Previous literature has indicated that nursing personnel face the second highest rate of occupational injury and illness. Assistive equipment, such as lift and transfer aids, has helped lower work task demands and reduce back stress on patient handlers. However, limited attention has been paid to the safety, comfort and dignity of the patient in postoperative care. Research on the efficacy of self-transfer aids for patients who require limited or no assistance by nursing personnel is insufficient. Ratings of comfort and security have only been evaluated for nursing home residents in a pilot field study, in which residents rated assistive devices as generally equal to or more secure and comfortable than manual transfer methods. The first study reports the laboratory evaluation of bed rising with the use of two self-transfer aids and bed rising unassisted. The objective was to determine muscle activity during bed rising tasks with and without the use of a bed assistive device using surface electromyography (EMG). Twenty male (n = 9; age, 33.7 ± 8.0 years) and female (n = 11; age, 34.5 ± 23.9 years) participants, with normal body mass index (BMI) ranging from 18.4 to 24.9, took part in the study. Mean and peak activity was recorded from three abdominal muscle sites. The results indicated bed rising with the use of a self-transfer device significantly reduced muscle activity compared to bed rising unassisted. Anchoring the devices at a higher height and elevating the torso further reduced muscle activity. Although no differences were observed between devices using EMG, results from the usability survey and final ranking indicated favorable ratings for the ABNOSTRAINTM prototype compared to the Bed Pull-up. A second study was conducted to determine the efficacy of a bed assistive device in a patient population. The objective was to compare self-perceived recovery measures and usage of pain medication between patients in the control (n = 8; age, 34.0 ± 6.3years) and device (n = 7; 40.7 ± 12.4) groups. A total of fifteen female participants undergoing either abdominal hysterectomy (n = 6) or Cesarean-section (n = 9) procedures were recruited for the study. Both groups completed a total of twelve questionnaires over a five-week recovery period. Responses to self-perceived recovery measures were significantly different. In general, the device group reported higher levels of energy, less pain interference, lower perceived pain, less reliance on pain medication and returned to activities of daily living faster than the control group. The results from the study provide clinicians or other practitioners information on the benefits of bed assistive devices for patients during postoperative recovery. Age and surgery differences should be considered when suggesting bed movement patterns with assistive intervention. / Master of Science

Thesis (MScEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2009. / This thesis details the development and comparison of two linear control systems that performhover control for a vertical take-off and landing unmanned aerial vehicle. A non-linear mathematical model of the aircraft dynamics is developed. A classical successive loop closure control approach is presented, which applies static gains to the decoupled model around hover. A variable gain approach is presented using optimal control, which linearises the aircraftmodel around its state at fixed time steps. Simulation performance and robustness results are examined for both systems. Different aspects of both controller design processes and results are compared, including navigational performance, robustness and ease of use.

Investigated representatives of three generations of 60 families living in Vilnius city and district and 10 experts working in city and district schools interviewed. There are analyzed understanding of empathy in our days society, practice of empathy rising in the historical and modern families, influence empathy rising of relationship and interaction features of different generations’ families members. The analysis results revealed that empathy approach to a variety of environment objects and ways and good teaching techniques of empathy-raising associated with human age groups, generations and interaction features of family members. Children and both groups of adults’ empathy commonly associate with condolence. Different age groups express empathy to different objects and prefer different empathy rising teaching techniques. Generally analogous empathy rising teaching techniques used in historical and modern families, but the context is adapted to modern society. Relationship and interaction of three generations family members are not discontinuous and allow transferring of existing traditions.

Hip Hop graffiti has been marking our urban landscapes for decades. However street art, a much less researched topic, has claimed notoriety in recent years. Much of the existing research groups hip-hop graffiti, gang graffiti and street art together and calls for a uniform response from communities, city officials and law enforcement. While street artists have made their mark in the urban landscapes of the United States as well as internationally, it is important to define the terms "street art"and "graffiti" and where they deviate from one another in order for cities to begin to address these expressions with any level of success. As municipalities grapple with visual public expression--street art and graffiti--a framework must be established taking into consideration legal parameters for both cities and artists.

