Jämlik traumavård vid en traumaenhet : En retrospektiv studie om skillnader mellan traumapatienter beroende på tid på dygnet, kön och ålder / Equal trauma care at a trauma unit : A retrospective study on differences between trauma patients depending on time of the day, sex and age

Hernerud, Oskar, Qvarfordt, Malin January 2023 (has links)
Bakgrund: Trauma är en av de mest bidragande orsakerna till skada och död globalt. För att minska lidande och död hos patienter samt kostnader för samhället krävs en välfungerande traumavård. Tiden på dygnet, kön och ålder kan påverka utfallet för patienter som inkommer till sjukhus efter ett trauma. Eftersom forskningen inte är enig är detta ett område som ytterligare måste undersökas. Syftet med studien var att undersöka skillnader mellan traumapatienter vid en traumaenhet beroende på om patienten inkommer dagtid respektive jourtid, kön och ålder. Metod: Studien är en retrospektiv icke-experimentell tvärsnittsstudie där redan insamlade från en traumakoordinator vid ett sjukhus i norra sjukvårdsregionen analyserats. Studiepopulationen bestod av 115 patienter som blivit inskrivna som trauma nivå 1 eller 2 på akutmottagningen under år 2022. Data har analyserats med T-test och Chi-2 test för att undersöka eventuella skillnader och för att undersöka samband har Pearson’s korrelationstest använts. Signifikansgränsen sattes till P<0,05. Resultat: I denna studie kunde inga signifikanta skillnader identifieras mellan de trauman som inkom på dagtid och på jourtid gällande tid till vård eller allvarlighetsgrad av skadan. Kvinnor hade signifikant kortare tid mellan larm och ankomsttid till sjukhus. Det fanns ingen signifikant skillnad i allvarlighetsgrad beroende på tid på dygnet. Det fanns inte heller någon skillnad i allvarlighetsgrad mellan könen men det fanns ett positivt samband mellan hög ålder och allvarlighetsgrad. Slutsats: Vården vid det valda sjukhuset skiljer sig inte signifikant i traumaomhändertagande på dagtid och jourtid eller mellan könen vilket utifrån studerade variabler kan indikera en jämlik vård. Vidare studier skulle vara av intresse för att med andra variabler och infallsvinklar studera eventuella skillnader. Det finns också ett behov av jämförande analyser mellan sjukhus för att undersöka närmare hur jämlik vård som bedrivs i landet. Kunskapen är av vikt för anestesisjuksköterskan för att bedriva jämlik vård.

A review of solid waste management practices in Polokwane City

Maluleke, Prudence Hlamarisa 08 May 2014 (has links)
Bibliographical refernces appear at the end of each chapter / This study reviews solid waste management practices in Polokwane City. The study area covered some of the residential areas in Polokwane City; namely; Ivy Park, Fauna Park, Welgelegen, Westernburg and the City Centre. This article describes two main methods that were used to collect data; that is Qualitative and Quantitative method. Field survey was also made to validate data obtained from the participants that were interviewed during qualitative data process. After framing the problem, the objectives of Solid Waste Management Practices in Polokwane City were briefly outlined as follows: • Assess solid waste management practices in Polokwane City. • Make comparison on how households and the municipality take responsibility in storing, collecting, transporting, treating and disposing solid waste. • Investigate what problems the City encounters in managing solid waste. • Make relevant recommendations aimed at improving solid waste management practices within the City. The service management was administered by the municipality and private sector. From the five study residential areas, the Municipality manages waste in the City Centre while the private sector manages waste in the other residential areas. However, the City continues to play an administrative role over the contracted service provider. Statistical results were presented in figures and tables. The results showed the storage habits, frequency of collection, mode of transport and methods of disposal for solid waste in Polokwane City. The only method of disposal in the city was found to be landfilling. Activities that took place at the landfill site, such as reclaiming were outlined together with the economic values that these activities add to the City. The study also revealed that as population increases, the amount of solid waste generated also increased. / Environmental Sciences / M. Sc. (Environmental Management)

