Spaces of New Labour Youth policy

Jacobs, Jeremy John January 2011 (has links)
This thesis examines the issue of policy change by focussing on time and space as the conditions of possibility for change. Drawing on post-structuralist theory, it interrogates existing theories of policy change with special attention paid to how these theories construct time and space. This engagement with policy theory, time and space leads to the introduction of a new theoretical logic which is termed the logic of demarcation. The logic of demarcation is then deployed along with other concepts, rooted in the post-Marxist political theory of Ernesto Laclau and Chantal Mouffe, such as political, social and fantasmatic logics, to investigate changes in New Labour youth policy from 1998 to 2008. The thesis focuses on the related but separable policy areas of Anti-social Behaviour and Every Child Matters and aims to explain change and/or resistance to change with respect to these policies as well as their relationship to each other. The aim is to examine the how the demarcations and exclusions that constitute these policy areas change over time. This is achieved by examining a mixture of textual data and drawing on data gained from primary interviews with key actors.

Identification des protéines FBP1 et FBP2 comme partenaires des protéines de liaison aux éléments riches en adénine et uridine (ARE) TIA-1 et TIAR

Rothé, Françoise 27 January 2006 (has links)
Dans les cellules eucaryotes, l’expression d’un gène peut être régulée à de nombreux niveaux. Les études réalisées sur le contrôle de l’expression génique se sont généralement intéressées aux mécanismes de contrôle transcriptionnel. Cependant de nombreux exemples mettent de plus en plus en évidence l’importance des mécanismes post-transcriptionnels dans cette régulation. Les contrôles post-transcriptionnels de l’expression génique reposent essentiellement sur des interactions spécifiques entre les régions 5’ et 3’ non traduites de l’ARNm et des protéines agissant en trans qui contrôlent spécifiquement la maturation des ARNs messagers (ARNms), leur localisation cytoplasmique, leur stabilité et/ou leur traduction. Les éléments riches en adénine et en uridine (ARE), localisés dans la région 3’ non traduite de nombreux ARNms, font partie des séquences régulatrices les plus étudiées. Elles sont notamment présentes dans les ARNms codant pour des cytokines et des proto-oncogènes. Les protéines de liaison à l’ARN jouent donc un rôle central dans la régulation de l’expression des gènes. Les protéines TIA-1 et TIAR appartiennent à la famille des protéines qui fixent l’ARN et qui contiennent des domaines RRM (RNA Recognition Motif). Elles sont impliquées dans des mécanismes permettant la régulation de l’expression génique tels que l’épissage alternatif et la traduction. En particulier, elles participent à l’arrêt général de la traduction qui accompagne un stress environnemental en séquestrant les ARNms poly(A)+ non traduits dans des foci cytoplasmiques appelés granules de stress (SGs). Elles sont également impliquées dans la répression traductionnelle d’ARNms spécifiques en liant les ARE présents dans les extrémités 3’ non traduites de certains ARNms, et notamment des ARNs messagers codant pour le TNF-α et la cyclooxygénase-2 (Cox-2). L’invalidation des gènes tia-1 et tiar chez la souris conduit à une létalité embryonnaire élevée suggérant que ces protéines jouent également un rôle important au cours de l’embryogenèse. Afin de comprendre les mécanismes par lesquels les protéines TIA-1 et TIAR remplissent leurs différentes fonctions, nous avons réalisé un criblage par la technique du double hybride en levure afin d'identifier des partenaires d’interaction de ces deux protéines. Les protéines TIA-1 et TIAR interagissent avec les protéines FBPs (Fuse Binding Proteins). Celles-ci participent notamment à la maturation et à la dégradation des ARNs. Nous avons montré que les protéines FBPs co-localisent parfaitement avec TIA-1 dans le noyau et migrent dans les granules de stress en réponse à un stress oxydatif. De plus, des expériences de retard de migration sur gel réalisées à partir d’extrait cytosolique de macrophages ont montré que les protéines FBPs sont présentes dans le même complexe liant l’ARE du TNF-α que TIA-1. Enfin, la surexpression du domaine de liaison à l’ARN KH3 de FBP2 en fusion à l’EGFP induit la séquestration spécifique des protéines TIA-1 et TIAR dans des foci cytoplasmiques, empêchant ainsi leur accumulation nucléaire. Nos résultats indiquent que les protéines TIA-1/R et FBPs pourraient être fonctionnellement impliquées dans des étapes communes du métabolisme de l’ARN dans le noyau et/ou le cytoplasme.

