An Extension of the Blinder-Oaxaca Decomposition Technique to Logit and Probit Models AgEcon
Fairlie, Robert W..
The Blinder-Oaxaca decomposition technique is widely used to identify and quantify the separate contributions of group differences in measurable characteristics, such as education, experience, marital status, and geographical differences to racial and gender gaps in outcomes. The technique cannot be used directly, however, if the outcome is binary and the coefficients are from a logit or probit model. I describe a relatively simple method of performing a decomposition that uses estimates from a logit or probit model. Expanding on the original application of the technique in Fairlie (1999), I provide a more thorough discussion of how to apply the technique, an analysis of the sensitivity of the decomposition estimates to different parameters, and the...

Association of acanthosis nigricans with race and metabolic disturbances in obese women BJMBR
Araújo,L.M.B.; Porto,M.V.; Netto,E.M.; Ursich,M.J..
Acanthosis nigricans (AN) has been recognized as a marker of insulin resistance and diabetes mellitus. We have compared frequency of race and metabolic disturbances in obese women with several degrees of AN (AN group, N = 190) to a group without AN (non-AN group, N = 61) from a mixed racial population. The groups were similar regarding age and body mass index. All patients (except the diabetic patients) underwent an oral glucose tolerance test (75 g). The racial distribution of this population was 35.1% white, 37.8% mulatto and 27.1% black and the frequency of AN was 62.5, 82.1 and 83.8%, respectively, higher in black versus white (P = 0.003) and mulatto versus white (P = 0.002) women. The frequencies of diabetes mellitus and impaired glucose tolerance...

El uso de categorías étnico/raciales en censos y encuestas en el Perú: balance y aportes para una discusión AgEcon
Valdivia, Nestor.
En América Latina existe consenso en la necesidad de avanzar hacia la “visibilización” de los grupos indígenas y afrodescendientes para identificar sus problemas y necesidades, brindarles el reconocimiento debido y otorgarles un papel protagónico en las decisiones relacionadas a su propio desarrollo. En este contexto, en los países de la región se ha avanzado en la incorporación de variables étnicas en los censos nacionales y los registros administrativos del Estado. El presente trabajo analiza el caso del Perú y establece un balance de las iniciativas implementadas desde el Estado y el mundo académico para incorporar la dimensión étnica en los instrumentos cuantitativos usados para el análisis de la realidad social peruana. El objetivo de este balance...

Gender, race and socioeconomic influence on diagnosis and treatment of thyroid disorders in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) BJMBR
Olmos,R.D.; Figueiredo,R.C. de; Aquino,E.M.; Lotufo,P.A.; Bensenor,I.M..
Thyroid diseases are common, and use of levothyroxine is increasing worldwide. We investigated the influence of gender, race and socioeconomic status on the diagnosis and treatment of thyroid disorders using data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), a multicenter cohort study of civil servants (35-74 years of age) from six Brazilian cities. Diagnosis of thyroid dysfunction was by thyrotropin (TSH), and free thyroxine (FT4) if TSH was altered, and the use of specific medications. Multivariate logistic regression models were constructed using overt hyperthyroidism/hypothyroidism and levothyroxine use as dependent variables and sociodemographic characteristics as independent variables. The frequencies of overt hyper- and...

Hot spots for diversity of Magnaporthe oryzae physiological races in irrigated rice fields in Brazil. Repositório Alice
DIAS NETO, J. J.; SANTOS, G. R. dos; ANJOS, L. M. dos; RANGEL, P. H. N.; FERREIRA, M. E..
Abstract ? The objective of this work was to evaluate the Magnaporthe oryzae pathotype diversity in new commercial irrigated rice fields in the Araguaia River Valley, state of Tocantins, Brazil. The causal agent of rice blast has heavily affected rice production in the region. Despite the efforts of breeding programs, blast resistance breakdown has been recorded shortly after the release of new resistant cultivars developed for the region. Among the causes of resistance breakage is the capacity of the fungus to rapidly develop new pathotypes. A sample of 479 M. oryzae monosporic isolates was obtained and tested using the international rice blast differential set. Isolate collections were made in small areas designed as trap nurseries and in scattered sites...

