This study determines the prevalence of bullying and the variables that explain the phenomenon in adolescents from educational institutions in Medellín. A survey involving school climate, family functionality, and bullying was applied in a representative sample of 3,460 adolescents. The information was analyzed with descriptive measures, Z-test,…

Competition judges are often selected for their expertise, under the belief that a high level of performance expertise should enable accurate judgments of the competitors. Contrary to this assumption, we find evidence that expertise can reduce judgment accuracy. Adaptation level theory proposes that discriminatory capacity decreases with greater…

A simulation study is presented to evaluate and compare three methods to estimate the variance of the estimates of the parameters d and "C" of the signal detection theory (SDT). Several methods have been proposed to calculate the variance of their estimators, "d'" and "c." Those methods have been mostly assessed by…

Humans are motivated to connect with others and are sensitive to social exclusion--intentionally leaving out others. This ability to detect social exclusion is suggested to be evolutionarily adaptive, biologically hardwired, and an important feature of social-cognitive development. Yet it is unclear when children start to independently detect…

Synthesizing results from multiple studies is a daunting task during which researchers must tackle a variety of challenges. The task is even more demanding when studying developmental processes longitudinally and when different instruments are used to measure constructs. Data integration methodology is an emerging field that enables researchers to…

The relationship between ethnic socialization by parents, peers, and ethnic identity development was examined over a 7-year time span in a sample of 116 internationally adopted Korean American adolescents. Parent report data was collected in 2007 (Time 1 [T1]) when the adopted child was between 7 and 13 years old and again in 2014 at ages 13 to 20…

The ability to interpret graphs is highly important in modern society, but has proven to be a challenge for many people. In this paper, two teaching methods were used to remediate one specific misinterpretation: the area misinterpretation of box plots. First, we used refutational text to explicitly state and invalidate the area misinterpretation…

With the ease and automation of data collection and plummeting storage costs, organizations are faced with massive amounts of data that present two pressing challenges: technical analysis of the data themselves and communication of the analytics process and its products. Although a plethora of academic and practitioner literature have focused on…

The aim of the study is to examine undergraduate students' awareness of metacognition, the metacognitive strategies they use in their learning and their learning performance in pre-class asynchronous activity in a flipped classroom. The sample consisted of 47 undergraduate students. Eleven students were not included in this study since they did…

An undersupply of generalists doctors in rural communities globally led to widening participation (WP) initiatives to increase the proportion of rural origin medical students. In 2002 the Australian Government mandated that 25% of commencing Australian medical students be of rural origin. Meeting this target has largely been achieved through…

Purpose: We examine the impact of advice given by extension agents to Ethiopian farmers, as perceived by the farmers themselves. Design/methodology/approach: Using survey data from 2014, we analyze the perceived impact of advice on farmers' incomes and crop yields. We use a bootstrapped instrumental variable (IV) estimator and the conditional…

The recently proposed Social Motivation theory (Chevallier et al., Trends in cognitive sciences 16(4):231-239, 2012) suggests that social difficulties in Autism Spectrum Condition (ASC) might be caused by a difference in the motivation to engage with other people. Here we compared adolescents with (N = 31) and without (N = 37) ASC on the…

This study was an attempt to investigate the functions of personal metadiscursive expressions found in academic monologues and dialogues. The analysis was based on verbal data of 16 academic lectures and discussions. Based on Ädel's (2010) taxonomy of the subtypes and discourse functions of metadiscourse, the two data sets were compared in terms…

This study investigated the suitability of the FIT-Choice scale for use within an Irish Initial Teacher Education setting with a cohort of first year pre-service teachers (n = 143), from across five different subject disciplines. Exploratory factor analyses were conducted to examine participants' motivations for choosing teaching as a career, as…

Previous studies showing that Autism Spectrum Disorder (ASD) in children can have secondary effects on the child's parents are limited by small sample sizes and parent self-report. We examined the odds of depression in parents of children with ASD compared to parents of children without ASD using a large national claims database. Mothers (OR 2.95,…