La signification expérientielle et les facteurs qui influencent la qualité de vie au travail des cadres gestionnaires infirmiers de premier niveau œuvrant en établissements de santé

Brousseau, Sylvain 08 1900 (has links)
Au cours des trois dernières décennies, le travail quotidien des cadres gestionnaires infirmiers de premier niveau (CGIPN) a subi de profondes transformations quant aux rôles qu’ils occupent et aux responsabilités qui leur incombent dans les divers établissements de santé. Ces CGIPN vivent et subissent de la pression au regard de leur charge de travail, faisant en sorte qu’ils perçoivent avoir peu de temps pour réaliser adéquatement leur travail en gestion, et que plusieurs infirmières de la relève qui souhaitent faire carrière en gestion se questionnent sur la possibilité d’œuvrer dans ce domaine de la pratique. Peu d’études portent sur l’état de la qualité de vie au travail (QVT) chez ces professionnels. Divisé en trois volets, le projet de recherche mixte séquentielle exploratoire a pour objectif général d’explorer la QVT chez les CGIPN et les facteurs qui l’influencent dans les divers établissements de santé québécois. Les objectifs spécifiques visent à : 1) décrire et comprendre ce que signifie la QVT auprès des 14 CGIPN œuvrant en Centre hospitalier affilié (CHA) à l’Université, 2) décrire et comprendre ce que signifie l’absence d’une QVT auprès des CGIPN en CHA, 3) développer et valider un nouvel instrument de mesure des facteurs favorables et défavorables pouvant influer sur la QVT à partir des données qualitatives auprès de CGIPN (n= 11) œuvrant en Centre de santé et des services sociaux et de CGIPN (n= 11) en Centre hospitalier universitaire, 4) identifier et mesurer les facteurs qui influencent la QVT des CGIPN (n= 291) travaillant dans divers établissements publics de santé et 5) déterminer si les caractéristiques sociodémographiques influencent le choix des facteurs de la QVT. Inspiré de la philosophie du Human caring de Watson comme perspective disciplinaire, le premier volet qualitatif fait appel à une méthode phénoménologique descriptive husserlienne. Pour ce faire, deux séries d’entretiens semi-dirigés à l’aide d’un guide d’entrevue visent à répondre aux deux premiers objectifs. Le second volet cible l’élaboration et la validation d’un instrument de mesure permettant de répondre au troisième objectif de la recherche et le dernier volet, de type quantitatif corrélationnel, s’applique à répondre aux deux derniers objectifs. Dans la première phase, l’analyse visuelle des données qualitatives (verbatim) permet l’émergence des résultats qualitatifs, soit de cinq eidos-thèmes favorables exprimés par les participants et décrits par ordre d’importance : 1) l’actualisation du leadership et des habiletés politiques pour l’amélioration de la qualité des soins infirmiers, 2) les éléments contextuels propices à l’humanisation organisationnelle, 3) le soutien organisationnel favorisant l’épanouissement socioprofessionnel et personnel, 4) l’organisation apprenante favorisant le développement des compétences en gestion des soins infirmiers et 5) l’accompagnement personnalisé répondant aux besoins spécifiques des novices en gestion des soins infirmiers. L’essence de la QVT pour les CGIPN se définit par l’émancipation socioprofessionnelle du cadre gestionnaire infirmier de premier niveau dans sa pratique clinico-administrative au sein d’une organisation humaniste. De plus, trois eidos-thèmes défavorables se dégagent des analyses qualitatives. Les résultats, décrits par ordre d’importance, sont : 1) la déshumanisation organisationnelle, 2) les conditions défavorables à la pratique en gestion des soins infirmiers et 3) l’accompagnement insuffisant des gestionnaires infirmiers novices. L’essence de l’absence d’une QVT pour les CGIPN se présente comme la dysharmonie au travail du cadre gestionnaire infirmier de premier niveau à l’intérieur d’une structure organisationnelle