Information is the principle driver of competitive advantage. How it is collected, analysed and communicated determines our success. No single resource is more critical to organisational survival.
The amount of data in the world is exponentially increasing, to a point where companies capture significant amounts of information about their customers, suppliers, and operations. Millions of networked sensors are being embedded in everything from mobile phones to cars. Social networks and location data from mobile devices will continue to fuel this exponential data growth. These huge data pools are commonly being referred to as "big data".
This talk examines how analytics and big data are exploiting information to drive competitive advantage.
Confronting Reality with Big Data & Learning Analytics
We are experiencing an explosion in the quantity of data available online from archives and live streams. Learning Analytics is concerned with how educational research, and learning platform design, can make more effective use of such data (Long & Siemens, 2011). Improving outcomes through the analysis of data is of interest to researchers, administrators, systems architects, social media developers, educators and learners. Analytics are being held up by some as a way to confront, and tackle, the tough new realities of less money, less attention, and higher accountability for quality of learning.
Researchers and vendors are building reporting capabilities into tools that provide unprecedented levels of data on learners. This symposium will show what is possible, and what's coming soon. What objections could possibly be raised to such progress?
However, information infrastructure embodies and shapes worldviews: classification schemes are not only systematic ways to capture and preserve, but also to forget, by virtue of what remains invisible (Bowker & Star, 1999). Learning analytics and recommendation engines are designed with a particular conception of ‘success’, driving the patterns deemed to be evidence of progress, the interventions that are deemed appropriate, the data captured and the rules that fire in software.
This symposium will air some of the critical arguments around the limits of decontextualised data and automated analytics, which often appear reductionist in nature, failing to illuminate higher order learning. There are complex ethical issues around data fusion, and it is not clear to what extent learners are empowered, in contrast to being merely the objects of tracking technology. Educators may also find themselves at the receiving end of a new battery of institutional ‘performance indicators’ that do not reflect what they consider to be authentic learning and teaching.
This Symposium will provide the opportunity to hear a series of brief presentations introducing contrasting perspectives, before the debate is opened to all. Speakers from a cross-section of The Open University will describe how we are connecting datasets, analysing student data and prototyping next generation analytics. Complementing this, JISC will present a national capability perspective, with an update on the JISC CETIS ‘landscape analysis’ of the field, which will clarify potential benefits, issues to consider, and help institutions to assess their current capability and possible next steps.
Participants will catch up with developments in this fast moving field, through exposure to the possibilities of analytics, as well as issues to be alert to.

Scalable Data Visualization Methods for Academic Careers
Kyeongan (Karl) Kwon
PhD Dissertation
Department of Computer Science

Monday July 18, 2016
Abstract
In this dissertation, I have developed scalable data visualization methods to depict a scholar's accomplishments at a glance. The evaluation of scholarly achievements in academia is largely based on the researcher's publication record. This record is communicated in exhaustive detail in the researcher's curriculum vitae (CV) or in summary via her/his h-index. The h-index, although a convenient abstraction, does not consider neither the time of the publication nor the impact factor (IF) of the journal where it appeared. I present a novel method that visually complements the h-index, revealing at a glance the nature of a researcher's scholastic record. This method (which includes the visualizations Scholar Plot and Academic Garden) is particularly appropriate for web interfaces, as it produces information that is compact and simple, yet highly illuminating.
Scholar Plot uses Google Scholar, Impact Factor, and NSF/NIH/NASA funding data to create a temporal representation of a researcher's publication/funding record that blends publication prestige with paper popularity and funding information. Scholar Plot affords an insightful appraisal of academics at one's fingertips. Academic Garden applies to individual academics, departments, colleges, and any other academic group thereof, such as a research lab or a project team. Academic Garden uses the flower metaphor to visually articulate performance of academic entities. The width of the flower's stem is commensurate to the academic funding the entity received (`juice conduit'). The height of the flower's stem is commensurate to the impact of the entity's intellectual products (`visibility'). The diameter of the flower's disc is commensurate to the prestige of the venues where these products appeared (`fancy factor'). Scholar Plot and Academic Garden bring clarity, transparency, and fairness in hiring, promotion, tenure, and funding decisions.
For the validation of the Academic Garden, I ran data analysis using Endowed Chaired Faculty, a prestigious honor in the United States, for the top 10 universities according to the US News Report 2015. The analysis demonstrated that chaired faculty can be predicted using the 3 merit criteria of citations, impact factor, and funding.
Citizen science at informal science education institutions workshop slidesCitizenScience.org
Citizen science programs have the potential to increase participants' knowledge of science content and processes, engagement with science, and development of skills like data collection and analysis. Science centers are well positioned to develop citizen science programs that can provide learning experiences for visitors and meaningful data for scientific research. Evaluating these programs can measure their impact on outcomes like knowledge, attitudes, behaviors, and scientific literacy.
This document summarizes DigiSight's mission to integrate mobile diagnostic tools into clinical care. It describes that DigiSight currently works with 13 ophthalmic tests on mobile applications and is developing additional tools like fundus imaging and IOP monitoring. The product is a single, secure portal that unites diagnostic data into a complete clinical view for physicians. Use cases show benefits for clinical care, financial performance, and research. Clinical studies have been completed and major partners include retinal specialists. Ophthalmology is a good specialty to start in given concentrated providers and large, motivated patient populations for conditions diagnosed using mobile tools.
This document summarizes the findings of the ERIAL project, an ethnographic study of how students find and use information at academic libraries. The project used interviews and diaries with over 700 students and faculty. It found that students approach research like Google searches, relying on simple keyword searches and iterative searching rather than refining searches. Students also tend to cursorily evaluate sources based on accessibility rather than accuracy. The search tools available to students influence which sources they utilize. The study suggests libraries need to better understand student information behaviors and design tools and instruction with their practices in mind.
Connecting Physicians and iPads to Support Patient Careevardell
This document discusses using iPads in clinical settings for patient education and care. It provides examples of how iPads can be used to look up information at the patient's bedside, display images and videos, and complete electronic forms and questionnaires. Barriers to iPad adoption like cost and technical issues are addressed. Results from a pilot study show promise for using iPads for these functions. Overall, the document argues that iPads show potential to improve patient care and education if implementation challenges can be overcome.

