Bakgrunn: I helsesektorener det mange pleiere som arbeider ufrivillig deltid, noe som gjør at de ikke får forutsigbar inntekt og arbeidstid. En bemanningsenhet kan være et virkemiddel for å redusere omfanget av ufrvillig deltid. Hensikt: Studiens hensikt er å få kunnskap om hvilke faktorer som er viktige for at en bemanningsenhet skal kunne være en god og varig arbeidsplass for pleiereog samtidig gi tjenester av god kvalitet. Metode: Utvalget bestod av 14 pleiere som hadde arbeidet i en bemanningsenhet i syv til atten måneder. Datainnsamlingen ble hovedsakelig foretatt gjennom tre fokusgruppeintervjuer, og datamaterialet ble analysert ved metoden kvalitativ innholdsanalyse. Resultat: Tre kategorier ble identifisert og beskrevet: Organisering og kultur, Helsefremmende arbeidsplasser og Medarbeidernes kvalifikasjoner. Konklusjon: Studien viser at full fast stilling er en grunnleggende forutsetning for å rekruttere ansatte til bemanningsenheter. For å beholde de ansatte, er det viktig med systematisk og strukturert opplæring og vedlikehold og utvikling av kompetanse. Tydelig ledelse som skaper helsefremmende arbeidsplasser ved å legge til rette for mestring, anerkjennelse og tilhørighet er viktig for å beholde pleierne, og for at de skal gi tjenester av god kvalitet. De ansattes mestringsressurser og personlige egenskaper ser ut til å ha en betydning / Background: In healthcare manyc aregivers work part-time involuntarily, resulting in unpredictable income and work schedule. A staffing unit could providean efficient tool for reducingthe scope of involuntary work. Purpose: This study aimed to determine the important factors in supporting a good staffing unit and full-time work for caregivers while simultaneously providing quality services. Method: We recruited 14 caregivers,who had worked ina staffing unit for 7-18 months, to participate inthree focus-group interviews. We reviewed all data using qualitative content analysis. Result: We identified and describedthree categories: organization and culture, health promoting work places, and the qualifications of the employees. Conclusion: Our results show that a full-timeposition is a basic requirement for recruitment to staffing units. Retaining employees requires systematic and structured training as well as skill development and maintenance. Management should promote a healthy workplace by facilitating coping skills and recognizing achievement, ambition, and affiliation. Such promotion ensures careg ivers’ ability to provide quality care. The employees’ coping resources and personal skills appear to be significant. / <p>ISBN 978-91-86739-94-2</p>

Hensikt: Hensiktenmed studien var å undersøke forutsetningene for å være faglig leder for anestesisykepleiere i dagens norske helseforetak. Metode: Studien ble gjennomført med en kombinert metodikk: 1) Spørreundersøkelse med et skjema som forfatteren selv utviklet til alle førstelinjeledere for anestesisykepleiere i norske helseforetak,totalt77, med 80,5 % svarfrekvens. Datable analysert med kvantitative metoder.2) Halvstrukturerte individuelle intervju med syv ledere, strategisk utvalgt, både kvinner og menn, i alle landets fire regionale helseforetak, som det ble gjort en kvalitativ innholdsanalyse av. Resultat: I denne studien fant man at mange andre presserende oppgaver for lederne gjør at faglig ledelse ofte blir nedprioritertog delegert til andre, som fagutviklingssykepleierne. Lederne har et betydelig fokus på helsefremmende ledelse. Lederrollen er belastende, til tider slik at helsen påvirkes. Det er liten interesse for og nærmest ingen konkurranse om lederjobben. Av lederne er forholdsvis mange menn. Konklusjon: På grunn av de endrede rammebetingelsene,som følge av blant annet enhetlig ledelse og helseforetak,har lederrollen endret seg. Den har gått fra å stort sett være faglig leder til stadig mer personalledelse og administrative oppgaver. Lederne har i høy grad tilpasset seg de nye kravene, ogfungerer på mange måter som hybridlederemedettydelig fokus på helsefremmende ledelse.Anestesisykepleiefaget ivaretas gjerne av fagutviklingssykepleierne. Lederjobben oppleves som belastende og ikke særlig attraktiv for anestesisykepleiere / Aim: This study aimed to investigate the conditions being a professional leader of nurse anesthetists in Norwegian public hospitals today. Method: Thestudy used a combination of quantitative and qualitative methods, including a survey questionnaire constructed by the author and distributed to all first-line managers of nurse anesthetists