Vad ska produkten heta? En kvantitativ studie om produktnamns påverkan på konsumenten.

The number of products offered by retailers has increased immensely during the last two decades, which has resulted in an increase of naming decisions having to be made. The importance of product names has become more significant for retailers offering their products online, as these are more visible to the customer in comparison to products offered offline. Consequently, it is of great value for retailers to gain knowledge about how a product name affects the customers' perception of the product. The purpose of this study is to examine whether product names affect customers perception of the relevant products in the online environment. This has been illustrated by applying the following theories to the relevant product names; meaningful and meaningless brand names as well as concrete and abstract words.

Utvärdering av olika metoder för framställning av höjdkurvor från laserskannade höjddata

Lantmäteriet (the Swedish mapping, cadastral and land registration authority) has been laser scanning Sweden since 2009. From the laser scanned data a digital elevation model (DEM) in grid format, with a resolution of 2 m, is produced. This DEM is called GSD-Höjddata, grid 2+ and from its data and the laser point cloud itself (in the form of a las-file) contour lines can be extracted. Lantmäteriet has not yet done this, but plans to update the contour lines in their cartographic products exist. If this is to be done in a satisfactory way an evaluation of different methods for it is needed.

Mellan äng och lund : ett trivalent programförslag för Södra Lillängen

Ian Thompson menar att man, vid gestaltning, bör ha som mål att slutresultatet ska inneha höga värden av ekologiska, sociala och estetiska kvaliteteter. Detta benämner han som trivalent design, något som han menar att generellt innebär bättre design än uni- eller bivalent design där endast en respektive två av dimensionerna ovan tas i beaktande. I detta arbete är syftet att ta fram ett programförslag för ett bostadsområde i Södra Lillängen i Mariehamn och samtidigt undersöka trivalent design som hjälpmedel för landskapsarkitekten. Frågeställningen som använts är hur ekologiska, sociala och estetiska dimensioner kan bevaras och gestaltas vid en exploatering av Södra Lillängen. Arbetet har delats upp i en förstudie och en programförslagsdel. Förstudien bestod av en inventering, en art- och habitatsundersökning och en analys. Under inventeringen studerades området och omgivningen för att ta reda på vad som fanns på och omkring platsen idag.

Överläkare i ortopedi och kirurgi : Likvärdiga arbeten med lika löner?

This investigation is a pilot survey whose main purpose is to investigate with work evaluation and attitude analysis whether the orthopedists and surgeons work can be equaled, why the wages differences exists between women and men, and also which preventive measures the organization can use to even out the wages differences between the genders. In relation with the investigation I have applied the reflexive way of thinking to establish which difficulties come up in the work of gender-equality.The result?s from work evaluation displays that the works are equivalent but the salaries are not, which can depend on value discrimination,gender discrimination and the organization theory.Wages differences between women and men depend on, according to the informers, partly by historical explanation and partly by the old directors who was allowed to retain regular salary when theypost transformed. The common point of view is that men have a larger work experience and therefore a higher salary.The managements attitude towards gender-equality issues is of absolute importance in order to achieve and bring a change within the organization.The measure positive special treatment is proposed to be used as an improving method to achieve (gender)equality between the posts and to even out the wages difference between the sexes.To establish whether or not gender discrimination exist in the investigated organization there needs to be done a whole lot supplementary studies like a complete wage (salary) mapping which includes all supplements and more interviews among the organizations all occupation groups..

Zonerat skogsbruk på fastighetsnivå ? effekter på ekonomi och miljö

Det traditionella svenska skogsbruket bygger på ett trakthyggesbruk som tillämpas på största delen av arealen. Generell hänsyn lämnas vid skogliga åtgärder i form av levande och döda träd samt orörda områden. Utöver detta lämnas hela bestånd och nyckelbiotoper. Denna modell har fått kritik för att den skapar ett fragmenterat och variationsfattigt landskap med dåliga förutsättningar för många skogslevande arter att reproducera och sprida sig. Ett alternativ är triadskogsbruk där arealen delas upp i zoner med olika mål.

