Bevarande av parker, trädgårdar och landskap

Abstract In order to work with historical sites, there must be an understanding of the complexity around the preservation of parks, gardens and landscapes and the approach to be used in the rebuilding and renewal. These issues are an important starting point of this essay. Historical environments give us as individuals an insight in who we are and from where we come, which is an important part of our need of identity as human beings. Without them, our roots in the past will be non-existent. The importance of this support base lies not only in the garden conservation, but also in the picture of developments, which we have through of as time mirrors of our living environment.

Det emotionella valet - ett alternativ och komplement till rationaliteten

The purpose of this thesis is to evaluate and develop a useful theory of human behavior that recognizes the importance of our emotions. The new framework, called the theory of emotional choice, is developed by a holistic method in which results from the fields of psychology, sociology and (neuro-) biology are used to mutually support the conclusions. The theory is distilled into six preliminary points, which are based on the finding that we are not thinking as logical, rational and longsighted as is often assumed. Instead the regular human thinking is suggested to be shortsighted, intuitive and ruled by our emotions and our needs for generality, causality and normality.To demonstrate the usefulness of the new framework, it is used in an analysis of financial bubbles. Additionally, the fields of negotiation, election and ethics are suggested as potentially interesting to analyze with the new theory..

Daglilja : en studie av växtslaget, handelskedjan och sortimentet

This thesis describes the genus Hemerocallis, the trading with daylily from hybridizer to seller with emphasis on the Swedish market. The first part describes the daylilies biology its botany, breeding, production, pests and diseases. Also the tobacco ringspot nepovirus recently confirmed in Sweden is described. Since the breeding of daylily is mainly done in Florida topics like hardiness and influence of the climate are included. The first part is mainly based on literature studies, but also interviews with growers and breeders from Sweden, USA, Holland and Germany.

Tr?stadens dolda utrymmen: fasader i husens mellanrum som kulturhistoriskt k?llmaterial

This thesis explores the narrow spaces between closely built houses in the over 300-year-old wooden town center of Mariestad, Sweden, and their potential as time capsules and sources of knowledge in cultural-historical building investigations. By interpreting well-preserved carpentry work on a facade in one of these spaces, the study aims to provide an example of how these preserved spaces can serve as a source of knowledge and understanding of craftsmanship and the history of the place. The thesis also addresses the municipality of Mariestad's work with cultural heritage, as well as maps out more of these potentially interesting interstitial spaces. Old Swedish wooden towns possess a high degree of uniqueness both nationally and internationally; nevertheless, they are subjected to relatively significant threats of demolitions and substantial changes, often in the form of many smaller restorations or changes over a long period of time. The focus of the case study is a window from the 16th or 17th century and the facade's old, hand planed wooden cladding.

Ekoturismens natur- och miljöpåverkan i polarområden

Tourism in the Arctic and Antarctic is increasing rapidly. In both Polar Regions, the cruise tourism is predominant. Several of the tour operators arrange trips under the banner of ecotourism, meaning that the trips should be ecologically sustainable. To ensure ecotourism standards there are different types of certifications; for cruise travels in the Arctic there is AECO (the Association of Arctic Expedition Cruise Operators) certification, and for travels to the Antarctic IAATO (the International Association of Antarctic Tour Operators). Promoters of ecotourism argue that these trips are important because they create support for conservation work among tourists making them ?polar ambassadors?.

Med hunden i fokus - en metod att identifiera hundars användningsområde utifrån det postkraniala skelettet

AbstractThis is a study of present day dogs with the purpose to establish a method to investigate archaeological dogs and determine their use in the past. The study has focused on measurements of five bone elements, scapula, humerus, radius, ulna and femur. A principal component analysis has been applied in order to decide which measurements to be further used in the analysis. Different proportions have been calculated on these measurements.A test to try the method has also been done on bones of a wolf and a dog without known background. The results from the different elements are positive, and they narrow the field down to two dog types of which one is more likely to be true than the other.The final results show that, although over lapses between the four different dog groups; hunting dogs, guard/work dogs, sled dogs and shepherd's dogs exists, it is possible to distinguish different dog usage from the proportions of the bones..

Energieffektivitet och kvalitet på inomhusluft i radon förorenade bostadshus

To build a sustainable future should we first understand that; every aspect of our daily lives can affect the environment. It?s important that we take responsibility for understanding how we impact the environment and change our actions accordingly. The worlds total energy consumption equivalent to 80 million MWh / year. This corresponds to about 220 million MWh / day.Energy consumption is one of the main reasons for increased greenhouse gases when the reduction of this consumption has a great demand worldwide.In order to prevent the energy that consumed the buildings must be energy efficient but there is a conflict between radon ventilation and energy conservation in a building, given that ventilation can consume as much energy (currently 29-59% of energy-efficient houses use), especially in a cold climate as in Norway.

Förskola med eller utan ämnesspecifika samarbetspartners.

Mitt syfte med examensarbetet är att undersöka om en samarbetspartner med speciella ämneskunskaper ger bättre förutsättningar för förskolan att kunna erbjuda förskolebarnen olika ämneskunskaper, än förskolor med förskolepedagoger. Jag valde att titta på ämnet biologi genom att göra observationer i tre olika förskolor samt intervjua två pedagoger på varje förskola. Resultatet är att förskolorna skiljer sig åt i vad de erbjuder barnen inom ämnet biologi, men om det beror på om de har samarbetspartners eller inte gå inte att fastställa av enbart den här undersökningen. Flera faktorer som förskolans miljö, vilka som jobbar på förskolan samt barnens intresse påverkar också. Men undersökningen visar att verksamheten påverkas av att ha samarbetspartners.

