The Security Challenges for the 2016 Rio de Janeiro Olympic Games

Brazilians greeted the long-awaited decision of making Rio de Janeiro the host of the 2016 Olympic Games with tremendous exhilaration. Although Rio’s fantastic natural beauty certainly added to its attraction in hosting the games, its alarming rates of urban crime and violence largely associated with drug trafficking immediately triggered worldwide criticism, and put at issue its ability to guarantee the security for the games. Brazilians have been vying for a position as an emerging global economy and understand the importance of the Games for international prestige. This makes the stakes very high when hosting the Olympic Games in the wake of the 2014 Soccer World Cup, which will also be held in Brazil. This paper explores these criticisms and assesses Rio’s ability to prepare for this important event. The paper further explores the consensus that Brazilians will be more equipped to address actions taken by organized crime capable of affecting the Olympic Games than to face a terrorist attack. Brazil – and Rio – does not figure in the “terrorism map” as a region particularly linked to terrorism. Aside from uncorroborated suspicions of activities by terrorist organizations on the Tri-Border region (Argentina, Brazil, and Paraguay), Brazil does not elicit many concerns regarding terrorism.1 Yet, there is no way to guarantee that terrorist organizations will not try to make use of the 2016 Rio Olympic Games to advance their agenda. This being in mind, Rio and Brazil in general face a long road ahead to prepare, prevent, protect and respond to a possible terrorist attack during the 2016 Olympics. It is clear that prevention and preparation towards potential threats to the Games must necessarily include cooperation and exchange of best practices with other countries. 1 U.S. Department of State has confirmed that this area may have been used to transport weapons and conduct financial affairs in the past. This type of activity has been made more difficult with the fortification of border controls in more recent times.

Discharge measurements and storm event chemistry at the San Francisco River station (Planta) in 2007-2008

To improve our knowledge of the influence of land-use on solute behaviour and export rates in neotropical montane catchments we investigated total organic carbon (TOC), Ca, Mg, Na, K, NO3 and SO4 concentrations during April 2007-May 2008 at different flow conditions and over time in six forested and pasture-dominated headwaters (0.7-76 km2) in Ecuador. NO3 and SO4 concentrations decreased during the study period, with a continual decrease in NO3 and an abrupt decrease in February 2008 for SO4. We attribute this to changing weather regimes connected to a weakening La Niña event. Stream Na concentration decreased in all catchments, and Mg and Ca concentration decreased in all but the forested catchments during storm flow. Under all land-uses TOC increased at high flows. The differences in solute behaviour during storm flow might be attributed to largely shallow subsurface and surface flow paths in pasture streams on the one hand, and a predominant origin of storm flow from the organic layer in the forested streams on the other hand. Nutrient export rates in the forested streams were comparable to the values found in literature for tropical streams. They amounted to 6-8 kg/ha/y for Ca, 7-8 kg/ha/y for K, 4-5 kg/ha/y for Mg, 11-14 kg/ha/y for Na, 19-22 kg/ha/y for NO3 (i.e. 4.3-5.0 kg/ha/y NO3-N) and 17 kg/ha/y for SO4. Our data contradict the assumption that nutrient export increases with the loss of forest cover. For NO3 we observed a positive correlation of export value and percentage forest cover.

Implementing restorative justice practice in schools: what pedagogy reveals

In the ongoing pursuit for creating safe, nurturing and relational school cultures, educators continue to turn to restorative justice (rj) principles and practice. Predominantly, schools begin to engage with rj in an effort to address harm done, causing its discourse to be situated in literature tied to classroom management and behaviour. However, in this location, the effectiveness of rj can be limited because the power relationships underlying the original punitive, managerial structures maintain their grip. Drawing on a qualitative study that examines the experiences of educators committed to implementing rj principles, this article explores how placing rj in the context of engaged, productive pedagogies better nurtures the hoped for relational and peaceful school culture.

Theory games

This paper examines the remarkable and unexplored correspondence between games (and board games in particular) and what is commonly understood as theory in the social sciences. It argues that games exhibit many if not most of the attributes of theory, but that theory is missing some of the features of games. As such, game provide a way of rethinking what we mean by theory and theorizing. Specifically, games and their relationship with the ‘real’ world, provide a way of thinking about theory and theorizing that is consistent with recent calls to frame social inquiry around the concept of phrónēsis.

