Professionele sosialisering in 'n privaathospitaal : 'n verpleegkundige perspektief / Naomi Louise TaljaardTaljaard, Naomi Louise January 2013 (has links)
The aim of this study was to make recommendations for the facilitation of professional socialization of the newly qualified registered nurse (NQRN) through exploration and description of the NQRN„s experience of professional socialization at a specific private hospital and factors that may contribute to the resignation of bursary holders.
The rationale behind this study was that bursary holders resign before or just after completing their contractual binding. An explorative, descriptive and qualitative research design was used. The sample included al the NQRN who met the inclusive criteria. Data collection was done by the writing of narratives by eight (8) participant‟s and followed with a focus group discussion to confirm the data. The contents was analyzed independently by two coders and three (3) themes and four (4) sub themes where identified. The first theme describes the NQRNs‟ experience of professional socialization and includes the sub themes, organizational climate and accompaniment. The second theme describes the reasons for resignation, namely salary and further study or training. A third theme describes the participants‟ recommendations to management to prevent resignation. The themes were described with relevant research- and subject literature. Each theme was summarized in a conclusion that served as basis for recommendations regarding the facilitation of the NQRNs‟ professional socialization to the private hospital‟s management and training department, as well as recommendations for further research.
The study was concluded with the researcher‟s evaluation of the study, identification of limitations and the researcher‟s reflection on the study. / MCur, North-West University, Potchefstroom Campus, 2014

An exploration on young adults' experiences of childhood parental alienation syndrome / Orgelena Maryna BorstlapBorstlap, Orgelena Maryna January 2014 (has links)
For over 20 years, the phenomenon of parental alienation and its related characteristics has been described in literature. Various clinicians independently researched and described the pathological alignment of a child within the context of divorce. In the 1980’s Richard Gardner coined this “Parental alienation syndrome” (PAS). According to Gardner PAS is characterised by a child’s profound preoccupation with criticism against a parent. This criticism is overstated and ungrounded, and it is caused by both conscious and unconscious behaviour by the alienating parent, which influences the child negatively against the alienated parent.
In essence, PAS is the subjective contamination of the child’s understanding and beliefs about his/her environment. The alienating parent gives the impression that the targeted parent is unworthy, dangerous, unloving and deserving of the child’s rejection. This is done by a series of alienation strategies like bad-mouthing, blaming, limiting contact and belittling. The alienated child, as a result responds with unjustified expressions of hate and discontent towards the targeted parent.
The experience of divorce can be very challenging to children. Research about the relationship between divorce and child adjustment holds that a child’s exposure to inter parental conflict and the quality of the parent-child relationship are the two major predictors of children’s adjustment during divorce. Research suggests that the negative effects of PAS may include guilt, self-hatred, distortion of reality testing, and general emotional and psychological problems. The aim of this study was to provide an in-depth exploration and description of how PAS is experienced, and the possible effect it has on children from the perspective of young adults who was possible exposed to PAS as children. This was done by exploring their memories and their recalled experiences of their parents’ divorce and the possible effect on their current lives.
In this study a collective exploratory/descriptive case study design was used. Nine voluntary participants, between 18 and 28 years of age, were chosen for this study by means of purposeful sampling strategies. Data were collected through in-depth semi-structured interviews that were audio taped and transcribed verbatim. Transcribed data were analysed by means of thematic analysis from which themes and sub-themes were derived.
Two main themes with sub-themes were identified. It was found that some of the parental behaviour evident in PAS cases may fall under specific subtypes of psychological maltreatment and leave children feeling angry, worthless, flawed, unloved, unwanted, incompetent and sceptical about trusting other individuals.
It was found that parents who engage in alienation strategies are likely to discourage autonomous behaviour and lack nurturance and emotional responsiveness towards their children’s needs. As result children exposed to PAS learn parental love and acceptance is conditional and is based needs fulfilment of the alienating parent. These expectations are brought forward from the early relationship into adulthood and influences individual’s expectations, behaviour, and beliefs about relationships across the lifespan. The results indicate that the lack parental support, encouragement, and responsiveness may negatively influence the self-esteem, autonomy, competence, and relatedness of individuals exposed to PAS. They reported difficulties with trust, intimacy and social skills and depression as adults. / MA (Clinical Psychology), North-West University, Potchefstroom Campus, 2014

Pharmacokinetics and dosing rationale of Para-Aminosalicylic acid in children and the evaluation of the in vitro metabolism of Ethionamide, Terizidone and Para-aminosalicylic acidLiwa, Anthony Cuthbert 03 1900 (has links)
Thesis (MScMedSc)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: BACKGROUND: The emergence of mycobacterium tuberculosis resistance to first line
drugs has renewed interest in second-line anti-tuberculosis drugs. Generally, Paraaminosalicylic
acid (PAS) is less potent and frequently more toxic than the first line
drugs. Furthermore, the pharmacokinetics of PAS in children has not been well
characterized.
