    Farm workers are at a very high risk of occupational diseases due to exposure to pesticides resulting from inadequate education, training and safety systems. The farm worker spends a lot of time exposed to these harmful agrochemicals. Numerous acute cases with symptoms typical of agrochemical exposure were reported from the commercial farms. We assessed the health effects of agrochemicals in farm workers in commercial farms of Kwekwe District (Zimbabwe), in 2006. An analytical cross sectional study was conducted amongst a sample of 246 farm workers who handled agrochemicals when discharging their duties in the commercial farms. Plasma cholinesterase activity in blood specimens obtained from farm workers was measured using spectrophotometry to establish levels of poisoning by organophosphate and/or carbamates. Information on the knowledge, attitudes and practices of farm workers on agrochemicals use was collected using a pre-tested interviewer administered questionnaire. Bivariate and multivariate analyses were conducted to determine factors that were associated with abnormal cholinesterase activity. The prevalence of organophosphate poisoning, indicated by cholinesterase activity of 75% or less, was 24.1%. The median period of exposure to agrochemicals was 3 years (Q(1):=1 year, Q(3):=7 years). Ninety eight (41.5%) farm workers knew the triangle colour code for the most dangerous agrochemicals. Not being provided with personal protective equipment (OR 2.00; 95% CI: 1.07 - 3.68) and lack of knowledge of the triangle colour code for most dangerous agrochemicals (OR 2.02; 95% CI: 1.02 - 4.03) were significantly associated with abnormal cholinesterase activity. There was organophosphate poisoning in the commercial farms. Factors that were significantly associated with the poisoning were lack of protective clothing and lack of knowledge of the triangle colour code for most dangerous agrochemicals. We recommended intensive health education and training of farm workers on

    The goal of this project was to protect children while parents work in agriculture by improving off-farm services for children of migrant and seasonal farm workers. Large agricultural enterprises have policies forbidding children in the worksite. At the same time, their employees, who are trying to generate income, seek as many work hours as possible but often lack viable options for childcare services. As employers strive to increase their labor pool, and workers seek off-farm childcare, there is mutual interest in improving access to childcare services in agricultural regions dependent on large numbers of full-time and seasonal workers. This report describes the employers' perspectives on childcare needs of hired farm workers' families and their barriers and motivators to facilitating off-farm childcare services. Using descriptive survey research methodology, data were collected from a convenience sample of 102 agribusiness owners and Human Resource directors attending an agricultural conference regarding labor laws or personnel management. Results revealed significant differences for those companies employing more than 25 workers compared to their counterparts. Primary motivators for offering childcare as an employment benefit were improved employee morale, enhanced company reputation, and a more stable workforce. A major barrier was that half of large-scale enterprises lack guidance on how to provide childcare options for their workers. Survey results are being used to facilitate collaboration among employers, farm workers, and childcare providers to offer a safe, nurturing environment for children while their parents work in agriculture.

    Full Text Available The aim of this study was to analyze feeding practices in Costa Rica’s dairy farms and their influence on greenhouse gas emissions (GHG. Methane (CH4, nitrous oxide (N2O, and income over feed cost (IOFC were evaluated. This study was carried out at 104 dairy farms, which were distributed within a range of altitude from 1000 to 2400 meters above sea level. Using cluster analysis based on type of feed, grazing period, areas of forage and pastures; four feeding strategies were identified, which included different proportions of feed categories in daily rations. Emissions expressed as carbon dioxide equivalent per kilo of fat and protein corrected milk (CO2eq/FPCM were higher for forage feeding strategies and lower for farms found in higher altitudes. Concentrate feed accounted for the higher cost in all feeding strategies, and represented more than 50% in the intensive concentrate based production system, whereas the costs of fertilizers were higher in pasture based feeding strategies. Income from milk sales was higher for the concentrate based feeding strategy. However, IOFC was the same for all feeding strategies in spite of the large differences in daily milk production. Feeding strategies influenced GHG emissions and feeding costs. Feeding strategies associated with lower GHG emissions within the farm were more dependent from external inputs.

    2009-01-01

    Although listed in some publications as an activity associated with silica (quartz) exposure, agriculture is not widely recognized as an industry with a potential for silica associated diseases. Because so many people work in agriculture; and because silica exposure and silicosis are associated with serious diseases such as tuberculosis (TB), particular in those immunological compromised by the Human immunodeficiency virus (HIV), silica exposure in agriculture is potentially very important. But in South Africa (SA) very little is known about silica exposure in this industry. The objectives of this project are: (a) to measure inhalable and respirable dust and its quartz content on two typical sandy soil farms in the Free State province of SA for all major tasks done on the farms; and (b) to characterise the mineralogy soil type of these farms. Two typical farms in the sandy soil region of the Free State province were studied. The potential health effects faced by these farm workers from exposure to respirable crystalline silica are discussed.

    At an HIV clinic in the Limpopo province of South Africa, chart reviews revealed long delays in addressing abnormal Pap smears, difficulty in referrals, poor quality and lost results, and increasing cases of cervical cancer. To address these barriers, a "see and treat" approach to screening was proposed. The objective was to integrate this method into current HIV care offered by local providers and to obtain demographic and risk factor data for use in future educational and intervention programs in the region. A cross sectional study of HIV farm workers and at-risk sex workers attending an HIV clinic was performed with visual inspection with acetic acid (VIA). Those with positive screens were offered cryotherapy. Clinic charts were reviewed retrospectively for Pap smear results for the previous year at the time of program initiation and at 12 and 18 months post-program. A total of 403 participants consented and underwent screening with VIA (306 Farm workers and 97 sex workers participated). 83.9% of participants (32.9% sex workers and 100% farm workers) were HIV +. VIA was positive in 30.5% of participants, necessitating cryotherapy. There was no significant difference in VIA positivity between HIV + farm workers and sex workers. There was a positive correlation between Pap smears and VIAs results. We demonstrate successful integration of cervical cancer screening using VIA for HIV + farm workers and sex workers into an existing HIV treatment and prevention clinic in rural South Africa, addressing and treating abnormal results promptly.

    2007-09-01

    The purpose of this exploratory descriptive study was to examine a process model of the nervios experience of 30 Mexican seasonal farm workers. Focused interviews were conducted in Spanish to determine the workers' perspectives on their experiences of nervios while residing in rural, southwest Ontario. Data for analysis originated from variables created to represent key themes that had emerged from open coding of the interviews. Simultaneous entry, multiple regression analyses revealed that provocation, control salience, and cognitive sensory motor distress directly explained 67.2% of the variation in worker expressions of negative affectivity. The combination fear, feeling trapped, and giving in mediated the relationship of provocation, control salience and cognitive sensory motor distress to expressions of negative affectivity (R(2) = 88.1%). Control salience and its dampening effect on other elements of the nervios experience, however, appeared to be key to whether subjects experienced negative reactions to being provoked or distressed. This evidence points to nervios being a powerful, holistic idiom of distress with at least six variables contributing to its affective negativity. This information is important to our understanding of how nervios unfolds and for accurate specification of a nervios model for clinical practice and research. It also sets the stage for improved therapeutic alliances with nervios sufferers, and social action to reduce factors that provoke nervios.

    Full Text Available Abstract Introduction: Flexibility is an essential component of physical aptitude that reduces the incidence of muscle distention and improves movement efficiency and posture. Objective: To analyze posterior chain flexibility and lower back pain (LBP in farm workers from a city in western Santa Catarina state, Brazil. Methods: Quantitative and cross-sectional study conducted with 185 rural workers, average age of 44.24 (±10.83 years. The Rural Worker Health Questionnaire, containing individual issues related to work; sit and reach box, goniometer, visual analog scale (VAS and Oswestry and Roland-Morris questionnaires were used to evaluate posterior chain flexibility, hamstring muscle length, pain and lumbar spine dysfunction, respectively. Flexibility was compared with the degree of dysfunction using one-way ANOVA followed by the Bonferroni post hoc test. Results: 181 (97.8% workers reported LBP symptoms: 100% of the women and 95.2% of the men. The average Oswestry score was 7.09 (±8.25, Roland-Morris 1.22 (±1.63, and VAS 5.81 (±2.5. Average flexibility by the sit and reach test (SRT was 23.91cm (±18.81; straight leg raise (SLR, 66° (±11.77 and popliteal angle 123.21° (±12.45. There was a significant difference in the popliteal angle (p = 0.003 and SLR (0.001 when compared with the degree of dysfunction. Women showed significant differences in all tests; however, the post hoc test showed a significant difference only in the SRT (p = 0.013, and women with minimal dysfunction had greater flexibility in relation to those with severe dysfunction. Conclusion: Self-reported LBP was severe and women with higher levels of dysfunction exhibited less posterior chain flexibility.

    A 1-year prospective study was carried out to look for risk factors of farm-related injuries in Egusquiza, Santa Fe (Argentina). Information on demographic characteristics and occupational accidents was collected on (N=110, n=78) farm workers by means of personal interviews using a structured questionnaire. Monthly telephone contact was then maintained with the workers for 1 year to document all farm-related injuries. Data analysis included incidence rate, χ2 and logistic regression. Sixty-nine farm-related injuries were reported during the study period, six injuries being the maximum number affecting one worker. A total of 46.3% of the workers suffered at least one injury during the year. The incidence rate was 7.5 injuries/100 individual-month at risk. Medical assistance was needed in 26.8% of the cases and 5.8% of the injuries caused at least 1 day off work. Hospitalization for at least 1 day was required for 2.9% of the injured workers. Previous work-related injury in the family (p=0.005) (odds ratio (OR)=4.6, 95% confidence interval (CI)=1.6-13.3) and worker's activity (p=0.021) (OR=3.7, 95%CI=1.2-11.6) were associated with the dependent variable work injury. Agricultural and livestock farming are of great importance for the national economy. Workers' training on farm safety may play a key role to prevent work-related injuries and diseases.

    We examined the association between pesticide exposure and cognitive development among rural Costa Rican children in a cross-sectional study. Study participants aged 4-10 years included 17 children whose parents worked in La Amistad organic coffee plantation and 18 Las Mellizas children whose parents worked in their own small conventional coffee farms. Two spot-urine samples were collected from each participant and analyzed for organophosphorus and pyrethroids pesticide metabolites. We administered the computerized Behavioral Assessment and Research System (BARS), a figure-drawing task, and a long-term memory test to evaluate study participant's cognitive development. Although urinary pesticide metabolite levels did not vary considerably between these two groups of children, we found that Las Mellizas children performed better in BARS and the figure drawing tests than did La Amistad. The results from the linear mixed-effects models suggested that family socioeconomic status (SES) might be a significant contributor to the variation of the outcomes of the neurobehavioral tests. The effect of pesticide exposure, however, as measured in a snapshot fashion, did not play a significant role to the performance of the cognitive development evaluation. Regardless of the study limitations, needed effort should be devoted to the improvement of the SES on the La Amistad families so that their children's cognitive development would not be compromised further. Additionally, future studies should focus on addressing the limitations imposed on the snapshot assessment of pesticide exposure and on conducting cognitive development evaluation so the link between childhood pesticide exposure and their cognitive development can be thoroughly investigated.

    Antibiotics alter the homeostasis of microbial communities and select for antibiotic-resistant bacteria in the wild. Thus, the accumulation of unnaturally high concentration of these substances in the environment due to their use in human activities can be regarded as a neglected form of pollution, especially in countries with agricultural-based economies. Qualitative and quantitative information on antibiotic usage in Costa Rica is scarce, hence the design and enforcement of prevention strategies and corrective measures is difficult. To address this issue, and aiming in the long run to contribute with a more rational use of pharmaceuticals in the tropics, we characterized the hazard associated with the antibiotics used during 2008 in agriculture, aquaculture, pig farming, veterinary medicine and human medicine in the major irrigation district of Costa Rica. Hazard indicators were calculated based on antibiotic use and a weighted algorithm that also considered antibiotic fate, toxicity, and resistance. Moreover, hazard quotients were computed using maximum environmental concentrations reported for Costa Rican surface waters and predicted no effect concentrations for aquatic organisms. The number of antibiotics used in the ATID during the study were n = 38 from 15 families. Antibiotic consumption was estimated at 1169-109908 g ha(-1) year(-1) and, distinctively, almost half of this figure was traced back to phenicols. Tetracyclines, with a particular contribution of oxytetracycline, were the most widely used antibiotics in agriculture and veterinary medicine. Oxytetracycline, florfenicol, chlortetracycline, sulfamethoxazole, erythromycin, ciprofloxacin, enrofloxacin, sulfamethazine, trimethoprim and tylosin, in that order showed the highest hazard indicators. Moreover, hazard quotients greater than 1 were calculated for oxacillin, doxycycline, oxytetracycline, sulfamethazine, and ciprofloxacin.

    Full Text Available In this article we draw on the life histories of farm workers living in the Eastern Cape Province, South Africa. Subjectively interpreting their realities, the farm labourers narrated their experiences of living in the era before, during and after apartheid. The impacts of apartheid, carrying identification papers, for example, were experienced as peripheral with the most significant changes being the disruptions in their personal lives, such as a new farm owner who came to embody repression, authority, exploitation, but also paternalism and benevolence. The farm represented the space and place where complex interactions and unequal relationships between the worker and the farmer played out. The workers' narratives revealed deep-rooted connections to the land on which they lived, a land which did not belong to them. Land was for our research participants particularly important for animal husbandry, as a source of food and as a spiritual space of power where links and relationships to their ancestors were maintained and cultural practices took place. Subjugated knowledge, no formal education and farmers' paternalistic practices contributed to farm labourers' dependence on agrarian work and life on the farm.

    Workplace stress likely plays a role in health disparities; however, applying standard measures to studies of immigrants requires thoughtful consideration. The goal of this study was to determine the appropriateness of two measures of occupational stressors (‘decision latitude’ and ‘job demands’) for use with mostly immigrant Latino farm workers. Cross-sectional data from a pilot module containing a four-item measure of decision latitude and a two-item measure of job demands were obtained from a subsample (N = 409) of farm workers participating in the National Agricultural Workers Survey. Responses to items for both constructs were clustered toward the low end of the structured response-set. Percentages of responses of ‘very often’ and ‘always’ for each of the items were examined by educational attainment, birth country, dominant language spoken, task, and crop. Cronbach’s α, when stratified by subgroups of workers, for the decision latitude items were (0.65–0.90), but were less robust for the job demands items (0.25–0.72). The four-item decision latitude scale can be applied to occupational stress research with immigrant farm workers, and potentially other immigrant Latino worker groups. The short job demands scale requires further investigation and evaluation before suggesting widespread use. PMID:25138138

    Pesticides are frequently used substances worldwide, even when the use of some of them is forbidden due to the recognized adverse effect they have on the health of not only the people who apply the pesticides, but also of those that consume the contaminated products. The objectives of this study were to know the health issues of farm workers chronically exposed to pesticides, to evaluate possible damage at genetic level, as well as to explore some hepatic, renal, and hematological alterations. A transversal comparative study was performed between 2 groups, one composed of 25 farm workers engaged in pesticide spraying, and a control group of 21 workers not exposed to pesticides; both groups belonged to the Nextipac community in Jalisco, Mexico. Each member of both groups underwent a full medical history. Blood samples were taken from all farm workers in order to obtain a complete blood count and chemistry, clinical chemistry, lipid profile, liver and kidney function tests, erythrocyte cholinesterase quantification, lipid peroxidation profile, and free DNA fragment quantification. For the information analysis, central tendency and dispersion measurements were registered. In order to know the differences between groups, a cluster multivariate method was used, as well as prevalence reasons. The most used pesticides were mainly organophosphates, triazines and organochlorine compounds. The exposed group showed acute poisoning (20% of the cases) and diverse alterations of the digestive, neurological, respiratory, circulatory, dermatological, renal, and reproductive system probably associated to pesticide exposure. More importantly, they presented free DNA fragments in plasma (90.8 vs 49.05 ng/mL) as well as a higher level of lipid peroxidation (41.85 vs. 31.91 nmol/mL) in comparison with those data from unexposed farm workers. These results suggest that there exist health hazards for those farm workers exposed to pesticides, at organic and cellular levels.

    Little attention has been given to the vulnerable populations of migrant women agricultural workers. A systemic review in PubMed was carried out (1990-2008) using terms related to migrant agricultural workers, with specific focus on women. Case studies from Lebanon and California are presented to highlight key physical, psychosocial, and cultural risk factors among these working populations. The review revealed a host of potential problems that span from pesticide exposure and musculoskeletal disorders to socio-cultural barriers. Comprehensive exposure-outcome and intervention studies focusing specifically on migrant women in agriculture are lacking. In depth studies focusing on the work environment of migrant women workers in the agricultural sector are needed. Personal and environmental factors that influence health should be considered in any effective intervention aiming to influence policy making and have a positive impact on these vulnerable working populations.

    This study investigated the prevalence of self-reported musculoskeletal discomfort (MSD) and work-related factors associated with elevated MSD among Latino thoroughbred farm workers. Participants (N = 225) were recruited using a community-based purposive sampling approach to participate in in-person interviews. Of these workers, 85% experienced MSD. MSD was divided into tertiles; the upper tertile was defined as elevated. Multivariable Poisson regression revealed associations between any elevated MSD and longer tenure on horse farms, longer work hours, and poor safety climate. Elevated neck/back MSD was associated with longer tenure, longer work hours, and poor safety climate. Elevated upper extremity MSD was associated with age and poor safety climate. Elevated lower extremity MSD was associated with longer tenure, longer work hours, and being female. Musculoskeletal discomfort is common among these workers. Improving safety climate and minimizing long work hours is recommended.

    Today's dairies are growing rapidly, with increasing dependence on Latino immigrant workers. This requires new educational strategies for improving milk quality and introduction to state-of-the-art dairy farming practices. It also creates knowledge gaps pertaining to the health of animals and workers, mainly due to the lack of time and language barriers. Owners, managers, and herdsmen assign training duties to more experienced employees, which may not promote "best practices" and may perpetuate bad habits. A comprehensive and periodic training program administered by qualified personnel is currently needed and will enhance the sustainability of the dairy industry. Strategic management and employee satisfaction will be achieved through proper training in the employee's language, typically Spanish. The training needs to address not only current industry standards but also social and cultural differences. An innovative training course was developed following the same structure used by the engineering and construction industries, giving farm workers basic understanding of animal care and handling, cow comfort, and personal safety. The "Dairy Tool Box Talks" program was conducted over a 10-week period with nine sessions according to farm's various employee work shifts. Bulk milk bacterial counts and somatic cell counts were used to evaluate milk quality on the three dairy farms participating in the program. "Dairy Tool Box Talks" resulted in a general sense of employee satisfaction, significant learning outcomes, and enthusiasm about the topics covered. We conclude this article by highlighting the importance of educational programs aimed at improving overall cross-cultural training.

    Full Text Available Much uncertainty remains about the origin and public health implications of livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA. This study aimed to investigate the occurrence and prevalence of MRSA in general and LA-MRSA in particular in pigs and farm workers in five states. We collected nasal swabs from pigs and farm workers at 45 swine herds (21 antibiotic-free herds; 24 conventional herds in Illinois, Iowa, Minnesota, North Carolina and Ohio. MRSA was isolated from 50 of 1085 pigs (4.6% and 31 of 148 (20.9% of farm workers. MRSA-positive pigs and people were clustered in four conventional swine farms in Iowa and Illinois. Based on genotyping, spa type t034, a common livestock associated variant, was predominant among both human and swine isolates. These results confirm the presence of LA-MRSA in pigs and swine farm workers in the USA, but the prevalence found is relatively low compared with European studies.

    Full Text Available This study was conducted to determine the concentration and frequency distribution of certain airborne micro-organisms on cattle farms and their potential health hazards to farm workers. The samples (60 air samples and 240 hand and nasal swabs from cattle farm workers were collected from ten cattle farms (five dairy barns and five beef sheds located in the Sharkia Governorate of Egypt. Air samples were collected for microbiological examination in liquid media using an all-glass impinger whereas those for fungal examination were placed on agar plates using slit air samplers (aeroscopes. The results showed that the overall means of total culturable bacterial and fungal counts were lower in the air of dairy cattle barns than in beef cattle sheds. Identification of the isolated bacteria revealed the recovery of the following species (from dairy cattle barns versus beef cattle sheds: Staphylococcus epidermidis (26.7% vs 36.7%, S. saprophyticus (20% vs 33.3%, S. aureus (10% vs 16.7%, Enterococcus faecalis (23.3% vs 26.7%, Enterobacter agglomerans (23.3 vs 13.3%, Escherichia coli, (16.7% vs 26.7%, Klebsiella oxytoca, (10% vs 16.7%, K. pneumoniae (3.3% vs 0%, Proteus rettegri (6.7% vs 13.3%, P. mirabilis (10% vs 10%, P. vulgaris (3.3% vs 6.7%, Pseudomonas species (6.7% vs 16.7%, respectively.

    In this study, we examined the effects of pesticides in migrant farm workers from Cambodia after workplace exposure on fruit plantations in eastern Thailand. We studied 891 migrant farm workers employed on pineapple, durian, and rambutan plantations in Thailand. Data were collected via a detailed questionnaire survey and measurements of serum cholinesterase level (SChE). The majority of subjects was male (57.7%), with an average age of 30.3 years. Most subjects (76.8%) were moderately aware of good industrial hygiene practices. SChE level was divided into four groups based on the results. Only 4.4% had normal levels of cholinesterase activity, 20.5% had slightly reduced levels, 58.5% had markedly reduced levels and were "at risk," and 16.6% who had highest levels of cholinesterase inhibition were deemed to be in an "unsafe" range. SChE was classified into two groups, SChE value of 87.5 was "normal" and 39 acres, use a backpack sprayer, or have a low level of compliance with accepted industrial hygiene practices. These three classes of workers are at increased risk of chemical exposures and developing acute or chronic illness from pesticide exposures.

    More than 11 million Thai people (38%) work in agriculture, but since most are in the informal sector, government enforcement and support are very limited. As a result, working conditions on Thai farms vary greatly, putting the health of many agricultural workers at risk. A cross-sectional study in three Thai provinces collected information on the work activities and conditions of 424 farmers representing five farm types: rice, vegetable, flower, rice/vegetable, and flower/vegetable. The agricultural workers were mainly women (60%); their average age was 53 but ranged from 18 to 87 years. More than 64% worked more than 5 days/week. Seventy-four percent of them had only primary school education. A number of the health and hazardous working conditions surveyed were significantly different by farm type. Rice farmers were found to have the highest prevalence of allergies, nasal congestion, wheezing, and acute symptoms after pesticide use, while flower farmers had the lowest prevalence of these health outcomes. Rice farmers reported the highest prevalence of hazardous working conditions including high noise levels, working on slippery surfaces, sitting or standing on a vibrating machine, spills of chemicals/pesticides, and sharp injuries. The lowest prevalence of these working conditions (except noise) was reported by flower farmers. Vegetable farmers reported the highest prevalence knee problems, while rice farmers had the lowest prevalence. Among these farmers, more than 27 different types of pesticides were reported in use during the past year, with the majority reporting use once a month. The flower/vegetable farming group reported the highest frequency of good exposure prevention practices during pesticide use. They were the most likely to report using cotton or rubber gloves or a disposable paper masks during insecticide spraying. Those farmers who only grew vegetables had the lowest frequency of good exposure prevention practices, including use of personal

  1. South African farm workers' interpretation of risk assessment data expressed as pictograms on pesticide labels

    Pesticide companies and regulators in developing countries use the United Nations Food and Agricultural Organization (FAO) recommended pictograms on pesticide labels to communicate risk information based on toxicological and environmental risk assessment data. The pesticide label not only is often the only access people have to pesticide risk information, but also in many countries is a legally binding document. As a result of the crucial role pesticide labels play in protecting health and the environment and as a legal instrument, pictograms are used to overcome literacy challenges in transmitting pesticide risk information. Yet, this risk communication tool is often prone to misinterpretations of the risk information which results in hazardous exposures to pesticides for farm workers and end-users generally. In this paper, results are presented from a study with 115 farm workers on commercial vineyards in the Western Cape, South Africa, assessing their interpretations of 10 commonly used pictograms. A standardized questionnaire based on four commonly used pesticide labels was administered. Overall, 50% or more of the study farm workers had misleading, incorrect and critically confused interpretations of the label pictograms. Interpretations often reflected farm workers' social and cultural frames of reference rather than the technically intended risk information. For example, the pictogram indicating a pesticide's toxicity requires boots must be worn, evoked interpretations of 'dangerous to pedestrians' and 'don't walk through pesticides'. Furthermore, there was a gender variation in pictogram comprehension whereby males generally had more correct interpretations than females. This is a result both of a lack of training for women who are assumed to not work with pesticides, as well as a lack of pictograms relevant for female exposures. These findings challenge the viability of the United Nations current initiative to globally harmonize pictograms used on all

    Full Text Available In recent years, extended-spectrum β-lactamases (ESBL producing bacteria have been found in livestock, mainly as asymptomatic colonizers. The zoonotic risk for people working in close contact to animal husbandry has still not been completely assessed. Therefore, we investigated the prevalence of ESBL-producing Escherichia spp. in livestock animals and workers to determine the potential risk for an animal-human cross-transmission.In Mecklenburg-Western Pomerania, northeast Germany, inguinal swabs of 73 individuals with livestock contact from 23 different farms were tested for ESBL-producing Escherichia spp. Two pooled fecal samples per farm of animal origin from 34 different farms (17 pig farms, 11 cattle farms, 6 poultry farms as well as cloacal swabs of 10 randomly selected broilers or turkeys were taken at each poultry farm. For identification, selective chromogenic agar was used after an enrichment step. Phenotypically ESBL-producing isolates (n = 99 were tested for CTX-M, OXA, SHV and TEM using PCR, and isolates were further characterized using multilocus sequence typing (MLST. In total, 61 diverse isolates from different sources and/or different MLST/PCR results were acquired. Five farm workers (three from cattle farms and two from pig farms harbored ESBL-producing E. coli. All human isolates harbored the CTX-M β-lactamase; TEM and OXA β-lactamases were additionally detected in two, resp. one, isolates. ESBL-producing Escherichia spp. were found in fecal samples at pig (15/17, cattle (6/11 and poultry farms (3/6. In total, 70.6% (24/36 of the tested farms were ESBL positive. Furthermore, 9 out of 60 cloacal swabs turned out to be ESBL positive. All isolated ESBL-producing bacteria from animal sources were E. coli, except for one E. hermanii isolate. CTX-M was the most prevalent β-lactamase at cattle and pig farms, while SHV predominated in poultry. One human isolate shared an identical MLST sequence type (ST 3891 and CTX-M allele to the

    To perform classic and molecular epidemiological surveillance of human tuberculosis caused by Mycobacterium bovis in bovine supply chains at farms with PPD positive bovines in the departments of Antioquia, Boyacá and Cundinamarca during a one-year period. Livestock farms with PPD positive bovines or buffalos were visited in the study departments according to information obtained in the "Programa Nacional de Tuberculosis bovina" (National program on bovine Tuberculosis) released by ICA (Colombian Agriculture and Livestock Institute). Data on socio-demographic information and tuberculosis risk factors associated to the occupation were collected through a survey applied to all workers at the visited farms. Sputum samples were obtained after informed consent. The sputa underwent microbiological and molecular testing to identify members of the M. tuberculosis complex. Thirty-three livestock farms were visited and information of 164 workers from the bovine supply chain was collected. Staying in a PPD positive farm for more than a year, ignorance about the disease and the presence of possible vectors, like dogs and cats, were identified as possible risk factors for developing tuberculosis. No cases of tuberculosis caused by M. bovis or M. tuberculosis in workers of the visited farms were found. No cases of the disease caused by this zoonotic agent were documented in the departments of Antioquia, Boyacá and Cundinamarca.

    Full Text Available The objective of the study was to describe self-reported health symptoms, the use of personal protective gear and clothing and poor safety procedures when applying pesticides among farm workers. A total of 128 adult farm workers were interviewed using a structured questionnaire during the farming season. The commonly used pesticides included profenofos, mancozeb, chlorpyrifos, cypermethrin, deltamethrin, permethrin, lambda-cyhalothrin, endosulfan and carbosulfan. The majority (>90% of farm workers used no personal protective clothing while handling pesticides. More than one-third of farm workers ate and drank without washing their hands following pesticide handling, while a smaller number smoked or chewed gum. Wearing special boots during pesticide application was found to reduce the risk of skin rash (OR = 0.2, 95% CI: 0.06–0.66, whereas smoking when applying pesticides increased the risk of chest pain occurrence (OR = 4.0, 95% CI: 1.14–15.43, as well as forgetfulness (OR = 4.0, 95% CI: 1.30–14.02. Chewing gum and eating when applying pesticides was associated with diarrhoea (OR = 11.0, 95% CI: 1.80–6.84 and OR = 7.0, 95% CI: 1.27–3.67 respectively. The increased self-reported prevalence of post-exposure adverse health effects among farm workers was associated with poor use of personal protective clothing and poor safety practices during pesticide use and handling. These data indicate the need for improved availability and use of protective equipment, and training in crop and pest management practices to prevent risky behavioursand for safer and sustainable vegetable production.

    Migration has been associated with a higher risk of STI/HIV but few studies have assessed the sexual risk behaviour of migrant farm workers in Nigeria. An exploratory survey was conducted to assess the knowledge of HIV/AIDS and sexual risk behaviours of migrant farmers in Saki West Local Government Area, Oyo State, Nigeria. Questionnaires were used to obtain information on socio-demographic and occupational characteristics, knowledge of HIV/AIDS, sexual behaviours and history of STI symptoms. Overall 518 respondents were interviewed, slightly over half were aware of HIV/AIDS; awareness was significantly lower among the females, those aged 15-24 years and those with no formal education. Majority (80.7%) were sexually experienced, the mean age at sexual debut was 19.4 +/- 5.2 years and 18.4 +/- 4.2 years for males and females respectively. Sexual intercourse with multiple sexual partners in the past year was reported by 24.6% (males, 35.7%, versus females, 10.4%, p casual partner was reported by 9.1% (12.8% males versus 4.4% females). Only 18.2% used a condom during the last casual sexual contact. Level of awareness of HIV is unacceptably low and sexual risk behaviours are prevalent among these workers. Appropriate sexual health and HIV prevention interventions should be instituted.

    Agricultural work is hazardous, and immigrant workers perform the majority of production tasks, yet there are few data describing agricultural work and use of protective measures by demographic characteristics. We examined cross-sectionally the influence of region of birth (Mexico vs. Central America) and sex on agricultural work and use of protective measures in the MICASA cohort of immigrant Latino farm workers in Mendota, California. Of 445 participants, 293 (65.8%) were born in Mexico (163 men, 130 women) and 152 (34.2%) were born in Central America (80 men, 72 women). Men worked on average 74.4 more days than women (95% CI 62.0, 86.9) and were more likely to perform tasks requiring high levels of training or strength, such as machine operation, pruning, picking, planting, and irrigation; more likely to work in dusty conditions; and more likely to work directly with pesticides. Women predominated in packing. Respondents from Mexico were more likely to work with tomatoes and less likely to work with melon and lettuce. Central America-born respondents were less likely to engage in planting, irrigation, and pesticide use. Use of task-appropriate personal protective measures on at least a half-time basis was rare, with the exception of persons working with pesticides (a group limited to men) and for facial scarves among Central American women. Further work should focus on identifying barriers to use of preventive measures and programs to further their use. Educational models accounting for cultural factors and driving social norm change, employer engagement, and use of community health workers (promotores) may be helpful in promoting use of preventive measures.

