Through a sensitivity analysis, the analyst attempts to determine whether a conclusion of causal inference could be easily reversed by a plausible violation of an identification assumption. Analytic conclusions that are harder to alter by such a violation are expected to add a higher value to scientific knowledge about causality. This article…

This article reports the results of an examination of the endorsement, reliability, and factorial validity of the VIA--Youth and assessment of character strengths and virtues developed for the general population in youth with and without intellectual disability. Findings suggest that, generally, youth with intellectual disability endorsed…

Young children learn multiple cognitive skills concurrently (e.g., language and music). Evidence is limited as to whether and how learning in one domain affects that in another during early development. Here we assessed whether exposure to a tone language benefits musical pitch processing among 3-5-year-old children. More specifically, we compared…

Randomization of large number of participants to different treatment groups is often not a feasible or preferable way to answer questions of immediate interest to professional practice. Single case designs (SCDs) are a class of research designs that are experimental in nature but require only a few participants, all of whom receive the…

This study aimed at evaluating why, despite the introduction of free prison education, prisoners in Uganda have lower formal and vocational skills compared to the general population. The study was basically quantitative and a cross sectional survey design was used. The study population comprised eight hundred convicted adult male and female…

Background:The ability to forge connections between academic study and real-world experience is essential in service learning (SL). Furthermore, the transition out of SL projects can be emotionally charged for both students and service recipients; yet, little research has been conducted on this topic. Purpose: This study aimed (a) to compare…

This paper is based on a neo-functionalist constructivist theory, allowing us to understand that dialogue processes and social participation build culture with a dynamic and civic vision, as opposed to organic and more conservative visions. The main objective is to create a panel analysis of plays, from the point of view of drama (sense) and…

Our research addresses the issue of teaching and learning concepts in science education as an empirical question. We study the process of conceptualization by closely examining the unfolding of classroom lesson sequences. We situate our work within the practice turn line of research on epistemic practices in science education. We also adopt a…

Consider a chain of length L that hangs in a U shape with end A fixed to a rigid support and free end E released from rest starting from the same initial height (call it y = 0) as A. Figure 1 sketches the chain after end E has fallen a distance y. Points O and A are assumed to be close enough to each other and the chain flexible enough that the…

There is a great deal of literature exploring the subscription and purchase models available for streaming video. However, explorations into the use of streaming video and how it compares to that of DVDs have not been done. The author identified a sample set of films at Penn State University Libraries owned in DVD format and available on the…

Lately, there has been a growing interest in media. As a result, many trends are found from both the academic and industrial points of view. News channels, for example, play an important role in transmitting news about political situations, military events and other issues to people all over the world. The language used in news reports or even in…

A project was developed to introduce the core principles of repeated-measures designs. Using the levels of processing approach to memory, students are prompted to engage in either shallow, moderate, or deep processing of 54 common nouns. An unexpected recall task then measures the number of words remembered in each condition. Data from 293…

The aim of the study was to examine the changes in the acute blood lactate levels of elite taekwondo players when carrying out high-intensity interval training on Spinning® bikes. Twenty elite-level taekwondo athletes participated in the study. The subjects were selected from athletes who had been competitors for at least six years. Their average…

In this study, we use Mathematical Quality of Instruction (MQI), a content-specific observation framework, to examine the mathematical quality of instruction of three focal lessons in order to examine the instructional aspects illuminated by this framework as well as discuss those aspects not captured by MQI. While prior work provides evidence on…

Purpose: The purpose of this study was to review treatment studies of semantic feature analysis (SFA) for persons with aphasia. The review documents how SFA is used, appraises the quality of the included studies, and evaluates the efficacy of SFA. Method: The following electronic databases were systematically searched (last search February 2017):…
