    Epidemic-prone diseases have traditionally been uncommon among nomadic pastoralists as mobility allows already dispersed populations to migrate away from epidemic threats. In the Karamoja region of Uganda, nomadic pastoralists are transitioning to an increasingly settled lifestyle due to cattle raiding and associated civil insecurity. In attempts to reduce conflict in the region, the Ugandan government has instituted disarmament campaigns and encouraged sedentism in place of mobility. In Karamoja, this transition to sedentism has contributed to the emergence and reemergence of epidemic-prone diseases such as cholera, hepatitis E, yellow fever, and meningococcal meningitis. The incidence of these diseases remains difficult to measure and several challenges exist to their control. Challenges to communicable disease surveillance and control among settling nomadic pastoralists are related to nomadic mobility, remote geography, vaccination and immunity, and poor sanitation and safe water access. In addition to improving gaps in infrastructure, attracting well-trained government health workers to Karamoja and similar areas with longstanding human resource limitations is critical to address the challenges to epidemic-prone disease surveillance and control among settling nomadic pastoralists. In conjunction with government health workers, community health teams provide a sustainable method by which public health programs can be improved in the austere environments inhabited by mobile and settling pastoralists.

    Boundary effect analysis is related to border policy making in the cross-border ethnic area. The border effect literatures show that geographic boundaries have obvious impacts on economic, social and cultural relations in both sides of a nation border. Particularly in cross-border ethnic areas, each ethnic group has strong internal spatial structure relevance, and the boundary effect is more obvious. However, most of China's border areas are cross-border ethnic areas, each of border issues is unique. Under this perspective, we analyze the border effects of various boundaries can provide basis for formulating border management policies. For small scale of cross-border ethnic minority areas, how to formulate the boundary management policy is a good question to explore. This paper is demonstrated by a study of the impact of border management policies in Dehong Dai and Jingpo Autonomous Prefecture in Yunnan Province at the border area to Burma. The comparative method is used to analysis the border management policies in past 50 decades for the border area of Yunnan Province .This research aims to define trends within border policy and its influences to national security. This paper also examines Wendy Brown's liberal theory of border management policy. We found that it is not suitable for Sino-Burma border area. The conclusion is that the changes or instability of international economic and political situation has more influence to this cross-border ethnic area, and only innovative policy will be effective in cross-border ethnic area. So the border management policies should reflect the change of international context.

    Background Robust malaria vector surveillance is essential for optimally selecting and targeting vector control measures. Sixty-two vector surveillance sites were established between 2005 and 2008 by the national malaria surveillance program in China to measure Anopheles sinensis human biting rates. Using these data to determine the primary ecological drivers of malaria vector human biting rates in malaria epidemic-prone regions of China will allow better targeting of vector control resources in space and time as the country aims to eliminate malaria. Methods We analyzed data from 62 malaria surveillance sentinel sites from 2005 to 2008. Linear mixed effects models were used to identify the primary ecological drivers for Anopheles sinensis human biting rates as well as to explore the spatial-temporal variation of relevant factors at surveillance sites throughout China. Results Minimum semimonthly temperature (β = 2.99; 95% confidence interval (CI) 2.07- 3.92), enhanced vegetation index (β =1.07; 95% CI 0.11–2.03), and paddy index (the percentage of rice paddy field in the total cultivated land area of each site) (β = 0.86; 95% CI 0.17–1.56) were associated with greater An. Sinensis human biting rates, while increasing distance to the nearest river was associated with lower An. Sinensis human biting rates (β = −1.47; 95% CI −2.88, −0.06). The temporal variation (σt02=1.35) in biting rates was much larger than the spatial variation (σs02=0.83), with 19.3% of temporal variation attributable to differences in minimum temperature and enhanced vegetation index and 16.9% of spatial variance due to distance to the nearest river and the paddy index. Discussion Substantial spatial-temporal variation in An. Sinensis human biting rates exists in malaria epidemic-prone regions of China, with minimum temperature and enhanced vegetation index accounting for the greatest proportion of temporal variation and distance to nearest river and paddy index accounting for

  5. Emerging artemisinin resistance in the border areas of Thailand.

    Emergence of artemisinin resistance has been confirmed in Cambodia and the border areas of Thailand, the well-known hotspots of multidrug resistance Plasmodium falciparum. It appears to be spreading to the western border of Thailand along the Thai-Myanmar border, and will probably spread to other endemic areas of the world in the near future. This raises a serious concern on the long-term efficacy of artemisinin-based combination therapies, as these combination therapies currently constitute the last effective and most tolerable treatment for multidrug-resistant Plasmodium falciparum. Attempts have been made by a diverse array of stakeholders to prevent the emergence of new foci of artemisinin resistance, as well as to limit the spread of resistance to the original foci. The success in achieving this goal depends on effective integration of containment and surveillance programs with other malaria control measures, with support from both basic and operational research.

  6. Insect repellent plants traditional usage practices in the Ethiopian malaria epidemic-prone setting: an ethnobotanical survey

    PubMed Central

    2014-01-01

    Background The usage of insect repellent plants (IRPs) is one of the centuries-old practices in Africa. In Ethiopia, malaria remains a leading cause of morbidity and mortality, subsequently the majority of people have a tendency to apply various plants as repellents to reduce or interrupt the biting activity of insects. Accordingly, this survey was undertaken to document and evaluate knowledge and usage practices of the local inhabitants on IRPs in the malaria epidemic-prone setting of Ethiopia. Methods Ethnobotanical survey was conducted between January and May 2013. Selected 309 household members were interviewed by administering pre-tested questionnaire on knowledge and usage practices of repellent plants, in Bechobore Kebele, Jimma Zone, Ethiopia. Results Overall, 70.2% (217/309) and 91.8% (199/217) of the respondents have had ample awareness and usage practices of repellent plants, respectively. Informants cited about twenty-two plant species as repellents and also indicated that these plants are useful(85.5%), accessible(86.8%), and affordable(83.9%) too. Residents mainly applying dried leaves [93.9% (187/199)] by means of burning/smouldering [98.9% (197/199)] with the traditional charcoal stove to repel insects, primarily mosquitoes. About 52.8% (105/199) of the informants using aproximately15g of dried plant-materials every day. A Chi-square analysis shows statistically a significant link between the knowledge on repellent plants and gender as well as average monthly income although not with the age of the respondents. Nevertheless, the repellent plant usage custom was not significantly associated with gender, monthly income, and age of the informants. Conclusion Though most of the people have had an adequate awareness still a sizable faction of society suffers with deprivation of IRPs knowledge and usage practices. Therefore, this study calls for more surveys to conserve the existing indigenous knowledge and cultural practices. It could lay the first stone

    E. Vannier and P. J. Krause presented an excellent article on "Babesiosis in China, an emerging threat" in the Lancet Infectious Diseases in December 2014, which updated research on human babesiosis in China. However, a neglected and emerging issue has not been mentioned in EV & PJK's article, that is the co-infections with B. microti and P. falciparum parasites that exist in syndemic areas, spatially in the China-Myanmar border areas of Yunnan province, China. Therefore, two important issues are addressed in here, including (i) the new emerging infections with Babesia spp. which are normally ignored in malaria endemic areas due to similarities in pathogenic morphology and clinical symptoms, (ii) additional consideration on babesiosis rather than drug-resistant malaria when anti-malaria treatment for the febrile cases in clinics fails.

    The 3300 km border between Mexico and the US constitutes the geopolitical separation between an underdeveloped country on the 1 hand and 1 of the most technologically and economically powerful countries in the world on the other. The border region is characterized by the contrasts on either side of the border and by the strong interrelation between both sides. Vast streams of persons, merchandise, money, services, communications, and cultural influences flow from 1 side to the other. The border region as a seat of population has a recent history. The border was defined in near current form only in the mid-19th century, when the expansionist tendencies of the US encountered a vast area of very sparse population. In 1900, the principal localities of the border zone had only about 39,000 inhabitants, of whom fewer than 5000 lived west of Ciudad Juarez. Between 1910-20, the population of the border region increased from 53,000 to 96,000 as a result of migrants fleeing the ravages of the revolution. The population of the border region was estimated at 3.826 million in 1988, resulting from rates of growth above Mexico's national average. Settlement in the area has depended on events and conditions in Mexico and on such US occurrences as Prohibition, the Great Depression, the 2nd World War, the Bracero program, and the Program of Border Industrialization. 82% of the border population lives in urban zones, partly because of lack of water. 80% of the urban population is concentrated in 6 cities, Juarez, Tijuana, Mexicali, Nuevo Laredo, Reynosa, and Matamoros. Much of the population of the 6 cities is composed of persons born elsewhere. The border area also has a large floating population of undocumented migrants in transit to or from the US. The high rates of urbanization and of binational interaction are reflected in demographic dynamics. In 1979, 71% of women in union in the border area vs 54% in the rest of Mexico had used contraception, and the infant mortality rate was

  16. Design considerations for intrusion detection wide-area surveillance radars for perimeters and borders

    2009-05-01

    Ground Surveillance Radars (GSRs) can build a virtual wall around facilities or on a border. They provide operators and agents with much more time to assess, prioritize and apprehend intruders than a traditional fence system. The extra response time is one of the important features of the wide area surveillance concept, along with added benefits for both the operators and the response teams. These are described in detail in the paper. But all GSRs are not alike. There are two primary GSR technologies - Frequency Modulated Continuous Wave (FMCW) and Pulse Doppler. Most pulse Doppler radars are derivatives of legacy military battlefield radar technology being applied for wide area surveillance, while a new generation of FMCW radar technology has been developed for this new type of surveillance, applied to high value site security, airports, military bases, ports and borders. The purpose of this paper is to explore the benefits of each type of radar for the wide area application.

    Factors associated with CES-D depression among Mexican Americans living on and off the U.S.-Mexico border are examined. Data are from two studies of Mexican American adults. The Border Survey conducted face-to-face interviews in urban U.S.-Mexico border counties of California, Arizona, New Mexico, and Texas (N = 1307). The non-border HABLAS survey conducted face-to-face interviews in Houston, Los Angeles, New York, Philadelphia, and Miami (N = 1288). Both surveys used a multistage cluster sample design with response rates of 67 and 76 %, respectively. The multivariate analysis showed that border residence and higher perceived neighborhood collective efficacy were protective for depression among men. Among men, lower education, unemployment, increased weekly drinking, and poor health status were associated with depression. Among women, alcohol-related problems and poorer health status were also associated with depression. Further examinations of how neighborhood perceptions vary by gender and how these perceptions influence the likelihood of depression are warranted. PMID:26137982

    IEEE 802.15.4 based Wireless Personal Area Networks (WPANs) are envisioned to play a vital role in the application centric ubiquitous networks. In IEEE802.15.4 networks, the use of non-interfering logical channels in multiple PANs, operating in a Personal Operating Space (POS) ensures to control the scope of PAN-directed broadcasts, reduce received energy per PAN device, and minimize interference at the physical layer. At the downside the inter-PAN communication is not possible with this setup as PANs in the same region remain unaware of each other's presence. This situation hinders sharing information of common interest amongst PANs and accessing infrastructure networks hopping through multiple PANs. In this paper, we present a comprehensive architecture enables neighboring PANs to communicate by diffusing into each other through border nodes. The basic idea is to time share logical channels to perform a gating operation by border nodes. Our contribution includes detection of border nodes, discovery of neighboring PAN(s), a common channel based gating protocol, interest diffusion and inter-PAN data transfer. We mathematically analyze the proposed architecture and carry out simulations in Network Simulator (ns2) for performance evaluation. Our simulations show that the proposed architecture gives optimal performance when multiple border nodes are able to perform gating. PMID:23961343

    The Yuma Sector Border Patrol Area is a high flux lighting application in a high temperature environment, presenting a formidable challenge for light-emitting diodes (LEDs). This retrofit is an Energy Savings Performance Contract ENABLE project under the U.S. Department of Energy (DOE) Federal Energy Management Program. If high flux LED technology performs well in a region with high ambient temperature and solar radiation, it can perform well in most outdoor environments. The design process for the Yuma retrofit has already provided valuable knowledge to CBP and DOE. The LED lighting system selected for the retrofit is expected to reduce energy consumption 69% compared to the incumbent quartz metal halide (QMH) lighting system. If the LED lighting system is installed, GATEWAY will continue to document and disseminate information regarding the installation and long-term performance so that others may also gain valuable knowledge from the Yuma Sector Border Patrol Area lighting retrofit.

    The Mexico-United States border area has become an increasingly important region due to its commercial, industrial and urban growth. As a result, environmental concerns have risen. Treaties like the North American Free Trade Agreement (NAFTA) have further motivated the development of environmental impact assessment in the area. Of particular concern are air quality, and how the activities on both sides of the border contribute to its degradation. This paper presents results of applying a three-dimensional photochemical airshed model to study air pollution dynamics along the Mexico-United States border. In addition, studies were conducted to assess how size resolution impacts the model performance. The model performed within acceptable statistic limits using 12.5 x 12.5 km{sup 2} grid cells, and the benefits using finer grids were limited. Results were further used to assess the influence of grid-cell size on the modeling of control strategies, where coarser grids lead to significant loss of information.

    Currently, there is a trend of an increasing number of Plasmodium vivaxmalaria cases in China that are imported across its Southeast Asia border, especially in the China-Myanmar border area (CMB). To date, little is known about the genetic diversity of P. vivax in this region. In this paper, we report the first genome sequencing of a P. vivaxisolate (CMB-1) from a vivax malaria patient in CMB. The sequencing data were aligned onto 96.43% of the P. vivax Salvador I reference strain (Sal I) genome with 7.84-fold coverage as well as onto 98.32% of 14 Sal I chromosomes. Using the de novo assembly approach, we generated 8,541 scaffolds and assembled a total of 27.1 Mb of sequence into CMB-1 scaffolds. Furthermore, we identified all 295 known virgenes, which is the largest subtelomeric multigene family in malaria parasites. These results provide an important foundation for further research onP. vivax population genetics. PMID:26517664

    Human-elephant conflict is a major problem leading to crop damage, human death and injuries caused by elephants, and elephants being killed by humans. In this paper, we propose an automated unsupervised elephant image detection system (EIDS) as a solution to human-elephant conflict in the context of elephant conservation. The elephant's image is captured in the forest border areas and is sent to a base station via an RF network. The received image is decomposed using Haar wavelet to obtain multilevel wavelet coefficients, with which we perform image feature extraction and similarity match between the elephant query image and the database image using image vision algorithms. A GSM message is sent to the forest officials indicating that an elephant has been detected in the forest border and is approaching human habitat. We propose an optimized distance metric to improve the image retrieval time from the database. We compare the optimized distance metric with the popular Euclidean and Manhattan distance methods. The proposed optimized distance metric retrieves more images with lesser retrieval time than the other distance metrics which makes the optimized distance method more efficient and reliable.

    Creation of pressure-area relationships (loops) with automated border detection (ABD) involves correction for the variable inherent delay in the ABD signal relative to the pressure recording. This article summarizes (1) the results of in vitro experiments performed to define the range of, and factors that might influence, the ABD delay; (2) the difficulties encountered in evaluating a thin-walled structure like the left atrium in the dog model; and (3) the solutions to some of the difficulties found. The in vitro experiments showed that the ABD delay relative to high-fidelity pressure recordings ranges from 20 to 34 msec and 35 to 57 msec at echocardiographic frame rates of 60/sec and 33/sec, respectively. The delay was not influenced significantly by the type of transducer used, distance from the target area, or size of the target area. The delay in the ABD signal, relative to the echocardiographic image, ranges from nil to less than one frame duration, whereas it is delayed one to two frame durations relative to the electrocardiogram processed by the imaging system. In the dog model, inclusion of even small areas outside the left atrium rendered curves with apparent physiologic contour but inappropriately long delays of 90 to 130 msec. To exclude areas outside the left atrial cavity, time-gain compensation and lateral gain compensation were used much more extensively than during left ventricular ABD recording. By changing the type of sonomicrometers used in our experiments, we were able to record simultaneously ABD and ultrasonic crystal data. However, both spontaneous contrast originating from a right-sided heart bypass pump and electronic noise from the eletrocautery severely interferred with ABD recording. PMID:9417210

    2008-12-01

    The aim of this study was to assess the potential for coexistence between rural people (living adjacent to a protected area) and predators (from the same area) ranging onto communal land. Ninety members of local communities bordering Manyeleti Game Reserve, which is contiguous with Kruger National Park, South Africa were interviewed. Respondents expressed diverging attitudes toward predators, which were more favorable among participants with higher education. Negative views were particularly due to fear of human and livestock losses, especially to lions, Panthera leo. Lions were thought to be the most abundant predator both within and outside the reserve. Lions were also the best known predator and were most often held responsible for killing livestock. Despite these livestock losses and a lack of conservation education, most participants voiced favorable opinions about large carnivore conservation, as predators were considered an integral part of the respondents’ natural heritage. Thanks to this cultural tolerance and also because of a largely accepted management policy regarding predator control, large carnivores and people can coexist in the vicinity of Kruger National Park.