Två rödlistade arter i ett fragmenterat landskap : en studie av konnektivitet

Sedan trakthyggesbrukets införande har stora förändringar skett i de svenska skogarna. Viktiga negativa effekter av trakthyggesbruk på skogslevande arter är habitatförluster och habitatfragmentering. I detta sammanhang är begreppet konnektivitet viktigt. Konnektivitet beskriver i vilken utsträckning arter kan röra sig mellan lämpliga habitatfläckar i landskapet. Konnektiviteten för en art är beroende av andel lämpliga habitat och artens spridningsförmåga. Konnektivitet undersöktes för tolvtandad barkborre och lappmes vid olika spridningsavstånd.

Kastanjemalen Cameraria ohridella : livscykel och utbredning i Sverige 2006

Cameraria ohridella, the chest-nut leaf miner, is a new pest in Sweden. These moths make leaf mines on chest-nut trees, preferably on Aesculus hippocastanum, which results in brown blotches on the foliage and early loss of leaves. Since the first observation in Macedonia in 1985 it has spread rapidly through Europe. The moth arrived in Sweden in 2003 when it was observed in Malmö and surrounding areas. In this paper a literature study describes the morphology and life cycle of the chest-nut leaf miner. Further more a test with pheromone traps examining the number of generations in Sweden is shown.

LIDAR-analys av flygsanddyner i Västerbottens inland : Har dynmorfologi bildad under tidigare interstadialer bevarats i landskapet?

The aim of this study was to map the prevalence of aeolian sand dunes in Västerbotten, northern Sweden to find dunes formed during earlier deglaciation phases, which was then preserved in cold-based conditions during the youngest stadial of the Weichselian glaciation. These preserved dunes were expected to be covered by a layer of till and have a rather faint morphology compared to dunes formed during the Holocene. Consequently, high resolution LIDAR-derived images from the Swedish mapping, cadastral and land registration authority (Lantmäteriet) was used to detect the dunes throughout an area covering most of Västerbotten, above the highest coastline and below the mountain range. The analysis resulted in several new findings of aeolian dunes compared to the findings in the quaternary soil map created by the Geological Survey of Sweden. Despite the fact some of the dunes at the LIDAR-derived image had a strange faint appearance, it was quickly evident during the fieldwork that the aeolian sand was not covered by till on any of the dunes visited.

Information ochmaterialflödesförbättrings analys

This examination work is performed at the institution of industrial economy and production at Jonkoping technical university, for JELD-WEN Door Solutions plant in Forserum.Today the focus in the company is on to reduce their inventories binding of capitals as well as inventory of products and that includes to get a good control of the supply and handling of material which is of great importance.JELD-WEN Door Solutions is one of the worlds leading producers of windows and doors and the head-office is located in Oregon, USA.A great number of wooden doors are manufactured by the company in varying of constructions, classifications and performance.The production of the plant in Forserum has a project- and customer focus manufacturing where only internal doors are produced. The overall market they are concentrated on is to different institution such as schools, hospitals etc.The purpose of this work is to investigate possibilities to improvement of material- and production control at JELD-WEN. The report will handle the master production schedule to and from the production divisions within manufacturing industry. Focus will be on the way for information- and material flows from arrival, transport within the company and further on to customers.Further a map of the flow was performed which gave a clearer picture of the connection between the flow of information- and material for the manufacturing process. On the basis of the mapping of the flow, the group discovered that the flow of material had some improvement potential.

Planering för hållbar landsbygd

This is my final thesis in landscapeplaning at the Swedish University ofAgricultural Sciences (SLU). I discuss howthe countryside should be planned, witha sustainable perspective. In the study Iexamine four important conditions forplanning.The countryside is often defined bywhat it is not which makes it difficult todescribe in general terms. The definition ofthe term countryside in this study is takenfrom the National Rural DevelopmentAgency (Glesbygdsverket). The conclusionis: Planners and scientists should have anunderstanding for the complexity of thecountryside; otherwise there is a risk oflosing the characteristics of the country.The legislation, goals and conventionswhich have an impact on the Swedishcountryside are both national and international.To find out how the settlementdevelopment is dealt with, I havestudied the Swedish building legislations(among others, plan- och bygglagen andmiljöbalken).Similar to the difficulties on finding asuitable definition for the term countryside,it is complex to define the term sustainabledevelopment.

