Shaping of the migratory process in northern Mexico, 1930-1990

"During the third decade of this century Mexican geographical structure began to change notoriously. Due to the strong influence of [the] North American economy, the north of Mexico became progressively one of the most important regions in the country, with the emergence of favorable perspectives of economic growth. Soon it became attractive to migration from the demographically pressed regions of Central Mexico. Thus, the north of Mexico was favored by the presence of qualified workers and a growing population. However, the region was not evenly populated, due to geographic, historic, and socio-economic factors that...[affect] the processes of migration and settlement. Some regions present important changes in their migratory flow, evidenced by the presence of new entities of origin and the disappearance of others." (SUMMARY IN ENG)     

Reversing Directions: A Ranking and Comparison of Key U.S. Intergovernmental Events, 1960-1980 and 1980-1995

Based on surveys of scholars and practitioners, this articleranks and evaluates the significance of intergovernmental eventsand trends of I980 to I995, and also compares these with similarrankings for 1960 to 1980. The most important events of the1980 to 1995 period were found to be those that generally diminished,or potentially may diminish, the role of the federal governmentin intergovernmental affairs. It was also found that the eventsand trends which scholars rated highly for 1960 to 1980 generallyremained the top events and trends of that period as viewedby current scholars. It is concluded that events and trendsthat seem important and influential at this point in lime probablywill remain comparatively significant, even when evaluated inthe context of the passage of time.     

Financing Arlington County, Virginia's Capital Programs: The Experience of the 1980s, The Outlook for the 1990s

County governments in the 1970s had few responsibilities beyond the courts and jail functions. Now, due to large suburban growth in the 1980s, county governments will find themselves immersed in capital financing issues. Arlington County, Virginia, is the setting of this article on the effects of major financings in the 1980s on a county government in the 1990s.

Developments and trends in Social Security, 1990-1992: overview of principal trends.

The article that follows is a reprint of Part I of a report presented by Dalmer D. Hoskins, Secretary General of the International Social Security Association (ISSA), to the organization's XXIVth General Assembly (November 1992, Acapulco). It identifies and interprets the major trends currently influencing the evolution of social security programs around the world, and analyzes these developments against the backdrop of the current economic, demographic, and social environment in which these programs operate. (Part II of the report analyzes the changes according to each major branch of social security; an annex to the report provides more detailed information and source citations in reference to these changes.) The ISSA is a nongovernmental international organization headquartered in Geneva, Switzerland. It is made up of 321 social security-related institutions, including the U.S. Social Security Administration, in 122 countries. The Association's aim is to protect, promote, and develop social security worldwide.     

The strange death of president Zachary Taylor: A case study in the manufacture of mainstream history

Abstract

Was President Zachary Taylor poisoned? Sometimes an event in history wins our attention not solely because of its generalizable significance but because of its inviting singularity. In addition, the Taylor case is a perfect example of how “pack journalists” and “pack historians” can settle a controversy by fiat, manufacturing orthodox conclusions out of thin air, in this instance telling us to believe in the “cherries and milk” death of a president. The case demonstrates the sloppy and superficial investigative methods of both pathologists and mainstream historians. It also demonstrates how ideological gatekeepers rush to close ranks against any issue that challenges their expertise, or challenges the legitimacy and virtue of US political institutions by suggesting the possibility of conspiracy in high places.     

The net effects of the Project NetWork return-to-work case management experiment on participant earnings, benefit receipt, and other outcomes