in 77 Norwegian public hospitals, with a response rate of 80.5 %. The questionnaires were analyzed by quantitative methods. The author also conducted semi-structured individual interviews with seven strategically chosen leaders, both women and men, at hospitals in Norway’s four health regions. The interviews were analyzed using qualitative content analysis. Result: The results showed that leaders give less priority to professional leadership, largely due to many other urgent tasks, and frequently delegate this part of their leadership role to others (e.g., nurse anesthetists working with professional development). In leadership roles, nurse anesthetists focus on health promotion. They describe their managerial role as burdensome, at times even affecting their health. There is not much interest in and hardly any competition for managemen tpositions. Among the leaders, there is a relative dominance of men. Conclusion: Due to altered framework conditions, such as unitary management and health enterprises, the managerial role has changed, moving in responsibility from something more like a traditional foreman to becoming a first-line manager, who increasingly deals with personnel management and administration. Leaders have mostly adapted to the new demands.In many ways, they functionas hybrid leaders whofocus on health promoting leadership.Nurse anesthetistsperceive the management position as burdensome and not particularly attractive / <p>ISBN 978-91-86739-38-6</p>

Mångkulturell hälso- och sjukvård har ökat i Sverige på senare år på grund av krig i Syrien, och oro i andra länder i bland annat Mellanöstern och Afghanistan. Det har medfört mänskliga tragedier och stora flyktingströmmar. Sverige har tagit emot en stor andel av flyktingströmmen. Detta ställer nya krav på distriktssköterskan som i ett tidigt skede möter flyktingarna. Syftet med studien var att beskriva distriktssköterskans erfarenheter av hälsofrämjande och förebyggande arbete med nyanlända flyktingar ur ett vårdcentralsperspektiv. Metod: En kvalitativ intervjustudie med sju distriktssköterskor från olika vårdcentraler inom en västsvensk region. Materialet analyserades med en kvalitativ innehållsanalys. Resultat: Det framkom åtta subteman och fyra teman i analysen. Huvudteman var: Egenvårdens betydelse för att främja hälsan, Förebyggande arbete ur ett vårdcentralsperspektiv, Att kommunicera via tredje part samt Samordning mellan parter. Slutsats: Distriktssköterskornas hälsofrämjande och förebyggande arbete var betydelsefullt för de nyanlända flyktingarna eftersom distriktssköterskan var en av de yrkesprofessioner som de träffade i ett tidigt skede. Egenvårdsråd utmärkte det hälsofrämjande arbetet med nyanlända flyktingar men kunde vara svårt då många nyanlända flyktingar var vana från sina hemländer att alltid möta en läkare. Det utmärkande för det förebyggande arbetet var framförallt arbetet med vaccinationsuppföljning, som innebar en stor och krävande arbetsinsats för distriktssköterskorna. / Multicultural health and medical care has increased in Sweden during the last few years due to war in Syria and unrest in other countries among others in the Middle East and in Afghanistan. This has led to human tragedies and big streams of refugees. Sweden has received a large number of these refugees. This poses new demands on district nurses who at an early stage meet the refugees. The purpose of the study was to describe district nurses experience of health promoting and preventive care of newly arrived refugees from a perspective of the care centre. Method: A qualitative interview study with seven district nurses from different care centres within a region in West Sweden. The material was analysed with a qualitative analysis of content. Result: The analysis resulted in eight subthemes and four themes. Main themes were: The importance of self-care in order to promote health, Preventive work from a perspective of the care centre, To communicate through a third party and Co-ordination between parties. Conclusion: District nurses health promoting and preventive care was important for newly arrived refugees as the district nurse was one of the professionals they met at an early stage. Advice on self-care characterized the health promoting work with newly arrived refugees but could be difficult, as many refugees were used always to meet a doctor in their home countries. Characteristic for the preventive work was above all the follow-up of vaccinations, which required big and demanding efforts for district nurses.

