Malamud Abstract Landslides are generally associated with a trigger, such as an earthquake, a rapid snowmelt or a large storm. The landslide event can include a single landslide or many thousands. The frequency,area (or volume) distribution of a landslide event quanti,es the number of landslides that occur at different sizes. We examine three well-documented landslide events, from Italy, Guatemala and the USA, each with a different triggering mechanism, and ,nd that the landslide areas for all three are well approximated by the same three-parameter inverse-gamma distribution. For small landslide areas this distribution has an exponential ,roll-over' and for medium and large landslide areas decays as a power-law with exponent -2·40. One implication of this landslide distribution is that the mean area of landslides in the distribution is independent of the size of the event. We also introduce a landslide-event magnitude scale mL = log(NLT), with NLT the total number of landslides associated with a trigger. If a landslide-event inventory is incomplete (i.e. smaller landslides are not included), the partial inventory can be compared with our landslide probability distribution, and the corresponding landslide-event magnitude inferred. This technique can be applied to inventories of historical landslides, inferring the total number of landslides that occurred over geologic time, and how many of these have been erased by erosion, vegetation, and human activity. We have also considered three rockfall-dominated inventories, and ,nd that the frequency,size distributions differ substantially from those associated with other landslide types. We suggest that our proposed frequency,size distribution for landslides (excluding rockfalls) will be useful in quantifying the severity of landslide events and the contribution of landslides to erosion.

[source] Alcohol in Mayan Guatemala: consumption, distribution, production and composition of cuxaADDICTION, Issue 5 2009Fotis Kanteres ABSTRACT Aims To describe the consumption, distribution, production and chemical composition of alcohol, including cuxa (pronounced ,coo sha'), in Nahualá, a highland Mayan municipality in Guatemala. Cuxa is a sugarcane-derived spirit, in part produced clandestinely, that has been distributed in the community for several decades. Methods Key informant interviews with alcohol distributors and consumers, cuxa producers and health professionals, as well as analyses of questionnaires from a sample of 47 spouses who came to the local health centre for problems related to their husband's drinking. Sampling and chemical analysis of cuxa from 12 of 13 identified sales points in the head-town of Nahualá and its nearby settlements (10 km radius). Fieldwork was conducted between November 2007 and March 2008. Results Alcohol consumption was found to be integrated culturally in this community. The overall drinking culture was marked by irregular heavy drinking occasions, especially around market days, with substantial inebriation and health problems, especially among street inhabiting drinkers. Cuxa contributed to these problems, and cuxa drinking was socially stigmatized. Cuxa was produced both clandestinely and industrially, and sold legally by taverns and illegally by clandestine distributors. The alcoholic strength of the samples was typically between 17 and 19% vol.; clandestinely produced cuxa samples showed acetaldehyde contamination. Conclusions Measures should be taken to reduce the harm associated with alcohol in this community, including efforts to reduce acetaldehyde levels in cuxa. [source] Carcinogenicity of acetaldehyde in alcoholic beverages: risk assessment outside ethanol metabolismADDICTION, Issue 4 2009Dirk W. Lachenmeier ABSTRACT Aims In addition to being produced in ethanol metabolism, acetaldehyde occurs naturally in alcoholic beverages. Limited epidemiological evidence points to acetaldehyde as an independent risk factor for cancer during alcohol consumption, in addition to the effects of ethanol. This study aims to estimate human exposure to acetaldehyde from alcoholic beverages and provide a quantitative risk assessment. Methods The human dietary intake of acetaldehyde via alcoholic beverages was estimated based on World Health Organization (WHO) consumption data and literature on the acetaldehyde contents of different beverage groups (beer, wine, spirits and unrecorded alcohol). The risk assessment was conducted using the European Food Safety Authority's margin of exposure (MOE) approach with benchmark doses obtained from dose,response modelling of animal experiments. Life-time cancer risk was calculated using the T25 dose descriptor. Results The average exposure to acetaldehyde from alcoholic beverages was estimated at 0.112 mg/kg body weight/day. The MOE was calculated to be 498, and the life-time cancer risk at 7.6 in 10 000. Higher risk may exist for people exposed to