    The province of Ontario hosts nearly a half of Canada's temporary foreign migrant farm workers (MFWs). Despite the essential role played by MFWs in the economic prosperity of the region, a growing body of research suggests that the workers' occupational safety and health are substandard, and often neglected by employers. This study thus explores farm owners' perceptions about MFWs occupational safety and general health, and their attitudes towards health promotion for their employees. Using modified grounded theory approach, we collected data through in-depth individual interviews with farm owners employing MFWs in southern Ontario, Canada. Data were analyzed following three steps (open, axial, and selective coding) to identify thematic patterns and relationships. Nine employers or their representatives were interviewed. Four major overarching categories were identified: employers' dependence on MFWs; their fragmented view of occupational safety and health; their blurring of the boundaries between the work and personal lives of the MFWs on their farms; and their reluctance to implement health promotion programs. The interaction of these categories suggests the complex social processes through which employers come to hold these paradoxical attitudes towards workers' safety and health. There is a fundamental contradiction between what employers considered public versus personal. Despite employers' preference to separate MFWs' workplace safety from personal health issues, due to the fact that workers live within their employers' property, workers' private life becomes public making their personal health a business-related concern. Farmers' conflicting views, combined with a lack of support from governing bodies, hold back timely implementation of health promotion activities in the workplace. In order to address the needs of MFWs in a more integrated manner, an ecological view of health, which includes the social and psychological determinants of health, by employers

    Indoor pesticide exposure is a growing concern, particularly from pyrethroids, a commonly used class of pesticides. Pyrethroid concentrations may be especially high in homes of immigrant farm worker families who often live in close proximity to agricultural fields, and are faced with poor housing conditions, causing higher pest infestation and more pesticide use. We investigate exposure of farm worker families to pyrethroids in a study of mothers and children living in Mendota, CA within the population-based Mexican Immigration to California: Agricultural Safety and Acculturation (MICASA) Study. We present pyrethroid exposure based on an ELISA analysis of urinary metabolite 3-phenoxybenzoic acid (3PBA) levels among 105 women and 103 children. The median urinary 3PBA levels (children=2.56 ug/g creatinine, mothers=1.46 ug/g creatinine) were higher than those reported in population based studies for the United States general population, but similar to or lower than studies with known high levels of pyrethroid exposure. A positive association was evident between poor housing conditions and the urinary metabolite levels, showing that poor housing conditions are a contributing factor to the higher levels of 3PBA seen in the urine of these farm worker families. Further research is warranted to fully investigate sources of exposure. - Highlights: • We investigate exposure of farm worker families to pyrethroids. • We present pyrethroid exposure based on an ELISA analysis of urinary 3PBA levels. • 3PBA levels were higher than those reported for the U.S. general population. • Poor housing conditions may be associated with pyrethroid exposure.

    While childhood agricultural injury has long been recognized as an important public health issue, most research has focused on family farms and there have not been many interventions targeting hired youth. This study evaluated the impact of a high school English as a Second Language (ESL) curriculum, designed to provide teen agricultural workers with the knowledge and tools to protect their health and safety in the fields. Using a quasi-experimental design, the research consisted of two intervention groups and a comparison group, and included over 2,000 students from communities that lead California in agricultural production. The research findings revealed that the curriculum had significant impact in terms of increases in knowledge and attitudes, and nearly half of those interviewed after a summer of working in the fields reported implementing new behaviors to protect their health and safety. The curriculum also had extended effects in the broader community, as the majority of students reported sharing the new information with others. The study found that a school-based ESL curriculum is an effective intervention to reach and educate teen farm workers and that ESL classes can serve as a much-needed access point for young farm workers.

    Anthropometric data are a prerequisite for designing agricultural tools and equipment that enable workers to achieve better performance and productivity while providing better safety and comfort. A set of thirty anthropometric dimensions was collected from a total sample of 371 male and female farm-workers from three different regions (west, central and east) of Java Island, Indonesia. The mean stature is 162.0 cm and 152.5 cm, the sitting height is 82.9 cm and 77.4 cm, and the body weight is 57.1 kg and 52.3 kg for male and female subjects, respectively. The index of relative sitting height (RSH) was 0.51 on average for both male and female subjects. Significant differences are found in most of the anthropometric dimensions between gender and regional data groups as well. Compared with groups of people from several other countries, the anthropometric dimensions of Indonesian people are quite similar to Indian people, but are relatively smaller than Filipino, Chinese, Japanese, British, and American people. An attempt was conducted to illustrate the use of this anthropometric database and ergonomic considerations in refining the design of traditional tools and equipment commonly in use for rice farming operations.

    In South Africa, households living in informal urban settlements, in rural areas, and on commercial farms experience various levels of dietary variety, food intake, and household hunger. Low incomes, poor food production and availability, and low spending power characterize these households. Households employ various food-coping strategies to alleviate food stress or poor food availability. To apply an existing food-coping strategy (FCS) index to assess household hunger and its usefulness in identifying the level of food stress and the patterns of food coping in farm-worker households. A cross-sectional survey was conducted. Data were gathered from women (18 to 57 years of age) responsible for food provision in a small farm-worker community in Fouriesburg, South Africa. A structured food-coping questionnaire and a standardized FCS index were used to gather data. The two most common FCS used were relying on cheaper food (chicken feet, diluted soya-mince soup) or less preferred food (meat bones) and employing food-seeking strategies (gathering wild foods), followed by consumption of seed stock (maize) and reduced portion sizes (protein foods and side dishes), resulting in starch-based diets of poor variety. Seasonal strategies varied according to the level of food stress experienced. Patterns of food coping were identified. Negative FCS (limiting food choices, only consuming starchy staples) may cause poor health status. The FCS index was effectively used to assess farm-worker household food-coping behavior (early, clear signals of the level of food distress). These results could be used to allocate appropriate food aid (type of food) and to design nutrition education programs focused on positive FCS (food gathering or bartering) in a particular community to prevent suboptimal nutritional status.

    Proper cattle-handling techniques (stockmanship) are important to ensure calm animals and a safe work environment for dairy workers on farm. The objectives of this study were to (1) assess Minnesota dairy herd owners' attitudes toward stockmanship, its perceived importance for cow comfort and worker health, and the establishment of calm cattle movement; and (2) identify current resources and methods of stockmanship training on Minnesota dairy farms. A stratified-random sample of Minnesota dairy farmers were contacted via mail to participate in a 28-question survey. One hundred eight bovine dairy producers participated. Most commonly, respondents learned their cattle handling skills from family members (42.6%) and 29.9% of producers had participated in previous stockmanship training. Producers thought that the skill of the human handler was the most important factor in establishing good cattle flow. Cattle-handling techniques was the third most common topic for new-employee orientation after training in milking parlor protocols and milking parlor disinfection. Time limitations and language barrier were considered serious challenges for worker training. Work-related injuries were responsible for lost work days in the previous year in 13.3% of dairy herds and 73.3% of those injuries occurred while working with cattle. Producers perceived that cattle-related injuries were predominantly the handler's fault: either because of not paying enough attention to the animal or due to poor cattle handling skills. Facility design was considered the least important for the occurrence of worker injuries. Although no causal inference can be made, herds that had workers who had previously participated in stockmanship training had a 810 ± 378 kg (mean ± standard error of the mean) higher rolling herd average than those that did not, even after adjusting for herd size and bulk tank somatic cell count. However, 50% of respondents were not interested in attending future stockmanship

There is a lack of analytic studies which provide detailed occupational exposure information to inform intervention development. Methods A feasibility study simulating a six month prospective cohort study was designed and undertaken. The levels of farm and worker participation and retention were analysed to determine the feasibility of the methods for wider deployment. Results Recruitment levels were comparable with other studies, with 24% of farms and 36% of non-owner workers participating. Once recruited, retention was high at 85% and 86% respectively. Conclusions The main challenges identified were in the recruitment process. Once recruited, farms and workers tended to complete the study, indicating that prospective studies in this the agricultural workforce may be feasible. Issues encountered and potential solutions for future studies are discussed.

    Noise from wind turbines is one of the most important factors affecting the health, welfare, and human sleep. This research was carried out to study the effect of wind turbine noise on workers' sleep disorder. For this, Manjil Wind Farm, because of the greater number of staff and turbines than other wind farms in Iran, was chosen as case study. A total number of 53 participants took part in this survey. They were classified into three groups of mechanics, security, and official. In this study, daytime sleepiness data of workers were gathered using Epworth Sleepiness Scales (ESS) was used to determine the level of daytime sleepiness among the workers. The 8-h equivalent sound level (LAeq,8h) was measured to determine the individuals' exposure at each occupational group. Finally, the effect of sound, age, and workers' experience on individuals' sleep disorder was analyzed through multiple regression analysis in the R software. The results showed that there was a positive and significant relationship between age, workers' experience, equivalent sound level, and the level of sleep disorder. When age is constant, sleep disorder will increase by 26% as per each 1 dB increase in equivalent sound level. In situations where equivalent sound level is constant, an increase of 17% in sleep disorder is occurred as per each year of work experience. Because of the difference in sound exposure in different occupational groups. The effect of noise in repairing group was about 6.5 times of official group and also 3.4 times of the security group. Sleep disorder effect caused by wind turbine noise in the security group is almost two times more than the official group. Unlike most studies on wind turbine noise that address the sleep disorder among inhabitants nearby wind farms, this study, for the first time in the world, examines the impact of wind turbine noise on sleep disorder of workers who are more closer to wind turbines and exposed to higher levels of noise.

    Full Text Available BACKGROUND: Human tuberculosis caused by M. bovis is a zoonosis presently considered sporadic in developed countries, but remains a poorly studied problem in low and middle resource countries. The disease in humans is mainly attributed to unpasteurized dairy products consumption. However, transmission due to exposure of humans to infected animals has been also recognized. The prevalence of tuberculosis infection and associated risk factors have been insufficiently characterized among dairy farm workers (DFW exposed in settings with poor control of bovine tuberculosis. METHODOLOGY/PRINCIPAL FINDINGS: Tuberculin skin test (TST and Interferon-gamma release assay (IGRA were administered to 311 dairy farm and abattoir workers and their household contacts linked to a dairy production and livestock facility in Mexico. Sputa of individuals with respiratory symptoms and samples from routine cattle necropsies were cultured for M. bovis and resulting spoligotypes were compared. The overall prevalence of latent tuberculosis infection (LTBI was 76.2% (95% CI, 71.4-80.9% by TST and 58.5% (95% CI, 53.0-64.0% by IGRA. Occupational exposure was associated to TST (OR 2.72; 95% CI, 1.31-5.64 and IGRA (OR 2.38; 95% CI, 1.31-4.30 adjusting for relevant variables. Two subjects were diagnosed with pulmonary tuberculosis, both caused by M. bovis. In one case, the spoligotype was identical to a strain isolated from bovines. CONCLUSIONS: We documented a high prevalence of latent and pulmonary TB among workers exposed to cattle infected with M. bovis, and increased risk among those occupationally exposed in non-ventilated spaces. Interspecies transmission is frequent and represents an occupational hazard in this setting.

    The aim of this pilot study was to evaluate respiratory behavior and respiratory indices of poultry workers on family-owned, poultry farms with 10 or less employees in North Carolina. A field study was conducted to collect data on participants (N = 24) using spirometry, fractional exhaled nitric oxide (Feno), and an interviewer-administered questionnaire. The majority of workers (76%) ranked respiratory protection as being important, yet 48% reported never or rarely wearing respiratory protection when working in dusty conditions. A large percent of workers reported eye (55%) and nasal (50%) irritation and dry cough (50%). On average, pulmonary lung function and Feno tests were normal among nonsmokers. In bivariate analysis, significant associations were identified between working 7 days on the farm (P = .01), with eye irritation, and working 5 or fewer years in poultry farming (P = .01). Poultry workers on family-owned farms spend a considerable amount of work time in poultry houses and report acute respiratory-related health symptoms. Administrative controls among small, family-owned poultry farms are necessary to improve and promote safety and health to its employees.

Materials and Methods: Fecal swabs from different poultry species (n=150 and poultry farm workers (n=15 were analyzed for E. coli and screened for virulence genes (stx1, stx2, eaeA, and hlyA by multiplex PCR. Virulent E. coli was serotyped based on their "O" antigen and then genotyped using ERIC-PCR. Results: A total of 134 E. coli isolates (122/150 from poultry and 12/15 from farm workers were recovered. Virulence genes were detected in a total of 12 isolates. Serological typing of the 12 virulent E. coli revealed nine different serotypes (O2, O49, O60, O63, O83, O101, O120, UT, and Rough. ERIC-PCR genotyping allowed discrimination of 12 virulent E. coli isolates into 11 ERIC-PCR genotypes. The numerical index of discrimination was 0.999. Conclusion: Our findings provide information about the wide genetic diversity and discrimination of virulent E. coli in apparently healthy poultry and poultry farm workers of Andhra Pradesh (India based on their genotype.

    Full Text Available [b][/b]Objective. To determine the species, prevalence, and associated risk factors of intestinal parasites in farm workers’ children in a representative sample in the southeastern Anatolian region of Turkey. Materials and method. A total of 333 farm workers’ children, under the age of six years, were selected using the probability sampling method. Mean age of the children was 3.63±0.5; 55.5% were female. Data were collected using a structured questionnaire and laboratory analysis of faecal samples. Results. The overall prevalence was 44.6% and the infected children had single, double, and triple parasitic infections at 72.3%, 23.0%, and 4.7%, respectively. The most common parasite was [i]G. intestinalis[/i] (47.97%, followed by [i]E. vermicularis[/i] (37.84%, [i]T. saginata[/i] (27.03%, [i]H. nana[/i] (12.16%, and [i]A. lumbricoides[/i] (7.43%, respectively. Age, gender, illiteracy of the households, poverty, absence of toilets, bathrooms, and kitchens at the place of residence, lack of safe potable water, geophagia (soil eating habit, and being a child of a seasonal farmworker were the most significant factors associated with intestinal parasitic infection (P<0.05. [i]G. intestinalis[/i] and [i]E. vermicularis[/i] were found as the most common parasites that cause salivation, abdominal pain, and tiredness (P<0.05. Conclusion. The study revealed that health education programmes for farm workers and farmers should be improved to increase awareness about living and working conditions, in order to control intestinal parasites. However, early diagnosis and treatment services for intestinal parasites should be provided by primary health care staff in the national child screening programme in agricultural populations.

    Previous studies have demonstrated that acute poisoning from exposure to organophosphate (OP) pesticides in agricultural workers causes adverse health effects. However, neuropsychological and cognitive effects of chronic occupational exposure to OP pesticides remain controversial. To identify, evaluate, and systematize existing evidence regarding chronic exposure to OP pesticides and neuropsychological effects in farmworkers. Using the PubMed search engine, a systematic review process was implemented and replicated according to the PRISMA statement. Eligibility criteria included workers over 18 years of age exposed to OP pesticides as well as assessment of neuropsychological and cognitive functioning. Search terms were in English and Spanish languages and included organophosphate and workers. Of the search results, 33 of 1,256 articles meet eligibility criteria. Twenty-four studies found an association between chronic occupational exposure to OP pesticides and low neuropsychological performance in workers. We classified nine of the studies to have study design limitations. Studies indicated occupational exposure to OP pesticides is linked to difficulties in executive functions, psychomotor speed, verbal, memory, attention, processing speed, visual-spatial functioning, and coordination. Nine studies find no relationship between OP pesticides exposure and neuropsychological performance. Overall, evidence suggests an association between chronic occupational exposure to OP pesticides and neuropsychological effects. However, there is no consensus about the specific cognitive skills affected.

    We report 3 patients (26, 31, and 33 years) who worked at the same fish farm for several years. They experienced symptoms of rhinoconjunctivitis and bronchial asthma while classifying fish by size. Their asthma gradually worsened to the extent that it became persistent and required daily medication with inhaled corticosteroids and bronchodilators. Symptoms improved during weekends and holidays. All 3 patients could eat turbot. Our study showed that the patients were allergic and that sensitization was probably by inhalation. The allergens were parvalbumin in 1 case and a different allergen in the remaining 2 patients.

    2012-08-01

    Although the frequency of self-medication among Mexican migrants has been well-documented in the public health literature, the multiple reasons for this practice are poorly understood. Most studies point to migrants' cultural preferences for Mexican medications, their prior experiences in countries where antibiotics are loosely regulated, and their lack of access to health care as the primary factors behind their self-medication. Based on participant observation and in-depth interviews with 23 Mexican migrants in a farm working community in the interior of California, we argue that occupational vulnerability is an equally important factor that encourages self-medication. All 23 of our interviewees reported having engaged in some degree of self-medication, notable in this location 8 h from the US-Mexico border. Among interviewees, occupational vulnerability represented an even more important factor influencing self-medication than lack of health insurance or lack of legal documentation. While interviewees did express a preference for Mexican medications as more potent and effective, this did not necessarily translate to a preference for using them without a doctor's supervision. Finally, we show that rather than remaining unaware of the risks of following this custom "transported from Latin America", Mexican migrants devised an elaborate hierarchy of resort of the safest self-medication practices to follow.

    Studies have shown that farming is associated with many agricultural workers experiencing low back pain (LBP). The rehabilitation of these workers should facilitate their functioning, activities and level of participation in an adequate way. The objectives of this study were to identify the health components associated with LBP and to evaluate the effectiveness of the interventions in returning agricultural workers with LBP to their vocation using the International Classification of Function (ICF) -based tools. Thirty-one full time agricultural workers from 3 different Indian states were prospectively assessed using the ICF core set for LBP. ICF core sets permitted analysis of limitations of function from both the participant and rehabilitation team's perspectives. Each ICF category was rated using an ICF qualifier. The components identified were linked to the ICF categorical profile and assessment sheet. The clinicians identified the global, service program and cycle goals based on ICF. The participants' functioning was followed over a 4-month period. After intervention, the participants were able to undergo their routine activities without increases in pain. However, on returning to active farming, participants noted few improvements in the components d410 (changing basic body position), d415 (maintaining body position), d430 (lifting and carrying objects), d465 (moving around using equipment), d850 (remunerative employment) and d859 (work and employment, other specified and unspecified). The results of the study conclude that the current interventions for LBP are not effective in returning agriculture workers with LBP in India to pain-free farming. There is an urgent need to individualize the health needs of agriculture workers.

    Full Text Available This study describes alcohol consumption in five Western Cape Province communities. Cross-sectional data from a community household sample (n = 591 describe the alcohol use patterns of adult males and females, and farm workers vs. others. Data reveal that men were more likely to be current drinkers than women, 75.1% vs. 65.8% (p = 0.033; farm laborers were more likely to be current drinkers than individuals in other occupations 83.1% vs. 66.8% (p = 0.004.

The legacy of “Dop” contributes to current risky drinking behaviors. Farm owners or managers were interviewed on 11 farms, they described working conditions on their farms and how the legacy of “Dop” is reflected in the current use of alcohol by their workers. “Dop” was given to farm workers in the past on six of the 11 farms, but was discontinued for different reasons. There is zero tolerance for coming to work intoxicated; farm owners encourage responsible use of alcohol and assist farm workers in getting help for alcohol problems when necessary. The farm owners report some positive initiatives, were ahead of the movement to provide meaningful wages, and provide other important amenities. Further research is needed to assess whether progressive practices on some farms will reduce harmful alcohol use.

    Agricultural pesticide use in Viet Nam has more than tripled since 1990. However, pesticide legislation and regulations have not been developed in response to this large increase in usage, as a result of which pesticides pose a serious threat to human health and the environment. This paper identifies the need to improve pesticide regulations in Viet Nam through a comparative analysis of pesticide regulations in Viet Nam and the United States of America, where the rate of acute poisoning among agricultural workers is much lower than in Viet Nam and where information pertaining to pesticide regulations is made accessible to the public. The analysis identified several measures that would help to improve Viet Nam's pesticide regulations. These include enhancing pesticide legislation, clarifying the specific roles and active involvement of both the environmental and health sectors; performing a comprehensive risk-benefit evaluation of pesticide registration and management practices; improving regulations on pesticide suspension and cancellation, transport, storage and disposal; developing import and export policies and enhancing pesticide-related occupational safety programmes.

    Full Text Available Abstract Background Wastewater use in urban agriculture is common as a result of rapid urbanisation, and increasing competition for good quality water. In order to minimize risks to farmers and consumers of wastewater irrigated produce the World Health Organization (WHO has developed guidelines for the safe use of wastewater in agriculture. These guidelines are based on a Quantitative Microbial Risk Assessment (QMRA model, though the reliability of this model has been questioned due to a lack of primary data. This study aimed to assess the ability of the WHO guidelines to protect farmers’ health, by identifying and quantifying key exposures associated with the transmission of faecal pathogens in wastewater irrigated agriculture. Methods Eighty farmers were observed and interviewed during the dry and wet seasons, and water and soil samples were analysed for the presence of E. coli. STATA 12 was used for descriptive analyses of farmers’ exposure and risk practices, and also to determine risk factors for soil and irrigation water contamination, while the WHO QMRA model and @Risk 6 were used to model farmers’ infection risk to pathogens. Results The results showed that although irrigation water was highly contaminated (5.6 Log E. coli/100 ml, exposure to farm soil (2.3 Log E. coli/g was found to be the key risk pathway due to soil-to-mouth events. During the observations 93 % of farmers worked barefoot, 86 % experienced hand-to-soil contact, while 53 % experienced ‘soil’-to-mouth events, while no ‘water’ to mouth contacts were observed. On average, farmers were found to have 10 hand-to-mouth events per day. From the indicator based QMRA model the estimated norovirus infection risk to farmers was found to be higher than guidelines set by the WHO. Conclusions This study found exposure to soil as the critical pathway of pathogen risk in wastewater farmers, and that this risk exceeded recommended health targets. The study recommends

This study aimed to investigate the effect of noise emitted from wind turbines on general health, sleep and annoyance among workers of manjil wind farm, Iran. A total number of 53 workers took part in this study. Based on the type of job, they were categorized into three groups of maintenance, security and office staff. The persons' exposure at each job-related group was measured by eight-hour equivalent sound level (LAeq, 8 h). A Noise annoyance scale, Epworth sleepiness scale and 28-item general health questionnaire was used for gathering data from workers. The data were analyzed through Multivariate Analysis of variance (MANOVA) test, Pillai's Trace test, Paired comparisons analysis and Multivariate regression test were used in the R software. The results showed that, response variables (annoyance, sleep disturbance and health) were significantly different between job groups. The results also indicated that sleep disturbance as well as noise exposure had a significant effect on general health. Noise annoyance and distance from wind turbines could significantly explain about 44.5 and 34.2 % of the variance in sleep disturbance and worker's general health, respectively. General health was significantly different in different age groups while age had no significant impact on sleep disturbance. The results were reverse for distance because it had no significant impact on health, but sleep disturbance was significantly affected. We came to this conclusion that wind turbines noise can directly impact on annoyance, sleep and health. This type of energy generation can have potential health risks for wind farm workers. However, further research is needed to confirm the results of this study.

    To examine whether exposures or activities in farming, forestry and related occupations explain the excess incidence of germ cell cancer (GCC) observed among male employees in one of the six car-manufacturing plants that is located in a geographic area where farming is frequent. A cohort based case-control study was conducted among workers in six car-manufacturing plants located in areas with different industrial structure. The study involved 188 cases of germ cell cancer identified through active retrieval in 38 hospitals and 1000 controls, drawn from administrative accounting files, individually matched by year of birth (± 2 years). Information regarding tasks and exposures and potential confounding variables were obtained by face-to-face or telephone interviews. Odds ratios (OR) and 95% confidence intervals (CI) were estimated using a conditional logistic regression model adjusted for cryptorchidism and other potential confounders. In this case-control study 5.3% of cases and 6.3% of controls ever worked in agriculture or livestock farming. No increased risks were observed for working in agriculture (OR=0.8 95% CI: 0.4-1.6), livestock farming (OR=0.8 95% CI: 0.4-1.6) or for exposure to pesticides (OR=0.7 95% CI: 0.3-1.7), for exposure to fertilizers (OR=0.8 95% CI: 0.4-1.8) and disinfectants (OR=1.0 95% CI: 0.3-2.8). There were no statistically significant increases in risk associated with ever exposure to salt based wood protection agents (OR=2.3 95% CI: 0.6-9.1), working with plywood (OR=1.4 95% CI: 0.6-3.2), coated wood (OR=1.4 95% CI: 0.5-3.9) or working in forestry (OR=1.7 95% CI: 0.5-6.4). Lagging of exposures did not alter the results. The observed excess incidence in the cohort of automotive workers can be hardly explained by previous or concurrent work in farming or forestry. Because of the small numbers of subjects ever employed in farming the statistical power in assessing associations between agricultural work and agricultural exposures was limited

    Full Text Available Immigrants are generally perceived to be information poor, meaning they face major challenges with finding and using greatly needed everyday information. However, little research exists from an information behaviour perspective as differences in language, culture, and other factors such as access make immigrants a difficult population to study. We explored the everyday information behaviour and information grounds of migrant Hispanic farm workers through field observation and interviews with users, non-users, and staff of community technology centres in a major agricultural area. Findings suggest that personal networks having various levels of credibility were used more readily than any other type of information source. Credibility and use of various sources seemed to relate to personal status as well as interest in information.

    Sexual prejudice is linked to hate crimes, mental health, risk behaviors, and stigma. Few studies have examined sexual prejudice among Latinos. We surveyed 382 college students in Puerto Rico. A structural model tested whether contact and positive experiences with homosexuals, perceived similarities with peers' attitudes toward homosexuality, and religiosity were predictive of sexual prejudice among Puerto Rican young adults. Sex differences in the structural model were explored. With the exception of peers' attitudes toward homosexuality, all study variables predict sexual prejudice. No sex differences were found. Implications for decreasing sexual prejudice among Puerto Rican youth in a college setting are discussed. PMID:18689195

    2014-05-01

    This study investigated whether rural workers who have higher workplace satisfaction are less likely to report quad bike loss of control events (LCEs). Two independent samples of farmers completed a survey regarding LCEs and workplace satisfaction. In the first sample (n = 130) analysis revealed no relationship (p = 0.74) between workplace satisfaction and LCEs but lower rates of LCEs were reported by employees (IRR 0.52, 95%CI 0.31-0.86) compared to self-employed participants. In the second sample (n = 112), workplace satisfaction was weakly related to LCEs (IRR 1.04, 95%CI 1.00, to 1.09) with participants who found their job more psychologically demanding more likely to have had an LCE (IRR 1.14, 95%CI 1.05-1.23). Exploring the role of psychological demands on safety behaviour with respect to quad bike use, may help to address this important safety issue.

    Full Text Available Desde hace dos décadas los jornaleros tamaulipecos han recibido un considerable número de visas H-2A para trabajar en la agricultura en Estados Unidos. Los empleadores estadounidenses muestran una cierta preferencia por los jornaleros tamaulipecos, ya que la cercanía de Tamaulipas a la frontera disminuye los costos de transporte, que deben ser asumidos por los empleadores. Los programas de trabajadores huéspedes para mano de obra no cualificada exponen a los trabajadores foráneos al abuso y la explotación. La falta de cumplimiento con algunas regulaciones federales como el Estándar de Protección de los Trabajadores o el Seguro de Compensación Laboral incrementa el riesgo de envenenamiento por agroquímicos y accidentes entre los jornaleros, y aquellos que sufren accidentes laborales o enfermedades no reciben atención médica. Este artículo examina los problemas de salud sufridos por los trabajadores tamaulipecos empleados con visas H-2A en la agricultura estadounidense.From two decades ago Tamaulipas' farm workers have received a large amount of H-2A visas to work in the farming sector. U.S. farmers find it appealing to hire Tamaulipas' workers because of the proximity of Tamaulipas to the frontier, which lowers transportation costs, which have to be paid by the employers. It is well reported that low-skilled guest worker programs leaves foreign workforce open to abuse and exploitation. Poor compliance with federal regulations like the Worker Protection Standard and Workers Compensation Insurance increases the risk of pesticide poisoning and injuries among agricultural workers, and those who suffer work-related injuries or illnesses forgo needed medical care. This paper examines the health problems suffered by Tamaulipas's H-2A workers employed in U.S. agriculture.

    To determine prevalence of HIV and HIV-related behaviours in female seasonal farm workers (FSFWs) in two provinces of Souss Massa Draa (SMD) region in Morocco. SMD has a higher burden of HIV compared with other parts of Morocco and is characterised by a substantial aggregation of FSFW. We carried out a cross-sectional HIV biobehavioural survey using cluster-based sampling of farms in the provinces Chtouka Aït Baha and Taroudant Ouled Teïma in 2014. HIV testing was done using the Determine HIV-1/2 rapid test and reactive specimens were tested using ELISA and western blot. Collected data were post hoc weighted for region-based stratification and adjusted for clustering effects using complex survey functions of SPSS (V.21). Among those eligible to participate, the response rate was 92.8%. HIV prevalence was 0.9% (95% CI 0.4% to 2.4%) among 520 recruited participants. A high proportion of respondents (67.7%) had no education. Ever having sex was reported by 79.8% and among these, 12.7% ever exchanged sex for money or goods. Sixty-one per cent reported condom use at most recent commercial vaginal sex in the past 12 months. STI symptom recognition was found to be low because 62.4% and 46.8% of FSFW could not report any STI symptoms in men and women, respectively. Twenty-seven per cent of respondents had an HIV test in the past 12 months. In multivariable analysis, those with primary or higher education (adjusted OR (aOR)=2.38, 95% CI 1.33 to 4.27) and those who participated in an HIV educational session at their workplace (aOR=11.00, 95% CI 3.99 to 30.31) had higher odds of ever been tested for HIV. Although we found a relatively low HIV prevalence among FSFW in SMD, HIV interventions should be intensified, in particular, in a subgroup of women who are involved in sex work.

    Full Text Available Abstract Background The Boston Puerto Rican Health Study is an ongoing longitudinal cohort study designed to examine the role of psychosocial stress on presence and development of allostatic load and health outcomes in Puerto Ricans, and potential modification by nutritional status, genetic variation, and social support. Methods Self-identified Puerto Ricans, aged 45-75 years and residing in the Boston, MA metro area, were recruited through door-to-door enumeration and community approaches. Participants completed a comprehensive set of questionnaires and tests. Blood, urine and salivary samples were extracted for biomarker and genetic analysis. Measurements are repeated at a two-year follow-up. Results A total of 1500 eligible participants completed baseline measurements, with nearly 80% two-year follow-up retention. The majority of the cohort is female (70%, and many have less than 8th grade education (48%, and fall below the poverty level (59%. Baseline prevalence of health conditions is high for this age range: considerable physical (26% and cognitive (7% impairment, obesity (57%, type 2 diabetes (40%, hypertension (69%, arthritis (50% and depressive symptomatology (60%. Conclusions The enrollment of minority groups presents unique challenges. This report highlights approaches to working with difficult to reach populations, and describes some of the health issues and needs of Puerto Rican older adults. These results may inform future studies and interventions aiming to improve the health of this and similar communities.

    Full Text Available This essay looks back at the production of Puerto Rican films in the 1980s and 1990s as the point of departure for young Puerto Rican filmmakers in the first decades of the 21st century. Even as the stories of this newer generation differ, their concern with the island image and diasporic movement continue to question Puerto Rican identity. Problems of local film production and outside distribution remain for each film project. This essay analyzes a number of key films by a diverse group of directors whose goal is to rethink the concept of a Puerto Rican cinema.

    Puerto Ricans in the US experience higher deaths from diabetes and other causes compared to non-Hispanic Whites and other Hispanic groups. We compared mortality in Puerto Rico to that of Puerto Ricans in the US as a first step to investigate if similar or worse mortality patterns originate from the sending country (Puerto Rico). Age-adjusted death rates were generated using national vital statistics databases in the US and territories for all-cause and the top ten causes of death among Hispanics in 2009. Mortality ratios in the archipelago of Puerto Rico (APR) were compared to mainland US Puerto Ricans (MPR). Rates for other ethnic/racial groups (Mexican Americans, Cubans, and non-Hispanic Whites, Blacks, American Indians, and Asians) were calculated to provide a context. APR had significantly higher all-cause mortality and death rates for diabetes, nephritis, pneumonia/influenza, and homicide/assault compared to MPR (APR/MPR ratio for all-cause: 1.08, diabetes: 2.04, nephritis: 1.84, pneumonia/influenza: 1.33, homicide/assault: 3.15). Death rates for diabetes and homicide/assault (particularly among men) were higher among APR compared to any other racial/ethnic groups in the US. In contrast, deaths from heart disease, cancer, and chronic liver disease were significantly lower for APR compared to MPR (MPR/APR ratio 0.72, 0.91, 0.41, respectively). Among APR women, death rates for these causes were also lower compared to any other group in the US. Substantial mortality variability exists between Puerto Ricans in Puerto Rico and those in the US, re-emphasizing the need to study of how socio-environmental determinants of health differ in sending and receiving countries. Explanations for disparate rates include access to and availability of healthcare and unique factors related to the migration experience of this group.

