Terms modified by Mexican Selected AbstractsThe association between incisor trauma and occlusal characteristics in individuals 8,50 years of ageDENTAL TRAUMATOLOGY, Issue 2 2004Jay D. Shulman Abstract,,, To explore the association between incisal trauma and occlusal characteristics using oral examination and health interview data from the Third National Health and Nutrition Examination Survey 1988,1994 (NHANES III). Incisal trauma examinations were performed on 15 364 individuals 6,50 years of age using an ordinal scale developed by the National Institute of Dental and Craniofacial Research. Occlusal examinations were performed on 13 057 individuals 8,50 years of age. We fitted separate multivariate logistic regression models for maxillary and mandibular incisor trauma adjusting for socio-demographic variables (age, gender, race-ethnicity) and occlusal characteristics (overbite, overjet, open bite). 23.45% of all individuals evidenced trauma on at least one incisor, with trauma more than four times more prevalent on maxillary (22.59%) than on mandibular incisors (4.78%). Males (OR = 1.67) had greater odds of trauma than females; Whites (OR = 1.37) and non-Hispanic Blacks (OR = 1.37) had greater odds of trauma than Mexican,Americans. The odds of trauma increased with age, peaked from age 21 to 30 (OR = 2.92), and declined. As overjet increased, so did the odds of trauma. Compared to individuals with ,0-mm overjet, odds of trauma increased from 1,3 mm (OR = 1.42) to 4,6 mm (OR = 2.42) to 7,8 mm (OR = 3.24) to >8 mm (OR = 12.47). Trauma to incisors is prevalent but mostly limited to enamel. Trauma to maxillary incisors is associated with overjet, gender, race-ethnicity, and age, while trauma to mandibular incisors is associated with gender, age, and overbite. [source] Geography and the Immigrant Division of LaborECONOMIC GEOGRAPHY, Issue 3 2007Mark Ellis Abstract: Immigrants concentrate in particular lines of work. Most investigations of such employment niching have accented either the demand for labor in a limited set of mostly low-wage industries or the efficiency of immigrant networks in supplying that labor; space has taken a backseat or has been ignored. In contrast, this article's account of immigrant employment niching modulates insights built on social network theories with understandings derived from relative location. We do so by altering the thinking about employment niches as being metropolitan wide to considering them as local phenomena. Specifically, the analysis examines the intraurban variation in niching by Mexican, Salvadoran, Chinese, and Vietnamese men and women in four industries in Los Angeles. Niching is uneven; in some parts of the metropolitan area, these groups niche at high rates in these industries, whereas in others, there is no unusual concentration. We show how a group's propensity to niche in an industry is generally higher when the industry is located close to the group's residential neighborhoods and demonstrate the ways in which the proximity of competing groups dampens this geographic advantage. The study speaks to debates on immigrant niching and connects with research on minority access to employment and accounts of the agglomeration of firms. More generally, it links the geographies of home and work in a new way, relating patterns of immigrant residential segregation to those of immigrant employment niches. [source] Variation in Food Purchases: A Study of Inter-Ethnic and Intra-Ethnic Group Patterns Involving the Hispanic CommunityFAMILY & CONSUMER SCIENCES RESEARCH JOURNAL, Issue 4 2001Geoffrey D. Paulin The Hispanic community in the United States is growing rapidly. Understanding food expenditure patterns for this group is of increasing importance. Yet, as implied by the term Hispanic community, most literature treats Hispanics as one group rather than as a collection of diverse cultures with some common linguistic and other characteristics. This article uses data from the 1995 and 1996 U.S. Consumer Expenditure Diary Surveys to examine food expenditure patterns for Hispanics as a group compared to non-Hispanics and for subgroups within the Hispanic community (i.e., families of Mexican, Puerto Rican, Cuban, Central and South American, or other Spanish origin). The data show not only that Hispanics in general have different food expenditure patterns than non-Hispanics, but also, and perhaps more important, that the subgroups within the Hispanic community are not homogeneous in their food expenditure patterns. Researchers should recognize the diversity in the Hispanic population when considering goals for nutritional and related policies. [source] Conducting Focus Groups with Latino Populations: Lessons from the Field,FAMILY RELATIONS, Issue 3 2004Adriana J. Umaña-Taylor We explore the use of focus groups with Latino families. Based on our work with Colombian, Guatemalan, Mexican, and Puerto Rican mothers, we review the factors that make this methodology particularly useful for working with these families. In addition, we provide a number of strategies for making the use of focus groups with Latino populations successful. These strategies can be broadly applied to practical aspects of working with Latino populations, as well as in research