AIMS: The aims of the present study were (1) to determine the pharmacokinetics of
PAS in pediatric patients, (2) to describe the discrepancy between children and adult
pharmacokinetics and the appropriate dosing regimen of PAS and (3) to investigate the
potential of the second-line anti-tuberculosis drugs PAS, terizidone and ethionamide
(often used as first-line drug in children) to inhibit the catalytic activities of CYP450 1A2
and 2C9.
PATIENTS: Twenty two patients with drug resistant tuberculosis were included in the
study. Ten patients were children with mean age of 4.2 years (range: 1 to 12 years).
Twelve patients were adults with mean age of 31.3 years (range: 18 to 53). 4 children
(40%) and 4 adults (33.3%) were HIV positive and were on ART.
METHODS: Children received 75 mg/kg twice daily on the first visit and after two weeks
they received 150 mg/kg once. Adults received a standard 4 g twice daily. Blood
samples were taken at different time points after the dose. In the additional study, the
inhibitory effects of PAS, ethionamide and terizidone on phenacetin O-deethylation, a
marker substrate of CYP1A2 and diclofenac 4’-hydroxylation, a marker substrate of
CYP2C9, were studied using human liver microsomes.
RESULTS: For the 75 mg/kg dose, the mean AUC was 233.3 =g•h/ml and the mean CL
was 10.4 l/h/kg. The mean of the observed Cmax of the drug was 45.4 =g/ml and the
mean Tmax was 4.8 hrs. For the 150 mg/kg dose, the mean AUC of PAS was 277.9
=g•h/ml and the mean CL was 47.1 l/h/kg. The mean of the observed Cmax of the drug
was 56.5 =g/ml and the mean Tmax was 4.8 hrs. On the first visit the mean AUC was 368
=g•h/ml and the mean CL was 13.2 l/h/kg. The mean of the observed Cmax of PAS was
51.3 =g/ml and the mean Tmax was 5.2 hrs. On the second visit the mean AUC was 230 =g•h/ml and the mean CL was 23.9 l/h/kg. The mean of the observed Cmax of PAS was
37.6 =g/ml and the mean Tmax was 5.2 hrs. The comparisons between pharmacokinetics
profile of PAS and patients characteristics e.g. age, indicated no statistically significant
differences between children (both treatment regimens) and adult patients as well as
HIV positive and negative patients. In the in vitro study, all drugs demonstrated no
inhibition potency towards the investigated CYP450 enzymes.
CONCLUSIONS:The dose of 75 mg/kg twice daily in children appears to be appropriate
to achieve serum concentration above the PAS minimum inhibitory concentration of
approximately 1 =g/ml. PAS, ethionamide and terizidone are unlikely to affect the
metabolism of concomitantly administered medications that are metabolized by either
CYP450 1A2 and/or 2C9 isoenzymes. / AFRIKAANSE OPSOMMING: AGTERGROND: Die opkoming van eersteliniemiddel-weerstandige mycobacterium
tuberculosis het opnuut belangstelling in tweedelinie-antituberkulosemiddels
aangewakker. Oor die algemeen is para-aminosalisielsuur (PAS) minder kragtig en
dikwels ook meer toksies. Verder is die farmakokinetika van PAS in kinders nog nie
goed vasgestel nie.
DOELSTELLINGS: Die doelstellings van hierdie studie was (1) om die farmakokinetika
van PAS in pediatriese pasiënte vas te stel, (2) om die diskrepansie tussen kinder- en
volwasse-farmakokinetika, sowel as die toepaslike doseringskedule, van PAS te beskryf
en (3) om die potensiaal van die tweedeline-antituberkulosemiddels PAS, terisidoon en
etioonamied (gereeld gebruik as eerste linie middels in kinders) te ondersoek wat betref
hul vermoë om die katalitiese werking van CYP450 1A2 en 2C9 te inhibeer.