    Puerto Rican children share a disproportionate burden of prematurity and asthma in the United States. Little is known about prematurity and childhood asthma in Puerto Rican subjects. We sought to examine whether prematurity is associated with asthma in Puerto Rican children. We performed a case-control study of 678 children aged 6 to 14 years with (n = 351) and without (n = 327) asthma living in San Juan, Puerto Rico. Prematurity was defined by parental report for our primary analysis. In a secondary analysis, we only included children whose parents reported prematurity that required admission to the neonatal intensive care unit. Asthma was defined as physician-diagnosed asthma and wheeze in the prior year. We used logistic regression for analysis. All multivariate models were adjusted for age, sex, household income, atopy (≥1 positive IgE level to common allergens), maternal history of asthma, and early-life exposure to environmental tobacco smoke. In a multivariate analysis there was a significant interaction between prematurity and atopy on asthma (P = .006). In an analysis stratified by atopy, prematurity was associated with a nearly 5-fold increased odds of asthma in atopic children (adjusted odds ratio, 4.7; 95% CI, 1.5-14.3; P = .007). In contrast, there was no significant association between prematurity and asthma in nonatopic children. Similar results were obtained in our analysis of prematurity requiring admission to the neonatal intensive care unit and asthma. Our results suggest that atopy modifies the estimated effect of prematurity on asthma in Puerto Rican children. Prematurity might explain, in part, the high prevalence of atopic asthma in this ethnic group. Copyright © 2013 American Academy of Allergy, Asthma & Immunology. Published by Mosby, Inc.

    Full Text Available Objective of this work is to investigate the structural change and economic dynamics of farms pursuing diversification and differentiation strategies in Italy. The analysis was performed on a panel of data built on the basis of information collected by the Italian FADN between 2003-2009. For the purpose of the analysis, we divided the population of commercial Italian farms into a five-fold farm typology based on size and the extent of diversification and differentiation strategies adopted by the farms. In detail, farms are defined as differentiated when they make use of a system of quality certification, while they are defined as diversified when they take up non farming activities (agritourism, social farms etc.. The findings show that conventional farms remain by far the largest category within the population of Italian commercial farms, while only 13% of the total commercial farms are classified as differentiated and/or diversified. Farms adopting product differentiation strategies are found to have an income growth path similar to that of conventional farms. Yet the category of diversified farms is the only one showing an upward trend with regard to income per worker in the observed years, while farms relying entirely on agricultural products appear to perform poorly in terms of labour productivity.

    Conway, Kevin P; Swendsen, Joel D; Dierker, Lisa; Canino, Glorisa; Merikangas, Kathleen R

    2007-06-01

    Although acculturation to the United States has been associated with an increase in substance, mood, and anxiety disorders in Latino populations, few studies have examined this concept relative to comorbidity among these syndromes. This study compares the prevalence and patterns of psychiatric comorbidity among Puerto Ricans with substance use disorders living in San Juan (Puerto Rico) to those who have migrated to New Haven (Connecticut) and examines the association between acculturation-related stress and the prevalence and patterns of psychiatric comorbidity among those who have migrated to New Haven. Lifetime levels of nearly all comorbid psychiatric disorders among respondents with substance use disorders were generally similar across sites. However, the risk of any co-occurring psychiatric disorder was higher among substance use disorder cases in New Haven who reported high levels of total acculturation stress and family-specific acculturation stress. These findings were generally accounted for by associations between affective disorders and high scores on these indicators of acculturation stress. The overall prevalence and patterns of psychiatric comorbidity are remarkably similar among Puerto Rican substance abusers whether they live in San Juan or have migrated to New Haven, thereby demonstrating robustness to differences in geographic location. Nevertheless, the degree of acculturation-related family stress is positively associated with co-occurring substance and psychiatric disorders, particularly affective disorders. Intervention in family strain related to the acculturation process may diminish the development of comorbid mental disorders and assist in implementing successful treatment of substance abuse.

    To characterize the health status of older island Puerto Ricans, a segment of the U.S. population that has been largely overlooked in aging research. Data from the 2002 Puerto Rican Elderly Health Conditions Project and the 2002 Health and Retirement Study are used to examine differences in disease, disability, and self-rated health among island Puerto Ricans and the mainland U.S.-born older adult population. Differences are further examined by gender. Island Puerto Ricans were less likely to have heart disease, stroke, lung disease, cancer, activities of daily living (ADL) limitations, and poor self-rated health, but more likely to have hypertension and diabetes. Island Puerto Rican women had worse health relative to island Puerto Rican men. Recent challenges in the funding and provision of health care in Puerto Rico are worrisome given the large number of aging island adults, many of whom have hypertension and diabetes, two conditions that require long-term medical care.

    2014-11-01

    Full Text Available We assess the utility of mixed-frequency models to forecast the quarterly growth rate of Costa Rican real GDP: we estimate bridge and MiDaS models with several lag lengths using information of the IMAE and compute forecasts (horizons of 0-4 quarters which are compared between themselves, with those of ARIMA models and with those resulting from forecast combinations. Combining the most accurate forecasts is most useful when forecasting in real time, whereas MiDaS forecasts are the best-performing overall: as the forecasting horizon increases, their precisionis affected relatively little; their success rates in predicting the direction of changes in the growth rate are stable, and several forecastsremain unbiased. In particular, forecasts computed from simple MiDaS with 9 and 12 lags are unbiased at all horizons and information sets assessed, and show the highest number of significant differences in forecasting ability in comparison with all other models.

    Breast cancer survivors do not engage in appropriate levels of physical activity, despite the known benefits of such activity. This study aims to describe physical-activity levels and the barriers to it in a group of Puerto Rican breast cancer survivors, as well as detailing their preferences for an intervention. Participants who finished their chemotherapy and/or radiotherapy for breast cancer at least 4 months prior to the study were included. Demographic, anthropometric, and clinical data were obtained. The Godin Leisure-Time Exercise Questionnaire (GLTEQ) and questionnaires on exercise self-efficacy, barriers to self-efficacy, modeling, and social support were filled out by study participants. Data on access to exercise equipment and preferences regarding a physical-activity intervention were collected. Descriptive statistics and correlation analyses were performed. Fifty breast cancer survivors were recruited. Almost all the participants reported that they did not engage in any kind of strenuous physical activity (94%), with more than three fourths (76%) reporting that they did not even participate in any kind of moderate physical activity. The GLTEQ score was associated with barriers to selfefficacy, while the association with exercise self-efficacy approached significance (p = 0.055). Nearly half of the patients (44%) had access to exercise equipment. Preferred methods for the delivery of physical-activity interventions were participating in group settings (72%) and receiving material in the postal mail (44%). The study described herein reports on the low levels of physical activity being practiced by a group of Puerto Rican breast cancer survivors, despite the fact that many of them had access to exercise equipment and facilities. Further studies aimed at understanding breast cancer survivors' barriers to physical activity and at developing culturally competent interventions to increase the levels of such activity are warranted.

    Background Little is known about paternal psychosocial factors and childhood asthma. Objective To examine the link between maternal and paternal psychosocial stress and asthma outcomes in young children. Methods Parents of 339 pairs of Puerto Rican twins were interviewed individually about their own psychosocial stress and about asthma in their children at age 1 and again about their child’s asthma at age 3. Fathers were asked about symptoms of post-traumatic stress disorder (PTSD), depression, and anti-social behavior. Mothers were asked about depressive symptoms. Outcomes assessed in children included recent asthma symptoms, oral steroid use and hospitalizations for asthma in the prior year, and asthma diagnosis. Generalized estimated equation models were used for the multivariate analysis of parental psychosocial stress and asthma morbidity in childhood. Results After multivariable adjustment, paternal PTSD symptoms, depression, and anti-social behavior were each associated with increased asthma symptoms at age 1 (e.g., OR =1.08 for each 1-point increase in PTSD score, 95% CI=1.03–1.14). Maternal depressive symptoms were associated with an increased risk of asthma hospitalizations at age 1 year. At age 3 years, maternal depressive symptoms were associated with asthma diagnosis and hospitalizations for asthma (OR for each 1-point increase in symptoms=1.16, 95% CI=1.00–1.36]). In an analysis combining 1 and 3 year outcomes, paternal depression was associated with oral steroid use, maternal depressive symptoms were associated with asthma hospitalizations and asthma diagnosis, and parental depression was associated with hospitalizations for asthma. Conclusions Both paternal and maternal psychosocial factors may influence asthma morbidity in young Puerto Rican children. PMID:21194742

  3. Female employment and the social reproduction of the Puerto Rican working class.

    Science.gov (United States)

    Safa, H I

    1984-01-01

    The rapid industrialization, migration and urbanization processes in Puerto Rico since 1940 have been responsible for the increase in the rate of female employment from 22.1% in 1960 to 27.8% in 1980, while the rate of male employment has fallen. This rise in female employment is significant in an era of growing unemployment and economic crises. There is a tendency for management to prefer young, single women workers over the older, married or formerly married women. The former tend to be better educated, work harder, complain less and are likely to be burdened with household or childcare responsibilities, which can lead to fatigue or even absenteism on the job. Their strong background in patriarchal rural traditions makes it easier for them to accept the authority of thier employers without question. With a knowledge that they can find other, similar work, the younger women are not troubled by plant problems such as production cutbacks, and layoffs. Their primary concern is not job stability, but money, which is used for future plans which include marriage, children and a new home. In contrast, older women view job security as more important. Their years of being in the labor force and the sense of self worth they have acquired as a result of it, tend to make them critical of authority. The contribution of working women to the household economy in Puerto Rican working class families varies with age and marital status. Older, married and formerly married women carry a heavier financial burden, assume a larger share of household responsibilities, and are often the sole supporters of their families. Younger women usually share their responsibilities with a relatively large number of siblings. Export-led industrialization has contributed to male outmigration from Puerto Rico, but as women lose their factory jobs due the factories being relocaged elsewhere as part of Operation Bootstrap, women too may join the migration flows.

    2016-08-01

    Full Text Available In 2014, the average employment of hired workers in California crop and livestock agriculture, counting all occupations, rose by 10% to 410,900. However, although the state reports the number of jobs on farms regularly, it does not report the number of workers who fill these jobs. We analyzed all Social Security numbers reported by farm employers in 2014 and found two workers for each average or year-round equivalent farm job, making the total number of farmworkers employed in agriculture 829,300, or twice average employment. Approximately 83% of farmworkers had their maximum earnings with an agricultural employer in 2014, and almost 80% of those primary farmworkers were employed by crop support firms (392,000 or fruit and nut farms (154,000. Over 60% of all workers had only one farm employer, followed by 27% with two or more farm employers, and 35% were employed in Kern (116,000, Fresno (96,000 and Monterey (82,000 counties. These data show that California has a remarkably stable farm workforce: most farmworkers are attached to one farm employer, often a labor contractor who moves them from farm to farm.

  6. Incidence of Poverty and the Role of Non-Farm Activities

    The incidence of poverty, poverty gap and the severity of poverty for the nine agro-climatic zones of the country (rice/wheat Punjab, mixed Punjab, cotton/wheat Punjab, low intensity Punjab, Barani Punjab, cotton/wheat Sindh, rice other Sindh, Khyber Pakhtunkhwa and Balochistan) were calculated for farming and non-farming households. The indices of poverty were also measured for households that only did farming, undertook farming and non-farm activities and those that did no farming in the various agro-climatic zones. Finally, incidence and severity of poverty as well as the spread of income among the poor for non-farm wage earners, farm wage earners, non-farm self-employed and the crop cultivators in the nine agro-climatic zones of rural Pakistan was also carried out. The relationship between incidence of poverty and non-farm activities is ambivalent with non-farm households being better off in regions that are less fertile. The incidence of poverty was highest amongst farm wage workers, followed by non-farm wage workers, non-farm self-employed and lastly crop cultivators. (author)

    as part of a larger project entitled “Economic analyses of the future development of organic farming – effects at the field, farm, sector and macroeconomic level”. The project links effects at the field-level with analyses at the farm level. These effects are then used in sector and macroeconomic analyses......, which are described in other reports from Food and Resource Economic Institute (Jacobsen, 2005 and Andersen et al., 2005). This gives coherent results from the field to the macroeconomic level regarding changes in technology and legislation.......The purpose of this report is to present possible impacts of new technology and changes in legislation on the profitability of different types of organic farms. The aim is also to look at both the current and future trends in the organic area in Denmark. The farm level analyses are carried out...

    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.

    Enamel lesions in development were identified and classified in patients of Llano Grande de Cartago, examined at the Facultad de Odontologia of the Universidad de Costa Rica. A guide is provided over the topic. 15 children and 2 Costa Rican adults were selected. Clinical examinations, radiographs and clinical photographs were used as data collection method. Dental defects of the enamel were classified according to the possible genetic causes and without genetic causes. Imperfect Amelogenesis (IA) was diagnosed in 10 of patients. Hypoplastic IA was determined in 3 siblings with autosomal recessive inheritance, for 16% of the total sample. Hypomineralized IA was identified in an adult and two of his sons, with autosomal dominant inheritance. The remaining 4 cases of IA have been sporadic. Lesions of dental fluorosis were determined in the Horowitz index in 4 individuals, from 2 unrelated families. Other defects unspecified of the enamel or hypoplasias were found in 3 individuals. Enamel lesions in development should be classified with precision, for the purpose to inform to patients affected about their condition, origin, prognosis and appropriate treatment. The basis are established to implement reliability in the construction of family genealogy, identification and classification of enamel lesions, as well as the probabilities of future generations to express the lesions in the enamel of temporary or permanent dentition [es

    2009-06-01

    An emerging body of research shows that perceived discrimination adversely influences the mental health of minority populations, but is it also deleterious to physical health? If yes, can marriage buffer the effect of perceived discrimination on physical health? We address these questions with data from Puerto Rican and Mexican American residents of Chicago. Multivariate regression analyses reveal that perceived discrimination is associated with more physical health problems for both Puerto Rican and Mexican Americans. In addition, an interaction effect between marital status and perceived discrimination was observed: married Mexican Americans with higher perceived discrimination had fewer physical health problems than their unmarried counterparts even after adjusting for differential effects of marriage by nativity. The findings reveal that perceived discrimination is detrimental to the physical health of both Puerto Rican and Mexican Americans, but that the stress-buffering effect of marriage on physical health exists for Mexican Americans only.

    2011-03-01

    To discover whether Latino Puerto Rican and non-Latino communities differ in the words they use to talk about Alzheimer's disease (AD). Four groups of 30 persons per group defined by self-identified ethnicity and caregiver status: Latino Puerto Ricans and non-Latino Whites, who were either caregivers or non-caregivers completed free-listing exercises to identify the words they use when they describe AD causes, symptoms, caregiving, and research risks and benefits. Both Latino Puerto Ricans and non-Latino Whites recognize AD as a disease of memory loss and other cognitive problems. Although both groups used the term "sadness" to describe AD, non-Latino Whites did not feature emotional, behavioral, or psychological problems as among the causes of AD. Although all the groups' descriptions of a person who lives with and cares for a person with AD shared the word "loving," Latino Puerto Ricans focused on a good spouse who exercises intelligence, patience, and attention on behalf of the person with AD and did not use the term "caregiver." In contrast, non-Latino Whites typically used the term "caregiver." Both groups' lists shared words that describe research as presenting harms to an AD patient and requiring a commitment of time. Latino Puerto Ricans' lists suggested an understanding of research benefits akin to clinical care. Notable differences exist in how Latino Puerto Ricans and non-Latino Whites talk about AD and AD research. Clinicians, clinical investigators, and patient educators need to consider these differences when they conduct clinical care and research and design outreach and educational materials.

    Bond, V

    1997-01-01

    Fieldwork on a commercial farm in southern Zambia, which was aimed at designing an HIV prevention program for farm workers, gradually exposed the nature of sexual liaisons between young girls, coming to work on the farm from the surrounding villages, and older migrant men workers. Before completing fieldwork, the anthropologist voiced her concern about the implications of these liaisons for the spread of STDs and HIV with the local rural community, farm management and farm workers. The immediate outcome of her intercessions was the decision by management to sack under-age workers. Although some members of the local community, including local research assistants, and some managers and workers welcomed this decision, others were angered by it. Caught between interest groups and conflicting guidelines, the anthropologist, it is argued, was in a no-win situation, 'between a rock and a hard place'. The paper proposes that the application of anthropological ethics in AIDS research needs some re-evaluation.

    2012-01-01

    Failure to comply with requirements for proper storage and use of pesticides in farms can be extremely hazardous and the risk of accidents involving farm workers, other persons and even animals is high. There are still wide differences in the interpretation of the concept of "securing or making safe", by workers in this sector. One of the critical points detected, particularly in the fruit sector, is the establishment of an adequate storage site for plant protection products. The definition of "safe storage of pesticides" is still unclear despite the recent enactment of Legislative Decree 81/2008 regulating health and work safety in Italy. In addition, there are no national guidelines setting clear minimum criteria for storage of plant protection products in farms. The authors, on the basis of their professional experience and through analysis of recent legislation, establish certain minimum safety standards for storage of pesticides in farms.

    Full Text Available Poverty alleviation and environmental preservation are very important issues to many governments. Alley farming is beneficial to the environment because it conserves soil and sustains yields over time. Specifically, alley farming reduces soil erosion, which is a major problem in Thailand. Alley farming was conducted on a farmer’s field at Khaokwan Thong, a village in Uthaithani Province, Northern Thailand. We did a two-by-two factorial with and without alley farming, and with and without fertilizer. From this study, we observed that the two species used, Leucaena leucocephala and Acacia auriculiformis, grow well in Thailand, and that alley farming is suitable for Thailand. Few Thai farmers have heard about alley farming. However, it is nevertheless useful to know that there is potential for alley farming in Thailand using the two species. These plants, based upon the diameter and height measurements provided, grew well.

    To document the natural course of sensation seeking from childhood to adolescence, characterize distinct sensation seeking trajectories, and examine how these trajectories vary according to selected predictors. Data were obtained from the Boricua Youth Study, a longitudinal study of 2,491 children and adolescents of Puerto Rican background (3 assessments from 2000 to 2004). First, age-specific sensation seeking levels were characterized, and then age-adjusted residuals were analyzed using growth mixture models. On average, sensation seeking was stable in childhood (ages 5-10 years) and increased during adolescence (ages 11-17 years). Mean scores of sensation seeking were higher in the South Bronx versus Puerto Rico and among males versus females. Four classes of sensation seeking trajectories were observed: most study participants had age-expected sensation seeking trajectories following the average for their age ("normative," 43.8%); others (37.2%) remained consistently lower than the expected average for their age ("low" sensation seeking); some (12.0%) had an "accelerated" sensation seeking trajectory, increasing at a faster rate than expected; and a minority (7.0%) had a decreasing sensation seeking trajectory that started high but decreased, reaching scores slightly higher than the age-average sensation seeking scores ("stabilizers"). Site (South Bronx versus Puerto Rico) and gender were predictors of membership in a specific class of sensation seeking trajectory. It is important to take a developmental approach when examining sensation seeking and to consider gender and the social environment when trying to understand how sensation seeking evolves during childhood and adolescence.

    López, Irene

    2008-04-01

    This exploratory study investigated whether ethnic identity, as assessed by Phinney's (1992) Multigroup Ethnic Identity Measure, functioned as a moderator in the relation between skin color (as measured by masked interviewer evaluation, participant self-report, and skin reflectance data) and self-esteem (as measured by Rosenberg's 1989 Self-Esteem Scale). In a sample of 53 English-speaking Puerto Rican women, a hierarchical multiple regression indicated that among lighter skinned women, those who felt less attached to their culture had less self-esteem than those who were more culturally embedded. Similarly, among darker skinned women, greater attachment to Puerto Rican culture was associated with greater self-esteem than a less defined ethnic identity. Findings are discussed in light of the beneficial effects of ethnic identity.

    Clopidogrel is by far the most prescribed platelet adenosine diphosphate (ADP) antagonist in Puerto Rico despite the advent of newer agents (prasugrel and ticagrelor). Given the paucity of data on clopidogrel responsiveness in Hispanics, we sought to determine the association between clinical characteristics and platelet reactivity in Puerto Rican patients on clopidogrel therapy. A total of 100 Puerto Rican patients on clopidogrel therapy were enrolled and allocated into two groups: Group I, without high on-treatment platelet reactivity (HTPR); and Group II, with HTPR. Platelet function was measured ex vivo using the VerifyNow® P2Y12 assay. The cohort was comprised of Hispanic patients with coronary artery disease (57%), peripheral artery disease (32%), carotid artery stenosis (7%), cerebral artery aneurysm (2%), and stroke (2%). Mean platelet reactivity was 200 ± 61 P2Y12 reaction units (PRUs) (range: 8-324), and 35% of patients had HTPR (PRUs ⩾ 230). Multivariable logistic regression analysis determined that diabetes mellitus (DM) [odds ratio (OR) = 3.27; 95% confidence interval (CI): 1.20-8.96], use of proton-pump inhibitors (PPIs) (OR = 3.60; 95% CI: 1.09-11.82), and calcium channel blockers (CCBs) (OR = 3.10; 95% CI: 1.09-8.83) were independent predictors of HTPR ( p Puerto Rican Hispanic patients on clopidogrel, 35% had HTPR. Furthermore, DM, PPIs and CCBs predicted HTPR. Clinical outcome data are needed to identify appropriate PRU thresholds for risk prediction in the Puerto Rican population.

    2015-12-01

    The Puerto Rican parrot ( Amazona vittata ) has become an iconic and high-profile conservation species. The cornerstone of the recovery plan for this critically endangered species is an active captive breeding program, management of the wild population, and a long-term reintroduction program. In 2002, 40 adult Puerto Rican parrots that had not produced viable offspring were selected for reproductive assessment at 2 aviary populations in Puerto Rico (Iguaca and Río Abajo), which are the only sources of parrots for release. The goal was to enhance reproductive potential and produce productive pairings in an attempt to augment the population growth and provide ample individuals for reintroduction. Seven Hispanolian Amazon parrots ( Amazona ventralis ) that were used as surrogate parents for the Puerto Rican parrots were also included in the study. This assessment included physical examination, endoscopic evaluation, hematologic and plasma biochemical profiles, viral screening, and hormonal assays. Results of general physical examination and hematologic and plasma biochemical testing revealed overall good health and condition of this subset of the population of Puerto Rican parrots; no major infectious diseases were found. Endoscopic examination also revealed overall good health and condition, especially of females. The apparent low fertility of male birds warrants further investigation. The findings helped to define causes of reproductive failure in the selected pairs and individual birds. New pairings resulting from the assessment helped to augment reproduction of this critically endangered species.

    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.

    Historically, osteoporosis has not been considered a public health priority for the Hispanic population. However, recent data indicate that Mexican Americans are at increased risk for this chronic condition. Although it is well established that there is heterogeneity in social, lifestyle, and health-related factors among Hispanic subgroups, there are currently few studies on bone health among Hispanic subgroups other than Mexican Americans. The current study aimed to determine the prevalence of osteoporosis and low bone mass (LBM) among 953 Puerto Rican adults, aged 47 to 79 years and living on the US mainland, using data from one of the largest cohorts on bone health in this population: The Boston Puerto Rican Osteoporosis Study (BPROS). Participants completed an interview to assess demographic and lifestyle characteristics and bone mineral density measures. To facilitate comparisons with national data, we calculated age-adjusted estimates for osteoporosis and LBM for Mexican American, non-Hispanic white, and non-Hispanic black adults, aged ≥50 years, from the National Health and Nutrition Examination Survey (NHANES). The overall prevalence of osteoporosis and LBM were 10.5% and 43.3% for participants in the BPROS, respectively. For men, the highest prevalence of osteoporosis was among those aged 50 to 59 years (11%) and lowest for men ≥70 years (3.7%). The age-adjusted prevalence of osteoporosis for Puerto Rican men was 8.6%, compared with 2.3% for non-Hispanic white, and 3.9% for Mexican American men. There were no statistically significant differences between age-adjusted estimates for Puerto Rican women (10.7%), non-Hispanic white women (10.1%), or Mexican American women (16%). There is a need to understand specific factors contributing to osteoporosis in Puerto Rican adults, particularly younger men. This will provide important information to guide the development of culturally and linguistically tailored interventions to improve bone health in this

    Oquendo-Rodriguez, Aida L.

    Professions and careers related to science and mathematics lack representation of minorities. Within these underrepresented minority populations there is no other group more affected than Latina women and girls. Women in general, are still underrepresented in many areas of our society. While women's roles are changing in today's society, most changes encourage the participation of more White/Anglo women in traditionally male roles. Latina women are still more disadvantaged than White women. There is no doubt that education is significant in increasing the participation of minorities in the fields of science and mathematics, especially for minority girls (Oakes, 1990; Rodriguez, 1993). This study explored the interests, life experiences, characteristics and motivations of Latina girls of Puerto Rican origin who are successful in science and mathematics high school courses. The study identifies factors that can influence the interest of Latina girls of Puerto Rican origin in science and mathematics career choices. This research is significant and relevant to educators and policy makers, especially to science and mathematics educators. The research is primarily descriptive and exploratory. It explores the social characteristics of Latina girls and professional women who have been successful in science and mathematics high school courses. The research offers the reader a visit to the participants' homes with descriptions and the opportunity to explore the thoughts and life experiences of Latina girls, their mothers and young Latina professionals of Puerto Rican origin. This research reveals the common characteristics of successful students found in the Latina girls of Puerto Rican origin who where interviewed.

    Adolescents from Puerto Rican backgrounds are found to have higher rates of obesity than adolescents from other ethnic groups in the US. The objective of this study is to examine whether sleeping the recommended number of hours and depression or anxiety disorder are independently related to risk for obesity in a sample of Island Puerto Rican adolescents, and whether the association between sleep and obesity is moderated by depression or anxiety disorder. Data from the study were derived from the third wave of an island wide probability sample of Puerto Rican youth residing on the Island, 10-25 years of age (N = 825), with a response rate of 79.59%. The current study focuses on youth 10 to 19 years of age (n = 436). In this sample, youth who slept less than the recommended number of hours (defined as 7-9 h per night) had a significantly increased risk for obesity and were three times as likely to be obese. Youth who met criteria for a depressive/anxiety disorder were almost 2.5 times as likely to be obese. However, the presence of an anxiety/depressive disorders did not moderate the association between sleeping the recommended number of hours and risk for obesity. Sleeping less than the recommended number of hours may be an important risk factor for obesity status in Island Puerto Rican youth. These findings suggest that attention to healthy sleep behaviors and a sleep environment that promotes high quality sleep may be important for Puerto Rican adolescents at risk for obesity.

    Espinosa-Gongora, Carmen; Larsen, Jesper; Moodley, Arshnee

    Background: Methicillin-resistant Staphylococcus aureus (MRSA) CC398 is non-typeable by standard pulsed-field gel electrophoresis (PFGE) due to methylation of the SmaI site. This makes it difficult to study the epidemiology of this livestock-associated MRSA clone. In this study, we employed...... a recently developed PFGE protocol using Cfr9I, a neoschizomer of SmaI, to investigate the diversity of MRSA CC398 in Danish pig farms. The PFGE profiles displayed by isolates from pigs, environmental samples and farm workers were compared in order to understand whether farms are contaminated with multiple...... MRSA CC398 sublineages and whether specific sublineages may occur on different farms. Methods: A cross sectional study was performed in five Danish pig farms where farm workers had been shown to carry MRSA CC398 in the previous year. A total of 75 environmental and 308 animal samples were collected...

    Among the Hispanic community, Puerto Ricans have the highest prevalence of asthma and manifest the worst outcomes. The expected growth of the Hispanic population in the USA in the next several decades make elimination of disparate care in Puerto Rican asthmatics a matter of national importance. The purpose of this review of the literature (ROL) is to examine a variety of health system, genetic and cultural barriers in the Puerto Rican community which have created disparities in asthma care and outcomes among adult and pediatric Hispanic populations. In addition, this ROL describes several culturally sensitive, community-based educational interventions which can be used as a framework for future projects to improved asthma outcomes. Databases searched included Medline, PubMED, EBSCOhost, PsycINFO, CINAHL, Google Scholar and ERIC. Papers published in English from January 1990 to January 2012 were reviewed. Health system policies, insurer compensation patterns, clinician attitudes and cultural values/folk remedies in the Puerto Rican community represent barriers to effective asthma management, the use of controller medication and the implementation of educational interventions. In addition, genetic factors involving the beta-2 adrenergic receptor gene, which impair the response to albuterol, appear to contribute to poorer outcomes in Puerto Rican asthmatics. In contrast, several comprehensive, community-based, culturally sensitive educational interventions such as Controlling Asthma in American Cities Project (CAACP), the Racial and Ethnic Approach to Community Health in the US Program and Healthy Hoops programs (REACH) have been described. We believe that culturally sensitive community-based asthma education programs can serve as models for programs targeted toward Puerto Ricans to help decrease asthma morbidity. Moreover, greater sensitivity to Puerto Rican mores and folk remedies on the part of healthcare providers may improve the patient-clinician rapport and

  3. Coping with the work constraints in crop-livestock farming systems

    Full Text Available This research aims to characterize the ways crop-livestock farms adapt themselves to work constraints. A follow-up of work activities was achieved in a sample of 14 family farms. Work times in each agricultural activity (livestock and crops were quantified, distinguishing the contributions of family members and that of the off-farm workers. Results showed that the annual working time averaged 1030 days per year per farm. It increased with multiple activities within farms. Work devoted to livestock averaged 581 days a year, mainly achieved by family members, while crops necessitated 449 days of work, mostly assumed by off farm workers. Farms with limited arable land devoted significant time to livestock. The results also revealed that the gross incomes from one day of work in livestock were almost 50-times less than those from the same duration in cash crops. Altogether, the results confirm the necessity to consider work as a crucial variable determining farming systems’ performances and the use efficiency of this input. As a consequence, in many developing countries, the assumption of plenty of family workers availability may not be valid anymore to justify agricultural policies mainly based on intense on-farm work uses.

    2000-03-01

    The purpose of this study was to evaluate the epidemiologic patterns of breast cancer and to estimate the lifetime risk probability of developing breast cancer among Hispanic females using cancer data from Puerto Rico. The age-adjusted breast cancer incidence rate (per 100,000) in Puerto Rico increased from 15.3 in 1960-1964 to 43.3 in 1985-1989. The age-adjusted breast cancer mortality rate (per 100,000) increased from 5.7 to 10.6 comparing the same two time periods (1960-1964 vs 1985-1989). Nevertheless, in 1985-1989 breast cancer incidence rate was higher in US White females (110.8 per 100,000) compared to Puerto Rican females (51.4 per 100,000; age-adjusted to the 1970 US standard population). The breast cancer mortality rate was also higher in US White females (27.4 per 100,000) than in Puerto Rican females (15.1 per 100,000; age-adjusted to the 1970 US standard population) during 1985-1989. A multiple decrement life table was constructed applying age-specific incidence and mortality rates from cross-sectional data sets (1980-1984 and 1985-1989 data for Puerto Rican females and 1987-1989 SEER data sets for US White and Black females) to a hypothetical cohort of 10,000,000 women. The probability of developing invasive breast cancer was computed for the three groups using the long version of DEVCAN: Probability of DEVeloping CANcer software, version 3.3. The lifetime risk of developing breast cancer was 5.4% for Puerto Rican females, compared to 8.8% for US Black females and 13.0% for US White females. Lifetime risk for Puerto Rican females increased from 4.5% in 1980-1984 to 5.4% in 1985-1989. Lifetime risk of breast cancer appears to be increasing in Puerto Rico, but remains lower than the probability for US White females. Therefore, the application of lifetime probability of developing invasive breast cancer estimated for the US female population will overestimate the risk for the Puerto Rican female population.

  8. Ecosystem-Level Carbon Stocks in Costa Rican Mangrove Forests

    Cifuentes, M.

