Antropogena aktiviteter har på ett avgörande sätt bidragit till den klimatförändring som idag anses vara vår tids största utmaning. Oroväckande sociala, ekonomiska och ekologiska konsekvenser kommer att följa om inte åtgärder på ett effektivt sätt reglerar utsläppen av växthusgaser. Då internationella förhandlingar på senare tid inte har lyckats få till stånd verkningsfulla bindande avtal, har uppmärksamhet riktats mot geoingenjörskonst. Geoingenjörskonst definieras som ”avsiktlig storskalig manipulering av jordens klimatsystem” och erbjuder således möjligheten att via olika tekniker nå snabba temporära lösningar för att kyla ner planeten. Geoingenjörskonst väcker dock fundamentala miljöetiska frågor om huruvida implementering bör ske eller inte. Syftet med studien är således att identifiera hur geoingenjörskonst framställs i den miljöetiska litteraturen, vilka argument som lyfts fram och dess potential att motverka klimatförändringen. Studiens metod utgörs av en pro et contraanalys, där sju utvalda artiklar analyseras och deras pro respektive contraargument gentemot spetsformuleringen ”geoingenjörskonst bör implementeras” lyfts fram. Argumenten diskuteras i förhållande till varandra och utifrån två valda teorier, konstruktivism och rationalism. Slutsatsen visar att geoingenjörskonst har stor potential att motverka klimatförändringen med ett stort spann av möjliga tekniker. Dock råder stor oenighet mellan miljöetikerna huruvida implementering bör ske, då starka argument både för och mot återfinns av etisk och samhällspolitisk karaktär. / Anthropogenic activities have made a decisive contribution to the climate change that today is considered to be our greatest challenge. Disturbingly social, economic and ecological consequences will follow unless steps effectively regulate greenhouse gas emissions. As the international negotiations in recent time have not managed to achieve effective binding agreements, attention has been directed towards geoengineering. Geoengineering is defined as the “deliberate large-scale manipulation of the Earth´s climate system”, and thus offers the possibility of using various techniques to achieve quick temporary solutions to cool the planet. Geoengineering does raise foundational environmental ethical questions about whether implementation should take place or not. The purpose of this study is therefore to identify how geoengineering is produced in the environmental ethical literature, the arguments that are highlighted and its potential to mitigate climate change. The study´s methodology consists of a pro et contra analysis, where seven selected articles were analyzed and their pro respective contra arguments against the lace formulation “geoengineering should be implemented” was highlighted. Arguments discussed in relation to each other and by the two selected theories, constructivism and rationalism. The conclusion shows that geoengineering has great potential to mitigate climate change with a wide range of possible techniques. However, considerable disagreements between environmental ethics are whether the implementation should take place, when strong arguments both for and against were found of ethical and socio-political character.

We investigate whether there are green returns to education, where formal education encourages pro-environmental behaviours using nationally representative surveys on environmental issues in Thailand. To establish the causal relationship between education and green behaviours, we exploit the instrumental variables strategy using the supply of state primary schooling i.e. the corresponding number of teachers per 1000 children, which varies over time and across regions as the instrument, while controlling for regional, cohort and income effects. We find that more years of schooling lead to a greater probability of taking knowledge-based environmentally-friendly actions a great deal, but not cost-saving pro-environmental actions. In addition, the paper finds no significant impact of formal education on concern about global warming nor the willingness to pay for environmental tax.

The thesis will examine in detail the cultural magazine Listy pro umění a kritiku. The author will focus on the historical context that accompanied the publication of the magazine (the situation in the former Czechoslovakia, an independent state, Nazism in Germany etc.). Emphasis will also be placed on Czech drama, especially on the avant-garde theater. The author will build on her bachelor thesis, in which she managed to get the primary material and describe it. Now she will devote the greater part of the interpretative and analyzing passages.

The infestation of foodstuffs by mites is connected to health risks and economic losses. Tyrophagus putrescentiae (Schrank, 1781) is a cosmopolitan generalist feeder that prefers foodstuffs of high-fat and high-protein content. The stored product mite T. putrescentiae is an emerging and predominant pest of dry dog food. It is an emerging source of allergens in stored products and homes. The results of this study have important implications for predictive models of stored-product mite populations in dry dog food. High-fat and -protein food accelerated T. putrescentiae population growth compared with the high-carbohydrate diet. The results increase the medical importance of the mite allergens detected in the feces. The cocktail of allergens, i.e. feces covering chitin, mite allergens and bacterial toxins, represent high risks for the mammalian immune system. The association of the mite with Bacillus cereus is to the medical importance.
