  1. Oral rabies vaccination in north america: opportunities, complexities, and challenges.

    Directory of Open Access Journals (Sweden)

    Dennis Slate

    Full Text Available Steps to facilitate inter-jurisdictional collaboration nationally and continentally have been critical for implementing and conducting coordinated wildlife rabies management programs that rely heavily on oral rabies vaccination (ORV. Formation of a national rabies management team has been pivotal for coordinated ORV programs in the United States of America. The signing of the North American Rabies Management Plan extended a collaborative framework for coordination of surveillance, control, and research in border areas among Canada, Mexico, and the US. Advances in enhanced surveillance have facilitated sampling of greater scope and intensity near ORV zones for improved rabies management decision-making in real time. The value of enhanced surveillance as a complement to public health surveillance was best illustrated in Ohio during 2007, where 19 rabies cases were detected that were critical for the formulation of focused contingency actions for controlling rabies in this strategically key area. Diverse complexities and challenges are commonplace when applying ORV to control rabies in wild meso-carnivores. Nevertheless, intervention has resulted in notable successes, including the elimination of an arctic fox (Vulpes lagopus rabies virus variant in most of southern Ontario, Canada, with ancillary benefits of elimination extending into Quebec and the northeastern US. Progress continues with ORV toward preventing the spread and working toward elimination of a unique variant of gray fox (Urocyon cinereoargenteus rabies in west central Texas. Elimination of rabies in coyotes (Canis latrans through ORV contributed to the US being declared free of canine rabies in 2007. Raccoon (Procyon lotor rabies control continues to present the greatest challenges among meso-carnivore rabies reservoirs, yet to date intervention has prevented this variant from gaining a broad geographic foothold beyond ORV zones designed to prevent its spread from the eastern US

    Dengue is a systemic arthropod-borne viral disease of major global public health importance. At least 2.5 billion people who live in areas of the world where dengue occurs are at risk of developing dengue fever (DF) and its severe complications, dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). Repeated reemergences of dengue in sudden explosive epidemics often cause public alarm and seriously stress healthcare systems. The control of dengue is further challenged by the lack of effective therapies, vaccines, and point-of-care diagnostics. Despite years of study, even its pathogenic mechanisms are poorly understood. This article discusses recent advances in dengue research and identifies challenging gaps in research on dengue clinical evaluation, diagnostics, epidemiology, immunology, therapeutics, vaccinology/clinical trials research, vector biology, and vector ecology. Although dengue is a major global tropical pathogen, epidemiologic and disease control considerations in this article emphasize dengue in the Americas. PMID:22782946

    Several Latin American countries are setting up biofuel programmes to establish alternative markets for agricultural commodities. This is mainly triggered by the current success of Brazilian bioethanol production for the domestic market and for export. Furthermore, the global biofuel market is expected to increase due to ambitious biofuel programmes in the EU and in the USA. Colombia, Venezuela, Costa Rica and Guatemala are focusing on bioethanol production from sugarcane whereas biofuel production in Argentina is based on soy biodiesel. Recent developments of the biofuel sector take place extremely rapid especially in Argentina, which became one of the five largest biodiesel producers in the world in 2008. Till date no specific biofuel sustainability certification systems have been implemented in Latin American, as well as on global level. This fact and the predominant use of food crops for biofuel production raise concerns about the sustainability of biofuel production related to environmental and social aspects. This paper provides an overview of the hotspots of conflicts in biofuel production in Latin America. It investigates presently available sustainability tools and initiatives to ensure sustainable biofuel production in Latin America. Finally, it provides an outlook on how to integrate sustainability in the Latin American biofuel sector. - Research Highlights: > This study investigates risks and opportunities of biofuels in Latin America. > Latin American countries are setting up programmes to promote biofuel development. > Strong biofuel sectors provide opportunities for economic development. > Potential negative impact includes deforestation and effects on food security. > Sustainability initiatives exist to minimise negative impact.

    2016-01-01

    Dengue has escalated in the region of the Americas unabated despite major investments in integrated vector control and prevention strategies. An effective and affordable dengue vaccine can play a critical role in reducing the human and economic costs of the disease by preventing millions around the world from getting sick. However, there are considerable challenges on the path towards vaccine introduction. These include lack of sufficient financing tools, absence of capacity within national level decision-making bodies, and demands that new vaccines place on stressed health systems. Various financing models can be used to overcome these challenges including setting up procurement mechanisms, integrating regional and domestic taxes, and setting up low interest multilateral loans. In this paper we review these challenges and opportunities of financing dengue vaccine introduction in the Americas.

  8. Indigenous Territories and REDD in Latin America: Opportunity or Threat?

    Directory of Open Access Journals (Sweden)

    Chris van Dam

    2011-03-01

    Full Text Available An important proportion of Latin America’s forests are located in indigenous territories, and indigenous peoples are the beneficiaries of about 85% of the area for which local rights to land and forest have been recognized in Latin America since the 1980s. Nevertheless, many of these areas, whether or not rights have been recognized, are subject to threats from colonists, illegal loggers, mining and oil interests and others, whose practices endanger not only the forests but also indigenous people’s territory as a whole. In this context, REDD could constitute a new threat or intensify others, particularly in places where indigenous tenure rights have not been recognized, but REDD could also offer new opportunities. This article describes the limitations of thinking only in terms of communities, rather than territories, and examines the extent to which REDD has been conceived considering the characteristics of this new territorial configuration. It also identifies the challenges that REDD may face with this new ‘stakeholder’, such as numerous specific characteristics of territories, given their heterogeneity, in the context of past experiences regarding ‘forest options’. This paper analyses the situation in already-titled indigenous territories in particular, and also discusses problems facing territories in the titling process.

    Health systems in South America still support segmentation, privatization and fragmentation. Health reforms of the structural adjustment programs in the 1980s and 1990s in South America followed different purposes and strategies ranging from privatization, commodification and state intervention for the implementation of a national public health service with universal access as a right of the citizens. Since the 2000s, many countries have expanded social policies, reduced poverty and social in...

    Full Text Available This article analyses the impact of the deepening economic relations China and other Asian countries have with the economies of Latin America. It looks at the main benefits and costs of this greater interaction with particular reference to Latin America’s capacity for growth in the short and medium term. To this end, after a brief review of Latin America’s economic history since the last century, an evaluation is made, on the one hand, of the influence of the growth of Asian developing economies on the terms of trade and Latin America’s export income and, on the other, the changes in the latter continent’s productive structure and trade patterns that may have resulted from the increase of trade with Asia. Finally, some conclusions are offered along with prospects for the future.

    This study examines the history, current status and future prospects for increased coal use in Mexico. Environmental implications of the power-generation capacity expansion plans are examined in general terms. Mexican environmental law and regulations are briefly reviewed along with the new sense of urgency in the cleanup of existing environmental problems and avoidance of new problems as clearly mandated in recent Mexican government policy initiatives. It is expected that new capital facilities will need to incorporate the latest in process and technology to comply with existing environmental regulation. Technology developments which address these issues are identified. What opportunities have new initiatives caused by the recent diversification of Mexico`s energy economy offered US firms? This report looks at the potential future use of coal in the Mexican energy economy, examining this issue with an eye toward identifying markets that might be available to US coal producers and the best way to approach them. Market opportunities are identified by examining new developments in the Mexican economy generally and the energy economy particularly. These developments are examined in light of the current situation and the history which brought Mexico to its present status.

    Full Text Available The existence of cross-border urban areas is a sociological phenomenon that concerns Latin American borders. These settlements are the result of the activation of the flows of capital, goods and people through them and the formation of transborders corridors and regions. Based on a review of several previous theoretical positions, this paper discusses the validity of the conceptual definition of Transborder Urban Complex. Futhermore, it proposes a debate on a number of study variables that account for the nature of the systemic relationships between cities, including demographies, economics, politics, and social relations.

    2015-06-01

    Full Text Available Complexity is a new way of thinking about the world (Snowden Boone, 2007. Some of the attributes of complex phenomena is uncertainty, non-linearity, self-organization, turbulence, and unpredictability. In the situation of dynamically changing external and internal conditions of its functioning, an organization can survive and grow only when it is able to successfully adapt its changeability to the changeability of the environment in which it is operating (Penc, 2002, p.51. The existing and applied systems of decision-making are often inadequate to the new challenges encountered by enterprises.

  3. Security Inequalities in North America: Reassessing Regional Security Complex Theory

    Directory of Open Access Journals (Sweden)

    Richard Kilroy

    2017-12-01

    Full Text Available This article re-evaluates earlier work done by the authors on Regional Security Complex Theory (RSCT in North America, using sectoral analysis initially developed by Buzan and Waever, but also adding the variables of institutions, identity, and interests. These variables are assessed qualitatively in the contemporary context on how they currently impress upon the process of securitization within sectoral relations between Canada, Mexico, and the United States. The article reviews the movement from bilateral security relations between these states to the development of a trilateral response to regional security challenges post- 9/11. It further addresses the present period and what appears to be a security process derailed by recent political changes and security inequalities, heightened by the election of Donald Trump in 2016. The article argues that while these three states initially evinced a convergence of regional security interests after 9/11, which did create new institutional responses, under the current conditions, divergence in political interests and security inequalities have reduced the explanatory power of RSCT in North America. Relations between states in North American are becoming less characterized by the role of institutions and interests and more by identity politics in the region.

  4. An Introduction to Forest Governance, People and REDD+ in Latin America: Obstacles and Opportunities

    Directory of Open Access Journals (Sweden)

    Anne M. Larson

    2011-01-01

    Full Text Available REDD+ is a potentially significant financial mechanism for shifting the incentives from deforestation and land use change to forest conservation and sustainability. Even though REDD+ is not primarily a governance reform, it will affect or be affected by forest governance, it can improve forest governance or be undermined by its failures and, therefore, it depends on good forest governance if it is to be efficient, effective and equitable. This article provides an overview of key issues in forest governance in Latin America and discusses the risk and opportunities for REDD+. Though progress has been made in some areas, there is still much to be done, and REDD+ could reinforce or be undermined by problematic governance tendencies that affect its effectiveness, ability to decrease carbon emissions, and/or its legitimacy. The article recommends priority investments in institutional capacity, inter-institutional negotiation mechanisms, citizen participation and safeguards for forest-based populations.

    2016-02-01

    This study examined Latin American evaluation needs regarding the development of a collaborative mental health care (CMHC) evaluation framework as seen by local key health-care leaders and professionals. Potential implementation challenges and opportunities were also identified. This multisite research study used an embedded mixed methods approach in three public health networks in Mexico, Nicaragua and Chile. Local stakeholders participated: decision-makers in key informant interviews, front-line clinicians in focus groups and other stakeholders through a survey. The analysis was conducted within site and then across sites. A total of 22 semi-structured interviews, three focus groups and 27 questionnaires (52% response rate) were conducted. Participants recognized a strong need to evaluate different areas of CMHC in Latin America, including access, types and quality of services, human resources and outcomes related to mental disorders, including addiction. A priority was to evaluate collaboration within the health system, including the referral system. Issues of feasibility, including the weaknesses of information systems, were also identified. Local stakeholders strongly supported the development of a comprehensive evaluation framework for CMHC in Latin America and cited several dimensions and contextual factors critical for inclusion. Implementation must allow flexibility and adaptation to the local context. © 2015 John Wiley & Sons Ltd.

  6. Applying complex networks to evaluate precipitation patterns over South America

    2016-04-01

    The climate of South America exhibits pronounced differences between the wet- and the dry-season, which are accompanied by specific synoptic events like changes in the location of the South American Low Level Jet (SALLJ) and the establishment of the South American Convergence Zone (SACZ). The onset of these events can be related to the presence of typical large-scale precipitation patterns over South America, as previous studies have shown[1,2]. The application of complex network methods to precipitation data recently received increased scientific attention for the special case of extreme events, as it is possible with such methods to analyze the spatiotemporal correlation structure as well as possible teleconnections of these events[3,4]. In these approaches the correlation between precipitation datasets is calculated by means of Event Synchronization which restricts their applicability to extreme precipitation events. In this work, we propose a method which is able to consider not only extreme precipitation but complete time series. A direct application of standard similarity measures in order to correlate precipitation time series is impossible due to their intricate statistical properties as the large amount of zeros. Therefore, we introduced and evaluated a suitable modification of Pearson's correlation coefficient to construct spatial correlation networks of precipitation. By analyzing the characteristics of spatial correlation networks constructed on the basis of this new measure, we are able to determine coherent areas of similar precipitation patterns, spot teleconnections of correlated areas, and detect central regions for precipitation correlation. By analyzing the change of the network over the year[5], we are also able to determine local and global changes in precipitation correlation patterns. Additionally, global network characteristics as the network connectivity yield indications for beginning and end of wet- and dry season. In order to identify

    2017-01-01

    Full Text Available In opening up the black box of what entrepreneurship education (EE should be about, this study focuses on the exploration of relationships between two constructs: opportunity identification (OI and complex problem-solving (CPS. OI, as a domain-specific capability, is at the core of entrepreneurship research, whereas CPS is a more domain-general skill. On a conceptual level, there are reasons to believe that CPS skills can help individuals to identify potential opportunities in dynamic and nontransparent environments. Therefore, we empirically investigated whether CPS relates to OI among 113 masters students. Data is analyzed using multiple regressions. The results show that CPS predicts the number of concrete ideas that students generate, suggesting that having CPS skills supports the generation of detailed, potential business ideas of good quality. The results of the current study suggest that training CPS, as a more domain-general skill, could be a valuable part of what should be taught in EE.

    Among scholars of social stratification, the most important question about expanding postsecondary education is whether it reduces inequality by creating opportunities for disadvantaged students or whether it increases inequality by concentrating opportunities among those already privileged (Shavit, 2007). This discussion is important because of…

  20. Environmental challenges and opportunities of the evolving North American electricity market : Assessing barriers and opportunities for renewable energy in North America

    International Nuclear Information System (INIS)

    Moomaw, W.R.

    2002-06-01

    A substantial contribution to the electricity supply of North America can be made by renewable energy. Its uses range from transport fuels based on biomass, to space and hot water heating in buildings and industry. Two possible options are distributed forms of renewable energy and central large-scale technology. Significant employment opportunities could be created from the manufacturing, installation and maintenance of renewable technology. In Mexico, the United States and Canada, rural economic development could be enhanced through the use of wind and biomass fuels. Every three years between 1994 and 2001, wind power installations doubled, and a comparable rate was achieved for the period 1996 to 2001 in the case of photovoltaic shipments. North America's share of this accelerating market in renewable energy sources is declining. To rectify the situation, the author indicated that several issues need to be addressed in all three countries and the trading rules in place under the North American Free Trade Agreement (NAFTA) need to be reconciled. Several recommendations were made concerning topics as varied as general policy principles to promote renewable technology, establishment of incentives for renewables, renewable electricity, biomass fuels, economic and social policies, research and development and purchasing. 30 refs

    2015-08-01

    Full Text Available The Central American countries: Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica, and Panama are in transition from a dietary culture based mainly on maize to a wheat-containing diet. Several other changes are occurring, such as a decrease of parasitic and infectious diseases. The environmental changes permit a prediction of an increase of celiac disease and other autoimmune diseases such as type I diabetes and thyroid disease in these genetically heterogeneous countries. At present, celiac disease and gluten-related disorders are considered to be of no relevance at the level of public health in these nations. This review documents the presence of celiac disease in Central America. It draws attention to some of the challenges in planning systematic studies in the region since up until recently celiac disease was unknown. The aim of this review is to disseminate knowledge obtained with preliminary data, to stimulate clinical and basic scientists to study these diseases in Central America and to alert authorities responsible for the planning of education and health, to find possibilities to avoid a rise in these disorders before the epidemics start, as has occurred in the Mediterranean countries.

    The epidemiological transition in Latin America toward older urban dwelling adults has led to the rise in cardiovascular risk factors and an increase in morbidity and mortality rates related to both stroke and myocardial infarction. As a result, there is an immediate need for effective actions resulting in better detection and control of cardiovascular risk factors that will ultimately reduce cardiovascular disease burden. Data from case-control studies have identified the following risk factors associated with stroke: hypertension; smoking; abdominal obesity; diet; physical activity; diabetes; alcohol intake; psychosocial factors; cardiac causes; and dyslipidemia. In addition to its high mortality, patients who survive after a stroke present quite frequently with marked physical and functional disability. Because stroke is the leading cause of death in most Latin American countries and also because it is a clearly preventable cause of death and disability, simple, affordable, and efficient strategies must be urgently implemented in Latin America.

    CONTEXT AND OBJECTIVE Orthopedic research agendas should be considered from a worldwide perspective. Efforts should be planned as the means for obtaining evidence that is valid for health promotion with global outreach. DESIGN AND SETTING Exploratory study conducted at Universidade Federal de São Paulo (Unifesp), São Paulo, Brazil, and McMaster University, Hamilton, Canada. METHODS We identified and analyzed collaborative and multicenter research in Latin America, taking into account American and Canadian efforts as the reference points. We explored aspects of the data available from official sources and used data from traffic accidents as a model for discussing collaborative research in these countries. RESULTS The evaluation showed that the proportion of collaborative and multicenter studies in our setting is small. A brief analysis showed that the death rate due to traffic accidents is very high. Thus, it seems clear to us that initiatives involving collaborative studies are important for defining and better understanding the patterns of injuries resulting from orthopedic trauma and the forms of treatment. Orthopedic research may be an important tool for bringing together orthopedic surgeons, researchers and medical societies for joint action. CONCLUSIONS We have indicated some practical guidelines for initiatives in collaborative research and have proposed some solutions with a summarized plan of action for conducting evidence-based research involving orthopedic trauma.

  8. Comparative assessment of status and opportunities for carbon Dioxide Capture and storage and Radioactive Waste Disposal In North America

    2011-07-22

    Aside from the target storage regions being underground, geologic carbon sequestration (GCS) and radioactive waste disposal (RWD) share little in common in North America. The large volume of carbon dioxide (CO{sub 2}) needed to be sequestered along with its relatively benign health effects present a sharp contrast to the limited volumes and hazardous nature of high-level radioactive waste (RW). There is well-documented capacity in North America for 100 years or more of sequestration of CO{sub 2} from coal-fired power plants. Aside from economics, the challenges of GCS include lack of fully established legal and regulatory framework for ownership of injected CO{sub 2}, the need for an expanded pipeline infrastructure, and public acceptance of the technology. As for RW, the USA had proposed the unsaturated tuffs of Yucca Mountain, Nevada, as the region's first high-level RWD site before removing it from consideration in early 2009. The Canadian RW program is currently evolving with options that range from geologic disposal to both decentralized and centralized permanent storage in surface facilities. Both the USA and Canada have established legal and regulatory frameworks for RWD. The most challenging technical issue for RWD is the need to predict repository performance on extremely long time scales (10{sup 4}-10{sup 6} years). While attitudes toward nuclear power are rapidly changing as fossil-fuel costs soar and changes in climate occur, public perception remains the most serious challenge to opening RW repositories. Because of the many significant differences between RWD and GCS, there is little that can be shared between them from regulatory, legal, transportation, or economic perspectives. As for public perception, there is currently an opportunity to engage the public on the benefits and risks of both GCS and RWD as they learn more about the urgent energy-climate crisis created by greenhouse gas emissions from current fossil-fuel combustion practices.

    2014-01-01

    As stated in Article 6 of Framework Convention on Tobacco Control (FCTC), increasing tobacco prices through higher taxes is one of the most effective interventions to reduce tobacco use and to encourage smokers to quit. The potential for tax increases on tobacco products in Central America is ample. We aim to synthesize the current tobacco taxes situation and highlight research needs to strengthen taxation. In May 2012, a workshop was carried out with representatives from each Central American country to analyze the tobacco tax situation in each country and to identify key research gaps with experts in the field. Tobacco taxes in Central America fall far short of the levels recommended by FCTC. Moreover, the legal framework is complex and creates barriers for higher taxes that require further research and political will. Top research priorities are an in-depth analysis of tobacco tax legislation, impact of tax and price policies, analysis of costs associated to health care of tobacco-related diseases and lost productivity, and the feasibility of approaches to increasing tobacco taxes in certain contexts. An additional area of research is the interrelationship between human rights and tobacco control. Central American countries would benefit from increasing excise taxes on tobacco products. The lack of available data and research to counteract tobacco industry arguments are significant obstacles. Active leadership of civil society in support of the partnership of chronic disease interventions is vital in order to obtain tax increases on tobacco products.

  11. Initial formation of an indigenous crop complex in eastern North America at 3800 B.P.

    2009-04-21

    Although geneticists and archaeologists continue to make progress world-wide in documenting the time and place of the initial domestication of a growing number of plants and animals, far less is known regarding the critically important context of coalescence of various species into distinctive sets or complexes of domesticates in each of the world's 10 or more independent centers of agricultural origin. In this article, the initial emergence of a crop complex is described for one of the best-documented of these independent centers, eastern North America (ENA). Before 4000 B.P. there is no indication of a crop complex in ENA, only isolated evidence for single indigenous domesticate species. By 3800 B.P., however, at least 5 domesticated seed-bearing plants formed a coherent complex in the river valley corridors of ENA. Accelerator mass spectrometer radiocarbon dates and reanalysis of archaeobotanical assemblages from a short occupation of the Riverton Site in Illinois documents the contemporary cultivation at 3800 B.P. of domesticated bottle gourd (Lagenaria siceraria), marshelder (Iva annua var. macrocarpa), sunflower (Helianthus annuus var. macrocarpus), and 2 cultivated varieties of chenopod (Chenopodium berlandieri), as well as the possible cultivation of Cucurbita pepo squash and little barley (Hordeum pusillum). Rather than marking either an abrupt developmental break or a necessary response to population-packing or compressed resource catchments, the coalescence of an initial crop complex in ENA appears to reflect an integrated expansion and enhancement of preexisting hunting and gathering economies that took place within a context of stable long-term adaptation to resource-rich river valley settings.

    Megacities and Large Urban Complexes - WMO Role in Addressing Challenges and Opportunities Deon E. Terblanche and Liisa Jalkanen dterblanche@wmo.int ljalkanen@wmo.int World Meteorological Organization, Geneva, Switzerland The 21st Century could amongst others, become known as the century in which our species has evolved from Homo sapiens to Homo urbanus. By now the urban population has surpassed the rural population and the rate of urbanization will continue at such a pace that by 2050 urban dwellers could outnumber their rural counterpart by more than two to one. Most of this growth in urban population will occur in developing countries and along coastal areas. Urbanization is to a large extent the outcome of humans seeking a better life through improved opportunities presented by high-density communities. Megacities and large urban complexes provide more job opportunities and social structures, better transport and communication links and a relative abundance of physical goods and services when compared to most rural areas. Unfortunately these urban complexes also present numerous social and environmental challenges. Urban areas differ from their surroundings by morphology, population density, and with high concentration of industrial activities, energy consumption and transport. They also pose unique challenges to atmospheric modelling and monitoring and create a multi-disciplinary spectrum of potential threats, including air pollution, which need to be addressed in an integrated way. These areas are also vulnerable to the changing climate and its implications to sea-level and extreme events, air quality and related health impacts. Many urban activities are significantly impacted by weather events that would not be considered to be of high impact in less densely populated areas. For instance, moderate precipitation events can cause flooding and landslides as modified urban catchments generally have higher run-off to rainfall ratios than their more pristine rural

  13. Defining Genetic, Taxonomic, and Geographic Boundaries Among Species of the Psorophora confinnis (Diptera: Culicidae) Complex in North and South America.

    The Psorophora confinnis complex is currently composed of three species--Psorophora confinnis sensu stricto (Lynch Arribalzaga) in South America, Psorophora columbiae (Dyar and Knab) in North America, and Psorophora jamaicensis (Theobald) in the Caribbean. Members of the complex are of considerable importance as vectors of arboviruses, for example, Venezuelan equine encephalitis virus, and are significant biting pests throughout their range. The biological and geographic boundaries of Ps. confinnis and Ps. columbiae are unclear. In fact, the name Ps. columbiae is presently designated as "provisional." In this article, we aim to clarify the taxonomy and geographic distributions of species within the Ps. confinnis complex. A population genetics approach was employed using gene and genotypic frequency data at 26 isozyme loci. The results suggest that the Ps. confinnis complex in North and South America is composed of four species. Ps. confinnis s.s. and Ps. columbiae are distinct species in South and North America, respectively. Populations in Colombia, South America, formally designated as Ps. funiculus (Dyar) and populations in the southwestern United States and western Mexico, formally designated Ps. toltecum (Dyar and Knab), are distinct species. Psorophora toltecum and Psorophora funiculus species names should be resurrected from synonymy. In addition we identified a Ps. columbiae and Ps. toltecum hybrid zone in central Texas in a region described as being one of 13 North American suture zones, being geographical areas in which closely related species occur in sympatry and frequently hybridize. © The Authors 2015.

    The purpose of this work is to show which solutions the South American market is putting forth for the new technological model of the automotive fuel for light duty vehicles. A strong and irreversible trend is underway, which is seeking more environmentally friendly and economically attractive alternatives for the conventional automotive technology, based on the consumption of gasoline and diesel fuel. This trend is evident not only in Latin America, but also in many other countries and regions, and has resulted in a great number of vehicle conversions, so as to operate with vehicular natural gas. Another important way in which this trend has expressed itself is the commercial acceptance and success of the tetra fuel technology vehicles. (author)

    Kingsnakes of the Lampropeltis getula complex range throughout much of temperate and subtropical North America. Studies over the last century have used morphology and color pattern to describe numerous subspecies. More recently, DNA analyses have made invaluable contributions to our understanding of their evolution and taxonomy. We use genetic and ecological methods to test previous hypotheses of distinct evolutionary lineages by examining 66 total snakes and 1) analyzing phylogeographic structure using 2 mtDNA loci and 1 nuclear locus, 2) estimating divergence dates and historical demography among lineages in a Bayesian coalescent framework, and 3) applying ecological niche modeling (ENM). Our molecular data and ENMs illustrate that 3 previously recognized subspecies in the eastern United States comprise well-supported monophyletic lineages that diverged during the Pleistocene. The geographic boundaries of these 3 lineages correspond closely to known biogeographic barriers (Florida peninsula, Appalachian Mountains, and Apalachicola River) previously identified for other plants and animals, indicating shared geographic influences on evolutionary history. We conclude that genetic, ecological, and morphological data support recognition of these 3 lineages as distinct species (Lampropeltis floridana, Lampropeltis getula, and Lampropeltis meansi). © The American Genetic Association 2017.

    Full Text Available Multisectoral actions for health, defined as actions undertaken by non-health sectors to protect the health of the population, are essential in the context of inter-linkages between three dimensions of sustainable development: economic, social, and environmental. These multisectoral actions can address the social and economic factors that influence the health of a population at the local, national, and global levels. This editorial identifies the challenges, opportunities and capacity development for effective multisectoral actions for health in a complex policy environment. The root causes of the challenges lie in poor governance such as entrenched political and administrative corruption, widespread clientelism, lack of citizen voice, weak social capital, lack of trust and lack of respect for human rights. This is further complicated by the lack of government effectiveness caused by poor capacity for strong public financial management and low levels of transparency and accountability which leads to corruption. The absence of or rapid changes in government policies, and low salary in relation to living standards result in migration out of qualified staff. Tobacco, alcohol and sugary drink industries are major risk factors for non-communicable diseases (NCDs and had interfered with health policy through regulatory capture and potential law suits against the government. Opportunities still exist. Some World Health Assembly (WHA and United Nations General Assembly (UNGA resolutions are both considered as external driving forces for intersectoral actions for health. In addition, Thailand National Health Assembly under the National Health Act is another tool providing opportunity to form trust among stakeholders from different sectors.

    Stigma towards mental illness and addictive disorders is a global problem and one of the main obstacles in tackling this issue remains the effective integration of mental health services into primary health care (PHC). In Latin America, information has significantly increased on the existence of stigma; however, little is known about effective interventions to prevent stigma and promote recovery-oriented practices in PHC. The aim of this study is to understand the existing evidence regarding mental health stigma in PHC with a special focus on the Latin American region. A scoping review of the literature related to mental health stigma in PHC was conducted. Two hundred and seventeen articles were evaluated; 74 met inclusion criteria and 14 additional articles were selected from references of search results. Results were subdivided into five different perspectives: users, family members and significant others, health professionals, contextual factors, and potential effective interventions. Only nine studies were based in Latin America, and only one described an intervention to reduce stigma in mental health services, not specifically in PHC. We found an urgent need to develop interventions to understand and reduce stigma in PHC settings, especially in Latin America.

  20. The Rise of Complexity in Flood Forecasting: Opportunities, Challenges and Tradeoffs

    2017-12-01

    Operational flood forecasting is currently undergoing a major transformation. Most national flood forecasting services have relied for decades on lumped, highly calibrated conceptual hydrological models running on local office computing resources, providing deterministic streamflow predictions at gauged river locations that are important to stakeholders and emergency managers. A variety of recent technological advances now make it possible to run complex, high-to-hyper-resolution models for operational hydrologic prediction over large domains, and the US National Weather Service is now attempting to use hyper-resolution models to create new forecast services and products. Yet other `increased-complexity' forecasting strategies also exist that pursue different tradeoffs between model complexity (i.e., spatial resolution, physics) and streamflow forecast system objectives. There is currently a pressing need for a greater understanding in the hydrology community of the opportunities, challenges and tradeoffs associated with these different forecasting approaches, and for a greater participation by the hydrology community in evaluating, guiding and implementing these approaches. Intermediate-resolution forecast systems, for instance, use distributed land surface model (LSM) physics but retain the agility to deploy ensemble methods (including hydrologic data assimilation and hindcast-based post-processing). Fully coupled numerical weather prediction (NWP) systems, another example, use still coarser LSMs to produce ensemble streamflow predictions either at the model scale or after sub-grid scale runoff routing. Based on the direct experience of the authors and colleagues in research and operational forecasting, this presentation describes examples of different streamflow forecast paradigms, from the traditional to the recent hyper-resolution, to illustrate the range of choices facing forecast system developers. We also discuss the degree to which the strengths and

    individuals with tuberous sclerosis complex; however, few data are available regarding practical clinical tools for early identification. In our case series, inclusion of the Capute Scales as a part of routine medical care led to the identification of developmental delays in the first 12 months of life and selection of targeted neurodevelopmental interventions. Development of a risk-based assessment using this approach will be the focus of future studies as it may provide a potential window of opportunity for both research and clinical purposes. In research, it may serve as an objective outcome measure. Clinically, this type of assessment has potential for informing clinical treatment decisions and serving as a prognostic indicator of long-term cognitive and psychiatric outcomes.