A Star Called Henry (1999), do escritor irlandês Roddy Doyle (1958-), é o primeiro livro da trilogia The Last Roundup, cujo protagonista é Henry Smart. Este nasce em Dublin no início do século XX e desempenha papel importante na luta pela independência da Irlanda. Juntamente com os Irish Volunteers, Smart combate no Levante de Páscoa de 1916, auxilia na escrita da declaração de independência do país e torna-se soldado do Irish Republican Army (IRA) durante a Guerra da Independência (1919-1921). Henry é um herói, mas não do tipo clássico: filho de um assassino de aluguel e de uma adolescente pobre, Smart é ladrão desde os primeiros anos de vida e, durante suas lutas pela Irlanda, afirma não estar interessado no ideal nacionalista, uma vez que luta por dinheiro, comida e reconhecimento. Vivendo às margens da sociedade, Henry Smart desconstrói uma aura romântica em torno do Levante, da Guerra da Independência e dos heróis nacionalistas. O ponto de partida desta pesquisa é o questionamento sobre o impulso do autor em escrever um romance histórico em tempos de prosperidade financeira, pois Doyle publica a obra durante o período conhecido como Tigre Celta (1994-2008). Também questionamos por que o autor decide representar Dublin e os heróis nacionais de modo contrastante com o simbolismo nacionalista. Entendemos que o contexto de publicação do romance influencia a produção artística e, dessa forma, ao escolher a temática histórica, Doyle constrói uma crítica ao nacionalismo do início do século XX e também à sociedade do Tigre Celta. O autor entrelaça temporalidades a fim de expor as lacunas e inconsistências do passado e também do presente. / A Star Called Henry (1999), by the Irish writer Roddy Doyle (1958), is the first book of the trilogy The Last Roundup, whose protagonist is Henry Smart. He is born in Dublin at the beginning of the twentieth century and he plays an important role in the fight for Irelands independence. Along with the Irish Volunteers, Smart fights in the 1916 Easter Rising, helps to write the proclamation of independence and becomes a soldier of the Irish Republican Army (IRA) in the War of Independence (1919-1921). Henry is a hero, but not the classic kind: the son of a hired killer and a poor teenager, Smart is a thief since his early years and, when he fights for Ireland, he is not interested in the nationalist ideal, since he fights for money, food and recognition. Living at the margins of society, Henry Smart deconstructs the romantic aura around the Rising, the War of Independence and the nationalist heroes. The starting point of this research is to investigate the authors impulse to write a historical novel in times of financial prosperity, since Doyle publishes the book during the Celtic Tiger era (1994-2008). We also aim to understand why the author decides to represent Dublin and the nationalist heroes in a way that contrasts with the nationalist symbolism. We understand that the context of publication influences the artistic production, and, therefore, when choosing the historical theme, Doyle criticizes both the early twentieth-century nationalism and the Celtic Tiger society. The author intertwines temporalities in order to expose the gaps and inconsistencies of the past and the present.

