Local stakeholders? willingness to conduct actions enhancing a local population of Grey Partridge on Gotland ? an exploratory interview study
The population of Grey Partridge is decreasing worldwide as a result of anthropogenic activities. Increased agricultural production, requiring homogenous farming landscapes and increased use of pesticides are believed to be the main factor causing population declines in the Grey Partridge. Actions to enhance Grey Partridge populations are available; however, those actions are vain if the acceptance to conduct them is low. To gather information about acceptance among farmers, hunters and the County Administrative Board towards 18 available actions enhancing the Grey Partridge population, nine face-to face interviews were conducted as an exploratory case study. The results showed that willingness to conduct enhancing actions differ between and within the groups of stakeholders.
Fåglar i urbana miljöer : kvaliteten på urbana habitat och om beståndstäthet är ett bra mått på habitatkvalitet
The urbanization of the world is increasing. How it affects bird populations have been well studied during the last decade, and comparisons between urban and non-urban habitats have been carried out. A common method for measuring habitat quality is to calculate the population density. This method is easy to use, but have been criticized during the last couple of years. In this study, data of population densities was compared with data on reproduction success.
Ekonomistyrning i små tillväxtföretag : En studie över sambanden mellan tillväxt och ekonomistyrning
Tillväxt och ekonomistyrning förstärker varandra simultant då en växande företagsstorlek har en positiv inverkan på utvecklingen av ekonomistyrning. Samtidigt möjliggör en välanpassad ekonomistyrning en fortsatt hög tillväxttakt via dess förmåga att hantera tillväxthämmande faktorer. Utvecklingen av ekonomistyrning påverkas av en kombination av interna och externa drivare..
Marknadens riskpremie ex-ante på Stockholmsbörsen
Resultaten visar på att abnormal earnings model är en mertillförlitlig modell i förhållande till dividend growth model. Dettafrämst då abnormal earnings model grundar sig på mer tillgängliginformation samt att tillväxträntan i dividend growth model harkonstaterats vara orealistiskt hög. Analytikers prognoser tenderaratt vara optimistiska i början av undersökningsperioden 2000-2002. Perioden 2003-2007 präglas mer av pessimistiskavinstprognoser. Marknadens riskpremie fluktuerar mindre underperioden 2005-2007, vilket kan förklaras utav införandet av IFRSår 2005..

Tillväxt hos Husmossa (Hylocomium splendens) i boreal skog och växthus : effekter av ökad vattentillgång
Hylocomium splendens (Glittering wood-moss) is a common species in the Nordic countries and can be found in many different types of boreal forests. It usually forms dense moss carpets on the forest floor. The shoots grow in segments and new segments form annually on the previous years growth. The size of the segments is probably regulated in a high extent by local micro environmental conditions. Previous experiments suggest increased growth of H.
Skogstillväxten ca 20 år efter plantering på Flakmossen : dikningens och gödslingens betydelse vid beskogning på en avslutad torvtäkt i Värmland
This study was performed in an afforestation experiment established 1982 on an abandoned peat harvesting area, Flakmossen, in the province of Värmland, SW Sweden. The experimen-tal design include planting with Scots pine (Pinus sylvestris), in combination with various drainage intensities (20, 30, and 40 m between ditches), and fertilizer doses 0, 100, and 200 g PK per seedling applied at the date of planting.
The aim of this study was to achieve more knowledge about the conditions on afforestation of peat harvesting areas, especially regarding drainage intensity and fertilization requirements, by means of determining the stand growth and yield in the Flakmossen trial.
The forest growth did not differ significantly between the drainage intensities tested when the same amount of phosphor and potassium fertilizer was added. Thus, shorter distances between ditches than 40 m can not be recommended.
When no fertilization was carried out seedling survival was very low, and the growth of sur-vived seedlings was poor. The largest diameter and height growth were observed in the areas where the highest dose of phosphorus and potassium (200g/seedling) was given.
Beståndsutveckling i stormskadade granbestånd
The storm Gudrun in 2005 led to massive windthow damage in forests in southern Sweden.
Since then there has been a growing interest in factors influencing wind damage in above all
Norway spruce (Picea Abies) stands. Although many other interesting areas still need to be
examined. In 2005 there where a lot of stands that suffered different degrees of damage, a lot of
these stands weren?t cut, but instead left to grow. The future development of these stands is
uncertain and the guidelines are unclear.
Occurence of mould and mycotoxins in Swedish maize silage - a pilot study
During the last ten years the cultivation of maize in Sweden has increased and is expected to grow further. Most of the maize in Sweden becomes silage which is used to feed animals at farms. Maize has in other countries been shown to be a substrate for growth of mould and especially Aspergillus spp., Fusarium spp. and Pencillium spp. has been reported.

An attempt as to whether Corporate Social Responsibility has an impact on growth companies is demonstrated. Volkswagen Group is within the required analytical criteria, which are to be studied. Also, the fact that they recently launched ?Strategy 2018? makes it even more interesting to immerse into.
Implied Dividends and Equity Returns
This paper studies the option market?s implied dividend as a predictor of future equity market returns. We introduce this variable in the simple total return framework and discuss some complications of using it as a proxy for the expected dividend. We construct some regressions using the price-dividend ratio and the implied dividend growth, and test them on six years worth of data on the EURO STOXX 50-index. The main result is that implied dividend growth exhibits some forecastability over two-year horizons, but that the dataset is too short to draw any definitive conclusions about long-horizon forecastability.

Individuell tillväxt och substratval hos en lokalt differentierad population av Asellus aquaticus
Local differentiation may occur during a short period of time and is part of the formation of new species. The isopod Asellus aquaticus is an example of a species in which local adaptation has occurred during a short period of time. An establishment of stonewort (Chara spp.) vegetation in Lake Tåkern (in the 2000) resulted in two different Asellus ecotypes; a lighter pigmented, smaller one that lives among stoneworts grazing periphytic algae, and a darker, larger ecotype that feeds on decaying leaves in reed (Phragmites australis vegetation. The purpose of this study was to examine whether there are differences in growth between ecotypes, depending on whether the food was periphytic algae or leaves, and to study the choice of substrates between the two food types. For the study, animals from both habitats were brought in from Lake Tåkern to the laboratory.
Informal settlements : the world's invisible communities
Since the beginning of the new millennium the world?s population has increased exponentially fast. The majority of this growth has been accommodated for by urbanization of the developing world. This in turn has lead to a wide spread of informal settlements. Thus, areas of urban slums, that have risen illegally on the marginal lands within and at the periphery of the formal city.