déshumanisante mettant en péril sa pratique clinico-administrative. Par la suite, une mise en relation des deux essences du phénomène a permis de faire émerger la signification universelle de l’expérience de la QVT et l’absence de celle-ci pour des CGIPN œuvrant en CHA comme étant : une dialectique en administration des services infirmiers dans laquelle se vit des pratiques humanisantes permettant l’atteinte d’un idéal de QVT, en coexistence avec des pratiques déshumanisantes conduisant à l’absence de QVT. Afin de respecter les postulats des méthodes quantitatives, les huit eidos-thèmes qui émergent de la première phase qualitative se transforment en facteurs favorables (FF) et défavorables (FD) à la QVT pour la réalisation des deuxième et troisième phases de la recherche. Dans la seconde phase, le construit théorique qui provient des huit eidos-thèmes et 23 thèmes permet de développer un nouvel instrument de mesure qui s’avère unique à cette population à l’étude. L’analyse psychométrique de l’instrument de mesure (questionnaire auto-administré en mode électronique) permet l’obtention d’un score global du coefficient alpha de Cronbach (α) de 0,93, ce qui est jugé excellent. Dans la troisième et dernière phase, les analyses statistiques des données (logiciel SPSS, version 22 pour Windows 7, 2013) issues de l’enquête quantitative provinciale en ligne (Web) mettent en évidence des résultats probants. Les résultats du questionnaire en ligne avec une échelle ordinale à cinq niveaux révèlent un score global du coefficient alpha de Cronbach à 0,95. De plus, les résultats quantitatifs suggèrent que les facteurs favorables (FF) à la QVT ont des scores moyens de 3,99 (FF1), 3,97 (FF2), 3,96 (FF3), 3,72 (FF4) et 3,53 (FF5) et les trois facteurs défavorables (FD) à la QVT ont des scores moyens de 3,91(FD1), 3,78 (FD2) et 3,56 (FD3). Ces facteurs correspondent aux eidos-thèmes favorables et défavorables de la QVT du volet qualitatif phénoménologique. Les résultats quantitatifs révèlent quelques relations significatives des caractéristiques sociodémographiques (âge et années d’expérience) sur le choix des facteurs qui influencent le plus fortement la QVT. En conclusion, le fait de pouvoir mieux décrire et comprendre la signification de la QVT ainsi que son absence et de pouvoir identifier les facteurs qui sont les plus susceptibles de l’influencer permet de formuler des recommandations pour les quatre domaines de la pratique infirmière. Des pistes d’avenues sont formulées pour maintenir la relève infirmière à des postes de CGIPN au sein des organisations de santé en lui assurant des moyens pour optimiser humainement sa QVT. / For the past three decades, first-line nurse managers’ daily work has undergone profound changes with respect to the roles they play and their compulsory responsibilities in various health care facilities. First-line nurse managers (FLNMs) are under pressure in regard to their workload; they find that they have little time to suitably accomplish their management work. Few studies address the quality of work life (QWL) of these health care professionals. The sequential and exploratory mixed methods research project is divided into three phases, and explores the QWL of FLNMs, as well as factors that influence FLNMs in various health care facilities in Quebec. Specific goals will : 1) describe and understandthe meaning of QWL according to 14 FLNMs working in the university-affiliated hospital (CHA), 2) describe and understandthe meaning of a lack of QWL among FLNMs in the CHA, 3) develop and validate a new measuring instrument of favourable and unfavourable factors that impact QWL of FLNMs’ within their health and social services network and university health centre (n= 11), 4) identify and measure factors influencing FLNMs’ QWL (n= 291), and 5) determine socio-demographic characteristics that may influence the choice of factors that affect QWL. Inspired from Watson’s