Many Haitian migrants live and work as undocumented laborers in the Dominican Republic. This study examines the legacy of anti-Haitian discrimination in the Dominican Republic and association of discrimination with mental health among Haitian migrants. This study used mixed methods to generate hypotheses for associations between discrimination and mental health of Haitian migrants in the Dominican Republic. In-depth interviews were conducted with 21 Haitian and 18 Dominican community members and clinicians. One hundred and twenty-seven Haitian migrants participated in a pilot cross-sectional community survey. Instruments included culturally adapted Kreyòl versions of the Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI) and a locally developed function impairment scale. Haitian migrants described humiliation (imilyasyon) as a reason for mental distress and barrier to health care. Dominicans reported that discrimination (discriminación) was not a current social problem and attributed negative social interactions to sociocultural, behavioral, and biological differences between Dominicans and Haitians. These qualitative findings were supported in the quantitative analyses. Perceived discrimination was significantly associated with depression severity and functional impairment. Perceived mistreatment by Dominicans was associated with a 6.6-point increase in BDI score (90% confidence interval [CI]: 3.29, 9.9). Knowing someone who was interrogated or deported was associated with a 3.4-point increase in BAI score (90% CI: 0.22, 6.64). Both qualitative and quantitative methods suggest that perceived discrimination and the experience of humiliation contribute to Haitian migrant mental ill-health and limit access to health care. Future research should evaluate these associations and identify intervention pathways for both improved treatment access and reduction of discrimination-related health risk factors.

Existing literature related to HIV in the Dominican Republic has tended to neglect the unique role of tourism areas as distinct ecologies facilitative of sexual risk behavior, particularly HIV vulnerability and transmission. Furthermore, limited attention has focused on Dominican adolescents living in close proximity to tourism areas who have become increasingly exposed to alcohol due to the expanding tourism industry in the Dominican Republic. While most previous analyses of the effects of alcohol on adolescent sexual risk behavior have focused on the transient effects of alcohol on judgment and decision making, the effects of chronic alcohol use on sexual behavior has been a neglected area of research. Our study explores the relationship between chronic alcohol use, the parent-adolescent relationship, affective factors such as self-esteem, and intentions to engage in sex. We examine the above factors within the context of tourism areas which represent a unique ecology of alcohol availability and consumption and HIV risk. We discuss implications for developing applied family-based programs to target Dominican adolescent alcohol use and sexual risk behavior in tourism areas of high alcohol exposure.

This paper is a floristic and phytosociological study of the dry forest communities of the Dominican Republic. A total of 69 relevés in dry forest biotopes were carried out. The samples were subsequently subjected to Detrended Correspondence Analysis for the determination and study of possible groupings. The study does not cover tree formations growing on serpentines, nor the so-called semideciduous forests, peculiar to areas with higher rainfall. A total of nine phytocoenoses were identified. The most significant results led to the description of six new phytosociological associations: Simaroubetum berteroani (thorny dry forest on coastal dunes), Phyllostylo rhamnoidis-Prosopidetum juliflorae (southern Dominican disturbed dry forest), Consoleo moniliformis-Camerarietum linearifoliae (dry forest on hard limestones), Lemaireocereo hystricis-Prosopidetum juliflorae (northern Dominican disturbed dry forest), Lycio americani-Prosopidetum juliflorae (disturbed dry forest on saline soils) and Guettardo ellipticae-Guapiretum discoloris (dry forest on flat-topped hillocks in Montecristi). This is an important step forward in the phytosociological and floristic studies of the Caribbean territories.

Full Text Available This mixed-method study explored the social world of Haitian migrants, examining forms of social support and social stress, as well as their relationship to mental health. Among six Haitian migrant communities in the Cibao Valley of the Dominican Republic, a community-based survey (n = 127 was conducted to assess migration experiences, current stressors, mental health, and functioning. In addition, to explore perceptions and experiences of migration, social interactions, and mental health, the study drew upon in-depth interviews and free-listing activities among Haitian migrants, as well as cognitive interviews with select survey participants. Depressive, anxiety, and mental distress survey scores were associated with 1 negative social interactions (including interrogation or deportation, perceived mistreatment by Dominicans, and overcrowding and 2 lack of social support, including migrating alone. Mental distress scores were higher among women, and being married was associated with higher anxiety scores, potentially reflecting unmet social expectations. In qualitative data, participants emphasized a lack of social support, often referred to as tèt ansanm (literally meaning "heads together" in Haitian Creole or Kreyòl and roughly defined as solidarity or reciprocal social collaboration. The authors of the study propose that the practice of tèt ansanm-also termed konbit, and, in the Dominican Republic, convite-could be used as a means of facilitating positive-contact events among Haitians and Dominicans. These interactions could help counteract social stress and build social capital in settings similar to those of the study.

From the beginning of the influenza pandemic until the time the outbreak described here was detected, 77,201 cases of pandemic influenza A(H1N1) with 332 deaths had been reported worldwide, mostly in the United States and Mexico. All of the cases reported in Spain until then had a recent history of travel to Mexico, the Dominican Republic, or Chile. We describe an outbreak of influenza among medical students who traveled from Spain to the Dominican Republic in June 2009. We collected diagnostic samples and clinical histories from consenting medical students who had traveled to the Dominican Republic and from their household contacts after their return to Spain. Of 113 students on the trip, 62 (55%) developed symptoms; 39 (45%) of 86 students tested had laboratory evidence of influenza A(H1N1) infection. Most students developed symptoms either just before departure from the Dominican Republic or within days of returning to Spain. The estimated secondary attack rate of influenza-like illness among residential contacts of ill students after return to Spain was 2.1%. The attack rate of influenza A(H1N1) can vary widely depending on the circumstances of exposure. We report a high attack rate among a group of traveling medical students but a much lower secondary attack rate among their contacts after return from the trip. These findings may aid the development of recommendations to prevent influenza. © 2011 International Society of Travel Medicine.

2016-12-01

The southern coast of Dominican Republic is a very populated region, with several important cities including Santo Domingo, its capital. Important activities are rooted in the southern coast including tourism, industry, commercial ports, and, energy facilities, among others. According to historical reports, it has been impacted by big earthquakes accompanied by tsunamis as in Azua in 1751 and recently Pedernales in 2010, but their sources are not clearly identified. The aim of the present work is to develop a numerical tool to simulate the impact in the southern coast of the Dominican Republic of tsunamis generated in the Caribbean Sea. This tool, based on the Tsunami-HySEA model from EDANYA group (University of Malaga, Spain), could be used in the framework of a Tsunami Early Warning Systems due the very short computing times when only propagation is computed or it could be used to assess inundation impact, computing inundation with a initial 5 meter resolution. Numerical results corresponding to three theoretical sources are used to test the numerical tool.

Mejias, Stephanie G; Ramphul, Kamleshun

2018-02-20

Background Bronchial asthma is an important health problem worldwide. There is insufficient data on the prevalence of bronchial asthma among school children in Santo Domingo, Dominican Republic. Objective The objective of this study is to assess the prevalence of asthma and its related risk factors among school children in Santo Domingo, Dominican Republic. Materials and methods A cross-sectional study using a modified questionnaire was conducted in Santo Domingo among 600 children aged three to 11 eleven years. The prevalence of asthma and its associated risk factors such as birth order, family history of asthma, family history of allergy, exposure to pets at home, exposure to tobacco smoke, and source of fuel used at home were collected. The relevant data collected was analyzed using the Statistical Package for the Social Sciences (SPSS) 24.0. (IBM Corp., Armonk, NY) software. Results The prevalence of asthma was found to be 22.0%. Age, family history of asthma, family history of allergy, exposure to tobacco smoke, and birth order showed statistical significance. The source of fuel used at home, gender, and exposure to pets were not statistically significant to be considered as risk factors associated with asthma in the population studied. Conclusion With an asthma prevalence of 22.0% in the pediatric population, the Dominican Republic has one of the highest national rates of asthma in the pediatric population in Latin America. Proper education, screening, and prevention can help lower the burden of this disease economically and socially.

To compare empathic orientation among medical students from three schools of medicine in Colombia and one in the Dominican Republic. Empathic orientation of medical students was measured using the Jefferson Scale of Physician Empathy (JSPE), Spanish version for students (the "S" version) validated in Mexico and Chile, and culturally adapted to Colombia and the Dominican Republic. Data were compared using a three-factor analysis of variance (model III) and a discriminant analysis. No differences in empathic orientation were observed among courses and between sexes, but differences were found in schools of medicine considered as a unit in each studied country. Empathic orientation levels tend to reduce as courses advance. This was observed in both male and female students and in all schools analyzed.

Full Text Available BACKGROUND: Cesarean section is the only surgery for which we have nearly global population-based data. However, few surveys provide additional data related to cesarean sections. Given weaknesses in many health information systems, health planners in developing countries will likely rely on nationally representative surveys for the foreseeable future. The objective is to validate self-reported data on the emergency status of cesarean sections among women delivering in teaching hospitals in the capitals of two contrasting countries: Accra, Ghana and Santo Domingo, Dominican Republic (DR. METHODS AND FINDINGS: This study compares hospital-based data, considered the reference standard, against women's self-report for two definitions of emergency cesarean section based on the timing of the decision to operate and the timing of the cesarean section relative to onset of labor. Hospital data were abstracted from individual medical records, and hospital discharge interviews were conducted with women who had undergone cesarean section in two hospitals. The study assessed sensitivity, specificity, and positive predictive value of responses to questions regarding emergency versus non-emergency cesarean section and estimated the percent of emergency cesarean sections that would be obtained from a survey, given the observed prevalence, sensitivity, and specificity from this study. Hospital data were matched with exit interviews for 659 women delivered via cesarean section for Ghana and 1,531 for the Dominican Republic. In Ghana and the Dominican Republic, sensitivity and specificity for emergency cesarean section defined by decision time were 79% and 82%, and 50% and 80%, respectively. The validity of emergency cesarean defined by operation time showed less favorable results than decision time in Ghana and slightly more favorable results in the Dominican Republic. CONCLUSIONS: Questions used in this study to identify emergency cesarean section are promising

Rayleigh wave group-velocity across the Dominican Republic and Puerto Rico from ambient noise tomography

The eastern North America-Caribbean (NA-CAR) plate boundary near the islands of Hispaniola (which is comprised of the Dominican Republic and Haiti) and Puerto Rico is a complex transition zone in which strain is accommodated by two transform fault systems and oblique subduction. In 2013, scientists from Baylor University, the Autonomous University of Santo Domingo, and the Puerto Rico Seismic Network deployed 16 broadband stations on the Dominican Republic to expand the local permanent network. The goal of the Greater Antilles Seismic Program (GrASP) is to combine its data with that from permanent networks in Puerto Rico, Haiti, Cuba, the Cayman Islands, and Jamaica to develop a better understanding of the crust and upper mantle structure in the Northeastern Caribbean (Greater Antilles). One important goal of GrASP is to develop robust velocity models that can be used to improve earthquake location and seismic hazard efforts. In this study, we focus on obtaining Rayleigh wave group velocity maps from ambient noise tomography. By cross-correlating ambient seismic noise recorded at 53 stations between 2010 to present, we obtain Green's functions between 1165 pairs of stations. From these, we obtain dispersion curves by the application of FTAN methods with phase-matched filtering. Selection criteria depend on the signal-to-noise ratio and seasonal variability, with further filtering done by rejecting velocities incompatible with maps produced from overdamped tomographic inversions. Preliminary dispersion maps show strong correlations with large-scale geological and tectonic features for periods between 5 - 20 s, such as the Cordillera Central in both the Dominican Republic and Puerto Rico, the Mona Passage, and the NA-CAR subduction zone. Ongoing efforts focus on including shorter periods in Puerto Rico as its denser station distribution could allow us to retrieve higher resolution group velocity maps.

Ortega, M M

1974-01-01

This work has 3 objectives: to clarify the concept of population policy, to examine different theoretical approaches to the analysis of a national population policy, and to describe the origin, development, and present characteristics of the population policy of the Dominican Republic. The concept of population policy is often confused with the related concepts of responsible parenthood, family planning, and birth or population control. Population policy may be defined as a coherent group of declarations, decisions, and actions following a rational strategy which, as part of a national development plan, is formulated and implemented by the state and additional social institutions in accordance with national needs. Its final goal is the protection and development of human resources through influencing population characteristics. Although recent attempts to apply the methods of political analysis to the area of population policy all suffer from limitations, 4 frameworks which respectively look at the 3 levels of population policy (the philosophic-ideologic, the scientific, and the practical); at the division of population policy into declarations, decisions, programs, and results; at criteria for evaluating the probability of success of a population policy; and at the stages of development of population policies in dependent countries can be of assistance in understanding and evaluating the population policy of the Dominican Republic. Until 1961, the end of the Trujillo era, a pronatalist attitude predominated in the Dominican Republic, prompted in part by fears of an aggressive and densely populated Haiti sharing the same island. From 1962-66, a gradual change in attitudes began in the private sector as various groups began quiet efforts at family planning and the Dominican Association for Family Welfare was formed and became an affiliate of the International Planned Parenthood Federation. During this stage the government remained neutral or offered quiet support

Definitive surgical interventions for Dominican children with congenital heart disease, like those of other low- and middle-income countries, have been historically limited. We undertook review of a case series focusing on the surgical correction of complex forms of tetralogy of Fallot at a single center, CEDIMAT Centro Cardiovascular, in the Dominican Republic, over a 30-month period. According to our criteria, 43 cases were determined to be complex tetralogy of Fallot repairs from the two-year period. Besides tetralogy of Fallot, the cohort had an additional 55 anatomic anomalies that had to be addressed at the time of surgery. Median age at the time of surgery was notably 30 months, and an average of 42 months elapsed from the time of diagnosis to the time of surgery for this group. Only 33% of the cases reviewed had no hypercyanotic crises before repair. Median time to extubation for this group of patients was one day, with a three-day median length of stay in the intensive care setting. Our study importantly captures the present experience of a surgical congenital heart program that has recently transitioned from a traditional "mission model" to a now self-sustaining local practice. Both the number and the complexity of the lesions corrected in this caseload represent an advance from the level of care previously provided to children in the Dominican Republic.

This article is a report of the process and results of a feasibility pilot study to improve the quality of maternity care in a sample of 31 women and their newborns delivering in a public, tertiary hospital in the Dominican Republic. The pilot study was the first "action step" taken as a result of a formative, community-based participatory research (CBPR) study conducted between 2008 and 2010 by an interdisciplinary, international partnership of U.S. academic researchers, Dominican medical/nursing personnel, and Dominican community health workers. Health personnel and community health workers separately identified indicators most important to measure quality of antepartum maternity care: laboratory and diagnostic studies and respectful, interpersonal communication. At the midpoint and the completion of data collection, the CBPR team evaluated the change in quality indicators to assess improvement in care. The pilot study supports the idea that joint engagement of community health workers, health personnel, and academic researchers with data creation and patient monitoring is motivating for all to continue to improve services in the cultural context of the Dominican Republic. © The Author(s) 2014.

Recent studies in African contexts have revealed a strong association between spirit possession and severe trauma, with inclusion into a possession cult serving at times a therapeutic function. Research on spirit possession in the Dominican Republic has so far not included quantitative studies of trauma and dissociation. This study evaluated demographic variables, somatoform dissociative symptoms, and potentially traumatizing events in the Dominican Republic with a group of Vodou practitioners that either do or do not experience spirit possession. Inter-group comparisons revealed that in contrast to non-possessed participants (n = 38), those experiencing spirit possession (n = 47) reported greater somatoform dissociation, more problems with sleep, and previous exposure to mortal danger such as assaults, accidents, or diseases. The two groups did not differ significantly in other types of trauma. The best predictor variable for group classification was somatoform dissociation, although those items could also reflect the experience of followers during a possession episode. A factor analysis across variables resulted in three factors: having to take responsibility early on in life and taking on a professional spiritual role; traumatic events and pain; and distress/dissociation. In comparison with the non-possessed individuals, the possessed ones did not seem to overall have a remarkably more severe story of trauma and seemed to derive economic gains from possession practice.

Because human immunodeficiency virus (HIV)-infected patients receive prophylaxis with oxidative drugs, those with glucose-6-phosphate dehydrogenase (G6PD) deficiency may experience hemolysis. However, G6PD deficiency has not been studied in the Dominican Republic, where many individuals have African ancestry. Our objective was to determine the prevalence of G6PD deficiency in Dominican HIV-infected patients and to attempt to develop a cost-effective algorithm for identifying such individuals. To this end, histories, chart reviews, and G6PD testing were performed for 238 consecutive HIV-infected adult clinic patients. The overall prevalence of G6PD deficiency (8.8%) was similar in males (9.3%) and females (8.5%), and higher in Haitians (18%) than Dominicans (6.4%; P = 0.01). By logistic regression, three clinical variables predicted G6PD status: maternal country of birth (P = 0.01) and a history of hemolysis (P = 0.01) or severe anemia (P = 0.03). Using these criteria, an algorithm was developed, in which a patient subset was identified that would benefit most from G6PD screening, yielding a sensitivity of 94.7% and a specificity of 97.2%, increasing the pretest probability (8.8–15.1%), and halving the number of patients needing testing. This algorithm may provide a cost-effective strategy for improving care in resource-limited settings. PMID:26240158

The genus Diplosmittia was erected by Sæther (1981) based on Diplosmittia harrisoni from St. Lucia and St. Vincent in the British West Indies. Prior to the present study the genus comprised nine species, all except D. carinata Sæther were known only from Neotropical Region (Ashe & O'Connor, 2012). During sampling in the surroundings of a highly organic polluted river, in the National Botanical Garden in Santo Domingo, Dominican Republic, the present second author collected several imagines of Diplosmittia that did not fit any taxon treated in the recent review of the genus (Pinho et al. 2009). In the present paper, the male of this new species is described and illustrated.

To describe the most recent outbreak of diphtheria in the Dominican Republic and the disease's occurrence and vaccination coverage in 2004-2013. Clinical data of diphtheria cases that occurred in 2004 and that met the study's case definition were reviewed along with socioeconomic and epidemiological information from the cases' families. Univariate and multivariate analyses were performed to assess risk factors for fatal diphtheria. Routine surveillance and vaccination coverage data are presented. From January 2004-April 2005, a total of 145 diphtheria cases were reported; 80 (66%) of the 122 cases reported in 2004 met the case definition; 26 were fatal (case-fatality rate: 32.5%). Incidence was highest in the group 1-4 years of age at 5.3 per 100 000; 62.5% were male. Of the 80 cases, 61 (76%) where hospitalized in Hospital A, 17 in Hospital B, and 2 in two other hospitals. Earlier onset (first half of 2004), birth order, and tracheotomy were associated with fatal diphtheria (P diphtheria incidence was 4.91 cases/1 million people in 2000-2003, climbed to 8.8 cases per million in 2004-2005, and dropped to 0.38 in 2006-2014; no diphtheria cases have been reported since 2011. DTP3 vaccination coverage ranged from 72%-81% in 2000-2004 and from 81%-89% in 2005-2013. The 2004-2005 diphtheria outbreak in the Dominican Republic resulted in important and avoidable morbidity and mortality. Annual cases declined and no cases have been reported in recent years. Maintaining high vaccination coverage and diligent surveillance are crucial to preventing diphtheria outbreaks and controlling the disease.

Padilla, Mark B.; Guilamo-Ramos, Vincent; Godbole, Ramona

2012-01-01

The Dominican Republic has high rates of HIV infection and alcohol consumption. Unfortunately, little research has been focused on the broader sources of the synergy between these two health outcomes. We draw on syndemic theory to argue that alcohol consumption and sexual risk behavior are best analyzed within the context of culture and economy in Caribbean tourism spaces, which produce a synergy between apparently independent outcomes. We sampled 32 men and women working in the tourism industry at alcohol-serving establishments in Sosúa, Dominican Republic. Interviewees described alcohol consumption as an implicit requirement of tourism work, tourism industry business practices that foster alcohol consumption, and an intertwining relationship between alcohol and sexual commerce. The need to establish relationships with tourists, combined with the overconsumption of alcohol, contributed to a perceived loss of sexual control, which participants felt could impede condom use. Interventions should incorporate knowledge of the social context of tourism areas to mitigate the contextual factors that contribute to HIV infection and alcohol consumption among locals.

Full Text Available The possible impacts of the level of formal education on different aspects of disaster management, prevention, alarm, emergency, or postdisaster activities, were studied in a comparative perspective for three countries with a comparable exposure to hurricane hazards but different capacities for preventing harm. The study focused on the role of formal education in reducing vulnerability operating through a long-term learning process and put particular emphasis on the education of women. The comparative statistical analysis of the three countries was complemented through qualitative studies in Cuba and the Dominican Republic collected in 2010-2011. We also analyzed to what degree targeted efforts to reduce vulnerability were interconnected with other policy domains, including education and science, health, national defense, regional development, and cultural factors. We found that better education in the population had clear short-term effects on reducing vulnerability through awareness about crucial information, faster and more efficient responses to alerts, and better postdisaster recuperation. However, there were also important longer term effects of educational efforts to reduce social vulnerability through the empowerment of women, its effect on the quality of institutions and social networks for mutual assistance creating a general culture of safety and preparedness. Not surprisingly, on all three accounts Cuba clearly did the best; whereas Haiti was worst, and the Dominican Republic took an intermediate position.

2009-05-01

Full Text Available Abstract Background Phlebotomine sandflies are the vectors of etiological agents of leishmaniases in several areas of the world. In the Neotropical Region, the biodiversity of these insects is more than other regions, probably due the long evolutionary period of this group. Miocene amber from Dominican Republic, currently, has a record of 14 extinct species of Phlebotomine sandflies. Results This paper describes a new fossil species of phlebotomine sandfly from amber found in Dominican Republic. This new species is based on morphological characters of a male such as 5° palpomere longer than 3° + 4°, three well-developed spines in the gonostyle, lateral lobe longer than gonocoxite and permit inclusion of the new species in the genus Pintomyia, series serrana. The paramere, with a curvature in the ventral margin, of the middle of the structure, separates the new species from the others fossils or extant species. Conclusion The new species described in the present study named Pintomyia dissimilis nov. sp. is well differenciated from all known species in this genus.

Hardy, E E; Reyes, Q; Gomez, F; Portes-Carrasco, R; Faúndes, A

1983-11-01

The basis for this report is home interviews of users of the contraceptive vaginal ring and the pill from urban and rural clinics in 2 provinces in the Dominican Republic and clinics from 2 towns and a large city in Brazil. Dominican ring users were significantly more likely to be older than pill users, to have more schooling, and have partners with more education. 6% were illiterate and 75% had only elementary education. 1/10 of the ring users reported having had problems with insertion of the ring and 1/5 had problems removing it. It may be worthwhile to try a narrower, more flexible model that may be easier to insert and remove. 1 out of every 6 users reported vaginal odor, 1 out of 8 reported having felt the ring move in their vagina, and 1/3 were aware of the ring at some time. About 1/2 the women in each country said the ring had changed color during use, and about 1/2 of those who reported the change did not like it. It became light gray and looked dirty. Correction may improve acceptance. 10% reported having expelled the ring. Twice as many ring users reported having menstrual problems. Ring and pill users both reported headaches, vaginal discharge, menstrual pain, and increased libido. A large proportion of ring and pill users experienced decreased duration and amount of menstrual bleeding, which was seen more as a beneficial than a negative effect. The same can be said for weight gain, which was "linked" by 89% of the women in the Dominican Republic. 64% of ring users and 67% of pill users described thier respective method as good or very good. Detailed instructions should accompany the final model. They should say that it is alright for the ring to be any place within tha vagina for it to be effective.

Horizontal accountability and presidential dominance: a difficult combination. The case of the Dominican Republic, 1967-2009

Directory of Open Access Journals (Sweden)

Leiv MARSTEINTREDET

2011-03-01

Full Text Available This article studies horizontal accountability in the Dominican Republic. First it analyses the rules regulating the system of checks and balances. Although important, institutional rules cannot explain the variation in the levels of accountability across time found in the Dominican case. Therefore, the article focuses on the execution of national budgets and the financial situation of the accountability institutions. The article suggests using an index of budgetary disproportionality based on a comparison of the congressionally approved budget and the executed budget to measure the level of horizontal accountability. A multivariate time-series regression analysis shows that budgetary disproportionality increases with presidential dominance. The article concludes that for the period 1967-2009, it is presidential behaviour more than any other factor that has prevented an effective system of checks and balances. Therefore the case confirms O’Donnell’s hypothesis of Delegative Democracies.

2016-01-01

Although research demonstrates the public health burden of prostate cancer among men in the Caribbean, relatively little is known about the factors that underlie the low levels of testing for the disease among this population. Study Design. A cross-sectional study of prostate cancer testing behaviours among men aged 40-60 years in Dominican Republic using the Demographic and Health Survey (2013). Methods. We use hierarchical binary logit regression models and average treatment effects combined with propensity score matching to explore the determinants of prostate screening as well as the average effect of health insurance coverage on screening. The use of hierarchical binary logit regression enabled us to control for the effect of unobserved heterogeneity at the cluster level that may affect prostate cancer testing behaviours. Results. Screening varied significantly with health insurance coverage, knowledge of cholesterol level, education, and wealth. Insured men were more likely to test for prostate cancer (OR=1.65, P=0.01) compared to the uninsured. Conclusions. The expansion and restructuring of Dominican Republic universal health insurance scheme to ensure equity in access may improve health access that would potentially impact positively on prostate cancer screening among men.

1998-09-01

This study summarizes results from six data collection instruments administered to tourists, hotel workers, and commercial sex workers (CSWs) in the Dominican Republic (D.R.). The objective of this study was to assess: 1. how HIV/AIDS may affect tourism; 2. how tourists are likely to react to prevention campaigns; and 3. how tourism may affect the spread of HIV/AIDS. It was found that an overwhelming proportion of tourists did not consider the prevalence of HIV to be a factor when making their travel plans, and that most did not consider themselves at greater risk of becoming infected while on holiday than when they were at home. This study determined that the spread of HIV/AIDS was unlikely to affect the demand for tourism services in the D.R. The study also found that most tourists would respond positively to an HIV/AIDS prevention campaign and would not be discouraged from visiting the D.R. because of such campaigns. Those most receptive to prevention efforts were also those who felt they were at highest risk, according to study data. Finally, it was determined that while most tourists probably do not engage in high risk activities, there were some male and female tourists who do engage in sexual encounters with multiple Dominican CSWs and hotel employees. These encounters represent a risk to the health and economic development of the D.R., as well as to tourists and their other sexual partners. Based on these findings, it is recommended that in order to minimize the potential social and economic impact of HIV/AIDS in the D.R., prevention messages need to reach a number of groups which have not yet been adequately targeted. These groups include tourists, with a special emphasis on 'sex tourists', and hotel employees, with a special emphasis on entertainment staff.

Follow-up measles campaign in the Dominican Republic.

Science.gov (United States)

1998-12-01

The Dominican Republic conducted a national follow-up measles vaccination campaign 6 weeks after sustaining heavy damage from Hurricane Georges, on November 6-12, targeting 830,517 children aged 9 months to 5 years in 29 provinces and the capital city. This campaign was the first mass vaccination effort in the country, following the beginning of the decentralized delivery of health services. Priority was given to vaccinating against diphtheria, whooping cough, and tetanus, especially in refugee camps. More than 500,000 vaccines were given to different age groups, with almost 100,000 of those immunized under 5 years old. Children aged 9 months to 5 years were targeted for immunization regardless of their vaccination status. At the same time, children aged 2 months through 2 years were immunized against poliomyelitis. Vaccination activities were continued until the entire target population was reached and no important side effects have thus far been reported. The government of Mexico donated 300,000 doses of measles vaccine, while other vaccines for the campaign were acquired through the PAHO Revolving Fund for Vaccine Procurement. The decentralized implementation of this campaign allowed the population to actively participate and the resulting high vaccination coverage rates.

INTRODUCTION Health care workers have an increased risk of infection due to occupational Mycobacterium tuberculosis exposure, including multidrug-resistant strains. Health care workers' risk of developing tuberculosis is greater than that of the general population, whether in low-, intermediate- or high-incidence countries. Adherence to infection control measures (administrative controls, environmental controls, and personal respiratory protection) is essential to reduce risk of disease transmission between suspected tuberculosis patients and health care workers, but for different reasons, both objective and subjective, adherence is low. Identifying the causes of low adherence is a prerequisite to effective programming to reduce risk. OBJECTIVE Identify perceived barriers to adherence to tuberculosis infection control measures among health care workers in the Dominican Republic. METHODS During August 2014, a qualitative study was conducted in two tertiary-level hospitals in different regions of the Dominican Republic. A semi-structured interview guide of nine questions was developed, based on the scientific literature and with consensus of clinical experts. Nine semi-structured interviews were conducted with a purposive sample of seven physicians (five men, two women) and two baccalaureate nurses (both women) working in the emergency medicine, internal medicine or nursing departments of those institutions. Question topics included clinical experience of M. tuberculosis infection and disease; knowledge of disease transmission and preventive practices; clinical management strategies; and perceptions of effectiveness of directly observed treatment, short-course, and disease coping strategies. RESULTS Perceived barriers were described as: 1) sense of invincibility of health care workers; 2) personal beliefs of health care workers related to direct patient communication; 3) low provider-to-patient ratios in hospitals; 4) absence of tuberculosis isolation units for

Fifty-one atopic asthmatic and/or allergic rhinitic children and 23 nonatopic control from Santo Domingo, the Dominican Republic, were skin tested with an extract mix of three cockroach species (Blattella germanica, Blatta orientalis, and Periplaneta americana). Sixteen percent of the atopics and none of the nonatopics demonstrated positive immediate skin reactions to the cockroach mix (chi 2 = 4.05, p = 0.04). Hypersensitivity was correlated with the quality of the homes; 22% (8/36) of the atopics who lived in a concrete home were skin test positive to the cockroach mix, while none (0/15) of the atopics who lived in a wood home were skin test positive (chi 2 = 4.86, p = 0.03). Although the incidence of cockroach allergy in this study is lower than that found elsewhere, these data support the notion that, in this tropical environment, sensitization to cockroaches is associated with housing quality.

Likewise, it analyzes, the possibilities that represent the means of technology of the information and communication; in addition, it develops an analysis on the role of ICT in the work rooms, in the same way that influences the teaching-learning processes and the possible technical difficulties that can be generated. From a quantitative study with a non-experimental-transverse exploratory type design. With a probabilistic sample of 100 teachers to whom a survey was applied. The results reveal data that need special attention, given the nature of the context in which the study is developed. In this sense, a high index of teachers recognizes ICT as a fundamental instrument of educational innovation and facilitators of learning; however, they admit that they do not have basic training for their implementation.

1998-01-01

Diet data from 20 Burrowing Owl (Athene cunicularia) nests were collected in southwestern Dominican Republic in 1976, 1982, and 1996. Invertebrates (53.3%) comprised the most numerous prey items (N = 396) delivered to nests by adult owls, but vertebrates (46.7%) were much better represented than in other studies of Burrowing Owl diet. Among vertebrates, birds (28.3% of all items) and reptiles (14.9%) were most important, whereas mammals (1.0%) and amphibians (2.5%) were less commonly delivered to nests. Vertebrates, however, comprised more than twice (69.2%) of the total biomass as invertebrates (30.8%), with birds (50.4%) and reptiles (12.8%) the most important of the vertebrate prey classes. A positive relationship was observed between bird species abundance and number of individuals taken as prey by Burrowing Owls.

Objectives To assess the safety, acceptability, and preliminary efficacy of a culturally-adapted disclosure intervention for perinatally HIV-infected combined antiretroviral therapy patients in Haiti and the Dominican Republic. Design A quasi-experimental trial was conducted comparing caregiver–youth pairs who completed the intervention [adapted Blasini disclosure model (aBDM)] to pairs who discontinued aBDM participation before disclosure. aBDM consists of five components: structured healthcare worker training; one-on one pre-disclosure intervention/education sessions for youth (describing pediatric chronic diseases including cancer, diabetes and HIV) and for caregivers (strengthening capacity for disclosure); a scheduled supportive disclosure session; and one-on-one postdisclosure support for caregivers and youth. Methods Caregivers of nondisclosed combined antiretroviral therapy patients aged 10.0–17.8 years were invited to participate. Data were collected by separate one-on-one face-to-face interviews of caregivers and youth by study staff and medical record review by pediatricians at enrollment and 3 months after disclosure or after intervention discontinuation. Results To date, 65 Dominican Republic and 27 Haiti caregiver–youth pairs have enrolled. At enrollment, only 46.4% of youth had viral suppression and 43.4% of caregivers had clinically significant depressive symptomatology. To date, two serious study-related adverse events have occurred. Seven of the 92 (7.6%, 6 in the Dominican Republic) enrolled pairs discontinued participation before disclosure and 39 had completed postdisclosure participation. Median plasma HIV-RNA concentration was lower in youth who completed aBDM than in youth who discontinued participation before aBDM disclosure (<40 versus 8673 copies/ml; P = 0.027). Completers expressed considerable satisfaction with aBDM. Conclusion Preliminary results suggest safety, acceptability, and possible effectiveness of the aBDM. PMID:26049543

Little is known about the mental health of female sex workers and women living with HIV/AIDS in the Dominican Republic, which impedes HIV prevention, testing, and treatment. This project estimates the prevalence of depression and identifies key contributing factors to this outcome in female sex workers, women living with HIV/AIDS, and a comparison group. Participants were female sex workers (N = 349), women living with HIV/AIDS (N = 213), and a comparison group of HIV-negative women who were not sex workers (N = 314) from the Dominican Republic. Participants completed questionnaires assessing demographic characteristics and depression. Female sex workers and women living with HIV/AIDS completed additional questionnaires ascertaining HIV or sex work-related internalized stigma. Depression was prevalent among female sex workers (70.2%), women living with HIV/AIDS (81.1%), and the comparison group (52.2%). Adjusted logistic regressions showed that internalized stigma was associated with depression for female sex workers (OR = 2.73; 95% CI = 1.95-3.84) and women living with HIV/AIDS (OR = 3.06; 95% CI = 1.86-5.05). Permanent income was associated with this outcome for female sex workers (OR = 0.08; 95% CI = 0.01-0.80) and the comparison group (OR = 0.04; 95% CI = 0.00-0.45).

Full Text Available Abstract Background Demographic ageing, and the health transition will soon lead to large increases in the number of dependent older people in low and middle income countries. Despite its importance, this topic has not previously been studied. Methods A cross sectional catchment area one-phase survey of health conditions, dependency, care arrangements and caregiver strain among 2011 people aged 65 years and over in Santo Domingo, Dominican Republic Results 7.1% of participants required much care and a further 4.7% required at least some care. The prevalence of dependency increased sharply with increasing age. Dependent older people were less likely than others to have a pension and much less likely to have paid work, but no more likely to benefit from financial support from their family. Needing much care was strongly associated with comorbidity between cognitive, psychological and physical health problems. However, dementia made the strongest independent contribution. Among those needing care, those with dementia stood out as being more disabled, as needing more care (particularly support with core activities of daily living, and as being more likely to have paid caregivers. Dementia caregivers experienced more strain than caregivers of those with other health conditions, an effect mediated by behavioural and psychological symptoms. Conclusion Dependency among older people is nearly as prevalent in Dominican Republic as in developed western settings. Non-communicable diseases, particularly dementia are the main contributing factors. Attention needs to be directed towards the development of age-appropriate healthcare, a long-term care policy, and mechanisms for ensuring the social protection of older persons.

This article presents the feasibility and acceptability of using mobile health technology by community health workers (CHWs) in San Juan Province, Dominican Republic, to improve identification of pregnancy complications and access to care for pregnant women. Although most women in the Dominican Republic receive four antenatal care visits, poor women and adolescents in remote areas are more likely to have only one initial prenatal visit to verify the pregnancy. This community-based research began when community leaders raised concern about the numbers of their mothers who died in childbirth annually; San Juan's maternal mortality rate is 144/100,000 compared to the Caribbean rate of 85/100,000. Eight CHWs in three communities were taught to provide third-trimester antenatal assessment, upload the data on a mobile phone application, send the data to the local physician who monitored data for "red flags," and call directly if a mother had an urgent problem. Fifty-two pregnant women enrolled, 38 were followed to delivery, 95 antenatal care postintake were provided, 2 urgent complications required CHW home management of mothers, and there were 0 deaths. Stakeholders endorsed acceptability of intervention. Preliminary data suggest CHWs using mobile health technology is feasible, linking underserved and formal health care systems with provision of primary care in mothers' homes.

