Les cellules adhérentes, dont les cellules souches, sont très prometteuses pour de nombreuses applications dans le domaine des biotechnologies. Toutefois, leur culture représente un défi puisque les méthodes enzymatiques et mécaniques, couramment utilisées pour l’étape de détachement du support de culture, présentent des inconvénients majeurs. Le but de ce travail de thèse a été de développer un support pour la culture de cellules adhérentes permettant leur détachement par modification de la température. Pour cela, nous avons produit des échantillons thermo-associatifs de xyloglucane, un polysaccharide naturel, par réaction avec une enzyme, la ß-galactosidase. Les échantillons obtenus ont été caractérisés par rhéologie, viscosimètrie, diffusion de la lumière et chromatographie par perméation de gel. Nous nous sommes aussi intéressés à l’évaluation de méthodes de stérilisation efficaces capables de préserver les propriétés du polymère. De plus, afin de rendre ce polymère bioadhésif, nous avons étudié son activation et sa fonctionnalisation par un peptide contenant le motif arginine-glycine-aspartate (RGD). Nous avons montré que des cellules modèles A375 surexprimant le récepteur pour le RGD sont capables d’adhérer et de proliférer à 37°C sur des films formés à partir de xyloglucane modifié par du RGD. Leur détachement est possible à température ambiante. L'utilisation de ce nouveau support pour la culture de cellules souches embryonnaires humaines, la production d’un système pour la libération contrôlée de facteurs de croissance ainsi que la conception de billes de taille micrométrique à base de xyloglucane font partie des perspectives de cette thèseAdherent cells, including stem cells, hold great promise for many applications in biotechnology. However, cell detachment from standard culture surfaces remains a challenging task since both commonly used enzymatic and mechanical methods have major drawbacks. The aim of my PhD work was to develop a thermoresponsive culture surface supporting cell attachment and survival while enabling a temperature-assisted cell detachment. In order to achieve this goal, thermoresponsive xyloglucan was initially produced by partial galactose removal after reaction with the β-galactosidase enzyme. Samples were characterized by rheology, viscosimetry, light scattering analysis and size-exclusion chromatography. We were also interested in evaluating sterilization methods and their effect on the properties of the polymer. Additionally, in order to obtain a bioadhesive polymer from partially degalactosylated xyloglucan, we studied its functionalization with a peptide containing the arginine-glycine-aspartate (RGD) groupment motif. We have shown that A375 model cells overexpressing the RGD receptor were able to adhere and proliferate at 37 °C on xyloglucan-derived films grafted with RGD and their detachment at room temperature was also demonstrated. The culture of human embryonic stem cells, as well as the introduction of a controlled release system for growth factors and the development of thermoresponsive beads for cell culture comprise the perspectives of this thesis

Les propriétés de rétention et de circulation de l'eau et de l'oxygène dans les supports de culture présentent de fortes particularités qui sont liées à un volume réduit de substrat (pot, conteneur), dans lequel les biodisponibilités hydrique et gazeuse fluctuent fortement et rapidement au cours de la journée. Afin d'optimiser les apports d'intrants aux besoins de la plante, tout en limitant les rejets vers l'environnement, il est nécessaire d'améliorer la compréhension des processus de transfert de matière dans les substrats au voisinage des racines. Dans cette optique, nous nous sommes tout d'abord attachés à mesurer et à comprendre l'impact des propriétés physiques de deux matériaux organiques modèles (tourbes blondes et écorces de pin compostées) sur les processus de transfert de matière, au cours d'un cycle de dessiccation-réhumectation. Cette étude préalable, a permis de proposer un modèle de fonctionnement hydrostructural des matériaux organiques. Nous avons pu notamment mettre en évidence que l'hystérèse des propriétés de surface des matériaux organiques (variation de la mouillabilité en fonction de l'état hydrique) pouvait expliquer l'hystérèse des caractéristiques hydrique et hydrodynamique de ces milieux poreux. La déformation des matériaux va également influencer les propriétés de rétention et de transfert d'eau et d'air dans le milieu. Ces modifications, qui se déroulent dans les états hydriques les plus forts, vont faire intervenir des processus hydrostructuraux différents suivant que l'on s'intéresse à la tourbe (déformation élastique totalement réversible) ou aux écorces (déformation plastique partiellement réversible). Nous avons pu également définir des gammes “optimales” de potentiel hydrique ou de teneurs en eau (où les flux d'eau et d'oxygène dans ces deux substrats sont très élevés) bien différentes des seuils empiriques de -1 kPa et -10 kPa, encore aujourd'hui utilisés pour la gestion de l'irrigation dans les cultures en pots et conteneurs. Afin de représenter l'effet des propriétés préalablement définies sur les biodisponibilités en eau et en oxygène reliées aux besoins de la plante, nous avons ensuite intégré ces propriétés dans un modèle monodimensionnel de transfert couplés d'eau et d'oxygène au voisinage des racines (fonction puits racinaire) et à l'échelle journalière. Cette approche modélisatrice a permis de mettre en évidence qu'il était difficile de réunir sur une journée de culture, et sur une gamme apparemment optimale de potentiel hydrique, en même temps des conditions de teneurs en eau et en oxygène non limitantes pour la racine. Ces résultats ont été obtenus quels que soient le substrat considéré et les états hydriques initiaux fixésDistribution and movement of liquids and gases in growing media present high specificity due to the limited volume of susbtrate (for roots fonctioning) in which water and oxygen availability highly fluctuate over a short period of time. In order to optimize management of fertigation and for subsequent plant growth in soilless culture production, it is still necessary to improve our knowledge of transfer properties (water and oxygen) at the substrate-root interface. In this context, we first precisely studied the influence of the physical properties of two organic materials model (Sphagnum peat and composted pine barks) on the dynamic of water and oxygen, during a drying-wetting cycle. A hydrostructural model was proposed for these two organic materials. We showed that hysteresis phenomena observed in the surface properties (evolution of wettability related to water potential) could be associated with hysteresis phenomena observed in the hydraulic characteristics of these porous media. The deformation of materials also influence retention and transfer properties of water and air in the substrates. Modifications of the solid phase, which occured near saturation, underline different hydrostructural behaviour depending on whether peat (elastic, reversible deformation) or barks (plastic, partly irreversible deformation) is considered. "Not-limiting" range of water potential (corresponding to high oxygen and water flows in substrates) were determined, and results obtained are quite different from the empirical thresholds of -1 kPa and -10 kPa, still used for the management of fertigation in soilless culture production. In order to represent the effect of all properties beforehand define on oxygen and water availability related to the physiological needs of the plant, we embed these properties in a one-dimension transfer coupled model of water and oxygen in the root vicinity and on a one-day time scale. If one replaces in the "not-limiting" range of water potential, our model underline that it is difficult to maintain during one day of culture, at the same time, water and oxygen content conditions not limiting for the roots. These results were obtained whatever the substrate and the water content considered

Corruption and unethical management is a legitimate global economic concern as it can have a direct and substantial impact on the longevity and the economic success of an organisation, an industry and a country. As a result of individuals having more readily available access to information, much attention has been given to unethical behaviour and organisational ethical violations over the last decade. Recent events have indicated that business ethics is an organisational concern with mammoth implications for business. For example, Esterhuyse (1999, p. 27) reports that South Africa has lost astronomical amounts of money due to office or white-collar crime. Organisations’ attempts to become globally competitive will be hampered by the behaviour of employees who are unethical at work. Therefore, it is imperative that organisations implement measures to increase ethical awareness and behaviour in their employees. This research study deals with business ethics in the automotive cluster of the Eastern Cape Province and proposes a model that can assist an organisation in improving its ethical culture. The main question that this research study addressed was: To what extent do the strategies of human resource departments contribute to establishing and maintaining an ethical organisational culture? To answer the above question it was necessary to address the most universal characteristics of ethical organisations. To this end the role of the human resource department in attempting to develop and sustain an ethical organisational culture is discussed. Thereafter, various ethical models are outlined and evaluated. Lastly, the proposed ethical model for establishing an ethical organisational culture is presented. Based on the theoretical findings of the literature survey which outlined the characteristics of ethical organisations and the interventions required to improve the ethical functioning of an organisation, a questionnaire was developed and distributed to organisations within the automotive cluster in the Eastern Cape Province. The empirical results obtained from the survey indicated dominant consensus regarding the model (see Chapter Four). The main findings from this research are that 74.7 per cent of organisations that participated in the empirical study had implemented a code of ethics. However, the majority of these organisations had not implemented the identified critical and optional interventions (see to Chapter Four) required to operate as an ethical organisation. The study also revealed that 49.4 per cent of respondents believed that the human resource manager is responsible for organising and coordinating an ethical initiative within the organisation. Respondents in this study stated that the benefits of operating ethically are the improved financial position of the organisation (76.5 per cent), the enhanced morale of employees (95.3 per cent), positive stakeholder perception (93 per cent), better long-term strategic sustainability (94.3 per cent) and superior social responsibility (85.9 per cent).

