This essay set out to propose a problematic interpretation of the socio-cultural perspective on learning. Its purpose is to show how the socio-cultural perspective on learning defines the concept of knowledge in an incomplete way. The aim becomes then that of giving a more comprehensive description of this concept, and, to this end, to construct a new, broader pedagogic discourse. The investigation starts with a deconstructive analysis of Roger Säljö?s socio-cultural text in order to point out the incompleteness of the concept of knowledge.

The giant otter (Pteronura brasiliensis) is listed as an endangered species and scientific litterature concerning its biology and behaviour is scarce. The current study observed a group of three giant otters in a Swedish zoo. First the otters normal behaviour was recorded. Then the aim of the study was to see if the otters behaviour changed when given blue mussels (Mytilus edulis). Furthermore the aim was to see if the otters displayed any tool-using behaviour when given mussels.

Cancer is one of the most feared diseases in veterinary medicine today, and the incidence is higher than ever due to the fact that our companion animals live longer then they did ten to twenty years ago. Cancer is also one of the most common causes of mortality in older companion animals. This literature review will be about two of the currently most common form of cancer treatment of companion animals in Swedish animal hospitals, chemotherapy and radiation therapy. There will also be a section of general nursing care for cancer patients. The section of chemotherapy will describe the indications for choosing chemotherapy, the way to administrate chemotherapeutic drugs, describe specific chemotherapeutic drugs, potential side effects of chemotherapy, and how to handle and store chemotherapeutic drugs safely. The section of radiation therapy will describe the current devices for delivering radiation therapy, describe the indications for choosing radiation therapy and describe potential side effects that radiation therapy may cause.

The purpose with this paper is to examine if tertiary education and democracy have an impact on economic growth. In order to decide how democratic the examined countries are the democracy index constructed by The Economist is used. Besides the two central theories the purpose is also to explain why these variables could affect growth and to examine direct and indirect effects. Indirect effects mean that one variable affects another variable which thereafter has an impact on economic growth.34 OECD countries are compared in order to investigate whether education and democracy are strongly correlated with BNP per capita. Therefore a statistical design is used as method.The empirical results suggest that there is significant correlation between democracy and economic growth.

The purpose to this study is to find an understanding of the effects of how sponsorship can affect companies and their business and at the same time get a better understanding of how sponsorship is or can be used as a marketing tool in today?s marketing. By using a quality research method we have chosen to use a half structured research method to make it possible to find out how sponsorship as a marketing tool can be used from a company perspective in relation to our chosen thesis. To enhance the readers understanding we describe the base of sponsorship and principals for sponsorship, after that describes a deeper perspective of sponsorship, what sponsorship is, and what factors are needed to be taken into consideration. Further on we illustrate the figure that later on will constitute the analysis with attributes like: association, exposure, relations and integrated communication.

The effects of social media usage in a professional context, specifically the effects on social media usage in relation to leadership have been studied in order to determine weather or not usage can be productive for leadership in general. The study concludes that there are several benefits as well as drawbacks to leadership in using social media, but has yet to conclude weather productive or not. This study gives an overview of a relatively unexplored subject.Leadership in terms of leader, communication and group dynamics have been defined and explained in accordance with existing literature. A  brief review of computer and Internet history attempts to explain the formation and evolution of social media. Risks in terms of risks related to leadership and risks related to IT-security are taken into consideration and have been briefly explained.

In today?s society we depend on technology to perform the simplest tasks. Whether we are engaging in conversation with a friend or are navigating in traffic, we are likely to be found with some technological device in our hands. This dependence has grown over a period of time, and many of us have failed to reflect on the impact technology has had on our lives. The emergence of so-called One-to-One projects, where teachers and students gain access to a personal laptop, does however provide an excellent opportunity to do so.

Sleep is a vital part of life. Even so a lot of the mechanics regarding sleep is unknown. The dairy cattle of today live a stressful life, as their high milk yields forces them to eat large amounts of feed and spend a great portion of the day ruminating. Do they have time to get enough sleep? Which factors affecting the need of sleep in dairy cattle are largely un-known.

In 1998 the Swedish Socialist Government initiated a project in order to promote economic growth and to end the discriminating social and ethnic segregation in the greater city regions of Stockholm, Gothenburg and Malmo. One of the goals of the project was and still is to promote political participation in 24 of the poorest areas of the three cities. In a quantitative analysis I evaluate whether or not the project so far has been successful in promoting a specific part of political participation, i.e. electoral participation in communal elections. The results of the 24 poor city areas are compared with a group of 14 likewise poor city areas of major swedish cities.According to my hypothesis, general improvements of the socio-economic status of poor city areas ought to generate positive effects on electoral participation in communal elections.

For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.

The purpose of this bachelor thesis is to find out how information seeking habits and experiences of people in different generations affects their expectations on information retrieval systems like OPAC. Two OPACs are used, one web-OPAC and one mobile-OPAC. The following questions are asked: how can theories about information seeking behaviors explain why and in which way one seeks information? In which way does information seeking behaviors and habits affect the experience of OPAC? Which differences and/or similarities can be found between the web-OPAC and the mobile-OPAC? How does generational aspects affect experiences and preferences in an information seeking context? The theoretical framework of the thesis is information retrieval with several models about information-seeking/searching needs and behaviors. The empirical data contains interviews with nine people in different generations and protocols about two different OPACs.

Today, the management concept of lean has stretched far from its origins in the Japanese automobile industry. When reaching the Swedish restaurant industry, the conditions for a successful implementation of lean change as a result of the high employee turnover and the significant amount of part-time employees characteristic for the industry. Combined with a high-end service profile, these workforce characteristics seem inconsistent with some of the basic principles of lean. By conducting a case study, this thesis aims to investigate the effects of a variable workforce on the enablers for a successful implementation of lean in a high-end service industry. Using a theoretical framework consisting of enablers for an implementation of lean in services, the study finds that the variable workforce inhibits an implementation of lean by complicating the effects of traditional training, as well as the possibility of understanding the lean concept at all levels of the organization.

Today evidence exist that environmental chemicals deteriorate male sperm quality and that testicular cancer is increasing. Bisphenol A (BPA) is a chemical with estrogenic effects used in the manufacture of polycarbonate plastic and are found in, for instance, plastic boxes, feeding bottles and food containers. Much of the research on how men's reproductive ability is influenced are performed on rats. This review article complies how male rat reproduction is affected by BPA as a model for humans. Studies have investigated how sperm are affected, hormonal changes during reproduction and how reactive oxygen species (ROS) affects sperm.