high acetaldehyde contaminations, as we have found in certain unrecorded alcohol beverages in Guatemala and Russia, for which we have demonstrated possible exposure scenarios, with risks in the range of 1 in 1000. Conclusions The life-time cancer risks for acetaldehyde from alcoholic beverages greatly exceed the usual limits for cancer risks from the environment set between 1 : 10 000 and 1 : 1 000 000. Alcohol consumption has thus been identified as a direct source of acetaldehyde exposure, which in conjunction with other sources (food flavourings, tobacco) results in a magnitude of risk requiring intervention. An initial public health measure could be to reduce the acetaldehyde content in alcoholic beverages as low as technologically possible, and to restrict its use as a food flavour additive. [source] Teaching and Learning with Therapists Who Work with Street Children and Their FamiliesFAMILY PROCESS, Issue 3 2010JANINE ROBERTS ED.D. Providing training for people working with some of the most marginalized families in Guatemala and Peru meant establishing credibility as a facilitator; entering organizations as a learner; cocreating training agendas; and working in a format that paralleled a strength-based, resilience focus in therapy. Strategies used for different phases of the work are detailed: multiple ways to gather information, shadowing staff, delivering topics on demand, and creating learning environments with a focus on families as teachers. Key processes included moving in and out of the role of facilitator and participant, entering into the trainings from different vantage points within the organizations, and designing activities with an eye to how they would impact work relationships of staff and clients. RESUMEN Brindar capacitación a personas que trabajan con algunas de las familias más marginadas de Guatemala y Perú implicó establecer credibilidad como facilitador; ingresar en organizaciones como alumno; co-crear agendas de capacitación y trabajar en un formato análogo a un enfoque basado en las virtudes y la resiliencia en terapia. Se detallan las estrategias utilizadas en las diferentes fases del trabajo: distintas maneras de reunir información, observación del personal, charlas a pedido, y creación de ambientes de aprendizaje haciendo hincapié en las familias como maestras. Los procesos clave consistieron en asumir y abandonar el rol de facilitador y participante, iniciar las capacitaciones desde diferentes posiciones de ventaja dentro de las organizaciones y diseñar actividades con miras a cómo repercutirían sobre las relaciones laborales del personal y los clientes.

A. BARRIENTOS Abstract, Fish community composition was assessed among six macrophyte habitats, including hydrilla, Hydrilla verticillata (L.F.) Royle, common native species (bulrush, Scirpus spp., muskgrass, Chara spp., eelgrass, Vallisneria americana Michx. and Illinois pondweed, Potamogeton illinoensis Morong) and no-plants, to assess potential impacts of recent hydrilla colonisation on the littoral fish community at Lake Izabal, Guatemala. Fish biomass was significantly different among habitats, with hydrilla supporting the highest fish biomass. Fish density did not differ significantly among habitats. Total fish species richness was similar (12-15 species) among habitats, but community composition changed with macrophyte presence. Biomass of mojarra, Cichlasoma maculicauda Regan, which supported the most important subsistence fishery at the lake, was significantly different among habitats and had the greatest biomass in the hydrilla habitat. Although hydrilla may adversely affect native plants, lake access and other uses, it provided useful fish habitat and likely was not detrimental to the Lake Izabal fish community composition. [source] Stable carbon isotope signature of ancient maize agriculture in the soils of Motul de San José, GuatemalaGEOARCHAEOLOGY: AN INTERNATIONAL JOURNAL, Issue 3 2007Elizabeth A. Webb Soil profiles collected from a 2.5-km transect radiating from the Maya center of Motul de San José were analyzed for the stable carbon-isotope composition of their soil organic matter. The residues of maize (Zea mays), the only C4 plant known to have been cultivated in this area by the ancient Maya, impart a carbon-isotope signature to the underlying soil organic matter reservoir that is distinct from that produced by the native C3 forest vegetation. The varying turnover rates of the humic acid and humin fractions of the soil organic matter allowed us to distinguish between the presence of modern and ancient maize residues in these soils, and to delineate the lateral extent of maize cultivation at this ancient Maya site. The strongest isotopic evidence of maize residues is preserved in the soils surrounding the peripheral settlement of Chäkokot and at one locality within the urban center of Motul de San José. © 2007 Wiley Periodicals, Inc. [source] Application