The Social Security Administration (SSA) initiated Project NetWork in 1991 to test case management as a means of promoting employment among persons with disabilities. The demonstration, which targeted Social Security Disability Insurance (DI) beneficiaries and Supplemental Security Income (SSI) applicants and recipients, offered intensive outreach, work-incentive waivers, and case management/referral services. Participation in Project NetWork was voluntary. Volunteers were randomly assigned to the "treatment" group or the "control" group. Those assigned to the treatment group met individually with a case or referral manager who arranged for rehabilitation and employment services, helped clients develop an individual employment plan, and provided direct employment counseling services. Volunteers assigned to the control group could not receive services from Project NetWork but remained eligible for any employment assistance already available in their communities. For both treatment and control groups, the demonstration waived specific DI and SSI program rules considered to be work disincentives. The experimental impact study thus measures the incremental effects of case and referral management services. The eight demonstration sites were successful in implementing the experimental design roughly as planned. Project NetWork staff were able to recruit large numbers of participants and to provide rehabilitation and employment services on a substantial scale. Most of the sites easily reached their enrollment targets and were able to attract volunteers with demographic characteristics similar to those of the entire SSI and DI caseload and a broad range of moderate and severe disabilities. However, by many measures, volunteers were generally more "work-ready" than project eligible in the demonstration areas who did not volunteer to receive NetWork services. Project NetWork case management increased average annual earnings by $220 per year over the first 2 years following random assignment. This statistically significant impact, an approximate 11-percent increase in earnings, is based on administrative data on earnings. For about 70 percent of sample members, a third year of followup data was available. For this limited sample, the estimated effect of Project NetWork on annual earnings declined to roughly zero in the third followup year. The findings suggest that the increase in earnings may have been short-lived and may have disappeared by the time Project NetWork services ended. Project NetWork did not reduce reliance on SSI or DI benefits by statistically significant amounts over the 30-42 month followup period. The services provided by Project NetWork thus did not reduce overall SSI and DI caseloads or benefits by substantial amounts, especially given that only about 5 percent of the eligible caseload volunteered to participate in Project NetWork. Project NetWork produced modest net benefits to persons with disabilities and net costs to taxpayers. Persons with disabilities gained mainly because the increases in their earnings easily outweighed the small (if any) reduction in average SSI and DI benefits. For SSA and the federal government as a whole, the costs of Project NetWork were not sufficiently offset by increases in tax receipts resulting from increased earnings or reductions in average SSI and DI benefits. The modest net benefits of Project NetWork to persons with disabilities are encouraging. How such benefits of an experimental intervention should be weighed against costs of taxpayers depends on value judgments of policymakers. Because different case management projects involve different kinds of services, these results cannot be directly generalized to other case management interventions. They are nevertheless instructive for planning new initiatives. Combining case and referral management services with various other interventions, such as longer term financial support for work or altered provider incentives, could produc     

A method for projecting the population according to size of locality. (Application to the case of Mexico's urban population in 1990)

"In this article, a restricted components method is presented (because sex and age are not taken into account) to project the population classified according to the size of the locality.... The application is presented for urban centers (15,000 or more inhabitants) of Mexico in 1990, utilizing the trend in demographic growth for the 1960-1980 period." Data are from Mexican censuses conducted in 1960, 1970, and 1980. (SUMMARY IN ENG)     

The internal consistency of corrected labor force data in the census (1960-1980) and the estimation of labor force participation rates by age and sex for 1980

This work examines the internal consistency of corrected estimates of the economically active population in the Mexican censuses of 1960 through 1980, estimates participation rates by age and sex for 1980, and determines the degree of overestimation or underestimation of the 1980 census. The first section reviews results of evaluations of information on the active population and examines the internal consistency of the different estimates. The second establishes criteria for correction of participation rates by age and sex for 1980 and estimates the degree of overestimation or underestimation, and the third assesses the advantages and limitations of the results. Comparison of results from several studies suggests that the labor force was significantly overestimated in the 1960 and 1980 censuses and underestimated in the censuses of 1970 and 1990. Estimates of overestimation in the 1960 census ranged from 8.5 to 14.3%, while estimates of underestimation in 1970 ranged from -0.5% to -0.8%. Estimates of overestimation in 1980 ranged from 6.6% to 21.6%. Internal consistency of labor force data was also assessed through a comparative analysis of average rates of growth of the population aged 12 and over and of the economically active population according to the census and the various corrections. The study concluded that the female labor force was overestimated by 1.6 million workers in 1980, or 27.1%, while the male labor force was overestimated by 610,000 workers, or 4%. The total labor force was overestimated by around 10%. These estimates for 1980 appear more congruent with general trends in male and female labor force participation, and also with the rate of growth of the population over age 12.     

The changing geography of metropolitan opportunity: The segregation of the poor in U.S. metropolitan areas, 1970 to 1990

Abstract

This analysis uses census tract data to measure the segregation of the poor in U.S. metropolitan areas in 1970, 1980, and 1990. Two measures of segregation are used: the indices of dissimilarity and isolation.

In 1990 the mean dissimilarity of the poor in the 100 largest U.S. metropolitan areas was 36.1, which is substantial but below the 60.6 dissimilarity of blacks. The 1990 isolation of the poor was 21.0. From 1970 to 1990, the dissimilarity of the poor increased by 11 percent, and the isolation of the poor rose by 9 percent; in contrast, racial segregation declined. Exploratory regression analyses reveal that income segregation in metropolitan areas was significantly greater in 1990 and increased more from 1970 to 1990 in the Northeast than in the South and West. Midwest areas generally were not significantly different from Northeast areas in 1990 segregation levels or in changes from 1970 to 1990.
