Läkemedlet Oxazepam påverkar abborryngel : Exponering under embryonalutvecklingen ger effekter på tillväxt, överlevnad och beteende

Pharmaceuticals are environmental pollutants that are a major threat to aquatic ecosystems and very little is known about their ecological consequences. In this study growth, survival and behaviour (sociability, activity and boldness) of perch fry (Perca fluviatilis) were examined in order to study the possible effects of exposure to a benzodiazepine anxiolytic drug, Oxazepam, during embryonic development. The study tested following hypotheses: (1) perch growth is affected positively by exposure during embryonic development; (2) early perch survival is affected positively by exposure during embryonic development; and (3) boldness and activity increases while sociability decreases in perch fry exposed during embryonic development. Embryos of naturally spawned perch were exposed to water with two different concentrations of Oxazepam. The embryos were exposed during different parts (24-hour periods) of the embryonic development, because embryos may be more vulnerable at certain times during embryonic development and/or because the exposure at different times can produce different effects.

"Det onödiga flyget?" : En studie av inrikesflygets betydelse mellan Göteborg och Stockholm

The purpose of this essay is to study and compare the air traffic with the train traffic between Gothenburg ? Stockholm. The study is based on three different perspectives: travelling time, travelling cost and the Environmental effects. With those three factors included in the study, it will be more useful to determine if the unnecessary travel exist.This essay is based on quantitative information which has been gathered from the booking system of the train- and airline company?s websites.

Sustainability reporting within the food industry : a case study of regional differences in the plant-based non-dairy industry

Sustainability Reporting has emerged and transformed over the past decades as a voluntary practice by companies across industries that desire to show proof of good conduct and environmental; social; and economic responsibility. As industrial food production is one of the largest contributors to contemporary environmental problems, it might be expected that reporting within the industry would be both well established and well understood. Unfortunately, it is neither. In light of the food industry?s considerable environmental impact and the growing popularity of plant-based food as a more sustainable alternative to dairy products, this paper assesses and briefly discusses the Sustainability Reporting of two companies in the plant-based food and beverage industry. The research was designed to compare the practices of Europe-based Alpro and US-based SoDelicious, and this study has two major purposes: to describe the reporting of the case companies and to subsequently compare their practices to the other as well as to global reporting standards. The empirical study in this paper was conducted through content analysis.

Mamma och pappa har oftast inte tid

The main purpose of this essay ?Mama & Papa usually do not have time? (Mamma och pappa har oftast inte tid), is to investigate what possibilities the pupils have when they need help with their homework. I also wanted to see what the actual conditions are when they do their homework. My second purpose is to see what their teachers think about homework and what they think are the positive and negative effects of homework. To be able to answer my main purpose I made a questionnaire with the pupils.

Nyhetens behag: En kvantitativ studie av möjligheter och risker med produktplacering på modebloggar

The advantages with product placement in blogs compared to traditional media is shown in earlier empirical findings where consumers found blog posts more credible and informative than a corresponding article in a web paper. It can therefore be argued that the informal structure and personal tonality of the blog reinforces the effects of product placement on brand attitude and intention to buy as the consumer has no persuasion knowledge and does not detect the rewriting of the product as commercial.This paper?s overall aim is to provide concrete implications for how to manage product placement on fashion blogs. The purpose of the essay is therefore to investigate the communicative effects of product placement in fashion blogs as well as to examine if a revelation of commercial interest behind a blog posts about a certain brand effects the consumers? attitude towards the blog and/or brand attitude and intention to buy.

Introduction of heifers to an automatic milking system

Automatic milking systems (AMS) are part of a growing trend in Sweden and the number of milk-producing farms is decreasing rapidly. One main reason for the AMS is its ability to facilitate work for the farmer. The effects of introduction prior to calving have not been documented earlier and farmers are not in agreement, however they seldom see a problem with the introduction. The aim of this report is to find differences between two groups of heifers, where one group is trained i.e. introduced to the AMS before calving and the other group is introduced after calving.

Vilken påverkan har kvinnlig politisk representation för utfallet av klimatpolitiken? En studie av hur andelen kvinnliga ledamöter påverkar svenska kommuners utsläpp av växthusgaser

During recent decades several studies have investigated how different social roles and socialization processes between women and men affects our attitudes, values and priorities to environmental problems. Many empirical studies among the general public, indicates that women tend to show a greater environmental concern than men, because of women?s different health- safety- and risk perception. Even though the results are well established among the general public, when investigating if elected women in public offices tend to express a higher environmental concern, than do men, the results are not that clear. By using a dataset covering all the 290 municipalities in Sweden, this study aims to investigate if there is any correlation between the amount of female representatives in the municipality and the amount of emissions of CO2e per capita.