Kan mjölkkors utnyttjande av vallprotein bli bättre? : utfodringsstrategier och konserveringsmetoder

The purpose with this literature study was to investigate the possibilities for improvement of forage protein in dairy cows with focus on feeding strategies and conservation of forage protein. The utilization of forage protein in dairy cows is often not that efficient as it could be. The feed crude protein consists of both true proteins and non protein nitrogen. The digestion of proteins in the rumen depends on the protein degradation rate and the ability of the microbes to synthesize microbial protein. The microbes need a balance between carbohydrates that provide them with energy and proteins that are degradable in the rumen.

Sexualitet och idealbilder : Unga tjejers syn på attityder och normer kring kvinnlig sexualitet

The purpose of this thesis is to find out how young girls reason about norms and attitudes towards female sexuality. Through a qualitative research approach ten girls in grade 9 has discussed in two focus-groups on what is typically female, the ideal images of the ultimate woman as well as what is considered to be characteristic of female sexuality. The results were analyzed using Tina Mattson's theory of intersectionality, Beverly Skeggs theory of respectability and Göran Burenhults thoughts about biology and sexuality. Some of the main findings are that the girls in the study associate femininity primarily with external attributes and beauty and the ideal image of the woman is beautiful, yet independent. Further they describe different conditions for boys and girls to explore their own sexuality, and also that for girls the risk of being branded a "whore" is ever present.

??biology tells us what goals are humane?? - Ett maktperspektiv på biologismens uppfattningar kring kön, sexualitet och ?ras? i NRK:s programserie ?Hjernevask?

Den här uppsatsen syftar till att problematisera framställningar av maktordningarna;kön, sexualitet och ?ras? i NRK:s populärvetenskapliga dokumentärserie;?Hjernevask? från 2010, samt hur dessa kan förstås ur ett maktperspektiv med fokuspå poststrukturalistiska och postkoloniala teorier. Uppsatsen behandlar även vilkahegemoniska positioner som går att finna i serien. Analysen bygger på endiskursanalys av materialet som utgörs av alla sju avsnitten i programserien.Resultatet visar att programseriens betoning av de biologiska förklaringsmodellernakring kön, sexualitet och ?ras? skapar en diskurs som riskerar att upprätthålla enheteronormativ rasism som får figurera i norsk public service, samt reproducerarhegemoniska positioner som verkar uteslutande och normerande.

Liv mellan himmel och jord : Barns tankar om livet, döden och livets uppkomst

Syftet med studien är att synliggöra hur barn tänker om liv och död och deras uppfattning om livets uppkomst. Genom att utgå från ett biologiskt- och ett filosofiskt perspektiv så är mitt syfte att synliggöra barns oliktänkande i ämnet. Min valda metod till studien är semistrukturerad intervju integrerat med bildskapande med barn mellan 5-7 år. I resultatet av min studie så synliggörs barns olika sätt att förstå och uttrycka livsnära fenomen på. Resultatet visade också på barns oliktänkande genom en naturalistisk-, evolutionär- eller en skapelsekopplad beskrivning av livets och människans uppkomst.

Försvarsenhetens arkiv : Examensarbete på länsstyrelsen i Södermanlands län

The defence unit´s archive stretches over a time limit between the middle of 1971 to the end of 1987. The records the archive mainly contains are concerning the civil defence, inspection and construction of shelters, war- and crisis planning. The majority of the records are registered record, as often is the case with an authority?s archives. The main problems that occurred concerned what should or shouldn´t be public, the principle of provenance and what to prioritize; finish the project before deadline or make sure the records are prepared for a storage that ideally should last for several lifetimes..

The welfare of bottlenose dolphins and killer whales in captivity

The aim of this paper was to investigate whether or not it is possible to keep bottlenose dolphins and killer whales in captivity while maintaining good animal welfare. Today, many zoos and aquariums claim that their primary function is to conserve species and educate people about conservation and threatened species. The keeping of wild animals is justified by conservation programs and by the information spread to the zoo visitors. This does however not seem to be the case for marine mammals such as bottlenose dolphins (Tursiops sp.) and killer whales (Oricnus orca) since these species are not threatened in the wild and neither of them are listed as threatened in IUCN's Red List. Bottlenose dolphins and killer whales are entirely aquatic carnivores and are distributed in all coastal and pelagic waters from the Arctic ice in the north to the Antarctic ice in the south.

Vilka mål och behov har olika typer av skogsägare kring sitt skogsägande? :

The NIPF (Non Industrial Private Forest) owners in Sweden have very differentiated goals and needs with their forest. They have different backgrounds and some of them live at their forest estate while other live in an urban environment, and some are economically dependent on their forest estate while others are not. The heterogeneity among these forest owners creates problems for market actors that want to aim marketing messages to catch their interest. This is the problem background to the task that was provided to us as an investigative masters thesis for us. Their request was a plan for ensuring a successful marketing towards different segments of the NIPF owners. We commenced with a literature study based on market information and previously carried out similar investigations. We summarized the most important market information from the literature and created some hypotheses regarding goals and needs of the NIPF owners.
