Hur bedrivs miljöarbete? : En undersökning om pedagogers miljöarbete i förskolan och barns tankar om miljöarbete.
By conducting qualitative interviews five pedagogues and eight children in the ages three to five have answered questions regarding environmental work in preschool.The purpose of this report was to examine how environmental work is pursued at two preschools and what children at these preschools think about environmental work. Recycling of garbage and small cultivation projects together with the children is what the pedagogues consider being the most common environmental work at their particular preschools. In the professional role of the pedagogue if can be clearly seen what special interests he or she has.Most of the children associate the forest with some kind of snack and animals. Half of the interviewed children also think about animals when they visit the forest. Half of the interviewed children also have an understanding of where peels from fruits should be tossed, but no one knows the meaning of the word environment.
Effekt av karbonatisering med biogas på aska från trädbränslen
It is essential to reuse- and recycles residues to decrease the amount of deposit materials and reach sustainable energy use. Two ways to work towards this is to recycle wood ashes to the forest as nutrient compensation and extract biogas from combustion of biomass.The aim with this study was to decide whether wood ashes that been used for biogas upgrading with accelerated carbonation also can be used as a nutrient compensation in the woods according to recommendations from the Swedish Forest Agency (Skogsstyrelsen).The ashes that were used in this study came from Johan Andersson who works at JTI in Uppsala, who also treated the ashes with biogas. The ashes have, in both untreated and treated condition, been analyzed in this study according to contents of elements, leaching properties, hardening properties and contents of crystalline phases, to evaluate what impact carbonation with biogas has on the ashes.The accelerated carbonation led to hardening of the ash, and decreased amount of CaO- and increased amount of CaCO3. The CO2-uptake also entails a dilution of the elements, and the content of nutrients and trace elements decreases. However the results show an indication of an uptake of S from the biogas to the ash, since the dilution had a smaller impact on S than the rest of the elements.
Indelning av trakter inför gallring på Holmen Skog : en utvärdering av svårigheter och möjligheter
A common goal in practical forest management is to maximize the yield, measured in economical terms. When a forest stand is thinned a so called inoptimality loss can arise due to non-optimal decisions. This means that the selected management schedule results in a lower net present value than the optimal one which lowers the profitability for the forest owner. Holmen Skog uses the term tract which means an aggregation of stands made before a management action. A tract should be delineated in different tract parts in connection with pre-thinning planning if there is different bearing capacity within the tract, different thinning grades should be used or if the tract contains a weaker part that should not be thinned.
Trädslagsinverkan på markvegetationens utveckling i odlingsförsök med tall och contorta :
In the 1970?s it was predicted that in the beginning of the 21st century there would be a timber shortage in Sweden and a large scale introduction of the exotic tree species lodgepole pine started. An introduction of a foreign tree species means a risk of a negative influence on the forests ecosystem. Today, the stands that were established in the 70?s are middle-aged and the effect on the forest floor vegetation can be studied.
Viltets inverkan på vegetationsutvecklingen i en Sydsvensk skogsföryngring :
Herbivore impact on the Swedish forest has under a long time been a common subject of
debate. There are many different opinions depending on what direction the forest owner has with his/her forest. Populations of moose and roe deer have increased significantly in Sweden during the last decades. The purpose of this study is to get a full picture of the herbivore impact on the regeneration areas. The field work was done once a year for seven years (1999?2005).
Streamingtjänster av film och dess framtida utveckling som substitut för illegal nedladdning : Konsumenternas syn på digitala tjänster och de förbättringar som krävs för ett hållbart paradigmskifte
In this paper we aim to delve deeper into the film industry and how their approach to streaming services such as Netflix might be the solution to the problems with piracy (people downloading illegally instead of paying for the products) - but before they can change the mindset of people, they have to overcome some issues that might make it hard for the film industry to adapt a fully functionable streaming sollution in the veins of Spotify. To come up with some conclusions regarding this matter, we focused our study on the consumers rather than the industry in order to get a better understanding about what the consumers think about the streaming services of film that are offered today. We used both surveys and interviews in order to gather information regarding the consumers thoughts on how the landscape of film distribution has evolved to a point where Video-on-Demand offers the opportunity to watch movies and TV-series whereever and whenever they want. Our research shows that the majority of consumers are willing to pay for streaming services of film and hold the new technology in high regard. However, the concensus among the consumers that were involved in our study shows that the streaming services offered today have to evolve even further in the future before it can fully work as a substitute for illegal downloading.
"Varumärket är ingenting utan personalen" : Intern kommunikation av varumärket inom hotellsektorn
The purpose of this paper is to examine the correlation between hotels, their brands and the frontline staff within the industry. A competitive, international environment characterizes today´s hotel industry where brands are one of the strongest sources for a successful position amongst competitors. In the brand delivery, the front line staff is of utmost importance since they in many ways incorporate the brand values and the projected identity of the hotel. Hotels can use a variety of ways to communicate the brands identity to the front line staff in order to create the desired brand behavior, some more effective than others. At the same time the Swedish hotel industry, as many other, is characterized by a high percentage of staff turnovers.
En värld i brand : - En pressundersökning om vad som skrevs om krisen i Polen 1939 och Norge 1940 i två svenska dagstidningar
Background and aim: Media development and digitalization has expanded the PR industry's working area. More participants are on the media market and it is becoming more and more difficult to define what PR really is and what the PR agencies/departments really do. Is PR marketing, information, event marketing or maybe propaganda? We believe that the complexity to define the term PR can lead to a loss of critical approach to the business, especially among young people. Has the PR industry managed to eliminate their negative image among students in upper secondary school and what do they associate with PR today? The aim of this essay is to examine what a selection of students associate with the term PR and if they are critical to the PR industry or not.Method/Material: The method is a quantitative survey.
