Enumerating Atlantic salmon smolt production in River Vindelälven based on habitat availability and parr densities : consequences of using different density estimation methods

Habitat mapping was conducted in the main stem of River Vindelälven in the autumn of 2009 along the salmon distribution area. The aim was to estimate the quantity of potential reproduction areas, including spawning and juvenile rearing habitats. The mapping included 61 km of various stream sections along the river length of 269 km. The total area of stream habitats was estimated to 647 ha of which 396 ha (61%) were considered as either potential or optimal juvenile nursery habitats. The area of these two habitat classes were used to estimate the smolt production in the river by using electro fishing densities of juveniles (0+ per 100 m2).

After establishment closure : Individual characteristics that determine re-employment probabilities of displaced workers in Sweden

This paper studies the relationship between individual characteristics of displaced workers and the probability of re-employment. A competing risks hazard model is used, distinguishing between exits from joblessness to self-employment and to paid-employment. All individuals between 25 and 55 years of age, at the time of displacement, that suffered from at least one year of joblessness after being displaced between 1990 and 1998 due to establishment closures that occurred between 1990 and 2001 are included. This allows for the closure procedure to be between one and three years long. Each individual is followed, from the year of displacement until the year of re-employment or at the latest, ten years after displacement.

När kommuner hänger med : En kvalitativ studie av hur åtta svenska kommuner har organiserat och använt sig av sociala medier i den egna verksamheten när det saknats officiella riktlinjer för detta

Title: When municipalities are keeping upAuthors: Hansson Käll, Ida; Jonasson, MikaelaTutor: Waks, CarolineCourse: Bachelor thesis, 15hp, Department of Business Studies, HT 2010Background: During the recent years social media has evolved into a powerful communicative medium. From an organizational standpoint social media has become a way for organizations to get closer to, and create a dialogue with, their environment. Swedish municipalities have began to use social media in their daily communication with the environment, but a problem has been raised about how public organizations should organize their social media when formal guidelines from the government are missing.Objective: The objective of this thesis is to examine how eight Swedish municipalities have organized their use of social media due to the lack of official guidance from the government, and also what difficulties that have occurred during this process.Method: The method used is qualitative with data collected through interviews with one respondent from each municipality.Results: The result show that the organizational solutions varies through each municipality but also the choice of social media. It has been important for municipalities to have someone in charge of the new communication tool since social media is a fast and communicative channel. Seven out of eight municipalities have already developed or are in process of developing their own formal guidelines on how to use social media.

Utvärdering av en subjektiv metod för att skatta mängden trädbiomassa längs vägkanter :

Forest biomass is becoming an increasingly important source of renewable energy, and thereby the demand is increasing. There is currently 213 000 km of forest roads in Sweden that could be suitable for biomass harvesting. Harvest of biomass along forest roads both provides biomass and maintains the quality of the roads. Currently, the volume of biomass along roads can only be assessed post harvest, chipping and industry deliverance. As the decision of whether or not to harvest should preferably be based on more than experience, the TJ-method has been proposed. The TJ-method is a subjective method to quickly determine the dry matter quantity with the assessment being conducted from the roadside.

Havremalt : relansering av en hälsokostprodukt

Launching and marketing a health food product is associated with larger problems than a launch of a traditional food product. There are several sales channels that can be used for a health food product, for example the product can be sold as a traditional food product, natural health food product or as a prescription drug. A smaller company can however experience problems while launching its product as a prescription drug because of the large costs associated with this particular sales channel. There is often no other alternative than to launch the product as a traditional food product, this can however create other problems because of the existing regulations on what can and cannot be mentioned in the marketing of a health food product. The limited amount of information about the product that can be enclosed together with it makes it hard for a company to differentiate and position it on the market.

Förbättrad tidsuppskattning för IT-projekt

Det finns olika strategier och många olika metoder inom strategierna för att tidsuppskatta ett IT-projekt. Dessa strategier och metoder skiljer sig mer eller mindre åt och många gånger har företag egna metoder för tidsuppskattning. Dessa strategier och metoder har samma syfte, vilket är att göra så noggranna tidsuppskattningar som möjligt för att undvika försenade projekt. Examensarbetets syfte är att visa på hur LexiConsult AB kan förbättra sina tidsuppskattningar av inkommande IT-projekt genom att följa studiens rekommendationer, vilket leder till bättre tidsuppskattningar och nöjdare kunder. Undersökningen har utförts genom en litteraturstudie, där genomgång av de olika delarna inom IT-projekt skett.

Det norska energideklarationssystemets konsekvenser för äldre byggnaders karaktärsbärande värden

Roughly 130 000 dwellings have been officially registered since Norway as of summer 2009 passed their bill ?Energimerkeforskriften? on energy performance certificates in buildings. The main objective is to decrease the total amount of national energy consumption by producing a methodology of calculation of the integrated energy performance of buildings as well as proposing cost effective measures to lower each building?s energy consumption. As the measures should not contravene nor be incompatible with the intended quality and character of the building, the ?Energimerkeforskriften? exempts buildings that due to their historical and cultural values are protected cultural heritage legislation. The current system offers a couple of professional certification alternatives, but when two online semi-automatic methods developed specifically for non-professionals are by far the most used, and since the methods of calculation primarily have focused on modern building materials and construction, the rest of the historical building stock stands literally unprotected by incorrect performance certificates and high-risk energy efficient measures. The objective of this thesis is to identify if the current Norwegian energy certificate system poses a threat to older buildings.

