Segurança Nacional : «buzzword» ou conceito básico?

A reflexão que se apresenta tem por principal finalidade objetivar o conceito de «segurança», em quadro pintado em conjunto pelas Relações Internacionais e pela Estratégia. A existência de um designado «Conceito Estratégico de Defesa Nacional» alavanca o pensamento exposto, cumulativamente forçado à tradução da amarra traduzida pelo binómio «Segurança e Defesa» e, deta forma, concretizar também um entendimento de «defesa». Para a consecução das finalidades procurou tirar-se partido do conhecimento existente para construir ou dar a conhecer, com as devidas limitações impostas pela atividade enquadrante, uma construção teórica coerente e, como tal facilitadora de ação e prática inteligíveis.

Museologial process : exclusion criteria

In the last few years, reflections around knowledge building in the museology area have increased considerably, allowing us to cast many gazes over our actions, and, consequently, enabling us to a wider debate around our professional action field, decreasing our exclusion from the academic environment – museologists reproducing the knowledge produced in other areas. In the present work, we shall approach some issues related to the museological process, taking as a reference several studies about the subject, which, due to the time given to us in this round table, could not be re-presented here for discussion. Besides, we have dedicated a chapter to such approach in our publication titled “Museological Process and Education: building a didactic-community museum”. So we have opted instead to carry out a reflection about exclusion, looking into the museum institution and into the application of museological processes; in other words, we shall carry out a self-criticism, in which I include myself, affecting an analysis that will be debated here, considering, additionally, that the museums and museological practices are in relation to the other social global practices, therefore, they are the result of human relations at each historical moment. Finally, based on our lived experience, we shall give continuity to our reflection process, highlighting the importance of knowledge production for the area of museology and the relevance of the theory-practice relation, punctuating some aspects we think that may contribute to the construction of a museological action that may serve as a historical elaboration in securing a space for self- determination.

Destierro y redención: el «síndrome de Adán y Eva» en La belleza del mundo de Héctor Tizón (Crítica)

En este ensayo, el autor plantea un diálogo entre la novela La belleza del mundo, de Héctor Tizón, y los arquetipos bíblicos de Adán y Eva, la pérdida del paraíso y el destierro, y el retorno al Edén. A partir de la traición primigenia de la esposa del protagonista, se inicia la integración a un tiempo cíclico e infinito –el del exilio. En el destierro, el protagonista está marcado por su afán de anular la temporalidad real y, a la vez, su propia identidad, intenta forzosamente olvidar la propia historia, lo cual lo conduce a una crisis de identidad. Al cabo de un largo recorrido, se plantea la necesidad de incorporar los acontecimientos de la vida a un tiempo mítico que regenere y perpetúe todas las acciones, y en el cual se busque el sufrimiento para alcanzar la salvación. El autor evidencia paralelismos diversos del texto con la doctrina cristiana: el protagonista comprende que para regresar a su propio centro debe perdonar. Y eso solo es posible regresando, enfrentando su pasado: el tiempo de redención es un regreso, pero el mismo-nuevo sitio no vuelve a ser jamás el paraíso.

Denominaciones territoriales agroalimentarias, políticas y gestión social: Argentina, Brasil y la experiencia española en el contexto europeo

This article examines the conceptual framework and the institutional context of the Geographical Indications and Social Management in Spain on the European Union space. Then, providing a comparative study, Argentina’s and Brazil’s cases are analyzed. The emphasis is on identity and territorial development, where family farming has a central role. Thereafter, public policy drawings and implementation are projected in order to strength concrete agenda and measures elaboration based on Spanish and European experiences’. In both the Argentinean and Brazilian cases, the conclusions point to the need of an adjustment on public policies to better situate and implement actions and objectives. In Brazil the disclosure, financing and strengthening of the Geographical Indications should be bounded to the Programa Territórios da Cidadania, linked to the Ministério do Desenvolvimento Agrário, which is the place of the family farming strengthening policies. In Argentina, with the same logic, the actions should be situated on the Programa Nacional de Apoyo al Desarrollo de los Territórios.

View-based approaches to spatial representation in human vision

In an immersive virtual environment, observers fail to notice the expansion of a room around them and consequently make gross errors when comparing the size of objects. This result is difficult to explain if the visual system continuously generates a 3-D model of the scene based on known baseline information from interocular separation or proprioception as the observer walks. An alternative is that observers use view-based methods to guide their actions and to represent the spatial layout of the scene. In this case, they may have an expectation of the images they will receive but be insensitive to the rate at which images arrive as they walk. We describe the way in which the eye movement strategy of animals simplifies motion processing if their goal is to move towards a desired image and discuss dorsal and ventral stream processing of moving images in that context. Although many questions about view-based approaches to scene representation remain unanswered, the solutions are likely to be highly relevant to understanding biological 3-D vision.