    Vaccination Week in the Americas (VWA) is an annual initiative in countries and territories of the Americas every April to highlight the work of national expanded programs on immunization (EPI) and increase access to vaccination services for high-risk population groups. In 2011, as part of VWA, Venezuela targeted children aged less than 6 years in 25 priority border municipalities using social mobilization to increase institution-based vaccination. Implementation of social communication activities was decentralized to the local level. We conducted a survey in one border municipality of Venezuela to evaluate the outcome of VWA 2011 and provide a snapshot of the overall performance of the routine EPI at that level. We conducted a coverage survey, using stratified cluster sampling, in the Venezuelan municipality of Bolivar (bordering Colombia) in August 2011. We collected information for children aged 85%, with a few exceptions. Low levels of VWA awareness among caregivers probably contributed to the limited vaccination of eligible children during the VWA activities in Bolivar in 2011. However, vaccine coverage for most EPI vaccines was high. Additionally, high vaccination card availability and high participation in VWA among those caregivers aware of it in 2011 suggest public trust in the EPI program in the municipality. Health authorities have used survey findings to inform changes to the routine EPI and better VWA implementation in subsequent years.

    Full Text Available This article analyses the opportunities and complexities of the SADC mediation in Zimbabwe’s Global Political Agreement (GPA in facilitating and operationalising theprinciples and values of peace, security, human rights and democracy as set out in Article 4 of the SADC treaty. It attempts to interrogate the extent to which the regional grouping’s mechanisms for enforcing its principles and values have been successful.   The article argues that despite SADC’s noble commitment to promoting the development of democratic institutions and practices, as well as encouraging the observance of universal human rights, peace and security, the resolution of the Zimbabwe crisis shows that, in practice, the operationalisation of SADC protocol principles and values have been a sorry saga of delays, secrecy, purported agreements and nothing concrete coming out of it.  Using the Zimbabwe case study, this article further argues that SADC either lacks appropriate power and authority or is reluctant to hold member states accountable.  This seems so, given that as a regional body, it has allowed itself to be utterly inadequate to the task envisioned by the organ in resolving the Zimbabwe crisis. The paper concludes that the sum of all this has had the effect of exposing SADC and it being perceived as a weak regional organisation.

    Mycobacterium avium complex (MAC) infections are the most frequent systemic infections associated with advanced AIDS. DNA probes for accurate identification of mycobacteria are available but are very expensive in many Latin American settings. Consequently, most Latin American diagnostic laboratories employ inaccurate and outdated tests for mycobacteria identification. Therefore, PCR restriction analysis (PRA) of the hsp65 gene was evaluated for the identification of 163 MAC human isolates originated from Spain and South America. The predominant PRA type in each country was: M. avium type I in Argentina (23/42, 55%) and Brazil (48/72, 67%), M. avium type II in Spain (18/26, 69%) and M. avium type III in Colombia (10/23, 43%). The Colombia frequency is noteworthy, since the PRA type III was quite infrequent in the other three countries. Furthermore, its presence has not been reported outside the Americas. The advantages and disadvantages of PRA in diagnostic mycobacteriology are discussed.

    Lyme borreliosis group spirochaetes are parasitic bacteria transmitted by vector ticks of the genus Ixodes and distributed mainly between 40° and 60° northern latitudes. Since Borrelia burgdorferi sensu stricto (hereinafter, B. burgdorferi) was described in the north-eastern USA during the early 1980s, an increasing diversity has been noted within the species complex. Here, we describe a novel genomic species, Borrelia kurtenbachii sp. nov. (type strain 25015(T) = ATCC BAA-2495(T) =  DSM 26572(T)), that is prevalent in transmission cycles among vector ticks and reservoir hosts in North America. Confirmation of the presence of this species in Europe awaits further investigation.

  10. Opportunities and Challenges in Enhancing Value of Annual Glacier Mass Balance Monitoring Examples from Western North America

    Pelto, M. S.

    2017-12-01

    Alpine glacier mass balance is the most accurate indicator of glacier response to climate and with retreat of alpine glaciers is one of the clearest signals of global climate change. Completion of long term, representative and homogenous mass balance field measurement of mass balance, compiled by WGMS, is a key climate data record. To ensure a monitoring program remains vital and funded local collaboration and connecting the research to local societal impacts is crucial. Working with local partners in collecting and providing the right data is critical whether their interest is in hydropower, irrigation, municipal supply, hazard reduction and/or aquatic ecosystems. The expansion of remote sensing and modeling capability provides both a challenge to continued relevance and an opportunity for field mass balance programs to expand relevance. In modelling studies of both glacier mass balance and glacier runoff transient balance data has equivalent value with annual balance data, for both calibration runs and as an input variable. This increases the utility of mid-season field observations. Remote sensing provides repeat imagery that often identifies the AAR and transient snowline of a glacier. For runoff assessment understanding the specific percent of glacier surface area that is glacier ice, older firn, and retained snowpack from the previous winter at frequent intervals during the melt season is vital since each region has a different melt factor. A denser field observation network combined with this imagery can provide additional point balance values of ablation that complement the mass balance record. Periodic measurement of mass balance at a denser network using GPR, LIDAR, TLS or probing is required to better understand long term point balance locations and is important at end of the melt season not just beginning, and has value mid-season for modelling. Applications of each of utility of field mass balance observations will be illustrated.

    2015-06-01

    Full Text Available Recent molecular studies indicate that the Pyropia lanceolata species complex on the west coast of North America is more speciose than previously thought. Based on extensive rbcL gene sequencing of representative specimens we recognize seven species in the complex, three of which are newly described: Py. montereyensis sp. nov., Py. columbiensis sp. nov., and Py. protolanceolata sp. nov. The new species are all lanceolate, at least when young, and occur in the upper mid to high intertidal zone primarily in winter and early spring. Pyropia montereyensis and Py. columbiensis are sister taxa that are distributed south and north of Cape Mendocino, respectively, and both occur slightly lower on the shore than Py. lanceolata or Py. pseudolanceolata. Pyropia protolanceolata is known thus far only from Morro Rock and the Monterey Peninsula, California; it occurs basally to the other species in the complex in the molecular phylogeny. A fourth newly described species, Pyropia bajacaliforniensis sp. nov., is more closely related to Py. nereocystis than to species in this complex proper. It is a thin species with undulate margins known only from Moss Landing, Monterey Bay, California, and northern Baja California; it also occurs in the high intertidal in spring. Porphyra mumfordii, a high intertidal winter species that has frequently been confused with species in the Py. lanceolata complex, has now been confirmed to occur from Calvert Island, British Columbia, to Pescadero State Park, California.

    Latin America and the Caribbean have not yet developed strong clinical cancer research programmes. In order to improve this situation two international cancer organisations, the Latin American Society of Clinical Oncology (SLACOM) and the European Society of Medical Oncology (ESMO) worked closely with the Peruvian Cooperative Oncology Group (GECOPERU) and organised a clinical cancer research workshop held in Lima, Peru, in October 2015. Many oncologists from different Latin American countries participated in this gathering. The opportunities for and strengths of clinical oncology research in Latin American and Caribbean countries were identified as the widespread use of the Spanish language, the high cancer burden, growing access to information, improving patient education, access to new drugs for research centres, regional networks and human resources. However, there are still many weaknesses and problems including the long timeline for regulatory approval, lack of economic investment, lack of training and lack of personnel participating in clinical research, lack of cancer registries, insufficient technology and insufficient supplies for the diagnosis and treatment of cancer, few cancer specialists, low general levels of education and the negative attitude of government authorities towards clinical research.

    2013-07-01

    Full Text Available This article argues that the South African developmental landscape is currently locked into an overly technical, path dependent paradigm that is unlikely to be capable of embracing the complex challenges identified by the recent National Development Plan. The article explores the internal logic of the existing path dependent, technical condition from the perspective of complexity, in the context of the Department of Science and Technology’s Fifth Grand Challenge and “continuous change”. It is argued that drawing ideas from complexity into future developmental trajectories can add value to the National Development Plan: Vision 2030, but to do so will require dynamic mind-set shifts across multiple developmental scales and interfaces if new approaches to managing development that embraces complexity, rather than denies it, is to emerge.

  15. Occlusal enamel complexity in middle miocene to holocene equids (Equidae: Perissodactyla of North America.

    Directory of Open Access Journals (Sweden)

    Nicholas A Famoso

    Full Text Available Four groups of equids, "Anchitheriinae," Merychippine-grade Equinae, Hipparionini, and Equini, coexisted in the middle Miocene, but only the Equini remains after 16 Myr of evolution and extinction. Each group is distinct in its occlusal enamel pattern. These patterns have been compared qualitatively but rarely quantitatively. The processes influencing the evolution of these occlusal patterns have not been thoroughly investigated with respect to phylogeny, tooth position, and climate through geologic time. We investigated Occlusal Enamel Index, a quantitative method for the analysis of the complexity of occlusal patterns. We used analyses of variance and an analysis of co-variance to test whether equid teeth increase resistive cutting area for food processing during mastication, as expressed in occlusal enamel complexity, in response to increased abrasion in their diet. Results suggest that occlusal enamel complexity was influenced by climate, phylogeny, and tooth position through time. Occlusal enamel complexity in middle Miocene to Modern horses increased as the animals experienced increased tooth abrasion and a cooling climate.

    2006-10-15

    Climate change and biodiversity loss are both major environmental concerns, yet the links between them often go unrecognised. Not only does the science of climate change and biodiversity share similar characteristics, but climate change both affects, and is affected by biodiversity. Diversity confers far greater resilience on natural systems, thus reducing their vulnerability – and the vulnerability of the people that depend upon them – to climate change. Yet climate adaptation and mitigation strategies that are blind to biodiversity can undermine this natural and social resilience. Ignoring the links between biodiversity and climate risks exacerbates the problems associated with climate change and represents a missed opportunity for maximising co-benefits.

  19. Computational Docking of Antibody-Antigen Complexes, Opportunities and Pitfalls Illustrated by Influenza Hemagglutinin

    Directory of Open Access Journals (Sweden)

    Mattia Pedotti

    2011-01-01

    Full Text Available Antibodies play an increasingly important role in both basic research and the pharmaceutical industry. Since their efficiency depends, in ultimate analysis, on their atomic interactions with an antigen, studying such interactions is important to understand how they function and, in the long run, to design new molecules with desired properties. Computational docking, the process of predicting the conformation of a complex from its separated components, is emerging as a fast and affordable technique for the structural characterization of antibody-antigen complexes. In this manuscript, we first describe the different computational strategies for the modeling of antibodies and docking of their complexes, and then predict the binding of two antibodies to the stalk region of influenza hemagglutinin, an important pharmaceutical target. The purpose is two-fold: on a general note, we want to illustrate the advantages and pitfalls of computational docking with a practical example, using different approaches and comparing the results to known experimental structures. On a more specific note, we want to assess if docking can be successful in characterizing the binding to the same influenza epitope of other antibodies with unknown structure, which has practical relevance for pharmaceutical and biological research. The paper clearly shows that some of the computational docking predictions can be very accurate, but the algorithm often fails to discriminate them from inaccurate solutions. It is of paramount importance, therefore, to use rapidly obtained experimental data to validate the computational results.

    2017-08-01

    The goal of this review article is to provide a conceptual based summary of how heritability estimates for complex traits such as obesity are determined and to explore the future directions of research in the heritability field. The target audience are researchers who use heritability data rather than those conducting heritability studies. The article provides an introduction to key concepts critical to understanding heritability studies including: i) definitions of heritability: broad sense versus narrow sense heritability; ii) how data for heritability studies are collected: twin, adoption, family and population-based studies; and iii) analytical techniques: path analysis, structural equations and mixed or regressive models of complex segregation analysis. For each section, a discussion of how the different definitions and methodologies influence heritability estimates is provided. The general limitations of heritability studies are discussed including the issue of "missing heritability" in which heritability estimates are significantly higher than the variance explained by known genetic variants. Potential causes of missing heritability include restriction of many genetic association studies to single nucleotide polymorphisms, gene by gene interactions, epigenetics, and gene by environment interactions. Innovative strategies of accounting for missing heritability including modeling techniques and improved software are discussed.

    This paper provides an overview of racial variations in health and shows that differences in socioeconomic status (SES) across racial groups are a major contributor to racial disparities in health. However, race reflects multiple dimensions of social inequality and individual and household indicators of SES capture relevant but limited aspects of this phenomenon. Research is needed that will comprehensively characterize the critical pathogenic features of social environments and identify how they combine with each other to affect health over the life course. Migration history and status are also important predictors of health and research is needed that will enhance understanding of the complex ways in which race, SES, and immigrant status combine to affect health. Fully capturing the role of race in health also requires rigorous examination of the conditions under which medical care and genetic factors can contribute to racial and SES differences in health. The paper identifies research priorities in all of these areas.

Intestinal disbiosis disturbs homeostasis, leads to significant disorders in function of other organs and systems. Thus the correction of intestinal disbacteriosis is an actual problem of clinical pediatrics, and different specialists meet this problem. One of common causes of intestinal disbiosis is antibacterial treatment. Almost all antimicrobial drugs influence gastrointestinal tract and their administration lead to dyspepsia and antibiotic-associated diarrhea. Normalization of intestinal microflora is significant stage of complex treatment of these pathological states in children. The choice of probiotic drug should be well grounded.

    Conspectus The development of next-generation lithium-based rechargeable batteries with high energy density, low cost, and improved safety is a great challenge with profound technological significance for portable electronics, electric vehicles, and grid-scale energy storage. Specifically, advanced lithium battery chemistries call for a paradigm shift to electrodes with high Li to host ratio based on a conversion or alloying mechanism, where the increased capacity is often accompanied by drastic volumetric changes, significant bond breaking, limited electronic/ionic conductivity, and unstable electrode/electrolyte interphase. Fortunately, the rapid progress of nanotechnology over the past decade has been offering battery researchers effective means to tackle some of the most pressing issues for next-generation battery chemistries. The major applications of nanotechnology in batteries can be summarized as follows: First, by reduction of the dimensions of the electrode materials, the cracking threshold of the material upon lithiation can be overcome, at the same time facilitating electron/ion transport within the electrode. Second, nanotechnology also provides powerful methods to generate various surface-coating and functionalization layers on electrode materials, protecting them from side reactions in the battery environment. Finally, nanotechnology gives people the flexibility to engineer each and every single component within a battery (separator, current collector, etc.), bringing novel functions to batteries that are unachievable by conventional methods. Thus, this Account aims to highlight the crucial role of nanotechnology in advanced battery systems. Because of the limited space, we will mainly assess representative examples of rational nanomaterials design with complexity for silicon and lithium metal anodes, which have shown great promise in constraining their large volume changes and the repeated solid–electrolyte interphase formation during cycling

    industry. Therefore in this region there is an urgent need to establish prevention and treatment strategies capable to reduce incidence and prevalence of tobacco smoking in the population and as a consequence modify the health effects of tobacco consumption. Treating nicotine addiction requires intervention strategies really effective to reduce the number of current smokers as well as giving them tools to avoid relapse and maintain abstinence. Currently poor and vulnerable groups, which represent 44% of the total population in Latin America, are the most susceptible to suffer the health consequences of smoking since they show the highest prevalence rates and have little or no access to health services. The Framework Convention on Tobacco Control (FCTC and MPOWER, both strategies proposed by the World Health Organization against tobacco, define clear goals to achieve their purposes, nevertheless they are limited by the economic and human resources assigned by each country. The scientific community involved in the fight against tobacco must think about new ways to place this issue in the political agenda so there will be more opportunities to increase the resources and therefore to reduce tobacco consumption in all the groups of the population. In the fight against tobacco, this is the right time to consider primarily issues related to equity and social justice.

    Directory of Open Access Journals (Sweden)

    Manuel Heitor

    2014-09-01

    Full Text Available In view of the current global context, which challenges are facing science- and technology-based developments and cooperation in a way to contribute for policies that stimulate localized learning, innovation and endogenous development in Latin America? This broad question has motivated the work behind the Special Issue introduced by this paper, which considers the development of case studies in selected Latin America regions. The analysis lead us to argue that value-based networks have the potential to make both public policies and markets more effective, promoting learning trajectories for the inclusive development of regions. But they require effective public investments to keep attracting and qualifying human resources, together with long-term developments towards technical industries and export capacity for emerging markets worldwide. Our analysis argues about the unique potential for further developing Latin America through strategic international, knowledge-based ventures, exploring the emerging role the internationalization of universities and scientific institutions may play at a global level. Above all, they require the systematic observation of science and technical change in international comparison, as well as a relational infrastructure for collective action, at an international level, in a context much influenced by a dynamic of change and a necessary balance between the creation and diffusion of knowledge towards the endogenous development of all parts involved. The role of Latin America Universities and science policies based on international cooperation are considered to be particularly important in this process.

  7. Unraveling the complex local-scale flows influencing ozone patterns in the southern Great Lakes of North America

    Directory of Open Access Journals (Sweden)

    I. Levy

    2010-11-01

    Full Text Available This study examines the complexity of various processes influencing summertime ozone levels in the southern Great Lakes region of North America. Results from the Border Air Quality and Meteorology (BAQS-Met field campaign in the summer of 2007 are examined with respect to land-lake differences and local meteorology using a large array of ground-based measurements, aircraft data, and simulation results from a high resolution (2.5 km regional air-quality model, AURAMS.

    Analyses of average ozone mixing ratio from the entire BAQS-Met intensive campaign period support previous findings that ozone levels are higher over the southern Great Lakes than over the adjacent land. However, there is great heterogeneity in the spatial distribution of surface ozone over the lakes, particularly over Lake Erie during the day, with higher levels located over the southwestern end of the lake. Model results suggest that some of these increased ozone levels are due to local emission sources in large nearby urban centers. While an ozone reservoir layer is predicted by the AURAMS model over Lake Erie at night, the land-lake differences in ozone mixing ratios are most pronounced during the night in a shallow inversion layer of about 200 m above the surface. After sunrise, these differences have a limited effect on the total mass of ozone over the lakes and land during the day, though they do cause elevated ozone levels in the lake-breeze air in some locations.

    The model also predicts a mean vertical circulation during the day with an updraft over Detroit-Windsor and downdraft over Lake St. Clair, which transports ozone up to 1500 m above ground and results in high ozone over the lake.

    Oscillations in ground-level ozone mixing ratios were observed on several nights and at several ground monitoring sites, with amplitudes of up to 40 ppbv and time periods of 15–40 min. Several possible mechanisms for these oscillations are discussed, but a

    North America produces and uses over 50 per cent of the electricity in the industrialized world. Regulatory trends in Mexico, the United States and Canada converge toward the opening up of electricity markets, while regional trade of electricity across national borders is being encouraged. Fundamental questions remain concerning the effects on the natural air-water-and-land environment in all three countries and the manner in which this trade occurs. Public health is also a factor to be considered. Some government intervention is required, was the general consensus arrived at at the symposium organized by the Commission for Environmental Cooperation of North America (CEC). This intervention should probably take the form of emission standards, transparent regulatory hearings and efforts to render the rules in the three countries more compatible. Demand growth and the incorporation of pollution controls will require some private investment. The author indicated that the symposium participants recognized that the reconciliation of an efficient continental electricity market with environmental goals will come with improving the efficiency with which North Americans use energy. refs., 1 tab., 1 fig

    Full Text Available The bacterium Xylella fastidiosa is a plant pathogen with a history of economically damaging introductions of subspecies to regions where its other subspecies are native. Genetic evidence is presented demonstrating the introduction of two new taxa into Central America and their introgression into the native subspecies, X. fastidiosa subsp. fastidiosa. The data are from 10 genetic outliers detected by multilocus sequence typing (MLST of isolates from Costa Rica. Six (five from oleander, one from coffee defined a new sequence type (ST53 that carried alleles at six of the eight loci sequenced (five of the seven MLST loci diagnostic of the South American subspecies Xylella fastidiosa subsp. pauca which causes two economically damaging plant diseases, citrus variegated chlorosis and coffee leaf scorch. The two remaining loci of ST53 carried alleles from what appears to be a new South American form of X. fastidiosa. Four isolates, classified as X. fastidiosa subsp. fastidiosa, showed a low level of introgression of non-native DNA. One grapevine isolate showed introgression of an allele from X. fastidiosa subsp. pauca while the other three (from citrus and coffee showed introgression of an allele with similar ancestry to the alleles of unknown origin in ST53. The presence of X. fastidiosa subsp. pauca in Central America is troubling given its disease potential, and establishes another route for the introduction of this economically damaging subspecies into the US or elsewhere, a threat potentially compounded by the presence of a previously unknown form of X. fastidiosa.

    Chen, Moon S.

    1995-01-01

    PURPOSE. This paper is based on the author's keynote address given at the Seventh International Conference on the Health Problems of Chinese in North America. METHODS. The author/speaker reviewed the literature related to Chinese American health problems within the context of the broader demographic and aggregated health data reported on Asian Americans and Pacific Islanders. FINDINGS. In addition to background demographic statistics provided on Chinese Americans, the author/speaker focused on two categories of diseases: (1) communicable diseases; and (2) chronic diseases because of the greater availability of data on these categories. Communicable diseases from which Chinese Americans appear to suffer disproportionally are tuberculosis and hepatitis B. Infection with the hepatitis B virus also makes Chinese Americans much more susceptible to chronic liver diseases including cancer. Chinese also suffer disproportionally more from nasopharyngeal cancer; because of higher than average adult male smoking rates, these men can be expected to suffer disproportionally from a future epidemic of lung cancer cases. Unhealthy acculturation patterns in food consumption point towards changing profiles of cardiovascular morbidity and mortality as well as higher rates of dietary related cancers. OBSERVATIONS. Rather than conclusions, observations of the current health status of Chinese Americans were offered. Four measures that organizations such as the Chinese medical societies and Chinese American health professionals can pursue to advance the health status of Chinese Americans, particularly in the area of heaslth policy, are: (1) voting; (2) collecting data on health status; (3) writing for professional journals; and (4) being active in policy development.

  17. Three-Level Mixed-Effects Logistic Regression Analysis Reveals Complex Epidemiology of Swine Rotaviruses in Diagnostic Samples from North America.

    Full Text Available Rotaviruses (RV are important causes of diarrhea in animals, especially in domestic animals. Of the 9 RV species, rotavirus A, B, and C (RVA, RVB, and RVC, respectively had been established as important causes of diarrhea in pigs. The Minnesota Veterinary Diagnostic Laboratory receives swine stool samples from North America to determine the etiologic agents of disease. Between November 2009 and October 2011, 7,508 samples from pigs with diarrhea were submitted to determine if enteric pathogens, including RV, were present in the samples. All samples were tested for RVA, RVB, and RVC by real time RT-PCR. The majority of the samples (82% were positive for RVA, RVB, and/or RVC. To better understand the risk factors associated with RV infections in swine diagnostic samples, three-level mixed-effects logistic regression models (3L-MLMs were used to estimate associations among RV species, age, and geographical variability within the major swine production regions in North America. The conditional odds ratios (cORs for RVA and RVB detection were lower for 1-3 day old pigs when compared to any other age group. However, the cOR of RVC detection in 1-3 day old pigs was significantly higher (p 55 day old age groups. Furthermore, pigs in the 21-55 day old age group had statistically higher cORs of RV co-detection compared to 1-3 day old pigs (p < 0.001. The 3L-MLMs indicated that RV status was more similar within states than among states or within each region. Our results indicated that 3L-MLMs are a powerful and adaptable tool to handle and analyze large-hierarchical datasets. In addition, our results indicated that, overall, swine RV epidemiology is complex, and RV species are associated with different age groups and vary by regions in North America.

    P. aurelia is currently defined as a complex of 15 sibling species including 14 species designated by Sonneborn (1975) and one, P. sonneborni, by Aufderheide et al. (1983). The latter was known from only one stand (Texas, USA). The main reason for the present study was a new stand of Paramecium in Cyprus, with strains recognized as P. sonneborni based on the results of strain crosses, cytological slides, and molecular analyses of three loci (ITS1-5.8S-ITS2-5'LSU rDNA, COI, CytB). The new stand of P. sonneborni in Europe shows that the species, previously considered endemic, may have a wider range. This demonstrates the impact of under-sampling on the knowledge of the biogeography of microbial eukaryotes. Phylogenetic trees based on all the studied fragments revealed that P. sonneborni forms a separate cluster that is closer to P. jenningsi and P. schewiakoffi than to the other members of the P. aurelia complex.

    Precipitation in the complex terrain of the tropical Andes of South America can be strongly reduced during El Niño events, with impacts on numerous societally-relevant services, including hydropower generation, the main electricity source in Colombia. Simulating rainfall patterns and behavior in such areas of complex terrain has remained a challenge for regional climate models. Current data products such as ERA-Interim and other reanalysis and modelling products generally fail to correctly represent processes at scales that are relevant for these processes. Here we assess the added value to ERA-Interim by dynamical downscaling using the WRF regional climate model, including a comparison of different cumulus parameterization schemes. We found that WRF improves the representation of precipitation during the dry season of El Niño (DJF) events using a 1996-2014 observation period. Further, we use these improved capability to simulate an extreme deforestation scenario under El Niño conditions for an area in the central Andes of Colombia, where a big proportion of the country's hydropower is generated. Our results suggest that forests dampen the effects of El Niño on precipitation. In synthesis, our results illustrate the utility of regional modelling to improve data sources, as well as their potential for predicting the local-to-regional effects of global-change-type processes in regions with limited data availability.

  20. Point prevalence and incidence of Mycobacterium tuberculosis complex in captive elephants in the United States of America.

    Captive elephants infected with tuberculosis are implicated as an occupational source of zoonotic tuberculosis. However, accurate estimates of prevalence and incidence of elephant tuberculosis from well-defined captive populations are lacking in the literature. Studies published in recent years contain a wide range of prevalence estimates calculated from summary data. Incidence estimates of elephant tuberculosis in captive elephants are not available. This study estimated the annual point prevalence, annual incidence, cumulative incidence, and incidence density of tuberculosis in captive elephants within the USA during the past 52 years. We combined existing elephant census records from captive elephants in the USA with tuberculosis culture results obtained from trunk washes or at necropsy. This data set included 15 years where each elephant was screened annually. Between 1960 and 1996, the annual point prevalence of tuberculosis complex mycobacteria for both species was 0. From 1997 through 2011, the median point prevalence within the Asian elephant population was 5.1%, with a range from 0.3% to 6.7%. The incidence density was 9.7 cases/1000 elephant years (95% CI: 7.0-13.4). In contrast, the annual point prevalence during the same time period within the African elephant population remained 0 and the incidence density was 1.5 cases/1000 elephant years (95% CI: 0.7-4.0). The apparent increase in new cases noted after 1996 resulted from a combination of both index cases and the initiation of mandatory annual tuberculosis screening in 1997 for all the elephants. This study found lower annual point prevalence estimates than previously reported in the literature. These discrepancies in prevalence estimates are primarily due to differences in terminology and calculation methods. Using the same intensive testing regime, the incidence of tuberculosis differed significantly between Asian and African elephants. Accurate and species specific knowledge of prevalence and

    The circular Bokan Mountain complex (BMC) on southern Prince of Wales Island, southernmost Alaska, is a Jurassic peralkaline granitic intrusion about 3 km in diameter that crosscuts igneous and metasedimentary rocks of the Alexander terrane. The BMC hosts significant rare metal (rare earth elements, Y, U, Th, Zr, and Nb) mineralization related to the last stage of BMC emplacement. U–Pb (zircon) and 40Ar/39Ar (amphibole and whole-rock) geochronology indicates the following sequence of intrusive activity: (i) a Paleozoic basement composed mainly of 469 ± 4 Ma granitic rocks; (ii) intrusion of the BMC at 177 ± 1 Ma followed by rapid cooling through ca. 550 °C at 176 ± 1 Ma that was synchronous with mineralization associated with vertical, WNW-trending pegmatites, felsic dikes, and aegirine–fluorite veins and late-stage, sinistral shear deformation; and (iii) intrusion of crosscutting lamprophyre dikes at >150 Ma and again at ca. 105 Ma. The peralkaline nature of the BMC and the WNW trend of associated dikes suggest intrusion during NE–SW rifting that was followed by NE–SW shortening during the waning stages of BMC emplacement. The 177 Ma BMC was synchronous with other magmatic centres in the Alexander terrane, such as (1) the Dora Bay peralkaline stock and (2) the bimodal Moffatt volcanic suite located ∼30 km north and ∼100 km SE of the BMC, respectively. This regional magmatism is interpreted to represent a regional extensional event that precedes deposition of the Late Jurassic – Cretaceous Gravina sequence that oversteps the Wrangellia and Alexander exotic accreted terranes and the Taku and Yukon–Tanana pericratonic terranes of the Canadian–Alaskan Cordillera.

    Dengue is a systemic arthropod-borne viral disease of major global public health importance. At least 2.5 billion people who live in areas of the world where dengue occurs are at risk of developing dengue fever (DF) and its severe complications, dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). Repeated reemergences of dengue in sudden explosive epidemics often cause public alarm and seriously stress healthcare systems. The control of dengue is further challenged by the lack of ...

  3. Rethinking school-based health centers as complex adaptive systems: maximizing opportunities for the prevention of teen pregnancy and sexually transmitted infections.