Förstudie till våtmark i Rimbo : Design för optimal hydrologi och kväverening

The euthropthication of the Baltic Sea is a threat that is beginning to be taken seriously by the governments concerned. In Sweden, regulations concerning the allowed nitrogen (N) concentration in the effluent water from wastewater treatment plants are being tightened up. The Rimbo wastewater treatment plant has been imposed to reduce the annual mean concentration of total N in the effluent water to levels below 15 mg l-1. A more and more common way to reduce the nitrogen level in wastewater is to let the water pass through a wetland. This study investigates the possibility to build this kind of wetland at the outlet of the Rimbo wastewater treatment plant.A prestudy of the topography, soil characteristics and groundwater flow indicates that the land area in question is well suited for the construction of a wetland.

Populationsdifferentiering hos kransalger

Kransalger är en viktig nyckelart i Östersjön. De förökar sig med hjälp av oosporer och denna studie har syftat till att urskilja morfologisk differentiering mellan oosporer inom och mellan individer och populationer. Främst ställde jag mig frågan huruvida skillnader och likheter i morfologi kan associeras med skillnader mellan olika geografiska avstånd och habitat samt i vilken mån oosporer kan återföras till korrekt population och individ. Kransalger av arten Chara aspera har insamlats på lokaler i östra Svealand och elliptiska Fouriertransformationer har använts för att med hjälp av vågfunktioner beskriva oosporernas konturer. Parametrarna i vågfunktioner har sedan använts för statistiska analyser.

Kan markfuktighetskartor användas för att hitta skogsmark med hög bonitet? : ett gis-baserat försök med dtw-index och laserskannad övre höjd

The depth-to-water-index (DTW-index) is derived from digital elevation models (DEM) to map soil wetness, in terms of distance from soil surface to the ground water table. The aim of this GIS based study was to investigate the existence of a relationship between DTW-index and forest site productivity (SP). The belief of such an assumed relationship was based on knowledge that the ground water level is related to site properties that can either promote or impede tree growth. Data primarily comprised rasters of the Krycklan catchment in northern Sweden and depicted DTW-index and a laser scanned vegetation height. The 100th height percentile of each pixel in the vegetation raster was assumed to mirror the top-height, letting it act as a relative measure of SP within a delineated area of equal stand age.

Gullrisbock (Phytoecia nigricornis) i grus- och sandtäkter i Halland.

This dissertation is done as a preparatory step for the action plan of environmental protection shall issue to preserve the Phytoecia nigricornis in the country when it is red-listed and classified as vulnerable (VU). My task was to investigate the prevalence of the Phytoecia nigricornis in Halland County. They wanted to see if it existed in Halland (Ehnström, 1999). If it did not exist they wanted to know how to improve its habitat.the Phytoecia nigricornis is difficult to inventory because when it is larvae it lives in the roots and lower parts of the trunk of the Solidago Virgaurea plant and the adult beetles only keeps to Solidago Virgaurea by mating and egg laying and larval caterpillars when they hatch (Bily, 1989; Molander, 1999). Often it is overlooked or missed, and one question was whether it existed  in the whole country or only in those parts where it was previously found in, Skåne, Blekinge and Östergötland (Ehnström, 1999).One problem for the Phytoecia nigricornis is that their habitats is declining.

Identifiering av konfliktbestånd med hjälp av laserskanning

The interest in harvesting wood fuel in conflict stands has grown in recent years as a consequence of the increased demand for biofuel. Conflict stands are young forests that have not been cleaned and have a large number of stems ha-1with a great height and diameter distribution. This means that traditional field measurements in conflict stands are difficult and very time consuming. Therefore, the forestry sector is in need of new, more efficient inventory methods. In this study, the Lidar data from Lantmäteriet?s (the Swedish mapping, cadastral and land registration authorities) new national height model was used in combination with plots from the Swedish national forest inventory from 2009 to create functions for; height, volume, diameter and number of stems.
