This presentation summarizes the development of a mobile application to help users track personal health metrics. It describes an initial paper prototype of the application, followed by the creation of a digital prototype in Xcode. The digital prototype was evaluated through user testing, which provided feedback on difficulties with adding data and inconsistent views of information. Based on the feedback, future iterations of the application will allow for multiple health goals and include social networking features to encourage motivation. Statistics on the project development time and activities were also presented.

The document describes the process of developing a visualization tool to map research publications about learning analytics and educational data mining topics to their geographic locations. It discusses design choices like using pop-ups versus other visualization methods. It outlines creating paper and digital prototypes, getting expert feedback, and improving the tool based on evaluations. Key findings were that some topics are more popular in certain locations and conferences, and visualizing both was important. Future work could include more detailed information and searching capabilities.

Vittles - Quantified Self for Personal Health Anne Everars

��

The document summarizes Anne Everars' presentation on developing a mobile application to help users track personal health metrics for weight loss. It describes conducting research on existing applications, designing prototypes based on literature and evaluating them with users. Prototypes were improved based on feedback, focusing the design on easily adding food/activity items and motivation through goals rather than social/gamification features. The final conclusion was that while the design scored well overall, adding items simply and providing visual feedback could be further improved to help users better track their lifestyle and progress toward weight loss.

Draft scientific paperAnne Everars

��

This document describes the design of a mobile application called Vittles that aims to help users achieve a healthier lifestyle and lose weight.

Presentation project Computer Vision - Teeth segmentationAnne Everars

��

This document outlines a project for segmenting and classifying teeth in dental x-ray images. The key steps include pre-processing the images through grayscaling, cropping the region of interest, separating the jaws, and separating individual teeth. Teeth segmentation is done using watershedding and mean shift filtering. Potential classification methods mentioned are hamming distance, eigenfaces, and principal component analysis.

Where to go with your subject - status reportAnne Everars

��

The document discusses visualizing differences in topics between two conferences: LAK and EDM. It describes creating a map to show the geographic localization of research on various subjects for each conference based on the number of papers. Several visualization options were considered, including markers on a map, bar charts and pie charts. A paper prototype was created to test displaying information on selected locations in pop-ups. User testing revealed some interface issues to address, and the prototype scored well on a usability scale. Further refinements to the visualization were discussed.

Introduction to the Biodiversity Informatics Training CurriculumTown Peterson

��

The document outlines plans for developing a comprehensive training curriculum in biodiversity informatics. It notes that biodiversity informatics is a new field that currently lacks organized training resources. It proposes developing an in-person training course series along with online videos, subtitles, and translations to make the content broadly accessible globally. Funding has been obtained to create an initial set of course modules. Future plans include expanding the curriculum topics, translating the content into multiple languages, and potentially developing an international certificate or masters degree program in biodiversity informatics.

Data Management for librariansC. Tobin Magle

��

Librarians can provide valuable data management services to researchers on campus. An effective strategy includes surveying researchers to identify needs, communicating service offerings through workshops and consultations, and providing in-depth guidance on data management plans and long-term data preservation. Developing workshops involves setting learning objectives, evaluating content, and securing resources like space and food. Consultations allow librarians to help with specific topics like choosing file formats or finding metadata standards. Creating a data management plan requires detailing a data inventory, metadata description, long-term preservation and access methods. Trusted disciplinary repositories and use of stable identifiers help ensure long-term findability and access.

The document discusses biodiversity informatics training and resources. It notes that biodiversity informatics is a new field without established training programs or textbooks. It proposes the Biodiversity Informatics Training Curriculum (BITC) to address this need. BITC would include in-person training courses along with online videos, subtitles, and translations to make the materials broadly accessible. It outlines the curriculum topics and plans for future expansion, including additional modules, languages, and regions. It also provides suggestions for a Taiwanese biodiversity informatics program, including translating BITC, developing a national biodiversity assessment, capturing older data from overseas collections, and building training opportunities.

Notes Profiling a Program w/ Available DataShalin Hai-Jew

��

Today’s session explores ways to profile a program or department or bureaucratic unit, so that that data is available when it comes time to write a grant proposal, write a grant report, or use documented information for other programmatic purposes. So much is known by insiders to a program, and so much is at their fingertips, but it can be difficult to acquire the needed information for the necessary work. This session suggests that some initial and continuing effort to document a program or department would be beneficial. This is an exercise in “know thyself” as a bureaucratic unit.

- The document discusses the need for open and accessible data in research. It notes that over 50% of studies are not published due to selective reporting of results. - There is a movement for "FAIR data" in life and medical sciences, where data is findable, accessible, interoperable, and reusable. However, not much data currently meets these standards. - Publishers can play a role in incentivizing data sharing by implementing policies requiring data availability and format standards for publishing research. This includes supporting data citations and data journals.

Technology training for PG studentsJez Cope

��

The document summarizes talks given by Jez Cope at the Oxford Open Science meeting about technology training provided to postgraduate students at the University of Bath. It describes two projects Cope worked on: 1) Connected Researcher @ Bath which involved workshops to promote social media use among researchers, and 2) research data management workshops for postgraduate students to develop practical data management strategies. Feedback from students indicated high satisfaction with the courses but low levels of actual implementation of data management plans. The document concludes that postgraduate students are aware of technologies' potential but wary of risks, and are influenced by supervisors but also influence them.

What is ‘research impact’ in an interconnected world?Danny Kingsley

��

This talk looks at what researchers need to do to ensure their research is widely disseminated and reaches the largest audience possible. In summary: Publishing a paper is the beginning not the end; Making work open access does not mean it is accessible; Writing in plain language is translating, not dumbing it down; Sharing work involves peer networks and publishing platforms and If you don't take control of your online presence someone/something else will. The presentation was originally given as part of the Cambridge University Alumni Festival on 27 September 2015.

Teaching Data Science to Undergraduate StudentsNicole Vasilevsky

This document summarizes Nicole Vasilevsky's presentation on teaching data science to undergraduate students. It discusses the need for data science training, the open educational resources (OERs) developed by OHSU Library to address this need, and workshops offered including "Data and Donuts". The OERs cover the entire research process, from finding data to analysis to sharing results. Workshops are hands-on and interactive. Future plans include continuing "Data and Donuts" and potentially a larger OHSU Library Data Science Institute. The overall goal is to provide accessible data science training to address the growing demand.

How metadata drives data sharing; UK Data Archive Louise Corti

��

The document discusses metadata and its importance for archiving survey data. It summarizes that metadata drives access to survey data through online browsing systems by providing essential documentation about the variables, questions, and structure of the surveys. It notes common issues with deposited survey metadata including a lack of consistent variable naming and incomplete documentation of changes over time. Improving metadata practices throughout the data lifecycle from production to archiving is important to support reuse of the data.

Formal Methods: Whence and Whither? [Martin Fränzle Festkolloquium, 2025]Jonathan Bowen

��

Alan Turing arguably wrote the first paper on formal methods 75 years ago. Since then, there have been claims and counterclaims about formal methods. Tool development has been slow but aided by Moore’s Law with the increasing power of computers. Although formal methods are not widespread in practical usage at a heavyweight level, their influence as crept into software engineering practice to the extent that they are no longer necessarily called formal methods in their use. In addition, in areas where safety and security are important, with the increasing use of computers in such applications, formal methods are a viable way to improve the reliability of such software-based systems. Their use in hardware where a mistake can be very costly is also important. This talk explores the journey of formal methods to the present day and speculates on future directions.
