Gynnar eller motverkar kommunerna kostnadseffektiv miljöstyrning : en studie av kommunala taxor och avgifter

Local charges may induce people to change their pattern of consumption by influencing investments and acts in certain directions. Some charges could for example give people incentives to use less natural resources. This study investigates four different local charges and whether they benefit an economical management with natural resources or not. This is carried out by investigating whether there is a polarity between local charges that may influence environmental actions or goods, and effective pollution control set to achieve certain nationally determined environmental goals. The study includes two economic perspectives and investigates on the one hand whether local charges counteract governmental subsidies and on the other hand whether the charges vary between the different municipalities since large differences may lead to cost inefficiency.

Bakteriereduktion i diskmaskiner : Studie av olika metoder för att reducera bakterier

Bacteria are a problem that occurs naturally in dishwashers when the dish stands there dirty for an extended period of time. To get rid of the unpleasant smell that the bacteria is causing, the most common solution is to run a regular washingcycle which can cause problems for the environmentally-conscious consumers since this causes unnecessary energy waste and emissions of chemicals in the washwater. To solve the problem in a more environmentally-friendly way by directly attacking the bacteria with an appropriate bacterialreductionmethod can therefore be an attractive feature in a dishwasher. There are many different ways to treat surfaces that have been exposed to the bacteria. Some high-profile methods are UV-radiation, microwaves and oxidant (ozone) that all three have had success in reducing bacteria in different contexts.

Butiksdemonstrationens mentala och beteendemässiga påverkan: - Ett fältexperiment som undersöker butiksdemonstrationens möjligheter att påverka konsumenten i butiksmiljön

The knowledge development regarding in-store marketing has shown that influencing a consumer in a store setting is a powerful tool to change the consumer?s buying patterns. However, the store as a marketing channel lacks, in many ways, conducted academic research and according to marketing theory investments into in-store marketing tend to be taken without advanced marketing consideration. As a consequence, we have chosen to generate new insights into the field of in-store marketing by studying in-store demonstrations both from a behavioral and a mental dimension. Furthermore, we have also chosen to study how different consumers with different degree of loyalty and buying patterns are influenced by an in-store demonstration.This study aimed to obtain a better understanding of in-store demonstrations through breaking down the demonstration into its core elements and from these elements construct different types of demonstrations.

Antagonism och konflikt i förskolans utvärderingsuppdrag : En diskursteoretisk studie om utvärdering av förskolans verksamhet och förskollärarens positionering i relation till detta uppdrag

The aim of this study was to investigate how the position of the preschool teacher could come across in interviews with six teachers about their assignment to document and evaluate the preschool activity. The research done so far in this area shows that it can be a complex and difficult part of the preschool teachers work. A dilemma often described is how the teachers can be able to analyze and document the children´s learning with the aim to evaluate and develop the preschool activity without judging and mapping the children. A special focus of the study was to see how the methods and dsicourses described by the teachers possibly could affect the teachers´s position in the area of documentation and evaluation. To analyze the empirical data Ernesto Laclau (1935-2014) & Chantal Mouffe´s discourse theory was used, a prespective witch also figured to be the theoretical foundation of the master thesis.

Kulturarv, efterfrågan och musikalisk mångfald En fallstudie kring bibliotekariers och användares uppfattningar om musikbibliotekets uppdrag och roll

The main purpose with this Master's thesis has been to through a case study investigate and analyze the music library activity at the Public Library in Lund, in order to find out according to which ideas and principals this activity is run by. It also discusses how you at the music department handle your task as intermediary of music and how well this coincides with the users expectations. To give the research more depth a special analysis has been made, assuming the perspective of the B&I-researcher Sanna Taljas' three perspectives regarding the music department. She identifies three perspectives in maintaining a music library, which she calls the general education, alternative and demand repertoire.The examination is based on an empirical research, where five librarians were interviewed and fifty users have responded to a survey, but the essay also includes a literary study carried out to explore which ideas there are regarding the music department's missions and roles in the existing literature.Librarians and the user's opinions coincide quite well. What distinguish the most are the opinions surrounding the competency of the music library.

Pedagogisk intervention vid audiologisk rehabilitering med hjälp av en textbok. En randomiserad kontrollerad studie.

Hearing is considered to be the most important sense for the communication between people. Several studies have shown that hearing loss can lead to deterioration in quality of life, reduced social activities, feelings of alienation and hence the increasing incidence of depression symptoms.An early audiological rehabilitation is a prerequisite for proper communication among people with hearing loss. Knowledge has been shown to be of great importance and structured learning and individually targeted approach can be expected to facilitate the audiological rehabilitation.The purpose of this study was to examine the effect of an educational effort for people with hearing loss where the effort was made in the distance within the audiological rehabilitation and was followed-up by professional phone support, through a randomized controlled study.The study group consisted of 69 hearing aid users who were randomized by an independent person into two groups, an intervention group and a control group. The intervention group (n = 33) had access to the book "When the sounds are weaker - on hearing and hearing aids". The group received weekly topic-based information related to the different chapters of the book, in five rounds.

