Using intersectionality to change how psychologists think about the demographic profile of their participants is one readily available change that psychologists across the discipline can implement to improve psychological science. In this article, we aim to provide a guide for psychologists who are not already engaged with feminist practices and/or are unsure of how an intersectional approach to participants applies to their research. We argue that by engaging with four perspective shifts of intersectional thinking: multidimensionality, dynamic construction, structural power, and outcomes of systemic disadvantage and advantage, psychologists can more accurately represent the “person” that psychology, as a discipline, seeks to understand. We suggest changes at the researcher, journal, and grant-making agency levels to support an intersectional reconceptualization of participants. As psychology continues to change, in order to foster reproducible science practices and research with relevance to real-world problems, there is opportunity to promote discipline-level change that would take intersectionality seriously.

AbstractIf we want psychological science to have a meaningful real-world impact, it has to be trusted by the public. Scientific progress is noisy; accordingly, replications sometimes fail even for true findings. We need to communicate the acceptability of uncertainty to the public and our peers, to prevent psychology from being perceived as having nothing to say about reality.

The Taylor Aggression Paradigm (TAP) is a frequently-used laboratory measure of aggressive behavior. However, the flexibility inherent in its implementation and analysis can undermine its validity. To test whether the TAP was a valid aggression measure irrespective of this flexibility, I conducted a preregistered study of a 25-trial version of the TAP using a single scoring approach with 160 diverse undergraduate participants. TAP scores showed agreement with other laboratory aggression measures and were magnified by an experimental provocation manipulation. Mixed evidence was found for associations with aggressive dispositions and real-world violence. These results provide preliminary support for this approach to the TAP to measure state-level aggressive behavior. However, more evidence is needed to assess the TAP’s external validity and ability to measure dispositional forms of aggression. Using preregistered designs, researchers should validate specific variants of their behavioral tasks in order to optimize the veridicality and reproducibility of psychological science.

The socio-environmental challenges the world faces are ‘swamps’: situations that are messy, complex, and uncertain. The aim of this paper is to help disciplinary scientists navigate these swamps. To achieve this, the paper evaluates an integrative framework designed for researching complex real-world problems, the Integration and Implementation Science (i2S) framework. As a pilot study, we examine seven inter and transdisciplinary agri-environmental case studies against the concepts presented in the i2S framework, and we hypothesise that considering concepts in the i2S framework during the planning and delivery of agri-environmental research will increase the usefulness of the research for next users. We found that for the types of complex, real-world research done in the case studies, increasing attention to the i2S dimensions correlated with increased usefulness for the end users. We conclude that using the i2S framework could provide handrails for researchers, to help them navigate the swamps when engaging with the complexity of socio-environmental problems.

This paper presents two-person games involving optimal stopping. As far as we are aware, the type of problems we study are new. We confine our interest to such games in discrete time. Two players are to chose, with randomised choice-priority, between two games G1 and G2. Each game consists of two parts with well-defined targets. Each part consists of a sequence of random variables which determines when the decisive part of the game will begin. In each game, the horizon is bounded, and if the two parts are not finished within the horizon, the game is lost by definition. Otherwise the decisive part begins, on which each player is entitled to apply their or her strategy to reach the second target. If only one player achieves the two targets, this player is the winner. If both win or both lose, the outcome is seen as “deuce”. We motivate the interest of such problems in the context of real-world problems. A few representative problems are solved in detail. The main objective of this article is to serve as a preliminary manual to guide through possible approaches and to discuss under which circumstances we can obtain solutions, or approximate solutions.

This book is on algorithms for network flows. Network flow problems are optimization problems where given a flow network, the aim is to construct a flow that respects the capacity constraints of the edges of the network, so that incoming flow equals the outgoing flow for all vertices of the network except designated vertices known as the source and the sink. Network flow algorithms solve many real-world problems. This book is intended to serve graduate students and as a reference. The book is also available in eBook (ISBN 9781316952894/US$ 32.00), and hardback (ISBN 9781107185890/US$99.99) formats. The book has a companion web site www.networkflowalgs.com where a pre-publication version of the book can be downloaded gratis.