    2012-12-01

    Tropical mangroves provide a wide variety of ecosystem services, including atmospheric carbon sequestration. Because of their high rates of carbon accumulation, the large expected size of their total stocks (from 2 to 5 times greater than those of upland tropical forests), and the alarming rates at which they are being converted to other uses (releasing globally from 0.02 to 0.12 Pg C yr-1), mangroves are receiving increasing attention as additional tools to mitigate climate change. However, data on whole ecosystem-level carbon in tropical mangroves is limited. Here I present the first estimate of ecosystem level carbon stocks in mangrove forests of Central America. I established 28, 125 m-long, sampling transects along the 4 main rivers draining the Térraba-Sierpe National Wetland in the southern Pacific coast of Costa Rica. This area represents 39% of all remaining mangroves in the country (48300 ha). A circular nested plot was placed every 25 m along each transect. Carbon stocks of standing trees, regeneration, the herbaceous layer, litter, and downed wood were measured following internationally-developed methods compatible with IPCC "Good Practice Guidelines". In addition, total soil carbon stocks were determined down to 1 m depth. Together, these carbon estimates represent the ecosystem-carbon stocks of these forests. The average aboveground carbon stocks were 72.5 ± 3.2 MgC ha-1 (range: 9 - 241 MgC ha-1), consistent with results elsewhere in the world. Between 74 and 92% of the aboveground carbon is stored in trees ≥ 5cm dbh. I found a significant correlation between basal area of trees ≥ 5cm dbh and total aboveground carbon. Soil carbon stocks to 1 m depth ranged between 141 y 593 MgC ha-1. Ecosystem-level carbon stocks ranged from 391 MgC ha-1 to 438 MgC ha-1, with a slight increase from south to north locations. Soil carbon stocks represent an average 76% of total ecosystem carbon stocks, while trees represent only 20%. These Costa Rican mangroves

  9. Modelling the smart farm

    2017-09-01

    Full Text Available Smart farming envisages the harnessing of Information and Communication Technologies as an enabler of more efficient, productive, and profitable farming enterprises. Such technologies do not suffice on their own; rather they must be judiciously combined to deliver meaningful information in near real-time. Decision-support tools incorporating models of disparate farming activities, either on their own or in combination with other models, offer one popular approach; exemplars include GPFARM, APSIM, GRAZPLAN amongst many others. Such models tend to be generic in nature and their adoption by individual farmers is minimal. Smart technologies offer an opportunity to remedy this situation; farm-specific models that can reflect near real-time events become tractable using such technologies. Research on the development, and application of farm-specific models is at a very early stage. This paper thus presents an overview of models within the farming enterprise; it then reviews the state-of the art in smart technologies that promise to enable a new generation of enterprise-specific models that will underpin future smart farming enterprises.

  10. Hand safety for specialty crop production workers: a pilot study investigating frequencies of minor open-wound hand injuries and presence of pathogenic bacteria.

    2013-10-01

    The purpose of this study was to quantify the presence of minor open-wound hand injuries in addition to Salmonella, Staphylococcus aureus, coliforms, and Escherichia coli on the hands of farm workers who hand-harvest fruit crops in Utah. Data collection was conducted on four farms without USDA Good Agricultural Practices (GAP) certification and on two farms with GAP certification. This study identified essential safety issues that need to be addressed for improving the effectiveness of safety training for migrant farm workers. Farms that have a food safety audit program in place are less likely to have farm workers exposed to pathogenic bacteria and open-wound injuries to their hands. High frequency of S. aureus may indicate a potentially higher risk for wound infection within this worker population. This could lead to infections that are resistant to the antibiotics commonly used to treat ordinary staph infections, resulting in greater work loss time and medical expenses for these workers. Higher frequencies of bacterial presence on workers' hands on non-certified farms indicate a need to identify essential practices to improve worker hygiene habits and on-farm management practices to promote healthy hygiene. Open-wound injuries to migrant farm workers during hand-harvesting could create additional health problems with the possibility of infection and the spread of diseases. Continued research is needed to understand workers' acceptance of these injuries and barriers to personal protection.

    2009-12-01

    Among Latino adults and children, ataques de nervios has been associated with an array of psychiatric disorders. Using data from a probability sample of Puerto Rican children, aged 5 to 13 years (N = 2491), we assessed the lifetime prevalence and psychiatric correlates of ataques in youth residing in the South Bronx, New York and San Juan, Puerto Rico. Baseline site comparisons indicated that between 4% and 5% of children had a lifetime prevalence of ataques (either by child or parent report) and that ataques were associated with greater global impairment and a host of childhood disorders within the previous twelve months. Ataques were also correlated with greater exposure to violence, as well as more stressful life events for the South Bronx sample. After controlling for several covariates, ataques continued to be significantly associated with psychopathology. Ataques are, therefore, a significant correlate of global impairment and childhood psychopathology among Puerto Rican youth.

    This qualitative research project explores how poverty, the built environment, education, working conditions, health care access, food insecurity and perceived discrimination are experienced by Puerto Rican Latinas through the course of their lives. Five focus groups were conducted with the primary objective of documenting community experiences and perspectives regarding: 1) stress, including perceived discrimination based on race/ethnicity (racism); 2) the impact of stress on Puerto Rican women of reproductive age, their families, and/or their community; and 3) stressors that affect maternal health. Focus groups were conducted in English and Spanish in the two cities with the highest rates of premature birth and low infant birthweight in the state of Connecticut. Focus group findings indicate that participants perceived poverty, food insecurity, lack of access to quality education, and unsafe environments as significant life stressors affecting maternal and child health.

    People living with HIV/AIDS are stigmatized. Although personal and social consequences of this stigmatization have been documented, research regarding its impact on social interactions is scarce. Latinos, and Puerto Ricans in particular, have voiced concern regarding AIDS stigma. The authors investigated the key role of social interaction in the process of stigmatization through in-depth, semistructured interviews in a sample of 30 Puerto Ricans living with HIV/AIDS. Participants reported instances in which AIDS stigma negatively influenced social interactions with family, friends, sexual partners, coworkers, and health professionals. Some of the consequences they described were loss of social support, persecution, isolation, job loss, and problems accessing health services. Findings support the need for interventions to address AIDS stigma and its consequences.

    2006-12-01

    We assessed the impact of diabetes in a large Puerto Rican community of Chicago by measuring the prevalence of diagnosed diabetes and calculating the diabetes mortality rate. Data were analyzed from a comprehensive health survey conducted in randomly selected households in community areas. Questions on diagnosed diabetes and selected risk factors were asked. In addition, vital records data were analyzed in order to calculate the age-adjusted diabetes mortality rate. When possible, rates were compared to those found in other studies. The diabetes prevalence located in this community (20.8%: 95% CI = 10.1%-38.0%) is the highest ever reported for Puerto Ricans and one of the highest ever reported in the United States for a non-Native American population. For instance, it is twice the prevalence for Puerto Ricans in New York (11.3%) and Puerto Rico (9.3%-9.6%). Diagnosed diabetes was found to be significantly associated with obesity (p = 0.023). The prevalence was particularly high among older people, females, those born in the US, and those with a family history of diabetes. Notably, the diabetes mortality rate (67.6 per 100,000 population) was more than twice the rate for all of Chicago (31.2) and the US (25.4). Understanding why the diabetes prevalence and mortality rates for Puerto Ricans in this community are so much higher than those of other communities is imperative for primary and secondary prevention. Collaboration between researchers, service providers and community members can help address the issues of diabetes education, early screening and diagnosis, and effective treatment needed in this community.

    Introduction Latina mothers play a central role in raising and socializing their children; however, few studies have examined the cultural, socio-cognitive and neighborhood-related variables influencing the level of communication between Puerto Rican mothers and their children about sexuality and sexual health. This cross-sectional study sought to examine these influences. Methods Puerto Rican mothers with children aged 10-19 years (n = 193) were selected randomly for an ethnographic interview as part of a community participatory action research project in a U.S. urban northeastern community. Results Bivariate analyses found statistically significant associations between the child's age (p = 0.002), the mother's past communication about traditional gender role norms of women (marianismo) (p < 0.001), her positive outcome expectations for communications with her child (p < 0.025), and her perceptions of the physical condition (p < 0.001) and sexual health problems (p = 0.047) in the neighborhood. In a multivariate model, all of these variables remained significant except sexual health problems, and mother's attitudes toward the obligations of children to parents (familismo) emerged as a factor associated with a decrease in the number of sexual health topics that mothers raised with their children. No significant effects were found for mother's spiritual and religious experience (religiosidad). Discussion Our study highlights the importance of marianismo as a framework within which Puerto Rican mothers communicate sexual health information as well as the need to improve mothers' confidence discussing sexual health issues with their children. Future public health interventions to promote communication about sexuality and sexual health among Puerto Rican mothers should consider addressing this issue as a part of comprehensive neighborhood improvement projects.

Given the urgency of preserving and restoring the surface water bodies, and facing the need of defining a monitoring tool to classify surface water pollution, the Costa-Rican WRF relies on two water quality indexes: the so-called "Dutch Index" (D.I) and the Biological Monitoring Working Party adapted to Costa Rica (BMWP'CR), allowing an "easy" physicochemical and biological appraisal of the water quality and the ecological integrity of water bodies. Herein, we intend to evaluate whether the compound of water quality indexes imposed by Costa Rican legislation, is suitable to assess rivers local and global anthropogenic pressure and environmental conditions. We monitor water quality for 7 points of Liberia River (northern pacific region - Costa Rica) from March 2013 to July 2015. Anthropogenic pressures are characterized by catchment land use and riparian conditions. Environmental conditions are built from rainfall daily series. Our results show (i) the difficulties to monitor new sites following the recent implementation of the WRF; (ii) the statistical characteristics of each index; and (iii) a modelling tentative of relationships between water quality indexes and explanatory factors (land-use, riparian characteristics and climate conditions).

    Latinas have high overall breastfeeding initiation rates, yet Puerto Ricans have among the lowest exclusive breastfeeding rates. This study sought to determine if acculturation was associated with intent to breastfeed in a predominantly Puerto Rican population. A cohort of Latina women were enrolled in Proyecto Buena Salud, and provided information on infant feeding intent (n = 1,323). Acculturation was assessed via the Psychological Acculturation Scale (PAS), language preference, and generation in the United States. Increasing acculturation as measured by English language preference (aOR 0.61 [95% CI 0.42-0.88]) and second or third generation in the United States (aOR 0.70 [95% CI 0.52-0.95)] was inversely associated with odds of intending to exclusively breastfeed. Similarly, women with higher levels of acculturation as measured by the PAS (aOR 0.67 [95% CI 0.45-0.99]), English language preference (aOR 0.48 [95% CI 0.33-0.70]) and second or third generation in the United States (aOR 0.42 [95% CI 0.31-0.58]) were less likely to report intent to combination feed as compared with women with lower acculturation. Acculturation was inversely associated with intent to exclusively breastfeed and intent to combination feed in this predominantly Puerto Rican sample. © 2015 Wiley Periodicals, Inc.

  6. The social basis of separatism: explaining support for the Puerto Rican Independence Movement

    Full Text Available In the 1990s, particularly in the wake of the fall of the Soviet Union, comparativists rediscovered the enduring appeal of separatist movements around the globe. Many of the most significant political events of the past decade have revolved around issues of nationalism, ethnicity, irredenta, and the like. In light of these renewed preoccupations, it is surprising that U.S. scholars have largely ignored a nationalist movement closer to home. The Puerto Rican independence movement is by far the most significant separatist tendency under the U.S. flag, and is one of the few major anticolonialist movements to survive into the twenty-first century. Although supporters of Puerto Rican independence have typically drawn only three to five percent support in local elections and in plebiscites on the island’s political status, neither have they disappeared from the political scene. The remarkable durability of the independence movement demands systematic explanation. However, as strange as it may seem, to date there have been no serious scholarly studies of the social bases of the Puerto Rican independence movement.

    The Puerto Rican parrot was reduced to 13 animals in 1975 and as a conservation measure, a captive population was established from a few founders taken from the wild between 1973 and 1983. The number of successful breeding pairs in captivity has been !ow, and the captive breeding program has not been as productive as that of the closely related Hispaniolan parrot. Therefore, a genetic study was initiated to examine the relative levels of relatedness of the captive founders using levels of bandsharing in DNA fingerprints. Unrelated captive founder Puerto Rican parrots had the same average level of bandsharing (0.41) as second-degree relatives of the Hispaniolan parrot (0.38, P > 0,05), with an inbreeding coefficient of 0.04. High levels of bandsharing (>40%) between pairs of males and females correlated with reproductive failure, suggesting that inbreeding depression is partly responsible for the !ow number of' breeding pairs. Consequently, DNA profiling can be used to guide the captive breeding program for the Puerto Rican parrot, and other endangered species, by identifying pairs of males and females with low levels of bandsharing.

    Introduction Latina mothers play a central role in raising and socializing their children; however, few studies have examined the cultural, socio-cognitive and neighborhood-related variables influencing the level of communication between Puerto Rican mothers and their children about sexuality and sexual health. This cross-sectional study sought to examine these influences. Methods Puerto Rican mothers with children aged 10–19 years (n = 193) were selected randomly for an ethnographic interview as part of a community participatory action research project in a U.S. urban northeastern community. Results Bivariate analyses found statistically significant associations between the child’s age (p = 0.002), the mother’s past communication about traditional gender role norms of women (marianismo) (p communications with her child (p communicate sexual health information as well as the need to improve mothers’ confidence discussing sexual health issues with their children. Future public health interventions to promote communication about sexuality and sexual health among Puerto Rican mothers should consider addressing this issue as a part of comprehensive neighborhood improvement projects.

    There is growing and compelling evidence demonstrating the extra-skeletal role of vitamin D and the importance of maintaining adequate levels of this nutrient. Currently, there is very limited information available on the vitamin D status in children and adults in underserved groups, including Puerto Ricans. We assessed the vitamin D status of 4,090 Puerto Ricans living in six geographical regions in the island. Only 31.5% of the studied population had sufficient vitamin D levels (>30 ng/ml). The 18-39 year age group and the females showed inadequate (<30 ng/ml) levels of vitamin D (76.9% and 69.8%, respectively). Participants aged 60 or older showed the highest mean values of serum 25(OH)D (28.8 ng/ml) and the highest percentage (37.1%) of sufficient levels (>30 ng/ml). Future studies are certainly warranted to understand the prevalence of vitamin D deficiency and influencing factors (including obesity) in Puerto Ricans.

  10. Artificial Cavities and Nest Site Selection by Puerto Rican Parrots: a Multiscale Assessment

    2006-12-01

    Full Text Available We examined nest site selection by Puerto Rican Parrots, a secondary cavity nester, at several spatial scales using the nest entrance as the central focal point relative to 20 habitat and spatial variables. The Puerto Rican Parrot is unique in that, since 2001, all known nesting in the wild has occurred in artificial cavities, which also provided us with an opportunity to evaluate nest site selection without confounding effects of the actual nest cavity characteristics. Because of the data limitations imposed by the small population size of this critically endangered endemic species, we employed a distribution-free statistical simulation approach to assess site selection relative to characteristics of used and unused nesting sites. Nest sites selected by Puerto Rican Parrots were characterized by greater horizontal and vertical visibility from the nest entrance, greater density of mature sierra palms, and a more westerly and leeward orientation of nest entrances than unused sites. Our results suggest that nest site selection in this species is an adaptive response to predation pressure, to which the parrots respond by selecting nest sites offering advantages in predator detection and avoidance at all stages of the nesting cycle. We conclude that identifying and replicating the “nest gestalt” of successful nesting sites may facilitate conservation efforts for this and other endangered avian species.

  11. Association of Types of Life Events with Depressive Symptoms among Puerto Rican Youth.

    Graciela Jaschek

    Full Text Available The main objective of this study was to examine the association between four types of adverse life events (family environment, separation, social adversity, and death and the development of depressive symptoms among Puerto Rican youth. This was a secondary analysis using three waves (2000-2004 of interview data from the Boricua Youth Study of 10-13 year old Puerto Rican youth residing in New York and Puerto Rico with no depressive symptoms at baseline (n = 977. Depressive symptoms increased with an increase in social adversity, separation, death, and death events. Youth support from parents was a significant protective factor for all adverse events and parent coping was a protective factor in social adversity events. Relying on standard diagnostic tools is ideal to identify youth meeting the criteria for a diagnosis of depression but not useful to detect youth who present with subclinical levels of depression. Youth with sub-clinical levels of depression will not get treated and are at increased risk of developing depression later in life. Adverse life events are potentially relevant to use in conjunction with other screening tools to identify Puerto Rican youth who have subclinical depression and are at risk of developing depression in later adolescence.

In addition to the numerical simulations, measured data have been analyzed in order to provide the basis for a full-scale verification of the model performance. The basic idea behind...... the DWMmodel is to model the in- stationary wind farm flow characteristics by considering wind turbine wakes as passive tracers continuously emitted from the wind farm turbines each with a downstream transport pro- cess dictated by large scale turbulent eddies (lateral and ver- tical transportation; i.......e. meandering) and Taylor advection. For the present purpose, the DWM model has been im- plemented in the aeroelastic code HAWC2 [1], and the per- formance of the resulting model complex is mainly verified by comparing simulated and measured loads for the Dutch off-shore Egmond aan Zee wind farm [2].

    Full Text Available Data Farming is a process that has been developed to support decision-makers by answering questions that are not currently addressed. Data farming uses an inter-disciplinary approach that includes modeling and simulation, high performance computing, and statistical analysis to examine questions of interest with a large number of alternatives. Data farming allows for the examination of uncertain events with numerous possible outcomes and provides the capability of executing enough experiments so that both overall and unexpected results may be captured and examined for insights. Harnessing the power of data farming to apply it to our questions is essential to providing support not currently available to decision-makers. This support is critically needed in answering questions inherent in the scenarios we expect to confront in the future as the challenges our forces face become more complex and uncertain. This article was created on the basis of work conducted by Task Group MSG-088 “Data Farming in Support of NATO”, which is being applied in MSG-124 “Developing Actionable Data Farming Decision Support for NATO” of the Science and Technology Organization, North Atlantic Treaty Organization (STO NATO.

    The siting of wind farms is becoming an increasingly important issue in the Netherlands. This paper gives an overview of the current situation concerning the planning of wind farms. We will pay attention to: Wind energy in official Dutch planning policy. To select the optimal sites, the government has made an administrative agreement with the 7 windy provinces. Nevertheless, wind energy is still fighting for a rightful position in physical planning policy. Some examples will illustrate this. Studies on siting and siting problems in the Netherlands. In order to gain more insight into aspects of wind farming several studies have been executed. In this paper special attention will be paid to the results of a study on the potential impact of large windturbine clusters on an existing agricutural area. Experiences with siting of wind farms in the Netherlands. Based on experiences with the planning and realization of farms, this paper gives the main problems. In the final part of the paper we present some general conclusions. Generally speaking, the knowledge is available for selecting optimal sites in the Netherlands. The basic problems for wind farming nowadays seem to be the visual impact and actually obtaining the ground. Nevertheless, there do seem to be enough sites for realizing the goals in the Netherlands.

    2007-11-01

    A whole-farm dairy model was developed and evaluated. The DairyWise model is an empirical model that simulated technical, environmental, and financial processes on a dairy farm. The central component is the FeedSupply model that balanced the herd requirements, as generated by the DairyHerd model, and the supply of homegrown feeds, as generated by the crop models for grassland and corn silage. The output of the FeedSupply model was used as input for several technical, environmental, and economic submodels. The submodels simulated a range of farm aspects such as nitrogen and phosphorus cycling, nitrate leaching, ammonia emissions, greenhouse gas emissions, energy use, and a financial farm budget. The final output was a farm plan describing all material and nutrient flows and the consequences on the environment and economy. Evaluation of DairyWise was performed with 2 data sets consisting of 29 dairy farms. The evaluation showed that DairyWise was able to simulate gross margin, concentrate intake, nitrogen surplus, nitrate concentration in ground water, and crop yields. The variance accounted for ranged from 37 to 84%, and the mean differences between modeled and observed values varied between -5 to +3% per set of farms. We conclude that DairyWise is a powerful tool for integrated scenario development and evaluation for scientists, policy makers, extension workers, teachers and farmers.

    Full Text Available This article emphasizes the strategic and operations aspects of managing a farm. In this article, farm management performance is analyzed based on yearly Illinois Farm Business Farm Management (FBFM panel data across 9,831 farms from 1996 through 2014. The alpha scores (or skill estimates for farm managers are analyzed to determine if most profitable farmers possess specific skills or knowledge against adverse events in a volatile environment. Farms are evaluated under different scenarios of management skill portfolios. Fundamental farm management basics are discussed in this study, including budgeting, production planning, financial analysis, financial management, investment analysis, and control management. We find substantial difference of farm management styles and performance efficiency in management skill portfolios. We also find evidence of most skilled farm managers are more efficient on both revenue side and costs side. The approaches used in this study also allow comparison among farms of different sizes and types. The activities of top farms can be replicated by poorer performers and the study provide a unique way for comparing the farm management styles and ability of most skilled farm managers to that of less skilled ones. The innovative method is framed by comparing business strategies and performance styles in the following aspects: production and operations planning, land management and control, and production costs evaluation. Farm managers will want to consult it as well to improve the effectiveness, objectivity, and success of their decisions.

    This article describes the development of the Certified Safe Farm (CSF) on-farm safety review tools, characterizes the safety improvements among participating farms during the study period, and evaluates differences in background variables between low and high scoring farms. Average farm review scores on 185 study farms improved from 82 to 96 during the five-year study (0-100 scale, 85 required for CSF certification). A total of 1292 safety improvements were reported at an estimated cost of $650 per farm. A wide range of improvements were made, including adding 9 rollover protective structures (ROPS), 59 power take-off (PTO) master shields, and 207 slow-moving vehicle (SMV) emblems; improving lighting on 72 machines: placing 171 warning decals on machinery; shielding 77 moving parts; locking up 17 chemical storage areas, adding 83 lockout/tagout improvements; and making general housekeeping upgrades in 62 farm buildings. The local, trained farm reviewers and the CSF review process overall were well received by participating farmers. In addition to our earlier findings where higher farm review scores were associated with lower self-reported health outcome costs, we found that those with higher farm work hours, younger age, pork production in confinement, beef production, poultry production, and reported exposure to agrichemicals had higher farm review scores than those who did not have these characteristics. Overall, the farm review process functioned as expected. encouraging physical improvements in the farm environment, and contributing to the multi-faceted CSF intervention program.

    OSHA inspection of dairy farms began in July 1, 2014 in New York State. As of September 2014, a total of eight farms were randomly selected for inspection. This case study addresses how dairy farm managers prepared for these inspections, and identifies farm level costs preparing for inspection and/or being inspected. Four farms that were OSHA inspected and 12 farms that were not inspected were included in this mixed method evaluation using a multimodal (telephone, email, or mail) survey. Descriptive analysis was carried out using frequencies, proportions, means, and medians. Overall, the impact of OSHA inspections was positive, leading to improved safety management and physical changes on the farm and worker trainings, although the farmers' perspectives about OSHA inspection were mixed. The cost of compliance was low relative to estimated overall production costs. Clarifications and engineering solutions for specific dairy farm hazard exposures are needed to facilitate compliance with OSHA regulations. © 2015 Wiley Periodicals, Inc.

We look at what questions they have been used to answer, the advantages and pitfalls of the methods, and how future research can best use these approaches to answer some of the most important upcoming questions in farm animal welfare. Abstract The use of models in the life sciences has greatly expanded in scope and advanced in technique in recent decades. However, the range, type and complexity of models used in farm animal welfare is comparatively poor, despite the great scope for use of modeling in this field of research. In this paper, we review the different modeling approaches used in farm animal welfare science to date, discussing the types of questions they have been used to answer, the merits and problems associated with the method, and possible future applications of each technique. We find that the most frequently published types of model used in farm animal welfare are conceptual and assessment models; two types of model that are frequently (though not exclusively) based on expert opinion. Simulation, optimization, scenario, and systems modeling approaches are rarer in animal welfare, despite being commonly used in other related fields. Finally, common issues such as a lack of quantitative data to parameterize models, and model selection and validation are discussed throughout the review, with possible solutions and alternative approaches suggested.

    Introduction Latinas in the United States on average have poorer birth outcomes than Whites, yet considerable heterogeneity exists within Latinas. Puerto Ricans have some of the highest rates of adverse outcomes and are understudied. The goal of this study was to determine if acculturation was associated with adverse birth outcomes in a predominantly Puerto Rican population. Methods We conducted a secondary analysis of Proyecto Buena Salud, a prospective cohort study conducted from 2006 to 2011. A convenience sample of pregnant Latina women were recruited from a tertiary care hospital in Massachusetts. Acculturation was measured in early pregnancy; directly via the Psychological Acculturation Scale, and via proxies of language preference and generation in the United States. Birth outcomes (gestational age and birthweight) were abstracted from medical records (n = 1362). Results After adjustment, psychological acculturation, language preference, and generation was not associated with odds of preterm birth. However, every unit increase in psychological acculturation score was associated with an increase in gestational age of 0.22 weeks (SE = 0.1, p = 0.04) among all births. Women who preferred to speak Spanish (β = -0.39, SE = 0.2, p = 0.02) and who were first generation in the US (β = -0.33, SE = 0.1, p = 0.02) had significantly lower gestational ages than women who preferred English or who were later generation, respectively. Similarly, women who were first generation had babies who weighed 76.11 g less (SE = 35.2, p = 0.03) than women who were later generation. Discussion We observed a small, but statistically significant adverse impact of low acculturation on gestational age and birthweight in this predominantly Puerto Rican population.

    Full Text Available Brain-derived neurotrophic factor (BDNF has been associated with regulation of body weight and appetite. The goal of this study was to examine the interactions of a functional variant (rs6265 in the BDNF gene with dietary intake for obesity traits in the Boston Puerto Rican Health Study. BDNF rs6265 was genotyped in 1147 Puerto Rican adults and examined for association with obesity-related traits. Men (n=242 with the GG genotype had higher BMI (P=0.009, waist circumference (P=0.002, hip (P=0.002, and weight (P=0.03 than GA or AA carriers (n=94. They had twice the risk of being overweight (BMI≥25 relative to GA or AA carriers (OR = 2.08, CI = 1.02–4.23, and P=0.043. Interactions between rs6265 and polyunsaturated fatty acids (PUFA intake were associated with BMI, hip, and weight, and n-3 : n-6 PUFA ratio with waist circumference in men. In contrast, women (n=595 with the GG genotype had significantly lower BMI (P=0.009, hip (P=0.029, and weight (P=0.027 than GA or AA carriers (n=216. Women with the GG genotype were 50% less likely to be overweight compared to GA or AA carriers (OR = 0.05, CI = 0.27–0.91, and P=0.024. In summary, BDNF rs6265 is differentially associated with obesity risk by sex and interacts with PUFA intake influencing obesity traits in Boston Puerto Rican men.

    This paper examines the relationship between self-reliance (preference to solve emotional problems on one's own) and 5 mental healthcare utilization outcomes for Puerto Ricans living in low-income areas. A random probability community sample of noninstitutionalized Puerto Ricans, ages 18-69, living in low-income areas of the island were selected and interviewed in 1992-93 and 1993-94. A series of logistic regression models tested the association between self-reliance and 5 mental health utilization measures, after adjusting for covariates measuring predisposing, enabling, need and barrier factors: any use of mental health services, any use of general health services for mental healthcare, any use of specialty care, use of psychotropic medications, and retention in mental healthcare. Self-reliance was found to be negatively associated with all 5 dependent service utilization measures. Those with a positive self-reliant attitude were 40% less likely to use care on any of the 5 outcome measures. An interaction was also observed between definite need for mental healthcare and having a self-reliant attitude when predicting mental health service use. Definite needers with a self-reliant attitude were 54%-58% less likely to use mental health services compared with definite needers who did not have a self-reliant attitude. Further, decreases in self-reliant attitude over the two data collection periods were associated with increases in mental health service use. Our findings suggest that self-reliance is a significant and robust predictor of mental healthcare utilization among Puerto Ricans living in low-income areas of the island.

    This article compares multiple types of child maltreatment among Puerto Rican youth. We seek to expand the limited knowledge of the effects of multiple types of maltreatment on depressive symptoms in a specific Latino population as emerging studies indicate that children who are exposed to one type of maltreatment are often exposed to other types. This study examines the predictive strength of different and multiple types of lifetime child maltreatment (i.e., physical, sexual, and emotional abuse; and neglect), and the effect of youth support from parents, youth coping, youth self-esteem, and place of residence on depressive symptoms among Puerto Rican youth. Secondary data analyses were performed using three annual waves (2000-2004) of data from the Boricua Youth Study. The analytic sample consists of 1041 10-13 year old Puerto Rican youth living in New York and Puerto Rico. Results indicate that: (1) youth who experienced 'sexual abuse only', 'multiple maltreatment' (2 or more types of maltreatment), 'physical abuse only' have a significant increase in depressive symptoms (75.1%, 61.6%, and 40.5% respectively) compared to those without maltreatment; and (2) place of residence, exposure to violence, and mental disorders were significant risk factors. When developing psychosocial interventions, professionals should particularly focus on youth who report past lifetime experience with child maltreatment. Particular attention should be given to children living in the Bronx, New York and similar urban low-income areas who report past lifetime experience with multiple types of child maltreatment and who present symptoms or a diagnosis of co-occurring mental health problems.

    Full Text Available The relative contributions of genetics and environment to asthma in Hispanics or to asthma in children younger than 3 years are not well understood.To examine the relative contributions of genetics and environment to early-childhood asthma by performing a longitudinal twin study of asthma in Puerto Rican children ≤ 3 years old.678 twin infants from the Puerto Rico Neo-Natal Twin Registry were assessed for asthma at age 1 year, with follow-up data obtained for 624 twins at age 3 years. Zygosity was determined by DNA microsatellite profiling. Structural equation modeling was performed for three phenotypes at ages 1 and 3 years: physician-diagnosed asthma, asthma medication use in the past year, and ≥ 1 hospitalization for asthma in the past year. Models were additionally adjusted for early-life environmental tobacco smoke exposure, sex, and age.The prevalences of physician-diagnosed asthma, asthma medication use, and hospitalization for asthma were 11.6%, 10.8%, 4.9% at age 1 year, and 34.1%, 40.1%, and 8.5% at 3 years, respectively. Shared environmental effects contributed to the majority of variance in susceptibility to physician-diagnosed asthma and asthma medication use in the first year of life (84%-86%, while genetic effects drove variance in all phenotypes (45%-65% at age 3 years. Early-life environmental tobacco smoke, sex, and age contributed to variance in susceptibility.Our longitudinal study in Puerto Rican twins demonstrates a changing contribution of shared environmental effects to liability for physician-diagnosed asthma and asthma medication use between ages 1 and 3 years. Early-life environmental tobacco smoke reduction could markedly reduce asthma morbidity in young Puerto Rican children.

    We describe the impact of war on Puerto Rican Veterans and family members. We used qualitative research methods to collect and analyze data. We interviewed 8 Veterans and 8 family members. We used the constant comparison method to review data to identify prominent themes. Two categories emerged: (1) Challenges associated with post-deployment family reintegration, and (2) A positive aftermath of war on the family. Overall, findings indicate that OEF/OIF Veterans and family members were not prepared for the changes they encounter post-deployment. Despite these challenges, some Veterans and family members strengthened their relationships and renewed their appreciation for one another.

    This article is a case study of a Puerto Rican adolescent with suicidal behavior. The adolescent began a Socio-Cognitive Behavioral Therapy for Suicidal Behavior (SCBT), an ambulatory treatment, after being hospitalized for a suicide attempt. The SCBT incorporates an ecological and developmental perspective to CBT. She initially presented low self-esteem, and significant depressive and anxiety symptoms. At the end of treatment, the adolescent revealed a significant change in symptoms, and a better use of her coping skills. No suicidal ideation was presented during previous months, neither during follow up. Case analysis allowed treatment protocol modifications, particularly family sessions and communication skills, thus contributing to its further feasibility.

    A 3 cm diameter mass from the metacarpus of a Puerto Rican Amazon parrot was diagnosed as a granular cell tumour based on light microscopy. The cytoplasmic granules were periodic-acid Schiff positive and diastase resistant. Ultrastructural characteristics of the cells included convoluted nuclei and the presence of numerous cytoplasmic tertiary lysosomes. This is only the second granular cell tumour reported in a bird. We speculate that most granular cell tumours are derived from cells that are engaged in some type of cellular degradative process, creating a similar morphologic appearance, but lacking a uniform histogenesis.

