This dissertation identifies the diluting effects that network society has had on the avant-garde subcultures, by first building a framework through which to understand the social structure and spatial production of the historical avant-garde, and then comparing this with contemporary avant-garde movements. The avant-garde is a cultural tradition that originated in modern 18th century Europe and North America, that critically responds to hegemonic power structures and mainstream cultural assumptions. I use the term “avant-garde subcultures” because my research focuses on the entire social group of the avant-garde. Most scholarship on the avant-garde has overlooked the importance that social relations, in particular supportive actors, and collaborative spaces have served in the creativity of the avant-garde. During the past twenty years, as society has shifted into a dependence on networked interactive technologies, the boundaries which protect these avant-garde spaces and social relations were diluted. As a result, avant-garde subcultures have entered a phase of recursively repeating themselves and culturally stagnating. I begin by reviewing the historical avant-garde and subcultures, building an overarching theory that explains that avant-garde is a type of subculture. Using past scholarship that maps the conceptual lineage from early bohemians to 1970s punk rock, I synthesize a set of traits which all avant-garde subcultures exhibit, and which can be used to build their genealogy. I then extend this genealogy to contemporary art practitioners, to prove that the avant-garde tradition continues to this day. Next, I develop a philosophical understanding of the importance of space for hegemonic power structures, based largely on the work of Henri Lefebvre. I explain how avant-garde subcultures produce spaces of representation in the cafes, bars and night clubs they inhabit, which challenge hegemony by being different from normal values and aesthetics. I reference first-hand accounts of these spaces of representation, to show how they enable the collaboration and creative thinking that is most often associated with the avant-garde. The avant-garde protect these spaces through a set of cultural boundaries: fashion, slang, esoteric knowledge, accumulation, and physical space. Manuel Castell's concept of network society depicts how hegemonic power structures have become pervasive, and thus can overcome the boundaries of avant-garde subcultures. As a result, avant-garde subcultures have increasingly become retrogressive and fluid. Some avant-garde practitioners, such as tactical media, have evolved methods for addressing these problems. While these are effective in continuing the avant-garde tradition of introducing difference, there are no adequate methods for producing new spaces of representation. I examine Eyebeam, an arts and technology center, which has since 1997 provided a space for many contemporary practitioners. While unique in its circumstances, Eyebeam has adopted several processes which have enabled it to overcome the diluting effects of network society, thereby providing a potential model for building future spaces of representation.

Every commander in his practice makes various solutions. Every situation, which is related to making a decision has a feature – it is always possible to find a few ways to solve a problem and, in order to accompilish the military assignment, the most optimal ant the best way must be chosen. It is practically impossible to make an optimal solution in the battle in up-to-date conditions if one hadn‘t learned to foresee the outcome if the one or another solution would have been chosen. The prevision of possible rezults is an essential part of any expedient action, as well as military. There are many complicated situations in the battle, when it is impossible to lead and win without a prognostication and prevision. The prognostication is a deciding factor while leading the detachments. The information, obtained while forecasting is the scientific base of any decision. The prognostication can be empirical and mathematical. The empirical prognostication is based on practical experience and intuition, and it was used for a long time while forecasting possible actions. But nowadays the munition, technique and tactics are improving so fast and it‘s not enough to use only the empirical prognostication to win the battle. The scientific methods are used in prognostication in an up-to-date war. Calculation, obtained with reference to scientific methods can confirm the information, obtained while using intuition and practical experience. So, the appropriate corrections can be done...

