Humankapital i redovisningen : En studie av kunskapsintensiva företag

Annual reports are by many considered to be companies primary way to inform their world where the CEO's words are read most carefully by shareholders. The purpose of this paper is to examine the design of the CEO's words in annual reports in light of the financial crisis in 2008. The study seeking explanations for change, similarities and differences in the various texts based on three themes which are results, future and confidence. In this qualitative study five CEO's words are explored by means of a discourse analysis, all from large Swedish industrial companies listed on the Stockholm Stock Exchange. Some of the results shown is that the CEO tends to talk about the company's results in a self-serving manner and CEO speaks more aboutm the results before than after the crisis.

Flickors och pojkars användning av adjektiv i berättande texter utifrån ett genusperspektiv.

The purpose of this study was to examine six girls and boys in grade 4 use of adjectives in narrative texts and examine students' perception and experience of writing from a gender perspective. The methods used were text analysis and an interview. The results showed that girls write more adjectives than boys, but no further significant difference in their use of adjectives was found. There was a certain stereotypical difference in which adjectives they wrote and their attitudes toward writing. Girls are more positive to writing and see writing primarily important for school, while boys think writing is important to succeed in life..

 En jämförelsestudie av koldioxidsläpp för en byggnad med trä- respektive betongstomme ur ett livscykelperspektiv

The goal with this examination thesis is to investigate the difference in carbon dioxide emissions between a building with a wooden versus concrete carcassing from a life cycle perspective. The huge amounts of carbon dioxide released into air from human activities must be reduced to prevent serious consequences. A way to limit this issue is through performing a comparative study where the result shows which of two products with the same function has the lowest emission of carbon dioxide, whereof the product with the lowest carbon dioxide pollution can be chosen.To be able to perform a study like this an object has been chosen and studies about life cycle analyses have been done. The rental square meter, the thermal conductivity value, the energy requirements and the placement of the building has been set equal in both framework types. There were solely dissimilarities of the two buildings taken into account when this comparison study was performed.The result of the study is that a building constructed with a wooden carcassing has the lowest amount of carbon dioxide emissions.

Long-term Storage of Starch Potato and its Effect on Starch Yield

Lyckeby Starch AB is a farmer-owned company that produces products based on potato starch. In order to increase their production efficiency and their international competitiveness the company is investigating the possibilities of keeping their factories open longer. To achieve this, potato has to be stored for a longer period of time than what is practiced today. Starch potato is usually stored in large piles covered by straw and plastic, either in the field or on the farmyard. The objective was to examine in what way starch yield (starch content*tuber weight) in three different potato varieties was affected by storage in two different types of storage piles. The potato was stored for three months in total and starch content and tuber weight were controlled throughout the period. Stored tubers were also visually examined and prescense of mechanical damage as well as wet rots and dry rots was recorded. Bacteria and fungi were isolated and identified. In general, varietal differences were greater than differences between the storage piles.

Samspel mellan IT-avdelningen och affärsverksamheten : En studie av attityder

IT has become more evident in most organisations and has grown to be a part of the infrastructure rather than a tool for competitiveness. Therefore focus should now lie on how IT is adjusted to the business rather than on the usage of IT. To make the best use of IT in the business the CIO needs to start think more business-oriented instead of as before, technology-oriented. To develop the IT-department in that direction the IT-staff need to start cooperate with the business and gain knowledge about stakeholders, markets and the way of working for other staff members in the business.With this as a basis, the purpose of this thesis is to investigate attitudes regarding cooperation between the IT-department and the business and if there is any difference if the CIO has business related background or not.To fulfil the purpose a quantitative investigation with the help of surveys was conducted. The sample consisted of 18 companies with 100-200 employees in the area of Jönköping.

Research on the power of customer involvement, and in particular recommendation is very resourceful. Many studies have mapped the reasons for why customers are willing to recommend, however they often ignore potential differences among brands and how that may affect these reasons. This study is built on a quantitative survey investigating how consumers interact with brands, depending on category affiliation. The categories used were Bhat and Reddy's symbolic and functional, consisting of three brands respectively where each brand represented a different product type.The evolvement of social media has also transformed the platform of recommendation from physical to virtual and changed the way people connect. Thus, taking the investigation further, potential differences between symbolic and functional brands was tested in different social media platforms.