    Full Text Available Enteric parasitosis remains an important public health problem in many areas around the world including in Brazil, and it is frequently associated with poverty and lack of sanitation facilities. Research carried out over the course of a year revealed that 96.6% (28/29 of children randomly selected from a 'landless farm workers' settlement in Araras, São Paulo, aged 4 - 15 years, presented Giardia intestinalis cysts. After referral to the neighborhood Health Office, all the children received tinidazole, given as a single dose of 50 mg/kg and 12 months later, new fecal samples were collected and analyzed. Despite the low adherence to the study, a high percentage (64.3% - 9/14 of the children remained positive for the parasite. This study showed a high positivity of giardiasis in child residents of the settlement, even after treatment; adults were not sensitized to the study and did not collected and/or deliver children fecal samples. The precarious living conditions are consistent with a high susceptibility to parasitic diseases, suggesting that the treatment of the infected individuals without identifying and eradicating the means of contamination is simply a palliative measure.Enteroparasitoses continuam a ser um importante problema de saúde pública em muitas áreas ao redor do mundo, bem como no Brasil, e está frequentemente associada com a pobreza e à falta de saneamento básico.

    Full Text Available Nowadays, agriculture has become one of the most important fields of activity, significant funds being allotted within the EU budget to finance the European agriculture. In this context, organising the accounting of economic entities which carry out their activity in the agricultural sector has acquired new meanings. The goal of the present study is to bring into the light the particularities of the farm accounting on two levels: on the one hand, from the perspective of the international accounting referential and, on the other hand, in compliance with the national accounting regulations. The most important conclusion of this work is that, in post-1990 Romania, no interest was further manifested for the refinement of aspects specific to farm accounting.

    Studies have found that major depression and diabetes mellitus are strongly associated. The main goal of this study was to evaluate the association between major depression and diabetes in a large medically indigent population of Puerto Rican adults living on the island. A secondary database analysis through a cross-sectional design was used for this study. Participants were selected from the Puerto Rico Commonwealth Health Plan database, beneficiaries of the public health sector. Adult's subjects with at least one claim during 2002 were included. The final sample consisted of 1,026,625 adult insured. The International Classification of Diseases (ICD-9) was used for disease classifications. The prevalence of diabetes was 14.6% in subjects with major depression and 9.7% for those without major depression (POR 1.59, p diabetes appears to be significantly higher in Puerto Rican adults with major depression compared to those without this psychiatric disorder. Longitudinal prospective studies and randomized controlled trials are needed to shed light on the temporal or causal relationship and to test whether effective prevention and treatment can reduce the risk of developing diabetes.

    This study focuses on depression and substance use in Puerto Rican primary care patients, age 50 and older, recruited from five clinics in Hartford, CT (n = 303). One-third of the participants screened positive for depression using the Center for Epidemiologic Studies-Depression scale, and 16 percent either reported excessive alcohol use, prescription drug abuse, and/or illegal drug use in the past year. Correlates of depression include younger age, female gender, being separated or divorced, low perceived adequacy of income, poor health status, functional limitations, few emotional supports, and a history of an "ataque de nervios." Younger age, male gender, low perceived adequacy of income, few emotional supports, suicidal ideation, and a history of an "ataque de nervios" were associated with substance use. While the relationship between excessive alcohol use and a higher rate of depression did not reach statistical significance, drug use was a strong predictor of depression, particularly prescription drug abuse. However substance use did not significantly affect the likelihood of seeking treatment for depression. These findings underscore the need for appropriate interventions for those at risk for depression among the Puerto Rican population.

    Previous research has documented the association between the Latino cultural idiom of distress, ataques de nervios (i.e., "attacks of nerves"), and unexplained neurological symptoms among adults. However, the associations between ataques and somatic complaints in children have not been sufficiently explored. In this study, we assessed the relation between this anxiety-related experience, henceforth ataques, and somatic complaints in a probability sample of Puerto Rican youth, ages 5-13 years, living in San Juan, Puerto Rico (N = 1353) and in the South Bronx, New York (N = 1138). When both sites were combined, children with ataques were significantly more likely to have either a lifetime prevalence of asthma or headaches, and tended to have more stomach aches and a history of epilepsy or seizure than children without ataques. Further within site analyses showed a similar patterning of complaints for the South Bronx sample as for the combined sample. However, children in San Juan with ataques were only slightly more likely to experience headaches, and at risk for injury, than those without ataques. In addition, comparisons between ataque sufferers across sites indicated that children in San Juan with ataques were at elevated risk for serious illness or injury in comparison to those in the South Bronx with ataques. Ataques are significantly associated with a wide range of physical complaints in Puerto Rican youth. However, their pattern of associations differs by context. © 2010 Blackwell Publishing Ltd.

    2003-09-01

    This paper is about naming illnesses--about who determines what categories are used and the implications of these determinations. The central concerns of medical/psychiatric anthropology have been to understand popular categories of and systems for classification of illness, to examine the relationship of illness categories to cultural understandings of the body, and to interpret the role of categories of illness in mediating between the personal and social spheres. At the same time, the paper also discusses the interplay of popular categories and psychiatric diagnoses. This paper examines the multiple experiences of nervios among Puerto Ricans in Puerto Rico and New York City. Our contention is that nervios is more than a diffuse idiom of distress, and that there are different categories and experiences of nervios which provide insights into how distress is experienced and expressed by Puerto Ricans and point to different social sources of suffering. The data in this paper come from the responses to a series of open-ended questions which tapped into people's general conceptions of nervios and ataques de nervios. These questions were incorporated into follow-up interviews to an epidemiological study of the mental health of adults in Puerto Rico. The results suggest ways to incorporate these different categories of nervios into future research and clinical work with different Latino groups in the United States and in their home countries.

    Todorova, Irina L G; Tejada, Shirley; Castaneda-Sceppa, Carmen

    Puerto Ricans are the second largest Hispanic group in the U.S. and older adults have significant health disparities. Educational programs that address heart disease risk for this population have rarely been developed and implemented. To address this gap, the Heart Healthy Initiative for Puerto Rican adults is being developed. To develop it as a participatory program, the community members were asked about their perspectives. Five focus groups with 28 participants, aged 45-60, were conducted, transcribed and analyzed using Thematic Analysis. In-depth analysis of meanings of health promoting behaviors, in the context of cultural beliefs and values was carried out. The following themes were identified: Health as balance and integration; Health as connection of self, connection with others; Cultural meanings of lifestyle choices; Stresses and struggles. Participants suggested that the program should have significant variety and a holistic perspective, be sensitive to different needs and motivations, stimulate mutual understanding and shared cultural meanings. The program needs to support lifestyle changes which maximally preserve traditions and to introduce multi-level changes. The identified cultural meanings of diet, physical activity and relationships were taken into account to develop the educational curriculum.

Adolescents and parents were recruited from socioeconomically diverse populations in rural and urban areas of San José, Costa Rica. Subjects were 92 adolescents (14 to 17 years old) and 48 parents. Focus group data were transcribed and entered into the qualitative data analysis software Atlas.ti version 5.0. Analyses were grounded on the social cognitive theory. Five themes emerged from the focus group discussions: (1) Costa Rican adolescents associate the consumption of moderate quantities of healthy foods with femininity and male homosexuality. (2) The consumption of hearty portions of nonhealthy foods was associated with masculinity and male heterosexuality. (3) There is an emerging view that it is acceptable for heterosexual male adolescents to take care of their bodies through healthy eating. (4) Body care among female adolescents is an element of femininity and body image. (5) Parents reinforce their daughters' persistent concern with weight control because they perceive it as feminine behavior. Health promoters should be aware of the existing and changing food stereotypes around gender as an avenue for the promotion of healthy eating.

    Dengue virus (DENV) nucleic acid amplification testing of blood donations during epidemics in endemic locations, including Puerto Rico, has suggested possible sizable transfusion transmission risk. Estimates of the long-term prevalence of DENV viremic donations will help evaluate the potential magnitude of this risk in Puerto Rico. Estimates of the prevalence of DENV viremia in the Puerto Rican population at large from 1995 through 2010 were derived from dengue case reports and their onset dates obtained from islandwide surveillance, estimates of case underreporting, and extant data on the duration of DENV viremia and the unapparent-to-apparent dengue infection ratio. Under the assumptions that viremia prevalence in blood donors was similar to that of the population at large and that symptomatic persons do not donate, statistical resampling methods were used to estimate the prevalence of dengue viremia in blood donations. Over the 16-year period, the maximum and mean daily prevalences of dengue viremia (per 10,000) in blood donations in Puerto Rico were estimated at 45.0 (95% confidence interval [CI], 36.5-55.4) and 7.0 (95% CI, 3.9-10.1), respectively. Prevalence varied considerably by season and year. These data suggest a substantial prevalence of DENV viremia in Puerto Rican blood donations, particularly during outbreaks. © 2012 American Association of Blood Banks.

    Despite the large number of studies, mostly in developed economies, there is limited consensus on the health effects of inequality. Recently a related literature has examined the relationship between relative deprivation and health as a mechanism to explain the economic inequality and health relationship. This study evaluates the relationship between mortality and economic inequality, as measured by area-level Gini coefficients, as well as the relationship between mortality and relative deprivation, in the context of a middle-income country, Costa Rica. We followed a nationally representative prospective cohort of approximately 16,000 individuals aged 30 and over who were randomly selected from the 1984 census. These individuals were then linked to the Costa Rican National Death Registry until Dec. 31, 2007. Hazard models were used to estimate the relative risk of mortality for all-cause and cardiovascular disease mortality for two indicators: canton-level income inequality and relative deprivation based on asset ownership. Results indicate that there was an unexpectedly negative association between canton income inequality and mortality, but the relationship is not robust to the inclusion of canton fixed-effects. In contrast, we find a positive association between relative deprivation and mortality, which is robust to the inclusion of canton fixed-effects. Taken together, these results suggest that deprivation relative to those higher in a hierarchy is more detrimental to health than the overall dispersion of the hierarchy itself, within the Costa Rican context.

    The objective of this study was to estimate the prevalence of current asthma and the proportion of current asthma that is related to work on the farm among primary farm operators. The 2011 Farm and Ranch Safety Survey data were used to produce estimates and prevalence odds ratios. An estimated 5.1% of farm operators had asthma. Of these, 15.4% had farm work-related asthma. Among operators with farm work-related asthma, 54.8% (95% confidence interval [CI]: 41.8%-68.2%) had an asthma attack in the prior 12 months and 33.3% (95% CI: 21.2%-45.4%) had an asthma attack that occurred while doing farm work. Of those who had an asthma attack that occurred while doing farm work, 65.0% associated their asthma attack with plant/tree materials. This study provides updated information on asthma and the proportion of current asthma that is related to work on the farm and identifies certain groups of farm operators that might benefit from workplace asthma prevention intervention.

    Older Puerto Rican adults have particularly high risk of diabetes compared to the general US population. Diabetes is associated with both higher depressive symptoms and cognitive decline, but less is known about the longitudinal relationship between cognitive decline and incident depressive symptoms in those with diabetes. This study investigated the association between cognitive decline and incident depressive symptoms in older Puerto Rican adults with diabetes over a four-year period. Households across Puerto Rico were visited to identify a population-based sample of adults aged 60 years and over for the Puerto Rican Elderly: Health Conditions study (PREHCO); 680 participants with diabetes at baseline and no baseline cognitive impairment were included in analyses. Cognitive decline and depressive symptoms were measured using the Mini-Mental Cabán (MMC) and Geriatric Depression Scale (GDS), respectively. We examined predictors of incident depressive symptoms (GDS ≥ 5 at follow-up but not baseline) and cognitive decline using regression modeling. In a covariate-adjusted logistic regression model, cognitive decline, female gender, and greater diabetes-related complications were each significantly associated with increased odds of incident depressive symptoms (p Puerto Ricans with diabetes who also experienced cognitive decline. Efforts are needed to optimize diabetes management and monitor for depression and cognitive decline in this population.

    Full Text Available It is no secret the racism within the Costa Rican society especially against people of African descent. While this racism is manifested in mostly overt ways it is nonetheless present, and continues to affect people of African descent in a myriad of ways including how they feel about their natural hair. From a very early age Afro-Costa Rican children learn to look down on their natural kink reinforced verbally and through images designed for them to hide, and dislike what is naturally theirs. As a result many embraced synthetic, and other ethnic group’s natural hair, preferring to pay any amount of money besides undergoing significant hair, and scalp ill-treatment all with the objective of hiding the natural kink. The main objective of this paper is to make visible the perceptions of Afro-Costa Ricans natural hair by both Afro, and mestizo ethnic groups, and enquire about some of the effects on people of African descent in Costa Rica. The exploratory research collected data from four focus groups of teenage mestizos, 20th century newspaper, one workshop, and questionnaires filled only by Afro-Costa Ricans.

    Full Text Available The use of models in the life sciences has greatly expanded in scope and advanced in technique in recent decades. However, the range, type and complexity of models used in farm animal welfare is comparatively poor, despite the great scope for use of modeling in this field of research. In this paper, we review the different modeling approaches used in farm animal welfare science to date, discussing the types of questions they have been used to answer, the merits and problems associated with the method, and possible future applications of each technique. We find that the most frequently published types of model used in farm animal welfare are conceptual and assessment models; two types of model that are frequently (though not exclusively based on expert opinion. Simulation, optimization, scenario, and systems modeling approaches are rarer in animal welfare, despite being commonly used in other related fields. Finally, common issues such as a lack of quantitative data to parameterize models, and model selection and validation are discussed throughout the review, with possible solutions and alternative approaches suggested.

  19. Occupational health care of radiation exposed workers

    The medical problems encountered by the earlier pioneer workers in radiation at the turn of the century are well known. In the 1928, the ICRP (International Committee for Radiological Protection) was instituted and the ALARA principle of radiation protection was evolved. Occupational health care is about maintaining the health and safety of workers in their workplaces. This involves using medical, nursing and engineering practices to achieve its objectives. In certain occupations, including those where workers are exposed to ionising radiation, some of these principles are enshrined in the legislation and would require statutory compliance. Occupational health care of radiation workers seek to prevent ill health arising from exposure to radiation by consolidating the benefits of exposures control and dosimetry. This is via health surveillance for spillages, contamination and exposures to unsealed sources of radiation. It is unlikely that can plan and hope to cater for a Chernobyl type of disaster. However, for the multitude of workers in industry exposed to radiation, control models are available. These are from the more in industrialize countries with a nuclear based energy industry, and where radioactive gadgetry are used in places ranging from factories and farms to construction sites. These models involve statutory requirements on the standard of work practices, assessment of fitness to work and the monitoring of both the worker and the workplace. A similar framework of activity is present in Malaysia. This will be further enhanced with the development of her general health and safety at work legislation. (author)

    Full Text Available [i][/i]Introduction and objective. Reduced asthma and allergy risks in farmers have been ascribed to microbial exposures. However, selection may also play a role and this was assessed in two Scandinavian farming populations. Materials and methods. Asthma prevalence in 739 Danish farming students was compared to that of 1,105 siblings. 8,482 Norwegian farmers were also compared with 349 early retired farmers. Results. The prevalence of ever-asthma was 5.4% in farming students and 5.2% in siblings (OR 1.1; 95%CI 0.73–1.7. Current asthma in farmers was 3.0% compared to 6.3% in farmers who had retired early (OR 1.8, 95%CI 1.1–2.9. Adjustments for early retirement increased the asthma prevalence by 0.3–0.6%. Farmers who had changed production were more likely to have asthma (OR 9.8, 95% CI 6.0–16. Conclusions. No healthy worker selection into farming was observed and changes in asthma prevalence due to early retirement were small. Selection effects are therefore unlikely to explain the protective effects of farming on asthma.

  1. Are large farms more efficient? Tenure security, farm size and farm efficiency: evidence from northeast China

    How to increase production efficiency, guarantee grain security, and increase farmers' income using the limited farmland is a great challenge that China is facing. Although theory predicts that secure property rights and moderate scale management of farmland can increase land productivity, reduce farm-related costs, and raise farmer's income, empirical studies on the size and magnitude of these effects are scarce. A number of studies have examined the impacts of land tenure or farm size on productivity or efficiency, respectively. There are also a few studies linking farm size, land tenure and efficiency together. However, to our best knowledge, there are no studies considering tenure security and farm efficiency together for different farm scales in China. In addition, there is little study analyzing the profit frontier. In this study, we particularly focus on the impacts of land tenure security and farm size on farm profit efficiency, using farm level data collected from 23 villages, 811 households in Liaoning in 2015. 7 different farm scales have been identified to further represent small farms, median farms, moderate-scale farms, and large farms. Technical efficiency is analyzed with stochastic frontier production function. The profit efficiency is regressed on a set of explanatory variables which includes farm size dummies, land tenure security indexes, and household characteristics. We found that: 1) The technical efficiency scores for production efficiency (average score = 0.998) indicate that it is already very close to the production frontier, and thus there is little room to improve production efficiency. However, there is larger space to raise profit efficiency (average score = 0.768) by investing more on farm size expansion, seed, hired labor, pesticide, and irrigation. 2) Farms between 50-80 mu are most efficient from the viewpoint of profit efficiency. The so-called moderate-scale farms (100-150 mu) according to the governmental guideline show no

    Through regulations, permitting or binding negotiations, Regulators establish requirements, limits, permit conditions and Notice of Construction (NOC) conditions with which the Office of River Protection (ORP) and the Tank Farm Contractor (TFC) must comply. Operating Specifications are technical limits which are set on a process to prevent injury to personnel, or damage to the facility or environment, The main purpose of this document is to provide specification limits and recovery actions for the TFC Environmental Surveillance Program at the Hanford Site. Specification limits are given for monitoring frequencies and permissible variation of readings from an established baseline or previous reading. The requirements in this document are driven by environmental considerations and data analysis issues, rather than facility design or personnel safety issues. This document is applicable to all single-shell tank (SST) and double-shell tank (DST) waste tanks, and the associated catch tanks and receiver tanks, and transfer systems. This Tank Farm Environmental Specifications Document (ESD) implements environmental-regulatory limits on the configuration and operation of the Hanford Tank Farms facility that have been established by Regulators. This ESD contains specific field operational limits and recovery actions for compliance with airborne effluent regulations and agreements, liquid effluents regulations and agreements, and environmental tank system requirements. The scope of this ESD is limited to conditions that have direct impact on Operations/Projects or that Operations Projects have direct impact upon. This document does not supercede or replace any Department of Energy (DOE) Orders, regulatory permits, notices of construction, or Regulatory agency agreements binding on the ORP or the TFC.

    Although individual healthy lifestyle behaviors may reduce cardiovascular disease risk, few studies have analyzed the combined effect of multiple lifestyle components as one all-inclusive measure on such outcomes, much less in minority populations. We aimed to develop a Healthy Lifestyle Score (HLS) that included several lifestyle recommendations and to test its association with metabolic syndrome (MetS) and allostatic load (AL) and their cardiometabolic and neuroendocrine factors in Puerto Ricans. In a cross-sectional study in 787 Puerto Ricans living in Boston (aged 45-75 y), we developed an HLS that ranged from 0 to 190 (higher score indicative of healthier lifestyle) and included 5 components (diet, physical activity and sedentary behaviors, smoking, social support and network, and sleep). Multivariable-adjusted models were used to test associations between the HLS and biomarkers of dysregulation and odds of MetS and high AL (≥4 out of 10 components). The HLS showed adequate internal consistency (ρ = 0.31-0.69) and was inversely associated with urinary cortisol (β ± SE = -0.22 ± 0.11; P = 0.042), epinephrine (-0.20 ± 0.09; P = 0.017), and norepinephrine (-0.26 ± 0.11; P = 0.016); waist circumference (-0.014 ± 0.004; P = 0.003); and serum insulin (-0.30 ± 0.13; P = 0.028) and positively associated with plasma HDL cholesterol (0.007 ± 0.003; P = 0.021) after adjustment for potential confounders. For each 20-unit increase in HLS, participants had 19% (95% CI: 2%, 33%) and 25% (11%, 36%) lower odds of MetS or AL, respectively. Healthier scores for social support and network and smoking components were associated with lower odds of high AL (P lifestyle components. Following an overall healthy lifestyle that comprises a combination of multiple behaviors may provide stronger protection against MetS and AL in Puerto Rican adults than individual components. The HLS may be a useful tool for examining health-related outcomes. This trial was registered at

    The factors which govern species‘ distribution and abundance are myriad, and together constitute the ecological niche of a given species. Because abiotic factors are arguably the most profound of the factors influencing niche boundaries and thus, species distributions, substantial changes in either climatic or habitat-related parameters can be expected to produce interrelated and profound niche shifts. Habitat loss and degradation can also effectively induce a de facto climate change by forcing populations to relocate to environmentally suboptimal habitats. Populations experiencing niche shifts due to range restrictions and geographic isolation become subject to a suite of factors that may act synergistically to amplify deleterious ecological effects of habitat loss. These factors tend to exert a greater influence on populations of rare or endemic species with inherently restricted ranges. The Puerto Rican parrot (Amazona vittata) is an example of a tropical, insular, endemic and critically-endangered species that has suffered from extensive habitat loss and degradation over the past century, resulting in a single relict wild population restricted for more than 70 years to the montane rainforest of the Luquillo Mountains in northeastern Puerto Rico. In this chapter, we examine the current ecological situation of this geographically and demographically isolated parrot population by reviewing the history of landscape-level changes in and around the Luquillo Mountains, and concurrent biotic and abiotic limiting factors in relation to both historical population trajectory and current prognosis for species recovery. We used a decade (2000-2009) of empirical data on parrot fledgling survival together with long-term climatological data to model effects of local climate on fledgling survival and gain insights into its influence on population growth. We also modeled hypothetical survival of parrot fledglings in the lowlands surrounding the Luquillo Mountains, areas

    Full Text Available Abstract Background Variations in gene allele frequencies can contribute to differences in the prevalence of some common complex diseases among populations. Natural selection modulates the balance in allele frequencies across populations. Population differentiation (FST can evidence environmental selection pressures. Such genetic information is limited in Puerto Ricans, the second largest Hispanic ethnic group in the US, and a group with high prevalence of chronic disease. We determined allele frequencies and population differentiation for 101 single nucleotide polymorphisms (SNPs in 30 genes involved in major metabolic and disease-relevant pathways in Puerto Ricans (n = 969, ages 45–75 years and compared them to similarly aged non-Hispanic whites (NHW (n = 597. Results Minor allele frequency (MAF distributions for 45.5% of the SNPs assessed in Puerto Ricans were significantly different from those of NHW. Puerto Ricans carried risk alleles in higher frequency and protective alleles in lower frequency than NHW. Patterns of population differentiation showed that Puerto Ricans had SNPs with exceptional FST values in intronic, non-synonymous and promoter regions. NHW had exceptional FST values in intronic and promoter region SNPs only. Conclusion These observations may serve to explain and broaden studies on the impact of gene polymorphisms on chronic diseases affecting Puerto Ricans.

    The study investigated the associations between mental health and measures of community support, social support networks, sense of place, adversity, and perceived problems in a rural Australian population. There was a specific focus on farming communities due to previous qualitative research by the authors indicating distress by farmers in response to drought (Sartore et al. Aust Fam Phys 36(12), 990-993, 2007). A survey was mailed to adults randomly selected from the Australian Electoral Roll and residing within four local government areas (LGAs) of varying remoteness in rural New South Wales (NSW). Survey measures included: support networks and community attachment; recent stressors (including drought-related stress); and measures of health and related functioning. The Kessler-10 provided an index of current psychological distress. The sample (n = 449; response rate 24%) was predominantly female (58.4%) and 18.9% were farmers or farm workers. Moderate to very high psychological distress was reported for 20.7% of the sample. Half (56.1%) of all respondents, and specifically 71.8% of farmers or farm workers, reported high levels of perceived stress due to drought. Psychological distress was associated with recent adverse life events, increased alcohol use and functional impairment. Hierarchical regression analysis demonstrated an independent effect of the number of stressful life events including drought related stress, perceived social support (community and individual), alcohol use and physical functioning ability on levels of psychological distress. This model accounted for 43% of the variance in current levels of distress. Lower community support had a more marked impact on distress levels for non-farming than farming participants. This study has highlighted the association between unique rural community characteristics and rural stressors (such as drought) and measures of mental health, suggesting the important mediating role of social factors and community

    This study examined the relationships of dissociation and childhood trauma with ataque de nervios. Forty Puerto Rican psychiatric outpatients were evaluated for frequency of ataque de nervios, dissociative symptoms, exposure to trauma, and mood and anxiety psychopathology. Blind conditions were maintained across assessments. Data for 29 female patients were analyzed. Among these 29 patients, clinician-rated dissociative symptoms increased with frequency of ataque de nervios. Dissociative Experiences Scale scores and diagnoses of panic disorder and dissociative disorders were also associated with ataque frequency, before corrections were made for multiple comparisons. The rate of childhood trauma was uniformly high among the patients and showed no relationship to dissociative symptoms and disorder or number of ataques. Frequent ataques de nervios may, in part, be a marker for psychiatric disorders characterized by dissociative symptoms. Childhood trauma per se did not account for ataque status in this group of female outpatients.

  12. Ataques de nervios in relation to anxiety sensitivity among island Puerto Ricans.

    2005-12-01

    This study investigated the symptom profile of ataques de nervios (ADN) among Puerto Rican volunteers from the community who self-identified as having experienced at least one ataque. As expected, the most commonly reported ataques-specific symptoms were crying, anger, nervousness, and becoming hysterical. Comparing the responses of those with ADN to those with no history of ADN but who reported elevated anxiety sensitivity (AS) indicated that both groups were comparable on measures of depression, state and trait anxiety, and associated panic symptoms. As expected, both groups scored significantly higher on all measures than did participants with no history of ADN and low AS with the exception of the measure of state anxiety. It is unclear, however, whether the overlap in symptom severity between those with ADN and those with elevated anxiety sensitivity indicates that ADN and AS are the same or distinct conditions.

  13. Experience of nervousness and anxiety disorders in Puerto Rican women: psychiatric and ethnopsychological perspectives.

    1989-01-01

    Analyses of case materials describe variations in the experiences of Puerto Rican women diagnosed as having an anxiety disorder, in treatment with mental health clinicians, physicians, or traditional healers. Their common complaints are examined as core symbolic elements in culturally patterned complexes of meanings focused around personal trauma, stressful life events, personal and social reactions, expectations about treatment, and the course of illness. Many of these women report themselves to be "nervous," to be "sick from nerves," or to have had an "ataque de nervios." "Nervousness" is the base symbolic domain in Puerto Rico of what psychiatry labels "anxiety disorder," although it is also a common complaint of many disorders. What "nervousness" means to patients/clients and their clinicians or healers is examined within the frames of multilayered popular and biomedical interpretations. The special difficulties of women in Puerto Rico are highlighted, and psychiatric and ethnopsychological (Spiritist) models of etiology and treatment are compared.

    2017-09-01

    Puerto Rican adolescents (N = 105; M age  = 15.97 years, SD = 1.40) evaluated hypothetical situations describing conflicts between Latino values (family obligations and respeto) and autonomy desires regarding personal, friendship, and dating activities. Adolescents judged that peers should prioritize Latino values over autonomy, which led to greater feelings of pride than happiness. However, they believed that teens would prioritize autonomy over Latino values, which led to greater feelings of happiness than pride. Adolescents reasoned about autonomy desires as personal issues, whereas reasoning about Latino values was multifaceted, including references to conventions and concerns for others. Furthermore, judgments and reasoning depended on the type of autonomy desire and Latino value and sometimes, by participants' age and sex. © 2016 The Authors.

  15. Anthropology in a postcolonial colony: Helen I. Safa's contribution to Puerto Rican ethnography.

    Science.gov (United States)

    Duany, Jorge

    2010-01-01

    This article assesses Helen I. Safa's legacy to anthropological thought in Puerto Rico. The first part of the article locates Safa's research on the Island within a long tradition of fieldwork by U.S. scholars since the early twentieth century. More recent research, conducted mostly by Puerto Rican women anthropologists and other social scientists, has expanded upon Safa's insights on gender and work. The second part of the essay analyzes Safa's major empirical work, The Urban Poor of Puerto Rico: A Study in Development and Inequality. Above all, this book helped overcome the theoretical impasse over the culture of poverty that characterized much of urban anthropology during the 1960s and 1970s. The article concludes with an appraisal of the relevance of Safa's work for the ethnography of contemporary Puerto Rico.

    Amphibians, turtles, mice and birds from a protected Costa Rican wildland were contaminated with organochlorine pesticides and metabolites. - Amphibians, turtles, birds (mostly passerines) and mice collected from a conservation area in northwestern Costa Rica were analyzed for organochlorine (OC) pesticide contamination. Six of 39 amphibians (three of eight species), three of six turtles (two species), one of eight mice (one species) and 19 of 55 birds (five of seven species) contained OCs at levels up to 580 ng/g. The most frequently detected compound in 23 of 108 organisms was p,p'DDE. Dieldrin, delta-BHC, heptachlor, p,p'DDD, and endosulfan II were each found in at least four organisms, while eight other OCs were found in at least one organism. The presence of OCs in taxa from the conservation area indicates the likelihood of long-distance transport of such compounds through the atmosphere.

    The Puerto Rican boa occurs in a variety of habitats, including wet montane forest, lowland wet forest, mangrove forest, wet limestone karst, and offshore cays, and from sea level to 480 m. Mean SVL of 49 encountered boas (live and road-killed) was 136.9 ?? 35.1 (range = 38.8-205 cm), with a mean mass of 952.1 ?? 349.0 g (n = 47; range = 140-1662 g). Prey in digestive tracts (n = 29) included remains of black rats, house mice, three species of anoles, bats, common ground-doves, domestic fowl chicks, and invertebrates. Females were in reproductive condition in late April through mid-August and had an average brood size of 21.8 ?? 6.0 (n = 9, range = 13-30 ).

    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.

    Full Text Available This paper analyzes the economic contribution of married and cohabiting women to the household income, in comparison to the income their partners generate, in Costa Rica.  From a perspective of gender roles, human capital theory and female labor participation, this paper examines what variables influence the probability of contribution.  Based on data by the 2014 National Household Survey, this study found that 51% percent of married or cohabiting women do not generate any income, which shows there is an unequal economic relationship in half of Costa Rican households and the males assume the breadwinning role.  Household chores and the number of children reduce the probability of economic contribution.  On the other hand, women with more years of schooling have a higher probability to contribute equally to the couple’s total income.

    The aim of the study was to determine the prevalence and factors associated with bursitis/tendonitis disorders in Puerto Ricans with diabetes mellitus (DM). A cross-sectional study was performed in 202 adult Puerto Ricans (100 DM patients and 102 non-diabetic subjects). For each participant, a complete medical history and a musculoskeletal exam were systematically performed. Socio-demographic parameters, health-related behaviors, comorbidities, and pharmacotherapy were determined for all subjects. For DM patients, disease duration, glycemic control, and DM long-term complications were also examined. Multivariate logistic regression analyses were used to determine the factors associated with bursitis/tendonitis disorders. The mean (SD) age for DM patients and non-diabetic controls were 53.3 (12.9) and 50.0 (13.1) years; 64.0 and 64.7 % of DM patients and controls were females, respectively. Overall, the prevalence of bursitis/tendonitis was higher in DM patients than among non-diabetics (59.0 % vs. 29.4 %, pdiabetics. Specifically, DM patients had a higher frequency of flexor tenosynovitis, De Quervain’s tenosynovitis, lateral epicondylitis, medial epicondylitis, trochanteric bursitis, and anserine bursitis than non-diabetic subjects (p<0.05). Among DM patients, multivariate analyses showed that those with bursitis/tendonitis were more likely to be female [OR (95 % CI) 4.55 (1.42, 14.55)] and have peripheral vascular disease [OR (95 % CI) 8.48 (1.71, 41.93)]. In conclusion, bursitis/tendonitis disorders were common in this population of Hispanics with DM. Among DM patients, bursitis/tendonitis disorders were more frequent in women and those with long-term complications such as peripheral vascular disease. PMID:24522480

    The relationship between multiple lifestyle components analyzed in combination and inflammation remains understudied. We aimed to assess the association between a Healthy Lifestyle Score (HLS) that includes adherence to five behavioral components (diet, physical activity and sedentary behaviors, smoking, social support and network, and sleep) and inflammatory markers, as well as the role of the HLS in inflammation among individuals with cardiometabolic conditions, in Puerto Rican adults. In a cross-sectional study of 842 Puerto Ricans adults (aged 45-75 y) living in Boston, MA, the HLS (range = 0-190; maximum indicative of healthiest adherence) was analyzed for association with three inflammatory markers: interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), and C-reactive protein (CRP). In multivariable-adjusted models, the HLS was inversely associated with IL-6 (β ± SE = -0.55 ± 0.13; P markers independently of the other HLS components. Significant inverse associations were observed for each 20-unit increase in HLS and IL-6 and TNF-α for participants with hypertension (n = 600; β ± SE = -0.58 ± 0.16; -0.46 ± 0.16, respectively) and with overweight/obesity (n = 743; β ± SE = -0.59 ± 0.13; -0.50 ± 0.14, respectively), but not for those with diabetes (n = 187) or heart disease (n = 192). The HLS was not associated with CRP, after adjustment for potential confounders. Higher adherence to multiple lifestyle behaviors was associated with lower concentrations of inflammatory markers. Because low-grade inflammation may precede chronic diseases, following an overall healthy lifestyle may help lower risk of these diseases.

