In most e-learning scenarios, communication and on-line collaboration is seen as an add-on feature to resource based learning. This paper will endeavour to present a pedagogical framework for inverting this view and putting communities of practice as the basic paradigm for e-learning. It will present an approach currently being used in the development of a virtual Radiopharmacy community, called VirRAD, and will discuss how theory can lead to an instructional design approach to support technologically enhanced learning.(DIPF/Orig.)

Over the last few years, more and more heuristic decision making techniques have been inspired by nature, e.g. evolutionary algorithms, ant colony optimisation and simulated annealing. More recently, a novel computational intelligence technique inspired by immunology has emerged, called Artificial Immune Systems (AIS). This immune system inspired technique has already been useful in solving some computational problems. In this keynote, we will very briefly describe the immune system metaphors that are relevant to AIS. We will then give some illustrative real-world problems suitable for AIS use and show a step-by-step algorithm walkthrough. A comparison of AIS to other well-known algorithms and areas for future work will round this keynote off. It should be noted that as AIS is still a young and evolving field, there is not yet a fixed algorithm template and hence actual implementations might differ somewhat from the examples given here.

Considerando a gravação de 1947 The Bud Powell Trio como a gravação referência de trio de piano de jazz moderno, esta tese centra-se no surgimento e evolução do trio de jazz moderno cujo líder é pianista. Começando por apresentar, uma resenha dos estilos e técnicas para piano de da época pre-Powell, esta tese investiga a génese dos trios de piano jazz e examina três dos mais influeciais pianostas de jazz e lideres dos mais legendários trios de piano jazz modernos: Bud Powell, Bill Evans e Keith Jarrett. Esta tese também abordará o paradoxo inerente a um sistema democrático - a expressão própria do individuo, em justaposição com a responsabilidade para com o todo – e a sua inequivoca analogia com o gestalt do trio de piano de jazz moderno. Desde a primeira gravação de um trio de jazz com pianista como líder em 1935, o trio de jazz moderno, evoluiu tornando-se um exemplo de democracia – um contexto de igualdade em que as funções rítmicas, harmónicas, e melódicas estão igualmente distribuídas entre os três instrumentistas, que são ao mesmo tempo solistas e acompanhadores. Esta tese sublinha a eficácia do trio de jazz moderno – o seu início, e porque subsiste – baseado na sua força e beleza estética; ABSTRACT: THE TWENTIETH CENTURY JAZZ PIANO TRIO – The Rise of an Iconic Jazz Paradigm by Susan Muscarella Designating Bud Powell’s 1947 recording, The Bud Powell Trio, as the modern jazz piano trio benchmark, here, this thesis traces the emergence and evolution of the pianistled, piano-bass-drums-comprised modern jazz piano trio. Beginning with a general overview of pre-Powell jazz piano styles and techniques, this thesis investigates the earliest, most salient pre-Powell jazz piano trios, and examines three seminal modern jazz pianists and leaders of legendary modern jazz piano trios, Bud Powell, Bill Evans and Keith Jarrett. This thesis also brings to the fore the paradox inherent in a democratic system – individual self-expression juxtaposed with responsibility to the whole – and its unequivocal analogy to the modern jazz piano trio gestalt. From the earliest recording of a primarily piano-dominated piano-bass-drums-comprised jazz piano trio in 1935, the modern jazz piano trio has evolved to become a paragon of democracy – an egalitarian playing field in which rhythmic, harmonic and melodic roles are evenly distributed among all three instrumentalists who have come to serve as both soloists and accompanists.

