Experimental research scholars often discretize quantitative variables when testing moderation. This pedagogical article addresses the limitations of this approach and considers when and how spotlight and floodlight analyses should be used depending on whether the moderating variable at stake...

A large body of work has documented significant educational delays and other challenges among children in foster care. In response, child welfare agencies have developed different policies and practices to help monitor, support, and advocate for foster children's educational needs. An important...

This paper formalizes the design of experiments intended specifically to study spillover effects. By first randomizing the intensity of treatment within clusters and then randomly assigning individual treatment conditional on this cluster-level intensity, a novel set of treatment effects can be...

In this work, new halophyte plant biomass is proposed as raw material for bioenergy production. The bioconversion process of lignocellulosic materials into ethanol needs a pretreatment before enzymatic hydrolysis of vegetal material to increase the yield of fermentable sugars. Various mechanical...

Dengue is the most rapidly spreading mosquito-borne viral disease in the world (WHO, 2009). During the last two decades, the dramatic rise in the number of dengue infections has been particularly evident in Latin American and the Caribbean countries. This paper examines the experimental evidence...

A methodology is developed to add runs to existing supersaturated designs. The technique uses information from the analysis of the initial experiment to choose the best possible follow-up runs. After analysis of the initial data, factors are classified into one of three groups: primary,...

Throughout the 1970s, a “no-fault revolution” swept through the United States, reducing the legal and economic barriers to divorce. Previous studies have found that these legal changes did at least temporarily increase divorces, and may have been, on average, detrimental to women’s...

Evolutionary theory, developmental systems theory, and evolutionary epistemology provide deep theoretical foundations for understanding programs, their development over time, and the role of evaluation. This paper relates core concepts from these powerful bodies of theory to program evaluation....
