Testing for Granger-causality in quantiles

This paper proposes a consistent parametric test of Granger-causality in quantiles. Although the concept of Granger-causality is defined in terms of the conditional distribution, most articles have tested Granger-causality using conditional mean regression models in which the causal relations are linear. Rather than focusing on a single part of the conditional distribution, we develop a test that evaluates nonlinear causalities and possible causal relations in all conditional quantiles, which provides a sufficient condition for Granger-causality when all quantiles are considered. The proposed test statistic has correct asymptotic size, is consistent against fixed alternatives, and has power against Pitman deviations from the null hypothesis. As the proposed test statistic is asymptotically nonpivotal, we tabulate critical values via a subsampling approach. We present Monte Carlo evidence and an application considering the causal relation between the gold price, the USD/GBP exchange rate, and the oil price.     

The Glocal and Global Studies

Abstract

This article offers an overview of engagements with the glocal and traces the consequences of this research agenda for Global Studies. First, it compares the emergence of the global and the glocal in the literature. It tracks the uneven impact of the business use of the glocal and argues that this genealogy has obscured alternative accounts. Second, it offers a thematic overview of the uses of glocalization in the literature. It highlights publication clusters in specific areas of interdisciplinary interest. It further addresses key criticisms against glocalization. Finally, it explores the vicissitudes of research on glocalization on the scope and definition of Global Studies. Trends in Global Studies appear to move in an opposite direction from the one suggested by glocalization. This could lead to the emergence of a separate field of Glocal Studies, causing further fragmentation in the field.     

Nicholas II — 1868-1918

Recent changes in accreditation standards now require professors to systematically assess whether a teacher candidate actually possesses a “disposition” appropriate to the profession. This new mandate from accreditation bodies is controversial on a number of fronts. As social studies educators in particular, we like to think of ourselves as especially attentive to issues such as individual differences and rights, indoctrination, prejudice, intolerance, freedom of expression, maturation, and the worth of the individual—all of which are potentially raised by the NCATE and NCSS mandates. And as a practical matter, it places new stresses on the role of professors as both mentors and gatekeepers. In this article, two social studies teacher educators provide an overview of current theory and debate regarding dispositions, an assessment of practical problems associated with the accreditation accountability mandates, and—in spite of the persistent problems associated with defining and assessing dispositions—offer one successful model for evaluating teacher candidates’ professional dispositions that has been implemented in a social studies education program.     

Marital Quality,Context, and Interaction: A Comparison of Those Currently Receiving Government Assistance with Those Who Are Not

In this study the marital quality of respondents who were currently receiving government assistance was compared with those who were not. Contextual variables (e.g., gender, age, age at first marriage, religiosity, education, etc.) and interactional variables (i.e., escalating negativity, criticism, negative interpretation, withdrawal) were measured as potential correlates with marital quality. Results indicated that those who received government assistance differed significantly from those who did not on all six indicators of marital quality that were measured and on 8 of 11 contextual variables measured. Findings from this study will help policymakers, therapists, and other helping professionals gain an increased awareness of the needs of these two distinct populations and how to target educational programs to best address those needs.     

After the Honeymoon: The Evolution of Problem Issues in Utah LDS Marriages

The main objective of this study was to extend previous research in the area of longitudinal marital satisfaction by examining how marital issues, including decision-making, activities, affection, conflict, financial matters, stability, and values, changed over the first 5 years of marriage for 242 Utah, Latter-Day-Saint individuals. In addition, this study examined whether change occurs differently for husbands versus wives and for at-risk individuals versus non-risk individuals. The results showed that four marital issues worsened over time (activities, affection, conflict, and stability). Two of the six subscales (activities and affection) were found to differ significantly by gender. In addition, four subscales were significantly different for at-risk couples when compared with non-risk couples (decision-making, activities, conflict, and stability). Limitations and recommendations are discussed.     

Advancing Research on LGBTQ Microaggressions: A Psychometric Scoping Review of Measures

ABSTRACT

Understanding the nature and consequences of LGBTQ microaggressions is critical to fostering equity and wellbeing among sexual and gender minorities. Yet little guidance is available for researchers seeking psychometrically robust measures of subtle LGBTQ slights, invalidations, and insults. To address this gap, we conducted a scoping review of multi-item quantitative measures that included at least one question addressing LGBTQ microaggressions. This article reports the study characteristics and psychometric properties of 27 original measures we identified and their subsequent adaptations. The article concludes with an assessment of strengths and limitations of LGBTQ microaggression measurement, highlighting aspects of measurement innovation on which future researchers can build. As microaggressions remain a powerful and underexplored mechanism of sexual and gender minority oppression, this review will help to both advance methodological quality in this critical research area and enhance our understanding of how microaggressions manifest in the lives of LGBTQ individuals.     

Use of an empirical probability generating function for testing a Poisson model

We present a test of the fit to a Poisson model based on the empirical probability generating function (epgf). We derive the limiting distribution of the test under the Poisson hypothesis and show that a rescaling of it is approximately independent of the mean parameter in the Poisson distribution. When inspected under a simulation study over a range of alternative distributions, we find that this test shows reasonable behaviour compared to other goodness-of-fit tests like the Poisson index of dispersion and smooth test applied to the Poisson model. These results illustrate that epgf-based methods for anlyzing count data are promising.