The class of all locally quasi-convex (lqc) abelian groups contains all locally convex vector spaces (lcs) considered as topological groups. Therefore it is natural to extend classical properties of locally convex spaces to this larger class of abelian topological groups. In the present paper we consider the following well known property of lcs: “A metrizable locally convex space carries its Mackey topology ”. This claim cannot be extended to lqc-groups in the natural way, as we have recently proved with other coauthors (Außenhofer and de la Barrera Mayoral in J Pure Appl Algebra 216(6):1340–1347, 2012; Díaz Nieto and Martín Peinador in Descriptive Topology and Functional Analysis, Springer Proceedings in Mathematics and Statistics, Vol 80 doi:10.1007/978-3-319-05224-3_7, 2014; Dikranjan et al. in Forum Math 26:723–757, 2014). We say that an abelian group G satisfies the Varopoulos paradigm (VP) if any metrizable locally quasi-convex topology on G is the Mackey topology. In the present paper we prove that in any unbounded group there exists a lqc metrizable topology that is not Mackey. This statement (Theorem C) allows us to show that the class of groups satisfying VP coincides with the class of finite exponent groups. Thus, a property of topological nature characterizes an algebraic feature of abelian groups.

This talk, which is based on our newest findings and experiences from research and industrial projects, addresses one of the most relevant challenges for a decade to come: How to integrate the Internet of Things with software, people, and processes, considering modern Cloud Computing and Elasticity principles. Elasticity is seen as one of the main characteristics of Cloud Computing today. Is elasticity simply scalability on steroids? This talk addresses the main principles of elasticity, presents a fresh look at this problem, and examines how to integrate people, software services, and things into one composite system, which can be modeled, programmed, and deployed on a large scale in an elastic way. This novel paradigm has major consequences on how we view, build, design, and deploy ultra-large scale distributed systems.

Pre-exposure prophylaxis" (PrEP) has been recently developed as a prevention strategy which involves the administration of drugs to non-infected individuals who present high exposure or susceptibility to HIV. Although this use is not approved in our country, several guidelines recommend PrEP as a prevention option in adult MSM, heterosexual men and women, and users of parenteral drugs at risk of acquiring the infection. This article presents the characteristics that an ideal agent to be used as PrEP should meet, recent efficacy published data and barriers for the implementation of this new strategy. On the other hand, the role of hospital pharmacists will be discussed.

One of the aspects related to biolaw is that related to security and health. In other words, using the expression of relevant authorities on this subject, “the securitization of health” and, those situations connected with the Security Council labour in the last decades, may constitute an interesting subject. Beginning with the role of the UN blue helmets in many countries where the expansion of HIV/AIDS is usual, followed by the expansion of some diseases in Haiti, together with the Ebola “crisis” in 2014 and connected with the efforts of the World Health Organization to fight against the zika...what is the role played by the United Nations Security Council on this field, trying to establish a relationship between security and health?

Let me begin this commentary by suggesting that many of the ideas contained in this special issue will be important to the future of correctional psychology. Although each of the authors offer different perspectives on the role that the criminal justice system has to play in the process of desistance from crime, they all identify the importance of a valueoriented analysis to effective offender rehabilitation. Their focus is on promoting desistance at all points of the justice process; from how the legal system can promote therapeutic outcomes through to the provision of post-release support services and the need for community engagement. By approaching the tasks of both rehabilitation and reintegration from a values perspective, they have been able to identify a range of novel and innovative approaches that have the potential to make a real difference. Even more encouragingly, these draw on resources that may already be available to correctional psychologists and yet are often underutilized. In addition, the confidence, and indeed the optimism, expressed in these articles provides a refreshing counter to suggestions that contemporary correctional practice has become pre-occupied with the need to “manage” offenders and for professionals to focus on fulfilling their administrative obligations (see Hardy, 2014).

Fog Computing is a paradigm that extends Cloud computing and services to the edge of the network. Similar to Cloud, Fog provides data, compute, storage, and application services to end-users. In this article, we elaborate the motivation and advantages of Fog computing, and analyse its applications in a series of real scenarios, such as Smart Grid, smart traffic lights in vehicular networks and software defined networks. We discuss the state-of-the-art of Fog computing and similar work under the same umbrella. Security and privacy issues are further disclosed according to current Fog computing paradigm. As an example, we study a typical attack, man-in-the-middle attack, for the discussion of security in Fog computing. We investigate the stealthy features of this attack by examining its CPU and memory consumption on Fog device.
