The exceptionally high life expectancy of Costa Rican nonagenarians

Robust data from a voter registry show that Costa Rican nonagenarians have an exceptionally high live expectancy. Mortality at age 90 in Costa Rica is at least 14% lower than an average of 13 high-income countries. This advantage increases with age by 1% per year. Males have an additional 12% advantage. Age-90 life expectancy for males is 4.4 years, one-half year more than any other country in the world. These estimates do not use problematic data on reported ages, but ages are computed from birth dates in the Costa Rican birth-registration ledgers. Census data con rm the exceptionally high survival of elderly Costa Ricans, especially males. Comparisons with the United States and Sweden show that the Costa Rican advantage comes mostly from reduced incidence of cardiovascular diseases, coupled with a low prevalence of obesity, as the only available explanatory risk factor. Costa Rican nonagenarians are survivors of cohorts that underwent extremely harsh health conditions when young, and their advantage might be just a heterogeneity in frailty effect that might disappear in more recent cohorts. The availability of reliable estimates for the oldest-old in low- income populations is extremely rare. These results may enlighten the debate over how harsh early-life health conditions affect older-age mortality.     

A modification for use in destabilized populations of brass's technique for estimating completeness of death registration

Summary Brass has developed a method of estimating completeness of death registration using only data on deaths and population by age and sex. In this paper, his method is briefly outlined and the assumptions upon which it is based are discussed. In particular, the implications of the failure of the assumption of stability of the population are investigated. It is found that in populations where mortality has been declining, use of the technique leads to underestimation of completeness. A modification of the technique based on knowledge of the duration and rate of mortality change is proposed for use in such populations. Using simulated destabilized populations, the modification is tested and found to yield more accurate estimates of completeness of death registration than the unmodified technique. The usefulness of the modified technique is further illustrated by applying it to data for Costa Rican females in 1963.     

Childhood disadvantages and the timing of the onset of natural menopause in Latin America and the Caribbean

The aim of this study is to investigate the association of early life factors with the timing of the onset of natural menopause in Costa Rica and Puerto Rico. We use Cox proportional hazard models to estimate the risk of the onset of menopause. Our results suggest that socioeconomic disadvantages, as expressed by difficulties attending school due to economic hardships or parents never living together, increase the risk of the onset of natural menopause among Puerto Rican women. Among Costa Rican women, early life nutrition, estimated using anthropometric measures, is related to the timing of the onset of natural menopause.     

Union Formation Implications of Race and Gender Gaps in Educational Attainment: The Case of Latin America

We use census microdata to assess the levels of educational homogamy in six Latin American countries: Argentina, Brazil, Chile, Costa Rica, Ecuador and Mexico. This paper contributes to the literature on homogamy in three ways. First, by conducting a comparative analysis between countries belonging to the still little-studied region of Latin America, which is still undergoing intense and varied processes of demographic, economic, social, and political modernization. Second, by simultaneously including variables of structural and individual nature. Finally, by making progress with respect to the interactions between educational homogamy and other important variables associated with high levels of social inequality in the region: race, ethnicity and birthplace.     

Dual Citizenship Rights: Do they Make More and Richer Citizens?

In the 1990s, Colombia, the Dominican Republic, Ecuador, Costa Rica, and Brazil passed dual citizenship laws granting their expatriates the right to naturalize in the receiving country without losing their nationality of origin. I estimate the effects of these new laws on naturalization rates and labor market outcomes in the United States. Based on data from the 1990 and 2000 U.S. censuses, In find that immigrants recently granted dual nationality rights are more likely to naturalize relative to immigrants from other Latin American countries. They also experience relative employment and earnings gains, together with drops in welfare use, suggesting that dual citizenship rights not only increase the propensity to naturalize but may also promote economic assimilation. The effects of dual citizenship on improved economic performance, if mediated through naturalization, are consistent with American citizenship conferring greater economic opportunities.     