Omvärldsanalys av Sveriges ekokommuner

Miljöfrågorna och miljöarbetet har förändrats under de senaste åren och det har blivit uppenbart att något måste göras för att begränsa människans miljöpåverkan. I Rio, 1992 hölls FN:s konferens för hållbar utveckling och grunden för det internationella tänkandet om det ?uthålliga samhället? lades och gav genomslagskraft även i Sverige. Sveriges Ekokommuner är en ideell förening som jobbar för att utbyta kunskap, kompetens och erfarenheter inom ramarna för en hållbar utveckling och det uthålliga samhället..

En förtvinad opposition? : En kartläggning av hur europeiseringen och den inre marknaden påverkar det nationella partipolitiska handlingsutrymmet i fallet Vaxholm

This thesis aims to study the indirect effects of the Europeanization on national parties and the presence of an established national opposition towards the European Union (EU) and its effects in Sweden, as a result of the so-called conflict of Vaxholm. The questions asked were whether or not it existed an established national opposition towards the EU, and if so, what the opposition consists of substantially. The research method, which was used, is a quantified text analysis on the chamber debates of the Swedish Riksdag and the party congresses of Socialdemokraterna. The study shows that there is an ambivalent opposition towards the EU and its effects in the aftermath of the conflict of Vaxholm.  Socialdemokraterna presented resistance, but did not manage to present apparent alternatives, which left the party with a rather indistinctive opposition. In contrast to the right-wing party, the left-wing party had some profound difficulties in positioning itself in the new and globalized economy. I therefore suggest, that it might be more providing and exhaustive to introduce Azmanova?s ideal-type analysis, which instead of positing parties on a left-right continuum, posit parties after respective party?s opinions concerning the risks or opportunities which the EU and the internal market?s effects. .

Inuit Circumpolar Conference, en till synes avvikande NGO - En fallstudie av en ursprungsbefolknings organisering kring miljöfrågor och deras sociala och kulturella rättigheter

With ever-increasing environmental problems in the world, I have with this thesis aimed at studying how the Inuit people of the Arctic organize themselves around the issue of environmental degradation. In focus for this thesis is the organization Inuit Circumpolar Conference (ICC), an NGO that focuses on saving and protecting the social and cultural rights of the Inuit people, along with the environment in the four arctic regions. This aboriginal population has a strong connection to the environment they dwell in, as the area serves as a source of income and nutrition as well as an historically important place for their culture.I will in this thesis primarily investigate the methods of operation amongst NGOs, as well as their ability to influence and interact with the UN. These are three concepts that I, as a hypothesis, considered to distinguish ICC from other NGOs. With help from three theories about NGOs, I conclude that certain central elements of ICC differ from the average NGO, making ICC a new kind of actor in global politics..

Ny metod fo?r ma?tning av va?gkvalitet : En statistisk studie o?ver samband mellan va?gkvalitet och socioekonomisk utveckling

New method for measuring road quality- A statisticalstudy of the relationship between road quality andsocioeconomic development A new tool with implications for road maintenance has the potential to yield statistical data for road quality in a large number of regions. This thesis investigates the possibility to develop a method, from this data, for evaluating the effects of road quality on socioeconomic development.The thesis is essentially divided into two parts. Part one looks to qualitatively establish the link between socioeconomic development and road quality and the second part focuses on how to develop a method for evaluating the effects of road quality on socioeconomic development. A method was devised using categorical data and a multinomial regression model. This method provides a comprehensive overview of the complex relationship between a variety of different variables.

Effekter av fysisk aktivitet på psykisk ohälsa hos unga kvinnor

Among young adults and especially women, psychological issues are common phenomena in the society such as depression, anxiety and stress. Research has shown that physical activity can be a complement for anti-depressant medication. The aim of this review is to examine previous research to find out how physical activity can provide positive effects on overall mood state in particular young women's psychological health. The results of this review is that there are support in the literature of young women that physical activity may enhance mood in studies of depression and anxiety symptoms and small support for the effects on reducing stress. Physical activity with both high intensity and low intensity has shown to have positive effects on depression and anxiety, but the physical activity has to be regular for long-term effects.

Sverigedemokraterna - isolerade eller påverkande?

This essay examines the indirect effects of the local strength of the Swedish Democrats on refugee acceptance in the Swedish municipalities. With statistical methods this essay has aimed to investigate if such effects exist and by using statistical data from three periods of time - 2002, 2006 and 2010 ? the investigation has been able to measure effects over time. Based on former research and reasonable expectations the hypothesis for the essay claims that the Swedish Democrats has got an indirect effect upon the refugee acceptance. With the statistical analyses made, the essay is able to conclude that the strength of the Swedish Democrats in municipality elections as well as the change of this strength between the elections does have a negative effect upon refugee acceptance in the Swedish municipalities.