La question de la remontée des niveaux marins et du recul du trait de côte est aujourd'hui une préoccupation de premier ordre face à laquelle les sociétés sont en attente de connaissances et de propositions. Or, les littoraux les plus menacés, les côtes basses, sont d'une part le siège de pratiques séculaires, de "défense contre la mer" et ont, d’autre part, été investis dans une période récente par des activités touristiques tournées vers l'exploitation des plages. Cette vulnérabilité physique et sociale explique notre choix pour les littoraux correspondants aux trois communes de Vias, Agde et Marseillan (golfe du Lion). Ces terrains réunissent un ensemble de caractéristiques qui en font un terrain laboratoire propice à l’observation et au traitement de cette problématique. L’érosion et la submersion marine ont marqué l’espace et les paysages de ces territoires. Face à cette situation de vulnérabilité se pose la question de l'adaptation des systèmes socio-économiques qui se sont développés dans ces espaces et de la résilience des territoires. La résilience désigne la capacité à anticiper, à réagir et à rebondir après un événement perturbateur. Cette approche nous permet de comprendre comment la société locale réagit face à des situations de vulnérabilité et comment se construisent les capacités d’adaptation et de résilience dans sa dimension territoriale. L’approche monographique est mobilisée dans notre travail à partir des entretiens semi-directifs, l’objectif est de confronter la notion théorique de la résilience des territoires à sa réalité pratique. À travers, ces trois territoires, il s’agit d’apporter des connaissances empiriques afin de décrypter les enjeux et révéler un modèle de développement axé sur la littoralisation des activités. Nous proposons à la fin de ce travail une nouvelle démarche, la Résilience Intégrée de Zones Côtières (RIZC), pour dépasser la complexité du réel et entretenir les solidarités entre tous les acteurs concernés. La RIZC permet de maintenir un niveau d’activité à l’aide des capacités de la souplesse du système afin de limiter les conflits d’intérêts entre public et privé et renforcer leur confiance mutuelle. / Rising sea levels and coastline recession have become a major issue about which society requires knowledges and solutions. The shorelines most threatened are low seacoasts which are both places of century-old traditions of coastal protection and localities exploited for tourism attracted by their beaches. This material and social vulnerability explains our choice of three municipalities: Vias, Agde and Marseillan (France, Gulf of Lion). These cases highlight features that permit pertinent observations on the subject. Erosion and coastal flood have shaped their landscape and planning. Can socioeconomics systems adapt to this new vulnerability? Resilience is the capacity to anticipate, react and bounce back after a disturbance. This approach allows us to understand how local communities react to vulnerability and plan new forms of resilience and adaptation. We use semi-structured interviews to build monographs and contrast theoretical resilience against real life experiences. These three territories are used to gather empirical knowledge in order to clarify the issues at stake and the need to abandon the concentration of activities on shorelines. Finally, we discuss how a new approach known as integrated coastal zone management; can overcome the complexity of the real situations encountered and underpin solidarity between all the stakeholders. Using a more versatile system, integrated coastal zone management, can help to maintain activities, limit conflicts of interest between public and private stakeholders and strengthen their mutual trust.

Les interactions entre des gouttes ou des bulles sont rencontrées dans de nombreuses applications industrielles et/ou environnementales. Ici, nous nous intéressons à l’électro-coalescence qui a des applications importantes comme par exemple la séparation eau/pétrole (coalescence de gouttelettes d'eau dans du pétrole). L’étude a été consacrée à l’élaboration et à la mise point de modèles basés sur les équations de Navier-Stokes et les équations régissant les champs électriques au niveau d’une seule goutte ainsi que l’interaction entre deux gouttes et plus particulièrement l’effet des forces hydrodynamiques et électrostatiques sur le mécanisme d’amincissement du film séparant les deux gouttes. Selon les cas traités, le suivi de l’interface est réalisé soit à l’aide de la méthode LS (Level Set) ou bien à l’aide de la méthode MM (Moving Mesh). Les solutions numériques ont été obtenues à l’aide du code de calcul COMSOL Multiphysics. Dans une première étape, nous avons analysé l’effet d’un champ électrique sur la déformation d’une seule goutte suspendue dans un autre fluide visqueux, pour différentes propriétés physiques et électriques des deux fluides. Le modèle a été testé et validé par confrontation avec les solutions analytiques existantes et avec des études numériques de la littérature. Nous avons examiné aussi l’influence du champ électrique sur la génération d’une goutte secondaire lors de la coalescence entre une goutte et une interface liquide-liquide déformable. Dans une seconde étape, nous avons étudié le drainage et la déformation de deux gouttes en interaction sous l’action d’une force constante. Contrairement à la théorie de lubrification basée entre autre sur l’hypothèse d’une petite déformation de l’interface, aucune hypothèse simplificatrice n’a été utilisée pour la résolution des équations, ce qui a permis d’obtenir des solutions numériques aussi bien pour les petites que pour les grandes déformations. Dans une troisième étape, nous