Measuring Overeducation: Incidence,Correlation and Overlaps Across Indicators and Countries

The methodological debate on how to measure overeducation has been present since the introduction of the topic in the academic debate. Nevertheless, there is still no consensus on a preferred indicator. This article aims at contributing to the existing methodological debate providing systematic and cross-country evidence on the variation across overeducation measurements. Using REFLEX/HEGESCO and EULFS datasets, I provide evidence on within and across countries variation on the incidence, correlation and overlaps across the main types of objective, statistical and subjective overeducation indicators. Results suggest that worker’s self-reported indicators better cope with comparative studies, while in single-country studies objective indicators are likely to provide a more in-depth and detailed measurement. The use of statistical indicators is advised in contexts with labour markets that easily adapt to educational and employment changes, especially if these are not affected by credential inflation. However, it is advisable to use more than one indicator whenever data allows it, as different types of overeducation measurements provide different outcomes and results are likely to be complementary rather than excluding information on the overeducation phenomenon. This is especially relevant when overeducation is used as a dependent variable rather than a predictor. An initial review and discussion of the existing types of overeducation measurements and their advantages and drawbacks precedes the empirical evidence.

     

The Effect of Child Mortality on Contraceptive Use and Fertility in Colombia,Costa Rica and Korea

In this paper the question whether reproductive behaviour is consciously altered by the death of a child is answered by using World Fertility Survey data from Colombia, Costa Rica, and Korea. Alternative strategies are proposed by which women replace children who have died. They may choose to contracept for a shorter period following the death of a child, or they may cease using contraception. Each strategy is analysed separately for selected birth intervals and its effect estimated with loglinear techniques. It is found that the timing and nature of the response to child mortality appear to depend on the stage reached in a country's fertility transition.     

The age at first birth and timing of the second in Costa Rica and Guatemala

This paper explores the relationship between the age at first birth and the timing of subsequent fertility in Costa Rica and in four rural villages and two urban areas of Guatemala. The results indicate that, for Costa Rica, the age at first birth is significantly related to the tempo of subsequent births, and that this association, at least for the interval to second birth, remains significant when socio-economic factors and marital status at the time of first birth are held constant. While the results suggest that the age at first birth is related to timing of the second in the Guatemalan sample as well, the association is weaker and less consistent than in Costa Rica.     

Sex preference and fertility: what is the link?

It is argued that investment in programs for changing attitudes toward sex preference may not have the greatest impact on reducing fertility or increasing fertility control. Arnold's new method of analysis of determining sex preference was applied to data from a 1977 Egyptian survey of 36,000 rural households in Menoufia Governorate. Findings indicated that couples increased their use of modern contraceptives in direct proportion to an increase in the number of sons. Arnold determined that a large majority of all couples would have at least one boy early in their childbearing years. Thus sex preference would not have a large effect on fertility. Arnold's analysis among 27 countries found that without any sex preference, contraceptive usage would increase by an average of less than 3.7 percentage points. Arnold found that sex preference was strongest in Asia, particularly in South Korea and Taiwan that already have reduced fertility levels. In Africa, where fertility is high, the total elimination of sex preference would have only a 2.9 percentage point difference in contraceptive use. Sex preference had small effects on the percent of women who practice contraception, the percent who desire no more children, and the average number of additional children wanted. For example, in Bangladesh having no sex preference would show a percentage difference of 1.6 percentage points for contraceptive use, 4.7 percentage points difference for women desiring no more children, and -0.1 percentage point difference for the average number of additional children wanted. The effect of having no sex preference was strongest in India compared with Bangladesh, Indonesia, Nepal, the Philippines, Thailand, Ghana, Kenya, Costa Rica, Haiti, Paraguay, and Peru. The effect of no sex preference in India would have the respective percentage point effect of 3.7, 8.9, and -0.2. Public policy should be directed to information, education, and communication with other social goals.     