Foster, Jennifer; Pullen, Sara

2016-01-01

Despite the logistical barriers of asynchronous academic calendars, university students in nursing and physical therapy in one academic health centre piloted an international, interprofessional, service learning project in the Dominican Republic. Although the nursing students and physical therapy students were not able to be in-country at the same time, they provided care to a common caseload of traumatic injury patients and those with chronic, debilitating conditions. Interprofessional communication occurred with the development of SBAR (Situation, Background, Assessment, Recommendation) reports from the Team Training curriculum of the Agency for Healthcare Research and Quality. Students learned the depth of physical therapy and the breadth of nursing. The pilot led to a more refined design to pair nursing and PT students, requiring them to communicate via mobile phone regarding results of examinations, and suggestions for follow-up by the nursing students, to ensure continuity of care and a more comprehensive approach to services.

Dominican NGOs move from competition to collaboration.

In 1992, the seven nongovernmental organizations (NGO) working to prevent HIV/AIDS in the Dominican Republic received most of their funding and technical assistance from the US Agency for International Development (USAID). In September 1992, however, USAID's AIDSTECH project asked the AIDS Control and Prevention (AIDSCAP) Project to prepare the NGOs for the time when USAID would no longer be their main source of support. To that end, AIDSCAP worked with NGO staff to assess their technical, managerial, and administrative needs, and identified a lack of administrative and managerial experience among many NGO staff. AIDSCAP therefore developed an institutional strengthening plan, including a series of capacity building workshops, in 1993. Many NGOs, however, foreseeing the impending need to compete with other NGOs for limited funds, were not interested in sharing ideas and working together. This article describes how Coordinadora de Animacion Socio-Cultural (CASCO) and the Instituto Dominicano de Desarrollo Integral (IDDI) competed in the context of uncertainty over continued donor funding, but now meet regularly to coordinate HIV/AIDS prevention projects for youth in the Dominican Republic.

We compared suicide attempts, depressed mood, and drug use of 1,710 Dominican public high school students in New York City (NYC) and 9,573 in the Dominican Republic (DR) in 2009. Compared to DR Dominicans, NYC Dominicans were more likely to have reported lifetime marijuana use (27.6% vs. 1.5%), lifetime inhalant use (11.0% vs. 7.6%), lifetime other drug use (9.9% vs. 3.0%), depressed mood (31.3% vs. 27.2%), and suicide attempt (13.8% vs. 8.8%). The results of this study supported the hypothesis that substantial increases in illicit drug use, especially cocaine, heroin, ecstasy, and methamphetamines, among NYC Dominican youth account for their increased risk for suicide attempts compared to their DR Dominican counterparts. It also identified suicide attempts as a public health problem among NYC Dominicans, the largest NYC Latino immigrant population. © 2015 The American Association of Suicidology.

Introduction Not only do transgender female sex workers have some of the highest rates of sexually transmitted infections (STI), human immunodeficiency virus (HIV), and experienced stigma, they also have higher likelihood of early sexual debut and some of the lowest levels of educational attainment compared to other stigmatized populations. Some of the most common interventions designed to reduce transmission of HIV and STIs seek to educate high-risk groups on sexual health and encourage condom use across all partner types; however, reaching stigmatized populations, particularly those in resource-limited settings, is particularly challenging. Considering the importance of condom use in stopping the spread of HIV, the aim of this study was two-fold; first to characterize this hard-to-reach population of transgender female sex workers in the Dominican Republic, and second, to assess associations between their HIV knowledge, experienced stigma, and condom use across three partner types. Methods We analyzed self-reported data from the Questionnaire for Transgender Sex Workers (N = 78). Respondents were interviewed at their workplaces. Univariate and bivariate analyses were employed. Fisher Chi-square tests assessed differences in HIV knowledge and experienced stigma by condom use across partner types. Results HIV knowledge was alarmingly low, condom use varied across partner type, and the respondents in our sample had high levels of experienced stigma. Average age of first sexual experience was 13.12 years with a youngest age reported of 7. Dominican Republic statutory rape laws indicate 18 years is the age of consent; thus, many of these transgender women’s first sexual encounters would be considered forcible (rape) and constitute a prosecutable crime. On average, respondents reported 8.45 sexual partners in the prior month, with a maximum of 49 partners. Approximately two thirds of respondents used a condom the last time they had sex with a regular partner. This

Culture and drug susceptibility testing among previously treated tuberculosis patients in the Dominican Republic, 2014

Directory of Open Access Journals (Sweden)

Katia J. Romero Mercado

Full Text Available ABSTRACT Multidrug-resistant tuberculosis (MDR-TB is a major public health concern that threatens global progress toward effective TB control. The risk of MDR-TB is increased in patients who have received previous TB treatment. This article describes the performance of culture and drug susceptibility testing (DST in patients registered as previously treated TB patients in the Dominican Republic in 2014, based on operational research that followed a retrospective cohort design and used routine program data. Under the current system of TB culturing and DST, the majority of patients with previously treated TB do not undergo DST, and those who do often experience considerable delay in obtaining their results. The lack of DST and delay in receiving DST results leads to underestimation of the number of MDR-TB cases and hinders the timely initiation of MDR-TB treatment.

Characterizing HIV epidemiology in stable couples in Cambodia, the Dominican Republic, Haiti, and India.

Chemaitelly, H; Abu-Raddad, L J

2016-01-01

Using a set of statistical methods and HIV mathematical models applied on nationally representative Demographic and Health Survey data, we characterized HIV serodiscordancy patterns and HIV transmission dynamics in stable couples (SCs) in four countries: Cambodia, the Dominican Republic, Haiti, and India. The majority of SCs affected by HIV were serodiscordant, and about a third of HIV-infected persons had uninfected partners. Overall, nearly two-thirds of HIV infections occurred in individuals in SCs, but only about half of these infections were due to transmissions within serodiscordant couples. The majority of HIV incidence in the population occurred through extra-partner encounters in SCs. There is similarity in HIV epidemiology in SCs between these countries and countries in sub-Saharan Africa, despite the difference in scale of epidemics. It appears that HIV epidemiology in SCs may share similar patterns globally, possibly because it is a natural 'spillover' effect of HIV dynamics in high-risk populations.

Full Text Available Abstract Background HIV/AIDS treatment programs are currently being mounted in many developing nations that include palliative care services. While measures of palliative care have been developed and validated for resource rich settings, very little work exists to support an understanding of measurement for Africa, Latin America or Asia. Methods This study investigates the construct validity of measures of reported pain, pain control, symptoms and symptom control in areas with high HIV-infected prevalence in Dominican Republic and Cambodia Measures were adapted from the POS (Palliative Outcome Scale. Households were selected through purposive sampling from networks of people living with HIV/AIDS. Consistencies in patterns in the data were tested used Chi Square and Mantel Haenszel tests. Results The sample persons who reported chronic illness were much more likely to report pain and symptoms compared to those not chronically ill. When controlling for the degrees of pain, pain control did not differ between the chronically ill and non-chronically ill using a Mantel Haenszel test in both countries. Similar results were found for reported symptoms and symptom control for the Dominican Republic. These findings broadly support the construct validity of an adapted version of the POS in these two less developed countries. Conclusion The results of the study suggest that the selected measures can usefully be incorporated into population-based surveys and evaluation tools needed to monitor palliative care and used in settings with high HIV/AIDS prevalence.

Garcia, A.; Semken, S. C.; Brandt, E.

2017-12-01

Ethnogeology is the scientific study of human relationships with and knowledge of the Earth system, and is typically investigated within the context of a specific culture. Many indigenous and local systems of environmental and place knowledge incorporate empirical observations and culturally framed interpretations of geological features and processes. Ethnogeological interpretations may differ from those of conventional mainstream geoscience, but they are validated by their direct relevance to long-term cultural and environmental resilience and sustainability, typically in challenging environments. Ethnogeologic findings can enrich geoscientific knowledge bases for further research, and inform place-based geoscience education that has been shown to engage and enrich students from diverse underrepresented minority backgrounds. Ethnogeological research blends methods from field geology with methods from field ethnography: such as participant observation, free listing, participatory mapping, and cultural consensus analysis among other methods from rapid participatory assessment. We report here on an ongoing field study in Puerto Rico (PR) and the Dominican Republic (DR) on ethnogeological knowledge of karst topography, geology, and hydrogeology among local cultural indigenous communities such as the Boricua jíbaro and the Dominican campesino. Applied focused ethnographic fieldwork results suggest a good fit for the cultural consensus model about geological processes among culturally expert consultants in DR (4.604) and PR (4.669), as well as competence average with values of 0.552 and 0.628 respectively. This suggests the existence of a regional cultural model for the domain of karst that is shared between PR and DR populations that reside in or near karst terrain. Additional data in support of the cultural model include stories, analogies, and family history using participant observation, and participatory mapping.

Adolescent pregnancy is a major health concern among Dominicans in the U.S. and in the Dominican Republic (DR). Twenty three percent of adolescents age 15-19 have experienced pregnancy and this trend is rising. The purpose of this study was to explore and compare social support, self-esteem and pregnancy between Dominican adolescents in the DR with those who have immigrated to the U.S. This study used an exploratory, descriptive design including study samples from both the U.S. and DR. Findings showed that young women with stronger social support and higher self esteem experienced lower pregnancy rates in both the DR and U.S. Neither self esteem nor social support was found to be predictors of pregnancy. Important findings from this study will inform the development of interventions aimed at preventing pregnancy in adolescents. Copyright © 2014 Elsevier Inc. All rights reserved.

Gendered dynamics in heterosexual relationships compromise women's self-efficacy and increase their vulnerability to acquiring HIV. This study examines the impact of socioeconomic determinants, media exposure, and sexual expectations on sexual behaviors of men and women in the Dominican Republic (DR). We analyzed cross-sectional data from 51,018 adults in the Dominican Republic age 15 to 45 years collected by the Demographics and Health Survey (DHS) in 2007. Measures included demographic and socioeconomic indicators, social exposures, sexual expectations and sexual behaviors. Logistic regression models explored gender differences in condom use. Study findings indicated that women were less likely to use a condom at last intercourse than men (odds ratio [OR] = 0.29; 95 % CI = 0.27, 0.31). Among men, secondary (OR = 1.43; 95 % CI = 1.16, 1.76) and higher education (OR = 1.58; 95 % CI = 1.25, 2.00), being in the richest quintile (OR = 1.25; 95 % CI = 1.07, 1.47), and living in a female-headed household (OR = 1.13; 95 % CI 1.03, 1.23) increased the likelihood of condom use. Compared to never married men, currently and formerly married men were less likely to use condoms (OR = 0.03; 95 % CI = 0.03, 0.04 and OR = 0.67; 95 % CI = 0.60, 0.75, respectively). The odds of condom use increased for young women 15-19 years old in comparison with women age 30-34 years, but decreased as they grew older. For women, being in the richer quintile (OR = 1.28; 95 % CI = 1.06, 1.54), living in a female-headed household (OR = 1.26; 1.12, 1.41), and having good access to media (OR = 1.24; 95 % CI = 1.12, 1.42) increased the likelihood of condom use. Being currently married or formerly married and living in rural areas decreased such likelihood among women. Study findings provide evidence that, in the DHS, socioeconomic and cultural differences between men and women affects condom use. Efforts to reduce HIV transmission

Effective treatment and management of human immunodeficiency virus (HIV) depend on patients' ability to locate, comprehend, and apply health information. This study's purpose was to identify characteristics associated with these skills among HIV positive adults in the Dominican Republic. An information behavior survey was administered to 107 participants then three logistic regressions were conducted to identify characteristics associated with information seeking, processing, and use. Never having cared for someone who was sick was significantly associated with less information seeking, processing, and use. Males were more likely to be active information seekers and those who had attended the clinic for six or fewer years were less likely to actively seek information. Younger individuals had increased odds of higher information processing and those without comorbidities had increased odds of more information use. Results may inform researchers, organizations, and providers about how patients interact with health information in limited resource settings.

Female sex workers (FSWs) living with HIV are a vulnerable population for multiple health concerns and have been vastly understudied in public health literature. This study analyzes factors related to pregnancy among 268 FSWs living with HIV in the Dominican Republic. Results indicate that 34 % of participants had been pregnant since HIV diagnosis. Multivariate analysis revealed significant associations between pregnancy after HIV diagnosis and ART interruption (AOR 2.41; 95 % CI 1.19, 4.94), knowledge of mother-to-child transmission (AOR 2.12; 95 % CI 0.99, 4.55), serostatus disclosure to a sex partner (AOR 2.46; 95 % CI 1.31, 4.62), older age (AOR 0.91; 95 % CI 0.87, 0.95) and a more negative perception of their health provider (AOR 0.56; 95 % CI 0.34, 0.93). Results indicate noteworthy associations between having been pregnant and the health provider experience and ART interruption, indicating a significant need for further research on this population to ensure both maternal and child health.

To conduct formative research on the landscape of tobacco use to guide survey and subsequent intervention development in the Dominican Republic (DR). Rapid Assessment Procedures, systematic qualitative methods (participant-observations, in-depth interviewing, focus groups) using bilingual mixed age and gendered teams from the United States and DR. Over 160 adults (men and women), ages 18 to 90 years, current, former and never smokers, community members and leaders from six underserved, economically disadvantaged DR communities. Key domains: tobacco use patterns and attitudes; factors affecting smoking initiation, continuation, quitting; perceived risks/benefits/effects of smoking; and awareness/effects of advertising/regulations. Perceptions of prevalence varied widely. While "everybody" smokes, smokers or ex-smokers were sometimes difficult to find. Knowledge of health risks was limited to the newly mandated statement "Fumar es prejudicial para la salud" [Smoking is harmful to your health]. Smokers started due to parents, peers, learned lifestyle, fashion or as something to do. Smoking served as an escape, relaxation or diversion. Quit attempts relied on personal will, primarily for religious or medical reasons. Social smoking (custom or habit) (lifestyle choice rather than a vice or addiction. Out of respect, smokers selected where they smoked and around whom. Health care providers typically were reactive relative to tobacco cessation, focusing on individuals with smoking related conditions. Tobacco advertising was virtually ubiquitous. Anti-tobacco messages were effectively absent. Cultures of smoking and not smoking coexisted absent a culture of quitting. Systematic qualitative methods provided pertinent information about tobacco attitudes and use to guide subsequent project steps. Integrating qualitative then quantitative research can be replicated in similar countries that lack empirical data on the cultural dimensions of tobacco use.

Scleroderma is a rare disease with limited data in Latin America. Preliminary genetic studies suggest a strong African ascendance in the Dominican Republic, which could modulate the expression of the disease. The objective of this study is to describe the clinical and demographic characteristics of scleroderma in a series of 26 Dominican patients. Patients who fulfilled the EULAR/ACR criteria for scleroderma were selected from the Rheumatology Department of a tertiary health center; systemic sclerosis subtypes were defined according to the EULAR classification. Clinical and demographic information was obtained retrospectively from clinical records. Mean age at time of onset was 32.6±15 years; 68% of patients had 40 years of age or less. 73% of patients was feminine, with a female:male ratio of 2.7:1. The most affected systems were pulmonary and gastrointestinal; renal affection was scarce. Anti-Scl-70 antibodies were positive in 64% of patients, sometimes in coexistence with anti-centromere antibodies. The prevalence of systemic sclerosis is lower in the Dominican population than the reported elsewhere. The age of onset of the disease seems to be lower in the Dominican population than that reported in literature. A different pattern of autoantibodies is observed in this population.

Full Text Available The Dominican/Haitian border is signed by profound asymmetries and the predominance of a relation of uneven exchange in benefit of Dominican Republic. Transborder relations summary this contradictory relation, but at the same time constitute the only form of survival for more than half million of Haitians that inhabit the region. This article discusses the history of this relation and its present tendencies, including the formation of economic regions and urban binational systems. The weakness of regulatory public policies and the aggressive action of the market generate a very contradictory setting that could lead to conflicts by the use of shared natural resources, the exploitation of the Haitian labour force, and the agitation of nationalist positions.

The Caribbean region has one of the highest proportions of HIV in the general female population attributable to sex work. In 2008 (n = 1256) and 2012 (n = 1525) in the Dominican Republic, HIV biological and behavioral surveys were conducted among female sex workers (FSW) in four provinces using respondent driven sampling. Participants were ≥15 years who engaged in intercourse in exchange for money in the past 6 months and living/working in the study province. There were no statistically significant changes in HIV and other infections prevalence from 2008 to 2012, despite ongoing risky sexual practices. HIV testing and receiving results was low in all provinces. FSW in 2012 were more likely to receive HIV testing and results if they participated in HIV related information and education and had regular checkups at health centers. Further investigation is needed to understand barriers to HIV testing and access to prevention services.

A paleomagnetic and rock magnetic study was conducted in the northern Dominican Republic to detect vertical axis rotations in an active left-lateral, strike slip fault zone. 191 samples from 21 sites were collected from a variety of lithologies including limestones, conglomerates, calcarenites and marls that ranged in age from the Oligocene to the Holocene. The rock magnetic portion of the study focused on the identification of magnetic minerals using coercivity, and Curie temperature (c vs temperature) measurement, modeling of IRM acquisition curves, and thermal demagnetization of IRMs (Lowrie, 19901). In the paleomagnetic portion of the study characteristic remanences (ChRMs) were isolated using thermal demagnetization (19 steps up to 680ºC) and alternating field (AF) demagnetization (17 steps up to 100 mT). In most cases the characteristic remanence is carried by magnetite, with peak unblocking temperatures of 575ºC. This interpretation was supported by c vs. T results that yielded Curie temperatures of 580˚C. In only a few cases (7 samples) higher unblocking temperatures suggested hematite as the magnetic carrier. The modeling of IRM acquisition curves, that shows two coercivity components, further supports the presence of magnetite. 75% of the IRM is carried by the low-coercivity component (100-300 mT, magnetite). 25% of the IRM is carried by the high-coercivity component (1.2-1.6T) characteristic of hematite. The IRM acquisition data was collected from 24 samples (3-4 from each of the lithologies sampled). IRMs were acquired in fields from 4mT to 1T in 23 steps. The paleomagnetic results show a grouping by tectonic blocks with one group having westerly ChRM declinations (268˚-295˚) and a second group having northerly ChRM declinations (357˚-035˚). In most cases, inclinations are intermediate ( 35˚), in agreement with the 24˚-31˚ expected inclinations for Dominican Republic in the period Oligocene to Holocene. The rotation of the tectonic blocks, as

Characterize the capacity of public and private institutions in the Central American countries, the Dominican Republic, and the Mexican states of Chiapas and Quintana Roo to perform essential public health functions (EPHFs). An online survey of 83 organizations in Belize, Costa Rica, the Dominican Republic, El Salvador, Guatemala, Honduras, Nicaragua, Panama, and the Mexican states of Chiapas and Quintana Roo was conducted to learn about their capacity to perform each of the 11 EPHFs. The results were validated in a workshop with representatives of the ministries of health from the seven countries and the two participating Mexican states. High levels of performance capacity were found most often for EPHF 1 (monitoring, evaluation, and analysis of health status of the population), EPHF 2.1.1 (surveillance, research, and control of risks and threats to public health from infectious diseases), and EPHF 5 (policy development and health planning). The greatest weakness was found in EPHF 2.1.2 (surveillance, research, and monitoring of noninfectious diseases). Asymmetries in EPHF performance within each country mainly revealed weaknesses in the laboratory and public health research functions. In the countries and territories analyzed, there is a need to improve strategic performance in most of the EPHFs, as well as to strengthen infrastructure, upgrade equipment, and further develop human resources at both the strategic and the tactical levels. A regional approach should be used to take advantage of the different levels of capacity, with a view to greater strengthening and enhanced technical support and cooperation.

Passion Plays: The Dominican Diaspora in Waddys Jáquez’s P.A.R.G.O.

Full Text Available This article analyzes how the play P.A.R.G.O. (2001, written, directed, and performed by the Dominican Waddys Jáquez represents the contemporary experience of the Dominican diaspora. Jaquéz himself forms part of a new generation of diasporic artists who frequently return “home,” to the Dominican Republic, and who, unlike the previous generation of diasporic artists and writers, continue to find their most valuable audience there. This tendency towards an increasing interconnectivity between diaspora and homeland is represented and a/effectively reinforced in P.A.R.G.O. The play brings the experience of the diaspora close to home for the audience, not by compelling them to identify with the characters’ particular identities, but rather by placing center stage their ongoing negotiations and “making do” with personal and economic difficulties that define their lives both at home and abroad.

This paper focuses on a mixed-method approach to quantifying qualitative data from the results of an ongoing NIDA-funded ethnographic study entitled "Migration, Tourism, and the HIV/Drug-Use Syndemic in the Dominican Republic". This project represents the first large-scale mixed method study to identify social, structural, environmental, and demographic factors that may contribute to ecologies of health vulnerability within the Caribbean tourism zones. Our research has identified deportation history as a critical factor contributing to vulnerability to HIV, drugs, mental health problems, and other health conditions. Therefore, understanding the movements of our participants became a vital aspect of this research. This paper describes how we went about translating 37 interviews into visual geographic representations. These methods help develop possible strategies for confronting HIV/AIDS and problematic substance use by examining the ways that these epidemics are shaped by the realities of people's labor migration and the spaces they inhabit. Our methods for mapping this qualitative data contribute to the ongoing, broadening capabilities of using GIS in social science research. A key contribution of this work is its integration of different methodologies from various disciplines to help better understand complex social problems.

Full Text Available This paper presents a research project launched by the Ministry of Higher Education, Science and Technology of the Dominican Republic in 2011 with the aim of drawing up a formal and methodological basis that is used as a guideline to redefine the Bachelor’s Degree in Tourism. The main strategic lines of action derived from two essential requirements: the need to cater for a wider range of professional profiles and the need for curricular touristification. On the one hand, the focus was on the development of the graduates’ competences in all the cognitive areas involved in tourism to enable them to set up and manage tourist companies, products and destinations. This would generate innovative options of economic revitalization, decentralizing the current focus on the hospitality industry and incorporating new professional contexts with growth potential in the Dominican tourism sector. On the other hand, tourism-related subjects were reinforced and close cooperation with professionals on active service was highly recommended. Given the heterogeneity of current and potential local tourist destinations, the idiosyncrasy of each regional educational setting was taken into account to encourage entrepreneurship by empowering future managers of small and medium sized companies to make the most of their resources.

Poverty reduction interventions through cash transfers and microcredit have had mixed effects on mental health. In this quasi-experimental study, we evaluate the effect of a living wage intervention on depressive symptoms of apparel factory workers in the Dominican Republic. Two apparel factories in the Dominican Republic. The final sample consisted of 204 hourly wage workers from the intervention (99) and comparison (105) factories. In 2010, an apparel factory began a living wage intervention including a 350% wage increase and significant workplace improvements. The wage increase was plausibly exogenous because workers were not aware of the living wage when applying for jobs and expected to be paid the usual minimum wage. These individuals were compared with workers at a similar local factory paying minimum wage, 15-16 months postintervention. Workers' depressive symptoms were assessed using the Center for Epidemiologic Studies-Depression Scale (CES-D). Ordinary least squares and Poisson regressions were used to evaluate treatment effect of the intervention, adjusted for covariates. Intervention factory workers had fewer depressive symptoms than comparison factory workers (unadjusted mean CES-D scores: 10.6 ± 9.3 vs 14.7 ± 11.6, p = 0.007). These results were sustained when controlling for covariates (β = -5.4, 95% CI -8.5 to -2.3, p = 0.001). In adjusted analyses using the standard CES-D clinical cut-off of 16, workers at the intervention factory had a 47% reduced risk of clinically significant levels of depressive symptoms compared with workers at the comparison factory (23% vs 40%). Policymakers have long grappled with how best to improve mental health among populations in low-income and middle-income countries. We find that providing a living wage and workplace improvements to improve income and well-being in a disadvantaged population is associated with reduced depressive symptoms.

Energy production on islands is based, as on continents, on fossil fuels. In the Dominican Republic, the production has been insufficient, a recognized fact since 1897. In 1998, the opening to privatization of energy services was impelled by the Comisión para la Reforma de la Empresa Pública (CREP). Then the promulgation of the Ley General de Electricidad in July 2001 by decree #125 is a first step for renewable energy integration in the electric system. We present a historical approach to the energy problem using documents of 1897, 1946, 1989 and 2001(point 1). Then we present the components of energy production in the Dominican Republic by 2000 (point 2). The demand reached for that year 2000 MW, with only 1600 MW installed capacity. Some elements of the first institutional and legislative impulses to integrate renewable energy in the system are included (point 3). Finally, we underline the last 2013 crisis and show how only fossil energy allows to respond rapidly (point 4). In fact, renewable energies require a long term for planning and execution.

Earthquake effects are frequently quantified by the energy liberated at the source, and the degree of damage produced in urban areas. The damage of historic events such as the Mw=8.3, September 19, 1985 Mexico City Earthquake was dominated by the amplification of seismic waves due to local site conditions. The assessment of local site effects can be carried out with site response analyses in order to determine the properties of the subsoil such as the dominant period, and the Vs30. The evaluation of the aforementioned properties is through the analysis of ground motion. However, in locations with low seismicity, the most convenient method to assess the site effect is the analysis of ambient vibration measurements. The Spatial Auto Correlation method (SPAC) can be used to determine a Vs30 model from ambient vibration measurements using a triangular array of sensors. Refraction Microtremor (ReMi) considers the phase velocity of the Rayleigh waves can be separated of apparent velocities; the aim of the ReMI method is to obtain the Vs30 model. The HVSR technique or Nakamura's method has been adopted to obtain the resonant frequency of the site from the calculation of ratio between the Fourier amplitude spectra or PSD spectrum of the horizontal and vertical components of ambient vibration. The aim of this work is to compare the results using different techniques to assess local site conditions in the urban area of Santo Domingo, Dominican Republic. The data used was collected during the Pan-American Advance Studies Institute (PASI), Workshop held in Santo Domingo, Dominican Republic from July 14 to 25, 2013. The PASI was sponsored by IRIS Consortium, NSF and DOE. Results obtained using SPAC, and ReMi, show a comparable model of surface waves velocities. In addition to the above, the HVSR method is combined with the stiffness matrices method for layered soils to calculate a model of velocities and the predominant period on the site. As part of this work a comparison with

While the Caribbean has the second highest global human immunodeficiency virus (HIV) prevalence, insufficient attention has been paid to contributing factors of the region's elevated risk. Largely neglected is the potential role of drugs in shaping the Caribbean HIV/acquired immune deficiency syndrome epidemic. Caribbean studies have almost exclusively focused on drug transportation and seldom acknowledged local user economies and drug-related health and social welfare consequences. While tourism is consistently implicated within the Caribbean HIV epidemic, less is known about the intersection of drugs and tourism. Tourism areas represent distinct ecologies of risk often characterised by sex work, alcohol consumption and population mixing between lower and higher risk groups. Limited understanding of availability and usage of drugs in countries such as the Dominican Republic (DR), the Caribbean country with the greatest tourist rates, presents barriers to HIV prevention. This study addresses this gap by conducting in-depth interviews with 30 drug users in Sosúa, a major sex tourism destination of the DR. A two-step qualitative data analysis process was utilised and interview transcripts were systematically coded using a well-defined thematic codebook. Results suggest three themes: (1) local demand shifts drug routes to tourism areas, (2) drugs shape local economies and (3) drug use facilitates HIV risk behaviours in tourism areas.

Caribbean reefs changed profoundly in taxonomic composition, diversity, and dominance structure during late Pliocene and Pleistocene climatic change. These changes coincide with protracted climatic deterioration and cooling between 2.0 to 0.8 Ma, and the onset of high amplitude sea-level fluctuations ~400 ka. The Dominican Republic Drilling Project (DRDP) was initiated to determine how climate change and global high-amplitude sea level changes influenced depositional patterns in Pliocene to Recent reef systems of the Caribbean. A transect of 7 core borings (~700 m total depth) were collected along the southern coast of the DR. New age constraints based on U/Th geochronometry and radiogenic Sr isotopes, combined with depositional lithofacies, faunal indicators, and stable isotope profiles have allowed us to correlate between wells and define the internal anatomy and stratal geometry of the individual reef sigmoids and sigmoid sets. Faunal records suggest most extinction occurred prior to ~1 Ma. Following this extinction, fringing reef margins of the Caribbean display a characteristic zonation in which Acropora palmata dominates shallow high-energy reef crests and Acropora cervicornis calmer fore-reef slopes and backreef lagoons. The dominance of acroporids across this zonation has been attributed to growth rates 5-100 times faster than other corals.

Full Text Available This article explores forms of migrant families’ reorganization within a (new global economic crisis and the hardening of migration control in Europe; based on the cases of Dominican and Brazilian migration to Spain.Our goal is not to characterize the wholeness of strategies from these collectives, instead visualize its heterogeneity. Displacement of Dominican and Brazilian population to Spain shares the role of women as the first link of migration chains. In both cases women are the economic support of transnational families and they lead reunification's processes. Nevertheless, differences in the time spent in the destination country, migratory status, origin (rural-urban, level of education, class and labor insertion in destination country, affect differently, the planning and start up of migration projects, the organization of care and family reunification strategies. These findings question the predominant place granted to national origin in the study of international migration.

The embodiment of tourism among bisexually-behaving Dominican male sex workers.

Padilla, Mark B

2008-10-01

While theories of "structure" and social inequality have increasingly informed global health efforts for HIV prevention--with growing recognition of the linkages between large-scale political and economic factors in the distribution and impact of the HIV/AIDS epidemic--there is still little theorization of precisely how structural factors shape the very bodies and sexualities of specific populations and groups. In order to extend the theoretical understanding of these macro-micro linkages, this article examines how the growth of the tourism industry in the Dominican Republic has produced sexual practices and identities that reflect both the influence of large-scale structural processes and the resistant responses of local individuals. Drawing on social science theories of political economy, embodiment, and authenticity, I argue that an understanding of patterns of sexuality and HIV risk in the region requires analysis of how political-economic transformations related to tourism intersect with the individual experiences and practices of sexuality on the ground. The analysis draws on long-term ethnographic research with bisexually behaving male sex workers in two cities in the Dominican Republic, including participant observation, in-depth interviews, focus groups, and surveys. By examining the global and local values placed on these men's bodies and the ways sex workers use their bodies to broker tourists' pleasure, we may better understand how the large-scale structures of the tourism industry are linked to the specific meanings and practices of sexuality.

'Western Union daddies' and their quest for authenticity: an ethnographic study of the Dominican gay sex tourism industry.

2007-01-01

This article draws on ethnographic research among two categories of male sex workers in the Dominican Republic in order to describe the relationships between gay male tourists and the Dominican men they hire on their trips to the Caribbean. Drawing on both qualitative interview data and quantitative surveys, the discussion examines the usefulness of theories of 'authenticity,' as they have been applied in the analysis of tourist practices more generally, in accounting for the behaviors and practices of male sex workers and their foreign gay clients. While the flow of international remittances from 'Western Union daddies' to their Dominican 'boys' creates a continuous reminder of the utilitarian nature of the exchange, both sex workers and clients are motivated to camouflage this instrumentality in their construction of a more 'authentic,' fulfilling relationship. The article examines the consequences of this ambivalent negotiation for the emotional and economic organization of gay male sex tourism in the Caribbean.

We report first-year survival rates of 49 captive-reared Hispaniolan Parrots (Amazona ventralis) released in Parque Nacional del Este, Dominican Republic. Our goal was to learn about factors affecting postrelease survival. Specifically, we tested if survival was related to movements and whether modifying prerelease protocols influenced survival rates. We also estimated survival in the aftermath of Hurricane Georges (22 September 1998). Twenty-four parrots, fitted with radio-transmitters, were released between 14 September and 12 December 1997. Twenty-five more were released between 29 June and 16 September 1998. First-year survival rates were 30% in 1997 and 29% in 1998. Survival probability was related to bird mobility. In contrast to birds released in 1997, none of the 25 parrots released in 1998 suffered early postrelease mortality (i.e., 3-5 days after release). Two adjustments to prerelease protocols (increased exercise and reduced blood sampling) made in 1998 may have contributed to differences in mobility and survival between years. The reduction of early postrelease mortality in 1998 was encouraging, as was the prospect for higher first-year survival (e.g., 30% to 65%). Only one death was attributed to the immediate impact of the hurricane. Loss of foraging resources was likely a major contributor to ensuing mortality. Birds increased their mobility, presumably in search of food. Survival rates dropped 23% in only eight weeks posthurricane. This study underscores the value of standardized prerelease protocols, and of estimating survival and testing for factors that might influence it. Inferences from such tests will provide the best basis to make adjustments to a release program.

Full Text Available Today, Renewable Energy Sources (RES are a key pillar to achieving sustainable development, which is the main reason why energy projects are being carried out not only in developed countries but also in many emerging countries. Since the technical and financial risk remains a major barrier to financing renewable energy projects, several mechanisms are available to reduce risks on investment into clean energy projects. This paper discusses risk management tools in solar photovoltaic facilities based on the guide to the Project Management (PMBOK Guide. To do this, a combination of different decision-making methodologies will be carried out. These methodologies enable to not only extract the knowledge by experts but also to know the causes and effects that help to make the best decision. In order to do so, techniques to seek information (Delphi and Checklist as well as diagram techniques such as cause and effect diagrams or Strengths Weaknesses Opportunities and Threats (SWOT are applied. The categorization and prioritization of risks will be carried out through the Analytic Hierarchy Process (AHP. Finally, a sensitivity analysis will allow for providing consistency to the obtained results. A real case in the Dominican Republic will also be presented as case study.

Objectives. We assessed the effectiveness of 2 environmental–structural interventions in reducing risks of HIV and sexually transmitted infections (STIs) among female sex workers in the Dominican Republic. Methods. Two intervention models were implemented over a 1-year period: community solidarity in Santo Domingo and solidarity combined with government policy in Puerto Plata. Both were evaluated via preintervention–postintervention cross-sectional behavioral surveys, STI testing and participant observations, and serial cross-sectional STI screenings. Results. Significant increases in condom use with new clients (75.3%–93.8%; odds ratio [OR]=4.21; 95% confidence interval [CI]=1.55, 11.43) were documented in Santo Domingo. In Puerto Plata, significant increases in condom use with regular partners (13.0%–28.8%; OR=2.97; 95% CI=1.33, 6.66) and reductions in STI prevalence (28.8%–16.3%; OR = 0.50; 95% CI = 0.32, 0.78) were documented, as were significant increases in sex workers’ verbal rejections of unsafe sex (50.0%–79.4%; OR=3.86; 95% CI=1.96, 7.58) and participating sex establishments’ ability to achieve the goal of no STIs in routine monthly screenings of sex workers (OR=1.17; 95% CI=1.12, 1.22). Conclusions. Interventions that combine community solidarity and government policy show positive initial effects on HIV and STI risk reduction among female sex workers. PMID:16317215

Female sex workers (FSW) are disproportionately affected by HIV. Yet, few interventions address the needs of FSW living with HIV. We developed a multi-level intervention, Abriendo Puertas (Opening Doors), and assessed its feasibility and effectiveness among a cohort of 250 FSW living with HIV in the Dominican Republic. We conducted socio-behavioral surveys and sexually transmitted infection and viral load testing at baseline and 10-month follow-up. We assessed changes in protected sex and adherence to antiretroviral therapy (ART) with logistic regression using generalized estimating equations. Significant pre-post intervention changes were documented for adherence (72-89 %; p sex (71-81 %; p sex (AOR 1.76; 95 % CI 1.09-2.84). Illicit drug use was negatively associated with both ART adherence and protected sex. Abriendo Puertas is feasible and effective in improving behavioral HIV outcomes in FSW living with HIV.

