The goal of this study was to explore the experiences of adolescents who were orphaned by HIV/AIDS related conditions, thereby improving the knowledge base and insight of social workers that will enable them to render more effective services. The objectives of this study was: -- To build a knowledge base of existing literature on the impact of HIV/AIDS related circumstances on orphaned adolescents. -- To conduct an empirical study of the experiences of adolescents on the following terrains, namely Belonging, Mastery, Independence and Generosity. -- To make recommendations about the experiences of adolescents orphaned by HIV/AIDS related conditions to be considered during formulation of intervention plans by social workers. This qualitative study endeavoured to answer the following research question: “What are the experiences of adolescents orphaned by HIV/AIDS related conditions in the Gert Sibande region of Mpumalanga?” The researcher aimed to document these experiences to improve the helping professions’ understanding of the phenomenon. This may lead to more successful intervention strategies for these adolescents. The study was feasible, as it was within the financial and practical means of the researcher. She had access to the target group and she had permission from the Department of Health and Social Services to conduct the study, using their resources, clients and data. Three themes emerged from data analysis, namely: -- THEME ONE: Sources of support, hurt and anger -- THEME TWO: My life changed after I became an orphan -- THEME THREE: Parents’ illness and death From the research findings, recommendations were made on a micro, macro and meso level. On a micro-level, this included improved foster parent screening, life skills camps, improved awareness campaigns and the establishment of support groups. On macro-level, the researcher is of the opinion that the strengthening of Home Based Care Groups, After-school centres and Children’s Homes should receive attention. / Dissertation (MA (Social Work))--University of Pretoria, 2007. / Social Work and Criminology / unrestricted

Läkemedel är förknippat med stora risker inom hälso- och sjukvården. Patienter inom intensivvården löper dessutom högre risk att utsättas för läkemedelsfel då de erhåller många fler läkemedel jämfört med patienter på vårdavdelningarna. Då läkemedelsrelaterade vårdavvikelser ökat på den studerade intensivvårdsavdelningen genomfördes ett förbättringsarbete för att öka patientsäkerheten inom läkemedelshanteringsprocessen. Det övergripande målet för förbättringsarbetet var att minimera risken för att patienter ska drabbas av en läkemedelsrelaterad vårdskada genom att utveckla arbetssätt som främjar en säker läkemedelshanteringsprocess för sjuksköterskorna på intensivvårdsavdelningen. Som SMART mål sattes att antal läkemedelsrelaterade vårdavvikelser per månad skulle minska med 60%. Studiens syfte var att förklara förhållanden som påverkar införandet av de förändrade arbetssätten. Förbättringsarbetet genomfördes med utgångspunkt i Nolans förbättringsmodell. Den vetenskapliga fallstudien hämtade sitt empiriska material från fokusgruppsintervjuer med sjuksköterskorna på intensivvårdsavdelningen. Studiematerialet analyserades med hjälp av en tematisk analysmodell. Förbättringsarbetets SMARTa mål nåddes inte. Faktorer som påverkade införandet av förändrade arbetssätt var bl.a. motivation och ökad medvetenhet hos medarbetarna samt kunskapsförmedling och förbättringsteamets tillgänglighet. Trots att förbättringsarbetets mål inte nåddes vittnar fokusgruppsintervjuerna om att vissa kulturförändringar skett och att läkemedelshanteringsprocessen underlättats något. Att underlätta det dagliga arbetet så att så mycket som möjligt går bra är bl.a. det som utmärker Säkerhet-II-perspektivet. / Medications are associated with great risks in healthcare. Patients in intensive care are also at higher risk of being exposed to medication errors as they receive many more medications compared with patients in the wards. As medication errors increased in the studied intensive care unit, a quality improvement project was carried out to increase patient safety in the medication management process. The main goal of the quality improvement project was to minimize the risk of patients suffering from an adverse drug event by developing routines that promote a safe medication management process for the nurses in the intensive care unit. The SMART goal was to reduce the number of medication errors per month by 60%. The purpose of the study was to explain conditions that influence the introduction of the changed routines. The quality improvement project was carried out on the basis of Nolan´s improvement model. For the scientific case study empirical material was collected through, focus group interviews with the nurses in the intensive care unit. The study material was analyzed using a thematic analysis model. The SMART goal of the quality improvement project was not achieved. Factors that influenced the introduction of changed routines were e.g. motivation and increased awareness among the nurses as well as knowledge transfer and the improvement team´s availability. Despite the fact that the goal of the quality improvement project was not achieved, the focus group interviews testify that certain cultural changes have taken place and that the medication management process has been facilitated somewhat. To facilitate the daily working processes so that as much as possible goes well is something that characterizes the Safety-II-perspective.