    2018-05-17

    The available literature on ethnic identity among Puerto Ricans has focused on those living in the United States, with little to no attention placed on examining ethnic identity and psychological constructs among youth living in Puerto Rico. Using a colonial mentality framework, the current study examined the associations between ethnic identity, cultural stress, and self-concept among adolescent boys and girls living in Puerto Rico. The current cross-sectional study surveyed participants (N = 187) recruited from several junior high schools in the metropolitan area in Puerto Rico. Relations between ethnic identity, cultural stress, and self-concept differed by gender. First, cultural stress was associated with self-concept for boys, such that higher cultural stress predicted lower self-concept. Second, among girls, cultural stress moderated the relation between ethnic identity and self-concept. Specifically, for girls experiencing high cultural stress, exploration and resolution of their ethnic identity was associated with higher ratings of self-concept. Although cultural stress has been widely understood as a phenomena associated with immigrants, our study indicated that cultural stress is important in understanding self-concept of youth living in Puerto Rico. For boys, cultural stress, but not ethnic identity, is particularly important to their self-concept. Among girls experiencing high cultural stress, exploration and resolution of ethnic identity was associated with higher self-concept. Results suggested that the cultural stress associated with the colonial context of Puerto Rico is salient in ethnic identity and self-concept development, even though Puerto Rican youth are the ethnic majority in the island.

    Full Text Available Uno de los temas indagados en el Segundo estudio nacional realizado por el Observatorio Costarricense de Mipymes durante el 2011 corresponde al financiamiento de las micros, pequeñas y medianas empresas costarricenses. Se consultaron las fuentes de financiamiento más utilizadas, la presentación de solicitudes de crédito durante los últimos cinco años, la utilización que en general hacen estas empresas de los diferentes medios de financiamiento y sus requerimientos actuales. De forma similar a lo que ocurre en otros países, los fondos propios constituyen la principal opción para estas empresas. Por ello, en este trabajo han sido analizadas las condiciones que propician la autofinanciación o el uso de otras opciones. Por medio del análisis estadístico de la información recopilada en la encuesta, se comprueba que algunas variables relativas a la gestión empresarial, tales como la fuente de financiamiento inicial, la experiencia del (de la empresario(a y la prioridad que dan al manejo de aspectos financieros, presentan una asociación significativa con las estrategias de financiamiento en las mipymes costarricenses. ABSTRACT Financing was one of the areas investigated in the Second National Survey of micro, small and medium sized Costa Rican companies during 2011. The most used financing sources, credit applications during the last five years, end use of this credit, and current credit requirements in various financing institutions were investigated. Similar to other countries, own funding was the main option for these companies. Thus, this work examines the conditions that facilitate the use of self financing or other options available. Through statistic analysis of the information collected, variables like initial funding source, previous experience of the entrepreneur and priority given to financial management were shown to present a definite relationship to financing strategies for Costa Rican SMEs.

    OBJECTIVE AND MAIN OUTCOME MEASURES: This article provides 2005-2008 population-based prevalence data on obesity and overweight among youth residing in Puerto Rico. Data for this report are from the Asthma, Depression, and Anxiety in Puerto Rican Youth (ADA) study. Measures included height and weight level data on youth in Puerto Rico aged 10 to 19 years with and without asthma as well as body mass index data on their caregivers. A total of 436 youth-caregiver dyads were selected and weighted to represent the general population of youth in Puerto Rico using 2008 US Census data. Household surveys demonstrated that 40% of youth aged 10 to 19 were overweight or obese. Twenty-five percent met moderate-to-vigorous-intensity physical activity guidelines, however, physical activity was not associated with overweight or obesity in this sample. In multivariate analyses, females were 50% less likely than males to be overweight or obese. Older youth were 73% less likely to be overweight or obese than younger youth. Youth whose parents were obese were more than two times more likely to be overweight or obese than those whose parents were at a desirable weight. Youth in Puerto Rico have higher rates of overweight and obesity and lower compliance to moderate-to-vigorous-intensity physical activity guidelines than rates reported for youth on the mainland. More population-based research is needed to understand the epidemiology of obesity and overweight among island Puerto Rican youth and the contribution of physical activity to the phenomenon.

  6. Sex Education Approaches at Costa Rican Public Universities: An Exploratory Paper

    Full Text Available This research paper aims to show the panorama and scope of the current existing sex education practices carried out by the Costa Rican public universities. It analyzes different initiatives, its theoretical approaches that guide the actions, their purposes and other relevant aspects. The analysis includes secondary information as well as the point of view of students and university staff, as inputs for decision-making aimed at improving the overall education of young people. The findings take part of an exploratory research based on qualitative and quantitative methodologies based on gender and constructionism perspective. The information was gathered via the application of a questionnaire to a specific uneven stratified cluster groups, composed by 766 enrolled undergraduate students since first semester 2011 at Universidad Nacional de Costa Rica. The statistical margin of error was 1.5% and the confidence level of 95%. In addition, two focus groups with students and depth interviews with 16 persons were made. Data were tabulated with CSPRO software and analyzed using R software.  The findings suggest that Costa Rican universities recognize the importance of sex education as an essential part of overall development of students. Most of the initiatives are institutionalized; however, the lack of guidelines or policies on the subject, in most institutions, affects quality, consolidation and expansion of services. The need to strengthen and expand training activities on sexuality was identified as well. The students have a high opinion about the services offered, but few of them use these services, because they are perceived as less accessible and friendly. This paper concludes that it is a priority to maintain and strengthen existing initiatives on sexual education, so that they can effectively satisfy the needs of youth, with timely interventions and quality to enjoy a healthy and safe sexuality free from violence.

    Full Text Available To examine the association between sleep patterns (sleep duration and insomnia symptoms and total and regional bone mineral density (BMD among older Boston Puerto Rican adults.We conducted a cross-sectional study including 750 Puerto Rican adults, aged 47-79 y living in Massachusetts. BMD at 3 hip sites and the lumbar spine were measured using dual-energy X-ray absorptiometry. Sleep duration (≤5 h, 6 h, 7 h, 8 h, or ≥9 h/d and insomnia symptoms (difficulty initiating sleep, difficulty maintaining sleep, early-morning awaking, and non-restorative sleep were assessed by a questionnaire. Multivariable regression was used to examine sex-specific associations between sleep duration, insomnia symptoms and BMD adjusting for standard confounders and covariates.Men who slept ≥9h/d had significantly lower femoral neck BMD, relative to those reporting 8 h/d sleep, after adjusting for age, education level, smoking, physical activity, depressive symptomatology, comorbidity and serum vitamin D concentration. This association was attenuated and lost significance after further adjustment for urinary cortisol and serum inflammation biomarkers. In contrast, the association between sleep duration and BMD was not significant in women. Further, we did not find any significant associations between insomnia symptoms and BMD in men or women.Our study does not support the hypothesis that shorter sleep duration and insomnia symptoms are associated with lower BMD levels in older adults. However, our results should be interpreted with caution. Future studies with larger sample size, objective assessment of sleep pattern, and prospective design are needed before a conclusion regarding sleep and BMD can be reached.

    The objective of this study was to determine the effects of farm management and environmental factors on preharvest spinach contamination with generic Escherichia coli as an indicator of fecal contamination. A repeated cross-sectional study was conducted by visiting spinach farms up to four times per growing season over a period of 2 years (2010 to 2011). Spinach samples (n = 955) were collected from 12 spinach farms in Colorado and Texas as representative states of the Western and Southwestern United States, respectively. During each farm visit, farmers were surveyed about farm-related management and environmental factors using a questionnaire. Associations between the prevalence of generic E. coli in spinach and farm-related factors were assessed by using a multivariable logistic regression model including random effects for farm and farm visit. Overall, 6.6% of spinach samples were positive for generic E. coli. Significant risk factors for spinach contamination with generic E. coli were the proximity (within 10 miles) of a poultry farm, the use of pond water for irrigation, a >66-day period since the planting of spinach, farming on fields previously used for grazing, the production of hay before spinach planting, and the farm location in the Southwestern United States. Contamination with generic E. coli was significantly reduced with an irrigation lapse time of >5 days as well as by several factors related to field workers, including the use of portable toilets, training to use portable toilets, and the use of hand-washing stations. To our knowledge, this is the first report of an association between field workers' personal hygiene and produce contamination with generic E. coli at the preharvest level. Collectively, our findings support that practice of good personal hygiene and other good farm management practices may reduce produce contamination with generic E. coli at the preharvest level.

To our knowledge, this is the first report of an association between field workers' personal hygiene and produce contamination with generic E. coli at the preharvest level. Collectively, our findings support that practice of good personal hygiene and other good farm management practices may reduce produce contamination with generic E. coli at the preharvest level.

  18. Farm Hall: The Play

    Cassidy, David C.

    2013-03-01

    It's July 1945. Germany is in defeat and the atomic bombs are on their way to Japan. Under the direction of Samuel Goudsmit, the Allies are holding some of the top German nuclear scientists-among them Heisenberg, Hahn, and Gerlach-captive in Farm Hall, an English country manor near Cambridge, England. As secret microphones record their conversations, the scientists are unaware of why they are being held or for how long. Thinking themselves far ahead of the Allies, how will they react to the news of the atomic bombs? How will these famous scientists explain to themselves and to the world their failure to achieve even a chain reaction? How will they come to terms with the horror of the Third Reich, their work for such a regime, and their behavior during that period? This one-act play is based upon the transcripts of their conversations as well as the author's historical work on the subject.

  19. Biomass plantations - energy farming

    1981-02-01

    Mounting oil import bills in India are restricting her development programmes by forcing the cutting down of the import of other essential items. But the countries of the tropics have abundant sunlight and vast tracts of arable wastelands. Energy farming is proposed in the shape of energy plantations through forestry or energy cropping through agricultural media, to provide power fuels for transport and the industries and also to provide fuelwoods for the domestic sector. Short rotation cultivation is discussed and results are given of two main species that are being tried, ipil-ipil and Casuarina. Evaluations are made on the use of various crops such as sugar cane, cassava and kenaf as fuel crops together with hydrocarbon plants and aquatic biomass. (Refs. 20)

    the nutrient gap by recycling sewage sludge, and in particular the criteria applied when these technologies are assessed, are analysed. This part of the analysis shows how organic consumers base their assessment of alternative strategies and technologies primarily on concerns about environmental risks...... to phase out their use of conventional manure before 2021. This, however, raises a number of questions about consumers’ acceptance of the alternative technologies that have been proposed to close the nutrient gap. Drawing on qualitative interviews with Danish organic consumers, this paper first discusses...... what, from a consumers perspective, characterizes the technologies consumers associate with organic production. This part of the analysis shows that by and large consumers regard organic technologies as the opposite of conventional farming. Second, consumers’ perceptions of solutions suggested to close...

  1. EPA's proposed Worker Protection Standard and the burdens of the past.

    2015-01-01

    An Environmental Protection Agency (EPA) recommendation for extensive changes to the Agency's 40-year-old Worker Protection Standard is currently stalled in the "proposed rule" stage. The proposal, which was available for public comment until 18 August, would improve safety, training, and hazard communication policies for agricultural pesticides. Exposure to hazards, including high heat, heavy machinery, stoop labor, and pesticides, makes occupational illness uncommonly common among the USA's estimated 2.5 million farm workers. To consider the proposed revisions' likelihood of addressing historical gaps in farmworker protection. The proposal was compared to the existing Worker Protection Standard, and key aspects were analyzed in relation to existing science on farm labor hazards, as well as historic occupational health, labor and immigration policy. US law historically has left farm workers largely unprotected. These exclusions and delays have been tolerated in part thanks to the myth of the independent family farmer, but more significant is the stingy nativism that presumes to benefit from immigrant labor without assuming any responsibility to protect the humans who provide it. In the first half of the 1970s, workers lobbied for robust protections, but rule making was impeded by lack of data and by the disproportionate influence of agricultural employers who sought minimal regulation. In 1974, the EPA passed the first Worker Protection Standard for farm workers. Key aspects of the proposed revision include stronger protections against drift and re-entry exposures, better information provision and training, and increased protections for workers under 16 years. The proposed changes represent an improvement over existing legislation, but do not go far enough. The revision should be strengthened along lines suggested by farm workers themselves, and other labor laws must also be amended to give the men, women, and children who work in the fields of this country full

    With the growing population of older Hispanic adults there is a need for additional research on the mental health care of this patient group. This study explored the impact of anxiety disorders on the health status of 291 older (>/=50 years) Puerto Rican primary care patients (n = 65 with anxiety disorders, n = 226 without anxiety disorders). All analyses controlled for potential confounding variables, including depression diagnosis and physical health burden. Logistic regression indicated that anxiety disorders were associated with higher psychological distress, suicidality, and emergency room service utilization, as well as lower instrumental functioning and perceived health quality. Analysis of covariance indicated that both anxiety disorder status and history of ataque de nervios were related to higher percentages of lifetime somatic symptoms. These data highlight the need for improved recognition and treatment of anxiety disorders in older Puerto Rican adults.

    This paper examines the effect of the cultural category ataques de nervios on responses to the Puerto Rican Diagnostic Interview Schedule (DIS), a Spanish version of structured psychiatric diagnostic interview developed for the NIMH Epidemiologic Catchment Area study. An ataque de nervios scale was created from the Somatization items of the DIS to explore the effect of this culturally meaningful category of distress on responses to a standard psychiatric interview. Analysis of 1,513 cases from a representative sample of the island of Puerto Rico indicated that people reporting ataque symptoms fit the social characteristics described for ataques sufferers in the ethnographic literature. Qualitative data indicated that Puerto Ricans were reporting ataques de nervios in the panic section of the DIS. Questions are raised about the validity of the somatization and panic sections of the DIS in cross-cultural research with Hispanics.

    Full Text Available Even though the population of Puerto Rico includes a large percent of residents with some knowledge of the English language (bilinguals, the vast majority communicates using Spanish, which is their native language. Not surprisingly, the majority of advertisements in Puerto Rican media use the Spanish language. The common sense assumption that Spanish advertising is significantly superior to English advertising when targeting Puerto Rican Hispanics living in Puerto Rico is tested experimentally in this study. The Social Value component of the Theory of Consumption Values was used to generate several Hypotheses that would favor the use of English language. The experiment used magazine-like printed illustrated advertisements to test the hypotheses, all of them dealing with relative effectiveness of Spanish versus English language advertisements. The results show that Spanish advertisements and English advertisements were about the same in terms of their persuasion effectiveness.

  7. Gender differences in use of hearing protection devices among farm operators

    2016-01-01

    Full Text Available Purpose: Although farm operators have frequent exposure to hazardous noise and high rates of noise-induced hearing loss, they have low use of hearing protection devices (HPDs. Women represent about one-third of farm operators, and their numbers are climbing. However, among published studies examining use of HPDs in this worker group, none have examined gender-related differences. The purpose of this study was to examine gender-related differences in use of hearing protection and related predictors among farm operators. Materials and Methods: Data previously collected at farm shows and by telephone were analyzed using t-tests and generalized linear model with zero inflated negative binomial (ZINB distribution. Findings: The difference in rate of hearing protector use between men and women farm operators was not significant. There was no difference between men and women in most hearing protector-related attitudes and beliefs. Conclusion: Although men and women farm operators had similar rates of use of hearing protectors when working in high-noise environments, attitudes about HPD use differed. Specifically, interpersonal role modeling was a predictor of HPD use among women, but not for men. This difference suggests that while farm operators of both genders may benefit from interventions designed to reduce barriers to HPD use (e.g., difficulty communicating with co-workers and hearing warning sounds, farm women have unique needs in relation to cognitive-perceptual factors that predict HPD use. Women farm operators may lack role models for use of HPDs (e.g., in peers and advertising, contributing to their less frequent use of protection.

    Exposure to gun violence and African ancestry have been separately associated with increased risk of asthma in Puerto Rican children. The objective of this study was to examine whether African ancestry and gun violence interact on asthma and total IgE in school-aged Puerto Rican children. This is a case-control study of 747 Puerto Rican children aged 9 to 14 years living in San Juan, Puerto Rico (n = 472), and Hartford, Connecticut (n = 275). Exposure to gun violence was defined as the child's report of hearing gunshots more than once, and the percentage of African ancestry was estimated using genome-wide genotypic data. Asthma was defined as parental report of physician-diagnosed asthma and wheeze in the previous year. Serum total IgE (IU/mL) was measured in study participants. Multivariate logistic and linear regressions were used for the analysis of asthma and total IgE, respectively. In multivariate analyses, there was a significant interaction between exposure to gun violence and African ancestry on asthma (P = .001) and serum total IgE (P = .04). Among children exposed to gun violence, each quartile increase in the percentage of African ancestry was associated with approximately 45% higher odds of asthma (95% CI, 1.15-1.84; P = .002) and an approximately 19% increment in total IgE (95% , 0.60-40.65, P = .04). In contrast, there was no significant association between African ancestry and asthma or total IgE in children not exposed to gun violence. Our results suggest that exposure to gun violence modifies the estimated effect of African ancestry on asthma and atopy in Puerto Rican children.

    Although symptoms during cancer treatments are prevalent and are important clinical outcomes of childhood cancer, the symptom experiences of Puerto Rican children along with the symptom alleviation/care practices that parents provide during cancer treatments have received limited attention. To examine the occurrence/severity of symptoms on the Therapy-Related Symptom Checklist-Children (TRSC-C), reported by mothers of Puerto Rican children undergoing cancer treatments and identifying mothers' symptom alleviation/management strategies. Descriptive study conducted between January and May 2012. Mothers of 65 Puerto Rican children/adolescents undergoing cancer treatments responded to the Spanish versions of the TRSC-C, Symptom Alleviation: Self-Care Methods, and a Demographic and Health form. The children/adolescents' mean age was 9.2 (1-17) years; 62% were boys; 56 had chemotherapy; 9 had chemoradiotherapy. Children diagnoses were 35.4% leukemia, 24.6% solid tumors, 24.6% nervous system tumors, and 15.4% other. On the TRSC-C, the symptoms experienced by 70% or more of the children were: irritability (77%), nausea (75%), and hair loss (72%). On the Symptom Alleviation: Self-Care Methods, the most commonly reported symptom alleviation category was "taking prescribed medicines." Puerto Rican mothers reported the use of alleviation practices to treat their children experiencing symptoms during pediatric cancer treatments. Patients and caregivers need to be educated about treatment-induced side effects, and the life-threatening consequences of underreporting and undermanagement. Symptoms should always be addressed at the time of initiation of primary or adjuvant cancer therapy because pretreatment symptoms may persist or get worse across the trajectory of treatment. A continuous assessment and management of symptoms during the childhood cancer trajectory can optimize clinical care and improve quality of life of patients and families. © 2016 John Wiley & Sons Australia

    Full Text Available Czech agrarian sector has undergone significant changes during last ten years. Since the Czech Republic has entered the European Union in 2004, agrarian sector has had to adapt to conditions of the Common Agricultural Policy (CAP. This policy is taken as a crucial within the EU policies as it includes orientation of food production as well as a broader sense of sustainable development and employment. The paper assesses profit/loss and its efficiency of a sample of farms in the Czech Republic (about 830 farms in 2004 2010. This analysis employed methods of financial analysis both traditional ratios and systems of bankruptcy and value models. Time series is long enough to monitor results after establishing the UE and the CAP principles in the Czech Republic. The paper shows that although since 2004, revenue per employee has been increasing, the value added per worker has been static without any major changes. However, farms on average were profitable with the exception of 2009. It was verified by bankruptcy and value models that an average farm is in a relatively good financial situation (without any problems or debt and sufficiently liquid.

    2010-03-25

    Models of between-farm transmission of pathogens have identified service vehicles and social groups as risk factors mediating the spread of infection. Because of high levels of economic organization in much of the poultry industry, we examined the importance of company affiliation, as distinct from social contacts, in a model of the potential spread of avian influenza among broiler poultry farms in a poultry-dense region in the United States. The contribution of company affiliation to risk of between-farm disease transmission has not been previously studied. We obtained data on the nature and frequency of business and social contacts through a national survey of broiler poultry growers in the United States. Daily rates of contact were estimated using Monte Carlo analysis. Stochastic modeling techniques were used to estimate the exposure risk posed by a single infectious farm to other farms in the region and relative risk of exposure for farms under different scenarios. The mean daily rate of vehicular contact was 0.82 vehicles/day. The magnitude of exposure risk ranged from company affiliation, with farms in the same company group as the index farm facing as much as a 5-fold increase in risk compared to farms contracted with different companies. Employment of part-time workers contributed to significant increases in risk in most scenarios, notably for farms who hired day-laborers. Social visits were significantly less important in determining risk. Biosecurity interventions should be based on information on industry structure and company affiliation, and include part-time workers as potentially unrecognized sources of viral transmission. Modeling efforts to understand pathogen transmission in the context of industrial food animal production should consider company affiliation in addition to geospatial factors and pathogen characteristics. Restriction of social contacts among farmers may be less useful in reducing between-farm transmission.

    Full Text Available Objective: To explore the value of day services at green care farms (GCFs in terms of social participation for people with dementia. Method: Semi-structured interviews were conducted with people with dementia who attended day services at a GCF (GCF group, n = 21, were on a waiting list (WL for day services at a GCF (WL group, n = 12, or attended day services in a regular day care facility (RDCF group, n = 17 and with their family caregivers. Results: People with dementia in the GCF and WL group were primarily males, with an average age of 71 and 76 years, respectively, who almost all had a spousal caregiver. People with dementia in the RDCF group were mostly females with an average age of 85 years, most of whom had a non-spousal caregiver. For both the GCF and RDCF groups, it was indicated that day services made people with dementia feel part of society. The most important domains of social participation addressed by RDCFs were social interactions and recreational activities. GCFs additionally addressed the domains “paid employment” and “volunteer work.” Conclusion: GCFs are valuable in terms of social participation for a particular group of people with dementia. Matching characteristics of adult day services (ADS centers to the preferences and capacities of people with dementia is of importance. Diversity in ADS centers is therefore desirable.

    Exposure to pesticides is a major public health concern, because of the widespread distribution of these compounds and their possible long term effects. Recently, organic farming has been introduced as a consumer and environmental friendly agricultural system, although little is known about the effects on workers' health. The aim of this work was to evaluate genetic damage and immunological alterations in workers of both traditional and organic farming. Eighty-five farmers exposed to several pesticides, thirty-six organic farmers and sixty-one controls took part in the study. Biomarkers of exposure (pyrethroids, organophosphates, carbamates, and thioethers in urine and butyrylcholinesterase activity in plasma), early effect (micronuclei in lymphocytes and reticulocytes, T-cell receptor mutation assay, chromosomal aberrations, comet assay and lymphocytes subpopulations) and susceptibility (genetic polymorphisms related to metabolism - EPHX1, GSTM1, GSTT1 and GSTP1 - and DNA repair-XRCC1 and XRCC2) were evaluated. When compared to controls and organic farmers, pesticide farmers presented a significant increase of micronuclei in lymphocytes (frequency ratio, FR=2.80) and reticulocytes (FR=1.89), chromosomal aberrations (FR=2.19), DNA damage assessed by comet assay (mean ratio, MR=1.71), and a significant decrease in the proportion of B lymphocytes (MR=0.88). Results were not consistent for organic farmers when compared to controls, with a 48% increase of micronuclei in lumphocytes frequency (p=0.016) contrasted by the significant decreases of TCR-Mf (p=0.001) and %T (p=0.001). Our data confirm the increased presence of DNA damage in farmers exposed to pesticides, and show as exposure conditions may influence observed effects. These results must be interpreted with caution due to the small size of the sample and the unbalanced distribution of individuals in the three study groups. Copyright © 2014 Elsevier Ireland Ltd.

    Mental health services increasingly incorporate the vision of recovery. This qualitative study analysed and compared experiences of recovery on prevocational services, in order to assess if users make progress towards recovery, relative to a staged recovery model. Data were collected through semi-structured interviews with participants on care farms (n = 14), work (n = 7) and creative projects (n = 5). The transition from past to current lives was described as a progressive, non-linear process, with different stages guided by different goals. Participants on creative projects lacked clear goals, presented less interest in peers and high need for emotional support. Participants on work projects aimed for occupational rehabilitation, but struggled with the patient culture of the peer community. Participants on care farms aimed for daytime occupations and closer contact with society. They experienced care farms as open, real-life work settings where they could exercise responsibility and connect with people. Participants progressed towards recovery, as care farms, work- and creative projects empowered them to leave behind inactive, isolated or disorganized living. In day centres, users focused on self-reflection and personal development (creative projects) or on occupational performance (work projects), whereas on care farms, users fulfilled worker roles in a real-life, open community environment. Organized as open communities in real-life settings, care farms facilitate the reflection on personal and social responsibility, and therefore have the potential to help users internalize worker identities and improve their motivation to progress towards recovery. Supervisors on care farms are regarded by users as close contacts within the social networks they develop on the service, a position that allows supervisors to actively engage and promote users' progress towards recovery. Elements of the farm environment (such as the "normal life", presence of family

    2014-01-01

    This paper describes the labour management system applied since around 2005 on farms accounting for the bulk of the output of the Kenyan cut flower sector, and provides an analysis of the foundations of this system. Using categories drawn from convention theory, this system is characterized...... in terms of specific approaches to hiring, training and promotion; labour retention; work organization and worker deployment; payment systems and supervision, as well as to collective bargaining. In convention theory terms, the combination of approaches identified in Kenya embodies a mixture of ‘industrial...

    Environmental and agriculture challenges such as severe drought, desertification, sprawling cities and shrinking arable lands in large regions in the world compel us to think about alternative and sustainable farming systems. Ongoing projects to build floating cities in the sea suggest that building specific ships for farming purposes (as farming ships or farming boats) would also be attainable to introduce new farming surfaces and boost food production worldwide to cope with food insecurity issues.

    A very large share of the total raw material potential for biogas production will be found within the agriculture. The raw material potential of manure in Sweden amounts to 4 - 6 TWh. Within the agriculture there is moreover a big potential in the form of residues from plant cultivation and non-food crops (approximately 7 TWh) that can to be used for biogas production. The potential for biogas production from only residues and manure is around 8-10 TWh. An increased biogas production within the agriculture would give significant environmental effects. Among other things manure, that today is leaking methane gas to the atmosphere, can be fermented, and trough this process the methane losses will be reduced. When the produced biogas replaces fossil fuel, an overall environmental effect will be reached, that is highly significant. This manual deals with biogas plants for agriculture and such plants that do not have extensive transports of different raw materials, as manure, wastes etc. One of the starting points for this manual's set-up is a course plan that Biogas Syd made for the courses they give to farmers, advisors and others. The manual illustrates important aspects in planning and construction of biogas plants, from raw material and technology to dimensioning of plant, use of biogas and planning of local gas grids. We also think it is important to illustrate the legislation that encompasses construction work and operation of a biogas plant. Investment costs are also illustrated, but the book does not give any extensive economic calculations, since we believe that such calculations need their own manual in the form of calculation examples, based on various conditions. The final section is called 'Biogas on farm - from idea to reality' where the entire process from analysis and pre-planning to monitoring and control of plant during operation is briefly described

    In this study, I uncovered the dynamics involved in the exchange (or lack) of social support among a group of Puerto Ricans who experienced a natural disaster. I coded and analyzed 12 semistructured qualitative interviews. My analysis of the interviews revealed that a reported high degree of need was not associated with any type of help seeking from the respondents' social support networks. Relevant issues that arose in explaining the lack of social support exchanges were level of comfort in help seeking and cultural issues. My findings point to the importance of culture in shaping patterns of help-seeking behavior in the aftermath of a disaster. Two of the most salient cultural explanations as to why disaster victims were reluctant to ask for help from family and friends were the issues of confianza (trust) and pena (embarrassment). I discuss the results with reference to how they might help in planning and establishing programs to maximize help seeking among Latinos/as in an emergency situation.

    Although opportunities to vaccinate against human papillomavirus (HPV) are available, vaccination rates in Puerto Rico remain low. Communication between parents and adolescents about sexual topics may influence decisions about HPV vaccination uptake, particularly among young women; yet, few studies have addressed this issue. This qualitative study explored Puerto Rican mothers' and daughters' communication on sex-related topics, and HPV, including the HPV vaccine. Thirty participants, including 9 mothers and 21 daughters, participated in seven focus groups. Participants were divided into groups of mothers and daughters, and further stratified by vaccination status. Transcripts were analyzed using a modified grounded theory approach to identify emergent themes. Focus group data revealed four main themes: (1) limited parent-daughter communication about sex-related topics; (2) daughters' discomfort discussing sex-related topics with their parents; (3) parental focus on abstinence; and, (4) limited parent-daughter communication about HPV and the HPV vaccine. Although daughters in this study struggled with feelings of embarrassment, invasion of privacy, encouragement of abstinence, and the fear of parents' reaction to them being sexually active prior to marriage, they also recognized the need to increase the parent-daughter communication about sex-related topics including HPV and the HPV vaccine. Educational efforts should target both daughters and parents to increase communication skills and self-efficacy and to enable them to discuss sexual health in open and nonjudgmental conversations.

    To provide the first empirical analysis of a cultural syndrome in children by examining the prevalence and psychiatric correlates of ataques de nervios in an epidemiological study of the mental health of children in Puerto Rico. Probability samples of caretakers of children 4-17 years old in the community (N = 1,892; response rate: 90%) and in clinical services (N = 761; response rate 72%) were administered structured interviews to assess the presence and correlates of ataques de nervios. Nine percent of children in the community sample and 26% of children in the clinical sample had a reported history of an ataque de nervios. In contrast to the overall community and clinical samples, which had more boys in them, the ataque de nervios groups in both samples had more girls in them. Family history of ataques de nervios was associated with ataques de nervios in children in both samples. Across a wide range of depression, anxiety, and disruptive disorders, children who reported an ataque de nervios were more likely to meet research criteria for psychiatric disorder in both samples. Ataques de nervios are a frequently reported cultural syndrome among children in Puerto Rico. Adolescent girls are more likely to report this experience. Ataques de nervios have a significant relationship with psychiatric disorder and impairment in Puerto Rican children.

    A total of 45 native Costa Rican tree species are threatened or in danger of extinction, but the Convention on International Trade Endangered Species (CITES) includes only eight of these in its Appendices. However, the identification of other species based on their wood anatomy is limited. The present study objective was to describe and to compare wood anatomy and fluorescence activity in some endangered or threatened species of Costa Rica. A total of 45 (22 endangered and 23 threatened with extinction) wood samples of these species, from the xylaria of the Instituto Tecnológico de Costa Rica and the Forest Products Laboratory in Madison, Wisconsin, were examined. Surface fluorescence was positive in eight species, water extract fluorescence was positive in six species and ethanol extract fluorescence was positive in 24 species. Almost all species were diffuse porous except for occasional (Cedrela odorata, C. fissilis, Cordia gerascanthus) or regular (C. salvadorensis and C. tonduzii) semi-ring porosity. A dendritic vessel arrangement was found in Sideroxylon capari, and pores were solitary in Guaiacum sanctum and Vantanea barbourii. Vessel element length was shortest in Guaiacum sanctum and longest in Humiriastrum guianensis, Minquartia guianensis and Vantanea barbourii. Finally, anatomical information and fluorescence activity were utilized to construct an identification key of species, in which fluorescence is a feature used in identification.

