BackgroundSitting on inappropriate benches, as well as the poor posture (body position) during the years of growth, can lead to spinal disorders, fatigue and discomfort in students. This study aimed to investigate the relationship between features of desks and chairs and prevalence of some musculoskeletal disorders in primary school students in Abadan.Materials and MethodsThis cross-sectional s...

This Coastal and Hydraulic Engineering Technical Note (CHETN) summarizes the state of understanding of the influence of grain size on surf zone sediment transport and is a companion to Smith et al. (2004). This CHETN discusses details of bed-load and suspended load transport, and the classical bed-load regime is shown to encompass two distinct modes of transport. Four LST models with varying le...

In face processing tasks, prior presentation of internal facial features, when compared with external ones, facilitates the recognition of subsequently displayed familiar faces. In a previous ERP study (Olivares & Iglesias, 2010) we found a visibly larger N400-like effect when identity mismatch familiar faces were preceded by internal features, as compared to prior presentation of external ones...

This paper describes the methods we have employed to solve the author profiling task at PAN-2013. Our goal was to use simple features to identify the age group and the gender of the author of a given text. We introduce the features, detail how the classifiers were trained, and how the experiments were run.

Language students are most engaged while reading texts at an appropriate difficulty level. However, existing methods of evaluating text difficulty focus mainly on vocabulary and do not prioritize grammatical features, hence they do not work well for language learners with limited knowledge of grammar. In this paper, we introduce grammatical templates, the expert-identified units of grammar that...

The current study identifies relations among students’ natural language input, individual differences in reading commitment, and learning gains in an intelligent tutoring system. Students (n = 84) interacted with iSTART across eight training sessions. Linguistic features of students’ generated self-explanations (SEs) were analyzed using Coh-Metrix. Results indicated that linguistic properties o...

medical curriculum can exposed the medical students to a significant levels of mental pressure. therefore, the prevalence and incidence of psychiatric disorders including abnormal value of stress, depression and anxiety are higher in the schools of medicine. there are two major types of sources that can lead to stress and further mental problems in the medical students: 1. stresses related to t...

Although feedback is often seen as a critical component of the learning process, many open questions about how specific feedback features contribute to the effectiveness of feedback remain— especially in regards to peer feedback of writing. Nelson and Schunn (2009) identified several important features of peer feedback in their nature of feedback model. In the current study, we test an updated ...