Syftet med arbetet har varit att undersöka hur digitalisering påverkar olika företag och därmed upplysa Fastighets AB L E Lundberg om deras befintliga hyresgäster får förändrade beteenden inom verksamheten som på sikt kan leda till förändrade lokalbehov. Detta för att informera Fastighets AB L E Lundberg om de behöver se över affärsmodellen med långa avtalstider som kan bli ohållbart i framtiden. Studiens resultat bygger på svar från intervjupersoner som representerar de olika företagen som hyr kommersiella lokaler av Fastighets AB L E Lundberg. Totalt intervjuades nio företag, varav ett företag intervjuades över elektroniskt källa. Intervjuerna gick ut på att intervjupersonerna fick svara på en enkät som innehöll frågor om ”digitalisering” då – och nutid samt ”fastighet” då – och nutid. Resultatet visar att alla företag är medvetna om begreppet digitalisering och har ändrat någon del av verksamheten åt det digitala hållet. En del företag, beroende på verksamhet, har påverkats mer internt medan andra företag har påverkats mer externt mot kund och omvärld. Enligt resultatet kommer digitalisering att påverka företag i allt större utsträckning i framtiden och ställa högre krav på fastighetsägarens affärsmodell med långa kontraktstider. / The purpose of the study has been to investigate how digitalization affects different companies and thus inform Fastighets AB L E Lundberg if their existing tenants get changed behaviors within the business which in the long term can lead to changed facillity needs. This is to inform Fastighets AB L E Lundberg if they need to revise the business model with long contractual periods that may become unsustainable in the future. The study's results are based on responses from interviewees who represent the various companies that rent commercial premises by Fastighets AB L E Lundberg. A total of nine companies were interviewed, of which a company was interviewed via electronic source. The interviews suggested that the interviewees answer a questionnaire that contained questions about "digitalization" then - and presently as well as "real estate" then - and presently. The result shows that all companies are aware of the concept of digitalization and have changed some part of the business in the digital way. Some companies, depending on their business, have been affected more internally while other companies have been affected more externally to customers and environment. According to the result digitalization will affect companies to an increasing extent in the future and impose higher demands on the property owner's business model with long contract times.

Bakgrund: År 2020 drabbades 22,200 patienter i svenska befolkningen av hjärtinfarkt. Patienters upplevelse efter insjuknandet är ofta oro, ångest och rädsla för att drabbas av ytterligare en hjärtinfarkt. Fysisk aktivitet är rekommendation efter en infarkt, dock uppfylls inte rekommendationen på grund av rädsla att aktiviteten ska utlösa ytterligare en infarkt. Även andra livsstilsförändringar har visat sig vara svårmotiverade. Syfte: Syftet med denna studie var att beskriva patienters upplevelser av livet efter en hjärtinfarkt. Metod: Studien är en litteraturöversikt baserad på 11 vetenskapliga artiklar. Resultat: Ur analysen framträdde två huvudteman: patienters upplevelser av den förändrade livsstilen efter en hjärtinfarkt och upplevelsen av första tiden i hemmet efter en hjärtinfarkt tillsammans med fyra underteman. Under första temat framkom följande underteman, den oförutsedda tröttheten och rädslor och ångest inför nya kost- och motionsvanor. Under tema två framkom följande: Vikten av socialt stöd från omgivningen efter hemkomst samt fysiska och psykiska upplevelser i vardagen. Konklusion: Patienternas liv efter en hjärtinfarkt påverkas både psykiskt och fysiskt. De är i stort behov av stöd av både vårdpersonal och personer i sin omgivning. / Background: In 2020, 22,200 people of the Swedish population suffered a heart attack. Patients' experience after falling ill is often worry, anxiety and fear of suffering another heart attack. Physical activity is recommended after a heart attack, however, the recommendation is not met because there is a fear that the activity will trigger another heart attack. Other lifestyle changes have also proven to be difficult to adapt. Aim: The aim was to describe patients' experiences of life after a heart attack. Method: The study is a literature review based on 11 scientific articles.  Findings: Two main themes emerged from the analysis: Patients' experiences of the changed lifestyle after a heart attack and the experience of the first time at home after a myocardial infarction, together with five sub-themes. Under the first theme, the following subthemes emerged: Uncertainty about one's new body's abilities, the unexpected fatigue and fears and anxiety facing new dietary and exercise habits. Under theme two, the following emerged: The importance of social support from the environment after returning home and physical and psychological experiences in everyday life. Conclusion: Patients' lives after a heart attack are affected both psychologically and physically and are in great need of support from healthcare staff and people around them.