of carbon isotope analysis to ancient maize agriculture in the Petexbatún region of GuatemalaGEOARCHAEOLOGY: AN INTERNATIONAL JOURNAL, Issue 3 2007Kristofer D. Johnson The ancient Maya subsisted in an environment limited by shallow soils and unpredictable weather patterns until their collapse ,A.D. 800,900. Ancient subsistence can be a difficult subject, with little physical evidence of agricultural artifacts and structures. This study characterized soil profiles and utilized changes in stable carbon isotope ratios of soil organic matter (SOM) to locate and interpret areas of ancient C4 plant growth and maize (Zea mays) cultivation among the Maya. The investigation indicated some of the challenges the Maya faced, including shallow and sloped soils in some areas. The C4 plant signature was found in seasonal wetland soils on the opposite side of the Laguneta Aguateca from the ruins of Aguateca, but not in the perennial wetlands on the immediate side. No C4 plant signature was detected in the shoulder and backslope soils. Based on these findings, the ancient Maya of Aguateca probably adapted to their environment by farming rich toeslope soils. It is possible that maize was also grown in the seasonal wetlands adjacent to the site. If the steep backslope soils around Aguateca were used in ancient agriculture, the evidence has probably eroded away. © 2007 Wiley Periodicals, Inc. [source] An ethnoarchaeological study of chemical residues in the floors and soils of Q'eqchi' Maya houses at Las Pozas, GuatemalaGEOARCHAEOLOGY: AN INTERNATIONAL JOURNAL, Issue 6 2002Fabián G. Fernández This ethnoarchaeological study at the Q'eqchi' Maya village of Las Pozas, Guatemala, aimed to refine the understanding of the relationship between soil chemical signatures and human activities for archaeological applications. The research involved phosphorus, exchangeable ion (calcium, potassium, magnesium, sodium), and trace element analysis of soils and earth floors extracted by Mehlich II, ammonium acetate, and DTPA chelate solutions, respectively. The results showed high levels of phosphorus, potassium, magnesium, and pH in food preparation areas, as well as high phosphorus concentrations and low pH in food consumption areas. The traffic areas exhibited low phosphorus and trace element contents, whereas refuse disposal areas were enriched. These results provide important information for the understanding of space use in ancient settlements. © 2002 Wiley Periodicals, Inc. [source] Using in-field phosphate testing to rapidly identify middens at Piedras Negras, GuatemalaGEOARCHAEOLOGY: AN INTERNATIONAL JOURNAL, Issue 8 2001J. Jacob Parnell Recent studies have promoted using soil phosphate analysis to detect ancient Maya sites by delimiting areas of occupation based on decomposed organic matter. Refuse associated with human activity increases organic matter around areas of ancient human habitation. Theoretically, the highest concentration of organic matter,detectable by phosphate analysis,should be directly associated with areas of refuse disposal. Thus, the objective of this study is to investigate the potential of phosphate analysis to detect residential middens in Piedras Negras, Guatemala. This paper presents the results of a sensitive, in-field phosphate analysis method applied as a midden prospection tool in residential areas. Phosphate concentration is correlated with artifact data obtained from a total of 37 test pits excavated in areas of varying phosphate concentration in three residential sites. A positive correlation between phosphate concentration and ceramic density indicates the potential of this method in defining and orienting excavations of residential areas. © 2001 John Wiley & Sons, Inc. [source] PUBLIC MEMORY AND POLITICAL POWER IN GUATEMALA'S POSTCONFLICT LANDSCAPEGEOGRAPHICAL REVIEW, Issue 4 2003MICHAEL K. STEINBERG ABSTRACT. Landscape interpretation, or "reading" the landscape, is one of cultural geography's standard practices. Relatively little attention, however, has been paid to reading landscapes transformed by insurgency movements or civil wars. Those landscapes can tell us a great deal about past and present political and social relationships as well as continuing power struggles. Guatemala presents a complicated postwar landscape "text" in which the struggle for power continues by many means and media, including how the war is portrayed on memorials, and in which the Catholic Church and the military/state are the two main competing powers. This essay explores some of the images and the text presented in Guatemala's postconflict landscape through contrasting landmarks and memorials associated with the country's thirty-six-year-long civil war that formally ended in 1996. [source] Deformation history of the eclogite- and jadeitite-bearing mélange from North Motagua Fault Zone, Guatemala: insights in the processes of a fossil subduction channelGEOLOGICAL