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.

In order to get a better understanding of the interaction between employees and their technical work tools one needs to know what factors influence the interaction. The purpose of this study was to examine if there is a correlation between the personality traits Extraversion (E) and Neuroticism (N), tested with Eysenck Personality Inventory (EPI), and experience of the new Intranet among employees at The Swedish National Transport Administration (SNTA), and also to gather information of employees? opinions about the new Intranet. A survey, containing questions about the Intranet and a personality test (EPI), was posted on SNTA?s Intranet for eight workdays (N = 88, females = 53, males = 35).

The sandy beaches of Vänern are threatened by overgrowth and thereby the biodiversity is at high risk to decline. This study is based on an inventory of vegetation of overgrowth character and mosses. The frequency and spread of mosses is perceived as an indication of initial or present overgrowth. External factors that have been taken into consideration are wind-, wave- and ice erosion, the slope of the beach, wear and grade of exposure. The purpose of the investigation is to control the beaches grade of overgrowth and find out which external factor is of most importance for the maintenance of the biotope. The results show that the beaches environment is affected by the slope of the beach, grade of exposure, size, wear and overgrowth.

The Convention on Biological Diversity (CBD) promotes the Ecosystem Approach (EA). In this thesis it is analyzed how the EA approach could be applied to regional management of coastal areas in Sweden. The aim of this report is to compare management for preserving biodiversity on a landscape level in two regional coastal areas in Uppsala and Västra Götaland respectively. In Uppsala, one of the plans consists of a previous nature reserve and in Västra Götaland, a Regional landscape strategy has been established. The ecosystem approach is used as a theoretical framework in this thesis.

Familjestrukturer och föräldraroller är i förändring. Stereotyper av föräldraskap har bidragit till rådande attityder där män och kvinnor i icke traditionella familjestrukturer bedöms mindre fördelaktigt (Brescoll & Uhlmann, 2005). Studiens syfte var att se om attityder påverkas av huruvida föräldern är karriärist eller föräldraledig samt man eller kvinna. En pilotstudie genomfördes för att generera egenskaper för föräldraskap och bestod av 30 deltagare. I huvudstudien deltog 115 personer, varav 69 kvinnor och 46 män.

The thesis investigates if it is possible to replace several pumpimpellers with one controllable pumpimpeller, with a economical and a manufacturing analisys aspect. The studied pumpimpeller is mounted on a midrange wastewaterpump, N3127MT.In the thesis a contemplated manufacturing process is evaluated for a concept that are supposed to act as a controllable pumpimpeller. The pumpimpeller are studied in a manufacturing and flow matter and are presented in the thesis.The manufacturing cost is also estimated, and this has been compared to the storage cost and other costs that the existing pumpimpeller generates.The thesis also shows that the concept has minor losses in cutting quality aswell as the effiency comparing to the existing pumpimpeller.The concept also raises the manufacturing cost and this increasing cost makes the presented concept to expensive to carry through.An investigation of the costs that the existing pumpimpeller produces has also been done, and this shows that there is not that much expenses to earn regarding to for example the storage cost. The storage cost includes information from Flygt?s central storagecenter in Lindas, Sweden and Metz, France, and also an inventory about the pumpimpellers located at Flygt?s different distributors worldwide.The thesis shows that a controllable pumpimpeller will generally increase the cost for the pumpimpeller and the performance of the pumpimpeller will decrease..

Abstract This essay will present actual research around the concept of Post- Traumatic Stress Disorder, how it can reveal itself in school children and how it can influence young people?s learning ability and capacity to retain knowledge.The purpose is, above all, to clearly diagnose PTSD so that children with this complex of problems can receive good possibilities in learning and understanding.The question at hand is responded to by interviewees with an expertise on the subject and one ?story?, collectively with literary studies.The results illustrate that there can be neurological and biological, as well as social explanations for PTSD but it is seldom a permanent diagnosis. It is though something to take very seriously. PTSD can lead to severe psychobiological consequences, mostly by causing damage in one particular part of the brain, known as hippocampus. The hippocampus is essential in terms of memory and concentration.