    This article examines school-based health centers (SBHCs) as complex adaptive systems, the current gaps that exist in contraceptive access, and the potential to maximize this community resource in teen pregnancy and sexually transmitted infection (STI) prevention efforts. Adolescent pregnancy is a major public health challenge for the United States. Existing community resources need to be considered for their potential to impact teen pregnancy and STI prevention efforts. SBHCs are one such community resource to be leveraged in these efforts. They offer adolescent-friendly primary care services and are responsive to the diverse needs of the adolescents utilizing them. However, current restrictions on contraceptive availability limit the ability of SBHCs to maximize opportunities for comprehensive reproductive care and create missed opportunities for pregnancy and STI prevention. A clinical case explores the current models of health care services related to contraceptive care provided in SBHCs and the ability to meet or miss the needs of an adolescent seeking reproductive care in a SBHC.

    Carbon stocks and fluxes in tropical forests remain large sources of uncertainty in the global carbon budget. Airborne lidar remote sensing is a powerful tool for estimating aboveground biomass, provided that lidar measurements penetrate dense forest vegetation to generate accurate estimates of surface topography and canopy heights. Tropical forest areas with complex topography present a challenge for lidar remote sensing. We compared digital terrain models (DTM) derived from airborne lidar data from a mountainous region of the Atlantic Forest in Brazil to 35 ground control points measured with survey grade GNSS receivers. The terrain model generated from full-density (~20 returns m -2 ) data was highly accurate (mean signed error of 0.19 ± 0.97 m), while those derived from reduced-density datasets (8 m -2 , 4 m -2 , 2 m -2 and 1 m -2 ) were increasingly less accurate. Canopy heights calculated from reduced-density lidar data declined as data density decreased due to the inability to accurately model the terrain surface. For lidar return densities below 4 m -2 , the bias in height estimates translated into errors of 80-125 Mg ha -1 in predicted aboveground biomass. Given the growing emphasis on the use of airborne lidar for forest management, carbon monitoring, and conservation efforts, the results of this study highlight the importance of careful survey planning and consistent sampling for accurate quantification of aboveground biomass stocks and dynamics. Approaches that rely primarily on canopy height to estimate aboveground biomass are sensitive to DTM errors from variability in lidar sampling density.

    2016-12-01

    Xylella fastidiosa, a xylem-limited bacterium transmitted by xylem-fluid-feeding Hemiptera insects, causes economic losses of both woody and herbaceous plant species. A Xyl. fastidiosa subsp. pauca strain, namely CoDiRO, was recently found to be associated with the 'olive quick decline syndrome' in southern Italy (i.e. Apulia region). Recently, some Xyl. fastidiosa strains intercepted in France from Coffea spp. plant cuttings imported from Central and South America were characterized. The introduction of infected plant material from Central America in Apulia was also postulated even though an ad hoc study to confirm this hypothesis is lacking. In the present study, we assessed the complete and draft genome of 27 Xyl. fastidiosa strains. Through a genome-wide approach, we confirmed the occurrence of three subspecies within Xyl. fastidiosa, namely fastidiosa, multiplex and pauca, and demonstrated the occurrence of a genetic clonal complex of four Xyl. fastidiosa strains belonging to subspecies pauca which evolved in Central America. The CoDiRO strain displayed 13 SNPs when compared with a strain isolated in Costa Rica from Coffea sp. and 32 SNPs when compared with two strains obtained from Nerium oleander in Costa Rica. These results support the close relationships of the two strains. The four strains in the clonal complex contain prophage-like genes in their genomes. This study strongly supports the possibility of the introduction of Xyl. fastidiosa in southern Italy via coffee plants grown in Central America. The data also stress how the current global circulation of agricultural commodities potentially threatens the agrosystems worldwide.

    Entrepreneurship is about transforming novel ideas into future business, but it requires an entrepreneurial opportunity to be exploited via an effective strategic and organizational design. While the entrepreneurship literature says much about how to implement and organize new opportunities...... in a market setting (the back-end of entrepreneurial processes), it pays less attention to how entrepreneurs purposely design opportunities (the front-end of entrepreneurial processes). Drawing on methods and processes from the creative design literature, the paper introduces a framework of “opportunity...... design”. The framework explains how opportunities intentionally and pro-actively can be designed from methods and processes of moving-in and moving-out. An illustrative case of opportunity design within the area of sustainable energy and electric cars is presented to link the theoretical discussion...

    Norcen Energy Resources Limited's pursuit of international oil and gas opportunities since the late 1980s were outlined. By 1994 Norcen had exploration and production concessions in 12 countries stretching from Algeria, Russia, Argentina, Indonesia to offshore Australia. The company had seen its share of risks, opportunities and rewards. Since 1994 international efforts of the Company have been focused on lower risk opportunities with exploration upside in defined core areas of South America, particularly in Venezuela, a country with conventional, heavy and ultra-heavy oil resources exceeding that of Saudi Arabia. These, and other similar foreign investments in the formerly closed national oil industries of South America have been greatly facilitated by the political liberalization, economic reforms and stabilization that have taken place there over the past ten years. The story of Norcen's successful bidding on the Oritupano-Leona production block in 1993 and Delta Centro exploration block in 1996 was the subject of this presentation

    Opportunities for expanding the propane market in North America are discussed. The goal of change should be to enhance client satisfaction and loyalty. The current customer base is largely comprised of pick-up trucks, vans and buses in commercial fleet service, police and similar fleet service and privately owned vehicles. Opportunities for the expansion of propane exist due to: vehicles being kept and lasting longer, allowing a longer pay-back time; exhaust emission standards becoming more stringent; the possible introduction of emission standards for substances currently not controlled; and properly combusted CO 2 emissions that are at least 12% lower than gasoline. The continuing development of engine fuel management systems, application of extensive road/highway experience, matching supply and refuelling infrastructure to consumer demands, application in air quality non-attainment areas, and original equipment manufacturer, government and industry cooperation are discussed. 8 figs

    As government increasingly recognizes its own obligations to support and provide family planning as a health and social measure, serious questions are raised as to the proper role for Planned Parenthood World Federation as a private organization. Federal programs both at home and abroad tend to make private fundraising more difficult, whatever the role of this organization may be. Contrary to common impression, experience thus far indicates that the existence of governmental programs does not decrease demands on Planned Parenthood as a private agency. A wide gap also exists between public acceptance, which has been realized, and public conviction, which still has not been accepted. Only those who feel distress at the vision of an all-encompassing megalopolis, only those with concern for the qualify of life in the crowd, and only those who see finite limits of resources recognize that the US must someday plan a halt to population growth. As the gap between the developed and the underdeveloped world widens, economists point out that the US, with less than 6% of the world's population, already consumes some 50% of the world's available raw materials. Business and government leaders are beginning to understand the rate at which an industrial and affluent society consumes the world's substance and threatens the environment. If the assumption is correct that the population explosion constitutes a major threat to life on earth, then America's own attitudes and actions at home, as well as abroad and in the developing countries, are vital. In the next few years Planned Parenthood faces the task of converting the tide of public acceptance into one of conviction and effective action on a giant scale both at home and abroad. In its effort, Planned Parenthood has continued to expand its own service functions. It now has 157 local affiliates with an additional 30 in the organizational stage. In 1967 Planned Parenthood affiliates operated 470 family planning centers, 71 more than

    The panel discussing market opportunities for municipal electric companies was moderated by Markham Mayor Don Cousens. He expressed himself in favour of deregulation and was optimistic about the benefits it will bring to municipal electric utilities and their customers. Barry Chuddy, General Manager of Business Development for TransAlta Energy discussed the advantages of recent cogeneration and district energy for municipal utilities in Ontario and Quebec, and expressed his support for incentive-based regulation based on a level playing field, competitive generation, and a reasonable charge for stranded assets. Toronto City Councillor Dan Leckie described cogeneration and district energy as a tremendous opportunity to reduce the cost of doing business in the city core through local job creation and by keeping money in the local economy. Karl Wahl, General Manager of Hydro Mississauga expressed optimism that the government will move expeditiously toward competition, choice and lower-cost supply. David McGarry, President of Elecsar Engineering of Sarnia spoke about the significant job creating potential that deregulation will bring to the electrical industry. He cited several examples from Ontario and British Columbia

    2016-12-01

    It is well known that sexual selection can target reproductive traits during successive pre- and post-mating episodes of selection. A key focus of recent studies has been to understand and quantify how these episodes of sexual selection interact to determine overall variance in reproductive success. In this article, we review empirical developments in this field but also highlight the considerable variability in patterns of pre- and post-mating sexual selection, attributable to variation in patterns of resource acquisition and allocation, ecological and social factors, genotype-by-environment interaction and possible methodological factors that might obscure such patterns. Our aim is to highlight how (co)variances in pre- and post-mating sexually selected traits can be sensitive to changes in a range of ecological and environmental variables. We argue that failure to capture this variation when quantifying the opportunity for sexual selection may lead to erroneous conclusions about the strength, direction or form of sexual selection operating on pre- and post-mating traits. Overall, we advocate for approaches that combine measures of pre- and post-mating selection across contrasting environmental or ecological gradients to better understand the dynamics of sexual selection in polyandrous species. We also discuss some directions for future research in this area. © 2016 European Society For Evolutionary Biology. Journal of Evolutionary Biology © 2016 European Society For Evolutionary Biology.

    Full Text Available Se realizó un estudio acerca de los factores que influyen en que el desarrollo tecnológico de la cirugía refractiva en América Latina y el Caribe no sea accesible a todos, a pesar de la alta cifra de pacientes con limitación visual por ametropías no corregidas. Esto provoca discriminación o exclusión social. Se hizo una revisión documental en Internet sobre los avances tecnológicos en esta subespecialidad y sus consecuencias, con el objetivo de analizar la posible causa de esta problemática y conocer qué pueden hacer o ya están haciendo los países de nuestro continente -incluso en Cuba- para combatirlo y mejorar así la calidad de vida de la población latinoamericana. Podemos concluir que tiene una génesis social, y que se destacan los factores que la han agravado como son la privatización de la salud, violaciones éticas y de la relación médico-paciente, gobiernos que no dan prioridad a la salud y políticas sanitarias que no benefician a la población necesitada, entre otros. Es necesario que los países latinoamericanos consideren la discapacidad visual como una prioridad, destinen recursos para ello y apliquen tecnologías apropiadas en correspondencia con sus posibilidades tecnológicas nacionales, contexto social, económico, político y cultural.

    This article reviews the literature on migration and HIV/AIDS in Mexico and Central America, including Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, and Panama. Most migrants travel to the US through Mexico. US-Mexico trade agreements created opportunities for increased risk of HIV transmission. The research literature focuses on Mexico. Most countries, with the exception of Belize and Costa Rica, are sending countries. Human rights of migrants are violated in transit and at destination. Migration policies determine migration processes. The Mexican-born population in the US is about 3% of US population and 8% of Mexico's population. About 22% arrived during 1992-97, and about 500,000 are naturalized US citizens. An additional 11 million have a Mexican ethnic background. Mexican migrants are usually economically active men who had jobs before leaving and were urban people who settled in California, Texas, Illinois, and Arizona. Most Mexican migrants enter illegally. Many return to Mexico. The main paths of HIV transmission are homosexual, heterosexual, and IV-drug-injecting persons. Latino migrants frequently use prostitutes, adopt new sexual practices including anal penetration among men, greater diversity of sexual partners, and use of injectable drugs.

    Despite research on the health and safety of mobile and migrant populations in the formal and informal sectors globally, limited information is available regarding the working conditions, health, and safety of sex workers who engage in short-term mobility and migration. The objective of this study was to longitudinally examine work environment, health, and safety experiences linked to short-term mobility/migration (i.e., worked or lived in another city, province, or country) among sex workers in Vancouver, Canada, over a 2.5-year study period (2010-2012). We examined longitudinal correlates of short-term mobility/migration (i.e., worked or lived in another city, province, or country over the 3-year follow-up period) among 646 street and off-street sex workers in a longitudinal community-based study (AESHA). Of 646 sex workers, 10.84 % (n = 70) worked or lived in another city, province, or country during the study. In a multivariate generalized estimating equations (GEE) model, short-term mobility/migration was independently correlated with older age (adjusted odds ratio (AOR) 0.95, 95 % confidence interval (CI) 0.92-0.98), soliciting clients in indoor (in-call) establishments (AOR 2.25, 95 % CI 1.27-3.96), intimate partner condom refusal (AOR 3.00, 1.02-8.84), and barriers to health care (AOR 1.77, 95 % CI 1.08-2.89). In a second multivariate GEE model, short-term mobility for sex work (i.e., worked in another city, province, or country) was correlated with client physical/sexual violence (AOR 1.92, 95 % CI 1.02-3.61). In this study, mobile/migrant sex workers were more likely to be younger, work in indoor sex work establishments, and earn higher income, suggesting that short-term mobility for sex work and migration increase social and economic opportunities. However, mobility and migration also correlated with reduced control over sexual negotiation with intimate partners and reduced health care access, and mobility for sex work was associated with

    2018-03-26

    Elia Kazan's 1963 film, America America is a tribute to the immigrant experience of his own forebears, and has relevance to the refugee crisis of today. In stark black and white cinematography, the film provides insight into the refugee-immigrant experience, personified in Stavros, a young man longing for freedom, obsessed with an idealized America. His hope and innocence cannot safeguard him. His memories of his happy childhood and loving family create idealizing transferences to a world of others who manipulate and betray him as he undertakes his quest. Eventually he too learns to manipulate and betray, unconsciously identifying with the aggressor. History will offer ethical challenges, the black and white cinematography mirroring the black and white perception of good and bad, the shades of grey evoking a maturation of understanding.

    This article described the how the Canadian company Gran Tierra Energy has expanded its operations to Australia and Colombia in South America. The companies 3 main criteria for judging its overseas projects include good geology, good fiscal terms and stable government policies. As a petroleum geologist, the president of the company gained expertise while exploring for and producing oil in North Africa, in Southeast Asia, and in Alaska. The experience laid the foundation for the company's success overseas. The challenges associated with overseas work were discussed, with particular reference to environmental liability, Aboriginal issues and planning. Companies are drawn to overseas operations primarily because of an expectation to create more value per dollar invested, compared to domestic opportunities. International operators face complexities that demand understanding of everything from tricky tax laws, difficulties repatriating proceeds, and logistical and technical challenges of expropriation of assets. The rewards, however, include huge resource potential, fiscal incentives, market opportunities and joint venture opportunities. 5 figs.

    The range of business opportunities currently available for the midstream oil and gas business were discussed with particular focus on storage opportunities. Alberta Energy Co. (AEC) Ltd.'s two midstream business units include AEC Pipelines and Gas Processing, and AEC Storage and Hub Services. These two businesses provide the company with good investment returns, stable cash flow, and some significant strategic synergies with their exploration and production businesses. In 1988, the AECO C Hub in southeastern Alberta was created as an outgrowth of AEC's gas production operations on the Suffield block, where they had depleted gas reservoirs with high rock quality suitable for high deliverability storage. With the AECO C Hub, AEC was able to offer firm storage contracts of from 1 to 20 years, and to introduce short term interruptible parking and lending services, title exchange, a spot price index for greater price discovery, and an electronic nomination system. AEC is currently completing construction of their second commercial storage facility, the Wild Goose project, in northern California. D ebottlenecking' the Western Canada supply basin should provide additional opportunities for further expansion not only for AEC but also for other midstream service providers. Opportunities are especially available in the areas of new storage facilities to serve location-specific needs, replacement of declining storage capacity, replacement of retiring facilities, technological optimization of existing facilities, more flexible, higher deliverability facilities and commercial optimization of existing facilities. A map of the hubs and market centres of North America are included. 5 figs

    Population aging represents a worldwide challenge. In Ibero-America (Spain, Portugal, and the American countries in which the Spanish or Portuguese language are spoken), the number of older adults is growing, leading to an increase in aging-related diseases such as cancer. Older adults already account for half of all cancer cases in Ibero-America, and this proportion will continue to increase. Furthermore, Ibero-American healthcare systems are not adequately prepared to provide care for older adults with cancer, mainly due to a lack of resources and generalized paucity of geriatric training for healthcare providers. Across the region, several clinical initiatives, educational activities and research collaborations have been established to set the foundations of Ibero-American geriatric oncology and to increase the geriatric knowledge among healthcare providers. This article provides an overview of the current landscape of geriatric oncology in Ibero-America, highlighting its critical challenges, opportunities for improvement and collaboration, and future directions.

    The rapid advances in information technology and communication bandwidth have spawned an equally rapid development of clinical teleradiology. Current computer technology and communication capability allow easy transfer of diagnostic images, of any complexity, to any location in the world. This provides the opportunity to acquire swift primary and secondary diagnostic opinions from the remotest of locations, often at economically attractive rates, with the potential for easing the burden on hard-pressed departments of radiology. However, this comes at the potential cost of distancing the clinical radiologist from the patient, with consequent impact upon direct clinical care. As this technology advances across the world, it is vital that UK radiologists are familiar with the clinical implications, the medicolegal framework within which the field operates and the associated governance issues. This paper reviews current practice and discusses the associated risks

    Climate change presents a complex set of challenges for natural resource managers across North America. Despite recognition that climate change poses serious threats to species, ecosystems, and human communities, implementation of adaptation measures is not yet happening on a broad scale. Among different regions, a range of climate change trajectories, varying political contexts, and diverse social and ecological systems generate a myriad of factors that can affect progress on climate change adaptation implementation. In order to understand the general versus site-specific nature of barriers and opportunities influencing implementation, we surveyed and interviewed practitioners, decision-makers, and scientists involved in natural resource management in four different North American regions, northern Ontario (Canada), the Adirondack State Park (US), Arctic Alaska (US), and the Transboundary Rocky Mountains (US and Canada). Common barriers among regions related to a lack of political support and financial resources, as well as challenges related to translating complex and interacting effects of climate change into management actions. Opportunities shared among regions related to collaboration, funding, and the presence of strong leadership. These commonalities indicate the importance of cross-site learning about ways to leverage opportunities and address adaptation barriers; however, regional variations also suggest that adaptation efforts will need to be tailored to fit specific ecological, political, social and economic contexts. Comparative findings on the similarities and differences in barriers and opportunities, as well as rankings of barriers and opportunities by region, offers important contextual insights into how to further refine efforts to advance adaptation actions in those regions.

  8. Future challenges for parasitology: vector control and one health in the Americas.

    Science.gov (United States)

    Little, Susan E

    2013-08-01

    "One Health" is a term that encapsulates and underscores the inherent interrelatedness of the health of people, animals, and the environment. Vector-borne infections are central in one health. Many arthropod vectors readily feed on humans and other animals, serving as an ideal conduit to move pathogens between a wide spectrum of potential hosts. As ecological niches flux, opportunities arise for vectors to interact with novel species, allowing infectious agents to broaden both geographic and host ranges. Habitat change has been linked to the emergence of novel human and veterinary disease agents, and can dramatically facilitate expansion opportunities by allowing existing vector populations to flourish and by supporting the establishment of new pathogen maintenance systems. At the same time, control efforts can be hindered by the development of parasiticide and pesticide resistance, foiling efforts to meet these challenges. Using examples drawn from representative diseases important in one health in the Americas, including rickettsial infections, Lyme borreliosis, Chagas disease, and West Nile virus, this paper reviews key aspects of vector-borne disease maintenance cycles that present challenges for one health in the Americas, including emergence of vector-borne disease agents, the impact of habitat change on vector-borne disease transmission, and the complexities faced in developing effective control programs. Novel strategies will be required to effectively combat these infections in the future if we are to succeed in the goal of fostering an environment which supports healthy animals and healthy people.

  9. Freud's antipathy to America.

    Science.gov (United States)

    Warner, S L

    1991-01-01

    Freud first saw this in America's attitude toward the use of cocaine. It was freely and legally used and even promoted by American physicians as beneficial in many medical conditions. Freud was first swept along by America's prococaine enthusiasm. He narrowly missed destroying his own medical reputation by his continuing close connection and advocacy of cocaine. Freud made his only visit to America in 1909. Despite the success of his visit and the congeniality of Americans toward him, he was already programmed toward a negative response. He allowed minor everyday inconveniences and cultural differences to spoil the trip for him. The chronic intestinal distress that had bothered him previously now was labelled as his "American dyspepsia." He developed additional reasons for disliking America. They accepted his three key dissenters, Adler, Jung, and Rank. He even believed that these three men achieved greater notoriety and popularity in America than he did. In fact, the Freudian psychoanalytic movement became much larger and more powerful in America than did the followings of any or all of his defectors. Freud did not like the shortcuts and lack of mastery of the basics of psychoanalysis that he believed happened in America. Some of this was true, but it was mainly exaggerated in Freud's mind. The gold of psychoanalysis was never transformed into a practical but deficient psychoanalytic alloy as Freud feared it might. There was a genuine disagreement about whether a psychoanalyst should have to become a medical doctor or not. It was a complicated issue in America because of laws that said that doing psychoanalysis was practicing medicine. Freud viewed the American stand against recognizing lay analysts as more evidence of American's being a rebellious son. Economic factors also played a significant factor in Freud's dislike of America. Freud was initially enthusiastic about President Wilson and his plans for peace. He found after World War I that all of his savings

    The purpose of this study was to analyze characteristics of individuals working in the profession of neuropsychology in Latin America in order to understand their background, professional training, current work situation, assessment and diagnostic procedures used, rehabilitation techniques employed, population targeted, teaching responsibilities, and research activities. A total of 808 professionals working in neuropsychology from 17 countries in Latin America completed an online survey between July 2013 and January 2014. The majority of participants were female and the mean age was 36.76 years (range 21-74 years). The majority of professionals working in neuropsychology in Latin America have a background in psychology, with some additional specialized training and supervised clinical practice. Over half work in private practice, universities, or private clinics and are quite satisfied with their work. Those who identify themselves as clinicians primarily work with individuals with learning problems, ADHD, mental retardation, TBI, dementia, and stroke. The majority respondents cite the top barrier in the use of neuropsychological instruments to be the lack of normative data for their countries. The top perceived barriers to the field include: lack of academic training programs, lack of clinical training opportunities, lack of willingness to collaborate between professionals, and lack of access to neuropsychological instruments. There is a need in Latin America to increase regulation, improve graduate curriculums, enhance existing clinical training, develop professional certification programs, validate existing neuropsychological tests, and create new, culturally-relevant instruments.

Investigation for this report was conducted via publications related to home energy upgrade market delivery approaches, and a series of interviews with subject matter experts (contractors, consultants, program managers, manufacturers, trade organization representatives, and real estate agents). These experts specified technical barriers and gaps, and offered suggestions for how the technical community might address them. The potential benefits of home energy upgrades are many and varied: reduced energy use and costs; improved comfort, durability, and safety; increased property value; and job creation. Nevertheless, home energy upgrades do not comprise a large part of the overall home improvement market. Residential energy efficiency is the most complex climate intervention option to deliver because the market failures are many and transaction costs are high (Climate Change Capital 2009). The key reasons that energy efficiency investment is not being delivered are: (1) The opportunity is highly fragmented; and (2) The energy efficiency assets are nonstatus, low-visibility investments that are not properly valued. There are significant barriers to mobilizing the investment in home energy upgrades, including the 'hassle factor' (the time and effort required to identify and secure improvement works), access to financing, and the

  20. Latin America second only to Asia in petrochemical prospects

    International Nuclear Information System (INIS)

    Krenek, M.R.

    1995-01-01

    The opportunity in Asia for petrochemical companies generally is well known among global players in the industry. Conventional wisdom dictates that most companies at least consider investing in Asia, and for good reason, in most cases. The more aggressive, growth-oriented companies, however, already are attempting to discover the ''next Asia,'' if there is such a thing. Latin America has been nominated as one of the less developed regions that might inherit the Asia/Pacific region's enviable position. This nomination, however, was made before the Mexican financial crisis and the burgeoning pressure on the currencies of Brazil and Argentina. In light of current events, can Latin America still be considered the next Asia, and, if so, what opportunities will follow the devaluation of the Mexican peso? An analysis of the economic and political factors affecting the petrochemical industry in Latin America indicates that the region still hold excellent prospects for petrochemical companies

Seoul: Purǔn Yeoksa, 2012.Research on U.S.–South Korean relations has continued steadily over the decades, especially in the fields of history and literature, resulting in many notable studies. However, the general tendency of this scholarship has been to introduce and analyze the United States as a discrete entity. While this perspective is useful in some regards, it is also necessary to investigate how this entity was felt, perceived, and constructed by those on the receiving end. By shifting the focus from “what America was in South Korea” to “how America was imagined in South Korea,” Sei-Jin Chang’s Imagined America: How National Narratives of Korea Have Been Constructed since August 1945 provides an insightful approach to this issue of complexity.

  3. Biomass energy in Central America

    International Nuclear Information System (INIS)

    Blanco, J.M.

    1995-01-01

    The objective of this paper is to introduce the concept of biomass to energy issues and opportunities in Central America. In this region, made up of seven countries (Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua and Panama), the biomass sector has the potential to play a crucial role in alleviating the environmental and development predicaments faced by all economies of the region. This paper assesses the available biomass resources at the regional and country levels and gives an overview of the current utilization of biomass fuels. It also describes the overall context in which the biomass-to-energy initiatives are immersed. At the regional level, biomass energy consumption accounts for more than 50% of total energy consumption. In regard to the utilization of biomass for energy purposes, it is clear that Central America faces a critical juncture at two levels, both mainly in rural areas: in the productive sector and at the household level. The absence of sustainable development policies and practices has jeopardized the availability of biomass fuels, particularly wood. Firewood is an important source of energy for rural industries such as coffee processing, which is one of the largest productive activities in the region. This paper comments on some of the most successful technological innovations already in place in the region, for instance, the rapid development of co-generation projects by the sugar cane industry, especially in El Salvador and Guatemala, the substitution of coffee husks for firewood in coffee processing plants in Costa Rica and El Salvador and the sustainable use of pine forests for co-generation in Honduras. Only one out of every two inhabitants in Central America now has access to electricity from the public grid. Biomass fuels, mainly firewood but also, to a lesser extent, other crop residues such as corn stalks, are the main source of energy for cooking and heating by most of the population. (It is foreseen that by the end

    To evaluate environmental obesogenic-related factors, such as physical activity in neighborhoods and schools, nutritional behavior, and intervention programs. Critical analysis of literature with personal point of view from infant obesity experts and political advisors for public intervention. Although obesity is a public health problem affecting several age groups, it is among children and adolescents that it plays a more important role, due to treatment complexity, high likelihood of persistence into adulthood, and association with other non-transmissible diseases while still in early age. Environment is a main component of the genesis and outcomes in the near future or long term. Modification of intake with high-density food, meal skipping, and high intake of saturated fat, sugar, and salt, associated to high levels of sedentarism are main causes of obesity. Intervention opportunities are related to modifications in political, environmental, and individual settings. School and physical activities in the educational environment are intertwined with nutrition intervention in continuous education. A critical review of some different scenarios in Latin American countries is presented. Copyright © 2016 Sociedade Brasileira de Pediatria. Published by Elsevier Editora Ltda. All rights reserved.

  14. Telecommunications: international opportunities for power utilities

    Lewis, A. [Teleglobe Canada, Ottawa, ON (Canada)

    1996-08-01

    International telecommunications services markets and trends were reviewed in an effort to identify business opportunities for Canadian power utilities. With increasing deregulation in the U.S. and Canada, and other countries around the globe, market opportunities are beginning to open up. In monopoly markets opportunities exist in providing dual infrastructures to upgrade both the power delivery services (frequently poor), and telecommunications. Billing, collection and customer service expertise might be other marketable commodities, perhaps packaged as part of a network provision project as a service to existing power and telecommunications service providers. In countries with directed competition markets local partnerships may be the only vehicle for entering the market. In managed competition markets opportunities were said to exist in cellular radio technology, as well as in switched telephone service, local, long distance, or international. In general, opportunities outside telecommunications-rich North America were considered to have better potential, due to rapid deregulation and higher current growth rates in telecommunications. Careful examination and research of the political and business environment prior to entering any of the potentially fertile areas was advised.

Changes are being introduced: in future, the focus of their work will be broadened to cover all aspects of diversity promotion.   The term "equal opportunities" has always been broader in scope than the equal treatment of men and women but this is what it has traditionally been confined to in practice. "We wanted to change how people see our mission", explains Doris Chromek-Burckhart. The word "diversity" has much wider connotations than "equal opportunities" and makes it clearer that we are also dealing with differences in nationality, religion, age, culture and physical ability”. Getting away from the old clichés is vital to ensuring equal treatment for everyone. The diversit...

  19. Cholera in the Americas.

    Science.gov (United States)

    1991-01-01

    The cholera epidemic 1st hit South America in January 1991 in the coastal town of Chancay, Peru. In 2 weeks, it spread over 2000 km of the Pacific coast. By the end of the 1st month, it had already reached the mountains and tropical forests. By August 1991, cholera cases were reported in order of appearances in Ecuador, Colombia, Chile, Brazil, the US, Mexico, Guatemala, Bolivia, and El Salvador. Health authorities still do not know how it was introduced into South America. The case fatality rate has remained at a low of 1%, probably due to the prompt actions of health authorities in informing the public of the epidemic and what preventive cautions should be taken. This epidemic is part of the 7th pandemic which originated in Celebes, Indonesia in 1961. Cholera can spread relatively unchecked in Latin America because sewage in urban areas is not treated even though they do have sewage collection systems. The untreated wastewater enters rivers and the ocean. Consumption of raw seafood is not unusual and has been responsible for cholera infection in some cases. In fact, many countries placed import restrictions on marine products from Peru following the outbreak at a loss of $US10-$US40 million. Municipal sewage treatment facilities, especially stabilization ponds, would prevent the spread of cholera and other pathogens. In rural areas, pit latrines located away from wells can effectively dispose of human wastes. Most water supplies in Latin America are not disinfected. Disinfection drinking water with adequate levels of chlorine would effectively destroy V. cholera. If this is not possible, boiling the water for 2-3 minutes would destroy the pathogen. Any cases of cholera must be reported to PAHO. PAHO has responded to the outbreak by forming a Cholera Task Force and arranged transport of oral rehydration salts, intravenous fluids, antibiotics, and other essential medical supplies.

