AIS i havets och tankens strömmar : En etnografisk studie av nautikers användning av transpondersystemet AIS

An ethnographic study loosely informed by the theoretical framework of distributed cognition was carried out in order to describe how mariners have adopted the Automatic Identification System (AIS) in their work practice, or"made the technology their own". AIS is a transponder-based identification and communication system that allows ships to automatically identify and track each other. In addition to facilitating the identification and tracking of ships, objectives behind the introduction of AIS are to"simplify informational exchange", and"provide additional information to assist situation awareness". Participant observation and interviews were made at four different ships, as well as at two shore stations. A focus group was also held at a maritime conference.

Planering och kunskapsöverföring i ideella projekt

Kunskapsöverföring har ansetts vara av vikt inom företag och organisationer för att bevara kunskapen, informationen och för att kunna förmedla den vidare till andra medlemmar. Studiens primära syfte var att genom forskningsteorier och intervjuer effektivisera Rädda barnens Ellen och Allan projekt i deras kunskapsöverföring. 5 aktiva medlemmar inom Ellen och Allan projektet intervjuades samt 1 kontrollintervju genomfördes med en rutinerad projektledare från Svenska kyrkan, för att få fram dennes syn på projektets nuvarande situation gällande kunskapsöverföring.     Resultatet visade att det finns en viss otrygghet i rollerna och framförallt hos projektledarna, som inte har någon specifik roll- eller uppdragsbeskrivning. Genom resultatet kunde vi även se att kunskapsöverföringen bör vara ett ingående moment i organisationens projektbeskrivning för att det ska fungera på bästa sätt. Fysiska möten och god kommunikation mellan deltagarna bör även prioriteras för att effektivisera kunskapsöverföringen inom projektet..

Utbetalningspolitik i Sverige : En studie om utdelningar och återköp i svenska börsföretag

Följande uppsats undersöker hur svensk utbetalningspolitik har utvecklats under åren 1992-2012. Urvalet består av de företag som under våren 2014 var noterade på Stockholmsbörsens ?Large?, ?Mid? eller ?Small Cap? lista. Återköpens andel av den totala utbetalningsandelen visar sig inte vara lika hög som andra internationella studier har visat. Det är istället utdelningarna som utgör merparten av de totala utbetalningarna.

Utveckling av nyckeltal : - ett redskap för prestationsmätning i idrottsförbund

The purpose of this thesis is to examine whether institutional ownership has an influence on CEO compensation in companies where the institutions have invested. In order to fulfil the purpose of the thesis a quantitative study was carried out within the Swedish corporate context where we have studied Swedish institutional investors and companies quoted on the Stockholm Stock Exchange. Our period of study was the financial year of 2007.The empirical questions at issue is; Was there a connection between Swedish institutional ownership and the size of the CEO compensation, and, does Swedish institutional ownership lead to a certain type of CEO compensation in terms of structure?Our results did not suggest that an increased institutional ownership neither leads to a certain type of salary level nor a certain kind of salary structure. These results contradict earlier American research, which has been done within this area and has previously shown a secured connection.The reasons for our results may be many and it is difficult to state any concrete conclusions to why we received differing results.

VD-ersättning och ägarkoncentration: En studie om ersättningsnivåerna i svenska börsbolag

This study examines whether the ownership structure of Swedish firms contributes to explain the variations in executive pay. A regression analysis was performed on 102 companies listed on the Stockholm Stock Exchange. The analysis suggests a negative relationship between ownership structure and executive pay after taking company profitability and size into account. The result is in line with previous studies and the agency theory. This indicates that large shareholders have a stronger position in Swedish companies or that large shareholders monitor the management to a larger extent, rather than providing incentives.

Dagens amerikabrev : Det är precis som på TV

This master thesis is looking into the stories on the internet forum www.resedagboken.se. The stories of Swedish teenaged exchange students in the U.S. are studied and the main purpose is to see both what they are writing about and the reason for why they are spending their time writing down their experiences in a public forum.Even though most of the teenagers here are writing with a specific audience in mind, all the stories are free to anyone to take part of and this causes a difficult position for the teenagers who often seem to forget the public point of view when they are telling about their personal lives.The study is divided into two parts. The first one looks into the content of the stories and the other one focuses on the storytellers and their reasons for writing. The teenagers are writing both a lot about their everyday lives in their new environment, but also a lot of things to keep in touch with what their friends and family in Sweden are doing.
