Variationer- En intervjustudie om sexualitet och uppfattningen av det normala

Can the need for inclusion result in certain social norms remain unchallenged, and over time become hard to identify? To ?fit in? and be accepted in different social contexts we have to behave according to the dominating rules and conventions. We accept characteristics and make use of attributes specific for the group we want to be a part of. When we accept these attributes we contribute to keep the concept of them alive. Further on these attributes will be picked up by the next person who wants to become a part of that specific context.

Utvärdering av en ny selektionsmetod för hingstsperma : med avseende på membranintegriteten och membranstabiliteten

Today, equine breeding is based on performance and conformation, resulting in a vast variation in fertility among different horses, with noticeable economic losses as a consequence. The horse breeding industry is therefore in need of methods that diagnose the spermatozoa concerning their quality and provide the best sperm for AI. The commonly used selection methods for sperm today are: centrifugation, where extender is added, the sample is centrifuged and then resuspended; swim-up self-migration; adherence separation; and density gradient centrifugation. However, none of these methods are in used routinely in practice before inseminating mares with fresh or cooled semen. The aim of this study was to evaluate a new selection method, Single Layer Centrifugation (SLC), and its effect on sperm viability. The viability was analyzed with regard to membrane integrity and membrane stability of ejaculated spermatozoa.

Kan biologisk mångfald ökas i ett avsatt skogsområde? : skötselplan för Storskogsberget på Holmen skogs marker, distrikt Umeå

The biodiversity of the Swedish forest has degenerated since the beginning of the 19th century when fire suppression and large scale logging first occurred. Together with a changed land use, these actions today have had a negative influence on many forest dwelling species, due to gradual reduction of natural processes, successions and different structures from the forest ecosystem. The Swedish Forest Act, together with different environment certifications, have today encouraged private persons and forest companies, among them Holmen Skog, to work actively to improve nature conservation. The aim of this study was to, by field inventories of already existing nature values, literature studies, recommendations from scientific reports and ecological gap analysis as a basis, make a management plan, for a non-production area, to conserve or improve the prerequisites for biodiversity. ?Storskogsberget? is located in the coastal area of Västerbotten County, 35 km from the city of Umeå.

Nyckeln till den positiva spiralen - En studie av musikers syn på sitt övande

Title: The key to the positive spiral - A study of musicians views of their practicing. The purpose with this paper is to make clear how continuous practicing on one element affects not just the specific part but also other things. Is it possible to find a positive spiral where everything can be better if you focus your practicing on one thing? Can this element if it is done daily in a qualitative way transform to a key which will help you to unlock the door to the positive spiral? Are there more keys to find? I am going to reflect my ideas in this paper through a philosophical, psychological and the brain sciences perspective. Quality in action is going to be compared with the quality that you need to set a successful goal, and to reach the state of mind called flow you will need both these qualities.

Iterera, iterera, iterera : En studie om hur en upprepande designprocess kan förbättra användbarheten i Provbankens interaktiva distansprov

Provbanken är en del i ett nationellt provsystem som är tänkt att vara ett bedömningskomplement till existerande prov i gymnasieutbildningen. Växjö universitet har varit delaktig i utvecklingen av prov för de yrkesinriktade ämnena sedan 1997. Eftersom innehållet i dessa numera webbanpassade prov är det väsentliga, måste utformningen av provet göras lättförståelig. Användbarheten måste m a o vara självklar och inte ställa till problem för användaren. Som en av utvecklarna av dessa interaktiva prov, ville jag finna ett sätt att minimera problemen och öka användbarheten.

Mellan fri vilja och datadriven exploatering: En studie om drivkrafter, medvetenhet, makt och ansvar inom onlinecasinomarknaden

This essay examines the limits of marketing strategies in the online casino industry, focusing on how data-driven and advanced marketing practices influence consumer behavior and contribute to problematic gambling consumption. By observing the online casino industry, the study identifies how companies use sophisticated data analysis methods and psychological techniques to attract and retain customers, raising significant ethical and social issues. The study highlights three key perspectives: the consumer's, the producer's, and the legislator's. From the consumer's perspective, it explores how various consumer behaviors, from responsible gambling to problematic overconsumption, are influenced by marketing and gaming experiences. This includes an analysis of how cognitive limitations and psychological biases can lead to irrational decisions and an increased risk of gambling addiction. From the producer's perspective, it examines how gambling companies use marketing strategies and technologies to increase profitability and what incentives they have to take social responsibility according to modern Corporate Social Responsibility (CSR) principles. It appears that companies do not see CSR as a business goal beyond the risk of current and future regulatory compliance requirements and policy changes. From the legislator's viewpoint, the current regulatory framework for the gambling industry is discussed, including the changes that occurred in 2019 when the special monopoly form we had in Sweden was transformed into a license market.

