Maktstrukturer i svenskt näringsliv: En social nätverkstudie av delade styrelseledamöter i Sverige 1985 och 2005
This paper examines the interpersonal and intercorporate networks of interlocking boardmembers among Sweden's 50 largest publicly traded companies in 1985 and 2005. We find that both the interpersonal and intercorporate networks of 1985 are considerably more coherent and densely connected than those of 2005. The observed changes in social network structure are compared to changes in company ownership in Swedish publicly traded companies during the same period, and it is found that the observed changes in network density and cohesion can be related to a notable increase in the number of foreign board members. These results imply that the social organization of the Swedish system of corporate governance has changed notably during the period. Social network theory suggests that these changes can explain the greater demand for external regulation, decreased homogeneity of board members and increase in board member compensation observed under the period.
Funktionell testning av webbplatser : En fallstudie
Websites are often developed by small businesses, organizations or individuals which may lead to that the testing gets left behind; the focus is on getting a finished product that can be deployed as quickly and as cheaply as possible.Functional testing is important also for websites and a variety of aids exist. With the right tools and methods the development work is facilitated, and it leads to products with fewer faults.This report shows in the form of a case study how an appropriate tool for functional testing can be selected and how it can be used within development of a website. An analysis of the tools available is reported and JSystem is selected as the most appropriate for this case.It turned out that JSystem could not be used fully as intended in terms of deployment, but a well-functioning alternative solution was developed.A number of test cases were created without any unsolvable problems and JSystem performed well. In JSystem test cases in Java are created in Java, which gives a high flexibility..

Farmers? main reason for crossbreeding dairy cows is that they have seen a decline in functional traits, especially in the Holstein breed. Throughout crossbreeding, the farmers can combine functional and production traits of different dairy breeds and utilize the heterosis effects which emerge when two or more breeds are crossed. Results from different studies with Holstein crossed with Jersey, Brown Swiss, Normande and Scandinavian Red have shown that the crosses had higher fertility, longer productive life, had fewer stillborn calves and had easier calvings than purebred Holstein. The Holstein crosses have shown very good results and sometimes even better than the purebred Holstein for fat production, which gave higher amount of energy corrected milk (ECM) and higher income for the farmers.
Productivity of integrated harvesting of pulpwood and energy wood in first commercial thinnings
The aim of this study was to quantify the productivity and the costs of different harvesting systems (teams), containing harvesters equipped with accumulating harvester heads and forwarders, in first commercial thinnings were an integrated harvest of pulpwood and energy wood were performed. In the beginning the plan was to study and measure 20 sites before and after harvest. Due to storms during the summer of 2010, complete data could only be obtained from 8 of these 20 sites. Seven of these sites were privately owned and one was owned by UPM, all of the sites had been pre-commercially thinned. The mean stem density before harvest was 2578 stems per ha and the mean stem volume was 0.074 m3solid over bark.On average 1518 stems/ha was harvested.
Functional Foods-når hälsobudskapet ut?
Vårt syfte med denna uppsats är att ge en ökad förståelse för hur hälsobudskapet kankommuniceras på förpackningar och i marknadsföring för att underlätta att budskapet når ut till konsumenterna. Vi har använt oss av en deduktiv ansats för att ta fram antagande om hur functional foodsföretag effektivt ska kommunicera sitt hälsobudskap. Dessa antaganden har vi sedantestat med kvalitativa empiriska undersökningar. Våra intervjuer presenteras i ett empirikapitel som sedan analyseras. I teoriavsnittet har vi använt oss av flera modeller och teorier varav två varit av stor vikt.
Kartläggning av Sveriges landstings användning av telemedicin
Sweden's aging population makes the need for a viable health care urgent and telemedicine can be a solution to enable older people to receive or give themselves care in their homes. Furthermore, implementation of telemedicine has the potential to realise profits in society by increasing the accessibility of health care and minimizing travel costs. Sweden?s low population density and geographical configuration makes the advantages of telemedicine even more appealing. To illustrate the differences between the county councils? use of telemedicine and thus increasing the possibility for coordinated care between them, the authors have on behalf of the Innovation Centre at the Karolinska University hospital mapped the amount of telemedicine technologies that are available in the Swedish county councils? today. To collect information an electronic survey and video or telephone interviews were used.
Skötselns och ståndortens betydelse för kärnvedsbildningen i tall
Heartwood has always been a desirable part of the tree, due to it?s superior decay qualities com-pared to the sapwood. How the formation of heartwood works has been known for a long time, but which factors that initiates and stimulates the production are poorly understood. This case study presents the results of a study in which silvicultural treatments and site properties had a key position as factors to the formation of heartwood. According to the hypothesis the amount of sapwood is directly controlled by the size of the crown.
Samspelet mellan IT-avdelning och verksamhet : En studie av hur koordination påverkas av strukturer och social interaktion
Several surveys indicate that corporate leaders still consider the aligning of IT and business functions as a top management issue. The aim of this thesis is to illustrate how coordination emerges between IT and business departments and how formal structures intended to coordinate are influenced by human action. To deepen the understanding of this phenomenon we seek to analyze IT/business coordination from a perspective based on practice theory. A field study was conducted where observations and informal interviews were carried out at the IT department of a global company. The empirical analysis indicate that coordination problems between IT and business departments is in part affected by embedded factors such as different goals and perspectives on how IT is to be used in the organization or how to design IT related processes.