A successful company today is focusing on minimizing costs, maximizing customer satisfaction, and increasing productivity. E-commerce is a tool to achieve the requirements that a company needs to reduce costs. Maximizing customer satisfaction and increasing productivity is a way to implement the requirements that are needed for a company to be successful today. E-commerce is being used on a daily basis in many different industries and the evolution of digitalization makes it possible for a company to increase customers as e-commerce makes the company more accessible. The duty of e-commerce is to make stronger bonds between companies, customers, and suppliers in the business cycle. Better communication, increased effectiveness, and opportunities for more jobs are benefits that e-commerce has contributed. The focus of this study is to gain an understanding of the possible changes that the implementation of e-commerce has brought to the retail industry in terms of work organization and digital competence. Other research areas that the study is focusing on include digitalization and value-added service. The main reason why this study is focusing on subjects like digitalization and value-added service is that digitalization is the core of building an e-commerce company. Many companies are using e-commerce as a complement to their business, and this is where the value-added service utility is being used.  The study shows that the implementation of e-commerce in a company affects the working procedure through opportunities for flexibility. From the interview we can come to the conclusion that it also creates opportunities for more effective sustainability work. We used Malmo Universities search engine to be able to find the sources we needed, and that includes peer-reviewed material. Course literatures were also used to improve the information on our bachelor thesis about e-commerce. E-commerce is frequently being studied from an economic perspective, and therefore we choose to limit our study to focus more on economic sustainability than ecological sustainability. This is the reason why we think that the future studies should focus on ecological sustainability. / Ett framgångsrikt företag fokuserar idag på att minimera kostnaderna, maximera kundnöjdheten och öka produktiviteten. E-handel är ett verktyg för att uppnå de krav som ett företag behöver för att minska kostnaderna. Att maximera kundnöjdheten och öka produktiviteten är ett sätt att genomföra de krav som krävs för att ett företag ska vara framgångsrikt idag. E-handel används dagligen i många olika branscher och utvecklingen av digitaliseringen gör det möjligt för ett företag att öka antalet kunder då e-handel gör företaget mer tillgängligt. E-handelns uppgift är att skapa starkare band mellan företag, kunder och leverantörer i konjunkturcykeln. Bättre kommunikation, ökad effektivitet och möjligheter till fler arbetstillfällen är fördelar som e-handeln har bidragit med. Fokus för denna studie är att få en förståelse för de eventuella förändringar som implementeringen av e-handel har inneburit för detaljhandeln när det gäller arbetsorganisation och digital kompetens. Andra forskningsområden som studien fokuserar på är digitalisering och mervärdestjänster. Den främsta anledningen till att denna studie fokuserar på ämnen som digitalisering och mervärdestjänster är att digitalisering är kärnan i uppbyggnaden av ett e-handelsföretag. Många företag använder e-handel som ett komplement till sin verksamhet, och det är här som nyttan av mervärdestjänst används.  Studien visar att implementeringen av e-handel i ett företag påverkar arbetsförfarandet genom möjligheter till flexibilitet. Utifrån intervjun kan vi dra slutsatsen att det även skapar möjligheter för ett effektivare hållbarhetsarbete. Vi använde oss av Malmö universitets sökmotor för att kunna hitta de källor vi behövde, och det inkluderar peer-reviewed material. Kurslitteratur användes också för att förbättra informationen i vår kandidatuppsats om e-handel. / <p>Genom zoom.</p>