    The United States - Mexico border area faces the challenge of integrating aspects of its binational physical boundaries to form a unified or, at least, compatible natural resource management plan. Specified geospatial components such as stream drainages, mineral occurrences, vegetation, wildlife, and land-use can be analyzed in terms of their overlapping impacts upon one another. Watersheds have been utilized as a basic unit in resource analysis because they contain components that are interrelated and can be viewed as a single interactive ecological system. In developing and analyzing critical regional natural resource databases, the Environmental Protection Agency (EPA) and other federal and non-governmental agencies have adopted a ?watershed by watershed? approach to dealing with such complicated issues as ecosystem health, natural resource use, urban growth, and pollutant transport within hydrologic systems. These watersheds can facilitate the delineation of both large scale and locally important hydrologic systems and urban management parameters necessary for sustainable, diversified land-use. The twin border cities area of Nogales, Sonora and Nogales, Arizona, provide the ideal setting to demonstrate the utility and application of a complete, cross-border, geographic information systems (GIS) based, watershed analysis in the characterization of a wide range of natural resource as well as urban features and their interactions. In addition to the delineation of a unified, cross-border watershed, the database contains sewer/water line locations and status, well locations, geology, hydrology, topography, soils, geomorphology, and vegetation data, as well as remotely sensed imagery. This report is preliminary and part of an ongoing project to develop a GIS database that will be widely accessible to the general public, researchers, and the local land management community with a broad range of application and utility.

    Cystic Echinococcosis is a major public health issue. Immunodiagnostic techniques based on the identification of parasite antigens in dog dry faeces have been developed as alternatives for the surveillance of canine Echinococcosis. The environmental conditions favouring the parasite cycle were met in the border of La Quiaca-Villazón, given the presence of definitive (dog) and intermediate hosts (sheep and goats). The most important activity in La Puna is sheep and goat rearing; slaughtering is carried out almost exclusively in the field by sheep's owners, and preventive health measures do not apply. The aim of this study was to determine the presence of dogs parasitized by Echinococcus granulosus in this border region. A hundred and sixty eight (168) stool specimens were collected during 2006. La Quiaca samples were taken from the following selected areas: the semi-rural area of Barrios, the rural areas of Santa Catalina, Yavi Chico, El Portillo, Pumahuasi and Cara Cara and the urban area of La Quiaca; selected urban areas in Villazón and the semi-rural area of Ojo de Agua, Lampaya and Matancillas. The samples were analyzed by copro-ELISA -Western blot test. The cities of San Francisco and Barrios had a prevalence of 14.3% and 6.7%, respectively. A prevalence of 3.4% was observed in the urban area of Villazón, which indicates that dogs become infected in the rural areas and bring the risk into the city. Lampaya showed a prevalence of 30%. These findings suggest the need to implement strategies for the control of hydatidosis, both in urban and rural areas to avoid the increase and spread of Echinococcosis in the region. PMID:24165137

    The access to an ever increasing amount of information in the modern world gave rise to the development of many quantitative indicators about urban regions in the globe. Therefore, there is a growing need for a precise definition of how to delimit urban regions, so as to allow proper respective characterization and modeling. Here we present a straightforward methodology to automatically detect urban region borders around a single seed point. The method is based on a diffusion process having street crossings and terminations as source points. We exemplify the potential of the methodology by characterizing the geometry and topology of 21 urban regions obtained from 8 distinct countries. The geometry is studied by employing the lacunarity measurement, which is associated to the regularity of holes contained in a pattern. The topology is analyzed by associating the betweenness centrality of the streets with their respective class, such as motorway or residential, obtained from a database.

    Cadmium concentrations ([Cd]) were measured in samples from the water column of the coastal upwelling zone adjacent to the California - Mexico border. Temperature and nutrient distributions showed an intense upwelling event during our sampling. Lowest [Cd] were found at locations offshore (50 km) (0·03-0·058 nM), whereas the maximum concentrations were found inshore (0·14-0·166 nM). Both nutrients and [Cd] were enriched in coastal waters. Our inshore [Cd] values are about 25% of those reported for waters off central California. This is possibly due to the intrusion of oligotrophic waters from the eastern edge of the North Pacific Central Gyre to the Southern California Bight. Multivariate analysis indicates that high [Cd]s were associated with high phytoplankton biomass, nutrients and low temperature. Our data present no evidence of a [Cd] gradient due to the San Diego and Tijuana sewage discharges, which indicates that they maintain a very local effect.

    Shale gas development, including drilling and hydraulic fracturing, is rapidly increasing throughout the United States and, indeed, the rest of the world. Systematic surveys of water quality both pre- and post drilling/production are sparse. To examine the impacts of shale gas production on water quality, pilot studies are being conducted in adjacent counties of western NY (Chemung, Tioga, Broome, and Delaware) and northern PA (Bradford, Susquehanna, and Tioga). These 7 counties along the border of NY and PA share similar geology and demographic compositions and have been identified as a key area to develop shale gas with the key difference that active fracking is occurring in PA but there is no fracking yet in NY due to the current moratorium in that state. Measurements include a suite of volatile organic compounds (VOCs), major and trace elements, methane and its stable isotopes, noble gases and tritium for dating purposes, and the primary radioactive elements of potential concern, radon and radium. We found elevated methane levels on both sides of the border, and some wells show elemental fingerprints characteristic for shale fluids. Field observations at several wells near drill sites in PA suggested elevated levels of organics, possibly from hydraulic fracturing activities. The full suite of lab analyses is currently ongoing and can be used to further characterize sources of these organics.

    The weight wilderness study areas are Orderville Canyon, North Fork Virgin River, Deep Creek, Goose Creek Canyon, Beartrap Canyon, La Verkin Creek Canyon, Taylor Creek Canyon, and Red Butte. The study areas are located on the Kolob Terrace in the canyonlands of southwest Utah. Jurassic sedimentary rocks are exposed in all of the study areas; Cretaceous rocks are present in three of the study areas. The Orderville Canyon, North Fork Virgin River, and Deep Creek study areas have inferred subeconomic resources of gypsum. Inferred subeconomic resources of common-variety sandstone occur in all of the study areas. Inferred subeconomic resources of limestone occur in all but the Red Butte study area. All of the study areas have a moderate potential for oil and gas and a low potential for all metals (including silver and uranium) and geothermal sources.

    Little is known about circulation of influenza and other respiratory viruses in remote populations along the Thai-Cambodia border in western Cambodia. We screened 586 outpatients (median age 5, range 1-77) presenting with influenza-like-illness (ILI) at 4 sentinel sites in western Cambodia between May 2010 and December 2012. Real-time reverse transcriptase (rRT) PCR for influenza was performed on combined nasal and throat specimens followed by viral culture, antigenic analysis, antiviral susceptibility testing and full genome sequencing for phylogenetic analysis. ILI-specimens negative for influenza were cultured, followed by rRT-PCR for enterovirus and rhinovirus (EV/RV) and EV71. Influenza was found in 168 cases (29%) and occurred almost exclusively in the rainy season from June to November. Isolated influenza strains had close antigenic and phylogenetic relationships, matching vaccine and circulating strains found elsewhere in Cambodia. Influenza vaccination coverage was low (<20%). Western Cambodian H1N1(2009) isolate genomes were more closely related to 10 earlier Cambodia isolates (94.4% genome conservation) than to 13 Thai isolates (75.9% genome conservation), despite sharing the majority of the amino acid changes with the Thai references. Most genes showed signatures of purifying selection. Viral culture detected only adenovirus (5.7%) and parainfluenza virus (3.8%), while non-polio enteroviruses (10.3%) were detected among 164 culture-negative samples including coxsackievirus A4, A6, A8, A9, A12, B3, B4 and echovirus E6 and E9 using nested RT-PCR methods. A single specimen of EV71 was found. Despite proximity to Thailand, influenza epidemiology of these western Cambodian isolates followed patterns observed elsewhere in Cambodia, continuing to support current vaccine and treatment recommendations from the Cambodian National Influenza Center. Amino acid mutations at non-epitope sites, particularly hemagglutinin genes, require further investigation in light

    Data from the 1991 Argentine census indicate that migrants from neighboring countries at that date were maintaining patterns of entry into the labor force of Buenos Aires consistent with past tendencies. Migrants tended to be employed in less skilled manufacturing industries, construction, commerce, and domestic work, often filling positions rejected by the native population because of low wages and poor working conditions. Profound changes in the Argentine economy since 1991 have included rising unemployment and underemployment and a loss of productive jobs in industry and construction. A comparison of the occupational structure of migrants from neighboring countries and of the total population for the years 1980, 1991, and 1996 demonstrates that important changes in sectorial employment have occurred among both the native and immigrant populations, with the immigrant population increasingly relegated to ever smaller sectors of the labor market offering less attractive employment. Nearly half of the 841,697 persons immigrating in 1991 from countries bordering Argentina settled in the Buenos Aires metropolitan region, comprising 42.8% of foreigners in the metropolitan area and 3.7% of the total regional population. Of the population from border countries residing in Buenos Aires, 43% are Paraguayan, 28% Uruguayan, 15% Bolivian, 12% Chilean, and 2% Brazilian. The unemployment rate in Buenos Aires fluctuated between 4% and 6% during 1974-92, but it rose to 10.6% in 1993 and then to 18% in 1996. The underemployment rate rose from 4.6% in 1983 to 8.2% in 1993 and 12.6% in 1996. PMID:12321683

    Deletion of the Plasmodium falciparum histidine-rich protein 2 (pfhrp2) gene may affect the performance of PfHRP2-based rapid diagnostic tests (RDTs). Here we investigated the genetic diversity of the pfhrp2 gene in clinical parasite isolates collected in recent years from the China-Myanmar border area. Deletion of pfhrp2 has been identified in 4 out of 97 parasite isolates. Sequencing of the pfhrp2 exon 2 from 67 isolates revealed a high level of genetic diversity in pfhrp2, which is reflected in the presence of many repeat types and their variants, as well as variable copy numbers and different arrangements of these repeats in parasite isolates. In addition, we observed pfhrp3 deletion in three of the four parasites harboring pfhrp2 deletion, suggesting of double deletions of both genes in these three isolates. Analysis of two cases, which were P. falciparum-positive by microscopy and PCR but failed by two PfHRP2-based RDTs, did not find pfhrp2 deletion. Further correlational studies of pfhrp2 polymorphisms with detection sensitivity are needed to identify factors influencing the performance of RDTs in malaria-endemic areas. PMID:26297799

    3-D Vp and Vp/Vs structure of the geodynamically active NW Bohemia/Vogtland area, located at the border region between Germany and Czech republic, has been determined from local earthquake tomography using 543 earthquakes which have been recorded during 2000 to 2010. This region is known for the occurrence of earthquake swarms that are supposed to be triggered by fluid upwelling in the crust, although fluid behaviour and migration paths in the subsurface of NW Bohemia is still poorly known. The events used in this study were selected based on a minimum 12 P and S phase observations and an azimuthal gap less than 160º. This data set is employed to derive a minimum 1-D velocity model and to relocate the hypocenters. The minimum 1-D velocity model is then used as an initial model in non-linear inversion to derive 3-D P-velocity and Vp/Vs ratio. Using synthetic tests, it can be shown that a high resolution is obtained in the central part of the studied region with the given source and receiver configuration. Two branches of high Vp/Vs ratio anomalies have been detected above the swarm quakes' focal zone. These anomalies support the existence of two main fluid passages toward Bad Brambach and Bublak moffette. Another interesting result is a high Vp/Vs line-like anomaly along Mariánské Lázně fault where most of the swarm quakes occur, which could be due to a fluid saturated area around the cracked zone of the fault plain. Hypocenters in the swarm region are located in a low Vp and Vp/Vs anomaly. The correlation between the detected Vp and Vp/Vs anomalies and the location of earthquake swarm suggests a model in which CO2 as part of magmatic fluids exist in a vast area beneath NW Bohemia and frequently migrate up to the surface.

    To investigate the genetic diversity of the Plasmodium falciparum apical membrane antigen 1 (PfAMA1) gene in Southeast Asia, we determined PfAMA1 sequences from 135 field isolates collected from the China-Myanmar border area and compared them with 956 publically available PfAMA1 sequences from seven global P. falciparum populations. This analysis revealed high genetic diversity of PfAMA1 in global P. falciparum populations with a total of 229 haplotypes identified. The genetic diversity of PfAMA1 gene from the China-Myanmar border is not evenly distributed in the different domains of this gene. Sequence diversity in PfAMA1 from the China-Myanmar border is lower than that observed in Thai, African and Oceanian populations, but higher than that in the South American population. This appeared to correlate well with the levels of endemicity of different malaria-endemic regions, where hyperendemic regions favor genetic cross of the parasite isolates and generation of higher genetic diversity. Neutrality tests show significant departure from neutrality in the entire ectodomain and Domain I of PfAMA1 in the China-Myanmar border parasite population. We found evidence supporting a substantial continent-wise genetic structure among P. falciparum populations, with the highest genetic differentiation detected between the China-Myanmar border and the South American populations. Whereas no alleles were unique to a specific region, there were considerable geographical differences in major alleles and their frequencies, highlighting further necessity to include more PfAMA1 alleles in vaccine designs.

    Pakistan and Afghanistan share a long uncontrolled border with extensive population movement on both sides. Wild poliovirus transmission has never been interrupted in this block due to war against terrorism, poor public health infrastructure, misconceptions about polio vaccines and inadequate immunization activities. All these issues complicate the eradication operations and reinforce the complexity of wiping out poliomyelitis from this region. This study illustrates the origins and routes of cross-border wild poliovirus type 1 (WPV1) transmission during 2010–2012 between Pakistan and Afghanistan. Sequence analyses were conducted based on complete VP1 capsid protein sequences for WPV1 study strains to determine the origin of poliovirus genetic lineages and their evolutionary relationships. Phylogenetic tree was constructed from VP1 gene sequences applying Maximum Likelihood method using Kimura 2- parameter model in MEGA program v 5.0. A total of 72 (14.3%) out of 502 wild-type 1 polioviruses were found circulating in border areas of both countries during 2010–2012. Molecular phylogenetic analysis classified these strains in to two sub-genotypes with four clusters and 18 lineages. Genetic data confirmed that the most of WPV1 lineages (12; 66.6%) were transmitted from Pakistan to Afghanistan. However, the genetic diversity was significantly reduced during 2012 as most of the lineages were completely eliminated. In conclusion, Pakistan-Afghanistan block has emerged as a single poliovirus reservoir sharing the multiple poliovirus lineages due to uncontrolled movement of people across the borders between two countries. If it is neglected, it can jeopardize the extensive global efforts done so-far to eradicate the poliovirus infection. Our data will be helpful to devise the preventive strategies for effective control of wild poliovirus transmission in this region. PMID:25229826

    With the increasing demand of natural rubber products in the world market, rubber plantations have dramatically expanded into northern areas of tropical and subtropical zones in Southeast Asia, which have been affecting ecosystem services and human wellbeing. In the cross-border area of five countries (China, Vietnam, Laos, Thailand, and Myanmar), the rubber plantation dynamics varied substantially due to the differences in socioeconomic conditions from local to national scales. However, no spatially explicit information available for this region due to very limited efforts in research and monitoring. Our previous studies have proposed a phenology- and multisensor-based approach to map rubber plantation according to its deciduous feature; however, it is still uncertain that whether the approach can be used for the cross-border area. In this study, we aim to assess the potential of the previous algorithm in the study area by integrating a base forest map from 25-m phase-array L-band synthetic aperture radar (PALSAR) orthorectified mosaic imagery and defoliation information from all the available 30-m Landsat archive imagery. Furthermore, we would compare the changes in the rubber plantation pattern in the five countries from 2007 to 2014. The rubber plantation dynamics in individual countries will be analyzed by considering policies and other factors in different countries. The study would provide valuable information for a broad scientific community (e.g., carbon cycle, biodiversity) and forest management departments.