This is a presentation I delivered at a "Intelligence Strategies for Law Enforcement" conference in March 2010 in Pretoria. The focus was what analysts\' role is and what contribution they can make to the fight against crime. I represented the International Association for Law Enforcement Intelligence Analysts (IALEIA). You might find slide 5 with the 4 steps in the Intel cycle useful to describe to your colleagues what they can expect from you in all phases of the Intel process. I was a bit disappointed with the conference, as the organizers have definitely not done research to understand the topic themselves or get speakers that understand even the basics of intelligence....

Pivotal role of Intelligence analysts in intelligence-led-policingDalene
Intelligence analysts play a pivotal role in supporting law enforcement. Their work involves strategic analysis like environmental scanning and indicator development as well as operational analysis such as answering the "5Ws and H" and producing target profiles. For analysis to be successful, there needs to be a decision-making system to support, a willingness to think ahead and apply results, and information sharing across boundaries. The International Association of Law Enforcement Intelligence Analysts (IALEIA) promotes the intelligence analysis profession through training, publications, partnerships, and recognition awards. While analysis capacity is currently limited in Africa, there are signs of growing awareness and an awakening across disciplines on the continent in recent years.

56. The Science of Interaction
• Definition: The study of methods by which humans create knowledge through
the manipulation of an interface.
• …interaction and inquiry are inextricable. It is through the interactive manipulation of a visual
interface – the analytic discourse – that knowledge is constructed, tested, refined and shared.”
Stasko et al., IV2009
5 Challenges:
1.Visual Discourse - Interactive visual thinking tools for the exploration, understanding, collaboration, description,
explanation, decision, dissemination, persuasion of concepts & data.
2.Multi-modal Sensemaking In The Large - Enable large-scale, distributed teams to interactively
make sense of big multi-modal data and problems.
3.Fluid Interaction - Designing fluid, high-bandwidth, and powerful interaction models and paradigms for the purpose
of individuals reaching their full potential in viewing, analyzing, and understanding large and complex data.
4. Collaboration – beyond space and time- synergizing technologies and human users
5. Mixed Initiative Data Discovery and Manipulation - Balancing active user input with systematic
guidance to enable visual data manipulation and analysis.
April 2012
57. Visual Analytics: Remember…
• We need to be cognizant of parameters for visual
representations
• Appropriate analysis can guide users to interesting
features in the data
• Refined analysis through user interaction and their
domain knowledge can help discover hidden problems
• There is no single catch-all visual representation or
analysis
April 2012
58. Keys for Success
• User and problem driven
• Balance human cognition and automated analysis and
modeling
• Often applied on-the-fly for specific components identified by the user
• Interactivity and easy interaction
• Utilizing HPC and novel analysis approaches
• Understandability of why predicted value is what it is
• Intuitive visual cognition
• Not overloaded with features
