An extensible framework for provenance in human terrain visual analytics

We describe and demonstrate an extensible framework that supports data exploration and provenance in the context of Human Terrain Analysis (HTA). Working closely with defence analysts we extract requirements and a list of features that characterise data analysed at the end of the HTA chain. From these, we select an appropriate non-classified data source with analogous features, and model it as a set of facets. We develop ProveML, an XML-based extension of the Open Provenance Model, using these facets and augment it with the structures necessary to record the provenance of data, analytical process and interpretations. Through an iterative process, we develop and refine a prototype system for Human Terrain Visual Analytics (HTVA), and demonstrate means of storing, browsing and recalling analytical provenance and process through analytic bookmarks in ProveML. We show how these bookmarks can be combined to form narratives that link back to the live data. Throughout the process, we demonstrate that through structured workshops, rapid prototyping and structured communication with intelligence analysts we are able to establish requirements, and design schema, techniques and tools that meet the requirements of the intelligence community. We use the needs and reactions of defence analysts in defining and steering the methods to validate the framework

Learning and Teaching with Geomedia

International audienceThis book presents a range of educational approaches and ideas around learning with and about geomedia, taking into account the potential as well as the risks and challenges associated with the use geomedia in education. This includes understanding the inherently biasednature of maps and other spatial representations; the power of geomedia produced by institutions, as well as the power of geomedia produced by lay persons; the use of geoinformation in the control and surveillance of individuals and groups, and the opportunities of georeferenced data to foster innovative knowledge. Addressing these aspects in essence means preparing students for an emerging Geoinformation society

Social Media for small- and medium sized businesses to refer to tourism industry

Die vorliegende Bachelorarbeit befasst sich mit der Thematik, wie klein- und mittelständige Unternehmen der Tourismusbranche Social Media zur Kundenbindung, Neukundengewinnung und somit zur Geschäftsausdehnung nutzen können. Es wird auf den Nutzen von Social Media, für eine Geschäftsausdehnung eingegangen sowie auf die Leistungsfähigkeit ausgewählter Social Media Kanäle und Vor- und Nachteile dieser heraus kristallisiert. Des weiteren wird eine Umfrage und ein Interview zu der genannten Thematik aufgezeigt und analysiert

Reputation Protection on Online Rating Sites

The 21st century has witnessed a blossoming of rating, evaluation or even blacklisting sites. Namely, teachers, lawyers and doctors are rated openly by their students, clients and patients. We are living in a ‘reputation nation,’ where our conducts are evaluated often by anonymous individuals in different aspects, entailing the dangers of shame sanctions. This reputation rating system is far from being a system of formal adjudication. It may carry false or incorrect information, and may not allow an individual to correct such information. Relying on defamation law may not be helpful to the victim targeted as the defendant maybe an anonymous individual expressing his honest opinion. Equally, invoking privacy law may be a frustrating experience when the information is of legitimate public interest and it is already in the public domain. In the absence of satisfactory legal solution and remedies, some have resorted to alternative methods of “reputation management.” What has yet to be addressed is the issue of how to develop a new procedural layout that can accommodate social norms, technological advancement and the legal right to protect reputation on online platforms. This article returns to the fundamental rationale behind the protection of reputation, and argues that reputation is an inherently social and relational concept that serves a significant signaling function in society. Drawing on judicial jurisprudence in the US and Germany on online rating sites, this article advocates for a new regime that requires online rating sites to have appropriate netiquette and information policy, including the right to reply amongst other requirements. This is essential not only to protect individual’s reputation but also for establishing a reliable system for civility.postprin

Computer assisted thermal-vacuum testing

In testing complex systems and components under dynamic thermal-vacuum environments, it is desirable to optimize the environment control sequence in order to reduce test duration and cost. This paper describes an approach where a computer is utilized as part of the test control operation. Real time test data is made available to the computer through time-sharing terminals at appropriate time intervals. A mathematical model of the test article and environmental control equipment is then operated on using the real time data to yield current thermal status, temperature analysis, trend prediction and recommended thermal control setting changes to arrive at the required thermal condition. The data acquisition interface and the time-sharing hook-up to an IBM-370 computer is described along with a typical control program and data demonstrating its use