    The rise of artemisinin resistant Plasmodium falciparum along the Thai-Cambodian border is an urgent public health threat. We conducted an employer-based survey of migrant workers in two provinces in Thailand along the Thai-Cambodian border to explore socio-economic conditions, bednet ownership, and parasite prevalence among migrant workers. Five thousand three hundred seventy-one migrant workers were enrolled in this study; 56.9% were male. Cambodians comprised 69.0%, migrants from Myanmar comprised 20.7% and Mon and Laotian comprised 10.3%. Short term (< 6 months) Cambodian migrants, primarily located in Chanthaburi Province, typically work in orchards or on cassava farms. The majority did not speak Thai and bednet ownership was low. The only cases of malaria, all P. vivax, were found in Chanthaburi. Migrants in Trat Province were primarily long-term residents (> 6 months) from Cambodia and Myanmar and were engaged in rubber tapping, fisheries and domestic work. Bednet ownership and oral Thai fluency were higher, though Thai literacy remained low. Migrants from Myanmar had higher mother tongue literacy than migrants from Cambodia. The low oral Thai fluency and literacy rates suggest a Behavior Change Communication (BCC) package for Cambodian migrants should be developed in the Cambodian language. The low parasite prevalence and absence of P. falciparum in this study are encouraging signs in the fight against artemisinin resistance in eastern Thailand. PMID:23082578

    Background: Imported malaria is a major threat to neighboring malaria-eliminating countries such as P.R. China and is difficult to monitor. A molecular survey of febrile patients with a history of traveling abroad along the Myanmar-China endemic border areas from January 2008 to August 2012 was carried out. The rates of infection with species of Plasmodium and compliance of microscopy diagnosis with nested PCR (Polymerase Chain Reaction) results were calculated. Results: Plasmodium genus-specific nested PCR confirmed that 384 cases were positive. Further species-specific nested PCR showed that the rate of Plasmodium vivax infection was 55% (213/384); that of Plasmodium falciparum was 21% (81/384) and 17% (67/384) of cases were co-infection cases of P. vivax and P. falciparum; the remaining 6% (23/384) of cases were caused by other species, such as Plasmodium ovale, P. malaria, P. knowlesi or mixed infections of Plasmodium. In total there was 13% (50/384) false microscopy diagnosis including 6% (22/384) error in species diagnosis and 7% (28/384) undiagnosed cases in co-infection or low parasitemia malaria cases. Conclusions: This study indicates that there are considerable numbers of malaria cases in the China-Myanmar endemic border areas that remain undiagnosed or misdiagnosed by microscopy, especially in low-level and/or complex co-infection cases. It is urgent to develop accurate rapid diagnostic tests and apply PCR confirmation for efficient surveillance. PMID:24954235

    Background Aedes albopictus, the Asian tiger mosquito, originates from the tropical and subtropical regions of Southeast Asia. Over the recent decades it has been passively spread across the globe, primarily through the used tyre trade and passive transportation along major traffic routes. A. albopictus is a proven vector for many arboviruses, most notably chikungunya and dengue, with recent outbreaks also in continental Europe. In southern Switzerland, in the Canton of Ticino A. albopictus was spotted for the first time in 2003. Since then the local authorities have implemented a control programme based on larval source reduction. Despite these efforts, mosquito densities have increased over the last decade, casting doubts on the effectiveness of such larval control programmes. Methodology/Principal Findings The Italian communities just across the Swiss-Italian border lack a control programme. This motivated us to compare the intervention and the non-intervention areas side by side in an attempt to find evidence for, or against, the effectiveness of larval A. albopictus control. Using ovitraps and a randomised sampling scheme, we examined the seasonal and spatial abundance of A. albopictus in sylvatic and urban environments across the Swiss-Italian border in 2012 and 2013. In the urban environments of the non-intervention area, egg densities were 2.26 times higher as compared to the intervention area. In the sylvatic environments, as compared to the urban environments, egg densities were 36% in the intervention area and 18% in the non-intervention area. Conclusions/Significance Though alternative explanations are also valid, the results support the hypothesis that the Ticino intervention programme does have an impact. At the same time the data also suggest that current larval interventions fall short in gaining full control over the mosquito, calling for the evaluation of additional, or alternative, approaches. Ideally, these should also consider inclusion of the

    2014-01-01

    Background Mato Grosso do Sul has been undergoing a process of urbanization which results in loss of native vegetation. This withdrawal makes vectors of man and domestic animals closer, causing changes in the epidemiology of diseases such as American Visceral Leishmaniasis. The aim of the study was to evaluate the phlebotomine fauna and environmental issues related to the transmission of AVL in Ponta Porã, Mato Grosso do Sul, between 2009 and 2010. Methods Vegetation of the urban area was evaluated by Normalized Difference Vegetation Index (NDVI), Normalized Difference Water Index (NDWI) and Soil Adjusted Vegetation Index (SAVI). Results The results showed that the phlebotomine fauna of the city consists of five species, especially Lutzomyia longipalpis (Lutz and Neiva, 1912), the vector of Leishmania (Leishmania) infantum. Predominance of males was observed. The insects were captured in greater quantity in the intradomicile. Lu. longipalpis was the most frequent and abundant species, present throughout the year, with a peak population after the rainy season. Vectors can be found in high amounts in forest and disturbed environments. Conclusions The finding of Lu. longipalpis in regions with little vegetation and humidity suggests that the species is adapted to different sorts of environmental conditions, demonstrating its close association with man and the environment it inhabits. The tourist feature of Ponta Porã reinforces its epidemiological importance as a vulnerable city.

    This article presents results of research concerning tourist infrastructure in some districts located in the Bug river valley, in the context of protected areas. The territory examined includes 9 rural districts and 2 towns in the immediate neighborhood of the river. These administrative units are characterized by great natural value. Their total area is 687,7 km2 that makes 6,7% of the whole Lublin voivodship. On the other hand, the share of protected areas (without Natura 2000) is twice as high - 11,1%. Protected areas makes 37,6% of the territory under study. In some units, share of protected areas is very high: Dubienka - 72%, Horodło - 69,5%. In 2009 in the region examined there were 48 objects of collective accommodation - 16,8% of total number in the voivodship. 83,6% of all objects were situated in Włodawa. Characteristic feature of accommodation is seasonality. There are only 7 objects that functions the whole year and year-round lodging places (280) makes barely 9,3% of the totality. Comparing tourist management with presence of areas of the highest natural values, one can see strong correlation between these two indexes only in rural unit - Włodawa, located within the borders of Biosphere Reserves "Polesie Zachodnie" (West Polesie) In case of other units such a interdependance does not exist. On the contrary, there is opposite relation. In Dołhobyczów, Mircze, Horodło, where apart from areas of Natura 2000, in the Bug river valley landscapes protected areas and landscapes parks were created, tourist infrastructure is insignificant or even does not exist. The existence of large protected areas and natural value make it possible to develop various forms of environmentally friendly tourism - tourism qualified, especially fishing and canoeing, hiking, biking, nature education tourism. Tourist service centers should be located outside the valley. Due to the high natural values, caution is advisable to adapt the area for tourism. Such decisions should

    SUMMARY In this study, Leishmaniaspecies were identified by Polymerase Chain Reaction (PCR). The epidemiology of patients suspected of having American Cutaneous Leishmaniasis in the municipality of Assis Brasil, Acre State, located in the Brazil/Peru/Bolivia triborder was also investigated. By PCR, the DNA of Leishmaniawas detected in 100% of the cases (37 samples) and a PCR-Restriction Fragment Length Polymorphism (RFLP) of the hsp 70gene identified the species in 32 samples: Leishmania (Viannia) braziliensis (65.6%) , L. (V.) shawi (28.1%) , L. (V.) guyanensis (3.1%) and mixed infection L. (V.) guyanensis and L. (Leishmania) amazonensis (3.1%)This is the first report of L. (V.) shawiand L. (L.) amazonensis in Acre. The two predominant species were found in patients living in urban and rural areas. Most cases were found in males living in rural areas for at least three years and involved in rural work. This suggests, in most cases, a possible transmission of the disease from a rural/forest source, although some patients had not engaged in activities associated with permanence in forestall areas, which indicate a possible sandflies adaptation to the periurban setting.

    Examination of border-specific characteristics such as trans-border mobility and transborder health service illuminates the heterogeneity of border Hispanics and may provide greater insight toward understanding differential health behaviors and status among these populations. In this study, we create a descriptive profile of the concept of trans-border mobility by exploring the relationship between mobility status and a series of demographic, economic and socio-cultural characteristics among mobile and non-mobile Hispanics living in the El Paso-Juarez border region. Using a two-stage stratified random sampling design, bilingual interviewers collected survey data from border residents (n = 1,002). Findings show that significant economic, cultural, and behavioral differences exist between mobile and non-mobile respondents. While non-mobile respondents were found to have higher social economic status than their mobile counterparts, mobility across the border was found to offer less acculturated and poorer Hispanics access to alternative sources of health care and other services.

    In order to better control fruit flies (Diptera: Tephritidae) attacking Cucurbitaceae on Reunion Island (21°6 S/ 55°36 E), biological characteristics (seasonal fluctuation, relative abundance, sex ratio) of communities roosting in corn borders were investigated. The study was conducted in austral summer across a range of altitudes (750–1150 m) corresponding to the main areas of cucurbit cropping. Living adults were recorded roosting on corn planted within or around cucurbit fields. Results showed a high variability in seasonal fluctuation of populations according to local conditions. Bactrocera Cucurbitae (Coquillett) (Diptera: Tephritidae) was the least abundant species (27%) compared to Dacus ciliatus Loew (36%) and Dacus demmerezi Bezzi (37%). Relative abundance of B. Cucurbitae was lowest (< 18%) in high altitude sites (above 1000 m), where D. demmerezi was the most prevalent species (> 56%). Dacus ciliatus showed variable relative abundance (from 18 to 51%) depending on the experimental design (varying in location and in year). Sex ratio was also very variable from one species to another and from one experimental design to another. PMID:22958393

    Objectives MRSA poses a considerable public health threat to the community. The objectives of this study were to assess the prevalence of MRSA carriage and determine factors that were associated with MRSA carriage among outpatients who had used antibiotics in the previous three months and who lived in a high-density livestock farming area along the Dutch-German border. Methods Cross-sectional prevalence study carried out between November 2011 and June 2012. Nasal swabs and questionnaires were collected in patients (>4 years) who had used antibiotics in the previous three months from twelve Dutch General Practitioners (GPs), seven German GPs and two German outpatient urologists. To assess nasal carriage, swabs were analyzed using selective MRSA agars after broth enrichment. MRSA positive samples were spa typed. Results Data were collected from 513 GP outpatients in the Netherlands, 261 GP outpatients in Germany and 200 urologist outpatients in Germany. The overall prevalence of MRSA carriage was 0.8%, 1.1% and 2.0%, respectively. In the GP outpatient populations, the prevalence was similar in both countries (0.8% and 1.1%, respectively, p = 0.879), all spa types were indicative for livestock-associated MRSA (4xt011 in the Netherlands; 2xt034 and t011 in Germany) and being a farmer, living on or near (<5km) to a farm were associated with MRSA carriage. In the urologist outpatient population, the prevalence was higher (2.0%), all spa types were indicative for healthcare-associated MRSA (t068, t032, t003, t10231) and being a farmer, living on or near to a farm were factors not associated with MRSA carriage. Conclusions The prevalence of MRSA carriage in these community outpatient populations along the Dutch-German border was low. There were striking similarities in livestock-associated MRSA carriage and clonal spread in the outpatient populations seeing their GP in both countries. In contrast, urologist outpatients in Germany were colonized with spa types indicative of

    BACKGROUND This paper examines the prevalence, the symptom profile, and the drinking and sociodemographic predictors of current (past 12 month) DSM-IV alcohol abuse and dependence among Mexican Americans living along the U.S.-Mexico border and those living in metropolitan areas away from the border. METHODS Respondents in the non-border areas (primarily Houston and Los Angeles) constitute a multistage probability sample (N=1,288) of these areas, interviewed as part of the 2006 Hispanic Americans Baseline Alcohol Survey (HABLAS). Respondents in the border area (N=1,307) constitute a household probability sample of Mexican Americans living on the border. In both surveys, data were collected during computer assisted interviews conducted in respondents’ homes. The HABLAS and the border sample response rates were 76% and 67%, respectively. RESULTS Although bivariate analyses revealed no overall differences between border and non-border locations, (negative) age trends were more pronounced on the border for male abuse and for dependence among both genders. Among females aged 18–29, border residence was linked to significantly higher rates of dependence. In multivariable analyses, the prevalence of male abuse declined more rapidly with age on the border than off the border. Other unique predictors of male abuse were Jewish/other religion and weekly volume of alcohol consumption. Being married or out of the workforce, attaining a higher education, no religious preference, and weekly volume uniquely predicted female dependence. Age and weekly volume uniquely predicted male dependence. CONCLUSIONS The prevalence of alcohol use disorders among Mexican Americans on and off the U.S.-Mexico border largely mirrors previously documented patterns of alcohol consumption in these areas. For young Mexican-American women in particular, border residence is linked to heightened vulnerability to alcohol dependence. PMID:23278433

    This occasional paper identifies applicable cooperative monitoring techniques and develops models for possible application in the context of the border between China and India. The 1993 and 1996 Sino-Indian agreements on maintaining peace and tranquility along the Line of Actual Control (LAC) and establishing certain confidence building measures (CBMs), including force reductions and limitation on military exercises along their common border, are used to examine the application of technically based cooperative monitoring in both strengthening the existing terms of the agreements and also enhancing trust. The paper also aims to further the understanding of how and under what conditions technology-based tools can assist in implementing existing agreements on arms control and confidence building. The authors explore how cooperative monitoring techniques can facilitate effective implementation of arms control agreements and CBMS between states and contribute to greater security and stability in bilateral, regional, and global contexts.

  1. Cross-Border Policy Effects on Alcohol Outcomes: Drinking Without Thinking on the U.S.-Mexico Border?

    2014-01-01

    Background Rates of alcohol-related outcomes are sensitive to policy differences in politically distinct, adjacent territories. Factors that shape these cross-border effects, particularly when the policy differences are longstanding, remain poorly understood. We compared the ability of two classes of variables with theoretical relevance to the U.S.-Mexico border context – bar attendance and alcohol-related social-cognitive variables – to explain elevated drinking on the U.S. side of the border relative to other areas of the U.S. Methods Data were collected from multi-stage cluster samples of adult Mexican Americans on and off the U.S.-Mexico Border (current drinker N=1351). Structural equation models were used to test drinking context (frequency of bar attendance) and six different social-cognitive variables (including alcohol-related attitudes, norms, motives, and beliefs) as mediators of border effects on a composite drinking index. Results The border effect on drinking varied by age (with younger adults showing a stronger effect), consistent with previous findings and known risk factors in the region. Contrary to theoretical expectations, six different social-cognitive variables – despite relating strongly with drinking – were comparable in border and non-border areas (within and across age) and played no role in elevated drinking on the border. Conversely, elevated drinking among border youth was mediated by bar attendance. This mediated moderation effect held after adjusting for potential sociodemographic and neighborhood-level confounders. Conclusions Increased drinking among U.S.-Mexico border youth is explained by patterns of bar attendance, but not by more permissive alcohol-related social-cognitive variables in border areas: Border youth attend bars and drink more than their non-border counterparts, despite having comparable alcohol-related beliefs, attitudes, norms, and motives for use.

    This systematic review elaborates the concepts and impacts of border malaria, particularly on the emergence and spread of Plasmodium falciparum and Plasmodium vivax multidrug resistance (MDR) malaria on Thailand-Myanmar and Thailand-Cambodia borders. Border malaria encompasses any complex epidemiological settings of forest-related and forest fringe-related malaria, both regularly occurring in certain transmission areas and manifesting a trend of increased incidence in transmission prone areas along these borders, as the result of interconnections of human settlements and movement activities, cross-border population migrations, ecological changes, vector population dynamics, and multidrug resistance. For regional and global perspectives, this review analyzes and synthesizes the rationales pertaining to transmission dynamics and the vulnerabilities of border malaria that constrain surveillance and control of the world's most MDR falciparum and vivax malaria on these chaotic borders.

    Millions of people live on the U.S.-Mexico border, drawn by employment opportunities from industry and agriculture, and booming growth is expected to continue in the coming decades. But the influx of people has long outstripped the capacity of border towns and cities to provide for their citizens, and a large percentage of the population lives in sprawling, underserviced shantytowns. Although investment in environmental infrastructure on both sides has led to improvements, shortages among necessities such as drinking water, wastewater treatment, and solid waste disposal are at crisis levels. In addition, a host of diseases including gastrointestinal infections, asthma, tuberculosis, multiple myeloma, systemic lupus erythematosus, hepatitis A, neural tube defects, and lead poisoning have been linked to environmental conditions on the border. Ongoing binational studies are attempting to define the breadth of the public and environmental health crisis and find ways to help make the border a healthier place. PMID:10903625

    Drawing upon research conducted on cross-border patients living in Laos and seeking care in Thailand, this paper examines the important role played by social networks in patients' decision-making and on the itineraries they choose to seek treatment on the Thai side of the border. Due to the vastly contrasting situations between the two countries in terms of healthcare supply, and considering Laotians' increasing demand for high quality healthcare, a number of them have managed to satisfy their needs by combining cross-border treatment with the use of the healthcare facilities provided by their own country. This study consisted first of household surveys conducted in five border areas (2006-2007) in Laos in order to quantify and map out cross-border healthcare-related travel patterns. Afterwards, interviews were conducted with cross-border patients (55), Laotian and Thai medical doctors (6), Thai social workers (5), and officials working in public institutions (12). While socioeconomic and spatial factors partly explain cross-border mobility, patients' social networks significantly influence treatment itineraries throughout the decision-making process, including logistical and financial considerations. The social networks existing at different geographical levels (neighbourhood, regional and global) are therefore a powerful analytical tool not only for understanding the emergence of these cross-border movements but also for justifying them in an authoritarian political environment such as Lao PDR's.

    In most watershed-modeling studies, flow is calibrated at one monitoring site, usually at the watershed outlet. Like many arid and semi-arid watersheds, the main reach of the Santa Cruz watershed, located on the Arizona-Mexico border, is discontinuous for most of the year except during large flood events, and therefore the flow characteristics at the outlet do not represent the entire watershed. Calibration is required at multiple locations along the Santa Cruz River to improve model reliability. The objective of this study was to best portray surface water flow in this semiarid watershed and evaluate the effect of multi-gage calibration on flow predictions. In this study, the Soil and Water Assessment Tool (SWAT) was calibrated at seven monitoring stations, which improved model performance and increased the reliability of flow, in the Santa Cruz watershed. The most sensitive parameters to affect flow were found to be curve number (CN2), soil evaporation and compensation coefficient (ESCO), threshold water depth in shallow aquifer for return flow to occur (GWQMN), base flow alpha factor (Alpha_Bf), and effective hydraulic conductivity of the soil layer (Ch_K2). In comparison, when the model was established with a single calibration at the watershed outlet, flow predictions at other monitoring gages were inaccurate. This study emphasizes the importance of multi-gage calibration to develop a reliable watershed model in arid and semiarid environments. The developed model, with further calibration of water quality parameters will be an integral part of the Santa Cruz Watershed Ecosystem Portfolio Model (SCWEPM), an online decision support tool, to assess the impacts of climate change and urban growth in the Santa Cruz watershed.

    Wireless sensor networks have been proposed as promising candidates to provide automated monitoring, target tracking, and intrusion detection for border surveillance. In this paper, we demonstrate an ad-hoc wireless sensor network system for border surveillance. The network consists of heterogeneously autonomous sensor nodes that distributively cooperate with each other to enable a smart border in remote areas. This paper also presents energy-aware and sleeping algorithms designed to maximize the operating lifetime of the deployed sensor network. Lessons learned in building the network and important findings from field experiments are shared in the paper.

