När förmänniskan blev den moderna människan

The subject of this bachelor-level thesis in archaeology in the transition from archaic sapiens to anatomically modern humans, and what might have caused this transition. A part of the study aims to prove or disprove whether an increased consumption of shellfish might have caused this development. Another part of the essay deals with the connection of said evolution and the suggested emergence of cultural and ritual practices in South Africa circa 100 000 BP and an evaluation of the arguments concerning the aquatic ape hypothesis, and their usefulness for the subject.The result of investigation of the theory about the increased consumption of marine resources as a probable cause of the last biological step of creating our species points to the conclusion that it is a probable explanation. There is even some evidence that there could be a connection between consumption of marine resources and the "Out of Africa 2"-theory. It is harder to find a proven connection between the suggested emergence of cultural and ritual practices, even some evidence seems to strengthen the idea.

Efficient treatment of adolescents with behavioural problems

The purpose of this essay is to investigate which components previous scientific studies suggest that an efficient treatment for adolescents with behavioural problems should contain. For this purpose, an extensive review of scientific research conducted in Scandinavia has been read and will be presented in this essay. This essay also present an introduction to residential care in Sweden as well as to an alternative form of treatment for adolescents with behavioural problems called Multidimensional Treatment Foster Care (MTFC). The result of this essay suggest that treatment of adolescents with behavioural problems should be based on the emphasis of risk/resilience factors of the youth and that the treatment should be adapted to the youth?s individual personality and way of learning.

Kinetikens tecken: en experimentell studie i samspelet mellan kroppens rörelser och dess försvarsmekanismer

Relationships between defence mechanisms and body movements were investigated in regard to three hypothesis; I. that a difference in frequency of body movements correlates to different signs of defence mechanisms, II. that themes of body movements can be identified in regard to signs of defence mechanisms, III. that no significant differences will be found between the different groups of gender. The aim of the study was to seek a relation between quasicommunicative body movements and defence mechanisms.

Risk och osäkerhet vid inträde på den svenska apoteksmarknaden: En studie om nya aktörer på en marknad under omreglering

The Swedish pharmacy market will be re-regulated in July 2009 which will present private actors with an opportunity to enter the market. Several risks and uncertainties are associated with such an entry. The purpose of this thesis is to increase the understanding of identification and management of risks and uncertainties associated with entering the Swedish pharmacy market. We also intend to investigate similarities and differences in risk identification and risk management as well as create an understanding of the underlying reasons for these similarities and differences. Three companies interested in entering the market have been interviewed and the interviews were conducted with an open approach to avoid influencing the companies? answers.

Combined with official reports and the new legislation, an analysis is formed.

Generationsskräpsamling med explicit kontroll av hårdvarucache

This report evaluates whether an interpreted high-level garbage collected language has enough information about its memory behaviour to make better cache decisions than modern general CPU hardware.With a generational garbage collector, depending on promotion algorithm and generation size, around 90% of all objects never leave the first generation. This report is based on the hypothesis that, because of the low promotion rate, accesses to higher generations are sufficiently rare not to benefit from caching.To test this hypothesis, we built an operating system with a Scheme interpreter in kernel mode, where the interpreter controls the cache. Generic x86 PC hardware was used, since it allows fine-grained control of cache decisions.Measurements of execution time in this interpreter show that disabling the cache for generations higher than the first does not give any performance gain, but rather a performance loss of up to 50%.We conclude that this interpreter design is not an improvement, but cannot conclude that the hypothesis is false in general. We suggest building a better CPU simulator to gather more data from which to make better caching decisions, moving internal interpreter data structures into the garbage collected heap and modifying the hardware to allow control in the currently rigid dimension of where data is cached---for example separate control of instruction and data caches and separate data caches for different areas of memory..

Inkomstfördelning och ekonomisk utveckling -en studie av forna sovjetstater

The economic development and industrialization that has taken place in many parts of the world during the past century has brought about a huge increase in economic welfare. During this process, it has repeatedly been debated whether the gains from economic development are shared by everyone or just a few. In the field of economics, vast research has been conducted on this particular subject ever since the 1950?s. The most famous contribution might be said to be Simon Kuznets article, Growth and Income Inequality from 1955 and the ?inverted U?-hypothesis that was formulated on the basis of that article.

Värmebehandlat trä ? att inhämta synpunkter i produktutvecklingens tidiga fas :

This study is a part of a Swedish research and development project that is about heat-treated wood and is led by the Swedish University of Agricultural Sciences and Luleå University of Technology. Products that are heat-treated already exists on the market, foremost the Finnish brand ThermoWood®, bur the project group want to find out if it would be possible to start a Swedish production with somewhat different applications than what is common today. The heat-treated wood has many attributes that have changed in the heating process. It becomes more biologically durable, it gains stability in form and dimensions and it becomes darker and looses several unwanted extractives such as resin. Disadvantages that can be mentioned are that the wood becomes fragile and the strength properties changes. My main purpose with this study is to look into customer involvement in the early phase of product development. I also want to find out if the customers I interview think that the product is worth working with, which means start a Swedish production.

Ägarstrukturens påverkan på tillämpningen av Svensk kod för bolagsstyrning: En studie av bolagsstyrningsrapporter

In the light of some company scandals the Swedish Code of Corporate Governance, the Code, was introduced in the year of 2004 to reinforce confidence in how Swedish listed companies are managed. As many of the other European codes of corporate governance, the Swedish Code is based on the principle of ?comply or explain?. The need for corporate governance regulation arises from the inherent conflict of interest between owners and managers. This conflict is limited in companies controlled by a family in contrast to companies that lack a strong owner.

ENERGIANVÄNDING PÅ BYGGARBETSPLATSER : Analys av införandet av energieffektiva bygg­etableringar

This report is the final step in the Bachelor of Science program in Building Construction Engineering, Department of Engineering Sciences, Uppsala University.The purpose of this study is to highlight the difficulties and possibilities that could involve the introduction of new energy efficient technologies and changing work around this technology. This study focuses on energy use at a construction site or other temporary workplace where so-called portacabins are in place to address the need for temporary facilities.The method for obtaining knowledge on the subject was mainly interviews with site managers working in Svevia AB's various activities. In conjunction with the interviews I visited construction sites and portacabins if it was possible.My most important suggestion to Svevia AB concerns a better organization in order to make poratacabins more efficient on energy and costs. The company should also evaluate and monitor the energy efficient portacabins that are in operation.Expected energy savings of new technology may not materialize if there are gaps in information, education, technical services and technical maintenance. It is very important to utilize the experiences of new technology.