Westminster Serious Games Platform (wmin-SGP) a tool for real-time authoring of roleplay simulations for learning

The use of serious games in education and their pedagogical benefit is being widely recognized. However, effective integration of serious games in education depends on addressing two big challenges: the successful incorporation of motivation and engagement that can lead to learning; and the highly specialised skills associated with customised development to meet the required pedagogical objectives. This paper presents the Westminster Serious Games Platform (wmin-SGP) an authoring tool that allows educators/domain experts without games design and development technical skills to create bespoke roleplay simulations in three dimensional scenes featuring fully embodied virtual humans capable of verbal and non-verbal interaction with users fit for specific educational objectives. The paper presents the wmin-SGP system architecture and it evaluates its effectiveness in fulfilling its purpose via the implementation of two roleplay simulations, one for Politics and one for Law. In addition, it presents the results of two types of evaluation that address how successfully the wmin-SGP combines usability principles and game core drives based on the Octalysis gamification framework that lead to motivating games experiences. The evaluation results shows that the wmin-SGP: provides an intuitive environment and tools that support users without advanced technical skills to create in real-time bespoke roleplay simulations in advanced graphical interfaces; satisfies most of the usability principles; and provides balanced simulations based on the Octalysis framework core drives. The paper concludes with a discussion of future extension of this real time authoring tool and directions for further development of the Octalysis framework to address learning.

British Romantic Criticism and the Fine Arts: A Study in Philosophical Theories of Literary Unity

This dissertation is an exploration of how a small but important group of Romantic critics, finding fault in the ideal of three unities developed by neoclassical Academicians and wrongly attributed to Aristotle, turned to the terminology and practices of the fine arts to emphasize their conception of organic unity in literature. The Romantic analogy to painting in particular enables a philosophical criticism of literature to present the aesthetic semblance of painting, the comprehension of a multitude of details in a harmonious whole that is a natural unity to its medium, as a paradigm of modern-romantic poetry and its aspirations to similar complexity, particularity, and imaginative colour. Further, in extension of the French Querelle des anciens et des modernes of the seventeenth century, the division of ancient and romantic art by Romantic critics like August Schlegel, Samuel Taylor Coleridge, and William Hazlitt not only establishes an ethnological and historical difference between the artistic productions of these two cultural periods but also allows, unlike the neoclassical unities, a non-anachronistic philosophical vocabulary of whole and parts or of the general and particular in the criticism of poetry, which involution provides a “rule” more consonant with the laws of the imagination rather than with the rhetorical and absolutist dicta that were thither available in the literary canon.

Illness and Fall in Albert Camus

This article focuses on the theme of illness in Albert Camus. Special emphasis is placed on his last published novel, La Chute. The issue of disease is usually focused in relation to death and finitude both in literature and philosophy. This article focuses on the relation between the existential experience of illness and the decay of the plenitude of life. The case of Albert Camus is especially significant for his chronical illness and because disease has a prominent place in his literary works. Here La Chute is chosen because it offers a great richness of interpretative levels unparalleled in other camusian works. Two different reading levels are proposed. The distinction and the analysis of these two levels will allow for more nuanced view of the relationship of the author to his work and of the controversy about the social role of the intellectual. The conclusion of this article differs both from the critics who only consider the novel in relation to the polemic with Jean-Paul Sartre, and those who interpret it as a disguised confession.

Game Learning Analytics: Learning Analytics for Serious Games

Video games have become one of the largest entertainment industries, and their power to capture the attention of players worldwide soon prompted the idea of using games to improve education. However, these educational games, commonly referred to as serious games, face different challenges when brought into the classroom, ranging from pragmatic issues (e.g. a high development cost) to deeper educational issues, including a lack of understanding of how the students interact with the games and how the learning process actually occurs. This chapter explores the potential of data-driven approaches to improve the practical applicability of serious games. Existing work done by the entertainment and learning industries helps to build a conceptual model of the tasks required to analyze player interactions in serious games (gaming learning analytics or GLA). The chapter also describes the main ongoing initiatives to create reference GLA infrastructures and their connection to new emerging specifications from the educational technology field. Finally, it explores how this data-driven GLA will help in the development of a new generation of more effective educational games and new business models that will support their expansion. This results in additional ethical implications, which are discussed at the end of the chapter.

