This book analyses the aesthetic and utopian dimensions of various activist social movements in Western Europe since 1989. Through a series of case studies, it demonstrates how dreams of a better society have manifested themselves in contexts of political confrontation, and how artistic forms have provided a language to express the collective desire for social change.
The study begins with the 1993 occupation of Claremont Road in east London, an attempt to prevent the demolition of homes to make room for a new motorway. In a squatted row of houses, all available space was transformed and filled with elements that were both aesthetic and defensive – so when the authorities arrived to evict the protestors, sculptures were turned into barricades. At the end of the decade, this kind of performative celebration merged with the practices of the antiglobalisation movement, where activists staged spectacular parallel events alongside the global elite’s international meetings. As this book shows, social movements try to erase the distance that separates reality and political desire, turning ordinary people into creators of utopias. Squatted houses, carnivalesque street parties, counter-summits, and camps in central squares, all create a physical place of these utopian visions

Regression testing is a common and necessary task carried out by software practitioners to validate the quality of evolving software systems. Unfortunately, regression testing is often an expensive, time-consuming process, particularly when applied to large software systems. Consequently, practitioners may wish to prioritize the test cases in their regression test suites to execute more important test cases earlier in the regression testing process. One common goal of this test case prioritization is to increase a test suite's rate of fault detection, a measure of how quickly faults are detected by a test suite. Recent research has begun to incorporate the practical issues of varying test costs, test criticalities and fault severities into test case prioritization techniques and metrics measuring the rate of fault detection of these techniques. However, more empirical data is needed to sufficiently examine both the metrics and techniques developed by this research. To address this need, we conducted a case study to further examine the effectiveness of various prioritization techniques that incorporate varying test costs and criticalities. Software practitioners can use the results of this study to help enhance the effectiveness of their regression testing procedures and, in doing so, improve the quality of their software.

A comparison of Napoleon: Total War (The Creative Assembly 2010) and indie title Scourge of War: Gettysburg (Norb Software Development 2010) illustrates the role of different conceptions of realism in the development of games with a tactical battlefield component. The incoherence of Napoleon’s tactical realism proved no barrier to popular and critical success and—when compared with the largely unknown Scourge of War—such popularity affords an insight into the preference on the part of players and critics alike for games that feature a sophisticated re-packaging of versions of reality based on cinematic convention.

Objetivo: describir el comportamiento demográfico y clínico de los pacientes traumatizados de una institución de cuarto nivel
de complejidad que ingresaron entre el 2005 y el 2008. Metodología: estudio descriptivo retrospectivo basado en información
de pacientes que ingresaron a urgencias y hospitalización. Se estimaron frecuencias y porcentajes para las variables
demográficas y algunas clínicas. Finalmente, se realizó un muestreo aleatorio simple para estimar la puntuación de gravedad de las lesiones (trauma and injury severity score-TRISS). Resultados: en este período ingresaron 165736 pacientes, de ellos, 57382 correspondieron a ingresos por trauma (35% del total). El sexo masculino y el grupo de edad de 20-29 años fueron los más afectados. La causa de ingreso predominante fue la de accidentes de tránsito, seguida por otros tipos de accidentes (caídas, quemaduras, ahogamientos). Fueron hospitalizados 6721 pacientes, de los cuales fallecieron 278, con tasa de mortalidad global de 4,1. La parte del cuerpo más afectada en estos pacientes fueron las extremidades (42%) y los traumas en cabeza y cuello (19%). Para estimar la TRISS, se analizaron en total 347 pacientes. El índice de severidad del trauma (ISS)
calculado fue mayor de 49 en 3,17% de los pacientes analizados. La escala revisada de trauma (RTS) promedio fue de 7507. Las cifras de presión arterial sistólica y frecuencia respiratoria presentaron una media de 121,948 mmHg y 18,659 min respectivamente, y en la escala de coma de Glasgow, 30 pacientes obtuvieron un puntaje menor o igual a 8. El total de muertes esperadas correspondió a 17 pacientes y el total de muertes observadas a 19. Finalmente, la TRISS calculada fue de 1,097. Conclusión: El ISS es un buen indicador de la severidad de los pacientes traumatizados y mediante la utilización de la RTS y de la edad, fue factible estimar la TRISS; la mortalidad observada resultó levemente mayor a lo esperado, lo cual indica que la calidad en la atención prestada a los pacientes traumatizados en esta institución de cuarto nivel puede mantenerse o mejorarse, ya que se presentaron aproximadamente dos muertes más de las esperadas.

The medium access control (MAC) protocol for Mobile Adhoc Network (MANET) need to be distributed, QoS assured, fair to all flows and should work in a multihop environment. Although there are numerous MAC protocol proposed for MANET, very few of them possesses all the above properties. This paper, which proposes a MAC protocol for adhoc network have all the above mentioned properties. The protocol supports quality of service and exhibit flow based fairness over multihop adhoc network. In accordance with the protocol, high prioritized traffic flows are allowed to access the channel earlier than the low prioritized traffic flows. If multiple numbers of flows of the same priority level are active in the network then the fairness factor comes into account .The less served flow, and then gets the priority over the highly served flow in accessing the channel. The performance of the protocol is evaluated analytically. The result shows that the high prioritized traffic flow experience less delay and have more throughputs as compared to others.

Present study evaluates the changes and developmental trajectories of the attentional serial visual search and pre-attentional parallel search (pop-out) in situations in which a fast response is required. The hypothesis of present study are 1) that pre-attentional selection mechanisms develop before than serial attentional processes; 2) in the most difficult tasks, children prefer to adopt a non-responding strategy to an impulsive response patters; and 3) in speeded difficult discrimination tasks young children arrives to the criteria of correct performance in a broad temporal window. The results showed an inverse relationship between the age and the RTs and the different type of errors. For the present set of stimuli which produces an overcrowded scene and required a fast response, the behavioural trend of normal children is to the non-response pattern rather than to impulsive incorrect responses pattern. It can be suggested that young normal children present a broad temporal windo...

Communication protocols and techniques are often evaluated using simulation techniques. However, the use of formal modeling and analysis techniques for verification and evaluation in particular for Wireless Sensor Networks (WSN) becomes a necessity. In this paper we present a formal analysis of the backoff procedure integrated in the medium access control protocol named ECo-MAC designed for WSN. We describe this backoff procedure in terms of discrete time Markov chains (DTMCs) and evaluated using the well known probabilistic model checker PRISM. After checking the different invariants of the proposed model, we study the effect of contention window length (in number of time contention unit) on the acceptable number of simultaneous senders in a neighborhood of a given receiver. The obtained quantitative results confirm those provided by the simulation using OPNET tool and justify the validity of the adopted value for the time contention unit TCU.
