Förtroende i ansvarsfördelade organisationer : En kvalitativ fallstudie hur aktörer skapar och bibehåller förtroende
No full textTitel: En kvalitativ fallstudie hur aktörer skapar och bibehåller förtroende i organisationer med fördelat ansvar Nivå: Kandidatuppsats Författare: Jens Bergvik och Hanna Eriksson Handledare: Stig Sörling och Tomas Källquist Datum: 2015 – januari Syfte: Enligt tidigare forskning är förtroende grunden för många av organisationens resultat och basen i fungerade relationer och samarbeten. Sambandet mellan förtroende och den ansvarsfördelade organisationen är identifierad men saknar praktisk forskning, då en ansvarsfördelad organisation kräver samarbete beroende på att många har befogenhet till ansvar och beslutsmakt. Syftet med denna studie är därmed att ge en ökad förståelse för hur aktörer skapar och bibehåller förtroende samt att belysa förtroendets roll i ansvarsfördelade organisationer. Metod: Studien har utgått från ett hermeneutiskt perspektiv och fenomenet som studerats ses vara av socialkonstruktivistisk art. Med hjälp av deduktion har teori och empiri arbetats fram där grunden för studien har varit i form av en fallstudie som antar ett kvalitativt angreppssätt genom semistrukturerade intervjuer. Resultat & slutsats: Studien tyder på att förtroende är svårt att beskriva då det uppfattas som en abstrakt fenomen och därav avsaknaden av konkreta verktyg. De faktorer som istället anses ha inverkan på förtroendenivån är också de faktorer som används för att skapa och bibehålla förtroende, vilka är kompetens, kommunikation och förståelse. Förslag till fortsatt forskning: Förtroende har en betydande roll i samtliga organisationsstrukturer och denna studie är avgränsad till en ansvarsfördelad organisations struktur. Dessutom finns även infallsvinklar om hur och genom vem förtroende skapas. Uppsatsens bidrag: Studiens bidrag är hur aktörer skapar och bibehåller förtroende samt betydelsen av förtroende i ansvarsfördelade organisationer. Studien tyder på att uppfattningen om förtroende är ett fenomen som är svårt att beskriva eftersom det är abstrakt. Och visar på att vikten av förtroende i ansvarsfördelade organisationer för att samarbeten och delegering av ansvar ska fungera. De faktorer som studien bidrar med för att skapa förtroende är kompetens, kommunikation och förståelse. För att bibehålla förtroende är studiens bidrag att arbeta kontinuerligt med kompetens och kommunikation. Nyckelord: Decentralisation, distributed responsibility, organisational trust, trust, create trust, retain trustTitle: A qualitative case study research on how operators create and retain trust in organisations with distributed responsibility Level: Bachelor thesis Author: Jens Bergvik och Hanna Eriksson Supervisor: Stig Sörling och Tomas Källquist Date: 2015 – January Aim: According to earlier research trust is important to many of the organisations results and the base in relationship and collaboration. The connection between trust and organisations with distributed responsibility is identified but there is a lack of practical research. With distributed responsibility there will be a need of collaboration, when a lot of people have responsibilities and authority to make decision. The purpose of this report is to increase understanding about how operators create and retain trust and to highlight the role of trust in organisations with distributed responsibility. Method: The report adopts a hermeneutic perspective and the studied phenomenon assumes to be a social construction. A deductive approach have been used to collect theoretical and empirical information. The base for the report is a case study with a qualitative approach through semi-structured interviews. Result & Conclusions: The report implies that trust is difficult to describe because it is perceived as an abstract phenomenon and therefore there is an absence of concrete tools. Instead, the factors that is considered to influence trust is also the factors that is being used to create and retain trust, which is competence, communication and understanding. Suggestions for future research: Trust has an important role in organisations and this report is limited to a specific organisational structure. Another suggestion is to study the different operators’ role in the process of creating trust. Contribution of the thesis: The reports contribution is how operators create and retain trust and highlight the role of trust in organisations with distributed responsibility. The report indicates that trust is difficult to describe because it is perceived as an abstract phenomenon. Also shows the importance of trust in organisations with distributed responsibility, because trust makes relationships and delegation more effective. Competence, communication and understanding are factors that the report present as factors that has influence on creating trust. To retain trust the report argues that continuously work with competence and communication will be needed. Key words: Decentralisation, distributed responsibility, organisational trust, trust, create trust, retain trus