Episodic Future Thinking in 4-Year-Olds, Poster Symposium: The who, what, where and when of episodic foresight development

The ability to project oneself into the future to pre-experience an event is referred to as episodic future thinking (Atance & O’Neill, 2001). Only a relatively small number of studies have attempted to measure this ability in pre-school aged children (Atance & Meltzoff, 2005; Busby & Suddendorf, 2005ab, 2010; Russell, Alexis, & Clayton, 2010).Perhaps the most successful method is that used by Russell et al (2010). In this task, 3- to 5-year-olds played a game of blow football on one end of a table. After this children were asked to select tools that would enable them to play the same game tomorrow from the opposite, unreachable, side of the table. Results indicated that only 5-year-olds were capable of selecting the right objects for future use more often than would be expected by chance. Above-chance performance was observed in this older group even though most children failed the task because there was a low probability of selecting the correct 2 objects from a choice of 6 by chance.This study aimed to identify the age at which children begin to consistently pass this type of task. Three different tasks were designed in which children played a game on one side of a table, and then were asked to choose a tool to play a similar game on the other side of the table the next day. For example, children used a toy fishing rod to catch magnetic fish on one side of the table; playing the same game from the other side of the table required a different type of fishing rod. At test, children chose between just 2 objects: the tool they had already used, which would not work on the other side, and a different tool that they had not used before but which was suitable for the other side of the table. Experiment 1: Forty-eight 4-year-olds (M = 53.6 months, SD = 2.9) took part. These children were assigned to one of two conditions: a control condition (present-self) where the key test questions were asked in the present tense and an experimental condition (future-self) where the questions were in the future tense. Surprisingly, the results showed that both groups of 4-year-olds selected the correct tool at above chance levels (Table 1 shows the mean number of correct answers out of three). However, the children could see the apparatus when they answered the test questions and so perhaps answered them correctly without imagining the future. Experiment 2: Twenty-four 4-year-olds (M = 53.7, SD = 3.1) participated. Pre-schoolers in this study experienced one condition: future-self looking-away. In this condition children were asked to turn their backs to the games when answering the test questions, which were in the future tense. Children again performed above chance levels on all three games.Contrary to the findings of Russell et al. (2010), our results suggest that episodic future thinking skills could be present in 4-year-olds, assuming that this is what is measured by the tasks. Table 1.

Das Bildzitat Eine Untersuchung von Paul Klees Die Revolution des Viaduktes in drei Texten der deutschprachigen Prosa

Ziel dieser Arbeit ist die Untersuchung des Bildzitates und seiner Form. Ausgangspunkt ist ein Kunstwerk, Paul Klees Revolution der Viadukte, und dessen Versprachlichung, dem sognannten Bildzitat, in drei Texten der deutschen Prosa. Als literaturwissenschaftliche Methode wurde ein intermedialer Ansatz nach Rajewsky, sowie von Berndt, Tonger-Erk gewählt. Eine Auswahl des Kunstwerkes und der Texte, die das Kunstwerk zitieren, wurde basierend auf dem Material der Datenbank über literarische Bildzitate in Wien getroffen. Die Analyse der Bildzitate in SAID: Das Rot lächelt, das Blau schweigt. Geschichten über Bilder, Uwe Timm: Der Freund und der Fremde und Gertrud Leutenegger: Vorabend erfolgt nach folgender Fragestellung: 1. Welches sind die grundlegenden Charakteristika des Bildes, die in den literarischen Bildzitaten hervorgehoben werden? 2. Mit welchen sprachlichen Mitteln wird dies hervorgehoben? 3. Welche Rolle spielt der Titel des Gemäldes? Wie der Resultatteil zeigt werden von den Autoren Stilmittel ähnlich die des Gemäldes (Kontrast, Repetition) verwendet. Der Titel des Gemäldes und die Bildzitate werden im Text als verstärkendes Element verwendet. The pictorial quote An analysis of Paul Klees Revolution of the viaduct in three German prose texts. This essay explores the quotation of images in literature. Starting point is Paul Klee's painting The revolution of the viaduct and its verbal expression, which is known as 'image quotation', in three German prose texts. The textual analysis of these works - SAID's Das Rot lächelt,das Blau schweigt. Geschichten über Bilder, Uwe Timm's Der Freund und der Fremde and Gertrud Leutenegger's Vorabend - is based on theories of intermediality. This essay shows that the authors employ stylistic devices similar to those in the painting, such as contrast and repetition, and use them as intermedial references.