The establishment of international collaborative research partnerships in times of infectious disease outbreaks of international importance has been considered an ethical imperative. Frail health research systems in low- and middle-income countries can be an obstacle to achieve the goal of knowledge generation and the search for health equity before, during and after infectious disease outbreaks. A qualitative case study was conducted to identify the challenges and opportunities facing the Dominican Republic with regards to developing international collaborative research partnerships in the context of the Zika outbreak and its ethical implications. Researchers conducted 34 interviews (n = 30 individual; n = 4 group) with 39 participants (n = 23 males; n = 16 females) representing the government, universities, international donor agencies, non-governmental organisations, community-based organisations and medical societies, in two metropolitan cities. Five international collaborative research projects related to the Zika virus were identified. Major ethical challenges were linked to the governance of health research, training of human resources, the institutionalisation of scientific activity, access to research funds and cultural aspects. Capacity-building was not necessarily a component of some partnership agreements. With few exceptions, local researchers were merely participating in data collection and less on defining the problem. Opportunities for collaborative work included the possibility of participation in international research consortiums through calls for proposals. The Dominican government and research stakeholders can contribute to the international response to the Zika virus through active participation in international collaborative research partnerships; however, public recognition of the need to embrace health research as part of public policy efforts is warranted. A working group led by the government and formed by national and

These data are consistent with antihaitianismo and the tendency for Dominicans to deny their African heritage in favor of their European Hispanic roots. The paper also explains how Dominicans’ ethnic flexibility in navigating “racialized” social space in the US is relevant to future census measurement of race and ethnicity.

Sharing medicine: the candidacy of medicines and other household items for sharing, Dominican Republic.

Directory of Open Access Journals (Sweden)

Full Text Available People share medicines and problems can result from this behavior. Successful interventions to change sharing behavior will require understanding people's motives and purposes for sharing medicines. Better information about how medicines fit into the gifting and reciprocity system could be useful in designing interventions to modify medicine sharing behavior. However, it is uncertain how people situate medicines among other items that might be shared. This investigation is a descriptive study of how people sort medicines and other shareable items.This study in the Dominican Republic examined how a convenience sample (31 people sorted medicines and rated their shareability in relation to other common household items. We used non-metric multidimensional scaling to produce association maps in which the distances between items offer a visual representation of the collective opinion of the participants regarding the relationships among the items. In addition, from a pile sort constrained by four categories of whether sharing or loaning the item was acceptable (on a scale from not shareable to very shareable, we assessed the degree to which the participants rated the medicines as shareable compared to other items. Participants consistently grouped medicines together in all pile sort activities; yet, medicines were mixed with other items when rated by their candidacy to be shared. Compared to the other items, participants had more variability of opinion as to whether medicines should be shared.People think of medicines as a distinct group, suggesting that interventions might be designed to apply to medicines as a group. People's differing opinions as to whether it was appropriate to share medicines imply a degree of uncertainty or ambiguity that health promotion interventions might exploit to alter attitudes and behaviors. These findings have implications for the design of health promotion interventions to impact medicine sharing behavior.

To determine the health literacy levels of persons living with human immunodeficiency virus (HIV) (PLWH) at a health clinic in the Dominican Republic (DR) and assess associations between health literacy, HIV-related knowledge, and health information behavior (how patients need, seek, receive, and use information). Cross-sectional, descriptive. Participants were 107 PLWH attending the Clinic. A theoretically based, 64-item survey assessing information behavior and HIV-related knowledge was administered in Spanish through individual interviews. Health literacy was assessed using the Short Assessment of Health Literacy-Spanish and English. On average, participants were 40.8 years old and had lived with HIV for 7.7 years. The majority (69.2%) had low health literacy. HIV-related knowledge and information behavior varied by health literacy level and uncertainty regarding a main indicator of disease progression, viral load, was demonstrated regardless of health literacy level. Participants with low health literacy were less likely to answer questions or answer questions correctly and many participants (39.2%) indicated viral transmission can occur through supernatural means. Findings demonstrate unmet information need and that information received may not always be understood. Methods to improve health education are needed to ensure patients receive health information in an understandable way. © 2017 Wiley Periodicals, Inc.

Social Vulnerability to Natural Hazards in Urban Systems. An Application in Santo Domingo (Dominican Republic

Full Text Available The concept of risk has become increasingly complex, and has been used not only in relation to the natural features of a region, but also to its socio-economic context. In this conceptualization, the latter directly influences the capacity of a community to cope with, recover from, and adapt to natural hazards. Conceiving vulnerability as a measure of a socio-ecological system’s resilience, and at the same time, as a multidimensional variable that changes in space and time, makes the study of the different ways in which natural hazards impact on society all the more urgent. This is particularly true for developing countries, where risk related to natural hazards affects populations and areas that must deal with stress conditions, such as humanitarian, social and military emergencies. This article presents a methodology for the analysis of social vulnerability, defined and experimented in the context of the international cooperation project “Estudio de la amenaza sísmica y vulnerabilidad física del Gran Santo Domingo”. The methodology, implemented through the employment of a Geographic Information System, led to the elaboration of a “Social Vulnerability Index” and a “Social Vulnerability Map”. These seek to describe the current condition of vulnerability of the city of Santo Domingo de Guzmán (Distrito Nacional in the Dominican Republic (DR, and are used to define context-related vulnerability scenarios, as well as to indicate the adequate set of mitigation objectives and actions. The results highlight the importance of using social vulnerability study as the point of departure for defining seismic-risk mitigation policies, emergency management, and territorial planning in order to reduce the impacts of disasters.

According to the World Health Organization, >200 million children in low- and middle-income countries experience developmental delays. However, household structure and parenting practices have been minimally explored as potential correlates of developmental delay in low- and middle-income countries, despite potential as areas for intervention. The objective of the study was to examine associations of developmental delays with use of World Health Organization-recommended parenting practices among a clinic-based cohort of children aged 6-60 months attending in La Romana, Dominican Republic. This study was conducted among 74 caregiver-child pairs attending the growth-monitoring clinic at Hospital Francisco Gonzalvo in June 2015. The Malawi Developmental Assessment Tool was adapted and performed on each child to assess socioadaptive, fine motor, gross motor, and language development. The IMCI Household Level Survey Questionnaire was used to assess parenting practices. Fisher's exact test was used to determine associations significant at P children had a delay in at least 1 developmental domain. Most caregivers used scolding (43.2%) or spanking (44%) for child discipline. Children who were disciplined by spanking and scolding were more likely to have language delay (P = .007) and socioadaptive delay (P = .077), respectively. On regression analysis, children with younger primary caregivers had 7 times higher odds of language delay (adjusted odds ratio [AOR]: 7.35, 95% confidence interval [CI]: 1.52-35.61) and 4 times greater odds of any delay (AOR: 4.72, 95% CI: 1.01-22.22). In addition, children punished by spanking had 5 times higher odds of having language delay (AOR: 5.04, 95% CI: 1.13-22.39). Parenting practices such as harsh punishment and lack of positive parental reinforcement were found to have strong associations with language and socioadaptive delays. Likewise, delays were also more common among children with younger caregivers. Copyright © 2017 Icahn

This paper summarizes the data presented by the representatives of Central America, Panama and the Dominican Republic at the II Regional Seminar on the Promotion of Breast-Feeding, held in Isla Contadora, Panama, April 25-29, 1983. The representatives of Costa Rica, Honduras and Panama provided up-to-date, representative data in regard to the breast-feeding practice. The average weaning age in the urban and rural areas of Costa Rica is 6 and 4 months, respectively. In Honduras and Panama, 43 and 17% of the infants from urban areas, and 21 and 37% of the babies from rural areas, respectively, were weaned before they reached four months of age. The need for availability of permanent systems to collect information on the breast-feeding practice in the different countries is pointed out. With regard to promotion actions, the absence of a national policy in favor of breast-feeding is evident. Moreover, in the national education systems, little importance is given to the subject. On the other hand, the advances achieved by some hospitals in favoring breast-feeding are mentioned. These include rooming in, the feeding of colostrum to newborns, and the establishment of human milk banks to feed premature babies whose mothers are unable to breast-feed them. Another acknowledged fact is that in the rural areas the agricultural home educators do not reinforce the breast-feeding practice. Also, there is a lack of information on the fulfillment of laws instituted for the protection of pregnant and lactating mothers, as far as pre and postnatal rest is concerned.

Full Text Available This contribution reports on the observation of enigmatic fibrous platinum-group minerals (PGM found within a chromitite body included in limonite (“floating chromitite” from Ni-laterites in the Dominican Republic. Fibrous PGM have a Ru-Os-Ir-Fe dominated composition and are characterized by fibrous textures explained by grain-forming fibers which are significantly longer (1–5 µm than they are wide (~100 nm. Back-scattered electron (BSE images suggest that these nanofibers are platinum-group elements (PGE-bearing and form <5 µm thick layers of bundles which are oriented orthogonal to grains’ surfaces. Trace amounts of Si are most likely associated with PGE-bearing nanofibers. One characteristic fibrous PGM was studied in detail: XRD analyses point to ruthenian hexaferrum. However, the unpolished fibrous PGM shows numerous complex textures on its surface which are suggestive for neoformation processes: (i features suggesting growth of PGE-bearing nanofibers; (ii occurrence of PGM nanoparticles within film material (biofilm? associated with PGE-bearing nanofibers; (iii a Si-rich and crater-like texture hosting PGM nanoparticles and an Ir-rich accumulation of irregular shape; (iv complex PGM nanoparticles with ragged morphologies, resembling sponge spicules and (v oval forms (<1 µm in diameter with included PGM nanoparticles, similar to those observed in experiments with PGE-reducing bacteria. Fibrous PGM found in the limonite may have formed due to supergene (bio-weathering of fibrous Mg-silicates which were incorporated into desulphurized laurite during stages of serpentinization.

Full Text Available In 1999, prevention of mother-to-child transmission (pMTCT using antiretrovirals was introduced in the Dominican Republic (DR. Highly active antiretroviral therapy (HAART was introduced for immunosuppressed persons in 2004 and for pMTCT in 2008. To assess progress towards MTCT elimination, data from requisitions for HIV nucleic acid amplification tests for diagnosis of HIV infection in perinatally exposed infants born in the DR from 1999 to 2011 were analyzed. The MTCT rate was 142/1,274 (11.1% in 1999–2008 and 12/302 (4.0% in 2009–2011 (P<.001, with a rate of 154/1,576 (9.8% for both periods combined. This decline was associated with significant increases in the proportions of women who received prenatal HAART (from 12.3% to 67.9% and infants who received exclusive formula feeding (from 76.3% to 86.1% and declines in proportions of women who received no prenatal antiretrovirals (from 31.9% to 12.2% or received only single-dose nevirapine (from 39.5% to 19.5%. In 2007, over 95% of DR pregnant women received prenatal care, HIV testing, and professionally attended delivery. However, only 58% of women in underserved sugarcane plantation communities (2007 and 76% in HIV sentinel surveillance hospitals (2003–2005 received their HIV test results. HIV-MTCT elimination is feasible but persistent lack of access to critical pMTCT measures must be addressed.

Full Text Available Kristin A Geers Childers, James R Palmieri, Mindy Sampson, Danielle Brunet Department of Microbiology, Infectious and Emerging Diseases, Edward Via College of Osteopathic Medicine, Blacksburg, VA, USA Abstract: Gastrointestinal infections impose a great and often silent burden of morbidity and mortality on poor populations in developing countries. The Dominican Republic (DR is a nation on the island of Hispaniola in the Caribbean Sea. Verón is located in La Alta Grácia province in the southeastern corner of the DR. Dominican and Haitian migrant workers come to Verón to work in Punta Cana, a tourist resort area. Few definitive or comprehensive studies of the prevalence of gastrointestinal parasitic infections have been published in the DR. Historically, most of the definitive studies of water-borne or soil-transmitted parasites in the DR were published more than 30 years ago. Presently, there is a high prevalence of gastrointestinal parasitic infections throughout the poorest areas of the DR and Haiti. In this study we report the prevalence of gastrointestinal protozoan and helminth parasites from children recruited from the Clínica Rural de Verón during 2008 through 2011. Each participant was asked to provide a fecal sample which was promptly examined microscopically for protozoan and helminth parasites using the Centers for Disease Control and Prevention (CDC fecal flotation technique to concentrate and isolate helminth ova and protozoan cysts. Of the 128 fecal samples examined, 127 were positive for one or more parasites. The age of the infected children ranged from 2–15 years; 61 were males and 66 were females. The only uninfected child was a 9 year old female. Percent infection rates were 43.8% for Ascaris lumbricoides, 8.5% for Enterobius vermicularis, 21.1% for Entamoeba histolytica, and 22.7% for Giardia duodenalis. Of the children examined, 7.8% had double infections. Any plan of action to reduce gastrointestinal parasites in

Full Text Available Drawing on research in Cuba and the Dominican Republic this paper explores the uses of intimacy in both the corporate sector and in romantic relationships. I use research with hotel workers and with people involved in sexual-affective exchanges connected to tourism to link intimacy to the political economic structures of transnational tourism. These are new spaces of analysis that present practices of transnational corporategenerated intimacy that combine love – or the exploitation of worker’s emotions − and labour. The central aim is to intertwine the intimate with the global, from the formal customer service policies of transnational hotels with the informal, on-the-ground, intimate encounters between tourists and hospitality workers. The commercialization of intimacy, including sexual-affective relations in the delivery of hospitality services, is linked to political and economic processes that are part of transnational tourism practices. This paper challenges the notion that sex tourism and sex work are individualistic practices that exist outside of the spaces of corporate global profit. It further posits that relationships where money is exchanged are not necessarily devoid of care and intimacy.Resumen: Encuentros íntimos: economías afectivas en Cuba y República Dominicana A partir de investigaciones en Cuba y la República Dominicana, este trabajo explora los usos de la intimidad, tanto en el sector empresarial como en las relaciones románticas.

Fringing reef margins of the Caribbean display a characteristic zonation in which Acropora palmata dominates shallow high-energy reef crests and Acropora cervicornis calmer fore-reef slopes and backreef lagoons. The dominance of acroporids across this zonation has been attributed to growth rates 5-100 times faster than other corals. However, the dominance and high accretion potential of acroporid reefs has a relatively recent geologic origin. Caribbean reefs changed profoundly in taxonomic composition, diversity, and dominance structure during late Pliocene and Pleistocene climatic change. These changes coincide with protracted climatic deterioration and cooling between 2.0 to 0.8 Ma, and the onset of high amplitude sea-level fluctuations ~400 ka. The Dominican Republic Drilling Project (DRDP) was initiated to determine how climate change and global high-amplitude sea level changes influenced depositional patterns in Pliocene to Recent reef systems of the Caribbean. A transect of 7 core borings (~700 m total depth) were collected along a transect of the southern coast of the DR in conjunction with over 20 km of ground penetrating radar (GPR) lines. New age constraints based on U/Th geochronometry and radiogenic Sr isotopes, combined with depositional lithofacies, faunal indicators, stable isotope profiles and GPR data have allowed us to correlate between wells and define the internal anatomy and stratal geometry of the individual reef sigmoids and sigmoid sets. The stacking of these sigmoid-shaped reefs produce lateral progradation of approximately 15 km with geometries that generally follow the highstand systems tract model of Pomar and Ward (1994). Based on existing age models eccentricity (high amplitude 100 kyr) sigmoids display increased aggradation and progradation potential compared to reef cycles driven by obliquity (41 kyr).

This study explores social cohesion as a strategy used by female sex workers to address layered HIV and sex work-related stigma. Data derive from a thematic analysis of 23 in-depth interviews and 2 focus groups with female sex workers living with HIV enrolled in a multi-level HIV/STI prevention, treatment and care intervention in Santo Domingo, Dominican Republic. Drawing on Foucault's conceptualisation of modern power, discipline and resistance, we argue that social cohesion provides the psychosocial space (of trust, solidarity and mutual aid) to subvert oppressive societal norms, enabling the reconstruction of identity. Among study participants, identity reconstruction happened through the production, repetition and performance of new de-stigmatised narratives that emerged and were solidified through collective interaction. Findings highlight that enabling the collective reconstruction of identity through social cohesion - rather than solely attempting to change individual beliefs - is a successful approach to addressing stigma.

To examine to what extent fresh vegetables imported into Switzerland represent carriers of extended-spectrum-β-lactamase (ESBL)-producing Enterobacteriaceae, 169 samples of different types of fresh vegetables imported into Switzerland from the Dominican Republic, India, Thailand, and Vietnam were analyzed. Overall, 25.4% of the vegetable samples yielded one or more ESBL-producing Enterobacteriaceae, 78.3% of which were multidrug resistant. Sixty isolates were obtained: Escherichia coli, 26; Klebsiella pneumoniae, 26; Enterobacter cloacae, 6; Enterobacter aerogenes, 1; and Cronobacter sakazakii, 1. We found 29 isolates producing CTX-M-15, 8 producing CTX-M-14, 7 producing CTX-M-55, 3 producing CTX-M-65, 1 each producing CTX-M-1, CTX-M-3, CTX-M-27, and CTX-M-63, 5 producing SHV-2, 3 producing SHV-12, and 1 producing SHV-2a. Four of the E. coli isolates belonged to epidemiologically important clones: CTX-M-15-producing B2:ST131 (1 isolate), D:ST405 (1 isolate), and D:ST38 (2 isolates). One of the D:ST38 isolates belonged to the extraintestinal enteroaggregative E. coli (EAEC) D:ST38 lineage. Two of the K. pneumoniae isolates belonged to the epidemic clones sequence type 15 (ST15) and ST147. The occurrence of antibiotic-resistant pathogenic and commensal Enterobacteriaceae in imported agricultural foodstuffs constitutes a source of ESBL genes and a concern for food safety. PMID:25724954

Calcidiol (25-hydroxyvitamin D) values are reported for 22 wild Ricord's iguanas (Cyclura ricordii) and seven wild rhinoceros iguanas (Cyclura cornuta cornuta). Calcitriol (1,25-hydroxyvitamin D) values are reported for 12 wild Ricord's iguanas and seven wild rhinoceros iguanas. These animals were captured as part of a larger health assessment study being conducted on Ricord's iguanas in Isla Cabritos National Park, Dominican Republic. A total of 13 captive rhinoceros iguanas held outdoors at Parque Zoológico Nacional were also sampled for comparison. Mean concentrations of 25-hydroxyvitamin D were 554 nmol/L (222 ng/ml) with a range of 250-1,118 nmol/L (100-448 ng/ml) for wild Ricord's iguanas, 332 nmol/L (133 ng/ml) with a range of 260-369 nmol/L (104-148 ng/ml) for wild rhinoceros iguanas, and 317 nmol/L (127 ng/ml) with a range of 220-519 nmol/L (88-208 ng/ml) for captive rhinoceros iguanas. On the basis of these results, serum concentrations of at least 325 nmol/L (130 ng/ml) for 25-hydroxyvitamin D should be considered normal for healthy Ricord's and rhinoceros iguanas.

Implications of the Central America-Dominican Republic-Free Trade Agreement for the nutrition transition in Central America.

To identify potential impacts of the Central America-Dominican Republic-Free Trade Agreement (CAFTA-DR) on food consumption patterns associated with the nutrition transition, obesity, and diet-related chronic diseases. Examination of CAFTA-DR agreement to identify measures that have the potential to affect food availability and retail prices. CAFTA-DR includes agreements on tariffs, tariff-rate quotas (TRQs), and sanitary and phytosanitary regulations with direct implications for the availability and prices of various foods. Agreements on investment, services, and intellectual property rights (IPR) are also relevant because they create a business climate more conducive to long-term investment by the transnational food industry. Trade liberalization under CAFTA-DR is likely to increase availability and lower relative prices of two food groups associated with the nutrition transition: meat and processed foods. These outcomes are expected to occur as the direct result of increased imports from the United States and increased production by U.S. companies based in Central America, and the indirect result of increased domestic meat production (due to increased availability of cheaper animal feed) and increased production of processed foods by domestic companies (due to a more competitive market environment). CAFTA-DR is likely to further the nutrition transition in Central America by increasing the consumption of meat; highly processed foods; and new, non-traditional foods. The public health community should be more aware of the implications of trade agreements for dietary health. Governments and related stakeholders should assess the coherence between changes fostered by specific trade agreements with national policies on diet and nutrition.

Full Text Available OBJECTIVE: To analyze household smoking-ban prevalence over time and predictors among communities in the Dominican Republic, historically a significant tobacco-growing country with few tobacco control regulations. METHODS: Baseline (2004 and follow-up surveillance surveys (2006, 2007 (each n > 1 000 randomly selected households conducted in six economically disadvantaged communities (three tobacco-growing and two each urban, peri-urban, and rural assessed household members’ demographics, health status, and household characteristics, including smoking restrictions. RESULTS: Between 2004 and 2007, household smoking-ban prevalence increased in all communities, with overall rates increasing from 23.9% (2004 to 45.3% (2007. Households with smokers adopted smoking bans at lower rates (6%-17% versus those without smokers (which had an adoption rate of 35%-58%. Logistic regression models demonstrated that the associations between allowing smoking in households with no members who smoked and being located in a tobacco-growing community, being a Catholic household, and having a member with a cardiovascular problem were statistically significant. The association between having a child under age 5 or a member with a respiratory condition and prohibiting smoking in the home was not statistically significant. CONCLUSIONS: Prevalence of households banning smoking increased in all communities but remained well below rates in industrialized countries. For low- and middle-income countries or those in early stages of tobacco control, basic awareness-raising measures (including surveillance activities may lead to statistically significant increases in household smoking-ban adoption, particularly among households with no smokers. An increase in household smoking-ban prevalence may result in changes in community norms that can lead to a further increase in the adoption of smoking bans. Having household members who smoke and being in a tobacco-growing community may

Modeling stem increment in individual Pinus occidentalis Sw. trees in La Sierra, Dominican Republic

One of the most common and important tree characteristics used in forest management decision-making is tree diameter-at-breast height (DBH). This paper presents results on an evaluation of two growth functions developed to model stem diameter increases in individual Pinus occidentalis Sw. trees in La Sierra, Dominican Republic. The first model was developed in order to predict future DBH (FDM) at different intervals of time and the other for predicting growth, that is, periodic annual diameter increment (PADIM). Each model employed two statistical techniques for fitting model parameters: stepwise ordinary least squares (OLS) regression, and mixed models. The two statistical approaches varied in how they accounted for the repeated measurements on individual trees over time, affecting standard error estimates and statistical inference of model parameters. Each approach was evaluated based on six goodness of- fit statistics, using both calibration and validation data sets. The objectives were 1) to determine the best model for predicting future tree DBH; 2) to determine the best model for predicting periodic annual diameter increment, both models using tree size, age, site index and different indices of competitive status; and 3) compare which of these two modeling approaches predicts better the future DBH. OLS provided a better fit for both of the growth functions, especially in regards to bias. Both models showed advantages and disadvantages when they were used to predict growth and future diameter. For the prediction of future diameter with FDM, accuracy of predictions were within one centimeter for a five-year projection interval. The PADIM presented negligible bias in estimating future diameter, although there was a small increase in bias as time of prediction increased. As expected, each model was the best in estimating the response variable it was developed for.. However, a closer examination of the distribution of errors showed a slight advantage of the FDM

Background Food insecurity contributes to poor health outcomes among people living with HIV. In Latin America and the Caribbean, structural factors such as poverty, stigma, and inequality disproportionately affect women and may fuel both the HIV epidemic and food insecurity. Methods We examined factors contributing to food insecurity among women living with HIV (WLHIV) in the Dominican Republic (DR). Data collection included in-depth, semi-structured interviews in 2013 with 30 WLHIV with indications of food insecurity who resided in urban or peri-urban areas and were recruited from local HIV clinics. In-person interviews were conducted in Spanish. Transcripts were coded using content analysis methods and an inductive approach to identify principal and emergent themes. Results Respondents identified economic instability as the primary driver of food insecurity, precipitated by enacted stigma in the labor and social domains. Women described experiences of HIV-related labor discrimination in formal and informal sectors. Women commonly reported illegal HIV testing by employers, and subsequent dismissal if HIV-positive, especially in tourism and free trade zones. Enacted stigma in the social domain manifested as gossip and rejection by family, friends, and neighbors and physical, verbal, and sexual abuse by intimate partners, distancing women from sources of economic and food support. These experiences with discrimination and abuse contributed to internalized stigma among respondents who, as a result, were fearful and hesitant to disclose their HIV status; some participants reported leaving spouses and/or families, resulting in further isolation from economic resources, food and other support. A minority of participants described social support by friends, spouses, families and support groups, which helped to ameliorate food insecurity and emotional distress.

We radio-tagged and released 49 captive-reared Hispaniolan Parrots (Amazona ventralis) in Parque Nacional del Este (PNE), Dominican Republic, during 1997 and 1998. Our primary objective was to develop a restoration program centered on using aviary-reared birds to further the recovery of the critically endangered Puerto Rican Parrot (A. vittata). Hurricane Georges made landfall over the release area on 22 September 1998 with sustained winds of 224 km/h, providing us with a unique opportunity to quantify responses of parrots to such disturbances. Quantitative data on such responses by any avian species are scarce, particularly for Amazona species, many of which are in peril and occur in hurricane-prone areas throughout the Caribbean. Mean home ranges of 18 parrots monitored both before and after the hurricane increased (P = 0.08) from 864 ha (CI = 689-1039 ha) pre-hurricane to 1690 ha (CI = 1003-2377 ha) post-hurricane. The total area traversed by all parrots increased > 300%, from 4884 ha pre-hurricane to 15,490 ha post-hurricane. Before Hurricane Georges, parrot activity was concentrated in coastal scrub, tall broadleaf forest, and abandoned agriculture (conucos). After the hurricane, parrots concentrated their activities in areas of tall broadleaf forest and abandoned conucos. Topographic relief, primarily in the form of large sinkholes, resulted in "resource refugia" where parrots and other frugivores foraged after the hurricane. Habitat use and movement patterns exhibited by released birds highlight the importance of carefully considering effects of season, topography, and overall size of release areas when planning psittacine restorations in hurricane-prone areas. ??

Evidence indicates that social cohesion is a successful strategy to improve consistent condom use (CCU) among female sex workers. However, the individual and layered or combined effect that various types of overlapping stigmas may have on CCU between female sex workers living with HIV and their clients and steady partners has not been analyzed. Drawing on the Abriendo Puertas cohort of female sex workers living with HIV in the Dominican Republic, we used structural equation modeling to test the hypothesis that both HIV stigma and sex work stigma mediate the association between social cohesion and CCU and that they have a layered effect. The results indicated that HIV stigma mediated the association between social cohesion and CCU with clients and partners, while sex work-related stigma did not. There was no evidence of a layered HIV stigma and sex work stigma effect, which may be due to methodological limitations to handle highly correlated latent variables. Findings highlight the need to address internalized HIV stigma within the context of community-based approaches to enhance their HIV prevention impact. This will help to reduce the risk of HIV re-infection with a new distinct HIV viral strain, STI infection, and onward HIV transmission among female sex workers living with HIV.

To assess the impact of health promotion programs and microcredit programs on three communities in the Dominican Republic. One community had only the health promotion program, one community had only the microcredit program, and one community had both a health promotion program and a microcredit program. This pilot project examined the hypothesis that the largest changes in 11 health indicators that were studied would be in the community with both a health promotion program and a microcredit program, that there would be intermediate changes in the community with only a health promotion program, and that the smallest changes would be in the community with only a microcredit program. The health promotion programs used community volunteers to address two major concerns: (1) the prevalent causes of mortality among children under 5 years of age and (2) women's health (specifically breast and cervical cancer screening). The microcredit program made small loans to individuals to start or expand small businesses. Outcome measures were based on comparisons for 11 health indicators from baseline community surveys (27 households surveyed in each of the three communities, done in December 2000 and January 2001) and from follow-up surveys (also 27 households surveyed in each of the three communities, in June and July 2002, after the health promotion program had been operating for about 13 months). Households were randomly chosen during both the baseline and follow-up surveys, without regard to their involvement in the microcredit or health promotion programs. The health indicators improved in all three communities. However, the degree of change was different among the communities (P microcredit and health promotion programs had the largest changes for 10 of the 11 health indicators. Multisector development is known to be important on a macroeconomic scale. The results of this pilot project support the view that multisector development is also important on a microeconomic level

Quantitative analyses exploring the relationship between masculinities and men's sexual risk behaviors have most commonly used one dimension of masculinities: men's gender ideology. Examining other dimensions may enhance our understanding of and ability to intervene upon this relationship. In this article, we examined the association between gender role conflict/stress (GRC/S)-men's concern about demonstrating masculine characteristics-and three different sexual risk behaviors (having two or more sex partners in the last 30 days; never/inconsistent condom use with non-steady partners; and drinking alcohol at last sex) among a sample of heterosexual men in the Dominican Republic who were participating in an HIV prevention intervention (n = 293). The GRC/S Scale we used was adapted for this specific cultural context and has 17 items (α = 0.75). We used logistic regression to assess the relationship between GRC/S and each sexual behavior, controlling for sociodemographic characteristics. In adjusted models, a higher GRC/S score was significantly associated with increased odds of having two or more sex partners in the past 30 days (AOR 1.33, 95 % CI 1.01-1.74), never/inconsistent condom use with non-steady partners (AOR 1.45, 95 % CI 1.04-2.01), and drinking alcohol at last sex (AOR 1.56, 95 % CI 1.13-2.17). These results highlight the importance of expanding beyond gender ideology to understanding the influence of GRC/S on men's sexual risk behaviors. Interventions should address men's concern about demonstrating masculine characteristics to reduce the social and internalized pressure men feel to engage in sexual risk behaviors.

The virtually unfolded sedimentary cover of the Cordilleras Central and Oriental in the eastern Dominican Republic (eastern Hispaniola, tropical North Atlantic) largely consists of Pliocene to Early Pleistocene mixed siliciclastics and carbonates. These deposits have been grouped into two laterally interfingering mapping units, the Yanigua and Los Haitises formations. The former (mainly siliciclastics) comprises marl, marly limestone, and minor conglomerate, sandstone, lignite, and carbonaceous clay and crops out closest to the basement. The Los Haitises Formation mainly consists of limestone and intercalating beds of marly limestone and marl. Lithological mapping at the 1:50,000 scale and facies analysis of twelve measured sections and of additional fourteen outcrops suggest that these deposits mainly formed on a shallow-water marine platform fringing the precursor reliefs of the Cordillera Oriental and the southeastern end of the Cordillera Central. Only a limited proportion of sediment formed in floodplains and marshes. Marl and marly limestone dominated the inner platform sediments. Terrigenous mud decreased away from the emergent basement and carbonate sedimentation dominated the more external platform. Corals, molluscs, echinoids, foraminifers, bryozoans, coralline algae, and Halimeda are the main components with varying amounts of carbonate mud. The platform was generally a low-energy environment with seagrass patches. In the inner platform, corals grew as isolated colonies or as small patch reefs dominated by Porites in marly and bioclastic substrates. Branching corals (Stylophora and Acropora) grew in extensive carpets in more distal areas. At least in the last stage of its development (Early Pleistocene), the platform was rimmed by a reef barrier similar to the Holocene Caribbean barrier reefs, with Acropora gr. palmata, A. cervicornis, Porites, Montastrea, Siderastrea, and Diploria as the main reef builders.

This purpose of this report was to examine the perceptions of medical students about the strengths, limitations, and recommendations for improvement of the first known student-run HIV/AIDS educational campaigns in the Dominican Republic (DR), as they relate to the added value applied to their educational training. A retrospective review was conducted on evaluation reports completed by five medical students who coordinated the implementation of three annual HIV/AIDS educational campaigns in five DR communities, between 2012 and 2014. Thematic analysis was used to identify emerging themes related to perceived strengths, limitations, and recommendations for improvement and develop an acronym related to program strengths as value added to medical education. Students highlighted that program strengths were the use of social media technology to facilitate communication and culture-based creativity to capture the attention of target audiences; and limitations were inadequate financial support and HIV-related cultural stigma, due to lack of disease knowledge and awareness or perceived contrasts between the federal system and faith-based community. Recommendations for program improvement, such as comprehensive event preparation and knowing the target audience, were described as key to maximizing the delivery of health messages. Our results highlighted that medical students gained expertise in the effective use of social media technology, culture-based creativity, and team synergy to disseminate HIV/AIDS health information across five DR communities. Students participated in these extracurricular community health campaigns, strengthening skills in communication, health advocacy, and leadership for their medical training. They served as human resources for health and can pave the way as future clinicians and indispensable health educators in local and national health collaborations.

Full Text Available In the Latin American context, the Dominican Republic displays high levels of civic engagement and political activism, yet they have not translated into a civil society that is able to exercise considerable influence in reforming the political system or enhancing democracy. Building on this observation, this article explores two questions. The first is if there is tendency toward dual participation in civic and political organizations, which reduces civil society’s ability to pressure political parties and the State. The second refers to the nature of the connections that civil society participants have with the State and with political parties. The analysis demonstrates that an important segment of the population that participates in civic associations also participates in political parties and in clientelist networks.República Dominicana registra un alto nivel de asociacionismo social y activismo político en el contexto latinoamericano. Esto, sin embargo, no se ha traducido en mayor capacidad de la sociedad civil dominicana para reformar el sistema político y mejorar la democracia. Con este planteamiento de fondo, se exploran dos preguntas. La primera es si existe una tendencia a la coparticipación en las organizaciones sociales y políticas que reduce la capacidad de presión de la sociedad civil sobre los partidos y el Estado. La segunda refiere a la naturaleza del vínculo de los participantes en organizaciones de la sociedad civil con el Estado y los partidos. El análisis muestra el involucramiento de un segmento de participantes en actividades cívicas, también en actividades partidarias y en redes clientelares.

The modification of hydrologic systems in coffee-dominated landscapes varies widely according to the degree of shade trees incorporated in coffee farms. Compared to mono-cropping systems, shade coffee can produce both on- and off-farm benefits in the form of soil retention, moderation of sediment transport, and lower hydropower generating costs. The Pico Duarte Coffee Region and surrounding Madres de Las Aguas (Mother of Waters) Conservation Area in the Dominican Republic is emblematic of the challenges and opportunities of ecosystem service management in coffee landscapes. Shade coffee poly-cultures in the region play an essential role in ensuring ecosystem function to conserve water resources, as well as provide habitat for birds, sequester carbon, and provide consumptive resources to households. To model the provision, use, and flow of ecosystem services from coffee farms in the region, an application of the Artificial Intelligence for Ecosystem Services (ARIES) model was developed with particular focus on sediment regulation. ARIES incorporates an array of techniques from data mining, image analysis, neural networks, Bayesian statistics, information theory, and expert systems to model the production, delivery, and demand for ecosystem services. Geospatial data on slope, soils, and vegetation cover is combined with on-farm data collection of coffee production, tree diversity, and intercropping of household food. Given hydropower production and river recreation in the region, the management of sedimentation through on-farm practices has substantial, currently uncompensated value that has received recent attention as the foundation for a payment for ecosystem services system. Scenario analysis of the implications of agro-forestry management choices on farmer livelihoods and the multiple beneficiaries of farm-provided hydrological services provide a foundation for ongoing discussions in the region between local, national, and international interests.

This study aims to study the distribution of contaminants in rivers that flow into the Caribbean Sea using chlorophyll-a (Chl-a) and suspended sediment (SS) as markers and ALOS AVNIR-2 satellite sensor data. The Haina River (HN) and Ozama and Isabela Rivers (OZ-IS) that flow through the city of Santo Domingo, the capital of the Dominican Republic, were chosen. First, in situ spectral reflectance/Chl-a and SS datasets obtained from these rivers were acquired in March 2011 (case A: with no rain influence) and June 2011 (case B: with rain influence), and the estimation algorithm of Chl-a and SS using AVNIR-2 data was developed from the datasets. Moreover, the developed algorithm was applied to AVNIR-2 data in November 2010 for case A and August 2010 for case B. Results revealed that for Chl-a and SS estimations under cases A and B conditions, the reflectance ratio of AVNIR-2 band 4 and band 3 (AV4/AV3) and the reflectance of AVNIR-2 band 4 (AV4) were effective. The Chl-a and SS mapping results obtained using AVNIR-2 data corresponded with the field survey results. Finally, an outline of the distribution of contaminants at the mouth of the river that flows into the Caribbean Sea was obtained for both rivers in cases A and B.