Measuring the underlying causes of long waiting times and the barriers to implementing recommendations to reduce waiting times, at a public sector primary health care facility in Cape Town

Caesar, Warren January 2017 (has links)
Magister Commercii (Information Management) - MCom(IM) / Long waiting times before receiving a health service, give rise to long queues and congested health facilities, both of which are unnecessary and avoidable. Since patients in part judge the quality of the service by the length of time they spent waiting for it, it is imperative to measure waiting times, and determine and mitigate the immediate and underlying causes of lengthy waits. The facility under investigation was known to have excessively long waiting times. Since the immediate causes of long waiting times were known, it was thus required to research and understand the underlying causes of long waiting times and consequently whether there were any barriers to implementing recommendations to reduce waiting times at this primary health care facility. Aim: The aim of the study was to determine the underlying causes of long waiting times and the barriers to implementing recommendations to reduce waiting times. Methods: A quantitative cross-sectional analytical study with a small qualitative component was undertaken. The qualitative study took a workshop format by piggy-backing onto feedback sessions held to present the results of the previously conducted waiting time survey to staff. Staff commentary at the workshops on possible underlying causes and barriers to recommendations to reduce them, were then used to develop a questionnaire for the quantitative portion of the study. The population and sample for the qualitative part of the study were all staff working at the facility who attended the feedback sessions. The cross-sectional descriptive quantitative study intended to uncover what underlying causes affected long waiting times, what recommendations could be explored to mitigate long waiting times and improve the patient experience, and if there were any barriers to these recommendations. The quantitative study population and sample were all staff who worked at the facility for more than six months and all patients who had utilised the services at the facility for three or more times. Data was collected using structured questionnaires, which were different for staff and patients. A detailed descriptive analysis was conducted. Results: The study found a number of potential underlying causes for each immediate cause of long waiting times at the facility. For early morning batching the underlying causes found were: 45% of patients were given early appointments which caused clients to arrive early; 100% of patients with appointments after 10H00 arrived before 10H00; and 43% of the patients stated that they arrived early because they feared being turned away.

Kaimo ir miesto kultūrų konflikto raiška profesinės mokyklos edukacinėje aplinkoje / Rural and urban cultures’ conflict expression in educational environment of vocational school

Mikalajūnienė, Elena 09 June 2006 (has links)
All over the world researches of youth life, value orientation, attitudes are important because at that time main social person psyche changes happen, which results are important for all his further life.To learn in vocational schools, which has specific features due to meaning of vocational training, the young people gather from different regions (rural and urban). According to research, in vocational school most of pupils are from rural, so their behaviour, habits, interests and intercourse with urban pupils have its peculiarity. Although at present lithuanian scientists are interested in youth life, culture, but in their works there is still not much attention to vocational schools. There schools’ system is located in both urban and rural territory, that is why children identification is important (sex, age, social group ). From here comes the problem of our research. While trying to signify not conflict interaction among urban and rural pupils educational environment of vocational school, it is necessary to identify possibilities, which have influence on these cultures’ expression, which is multicultural. The goal of research is to do the survey of urban and rural cultural conflict possibilities in vocational school and provide the dimensions in preventive program. For realizing the goal, the work had these tasks, it is based theoretically urban and rural cultures conflict main point and preconditions for multicultural interaction in vocational school, to do an empirical...