Affect-Based Effects of Simulation Games on Learning

Empirical evidence has demonstrated the benefits of using simulation games in enhancing learning especially in terms of cognitive gains. This is to be expected as the dynamism and non-linearity of simulation games are more cognitively demanding. However, the other effects of simulation games, specifically in terms of learners’ emotions, have not been given much attention and are under-investigated. This study aims to demonstrate that simulation games stimulate positive emotions from learners that help to enhance learning. The study finds that the affect-based constructs of interest, engagement and appreciation are positively correlated to learning. A stepwise multiple regression analysis shows that a model involving interest and engagement are significantly associated with learning. The emotions of learners should be considered in the development of curriculum, and the delivery of learning and teaching as positive emotions enhances learning.

Unreal PowerPoint™: Immersing PowerPoint Presentations in a Virtual Computer Game Engine World

At a recent conference on games in education, we made a radical decision to transform our standard presentation of PowerPoint slides and computer game demonstrations into a unified whole, inserting the PowerPoint presentation to the computer game. This opened up various questions relating to learning and teaching theories, which were debated by the conference delegates. In this paper, we reflect on these discussions, we present our initial experiment, and relate this to various theories of learning and teaching. In particular, we consider the applicability of “concept maps” to inform the construction of educational materials, especially their topological, geometrical and pedagogical significance. We supplement this “spatial” dimension with a theory of the dynamic, temporal dimension, grounded in a context of learning processes, such as Kolb’s learning cycle. Finally, we address the multi-player aspects of computer games, and relate this to the theories of social and collaborative learning. This paper attempts to explore various theoretical bases, and so support the development of a new learning and teaching virtual reality approach.

Emergency emicolectomy for intestinal primary Aspergillosis in acute myeloid leukemia

ntestinal aspergillosis is an infection with a very high death rate especially in leukemic patients. Here we describe a case of a 46 years old woman with acute myeloid leukemia (LAM M5) who developed intestinal primary aspergillosis. This patient was diagnosed with LAM M5 through bone marrow aspiration and bone biopsy in March 2004. Symptoms of the disease were slight persistent fever, weight loss, asthenia, anemia, thrombocytopenia,and leukocytosis with high number of blasts in peripheral blood. After induction chemotherapy with ICE (Ifosfamide, Carboplatin, Etoposide), she developed neutropenia and high fever without apparent infective foci. She was treated with empiric antibiotic therapy, nevertheless she developed an intense diarrhea and ileo-cecal distention. Diagnostic exams didn’t show signs of a focal lesion. Despite the change in antibiotic treatment and the transfusions of granulocytes and blood cells, the patient developed extremely critical conditions with persistence of neutropenia and abdominal distention. A surgical treatment was decided at the time. We treated the patient with a two steps surgical procedure. The first step was a right abdominal ileostomy followed by improvement of general conditions and then the second step a right colectomy. The histological morphology confirmed necrotizing colitis with Aspergillus ife. At that time , treatment with voriconazole was started. The general conditions of the patient improved rapidly and we were able to treat the patient with other medical anti-leukemic therapies. The patient is now cured and in healthy state. We obtained a good clinical result as only in other few cases described in literature.