JOURNAL, Issue 2 2009Michele Marroni Abstract In Guatemala, along the northern side of the Motagua Valley, a mélange consisting of blocks of eclogite and jadeitite set in a metaserpentinitic and metasedimentary matrix crops out. The metasedimentary rocks display a complex deformation history that includes four tectonic phases, from D1 to D4. The D1 phase occurs only as a relic and is characterized by a mineral assemblage developed under pressure temperature (P,T) conditions of 1.00,1.25,GPa and 206,263°C. The D2 phase, characterized by isoclinal folds, schistosity and mineral/stretching lineation, developed at P,T conditions of 0.70,1.20,GPa and 279,409°C. The following D3 and D4 phases show deformations developed at shallower structural levels. Whereas the D1 phase can be interpreted as the result of underplating of slices of oceanic lithosphere during an intraoceanic subduction, the following phases have been acquired by the mélange during its progressive exhumation through different mechanisms. The deformations related to the D2 and D3 phases can be regarded as acquired by extrusion of the mélange within a subduction channel during a stage of oblique subduction. In addition, the structural evidences indicate that the coupling and mixing of different blocks occurred during the D2 phase, as a result of flow reverse and upward trajectory in the subduction channel. By contrast, the D4 phase can be interpreted as related to extension at shallow structural levels. In this framework, the exhumation-related structures in the mélange indicate that this process, probably long-lived, developed through different mechanisms, active in the subduction channel through time.

[source] The Latinization of the Central Shenandoah ValleyINTERNATIONAL MIGRATION, Issue 1 2008Laura Zarrugh Virginia is among a number of southern states in the United States, such as North Carolina, Arkansas and Georgia, which have experienced a sudden growth in Latino immigration during the past decade. Not only is the volume of growth unprecedented, but many of the destinations are new and located in rural areas. Places that have not hosted immigrant populations for generations are quickly becoming multicultural. The small city of Harrisonburg (population 43,500 according to the 2005 estimate), which is located in the rural Central Shenandoah Valley of Virginia, is perhaps the premier example of this new pattern of change. While local advertising once promoted Harrisonburg for its "99.2% American-born and 93.7% white" population, the area today holds the distinction of hosting the most diverse public school enrollment in the state (in 2006-2007), with students from 64 countries who speak 44 languages. Among them are Spanish speakers from at least 14 different countries. Drawing on social network theory, the paper examines how social networks among Latino immigrants become activated in new settlement areas. It presents a case history of the historic process of "Latinization" involving the settlement of a number of diverse Latino populations (from Mexico, Guatemala, El Salvador, Honduras, Cuba and Uruguay) in Harrisonburg and the surrounding Central Shenandoah Valley. The study demonstrates how a number of key institutions, including local agricultural industries (apples and poultry), a refugee resettlement office and churches recruited "pioneers" from these immigrant groups to the area and how "pioneers" subsequently engaged in further social network recruitment, thus creating multiple transnational "daughter communities" in the Harrisonburg area. The policy implications of this historical process are explored. Au même titre que la Caroline du Nord, l'Arkansas et la Georgie, la Virginie est l'un de ces Etats du sud des Etats-Unis qui ont été témoins d'une poussée soudaine de l'immigration latino-américaine au cours de la dernière décennie. Non seulement il s'agit d'un rythme de croissance sans précédent, mais bon nombre de destinations choisies sont nouvelles et situées en zone rurale. Des lieux qui n'avaient pas accueilli de population immigrée depuis des générations prennent brusquement un caractère multiculturel. La petite ville de Harrisonburg (43 500 habitants selon un décompte approximatif de 2005), qui est située dans la vallée centrale de Shenandoah, en Virginie, est peut-être le principal exemple de cette nouvelle évolution. Alors qu'elle se vantait autrefois d'être composée d'Américains de souche à hauteur de 99,2% et d'être blanche à 93,7%, cette ville se distingue aujourd'hui par la plus grande diversité d'origine des enfants scolarisés à l'échelle de l'Etat (pour la période 2006-2007), puisqu'on y dénombre 64 nationalités parlant 44 langues. On y trouve notamment des hispanophones originaires d'au moins 14 pays différents. A partir de la théorie des réseaux sociaux, l'auteur examine comment ces réseaux se sont activés chez les immigrants latino-américains dans les