Mangroves are recognized to possess a variety of ecosystem services including high rates of carbon sequestration and storage. Deforestation and conversion of these ecosystems continue to be high and have been predicted to result in significant carbon emissions to the atmosphere. Yet few studies have quantified the carbon stocks or losses associated with conversion of these ecosystems. In this study we quantified the ecosystem carbon stocks of three common mangrove types of the Caribbean as well as those of abandoned shrimp ponds in areas formerly occupied by mangrove-a common land-use conversion of mangroves throughout the world. In the mangroves of the Montecristi Province in Northwest Dominican Republic we found C stocks ranged from 706 to 1131 Mg/ha. The medium-statured mangroves (3-10 m in height) had the highest C stocks while the tall (> 10 m) mangroves had the lowest ecosystem carbon storage. Carbon stocks of the low mangrove (shrub) type (carbon-rich soils as deep as 2 m. Carbon stocks of abandoned shrimp ponds were 95 Mg/ha or approximately 11% that of the mangroves. Using a stock-change approach, the potential emissions from the conversion of mangroves to shrimp ponds ranged from 2244 to 3799 Mg CO2e/ha (CO2 equivalents). This is among the largest measured C emissions from land use in the tropics. The 6260 ha of mangroves and converted mangroves in the Montecristi Province are estimated to contain 3,841,490 Mg of C. Mangroves represented 76% of this area but currently store 97% of the carbon in this coastal wetland (3,696,722 Mg C). Converted lands store only 4% of the total ecosystem C (144,778 Mg C) while they comprised 24% of the area. By these metrics the replacement of mangroves with shrimp and salt ponds has resulted in estimated emissions from this region totaling 3.8 million Mg CO2e or approximately 21% of the total C prior to conversion. Given the high C stocks of mangroves, the high emissions from their conversion, and the other important

Expansion of the tourism industry in the Dominican Republic has had far-reaching health consequences for the local population. Research suggests families with one or more members living in tourism areas experience heightened vulnerability to HIV/STIs due to exposure to tourism environments, which can promote behaviors such as commercial and transactional sex and elevated alcohol use. Nevertheless, little is known about how tourism contexts influence family dynamics, which, in turn, shape HIV risk. This qualitative study examined family relationships through in-depth interviews with 32 adults residing in Sosúa, an internationally known destination for sex tourism. Interviewees situated HIV risk within a context of limited employment opportunities, high rates of migration, heavy alcohol use, and separation from family. This study has implications for effective design of health interventions that make use of the role of the family to prevent HIV transmission in tourism environments.

Glowing seashells: diversity of fossilized coloration patterns on coral reef-associated cone snail (Gastropoda: Conidae shells from the Neogene of the Dominican Republic.

Directory of Open Access Journals (Sweden)

Jonathan R Hendricks

Full Text Available The biology of modern Conidae (cone snails--which includes the hyperdiverse genus Conus--has been intensively studied, but the fossil record of the clade remains poorly understood, particularly within an evolutionary framework. Here, ultraviolet light is used to reveal and characterize the original shell coloration patterns of 28 species of cone snails from three Neogene coral reef-associated deposits from the Cibao Valley, northern Dominican Republic. These fossils come from the upper Miocene Cercado Fm. and lower Pliocene Gurabo Fm., and range in age from about 6.6-4.8 Ma. Comparison of the revealed coloration patterns with those of extant species allow the taxa to be assigned to three genera of cone snails (Profundiconus, Conasprella, and Conus and at least nine subgenera. Thirteen members of these phylogenetically diverse reef faunas are described as new species. These include: Profundiconus? hennigi, Conasprella (Ximeniconus ageri, Conus anningae, Conus lyelli, Conus (Atlanticonus? franklinae, Conus (Stephanoconus gouldi, Conus (Stephanoconus bellacoensis, Conus (Ductoconus cashi, Conus (Dauciconus garrisoni, Conus (Dauciconus? zambaensis, Conus (Spuriconus? kaesleri, Conus (Spuriconus? lombardii, and Conus (Lautoconus? carlottae. Each of the three reef deposits contain a minimum of 14-16 cone snail species, levels of diversity that are similar to modern Indo-Pacific reef systems. Finally, most of the 28 species can be assigned to modern clades and thus have important implications for understanding the biogeographic and temporal histories of these clades in tropical America.

2017-01-01

While numerous studies of dam reservoirs contamination are reported world-wide, we present a missing link in the study of reservoirs sourced from multiple river catchments. In such reservoirs, different point sources of contaminants and variable composition of their sedimentary matrices add to extremely complex geochemical patterns. We studied a unique, step-wise filled Nové Mlýny dam reservoir, Czech Republic, which consists of three interconnected sub-basins. Their source areas are located in units with contrasting geology and different levels and sources of contamination. The aim of this study is to provide an insight into the provenance of the sediment, including lithogenic elements and anthropogenic pollutants, to investigate the sediment dispersal across the reservoir, and to assess the heavy metal pollution in each basin. The study is based on multi-proxy stratigraphic analysis and geochemistry of sediment cores. There is a considerable gradient in the sediment grain size, brightness, MS and geochemistry, which reflects changing hydrodynamic energy conditions and primary pelagic production of CaCO 3 . The thickness of sediments generally decreases from proximal to distal parts, but underwater currents can accumulate higher amounts of sediments in distal parts near the thalweg line. Average sedimentation rates vary over a wide range from 0.58cm/yr to 2.33cm/yr. In addition, the petrophysical patterns, concentrations of lithogenic elements and their ratios made it possible to identify two main provenance areas, the Dyje River catchment (upper basin) and the Svratka and Jihlava River catchments (middle and lower basin). Enrichment factors (EF) were used for distinguishing the anthropogenic element contribution from the local background levels. We found moderate Zn and Cu pollution (EF ~2 to 5) in the upper basin and Zn, Cu and Pb (EF ~2 to 4.5) in the middle basin with the peak contamination in the late 1980s, indicating that the two basins have different

Background Voluntary Medical Male Circumcision (VMMC) is an effective strategy to reduce the risk of HIV infection. Studies conducted in the Dominican Republic (DR) suggest that acceptability of VMMC among men may be as high as 67%. The goal of this clinical trial was to assess the acceptability, uptake and safety for VMMC services in two areas of high HIV prevalence in the country. Methods This was a single-arm, non-randomized, pragmatic clinical trial. Study personnel received background information about the risks and benefits of VMMC and practical training on the surgical technique. A native speaking research assistant administered a questionnaire of demographics, sexual practices and knowledge about VMMC. One week after the surgery, participants returned for wound inspection and to answer questions about their post-surgical experience. Results 539 men consented for the study. Fifty seven were excluded from participation for medical or anatomical reasons and 28 decided not to have the procedure after providing consent. A total of 454 men were circumcised using the Forceps Guided Method Under Local Anesthesia. The rate of adverse events (AE) was 4.4% (20% moderate, 80% mild). There were no serious AEs and all complications resolved promptly with treatment. Eighty eight percent of clients reported being “very satisfied” and 12% were “somewhat satisfied” with the outcome at the one-week postoperative visit. Conclusions Recruitment and uptake were satisfactory. Client satisfaction with VMMC was high and the rate of AEs was low. Roll out of VMMC in targeted areas of the DR is feasible and should be considered. Trial Registration ClinicalTrials.gov NCT02337179 PMID:26367187

Food insecurity is an important risk factor for overweight and obesity among low-income populations in high income countries, but has not been well-studied among people living with HIV (PLHIV), particularly in resource-poor settings. To explore the association between food insecurity and overweight and obesity among PLHIV in the Dominican Republic, we conducted a cross-sectional study of 160 HIV-infected adults between March-December 2012 in four geographically-dispersed health centers (Santo Domingo, Puerto Plata, San Juan, and Higuey). We collected information on household food insecurity, anthropometric measurements, and socio-demographic data and ran descriptive and multivariate analyses, controlling for fixed effects of clinics and using robust standard errors. Mean age ± SD of participants was 39.9 ± 10.5 years; 68% were women, and 78% were on antiretroviral therapy (ART). A total of 58% reported severe household food insecurity. After controlling for age, gender, income, having children at home, education, and ART status, severe food insecurity was associated with increased body mass index (BMI) (β = 1.891, p = 0.023) and body fat (β = 4.004, p = 0.007). Age and female gender were also associated with increased body fat (β = 0.259, p insecurity was associated with an increased odds of 3.060 (p = 0.013); no other covariates were independently associated with overweight. The association of severe food insecurity with increased BMI, body fat, and overweight among PLHIV has important implications for clinical care as well as food security and nutrition interventions in resource-poor settings. Integrated programs that combine nutrition education or counseling with sustainable approaches to addressing food insecurity among PLHIV are needed to improve long-term health outcomes of this vulnerable population.

[Haitian migration to Santo Domingo].

This work examines the history of Haitian migration to the Dominican Republic, the central role of Haitian migration in Dominican society, working conditions of Haitian migrants in the Dominican Republic, and the relationship of the migration to economic development on the island of Hispaniola. Lack of data, the difficulty of measuring illegal movement, and the problem of defining Haitians in Santo Domingo have impeded understanding of migration to the Dominican Republic. It is believed by many authorities that Haitian migration to Santo Domingo is considerable and perhaps exceeds that to the US. Haitian migration to the Dominican Republic began after 1915 with the fall of the Haitian president, a worsening of economic conditions partly caused by stagnation in the agricultural sector, and the newly dominant role of the US in Haitian economic affairs. The Great Depression of the 1930s was a direct antecedent of the massacre of Haitians by Dominican police in which some 30 thousand persons were killed; the economic recession of the early 1980s has also caused an outburst of antiHaitian feeling in the Dominican Republic although 80% of laborers in the sugar industry are Haitians. Sugar is extremely important to the Dominican economy: in 1974, sugar covered 12% of cultivated land, produced 40% of foreign exchange earnings, and was responsable for 21% of taxable income. Dominicans however refuse to work in sugar plantations under the current technological. conditions and wage system. Although the government periodically demands the Dominicanization of the sugar work force, no such changes have been made. Sugar will probably continue to play a decisive role in the generation of foreign exchange despite introduction of more technologically advanced sectors which benefit from better prices in the international market. Possibilities of mechanizing sugar production in the Dominican Republic appear remote, and failure to modernize an important sector of the economy has

Geothermal resources in the Asal Region, Republic of Djibouti: An update with emphasis on reservoir engineering studies

Three independent geothermal systems have been identified, so far, in the Asal region of the Republic of Djibouti (i.e. Gale le Goma, Fiale and South of Lake). Six deep wells have been drilled in the region, the first two in 1975 and the others in 1987-88. Well A2 was damaged and wells A4 and A5 encountered impermeable yet very hot (340-365 C) rocks. Wells A1, A2, A3 and A6 produce highly saline (120 g/L TDS) fluids leading to mineral scaling. Well test data indicate that the reservoir might be producing from fractured and porous zones. The estimated permeability-thickness of the deep Gale le Goma reservoir is in the 3-9 darcy-meter range. Lumped-parameter modeling results indicate that well A3 should be operated at about 20 kg/s total flow rate and that injection should be considered to reduce pressure drawdown. The estimated power generation potential of well A3 is 2.5 MWe, and that of all Asal high-temperature hydrothermal systems is between 115 and 329 MWe for a 25-year exploitation period. (author)

Previously, we reported the use of quinolones in broiler chickens resulted in residues in retail poultry meat obtained from nine districts in the Santiago Province of the Dominican Republic. Residues in poultry products are a concern due to consumer allergies and the potential to develop antibiotic-resistant bacteria. Given the use of quinolones in poultry production and our previous findings in poultry meat, the objective of this study was to evaluate the presence of quinolone residues in eggs. Samples were collected from 48 different farms located in three of the four municipalities (Moca, Cayetano Germosén, and Jamao) of the Espaíllat Province. Each farm was sampled three times between July and September for a total of 144 samples. Samples were evaluated qualitatively and quantitatively for quinolone residues using the Equinox test. Operation systems (cage or floor), seasonality, and location were considered along with egg-producer sizes that were defined as small scale, eggs per day; medium scale, 30,000 to 60,000 eggs per day; or large scale, >60,000 eggs per day. From small-, medium-, and large-scale producers, 69, 50, and 40% of samples were positive for quinolone residues, respectively. A greater number of samples were positive (61%) in floor-laying hen producers compared with those using cages (40%). In the Jamao municipality, 67% of the samples were positive compared with Moca and Cayetano Germosén, where 56 and 25% of samples were positive, respectively. Sampling time had an effect on percent positives: samples collected in July, August, and September were 71, 19, and 63% positive, respectively. Overall, 51% of the samples obtained from eggs produced in the province of Espaíllat were positive for quinolone residues at levels higher than the maximum limits for edible tissue established by the regulatory agencies, including the European Union and U.S. Department of Agriculture. The results obtained from this research confirmed the presence of quinolone

Based on a set of various studies, an evaluation of the type of upper Cretaceous reservoir in the Pravoberezhnoe field is given. Compared to other fields in the Chechen Ingush Autonomous Soviet Socialist Republic, the upper Cretaceous productive deposits at this field are characterized by poorer reservoir properties. The set of all data indicates that the upper Cretaceous reservoir is analogous to reservoirs of equal age in existing fields in this republic and are cavernous fissured type.

Discovery of Ni-smectite-rich saprolite at Loma Ortega, Falcondo mining district (Dominican Republic): geochemistry and mineralogy of an unusual case of "hybrid hydrous Mg silicate - clay silicate" type Ni-laterite

Hydrous Mg silicate-type Ni-laterite deposits, like those in the Falcondo district, Dominican Republic, are dominated by Ni-enriched serpentine and garnierite. Recently, abundant Ni-smectite in the saprolite zone have been discovered in Loma Ortega, one of the nine Ni-laterite deposits in Falcondo. A first detailed study on these Ni-smectites has been performed (μXRD, SEM, EPMA), in addition to a geochemical and mineralogical characterisation of the Loma Ortega profile (XRF, ICP-MS, XRD). Unlike other smectite occurrences in laterite profiles worldwide, the Loma Ortega smectites are trioctahedral and exhibit high Ni contents never reported before. These Ni-smectites may be formed from weathering of pyroxene and olivine, and their composition can be explained by the mineralogy and the composition of the Al-depleted, olivine-rich parent ultramafic rock. Our study shows that Ni-laterites are mineralogically complex, and that a hydrous Mg silicate ore and a clay silicate ore can be confined to the same horizon in the weathering profile, which has significant implications from a recovery perspective. In accordance, the classification of "hybrid hydrous Mg silicate - clay silicate" type Ni-laterite deposit for Loma Ortega would be more appropriate.

New policies and measures for saving a great manmade reservoir providing drinking water for 20 million people in the Republic of Korea.

Water quality of the Paldang reservoir, the largest drinking water supply source in the Republic Korea provides raw water for about 20 million people living in Seoul Metropolitan area. Water quality has been deteriorating mainly due to improperly treated livestock waste and domestic wastewater discharged from motels, restaurants, and private homes. A recent survey conducted by the Ministry of Environment (MOE) showed that the water quality of this reservoir has been identified as Class III must contain less than 6 ppm of BOD, which will require advanced purification treatment before it can be used as drinking water. The MOE also announced that this water source would no longer be potable unless wastewater in the catchment is treated efficiently. To protect drinking water resources, the MOE has set up comprehensive management. These programmes include new regulations, measures, land use planning and economic incentives.

The historical antagonism between Haiti and the Dominican Republic is no doubt known to readers of this journal, as is the recent upsurge in tension between the two countries, which culminated in the expulsion of tens of thousands of Haitian immigrants from the Dominican Republic, from June to September 1991. The quickening pace of events, added to the worsening spiral of economic hardship gripping both nations, threaten to render obsolete even the most recent analyses of relations between the two countries. Even so, against the background of an increasingly acrimonious debate between the Dominican government and international human rights organizations accusing it of enslaving Haitian immigrants in the cane flelds, the appearance of two works by long-time students of the migration of Haitians as cane workers to the Dominican Republic is particularly timely.

Examining the policy climate for HIV prevention in the Caribbean tourism sector: a qualitative study of policy makers in the Dominican Republic.

The Caribbean has the highest prevalence rates of HIV/AIDS outside sub-Saharan Africa, and a broad literature suggests an ecological association between tourism areas and sexual vulnerability. Tourism employees have been shown to engage in high rates of sexual risk behaviours. Nevertheless, no large-scale or sustained HIV prevention interventions have been conducted within the tourism industry. Policy barriers and resources are under-studied. In order to identify the policy barriers and resources for HIV prevention in the tourism sector, our research used a participatory approach involving a multisectoral coalition of representatives from the tourism industry, government, public health and civil society in the Dominican Republic. We conducted 39 in-depth semi-structured interviews with policy makers throughout the country focusing on: prior experiences with HIV prevention policies and programmes in the tourism sector; barriers and resources for such policies and programmes; and future priorities and recommendations. Findings suggest perceptions among policy makers of barriers related to the mobile nature of tourism employees; the lack of centralized funding; fear of the 'image problem' associated with HIV; and the lack of multisectoral policy dialogue and collaboration. Nevertheless, prior short-term experiences and changing attitudes among some private sector tourism representatives suggest emerging opportunities for policy change. We argue that the time is ripe for dialogue across the public-private divide in order to develop regulatory mechanisms, joint responsibilities and centralized funding sources to ensure a sustainable response to the HIV-tourism linkage. Policy priorities should focus on incorporating HIV prevention as a component of occupational health; reinforcing workers' health care rights as guaranteed by existing law; using private sector tourism representatives who support HIV prevention as positive role models for national campaigns; and

Calzada, Esther J; Eyberg, Sheila M

2002-09-01

Explored self-reported parenting in a Hispanic sample of mothers living in the mainland United States using a cultural framework. Participants were 130 immigrant or first-generation Dominican and Puerto Rican mothers with a child between the ages of 2 and 6 years. Mothers completed questionnaires related to their parenting behavior and also filled out a detailed demographic form and a measure of acculturation. Results suggested that both Dominican and Puerto Rican mothers engage in high levels of praise and physical affection and low levels of harsh, inconsistent, and punitive parenting behaviors. Dominican and Puerto Rican parenting was similar on measures of authoritarian and permissive parenting, but differences emerged on a measure of authoritative parenting and when parenting was considered at the more detailed level of individual behaviors. Parenting was related to several demographic characteristics, including father's education level and child age; more specifically, higher paternal education and younger age of the child were related to higher levels of authoritative parenting by mothers. Parenting and acculturation were generally not related. Discussion focused on a culturally sensitive interpretation of normative parenting among Dominican and Puerto Rican mothers.

2008-01-01

Background A growing literature on Latino’s beliefs about cancer focuses on the concept of fatalismo (fatalism), despite numerous conceptual ambiguities concerning its meaning, definition, and measurement. This study explored Latina women’s views on breast cancer and screening within a cultural framework of destino (“destiny”), or the notion that both personal agency and external forces can influence health and life events Methods Semi-structured interviews were conducted with 25 Latinas from the Dominican Republic aged 40 or over. Results Respondents reported complex notions of health locus of control that encompassed both internal (e.g., individual action) and external (e.g., the will of God) forces shaping breast cancer prevention efforts. Furthermore, women actively participated in screening because they believed that cancer could become a death sentence if diagnosed late or left untreated. Discussion In contrast to simplistic notions of “fatalism”, our analysis suggests complex strategies and beliefs regarding breast cancer and cancer screening that speak of resiliency rather than hopelessness.

To examine how alcohol-related HIV risk behaviors within MSM sex workers' social networks (SN) may be associated with individual risk behaviors, respondent-driven and venue-based sampling were used to collect demographic, behavioral and SN characteristics among MSM sex workers in Santo Domingo and Boca Chica (N = 220). The majority of participants reported problem drinking (71.0%) or alcohol use at their last sexual encounter (71.4%). Self-reported problem drinking was associated with SN characteristics (at least one member who recently got drunk aOR = 7.5, no religious/spiritual adviser aOR = 3.0, non-sexual network density aOR = 0.9), while self-reported alcohol use at last sex was associated with individual (drug use at last sex aOR = 4.4) and SN characteristics (at least one member with previous HIV/STI testing aOR = 4.7). Dominican MSM sex workers reported high alcohol use, which may increase their risk for HIV. A better understanding of SN factors associated with individual risk behaviors can help guide appropriate intervention development.

Eutrophication study at the Panjiakou-Daheiting Reservoir system, northern Hebei Province, People's Republic of China: Chlorophyll-a model and sources of phosphorus and nitrogen

Concentrations, loads, and sources of nitrate and total phosphorus were investigated at the Panjiakou and Daheiting Reservoir system in northern Hebei Province, People's Republic of China. The Luan He River is the primary source of water to these reservoirs, and the upstream watershed has a mix of land uses including agriculture, forest, and one large urban center. The reservoirs have a primary use for storage of drinking water and partially supply Tianjin City with its annual needs. Secondary uses include flood control and aqua culture (fish cages). The response of the reservoir system from phosphorus input, with respect to chlorophyll-a production from algae, was fitted to a model of normalized phosphorus loading that regresses the average summer-time chlorophyll-a concentration to the average annual phosphorus concentration of the reservoir. Comparison of the normalized phosphorus loading and chlorophyll-a response of this system to other reservoirs throughout the world indicate a level of eutrophication that will require up to an approximate 5–10-fold decrease in annual phosphorus load to bring the system to a more acceptable level of algal productivity. Isotopes of nitrogen and oxygen in dissolved nitrate were measured from the headwater streams and at various locations along the major rivers that provide the majority of water to these reservoirs. Those isotopic measurements indicate that the sources of nitrate change from natural background in the rivers to animal manure and septic waste upstream of the reservoir. Although the isotopic measurements suggest that animal and septic wastes are a primary source of nutrients, measurements of the molar ratio of nitrogen to phosphorus are more indicative of row-cropping practices. Options for reduction of nutrient loads include changing the management practices of the aqua culture, installation of new sewage treatment systems in the large urbanized area of the upper watershed, and agricultural management practices

Behavior change communication often focuses on individual-level variables such as knowledge, perceived risk, self-efficacy, and behavior. A growing body of evidence suggests, however, that structural interventions to change the policy environment and environmental interventions designed to modify the physical and social environment further bolster impact. Little is known about the cost-effectiveness of such comprehensive intervention programs. In this study we use standard cost analysis methods to examine the incremental cost-effectiveness of two such interventions conducted in the Dominican Republic in sex establishments. In Santo Domingo the intervention was environmental; in Puerto Plata it was both environmental and structural (levying financial sanctions on sex establishment owners who failed to follow the intervention). The interventions in both sites included elements found in more conventional behavior change communication (BCC) programs (e.g., community mobilization, peer education, educational materials, promotional stickers). One key aim was to examine whether the addition of policy regulation was cost-effective. Data for the analysis were gleaned from structured behavioral questionnaires administered to female sex workers and their male regular paying partners in 41 sex establishments conducted pre- and post-intervention (1 year follow-up); data from HIV sentinel surveillance, STI screening results conducted for the intervention; and detailed cost data we collected. We estimated the number of HIV infections averted from each of the two intervention models and converted these estimates to the number of disability life years saved as compared with no intervention. One-way, two-way, three-way, and multivariate sensitivity analysis were conducted on model parameters. We examine a discount rate of 0%, 3% (base case), and 6% for future costs and benefits. The intervention conducted in Santo Domingo (community mobilization, promotional media, and interpersonal

This paper focuses on a mixed-method approach to quantifying qualitative data from the results of an ongoing NIDA-funded ethnographic study entitled “Migration, Tourism, and the HIV/Drug-Use Syndemic in the Dominican Republic”. This project represents the first large-scale mixed method study to identify social, structural, environmental, and demographic factors that may contribute to ecologies of health vulnerability within the Caribbean tourism zones. Our research has identified deportation history as a critical factor contributing to vulnerability to HIV, drugs, mental health problems, and other health conditions. Therefore, understanding the movements of our participants became a vital aspect of this research. This paper describes how we went about translating 37 interviews into visual geographic representations. These methods help develop possible strategies for confronting HIV/AIDS and problematic substance use by examining the ways that these epidemics are shaped by the realities of people’s labor migration and the spaces they inhabit. Our methods for mapping this qualitative data contribute to the ongoing, broadening capabilities of using GIS in social science research. A key contribution of this work is its integration of different methodologies from various disciplines to help better understand complex social problems. PMID:27656039

The Dominican population has a double-emigration pathway: one is to the USA, by proximity, and the other is to Spain, by sociocultural identification. Our aim was to determine attitudes toward living organ donation among Dominicans residing in Florida (USA) and Spain. All study participants were at least 15 years old and living in either Florida (USA) or Spain, and stratified by gender and age. A questionnaire on attitudes toward living kidney donation ("PCID-LKD Ríos") was used. The support of immigrant associations in Florida and Spain was required to advise on survey locations. Data obtained were anonymized and self-administered. The study questionnaire was completed by 123 Dominicans, 68% of whom were in favor of living related kidney donation. There were differences (P = .004) according to the country of residence. Eighty-one percent of Spain's Dominican residents were in favor, compared with 56% of Florida's residents. Factors associated with attitude toward donation were level of education (P donation (P = .006), attitude toward cadaveric organ donation (P donation (P = .046). Attitudes toward living kidney donation among immigrant Dominicans varies between Spain and the USA, with the former showing a more positive view. Copyright © 2017 Elsevier Inc. All rights reserved.

Full Text Available The tubenose goby (Proterorhinus semilunaris is a gobiid species currently extending its area of distribution in Central Europe. The objective of the study was to evaluate the annual pattern of its feeding habits in the newly colonised habitats of the Mušov reservoir on the Dyje River (the Danube basin, Czech Republic with respect to natural food resources. In the reservoir, tubenose goby has established a numerous population, densely colonising stony rip-rap banks. Its diet was exclusively of animal origin with significant dominance of and preference for two food items – chironomid (Chironomidae larvae and waterlouse (Asellus aquaticus, which contributed 40.2 and 27.6%, respectively, to the total food bulk ingested. The index of preponderance for the two items was also very high, amounting to 73.8 and 26.5, respectively. In the annual pattern, a remarkable preference for chironomid larvae was recorded in the summer period whilst waterlouse were consumed predominantly in winter months. The proportion of other food items was rather marginal – only corixids, copepods, ceratopogonids and cladocerans were of certain minor importance with proportions of 5.4, 4.3, 4.1 and 3.9%, respectively. Certain signs of cannibalism were also recorded, with 0.9 and 0.2% of the diet consisting of their own progeny and eggs, respectively.

Radiation safety actuality in Republic of Moldova

Kuharuk, E.S.

2011-01-01

Radioecological monitoring issues and radiation safety are actual in the Republic of Moldova. Japan events show us the possibility of natural disasters. Republic of Moldova is surrounded by 8 NPPs, the closest being at the distance of 160 km. Moldovas territory is in seismic zone where underground earthquake shocks reaches 7 points or more. Thatis why radiation safety and radioecological monitoring is actual in our republic. Traces of Chernobyl were left in Moldovas soils. The fallouts of radio nuclides formed on the soil surfaces in the Republic of Moldova following the Chernobyl Nuclear Power Station Accident have been continuously affected by attacks of both natural and technicaly generated agents since the time of fallout. During the past decade a shift in emphasis has taken place regarding the need for more complete and accurate information on reservoir sedimentation. Classical sedimentation surveys involve repeated field measurement and, therefore, this is probably the most costly and time consuming method. The application of radio nuclides, particularly Cs 137, for water erosion and sedimentation studies in Republic of Moldova has not been attempted so far. This paper presents the results obtained on reservoir sedimentation rates in an area subjected to wide range in land degradation dy sheet-rill erosion. The profil characteristics support the assumption that in most undisturbed sites there is a sharp decline in Cs 137 activity with increasing dept. Such an asymmetrical distribution of the Cs 137 would suggest a standard pattern in the form of a cantilever. If the validity of this assamption is accepted it is possible to define two major types of Cs 137 cantilever distribution: shallow and deep buried cantilever. The main criterion in classifying these pattents lies generally in the shape of Cs 137 depth profile and particularly in burial magnitude of Cs 137 peak derived from Chernobyl. Hills area has been impacted by greatest sendimentation. This regional

How accurate is our misinformation? A randomized comparison of four survey interview methods to measure risk behavior among young adults in the Dominican Republic

Full Text Available Objective: To identify the most effective survey interview method for measuring risk behavior among young adults in the Dominican Republic. Methods: 1200 young adults were randomized to one of four different survey interview methods: two interviewer-assisted methods [face-to-face interview (FTFI, and computer-assisted telephone interview (CATI], and two self-administered methods [self-administered interview (SAI, and audio computer-assisted, self-administered interview (ACASI]. Youth were asked about a wide range of youth-specific risk behaviors, including violence, substance use, as well as sexual and reproductive health. Quality of data collected was examined by looking at how the survey was administered, including identifying two sources of errors that typically threaten data quality11 This study assumes that bias does not change with sample size. In order to increase the sample size, the data collection period was extended, leaving everything else unchanged. It is, therefore, assumed that the decreasing effects of the learning curve are negligible.: (i errors at the individual level with regards to survey methodology performance and cognitive difficulties [measured with the Response Consistency Index (RCI]; and (ii errors at the aggregate level (how desirability bias, interviewer gender, and interview privacy settings affect responses. Results: No statistically significant differences in participant non-response rates were found at the individual level across all survey interview methods. At the individual question level, self-completion methods generated higher non-response and error rates than assisted methods. The SAI method showed the poorest performance of all four methods in terms of non-response rate (1.6%22 Percentage of data with non-response values at the question level. and RCI (83.0%.At the aggregate level, the prevalence of several key risk indicators was statistically significant between methods.

2008-01-01

Full Text Available Forty-eight children (M age = 4.8 years infected with HIV/AIDS and living in the Dominican Republic were randomly assigned to a massage therapy or a play session control group. The children in the massage therapy group received two weekly 20-min massages for 12 weeks; the children in the control group participated in a play session (coloring, playing with blocks for the same duration and length as the massage therapy group. Overall, the children in the massage therapy group improved in self-help abilities and communication, suggesting that massage therapy may enhance daily functioning for children with HIV/AIDS. Moreover, the HIV infected children who were six or older also showed a decrease in internalizing behaviors; specifically depressive/anxious behaviors and negative thoughts were reduced. Additionally, baseline assessments revealed IQ equivalence below normal functioning for 70% of the HIV infected children and very high incidences of mood problems (depression, withdrawn for 40% of the children and anxiety problems for 20% of the children, suggesting the need for better monitoring and alternative interventions in countries with limited resources to improve cognition and the mental health status of children infected with HIV/AIDS.

Thêmis R. Silveira

1999-12-01

Full Text Available The seroprevalence of hepatitis B was investigated in over 12 000 subjects in six countries of Latin America: Argentina, Brazil, Chile, the Dominican Republic, Mexico, and Venezuela. Each study population was stratified according to age, gender, and socioeconomic status. Antibodies against hepatitis B core antigen (anti-HBc were measured in order to determine hepatitis B infection. The highest overall seroprevalence was found in the Dominican Republic (21.4%, followed by Brazil (7.9%, Venezuela (3.2%, Argentina (2.1%, Mexico (1.4%, and Chile (0.6%. In all the countries an increase in seroprevalence was found among persons 16 years old and older, suggesting sexual transmission as the major route of infection. In addition, comparatively high seroprevalence levels were seen at an early age in the Dominican Republic and Brazil, implicating a vertical route of transmission.

Calzada, Esther; Barajas-Gonzalez, R Gabriela; Huang, Keng-Yen; Brotman, Laurie

2017-01-01

This study examined mother- and teacher-rated internalizing behaviors (i.e., anxiety, depression, and somatization symptoms) among young children using longitudinal data from a community sample of 661 Mexican and Dominican families and tested a conceptual model in which parenting (mother's socialization messages and parenting practices) predicted child internalizing problems 12 months later. Children evidenced elevated levels of mother-rated anxiety at both time points. Findings also supported the validity of the proposed parenting model for both Mexican and Dominican families. Although there were different pathways to child anxiety, depression, and somatization among Mexican and Dominican children, socialization messages and authoritarian parenting were positively associated with internalizing symptoms for both groups.

This paper discusses the occurrence and spatial distribution of metals and persistent organic pollutants (POPs: including organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), Polybrominated diphenyl ethers (PBDEs), and polycyclic aromatic hydrocarbons (PAHs) in sediments from a river-reservoir system. Surface sediments were sampled from thirteen sites of the Congo River Basin and Lake Ma Vallée, both situated in the vicinity of the capital city Kinshasa (Congo Democratic Republic). Sediment qualities were evaluated using toxicity test based on exposing Ostracods to the sediment samples. The highest metal concentrations were observed in sediments subjected to anthropogenic influences, urban runoff and domestic and industrial wastewaters, discharge into the Congo River basin. Ostracods exposed to the sediments resulted in 100% mortality rates after 6d of incubation, indicating the ultimate toxicity of these sediments as well as potential environmental risks. The POPs and PAHs levels in all sediment samples were low, with maximum concentration found in the sediments (area of pool Malebo): OCP value ranged from 0.02 to 2.50 with ∑OCPs: 3.3μgkg(-1); PCB ranged from 0.07 to 0.99 with Total PCBs (∑7×4.3): 15.31μgkg(-1); PAH value ranged from 0.12 to 9.39 with ∑PAHs: 63.89μgkg(-1). Our results indicate that the deterioration of urban river-reservoir water quality result mainly from urban stormwater runoff, untreated industrial effluents which discharge into the river-reservoirs, human activities and uncontrolled urbanization. This study represents useful tools incorporated to evaluate sediment quality in river-reservoir systems which can be applied to similar aquatic environments. Copyright © 2014 Elsevier Ltd.

2015-08-01

Full Text Available The globalization of the world economy has opened up new possibilities for cross-border labor organizing. In fact, several U.S. unions are working together with unions from Mexico, Honduras, Guatemala, the Dominican Republic, Japan, South Korea, and many European nations. For example, over the last several years, UNITE (Union of Needletrades, Industrial, and Textile Employees, the AFL-CIO, and the international garment workers trade secretariat have worked directly with maquiladora workers in Honduras and the Dominican Republic. These efforts led to the formation of several labor unions and the first contracts ever negotiated in the maquiladoras in the Dominican Republic. In addition, labor rights and solidarity organizations, like the Campaign for Labor Rights, Witness for Peace, and the US/Guatemala Labor Education Project (US/GLEP, along with many other groups, have also played key roles in the formation of maquiladora unions in Nicaragua and Guatemala.

Full Text Available Female sex workers (FSW are often the focus of primary HIV prevention efforts. However, little attention has been paid to the prevention, treatment, and care needs of FSW living with HIV. Based on formative research, we developed an integrated model to promote prevention and care for FSW living with HIV in Santo Domingo, Dominican Republic, including (1 individual counseling and education; (2 peer navigation; (3 clinical provider training; and (4 community mobilization. We enrolled 268 FSW living with HIV into the intervention and conducted socio-behavioral surveys, sexually transmitted infection (STI testing, and viral load (VL assessments. We used multivariate logistic regression to identify behavioral and socio-demographic factors associated with detectable VL (>50 copies/mL and STI prevalence. Over half of all participants (51.9% had a detectable VL, even though most received HIV-related care in the last 6 months (85.1% and were currently on anti-retroviral treatment (ART (72.4%. Factors positively associated with a detectable VL included being 18-35 years of age (Adjusted Odds Ratio [AOR] 2.46, 95% CI 1.31-4.60, having ever used drugs (AOR 2.34, 95% CI 1.14-4.79, and having ever interrupted ART (AOR 3.09, 95% CI 1.44-6.59. Factors protective against having a detectable VL included being single (AOR 0.45, 95% 0.20-0.98 and being currently on ART (AOR 0.17, 95% CI 0.07-0.41. Nearly one-quarter (23.1% had an STI, which was associated with being single (AOR 3.21, 95% CI 1.27-8.11 and using drugs in the last 6 months (AOR 3.54, 95% CI 1.32-9.45. Being on ART was protective against STI (AOR 0.51, 95% CI 0.26-1.00. Baseline findings indicate significant barriers to VL suppression and STI prevention among FSW living with HIV and highlight gaps in the continuum of HIV care and treatment. These findings have important implications for both the individual health of FSW and population-level HIV transmission dynamics.