Identification of a new race of Hemileia vastratix in Brazil. Repositório Alice
CABRAL, P G. C.; ZAMBOLIM, E. M.; ZAMBOLIM, L.; LELIS, T. P.; CAPUCHO, A. S.; CAIXETA, E. T..
In this study, a survey of physiological races of Hemileia vastatrix was carried out on 34 coffee leaf rust populations collected at several coffee genotypes in Brazil. After the inoculation on leaf disc of coffee differential clones, the races I, II, III, XIII, XVII and XXXVII were characterised. This is the first report of race XXXVII on Coffea arabica in Brazil, which shows the evolutionary potential of H. vastatrix. The emergence of complex races like XXXVII represents a challenge for breeders in the development of resistant cultivars.

Income Convergence in the South: Myth or Reality? AgEcon
Gyawali, Buddhi Raj; Banerjee, Swagata (Ban); Hill, Anquinette; Bukenya, James O..
County-level data for 11 southern states for 1980 and 2000 are used to examine income convergence. Ordinary least squares regression of logarithmic difference on average per capita income in 1980 demonstrated conditional income convergence with higher income changes in counties with smaller initial populations, smaller changes in African Americans, employment, education, age structure, travel time to work, or dependent age populations. The estimated rate of income convergence was 3.82% per year.

Race, Equity, and Public Schools in Post-Apartheid South Africa: Is Opportunity Equal for All Kids? AgEcon
Yamauchi, Futoshi.
This paper examines dynamic changes in educational quality and equity differences in the public school system between Black and other racial groups in post-apartheid South Africa, using the ratio of learners to educators in each school, available from the School Register of Needs, 1996 and 2000. The analysis incorporates school-and community-level unobservables and the endogenous movement of learners. This paper shows that (1) the learner-educator ratios significantly differ between formerly Black and White primary and secondary schools in 1996 and 2000, and (2) in the adjustment of educators in response to changes in the number of learners in this period, there are significant differences between formerly Black and non-Black (White, Coloured, and Indian)...

THE DETERMINANTS OF HAPPINESS AMONG RACE GROUPS IN SOUTH AFRICA AgEcon
Ebrahim, Amina.
This paper tests for happiness differences among race groups in South Africa and also investigates the determinants of happiness for each race group. Using data from the 2008 National Income Dynamics Survey, the results indicate that reported happiness differs substantially among race groups, with Blacks being the least happy. The determinants of happiness also differ between race groups. While Whites attached greater importance to physical health, employment status and absolute income matter greatly for Blacks. For Coloureds and Blacks, relative income is an important determinant of happiness, with religious importance significantly contributing to the happiness of Indians/Asians.

The fallacy of racial pharmacogenomics BJMBR
Pena,S.D.J..
Personalized pharmacogenomics aims to use individual genotypes to direct medical treatment. Unfortunately, the loci relevant for the pharmacokinetics and especially the pharmacodynamics of most drugs are still unknown. Moreover, we still do not understand the role that individual genotypes play in modulating the pathogenesis, the clinical course and the susceptibility to drugs of human diseases which, although appearing homogeneous on the surface, may vary from patient to patient. To try to deal with this situation, it has been proposed to use interpopulational variability as a reference for drug development and prescription, leading to the development of "race-targeted drugs". Given the present limitations of genomic knowledge and of the tools needed to...

The Racial Saving Gap Enigma: Unraveling the Role of Institutions AgEcon
Belton, Willie; Uwaifo Oyelere, Ruth.
It has been well documented in the literature that ethnicity matters significantly in the determination of savings. In particular, African-American savings lag far behind that of other ethnic groups. Similarly, the literature also provides evidence of the long-lived nature of institutions and the link between institutions and culture. In this paper, we provide an explanation for the savings gap that still exists between African-Americans and White Americans even after accounting for appropriate factors that can lead to savings differentials. We initially provide evidence that the savings gap exists and persist after including several control variables in a regression analysis. We then provide evidence that the persistent gap can not be attributed solely...