nouvelles zones d'installation. Il présente un historique du processus de "latinisation", en citant notamment l'installation de populations latino-américaines diverses (originaires du Mexique, du Guatemala, d'El Salvador, du Honduras, de Cuba et d'Uruguay) à Harrisonburg et dans la vallée centrale Shenandoah entourant cette ville. L'auteur montre comment un certain nombre d'institutions clés, et notamment les industries agricoles locales (pommeraies et élevages de poulets), un bureau de réinstallation de réfugiés et des églises ont recruté des "pionniers" au sein de ces groupes d'immigrants, et comment ces "pionniers" ont par la suite poursuivi cette action de recrutement à l'aide de réseaux sociaux, créant ainsi de multiples "communautés affiliées" transnationales dans la région de Harrisonburg. L'étude examine aussi les implications politiques de ce processus historique. Virginia es uno de los estados sureños de los Estados Unidos, al igual que Carolina del Norte, Arkansas y Georgia, que ha experimentado un incremento repentino de la inmigración latina durante el último decenio. No sólo se trata de un incremento sin precedentes, si no que además los destinos son nuevos y localizados en zonas rurales. Estos lugares que no han albergado a poblaciones inmigrantes durante generaciones se están convirtiendo rápidamente en entornos multiculturales. La pequeña ciudad de Harrisonburg (con 43.500 habitantes según el censo de 2005), está localizada en el valle rural central de Shenadoah en Virginia, y es quizás el primer ejemplo de este nuevo patrón de cambio. Si bien la publicidad local promocionaba a Harrisonburg porque sus habitantes eran "99,2 por ciento nacidos en América y 93,7 por ciento blancos" hoy en día se destaca por albergar la población más diversa inscrita en los colegios públicos del Estado (entre 2006 y 2007), con estudiantes provenientes de 64 países que hablan 44 idiomas. Entre ellos están estudiantes de habla hispana provenientes de por lo menos 14 países distintos. Sobre la base de la teoría de redes sociales, este artículo examina redes sociales entre los inmigrantes latinos que se activan en nuevas zonas de asentamiento. Se presenta un estudio por caso de un proceso histórico de "latinización" que implica el asentamiento de toda una variedad de poblaciones latinas de "México, Guatemala, El Salvador, Honduras, Cuba y Uruguay" en Harrisonburg y el valle central aledaño de Shenandoah. El estudio demuestra cómo una serie de instituciones clave,- incluidas las industrias agrícolas locales (manzanos y avicultura), una oficina de reasentamiento de refugiados y las iglesias - reclutaron a los "pioneros" de estos grupos de inmigrantes en la región y cómo esos "pioneros" entablaron ulteriormente el reclutamiento a nivel de su red social, creando "comunidades hermanas" transnacionales y múltiples en la región de Harrisonburg. También se examinan las repercusiones políticas de este proceso histórico. [source] Social Protection and the Labour Market in Latin America: What can be Learned from Household Surveys?INTERNATIONAL SOCIAL SECURITY REVIEW, Issue 2-3 2005Leonardo Gasparini Most social protection is provided through contribution-based programmes, which means that protection is usually linked to employment conditions in the formal economy. This article describes the levels, trends and structure of social protection for workers in Latin America, highlighting the relationship between protection and employment conditions. The study is based on a selection of household surveys carried out in various countries in the region: Argentina, Brazil, Bolivia, Chile, Ecuador, Guatemala, Mexico, Nicaragua and Peru. It emphasizes the usefulness of household surveys as sources of information for representative studies on social protection and employment, in spite of the problems of coverage and comparability that they raise. [source] Catholic and Non-Catholic Theologies of Liberation: Poverty, Self-Improvement, and Ethics Among Small-Scale Entrepreneurs in Guatemala CityJOURNAL FOR THE SCIENTIFIC STUDY OF RELIGION, Issue 1 2002Henri Gooren In the late 1960s and early 1970s, Catholic liberation theology seemed poised to become a mass movement in Latin America, whereas evangelical Protestantism did not seem likely to ever receive broad popular appeal. This paper will explore possible reasons why most of the poor in Latin America preferred to join non-Catholic churches, instead of the so-called Christian Base Communities (CEBs) or other grassroot groups connected with liberation theology. It does so by a review of scientific literature and by presenting empirical data from field research in Guatemala City. Using a neo-Weberian approach, I will argue that various non-Catholic churches foster elements of asceticism and self-improvement, which provide an important asset for the poor in Guatemala in their quest to better their lives both economically and spiritually.

