Interest rate policies and inflation in interdependent economies: Recent policy dilemmas

This paper examines Federal Reserve Board policies that are premised on a negative short-run association of interest rate movements and the rate of inflation. In particular, econometric evidence is provided, supporting the view that tighter monetary policy appears to raise inflation rates in the short run. Conversely, it is demonstrated that easier monetary policy does not necessarily raise inflation rates in the short run. In the case of uncoordinated monetary restrictiveness, interest rate competition among major countries can produce higher inflation and lower growth than was originally intended.     

Structural probability bounds for the strong Pareto law

By using the structural density function (Fraser 1979, Ch. 7) of the parameters of a Pareto distribution, the structural distribution function of the strong Pareto law is derived. Its fractiles have been evaluated numerically for special cases, and the results are displayed through graphs from which structural one-sided probability bounds may be found. It is shown that these graphs may also be used to find structural tolerance bounds for the Pareto distribution.     

Estimation of gene/haplotype frequencies in genetic marker systems based on phenotype data

Two equivalent methods (gene counting and maximum likelihood) for estimating gene frequencies in a general genetic marker system based on observed phenotype data are derived. Under the maximum likelihood approach, an expression is given for the estimated covariance matrix from which estimated standard errors of the estimators can be found. In addition, consideration is given to the problem of estimating gene frequencies when there are available several independent population data sets.     

Equity,inclusion, and antiblackness in mathematics education

ABSTRACT

Despite decades of equity- and inclusion-oriented discourse and reform in mathematics education, Black learners in the U.S. continue to experience dehumanizing and violent forms of mathematics education. I suggest that equity for Black learners in mathematics education is a delusion rooted in the fictions of white imaginaries, contingent on appeasing white logics and sensitivities, and characterized at best by incremental changes that do little to threaten the maintenance of racial hierarchies inside or outside of mathematics education. Moreover, the forms of inclusion offered up in equity-oriented discourses and reforms represent contexts of containment and enclosure that keep Black people in their same relative position. Refusal is suggested as a strategy for Black learners to resist the anti-Black character of mathematics education, and as a first step in actualizing forms of mathematics education that are worthy of Black learners.

Educator Sexual Abuse: Two Case Reports

Sexual abuse by educators has become an increasingly noted type of sexual abuse, especially among adolescents, for two reasons. First, there is a potential for these cases to be silent and prolonged and second, when disclosed, the forensic implications usually include both criminal and/or civil sanctions. For forensic case evaluations, developmental traumatology, or the intersection of the traumatic event(s) at a particular age of the student, is often the evaluating framework. We report on two forensic cases of a female student and a male student to emphasize the dynamics of adolescent sexual victimization, its impact on adolescent development, and evidence-based practice for symptom identification and treatment.     

Competitive Capabilities among Manufacturing Plants in Developing,Emerging, and Industrialized Countries: A Comparative Analysis

Competitive capabilities have been defined as a plant's actual performance relative to its competitors, with the most commonly investigated capabilities being quality, delivery, flexibility, and cost. However, most research in this realm has investigated capabilities within developed countries, and neglected the context of developing and emerging nations, which are increasingly becoming viable economic entities in global supply chains in their own right. The present study fills this gap and carries out a comparative analysis of competitive capabilities among plants in developing, emerging, and industrialized countries. Basing our arguments on the resource‐based view of the firm, we suggest that the influence of competitive capabilities on each other varies among plants in differentially industrialized regions. Specifically, we suggest that, on average, competitive capabilities tend to influence each other to a greater degree in plants in emerging and developing countries compared to industrialized countries. Along similar lines, we suggest that the influence of the four competitive capabilities on performance improvement is manifested more strongly among plants in emerging and developing countries than among plants in industrialized nations. We investigate these contentions with data from 1,211 plants in 21 countries. The results are particularly important for decision makers as they decide on the increasingly global location of their manufacturing operations or the configuration of their global supply chains.     

Place,race and differential occupational opportunities

A large body of literature investigating the link between black percentage in the community and occupational differentiation, has found disparities to be greater in places where blacks are in a higher proportion. The present paper discusses first, theoretical perspectives and methodological techniques employed in past research; second, examines the issue in terms of the relative odds of the races for incumbency in a series of occupational groupings; and third, analyzes the effect of percentage black on race-linked occupational differentiation across 124 major American cities. Using log-linear procedures, blacks, relative to whites, are much more likely to be in unskilled and semiskilled manual occupations, while whites, relative to blacks, are far more likely to be in white-collar and upper-status positions. Moreover, blacks' denial of access to higher-status positions, their channeling to lower-status work, and their ability to overflow into specific intermediate-status occupations are found to be greatly influenced both by percentage black as well as other community characteristics. The findings are discussed in light of sociological theories suggesting that the issue cannot be understood solely by the competition hypothesis. One must also consider the overflow and queuing explanations.     

The place of odds ratios in the study of place,race and differential occupational opportunities

Demography - During the last few decades the study of racial differences in occupational and economic attainment has progressed rapidly, both in terms of theory and research. The ecological study...
