Drivkrafter bakom den totala faktorproduktivitetens utveckling på regional nivå : En fallstudie på de svenska FA-regionerna under perioden 1990 ? 2005

Production requires the input of capital and labour. Hence, economic growth can be assumed to follow from increased levels of these two factors. Policies aimed at increasing production may consequently successfully be focused on facilitating the accumulation of capital and labour. However, even when an economy has managed to reach the same quantities of input factors as a more prosperous neighbour, the level of the production might still differ. The explanation of this lies in what economists refers to as expression embracing the characteristics of the input factors and the conditions in which they operate.In this thesis a calculation of total factor productivity is carried out, using existing data on the Swedish FA-regions between 1990 and 2005 and the method the economist Robert Solow in the 1950?s.

Samspel i staden : en studie av Shared Space ur landskapsarkitektens perspektiv

In East Africa live two species of Griffon Vultures; Rüppel?s Griffon Vulture (Gyps rueppellii) and African White-backed Griffon Vulture (G. africanus). One of the apparently most important factors limiting the population of these birds is food supply. Griffon vultures nest for eight months of the year, and are during this period geographically tied down to the nesting place.

Uthållig sanitet : en förstudie i staden Picota, Peru

The access to good sanitary facilities is an important factor that elevates the experienced living standard as it improves hygiene and reduces the transmission of deseases. The ratification of the millennium goals by 189 countries demonstrates that this is an important international issue. Together the countries have taken upon themselves that the proportion of the population that lacked access to sustainable safe drinking water and sanitary facilities in the year 2000 will have been reduced by half by the year 2015. In Peru, the construction of sewage pipe networks to transport the sewage out of the direct human environment is progressing. The safety and sustainability of these systems can be questioned, since in Peru the sewage seldom receive any treatment before being emitted to a recipient. This is taking place in Picota and sorrunding villages as well. In the last 25 years several systems implementing small-scale onsite treatment have been introduced throughout Latin America in an attempt to give more people access to sustainable and safe sanitary facilities, reducing water consumption and taking advantage of the agricultural values of the sewage fractions while protecting the environment from its negative impact. In this study three different sanitary systems and the effects of different population growths were compared.

Förklädnad för frihet : En performativitetstudie av Lian Hearns Blossoms and shadows

A large part of the Iranian population resented the west, in particular USA and Great Britain, during the Islamic revolution in Iran 1979. The people were also resenting the adverse effects of the trumped up frame made in Iran. The last shah of Iran, Mohammad Reza Pahlavi was detested by many in Iran for its west-oriented regime. The resentment among many Iranians is a consequence of the violations of e.g. the lack of political and civil rights, there were no existing legal security in the society, there were no economic distribution and the regime of Mohammad Reza Shah violated the human rights.The resolution from an Iranian perspective for riot is not new, during the last centuries the abomination against the despotic kings have been existing varyingly and big riots have been raised.  The Islamic revolution in 1979 was new because the revolution added adverse effects of west, the population detested west and expressed it by protesting through demonstration.  The significance of the revolution in 1979 was also attributable to Islam.

Movement patterns of Eurasian lynx (Lynx lynx) around their kills in southern Sweden

During the last ten- fifteen years the Eurasian lynx (Lynx lynx) population in southern Sweden has increased considerably. This area has a high density of both people and roads and have a higher roe deer (main prey of lynx) density than the rest of the country. Movement patterns such as how long animals utilize their kills and how far they travel from their kills between revisits is unknown for lynx in southern Sweden. The aim of this study was to examine how different factors affected the time lynx used their kills and the distances they travelled from the kill between revisits. The data was prepared and calculated using ArcGIS and the study is based on 98 ungulate kills and 12 lynx individuals.

Centrumhandel i relation till externhandel : - en fallstudie om Strängnäs

In the 90's the establishment of external trade centers had a strong growth in Sweden, primarily in large and medium cities. Gradually took smaller towns by this development. In larger cities with larger and growing customer base than in small towns were not affected by the trade centers heavily, but in the smaller towns where the customer base was smaller, there was a risk that it created a negative competitive relationship between external trade center and trade in the citycenter. In some cases, competition is a positive development for both the citycenter and external trade areas, but in some cases there was a risk that the center became impoverished. In such situation there are theories that the different variety of different types of goods should be at the center and in external trade center could lead to a balanced trade relationship.

Hur anpassar sig Gyps-gamar (Gyps rueppellii och G. africanus) i Östafrika till oregelbunden och osäker födotillgång?