settings. [source] Cloning and characterization of novel snake venom proteins that block smooth muscle contractionFEBS JOURNAL, Issue 11 2002Yasuo Yamazaki In this study, we isolated a 25-kDa novel snake venom protein, designated ablomin, from the venom of the Japanese Mamushi snake (Agkistrodon blomhoffi). The amino-acid sequence of this protein was determined by peptide sequencing and cDNA cloning. The deduced sequence showed high similarity to helothermine from the Mexican beaded lizard (Heloderma horridum horridum), which blocks voltage-gated calcium and potassium channels, and ryanodine receptors. Ablomin blocked contraction of rat tail arterial smooth muscle elicited by high K+ -induced depolarization in the 0.1,1 µm range, but did not block caffeine-stimulated contraction. Furthermore, we isolated three other proteins from snake venoms that are homologous to ablomin and cloned the corresponding cDNAs. Two of these homologous proteins, triflin and latisemin, also inhibited high K+ -induced contraction of the artery. These results indicate that several snake venoms contain novel proteins with neurotoxin-like activity. [source] Market based debt reduction agreements: a case study on Mexican and Polish Brady bondsINTERNATIONAL JOURNAL OF FINANCE & ECONOMICS, Issue 2 2001Luca Barbone F34; G14 Abstract This paper analyzes some aspects of the workings of the Brady bond (restructured Less Developed Countries debt) market. It concentrates on the effects of the December 1994 Mexican crisis on the risk assessment (as measured by the stripped spread) of Poland, another Brady country. The main findings are: (i) over the sample period, the unit root hypothesis on the risk premium (measured by the stripped spread) of Mexico and Poland cannot be rejected; this is consistent with the idea that the risk premium reflects new information accruing to the market; (ii) comovements in stripped spreads between Mexico and Poland were stronger during the period of the Peso crisis: we do not reject the null of cointegration for the year that includes the crisis (July 1994,July 1995), but we do reject the null for the year starting 6 months after the crisis (July 1995,July 1996); (iii) the crisis has had a strong permanent effect on the risk assessment of Mexico with respect to the one of Poland (550 basis points circa).

[source] Can Migration Foster Development in Mexico?INTERNATIONAL MIGRATION, Issue 5 2009Inequality, The Case of Poverty The impact of migration on development can be analysed from a number of perspectives. This article focuses on poverty and inequality. It assesses the relative contribution of migrants to Mexico,s economy through remittances, compared to other Latin American countries; analyses the distributional impact of remittances (with an emphasis on the poor), and compares this impact to the counterfactual impact of migrants' stay-at-home income. It explains the processes leading to scant economic success rates among poor international migrants. Finally, it describes the nature and impact of current Mexican migrant-oriented policies, and recommends a shift in focus, to lessen emigration, increase the income of migrants, promote returns, and bolster the economic impact of returning migrants. [source] Geographic Mobility and Spatial Assimilation among U. S. Latino Immigrants,INTERNATIONAL MIGRATION REVIEW, Issue 3 2005Scott J. South Although the spatial assimilation of immigrants to the United States has important implications for social theory and social policy, few studies have explored the atterns and determinants of interneighborhood geographic mobility that lead to immigrants'residential proximity to the white, non-Hispanic majority. We explore this issue by merging data from three different sources - the Latino National Political Survey, the Panel Study of Income Dynamics, and tract-level census data - to begin unraveling causal relationships among indicators of socioeconomic, social, cultural, segmented, and spatial assimilation. Our longitudinal analysis of 700 Mexican, Puerto Rican, and Cuban immigrants followed from 1990 to 1995 finds broad support for hypotheses derived from the classical account of minority assimilation. High income, English language use, and embeddedness in Anglo social contexts increase Latino immigrants'geographic mobility into Anglo neighborhoods. U. S. citizenship and years spent in the United Stares are ppsidvely associated with geographic mobility into more Anglo neighbor oods, and coethnic contact is inversely associated with this form of mobility, but these associations operate largely through other redictors. Prior experiences of ethnic discrimination increase and residence in public housing decreases the likelihood that Latino immigrants will move from their origin neighborhoods, while residing in metropolitan areas with large Latino populations leads to geographic moves into "less Anglo" census tracts. [source] The Determinants of Being Unbanked for U.S. ImmigrantsJOURNAL OF CONSUMER AFFAIRS, Issue 1 2006SHERRIE L. W. RHINE Random-effects binary choice models are estimated to identify the attributes that influence the likelihood that immigrants are unbanked. This study finds that the likelihood to be unbanked is higher for