Vliv aminokyselinové variability na rezistenční fenotyp u ARE podrodiny ABC proteinů / The effect of aminoacid variability on the resistance phenotype in ARE subfamily of ABC proteins

Lenart, Jakub January 2012 (has links)
ARE subfamily proteins belonging to ABC transporters confers a different degree of resistance to macrolides, linkosamides and streptogramins antibiotics. Among the most clinically ARE subfamily proteins in staphylococci is Vga(A) protein lead to the award resistance to streptogtramins A. In 2006, discovered the new variant called the Vga(A)LC, which in addition to streptogramins A resistance also confers linkosamides. Vga(A) and Vga(A)LC differ in only 7 amino acids, yet confer different resistance phenotypes. In previous experiments it was found that the central role in determining substrate specificity play a 4 amino acid differences that accumulate in the section of 15 amino acids within the linker connecting the two ABC domains (positions 212, 219, 220 and 226). The combination of amino acids LGAG Vga(A) increases resistance to streptogramins A while present in combination SVTS Vga(A)LC increased resistance to linkosamides. Although in this subfamily includes a large number of resistance proteins, the mechanism of resistance has not yet been established with certainty. The aim was to create a new Vga(A) variants that contain specific combinations of amino acids for Vga(A) and Vga(A)LC protein at positions 212, 219, 220 and 226 and compared their ability to grant resistance to linkosamides. We also...

Vliv exprese genu lmr(C) na biosyntézu linkomycinu u Streptomyces lincolnesis: Rezistence nebo produkce? / Influence of expression of lmr(C) on the biosynthesis of lincomycin in Streptomyces lincolnensis: Resistance or production?

Veselá, Ludmila January 2015 (has links)
The genus Streptomyces produces more than a half of the known bioactive substances, ranking it among the most important bacterial taxons. Streptomyces lincolnensis ATCC 25466 encodes a biosynthetic gene cluster for lincomycin biosynthesis in its genome. Apart from the biosynthetic and regulatory genes, the cluster also contains three resistance genes, lmr(A), lmr(B) a lmr(C), which could protect of the host from the toxicity of a synthesized antibiotic. The Lmr(C) protein belongs to ARE proteins which generaly confer resistance to clinically important classes of antibiotics: macrolides, streptogramins, lincosamides and pleuromutilins. In addition to antibiotic producers, ARE proteins are also present in pathogenic microorganisms. However, the resistance mechanism conferred by these protins which belong to ABC transporters, even though they lack the transmembrane domain, have not been characterized yet. This makes the ARE proteins an interesting subject of the research. Using deletion mutants in resistance genes lmr(A), lmr(B) a lmr(C) we studied their effect on the lincomycin production and resistance to lincosamides, lincomycin and clindamycin with special focus on the function of the lmr(C). We have found that deletion of lmr(C) does not significantly influence lincomycin production and...

Rôle des miARN et des ARE-BP dans la mucoviscidose / Role of miRNA and ARE-BP in Cystic Fibrosis