  17. Metrics for border management systems.

    SciTech Connect

    2009-07-01

    There are as many unique and disparate manifestations of border systems as there are borders to protect. Border Security is a highly complex system analysis problem with global, regional, national, sector, and border element dimensions for land, water, and air domains. The complexity increases with the multiple, and sometimes conflicting, missions for regulating the flow of people and goods across borders, while securing them for national security. These systems include frontier border surveillance, immigration management and customs functions that must operate in a variety of weather, terrain, operational conditions, cultural constraints, and geopolitical contexts. As part of a Laboratory Directed Research and Development Project 08-684 (Year 1), the team developed a reference framework to decompose this complex system into international/regional, national, and border elements levels covering customs, immigration, and border policing functions. This generalized architecture is relevant to both domestic and international borders. As part of year two of this project (09-1204), the team determined relevant relative measures to better understand border management performance. This paper describes those relative metrics and how they can be used to improve border management systems.

    2016-01-01

    In two recent judgements, the European Court of Human Rights (ECtHR) has given an alarming signal regarding the placement, care and treatment of mentally disordered offenders in Belgium. This article analyses these judgements and the Court's assessment that Belgium faces a structural problem regarding the detention of people with a mental illness in prison. By exploring other recent ECtHR decisions across the EU and combining this with an analysis of international norms and standards, it contends that there is something amiss regarding the post-trial approach towards mentally disordered offenders in an EU-wide context. The potential hazards of this situation, from both an individual and an EU perspective are then presented by analysing the EU Framework Decision on the transfer of prisoners (which aims to facilitate offender rehabilitation) and the EU Court of Justice's interpretation of the relationship between instruments like the Framework Decision that are based on mutual recognition and fundamental rights. Lastly, the EU's initiative for enhancing procedural rights in criminal proceedings through the Roadmap trajectory, and the subsequent Commission Recommendation of 27 November 2013, are scrutinized. Based on this research, the article pinpoints the flaws and vacuums that currently exist for mentally disordered offenders, and the negative outcome this may have on the legitimacy and effectiveness of the European Area of Freedom, Security and Justice.

    The Indo-Gangetic Plains (IGP) in northern South Asia are among the most polluted and most densely populated places in the world, and they are upwind of vulnerable ecosystems in the Himalaya mountains. They are also fragmented across 5 countries between which movement of people, data, instruments and scientific understanding have been very limited. ICIMOD's Atmosphere Initiative has for the past three years been working on filling data gaps in the region, while facilitating collaborations across borders. It has established several atmospheric observatories at low and mid elevations in Bhutan and Nepal that provide new data on the inflow of pollutants from the IGP towards the mountains, as well as quantify the effects of local emissions on air quality in mountain cities. EGU will be the first international conference where these data will be presented. ICIMOD is in the process of setting up data servers through which data from the region will be shared with scientists and the general public across borders. Meanwhile, to promote cross-border collaboration among scientists in the region, while addressing an atmospheric phenomenon that affects the lives of the several hundred million people, ICIMOD' Atmosphere Initiative has been coordinating an interdisciplinary multi-year study of persistent winter fog over the Indo-Gangetic Plains, with participation by researchers from Pakistan, India, China, Nepal, Bhutan and Bangladesh. Using a combination of in-situ measurements and sample collection, remote sensing, modeling and community based research, the researchers are studying how changing moisture availability and air pollution have led to increases in fog frequency and duration, as well as the fog's impacts on local communities and energy demand that may affect air pollution emissions. Preliminary results of the Winter 2015-2016 field campaign will be shown.

    Methods are described to isolate intact brush borders and brush border membranes from renal cell homogenates. A rapid method yields sealed vesicles that reconstitute renal brush border transport. In one variation of this protocol, 10 to 20 mM CaCl2 or MgCl2 is added to aggregate non-brush border structures for subsequent removal by centrifugation. For analytical studies, guidance is provided for subsequent purification steps including preparative free-flow and aqueous two-phase partition. Marker enzymes and morphological parameters are included for assessment of yield and fraction purity. PMID:18228514

    This paper discusses defectivity of a black border around the mask pattern of a reticle for extreme EUV lithography. An opaque image border is intended to overcome the limitation of the reticle masking blades of the scanner, in providing sufficiently sharp and accurate image delineation on wafer. The most commonly applied "black border" method for EUV reticles has the multilayer mirror removed in the image border area. A dedicated mask with such etched ML image border has been generated. It includes several modules of patterns, each surrounded by black border, so that each can be imaged separately with minimized background dose caused by its border. The printability of programmed defects within this image border has been assessed on an NXE3100 EUV scanner. Studied defect types include ML pedestals with and without absorber still on top. Especially the former must be totally avoided as such clear defect is very printable and can even erase parts of the pattern in neighboring dies.

    Exchanging ideas with like-minded, enthusiastic people interested in the same topic is crucial for the advancement of a scientist's career. Several Regional Student Groups (RSGs) of the International Society for Computational Biology (ISCB) Student Council have cooperated in the last six years to organize scientific workshops and conferences. With motivated students, it is possible to create a memorable event for fellow scientists; in doing so, the organizers gain valuable experiences. While collaborating across borders and time zones can be difficult, feedback from event organizers was always positive. When limited resources are juxtaposed with great ideas and a network of contacts, the outcome is always an amazing experience, despite organizers being separated geographically across different countries.

    2005-05-01

    A top concern in homeland security efforts is the lack of ability to monitor the thousands of miles of open border with our neighbors. It is not currently feasible to continually monitor the borders for illegal intrusions. The MicroSensor System (MSS) seeks to achieve a low-cost monitoring solution that can be efficiently deployed for border patrol applications. The modifications and issues regarding the unique requirements of this application will be discussed and presented. The MicroSensor System was developed by the Defense Microelectronics Activity (DMEA) for military applications, but border patrol applications, with their unique sensor requirements, demand careful adaptation and modification from the military application. Adaptation of the existing sensor design for border applications has been initiated. Coverage issues, communications needs, and other requirements need to be explored for the border patrol application. Currently, border patrol has a number of deficiencies that can be addressed with a microsensor network. First, a distributed networked sensor field could mitigate the porous border intruder detection problem. Second, a unified database needs to be available to identify aliens attempting to cross into the United States. This database needs to take unique characteristics (e.g. biometrics, fingerprints) recovered from a specialized field unit to reliably identify intruders. Finally, this sensor network needs to provide a communication ability to allow border patrol officers to have quick access to intrusion information as well as equipment tracking and voice communication. MSS already addresses the sensing portion of the solution, including detection of acoustic, infrared, magnetic, and seismic events. MSS also includes a low-power networking protocol to lengthen the battery life. In addition to current military requirements, MSS needs a solar panel solution to extend its battery life to 5 years, and an additional backbone communication link

  10. Cross-border ties and Arab American mental health.

    PubMed

    Samari, Goleen

    2016-04-01

    Due to increasing discrimination and marginalization, Arab Americans are at a greater risk for mental health disorders. Social networks that include ties to the country of origin could help promote mental well-being in the face of discrimination. The role of countries of origin in immigrant mental health receives little attention compared to adjustment in destination contexts. This study addresses this gap by analyzing the relationship between nativity, cross-border ties, and psychological distress and happiness for Arab Americans living in the greater Detroit Metropolitan Area (N = 896). I expect that first generation Arab Americans will have more psychological distress compared to one and half, second, and third generations, and Arab Americans with more cross-border ties will have less psychological distress and more happiness. Data come from the 2003 Detroit Arab American Study, which includes measures of nativity, cross-border ties--attitudes, social ties, media consumption, and community organizations, and the Kessler-10 scale of psychological distress and self-reported happiness. Ordered logistic regression analyses suggest that psychological distress and happiness do not vary much by nativity alone. However, cross-border ties have both adverse and protective effects on psychological distress and happiness. For all generations of Arab Americans, cross-border attitudes and social ties are associated with greater odds of psychological distress and for first generation Arab Americans, media consumption is associated with greater odds of unhappiness. In contrast, for all generations, involvement in cross-border community organizations is associated with less psychological distress and for the third generation, positive cross-border attitudes are associated with higher odds of happiness. These findings show the complex relationship between cross-border ties and psychological distress and happiness for different generations of Arab Americans. PMID:26999416

    The article deals with the evolution of the concept of borders between human groups and with its slow evolution from the initial no men's land zones to the ideal single-dimension linear borders. In ancient times the first borders were natural, such as mountain ranges or large rivers until, with the development of Geodesy, astronomical borders based on meridians and parallels became a favourite natural base. Actually, Modern States adopted these to fix limits in unknown conquered territories. The postmodern thought led give more importance to cultural borders until, in the most recent times, is becoming rather impossible to fix borders in the virtual cyberspace.

    Since 2002 a regional seismic network from Jalisco Civil Defense and University of Guadalalajara is monitoring seismicity at the northwest border of Jalisco block. With the installation of a seismic station on Ceboruco Volcano, by Nayarit Civil Defense, coverage of the network extends to east. Ceboruco Volcano is located on the Tepic-Zacoalco graben, the east border of Jalisco block, this allow us to begin to monitoring this area. The zone of Bahia de Banderas, between the north coast of Jalisco and south coast of Nayarit, probably on a tectonic triple point, is a region of high seismic potential. Activ tectonic structures and clusters in the zone of El Tuito and the Dam Cajon de Pe¤as have been identified. The seismicity in the north area of the bay is low, meanwhile in the south, where the bay is deeper, the seismicity level is higher with an East-West tendency. At the east, the Amatlan de Ca¤as-Ameca zone presents continue activity, here have been possible to locate events with local magnitude between 2 and 4. Tectonovolcanic events registred at Ceboruco station presents waveform with scattering. The seismic distribution of the coast of Jalisco shows parallel alignments to the trench throughout al the coast. Other perpendicular alignments to the coastline show active morphologic structures within the Jalisco block related to the subduction of the Rivera plate under the Jalisco block.

    Limited detection resolution leads to fuzzy areas during the measurement, and the discrimination of the border of a fuzzy area helps to use the resolution stability. In this way, measurement precision is greatly improved, hence this phenomenon is named the border effect. The resolution fuzzy area and its application should be studied to realize high-resolution measurement. During the measurement of any frequency signal, the fuzzy areas of phase-coincidence detection are always discrete and irregular. In this paper the difficulty in capturing the border information of discrete fuzzy areas is overcome and extra-high resolution measurement is implemented. Measurement precision of any frequency-signal can easily reach better than 1 × 10-11/s in a wide range of frequencies, showing the great importance of the border effect. An in-depth study of this issue has great significance for frequency standard comparison, signal processing, telecommunication, and fundamental subjects.

    2015-01-01

    The purpose of this review is to synthesize the current knowledge on the international movement of patients and biopsied embryo cells for pre-implantation genetic diagnosis and its different applications. Thus far, few attempts have been made to identify the specific nature of this phenomenon called 'cross-border reprogenetic services'. There is scattered evidence, both empirical and speculative, suggesting that these services raise major issues in terms of service provision, risks for patients and the children-to-come, the legal liabilities of physicians, as well as social justice. To compile this evidence, this review uses the narrative overview protocol combined with thematic analysis. Five major themes have emerged from the literature at the conjunction of cross-border treatments and reprogenetics: 'scope', 'scale', 'motivations', 'concerns', and 'governance'. Similar themes have already been observed in the case of other medical tourism activities, but this review highlights their singularity with reprogenetic services. It emphasizes the diagnostic and autologous feature of reprogenetics, the constant risk of misdiagnosis, the restriction on certain tests for medically controversial conditions, and the uncertain accessibility of genetic counseling in cross-border settings.

    Leptospirosis is an epidemic-prone zoonotic disease that occurs worldwide. In Central America, leptospirosis outbreaks have been reported in almost all countries; Nicaragua in particular has faced several outbreaks. The objective of this study was to stratify the risk and identify “critical areas” for leptospirosis outbreaks in Nicaragua, and to perform an exploratory analysis of potential “drivers”. This ecological study includes the entire country (153 municipalities). Cases from 2004 to 2010 were obtained from the country’s health information system, demographic and socioeconomic variables from its Census, and environmental data from external sources. Criteria for risk stratification of leptospirosis were defined. Nicaragua reported 1,980 cases of leptospirosis during this period, with the highest percentage of cases (26.36%) in León, followed by Chinandega (15.35%). Among the 153 municipalities, 48 were considered critical areas, 85 were endemic and 20 silent. Using spatial and statistical analysis, the variable presenting the most evident pattern of association with critical areas defined by top quintile of incidence rate is the percentage of municipal surface occupied by the soil combination of cambisol (over pyroclastic and lava bedrock) and andosol (over a volcanic ashes foundation). Precipitation and percentage of rural population are also associated with critical areas. This methodology and findings could be used for Nicaragua’s Leptospirosis Intersectoral Plan, and to identify possible risk areas in other countries with similar drivers. PMID:23202822

  18. Tectonic analysis of a Viking graben border fault

    SciTech Connect

    Fayerland, M.S.

    1983-11-01

    The Viking graben has been proven to be an aulacogen on a passive continental margin. The rifting started in the Late Permian and had numerous episodes throughout the Mesozoic. The strongest tectonic events occurred in the late Cimmerian phases. Toward the end of the Cretaceous, the taphrogeny ceased and the graben became part of a rigid continental margin. A Laramian phase, however, did occur. The Tertiary basins had their depocenters close to the Viking and the Central graben axes, but the outline of these smooth and rounded basins were independent of the graben border faults. However, in one area, in the central part of the North Sea, a Viking graben border fault was reactivated in the Paleocene-Eocene. This rejuvenation has resulted in such structural features as ''flower'' structures and normal faults along the old Cimmerian Viking graben border fault. the tensional features are found along one border fault dogleg trend, and the compressive features are found along another. This is explained as a response to strike-slip reactivation of the old fault. The transient movements coincide with the incipient seafloor spreading in the Norwegian-Greenland Sea area and may be related to consequent rotation of the Shetland platform relative to the Fennoscandian shield.

    This paper presents an overview of pollution issues affecting the Mexico-US border region, and briefly traces the development of the international legal framework which covers Mexico-US border relations on environmental issues. Examples from different border areas are used to illustrate surface water, groundwater, air pollution, and hazardous waste problems associated with the rapid growth and industrialization of areas along the border. Some of the specific issues presented include the Tijuana-San Diego sewage problem, the New River toxic discharges, Nogales Wash groundwater pollution, air pollution in Cd. Juarez-El Paso, and the Alco-Pacifico lead contamination case in Tijuana, B.C. Additional research to characterize the extent of border area pollution and resultant ecological impacts is fundamental in the development of binational policies to deal with these problems. Another priority need is the application of risk assessment models, which will help policy makers on both sides of the border to coordinate efforts and allocate resources to solve this crisis. Immediate attention should be directed toward acquiring information necessary to evaluate the impacts of border-area pollution on natural ecosystems.

    2005-09-01

    Neuronal ceroid lipofuscinosis (NCL) is a neurodegenerative disease found in Border collie dogs, humans, and other animals. Disease gene studies in humans and animals provided candidates for the NCL gene in Border collies. A combination of linkage analysis and comparative genomics localized the gene to CFA22 in an area syntenic to HSA13q that contains the CLN5 gene responsible for the Finnish variant of human late infantile NCL. Sequencing of CLN5 revealed a nonsense mutation (Q206X) within exon 4 that correlated with NCL in Border collies. This truncation mutation should result in a protein product of a size similar to that of some mutations identified in human CLN5 and therefore the Border collie may make a good model for human NCL. A simple test was developed to enable screening of the Border collie population for carriers so the disease can be eliminated as a problem in the breed. PMID:16033706

    2014-01-01

    Purpose: The purpose of this paper is to describe the food landscape of Texas using the CDC’s Modified Retail Food Environment (mRFEI) and to make comparisons by border/non-border. Methods: The Modified Retail Food Environment index (mRFEI (2008)) is an index developed by the CDC that measures what percent of the total food vendors in a census track sell healthy food. The range of values is 0 (unhealthy areas with limited access to fruits and vegetables) to (100—Healthy). These data were linked to 2010 US Census socioeconomic and ethnic concentration data. Spatial analysis and GIS techniques were applied to assess the differences between border and non-border regions. Variables of interest were mRFEI score, median income, total population, percent total population less than five years, median age, % receiving food stamps, % Hispanic, and % with a bachelor degree. Results: Findings from this study reveal that food environment in Texas tends to be characteristic of a “food desert”. Analysis also demonstrates differences by border/non-border location and percent of the population that is foreign born and by percent of families who receive food stamps. Conclusions: Identifying the relationship between socioeconomic disparity, ethnic concentration and mRFEI score could be a fundamental step in improving health in disadvantage communities, particularly those on the Texas-Mexico border.