immigrants with less education, poverty-level income, or a larger family but lower for immigrants with greater net worth or higher income. Among immigrant groups, Mexican and other Latin American immigrants have the highest rates of being unbanked. Programs aimed at helping immigrants move into the financial mainstream may benefit from taking into account the differences in socioeconomic attributes and migration experiences of specific populations. [source] RELATIONSHIP STATISFACTION OF MEXICAN AMERICAN AND NON-HISPANIC WHITE AMERICAN INTERETHNIC COUPLES: ISSUES OF ACCULTURATION AND CLINICAL INTERVENTIONJOURNAL OF MARITAL AND FAMILY THERAPY, Issue 3 2000Charles Negy Despite the increasing prevalence of interethnic marriages, remarkably little empirical literature exists for guiding clinical interventions offered to these couples. This study compared the marriages of 72 couples with one Mexican-American partner and one non-Hispanic White American partner, 75 Mexican-American couples, and 66 non-Hispanic White couples. Overall, the interethnic couples were more similar to non-Hispanic White couples than they were to Mexican-American couples across multiple domains, with the latter group indicating modestly higher levels of relationship distress. Among interethnic couples, Mexican-American wives' level of acculturation related significantly to both their own marital- and parental-role orientation and to distress in their relationships with children, as well as to their husbands' marital distress regarding child rearing and the couple's interactions regarding finances. Implications for clinical interventions with Mexican- and White-American interethnic couples are discussed. [source] Equations to predict precipitation onset and bubblepoint pressures of asphaltenic reservoir fluidsAICHE JOURNAL, Issue 7 2009J. M. del Rio Abstract A set of algebraic equations to predict upper onset-of-precipitation and bubble-point pressures of asphaltene-containing reservoir fluids in wide temperature ranges are proposed. In developing the equations, laboratory data of 11 Mexican and 12 more live oils have been analyzed, and a correlation of these data with temperature has been found. A modified least-squares regression method has been used to develop two versions of the proposed equations. In one version, a single pressure/temperature data point is required to predict the entire onset/bubble-point curves at any temperature. For oils with no experimental precipitation data available at all, a second version of the proposed expressions employs standard chromatographic data of the reservoir fluid to provide a reasonable prediction. The average absolute deviations in calculated onset and bubble-point pressures by the proposed equations are 2.53 and 0.45MPa by the one-point correlations, respectively, and 3.96 and 1.62 MPa by the compositionally-based correlations, respectively. The developed expressions are simple and can be used to provide reasonable predictions of upper onset and bubble-point pressures of asphaltenic live oils in cases where laboratory data are scarce. © 2009 American Institute of Chemical Engineers AIChE J, 2009 [source] ,I'm Mexican, remember?' Constructing ethnic identities via authenticating discourse1JOURNAL OF SOCIOLINGUISTICS, Issue 2 2007Petra Scott Shenk This paper examines how an ideology of cultural authenticity emerges in the casual but playful conversations of a bilingual Mexican American friendship group. Authenticating discourse, as illustrated here, is part of an ongoing, ordinary interactional routine through which speakers take overt (authentication) stances, which I call authenticating moves, to display, impugn, vie for, and enact forms of ethnic identity. In the data, issues of authenticity in relation to Mexicanness emerge as a result of the interactional exploitation of three ideological constructs: purity of bloodline, purity of nationality, and Spanish linguistic fluency. [source] HLA-DRB1*08 allele may help to distinguish between type 1 diabetes mellitus and type 2 diabetes mellitus in Mexican childrenPEDIATRIC DIABETES, Issue 1 2007Ana L Rodríguez-Ventura Background:, It may be difficult to distinguish type 1 diabetes mellitus (T1DM) from type 2 diabetes mellitus (T2DM) in the pediatric population. Autoantibodies may help to differentiate both types of diabetes, but sometimes these are positive in patients with T2DM and negative in patients with T1DM. The human leukocyte antigen (HLA)-DR genotype has been associated with T1DM and with T2DM only in adults and in determined cases. Aim:, To determine the differences in HLA class II allele frequencies in Mexican children with T1DM and T2DM. Methods:, We included 72 children with T1DM, 28 children with T2DM, and 99 healthy controls. All were Mexican, and diabetes was diagnosed according to the clinical and laboratory criteria established by the Expert Committee on the Diagnosis and Classification of Diabetes Mellitus. The HLA-DRB1 typing was performed using polymerase chain reaction,sequence-specific oligonucleotide probe and polymerase chain reaction sequence-specific primers. Results:, We found an increased frequency of HLA-DRB1*08 and a decreased frequency of HLA-DRB1*04 in the group with T2DM vs. T1DM [p = 