Entering the Mainstream: The Quality and Extent of Online Education in the United States, 2003 and 2004
Presents key findings from a survey of over 1,100 colleges and universities that looks at the growth of online enrollments, the quality of online offerings, student satisfaction, and the role of online learning in the long-term strategy of schools
Sizing the Opportunity: The Quality and Extent of Online Education in the United States, 2002 and 2003
Presents key findings from a survey that details the quality of online learning, which institutions offer online courses, what types of courses are offered, characteristics of online learners, and growth forecasts for online education
Disability, ICT and eLearning Platforms: Faculty-Facing Embedded Work Tools in Learning Management Systems
This paper contributes to the current discussion in the field of human-computer interaction design (HCI) on the accessibility and design of eLearning tools embedded in the online platforms for higher education. Presenting the preliminary results of a longitudinal study of the accessibility of the faculty-facing pages of Canvas learning management system, it aims at drawing the attention of designers, developers, and manufacturers to the barriers erected by the ableist LMS designs for disabled faculty. The paper asks for improvements in design processes by embracing participatory design methods and by paying attention to the recommendations included in this paper

Visuospatial Functioning In The Primary Progressive Aphasias
Objectives: The aim of this study was to identify whether the three main primary progressive aphasia (PPA) variants would show differential profiles on measures of visuospatial cognition. We hypothesized that the logopenic variant would have the most difficulty across tasks requiring visuospatial and visual memory abilities. Methods: PPA patients (n = 156), diagnosed using current criteria, and controls were tested on a battery of tests tapping different aspects of visuospatial cognition. We compared the groups on an overall visuospatial factor; construction, immediate recall, delayed recall, and executive functioning composites; and on individual tests. Cross-sectional and longitudinal comparisons were made, adjusted for disease severity, age, and education. Results: The logopenic variant had significantly lower scores on the visuospatial factor and the most impaired scores on all composites. The nonfluent variant had significant difficulty on all visuospatial composites except the delayed recall, which differentiated them from the logopenic variant. In contrast, the semantic variants performed poorly only on delayed recall of visual information. The logopenic and nonfluent variants showed decline in figure copying performance over time, whereas in the semantic variant, this skill was remarkably preserved. Conclusions: This extensive examination of performance on visuospatial tasks in the PPA variants solidifies some previous findings, for example, delayed recall of visual stimuli adds value in differential diagnosis between logopenic variant PPA and nonfluent variant PPA variants, and illuminates the possibility of common mechanisms that underlie both linguistic and non-linguistic deficits in the variants. Furthermore, this is the first study that has investigated visuospatial functioning over time in the PPA variants
Students’ achievement and opinions on the implementation of e-learning for phonetics and phonology lectures at Airlangga University
Abstract The demand of e-learning at higher education has increased significantly in the past several years. In Indonesia, the implementation of e-learning has been encouraged by the government since 2011. However, universities are still looking for the most appropriate e-learning system, and unsure of the effectiveness of e-learning program. This paper discusses the implementation of e-learning system at Airlangga University, one of the top five state-owned universities in Indonesia. The e-learning system implemented in this university follows the Seven Principles of Good Practice in Undergraduate Education, i.e. encourage contacts between student and faculty; develop reciprocity and cooperation among students; use active learning techniques; give prompt feedback; emphasize time on task; communicate high expectations; and respect diverse talents and ways of learning. The e-learning platform at this university is called AULA (Airlangga University e-Learning Application). The respondents of this study were the students who took the General Linguistics course, particularly for the lectures on Phonetics and Phonology. Based on the t-test calculation of the exam scores, we conclude that there is no significant difference between the results of the e-learning and those of the classroom learning. The results of questionnaires show that 85% of the students are satisfied with the implementation of e-learning as they think that the e-learning makes it easier for them to understand the materials, it is fun, and is convenient to access. For further implementation, the students suggested the additions of podcasts and games, more time for the quizzes, and improvement of the e-learning platform
Human metabolic profiles are stably controlled by genetic and environmental variation
A comprehensive variation map of the human metabolome identifies genetic and stable-environmental sources as major drivers of metabolite concentrations. The data suggest that sample sizes of a few thousand are sufficient to detect metabolite biomarkers predictive of disease
A Genome-Wide Metabolic QTL Analysis in Europeans Implicates Two Loci Shaped by Recent Positive Selection
We have performed a metabolite quantitative trait locus (mQTL) study of the 1H nuclear magnetic resonance spectroscopy (1H NMR) metabolome in humans, building on recent targeted knowledge of genetic drivers of metabolic regulation. Urine and plasma samples were collected from two cohorts of individuals of European descent, with one cohort comprised of female twins donating samples longitudinally. Sample metabolite concentrations were quantified by 1H NMR and tested for association with genome-wide single-nucleotide polymorphisms (SNPs). Four metabolites' concentrations exhibited significant, replicable association with SNP variation (8.6×10−11<p<2.8×10−23). Three of these—trimethylamine, 3-amino-isobutyrate, and an N-acetylated compound—were measured in urine. The other—dimethylamine—was measured in plasma. Trimethylamine and dimethylamine mapped to a single genetic region (hence we report a total of three implicated genomic regions). Two of the three hit regions lie within haplotype blocks (at 2p13.1 and 10q24.2) that carry the genetic signature of strong, recent, positive selection in European populations. Genes NAT8 and PYROXD2, both with relatively uncharacterized functional roles, are good candidates for mediating the corresponding mQTL associations. The study's longitudinal twin design allowed detailed variance-components analysis of the sources of population variation in metabolite levels. The mQTLs explained 40%–64% of biological population variation in the corresponding metabolites' concentrations. These effect sizes are stronger than those reported in a recent, targeted mQTL study of metabolites in serum using the targeted-metabolomics Biocrates platform. By re-analysing our plasma samples using the Biocrates platform, we replicated the mQTL findings of the previous study and discovered a previously uncharacterized yet substantial familial component of variation in metabolite levels in addition to the heritability contribution from the corresponding mQTL effects