Gender and Racial Stereotyping in Rape Coverage

This article uses critical discourse analysis to discuss and analyse articles about rape that appeared in a South African newspaper, Grocott's Mail, between 14 October, 2008 and 29 October, 2009. Drawing on existing literature on “rape myths” in media coverage of rape, this article argues that Grocott's Mail perpetuates racial and gender stereotypes through the way in which it reports on rape. While not all of the articles included in the analysis use rape myths, most use one or more when discussing rape incidents. Specifically, Grocott's Mail tends to use rape myths that blame the victim for the rape and de-emphasise the role of the perpetrator in the rape.     

Spatial Variation In Migration Processes And Development: A Costa Rican Example Of Conventional Modeling Augmented By The Expansion Method

The ways in which migration and development have been linked in previous research in Third World settings are reviewed. Intercantonal migration in Costa Rica is analyzed, first in terms of a conventional model and then in terms of a paradigm of migration that focuses on place-to-place variations in development milieu. The results show there is spatial variation in the role of most variables and that these variations follow a reasonably consistent pattern with regard to development conditions. A series of maps graphically illustrates the importance of a spatial frame of reference.     

Child support and the postdivorce economic well-being of mothers, fathers, and children

This article provides national estimates of the current and potential impact of private child support transfers on the economic well-being of custodial and noncustodial families following marital dissolution. Mothers and children fare dramatically worse than fathers after marital dissolution; these differences, however, would be much more pronounced in the absence of private child support. Simulations of four existing child support guidelines show that substantial increases in economic well-being among mother-custody families are possible within the structure of the existing child support system, with minimal impact on poverty among nonresident fathers. Under all of these guidelines, however, custodial-mother families would continue to fare substantially worse than nonresident fathers.     

Mobile Music,Coded Objects and Everyday Spaces

Abstract

Building upon the existing work of Michael Bull and others on the everyday practices of mobile music, this article draws upon contemporary work on active and information dense urban spaces to begin to shape opportunities for a research agenda for mobile music that incorporates the technological and informational infrastructures within which it occurs. In particular the piece applies Dodge and Kitchin’s concept of logjects, devices that recall and communicate their history of use, to the case of the mobile music device. The article concludes with a discussion of the significance of these infrastructures for the study of mobile music and with some brief reflections linking this conceptualisation and example to contemporary debates on the future development of the social sciences.     

Population and Deforestation in Costa Rica

This paper addresses a central debate in research and policy on population and environment, namely the extent to which rapid population growth is associated with the massive deforestation currently underway in the tropics. We utilize the experience of Costa Rica during the last forty years to illustrate what the main issues are, discuss the history of deforestation in that country, and present results from conventional regression methods and from the application of spatial analyses. These analyses enable us to estimate the magnitude of the relation between population and deforestation and to identify the factors that are responsible for the linkage between them.     

Ethnic Minorities in Northern Mountains of Vietnam: Employment,Poverty and Income

The Italian National Statistical Office is implementing a new project for computing sub-national Purchasing Power Parities (PPPs) on a regular basis, which is based on an appropriate use of existing Consumer Price Index (CPI) data and new sources of data. Concerning the use of CPI data, in this paper the role of the Country Product Dummy (CPD) method for compiling sub-national PPPs at Basic–Heading (BH) level is analysed together with the specific issues that arise in this context, such as the need to take spatial autocorrelation among price relatives into account. The results of various experiments based on CPI data concerning 7 BHs and 19 Italian regional chief towns are presented and discussed with the aim of exploring the performance of various CPD models and analysing to what extent the type and characteristics of the data affect the estimates obtained. The statistical uncertainty associated with the ranks derived from the regional PPPs was then calculated by means of a simulation procedure. Our findings prove to be interesting and confirm that methods and CPI data for spatial comparisons are reciprocally influenced.     

