What Is Learning Analytics? At its core, learning analytics (LA) is the collection and analysis of usage data associated with student learning. The purpose of LA is to observe and understand learning behaviors in order to enable appropriate interventions. The reports that an LA application generates can be very helpful for instructors (about student activities and progress), for students (feedb...

The proposed study begins with the assumption that individuals differ in their vulnerability to develop drug abuse. Therefore, a crucial step in developing prevention and treatment programs for drug abuse is the identification of the biobehavioral basis of the vulnerability. The proposed study is a type of high-risk study using only identical (monozygotic, MZ) twins, rather than a conventional ...

Previously proposed usage analyses have proved not to scale up well for large programs. In this paper we present a powerful and accurate type based analysis designed to scale up for large programs. The key features of the type system are usage subtyping and bounded usage polymorphism. Bounded polymorphism can lead to huge constraint sets and to express constraints compactly we introduce a new e...

BACKGROUND This paper explores whether at different stages of the developmental cycle of adolescence, drug use and offending are associated with a similar set of risk factors relating to: socio-structural position, informal social control, deviant peer group contexts, and deviant lifestyle behaviours. METHODS Multivariate regression was used to analyse data from the Edinburgh Study of Youth T...

A lthough guidelines suggest physicians should not treat themselves, the self-prescription of medications is common. Self-prescription among physicians in training is of particular concern, given their limited clinical experience and high levels of work stress. In the only large multicenter study conducted to date, to our knowledge,Christie et al found that self-prescribing iswidespread, with 5...

BACKGROUND An understanding of the needs and behaviors of asthma patients is important in developing an asthma-related healthcare policy. The primary goal of the present review was to assess patient perspectives on key issues in asthma and its management, as captured in patient surveys. METHODS Local, national, and multinational asthma surveys were reviewed to assess patient perspectives, and...

This paper compares two projects that adopted social bookmarking (SB) technology in different educational contexts at the same institution, a large, research-intensive university in the north of England. The first study used social bookmarking in a multicultural postgraduate class to increase interactivity within the whole class and to produce an archive of course-related online resources to en...

There are many different ways and models how to characterize usage data to enable representation of user actions across learning management system, and systems in general. Based on this data, learning analytics can perform different analysis and provide personalized and meaningful information to improve the learning and teaching processes. There is a variety of usage data formats that are alrea...

As part of web services life-cycle, providers frequently face decision about changes without a clear understanding of the impact on their clients. The identification of clients’ consumption patterns constitutes invaluable information to support more effective decisions. In this paper, the authors present a framework that supports the discovery of service usage profiles, to bring awareness on th...

We use data from the British Crime Survey (BCS) to analyse the relationship between illicit drug use and labour market outcomes for a sample of men and women aged 16 to 25. In using this data we highlight a serious design flaw in the BCS questionnaire structure that presents a serious barrier to statistical modelling of drug use at the individual level. We propose a simple way of overcoming thi...
