Good teachers know their students, and exploit this knowledge to adapt or optimise their instruction. Teachers know their students because they interact with them face-to-face in classroom or one-to-one tutoring sessions. They can build student models, for instance, by exploiting the multi-faceted nature of human-human communication. In distance-learning environments, teacher and student have t...

Citation and print journal use data have been used to measure quality and usefulness of library journal titles. This study examined relationships among different measurements and found that electronic usage correlates with print usage and local citation data are a valid reflection of total journal usage but Impact Factors are not as valid.

This study investigated the social adjustment of female family members and significant others (FSOs) of illicit drug users in order to gain insight into the impact of drug use upon those close to the user. Using the Social Adjustment Scale-Self Report (SAS-SR), we examined the social adjustment self-ratings (overall and in seven specific role areas) of 41 female partners and 24 mothers of drug ...

More than two decades ago, attention was called to the uncontrolled spread of injecting drug use in many Asian countries and the virtually unnoticed but rapid spread of HIV among those who were injecting [1]. It was pointed out that constantly changing trafficking routes from the Golden Triangle were exposing new populations to the use and subsequent injecting of heroin, that these populations ...

BACKGROUND Among a cohort of drug-using street-involved youth, we sought to identify the prevalence of reporting increases and decreases in illicit drug use due to their current housing status and to identify factors associated with reporting these changes. FINDINGS This longitudinal study was based on data collected between June 2008 and May 2012 from a prospective cohort of street-involved ...

This article investigates the influence of perception that is altered by psychedelic drugs on processes of creativity through a case study of the work of well-known comic artist Robert Crumb. Samples of Crumb's work before, during, and after the period of his use of psychedelic drugs are content analyzed and compared according to the categorization offered by Janiger and Dobkin de Rios (1989). ...

We consider the situation in which a group of agents are trying to find an agreeable time for a meeting. Each agent’s availability is governed by a known prior probability distribution, but the realization of it is private information. The goal (of the convener) is to find an agreeable time slot while optimizing in two dimensions: Expected time to reach agreement and expected inconvenience caus...

In an age when we can sequence an entire genome within a day, we expect to be able to gather and access accurate information at a pace. After all, you didn't wait for this issue of PLoS Medicine to arrive in the post or trudge down to the library to read it; you accessed it instantly via the internet. Patients and clinicians also expect technology to provide similar speed when it comes to diagn...

Complete genomic sequence data are stored in the public GenBank/EMBL/DDBJ databases so that any investigator can make use of the data. This report describes a comparative analysis of codon usage that is impossible without such a public and open data system. A limited number of bacteriophages harbor their own transfer RNAs. Based on a comparison between T4 phage-encoded tRNA species and the rela...
