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).

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
Valuation of a Non-Performing Loan Portfolio
No full textThis master’s thesis focuses on valuation of a non performing loans portfolio, provided
by partner company Dignisia. Two models are developed; a combined classificationregression
model and a Markov chain model. Valuation performances are decent but
explanatory power, i.e. R2 values, are lower or on par with similar research.
The two models are tested in two scenarios with the aim of investigating improvement
in model performance with knowledge of prior payment history. No clear
relation is found between demographic and errand-specific attributes and debt collection
rate. The Markov chain model shows similar performance as the more conventional
method static pool, in portfolio valuation. However, advantages of the
Markov model are the adaptation to new data and the possibility of model extensions
which are further discussed. Data quality and quantity are presumed to be
the major limiting factors, which is in line with conclusions in the literature
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

No full textDrug development is today controlled by investing in projects or drugs that are believed
to provide a big return on investment. The entire process of finding a potential drug until
it is possibly sold on the market involves a variety of tests and controls resulting in huge
expenses. The vast majority of drug projects undergoing this process do not meet the
high demands set on new drugs and is therefore discontinued. This subsequently results
in a loss for the pharmaceutical company in that project. It is against this background
that Captario has developed a cloud-based tool, Captario SUM. In Captario SUM, an
user is able to construct a mathematical model over their pharmaceutical project and
simulate the outcome to obtain a forecast of profitability and other interesting aspects
of the project.
In this report we investigate the impact variations in the variables, of such a model,
have on the forecast that is obtained. We have chosen to focus only on the forecast of
net present value which is a measure of profitability. To our help, we use methods in the
field emph sensitivity analysis which have been implemented on a prototypical model
of a pharmaceutical project. A secondary goal during the project has been to try to
find suitable methods that Captario in the future will be able to integrate with the tool
and further offer their customers a sensitivity analysis on their models.
After this investigation we found various sensitivity analysis methods that are well
suitable for Captarios tool. All methods identified that the recruitment rate for one of
the larger studies was the variable that had the greatest impact for profitability. Furthermore,
this report can be seen as a first step in the analysis of drug development
models and it is discussed how one could proceed with a deeper analysis