En culture hors-sol, une gestion raisonnée de l’eau est nécessaire pour augmenter le rendement d’une culture. Les propriétés de rétention en eau et en air des substrats horticoles sont étroitement liées à la morphologie des particules, elle conditionne leur arrangement duquel se dessine un espace poral composant au moins 85% du volume. La morphologie détaillée des particules n'a jamais été réellement étudié pour les substrats horticoles, en partie parce que l’analyse est complexe, en raison de la grande diversité des tailles et des formes des particules. Seul le tamisage a été utilisé pour caractériser les particules, cependant cette méthode rencontre beaucoup de limites (imprécise, peu informative, pas adaptée à toutes formes de particules). Pour détailler les liens entre propriétés physiques et morphologie des particules, les recherches présentées reposent sur l’utilisation de l’analyse d’images dynamique, offrant des résultats plus précis et détaillés. Diverses mesures de répartitions granulométriques et de propriétés physiques sur une grande diversité de matériaux, ont été effectuées. Les résultats révèlent une très grande diversité des tailles et des formes des particules au sein de chaque matériau. La morphologie des particules peut être résumée par leur circularité et leur longueur. Plus la taille des particules est petite, plus le substrat est composé de pores fins, plus retient d’eau, et inversement moins d’air. Aussi l’évolution de la structure du matériau est impactée par les particules fines. Finalement, la longueur moyenne des particules est un bon estimateur de ses propriétés physiques. Ces travaux donnent des clés aux fabricants de supports de culture pour mieux designer leurs matières et encouragent à caractériser les propriétés physiques par l'étude de la morphologie des particulesIn soilless culture, a wise management of water is necessary to increase the yield of a crop. The water and air retention properties of horticultural substrates are closely linked to the morphology of the particles, which determines their arrangement and from which a pore space is formed that makes up at least 85% of the volume. The detailed morphology of the particles has never been really studied for growing media, partly because the analysis is complex, due to the great diversity of particle sizes and shapes. Only sieving has been used to characterize the particles, however this method has many limitations (inaccurate, not very informative, not adapted to all particle shapes). In order to detail the links between physical properties and particle morphology, the presented research relies on the use of dynamic image analysis, offering more precise anddetailed results.Various measurements of particle size distributions and physical properties on a wide variety of materials have been performed. The results reveal a very large diversity of particle size and shape within each material. The morphology of the particles can be summarized by their circularity and length. The smaller the particle size, the more fine pores the growing media has, the more water it retains, and conversely the less air. Also, the evolution of the material structure is impacted by finer particles. Finally, the mean length of the particles is a good estimator of its physical properties. This work gives growing media manufacturers keys to better design their materials, and encourages to characterize the physical properties by studying particle morphology

« L’utilisation des séries judiciaires télévisuelles pour l’enseignement de l’anglais juridique : étude des séries américaines et anglaises comme support pédagogique. » Cette étude est le résultat d’un projet de recherche sur la possibilité d’exploiter les séries judiciaires anglaises et américaines comme outils pour l’enseignement de la culture et du langage juridiques anglo-saxons à des étudiants en droit. L’objectif étant essentiellement de comparer deux pays de même tradition juridique pour mettre en exergue leurs différences culturelles nationales. La base théorique de cette analyse se trouve dans le champ des cultures juridiques et dans les séries judiciaires ainsi que dans la méthode "Silent Way". Il s’agit de montrer comment ces programmes de télévision créent un environnement qui encourage les étudiants à acquérir une meilleure connaissance du système de common law ainsi que du langage juridique anglais, et ce de manière autonome et en déployant peu d’énergie. Une brève description d’une expérience visant à utiliser ce type de séries télévisées dans le contexte d’un enseignement universitaire d’une part et une étude menée auprès d’un certain nombre de professeurs d’anglais juridique en France d’autre part, ont permis de vérifier que l’utilisation de ces séries et de ces films comme supports pédagogiques suscitait un vif intérêt. Les données extraites des séries anglaises et américaines étudiées ici, ont été analysées avec une approche comparative empirique qui a permis de mettre en lumière des similitudes et des différences notamment dans les professions juridiques et dans les rituels des tribunaux de ces deux pays régis par la "common law"< Using courtroom dramas in teaching legal English: studies of American and British series as pedagogical materials > is the result of a research project on the exploitability of British and American television procedurals as tools for teaching English legal language and culture to law students, especially with a view to comparing these two countries belonging to the same legal tradition and highlighting national cultural differences. The theoretical basis for this analysis resides in the field of legal cultures and legal series as well as the pedagogical approach of the "Silent Way" in order to show how these programmes create an environment that encourages students to acquire knowledge of common law culture and legal English in an autonomous and economic way. A brief description of an experience using such shows in the context of a university course and a survey conducted with a number of legal English teachers in France, confirmed a significant interest with regarding the use of series and films as teaching aids. The data found in the English and American series of the corpus studied here, is analysed through an empirical comparative approach which reveals similarities and differences with respect to such aspects as the legal professions and courtroom ritual in these two common law countries

La connaissance précise au fil du temps des propriétés physiques du milieu de culture d’un végétal est importante pour une gestion efficace de l'irrigation et de la fertilisation. Ce travail est consacré a l’évaluation des évolutions hydriques (rétention en eau), structurales (retrait/gonflement) et superficielles (mouillabilité) des matériaux organiques utilisés comme supports de culture pendant plusieurs cycles de dessiccation et ré-humectation. Un effort de développement expérimental important a porté sur la mise au point de méthodes permettant de mesurer simultanément et en continuité les variations de déformation volumique (retrait/gonflement) du massif et de ses propriétés de rétention en eau. Trois matériaux, tourbe blonde de sphaigne, tourbe noire et fibre de coco ont été testés avec des contraintes hydriques atteignant -32 kPa. Les courbes obtenues montrent une évolution importante du volume du massif au cours du cycle de dessiccation et ré-humectation, les 2"’ et 3' Cycle sont répétitifs et superposables. L’intensité de la dessiccation appliquée a un effet important sur les propriétés de rétention en ré-humectation dans le cas des tourbes blondes de sphaigne ; il est peu perceptible pour la tourbe noire et la fibre de coco. Tous les matériaux testés montrent un caractère biporal très marqué avec une première porosité inter-grain ou inter-fibre se vidant autour de -lkPa et une porosité intra-grain plus variable en fonction des matériaux, de -15kPa pour la tourbe blonde a -40kPa pour la tourbe noire. Le caractère hydrophobe des matériaux au cours de la dessiccation a été évalué avec deux méthodes : ascension capillaire et goutte posée. Une approche méthodologique a permis de mettre en correspondance ces deux approches et d’expliquer leurs différences. Pour tous les matériaux, la mouillabilité varie surtout en fonction de l’humidité de matériau. Le retour a un caractère hydrophile avec la ré-humectation est variable et fonction des matériaux, rapide et réversible dans le cas de la fibre de coco, il est plus lent dans le cas des tourbes. Si les phénomènes dits « de bouteilles d’encre » restent probablement prépondérants pour expliquer l’hystérèse des propriétés de rétention dans les états les plus humides, l’utilisation d’un modelé biporal de type van Genuchten et introduisant un angle de contact en ré-humectation a permis de montrer que dans les dessiccations les plus poussées, l ' hydrophobie peut expliquer la plus grande partie des phénomènes d’hystérèseThe precise knowledge over time of physical properties of a plant roots environment is important for the effective management of irrigation and fertilization. This work is devoted to the assessment of the variations in water retention, shrinkage/swelling and wettability of organic materials used as growing media during several drying and resetting cycles. An important effort is done to develop the methods used to measure simultaneously and continuously the changes in volumetric deformation of the massif (shrinkage/swelling) and its water retention properties. Three materials, sphagnum peat, black peat and coco coir were tested with suction up to -32 kPa. The curves obtained show an important evolution during the first drying and rewetting cycle, however the second and third cycle is repetitive and superimposed. The drying intensity has the impact on the irreversibility of water retention measured on peat, however it is not very perceptible with black peat and coco coir. All materials tested showed a double porosities character with a porosity inter-fiber or inter-grain emptied around -1 kPa and another porosity intra-grain with the air entry pressure variable depending on materials, -15 kPa for blond peat and -40 kPa for black peat. The water repellency of material during the drying was assessed with two methods: sessile drop and capillary rising methods. This methodological approach allows finding out their correspondence and difference. The variation of wettability depends mainly on the humidity of material. If the effect of “ink bottle” is probably crucial in explaining the hysteresis of water retention properties in the most wet states, using a bimodal model of van Genuchten introduced a contact angle in resetting has shown the water repellency can explain the hysteresis in the case of more intense drying suction