Objectives The objectives of this study were to estimate the point prevalence of sexually transmitted infection (STI) and to investigate the sexual practices and behaviours associated with STIs in a group of gay men, other men who have sex with men and transgender women (GMT) in the province of La Romana, Dominican Republic. Design A cross-sectional study of a convenience sample of GMT persons. Setting The study was conducted in the province of La Romana, Dominican Republic, in June–July 2013. Participants Out of 117 GMT persons screened, a total of 100 completed the study. Participants had to be at least 18 years of age, reside in La Romana and have had sex with another man in the preceding 12 months. All participants were interviewed and tested for STI. Primary outcome measure The main outcome of interest was the detection of any STI (HIV, herpes simplex virus type 2 (HSV-2), syphilis, hepatitis B or C) by serology. Results Among 100 participants, the median age was 22 years (range 18–65). One-third had consumed illicit drugs the preceding year and only 43% consistently used condoms. Prevalence was 38% for HSV-2, 5% for HIV and 13% for syphilis. There were no cases of hepatitis B or C. Factors associated with the odds of a STI were age >22 years (OR=11.1, 95% CI 3.6 to 34.5), receptive anal intercourse (OR=4.2, 95% CI 1.3 to 13.6) and having ≥2 male sexual partners during the preceding month (OR=4, 95% CI 1.3 to 12.5). Conclusions In this group of GMT persons, seroprevalence of STI was high, and a number of risk behaviours were associated with STI. These preliminary data will help inform policy and programmes to prevent HIV/STI in GMT persons in the region. PMID:25926151

The Republic of Macedonia is situated in the central part of the Balcan Peninsula and covers a surface of 25. 713 km 2 Its territory is found in one of the most significant geothermal zones in this part of Balkans. The earths crust in this region suffers poli phase structural deformations, which as a result gives different structural features. The geothermal explorations in the Republic of Macedonia intensively started to conduct after 1970, after the first effects of the energy crisis. As a result of these explorations, more than 50 springs of mineral and thermo mineral waters with a total yield of more than 1.400 I./sec. And proved exploitation reservoirs of more than 1.000 I./sec. with temperatures higher than the medium year seasons hesitations for this part of the Earth in the boundaries of 20-75 o C with significant quantities of geothermal energy. This paper will shortly present the available geothermal resources and classification, according the type of geothermal energy, hydro geothermal, lithogeothermal and according the way of transport of the geothermal energy, convective and conductive systems. The next will present short descriptions of the resources, the degree of exploitation and the prognosis dimensions of the reservoirs. (Original)

Calculation and analysis of the non-point source pollution in the upstream watershed of the Panjiakou Reservoir, People's Republic of China

Zhang, S.; Tang, L.

2007-05-01

Panjiakou Reservoir is an important drinking water resource in Haihe River Basin, Hebei Province, People's Republic of China. The upstream watershed area is about 35,000 square kilometers. Recently, the water pollution in the reservoir is becoming more serious owing to the non-point pollution as well as point source pollution on the upstream watershed. To effectively manage the reservoir and watershed and develop a plan to reduce pollutant loads, the loading of non-point and point pollution and their distribution on the upstream watershed must be understood fully. The SWAT model is used to simulate the production and transportation of the non-point source pollutants in the upstream watershed of the Panjiakou Reservoir. The loadings of non-point source pollutants are calculated for different hydrologic years and the spatial and temporal characteristics of non-point source pollution are studied. The stream network and topographic characteristics of the stream network and sub-basins are all derived from the DEM by ArcGIS software. The soil and land use data are reclassified and the soil physical properties database file is created for the model. The SWAT model was calibrated with observed data of several hydrologic monitoring stations in the study area. The results of the calibration show that the model performs fairly well. Then the calibrated model was used to calculate the loadings of non-point source pollutants for a wet year, a normal year and a dry year respectively. The time and space distribution of flow, sediment and non-point source pollution were analyzed depending on the simulated results. The comparison of different hydrologic years on calculation results is dramatic. The loading of non-point source pollution in the wet year is relatively larger but smaller in the dry year since the non-point source pollutants are mainly transported through the runoff. The pollution loading within a year is mainly produced in the flood season. Because SWAT is a

Full Text Available Este artículo responde a la necesidad de explorar cómo el acto de equilibrio del estado Dominicano, sujeto a la demanda económica de mano de obra inmigrante, por un lado, y a la presión política que exige la exclusión de los haitianos de la sociedad dominicana, por el otro, es negociado localmente. Con base en investigación etnográfica en comunidades bananeras llamadas bateyes, este artículo presenta un análisis de las respuestas locales a los cambios causados por la llegada de un creciente número de inmigrantes haitianos. Aun cuando los inmigrantes haitianos son considerados necesarios para la producción bananera, el coexistir con ellos genera incertidumbres sobre violencia e identidad entre los dominicanos. Este artículo argumenta que los residentes dominicanos hacen frente a estos sentimientos de incertidumbre mediante la cultivación de una aparente superioridad moral sobre sus vecinos haitianos. Finalmente, este artículo sugiere que las prácticas de los dominicanos, quienes luchan por ganarse la vida a la par de sus vecinos haitianos, revelan una relación complicada no sólo por la existencia de una ideología anti-haitiana, pero por una vida precaria, históricamente construida, que marginaliza a los residentes de los bateyes en su conjunto.

Based on ethnographic research conducted in banana-growing communities called 'bateyes', this article provides an analysis of local responses to changes occurring with the arrival of increasingly more Haitian residents. While Haitian migrants are regarded as necessary for banana production, living among them triggers insecurities about violence and identity among Dominicans.

Full Text Available This article studies horizontal accountability in the Dominican Republic. First it analyses the rules regulating the system of checks and balances. Although important, institutional rules cannot explain the variation in the levels of accountability across time found in the Dominican case. Therefore, the article focuses on the execution of national budgets and the financial situation of the accountability institutions. The article suggests using an index of budgetary disproportionality based on a comparison of the congressionally approved budget and the executed budget to measure the level of horizontal accountability. A multivariate time-series regression analysis shows that budgetary disproportionality increases with presidential dominance. The article concludes that for the period 1967-2009, it is presidential behaviour more than any other factor that has prevented an effective system of checks and balances. Therefore the case confirms O’Donnell’s hypothesis of Delegative Democracies.Este artículo estudia la rendición de cuentas horizontal en República Dominicana. Primero se estudian las normas constitucionales que regulan el sistema de pesos y contrapesos. Aunque importantes, estas no explican la gran variación en niveles de rendición de cuentas observada en el caso dominicano. Por lo tanto, el trabajo se enfoca en el ejercicio de los gastos de los presupuestos nacionales y la situación financiera de las instituciones de control. El artículo sugiere analizar la situación presupuestaria de las instituciones fiscalizadoras y propone utilizar la desproporcionalidad entre el presupuesto aprobado y el ejecutado como un indicador del nivel de rendición de cuentas en un país. Un análisis multivariado de regresión de series de tiempo demuestra que la desproporcionalidad presupuestal aumenta con la preponderancia presidencial. Se concluye que, para el caso dominicano en el período 1967-2009, el comportamiento de varios presidentes m

Analogia ad legendum. Semantic, practical and compositional function of two pulpits in the Dominican church in Lublin

Directory of Open Access Journals (Sweden)

Paulina Kluz

2016-12-01

Full Text Available The Dominican church in Lublin contains an unusual example of two pulpits in a sacred interior, which are situated vis-à-vis at the rood arch. They were sculpted by Sebastian Zeisl, who, with the aid of his workshop, made the rococo furnishing of the church in the years 1756–1761. The sculptural decoration of the pulpits makes references to their preaching function, as well as to Dominican spirituality. The solution formally seems to have been inspired by the compositional model of two pulpits on either side of the altar, an elaboration of the symmetrical (stage-like organization of the sacred interior. The fact that the contractor was familiar with such layout could stem from the impact exerted by local inspiration (e.g. St. Anne’s church in Lubartów or the artist’s earlier Central European experience, probably including his education among Viennese artists. However, the construction of two Dominican pulpits, both of which were used (none of them is apparent may indicate that their roles could go beyond merely compositional ones. It seems that their emergence was influenced by individual needs of the Lublin Dominican monastery, especially their preaching practices. The knowledge gained so far allows us to suspect that the construction of the two pulpits is related to their role in the liturgy, namely the polemical sermons practised by the Order of Preachers in Lublin.

Full Text Available Main objective of the essay under consideration was investigation and characterized most important source materials stocked at the Archive of the Cracow’s Dominican Province to present the history of their studium generale during the Modern period. Also, the current knowledge of a.m. period of studium generale was screened- out and some searching hypothesis were proposed concerning the history of the Cracow’s Dominican studium generale. The searching time frame have been limited to XVI up to XVII century. Taken into consideration, the current status of research works performed so far, one ought to stated that the Modern Epoch has not been searched out with the same consciousness compare to the Medieval one. As the most important printed source materials, one ought to account the documents issued by the general and provincial chapters of the Convent. The documents of the provincial chapters have been listed and screened by Father Fabian Madura, and were stocked as the typescript formats at the Cracow’s Dominican Convent Library. Based on the searched source materials of General Chapter of Dominican Convent at Cracow, it is possible to present the general overview of the convent education system and its changes in due time. Due to the records found it would be possible to identify – position and name – the Dominicans nominated to the Convent stadium generale. The most important manuscript stocked at the Cracow’s Dominican Convent Archive as the education system is concern, is so called Liber Studii Generalis cracoviensis (rkps 20. This manuscript covers the list of friars who have been nominated to work at stadium generale. A.m. document has to verify and compare with other sources.

Taxonomic Revision of Hispaniola Tiger Beetles in the Genus Brasiella Rivalier, 1954 (Coleoptera, Carabidae, Cicindelinae

Directory of Open Access Journals (Sweden)

Robert Acciavatti

2011-11-01

Full Text Available The Brasiella tiger beetle fauna on Hispaniola, the second largest island of the Greater Antilles, has more species diversity than currently recognized as all populations previously have been assigned to the insular endemic Brasiella dominicana (Mandl. A comparative study of adult morphology, particularly male genitalic and female abdominal characters, for available Brasiella specimens from populations on Hispaniola, proposes eight additional new species also endemic to this island. Except for three sympatric species in the Sierra de Baoruco in southern Dominican Republic occurring in different habitats, all the Brasiella on Hispaniola appear to be allopatric. Most species occur in the major mountainous regions of Hispaniola. Two species, however, are known only from river floodplains in the southern coastal plain of the Dominican Republic. Brasiella dominicana (Mandl and B. ocoa, new species, occur along river floodplains emanating from the eastern end of the Cordillera Central in the Dominican Republic. Two new Brasiella species, B. bellorum, and B. philipi, occur in the Cordillera Central, Dominican Republic, the former species from central portions, and the latter species from north slopes of this mountain range, respectively. Three new Brasiella species, B. rawlinsi, B. iviei, and B. youngi, are isolated in the Sierra de Baoruco, Dominican Republic, where each occupies a different habitat along an altitudinal gradient. The two new Brasiella species in Haiti are B. darlingtoniana, in the Massif de la Selle, and B. davidsoni, in the Massif de la Hotte. All nine Brasiella species on Hispaniola, along with B. viridicollis (Dejean and its two subspecies on Cuba, belong to the viridicollis species group of the genus Brasiella based on criteria presented in earlier published phylogenetic studies of Brazilian and West Indian tiger beetles. The subspecies Brasiella viridicollis fernandozayasi (Kippenhan, Ivie & Hopp may represent a distinct species

Response of littoral macrophytes to water level fluctuations in a storage reservoir

Krolová M.

2013-05-01

Full Text Available Lakes and reservoirs that are used for water supply and/or flow regulations have usually poorly developed littoral macrophyte communities, which impairs ecological potential in terms of the EU Water Framework Directive. The aim of our study was to reveal controlling factors for the growth of littoral macrophytes in a storage reservoir with fluctuating water level (Lipno Reservoir, Czech Republic. Macrophytes occurred in this reservoir only in the eulittoral zone i.e., the shoreline region between the highest and the lowest seasonal water levels. Three eulittoral sub-zones could be distinguished: the upper eulittoral with a stable community of perennial species with high cover, the middle eulittoral with relatively high richness of emergent and amphibious species present at low cover values, and the lower eulittoral devoid of permanent vegetation. Cover and species composition in particular sub-zones were primarily influenced by the duration and timing of flooding, followed by nutrient limitation and strongly reducing conditions in the flooded organic sediment. Our results stress the ecological importance of eulittoral zone in reservoirs with fluctuating water levels where macrophyte growth can be supported by targeted management of water level, thus helping reservoir managers in improving the ecological potential of this type of water bodies.

This study was conducted to assess potential human health risks presented by pathogenic bacteria in a protected multi-use lake-reservoir (Lake Ma Vallée) located in west of Kinshasa, Democratic Republic of Congo (DRC). Water and surface sediments from several points of the Lake were collected during summer. Microbial analysis was performed for Escherichia coli, Enterococcus (ENT), Pseudomonas species and heterotrophic plate counts. PCR amplification was performed for the confirmation of E. coli, ENT, Pseudomonas spp. and Pseudomonas aeruginosa isolated from samples. The results reveal low concentration of bacteria in water column of the lake, the bacterial quantification results observed in this study for the water column were below the recommended limits, according to WHO and the European Directive 2006/7/CE, for bathing water. However, high concentration of bacteria was observed in the sediment samples; the values of 2.65 × 10(3), 6.35 × 10(3), 3.27 × 10(3) and 3.60 × 10(8) CFU g(-1) of dry sediment for E. coli, ENT, Pseudomonas spp. and heterotrophic plate counts, respectively. The results of this study indicate that sediments of the Lake Ma Vallée can constitute a reservoir of pathogenic microorganisms which can persist in the lake. Possible resuspension of faecal indicator bacteria and pathogens would affect water quality and may increase health risks to the population during recreational activities. Our results indicate that the microbial sediment analysis provides complementary and important information for assessing sanitary quality of surface water under tropical conditions.

Globalization and loss of plant knowledge: challenging the paradigm.

Science.gov (United States)

Vandebroek, Ina; Balick, Michael J

2012-01-01

The erosion of cultural knowledge and traditions as a result of globalization and migration is a commonly reported phenomenon. We compared one type of cultural knowledge about medicinal plants (number of plants reported to treat thirty common health conditions) among Dominican laypersons who self-medicate with plants and live in rural or urban areas of the Dominican Republic (DR), and those who have moved to New York City (NYC). Many plants used as medicines were popular Dominican food plants. These plants were reported significantly more often by Dominicans living in NYC as compared to the DR, and this knowledge was not age-dependent. These results contradict the popular paradigm about loss of cultural plant knowledge and is the first study to report a statistically measurable increase in this type of knowledge associated with migration.

Qualitative needs assessment of HIV services among Dominican, Mexican and Central American immigrant populations living in the New York City area.

Shedlin, M G; Shulman, L

2004-05-01

This paper reports on research designed to assess access to care by Latino immigrant populations in the New York area. A qualitative approach and methods were employed, involving focus groups with PLWAs (persons living with AIDS) and affected men and women from Mexico, the Dominican Republic and Central America to explore the perceptions, beliefs, experiences and knowledge of HIV care issues. A total of 57 men and women participated, ranging in age from 19-61. Results included detailed information on cultural meanings of HIV/AIDS; experience of stigma and rejection; gendered health-seeking behaviour; testing issues; and satisfaction with services. Data support the conclusion that to be effective in reaching and providing services to these immigrant groups, it is crucial to understand the environment from which they come and the impact of immigration. Poverty, repressive governments, lack of education/literacy, ethnicity, class, colour-based stigma and cultural norms are crucial factors in determining their attitudes, motivations, decisions and behaviour. AIDS agencies were seen to play a crucial role in connecting PLWAs to services and resources. The key elements for the provision of services to this population appear to be those that build on cultural norms and network human and institutional resources.

Role of a Semiotics-Based Curriculum in Empathy Enhancement: A Longitudinal Study in Three Dominican Medical Schools.

Science.gov (United States)

San-Martín, Montserrat; Delgado-Bolton, Roberto; Vivanco, Luis

2017-01-01

Background: Empathy in the context of patient care is defined as a predominantly cognitive attribute that involves an understanding of the patient's experiences, concerns, and perspectives, combined with a capacity to communicate this understanding and an intention to help. In medical education, it is recognized that empathy can be improved by interventional approaches. In this sense, a semiotic-based curriculum could be an important didactic tool for improving medical empathy. The main purpose of this study was to determine if in medical schools where a semiotic-based curriculum is offered, the empathetic orientation of medical students improves as a consequence of the acquisition and development of students' communication skills that are required in clinician-patient encounters. Design: This quasi-experimental study was conducted in three medical schools of the Dominican Republic that offer three different medical curricula: (i) a theoretical and practical semiotic-based curriculum; (ii) a theoretical semiotic-based curriculum; and (iii) a curriculum without semiotic courses. The Jefferson scale of empathy was administered in two different moments to students enrolled in pre-clinical cycles of those institutions. Data was subjected to comparative statistical analysis and logistic regression analysis. Results: The study included 165 students (55 male and 110 female). Comparison analysis showed statistically significant differences in the development of empathy among groups ( p semiotic-based curriculum contributed toward the enhancement of empathy. Conclusion: These findings demonstrate the importance of medical semiotics as a didactic teaching method for improving beginners' empathetic orientation in patients' care.

Reservoir performance and characterization are vital parameters during the development phase of a project. Infill drilling of wells on a uniform spacing, without regard to characterization does not optimize development because it fails to account for the complex nature of reservoir heterogeneities present in many low permeability reservoirs, especially carbonate reservoirs. These reservoirs are typically characterized by: (1) large, discontinuous pay intervals; (2) vertical and lateral changes in reservoir properties; (3) low reservoir energy; (4) high residual oil saturation; and (5) low recovery efficiency. The operational problems they encounter in these types of reservoirs include: (1) poor or inadequate completions and stimulations; (2) early water breakthrough; (3) poor reservoir sweep efficiency in contacting oil throughout the reservoir as well as in the nearby well regions; (4) channeling of injected fluids due to preferential fracturing caused by excessive injection rates; and (5) limited data availability and poor data quality. Infill drilling operations only need target areas of the reservoir which will be economically successful. If the most productive areas of a reservoir can be accurately identified by combining the results of geological, petrophysical, reservoir performance, and pressure transient analyses, then this ''integrated'' approach can be used to optimize reservoir performance during secondary and tertiary recovery operations without resorting to ''blanket'' infill drilling methods. New and emerging technologies such as geostatistical modeling, rock typing, and rigorous decline type curve analysis can be used to quantify reservoir quality and the degree of interwell communication. These results can then be used to develop a 3-D simulation model for prediction of infill locations.

Full Text Available From June to November 1793 Grodno (now Belarus was the place of the last session of Parliament of the Polish-Lithuanian Commonwealth, with the participation of king Stanisław August Poniatowski, and it was where the second partition of Poland was approved. In the days free of parliamentary debates, Grodno’s Dominicans prepared a series of physics experiments for the king. The course of the experiments and their subject matter is known from a press release (Pismo Peryodyczne Korrespondenta 2, January 9, 1794, pp. 35–42. It is a type of daily report informing about 18 meetings, each time indicating their subject matter. This report was sufficient to recreate the course and the type of the experiments. Three thematic groups presented by the Dominicans can be distinguished. The first is a presentation of the physics cabinet – the king was visited, among others, the Nooth’s apparatus to produce “carbonated water”, a geological collection and other items used in the later shows. The second series of demonstrations was devoted to issues related to electricity. The idea and nature of lightning was also demonstrated. The third series of presentations concerned the properties of gases. In addition to other demonstrations, the Dominicans prepared an experiment which presented the process of producing water from oxygen and hydrogen. The experiment lasted all day, during which the reagents were measured: the volume of gases that were used and the mass of the water obtained. The report brings a lot of important information, indicating the level of scientific knowledge and the experimental skills of the Dominicans. It is evidence of how modern physics was taught by the Dominicans with the use of appropriate instruments for this purpose. It is also a source of knowledge about school equipment in Poland. Additionally, the report is so far one of the few well-documented public demonstrations prepared for the king. It also confirms the view that the

optimization algorithm into the state transition that lowers the starting problem dimension and alleviates the curse of dimensionality. The algorithms can solve multi-objective optimization problems, without significantly increasing the complexity and the computational expenses. The algorithms can handle dense and irregular variable discretization, and are coded in Java as prototype applications. The three algorithms were tested at the multipurpose reservoir Knezevo of the Zletovica hydro-system located in the Republic of Macedonia, with eight objectives, including urban water supply, agriculture, ensuring ecological flow, and generation of hydropower. Because the Zletovica hydro-system is relatively complex, the novel algorithms were pushed to their limits, demonstrating their capabilities and limitations. The nSDP and nRL derived/learned the optimal reservoir policy using 45 (1951-1995) years historical data. The nSDP and nRL optimal reservoir policy was tested on 10 (1995-2005) years historical data, and compared with nDP optimal reservoir operation in the same period. The nested algorithms and optimal reservoir operation results are analysed and explained.

Full Text Available The study reported here explored the influence of maternal, health care, pregnancy, and child-related factors upon the duration of total breast-feeding (DTBF in the Dominican Republic. The data for the study, which included 1984 mother-child pairs representative of the Dominican population, came from the National Health Survey of 1991. The child in each of the mother-child pairs was the mother's last-born child who had been breast-fed and was less than 3 years of age at the time of the survey. Interviews with the mothers were used to collect information about the duration of breast-feeding and the factors studied (including maternal age, urban/rural residence, parity, mother's socioeconomic status, maternal education, maternal employment, mother's desire for pregnancy, type of delivery, place of delivery, the type of health worker attending the delivery, the child's sex, the child's birth weight, the time elapsed between delivery and initiation of breast-feeding, the child's age at complete weaning, and the child's age at the time of the survey. The child's risk of complete weaning at different ages was calculated using the life table method, and the independent effect of each of the study variables was estimated using Cox's regression model. The median DTBF was 7 months. The risk that a child would be completely weaned (the relative rate of complete weaning, or RRCW was found to be higher among children who received foods other than breast milk and water while still breast-feeding (RRCW = 8.56; 95% CI = 4.25-17.20, whose mothers had some university education (RRCW = 1.48; 95% CI = 1.24-1.77, who began breast-feeding a day or more after delivery (RRCW = 1.25; 95% CI = 1.11-1.40, who were born in either public health institutions (RRCW = 1.62; 95% CI = 1.24-2.11 or private health institutions (RRCW = 2.19; 95% CI = 1.65-2.91, and who were the first-born of mothers with low socioeconomic status (RRCW = 1.80; 95% CI = 1.45-2.24.

Water management of Republic of Macedonia

International Nuclear Information System (INIS)

1999-01-01

The Republic of Macedonia is one of the countries that do not have sufficient water resources, and their shortage has been already felt during certain periods. The problem already mentioned as global: uneven distribution in time, space and quality are the main characteristics of the water resources. The water management a branch of the economy dealing with management, utilization, protection and planning of the water resources is considered a key implementation of all strategic plans for development of one country. The basic goal of the water management is to fully utilize the water resources in order to reach the most effective and most economic resolution of problems related to the water resources. The problem of pollution and wastage of water, which is more acute at times of intensive technological development of the society, is rapidly depleting supplies water and makes us seriously thinking no just our own survival, but also that of future generations. The concept of sustainable development means future planning for utilizing and protecting water resources bearing in mind not only the generations to come. In the book available water resources in Republic of Macedonia, current condition of the existing water management facilities - dams and reservoirs, as well as irrigation systems are presented. Also, the book deals with the water quality condition and activities for ecological water protection, including relevant measures for protection of catchment areas and the soil from erosion. In addition projects under construction are given. Namely, in the Republic of Macedonia two high dams and a small hydro system are under construction, as well as rehabilitation of three large irrigation schemes

A reservoir's life begins with exploration leading to discovery followed by delineation of the reservoir, development of the field, production by primary, secondary and tertiary means, and finally to abandonment. Sound reservoir management is the key to maximizing economic operation of the reservoir throughout its entire life. Technological advances and rapidly increasing computer power are providing tools to better manage reservoirs and are increasing the gap between good and neural reservoir management. The modern reservoir management process involves goal setting, planning, implementing, monitoring, evaluating, and revising plans. Setting a reservoir management strategy requires knowledge of the reservoir, availability of technology, and knowledge of the business, political, and environmental climate. Formulating a comprehensive management plan involves depletion and development strategies, data acquisition and analyses, geological and numerical model studies, production and reserves forecasts, facilities requirements, economic optimization, and management approval. This paper provides management, engineers, geologists, geophysicists, and field operations staff with a better understanding of the practical approach to reservoir management using a multidisciplinary, integrated team approach

Formulating a comprehensive management plan involves depletion and development strategies, data acquisition and analyses, geological and numerical model studies, production and reserves forecasts, facilities requirements, economic optimization, and management approval. This paper provides management, engineers geologists, geophysicists, and field operations staff with a better understanding of the practical approach to reservoir management using a multidisciplinary, integrated team approach

Musculoskeletal disorders are the second leading cause of years lived with disability globally. Total knee replacement (TKR) offers patients with advanced arthritis relief from pain and the opportunity to return to physical activity. We investigated the impact of TKR on physical activity for patients in a developing nation. As part of the Operation Walk Boston surgical mission program, we interviewed 18 Dominican patients (78% women) who received TKR about their level of physical activity after surgery. Qualitative interviews were conducted in Spanish, and English transcripts were analyzed using content analysis. Most patients found that TKR increased their participation in physical activities in several life domains, such as occupational or social pursuits. Some patients limited their own physical activities due to uncertainty about medically appropriate levels of joint use and postoperative physical activity. Many patients noted positive effects of TKR on mood and mental health. For most patients in the study, religion offered a framework for understanding their receipt of and experience with TKR. Our findings underscore the potential of TKR to permit patients in the developing world to return to physical activities. This research also demonstrates the influence of patients' education, culture, and religion on patients' return to physical activity. As the global burden of musculoskeletal disease increases, it is important to characterize the impact of activity limitation on patients' lives in diverse settings and the potential for surgical intervention to ease the burden of chronic arthritis.

Quantitative physical and chemical variables used to assess erosion and fertility loss in tropical Dominican and Haitian soils

Science.gov (United States)

Pastor, J.; Alexis, S.; Vizcayno, C.; Hernández, A. J.

2009-04-01

The Pedernales province (Dominican Republic) has the main part of the only Biosphere Reserve in that Caribbean Island, including the Bahoruco and Jaragua National Parks. In these Parks is possible to find almost the totality of tropical forest ecosystems (evergreen rain forest, latifoliated forest, dry forest and mangrove forest on mainland), as well as the most frequent soil uses in the Dominican country. The consulted bibliography about the soils is very scarce and it does not give any information relating to this natural resource, which is basic for a sustainable development management in this territory. When Christopher Columbus reached the island, its plant cover constituted 95% of the land. This was largely because the limited, rudimentary tools used by the Indians to exploit the soil, allowed them to maintain a well-balanced ecological system. The initial type of agriculture practised by the indigenous inhabitants was scarcely destructive and based on vegetatively reproducing crops propagated through cuttings, but later forest burning was an especially significant management practice aimed at releasing nutrients into the soil, in an environment in which under natural conditions, particularly those of the rainforest, these were mostly locked within plant structures. The colonial system, on the contrary, brought with it more elaborate methods and utensils enabling them to cultivate cereals (somewhat unknown to the native Indians) and to rear livestock (cows, goats) yet contributed to the growth of deforestation. Agricultural activities were not confined to the plains; even the virgin woods of the mountains were exploited. The monocrops grown across vast expanses rapidly rid the soil of its productive capacity. Cutting down and burning forest for agricultural uses, and also industrial exploitation of bauxite and limestone produced also important alterations in the soil processes. Agricultural activities were not confined to the plains; even the virgin woods of

Post flooding damage assessment of earth dams and historical reservoirs using non-invasive geophysical techniques

Science.gov (United States)

Sentenac, Philippe; Benes, Vojtech; Budinsky, Vladimir; Keenan, Helen; Baron, Ron

2017-11-01

This paper describes the use of four geophysical techniques to map the structural integrity of historical earth reservoir embankments which are susceptible to natural decay with time. The four techniques that were used to assess the post flood damage were 1. A fast scanning technique using a dipole electromagnetic profile apparatus (GEM2), 2. Electrical Resistivity Tomography (ERT) in order to obtain a high resolution image of the shape of the damaged/seepage zone, 3. Self-Potential surveys were carried out to relate the detected seepage evolution and change of the water displacement inside the embankment, 4. The washed zone in the areas with piping was characterised with microgravimetry. The four geophysical techniques used were evaluated against the case studies of two reservoirs in South Bohemia, Czech Republic. A risk approach based on the Geophysical results was undertaken for the reservoir embankments. The four techniques together enabled a comprehensive non-invasive assessment whereby remedial action could be recommended where required. Conclusions were also drawn on the efficiency of the techniques to be applied for embankments with wood structures.

Man-made reservoirs are common across the world and provide a wide range of ecological services. Environmental conditions in riverine reservoirs are affected by the changing climate, catchment-wide processes and manipulations with the water level, and water abstraction from the reservoir. Long-term trends of environmental conditions in reservoirs thus reflect a wider range of drivers in comparison to lakes, which makes the understanding of reservoir dynamics more challenging. We analysed a 32-year time series of 36 environmental variables characterising weather, land use in the catchment, reservoir hydrochemistry, hydrology and light availability in the small, canyon-shaped Římov Reservoir in the Czech Republic to detect underlying trends, trend reversals and regime shifts. To do so, we fitted linear and piecewise linear regression and a regime shift model to the time series of mean annual values of each variable and to principal components produced by Principal Component Analysis. Models were weighted and ranked using Akaike information criterion and the model selection approach. Most environmental variables exhibited temporal changes that included time-varying trends and trend reversals. For instance, dissolved organic carbon showed a linear increasing trend while nitrate concentration or conductivity exemplified trend reversal. All trend reversals and cessations of temporal trends in reservoir hydrochemistry (except total phosphorus concentrations) occurred in the late 1980s and during 1990s as a consequence of dramatic socioeconomic changes. After a series of heavy rains in the late 1990s, an administrative decision to increase the flood-retention volume of the reservoir resulted in a significant regime shift in reservoir hydraulic conditions in 1999. Our analyses also highlight the utility of the model selection framework, based on relatively simple extensions of linear regression, to describe temporal trends in reservoir characteristics. This approach can

How discrimination and stress affects self-esteem among Dominican immigrant women: an exploratory study.

Science.gov (United States)

Panchanadeswaran, Subadra; Dawson, Beverly Araujo

2011-01-01

Understanding the factors that contribute to the health disparities among racial and ethnic minorities in the United States is very important given the growing Latina population. Although researchers have investigated the health and mental health status among Latinas, the relationship between mental health and self-esteem has not been given a lot of attention. Given that self-esteem is a proxy for mental health status, investigations exploring the factors that can negatively affect self-esteem are needed. Therefore, the current study examined the influence of discrimination and stress on self-esteem among Dominican immigrant women. A cross-sectional study was undertaken among 235 immigrant Dominican women in New York City. Women (age 18-49 years) and in the United States for fewer than 20 years were more likely to report experiencing discrimination compared to women older than age 50 years and in the United States for more than 20 years. After controlling for age, time in the United States, educational level, and income, high levels of discrimination (-0.09, p < 0.01) and stress (-0.69, p < 0.001) were significantly associated with reduced self-esteem. Interventions with Latino/a populations, especially women, need to acknowledge their individual evaluations of the discriminatory and stressful experiences that negatively influence their self-esteem and subsequently their mental health status.

“Neither Here Nor There.” The Experience of Borderless Nation in Contemporary Dominican-American Literature

Directory of Open Access Journals (Sweden)

2017-11-01

Full Text Available “Neither Here Nor There.” The Experience of Borderless Nation in Contemporary Dominican-American Literature Discussing migrant identities, critics very often focus on the state in-between, the state between the borders, or being neither here nor there, and a migrant group that seems to epitomize this in-between condition is the Dominican-Americans. Consequently, the article seeks to examine the experience of in-betweenness, of being suspended between the boundaries and borders of two countries in selected texts of contemporary Dominican-American writers: Junot Díaz’s novel The Brief Wondrous Life of Oscar Wao and a short story “Monstro,” and Angie Cruz’s Soledad. It aims to analyze how the texts discuss the experience of in-betweenness through hybridity (for instance intertextuality and magical realism with the use of tools offered by the neo-baroque esthetics.   „Ani tu, ani tam”.

Organic Agriculture: Giving Low-Tech a Chance? An overview of the patent landscape: Tecnología artesanal? Revisión del panorama de patentamiento

Directory of Open Access Journals (Sweden)

Luis Gil Abinader

Full Text Available This research overview the patent landscape of the inputs approved for certified organic agriculture. For this, it explains the tensions in regards to private voluntary standards addressed in certain trade-related forums. A succinct characterization of the economic impact of plant diseases outbreaks in the Dominican Republic -an organic produce exporting countries- follows. It then briefly compares the "public" norms controlling the production and labeling of organic agriculture, with their "private" counterparts. Subsequently, the result of the patent searchers, which were performed taking into account the private voluntary certifiers' list of validated inputs, is reported. When the data is analyzed quantitatively, the finding suggests that there is no high intellectual property costs required to comply with the examined private voluntary standards. However, a small number of validated fungicides -which are also widely used by organic farmers in the Dominican Republic- may have significant intellectual property access barriers.

Institutional setting and wealth gradients in cesarean delivery rates: Evidence from six developing countries.

Science.gov (United States)

Sepehri, Ardeshir

2018-06-01

The influence of the type of institutional setting on cesarean delivery is well documented. However, the traditional boundaries between public and private providers have become increasingly blurred with the commercialization of the state health sector that allows providers to tailor the quantity and quality of care according to patients' ability to pay. This study examined wealth-related variations in cesarean rates in six lower- and upper-middle income countries: the Dominican Republic, Egypt, Guatemala, Jordan, Pakistan, and the Philippines. Demographic and Health Survey data and a hierarchical regression model were used to assess wealth-related variations in cesarean rates in government and private hospitals while controlling for a wide range of women's socioeconomic and risk profiles. The odds of undergoing a cesarean delivery were greater in private facilities than government hospitals by 58% in Jordan, 129% in Guatemala, and 262% and 279% in the Dominican Republic and Egypt, respectively. Additional analysis involving interactions between the type of facility and wealth quintiles indicated that wealthier women were more likely to undergo a cesarean birth in government hospitals than poorer women in all countries but the Dominican Republic and Guatemala. Moreover, in both Egypt and Jordan, differences in cesarean rates between government and private hospitals were smaller for the wealthier strata than for the nonwealthy. Large wealth-related variations in the mode of delivery across government and private hospitals suggest the need for well-developed guidelines and standards to achieve a more appropriate selection of cases for cesarean delivery. © 2018 Wiley Periodicals, Inc.

1985-03-01

The Fortescue field in the Gippsland Basin, offshore southeastern Australia is being developed from two platforms (Fortescue A and Cobia A) by Esso Australia Ltd. (operator) and BHP Petroleum. The Fortescue reservoir is a stratigraphic trap at the top of the Latrobe Group of sediments. It overlies the western flank of the Halibut and Cobia fields and is separated from them by a non-net sequence of shales and coals which form a hydraulic barrier between the two systems. Development drilling into the Fortescue reservoir commenced in April 1983 with production coming onstream in May 1983. Fortescue, with booked reserves of 44 stock tank gigalitres (280 million stock tank barrels) of 43/sup 0/ API oil, is the seventh major oil reservoir to be developed in the offshore Gippsland Basin by Esso/BHP. In mid-1984, after drilling a total of 20 exploration and development wells, and after approximately one year of production, a detailed three-dimensional, two-phase reservoir simulation study was performed to examine the recovery efficiency, drainage patterns, pressure performance and production rate potential of the reservoir. The model was validated by history matching an extensive suite of Repeat Formation Test (RFT) pressure data. The results confirmed the reserves basis, and demonstrated that the ultimate oil recovery from the reservoir is not sensitive to production rate. This result is consistent with studies on other high quality Latrobe Group reservoirs in the Gippsland Basin which contain undersaturated crudes and receive very strong water drive from the Basin-wide aquifer system. With the development of the simulation model during the development phase, it has been possible to more accurately define the optimal well pattern for the remainder of the development.

2007-01-01

This study presents descriptive qualitative data about Latino parenting practices in an urban context. Focus groups were conducted with Dominican and Puerto Rican mother-adolescent pairs in the Bronx borough of NewYork City. When parenting style typologies are integrated with the Latino cultural components familismo, respeto, personalismo, and simpatía, Latino parenting practices and their underlying styles are better understood. Content analysis of parents' focus groups revealed five essential Latino parenting practices: (1) ensuring close monitoring of adolescents; (2) maintaining warm and supportive relationships characterized by high levels of parent-adolescent interaction and sharing; (3) explaining parental decisions and actions; (4) making an effort to build and improve relationships; and (5) differential parenting practices based on adolescents' gender. Mothers reported concerns related to the risks associated with living in an urban area, exposure to different cultural values, and opportunities for engaging in risky behaviors. Adolescents' recommendations for effective parenting strategies were similar to the practices reported by their mothers. The study has important applied implications for culturally competent social work practice with Latino adolescents and their families.

