Effects of pendent phenol functional groups on secondary coordination spheres of heme like Fe-salen complexes
No full textSince the beginning of industrial revolution, burning of fossil fuels has mainly led to increase in atmospheric concentration of CO2 , a Green House Gas (GHG), from 250 ppm to 400 ppm between 1800 and 2012. One way to reduce the burning of fossil fuels and CO2 emission rate is to explore alternative carbon free fuels to meet the energy demand.This project aims at the synthesis and study of metal complexes inspired by biological models that will help better design catalysts to perform water oxidation more effectively.This poster won the Dean, Faculty of Science award (2020).

Responsibility, Uncertainty, and Threat : The Framing of the Örebro School Shooting in Swedish Public Service Media
No full textThis study examines how Sweden’s public service broadcasters SVT and SR framed the Örebro school shooting in February 2025. In the absence of clear factual-based information and an unknown motive. The study aims to understand how the event was defined through early media coverage and how the public service media broadcasters SVT & SR defined the problem in their framing of the Örebro school shooting. The empirical material for the study consists of a selection of news pieces, including written articles, radio reports and televised segments published in the days and weeks after the event. The method is a qualitative case study utilizing critical discourse analysis, with a theoretical grounding in framing theory, Hall’s encoding/decoding model and Fairclough’s Critical Discourse Analysis. Three main themes emerged from the analysis of the data set: Responsibility, Uncertainty and Threat. The findings show that responsibility was distributed unevenly across the different actors involved, uncertainty was being framed as a threat, calling for stabilization through official discourse. Lastly, threat was constructed via institutional actors, legitimizing increased security measures and policy changes. The study highlights how public service media contribute to the shaping of meaning during the earliest and most uncertain phases of a national crisis – in the absence of previous experiences, within the Swedish context.
21st-century scholarship and Wikipedia
No full textWikipedia, the world’s fifth most-used Web site, is a good illustration of the growing credibility of online resources. In his article in Ariadne earlier this year, “Wikipedia: Reflections on Use and Academic Acceptance”, Brian Whalley described the debates around accuracy and review, in the context of geology. He concluded that ‘If Wikipedia is the first port of call, as it already seems to be, for information requirement traffic, then there is a commitment to build on Open Educational Resources (OERs) of various kinds and improve their quality.’ In a similar approach to the Geological Society event that Whalley describes, Sarah Fahmy of JISC worked with Wikimedia and the British Library on a World War One (WWI) Editathon. There is a rich discourse about the way that academics relate to Wikipedia
Ondskan: en filmatiserad skildring av våld och maktstrukturer : En kvalitativ studie om hur idéer kring våld kommuniceras i moderna tv-serier.
No full textStudien undersöker vilka idéer kring våld som skildras och kommuniceras inom TV-serienOndskan. Studien har utgått i en kvalitativ innehållsanalys och som teoretiskt ramverk harsemiotik, multimodalitet samt narrativa strukturer applicerats. Studiens forskningsfrågor ärföljande:1. På vilka sätt kommunicerar TV-serien Ondskan idéer kring maktstrukturoch våld, och hur skildras detta främst genom huvudkaraktären Erik Ponti?2. Vilka berättartekniker används för att framställa våld inom ramen för TVserien Ondskan?3. På vilka sätt skapas makt mellan huvudkaraktären Erik Ponti och andrakaraktärer genom narrativa strukturer?Syftet är att undersöka idéer kring våld och maktstruktur som skildras i Ondskan. Målet är attkartlägga vilka berättartekniker och multimodala funktioner som används för att skildra våldinom TV-serien Ondskan och hur dessa vidare bidrar till kommunicering av idéer kring våldoch kan tolkas utifrån ett medie- och kommunikationsvetenskapligt perspektiv. Som resultat tolkas att våldsskildringarna görs genom olika narrativa strukturer och medhjälp av multimodala funktioner. Ur resultatet kan främst tolkas att våldsskildringen ärparadoxal. I den fiktiva världen ses våld som accepterat, medan genom tolkningsarbetet avseriens berättarröst kommuniceras våld som negativt. Våldsskildringarna görs genom olikanarrativa strukturer och med hjälp av multimodala funktioner

How Many Answers Are Enough? Optimal Number of Answers for Q&A Sites
No full textWith the proliferation of the social web, questions about information quality and optimization attract the attention of IS scholars. Question-answering (QA) sites, such as Yahoo!Answers, have the potential to produce good answers, but at the same time not all answers are good and not all QA sites are alike. When organizations design and plan for the integration of question answering services on their sites, identification of good answers and process optimization become critical. Arguing that ‘given enough answers all questions are answered successfully,’ this paper identifies the optimal number of posts that generate high quality answers. Based on content analysis of Yahoo! Answers’ informational questions (n=174) and their answers (n=1,023), the study found that seven answers per question are ‘enough’ to provide a good answer
Power Relations and Social Classes in Pengakuan Pariyem by Linus Suryadi AG: Reflection of Masculine Ideology
No full textThe study aims to explore power relations and social classes as the reflections of the masculine ideology of the author in the novel Pengakuan Pariyem by Linus Suryadi AG. The theories implemented in the study are van Dijk’s power relations and social classes theory and Connell’s masculinity theory. The study is qualitative descriptive and applies the Critical Discourse Analysis (CDA) method, used to dismantle the ideology that is produced and reproduced through the language within the novel. The research data are lingual units that indicate power relations and social classes which simultaneously reflect the notion of masculinity. The results of the study are as follows. First, Pariyem as the central character in the novel lives within a hierarchical and dualistic Javanese society. Her submission as the babu (housemaid) of a priyayi (noble) family does not only lead Pariyem to be dominated symbolically, but also legitimizes the priyayi (aristocrats) power over wong cilik (commoners). It is reinforced by the representations of the priyayis’ world views in terms of culture, aristocracy, bureaucracy, and education orientation. It shows that priyayis are culturally dominant. Secondly, since Pariyem is a character created by a male author, her behaviors and actions reflect the ideology of masculinity. Rather than voicing women, the power relations that Pariyem experiences through the events constructed in the novel show that she embodies the masculine ideology, or masculinity.

March for Science: Sign with a quote from scientists Linus Pauling, E. Pine St. at Belmont Ave., Seattle, Washington, April 22, 2017
No full textText on signs read: "No science = No hops, no malt, no water, no beer [the letters in the word beer are made up of periodic element symbols]"; "Facts are the air of scientists. Without them you can never fly. - Linus Pauling. Science, not silence".
Linus Carl Pauling was an American chemist, biochemist, peace activist, author, and educator.
PH Coll 1478. KinseyK116The Seattle March for Science occurred on April 22, 2017. This date was chosen because April 22 is also Earth Day. According to organizers, as many as 20,000 people attended the march, which began at 10 a.m. in Cal Anderson Park in the Capitol Hill neighborhood. The march culminated at the International Fountain at the Seattle Center. The March for Science in Seattle was one of more than 500 similar marches taking place across the United States. Demonstrators marched in support of “robustly funded and publicly communicated science and evidence as a pillar of human freedom and prosperity” and also called “for science that upholds the common good, and for political leaders and policymakers to enact evidence-based policies in the public interest”, according to a statement put out by march organizers. Washington Governor Jay Inslee and Seattle Mayor Ed Murray came out to show their support.Scienc