"Alla lika olika" : En diskursanalys av mångkulturalism i den svenska arbetsmarknadspolitiken

The aim of this paper is to study how multiculturalism is expressed in the Swedish labour market policy. The method used for the investigation is a discourse analysis which study social and political processes in the society as created through language. The perspective of the discourse analysis is a social construction that considers that language is a social production created in a discursive way. It produces and reflects social process in the language.By using theories of national identity and multiculturalism we aim to investigate how multiculturalism is expressed in the labour market policy. With this method we aim to analyze the discourse of a political report made 2008 by the current government about integration strategies in Sweden.

Sänkt restaurangmoms       : Hur många jobb skapades?

År 2012 sänktes momsen på restaurang- och cateringverksamhet från 25 % till 12 %.Huvudsyftet med denna sänkning var att öka sysselsättningen i restaurangbranschen.Liknande momssänkningar har tidigare gjort på flera håll i övriga Europa. Denna studies syfteär att utvärdera om denna momssänkning har ökat sysselsättningen och så fall i hur stor grad.För att skatta denna effekt har en difference-in-difference modell använts. Studien kommerfram till att det troligtvis har skett en ökning av sysselsättningen i restaurangbranschen menhar svårt att vissa precis hur stor denna ökning har varit..

Val av tidpunkt för markberedning vid naturlig föryngring under skärm av Pinus sylvestris i Svealand : Timing of scarification when using natural regeneration in seed tree stands of Pinus sylvestris in Central Sweden

This thesis is built on a field study that was carried out in two seed-tree stands near by Götbrunna in Uppland, Sweden. The aim was to examine if scarification carried out in spring time could generate a more dense seedling establishment when using natural generation, than scarification carried out in autumn. It was also investigated whether there were differences in mortality the first season between the two plot-types. Plots were established block-wise with 50 blocks (pairs) on each site. The spring scarification was made with a hoe during 22-23 of April.

Naturhänsyn vid föryngringsavverkningar : En jämförelse mellan certifierade och o-certifierade hyggen

A growing number of Swedish forest owners are choosing to certify their forestry. However, there appears to be a lack of field surveys which describe differences between certified and non-certified forests concerning the degree of completed environmental considerations. In order to know to what extent certified forests contribute towards improved environmental consideration, we need studies on how large the difference is in relation to non-certified forests.Differences between certified and non-certified forest clearings were quantified through an inventory of the number of retention trees, dead trees and snags. The result showed that the retained number of the investigated parameters varied greatly between individual clearings, regardless of certification status. However, the results suggested that the certified clearings had an average higher incidence ofthe investigated parameters.

Höjdförändringar på Lomonosovfonna, Svalbard, 1996-2012

The climate changes and the global warming have a great impact on the Arctic environments. This partially depends on that the albedo is getting lower when snow and ice is melting and exposes more and more dark surfaces of the land and sea. This leads to a feedback effect; the melting accelerates because dark surfaces attract more sun radiation. Because of the heating the glaciers in Arctic retreat. The purpose of this report is to obtain an eventual change in elevation on the glacier Lomonosovfonna that is located on Svalbard by comparing elevation data collected by NASA and GPS data from 1996-2012.

Restoring biodiversity in degraded secondary rain forest in Sabah, Malaysia : natural regeneration of trees after restoration treatments

Many tropical rain forests has been lost or degraded as a result of human activities and environmental factors. Since the level of biodiversity is high in the tropics, maintaining these areas is of great importance. Forests like these are often assumed to benefit from forest restoration and rehabilitation. The INIKEA project area in Eastern Sabah, Malaysian Borneo, aims to improve biodiversity and/or species richness in the degraded forest through enrichment planting with indigenous species. The objective of this thesis was to evaluate how different treatments (liberation, gap-cluster planting and line planting) affect the biodiversity of natural regeneration in different forest types in the Rain forest Restoration Experiment, located in the INIKEA project area.

Anställningsotrygghetens effekt på självskattad hälsa, i hög respektive lågkonjunktur

The subject of this study was to research whether or not the effect of job insecurity on self reported health differs between good and bad times in the economic climate. Two different years of a national health survey from the Swedish institute of health (FHI) served as data, with 2007 representing good economic climate and 2009 doing the opposite. Both years consisted of data from a national health survey distributed to 20 000 random individuals in Sweden, where 2007 had 5738 valid cases and 2009 had 10 373. A quantitative method was used to determine the difference, consisting of a three variable cross tabulation with chi2-analysis as well as a model of binary logistic regression for each of the two years.The cross tabulation found a significant difference between the two years, with those reporting job insecurity having less of a chance to report bad health during the year representing bad economic climate. While the logistic regression showed the same tendency, the two years could not be significantly differed from each other in that part of the analyzes.With this in mind, the conclusion from the whole test was that no significant difference could be found between the years regarding the health effect of job insecurity..