0.0001, odds ratio (OR) = 10.58, 95% confidence interval (CI) = 3,40.8 and p = 0.0006, OR = 0.24, 95% CI = 0.11,0.53, respectively]. No significant differences were found between HLA-DRB1 alleles in T2DM vs. controls. In the group with T1DM, there was a significantly increased frequency of the HLA-DR4 and HLA-DR3 alleles relative to controls (p = 0.0000001, OR = 3.59, 95% CI = 2.2,5.8 and p = 0.00009, OR = 4.66, 95% CI = 2.1,10.3, respectively). Conclusion:, There are significant differences in the HLA profile in Mexican children with T1DM and T2DM. HLA typing could play a role in the differentiation between both types of diabetes in this population. [source] Prescription and non-prescription analgesic use among the US adult population: results from the third National Health and Nutrition Examination Survey (NHANES III),PHARMACOEPIDEMIOLOGY AND DRUG SAFETY, Issue 4 2003Ryne Paulose-Ram PhD Abstract Purpose To estimate prescription and non-prescription analgesic use in a nationally representative sample of US adults. Methods Data collected during the third National Health and Nutrition Examination Survey (1988,1994), for persons 17 years and older were analyzed (n,=,20,050). During the household interview, respondents reported use, in the last month, of prescription and non-prescription analgesics. Results An estimated 147 million adults reported monthly analgesic use, Prescription analgesic use was 9% while non-prescription use was 76%. Females were more likely than males to use prescription (11 vs. 7%, p,<,0.001) and non-prescription (81 vs. 71%, p,<,0.001) analgesics. Across race,ethnicity groups, males (,8%) and females (11,13%) had similar age-adjusted prescription analgesic use. Non-prescription analgesic use was higher among non-Hispanic whites than non-Hispanic blacks and Mexican,Americans for males (76 vs. 53% (p,<,0.001) and 59% (p,<,0.001), respectively) and females (85 vs. 68% (p,<,0.001) and 71% (p,<,0.001), respectively). With increasing age, prescription analgesic use increased whereas non-prescription use decreased. Approximately 30% of adults used multiple analgesics during a 1-month period. This was more common among females (35%) than males (25%, p,<,0.001) and among younger (17,44 years, 33%) rather than older age groups (45+ years, 26%, p,<,0.001). Conclusions Analgesic use among US adults is extremely high, specifically of non-prescription analgesics. Given this, health care providers and consumers should be aware of potential adverse effects and monitor use closely. Published in 2002 by John Wiley & Sons, Ltd. [source] Acculturation, social support and academic achievement of Mexican and Mexican American high school students: An exploratory studyPSYCHOLOGY IN THE SCHOOLS, Issue 3 2002Eric J. López Concerns about the high dropout rate among Mexican American high school students has led researchers and educators to determine which variables affect academic success. The study investigated two factors associated with academic achievement: acculturation and social support. The sample consisted of 60 ninth-grade students of Mexican decent in a southwestern school district. Results indicated that students identified as highly integrated and strongly Anglo-oriented bicultural tended to have higher academic achievement. In addition, the sample as a whole perceived social support from all four sources. Although no generational effects were identified, females tended to have higher GPAs, and perceive more social support, while the males, interestingly, were slightly more acculturated. © 2002 Wiley Periodicals, Inc. [source] Tracing the geographical origin of beefs being circulated in Korean markets based on stable isotopesRAPID COMMUNICATIONS IN MASS SPECTROMETRY, Issue 1 2010Yeon-Sik Bong We have examined the carbon, nitrogen and oxygen isotopic compositions of American, Mexican, Australian, New Zealand and Korean beefs, which are currently being circulated in Korean markets, to check whether stable isotope ratios can identify their country of origin. Each beef exhibited statistically distinct isotopic compositions, especially in oxygen and carbon, because of the different isotopic compositions of their water and cattle feeds. Nevertheless, their isotopic compositions still showed some overlap, especially among USA, Australian, and Korean beefs, which sometimes resulted in significant misidentification when a single isotope was considered. However, the discrimination was generally successful when both the carbon and the oxygen isotopes were used. Copyright © 2009 John Wiley & Sons, Ltd. [source] Genetic admixture, self-reported ethnicity, self-estimated admixture, and skin pigmentation among Hispanics and Native AmericansAMERICAN JOURNAL OF PHYSICAL ANTHROPOLOGY, Issue 4 2009Yann C. Klimentidis Abstract The relationship between ethnicity and biology is of interest to anthropologists, biomedical scientists, and historians in understanding how human groups are constructed. Ethnic self-identification in recently admixed groups such as Hispanics, African Americans, and Native Americans (NA) is likely to be complex due to the heterogeneity in individual admixture proportions and social environments within these groups. This study examines the relationships between