    2009-12-01

    Basal shear tractions, as generated by mantle convection, are likely to affect the stress field over western North America, and hence, influence the deformation of the North American lithosphere. Earlier studies (Humphreys & Coblentz (2007)) have argued for the importance of shear tractions beneath the continent, but at a reduced amplitude from those predicted by Becker & O'Connell (2001). However, these tractions did not take into account the existence of lateral viscosity variations (LVVs) beneath North America, resulting from strong cratonic root and weak plate margin. We evaluate the tractions and the resulting stresses over North America by incorporating LVVs in a global, high resolution, finite element convection code, CitcomS. Since our ultimate goal is to match observables, such as plate motions and geoid, in addition to stresses, we perform a global inversion for both radial and lateral viscosity variations and choose the viscosity structures that yield a good fit simultaneously to both the global geoid and plate motions. We evaluate the tractions and corresponding stress field from those models. We also attempt to incorporate the effects of gravitational potential energy (GPE) in our convection model. The combined stress field from GPE and tractions are compared to stress observations, such as the World Stress Map.

    2011-04-01

    Full Text Available This article offers a perspective of the strategies adopted by the main industrial powers during the 1950s and 1960s to penetrate the Spanish market. Under the influence of the Cold War, international cooperation between the United States of America and Western Europe and the emergence of a developing country, foreign corporate groups sought support from their governments to conquer new business opportunities in Spain. Despite the entrance barriers, the 50s bore witness to how these groups adopted positions based on the conviction that Franco’s regime would eventually end up giving way to economic liberalism, thus returning Spain to the international economy, hence multiplying expectations on investments and profit. An outward- looking vantage point helps to understand the complexity of an economy that was subject to the intervention of an authoritarian state while in a stage of accelerated growth. External relationships were forged based on market strategies.

  3. North America and Asia Pacific LNG markets

    International Nuclear Information System (INIS)

    Pirie, J.D.

    1997-01-01

    The liquefied natural gas (LNG) export opportunities in the Asia Pacific market were reviewed. Some of the differences that affect a North American LNG projects compared to more typical LNG projects were also outlined. The two main aspects of the LNG market in North America include the establishment of LNG import terminals on the east and southern coasts of the United States and the development of export oriented LNG projects. The Pac-Rim LNG project calls for initial delivery to South Korea of 4.0 MTPA by the end of 2000. A large LNG project has also been proposed for the year 2005 which would use Prudhoe Bay gas. Generally, in North America, there is little use for large scale LNG import projects because of the vast pipeline network that delivers gas reliably and at low cost anywhere in North America. However, LNG remains a good alternative for the Asia Pacific region because of the lack of a pipeline network. Also, Japan, Korea and Taiwan, the three main centers for LNG demand, have no domestic energy supplies and rely on imported energy sources. China is another major market opportunity for LNG. The Pac-Rim LNG project differs from others of its kind in that usually, an LNG project is based on the availability of large reservoirs of natural gas owned by state governments and involves production agreements with multi-national oil and gas companies. This scenario is simply not possible in Canada's deregulated environment. In contrast, the existence of upstream facilities, technical expertise, and low capital costs, hence reduced risks and time to develop an LNG project, gives Canada significant advantages. 3 tabs., 3 figs

  6. Decadal opportunities for space architects

    Science.gov (United States)

    Sherwood, Brent

    2012-12-01

    A significant challenge for the new field of space architecture is the dearth of project opportunities. Yet every year more young professionals express interest to enter the field. This paper derives projections that bound the number, type, and range of global development opportunities that may be reasonably expected over the next few decades for human space flight (HSF) systems so those interested in the field can benchmark their goals. Four categories of HSF activity are described: human Exploration of solar system bodies; human Servicing of space-based assets; large-scale development of space Resources; and Breakout of self-sustaining human societies into the solar system. A progressive sequence of capabilities for each category starts with its earliest feasible missions and leads toward its full expression. The four sequences are compared in scale, distance from Earth, and readiness. Scenarios hybridize the most synergistic features from the four sequences for comparison to status quo, government-funded HSF program plans. Finally qualitative, decadal, order-of-magnitude estimates are derived for system development needs, and hence opportunities for space architects. Government investment towards human planetary exploration is the weakest generator of space architecture work. Conversely, the strongest generator is a combination of three market drivers: (1) commercial passenger travel in low Earth orbit; (2) in parallel, government extension of HSF capability to GEO; both followed by (3) scale-up demonstration of end-to-end solar power satellites in GEO. The rich end of this scale affords space architecture opportunities which are more diverse, complex, large-scale, and sociologically challenging than traditional exploration vehicle cabins and habitats.

    Plant phenological observations and networks in North America have been largely local and regional in extent until recent decades. In the USA, cloned plant monitoring networks were the exception to this pattern, with data collection spanning the late 1950s until approximately the early 1990s. Animal observation networks, especially for birds have been more extensive. The USA National Phenology Network (USA-NPN), established in the mid-2000s is a recent effort to operate a comprehensive national-scale network in the United States. In Canada, PlantWatch, as part of Nature Watch, is the current national-scale plant phenology program.

Timekeeping is essential to everyday life, and thus is the most measured physical quantity in modern societies. Time can also be measured with less uncertainty and more resolution than any other physical quantity. The measurement of time is of the utmost importance for many applications, including: global navigation satellite systems, communications networks, electric power generation, astronomy, electronic commerce, and national defense and security. This paper discusses how time is kept, coordinated, and disseminated in the Americas.

  12. Conservation and Development in Latin America and Southern Africa: Setting the Stage

    Directory of Open Access Journals (Sweden)

    2012-06-01

    Full Text Available The articles in this Special Feature stem from a 2010 conference (Bridging Conservation and Development in Latin America and Africa organized by the University of Florida's Tropical Conservation Development Program, Center for African Studies, and Center for Latin American Studies. The conference involved researchers and practitioners from Africa and Latin America focused on the complex and evolving relationship between conservation and development. The conference provided bridges between academics and non-academics, conservation and development, and theory and practice. The resulting comparative analyses focus on: empowerment of local institutions; enhanced capacity of local and regional stakeholders through a recognition and validation of local knowledge systems and the creation of knowledge networks; understanding of social and natural landscapes, history, contexts, and their evolution; and the roles of economic and market forces in shaping opportunities for using market-based incentives to promote conservation and development. In this introductory article we propose a conceptual framework based on the six connected pillars of natural resource characteristics, interactions of social actors, governance and participation, politics, information exchange, and economic issues that support spaces for both conflicts and synergies between conservation and development goals. Our goal is to foster informed dialogue and social learning to promote sustainability.

  13. Can Latin America fill the U.S. polyolefin deficit?

    International Nuclear Information System (INIS)

    Sagel, E.

    2006-01-01

    Strategic issues for the North American polyolefin industry were discussed with reference to oil and gas price forecasts, oil capacity increases, and high density polyethylene production and ethylene integration costs. The overall polyolefin trade balance in North America was also explored. It was cautioned that unless a significant amount of new capacity is built in the United States, it is anticipated that by 2008, the United States will become a net importer of polyolefin resins. Currently exported product will be used increasingly in the domestic market to meet demand growth. This shift from being a net exporter of resins can be attributed to the high cost of feedstocks and the lack of investment in new capacity throughout the region. In contrast, there have been several proposals for new capacity in Latin America in the past several years. Since there is already an important level of commerce and trade between North and South America, countries with access to the Caribbean basin, are logistically well situated to serve the North American market. The availability of low cost feedstocks in countries such as Trinidad, Venezuela and Bolivia add to the attractiveness of the region for the development of new petrochemical capacity. This paper examined the status of the different proposed projects in Latin America and analyzed the potential opportunities that exist for North American producers to collaborate in those projects. The general trade balance of the continent was reviewed in order to verify if the traditional seclusion of America's polyolefin market can be maintained in the future. It was concluded that even if all projects in Latin America are launched, the Americas will still be in a net deficit position. Under the right circumstances, the Middle East will be the global supplier of commodity polyolefins that could extend to the Americas. It was emphasized that companies should be prepared for feedstock advantaged investments, alliances, acquisitions and

    The freshwater and marine fish faunas of South America are the most diverse on Earth, with current species richness estimates standing above 9100 species. In addition, over the last decade at least 100 species were described every year. There are currently about 5160 freshwater fish species, and the estimate for the freshwater fish fauna alone points to a final diversity between 8000 and 9000 species. South America also has c. 4000 species of marine fishes. The mega-diverse fish faunas of South America evolved over a period of >100 million years, with most lineages tracing origins to Gondwana and the adjacent Tethys Sea. This high diversity was in part maintained by escaping the mass extinctions and biotic turnovers associated with Cenozoic climate cooling, the formation of boreal and temperate zones at high latitudes and aridification in many places at equatorial latitudes. The fresh waters of the continent are divided into 13 basin complexes, large basins consolidated as a single unit plus historically connected adjacent coastal drainages, and smaller coastal basins grouped together on the basis of biogeographic criteria. Species diversity, endemism, noteworthy groups and state of knowledge of each basin complex are described. Marine habitats around South America, both coastal and oceanic, are also described in terms of fish diversity, endemism and state of knowledge. Because of extensive land use changes, hydroelectric damming, water divergence for irrigation, urbanization, sedimentation and overfishing 4-10% of all fish species in South America face some degree of extinction risk, mainly due to habitat loss and degradation. These figures suggest that the conservation status of South American freshwater fish faunas is better than in most other regions of the world, but the marine fishes are as threatened as elsewhere. Conserving the remarkable aquatic habitats and fishes of South America is a growing challenge in face of the rapid anthropogenic changes of the 21

  16. Outlook for hydropower in Latin America and the Caribbean

    Energy Technology Data Exchange (ETDEWEB)

    Sanchez-Sierra, G. (OLADE, Quito (Ecuador))

    1993-02-01

    In the last two decades, the Latin America/Carribean region has become increasingly dependent on electricity to meet growing demands for energy. Hydropower is the prevailing source for meeting this need. Hydroelectric generation increased at an annual average rate of nearly 9% between 1971 and 1989. HYdro now provides more than two-thirds of total electric power generated in Latin America and the Caribbean. The only other predominant source used for electric generation is fossil fuels. In this region there are several trends developing. They include: developing more small hydro facilities, opportunities for sharing water resources, an interest in changing the approach to water use regulation, and possibilities for more participation by the private sector. Overall, hydro appears to have a favorable competitive position in the power industry in the Latin America/Caribbean region.

  18. Industrial opportunities - offshore

    International Nuclear Information System (INIS)

    Gerrits, D.J.

    1998-01-01

    Industrial opportunities available in the Canadian offshore petroleum industry are discussed. Oil has been produced offshore from Nova Scotia since 1992, and offshore from Newfoundland since 1997. Special needs that must be addressed in offshore operations in eastern Canada such as the cold North Atlantic environment, isolation, logistics, safety, and quality assurance, are examined. The most obvious opportunities lie with the designing, building and installing the facilities needed to extract oil and gas from beneath the sea floor and transport it to market. However, there are also opportunities in designing and fabricating clothing, customized food containers and other equipment for offshore needs. Short term opportunities also exist in the decommissioning of depleted production fields and their facilities. One of the greatest obstacles facing new entrants into the offshore oil and gas industry is the lack of a track record. To meet this challenge, the ability to seek out partners to pursue local and international opportunities through joint ventures, strategic alliances and technology sharing partnering arrangements is of great importance. It may be the difference between success and failure. 6 figs

  19. Anaglyph, South America

    Science.gov (United States)

    2003-01-01

    This anaglyph (stereoscopic view) of South America was generated with data from the Shuttle Radar Topography Mission (SRTM). It is best viewed at or near full resolution with anaglyph glasses. For this broad view the resolution of the data was first reduced to 30 arcseconds (about 928 meters north-south but variable east-west), matching the best previously existing global digital topographic data set called GTOPO30. The data were then resampled to a Mercator projection with approximately square pixels (about one kilometer, or 0.6 miles, on each side). Even at this decreased resolution the variety of landforms comprising the South American continent is readily apparent.Topographic relief in South America is dominated by the Andes Mountains, which extend all along the Pacific Coast. These mountains are created primarily by the convergence of the Nazca and South American tectonic plates. The Nazca Plate, which underlies the eastern Pacific Ocean, slides under western South America resulting in crustal thickening, uplift, and volcanism. Another zone of plate convergence occurs along the northwestern coast of South America where the Caribbean Plate also slides under the South American Plate and forms the northeastern extension of the Andes Mountains.East of the Andes, much of northern South America drains into the Amazon River, the world's largest river in terms of both watershed area and flow volume. Topographic relief is very low in much of the Amazon Basin but SRTM data provide an excellent detailed look at the basin's three-dimensional drainage pattern, including the geologic structural trough (syncline) that hosts the eastern river channel.North of the Amazon, the Guiana Highlands commonly stand in sharp contrast to the surrounding lowlands, indeed hosting the world's tallest waterfall, Angel Falls (979 meters or 3212 feet). Folded and fractured bedrock structures are distinctive in the topographic pattern.South of the Amazon, the Brazilian Highlands show a mix of

    National Laboratories often have unique facilities that cannot be normally found at universities, and that provide unique opportunities to perform research using world class instrumentation in collaboration with teams of experts. This synergy of expertise and world-class facilities also offers unique opportunities for mentoring and training of students in settings different from the university environment. In this talk I will discuss the opportunities of scientific research, mentoring and training at the Spallation Neutron Source (SNS) and the High Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratory. The SNS is the world's most intense pulsed accelerator-based neutron source, the HFIR is the highest flux reactor-based neutron source for condensed matter research in the United States, the combination of these provides neutron scattering capabilities unavailable anywhere else in the world. The SNS and the HFIR at ORNL are funded by the Division of Scientific User Facilities, Office of Basic Energy Sciences, US. Department of Energy.

  1. Fermilab and Latin America

    International Nuclear Information System (INIS)

    Lederman, Leon M.

    2006-01-01

    As Director of Fermilab, starting in 1979, I began a series of meetings with scientists in Latin America. The motivation was to stir collaboration in the field of high energy particle physics, the central focus of Fermilab. In the next 13 years, these Pan American Symposia stirred much discussion of the use of modern physics, created several groups to do collaborative research at Fermilab, and often centralized facilities and, today, still provides the possibility for much more productive North-South collaboration in research and education. In 1992, I handed these activities over to the AAAS, as President. This would, I hoped, broaden areas of collaboration. Such collaboration is unfortunately very sensitive to political events. In a rational world, it would be the rewards, cultural and economic, of collaboration that would modulate political relations. We are not there yet

    Oncology nursing offers nurses a wide range of opportunities. Nurses need a wide range of skills in order to care for patients who may have acute oncological illnesses or require palliative care. The nature of the nurse/patient relationship can be intense. Nurses generally find this enhances job satisfaction. The pressures exerted on nurses working in oncology can be immense. Oncology nursing is rewarding but very demanding and therefore the nurse has to be resourceful. Early career planning is advisable to take advantage of the opportunities that are currently available.

  6. Central America's shrinking forests.

    Science.gov (United States)

    1992-01-01

    This news brief reports that 66% of deforestation in Central America has happened in the past 40 years, based on World Conservation Union (WCU) data. Deforestation is expected to continue. The population of Central America and Mexico grew by 28% between 1977 and 1987. Growth is decreasing but remains high at 2.5% in all countries of the region except Panama. 29 million was the regional population in 1990; the projection is for 63 million by 2025. Population is migrating to urban centers. Forests declined by 13% and croplands increased from 4% to 13% of total land area and pasture land from 2% to 37%. There was an increase in unproductive land from 145 to 24%, i.e., 50% of El Salvador's land had soil degradation as does 30% of Guatemala's. In addition to deforestation and soil degradation, there has been soil erosion leading to sedimentation buildup near dam sites and in rivers, which diminishes hydroelectric power capability. Silting also affects groundwater resources, which impact on a safe drinking water supply. Population growth results in increased demand for fuelwood, urban land, and agricultural land. New techniques practiced widely are needed in order to meet the region's needs or demands. Slowing population growth buys time for adjusting to the necessary changes needed for sustaining the region's population. WCU urges conservation organizations to raise awareness about the role population plays in environmental degradation, and to support efforts to reduce birth rates. Women's status needs to be improved through income-generating projects, for instance, and cooperation is needed between conservation groups and organizations involved with improving maternal and child health.

    Barely 10-20% of patients with metastatic colorectal cancer (mCRC) receive a clinical benefit from the use of anti-EGFR monoclonal antibodies (mAbs). We hypothesized that this could depends on their efficiency to reduce Store Operated Calcium Entry (SOCE) that are known to enhance cancer cells. In the present study, we demonstrate that SOCE promotes migration of colon cancer cell following the formation of a lipid raft ion channel complex composed of TRPC1/Orai1 and SK3 channels. Formation of this complex is stimulated by the phosphorylation of the reticular protein STIM1 by EGF and activation of the Akt pathway. Our data show that, in a positive feedback loop SOCE activates both Akt pathway and SK3 channel activity which lead to SOCE amplification. This amplification occurs through the activation of Rac1/Calpain mediated by Akt. We also show that Anti-EGFR mAbs can modulate SOCE and cancer cell migration through the Akt pathway. Interestingly, the alkyl-lipid Ohmline, which we previously showed to be an inhibitor of SK3 channel, can dissociated the lipid raft ion channel complex through decreased phosphorylation of Akt and modulation of mAbs action. This study demonstrates that the inhibition of the SOCE-dependent colon cancer cell migration trough SK3/TRPC1/Orai1 channel complex by the alkyl-lipid Ohmline may be a novel strategy to modulate Anti-EGFR mAb action in mCRC.

Additional information about the workshop, including relevant reading and presentations on multiphysics issues in applications, algorithms, and software, is available via https://sites.google.com/site/icismultiphysics2011/. We consider multiphysics applications from algorithmic and architectural perspectives, where 'algorithmic' includes both mathematical analysis and computational complexity and 'architectural' includes both software and hardware environments. Many diverse multiphysics applications can be reduced, en route to their computational simulation, to a common algebraic coupling paradigm. Mathematical analysis of multiphysics coupling in this form is not always practical for realistic applications, but model problems representative of applications discussed herein can provide insight. A variety of software frameworks for multiphysics applications have been constructed and refined within disciplinary communities and executed on leading-edge computer systems. We examine several of these, expose some commonalities among them, and attempt to extrapolate best practices to future systems. From our study, we summarize challenges and forecast opportunities. We also initiate a modest suite of test problems encompassing features present in many applications.

    Minato, Akio; Nishimura, Satoshi; Brown, Neil W.

    2007-01-01

    This report assesses the market potential and identifies a number of potential paths for developing the small nuclear reactor business. There are several potential opportunities identified and evaluated. Selecting a specific approach for the business development requires additional information related to a specific market and sources of capital to support the investment. If and how a market for small nuclear plants may develop is difficult to predict because of the complexity of the economic and institutional factors that will influence such development. Key factors are; economics, safety, proliferation resistance and investment risk. The economic and political interest of any of the identified markets is also dependent on successful demonstration of the safety and reliability of small nuclear reactor. Obtaining a US-NRC Standard Design approval would be an important development step toward establishing a market for small reactors. (authors)

    A Geopark is a territory delimited part of a holistic concept of protection, education and sustainable development, based on geological sites of particular importance, rarity or aesthetic geological sites. A Geopark achieves its goals through three main areas: geoconservation, education and geotourism. The first network of Geoparks born in Europe in 2000, and from 2004 UNESCO is promoting the creation of a Global Geoparks Network (Global Geoparks Network, GGN ). Currently, there are 64 Global Geoparks in 19 countries, and the movement is in full development. In Latin America there is hardly Araripe Geopark in Brazil. Presented in this work, projects and studies related to the development of Geoparks in Argentina, Brazil, Chile, Costa Rica, Peru and Venezuela. We understand that Colombia, Cuba, Ecuador, Mexico and Nicaragua have projects in this line, but the details are not yet readily available. The authors invite geoscientists and professionals in related fields to join a movement for the creation of the Latin American Network of Geoparks, intended as a framework for the conservation, sustainable use and disclosure of our national geological heritage

  5. Wind Powering America

    2001-01-01

    At the June 1999 Windpower Conference, the Secretary of Energy launched the Office of Energy Efficiency and Renewable Energy's Wind Powering America (WPA) initiative. The goals of the initiative are to meet 5% of the nation's energy needs with wind energy by 2020 (i.e., 80,000 megawatts installed), to double the number of states that have more than 20 megawatts (MW) of wind capacity to 16 by 2005 and triple it to 24 by 2010, and to increase wind's contribution to Federal electricity use to 5% by 2010. To achieve the Federal government's goal, DOE would take the leadership position and work with its Federal partners. Subsequently, the Secretary accelerated the DOE 5% commitment to 2005. Achieving the 80,000 MW goal would result in approximately$60 billion investment and$1.5 billion of economic development in our rural areas (where the wind resources are the greatest).

    Peritoneal dialysis has a high acceptance rate in Latin America, thus the knowledge concerning complication patterns is of great relevance. This work reviews Latin American data on peritonitis, the most serious complication of peritoneal dialysis. The incidence of peritonitis has been reduced over time, concomitantly with the incorporation of safer exchange systems and the use of prophylactic measurements. Today, rates lower than 1 episode per 24 patient-months are commonly reported. Furthermore, changes in causative organisms have been observed, with predominance of Staphylococcus aureus up through the mid-1990s, as well as increases in coagulase-negative staphylococcus and participation of gram negatives. However, the prevalence of S. aureus is still high, due possibly to climatic conditions and the elevated prevalence of carriers. Resolution rate varies from 55% to 78%, transfer to hemodialysis from 10.9% to 15.4%, and death in 3% to 9.9% of cases. Outcome is worse in S. aureus episodes compared to those with coagulase-negative staphylococcus, despite the higher percentage of oxacillin-resistant strains among the former. In general, despite socioeconomic or climatic conditions, our results are similar to those in developed countries, perhaps as a consequence of technological improvements and/or center expertise.

  7. Wind Powering America

    At the June 1999 Windpower Conference, the Secretary of Energy launched the Office of Energy Efficiency and Renewable Energy's Wind Powering America (WPA) initiative. The goals of the initiative are to meet 5% of the nation's energy needs with wind energy by 2020 (i.e., 80,000 megawatts installed), to double the number of states that have more than 20 megawatts (MW) of wind capacity to 16 by 2005 and triple it to 24 by 2010, and to increase wind's contribution to Federal electricity use to 5% by 2010. To achieve the Federal government's goal, DOE would take the leadership position and work with its Federal partners. Subsequently, the Secretary accelerated the DOE 5% commitment to 2005. Achieving the 80,000 MW goal would result in approximately $60 billion investment and $1.5 billion of economic development in our rural areas (where the wind resources are the greatest). The purpose of this paper is to provide an update on DOE's strategy for achieving its goals and the activities it has undertaken since the initiative was announced.

  8. Introduction - Latin America and nuclear energy

    International Nuclear Information System (INIS)

    1976-01-01

    For the second time in its history, the International Atomic Energy Agency is holding its General Conference in Latin America. The first was in Mexico City in September 1972; this September the Conference meets in Rio de Janeiro (in each case, the arrangement has been possible because of the very generous hospitality of the Host Government). Therefore, it is an appropriate occasion to devote a section of the IAEA Bulletin to nuclear energy in Latin America. The vast Latin American region presents many special opportunities for the introduction of nuclear science and technology. The first mission that the IAEA sent out, as far back as 1957, was to Latin America to promote co-operation in using radioisotope techniques. Today, these techniques are widely used by hospitals and medical research institutions throughout the region. Besides their medical applications, isotope techniques are also proving to be very useful in studying soils and irrigation, improving crops and livestock, and controlling insect pests. They also help make prudent use of the underground water resources in the region which, despite its bountiful rivers and tropical forests, includes many large arid areas. The major applications of nuclear technology have come only recently to Latin America, firstly in Argentina, where a 319 MW(e) nuclear power plant began operating at Atucha in 1974. It will soon be followed by the first Brazilian nuclear power plant - a 600 MW(e) light water plant at Angra dos Reis nearing completion. Argentina is building a second power plant at Embalse, and Brazil is planning two 1200 MW(e) plants at Angra and six more 1200 MW(e) units by 1990. Mexico is building its first nuclear plant at Laguna Verde, while other countries such as Chile and Colombia are planning the introduction of nuclear power. After a relatively slow start it, therefore, seems that nuclear power will go ahead fast in the Latin American region in the 1980's and 1990's. This is not surprising. Despite

    Full Text Available Neoliberalism in Latin America. Neoliberalism and globalization had decisive influence in shaping public policies both internal and foreign in Latin America. Less state, trade and market freedoms, social goals subordinated to economic criteria, are part and parcel of the neoliberal utopia. Price stability was erected as the main social objective; import substitution resulted replaced by exports as the main source of growth. The neoliberal net results as applied to Latin America are: less growth, deindustrialization, income concentration and precarious employments. Therefore, countries public policies should try to gain autonomy to use jointly markets and public intervention in a constructive and innovative fashion.

  11. User Frustrations as Opportunities

    2012-04-01

    Full Text Available User frustrations are an excellent source of new product ideas. Starting with this observation, this article describes an approach that entrepreneurs can use to discover business opportunities. Opportunity discovery starts with a problem that the user has, but may not be able to articulate. User-centered design techniques can help elicit those latent needs. The entrepreneur should then try to understand how users are solving their problem today, before proposing a solution that draws on the unique skills and technical capabilities available to the entrepreneur. Finally, an in-depth understanding of the user allows the entrepreneur to hone in on the points of difference and resonance that are the foundation of a strong customer value proposition.

    A new role for the deregulated electric utilities in the energy services market or performance contracting markets was discussed. It was argued that in view of the long tradition of close customer contact, distribution utilities are in a good position to leverage their relationship with their customers to expand the range of products and services that the ''utility'' provides to them. Real time pricing, energy services, HVAC maintenance and operation are just some of the areas where the distribution utility''s linkage to customers could be used to good advantage. Some case histories, and a list of potential product and service opportunities in the commercial/industrial and residential sectors were provided. Some of the potential pitfalls were also identified for utilities that wish to pursue these opportunities. These pitfalls included legal, marketing, risk management and funding issues

    An analysis of factors affecting migration is presented. The authors "extend the investigation of the roles of information, intervening opportunities, and psychic costs by focussing on differences in migrant destinations with respect to the deterring effect of distance. [They develop] a reservation-wage model of migration which implies that the distance effect is weaker for high-wage destinations and stronger for low-wage destinations." The model is tested using data for Brazil, Japan, Mexico, the United States, and Venezuela. excerpt

    Actual results have shown that the Construction Industry Institute (CII) offers significant opportunities for improvement in cost, schedule, and quality on most projects, and in particular, on large projects. This paper reviews the state of the construction industry, discusses how its problems are being addressed by CII, and addresses potential opportunities through the application of CII research products. CII is meeting the challenge of the industry. Just like the challenge of Department of Energy's Super Conducting Super Collider. With $1.2 billion worth of construction to be constructed during the 90s, the opportunities for innovation appear to be great. Every effort should be made while the projects are still on the high part of cost influence curve to use modern management methods and approaches to executing its work. Proper attention to all the inputs to project design is absolutely essential. Scope definition and control techniques have been developed by CII which can be used. Work packaging for the most efficient execution of engineering and construction are available as well. Approaches, incentives, and contracting strategies have also been researched by CII. Constructability programs virtually always guarantee a savings of at least 10 percent. Partnership arrangements can reduce the size of overhead for all participants in the process and eliminate the typical adversarial climates which tend to predominate on a construction project. SSC Laboratories and the PB-MK team have the opportunity to take the initiative now to make the 21st Century SSC a construction project which is executed in the 21st Century manner

    2007-02-23

    The Clovis complex is considered to be the oldest unequivocal evidence of humans in the Americas, dating between 11,500 and 10,900 radiocarbon years before the present (14C yr B.P.). Adjusted 14C dates and a reevaluation of the existing Clovis date record revise the Clovis time range to 11,050 to 10,800 14C yr B.P. In as few as 200 calendar years, Clovis technology originated and spread throughout North America. The revised age range for Clovis overlaps non-Clovis sites in North and South America. This and other evidence imply that humans already lived in the Americas before Clovis.

The, at this point largely unexamined, plethora of possibilities going forward, a subset of which is discussed, could literally reinvent aerospace but requires triage of many possibilities. Such initial upfront homework would lengthen the Research and Development (R&D) time frame but could greatly enhance the affordability and performance of the evolved products and capabilities. Structural nanotubes and exotic energetics along with some unique systems approaches are particularly compelling.

    The demographic structure of Latin American countries (LAC) is fast approaching that of developing countries, and the predicted prevalence of dementia in the former already exceeds the latter. Dementia has been declared a global challenge, yet regions around the world show differences in both the nature and magnitude of such a challenge. This article provides evidence and insights on barriers which, if overcome, would enable the harmonization of strategies to tackle the dementia challenge in LAC. First, we analyze the lack of available epidemiologic data, the need for standardizing clinical practice and improving physician training, and the existing barriers regarding resources, culture, and stigmas. We discuss how these are preventing timely care and research. Regarding specific health actions, most LAC have minimal mental health facilities and do not have specific mental health policies or budgets specific to dementia. In addition, local regulations may need to consider the regional context when developing treatment and prevention strategies. The support needed nationally and internationally to enable a smooth and timely transition of LAC to a position that integrates global strategies is highlighted. We focus on shared issues of poverty, cultural barriers, and socioeconomic vulnerability. We identify avenues for collaboration aimed to study unique populations, improve valid assessment methods, and generate opportunities for translational research, thus establishing a regional network. The issues identified here point to future specific actions aimed at tackling the dementia challenge in LAC. PMID:29305437

  12. Inclusive education in Latin America and the Caribbean

    Directory of Open Access Journals (Sweden)

    Rosa BLANCO GUIJARRO

    2011-11-01

    Full Text Available The region of Latin America and the Caribbean is known for being the most socially unequal in the world and for this has highly segmented societies, which affects the education, integration and social cohesion of the population. Expanding opportunities for everyone to have access to quality education and developing more inclusive schools, which would educate within and for diversity, stand out as two powerful strategies in a move towards more just and democratic societies in Latin America. This paper presents a detailed analysis of the educational situation in the region from the perspective of rights and inclusion, with particular attention paid to those individuals and groups that suffer most from the impact of inequality, exclusion and marginalization. This analysis begins with an assessment the progress and challenges still to be made regarding access, attendance, quality and equity of education in Latin America. In the second part it addresses the major issues on the agenda of Inclusion in Latin America and the Caribbean.

