Det relativt nya fenomenet reality-serier blir allt populärare och upptar en stor del av dagens tv-tablå. Fenomenet tillsammans med övrig massmedia har större inflytande och påverkan på samhället och oss människor än någonsin tidigare. Man diskuterar alkoholens roll i samhället, dess konsekvenser för relationer, hälsa o.s.v. Sedan TV kom har även alkoholens representation i TV kommit att bli en he
Titel: Du sköna nya konsument - En kvalitativ studie om hur konsumenter resonerar kring virtuella recensioner. Datum för seminarium: 2016-06-02 Kurs: FEKH29, Kandidatuppsats i marknadsföring, 15HP Författare: Filip Dahlin, Marit Joten och Nils Nordström. Handledare: Clara Gustafsson Syfte: Syftet är att skapa en förståelse för hur konsumenter resonerar kring virtuella recensioner. Uppsatsen s
Although previous researches have covered various kinds of identity studies, the identity issues particularly among the Chinese immigrants to Sweden remain poorly understood. Therefore, this thesis contributes to the vast amount of research by focusing on how and why the Chinese immigrants’ identities have developed after immigration. Based on nationalism and national identity theories in modern C
Bakgrund: Höga ljudnivåer och bullerskador är ett vanligt problem på arbetsplatser. Många väljer att inte använda hörselskydd då de upplevs försvåra kommunikation. En metod som med ett enkelt mått kan utvärdera hörselskydds påverkan av taluppfattning vore värdefullt. Syfte: Syftet med studien var att undersöka möjligheten att med metoden Speech intelligibility impact Level (SiimpL) mäta skillnad m
Access to a quiet side in one's dwelling is thought to compensate for higher noise levels at the most exposed façade. It has also been indicated that noise from combined traffic sources causes more noise annoyance than equal average levels from either road traffic or railway noise separately.
Neonicotinoids, systemic insecticides that are distributed into all plant tissues and protect against pests, have become a common part of crop production, but can unintentionally also affect non-target organisms, including pollinators. Such effects can be direct effects from insecticide exposure, but neonicotinoids can affect plant physiology, and effects could therefore also be indirectly mediate
Fatty acid biomarkers have emerged as a useful tool to quantify biomass of various microbial groups. Here we focus on the frequent use of the fatty acid 16:1ω5 as a biomarker for arbuscular mycorrhizal (AM) fungi in soils. We highlight some issues with current applications of this method and use several examples from the literature to show that the phospholipid fatty acid (PLFA) 16:1ω5 can occur i
Green infrastructure (GI) is increasingly used in policymaking to promote biodiversity and enhance ecosystem services through the protection, creation, restoration and connection of natural and man-made green areas. The EU Commission adopted in 2013, the concept as a strategy. When member states apply the policy, it is translated into specific bureaucratic and political systems, creating different
We have investigated the bacterial decomposition of dissolved organic matter (DOM) extracted from the organic layer of a boreal forest soil and filtered at a pore size of 0.2 µm. This DOM source has previously been extensively characterized and contains approximately equal amounts by carbon of a colloidal fraction, mainly composed of carbohydrates, and a fraction of molecularly dissolved DOM. Here
Context: Land-use intensification to increase yields is often detrimental to biodiversity undermining the provision of ecosystem services. However, it is questionable if ecosystem service providers contribute to ecological intensification by achieving the same or higher yields than conventional high-intensity agriculture. Objectives: In this study, we aimed to disentangle the effects of local and
Human activities in deciduous forests over the past centuries have influenced associated species. To reduce extinction risks and mitigate population declines, there is growing interest in forest conservation and restoration, including initiatives by the European Union (EU). For resulting restoration and conservation practices to succeed, it is essential to know which forest characteristics promote
Pollinators are estimated to benefit the reproduction of three-quarters of global leading crop species and contribute to 3%–8% of the total global food production. Ongoing declines in pollinator populations have raised concerns about repercussions for food security. Thus, there is a need to better understand how agricultural yields depend on pollinator abundance. Here, we established yield–pollina
In the pursuit of more sustainable agriculture, weeds play a dual role by threatening crop production and simultaneously contributing to farmland biodiversity. Management actions such as the use of fertilisers (fertilisation) may change weed abundance and community composition with consequences for both weed–crop competition and biodiversity. Alleviating the balance between yield and biodiversity
Organismal abundance tends to decline with increasing body size. Metabolic theory links this size structure with energy use and productivity, postulating a size–abundance slope of −0.75 that is invariant across environments. We tested the robustness of this relationship across gradients of protist species richness (1–6 species), temperature (15°C–25°C) and time. Using replicated microcosms, we pro
Insect pollinators are declining globally, partly due to agricultural intensification, which threatens biodiversity and ecosystem services. To help decision-makers make informed choices, a variety of tools such as softwares, websites and frameworks have been developed to guide pollinator-friendly management and conservation. However, the lack of a comprehensive overview of these tools limits stake
Land use change threatens global biodiversity and compromises ecosystem functions, including pollination and food production. Reduced taxonomic α-diversity is often reported under land use change, yet the impacts could be different at larger spatial scales (i.e., γ-diversity), either due to reduced β-diversity amplifying diversity loss or increased β-diversity dampening diversity loss. Additionall
Anthropogenic land-use and climate change pose novel selection pressures on bees, yet their evolutionary responses in terms of morphological or physiological adaptations remain unclear. While adaptive responses are expected, these may be constrained by gene flow when changes in selection pressures are spatially heterogeneous. The buff-tailed bumblebee (Bombus terrestris) is a widespread species th
Residential gardens can provide pollinator habitat and thus contribute to mitigating declines of insect pollinators. To further improve gardens for pollinators, it is necessary to understand the factors and pathways leading to successful conservation interventions. We studied how the success of two common pro-pollinator interventions, garden meadows and flower plantings, were influenced by gardene
Tudo o que comemos gera impactos ambientais: do uso do solo na lavoura, passando pelo transporte, processamento, consumo e descarte de embalagens e resíduos. Entender esse impacto ambiental da alimentação é complexo, mas já existem informações suficientes para orientar decisões mais bem informadas.