Mätning av träddelar och flis på Dåvamyran, Umeå energi :

The moisture content in 10 deliveries of tree parts and 10 deliveries of wood residues were measured with different methods to analyze the quality of procedure used at Dåvamyran today. At the same time a survey was made on the measure procedures used at heating plants in Sweden The majority of the heating plants in Sweden use weight and moisture content as base for payment but at some plants only volume. The moisture content is usually estimated by drying wood chips in an oven but few plants a visual estimation is used. At few plants moisture content is estimated spectroscopicily. The techniques using near infra read light and other electromagnetic are still at a test stage. The methods of measurement used today are quit unreliable for the individual deliveries and there is a risk for systematic mistakes.

Internkommunikation på Gruvön : Modern kommunikation inom industrin

The bulk of the research within the field of media and communication is concentrated at theforefront of development, studies focus on modern companies and modern communication.However, many people work in the industry, where the conditions for communication are partly different. The aim of this study is to explore the possibilities for internal communication that the employees have at the base industrial company of Billerud Gruvön, Sweden. How important do they feel that communication is? Can the internal communication within Gruvön be described as modern, where dialogue between the staff is possible, or as orders from the top down to the bottom of the hierarchal structure?These are our research questions:Which channels are used for communication within Gruvön, and how are they used?How important do the employees deem the internal communication to be?Can the communication within a hierarchal industrial company such as Gruvön be described as modern, where dialogue is at the center, or does the communication consist basically on orders from the top down to the bottom of the chain?Our research is based on the following theories: Communication, Organizational communication, Internal communication and Organizational culture. We have looked to earlier research such as the doctorates of Simonsson (2002) and Johansson (2003) to further our understanding.The methods used are interviews with operators, middle management and the informationofficer at Gruvön.

Bedömning av ögats ackommodativa respons- en jämförelse mellan aberrometri och dynamisk retinoskopi

Syfte: Syftet med denna studie var att undersöka om det finns några skillnader i den ackommodativa responsen när den fastställs med tre olika mätmetoder. De utvalda metoderna för denna studie var dynamisk retinoskopi i form av Nott och Monocular Estimation Method (MEM) samt en COAS-HD VR aberrometer.Metod: 29 personer (7 män och 22 kvinnor) deltog i studien, vars medelålder var 23,6 ± 3,1 år. På varje enskild patient gjordes en subjektiv refraktion med en efterföljande mätning av dess ackommodativa respons med tre olika mätmetoder på ett 40 centimeters arbetsavstånd. Resultaten av studien analyserades med hjälp av Repeated Measures-ANOVA och ett post-hoc test i form av Sidak´s. Överensstämmelsen mellan metoderna redovisades därefter visuellt i form av ett Bland-Altman plot.Resultat: Det visade sig att alla tre metoder gav liknande värden på den ackommodativa responsen, vilket resulterade i att det inte fanns en statistiskt signifikant skillnad mellan metoderna (p = 0,1103) enligt Repeated Measures-ANOVA.

Kronandelsrelaskopering, en ny metod för att fastställa gallringsbehov?

In today´s forestry, assessments of needs for thinning are based on basal area measurements. This is an indirect measurement. The approach and the developed assessment tables are based on an assumed production forest, which implies that management proposals in stands that deviate from the basic model may be misleading. Since Walter Bitterlich in 1948 launched the idea of the relascope, several modifications have been developed for different purposes. In common is that all are based on a certain angle measurement principle.

Hur kommunicerar fackförbundet Unionen med sina medlemmar? : Påverkas kommunikationen av det minskade antalet lokala klubbar?

The purpose of this study is to investigate differences of how the Swedishemployees union ?Unionen? communicates with its members, on one hand thosewho are members of local union clubs and on the other non-club members. Thenumber of non-club members has increased due to labour market changes implyingthat workplaces have been fragmented and hence affect the possibility to form localunion clubs.The questions posed in the study are: How does Unionen communicate with itsmembers? How does the communication differ between club members and non-clubmembers? What are the preferences of Unionen´s members as far as communicationwith the central organization? What kind of information do the members seek andhow do they find it? What values does Unionen represent? Are there differencesbetween the messages that Unionen is sends out and how members and non-clubmembers, respectively, perceive them?A case study method has been used applying both quantitative and qualitativeanalyses. Quantitative methods have been used in illustrating the number ofdiscussion subjects at Unionen´s website, the members needs for receivingcommunication and channel usage while qualitative methodologies have been usedin interviews with Unionen´s members, club chairmen and union representatives aswell as semiotic picture analyses and analyses based on methods of Uses andgratifications theory.One conclusion of the study is that two significant differences of communicationhave been found between members and non-club members.