  13. Geological-uraniferous favourability of South America

    International Nuclear Information System (INIS)

    Stipanicic, P.N.

    1984-01-01

    The South American continent includes several metallogenic provinces some of which have excellent uranium possibilities. Basically, two types of lithological complex have contributed to this favourability: the large Precambrian shields covering about 5,500,000 km 2 and the crystalline Hercynian nesocratons with about 300,000 km 2 as source rocks. Only in Argentina and Brazil has continuous uranium exploration in South America been carried out, with moderate budgets, during the last twenty-five years. In the rest of South America the search for uranium has been performed intermittently and with limited resources. However, during recent years interest has increased and more continuous operation has been recorded in some countries (Bolivia, Colombia, Chile, Peru). It can be estimated that only 20% of the favourable areas have been explored fairly intensively in Argentina and Brazil, the two most advanced uraniferous countries. Nevertheless, the uranium possibilities of South America are proved by the resources of 250,000 t U already defined (in Argentina and Brazil) for the category of production cost below US $130/kg U. The speculative uranium potential of the continent was estimated by the International Uranium Resources Evaluation Project as between 770,000 and 1,500,000 t U. Within the South American geostructural framework, five main uraniferous geological areas have been defined on the basis of the geotectonic evolution of the continent, the succession of sedimentary and magmatic processes, and the participation in them of the endogenous and exogenous phases of the uranium geochemical cycle. In this paper the principal uranium metallogenic models occurring in the above five main areas are studied together with the uranium potential of each area. The possibility of uranium recovery from these sources in relation to the respective costs of production is briefly discussed

    2011-01-01

    This communication summarizes the available data on work-related determinants of health in Central America. The Central American working population is young and moving from agriculture toward industry and services. Ethnicity, gender, migration, subemployment and precarious work, informality, rural conditions, low-level educational, poverty, ubiquitous worksite health hazards, insufficient occupational health services, low labor inspection density, and weak unions define the constellation of social determinants of workers' health in Central America. Data are, however, scanty both for hazards and work-related illnesses and injuries. Governments and industries have the responsibility of opening decent work opportunities, especially for those facing multiple inequalities in social determinants of health. A first step would be the ratification and implementation of the ILO Convention (187) on occupational safety and health by the seven national governments of the region.

Trans-Alta is a company generating 4,500 MW of electricity from coal, hydro and natural gas. It has operating facilities in Canada, Argentina and New Zealand, including extensive coal mining interests in Canada. The climate for international opportunities in the energy field were judged to be very good in view of the projected requirement for some 900,000 MW of new power generation in different parts of the world by the year 2003. The five key factors identified for international power development were: (1) using core skills to add value, (2) have a long-term focus, (3) focus on specific countries and selected regions, (4) develop strong relationships with local partners, and (5) develop appropriate projects. 2 figs

    2014-09-01

    Scrutinized from the perspective of time, the giants in the history of crystallography more than once missed a nearly obvious chance to make another great discovery, or went in the wrong direction. This review analyzes such missed opportunities focusing on macromolecular crystallographers (using Perutz, Pauling, Franklin as examples), although cases of particular historical (Kepler), methodological (Laue, Patterson) or structural (Pauling, Ramachandran) relevance are also described. Linus Pauling, in particular, is presented several times in different circumstances, as a man of vision, oversight, or even blindness. His example underscores the simple truth that also in science incessant creativity is inevitably connected with some probability of fault. Published 2014. This article is a U.S. Government work and is in the public domain in the USA.

  3. BAT-BORNE RABIES IN LATIN AMERICA

    Directory of Open Access Journals (Sweden)

    Luis E. Escobar

    2015-02-01

    Full Text Available The situation of rabies in America is complex: rabies in dogs has decreased dramatically, but bats are increasingly recognized as natural reservoirs of other rabies variants. Here, bat species known to be rabies-positive with different antigenic variants, are summarized in relation to bat conservation status across Latin America. Rabies virus is widespread in Latin American bat species, 22.5%75 of bat species have been confirmed as rabies-positive. Most bat species found rabies positive are classified by the International Union for Conservation of Nature as “Least Concern”. According to diet type, insectivorous bats had the most species known as rabies reservoirs, while in proportion hematophagous bats were the most important. Research at coarse spatial scales must strive to understand rabies ecology; basic information on distribution and population dynamics of many Latin American and Caribbean bat species is needed; and detailed information on effects of landscape change in driving bat-borne rabies outbreaks remains unassessed. Finally, integrated approaches including public health, ecology, and conservation biology are needed to understand and prevent emergent diseases in bats.

  4. Obesogenic environment – intervention opportunities

    Full Text Available ABSTRACT Objectives: To evaluate environmental obesogenic-related factors, such as physical activity in neighborhoods and schools, nutritional behavior, and intervention programs. Sources: Critical analysis of literature with personal point of view from infant obesity experts and political advisors for public intervention. Data synthesis: Although obesity is a public health problem affecting several age groups, it is among children and adolescents that it plays a more important role, due to treatment complexity, high likelihood of persistence into adulthood, and association with other non- transmissible diseases while still in early age. Environment is a main component of the genesis and outcomes in the near future or long term. Modification of intake with high-density food, meal skipping, and high intake of saturated fat, sugar, and salt, associated to high levels of sedentarism are main causes of obesity. Conclusion: Intervention opportunities are related to modifications in political, environmental, and individual settings. School and physical activities in the educational environment are intertwined with nutrition intervention in continuous education. A critical review of some different scenarios in Latin American countries is presented.

  5. Tuberculosis diagnostics: Challenges and opportunities

    Full Text Available Tuberculosis (TB has been a disease affecting almost all parts of the world since ages. Lot many efforts came in the past for improving diagnosis and treatment. Also, an effective vaccine has been sought after for long. With the emergence of resistant strains of Mycobacterium tuberculosis, the causal organisms of tuberculosis, and complexities emerging due to other associated infections and disease conditions, there is a desperate need for further research input in the field. Be it the better medication and care or better resistance management, proper diagnostics holds the key to success. It has been observed that a high burden of the disease was accompanied by resource limitations and poor research set-up. The scenario remained like this for several decades. With the refreshed vision of resourceful countries and funding agencies, funding is being provided in many areas of research in tuberculosis diagnosis and treatment. This review has been written with an aim to bring forth the limitations of available methods in the field of diagnostics and making researchers aware about the changing scenario with better funding opportunities and support. The author visualizes an enthusiasm from all over the world for the development of better modalities and urges scientists to join the struggle at this very perfect time to take the challenge and come forward with innovations in this field.

    Full Text Available We’ve reached the end of another year of publication at EBLIP, my first at the helm as Editor‐in‐Chief, and four full years of publication since we began. This year was a busy one with several changes to the editorial team, the addition of more Editorial Advisors, and new evidence summary writers joining our team. Most importantly, the journal continues to grow and thrive, with more people than ever participating in its success. This year we added a new section called Using Evidence in Practice, and in this issue there are two articles in that section which provide practical examples of applying evidence in the workplace. Putting evidence into practice is what EBLIP is all about, so it is my hope that this new section makes the application of evidence based practice more concrete for readers. As we began working on issue 4.4, the Editorial Team decided that it would be a good idea to seek out an Editorial Intern to help with some of the tasks we never seem to get to, given that we are all volunteers. We see the internship as an opportunity to give a library and information studies student a chance to get involved with an open access journal and learn about publishing in library and information studies, which will hopefully benefit them as they begin their new career. The Editorial Intern will assist with marketing and promotion of the journal, soliciting potential manuscripts, and proofreading. They will also participate in all editorial meetings and general discussions. We anticipate that they will bring a wealth of enthusiasm and fresh ideas to our conversations so that EBLIP Editors can also continue to learn and grow by having a fresh set of eyes involved with our processes. It will certainly be a win‐win situation and a learning opportunity for all involved. We are pleased to announce that Andrea Baer has accepted the position of Editorial Intern and joined our team in mid‐November. Andrea is currently attending the University of

    ARPEL (Asistencia Reciproca Petrolera Estatal Latinoamericana -Latin America State Oil Companies Association for Mutal Assistance) is a private organization working for the benefit of its 20 member companies as well as promoting the economic integration of their respective countries. The Latin American State Oil Companies (LASOCs) are responsible for 80% of petroleum activities in the region, which in 1990 amounted to 7.4 mbd or 11.4% of the world's production. Mexico and Venezuela are responsible for 2/3 of the output. The LASOCs, besides filling domestic needs and seeking country self-sufficiency, look for opportunities for participation in international markets and to attract external investment. (authors)

    Full text: The use of nuclear technology and materials for a wide range of industrial, scientific, medical and energy purposes creates a strong need to assure the availability of relevant skills to support their safe and effective use. Whatever the expected future of nuclear power in different countries, there remains a strong need to sustain a high level of nuclear scientific and engineering expertise in order to contribute to and inform a wide variety of policymaking, safety, technological, medical, and industrial activities. The current talent-base in nuclear technology and science has been built in these countries since the 1950s. The pioneering generation is now long retired and the generation they trained during the expansion period of nuclear technology is now also approaching retirement age. While many aspects of the knowledge accumulated during the pioneering period is well preserved through scientific research reports, design documentation and other publications, and reflected in university training programs, there is greater concern about how to sustain the practical science and technology skills and expertise that can only be obtained through challenging activities such as research and advanced technology development projects. The ageing of the general workforce in the nuclear industry, declining student enrolment in science and engineering programs, and the risk of losing accumulated knowledge and experience have drawn attention to the need for better management of nuclear knowledge. Significant effort needs to be made to maintain adequate skilled workforce and attract new employees for long-term sustainability. Addressing these challenges is very difficult for all but the largest and best-funded national programs. Even for these large programs, the opportunities are fleeting and the attractiveness of research project experiences can be mixed. Working together in an international context, countries can achieve a powerful solution to this situation by

    Wind Power Activities by Country: Developers/Owners, Wind Plant Sizes, Wind Turbines Deployed, Commissioning Dates, Market Share, and Capacity Forecasts Latin American markets are a subject of intense interest from the global wind industry. Wind plant construction across Latin America is modest compared to the more established markets like the United States, Europe, and China, but it is an emerging market that is taking off at a rapid pace. The region has become the hottest alternative growth market for the wind energy industry at a time when growth rates in other markets are flat due to a variety of policy and macroeconomic challenges. Globalization is driving sustainable economic growth in most Latin American countries, resulting in greater energy demand. Wind is increasingly viewed as a valuable and essential answer to increasing electricity generation across most markets in Latin America. Strong wind resources, coupled with today's sophisticated wind turbines, are providing cost-effective generation that is competitive with fossil fuel generation. Most Latin American countries also rely heavily on hydroelectricity, which balances well with variable wind generation. Navigant Research forecasts that if most wind plants under construction with planned commissioning go online as scheduled, annual wind power installations in Latin America will grow from nearly 2.2 GW in 2013 to 4.3 GW by 2022. This Navigant Research report provides a comprehensive view of the wind energy market dynamics at play in Latin America. It offers a country-by-country analysis, outlining the key energy policies and development opportunities and barriers and identifying which companies own operational wind plants and which wind turbine vendors supplied those projects. Market forecasts for wind power installations, capacity, and market share in Latin America, segmented by country and company, extend through 2022. The report also offers an especially close analysis of Brazil and Mexico

    The vast majority of observing time on the Space Infrared Telescope Facility (SIRTF), to be launched next year, will be available to the broad science community. A unique and innovative component of this community observing time is the Legacy Science Program, enabling investigators to conduct large and coherent science programs early in the mission, with data entering the public domain immediately upon processing at the SIRTF Science Center (SSC). The Legacy Science Call for Proposals (CP) is now open, and proposals are due on September 15, 2000. The first General Observer CP will be issued in late 2001, with proposals due four months after launch. Subsequent CPs will be issued by the SSC on an approximately annual basis. Archival research with SIRTF data will be possible within 6 months of launch, utilizing data from the First-Look Survey and from early Legacy Science observations. The author will provide an overview of the research opportunities available with SIRTF, the nominal schedule of CPs, and the anticipated plans for data analysis funding. Proposal submission procedures, and an introduction to planning and proposing tools and resources, will be provided. A description of the SIRTF observing modes and their corresponding SSC pipeline data products will also be presented.

    Full Text Available Background Protected areas, regarded today as a cornerstone of nature conservation, result from an array of multiple motivations and opportunities. We explored at global and regional levels the current distribution of protected areas along biophysical, human, and biological gradients, and assessed to what extent protection has pursued (i a balanced representation of biophysical environments, (ii a set of preferred conditions (biological, spiritual, economic, or geopolitical, or (iii existing opportunities for conservation regardless of any representation or preference criteria. Methods We used histograms to describe the distribution of terrestrial protected areas along biophysical, human, and biological independent gradients and linear and non-linear regression and correlation analyses to describe the sign, shape, and strength of the relationships. We used a random forest analysis to rank the importance of different variables related to conservation preferences and opportunity drivers, and an evenness metric to quantify representativeness. Results We find that protection at a global level is primarily driven by the opportunities provided by isolation and a low population density (variable importance = 34.6 and 19.9, respectively. Preferences play a secondary role, with a bias towards tourism attractiveness and proximity to international borders (variable importance = 12.7 and 3.4, respectively.

    2015-08-19

    Malaria remains a significant public health issue in South America. Future climate change may influence the distribution of the disease, which is dependent on the distribution of those Anopheles mosquitoes competent to transmit Plasmodium falciparum. Herein, predictive niche models of the habitat suitability for P. falciparum, the current primary vector Anopheles darlingi and nine other known and/or potential vector species of the Neotropical Albitarsis Complex, were used to document the current situation and project future scenarios under climate changes in South America in 2070. To build each ecological niche model, we employed topography, climate and biome, and the currently defined distribution of P. falciparum, An. darlingi and nine species comprising the Albitarsis Complex in South America. Current and future (i.e., 2070) distributions were forecast by projecting the fitted ecological niche model onto the current environmental situation and two scenarios of simulated climate change. Statistical analyses were performed between the parasite and each vector in both the present and future scenarios to address potential vector roles in the dynamics of malaria transmission. Current distributions of malaria vector species were associated with that of P. falciparum, confirming their role in transmission, especially An. darlingi, An. marajoara and An. deaneorum. Projected climate changes included higher temperatures, lower water availability and biome modifications. Regardless of future scenarios considered, the geographic distribution of P. falciparum was exacerbated in 2070 South America, with the distribution of the pathogen covering 35-46% of the continent. As the current primary vector An. darlingi showed low tolerance for drier environments, the projected climate change would significantly reduce suitable habitat, impacting both its distribution and abundance. Conversely, climate generalist members of the Albitarsis Complex showed significant spatial and

  12. Demographic tensions in Central America.

    Science.gov (United States)

    1986-08-01

    This discussion of Central America focuses on the rapid growth of its population, its stagnating economy, and those countries that are socioeconomically advanced. Between 1950-85 the population of Central America tripled, from 9.1 million to 26. 4 million, due to marked mortality declines and the absence of off-setting fertility declines. The distribution of Central Americas's growing populations sets its population growth apart from that of other developing regions. Currently, almost half of all Central Americans live in cities. Although the average growth rate for Central American countries has fallen and is expected to drop further, the decline does not counterbalance the effect of the absolute rise in population numbers. The average annual growth rate of more than 3% annually in the 1960s fell to about 2.6% in recent years, but this decline is due primarily to socioeconomically advanced Costa Rica and Panama. Central America's age structure further complicates the population crisis. About 43% of Central Americans are under the age of 15. When the increasingly larger young population group enters it reproductive years, the potential for future growth (albeit the falling rate of population increase) is unparalleled. UN population projections show the region's population at 40 million by the year 2000. The 1973 oil crisis began a downward spiral for the buoyant post World War II Central American economy. Between 1950-79, real per capita income growth in Central America doubled, with Central American economies growing an average of 5.3% annually. By the early 1980s, overseas markets of the trade-dependent countries of Central America had dried up due to protectionism abroad and slumping basic commodity prices. These and other factors plunged Central America into its current economic malaise of falling real per capita income, rising unemployment, curtailed export led economic growth, and a rising cost of living. In general, economic growth in Central America

    1993-01-01

    This conference report of the Centro de Estudios Migratorios Latinoamericanos and the Center for Migration Studies pertains to meetings held in August 1992. Summary information on migration movements in Latin America is presented by region and subject. The topic of integration in the Americas was presented by Mr. Lelio Marmora. Other topics and presenters include the new Colombian Migration Policy (Mr. Carlos Adolfo Arenas), the integration policies in Central America (Mr. Pilar Norza of Costa Rica, Raimundo Alvarado of El Salvador, and Luis Armando Gusman of Nicaragua), the Andean Pact agreements (representatives of each country), US immigration policy (Charles B. Keely), the Mexican integration with Latin America and immigration to the US (Jorge Bustamante), migration to Bolivia and Argentina and Chile, and transnationalism in the Caribbean (Professor Andre Corten). Migration policy needs to be tailored specifically to the situation in Latin America, and greater attention needs to be devoted to labor migrants' rights and working conditions. There are still fundamental differences among countries in policies regarding the free circulation of persons across borders. There is a division among those who support migration and those who are realists. National sovereignty issues are solvable because of a common national past and a relatively homogenous population. Another opinion is that Latin America is more diverse than commonly recognized. Capital is protected more in international agreements than is migrant labor. Regional integration for the US does mean immigration from Mexico. The US sees Mexican migration as a policy problem, and Mexico sees migration as a labor opportunity.

Signs of these correlations are highly coincident with those found in the Old World. These results provide experimental support for the adaptive value of the chromosomal-inversion polymorphism...

  15. Population pressures in Latin America.

    Science.gov (United States)

    Merrick, T W; Kent, M M; Van Der Tak, J; Von Cube, A

    1986-07-01

    In 1950 Latin America's population of 165 million was on a par with the 166 million of North America. 2 decades of growth at nearly 3% a year pushed the total to 405 million in 1985, vs. 264 million in North America. Despite substantial fertility declines since the 1960s, continued growth is ensured by the demographic momentum built into the region's large and youthful population bases. UN medium projections put the 2025 total at 779 million, compared to 345 million in North America. This Bulletin examines the main demographic changes in Latin America since World War II and their links to economic and social changes in the region as well as their implications for international and social relations. The post World War II population surge was accompanied by massive rural-ruban and international migration, rapid urbanization, large labor shifts out of agriculture into industry and services, increased education for both men and women, and higher labor force participation for females. The rural exodus was spurred by extreme land tenure inequalities and the urban bias of postwar industrialization. The labor-saving bias of this industrialization forced exploding city populations to turn to the informal sector for jobs. Population pressures on city services and housing as well as jobs have been further exacerbated by overconcentration in a few large cities and economic downturns of the 1980s. Recent fertility declines seem to be the result of both increased access to family planning and the economic and social pressures posed by the gap between young adults' aspirations and their ability to realize them. Population and economic pressures could induce faster fertility declines than now projected but in the short run are likely to mean more employment problems, continued rapid urban growth, and even larger international immigration flows within the hemisphere, particularly to the US.

The problem complexity and the business environment dynamics – including an interaction with other main trends in logistics and modern supply chains – both led to a permanent literature gap, indicating the need to explore some new aspects of logistics outsourcing (LO. In this paper, a new LO research perspective has been explored by identifying some weaknesses in the main LO research streams and related common viewpoints which led to six ‘logistics outsourcing research paradoxes’. Each of these paradoxes is briefly described and their links with research streams and common views on LO discussed. Finally, the nature of some known opportunities for further research is better explained and some overlooked research opportunities are highlighted.

  20. Current Status of Engineering Education in America

    Barr, Ronald E.

    Many faculty believe that engineering education in America is at a crossroads and much change is needed. International competition in engineering and the global economy have major potential impact on the engineering workforce of the future. We must find ways to educate U.S. engineers to be competitive and creative contributors in the worldwide arena. Recent national reports are sounding the alarm that the U.S. is losing it leadership in technology and innovation, with consequences for economic prosperity and national security. The report Rising Above the Gathering Storm discusses this dilemma in detail and offers four recommendations to U.S. policymakers. The report Educating the Engineer of 2020 discusses new ways to prepare American engineers for the 21st Century. Furthermore, changes in ABET accreditation, along with new paradigms of teaching and new technology in the classroom, are changing the scholarship of engineering education. We must find ways to promote change in engineering faculty for this new opportunity in engineering educational scholarship. Future engineering students are now in K-12, which is becoming an increasingly diverse population that in the past has not been fully represented in engineering education. Current trends show disaffection for pursuing studies in science and engineering in the youth of our U.S. society. We must find new ways to portray engineering as an exciting and rewarding career, and certainly as an educational platform for professional careers beyond the baccalaureate degree.

    The Wind Powering America FY07 Activities Summary reflects the accomplishments of our state wind working groups, our programs at the National Renewable Energy Laboratory, and our partner organizations. The national WPA team remains a leading force for moving wind energy forward in the United States. WPA continues to work with its national, regional, and state partners to communicate the opportunities and benefits of wind energy to a diverse set of stakeholders. WPA now has 30 state wind working groups (welcoming Georgia and Wisconsin in 2007) that form strategic alliances to communicate wind's benefits to the state stakeholders. More than 140 members of national and state public and private sector organizations from 39 U.S. states and Canada attended the 6th Annual WPA All-States Summit in Los Angeles in June. WPA's emphasis remains on the rural agricultural sector, which stands to reap the significant economic development benefits of wind energy development. Additionally, WPA continues its program of outreach, education, and technical assistance to Native American communities, public power entities, and regulatory and legislative bodies.

  2. Irrigation Water Management in Latin America

    2009-12-01

    Full Text Available Latin American countries show a great potential for expanding their irrigated areas. Irrigation is important for strengthening local and regional economy and for enhancing food security. The present paper aimed at providing a brief review on key aspects of irrigation management in Latin America. Poor irrigation management can have great impact on crop production and on environment while good management reduces the waste of soil and water and help farmers maximizing their profits. It was found that additional research is needed to allow a better understanding of crop water requirements under Latin American conditions as well as to provide farmers with local derived information for irrigation scheduling. The advantages of deficit irrigation practices and the present and future opportunities with the application of remote sensing tools for water management were also considered. It is clear that due to the importance of irrigated agriculture, collaborative work among Latin American researchers and institutions is of paramount importance to face the challenges imposed by a growing population, environment degradation, and competition in the global market.

  3. From Ideas to Opportunities: Exploring the Construction of Technology-Based Entrepreneurial Opportunities

    Directory of Open Access Journals (Sweden)

    2013-06-01

    Full Text Available The transformation of business ideas into market opportunities is at the core of entrepreneurship. Nevertheless, the complexity of such a transformative process is seen to change depending on the variables influencing the opportunity-entrepreneur nexus. Although technology-entrepreneurship is regarded as a force of change and dynamism in socio-economic growth, it also depends upon an intricate process of opportunity development. The interest in understanding better how technology-based entrepreneurs simultaneously cope with technological uncertainty while trying to gain stakeholder support and access to resources, highlights a relevant research gap. The research described in this article uses the constructivist view to deepen our understanding of the technology-based entrepreneur’s conceptualization of the opportunity as a process of social construction. Our results show how initial consensus-building efforts and iteration with knowledgeable peers are an essential part of the emergence of the opportunity, changing both entrepreneur's and stakeholders' perceptions of the early business idea. Consequently, our results provide evidence in support of policy programs and measures that favour social-construction support mechanisms to foster technology-based entrepreneurship.

    Recent developments in digital technologies and the rise of the Internet have created new opportunities for citizen science. One of these has been the development of online citizen science games where complex research problems have been re-imagined as online multiplayer computer games. Some of the most successful examples of these can be found within the biological sciences, for example, Foldit, Phylo and EteRNA. These games offer scientists the opportunity to crowdsource research problems, and to engage with those outside the research community. Games also enable those without a background in science to make a valid contribution to research, and may also offer opportunities for informal science learning.

    Phosphorus (P) is one of the essential nutrients for plants, and is indispensable for plant growth and development. P deficiency severely limits crop yield, and regular fertilizer applications are required to obtain high yields and to prevent soil degradation. To access P from the soil, plants have evolved high- and low-affinity Pi transporters and the ability to induce root architectural changes to forage P. Also, adjustments of numerous cellular processes are triggered by the P starvation response, a tightly regulated process in plants. With the increasing demand for food as a result of a growing population, the demand for P fertilizer is steadily increasing. Given the high costs of fertilizers and in light of the fact that phosphate rock, the source of P fertilizer, is a finite natural resource, there is a need to enhance P fertilizer use efficiency in agricultural systems and to develop plants with enhanced Pi uptake and internal P-use efficiency (PUE). In this review we will provide an overview of continuing relevant research and highlight different approaches towards developing crops with enhanced PUE. In this context, we will summarize our current understanding of root responses to low phosphorus conditions and will emphasize the importance of combining PUE with tolerance of other stresses, such as aluminum toxicity. Of the many genes associated with Pi deficiency, this review will focus on those that hold promise or are already at an advanced stage of testing (OsPSTOL1, AVP1, PHO1 and OsPHT1;6). Finally, an update is provided on the progress made exploring alternative technologies, such as phosphite fertilizer. © 2016 The Authors The Plant Journal © 2016 John Wiley & Sons Ltd.

    Directory of Open Access Journals (Sweden)

    Robert G. Bednarik

    2014-04-01

    Full Text Available In contrast to the great time depth of Pleistocene rock art and mobiliary ‘art’ in the four other continents, the available evidence from the Americas is very limited, and restricted at best to the last part of the final Pleistocene. A review of what has so far become available is hampered by a considerable burden of literature presenting material contended to be of the Ice Age, even of the Mesozoic in some cases, that needs to be sifted through to find a minute number of credible claims. Even the timing of the first colonization of the Americas remains unresolved, and the lack of clear-cut substantiation of palaeoart finds predating about 12,000 years bp is conspicuous. There are vague hints of earlier human presence, rendering it likely that archaeology has failed to define its manifestations adequately, and Pleistocene palaeoart remains almost unexplored at this stage.

    2004-11-01

    Robert Kovach's second book looks at the interplay of earthquake and volcanic events, archeology, and history in the Americas. Throughout history, major earthquakes have caused the deaths of millions of people and have damaged countless cities. Earthquakes undoubtedly damaged prehistoric cities in the Americas, and evidence of these events could be preserved in archeological records. Kovach asks, Did indigenous native cultures-Indians of the Pacific Northwest, Aztecs, Mayas, and Incas-document their natural history? Some events have been explicitly documented, for example, in Mayan codices, but many may have been recorded as myth and legend. Kovach's discussions of how early cultures dealt with fearful events such as earthquakes and volcanic eruptions are colorful, informative, and entertaining, and include, for example, a depiction of how the Maya would talk to maize plants in their fields during earthquakes to reassure them.

    International Nuclear Information System (INIS)

    Kielmas, M.

    1994-01-01

    In the early 1990s Latin America became a favoured target for foreign investors as one of the side-effects of the collapse of communism in Eastern Europe and the Soviet Union. The reason is linked to macroeconomic reforms in Latin America and the failure of equivalent reforms in the former communist countries. Latin American state-owned-oil companies have been welcomed as borrowers on the international financial markets. Simultaneously private sector investment in the oil industry has increased. This chapter examines nationalisation and the state oil companies, the financing of the state sector, privatisation, the boosting of oil exploration and security issues. The sustainability of the economic reforms in the region is discussed. (UK)

  19. Remittances in Central America: Whose Money is it Anyway?

    Directory of Open Access Journals (Sweden)

    Jose Luis Rocha

    2015-08-01

    Full Text Available In opposition to optimistic visions that present remittances as an opportunity for developing countries, this paper shows they are part and parcel of a process of economic imperialism, whereby their use and final destinations are strictly conditioned. In order to go beyond a conception of remittances as epiphenomenon, and in order to trace the role they play, this paper focuses on the transnational strategies of capital. It finds that remittances enable an increase in foreign investment and import production by facilitating the rise of a new class of consumers in Central America. Remittances create and feed a purchasing power that would not exist in their absence. Factories, fast food restaurants, communications companies, banks, travel agencies, and supermarkets are opening new branches throughout Central America in order to benefit from transnational savings that would otherwise be used differently. In this way, remittances are conditioned and co-opted by transnational capital’s strategies to sustain an ever growing market, with Central America more generally – and once again – potentially at risk of becoming characterized by enclave economies and chronic commercial deficits. The remittance-based economic model furthermore cannot be sustainable in the long run unless Central American countries keep exporting workers ad infinitum, something that is obviously not possible.

