Collecting multiple perspectives data (e.g. from related individuals) in a qualitative longitudinal design can provide rich understanding of the dynamics at play in complex relational systems, and the different perceptions of people involved. However, such approaches are inherently challenging due to the complexity and volume of data involved. So…

The purpose of the study is to compare the ratio of lower extremity isokinetic hamstring/quadriceps ratio (H/Q), bilateral strength difference (BLD) and relative peak torques (RPT) in volleyball players according to the leagues. 101 volleyball players participated in the study (female=34, male=25 from 1st league; female=21, male=21 from 2nd…

This study begins the task of mapping out two approaches that may be helpful in overcoming incorrect responses to conservation tasks, focusing on the non-conserved quantity. The incorrect responses, which were the result of over-generalizations of conservation, and gradually increased with age despite formal knowledge and minor perceptual input,…

Background: Positive associations between suicidal behaviors and asthma have been established in previous adolescent studies. Few studies consider social risk factors, such as bullying. This study involved an analysis of suicidal behaviors and asthma, but also includes an assessment of whether these relationships were modified by the co-occurrence…

Based on a comparison of two nearly identical surveys in 2010 and 2016, this study examines the deepening practitioner concern over the use of social tagging within digital collections during the past six years. While participants reported a greater level of experience and increased use of social tagging, concerns regarding control, consistency,…

We present two empirical studies with 241 and 211 pre-service teachers that evaluate the explanatory power of word order matching and static comparison as models for the reversal error. We used tasks consisting of generating an algebraic equation representing a comparison given in a verbal statement. We introduce the types of magnitude involved in…

This research study provides an examination of the relatively new fields of Data Analytics and Data Science. We compare word rates in Data Analytics and Data Science documents to determine which concepts are mentioned most often. The most frequent concept in both fields is "data." The word rate for "data" is more than twice the…

Mixed methods, cross-cultural designs are a special case of the more general, mixed methods between-groups designs. The defining feature of mixed methods is the principled integration of qualitative and quantitative approaches, and cross-cultural comparison is premised on the systematic collection and analysis of data from two or more cultural…

Simulation studies are extremely common in the item response theory (IRT) research literature. This article presents a didactic discussion of "truth" and "error" in IRT-based simulation studies. We ultimately recommend that future research focus less on the simple recovery of parameters from a convenient generating IRT model,…

Our study examines the Diagnostic and Statistical Manual--Fifth Edition (DSM-5) and Diagnostic and Statistical Manual--Fourth Edition, Text Revision (DSM-IV-TR) when applied concurrently against the best estimate clinical diagnoses for 110 children (5.1-19.6 years old) referred for diagnostic assessments of Autism Spectrum Disorder (ASD) in a…

The purpose of this study was to identify perceptions of environmental changes that promote self-directed learning in the workplace by Human Resources Development (HRD) practitioners and to investigate possible differences of the dependent LPA score variables to independent variables of highest level of education achieved, race/ethnicity, age,…

The automatic evaluation of text-based assessment items, such as short answers or essays, is an open and important research challenge. In this paper, we compare several features for the classification of short open-ended responses to questions related to a large first-year health sciences course. These features include a) traditional n-gram…

Geometrography, "alias the art of geometric constructions" was proposed by Emile Lemoine between the late 1800s and the early 1900s. It consisted originally of a system to measure the complexity of ruler-and-compass geometric constructions, capable of: designate every geometric construction by a pair of values that manifests its…

The current study explored the effect of sexual content in advertisements and the programme-advertisement congruence on the memory of sexual and nonsexual advertisements. Seventy participants (41 females and 29 males) were randomly allocated to one of four conditions. They viewed either "The Bachelorette" (sexual programme) or "I'm…

The Hartung-Knapp method for random-effects meta-analysis, that was also independently proposed by Sidik and Jonkman, is becoming advocated for general use. This method has previously been justified by taking all estimated variances as known and using a different pivotal quantity to the more conventional one when making inferences about the…