PASIËNTE: Twee-en-twintig pasiënte met middelweerstandige tuberkulose is in hierdie
studie ingesluit. Tien pasiënte was kinders met ‘n gemiddelde ouderdom van 4.2 jaar
(reeks: 1 tot 12 jaar). Twaalf pasiënte was volwassenes met ‘n gemiddelde ouderdom
van 31.3 jaar (reeks: 18 tot 53 jaar). 4 kinders (40%) en 4 volwassenes (33.3%) was
MIV positief en was op TRM’s.
METODES: Kinders het 75 mg/kg twee maal daaliks gedurende die eerste besoek
ontvang en 150 mg/kg een maal ná twee weke ontvang. Volwassenes het ‘n
standaarddosis van 4 g twee maal daagliks ontvang. Bloedmonsters is op verskillende
tye ná die dosering geneem. In die addisionele studie is in die inhiberende effekte van
PAS, etioonamied en terisidoon op fenasetien-O-deëtilering, ‘n merkersubstraat van
CYP1A2 en diklofenak-4’-hidroksilasie, ‘n merkersubstraat van CYP2C9, ondersoek
deur gebruik te maak van menslike lewermikrosome.
RESULTATE: Vir die 75 mg/kg dosis was die gemiddelde area-onder-die-kurwe (AOK)
233.3 =g•h/ml en die gemiddelde middelopruiming (CL) 10.4 l/h/kg. Die gemiddelde
geobserveerde Cmaks van die middel was 45.4 =g/ml en die gemiddelde Tmaks was 4.8 h.
Vir die 150 mg/kg dosering was die gemiddelde AOK van PAS 277.9 =g•h/ml en die
gemiddelde CL 47.1 l/h/kg. Die gemiddelde geobserveerde Cmaks van die middel was 56.5 =g/ml en die gemiddelde Tmaks was 4.8 h. Gedurende die eerste besoek was die
AOK 368 =g•h/ml en die gemiddelde CL was 13.2 l/h/kg. Die gemiddelde
geobserveerde Cmaks van PAS was 51.3 =g/ml en die gemiddelde Tmaks was 5.2 h.
Gedurende die tweede besoek was die gemiddelde AOK 230 =g•h/ml en die
gemiddelde CL 23.9 l/h/kg. Die gemiddelde geobserveerde Cmaks van PAS was 37.6
=g/ml en die gemiddelde Tmaks was 5.2 h. Die vergelyking van PAS-farmakokinetika en
eienskappe van die pasiënte het geen statisties beduidende verskille in die gemiddelde
AOK tussen kinders (op albei doserings) en volwassenes getoon nie. Met die in vitrostudie
het geen van die middels inhibisie-werking teenoor die CYP450-ensieme wat
ondersoek is, getoon nie.
GEVOLGTREKKINGS: Die gevolgtrekking kan gemaak word dat die dosering van 75
mg/kg twee maal daagliks voldoende is om serumkonsentrasies wat bo PAS se
minimum inhiberende konsentrasie van 1 =g/ml te bereik. Dit is onwaarskynlik dat PAS,
etioonamied en terisidoon die metabolisme van gelyktydig-toegediende medikasies, wat
op hul beurt deur die CYP240-isoënsieme 1A2 en/of 2C9 gemetaboliseer word, sal
affekteer. / Division of Pharmacology, Stellenbosch

Développement d'outils de conception de Machines polyphasées à aimants utilisant l'Approche multimachine.Scuiller, Franck 13 December 2006 (has links) (PDF)
Cette thèse a pour objet le développement d'outils de conception de machines polyphasées à pôles lisses alimentées par onduleur de tension à modulation de largeur d'impulsion. Basée sur la décomposition multimachine de la machine polyphasée en une somme de machines fictives magnétiquement découplées et mécaniquement couplées, l'approche adoptée consiste à étudier le problème de l'adaptation convertisseur-machine en reportant les objectifs sur les machines fictives. Une représentation matricielle du bobinage polyphasé, le développement d'un modèle de calcul analytique du champ et l'introduction de la Transformée de Fourier Discrète permettent d'associer aux machines fictives un bobinage et une couche d'aimants. Les objectifs et contraintes liés à la réduction des courants arasites et à l'amélioration de la qualité du couple peuvent alors être formulés directement sur des grandeurs fictives, ce qui permet de déduire des démarches de conception optimale.

