BACKGROUND The methodological quality and completeness of reporting of the systematic reviews (SRs) is fundamental to optimal implementation of evidence-based health care and the reduction of research waste. Methods exist to appraise SRs yet little is known about how they are used in SRs or where there are potential gaps in research best-practice guidance materials. The aims of this study are t...

Adaptationism has prompted many a debate in philosophy of biology but the focus is usually on empirical and explanatory issues rather than methodological adaptationism (MA). Likewise, the context of evolutionary biology has provided the grounding for most discussions of the heuristic role of adaptationism. This paper extends the debate by drawing on case studies from physiology and systems biol...

This is a review essay, based on a critical assessment of The Ant Trap by Brian Epstein. Epstein argues that models in the social sciences are inadequate because they are based on a false ontology of methodological individualism, and proposes a new model of social ontology. I examine this model and point to flaws in it. More generally, I argue against Epstein’s methodological approach, which tr...

BACKGROUND Guidelines for assessing methodological and reporting quality of systematic reviews (SRs) were developed to contribute to implementing evidence-based health care and the reduction of research waste. As SRs assessing a cohort of SRs is becoming more prevalent in the literature and with the increased uptake of SR evidence for decision-making, methodological quality and standard of repo...

PURPOSE To determine the best treatment option for not complicated acute appendicitis (AA) in adult patients, between single incision laparoscopy (SIL) and conventional laparoscopy (CL), measured by morbidity associated with disease. METHODS Systematic review. Articles of adults diagnosed with AA treated by SIL or CL were analyzed. Databases included: MEDLINE, LILACS, IBECS, Web of Science, S...

We provide a taxonomy of the two most important debates in the philosophy of the cognitive and neural sciences. The first debate is over methodological individualism: is the object of the cognitive and neural sciences the brain, the whole animal, or the animal--environment system? The second is over explanatory style: should explanation in cognitive and neural science be reductionist-mechanisti...

Background Epidemiological evidence on the social determinants of health inequity is well-advanced, but considerably less attention has been given to evaluating the impact of public policies addressing those social determinants. Methodological challenges to produce evidence on policy outcomes present a significant barrier to mobilising policy actions for health equities. This review aims to exa...

We review recent developments in the study of culture and personality measurement. Three approaches are described: an etic approach that focuses on establishing measurement equivalence in imported measures of personality, an emic (indigenous) approach that studies personality in specific cultures, and a combined emic-etic approach to personality. We propose the latter approach as a way of combi...

BACKGROUND Gastroenteropancreatic neuroendocrine tumours (GEP-NET) are often slow-growing and patients may live for years with metastasised disease. Hence, along with increasing overall and progression-free survival, treatments aim at preserving patients' well-being and health-related quality of life (HRQoL). However, studies on systematic HRQoL assessment in patients with GEP-NET are scarce. T...

This critical review is mainly concerned with methodological issues in prosody research, with the aim to highlight progress toward developing predictive knowledge about prosody. The review shows that there has been a steady progression in terms of methodological rigor as the field goes through major methodological trends that can be described as analysis-by-introspection, analysis-by-transcript...
