It is broadly acknowledged that, for quality management to be effective, it needs to be viewed and implemented as a dynamic and active process by people in an organisation, specifically its leaders. This study aimed to determine the level of leaders' commitment with regard to their perceptions and attitudes concerning quality management of…

This study investigated the systematic rise in cognitive ability scores over generations, known as the "Flynn Effect," across middle childhood and early adolescence (7-15 years; 291 monozygotic pairs, 298 dizygotic pairs; 89% White). Leveraging the unique structure of the Louisville Twin Study (longitudinal data collected continuously…

Face-processing deficits, while not required for the diagnosis of autism spectrum disorder (ASD), have been associated with impaired social skills--a core feature of ASD; however, the strength and prevalence of this relationship remains unclear. Across 445 participants from the NIMH Data Archive, we examined the relationship between Benton Face…

Educational large-scale assessments (LSAs) often provide plausible values for the administered competence tests to facilitate the estimation of population effects. This requires the specification of a background model that is appropriate for the specific research question. Because the "German National Educational Panel Study" (NEPS) is…

Purpose: Children with a developmental language disorder (DLD) are often delayed in their grammatical development. This is suggested to be the most important characteristic and clinical marker of DLD. However, it is unknown if this assumption is valid for young children, in the earliest stages of grammatical development. For this reason, this…

This study described exceptional items in human figure drawings (HFDs) which have been discussed as possible expressions of intellectual giftedness. The aim was to serve as a first step in the development of a screener for HFDs that can be used as part of the identification process of gifted children. We examined the frequency of occurrence of 158…

Purpose: This study sought to determine the minimally detectable change (MDC) of sentence intelligibility for speakers with multiple sclerosis (MS) and Parkinson's disease (PD). Method: Speakers included 78 participants consisting of 32 neurologically healthy control speakers, 30 speakers with MS, and 16 speakers with PD. All speakers were…

Intensive longitudinal data is increasingly used to study state-like processes such as changes in daily stress. Measures aimed at collecting such data require the same level of scrutiny regarding scale reliability as traditional questionnaires. The most prevalent methods used to assess reliability of intensive longitudinal measures are based on…

"Viva voce" or oral examinations are an intrinsic part of the examination of many doctoral theses. There is some ambiguity about their purpose; however, they are generally perceived to be an opportunity for the candidate to respond to the examiners' comments and questions. They also allow examiners to assure themselves of the candidate's…

The application of student response systems could have a lesser effect on the science education of younger students compared to the effects achieved with older students in language and social science courses. The aim of this research was to determine the effect of the application of Kahoot and Quizizz on the academic achievement of third grade…

This study examined the relationship between parental involvement in education (PIE) and adolescent academic achievement in 99 adolescents with and without ADHD. PIE was measured by two parent-report questionnaires. A standardized test was used to measure academic achievement. Adolescent ADHD status predicted academic achievement. Maternal PIE did…

Equating methods are designed to adjust between alternate versions of assessments targeting the same content at the same level, with the aim that scores from the different versions can be used interchangeably. The statistical processes used in equating have, however, been extended to statistically "link" assessments that differ, such as…

In recent years, students' performance in Biology in the Senior Secondary Certificates Examination (SSCE) has not been encouraging. Studies have attributed fluctuating achievement of students in Biology to ineffective use of instructional strategies. If sustainable solution is not proffered to the issue of poor performance in Biology, it could…

Novel tests of semantic memory (SM)--for example, memory for news events (NE; news facts) or famous personalities--are useful for estimating the severity of retrograde amnesia. Individuals with mild cognitive impairment exhibit relatively intact SM/language on traditional neuropsychological tests but exhibit consistent impairment on novel tests of…

When constructed-response items are administered for a second time, it is necessary to evaluate whether the current Time B administration's raters have drifted from the scoring of the original administration at Time A. To study this, Time A papers are sampled and rescored by Time B scorers. Commonly the scores are compared using the proportion of…