self-identified ethnicity, self-estimated admixture proportions, skin pigmentation, and genetic marker estimated admixture proportions. These measures were assessed using questionnaires, skin color measurements, and genotyping of a panel of 76 ancestry informative markers, among 170 Hispanics and NAs from New Mexico, a state known for its complex history of interactions between people of NA and European (EU) ancestry. Results reveal that NAs underestimate their degree of EU admixture, and that Hispanics underestimate their degree of NA admixture. Within Hispanics, genetic-marker estimated admixture is better predicted by forehead skin pigmentation than by self-estimated admixture. We also find that Hispanic individuals self-identified as "half-White, half Hispanic" and "Spanish" have lower levels of NA admixture than those self-identified as "Mexican" and "Mexican American." Such results highlight the interplay between culture and biology in how individuals identify and view themselves, and have implications for how ethnicity and disease risk are assessed in a medical setting.

[source] Demography, life history and migrations in a Mexican mantled howler group in a rainforest fragmentAMERICAN JOURNAL OF PRIMATOLOGY, Issue 2 2008Víctor Arroyo-Rodríguez Abstract This paper represents the results of a long-term study (1996,2003) on the demographic changes over time of a Mexican mantled howler (Alouatta palliata mexicana) group in a rainforest fragment (40,ha) in Los Tuxtlas, Mexico, with a follow-up census 3 years later (2006). In addition to demographic and life history parameters, we describe six dispersal events. Our results suggest that this group has been expanding during the study period, growing from six to 12 individuals, with an annual average intrinsic growth rate of 0.07, an infant survivorship of 67%, and an average immature to female ratio of 0.90. This increase in size is probably related to the high food availability in their home range. However, fragment isolation may be negatively affecting the dispersal patterns typical of the species, which could result in a loss of genetic variability over time. Am. J.

Ek Drawing from a multiyear ethnography and a longitudinal case study, this article examines how one Guatemalan American teenager negotiates the multiple socializations to ethnic and gender identities in her home, her Pentecostal church, and her high school. She must face processes of Americanization and Mexicanization. Americanization's thrust is to replace the languages and cultures of Latino/a students with English and mainstream middle-class European American ways while Mexicanization pushes Central Americans to Mexican and Chicano dialects of Spanish and ways of being. With respect to gender, Amalia confronts a process of sexualization, particularly in school. Tensions between the socializations create spaces where Amalia enacts her agency and constructs her identities. The article is informed by research on multiple socializations, scholarship on identity and agency, and studies of Latino/a language and identities.,[Latina, socialization, language, identity, agency] [source] Genetic relationship between Litopenaeus setiferus (L.) and L. schmitti (Burkenroad) determined by using 16S mitochondrial sequences and enzymatic analysisAQUACULTURE RESEARCH, Issue 12 2003L Arena Abstract Genetic differentiation and variability data of two populations of two species of shrimp (Litopenaeus setiferus (L.) and L. schmitti (Burkenroad)) have been obtained by electrophoretic analysis and by analysis of 16S mitochondrial DNA. Using eight polymorphic enzymes, the genetic distance (GD) between the two species was 0.165. The GD between L. setiferus populations was 0.0057 and between L. schmitti populations it was 0.0034. The greatest differentiation was found within, rather than between, populations, although the differentiation value between Mexican and Cuban populations varied in accordance with the geographic distance and ecological characteristic of each. We found a high similarity between these two species with a bimodal distribution of the loci with respect to genetic identity. The homology percentages for gene 16S fragments were compared with those from six different shrimp species (L. vannamei, L. stylirostris, Farfantepenaeus notialis, Metapeneopsis lamellata) and Artemia salina. Ninety-seven percent of identity was found by analysis of a 409 bp of 16S mitochondrial DNA. With these values a phylogenetic tree was made using parsimony criteria. The GDs obtained with this method confirm the classification proposed by Pérez-Farfante & Kensley (1997). [source] A non-sense mutation in the corneodesmosin gene in a Mexican family with hypotrichosis simplex of the scalpBRITISH JOURNAL OF DERMATOLOGY, Issue 6 2005N.O. Dávalos Summary Background, Hypotrichosis simplex of the scalp (HSS; MIM 146520) is a rare autosomal dominant form of non-syndromic alopecia that affects men and women equally. Up to now, only a small number of families with HSS have been reported. The affected individuals experience a diffuse progressing hair loss from childhood to adulthood that is confined to the scalp. Recently, HSS has been mapped to the short arm of chromosome 6 (6p21.3), allowing