Financial liberalization and long-run stability of money demand in Nigeria

A stable money demand function is essential when using monetary aggregate as a monetary policy. Thus, there is need to examine the stability of the money demand function in Nigeria after the deregulation of the financial sector. To achieve this, the study employed CUSUM (cumulative sum) and CUSUMSQ (CUSUM of square) tests after using autoregressive distributive lag bounds test to determine the existence of a long run relationship between monetary aggregates and their determinants. Results of the study show that a long-run relationship holds and that the demand for money is stable in Nigeria. In addition, the inflation rate is found to be a better proxy for an opportunity variable when compared to interest rate. The main implication of the study is that interest rate is ineffective as a monetary policy instrument in Nigeria.     

The Effect of Joint Control Training on the Performance of Multiply Controlled Behavior: A Systematic Literature Review Relevant to Children With Autism Spectrum Disorder and Other Developmental Disabilities

Skinner (1957) differentiated the roles of the speaker and the listener in a verbal encounter. Although not extensively emphasized, Skinner suggested an individual often behaves verbally even when responding as a listener. Children diagnosed with autism spectrum disorders (ASD) often display the absence of important, and basic verbal repertoires that limit their ability to engage in a variety of social skills or problem-solving skills. Joint control suggests that multiply controlled verbal responding involves functional control of two 2 or more stimuli or verbal operants. This systematic literature review provides a summary of publications specifying the relation and implications of the analysis of joint control and joint control training in the acquisition of multiply controlled, non-speaker behaviors (e.g., selection-based behavior; , sequencing behavior). The synthesis suggests that joint control training presents as a promising analytic tool in guiding interventions to teach complex, multiply controlled verbal and non-verbal repertoires to children diagnosed with autism ASD and/or other developmental disabilities. Recommendations for future research in joint control, as well as the implementation of joint control training, are provided.

     

Positive affect regulation in youth: Taking stock and moving forward

This article summarizes the four articles in the Social Development quartet focused on positive affect regulation in youth. Each article in the quartet shows that parents’ socialization of youth positive affect (e.g., encouraging, enhancing, savoring, or dampening responses) is associated with youth positive affect regulation and depressive symptoms. Further, three of the studies provide novel evidence for an indirect relationship whereby parental socialization predicts youth depressive symptoms through youth positive affect regulation. The studies include samples of youth across mid‐childhood and adolescence (7–18‐year‐olds) from three countries (the United States, Belgium, and India), and utilize several methods of assessing youth positive affect regulation or parental socialization (parent‐reported surveys, youth‐reported surveys, coded parent–child discussions). This integrative article also identifies several ways in which the study of youth positive affect regulation can be advanced. We address the conceptualization of positive affect regulation and the socialization of children's positive affect, constraints on the adaptiveness of upregulating positive emotions, methodological directions, potential moderated effects based on child characteristics such as sex or temperament, and the importance of studying outcomes beyond depression.     

Building a Human Health Risk Assessment Ontology (RsO): A Proposed Framework

Over the last decade the health and environmental research communities have made significant progress in collecting and improving access to genomic, toxicology, exposure, health, and disease data useful to health risk assessment. One of the barriers to applying these growing volumes of information in fields such as risk assessment is the lack of informatics tools to organize, curate, and evaluate thousands of journal publications and hundreds of databases to provide new insights on relationships among exposure, hazard, and disease burden. Many fields are developing ontologies as a way of organizing and analyzing large amounts of complex information from multiple scientific disciplines. Ontologies include a vocabulary of terms and concepts with defined logical relationships to each other. Building from the recently published exposure ontology and other relevant health and environmental ontologies, this article proposes an ontology for health risk assessment (RsO) that provides a structural framework for organizing risk assessment information and methods. The RsO is anchored by eight major concepts that were either identified by exploratory curations of the risk literature or the exposure‐ontology working group as key for describing the risk assessment domain. These concepts are: (1) stressor, (2) receptor, (3) outcome, (4) exposure event, (5) dose‐response approach, (6) dose‐response metric, (7) uncertainty, and (8) measure of risk. We illustrate the utility of these concepts for the RsO with example curations of published risk assessments for ionizing radiation, arsenic in drinking water, and persistent pollutants in salmon.     

On An Intriguing Distributional Identity

For a continuous random variable X with support equal to (a, b), with c.d.f. F, and g: Ω₁ → Ω₂ a continuous, strictly increasing function, such that Ω₁∩Ω₂?(a, b), but otherwise arbitrary, we establish that the random variables F(X) ? F(g(X)) and F(g^{? 1}(X)) ? F(X) have the same distribution. Further developments, accompanied by illustrations and observations, address as well the equidistribution identity U ? ψ(U) = ^dψ^{? 1}(U) ? U for U ～ U(0, 1), where ψ is a continuous, strictly increasing and onto function, but otherwise arbitrary. Finally, we expand on applications with connections to variance reduction techniques, the discrepancy between distributions, and a risk identity in predictive density estimation.     

Deep Uncertainties in Sea-Level Rise and Storm Surge Projections: Implications for Coastal Flood Risk Management

Sea levels are rising in many areas around the world, posing risks to coastal communities and infrastructures. Strategies for managing these flood risks present decision challenges that require a combination of geophysical, economic, and infrastructure models. Previous studies have broken important new ground on the considerable tensions between the costs of upgrading infrastructure and the damages that could result from extreme flood events. However, many risk-based adaptation strategies remain silent on certain potentially important uncertainties, as well as the tradeoffs between competing objectives. Here, we implement and improve on a classic decision-analytical model (Van Dantzig 1956) to: (i) capture tradeoffs across conflicting stakeholder objectives, (ii) demonstrate the consequences of structural uncertainties in the sea-level rise and storm surge models, and (iii) identify the parametric uncertainties that most strongly influence each objective using global sensitivity analysis. We find that the flood adaptation model produces potentially myopic solutions when formulated using traditional mean-centric decision theory. Moving from a single-objective problem formulation to one with multiobjective tradeoffs dramatically expands the decision space, and highlights the need for compromise solutions to address stakeholder preferences. We find deep structural uncertainties that have large effects on the model outcome, with the storm surge parameters accounting for the greatest impacts. Global sensitivity analysis effectively identifies important parameter interactions that local methods overlook, and that could have critical implications for flood adaptation strategies.     

Feminist Christian Realism

While Christianity and feminism may seem at odds with one another, both make normative claims about justice and addressing the needs of those on the margins of power. This article explores what feminism contributes to Christian realism. The current revival of Niebuhrian Christian realism highlights how much it still has to offer as a theoretical underpinning for policy and governance. However, Christian realism remains wedded to masculinist abstractions and power structures, such as the balance of power, that are ultimately harmful to those on the margins. Thus, this article uses feminism to argue for a greater acceptance of vulnerability and obligation in Christian realism.
