Nyckeln till värdeskapande nätverk - En kvalitativ studie om chefsarbete och nätverksrelationer

Examensarbetets titel: Nyckeln till värdeskapande nätverk - En kvalitativ studie om chefsarbete och nätverksrelationer Seminariedatum: 2018-01-12 Ämne/Kurs: FEKH49, Examensarbete i organisation på kandidatnivå, 15 högskolepoäng Författare: Ulf Gustavsson, Ebba Isacsson & Elin Nordahl Handledare: Stefan Sveningsson Nyckelord: Chefsarbete, chefsaktiviteter, nätverkande, relationer, värdeskapande, Syfte: Syftet med studien är att undersöka och nyansera vad en chefs nätverksrelationer innehåller som skapar värde i chefsarbetet. Metod: För att besvara studiens frågeställning har en kvalitativ fallstudie genomförts med semistrukturerade intervjuer. Studien har tagit en socialkonstruktionistiskt och tolkande utgångspunkt och bygger på en iterativ induktiv arbetsprocess. Teoretiska perspektiv: Studien utgår ifrån tidigare forskning inom området för chefsarbete. Första avsnittet ger en beskrivning om vad chefsarbete innebär för att sedan gå vidare in på chefsaktiviteten nätverkande. Empiri: Studiens empiri har samlats in genom intervjuer med tre chefer från olika företag och branscher. Resultat: Studien ger bidrag till området chefsarbete genom att identifiera vad en nätverksrelation kan innehålla för att bygga värdefulla nätverk. Nätverk bygger på relationer och det har identifierats att relationerna bör innehålla förtroende, tillgänglighet, ärlighet samt gemensam värdegrund för att möjliggöra att en chef får värde ut från sina nätverk. Genom resultatet ger studien verktyg till cheferna som de kan använda i sitt nätverkande

The relationship between radiation doses to coronary arteries and location of coronary stenosis requiring intervention in breast cancer survivors

Abstract Background To assess the relationship between radiation doses to the coronary arteries (CAs) and location of a coronary stenosis that required intervention after three-dimensional conformal radiotherapy (3DCRT) for breast cancer (BC). Methods The study population consisted of 182 women treated for BC in Sweden between 1992 and 2012. All women received 3DCRT and subsequently underwent coronary angiography due to a suspected coronary event. CA segments were delineated in the patient’s original planning-CT and radiation doses were recalculated based on the dose distribution of the original radiotherapy (RT) plan. The location of the CA stenosis that required intervention was identified from the Swedish Coronary Angiography and Angioplasty Registry (SCAAR). Logistic regression analysis was used to assess the relationship between CA radiation doses and risk of a later coronary intervention at this specific location. Results The odds ratio (OR) varied by radiation dose to the mid left anterior descending artery (LAD) (p = 0.005). Women receiving mean doses of 1–5 Gray (Gy) to the mid LAD had an adjusted OR of 0.90 (95% CI 0.47–1.74) for a later coronary intervention compared to women receiving mean doses of 0–1 Gy to the mid LAD. In women receiving mean doses of 5–20 Gy to the mid LAD, an adjusted OR of 1.24 (95% CI 0.52–2.95) was observed, which increased to an OR of 5.23 (95% CI 2.01–13.6) for mean doses over 20 Gy, when compared to women receiving mean doses of 0–1 Gy to the mid LAD. Conclusions In women receiving conventional 3DCRT for BC between 1992 and 2012, radiation doses to the LAD remained high and were associated with an increased requirement of coronary intervention in mid LAD. The results support that the LAD radiation dose should be considered in RT treatment planning and that the dose should be kept as low as possible. Minimising the dose to LAD is expected to diminish the risk of later radiation-induced stenosis