mutations in the corneodesmosin gene (CDSN) to be identified as the cause of the disorder. To date, two stop mutations have been found in three unrelated families with HSS of different ethnic origin. Objectives, To describe the first HSS-family with Latin American (Mexican) background comprising 6 generations and to identify a mutation in the CDSN gene. Patients/Methods, The patients were examined by a clinician and blood samples were taken. After DNA extraction, sequencing analysis of the CDSN gene and restriction enzyme analysis with PsuI were performed. Results, By direct sequencing of the two exons of the CDSN gene, a nonsense mutation was identified in the index patient in exon 2, resulting in a premature stop codon (Y239X). The mutation cosegregates perfectly in the family with the disease and was not found in 300 control chromosomes using a restriction enzyme analysis with PsuI. Conclusions, A nonsense mutation was identified in the first family with HSS of Latin American ethnical background. Our data provide molecular genetic evidence for a 3rd stop mutation in exon 2 of the CDSN gene being responsible for HSS. All to date known nonsense mutations responsible 3 for HSS are clustered in a region of 40 amino acids which is in accordance with a dominant negative effect conferred by aggregates of truncated CDSN proteins. [source] Disclosure to Parents About Everyday Activities Among American Adolescents From Mexican, Chinese, and European BackgroundsCHILD DEVELOPMENT, Issue 5 2009Jenny P. Yau Disclosure to parents and reasons for not disclosing different activities were examined in 489 Chinese, Mexican, and European American adolescents (M = 16.37 years, SD = 0.77). With generational status controlled, Chinese American adolescents disclosed less to mothers about personal and multifaceted activities than European Americans and less about personal feelings than other youth, primarily because these acts were considered personal, not harmful, or because parents would not listen or understand. Disclosure regarding prudential behavior was lower among Mexican American than among European American adolescents, primarily due to concerns with parental disapproval. Multigroup path analyses indicated that greater closeness to parents is associated with more disclosure for all youth and activities; associations between family obligation and disclosure varied by domain and ethnicity. [source] CONSUMING CLASS: Multilevel Marketers in Neoliberal MexicoCULTURAL ANTHROPOLOGY, Issue 3 2008PETER S. CAHN ABSTRACT Since the 1980s, Mexican leaders have followed other Latin American countries in pursuing neoliberal economic policies designed to stimulate foreign investment, reduce public spending, and promote free trade. Recent studies of indigenous movements and popular protests challenge the idea that these market-based economic reforms enjoy a broad consensus and suggest that elites impose them by force. By turning the focus to middle-class Mexicans, I argue that some nonelite sectors of society avidly welcome the reign of the free market. Although they do not profit directly from unregulated capitalism, the middle class looks to neoliberalism to ensure access to the material markers of class status. The rising popularity of multilevel marketing companies in Mexico, which glorify consumption and celebrate the possibilities of entrepreneurship, demonstrates the appeal of neoliberalism to citizens fearful of diminished purchasing power. By tying consumption to globalized free markets, neoliberalism does not need coercion to win acceptance. [source] Assessing horizontal equity in medication treatment among elderly Mexicans: which socioeconomic determinants matter most?HEALTH ECONOMICS, Issue 10 2008Jürgen Maurer Abstract Many low- and middle-income countries are currently undergoing a dramatic epidemiological transition, with an increasing disease burden due to degenerative noncommunicable diseases. Inexpensive medication treatment often represents a cost-effective means to prevent, control or cure many of these health conditions. Using micro-data from the 2001 Mexican Health and Aging Study, we assess horizontal inequity in medication treatment among older Mexicans before the introduction of Popular Health Insurance in Mexico. In doing so, we investigate the role of various dimensions of socioeconomic status for obtaining indicated medication treatment within a comparatively fragmented health-care system that features relatively high out-of-pocket expenditures. Our empirical analysis suggests health insurance coverage as a key socioeconomic determinant of indicated medication use with large and statistically significant positive effects on take-up. The effects of insurance status thereby clearly dominate any other possible effects of socioeconomic status on medication treatment. Our results thus highlight the importance of access to reliable health care and comprehensive coverage for rational medication use in the management of degenerative diseases. In light of this evidence, we expect that recent Mexican health-care reforms, which expand health insurance coverage to the previously uninsured population, will alleviate socioeconomic gradients in medication treatment among older people in need.