Globalizing the Nation-State: The Shipping Container and American Infrastructure

Abstract

This article focuses on the impact of the shipping container on the trucking and railroad infrastructures of the USA, and describes how global containerization and American transportation have mutually influenced each other. As the container moves not only over the ocean but also within national territories, its use represents a globalizing of the infrastructure, territory, and internal workings of the nation-state. The national scale, once dominant, gives way to a multiplicity of scalar relations. Yet because the container functions by using existing transportation infrastructures, it forms a network dependent on the systems and practices of the nation-state. Globalization in this case is not a top-down phenomenon whereby the global exerts its will upon other scales that can only react, but a more complex process in which a variety of scales and actors possess agency and power.     

Non-Heterosexuality,Relationships, and Young Women’s Contraceptive Behavior

Non-heterosexual young women have a higher rate of unintended pregnancy than their heterosexual peers, but their fertility behaviors are understudied. We use longitudinal data from the Relationship Dynamics and Social Life study to investigate mechanisms contributing to non-heterosexual women’s higher pregnancy risk. These data include weekly reports of relationships, sex, and contraceptive use over 30 months. We compare the relationships and fertility behaviors of three groups: exclusively heterosexual (consistent heterosexual behavior, identity, and attraction); mostly heterosexual (heterosexual identity with same-sex behavior and/or same-sex attraction); and LGBTQ (any non-heterosexual identity). We find that mostly heterosexual and LGBTQ women behave differently from exclusively heterosexual women in ways likely to elevate their risk of unintended pregnancy: more distinct partners during the study period, more sexual intercourse with men, less frequent contraceptive use, less use of a dual method (condom plus hormonal method), and more gaps in contraceptive coverage. Mostly heterosexual women resemble LGBTQ women in their contraceptive behavior but have significantly more intercourse with men, which may increase their pregnancy risk relative to both LGBTQ and exclusively heterosexual women. We conclude by considering implications for LGBTQ health and the measurement of sexual minority populations.     

Occupational mobility and fertility in metropolitan Latin America

The relation between career mobility and reproductive behavior is examined for five cities of developing Latin American nations: Bogota, Columbia; San Jose, Costa Rica; Mexico City, Mexico; Panama City, Panama; and Caracas, Venezuela. The data are obtained from fertility surveys conducted between September, 1963, and August, 1964, in the above-named cities under the auspices of the Centro Latinoamericano de Demografía (CELADE), and the analysis is based on information from 600–800 women per city who have been married only once and married ten years or more. Career mobility is defined as an occupational change of the husband between the date of marriage and 1963–1964, based on the Hall-Jones occupational scale. Reproductive behavior is operationalized as the number of live births. The conclusion of the multiple classification analysis is that the process of career mobility in four out of five Latin American samples is not a significant factor in explaining differential reproductive behavior. These results are compatible with a variety of North American studies which stress that variation heretofore ascribed to the process of mobility is an additive composite of past and present status effects. These findings are discussed; a theoretical and methodological critique of mobility-fertility research is presented.     

Relationship of Religiosity and Spirituality to Hazardous Drinking,Drug Use,and Depression Among Sexual Minority Women

Using data from Wave 3 of the Chicago Health and Life Experiences of Women (CHLEW) study (N = 699), we explored whether religiosity and spirituality were associated with risk of hazardous drinking, drug use, and depression among sexual minority women (SMW; i.e., lesbian, bisexual) and possible differences by race/ethnicity. Participants were more likely to endorse spirituality than religiosity, and endorsement of each was highest among African American SMW. We found no protective effect of religiosity or spirituality for hazardous drinking or drug use. An association initially found between identifying as very spiritual and past-year depression disappeared when controlling for help-seeking. Among SMW with high religiosity, African American SMW were more likely than White SMW to report hazardous drinking. Latina SMW with higher spirituality were more likely than White SMW to report drug use. Results suggest that religiosity and spirituality affect subgroups differently, which should be considered in future research on resiliency among SMW.
