This article provides an analysis of the academic performance of higher education institutions (HEIs) in Vietnam with 50 universities and 50 colleges in 2011/12. The two-stage semiparametric data envelopment analysis is used to estimate the efficiency of HEIs and investigate the effects of various factors on their performance. The findings reveal…

The present study explores the perceptual span, that is, the physical extent of the area from which useful visual information is obtained during a single fixation, during oral reading of Chinese sentences. Characters outside a window of legible text were replaced by visually similar characters. Results show that the influence of window size on the…

National attention on whole-of-school approaches to decrease children's sedentary behavior and increase physical activity includes movement integration (MI) in classrooms. The purpose of this study was to describe instrument development, reliability, and validity of the System for Observing Student Movement in Academic Routines and Transitions…

Research on cultural factors and substance use among Hispanic adolescents has focused primarily on acculturation, while specific core Hispanic values and attributes have received minimal attention. The objective of the current study was to examine the relationship between traditional Hispanic cultural assets and substance use among adolescents. A…

The study aimed at assessing how students and teachers factor taken together influence students' achievement in Statistics as well as their relative contribution to the prediction. Two research questions were raised and purposive sampling was adopted to select national diploma year 2 students since they are already in their final level in the…

Model uncertainty is pervasive in social science. A key question is how robust empirical results are to sensible changes in model specification. We present a new approach and applied statistical software for computational multimodel analysis. Our approach proceeds in two steps: First, we estimate the modeling distribution of estimates across all…

Humans' face ability develops and matures with extensive experience in perceiving, recognizing, and interacting with faces that move most of the time. However, how facial movements affect 1 core aspect of face ability--holistic face processing--remains unclear. Here we investigated the influence of rigid facial motion on holistic and part-based…

By means of a regression-discontinuity approach with multiple cut-off points, the effects of age and schooling on learning gains in English primary schools are estimated. The analyses relate to over 3,500 pupils in 20, predominantly independently funded, schools and focus on 4 different learning outcomes. In order to take into account delayed and…

We address the task of determining, from statistical averages alone, whether a population under study consists of several subpopulations, unknown to the investigator, each responding to a given treatment markedly differently. We show that such determination is feasible in three cases: (1) randomized trials with binary treatments, (2) models where…

In many modeling contexts, the variables in the model are linear composites of the raw items measured for each participant; for instance, regression and path analysis models rely on scale scores, and structural equation models often use parcels as indicators of latent constructs. Currently, no analytic estimation method exists to appropriately…

Learning curves are a useful way of representing the rate of learning over time. Features include an index of baseline performance (y-intercept), the efficiency of learning over time (slope parameter) and the maximal theoretical performance achievable (upper asymptote). Each of these parameters can be statistically modelled on an individual and…

Although mentoring is believed to improve the craft of beginning principal, the context of collective engagement between mentor and mentee principals that optimize their leadership learning are rarely investigated. This study explored co-creating dispositional values, knowledge conversion modes, and enabling conditions as contexts that favor the…

Most recent publications related to listening comprehension research deal with listening strategy instruction, metacognitive instruction or multimedia applications. This paper discusses one study from each of these three domains--Graham & Macaro (2008), Vandergrift & Tafaghodtari (2010) and Brett (1997)--and presents the need and…

Theories of visual narrative understanding have often focused on the changes in meaning across a sequence, like shifts in characters, spatial location, and causation, as cues for breaks in the structure of a discourse. In contrast, the theory of visual narrative grammar posits that hierarchic "grammatical" structures operate at the…

Purpose: Artificial airway procedures such as intubation and Sare common in the treatment of traumatic injuries, and bolus modifications may be implemented to help manage swallowing disorders. This study assessed artificial airway status, bolus properties (volume and viscosity), and the occurrence of laryngeal penetration and/or aspiration in…