[source] A panel of ancestry informative markers for estimating individual biogeographical ancestry and admixture from four continents: utility and applications,HUMAN MUTATION, Issue 5 2008Indrani Halder Abstract Autosomal ancestry informative markers (AIMs) are useful for inferring individual biogeographical ancestry (I-BGA) and admixture. Ancestry estimates obtained from Y and mtDNA are useful for reconstructing population expansions and migrations in our recent past but individual genomic admixture estimates are useful to test for association of admixture with phenotypes, as covariate in association studies to control for stratification and, in forensics, to estimate certain overt phenotypes from ancestry. We have developed a panel of 176 autosomal AIMs that can effectively distinguish I-BGA and admixture proportions from four continental ancestral populations: Europeans, West Africans, Indigenous Americans, and East Asians. We present allele frequencies for these AIMs in all four ancestral populations and use them to assess the global apportionment of I-BGA and admixture diversity among some extant populations. We observed patterns of apportionment similar to those described previously using sex and autosomal markers, such as European admixture for African Americans (14.3%) and Mexicans (43.2%), European (65.5%) and East Asian affiliation (27%) for South Asians, and low levels of African admixture (2.8,10.8%) mirroring the distribution of Y E3b haplogroups among various Eurasian populations. Using simulation studies and pedigree analysis we show that I-BGA estimates obtained using this panel and a four-population model has a high degree of precision (average root mean square error [RMSE]=0.026). Using ancestry,phenotype associations we demonstrate that a large and informative AIM panel such as this can help reduce false-positive and false-negative associations between phenotypes and admixture proportions, which may result when using a smaller panel of less informative AIMs. Hum Mutat 29(5), 648,658, 2008. © 2008 Wiley-Liss, Inc. [source] Immigration Policy and Employment Conditions of US Immigrants from Mexico, Nicaragua, and the Dominican Republic1INTERNATIONAL MIGRATION, Issue 5 2005Katharine M. Donato ABSTRACT Prior studies suggest that the passage of the Immigration Reform and Control Act (IRCA) in 1986 signalled a deterioration in the labour market conditions of Mexican migrants. In this paper, we examine whether and how labour market conditions worsened for Dominicans and Nicaraguans after 1986, and the extent to which these shifts were comparable to those experienced by Mexicans. Our analysis relies on a new source of data that offers comparable data across the three national origins. We estimate multivariate models that capture the effects of demographic attributes, human and social capital, migration-specific human and social capital, legal status, period of trip, national origin, and other controls on the hourly wages earned by household heads and whether they received cash wages on their last US trip. Models with interaction terms reveal significant pre- and post-1986 wage effects, but few differences in these effects between Mexicans and Dominicans or Nicaraguans. In contrast, group differences appear in the risk of cash receipt of wages. Dominicans and Nicaraguans experienced a greater increase in this risk relative to Mexicans pre- and post-1986. Together, these findings depict a broader, negative impact of IRCA on Latino migrant wages than has been documented elsewhere. [source] He Came, He Saw, He Stayed.INTERNATIONAL MIGRATION, Issue 2 2000Guest Worker Programmes, the Issue of Non-Return Critics of guest worker programmes have pointed out that many temporary workers do not return home when their contracts expire and thus end up swelling the ranks of undocumented workers in a host country. This article argues that this outcome is not inevitable. Whether or not guest workers return home or stay behind depends to a large extent on how the guest worker programme is administered. By comparing the US Bracero Program with the Canadian Mexican Agricultural Seasonal Workers' Program, it is shown that three aspects of programme administration account for why so many Braceros stayed in the US illegally, while almost all temporary workers employed in Canada return to Mexico at the end of the season. The three aspects are recruitment policies and procedures, enforcement