Fishing for Function: Identifying Functional Binding Partners of CUG-Binding Protein 1
No full textAdditional contributors: Bernd Rattenbacher; Paul Bohjanen (faculty mentor).One of the most remarkable distinguishing features of living organisms is their
ability to fluidly adapt to changing environmental conditions. The advances in molecular biology over the past 50 years have resolved the general outlines this capacity for adaptation on the scale of molecules. We now view an organism’s ability to adapt as the result of many complex programs of gene expression. As a basic science, the improved resolution of these expression programs has proved invaluable
in understanding many clinical pathologies, the most dramatic being cancer. My
laboratory work has focused on resolving a process cells use, at the level of messenger
RNA (mRNA), to turn off genes before functional proteins are made. This enzymatic
process involves the break down of mRNA polymers where the degrading enzymes
are recruited by specifi c adaptor proteins to specifi c sets of mRNA. One of these
adaptor proteins is CUG-binding protein 1 (CUGBP1) and identifying the mRNA set
CUGBP1 targets has been a focus of our lab. The degradation proteins which CUGBP1 targets to the mRNA are only poorly resolved. I am using a yeast-two
hybrid screen to identify CUGBP1 binding candidates. These candidates will then be
con firmed by co-immunoprecipitation and mRNA a ffinity chromatography. This will
allow me to characterize the specifi c mechanism of decay elicited by the function of CUGBP1.Jeschke, Jonathan C.. (2009). Fishing for Function: Identifying Functional Binding Partners of CUG-Binding Protein 1. Retrieved from the University Digital Conservancy, https://hdl.handle.net/11299/50378
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
The citizen science project ‘Mückenatlas’: contributions of opportunistic data collection to mosquito research in Germany
Full text linkCitizen science – the involvement of the public in scientific research – has become an emerging field, both as a research approach and as a discipline (the science of citizen science) by itself. The ‘Mückenatlas’ (German for ‘mosquito atlas’) was launched in 2012, shortly before citizen science also gained momentum in Germany. The goal of the ‘Mückenatlas’ is to support mapping the occurrence and distribution of native and introduced mosquito species. Therefore, people collect and submit physical mosquito samples to the responsible research institutions. In return, participants receive an individual answer with information about the biology of the captured spe¬cies and, if desired, a personal marker on the collectors’ map on the ‘Mückenatlas’ website. In this thesis, the project was evaluated from three perspectives, based on current controversies in citizen science: as a monitoring method, as a data source, and as a public outreach activity. The general aim of the dissertation was to assess the contributions of the opportunistic data collection of the ‘Mückenatlas’ project to mosquito research in Germany.
The ‘Mückenatlas’ performance as monitoring method was evaluated by comparing it to a professional monitoring approach. The results showed that monitoring by professionals allows for a better coverage of land use types and species richness, whereas the citizen science approach provides important data from urban areas and can very well detect invasive species. By investigating the ‘Mückenatlas’ data collection as data source for research, anthropogenic and environmental factors were identified as drivers of the spatio-temporal variation in the numbers of submissions. Despite this bias, a study of the effects of urbanisation on indoor mosquito communities showed that opportunistic data have the capacity to confirm findings and generate novelty. Finally, considering the ‘Mückenatlas’ as an outreach activity demonstrated the positive association of mass media reports with the number of submissions across time and space. In addition, the style of the titles and texts of media reports, as well as an already raised media and public attention towards mosquito topics, increased the responsiveness of participants.
The findings of this thesis show that the opportunistic data collection of the ‘Mückenatlas’ can make a crucial contribution to mosquito research, especially in gaining insights into species occurrence through the sheer number of samples submitted. Recommendations are made on when and how citizens can be involved in formal mosquito monitoring programmes, what biases and patterns to consider in data analysis, and how communication strategies can influence participation and affect the data
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