The power requirement for the soldier's equipment is largely supplied by batteries. Situational awareness is critical for a soldier to perform his tasks. Therefore the radio used by the soldier is a key element in situational awareness and also consumes the most power. The South African National Defence Force (SANDF) uses the A43 tactical radio specifically designed for them. The radios are regarded as old technology but will be in use for about another five years. The radios still use non-rechargeable alkaline batteries which do not last very long and are not cost effective. The purpose of this study is to research the new generation secondary batteries as a possible replacement for the alkaline battery packs. The new generation batteries investigated in this study are the latest rechargeable batteries, also called secondary batteries. They include nickel cadmium, nickel metal hydride, lithium ion, rechargeable alkaline manganese and zinc air. The main features of rechargeable cells are covered and the cell characteristics are defined to allow the technology to be matched to the user requirement. Li-ion technology was found to be the best choice. This research also showed that international trends in battery usage are towards Li-ion. A new Li-ion battery was designed based on commercial cells. Tests showed that commercial Li-ion cells can be used in the radio and that they outperform the current battery by far. The study also examined the design of a New Generation Battery System consisting of an intelligent battery, a charger which uses a Systems Management Bus and a battery 'state of health" analyser to assist the user to maintain the batteries. Tests were done to demonstrate that the battery can withstand typical military environmental conditions. Expected military missions for a battery system were defined and used to compare the cost between the existing batteries and the new batteries system. Important usage factors which will influence the client when using a New Generation Battery System were addressed. To summarise, this study showed that by using a New Generation Battery System, the SANDF could relieve the operational cost of the A43 radio while saving on weight and enabling the soldier to carry out longer missions. / Thesis (M.Ing.

La gestion de chaîne d’approvisionnement est un élément essentiel à la performance des entreprises et fait l’objet d’une attention particulière depuis plusieurs décennies. Dans le domaine des télécommunications, cette gestion inclût généralement des activités de réparation et prend alors place sur une chaîne d’approvisionnement en boucle fermée. Dans ce contexte, la gestion de la chaîne d’approvisionnement vise à la planification optimale des mouvements de pièces saines et défaillantes basée sur une prévision des défaillances futures et fait face à différents objectifs conflictuels (rupture de stock, stockage, réparation,transfert). Le travail présenté dans cette thèse s’intéresse à ce problème d’optimisation et s’appuie sur un cas réel. Spécifiquement nous proposons un système d’aide à la planification tactique. Ce système est centré sur une modélisation générique du problème d’optimisation applicable à une grande variété de chaînes d’approvisionnement. Nous présentons particulièrement une approche exacte et une méta-heuristique pour résoudre ce problème et évaluons ces approches sur une variété d’instances de différentes tailles avec plusieurs niveaux et distributions du stock initial dans la chaîne d’approvisionnement. Nous étudions également la possibilité de mener des politiques de gestion particulières (e.g., juste-à-temps, réparations minimales) en pondérant les différents objectifs étudiés. Nous nous intéressons également à l’application de plans successifs produits par le système et, particulièrement, nous étudions la capacité du système à faire face aux incertitudes pouvant apparaître dans les prévisions. / Supply chains are ubiquitous across industries and a considerable effort has been invested in supply chain management techniques over the last decades. In Telecommunications service industries, it often involves repair operations and consequently takes place in a closed-loop supply chain. In this context, supply chain management is concerned with optimally planning movements of faulty parts and spare parts based on a demand forecast and in the face of conflicting objectifs (stock out, storage, repair, transfer). This thesis describes this optimisation problem and based on a case study. Specifically, we consider a tactical planning decision support system. This system depends on a generic modeling of the problem that can be applied on a wide range of supply chains. We present an exact method and a metaheuristic to solve this problem and evaluate our approaches against a variety of instances of different sizes. We also study the ability to emulate specific management policies (e.g., just-in-time replenishment, minimal repair) by weighting the objectives. Finally, we investigate how to apply successive plans generated by the system and study the capability to face forecast uncertainties.