'Does this compromise your design?' Interactionally producing a design concept in talk

How a design concept was interactionally produced in the talk-in-interaction between an architect and client representatives was studied. The empirical analysis was informed by ethnomethodology and conversation analysis to observe structures and patterns of talk that accomplished actions and practices of design. Some differences were observed between the properties of the design concept in comparison with the design ideas that were considered during these conversations. The design concept was observed to be significant for assessing why some moves in a design space were considered better than others. The importance of the design concept to these interactions raised more general questions about what a design concept is and how it can be described as an object type. With reference to studies of science, technology and society these concerns were provisionally engaged with and further study of the object properties of design concepts is suggested.

Interceptive timing: prior knowledge matters

Fast interceptive actions, such as catching a ball, rely upon accurate and precise information from vision. Recent models rely on flexible combinations of visual angle and its rate of expansion of which the tau parameter is a specific case. When an object approaches an observer, however, its trajectory may introduce bias into tau-like parameters that render these computations unacceptable as the sole source of information for actions. Here we show that observer knowledge of object size influences their action timing, and known size combined with image expansion simplifies the computations required to make interceptive actions and provides a route for experience to influence interceptive action.

Stimulus-driven selection of routes to imitation

Several models have proposed that an action can be imitated via one of two routes: a direct visuospatial route, which can in principle mediate imitation of both meaningful (MF) and meaningless (ML) actions, and an indirect semantic route, which can be used only for MF actions. The present study investigated whether selection between the direct and indirect routes is strategic or stimulus driven. Tessari and Rumiati (J Exp Psychol Hum Percept Perform 30:1107–1116, 2004) have previously shown, using accuracy measures, that imitation of MF actions is superior to imitation of ML actions when the two action types are presented in separate blocks, and that the advantage of MF over ML items is smaller or absent when they are presented in mixed blocks. We first replicated this finding using an automated reaction time (RT), as well as accuracy, measure. We then examined imitation of MF and ML actions in the mixed condition as a function of the action type presented in the previous trial and in relation to the number of previous test trials. These analyses showed that (1) for both action types, performance was worse immediately after ML than MF trials, and (2) even at the beginning of the mixed condition, responding to MF actions was no better than responding to ML items. These results suggest that the properties of the action stimulus play a substantial role in determining whether imitation is mediated by the direct or the indirect route, and that effects of block composition on imitation need not be generated through strategic switching between routes.

Peripersonal space: a multisensory interface for body-object interactions

Research in the last four decades has brought a considerable advance in our understanding of how the brain synthesizes information arising from different sensory modalities. Indeed, many cortical and subcortical areas, beyond those traditionally considered to be ‘associative,’ have been shown to be involved in multisensory interaction and integration (Ghazanfar and Schroeder 2006). Visuo-tactile interaction is of particular interest, because of the prominent role played by vision in guiding our actions and anticipating their tactile consequences in everyday life. In this chapter, we focus on the functional role that visuo-tactile processing may play in driving two types of body-object interactions: avoidance and approach. We will first review some basic features of visuo-tactile interactions, as revealed by electrophysiological studies in monkeys. These will prove to be relevant for interpreting the subsequent evidence arising from human studies. A crucial point that will be stressed is that these visuo-tactile mechanisms have not only sensory, but also motor-related activity that qualifies them as multisensory-motor interfaces. Evidence will then be presented for the existence of functionally homologous processing in the human brain, both from neuropsychological research in brain-damaged patients and in healthy participants. The final part of the chapter will focus on some recent studies in humans showing that the human motor system is provided with a multisensory interface that allows for continuous monitoring of the space near the body (i.e., peripersonal space). We further demonstrate that multisensory processing can be modulated on-line as a consequence of interacting with objects. This indicates that, far from being passive, the monitoring of peripersonal space is an active process subserving actions between our body and objects located in the space around us.

Exploring social barriers to adaptation: insights from Western Nepal

As the challenges and opportunities posed by climate change become increasingly apparent, the need for facilitating successful adaptation and enhancing adaptive capacity within the context of sustainable development is clear. With adaptation high on the agenda, the notion of limits and barriers to adaptation has recently received much attention within both academic and policymaking spheres. While emerging literature has been quick to depict limits and barriers in terms of natural, financial, or technologic processes, there is a clear shortfall in acknowledging social barriers to adaptation. It is against such a backdrop that this paper sets out to expose and explore some of the underlying features of social barriers to adaptation, drawing on insights from two case studies in the Western Nepal. This paper exposes the significant role of cognitive, normative and institutional factors in both influencing and prescribing adaptation. It explores how restrictive social environments can limit adaptation actions and influence adaptive capacity at the local level, particularly for the marginalised and socially excluded. The findings suggest a need for greater recognition of the diversity and complexity of social barriers, strategic planning and incorporation at national and local levels, as well as an emphasis on tackling the underlying drivers of vulnerability and social exclusion.