Human caring philosophy as a disciplinary perspective, the first qualitative section uses a Husserlian descriptive phenomenological method. Two series of semi-structured interviews, using an interview guide, met the first two goals. The second section targets the development and validation of a measuring instrument that will allow us to meet the research goal. The last section refers to the correlational quantitative method, and it meets the last two goals. In phase one, a visual analysis of the qualitative data (verbatim) yields qualitative results that include five favourable eidos-themes expressed by participants, and are described in order of importance, namely : 1) an update to leadership and policy-making skills to improve health care quality, 2) contextual factors that promote organizational humanization, 3) organizational support to foster personal and socio-professional satisfaction, 4) a learning organization committed to skills development in health care management, and 5) personalized training to meet the specific needs of health care management beginners. The essence of FLNMs’ QWL is defined as the first-line nurse manager’s socio-professional emancipation in his or her clinical-administrative practices within a humanist organization. Three unfavourable eidos-themes emerge from the qualitative analyses. Here are the described results in order of importance : 1) organizational dehumanization, 2) unfavourable conditions in nursing management, and 3) insufficient support for beginner health care managers. The lack of QWL for FLNMs is described as disharmony in the first-line nurse manager’s workplace within a dehumanized organizational structure that jeopardizes his or her clinical and administrative practices. Consequently, comparing these two fundamental aspects of the phenomenon revealed the universal meaning of QWL, and its absence among F-LNMs working in university-affiliated hospitals, as being a dialectic in nursing administration in which humanist practices that allow attainment of a QWL ideal coexist with dehumanizing practices that work against QWL. Inorder to respect the quantitative methods’ principles, the eight eidos-themes emerging from the first phase are changed into favourable factors (FF) or unfavourable factors (UF) for QWL, and are used to carry out the second and third research phases. In the second phase, the theoretical construct based on the eight eidos-themes and twenty-three themes identified by the new measuring tool is unique to the population under consideration. The instrument’s psychometric analysis—a self-administered online questionnaire—obtained an overall Cronbach alpha score (α) of 0.93. This is considered excellent. In the third and last phase, a statistical analyses (SPSS software, version 22 for Windows 7) (2013) of Quebec’s online quantitative survey highlight conclusive results. Results from the online questionnaire, with a five-level ordinal scale, show an overall Cronbach alpha score of 0.95. Quantitative results suggest that QWL favourable factors (FF) have average scores of 3.99 (FF1), 3.97 (FF2), 3.96 (FF3), 3.72 (FF4), and 3.53 (FF5). QWL unfavourable factors (UF) have average scores of 3.91 (UF1), 3.78 (UF2), and 3.56 (UF3). These factors are equivalent to QWL’s favourable and unfavourable eidos-themes found in the qualitative phenomenological section. The quantitative results show some significant connections between socio-demographic characteristics, such as age and years of experience, and the choice of factors that affect QWL In conclusion, a better describing and understanding the meaning of QWL or lack thereof, as well as identifying the most likely factors to influence QWL, enables us to provide recommendations in the fourth areas of nursing practice. Approaches are proposed to maintain the next generation of FLNM job positions in health care organizations, while ensuring resources to suitably maximize FLNMs’ QWL.

