Multivariate Meta-Analysis as Structural Equation Models

Multivariate meta-analysis has become increasingly popular in the educational, social, and medical sciences. It is because the outcome measures in a meta-analysis can involve more than one effect size. This article proposes 2 mathematically equivalent models to implement multivariate meta-analysis in structural equation modeling (SEM). Specifically, this article shows how multivariate fixed-, random- and mixed-effects meta-analyses can be formulated as structural equation models. metaSEM (a free R package based on OpenMx) and Mplus are used to implement the proposed procedures. A real data set is used to illustrate the procedures. Formulating multivariate meta-analysis as structural equation models provides many new research opportunities for methodological development in both meta-analysis and SEM. Issues related to and extensions on the SEM-based meta-analysis are discussed.     

The Empire Writes Back…Back: Postcolonial Studies in an Age of Autogenic War

This essay attempts to disclose a uniquely volatile nexus that implicates – and perhaps, reinvigorates – a postcolonial analytics of insurgency. This nexus includes three strands of inquiry: the first is the so-called Revolution in Military Affairs (RMA), which really is – albeit in a qualified sense – revolutionary. War is doing new things with time and space through culture, media, and data technology, and in the process is mutating not only what it means to be a part of this or that national group but is also changing what it means to be human. The second strand of inquiry focuses on the legacy of postcolonial studies, particularly the notion of ‘writing back’ which, I contend, is an apposite starting point for writing critically about the RMA. Apposite though it is, there are limits to postcolonial studies in the contemporary war context. This is so because while the divisions of individual difference are shifting, the coherence of the nation state itself is undergoing radical change. Moving outward in scope to a planetary scale, the human being per se is no longer a primary category by and for which war is happening today. Thus the third strand of inquiry is focused on the residual anthropomorphic tendencies within postcolonial studies that too narrowly limit discussions of violence and collective belonging. The concept of the human being per se remains reliant on early models of technology and media (namely, writing and literature, usually novels). Therefore, in the context of an ever-expanding global war machine, ‘writing back’ is a concept that requires fine-tuning and revision.     

Politics,Paradoxes and Pragmatics of Happiness

European leaders and the popular media have shown a new-found interest in happiness as a socio-political value and goal. A growing body of research attempts to identify the conditions under which humans experience the highest levels of happiness, life-satisfaction or subjective well-being. This essay examines what makes a contemporary science and politics of happiness possible by taking a critical look at such efforts to define, measure and promote happiness, while seeking out a range of diverging, often paradoxical, cultural discourses of happiness. The essay covers the following themes: happiness is attainable; happiness is lost; happiness is obligatory; happiness is impossible; and, happiness is inauthentic. The essay critically examines political uses of the word happiness, disrupting received opinions about this contested term.     

The art and artifice of early sports photography

Abstract

The rise of modern sport in the mid-nineteenth century coincided with the emergence of photography as a new image-making medium. Thus, both practices developed in parallel. Notably, many early photographers turned to sport as a subject for their work, despite the early technological limitations of the medium. Histories of photography have, however, tended to overlook this. Similarly, sport historians have tended to regard these early photographs simply as illustrative material rather than important innovations in the formation of new visual conventions for the representation of sport. This paper seeks to redress this by exploring, in close detail, examples of sports photography produced in the mid- to late-nineteenth century. More importantly, it examines the visual vocabularies deployed by these early photographers within the context of contemporary art practices, demonstrating how artistry and artifice were deployed in the production of some of the earliest, and finest, examples of sports photography ever produced.     

Validation of the swimming competence questionnaire for children

ABSTRACT

Two studies were employed to test the reliability and validity of the Swimming Competence Questionnaire (SCQ) among primary school children. Study 1 was a cross-sectional survey in 4959 primary school children. Study 2 was a pre-post-test quasi-experiment among 1609 primary school children who underwent a 20-lesson learn-to-swim programme. In Study 1, exploratory structural equation modelling revealed excellent goodness-of-fit and scale reliability for a two-factor model comprising distance and skill factors, which supported the construct and convergent validity. SCQ scores were significantly and positively correlated with swimming outcomes (i.e., self-efficacy, intention, swimming frequency), which supported SCQ’s concurrent and criterion validity. Average variance extracted for the SCQ factors exceeded cut-off criteria supporting discriminant validity. In Study 2, pre-test SCQ scores correlated significantly and positively with the SCQ scores, self-efficacy, intention, and swimming frequency at post-test, which supported SCQ’s test-retest reliability and predictive validity. Positive intraclass correlation between SCQ scores and coach ratings at post-test provided evidence for SCQ’s inter-rater reliability. SCQ scores significantly improved at post-test, which supported SCQ’s ecological validity. In conclusion, findings indicate that the SCQ is a valid and reliable measure to assess primary school children’s swimming competence, in terms of swimming distance and basic water survival skills.     

Co-existing Notions of Research Quality: A Framework to Study Context-specific Understandings of Good Research

Minerva - Notions of research quality are contextual in many respects: they vary between fields of research, between review contexts and between policy contexts. Yet, the role of these co-existing...