The objective of this initiative was not only to improve outcomes in the parent,child relationship, but to galvanize the formation of community-based support groups that could have multiple ends. The theoretical foundations of the project are introduced, before illustrating their practical application. Sixteen months post-intervention, largely positive effects were being sustained in parent child relations. The project was also successful in generating social action through the formation of grass-roots women's organizations. Copyright © 2008 John Wiley & Sons, Ltd. [source] Expectations and motivations of Hondurans migrating to the United StatesJOURNAL OF COMMUNITY & APPLIED SOCIAL PSYCHOLOGY, Issue 3 2007Jana Sladkova Abstract This study explores the expectations and decision-making processes of potential migrants at a community in Honduras. Hondurans have become one of the fastest growing populations in New York. Yet, although approximately 80,000 Hondurans try to reach the US annually, only 25 per cent succeed. To reach the United States they must undergo a dangerous journey across Guatemala and Mexico, a process to date under-researched by social sciences. As new undocumented migrant streams continue to expand within the global economies, scholars and practitioners who work on their behalf should understand the pre-migration values and expectations because they shape the way migrants adjust to and develop new cultural patterns in the receiving countries. Drawing on immigration and narrative theory, I hypothesize that narratives of migration from media, prior migrants, coyotes and community practices play an important role in the construction of potential migrant expectations. To represent narratives across several individual and community domains, the research design includes individual interviews, analysis of local newspapers, participant observations and teaching English classes. Analysis across these data reveals complex dilemmas potential migrants face as they weigh the costs and benefits of migration. Copyright © 2007 John Wiley & Sons, Ltd. [source] Hydroa-like lymphoma with CD56 expressionJOURNAL OF CUTANEOUS PATHOLOGY, Issue 5 2008Katherine Doeden Hydroa-like lymphoma is an extremely rare and aggressive lymphoma described in children from Latin American countries (Mexico, Guatemala and Peru) and Asia (Japan, Korea and Taiwan). Clinically, patients present with vesicles, ulcers and scars occurring on both sun-exposed and non-sun-exposed areas. In contrast to classical hydroa vacciniforme, hydroa-like lymphoma is associated with systemic lymphoma of T-cell type that expresses either CD4 or CD8. We report the findings from two unusual cases of hydroa-like lymphoma that, unlike the cases described thus far in the literature, express CD56 and resemble natural killer cell lymphomas. Two 9-year-old boys presented with clinical histories of waxing and waning ulcerative blistering lesions since 3 years of age. Histological examination of skin biopsies from both cases showed periappendigeal infiltrates of atypical lymphocytes. Immunohistochemical studies showed that the cells were highlighted by markers for CD3, CD56 and CD30, but did not express CD4 and CD8. Both patients were alive with disease 1 year later. Hydroa-like lymphoma with natural killer-cell phenotype may have a similar outcome to T-cell derived hydroa-like lymphoma, but the prognosis appears to be better than classic NK lymphomas, which in general behave in an aggressive fashion. [source] Newborn screening in Fragile X syndromeJOURNAL OF INTELLECTUAL DISABILITY RESEARCH, Issue 10 2008F. Tassone Background: Screening for the FMR1 mutations has been a topic of considerable discussion since the FMR1 gene was identified. However, Fragile X has not been recommended for newborn screening mainly because of the lack of an accurate screening test and of data on potential benefits. We have recently developed an improved Polymerase Chain Reaction (PCR) method for the identification of premutation and full mutation alleles for the FMR1 gene. Method: The method is inexpensive, accurate and quick and can be performed on a number of sample templates including, importantly, blood spots. We have applied this method for international screening. Specifically, we have screened 5267 anonymous blood spot samples from newborn males from the centre-northwest region of Spain. We have also used this technology to a pilot ,high risk' screening program of individuals with autism and/or intellectual disabilities and family members of a proband with fragile X initiated in Guatemala. This project is a prototype for future screening endeavours. Results: One important outcome from this study is that the frequency of premutation alleles (1 per 250) appears to be higher than previously reported. This is of importance, especially in view of the different phenotypic involvement observed in carriers of premutation alleles, including neurological problems such as FXTAS. Here, we present data on the frequency of premutation/full alleles found in