Solokvist eller ensamvarg : Socialt samspel hos personer med psykosproblematik
Background: People diagnosed with psychosis are often described as introvert, isolated and with little or no ability to create and maintain social relationships. While every angle of a phenomena is valid and important, we believe that the first-person perspective provides the only direct access to the diagnosed persons? feelings and experiences.Aims: The aim of this study is to explore how a few people diagnosed with psychosis describe their experiences of social interaction.Method: This study is conducted in a Grounded Theory manner. An analysis has been performed on interviews made with five individuals, all diagnosed with a psychosis diagnosis.Results: The main result of this study is that the self-image is a core factor in the individuals experiences of, and initiative to, social interaction. The social interactions are linked to the individuals own relation to their diagnosis in a dynamic process where all components affect each other in the creating of the self-image.Conclusion: This study concludes that people diagnosed with psychosis is no different than other people when it comes to dreaming and longing for functional social relationships, but that they have some difficulties in actually finding them due to both social stigma and a poor self-image..
Invandrares nätverk och sociala kapital
Abstract The increased focus on social capital theory has made its way into labour economics. This has led to the creation of a vast literature about the use of networks and informal search methods in the labour-market, a literature that to some extent also deals with immigrants search behaviour and their relatively high unemployment rate. Characteristic for the literature in the area is the lack of analysis of actual networks. Which types of contacts do these networks contain; how are the networks used in the labour-market; and which type of network generates a high amount of social capital. These questions are important for the general understanding of how social capital functions, within the labour-market, but also for the understanding of how immigrants use their networks in order to find themselves jobs.
Vad är viktigt? : Läroboken i biologi som förmedlare av kunskapsideal kring innehåll och mening
The aim for this paper has been to examine three textbooks designed for science education in upper secondary school in order to determine whether they convey any specific attitudes regarding what is considered to be ideal knowledge within the field of biology. The main focus has been to investigate if different types of design strategies have been used to emphasize certain values or attitudes and if this proves to be the case, how is this achieved specifically? For this purpose I have conducted several different qualitative linguistic analyses of the textbooks. The theoretical framework for the analyses lies within the main field of critical linguistics and more specifically in the context of systemic functional linguistics. The two main language models I have chosen to use for my investigations are functional grammar and multimodal text analysis. My results imply amongst other things that by conducting an overall assessment of the headlines in the textbooks a fair assessment can be made of which overall attitudes the books convey.
Livskvalitet 2-7 år efter allogen stamcellstransplantation
This is an empirical cross-sectional study with the aim to examine the patient?s comprehension about their quality of life within two to seven years after their stem-cell transplantation with reference to physical, social, emotional, psychological and functional wellbeing and to investigate if the patient groups have disease specific problems. Differences in quality of life between men and women and also between allogeneic and stem cell transplantation with an unrelated donor (URD) were studied. The measurement Functional Assessment of Cancer Therapy (FACT) and the bone marrow transplant subscale (BMT) is a 49 item, valid and reliable measure that was used. The questionnaire was answered by 43 of 47 patients (91%).There is a significant difference between men and women in physical, social and functional wellbeing.
Simulering av valkar i pappersrullar : och analys av de slappa stråk som uppkommer
A baggy paper web has parts that are longer than neighboring parts. One of the assumed reasons for bagginess is thickness variations of the paper. In the roll the thicker streaks then add up to form a ridge. In the ridges the paper is strained and during storage the strain may become permanent. When the paper unreeled it is then baggy.
Fräsch och strukturerad med attityd : Ett examensprojekt om tidningslayout
AbstractPresentation of the problem: The goal with this graduation project is to produce a new visual concept for the student newspaper Campus, this will be expressed in the form of page templates. The page templates will have a visual concept that appears through graphical elements. The client's wishes were that the student newspaper should be audience appropriate, attractive, inviting, reliable, modern and functional to work with.Theory: In order to implement the wishes and in a good way produce a consistent visual concept, we took a starting point in theory of graphic design. This theory has taken many of its principles from aesthetic theory, and therefore have we also used aesthetics to provide a deeper theoretical aspect. The principles we used in graphic design is; how to create a unity in the layout by using basic elements such as text, images, and white space.
Globaliseringens och professionaliseringens effekter på styrelsesammansättningen i svenska börsbolag: En social nätverksanalys baserad på delade styrelseledamöter under perioden 1990 till 2010
The purpose of this thesis is to examine the networks of interlocking directors in the 50 largestSwedish companies on the Stockholm Stock Exchange during the years 1990, 1995, 2000, 2005and 2010 and seek explanations for the observed developments.Our findings indicate that the density and concentration of the network has decreased during thefirst ten-year period and stayed constant during the second period. The development of theoverall network is not consistent throughout all corporate groups. Most notablyHandelsbankssfären seems to experience increased density and connectivity whileWallenbergsfären is experiencing the reverse.The changes during the first ten-year period is deemed to come mainly from changes inregulations pertaining to both the opening for international capital investments as well as looserrestrictions on domestic capital investments. These changes have caused decreased concentrationof ownership, as well as the emergence of new owners, which is reflected in the board ofdirectors.During the second ten-year period the changes are more pertaining to the individual boards andboard members, without flowing through into the overall network. Our findings indicate thatthese changes are caused by the increased professionalization of boards and board work, whichhas gained momentum through the creation of the Swedish Corporate Governance Code..