Les cellules souches mésenchymateuses (CSM) ont un fort intérêt en utilisation clinique. Leurs différentes caractéristiques telles que leurs propriétés immuno-modulatrices, leur capacité à se différencier, et aussi la sécrétion de facteurs, sont nombreuses et prometteuses pour le traitement clinique de maladies où peu de thérapies sont proposées ou sont peu efficaces. Cependant, les doses à injecter pour des résultats cliniques significatifs doivent être répétées et contiennent généralement des quantités importantes de cellules (106 cellules kg-1 par patient). Ainsi, des méthodes de production à grande échelle doivent être mises en œuvre pour répondre à la demande, tout en minimisant les coûts de production. Dans ce travail de thèse, une première étude a permis de comprendre une partie des mécanismes d’interaction des cellules avec leurs supports de croissance, les microporteurs. Le temps d’adhérence et des migrations cellulaires entre microporteurs ont pu être mesurés et étudiés. Une stratégie d’ajout de microporteurs à des temps spécifiques de la culture a été proposée. Suite à cela, la deuxième partie d’étude de ces travaux a été de déterminer les performances d’expansion du procédé réalisé à plus grande échelle (1.5 L), en utilisant des microporteurs innovants développés par les équipes partenaires du projet européen, et présentant des chimies de surfaces variées. Plusieurs microporteurs candidats se sont révélés prometteurs pour l’expansion des cellules souches de la gelée de Wharton. Enfin, la dernière partie de la thèse a été consacrée au développement d’un procédé innovant reposant sur le soutirage de microporteurs vides, diminuant le risque de frictions délétères entre des microporteurs très concentrés, a été proposé. De plus, un contrôle en ligne de la concentration en cellules vivantes a été effectué dans le bioréacteur à cuve agitée. Des microporteurs commerciaux innovants, solubles sous l’action d’enzymes, ont été utilisés dans cette dernière partie. Une amélioration du facteur d’expansion (d’un facteur 1.5) a été obtenue par l’utilisation de ce mode continu et perfusé en bioréacteur. De plus, ces microporteurs, solubles sous l’action d’enzymes, ont permis un excellent rendement de détachement cellulaire, élément essentiel pour envisager l'utilisation des CSMs en thérapie cellulaire à un coût contrôléMesenchymal stem cells (MSCs) show great interest in cellular therapies. Their various characteristics such as their immuno-modulatory properties, their ability to differentiate, and also the secretion of factors, are numerous and promising for new clinical treatments for diseases where few therapies are proposed or have few efficiencies. The doses to be injected for significant results must be repeated and generally contain high quantities of cells (106 cells kg-1 per patient approx). Large scale production methods must be implemented to meet the demand, and in the least costly way possible. In this PhD work, the main objective was to develop a scalable process adapted to these support-dependent cells. For this end, a first study allowed to understand part of the mechanisms of interaction of cells with their growth supports, the microcarriers. The adhesion time but also the cell migrations between microcarriers were characterized and evaluated. A strategy of fed-batch mode strategy with microcarriers addition at specific times in the culture was also proposed. Following this, the second part of the study of this work was to determine the efficiency on larger scale expansion process (1.5 L), using of innovative microcarriers developed by the partner teams of the ‘ImprovesStem’ European project. Several microcarriers candidates with chemically modified surface proved to be promising for the expansion of Wharton’s jelly stem cells. Finally, in the last part of the thesis, an innovative process based on the removal of empty microcarriers, avoiding the risk of deleterious frictions between highly concentrated microcarriers was proposed. Moreover, an on-line monitoring of viable cell concentration was carried-out in the stirred tank bioreactor. Innovative commercial microcarriers, soluble under the action of enzymes, were used in this last part of the study. An improvement of the expansion factor (by a factor of 1.5) was obtained in this continuous-perfused mode of culture in the stirred bioreactor. In addition, these enzymatically-soluble commercial microcarriers allowed for an excellent detachment yield, essential to consider their use in cell therapy

Nous avons étudié les interactions (en terme de morphologie, croissance et attachement) de cinq types cellulaires sur des microsupports bio-spécifiques, dotés de propriétés heparin-like, dérivés du polystyrène: le polystyrène sulfonate hautement substitué et le polystyrène sulfamide d'acide aspartique à différents taux de substitution en acide aspartique. Nous constatons un effet de la composition du microsupport. Cet effet n'est pas identique sur tous les types cellulaires. Certaines cellules sont influencées par la présence de groupements carboxyles (mccoy et eahy926) ou sulfonates (rinm5f et mcf-7), ou par le taux de substitution en groupements carboxyles (mccoy et mcf-7). D'autres cellules se comportent de façon identique sur tous les supports (hbl100). Dans tous les cas, l'adsorption de différentes protéines sur la surface du microsupport ne modifie pas la prolifération cellulaire. Nous retrouvons un effet d'inhibition de la croissance des cellules mccoy par des dérivés polystyrènes hautement substitués par l'acide aspartique et qui est identique à celui obtenu sur les cellules endothéliales du cordon ombilical humain. Cependant, de façon générale, la croissance cellulaire est dépendante des protéines fournies par le sérum, puisque la croissance de la plupart de cellules diminue dans un milieu déficient en sérum. La présence des anticorps anti-fn dans le milieu de culture ou sur le support montre que la fibronectine intervient, mais avec d'autres protéines, comme médiateur dans la prolifération cellulaire. L'effet n'est pas identique pour toutes les lignées cellulaires. Au niveau de l'attachement cellulaire, la fibronectine intervient dans l'attachement de certaines cellules. Néanmoins, il est clair que plusieurs mécanismes interviennent dans les interactions des cellules avec les différents supports. Plusieurs protéines semblent être impliquées.

School culture develops as staff members interact with each other, the students, and the community. It becomes the guide for behavior shared among members of the school at large. School culture is a self-repeating cycle; culture is shaped by the interactions of the personnel, and the actions of the personnel become directed by culture (Hinde, 2004). The culture of a school can be a positive influence on student learning or it can inhibit the functioning of the school. Stakeholders in any environment prefer to be in a situation that is appealing and welcoming. When students attend school, the expectation is that it is a place where they like to be, a place that offers support and encouragement, and a place where physical comfort levels are optimal (MacNeil, Prater, & Busch, 2009). Research indicates school culture plays a significant role in educational reform efforts (Gruenert & Whitaker, 2015).
This study investigated how perceptions of teachers, support staff, and administrators affect school culture and academic achievement, and aimed to define how Social-Emotional Learning (SEL) impacts school culture. The data collected and the statistical tests performed included Correlations, a Mann-Whitney Test, and a One-way Analysis of Variance (ANOVA). The SCS-FF Open-ended responses were coded and synthesized, and interviews with six certificated employees were coded and categorized into nine themes divided into four meta-codes. Lack of implementation with fidelity and consistent progress monitoring of the PBIS program suggests that there is a lack of cohesiveness shared among staff members at XYZ K-8 School. Consistent expectations for all stakeholders, set forth by administration, emerged as imperative to program success and a positive school culture.