this population and their size distribution. Conclusion: This project is a prototype for future screening endeavours. Results from our pilot program in both Spain and Guatemala will lend strong support for implementing this technology for rapid screening to a much larger scale population screening. [source] Maquila Age Maya: Changing Households and Communities of the Central Highlands of GuatemalaJOURNAL OF LATIN AMERICAN & CARIBBEAN ANTHROPOLOGY, Issue 1 2001Liliana R. Goldín As rural peoples of Central America and beyond struggle to create and access new forms of market participation and means of survival under the conditions generated by structural adjustment policies, significant social and cultural shifts are taking place at the local level. This paper analyzes on three levels the impact of maquiladora industries: the region and communities, sending households, and individuals. In particular, I address the implications of migration and urbanization for the new communities, the complex nature of diversified households, and attitudes toward industrial and agricultural work. I conclude with a discussion about the implications of these findings for transitions to proletarianization. [source] Language loss in Guatemala: A statistical analysis of the 1994 population censusJOURNAL OF SOCIOLINGUISTICS, Issue 1 2005Richard John Hawkins This study examines several approaches linguists have taken to explain native language attrition. Five attitudinal factors linked to ethnolinguistic vitality are examined: minority status, access to, and participation in, institutions and markets, cultural strength, education, and migration. Each factor was quantified into proxy variables using information compiled from the 1994 Guatemalan national population census. After constructing the data set, the author used regression analysis of the proxy variables to determine the significance of each attitudinal factor. Minority status, participation in institutions and markets, education, and migration all showed statistically significant correlations with language attrition among Maya speakers in Guatemala. Cultural strength, however, did not show a statistically significant correlation to language loss in the country. [source] Horizontal Accountability in Transitional Democracies: The Human Rights Ombudsman in El Salvador and GuatemalaLATIN AMERICAN POLITICS AND SOCIETY, Issue 4 2004Michael Dodson ABSTRACT Postwar El Salvador and Guatemala have undertaken to reform and democratize the state and to support the rule of law. Each country entered the 1990s hobbled by a legacy of authoritarian rule, while a corrupt and politicized judiciary offered virtually no check on the abuse of power. Because the judiciary has performed poorly as an institution of horizontal accountability, this article examines the performance of a new "accountability agency," the Human Rights Ombudsman. The article discusses the context in which the office was established and developed in each country, perceptions of its performance, and political responses as the office began to perform its function of holding public officials accountable in their exercise of power. Unfortunately, this new office may fall prey to the same weaknesses that have plagued older institutions in both countries. [source] The Uneven Performance of Third Wave Democracies: Electoral Politics and the Imperfect Rule of Law in Latin AmericaLATIN AMERICAN POLITICS AND SOCIETY, Issue 3 2002Joe Foweraker ABSTRACT This article investigates the performance of the new democracies of the third wave by developing a conceptual model of the core elements of liberal democratic government and by constructing a new Database of Liberal Democratic Performance. The performance is shown to be uneven in two main ways. First, the institutional attributes of democratic government advance while individual and minority rights languish. Second, particular institutional attributes coexist uncomfortably, as do particular rights. A comparison of Brazil, Colombia, and Guatemala complements the big picture drawn from the database and focuses on the specific contextual conditions that can create the general political contours of the wave. The uneven democratic performance of these cases is mainly explained by the combination of persistent oligarchic power and a largely unaccountable military. Yet uneven performance, and the imperfect rule of law in particular, does not necessarily prevent democratic survival. [source] Learning Disabilities in Guatemala and Spain: A Cross-National Study of the Prevalence and Cognitive Processes Associated with Reading and Spelling DisabilitiesLEARNING DISABILITIES RESEARCH & PRACTICE, Issue 3 2007Juan E. Jiménez The main purposes of this research were twofold. We examined the samenesses about learning disabilities (LD) in Guatemala and Spain, two countries with the same language but cultural, political, and educational differences, first analyzing data about the prevalence of reading and spelling disabilities in Guatemala City and the Spanish region of the