    Full Text Available In a region prone to violence and political corruption, Costa Rica has been touted as an ecological paradise, a stable democracy, and an egalitarian society. However, Costa Rican fiction from the late twentieth century contests this idyllic image and presents instead a world of intrigue, violence, and criminality. El año del laberinto (2000 by Tatiana Lobo and Cruz de olvido (1999 by Carlos Cortés are two novels that serve as an excellent introduction to developments in postwar fiction and scholarship from Central America. In my analysis, I first situate the novels in the context of Central American cultural and political developments in recent decades and then consider the linking of narrative, gender, and violence in the novels. My study centers on the authors' use of crime to challenge national myths and to deconstruct narratives that have been instrumental in constructing cherished national identities. Of particular importance is the depiction of gendered bodies and the violence practiced upon them, as well as the politics surrounding bodies and violence in national narratives and in the authors' contemporary stories.

    A dimensional assessment model as a supplement to the diagnosis process could overcome the current pitfalls in classifying psychopathology in ethnic minorities. The aim of the study described herein was to examine a sample of Puerto Rican patients diagnosed with anxiety disorder in order to evaluate the psychometric properties of the specific scales that assess the following 3 domains: clinical symptoms, personality/trait, and affective style. 80 subjects were recruited and interviewed using the Structured Clinical Interview for DSM-IV to identify the presence of anxiety disorders. Following this, various questionnaires assessing each proposed domain were administered to the participants. Reliability and validity of these questionnaires were examined using Cronbach's alpha and exploratory factor analysis. The effect of the individual items of the questionnaires on the overall reliability and validity was assessed using factor scores component matrix. Analyses revealed moderate to high reliability and validity scores within all 3 domains. The sample obtained moderate to high scores on the scales comprising clinical and personality/trait domains. The use of self-report scales in accordance with the proposed dimensional framework may be an effective way to supplement categorical diagnoses within the Hispanic population represented by this sample.

Understanding the factors that control tree growth in successional stands is particularly important for quantifying the carbon sequestration potential and timber yield of secondary tropical forests. Yet, the high species diversity of mixed tropical forests, including many uncommon species, hinders the development of species-specific diameter growth models.Area of study: In these analyses, we grouped 82 species from secondary forests distributed across 93 permanent plots on the island of Puerto Rico.Material and Methods: Species were classified according to regeneration strategy and adult height into six functional groups. This classification allowed us to develop a robust diameter growth model using growth data collected from 1980-1990. We used mixed linear model regression to analyze tree diameter growth as a function of individual tree characteristics, stand structure, functional group and site factors.Main results: The proportion of variance in diameter growth explained by the model was 15.1%, ranging from 7.9 to 21.7%. Diameter at breast height, stem density and functional group were the most important predictors of tree growth in Puerto Rican secondary forest. Site factors such as soil and topography failed to predict diameter growth.Keywords: Caribbean forests; growth model; tropical forest succession; Puerto Rico.

    Intake of added sugars, mainly fructose and sucrose, has been associated with risk factors for cognitive impairment, such as obesity, the metabolic syndrome and type 2 diabetes. The objective of this analysis was to examine whether habitual intakes of total sugars, added sugars, sugar-sweetened beverages or sweetened solid foods are associated with cognitive function. The present study included 737 participants without diabetes, aged 45–75 years, from the Boston Puerto Rican Health Study, 2004–9. Cognitive function was measured with a battery of seven tests: Mini-Mental State Examination (MMSE), word list learning, digit span, clock drawing, figure copying, and Stroop and verbal fluency tests. Usual dietary intake was assessed with a validated FFQ. Greater intakes of total sugars, added sugars and sugar-sweetened beverages, but not of sugar-sweetened solid foods, were significantly associated with lower MMSE score, after adjusting for covariates. Adjusted OR for cognitive impairment (MMSE score sugars and 2·28 (95 % CI 1·26, 4·14) for added sugars, comparing the highest with lowest intake quintiles. Greater intake of total sugars was also significantly associated with lower word list learning score. In conclusion, higher sugar intake appears to be associated with lower cognitive function, but longitudinal studies are needed to clarify the direction of causality. PMID:21736803

    This study designed and validated a questionnaire aimed at examining parental feeding styles to encourage healthy eating habits among Costa Rican adolescents. Adolescents (n=133; mean age 15.4 years), and their parents, participated in the study. The parents completed a parental feeding style questionnaire, and the adolescents completed 3-day food records. Confirmatory factor analyses suggest four distinct parental feeding styles, (a) verbal encouragement of healthy eating behaviors; (b) use of verbal sanctions to indirectly control the intake of healthy food; (c) direct control of access to and intake of food; and (d) use of food to regulate emotions and behavior. There were no correlations between dietary intake and the verbal encouragement of healthy eating behaviors, but there were significant negative correlations between (1) "the use of verbal sanctions to indirectly control the intake of healthy food", and the consumption of fruit and vegetable, of calcium, iron, vitamin B6 and folic acid intake, and (2) between the "direct control of access to and intake of food" and fast food consumption and total carbohydrates intake. The use of food to regulate emotions and behavior was positively correlated with high energy-dense food consumption. Stratification of the data shows significant differences by gender in the correlations between parental feeding style and dietary intake. Understanding parental feeding styles in a Latin American context is a first step in helping researchers develops culturally-appropriate parenting intervention/prevention strategies to encourage healthy eating behaviors during adolescence.

    The diagnosis of Creutzfeldt-Jakob disease (CJD) is often a challenge for most physicians given its extremely low incidence and different clinico-pathological presentations. We report the case of a 56-year old patient native to Puerto Rico suspected of sporadic Creutzfeldt-Jakob disease (sCD). The symptoms at onset were notorious for bilateral cortical blindness followed by rapidly progressive cognitive decline, visual deficit, increased levels of CSF 14-3-3 and tau along with positive brain MRI and EEG, are highly indicative of CJD. The definite diagnosis was confirmed by the National Prion Disease Pathology Surveillance Center (NPDPSC), in Cleveland, Ohio, USA. Lack of genetic mutations in the prion protein (PrP) gene, widespread histopathological changes and the accumulation of scrapie PrP (PrPSc) in the brain confirmed the diagnosis of sCJD. The patient, admitted to our institution in 2011, represents the first detailed report of sCJD in a native Puerto Rican patient living in Puerto Rico.

  5. Bartonellae are Prevalent and Diverse in Costa Rican Bats and Bat Flies.

    Species in the bacterial genus, Bartonella, can cause disease in both humans and animals. Previous reports of Bartonella in bats and ectoparasitic bat flies suggest that bats could serve as mammalian hosts and bat flies as arthropod vectors. We compared the prevalence and genetic similarity of bartonellae in individual Costa Rican bats and their bat flies using molecular and sequencing methods targeting the citrate synthase gene (gltA). Bartonellae were more prevalent in bat flies than in bats, and genetic variants were sometimes, but not always, shared between bats and their bat flies. The detected bartonellae genetic variants were diverse, and some were similar to species known to cause disease in humans and other mammals. The high prevalence and sharing of bartonellae in bat flies and bats support a role for bat flies as a potential vector for Bartonella, while the genetic diversity and similarity to known species suggest that bartonellae could spill over into humans and animals sharing the landscape. © 2015 Blackwell Verlag GmbH.

  6. Forest conservation and the clean development mechanism. Lessons from the Costa Rican protected areas project

    Deforestation is currently the source of about 20% of anthropogenic CO2 emissions. Avoided deforestation has, nonetheless, been ruled out as a Clean Development Mechanism (CDM) category in the Kyoto Protocol's first commitment period, because several methodological issues were considered too difficult to resolve. This paper explores whether CDM issues such as (1) carbon quantification, (2) additionality and baseline setting, (3) leakage risks, (4) non-permanence risks, and (5) sustainable development can be adequately dealt with in large, diversified forest conservation projects. To this aim, it studies the case of the Costa Rican Protected Areas Project (PAP), an Activities Implemented Jointly (AIJ) project which was meant to consolidate the national park system to avoid deforestation, promote the growth of secondary forests and regenerate pastures on an area that, in total, covers 10% of the national territory. The case study examines how the issues mentioned above have been addressed in the project design and in the certification process. It is found that baseline uncertainties are the major problem in this case. Nonetheless, the case suggests the possibility to address CDM issues by specific requirements for project design and very conservative and temporary crediting. Provided that other case studies support this conclusion, eligibility of well-designed forest conservation projects under the CDM in the second commitment period may be worth considering, given the secondary benefits of avoided deforestation

    Wind turbine technology has ventured in recent years from prototypes and first deployments towards large power plant scale projects. With this, also the ownership structure of wind farms changed: from single farmers to cooperatives, and to large multi-national developers specialised in building and running wind power projects. At the same time, the best sites for wind energy were already taken, leading to more remote sites and offshore sites being developed. Both these developments lead to an increased wish for remote monitoring of turbines. Ideally, the turbine would know on its own accord when it would need maintenance, and call the maintenance crew autonomously. The crew then would have all the information they need to have before they go out to the turbine and do the necessary tasks. Having knowledge of the type of fault that has happened would help the maintenance crew to deal with it efficiently. This also could mean to wait until the next scheduled maintenance is due. The potential savings for this alone are considerable, if you think of the plans for offshore wind farms tens of kilometres from the coast, where access would probably be by helicopter. The idea behind this project was to take the existing techniques developed for optimising and enhancing the performance of wind farms, integrate them into one system and implement the system at a number of wind farms. The techniques include remote measuring of the status and production of the wind farm, short-term prediction of the expected wind speeds at and power output from the wind farm, models for wake calculations, remote control of wind farm production and so on.

    A wind farm optimization framework is presented in detail and demonstrated on two test cases: 1) Middelgrunden and 2) Stags Holt/Coldham. A detailed flow model describing the instationary flow within a wind farm is used together with an aeroelastic model to determine production and fatigue loading of wind farm wind turbines. Based on generic load cases, the wind farm production and fatigue evaluations are subsequently condensed in a large pre-calculated database for rapid calculation of lifetime equivalent loads and energy production in the optimization loop. The objective function defining the optimization problem includes elements as energy production, turbine degradation, operation and maintenance costs, electrical grid costs and foundation costs. The objective function is optimized using a dedicated multi fidelity approach with the locations of individual turbines in the wind farm spanning the design space. The results are over all satisfying and are giving some interesting insights on the pros and cons of the design choices. They show in particular that the inclusion of the fatigue loads costs give rise to some additional details in comparison with pure power based optimization. The Middelgrunden test case resulted in an improvement of the financial balance of 2.1 M Euro originating from a very large increase in the energy production value of 9.3 M Euro mainly counterbalanced by increased electrical grid costs. The Stags Holt/Coldham test case resulted in an improvement of the financial balance of 3.1 M Euro. (Author)

  12. HANFORD CHEMICAL VAPORS WORKER CONCERNS and EXPOSURE EVALUATION

    ANDERSON, T.J.

    2006-01-01

    Chemical vapor emissions from underground hazardous waste storage tanks on the Hanford site in eastern Washington State are a potential concern because workers enter the tank farms on a regular basis for waste retrievals, equipment maintenance, and surveillance. Tank farm contractors are in the process of retrieving all remaining waste from aging single-shell tanks, some of which date to World War II, and transferring it to newer double-shell tanks. During the waste retrieval process, tank farm workers are potentially exposed to fugitive chemical vapors that can escape from tank headspaces and other emission points. The tanks are known to hold more than 1,500 different species of chemicals, in addition to radionuclides. Exposure assessments have fully characterized the hazards from chemical vapors in half of the tank farms. Extensive sampling and analysis has been done to characterize the chemical properties of hazardous waste and to evaluate potential health hazards of vapors at the ground surface, where workers perform maintenance and waste transfer activities. Worker concerns. risk communication, and exposure assessment are discussed, including evaluation of the potential hazards of complex mixtures of chemical vapors. Concentrations of vapors above occupational exposure limits-(OEL) were detected only at exhaust stacks and passive breather filter outlets. Beyond five feet from the sources, vapors disperse rapidly. No vapors have been measured above 50% of their OELs more than five feet from the source. Vapor controls are focused on limited hazard zones around sources. Further evaluations of vapors include analysis of routes of exposure and thorough analysis of nuisance odors

    Full Text Available Farm records are mostly manually kept on paper notebooks and folders where similar records are organized in one folder or spread sheet. These records are usually kept for many years therefore they becomes bulky and less organized. Consequently, it becomes difficult to search, update and tedious and time consuming to manage these records. This study was carried-out to overcome these problems associated with manual farm records keeping by developing user-friendly, easily accessible, reliable and secured software. The software was limited records keeping in crop production, livestock production, poultry production, employees, income and expenditure. The system was implemented using Java Server Faces (JSF for designing Graphical User Interface (GUI, Enterprises Java Beans (EJB for logic tier and MySQL database for storing farm records.

  14. Challenges in wind farm optimization

    DEFF Research Database (Denmark)

    Larsen, Gunner Chr.

    To achieve the optimal economic output from a wind farm over its lifetime, an optimal balance between capital costs, operation and maintenance costs, fatigue lifetime consumption of turbine components and power production is to be determined on a rational basis. This has implications both...... for the wind turbine modeling, where aeroelastic models are required, and for the wind farm flow field description, where in-stationary flow field modeling is needed to capture the complicated mixture of atmospheric boundary layer (ABL) flows and upstream emitted meandering wind turbine wakes, which together...... dictates the fatigue loading of the individual wind turbines. Within an optimization context, the basic challenge in describing the in-stationary wind farm flow field is computational speed. The Dynamic Wake Meandering (DWM) model includes the basic features of a CFD Large Eddy Simulation approach...

    Papers presented at the European wind energy conference on the potential of wind farms are presented. The aim of the conference was to bring into focus the problems, experiences and potential of the application of wind power in wind power farms as a contribution to the European and global energy supply. It was considered that the interchange of experience among representatives of science, utilities, industry, environment and energy planning, together with those who represent financial and insurance interests, would create a better understanding of all aspects of wind power for its future successful development. The subjects covered concern surveys of national planning and policies regarding wind energy utilization and national and global development of wind turbine arrays. The performance of some individual wind farms is described. Papers also deal with utility and project planning, wind prediction and certification, wind loads and fatigues, wakes, noise and control.

    2010-01-01

    This article explores how young men in Costa Rica negotiate ideas of manhood under neoliberalism. We draw on interview data involving 23 men, ages 15–35, residing in one Costa Rican city. Comparing men across three different class locations, we find diverse "markers of manhood." Our data suggest an emerging globally dominant masculine ideal among an elite class of men, a declining locally dominant masculine ideal among working-class men, and a cynical, possibly counter-cultural masculine ideal among poor men. We conclude that masculinities are not only fluid, but tied to changing economic circumstances and class structures.

    The role of ethnicity, community structure, and folk concepts of mental illness in facilitating the adaptation of long term psychiatric patients to community living has received little attention. This article examines the cultural concepts of mental illness and the community involvement of 30 Puerto Rican psychiatric patients participating in a New York City treatment program. It is shown that many of the attributes usually associated with chronic mental illness do not apply to this population. It is argued that the folk concept of nervios helps to foster the integration of these patients in a wide range of community networks. The impact of gentrification on these patients' community integration is also discussed.

    Full Text Available Background: Blood sucking mites are important avian ectoparasites which being found on bird species worldwide. Their presence are problematic for the producers either through potential direct effects on weight gain, egg produc­tion, sperm production in roosters or as nuisance pests on worker handle hens and eggs. The aim of this study was pointing out of the status of haematophagus mites.Methods: Eight caged layer and four breeder flocks were visited, monitoring for the presence of chicken mites per­formed by removing and examining debris from poultry house, infested nesting material collected into zip lock plas­tic bags and at least 20 birds were also randomly selected to examine the presence of chicken mites. Mites obtained from each population were mounted in Hoyer,s medium on microscope slides and identified. All eight caged layer and four breeder flocks were inspected, which were infested with chicken blood feeding mites.Results: Massive infestations of Dermanyssus gallinae were common with huge numbers of parasites on birds, cages and the conveyor belts for egg. Only one farm from Mazandaran Province was infested to Ornithonyssus bursa.Conclusion: Dermanyssus gallinae was the most prevalent blood feeder mite in the breeder and caged layer flocks in Iran, while O. bursa was reported as a first record, which found only in a breeder flock in Mazanderan Province. It seems that its presence is limited into the area which affected by both warm and humid environmental conditions.

    Full Text Available The theme of this paper is that succession planning in Australian farming is under-developed.It may be linked to economic and social change which suggests that farmers need to adapt togenerational change but this is being resisted or ignored. The implications of this are the slowdecline of family farming, a poor transfer of skills and knowledge to subsequent generationsof farmers in some parts of the agricultural sector and the potential for an extension of thefinancial services industry to develop a more effective raft of succession planning measuresto mitigate the effects of a traditional approach to succession in agriculture.

    The current generation of UNIX farms at Fermilab are rapidly approaching the end of their useful life. The workstations were purchased during the years 1991-1992 and represented the most cost-effective computing available at that time. Acquisition of new workstations is being made to upgrade the UNIX farms for the purpose of providing large amounts of computing for reconstruction of data being collected at the 1996-1997 fixed-target run, as well as to provide simulation computing for CMS, the Auger project, accelerator calculations and other projects that require massive amounts of CPU. 4 refs., 1 fig., 2 tabs

    Organic farming is increasingly recognized as a prototype for sustainable agriculture. Its guidelines ban the use of artificial fertilizers. However, organic farms may import nutrients from conventional farming through material exchanges. In this study, we aimed at estimating the magnitude of these flows through the quantification of nitrogen, phosphorus and potassium inflows from conventional farming to organic farming. Material inflows and outflows were collected for two cropping years on 63 farms. The farms were located in three French agricultural districts distributed over a gradient of farming activity defined by both the stocking rate and the ratio of the farm area under arable crops. Our results showed that on average, inflows from conventional farming were 23%, 73% and 53% for nitrogen, phosphorus and potassium, respectively. These inflows were strongly determined by the farm production systems. However, for farms similar in terms of production systems, the inflows also depended on the local context, such as the proximity of organic livestock farms: the reliance of organic farming on conventional farming was lower in mixed than in specialized districts. These results highlight the necessity to quantify the contribution of nutrient inflows from conventional farming when assessing organic farming and development scenarios. (letter)

    2010-03-01

    Oral research directed toward the maternal and child dyads is important because mothers are a source of dental caries pathogens and are the health behavior managers and trainers of children. The objectives of this study were: 1) to evaluate the oral health status of the mothers in a sample of 100 children aged 12 to 60 months from a rural community in Puerto Rico, and 2) to compare the children with their mothers' oral health status. A sample of 71 women and 100 of their children, (Mean Age = 28.8 years +/- 9.0, and 36.41 mos +/- 18.2, respectively) were evaluated for DMFT/S and periodontal health or deft/s. A NIDCR calibrated dentist performed all dental evaluations of children and mothers utilizing NIDCR criteria. Descriptive statistics were produced. Mothers' bleeding point prevalence in at least one site was 63%; prevalence of at least one site with pocket depth of 4 to 6 mm was 37 %. Calculus prevalence was, no calculus 25%, supragingival calculus 56.7%, subgingival calculus 2.2%, supra and sub gingival calculus 16.3%. Mean Dental Indices for mothers were DMFS (16.51 -/+ 0.02), DMFT (12.20 +/- 6.76), Caries (2.93 +/- 2.86), Filling (7.07 +/- 8.76), Missing (2.93 +/- 4.53). Children's Mean Dental Indices were defs (4.32 +/- 9.7), deft (2.30 +/- 4.0), decalcifications lesions (1.36 +/-1.9), caries (1.96 +/- 3.2) and surfaces caries (3.81 +/- 8.68), fillings (0.22 +/- 0.83) and extracted teeth (0.043 +/- 0.45). Significant levels of treated and untreated caries and gingival disease were observed in this sample. The importance for primary and secondary prevention, as well as treatment for periodontal and dental disease, in rural Puerto Rican communities is evident from this investigation.

    With stricter laws regulating the capture and possession of wild animals in Costa Rica, local wildlife-rescue centers have been overwhelmed by an influx of confiscated or relinquished illegal pets, specifically of psittacine species. As part of a nationwide health-assessment program targeting these centers, 122 birds representing five psittacine species ( Ara macao, Amazona autumnalis, Amazona auropalliata, Amazona farinosa, Aratinga finschi) and one hybrid macaw ( Ara macao × Ara ambiguus) were examined and tested between January 2011 and October 2012. Physical examination, hematology, and serum biochemical analyses were performed. Blood and feathers were tested for psittacine beak and feather disease virus (PBFDV) and avian polyomavirus (APV) via PCR. A DNA-based prevalence and sequence analysis characterized the strains of PBFDV and APV isolated. Physical abnormalities observed in 36% of the 122 birds examined were limited to thin body condition and poor feather quality. None of the feather abnormalities were characteristic of disease caused by either PBFDV or APV. Results of hematological and biochemical analyses were within normal limits except for five birds with leukocytosis and heterophilia, three birds with uric acid values above 16 mg/dl, and two additional birds with AST values above 400 IU/L. No hemoparasites were detected during blood smear examination. Overall prevalences of 9.8% (12/122) for PBFDV and 3.3% (4/122) for APV were documented, with only one bird testing positive for both PBFDV and APV. Birds from two of the eight centers were negative for both viruses. Findings from this study constitute the beginning of a standardized surveillance program for Costa Rican rescue centers, targeting the management of avian species enrolled in propagation and reintroduction programs and expanding of the spectrum of pathogen surveillance and husbandry recommendations in prerelease centers.

    Objective To document the natural course of sensation seeking from childhood to adolescence, characterize distinct sensation-seeking trajectories, and examine how these trajectories vary according to selected predictors. Method Data were obtained from the Boricua Youth Study, a longitudinal study of 2,491 children and adolescents of Puerto Rican background (three assessments from 2000 to 2004). First, age-specific sensation-seeking levels were characterized. Then, age-adjusted residuals were analyzed using growth mixture models (GMM). Results On average, sensation seeking was stable in childhood (ages 5–10) and increased during adolescence (ages 11–17). Mean scores of sensation seeking were higher in the South Bronx vs. Puerto Rico and among males vs. females. Four classes of sensation-seeking trajectories were observed: most study participants had age-expected sensation-seeking trajectories following the average for their age (“normative,” 43.8%); others (37.2%) remained consistently lower than the expected average for their age (“low” sensation seeking); some (12.0%) had an “accelerated” sensation-seeking trajectory, increasing at a faster rate than expected, while a minority (7.0%) had a decreasing sensation-seeking trajectory that started high but decreased, reaching scores slightly higher than the age-average sensation-seeking scores (“stabilizers”). Site (South Bronx vs. Puerto Rico) and gender were predictors of membership in a specific class of sensation-seeking trajectory. Conclusion It is important to take a developmental approach when examining sensation seeking and to consider gender and the social environment when trying to understand how sensation seeking evolves during childhood and adolescence.

    Island Puerto Rican (PR) youth experience disproportionately high asthma and obesity rates compared with other racial/ethnic groups on the U.S. mainland. Previous research has demonstrated associations of chronic disease with psychiatric disorders. We examined the relationship among anxiety/depressive disorders, asthma, and obesity in an epidemiologic community sample of youth. The sample (n = 656) was derived from the second wave of an island-wide probabilistic representative household sample of PR youth stratified and based on whether or not they had a diagnosis of asthma and/or depressive/anxiety disorder. For this study, we used the subpopulation ages 10-19 years. Asthma and obesity were significantly related to higher odds of depressive/anxiety disorders in youth. Obesity moderated the relationship between asthma attacks and depressive/anxiety disorders. The relationship between asthma attack and higher odds for depressive/anxiety disorders was only present in the non-obese group. Among the obese, females show a significant increase from 11% to 36% in the prevalence of anxiety/depressive disorders. Asthma and obesity were highly prevalent and a significant association was found between asthma attack and depressive/anxiety disorders. The effects of asthma and obesity were not additive; the prevalence for psychiatric disorder for those having both conditions did not increase above the prevalence associated having only one of the conditions. Future studies should consider including longitudinal designs and examine the extent to which important variables not included in this study, such as body image dissatisfaction (particularly among females), teasing, and discrimination may moderate the relationship among obesity and depressive and anxiety disorders in youth.

    The Department of Energy (DOE) is in the process of defining the magnitude and diversity of Decontamination and Decommissioning (D ampersand D) obligations at its numerous sites. The DOE believes that existing technologies are inadequate to solve many challenging problems such as how to decontaminate structures and equipment cost effectively, what to do with materials and wastes generated, and how to adequately protect workers and the environment. Preliminary estimates show a tremendous need for effective use of resources over a relatively long period (over 30 years). Several technologies are being investigated which can potentially reduce D ampersand D costs while providing appropriate protection to DOE workers. The DOE recognizes that traditional methods used by the EPA in hazardous waste site clean up activities are insufficient to provide the needed protection and worker productivity demanded by DOE D ampersand D programs. As a consequence, new clothing and equipment which can adequately protect workers while providing increases in worker productivity are being sought for implementation at DOE sites. This project will result in the development of an Advanced Worker Protection System (AWPS). The AWPS will be built around a life support backpack that uses liquid air to provide cooling as well as breathing gas to the worker. The backpack will be combined with advanced protective garments, advanced liquid cooling garment, respirator, communications, and support equipment to provide improved worker protection, simplified system maintenance, and dramatically improve worker productivity through longer duration work cycles. Phase I of the project has resulted in a full scale prototype Advanced Worker Protection Ensemble (AWPE, everything the worker will wear), with sub-scale support equipment, suitable for integrated testing and preliminary evaluation. Phase II will culminate in a full scale, certified, pre-production AWPS and a site demonstration

    Pork production in China is rapidly increasing and swine production operations are expanding in size and number. However, the biosecurity measures necessary to prevent swine disease transmission, particularly influenza. viruses (IAV) that can be zoonotic, are often inadequate. Despite this risk, few studies have attempted to comprehensively study IAV ecology in swine production settings. Here, we present environmental and animal sampling data collected in the first year of an ongoing five-year prospective epidemiological study to assess IAV ecology as it relates to swine workers, their pigs, and the farm environment. From March 2015 to February 2016, we collected 396 each of environmental swab, water, bioaerosol, and fecal/slurry samples, as well as 3300 pig oral secretion samples from six farms in China. The specimens were tested with molecular assays for IAV. Of these, 46 (11.6%) environmental swab, 235 (7.1%) pig oral secretion, 23 (5.8%) water, 20 (5.1%) bioaerosol, and 19 (4.8%) fecal/slurry specimens were positive for influenza. by qRT-PCR. Risk factors for IAV detection among collected samples were identified using bivariate logistic regression. Overall, these first year data suggest that IAV is quite ubiquitous in the swine production environment and demonstrate an association between the different types of environmental sampling used. Given the mounting evidence that some of these viruses freely move between pigs and swine workers, and that mixing of these viruses can yield progeny viruses with pandemic potential, it seems imperative that routine surveillance for novel IAVs be conducted in commercial swine farms.

  3. Dispersive stresses in wind farms

    Segalini, Antonio; Braunbehrens, Robert; Hyvarinen, Ann

    2017-11-01

    One of the most famous models of wind farms is provided by the assumption that the farm can be approximated as a horizontally-homogeneous forest canopy with vertically-varying force intensity. By means of this approximation, the flow-motion equations become drastically simpler, as many of the three-dimensional effects are gone. However, the application of the horizontal average operator to the RANS equations leads to the appearance of new transport terms (called dispersive stresses) originating from the horizontal (small-scale) variation of the mean velocity field. Since these terms are related to the individual turbine signature, they are expected to vanish outside the roughness sublayer, providing a definition for the latter. In the present work, an assessment of the dispersive stresses is performed by means of a wake-model approach and through the linearised code ORFEUS developed at KTH. Both approaches are very fast and enable the characterization of a large number of wind-farm layouts. The dispersive stress tensor and its effect on the turbulence closure models are investigated, providing guidelines for those simulations where it is impossible to resolve the farm at a turbine scale due to grid requirements (as, for instance, mesoscale simulations).

    Wind power is employed worldwide as an alternative source of energy. At the same time, however, the health effects of wind turbines have become a matter of discussion. The purpose of this study is a critical review of available reports providing arguments both for and against the construction of wind farms. The authors also attempt to propose recommendations in accordance with the Evidence-Based Medicine (EBM) guidelines. In the case of exposure to wind farms, a randomized controlled trial (RCT) is impossible. To obtain the highest-level recommendations, analysis of case-control studies or cohort studies with control groups should be performed. Preferably, it should include geostatistical analysis conducted with the use of variograms and the kriging technique. Combinations of key words were entered into the Thomson Reuters Web of Knowledge (SM) and the Internet search engine Google. SHORT DESCRIPTION OF STATE OF THE ART: The nuisance caused by wind turbines is stereotypically linked with the noise that they produce. Nevertheless, the visual aspect of wind farms, opinions about them, and sensitivity to sound seem to be of the greater importance. To date, the direct correlations between the vicinity of modern wind farms, the noise that wind turbines make, and possible consequences to health have not been described in peer reviewed articles. Health effects are more probably associated with some environmental factors leading to annoyance or frustration. All types of studies share the same conclusion: wind turbines can provoke annoyance. As with any project involving changes in the local environment, a certain level of irritation among the population can be expected. There are elected officials and government representatives who should decide what level of social annoyance is acceptable, and whether wind power advantages outweigh its potential drawbacks. The influence of wind turbines on human emotional and physical health is a relatively new field of research. Further

    Viral diseases have been responsible for significant losses in crop yield of garlic in the world. Costa Rican material Garlic has been analyzed to determine the incidence of : onion yellow dwarf virus (OYDV), the leek yellow stripe virus (LYSV), shallot latent virus (SLV) and garlic common latent virus (GLCV). The DAS-ELISA technique has been used for status native plant material. Bulbs field apparently normal (N), normal with yellow tunic (TA) and deformed (D) and normal field sheets (N), symptomatic (S) and possible presence of viral vectors (VT) were used. Vitroplants product have analyzed the introduction of apices of 1,0 and 0,5 cm in length teeth from normal (N) and yellow tunic (TA). The 33% of the bulbs GCLV field were analyzed for positive (TA), whereas OYDV was detected 100% appearance regardless. 100% of the plantlets have presented without infection of GCLV, the OYDV only those introduced in apices of 1,0 cm from bulbs with yellow robes have shown without effect. GCLV is determined for 100% of the samples for both batches OYDV bulb formation in vitro and in only 50%. In the Costa Rican garlic has concluded that are present the viruses of GCLV and OYDV, with a high incidence on local material and differential infection according to the organ analyzed. Various methodologies combined are recommended together with the apexes vitro cultivation, for more effective viral clearance and thus increase the value and boost the local seed crop. (author) [es

    2013-01-01

    Assistive technology (AT) is important for individuals with disabilities' independence and participation in daily life, and there is a lack of valid AT outcome tools for the Puerto Rican population. This pilot study examined the content validity of a new adaptation of the Psychosocial Impact of Assistive Device Scale (PIADS): the Puerto Rican-Spanish PIADS (PR-PIADS). Following standard procedures, the cultural adaptation methodology included a bilingual multidisciplinary committee review of the original (English language) and Spanish versions of the PIADS and pilot testing of the preliminary version of the PR-PIADS with 20 AT users. The committee recommended a total of 58 semantic and conceptual modifications of the Spanish PIADS. Pilot data analysis resulted in 4 additional semantic and conceptual modifications of items that did not reach the minimum content validity ratio of 0.42 for a panel composed by 20 members: competence (0), efficiency (-0.6), performance (-0.95), and eagerness to take chances (-0.6). This pilot study demonstrated evidence of initial content validity of the PR-PIADS. Future research is required before using this tool with greater confidence to address the construct validity and reliability that are also critical to a successful cultural adaptation.

  4. Puerto Rican understandings of child disability: methods for the cultural validation of standardized measures of child health.

    Science.gov (United States)

    Gannotti, Mary E; Handwerker, W Penn

    2002-12-01

    Validating the cultural context of health is important for obtaining accurate and useful information from standardized measures of child health adapted for cross-cultural applications. This paper describes the application of ethnographic triangulation for cultural validation of a measure of childhood disability, the Pediatric Evaluation of Disability Inventory (PEDI) for use with children living in Puerto Rico. The key concepts include macro-level forces such as geography, demography, and economics, specific activities children performed and their key social interactions, beliefs, attitudes, emotions, and patterns of behavior surrounding independence in children and childhood disability, as well as the definition of childhood disability. Methods utilize principal components analysis to establish the validity of cultural concepts and multiple regression analysis to identify intracultural variation. Findings suggest culturally specific modifications to the PEDI, provide contextual information for informed interpretation of test scores, and point to the need to re-standardize normative values for use with Puerto Rican children. Without this type of information, Puerto Rican children may appear more disabled than expected for their level of impairment or not to be making improvements in functional status. The methods also allow for cultural boundaries to be quantitatively established, rather than presupposed. Copyright 2002 Elsevier Science Ltd.