Cette étude a permis de mettre en évidence quelques paramètres physico-chimiques qui ont une influence sur la croissance cellulaire, le taux de reprise et la densité cellulaire à la confluence des cellules de lignées épithéliales de foie de rat propagées dans des boîtes de Cooper et dans des biogénérateurs dans des milieux contenant du sérum, sans sérum complétés par de l'albumine et totalement synthétique et aprotéique. La densité cellulaire inoculée, le type de microsupport utilisé et les conditions d'attachement des cellules affectent la croissance cellulaire dans les milieux contenant du sérum. Dans ce même milieu, les cellules synthétisent des facteurs qui agissent sur leurs propres mitoses déterminant la façon de renouveler les mileux dans les biogénérateurs pour que la croissance cellulaire soit maximum. Un système d'oxygénation composé d'un tube de silicone enroulé dans le biogénérateur de 2 L dans lequel peut circuler de l'air ou de l'oxygène permet un apport d'oxygène dissous efficace dans le milieu. Cet apport d'oxygène a pouir effet d'augmenter la densité cellulaire et de réduire la consommation de glucose et la production d'acide lactique par les cellules. Des effets favorables sur la croissance cellulaire ont été constatés en remplaçant dans le biogénérateur le milieu synthétique de base F10 de HAM par le MEM de DUBELCCO dans les conditions de culture sans sérum en présence d'albumine. Dans les conditions de culture sans sérum et sans protéine, cet effet favorable a été constaté aussi bien dans les boîtes de culture que dans les biogénérateurs. Pour induire l'attachement cellulaire dans ces deux conditions de culture sans sérum, l'utilisation de milieu usagé soit mélangé au milieu frais soit comme moyen de remplacement du sérum, pour le prétraitement des substratums a permis d'omettre l'addition des facteurs sériques et le prétraitement des surfaces de culture par du sérum. De même, la trypsine n'est pas nécessaire pour les repiquages dans les conditions de culture dans un milieu synthétique aprotéique dans les boîtes de Cooper car elle peut être remplacée par l'utilisation de citrate trisodique. Ce travail ouvre des perspectives à l'échelle industrielle, dans des conditions de culture économiquement rentables, de cellules dépendantes d'un support cultivées dans des milieux totalement dépourvu de sérum.

This practice-led study assumed a teaching artist perspective to conceptualise how Arts and Design-Based Inquiry (ADBI) supports leaders to design strategy, as a participatory process of intentional organisational change, suited to complex and rapidly changing business contexts. Aesthetic Literacy was introduced as a core competency and was found to be critical to innovative culture and how to design experiences. Senge’s learning organisation model was applied to understand how to develop innovative organisational culture through mechanisms of change such as individual and collective mindset, Why, conversation, and learning. An ADBI Framework for designing strategy is presented.

Vanhée, Loïs. "Using culture and values to support flexible coordination." Thesis, Montpellier, 2015. http://www.theses.fr/2015MONTS258/document.
Повний текст джерелаАнотація:
Cette thèse propose une méthode pour coordonner flexiblement des Systèmes Multi-Agents (SMA). Plus en détails, nous étudions comment influencer des agents artificiels afin que, collectivement, ils atteignent des objectifs complexes et/ou dynamiques dans des environnements eux-aussi complexes et dynamiques (ex: un groupe de robots pour secourir les victimes lors d'un désastre, qui peut s'adapter à une grande variété de dangers, conditions climatiques, état des victimes).Dans ce but, nous avons d'abord étudié pourquoi, dans les sociétés humaines, les humains parviennent à coordonner relativement flexiblement mais pas leurs contreparties artificielles (agents des SMA). Cette opposition peut être grandement expliquée à l'aide d'un facteur clef : la culture. Les humains qui partagent un même bagage culturel se coordonnent flexiblement plus facilement, car ils ont une idée commune de ce que "travailler ensemble" veut dire. A contrario, les agents n'ont pas ce bagage et leurs échecs pour travailler ensemble s'apparente souvent à des chocs culturels.Ainsi, notre objectif consiste à répondre à la question suivante: peut-on utiliser une culture semblable à celle des humains comme un outil coordonner les SMA (et si oui, comment) ? Pour répondre à cette question, il nous faut d'abord expliquer : comment intégrer une culture semblable à celle des humains dans un SMA? Cette seconde question en soulève une troisième à étudier en premier : comment est-ce que la culture influence la manière dont la coordination se passe dans les sociétés humaines ?1- Nous montrons que de manière générale, la culture influence les décisions individuelles prises en situation d'interaction (ex: au travers d'attentes, de manière d'agir et de raisonner). Cette influence mène à l'occurrence de schémas d'interaction abstraits, récurrent et cohérents, qui, généralement, améliorent la performance collective. Ensuite, nous spécifions comment les principaux mécanismes l'influence connue de la culture (ex: importance culturelle accordée au pouvoir, aux règles) appliquent spécifiquement en situation de coordination (ex: la culture influence si les dirigeants donnent des ordres vs. des propositions à leurs subordonnés).2-Nous montrons comment répliquer les mécanismes l'influence de la culture sur la coordination dans les SMA. Tout d'abord, puisque la culture est fondée dans les décisions individuelles, nous mettons en avant un mécanisme de décision humain clef qui, à la fois, est sensible à la culture et influence la coordination. Ce mécanisme se trouve dans les valeurs, ce que les gens considèrent comme "bien" ou "important" (ex: honnêteté, discipline, autonomie). Ensuite, nous intégrons ces valeurs dans une architecture agent capable de prendre des décisions en situation de coordination. Enfin, nous illustrons que notre architecture peut en effet reproduire l'influence de la culture sur la coordination à travers de deux simulations qui répliquent des phénomènes culturels en situation de coordination connus.3-Nous étudions comment ces valeurs, inspirées des valeurs humaines, peuvent être utilisées coordonner des SMA. Tout d'abord, nous étudions pour quels problèmes les valeurs offrent un moyen opérationnel pour soutenir la coordination. A l'instar des sociétés humaines, les valeurs sont particulièrement offrent un haut niveau de flexibilité, quand les agents doivent raisonner eux-même pour établir une coordination. Puis, nous étudions les détails techniques à considérer pour utiliser en pratique des valeurs pour coordonner flexiblement des SMA (ex: quelles valeurs choisir ? Comment les représenter ?).En résumé, cette thèse met en évidence que les principaux mécanismes de l'influence de la culture sur la coordination (en particulier, grâce à l'influence de la culture sur les valeurs) peuvent être répliquées au sein des SMA. De plus, nous montrons que ces mécanismes peuvent être manipulés dans le but de coordonner des SMAThis thesis proposes a method for supporting flexible coordination in multi-agent systems (MASs). In other words, we aim at influencing societies of artificial agents such that they can handle complex or evolving environments and collective goals (e.g. robots providing an emergency support capable of handling various hazards, climatic conditions, status of victims).Towards achieving this goal, we first investigated why in human societies, for which MASs can be seen as an ``artificial" counterpart, humans manage to coordinate relatively flexibly comparatively with artificial agents in MASs. We discovered that culture is a key factor of this relative success. Briefly, when humans share a cultural background, they manage to coordinate more flexibly because they share a common idea about what ``working together'' means. Conversely, artificial agents miss this aspect, leading in turn to coordination failures that can are similar to cultural clashes.The lack raises our goal: we want to better understand how culture can be integrated within and used for coordinating artificial societies. This goal raises the following research question: (how) can human-like culture be used as a tool for supporting coordination in artificial societies? As a preliminary step for answering this question, we need first to answer this question: (how) can the influence human-like cultures be integrated within artificial societies? In turn, this question raises a third one to be answered first: how does culture influence coordination in human societies?As a first step, we expand general theories of culture for conceptualizing its influence in the context of coordination. From a generic perspective, we explain that culture influences individual decisions that support matching expectations and coherent interaction patterns, leading in turn to (generally) better collective performance. From a more specific perspective, we specify how the core acknowledged patterns of the influence of culture (e.g. cultural importance given to power status, to rules) apply in the context of coordination (e.g. culture influences the likeliness that leaders are (made) responsible for making decisions for subordinates vs. proposing alternatives).As a second step, we study how to replicate human-like influences of culture on coordination within artificial societies. First, since culture is grounded within individual decisions, we investigate the core culturally-sensitive decision aspects that impact the most (flexible) coordination in human societies. We discover that values, what people consider as ``good'' or ``important'' (e.g. honesty, obedience, autonomy), constitute such an aspect by deeply supporting a wide range of (interaction-related) decisions. Then, for illustrating how to replicate influence of culture within artificial societies, we build an value-sensitive agent decision architecture that can make coordination-related decisions. Finally, we illustrate that our architecture can replicate the influence of culture on coordination through two simulations that replicate known coordination-related cultural phenomena.As a third step, we study how human-like values can be used for supporting coordination in artificial societies. First, we investigate the range of coordination problems for which values can offer an operational means for supporting coordination. As in human societies, values are particularly adequate for problems with complex and dynamic environments, requiring agents to make coordination-related decisions. Then, towards concretely implementing values, we study the technical details to consider when using values for supporting flexible coordination (e.g. how to concretely design values and integrating them within decision processes)

This thesis will report on mixed method research which examined secondary Support Teachers Learning Difficulties (STLDs) and their modes of operation in New South Wales (NSW) government schools, Australia. Four modes of operation were identified in the literature as consultancy, team teaching, in-class support and withdrawal. An additional area of other duties was also included to examine the time when STLDs were not functioning in the four identified modes of operation. NSW government policy is in keeping with the literature as it recommends that STLDs should spend the majority of their time in consultancy and team teaching while in class with a minimum of withdrawal of students from their main classrooms for individual or small group instruction. STLDs, however, did not appear to be functioning in the recommended way. A number of factors identified in the literature, which may influence the modes of operation, can be grouped under the heading of school culture thus this research involved the examination of the effects of school culture on the modes of operation with the aim of expanding our understanding of the functioning of STLDs and providing suggestions for improvement. The theoretical base of social constructionism has informed this research which included survey and case study methods. Case studies of the STLDs in three secondary schools led to the conclusion that, in conjunction with factors such as flexibility and commitment, the involvement of the STLD in a sub-culture of learning support may lead to functioning in the recommended modes of operation.