A quantitative analysis of global kiwifruit trade
New Zealand is currently the third largest global producer of kiwifruit and thus plays an important role in the international market. Exports of kiwifruit are also of significant horticultural value for New Zealand and in 2007 the kiwifruit industry accounted for export values of NZ$790 million.
The global kiwifruit market has experienced substantial changes in recent years and is likely to change significantly in the near future due to developments in production sources, adjustments to trade policy settings and shifts in consumer preferences. The New Zealand kiwifruit industry needs to consider what the impacts of these changes might be so that future strategies can be constructed effectively.
Little quantitative modelling has been done in New Zealand to consider the impacts of changes to the global kiwifruit industry. The major contribution of this research was the development and calibration of a kiwifruit industry-specific partial equilibrium trade model. The model was then used to examine the impacts on New Zealand producers of these trade-related changes in the global kiwifruit market.
Sustainable Construction in the Transportation Infrastructure Industry? as a vision and in practice
This study has been conducted on behalf of Vectura Consulting AB with the purpose to examine how different actors perceive the dimensions of sustainability and sustainable construction. The purpose is also to provide an understanding of existing barriers and opportunities for sustainable construction within the industry and exemplify with different directions for the actors in order to develop sustainability. The study has approach the research problem by using systems theory, developed by Checkland, to identify the relevant system. Other systems theories has been used as an theoretical framework in order to identify barriers and opportunities, which in this study are based on Hughes?s theory about reverse salients and salients.
Kaliumgödsling på torvmark - effekt på tillväxten hos planterade granar (Picea abies)
Peat lands are a great potential resource for increased forest growth in Sweden, there are approximately 6.5 million hectares of peat lands, whereof around 70% produce less wood than one m3sk/ha and year and are therefore classed as forest waste land. There are over 200 000 hectares of peat land that is already drained and wooded, and that may be suitable for fertilization. Forest production on peat soils usually requires drainage and fertilization. Dewatering requires ditching the area, so that the roots can have access to oxygen. Nitrogen is often abundant in the peat but other nutrients; especially potassium is in short supply. The purpose of this work was to examine the effects of potassium fertilization on the growth of spruces that were planted on drained peat land and how different amount of fertilizers affects the growth. Potassium deficiency is strongly growth inhibiting, since potassium is important for substance transport in the tree. Potassium is also important for the carbohydrate formation, and because increasing the sugar content of the cells constitutes a lower freezing temperature does potassium availability in the soil play a major role in the winter resistance of many species. Potassium is not found in any organic compounds in the tree, but is present in cell and tissue fluids. A fertilization trial was started in 1978 in Siljansfors Experimental Forest. The plots in the experiment were fertilized with different amounts of potassium and one plot was left without fertilization. All plots that were fertilized with potassium grew considerably better than the unfertilized plot. The difference in production between the unfertilized plot and the plot that received the most potassium was 7.2 m3sk/ha and year. The unfertilized plot can still be classified as waste land. The theoretical production capacity was estimated using a Swedish system for site quality estimation of wetlands after ditching (dikningsbonitering). The plot with most potassium produced after fertilizationaproximately in level with theoretical estimations. Key words: Peat land, Fertilization, Ditching, Growth, site quality..
Har antalet naturvärdesträd i Sverige förändrats mellan 1999-2009?
Forestry and forest products are vital components of the Swedish economy but the forest is also important for recreation, hunting, out-door life and conserving biodiversity. The Swedish Forest Act has two equally important objectives, production and environmental protection. Polytax is the Swedish Forest Agency´s inventory programme which monitors progress toward the two objectives in connection with regeneration fellings. It includes data on environmental protection measures taken in connection with regeneration fellings. 30 § of the Swedish Forestry Act and related regulations specify the demands for conserva-tion of nature.
Slam ? en outnyttjad resurs i skogsbruket
Every year about 210 000 tones dry weight of sewage sludge is produced in Sweden. Most of the sludge is applied to agricultural land, plantsoil and landfill cover. Sewage sludge contains essential nutrients such as nitrogen and phosphorus. Nitrogen is limiting growth on solid ground in Sweden and can therefore be used as fertilizer to increase productivity. In order that the sludge can be spread to forest land it requires first a conversion of sludge to pellets, to make it more manageable.
Landskapsplanering och konnektivitetsförbättringar inom värdetrakter i Västerbottens län :
According to the Swedish strategy for forest protection, additionally 40 000 ha productive forestland will be protected in the county of Västerbotten, between 1999 and 2010. A national project was carried out to distinguish the proportion of forest with a high biological value, in all counties. The project resulted in demarcation of small landscape areas or small ?biological value regions? (bvr), with higher concentrations of forests with conservation values and red listed species than the surroundings. In Västerbotten, 26 such bvr?s were identified and the Counties Agency and Forest Agency in Västerbotten developed a regional strategy for forest conservation to standardize the forest protection process.
Revisionsbranschens relation till massmedia - En studie om hur revisionsbranschen påverkas av massmedias rapportering
Background: Media has for a long time been reporting about the audit industry, often focusing on so-called auditing scandals. Economic journalism has grown stronger, the corporations are given more and more power in society and the public interest is increasing. We intend to examine how mass media affects the expectations gap and how the auditing firms operate strengthening the society?s confidence in the industry after mass medial exploitation. We also want to investigate whether the relatively new phenomenon social media is affecting the auditing firms and industry?s external communication, as well as what consequences negative publicity may have for the individual auditor.Aim: The aim of the study is to create an understanding of the audit industry?s relation to the media as well as to describe and analyze how mass media?s coverage is affecting the audit industry, auditing firms as well as the individual auditor.