Intersubjectivité : modulation et ajustement. Cas des marqueurs discursifs "hein", "quoi", "n'est-ce pas" en français et "darô", "yo", "ne", "yone" en japonais / Intersubjectivity : modulation and adjustment. case of the discourse markers "hein", "quoi", "n'est-ce pas" in French and "darô", "yo", "ne", "yone" in JapaneseNoda, Hiroko 29 June 2011 (has links)
Cette recherche vise à rendre compte du fonctionnement et des conditions d’emploi de quelques marqueurs discursifs, en relation avec la problématique de l’intersubjectivité. Elle s’inscrit dans le cadre théorique développé par A. Culioli « la Théorie des Opérations Prédicatives et Énonciatives ». Ce travail est consacré d’abord aux descriptions des emplois de hein, quoi et n'est-ce pas en français du point de vue distributionnel, sémantique, pragmatique et prosodique. L’analyse se fonde sur un corpus oral constitué de séquences tirées de film et d’émissions de télévision. L’étude porte également sur les descriptions des emplois de darô, yo, ne et yone en japonais qui sont des marqueurs comparables à hein ; elle se termine par une analyse comparative entre hein et les marqueurs japonais étudiés dans le but de montrer dans quelle mesure leur enjeux énonciatifs se recouvrent. Il s’avère que ces deux ensembles de marqueurs jouent un rôle crucial dans l’organisation des rapports intersubjectifs entre l’énonciateur et le coénonciateur / This research aims to account for the functions and the conditions of the usage of the discourse markers in connection to the problem of intersubjectivity. It falls within the theoretical framework developed by A. Culioli “Theory of Enunciative Operations”. This work is devoted primarily to the descriptions of the usage of hein, quoi and n’est-ce pas in French with the distributional, semantic, pragmatic and prosodic point of view. The analysis is based on a corpus consisting of the clips from film and television. The study is also concerned with the descriptions of darô, yo, ne and yone in Japanese which are comparable with the marker hein. It is followed by a comparative analysis between hein and these Japanese markers which shows how their enunciative issues intersect. It proves that all these markers play a very important part in the organization of the intersubjective relations between the enunciator and coenunciator

The Medicago truncatula sucrose transporter family : sugar transport from plant source leaves towards the arbuscular mycorrhizal fungus / Medicago truncatulaDoidy, Joan 23 May 2012 (has links)
Pas de résumé en français / In plants, long distance transport of sugars from photosynthetic source leaves to sink organs comprises different crucial steps depending on the species and organ types. Sucrose, the main carbohydrate for long distance transport is synthesized in the mesophyll and then loaded into the phloem. After long distance transport through the phloem vessels, sucrose is finally unloaded towards sink organs. Alternatively, sugar can also be transferred to non‐plant sinks and plant colonization by heterotrophic organisms increases the sink strength and creates an additional sugar demand for the host plant. These sugar fluxes are coordinated by transport systems. Main sugar transporters in plants comprise sucrose (SUTs) and monosaccharide (MSTs) transporters which constitute key components for carbon partitioning at the whole plant level and in interactions with fungi. Although complete SUTs and MSTs gene families have been identified from the reference Dicot Arabidopsis thaliana and Monocot rice (Oriza sativa), sugar transporter families of the leguminous plant Medicago truncatula, which represents a widely used model for studying plant-fungal interactions in arbuscular mycorrhiza (AM), have not yet been investigated.With the recent completion of the M. truncatula genome sequencing as well as the release of transcriptomic databases, monosaccharide and sucrose transporter families of M. truncatula were identified and now comprise 62 MtMSTs and 6 MtSUTs. I focused on the study of the newly identified MtSUTs at a full family scale; phylogenetic analyses showed that the 6 members of the MtSUT family distributed in all three Dicotyledonous SUT clades; they were named upon phylogenetic grouping into particular clades: MtSUT1-1, MtSUT1-2, MtSUT1-3, MtSUT2, MtSUT4-1 and MtSUT4-2. Functional analyses by yeast complementation and expression profiles obtained by quantitative RT-PCR revealed that MtSUT1-1 and MtSUT4-1 are H+/sucrose symporters and represent key members of the MtSUT family. Conservation of transport capacity between orthologous leguminous proteins, expression profiles and subcellular localization compared to previously characterized plant SUTs indicate that MtSUT1-1 is the main protein involved in phloem loading in source leaves whilst MtSUT4-1 mediates vacuolar sucrose export for remobilization of intracellular reserve.The AM symbiosis between plants and fungi from the phylum Glomeromycota is characterized by trophic exchanges between the two partners. The fungus supplies the autotrophic host with nutrients and thereby promotes plant growth. In return, the host plant provides photosynthate (sugars) to the heterotrophic symbiont. Here, sugar fluxes from plant source leaves towards colonized sink roots in the association between the model leguminous plant M. truncatula and the arbuscular mycorrhizal fungus (AMF) Glomus intraradices were investigated. Sugar transporter candidates from both the plant and fungal partners presenting differential expression profiles using available transcriptomic tools were pinpointed. Gene expression profiles of MtSUTs and sugar quantification analyses upon high and low phosphorus nutrient supply and inoculation by the AMF suggest a mycorrhiza-driven stronger sink in AM roots with a fine-tuning regulation of MtSUT gene expression. Conserved regulation patterns were observed for orthologous SUTs in response to colonization by glomeromycotan fungi.In parallel, a non-targeted strategy consisting in the development of a M. truncatula - G. intraradices expression library suitable for yeast functional complementation and screening of symbiotic marker genes, similar to the approach that led to the identification of the first glomeromycotan hexose transporter (GpMST1), has been developed in this study.