This thesis examines the idea that police officers have supportive factors in their lives which influence coping mechanisms used to handle occupational stress. This idea comes from police culture literature which suggests that officers are encouraged to use maladaptive coping strategies like drinking and emotional suppression to deal with stress. Additional research on management support and family support are introduced as alternative supportive factors which can promote the use of adaptive coping like agency offered services and programs. This thesis uses data from “Work and Family Services for Law Enforcement Personnel in the United States” (Robert, O’Quin, & Kennedy, 2000). A subset of questionnaire items and officer responses are coded and run through statistical analysis including linear regression and logistic regression. Finally, findings are discussed and future research on the topic is suggested.

Les travaux présentés relatent la mise au point d’un procédé d’épuration aérobie en lit immergé par bactéries fixées sur support géotextile. Ce matériau facilite la réalisation et l’exploitation des installations par rapport aux lits immergés granulaires. La bibliographie et les expériences préliminaires menées sur différents géotextiles démontrent que les critères de choix pour les matériaux de fixation sont indissociables de leur mise en œuvre. Pour la suite de cette étude le géotextile ENKAMAT et utilisé. La colonisation du support sélectionné est réalisée dans un pilote industriel à l’intérieur duquel le matériau est disposé en nappes. La méthodologie du suivi consiste à faire varier la charge polluante en agissant sur le débit d’eau et le dopage de l’effluent, voire les deux. Les performances du procédé sont étudiées en mesurant régulièrement les paramètres classiques de pollution. Les caractéristiques hydrauliques du lit se déduisent de la distribution du temps de séjour, évaluée par traçage. La chromatographie en phase gazeuse permet de quantifier le transfert de l’oxygène. Le procédé fonctionne par cycles de 2 à 12 jours entrecoupés de lavages air-eau. La capacité maximale, mesurée en charge volumique appliquée, est d’environ 7 kgDCO/m³. J pour une durée de fonctionnement de 3-4 jours, satisfaisant le niveau de rejet e (norme française : MES 30 mg/l, DBO₃ 30 mg/l, DCO 90 mg/l). La modélisation des phénomènes de l’épuration révèle que : la cinétique d’élimination du substrat organique est d’ordre l ; la charge particulaire de l’eau épurée dépend à la fois du décrochage du biofilm, fonction de la vitesse de l’eau, et de la croissance des bactéries libres ; la durée du cycle est liée à l’accumulation de la biomasse fixée ; et que la diffusion du substrat organique contrôle l’épuration. De plus, cette modélisation a permis l’élaboration d’abaques de dimensionnement de lit immergé sur géotextile.

L’objectif de ce travail est d’exploiter les modifications que les divers supports numériques peuvent entraîner dans les constructions discursives dans plusieurs langues (nous comprenons ici le Roumain et le Français). Cette démarche prend appui donc sur les caractéristiques technologiques du support et encadre notre collecte selon la source : blog, forum de discussion, SMS, Facebook.La question est donc de savoir si ce(s) nouveau(x) mode(s) de communication change(nt) les règles (traditionnelles) de la communication (orale, écrite, du point de vue de la construction du discours).Pour évaluer si ces discours utilisant les nouvelles technologies sont différents des discours antérieurs, il faut pouvoir les comparer aux descriptions dont on dispose déjà, en l’occurrence (étant donné l’éventail choisi pour le corpus roumain comme pour le corpus français) ceux qui portent sur les dialogues et les conversations. Nous réaliserons cela à travers une analyse statistique de la fréquence des traits phénoménologiques rencontrés qui apportera des réponses complémentaires quant à la stabilité de ce nouveau registre discursif. Cela permettra d’encadrer la linéarité profonde de ce type de construction discursive et sa variation.Il s’ensuit une étude comparative des situations intra -culturelles (le contexte culturel inhérent qui peut sensiblement modifier le cadre conversationnel). Nous penchons pour une description des comportements interactionnels à l’intérieur de deux cultures afin de mieux les comparer. Aussi le déroulement prototypique de l’interaction dans une situation donnée autant que ses déclinaisons spécifiques selon une situation/ cadre/ locuteur particulier sont-ils pris en compteThis study aims to analyze the modifications that various digital supports can produce throughout several languages (we take into account Romanian and French). In doing that, it is influenced by the support’s technological features and therefor separates our corpus source accordingly: blog, chat, SMS, Facebook. The purpose is therefor finding if this (or those) new way (s) of communication change the traditional rules of exchange (spoken or written).In order to evaluate the differences between the digital discourse and the previous types, one has to compare the collected data to the prior types: dialogue and conversation. Statistical frequency analysis will complete our perspective as for this new discourse genre’s stability. This will allow shaping its general lines as well as its inner variation.The next step is a comparative study of various intercultural situations (the cultural context that can modify the speaking frame). We turn therefor towards a description of the interactive behavior within the two cultures. We shall take into account the interaction’s prototypical course in a given situation as well as its specificity according to the situation/ frame/ specific speaker
Scopul acestei lucrari este de a exploata modificarile pe care diversele platforme numerice le pot antrena in constructiile discursive de-alungul mai multor limbi (facem aici referire la Romana si Franceza). Acest demers se sprijina deci pe caracteristicile tehnologice ale suportului si incadreaza corpusul nostru in functie de sursa : blog, forum, SMS, Facebook. Problematica generala trateaza deci daca acest(e ) nou/-i mod (uri) de comunicare schimba regulile traditionale ale comunicarii (orale, scrise, din punct de vedere al constructiei discursului).Pentru a evalua daca aceste tipuri de discurs folosind noile tehnologii sunt diferite de discursurile anterioare, trebuie sa le comparam cu descrierile de care dispunem déjà, mai preciscele care se refera la dialoguri si conversatii (data fiind paleta de colecte aleasa atat pentru corpusul romanesc cat si pentru cel francez). Ne propunem sa realizam aceasta via o anlaiza statistica a frecventelor trasaturilor fenomenologice intalnite care vor aduce informatii complementare in ceea ce priveste stabilitatea acestui nou registru discursif.Vom putea astfel sa incadram atat linearitatea profunda a acestui tip de constructie discursiva cat si variatia sa inerenta.Pasul urmator este trasarea studiului comparativ a situatiilor culturale (contextul cultural inerent putand sa modifice in mod sensibi lcadrul conversational). Ne vom apleca astfel asupra unei descrieri a comportementelor interactive in interiorul celor doua culturi pentru a obtine o comparatie exhaustiva. Astfel derularea prototipica a interactiunii intr-o situatie data cat si declinarile sale specifice in functie de situatie/ cadru/ locutor specific, sunt elemente cheie in cadrul studiului nostru

Corporate support has become increasingly important to guarantee long-term viability in museums and cultural organizations. The topic is presented at different levels, from the simplest forms of donations to long-term agreements of partnerships between organisations and private firms. First, this paper will present a model framework of Italian cultural entities, describing the progressive transformation of their funding system from a preeminently public-dominated to a more mixed one, with particular reference to the competitive advantage and benefits arising from successful partnerships both for cultural and economic organisations. To investigate the phenomenon, a qualitative, explorative approach has been chosen, focusing on the case study of Fondazione Brescia Musei. In 2020, following up to its latest management model, the Foundation has launched Alleanza per la Cultura, a public-private non-competitive long-term agreement that has been signed by nearly 40 local corporate firms to boost the promotion and the conservation of the Foundation’s cultural heritage. Taking into consideration the internal characteristics of the organisations and the environment in which they act, this research will identify the efficacy of the project, arguing the positive long-term effects of similar partnership models in bringing a positive impact for all parties.

