Longitudinal, Educational Design Research Investigation of the Temporal Nature of Learning: Taking a Vygotskian Approach
The nature of learning is being augmented by new digital tools, particularly by mobile devices and the networks and structures to which they connect people. In this paper I examine some longitudinal research 'threads' that have pervaded my work over the last two decades: (i) the powerful…

Association between Prepartum Alerts Generated Using a Commercial Monitoring System and Health and Production Outcomes in Multiparous Dairy Cows in Five UK Herds
Identifying cows that are at greater risk for disease prior to calving would be a valuable addition to transition management. Prior to the commercial release of software features in an automated behavioral monitoring system, designed to identify cows in the dry period at greater risk of disease…

The Role of Dialogue in Computer-Based Learning and Observing Learning: An Evolutionary Approach to Theory
Abstract: This paper examines two sides of a coin that relate to learning from dialogue. The first side of our coin relates to the role of dialogue in learning; the second side is related to the part that observations of learning dialogues can play in the design of computer-based learning…

Reliability of Extreme Wind Speeds Predicted by Extreme-Value Analysis
The reliability of extreme wind speed predictions at large mean recurrence intervals (MRI) is assessed by bootstrapping samples from representative known distributions. The classical asymptotic generalized extreme value distribution (GEV) and the generalized Pareto (GPD) distribution are compared…

Impact of ASOS Real-Time Quality Control on Convective Gust Extremes in the USA
Most damage to buildings across the contiguous United States, in terms of number and total cost, is caused by gusts in convective events associated with thunderstorms. Their assessment relies on the integrity of meteorological observations. This study examines the impact on risk due to valid gust…

Extreme Convective Gusts in the Contiguous USA
Most damage to buildings across the contiguous United States of America (USA) is caused by gusts in convective events associated with thunderstorms. Design rules for structures to resist these events rely on the integrity of meteorological observations and the methods of assessment. These issues…

Understanding and using technological affordances: a commentary on Conole and Dyke
The paper by Conole and Dyke sets the context by pointing to a number of problems that inhibit the widespread, effective use of Information and Communication Technologies (ICT) to support learning. They argue that this situation highlights the need to explore a theoretical basis for the use of ICT…

Coleridge: a computer tool for assisting musical reflection and self-explanation
Since the mid-1980s, there has been a movement away from knowledge supplied by the teacher and towards talking, reflecting and explaining as ways to learn. An example of this change in focus is provided by the self-explanation work of Chi et al (1994) who describe an approach to talking science…

Online interactivity: best practice based on two case studies
This paper compares the experiences of two studies in the use of network supported collaborative learning. These studies aimed to enhance the learning experience of traditional campus-based students. The courses used a hybrid of face-to-face contact and collaborative work mediated through…

Intravenous Vitamin C for Cancer Therapy – Identifying the Current Gaps in Our Knowledge
The use of intravenous vitamin C (IVC) for cancer therapy has long been an area of intense controversy. Despite this, high dose IVC has been administered for decades by complementary health care practitioners and physicians, with little evidence base resulting in inconsistent clinical practice. In…

Skeptical and Optimistic Robust Priors for Clinical Trials Ensayos clínicos bajo un enfoque bayesiano robusto con previas escépticas y optimistas
A useful technique from the subjective Bayesian viewpoint, is to ask the subject matter researchers and other parties involved, such as pharmaceutical companies and regulatory bodies, for reasonable optimistic and pessimistic priors regarding the effectiveness of a new treatment. Up to now, the…

Online learning for design students
During the last five years, many changes have taken place in undergraduate Design education in the UK. The main force behind these changes has been the dramatic increase in the number of students without a commensurate increase in teaching staff. Typically, many Design departments are now teaching…

Mobile phones as cultural resources for learning – an analysis of mobile expertise, structures and emerging cultural practices
If it is the case that mobile devices, with their specific social and technological structures and attendant cultural practices, have become an integral part of everyday life, then the educational field has to react. But how and who? Fact is that mobile devices have reached and become fully…