Eskilstuna municipalityowns one of these, the other two is privately built and owned and the municipality rents time in thehalls.IF Guif and HK Eskil are two handballclubs in the central part of Eskilstuna.

Textil fotokatalytisk vattenreningsreaktor: Optimering av beredningsparametrar för titandioxidbeläggning på polyestersubstrat ämnad för vattenrening

I denna kandidatuppsats avlägsnas organiska föroreningar från vatten genom användning av textilier, vars yta belagts med nanopartiklar utav ämnet titandioxid. När titandioxid belyses med UV-strålning sker en fotokatalytisk reaktion, vilket i sin tur bryter ned bland annat bakterier och organiska färgämnen. I hopp om att finna ultimat vidhäftning mot textil passande titandioxid har olika typer av beläggningar studerats; akrylbaserade, sol-gel och slutligen en hybrid. Dessutom har fem olika konstruktioner av textila bindningar jämförts i syfte att undersöka dess påverkan på den fotokatalytiska effekten. Förorenade vatten är ett stort problem, både i utvecklingsländer och i industriella sammanhang.

Hur byggnadsdetaljer ändrar fasadens uttryck

An energy study has been performed on two blocks in an area called Gävle Strand. The buildings are owned by a tenant-owner?s association called brf Carolina and were built by the company Skanska 2008. The builder as well as brf Carolina are pussled by the fact that electricity use is higher than expected while heating is less. Skanska is also very interested in finding out how much heat recovery from stale exhaust air through a geo-thermal heat pump is contributing to the general heating requirement and energy balance in four out of the ten buildings located on the properties.To find possible answers to the higher electricity use a literature survey on user behaviour was conducted.

Bloggen ? ett redskap för byggande av identitet och sociala nätverk: En kvalitativ studie av bibliotekariers bloggande

Weblogs, or blogs, are frequently modified web pages with a series of archived entries, generally in reverse chronological sequence. This thesis focuses on the rapid-growing phenomenon of weblogs and the fact that individuals with a background in library and information science are frequent users of weblogs. Since this is an explorative inductive study the ultimate purpose can be described as to find out what ?blogging? as activity is about. The research questions posed are: Why do individuals with a background in library and information science use weblogs? How does their professional identity affect their blogging? And finally; how do they use the weblog to create networks with other bloggers? The empirical material consists of audiotaped interviews with five informants who are all employed in knowledge work, either as librarians or information specialists.

Djup icke vändande bearbetning i sockerbetsodling :

A field experiment was carried out in 2006 to investigate the effects of deep rotary cultivation on sugarbeet growth. The background to the experiment was a 2005 study showing potentially higher yield, higher cleanness and higher sugar content when primary tillage was carried out to 35 cm depth with a rotary cultivator. On four field sites in Skåne (L:a Isie, Ädelholm, Stävie and Vragerup), five different treatments were compared: mouldboard ploughing in the autumn to 20 cm; mouldboard ploughing in the autumn to 20 cm + rotary cultivation in the spring to 35 cm; rotary cultivation in the autumn to 35 cm; rotary cultivation in the spring to 35 cm; and mouldboard ploughing in the spring to 20 cm. The rotary cultivator used in the treatments is manufactured by a Dutch company, Imants. The implement cultivates the soil with spade tines fitted on arms that are mounted on a horizontal rotating PTO-driven axle. Beet plants were inspected and yield determined in the experiment, and three soil parameters were examined: penetration resistance, water infiltration and infiltration of blue dye. Root shape was also examined. The site at Stävie was not harvested due to poor beet establishment. At the other sites, the highest yield was found when the soil was rotary-cultivated in the autumn.

Falu gruva och hållbar utveckling

AbstractFalu Copper Mine and Sustainable DevelopmentKarl-Markus AnsnaesFalu copper mine was Sweden?s oldest mine industry which lasted for almost a thousand years. Throughout the history its area has been vastly contaminated by sulfur oxide. The contaminations has created the mining area to an environmental risk zone which has the ability to spread out into the Falu River. The river has its connections to the Dal River which is discharging towards its mouth in the Baltic Sea.

Gränsåtgärder mot varumärkesförfalskade varor

Infringement of intellectual property rights often causes significant economic damage. The problem with illegal activity concerning counterfeiting is constantly increasing. The development has lead to constitute an extensive international activity which is harmful for intellectual propery owners, consumers and the society in general. Competing products tend to be increasingly similar to each other, with rather similar marketing-, sales-, and pricingstrategies. As a result, the trademark strongly affects consumers? selection-process during purchase.

Värdering av kvävet i organiska gödselmedel :

Within agriculture it is important to optimize the use of nitrogen, not only from an economic point of view but also to minimize damage to the environment. This can sometimes be difficult, especially within organic farming. Organic farmers are using increasing amounts of waste products from the food industry to cover their nitrogen needs. These different organic fertilizers release nitrogen at different rates and under specific soil conditions. Because of this, it would be beneficial to have a standardized method to measure the amount and rate of nitrogen mineralization from organic fertilizers. This project contributes to this knowledge by investigating whether relatively simple and repeatable laboratory methods can be used to estimate the nitrogen fertilizer value of organic fertilizers.