This work aims at investigating didatic practices, contents, resources and the use of didatic support materials in Natural Science classes described by teachers of 3rd and 4th grades and the interference of such teacher s education profile, of the Science content setting in the school curriculum and of school culture on this process. This empirical research has been accomplished with qualitative and analitic-descriptive methodology of such practices showed in interviews (with the aid of a program built and tested for this specific end) structured by 10 teachers of this level of schooling from municipal public schools in the city of São Paulo, all participants in a development program to the teaching of Natural Science. The research has also included the analysis of legal school documents relative to this curricular subject in the first years of Primary School. The results obtained allowed the description of the profile of the teachers who were interviewed: the great majority were graduated young women from low-income and low-education families, living in the same region as their students. Furthermore, by their practices it was possible to recognize the Science classes at the end of Primary School as a place of words , namely, the results permitted the identification of orality culture marks, according to M. Certeau s definition, in the school internal relationships (pedagogic coordinator, teachers, students), as well as the existence of a readers comunity in the school, in the perspective of Roger Chartier, specially related to oral texts about the national curricular patterns (Parâmetros Curriculares Nacionais) and their guidance concerning the Science teaching in the Primary School.
Este trabalho tem como objetivo investigar práticas didáticas, conteúdos, recursos e utilização de materiais de apoio didático nas aulas de Ciências Naturais descritos por professores de 3º e 4º ano do Ciclo I do Ensino Fundamental e as interferências, nesse processo, do perfil de formação desses professores, do lugar dos conteúdos de Ciências no currículo das escolas e da cultura escolar. Trata-se de pesquisa empírica, realizada com base em metodologia de natureza qualitativa, analítico-descritiva de tais práticas, expressas em entrevistas semi-estruturadas (com o auxílio de Roteiro, construído e testado para esse fim específico) por 10 professores dessa faixa da escolaridade, da rede pública municipal, de um município da Grande São Paulo, todos participantes de um Programa de Formação Continuada para o Ensino de Ciências. A pesquisa incluiu, ainda, a análise de documentos escolares e legais relativos a esse componente curricular nos anos iniciais da escolaridade fundamental. Os resultados obtidos permitiram, de um lado, caracterizar o perfil dos professores entrevistados: em sua maioria mulheres, jovens, com curso superior, oriundos de famílias pobres e com baixa escolarização e moradores da mesma região dos alunos e, de outro lado, reconhecer as aulas de Ciências nos anos finais do Ciclo I do Ensino Fundamental, por suas práticas, como um lugar de palavras , isto é, os resultados permitiram identificar as marcas da cultura da oralidade segundo as define M. Certeau presentes nas relações intra-escolares (coordenadora pedagógica-professores-alunos), bem como a existência, na escola, de uma comunidade de leitores na perspectiva de Roger Chartier em torno, especialmente, de textos orais sobre os Parâmetros Curriculares Nacionais e suas orientações em relação ao ensino das Ciências no Ciclo I do Ensino Fundamental.

Since the start of the Syrian war, Jordan has received many Syrian refugees with around 650,000 Syrians now residing in the country. As the state has received a lot of help from the international community, funding refugee camps and providing basic necessities, a lot of international humanitarian practitioners have come to Jordan to work alongside Jordanian and Middle Eastern practitioners. The situation therefore has brought practitioners from different academic, professional and geographical backgrounds together to work with people of a different cultural background than their own. Syrians represent a vast diversity in terms of ethnic, religious, linguistic and socio-economic backgrounds. Research have addressed that practitioners’ sensitivity to how cultural complexities may influence social problems can facilitate a better understanding of the client’s path to recovery. The purpose of our study was to increase the knowledge of mental health and psychosocial support practitioners’ understanding and experience of a culturally sensitive social work in Amman, Jordan and discuss how this affects their practice with Syrian refugees. Through qualitative interviews we found that the practitioners’ perception of Arab culture as one and the same makes culture a non-issue in terms of cultural diversity, and that this perception influence the practice with Syrian refugees in a number of ways.

This thesis seeks to apply some concepts and theories from predominantly post 1960 research in organisational behaviour to the study of the Arts Council as reflected through its policies, in the belief that few, if any, real attempts have thus far been made by academics to relate some of the profound difficulties of the public administration of the art to this branch of the sciences. The project is based on an examination of the assumption with which the Arts Council historically has justified both its general operations and its particular decisions. A close examination is made of past and recent statements of policy (I am assuming that administrators often make policy and advise in the making of policy and am treating decision making and policy making as synonymous for purposes of this thesis), the main aim being to identify the various ideological and structural determinants which bear upon decision making processes necessary for a subsequent evaluation of the various representative systems. These determinants vary from political pressures to aesthetic preconceptions, and overt to covert hierarchical power structures within the framework. Specific areas of concern have revolved around the problems of co-ordination, accountability and control of public subsidy to the arts and in particular, what model or models of organisational structure and decision-making processes might successfully reconcile traditional cultural criteria and alternative contemporary conceptions of artistic and cultural development and worth, including all current non-art criticism. In particular, the research has focused on what might be termed the Arts Council's 'secondary accountabilities-' (the word 'accountability' is usually only used when explaining its formal relationships with Government), in respect to artistic standards, artists and members of the general public. This is accountability imposed from 'below" the quango, a relatively undeveloped concept which this thesis examines in much greater detail. My points are illustrated by an examination of the policies of the arts agencies in Great Britain, New Zealand, Australia, America and Canada. Further comparisons are made between the Arts Council of Great Britain and Sports Council of this country in view of the proposals in New Zealand and Australia for a more integrated policy framework based on concepts of recreation and leisure which could result in a new Department of Recreation, Arts and Sport whose primary function would be to develop a national recreation policy to allow for coordinated development of all aspects of recreation, arts and sport. The examination is made largely from the point of view of organisation theory. For while I believe the cultural debate outlined in chapter one represents the crucial question for arts councils to resolve, organisation theory fortuitously illustrates these larger issues and also suggests some means of resolving the conflict between public accountability and responsibility to the development of the arts.

L'acquisition d'un caractere hydrophobe des supports de culture organiques au cours de leur dessiccation et ses consequences pour les cultures hors sol ont conduit a s'interesser aux caracteristiques et mecanismes mis en jeu dans l'acquisition d'un tel caractere. Dans cette optique, des tourbes d'origine botanique et de degre de decomposition differents, ainsi que des ecorces a divers stades de compostage ont ete selectionnees. L'etude prealable de leurs proprietes physico-chimiques et biochimiques ont permis d'etudier la variabilite de leurs proprietes physiques (en particulier leur capacite de rehumectation) en fonction de leur degre d'evolution. L'analyse des proprietes physiques au cours de deux cycles de dessiccation a montre que le degre de decomposition des tourbes va de pair avec un retrait croissant et irreversible. Le compostage des ecorces favorise une plus forte retention en eau et des capacites de rehumectation peu differentes de celles des ecorces fraiches. L'apport d'une nouvelle methodologie, basee sur le principe de remontee capillaire, a permis l'etude de la mouillabilite en fonction de l'etat hydrique du materiau. Le passage d'un caractere hydrophile a un caractere hydrophobe a ainsi pu etre evalue par la diminution des angles de contact au cours de la dessiccation, se traduisant par des surfaces, globalement monoplaires a l'etat hydrate, devenant progressivement apolaires a l'etat sec. En outre, les proprietes de surface dependent de leur etat d'evolution des materiaux. Une forte correlation entre les indices d'eau des materiaux (fonction du degre de degradation) et leur energie d'hydratation g a ainsi ete mise en evidence. Le role d'adjuvants mineraux (sable, argile) et de tensioactifs sur les proprietes physiques et la mouillabilite des materiaux a ensuite ete envisage. Si leur adjonction implique des variations positives ou negatives de la retention en eau volumique, elle contribue en revanche a une amelioration de la mouillabilite des substrats.

