Analys av åldersstrukturen hos sik (Coregonus lavaretus) i sjöar utan gädda (Esox lucius)

Development of morphs within European whitefish (Coregonus lavaretus), might be considered as a beginning of a sympatric speciation process. Unpublished data suggests that presence of the keystone piscivore northern pike (Esox lucius) is the main driver of sympatric divergence in European whitefish (Coregonus lavaretus). Using introduced whitefish populations as controlled experiments, it is possible to determine when different characters diverge in the speciation process. In this study, I analysed age and growth within European whitefish populations of different age to assess if these characters change over time in absence of pike. With using otoliths from whitefish populations of different age, I was possible to determine individual age, and by measuring the length of the fish, growth was calculated.

Trovärdighet på onlinebutiker inom mode : En kvalitativ studie av den estetiska utformningens påverkan på trovärdigheten vid ett första intryck

E-commerce is becoming more common in Sweden and many Swedes buy clothing and sporting goods online. Online fashion retailers offer a visually pleasing range of products, which places greater emphasis on the aesthetic design of the online retailer. This paper examines how the perceived credibility of an online fashion retailer is influenced by the aesthetic design through a first impression. This study was conducted through ten interviews where the informants observed, assessed, and then discussed the online fashion retailers that were used in this study. Results show that recognition of an aesthetic design and a perception of usability and professionalism affects the perceived credibility in a positive way.

Modulbyggd förskola - Framtiden?

In 1999 the childbearing increased, which in combination with the closure of a number ofpreschools led to the shortage and reduced capacity in available places for youngchildren. The lack of places in preschools has led us to try to find a solution to theproblem and in order to solve the problem we have interviewed personnel of preschoolsin Halmstad. The persons we met were asked to list advantages and disadvantages oftheir preschool and also to come up with innovative solutions and new ideas of how todevelop a satisfactory preschool. This was the basis for us when we drew our drawingsand our main objective was to find a new template for the development of pre-fabricatedpreschools.When drawing a new and modern preschool a number of considerations have to be made,first of all the main objective for the children is play and playtime, a second objective issound reduction and laws about sound reduction. Another consideration is how toconstruct the building and which method to be used, for instance should industrialtechniques be considered and pros and cons be listed.The main disappointment amongst the preschool personnel was that they had noinfluence in the planning stage of the new development of the preschool.

Påverkande faktorer för grotens fukthalt

The aim of this study was to investigate how seasonal variations affect the quality of logging residues. The study was hosted by VIDA Energy. Logging residues can be processed and transported within different systems. Today the dominant systems are chipping at landing and bulk transportation of logging residues. In these systems the handling of the logging residues are carried out in the same manner up to the landings. Moisture content at the time of chipping is the primary quality parameter. Fine fractions of logging residues are strongly dependent on moisture content in storage.

Hedonisk prisbildning på bostadsrätter : En tvärsnittsanalys av bostadspriserna i Stockholms län

Den svenska bostadsmarknaden har under en längre tid varit ett hett diskussionsämne i media. Regelbundet beskrivs den svenska bostadsmarknaden som övervärderad. Ovissheten kring var marknaden befinner sig värderingsmässigt, väcker intresse att undersöka hur en bostadsrätts olika egenskaper påverkar dess värde, alltså vad individer är beredda att betala för i en bostadsrätt.?Hur mycket är konsumenten villig att betala för olika egenskaper hos en bostadsrätt, så som: boarea, våningsplan, hiss och antal rum??I studien utförs en empirisk tvärsnittsanalys, med observationer insamlade från och med första augusti till och med sista oktober 2014. Bostadsrätterna som är inkluderade i studien är geografiskt belägna i Stockholms innerstad (Kungsholmen, Norrmalm, Södermalm, Vasastan samt Östermalm).

Den "perfekta" chefen; En studie om fem anställdas perspektiv på chefsrollen

Abstract Thou there are much written about management, are there, according to Mintzberg no simple definitions regarding how managers should operate towards other co-workers or employees. This essay outlines a perspective for study of managers, from an employees point of view. The study was preformed at one private company, and the empirical data was gathered from five employees. The methodological approach contained qualitative methods based on semi-structured interviews. By using this method, a deeper understanding regarding the questions was desired.

Hur stödjer systemutvecklingsmetoder kommunikation mellan systemutvecklare och kund?

AbstractThis paper discusses how system development methods today support communication between system developers and their customers and end users. Today there are many system development methodologies with different aims and emphases. It is difficult, however, to find among these methods those who promote good and effective communication with customers because so many of these are very technically rooted and not as much directed towards the soft aspects of systems development - i.e. Human aspects. Our own experiences tells that a simple interview can be initialized without us having an idea what to ask the customer about or how to structure it up - nonetheless it?s done, but the outcome is just chance.

En studie av sambandet mellan kvarstående bias och kostnad vid selektiv granskning i undersökningen Kortperiodisk Sysselsättningsstatistik : Analys av parameterval i verktyget Selekt

Det har pågått ett intensivt utvecklingsarbete på Statistiska Centralbyrån (SCB) under de senaste åren i syfte att standardisera och effektivisera statistikproduktionsprocessen. I detta utvecklingsarbete har fokus främst riktats mot processerna insamling och granskning. Ett flertal studier har visat att det finns potential att reducera granskningens omfattning samtidigt som den övergripande kvaliteten i undersökningarna bibehålls. För att uppnå detta krävs att nya arbetssätt, metoder och verktyg utvecklas och implementeras.Den traditionella ansatsen på SCB har varit att i granskningsprocessen försöka hitta och rätta alla databearbetnings- och mätfel. Ingen skillnad har gjorts mellan stora och små fel eller om felen har någon effekt på statistiken eller inte.

Radomoptimering för luftburna störsändarkapslar

These studies are done in behalf of Saab AB AVITRONICS in Järfälla in the form of a thesis atthe Royal Institute of Technology in Stockholm.The task was to examine the parameters that plays a role in the construction of modern radomesoperating in broadband applications.This was interesting for Saab to get an indication of which way they should go at the newdevelopment of radomes for the next generation of equipment for electronic warfare.After a thorough analysis of the influencing parameters, a optimization application was made toget a automated way to get a radome design by specifying data on the radome size, airloads,materials, etc.This is to minimise the time of the laborious work that radome development.inply.This was solved by letting ANSYS calculate the strength of the radome structure and MATLABcalculate electromagnetic data and cost models of different sizes and materials.All these parameters woven together with the optimization tool modeFrontier picks data from therespective program and perform an optimization algorithm and then iterate a step and sends thisdata to calculation programs for the new input data. In the end, we have received a convergedpoint with our optimal solution.For the presumptions and limitations for which applied for this thesis, the result was prettyintuitive. That is to say that the smaller radome - the less materal is needed and lowermanufacturing costs results in the cheapest solution possible. The reality is not so simple. Whereyou have to take more of the electrical details such as the effect on the transmitter as a majorfactor..

Från digitalt utanförskap till digital gemenskap : En hypotetisk väg till digital gemenskap

We are in an emerging digital society where we are increasingly dependent on the mastery of IT and digital technologies to better carry out our everyday tasks. They cover everything from keeping in touch with family and friends to pay bills and declare. At the same time there are those who have not learned how to use the new technology and live their lives outside of the digital society. What happens to these people, in a society that is becoming increasingly digitized? Do they take harm by being in digital exclusion? It looks like this are issues that will not become less important as digital technology constantly changes.
