The future of technology enhanced active learning – a roadmap

The notion of active learning refers to the active involvement of learner in the learning process, capturing ideas of learning-by-doing and the fact that active participation and knowledge construction leads to deeper and more sustained learning. Interactivity, in particular learnercontent interaction, is a central aspect of technology-enhanced active learning. In this roadmap, the pedagogical background is discussed, the essential dimensions of technology-enhanced active learning systems are outlined and the factors that are expected to influence these systems currently and in the future are identified. A central aim is to address this promising field from a best practices perspective, clarifying central issues and formulating an agenda for future developments in the form of a roadmap

Code wars: steganography, signals intelligence, and terrorism

This paper describes and discusses the process of secret communication known as steganography. The argument advanced here is that terrorists are unlikely to be employing digital steganography to facilitate secret intra-group communication as has been claimed. This is because terrorist use of digital steganography is both technically and operationally implausible. The position adopted in this paper is that terrorists are likely to employ low-tech steganography such as semagrams and null ciphers instead

Persuading users into verifying online fake news

Abstract. Checking authenticity of fake news before sharing online can reduce spread of misinformation. But fact-checking requires cognitive and psychological effort, which people are often not willing to give. Some fact-checking methods might even be counterproductive, entrenching people into their deeply held beliefs. Numerous online fact-checking services have emerged recently which verify false claims to address the issue. While these services are quite efficient technologically, they seriously overlook human behavioral factors associated with fake news. Persuasive systems have been proven successful in attitudinal and behavioral changes, which could be applied here as behavioral interventions for fact-checking. A review of current fact-checking services showed that they significantly lack persuasive features, resulting in a passive and linear user experience. Findings from cognitive science and persuasion literature paved way for development of a fact-checking mobile application that would encourage users into regular fact-checking. Qualitative and quantitative evaluation of the artifact showed promise of persuasion in combating fake news. Social support persuasive features were found most effective, followed by tunnelling and self-monitoring. Implications of these findings and future research directions are discussed

Urban morphology analysis by remote sensing and gis technique, case study: Georgetown, Penang

This paper was analysed the potential of applications of satellite remote sensing to urban planning research in urban morphology. Urban morphology is the study of the form of human settlements and the process of their formation and transformation. It is an approach in designing urban form that considers both physical and spatial components of the urban structure. The study conducted in Georgetown, Penang purposely main to identify the evolution of urban morphology and the land use expansion. In addition, Penang is well known for its heritage character, especially in the city of Georgetown with more than 200 years of urban history. Four series of temporal satellite SPOT 5 J on year 2004, 2007, 2009 and 2014 have been used in detecting an expansion of land use development aided by ERDAS IMAGINE 2014. Three types of land uses have been classified namely build-up areas, un-built and water bodies show a good accuracy with achieved above 85%. The result shows the built-up area significantly increased due to the rapid development in urban areas. Simultaneously, this study provides an understanding and strengthening a relation between urban planning and remote sensing applications in creating sustainable and resilience of the city and future societies as well

Airborne and Terrestrial Laser Scanning Data for the Assessment of Standing and Lying Deadwood: Current Situation and New Perspectives

LiDAR technology is finding uses in the forest sector, not only for surveys in producing forests but also as a tool to gain a deeper understanding of the importance of the three-dimensional component of forest environments. Developments of platforms and sensors in the last decades have highlighted the capacity of this technology to catch relevant details, even at finer scales. This drives its usage towards more ecological topics and applications for forest management. In recent years, nature protection policies have been focusing on deadwood as a key element for the health of forest ecosystems and wide-scale assessments are necessary for the planning process on a landscape scale. Initial studies showed promising results in the identification of bigger deadwood components (e.g., snags, logs, stumps), employing data not specifically collected for the purpose. Nevertheless, many efforts should still be made to transfer the available methodologies to an operational level. Newly available platforms (e.g., Mobile Laser Scanner) and sensors (e.g., Multispectral Laser Scanner) might provide new opportunities for this field of study in the near future