of employment and housing-related minimum standards, and the size of the programme. It is suggested that the administration of the programme, in turn, reflects various interests that shape the State's position on foreign labour. Whereas in the US the Bracero Program was tailored to meet the needs of agribusinesses, the Canadian state responds to a wider variety of interests, including its own concern with the definition of ideal citizenship, as well as the need to protect domestic workers and the Mexican Government's interest in assisting those who are most needy. Additionally, unlike the US, where braceros were employed mainly in agribusinesses, in Canada Mexicans are brought to work on family farms. While desertion was a frequent phenomenon in the US, the paternalistic relationships that Canada-bound workers develop with their employers make desertion unlikely. [source] Transnational Twist: Pecuniary Remittances and the Socioeconomic Integration of Authorized and Unauthorized Mexican Immigrants in Los Angeles County,INTERNATIONAL MIGRATION REVIEW, Issue 1 2005Enrico A. Marcelli Annual U.S.-Mexico pecuniary remittances are estimated to have more than doubled recently to at least $10 billion - augmenting interest among policymakers, financial institutions, and transnational migrant communities concerning how relatively poor expatriate Mexicans sustain such large transfers and the impact on immigrant integration in the United States. We employ the 2001 Los Angeles County Mexican Immigrant Residency Status Survey (LAC-MIRSS) to investigate how individual characteristics and social capital traditionally associated with integration, neighborhood context, and various investments in the United States influenced remitting in 2000. Remitting is estimated to have been inversely related to conventional integration metrics and influenced by community context in both sending and receiving areas. Contrary to straight-line assimilation theories and more consistent with a transnational or nonlinear perspective, however, remittances are also estimated to have been positively related to immigrant homeownership in Los Angeles County and negatively associated with having had public health insurance such as Medicaid. [source] Diabetes Mellitus in a Subgroup of Older Mexicans: Prevalence, Association with Cardiovascular Risk Factors, Functional and Cognitive Impairment, and MortalityJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 1 2002Joel Rodríguez-Saldaña MD OBJECTIVES: To examine the prevalence and effects of diabetes mellitus in a subgroup of older Mexicans to allow comparisons to older persons of Mexican origin living in the United States. DESIGN: Longitudinal study. SETTING: High-rise retirement housing in Mexico City. PARTICIPANTS: Seven hundred eighty-five public servants and their family members aged 65 and older. MEASUREMENTS: Geriatric survey of function; mental status and depression; a physical examination; and blood samples for glucose and cholesterol. RESULTS: The prevalence of diabetes mellitus in this population was 15.1%, substantially lower than the prevalence reported in people of Mexican origin living in the United States. Nondiabetics were more obese than diabetics. Diabetes mellitus was more common in men than women. The mortality rate was greater in diabetics than nondiabetics (relative risk = 1.73, P < .05). Diabetics had more coronary artery disease and were more likely to die from myocardial infarction and neoplasms than nondiabetics. Diabetics were more likely to be functionally impaired (P < .0001) but no more likely to fall or to have fractures. Diabetics did not differ from nondiabetics in cognitive impairment or level of dysphoria. CONCLUSION: These studies highlight some important similarities and differences in comparing a middle class subgroup of older diabetics in Mexico City with diabetics of Mexican origin living in the United States.

Basado en investigaciones etnográficas en Chicago, una de las pocas ciudades donde los mexicanos y puertorriqueños han residido por décadas, este estudio analiza las relaciones socio-políticas entre puertorriqueños y migrantes mexicanos y entre cada grupo y el estado-nación estadounidense. La investigación cuestiona la función de la ciudadanfa estadounidense como institutión que produce desigualdad social y subordinatión racial dentro del marco del nacionalismo como formación racial en los Estados Unidos.
