L'économie participaliste, ou écopar, est un système économique proposé comme une alternative au capitalisme et au socialisme « réel ». La vie économique y est régie par des conseils de travailleurs et de travailleuses ainsi que des conseils de consommation autogérés et fédérés par l'entremise d'un processus de planification participative. Quelques propositions institutionnelles pour les fonctions non économiques de la société ont aussi été formulées pour complémenter le projet d'écopar, mais ces propositions sont au mieux encore incomplètes, quoiqu'il existe un squelette de plus en plus précis de système politique participaliste. Les formes de l'écopar, qui entendent actualiser les valeurs d'équité, d'autogestion, de solidarité et de diversité sans perte d'efficience économique, s'inspirent grandement de l'anarchisme social et du conseillisme. En analysant l'écopar sur la base de la pensée anarchiste, complémentée par le féminisme matérialiste, nous en arrivons à la conclusion qu'elle constitue une forme de socialisme collectiviste et libertaire apte à produire une société sans classes sociales et protégée contre la dérive autoritaire du socialisme « réel ». ______________________________________________________________________________ MOTS-CLÉS DE L’AUTEUR : écopar, économie participaliste, participalisme, Michael Albert, Robin Hahnel, anarchisme

Denna uppsats rör den moral som presenteras för oss i amerikanska äventyrsfilmer. Tre filmer, King Arthur, Robin Hood och Gladiator, presenteras och analyseras. Hjältens handlingar är i fokus men även antagonisten och andra bikaraktärers handlingar är av vikt. Detta ställs mot den traditionella pliktetiken då vi får se om hjältens handlingar är förenliga eller strider mot den. En diskussion följer också kring filmernas upplägg och vad lockelsen med denna typ av film egentligen är.

Real-time system refers to the computing, communication, and information system with deadline requirements. To meet these deadline requirements, most systems use a mechanism known as the schedulability test which determines whether each of the admitted tasks can meet its deadline. A new task will not be admitted unless it passes the schedulability test. Schedulability tests can be either direct or indirect. The utilization based schedulability test is the most common schedulability test approach, in which a task can be admitted only if the total system utilization is lower than a pre-derived bound. While the utilization bound based schedulability test is simple and effective, it is often difficult to derive the bound. For its analytical complexity, utilization bound results are usually obtained on a case-by-case basis. In this dissertation, we develop a general framework that allows effective derivation of schedulability bounds for different workload patterns and schedulers. We introduce an analytical model that is capable of describing a wide range of tasks' and schedulers'€™ behaviors. We propose a new definition of utilization, called workload rate. While similar to utilization, workload rate enables flexible representation of different scheduling and workload scenarios and leads to uniform proof of schedulability bounds. We introduce two types of workload constraint functions, s-shaped and r-shaped, for flexible and accurate characterization of the task workloads. We derive parameterized schedulability bounds for arbitrary static priority schedulers, weighted round robin schedulers, and timed token ring schedulers. Existing utilization bounds for these schedulers are obtained from the closed-form formula by direct assignment of proper parameters. Some of these results are applied to a cluster computing environment. The results developed in this dissertation will help future schedulability bound analysis by supplying a unified modeling framework and will ease the implementation practical real-time systems by providing a set of ready to use bound results.

After King William created the New Forest in the twelfth century, the English monarchy sought to define the vert, both legally and ideologically, as a site in which the king’s rights were vigorously enforced. In the romance literature of England, the forest was treated as an exclusive chivalric testing ground, as the site of the aristocracy’s self-validation. The folk reaction against the privatization of this common space and its resources finds a strong literary articulation in the first Robin Hood ballads centuries later. The outlaw reclaims the forest by inhabiting it, appropriating the symbols of its governance, and establishing within it a court that is both legal and social, decked out in the trappings and traditions of romance chivalry and the forest administration. This thesis examines the ideological impulses behind Robin’s occupation of the forest, discussing their relationship to the legal and literary history of the English forest.

Pigeon Valley Park, on Durban's Berea Ridge, is an approximately 10-ha remnant of coastal forest, which is totally surrounded by suburban housing and roads. As such it is ideal as a study area for investigating the applicability of the MacArthur-Wilson Theory of Island Biogeography (1963,1967) and Diamond's (1975) geometric reserve-design principles to fragmented Coastal Forests in Durban. This study began in January 1989 and the results are reported as at October 1992. Field notes from as far back as 1981 were used to augment the findings of the current work. Research focused on the forest-dwelling, Natal Robin Cossypha natalensis, and territory mapping showed that the reserve supports up to 53 individuals during the breeding season. An annotated checklist and its comparison to historical and regional checklists revealed where localised extinctions may have occurred, and thus identifies a set of coastal forest species which are susceptible to habitat fragmentation. Work on two potential dispersal corridors for bird movement into and out of the valley showed that the reserve is not yet fully isolated to most species which are currently present. On the other hand, there are some forest species which have isolated populations at Pigeon Valley Park, as well as others which do not seem able to establish and maintain viable populations. A set of 'indicator', forest bird species which are susceptible to habitat fragmentation, is defined. Practical management suggestions with the aim of increasing the long-term viability of the area as an avifaunal preserve, are presented. / Thesis (M.Sc.)-University of Natal, Durban,1992.