Quantum surveillance and 'shared secrets'. A biometric step too far? CEPS Liberty and Security in Europe, July 2010

It is no longer sensible to regard biometrics as having neutral socio-economic, legal and political impacts. Newer generation biometrics are fluid and include behavioural and emotional data that can be combined with other data. Therefore, a range of issues needs to be reviewed in light of the increasing privatisation of ‘security’ that escapes effective, democratic parliamentary and regulatory control and oversight at national, international and EU levels, argues Juliet Lodge, Professor and co-Director of the Jean Monnet European Centre of Excellence at the University of Leeds, U

MULTISENSORY CUE CONGRUENCY IN LANE CHANGE TEST

Nowadays, a driver interacts with multiple systems while driving. Multimodal in-vehicle technologies (e.g., Personal Navigation Devices) intend to facilitate multitasking while driving. Multimodality enables to reduce cognitive effort in information processing, but not always. The present study aims to investigate how/when auditory cues could improve driver responses to a visual target. We manipulated three dimensions (spatial, semantic, and temporal) of verbal and nonverbal cues to interact with visual spatial instructions. Multimodal displays were compared with unimodal (visual-only) displays to see whether they would facilitate or degrade a vehicle control task. Twenty-six drivers participated in the Auditory-Spatial Stroop experiment using a lane change test (LCT). The preceding auditory cues improved response time over the visual-only condition. When conflicting, spatial congruency has a stronger impact than semantic congruency. The effects on accuracy was minimal, but there was a trend of speed-accuracy trade-offs. Results are discussed with theoretical issues and future works

The Pervasive Impact of Information Technology on Internal Auditing

The impetus for this supplemental chapter titled The Pervasive Impact of Information Technology on Internal Auditing comes from The Institute of Internal Auditors Research Foundation (IIARF) monograph, Research Opportunities in Internal Auditing (2003), hereafter ROIA. ROIA combines theory and practice in conceptual frameworks to promote an understanding of the contemporary internal auditing environment. The goals of ROIA include stimulating academic research on significant internal auditing topics and serving as a “communication bridge” between academics and practicing professionals. ROIA provided us with internal auditing related subject matter content, including the most promising areas of information technology (IT) application in internal auditing. One significant topic that is only briefly mentioned in ROIA is the impact of IT on the internal audit function.3 IT is revolutionizing the nature and scope of worldwide communications, changing business processes, and erasing the traditional boundaries of the organization — internally between departments and externally with suppliers and customers. The resulting intra-enterprise coordination as well as inter-enterprise integration with external business partners through supply chain management and customer relationship management systems demonstrates the power of IT as both a driver and enabler of management processes and strategies. Indeed, internal auditors must recognize and leverage the powerful capabilities of computers and technology in collecting, generating, and evaluating information for managerial decision making related to strategy, risk management and controls, and, more broadly, for effective organizational governance. At the same time, internal auditors must recognize that IT, in itself, will not increase the function’s effectiveness. Rather internal auditors must first understand the audit objectives and select appropriate IT to achieve those objectives (i.e., the task-technology fit is essential). It is also imperative that internal auditors understand their organization’s appropriate leveraging of IT, and learn to harness additional IT to optimize internal audit performance.https://ecommons.udayton.edu/books/1037/thumbnail.jp

Vendors are Undermining the Structure of U.S. Elections

As we approach the 2008 general election, the structure of elections in the United States -- once reliant on local representatives accountable to the public -- has become almost wholly dependent on large corporations, which are not accountable to the public. Most local officials charged with running elections are now unable to administer elections without the equipment, services, and trade-secret software of a small number of corporations. If the vendors withdrew their support for elections now, our election structure would collapse. Case studies presented in this report give examples of the pervasive control voting system vendors now have over election administration in almost every state, and the consequences some jurisdictions are already experiencing.However, some states and localities are recognizing the threat that vendor-dependency poses to elections. They are using ingenuity and determination to begin reversing the direction. This report examines the situation, how we got here, and steps we can take to limit corporate control of our elections in 2008 and reduce it even further in the future