Vattendragsrestaurering i teorin och fiskinventering i praktiken : en litteratur respektive metodstudie

Running water-pathways have played an important roll in Sweden and frequently been manipulated. One profound change was made during the period of logging when streams were cleared from obstacles as big boulders, sharp bends and side-streams. Dams and different constructions gave control of the stream water and the streams became channel-like with a homogen structure. This interference gave problems for many fish populations and resulted in a shortage of feeding habitat, over-wintering habitat, spawning habitat, unnatural flow regimes, sedimentation, unnatural temperature fluctuations. Many of these historical changes of the watersheds are now subjects for restoration, ie., bring back the streams to what we believed it was before the change. However, what once existed in terms of complexity is now gone and difficult toreplace.

Redovisningskonsekvenser vid förändringen av pensionsredovisningen

AbstractAuthors:Stefan Harrå and Magnus BjörkAdvisor: Markku PenttinenTitle: Accounting Consequences of the change in pension accounting Background to problem: When the revised IAS 19 comes into force January 1, 2013, it means that two of the three accounting principles for defined benefit pension plans are disappearing, including the corridor method. The corridor method has made it possible for companies to defer its actuarial gains and losses. Now that the corridor approach abolished then the unrecognized actuarial gains and losses immediately be covered by equity, which involves very large amounts of some companies. Why the amounts have grown so big is much because of the discount rate. The discount rate is a controversial parameter, and there is disagreement on how it should be fixed.Purpose: The purpose of this thesis is to examine the accounting implications this will have for the company applied the corridor method, and if there is some parameters in the actuarial assumption that is more important than others.Methodology: The thesis has mainly been based on a qualitative research through qualitative interviews with a small sample that is affected by this change.

Assessment of food retail business sustainability : the case of Konsum Värmland

Public concern and the need of responsible way of doing business have brought forward the issue of sustainability at the forefront of discussion in the last decade. Even though, food retailers are playing an important role in the economy, they are exposed for criticism by media and consumers for any socially and environmentally irresponsible business practices because, the potential environmental and social impacts from their operations are significant. These impacts need to be recognized and properly addressed. The main objective of this study was to assess the sustainable business management of a cooperative food retail business in Sweden, known as Konsum Värmland (KV). The necessary data and information on history and status of KV, and its practical activities concerning the implementation of sustainable development programs as well as the motivation and challenges encountered by KV during the implementation were gathered via reviewing different documents, research papers and press releases; interviewing decision makers and other personnel in KV and other researchers from Swedish University of Agricultural University who have investigated KV.

Brand i Fulufjällets nationalpark : en brandhistorisk analys med förslag för framtida skötsel

Fire has historically been of great ecological importance in the boreal forests of Sweden. The forest fire regime has, however, varied between different parts of the country. The objective of this thesis is therefore to investigate the fire history in Fulufjället National Park and, on this basis, give suggestions for future fire management. The reconstruction of fire history was done by cross-dating fire scars in samples taken from living and dead Scots pine (Pinus sylvestris). Local fire chronologies were established at 17 points in the forests in and around Fulufjället National Park by cross-dating fire scars on 54 samples. The oldest year-ring dated from year 968.

Förbehandlingstekniker och LCA för rötning av organiskt avfall : Modellkonstruktion och Utvärdering med ORWARE

The goal of this master thesis project was to develop computer models of some plausiblepretreatment techniques and to assess the potential benefits/costs of using pretreatment andanaerobic digestion for waste management of organic waste from a system perspective. Forthis purpose a computer program called ORWARE has been used. ORWARE (organic wasteresearch) is a program for making life cycle assessments of waste management. As the mainpart of the project work the ORWARE system has been provided with three new models ofpretreatment techniques. The additions consist of: One model of pretreatment with ultrasound,one model of thermal hydrolysis and one model of a screw press.

Motståndet mot religiösa yttringar i det offentliga rummet : En kvalitativ studie om hur muslimska religiösa yttringar påverkas av de rådande sociala normerna

The study's aim was to increase knowledge about the resistance of the Muslim religious expressions in the public sphere and its emergence on the basis of the case around the opposition to call for prayer. The study was conducted through the use of the qualitative research approach through interviews with informants who have a pronounced aversion regarding the existence of the public call to prayer in Sweden. The study's questions have been answered by an analysis of the empirical material by using different theoretical points that illustrate how Western standards are valued higher than the other, in the various standard systems. The view of the Muslim religious practices depicted by informants through an interpretative framework that is characterized by Islamophobic arguments that are considered to be incompatible with Western culture and the principles of the secular state striving. Such discourses can create an uneven distribution of power between Muslims and non-Muslims on the basis of the West's representations of Orientalism explained based in ethnocentric knowledge.

Landskapsplanering och konnektivitetsförbättringar inom värdetrakter i Västerbottens län :

According to the Swedish strategy for forest protection, additionally 40 000 ha productive forestland will be protected in the county of Västerbotten, between 1999 and 2010. A national project was carried out to distinguish the proportion of forest with a high biological value, in all counties. The project resulted in demarcation of small landscape areas or small ?biological value regions? (bvr), with higher concentrations of forests with conservation values and red listed species than the surroundings. In Västerbotten, 26 such bvr?s were identified and the Counties Agency and Forest Agency in Västerbotten developed a regional strategy for forest conservation to standardize the forest protection process.