Den sociala kontexten inom idrotten är en viktig orsak till utövares motivation. Sociala skäl såsom känsla av tillhörighet, att vara del av ett lag och social status rapporteras som centrala anledningar till engagemang. Syftet med denna studie är att undersöka vilka motiv individer anger till sitt motionerande med fokus på de sociala aspekterna, med en jämförelse mellan könen. Studien utgår ifrån Deci och Ryans Self-Determination Theory (2000). Motiv till deltagande i motion mättes genom användandet av ?The Exercise Motivation Inventory-2?.

The number of sawmills in Sweden has decreased dramatically since the 1980s and the trend looks set to continue. The sawmills that are left instead becomes larger and are situated farther apart. In northern Sweden, they are concentrated along the coastline.In our study, we compared conditions for running a sawmill in inland areas and coastal areas and looked at what factors have the greatest impact on the profitability of the sawmill in northern Sweden.We chose to compare different locals conditions for a sawmill that only sawn pine timber and had an annual raw material requirements of 300 000 m3ub per year. By analyzing the kNN-data from the Swedish National Forest Inventory we have taken out the size of the timber volume at each site and its catchment. We have also looked at possible competitors in the areas that may affect the purchase price of the commodity.

According to FSC (Forest Stewardship Council) shall at least a mean of 10 trees per hectare including riparian zones and other areas with high biological values be left in final felling. In addition large clear areas should not be created and all retained trees with high environmental value shall be spared. To leave trees in final felling means a lower cutting volume and hence a lower income from the cutting, but it also means that the production in the next generation becomes less because of competition. The aim of this study was to evaluate the effect retained trees have on the production in the new generation of forest, and to investigate if there is any way to lower this effect. The environmental care has also been estimated by the amount left in final felling.

The purpose of this thesis was to investigate how an industrial company can increase customer value by offering added services to their core products. Theses added services can be categorized into the three different parts of the buying process. The company that was investigated is Smurfit Kappa Kraftliner in Piteå, a large international industrial company active on a business to business market. We have conducted a case study and made interviews with three respondents within the company. The result of the study show that the company offers value added services in each stage of the buying process.

Over the past thirty years the political parties in Sweden have lost five out of six members. In order to retain existing members leadership in these organizations has become increasingly important. The aim of this paper is to identify what group leaders for party groups within the municipal council believe are the driving forces that underlie the councillors' voluntary commitment, identify the group leaders' leadership style and identify whether there exist a relationship between these driving forces and the leadership style. The approach applied is qualitative consisting of twelve interviews with twelve group leaders from six different municipalities in Stockholm county. The theoretical framework of this paper includes the Volunteer Functions Inventory and the Full Range Leadership Theory.

This master?s thesis investigates how six Swedish public libraries integrate equality aspects in their user oriented activity. The theoretical starting point for the study is that Sweden is a part of a gender system characterized by gender separation and male superiority, as described by the Swedish historian Yvonne Hirdman and theories that argue that femininity and masculinity are social constructions. Another starting point is that the library sphere cannot be separated from the gender inequality in society. Since the library is part of a gender system that value individuals who are seen as males and separates men and women, some of the library users may be neglected.

AbstractAbetong in Falkenberg manufactures, among other things, small prefabricated concrete buildings for housing various installations, such as electric transformers.The aim of this dissertation is to reduce the time needed to design such buildings, by way of finding a number of standardized buildings. Standardized in such a manner as to incorporate both the needs of the manufacturer (Abetong) and its customers.To analyze the needs of the parties the work has included a market survey and calculations on the strength of these buildings.One survey was a letter questionnaire to all of Abetong?s customers who have, in the past, ordered these types of building. The aim of the questionnaire was to establish how the customers want these buildings designed.Another survey conducted was an inventory of all of Abetong?s previous projects where these types of building were manufactured.

ABSTRACTThe discussions about energy use have increased year by year everywhere in the society, and so also in the healthcare sector. But what is actually energy use in a hospital facility, and what affects it?The typical way today to express the energy use is in kWh/m2. The problem with a key performance indicator that is expressed as energy use in relation to a specific area is that it does not take into account the activity in the building. Even though the activity to a very high extent affects the energy use.