    Introduction The US–Mexico border region has 15 million residents and 300,000 births annually. Reproductive health concerns have been identified on both sides of the border, but comparable information about reproductive health is not available. The objective of this study was to compare reproductive health indicators among populations in this region. Methods We used 2009 US Hispanic and Mexican birth certificate data to compare births inside the border region, elsewhere within the border states, and in the United States and Mexico overall. We examined trends in total fertility and birth rates using birth data from 2000 through 2009 and intercensal population estimates. Results Among women in the border region, US women had more lifetime births than Mexican women in 2009 (2.69 births vs 2.15 births) and throughout the decade. Birth rates in the group aged 15 to 19 years were high in both the US (73.8/1,000) and Mexican (86.7/1,000) border regions. Late or no prenatal care was nearly twice as prevalent in the border regions as in the nonborder regions of border states. Low birth weight and preterm and early-term birth were more prevalent in the US border than in the Mexican border region; US border rates were higher and Mexican rates were lower than their corresponding nonborder and national rates. We found some variations within border states. Conclusion These findings constitute the first population-based information on the reproductive health of the entire Hispanic US–Mexico border population. Evidence of disparities warrants exploration at state and local levels. Teen pregnancy and inadequate prenatal care are shared problems in US–Mexico border communities and suggest an area for binational cooperation. PMID:23948338

    Introduction: Cross-border firing are increasingly being common in the modern era. The injuries resulting from these low intensity conflicts are a source of anxiety among treating physicians and their respective governments. The provisions are required to minimise the suffering of the victims viz. Mode of injuries, mortality patterns, adequacy of treatment at pre-hospital and tertiary care hospital and provisions to decrease morbidity and mortality for the people living in these areas. Materials and Methods: A retrospective study was conducted in GMCH, Jammu who suffered injuries due to cross border firing in the month of October, 2014. 68 patients were reported in the causality wing. All the patients were referred from level 2 trauma centre. There were 51 males and 17 females out of which 5 were children. The cause of injury, involvement of organ system, cause of mortality and morbidity and loopholes in prehospital management were identified. Results: Sharpnel were the most common cause of injury followed by indirect trauma. The common cause of mortality was abdominal and thoracic injuries. There were 4 deaths at hospital 2 of which were brought dead and 2 died during the course of treatment. There were twenty patients with extremity injuries, fourteen with chest trauma, eleven with abdomen including parineal injuries, three with head injuries, eight with ENT injuries, three with eye injuries and nine with splinters in the back out of which two were in the spinal canal. Conclusion: Prehospital stabilisation, early transport, in-transit resuscitation, immediate surgery if required and implementation of triage model and ATLS protocol has been the key to reduce mortality and morbidity.

    2015-12-01

    This study quantifies the inconsistency in gauge precipitation observations across the border of Alaska and Yukon. It analyses the precipitation measurements by the national standard gauges (National Weather Service (NWS) 8 in. gauge and Nipher gauge) and the bias-corrected data to account for wind effect on the gauge catch, wetting loss and trace events. The bias corrections show a significant amount of errors in the gauge records due to the windy and cold environment in the northern areas of Alaska and Yukon. Monthly corrections increase solid precipitation by 136 % in January and 20 % for July at the Barter Island in Alaska, and about 31 % for January and 4 % for July at the Yukon stations. Regression analyses of the monthly precipitation data show a stronger correlation for the warm months (mainly rainfall) than for cold month (mainly snowfall) between the station pairs, and small changes in the precipitation relationship due to the bias corrections. Double mass curves also indicate changes in the cumulative precipitation over the study periods. This change leads to a smaller and inverted precipitation gradient across the border, representing a significant modification in the precipitation pattern over the northern region. Overall, this study discovers significant inconsistency in the precipitation measurements across the USA-Canada border. This discontinuity is greater for snowfall than for rainfall, as gauge snowfall observations have large errors in windy and cold conditions. This result will certainly impact regional, particularly cross-border, climate and hydrology investigations.

    2003-09-01

    During the last 12 years the European Union (EU) has financed the new member applicant countries of Central and Eastern Europe in their preparation for joining the EU. Based on this enlargement of the EU, funding for border protection has been made available from the overall infrastructure improvement budget. Border protection was required in areas where border conflicts had taken place and to limit illegal immigration and smuggling. After 9/11 defence against terrorist activities will no doubt be added to the requirement. This paper describes the approach taken in the provision of police and para-military Mobile Surveillance Units (MSU's). This approach may also be considered for the US Homeland Defense initiative. These MSU's utilize standard road vehicles converted to use high performance military thermal imagers, such as SiGMA. In future the current, in service, MSU will require increased sensor integration and networking to cover land and coastal borders. The underlying key is affordability for the police and para-military markets while retaining the highest performance derived from the latest military standard thermal imagers.

  12. Environmental exposure of road borders to zinc.

    PubMed

    Blok, J

    2005-09-15

    The emissions of zinc along roads originating from tyre wear, corrosion of safety fence and other traffic-related sources have been quantified and validated by measured long-term loads in road run-off and airborne solids (drift) for 29 published case studies. The distribution pattern over the road border at various distances from the edge of the paved surface is assessed on the basis of 38 published case studies with measured concentrations in soil. For the impact assessment, the road border is differentiated into a zone that is part of the "technosphere" and the "target zone" beyond that technosphere that can be considered as part of the receiving environment. The "technosphere" of the road includes the central reservation, the hard and the soft shoulder or, if one or both shoulders are not present, the so-called obstacle "free zone" that is defined by road engineers. Pollution within the technosphere may require appropriate management of solid disposal and isolation from groundwater to prevent further distribution of pollutants to the environment. In the target zone along regional roads, the zinc load is about 4 mg/m(2) year and this is of the same order of magnitude as that of atmospheric deposition in areas beyond the influence of roads (background). In the target zone along highways, the zinc load is increased in comparison to the background deposition. The average load of about 38 mg/m(2) year is similar to that in fertilised agricultural land. Because most of the emitted zinc stays in the technosphere, the total amount entering this target zone along highways is limited. From the 140 tons of zinc per year that is released from tyre wear in The Netherlands, 64 tons is emitted in the urban area, 6.5 tons reaches to the target zones of all roads and only 1.1 tons of zinc will enter the target zone along highways. This amount will be further decreased by the application of porous asphalt in the near future. The emission from safety fence corrosion does not enter

    In recent years trans-boundary incursions from Petén, Guatemala into Belize's Maya Mountain Massif (MMM) have increased. The incursions are rapidly degrading cultural and natural resources in Belize's protected areas. Given the local, regional and global importance of the MMM and the scarcity of deforestation data, our research team conducted a time series analysis 81 km by 12 km along the Belize-Guatemalan border adjacent to the protected areas of the MMM. Analysis drew on Landsat imagery from 1991 to 2014 to determine historic deforestation rates. The results indicate that the highest deforestation rates in the study area were -1.04% and -6.78% loss of forested area per year in 2012-2014 and 1995-1999 respectively. From 1991 to 2014, forested area decreased from 96.9 % to 85.72 % in Belize and 83.15 % to 31.52 % in Guatemala. During the study period, it was clear that deforestation rates fluctuated in Belize's MMM from one time-period to the next. This seems linked to either a decline in deforestation rates in Guatemala, the vertical expansion of deforestation in Guatemalan forested areas and monitoring. The results of this study urge action to reduce incursions and secure protected areas and remaining forest along the Belize-Guatemalan border.

  14. Semantic Borders and Incomplete Understanding.

    2016-03-01

    In this article, we explore a fundamental issue of Cultural Psychology, that is our "capacity to make meaning", by investigating a thesis from contemporary philosophical semantics, namely, that there is a decisive relationship between language and rationality. Many philosophers think that for a person to be described as a rational agent he must understand the semantic content and meaning of the words he uses to express his intentional mental states, e.g., his beliefs and thoughts. Our argument seeks to investigate the thesis developed by Tyler Burge, according to which our mastery or understanding of the semantic content of the terms which form our beliefs and thoughts is an "incomplete understanding". To do this, we discuss, on the one hand, the general lines of anti-individualism or semantic externalism and, on the other, criticisms of the Burgean notion of incomplete understanding - one radical and the other moderate. We defend our understanding that the content of our beliefs must be described in the light of the limits and natural contingencies of our cognitive capacities and the normative nature of our rationality. At heart, anti-individualism leads us to think about the fact that we are social creatures, living in contingent situations, with important, but limited, cognitive capacities, and that we receive the main, and most important, portion of our knowledge simply from what others tell us. Finally, we conclude that this discussion may contribute to the current debate about the notion of borders. PMID:26111737

    The Ocean Drilling Program (ODP) has completed three expeditions bordering South America and is in the planning stages of a further expedition. The first cruise, Leg 110, drilled at six sites on a transect across the structural boundary between the overthrusting Barbados Ridge Complex and Atlantic abyssal plain (Caribbean/Atlantic Plate Boundary) in order to investigate structural, hydrological, and diagenetic effects of the transition from undeformed deep sea sediments to stratally disrupted melange on land. The second cruise, Leg 112, drilled ten sites to investigate the geological and paleoceanographic history of the area between the Peru Trench (which marks the suture between the Nazca and South American Plates) and the Peruvian coast. A third cruise, Leg 1 41, drilled the Chile Triple Junction, which represents the only presently active ridge-crest subduction and the physical properties and geochemistry of gas hydrates in oceanic sediments. A fourth cruise off South America is presently in the planning stage by the international science community. This proposed paleoceanographic transect is on the Ceara Rise off northern Brazil and has a proposed objective, amongst others, of studying the history of deep water flow of the Atlantic during the Cenozoic with an emphasis on the relationships between deep water circulation chemistry and the Earth's climate. This paper focuses on the significant scientific results of the above cruises and discusses future plans off South America.

    In 1997, the Centers for Disease Control and Prevention, the Mexican Secretariat of Health, and border health officials began the development of the Border Infectious Disease Surveillance (BIDS) project, a surveillance system for infectious diseases along the U.S.-Mexico border. During a 3-year period, a binational team implemented an active, sentinel surveillance system for hepatitis and febrile exanthems at 13 clinical sites. The network developed surveillance protocols, trained nine surveillance coordinators, established serologic testing at four Mexican border laboratories, and created agreements for data sharing and notification of selected diseases and outbreaks. BIDS facilitated investigations of dengue fever in Texas-Tamaulipas and measles in California–Baja California. BIDS demonstrates that a binational effort with local, state, and federal participation can create a regional surveillance system that crosses an international border. Reducing administrative, infrastructure, and political barriers to cross-border public health collaboration will enhance the effectiveness of disease prevention projects such as BIDS. PMID:12533288

    A major concern of researchers using state data sets for population-based analyses and market share studies in the health care sector is the potential bias caused by 'border crossing'--patients receiving care out of state. By using the Health Care Financing Administration (HCFA) discharge abstract files for 1987 and 1988, we found that 'border crossing' is not a serious problem for the two large states we examined. Only 4.4% of New York patients and 2.15% of California patients received care out of state. At the county and zip code level, 'border crossing' is more frequent but tends to be concentrated in areas adjacent to other states. Even excluding all zips with more than 10% of patients crossing the 'border' results in a small loss of patients (2.2% for New York and 1.0% for California). PMID:8511633

    Modeling real-world scenarios is a challenge for traditional social science researchers, as it is often hard to capture the intricacies and dynamisms of real-world situations without making simplistic assumptions. This imposes severe limitations on the capabilities of such models and frameworks. Complex population dynamics during natural disasters such as pandemics is an area where computational social science can provide useful insights and explanations. In this paper, we employ a novel intent-driven modeling paradigm for such real-world scenarios by causally mapping beliefs, goals, and actions of individuals and groups to overall behavior using a probabilistic representation called Bayesian Knowledge Bases (BKBs). To validate our framework we examine emergent behavior occurring near a national border during pandemics, specifically the 2009 H1N1 pandemic in Mexico. The novelty of the work in this paper lies in representing the dynamism at multiple scales by including both coarse-grained (events at the national level) and finegrained (events at two separate border locations) information. This is especially useful for analysts in disaster management and first responder organizations who need to be able to understand both macro-level behavior and changes in the immediate vicinity, to help with planning, prevention, and mitigation. We demonstrate the capabilities of our framework in uncovering previously hidden connections and explanations by comparing independent models of the border locations with their fused model to identify emergent behaviors not found in either independent location models nor in a simple linear combination of those models.

    We investigate the impact of borders on the topology of spatially embedded networks. Indeed territorial subdivisions and geographical borders significantly hamper the geographical span of networks thus playing a key role in the formation of network communities. This is especially important in scientific and technological policy-making, highlighting the interplay between pressure for the internationalization to lead towards a global innovation system and the administrative borders imposed by the national and regional institutions. In this study we introduce an outreach index to quantify the impact of borders on the community structure and apply it to the case of the European and US patent co-inventors networks. We find that (a) the US connectivity decays as a power of distance, whereas we observe a faster exponential decay for Europe; (b) European network communities essentially correspond to nations and contiguous regions while US communities span multiple states across the whole country without any characteristic geographic scale. We confirm our findings by means of a set of simulations aimed at exploring the relationship between different patterns of cross-border community structures and the outreach index.

    EUV lithography is the most promising technology for semiconductor device manufacturing of the 10nm node and beyond. The EUV mask is a key element in the lithographic scanner optical path. The image border is a pattern free dark area around the die on the photomask serving as transition area between the parts of the mask that is shielded from the exposure light by the Reticle Masking (REMA) blades and the die. When printing a die at dense spacing on an EUV scanner, the EUV light reflection from the image border overlaps edges of neighboring dies, affecting CD and contrast in this area. To reduce this effect an etched multilayer type black border was developed, and it was demonstrated that CD impact at the edge of a die is strongly reduced with this type of the black border (BB). However, wafer printing result still showed some CD change influenced by the black border reflection. It was proven that the CD shift was caused by DUV Out of Band (OOB) light which is emitted from EUV light source. New types of a multilayer etched BB were evaluated and showed a good potential for DUV light suppression. In this study, a novel black border called Hybrid Black Border has been developed which allows to eliminate EUV and DUV OOB light reflection. Direct measurements of OOB light from HBB and Normal BB are performed on NXE:3300B ASML EUV scanner; it is shown that HBB OOB reflection is 3x lower than that of Normal BB. Finally, we state that HBB is a promising technology allowing for CD control at die edges.

    Background Women's malnutrition, particularly undernutrition, remains an important public health challenge in Ethiopia. Although various studies examined the levels and determinants of women's nutritional status, the influence of living close to an international border on women's nutrition has not been investigated. Yet, Ethiopian borders are regularly affected by conflict and refugee flows, which might ultimately impact health. Objective To investigate the impact of living close to borders in the nutritional status of women in Ethiopia, while considering other important covariates. Design Our analysis was based on the body mass index (BMI) of 6,334 adult women aged 20–49 years, obtained from the 2011 Ethiopian Demographic and Health Survey (EDHS). A Bayesian multilevel multinomial logistic regression analysis was used to capture the clustered structure of the data and the possible correlation that may exist within and between clusters. Results After controlling for potential confounders, women living close to borders (i.e. ≤100 km) in Ethiopia were 59% more likely to be underweight (posterior odds ratio [OR]=1.59; 95% credible interval [CrI]: 1.32–1.90) than their counterparts living far from the borders. This result was robust to different choices of border delineation (i.e. ≤50, ≤75, ≤125, and ≤150 km). Women from poor families, those who have no access to improved toilets, reside in lowland areas, and are Muslim, were independently associated with underweight. In contrast, more wealth, higher education, older age, access to improved toilets, being married, and living in urban or lowlands were independently associated with overweight. Conclusions The problem of undernutrition among women in Ethiopia is most worrisome in the border areas. Targeted interventions to improve nutritional status in these areas, such as improved access to sanitation, economic and livelihood support, are recommended. PMID:27388539

  7. Use of border information in the classification of mammographic masses

    We are developing a new method to characterize the margin of a mammographic mass lesion to improve the classification of benign and malignant masses. Towards this goal, we designed features that measure the degree of sharpness and microlobulation of mass margins. We calculated these features in a border region of the mass defined as a thin band along the mass contour. The importance of these features in the classification of benign and malignant masses was studied in relation to existing features used for mammographic mass detection. Features were divided into three groups, each representing a different mass segment: the interior region of a mass, the border and the outer area. The interior and the outer area of a mass were characterized using contrast and spiculation measures. Classification was done in two steps. First, features representing each of the three mass segments were merged into a neural network classifier resulting in a single regional classification score for each segment. Secondly, a classifier combined the three single scores into a final output to discriminate between benign and malignant lesions. We compared the classification performance of each regional classifier and the combined classifier on a data set of 1076 biopsy proved masses (590 malignant and 486 benign) from 481 women included in the Digital Database for Screening Mammography. Receiver operating characteristic (ROC) analysis was used to evaluate the accuracy of the classifiers. The area under the ROC curve (Az) was 0.69 for the interior mass segment, 0.76 for the border segment and 0.75 for the outer mass segment. The performance of the combined classifier was 0.81 for image-based and 0.83 for case-based evaluation. These results show that the combination of information from different mass segments is an effective approach for computer-aided characterization of mammographic masses. An advantage of this approach is that it allows the assessment of the contribution of regions rather

    California shares a 150-mile international border with Mexico. Traditionally, this border has seen non-stop illegal migration. In the 1990s, the Border Patrol began a concerted effort to establish and maintain control of the border, beginning in urban San Diego. This heightened law enforcement presence, known as Operation Gatekeeper, changed the westernmost segment of the border from the most permeable to the least permeable. This enforcement pushed migrants into more dangerous crossing areas in eastern San Diego and Imperial Counties, making their trip longer and more physically challenging as they made their way through treacherous mountains, deserts, and irrigation canals. Death rates soared. Political decisions impacted human lives and the caseloads of forensic anthropologists in jurisdictions along the border. Bodies decompose rapidly here, and there are minimal sources of antemortem data. Many of these migrants are never identified. This paper, and this symposium, is an attempt to bring this situation to the notice of other anthropologists and to discuss cooperative means of addressing the issue of identification. PMID:18279233

The system was built to serve maquila industries at the US/Mexican border. The BTFS uses foundation technology developed here at Sandia Laboratories' Advanced Information Systems Lab (AISL), including a distributed object substrate, a general-purpose agent development framework, dynamically generated agent-human interaction via the World-Wide Web, and a collaborative agent architecture. This technology is also the substrate for the Multi-Agent Simulation Management System (MASMAS) proposed for demonstration at this conference. The BTFS executes authenticated transactions among agents performing open trading over the Internet. With the BTFS in place, one could conduct secure international transactions from any site with an Internet connection and a web browser. The BTFS is currently being evaluated for commercialization.