The general goals of this programme, which was part of the ARCAL (Arreglos Regionales Cooperativos para la promocion de la ciencia y la tecnologia nucleares en America Latina) project, were to characterize and improve the reproductive management of milk, meat and fibre producing livestock maintained under the diverse environmental and management conditions prevailing in the Latin America region. In particular, the programme addressed the efficacy of using radioimmunoassay methods of measuring reproductive performance based on breeding and production records, behaviour and clinical parameters. One of the major achievements of the programme was the establishment of viable RIA laboratories in each of the participant countries

  9. Natural gas in Latin America

    International Nuclear Information System (INIS)

    1997-01-01

    Despite having proven reserves equal to that of North America, natural gas has traditionally played a minor role in the energy policies of Latin American countries, being considered secondary to oil. There has, therefore, been a neglect of the sector with a resultant lack of an adequate infrastructure throughout the region, perhaps with the exception of Argentina. However, with a massive increase in energy demand, growing concerns with environmental matters and a need to reduce the massive pollution levels in major cities in the region, natural gas is forecast to play a much greater role in Latin America's energy profile, with final consumption forecast to rise at 5.4% per annum for the next 15 years. This book assesses both the development of the use of natural gas in the power industrial sector and proposals for its growth into the residential, commercial and transport sectors. It analyses the significant investment required and the governments' need to turn to the private sector for investment and innovation. Natural Gas in Latin America analyses the possibilities and pitfalls of investing in the sector and describes the key trends and issues. It analyses all aspects of the gas industry from exploration and production to transportation and distribution to end users. (Author)

One of them is the implementation of The Lisbon Strategy aiming at the worlds most dynamic and competitive knowledge– based economy by 2010. Under the strategy, a stronger economy will drive job creation, sustainable development, and social inclusion. These changes demand the modernisation of education systems in the E U states, Lithuania among them. To achieve this objective, political forces came to an agreement on the future of Lithuanian education. In 2003 The Seimas of the Republic of Lithuania approved of National Education Strategy 2003–2012. This strategy is special not only because it is based on the experiences of the reform, addresses current and future world’s challenges and opportunities, maintains links with other strategic national reforms, but also emphasises efforts to ensure quality lifelong education for Lithuanian population and striving to become a partner in modern knowledge-based economy. Therefore, an extensive discussion on lifelong education strategies on individual and institution levels in all spheres of social and personal life has started in the E U and Lithuania. Nowadays lifelong learning is not just one aspect of education and training; it gradually is becoming the most important principle in the continuum of complex learning contexts. Such vision must be implemented this decade. The object of the research: the preconditions for the development of continuing adult education. The aim of the research: to examine the peculiarities of the preconditions for the development of continuing adult education in Pakruojis region. The methods of the research: analysis of references and documents on education; an anonymous survey in written form (a questionnaire; statistical analysis of data. The sample.

  13. The Paradox of Equal Opportunities

    Directory of Open Access Journals (Sweden)

    Mitja Sardoč

    2014-06-01

    Full Text Available The basic assumption of the idea of equal opportunities is based on the assertion that all individuals competing for an advantaged social position should have equal opportunities, i.e., that each and every one of them should have fair opportunities to achieve a particular goal. Despite the fact that equal opportunities is one of the basic mechanisms for a just distribution of advantageous social positions, the idea of fair equality of opportunity remains divided between different competing political projects, e.g., egalitarian liberalism, libertarian political theory, multiculturalism, etc. This paper examines two basic dimensions of equal opportunities to which existing conceptions fail to offer a unanimous answer, i.e., a the issue of fairness and b the issue of the currency of fairness. The concluding part of this paper presents two basic paradoxes that determine both the direction of the discussion as well as the possible solutions to the achievement of fair equal opportunities as part of any process for competing for advantageous social positions.

    2009-03-23

    The role of mathematics in a complex system such as the Internet has yet to be deeply explored. In this paper, we summarize some of the important and pressing problems in cyber security from the viewpoint of open science environments. We start by posing the question 'What fundamental problems exist within cyber security research that can be helped by advanced mathematics and statistics'? Our first and most important assumption is that access to real-world data is necessary to understand large and complex systems like the Internet. Our second assumption is that many proposed cyber security solutions could critically damage both the openness and the productivity of scientific research. After examining a range of cyber security problems, we come to the conclusion that the field of cyber security poses a rich set of new and exciting research opportunities for the mathematical and statistical sciences.

  16. Gauging gas sector opportunities in Asia

    International Nuclear Information System (INIS)

    Cox, L.C.

    1996-01-01

    The future prospects for use of liquefied natural gas in Asia were examined, combined with a description of the opportunities and risks of investing in the Asian energy sector. It was concluded that the marked increase in energy demand makes market development for natural gas in Asia similar to what it was in North America several decades ago. Rapid economic development has increased the value of electricity, and natural gas is seen as the ideal fuel to generate it, as well as helping to combat local air pollution. Some of the barriers to expanded natural gas use include structural problems resulting from government action (or inaction), lack of an efficient distribution system and stable pricing for natural gas. Nevertheless, interest is growing, and however slowly, progress is inevitable At the same time, it should be emphasized that while the prospects are good for the domestic gas sector, there is yet no country where a foreign firm has been permitted to bring natural gas into the country, either by pipeline, or as liquid natural gas. 7 figs

  3. Growing pains in South America.

    Science.gov (United States)

    Joyce, S

    1997-08-01

    This article describes some negative effects from modernization and urban growth in South America, including disease, pesticides, occupational hazards, poor environmental controls of water and garbage, sanitation, and environmental degradation. South America is following the global trend toward urbanization and the problems that accompany it. Agricultural expansion led to an expanded market for pesticides that includes the deadly DDT, paraquat, and heptachlor. Brazil and Colombia are the largest consumers. Latin American officials justify use of DDT, which is banned in the US and many European countries, as an effective means of combating mosquitos that carry malaria. Exposure occurs during harvesting, transporting, forestry, livestock farming, and vector control activities. Methyl bromide, which is used post-harvest and as a soil fumigant, is dangerous enough to be banned in the US in 2001, and in developing countries in 2002. Exposure to toxic chemicals can severely inhibit enzyme action that is necessary for neurological functioning. A hot climate, which prevents protective clothing, lack of education on proper application, and absence of water to wash exposed skin, make pesticide protection very difficult. Over 40 million agricultural workers are at risk of pesticide poisoning. Habitat destruction has contributed to increased mosquito infestations. Children in the workplace are at even greater risk of noise pollution and chemical poisoning. South America pollutes almost 11 times more fresh water per capita than Europe. About 70% of domestic garbage is collected, and about 30% is disposed of correctly. Only 10% of urban wastewater is treated before discharge into waterways. The loss of coastal wetlands reduces the ability of waterways to filter and absorb nutrients. Environmental health problems suggest an interlinkage between environmental sustainability, human health, and economic growth.

  4. Research Opportunities in Space Propulsion

    Science.gov (United States)

    Rodgers, Stephen L.

    2007-01-01

    Rocket propulsion determines the primary characteristics of any space vehicle; how fast and far it can go, its lifetime, and its capabilities. It is the primary factor in safety and reliability and the biggest cost driver. The extremes of heat and pressure produced by propulsion systems push the limits of materials used for manufacturing. Space travel is very unforgiving with little room for errors, and so many things can go wrong with these very complex systems. So we have to plan for failure and that makes it costly. But what is more exciting than the roar of a rocket blasting into space? By its nature the propulsion world is conservative. The stakes are so high at every launch, in terms of payload value or in human life, that to introduce new components to a working, qualified system is extremely difficult and costly. Every launch counts and no risks are tolerated, which leads to the space world's version of Catch-22:"You can't fly till you flown." The last big 'game changer' in propulsion was the use of liquid hydrogen as a fuel. No new breakthrough, low cost access to space system will be developed without new efficient propulsion systems. Because there is no large commercial market driving investment in propulsion, what propulsion research is done is sponsored by government funding agencies. A further difficulty in propulsion technology development is that there are so few new systems flying. There is little opportunity to evolve propulsion technologies and to update existing systems with results coming out of research as there is in, for example, the auto industry. The biggest hurdle to space exploration is getting off the ground. The launch phase will consume most of the energy required for any foreseeable space exploration mission. The fundamental physical energy requirements of escaping earth's gravity make it difficult. It takes 60,000 kJ to put a kilogram into an escape orbit. The vast majority (-97%) of the energy produced by a launch vehicle is used

    Present energy consumption patterns, known reserves of conventional energy sources (oil, gas, coal, and hydroelectricity), and the impact of the oil crisis on the oil-importing countries of Latin America are discussed. New approaches to energy use, including improvements on end-use efficiency, fuel substitutions, nonconventional energy sources, and changes in consumption patterns, are important. Of particular significance are the alcohol program in Brazil and the possibilities for increased use of hydroelectricity. Investments needed to sustain a reasonable increase in production from conventional energy sources up to 1990 are presented.

  10. Wind energy developments in the Americas

    International Nuclear Information System (INIS)

    Swisher, R.; Ancona, D.F.

    1990-01-01

    This paper will highlight the key wind energy activities and programs of American countries. In South and Central America, wind technology awareness and opportunity is spreading. Countries have projects in the beginning stages of development and many sites with excellent wind resources are believed to exist. Argentina, Costa Rica, Colombia, Mexico, and several Caribbean countries are among those active in wind energy development. In Canada, after a decade of research and systems development, the Department of Energy Mines and Resources is conducting a review of all renewable energy technologies, including wind, to develop a strategic plan for future activities. Canadian industry continues development of various vertical axis projects and the Province of Alberta has begun a program to assess wind potential in that region. In the United States, commercial application of wind energy is continuing to expand. During 1989, over 140 MW of new wind turbine capacity was installed in wind power plants, bringing the total operating in the U.S. to 14600 turbines and 1,400 MW. During 1989, these machines produced over 2.1 billion kWh, enough to supply the residential needs of Washington D.C. or San Francisco. This is an increase of 15% over the 1988 total, even though installed operating capacity dropped by about 10% as smaller, out-dated turbines were phased out or replaced. The U.S. government is in the process of formulating a new National Energy Strategy. It seems clear that renewable energy and energy efficiency will play an increasingly important role in this strategy. The U.S. wind program continues to emphasize broad-based technology development, but has also initiated conceptual design studies for an advanced wind turbine for power generation in the late 1990s.

    2002-05-16

    To support the North American Energy Working Group's Expert Group on Energy Efficiency (NAEWG-EE), USDOE commissioned the Collaborative Labeling and Appliance Standards Program (CLASP) to prepare a resource document comparing current standards, labels, and test procedure regulations in Canada, Mexico, and the United States. The resulting document reached the following conclusions: Out of 24 energy-using products for which at least one of the three countries has energy efficiency regulations, three products -- refrigerators/freezers, split system central air conditioners, and room air conditioners -- have similar or identical minimum energy performance standards (MEPS) in the three countries. These same three products, as well as three-phase motors, have similar or identical test procedures throughout the region. There are 10 products with different MEPS and test procedures, but which have the short-term potential to develop common test procedures, MEPS, and/or labels. Three other noteworthy areas where possible energy efficiency initiatives have potential for harmonization are standby losses, uniform endorsement labels, and a new standard or label on windows. This paper explains these conclusions and presents the underlying comparative data.

  16. Scale is not an Issue : Opportunities for Collaboration among Geoscientists in Latin America and the Caribbean

    Science.gov (United States)

    Carby, B. E.

    2015-12-01

    Latin American and Caribbean (LAC) countries face multiple hazards such as earthquakes, volcanoes, accelerated erosion, landslides, drought, flooding, windstorms and the effects of climate variability and change. World Bank (2005) data indicate that seventeen of the top thirty-five countries with relatively high mortality risk from 3 or more hazards are located in LAC, El Salvador has the second highest per cent of its population at risk - 77.7% and 7 of the top 10 countries for population exposure to multiple hazards are in LAC. All LAC countries have half or more of GDP exposed to at least one hazard. The report underscores the need for better data and information on hazards and disasters to inform disaster risk reduction (DRR) and supports the view that reduction of disaster risk is essential for achieving Sustainable Development (SD). This suggests that DRR must be integrated into development planning of countries. However the Global Assessment Report notes that globally, there has been little progress in mainstreaming DRR in national development (UNISDR 2009). Without this, countries will not realise development goals. DRR efforts in LAC require an integrated approach including societal input in deciding priority DRR research themes and interdisciplinary, multi-hazard research informing DRR policy and practice. Jiminez (2015) from a study of countries across LAC reports that efforts are being made to link research to national planning through inclusion of policy makers in some university-led research projects. Research by the author in Jamaica reveals that the public sector has started to apply research on hazards to inform DRR policy, programmes and plans. As most research is done by universities, there is collaboration between the public sector and academia. Despite differences in scale among countries across the region, similarities in exposure to multiple hazards and potential hazard impacts suggest that collaboration among researchers in LAC could be beneficial. It is proposed here that this collaboration should go beyond the scientific community and should include sharing of experiences in linking DRR research to national development needs, inclusion of policy makers in research design and implementation and integration of research results in policy and programme development.

  19. Potential Opportunities for Investment in Space Technologies in Latin-America: a Case for Mexico

    Science.gov (United States)

    Sanchez, G.

    2002-01-01

    Student, Master of Space Studies. International Space University. Strasbourg Central The objective of this paper is to analyze the possible commercial benefits that the global manufacturing space industry could obtain by investing in Latin-American countries. Spacecraft manufacturers have recently been complaining about small margins. They claim that customers demand technological advancement at the same time as they push for quick delivery and competitive prices. They also argue that operators (their main customers) do have great profits. Thus, manufacturers would like to raise the prices of their spacecraft (SpaceNews. January 7, 2002. P.17). This may sound logical, but it would be interesting to analyze if the industry could find alternative ways of saving money while remaining competitive. Mexico is a good example of a Latin-American country that has received foreign investment for establishing manufacturing and assembly plants for different industries. This has been mainly due to two special characteristics of the Mexican manufacturing workforce: low labor costs and qualified, reliable human resources. As a result, Mexican manufacturing industry has acquired a solid reputation worldwide. A similar story can be told about other industries such as electronics, computer assembly, clothes, etc. It is probably worth to make an analogy with a labor-demanding industry that already has experience in the Mexican market: the car industry has found a formula to keep manufacturing costs low while maintaining production and quality levels. Mexico currently manufactures and assembles cars for European, Japanese and American companies for the international market. If the same success story could be repeated for the spacecraft manufacturing industry, the benefits would be enormous. Manufacturers could consider relocating their plants to Mexico to manufacture and test parts or entire spacecraft. This would help reduce the cost of human labor, especially because of the long periods of time required for manufacturing, assembling and testing. Evidently, such and endeavor requires a successful transfer of technology as well as many other considerations. In 1997 Mexico signed a Free Trade Agreement with the European Union and in 2000 a similar agreement with Israel. As of today, Mexico has trade agreements with USA, Canada, and many Latin-American countries. Additionally, some important companies of the aerospace industry met recently in Monterrey, Mexico with the purpose of evaluating whether investment in manufacturing plants for aircraft parts was feasible. A logical judgement indicates that the high rates that have to be paid to US workers and the small tax restrictions in the commercial activities between the two countries make it very attractive to start such operations in Mexico. Although USA and Canada could be, apparently, the most benefited countries with spacecraft assembly and manufacturing outside their territories, it will also make sense for many European countries if low transportation costs are obtainable. On the other hand, there are a number of factors to consider before attempting serious investment. Just to name a few, the transfer of sensitive technologies, security of the long-term investments, potential local investors, political issues, legal considerations, etc; are topics that have to be taken into account by interested enterprises. This paper analyzes most of these topics trying to derive a broad scenario for potential investors, and to serve as the frame of a future business plan.

  1. NGL markets in North America: 1999--2005 competitive threats and opportunities

    Lippe, D.

    1999-01-01

    Gas processing contracts are structured in two basic ways. Gas plants are typically operated on a strict margin basis, on a percentage-of-proceeds basis, or on a keep-whole basis. Based on straight margins, percentage-of-proceeds or keep-whole contracts, gas processing profitability was weaker in 1998, than at any time during the past 10 years. No matter how gas processing profitability was measured, 1998 was the worst year in the history of gas processing since 1985. The economic disaster of 1998 prompted many gas plant operators to reevaluate their long-term participation in the industry. This paper reviews the root causes that resulted in the gas processing industry's economic meltdown in 1998. Trends in crude oil prices and natural gas prices determine the fundamental profitability for gas processing. Trends in ethylene production and ethylene industry profit margins determine the levels of demand for ethane and propane. This paper also highlights the prospects for recovery in profit margins, improvement in per gallon values and the potential for growth in total demand NGL and production

    Recently in Latin America, there has been a strong influence of the "Spanish model" of organ procurement. In 2001, The "Punta Cana Group" was created by Latin American transplantation coordinators with the objective of registering and improving the system of donation and procurement. In many countries there is no universal financial support from the government for medical treatment, including dialysis and transplantation. In other countries there is complete financial support for all of the population, including immunosuppressive drugs. Practically all countries have transplantation laws that follow ethical concepts, such as brain death diagnosis criteria, forms of consent, criteria of allocation, and inhibition of commerce. The rate of potential donors notified in countries that perform transplantations with deceased donors varied from 6 to 47 per million population yearly (pmp/y); The rate of effective donors varied from 1 to 20 pmp. In 2004, the mean rate of effective donors in Latin America was 5.4 pmp. The family refusal rate for the donation of organs varied from 28% in Uruguay to 70% in Peru. In some countries, such as Puerto Rico, Uruguay, and Cuba, it was more than 15 pmp, whereas in others countries deceased donors were practically not used. The number of patients on the waiting list for solid organ transplants in 12 Latin American countries is 55,000. Although the donation rate has increased by 100% during the last 10 years, it is lower than that in Europe (15 pmm/y) or the United States (20 pmp/y).

  4. Atomic energy in Latin America

    International Nuclear Information System (INIS)

    1967-01-01

    Most countries in Latin America, including all those on the mainland, are Members of the Agency. Interest in the possibilities of nuclear energy has led to considerable activity, much of it in direct collaboration with the IAEA. Member States in the region are: Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Cuba, Dominican Republic, Ecuador, El Salvador, Guatemala, Haiti, Honduras, Jamaica, Mexico, Nicaragua, Panama, Paraguay, Peru, Uruguay, Venezuela. Of these, Argentina, Brazil, Colombia and Venezuela are operating, and Mexico and Uruguay are constructing, research reactors, while Chile and Peru are studying proposals. Argentina, Brazil, Mexico and Uruguay have all agreed to accept Agency safeguards for reactors. The possibility of future needs for nuclear power is under examination by several countries, in some cases being related to desalination of water. All atomic work in Latin America is devoted to peaceful uses, and note-worthy progress has been made with proposals for a treaty which would make the whole region a militarily de-nuclearized zone. It is proposed that when this comes into effect the Agency will be asked to apply the controls developed in its safeguards system, and to carry out the inspections necessary to establish that work in progress is solely for peaceful purposes

    Childhood obesity rates in Latin America are among the highest in the world. This paper examines and evaluates the many efforts underway in the region to reduce and prevent further increases in obesity, identifies and discusses unique research challenges and opportunities in Latin America, and proposes a research agenda in Latin America for the prevention of childhood obesity and concomitant non-communicable diseases. Identified research gaps include biological challenges to healthy growth across the life cycle, diet and physical activity dynamics, community interventions promoting healthy child growth, and rigorous evaluation of national food and activity programs and regulatory actions. Addressing these research gaps is critical to advance the evidence-based policy and practice in childhood obesity tailored to the Latin American context that will be effective in addressing obesity. © 2017 The Authors.

    Kaye, Jack A.; Canziani, Pablo; Kirchhoff, Volker W. J. H.; Proffitt, Michael; Wilcox, Bradford

    A clear recognition of the unique role that Latin America plays in the global environment was one of several major themes to emerge at a recent workshop on distributions of ozone and UVB radiation over Latin America. The region covers a very broad latitude range and has a major influence on the atmospheric circulation of the southern hemisphere. The Andes Mountains, which cover a latitudinal range of more than 60° and are from 2 o 7 km in altitude, are unique not o nly because they force gravity waves, but also because of the opportunity they provide for satellite instruments to differentiate between columns of air over high mountains and nearby sea level. Appreciable emissions of trace gases and particles from both natural and human activity in Latin America have important effects on both regional and global scales.

    Morse, W A

    1992-01-01

    The varied career opportunities open to clinical engineers are described in this paper. Many of these opportunities are within the medical device industry in research, development, manufacturing design, regulatory activities, production, operations, sales, marketing, service, and management. Additional opportunities are available in hospitals, with the Veterans Administration, or working as an entrepreneur or a consultant. Each of these careers requires specific training and skills, and they all require a fundamental scientific knowledge of physical principles and mathematics. Research and management, however, require different educational preparation. The research emphasis should be on theoretical principles and creativity; the management emphasis should be on financial and labor problems. In all clinical engineering careers, the individual is a problem solver.

    International Nuclear Information System (INIS)

    1959-01-01

    Early 1958 the Brazilian representative on the Board of Governors of the International Atomic Energy Agency - supported by the Governors from Argentina and Guatemala -proposed that a study should be made of the possibility of setting up one or more atomic energy training centres in Latin America. On the Board's recommendation, the Director General of the Agency appointed a fact-finding team to make anon-the-spot study. In drafting this report the team was invited to consider the following points: (a) The need for establishing one or more regional training centres; (b) Existing facilities that are being or could be used for training, together with technical data concerning them; (c) The general scientific technological and industrial conditions of the countries visited insofar as they have a bearing on their training needs and capabilities. The authors of the report conclude that 'a training centre in radio-botany should provide vitally needed knowledge and vitally needed specialists to all the agricultural installations in Latin America. A training centre like this might provide an excellent model upon which to base training centres in other areas'. The report recommends that: 1. The Agency should meet the requests of Latin American universities by, for example, supplying equipment and sending experts; 2. At least one specialized training centre should be established as soon as possible. Taking as an example the field of radio-botany, such a centre would provide trained specialists in radio-botany to agricultural institutions throughout Latin America and also provide basic research results vital to agriculture. The cost of new facilities might be of the order of $7 500 000, with an annual budget of approximately $650 000. Staff required: 40 scientists and 175 employees; 3. Whenever it appears feasible to gather necessary staff of high creative ability and established productivity and when funds can be made available for facilities, equipment and operating costs, at

  3. Migration patterns in Central America seen in the context of economic integration and the need for sustainable development.

    Science.gov (United States)

    Stein, E

    1993-08-01

    This exploratory discussion of migration policy in Central America focuses on actual procedures in a multisectoral framework that assumes economic integration and sustainable development. The article follows the following format: the author's perspective and general approach to the problems of migration policy and integrated development, an analysis and review of the inadequacies of concepts and methodologies and the need for strengthening Central America's policies, arguments for changing present development strategies, and suggestions for regional economic integration. New policies must be equitable, sustainable, and suitable for agricultural frontier areas at the present level of economic integration. The further development of practical and concrete solutions in the region is based on the current groundwork. New policies should emphasize community participation, a grassroots approach rather than a top-down one, and an alternative model. An alternative system which promotes and facilitates the vertical development of small and medium farmers needs both a Rural Communal Financing System and a System for Communal Marketing to eliminate all speculative economic practices which impede small farmers from making a profit. Buffer zones in the frontier agricultural areas are required. Small farms need to gradually improve farming practices rather than to transfer miraculous technologies. A number of forest products could be collected and commercialized for various purposes, if the knowledgeable indigenous population is informed and involved in participatory research on the technical and ethnological culture and action programs. Many sectors are involved, problems are complex, and the speed of change is very rapid in the region. An approach that seeks to relate sustainable development, economic integration, and migration policy must incorporate the perspective of integrated development and a structural analysis of poverty. The approach suggested in this article would

  4. Antifungal pharmacodynamics: Latin America's perspective.

    Gonzalez, Javier M; Rodriguez, Carlos A; Agudelo, Maria; Zuluaga, Andres F; Vesga, Omar

    The current increment of invasive fungal infections and the availability of new broad-spectrum antifungal agents has increased the use of these agents by non-expert practitioners, without an impact on mortality. To improve efficacy while minimizing prescription errors and to reduce the high monetary cost to the health systems, the principles of pharmacokinetics (PK) and pharmacodynamics (PD) are necessary. A systematic review of the PD of antifungals agents was performed aiming at the practicing physician without expertise in this field. The initial section of this review focuses on the general concepts of antimicrobial PD. In vitro studies, fungal susceptibility and antifungal serum concentrations are related with different doses and dosing schedules, determining the PD indices and the magnitude required to obtain a specific outcome. Herein the PD of the most used antifungal drug classes in Latin America (polyenes, azoles, and echinocandins) is discussed. Copyright © 2016 Sociedade Brasileira de Infectologia.

    2009-01-01

    This article investigates the development of nanotechnology in Latin America with a particular focus on Argentina, Brazil, Chile, and Uruguay. Based on data for nanotechnology research publications and patents and suggesting a framework for analyzing the development of R and D networks, we identify three potential strategies of nanotechnology research collaboration. Then, we seek to identify the balance of emphasis upon each of the three strategies by mapping the current research profile of those four countries. In general, we find that they are implementing policies and programs to develop nanotechnologies but differ in their collaboration strategies, institutional involvement, and level of development. On the other hand, we find that they coincide in having a modest industry participation in research and a low level of commercialization of nanotechnologies.

  8. Convergence Patterns in Latin America

    DEFF Research Database (Denmark)

    Quiroga, Paola Andrea Barrientos

    Literature on convergence among Latin American countries is still scarce compared to other regions. Moreover, almost none of the research connects convergence to the economic history of Latin America and the usual finding is one speed of convergence. In this paper I analyze 32 countries and 108...... years, more observations than any other study. This long span of data allows me to use economic history to explain, analyze, validate, and understand the results of convergence patterns in the region. I find more than one speed of convergence (clubs) related to the known historical background, country...... characteristics, and external shocks in the region. I study three important phases, following Thorp (1998): from 1900 to 1930, the exporting phase, from 1931 to 1974, the industrialization phase, and from 1975 to 2007, the globalization phase. During the last two phases, I find strong evidence of convergence...

  9. Fermilab-Latin America collaboration

    International Nuclear Information System (INIS)

    Rubinstein, R.

    1994-01-01

    Fermilab's program of collaboration with Latin America was initiated by then-Director Leon Lederman about 1980. His goal was to aid Latin American physics, and particularly its particle physics; this latter aim is in keeping with the Laboratory's particle physics mission. The reasons for collaboration between institutions in the US and Latin America are many, including geographic and cultural, together with the existence of many talented scientists and many centers of excellence in the region. There are also broader reasons; for example, it has been stated frequently that physics is the basis of much technology, and advanced technology is a necessity for a country's development. There is nothing unique about Fermilab's program; other US institutions can carry out similar activities, and some have carried out individual items in the past. On the Latin American side, such collaboration enables institutions there to carry out forefront physics research, and also to have the advantages of particle physics spin-offs, both in expertise in related technologies and in scientist training. In addition to particle physics, collaboration is possible in many other related areas. Although particle physics is frequently viewed as open-quotes big scienceclose quotes, all of the large research groups in the field are composed of many small university groups, each of which contributes to the experiment, the analysis and the physics. Fermilab is an international laboratory, open to all users; a research proposal is accepted on scientific merit and technical competence, not on the country of origin of the scientists making the proposal. Currently, of Fermilab's approximately 1400 users, about 30% are from non-US institutions. It should be noted here that Fermilab's funds, which come from the US government, are for particle physics only; however, there is some flexibility in interpretation of this

  10. Multiple identities in social perception and interaction: challenges and opportunities.

    Science.gov (United States)

    Kang, Sonia K; Bodenhausen, Galen V

    2015-01-03

    Categorization plays a fundamental role in organizing daily interactions with the social world. However, there is increasing recognition that social categorization is often complex, both because category membership can be ambiguous (e.g., multiracial or transgender identities) and because different categorical identities (e.g., race and gender) may interact to determine the meaning of category membership. These complex identities simultaneously impact social perceivers' impressions and social targets' own experiences of identity, thereby shaping perceptions, experiences, and interactions in fundamental ways. This review examines recent research on the perception and experience of the complex, multifaceted identities that both complicate and enrich our lives. Although research has historically tended to focus more on difficulties and challenges associated with multiple identities, increasing attention is being paid to opportunities that emerge from the possession of identities that include multiple distinct or overlapping groups. We consider how these opportunities might benefit both perceivers and targets.

    Cyberlearning tools provide cost and carbon-efficient avenues for fostering a climate literate society through online engagement with learners. With climate change education becoming a Presidential Priority in 2009, funding for grants from NSF, NASA and NOAA is leading to a new generation of cyberlearning resources that supplement existing online resources. This paper provides an overview of challenges and opportunities relating to the online delivery of high quality, often complex climate science by examining several existing and emerging efforts, including the Climate Literacy and Energy Awareness Network (CLEAN,) a National Science Digital Library Pathway, the development by CIRES Education and Outreach of the Inspiring Climate Education Excellence (ICEE) online course, TERC’s Earth Exploration Toolbook (EET,) DataTools, and EarthLab modules, the NOAA Climate Stewards Education Program (CSEP) that utilizes the NSTA E-Learning Center, online efforts by members of the Federation of Earth Science Information Partners (ESIP), UCAR’s Climate Discovery program, and the Climate Adaptation, Mitigation e-Learning (CAMeL) project. In addition, we will summarize outcomes of the Cyberlearning for Climate Literacy workshop held in Washington DC in the Fall of 2009 and examine opportunities for teachers to develop and share their own lesson plans based on climate-related web resources that currently lack built-in learning activities, assessments or teaching tips.

  4. Logistics opportunity costs: A mining case study

    Leani van Jaarsveld

    2013-11-01

    Full Text Available This study highlighted the importance of determining the impact that an ineffective mode of transport has on a firm’s transportation model and costs. The main focus of this study was to determine the logistics opportunity costs of using road transport within a mining firm. A case study approach was followed, as the investigation aimed to analyse a complex problem experienced by one company and present it in an easily understandable format. From the results of this study, it was apparent that the logistics opportunity costs associated with the mode of transport was substantial. This highlighted the need for firms to revise their choice of transport mode on a regular basis, as it has a major impact not only on their transportation costs, but also on their inventory holding and carbon emissions. The results also have implications for South Africa’s only freight railway, Transnet Freight Rail, which should not only focus on expanding its existing capacity, but also on improving its customer service delivery whilst containing tariff increases.

    Haematopoietic cell transplants are done by more than 1500 transplant centres in 75 countries, mostly for life-threatening haematological disorders. However, transplant technology and access are not uniformly-distributed worldwide. Most transplants are done in predominately Europe, North America and some Asian countries. We review transplants activity in Latin America, a geographic region with a population of more than 600 million persons living in countries with diverse economic and social development levels. The data indicate a 20-40-fold lower frequency of transplants in Latin America compared with Europe and North America. We show that although economics, infrastructure and expertise are important limitations, other variables also operate. Changes in several of these variables may substantially increase transplant activity in Latin America. PMID:26999468

    Reliable prediction of precipitation remains one of the most pivotal and complex challenges in seasonal forecasting. Previous studies show that various large-scale climate modes, such as ENSO, PNA and NAO play significant role in winter precipitation variability over the Northern America. The influences are most pronounced in years of strong indices of such climate modes. This study evaluates model bias, predictability and forecast skills of monthly winter precipitation in GEOS5-S2S 2.0 retrospective forecast from 1981 to 2016, with emphasis on the forecast skill of precipitation over North America during the extreme events of ENSO, PNA and NAO by applying EOF and composite analysis.