Introduction Clinical decision-making, situation awareness, task management, and teamwork are key non-technical skills (NTS) required by junior doctors. However, research has demonstrated that new doctors have difficulty demonstrating effective NTS behaviours. Tactical decision games (TDGs) are low-fidelity classroom-based activities designed to develop proficiency in NTS. They have been used in other safety-critical industries to develop NTS but their use in undergraduate medical education has been very limited. This aim of this thesis was to explore the potential role of TDGs as a novel method of developing final year medical students’ NTS. Methods Throughout this thesis a qualitative approach was taken, underpinned by constructivist epistemology. In the first instance the feasibility and acceptability of using generic (non-medical) TDGs with groups of final year medical students was explored. Thereafter, the use of non-medical TDGs and acute care simulation scenarios to develop NTS was investigated. Acute medical TDGs were developed with support and guidance from an expert panel. The potential role of medical TDGs to develop final year medical students’ NTS was then explored. Medical TDGs were then implemented into the core undergraduate curriculum in the clinical assistantship programme. Results In the feasibility study six key themes emerged from the data: ‘‘the value of non-medical games’’; ‘‘giving and receiving feedback’’; ‘‘observing and reflecting’’; ‘‘recognizing and understanding NTS’’; ‘‘dealing with uncertainty and ambiguity’’, and ‘‘introducing TDGs into the curriculum’’. Exploring the use of non-medical TDGs and acute care simulation to develop NTS, five key themes emerged from the data: “situation awareness and fixation”; “expectations influencing behaviour”; “being uncomfortable with uncertainty”; “transmitting and receiving information” and “working with peers and seniors”. Using acute medical TDGs to develop NTS, five key themes emerged from the data: “understanding capabilities and responsibilities of team members”; “prioritising in a busy clinical environment”; “developing a workable solution”; “relating medical TDGs to clinical experience” and “introducing medical TDGs into the undergraduate curriculum”. A team of facilitators were trained and medical TDGs delivered to the full final year cohort in the clinical assistantship programme. Discussion and conclusions This thesis has found that generic and acute medical TDGs represent an exciting potential method of teaching medical students NTS. TDGs appear to be versatile activities that can be adapted to meet the needs of participants in different contexts. As such, the full potential of TDGs in the undergraduate curriculum and beyond remains to be explored.

Para isso, optamos por utilizar entrevistas com professores de Matemática que possuem posições de comando em instituições de ensino superior na cidade de Maringá (PR). A História Oral, utilizada como método dessa nossa investigação, possibilitou a utilização da memória mais como meio para a análise das ações por ela governadas e menos pelo conhecimento que, pela memória, foi possível registrar. A interconexão entre as opções metodológica e teórica presentes neste estudo possibilitaram a articulação de três elementos que julgamos fundamentais para compreender a Educação como instrumento de distribuição de poderes e saberes: o controle da natureza, o controle social e o autocontrole dos indivíduos / Abstract: The expectation of this study is to exercise possibilities of analysis in the field of Education based on a strategic approach that, in addition to pointing to a possible theoretical path for the systematic study of forms of power that control, exploit, devastate, and exhaust the possibilities of education, make it possible to perceive how these forms of power are linked to a logic of global power. We opted to use interviews with mathematics professors who are in positions of authority in higher education institutions in the city of Maringá (PR). The method used was oral history, which enabled us to use memory more as a means of analyzing the actions governed by memory, and less for the knowledge it allows us to record. The interconnection between the theoretical and the methodological options in the study made it possible to articulate three elements we judge to be fundamental for understanding education as an instrument of distributing power and knowledge: the control of nature; social control; and individual self-control / Doutor

The diploma thesis ?Life and property rescue by IRS bodies on Lipno water reservoir? is divided into a theoretical and a practical part. The former describes the separate bodies of the IRS (Integrated Rescue System) designed for operations on the reservoir, their roles and equipment, and also gives a list of their protective and rescue devices along with examples of their use. This part of the thesis also explores drowning, rescue techniques for drowning people, and the physiological changes in their bodies caused by the effects of cold water. It also deals with the formation of ice and its properties, with the recovery of sunken vehicles, as well as with accidents threatening rescuers working in and under water. The practical part presents the process of preparation and implementation of a tactical rescue exercise of IRS bodies aimed at the recovery of a passenger car trapped under broken ice on Lipno reservoir in the municipality of Frymburk. The principal outcomes of the research are given in the conclusion of the thesis.