    We investigate the geometrical properties of Plateau borders in an arrangement of connected smectic A free standing films. The geometry is chosen such that a circular Plateau border surrounds a planar smectic film and connects it with two smectic catenoids. It is demonstrated that, similar to soap films, the smectic film geometry can be described by a negative line tension of the circular contact region. Thus, the equilibrium angle between the films depends upon the liquid content in this region, and with increasing liquid content, deviations from Plateau's rule are observed. The experimental results are qualitatively comparable to soap films. A possible origin of slight quantitative differences is discussed.

In the developed countries, notably the U.S., Australia, New Zealand and Europe, medical schools prepare advanced practitioners who can then fill the gap left by the lack of nephrologists. However in areas where physicians are in short supply, nurses often have only basic training and trained APs are not available. In the meantime, kidney disease is taking its toll on the best and the brightest. PMID:26677594

    Rivers, although inherently dynamic, have been chosen as political boundaries since the beginning of colonization for several reasons. Such divisions were chosen namely for their defensive capabilities and military benefits, and because they were often the first features mapped out by explorers. Furthermore, rivers were indisputable boundaries that did not require boundary pillars or people to guard them. However, it is important to understand the complexities of a river as a boundary. All rivers inevitably change over time through processes such as accretion, deposition, cut-off, or avulsion, rendering a political boundary subject to dispute. Depending upon the flow, size, and surrounding land, a river will migrate differently than others. As these natural features migrate one country loses land while another gains land leading to tension between legal rigidity and fluid dynamism. This in turn can manifest in social disruption due to cultural differences, political upheaval, or conflict risk as a result of scarce water resources. The purpose of this research is to assess the temporal and spatial variability of the political boundaries of Peru that follow rivers. Peru shares borders with Colombia, Brazil, Bolivia, Chile, and Ecuador. A large part of its northern border with Colombia follows the Putumayo River and later the Amazon River. Part of its eastern border with Brazil follows the Yavari River and later the Yaquirana River. These rivers are natural features used as political boundaries yet they differ in how each migrates. By means of a spatial and temporal analysis of satellite images it was possible to obtain erosion and deposition areas for the Putumayo River, the portion of the Amazon River that is part of the Peruvian boundary, the Yavari River, and the Yaquirana River. The erosion and deposition areas were related to land distribution among Peru, Colombia, and Brazil. By examining the Digital Elevation Model one can see how the altitude of the

  6. Border bias: the belief that state borders can protect against disasters.

    In this research, we documented a bias in which people underestimate the potential risk of a disaster to a target location when the disaster spreads from a different state, but not when it spreads from an equally distant location within the same state. We term this the border bias. Following research on categorization, we propose that people consider locations within a state to be part of the same superordinate category, but consider locations in two different states to be parts of different superordinate categories. The border bias occurs because people apply state-based categorization to events that are not governed by human-made boundaries. Such categorization results in state borders being considered physical barriers that can keep disasters at bay. We demonstrated the border bias for different types of disasters (earthquake, environmental risk) and tested the underlying process in three studies. PMID:20943938

  18. Imagining and Imaging Borders: Understanding Borderlands for Global Sustainability

    NASA Astrophysics Data System (ADS)

    Konrad, V.

    2013-11-01

    Borders are increasingly complex human responses and social constructions in a world where globalizing forces confront basic human concerns for security and certainty. In an effort to provide a background to assess research directions for imaging borders, this paper explores what we know about borders, and what we do not know well about borders. Borders in globalization are the meeting points of globalizing forces of security, trade and migration flows with emerging technologies, self determination and regionalization around the world. We need to know more about how: self determination fuels secessions and new borders; borders result from complex rather than simple policy and governance issues; borders depend on the political clout of borderland communities; market and migration flows impact borders; and borders are always in motion. The paper shows how these organizing principles underlie the basic themes of border governance, flows, culture, history, security and sustainability. Finally, the paper offers two brief illustrations of border imaging to link this presentation to the following discussion of the workshop.

    This report outlines a planning approach taken by a Federal Government partnership that is meant to promote sustainable development in the future, integrating both sides of the United States-Mexican border. The twin-city area of Nogales, Ariz., and Nogales, Sonora, Mexico, known collectively as Ambos (both) Nogales, has a common borderland history of urban growth presumably based on changes in policy and economic incentives. We document changes over time in an attempt to identify colonia development and settlement patterns along the border, combining a community-participation approach with a remote-sensing analysis, to create an online mapping service.

    Saudi Arabia has borders covering over 4,300 km that are shared with seven countries. Such large borders pose many challenges for security and patrol. Thermal imagers are considered the most reliable means of threat detection, however, they are quite costly, which can prevent using them over large areas. This work discusses a multi-sensor acoustic and optical implementation for threat detection as an effort to reduce system cost. The acoustic sensor provides position and direction recognition by using a four microphone setup. The data analysis of field tests will be discussed in this work.

    Suñol, R; Garel, P; Jacquerye, A

    2009-01-01

    Citizens are increasingly crossing borders within the European Union (EU). Europeans have always been free to travel to receive care abroad, but if they wished to benefit from their statutory social protection scheme, they were subject to their local or national legislation on social protection. This changed in 1991 with the European Court of Justice defining healthcare as a service, starting a debate on the right balance between different principles in European treaties: movement of persons, goods and services, versus the responsibility of member states to organise their healthcare systems. Simultaneously, cross-border cooperation has developed between member states. In this context, patient mobility has become a relevant issue on the EU’s agenda. The EU funded a number of Scientific Support to Policies (SSP) activities within the Sixth Framework Programme, to provide the evidence needed by EU policy makers to deal with issues that European citizens face due to enhanced mobility in Europe. One SSP project “Methods of Assessing Response to Quality Improvement Strategies” (MARQuIS), focused on cross-border care. It aimed to assess the value of different quality strategies, and to provide information needed when: (1) countries contract care for patients moving across borders; and (2) individual hospitals review the design of their quality strategies. This article describes the European context related to healthcare, and its implications for cross-border healthcare in Europe. The background information demonstrates a need for further research and development in this area. PMID:19188459

    2014-11-01

    The European Union (EU) Decision (1082/2013/EU) on serious cross border threats to health was adopted by the European Parliament in November 2013, in recognition of the need to strengthen the capacity of Member States to coordinate the public health response to cross border threats, whether from biological, chemical, environmental events or events which have an unknown origin. Although mechanisms have been in place for years for reporting cross border health threats from communicable diseases, this has not been the case for incidents involving chemicals and/or environmental events. A variety of collaborative EU projects have been funded over the past 10 years through the Health Programme to address gaps in knowledge on health security and to improve resilience and response to major incidents involving chemicals. This paper looks at the EU Health Programme that underpins recent research activities to address gaps in resilience, planning, responding to and recovering from a cross border chemical incident. It also looks at how the outputs from the research programme will contribute to improving public health management of transnational incidents that have the potential to overwhelm national capabilities, putting this into context with the new requirements as the Decision on serious cross border threats to health as well as highlighting areas for future development.

    The California-Mexico border region provides an opportunity to evaluate the characteristics of the emission processes in rapidly expanding urban areas where intensive international trade and commerce activities occur. Intense anthropogenic activities, biomass burning, as well as biological and geological sources significantly contribute to high concentration levels of particulate matter (PM), polycyclic aromatic hydrocarbons (PAHs), nitrogen oxides (NOx), volatile organic compounds (VOCs), air toxics, and ozone observed in the California-US Baja California-Mexico border region. The continued efforts by Mexico and US for improving and updating the emissions inventories in the sister cities of San Diego-Tijuana and Calexico-Mexicali has helped to understand the emission processes in the border region. In addition, the recent Cal-Mex 2010 field campaign included a series of measurements aimed at characterizing the emissions from major sources in the California-Mexico border region. In this work we will present our analyzes of the data obtained during Cal-Mex 2010 for the characterization of the emission sources and their use for the evaluation of the recent emissions inventories for the Mexican cities of Tijuana and Mexicali. The developed emissions inventories will be implemented in concurrent air quality modeling efforts for understanding the physical and chemical transformations of air pollutants in the California-Mexico border region and their impacts.

  5. Rift border system: The interplay between tectonics and sedimentation in the Reconcavo basin, northeastern Brazil

    1995-11-01

    A geometric and depositional model is proposed to explain the tectonic and sedimentary evolution of the main border of the Reconcavo basin. The architecture of the rift margin is characterized by a rift border system constituted by (1) a master fault, (2) a step, and (3) a clastic wedge. This footwall-derived clastic wedge is interpreted as alluvial fans and fan deltas composed of conglomerates that interfinger with hanging-wall strata. The analysis of the vertical distribution of coarse-grained components of this wedge suggests that its composition is geographically controlled, and no regular inverted stratigraphy is commonly described for this type of succession. During an initial lacustrine phase, turbidites accumulated farther from and parallel to the rift margin. The mapping of marker beds that bound these lacustrine turbidite deposits may be used to infer major periods of clastic influx and, therefore, to correlate with periods of fault-related subsidence or climatic fluctuations in the depositional basin and erosion of the sediment source area. Periods of limited back-faulting and basin expansion toward the main border are distinguished through patterns of progradation and aggradation indicating progressive retreat of the rift border and younging; in the footwall direction. The overall evolution of the rift border seems to be related to extension, block rotation, hanging-wall subsidence, and footwall uplift associated with the initial master fault, with limited propagation of faults away from the basin into the footwall.

    Astronomers Without Borders (AWB) brings together astronomy enthusiasts of all types - amateur astronomers, educators, professionals and "armchair" astronomers for a variety of online and physicalworld programs. The AWB web site provides social networking and a base for online programs that engage people worldwide in astronomy activities that transcend geopolitical and cultural borders. There is universal interest in astronomy, which has been present in all cultures throughout recorded history. Astronomy is also among the most accessible of sciences with the natural laboratory of the sky being available to people worldwide. There are few other interests for which people widely separated geographically can engage in activities involving the same objects. AWB builds on those advantages to bring people together. AWB also provides a platform where projects can reach a global audience. AWB also provides unique opportunities for multidisciplinary collaboration in EPO programs. Several programs including The World at Night, Global Astronomy Month and others will be described along with lessons learned.

    A two-year old, male entire Border collie was presented with a one-year history of exercise-induced collapsing on the pelvic limbs. Physical examination revealed generalised muscle atrophy. Neurological examination supported a generalised neuromuscular disorder. Electromyography revealed spontaneous electrical activity in almost all muscles. Unfixed and formaldehyde-fixed biopsy samples were collected from the triceps brachii, longissimus and vastus lateralis muscles. Histopathological, histochemical and ultrastructural examinations of biopsy specimens were consistent with either centronuclear or myotubular myopathy. The dog clinically improved with supportive treatment with L-carnitine, co-enzyme Q10 and vitamin B compound. To the authors' knowledge, this is the first report of centronuclear/myotubular myopathy in a Border collie. PMID:23013377

    The remote sensing technology has many practical applications in different fields of science and industry. There is also a need to examine its usefulness for the purpose of land border surveillance. This research started with analysis of potential direct use of Earth Observation technology for monitoring migrations of people and preventing smuggling. The research, however, proved that there are still many fields within which the EO technology needs to be improved. From that point the analysis focused on improving Border Permeability Index which utilizes EO techniques as a source of information. The result of BPI analysis with use of high resolution data provides new kind of information which can support and make more effective work of authorities from security domain.

    Ambient air measurements collected from 1994 to 1995 were used in a preliminary assessment of potential source and spatial influences in the Ambos Nogales border region (Nogales, Arizona, USA and Nogales, Sonora, Mexico). In this assessment, volatile organic compounds (VOC) and particulate matter (PM) species were used from four sites, two on either side of the border. An examination of median levels and principal component analysis indicated the dominance of soil dusts and mobile sources. Pairwise comparisons of sites for VOCs associated with mobile sources revealed statistically significant differences between sites in the central Nogales area vs. the two sites furthest from the border. Particulate lead at Mexican sites was higher and significantly different vs. US sites. Although further analyses are necessary, findings suggest that local and immediate mobile/other anthropogenic and soil dust influences are present throughout Nogales, with particulate lead from leaded motor vehicle exhaust or soldering operations being a possible influence on the Mexican side.

    Territorial subdivisions and geographic borders are essential for understanding phenomena in sociology, political science, history, and economics. They influence the interregional flow of information and cross-border trade and affect the diffusion of innovation and technology. However, it is unclear if existing administrative subdivisions that typically evolved decades ago still reflect the most plausible organizational structure of today. The complexity of modern human communication, the ease of long-distance movement, and increased interaction across political borders complicate the operational definition and assessment of geographic borders that optimally reflect the multi-scale nature of today's human connectivity patterns. What border structures emerge directly from the interplay of scales in human interactions is an open question. Based on a massive proxy dataset, we analyze a multi-scale human mobility network and compute effective geographic borders inherent to human mobility patterns in the United States. We propose two computational techniques for extracting these borders and for quantifying their strength. We find that effective borders only partially overlap with existing administrative borders, and show that some of the strongest mobility borders exist in unexpected regions. We show that the observed structures cannot be generated by gravity models for human traffic. Finally, we introduce the concept of link significance that clarifies the observed structure of effective borders. Our approach represents a novel type of quantitative, comparative analysis framework for spatially embedded multi-scale interaction networks in general and may yield important insight into a multitude of spatiotemporal phenomena generated by human activity.

    2009-01-01

    The sister-city area of Nogales, Arizona, and Nogales, Sonora, Mexico, is known collectively as Ambos (both) Nogales. This area was historically one city and was administratively divided by the Gadsden Purchase in 1853. These arid-lands have limited and sensitive natural resources. Environmental planning can support sustainable development to accommodate the predicted influx of population. The objective of this research is to quantify the amount of predicted urban growth for the Ambos Nogales watershed to support future planning for sustainable development. Two modeling regimes are explored. Our goal is to identify possible growth patterns associated with the twin-city area as a whole and with the two cities modeled as separate entities. We analyzed the cross-border watershed using regression analysis from satellite images from 1975, 1983, 1996, and 2002 and created urban area classifications. We used these classifications as input to the urban growth model, SLEUTH, to simulate likely patterns of development and define projected conversion probabilities. Model results indicate that the two cities are undergoing very different patterns of change and identify locations of expected growth based on historical development. Growth in Nogales, Arizona is stagnant while the urban area in Nogales, Sonora is exploding. This paper demonstrates an application that portrays how future binational urban growth could develop and affect the environment. This research also provides locations of potential growth for use in city planning.

    Geologic, geochemical, and geophysical surveys of the Rattlesnake Roadless Area in Montana identified a small area of substantiated resource potential for a low-grade stratabound copper occurrence along the northwest border of the area. A demonstrated barite (BaSO//4) resource of 45 tons and a demonstrated limestone resource suitable for cement production are present in the southern part of the roadless area. Limestone, silica in quartz veins, and sand and gravel deposits are known in the southern part of the area but similar deposits occur widely outside the study area. There is little promise for the occurrence of energy resources in the Rattlesnake Roadless Area.

    Political borders are controversial and contested spaces. In an attempt to better understand movement along and through political borders, this project applied the metaphor of a membrane to look at how people, ideas, and things ''move'' through a border. More specifically, the research team employed this metaphor in a system dynamics framework to construct a computer model to assess legal and illegal migration on the US-Mexico border. Employing a metaphor can be helpful, as it was in this project, to gain different perspectives on a complex system. In addition to the metaphor, the multidisciplinary team utilized an array of methods to gather data including traditional literature searches, an experts workshop, a focus group, interviews, and culling expertise from the individuals on the research team. Results from the qualitative efforts revealed strong social as well as economic drivers that motivate individuals to cross the border legally. Based on the information gathered, the team concluded that legal migration dynamics were of a scope we did not want to consider hence, available demographic models sufficiently capture migration at the local level. Results from both the quantitative and qualitative data searches were used to modify a 1977 border model to demonstrate the dynamic nature of illegal migration. Model runs reveal that current US-policies based on neo-classic economic theory have proven ineffective in curbing illegal migration, and that proposed enforcement policies are also likely to be ineffective. We suggest, based on model results, that improvement in economic conditions within Mexico may have the biggest impact on illegal migration to the U.S. The modeling also supports the views expressed in the current literature suggesting that demographic and economic changes within Mexico are likely to slow illegal migration by 2060 with no special interventions made by either government.

    The image border is a pattern free dark area around the die on the photomask serving as transition area between the parts of the mask that is shielded from the exposure light by the Reticle Masking (ReMa) blades and the die. When printing a die at dense spacing on an EUV scanner, the reflection from its image border overlaps with the edges of neighboring dies affecting CD and contrast in this area. This is related to the fact that EUV absorber stack has 1-3% reflectance for actinic light. For a 55nm thick absorber the induced CD drop at the edges is found to be 4-5 nm for 27 nm dense lines. In this work we will show an overview of the absorber reflection impact on CD at the edge of the field across EUV scanner generations, for several imaging nodes and multiple absorber heights. Increasing spacing between dies on the wafer would prevent the unwanted exposure but results in an unacceptable loss of valuable wafer real estate thereby reducing the yield per wafer and is thus not a viable manufacturing solution. In order to mitigate the reflection from the image border one needs to create a so called black border. The most promising approach is removal of the absorber and the underlying multilayer down to the low reflective LTEM substrate by multilayer etching. It was shown in the previous study that the impact on CD was reduced essentially for 27 nm dense lines exposed on ASML NXE:3100. In this work we will continue the study of a multilayer etched black border impact on imaging. In particular, 22 nm lines/spaces imaging on ASML NXE:3300 EUV scanner will be investigated in the areas close to the black border as well as die to die effects. We will look closer into the CD uniformity impact by DUV Out-of-Band light reflected from black border and its mitigation. A possible OPC approach will also be evaluated.

