Much more than a single theory, realism is a school of thought containing numerous related branches. In recent years an outpour of debate and exchange within the realist tradition has captured the attention of scholars. Many scholars have attempted to create schemes classifying the different branches and threads of realist thought that have emerged, while others have introduced a wealth of new ...

The integration of realist evaluation principles within randomised controlled trials ('realist RCTs') enables evaluations of complex interventions to answer questions about what works, for whom and under what circumstances. This allows evaluators to better develop and refine mid-level programme theories. However, this is only one phase in the process of developing and evaluating complex interve...

BACKGROUND Van Belle et al. argue that our attempt to pursue realist evaluation via a randomised trial will be fruitless because we misunderstand realist ontology (confusing intervention mechanisms with intervention activities and with statistical mediation analyses) and because RCTs cannot comprehensively examine how and why outcome patterns are caused by mechanisms triggered in specific conte...

In this paper, we respond to a paper by Jamal and colleagues published in Trials in October 2015 and take an opportunity to continue the much-needed debate about what applied scientific realism is. The paper by Jamal et al. is useful because it exposes the challenges of combining a realist evaluation approach (as developed by Pawson and Tilley) with the randomised controlled trial (RCT) design....

Ontological realism is a philosophical stance that provides a definitional framework for ontologies and is referred to by various applied ontologists. From a computer science perspective, ontologies are often associated with formal languages for the representation of ontologies like the Web Ontology Language (OWL). It has, however, not been made explicit how the realist framework is related to ...

For more than half a century, realist scholars of international relations have maintained that their world view is inimical to the American public. For a variety of reasons—inchoate attitudes, national history, American exceptionalism—realists assert that the U.S. government pursues realist policies in spite and not because of public opinion. Indeed, most IR scholars share this “anti-realist as...

ing away from the particulars of the example, we now have three countercontexts to threaten the long-term efficacy of incentive programmes, namely: • (C1) budgetary constraints • (C2) alternative usage (exchange utility) • (C3) technical limitations on usage (durability etc.) The next task is to put this primitive little theory to work by considering further examples. Before we do so, it is use...

Despite considerable progress within wilderness and adventure therapy research over the last decade, researchers are still unable to precisely answer why, how, and for whom this treatment modality works. There is also a need for more knowledge regarding the circumstances under which the treatment does not appear to be effective. In this realist synthesis, we attempt to unpack this "black box" o...