avons examiné l’ascension d’une goutte isolée ou de deux gouttes de n-butanol dans l’eau sous l’influence de la force de flottabilité. L’évolution des vitesses terminales d’ascension des gouttes (goutte de tête/goutte suiveuse) et le drainage du film séparant les deux gouttes ont été analysées en présence et en l’absence de champ électrique. / Drops and bubbles interactions are encountered in various industrial and environmental applications. In this work, we focus on the electro-coalescence which has important industrial uses such as the destabilization of water / oil emulsions (coalescence of water droplets in oil). This study was devoted to the development and the elaboration of numerical models based on the Navier-Stokes equations and those describing the electrical field on a single drop as well as the interaction between two drops, and more particularly the effect of hydrodynamic and electrostatic forces on the thinning mechanism of the film separating the two drops. According to the treated cases, the interface tracking is achieved either by using the LS method (Level Set) or using the MM method (Moving Mesh). Numerical solutions were obtained using the commercial CFD software COMSOL Multiphysics. During the first step, we analyzed the effect of an electrical field on the deformation of a single suspended drop in another viscous fluid, for different physical and electrical properties of the two fluids. The model was tested and validated by comparison with existing analytical solutions and numerical studies found in the literature. We also analyzed the influence of the electric field on the generation of a secondary drop during the coalescence between a drop and a deformable liquid-liquid interface. In a second step, we investigated the drainage and deformation of two drops in interaction under the effect of a constant force. Unlike the lubrication theory which is based among others, on the assumption of a small interface deformation, in this work, no simplifying assumptions were used for the solution of equations, which allowed us to obtain numerical solutions for both small and large deformations. For the third step, we examined the rise of two drops of n-butanol in water under the influence of buoyancy force. The evolution of the drops terminal ascension velocity (leading drop/trailing drop), and the drainage of the film separating the two drops were analyzed in the presence and in the absence of electrical field.

L’objectif de la présente thèse est de proposer un cadre conceptuel d’approche desmouvements de population liés aux risques environnementaux. Depuis une vingtained’années, un ensemble de termes a émergé afin de caractériser ces populations: réfugiésenvironnementaux, éco-réfugiés, réfugiés climatiques, éco- migrant pour ne citer que les plusconnus. La caractérisation et le statut accordé à ces populations sont dépendants de la nature,la force et la rapidité de l’évènement environnemental contribuant à leur déplacement. Il estdonc indispensable de définir des critères précis pour éviter tout risque de confusion etprocéder à de véritables évaluations des flux liés à ces catastrophes. Notre analyse sefocalisera sur les risques liés à la hausse du niveau de la mer: risques de submersion etd’inondation sur le littoral et dans les espaces deltaïques. Face à ces risques croissants, il estimpérieux de mettre en place une «stratégie proactive», basée sur le triptyque protection -prévention et anticipation. Cette stratégie exige au-delà de la délimitation des zonesgéographiques concernées, une quantification et qualification des populations potentiellementtouchées. C’est la conjonction de deux formes de vulnérabilité qui est au coeur de notreproblématique: la vulnérabilité face aux risques d’inondations et la vulnérabilité face à lapression démographique croissante. C’est dans cet esprit que nous étudierons deux zonessoumises au risque d’inondation, l’une en France (Estuaire de la Gironde) et l’autre en Grèce(Deltas d’Axios-Loudias-Aliakmonas en Macédoine Centrale) afin d’estimer l’importanceéventuelle des mouvements de population à l’horizon 2025 et 2050. / The present thesis seeks to define a conceptual framework in order to examine the populationmovements related to environmental risks. For about twenty years, several terms haveemerged to describe thedisplaced people such as: environmental refugees, eco-refugees,climate refugees or eco-migrants. The terms and the status attributed to these populations arelargely dependent on the nature, strength and speed of the environmental event contributing totheir displacement. It is therefore necessary to specify the criteria in order to avoid anyconfusion and to be able to assess the physical flows generated by the environmentaldisasters. Our analysis is focused on the risks of submersion and inundation along the coastand in the delta areas associated with rise in the sea levels. In view of these increasing risks, it is absolutely necessary to set up a "proactive strategy", based on the triptych protection -prevention - anticipation. For each type of risk considered, this strategy requires, beyond thedelimitation of the geographical areas concerned, quantification and qualification of thepotentially affected populations. Consequently, the main aspect of our problematic combinestwo types of vulnerability:the firstdue to environmental disasters’ risks such as floods and thesecondto increasing population pressure. Finally, we chose to examine in our study two areashighly subjected to flood risks such as the Gironde estuaryin France and the Axios -Loudias-Aliakmonas Deltas in Central Macedoniain Greece trying to estimate the potential size ofpopulation movements in 2025 and 2050.