Advantageous Reservoir Characterization Technology in Extra Low Permeability Oil Reservoirs

Directory of Open Access Journals (Sweden)

Yutian Luo

2017-01-01

Full Text Available This paper took extra low permeability reservoirs in Dagang Liujianfang Oilfield as an example and analyzed different types of microscopic pore structures by SEM, casting thin sections fluorescence microscope, and so on. With adoption of rate-controlled mercury penetration, NMR, and some other advanced techniques, based on evaluation parameters, namely, throat radius, volume percentage of mobile fluid, start-up pressure gradient, and clay content, the classification and assessment method of extra low permeability reservoirs was improved and the parameter boundaries of the advantageous reservoirs were established. The physical properties of reservoirs with different depth are different. Clay mineral variation range is 7.0%, and throat radius variation range is 1.81 μm, and start pressure gradient range is 0.23 MPa/m, and movable fluid percentage change range is 17.4%. The class IV reservoirs account for 9.56%, class II reservoirs account for 12.16%, and class III reservoirs account for 78.29%. According to the comparison of different development methods, class II reservoir is most suitable for waterflooding development, and class IV reservoir is most suitable for gas injection development. Taking into account the gas injection in the upper section of the reservoir, the next section of water injection development will achieve the best results.

Application of Integrated Reservoir Management and Reservoir Characterization to Optimize Infill Drilling

Energy Technology Data Exchange (ETDEWEB)

P. K. Pande

1998-10-29

Initial drilling of wells on a uniform spacing, without regard to reservoir performance and characterization, must become a process of the past. Such efforts do not optimize reservoir development as they fail to account for the complex nature of reservoir heterogeneities present in many low permeability reservoirs, and carbonate reservoirs in particular. These reservoirs are typically characterized by: o Large, discontinuous pay intervals o Vertical and lateral changes in reservoir properties o Low reservoir energy o High residual oil saturation o Low recovery efficiency

The role of reservoir characterization in the reservoir management process (as reflected in the Department of Energy`s reservoir management demonstration program)

1997-08-01

Optimum reservoir recovery and profitability result from guidance of reservoir practices provided by an effective reservoir management plan. Success in developing the best, most appropriate reservoir management plan requires knowledge and consideration of (1) the reservoir system including rocks, and rock-fluid interactions (i.e., a characterization of the reservoir) as well as wellbores and associated equipment and surface facilities; (2) the technologies available to describe, analyze, and exploit the reservoir; and (3) the business environment under which the plan will be developed and implemented. Reservoir characterization is the essential to gain needed knowledge of the reservoir for reservoir management plan building. Reservoir characterization efforts can be appropriately scaled by considering the reservoir management context under which the plan is being built. Reservoir management plans de-optimize with time as technology and the business environment change or as new reservoir information indicates the reservoir characterization models on which the current plan is based are inadequate. BDM-Oklahoma and the Department of Energy have implemented a program of reservoir management demonstrations to encourage operators with limited resources and experience to learn, implement, and disperse sound reservoir management techniques through cooperative research and development projects whose objectives are to develop reservoir management plans. In each of the three projects currently underway, careful attention to reservoir management context assures a reservoir characterization approach that is sufficient, but not in excess of what is necessary, to devise and implement an effective reservoir management plan.

To test whether Zika virus has adapted for more efficient transmission by Aedes aegypti mosquitoes, leading to recent urban outbreaks, we fed mosquitoes from Brazil, the Dominican Republic, and the United States artificial blood meals containing 1 of 3 Zika virus strains (Senegal, Cambodia, Mexico) and monitored infection, dissemination, and virus in saliva. Contrary to our hypothesis, Cambodia and Mexica strains were less infectious than the Senegal strain. Only mosquitoes from the Dominican Republic transmitted the Cambodia and Mexica strains. However, blood meals from viremic mice were more infectious than artificial blood meals of comparable doses; the Cambodia strain was not transmitted by mosquitoes from Brazil after artificial blood meals, whereas 61% transmission occurred after a murine blood meal (saliva titers up to 4 log 10 infectious units/collection). Although regional origins of vector populations and virus strain influence transmission efficiency, Ae. aegypti mosquitoes appear to be competent vectors of Zika virus in several regions of the Americas.

A bacterial spore was revived, cultured, and identified from the abdominal contents of extinct bees preserved for 25 to 40 million years in buried Dominican amber. Rigorous surface decontamination of the amber and aseptic procedures were used during the recovery of the bacterium. Several lines of evidence indicated that the isolated bacterium was of ancient origin and not an extant contaminant. The characteristic enzymatic, biochemical, and 16S ribosomal DNA profiles indicated that the ancient bacterium is most closely related to extant Bacillus sphaericus.

1997-01-01

In this paper the hydro energetic potential (HEP), that mean a sum of average yearly productions of built and realized hydroelectric power plants (HPP) and small hydroelectric power plants (SHPP) of the Slovak Republic is discussed. HEP is calculated by a value 7.361 GWh/years at appropriate installed capacity 2.575 MW. If HEP is expressed in the amount of brown coal which would be required for production of the same amount of electric (so called coal equivalent) we get the amount of about 8.4 mil tons of this kind of fuel yearly including all of the negative aspects resulting from burning this amount of coal. About 2.3 mil tons of ash, 176 ktons of sulphur oxides, etc for instance would be produced in a year. Utilization of HEP in the Slovak Republic by the end of 1995 reaches the value 3,918 GWh/year, i.e about 53.2%.

Building a Sustainable Global Surgical Program in an Academic Department of Surgery.

Science.gov (United States)

Zhang, Linda P; Silverberg, Daniel; Divino, Celia M; Marin, Michael

Global surgery and volunteerism in surgery has gained significant interest in recent years for general surgery residents across the country. However, there are few well-established long-term surgical programs affiliated with academic institutions. The present report discusses the implementation process and challenges facing an academic institution in building a long-term sustainable global surgery program. As one of the pioneer programs in global surgery for residents, the Icahn School of Medicine at Mount Sinai global surgery rotation has been successfully running for the last 10 years in a small public hospital in the Dominican Republic. The present report details many key components of implementing a sustainable global surgery program and the evolution of this program over time. Since 2005, 80 general surgery residents have rotated through Juan Pablo Pina Hospital in the Dominican Republic. They have performed a total of 1239 major operations and 740 minor operations. They have also participated in 328 emergency cases. More importantly, this rotation helped shape residents' sense of social responsibility and ownership in their surgical training. Residents have also contributed to the training of local residents in laparoscopic skills and through cultural exchange. As interest in global surgery grows among general surgery residents, it is essential that supporting academic institutions create sustainable and capacity-building rotations for their residents. These programs must address many of the barriers that can hinder maintenance of a sustainable global surgery experience for residents. After 10 years of sending our residents to the Dominican Republic, we have found that it is possible and valuable to incorporate a formal global surgery rotation into a general surgery residency.

The project objective was to detail better ways to assess and exploit intelligent oil and gas field information through improved modeling, sensor technology, and process control to increase ultimate recovery of domestic hydrocarbons. To meet this objective we investigated the use of permanent downhole sensors systems (Smart Wells) whose data is fed real-time into computational reservoir models that are integrated with optimized production control systems. The project utilized a three-pronged approach (1) a value of information analysis to address the economic advantages, (2) reservoir simulation modeling and control optimization to prove the capability, and (3) evaluation of new generation sensor packaging to survive the borehole environment for long periods of time. The Value of Information (VOI) decision tree method was developed and used to assess the economic advantage of using the proposed technology; the VOI demonstrated the increased subsurface resolution through additional sensor data. Our findings show that the VOI studies are a practical means of ascertaining the value associated with a technology, in this case application of sensors to production. The procedure acknowledges the uncertainty in predictions but nevertheless assigns monetary value to the predictions. The best aspect of the procedure is that it builds consensus within interdisciplinary teams The reservoir simulation and modeling aspect of the project was developed to show the capability of exploiting sensor information both for reservoir characterization and to optimize control of the production system. Our findings indicate history matching is improved as more information is added to the objective function, clearly indicating that sensor information can help in reducing the uncertainty associated with reservoir characterization. Additional findings and approaches used are described in detail within the report. The next generation sensors aspect of the project evaluated sensors and packaging

Large reservoirs: Chapter 17

Science.gov (United States)

Miranda, Leandro E.; Bettoli, Phillip William

2010-01-01

Large impoundments, defined as those with surface area of 200 ha or greater, are relatively new aquatic ecosystems in the global landscape. They represent important economic and environmental resources that provide benefits such as flood control, hydropower generation, navigation, water supply, commercial and recreational fisheries, and various other recreational and esthetic values. Construction of large impoundments was initially driven by economic needs, and ecological consequences received little consideration. However, in recent decades environmental issues have come to the forefront. In the closing decades of the 20th century societal values began to shift, especially in the developed world. Society is no longer willing to accept environmental damage as an inevitable consequence of human development, and it is now recognized that continued environmental degradation is unsustainable. Consequently, construction of large reservoirs has virtually stopped in North America. Nevertheless, in other parts of the world construction of large reservoirs continues. The emergence of systematic reservoir management in the early 20th century was guided by concepts developed for natural lakes (Miranda 1996). However, we now recognize that reservoirs are different and that reservoirs are not independent aquatic systems inasmuch as they are connected to upstream rivers and streams, the downstream river, other reservoirs in the basin, and the watershed. Reservoir systems exhibit longitudinal patterns both within and among reservoirs. Reservoirs are typically arranged sequentially as elements of an interacting network, filter water collected throughout their watersheds, and form a mosaic of predictable patterns. Traditional approaches to fisheries management such as stocking, regulating harvest, and in-lake habitat management do not always produce desired effects in reservoirs. As a result, managers may expend resources with little benefit to either fish or fishing. Some locally

Using combinations of methods for evaluating capacity of fissured reservoirs of the upper Cretaceous Malgobek- Voznesensk oil deposit in Ch. I. ASSR

Energy Technology Data Exchange (ETDEWEB)

Vasilev, V.M.

1968-01-01

Ch.I.ASSR stands for the Chechen-Ingush Autonomous Soviet Socialist Republic (North Caucasus). The deposit is associated with practically impervious limestones (less than 1 md) with intergranular porosity; oil is found along fractures of various length and degree of openness. Amount of fluids contained in this type of reservoirs was evaluated by the following methods: (1) core analyses; (2) geophysical surveying of wells; (3) hydrodynamic techniques of well investigations; and (4) according to parts of the deposits where oil was already recovered. Statistical interpretation of combined data indicated that reservoir properties gradually become poorer with increasing depth and in the direction from the crest of the fold towards its flanks and periclinal ends. Application of some formulas used in this work is explained. It is concluded that by using combinations of methods it is possible to evaluate the absolute and effective values of secondary reservoir capacity and to establish approximately geological and retrievable oil reserves.

Understanding the True Stimulated Reservoir Volume in Shale Reservoirs

KAUST Repository

Hussain, Maaruf

2017-06-06

Successful exploitation of shale reservoirs largely depends on the effectiveness of hydraulic fracturing stimulation program. Favorable results have been attributed to intersection and reactivation of pre-existing fractures by hydraulically-induced fractures that connect the wellbore to a larger fracture surface area within the reservoir rock volume. Thus, accurate estimation of the stimulated reservoir volume (SRV) becomes critical for the reservoir performance simulation and production analysis. Micro-seismic events (MS) have been commonly used as a proxy to map out the SRV geometry, which could be erroneous because not all MS events are related to hydraulic fracture propagation. The case studies discussed here utilized a fully 3-D simulation approach to estimate the SRV. The simulation approach presented in this paper takes into account the real-time changes in the reservoir\\'s geomechanics as a function of fluid pressures. It is consisted of four separate coupled modules: geomechanics, hydrodynamics, a geomechanical joint model for interfacial resolution, and an adaptive re-meshing. Reservoir stress condition, rock mechanical properties, and injected fluid pressure dictate how fracture elements could open or slide. Critical stress intensity factor was used as a fracture criterion governing the generation of new fractures or propagation of existing fractures and their directions. Our simulations were run on a Cray XC-40 HPC system. The studies outcomes proved the approach of using MS data as a proxy for SRV to be significantly flawed. Many of the observed stimulated natural fractures are stress related and very few that are closer to the injection field are connected. The situation is worsened in a highly laminated shale reservoir as the hydraulic fracture propagation is significantly hampered. High contrast in the in-situ stresses related strike-slip developed thereby shortens the extent of SRV. However, far field nature fractures that were not connected to

Effect of reservoir heterogeneity on air injection performance in a light oil reservoir

Directory of Open Access Journals (Sweden)

Hu Jia

2018-03-01

Full Text Available Air injection is a good option to development light oil reservoir. As well-known that, reservoir heterogeneity has great effect for various EOR processes. This also applies to air injection. However, oil recovery mechanisms and physical processes for air injection in heterogeneous reservoir with dip angle are still not well understood. The reported setting of reservoir heterogeneous for physical model or simulation model of air injection only simply uses different-layer permeability of porous media. In practice, reservoir heterogeneity follows the principle of geostatistics. How much of contrast in permeability actually challenges the air injection in light oil reservoir? This should be investigated by using layered porous medial settings of the classical Dykstra-Parsons style. Unfortunately, there has been no work addressing this issue for air injection in light oil reservoir. In this paper, Reservoir heterogeneity is quantified based on the use of different reservoir permeability distribution according to classical Dykstra-Parsons coefficients method. The aim of this work is to investigate the effect of reservoir heterogeneity on physical process and production performance of air injection in light oil reservoir through numerical reservoir simulation approach. The basic model is calibrated based on previous study. Total eleven pseudo compounders are included in this model and ten complexity of reactions are proposed to achieve the reaction scheme. Results show that oil recovery factor is decreased with the increasing of reservoir heterogeneity both for air and N2 injection from updip location, which is against the working behavior of air injection from updip location. Reservoir heterogeneity sometimes can act as positive effect to improve sweep efficiency as well as enhance production performance for air injection. High O2 content air injection can benefit oil recovery factor, also lead to early O2 breakthrough in heterogeneous reservoir. Well

Amplitude various offset is widely used in petroleum exploration as well as in petroleum development field. Generally, phenomenon of amplitude in various angles assumes reservoir’s layer is quite thick. It also means that the wave is assumed as a very high frequency. But, in natural condition, the seismic wave is band limited and has quite low frequency. Therefore, topic about amplitude various angles in thin layer reservoir as well as low frequency assumption is important to be considered. Thin layer reservoir means the thickness of reservoir is about or less than quarter of wavelength. In this paper, I studied about the reflection phenomena in elastic wave which considering interference from thin layer reservoir and transmission wave. I applied Zoeppritz equation for modeling reflected wave of top reservoir, reflected wave of bottom reservoir, and also transmission elastic wave of reservoir. Results show that the phenomena of AVA in thin layer reservoir are frequency dependent. Thin layer reservoir causes interference between reflected wave of top reservoir and reflected wave of bottom reservoir. These phenomena are frequently neglected, however, in real practices. Even though, the impact of inattention in interference phenomena caused by thin layer in AVA may cause inaccurate reservoir characterization. The relation between classes of AVA reservoir and reservoir’s character are different when effect of ones in thin reservoir and ones in thick reservoir are compared. In this paper, I present some AVA phenomena including its cross plot in various thin reservoir types based on some rock physics data of Indonesia.

The impact of access to immunization information on vaccine acceptance in three countries.

Directory of Open Access Journals (Sweden)

Lori K Handy

Full Text Available Vaccine acceptance is a critical component of sustainable immunization programs, yet rates of vaccine hesitancy are rising. Increased access to misinformation through media and anti-vaccine advocacy is an important contributor to hesitancy in the United States and other high-income nations with robust immunization programs. Little is known about the content and effect of information sources on attitudes toward vaccination in settings with rapidly changing or unstable immunization programs.The objective of this study was to explore knowledge and attitudes regarding vaccines and vaccine-preventable diseases among caregivers and immunization providers in Botswana, the Dominican Republic, and Greece and examine how access to information impacts reported vaccine acceptance.We conducted 37 focus groups and 14 semi-structured interviews with 96 providers and 153 caregivers in Botswana, the Dominican Republic, and Greece. Focus groups were conducted in Setswana, English, Spanish, or Greek; digitally recorded; and transcribed. Transcripts were translated into English, coded in qualitative data analysis software (NVivo 10, QSR International, Melbourne, Australia, and analyzed for common themes.Dominant themes in all three countries included identification of health care providers or medical literature as the primary source of vaccine information, yet participants reported insufficient communication about vaccines was available. Comments about level of trust in the health care system and government contrasted between sites, with the highest level of trust reported in Botswana but lower levels of trust in Greece.In Botswana, the Dominican Republic, and Greece, participants expressed reliance on health care providers for information and demonstrated a need for more communication about vaccines. Trust in the government and health care system influenced vaccine acceptance differently in each country, demonstrating the need for country-specific data that focus

[Eight criticisms of the draft of the migration law].

Science.gov (United States)

Lozano, W

1995-10-01

The proposed migration law recently published in the Dominican Republic is of importance because of the volume of both immigration to and emigration from the country. This critique of the draft is intended to stimulate debate before the proposed law is approved by the legislature. The proposed law is more a means of control and coercion than a modern instrument of development based on socioeconomic reality. A tendency to confuse the legal dispositions of migration control with migration policy is evident throughout the draft. However, the massive exodus of Dominicans and the massive entry of Haitians will not be resolved with simple measures of control. Migration policy should be related to development policy and to a strategy of insertion into the world economy. The proposed law assumes an authoritarian political order in a closed and intolerant oligarchic world. It ignores the fact that migration in the contemporary world is not a simple matter of border or police control, but of international relations, and that the treatment of Haitians in the Dominican Republic is not totally without relevance to the treatment of Dominicans in the US. The new law would weaken the authority of the consul and would concentrate power in the National Office of Migration, which would control migration and also be the judge in cases of conflict. The mechanisms proposed by the law for control of seasonal migratory labor assume a collective contract, when in fact most such labor is now contracted individually and informally by small enterprises. In general, the law sets up unrealistic requirements for entry and taxation of the poorly educated migrants. The National Office of Migration would be responsible for gathering and publishing such statistics as it deemed of interest, suggesting an intent to impede the free flow of information.

Analysis of renewable energy incentives in the Latin America and Caribbean region: The feed-in tariff case

International Nuclear Information System (INIS)

Jacobs, David; Marzolf, Natacha; Paredes, Juan Roberto; Rickerson, Wilson; Flynn, Hilary; Becker-Birck, Christina; Solano-Peralta, Mauricio

2013-01-01

Renewable energy is becoming a priority for Latin America and Caribbean (LAC) countries because of energy challenges such as demand growth, high dependence on imported fossil fuels, and climate change. As of 2010, 12 LAC countries have implemented formal targets for renewable energy deployment. Some of the LAC countries, namely Argentina, Dominican Republic, Ecuador, Honduras, and Nicaragua, are using feed-in tariffs (FITs) to promote renewables. FITs are long-term, guaranteed purchase agreements for green electricity at a price that can provide project developers a reasonable return on investment. FITs are increasingly popular because if designed well, they can mitigate investor risk in renewables. This article presents a low-risk FIT design and then uses this design to benchmark the existing LAC region FITs. - Highlights: ► 12 LAC countries have implemented formal targets for renewable energy deployment. ► Argentina, Dominican Republic, Ecuador, Honduras, and Nicaragua, are using feed-in tariffs (FITs) to promote renewables. ► Low-risk FIT design of feed-in tariffs in the LAC region can be improved

Multi-data reservoir history matching for enhanced reservoir forecasting and uncertainty quantification

KAUST Repository

Katterbauer, Klemens

2015-04-01

Reservoir simulations and history matching are critical for fine-tuning reservoir production strategies, improving understanding of the subsurface formation, and forecasting remaining reserves. Production data have long been incorporated for adjusting reservoir parameters. However, the sparse spatial sampling of this data set has posed a significant challenge for efficiently reducing uncertainty of reservoir parameters. Seismic, electromagnetic, gravity and InSAR techniques have found widespread applications in enhancing exploration for oil and gas and monitoring reservoirs. These data have however been interpreted and analyzed mostly separately, rarely exploiting the synergy effects that could result from combining them. We present a multi-data ensemble Kalman filter-based history matching framework for the simultaneous incorporation of various reservoir data such as seismic, electromagnetics, gravimetry and InSAR for best possible characterization of the reservoir formation. We apply an ensemble-based sensitivity method to evaluate the impact of each observation on the estimated reservoir parameters. Numerical experiments for different test cases demonstrate considerable matching enhancements when integrating all data sets in the history matching process. Results from the sensitivity analysis further suggest that electromagnetic data exhibit the strongest impact on the matching enhancements due to their strong differentiation between water fronts and hydrocarbons in the test cases.

2014-01-01

Full Text Available Natural fracture is a geological phenomenon widely distributed in tight formation, and fractured gas reservoir stimulation effect mainly depends on the communication of natural fractures. Therefore it is necessary to carry out the evaluation of this reservoir and to find out the optimal natural fractures development wells. By analyzing the interactions and nonlinear relationships of the parameters, it establishes three-level index system of reservoir evaluation and proposes a new method for gas well reservoir evaluation model in fractured gas reservoir on the basis of fuzzy logic theory and multilevel gray correlation. For this method, the Gaussian membership functions to quantify the degree of every factor in the decision-making system and the multilevel gray relation to determine the weight of each parameter on stimulation effect. Finally through fuzzy arithmetic operator between multilevel weights and fuzzy evaluation matrix, score, rank, the reservoir quality, and predicted production will be gotten. Result of this new method shows that the evaluation of the production coincidence rate reaches 80%, which provides a new way for fractured gas reservoir evaluation.

Reservoir Engineering Management Program

Energy Technology Data Exchange (ETDEWEB)

Howard, J.H.; Schwarz, W.J.

1977-12-14

The Reservoir Engineering Management Program being conducted at Lawrence Berkeley Laboratory includes two major tasks: 1) the continuation of support to geothermal reservoir engineering related work, started under the NSF-RANN program and transferred to ERDA at the time of its formation; 2) the development and subsequent implementation of a broad plan for support of research in topics related to the exploitation of geothermal reservoirs. This plan is now known as the GREMP plan. Both the NSF-RANN legacies and GREMP are in direct support of the DOE/DGE mission in general and the goals of the Resource and Technology/Resource Exploitation and Assessment Branch in particular. These goals are to determine the magnitude and distribution of geothermal resources and reduce risk in their exploitation through improved understanding of generically different reservoir types. These goals are to be accomplished by: 1) the creation of a large data base about geothermal reservoirs, 2) improved tools and methods for gathering data on geothermal reservoirs, and 3) modeling of reservoirs and utilization options. The NSF legacies are more research and training oriented, and the GREMP is geared primarily to the practical development of the geothermal reservoirs. 2 tabs., 3 figs.

Evaluation of an Empirical Reservoir Shape Function to Define Sediment Distributions in Small Reservoirs

Directory of Open Access Journals (Sweden)

Bogusław Michalec

2015-08-01

Full Text Available Understanding and defining the spatial distribution of sediment deposited in reservoirs is essential not only at the design stage but also during the operation. The majority of research concerns the distribution of sediment deposition in medium and large water reservoirs. Most empirical methods do not provide satisfactory results when applied to the determination of sediment deposition in small reservoirs. Small reservoir’s volumes do not exceed 5 × 106 m3 and their capacity-inflow ratio is less than 10%. Long-term silting measurements of three small reservoirs were used to evaluate the method described by Rahmanian and Banihashemi for predicting sediment distributions in small reservoirs. Rahmanian and Banihashemi stated that their model of distribution of sediment deposition in water reservoir works well for a long duration operation. In the presented study, the silting rate was used in order to determine the long duration operation. Silting rate is a quotient of volume of the sediment deposited in the reservoir and its original volume. It was stated that when the silting rate had reached 50%, the sediment deposition in the reservoir may be described by an empirical reservoir depth shape function (RDSF.

Full Text Available The aim of the study was to assess the degree of lead contamination in mallards in the Czech Republic as a result of using lead shots for wildfowling. Two sites used for mallard hunting were chosen, namely a flood-control reservoir in Moravia and a small fishpond in Bohemia. Lead concentrations were determined in the tissues of 20 mallards (Anas platyrhynchos raised at those standing open water sites (n = 10 at each site and killed there during the autumn hunting season with a steel shot. Control groups were made up of 20 mallards from the same breeding facility as experimental groups but raised in an enclosure without access to water (n = 10 at each site. Lead concentrations were determined in selected tissues (breast muscle, heart, liver, gizzard, kidney, feathers - quill base, lung, brain and humerus by high resolution continuum source atomic absorption spectrometry. The results showed elevated lead concentrations in all tissues of mallards compared with control in the reservoir in Southern Moravia. The highest lead concentrations (mg/kg were found in the humerus (14.254 ± 4.525 and 5.083 ± 0.748 for experimental and control mallards, respectively. In contrast, lead concentrations in mallards from small fishpond in Southern Bohemia were lower compared to control. Similarly, the highest lead concentrations were found in the humerus (2.219 ± 0.349 and 8.930 ± 1.012 for experimental and control mallards, respectively. This study extends very limited information about lead contamination of wild ducks in the Czech Republic in connection with hunting activities.

Modeling reservoir geomechanics using discrete element method : Application to reservoir monitoring

Energy Technology Data Exchange (ETDEWEB)

Alassi, Haitham Tayseer

2008-09-15

Understanding reservoir geomechanical behavior is becoming more and more important for the petroleum industry. Reservoir compaction, which may result in surface subsidence and fault reactivation, occurs during reservoir depletion. Stress changes and possible fracture development inside and outside a depleting reservoir can be monitored using time-lapse (so-called '4D') seismic and/or passive seismic, and this can give valuable information about the conditions of a given reservoir during production. In this study we will focus on using the (particle-based) Discrete Element Method (DEM) to model reservoir geomechanical behavior during depletion and fluid injection. We show in this study that DEM can be used in modeling reservoir geomechanical behavior by comparing results obtained from DEM to those obtained from analytical solutions. The match of the displacement field between DEM and the analytical solution is good, however there is mismatch of the stress field which is related to the way stress is measured in DEM. A good match is however obtained by measuring the stress field carefully. We also use DEM to model reservoir geomechanical behavior beyond the elasticity limit where fractures can develop and faults can reactivate. A general technique has been developed to relate DEM parameters to rock properties. This is necessary in order to use correct reservoir geomechanical properties during modeling. For any type of particle packing there is a limitation that the maximum ratio between P- and S-wave velocity Vp/Vs that can be modeled is 3 . The static behavior for a loose packing is different from the dynamic behavior. Empirical relations are needed for the static behavior based on numerical test observations. The dynamic behavior for both dense and loose packing can be given by analytical relations. Cosserat continuum theory is needed to derive relations for Vp and Vs. It is shown that by constraining the particle rotation, the S-wave velocity can be

Estimation of Bank Erosion Due To Reservoir Operation in Cascade (Case Study: Citarum Cascade Reservoir

2009-11-01

Full Text Available Sedimentation is such a crucial issue to be noted once the accumulated sediment begins to fill the reservoir dead storage, this will then influence the long-term reservoir operation. The sediment accumulated requires a serious attention for it may influence the storage capacity and other reservoir management of activities. The continuous inflow of sediment to the reservoir will decrease the capacity of reservoir storage, the reservoir value in use, and the useful age of reservoir. Because of that, the rate of the sediment needs to be delayed as possible. In this research, the delay of the sediment rate is considered based on the rate of flow of landslide of the reservoir slope. The rate of flow of the sliding slope can be minimized by way of each reservoir autonomous efforts. This effort can be performed through; the regulation of fluctuating rate of reservoir surface current that does not cause suddenly drawdown and upraising as well. The research model is compiled using the searching technique of Non Linear Programming (NLP.The rate of bank erosion for the reservoir variates from 0.0009 to 0.0048 MCM/year, which is no sigrificant value to threaten the life time of reservoir.Mean while the rate of watershed sediment has a significant value, i.e: 3,02 MCM/year for Saguling that causes to fullfill the storage capacity in 40 next years (from years 2008.

DEVELOPMENT OF RESERVOIR CHARACTERIZATION TECHNIQUES AND PRODUCTION MODELS FOR EXPLOITING NATURALLY FRACTURED RESERVOIRS

Energy Technology Data Exchange (ETDEWEB)

Michael L. Wiggins; Raymon L. Brown; Faruk Civan; Richard G. Hughes

2002-12-31

For many years, geoscientists and engineers have undertaken research to characterize naturally fractured reservoirs. Geoscientists have focused on understanding the process of fracturing and the subsequent measurement and description of fracture characteristics. Engineers have concentrated on the fluid flow behavior in the fracture-porous media system and the development of models to predict the hydrocarbon production from these complex systems. This research attempts to integrate these two complementary views to develop a quantitative reservoir characterization methodology and flow performance model for naturally fractured reservoirs. The research has focused on estimating naturally fractured reservoir properties from seismic data, predicting fracture characteristics from well logs, and developing a naturally fractured reservoir simulator. It is important to develop techniques that can be applied to estimate the important parameters in predicting the performance of naturally fractured reservoirs. This project proposes a method to relate seismic properties to the elastic compliance and permeability of the reservoir based upon a sugar cube model. In addition, methods are presented to use conventional well logs to estimate localized fracture information for reservoir characterization purposes. The ability to estimate fracture information from conventional well logs is very important in older wells where data are often limited. Finally, a desktop naturally fractured reservoir simulator has been developed for the purpose of predicting the performance of these complex reservoirs. The simulator incorporates vertical and horizontal wellbore models, methods to handle matrix to fracture fluid transfer, and fracture permeability tensors. This research project has developed methods to characterize and study the performance of naturally fractured reservoirs that integrate geoscience and engineering data. This is an important step in developing exploitation strategies for

Optimal Operation of Hydropower Reservoirs under Climate Change: The Case of Tekeze Reservoir, Eastern Nile

Directory of Open Access Journals (Sweden)

Fikru Fentaw Abera

2018-03-01

Full Text Available Optimal operation of reservoirs is very essential for water resource planning and management, but it is very challenging and complicated when dealing with climate change impacts. The objective of this paper was to assess existing and future hydropower operation at the Tekeze reservoir in the face of climate change. In this study, a calibrated and validated Soil and Water Assessment Tool (SWAT was used to model runoff inflow into the Tekeze hydropower reservoir under present and future climate scenarios. Inflow to the reservoir was simulated using hydro-climatic data from an ensemble of downscaled climate data based on the Coordinated Regional climate Downscaling Experiment over African domain (CORDEX-Africa with Coupled Intercomparison Project Phase 5 (CMIP5 simulations under Representative Concentration Pathway (RCP4.5 and RCP8.5 climate scenarios. Observed and projected inflows to Tekeze hydropower reservoir were used as input to the US Army Corps of Engineer’s Reservoir Evaluation System Perspective Reservoir Model (HEC-ResPRM, a reservoir operation model, to optimize hydropower reservoir release, storage and pool level. Results indicated that climate change has a clear impact on reservoir inflow and showed increase in annual and monthly inflow into the reservoir except in dry months from May to June under RCP4.5 and RCP8.5 climate scenarios. HEC-ResPRM optimal operation results showed an increase in Tekeze reservoir power storage potential up to 25% and 30% under RCP4.5 and RCP8.5 climate scenarios, respectively. This implies that Tekeze hydropower production will be affected by climate change. This analysis can be used by water resources planners and mangers to develop reservoir operation techniques considering climate change impact to increase power production.

Improving reservoir history matching of EM heated heavy oil reservoirs via cross-well seismic tomography

KAUST Repository

Katterbauer, Klemens

2014-01-01

Enhanced recovery methods have become significant in the industry\\'s drive to increase recovery rates from oil and gas reservoirs. For heavy oil reservoirs, the immobility of the oil at reservoir temperatures, caused by its high viscosity, limits the recovery rates and strains the economic viability of these fields. While thermal recovery methods, such as steam injection or THAI, have extensively been applied in the field, their success has so far been limited due to prohibitive heat losses and the difficulty in controlling the combustion process. Electromagnetic (EM) heating via high-frequency EM radiation has attracted attention due to its wide applicability in different environments, its efficiency, and the improved controllability of the heating process. While becoming a promising technology for heavy oil recovery, its effect on overall reservoir production and fluid displacements are poorly understood. Reservoir history matching has become a vital tool for the oil & gas industry to increase recovery rates. Limited research has been undertaken so far to capture the nonlinear reservoir dynamics and significantly varying flow rates for thermally heated heavy oil reservoir that may notably change production rates and render conventional history matching frameworks more challenging. We present a new history matching framework for EM heated heavy oil reservoirs incorporating cross-well seismic imaging. Interfacing an EM heating solver to a reservoir simulator via Andrade’s equation, we couple the system to an ensemble Kalman filter based history matching framework incorporating a cross-well seismic survey module. With increasing power levels and heating applied to the heavy oil reservoirs, reservoir dynamics change considerably and may lead to widely differing production forecasts and increased uncertainty. We have shown that the incorporation of seismic observations into the EnKF framework can significantly enhance reservoir simulations, decrease forecasting

1971-04-01

The Nagylengyel oil field, discovered in 1951, has oil-producing formations mostly in the Upper-Triassic dolomites, in the Norian-Ractian transition formations, in the Upper-Cretaceous limestones and shales, and in the Miocene. The formation of the reservoir space occurred in many stages. A porous, cavernous fractured reservoir is developed in the Norian principal dolomite. A cavernous fractured reservoir exists in the Cretaceous limestone and in the Cretaceous shale and porous fractured reservoir is developed in the Miocene. The derivation of the model of the reservoir, and the conservative evaluation of the volume of the reservoir made it possible to use secondary recovery.

Patient Disease Perceptions and Coping Strategies for Arthritis in a Developing Nation: A Qualitative Study

Directory of Open Access Journals (Sweden)

Bogart Laura M

2011-10-01

Full Text Available Abstract Background There is little prior research on the burden of arthritis in the developing world. We sought to document how patients with advanced arthritis living in the Dominican Republic are affected by and cope with their disease. Methods We conducted semi-structured, one-to-one interviews with economically disadvantaged Dominican patients with advanced knee and/or hip arthritis in the Dominican Republic. The interviews, conducted in Spanish, followed a moderator's guide that included topics such as the patients' understanding of disease etiology, their support networks, and their coping mechanisms. The interviews were audiotaped, transcribed verbatim in Spanish, and systematically analyzed using content analysis. We assessed agreement in coding between two investigators. Results 18 patients were interviewed (mean age 60 years, median age 62 years, 72% women, 100% response rate. Patients invoked religious and environmental theories of disease etiology, stating that their illness had been caused by God's will or through contact with water. While all patients experienced pain and functional limitation, the social effects of arthritis were gender-specific: women noted interference with homemaking and churchgoing activities, while men experienced disruption with occupational roles. The coping strategies used by patients appeared to reflect their beliefs about disease causation and included prayer and avoidance of water. Conclusions Patients' explanatory models of arthritis influenced the psychosocial effects of the disease and coping mechanisms used. Given the increasing reach of global health programs, understanding these culturally influenced perceptions of disease will be crucial in successfully treating chronic diseases in the developing world.

Available data on the coverage of prenatal care in Latin America were reviewed. In recent years, only Bolivia had a coverage of prenatal care of less than 50 per cent. More than 90 per cent of pregnant women received prenatal care in Chile, Cuba, the Dominican Republic, and Puerto Rico. Prenatal care increased between the 1970 and 1980 in the Dominican Republic, Ecuador, Guatemala, Honduras, Mexico, and Peru. The coverage of prenatal care decreased in Bolivia and Colombia. The mean number of visits increased in Cuba and Puerto Rico. The increase of prenatal care in Guatemala and Honduras is due to increased care by traditional birth attendants, compared to the role of health care institutions. We compared the more recent data on tetanus immunization of pregnant women to the more recent data on prenatal care. The rates of tetanus immunization are always lower than the rates of prenatal care attendance, except in Costa Rica. The rates of tetanus immunization was less than half as compared to the rates of prenatal care in Bolivia, Guatemala, and Peru. To improve the content of prenatal care should be an objective complementary to the increase of the number of attending women.

