Simulation of rattan harvests in Indonesia : different harvesting pressures and the resulting patterns
The objectives of this research were to determine whether the natural rattan resources in Sulawesi, Indonesia can cope with the strongly increased harvesting pressure that has occurred over the last centuries. I was furthermore looking for patterns in the rattan population dynamics that might give a hint on how the harvesting system could be improved to ensure a maximum sustainable yield. To
answer these questions, I developed an individual-based model to analyse the dynamics of rattan growth in connection with rattan harvests by locals to identify sustainable levels of rattan harvests around villages in Sulawesi, Indonesia. Scenarios with different harvesting intensities were run to compare the change in harvest amount. For a given harvesting pressure, scenarios with a high number of harvesters and a low harvesting frequency had the same effect as scenarios with high harvesting frequencies and a low number of harvesters.

Förbättrad balans hos kvinnliga innebandyspelare efter fem veckors balansträning i relation till skaderisk. : En kombinerad litteraturstudie och empirisk studie
Introduction: Balance is a complicated term which includes a static, dynamic and functional part. These parts have, during a long period of time, been included into the existing training programs through several different balance exercises, which aim to prevent sports injuries mostly focused on the knee and ankle. In floorball these injuries are common and a sports injury prevention program is required.Purpose: The purpose is to explain the balance term and relate it to injury prevention training and the existing theories. A second purpose is to see whether five weeks of balance training increases the balance ability in female floorball players and thereby increase the test values in the two tests.Method: Twenty female floorball players participated in the study and were divided into a training group and a control group. They performed a Star excursion balance test (SEBT) and a Multiple single leg hop stabilization test (MSLHST) before and after a five week training period, containing exercises of balance.Results: The training group showed improvement after the training period, however only one significant result was found.
Hur formas ett inlärningsklimat som är framgångsrikt över tid? : En observationsstudie om fotbollstränares beteenden och träningsaktiviteter
Aim and research questionsThe over-all aim of this study was to gain insight info how two male coaches of a specific soccer team behave in a practice environment with regards to educating the players.More specifically, the study sought to map the extent to which said behaviour matched two specific methods of learning; these being Teaching Games for Understanding (TgfU) and Enhanced Guided Discovery (EGD). Research questions: (1) Do the coaches employ the methods and guidelines, which are outlined in the educational plan provided by the soccer association? If so, what form does this application take in practice? (2) To what extent and in what ways do the coaches utilize feedback and questioning techniques in the education of players? (3) What similarities and differences in behaviour can be identified between the chosen soccer team?s two coaches?Method: The data for the study was collected through field observation. The subjects were two youth elite soccer coaches and observation of these coaches took place during five regular practice sessions on the soccer field. All data gathering and analysis were carried out using a modified version of the Coach Analysis and Intervention System (CAIS).
Har ökad öppenhet påverkat den automatiska stabilisatorn? : -en makroekonomisk paneldatastudie
This paper investigates the automatic stabilizer and the underlying factors behind its function. The paper includes both a literature review and an empirical analysis. The literature review discusses the IS-LM and Mundell-Fleming models and different ways to quantify the automatic stabilizer. Based on the theory, the relationship between volatility in GDP and the size of the automatic stabilizers is then analyzed with the help of regressions. Our main result shows a negative relation between these two variables.
E-handelsrelationer: en fallstudie av hur e-handelsföretag
arbetar med sina relationer till konsumenter
The purpose of this thesis is to examine how e-commerce companies work with their relationships to customers. We have conducted a case study of two companies, Koll and Webbshoppen, both active in the e-commerce industry. Our empirical study has shown that it is important for e-commerce companies to create long-term relationships to their customers, but it can be difficult to create these relationships since the companies have little contact to the users of Internet. To build relationships, e-commerce companies market themselves through different types of media to create awareness. It is also essential to be situated high in search engines.
Värdet av aktierekommendationer
This paper presents a study that evaluates the performance of stock recommendations issued on Swedish stocks during 2003. The selection of recommendations in this paper originates from banks, major brokerage firms and financial press located in Sweden. The total of 171 recommendations consisted of 99 buy recommendations and 72 sell recommendations.

A mere 50 percent of the recommendations in this revision had a weak ability to outperform their benchmark indexes as in other similar revisions.

Skötsel av ekholmar och eftersatta ekbestånd på låga boniteter : en fallstudie
This case study is made on assignment of Södra, region Öst, as a part of a campaign
promoting more active management of the oak forests in the region.
Hardwood trees of good quality, especially oak, has a high value due to that the sawn
material is highly estimated by the market. It is important that the Swedish oak forests
are managed in a proper way in order to meet the future demand. Södra has therefore
decided to increase the focus on oak in the Kalmar region and they would like to find
out if continues cover forestry (CCF) under certain conditions can be an appropriate
management model. The motive is to make use of the existing oak forests more
efficient, not just considering well managed forests but also the more neglected oak
forests, on poorer soils. Thus, the objective for this study is to examine if CCF is
appropriate method in the three stand types; broadleaved mixtures oak forest, oak islet,
and oak/spruce forest.
Existing management models were surveyed in the literature.
Produktivitetsstudie Brobyggnad
The development of productivity in the construction industry has long been at a steady state compared to the manufacturing industry. Studies have shown that, amongst other things, waste on construction sites can reach up to one third of the total production cost. This has been observed from different aspects, and change is forthcoming.This thesis aims to provide a foundation for an increased productivity at production sites of building bridges. It is primarily based on a field study at Skanska, at a bridge construction site near Grängesberg. Via continuous interviews with the whole production crew, construction workers and management, information on interference and possibilities of improvement at the work site has been documented.

Rabies : en utmaning för Indien
This literature study describes the ways in which the spread of rabies can be prevented in India, what guidelines are set and also which methods have proved most effective.
Every year rabies causes the death of around 20 000 people in India, which makes the prevalence in the country the highest in the world. The main source for human infection is bite wounds from infected dogs. People and animals can be vaccinated both prophylactic and post-exposure prophylactic (PEP), despite this the disease continues to claim high number of victims. The majority of those dying are young men and children from the poorer part of the population. Knowledge among the Indian population on rabies and its transmission routes, wound care and vaccinations is very limited.
