Dementia is a growing public health issue. Activity, a positive therapeutic modality, has potential to enhance quality of life and reduce behavioral symptoms in persons with dementia--outcomes eluding pharmacological treatments. However, it is unclear how to effectively engage persons with dementia in activities for them to derive desired…

The purpose of this study was to explore the use of robust variance estimation for combining commonly specified multiple regression models and for combining sample-dependent focal slope estimates from diversely specified models. The proposed estimator obviates traditionally required information about the covariance structure of the dependent…

Location estimates calculated from heuristic data were examined using traditional and robust statistical methods. The current paper demonstrates the impact outliers have on the sample mean and proposes robust methods to control for outliers in sample data. Traditional methods fail because they rely on the statistical assumptions of normality and…

Vocational education is increasingly seen as a viable path to higher education and not simply a direct route to the labor market. This paper studies the relationship between the secondary school track attended by Chilean students (vocational or academic) and their subsequent outcomes in access to and persistence in postsecondary vocational…

Empirically, the link between classmate ability and individual-level student achievement has been established. And yet, within the scope of this body of literature, there is a dearth of studies examining if a relationship also persists between classmate ability and non-achievement outcomes--that is, social skills. This article fills this research…

The authors analyze matched administrative survey data on economics students enrolled in two econometrics courses offered in consecutive terms at a major public university in Spain to assess the impact of lecture attendance and study time on academic performance. Using proxy variables in a cross-sectional regression setting, they find a positive…

The study had two main aims: (i) to develop a model incorporating research self-efficacy and research disposition as predictors of publication output; and (ii) to assess the fit and robustness of this model to dichotomous groups based on gender, academic qualifications and rank. Data were drawn from a survey of lecturers (n = 331) working in two…

This meta-analysis provides an extensive and organized summary of intervention studies in education that are grounded in motivation theory. We identified 74 published and unpublished papers that experimentally manipulated an independent variable and measured an authentic educational outcome within an ecologically valid educational context. Our…

Many Flynn effect (FE) studies compare scores across different editions of Wechsler's IQ tests. When construct changes are introduced by the test developers in the new edition, however, the presumed generational effects are difficult to untangle from changes due to test content. To remove this confound, we use the same edition of Wechsler…

Purpose: This research uses the social science perspectives of institutions, ecological modernization and social movements to analyze the rationale used by the early-adopting universities of fossil fuel divestment in the USA. Design/methodology/approach: Through analysis of qualitative data from interviews with key actors at the universities that…

Within comparative school effectiveness research facilitated by large-scale data across countries, this article presents the results of the testing for measurement invariance of the latent concept of Professional Community (PC) across 23 European countries and more than 35,000 teachers in secondary schools. The newly proposed Multiple-Group Factor…

University class structure is changing. To accommodate working students, programmes are increasing their offerings of long night classes--some lasting as long as six hours. While these long classes may be more convenient for students, they have unintended consequences as a result of cognitive load. Using a panel of 124 students (372 observations)…

This study uses data on educational expenditure, including specific types of educational expenditure, from the 2009 Socioeconomic Survey of Thailand to investigate gender bias in the allocation of educational resources. Empirical Engel's curves are estimated to test for gender bias. The results show that girls receive more education expenditure…

Replication studies allow for making comparisons and generalizations regarding the effectiveness of an intervention across different populations, versions of a treatment, settings and contexts, and outcomes. One method for making these comparisons across many replication studies is through the use of meta-analysis. A recent innovation in…

Strong school leaders play a vital role in accelerating student achievement across a state. Research has found that principals account for 25 percent of a school's total impact on student achievement, and an above-average principal can raise student achievement by as much as 20 percentage points more than an average principal--equivalent to seven…