    Background The U.S.-Mexico border displays elevated rates of hazardous alcohol and drug use. Whether the co-occurrence of alcohol and drug use and disorders is also high in the border area is unknown. Methods Data are from the U.S.-Mexico Study on Alcohol and Related Conditions, a cross-sectional survey of randomly selected respondents interviewed from 2011–2013. Participants included 1,690 Mexican Americans from Texas (572 in an off-border city and 1,118 from 3 border cities) and 1,293 Mexicans from Nuevo Leon and Tamaulipas (415 in an off-border city and 878 from 3 Mexican cities bordering Texas) who reported drinking in the last 12 months. Participants were interviewed regarding the prevalence of and risk factors for: a) co-occurring hazardous alcohol use (5+/4+ at least monthly) and drug use (medical and illicit), and b) co-occurring presence of a DSM-5 alcohol use disorder (AUD) and 2 symptoms (hazardous use and quit/control) of drug use disorders (DUD symptoms). Results Co-occurring hazardous alcohol and drug use was more common in the U.S. border cities (14.7%) than off-border (7.2%), but similar for Mexican border (1.2%) and off-border (1.4%) cities. Co-occurrence of AUD and DUD symptoms was likewise more common at the U.S. border (6.8%) than off-border (3.3%), as well as at the Mexican border (1.3%), compared to off-border (0.6%), but not statistically significant for Mexico. In models adjusting for demographics, mobility factors and exposure to the U.S. culture, border residence in both countries related to a nearly two-fold increase in prevalence ratios (PR) of co-occurring AUD and DUD symptoms (PR=1.97, 95%CI=1.36–2.85). Conclusions Increased rates of co-occurring alcohol and drug use disorders suggest an added negative impact on already difficult conditions of the border population. PMID:25833029

  3. The impact of summer rainfall on the temperature gradient along the United States-Mexico border

    The international border running through the Sonoran Desert in southern Arizona and northern Sonora is marked by a sharp discontinuity in albedo and grass cover. The observed differences in surface properties are a result of long-term, severe overgrazing of the Mexican lands. Recently, investigators have shown the Mexican side of the border to have higher surface and air temperatures when compared to adjacent areas in the United State. The differences in temperatures appear to be more associated with differential evapotranspiration rates than with albedo changes along the border. In this study, the impact of summer rainfall on the observed seasonal and daily gradient in maximum temperature is examined. On a seasonal time scale, the temperature gradient increases with higher moisture levels, probably due to a vegetative response on the United States' side of the border; at the daily level, the gradient in maximum temperature decreases after a rain event as evaporation rates equalize between the countries. The results suggest that temperature differences between vegetated and overgrazed landscapes in arid areas are highly dependent upon the amount of moisture available for evapotranspiration.

    Home to about 15 million people, the US-Mexico border area has suffered stresses from increased border security efforts and a costly drug war in Mexico. Whether immigration patterns add to increasing levels of anxiety for the Mexican population and the Mexican-origin individuals living in the US-Mexico border and near the border is unknown. We used the US-Mexico Study on Alcohol and Related Conditions (UMSARC), a cross-sectional survey (2011–2013) of individuals living in border and non-border cities of the US (n=2,336) and Mexico (n=2,460). In Mexico respondents were asked if they ever migrated to the US or have a family member living in the US (328) or not (2,124), while in the US respondents were asked if they were born in Mexico (697), born in the US with no US-born parents (second generation, 702) or born in the US with at least one US-born parent (third generation, 932). The prevalence and risk factors for symptoms of anxiety using the Beck Anxiety Inventory (>=10) were obtained. Mexicans with no migrant experience had a prevalence of anxiety and adjusted prevalence ratio (PR) within the last month of 6.7% (PR=reference), followed by Mexicans with migration experience of 13.1% (PR=1.8), Mexican-born respondents living in the US of 17.3% (PR=2.6), US born Mexican-Americans of 2nd generation of 18.6% (PR=3.3) and finally US born 3rd+ generation of 25.9% (PR=3.8). Results help to identify regions and migration patterns at high risk for anxiety and may help to unravel causal mechanisms that underlie this risk. PMID:25543519

    Recent scholarship suggests a significant association between cross-border ties, or ties maintained with family and friends in countries and communities of origin, and the mental health of immigrants and their descendants. To date, this research has been exclusively cross-sectional, precluding conclusions about a causal association between cross-border ties and mental health outcomes. In the present study we undertake a longitudinal analysis of the relationship between cross-border ties and depression measured over a ten-year period for a sample of immigrant and U.S.-born Latinos. Data are from the Sacramento Area Latino Study on Aging (1998-2008), a population-based, prospective study of Latin American-origin adults 60 years and older. We find that cross-border ties reported at baseline were significantly associated with depression in subsequent study waves, even after controlling for the presence of depression at baseline, albeit with substantial differences by gender and nativity. Specifically, communication with family and friends in Latin America and travel to Latin America at baseline were each significantly associated with greater odds of depression for immigrant women, but with lower odds of depression for U.S.-born Latina women over the study period. Travel to Latin America at baseline was significantly associated with lower odds of depression for Latino men across the study. Across all models we control for depressive symptomatology at baseline to account for the reciprocal nature of depressive symptoms and engagement with social ties, including cross-border ties. Our findings suggest that cross-border ties may represent a unique source of both resilience and risk for the long-term mental health of immigrant Latinos and their descendants. PMID:27239901

  11. Evaluation of Border Entry Screening for Infectious Diseases in Humans

    Antão, Catarina; Hall, Robert

    2015-01-01

    In response to the severe acute respiratory syndrome (SARS) pandemic of 2003 and the influenza pandemic of 2009, many countries instituted border measures as a means of stopping or slowing the spread of disease. The measures, usually consisting of a combination of border entry/exit screening, quarantine, isolation, and communications, were resource intensive, and modeling and observational studies indicate that border screening is not effective at detecting infectious persons. Moreover, border screening has high opportunity costs, financially and in terms of the use of scarce public health staff resources during a time of high need. We discuss the border-screening experiences with SARS and influenza and propose an approach to decision-making for future pandemics. We conclude that outbreak-associated communications for travelers at border entry points, together with effective communication with clinicians and more effective disease control measures in the community, may be a more effective approach to the international control of communicable diseases.

    Background In August 2010, a tamper-resistant formulation of controlled-release oxycodone (OxyContin-OP) was introduced in the United States but not in Canada. Our objective was to determine whether introduction of OxyContin-OP in the United States influenced prescription volumes for the original controlled-release oxycodone formulation (OxyContin) at Canadian pharmacies near the international border. Methods We conducted a population-based, serial, cross-sectional study of prescriptions dispensed from pharmacies in the 3 cities with the highest volume of US–Canada border crossings in Ontario: Niagara Falls, Windsor and Sarnia. We analyzed data on all outpatient prescriptions for OxyContin dispensed by Canadian pharmacies near each border crossing between 2010 Apr. 1 and 2012 Feb. 29. We calculated and compared monthly prescription rates, adjusted per 1000 population and stratified by tablet strength. Results The number of tablets dispensed near 4 border crossings in the 3 Canadian cities remained stable over the study period. However, the rate of dispensing at pharmacies near the Detroit–Windsor Tunnel increased roughly 4-fold between August 2010 and February 2011, from 505 to 1969 tablets per 1000 population. By April 2011, following warnings to prescribers and pharmacies regarding drug-seeking behaviour, the dispensing rate declined to 1683 tablets per 1000 population in this area. By November 2011, the rate had returned to levels observed in early 2010. Our analyses suggest that 242 075 excess OxyContin tablets were dispensed near the Detroit–Windsor Tunnel between August 2010 and October 2011. Conclusions Prescribing of the original formulation of controlled-release oxycodone rose substantially near a major international border crossing following the introduction of a tamper-resistant formulation in the United States. It is possible that the restriction of this finding to the area surrounding the Detroit–Windsor Tunnel reflects specific

    2015-01-01

    Background Dermoscopy is a highly effective and noninvasive imaging technique used in diagnosis of melanoma and other pigmented skin lesions. Many aspects of the lesion under consideration are defined in relation to the lesion border. This makes border detection one of the most important steps in dermoscopic image analysis. In current practice, dermatologists often delineate borders through a hand drawn representation based upon visual inspection. Due to the subjective nature of this technique, intra- and inter-observer variations are common. Because of this, the automated assessment of lesion borders in dermoscopic images has become an important area of study. Methods Fast density based skin lesion border detection method has been implemented in parallel with a new parallel technology called WebCL. WebCL utilizes client side computing capabilities to use available hardware resources such as multi cores and GPUs. Developed WebCL-parallel density based skin lesion border detection method runs efficiently from internet browsers. Results Previous research indicates that one of the highest accuracy rates can be achieved using density based clustering techniques for skin lesion border detection. While these algorithms do have unfavorable time complexities, this effect could be mitigated when implemented in parallel. In this study, density based clustering technique for skin lesion border detection is parallelized and redesigned to run very efficiently on the heterogeneous platforms (e.g. tablets, SmartPhones, multi-core CPUs, GPUs, and fully-integrated Accelerated Processing Units) by transforming the technique into a series of independent concurrent operations. Heterogeneous computing is adopted to support accessibility, portability and multi-device use in the clinical settings. For this, we used WebCL, an emerging technology that enables a HTML5 Web browser to execute code in parallel for heterogeneous platforms. We depicted WebCL and our parallel algorithm design. In

    Soil erosion plays an important role in sediment and carbon storage within, and exports from, catchments. In cultivated landscapes, field borders can improve the temporary storage of eroded soil particles and associated carbon, by impeding lateral soil fluxes. These local soil accumulations can lead to the development of linear landforms (such as headlands and lynchets) which will keep evolving after field border removal. A recent study performed in a representative cultivated hillslope of the SW Parisian Basin showed that 39% of the area corresponds to landforms resulting from soil accumulation induced by former and present field borders. This study demonstrated that field borders influence greatly the landscape morphology, but also the spatial distribution of soil thickness, and locally the A-horizon thickness, which are essential parameters for the prediction of SOC stocks. This study aims at characterizing and quantifying the effect of field borders and their removal on medium term topsoil erosion and deposition rates in a cultivated hillslope of the SW Parisian Basin, consolidated in 1967. Here, we used the Cs-137 technique to assess recent patterns of soil redistribution. We measured the Cs-137 inventories of 68 soil cores sampled along transects covering the area and, more specifically, linear landforms identified along present and past field borders (i.e., lynchet and undulation landforms, respectively). Then, we used a spatially-distributed Cs-137 conversion model that simulates and discriminates soil redistribution induced by water and tillage erosion processes over the last fifty years. Finally, observations and model outputs were confronted. Our results show that tillage erosion dominate the soil redistribution in the study area for the 1954-2009 period and generated about 95% (i.e., 4.50 Mg.ha-1.yr-1) of the total gross erosion. Soil redistribution was largely affected by the presence of current and former field borders, where hotspots areas of

    Strips of fallow vegetation along cropland borders are an effective strategy for providing brood habitat for declining populations of upland game birds (Order: Galliformes), including northern bobwhite (Colinus virginianus), but fallow borders lack nectar-producing vegetation needed to sustain many beneficial insect populations (e.g., crop pest predators, parasitoids, and pollinator species). Planted borders that contain mixes of prairie flowers and grasses are designed to harbor more diverse arthropod communities, but the relative value of these borders as brood habitat is unknown. We used groups of six human-imprinted northern bobwhite chicks as a bioassay for comparing four different border treatments (planted native grass and prairie flowers, planted prairie flowers only, fallow vegetation, or mowed vegetation) as northern bobwhite brood habitat from June-August 2009 and 2010. All field border treatments were established around nine organic crop fields. Groups of chicks were led through borders for 30-min foraging trials and immediately euthanized, and eaten arthropods in crops and gizzards were measured to calculate a foraging rate for each border treatment. We estimated arthropod prey availability within each border treatment using a modified blower-vac to sample arthropods at the vegetation strata where chicks foraged. Foraging rate did not differ among border treatments in 2009 or 2010. Total arthropod prey densities calculated from blower-vac samples did not differ among border treatments in 2009 or 2010. Our results showed plant communities established to attract beneficial insects should maximize the biodiversity potential of field border establishment by providing habitat for beneficial insects and young upland game birds.

    Nearly one-third of the world's population is infected with latent tuberculosis (LTBI). Tuberculosis (TB) rates in the border states are higher than national rates in both the US and Mexico, with the border accounting for 30% of total registered TB cases in both countries. However, LTBI rates in the general population in Mexican border states are unknown. In this region, LTBI is diagnosed using the tuberculin skin test (TST). New methods of detection more specific than TST have been developed, although there is currently no gold standard for LTBI detection. Our objective is to demonstrate utility of the Quantiferon TB gold In-Tube (QFT-GIT) test compared with the TST to detect LTBI among border populations. This is an observational, cross-sectional study carried out in border areas of the states of Nuevo Leon and Tamaulipas, Mexico. Participants (n = 210) provided a TST and blood sample for the QFT-GIT. Kappa coefficients assessed the agreement between TST and QFT-GIT. Participant characteristics were compared using Fisher exact tests. Thirty-eight percent of participants were diagnosed with LTBI by QFT-GIT. The proportion of LTBI detected using QFT-GIT was almost double [38% (79/210)] that found by TST [19% (39/210)] (P < 0.001). Concordance between TST and QFT-GIT was low (kappa = 0.37). We recommend further studies utilizing the QFT-GIT test to detect LTBI among border populations. PMID:26484340

    Objective To assess the prevalence of health care utilization in Mexico by Texas border residents and to identify the main contributing factors to their cross-border utilization of health care services. Data and Methods This study used primary data from a population-based telephone survey that was conducted in the whole Texas border area in 2008. The survey included responses from 1,405 adults. Multivariate logistic regression models were estimated to determine predictors of utilizing a wide range of health care services in Mexico. Principal Findings Forty-nine percent of the sample reported having ever purchased medications in Mexico, followed by 41 percent for dentist visits, 37.3 percent for doctor visits, and 6.7 percent for inpatient care. The most significant predictors of health care utilization in Mexico were lack of U.S. health insurance coverage, dissatisfaction with the quality of U.S. health care, and poor self-rated health status. Conclusions The high prevalence of use of health care services in Mexico by Texas border residents is suggestive of unmet needs in health care on the U.S. side of the border. Addressing these unmet needs calls for a binational approach to improve the affordability, accessibility, and quality of health care in the U.S.–Mexico border region. PMID:21158855

    Aim: The aim of the study is to analyze the effect of different materials and techniques in current use on peripheral shaping of complete denture impression. Methods: The present study was conducted to compare and evaluate the maxillary border morphology produced using tissue conditioner as control and low fusing impression compound, Polyether, Pattern resin and periphery wax as border molding materials. The study was carried out on 15 denture wearer patients with well formed, rounded edentulous maxillary arch with adequate width and height. On each patient, border moldings were done, with tissue conditioner which was loaded on the borders of previous maxillary denture of the patient (control group), low fusing impression compound (Group 1), polyether (Group 2), Pattern resin (Group 3) and Peripheral wax (Group 4), respectively on special tray made for the patient. Sulcus width height and area was then measured for each group using stereomicroscope. Results and Conclusions: Based on the study it is concluded that the polyether was the best material for border molding which will give most accurate borders to a denture. PMID:26929495

    Photomask is at the heart of a lithographic scanner's optical path. It cannot be left non-optimized from the imaging point of view. In this work we provide new insights on two critical aspects of EUV mask architecture: optimization of absorber for 16 nm half-pitch imaging and a systematic approach to black border EUV and DUV reflectance specifications. Good 16 nm imaging is demonstrated on ASML NXE:3300 EUV scanner. Currently a relatively high dose resist is used for imaging and the dose reduction is desired. Optimization (reduction) of absorber height and mask CD bias can allow for up to 30% dose reduction without essential contrast loss. Disadvantages of absorber height reduction are ~7 nm increase of best focus range through pitch and tighter absorber height mean to target and uniformity requirements. A disadvantage of a smaller reticle CD (down to 14 nm 1x) is manufacturing process uniformity over the reticle. A systematic approach of black border reflections impact on imaging is established. The image border is a pattern free dark area surrounding the image field and preventing exposure of the image field neighborhood on wafer. Currently accepted design of the black border on EUV reticle is an image border where the absorber and multilayer stack are etched down to the substrate and EUV reflectance is reduced to <0.05%. DUV reflectance of such a black border is about 5%. It is shown that a tighter DUV reflectance specification <1.5% is required driven by the impact of DUV reflections from the black border on imaging. NXE:3300 and NXE:3100 experimental imaging results are shown. The need of low DUV wavelength reflectance metrology (in the range 100-300 nm) is demonstrated using an estimated NXE scanner out-of-band DUV spectrum. Promising results of low DUV reflectance of the black border are shown.