Humanoid manipulation and locomotion with real-time footstep optimization / Manipulation et locomotion en robotique humanoïde avec optimisation temps réel des pasDang, Duong Ngoc 30 October 2012 (has links)
Cette thèse porte sur la réalisation des tâches avec la locomotion sur des robots humanoïdes. Grâce à leurs nombreux degrés de liberté, ces robots possèdent un très haut niveau de redondance. D’autre part, les humanoïdes sont sous-actionnés dans le sens où la position et l’orientation ne sont pas directement contrôlées par un moteur. Ces deux aspects, le plus souvent étudiés séparément dans la littérature, sont envisagés ici dans un même cadre. En outre, la génération d’un mouvement complexe impliquant à la fois des tâches de manipulation et de locomotion, étudiée habituellement sous l’angle de la planification de mouvement, est abordée ici dans sa composante réactivité temps réel. En divisant le processus d’optimisation en deux étapes, un contrôleur basé sur la notion de pile de tâches permet l’adaptation temps réel des empreintes de pas planifiées dans la première étape. Un module de perception est également conçu pour créer une boucle fermée de perception-décision-action. Cette architecture combinant planification et réactivité est validée sur le robot HRP-2. Deux classes d’expériences sont menées. Dans un cas, le robot doit saisir un objet éloigné, posé sur une table ou sur le sol. Dans l’autre, le robot doit franchir un obstacle. Dans les deux cas, les condition d’exécution sont mises à jour en temps réel pour faire face à la dynamique de l’environnement : changement de position de l’objet à saisir ou de l’obstacle à franchir. / This thesis focuses on realization of tasks with locomotion on humanoid robots. Thanks to their numerous degrees of freedom, humanoid robots possess a very high level of redundancy. On the other hand, humanoids are underactuated in the sense that the position and orientation of the base are not directly controlled by any motor. These two aspects, usually studied separately in manipulation and locomotion research, are unified in a same framework in this thesis and are resolved as one unique problem. Moreover, the generation of a complex movement involving both tasks and footsteps is also improved becomes reactive. By dividing the optimization process into appropriate stages and by feeding directly the intermediate result to a task-based controller, footsteps can be calculated and adapted in real-time to deal with changes in the environment. A perception module is also developed to build a closed perception-decision-action loop. This architecture combining motion planning and reactivity validated on the HRP-2 robot. Two classes of experiments are carried out. In one case the robot has to grasp an object far away at different height level. In the other, the robot has to step over an object on the floor. In both cases, the execution conditions are updated in real-time to deal with the dynamics of the environment: changes in position of the target to be caught or of the obstacle to be stepped over.

Marketingové oživení Cool tour linky / Marketing Revival of 'Cool tour linka'Majerová, Jolana January 2010 (has links)
The theme of this master's thesis is "Marketing Revival of 'Cool tour linka'". 'Cool tour linka' is a joint project of Prague's leading exhibition institutions and transport company. Introductory part presents the project with the aim to preserve it "for next generations" too. 'Cool tour linka' was terminated due to economical reasons. Therefore the thesis leads to formation of a new project, that would work under even less favourable conditions. Conclusions from the chapters that analyse the previous 'Cool tour linka' (analysis of the visitors' attendance, application of marketing tools, SWOT analysis) are used in the new project. Both the original and the newly proposed 'Cool tour linka' emphasize the element of cooperation of the organisations operating in the field of culture and the importance of unusual presentation of arts collections to the public.
