactions. In interspecific cleaning mutualisms, interactions functionally resemble most intraspecific social interactions. Here we provide the first empirical evidence that arginine vasotocin (AVT), a non-mammalian homologue of arginine vasopressin (AVP), plays a critical role as moderator of interspecific behaviour in the best studied and ubiquitous marine cleaning mutualism involving the Indo-Pacific bluestreak cleaner wrasse Labroides dimidiatus. Exogenous administration of AVT caused a substantial decrease of most interspecific cleaning activities, without similarly affecting the expression of conspecific directed behaviour, which suggests a differential effect of AVT on cleaning behaviour and not a general effect on social behaviour. Furthermore, the AVP-V1a receptor antagonist (manning compound) induced a higher likelihood for cleaners to engage in cleaning interactions and also to increase their levels of dishonesty towards clients. The present findings extend the knowledge of neuropeptide effects on social interactions beyond the study of their influence on conspecific social behaviour. Our evidence demonstrates that AVT pathways might play a pivotal role in the regulation of interspecific cooperative behaviour and conspecific social behaviour among stabilized pairs of cleaner fish. Moreover, our results suggest that the role of AVT as a neurochemical regulator of social behaviour may have been co-opted in the evolution of cooperative behaviour in an interspecific context, a hypothesis that is amenable to further testing on the potential direct central mechanism involved.

Amateurism and the Aesthetics of Lego Stop-Motion on YouTube

Do the “democratization” of media and the proliferation of online participatory culture undermine the aesthetic hegemony of professional filmmakers? This article is a case study of both more and less popular animated Lego videos, also called “brickfilms,” that asks how amateur videos adhere to and/or depart from professionalized aesthetic standards. It addresses the definitions of professionalism and amateurism and proposes that the dichotomy between democratization and ongoing elitism is insufficient to describe the complex dialogue between professional film aesthetics and amateur production—a dialogue that is diverse but nonetheless follows certain patterns. These patterns link Lego videos to silent era cinema as well as contemporary professional live-action and stop-motion animation. Furthermore, a mixture of parody, pastiche, and homage suggest that amateur work has a variety of affective relationships to professional work. Ultimately, amateur filmmaking indicates a negotiation of professional standards rather than slavish adherence.

Graphic satire and public life in the age of terror

This paper investigates media representations of international insecurity through a selection of newspaper cartoons from some of the major daily Australian broadsheets. Since 2001, cartoonists such as Bruce Petty, John Spooner and Bill Leak (in The Age and The Australian) have provided an ongoing and vehement critique of the Australian government’s policies of ‘border protection’, the ‘war on terror’ and the words of mass distraction associated with Australia joining the war in Iraq. Cartoonists are often said to represent the ‘citizen’s perspective’ of public life through their graphic satire on the editorial pages of our daily newspapers. Increasingly, they can also be seen to be fulfilling the role of public intellectuals, defined by Richard A. Posner as ‘someone whose place it is publicly to raise embarrassing questions, to confront orthodoxy and dogma, to be someone who cannot easily be co-opted by governments and corporations’. Cartoonists enjoy an independence and freedom from censorship that is rarely extended to their journalistic colleagues in the print media and it is this independence that is the vital component in their being categorised as public intellectuals. Their role is to ‘question over and over again what is postulated as self-evident, to disturb people’s mental habits, to dissipate what is familiar and accepted, to re-examine rules and institutions’ (Posner, 2003: 31). With this useful — if generalised — definition in mind, the paper considers how cartoonists have contributed to debates concerning international insecurity in public life since 2001.

The functions of societies and the evolution of group living: Spider societies as a test case

Many models have been advanced to suggest how different expressions of sociality have evolved and are maintained. However these models ignore the function of groups for the particular species in question. Here we present a new perspective on sociality where the function of the group takes a central role. We argue that sociality may have primarily a reproductive, protective, or foraging function, depending on whether it enhances the reproductive, protective or foraging aspect of the animal's life (sociality may serve a mixture of these functions). Different functions can potentially cause the development of the same social behaviour. By identifying which function influences a particular social behaviour we can determine how that social behaviour will change with changing conditions, and which models are most pertinent. To test our approach we examined spider sociality, which has often been seen as the poor cousin to insect sociality. By using our approach we found that the group characteristics of eusocial insects is largely governed by the reproductive function of their groups, while the group characteristics of social spiders is largely governed by the foraging function of the group. This means that models relevant to insects may not be relevant to spiders. It also explains why eusocial insects have developed a strict caste system while spider societies are more egalitarian. We also used our approach to explain the differences between different types of spider groups. For example, differences in the characteristics of colonial and kleptoparasitic groups can be explained by differences in foraging methods, while differences between colonial and cooperative spiders can be explained by the role of the reproductive function in the formation of cooperative spider groups. Although the interactions within cooperative spider colonies are largely those of a foraging society, demographic traits and colony dynamics are strongly influenced by the reproductive function. We argue that functional explanations help to understand the social structure of spider groups and therefore the evolutionary potential for speciation in social spiders.

Don't talk about me . . . like I'm not here: Disability in Australian national cinema

The article analyzes the representation of disability in Australian national cinema. Disability has been an enduring topic in Australian films and it has got occasional mentions in film and cultural criticism. An important pioneering treatment in this field is film critic Elizabeth Ferrier's examination of the trope of creative disabilities. Ferrier draws attention to disability in Australian film. She provides a stimulating and nuanced reading in light of the thematics of Australian cultural anxieties. "My One Legged Dream Lover," is one of the few productions that features a disabled lead character, Kath Duncan, played by disabled performer, Kath Duncan.

Levinas and the defination of philosophy: An ethical approach

Emmanuel Levinas’ thought seems to be strictly neither rational, phenomenological nor ontological, and it thus intentionally exposes itself to the asking of the question ‘why call it philosophy at all’? While we may have trouble containing Levinas’ thought within our traditional philosophical boundaries, I argue that this gives us no reason to exclude him from philosophy proper as a mere poser, but rather provides the occasion for reflection on just what it means, in an ethical manner, to call something ‘philosophical’. Instead of asking whether or not philosophy can ‘contain’ Levinas’ thought, I contend that it would be more ethical to instead re-phrase the question in terms of ‘sociality’. When we do this, I argue, we can indeed justifiably call Levinas’ thought philosophy.