Chemistry of potassium halides and their role in corrosion in biomass and waste firing

Compared to the use of traditional fossil fuels (coal, oil, natural gas), combustion of biomass and waste fuels has several environmental and economic advantages for heat and power generation. However, biomass and waste fuels might contain halogens (Cl, Br, F), alkali metals (Na, K) and heavy metals (Zn, Pb), which may cause harmful emissions and corrosion problems. Hightemperature corrosion occurs typically on furnace waterwalls and superheaters. The corrosion of the boiler tube materials limits the increase of thermal efficiency of steam boilers and leads to costly shutdowns and repairs. In recent years, some concerns have been raised about halogen (Cl, Br, and F)-related hightemperature corrosion in biomass- and waste-fired boilers. Chlorine-related high-temperature corrosion has been studied extensively. The presence of alkali chlorides in the deposits is believed to play a major role in the corrosion observed in biomass and waste fired boilers. However, there is much less information found in literature on the corrosion effect of bromine and fluorine. According to the literature, bromine is only assumed to play a role similar to chlorine; the role of fluorine is even less understood. In this work, a series of bubbling fluidized bed (BFB) bench-scale tests were carried out to characterize the formation and sulfation behaviors of KCl and KBr in BFB combustion conditions. Furthermore, a series of laboratory tests were carried out to investigate the hightemperature corrosion behaviors of three different superheater steels (10CrMo9-10, AISI 347 and Sanicro 28) exposed to potassium halides in ambient air and wet air (containing 30% H2O). The influence of H2O and O2 on the high-temperature corrosion of steels both with and without a salt (KCl) in three gas atmospheres (2% H2O-30% O2-N2, 2% H2O-2% O2-N2 and 30% H2O-2% O2-N2) was also studied. From the bench-scale BFB combustion tests, it was found that HBr has a clearly higher affinity for the available K forming KBr than HCl forming KCl. The tests also indicated that KCl has a higher tendency for sulfation than KBr. From the laboratory corrosion tests in ambient air (also called “dry air” in Paper III and Paper IV), it was found that at relatively low temperatures (≤ 550 °C) the corrosivity of KBr and KF are similar to KCl. At 600 °C, KF showed much stronger corrosivity than KBr and KCl, especially for 10CrMo9-10 and AISI 347. When exposed to KBr or KF, 10CrMo9-10 was durable at least up to 450 °C, while AISI 347 and Sanicro 28 were durable at least up to 550 °C. From the laboratory corrosion tests in wet air (30% H2O), no obvious effect of water vapor was detected at 450 °C. At 550 °C, the influence of water vapor became significant in some cases, but the trend was not consistent. At 550 °C, after exposure with KBr, 10CrMo9-10 suffered from extreme corrosion; after exposure with KF and KCl, the corrosion was less severe, but still high. At 550 °C, local deep pitting corrosion occurred on AISI 347 and Sanicro 28 after exposure with KF. Some formation of K2CrO4 was observed in the oxide layer. At 550 °C, AISI 347 and Sanicro 28 suffered from low corrosion (oxide layer thickness of < 10 μm) after exposure with KBr and KCl. No formation of K2CrO4 was observed. Internal oxidation occurred in the cases of AISI 347 with KBr and KCl. From the laboratory corrosion tests in three different gas atmospheres (2% H2O-30% O2-N2, 2% H2O-2% O2-N2 and 30% H2O-2% O2-N2), it was found that in tests with no salt, no corrosion occurred on AISI 347 and Sanicro 28 up to 600 °C in both the “O2-rich” (2% H2O-30% O2-N2) and “H2O-rich” (30% H2O-2% O2-N2) gas atmospheres; only 10CrMo9-10 showed increased corrosion with increasing temperature. For 10CrMo9-10 in the “O2-rich” atmosphere, the presence of KCl significantly increased the corrosion compared to the “no salt” cases. For 10CrMo9-10 in the “H2O-rich” atmosphere, the presence or absence of KCl did not show any big influence on corrosion. The formation of K2CrO4 was observed only in the case with the “O2-rich” atmosphere. Considering both the results from the BFB tests and the laboratory corrosion tests, if fuels containing Br were to be combusted, the corrosion damage of superheaters would be expected to be higher than if the fuels contain only Cl. Information generated from these studies can be used to help the boiler manufacturers in selecting materials for the most demanding combustion systems.