Ce mémoire propose des lectures croisées de la mémoire urbaine dans Dora Bruder de Patrick Modiano et La Québécoite de Régine Robin. Les deux récits mettent en scène des narrateurs héritiers de la mémoire de la Shoah qui déambulent dans les villes de Paris et Montréal. La ville est espace d’intelligibilité dont les signes sont porteurs de sens à activer par l’observateur. À l’aide de la sémiotique de la ville (Benjamin) et des pratiques de la ville (De Certeau) et en tenant compte de la position particulière des narrateurs autour des enjeux du témoignage et de l’écriture, ce mémoire cherche à étudier comment la ville participe au déploiement d’une mémoire juive en même temps qu’elle contribue à son inévitable perte. La Deuxième Guerre mondiale a eu lieu en partie à Paris, qui en porte les traces dans une forte densité mémorielle, tandis que Montréal, ville diasporique où les événements ne se sont pas déroulés, accueille les mémoires écorchées qui se fixent d’une autre manière dans l’espace urbain. Dans les deux récits, l’espace urbain est nécessaire à la mise en texte de la rupture et de la perte, qui se dévoilent à la fois au niveau thématique (destruction urbaine, échecs répétés, perte identitaire) et formel (remise en question du récit, hybridité générique.) / This thesis offers crossed readings of urban memory in Dora Bruder from Patrick Modiano and La Québécoite from Régine Robin. Both stories depict narrators heirs of the Holocaust memory who roam the cities of Paris and Montreal. The city is a space of intelligibility whose signs are meaningful to the observer. Using the semiotics of the city (Benjamin), the practices of the city (De Certeau) and taking into account the specific position of both narrators on the issues of testimony and writing, this study seeks to explore how the city spreads the Jewish memory while at the same time contributing to its inevitable loss. The Second World War took partly place in Paris, which bears the traces in a high density of memory, while Montreal, a city where Holocaust events did not unfold, is hosting memories otherwise within its urban space. In both stories, the city is necessary to the writing of the breakdown and loss, which reveal themselves both in the background (urban destruction, repeated failures, loss of identity) and form (question of the story, generic hybridity.)

Predation is the highest cause of mortality for birds and can place intense selection pressures on their behavioural traits. A number of studies have shown that some animals have innate predator recognition, while others which are predator-naïve have been unable to adapt to the introduction of exotic predators. For my thesis, I firstly studied how eight species of introduced and native birds respond to model predators at their nests. This enabled me to determine whether the native birds have been able to adapt to introduced mammalian predators and have developed recognition of them being a threat. In most species, the reaction to the stoat (Mustela erminea) (an introduced predator) was similar to that of a model morepork (Ninox novaeseelandiae) (a native predator). This suggests these species can successfully recognise introduced mammals as a risk. It also allowed me to test whether recently introduced birds have any innate recognition of snakes, which are a significant nest predator in their native ranges but do not exist in New Zealand. I found that introduced birds did not appear to have any recognition of snakes as being a threat. These losses and gains of recognition may have been caused by evolutionary changes or they may be influenced by learning and experience. Secondly, I examined how South Island robins (Petroica australis) on a predator-free island responded to predator models and compared this to the responses of robins on the mainland (where they co-occur with mammalian predators). The island birds were assumed to show the ancestral reactions to mammalian predators, while any differences in response shown by the mainland robins would indicate they had acquired these behaviours in response to increased predation risk. I found that the island robins did not appear to recognise or react to a taxidermic mount of a stoat while mainland robins did respond to the stoat, confirming that at least some native birds can develop recognition of novel predators. Finally, I compared the personalities of South Island robins on a predator-free island and on the mainland (where mammalian predators are present). I tested where individuals placed on the ‘bold-shy’ continuum by observing their willingness and speed to approach a risky situation in order to collect food. Studies have shown that average personality between populations can differ where predation risk differs. I found that the island robins were on average bolder than mainland robins. They came nearer to the observer and were faster to approach and remove a food item, while mainland robins were less likely to approach, and those that did approach took a longer time. It is likely that these differences were due to selection pressures by mammalian predators favouring shy individuals on the mainland while other pressures such as interspecific competition favours bold individuals on the island. Personality has been shown to be genetic and heritable, however, learning and experience cannot be ruled out and may also play a part in influencing how personality is expressed. Together, my results support the importance of historical and ontogenetic factors in influencing how predator recognition and personality traits are expressed.

The purpose of this comparison and analysis was to examine the tenets of expressionism and existentialism as found in the aesthetic theories of Robin G. Collingwood and Eugene F. Kaelin, respectively. It was felt that both aesthetics proper, as a philosophic concern, and educational practices in art could benefit by the tenets of these two theories. In addition, many of the concepts explored were found to be mutually complementary not only in a logical sense but also in terms of clarifying the process of creation of works of art as well as contributing a pellucid view of response to art works.