Canary Islands. The focus of the second study was to determine whether there are cross-national patterns of significant differences in cognitive processes associated with reading and spelling disabilities from a developmental approach in these two cultural contexts. We found some differences in the prevalence of specific LD in reading between both countries but we did not find significant differences between Guatemalan and Spanish reading-disabled children in cognitive processes that are involved in reading and spelling acquisition in spite of the cultural and educational differences between the two countries. [source] Phylogeographical structure and temporal complexity in American sweetgum (Liquidambar styraciflua; Altingiaceae)MOLECULAR ECOLOGY, Issue 17 2008ASHLEY B. MORRIS Abstract Eastern North American plant biogeography has traditionally focused on two primary issues: (i) the location of temperate Pleistocene refugia and their proximity to the southern margin of the ice sheet during the last glacial maximum, and (ii) the origin of the temperate element of northern Latin America. While numerous population genetic and phylogeographical studies have focused on the first issue, few (if any) have considered the second. We addressed these issues by surveying 117 individuals from 24 populations of Liquidambar styraciflua (American sweetgum; Altingiaceae) across the southeastern USA, eastern Mexico, and Guatemala, using more than 2200 bp of chloroplast DNA sequence data. To specifically address the issue of timing, we estimated intraspecific divergence times on the basis of multiple fossil-based calibration points, using taxa from Altingiaceae (Liquidambar and Altingia) and Hammamelidaceae (Hamamelis) as outgroups. More than half of the sampled localities exhibited multiple haplotypes. Remarkably, the greatest variation was observed within the USA, with Mexico and Guatemala sharing widespread haplotypes with Texas, Mississippi, Kentucky, Ohio, and northern Virginia. This lack of differentiation suggests shared ancestral polymorphisms, and that the genetic signal we observed is older than the disjunction itself. Our data provide support for previously proposed hypotheses of Pleistocene refugia in peninsular Florida and along the eastern Atlantic, but also for deeper divergences (~8 million years ago) within the USA. These patterns reflect a dynamic biogeographical history for eastern North American trees, and emphasize the importance of the inclusion of a temporal component in any phylogeographical study.

JARAMILLO-CORREA Abstract The genus Abies has a complex history in southern México and Guatemala. In this region, four closely related species, Abies flinckii, A. guatemalensis, A. hickelii, and A. religiosa, are distributed in fragmented and isolated montane populations. Range-wide genetic variation was investigated across species using cytoplasmic DNA markers with contrasted inheritance. Variation at two maternally inherited mitochondrial DNA markers was low. All species shared two of the nine mitotypes detected, while the remaining seven mitochondrial DNA types were restricted to a few isolated stands. Mitochondrial genetic differentiation across taxa was high (GST = 0.933), it was not related to the taxonomic identity (amova; P > 0.05) of the populations, and it was not phylogeographically structured (GST , NST). In contrast, variation at three paternally inherited chloroplast DNA microsatellites was high. Chloroplast genetic differentiation was lower (GST = 0.402; RST = 0.547) than for mitochondrial DNA, but it was significantly related to taxonomy (amova; P < 0.001), and exhibited a significant phylogeographical structure (GST < RST). Different analyses of population structure indicated that A. flinckii was the most divergent taxon, while the remaining three species formed a relatively homogeneous group. However, a small number of the populations of these three taxa, all located at the limits of their respective ranges or in the Transverse Volcanic Belt, diverged from this main cluster. These trends suggest that the Mesoamerican Abies share a recent common ancestor and that their divergence and speciation is mainly driven by genetic drift and isolation during the warm interglacial periods.

Pugh ABSTRACT, From initial contact with the Europeans until their conquest (C.E. 1525,1697), the Itza and their political rivals, the Kowoj, dominated Petén, Guatemala. Colonial artifacts at Zacpetén record the initial appropriations of European objects by the Kowoj. All such objects rested in ceremonial contexts, indicating that the Kowoj considered them positive sources of sacred power. The Kowoj were in contact with the Spaniards and knew they were the source of the valued materials; hence, the materials also signified otherness. Social elites frequently retained objects obtained from long distances, even those of oppressive colonial groups, as positive contagion. I argue that the Kowoj incorporated colonial objects into their rites to harness the power of alterity. [source] |