An institution of higher education was studied to determine whether its culture supported faculty scholarship. The site selected for the study was John Tyler Community College (JTCC) in Virginia chosen because it is fairly representative of other colleges in the Virginia Community College System (VCCS) and because its campuses were accessible to the researcher for the collection of study information. Ernest Boyer's broadened definition of scholarship was used to define scholarship in this study.;The research question--"Is the culture in a two-year public institution in Virginia supportive of scholarship as defined by Ernest Boyer"?---was addressed through case study methodology using qualitative and quantitative data collection gathered through interviews and document review. One-third of JTCC full-time faculty, five academic administrators, and VCCS's chancellor and director of professional development were interviewed using nineteen interview questions developed from Tierney's framework for assessing institutional culture. College document review related to these questions was done to triangulate information gathered from interviews.;The study's findings suggest that JTCC's culture does not support faculty scholarship strongly or consistently. In Tierney's elements of environment, mission, and socialization--most interview and document data show a consistent lack of support for scholarship: and in elements of information, leadership, and strategies there is limited, if any, document support for interview responses indicating that scholarship is supported at JTCC.;Future research on community college scholarship should investigate model institutions for scholarship engagement as well as definitions and standards of scholarship that are most fitting for two-year institutions. Further study is needed on the benefits of scholarship to community college missions and a body of literature on community college scholarship should be established.

This capstone project was part of a group project completed by five school and district administrators in Hillsborough County, Florida.
The project began because of our passion for teachers who are able to establish a culture of care in their classrooms that support students academically but transform their learning through experiences that enable them to be more highly engaged and productive students, regardless of ethnicity, socioeconomic status, perceived academic abilities, and backgrounds.
My focus in this group project looked at school climate, culture and student behavior in high needs schools. I asked, what steps can be taken by a school leader to improve school climate and culture in turnaround schools? What happens with student behavior as school climate and culture improve?
Selected literature was reviewed that concentrated on current issues with school discipline, multi-tiered approaches for support, and the role of school-based leadership in student success (mediated by the size of student enrollment). I applied what I learned to developing a collaborative working environment for teachers, implementing school uniforms, developing discipline procedures for managing student behavior, and looking for ways to encourage positive student behaviors. Key findings in my area of focus included development of a common understanding of discipline infractions and procedures, decrease in discipline referrals, increase in teacher satisfaction with discipline processes, and improved school grade.

La reconstruction des défauts du cartilage auriculaire nécessite une restauration appropriée par des sources cellulaires adéquates ainsi que la fourniture de supports appropriés pour les tissus. Ce travail visait à étudier différents échafaudages et biomatériaux pour l'ingénierie in vitro du cartilage auriculaire ainsi que la réparation in vivo du cartilage auriculaire chez des modèles de lapin. Nous avons d'abord montré que les périchondrocytes auriculaires sont les meilleurs candidats pour la régénération du cartilage auriculaire et que l'hypoxie n'est pas nécessaire à leur différenciation chondrogénique. Ces cellules ont formé avec succès des feuillets de cellules cartilagineuses que nous avons utilisés pour régénérer le tissu cartilagineux in vitro et pour combler et reconstruire les défauts du cartilage in vivo dans des modèles allogèniques de lapins. Nous avons ensuite testé des tissus dérivés de la cellulose en décellularisant un tissu de pomme. Une fois recolonisés avec des cellules, ces échafaudages ont surpassé les hydrogels d'alginate en augmentant la croissance et en régulant l'expression cartilagineuse dans différentes cellules de mammifères. Dans la dernière partie de la thèse, nous avons examiné des matrices sécrétées par les cellules et les avons utilisées comme revêtement pour différentes applications de culture cellulaire. Il est intéressant de noter que ces supports, une fois lyophilisés, ont favorisé la culture de cellules allo- et xénogéniques, augmenté la prolifération et stimulé la chondrogenèse. Nous avons également mis en évidence la préservation du phénotype lors de l’amplification des chondrocytes par passages successifs. Notre étude fournit de nouveaux outils et approches pour de multiples applications de culture cellulaireSuccessful reconstruction of auricular cartilage defects requires the appropriate restoration of the cartilaginous deformities by potential cell sources as well as providing suitable tissue supports. This work aimed to investigate different scaffolds and biomaterials for in vitro auricular cartilage engineering as well as in vivo auricular cartilage repair in rabbit models. We first showed that auricular perichondrocytes are the best candidates for auricular cartilage regeneration and hypoxia is not necessary for their chondrogenic differentiation. These cells successfully formed cartilaginous cell sheets which were used to regenerate cartilage tissue in vitro and to fill and reconstruct cartilage defects in vivo in allogenic rabbit models. Furthermore, we tested cellulose-derived tissue by decellularizing apple tissue and its use as a scaffold. Repopulated with cells, these scaffolds surpassed alginate hydrogels by enhancing colonization and upregulating the cartilaginous expression in different mammalian cells. In the final part of the thesis, we examined cell-secreted matrices and used them as a coating for different cell culture applications. Interestingly, these coatings promoted both allo- and xenogeneic cell culture, increased proliferation, and boosted chondrogenesis. We also highlighted phenotype preservation during chondrocytes expansion on these cell-secreted matrices. Our study provides novel tools and approaches for multiple cell culture applications

Section one of this thesis considers the impact of culture on the therapeutic relationship. A metasynthesis of client experiences of cross cultural therapy is presented, which generated three themes. The first recognises the assumption of difference in a cross-cultural therapeutic relationship and the assumption that lived experience is qualitatively different from what can be learned by a therapist. The second elaborates the processes by which clients bridge this assumed divide in order to get benefit from therapy, including divorcing problems from the context of their culture. The third explores the emergence of the known variables of therapeutic relationship in this context. Clinical implications and the importance of recognising individual context in therapy is discussed. Section two of this thesis reports an interpretative phenomenological analysis of the experiences of six Islamic scholars in supporting members of the community. Four themes were derived from this analysis 'Building a personal relationship with the ultimate authority'; 'Treating the whole person'; 'God's Medicine'; and 'Duty bound to help'. The implications of these themes for the process of supporting people of Muslim faith are considered and the development of closer relationships with other support providers discussed. The third section of this thesis critically reviews and reflects upon the above research and explores the use of qualitative research as a cultural outsider and the process of developing and carrying out cross cultural research including reflections on the specific process of Interpretative Phenomenological Analysis in this research context.

Blended learning, a combination of traditional face to face (F2f) instruction and computer-mediated communication (CMC), is a popular trend in many universities and corporate settings today. Most universities provide faculty members course management systems, such as Blackboard, Angel, and others as a way to organize and transmit course materials to students. In order to assess the pedagogical value of blended learning in a university-level first year composition (FYC) environment, it is necessary to view the environment through a critical lens and adequately train faculty in the need for and use of the features of the learning management software (LMS). The setting for this study is the Humanities and Communication Dept. of Florida Institute of Technology, a private university on Florida s east coast, consisting of around 6000 students. As I investigate the various pedagogical and theoretical issues of incorporating blended learning into the FYC environment, I critically examine the issues involved in implementing the program. I employ a blended research method to join the tracks of implementing a blended learning program and developing a culture of support together in the Humanities and Communication Department of Florida Tech. In examining program implementation, I use a combination of institutional critique, as advanced by Porter et al., together with an  ecological methodology, as outlined by Nardi and O Day. In examining the feasibility of creating a culture of support through the design of a faculty workshop, I mainly use Richard Selfe s methodology, although elements of the previous two methods operate as well. The results of my study provide a means by which faculty members can experience and realize the benefits, while avoiding the pitfalls, of implementing CMC into a f2f classroom and provide an action plan for other researchers to utilize in their own educational settings.Ph.D.

In order to remain competitive, many American businesses implement team-based work strategies. In many cases, however, teams fail in American organizations, which may be in part due to a conflict between American culture and the cooperative environment necessary for teams to function effectively. By comparing the literature regarding American culture, challenges faced by teams, and then corporate culture, it becomes evident that there are aspects of American culture that pose challenges but also that an appropriate corporate culture can mediate some areas of incompatibility. A collaborative corporate culture can induce cooperation among employees without asking employees to work in a manner that is counterintuitive, thus gaining the benefits of teams.

This research exposed some of the factors that affected organisational culture and group behaviour in Defence Equipment and Support (DE&S) from its inception in 2007 through to 2014, when it became a Bespoke Trading Entity. The factors that were examined included organisationally legitimised personal, social and geographic identity, and linguistic difference and group size. Metaphor was also used by group members to describe the relationship they had with their groups. Group size was another factor that affected group behaviour. Finally, the effects of socio-technical induction and socio-cultural integration were seen to be additional factors that allowed cultural drag to occur within DE&S. The research was an insider ethnographic study that used a qualitative, multi-factorial approach which encompassed 6 years of observations, 124 interviews, and included the analysis of appropriate DE&S policy documents. This thesis is considered to be unique because no research of this nature, or at this level, has been carried out in DE&S, the Defence Procurement Agency (DPA) and the Defence Logistics Organisation (DLO). In addition, no studies have investigated the organisational culture of DE&S, apart from Kirke (2007a unpublished), Kirke (2010), which was a published article that was informed by that pilot study. The factors that were identified combined to produce both an organisation that possessed multiple organisational cultures and one single ethos which was that of delivering equipment to troops and supporting the troops, described as ‘front-line-first’. There was also an organisational culture that was affected by both the socio-technical and socio-cultural interactions of its members and of unconscious behaviours. All of those factors acted together as a system of interactions, with different factors taking primacy depending on the organisational context, no single factor being consistently more important than any other. The ethos of “front-line-first” was embedded within the DE&S organisational culture as a value which may have been used as a metaphor for the primacy of the overarching organisational culture of supporting the front-line.