Cette thèse examine la « politique arabe » de la Turquie sous le règne du parti de la Justice et du Développement (AKP). Alors que pendant la majeure partie du XXème siècle la Turquie était désengagée du Moyen-Orient, les années 2000 voient une implication croissante d’Ankara dans son environnement régional arabe. Ainsi, cette thèse analyse le changement d’orientation qui a eu lieu en Turquie en matière de politique étrangère et de diplomatie à l’égard du Moyen-Orient. L’argument principal est que l’ouverture de la Turquie sur son environnement moyen-oriental est liée au phénomène de l’émergence : étant une puissance moyenne émergente en quête de statut, la Turquie de l’AKP trouve en le Moyen-Orient un champ de manœuvre indispensable pour son affirmation à l’échelle internationale. Nous avons examiné les outils et méthodes employés par la puissance moyenne émergente pour s’ériger en puissance régionale de son hinterland moyen-oriental, en particulier : le nouveau discours civilisationnel employé par l’élite au pouvoir, l’invention de «niches diplomatiques » comme la médiation et la diplomatie de la paix, le soft power comme outil de conquête des cœurs et des esprits, et la tentative de règlement de la question kurde. Toutefois, nous avons démontré que malgré le caractère «novateur » de ces instruments, le statut de la Turquie au Moyen-Orient reste fragile : d’une part, l’instabilité qui caractérise la région menace les acquis et les intérêts d’Ankara ; d’autre part, la Turquie souffre d’un « overachievement » ou d’un décalage entre ses ambitions de puissance et ses capacités et ressources réelles. Plus généralement, l’ « émergence» turque se heurte aux blocages du système international : la structure « oligarchique » de celui-ci empêche l’intégration des puissances moyennes en quête de statut et limite leur capacité d’influence dans le jeu de gouvernance mondiale. / This thesis examines the "Arab policy" of Turkey under the rule of the Justice and Development Party (JDP). While for most of the 20th century Turkey was disengaged from the Middle East, the beginning of the 21st century witnessed a growing involvement of Ankara in its Arab regional environment. Thus, this thesis analyzes the shift that took place in Turkey's foreign policy and diplomacy towards the Middle East. The main argument is that Turkey’s embrace of its Middle Eastern environment is linked to the phenomenon of “rising powers”: being a rising middle power in quest for status, Turkey has found in the Middle East a field maneuver necessary for its assertion on the international stage. The thesis examines the tools and methods used by Turkey to emerge as a regional power in its Middle Eastern hinterland, in particular: the use of a new civilizational discourse by the ruling elite, the recourse to "niche diplomacy" such as mediation and peace diplomacy, the use of soft power to win hearts and minds, and the attempts to solve the Kurdish question. However, it shows that despite the "innovative" character of these instruments, the status of Turkey in the Middle East remains fragile: on the one hand, the instability that characterizes the region jeopardizes the achievements and interests of Ankara; on the other hand, Turkey suffers from an "overachievement" or a gap between its ambitions and its power capabilities and real resources. More generally, Turkey’s quest for status is undermined by the structure of the international system: the "oligarchic" nature of the latter prevents the integration of middle powers and limits their capacity to play an effective role in global governance.