L’imprévision est un thème à la frontière entre liberté contractuelle et justice contractuelle. Cependant, un nouveau regard peut être porté sur cette institution du droit des contrats grâce à la théorie des contrats relationnels développée par Ian R. Macneil ou encore à travers le contrat-coopération théorisé par Suzanne Lequette. Ces théories invitent à prendre en considération la valeur intrinsèque du lien contractuel et l’incomplétude du contrat. L’imprévision fait donc partie intégrante des contrats relationnels de par leur nature. La vocation première des contrats relationnels est de perdurer, obligeant les contractants à des normes de coopération et de flexibilité. Sous couvert de bonne foi, la relationnalité serait le fondement des changements de circonstances. Une étude comparative du régime des changements de circonstances apporte certaines précisions. Il semble exister deux approches des changements de circonstances, l’une restreinte aux modifications économiques et l’autre étendue, basée sur l’objectif ou le fondement contractuel. Une approche étendue de l’imprévision semble nécessaire dans les contrats relationnels. Enfin, les effets des changements de circonstances devraient donner priorité au maintien de la relation et à la norme de coopération en imposant une renégociation puis en permettant une adaptation judiciaire des termes de l’engagement. La résiliation, contraire à la nature des contrats relationnels, ne devrait intervenir qu’exceptionnellement. / Hardship is a topic at the border between contractual freedom and contractual justice. However, a new glance can be carried on this institution of contract law through the theory of relational contracts developed by Ian R. Macneil or the contrat-cooperation theorised by Suzanne Lequette. This theory invites to take into account the intrinsic value of the contractual link and the incompleteness of the contract. Imprévision thus forms integral part of the relational contracts from their nature. The primary purpose of the relational contrat is to continue, forcing the contractors to standards of cooperation and flexibility. According to good faith, the relationnality would be the foundation of changed of circumstances. A comparative study of the regime of changed of circumstances makes certain clarifications. There appear two approches of the changed of circumstances, one restricted based on economic modifications, and the second wide one, based on the purpose or foundation of the contract. Finally, the effects of the changed of circumstances should give priority to maintain the relation and the norm of cooperation by imposing renegotiation then by allowing judicial adaptation of the terms of the contract. Termination, contrary to the nature of relational contracts, should intervene only exceptionally.

The methodology to achieve this objective was conducted in two main lines, one aimed at mapping the spill changed under rock sound and other features aimed at it, it was used in both field and laboratory techniques. Field leakage was mapped covering up the roads of the study area, recording your GPS location and later in overlays on aerial photographs at scale 1: 25,000. The information obtained in the field as well as those resulting from photointerpretation registered in the overlays in the laboratory were scanned using the Spring 5.1 software and Corel Draw X5. As a final product was obtained Geological Geomorphological map of the Study Area in Plateau Palmas (PR) / Água Doce (SC). From this mapping it appears that the spill changed stratigraphically located between two strokes rock sound, so your exposure on the surface can be related to the uplift of the Plateau de Palmas (PR) / Água Doce (SC). This process has been inferred by Paisani et al. (2008a). It is also observed that outcrops of this type are found both beneath the surface 1200m 1300m III as above surface I of Paisani et al. (2008a). This demonstrates that their distribution beyond the limits of the Plateau de Palmas (PR) / Água Doce (SC), giving it a regional character. The distribution of this spill changed therefore shows that the geomorphology of the study area was strongly influenced by tectonic lineament of the Iguaçu River Paleozoic age. The analysis of the drainage network shows formation of anomalous curves and inversion of relief isolated paleo 2nd order in watershed regional Iguaçu / Uruguai. This probably should have originated from neotectonic. To characterize changes in the stroke field was processed macroscopic description of the materials and collected samples for laboratory examination in two sections, the SS1 and SS2. The laboratory