    The 1980s are viewed as a 'lost decade' for Latin America by many economists and politicians. Industrialists, too, bemoan the underachievement of many goals that deprived them of financial opportunities. Some of the countries' most critical observers cite the waste of petrodollars and short-sighted management as having deprived populations of longer term benefits from their oil industries. Recent trends of political-economic restructuring, however, point to a brighter future. This issue reviews the above and details some changes in the petroleum industries of a few selected countries. This issue also presents the following: (1) the ED Refining Netback Data Series for the US Gulf and West Coasts, Rotterdam, and Singapore as of August 7, 1992; and (2) the ED Fuel Price/Tax Series for countries of the Western Hemisphere, August 1992 Edition

    The near miss approach in obstetrics represents an opportunity to understand the role that structural, psychosocial and cultural determinants play in the critical obstetric experiences of women who, at the risk of death, saved their lives. This article shows the results of a narrative and critical review of the studies that have been developed from this approach in Latin America in the last 6 years. Seven international databases and 19 different journals were reviewed, originating in 7 countries. It was found that there is little production around the subject and predominated the clinical approximations referring to the diagnostic and therapeutic procedures used with this population. The predominant paradigm is positivist and most are descriptive, retrospective and cross-sectional, ranging from secondary sources of information (archives, records). It is urgent to carry out research from this approach with women, recovering the experiences they have experienced in the critical episode.

    2015-04-27

    This review introduces the America Invents Act (AIA), a comprehensive reform of U.S. law on patentability and patent enforceability that Congress enacted in 2011. The AIA's most publicized change transforms the United States from a "first-to-invent" system to a "first-inventor-to-file" regime, bringing U.S. patent law more in line with the patent systems of nearly every other industrialized country in the world. This new system requires small companies and independent inventors to toe the line against larger competitors in what many have called a "race to the patent office." But a closer look at the AIA reveals several opportunities for smaller entities that may even the playing field, particularly for innovators in the biotech sector. This article addresses changes that the AIA brings to U.S. patent law, keeping an eye toward issues relevant to biotech companies.

    The intrinsic limits of conventional cancer therapies prompted the development and application of various nanotechnologies for more effective and safer cancer treatment, herein referred to as cancer nanomedicine. Considerable technological success has been achieved in this field, but the main obstacles to nanomedicine becoming a new paradigm in cancer therapy stem from the complexities and heterogeneity of tumour biology, an incomplete understanding of nano-bio interactions and the challenges regarding chemistry, manufacturing and controls required for clinical translation and commercialization. This Review highlights the progress, challenges and opportunities in cancer nanomedicine and discusses novel engineering approaches that capitalize on our growing understanding of tumour biology and nano-bio interactions to develop more effective nanotherapeutics for cancer patients.

    2014-12-01

    Full Text Available Chikungunya virus (CHIKV and Mayaro virus (MAYV are emergent arthropod-borne viruses that produce outbreaks of acute febrile illness with arthropathy. Despite their different continental origins, CHIKV and MAYV are closely related and are components of the Semliki Forest Complex of the Alphavirus (Togaviridae. MAYV and, more recently, CHIKV, which are both transmitted by Aedes mosquitoes, have resulted in severe public health problems in the Americas, including Brazil. In this review, we present aspects of the pathogenesis, clinical presentation and treatment of febrile illnesses produced by CHIKV and MAYV. We also discuss the epidemiological aspects and effects related to the prophylaxis of infections by both viruses.

    Full Text Available This article discusses some of the changes in the connections of the European-Latin American migration system over the past decades. First, we analyse the changing trends and re-routing of the flows between the two ends of the system. Then, we address the complex rearrangements of immigration policies, which in both spaces are again beginning to turn inwards. Lastly, we briefly review the partnerships that are being established between Europe and Latin America via Spain. Within this framework, we wonder whether we are entering a new phase of the globalisation of migration, the dynamic of which is a pendulum with global and regional effects.

    2017-11-01

    Full Text Available Intraseasonal (IS variability in South America is efficiently described through the first empirical orthogonal function of filtered precipitation or outgoing longwave radiation (OLR anomalies. In the 30–90-day band, the leading OLR pattern between October and April is a dipole with centers of action in the South Atlantic Convergence Zone (SACZ and southeastern South America (SESA. The Madden Julian Oscillation (MJO was shown to have an impact on the rainfall in South America, with greater influence during the austral warm season. The aim of this study is therefore to assess the modulation of the MJO in the activity of the leading pattern of variability in South America, named the 3090-Seasonal-Intraseasonal (SIS pattern. It was found that the most intense periods of activity of the SIS pattern appear to be related to intense MJO events with coherent eastward propagation. Furthermore, positive 3090-SIS phases, associated with enhanced (inhibited convection over the SESA (SACZ region generally occur during MJO progression from the eastern Indian Ocean to the Western Pacific (i.e., Maritime Continent sector. On the contrary, negative 3090-SIS phases, associated with enhanced (inhibited convection over SACZ (SESA are observed when the MJO active phase locates between the Western Pacific and the western Indian Ocean (African sector. The 3090-SIS pattern modulation by the MJO opens the opportunity to develop skillful subseasonal prediction tools in South America.

    2017-01-01

    Full Text Available This article sought to investigate Hillary Rodham Clinton's 2016 campaign rhetoric for the U.S. President as found in her South Carolina Primary Victory Speech and Super Tuesday Victory Speech. Qualitative content analysis was used through Leanne's analytical tool of rhetorical strategies to deconstruct the texts. It gave way to new analytical narratives to decipher the core meaning as expressed in the central ideas and the main ideas of the two speeches. By so doing, access was easily made for studying the four components of Clinton's campaign rhetoric. The article showed that both speeches shared similar themes in the four components of the campaign rhetoric, illuminating consistently Clinton's lines of thought and political goals. She succinctly spelled out her agenda to make America whole again; thus, providing opportunity, dignity, and justice for every American. She framed her political stand to continue the preceding Democratic President's success to improve the American economy. She presented herself as a strong leader capable of advancing the American economy that worked for every American, breaking all barriers and restoring their common faith for a better America. She evoked hopes on the part of her prospective voters for their common better future and urged them to desire love and kindness in their lives, and use the emotion of anger against the barriers that divided them.

  18. Technical assistance in Latin America

    Oteiza-Quirno, A.

    1976-01-01

    As in the other regions, nuclear technology development in Latin America reflects mainly the degree of technological development already existing in each country. It is quite significant that in nearly all countries in Latin America the medical profession has been the first to show interest in using nuclear techniques. As a result, a country such as Uruguay has become a source of recruitment for technical assistance experts in nuclear medicine to other developing countries, while at the same time it continues to receive assistance for new sophisticated techniques from the IAEA. Part of this assistance, in turn, comes from the neighbouring countries, Argentina and Brazil. For example, an expert from Uruguay is currently assigned under an Agency programme to Costa Rica, El Salvador and Guatemala, and experts from Argentina and Brazil have been sent to Uruguay. This is an example of 'horizontal' development, meaning mutual assistance between developing countries under programmes supported by the United Nations Agencies, which is now being emphasized by the United Nations Development Programme (UNDP). Still in the field of nuclear medicine, another significant model is provided by Bolivia. With assistance from the IAEA, and thanks to the availability of a good professional infrastructure in that country, a net of nuclear medicine services has been started, consisting of a well-developed nuclear medicine centre in La Paz and regional centres in Cochabamba, Sucre and Santa Cruz. Because of its great variations in altitude, Bolivia is in the position of being able to conduct research on the adaptation of man to diverse environmental conditions. The Agency has contributed, and continues to do so, to these programmes by sending experts, providing for training abroad of Bolivian doctors under its fellowship programmes, and providing basic equipment for all four centres. Independently of the cases described above, the IAEA has implemented or is implementing a considerable

    Brazil is one of the world's largest economies and the country also has significant heavy oil reserves. This report from the National Petroleum Agency of Brazil aims at presenting the situation of the oil and gas sector in Brazil in terms of resources, production, regulatory framework and opportunities for the future. Brazil has numerous sedimentary basins at its disposal, most of them being prospected by both national and foreign companies from all over the world. Brazil has over 14 billion barrels of proven reserves, its production is 2,1 MMBbl/d and heavy oil represents almost 40% of that production. The National Petroleum Agency of Brazil is responsible for the implementation of oil sector policy with the aims of maintaining self-sufficiency, implementing good practices in terms of health and safety, and increasing local content. This paper pointed out that Brazil has an important opportunity to enhance its energy sector through the development of heavy oil.

    [figure removed for brevity, see original site] Click on the image for Opportunity Captures 'Lion King' Panorama (QTVR) This approximate true-color panorama, dubbed 'Lion King,' shows 'Eagle Crater' and the surrounding plains of Meridiani Planum. It was obtained by the Mars Exploration Rover Opportunity's panoramic camera on sols 58 and 60 using infrared (750-nanometer), green (530-nanometer) and blue (430-nanometer) filters. This is the largest panorama obtained yet by either rover. It was taken in eight segments using six filters per segment, for a total of 558 images and more than 75 megabytes of data. Additional lower elevation tiers were added to ensure that the entire crater was covered in the mosaic. This panorama depicts a story of exploration including the rover's lander, a thorough examination of the outcrop, a study of the soils at the near-side of the lander, a successful exit from Eagle Crater and finally the rover's next desination, the large crater dubbed 'Endurance'.

    NASA's Mars Exploration Rover Opportunity used its navigation camera to take the images combined into this 180-degree view of the rover's surroundings during the 1,798th Martian day, or sol, of Opportunity's surface mission (Feb. 13, 2009). North is on top. The rover had driven 111 meters (364 feet) southward on the preceding sol. Tracks from that drive recede northward in this view. For scale, the distance between the parallel wheel tracks is about 1 meter (about 40 inches). The terrain in this portion of Mars' Meridiani Planum region includes dark-toned sand ripples and lighter-toned bedrock. This view is presented as a cylindrical projection with geometric seam correction.

  2. Missed Opportunities for HIV Diagnosis.

    Science.gov (United States)

    Downing, Asia; Garcia-Diaz, Julia B

    It has been previously shown that patients may present for multiple health issues in the years preceding their initial HIV diagnosis. This retrospective cohort study analyzed the data of patients with a new HIV diagnosis, at Ochsner Health System between January 1, 2011, and December 31, 2012. The primary end point was missed opportunities, the number of healthcare visits these patients made in the 2 years prior to being diagnosed with HIV. The 125 patients in the study cohort had 649 healthcare visits during which an HIV test was not performed. These missed opportunities are the key to capturing the undiagnosed and unaware HIV-positive individual. Primary care is an ideal setting to conduct HIV testing for those who have access to regular health care. However, nontraditional providers should also be encouraged to conduct HIV testing regardless of their ability to provide treatment because evidence shows that knowledge of the diagnosis may change behavior.

    The advent of x-ray Free Electron Lasers will present a number of unique new scientific opportunities. These arise from their special characteristics which include intensely brilliant pulses of x-rays delivered in very short times, complete transverse coherence, and high photon quantum degeneracy, amongst other things. While clearly much thought needs to be given to a detailed quantitative assessment of the feasibility of various experiments using such sources, including methods of dealing with heat loads on beamline optics and radiation damage to samples, there are a number of areas in which one can see new opportunities, and other exciting possibilities about which one might speculate. In this talk the author briefly reviews some of these areas, such as x-ray holography, pump-probe type experiments, correlation spectroscopy and quantum optics experiments with x-rays

    Nuclear power plant ownership in the United States has continued its steady trend toward ownership consolidation and removal of assets from rate regulated environments that began in 1998. This is paralleled by changes in companies providing nuclear services and growing talk of building new units. World wide, new nuclear plant construction and related supplier investment is proceeding around the world. The nuclear fuel supply part of the business is seeing interest and excitement that would have been almost inconceivable a decade ago. Nuclear is now increasingly being recognized for its energy, economic and environmental benefits. For investors, this is a time of opportunity. And the opportunity is strongly supported by excellent performance trends and fundamental change sin the US electricity business. But in order to benefit from these changes, investors must remain cautious and be committed to comprehensively and thoroughly understanding the individual and interrelated technical, regulatory and political issues that surround this useful and powerful technology.

    The NASA Glenn Office of Equal Opportunity Programs works to provide quality service for all programs and/or to assist the Center in becoming a model workplace. During the summer of 2004, I worked with Deborah Cotleur along with other staff members to create and modify customer satisfaction surveys. This office aims to assist in developing a model workplace by providing functions as a change agent to the center by serving as an advisor to management to ensure equity throughout the Center. In addition, the office serves as a mediator for the Center in addressing issues and concerns. Lastly, the office provides assistance to employees to enable attainment of personal and organizational goals. The Office of Equal Opportunities is a staff office which reports and provides advice to the Center Director and Executive Leadership, implements laws, regulations, and presidential executive orders, and provides center wide leadership and assistance to NASA GRC employees. Some of the major responsibilities of the office include working with the discrimination complaints program, special emphasis programs (advisory groups), management support, monitoring and evaluation, contract compliance, and community outreach. During my internship in this office, my main objective was to create four customer satisfaction surveys based on EO retreats, EO observances, EO advisory boards, and EO mediation/counseling. I created these surveys after conducting research on past events and surveys as well as similar survey research created and conducted by other NASA centers, program for EO Advisory group members, leadership training sessions for supervisors, preventing sexual harassment training sessions, and observance events. I also conducted research on the style and format from feedback surveys from the Marshall Equal Opportunity website, the Goddard website, and the main NASA website.

    Full Text Available Objective: The main objective of this study is to define and operationalize the concept of immigrant capital, a key factor that differentiates immigrant from host country entrepreneurs in how they recognize and start new ventures. Research Design & Methods: A detailed analysis of contemporary immigrant entrepreneurship and opportunity recognition literature was carried out. Using grounded theory, we synthesized the outcomes from the analysis of eight Canadian and U.S. case studies of successful immigrant entrepreneurs with the key findings from the literature to define and develop a model of immigrant capital. Findings: Based on our grounded theory development process we show that the concept of immigrant capital as a distillate of human, cultural, economic and social capital that goes beyond expected opportunity recognition (OR drivers like prior knowledge and prior experience to differentiate and enhance the immigrant entrepreneur’s ability to recognize business opportunities compared to host country entrepreneurs. We found immigrant capital to be a consequence of being boundary spanners in host and home country networks. Implications & Recommendations: Understanding a unique resource like immigrant capital, will help immigrant as well as host country entrepreneurs further develop their opportunity recognition ability by bridging gaps and fulfilling the needs for both, immigrant and host country consumers. Contribution & Value Added: The main contribution is the theoretical development, identification and definition of the immigrant capital model and propositions that will articulate the factors that lead to the conceptualization and operationalization of immigrant capital. Furthermore, the immigrant capital model can serve host country entrepreneurs to develop cross-cultural networks and jump-start entrepreneurial activities in their home countries as well as learn how to expand their operations into global markets.

    President George Bush's 1989 challenge to America to support the Space Exploration Initiative (SEI) of ''Back to the Moon and Human Mission to Mars'' gives the space industry an opportunity to develop effective and efficient space transportation systems. This paper presents stage performance and requirements for a nuclear thermal rocket (NTR) Mars transportation system to support the human Mars mission of the SEI. Two classes of Mars mission profiles are considered in developing the NTR propulsion vehicle performance and requirements. The two Mars mission classes include the opposition class and conjunction class. The opposition class mission is associated with relatively short Mars stay times ranging from 30 to 90 days and total mission duration of 350 to 600 days. The conjunction class mission is associated with much longer Mars stay times ranging from 500 to 600 days and total mission durations of 875 to 1,000 days. Vehicle mass scaling equations are used to determine the NTR stage mass, size, and performance range required for different Mars mission opportunities and for different Mars mission durations. Mission opportunities considered include launch years 2010 to 2018. The 2010 opportunity is the most demanding launch opportunity and the 2018 opportunity is the least demanding opportunity. NTR vehicle mass and size sensitivity to NTR engine thrust level, engine specific impulse, NTR engine thrust-to-weight ratio, and Mars surface payload are presented. NTR propulsion parameter ranges include those associated with NERVA, particle bed reactor (PBR), low-pressure, and ceramic-metal-type engine design

Only a continuing program of radiometric dating and careful stratigraphic correlations can address the lingering ambiguity about the emergence and spread of Clovis culture.

    The underlying rationale to support interdisciplinary collaboration in geriatrics and gerontology is based on the complexity of elderly care. The most important characteristic about interdisciplinary health care teams for older people in Latin America is their subjective-basis framework. In other regions, teams are organized according to a…

  17. Reproductive governance in Latin America.

    Science.gov (United States)

    Morgan, Lynn M; Roberts, Elizabeth F S

    2012-01-01

    This paper develops the concept of reproductive governance as an analytic tool for tracing the shifting political rationalities of population and reproduction. As advanced here, the concept of reproductive governance refers to the mechanisms through which different historical configurations of actors - such as state, religious, and international financial institutions, NGOs, and social movements - use legislative controls, economic inducements, moral injunctions, direct coercion, and ethical incitements to produce, monitor, and control reproductive behaviours and population practices. Examples are drawn from Latin America, where reproductive governance is undergoing a dramatic transformation as public policy conversations are coalescing around new moral regimes and rights-based actors through debates about abortion, emergency contraception, sterilisation, migration, and assisted reproductive technologies. Reproductive discourses are increasingly framed through morality and contestations over 'rights', where rights-bearing citizens are pitted against each other in claiming reproductive, sexual, indigenous, and natural rights, as well as the 'right to life' of the unborn. The concept of reproductive governance can be applied to other settings in order to understand shifting political rationalities within the domain of reproduction.

  18. The Norse discovery of America.

    2005-12-01

    In the late 8th century, the stage for Viking expansion was set by commercial expansion in northwest Europe, the pressure of an increasing population in limited territorial reserves, and the development of the Viking ships. The Norsemen traveled extensively over the oceans, south to the Holy Land, and north to the White Sea and settled over a wide area from Sicily to Greenland. Historical sources, including the reports by Adam of Bremen and the Icelandic Sagas, describe several expeditions from Greenland to Vinland (somewhere along the east coast of North America) in approximately AD 1000 and later. Historians have arrived at highly different conclusions with respect to the location of Vinland (from Labrador to Georgia), but, in 1960, the Norwegian explorer Helge Ingstad localized ancient house sites on L'Ans aux Meadows, a small fishing village on the Northern beaches of Newfoundland. From 1961 to 1969, Ingstad and his wife, Anne Stine (an archaeologist), led several archaeological expeditions that revealed Viking turf houses with room for approximately 100 people. They also excavated a smithy, outdoor cooking pits, boathouses, a bathhouse, and enclosures for cattle, in addition to several Viking artifacts. The finds were C dated to AD 990 +/- 30. The present report reviews historical and archaeological evidence indicating the sites to which the Vikings traveled and attempted to settle in the new world.

    Full Text Available In addition to increasing our knowledge and understanding of the naturalists who explored America at various times, particularly in the 18th and 19th centuries, we seek to discuss the personal, intimate, private, and sentimental nature of individuals who are usually described as well-bred, parsimonious, unfeeling, objective, rigorous, and methodical. For the same reason, perhaps, they are assumed to have stayed aloof from any form of sentimental or passionate relationships in the course of their excursions, despite the fact that the latter often lasted not for months but for years, and that in some instances were not conducted overland but involved prolonged voyages on the high seas.

    Además de avanzar en el conocimiento y comprensión de los naturalistas que exploraron América en algún momento, particularmente en los siglos XVIII y XIX, nos interesa relevar la dimensión personal, íntima, privada, sentimental, de sujetos que corrientemente son presentados como hombres comedidos, parcos, fríos, objetivos, rigurosos y metódicos y, tal vez por eso, se supone, ajenos a cualquier tipo de relación sentimental o pasional durante sus excursiones. Esto, a pesar de que muchas de ellas se prolongaron no ya por meses, sino que por años y que algunas de ellas no fueron itinerarios terrestres, sino que esencialmente marítimos, con largas temporadas en alta mar.

  20. Ending child homelessness in America.

    2010-10-01

    Approximately 1.5 million children experience homelessness in America each year. The current economic recession and staggering numbers of housing foreclosures have caused the numbers of homeless families to increase dramatically. The impact of homelessness on families and children is devastating. Without a place to call home, children are severely challenged by unpredictability, dislocation, and chaos. Homelessness and exposure to traumatic stresses place them at high risk for poor mental health outcomes. Despite the pressing needs of these children, federal policy during the last decade has focused primarily on chronically homeless adult individuals-to the exclusion of the families. In 2010, however, the U.S. Interagency Council on Homelessness issued a comprehensive plan to eradicate homelessness for all people through interagency collaboration and aligning mainstream services. A key goal is to prevent and end homelessness for families, youth, and children within 10 years. This policy-focused article describes several tools that can be used to help achieve this goal, including: general principles of care for serving homeless families and children; BSAFE-a promising practice that helps families access community-based services and supports; and the Campaign to End Child Homelessness aimed at action on behalf of homeless families and children at the national, state, and local levels. © 2010 American Orthopsychiatric Association.

    2015-11-01

    In the present day, Latin America is the most urbanised region - and also the most inequitable - on the planet, which means that its urban areas amass both huge wealth and huge poverty. Within this context, dealing with climate change is also a chance to increase citizens' well-being. Better public transport and more efficient energy and waste management are, besides being effective measures to reduce emissions, ultimately actions with a strong social component and work towards improving transportation and public health care and generate savings for citizens. Equally, actions geared towards boosting urban resilience represent measures that go beyond adaptation responses to climate change and primarily benefit those that are most vulnerable in the population. In the context of the future new global climate agreement, cities are taking a more prominent role in this new urban era, and gained in importance in the Sustainable Development Goals, LAC has a lot to give in the lessons learned from urbanisation. Rapidly urbanising regions like Asia and Africa, where population growth will be concentrated in cities in the present and near future, could learn a lot from the urbanisation process that has occurred, and continues to occur, in LAC. From the transport industry to energy and water, successful cases are numerous and varied, as are the setbacks, from which valuable lessons can be drawn for the purposes of more effectively facing up to this new global urban reality

    The America Saves! Energizing Main Street Small Businesses project engaged the 1,200-member National Main Street Center (NMSC) network of downtown organizations and other local, regional, and national partners to test a methodology for sharing customized energy efficiency information with owners of commercial buildings smaller than 50,000 square feet. Led by the National Trust for Historic Preservation’s Preservation Green Lab, the project marshalled local staff and volunteers to gather voluntarily-disclosed energy use information from participating businesses. This information was analyzed using a remote auditing tool (validated by the National Renewable Energy Lab) to assess energy savings opportunities and design retrofit strategies targeting seven building types (food service and sales, attached mixed-use, strip mall, retail, office, lodging, and schools). The original project design contemplated extensive leveraging of the Green Button protocol for sharing annualized utility data at a district scale. Due the lack of adoption of Green Button, the project partners developed customized approaches to data collection in each of twelve pilot communities. The project team encountered considerable challenges in gathering standardized annual utility data from local partners. After overcoming these issues, the data was uploaded to a data storehouse. Over 450 properties were benchmarked and the remote auditing tool was tested using full building profiles and utility records for more than 100 commercial properties in three of the pilot communities. The audit tool demonstrated potential for quickly capturing, analyzing, and communicating energy efficiency opportunities in small commercial buildings. However, the project team found that the unique physical characteristics and use patterns (partial vacancy, periodic intensive uses) of small commercial buildings required more trouble-shooting and data correction than was anticipated. In addition, the project revealed that

    Full Text Available A scientific approach to management was initiated for the first time in America in the late 19th century. Scientific management arose mainly from the need to increase efficiency in America, but other key factors were the spread of big businesses and the expanding application of science in industry. The aims of our paper are to present the emergence of scientific management in America and to emphasize the contribution of some of the most representatives American authors to its development. The methodological approach is literature review. Our paper shows that scientific management was essentially an American achievement that provided useful lessons for the whole human society.

    Mathieu JP Poirier

    2012-01-01

    Full Text Available Background: The re-emergence of cholera in Haiti has established a new reservoir for the seventh cholera pandemic which threatens to spread to other countries in the Americas. Materials and Methods: Statistics from this new epidemic are compared to the 1991 Peru epidemic, which demonstrated the speed and complexity with which this disease can spread from country to country. Environmental factors implicated in the spread of Vibrio cholerae such as ocean currents and temperatures, as well as biotic factors from zooplankton to waterfowl pose a risk for many countries in the Americas. Results: The movement of people and goods from Hispaniola are mostly destined for North America, but occur to some degree throughout the Americas. These modes of transmission, and the probability of uncontrolled community spread beyond Hispaniola, however, are completely dependent upon risk factors within these countries such as water quality and availability of sanitation. Although North America has excellent coverage of these deterrents to the spread of infectious gastrointestinal diseases, many countries throughout Latin America and the Caribbean lack these basic services and infrastructures. Conclusions : In order to curb the immediate spread of cholera in Hispaniola, treatment availability should be expanded to all parts of the island and phase II epidemic management initiatives must be developed.

    Migration patterns in Latin America have changed significantly in recent decades, particularly since the onset of global recession in 2007. These recent economic changes have highlighted and exacerbated the weakness of evidence from Latin America regarding migration-a crucial determinant of health. Migration patterns are constantly evolving in Latin America, but research on migration has not developed at the same speed. This article focuses on the need for better understanding of the living conditions and health of migrant populations in Latin America within the context of the recent global recession. The authors explain how new data on migrant well-being could be obtained through improved evidence from censuses and ongoing research surveys to 1) better inform policy-makers about the needs of migrant populations in Latin America and 2) help determine better ways of reaching undocumented immigrants. Longitudinal studies on immigrants in Latin America are essential for generating a better representation of migrant living conditions and health needs during the initial stages of immigration and over time. To help meet this need, the authors support the promotion of sustainable sources of data and evidence on the complex relationship between migration and health.

    [figure removed for brevity, see original site] Click on the image for Opportunity's 'Rub al Khali' Panorama (QTVR) This panoramic image, dubbed 'Rub al Khali,' was acquired by NASA's Mars Exploration Rover Opportunity on the plains of Meridiani during the period from the rover's 456th to 464th sols on Mars (May 6 to May 14, 2005). Opportunity was about 2 kilometers (1.2 miles) south of 'Endurance Crater' at a place known informally as 'Purgatory Dune.' The rover was stuck in the dune's deep fine sand for more than a month. 'Rub al Khali' (Arabic translation: 'the empty quarter') was chosen as the name for this panorama because it is the name of a similarly barren, desolate part of the Saudi Arabian desert on Earth. The view spans 360 degrees. It consists of images obtained in 97 individual pointings of the panoramic camera. The camera took images with five camera filters at each pointing. This 22,780-by-6,000-pixel mosaic is an approximately true-color rendering generated using the images acquired through filters admitting light wavelengths of 750, 530, and 480 nanometers. Lighting varied during the nine sols it took to acquire this panorama, resulting in some small image seams within the mosaic. These seams have been smoothed in sky parts of the mosaic to better simulate the vista that a person would see if able to view it all at the same time on Mars. Opportunity's tracks leading back to the north (center of the panorama) are a reminder of the rover's long trek from Endurance Crater. The deep ruts dug by Opportunity's wheels as it became stuck in the sand appear in the foreground. The crest and trough of the last ripple the rover crossed before getting stuck is visible in the center. These wind-formed sand features are only about 10 to 15 centimeters (4 to 6 inches) tall. The crest of the actual ripple where the rover got stuck can be seen just to the right of center. The tracks and a few other places on and near ripple crests can be seen in this color image to

  9. Compelling Research Opportunities using Isotopes

    Isotopes are vital to the science and technology base of the US economy. Isotopes, both stable and radioactive, are essential tools in the growing science, technology, engineering, and health enterprises of the 21st century. The scientific discoveries and associated advances made as a result of the availability of isotopes today span widely from medicine to biology, physics, chemistry, and a broad range of applications in environmental and material sciences. Isotope issues have become crucial aspects of homeland security. Isotopes are utilized in new resource development, in energy from bio-fuels, petrochemical and nuclear fuels, in drug discovery, health care therapies and diagnostics, in nutrition, in agriculture, and in many other areas. The development and production of isotope products unavailable or difficult to get commercially have been most recently the responsibility of the Department of Energy's Nuclear Energy program. The President's FY09 Budget request proposed the transfer of the Isotope Production program to the Department of Energy's Office of Science in Nuclear Physics and to rename it the National Isotope Production and Application program (NIPA). The transfer has now taken place with the signing of the 2009 appropriations bill. In preparation for this, the Nuclear Science Advisory Committee (NSAC) was requested to establish a standing subcommittee, the NSAC Isotope Subcommittee (NSACI), to advise the DOE Office of Nuclear Physics. The request came in the form of two charges: one, on setting research priorities in the short term for the most compelling opportunities from the vast array of disciplines that develop and use isotopes and two, on making a long term strategic plan for the NIPA program. This is the final report to address charge 1. NSACI membership is comprised of experts from the diverse research communities, industry, production, and homeland security. NSACI discussed research opportunities divided into three areas: (1

    Ranked among the 50 largest food service corporations in America, the Randolph-Sheppard Business Enterprise Program (BEP) represents a challenging and rewarding career opportunity for Americans who are legally blind. In recent years, however, the number of facilities and facility managers has declined. Multicultural consumers represent a major emerging growth market. The multicultural market is one of the most overlooked retail markets in the United States--and the one with the most buying power and growth potential. Multicultural marketing is among the least understood strategies available to facility managers, vocational rehabilitation counselors and BEP directors. Four major minority markets are discussed and marketing strategies are offered to help BEPs target and serve these unique consumers.

