Recently, the development of the constraint-based framework of optimality theory has been adopted and applied to the assessment and treatment of children with phonological disorders. This paper provides a demonstration of the application of optimality theory to the assessment and treatment of a single child with a phonological disorder. First, a tutorial of the theory is provided. Then, several prototypical error patterns evident in the child's productions are analyzed within the framework. These errors are accounted for by assuming that constraints against marked structure are ranked over constraints that require faithfulness to input forms within the child’s grammar. Following that, a demonstration of how optimality theory accounts for different types of variation in the child’s productions is provided. These different types of variation are revealing of the true nature of certain error patterns, particularly an apparent pattern of cluster reduction. Finally, the results of the analysis lead to suggestions for treatment that focus on the demotion of markedness constraints below faithfulness constraints.

This paper presents a case study of a Jordanian child with phonological speech disorders. It seeks to investigate functional phonological disorders and their treatment among Jordanian children within an Optimality Theoretic (OT) perspective. It aims to provide treatment for children’s speech errors within a constraint-based system. The analysis of the data identifies seven error patterns in the child’s productions, namely: fronting, lateralization, stopping, devoicing, de-emphasization, syllable deletion and cluster reduction. Furthermore, OT is employed at the end of the study as a guideline to select the priority of treatment goals by demoting responsible markedness constraints below faithfulness constraints.

This tutorial presents an introduction to the contemporary linguistic framework known as optimality theory (OT). The basic assumptions of this constraint-based theory as a general model of grammar are first outlined, with formal notation being defined and illustrated. Concepts unique to the theory, including “emergence of the unmarked,” are also described. OT is then examined more specifically within the context of phonological acquisition. The theory is applied in descriptions of children's common error patterns, observed inter- and intrachild variation, and productive change over time. The particular error patterns of fronting, stopping, final-consonant deletion, and cluster simplification are considered from an OT perspective. The discussion concludes with potential clinical applications and extensions of the theory to the diagnosis and treatment of children with functional phonological disorders.

My response to Fey’s article (1985; reprinted 1992, this issue) focuses on the confusion caused by the application of simplistic phonological definitions and models to the assessment and treatment of children with speech delays. In addition to having no explanatory adequacy, such definitions/models lead either to assessment and treatment procedures that are similarly focused or to procedures that have no clear logical ties to the models with which they supposedly are linked. Narrowly focused models and definitions also usually include no mention of speech production processes. Bemoaning this state of affairs, I attempt to show why it is important for clinicians to embrace broad-based models of phonological disorders that have some explanatory value. Such models are consistent with assessment procedures that are comprehensive in nature and treatment procedures that focus on linguistic, as well as motoric, aspects of speech.

Abstract. In this paper, we report the results of a study of English speakers who have learned Spanish as a second language. All were late learners who have achieved near- advanced proficiency in Spanish. The focus of the research is on the production of subject-verb agreement errors and the factors that influence the incidence of such errors. There is some evidence that English and Spanish subject-verb agreement differ in susceptibility to interference from different types of variables; specifically, it has been reported that Spanish speakers show a greater influence of semantic factors in their implementation of subject-verb agreement ( Vigliocco, Butterworth, & Garrett, 1996 ). In our study, all participants were tested in English (L1) and Spanish (L2). Results indicate nearly identical error patterns: these speakers show no greater influence of semantic variables in the computation of agreement when they are speaking Spanish than when they are speaking English.

Natural resource managers need up-to-date information about how people interact with public lands and the meanings these places hold for use in planning and decision-making. This case study explains the use of public participatory Geographic Information System (GIS) to generate and analyze spatial patterns of the uses and values people hold for the Browns Canyon National Monument in Colorado. Participants drew on maps and answered questions at both live community meetings and online sessions to develop a series of maps showing detailed responses to different types of resource uses and landscape values. Results can be disaggregated by interaction types, different meaningful values, respondent characteristics, seasonality, or frequency of visit. The study was a test for the Bureau of Land Management and US Forest Service, who jointly manage the monument as they prepare their land management plan. If the information generated is as helpful throughout the entire planning process as initial responses seem, this protocol could become a component of the Bureau’s planning tool kit.


The effective altruism movement consists of a growing global community of people who organize significant parts of their lives around two key ideas, represented in its name. Altruism: If we use a significant portion of the resources in our possession—whether money, time, or talents—with a view to helping others, we can improve the world considerably. Effectiveness: When we do put such resources to altruistic use, it is crucial to focus on how much good this or that intervention is reasonably expected to do per unit of resource expended (for example, per dollar donated). While global poverty is a widely used case study in introducing and motivating effective altruism, if the ultimate aim is to do the most good one can with the resources expended, it is far from obvious that global poverty alleviation is highest priority cause area. In addition to ranking possible poverty-alleviation interventions against one another, we can also try to rank interventions aimed at very different types of outcome against one another. This includes, for example, interventions focusing on animal welfare or future generations. The scale and organization of the effective altruism movement encourage careful dialogue on questions that have perhaps long been there, throwing them into new and sharper relief, and giving rise to previously unnoticed questions. In the present volume, the first of its kind, a group of internationally recognized philosophers, economists, and political theorists contribute in-depth explorations of issues that arise once one takes seriously the twin ideas of altruistic commitment and effectiveness.

In recent years, the field of clinical psychology has seen a growing movement toward the research and development of transdiagnostic treatments. Transdiagnostic approaches have the potential to address numerous issues related to the development and treatment of mental disorders. Among these are the high rates of comorbidity across disorders, the increasing need for efficient protocols, and the call for treatments that can be more easily disseminated. This chapter provides a review of the current transdiagnostic treatment approaches for the treatment of youth mental disorders. Three different types of transdiagnostic protocols are examined: mechanism-based protocols, common elements treatments, and general treatment models that originated from single-disorder approaches to have broader reach. A case study illuminates how a mechanism-based approach would inform case conceptualization for a client presenting with internalizing and externalizing symptoms and how a transdiagnostic framework translates into practice.

Structural geological models are widely used to represent relevant geological interfaces and property distributions in the subsurface. Considering the inherent uncertainty of these models, the non-uniqueness of geophysical inverse problems, and the growing availability of data, there is a need for methods that integrate different types of data consistently and consider the uncertainties quantitatively. Probabilistic inference provides a suitable tool for this purpose. Using a Bayesian framework, geological modeling can be considered as an integral part of the inversion and thereby naturally constrain geophysical inversion procedures. This integration prevents geologically unrealistic results and provides the opportunity to include geological and geophysical information in the inversion. This information can be from different sources and is added to the framework through likelihood functions. We applied this methodology to the structurally complex Kevitsa deposit in Finland. We started with an interpretation-based 3D geological model and defined the uncertainties in our geological model through probability density functions. Airborne magnetic data and geological interpretations of borehole data were used to define geophysical and geological likelihoods, respectively. The geophysical data were linked to the uncertain structural parameters through the rock properties. The result of the inverse problem was an ensemble of realized models. These structural models and their uncertainties are visualized using information entropy, which allows for quantitative analysis. Our results show that with our methodology, we can use well-defined likelihood functions to add meaningful information to our initial model without requiring a computationally-heavy full grid inversion, discrepancies between model and data are spotted more easily, and the complementary strength of different types of data can be integrated into one framework.