    To establish databases of allele frequencies in a Costa Rican Central Valley population sample. Peripheral blood samples from more than 40 individual were used to isolate DNA and analyze each sample with 10 dinucleotide repeat genetic markers and with 2 mini satellite repeats, using the polymerase chain reaction. Alleles were identified by comparison with DNA from CEPH family members. Genotypes were determined by labelling one of the two Pcr primers with 32P before amplification, electrophoresis in sequencing gels and autoradiography. Analysis of this data set indicates that these samples is in Hardy-Weinberg equilibrium and shows no evidence of linkage disequilibrium between markers. These data are compared with results from other human populations analyzed with the same markers, finding similarities in allele frequencies among them. Notably, the Costa Rican sample presents the lowest heterozygosity value, with 4 of the 10 dinucleotide markers tested, followed by a Cerdenian sample. In contrast, the two African samples presented the highest heterozygosity indexes with a larger number of alleles. (L. Jimenez) [es

    Little is known about the distinct perceptions towards rice and beans that may shape the consumption of these main staple foods among Costa Ricans. We aimed to identify barriers and motivators that could change the current staple into a healthier one, and assess the sensory perceptions of these foods in this population. Focus group discussions and sensory tastings of 8 traditional white or brown rice and beans preparations were conducted in 98 Costa Ricans, aged 40-65 years. Traditional habits and family support emerged as the two main drivers for current consumption. Consuming similar amounts of rice and beans, as well as unfamiliarity with brown rice, are habits engrained in the Costa Rican culture, and are reinforced in the family and community environment. Suggested strategies for consuming more brown rice and more beans included introducing them during childhood, disseminating information of their health benefits that take into account the importance of tradition, lowering the cost, increasing availability, engaging women as agents of change and for brown rice masking the perceived unpleasant sensory characteristics by incorporating them into mixed dishes. Plain brown rice received the lowest mean hedonic liking scores. The preparations rated highest for pleasant were the beans: rice 1:1 ratio regardless of the type of rice. This study identified novel strategies to motivate Costa Rican adults to adapt their food choices into healthier ones within their cultural and sensory acceptability. Copyright © 2014 Elsevier Ltd.

  15. Rural Non Farm Employment in Assam: Trends and Issues

    Directory of Open Access Journals (Sweden)

    Chandrama Goswami

    2014-06-01

    Full Text Available This study explores the rural labour market in Assam. The Work Participation Rates (WPR for males has increased during the period 1993-94 to 2009-10, whereas the same for females has been fluctuating around a lower level of 15 to 20 per cent. Thus, unemployment rates for females have been higher than males. A sector-wise distribution of workers shows that the proportion of males employed in the farm sector has been declining in favour of the Non-Farm Sector (NFS, while the females are more concentrated in the farm sector. Thus, females stand in a more disadvantageous situation in the rural labour market as indicated by their low WPR, higher unemployment rates and low level of diversification into NFS. However, gender equality is necessary for growth. This is more so with regard to education and employment. India has introduced the concept of inclusive growth in the Eleventh Five Year Plan. Inclusive growth ensures opportunities for all sections of the population, with a special emphasis on the poor, particularly women and young people, who are most likely to be marginalised. A rapidly growing population in India has not only increased the size of the rural labour force but has also led to fragmentation of land holdings. Thus, this sector alone cannot create additional employment opportunities, even in high growth agriculture states of India. This has led to the growth of a vibrant non-farm sector. The study comes up with the suggestion that the NFS, with its greater potential of employment generation, can not only solve the unemployment problem, but can also lead to the increased access of women to resources and employment opportunities.

    The aim of the study was to evaluate the microbiological and chemical contamination in settled dust at poultry farms. The scope of research included evaluating the contributions of the various granulometric fractions in settled dust samples, assessing microbial contamination using culture methods, concentrations of secondary metabolites in dust and their cytotoxicity against hepatocyte chicken cells by means of MTT (3-(4,5-dimethylthiazolyl-2)-2,5-diphenyltetrazolium bromide) tests. In addition, we also evaluated the concentration of selected volatile odorous compounds (VOCs) using gas chromatographic and spectrophotometric methods and airborne dust concentration in the air with DustTrak™ DRX Aerosol Monitor. Studies were carried out on chicken broilers and laying hens at 13 poultry farms, with numbers of birds ranging from 8000 to 42,000. The airborne total dust concentration at poultry farms averaged 1.44 mg/m³ with a high percentage of the PM10 fraction (particulate matter with a diameter less than 10 μm). Microorganism concentrations in the settled dust were: 3.2 × 10⁸ cfu/g for bacteria and 1.2 × 10⁶ cfu/g for fungi. Potential pathogens (Enterococcus spp., Escherichia coli, Salmonella spp., Aspergillus fumigatus, Paecilomyces variotii) were also found. Secondary metabolites included aurofusarin, deoxynivalenol, 15-hydroxyculmorin zearalenone, zearalenone-sulfate, infectopyron, and neochinulin A. However, the dust samples showed weak cytotoxicity towards chicken hepatocyte cells, which ranged between 9.2% and 29.7%. Among volatile odorous compounds ammonia, acrolein, methyloamine, acetic acid, acetoaldehyde and formaldehyde were detected in the air. In conclusion, settled dust can be a carrier of microorganisms, odours and secondary metabolites in poultry farms, which can be harmful to workers' health.

  17. Farm Typology in the Berambadi Watershed (India: Farming Systems Are Determined by Farm Size and Access to Groundwater

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Farmers’ production decisions and agricultural practices directly and indirectly influence the quantity and quality of natural resources, some being depleted common resources such as groundwater. Representing farming systems while accounting for their flexibility is needed to evaluate targeted, regional water management policies. Farmers’ decisions regarding investing in irrigation and adopting cropping systems are inherently dynamic and must adapt to changes in climate and agronomic, economic and social, and institutional, conditions. To represent this diversity, we developed a typology of Indian farmers from a survey of 684 farms in Berambadi, an agricultural watershed in southern India (state of Karnataka. The survey provided information on farm structure, the cropping system and farm practices, water management for irrigation, and economic performances of the farm. Descriptive statistics and multivariate analysis (Multiple Correspondence Analysis and Agglomerative Hierarchical Clustering were used to analyze relationships between observed factors and establish the farm typology. We identified three main types of farms: (1 large diversified and productivist farms; (2 small and marginal rainfed farms, and (3 small irrigated marketing farms. This typology represents the heterogeneity of farms in the Berambadi watershed.

  20. Stability analysis of offshore wind farm and marine current farm

    Science.gov (United States)

    Shawon, Mohammad Hasanuzzaman

    Renewable energy has been playing an important role to meet power demand and 'Green Energy' market is getting bigger platform all over the world in the last few years. Due to massive increase in the prices of fossil fuels along with global warming issues, energy harvesting from renewable energy sources has received considerable interest, nowadays, where extensive researches are going on to ensure optimum use of renewable sources. In order to meet the increasing demand of electricity and power, integration of renewable energy is getting highest priorities around the world. Wind is one of the most top growing renewable energy resources and wind power market penetration is expected to reach 3.35 percent by 2013 from its present market of about 240 GW. A wind energy system is the most environmental friendly, cost effective and safe among all renewable energy resources available. Another promising form of renewable energy is ocean energy which covers 70 % of the earth. Ocean energy can be tapped from waves, tides and thermal elements. Offshore Wind farm (OWF) has already become very popular for large scale wind power integration with the onshore grid. Recently, marine current farm (MCF) is also showing good potential to become mainstream energy sources and already successfully commissioned in United Kingdom. However, squirrel cage induction generator (SCIG) has the stability problem similar to synchronous generator especially during fault location to restore the electromagnetic torque. Series dynamic braking resistor (SDBR) has been known as a useful mean to stabilize fixed speed wind generator system. On the other hand, doubly fed induction generator (DFIG) has the capability of coupling the control of active and reactive power and to provide necessary reactive power demand during grid fault conditions. Series dynamic braking resistor (SDBR) can also be employed with DFIG to limit the rotor over current. An integration of wind and tidal energy represents a new

High performance dairy goats demand excellent feedstuffs, a sound environment and top management. It was not clear how organic farming can fulfil these demands. The restrictive factors influencing the productivity of the animals in organic farming are as follows: limited concentrate feeding (

    Full Text Available In the last decade livestock-associated methicillin-resistant S. aureus (LA-MRSA has become a public health concern in many parts of the world. Sequence type 398 (ST398 has been the most commonly reported type of LA-MRSA. While many studies have focused on long-term exposure experienced by swine workers, this study focuses on short-term exposures experienced by veterinary students conducting diagnostic investigations. The objectives were to assess the rate of MRSA acquisition and longevity of carriage in students exposed to pork farms and characterize the recovered MRSA isolates. Student nasal swabs were collected immediately before and after farm visits. Pig nasal swabs and environmental sponge samples were also collected. MRSA isolates were identified biochemically and molecularly including spa typing and antimicrobial susceptibility testing. Thirty (30 veterinary students were enrolled and 40 pork farms were visited. MRSA was detected in 30% of the pork farms and in 22% of the students following an exposure to a MRSA-positive pork farm. All students found to be MRSA-positive initially following farm visit were negative for MRSA within 24 hours post visit. Most common spa types recovered were t002 (79%, t034 (16% and t548 (4%. Spa types found in pork farms closely matched those recovered from students with few exceptions. Resistance levels to antimicrobials varied, but resistance was most commonly seen for spectinomycin, tetracyclines and neomycin. Non-ST398 MRSA isolates were more likely to be resistant to florfenicol and neomycin as well as more likely to be multidrug resistant compared to ST398 MRSA isolates. These findings indicate that MRSA can be recovered from persons visiting contaminated farms. However, the duration of carriage was very brief and most likely represents contamination of nasal passages rather than biological colonization. The most common spa types found in this study were associated with ST5 and expands the range of

    Full Text Available We evaluated the factors influencing the adoption of rice-fish farming in the Tavalesh region near the Caspian Sea in northern Iran. We conducted a survey with open-ended questions. Data were collected from 184 respondents (61 adopters and 123 non-adopters randomly sampled from selected villages and analyzed using logistic regression and multi-response analysis. Family size, number of contacts with an extension agent, participation in extension-education activities, membership in social institutions and the presence of farm workers were the most important socio-economic factors for the adoption of rice-fish farming system. In addition, economic problems were the most common issue reported by adopters. Other issues such as lack of access to appropriate fish food, losses of fish, lack of access to high quality fish fingerlings and dehydration and poor water quality were also important to a number of farmers.

    In a cross-sectional serosurvey, eastern North Carolina swine workers (n = 165) were compared with non-swine workers (127) for the presence of antibodies to hepatitis E virus as measured by a quantitative immunoglobulin enzyme-linked immunosorbent assay. Using a cutoff of 20 Walter Reed U/ml, swine-exposed subjects had a 4.5-fold higher antibody prevalence (10.9%) than unexposed subjects (2.4%). No evidence of past clinical hepatitis E or unexplained jaundice could be elicited. Swine (84) and mice (61), from farm sites in the same region as exposed subjects, were also tested. Antibody prevalence in swine (overall = 34.5%) varied widely (10.0-91.7%) according to site, but no antibody was detected in mice. Our data contribute to the accumulating evidence that hepatitis E may be a zoonosis and specifically to the concept of it as an occupational infection of livestock workers.

    Until recently Oman was a country of emigration, but by 1980 an estimated 200,000 foreign workers were in the country due to the petroleum boom. Almost 1/3 of the estimated 300,000 Indian workers in the Gulf states were in Oman, a country whose colonial heritage was closely tied to that of India and many of whose inhabitants still speak Urdu. The number of work permits granted to Indians working in the private sector in Oman increased from 47,928 in 1976 to 80,787 in 1980. An estimated 110,000 Indians were working in Oman in 1982, the great majority in the construction and public works sector. A few hundred Indian women were employed by the government of Oman, as domestics, or in other capacities. No accurate data is available on the qualifications of Indian workers in Oman, but a 1979 survey suggested a relatively low illiteracy rate among them. 60-75% of Indians in Oman are from the state of Kerala, followed by workers from the Punjab and the southern states of Tamil Nadu and Andhra Pradesh and Bombay. Indian workers are recruited by specialized agencies or by friends or relatives already employed in Oman. Employers in Oman prefer to recruit through agencies because the preselection process minimizes hiring of workers unqualified for their posts. Officially, expenses of transportation, visas, and other needs are shared by the worker and the employer, but the demand for jobs is so strong that the workers are obliged to pay commissions which amount to considerable sums for stable and well paying jobs. Wages in Oman are however 2 to 5 times the level in India. Numerous abuses have been reported in recruitment practices and in failure of employers in Oman to pay the promised wages, but Indian workers have little recourse. At the same level of qualifications, Indians are paid less then non-Omani Arabs, who in turn receive less than Oman nationals. Indians who remain in Oman long enough nevertheless are able to support families at home and to accumulate considerable

    Full Text Available Hereditary motor and sensory neuropathy (HMSN or Charcot-Marie-Tooth disease (CMT is the most common hereditary illness of the peripheral nervous system. The genetics and the physiopathological aspects of the disease clarified until know, are here summarized. More than twenty genes and ten additional loci have been related with HMSN. These findings contribute to understand the metabolism of peripheral nerves and give the basis for molecular diagnostics and future therapy. Several Costa Rican families with CMT have been identified, specially with axonal forms. Two families present mutations in the myelin protein zero gene (MPZ. In addition, linkage have been found between the disease and locus 19q13.3 in an extended family, and a mutation segregating with the disease is present in a candidate gene of the critical interval. Costa Rica has several advantages for genetical studies, that can contribute importantly in the generation of knowledge in the neurogenetical field. Rev. Biol. Trop. 52(3: 475-483.

    There is an increasing search for antibiofilm agents that either have specific activity against biofilms or may act in synergy with antimicrobials. Our objective is to examine the the antibiofilm properties of stingless bee honeys. Meliponini honeys from Costa Rica were examined along with Medihoney as a reference. All honeys were submitted to a screening composed of minimum inhibitory concentration, inhibition of biofilm formation and biofilm destruction microplate-based assays against a Staphylococcus aureus biofilm forming strain. Dialysis led to the isolation of an antibiofilm fraction in Tetragonisca angustula honeys. The honey antibiofilm fraction was evaluated for protease activity and for any synergistic effect with antibiotics on a Staphylococcus aureus biofilm. The active fraction was then separated through activity guided isolation techniques involving SDS-PAGEs, anion exchange and size exclusion fast protein liquid chromatographies. The fractions obtained and the isolated antibiofilm constituents were tested for amylase and DNase activity. A total of 57 Meliponini honeys from Costa Rica were studied in this research. The honeys studied belonged to the Tetragonisca angustula (n=36) and Melipona beecheii (n=21) species. Costa Rican Tetragonisca angustula honeys can inhibit the planktonic growth, biofilm formation, and are capable of destroying a Staphylococcus aureus biofilm. The antibiofilm effect was observed in the protein fraction of Tetragonisca angustula honeys. The biofilm destruction proteins allowed ampicillin and vancomycin to recover their antimicrobial activity over a Staphylococcus aureus biofilm. The antibiofilm proteins are of bee origin, and their activity was not due to serine, cysteine or metalloproteases. There were 2 proteins causing the antibiofilm action; these were named the Tetragonisca angustula biofilm destruction factors (TABDFs). TABDF-1 is a monomeric protein of approximately 50kDa that is responsible of the amylase activity

    Although genetic influences on bipolar I disorder are well established, localization of genes that predispose to the illness has been difficult. Some genes predisposing to bipolar I disorder may be transmitted without expression of the categorical clinical phenotype. One strategy to overcome this obstacle is the use of quantitative endophenotypes, as has been done for other medical disorders. We analyzed 30 bipolar I extended families (300 subjects, average family size 10.34 members, range: 2-31) and 20 unrelated healthy controls from a Costa Rican sample. Heritability and genetic correlation of the state and trait scale from the Anxiety State and Trait Inventory was computed by using the general linear model (SOLAR package software). We also assessed variation of both scores among groups (patients, relatives and controls) and tested independence of affection status. Heritability for state is 0.45 (SE=0.11, p=0.0000001) and for trait is 0.89 (SE=0.06, p=6.22e-29). Genetic correlation for state and trait is 0.29, (SE=0.12, p=0.038-3.19e-8). Bipolar I patients showed the highest trait score (F=12.17 [5,24], p=0.002), (bipolar I patients>relatives with other pathologies, >healthy relatives>unrelated healthy controls) with normal distribution in healthy individuals and no difference regarding depression and mania current status, (F=0.230, df=1, p=0.632 and F=1.401, df=1, p=0.238, respectively), contrary to the state score. Confounding factors such as comorbid disorders could affect the interaction of subclinical anxiety with mania. Due to our limited budget we were not able to re-evaluate the subjects and conduct a test retest to assess the STAI reliability and mood state independence of anxiety traits over different times. Further research is needed to evaluate if anxiety traits are specially related to bipolar I disorder in comparison with other traits such as anger, attention or response inhibition deficit, pathological impulsivity or low self-directedness.

    Long-term hydrological data are key to understanding catchment behaviour and for decision making within water management and planning. Given the lack of observed data in many regions worldwide, hydrological models are an alternative for reproducing historical streamflow series. Additional types of information - to locally observed discharge - can be used to constrain model parameter uncertainty for ungauged catchments. Climate variability exerts a strong influence on streamflow variability on long and short time scales, in particular in the Central-American region. We therefore explored the use of climate variability knowledge to constrain the simulated discharge uncertainty of a conceptual hydrological model applied to a Costa Rican catchment, assumed to be ungauged. To reduce model uncertainty we first rejected parameter relationships that disagreed with our understanding of the system. We then assessed how well climate-based constraints applied at long-term, inter-annual and intra-annual time scales could constrain model uncertainty. Finally, we compared the climate-based constraints to a constraint on low-flow statistics based on information obtained from global maps. We evaluated our method in terms of the ability of the model to reproduce the observed hydrograph and the active catchment processes in terms of two efficiency measures, a statistical consistency measure, a spread measure and 17 hydrological signatures. We found that climate variability knowledge was useful for reducing model uncertainty, in particular, unrealistic representation of deep groundwater processes. The constraints based on global maps of low-flow statistics provided more constraining information than those based on climate variability, but the latter rejected slow rainfall-runoff representations that the low flow statistics did not reject. The use of such knowledge, together with information on low-flow statistics and constraints on parameter relationships showed to be useful to

    Full Text Available Abstract Background A long term research goal of venomics, of applied importance for improving current antivenom therapy, but also for drug discovery, is to understand the pharmacological potential of venoms. Individually or combined, proteomic and transcriptomic studies have demonstrated their feasibility to explore in depth the molecular diversity of venoms. In the absence of genome sequence, transcriptomes represent also valuable searchable databases for proteomic projects. Results The venom gland transcriptomes of 8 Costa Rican taxa from 5 genera (Crotalus, Bothrops, Atropoides, Cerrophidion, and Bothriechis of pitvipers were investigated using high-throughput 454 pyrosequencing. 100,394 out of 330,010 masked reads produced significant hits in the available databases. 5.165,220 nucleotides (8.27% were masked by RepeatMasker, the vast majority of which corresponding to class I (retroelements and class II (DNA transposons mobile elements. BLAST hits included 79,991 matches to entries of the taxonomic suborder Serpentes, of which 62,433 displayed similarity to documented venom proteins. Strong discrepancies between the transcriptome-computed and the proteome-gathered toxin compositions were obvious at first sight. Although the reasons underlaying this discrepancy are elusive, since no clear trend within or between species is apparent, the data indicate that individual mRNA species may be translationally controlled in a species-dependent manner. The minimum number of genes from each toxin family transcribed into the venom gland transcriptome of each species was calculated from multiple alignments of reads matched to a full-length reference sequence of each toxin family. Reads encoding ORF regions of Kazal-type inhibitor-like proteins were uniquely found in Bothriechis schlegelii and B. lateralis transcriptomes, suggesting a genus-specific recruitment event during the early-Middle Miocene.

    In 1995 Midtkraft Power Company built Denmark's second offshore wind farm as a demonstration project. The project purpose is first of all to investigate the environmental aspects of offshore wind energy. The two primary objects are to study the impact on bird life and to test different methods for predicting the visual effect. The wind farm consists of 10 pitch-regulated Vestas V39 500 kW wind turbines placed on box caisson foundations in a shallow water area 6 km east of Jutland. The project has been implemented successfully under a very narrow time schedule, and during the first 6 months in operation, the production has been approx. 30% higher than expected. (author)

  1. The potential of wind farms

    1992-01-01

    Summaries of papers presented at the European wind energy conference on the potential of wind farms are presented. It is stated that in Denmark today, wind energy provides about 3% to the Danish electricity consumption and the wind power capacity is, according to Danish wind energy policy, expected to increase substantially in the years to come. A number of countries in Europe and elsewhere are making significant progress in this repect. Descriptions of performance are given in relation to some individual wind farms. The subjects covered concern surveys of national planning and policies regarding wind utilization and national and global development of wind turbine arrays. Papers also deal with utility and project planning, wind prediction and certification, wind loads and fatigue, wakes, noise and control. (AB).

  2. Grid Integration of Wind Farms

    2003-07-01

    This article gives an overview of grid integration of wind farms with respect to impact on voltage quality and power system stability. The recommended procedure for assessing the impact of wind turbines on voltage quality in distribution grids is presented. The procedure uses the power quality characteristic data of wind turbines to determine the impact on slow voltage variations, flicker, voltage dips and harmonics. The detailed assessment allows for substantially more wind power in distribution grids compared with previously used rule-of-thumb guidelines. Power system stability is a concern in conjunction with large wind farms or very weak grids. Assessment requires the use of power system simulation tools, and wind farm models for inclusion in such tools are presently being developed. A fixed-speed wind turbine model is described. The model may be considered a good starting point for development of more advanced models, hereunder the concept of variable-speed wind turbines with a doubly fed induction generator is briefly explained. The use of dynamic wind farm models as part of power system simulation tools allows for detailed studies and development of innovative grid integration techniques. It is demonstrated that the use of reactive compensation may relax the short-term voltage stability limit and allow integration of significantly more wind power, and that application of automatic generation control technology may be an efficient means to circumvent thermal transmission capacity constraints. The continuous development of analysis tools and technology for cost-effective and secure grid integration is an important aid to ensure the increasing use of wind energy. A key factor for success, however, is the communication of results and gained experience, and in this regard it is hoped that this article may contribute.

    2018-04-18

    Agriculture is recognised as a highly dangerous sector worldwide, hence the use of evidence-based solutions to address injury related incidents are critical to prevention. The main of this paper is to determine the potential for prevention by use of existing controls based on deaths data from 2001-2016. This study assesses data from the National Coroner's Information System for the period 2001-2016 in regards to unintentional farm injury deaths in Australia (n = 1,271). The six leading causes of death (tractors, quads (ATVs), water/dams, farm utilities (pickups), motorcycles and horses: n=644), are reviewed against existing evidence-based practice recommendations to ascertain the potential capacity to prevent and/or ameliorate the severity of the fatal incidents. Projections of economic costs associated with these incidents in the past five years (2012-2016) are outlined. Of the cases involving the six leading agents (n=644), 36% (n=235) have the potential to be prevented with the use of designated evidence-based controls. Meanwhile the costs attributed to deaths involving the six leading agents in the 2012-2016 period, exceeded AU$313 million. Farm injury incidents and their related economic costs, can be reduced by enhanced adoption of the existing evidence-based controls. SO WHAT?: Farm safety efforts in Australia require re-invigoration and funding to focus on evidence-based controls supported by enforcement to attain maximum impact.

    Radiation workers are healthier than the average person in the general population and appear to be as healthy as workers in other ΣsafeΣ industries. It is, however, assumed that there is no safe dose of radiation and that any exposure to radiation will cause a small increase in the incidence of cancer, this increase being directly proportional to the total radiation dose. On the basis of the risk estimates given by ICRP, radiation exposures up to 1 rem per year for 47 years are predicted to cause fewer work-related deaths than expected for the average worker in Canadian industry. Radiation exposures of 5 rem per year from age 18 to 65 would result in predicted risk which is about four times higher than that for most workers in Canada and might increase the chances of death before age 75 to nearly the same level as for the average member of the general public.

    Gingivitis is a common oral health problem. Untreated gingivitis may progress to periodontitis, a common cause of tooth loss. The prevalence of gingivitis and calculus among Puerto Rican children is unknown. Understanding this prevalence can support early public health preventative strategies. This study aims to estimate the prevalence of gingivitis and calculus among 12-year-old Puerto Ricans by health region and to explore differences in distribution by school type (proxy for socio-economic status) and gender. A probability-based sample of 113 schools was selected proportional to enrollment size and stratified by health region, school type, and gender. Two trained examiners evaluated the presence of gingivitis and both supragingival and subgingival dental calculus. Gingivitis was defined as the presence of gingival bleeding upon gentle probing (BOP) in at least one site, and the extent of the problem was classified according to the percentage of teeth whose gingiva presented BOP (limited: 25-49% of the teeth tested; extensive: >50% of teeth tested). Logistic and linear regression models, adjusted for health regions, were used to compare gingivitis and calculus prevalence and extent between genders and school types. Gingivitis was found in 80.41% of the 1586 children evaluated. Urban-public schoolchildren had a slightly higher prevalence (83.24%) compared to private (79.15%, p = 0.16); those in rural-public (77.59%) and private schools had similar prevalence (p = 0.15). Extensive gingivitis was present in 60.81% of all children. The mean percentage of sites presenting BOP (BOP%) was 17.79%. Rural and urban public schoolchildren presented significantly higher BOP% compared to children from private schools (p = 0.0005, p = 0.002, respectively). Dental calculus was detected in 61.59% of the sample, boys presenting significantly higher (p = 0.005) total and supragingival calculus. Rural-public schoolchildren had a significantly higher prevalence of

    The Department of Energy (DOE) is in the process of defining the magnitude and diversity of Decontamination and Decommissioning (D&D) obligations at its numerous sites. The DOE believes that existing technologies are inadequate to solve many challenging problems such as how to decontaminate structures and equipment cost effectively, what to do with materials and wastes generated, and how to adequately protect workers and the environment. Preliminary estimates show a tremendous need for effective use of resources over a relatively long period (over 30 years). Several technologies are being investigated which can potentially reduce D&D costs while providing appropriate protection to DOE workers. The DOE recognizes that traditional methods used by the EPA in hazardous waste site clean up activities are insufficient to provide the needed protection and worker productivity demanded by DOE D&D programs. As a consequence, new clothing and equipment which can adequately protect workers while providing increases in worker productivity are being sought for implementation at DOE sites. This project describes the development of an Advanced Worker Protection System (AWPS) which will include a life-support backpack with liquid air for cooling and as a supply of breathing gas, protective clothing, respirators, communications, and support equipment.

    The apparent link recently found by Dr. Najarian between cancer among workers at a US Naval dockyard where up to 5000 civilian employees have been exposed to low dose irradiation while servicing nuclear ships and their radiation exposure is discussed. The study has revealed that 38.4% of the deaths of nuclear workers at the Portsmouth Naval Shipyard in New Hampshire were caused by cancer while the comparable rate for non-nuclear shipyard workers was 21.7% and the national average in the United States is 18%. The Portsmouth study, launched in October 1977, was based on a survey of 1722 death certificates of shipyard employees and interviews with 592 next-of-kin. In addition the results show that the rate of leukaemia of the shipyard workers was 450% higher than that of the general population, and the incidence of lymph gland cancers was 125% higher than the national rate. The most startling statistics compared mortality among workers aged 60 to 69. In this age group nearly 60% of the nuclear employees had died of cancer, while the cancer death rate among non-nuclear workers was only 26%. If these results are confirmed present ideas concerning the effects of low doses of radiation must be challenged. (U.K.)

    Full Text Available Background: Blood sucking mites are important avian ectoparasites which being found on bird species worldwide. Their presence are problematic for the producers either through potential direct effects on weight gain, egg produc­tion, sperm production in roosters or as nuisance pests on worker handle hens and eggs. The aim of this study was pointing out of the status of haematophagus mites."nMethods: Eight caged layer and four breeder flocks were visited, monitoring for the presence of chicken mites per­formed by removing and examining debris from poultry house, infested nesting material collected into zip lock plas­tic bags and at least 20 birds were also randomly selected to examine the presence of chicken mites. Mites obtained from each population were mounted in Hoyer,s medium on microscope slides and identified. All eight caged layer and four breeder flocks were inspected, which were infested with chicken blood feeding mites."nResults: Massive infestations of Dermanyssus gallinae were common with huge numbers of parasites on birds, cages and the conveyor belts for egg. Only one farm from Mazandaran Province was infested to Ornithonyssus bursa."nConclusion: Dermanyssus gallinae was the most prevalent blood feeder mite in the breeder and caged layer flocks in Iran, while O. bursa was reported as a first record, which found only in a breeder flock in Mazanderan Province. It seems that its presence is limited into the area which affected by both warm and humid environmental conditions.  Keywords: Dermanyssus gallinae, Ornithonyssus bursa, Poultry, Iran

    Full Text Available Aim: To investigate the status, problems and prospects of Japanese quail (Coturnix coturnix japonica farming in selected areas of Bangladesh. Materials and Methods: The study was conducted in 14 districts of Bangladesh, viz., Dhaka, Narayanganj, Munshiganj, Mymensingh, Netrakona, Faridpur, Jessore, Khulna, Satkhira, Kushtia, Bogra, Naogaon, Comilla, and Sylhet during the period from July 2011 to June 2012. A total of 52 quail farmers were interviewed for data collection using a structured questionnaire. Focus group discussions were also carried out with unsuccessful farmers and those want to start quail farming. Workers of quail farms, quail feeds and medicine suppliers, quail eggs and meat sellers were also interviewed regarding the issue. Results: Out of 52 farms, 86.5% were operated by male, 67.3% farmers did not receive any training and 92.3% farmers had no earlier experience of quail farming although 58.0% farmers primary occupation was quail farming. Most of the farms (63.4% were mixed in type having ≤5000 birds of two or three varieties. About 80.7% farms were operated separately round the year with no other poultry and 83.0% farmers wanted to expand their farming. The average pullet weight 14.5±0.12, 11.0±0.07, 12.0±0.22, and 12.8±0.17 g; age at the first lay 46.0±0.04, 42.0±0.31, 42.0±0.09, and 45.2±0.05 days; rearing period 15.0±0.01, 12.0±0.14, 15.0±0.32, and 15.2±0.18 months; culling period 15.5±0.14, 13.0±0.06, 15.0±0.03, and 15.4±0.26 months were for layer, parent stock, hatchery, and mixed farms, respectively. Most of the layer farms had an average egg production of ≤5000/day and net profit BDT 0.75/egg. However, an average number of birds, hatchability and net profit per day-old-chick were ≤5000, 76.8% and BDT 2.75, respectively, in the hatchery. Broiler quails were sold at 30 days with mean weight of 110.8 g and net profit BDT 9.02/bird. The major constraints of quail farming were higher feed price

    The EQM Research, Inc., portable test kit was evaluated as a surveillance tool for blood cholinesterase levels among migrant workers and their children. Laboratory validation demonstrated a linear relationship between the reference Ellman and kit methods (Ellman = 0.95 x kit result + 0.82, r2 = 0.98). Pre- and post-season cholinesterase levels measured in 70 farm workers were within normal ranges, but significantly different at 28.5 and 29.7 U/g Hb, respectively (paired t-test, p = 0.014). Results from 98 migrant farm worker children and a comparison group of 53 age-matched non-agricultural children showed that cholinesterase levels were not significantly different between the agricultural and non-agricultural children (ANOVA, p = 0.69). These data demonstrate that a portable test kit can provide useful data pesticide exposures when measurements are made in a temperature-controlled setting.