Untersuchung von Dünnschichtsystemen mittels Elektronenstrahl-Mikroanalyse

Gorfu, Paulos 10 April 1992 (has links)
Die Arbeit beschäftigt sich mit der Erweiterung der für dicke Proben schon mit Erfolg eingesetzten Werkstoffanalytischen Methode Elektronenstrahl-Mikroanalyse (ESMA) mittels Peak/Untergrund-Verhältnissen auf die Analyse von dünnen Schichten (unter 1 μm) zur qualitative und quantitativen Elementanalyse sowie zur Ermittlung von Schichtdicken. Weiterhin wird auf der Basis von einer ESMA-Methode für zwei dünne Schichten auf einem Substrat wird ein Modell zur Ermittlung des Phasenwachstumskoeffizienten für eine intermetallische Phase die sich bei der Diffusion zwischen einer dünnen Schicht und einem Substrat bildet, mittels ESMA-Messungen bei gleichzeitiger Erwärmung der Probe dargestellt. / The paper deals with the application of the materials analysis method EPMA by peak-to-background ratios, which is currently being used for the analysis of thick samples successfully, to thin layers (less than 1 μm) for the quantitative element analysis as well as for thickness prediction. In addition a model has been established on the Basis of an EPMA method for two films on a substrate for deriving the phase growth coefficient of an inter-metallic phase which grows during the diffusion between a thin layer and a substrate from EPMA measurements while simultaneously heating the sample.

Arabismos en el español cotidiano : Un estudio diacrónico de frecuencias / Arabisms in colloquial Spanish : A diachronic frequency study

Lindqvist, Ingemar January 2021 (has links)
La larga presencia histórica de arabehablantes en la península ibérica tuvo como resultado la inclusión de préstamos léxicos, a menudo llamados arabismos, en el español. El objetivo de esta investigación ha sido comparar el uso de estos arabismos en el español cotidiano moderno con el del siglo XVI. Con este fin, se presenta una enumeración ordenada de los arabismos más frecuentes en el español moderno y se la compara con una lista correspondiente del español del siglo XVI. Las listas están basadas en dos corpus que maneja la Real Academia Española. Se realzan las semejanzas y diferencias entre las  dos listas y se discuten las posibles explicaciones de cambios en popularidad para los arabismos respectivos. Además, se presentan cálculos del porcentaje total de arabismos en el español de hoy y el del siglo XVI. Para este cálculo han sido usadas novelas de las dos épocas. Las novelas escogidas están todas arraigadas el las dos Castillas; por consiguiente, la comparación del porcentaje se limitará al español castellano. El estudio añade información cuantitativa que hasta ahora parece faltar respecto al conocimiento existente de arabismos en el español. El resultado de la investigación indica que la frecuencia de arabismos en la lengua cotidiana ha disminuido solo marginalmente desde el siglo XVI, mientras que el número de arabismos distintos en el uso corriente del español ha sufrido una reducción más pronunciada y el número de raíces hispanoárabes utilizadas ha decrecido aún más. Aproximadamente la mitad de los arabismos más frecuentes en el siglo XVI todavía mantienen esta posición; para la mayoría de los arabismos que han experimentado un aumento o reducción evidente en popularidad de uso existen explicaciones plausibles en forma de cambios en la sociedad. / The long-lasting historical presence of Arabic-speaking groups on the Iberian Peninsula resulted in various lexical loans, often referred to as arabisms, in Spanish. The objective of this investigation has been to compare the use of these arabisms in modern colloquial Spanish with that of the 16th century. For this purpose an ordered list of the most frequent arabisms found in modern Spanish is presented and compared with a similar list of arabisms found in texts from the 16th century. The lists are based on two corpus managed by the Royal Spanish Academy. Similarities and differences between the two lists are highlighted and possible explanations for the change in popularity of the respective arabisms are discussed. In addition, calculations of the total percentage of arabisms in current and 16th century Spanish are presented. Novels from the respective periods are used as a basis for these calculations. All the chosen novels are rooted in Castile; consequently, the percentage comparison is limited to Castilian Spanish. The study adds quantitative information that currently seems to be lacking to the existing knowledge of arabisms in Spanish. The result of the investigation indicates that the frequency of arabisms in colloquial language has diminished marginally since the 16th century, whereas the number of distinct arabisms in everyday usage of Spanish has suffered a more pronounced reduction and the number of hispanoarabic roots used has decreased even more. Approximately half of the most frequent arabisms in the 16th century still maintain this position; for a majority of the arabisms that have experienced an evident increase or decrease in popularity there exist plausible explanations in the form of changes in society.