techniques used were: grain size distribution analysis micromorphology, clay mineralogy by X-ray diffraction (XRD) and by total chemical X-ray fluorescence (XRF). From the results of such analysis it was inferred that the stroke changed under the bedrock plateau Palmas (PR) / Água Doce (SC) is part of a system of low sulphidation epithermal hydrothermal whose style hydrothermal alteration is pervasive and predominant stage of change that stroke is the propilítico. This would correspond to hydrothermally altered stroke distal halo of a larger hydrothermal system. SS2 section the mineral is more representative chlorite using this mineral as a geothermometer can be inferred that the spill changed that section was subjected to hydrothermal fluids with temperatures above 300 º C. Section SS1 mineral cristobalite is the most representative. From the presence of this mineral is inferred that the spill changed was subject to fluids lowest temperature that section SS2, as this mineral is stable in the temperature range between 100 º C and 150 º C, appearing in those deposits farther away from the source warm fluid. / Esta dissertação de mestrado apresenta o mapeamento e caracterização de derrame alterado sob rocha sã no Planalto de Palmas (PR)/Água Doce (SC). A metodologia de trabalho para atingir tal objetivo foi conduzida em duas linhas principais, uma visando mapear o derrame alterado sob rocha sã e outro visando caracteriza-lo, em ambas empregou-se técnicas de campo e laboratório. Em campo o derrame foi mapeado percorrendo-se as estradas da área de estudo, registrando sua localização em GPS e posteriormente em overlays sobre fotografias aéreas em escala 1: 25.000. As informações obtidas em campo bem como as resultantes da fotointerpretação registradas nos overlays em laboratório foram digitalizadas com os software Spring 5.1 e Corel Draw X5. Como produto final obteve-se o mapa Geológico Geomorfológico da Área de Estudo no Planalto de Palmas (PR)/Água Doce (SC). A partir desse mapeamento verifica-se que o derrame alterado estratigraficamente encontra-se entre dois derrames de rocha sã, de modo que sua exposição na superfície pode relacionar-se a soerguimento do Planalto de Palmas (PR)/Água Doce (SC). Esse processo já foi inferido por Paisani et al. (2008a). Observa-se também que afloramentos desse tipo são encontrados tanto abaixo de 1200m na superfície III como acima de 1300m, superfície I de Paisani et al. (2008a). Isso demonstra que sua distribuição extrapola os limites do Planalto de Palmas (PR)/Água Doce (SC), conferindo-lhe caráter regional. A distribuição desse derrame alterado, portanto mostra que a geomorfologia da área de estudo foi fortemente influenciada pelo lineamento tectônico do Rio Iguaçu de idade paleozoica. A análise da rede de drenagem mostra formação de curvas anômala e inversão do relevo que isolou paleocanais de 2ª ordem no divisor de águas regional Iguaçu/Uruguai. Isso provavelmente tenha se originado a partir de esforços neotectônicos. Para caracterização do derrame alterado em campo foi processada a descrição macroscópica dos materiais e coletadas amostras para análises laboratoriais em duas seções, a SS1 e a SS2. As técnicas de laboratório empregadas foram: granulometria; análise micromorfológica; mineralogia de argila por difração de raio-X (DRX) e química total por fluorescência de raio-X (FRX). A partir dos resultados de tais análise inferiu-se que o derrame alterado sob rocha sã no planalto de Palmas (PR)/Água Doce (SC) faz parte de um sistema hidrotermal epitermal de baixa sulfetação cujo estilo de alteração hidrotermal predominante é o pervasivo e o estágio de alteração desse derrame é o propilítico. Tal derrame alterado hidrotermalmente corresponderia ao halo distal de um sistema hidrotermal maior. Na seção SS2 o mineral mais representativo é a clorita, usando esse mineral como um geotermômetro pode-se inferir que o derrame alterado nessa seção esteve sujeito a fluidos hidrotermais com temperatura acima de 300º C. Na seção SS1 o mineral mais representativo é a cristobalita. A partir da presença deste mineral infere-se que o derrame alterado esteve sujeito a fluidos de mais baixa temperatura que na seção SS2, pois tal mineral é estável na faixa de temperatura entre 100º C e 150º C, aparecendo naqueles depósitos mais afastados da fonte de fluído quente.