No full textIncorporation of feed and fecal waste from salmon aquaculture in great scallops (Pecten Maximus) co-fed by different algal concentrations
No full textJuvenile scallops of Pecten maxiumus were studied to see the capability to clear out and incorporate salmon feed and feces (30 µg L-1). Algae were also given, in a low and high concentration in addition to feed and faeces, to mimic a winter and summer situation in Norwegian waters. Rhodomonas baltica and Chaetoseris muelleri were provided in a concentration of 50 µg L-1 and 300 µg L-1. The feeding trial lasted for 27 days. Clearance rate was measured to study filtration characteristics, while fatty acid profiling and stable isotopes of nitrogen and carbon were used to trace the uptake of salmon feed and feces in the digestive gland and muscle of juvenile scallops (30–35 mm shell height). The results show that the scallops could clear out and retain both salmon feed and feces particles, although at a statistically lower clearance rate than the algae. Fatty acid profiling revealed that the scallops assimilated and incorporated the consumed salmon feed and feces, given with either high or low algae concentrations, in their tissues, where the fatty acid C18:1n9 was used as a tracer fatty acid. The digestive gland of the scallops that were fed salmon feed and feces contained a higher share of C18:1n9 than those that were only fed algae. The digestive gland reflected the fatty acid composition of the diet, while the fatty acid composition of the muscle, which also changed, reflected a more complex relation between diet and metabolic processes in the tissue. The use of stable isotopes of carbon and nitrogen to trace food sources was inconclusive in this study due to low differences between samples fed different feeds. Fatty acid profiling was a more sensitive method for tracing low concentrations of salmon feed and feces in the algae diet of scallops. Our results suggest that P. maximus could be a candidate for integrated multi trophic aquaculture (IMTA) and that scallops have the potential to utilize small particles of wasted salmon feed and feces during a winter situation with low phytoplankton concentration and during an algal bloom in Norwegian waters.publishedVersionCopyright © 2019 Bergvik, Stensås, Handå, Reitan, Strand and Olsen.

The Potential for Upscaling Kelp(Saccharina latissima) Cultivation in Salmon-Driven Integrated Multi-Trophic Aquaculture (IMTA)
No full textIntegrated multi-trophic aquaculture (IMTA) has the potential of reducing open-cage fish farming impacts on the environment while also introducing new value chains. The aim of this study was to investigate the growth and composition of the kelp Saccharina latissima in salmon-driven IMTA, and to assess the spatial extent of the influence of salmon derived nitrogen in order to evaluate the upscaling potential for IMTA. S. latissima was cultivated 100, 200, and 1,000 m east and 1,000 m west of a 5,000 tons salmon farm in Western Norway from February to September 2013. The proportion of salmon derived nitrogen available for the kelp showed a clear decline with distance from the farm. Accordingly, the kelp cultivated near the salmon cages grew faster during the spring season, and growth rate decreased with increasing distance from the farm. A spatially explicit numerical model system (SINMOD), including compartments for dissolved nutrients and kelp growth, was tuned to the field data and used to investigate the potential for upscaling IMTA production. The model was used to introduce a new metric—the impacted area IA—for the areal effects of IMTA in terms of the increase in production by IMTA. The model showed that a 25 hectare kelp farm in the vicinity of the studied salmon farm could take up 1.6 of the 13.5 tons of dissolved inorganic nitrogen released during kelp cultivation, amounting to almost 12% of the ammonia released during the cultivation period from February to June. The 25 hectare kelp farm would have a production yield of 1,125 tons fresh weight (FW), being 60% more than that of a non-IMTA kelp farm, while a 20% increase of kelp FW could be obtained over a 110 hectar area in salmon-driven IMTA. To achieve an even mass balance, an area of approximately 220 ha−1 would be needed to cultivate enough kelp to fix an equivalent of the nitrogen released by the fish.publishedVersionCopyright © 2018 Fossberg, Forbord, Broch, Malzahn, Jansen, Handå, Førde, Bergvik, Fleddum, Skjermo and Olsen.

Development of the Verona coding definitions of emotional sequences to code health providers’ responses (VR-CoDES-P) to patient cues and concerns
No full textObjective: To present a method to classify health provider responses to patient cues and concerns according to the VR-CoDES-CC (Del Piccolo et al. (2009) [2] and Zimmermann et al. (submitted for publication) [3]). The system permits sequence analysis and a detailed description of how providers handle patient's expressions of emotion.
Methods: The Verona-CoDES-P system has been developed based on consensus views within the "Verona Network of Sequence Analysis". The different phases of the creation process are described in detail. A reliability study has been conducted on 20 interviews from a convenience sample of 104 psychiatric consultations.
Results: The VR-CoDES-P has two main classes of provider responses, corresponding to the degree of explicitness (yes/no) and space (yes/no) that is given by the health provider to each cue/concern expressed by the patient. The system can be further subdivided into 17 individual categories. Statistical analyses showed that the VR-CoDES-P is reliable (agreement 92.86%, Cohen's kappa 0.90 (+/- 0.04) p < 0.0001).
Conclusion: Once validity and reliability are tested in different settings, the system should be applied to investigate the relationship between provider responses to patients' expression of emotions and outcome variables.
Practice implications: Research employing the VR-CoDES-P should be applied to develop research-based approaches to maximize appropriate responses to patients' indirect and overt expressions of emotional needs. (C) 2010 Elsevier Ireland Ltd. All rights reserved