  3. Building the Tower of Babel: cross-border urgent medical assistance in Belgium, Germany and The Netherlands.

    The border area between Germany, Belgium, and The Netherlands includes a substantial number of cooperative forms in the urgent medical assistance sector. Collaboration usually takes place in densely populated areas with cities or villages situated on or in proximity to the border. In some regions, definitive borders are not apparent to the extent that inhabitants often times are unaware of their existence. The border may pass directly through a built-up area with intense cross-border activity due to population residency, place of work, shopping, and recreational pursuits. To obtain a deeper insight into cross-border Urgent Medical Assistance (UMA), the Ministry of the Interior and Kingdom Relations (IKR) and the Ministry for Health, Welfare, and Sports (HWS) in The Netherlands commissioned research into cross-border UMA impediments and solutions at administrative, judicial, and operational level. The following central questions were presented for research: (1) What opportunities and impediments are presented in the area of cross-border, urgent medical assistance at administrative, legal, operational, and equipment employable level?; and (2) Which solutions may be submitted to tackle existing impediments? Two techniques were employed to answer the research questions. First, relevant documents were studied from extensive file and literature searches. File and literature search findings subsequently were tested in practice through interviews with relevant experts. Dutch ambulance services provide support to both their Belgian and German counterparts and vice versa. In the instance of cross-border ambulance deployment, relevant assistance services are subject to due observance of various legislations and regulations. Such regulations may restrict effective and efficient deployment of personnel and equipment at critical moments, because regulation discrepancies may arise over ambulance personnel's authorities, ambulance content, and deployment sequence.

  4. CHIPS: Monitoring Colonias Along the United States-Mexico Border in Texas

    2008-01-01

    Colonias, which are unincorporated border settlements in the United States, have emerged in rural areas without the governance and services normally provided by local government. The expansion of colonias in the United States-Mexico border region can be traced to the rapid growth associated with the Mexican Border Industrial Program during the 1960s. This rapid population growth created a lack of affordable housing, causing new migrants in the United States to purchase rural homestead lots through a contract-for-deed program from land developers. Because of the need to keep prices affordable and the absence of effective land-use controls, these homesteads expanded into rural subdivisions, commonly called colonias, without proper infrastructure. Colonias have been identified in the four U.S. border states, with Texas having designated the majority, which numbered over 1,400 colonias in 2001. Because the region is binationally interconnected economically, politically, and socially, the phenomenon of colonias in the United States is a transborder issue.

  5. Fatal footsteps: murder of undocumented border crossers in Maricopa County, Arizona.

    Fulginiti, Laura C

    2008-01-01

    In the past 5 years, the mortality rate among undocumented workers in Arizona has increased steadily. In 1998-1999, the number of deaths among border crossers was 28. That number increased dramatically in 1999-2000 to 106 and has exceeded 200 in each of the past 2 years. In the past, many immigrant deaths occurred as a result of dehydration and exposure (1). More recently, a new trend has emerged, that is, death of border crossers at the hands of the persons ("coyotes") hired to lead them across the border to safety. In some cases, the smugglers attempt to extort additional money from the families by holding the victims hostage once they have crossed the border into the United States. If the families fail to pay, the hostage is killed. Rival gangs are also murdering one another over their human cargo. Nine recent cases illustrate this trend in Maricopa County. In each example, the victims were bound, shot (or in one instance stabbed) and dumped in a remote desert area. All of the decedents were linked to murder for extortion by the ''coyotes'' or rival gang members. PMID:18279237

    Environmental health and environmental quality issues along the U.S.-Mexico border have been of concern for several years. The enactment of the North American Free Trade Agreement and the presence of the maquiladoras (foreign-owned industries using imported raw materials) have intensified those concerns recently. Efforts to assess these issues are complicated by the fact that many of the issues affecting the border region are within federal jurisdiction, but the problems are regional and local in nature. Thus, state and local governments become involved with public concerns about real and potential problems. One major problem is that environmental health data from this region are lacking, particularly from Mexico. Some new agencies such as the Border Environment Cooperation Commission, the United States-Mexico Border Health Commission, and the North American Commission on Environmental Cooperation have joined several existing agencies at the federal and state level to address environmental quality and health. Several studies have been initiated to determine air and water quality, but little is being done in the areas of hazardous waste and health assessment. Several problems are anticipated in the generation of such data, such as its format and accessibility. Data gaps and research needs are discussed. PMID:8793340

    The artemisinin (ART), discovered in China, has been widely used against malaria in China over the last 30 years. Understanding the emergence and origin of ART resistance in China is therefore of great interest. We analyzed 111 culture-adapted isolates of P. falciparum from China-Myanmar (CM) border for their susceptibility to dihydroartemisinin using the ring stage survival assay (RSA0−3h) and genotyped their K13 genes. Of the isolates, 59 had a wild type of the K13 marker and a median ring survival rate of 0.26% (P95 = 1.005%). Among the remaining isolates harboring single mutations in the K13 marker, 26 survived at >P95(median survival rate = 2.95%). Further, we genotyped the K13 gene of 693 isolates collected from different regions in China and China-Myanmar/Thai-Cambodia/Thai-Myanmar (CM/TC/TM) borders, 308 (44.4%) had K13 mutations and marked differences in the patterns of K13 mutations were observed between the CM and the TC/TM borders. A network diagram showed that majority of the K13 mutant alleles from the CM border clustered together including those harboring the high resistant-associated R539T mutations. The resistant parasites carrying distinct halplotypes suggested the multiple indigenous origins of the resistant alleles, which highlight the importance of surveillance of resistance in all malaria endemic areas where ART has been introduced.

    2004-12-01

    During the last 12 years the European Union (EU) has financed the new member applicant countries of Central and Eastern Europe in their preparation for joining the EU. Based on this enlargement of the EU, funding for Cross Border Protection has been made available from the overall infrastructure improvement budget. Border protection was required in areas where border conflicts had taken place and to limit Illegal Immigration (II) and smuggling. After 9/11/2001, defence against terrorist activities will no doubt be added to the requirement. This paper describes the approach taken in the design of the latest "containerised" police and para military Mobile Surveillance Units (MSUs). This approach may also be considered for Homeland Security initiatives. These MSU's utilise standard road vehicles, and off-road variants, converted to use high performance military thermal imagers, such as SiGMA. In future the current, in service, MSUs will require increased sensor integration and networking to cover land and coastal borders. The underlying key is affordability for the police and para-military markets whilst retaining the highest performance derived from the latest SFPA military standard thermal imagers.

  12. Simulation of Cross-border Impacts Resulting from Classical Swine Fever Epidemics within the Netherlands and Germany.

    The cross-border region of the Netherlands (NL) and the two German states of North Rhine Westphalia (NRW) and Lower Saxony (LS) is a large and highly integrated livestock production area. This region increasingly develops towards a single epidemiological area in which disease introduction is a shared veterinary and, consequently, economic risk. The objectives of this study were to examine classical swine fever (CSF) control strategies' veterinary and direct economic impacts for NL, NRW and LS given the current production structure and to analyse CSF's cross-border causes and impacts within the NL-NRW-LS region. The course of the epidemic was simulated by the use of InterSpread Plus, whereas economic analysis was restricted to calculating disease control costs and costs directly resulting from the control measures applied. Three veterinary control strategies were considered: a strategy based on the minimum EU requirements, a vaccination and a depopulation strategy based on NL and GER's contingency plans. Regardless of the veterinary control strategy, simulated outbreak sizes and durations for 2010 were much smaller than those simulated previously, using data from over 10 years ago. For example, worst-case outbreaks (50th percentile) in NL resulted in 30-40 infected farms and lasted for two to four and a half months; associated direct costs and direct consequential costs ranged from €24.7 to 28.6 million and €11.7 to 26.7 million, respectively. Both vaccination and depopulation strategies were efficient in controlling outbreaks, especially large outbreaks, whereas the EU minimum strategy was especially deficient in controlling worst-case outbreaks. Both vaccination and depopulation strategies resulted in low direct costs and direct consequential costs. The probability of cross-border disease spread was relatively low, and cross-border spread resulted in small, short outbreaks in neighbouring countries. Few opportunities for further cross-border harmonization and

  13. Usability in Public Services and Border Control

    Pirelli, Giuliano

    The paper starts with a brief overview of the scale of disability and associated challenges and puts them in the context of the public policy on disability. It then analyses the usability challenges in public services and border control, including the issues of accessibility, safety and communication. These need to be addressed in future policy proposals, to provide the best assistance by new technologies to elderly people and people with disabilities, avoiding creating new barriers due to incorrect or incomplete initial conception. With increasing flux of novel security technology in mass transportation systems, and particularly the use of biometric identification in airports, the challenge of usability is recognized. This paper analyses these issues in the context of users with disability in an idealized process of Simplifying Passenger Travel (SPT).

  12. Superior border versus inferior border fixation in displaced mandibular angle fractures: prospective randomized comparative study.

    2014-07-01

    A prospective randomized comparative study was conducted to compare open reduction and internal fixation of displaced fractures (>2mm) via intraoral approach with application of a single monocortical miniplate according to Champy's ideal line of osteosynthesis (group A) versus an extraoral approach with application of an inferior border plate with at least two holes (bicortical screws) on either side of the fracture line (group B). Clinical and radiographic assessment was done preoperatively, immediately postoperative, and at 1, 4, and 12 weeks of follow-up. Parametric and non-parametric data were evaluated by independent samples t-test and χ(2) analysis, respectively; P<0.05 was considered statistically significant. There was no significant difference between the two groups with regard to complication rates, although functional outcomes including pain (visual analogue scale score) at the 1-week follow-up and inter-incisal mouth opening at the 12-week follow-up were found to be better in group B. On radiographic assessment, the inferior border was better aligned in group B than in group A, with no superior border distraction in group B. The duration of surgery was shorter in group B, and this was considered to be the easier approach for fixation of the device as assessed by the surgeons. PMID:24636170

    2015-01-01

    Background Little epidemiological evidence exists on alcohol use and related problems along the U.S.-Mexico border, although the borderlands have been the focus of recent media attention related to the escalating drug/violence “epidemic”. In the present study the relationship of proximity of living at the border and alcohol use disorders (AUDs) is analyzed from the U.S.-Mexico Study on Alcohol and Related Conditions (UMSARC). Methods Household surveys were conducted on 2,336 Mexican Americans in Texas (771 in a non-border city and 1,565 from three border cities located in the three poorest counties in the U.S.) and 2,460 Mexicans from the states of Nuevo Leon and Tamaulipas in Mexico (811 in a non-border city and 1,649 from three cities which are sister cities to the Texas border sites). Results Among current drinkers, prevalence of AUD was marginally greater (p<0.10) at the U.S. border compared to the non-border, but the opposite was true in Mexico (p<0.001), and these trends continued on both sides across volume and 5+ drinking days. Prevalence was greater in Laredo/Nuevo Laredo relative to their respective sister city counterparts on the same side. Border effects appeared greater for males than females in the U.S. and the opposite in Mexico. Conclusion The data suggest that border proximity may affect AUD in both the U.S. and Mexico, but in the opposite direction, and may be related to the relative perceived or actual stress of living in the respective communities.

    A model for drainage of a power-law fluid through a Plateau border is proposed which accounts for the actual Plateau border geometry and interfacial mobility. The non-dimensionalized Navier-Stokes equations have been solved using finite element method to obtain the contours of velocity within the Plateau border cross section and average Plateau border velocity in terms of dimensionless inverse surface viscosity and power-law rheological parameters. The velocity coefficient, the correction for the average velocity through a Plateau border of actual geometry compared to that for a simplified circular geometry of the same area of cross section, was expressed as a function of dimensionless inverse surface viscosity and flow behavior index of the power-law fluid. The results of this improved model for Plateau border drainage were then incorporated in a previously developed foam drainage model [G. Narsimhan, J. Food Eng. 14 (1991) 139] to predict the evolution of liquid holdup profiles in a standing foam. Foam drainage was found to be slower for actual Plateau border cross section compared to circular geometry and faster for higher interfacial mobility and larger bubble size. Evolution of liquid holdup profiles in a standing foam formed by whipping and stabilized by 0.1% beta-lactoglobulin in the presence of xanthan gum when subjected to 16g and 45g centrifugal force fields was measured using magnetic resonance imaging for different xanthan gum concentrations. Drainage resulted in the formation of a separate liquid layer at the bottom at longer times. Measured bubble size, surface shear viscosity of beta-lactoglobulin solutions and literature values of power-law parameters of xanthan gum solution were employed in the current model to predict the evolution of liquid holdup profile which compared well with the experimental data. Newtonian model for foam drainage for zero shear viscosity underpredicted drainage rates and did not agree with the experimental data. PMID

    The sustainable use and management of natural resources in border regions requires unambiguous geological information from neighbouring countries. However, the available data often lack compatibility and the same level of detail across borders. Various stakeholders in the Netherlands and Flanders expressed their interest to harmonize the (hydro) geological models in the shared border region. Accordingly, the first H3O project was initiated in March 2012, focussing on the Roer Valley Graben across the Dutch-Flemish border. A second project (H3O-Campine area) set off in April 2015 and deals with the adjacent Campine area. Aim of these successive projects was (is) to produce cross-border, up-to-date, three-dimensional geological and hydrogeological models of the Cenozoic deposits. Existing (hydro) geological data (boreholes, well logs, seismic data, fault traces, geological maps and models) are collected, re-interpreted according to a harmonized lithostratigraphic scheme and fed into the 3D modelling process. Results of the first H3O-Roer Valley Graben project include: • A correlation scheme between Dutch and Belgian/Flemish (hydro) geological units; • A consistent fault model of the Roer Valley Graben; • Geometrically and stratigraphically consistent geological and hydrogeological models of the Cenozoic deposits in the Roer Valley Graben across the Dutch-Flemish border. The resulting 3D models can be considered as a state-of-the-art reference for the subsurface structure of the project area and can be used as a base for cross-border management of natural resources. The correlation scheme serves as a guideline for present (H3O-Campine area) and future cross-border projects. The H3O projects are carried out by a partnership between TNO - Geological Survey of the Netherlands, VITO and the Geological Survey of Belgium. The H3O models will be available in the public domain via the online data portals of DOV (Databank Ondergrond Vlaanderen) and DINOloket (Data en

    The Bureau of Customs and Border Protection has the task of interdicting illicit radioactive material at ports of entry. Items of concern include radiation dispersal devices (RDD), nuclear warheads, and special nuclear material (SNM). The preferred survey method screens all vehicles in primary and diverts questionable vehicles to secondary. This requires high detection probability in primary while not overwhelming secondary with alarms, which could include naturally occurring radioactive material (NORM) found in acceptable cargo and radionuclides used in medical procedures. Sensitive alarm algorithms must accommodate the baseline depression observed whenever a vehicle enters the portal. Energy-based algorithms can effectively use the crude energy information available from a plastic scintillator to distinguish NORM from SNM. Whenever NORM cargo limits the alarm threshold, energy-based algorithms produce significantly better detection probabilities for small SNM sources than gross-count algorithms. Algorithms can be best evaluated using a large empirical data set to 1) calculate false alarm probabilities, 2) select sigma-level thresholds for operationally acceptable false alarm rates, and 3) determine detection probabilities for marginally detectable pseudo sources of SNM.

    The Yuma Sector Border Patrol Area is a high temperature and high solar radiation environment, providing an opportunity for the U.S. Department of Energy (DOE) to study thermal effects on outdoor light-emitting diode (LED) luminaires outside of the testing laboratory. Six LED luminaires were installed on three poles on the U.S.- Mexico border in February 2014 as part of a trial installation, which was detailed in a prior GATEWAY report.1 The initial trial installation was intended as a short - term test of six luminaires installed on three poles before proceeding with the complete installation of over 400 luminaires. Unexpected delays in the full installation have prevented the detailed evaluations initially planned, but the six installed LED luminaires continue to be monitored, and over the past year illuminance measurements were recorded initially in February 2014 and again in September 2014 at about 2500 hours of operation and in March 2015 at about 5000 hours of operation.

    Community engagement is increasingly promoted in developing countries, especially in international health research, but there is little published experience. The Shoklo Malaria Research Unit (SMRU) conducts research with refugees, migrant workers, displaced people, and day migrants on the Thai-Burmese border, and has recently facilitated the set up of the Tak Province Border Community Ethics Advisory Board (T-CAB). Valuable lessons have been learnt from consultation with the T-CAB especially in the area of participant recruitment and the informed consent process. A lot of new research questions have emerged from consultation with the T-CAB. This paper describes our experience, lessons learnt and the unique challenges faced working with the T-CAB from its initial conception to date. We conclude that consultation with the T-CAB has made improvements in our research in particular operational and ethical aspects of our studies. PMID:22984375

    Social and cultural conditions (including U.S. border and inland influence, role models within the family, and educational background) which affect locus of control and achievement motivation among Mexican entrepreneurs were explored among 64 selected entrepreneurs in two Mexican towns, one on the Mexico-U.S. border, the other located inland. Analyses showed that the border subsample scored higher on External locus of control; however, in both subsamples the father was an important element in the locus of control variable and the entrepreneur status. No statistically significant mean difference was noted for achievement motivation. Practical applications and limitations are discussed. PMID:19708411

    At the same time that health researchers have mostly ignored the cross-border nature of immigrant social networks, scholars of immigrant “transnationalism” have left health largely unexamined. This paper addresses this gap by analyzing the relationship between cross-border ties and self-rated health status for young Latino adults living in the greater Los Angeles area (n=1268). Findings based on an ordered logistic regression analysis suggest that cross-border relationships may have both protective and adverse effects on overall health status. Specifically, those reporting a period of extended parental cross-border separation during childhood have lower odds of reporting better categories of self-rated health, all else equal. Conversely, a significant positive association was found between having a close relative living abroad and self-rated health status for foreign-born respondents when interacted with immigrant generation (foreign versus U.S.-born). Given the findings of significant negative and positive relationships between cross-border ties and self-rated general health status, I discuss the implications for future research on the social determinants of immigrant health.