In December 2013, the World Health Organization reported the first local transmission of chikungunya virus in the Western Hemisphere, with autochthonous cases identified in Saint Martin. Since then, local transmission has been identified in 17 countries or territories in the Caribbean or South America (Anguilla, Antigua and Barbuda, British Virgin Islands, Dominica, Dominican Republic, French Guiana, Guadeloupe, Guyana, Haiti, Martinique, Puerto Rico, Saint Barthelemy, Saint Kitts and Nevis, Saint Lucia, Saint Martin, Saint Vincent and the Grenadines, and Sint Maarten). As of May 30, 2014, a total of 103,018 suspected and 4,406 laboratory-confirmed chikungunya cases had been reported from these areas. The number of reported cases nearly doubled during the previous 2 weeks. More than 95% of the cases have been reported from five jurisdictions: Dominican Republic (38,656 cases), Martinique (30,715), Guadeloupe (24,428), Haiti (6,318), and Saint Martin (4,113). The highest incidences have been reported from Saint Martin (115 cases per 1,000 population), Martinique (76 per 1,000), Saint Barthelemy (74 per 1,000), and Guadeloupe (52 per 1,000). Further expansion of these outbreaks and spread to other countries in the region is likely.

A Study of the Optimal Planning Model for Reservoir Sustainable Management- A Case Study of Shihmen Reservoir

Chen, Y. Y.; Ho, C. C.; Chang, L. C.

2017-12-01

The reservoir management in Taiwan faces lots of challenge. Massive sediment caused by landslide were flushed into reservoir, which will decrease capacity, rise the turbidity, and increase supply risk. Sediment usually accompanies nutrition that will cause eutrophication problem. Moreover, the unevenly distribution of rainfall cause water supply instability. Hence, how to ensure sustainable use of reservoirs has become an important task in reservoir management. The purpose of the study is developing an optimal planning model for reservoir sustainable management to find out an optimal operation rules of reservoir flood control and sediment sluicing. The model applies Genetic Algorithms to combine with the artificial neural network of hydraulic analysis and reservoir sediment movement. The main objective of operation rules in this study is to prevent reservoir outflow caused downstream overflow, minimum the gap between initial and last water level of reservoir, and maximum sluicing sediment efficiency. A case of Shihmen reservoir was used to explore the different between optimal operating rule and the current operation of the reservoir. The results indicate optimal operating rules tended to open desilting tunnel early and extend open duration during flood discharge period. The results also show the sluicing sediment efficiency of optimal operating rule is 36%, 44%, 54% during Typhoon Jangmi, Typhoon Fung-Wong, and Typhoon Sinlaku respectively. The results demonstrate the optimal operation rules do play a role in extending the service life of Shihmen reservoir and protecting the safety of downstream. The study introduces a low cost strategy, alteration of operation reservoir rules, into reservoir sustainable management instead of pump dredger in order to improve the problem of elimination of reservoir sediment and high cost.

Full Text Available Introduction: Water when harvested is commonly stored in dams, but approximately up to half of it may be lost due to evaporation leading to a huge waste of our resources. Estimating evaporation from lakes and reservoirs is not a simple task as there are a number of factors that can affect the evaporation rate, notably the climate and physiography of the water body and its surroundings. Several methods are currently used to predict evaporation from meteorological data in open water reservoirs. Based on the accuracy and simplicity of the application, each of these methods has advantages and disadvantages. Although evaporation pan method is well known to have significant uncertainties both in magnitude and timing, it is extensively used in Iran because of its simplicity. Evaporation pan provides a measurement of the combined effect of temperature, humidity, wind speed and solar radiation on the evaporation. However, they may not be adequate for the reservoir operations/development and water accounting strategies for managing drinking water in arid and semi-arid conditions which require accurate evaporation estimates. However, there has not been a consensus on which methods were better to employ due to the lack of important long-term measured data such as temperature profile, radiation and heat fluxes in most lakes and reservoirs in Iran. Consequently, we initiated this research to find the best cost−effective evaporation method with possibly fewer data requirements in our study area, i.e. the Doosti dam reservoir which is located in a semi-arid region of Iran. Materials and Methods: Our study site was the Doosti dam reservoir located between Iran and Turkmenistan borders, which was constructed by the Ministry of Water and Land Reclamation of the Republic of Turkmenistan and the Khorasan Razavi Regional Water Board of the Islamic Republic of Iran. Meteorological data including maximum and minimum air temperature and evaporation from class A pan

Reservoir Computing is a novel computing paradigm that uses a nonlinear recurrent dynamical system to carry out information processing. Recent electronic and optoelectronic Reservoir Computers based on an architecture with a single nonlinear node and a delay loop have shown performance on standardized tasks comparable to state-of-the-art digital implementations. Here we report an all-optical implementation of a Reservoir Computer, made of off-the-shelf components for optical telecommunications. It uses the saturation of a semiconductor optical amplifier as nonlinearity. The present work shows that, within the Reservoir Computing paradigm, all-optical computing with state-of-the-art performance is possible.

Phenotypic plasticity in fish life-history traits in two neotropical reservoirs: Petit-Saut Reservoir in French Guiana and Brokopondo Reservoir in Suriname

Directory of Open Access Journals (Sweden)

Bernard de Mérona

Full Text Available Fish species are known for their large phenotypic plasticity in life-history traits in relation to environmental characteristics. Plasticity allows species to increase their fitness in a given environment. Here we examined the life-history response of fish species after an abrupt change in their environment caused by the damming of rivers. Two reservoirs of different age, both situated on the Guiana Shield, were investigated: the young Petit-Saut Reservoir in French Guiana (14 years and the much older Brokopondo Reservoir in Suriname (44 years. Six life-history traits in 14 fish species were studied and compared to their value in the Sinnamary River prior to the completion of Petit-Saut Reservoir. The traits analyzed were maximum length, absolute and relative length at first maturation, proportion of mature oocytes in ripe gonad, batch fecundity and mean size of mature oocytes. The results revealed a general increase of reproductive effort. All species showed a decrease in maximum length. Compared to the values observed before the dam constructions, eight species had larger oocytes and three species showed an increased batch fecundity. These observed changes suggest a trend towards a pioneer strategy. The changes observed in Petit-Saut Reservoir also seemed to apply to the 30 years older Brokopondo Reservoir suggesting that these reservoirs remain in a state of immaturity for a long time.

All natural lakes and reservoirs whether on rivers, tributaries or off channel storages are doomed to be sited up. Pakistan has two major reservoirs of Tarbela and Managla and shallow lake created by Chashma Barrage. Tarbela and Mangla Lakes are losing their capacities ever since first impounding, Tarbela since 1974 and Mangla since 1967. Tarbela Reservoir receives average annual flow of about 62 MAF and sediment deposits of 0.11 MAF whereas Mangla gets about 23 MAF of average annual flows and is losing its storage at the rate of average 34,000 MAF annually. The loss of storage is a great concern and studies for Tarbela were carried out by TAMS and Wallingford to sustain its capacity whereas no study has been done for Mangla as yet except as part of study for Raised Mangla, which is only desk work. Delta of Tarbala reservoir has advanced to about 6.59 miles (Pivot Point) from power intakes. In case of liquefaction of delta by tremor as low as 0.12g peak ground acceleration the power tunnels I, 2 and 3 will be blocked. Minimum Pool of reservoir is being raised so as to check the advance of delta. Mangla delta will follow the trend of Tarbela. Tarbela has vast amount of data as reservoir is surveyed every year, whereas Mangla Reservoir survey was done at five-year interval, which has now been proposed .to be reduced to three-year interval. In addition suspended sediment sampling of inflow streams is being done by Surface Water Hydrology Project of WAPDA as also some bed load sampling. The problem of Chasma Reservoir has also been highlighted, as it is being indiscriminately being filled up and drawdown several times a year without regard to its reaction to this treatment. The Sediment Management of these reservoirs is essential and the paper discusses pros and cons of various alternatives. (author)

Advances in photonic reservoir computing

Van der Sande, Guy; Brunner, Daniel; Soriano, Miguel C.

2017-05-01

We review a novel paradigm that has emerged in analogue neuromorphic optical computing. The goal is to implement a reservoir computer in optics, where information is encoded in the intensity and phase of the optical field. Reservoir computing is a bio-inspired approach especially suited for processing time-dependent information. The reservoir's complex and high-dimensional transient response to the input signal is capable of universal computation. The reservoir does not need to be trained, which makes it very well suited for optics. As such, much of the promise of photonic reservoirs lies in their minimal hardware requirements, a tremendous advantage over other hardware-intensive neural network models. We review the two main approaches to optical reservoir computing: networks implemented with multiple discrete optical nodes and the continuous system of a single nonlinear device coupled to delayed feedback.

A simple fish-based approach to assess the ecological quality of freshwater reservoirs in Central Europe

Directory of Open Access Journals (Sweden)

Blabolil Petr

2017-01-01

Full Text Available The assessment of ecological quality in freshwater ecosystems is a key issue in many countries, but conditions for the development of assessment methodologies are often country-specific. This study proposes a simple methodology for the assessment of the ecological potential of reservoirs based on fish communities using a dataset covering major environmental and pressure gradients in reservoirs in the Czech Republic. Fish data obtained by gillnet sampling were correlated with a proxy of eutrophication as a key indicator of anthropogenic pressure for selecting appropriate fish-based indicators, establishing scoring criteria and developing the index of ecological quality. Expert judgement was also used to select potential fish indicators. Nine indicators were selected for the final fish-based index, fulfilling the criteria required by the Water Framework Directive. Two steps were used to validate the fish-based index quantification of its inter annual stability and sensitivity analysis of individual indicators. Finally, the index was compared to a previously developed general index for Central and Western Europe. Our study demonstrates that a combination of expert judgement and strict validation methods can result in an informative assessment of the ecological conditions, which can help identify conservation and restoration priorities.

Danjiangkou Reservoir is the source reservoir of the Middle Route of the South-to-North Water Diversion Project (MRP). Any sudden water pollution accident in the reservoir would threaten the water supply of the MRP. We established a 3-D hydrodynamic and water quality model for the Danjiangkou Reservoir, and proposed scientific suggestions on the prevention and emergency management for sudden water pollution accidents based on simulated results. Simulations were performed on 20 hypothetical pollutant discharge locations and 3 assumed amounts, in order to model the effect of pollutant spreading under different reservoir operation types. The results showed that both the location and mass of pollution affected water quality; however, different reservoir operation types had little effect. Five joint regulation scenarios, which altered the hydrodynamic processes of water conveyance for the Danjiangkou and Taocha dams, were considered for controlling pollution dispersion. The results showed that the spread of a pollutant could be effectively controlled through the joint regulation of the two dams and that the collaborative operation of the Danjiangkou and Taocha dams is critical for ensuring the security of water quality along the MRP.

Quantification of Libby Reservoir Levels Needed to Maintain or Enhance Reservoir Fisheries, 1983-1987 Methods and Data Summary.

Chisholm, Ian

1989-12-01

Libby Reservoir was created under an International Columbia River Treaty between the United States and Canada for cooperative water development of the Columbia River Basin. The authorized purpose of the dam is to provide power, flood control, and navigation and other benefits. Research began in May 1983 to determine how operations of Libby dam impact the reservoir fishery and to suggest ways to lessen these impacts. This study is unique in that it was designed to accomplish its goal through detailed information gathering on every trophic level in the reservoir system and integration of this information into a quantitative computer model. The specific study objectives are to: quantify available reservoir habitat, determine abundance, growth and distribution of fish within the reservoir and potential recruitment of salmonids from Libby Reservoir tributaries within the United States, determine abundance and availability of food organisms for fish in the reservoir, quantify fish use of available food items, develop relationships between reservoir drawdown and reservoir habitat for fish and fish food organisms, and estimate impacts of reservoir operation on the reservoir fishery. 115 refs., 22 figs., 51 tabs.

Full Text Available In the Songliao Basin, volcanic oil and gas reservoirs are important exploration domains. Based on drilling, logging, and 3D seismic (1495 km2 data, 546 sets of measured physical properties and gas testing productivity of 66 wells in the Changling fault depression, Songliao Basin, eruptive cycles and sub-lithofacies were distinguished after lithologic correction of the 19,384 m volcanic well intervals, so that a quantitative analysis was conducted on the relation between the eruptive cycles, lithologies and lithofacies and the distribution of effective reservoirs. After the relationship was established between lithologies, lithofacies & cycles and reservoir physical properties & oil and gas bearing situations, an analysis was conducted on the characteristics of volcanic reservoirs and the distribution rules of effective reservoirs. It is indicated that 10 eruptive cycles of 3 sections are totally developed in this area, and the effective reservoirs are mainly distributed at the top cycles of eruptive sequences, with those of the 1st and 3rd Members of Yingcheng Formation presenting the best reservoir properties. In this area, there are mainly 11 types of volcanic rocks, among which rhyolite, rhyolitic tuff, rhyolitic tuffo lava and rhyolitic volcanic breccia are the dominant lithologies of effective reservoirs. In the target area are mainly developed 4 volcanic lithofacies (11 sub-lithofacies, among which upper sub-lithofacies of effusive facies and thermal clastic sub-lithofacies of explosion lithofacies are predominant in effective reservoirs. There is an obvious corresponding relationship between the physical properties of volcanic reservoirs and the development degree of effective reservoirs. The distribution of effective reservoirs is controlled by reservoir physical properties, and the formation of effective reservoirs is influenced more by porosity than by permeability. It is concluded that deep volcanic gas exploration presents a good

Despite declining production rates, existing reservoirs in the United States contain vast volumes of remaining oil that is not being effectively recovered. This oil resource constitutes a huge target for the development and application of modern, cost-effective technologies for producing oil. Chief among the barriers to the recovery of this oil are the high costs of designing and implementing conventional advanced recovery technologies in these mature, in many cases pressure-depleted, reservoirs. An additional, increasingly significant barrier is the lack of vital technical expertise necessary for the application of these technologies. This lack of expertise is especially notable among the small operators and independents that operate many of these mature, yet oil-rich, reservoirs. We addressed these barriers to more effective oil recovery by developing, testing, applying, and documenting an innovative technology that can be used by even the smallest operator to significantly increase the flow of oil from mature U.S. reservoirs. The Bureau of Economic Geology and Goldrus Producing Company assembled a multidisciplinary team of geoscientists and engineers to evaluate the applicability of high-pressure air injection (HPAI) in revitalizing a nearly abandoned carbonate reservoir in the Permian Basin of West Texas. The Permian Basin, the largest oil-bearing basin in North America, contains more than 70 billion barrels of remaining oil in place and is an ideal venue to validate this technology. We have demonstrated the potential of HPAI for oil-recovery improvement in preliminary laboratory tests and a reservoir pilot project. To more completely test the technology, this project emphasized detailed characterization of reservoir properties, which were integrated to access the effectiveness and economics of HPAI. The characterization phase of the project utilized geoscientists and petroleum engineers from the Bureau of Economic Geology and the Department of Petroleum

HydroSCOPE (Hydropower Seasonal Concurrent Optimization of Power and the Environment) is a seasonal time-scale tool for scenario analysis and optimization of reservoir-river networks. Developed in MATLAB, HydroSCOPE is an object-oriented model that simulates basin-scale dynamics with an objective of optimizing reservoir operations to maximize revenue from power generation, reliability in the water supply, environmental performance, and flood control. HydroSCOPE is part of a larger toolset that is being developed through a Department of Energy multi-laboratory project. This project's goal is to provide conventional hydropower decision makers with better information to execute their day-ahead and seasonal operations and planning activities by integrating water balance and operational dynamics across a wide range of spatial and temporal scales. This presentation details the modeling approach and functionality of HydroSCOPE. HydroSCOPE consists of a river-reservoir network model and an optimization routine. The river-reservoir network model simulates the heat and water balance of river-reservoir networks for time-scales up to one year. The optimization routine software, DAKOTA (Design Analysis Kit for Optimization and Terascale Applications - dakota.sandia.gov), is seamlessly linked to the network model and is used to optimize daily volumetric releases from the reservoirs to best meet a set of user-defined constraints, such as maximizing revenue while minimizing environmental violations. The network model uses 1-D approximations for both the reservoirs and river reaches and is able to account for surface and sediment heat exchange as well as ice dynamics for both models. The reservoir model also accounts for inflow, density, and withdrawal zone mixing, and diffusive heat exchange. Routing for the river reaches is accomplished using a modified Muskingum-Cunge approach that automatically calculates the internal timestep and sub-reach lengths to match the conditions of

Cesium reservoir and interconnective components

International Nuclear Information System (INIS)

1994-03-01

The program objective is to demonstrate the technology readiness of a TFE (thermionic fuel element) suitable for use as the basic element in a thermionic reactor with electric power output in the 0.5 to 5.0 MW range. A thermionic converter must be supplied with cesium vapor for two reasons. Cesium atoms adsorbed on the surface of the emitter cause a reduction of the emitter work function to permit high current densities without excessive heating of the emitter. The second purpose of the cesium vapor is to provide space-charge neutralization in the emitter-collector gap so that the high current densities may flow across the gap unattenuated. The function of the cesium reservoir is to provide a source of cesium atoms, and to provide a reserve in the event that cesium is lost from the plasma by any mechanism. This can be done with a liquid cesium metal reservoir in which case it is heated to the desired temperature with auxiliary heaters. In a TFE, however, it is desirable to have the reservoir passively heated by the nuclear fuel. In this case, the reservoir must operate at a temperature intermediate between the emitter and the collector, ruling out the use of liquid reservoirs. Integral reservoirs contained within the TFE will produce cesium vapor pressures in the desired range at typical electrode temperatures. The reservoir material that appears to be the best able to meet requirements is graphite. Cesium intercalates easily into graphite, and the cesium pressure is insensitive to loading for a given intercalation stage. The goals of the cesium reservoir test program were to verify the performance of Cs-graphite reservoirs in the temperature-pressure range of interest to TFE operation, and to test the operation of these reservoirs after exposure to a fast neutron fluence corresponding to seven year mission lifetime. In addition, other materials were evaluated for possible use in the integral reservoir

An integrated geological/petrophysical and reservoir engineering study was performed for a large, mature waterflood project (>250 wells, {approximately}80% water cut) at the North Robertson (Clear Fork) Unit, Gaines County, Texas. The primary goal of the study was to develop an integrated reservoir description for {open_quotes}targeted{close_quotes} (economic) 10-acre (4-hectare) infill drilling and future recovery operations in a low permeability, carbonate (dolomite) reservoir. Integration of the results from geological/petrophysical studies and reservoir performance analyses provide a rapid and effective method for developing a comprehensive reservoir description. This reservoir description can be used for reservoir flow simulation, performance prediction, infill targeting, waterflood management, and for optimizing well developments (patterns, completions, and stimulations). The following analyses were performed as part of this study: (1) Geological/petrophysical analyses: (core and well log data) - {open_quotes}Rock typing{close_quotes} based on qualitative and quantitative visualization of pore-scale features. Reservoir layering based on {open_quotes}rock typing {close_quotes} and hydraulic flow units. Development of a {open_quotes}core-log{close_quotes} model to estimate permeability using porosity and other properties derived from well logs. The core-log model is based on {open_quotes}rock types.{close_quotes} (2) Engineering analyses: (production and injection history, well tests) Material balance decline type curve analyses to estimate total reservoir volume, formation flow characteristics (flow capacity, skin factor, and fracture half-length), and indications of well/boundary interference. Estimated ultimate recovery analyses to yield movable oil (or injectable water) volumes, as well as indications of well and boundary interference.

Full Text Available Ebola and Marburg viruses (family Filoviridae, genera Ebolavirus and Marburgvirus cause haemorrhagic fevers in humans, often associated with high mortality rates. The presence of antibodies to Ebola virus (EBOV and Marburg virus (MARV has been reported in some African countries in individuals without a history of haemorrhagic fever. In this study, we present a MARV and EBOV seroprevalence study conducted amongst blood donors in the Republic of Congo and the analysis of risk factors for contact with EBOV.In 2011, we conducted a MARV and EBOV seroprevalence study amongst 809 blood donors recruited in rural (75; 9.3% and urban (734; 90.7% areas of the Republic of Congo. Serum titres of IgG antibodies to MARV and EBOV were assessed by indirect double-immunofluorescence microscopy. MARV seroprevalence was 0.5% (4 in 809 without any identified risk factors. Prevalence of IgG to EBOV was 2.5%, peaking at 4% in rural areas and in Pointe Noire. Independent risk factors identified by multivariate analysis were contact with bats and exposure to birds.This MARV and EBOV serological survey performed in the Republic of Congo identifies a probable role for environmental determinants of exposure to EBOV. It highlights the requirement for extending our understanding of the ecological and epidemiological risk of bats (previously identified as a potential ecological reservoir and birds as vectors of EBOV to humans, and characterising the protection potentially afforded by EBOV-specific antibodies as detected in blood donors.

Full Text Available Reservoir sedimentation and its effect on the environment are the most serious world-wide problems in water resources development and utilization today. As one of the largest water conservancy projects, the Three Gorges Reservoir (TGR has been controversial since its demonstration period, and sedimentation is the major concern. Due to the complex physical mechanisms of water and sediment transport, this study adopts the Error Back Propagation Training Artificial Neural Network (BP-ANN to analyze the relationship between the sediment flushing efficiency of the TGR and its influencing factors. The factors are determined by the analysis on 1D unsteady flow and sediment mathematical model, mainly including reservoir inflow, incoming sediment concentration, reservoir water level, and reservoir release. Considering the distinguishing features of reservoir sediment delivery in different seasons, the monthly average data from 2003, when the TGR was put into operation, to 2011 are used to train, validate, and test the BP-ANN model. The results indicate that, although the sample space is quite limited, the whole sediment delivery process can be schematized by the established BP-ANN model, which can be used to help sediment flushing and thus decrease the reservoir sedimentation.

Sweet spots identification for unconventional shale reservoirs involves detection of organic-rich zones with abundant porosity. However, commonly used elastic attributes, such as P- and S-impedances, often show poor correlations with porosity and organic matter content separately and thus make the seismic characterization of sweet spots challenging. Based on an extensive analysis of worldwide laboratory database of core measurements, we find that P- and S-impedances exhibit much improved linear correlations with the sum of volume fraction of organic matter and porosity than the single parameter of organic matter volume fraction or porosity. Importantly, from the geological perspective, porosity in conjunction with organic matter content is also directly indicative of the total hydrocarbon content of shale resources plays. Consequently, we propose an effective reservoir parameter (ERP), the sum of volume fraction of organic matter and porosity, to bridge the gap between hydrocarbon accumulation and seismic measurements in organic shale reservoirs. ERP acts as the first-order factor in controlling the elastic properties as well as characterizing the hydrocarbon storage capacity of organic shale reservoirs. We also use rock physics modeling to demonstrate why there exists an improved linear correlation between elastic impedances and ERP. A case study in a shale gas reservoir illustrates that seismic-derived ERP can be effectively used to characterize the total gas content in place, which is also confirmed by the production well.

Accumulation and flow mechanisms in unconventional reservoir are different compared to conventional. This requires a special approach of field management with drilling and stimulation treatments as major factor for further production. Integrated approach of unconventional reservoir production optimization assumes coupling drilling project with full scale reservoir simulation for determine best well placement, well length, fracturing treatment design and mid-length distance between wells. Full scale reservoir simulation model emulate a part of polish shale - gas field. The aim of this paper is to establish influence of technical factor for gas production from shale gas field. Due to low reservoir permeability, stimulation treatment should be direct towards maximizing the hydraulic contact. On the basis of production scenarios, 15 stages hydraulic fracturing allows boost gas production over 1.5 times compared to 8 stages. Due to the possible interference of the wells, it is necessary to determine the distance between the horizontal parts of the wells trajectories. In order to determine the distance between the wells allowing to maximize recovery factor of resources in the stimulated zone, a numerical algorithm based on a dynamic model was developed and implemented. Numerical testing and comparative study show that the most favourable arrangement assumes a minimum allowable distance between the wells. This is related to the volume ratio of the drainage zone to the total volume of the stimulated zone.

Reservoir floodplains support distinct fish assemblages

Reservoirs constructed on floodplain rivers are unique because the upper reaches of the impoundment may include extensive floodplain environments. Moreover, reservoirs that experience large periodic water level fluctuations as part of their operational objectives seasonally inundate and dewater floodplains in their upper reaches, partly mimicking natural inundations of river floodplains. In four flood control reservoirs in Mississippi, USA, we explored the dynamics of connectivity between reservoirs and adjacent floodplains and the characteristics of fish assemblages that develop in reservoir floodplains relative to those that develop in reservoir bays. Although fish species richness in floodplains and bays were similar, species composition differed. Floodplains emphasized fish species largely associated with backwater shallow environments, often resistant to harsh environmental conditions. Conversely, dominant species in bays represented mainly generalists that benefit from the continuous connectivity between the bay and the main reservoir. Floodplains in the study reservoirs provided desirable vegetated habitats at lower water level elevations, earlier in the year, and more frequently than in bays. Inundating dense vegetation in bays requires raising reservoir water levels above the levels required to reach floodplains. Therefore, aside from promoting distinct fish assemblages within reservoirs and helping promote diversity in regulated rivers, reservoir floodplains are valued because they can provide suitable vegetated habitats for fish species at elevations below the normal pool, precluding the need to annually flood upland vegetation that would inevitably be impaired by regular flooding.

This project increased recoverable waterflood reserves in slope and basin reservoirs through improved reservoir characterization and reservoir management. The particular application of this project is in portions of Fault Blocks IV and V of the Wilmington Oil Field, in Long Beach, California, but the approach is widely applicable in slope and basin reservoirs. Transferring technology so that it can be applied in other sections of the Wilmington Field and by operators in other slope and basin reservoirs is a primary component of the project. This project used advanced reservoir characterization tools, including the pulsed acoustic cased-hole logging tool, geologic three-dimensional (3-D) modeling software, and commercially available reservoir management software to identify sands with remaining high oil saturation following waterflood. Production from the identified high oil saturated sands was stimulated by recompleting existing production and injection wells in these sands using conventional means as well as a short radius redrill candidate. Although these reservoirs have been waterflooded over 40 years, researchers have found areas of remaining oil saturation. Areas such as the top sand in the Upper Terminal Zone Fault Block V, the western fault slivers of Upper Terminal Zone Fault Block V, the bottom sands of the Tar Zone Fault Block V, and the eastern edge of Fault Block IV in both the Upper Terminal and Lower Terminal Zones all show significant remaining oil saturation. Each area of interest was uncovered emphasizing a different type of reservoir characterization technique or practice. This was not the original strategy but was necessitated by the different levels of progress in each of the project activities.

Exploration and reservoir characterization; Technology Target Areas; TTA2 - Exploration and reservoir characterisation

Energy Technology Data Exchange (ETDEWEB)

2008-07-01

In future, research within exploration and reservoir characterization will play an even more important role for Norway since resources are decreasing and new challenges like deep sea, harsh environment and last but not least environmental issues have to be considered. There are two major fields which have to be addressed within exploration and reservoir characterization: First, replacement of reserves by new discoveries and ultimate field recoveries in mature basins at the Norwegian Continental shelf, e.g. at the Halten Terrace has to be addressed. A wealth of data exists in the more mature areas. Interdisciplinary integration is a key feature of reservoir characterization, where available data and specialist knowledge need to be combined into a consistent reservoir description. A systematic approach for handling both uncertainties in data sources and uncertainties in basic models is needed. Fast simulation techniques are necessary to generate models spanning the event space, covering both underground based and model-based uncertainties. Second, exploration in frontier areas like the Barents Sea region and the deeper Voering Basin has to be addressed. The scarcity of wells in these frontier areas leads to uncertainties in the geological understanding. Basin- and depositional modelling are essential for predicting where source rocks and reservoir rocks are deposited, and if, when and which hydrocarbons are generated and trapped. Predictive models and improved process understanding is therefore crucial to meet these issues. Especially the challenges related to the salt deposits e.g. sub-salt/sub-basalt reservoir definitions in the Nordkapp Basin demands up-front research and technology developments. TTA2 stresses the need to focus on the development of new talents. We also see a strong need to push cooperation as far as possible in the present competitive environment. Projects that may require a substantial financial commitment have been identified. The following

The Department of Energy's (DOE's) Oil Recovery Field Demonstration Program was initiated in 1992 to maximize the economically and environmentally sound recovery of oil from known domestic reservoirs and to preserve access to this resource. Cost-shared field demonstration projects are being initiated in geology defined reservoir classes which have been prioritized by their potential for incremental recovery and their risk of abandonment. This document defines the characteristics of the fifth geological reservoir class in the series, fluvial/alluvial reservoirs. The reservoirs of Class 5 include deposits of alluvial fans, braided streams, and meandering streams. Deposit morphologies vary as a complex function of climate and tectonics and are characterized by a high degree of heterogeneity to fluid flow as a result of extreme variations in water energy as the deposits formed.

In the study of gas reservoir development, the first year topics are restricted on reservoir characterization. There are two types of reservoir characterization. One is the reservoir formation characterization and the other is the reservoir fluid characterization. For the reservoir formation characterization, calculation of conditional simulation was compared with that of unconditional simulation. The results of conditional simulation has higher confidence level than the unconditional simulation because conditional simulation considers the sample location as well as distance correlation. In the reservoir fluid characterization, phase behavior calculations revealed that the component grouping is more important than the increase of number of components. From the liquid volume fraction with pressure drop, the phase behavior of reservoir fluid can be estimated. The calculation results of fluid recombination, constant composition expansion, and constant volume depletion are matched very well with the experimental data. In swelling test of the reservoir fluid with lean gas, the accuracy of dew point pressure forecast depends on the component characterization. (author). 28 figs., 10 tabs.

Advances in photonic reservoir computing

2017-05-01

Full Text Available We review a novel paradigm that has emerged in analogue neuromorphic optical computing. The goal is to implement a reservoir computer in optics, where information is encoded in the intensity and phase of the optical field. Reservoir computing is a bio-inspired approach especially suited for processing time-dependent information. The reservoir’s complex and high-dimensional transient response to the input signal is capable of universal computation. The reservoir does not need to be trained, which makes it very well suited for optics. As such, much of the promise of photonic reservoirs lies in their minimal hardware requirements, a tremendous advantage over other hardware-intensive neural network models. We review the two main approaches to optical reservoir computing: networks implemented with multiple discrete optical nodes and the continuous system of a single nonlinear device coupled to delayed feedback.

An index of reservoir habitat impairment

Miranda, L.E.; Hunt, K.M.

2011-01-01

Fish habitat impairment resulting from natural and anthropogenic watershed and in-lake processes has in many cases reduced the ability of reservoirs to sustain native fish assemblages and fisheries quality. Rehabilitation of impaired reservoirs is hindered by the lack of a method suitable for scoring impairment status. To address this limitation, an index of reservoir habitat impairment (IRHI) was developed by merging 14 metrics descriptive of common impairment sources, with each metric scored from 0 (no impairment) to 5 (high impairment) by fisheries scientists with local knowledge. With a plausible range of 5 to 25, distribution of the IRHI scores ranged from 5 to 23 over 482 randomly selected reservoirs dispersed throughout the USA. The IRHI reflected five impairment factors including siltation, structural habitat, eutrophication, water regime, and aquatic plants. The factors were weakly related to key reservoir characteristics including reservoir area, depth, age, and usetype, suggesting that common reservoir descriptors are poor predictors of fish habitat impairment. The IRHI is rapid and inexpensive to calculate, provides an easily understood measure of the overall habitat impairment, allows comparison of reservoirs and therefore prioritization of restoration activities, and may be used to track restoration progress. The major limitation of the IRHI is its reliance on unstandardized professional judgment rather than standardized empirical measurements. ?? 2010 US Government.

No other country in the world has so few resources of fossil sources of energy and depends on imports of power as the Republic of Korea. As a consequence of economical and political processes of globalization, new challenges are developed: elevated regional and global conflicts relating to resources as well as new possibilities of cooperation by means of amore intensely international division of labour. Under this aspect, the author of the contribution under consideration reports on the energy policy of the Republic of Korea. Especially, the author reports on the following aspects: (a) Characteristics of the power structure of the Republic of Korea; (b) National energy policy and measures for energy security; (c) Practical measures of energy security; (d) Regional co-operation for energy security from the view of the Republic of Korea. The Republic of Korea has a very weak energy structure and strongly depends on foreign countries. Among the successful measures of energy security, there exist measures for energy saving in industrial areas, diversification of sources of energy and exporting countries, increase of competitiveness of the energy economy due to restructuring and privatization of national companies as well as liberalisation of the energy market. Investments in the research of energy saving technologies and renewable energy such as solar energy, hydraulic power and fuel cells are trend-setting. The development of new sources of energy and the increase of the self-fund relating to petroleum, coal and natural gas are encouraging. The Republic of Korea is not attached at the international power net. Therefore, the Republic of Korea highly is susceptible according to energy crisis. The elevated dependence from other countries will exist furthermore. The Republic of Korea should expend its activities relating to foreign affairs and the large oil producers

Malaria remains endemic in 21 countries of the American continent with an estimated 427,000 cases per year. Approximately 10% of these occur in the Mesoamerican and Caribbean regions. During the last decade, malaria transmission in Mesoamerica showed a decrease of ~85%; whereas, in the Caribbean region, Hispaniola (comprising the Dominican Republic [DR] and Haiti) presented an overall rise in malaria transmission, primarily due to a steady increase in Haiti, while DR experienced a significant transmission decrease in this period. The significant malaria reduction observed recently in the region prompted the launch of an initiative for Malaria Elimination in Mesoamerica and Hispaniola (EMMIE) with the active involvement of the National Malaria Control Programs (NMCPs) of nine countries, the Regional Coordination Mechanism (RCM) for Mesoamerica, and the Council of Health Ministries of Central America and Dominican Republic (COMISCA). The EMMIE initiative is supported by the Global Fund for Aids, Tuberculosis and Malaria (GFATM) with active participation of multiple partners including Ministries of Health, bilateral and multilateral agencies, as well as research centers. EMMIE’s main goal is to achieve elimination of malaria transmission in the region by 2020. Here we discuss the prospects, challenges, and research needs associated with this initiative that, if successful, could represent a paradigm for other malaria-affected regions. PMID:25973753

Heinrich Dieter "Dick" Holland, who died on 21 May 2012, was responsible for major advances across several fields of geochemistry. He was born on 27 May 1927 and died just short of his 85th birthday. How Dick became a geochemist is an interesting story in itself. I first met Dick when we shared an office as graduate students at Columbia University in New York. He had attended Princeton University in New Jersey and graduated in 1946 with a chemistry major. He had arrived in the United States with his family from Germany in 1940. The family was of Jewish origin, and although Dick and his relatives were not strict practitioners, their fate in Hitler's Germany, dictated by the family's ancestry, would have been undesirable. Dick and his brother first went to England in 1939 to escape the future horrors that were sure to await them if they had remained in Germany. After their parents escaped to the Dominican Republic, Dick and his brother joined them there. With the help of friends, the family came to the United States from the Dominican Republic in 1940 (it was not unusual for immigrants to first come to a landing spot in the western hemisphere prior to admission to the United States).

Full Text Available ABSTRACT This article approaches the preparation of the teachers of the primary level to face the negative attitudes of the pupils towards mathematics, as a component of the affective domain. Prior studies in the area of affective domain of mathematics and his influence in pupils’learning were documented, as well as the role of the teachers to attend to consider affective problems associated to learning. Dominican Republic is one of the countries with the lowest scores in mathematics at the primary level in Latin America and the Caribbean. To find out whether the initial training of teachers at the primary level of the Dominican Republic is considering mathematics teacher education, with an emphasis in mathematics affective education, a diagnosis was made at "Salomé Ureña" College of Education of Santo Domingo. Several indicators and instruments were used for data collection. The main techniques used in the diagnosis were document reviewing, text commenting, written test, questionnaire, interviews and supervising teachers’ performance. The initial findingwascompared to the indicators to conclude thatteachers needs some training to solve the contradiction between the demands on teachers in the field of affective education mathematics and current college of education curriculum limitations.