    Plasmodium vivax is the most prevalent human malaria parasite in the Americas. Previous studies have contrasted the genetic diversity of parasite populations in the Americas with those in Asia and Oceania, concluding that New World populations exhibit low genetic diversity consistent with a recent introduction. Here we used an expanded sample of complete mitochondrial genome sequences to investigate the diversity of P. vivax in the Americas as well as in other continental populations. We show that the diversity of P. vivax in the Americas is comparable to that in Asia and Oceania, and we identify several divergent clades circulating in South America that may have resulted from independent introductions. In particular, we show that several haplotypes sampled in Venezuela and northeastern Brazil belong to a clade that diverged from the other P. vivax lineages at least 30,000 years ago, albeit not necessarily in the Americas. We propose that, unlike in Asia where human migration increases local genetic diversity, the combined effects of the geographical structure and the low incidence of vivax malaria in the Americas has resulted in patterns of low local but high regional genetic diversity. This could explain previous views that P. vivax in the Americas has low genetic diversity because these were based on studies carried out in limited areas. Further elucidation of the complex geographical pattern of P. vivax variation will be important both for diversity assessments of genes encoding candidate vaccine antigens and in the formulation of control and surveillance measures aimed at malaria elimination.

  14. Globalization and Land-Use Transitions in Latin America

    Directory of Open Access Journals (Sweden)

    H. Ricardo. Grau

    2008-12-01

    Full Text Available Current socioeconomic drivers of land-use change associated with globalization are producing two contrasting land-use trends in Latin America. Increasing global food demand (particularly in Southeast Asia accelerates deforestation in areas suitable for modern agriculture (e.g., soybean, severely threatening ecosystems, such as Amazonian rain forests, dry forests, and subtropical grasslands. Additionally, in the coming decades, demand for biofuels may become an emerging threat. In contrast, high yields in modern agricultural systems and rural-urban migration coupled with remittances promote the abandonment of marginal agricultural lands, thus favoring ecosystem recovery on mountains, deserts, and areas of poor soils, while improving human well-being. The potential switch from production in traditional extensive grazing areas to intensive modern agriculture provides opportunities to significantly increase food production while sparing land for nature conservation. This combination of emerging threats and opportunities requires changes in the way the conservation of Latin American ecosystems is approached. Land-use efficiency should be analyzed beyond the local-based paradigm that drives most conservation programs, and focus on large geographic scales involving long-distance fluxes of products, information, and people in order to maximize both agricultural production and the conservation of environmental services.

    This presentation analyzed the current global wood pellet market and evaluated some of the forces currently driving market expansion. Global wood pellet production statistics were also presented. Large forest companies are now expanding into the energy sector and seeking to produce processing heat from biomass in addition to creating value-added products such as wood pellets, ethanol and electricity. The European biomass action plan has promised to increase production of energy from biomass from 4 per cent to 8 per cent by 2010. Various biomass boiler eco-directives have been established internationally, and some countries in Europe are now aggressively promoting the use of combined heat and power (CHP) systems. Biofuels mixing quotas have been established in various countries as well as tax relief plans for users of bio-fuels. As a result of these developments, along with various new directives, wood pellet consumption in Europe has increased from approximately 1 million tonnes in 2000 to 5 million tonnes in 2005. Consumption of wood pellets in Canada has increased only marginally in the same time period. While Canada currently exported 330,000 tonnes of wood pellets to Europe in 2006, it is expected that exports will increase to 800,000 tonnes by 2010. Other potential markets for Canadian wood pellets include South America, South Africa, Japan, and China. Production of wood pellets in China is expected to increase from current negligible production figures to approximately 50 million tonnes by 2020. Biomass research and development activities in Europe and North America are continuing to improve the calorific value of wood pellets and improve their mechanical strength. Researchers are also investigating methods of lowering wood pellet production costs. refs., tabs., figs

  19. Parasites of freshwater fishes in North America: why so neglected?

    Science.gov (United States)

    Scholz, Tomáš; Choudhury, Anindo

    2014-02-01

    Fish parasitology has a long tradition in North America and numerous parasitologists have contributed considerably to the current knowledge of the diversity and biology of protistan and metazoan parasites of freshwater fishes. The Journal of Parasitology has been essential in disseminating this knowledge and remains a significant contributor to our understanding of fish parasites in North America as well as more broadly at the international level. However, with a few exceptions, the importance of fish parasites has decreased during the last decades, which is reflected in the considerable decline of funding and corresponding decrease of attention paid to these parasites in Canada and the United States of America. After the 'golden age' in the second half of the 20th Century, fish parasitology in Canada and the United States went in a new direction, driven by technology and a shift in priorities. In contrast, fish parasitology in Mexico has undergone rapid development since the early 1990s, partly due to extensive international collaboration and governmental funding. A critical review of the current data on the parasites of freshwater fishes in North America has revealed considerable gaps in the knowledge of their species composition, host specificity, life cycles, evolution, phylogeography, and relationships with their fish hosts. As to the key question, "Why so neglected?" this is probably because: (1) fish parasites are not in the forefront due to their lesser economic importance; (2) there is little funding for this kind of research, especially if a practical application is not immediately apparent; and (3) of shifting interests and a shortage of key personalities to train a new generation (they switched to marine habitats or other fields). Some of the opportunities for future research are outlined, such as climate change and cryptic species diversity. A significant problem challenging future research seems to be the loss of trained and experienced fish

  20. Cultural learning and the Clovis colonization of North America.

    Science.gov (United States)

    O'Brien, Michael J; Buchanan, Briggs

    2017-11-01

    The timing of the earliest colonization of North America is debatable, but what is not at issue is the point of origin of the early colonists: Humans entered the continent from Beringia and then made their way south along or near the Pacific Coast and/or through a corridor that ran between the Cordilleran and Laurentide ice sheets in western North America. At some point, they abandoned their Arctic-based tool complex for one more adapted to an entirely different environment. That new techno-complex is termed "Clovis"; its dispersal allows us to examine, at a fine scale, how colonization processes played out across a vast continent that at the time had, at best, a very small resident population. Clovis has figured prominently in American archeology since the first Clovis points were identified in eastern New Mexico in the 1930s. However, the successful marriage of learning models grounded in evolutionary theory and modern analytical methods that began roughly a decade ago has begun to pay significant dividends in terms of what we know about the rapid spread of human groups across the last sizable landmass to witness human occupation. © 2017 Wiley Periodicals, Inc.

    In recent years, Latin America`s hydrocarbons sector has been characterized by reorganization, revitalization, regional cooperation, environmental awakening, and steady expansion. The pattern of these changes, which appear to be the megatrends of the region`s hydrocarbons sector development, will continue during the rest of the 1990s. To further study the current situation and future prospects of Latin America`s hydrocarbons sector, we critically summarize in this short article the key issues in the region`s oil and gas development. These megatrends in Latin America`s hydrocarbons sector development will impact not only the future energy demand and supply in the region, but also global oil flows in the North American market and across the Pacific Ocean. Each country is individually discussed; pipelines to be constructed are discussed also.

    This article is a summary of presentations made during the 1997 Winter Meeting panel session on Power and Natural Gas in Latin America: Towards an Integrated Market. Reregulation and demand for energy resources to support economic growth are driving international natural gas and electricity exchange initiatives. Panelists focused on the gas and electric power industry in Latin America in terms of the: transport of gas or transmission of electricity; energy market integration in the southern cone of South America; and issues on gas use for electricity generation in South America countries. Countries such as Argentina, Bolivia, and Peru will export natural gas to Brazil, Uruguay, Paraguay and Chile, an the energy matrices of these countries will change

    Full Text Available South American countries participate on the new international stage in very diverse ways, reflecting their different political models and preferences. The big changes that have seriously affected the international system have had a profound impact on South America. The United States are no longer the dominant power in the world, nor in their old backyard, South America. Europe retains a certain role in the area, but the crisis it is undergoing is limiting its influence in the region. Relations between South American counties are increasing, but not within the framework of a single, coherent integration process. China, India, Korea, and other Asian countries are joining Japan’s traditional and always discreet presence in the area, but up to now Asia has confined itself to economic exchanges with South America. In general, South America is consolidating itself as the second-largest emerging region on the planet, after Asia, and is projecting that reality in its international relations.

  9. Latin America: population and internal unrest.

    Science.gov (United States)

    Wiarda, J H; Siqueira Wiarda, I

    1985-09-01

    This discussion of population and internal unrest in Latin America covers the following: pressures on land and agriculture; economic frustrations; the youth and radicalism; rising social tensions; and political instability. At current growth rates, Latin America's population is projected to increases between 1981 2001 by 225 million people. This staggering population growth is likely to have serious political, economic, social, strategic, and other implications. The strong opposition to family planning which came principally from nationlists, the military, and the church during the 1960s has changed to general support for voluntary family planning programs in much of Latin America. Too rapid population growth now is viewed widely as aggravating the problems of development and putting severe strains on services and facilities. The wish to limit family size is particularly strong among women. Most of Latin America's untapped land is unusable, either so steeply mountainous, densely tropical, or barren of topsoil that it cannot support life at even the most meager level of subsistence. Food production in most of Latin America has not kept pace with population growth. Since most new agricultural production is oriented toward exports rather than home consumption, conditions for most rural populations are worsening. Economic dilemmas facing Latin America include widespread poverty, the world's highest per capita debt, unemployment and underemployment that may reach between 40-50% of the workforce, negative economic growth rates over the past 5 years, immense income inequalities, declining terms of trade, extensive capital flight, little new investment or foreign assistance, increased protectionism on the part of those countriews with whom Latin America must trade, rising prices for the goods Latin America must import, and (in some countries) devastation of the economic infrastrucutre by guerrilla forces. The unprecedent flow from the countryside has made Latin America the

  13. On the Path to SunShot. Emerging Opportunities and Challenges in U.S. Solar Manufacturing

    2016-05-01

    This report provides insights into photovoltaic (PV) and concentrating solar power (CSP) manufacturing in the context of the U.S. Department of Energy's SunShot Initiative. Although global PV price reductions and deployment have been strong recently, PV manufacturing faces challenges. Slowing rates of manufacturing cost reductions, combined with the relatively low price of incumbent electricity generating sources in most large global PV markets, may constrain profit opportunities for firms and poses a potential challenge to the sustainable operation and growth of the global PV manufacturing base. In the United States, manufacturers also face a factors-of-production cost disadvantage compared with competing nations. However, the United States is one of the world's most competitive and innovative countries as well as one of the best locations for PV manufacturing. In conjunction with strong projected PV demand in the United States and across the Americas, these advantages could increase the share of PV technologies produced by U.S. manufacturers as the importance of innovation-driven PV cost reductions increases. Compared with PV, CSP systems are much more complex and require a much larger minimum effective scale, resulting in much higher total CAPEX requirements for system construction, lengthier development cycles, and ultimately higher costs of energy produced. The global lack of consistent CSP project development creates challenges for companies that manufacture specialty CSP components, and the potential lack of a near-term U.S. market could hinder domestic CSP manufacturers. However, global and U.S. CSP deployment is expected to expand beyond 2020, and U.S. CSP manufacturers could benefit from U.S. innovation advantages similar to those associated with PV. Expansion of PV and CSP manufacturing also presents U.S. job-growth opportunities.

    Today's lending dynamics are leading many hospitals to revisit their strategies for accessing capital: Fixed-rate bonds will likely be a centerpiece of just about any organization's capital structure going forward. Joint partnerships with physicians may provide opportunity for specific service-line strength without heavy investment in facility and equipment. Many hospitals are evaluating the sale of noncore and core assets as well as the use of ground leases or arrangements that would permit them to repurchase the assets at a later time.

    The miniaturization, sophistication, proliferation, and accessibility of technologies are enabling the capture of more and previously inaccessible phenomena in Parkinson's disease (PD). However, more information has not translated into a greater understanding of disease complexity to satisfy diagnostic and therapeutic needs. Challenges include noncompatible technology platforms, the need for wide-scale and long-term deployment of sensor technology (among vulnerable elderly patients in particular), and the gap between the "big data" acquired with sensitive measurement technologies and their limited clinical application. Major opportunities could be realized if new technologies are developed as part of open-source and/or open-hardware platforms that enable multichannel data capture sensitive to the broad range of motor and nonmotor problems that characterize PD and are adaptable into self-adjusting, individualized treatment delivery systems. The International Parkinson and Movement Disorders Society Task Force on Technology is entrusted to convene engineers, clinicians, researchers, and patients to promote the development of integrated measurement and closed-loop therapeutic systems with high patient adherence that also serve to (1) encourage the adoption of clinico-pathophysiologic phenotyping and early detection of critical disease milestones, (2) enhance the tailoring of symptomatic therapy, (3) improve subgroup targeting of patients for future testing of disease-modifying treatments, and (4) identify objective biomarkers to improve the longitudinal tracking of impairments in clinical care and research.

    2012-12-01

    Meeting the increasing global demand for energy over the next several decades presents daunting challenges to engineers and scientists, including geoscientists of all disciplines. Many opportunities exist for geophysicists to find and produce oil and gas in a safe, environmentally responsible and affordable manner. Successful oil and gas exploration involves a 'Plates to Pores' approach that integrates multi-scale data from satellites, marine and land seismic and non-seismic field surveys, lab experiments, and even electron microscopy. The petroleum industry is at the forefront of using high performance computing to develop innovative methods to process and analyze large volumes of seismic data and perform realistic numerical modeling, such as finite element fluid flow and rock deformation simulations. Challenging and rewarding jobs in exploration, production and research exist for students with BS/BA, MS and PhD degrees. Geophysics students interested in careers in the petroleum industry should have a broad foundation in science, math and fundamental geosciences at the BS/BA level, as well as mastery of the scientific method, usually gained through thesis work at MS and PhD levels. Field geology or geophysics experience is also valuable. Other personal attributes typical for geoscientists to be successful in industry include a passion for solving complex geoscience problems, the flexibility to work on a variety of assignments throughout a career and skills such as teamwork, communication, integration and leadership. In this presentation we will give examples of research, exploration and production opportunities for geophysicists in petroleum companies and compare and contrast careers in academia vs. industry.

  6. Additive manufacturing in production: challenges and opportunities

    Ahuja, Bhrigu; Karg, Michael; Schmidt, Michael

    2015-03-01

    Additive manufacturing, characterized by its inherent layer by layer fabrication methodology has been coined by many as the latest revolution in the manufacturing industry. Due to its diversification of Materials, processes, system technology and applications, Additive Manufacturing has been synonymized with terminology such as Rapid prototyping, 3D printing, free-form fabrication, Additive Layer Manufacturing, etc. A huge media and public interest in the technology has led to an innovative attempt of exploring the technology for applications beyond the scope of the traditional engineering industry. Nevertheless, it is believed that a critical factor for the long-term success of Additive Manufacturing would be its ability to fulfill the requirements defined by the traditional manufacturing industry. A parallel development in market trends and product requirements has also lead to a wider scope of opportunities for Additive Manufacturing. The presented paper discusses some of the key challenges which are critical to ensure that Additive Manufacturing is truly accepted as a mainstream production technology in the industry. These challenges would highlight on various aspects of production such as product requirements, process management, data management, intellectual property, work flow management, quality assurance, resource planning, etc. In Addition, changing market trends such as product life cycle, mass customization, sustainability, environmental impact and localized production will form the foundation for the follow up discussion on the current limitations and the corresponding research opportunities. A discussion on ongoing research to address these challenges would include topics like process monitoring, design complexity, process standardization, multi-material and hybrid fabrication, new material development, etc.

  7. Characterizing commercial oil palm expansion in Latin America: land use change and trade

    Science.gov (United States)

    Furumo, Paul Richard; Aide, T. Mitchell

    2017-02-01

    Commodity crop expansion has increased with the globalization of production systems and consumer demand, linking distant socio-ecological systems. Oil palm plantations are expanding in the tropics to satisfy growing oilseed and biofuel markets, and much of this expansion has caused extensive deforestation, especially in Asia. In Latin America, palm oil output has doubled since 2001, and the majority of expansion seems to be occurring on non-forested lands. We used MODIS satellite imagery (250 m resolution) to map current oil palm plantations in Latin America and determined prior land use and land cover (LULC) using high-resolution images in Google Earth. In addition, we compiled trade data to determine where Latin American palm oil flows, in order to better understand the underlying drivers of expansion in the region. Based on a sample of 342 032 ha of oil palm plantations across Latin America, we found that 79% replaced previously intervened lands (e.g. pastures, croplands, bananas), primarily cattle pastures (56%). The remaining 21% came from areas that were classified as woody vegetation (e.g. forests), most notably in the Amazon and the Petén region in northern Guatemala. Latin America is a net exporter of palm oil but the majority of palm oil exports (70%) stayed within the region, with Mexico importing about half. Growth of the oil palm sector may be driven by global factors, but environmental and economic outcomes vary between regions (i.e. Asia and Latin America), within regions (i.e. Colombia and Peru), and within single countries (i.e. Guatemala), suggesting that local conditions are influential. The present trend of oil palm expanding onto previously cleared lands, guided by roundtable certifications programs, provides an opportunity for more sustainable development of the oil palm sector in Latin America.

  8. Arctic resources : a mechatronics opportunity

    McKean, M.; Baiden, G. [Penguin Automated Systems Inc., Naughton, ON (Canada)

    2008-07-01

    This paper discussed the telerobotic mechatronics opportunities that exist to access mineral resources in the Arctic. The Mining Automation Project (MAP) determined that telerobotics could contribute to productivity gains while providing increased worker safety. The socio-economic benefits of advanced mechatronics for Arctic resource development are particularly attractive due to reduced infrastructure needs; operating costs; and environmental impacts. A preliminary analysis of mining transportation options by the authors revealed that there is a case for in-situ resource utilization (ISRU) for oil and gas processing to address resource development. The ISRU options build on concepts developed to support space exploration and were proposed to reduce or modify transportation loads to allow more sustainable and efficient Arctic resource development. Many benefits in terms of efficiency could be achieved by combining demonstrated mechatronics with ISRU because of the constrained transportation infrastructure in the Arctic. In the context of harsh environment operations, mechatronics may provide an opportunity for undersea resource facilities. 15 refs., 6 figs.

    Maritimes and Northeast Pipelines Company is constructing a 1048 km underground gas transmission pipeline that will transport Sable natural gas to markets in Nova Scotia, New Brunswick and New England. The Sable Offshore Energy Project brings opportunities for new industries to Atlantic Canada, including the potential for future Sable gas exploration, development and production which will provide thousands of jobs and benefits for local businesses during the construction phase. Maritimes and Northeast Pipelines plan to maximize local content for the construction of the 565 km Canadian portion of the pipeline. The construction phase alone should create about 1,500 jobs during peak times. Seventy per cent of the labour will be sourced locally. Clean-up, landscaping, fencing and tile repair, monitoring services and pipeline inspection are some of the other opportunities that will be contracted to local businesses. Major long-term benefits of the project are expected to be in the construction of lateral or feeder pipelines and in the construction of gas distribution utilities

    The NASA Life Sciences Research Capabilities Team (LSRCT) has been discussing deep space research needs for the last two years. NASA's programs conducting life sciences studies - the Human Research Program, Space Biology, Astrobiology, and Planetary Protection - see the Deep Space Gateway (DSG) as affording enormous opportunities to investigate biological organisms in a unique environment that cannot be replicated in Earth-based laboratories or on Low Earth Orbit science platforms. These investigations may provide in many cases the definitive answers to risks associated with exploration and living outside Earth's protective magnetic field. Unlike Low Earth Orbit or terrestrial locations, the Gateway location will be subjected to the true deep space spectrum and influence of both galactic cosmic and solar particle radiation and thus presents an opportunity to investigate their long-term exposure effects. The question of how a community of biological organisms change over time within the harsh environment of space flight outside of the magnetic field protection can be investigated. The biological response to the absence of Earth's geomagnetic field can be studied for the first time. Will organisms change in new and unique ways under these new conditions? This may be specifically true on investigations of microbial communities. The Gateway provides a platform for microbiology experiments both inside, to improve understanding of interactions between microbes and human habitats, and outside, to improve understanding of microbe-hardware interactions exposed to the space environment.

  11. Mercati, identità e diritto in America Latina - Markets, identity and law in Latin America

    Antonio Luigi Palmisano

    2014-06-01

    Full Text Available Identities, and ethnic identities in particular, are the in fieri result of complex social and cultural processes which show how much the identities of the social actors are multiple, in transition, situational and constantly negotiated. However, the structure of the dominating social and political order of the contemporary post-global era coincides with the order of the financial markets. Based upon the ethnographies of Latin America this article claims that this new order interacts antagonistically with the structures which are acknowledged, proposed or anyway regulated by both the national juridical systems (customary law, Constitution, civil and penal law and international law toward processes of fixation and reification of the identities. The social actor is thus reduced and constrained in the mono-role of consumer up to indebtedness and to his consequent epiphany as res. The way to a law without State is thus open: an icon and embodiment of elitist ideologies that are at the same time active and hidden but deeply inscribed the new order of the financial markets which convey social Darwinism and the subordination of man to financial capital.

  12. Earthquake swarms in South America

    Holtkamp, S. G.; Pritchard, M. E.; Lohman, R. B.

    2011-10-01

    We searched for earthquake swarms in South America between 1973 and 2009 using the global Preliminary Determination of Epicenters (PDE) catalogue. Seismicity rates vary greatly over the South American continent, so we employ a manual search approach that aims to be insensitive to spatial and temporal scales or to the number of earthquakes in a potential swarm. We identify 29 possible swarms involving 5-180 earthquakes each (with total swarm moment magnitudes between 4.7 and 6.9) within a range of tectonic and volcanic locations. Some of the earthquake swarms on the subduction megathrust occur as foreshocks and delineate the limits of main shock rupture propagation for large earthquakes, including the 2010 Mw 8.8 Maule, Chile and 2007 Mw 8.1 Pisco, Peru earthquakes. Also, subduction megathrust swarms commonly occur at the location of subduction of aseismic ridges, including areas of long-standing seismic gaps in Peru and Ecuador. The magnitude-frequency relationship of swarms we observe appears to agree with previously determined magnitude-frequency scaling for swarms in Japan. We examine geodetic data covering five of the swarms to search for an aseismic component. Only two of these swarms (at Copiapó, Chile, in 2006 and near Ticsani Volcano, Peru, in 2005) have suitable satellite-based Interferometric Synthetic Aperture Radar (InSAR) observations. We invert the InSAR geodetic signal and find that the ground deformation associated with these swarms does not require a significant component of aseismic fault slip or magmatic intrusion. Three swarms in the vicinity of the volcanic arc in southern Peru appear to be triggered by the Mw= 8.5 2001 Peru earthquake, but predicted static Coulomb stress changes due to the main shock were very small at the swarm locations, suggesting that dynamic triggering processes may have had a role in their occurrence. Although we identified few swarms in volcanic regions, we suggest that particularly large volcanic swarms (those that

    Throughout the 1990's to Year 2000, energy integration, and particularly natural gas integration, was seen as a major goal in the Southern Cone of South America, The regional perspective for energy was related to an even more challenging objective - Latin American economic integration, which was quickly moving forward by the constitution of MERCOSUR, the free trade zone built by Argentina, Brazil, Uruguay and Paraguay, and also having Bolivia and Chile as special partners. MERCOSUR was getting stronger and becoming a successful political project. Trade conflicts existed, but they were considered normal and nobody would disagree about the viability of MERCOSUR. By the beginning of the 21. Century, the economic integration process in South America was already advancing timidly as compared to the impetus from the beginning of 1990's. MERCOSUR started facing complex and almost insurmountable challenges after the numerous global financial crises (from 1998 to 2003) which had affected the economic balances in the region. Energy and gas integration in South America has equally lost perspective as fast as the importance of economic integration has declined. The economic crises in the region and poor energy policies have discouraged energy companies to invest. The paper presents this recent history of rising and falling in the concept of economic and energy integration in the Southern Cone of South America. Despite the abundance of energy resources, and particularly the plethora of recently discovered natural gas, the region has been experiencing systematic and important energy shortages, which may threaten its economic recovery. A stronger energy integration policy would help all the partner countries to reduce energy supply risks.

    Throughout the 1990's to year 2000, energy integration, and particularly natural gas integration, was seen as a major goal in the southern cone of South America. The regional perspective for energy was related to an even more challenging objective - Latin American economic integration, which was quickly moving forward by the constitution of Mercosur, the free trade zone built by Argentina, Brazil, Uruguay and Paraguay, and also having Bolivia and Chile as special partners. Mercosur was getting stronger and becoming a successful political project. Trade conflicts existed, but they were considered normal and nobody would disagree about the viability of Mercosur. By the beginning of the 21. century, the economic integration process in South America was already advancing timidly as compared to the impetus from the beginning of 1990's. Mercosur started facing complex and almost insurmountable challenges after the numerous global financial crises (from 1998 to 2003) had affected the economic balances in the region. Energy and gas integration in South America has equally lost perspective as fast as the importance of economic integration has declined. The economic crises in the region and poor energy policies have discourage energy companies to invest. The paper presents this recent history of rise and fall in the concept of economic and energy integration in the southern cone of South America. Despite the abundance of energy resources, and particularly the plethora of recently discovered natural gas, the region has been experiencing systematic and important energy shortages, which may threaten its economic recovery. A stronger energy integration policy would help all the partner countries to reduce energy supply risks. Yet, energy (and gas) integration in the southern cone is still a complex long-term political project, which must involve all countries, but whose future perspective is unclear.

    In this paper, we present a novel visualization technique for assisting the observation and analysis of algorithmic complexity. In comparison with conventional line graphs, this new technique is not sensitive to the units of measurement, allowing multivariate data series of different physical qualities (e.g., time, space and energy) to be juxtaposed together conveniently and consistently. It supports multivariate visualization as well as uncertainty visualization. It enables users to focus on algorithm categorization by complexity classes, while reducing visual impact caused by constants and algorithmic components that are insignificant to complexity analysis. It provides an effective means for observing the algorithmic complexity of programs with a mixture of algorithms and black-box software through visualization. Through two case studies, we demonstrate the effectiveness of complexity plots in complexity analysis in research, education and application. © 2013 The Author(s) Computer Graphics Forum © 2013 The Eurographics Association and Blackwell Publishing Ltd.

    Black women bear a disproportionate burden of HIV/AIDS in North America. The purpose of this investigation was to explore Black Canadian women's perspectives on HIV risk and prevention. Four 90-minute focus groups (n=26) and six key informant interviews were conducted in Toronto with Black women of African and Caribbean descent and low socioeconomic status. Data analysis revealed a number of potent barriers to existing HIV preventive interventions: stigma, cultural disconnections, lack of engagement of Black religious institutions, and multiple intersecting forms of discrimination. Recommended HIV prevention opportunities included the Black church, mainstreaming, health care providers, and ethno-specific agencies. HIV prevention strategies for North American Black women, rather than focusing on HIV and individual risk behaviors, may benefit from a primary focus on social and structural factors (e.g., promoting gender equality, economic opportunity, women-controlled prevention technologies and combating racism in health care) thereby integrating HIV prevention into the larger context of community health and survival.

    The Secretariat of the Commission for Environmental Cooperation (CEC) was responsible for the preparation of this working paper that identifies key issues related to the evolving electricity sector and the environment. It was decided to approach the topics from an anecdotal or case-by-case basis, as the issues are very complex and the scope wide. There are ongoing discussions concerning principles, design, rules, institutional structure and consequences pertaining to the introduction of free markets in the electricity sector. Efficiency gains will be realised over time, as was argued in the paper by advocates of the competitive electricity markets in both the United States and Canada. Marginal decreases in electricity prices resulting from greater choice are also expected, in addition to the price decreases resulting from the efficiency gains. The authors warned that these benefits belong to the theoretical field, as only a small fraction of customers have switched to alternate providers in those jurisdictions where customer choice is allowed. The case of California was discussed, with its greatly increased volatility in wholesale electricity markets to illustrate how price increases have overwhelmed the expected price reductions from increased efficiency. Eight different sections were created in this paper to properly address all the issues. An overview of the current electricity sector, from the perspective of installed capacity, generation and fuel mix in North America was provided in Section One. The environmental context of electricity generation, with the focus on criteria air pollutants and non-air environmental impacts was discussed in Section Two. The various scenarios concerning electricity supply and demand, with forecasts to 2010 and 2020 were included in Section Three, in addition to a discussion related to New Generating capacity data to 2007. Possible environmental impacts of this new generating capacity was examined in Section Four, while in Section

  19. Review of the harvestfishes, genus Peprilus (Perciformes: Stromateidae), of the Atlantic coast of South America.

    Currently, seven valid species are recognized in the genus Peprilus. Found from United States to Argentina, Peprilus paru has a complex nomenclatural history, with seven junior synonyms, three from North America and four from South America. As there has been no recent research, it remains unclear whether species representatives in the north-south axis represent different populations of a single species or distinct species. By comparison of type specimens as well as a comprehensive collection of non-type specimens, this paper aims to clarify the taxonomic status of the nominal species listed as junior synonyms of Peprilus paru in the Atlantic side of South America. Based on morphological data and DNA barcoding, Peprilus crenulatus Cuvier, 1829 and P. xanthurus (Quoy & Gaimard, 1825) are resurrected, while Rhombus argentipinnis Cuvier, 1833 and Rhombus orbicularis Guichenot, 1866, are considered to be junior synonyms of P. crenulatus.

  20. Opportunities From the Digital Revolution

    Full Text Available In the 1990s, the term “online” research emerged as a new and vibrant suite of methods, focused on exploitation of sources not collected by traditional social science methods. Today, at least one part of the research life cycle is likely to be carried out “online,” from data collection through to publishing. In this article, we seek to understand emergent modes of doing and reporting qualitative research “online.” With a greater freedom now to term oneself a “researcher,” what opportunities and problems do working with online data sources bring? We explore implications of emerging requirements to submit supporting data for social science journal articles and question whether these demands might disrupt the very nature of and identity of qualitative research. Finally, we examine more recent forms of publishing and communicating research that support outputs where data play an integral role in elucidating context and enhancing the reading experience.
