Export agriculture is feeding malaria: a cross-national examination of the environmental and social causes of malaria prevalence

Malaria rates remain high across many less-developed regions, including Southeast Asia, Sub-Saharan Africa, and parts of Latin America. Although case studies find elevated malaria rates in locales with increased levels of environmental degradation, the current body of comparative environmental research lacks investigation of infectious disease trends. This study draws upon world-system theorizing to consider agricultural export flows and resulting alterations to the natural environment in poor nations as key causes of malaria prevalence. Additionally, relationships among world-system position, economic development, and socio-health characteristics are examined alongside the environmental predictors using structural equation modeling for data on 99 less-developed nations. The findings emphasize that deforestation and biodiversity loss associated with primary sector export flows are key drivers of malaria rates, alongside notable influences of basic health and social services. The results suggest that environmental and social conditions greatly shape malaria transmission in poor societies.     

Modernization and the Demographic Transition: Cross-Sectional and Longitudinal Analyses of a Revised Model

Abstract

We specify a revised model of the demographic transition which accounts for national fertility levels and changes over the past two decades. The model includes cultural, geographic, demographic and family planning program variables, in addition to a measure of national socio-economic modernization. Using crude birth rates for 117 countries, we operationalize and then apply the revised model to 1974 rates, and then test a longitudinal model of 1955–59 to 1974 change in rates. A final model for 81 less developed nations from the original set of 117 countries includes a measure of family planning program effort. Including this highly significant measure in a model of 1955–59 to 1974 change results in further evidence favoring modification of the traditional demographic transition model. Implications for the future course of fertility in underdeveloped countries are discussed.     

Building cultural competence: A systematic evaluation of the effectiveness of culturally sensitive interventions with ethnic minority youth

Growing diversity within the US population accentuates the need for the development and implementation of culturally competent services in the field of child welfare. Despite this, few studies exist that examine the effectiveness of culturally sensitive interventions (CSIs) with ethnic minority populations, who are considerably more at risk of developing psychosocial problems including substance and alcohol abuse, delinquency, low academic achievement, and poor self-esteem. With the demand for evidence-based practice it is imperative that we examine the effectiveness of CSIs designed to prevent and treat youth problems. The main goal of this review was to systematically analyze the methodology of recent CSI research with populations of ethnic minority youth in order to evaluate each intervention's ability to adhere to existing standards of evidence-based practice. The fifteen CSI studies examined in this review illustrate progress in their attempt to adhere to the methodological rigor required of evidence-based practice. This review encourages the field of child welfare to position itself analogously with and embrace the movement toward building cultural competence by further investigating the effectiveness of culturally-sensitive interventions with ethnic minority youth.     

Embedded cultural values and international transaction cost advantages

Culturally embedded differences in self-interested behavior and perceptions of trust violate the universal assumption of moral hazard held by transaction cost economic theorists. A model of transaction cost advantage is derived and propositions developed using the cultural value diversity literature to test the universal assumptions of transaction cost economics.     

Determinants of fertility levels and change among developed countries: 1958–1978

This article provides a multivariate cross-national test of the hypothesis that national population/family planning policies have effected levels, and changes in fertility in developed nations over the past two decades. Variation is assessed in the total fertility rates (TFR) in 1978, and in the change in these rates between 1958 and 1978, among thirty developed countries. Measures include socioeconomic development, divorce, percent in consensual unions, female labor force participation, abortion policy, and level of contraceptive use by married couples and, government population/family planning policy. Seventy percent of the variation in 1978 TFR is related to the percent contracepting, female labor force, and the population/family planning policy measures. These are the only measures with significant direct effects. A longitudinal analysis of 1958 to 1978 change in TFRs is also conducted. This model increases R² to 75%, and the three independent variables remain significant. Implications of these findings for policy makers interested in increasing or decreasing fertility rates are noted.
