Libraries and Canon-Formation: the Case of English in the Collections of the Library of the Faculty of Humanities, Lisbon University

Abstract: The project for researching the role played by libraries in canon-formation (namely through their policies regarding the creation, organization, preservation, and utilization of the collections) will be presented and discussed. We selected the Library of the Faculty of Humanities, Lisbon University, a modern academic library, created in 1859, by royal decree of D. Pedro V, following his canonical choice. Actually, the two contemporary rulers of new Britannia— Prince Albert, his cousin, and Queen Victoria—held this king in high consideration for his outstanding contribution to Portuguese modernisation. Representing various fields of study, the collections were decisive to canon-formation in the Faculty of Humanities. Thus, we have been trying to answer the following questions: who has been creating, organizing, preserving, and utilizing the collections, from the mid-nineteenth century onwards? When, where and how? Presently, we are studying the collections in English, namely the works belonging or referring to the long nineteenth century. Richard Garnett’s “The International Library of Famous Literature” (London, 1899) is our first case-study. The anthology determined the Western literary, cultural and visual canon at the turning of the century, as evidenced by comparing it to the Portuguese and Spanish editions, published at the beginning of the twentieth century.

Complex Interplay Between Determinants of Pacing and Performance During 20 km Cycle Time Trials

Purpose This study examined the determinants of pacing strategy and performance during self paced maximal exercise. Methods Eight well trained cyclists completed two 20 km time trials. Power output, RPE, positive and negative affect, and iEMG activity of the active musculature were recorded every 0.5km, confidence in achieving pre-exercise goals was assessed every 5 km, and blood lactate and pH were measured post-exercise. Differences in all parameters were assessed between fastest (FAST) and slowest (SLOW) trials performed. Results Mean power output was significantly higher during the initial 90% of FAST, but not the final 10%, and blood lactate concentration was significantly higher and pH significantly lower following FAST. Mean iEMG activity was significantly higher throughout SLOW. RPE was similar throughout both trials, but participants had significantly more positive affect and less negative affect throughout FAST. Participants grew less confident in their ability to achieve their goals throughout SLOW. Conclusions The results suggest that affect may be the primary psychological regulator of pacing strategy and that higher levels of positivity and lower levels of negativity may have been associated with a more aggressive strategy during FAST. Although the exact mechanisms through which affect acts to influence performance are unclear, it may determine the degree of physiological disruption that can be tolerated, or be reflective of peripheral physiological status in relation to the still to be completed exercise task.

The modified Max-Log-MAP turbo decoding algorithm by extrinsic information scaling for wireless applications

The iterative nature of turbo-decoding algorithms increases their complexity compare to conventional FEC decoding algorithms. Two iterative decoding algorithms, Soft-Output-Viterbi Algorithm (SOVA) and Maximum A posteriori Probability (MAP) Algorithm require complex decoding operations over several iteration cycles. So, for real-time implementation of turbo codes, reducing the decoder complexity while preserving bit-error-rate (BER) performance is an important design consideration. In this chapter, a modification to the Max-Log-MAP algorithm is presented. This modification is to scale the extrinsic information exchange between the constituent decoders. The remainder of this chapter is organized as follows: An overview of the turbo encoding and decoding processes, the MAP algorithm and its simplified versions the Log-MAP and Max-Log-MAP algorithms are presented in section 1. The extrinsic information scaling is introduced, simulation results are presented, and the performance of different methods to choose the best scaling factor is discussed in Section 2. Section 3 discusses trends and applications of turbo coding from the perspective of wireless applications.

The world without outside

The world is all that there is. In the world, ontology and epistemology coincide. The thing and the perspective are part of it, scale is ingested in its multiplicity, communication stops at the world's edge. By reading together Deleuze and Guattari's plane of immanence and Niklas Luhmann's proto-global concept of Weltgesellschaft (“world society”), I suggest a conceptualisation of the world as the materiality of the multiple spaces of creation in an insular, all-inclusive immanence. Deprived of an outside, the world pushes its own understanding of circumference through, first, the expansion of its own limits through the process of worlding, and, second, the multiplication of modes of material (self-)production through its process of othering. Thus, the world swells up from the inside and expands on both the material and the semantic level, producing a multiplicity of fractal microcosms. Issues of responsibility and justice arise that are intricately linked to the materiality of the world and take place in and between the various bodies and spaces of the world but without an overarching hierarchy or principle. This approach is a way of counteracting the all-pervasive Hegelian understanding of synthesis, arguing instead for a plenitude that brims with positivity and that can never become fully complete. The world remains its own infinite process of worlding.

The Data of Things: Strategies, Patterns and Practice of Cloud-based Participatory Sensing

The broad capabilities of current mobile devices have paved the way for Mobile Crowd Sensing (MCS) applications. The success of this emerging paradigm strongly depends on the quality of received data which, in turn, is contingent to mass user participation; the broader the participation, the more useful these systems become. However, there is an ongoing trend that tries to integrate MCS applications with emerging computing paradigms such as cloud computing. The intuition is that such a transition can significantly improve the overall efficiency while at the same time it offers stronger security and privacy-preserving mechanisms for the end-user. In this position paper, we dwell on the underpinnings of incorporating cloud computing techniques to facilitate the vast amount of data collected in MCS applications. That is, we present a list of core system, security and privacy requirements that must be met if such a transition is to be successful. To this end, we first address several competing challenges not previously considered in the literature such as the scarce energy resources of battery-powered mobile devices as well as their limited computational resources that they often prevent the use of computationally heavy cryptographic operations and thus offering limited security services to the end-user. Finally, we present a use case scenario as a comprehensive example. Based on our findings, we posit open issues and challenges, and discuss possible ways to address them, so that security and privacy do not hinder the migration of MCS systems to the cloud.

On the 'inherent' character of the right of states to self-defence

While there is no lack of studies on the use of armed force by states in self-defence, its qualification as an ‘inherent right’ in article 51 of the Charter of the United Nations has received little scholarly attention and has been too quickly dismissed as having no significance. The present article fills this gap in the literature. Its purpose is not to discuss the limits to which article 51 or customary international law submit the exercise of the right of self-defence by states, but to examine what its 'inherent’ character means and what legal consequences it entails. The article advances two main arguments. The first is that self-defence is a corollary of statehood as presently understood because it is essential to preserving its constitutive elements. The second argument is that the exercise of the right of self-defence must be distinguished from the right itself: it is only the former that may be delegated to other states or submitted to limitations under customary international law and treaty law. The right of self-defence, however, cannot be alienated and it takes precedence over other international obligations, although not over those specifically intended to limit the conduct of states in armed conflict or over non-derogable human rights provisions.