In East Africa live two species of Griffon Vultures; Rüppel?s Griffon Vulture (Gyps rueppellii) and African White-backed Griffon Vulture (G. africanus). One of the apparently most important factors limiting the population of these birds is food supply. Griffon vultures nest for eight months of the year, and are during this period geographically tied down to the nesting place.

Jätteuttrar och deras beteende när de tilldelas musslor i hägn

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.

Svenska preferensaktier: Ett eget kapital- eller skuldinstrument?

On Nasdaq OMX Nordic Stockholm there has been a large increase in issues of preferred stocks since the financial crisis 2008. Aiming to explain whether preferred stocks have most of their characteristics relating to debt or equity, we answer four sub questions. Do all preferred stocks share the same features, or do they differ from each other? Our population is similar in characteristics, except for the preferred stock of Swedbank which is convertible and deviates when it comes to participation in dividends - instead of convertible the others are limited and redeemable. Further, the second sub question treats preferred stock in relation to the common stock quantitatively, in market data.

The influence of forestry stands treatments on brown bears (Ursus arctos) habitat selection in Sweden ? an option for Alberta forestry?

The brown bear population in Alberta, Canada has been decreasing, while the Swedish has been increasing and all the affecting parameters are not known. This study examined the difference in these populations to see if an explanation could be found in differences between the forest management. The aim of the paper was to see if stand treatments had an influence of brown bears habitat selection in autumn in Sweden and how the results can be used in Alberta. This was done by analyzing bear positions in Sweden with forest data, and comparing forest management data for the study area in Sweden with forest management data for Alberta. The results displayed that mature forests over 60 years that have been commercially thinned are selected by bears rather than forests over 60 years that have not been commercially thinned in.

Undernäring hos äldre personer med fokus på könsskillnader- En kvantitativ studie

Introduction: Malnutrition leads to loss of health and coexists with disease and loss of function. A good nutritional status becomes more important the older you get to maintain a good health. Studies show that it is important to identify and prevent malnutrition in its early stages. Men and women recieve different medical treatment in a number of different medical diseases. There are few studies in nursing from av gender perspective.Aim: The aim of this study is to examine the prevalence of malnutrition in the elderly in Västra Götaland with focus on gender differences when it comes to prevalence and nursing interventionsMethod: A register study with av quantitative approach is conducted to answer the aim.

Prevalensskillnad av katarakt mellan män och kvinnor i en synhjälpsökande population i Guatemala

Syftet med studien var att med hjälp av direkt oftalmoskopi undersöka om det finns någon skillnad i prevalens av katarakt mellan män och kvinnor i en population i Guatemala som sökt synhjälp. Metod: Studien genomfördes på patienter som sökt synhjälp via organisation Vision For All i Guatemala. Synskärpa och bästa korrektion utvärderades med hjälp av Snellen E-hake tavla på fem meter och provbåge och provglas. Både höger och vänster öga undersöktes med direkt oftalmoskopi på 30 cm avstånd ca 20 grader temporalt. Undersökningen utfördes odilaterat och graderades efter Mehra och Minassians studie från 1988. Totalt deltog 181 patienter varav 108 var kvinnor och 73 var män.

Porcine viruses in Uganda : a study of TTSuV and PPV4 in wild and domestic pigs

Uganda has the largest pig population in east Africa, and most of the animals are owned by smallholders. Infectious diseases among pigs have a devastating impact on the livelihood of these farmers, which are dependent on the proceeds from pig rearing. In a metagenomics study of the wild pig species bushpig (Potamochoerus larvatus), the porcine viruses Torque teno sus virus (TTSuV) 1and 2 and Porcine parvovirus 4 (PPV4) were detected. TTSuV1 and 2 are ubiquitous in the world?s swine population, and PPV4 has been found in USA and China, but neither of them has been studied in Africa previously.

Biovetare, bibliotek och bioinformatiska resurser

Bioinformatics is an interdisciplinary scientific subject which connects biology, biomedicine and information science. Bioinformatics generates new biological knowledge by using computer methods and biological databases and can thereby play an important role for the understanding of diseases and be used for development of new medicines. The appearance of bioinformatics has thereby had a big impact on biomedical research.In this study, I have examined bioscientists' use of bibliographical databases, bioinformatic databases/web sites and bioinformatic tools and their needs of support concerning these resources. I have also examined which support the scientific libraries offer their users concerning bibliographical databases, bioinformatic databases/web sites and bioinformatic tools and have compared it with the needs the libraries think that the users have and the needs the users state that they have.The results from the study show that there is a wish for library support concerning bibliographical databases, bioinformatic databases/web sites and bioinformatic tools. The wishes of the respondents are in contrast to the libraries' view about bioscientists interest concerning bioinformatic databases/web sites and bioinformatic tools.
