BACKGROUND There is a growing body of evidence on the risks and benefits of influenza vaccination in various target groups. Systematic reviews are of particular importance for policy decisions. However, their methodological quality can vary considerably. OBJECTIVES To investigate the methodological quality of systematic reviews on influenza vaccination (efficacy, effectiveness, safety) and to...

Arguments derived from the theory of science have been present in strategic management discourse since at least the beginning of the 1970s. The field’s topjournal, the Strategic Management Journal, has printed several theory of sciencebased papers. Most positions in the theory of science (falsificationism, instrumentalism, realism, constructivism, etc.) have been present in the methodological d...

In this short essay we respond to Jepperson and Meyer’s (2011) critique of “action theories” and methodological individualism in sociology. We highlight fundamental problems with their argument, notably their misconception of methodological individualism(s) and the belief that this explanatory principle ignores—and is somehow invalidated by—the complex, “emergent” and multi-level nature of soci...

Most insights of environmental economics are in line with the standard neoclassical economic model of rational behaviour, formulated in terms of maximization of utility in general, or of profits in particular. The standard theory of environmental policy is a case in point. However, the maximization hypothesis and its methodological foundation have been criticized on many grounds related to a la...

2009 marks the centenary of methodological individualism (MI). The phrase was first used in English in a 1909 QJE paper by Joseph Schumpeter.

MI is often invoked as a fundamental description of the methodology both of neoclassical and Austrian economics, as well as other approaches, from New Keynesianism to analyti...

Post-licensure real world evaluation of vaccine implementation is important for establishing evidence of vaccine effectiveness (VE) and programme impact, including indirect effects. Large cohort studies offer an important epidemiological approach for evaluating VE, but have inherent methodological challenges. Since March 2012, we have conducted an open prospective cohort study in two sites in r...

UNLABELLED A new form of literature review has emerged, Mixed Studies Review (MSR). These reviews include qualitative, quantitative and mixed methods studies. In the present paper, we examine MSRs in health sciences, and provide guidance on processes that should be included and reported. However, there are no valid and usable criteria for concomitantly appraising the methodological quality of t...

Asking children and adolescents directly about their experience of sexual victimization overcomes some of the methodological weaknesses inherent in other approaches. Yet complex legal, ethical, and methodological issues remain. This paper reviews the psychometric properties of those questions or instruments that have measured exposure to child sexual abuse directly. A search of four electronic ...

Game theory has been used to model large-scale social events—such constitutional law, democratic stability, standard setting, gender roles, social movements, communication, markets, the selection of officials by means of elections, coalition formation, resource allocation, distribution of goods, and war—as the aggregate result of individual choices in interdependent decision-making. Game theory...