Prebiotics in foods

A wealth of information has been gathered over the past 15 years on prebiotics through experimental, animal and human studies, with the aim to understand the mechanism of actions and elucidate their beneficial health effects to the human host. Significant amount of evidence exists for their ability to increase the bioavailability of minerals and stimulate the immune system, although there is less clear evidence so far for their prophylactic or therapeutic role in gastrointestinal infections. Moreover, the effect of the food delivery vehicle on the efficacy of prebiotics is an area that has been hardly investigated. Besides their beneficial effects, prebiotics influence the textural and organoleptic properties of the food products, such as dairy and baked products. To do this however, they need to be stable during food processing, in particular under conditions of high temperature and low pH.

Reduced cortico-motor facilitation in a normal sample with high traits of autism

Recent research in social neuroscience proposes a link between mirror neuron system (MNS) and social cognition. The MNS has been proposed to be the neural mechanism underlying action recognition and intention understanding and more broadly social cognition. Pre-motor MNS has been suggested to modulate the motor cortex during action observation. This modulation results in an enhanced cortico-motor excitability reflected in increased motor evoked potentials (MEPs) at the muscle of interest during action observation. Anomalous MNS activity has been reported in the autistic population whose social skills are notably impaired. It is still an open question whether traits of autism in the normal population are linked to the MNS functioning. We measured TMS-induced MEPs in normal individuals with high and low traits of autism as measured by the autistic quotient (AQ), while observing videos of hand or mouth actions, static images of a hand or mouth or a blank screen. No differences were observed between the two while they observed a blank screen. However participants with low traits of autism showed significantly greater MEP amplitudes during observation of hand/mouth actions relative to static hand/mouth stimuli. In contrast, participants with high traits of autism did not show such a MEP amplitude difference between observation of actions and static stimuli. These results are discussed with reference to MNS functioning.

The embodied use of the material home: an affordance approach

This paper examines the relationship between embodied individuals and the home that they inhabit. Although there has been some work on both the embodied practices in the home and on the material nature of the home itself, this has not been integrated with the majority of research on home which has focused on meaning. It is argued that there is a lack of a unifying framework that can incorporate both use and meaning elements of home. A way of incorporating these elements through adoption of the concept of affordances is put forward. However, the affordance approach needs to be developed to achieve this. The paper does this first by incorporating the concept of intentionality of actions and then through the use of the concept of well‐being. Debates about housing for people with a physical disability and the practical help provided to this group of people are used to illustrate how the approach could work.

When consent doesn't work: a rights-based case for limits to consent’s capacity to legitimise

Consent's capacity to legitimise actions and claims is limited by conditions such as coercion, which render consent ineffective. A better understanding of the limits to consent's capacity to legitimise can shed light on a variety of applied debates, in political philosophy, bioethics, economics and law. I show that traditional paternalist explanations for limits to consent's capacity to legitimise cannot explain the central intuition that consent is often rendered ineffective when brought about by a rights violation or threatened rights violation. I argue that this intuition is an expression of the same principles of corrective justice that underlie norms of compensation and rectification. I show how these principles can explain and clarify core intuitions about conditions which render consent ineffective, including those concerned with the consenting agent's option set, his mental competence, and available information.

Are clinical documents optimised for patient safety? A critical analysis of patient safety outcomes using the EDA error model

Iatrogenic errors and patient safety in clinical processes are an increasing concern. The quality of process information in hardcopy or electronic form can heavily influence clinical behaviour and decision making errors. Little work has been undertaken to assess the safety impact of clinical process planning documents guiding the clinical actions and decisions. This paper investigates the clinical process documents used in elective surgery and their impact on latent and active clinical errors. Eight clinicians from a large health trust underwent extensive semi- structured interviews to understand their use of clinical documents, and their perceived impact on errors and patient safety. Samples of the key types of document used were analysed. Theories of latent organisational and active errors from the literature were combined with the EDA semiotics model of behaviour and decision making to propose the EDA Error Model. This model enabled us to identify perceptual, evaluation, knowledge and action error types and approaches to reducing their causes. The EDA error model was then used to analyse sample documents and identify error sources and controls. Types of knowledge artefact structures used in the documents were identified and assessed in terms of safety impact. This approach was combined with analysis of the questionnaire findings using existing error knowledge from the literature. The results identified a number of document and knowledge artefact issues that give rise to latent and active errors and also issues concerning medical culture and teamwork together with recommendations for further work.