Pommier, Alexandra 23 November 2018 (has links)
La mucoviscidose (CF, Cystic Fibrosis), maladie autosomique récessive la plus fréquente dans la population caucasienne, se manifeste par l’atteinte de plusieurs organes due à l’absence ou au dysfonctionnement du canal CFTR. Au niveau des poumons, la perte de l’activité du canal se traduit par une déshydration du mucus, des cycles d’infections et d’inflammation aboutissant à terme à la destruction du parenchyme pulmonaire. Les thérapeutiques proposées à l’heure actuelle, sont principalement symptomatiques et l’exploration de nouvelles pistes reste nécessaire. De récents travaux émanant de notre équipe ont révélé qu’une intervention au niveau de la stabilisation des transcrits pourrait être bénéfique pour améliorer la quantité de protéines nécessaires pour restaurer une activité suffisante du canal CFTR. Une autre piste qui pourrait être explorée serait de cibler, en plus de l’expression du gène CFTR, des régulateurs clés qui participent aux processus de réparation cellulaire ou à la réponse inflammatoire. Dans cet objectif, nous nous sommes focalisés sur des régulateurs clés comme les miARN et les ARE-BP (protéines de liaison à l’ARN) qui sont dérégulés dans les tissus CF et qui peuvent agir ensemble dans le contrôle de l’expression de nombreux gènes.Les travaux que nous avons réalisés nous ont permis d’une part, de montrer la dérégulation de miARN dans des échantillons CF ainsi que des isoformes de certains miARN. Deux miARN ont retenu notre attention, le miR-101 dont la distribution de ses séquences isomiR varient dans des cultures CF et le miR-181a-5p qui présente une dérégulation de son expression dans trois modèles ex-vivo CF que nous avons utilisés. Ces miARN ont la particularité de moduler l’expression de gènes clés dans les voies de signalisation PI3K-Akt/MAPK-Erk et Wnt. D’autre part, nos travaux ont révélé la dérégulation de la protéine ARE-BP TTP (Tristétraproline ou ZFP36) en contexte CF. Cette protéine est d’autant plus intéressante qu’elle est connue pour être un régulateur clé de l’inflammation. La suite de ce travail a donc été d’étudier sa régulation et son impact sur ses ARNm cibles. L’activité de cette ARE-BP a été principalement décrite pour être contrôlée par la voie p38-MAPK. Nous montrons l’implication de la voie p42/p44-MAPK (Erk1/2) dans la régulation de la phosphorylation de TTP dans des cultures bronchiques. La recherche des interactions entre TTP et ses cibles a également révélé que cette protéine agissait sur ses propres régulateurs ainsi que sur l’ARNm CFTR. Nous montrons ainsi pour la première fois que TTP se fixe au niveau de la région 3’UTR du transcrit CFTR et joue un rôle de stabilisateur sur ce transcrit.Identifier de nouveaux acteurs de la régulation du gène CFTR mais également des régulateurs centraux des processus altérés en contexte CF offre de nouvelles opportunités pour concevoir des outils ciblés pour combattre cette maladie. / Cystic fibrosis (CF), the most common life-shortening genetic disorder in Caucasians, affects many organs but chronic lung disease is the main cause of morbidity and mortality. This disease, characterized by CFTR gene alterations, results in ions transport dysfunctions that contribute to impair mucociliary clearance, favoring bacterial colonization and inflammation, and ultimately leading to lung destruction. Nowadays, therapeutic drugs have limited benefit, so development of new alternatives or complementary molecules remains essential. Recently, our team demonstrated that the intervention on CFTR mRNA stability leads to an increase in CFTR protein level and an improvement of the CFTR channel activity. An alternative way would be to target key actors such as miRNA and ARE-BP (RNA binding protein), deregulated in CF tissues, that display a pleiotropic activity and act together to control expression of several genes.Our findings led to the identification of dysregulated miRNA in CF samples and revealed multiple isoforms relative to miRNA of reference (i.e. isomiRs). We focused on two miRNA, miR-101, that displays a modification in isomiR distribution and miR-181a-5p that is highly deregulated, in three CF airways models. These miRNA modulate expression of key genes or related genes in PI3K-Akt/MAPK-Erk and Wnt signaling pathways.Our work also revealed the deregulation of an ARE-BP protein, TTP (Tristetraprolin, ZFP36), in CF context. This protein is a master regulator in inflammatory resolution. We next investigated the mechanism whereby this ARE-BP is regulated in bronchial cells and showed that TTP phosphorylation is regulated by MK2 through ERK activation. We also determined for the first time that TTP binds to the 3’UTR of CFTR mRNA where TTP binding stabilizes CFTR mRNA level.These data bring new insights into CF physiopathology and open new research opportunities in CF.