Autologous explant-derived cardiac stem cell (EDC) therapies are a promising therapy for ischemic cardiomyopathy, but straightforward clinical translation is limited by traditional culture conditions which are often supplemented with ill-defined and xenobiotic components such as fetal bovine serum. Therefore, we investigated the influence of a commercially sourced serum-free (SF) xenogen-free medium on human EDC yield, phenotype, in vitro measures of EDC performance, and post-infarct cardiac repair using an immunodeficient mouse model of acute myocardial infarction. Despite reduced production of several pro-cardiogenic cytokines, SF EDCs promoted similar vessel formation, circulating stem cell recruitment and cardiogenic differentiation as compared to standard cultures. Transplant of SF EDCs into immunodeficient mice 1 week after myocardial infarction boosted post-ischemic repair beyond that of standard EDCs by enhancing viable myocardium within the infarct. These findings demonstrate that serum-free culture methods provide a superior cardiac-derived cell product with ready clinical translatability.

Do you remember the first time you used an Automatic Teller Machine (ATM)? Or a pay-at-the-pump gas station? Or an airline e-ticket kiosk? How did you know what to do? Although you never received any formal instruction in how to interact with the self-service technology, you were likely able to accomplish your task (e.g., withdrawing or depositing money) as successfully as an experienced user. However, not so long ago, to accomplish that same task, you needed the direct mediation of a service professional who had been trained how to use the required complex technology. What has changed? In short, the technology is now able to compensate for the average consumer's lack of experience with the transactional system. The technology itself bridges the performance gap, allowing a novice to accomplish the same task as an experienced professional. This shift to a self-service paradigm is completely changing the dynamics of the consumer relationship with the capitalist enterprise, resulting in what is rapidly becoming the default consumer interface of the postmodern era. The recognition that the entire performance support apparatus now revolves around the end user/consumer rather than the employee represents a tectonic shift in the workforce training industry. What emerges is a homogenized consumer culture enabled by self-service technologies--a kiosk culture. No longer is the ability to interact with complex technology confined to a privileged workforce minority who has access to expensive and time-consuming training. The growth of the kiosk culture is being driven equally by business financial pressures, consumer demand for more efficient transactions, and the improved sophistication of compensatory technology that allows a novice to perform a task with the same competence as an expert. "The Kiosk Culture" examines all aspects of self-service technology and its ascendancy. Beyond the milieu of business, the kiosk culture is also infiltrating all corners of society, including medicine, athletics, and the arts, forcing us to re-examine our definitions of knowledge, skills, performance, and even humanity. The current ubiquity of self-service technology has already impacted our society and will continue to do so as we ride the rising tide of the kiosk culture.Ph.D.

Thesis (MBA) -- Stellenbosch University, 2011.The function of organisations is to deliver a product or a service, and thus the survival of an organisation is dependent on ensuring successful delivery in a financially viable manner. Project management was introduced to aid in this required successful delivery, placing emphasis on the cost, time and quality of the execution process of delivering the service or product. Project management does however not always deliver on successful service or product delivery, as can be deduced from the many projects that overrun budgets and timelines or under deliver on quality. The study of the impact of organisational culture stemmed from the movement in research to include the effect of the environment of a project on the effectiveness of the project management. Organisational culture has been noted to impact on many organisational elements, one of which is project management. In light of the current production and economic pressure experienced by Eskom’s power generating facilities, the effective and efficient management of projects plays a critical role in ensuring uninterrupted production and financial management. The success of the projects undertaken at Matla power station has a direct impact on the facility’s power generation capability and operational costs. This study found that the organisational culture of Matla supports effective project management at a level closer to the lower limits for the 12 cultural dimensions of a sample group of 29 national companies. Only two of the cultural dimensions rate below the national lowest rating. Considering the importance of projects for continued operational functioning, there is space for improvement in the level of support. A large plethora of factors impact on effective project management and the challenge for organisations lies in balancing the energy spent in addressing all the various factors. The difference between functional department needs and project needs must be balanced to ensure long-term goals are not given up for short-term production gains. Performance measurement should take cognisance of strategic long-term goals and must not be focused on purely short-term outcomes. The balance between production and projects is a continuous challenge. Project management plays an integral role in achieving the intense expansion required by Eskom over the next 15 to 20 years, the effective and efficient implementation of projects through effective project management must therefore be supported by the organisational culture.

This study investigates how the culture of an organization is related to the job satisfaction and turnover intentions of government accountants. I show that perceived organizational support serves as a mediator between organizational culture and both turnover intentions and job satisfaction. I evaluate how cultural effects have changed over time, and assess how the relations between the hypothesized associations differ between supervisory and staff accountants. I also look for differences in how accountants and primary care nurses may perceive organizational culture. I develop the constructs of interest, describe the proposed relationships, develop hypotheses, describe the sample frame, provide a detailed review of the methodology and describe the results. I conclude with a discussion of implications and limitations.

Organizational culture can be defined as a set of values and behavior that contribute to the unique social and psychological environment of an organization. It is the major contributing factor in determining the progress of an organization towards the desired objectives. The importance of organizational culture for successful Lean transformation has been emphasized prior research.
Lean implementation is based on continuous improvement, the achievement of which is based on problem solving practices. For sustained continuous improvement, problem solving must be done in a repeatable and disciplined way. However, not many organizations follow a structured approach towards problem solving. Some preliminary research indicates that organizational culture appears to be an important factor that influences the nature of problem solving practices used in an organization.
This research, therefore, is focused towards establishing whether a relationship exists between these two aspects, namely, organizational culture and problem solving practices in relation to an organization’s success with Lean transformation. A comprehensive survey was developed to evaluate these two aspects. The survey was then administered to employees at different organizations, designations, various sectors and geographical regions. The survey results were analyzed to evaluate if an organization’s culture influences the problem solving practices used.

La production par trichoderma harzianum de la 6-pentyl--pyrone (6-pp) qui possede un arome fort de coco a ete etudiee et comparee en milieu liquide et en fermentation en milieu solide (fms). Le milieu liquide de la culture submergee a ete utilise pour impregner un support solide de bagasse de canne a sucre en fms. La concentration maximale de 6-pp produite par t. Harzianum en fms a ete de 0,9 g/l, soit 17 fois plus qu'en milieu liquide. L'influence de la source de carbone, d'azote et du rapport carbone sur azote (c/n) sur la production de 6-pp en fms a permis de definir un milieu compose de glucose et de glycine dont le rapport c/n est de 14. L'atmosphere gazeuse (teneurs en o#2 et/ou en co#2) a influence l'initiation de la conidiogenese de t. Harzianum et la production de 6-pp. La culture du champignon dans une atmosphere riche en co#2 a permis une meilleure production de 6-pp qu'une culture dans une atmosphere identique a celle de l'air ambiant. La sporulation de t. Harzianum a ete retardee dans cette atmosphere modifiee. La production de 6-pp peut donc etre reliee negativement a la sporulation. La limitation de la croissance de t. Harzianum est le facteur le plus important pour favoriser la production de 6-pp. Le controle du metabolisme du champignon a ete possible en jouant sur le taux d'aeration des cultures. La limitation de croissance imposee par l'utilisation d'un taux d'aeration variable au cours de la culture a permis la production de 6-pp a environ 1,2 g/l. L'extrapolation de la production de 6-pp en fms d'un facteur 100 x a ete realisee efficacement en utilisant une geometrie de reacteur similaire comme critere d'extrapolation et le maintien d'une atmosphere gazeuse a 3% de co#2 comme strategie de culture. Sur 5 kg de substrat humide, le rendement de la 6-pp par rapport au glucose a ete de 40 a 45 mg/g. La fms pourrait donc representer a l'echelle industrielle une technique interessante pour la production de composes d'aromes et en particulier de la 6-pp.