Over the last few decades there has been a significant increase when it comes to mental ill health amongst Swedish schoolchildren. The school counselor has a crucial role both when it comes to detecting and to deal with these social problems. But according to recent studies the school counselors’ profession seems to lack a universal-based defined job description which has led to a decreased autonomy as well as legitimacy-related issues. This made us ask ourselves if the school counselors’ competence is used to its full potential. The overarching purpose of this study is to increase the understanding of how school social workers experience and perceive health-promoting work based on their professional role. The specific aims were to answer the following questions: How do school teachers experience health promotion at school? How does the school counselor perceive their professional role? Our method in order to collect our empirical data was to through semistructured interviews with six school counselors in Sweden. To help increase the understanding of our data we used profession-theory and also role-theory. The summarized findings are that the school counselors are a part of a group created to support the schoolchildren’s health. This group is heavily affected by the school organization’s resource assets and the school counselors’ perception is that there aren’t enough time nor enough professionals working with school-based health-promotion compared to the amount of students attending the school. We also found that the school counselors have different room, a different degree of autonomy, in order to influence the structure of the health-promoting work at school. Our conclusion is that this difference seems to depend on the principal as well as on the type of employment the school counselor has. The externally employed school counselor experienced much more autonomy compared to the internal employees. Furthermore, the school principal is proven to have a strong impact on the school counselors’ professional role and the school counselors have experienced legitimacy-related issues towards certain teachers due to their undefined job description.

Les plantes se développent et évoluent en interaction avec les organismes du sol. L'impact des vers de terre sur la croissance des plantes, généralement positif, a été attribué à des modifications physiques, chimiques ou biochimiques du sol, souvent sans démonstration rigoureuse. Dans ce travail, les techniques développées en sciences du végétal (culture in vitro, utilisation de mutants et transcriptomique) ont été utilisées afin de comprendre les mécanismes à l'origine de l'effet des vers de terre sur les plantes. Nos résultats apportent de nouvelles connaissances fondamentales: (1) la production de molécules-signal à l'intérieur des déjections de vers de terre a un impact significatif sur la croissance d'Oryza sativa et Lolium perenne. (2) Ces molécules agissent sur la voie de signalisation fortement liée à l'auxine, comme suggéré par l'effet significatif du ver de terre sur la croissance du double mutant d'A. thaliana aux1-7;axr4-2. (3) L'abondance de ces molécules-signal en présence de vers de terre pourrait être liée à la stimulation de certaines populations bactériennes capables de synthétiser de l'auxine. (4) Le ver de terre induit une accumulation de transcrits pour des gènes sous contrôle de l'acide jasmonique et de l'éthylène. Ces hormones sont notamment impliquées dans un mécanisme de résistance systémique induite (ISR), connu pour être induit par certaines rhizobactéries promotrices de la croissance des plantes. Enfin, (5) le piétin échaudage, maladie due à un champignon pathogène, déclenche chez le blé (Triticum aestivum) une réaction d'hypersensibilité et une modification de la signalisation hormonale, qui sont considérées comme des mécanismes de contrôle du métabolisme de la plante qui facilitent l'infection du pathogène. La sévérité de cette maladie est réduite en présence de vers de terre. La synthèse de ces résultats indique que les vers de terre, comme d'autres organismes du sol, modifient l'équilibre hormonal de la plante. L'homéostasie hormonale apparaît comme un élément incontournable pour prédire l'issue des interactions multiples que les plantes entretiennent avec les organismes du sol / Plants develop and evolve in interaction with soil organisms. The impact of earthworms, likely positive, has been attributed to modifications of physical, chemical or biochemical soil properties, without rigorous demonstration. In this work, techniques developed in plant science (in vitro culture, use of mutant plants and trancriptomic analysis) were used to understand the mechanism involved in the effect of earthworms on plants. Our results bring new fundamental knowledge: (1) production of signal-molecules within earthworm dejections has a positive impact on the growth of Oryza sativa and Lolium perenne. (2) These molecules act on auxin signaling, as suggested by the positive impact of the earthworm on the growth of A. thaliana double mutant aux1-7;axr4-2. (3) The abundance of these signal-molecules in presence of the earthworms could be related to the stimulation of bacterial communities able to produce auxin. (4) Earthworms induce an accumulation of gene transcripts known to be under control of jasmonic acid and ethylene. These two hormones are most notably involved in the defense mechanism called induced systemic resistance (ISR), known to be induced by plant growth promoting rhizobacteria. Finally, (5) Take-all disease, due to a pathogenic fungus, induced in wheat (Triticum aestivum) a hypersensitive response and a modification on hormone signaling, which are known as manipulations of plant metabolism in a way that facilitates pathogen infection. The severity of take-all disease was alleviated in the presence of earthworms. Synthesis of these results showed that earthworms, like other soil organisms, modify the hormone balance in the plant. Hormone homeostasis appeared to be an important element to predict the issue of the multiple interactions that plants established with soil organisms

Magister Scientiae - MSc (Biotechnology) / The yearly increase of global population will result in a greater demand for crop production, but with the climates changes and a lack of available agricultural land it will become increasingly more difficult to provide sufficient crops to feed everyone adequately. Application of the PGPE has proven over the past researches to be able enhance growth of plants via various growth promoting mechanisms. To identify suitable growth promoting bacteria candidate, E. plantagineum plant was used to isolate endophytes from the root after surface sterilization. The isolates bacteria were used to inoculate Brassica napus L seeds. The effects of isolate's ability to promote growth were evaluated based on the certain growth parameters after 42 days in the green house. Isolate CP5 produced highest results in all growth parameter. Isolates CP5 was selected as potential candidate as significant improvement was shown by this isolate. This isolate was tested for the ability to produce ACC deaminase, solubilize phosphate, synthesize IAA and siderophore production. Furthermore isolate CP5 growth promotion abilities was tested on Brassica napus L under antimony stress. / 2021-08-31

Potential vegetative and reproductive increases in yield, as well as the biological efficacy against Fusarium verticillioides and F. proliferatum causing ear and stem rot in maize crops of commercially-formulated micro-organism formulation T-Gro (Trichoderma harzianum isolate DB103 WP) combined with Spartacus (Beauveria bassiana isolate DB 105 WP), T-Gro combined with Armenius (Bacillus subtilis isolate DB 109 WP), T-Gro combined with Maximus (Bacillus subtilis isolate DB 108 WP), T-Gro combined with Shelter (Bacillus subtilis isolate DB 101), T-Gro combined with Bismarck (Microbacterium maritypicum isolate DB 107 WP), as well as individual treatments of T-Gro, Armenius, Bismarck, Maximus and Shelter, were investigated when applied to maize seed and soil under field conditions. All the micro-organism treatments were compared with Thiram 750WP (750g/kg thiram WP) and an untreated control. The micro-organism treatments showed an increase in vegetative as well as reproductive yields when compared to the reference product Thiram 750 WP and the untreated control. There were no observations of adverse effects on the germination of maize seed in all the treatments that were applied. The three isolates B. subtilis, T. harzianum, and M. maritypicum, showed a significant reduction in vascular tissue discolouration of the main and ear stems, indicating a potential to be used in the reduction and control of diseases caused by Fusarium spp. Results also showed poor to very good increases of stem and foliage biomass as well as cob yield per plant produced by the micro-organism treatments when compared to the untreated control. The highest cob yield per plant that differed significantly from the untreated control was produced by T-Gro and Shelter. No phytotoxicity of any kind was observed with the application of the micro-organism formulations and they could therefore be deemed suitable to be used for the treatment of maize seed. The micro-organism formulations containing fungal and bacterial biological control agents have the potential to be used in commercial maize production to increase vegetative and reproductive yields and reduce the severity of ear and stem rot in maize. / Agriculture Animal Health and Human Ecology / M.Sc.