The contamination of drinking water resources by toxic metals is a major problem in many parts of the world, particularly in dense populated areas of developing countries that lack wastewater treatment facilities. The present study characterizes the recent evolution with time of some contaminants deposited in the Congo River and Lake Ma Vallée, both located in the vicinity of the large city of Kinshasa, capital of Democratic Republic of Congo (DRC). Physicochemical parameters including grain size distribution, organic matter and trace element concentrations were measured in sediment cores sampled from Congo River (n = 3) and Lake Ma Vallée (n = 2). The maximum concentration of trace elements in sediment profiles was found in the samples from the sites of Pool Malebo, with the values of 107.2, 111.7, 88.6, 39.3, 15.4, 6.1 and 4.7 mg kg(-1) for Cr, Ni, Zn, Cu, Pb, As and Hg, respectively. This site, which is characterized by intense human activities, is especially well known for the construction of numerous boats that are used for regular navigation on Congo River. Concerning Lake Ma Vallée, the concentration of all metals are generally low, with maximum values of 26.3, 53.6, 16.1, 15.3, 6.5 and 1.8 mg kg(-1) for Cr, Ni, Zn, Cu, Pb and As, respectively. However, the comparison of the metal profiles retrieved from the different sampled cores also reveals specific variations. The results of this study point out the sediment pollution by toxic metals in the Congo River Basin. This research presents useful tools for the evaluation of sediment contamination of river-reservoir systems.

Paragenetic evolution of reservoir facies, Middle Triassic Halfway Formation, PeeJay Field, northeastern British Columbia: controls on reservoir quality

Because of the obvious importance of reservoir quality to reservoir performance, diagenetic controls on reservoir quality of Middle Triassic reservoir facies are investigated by comparing two reservoir lithofacies. The implications of porosity structure on the efficiency of primary and secondary hydrocarbon recovery are also assessed. Halfway reservoir facies are composed of bioclastic grainstones (lithofacies G) and litharenites/sublitharenites (lithofacies H), both of which are interpreted as tidal inlet fills. Although paragenetic evolution was similar for the two reservoir facies, subtle differences in reservoir quality are discernible. These are controlled by sedimentary structures, porosity type, grain constituents, and degree of cementation. Reservoir quality in lithofacies G is a function of connectivity of the pore network. In lithofacies H, secondary granular porosity creates a more homogeneous interconnected pore system, wide pore throats and low aspect ratios. The high porosity and low permeability values of the bioclastic grainstones are suspected to cause inefficient flushing of hydrocarbons during waterflooding. However, it is suggested that recovery may be enhanced by induced hydraulic fracturing and acidization of lower permeability calcareous cemented zones. 52 refs., 15 figs.

This reservoir is modeled after the inferred properties of the hydrate deposit at the Prudhoe Bay L-106 site. The included sensitivity variables were hydrate saturation, pressure (depth), temperature, bottom-hole pressure of the production well, free water saturation, intrinsic rock permeability, and porosity. A two-level (L=2) Plackett-Burman experimental design was used to study the relative effects of these factors. The measured variable was the discounted cumulative gas production. The discount rate chosen was 15%, resulting in the gas contribution to the net present value of a reservoir. Eight different designs were developed for conducting sensitivity analysis and the effects of the parameters on the real and discounted production rates will be discussed. The breakeven price in various cases and the dependence of the breakeven price on the production parameters is given in the paper. As expected, initial reservoir temperature has the strongest positive effect on the productivity of a hydrate deposit and the bottom-hole pressure in the production well has the strongest negative dependence. Also resulting in a positive correlation is the intrinsic permeability and the initial free water of the formation. Negative effects were found for initial hydrate saturation (at saturations greater than 50% of the pore space) and the reservoir porosity. These negative effects are related to the available sensible heat of the reservoir, with decreasing productivity due to decreasing available sensible heat. Finally, we conclude that for the base case reservoir, the break-even price (BEP

3D static reservoir modeling of the Bahariya reservoirs using seismic and wells data can be a relevant part of an overall strategy for the oilfields development in South Umbarka area (Western Desert, Egypt). The seismic data is used to build the 3D grid, including fault sticks for the fault modeling, and horizon interpretations and surfaces for horizon modeling. The 3D grid is the digital representation of the structural geology of Bahariya Formation. When we got a reasonably accurate representation, we fill the 3D grid with facies and petrophysical properties to simulate it, to gain a more precise understanding of the reservoir properties behavior. Sequential Indicator Simulation (SIS) and Sequential Gaussian Simulation (SGS) techniques are the stochastic algorithms used to spatially distribute discrete reservoir properties (facies) and continuous reservoir properties (shale volume, porosity, and water saturation) respectively within the created 3D grid throughout property modeling. The structural model of Bahariya Formation exhibits the trapping mechanism which is a fault assisted anticlinal closure trending NW-SE. This major fault breaks the reservoirs into two major fault blocks (North Block and South Block). Petrophysical models classified Lower Bahariya reservoir as a moderate to good reservoir rather than Upper Bahariya reservoir in terms of facies, with good porosity and permeability, low water saturation, and moderate net to gross. The Original Oil In Place (OOIP) values of modeled Bahariya reservoirs show hydrocarbon accumulation in economic quantity, considering the high structural dips at the central part of South Umbarka area. The powerful of 3D static modeling technique has provided a considerable insight into the future prediction of Bahariya reservoirs performance and production behavior.

Deriving Area-storage Curves of Global Reservoirs

Basic information including capacity, dam height, and largest water area on global reservoirs and dams is well documented in databases such as GRanD (Global Reservoirs and Dams), ICOLD (International Commission on Large Dams). However, though playing a critical role in estimating reservoir storage variations from remote sensing or hydrological models, area-storage (or elevation-storage) curves of reservoirs are not publicly shared. In this paper, we combine Landsat surface water extent, 1 arc-minute global relief model (ETOPO1) and GRanD database to derive area-storage curves of global reservoirs whose area is larger than 1 km2 (6,000 more reservoirs are included). First, the coverage polygon of each reservoir in GRanD is extended to where water was detected by Landsat during 1985-2015. Second, elevation of each pixel in the reservoir is extracted from resampled 30-meter ETOPO1, and then relative depth and frequency of each depth value is calculated. Third, cumulative storage is calculated with increasing water area by every one percent of reservoir coverage area and then the uncalibrated area-storage curve is obtained. Finally, the area-storage curve is linearly calibrated by the ratio of calculated capacity over reported capacity in GRanD. The derived curves are compared with in-situ reservoir data collected in Great Plains Region in US, and the results show that in-situ records are well captured by the derived curves even in relative small reservoirs (several square kilometers). The new derived area-storage curves have the potential to be employed in global monitoring or modelling of reservoirs storage and area variations.

Stratigraphic geothermal reservoirs at 3 – 4 km depth in high heat-flow basins are capable of sustaining 100 MW-scale power plants at about 10 c/kWh. This paper examines the impacts on the levelized cost of electricity (LCOE) of reservoir depth and temperature, reservoir productivity, and drillhole/casing options. For a reservoir at 3 km depth with a moderate productivity index by hydrothermal reservoir standards (about 50 L/s/MPa, 5.6 gpm/psi), an LCOE of 10c/kWh requires the reservoir to be at about 200°C. This is the upper temperature limit for pumps. The calculations assume standard hydrothermal drilling costs, with the production interval completed with a 7 inch liner in an 8.5 inch hole. If a reservoir at 4 km depth has excellent permeability characteristics with a productivity index of 100 L/s/MPa (11.3 gpm/psi), then the LCOE is about 11 c/kWh assuming the temperature decline rate with development is not excessive (< 1%/y, with first thermal breakthrough delayed by about 10 years). Completing wells with modest horizontal legs (e.g. several hundred meters) may be important for improving well productivity because of the naturally high, sub-horizontal permeability in this type of reservoir. Reducing the injector/producer well ratio may also be cost-effective if the injectors are drilled as larger holes.

Estimating Western U.S. Reservoir Sedimentation

Bensching, L.; Livneh, B.; Greimann, B. P.

2017-12-01

Reservoir sedimentation is a long-term problem for water management across the Western U.S. Observations of sedimentation are limited to reservoir surveys that are costly and infrequent, with many reservoirs having only two or fewer surveys. This work aims to apply a recently developed ensemble of sediment algorithms to estimate reservoir sedimentation over several western U.S. reservoirs. The sediment algorithms include empirical, conceptual, stochastic, and processes based approaches and are coupled with a hydrologic modeling framework. Preliminary results showed that the more complex and processed based algorithms performed better in predicting high sediment flux values and in a basin transferability experiment. However, more testing and validation is required to confirm sediment model skill. This work is carried out in partnership with the Bureau of Reclamation with the goal of evaluating the viability of reservoir sediment yield prediction across the western U.S. using a multi-algorithm approach. Simulations of streamflow and sediment fluxes are validated against observed discharges, as well as a Reservoir Sedimentation Information database that is being developed by the US Army Corps of Engineers. Specific goals of this research include (i) quantifying whether inter-algorithm differences consistently capture observational variability; (ii) identifying whether certain categories of models consistently produce the best results, (iii) assessing the expected sedimentation life-span of several western U.S. reservoirs through long-term simulations.

Safeguards in the Slovak Republic

The former Czechoslovakia acceded to the Non-Proliferation Treaty in 1968. Based on requirements of the Safeguard Agreement the State System of Accounting for and Control of nuclear material has been established. After dissolution of Czechoslovakia the Slovak Republic succeeded to the Safeguards Agreement. As a regulator the Nuclear Regulatory Authority of the Slovak Republic (UJD) has been constituted. After European Union (EU) accession EU legislation became valid in the Slovak republic. Atomic Law No. 541/2004 Coll. on Peaceful Use of Nuclear Energy adopts this legislation. In the frame of strengthening the IAEA safeguards an implementation of the Protocol Additional became actual. The Protocol Additional was signed by the government of the Slovak Republic in September 1999. On 1 December 2005 safeguards agreement INFCIRC/193 including the relevant Additional Protocol entered into force. As an instrument supporting non-proliferation of nuclear weapons a control of export/import of nuclear material, nuclear related and dual-use material following the EC regulation 428/2009 of 5 May 2009 setting up a Community regime for the control of exports, transfer, brokering and transit of dual use items. The execution of accountancy and control of nuclear material inspection activities has been considerably influenced by the implementation of integrated safeguards, implemented in the Slovak Republic on 1 September 2009. The aim of mentioned integrated safeguards regime is to decrease the amount and difficulty of inspections. At the same time the possibility of accountancy and control of nuclear material inspections announced 24 hours in advance took effect. The execution of Protocol Additional inspections remains the same. Additionally to international safeguards system UJD has kept the national safeguards system which observes all nuclear material on the territory of the Slovak Republic. The government of the Slovak Republic plays active role within activities of the NSG

Costus spicatus Sw. (Costaceae) is a prominent medicinal herb used by Dominicans in the Dominican Republic and the United States for the treatment of diabetes, a growing epidemic in the Hispanic community. An ethnobotanical survey of the Dominican community in New York City revealed the popular use of a tea from the insulina plant to treat hyperglycemia. Insulina was identified as Costus spicatus. We tested the ability of a tea made from the leaves of Costus spicatus to alter glucose homeostasis in C57BLKS/J (KS) db/db mice, a model of obesity-induced hyperglycemia with progressive beta cell depletion. From 6 to 16 weeks of age, Experimental and Control animals (n=6/5) were given ad lib access to Costus spicatus tea or water, respectively. Weight gain and progression of hyperglycemia and insulinopenia between the Experimental and Control groups were statistically indistinguishable. There was no difference between groups in average fed or fasting glucose and insulin concentrations. Intraperitoneal (IP) insulin tolerance testing after the 10-week study period showed that Costus spicatus tea consumption did not alter insulin sensitivity. These data suggest that at the dose given, tea made from Costus spicatus leaves had no efficacy in the treatment of obesity-induced hyperglycemia. More investigation is needed to more fully explore dosages and the possible utility and biological activity of this common Dominican herbal remedy for the treatment of type 2 diabetes mellitus.

Anthropogenic activities, e.g., reservoir operation, may alter the characteristics of Flood Frequency Curve (FFC) and challenge the basic assumption of stationarity used in flood frequency analysis. This paper presents a combined data-modeling analysis of the nonlinear filtering effects of reservoirs on the FFCs over the contiguous United States. A dimensionless Reservoir Impact Index (RII), defined as the total upstream reservoir storage capacity normalized by the annual streamflow volume, is used to quantify reservoir regulation effects. Analyses are performed for 388 river stations with an average record length of 50 years. The first two moments of the FFC, mean annual maximum flood (MAF) and coefficient of variations (CV), are calculated for the pre- and post-dam periods and compared to elucidate the reservoir regulation effects as a function of RII. It is found that MAF generally decreases with increasing RII but stabilizes when RII exceeds a threshold value, and CV increases with RII until a threshold value beyond which CV decreases with RII. The processes underlying the nonlinear threshold behavior of MAF and CV are investigated using three reservoir models with different levels of complexity. All models capture the non-linear relationships of MAF and CV with RII, suggesting that the basic flood control function of reservoirs is key to the non-linear relationships. The relative roles of reservoir storage capacity, operation objectives, available storage prior to a flood event, and reservoir inflow pattern are systematically investigated. Our findings may help improve flood-risk assessment and mitigation in regulated river systems at the regional scale.

Using reservoir engineering data to solve geological ambiguities : a case study of one of the Iranian carbonate reservoirs

Kord, S. [National Iranian South Oil Co. (Iran, Islamic Republic of)

A fractured carbonate reservoir in southwest Iran was studied with reference to reserve estimation, risk analysis, material balance and recovery factor. The 40 km long and 4 km wide reservoir consists of 2 parts with crest depths of 3780 and 3749 mss respectively. The eastern part is smaller and more productive than the western part which has high water saturation and absolutely no production. Economic production from the reservoir began in 1977. By 2004, the cumulative production had reached 12.064 MMSTB. Of the 6 wells drilled, only 2 wells in the eastern part are productive. This study addressed the main uncertainty of whether the 2 parts of the reservoir are sealed or not. The reservoir is under-saturated but the current pressure is near saturation pressure. The reservoir is divided into the following 4 zones: zones 1 and 2 are productive and consist mainly of carbonate rocks; zone 3 has thin beds of sand and shale; and, zone 4 consists of layers of carbonate, shale, marn, and dolomite. Although there are no faults, mud loss suggests that the reservoir has hairline fractures. Oil in place and reserves were estimated for both parts based on calculated reservoir engineering parameters. Material balance calculations were then performed to analyze and simulate the reservoir. The communication between the 2 parts of the reservoir were examined according to core analysis, rock type, fluid characterization, pressure analysis, water-oil contacts, production history and petrophysical evaluations. The porosity was found to be the same in both parts, but the water saturation and net to gross ratios were different between the eastern and western parts. The petrophysical evaluation revealed that there is no communication between the two parts of the reservoir. 4 refs., 2 figs., 2 appendices.

Li, Siyue; Zhang, Quanfa

2014-12-01

Substantial greenhouse gas (GHG) emissions from hydropower reservoirs have been of great concerns recently, yet the significant carbon emitters of drawdown area and reservoir downstream (including spillways and turbines as well as river reaches below dams) have not been included in global carbon budget. Here, we revisit GHG emission from hydropower reservoirs by considering reservoir surface area, drawdown zone and reservoir downstream. Our estimates demonstrate around 301.3 Tg carbon dioxide (CO2)/year and 18.7 Tg methane (CH4)/year from global hydroelectric reservoirs, which are much higher than recent observations. The sum of drawdown and downstream emission, which is generally overlooked, represents 42 % CO2 and 67 % CH4 of the total emissions from hydropower reservoirs. Accordingly, the global average emissions from hydropower are estimated to be 92 g CO2/kWh and 5.7 g CH4/kWh. Nonetheless, global hydroelectricity could currently reduce approximate 2,351 Tg CO2eq/year with respect to fuel fossil plant alternative. The new findings show a substantial revision of carbon emission from the global hydropower reservoirs.

Full Text Available Field outcrop observation, drilling core description, thin-section analysis, SEM analysis, and geochemistry, indicate that Dixi area of Carboniferous volcanic rock gas reservoir belongs to the volcanic rock oil reservoir of the authigenic gas reservoir. The source rocks make contact with volcanic rock reservoir directly or by fault, and having the characteristics of near source accumulation. The volcanic rock reservoir rocks mainly consist of acidic rhyolite and dacite, intermediate andesite, basic basalt and volcanic breccia: (1 Acidic rhyolite and dacite reservoirs are developed in the middle-lower part of the structure, have suffered strong denudation effect, and the secondary pores have formed in the weathering and tectonic burial stages, but primary pores are not developed within the early diagenesis stage. Average porosity is only at 8%, and the maximum porosity is at 13.5%, with oil and gas accumulation showing poor performance. (2 Intermediate andesite and basic basalt reservoirs are mainly distributed near the crater, which resembles the size of and suggests a volcanic eruption. Primary pores are formed in the early diagenetic stage, secondary pores developed in weathering and erosion transformation stage, and secondary fractures formed in the tectonic burial stage. The average porosity is at 9.2%, and the maximum porosity is at 21.9%: it is of the high-quality reservoir types in Dixi area. (3 The volcanic breccia reservoir has the same diagenetic features with sedimentary rocks, but also has the same mineral composition with volcanic rock; rigid components can keep the primary porosity without being affected by compaction during the burial process. At the same time, the brittleness of volcanic breccia reservoir makes it easily fracture under the stress; internal fracture was developmental. Volcanic breccia developed in the structural high part and suffered a long-term leaching effect. The original pore-fracture combination also made

Full Text Available Pre-basic seed potato material is used for basic seed (elite and certified seed potato production. At this moment all basic seed material is imported into Republic of Serbia and Republic of Srpska, despite the fact that the method of in vitro tissue culture production of virus-free seed potato has been developed in both countries and there is a continuous demand for pre-basic and basic seed potato. Current total production is significantly lower than actual requirements. In the 80s and 90s of the previous century two modern facilities for production of virus-free seed potato and certified seed were built in Sokolac (Republic of Srpska and Guča (Republic of Serbia. Although facilities were well-equipped, seed potato production was permanently ceased in 2000. The presence of high infection pressure dominated by potato virus Y is shown in the Republic of Serbia and the Republic of Srpska. This paper gives an overview of pre-basic seed potato material production in both countries over the last two decades.

Colorectal cancer is the second most common cancer among Latinos, but a lower percentage of Latinos are screened than Whites and Blacks. Along with recognized economic barriers, differences in knowledge and perceptions might impede colorectal screening among Latinos. We conducted 147 individual, qualitative interviews with Dominicans and Puerto Ricans in the northeastern United States to explore their explanatory models for colorectal cancer and screening barriers. Many participants had not previously heard of colorectal cancer. The most commonly mentioned cause of colorectal cancer was anal sex. Also considered risks were "bad food," digestion leading to constipation, and strained bowel movements. Screening barriers included stigma, misperceptions, embarrassment, and machismo. Progress toward increasing colorectal cancer screening requires normalization of this screening among Latinos. Higher patient familiarity, along with improved physician counseling and referral, might contribute to reducing stigma and other barriers, and to enhancing knowledge and Latino community support of colorectal cancer screening.

The Coupling Effect of Rainfall and Reservoir Water Level Decline on the Baijiabao Landslide in the Three Gorges Reservoir Area, China

Directory of Open Access Journals (Sweden)

2017-01-01

Full Text Available Rainfall and reservoir level fluctuation are two of the main factors contributing to reservoir landslides. However, in China’s Three Gorges Reservoir Area, when the reservoir water level fluctuates significantly, it comes at a time of abundant rainfall, which makes it difficult to distinguish which factor dominates the deformation of the landslide. This study focuses on how rainfall and reservoir water level decline affect the seepage and displacement field of Baijiabao landslide spatially and temporally during drawdown of reservoir water level in the Three Gorges Reservoir Area, thus exploring its movement mechanism. The monitoring data of the landslide in the past 10 years were analyzed, and the correlation between rainfall, reservoir water level decline, and landslide displacement was clarified. By the numerical simulation method, the deformation evolution mechanism of this landslide during drawdown of reservoir water level was revealed, respectively, under three conditions, namely, rainfall, reservoir water level decline, and coupling of the above two conditions. The results showed that the deformation of the Baijiabao landslide was the coupling effect of rainfall and reservoir water level decline, while the latter effect is more pronounced.

In this paper, activity concentrations of radiocesium in mushrooms from various locations in the Czech Republic and the Slovak Republic in the years 2000-2004 are presented. Summary reports of Czech regulatory bodies have judged the average activity concentrations in mushrooms to be remarkably below the maximum permissible level of contamination. However, there are certain regions where radiocesium activities have approached the maximum permissible level for contamination of basic foodstuff. For example, the highest activity concentration of (137)Cs measured by gamma-spectrometry was 2,263 Bq kg(-1) (on a dry mass basis), in Xerocomus badius from Staré Ransko (a locality in the Czech-Moravian Highlands, Czech Republic). The highest activity concentration of (137)Cs measured in Slovakia was 966 Bq kg(-1) (on a dry mass basis), for Suillus luteus from Senica. For comparison, the corresponding activity concentration in a sample taken within the 30 km zone around Chernobyl was measured to be 6,000 Bq kg(-1) (on a dry mass basis). Our results have also demonstrated remarkably lower activity concentrations of (137)Cs in Slovakia compared to those in the Czech Republic.

The aim of this study was to assess the contamination level of aquatic ecosystems of the Oslava and the Jihlava Rivers, and of the Nove Mlyny Water Reservoir, situated in the South Moravian Region (Czech Republic), by residues of selected veterinary pharmaceuticals. We isolated and determined 10 sulfonamide antibiotics in samples of surface water and bottom sediments using optimized analytical methods. A representative number of sampling sites in the entire basin of selected waters were chosen. Samples were collected particularly near the larger cities in order to assess their possible impact to the aquatic ecosystems. Extraction, pre-concentration and purification of samples were performed using optimized methods of solid phase extraction and pressurized solvent extraction. Final identification and quantification were carried out by high-performance liquid chromatography coupled with diode array detector. The concentration of sulfonamides in water samples were all under the limit of detection. Regarding sediment samples, sulfadimidine was found at most sampling sites; its highest values were recorded in the Jihlava River (up to 979.8 µg.kg(-1) dry matter). Other frequently detected sulfonamides were sulfamethoxazole and sulfamerazine. Most other sulfonamides were under the limit of detection or limit of quantification. Monitoring of antibiotic residues in the environment, especially in the aquatic ecosystem, is a current topic due to the growing worldwide use in both human and veterinary medicine. According to obtained results, we document the pollution of selected rivers and water reservoir by particular sulfonamides which basically reflects their application in veterinary medicine.

Mathematical and field analysis of longitudinal reservoir infill

In reservoirs, severe problems are caused by infilled sediment deposits. In long term, the sediment accumulation reduces the capacity of reservoir storage and flood control benefits. In the short term, the sediment deposits influence the intakes of water-supply and hydroelectricity generation. For the management of reservoir, it is important to understand the deposition process and then to predict the sedimentation in reservoir. To investigate the behaviors of sediment deposits, we propose a one-dimensional simplified theory derived by the Exner equation to predict the longitudinal sedimentation distribution in idealized reservoirs. The theory models the reservoir infill geomorphic actions for three scenarios: delta progradation, near-dam bottom deposition, and final infill. These yield three kinds of self-similar analytical solutions for the reservoir bed profiles, under different boundary conditions. Three analytical solutions are composed by error function, complementary error function, and imaginary error function, respectively. The theory is also computed by finite volume method to test the analytical solutions. The theoretical and numerical predictions are in good agreement with one-dimensional small-scale laboratory experiment. As the theory is simple to apply with analytical solutions and numerical computation, we propose some applications to simulate the long-profile evolution of field reservoirs and focus on the infill sediment deposit volume resulting the uplift of near-dam bottom elevation. These field reservoirs introduced here are Wushe Reservoir, Tsengwen Reservoir, Mudan Reservoir in Taiwan, Lago Dos Bocas in Puerto Rico, and Sakuma Dam in Japan.

Phytoplankton and water quality of Marathonas drinking-water Reservoir were examined for the first time. During the study period (July-September 2007), phytoplankton composition was indicative of eutrophic conditions although phytoplankton biovolume was low (max. 2.7 mm³ l⁻¹). Phytoplankton was dominated by cyanobacteria and diatoms, whereas desmids and dinoflagellates contributed with lower biovolume values. Changing flushing rate in the reservoir (up to 0.7% of reservoir's water volume per day) driven by water withdrawal and occurring in pulses for a period of 15-25 days was associated with phytoplankton dynamics. Under flushing pulses: (1) biovolume was low and (2) both 'good' quality species and the tolerant to flushing 'nuisance' cyanobacterium Microcystis aeruginosa dominated. According to the Water Framework Directive, the metrics of phytoplankton biovolume and cyanobacterial percentage (%) contribution indicated a moderate ecological water quality. In addition, the total biovolume of cyanobacteria as well as the dominance of the known toxin-producing M. aeruginosa in the reservoir's phytoplankton indicated a potential hazard for human health according to the World Health Organization.

AUTOMATED TECHNIQUE FOR FLOW MEASUREMENTS FROM MARIOTTE RESERVOIRS.

Constantz, Jim; Murphy, Fred

1987-01-01

The mariotte reservoir supplies water at a constant hydraulic pressure by self-regulation of its internal gas pressure. Automated outflow measurements from mariotte reservoirs are generally difficult because of the reservoir's self-regulation mechanism. This paper describes an automated flow meter specifically designed for use with mariotte reservoirs. The flow meter monitors changes in the mariotte reservoir's gas pressure during outflow to determine changes in the reservoir's water level. The flow measurement is performed by attaching a pressure transducer to the top of a mariotte reservoir and monitoring gas pressure changes during outflow with a programmable data logger. The advantages of the new automated flow measurement techniques include: (i) the ability to rapidly record a large range of fluxes without restricting outflow, and (ii) the ability to accurately average the pulsing flow, which commonly occurs during outflow from the mariotte reservoir.

Research and monitoring is essential to assess baseline conditions in reservoirs and their watershed and provide necessary information to guide decision-makers. Erosion and degradation of mountainous areas can lead to gradual aggradation of reservoirs reducing their lifetime. Collected measurements and observations have to be communicated to the managers of the reservoirs so as to achieve a common / comprehensive management of a large watershed and reservoir system. At this point Remote Sensing could help as the remotely sensed data are repeatedly and readily available to the end users. Aliakmon is the longest river in Greece, it's length is about 297 km and the surface of the river basin is 9.210 km2.The flow of the river starts from Northwest of Greece and ends in Thermaikos Gulf. The riverbed is not natural throughout the entire route, because constructed dams restrict water and create artificial lakes, such as lake of Polyfitos, that prevent flooding. This lake is used as reservoir, for covering irrigational water needs and the water is used to produce energy from the hydroelectric plant of Public Power Corporation-PPC. The catchment basin of Polyfitos' reservoir covers an area of 847.76 km2. Soil erosion - degradation in the mountainous watershed of streams of Polyfitos reservoir is taking place. It has been estimated that an annual volume of sediments reaching the reservoir is of the order of 244 m3. Geomatic based techniques are used in processing multiple data of the study area. A data inventory was formulated after the acquisition of topographic maps, compilation of geological and hydro-geological maps, compilation of digital elevation model for the area of interest based on satellite data and available maps. It also includes the acquisition of various hydro-meteorological data when available. On the basis of available maps and satellite data, digital elevation models are used in order to delineate the basic sub-catchments of the Polyfytos basin as well as

SEISMIC DETERMINATION OF RESERVOIR HETEROGENEITY: APPLICATION TO THE CHARACTERIZATION OF HEAVY OIL RESERVOIRS

2005-02-01

The objective of the project was to examine how seismic and geologic data can be used to improve characterization of small-scale heterogeneity and their parameterization in reservoir models. The study focused on West Coalinga Field in California. The project initially attempted to build reservoir models based on different geologic and geophysical data independently using different tools, then to compare the results, and ultimately to integrate them all. We learned, however, that this strategy was impractical. The different data and tools need to be integrated from the beginning because they are all interrelated. This report describes a new approach to geostatistical modeling and presents an integration of geology and geophysics to explain the formation of the complex Coalinga reservoir.

The objectives of this report are three-fold: (1) assess physical, chemical, and biological conditions in the major embayments of Chickamauga Reservoir; (2) compare water quality and biological conditions of embayments with main river locations; and (3) identify any water quality concerns in the study embayments that may warrant further investigation and/or management actions. Embayments are important areas of reservoirs to be considered when assessments are made to support water quality management plans. In general, embayments, because of their smaller size (water surface areas usually less than 1000 acres), shallower morphometry (average depth usually less than 10 feet), and longer detention times (frequently a month or more), exhibit more extreme responses to pollutant loadings and changes in land use than the main river region of the reservoir. Consequently, embayments are often at greater risk of water quality impairments (e.g. nutrient enrichment, filling and siltation, excessive growths of aquatic plants, algal blooms, low dissolved oxygen concentrations, bacteriological contamination, etc.). Much of the secondary beneficial use of reservoirs occurs in embayments (viz. marinas, recreation areas, parks and beaches, residential development, etc.). Typically embayments comprise less than 20 percent of the surface area of a reservoir, but they often receive 50 percent or more of the water-oriented recreational use of the reservoir. This intensive recreational use creates a potential for adverse use impacts if poor water quality and aquatic conditions exist in an embayment.

Schistosomiasis japonica, an endemic, zoonotic tropical parasitic disease caused by Schistosoma japonicum, remains an important public health concern in The People's Republic of China. Unlike other species of Schistosoma, over 40 species of wild and domestic animals can act as reservoir hosts of S. japonicum, which increases the difficulty for the control of this tropical disease. It is widely recognized that domestic animals, particularly water buffaloes and cattle, play an important role in the transmission of S. japonicum. Hence, since the 1950s when The People's Republic of China commenced fight against the disease, the control of animal schistosomiasis has been carried out almost synchronously with that of human schistosomiasis, such that great strides have been made over the past six decades. In this chapter, we review the history and current status of schistosomiasis control in domestic animals in The People's Republic of China. We thoroughly analyse the prevalence of domestic animal schistosomiasis at different stages of schistosomiasis control and the role of different species of domestic animals in transmission of the disease, summarize the control strategies and assess their effectiveness. Furthermore, the challenges ahead are discussed and recommendations for future direction are provided. Copyright © 2016 Elsevier Ltd. All rights reserved.

Reservoir Identification: Parameter Characterization or Feature Classification

Science.gov (United States)

Cao, J.

2017-12-01

The ultimate goal of oil and gas exploration is to find the oil or gas reservoirs with industrial mining value. Therefore, the core task of modern oil and gas exploration is to identify oil or gas reservoirs on the seismic profiles. Traditionally, the reservoir is identify by seismic inversion of a series of physical parameters such as porosity, saturation, permeability, formation pressure, and so on. Due to the heterogeneity of the geological medium, the approximation of the inversion model and the incompleteness and noisy of the data, the inversion results are highly uncertain and must be calibrated or corrected with well data. In areas where there are few wells or no well, reservoir identification based on seismic inversion is high-risk. Reservoir identification is essentially a classification issue. In the identification process, the underground rocks are divided into reservoirs with industrial mining value and host rocks with non-industrial mining value. In addition to the traditional physical parameters classification, the classification may be achieved using one or a few comprehensive features. By introducing the concept of seismic-print, we have developed a new reservoir identification method based on seismic-print analysis. Furthermore, we explore the possibility to use deep leaning to discover the seismic-print characteristics of oil and gas reservoirs. Preliminary experiments have shown that the deep learning of seismic data could distinguish gas reservoirs from host rocks. The combination of both seismic-print analysis and seismic deep learning is expected to be a more robust reservoir identification method. The work was supported by NSFC under grant No. 41430323 and No. U1562219, and the National Key Research and Development Program under Grant No. 2016YFC0601

An environmental data base for all Hydro-Quebec reservoirs

1988-01-01

Hydro-Quebec has created two management positions specifically for reservoirs, namely Reservoir Ecology Advisor and Reservoir Management Advisor. To assist management decisions, a means was required of bringing together all existing environmental information for each reservoir operated by Hydro-Quebec, including storage reservoirs, auxiliary reservoirs and forebays. A relational database using Reflex software was developed on a network of Macintosh computers. The database contains five blocks of information: general information, and physical, physiochemical, biologic and socioeconomic characteristics for each reservoir. Data will be collected on over 100 sites, and the tool will form the basis for developing a medium-range study program on reservoir ecology. The program must take into account the physical, biological and socioeconomic aspects of the environment, as well as the concerns of management personnel operating the reservoirs, the local population, reservoir users, and various government departments. 2 figs

Ecological operation for Three Gorges Reservoir

Directory of Open Access Journals (Sweden)

Wen-xian Guo

2011-06-01

Full Text Available The traditional operation of the Three Gorges Reservoir has mainly focused on water for flood control, power generation, navigation, water supply, and recreation, and given less attention to the negative impacts of reservoir operation on the river ecosystem. In order to reduce the negative influence of reservoir operation, ecological operation of the reservoir should be studied with a focus on maintaining a healthy river ecosystem. This study considered ecological operation targets, including maintaining the river environmental flow and protecting the spawning and reproduction of the Chinese sturgeon and four major Chinese carps. Using flow data from 1900 to 2006 at the Yichang gauging station as the control station data for the Yangtze River, the minimal and optimal river environmental flows were analyzed, and eco-hydrological targets for the Chinese sturgeon and four major Chinese carps in the Yangtze River were calculated. This paper proposes a reservoir ecological operation model, which comprehensively considers flood control, power generation, navigation, and the ecological environment. Three typical periods, wet, normal, and dry years, were selected, and the particle swarm optimization algorithm was used to analyze the model. The results show that ecological operation modes have different effects on the economic benefit of the hydropower station, and the reservoir ecological operation model can simulate the flood pulse for the requirements of spawning of the Chinese sturgeon and four major Chinese carps. According to the results, by adopting a suitable re-operation scheme, the hydropower benefit of the reservoir will not decrease dramatically while the ecological demand is met. The results provide a reference for designing reasonable operation schemes for the Three Gorges Reservoir.

Functional age as an indicator of reservoir senescence

Science.gov (United States)

Miranda, Leandro E.; Krogman, R. M.

2015-01-01

It has been conjectured that reservoirs differ in the rate at which they manifest senescence, but no attempt has been made to find an indicator of senescence that performs better than chronological age. We assembled an indicator of functional age by creating a multimetric scale consisting of 10 metrics descriptive of reservoir environments that were expected to change directionally with reservoir senescence. In a sample of 1,022 U.S. reservoirs, chronological age was not correlated with functional age. Functional age was directly related to percentage of cultivated land in the catchment and inversely related to reservoir depth. Moreover, aspects of reservoir fishing quality and fish population characteristics were related to functional age. A multimetric scale to indicate reservoir functional age presents the possibility for management intervention from multiple angles. If a reservoir is functionally aging at an accelerated rate, action may be taken to remedy the conditions contributing most to functional age. Intervention to reduce scores of selected metrics in the scale can potentially reduce the rate of senescence and increase the life expectancy of the reservoir. This leads to the intriguing implication that steps can be taken to reduce functional age and actually make the reservoir grow younger.

Upper Hiwassee River Basin reservoirs 1989 water quality assessment

International Nuclear Information System (INIS)

Fehring, J.P.

1991-08-01

The water in the Upper Hiwassee River Basin is slightly acidic and low in conductivity. The four major reservoirs in the Upper Hiwassee River Basin (Apalachia, Hiwassee, Chatuge, and Nottely) are not threatened by acidity, although Nottely Reservoir has more sulfates than the other reservoirs. Nottely also has the highest organic and nutrient concentrations of the four reservoirs. This results in Nottely having the poorest water clarity and the most algal productivity, although clarity as measured by color and secchi depths does not indicate any problem with most water use. However, chlorophyll concentrations indicate taste and odor problems would be likely if the upstream end of Nottely Reservoir were used for domestic water supply. Hiwassee Reservoir is clearer and has less organic and nutrient loading than either of the two upstream reservoirs. All four reservoirs have sufficient algal activity to produce supersaturated dissolved oxygen conditions and relatively high pH values at the surface. All four reservoirs are thermally stratified during the summer, and all but Apalachia have bottom waters depleted in oxygen. The very short residence time of Apalachia Reservoir, less than ten days as compared to over 100 days for the other three reservoirs, results in it being more riverine than the other three reservoirs. Hiwassee Reservoir actually develops three distinct water temperature strata due to the location of the turbine intake. The water quality of all of the reservoirs supports designated uses, but water quality complaints are being received regarding both Chatuge and Nottely Reservoirs and their tailwaters
